    Regulation of Fuels and Fuel Additives: Modifications to 
    Standards and Requirements for Reformulated and Conventional Gasoline
    
    AGENCY: Environmental Protection Agency (EPA).
    
    ACTION: Proposed rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: Through the amended Clean Air Act of 1990, Congress mandated 
    that EPA promulgate regulations requiring that gasoline sold in certain 
    areas be reformulated to reduce vehicle emissions of toxic and ozone-
    forming compounds. The EPA published rules for the certification and 
    enforcement of reformulated gasoline (RFG) and provisions for non-
    reformulated or conventional gasoline on February 16, 1994.
        Based on experience gained since the promulgation of these 
    regulations, EPA is proposing a variety of changes to the regulations 
    relating to emissions standards, emissions models, compliance related 
    requirements and enforcement provisions. The proposed changes involve 
    both the reformulated and conventional gasoline programs. Many of the 
    changes codify guidance issued by the Agency since the initial adoption 
    of these gasoline programs. These changes are in the nature of minor 
    adjustments to the structure of these programs. The emissions benefits 
    achieved from reformulated gasoline will not be reduced.
    
    DATES: The comment period on this proposed action will close August 11, 
    1997, unless a hearing is requested, in which case the comment period 
    will close 30 days after the close of the public hearing. EPA will 
    conduct a hearing (date and location to be announced) if a request for 
    such is received by July 18, 1997.
    
    ADDRESSES: Written comments on this proposed action should be addressed 
    to Public Docket No. A-97-03, Waterside Mall (Room M-1500),

    II. General Fuels Provisions
    
    A. Test Methods (Sec. 80.3; RFG Test Methods Sec. 80.46)
    
    1. Replacement of Lead and Phosphorus Test Methods with Industry 
    Standard Test Methods (Secs. 80.3 (a) and (b))
        40 CFR part 80, appendices A and B, specify the test methods that 
    are used for determining, respectively, the phosphorus content and the 
    lead content of gasoline. Today's proposal would remove appendices A 
    and B and add Secs. 80.3 (a) and (b) which would require the use of 
    ASTM method D 3231-94 for phosphorus and methods D 3237-90 or D 5059-92 
    for lead. The phosphorus and lead test methods are used primarily to 
    determine compliance with the standards under Secs. 80.22 and 80.23, 
    dealing with the unleaded gasoline program. Also, under 
    Sec. 80.41(h)(1), RFG may contain no heavy metals. As a result, the 
    proposed lead test method would be used for determining the presence of 
    this heavy metal in RFG.
        The test methods in appendices A and B of 40 CFR part 80 originally 
    were adopted from ASTM standard test methods. Over time, however, ASTM 
    has updated their test methods, while EPA has not. EPA believes the 
    current ASTM test methods are equivalent to the methods currently in 
    the regulations, and are more consistent with the test methods 
    regulated parties normally use for commercial purposes. As a result, 
    the proposed test methods would be appropriate for determining 
    compliance with the provisions of 40 CFR part 80.
        EPA believes there would be little additional burden on the 
    regulated industry if the proposed phosphorus and lead test methods 
    were adopted. Initially, EPA understands that the proposed test methods 
    are the current industry standard test methods, so most gasoline 
    testing laboratories already are equipped to conduct the proposed test
    
    [[Page 37340]]
    
    methods. In addition, there is no requirement for regulated parties to 
    test their gasoline for phosphorus or lead under either the unleaded 
    gasoline or the RFG regulations, so parties would not be obligated to 
    use the proposed test methods at all. Rather, the phosphorus and lead 
    test methods in the regulations are used by EPA to determine if 
    gasoline meets standards for these metals. EPA or a regulated party 
    also could use non-regulatory phosphorus or lead test methods. However, 
    in an enforcement proceeding, the results from non-regulatory test 
    methods would only constitute evidence of the results that would have 
    been obtained if the regulatory test method had been conducted on the 
    gasoline at issue.
    2. Reformulated Gasoline Test Methods (Secs. 80.46 (a) Through (g))
        In Sec. 80.46, test methods were specified for the measurement of 
    the regulated properties of reformulated gasoline. Many of the test 
    methods designated in the original rule were consensus standards, 
    prepared and maintained by ASTM. Since the original issuance of the 
    rule, some of these methods have been updated. EPA is now proposing to 
    replace the current regulatory methods with the updated versions of 
    these methods for the measurement of sulfur, olefins, and distillation 
    parameters. In addition, EPA is proposing an alternative test method 
    (ASTM D 5453-93) for determining the sulfur content in conventional 
    gasoline until September 1, 1998. This proposed alternative test method 
    is discussed in Section VI.B.6. The proposed updated methods all are 
    finally approved ASTM test methods. In addition, ASTM has developed a 
    method (ASTM D 5599-95) that is the same as the procedure for the 
    measurement of oxygenates at Secs. 80.46(g) (1) through (8), and EPA 
    proposes to replace Secs. 80.46(g) (1) through (8) with a reference to 
    the ASTM method. For the measurement of RVP, EPA proposes to eliminate 
    the appendix containing EPA Method 3 (appendix E), and designate ASTM D 
    5191-96 as the required method, with the exception that the correlation 
    equation as described in EPA Method 3 must be used in place of the 
    correlation equation described in ASTM D 5191-96. ASTM D 5191-96 is 
    identical to the RVP test method in appendix E when the correlation 
    equation from EPA Method 3 is used with the ASTM method. In all cases, 
    these changes do not amount to a deviation in method, or significant 
    change in procedure. Most of the ASTM changes revolve around 
    improvements in quality statements. The inclusion of ASTM D 5599-95 for 
    oxygenates is the result of ASTM preparing a test method that is 
    consistent with that previously defined in the Federal Register.
        The test method previously designated for benzene, ASTM D 3606, has 
    been updated since the original publication of the rule. However, the 
    parameters must be adjusted to allow for the resolution of ethanol and 
    methanol from the benzene. In addition, the EPA GC/MS method has been 
    demonstrated through ASTM round-robin testing to be an equivalent 
    method for the measurement of benzene. Since the use of the EPA GC/MS 
    method would allow two parameters (benzene and aromatics) to be 
    performed with a single test, EPA believes the use of the EPA GC/MA 
    method for the measurement of benzene would result in a reduced burden 
    to the regulated industry, and, therefore, is proposing to allow its 
    use as an alternate test procedure for the measurement of benzene in 
    gasoline.
    3. Butane Test Methods (Sec. 80.46(h))
        Blendstocks require the same full set of parameter measurements as 
    reformulated gasoline, since final properties must be extrapolated for 
    all final blends. When butane designated for blending must be tested, 
    the designated methods are generally not applicable, since the 
    properties for butane typically fall outside the scope of the methods. 
    Therefore, EPA is proposing to designate several test methods 
    specifically for butane blendstock testing. ASTM D 2163-91 and D 5623-
    94 have been identified as suitable methods for the measurement of 
    light hydrocarbons and sulfur respectively. The Gas Producers 
    Association (GPA) has developed a method for the measurement of benzene 
    and aromatics in butane. This method is GPA 2186-95. EPA is not 
    proposing to designate a method for measuring olefins in butane. No 
    consensus method currently exists for measuring total olefins in butane 
    blendstocks. ASTM D 2163-91 will measure the lighter olefins, but not 
    any heavier ones in the mix. EPA has identified a proprietary method, 
    known as the Wasson ECE 383-01 method, which measures all of the 
    olefinic compounds in the blendstock. This method is not a consensus 
    standard, but is of the type that would be acceptable, due to its 
    ability to measure total olefins.
    4. Volatility Test Methods (Secs. 80.3 (c) and (d))
        As discussed above, for the measurement of RVP, EPA proposes to 
    eliminate the appendix containing EPA Method 3 (appendix E) and 
    designate ASTM D 5191-96 as the regulatory method, with the exception 
    that the correlation equation as described in EPA Method 3 must be used 
    in place of the correlation equation described in ASTM D 5191-96.
        The measurement of alcohols, especially ethanol, for the volatility 
    rule has been described in detail in appendix F of 40 CFR part 80. In 
    this appendix, Method 1 describes a water extraction method, and Method 
    2 details a chromatographic procedure (an older version of ASTM D 
    4815.) In an effort to harmonize methods, EPA believes it would reduce 
    the testing burden to allow test methods that are consistent with the 
    reformulated gasoline rule. As a result, EPA proposes to eliminate 
    Appendix F and designate ASTM D 5599-95 as the method for the 
    measurement of alcohols in gasoline for the purpose of complying with 
    the volatility regulations. Consistent with the reformulated gasoline 
    rule, the use of ASTM D 4815-94a will be allowed as an alternate as 
    long as this use is allowed under the reformulated gasoline rule.
    5. Diesel Fuel Test Methods (Secs. 80.3 (e), (f), and (g))
        When the diesel sulfur rule was originally published by EPA, 
    several methods were included for the measurement of the regulated 
    properties. Included in these properties are sulfur concentration, 
    cetane index, and aromatic content. The current designated test for 
    sulfur is ASTM D 2622-87, with D 4294-83 being an allowable alternate. 
    As discussed above, EPA proposes to substitute the current regulatory 
    test method for sulfur, D 2622-87, with the latest version of this 
    method, D 2622-94. EPA also proposes to substitute the alternate method 
    for determining sulfur content in diesel fuel, D 4294-83, with the 
    latest version, D 4294-90(1995), and substitute the current test method 
    for cetane index, ASTM D 976-80, with the latest version, D 976-91.
        The test for aromatics in diesel had been designated to be ASTM D 
    1319-88. EPA recognizes that ASTM describes this test as inadequate for 
    the measurement of the aromatic content in diesel fuel. For some time, 
    EPA has been performing ASTM D 5186 in parallel with D 1319, and found 
    D 5186 to be superior in both precision and accuracy. The primary 
    difficulty in changing from the use of D 1319 to D 5186 to measure 
    compliance lies in the units reported by the two methods. The 
    regulation specifies a limit on the aromatic content in volume per-
    cent, coincidentally the same units reported
    
    [[Page 37341]]
    
    by D 1319. Unfortunately, D 5186 reports results in mass per-cent. In 
    order to comply with the regulation, these results must be converted to 
    volume per-cent. EPA proposes to apply a conversion factor to the 
    results. The equation to be used for the conversion of mass per-cent 
    diesel aromatics to volume per-cent diesel aromatics is:
    
    Vol% = (Mass% * 0.916) + 1.33
    
        Where Mass% refers to the output from D 5186-96, the SFC test.
        This equation is identical to that used by CARB in their conversion 
    of mass per-cent results to volume per-cent results for the affirmation 
    of regulatory limits.
        This change should not impose any additional financial burden on 
    industry, since it is not a required test. The option of measuring 
    aromatics was originally placed in the rule to allow an alternate to 
    the requirement that low sulfur fuels meet a minimum requirement of a 
    40 cetane index. The intent was to regulate aromatic content, and it 
    was found that some fuels with high napthenic content could actually be 
    very low in aromatics, yet still not meet the 40 cetane index level. 
    The option to test for aromatic content would only be exercised if a 
    fuel fails to meet the required cetane index level, a relatively 
    infrequent occurrence.
    6. Table of Test Methods
        The following table sets out the test methods currently required 
    under the fuels regulations at 40 CFR part 80, and the corresponding

    B. Gasoline and Diesel Fuel Sampling Procedures (Proposed 
    Sec. 80.8)
    
        40 CFR part 80, Appendices D and G, specify sampling procedures for 
    gasoline and diesel fuel for all motor vehicle fuel programs under 40 
    CFR part 80, including the programs for unleaded gasoline, gasoline 
    volatility, diesel sulfur, RFG, and anti-dumping. Today's proposal 
    would replace the sampling procedures in appendices D and G with the 
    following ASTM standard practices:
         D 4057-95, ``Standard Practice for Manual Sampling of 
    Petroleum and Petroleum Products;''
         D 4177-95, ``Standard Practice for Automatic Sampling of 
    Petroleum and Petroleum Products;''
         D 5842-95, ``Standard Practice for Sampling and Handling 
    of Fuels for Volatility Measurements;'' and
         D 5854-95, ``Standard Practice for Mixing and Handling of 
    Liquid Samples of Petroleum and Petroleum Products.''
        Appendices D and G were adopted from the 1981 version of D 4057. 
    Over time, however, ASTM has updated D 4057, and these changes are not 
    reflected in Appendices D and G. For example, appendix D addresses the 
    collection of samples from a ``tap'' in the shell of a petroleum 
    storage tank. The current requirement under appendix D, reflective of D 
    4057-81, requires that taps extend at least three feet into the storage 
    tank. See, para. 11.3.1.1 of appendix D. However, tap extensions are 
    necessary only for heavy petroleum products (and not for gasoline and 
    diesel fuel), and, furthermore, tap extensions are not possible with 
    floating roof storage tanks that are commonly used today. As a result, 
    EPA and regulated parties currently agree to waive the tap extension 
    requirement on a case-by-case basis. Under D 4057-95 sampling tap 
    extensions are not required for light petroleum products such as 
    gasoline and diesel fuel, so that if this ASTM procedure were adopted 
    the tap extension issue would be resolved for all cases.
        EPA is proposing to adopt three ASTM methods in addition to D 4057-
    95 in order to include procedures that address a broad scope of 
    sampling situations that are relevant to EPA's motor vehicle fuels 
    programs. D 4177-95 deals with automatic sampling of petroleum 
    products, which is relevant under the anti-dumping regulations for 
    refiners who produce conventional gasoline using an in-line blending 
    operation where automatic sampling is necessary. Similarly, D 5842-95 
    deals with sampling and sample handling for volatility measurement, 
    which is relevant to determining compliance with the volatility 
    standards in Sec. 80.27 and the RFG standards in Sec. 80.41. Last, D 
    5854-96 deals with the creation of composite samples, which is relevant
    
    [[Page 37342]]
    
    under the RFG and anti-dumping programs in certain situations involving 
    imported gasoline where the gasoline from multiple ship compartments is 
    treated as a single batch.
        EPA believes it is appropriate to replace Appendices D and G with 
    ASTM standard practices. The current ASTM practices reflect up to date 
    procedures, which if followed would result in improved sample quality 
    for regulatory purposes. In addition, the adoption of industry standard 
    procedures would reduce regulatory burden because parties would be able 
    to follow their customary practices when meeting regulatory 
    requirements.
    
    III. RFG and Anti-Dumping Standards/Models
    
    A. Standards and Requirements for Compliance (Secs. 80.41 and 80.101)
    
    1. Averaging Per-Gallon Minimum Standards for NOX 
    (Secs. 80.41 (d) and (f); Sec. 80.68(b)(1)(iv))
        Reduction of NOX emissions is a prominent feature of 
    Phase II of the Reformulated Gasoline Program which goes into effect on 
    January 1 of 2000 (Phase I provides control at a ``no NOX 
    increase'' level). The Phase II standard for refiners choosing to 
    comply on average (requiring a 6.8% reduction from baseline during the 
    high ozone season) sets the level of NOX emission reduction 
    required on average by these refiners. Thus, for refiners who choose to 
    average, the averaging standard effectively controls the overall 
    environmental benefit contributed to the program by these refiners.
        In addition to the average NOX standards, though, there 
    are also per-gallon minimum reduction standards for refiners that 
    choose to average (not to be confused with standards for overall 
    compliance on a per-gallon basis). The averaging minimum standard in 
    Phase II requires that each gallon (batch) of RFG in the high ozone 
    season has at least a 3% reduction from the statutory baseline; the 
    corresponding Phase I standard holds any increase over statutory 
    baseline for a batch to 2.5%. Less stringent minimum standards apply 
    outside of the high ozone season in Phase II. The per-gallon minimum 
    standards are in addition to the year-long average standard of a 
    refinery's output of a given type of RFG and these minimum standards 
    set the NOX reduction which must be achieved by each batch 
    (and therefore each gallon) of RFG.
        These NOX per-gallon minimum standards were not put in 
    place to provide any incremental environmental benefit beyond that 
    provided by the average standard, but rather to ensure an even 
    distribution of program benefits from area to area and through time. 
    This primary reason for the averaging per-gallon minimum standards (for 
    NOX and other parameters as well) was discussed in the 
    enforcement section of the preamble to the RFG final rule (Section 
    VII). An additional but secondary objective of the minimum standard was 
    to augment the ability of enforcement authorities to detect non-RFG 
    gasoline being illegally sold in RFG areas. For reasons that will be 
    discussed more fully below, EPA is proposing to eliminate the per-
    gallon minimum standards for NOX and to accomplish the same 
    objectives that these standards would have accomplished by 
    substantially expanding the number of area-by-area surveys of RFG 
    emission performance required to be conducted by refiners choosing to 
    average. EPA is not proposing any change to the averaging standard for 
    NOX.
    
    The Problem With the Per-Gallon NOX Minimums
    
        When EPA imposed the per gallon minimum standards, data did not 
    exist to adequately assess the variability, within refineries' output, 
    of NOX quality or the factors that affect it across all of 
    the batches of gasoline produced in a year.
        Representatives of the gasoline refining industry (the American 
    Petroleum Institute (API), the National Petroleum Refiners Association 
    (NPRA) and representatives of various of their member companies) have 
    presented data to EPA 1 showing that NOX 
    performance of actual RFG retail samples varies substantially by octane 
    grade and from batch to batch 2 within a grade. The 
    processes involved in gasoline production result in a broad bimodal 
    3 distribution of NOX quality, with premium 
    batches showing characteristically lower NOX emissions and 
    regular batches, with their higher levels of sulfur and olefins, 
    showing higher NOX emissions. 4 These data on 
    gasoline produced under the simple model requirements showed a very 
    substantial proportion of regular grade RFG samples that would have 
    failed to meet the Phase I minimum reduction standard that applies 
    beginning in 1998.
    ---------------------------------------------------------------------------
    
        \1\ Industry representatives met with EPA personnel on January 
    14, 1997 and presented a graphical analysis which can be found in 
    the docket for this rulemaking. Docket Number A-97-03, Item Number 
    II-E-1.
        \2\ Since these were retail samples, they could not truly 
    reflect batch-to-batch variability due to the intermingling of 
    gasolines from different batches, and even from different sources, 
    in the distribution system.
        \3\ A bimodal distribution here refers to one that has two 
    distinct frequency peaks or two values around which a large number 
    of batches will gather.
        \4\ Engineering judgment would lead to a conclusion that a broad 
    distribution of NOX quality differing markedly between 
    premium and regular gasoline grades would exist in the gasoline 
    pool. First, NOX quality under EPA's complex model is 
    primarily a function of sulfur and olefin content in the gasoline. 
    Thus, differences in either of these properties would result in 
    differences in NOX quality. Second, in the refinery, 
    processes which typically contribute large volumes to the regular 
    gasoline grade are often high in sulfur and olefins, whereas 
    processes contributing heavily to the premium gasoline pool are 
    often very low in olefins and sulfur. For example, the fluid 
    catalytic cracker (FCC) unit in a refinery breaks large molecules 
    into smaller ones and is the ``workhorse'' of most refineries and 
    the largest contributor of any refinery unit to the gasoline pool. 
    The gasoline produced by the FCC unit is highly olefinic, and, 
    depending upon the crude oil source for the refinery, usually very 
    high in sulfur. FCC gasoline also possesses octane quality 
    consistent with regular gasoline. For this reason and since regular 
    gasoline is typically the highest volume product of U.S. refineries, 
    most of the product produced by the FCC is used in the production of 
    regular gasoline. On the other hand, premium gasolines, which differ 
    from regular grades primarily in the higher octane quality they 
    possess, contain lower amounts of FCC streams and higher levels of 
    high-octane aromatic streams produced by catalytic reformers. Such 
    streams, called reformate, are extremely low in olefins and also 
    very low in sulfur. Thus, a much lower level of sulfur and olefin 
    content and therefore, better NOX quality, is found in 
    the premium pool as compared to the regular pool. (A 1989 study of 
    blendstocks used to produce U.S. gasoline found FCC blendstocks 
    possessing an average octane quality of 86.4, an average olefin 
    content of 29.1 percent, and an average sulfur content of 756 parts 
    per million (ppm). The same study found that reformate streams, 
    produced by the reformer, possessed octane quality of 92.6, an 
    olefin content of less than 1 percent and an average sulfur level of 
    55 ppm. See ``NPRA Survey of U.S. Gasoline Quality and U.S. Refining 
    Industry Capacity to Produce Reformulated Gasolines--Part A'', 
    National Petroleum Refiners Association, 1991 Gasoline Study, 
    January, 1991, Docket Number A-97-03, Item Number II-B-1.)
    ---------------------------------------------------------------------------
    
        In order to bring these higher NOX batches of regular 
    RFG into compliance, the refiners suggested that the industry would 
    have to incur substantial additional costs in excess of those 
    calculated in EPA's Regulatory Impact Assessment which EPA relied upon 
    in adopting the standards for RFG in 1993. That assessment of the costs 
    of compliance for NOX was based upon the cost of meeting the 
    average standard, not the per-gallon minimum that applies to refineries 
    that average, which is the subject of this proposal. They further 
    argued that in the absence of a substantial enforcement tolerance to 
    account for the uncertainty of measurement (especially of olefin 
    levels) in downstream enforcement sampling, the bimodal frequency 
    distribution would have to be shifted further than would otherwise be 
    required. While the problem created by the NOX minimum would 
    already be substantial in Phase I with the 1998 introduction of the 
    complex model, the
    
    [[Page 37343]]
    
    refiners suggested that Phase II's tighter minimum standard for 
    NOX in the year 2000 would exacerbate an already very 
    difficult situation, even given the changes made to refinery processes 
    in order to be able to comply with the Phase II average standard.
        The distribution of retail sample data initially presented by the 
    refiners in their general meeting with the Agency described the net 
    result of the product intermingling that occurs in the gasoline 
    distribution system. By describing all of the nation's gasoline taken 
    together, these data could suggest the existence of a problem (high 
    variability with many samples below the minimum reduction standard), 
    but could not indicate much about how widespread the problem is or show 
    what types of refineries are likely to be affected. By examining 
    historical RFG reporting data,5 EPA was able to confirm the 
    general factual basis of the industry analysis. Specifically, the data 
    showed a broad distribution of NOX quality with the premium 
    batches clustered near the high end (high NOX reductions), 
    while regular batches are more spread out with central tendency nearer 
    the low end and many batches falling below the Phase I NOX 
    minimum. Left unanswered by either the industry-supplied information or 
    EPA's own analysis, was the question of whether refiners could exercise 
    any control over the variability and shape of the frequency 
    distribution that was evident in both data sources. In other words, it 
    was not clear what options were available to refineries to remedy the 
    problem.
    ---------------------------------------------------------------------------
    
        \5\ Data on the characteristics of gasoline batches as they are 
    shipped from the refinery are submitted to EPA as part of the 
    reporting requirements of the RFG regulations. An aggregated 
    analysis that protects the confidentiality of individual refiners' 
    data can be found in the docket for this rulemaking. Docket Number 
    A-97-03, Item Number II-A-5.
    ---------------------------------------------------------------------------
    
        To provide additional insights, EPA and a refinery expert from the 
    Department of Energy met separately with individual refiners in order 
    to look at batch data from single refineries using differing gasoline 
    production approaches. The refineries represented by the companies EPA 
    met with comprised a very diverse group. They varied with regard to 
    size, general level of technology, control over inputs, historical 
    product slate, and other characteristics. EPA focused the agenda for 
    these meetings on three basic questions: (1) For each separate 
    refinery, what is the batch-to-batch distribution of NOX 
    quality by grade and season, (2) what are the causes of the variability 
    that is observed in the historical data--which parameters account for 
    the variability in NOX, and what caused them to vary the way 
    they did, and (3) how do refinery managers plan to meet the 
    NOX minimum standards in the absence of a substantial 
    enforcement tolerance or regulatory relief.
        The general picture of the broad bimodal distribution of gasoline 
    NOX quality by grade that was developed from overall 
    industry analyses and examination of our own data was generally 
    confirmed in these more detailed meetings.
        As might be expected, individual facilities varied considerably in 
    the size of the challenge posed by the NOX minimum standards 
    and they expected to address that problem with varying strategies. The 
    pattern that emerged from all of these discussions was that refiners 
    intend to pursue the least capital-intensive solutions wherever 
    possible, even to the extent of incurring substantial additional 
    production costs in the short run. Although the strategies articulated 
    in these meetings 6 did not precisely conform to the pattern 
    expected by the industry associations (shifting the entire distribution 
    of NOX quality), they seemed to lead to the same result 
    economically--excess costs in producing RFG beyond the costs of making 
    the refinery's average conform to the average standard. Any major 
    expansion of the RFG program as a result of areas opting into the 
    program could further increase the costs of meeting the minimum 
    standard.
    ---------------------------------------------------------------------------
    
        \6\ Some general examples of the approaches which are likely to 
    be used to bring sub-minimum batches above the standard include: 
    Finding another use for the poor NOX quality gasoline or 
    its components (shifting it to conventional gasoline, if that can be 
    done without violating anti-dumping standards, or shifting it to 
    other products) and buying conforming RFG on the spot market to take 
    its place; reblending the poor NOX quality batches with 
    clean blendstocks purchased from the outside to make them conform to 
    the minimum; or simply reducing RFG production.
    ---------------------------------------------------------------------------
    
    Objectives of the NOX Minimum Standards
    
        The primary purpose of the NOX minimum is to assure an 
    even temporal and geographic distribution of the program's 
    environmental benefits. To put this more simply, the minimum is 
    intended to ensure that no area covered by the RFG program will suffer 
    from impaired air quality (possibly resulting in an exceedance of the 
    NAAQS for ozone) as a result of a single refinery's shipping a batch of 
    high NOX gasoline to an area for which it was a primary 
    supplier. An additional, though secondary, purpose of the 
    NOX minimum standards is to provide a tool for detecting the 
    illegal sale of non-RFG gasoline in areas covered by the program. This 
    would work by keeping legitimate RFG above the minimum, while illegally 
    sold non-RFG might fall below the standard.
        Avoiding distribution problems. The RFG regulations incorporated 
    two mechanisms to avoid the unlikely event of an area being 
    shortchanged on NOX quality due to refinery gate averaging--
    the minimum standard and the RFG gasoline quality surveys.7 
    These surveys were specifically intended to guard against uneven 
    distribution of benefits. In the event that the surveys find a covered 
    area to have received less than the intended NOX emission 
    reduction benefits, the regulations provide for a substantial 
    tightening of the average standard--an outcome that would be expensive 
    to the industry and one that it will work hard to avoid. This proposal 
    includes an increase in the number of surveys to be conducted (an 
    additional 20 surveys per year) that should improve the surveillance of 
    gasoline quality on an area-by-area basis.
    ---------------------------------------------------------------------------
    
        \7\ A program of gasoline quality surveys is required to be 
    conducted by refiners that wish to comply on average rather than on 
    a per-gallon basis. The surveys must be done by an independent 
    contractor in accordance with a statistically sound sampling plan 
    approved by EPA. The location and timing of surveys is determined by 
    EPA with minimal advance notice to the industry's contractor. If 
    survey averages fall short of the criteria set out in the 
    regulations, the average standards and/or the minimum standards are 
    made more stringent for subsequent years for all of the refineries 
    that supplied gasoline to the area(s) where the failure occurred.
    ---------------------------------------------------------------------------
    
        Detecting non-conforming gasoline. A detailed examination of 1995 
    and 1996 actual batch-by-batch gasoline quality (NOX 
    performance) shows that the NOX minimum standard is not a 
    very useful tool for detecting contamination of RFG by illegally sold 
    conventional gasoline, since many batches of conventional gasoline, 
    especially premium grade, are in compliance with the minimum standard. 
    Minimum standards for other gasoline characteristics (especially oxygen 
    content and benzene levels) provide far superior capability for 
    determining if contamination by non-complying gasoline has taken 
    place.8 The proposed expansion of the survey program would 
    further enhance these enforcement efforts, since analysis results for 
    survey samples found to be out of compliance with RFG requirements are 
    immediately supplied to EPA's enforcement office.
    ---------------------------------------------------------------------------
    
        \8\ Analysis in support of this conclusion has been placed in 
    the docket for this rulemaking. Docket Number A-97-03, Item Number 
    II-A-6.
    ---------------------------------------------------------------------------
    
    Conclusions and Proposed Regulatory Actions
    
        EPA believes, as a result of the investigations discussed above, 
    that the averaging minimum standards for NOX
    
    [[Page 37344]]
    
    are likely to be costly to the industry as a whole in both phases of 
    the program, and will make the 1998 complex model implementation 
    extremely difficult for a portion of existing refineries. With the 
    additional costs in question, the overall cost of compliance is likely 
    to exceed the cost upon which the standards were based (the cost of 
    meeting the average standard) without providing additional 
    environmental benefits. By increasing the costs of producing RFG, these 
    standards may contribute to a higher cost differential between RFG and 
    conventional gasoline and so pose a significant obstacle to smooth 
    implementation of Phase II of the program. Since the per-gallon minimum 
    standards for NOX do not increase the environmental benefit 
    and their purposes can be as easily served by the RFG surveys, EPA 
    proposes the elimination of these per-gallon minimum standards.
        Since the RFG surveys provide an alternative tool for accomplishing 
    both of the purposes of the NOX per-gallon minimums, it is 
    important that the survey program remain adequate to perform these 
    tasks. The regulations at Sec. 80.68(b)(1) currently prescribe 50 
    surveys beginning in 1998, with adjustments provided for opt-in of 
    additional programs and/or potential survey failures. EPA believes that 
    20 additional surveys would provide significant additional protection 
    of the NOX quality of gasoline in those RFG covered areas 
    with limited sources of supply. Accordingly, EPA proposes that the 
    number of surveys in the initial schedule (Sec. 80.68(b)(1)) for each 
    year beginning in 1998 be expanded by 20. EPA invites comments on this 
    proposed change.
    2. Clarification That Model Limits Constitute Standards (Proposed 
    Sec. 80.41(h)(3) and Sec. 80.78(a)(1)(vi); Revised Sec. 80.101(b)(3))
        Both the simple and the complex models include restrictions on the 
    range of parameter values that may be used with these models. See 
    Secs. 80.42(c) and 80.45(f) for the simple model limits and the complex 
    model limits, respectively. These parameter range limits are included 
    because the simple and complex models have not been shown to accurately 
    predict emissions when parameter values outside the range limits are 
    used. For this reason, Secs. 80.42(c) and 80.45(f) state that the 
    models may not be used for fuels with parameter values that are outside 
    the valid range limits. The complex model specifies different valid 
    range limits for reformulated versus conventional gasoline. Compare 
    Sec. 80.45(f)(1)(i) (complex model range limits for reformulated 
    gasoline) with Sec. 80.45(f)(1)(ii) (complex model range limits for 
    conventional gasoline).
        EPA always has considered the valid range limits to constitute 
    standards that apply to reformulated and conventional gasoline. 
    Gasoline subject to simple or complex model standards must be evaluated 
    for compliance with these standards. Where gasoline has property values 
    outside the valid range limits, it cannot be evaluated and, therefore, 
    it is unlawful to produce and sell such gasoline.
        Today's proposal would clarify that the valid range limits are 
    standards, by citing the valid range limits along with the other 
    standards that apply to reformulated and conventional gasoline. In 
    addition, EPA is proposing to add a provision to the reformulated 
    gasoline prohibitions under Sec. 80.78(a) that addresses the valid 
    range limit standards. This prohibition would clarify that the complex 
    model valid range limits apply not only to reformulated gasoline when 
    produced or imported, but throughout the distribution system as well. 
    The complex model valid range limit standards must be applied 
    downstream of the refinery or importer because complex model standards 
    apply throughout the distribution system, i.e., the VOC and 
    NOX minimum per-gallon emissions performance standards. In 
    order to evaluate reformulated gasoline for compliance with these 
    downstream standards, the gasoline must have parameter values that are 
    within the valid range limits.
        EPA is proposing to promulgate the revisions contained in this 
    rulemaking under the authority of both sections 211 (c) and (k) of the 
    Act, except for the revisions which would include the valid range 
    limits as standards under Sec. 80.41 and Sec. 80.101. EPA proposes to 
    promulgate the revisions concerning the valid range limits under the 
    authority of section 211(k), but not section 211(c). EPA is proposing 
    to promulgate the valid range limits as standards solely for the 
    purpose of ensuring that the models will accurately predict emissions, 
    and not for the independent purpose of achieving emissions reductions 
    from the range limits themselves. As a result, EPA believes that it is 
    not necessary to promulgate the valid range limits as standards under 
    the authority of section 211(c).
    3. Effective Dates for Standard Changes Due to Survey Failures 
    (Sec. 80.41(p))
        Section 80.41(p) states that when a minimum or maximum per-gallon 
    reformulated gasoline standard is changed to be more stringent as a 
    result of a survey failure, the effective date for the new standard is 
    ninety days after EPA announces the new standard. EPA now believes that 
    additional time is necessary in order to ensure an appropriate 
    transition to a new standard as a result of the lag time between the 
    date refiners and importers begin producing gasoline to a new standard, 
    and the date this gasoline displaces the earlier gasoline through the 
    distribution system.
        For this reason, EPA is proposing a staged introduction to a new 
    per-gallon standard, that results from a survey failure. The dates the 
    new standard would be required would be expressed in the number of days 
    after the date EPA announces the new standard: 60 days for gasoline 
    produced at a refinery or imported by an importer; 120 days for 
    facilities downstream of the refinery or importer other than retail 
    outlets and wholesale purchaser-consumers; and 150 days for retail 
    outlets and wholesale purchaser-consumers. Under the proposed approach 
    refiners and importers would have about two months to begin meeting the 
    new standard, downstream parties such as terminal operators then would 
    have about two months to transition to the new standard after shipments 
    of gasoline meeting the new standard begin, and retailers and wholesale 
    users would have about one month to transition after terminals must 
    begin shipping gasoline meeting the new standard.
        EPA believes the times proposed for these stages are consistent 
    with current industry practice for transitioning to new standards, such 
    as the transition to meet the summertime high ozone season standards 
    each spring. For example, terminals supplying RFG must have gasoline 
    that meets the VOC-control standard beginning on May 1 each year, and 
    retailers and wholesale purchaser-consumers in RFG areas must meet the 
    VOC-control standard beginning about one month later, on June 1.
        Refiners must begin producing VOC-controlled RFG early enough 
    before May 1 that the gasoline distribution system through the terminal 
    level can transition from non-VOC-controlled gasoline to VOC-controlled 
    gasoline by May 1. The date when particular refiners begin producing 
    VOC-controlled RFG each year varies depending on factors such as the 
    time necessary to transport gasoline from the refinery to the 
    terminals, and the rate of turnover at the terminal. However, EPA 
    believes that most long-distance distribution systems are able to 
    transition within 60 days of the date refiners begin shipping gasoline 
    meeting the new standard.
    
    [[Page 37345]]
    
        EPA is able to enforce the VOC-control standard at refineries based 
    on the refiners' batch reports to EPA that identify gasoline batches as 
    either VOC-controlled or non-VOC-controlled; the VOC-control standards 
    apply only to batches that are identified as VOC-controlled. However, 
    there is nothing in the refiners' batch reports to EPA that identifies 
    the per-gallon minimum and maximum standards to which the gasoline is 
    subject. As a result, EPA must rely on a date certain on which the new 
    standard applies at the refinery. Moreover, EPA believes this date must 
    be sufficiently earlier than the date the new standard applies at the 
    terminals in order to ensure the availability to terminals of gasoline 
    meeting the new standard for the terminals' transition. EPA also 
    believes that 60 days is an appropriate length of time for terminal 
    transitions, based on experience with VOC-control transitions.
    
    B. Complex Model (Sec. 80.45)
    
    1. Proper E300 Value for the Edge Target Fuel for Use in Complex Model 
    Extrapolation (Sec. 80.45(c)(1)(iv)(C)(6))
        The Complex Model as described in Sec. 80.45 includes provisions 
    for extrapolations beyond the limits of the data upon which the model 
    was based. The limits of the data define the ``allowable range'' which 
    represents the range of fuel parameters within which the Complex Model 
    equations are directly applicable, and outside of which extrapolation 
    must be used up to the limits of the model.9 These 
    extrapolations take the form of intricate equations and a series of 
    conditions for use of those equations. Among other things, the 
    conditions associated with extrapolation direct Complex Model users to 
    determine properties for an ``edge target fuel.'' The edge target fuel 
    is equivalent in all respects to the target fuel, except that no fuel 
    parameters are allowed to exceed the limits of the allowable range. In 
    effect, the edge target fuel represents the point in the multi-
    dimensional fuel parameter space where extrapolation begins.
    ---------------------------------------------------------------------------
    
        \9\ The allowable range of the model is, in fact, a combination 
    of the limits of the data and additional limitations that may be 
    imposed by the existence of extreme, or curve turnover points.
    ---------------------------------------------------------------------------
    
        The Complex Model equation for exhaust volatile organic compounds 
    (VOC) contained in Sec. 80.45(c)(1) includes a single interactive term. 
    This term, the product of E300 and aromatics, necessitates that 
    extrapolations involving E300 include a simultaneous evaluation of the 
    aromatics level of the target fuel. Thus in paragraph (c)(1)(iv)(C)(6), 
    Complex Model users are directed to determine whether the mathematical 
    phrase (80.32 + (-.390xARO)) is greater or less than 94, and to set the 
    E300 edge target fuel value accordingly. In so doing, users are 
    determining whether the aromatics-dependent E300 extrema (i.e. curve 
    turnover) point falls beyond the limits of the available data in the 
    Complex Model database.
        However, the language in paragraph (c)(1)(iv)(C)(6) is misleading. 
    As currently written, the user is directed to set the E300 value of the 
    edge target fuel at 94 vol% whenever the value of the phrase (80.32 + 
    (0.390xARO)) is greater than 94. The Agency's intention, however, was 
    that this step be taken only if the E300 term is being extrapolated. In 
    other words, if the target fuel value for E300 falls below the higher 
    limit for E300 in the allowable range as defined in Table 6, 
    Sec. 80.45(c)(1)(iv), then E300 is not being extrapolated, and the E300 
    value of the edge target fuel should be equal to the E300 value of the 
    target fuel.
        To correct this problem, the language in Sec. 80.45(c)(1)(iv)(C)(6) 
    and its counterpart applicable to Phase II calculations at Sec. 80.45 
    (c)(1)(iv)(D)(6) would be changed such that Complex Model users will 
    only set the E300 value of the edge target fuel equal to 94 if the 
    target fuel value for E300 exceeds the higher limit specified in Table 
    6, Sec. 80.45(c)(1)(iv).
    
    IV. RFG Compliance Requirements
    
    A. Sampling of Reformulated and Conventional Gasoline (Proposed 
    Sec. 80.47)
    
        Under Sec. 80.65(e)(1) refiners and importers are required to 
    collect a representative sample from each RFG batch produced or 
    imported, and to determine the batch properties based upon analysis of 
    this sample.10 ``Batch of reformulated gasoline'' is 
    currently defined in Sec. 80.2(gg) as ``a quantity of reformulated 
    gasoline which is homogeneous with regard to those properties which are 
    specified for reformulated gasoline certification.'' Similarly 
    Sec. 80.101(i)(1)(i)(A) requires refiners and importers of conventional 
    gasoline to collect a representative sample from each batch produced or 
    imported, and to determine compliance with the anti-dumping standards 
    based upon the batch samples.11
    ---------------------------------------------------------------------------
    
        \10\ Under Sec. 80.69(b) oxygenate blenders who meet the oxygen 
    standard on average also are required to sample and test each batch 
    of RFG produced using RBOB, and the discussion in this preamble 
    section applies to such oxygenate blenders in the same manner as for 
    refiners of RFG.
        \11\ EPA is proposing several changes relative to the sampling 
    of conventional gasoline that are discussed below in section VI.B. 
    of this preamble. EPA is also proposing to revise the ``batch'' 
    definition in Sec. 80.2(gg) to apply to conventional gasoline and 
    not just to RFG. EPA also is proposing to require refiners and 
    importers of conventional gasoline to separately test each batch, 
    which would eliminate the current option of testing a number of 
    batches together using a composite sample.
        In addition, EPA is proposing a definition for ``previously 
    certified gasoline'' to mean RFG and conventional gasoline for which 
    the refiner, oxygenate blender or importer has met applicable 
    requirements and standards and that the refiner, oxygenate blender 
    or importer has included or intends to include in the refinery or 
    importer compliance calculations.
    ---------------------------------------------------------------------------
    
        As a result, refiners and importers are required to collect a 
    representative sample of each gasoline batch. However, EPA has not 
    previously promulgated requirements for determining when a quantity of 
    gasoline is homogeneous so that it qualifies as a batch. Today EPA is 
    proposing such requirements for determining batch homogeneity. In 
    addition, EPA is proposing procedures whereby an importer of 
    reformulated or conventional gasoline would be able to treat as a 
    single batch the gasoline contained in multiple compartments of a ship.
        It is important that refiners and importers determine compliance 
    with the reformulated and conventional gasoline standards using samples 
    collected from quantities of gasoline that are homogeneous in terms of 
    the properties relative to these standards. If a quantity of gasoline 
    is not homogeneous, a sample of that gasoline often will not reflect 
    the overall average qualities of the gasoline. For example, when a 
    refiner produces gasoline by combining blendstocks having different 
    volatilities, unless the tank is thoroughly mixed the gasoline often 
    will be horizontally stratified, with the higher volatile blendstocks 
    at the top of the tank and the lower volatile blendstocks at the bottom 
    of the tank. If a sample is collected of the gasoline at any one spot 
    in such a stratified tank the sample only will reflect the properties 
    of the gasoline at that strata. Storage tank sampling techniques such 
    as ``all level samples'' or ``running samples'' tend to compensate for 
    stratified product, but these techniques do not assure a truly 
    representative sample.12
    ---------------------------------------------------------------------------
    
        \12\ A ``running sample'' of the product contained in a storage 
    tank is collected by lowering a sample container from the top of the 
    product to the bottom and then raising the container to the top, at 
    such a speed that the container is less than full when removed from 
    the tank. See, 40 CFR part 80, appendix D, para. 11.2.2.2. An ``all 
    levels sample'' is collected by lowering a stoppered container to 
    the bottom of the product in a storage tank, removing the stopper 
    with a cord or chain, and raising the container to the top at such a 
    speed that the container is less than full when removed from the 
    tank. See, 40 CFR part 80, Appendix D, para. 11.2.2.1. In theory, 
    both of these sampling methods obtain product from all strata in the 
    storage tank somewhat in proportion to the size of the strata.
    
    ---------------------------------------------------------------------------
    
    [[Page 37346]]
    
        In the case of RFG, moreover, certain standards must be met on a 
    per-gallon basis. If any portion of the RFG in a storage tank violates 
    an applicable per-gallon standard, this gasoline portion is out of 
    compliance even if the gasoline in the tank would be in compliance if 
    fully mixed. For example, consider a refinery storage tank containing 
    RFG designated as simple model, VOC controlled for Region 2. If the 
    gasoline is stratified by RVP, and the RVP of the upper strata is 
    greater than the applicable per-gallon maximum standard of 8.3 pounds 
    per square inch (psi),the gasoline in this upper strata would violate 
    the applicable per-gallon standard even if the average RVP of the 
    gasoline in the tank is less than 8.3 psi.13 A single sample 
    from such a stratified tank may not reflect the violation. Even an 
    ``all levels'' or ``running'' sample of the gasoline in a stratified 
    storage tank could yield a test result within the standard because to a 
    certain extent such a sample ``averages'' across the strata, which 
    would have the effect of masking the violation.
    ---------------------------------------------------------------------------
    
        \13\ Per-gallon standards must be met by all portions of the 
    gasoline contained in a storage tank in part because the different 
    gasoline portions may be distributed without further mixing.
    ---------------------------------------------------------------------------
    
        As a result, EPA is proposing that refiners and importers would be 
    required to establish that each quantity of reformulated or 
    conventional gasoline that will be treated as a batch is homogeneous 
    before the batch sample is prepared or analyzed.
        EPA is proposing two options by which the homogeneity of the 
    gasoline in a storage tank could be established. Under the first 
    option, a refiner would collect three separate samples from the storage 
    tank--upper, middle, and lower spot or tap samples. These samples would 
    be analyzed for each parameter relevant to applicable standards, and 
    the gasoline in the storage tank would be considered homogeneous if the 
    test results agree within the ranges specified in Sec. 80.65(e)(2)(i).
        Under the second option for establishing storage tank homogeneity, 
    the party would demonstrate that it followed tank mixing procedures 
    that can be shown to result in homogeneity. For example, a refiner 
    could meet the homogeneity requirement through records that show the 
    tank mixing procedures used for a batch (tank size and type, volume of 
    gasoline, the type of tank mixers, the mode of mixer operation if 
    appropriate, and the duration of mixer operation), together with 
    historic sampling and testing records demonstrate these procedures 
    result in complete mixing.
        Under this second storage tank option, success of the mixing 
    procedure must still be confirmed for each batch. However, instead of 
    requiring analysis for each parameter relevant to applicable standards, 
    only API gravity analysis of upper, middle, and lower spot or tap 
    samples would be required. The gasoline would be considered homogeneous 
    under this option if the demonstrated mixing procedure was performed, 
    and the API gravity values for the upper, middle, and lower samples do 
    not differ by more than 0.3 deg. API. Where the configuration of a 
    storage tank does not permit the collection of upper, middle, and lower 
    spot or tap samples, the API gravity analysis to confirm the success of 
    the mixing procedure would be waived.
        EPA also is proposing procedures whereby an importer would be able 
    to demonstrate the gasoline in multiple compartments of a marine vessel 
    is homogeneous. The importer would collect a ``running'' sample from 
    each compartment and analyze the samples for each parameter relevant to 
    applicable standards. The vessel's gasoline would be homogeneous and 
    could be treated as a batch if the results agree within the ranges 
    specified in Sec. 80.65(e)(2)(i).
        EPA is proposing that for purposes of establishing homogeneity a 
    party could use test methods other than the methods specified in 
    Sec. 80.46. The methods in Sec. 80.46 would still be used to establish 
    the batch properties for ``certifying'' a batch.
        EPA also is proposing that in the case of RFG, the gasoline 
    contained in a storage tank or marine vessel would not be considered 
    homogeneous if any sample collected to establish homogeneity has a test 
    result that exceeds an applicable per-gallon standard. Thus, in the 
    case of standards a refiner or importer is meeting on a per-gallon 
    basis no test result could violate the per-gallon standard, and in the 
    case of standards being met on average no test result could violate an 
    applicable per-gallon minimum or maximum standard.
        EPA is proposing additional options by which an importer could 
    treat the gasoline imported by marine vessel as a single batch without 
    determining the homogeneity of the gasoline. RFG contained in multiple 
    compartments of a marine vessel could be certified as a single batch 
    using a volume weighted composite of samples collected from the 
    compartments if the entire contents of these compartments is 
    transferred into a single shore tank. EPA is proposing this option 
    because it is likely the gasoline from multiple vessel compartments is 
    completely mixed, i.e., becomes homogeneous, through the process of 
    being transferred into a shore tank.
        Under today's proposal importers also would be allowed to use 
    composite samples to certify as a single batch the RFG imported by 
    marine vessel where the gasoline is off-loaded into multiple shore 
    storage tanks. Under this option, however, the importer would be 
    required to demonstrate that the RFG off-loaded into each shore tank 
    separately meets all applicable per-gallon standards, without regard to 
    any gasoline contained in the storage tank prior off-loading the 
    imported gasoline (or, ``heel''). Thus, the importer would be required 
    to sample and test the tank heel prior to off-loading the imported 
    gasoline and the tank contents after the imported gasoline has been 
    added, and to mathematically calculate the properties of the imported 
    gasoline added to the tank.
        EPA is proposing that imported conventional gasoline contained in 
    multiple compartments of a marine vessel could be tested using a volume 
    weighted composite of samples collected from the compartments with one 
    limitation. There are no per-gallon standards associated with 
    conventional gasoline (other than the complex model limit standards, as 
    is discussed in section III.A.1. of this Preamble), and, as a result, 
    there are no proposed requirements to separately test vessel 
    compartment or shore tanks. However, EPA is proposing that each 
    separate grade of conventional gasoline on a marine vessel (e.g., 
    regular, premium) must be treated as a separate batch. EPA believes 
    that, in general, there is greater variability in the properties of 
    gasolines of different grades, than of gasolines of the same grade. The 
    proposed grade limitation on marine vessel compositing for conventional 
    gasoline would constitute some limit on the range of gasoline 
    properties that could be included in a single composite sample, which 
    EPA believes would improve the quality of composite samples. EPA 
    requests comment on this proposed limitation on the use of composite 
    samples of imported conventional gasoline.
    
    C. General Requirements (Sec. 80.65)
    
    1. Assignment of Batch Numbers (Sec. 80.65(d)(3))
        Section 80.65(d)(3) requires refiners and importers to assign batch 
    numbers to batches of RFG, RBOB, conventional gasoline, and certain 
    blendstock that is included in the refiner's compliance
    
    [[Page 37347]]
    
    calculations. The batch numbers are used to identify batches in batch 
    reports submitted to EPA under Secs. 80.75(a) and 80.105(a).
        EPA is proposing to revise Sec. 80.65(d)(3) to require oxygenate 
    blenders who meet the oxygen standard on average to assign batch 
    numbers to RFG batches. This would conform Sec. 80.65(d)(3) with the 
    current reporting requirement at Sec. 80.74(a), that oxygenate blenders 
    who meet the oxygen standard on average must submit batch reports to 
    EPA.
    2. Clarifications of Requirement to Test RFG and RBOB 
    (Sec. 80.65(e)(1))
        Section 80.65(e)(1) requires refiners and importers to determine 
    the properties of each batch of RFG that is produced or imported. 
    Gasoline that complies with the standards in Sec. 80.41 is deemed 
    certified (Sec. 80.40(a)), hence this process is commonly considered as 
    ``certifying'' each batch. This determination is required for each 
    parameter relevant to the RFG standards. EPA is proposing two 
    clarifications of Sec. 80.65(e).
        EPA is proposing to add language to Sec. 80.65(e) to clarify that 
    this section applies to RBOB as well as to RFG, and to add a cross 
    reference to the requirement in Sec. 80.69(a)(2) that the certified 
    properties of RBOB are the properties of the RBOB subsequent to 
    downstream blending with oxygenate, based on test results of a sample 
    of the RBOB hand blended in the laboratory with the appropriate 
    oxygenate type and amount. EPA believes the certification of RBOB 
    already is implicit in Sec. 80.65(e), and that refiners and importers 
    have been certifying and reporting the properties of RBOB based on the 
    analysis results of a hand blend, so that the proposed changes would 
    not change current practices.
        EPA also is proposing to clarify that certification testing for RVP 
    is necessary only for RFG and RBOB that is designated as VOC 
    controlled, because RVP test results are relevant only to VOC 
    controlled gasoline. Under the simple model the RVP standard applies 
    only to VOC controlled product. RVP test results are an input to the 
    complex model only for VOC controlled gasoline; in the case of non-VOC 
    controlled gasoline the complex model uses an RVP value of 8.7 psi 
    regardless of the actual RVP value of the gasoline. This change to 
    Sec. 80.65(e) also would change the reporting requirement for RVP, to 
    apply only to VOC controlled RFG and RBOB, because the parameter 
    reporting requirement in Sec. 80.75(a)(2)(v)(B) cross references the 
    requirements in Sec. 80.65.
    3. Weight Percent Range for Total Oxygen Content (Sec. 80.65(e)(2)(i))
        Section 80.65(e)(2)(i) provides a table with ranges for fuel 
    properties to be used in comparing the refiner's or importer's test 
    results to the test results obtained from the independent laboratory. 
    The table at Sec. 80.65(e), however, currently does not include a range 
    for total oxygen content. The RFG regulations prescribe a standard for 
    weight percent oxygen, and refiners and importers of RFG are required 
    to determine and report the total weight percent of oxygen in each 
    batch of RFG for compliance purposes. It is appropriate, therefore, to 
    include a range for total oxygen content in the table at Sec. 80.65(e) 
    for purposes of comparing the refiner's or importer's test results with 
    the test results obtained from the independent laboratory. A range for 
    total weight percent oxygen content was unintentionally omitted in the 
    final rule. As a result, today's rule proposes to add to the table at 
    Sec. 80.65(e)(2)(i) a 0.10 wt% range for total oxygen content. This 
    range would be in addition to, and not instead of, the volume ranges 
    for oxygenates listed in Sec. 80.65(e)(2)(i).
        The 0.10 wt % range for total oxygen was derived by multiplying the 
    values of the oxygenates in the table in Sec. 80.65(e)(2)(i) by the 
    weight % of the oxygen in the oxygenates and averaging them. EPA 
    acknowledges that this approach assumes that the density of these 
    oxygenates is similar to gasoline, but believes that any difference in 
    density would result in an insignificant increase in the 0.10 wt % 
    value. EPA continues to believe that this is an appropriate method of 
    determining an appropriate range for total oxygen content between the 
    refiner's laboratory and the independent laboratory.
        4. Independent Laboratory Requirements (Sec. 80.65(f); Proposed 
    Secs. 80.72, 80.74(h), and 80.75(n))
        Sections 80.65(e) and (f) contain the independent laboratory 
    requirements for RFG. Under Sec. 80.65(e)(1) each batch of RFG must be 
    analyzed, either by the refiner or importer, or by an independent lab. 
    Section 80.65(f) requires each refiner and importer of RFG to designate 
    an independent lab that must collect a sample from each batch of RFG. 
    The refiner/importer then has the option of having the independent lab 
    meet the analysis requirement for all RFG batches (the 100% analysis 
    option), or of having the independent lab analyze up to 10% of the 
    samples collected to be identified by EPA (the 10% analysis option). 
    The 100% analysis option is most often chosen by importers who do not 
    operate their own company laboratory.
        EPA is proposing two categories of changes to the independent 
    laboratory requirements. The first category of changes would include in 
    the regulations the guidance EPA previously has issued regarding the 
    identification of samples for analysis by independent labs, and the 
    identification of samples the independent lab would send to EPA. The 
    second category would slightly narrow the criteria by which a 
    laboratory is considered independent. In addition, EPA is seeking 
    comment on whether companies that serve as independent laboratories 
    under the RFG program should be made directly responsible for properly 
    completing the functions of sample collection, analysis, record keeping 
    and reporting.
        The first category of changes being proposed relate to the 
    identification of samples to be analyzed under the 10% analysis option, 
    and the identification of samples to be supplied to EPA under both the 
    10% and the 100% analysis options.
        Sections 80.65(f)(1)(ii) (B) and (C) state that under the 10% 
    independent analysis option, EPA will identify which samples the 
    independent lab must analyze. However, the regulations do not specify 
    the mechanism by which EPA identifies these specific samples. EPA 
    subsequently provided this sample-identification guidance in 
    Reformulated Gasoline and Anti-Dumping Questions and Answers (October 
    3, 1994), titled ``Reformulated gasoline program protocol for use by 
    independent labs in selecting samples for analysis under the 10% 
    independent analysis option, and for identifying samples to ship to 
    EPA.'' This protocol has been in use since it was issued, and EPA has 
    received no adverse comments from regulated parties regarding this 
    protocol. Therefore, EPA proposes to incorporate this protocol in the 
    RFG regulations. See proposed Sec. 80.72.
        EPA believes the protocol is an appropriate mechanism for 
    identifying samples for analysis by independent labs. The protocol 
    provides an automated system to randomly identify for analysis 10% of 
    the samples collected by an independent lab in a way that gives 
    regulated parties no influence over the sample choice.
        In addition to identifying the independent laboratory samples to be 
    analyzed, the proposed protocol also identifies which samples must be 
    supplied to EPA, including the minimum sample quantity to supply. The 
    requirement to forward samples to EPA applies to both the 10% and the
    
    [[Page 37348]]
    
    100% analysis options, and, therefore, the proposed sample-shipment 
    protocol applies to both options. Further, the regulations would 
    instruct independent labs to send to EPA any sample that, when tested 
    by the independent lab, is found to violate a per-gallon standard that 
    applies to the refiner or importer.
        The proposal also would specify the quantity of gasoline that 
    independent labs would be required to supply to EPA. The batch sampling 
    methodologies of appendix D, in section 12.2, call for sample 
    containers of one quart as a minimum. Assuming that a single sample is 
    collected in a one quart container and that the container is filled 
    only to the minimum 70% level (appendix D requires samples to be 70-85% 
    full), this would provide a total of approximately 660mL of gasoline. 
    EPA believes one-half of this quantity, or 330mL, is sufficient for a 
    laboratory to complete all the testing requirements of the RFG 
    regulations. Therefore, where an independent lab analyzes an RFG sample 
    that also must be supplied to EPA, at least half the original sample 
    volume, or 330mL, would be available for shipment to EPA. Under the 
    proposed regulation regarding sample quantity, where the independent 
    lab has not analyzed a sample the lab would be required to supply EPA 
    with a one quart sample 70-85% full. In the case of a sample that has 
    been analyzed by the independent laboratory the lab would be required 
    to supply EPA with a minimum sample volume of 330mL.
        The proposed regulations state that samples supplied to EPA should 
    be sent to an address to be specified by EPA. This address would be the 
    following: United States Environmental Protection Agency, National 
    Vehicle and Fuel Emissions Laboratory (NVFEL), Fuels and Chemical 
    Analysis Branch 2565 Plymouth Road, Ann Arbor, MI 48105, (313) 668-
    4200.
        EPA is not proposing to include this address in the regulations in 
    order to facilitate an address change if it becomes necessary. If there 
    is an address change for samples shipped to EPA, regulated parties 
    would be notified through individual letters, a Federal Register 
    notice, or some other appropriate means.
        The second change being proposed would revise one criteria used to 
    determine if a laboratory is ``independent.'' Section 
    80.65(f)(2)(iii)(A), and proposed Sec. 80.72(b)(2)(I), specify that in 
    order to be considered independent a laboratory may ``not be operated 
    by any refiner or importer * * *.'' EPA now believes this independence 
    requirement is too stringent, and should apply only in the case of 
    refiners and importers of RFG.
        Laboratories used to satisfy the independent sampling and testing 
    requirements are required to be independent in order to increase the 
    credibility of the laboratories' test results, as discussed at 59 FR 
    7765 (February 16, 1994). The independent sampling and testing 
    requirement applies only to refiners and importers of RFG, however, and 
    as a result EPA believes refiners and importers who operate a 
    commercial laboratory, but who produce or import no RFG, should be 
    allowed to serve as independent laboratories under the RFG program. EPA 
    is proposing that this definition of ``independence'' would not apply 
    if any RFG is produced or imported within a common corporate structure. 
    Thus, if a parent corporation has a subsidiary corporation that is a 
    refiner or importer of RFG, no other subsidiary of that parent 
    corporation could be considered independent.
        Finally, EPA is seeking comment on whether companies that serve as 
    independent laboratories should be made regulated parties under the RFG 
    program.
        Section 80.65(f)(3) describes the sample collection and reporting 
    procedures, and requires that each refiner or importer shall ``cause 
    its designated independent laboratory'' to carry out these procedures. 
    Under these procedures the independent lab collects a representative 
    sample from the RFG batch, determines the batch volume and other 
    information about the batch, reports test results to EPA, and supplies 
    samples to EPA upon request. A refiner or importer whose independent 
    lab fails to properly carry out these procedures would have failed to 
    meet the independent lab requirements, which would constitute a 
    violation of the RFG requirements by the refiner or importer.
        EPA requests comments on whether the regulations should be revised 
    to provide that a laboratory that undertakes to act as an independent 
    lab under the RFG program becomes responsible to properly carry out the 
    independent lab requirements, in order to allow better monitoring and 
    enforcement of the independent lab requirements. For example, currently 
    there is no requirement for independent labs to retain records, which 
    creates potential difficulties when EPA attempts to audit and inspect 
    independent labs.
        Under this approach, where an independent lab failed to properly 
    carry out an independent lab procedure, the independent lab would be 
    liable for a violation of the RFG regulations. In addition, the refiner 
    or importer for whom the lab is performing the independent lab function 
    would have failed to meet the independent lab requirement which would 
    constitute a violation of the RFG regulations. Under this approach, the 
    independent lab would also be required to retain records and submit 
    reports to EPA.
        The authority to regulate laboratories that serve as an independent 
    labs under the RFG program is based on Clean Air Act sections 114(a), 
    208(a), 211(c), and 211(k). Analysis of RFG by independent laboratories 
    is critical to enforcement of the RFG standards, for reasons that are 
    discussed at 59 FR 7765 (February 16, 1994). In order for independent 
    laboratory sampling and testing to serve a useful purpose, however, the 
    independent lab must properly perform the procedures. EPA believes 
    independent labs would be more likely to take the steps necessary to 
    ensure the required procedures are properly performed if there were 
    regulatory consequences that applied directly to the independent 
    laboratory, and not just indirectly through sanctions against the 
    refiner or importer.
        The current regulations state that a lab that is debarred, 
    suspended, or proposed for debarment pursuant to the Governmentwide 
    Debarment and Suspension regulations cannot serve as an independent lab 
    under the RFG program. An independent lab that fails to properly carry 
    out the required procedures could be the subject of a suspension or 
    debarment action by EPA. EPA requests comment on whether the suspension 
    or debarment sanction is adequate to ensure that independent labs 
    properly perform required procedures, in the absence of regulatory 
    liability.
        In addition, EPA requests comment on whether regulations should be 
    proposed that would require labs to be accredited in order to carry out 
    the RFG independent lab requirements. EPA has not previously proposed a 
    lab accreditation requirement because of the likelihood that refiners 
    and importers would use only labs the refiners and importers are 
    convinced are fully capable of properly performing the independent lab 
    requirements. However, EPA has received comments that an accreditation 
    requirement could result in greater certainty that labs have the 
    equipment, training, and internal procedures necessary to properly 
    carry out the independent lab requirements, that could assist refiners 
    and importers in selecting independent labs.
        Therefore, EPA requests comments on whether lab accreditation would 
    be appropriate for the RFG program;
    
    [[Page 37349]]
    
    whether accreditation should be performed by EPA or by an independent 
    body, and which independent body or bodies should be considered; the 
    accreditation criteria that would be appropriate; the estimated costs 
    of an accreditation program; and any other considerations EPA should 
    include as part of a lab accreditation proposal.
    5. Compliance Audits (Sec. 80.65(h) and Sec. 80.105(c))
        EPA proposes to modify Secs. 80.65(h) and 80.105(c) to make clear 
    that the attest requirement applies separately to each refinery 
    operated by a refiner, or the gasoline imported by an importer. The 
    amended rules clarify EPA's intent that refiners and importers of RFG, 
    RBOB, and conventional gasoline, and oxygenate blenders who blend RBOB 
    and meet the oxygen standard on average, must perform a separate attest 
    engagement for each facility at which such gasoline or product is 
    produced. In the process of issuing the Final Rule, EPA considered and 
    rejected the suggestion that parties be able to aggregate multiple 
    facilities within one attest engagement. Such an aggregation would 
    adversely skew the effect of the random sampling protocol described in 
    Sec. 80.127 by increasing the population of batches subject to random 
    sampling, and by potentially spreading the samples drawn over several 
    facilities. The effect, therefore, would be to produce less than the 
    95% confidence level for each facility that the attest engagement is 
    designed to accomplish.
    6. Calculations Involving Previously Certified Gasoline (Sec. 80.65(i); 
    Sec. 80.78(a); Sec. 80.101(e))
        Under Secs. 80.65(i) and 80.101(e)(1) refiners are required to 
    exclude from a refinery's compliance calculations gasoline that was not 
    produced at that refinery and gasoline that was produced at that 
    refinery but was included as part of another batch, sometimes called 
    ``previously certified gasoline,'' or ``PCG.'' These requirements are 
    included in order to prevent double counting of PCG. Section 
    80.101(g)(3) provides the procedure by which refiners are required to 
    calculate the properties of blendstock that are combined with PCG to 
    produce conventional gasoline. However, the procedure in 
    Sec. 80.101(g)(3) is appropriate only for the simple model anti-dumping 
    standards, and there is no procedure specified for excluding PCG from 
    RFG compliance calculations. As a result, EPA is proposing procedures 
    for excluding PCG from the complex model compliance calculations for 
    both RFG and conventional gasoline. In addition, the procedures EPA is 
    proposing would allow refiners to use conventional gasoline to produce 
    RFG or RBOB, and to reclassify RFG with regard to VOC control and OPRG.
        The procedures EPA is proposing would require refiners to determine 
    the volume and properties of each batch of PCG used in the refinery 
    operation, along with the designations of the gasoline: RFG, RBOB or 
    conventional gasoline; and for RFG, the designations relative to VOC 
    control and OPRG. The volume and properties of each PCG batch would be 
    reported to EPA as a negative batch using the same designations as when 
    received by the refiner. The PCG then would be used by the refiner as 
    another blendstock in the refinery operation, and any gasoline produced 
    using the PCG would be sampled and tested and included in compliance 
    calculations without regard to the PCG content. Gasoline produced using 
    the PCG could have the same designations as the original PCG batch, or 
    different designations. Thus, the proposed procedures would allow a 
    refiner to reclassify conventional gasoline as RFG, or to reclassify 
    RFG with regard to VOC control and OPRG.
        Under the current regulations refiners are prohibited from 
    reclassifying gasoline in certain ways. For example, Sec. 80.78(a)(10) 
    prohibits any person from reclassifying conventional gasoline as RFG. 
    However, EPA understands that prohibitions against reclassifying 
    gasoline, such as Sec. 80.78(a)(1), constrain the operational 
    flexibility for regulated parties, and that such prohibitions should be 
    imposed only where necessary. EPA believes the PCG proposal allows 
    greater flexibility without compromising the environmental goals or 
    effective enforcement of the RFG program, and the PCG proposal is 
    appropriate for this reason.
        In the case of standards that are met on average a refiner who uses 
    PCG would meet each average standard based upon the net average 
    properties of gasoline in the relevant averaging pool, 14 
    consisting of the positive volume and properties of all gasoline 
    produced in that averaging pool and the negative volume and properties 
    of all PCG in that averaging pool. In addition, each averaging pool 
    would be required to have a net ``positive'' gasoline volume--each 
    averaging pool's volume of gasoline produced would have to be greater 
    than the volume of PCG.
    ---------------------------------------------------------------------------
    
        \14\  Compliance with each average standard is based on the 
    average property or emissions performance of the subset of the 
    gasoline produced at a refinery that is relevant to that standard, 
    sometimes called an ``averaging pool.'' For example, the averaging 
    pool for anti-dumping standards is all conventional gasoline 
    produced during an averaging period. In addition, certain RFG 
    standards must be separately met by more than one averaging pool. 
    For example, under Sec. 80.67(g) the RFG NOx emissions performance 
    standard must be met by the averaging pool of all RFG and RBOB that 
    is VOC controlled, and separately by the averaging pool of all RFG 
    and RBOB that is not VOC controlled.
    ---------------------------------------------------------------------------
    
        Consider, for example, Refiner A who has elected to meet the VOC 
    emissions performance standard on average at Refinery X. In this 
    example a batch of PCG, designated as RFG, VOC controlled for Region 1, 
    is used to produce RFG at Refinery X. This PCG would be included as a 
    negative batch in Refinery X's VOC emissions performance compliance 
    calculations for the ``VOC controlled for Region 1'' averaging pool, 
    regardless of whether the PCG was used to produce RFG with this or with 
    another designation. 15 Refiner A nevertheless would be 
    required to meet the VOC standard for the ``VOC controlled for Region 
    1'' averaging pool, and the net volume of gasoline in this averaging 
    pool would have to be greater than zero.
    ---------------------------------------------------------------------------
    
        \15\  EPA is proposing that a ``negative'' batch would be 
    included in the ``Actual Total'' calculation in Sec. 80.67(g)(1)(ii) 
    by multiplying the ``Vi'' term (the batch volume) times 
    minus 1.
    ---------------------------------------------------------------------------
    
        In a case where a refiner has elected to meet a parameter or 
    emissions performance standard on a per-gallon basis, and a batch of 
    RFG or RBOB is produced using previously certified RFG, the value of 
    the per-gallon standard the refiner would be required to meet for this 
    batch would be the more stringent of: (1) The per-gallon standard that 
    applies to the refinery under Sec. 80.41; or (2) the value for that 
    parameter or emissions performance for the previously certified RFG 
    used to produce the batch. If previously certified conventional 
    gasoline is used, however, use of this PCG would not affect the per-
    gallon RFG standards.
        Consider again the example of Refiner A, and in this example 
    Refiner A has elected to meet the benzene standard on a per-gallon 
    basis at Refinery X. Under Sec. 80.41(c), and in the absence of 
    applicable survey ratchets, the benzene per-gallon standard is 1.00 
    volume percent (vol%). Also, in this example the batch of previously 
    certified RFG has a benzene content of 0.85 vol%. In consequence, any 
    RFG produced at Refinery X using any amount of this PCG would be 
    subject to a benzene per gallon standard of the more stringent 0.85 
    vol%.
        Any previously certified conventional gasoline used to produce RFG 
    or conventional gasoline would be included in the compliance 
    calculations
    
    [[Page 37350]]
    
    for the gasoline produced. In addition, the previously certified 
    conventional gasoline would be included, as a negative batch, in the 
    refinery's anti-dumping compliance calculations.
        Finally, any previously certified RFG or conventional gasoline 
    would be included as a negative volume for purposes of calculating a 
    refinery's compliance baseline under Sec. 80.101(f).
        The proposed approach is summarized in the following table.

        EPA believes the approach proposed for addressing PCG is 
    appropriate because it would provide regulated parties with 
    significantly additional flexibility, with no apparent risk of adverse 
    environmental consequences. The additional flexibility would result 
    from the ability for regulated parties to more easily use previously 
    certified gasoline in refinery operations.
        At the time the RFG regulations were promulgated EPA was concerned 
    that the overall quality of the various gasoline pools could be 
    degraded if refiners were able to reclassify conventional gasoline into 
    RFG, or to reclassify certain categories of RFG into other categories. 
    For example, if a refiner could reclassify conventional into RFG, it 
    would be possible for a refiner to produce very ``clean'' conventional 
    gasoline and include this gasoline in its anti-dumping compliance 
    calculations, and then reclassify this same gasoline into RFG with very 
    little or no additional blending. This would enable the refiner to meet 
    the anti-dumping standards using gasoline that, in reality, will be 
    used as RFG. One effect of this type of ``gaming'' would be to degrade 
    the quality of the conventional gasoline pool, with consequent adverse 
    environmental effects.
        As a result of these concerns, EPA included provisions in 
    Sec. 80.78 that prohibit parties from combining certain categories of 
    gasoline. For example, Sec. 80.78(a)(10) prohibits parties from 
    combining RFG with conventional gasoline to produce RFG, in part in 
    order to address the ``gaming'' concern described above.
        However, the proposed PCG accounting procedure would allow refiners 
    to reclassify conventional gasoline into RFG in a manner that avoids 
    the potential for adverse environmental effects from ``gaming.'' This 
    is true because reclassifications using PCG may occur only at a 
    refinery, and the PCG must be included, as a negative batch, in the 
    refinery's compliance calculations for the gasoline pool that 
    corresponds to the PCG's designations when first produced. Consider 
    again the example of ``gaming'' involving very ``clean'' conventional 
    gasoline, described above. Under the PCG proposal any of the very 
    ``clean'' conventional gasoline used as PCG would have to be included 
    in the refinery's anti-dumping compliance calculations as a negative 
    batch, this pool would have to meet the anti-dumping standards, and the 
    pool volume would have to be positive. This would require the refiner, 
    in effect, to produce other conventional gasoline that is equal in 
    quantity and quality to very ``clean'' conventional gasoline used as 
    PCG, that would offset the loss of this gasoline to the conventional 
    gasoline pool. Thus, under the proposal there would be no net change in 
    the quality of the conventional gasoline pool.
        This same logic would allow refiners to reclassify RFG with regard 
    to VOC control and OPRG.
        In the case of RFG standards that are met on a per-gallon basis, a 
    different approach would be used to ensure no degradation in the 
    quality of the overall RFG pool as a result of the PCG proposal, since 
    averaging calculations are performed only where standards are met on 
    average. The approach proposed, as discussed above, would prohibit the 
    receiving refiner from degrading the quality of any previously 
    certified RFG batch with regard to any standard the receiving refiner 
    meets on a per-gallon basis, by setting the per-gallon standard at the 
    parameter value of the PCG if it is more stringent than the normal per-
    gallon standard.
        As a result, EPA is proposing to specifically allow refiners to 
    change the classifications of RFG and conventional gasoline under the 
    PCG procedures. In addition, EPA is proposing to revise the 
    prohibitions in Sec. 80.78 to reflect the PCG proposal. In proposed 
    revisions to Secs. 80.78(a) (5) and (7) parties would be allowed to 
    combine RFG or RBOB with blendstock under the terms of the PCG 
    proposal.
        Under the proposed PCG procedures it would be important that any 
    gasoline claimed as PCG actually is used in a refinery's operation--
    otherwise, these procedures could cause a degradation in gasoline 
    quality. For example, consider a refinery that received a batch of 
    relatively ``dirty'' conventional gasoline. If this gasoline is 
    classified as PCG, is used in the production and compliance 
    calculations of conventional gasoline, and is added to the anti-dumping 
    compliance calculations as a negative batch, there would be no net 
    effect of the ``dirty'' PCG on the refinery's overall anti-dumping 
    compliance calculations. If, however, the refiner never used the PCG as 
    a component for gasoline production, yet included the ``dirty'' PCG as 
    a negative batch in compliance calculations, the refinery's 
    conventional gasoline pool would appear ``cleaner'' than it was in 
    reality.
        As a result, EPA is proposing record keeping and attest 
    requirements that would apply in the case of any refiner who uses the 
    PCG option, that would include records demonstrating the storage and 
    movement of the PCG from the time it is received at the refinery until 
    it is used in the production of gasoline. The proposed attest 
    procedures would require the auditor to verify that PCG was used to 
    produce gasoline at the refinery, and that the PCG batch report to EPA 
    is consistent with the refiner's sampling and testing of the PCG, and 
    the PCG product transfer documents, when received at the refinery.

    7. Requirements for Imported Gasoline (Sec. 80.65(j))
        Section 80.65(j) ``Requirements for imported gasoline,'' is 
    proposed as an addition to the general requirements of Sec. 80.65(e) to 
    qualify import certifications. This is in response to importer and 
    independent laboratory questions regarding certification of import 
    cargoes. The Agency has received questions regarding where and when 
    imported gasoline must be certified, and how to treat gasoline destined 
    for multiple ports. The Agency has issued policy guidance in response 
    to these questions in Reformulated Gasoline and Anti-Dumping Questions 
    and Answers. Today's regulatory revision is somewhat more restrictive 
    than the Reformulated Gasoline and Anti-Dumping Questions and Answers 
    policy guidance, in that batch certification would have to comply with 
    the U.S. Customs Service requirements for imported gasoline. The 
    original intent of the RFG regulation was to follow the normal import 
    industry practices as regulated by the U.S. Customs Service. Some 
    allowances were provided in the Reformulated Gasoline and Anti-Dumping 
    Questions and Answers guidance that may not conform with the U.S. 
    Customs Service regulations and today's proposal reverses any changes 
    that may have occurred.
        The first requirement proposed in Sec. 80.65(j) is that batch 
    certification sampling be conducted at the time and place permitted 
    under U.S. Customs Service regulations, 19 CFR 151.42, and as specified 
    in the new Sec. 80.47 Sampling of reformulated and conventional 
    gasoline, which is discussed above. Section 80.47 provides specific 
    sampling procedures for reformulated and conventional gasoline, and 
    refers to Sec. 80.8 Sampling Methods for the general sampling 
    procedures that apply.
        This requirement reflects the majority of guidance provided in 
    Reformulated Gasoline and Anti-Dumping Questions and Answers. For 
    instance, the guidance provides that when an import vessel off-loads 
    its cargo at more than one U.S. Customs Service port, then it must 
    certify the cargoes off-loaded in the separate ports as different 
    batches. The reason for this is that there is no mechanism for EPA to 
    enforce or even to find out about possible additions to a certified 
    batch when a vessel leaves the port where it was sampled. Today's 
    proposal also requires separate batch certifications for separate entry 
    ports as governed by the U.S. Customs Service regulations. However, in 
    Reformulated Gasoline and Anti-Dumping Questions and Answers, an 
    exception to this guidance is provided for multiple ports within a 
    given harbor area, such as the New York City harbor area, wherein a 
    single batch may be off-loaded at multiple Customs ports within the 
    harbor. Today's proposal will not include this exception because it 
    does not conform with U.S. Customs Service regulations. EPA relies on 
    U.S. Customs Service records for enforcement of the EPA fuels 
    regulations. By following the Customs Service regulations EPA maximizes 
    the usefulness of this enforcement tool. It also minimizes regulatory 
    confusion by conforming the EPA requirements with an existing 
    regulatory requirement of the U.S. Customs Service.
        U.S. Customs Service regulations for imported petroleum products 
    allow for sampling once an import vessel is docked and ready to off-
    load its cargo, although under 19 CFR 151.42, Controls on unlading and 
    gauging, each port director independently establishes the methods of 
    control. As such, the protocols for sampling an import vessel could 
    vary from port to port and could also depend on the type of import 
    vessel (for instance, ship, barge, rail car). EPA requests comments on 
    the requirement to follow the U.S. Customs Service procedures during 
    batch certification. EPA will retract any conflicting guidance that 
    remains in Reformulated Gasoline and Anti-Dumping Questions and Answers 
    after final revisions to this regulation are promulgated.
        The second and final requirement of proposed Sec. 80.65(j) is that 
    batch size could be no larger than a ``line item,'' or a single item of 
    merchandise, of an entry summary under U.S. Customs Service 
    requirements specified at 19 CFR part 141, subparts D, E, and F, and 
    part 142, subparts A and B. These subparts of the Customs Service 
    regulations specify the documentation required for import cargoes. This 
    documentation must differentiate merchandise by listing or invoicing 
    items subject to different duty rates (19 CFR 141.61(e)), and it must 
    list or invoice items of varying commercial value separately (19 CFR 
    141.86). Therefore, it is EPA's understanding that the Customs Service 
    regulations require quantities of gasoline imported on a single vessel 
    to be distinguished on the basis of their differences in commercial 
    values or potential for differences in commercial value. For instance, 
    different grades (segregated in different tanks) would be entered as 
    separate line items. Also, gasoline from different sources but of the 
    same grade, would normally be entered as separate line items due to 
    their potential for the separate sources not meeting the agreed upon 
    commercial specifications. Limiting batch size to U.S. Customs Service 
    entry ``items'' serves two functions: (1) It adjusts the EPA 
    requirements to fit better with the existing regulatory standards of 
    the U.S. Customs Service, and (2) it puts a limit on the variations of 
    RFG property values within a batch (that could lead to inaccurate 
    sample representation as discussed above in the preamble to Sec. 80.47, 
    regarding homogeneity determination).
    
    D. Compliance on Average (Sec. 80.67)
    
    1. Transfer of Oxygen and Benzene Credits (Sec. 80.67(h)(1)(iv))
        Section 80.67(h)(1)(iv) permits the transfer of credits directly 
    from the refiner, importer, or blender who generates them to the 
    refiner, importer, or blender who uses the credits for compliance 
    purposes. EPA has received several inquiries with regard to whether 
    transfers within the same company are included in the language of this 
    section. It is the Agency's intention that the refiner, importer, or 
    blender may properly transfer legitimate credits within the company or 
    outside of the company. As a result, EPA is proposing to modify 
    Sec. 80.67(h)(1)(iv) to clarify that credit transfers may be either 
    intercompany or intracompany.
    
    E. Compliance Survey Requirements (Sec. 80.68)
    
    1. Method of Computation for Averages in Survey Series (Secs. 80.68 
    (c)(9)(I)(B) and (ii)(B), (c)(10), (c)(11), (c)(12) and (c)(13))
        The RFG surveys were designed to deter and detect situations where 
    the flexibility afforded refiners through averaging gasoline 
    characteristics at the refinery gate (as opposed to averaging each 
    refinery's contribution to the gasoline in a particular covered area) 
    results in a covered area obtaining gasoline that on average differs in 
    relevant qualities from the average gasoline quality that would occur 
    if averaging was required separately for each covered area. The surveys 
    are conducted by an industry association according to a statistical 
    sampling plan approved by EPA and involve sampling gasoline from retail 
    outlets. If the gasoline in an area fails to meet standards set forth 
    in the regulations for a particular parameter, the standards for that 
    parameter are made more stringent and the number of surveys that must 
    be conducted in the following year is increased.
    
    [[Page 37352]]
    
        Some of the gasoline characteristics evaluated by the survey are 
    chiefly of interest because of their role in causing or contributing to 
    ambient ozone levels. Surveys for these parameters (e.g., VOC surveys) 
    are passed or failed based upon the average of results from a week-long 
    survey. Other parameters (like benzene and toxics) are of concern 
    because of their cumulative effects over a longer period of time. 
    Surveys for these latter characteristics are passed or failed based 
    upon the average of a year-long series of one-week surveys. This 
    discussion is primarily concerned with how the average of such a series 
    of one-week surveys should be computed.
        Under the current regulations, determining the average for each 
    survey series 16 involves computation of a simple average 
    17 of parameter values from each gasoline sample across all 
    of the samples gathered during the year (without any consideration of 
    which week-long survey the sample was a part). If all of the individual 
    week-long surveys had equal sample sizes, this approach to computation 
    would yield as good a representation of the fuel supply as the timing 
    and distribution of the week-long surveys throughout the year 
    permitted.18 Practical considerations involved in the design 
    and conduct of an efficient overall survey operation, though, dictate 
    some substantial variations in sample size among the week-long surveys. 
    One such effect, and probably the most important one, stems from the 
    fact that high-ozone season surveys for ozone precursors must yield a 
    confidence interval on the mean small enough to meet the precision 
    requirements of the regulations (Sec. 80.68(c)(13)(iii)) for each 
    individual survey. Since practical considerations dictate that surveys 
    for the various parameters be conducted concurrently (i.e., each 
    gasoline sample is analyzed for all parameters covered by the survey 
    program), this situation results in larger-than-necessary sample sizes 
    in the summer for non-ozone precursor parameters. Outside the summer 
    ozone season there is no need to maintain precision standards for each 
    individual survey, but only for the annual series of such surveys. In 
    the interest of efficiency, the survey manager may be expected to cut 
    back on sample sizes during these times at the beginning and end of the 
    calendar year. As a result, the simple average substantially 
    overrepresents summertime gasoline.
    ---------------------------------------------------------------------------
    
        \16\ Sec. 80.68(c)(9)(i)(B) for toxics; (10)(ii) for 
    NOX; (11) for benzene; and (12) for oxygen.
        \17\ In the case of toxics, the computation introduces weights 
    for the season (high-ozone season or outside of high-ozone season) 
    since the statistical model used to compute the emissions is 
    different in the two seasons. The weights substantially correct the 
    overemphasis on summer that affects other non-ozone-related 
    parameters, as discussed in the remainder of the text.
        \18\ While the design for each of the individual week-long 
    surveys is probabilistic, a variety of considerations prevent EPA 
    from distributing the surveys in a perfectly random manner with 
    respect to time. The overall sampling approach for survey series 
    thus departs, to some extent, from a purely probabilistic design.
    ---------------------------------------------------------------------------
    
        An additional reason for altering the prescribed approach to 
    computing averages of series has to do with the weights attached to 
    each sample to handle either lack of pre-survey information about an 
    individual retail outlet's throughput or the situation where an outlet 
    with unusually high throughput is located in a covered area with 
    relatively few outlets and is consequently selected into the sample 
    with certainty. For both situations the sample is not self-weighting 
    and weights must be computed to properly represent the outlet's 
    gallonage in the sample. The current approach, the simple average, 
    requires that such weights be computed two different ways, once for the 
    outlet's inclusion in the week-long survey for ozone-related parameters 
    and then again for the annual average computation for non-ozone-related 
    parameters. The latter set of weights cannot be computed until the 
    year's data collection is complete, leaving some uncertainty up to the 
    end of the year as to the status of survey results in areas where 
    throughput data are not available for most outlets. This particular 
    problem is a characteristic of the sample design approach currently 
    being used by the industry survey organization, but that approach or 
    some variant of it is likely to be used in any thorough attempt to meet 
    the survey requirements in the regulations.
        Both the distortion and the difficulty in computing weights, as 
    discussed above, can be eliminated by changing the method by which the 
    average of each survey series is computed for a given parameter in a 
    given RFG covered area. Instead of averaging all of the measurements on 
    individual gasoline samples in the survey series, we are proposing the 
    following: (1) That the measurements for each week-long survey in an 
    area be averaged, regardless of the sample size, to create a set of 
    means of week-long surveys, and then (2) that all of the resulting 
    individual survey averages for the area be averaged, themselves, across 
    all of the surveys in the series. This approach removes a significant 
    source of distortion, simplifies calculations, and improves the 
    representativeness of the number that we use to make the important 
    decision on whether the gasoline in an area has passed or failed a 
    survey series.
    2. Clarification of Applicability of Survey Precision Requirements 
    (Sec. 80.68(c)(13)(iii))
        The intent of the survey precision requirements set forth in the 
    regulations (Sec. 80.68(c)(13)(iii)) was to ensure that errors (in 
    either direction) in survey or survey series pass/fail determinations 
    would be unlikely. Without these requirements survey managers would be 
    able to trade off risk of inappropriate survey failure against survey 
    costs, and the environment would not be protected against the increased 
    risk of errors in the other direction resulting from insufficient 
    sampling.
        Thus the precision requirements should apply to the body of data 
    that serves as the basis of each pass/fail determination. As currently 
    written, the regulations attach the precision requirements exclusively 
    to individual surveys without making it clear that for certain survey 
    parameters (for example, oxygen under the simple model) the pass/fail 
    determination is made against a year-long series of surveys rather than 
    against a single survey. The regulations would therefore be altered to 
    attach the precision requirements to the appropriate body of data for 
    each determination--to the individual survey where the parameters being 
    evaluated are ozone-related and to the survey series for other 
    parameters.
    
    F. Downstream Oxygen Blending (Sec. 80.69)
    
    1. Refiner ``Hand-Blending'' of RBOB (Secs. 80.69 (a)(2), (a)(8) and 
    (a)(9))
        Under Sec. 80.65(c)(1) refiners and importers are required to meet 
    all RFG standards for RBOB, except for the oxygen standard. Under 
    Sec. 80.65(c)(2) the oxygen standard for RBOB is met by the oxygenate 
    blender. Section 80.69(a)(2) requires refiners and importers to 
    determine the non-oxygen properties of RBOB by blending the appropriate 
    type and amount of oxygenate with a sample of the RBOB (sometimes 
    called a ``hand blend''), and testing the properties of the resulting 
    RFG. Under Sec. 80.69(a) an RBOB refiner or importer is allowed to hand 
    blend the amount of oxygenate actually used by the oxygenate blender 
    only if, inter alia, a quality assurance program is carried out over 
    the oxygenate blending operation. In the absence of such a quality 
    assurance program, under Sec. 80.69(a)(8) specified types and amounts 
    of oxygenate must be hand blended.
        EPA is proposing to revise Sec. 80.69(a)(2) to provide additional 
    guidance regarding the type and amount of oxygenate that must be hand 
    blended, and to move the hand blending
    
    [[Page 37353]]
    
    instructions from Sec. 80.69(a)(8) to Sec. 80.69(a)(2) in order to 
    improve the organization of this section. The additional guidance would 
    apply in the case of ``refiner specified'' RBOB (i.e., neither ``any 
    oxygenate'' nor ``ether only'') for which the refiner or importer has 
    specified options for more than one oxygenate type, or for a range of 
    oxygenate volumes. EPA is proposing that the hand blend for such RFG 
    must be formulated with the most conservative options. For example, 
    where an RBOB specification allowed ethanol and other oxygenates, the 
    hand blend would have to be formulated using ethanol, because ethanol, 
    as compared with other oxygenates at the same weight percent oxygen, 
    generally results in RFG with worse emissions performance.
        Section 80.69(a)(9) specifies that where RBOB is designated as 
    ``refiner specified'' but the quality assurance program is not 
    completed, the hand blend must be formulated with 4.0 vol% ethanol. EPA 
    is proposing to merge this paragraph with Sec. 80.69(a)(2).
    2. Deletion of Secs. 80.69 (a)(4) and (a)(10)
        Section 80.69(a)(4) requires refiners of RBOB to determine 
    properties of the RBOB, which would allow downstream parties to 
    determine if any contamination had occurred and thereby ensure that the 
    RFG produced using the RBOB would meet applicable standards. Section 
    80.69(a)(4) was included in the final reformulated gasoline regulation 
    to facilitate quality assurance programs by downstream parties who 
    handle RBOB, particularly where RBOB from a specific refinery travels 
    as a segregated product. However, EPA believes that, in practice, most 
    RBOB is being transported in a fungible manner. As a result, there is 
    little value to Sec. 80.69(a)(4) and EPA is proposing to delete this 
    requirement. EPA believes that downstream parties may conduct fully 
    adequate quality assurance programs over RBOB by hand blending the 
    oxygenate type and amount specified for the RBOB and testing the hand 
    blended sample to determine compliance with applicable standards.
        Section 80.69(a)(10) requires refiners and importers of RBOB to 
    include in the RBOB blending specifications a range of oxygenate types 
    and amounts for all RBOB. This requirement was included in the RFG rule 
    because at the time the RFG regulations were promulgated it was not 
    clear the types of RBOB regulated parties would choose to produce. As a 
    result, the regulations were structured to accommodate a wide variety 
    of RBOB types. In practice, however, refiners and importers of RBOB 
    have chosen to produce only a limited slate of RBOB types, and mainly 
    only two types: generic ``ether-only'' RBOB, and RBOB with blending 
    instructions that are specific to the refiner and that is shipped in a 
    segregated manner. As a result, EPA now believes that Sec. 80.69(a)(10) 
    creates a burden on refiners and importers of RBOB, yet provides little 
    or no benefit to oxygenate blenders or to the environment. Accordingly, 
    EPA is proposing to eliminate this requirement.
    3. Refiner Evaluation of RFG Produced by Oxygenate Blender 
    (Sec. 80.69(a)(7))
        In the case of a refiner of RBOB conducting oversight over the RFG 
    produced at a downstream oxygen blending facility, the refiner of the 
    RBOB is required to calculate the non-oxygen parameter values for the 
    RFG produced using the RBOB. To do so, the refiner may use either the 
    oxygen blending assumptions under Sec. 80.69(a)(2) or the actual oxygen 
    blending levels if the refiner meets the contractual and quality 
    assurance testing requirements specified in Sec. 80.69(a)(5) through 
    (7).
        The quality assurance provisions of Sec. 80.69(a)(7) require the 
    refiner to use sampling and testing to ensure that the RFG produced by 
    the downstream oxygen blender meets ``applicable standards.'' The 
    applicable standards are not further specified in that paragraph.
        EPA is proposing to amend Sec. 80.69(a)(7) to require the refiner 
    to evaluate the RFG produced by an oxygenate blender for the oxygenate 
    type and oxygen amount, but not for other RFG standards. The principal 
    purpose of the Sec. 80.69(a)(7) oversight program is to ensure that the 
    oxygenate blender uses the proper type and amount of oxygen, to support 
    the refiner's RBOB compliance calculations. Other sections of the 
    regulations address quality assurance sampling and testing for all 
    standards that apply at all downstream locations, including at 
    oxygenate blending facilities. See, for example, Sec. 80.79(c), which 
    requires quality assurance sampling and testing as an affirmative 
    defense for violations of downstream standards. As a result, EPA 
    believes it is most appropriate to require sampling and testing only 
    for oxygenate type and amount under Sec. 80.69(a)(7).
    4. Oxygenate Blending Instructions (Sec. 80.69(b)(1))
        Under Sec. 80.69(b)(1) oxygenate blenders are required to blend 
    with RBOB only the type and amount of oxygenate that is specified for 
    the RBOB. EPA is proposing to amend this section to provide additional 
    guidance to oxygenate blenders regarding this blending. In addition, 
    EPA is proposing regulations that would specify the allowed quantity of 
    de minimis, extraneous, oxygenates that may be present in an oxygenate 
    blending operation.
        EPA is proposing oxygenate blending requirements under 
    Sec. 80.69(b)(1) that are in accord with the RBOB blending 
    instructions. In addition, EPA is proposing language that would clarify 
    that the minimum oxygenate volume that could be used is the minimum 
    volume specification for the RBOB, and that the oxygenate blender is 
    free to add additional oxygenate up to the maximum oxygen standard 
    under Sec. 80.41(g).
        EPA understands that when RBOB is blended with oxygenate to produce 
    RFG at oxygenate blending facilities, the RFG may contain de minimis 
    amounts of oxygenate other than the principal oxygenate that is 
    blended. These oxygenates may result, for example, when RBOB is shipped 
    via pipeline adjacent to RFG (that necessarily would contain 
    oxygenate), and these products are imperfectly segregated. Also, when 
    an oxygenate is produced it is normal that de minimis amounts of other 
    oxygenates also are produced and that remain present in the principal 
    oxygenate.
        EPA believes that de minimis quantities of oxygenate that are in 
    addition to the principal oxygenate used to produce RFG do not degrade 
    the quality of RFG beyond a trivial amount. As a result, EPA is 
    proposing regulations that would specifically allow de minimis amounts 
    of incidental oxygenate, and that would specify the oxygenate amounts 
    that would be considered de minimis. However, EPA is also proposing 
    that these incidental oxygenates could not have been intentionally 
    blended, because the purpose of this proposed provision is to address 
    inadvertent oxygenate anomalies and not to provide additional oxygenate 
    blending options.
    5. Every-Batch Sampling and Testing Requirement for Splash Blenders 
    (Proposed Sec. 80.69(b)(5))
        Under Sec. 80.69(b)(4), an oxygenate blender who meets the oxygen 
    standard on average is required to sample and test each batch of RFG 
    produced to determine the batch's oxygen content, and assign a number 
    to the batch for reporting purposes. This every-batch sampling and 
    testing requirement was intended to be applied regardless of
    
    [[Page 37354]]
    
    whether the oxygenate blending is carried out in a large terminal tank 
    or through blending in trucks (sometimes called splash blending).
        Every-batch sampling and testing is required in order to give the 
    oxygenate blender the best information with which to calculate the 
    average oxygen content of RFG produced. EPA believes that oxygenate 
    blenders, like other parties who produce RFG, should use adequate 
    procedures to determine, with great certainty, the oxygen content of 
    RBOB produced. This is particularly true of parties who meet the oxygen 
    standard (or other standards) on average, because, in part, any errors 
    in calculating average oxygen content could result in the transfer to 
    other parties of invalid oxygen credits. Every-batch sampling and 
    testing provides this certainty.
        However, EPA believes that this every-batch sampling requirement 
    adds significant difficulties in the case of oxygenate splash blenders. 
    As a result, EPA is proposing to add Sec. 80.69(b)(5) which would allow 
    oxygenate splash blenders to meet the oxygen standard on average 
    without conducting every-batch sampling and testing under certain 
    conditions. These conditions, which are described below, would require 
    the oxygenate blender to use procedures that give certainty about 
    oxygen use, and that, taken together, EPA believes are as effective as 
    every-batch sampling.
        a. Computer-controlled oxygenate blending required. Under the 
    proposal, the oxygenate blending would have to be carried out using 
    computer-controlled in-line or sequential blending that operates in 
    such a manner that the volumes of oxygenate and RBOB are automatically 
    dispensed when a particular grade of gasoline is selected for loading 
    into a truck, and where no operator instructions are required regarding 
    the oxygenate-RBOB proportions when an individual truck is loaded. 
    Thus, this alternative averaging approach would not be available where 
    the oxygenate and RBOB are separately metered into a truck, regardless 
    of whether the separate metering occurs at the same terminal or at 
    different terminals.
        b. Oxygenate blender must operate blending equipment. The oxygenate 
    blender would be required to be the party who operates the computer-
    controlled in-line or sequential blending equipment. Thus, this 
    alternative averaging approach would not be available to a party who 
    receives delivery of splash blended RFG into trucks at a terminal if 
    the terminal is not operated by that party, regardless of whether the 
    receiving party is a registered oxygenate blender.
        c. Compliance calculations. The oxygenate blender would be required 
    to base its compliance calculations on the volumes and properties of 
    RBOB and oxygenate used during a period no longer than one calendar 
    month. In calculating the oxygen content of the RFG produced, the 
    oxygenate blender would be required to use either assumptions regarding 
    the specific gravities of the oxygenate and RBOB blended, or the 
    oxygenate blender would be required to measure the measured specific 
    gravities of all oxygenate and RBOB blended in the blending operation. 
    Similarly, with regard to the denaturant content of the ethanol (if 
    used), an oxygenate blender would be required to use a denaturant 
    content of 5 vol% and to support this value with documents from the 
    ethanol supplier and a quality assurance program, or the oxygenate 
    blender would be required to determine the denaturant content of all 
    ethanol used through sampling and testing.
        d. Quality assurance sampling and testing. An oxygenate blender who 
    meets the oxygen standard on average using these procedures would be 
    required to conduct a program of quality assurance sampling and testing 
    of the RFG produced, using the procedures and at the frequencies 
    specified under Sec. 80.69(e)(2).
        e. Attest procedures (Secs. 80.129 and 80.134). Under Sec. 80.65(h) 
    any oxygenate blender who meets the oxygen standard on average is 
    required to commission an annual attest engagement, to be conducted 
    under the terms of subpart F. EPA is proposing to add attest procedures 
    that would apply in the case of an oxygenate splash blender who meets 
    the oxygen standard on average under the proposed procedures. In 
    addition, EPA is proposing record keeping requirements that would apply 
    to such an oxygenate blender. The records which would be kept are those 
    EPA believes are necessary to an EPA auditor, or an independent 
    auditor, to ensure the proposed procedures were properly completed.
    
    G. References to Renewable Oxygenate Requirements (Sec. 80.83)
    
        On August 2, 1994, EPA promulgated regulations that would have 
    required the use of ``renewable'' oxygenates to meet a portion of the 
    oxygenate standard for RFG. See, 59 FR 39290 (August 2, 1994). However, 
    implementation of the renewable oxygenate requirements was stayed 
    effective September 13, 1994, as a result of a legal challenge filed in 
    the United States Court of Appeals for the DC Circuit. See, 59 FR 60715 
    (November 28, 1994). The Court of Appeals ultimately held that the 
    renewable oxygenate requirements for RFG are invalid, as they are not 
    authorized under sections 211 (c) or (k) of the Clean Air Act. American 
    Petroleum Institute v. EPA, 52 F.3rd 1113 (D.C. Cir. 1995).
        This proposal would remove the regulatory language covered by that 
    decision.
        The proposed changes relating to renewable oxygenates are shown in 
    the following table.
    
    Sec.  80.2(ss)...............  Current paragraph is deleted because it  
                                    applies only to renewable oxygenate     
                                    requirements. A new paragraph (ss) is   
                                    proposed which would define ``tank      
                                    truck.''                                
    Sec.  80.2(tt)...............  Paragraph is deleted because it applies  
                                    only to renewable oxygenate             
                                    requirements.                           
    Sec.  80.2(uu)...............  Paragraph is deleted because it applies  
                                    only to renewable oxygenate             
                                    requirements.                           
    Sec.  80.65(d)(2)(vi) (C)      Paragraphs are deleted because they apply
     through (E).                   only to renewable oxygenate             
                                    requirements.                           
    Sec.  80.83..................  Current section is deleted because it    
                                    applies only to renewable oxygenate     
                                    requirements. A new section 80.83 is    
                                    proposed which would provide procedures 
                                    for handling gasoline treated as        
                                    blendstock.                             
    Sec.  80.128(e)(2)...........  Paragraph is revised to delete language  
                                    that applies only to renewable oxygenate
                                    requirements.                           
    Sec.  80.128(e)(6)...........  Paragraph is deleted because it applies  
                                    only to renewable oxygenate             
                                    requirements.                           
    Sec.  80.129(a)..............  Paragraph is revised to delete language  
                                    that applies only to renewable oxygenate
                                    requirements.                           
    Sec.  80.129(d)(3)(iii)......  Paragraph is deleted because it applies  
                                    only to renewable oxygenate             
                                    requirements.                           
                                                                            
    
    
    [[Page 37355]]
    
        In certain cases, the deleted text is replaced by regulatory 
    language discussed elsewhere in this proposal.
    
    H. Covered Areas (Sec. 80.70)
    
        Under Clean Air Act Sec. 211(k)(10)(D), any ozone nonattainment 
    area that is reclassified as Severe becomes an RFG covered area. This 
    inclusion in the RFG program occurs one year following the date of 
    reclassification.
        Effective June 1, 1995, the Sacramento, California, ozone 
    nonattainment area was reclassified from Serious to Severe (60 FR 20237 
    (April 25, 1995)). Sacramento, therefore, became a covered area as of 
    June 1, 1996. Today's proposal would update the list of RFG covered 
    areas in Sec. 80.70 to include Sacramento.
    
    I. Record Keeping Requirements (Sec. 80.74)
    
    1. Clarification of test results record keeping (Secs. 80.74(a) and 
    80.104(a))
        Sections 80.74(a)(2)(iii) and 80.104(a)(2)(i) require regulated 
    parties to keep the results of tests conducted of reformulated and 
    conventional gasoline. Parties have asked EPA to clarify this 
    requirement, and in particular have asked whether these regulations 
    require parties to keep copies of all documents that contain test 
    results.
        In order to clarify these requirements, EPA is proposing changes to 
    Secs. 80.74(a)(2)(iii) and 80.104(a)(2)(i), that would specify that 
    parties are required to keep the original result for each test 
    performed. Thus, for example, where a test is performed using a testing 
    apparatus that automatically generates a printed document containing 
    the test result, this printed document must be kept. Where a test is 
    performed using an apparatus that does not generate a print out EPA is 
    proposing that the party would be required to keep the first recorded 
    test result, such as the chemist's laboratory log book.
        In addition, EPA is proposing that parties would be required to 
    keep any other record that contains a test result that is not identical 
    to the original result. A non-identical test result could occur where a 
    party determines that an original test result is in error because of 
    laboratory error, for example. In such a case, the party would be 
    required to keep both the original test result and the corrected test 
    result. This proposed requirement would allow EPA, during the course of 
    an audit or inspection, to review changes that are made to test 
    results, to determine if the changes are appropriate.
    2. Records To Be Kept by Refiners and Importers (Proposed 
    Sec. 80.74(b)(7))
        EPA is proposing to add Sec. 80.74(b)(7) which would require 
    retention of records that reflect the physical movement of gasoline 
    treated as blendstock (GTAB) from the point of importation to the point 
    of blending to produce reformulated gasoline. (See Preamble Section 
    V.C. concerning the proposed requirements for GTAB.)
    3. Records To Be Kept by Independent Laboratories (Proposed 
    Sec. 80.74(h))
        EPA is proposing to add Sec. 80.74(h) which would require 
    laboratories serving as independent laboratories under proposed 
    Sec. 80.72 to retain records as required under Secs. 80.74(a)(2) and 
    80.72(c)(1).
    
    J. Product Transfer Documentation (Secs. 80.77 and 80.106)
    
        Product transfer documentation (PTD) requirements at Secs. 80.77 
    and 80.106 are intended to insure that on each occasion that any person 
    transfers custody or title of any RFG, RBOB or conventional gasoline, 
    other than when gasoline is sold or dispensed for use in motor vehicles 
    at a retail outlet or wholesale-purchaser-consumer facility, the 
    transferor produce, and provide to the transferee, documents that 
    contain certain information. This information would enable the 
    transferee to know enough about the gasoline being received to meet the 
    requirements of the RFG program. In addition, the PTD documents, which 
    parties are required to keep under Secs. 80.74(a)(1) and 
    80.104(a)(2)(vi) and (vii), help EPA identify the source of any 
    gasoline found to violate applicable standards.
        EPA today is proposing to amend Secs. 80.77 and 80.106 to clarify 
    the following PTD requirements.
    1. Introductory Text of Secs. 80.77 and 80.106
        Section 80.77 requires a transferor to provide PTDs to the 
    transferee on each occasion involving a transfer of custody or title of 
    RFG or RBOB. Section 80.77 does not distinguish between transfers of 
    custody and transfers of title concerning the timing necessary for 
    transfer of PTD information. EPA, however, believes the two situations 
    may differ in this regard. In the case of transfers of custody, the PTD 
    information should be transferred before, during, or immediately 
    following the actual transfer because the transferee will have custody 
    of the gasoline in question and must know how to handle it. However, 
    since transfers of title do not always involve the physical handling of 
    the gasoline, EPA believes a transferee should have the option to rely 
    on the custody transferee to properly handle the gasoline (e.g., where 
    the custody transferee is a common carrier pipeline.) Therefore, in the 
    case of title transfers, EPA believes there is little need for the 
    required PTD information to be transferred at the time of the transfer 
    of the product. Accordingly, EPA is proposing, in the case of title 
    transfers, to allow up to thirty days in which to transfer the required 
    information. EPA believes this timing would allow parties to transfer 
    the required information using documents that are transferred as a part 
    of normal business dealings, and as a result would ease the burden of 
    meeting the PTD requirements.
        The introductory text of Sec. 80.77 excludes from the PTD 
    requirements gasoline sold or dispensed for use in motor vehicles at a 
    retail outlet or wholesale purchaser-consumer facility. Section 80.106 
    does not contain this exclusion, which EPA believes was an inadvertent 
    omission when the final rule was promulgated. Accordingly, EPA is 
    proposing to revise Sec. 80.106 to conform to Sec. 80.77 in this 
    regard. EPA is also proposing to modify the introductory text of 
    Sec. 80.77 to clarify that this exclusion applies to gasoline sold or 
    dispensed at a retail outlet or wholesale purchaser-consumer facility 
    for use by any ultimate consumer, and not only for use in motor 
    vehicles.
        In addition, EPA now believes that the PTD information is of little 
    value when conventional gasoline is delivered to a retailer or 
    wholesale purchaser-consumer in a conventional gasoline area. 
    Accordingly, EPA is proposing to exclude from the PTD requirements 
    transfers of conventional gasoline to retailers and wholesale-purchaser 
    consumers in conventional gasoline areas. Note, however, that the PTD 
    requirements of Sec. 80.106 would continue to apply for all other 
    transfers of conventional gasoline. Note also that the PTD requirements 
    of Sec. 80.77 for RFG and RBOB would continue to apply to all transfers 
    of RFG and RBOB (other than when the gasoline is sold or dispensed by a 
    retail outlet or wholesale purchaser-consumer facility for use by 
    ultimate consumers), including transfers in which RFG is delivered to a 
    retail outlet or wholesale purchaser-consumer.
    2. Identification of the Gasoline (Sec. 80.77(f) and Sec. 80.77(g)(3)).
        EPA is proposing to amend Sec. 80.77(f) to delete reference to 
    conventional gasoline, since the requirements of Sec. 80.77 do not 
    apply to conventional gasoline. EPA is proposing to amend
    
    [[Page 37356]]
    
    Sec. 80.77(g)(3) to delete reference to RBOB. This section requires 
    parties to identify whether the product contains ethanol, and RBOB, by 
    definition, does not contain oxygenate. In addition, EPA is proposing 
    to add references to RBOB to Secs. 80.77 (c) and (f) to specify that 
    these PTD requirements apply to RBOB as well as to RFG and conventional 
    gasoline.
    3. Elimination of PTD Requirement for Inclusion of Registration Numbers 
    (Sec. 80.77(j) and Sec. 80.106(a)(1)(vi))
        Sections 80.77(j) and 80.106(a)(1)(vi) require, in the case of 
    transferors and transferees who are refiners, importers or oxygenate 
    blenders, that the EPA assigned registration number of those persons be 
    included on the PTDs. EPA received comments that this requirement is 
    overly burdensome in certain circumstances, particularly downstream of 
    the refiner/importer/oxygenate blender where such information may not 
    be readily available. Based on experience with the program, EPA 
    believes that this requirement has only limited value as a means of 
    identifying and tracking the gasoline, and that EPA will be able to 
    adequately enforce the regulations without inclusion of the assigned 
    registration number on the transfer documents. As a result, EPA is 
    proposing to eliminate the requirements to include registration numbers 
    in PTDs.
    4. Use of Product Codes (proposed Sec. 80.77(j))
        The petroleum industry historically has used product codes to 
    identify product type in business transactions involving the transfer 
    of title or custody of petroleum products. For example, all pipelines 
    that transport refined petroleum products use codes to identify the 
    various types of petroleum products that are transported. These product 
    codes are well-known to persons who operate a pipeline, or who supply 
    products to or receive products from a pipeline. These pipeline codes 
    are used as a shorthand for the myriad petroleum products moving 
    through the distribution system, and make product identification 
    easier.19 In addition, product codes are used to identify 
    petroleum products in many of the documents used to memorialize 
    transfers of title and custody in normal business dealings, in part 
    because the codes occupy less space on the documents than the full 
    product names would require.
    ---------------------------------------------------------------------------
    
        \19\ For example, Colonial Pipeline product code A1 means: 
    gasoline; RFG; VOC-controlled for Region 1; non-OPRG; simple model; 
    87 octane; benzene maximum of 1.18 vol%; oxygen minimum of 1.5 wt% 
    and maximum of 2.7 wt%; RVP maximum of 7.4 psi; and no heavy metals.
    ---------------------------------------------------------------------------
    
        EPA is proposing to add Sec. 80.77(j) to allow the use of product 
    codes for certain information required on PTDs to accommodate this 
    practice, but under conditions that would ensure that the codes would 
    satisfy the goals of the PTD requirement. In particular, EPA is 
    proposing that product codes could be used to satisfy PTD requirements 
    related to identifying the product type (i.e., RFG, RBOB or 
    conventional gasoline); for RFG and RBOB, the designations and minimum 
    and maximum standards; and for RBOB, the oxygenate blending 
    specifications. Product codes, used to meet these PTD requirements 
    would have to fully reflect the PTD requirements. Thus, a product code 
    that referred to ``VOC controlled RFG,'' without more, would not meet 
    the requirement in Sec. 80.77(g)(1)(i) to separately identify RFG that 
    is VOC controlled for Region 1 and Region 2. Similarly, where product 
    codes are used to identify minimum and maximum standards, as required 
    in Sec. 80.77(g)(2), the product codes would have to reflect the actual 
    numerical value for the minimum and maximum standards.
        In addition, EPA is proposing that the codes would have to be 
    standardized throughout the distribution system in which they are used, 
    and that transferees would have to be given the information necessary 
    to know the meaning of the product codes.
        EPA is not proposing that product codes could be used to satisfy 
    PTD requirements unrelated to product types. It is EPA's understanding 
    that product codes used in normal business practice are limited to 
    product types. In addition, EPA believes that other PTD information, 
    such as the name and address of the transferor and transferee, volume 
    of product, and date of transfer, is included in full text in documents 
    historically used to memorialize transfers of petroleum products.
        In addition, EPA is not proposing that product codes could be used 
    for transfers of gasoline to truck carriers, retail outlets, or 
    wholesale purchaser-consumer facilities. EPA believes that these types 
    of regulated parties may not be sufficiently familiar with product 
    codes to know their full meaning. This belief is based, in part, on 
    EPA's experience in enforcing compliance with the RFG requirements by 
    truck carriers, retailers and wholesale users. EPA has found that in 
    most cases where codes were used to supply required PTD information to 
    these parties, the parties did not know the meaning of the product 
    codes even where the gasoline supplier had previously provided the 
    information necessary to interpret the product codes.
    
    V. Enforcement
    
    A. Prohibitions (Sec. 80.78)
    
    1. Clarification of Prohibitions (Sec. 80.78(a) (1) through (4))
        Sections 80.78(a) (1) and (2) prohibit activities that could result 
    in the use of non-RFG in RFG covered areas. Specifically, these 
    sections prohibit the manufacture and marketing of gasoline represented 
    to be RFG unless the gasoline meets the requirements for federally 
    certified RFG, and prohibit the distribution and sale of non-RFG for 
    use by ultimate consumers in RFG covered areas. EPA believes, however, 
    that the current text of Sec. 80.78(a) should be made clearer with 
    regard to the scope of these prohibitions. As a result, EPA is 
    proposing to revise the introductory text of Sec. 80.78(a)(1) and 
    Sec. 80.78(a)(2), to clarify these prohibitions. In addition, EPA is 
    proposing to delete Sec. 80.78(a)(3), since this section refers to a 
    conventional gasoline marker and the regulations currently do not 
    require a marker for a conventional gasoline. EPA is also proposing to 
    revise Sec. 80.78(a)(4) for purposes of consistency with the revised 
    text of Secs. 80.78(a) (1) and (2).
    2. Addition of ``Causation'' of Prohibited Activities 
    (Sec. 80.78(a)(10))
        Section 80.78(a) prohibits certain conduct on the part of parties 
    who are engaged in gasoline industry activities such as gasoline 
    manufacturing and selling, distributing, dispensing, supplying, 
    storing, or transporting. Under this subsection, however, parties 
    currently are liable for ``causing'' prohibited conduct only in the 
    case of gasoline that is transported in violation of the regulations.
        EPA now believes there are other situations where a party may, in 
    fact, cause another to commit a prohibited act, and in those cases, the 
    causing party also should be liable for the violation. For example, a 
    distributor who delivers to a retail outlet reformulated gasoline that 
    fails to meet one or more standards would have caused the retailer to 
    sell and offer for sale prohibited gasoline.
        As a result, EPA is proposing that parties would be liable not only 
    for committing prohibited actions, but also for causing another party 
    to commit a prohibited act.
    3. Transition from Simple Model to Complex Model in 1998
        Under Sec. 80.41(i), refiners and importers of both reformulated 
    and conventional gasoline have the option of using either the simple 
    model or the
    
    [[Page 37357]]
    
    early complex model prior to January 1, 1998. Particularly in the case 
    of producers of reformulated gasoline, EPA believes that most parties 
    will elect the simple model standards. Beginning on January 1, 1998, 
    however, refiners and importers must meet the complex model standards 
    for all reformulated and conventional gasoline produced or imported. As 
    a result, in January 1998, it will be necessary for parties to 
    transition from the simple model to the complex model, yet the current 
    regulations do not specify how regulated parties should accomplish this 
    transition. Therefore, EPA now is proposing the manner in which this 
    transition would occur.
        Under the proposal, any gasoline produced or imported during 
    calendar year 1997, through December 31, 1997, would be subject to the 
    simple or early complex model standards in the same manner as during 
    calendar years 1995 and 1996. Thus, any simple or early complex model 
    standards that are met on an annual average basis for 1997 would be met 
    for all gasoline produced during calendar year 1997.
        Any gasoline produced or imported beginning on January 1, 1998, 
    would be subject to the complex model standards. Thus, conventional 
    gasoline produced during calendar 1998 would be subject to the annual 
    average anti-dumping complex model standards specified in section 
    101(b)(3), and reformulated gasoline produced during calendar 1998 
    would be subject to the Phase I complex model standards specified in 
    Secs. 80.41 (c) and (d).
        However, beginning on January 1, 1998, the gasoline located in the 
    distribution system would be a mixture of gasoline produced to meet the 
    simple model standards and gasoline produced to meet the complex model 
    standards. In the case of reformulated gasoline, such a mixture may not 
    meet certain standards that apply at downstream locations or that are 
    evaluated under the gasoline quality surveys, i.e., the toxics and 
    NOX emissions performance standards.20 As a 
    result, EPA is proposing that gasoline quality surveys conducted during 
    the period January 1, 1998, through March 31, 1998, will not include 
    evaluation for toxics or NOX emissions performance. During 
    this period, however, EPA would continue to enforce the complex model 
    standards for oxygen and benzene content that apply at downstream 
    locations, and gasoline quality surveys conducted during this period 
    would include evaluations for oxygen and benzene content. Beginning on 
    May 1, 1998, all applicable complex model standards would be enforced 
    at all locations, and gasoline quality surveys would evaluate with all 
    complex model standards.
    ---------------------------------------------------------------------------
    
        \20\ There is no simple model NOX standard, so that a 
    mixture of simple model and complex model gasoline could fail to 
    meet the complex model NOX standard. Similarly, a mixture 
    of simple and complex model gasoline could not be evaluated for 
    compliance with either the simple model or the complex model toxics 
    emissions performance standards.
        The standards for oxygen and benzene content are the same under 
    the simple and complex models, so that a mixture of simple and 
    complex model reformulated gasoline could be evaluated for 
    compliance with these standards. The standards for VOC and 
    NOX emissions performance are not evaluated for 
    downstream compliance until the beginning of the high ozone season 
    on May 1 each year, and as a result should not be affected by the 
    transition from the simple to the complex model in early 1998.
    ---------------------------------------------------------------------------
    
        EPA believes that the three month period, January through March 
    1998, would be sufficient time for parties to transition the gasoline 
    at all locations in the distribution system from gasoline produced to 
    meet simple model standards to gasoline produced to meet complex model 
    standards. This transition period is similar to the time necessary to 
    transition to the VOC-control standards each Spring; i.e., terminals 
    are able to complete their transition to the new standard about 60 days 
    after refiners begin producing gasoline to the new standard, and retail 
    outlets complete their transition during the next 30 days.
    4. Amount of Oxygenate Permitted to be Added to RBOB (Sec. 80.78(a)(7))
        Section 80.78(a)(7) requires that RBOB may be blended only with 
    oxygenate of the type and amount, or within the range of amounts, 
    specified by the refiner or importer at the time the RBOB was produced 
    or imported. Today's proposal revises Sec. 80.78(1)(7) to clarify that 
    parties may add oxygenate amounts in excess of the minimum required by 
    the refiner or importer up to the amount allowed by the oxygen maximum 
    standard under Sec. 80.41(g).21
    ---------------------------------------------------------------------------
    
        \21\ The amount of oxygen added also may not exceed the maximum 
    amount allowed under section 211(f) of the Clean Air Act. The 
    maximum amount allowed under section 211(f) is the amount that is 
    substantially similar to gasoline used in the motor vehicle 
    certification process, or allowed under a waiver granted under 
    section 211(f)(4). In 1991, EPA issued an interpretative rule 
    increasing the maximum amount of oxygen that EPA believes is allowed 
    under the substantially similar criteria of section 211(f) from 2.0 
    to 2.7 wt% oxygen. See 56 FR 5352 (February 11, 1991). Ethanol is 
    allowed in amounts up to 10% volume pursuant to a waiver granted 
    under section 211(f)(4). See 44 FR 20777 (April 6, 1979).
    ---------------------------------------------------------------------------
    
    5. Categories of Gasoline Use within Covered Areas that are Exempt from 
    RFG Requirements (proposed Sec. 80.78(a)(11))
        Section 211(k)(5) of the Clean Air Act describes the scope of the 
    requirement to use RFG in the reformulated gasoline covered areas:
    
        (5) Prohibition.--Effective beginning January 1, 1995, each of 
    the following shall be a violation of this section:
        (A) The sale or dispensing by any person of conventional 
    gasoline to ultimate consumers in any covered area.
    * * * * *
    This statutory prohibition on the sale or dispensing of conventional 
    gasoline in RFG covered areas is not restricted to gasoline used to 
    fuel motor vehicles, but rather applies to all gasoline sold or 
    dispensed within an RFG covered area to any consumer, regardless of the 
    use. The prohibition, therefore, would include gasoline sold or 
    dispensed for uses such as in motor vehicles, boats, construction 
    equipment, recreational vehicles, and lawn and garden equipment.
        EPA is proposing to exempt parties from this prohibition in the 
    following limited situations: gasoline used for research, development 
    and testing purposes; aviation gasoline sold or dispensed for use in 
    aircraft, including gasoline that has properties identical to motor 
    vehicle gasoline that is sold or dispensed solely for use in aircraft; 
    and gasoline sold or dispensed for use in racing vehicles.
        EPA recognizes that there may be facilities located within an RFG 
    covered area that conduct beneficial research, development, and testing 
    programs which require the use of conventional gasoline. Today's 
    proposed rule, therefore, contains provisions for obtaining an 
    exemption from the prohibitions at Sec. 80.78(a)(1) for persons 
    distributing, transporting, storing, selling or dispensing conventional 
    gasoline used for research, development, and testing purposes within 
    RFG covered areas.
        To be exempted from the prohibitions at Sec. 80.78(a)(1) for 
    research, development or testing under today's proposed rule, the 
    gasoline: would have to be properly identified in product transfer 
    documents as conventional gasoline to be used only for research, 
    development, or testing (as applicable); could not be sold to or from 
    retail gasoline outlets; could not be sold to or from wholesale 
    purchaser-consumer facilities unless the wholesale purchaser-consumer 
    is associated with the research, development, or testing; and would 
    have to be covered by an
    
    [[Page 37358]]
    
    annual research notification to EPA that includes information that 
    describes the purpose and scope of the program. EPA believes that these 
    are the least onerous requirements for industry which also will ensure 
    that non-RFG gasoline is used only for a legitimate research, 
    development, and testing purpose. Parties should be aware, however, 
    that the exemption proposed in today's rule would not exempt gasoline 
    used for research, development, and testing from complying with any 
    federal conventional gasoline requirements.
        Under today's proposal, any person distributing, transporting, 
    storing, selling or dispensing aviation and racing gasoline would be 
    required to clearly identify the gasoline as not reformulated to be 
    exempted from the prohibitions at Sec. 80.78(a)(1). If any of the 
    restricted gasoline were used in a manner inconsistent with the 
    restriction, a violation of the prohibited activity would have 
    occurred, and any person selling, dispensing, or using the gasoline 
    would be liable for the violation.
        EPA is proposing that the racing vehicle exemption would apply only 
    in the case of vehicles that are used exclusively as racing vehicles in 
    races that are sanctioned by generally recognized race sanctioning 
    bodies. In addition, the exception would apply only in the case of 
    vehicles that do not meet the definition of ``motor vehicle'' under 
    Clean Air Act section 216(2) and section 85.1703 22 and that 
    are not registered or licensed for use on or operated on public roads 
    or highways. Examples of generally recognized race sanctioning bodies 
    include the National Association for Stock Car Auto Racing, the Sports 
    Car Club of America, the National Hot Rod Association, the American 
    Motorcyclist Association, and the American Power Boat Association. The 
    racing vehicle exemption applies to use of racing vehicles during 
    practice and qualifying for, and competition in sanctioned races, and 
    applies to motorcycles and boats used exclusively in sanctioned races.
    ---------------------------------------------------------------------------
    
        \22\  Under Sec. 85.1703 a vehicle is a ``motor vehicle'' if it 
    is self propelled and capable of transporting a person or materials, 
    unless the vehicle meets one or more of the following criteria: (1) 
    A maximum speed of not more than 25 miles per hour; (2) the absence 
    of features customary for street use, such as a reverse gear, a 
    differential, and required safety features; or (3) the presence of 
    features that render the vehicle highly unsuitable for street use, 
    such as tracks.
    ---------------------------------------------------------------------------
    
        The rationale for the proposed exemption for aviation gasoline used 
    to fuel aircraft is based on safety considerations. Aviation gasoline 
    must satisfy performance criteria that are relevant to the safe 
    operation of aircraft, and this safety consideration outweighs the very 
    limited potential for adverse environmental effects from conventional 
    gasoline used in this manner. In addition, aircraft emissions normally 
    would not be confined to the covered area where the aircraft is fueled, 
    and could occur in significant part outside any RFG covered area. The 
    rationale for the proposed exemption for racing gasoline is based on 
    the special performance requirements for true race vehicles and the 
    limited volumes of gasoline involved. The environmental impact from 
    these exemptions is trivial or minimal, and the burden from refusing 
    these exemptions is potentially significant. EPA believes the 
    exemptions are warranted under these limited circumstances. See Alabama 
    Power Company v. Costle, 636 F.2d 323, 357 (D.C. Cir.1979).
        Nevertheless, EPA requests comments on whether the racing vehicle 
    exemption would cause increased air pollution in RFG covered areas that 
    is not trivial, and if so, whether such an environmental effect would 
    make the racing vehicle exemption inappropriate.
    6. Changing Service of Gasoline Storage Tanks (Sec. 80.78(a) (12) and 
    (13))
        Section 80.78(a) requires the segregation of several categories of 
    gasoline. These categories include the following:
    
    Reformulated gasoline may not be mixed with conventional gasoline and 
    sold as reformulated gasoline.
    Reformulated gasoline blendstock for oxygenate blending (RBOB) may not 
    be mixed with reformulated gasoline or conventional gasoline, and 
    RBOB's that have different oxygen requirements must be segregated from 
    each other.
    During the period January 1 through September 15 each year VOC-
    controlled reformulated gasoline that is produced using ethanol must be 
    segregated from VOC-controlled reformulated gasoline that is produced 
    using any other oxygenate, including at the retail level.
    Oxygenated fuels program reformulated gasoline (OPRG) must be 
    segregated from non-OPRG designated reformulated gasoline.
    
        These segregation requirements preclude the mixing of any amount of 
    the gasolines that must be segregated.23 Thus, if the type 
    of gasoline stored in a tank is changed (a change in the tank's 
    service), and the old gasoline type and the new gasoline type must be 
    segregated, the new gasoline may not be added unless the tank is 
    completely free of any amount of the old gasoline type.
    ---------------------------------------------------------------------------
    
        \23\ Reformulated gasoline may be mixed with conventional 
    gasoline, so long as the mixture is classified in the product 
    transfer documents as conventional gasoline and is used only outside 
    any reformulated gasoline covered area.
    ---------------------------------------------------------------------------
    
        A gasoline storage tank's service also may be changed in a manner 
    that results in some volume of blendstocks being mixed with 
    reformulated or conventional gasoline. For example, a storage tank's 
    service could be changed from blendstock (e.g., natural gasoline, 
    raffinate, naphtha) to reformulated or conventional gasoline, which 
    would result in mixing some volume of blendstock with the reformulated 
    or conventional gasoline. Under Secs. 80.65(c), 80.78(a)(5) and 
    80.101(d)(1) a party who combines any volume of blendstock with 
    reformulated or conventional gasoline has produced additional volume of 
    gasoline, which constitutes refining for which the refiner must meet 
    all standards and requirements that apply to refiners of reformulated 
    or conventional gasoline.
        EPA recognizes that when many gasoline storage tanks are pumped as 
    low as possible a residual volume of gasoline or blendstock remains in 
    the tank (called the tank ``heel''), and in the terminal's manifolds 
    and pipes that serve the tank. It is very difficult but not impossible 
    to eliminate these residual volumes. As a result, EPA is proposing that 
    in the limited situation related to changing the service of a gasoline 
    storage tank, pipe, or manifold for legitimate business reasons that 
    are unrelated to any goal of mixing dissimilar gasolines or blendstock, 
    that parties would be allowed to mix products that normally must remain 
    segregated. Under the proposal, parties changing the service of a 
    gasoline storage tank, pipe or manifold would have to meet a number of 
    conditions and constraints that are specified in the proposed 
    regulations, including measures that would minimize the volumes of 
    dissimilar gasolines that are mixed. In addition, when any mixture 
    would be classified as reformulated gasoline the party would be 
    required to sample and test the gasoline subsequent to mixing to show 
    the mixture meets all applicable reformulated gasoline standards.
        EPA also is proposing an additional option that would apply in the 
    case of a transition from reformulated gasoline blendstock for 
    oxygenate blending (``RBOB'') to RFG, and vice versa, at a terminal 
    where oxygenate is blended in trucks (splash-blended). This option 
    would be available only in a case where the oxygenate blender is unable 
    to meet the tank transition requirements discussed above.
    
    [[Page 37359]]
    
        This option is being proposed because in some cases the 
    requirements for tank transition under the proposed regulatory 
    revisions are not feasible without risk that a terminal would have to 
    be closed during at least part of the transition period. For example, 
    consider a terminal operator who wants to supply RFG containing MTBE 
    during the summer VOC season, and RFG containing ethanol outside the 
    VOC season. During the VOC season this party's storage tank would 
    contain MTBE-based RFG, while outside the VOC season the storage tank 
    would contain RBOB that would be splash-blended with ethanol at the 
    terminal. As a result, the party's terminal tank would have to 
    transition from RBOB to RFG in the spring, and from RFG to RBOB in the 
    fall. Under the change-of-service requirements described above, in the 
    spring the storage tank's RBOB content would have to be drawn-down to 
    the minimum level possible through normal pumping operations before any 
    RFG could be added to the tank. In order to meet this requirement, 
    however, the party may have to take the storage tank out of service if 
    the ``minimum level'' is reached before new product is available to be 
    transferred into the tank. If the terminal has limited tankage it could 
    be unable to supply gasoline during the time the storage tank remains 
    out of service, which could adversely affect gasoline supplies for some 
    parties. The same difficulty could occur when transitioning from RFG to 
    RBOB in the fall.
        As a result, EPA is proposing an option that would allow a party to 
    receive RFG in a tank containing RBOB in the Spring prior to the 
    beginning of the VOC season, and to receive RBOB in a tank containing 
    RFG in the Fall subsequent to the end of the VOC season. This option is 
    intended to minimize the likelihood a party would have to take a tank 
    out of service in order to transition product types.
        Under this option, parties could have a mixture of RFG and RBOB in 
    a storage tank during the transition period. The option would require 
    parties to ensure that all RFG downstream standards, including the 
    oxygen standard, are met during the transition. In particular, parties 
    would be required to adjust the rate of splash-blended oxygenate based 
    on sampling and testing of the RFG/RBOB mixture and the RFG produced 
    subsequent to splash blending. In addition, the transition must occur 
    outside the period VOC control standards apply at the terminal--
    normally May 1 through September 15 each year.
    
    B. Liability and Defenses (Sec. 80.79)
    
    1. Branded Refiner Defenses for Violations at Branded Retail Outlets 
    Directly Supplied by the Refiner (Sec. 80.79(b) (2) and (3))
        Section 80.79(b)(2) specifies the affirmative defense elements that 
    must be shown by a refiner for violations of the reformulated gasoline 
    standards that are found at branded downstream facilities. As currently 
    promulgated, this section addresses violations that are caused by a 
    reseller, distributor, oxygenate blender, or carrier that is supplied 
    by the refiner, or by a retailer or wholesale purchaser-consumer who is 
    supplied by one of these parties. The regulation does not specifically 
    address the case of a branded retailer or wholesale purchaser-consumer 
    who is supplied directly by the refiner. In addition, the current 
    regulation is silent regarding the defenses that would apply in the 
    case of a violation occurring at a facility carrying the brand name of 
    an importer who is not also a refiner.
        EPA believes the defense provisions should address violations that 
    occur at facilities that display the brand name of an importer that 
    would parallel the defense elements that apply to branded refiners, as 
    well as violations that are caused by retailers or wholesale purchaser-
    consumers that are directly supplied by a refiner or importer. EPA 
    believes that the degree of control available to importers over their 
    branded retail outlets is the same as the degree of control available 
    to refiners over their branded retail outlets. This control primarily 
    is available through contractual obligations that the refiner and 
    importer can impose on distributors and retailers who distribute or 
    sell gasoline under the brand name. As a result, EPA is proposing 
    modifications to Sec. 80.79(b)(2) that would make these changes.
    2. Truck Carrier Defenses (Sec. 80.79(c)(3); Proposed Sec. 80.2(ss); 
    Modifications to Secs. 80.28(g)(1)(iii); 80.30(g)(1)(i))
        Section 80.79(b) specifies the defenses for violations of the 
    prohibited activities under the reformulated gasoline program. Section 
    80.79(b)(1) states that a party, who is presumed liable for a 
    violation, can avoid liability if it can show: (1) That it did not 
    cause the violation, (2) the existence of appropriate product transfer 
    documents for the gasoline in question, and (3) that it conducted an 
    appropriate quality assurance sampling and testing program.
        These defenses apply to all regulated parties, including carriers. 
    In addition, under Sec. 80.79(b)(1)(iii)(B) a carrier may rely on 
    properly conducted quality assurance sampling and testing program 
    conducted by another party. Carrier is defined at 40 CFR 80.2(t) as a 
    party who stores or transports gasoline without taking title to the 
    gasoline.
        For one category of carriers--truck carriers--sampling and testing 
    may not always be the most appropriate form of quality assurance. The 
    purpose of a quality assurance requirement is, first and foremost, to 
    institutionalize preventive measures as the best way to detect and 
    avoid violations. The most typical role of truck carriers in the 
    gasoline distribution system is to transport gasoline from a terminal 
    to a retail outlet or wholesale consumer. Most violations caused by 
    truck carriers result when an inappropriate type of gasoline is 
    delivered. For example, a truck carrier would have caused a violation 
    if gasoline designated as conventional is delivered by the carrier to a 
    retail outlet located in a reformulated gasoline covered area. The most 
    appropriate quality assurance for a truck carrier to implement to avoid 
    this type of violation would be driver training on the proper types of 
    gasoline to deliver, and management oversight of product transfer 
    documents to ensure the proper type of gasoline has been delivered.
        It is EPA's understanding that truck carriers almost always load 
    gasoline into empty truck compartments. To the extent this is true, it 
    would be very unlikely the carrier could be responsible if the gasoline 
    loaded into the truck were off-spec for a regulated standard, such as 
    benzene or oxygen content. As a result, sampling and testing of 
    gasoline obtained from a truck compartment would not be particularly 
    effective for detecting violations caused by the carrier. In addition, 
    EPA has received comments from industry regarding the practicability of 
    drawing samples from truck compartments during the loading process, or 
    subsequent to loading. These comments conclude that the technical 
    aspects of collecting gasoline samples from truck compartments make 
    such sampling difficult, but not impossible. For example, the sampler 
    normally would be required to climb onto the top of the truck trailer 
    in order to gain access to the compartment lid, which could be 
    difficult particularly in adverse weather conditions.
        As a result, EPA is proposing to modify the defense elements under 
    40 CFR 80.79 as they pertain to truck carriers, to state that an 
    oversight program by a truck carrier may consist of, instead of 
    sampling and testing, a program to monitor compliance with the
    
    [[Page 37360]]
    
    requirements related to gasoline transport or storage, such as a 
    program to properly train truck drivers and review product transfer 
    documents to ensure that the proper type of gasoline is delivered. In 
    addition, EPA is proposing to add a definition of tank truck carrier to 
    40 CFR 80.2.
        EPA is not proposing a similar change to the reformulated gasoline 
    defense provisions for carriers other than truck carriers, such as 
    pipelines, barge operators, or for-hire terminals. EPA believes 
    carriers in these other categories are better able to collect gasoline 
    samples, and samples of the gasoline being transported or stored by 
    these categories are collected for commercial reasons on a routine 
    basis in the normal course of business. Nevertheless, EPA requests 
    comments regarding whether the changes proposed for truck carriers 
    should also be applied to other types of carriers.
        EPA also is proposing similar changes to the defense provisions for 
    truck carriers in the case of violations of the volatility requirements 
    at 40 CFR 80.28(g)(1), and violations of the diesel sulfur requirements 
    at 40 CFR 80.30(g)(1). The rationale for changing the volatility and 
    diesel sulfur defense provisions for truck carriers is the same as is 
    discussed above for reformulated gasoline.
    
    C. Gasoline Treated as Blendstock (Proposed Sec. 80.83; Minor Changes 
    to Sec. 80.74 and Sec. 80.104)
    
        Under 40 CFR 80.65(c) and 80.101(d) an importer must include all 
    imported product that meets the definition of gasoline in the 
    importer's compliance calculations for either reformulated or 
    conventional gasoline. If this imported gasoline is then processed by 
    blending with additional blendstock, the subsequent blending 
    constitutes a refinery operation for which all refiner requirements 
    must be met, including refinery standards, refiner sampling and 
    testing, independent sampling and testing in the case of reformulated 
    gasoline, recordkeeping, reporting, and attest engagements. Further, 
    the reformulated gasoline or anti-dumping standards for such an 
    operation must be met solely on the basis of the blendstocks used, and 
    the previously imported (and previously accounted for) gasoline may not 
    be included. This is true regardless of whether the subsequent 
    blending-refining is conducted by the original importer of the 
    gasoline, or by another party.
        One consequence of this requirement is that importers are not able 
    to conduct remedial blending of imported gasoline that is deficient 
    with regard to a specification (i.e., is ``off-spec'') prior to 
    certification as reformulated or conventional gasoline. For example, 
    consider an importer who receives a cargo of gasoline that the importer 
    intends to import as reformulated gasoline, but that on arrival in the 
    United States has a benzene content of 1.35 vol%, which is in excess of 
    the maximum benzene standard of 1.30 vol%. Because this gasoline fails 
    to meet one of the reformulated gasoline standards it cannot be 
    imported as reformulated, and the importers only option is to import 
    the gasoline as conventional. Moreover, the importer cannot import the 
    gasoline as reformulated and subsequently add blendstock to reduce the 
    benzene content, and the gasoline cannot be imported as conventional 
    and converted to reformulated subsequent to remedial blending. The 
    financial consequences to an importer of downgrading a shipload of 
    gasoline from reformulated to conventional could be significant.
        This constraint on imported gasoline does not apply in the case of 
    a refinery where gasoline is produced that is off-spec. Consider a 
    refiner who produces a batch of reformulated or conventional gasoline 
    and who determines that the gasoline is off-spec prior to the gasoline 
    leaving the refinery or being fungibly mixed at the refinery. The 
    refiner can delay designating the gasoline as a batch of RFG, reblend 
    the batch to correct the off-spec condition, and designate the 
    reblended gasoline as a batch for refinery compliance calculations.
        EPA is proposing changes that would allow importers to treat 
    imported conventional or reformulated gasoline as blendstocks (termed 
    ``gasoline treated as blendstock,'' or ``GTAB'') in order to conduct 
    remedial blending of off-spec imported gasoline. An importer's ability 
    to classify imported gasoline as GTAB would be subject to significant 
    conditions and constraints, however, that are included in the proposed 
    regulations. For example, the GTAB could not be sold or transferred by 
    the importer to another company prior to the completion of remedial 
    blending. As a result, the company that imports the gasoline and 
    classifies it as GTAB in its importer capacity also would be required 
    to conduct remedial blending and report the blended gasoline in its 
    refiner capacity. This proposed constraint is included in order to 
    curtail any commerce in gasoline that has not been certified. EPA is 
    concerned that in the absence of this constraint gasoline could be lost 
    in the fungible distribution system without ever having been certified.
        In addition, for standards that are based on a company's individual 
    baseline (such as the standards for sulfur, T-90 and olefins for simple 
    model reformulated gasoline, and all conventional gasoline standards) 
    the company would be required each year to calculate an adjusted 
    refinery compliance baseline for the refinery where the GTAB is used to 
    produce gasoline. This adjusted compliance baseline would be calculated 
    separately each calendar year averaging period when GTAB is used to 
    produce gasoline, and would consist of the volume-weighted combination 
    of the company's importer baseline at the GTAB volume for the year, and 
    the refinery's individual baseline at refinery's gasoline volume 
    exclusive of GTAB for the year. This proposed condition is intended to 
    prevent a company with an individual refinery baseline that is less 
    stringent than the company's importer baseline from using the GTAB 
    option as a device to apply the less stringent refinery baseline to 
    imported gasoline.
        EPA has previously allowed use of this GTAB option in guidance 
    included in Reformulated Gasoline and Anti-Dumping Questions and 
    Answers (February 6, 1995). EPA experience since this guidance was 
    issued has been that the GTAB option has been effective in providing 
    importers appropriate flexibility to correct off-spec imported 
    gasoline, and that the conditions and limitations have been effective 
    in preventing compliance difficulties.
    
    D. Treatment of Interface and Transmix (Proposed Sec. 80.84)
    
        When refined petroleum products are transported by pipeline the 
    products normally are pumped sequentially, but as a continuous flow, 
    through the pipeline. Thus, for example, the products in a pipeline may 
    consist of the following in sequence: Premium conventional gasoline, 
    regular conventional gasoline, premium reformulated gasoline, regular 
    reformulated gasoline, diesel fuel, number 2 heating oil, jet fuel, 
    etc. Where there is no mechanical separation of the product types in 
    the pipeline, and normally there is none, some mixing of adjacent 
    product types occurs. While the magnitude of this mixing typically is 
    small, there nevertheless is some amount of mixing.
        The petroleum product in a pipeline between two surrounding batches 
    of petroleum product that consists of a mixture of the two surrounding 
    batches is called ``interface.'' Where interface product consists of a 
    mixture of gasoline and distillate (e.g., diesel fuel, heating
    
    [[Page 37361]]
    
    oil, or jet fuel), the interface is called ``transmix.''
        It is EPA's understanding that historic pipeline industry practice 
    regarding interface has been to blend the interface mixture into the 
    two adjoining products that created the interface. Thus, for example, 
    half of the interface between premium and regular gasoline is blended 
    into the premium gasoline and half into the regular gasoline--called a 
    ``fifty percent cut'' or a ``mid-point cut.'' EPA further understands 
    that certain product types are not mixed with any other product type, 
    such as jet fuel. As a result, for example, where there is an interface 
    between jet fuel and heating oil, none of the interface is blended into 
    the jet fuel, and all of the interface is blended into the heating 
    oil--called a ``clean cut.''
        Lastly, EPA understands that certain types of interface mixtures 
    cannot easily be blended into either of the adjoining products. This 
    would be the case where interface consists of a mixture of gasoline and 
    distillate, commonly called ``transmix.'' EPA's understanding is that 
    the current pipeline industry practice, when possible, is to transmit 
    transmix via pipeline or barge to a facility designed to separate the 
    gasoline and distillate portions--a ``transmix processing'' facility. 
    Where transmix cannot be transported to a transmix processing facility 
    the transmix is blended into gasoline in very small amounts, typically 
    0.25% to 0.5% of the gasoline by volume.
        Under 40 CFR 80.78(a) parties are required to segregate certain 
    categories of gasoline. For example, 40 CFR 80.78(a)(10) states that 
    ``(n)o person may combine any reformulated gasoline with any 
    conventional gasoline and sell the resulting mixture as reformulated 
    gasoline.'' Thus, in order to sell gasoline as reformulated the 
    gasoline cannot have been mixed with any conventional gasoline.
        Under 40 CFR 80.2 (h) and (i), 80.65(a), and 80.101 the 
    reformulated gasoline and antidumping requirements apply at any 
    facility where gasoline is produced. Gasoline most commonly is produced 
    at refineries where crude oil is processed into blending components, 
    that are then combined to create gasoline. Gasoline also is produced at 
    any other location where blendstocks are combined to create gasoline, 
    or where blendstocks are added to gasoline to create additional 
    gasoline volume. Moreover, EPA believes that gasoline is produced when 
    transmix is separated into gasoline and distillate portions.
        EPA now is proposing regulations that would clarify the manner in 
    which interface product, including transmix, would be treated under the 
    reformulated gasoline program.
        The proposed regulations contain requirements for transmix 
    processors (parties who separate transmix into diesel and gasoline), 
    and transmix blenders (parties who blend transmix into gasoline without 
    first separating it into diesel and gasoline). Further, the 
    requirements for transmix processors and blenders would be different 
    depending upon whether the gasoline produced or blended is reformulated 
    or conventional gasoline.
        Transmix processors who classify the gasoline produced as 
    conventional would be required to exclude this transmix-based product 
    from anti-dumping compliance calculations. If the transmix processor 
    used blendstocks other than the transmix-based product, however, the 
    processor would be classified as a refiner and would have to include 
    the blendstocks (but not the transmix-based product) in anti-dumping 
    compliance calculations for the refinery. This approach is being 
    proposed because the gasoline portion of the transmix would have been 
    included in the compliance calculations of the refinery that produced 
    the gasoline, and for the transmix processor also to include the 
    gasoline would result in double-counting. Any blendstock used in the 
    operation normally would not previously have been accounted for, 
    however, and therefore would have to be included in the transmix 
    processor's accounting.
        Transmix processors who classify the gasoline produced as 
    reformulated, in contrast, would be required to include the transmix-
    based product, as well as any other blendstocks used, in the 
    reformulated gasoline compliance calculations for the refinery. This 
    difference in treatment for reformulated gasoline produced using 
    transmix would be appropriate because it is possible the gasoline 
    produced would not meet all reformulated gasoline standards. This 
    possibility is avoided if the transmix processor were required to meet 
    all reformulated gasoline standards.
        Parties would be allowed to blend transmix into conventional 
    gasoline where certain conditions are met: (1) The transmix must result 
    from normal pipeline operations; and (2) either there must be no means 
    of transporting the transmix to a transmix processor via pipeline or 
    water, or there was a historical practice of blending transmix at the 
    facility before 1995. In addition, the rate of transmix blending would 
    be limited to the greater of 0.25% by volume, or the demonstrated 
    blending rate in 1994.
        Parties would be allowed to blend transmix into reformulated 
    gasoline under conditions that are more restrictive than are proposed 
    for conventional gasoline. The transmix would be required to result 
    from normal pipeline operations, there could be no means of 
    transporting the transmix to a transmix processor via pipeline or 
    water, and the party must be unable to blend the transmix into 
    conventional gasoline. In addition, the rate of transmix blending would 
    be limited to a maximum of 0.25% by volume. Lastly, the party would be 
    required to carry out a program of sampling and testing the 
    reformulated gasoline subsequent to transmix blending to ensure the 
    downstream standards are met, at frequencies that are included in the 
    proposed regulations.
    
    VI. Anti-Dumping Requirements
    
    A. Individual Baseline Determination (Sec. 80.91)
    
    1. Negligible Quantities (Secs. 80.91(d)(3) and 80.91(d)(5)(iii))
        The negligible quantities provision in Sec. 80.91(d)(3) was written 
    to promote simplification of baseline determination and to excuse 
    testing in certain limited circumstances. Under this provision, if a 
    refiner can show that a fuel component exists only in negligible 
    quantities in a blendstock stream, testing that stream for the 
    component in question is not required, and a value of zero is assigned 
    to that component. The fuel components to which this provision applies 
    are aromatics, olefins, benzene, sulfur, and oxygen content. Negligible 
    quantities are defined as levels which fall below the minimum levels 
    given in Sec. 80.91(d)(3). This provision is not a requirement, but 
    rather is an option designed to simplify baseline development for those 
    refiners who can and choose to take advantage of it.
        Although the negligible quantities provision was designed to 
    simplify baseline determinations, some refiners questioned the use of 
    zero values for components which existed in negligible quantities. 
    Instead, they proposed the use of the minimum values given in the 
    provision. Doing so would negate the original intention of the 
    provision to simplify baseline determinations, but it would also 
    recognize that the minimum values represent values below which the 
    components cannot be measured accurately. Although the use of the 
    minimum values would result in slightly dirtier (more lenient) 
    baselines than would result with the use of zero values, EPA is 
    proposing to revise Sec. 80.91(d)(3) to allow the use of the minimum 
    values in lieu of zero values
    
    [[Page 37362]]
    
    at the refiner's discretion. In promulgating the negligible quantities 
    provision, EPA determined that assuming a zero value relative to the 
    negligible threshold values would not significantly affect emissions. 
    The same determination applies with regard to allowing the option to 
    use the minimum values in lieu of zero values.
        The negligible quantities provision applies only to Method 3 data 
    collection for two reasons. First, the provision applies only to 
    blendstocks, not finished gasoline. Since only Method 2 and 3 data are 
    blendstock data, the provision cannot apply to Method 1 data. Second, 
    the primary action of the negligible quantities provision is to excuse 
    testing in certain cases. The only time a refiner must choose whether 
    or not to do additional testing is when considering the sufficiency of 
    its Method 3 data.
        The negligible quantities provision reduces the burden placed on 
    refiners collecting Method 3 data to satisfy the minimum data 
    requirements. If a refiner can ``show'' that a fuel component exists 
    only in negligible quantities, testing for the blendstock stream in 
    question is not required. Instead, a refiner can assume that the level 
    of a component is zero or, under today's proposal, the minimum value 
    given in Sec. 80.91(d)(3). Clearly, the showing indicates engineering 
    judgment or past experience. A showing cannot refer to actual test data 
    for the blendstock stream in question, because the very purpose of the 
    negligible quantities provision is to excuse testing. Thus if a refiner 
    has data on the stream in question, that data must be used in the 
    determination of the baseline per Sec. 80.91(d)(1)(i)(B).
        A refiner could too easily generate a fictitiously more lenient 
    baseline if EPA allowed test data to be used as a showing of negligible 
    quantities. Such a refiner could test a given blendstock stream for 
    components that are found to be essentially absent, and then lay claim 
    to the minimum values given in the negligible quantities provision. The 
    EPA has chosen to interpret the negligible quantities provision in a 
    manner that is consistent with the original intent, provides additional 
    flexibility, and yet maintains the primary goal of developing baselines 
    which accurately represent a refiner's actual 1990 production. As a 
    result, EPA is proposing to revise Sec. 80.91(d)(3) to clarify that a 
    showing under this section refers to engineering judgment or past 
    experience and not actual test data.
        One caveat on the use of actual data in the baseline determination 
    should be clarified. If a refiner measures a blendstock stream and 
    discovers that the measured component level of that stream is below the 
    applicable range for the test method used, the low end of the 
    applicable range may be substituted for the actual measured value in 
    the baseline determination. For example, if a sulfur test method has an 
    applicable range of .20-200 ppm and a blendstock stream is discovered 
    to have a sulfur content of 11 ppm with that test method, the stream 
    can be assumed to contain 20 ppm for the purposes of determining the 
    baseline. Paragraph (d)(5)(iii) has been added to Sec. 80.91 to codify 
    this allowance.
    2. Closely Integrated Facilities (Sec. 80.91(e)(1))
        Section 80.91(e)(1)(i) of the reformulated gasoline regulation 
    provides for determination of a single set of baseline fuel parameters, 
    upon petition and approval, for two or more facilities that are 
    geographically proximate to each other, yet not within a single 
    refinery gate, and whose 1990 operations were significantly 
    interconnected in 1990. While the existing provision permits EPA to set 
    a single baseline that would then apply for each of several refineries, 
    it does not permit these ``closely integrated facilities'' to be 
    grouped together for all compliance purposes (including registration, 
    recordkeeping and reporting). Rather, the provision allows a single 
    baseline to be set for each facility it represents, and Sec. 80.41(h) 
    and 80.101(h) require that each refinery comply with this baseline 
    separately, except where authorized to group refineries for compliance 
    purposes. 24 Similarly, Sec. 80.91(e)(1)(ii) permits EPA to 
    set a single baseline for a blending facility which received 75 percent 
    of its 1990 blendstock from a single refinery, or from one or more 
    refineries owned by the same refiner and that are part of an aggregate 
    baseline.
    ---------------------------------------------------------------------------
    
        \24\  Combined reports may be submitted for compliance with RFG 
    baseline-related parameters (sulfur, olefin, and T90) and anti-
    dumping. Other reports must be filed by each facility.
    ---------------------------------------------------------------------------
    
        EPA is proposing to amend the RFG and anti-dumping regulations by 
    adding Sec. 80.91(e)(1)(iii), which would require facilities that have 
    been determined to be ``closely integrated'' and granted a single 
    baseline by EPA to demonstrate compliance with all RFG and anti-dumping 
    requirements as if they were one facility. Furthermore, the ``closely 
    integrated'' facilities would have a single registration and would file 
    a single set of compliance reports. EPA believes that this change will 
    reduce costs (including paperwork costs) to industry without any 
    significant negative environmental impact.
    3. Extending the Valid Range for Sulfur in Conventional Gasoline 
    (Sec. 80.91(f)(2)(ii))
        Under the anti-dumping provisions of the final rule, refiners use 
    their individual 1990 baselines to determine compliance with the 
    regulations under both the simple and complex models. To comply with 
    the anti-dumping regulations, a refiner using the complex model is 
    subject to valid range limits for oxygen content, sulfur content, RVP, 
    E200, E300, aromatics content, olefins content, and benzene content. 
    All of these fuel parameters are represented in the complex model 
    equations applicable to conventional gasoline.
        Section 80.91(f)(2)(ii) allows a refiner to extend the conventional 
    gasoline valid range for the complex model if the benzene, aromatics, 
    or olefins values for its individual 1990 baseline fuel falls outside 
    of the valid range specified in Sec. 80.45(f)(1)(ii). This provision 
    was clarified in a Direct Final Rulemaking published on July 20, 1994 
    (59 FR 36944). At the time of this Direct Final Rulemaking, the Agency 
    had no reason to believe that provisions for the extension of the valid 
    range for fuel parameters other than benzene, aromatics, and olefins on 
    either the low or high ends were necessary. Peripheral limitations such 
    as ASTM specifications and the volatility rule were expected to 
    eliminate the need for valid range extensions in other cases. Since 
    publication of the Direct Final Rule, the Agency has determined that, 
    despite such peripheral limitations, some individual refiner baselines 
    contained sulfur levels beyond the 1000 ppm valid range limit. 
    According to the current regulatory requirements, such baseline fuels 
    cannot be evaluated with the complex model. The Agency has determined 
    that the provision for extension of the valid range limit, previously 
    applicable only to benzene, aromatics, and olefins, should also be 
    applicable to sulfur.
        By definition, the valid range limit defines that range of values 
    for a given fuel parameter within which the complex model is considered 
    accurate. Extensions of the valid range limits, therefore, cannot be 
    boundless. If the valid range limit for sulfur is extended, the refiner 
    in question must still be limited by a valid range to eliminate the 
    possibility that the complex model will be used for sulfur values that 
    are very high, which might compromise the primary objective of the 
    anti-dumping program.
        The Agency has determined that the best approach to limiting the 
    extension of the valid range for fuel benzene,
    
    [[Page 37363]]
    
    aromatics, olefins, or sulfur content is to allow target fuels to have 
    values at least up to the baseline level. Since the baseline fuel is an 
    ``average'' fuel of sorts, the Agency has also determined that refiners 
    should be given some flexibility beyond the baseline value. For sulfur 
    this flexibility will be fixed at a value of 50 ppm. Thus the extended 
    valid range limit for sulfur would be equal to the individual refiner's 
    baseline fuel value for sulfur, plus 50 ppm.
        The Agency continues to believe that the valid range limits 
    specified in Sec. 80.45(f)(1)(ii) delineate the range of fuel parameter 
    values beyond which the accuracy of the complex model is questionable. 
    Thus the Agency has determined that any extension of the specified 
    valid ranges for conventional gasoline should incorporate flat-line 
    extrapolation. Under flat-line extrapolation, the complex model 
    provides no emissions benefit or detriment when raising the value of 
    sulfur above 1000 ppm. This flat-line extrapolation will apply to both 
    the baseline fuel and any target fuels evaluated with the complex model 
    under the anti-dumping regulations.
    
    B. Anti-Dumping Standards (Sec. 80.101)
    
    1. Application of Compliance Baselines Under the Complex Model 
    (Sec. 80.101(f) (1) and (2))
        Clean Air Act section 211(k)(8), the ``anti-dumping'' section, 
    requires EPA to promulgate regulations that maintain the quality of 
    gasoline produced by each refinery, based on each refinery's 1990 
    gasoline quality, or ``baseline.'' The intent of this section is to 
    prevent refiners from shifting ``dirty'' blendstocks from RFG 
    production to conventional gasoline production. This section thereby 
    prevents the degradation in overall quality of the nation's 
    conventional gasoline as compared to gasoline quality in 1990.
        The anti-dumping regulations, at Subpart E,implement this Clean Air 
    Act section through conventional gasoline standards that are set in 
    relation to each refinery's 1990 baseline gasoline 
    quality.25 See, Sec. 80.101. However, in the case of a 
    refinery that produces a volume of gasoline during an averaging period 
    that exceeds the refinery's 1990, or baseline, volume, Sec. 80.101 
    requires that the excess volume meet anti-dumping standards that are 
    set in relation to a baseline that reflects average U.S. gasoline 
    quality in 1990, called the ``statutory'' baseline. Thus, under 
    Sec. 80.101(f) a refiner who operates a refinery with such excess 
    gasoline volume during an averaging period is required to calculate a 
    ``compliance baseline'' that adjusts the 1990 baseline to reflect the 
    excess volume over 1990 levels.
    ---------------------------------------------------------------------------
    
        \25\ The discussion in this preamble section, VI.B.1, applies to 
    importers and the gasoline imported by importers in the same way 
    that it applies to refiners and the gasoline produced at refineries, 
    but the text refers only to refiners and refineries for purposes of 
    drafting economy.
    ---------------------------------------------------------------------------
    
        The rationale for using compliance baselines is the same for both 
    simple and complex model standards. See discussion at 57 FR 13488 
    (April 16, 1992). However, under Sec. 80.101(b) compliance baselines 
    apply only to simple model standards. EPA believes the absence of a 
    requirement to use compliance baselines for complex model standards was 
    an error of omission when Sec. 80.101 was promulgated, and as a result 
    is now proposing to require use of compliance baselines under the 
    complex model.
        EPA is not proposing to require use of compliance baselines under 
    the optional complex model, even though the rationale for their use 
    would apply. The optional complex model may be used only through 1997, 
    and today's proposed changes will not become final until well into 
    1997. As a result, EPA believes it is not practical to apply compliance 
    baselines to the optional complex model at this time.
        Section 80.101(f) provides the methodology for calculating a 
    refinery's compliance baseline. Under this provision, the calculation 
    is based on a refinery's production volume of conventional gasoline, 
    reformulated gasoline, RBOB and California gasoline. However, 
    oxygenates that are blended downstream of a refinery and subsequently 
    included in the refinery's compliance calculations for conventional 
    gasoline and oxygenates added to RBOB are not currently included in the 
    calculation. EPA now believes that such oxygenates should be included 
    in a refinery's total annual production as it compares to its 1990 
    volume for the purpose of determining the refinery's compliance 
    baseline . EPA believes this change is appropriate in order to keep the 
    various provisions of Sec. 80.101 consistent.
        EPA also is proposing to change the organization of Sec. 80.101(f), 
    in order to make the requirements of this subsection clearer. This 
    reorganization would not, in itself, change the substantive 
    requirements of the subsection.
    2. Elimination of the Baseline Adjustment by Refiners Who Also Are 
    Importers (Sec. 80.101(f)(3))
        Under the anti-dumping program all domestic refineries have 
    individual baselines, while almost all imported gasoline is subject to 
    the statutory baseline. However, Sec. 80.101(f)(3) requires an importer 
    who also operates one or more refineries to use a baseline for imported 
    gasoline that is the average of the individual refinery baselines. This 
    requirement is intended to address a particular ``gaming'' concern: 
    that a refiner who operates a refinery with a stringent refinery 
    baseline (a baseline cleaner than the statutory baseline), would 
    produce conventional gasoline that would be exported and thereby would 
    be excluded from the refinery's compliance calculations, but that then 
    would be imported under the less stringent statutory baseline.
        EPA now believes the requirement at Sec. 80.101(f)(3) may be 
    unnecessary. There may be little risk of the form of gaming described 
    above, in part due to the cost of transporting large volumes of 
    gasoline out of the United States in order to be exported, and then 
    transporting the same gasoline back into the United States in order to 
    be imported. In addition, the current requirement provides a 
    competitive advantage to refiner/importers who operate refineries with 
    baselines that are dirtier than the statutory baseline. Further, EPA 
    now believes the gaming concern could be appropriately addressed by 
    simply prohibiting parties from exporting and then importing gasoline 
    for the purpose of obtaining a more favorable baseline for the 
    gasoline.
        As a result, EPA is proposing to eliminate the requirement for 
    refiner/importers to calculate a special baseline for imported 
    gasoline, and is proposing to substitute a requirement, as proposed 
    Sec. 80.101(j), that would prohibit the form of gaming described above.
    3. Compliance Calculations for Blendstocks (Sec. 80.101(g)(3))
        Under Sec. 80.101(d)(4), and subject to certain conditions, 
    refiners are allowed to include in a refinery's anti-dumping compliance 
    calculations oxygenate that is added to the gasoline produced at a 
    refinery where that oxygenate is blended at a facility downstream from 
    the refinery. 26 In the case of the simple model standards, 
    which are based only on volume-weighted parameter averages, the 
    mechanism for including an oxygenate batch in a refinery's compliance 
    calculations is straightforward--the oxygenate batch is included based 
    on its volume and
    
    [[Page 37364]]
    
    measured levels for sulfur, olefins, aromatics, etc.
    ---------------------------------------------------------------------------
    
        \26\  These conditions are aimed at ensuring that the oxygenate 
    is blended with gasoline produced at the specific refinery in whose 
    compliance calculations the oxygenate is included.
    ---------------------------------------------------------------------------
    
        However, in the case of the complex model's emissions performance 
    standards the mechanism for including oxygenates in compliance 
    calculations is less clear, because the emissions performance of an 
    oxygenate batch cannot be directly calculated using the complex model. 
    This difficulty results from the valid range limits of the complex 
    model--the complex model is valid only for fuels with parameter values 
    that are all within the valid range limits, and most oxygenates have at 
    least some parameter values that are outside these limits. For example, 
    pure ethanol has an RVP of 2.5 psi, which is less than the 6.4 psi 
    minimum valid range limit for RVP.
        Section 80.101(g)(3) includes a method for calculating the 
    emissions performance of blendstocks, including oxygenates, based on 
    the difference in emissions performance between a baseline gasoline, 
    and the emissions performance of a hypothetical blend of baseline 
    gasoline and an appropriate amount of the applicable blendstock. 
    However, the Sec. 80.101(g)(3) method is of limited use in that it only 
    applies for refineries that only produce gasoline by adding blendstocks 
    to finished gasoline at a single facility. It has been brought to EPA's 
    attention that in the case of a refinery that also includes gasoline 
    batches in its compliance calculations this method is not appropriate. 
    27 As a result, EPA is proposing to modify the 
    Sec. 80.101(g)(3) method in order that blendstock batches may be 
    included in compliance calculations along with gasoline batches. 
    28
    ---------------------------------------------------------------------------
    
        \27\  Under the Sec. 80.101(g)(3) method a refiner calculates, 
    for each blendstock batch, the amount the emissions performance that 
    the batch differs from the refinery's baseline; the net difference 
    for all blendstock batches used during an averaging period must be 
    zero. In effect, the blendstock batches constitute a separate 
    averaging ``pool'' for compliance calculation purposes, that is not 
    merged with the compliance calculations for a refinery's gasoline 
    batches. As a result, for example, the Sec. 80.101(g)(3) method 
    would not allow a refiner to use the relatively ``clean'' emissions 
    performance of ethanol blended with a refinery's gasoline at a 
    downstream terminal, to help meet standards by gasoline produced at 
    the refinery.
        \28\ The proposed compliance calculation method involving 
    previously certified gasoline (PCG), discussed in Preamble Section 
    IV.C.6., also would be available to a conventional gasoline refiner. 
    Under the PCG proposal a refinery's compliance would be based only 
    on the volume and properties of blendstocks that are blended by 
    excluding the volume and properties of PCG. However, the PCG method 
    requires the refiner to sample and test each batch of gasoline 
    received, and each batch of gasoline produced, which may not be 
    feasible where oxygenate is blended at a downstream terminal.
    ---------------------------------------------------------------------------
    
        Under the proposal, a refiner would first determine the volume and 
    properties of each batch of blendstock used. This determination would 
    require the refiner to sample and test each batch of blendstock 
    received. However, in the case of oxygenates and butane the refiner 
    could use these blendstocks' normal properties instead of sampling and 
    testing each batch received, provided that the refiner completes 
    proposed procedures, discussed in Preamble sections IV.F.5 and VI.B.8, 
    that would confirm the purity of these blendstocks.
        The refiner then would determine the blending rate of the 
    blendstock. Where a blendstock batch is blended into multiple batches 
    of gasoline, the refiner could use the cumulative blending rate. For 
    example, consider a refiner who blends reformate into gasoline at a 
    terminal. 29 If this refiner receives a batch of 25,000 
    gallons of reformate, and blends this blendstock with 300,000 gallons 
    of gasoline, the blending rate would be 0.077 
    (25,000325,000=0.077). This would be true whether the 25,000 
    gallons of reformate were blended with a single 300,000 gallon gasoline 
    batch, or with six 50,000 gallon gasoline batches regardless of the 
    individual blending rates for the six batches.
    ---------------------------------------------------------------------------
    
        \29\ The terminal in this situation would be classified as a 
    ``refinery'' because gasoline volume is being produced through the 
    blending of non-oxygenate blendstocks, and the refiner would be 
    required to meet the anti-dumping standards based on the volume and 
    properties of the blendstock used at this refinery. The gasoline 
    used in the blending operation could not be included in compliance 
    calculations because it would have been previously certified.
    ---------------------------------------------------------------------------
    
        However, EPA is proposing that a blendstock batch that is used to 
    produce some gasoline that is classified as ``summer'' and other 
    gasoline that is classified as ``winter'' would have to be treated as 
    two separate batches, based on the volumes of blendstock used to 
    produce gasoline in these two ``seasonal'' categories. In addition, and 
    subject to this seasonal constraint, EPA is proposing that a refiner 
    who blends oxygenate or butane at a downstream terminal would be 
    allowed to treat as a single batch the volume of blendstock received 
    during a period of up to one month.
        Next, the refiner would calculate the properties of a hypothetical 
    gasoline, that would reflect the properties that would result if 
    gasoline having the refinery's ``summer'' or ``winter'' baseline 
    values, as appropriate, were blended with the blendstock at the 
    blending rate previously determined. These properties would be the 
    volume weighted average for each property. Although certain properties 
    such as distillation and RVP do not blend linearly, EPA is proposing 
    this approach as a reasonable approximation since there is no other 
    method to more accurately attribute the emissions effect of such 
    downstream blending operations. Consider again the example of the 
    refiner blending 25,000 gallons of reformate into 300,000 of gasoline 
    at a terminal. Assume the terminal-refinery is subject to the statutory 
    baseline, that the reformate has a benzene content of 2.10 vol%, and 
    that all of the gasoline produced using the reformate is classified as 
    ``summer.'' Under Secs. 80.91(b)(5)(i) and 80.45(b)(2) the ``summer'' 
    benzene statutory baseline is 1.53 vol%. The benzene content for the 
    hypothetical gasoline blend (Bh) would be calculated as 1.57 
    vol% using the following equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.000
    
    In the case of the calculated values for sulfur and oxygen, the 
    specific gravities of the blendstock and gasoline would be included in 
    the calculation. The measured specific gravity of the blendstock would 
    be used. However, EPA is proposing that refiners would be required to 
    use a specific gravity value of 0.749 for ``summer'' gasoline and 0.738 
    for ``winter'' gasoline, because a refiner using the proposed procedure 
    normally would not have measured the gasoline's specific gravity.
        The emissions performance of the hypothetical gasoline then would 
    be determined using the complex model. Under the complex model, these 
    are the exhaust toxics and NOX emissions performance, in mg/
    mi. Like for other compliance calculations involving the complex model, 
    the ``summer'' complex model would be used for gasoline blends that are 
    intended for use in an area subject to an EPA summertime RVP standard 
    at a time these standards are in effect, and that has an RVP value that 
    meets this standard. The emissions performance for all other gasoline 
    blends would be determined using the ``winter'' complex model.
        In addition, the refiner would determine the emissions performance 
    of a gasoline having the refinery's baseline values, using the same 
    complex model version--``summer'' or ``winter''--that was used to 
    calculate the emissions performance of the hypothetical gasoline.
        Finally, EPA is proposing an equation that would be used to 
    calculate the emissions performance of the blendstock portion of the 
    hypothetical gasoline blend, called the ``equivalent emissions 
    performance.'' The equivalent emissions performance values for the 
    blendstock, together with the blendstock
    
    [[Page 37365]]
    
    volume, would be included in the refinery's compliance calculations as 
    a separate batch.
        Consider again the example of the terminal-refiner using reformate, 
    and assume the hypothetical gasoline blend, when evaluated under the 
    summer complex model, had a NOX emissions performance of 
    685.6 mg/mi. Using the summer baseline emissions performance for 
    NOX under Sec. 80.45(b)(3) (660.0 mg/mi) and the blendstock 
    volume fraction previously calculated (0.077), the blendstock's 
    NOX equivalent emissions performance (EEP) would be 
    calculated to be 353.13 mg/mi using the following equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.001
    
        The refiner in this example would include in the refinery's annual 
    NOX emissions performance compliance calculations a batch 
    with a volume of 25,000 gallons (the blendstock volume), and a 
    NOX emissions performance of 353.13 mg/mi.
        EPA is proposing that these changes to the blendstock calculation 
    method would be effective beginning January 1, 1998. As a result, any 
    refiner who has elected to use the early complex model and who combines 
    blendstock with previously certified gasoline during the 1997 averaging 
    period would use the current calculation method in Sec. 80.101(g)(3). 
    EPA believes this proposed timing is appropriate because it avoids the 
    confusion and difficulties of reporting that would result if refiners 
    used two different calculation methods during the same averaging 
    period.
        EPA also is proposing to change the organization of Sec. 80.101(g), 
    in order to make the requirements of this subsection clearer. This 
    reorganization would not, in itself, change the substantive 
    requirements of the subsection.
        4. Classifying Gasoline as Summer or Winter Gasoline
    (Delete Secs. 80.101(g) (5) and (6); Proposed Sec. 80.101(g)(3)(ii))
        Refiners and importers who are subject to complex model standards 
    are required to determine the emissions performance of each batch of 
    gasoline using the ``summer'' or ``winter'' version of the complex 
    model, as appropriate. Sections 80.101(g) (5) and (6) currently provide 
    instructions for classifying gasoline as either summer or winter, based 
    on the RVP of the gasoline. Gasoline with an RVP value that is less 
    than the value required under the volatility regulations at Sec. 80.27 
    must be classified as summer gasoline, and all other gasoline must be 
    classified as winter gasoline. No other criteria is included in the 
    regulations.
        Separate summer and winter complex models are included in the 
    regulations in order to address the seasonal factors that influence 
    emission levels.30 As a result, the summer complex model is 
    appropriate for determining the emissions only for gasoline used during 
    the summer, which generally corresponds to the high ozone season, and 
    the winter complex model is appropriate for determining the emissions 
    only for gasoline used outside the summer. In consequence, EPA believes 
    the criteria for classifying gasoline as summer versus winter should 
    include the season when the gasoline is used, and not only the RVP of 
    the gasoline.
    ---------------------------------------------------------------------------
    
        \30\ The principal difference between the summer and the winter 
    complex models is that the summer model includes evaporative 
    emissions, while the winter complex model does not. Evaporative 
    emissions largely are a function of ambient temperatures.
    ---------------------------------------------------------------------------
    
        Another issue regarding the appropriate seasonal complex model 
    involves gasoline used outside the continental United States in areas 
    such as Alaska, Hawaii, Puerto Rico and the Virgin Islands. Gasoline is 
    classified as summer gasoline for baseline purposes, under 
    Sec. 80.91(d)(1)(i)(A)(1), only when the gasoline is ``produced and 
    intended for sale to satisfy federal summer volatility standards.'' The 
    federal summer volatility standards, in Sec. 80.27, apply only to 
    gasoline used in the continental United States. As a result, the 
    emissions of all gasoline used outside the continental United States 
    were calculated using the winter complex model for baseline purposes.
        The anti-dumping standards are based on a comparison of the 
    emissions of a refinery's gasoline during an averaging period with the 
    refinery's baseline emissions. This comparison is valid only if the 
    same criteria are used in the baseline and in the averaging period for 
    classifying gasoline as summer or winter.
        As a result, under proposed Sec. 80.101(g)(3)(ii), gasoline would 
    be classified as summer gasoline only where the gasoline both meets a 
    federal RVP standard under Sec. 80.27, and is intended for use in an 
    area subject to the RVP standards during the period these standards are 
    in effect. Thus, all gasoline produced for use in the continental 
    United States between May 1 and September 15 each year would be 
    classified as summer gasoline. In addition, any low RVP gasoline 
    produced before May that is intended to ``blend-down'' the RVP of 
    gasoline storage tanks in advance of the RVP season also would be 
    classified as summer gasoline. Lastly, all gasoline produced for use 
    outside the continental United States, where the federal RVP standards 
    do not apply, would be classified as winter gasoline year-round.
    5. Adjustment and Aggregation of Refineries That Exchange Ownership and 
    That Are Not Wholly Owned (Sec. 80.101(h))
        Section 80.101(h) provides that refiners who operate more than one 
    refinery may aggregate their refineries for purposes of achieving 
    compliance with the anti-dumping standards. However, the regulations 
    include no instructions regarding whether a refiner may aggregate a 
    refinery that is operated by more than one refiner. EPA is concerned 
    that enforcement difficulties could result if refiners were allowed 
    aggregation of refineries with joint owners. Consider for example, 
    hypothetical refinery 1, that is jointly owned by refiners A and B and 
    hypothetical refinery 2 that is jointly owned by refiners A and C. In 
    this example, refineries 1 and 2 are aggregated and these aggregated 
    refineries fail to meet the anti-dumping standards. In this situation 
    both refiners B and C could argue that the violation occurred as a 
    result of actions that occurred at a refinery with which they were not 
    involved and consequently should not be liable. In consequence, it 
    would be difficult to establish the liable party in such a situation.
        As a result, EPA believes that aggregation should be available only 
    for refineries with a single person who meets the definition of 
    ``refiner'' for the refinery, or where the persons who meet the 
    definition of refiner for multiple refineries are identical, and is 
    proposing to require this aggregation condition.
        Section 80.91(f)(4) provides instructions regarding the adjustment 
    of aggregate baselines where a refinery that is part of an aggregation 
    is shut down or is transferred to another owner. This section provides 
    that where an aggregated refinery is shut down or transferred the 
    baseline is recalculated to reflect the loss of the shut down or 
    transferred refinery, and where a refinery is acquired the acquiring 
    refiner must make an aggregation election regarding the acquired 
    refinery. However, there are no parallel instructions in Sec. 80.101(h) 
    regarding compliance for an aggregated refinery that is shut down or 
    transferred.
        EPA believes the baseline requirements and the compliance 
    requirements regarding aggregated refineries should be consistent.
    
    [[Page 37366]]
    
    Therefore, EPA is proposing to adopt for compliance purposes the 
    instructions in Sec. 80.91(f)(4). In addition, EPA is proposing to 
    require that when a refinery is transferred during the course of an 
    averaging period that each refiner would be responsible for meeting 
    applicable standards during the period it was the refiner for the 
    refinery. EPA also is proposing that the aggregation election for an 
    acquired refinery would have to be made effective at the beginning of 
    the subsequent averaging period. This timing proposal would minimize 
    the number of refineries that could be part of different aggregations 
    during a single averaging period, and the confusion and enforcement 
    difficulties that result from such a situation.
    6. Elimination of Composite Sampling and the Inclusion of Sample 
    Retention Requirements (Current Sec. 80.101(i)(2); Proposed 
    Sec. 80.101(i)(1)(iii))
        Section 80.101(i), in general, requires that refiners and importers 
    sample and test every batch of conventional gasoline, and under certain 
    circumstances blendstocks used to produce conventional gasoline, for 
    the purpose of demonstrating compliance with the requirements of this 
    subpart. For the purpose of meeting this requirement, refiners and 
    importers currently may combine samples from more than one batch of 
    gasoline for testing purposes in accordance with the specified 
    protocols under Sec. 80.101(i)(2). It was EPA's initial belief that 
    since this procedure was permitted for the development of baseline 
    data, it would be appropriate for demonstrating compliance.
        EPA now is concerned that composite sampling may not provide the 
    accurate results necessary for measuring compliance by refiners and 
    importers under the anti-dumping program, and may also pose significant 
    risk with regard to the enforcement and assurance of compliance. EPA's 
    primary concern is that the accuracy of composite sampling relies on 
    accurate volumetric proportioning and blending of individual batch 
    samples. Since these normally will be relatively small volumes of 
    gasoline, there is a substantial potential for inaccurate proportioning 
    and blending. For example, one refiner commented to the Agency that the 
    current compositing option has the potential for causing inconsistent 
    lab results. EPA now believes this is a difficult process to complete 
    accurately. Equally significant is EPA's concern that the volume 
    fractions can readily be altered, either intentionally or 
    inadvertently, with little or no backup means for EPA to detect or 
    verify such alterations. Such alterations would render the reported 
    analyses invalid thus providing little or no assurance of compliance 
    with this subpart by regulated parties.
        Further, compositing of samples has the potential to expand the 
    effect of any errors in formulating or testing a composite sample. 
    Compliance with the conventional gasoline standards is calculated using 
    sample test results weighted for the volume of gasoline represented by 
    the sample. As a result, any incorrect test result for a composite 
    sample would apply to the entire volume of gasoline represented by the 
    composite sample, which could be all gasoline produced during a month, 
    and not just to the volume of a single gasoline batch.
        For the above reasons, EPA believes that composite sampling and 
    analysis as provided under Sec. 80.101(i)(2) is inappropriate. 
    Therefore, EPA is proposing to eliminate the sample compositing option 
    under Sec. 80.101(i)(2). EPA's objective in this proposal is to provide 
    certainty of the accuracy of reports of conventional gasoline quality 
    that generally are comparable to the certainty that results from per 
    batch testing. EPA seeks comments on the cost of this proposal and 
    other options that would achieve this objective at a reduced burden to 
    regulated parties.
        One alternative option would be to require every-batch testing for 
    certain parameters, and to allow parties to use composite samples for 
    other parameters. In order to evaluate this alternative option, EPA 
    seeks comments on which parameters parties normally test on an every 
    batch basis, whether for operational or commercial purposes. In 
    addition, EPA requests comment on any cost savings that would result 
    from this option as compared to testing all parameters for every batch.
        Another alternative option would allow compositing, but with a cap 
    on the volume of gasoline that could be included in any composite 
    sample. The objective of this alternative option would be to mitigate 
    the cost of sampling and testing for refiners, typically small 
    refiners, who produce a large number of very small batches. As a 
    result, the volume cap could be set at the typical batch size for a 
    typical refinery. EPA requests comment on the magnitude of the volume 
    cap that would be appropriate under this alternative option, and on the 
    cost savings that would result from this option as compared to every-
    batch testing.
        In addition, EPA is concerned that since there is no independent 
    verification of the accuracy of test results of individual batches of 
    gasoline, EPA has a very limited ability to monitor compliance with the 
    conventional gasoline requirements. Although the independent sampling 
    and testing requirement of the reformulated gasoline program is 
    critical to ensuring compliance with the stringent RFG standards, the 
    same requirement may be excessive for the anti-dumping program. 
    However, EPA believes some limited ability to verify the accuracy of 
    sample analysis results is appropriate as a means of encouraging 
    quality control and monitoring compliance as a deterrent to cheating.
        Therefore, EPA is proposing a new requirement under 
    Sec. 80.101(i)(1)(iii) that refiners and importers retain samples from 
    each batch of conventional gasoline produced or imported for a period 
    of 30 days and provide such samples to EPA upon request. EPA would plan 
    to periodically request samples from individual refiners, either on a 
    random basis or when it has reason to be suspect, in order to perform 
    its own gasoline quality analyses. This requirement would apply to 
    conventional gasoline, gasoline blendstocks that become conventional 
    gasoline solely upon the addition of oxygenate and blendstocks required 
    for compliance calculations purposes under Sec. 80.102(e)(2). The 
    sample retention requirement would not apply to oxygenates blended 
    downstream of the refinery or import facility. The Agency believes that 
    refiners and importers often retain samples for some period for their 
    own internal quality control purposes and, as a result, this 
    requirement will not create a significantly increased burden for the 
    industry. EPA seeks comments on the cost or other impacts of this 
    proposal. In addition, EPA seeks comment on the cost savings that would 
    result if the required retention period were reduced to 15 days.
        EPA recognizes that some refiners blend conventional gasoline ``in-
    line'' and ship directly to the pipeline without transferring completed 
    batches to a storage tank. In this case, sampling in-line using a 
    ``compositing'' methodology as the batch is being produced is the only 
    practical means to obtain a representative sample from such batches. 
    Today's proposal to eliminate composite sampling of multiple batches 
    would allow continued use of in-line blend compositing within a batch. 
    Further, EPA does not intend to establish any formal means of 
    petitioning for conventional gasoline in-line blending as currently 
    exists for reformulated gasoline blending. Therefore, EPA believes that 
    refiners
    
    [[Page 37367]]
    
    that blend in-line, without transferring the final blend to a storage 
    tank, should continue to composite in-line provided they do so in 
    accordance with the industry established automatic sampling procedures 
    established by ASTM D 4177-95, ``Standard Practice for Automatic 
    Sampling of Petroleum and Petroleum Products''. The manual compositing 
    of samples from an in-line blender creates the same quality and 
    compliance concerns discussed earlier. Further, EPA believes the 
    automatic sampling requirements proposed under Sec. 80.8(b), and as 
    referenced in proposed Sec. 80.47 and revised Sec. 80.101, already 
    establish the procedures required for refiners in order to continue in-
    line blending of conventional gasoline.
        One of the issues surrounding the elimination of compositing as a 
    method for compliance verification by conventional gasoline producers 
    is the cost of the additional testing. EPA recognizes that the cost of 
    meeting the additional testing requirements by using an outside 
    laboratory may pose a significant expense for some refineries and, 
    therefore, it would be preferable if refiners could meet their testing 
    requirements internally. Based on the results of recent refinery 
    compliance monitoring since the beginning of the RFG/Anti-dumping 
    program, EPA believes that most refiners have equipment required to 
    perform the regulatory tests at their refinery except for sulfur under 
    the current regulatory test method ASTM D 2622. In an effort to 
    minimize the potential cost of the additional testing required through 
    the proposed elimination of sample compositing, EPA examined cost 
    effective alternative test methods to ASTM D 2622 available for 
    determining sulfur content in conventional gasoline. EPA has observed 
    data that suggests that ASTM D 5453-93 (``Standard Test Method for 
    Determination of Total Sulfur in Light Hydrocarbons, Motor Fuels and 
    Oils by Ultraviolet Fluorescence''), when properly calibrated and 
    correlated to ASTM D 2622, can be used on gasoline samples containing 
    sulfur in the range typical of commercial gasoline. EPA is, therefore, 
    proposing that ASTM D 5453-93 be allowed as an alternative test method 
    for determining sulfur content in conventional gasoline only until 
    September 1, 1998. This date is being proposed based on EPA's 
    anticipated completion of a performance based test method rulemaking as 
    discussed at 61 FR 58305, November 13, 1996. EPA requests comment on 
    the cost of this equipment and whether this method provides sulfur test 
    results comparable to the current regulatory method.
    7. Imports of Gasoline From Canada by Truck (Sec. 80.101(i)(3))
        Under 40 CFR 80.65 (b) and (c), and 80.101(d) and (i), the 
    requirements that apply to imported gasoline apply to each batch of 
    imported gasoline regardless of the mode of transportation. The 
    requirements for each batch include sampling and testing, independent 
    sampling and testing for reformulated gasoline, record keeping, 
    reporting and attest engagements. Thus, an importer who imports 
    gasoline into the United States by truck is required to meet these 
    requirements, including sampling and testing, for each gasoline batch, 
    and in such a situation a batch would consist of the gasoline contained 
    in the truck if homogeneous or in each truck compartment if the truck's 
    gasoline is not homogeneous.
        EPA understands that the every-batch requirements may be difficult 
    to meet when gasoline is imported by truck, because of the relatively 
    small batch volumes. As a result, EPA is proposing a limited 
    alternative method by which certain importers could meet the 
    requirements for conventional gasoline that is imported into the United 
    States via truck. This proposed approach would be limited to imported 
    conventional gasoline, and would not apply in the case of imported 
    reformulated gasoline, because of the additional level of environmental 
    concern associated with reformulated gasoline.
        This proposed approach would be based on the importer meeting the 
    conventional gasoline standards on a per-gallon basis, which is 
    different than the normal approach of meeting conventional gasoline 
    standards on average. Per-gallon compliance is being proposed because 
    under this proposal the importer would not be required to sample and 
    test each truck load--each batch--of imported gasoline, which is 
    necessary in order to demonstrate compliance with a standard on 
    average. Rather, the importer would be allowed to rely on sampling and 
    testing conducted by the operator of the truck loading terminal in 
    Canada or Mexico to verify that the gasoline meets all conventional 
    gasoline standards that apply to the importer.
        For example, if an importer's gasoline is subject to the statutory 
    baseline set out at Sec. 80.91(c)(5), under the simple model the 
    standards for imported conventional gasoline, specified at 
    Sec. 80.101(b)(1), are the following: sulfur--422.5 ppm; T90--415 
    deg.F; olefins--13.5 vol%; and exhaust benzene emissions--6.45. Under 
    Sec. 80.101(a) these conventional gasoline standards are met on average 
    over each calendar year averaging period. If this importer elected to 
    import gasoline via truck under the proposed approach, however, the 
    importer would be required to demonstrate that each gallon of this 
    gasoline met each of these standards. The environmental consequences of 
    this proposal would be neutral, because by meeting the average standard 
    on an every-gallon basis the standard also is being met on average.
        The proposal also includes the means by which the importer would be 
    required to demonstrate the gasoline meets the applicable standards on 
    an every-gallon basis. The gasoline in the storage tank from which the 
    importer's trucks are loaded would have to be sampled and tested 
    subsequent to each receipt of gasoline, and these tests would have to 
    show the gasoline meets the applicable standards. This sampling and 
    testing could be conducted by the terminal operator. For each truck 
    load of imported gasoline the importer would have to obtain from the 
    terminal operator documents that state the properties of the gasoline. 
    The importer then would treat each truck load of imported conventional 
    gasoline as a separate batch for purposes of the record keeping and 
    reporting requirements.
        The terminal operator in most cases would not be subject to United 
    States laws, so the proposal contains safeguards that are intended to 
    ensure the gasoline in fact meets the applicable standards. First, the 
    importer would be required to conduct an independent program of quality 
    assurance sampling and testing of the gasoline dispensed to the 
    importer. This sampling and testing would have to be at a rate 
    specified in the proposed regulations, and the sampling would have to 
    be unannounced to the terminal operator. In addition, EPA inspectors 
    would have to be given access to conduct inspections at the truck 
    loading terminal and at any laboratory where samples collected pursuant 
    to this proposed approach are analyzed. These inspections could be 
    unannounced, and would include sampling and testing, and record 
    reviews.
        EPA previously has allowed conventional gasoline to be imported by 
    truck in a manner that essentially is identical to the option now being 
    proposed, in guidance included in Reformulated Gasoline and Anti-
    Dumping Questions and Answers (October 29, 1994). EPA's experience 
    since this guidance was issued has been that the approach facilitates 
    imports of conventional gasoline by truck, and that
    
    [[Page 37368]]
    
    the sampling and testing requirements are appropriate enforcement 
    safeguards.
        EPA requests comment on this proposed approach for parties who 
    import conventional gasoline via truck. In particular, EPA requests 
    comment of the proposed provisions that deal with requirements that 
    apply to persons located outside the United States, and to the need for 
    EPA inspectors to conduct inspections at terminals located outside the 
    United States.
    8. Butane Blending Issue (Sec. 80.101(i)(4))
        The addition of blendstock, including butane, to reformulated or 
    conventional gasoline constitutes the production of gasoline, with the 
    result that such a blender is considered a refiner under the 
    reformulated and conventional gasoline regulations, who is subject to 
    all standards and requirements that apply to refiners. These 
    requirements include meeting the standards applicable to reformulated 
    and conventional gasoline, sampling and testing, record keeping, and 
    reporting. Under Secs. 80.65(i) and 80.101(e)(1) the reformulated or 
    conventional gasoline with which the blendstock is blended must be 
    excluded from the blender-refiner's compliance calculations. In effect, 
    the reformulated and conventional gasoline standards must be met based 
    on the blendstock properties alone. Under Sec. 80.101(i)(1)(i), 
    refiners who produce conventional gasoline by combining blendstock with 
    previously-certified conventional gasoline may determine compliance 
    with the anti-dumping standards by sampling and testing the blendstock 
    following each receipt of blendstock.
        EPA understands that butane is a blendstock that historically has 
    been blended with gasoline, particularly in the wintertime. This butane 
    blending occurs in part because butane increases the volatility of 
    gasoline, and the commercial specifications for wintertime gasoline 
    allows (or requires) higher volatility levels than for summertime 
    gasoline. In addition, there are economic reasons for blending butane, 
    because butane generally costs less than gasoline. Butane generally is 
    not blended with gasoline that will be used during the high ozone 
    season (May 1 through September 15), because the increased volatility 
    of gasoline blended with butane could violate the federal or state 
    volatility standards that apply during that period.
        EPA understands that a significant impediment to blending butane 
    into gasoline outside the high ozone season is the requirement that 
    refiners must sample each batch of conventional or reformulated 
    gasoline produced, or in the case of conventional gasoline sampling 
    each batch of blendstock. This sampling requirement interferes with 
    butane blending because butane typically arrives at blend terminals, 
    and is blended in relatively small quantities. As a result, a butane 
    blending operation would be required to sample at a frequency that 
    could be restrictive for some parties.
        In the case of butane blending into conventional gasoline that 
    occurs outside the high ozone season, EPA believes there may be little 
    adverse environmental impact provided that the butane is of sufficient 
    purity, and that much of the butane used for blending with gasoline is 
    of such purity. However, ozone is of environmental concern during the 
    ``shoulder'' periods immediately preceding and immediately following 
    the high ozone season, and the increased RVP from butane that is 
    blended during the shoulder periods may cause adverse environmental 
    impacts particularly in ozone non-attainment areas.
        Nevertheless, EPA is proposing an alternative sampling and testing 
    option that would be available to parties who blend butane into 
    conventional gasoline that is used outside the high ozone season. Under 
    this proposed option a party who blends butane into conventional 
    gasoline would continue to be classified as a refiner, and would be 
    liable for all refiner requirements. However, the blender would have an 
    additional sampling and testing option. The blender-refiner would be 
    able to demonstrate compliance with the conventional gasoline standards 
    on the basis of the butane specifications provided by the butane 
    supplier, subject to certain conditions that are specified in the 
    proposed regulations.
        EPA is not proposing that parties who blend butane into RFG would 
    be able to use this relaxed approach to sampling and testing because of 
    concern for adverse environmental impacts during the shoulder periods. 
    If butane blending with RFG were made more convenient, as is proposed 
    for conventional gasoline, an increase in the volatility of RFG during 
    the high ozone season's shoulder periods could result.
        EPA requests comment on the potential for adverse environmental 
    effects from butane blending with conventional gasoline during the 
    shoulder periods, particularly at terminals serving non-RFG ozone non-
    attainment areas, and whether any such potential would be reason for 
    EPA to decline to promulgate the proposed regulatory changes to 
    facilitate butane blending with conventional gasoline. In particular, 
    EPA requests comment on whether the flexibility for butane blending 
    with conventional gasoline should be limited to terminals serving areas 
    that are in attainment for ozone, which would be consistent with the 
    decision to not propose change to facilitate butane blending with RFG. 
    In addition, EPA requests comment on whether butane blending with 
    conventional gasoline should be facilitated only during a period that 
    is outside the high ozone season plus a shoulder period--for example, 
    between October 15 through March 31 each year.
        EPA previously has allowed butane blending in a manner that 
    essentially is identical to the option now being proposed, in guidance 
    included in Reformulated Gasoline and Anti-Dumping Questions and 
    Answers (October 3, 1994). EPA's experience since this guidance was 
    issued has been that the approach facilitates butane blending with 
    conventional gasoline, and that certification mechanisms are 
    appropriate.
        EPA requests comment on this proposal to relax the sampling and 
    testing associated with blending butane with conventional gasoline. In 
    addition, EPA requests comment on the proposal that this additional 
    flexibility not be extended to butane blending with reformulated 
    gasoline.
    
    C. Controls Applicable to Blendstocks (Sec. 80.102)
    
        Under the anti-dumping program refiners are required to track the 
    volume of certain blendstocks produced and transferred to others and to 
    include blendstocks in their compliance calculations if the blendstock 
    volume exceeds certain thresholds. The purpose of these blendstock 
    requirements is to prevent a particular form of ``gaming'': 
    transferring blendstock produced at a refinery with a baseline more 
    stringent than the statutory baseline to a refinery with the statutory 
    baseline to be blended into gasoline in order that the blendstock would 
    be subject to more lenient standards. See the discussion at 59 FR 7801 
    (February 16, 1994).
        As a result of comments received from industry since the anti-
    dumping program began, EPA now is proposing several modifications to 
    the blendstock tracking and accounting requirements.
    1. Blendstock Tracking for Refineries With the Statutory Baseline 
    (Sec. 80.102(f)(1)(i))
        Section 80.102(f)(1)(i) exempts a refinery with a baseline less 
    stringent than the statutory baseline from blendstock tracking. 
    However, the form of gaming that is the focus of blendstock tracking 
    also is not possible in the case
    
    [[Page 37369]]
    
    of a refinery with a baseline that is equal to the statutory baseline, 
    and EPA believes the omission of such refineries from the 
    Sec. 80.102(f)(1)(i) exemption was an error at the time this section 
    was promulgated. As a result, EPA is proposing to add refineries with 
    the statutory baseline to the Sec. 80.102(f)(1)(i) exemption.
    2. Products That May Be Excluded From the Blendstock Tracking 
    Requirements (Sec. 80.102(a))
        Categories of blendstock that are unlikely to be involved in the 
    blendstock gaming scenario are exempt from the blendstock tracking 
    requirements. Thus, for example, the list of applicable blendstocks 
    that must be tracked under Sec. 80.102(a) is limited to blendstocks 
    that adversely impact air quality; Sec. 80.102(d)(3) excludes from 
    blendstock tracking those blendstocks that are not likely to be used 
    for conventional gasoline blending; and Sec. 80.102(f) exempts certain 
    parties with limited blendstock production volume from blendstock 
    accounting.
        EPA now believes that the blendstock tracking requirements could be 
    further limited without jeopardizing the environmental purpose of this 
    section. The proposed changes relate to petroleum products that would 
    be unlikely candidates for conventional gasoline blending. EPA believes 
    that petroleum products with an initial boiling point less than 75 
    deg.F or an end point greater than 450  deg.F are not suitable for 
    gasoline blending and, therefore, could be excluded from the category 
    of blendstocks that refiners must track. As a result, EPA is proposing 
    to exclude products with these boiling ranges from blendstock tracking.
        EPA also now believes that certain highly refined or pure grade 
    petroleum products are unlikely to be used for gasoline blending, and 
    that these products can be identified by price or tendered volume. For 
    example, EPA believes that where a petroleum product is sold at a price 
    that is 100% above the market price of regular conventional gasoline it 
    is unlikely the purchaser will use the product for blending gasoline. 
    Similarly, EPA believes that products tendered in volumes less than 
    1,000 gallons are unlikely to be used in gasoline blending. Therefore, 
    EPA is proposing to exempt products that meet either of these criteria 
    from the blendstock tracking requirements. Further, blendstocks for 
    which the refiner has evidence are used to produce RFG need not be 
    included in the ratio calculations. EPA is proposing that such products 
    also be excluded under Sec. 80.102(d)(3).
    3. Inclusion of Products in the Blendstock to Gasoline Ratio 
    Calculations (Sec. 80.102(d) (1) and (2))
        As discussed previously under the compliance baseline calculations, 
    oxygenates added to either conventional gasoline or RBOB had been 
    previously excluded from such calculations. EPA now believes such 
    products are significant to the total volume considerations of a 
    refiner and for consistency should be included in the blendstock to 
    gasoline ratio calculations as well. EPA, therefore, is proposing in 
    Secs. 80.102(d) (1) and (2) that oxygenates blended downstream into 
    conventional gasoline under Sec. 80.101(d)(4)(ii) and oxygenates added 
    to RBOB, as determined under Sec. 80.65(e)(1)(ii), be included in the 
    denominator of the compliance year ratio calculations.
    4. Exclusion of Products From the Blendstock Accounting Requirements 
    (Sec. 80.102(d)(3)).
        Section 80.102(d)(3) exempts certain categories of petroleum 
    products from the blendstock tracking requirements, where the product's 
    use makes blendstock tracking inappropriate. For example, petroleum 
    products are exempt from blendstock tracking if the products are 
    exported, are used as a refinery feedstock, or are transferred between 
    aggregated refineries. Under Sec. 80.102(e) a party that has exceeded 
    certain blendstock volume thresholds is required to include all 
    blendstocks in its compliance calculations, and the exemptions under 
    Sec. 80.102(d)(3) are not applied.
        EPA now believes the exemptions in Sec. 80.102(d)(3) also should 
    apply to the blendstock accounting requirements, under the same 
    rationale that justifies these exclusion under blendstock tracking, and 
    is proposing this change to the blendstock accounting requirements 
    under Sec. 80.102(e).
    5. Attest Engagements Involving Aggregated Refineries (Sec. 80.102 
    Introductory Text and Secs. 80.102 (b) and (c); Subpart F)
        Section 80.101(h)(2)(iii) states that the aggregation election 
    applies to the blendstock tracking requirements, and 
    Sec. 80.102(d)(3)(iv) exempts from blendstock tracking the blendstocks 
    that are transferred between aggregated refineries. However, EPA 
    believes that for purposes of conducting attest engagements under 
    subpart F, the attest engagements should be conducted separately for 
    each refinery, but this refinery-specific approach to blendstock 
    tracking attest procedures is not clear in Sec. 80.102 or in subpart F.
        The attest requirements are organized around individual refineries, 
    and it would create unnecessary complications to require a different 
    organization only for the purpose of reviewing compliance with the 
    blendstock tracking requirements. As a result, EPA is proposing to 
    clarify the attest procedures in Subpart F to clarify that blendstock 
    tracking attest procedures must be conducted separately for each 
    refinery. In the case of aggregated refineries the blendstock tracking 
    attest procedures would be separately performed for each refinery, 
    taking into account the blendstock transfers to refineries in the same 
    aggregation. If each refinery in an aggregation separately satisfies 
    the blendstock tracking requirements, then EPA believes the aggregated 
    refineries would have satisfied these requirements overall.
    
    D. Record Keeping Requirements (Sec. 80.104)
    
        EPA is proposing to modify Sec. 80.104 to clarify that batch 
    information must be kept for oxygenate blended downstream of a refinery 
    where the oxygenate is included in the refinery's compliance 
    calculations.
        In addition, EPA is proposing record keeping requirements that 
    would apply in the case of imported GTAB, that would reflect the 
    physical movement of GTAB to the point of blending to produce gasoline. 
    (See Preamble Section V.C. concerning requirements for GTAB generally.)
    
    E. Reporting Requirements (Sec. 80.105)
    
    1. Modification of Information That Must Be Reported 
    (Sec. 80.105(a)(5)(iv))
        Section 80.105 requires refiners and importers to report various 
    information regarding each batch of conventional gasoline produced or 
    imported during the averaging period. This includes the grade of the 
    gasoline produced. Sec. 80.105(a)(5)(iv). EPA now believes it is 
    unnecessary to include this grade information in reports to EPA, and is 
    proposing to eliminate this reporting requirement.
        In addition, EPA now believes that in the case of ethanol batches 
    it is unnecessary to include the ethanol properties in the batch report 
    to EPA, because the properties of a pure compound, such as ethanol, are 
    known. Therefore, EPA is proposing to eliminate the requirement that 
    parties report the properties of ethanol.
    
    [[Page 37370]]
    
    2. Date for Submission of Attest Engagement Reports (Sec. 80.105(c))
        Section 80.105(c) requires that attest engagement reports involving 
    conventional gasoline must be submitted by May 30 each year. However, 
    Sec. 80.75(m) requires that attest engagement reports for RFG must be 
    submitted by May 31 each year. This inconsistency in reporting 
    deadlines was inadvertent when these sections were promulgated, and, as 
    a result, EPA is proposing to conform the dates by adopting May 31 as 
    the deadline for submitting conventional gasoline attest reports.
    
    VII. Attest Engagements
    
        Under Secs. 80.65(h), 80.75(m), and 80.105(c) refiners and 
    importers, and reformulated gasoline oxygenate blenders who achieve 
    compliance on average, are required to commission an audit each year to 
    review compliance with certain requirements of the reformulated 
    gasoline and anti-dumping program. The audit requirements are specified 
    in 40 CFR part 80, subpart F. Under these regulations the auditor 
    evaluates compliance with the specified requirements by completing 
    audit procedures, called ``agreed upon procedures,'' that are included 
    in the regulations for each requirement--the auditor ``attests'' to the 
    results of the agreed upon procedures. As a result, the overall audit 
    is called an ``attest engagement.''
        EPA now is proposing a number of changes to the attest engagement 
    requirements.
    1. Modified Agreed Upon Procedures (Secs. 80.128 and 80.129; Proposed 
    Secs. 80.133 and 80.134))
        The agreed upon procedures for refiners and importers are specified 
    in Sec. 80.128, and for oxygenate blenders in Sec. 80.129. In addition, 
    the headnotes of Sec. 80.128 allow parties to satisfy the attest 
    engagement requirement using other agreed upon procedures if the party 
    obtains prior approval from EPA.
        EPA received comments from industry, and from auditors who 
    conducted attest engagements under this program, that the agreed upon 
    procedures in Secs. 80.128 and 80.129 should be modified in order to be 
    more efficient. Moreover, a group of auditors who were working in this 
    area convened under the auspices of the American Institute of Certified 
    Public Accountants (AICPA) to develop new attest procedures. This group 
    submitted modified attest procedures to EPA in January 1996, and asked 
    EPA to approve these procedures for use. On March 15, 1996, EPA 
    approved use of the attest procedures AICPA submitted, with certain 
    modifications, under the authority of Sec. 80.128. EPA now is proposing 
    to include these modified attest procedures in the regulations.
        The modified attest procedures do not differ significantly in 
    substance from the procedures in Secs. 80.128 and 80.129. The principal 
    difference between the modified attest procedures and the procedures in 
    Secs. 80.128 and 80.129 is that the modified procedures includes 
    criteria for identifying when certain attest procedures, or categories 
    of attest procedures, are unnecessary for a particular attest 
    engagement. For example, attest procedures address the blendstock 
    tracking requirements under Sec. 80.102. Under Sec. 80.128, the auditor 
    is required to complete a full slate of attest procedures that 
    scrutinize each category of blendstocks relevant to the Sec. 80.102 
    requirements. Under the modified attest procedures for blendstock 
    tracking, however, the procedures are arranged in a sequence that 
    allows the auditor to identify categories of blendstock tracking attest 
    procedures that are unnecessary, and to avoid conducting these 
    procedures.
        These modified attest procedures were used successfully by numerous 
    auditors for attest engagements for the 1995 reporting period.
        The modified attest procedures also include definitions not 
    included in the original procedures, but these definitions do not 
    change the substance of the original procedures. However, in today's 
    version of the modified attest procedures, EPA is proposing a new 
    definition for ``laboratory analysis'' that would constitute a 
    substantive change.
        Under both the original and modified attest procedures, auditors 
    are required to review laboratory analysis results of various types, 
    and, inter alia, compare the results with reports to EPA. The form of 
    the laboratory analysis results that an auditor must review has not 
    been specified, however. EPA has learned that, as a result, auditors 
    often review only a company's laboratory analysis results as 
    transcribed into the computer system used to calculate compliance with 
    standards. EPA has found through its own audits of refiners and 
    importers, however, that the original laboratory results and the 
    results recorded in a computer system sometimes are different. These 
    differences often result from simple data entry errors, although on 
    occasion the reason for the difference is less benign. As a result, EPA 
    is proposing that where attest procedures call for the review of a 
    laboratory analysis result, the auditor would be required to review the 
    original laboratory result. Thus, for example, in the case of a testing 
    apparatus that generates a printout of the test results, only review of 
    this printout would satisfy an attest procedure that calls for review 
    of the laboratory result, or where test results are first recorded in 
    the chemist's laboratory log book, only review of this log book would 
    satisfy the requirement. Review of a transcribed version of these 
    original test results would not suffice.
        This proposed definition of laboratory analysis is consistent with 
    the proposed change to the record keeping requirement dealing with 
    laboratory analyses, discussed above, that requires parties to keep 
    copies of original test results.
        EPA is proposing that the original attest procedures in 
    Secs. 80.128 and 80.129 would continue to be available as alternatives 
    to the attest procedures now being proposed, but only through the 
    attest for the 1997 reporting period. Under this proposal, only the 
    attest procedures in proposed Secs. 80.133 and 80.134 could be used to 
    meet the attest engagement requirements beginning with the attest 
    engagements for the 1998 reporting period.
        EPA is proposing to phase out the original attest procedures 
    because we believe the modified attest procedures are superior, and 
    ultimately should be used for all attest engagements. In addition, EPA 
    believes oversight of the attest requirement, including reviews of 
    attest reports, would be more efficient if all attest engagements were 
    based on the same agreed upon procedures. Nevertheless, EPA requests 
    comment on whether the original attest procedures should be available 
    for use indefinitely.
        In addition, EPA is proposing that during the period when both the 
    original and the modified attest procedures are available parties would 
    be required to use either the original attest procedures for refiners 
    and importers under Sec. 80.128 in its entirety, or the modified attest 
    procedures for refiners and importers under Sec. 80.133 in its 
    entirety. A party would not be allowed to use a mixture of attest 
    procedures from Sec. 80.128 and Sec. 80.133. Similarly, an oxygenate 
    blender would be required to use the attest procedures in Sec. 80.129 
    or in Sec. 80.134, and could mix attest procedures from both sections. 
    The reason for this constraint is that the different attest procedure 
    sections contain different requirements that are organized differently, 
    and, at least in part, the logic of the sections would be lost if these 
    sections are not completed in their entirety.
    
    [[Page 37371]]
    
    2. Agreed Upon Procedure Reports (Sec. 80.130(a))
        Section 80.130 requires the CPA or CIA who conducts an attest 
    engagement to issue a report that summarizes the procedures performed 
    and findings. The regulations do not specify greater detail of what 
    must be included in an attest report, however. EPA now believes it is 
    necessary to specify certain items of information that should be 
    included in each attest engagement report. This conclusion by EPA 
    results from its review of the first attest engagement reports, for the 
    1995 reporting period, that were submitted to EPA at the end of May, 
    1996. These attest reports varied significantly in the amount of detail 
    that was included, but many reports were too scant to allow any 
    meaningful review by EPA. In fact, some attest reports stated simply 
    that the attest engagement had been conducted, and nothing more.
        The purpose of the attest engagement reports is, at least in part, 
    to enable the regulated party, and EPA, to gauge whether the attest 
    engagement was properly performed through a review of the report, and 
    in the case of findings, to put those findings into perspective 
    including whether the findings raise issues regarding compliance by the 
    refiner or importer. Where the attest report includes none of the 
    details of the procedures completed, this review is not possible. As a 
    result EPA now is proposing certain information about each attest 
    engagement that must be included in all attest engagement reports.
        Initially, EPA is proposing that attest engagement reports would 
    have to identify who conducted the attest engagement, and give a 
    telephone number of the auditor. This would allow EPA to easily contact 
    the auditor in case questions arise. In addition, the report would have 
    to identify the company and facility that was the subject of the audit.
        More substantively, attest engagement reports would be required to 
    include the volumes of gasoline, and the number of batches, ascertained 
    during the engagement in various categories. Auditors are required to 
    verify the volume and batch number information, so this information is 
    easily available to the auditor for inclusion in the report. EPA 
    believes the required volume and batch information could be included in 
    the report in the form of a simple table, which would require little 
    effort to prepare.
        In numerous instances the attest procedures require the auditor to 
    obtain listings of all documents in various categories, and to review 
    in more detail a random sampling of the documents. The procedures for 
    selecting these samples are specified in Sec. 80.127. EPA is proposing 
    that for each occasion when such a sample is selected, the audit report 
    would be required to include certain details of this sampling process, 
    including the size of the population being sampled, the size of the 
    sample selected, and the method used to ensure the sample was randomly 
    selected. Inclusion of these details would enable EPA to verify that 
    the sampling was properly completed, and to put in better perspective 
    any findings that result from the auditor's review of the sample.
    3. Attest Engagement Document Retention (Sec. 80.130(b))
        Section 80.130(b) currently requires CPAs and CIAs who conduct 
    attest engagements to retain ``all records pertaining to the 
    performance of each agreed upon procedure and pertaining to the 
    creation of the agreed upon procedures report* * *.'' EPA's normal 
    practice when conducting an enforcement audit of a refiner, importer or 
    oxygenate blender is to include an audit of the attest engagement, to 
    ensure the engagement was completed as required. These audits of attest 
    engagements require EPA to review the auditor's audit records.
        During the course of conducting these enforcement audits, however, 
    EPA discovered that many auditors retained a scant record of the 
    conduct of their attest engagements. This absence of more comprehensive 
    documentation made EPA's audits of the attest engagements more 
    difficult.
        As a result, EPA is proposing more specific regulatory requirements 
    regarding the documents that auditors would be required to retain. The 
    first category would be documents the auditor reviews that are created 
    by the company that is the subject of the attest engagement. These 
    company-created documents include laboratory analyses, inventory 
    reconciliations and product transfer documents. The second category 
    would be documents prepared by the auditor during the course of the 
    attest engagement that summarize the conduct and work product of the 
    attest engagement, commonly called ``work papers.'' The third category 
    would include computer data and/or the input, output and results of 
    computer programs used by the auditor to conduct the audit. The last 
    category would be correspondence between the auditor and the company 
    being audited on the subject of the attest engagement.
        EPA believes the proposed record retention requirements would not 
    expand the current record retention requirements, which apply to 
    ``all'' records pertaining to attest engagements. The proposed 
    requirements merely clarify that certain records are in the scope of 
    the records EPA intends that auditors should retain.
    4. Attest Procedures for GTAB (Proposed Sec. 80.131)
        EPA is proposing procedures by which importers may treat imported 
    gasoline as blendstock (``gasoline treated as blendstock'' or ``GTAB'') 
    in proposed Sec. 80.83. As a result, EPA also is proposing attest 
    procedures that would apply in the case of an importer who utilizes the 
    GTAB option. The proposed GTAB attest procedures follow the general 
    model of the attest procedures included in Secs. 80.128, 80.129, 80.133 
    and 80.140. In particular, the attest procedures proposed for GTAB 
    would instruct the auditor to track the movement of a portion of the 
    GTAB batches to ensure the movement and subsequent use of the GTAB is 
    consistent with the GTAB requirements.
    5. Attest Procedures for Refiners With In-Line Blending Waivers From 
    Independent Sampling and Testing (Sec. 80.65(f); Proposed Sec. 80.132)
        Under Sec. 80.65(f) refiners and importers of reformulated gasoline 
    are required to carry out a program of independent sampling and 
    testing, with one exception. This exception applies in the case of a 
    refiner who has obtained an EPA-approved waiver from the independent 
    sampling and testing requirements on the basis of producing 
    reformulated gasoline using an appropriately sophisticated computer-
    controlled in-line blending operation (an ``in-line blending waiver''). 
    See, Sec. 80.65(f)(4). In addition, under Sec. 80.65(f)(4)(ii) any 
    refiner with an in-line blending waiver is required to carry out an 
    independent audit of each batch produced using the in-line blending 
    operation. These audits constitute a check on the reported gasoline 
    properties for in-line blended gasoline, which is a surrogate for the 
    independent sampling and testing required for gasoline not produced 
    under an in-line blending waiver.
        The current regulations do not adequately describe the scope of in-
    line blending audits, however, and EPA is concerned that the in-line 
    blending audits refiners have conducted have not been sufficiently 
    comprehensive. As a result, EPA is proposing attest procedures that 
    would have to be
    
    [[Page 37372]]
    
    conducted for any refiner with an in-line blending waiver.
        All in-line blending waivers that EPA has granted require the 
    refiner to collect a volumetrically proportional composite sample of 
    each batch of in-line blended gasoline. This sample is collected using 
    an automatic sampling apparatus that collects a portion of the gasoline 
    being produced during the entire blending period, that is proportional 
    to the volume of gasoline being produced any time. The refiner is 
    required, by the terms of its waiver, to use the analysis of this 
    composite sample as the basis of the report to EPA of the batch 
    properties, i.e., as the ``certification'' analysis, or the ``primary 
    analysis result.''
        In-line blending waivers also require the refiner to obtain 
    secondary analysis results for each regulated parameter, for use during 
    the in-line blending audit to corroborate the primary analysis results. 
    These confirmatory analysis results are of three general types: (1) 
    Results from analyzers that automatically collect and analyze samples 
    from the blend on a continuous or very frequent basis, called ``on-
    line'' analysis results; (2) results from samples that are collected 
    from the batch on a less frequent basis and analyzed at a separate 
    laboratory, sometimes called ``grab samples'' or ``off-line'' analysis 
    results; and (3) results from samples of the blendstocks used to 
    produce the batch, together with the proportions of the blendstocks 
    used.
        The attest procedures proposed for in-line blending waiver 
    situations are divided into two broad parts. First, the auditor would 
    review the EPA-approved in-line blending waiver, to identify the 
    requirements regarding the collection, analysis and recording of the 
    primary analysis result, and all confirmatory analysis results. In the 
    second part of the procedures, the auditor would compare the primary 
    analysis result with the confirmatory analysis results for each 
    regulated parameter. Detailed attest procedures are proposed for these 
    primary/confirmatory comparisons.
        In the case of parameters that are confirmed using on-line analysis 
    results, the auditor would identify the on-line analysis results that 
    correspond to twelve discrete times during the blend. These twelve 
    confirmatory results then would be compared with the primary result.
        In the case of parameters confirmed using off-line analysis 
    results, the auditor would compare the primary result with a randomly 
    selected portion of the confirmatory results.
        For parameters confirmed using blendstock analysis results, the 
    auditor would, for twelve discrete times during the blend, identify the 
    proportions of the different blendstocks being used, and the analysis 
    results for these blendstocks. The confirmatory analysis result for the 
    parameter at issue for each discrete time then would be calculated as 
    the volume-weighted total of the blendstock analysis results for that 
    parameter.
        Under the proposed attest procedures, each confirmatory analysis 
    result would be evaluated in several ways. First, the auditor would 
    determine if the confirmatory sample was collected, analyzed and 
    recorded in accordance with the petition as approved by EPA. Second, 
    the confirmatory analysis result would be compared with the primary 
    analysis result. EPA understands that there normally will be some 
    difference between the primary and confirmatory analysis results. 
    Nevertheless, the magnitude and direction of the differences would give 
    the auditor, the refiner, and EPA important information relevant to 
    whether the primary analysis result is accurate.
        The third evaluation of the confirmatory analysis result would 
    address compliance with per-gallon standards. The per-gallon standards 
    are oxygen and benzene under the complex model--the per-gallon minimum 
    or maximum where the standard is being met on average, or the per-
    gallon standard where the standard is being met per gallon. In 
    addition, and as discussed above in preamble section III.A.1, the 
    complex model valid range limits are per-gallon standards for all 
    parameters. Under Sec. 80.41, each of these standards must be met on a 
    per-gallon basis, and no portion of in-line blended gasoline may 
    violate these standards even if a blend meets the standards overall. 
    The auditor would report as a finding any analysis result that violates 
    an applicable per-gallon standard.
        EPA is proposing that the in-line blending waiver attest engagement 
    initially would review a random sample of the in-line blended batches. 
    This would be a departure from the current requirement that each batch 
    of in-line blended gasoline must be audited. Under the proposal, if any 
    primary/confirmatory comparison differed by an amount greater than the 
    ranges specified in Sec. 80.65(e) for independent sampling and testing 
    analysis comparisons, or if any sample violated a per-gallon standard, 
    this random sample would be expanded.
        Under Sec. 80.65(f)(4)(ii)(C), reports for attest engagements must 
    be submitted by February 28 each year for the prior calendar year. This 
    attest reporting deadline is significantly earlier than the May 31 
    deadline for other attest reports. EPA now believes that the overall 
    attest engagement activity, and the reports for those attest 
    engagements, would benefit if the dates were harmonized. As a result, 
    EPA is proposing that the in-line blending waiver attest reports would 
    be submitted by May 31 each year for the prior calendar year's 
    activity. As a result of this proposed timing change, EPA believes that 
    refiners would be able to commission a single attest engagement that 
    would address all refinery activities, including the proposed in-line 
    blending waiver attest procedures, and to submit reports for all attest 
    engagement work at the same time.
        EPA requests comment on this proposal to harmonize the reporting 
    date for attest engagements, and the requirement that a single report 
    be submitted that reflects all attest engagement work for a calendar 
    year reporting period.
        EPA also requests comment on the proposed in-line blending waiver 
    attest procedures in general. In particular, EPA requests comment on 
    whether each batch of in-line blended gasoline should be audited in 
    every case, as opposed to the statistical sampling approach being 
    proposed. In addition, EPA requests comment on an option of auditing a 
    portion of the batches of each grade of in-line blended gasoline. The 
    rationale for requiring grade-specific sampling is that for any 
    particular refinery the diversity in gasoline quality between grades is 
    likely to be greater than the diversity in quality between batches of 
    the same grade.
    
    VIII. Environmental and Economic Impacts
    
        The environmental impacts of today's proposal would be minimal, if 
    any. Most of the revisions proposed today are the result of a 
    determination that certain regulatory requirements may be relaxed 
    without detriment to the environment. Economic impacts would be 
    generally beneficial to affected parties due to the additional 
    flexibility proposed in today's notice. Anti-competitive effects would 
    not be expected. The environmental and economic impacts of the 
    reformulated gasoline program are described in the Regulatory Impact 
    Analysis supporting the December 1993 rule, which is available in 
    Public Docket A-92-12 located at Room M-1500, Waterside Mall (ground 
    floor), U.S. Environmental Protection Agency, 401 M Street, SW., 
    Washington, DC 20460.
    
    IX. Public Participation
    
        EPA desires full public participation in arriving at its final 
    decisions and solicits comments on all aspects of this proposal. 
    Wherever applicable, full
    
    [[Page 37373]]
    
    supporting data and detailed analysis should also be submitted to allow 
    EPA to make maximum use of the comments. All comments should be 
    directed to the EPA Air Docket, Docket A-97-03 (See ADDRESSES). See the 
    DATES section for the deadline for submission of comments.
        Today's rule proposes a variety of modifications to the standards 
    and requirements for reformulated and conventional gasoline. While many 
    of the proposed modifications would reduce compliance burdens on 
    industry, a few modifications may have the effect of restricting 
    compliance flexibility. EPA specifically solicits comments on the need 
    to take the actions that would reduce this flexibility, including 
    comments on whether there are less restrictive measures that EPA may 
    take.
        Any proprietary information being submitted for the Agency's 
    consideration should be markedly distinguished from other submittal 
    information and clearly labeled ``Confidential Business Information.'' 
    Proprietary information should be sent directly to the contact person 
    listed above, and not to the public docket, to ensure that it is not 
    inadvertently placed in the docket. Information thus labeled and 
    directed shall be covered by a claim of confidentiality and will be 
    disclosed by EPA only to the extent allowed, and by the procedures set 
    forth in 40 CFR part 2. If no claim of confidentiality accompanies a 
    submission when it is received by EPA, it may be made available to the 
    public without further notice to the commenter.
    
    X. Regulatory Flexibility
    
        The Regulatory Flexibility Act (RFA) generally requires an agency 
    to conduct a regulatory flexibility analysis of any rule subject to 
    notice and comment rulemaking requirements unless the agency certifies 
    that the rule will not have a significant economic impact on a 
    substantial number of small entities. Small entities include small 
    businesses, small not-for-profit enterprises, and small governmental 
    jurisdictions.
        I certify that this action will not have a significant economic 
    impact on a substantial number of small entities. The proposed 
    revisions contained in today's action would affect small business 
    refiners, importers, oxygenate blenders, distributors, wholesale 
    purchaser-consumers, and retailers of gasoline. In addition, this 
    action would affect small business laboratories that serve as 
    independent laboratories for purposes of fulfilling the independent 
    sampling and testing requirement for reformulated gasoline. However, 
    for the following reasons, EPA has determined that this action would 
    not have an adverse economic impact on these entities.
        In the case of small business oxygenate blenders, distributors, 
    wholesale purchaser-consumers and retailers of gasoline, the proposed 
    revisions would provide greater flexibility and clarity with regard to 
    existing requirements and would not have an adverse impact on these 
    entities. However, the revision which would disallow the use of 
    composite sampling of conventional gasoline would impose an additional 
    burden on small refiners and importers that do not have the laboratory 
    capability to test for all parameters and must send samples to other 
    laboratories for testing. Composite sampling allows refiners and 
    importers to demonstrate compliance based on the testing of fewer 
    gasoline samples. EPA believes, however, that the increased flexibility 
    created by the relaxation and deletion of other refiner and importer 
    requirements under today's action would more than offset any burden 
    created by disallowing composite sampling. Today's action, for example, 
    proposes provisions which would: Allow importers to treat finished 
    gasoline as blendstock to provide flexibility to correct off-spec 
    imported gasoline; allow refiners to use conventional gasoline to 
    produce RFG, which is currently prohibited; modify the sampling and 
    testing requirements for refiners who produce gasoline by blending 
    butane; eliminate the requirement for refiners of conventional gasoline 
    who also import gasoline to calculate a special baseline for their 
    imported gasoline; modify the requirements for every-batch testing of 
    gasoline imported by truck; make the requirements for the accounting of 
    blendstocks for conventional gasoline less restrictive; make the attest 
    engagement procedures more efficient; and modify the reporting 
    requirements for conventional gasoline to delete the requirements to 
    report the grade of gasoline and include ethanol properties in the 
    batch report. Other provisions would aid refiners and importers by 
    clarifying and providing additional guidance with regard to existing 
    requirements. EPA is also proposing provisions which would minimize the 
    effect of disallowing composite sampling by allowing an alternative 
    test method for sulfur content. EPA believes that most refiners have 
    the equipment required to perform the regulatory tests at their 
    refinery except for sulfur under the current regulatory test method. 
    Today's action would allow the use of a cost effective alternative test 
    method for sulfur until September 1, 1998, the date on which EPA 
    anticipates completion of a performance based test method rulemaking.
        With regard to small business laboratories, there would be no 
    increase in economic burden as a result of today's action. This action 
    proposes to impose regulatory liability on entities serving as 
    independent laboratories for failure to perform the duties necessary to 
    fulfill the independent sampling and testing requirement (i.e., 
    following prescribed procedures, retaining records, reporting to EPA). 
    However, there would be no additional costs to either the laboratories 
    or the refiners or importers who contract for the laboratory services, 
    since the refiners and importers would continue to contract and pay for 
    these services as they do under the current regulations. In addition, 
    this action is not expected to affect a substantial number of small 
    business laboratories, as the total number of laboratories currently 
    registered with EPA is well under 100.
        The EPA prepared a Regulatory Flexibility Analysis (RFA) for the 
    final rule establishing standards for reformulated and conventional 
    gasoline (59 FR 7716 (February 16, 1994)), which includes an analysis 
    of the impact of these regulations on small refiners. The RFA is in the 
    docket for that rulemaking: EPA Air Docket A-92-2.
    
    XI. Executive Order 12866
    
        Under Executive Order 12866 (58 FR 51735 (October 4, 1993)), the 
    Agency must determine whether the regulatory action is ``significant'' 
    and therefore subject to OMB review and the requirements of the 
    Executive Order. The Order defines ``significant regulatory action'' as 
    one that is likely to result in a rule that may:
        (1) Have an annual effect on the economy of $100 million or more or 
    adversely affect in a material way the economy, a sector of the 
    economy, productivity, competition, jobs, the environment, public 
    health or safety, or State, local or tribal governments or communities;
        (2) Create a serious inconsistency or otherwise interfere with an 
    action taken or planned by another agency;
        (3) Materially alter the budgetary impact of entitlements, grants, 
    user fees, or loan programs or the rights and obligations of recipients 
    thereof; or
        (4) Raise novel legal or policy issues arising out of legal 
    mandates, the President's priorities, or the principles set forth in 
    the Executive Order.
        It has been determined that this rule is not a significant action 
    under the
    
    [[Page 37374]]
    
    terms of the Executive Order 12866, and is therefore not subject to OMB 
    review.
    
    XII. Paperwork Reduction Act
    
        The information collection requirements in this proposed rule have 
    been submitted for approval to the Office of Management and Budget 
    (OMB) under the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. An 
    Information Collection Request (ICR) document has been prepared by EPA 
    (ICR No. 1591.09) and a copy may be obtained from Sandy Farmer, OPPE 
    Regulatory Information Division; U.S. Environmental Protection Agency 
    (2137); 401 M St., SW., Washington, DC 20460 or by calling (202) 260-
    2740.
        Although many of the revisions proposed in today's rule will have 
    the effect of reducing the information collection requirements of the 
    RFG/anti-dumping regulations, the proposed deletion of the composite 
    sampling provision will mean that refiners and importers of 
    conventional gasoline will be required to test each batch of gasoline 
    rather than test a composite sample comprised of samples of two or more 
    batches of gasoline. As discussed in Preamble Section VI.B.6., EPA is 
    proposing this revision because EPA believes that composite sampling 
    may not provide the accurate results necessary for measuring compliance 
    by refiners and importers under the anti-dumping program, and may pose 
    a significant risk with regard to the enforcement and assurance of 
    compliance.
        The EPA estimates that refiners and importers currently spend 
    approximately 1.67 hours of information collection per batch for 
    compliance testing of conventional gasoline pursuant to the 
    reformulated gasoline and anti-dumping final rule. This is the 
    estimated burden above the hours refiners had expended on testing prior 
    to promulgation of the rule. Most refiners had been testing every batch 
    of conventional gasoline for some of the same properties for which 
    testing is required under the rule.
        Under the current rule, samples of conventional gasoline may be 
    composited over a period up to one month. At a rate of one test per 
    month, the number of hours spent per refiner/importer per year would be 
    20.04 hours. EPA estimates that there are approximately 230 refiners 
    and importers subject to this rule. If all of these refiners and 
    importers were to base their compliance on one composite sample per 
    month, the total burden on industry would be 4,609.20 hours per year. 
    EPA believes, however, that many refiners and importers currently 
    conduct tests on every batch of gasoline rather than on composite 
    samples, or test composite samples comprised of fewer batches than are 
    produced over a one-month period. EPA believes, therefore, that, in 
    practice, the number of hours currently spent on testing by industry is 
    likely to be much greater than this figure.
        EPA estimates that, without the composite sampling option, refiners 
    and importers would test an average of approximately 158 batches of 
    conventional gasoline per refiner/importer per year. Applying the 
    estimate of 1.67 hours per batch, the total number of hours per 
    refiner/importer per year would be 263.86 hours, or a total of 
    60,687.80 hours industry-wide. If all 230 refiners and importers 
    currently were basing compliance on one composite sample per month, the 
    incremental burden of this action on industry would be 56,078.60 hours. 
    At an estimated cost of $53.31 per test for information collection, the 
    total incremental cost of the additional testing burden to industry 
    would be approximately $1,790,150. However, as discussed above, most 
    refiners conducted every-batch testing of some properties prior to 
    promulgation of the final rule, and many refiners currently test every 
    batch for compliance purposes rather than base compliance on the 
    testing of composite samples. Therefore, EPA believes that the 
    incremental burden of this proposed action on industry would be much 
    smaller.
        This action also proposes to eliminate the per-gallon 
    NOX minimum standards for complex model averaged RFG, and 
    increase the number of compliance surveys required beginning in 1998 
    and thereafter from 50 to 70. EPA is proposing to eliminate the 
    NOX per-gallon minimum standards because these standards may 
    impose substantial costs in producing RFG without commensurate benefits 
    to the environment. (See Preamble Section III.A.1.). The NOX 
    per-gallon minimum standards were included in the final rule as a tool 
    to assure an even distribution of NOX benefits from area to 
    area. However, EPA believes that a less costly alternative, an increase 
    in the number of required surveys, would achieve a similar level of 
    assurance of even distribution of NOX benefits. EPA 
    estimates that the incremental cost burden of these additional surveys 
    will be roughly $1,100,000 industry-wide (20 additional surveys at 
    approximately $55,000 each), or about $7,333 per RFG refiner or 
    importer ($1,100,000 150 refiners/importers). The increased cost burden 
    due to the additional survey requirement, however, would be more than 
    offset by the elimination of the burden on industry imposed by the per-
    gallon NOX minimum standards.
        Burden means the total time, effort, or financial resources 
    expended by persons to generate, maintain, retain, or disclose or 
    provide information to or for a Federal agency. This includes the time 
    needed to review instructions; develop, acquire, install, and utilize 
    technology and systems for the purposes of collecting, validating, and 
    verifying information, processing and maintaining information, and 
    disclosing and providing information; adjust the existing ways to 
    comply with any previously applicable instructions and requirements; 
    train personnel to be able to respond to a collection of information; 
    search data sources; complete and review the collection of information; 
    and transmit or otherwise disclose the information.
        An Agency may not conduct or sponsor, and a person is not required 
    to respond to a collection of information unless it displays a 
    currently valid OMB control number. The OMB control numbers for EPA's 
    regulations are listed in 40 CFR part 9 and 48 CFR Chapter 15.
        Comments are requested on the Agency's need for this information, 
    the accuracy of the provided burden estimates, and any suggested 
    methods for minimizing respondent burden, including through the use of 
    automated collection techniques. Send comments on the ICR to the 
    Director, OPPE Regulatory Information Division; U.S. Environmental 
    Protection Agency (2137), 401 M St., SW., Washington, DC 20460; and to 
    the Office of Information and Regulatory Affairs, Office of Management 
    and Budget, 725 17th St., NW., Washington, DC 20503, marked 
    ``Attention: Desk Officer for EPA.'' Include the ICR number in any 
    correspondence. Since OMB is required to make a decision concerning the 
    ICR between 30 and 60 days after July 11, 1997, a comment to OMB is 
    best assured of having its full effect if OMB receives it by August 11, 
    1997. The final rule will respond to any OMB or public comments on the 
    information collection requirements contained in this proposal.
    
    XIII. Unfunded Mandates Act
    
        Under section 202 of the Unfunded Mandates Reform Act of 1995 
    (``Unfunded Mandates Act''), signed into law on March 22, 1995, EPA 
    must prepare a budgetary impact statement to accompany any proposed or 
    final rule that includes a Federal mandate that may result in 
    expenditure by State, local, and tribal governments, in the
    
    [[Page 37375]]
    
    aggregate; or by the private section, of $100 million or more. Under 
    section 205, EPA must select the most cost-effective and least 
    burdensome alternative that achieves the objectives of the rule and is 
    consistent with the statutory requirements. Section 203 requires EPA to 
    establish a plan for informing and advising any small governments that 
    may be significantly or uniquely impacted by the rule.
        EPA has determined that the action proposed today does not include 
    a Federal mandate that may result in estimated costs of $100 million or 
    more to either State, local or tribal governments in the aggregate, or 
    to the private sector. This action has the net effect of reducing 
    burdens of the reformulated gasoline program on regulated entities. 
    Therefore, the requirements of the Unfunded Mandates Act do not apply 
    to this action.
    
    XIV. Statutory Authority
    
        The statutory authority for the actions proposed today is granted 
    to EPA by sections 114, 211 (c) and (k), and 301 of the Clean Air Act, 
    as amended; 42 U.S.C. 7414, 7545 (c) and (k), and 7601.

        (a) Sample collection, handling, and compositing procedures. Any 
    person who samples reformulated or conventional gasoline, or 
    blendstocks used to produce reformulated or conventional gasoline, in 
    order to meet any requirement of subparts D or E shall follow the 
    procedures specified in Sec. 80.8.
    
    [[Page 37379]]
    
        (b) Determination of homogeneity for reformulated and conventional 
    gasoline. Homogeneity of the gasoline shall be determined prior to 
    preparation of, or analysis of, the sample used to establish the batch 
    properties for purposes of Secs. 80.65(e), 80.72 and 80.101(i). 
    Homogeneity shall be determined as follows.
        (1) Where the gasoline contained in a single tank or compartment is 
    to be treated as a single batch:
        (i) By collecting, at a minimum, upper, middle, and lower spot or 
    tap samples following the procedures referenced in Secs. 80.8 (a) and 
    (c); or
        (ii)(A) By following procedures for tank mixing that result in 
    complete tank homogeneity, that the party is able to demonstrate 
    through historic sampling and testing data for the same types of 
    blendstocks, storage tank configuration, mixing apparatus, and mixing 
    protocol; and
        (B) By collecting, at a minimum, upper, middle, and lower spot or 
    tap samples of the batch, analyzing these samples for gravity, and 
    demonstrating that the gravity values do not differ by more than 
    0.3 deg. API, unless it is not possible to collect spot or tap samples 
    from the storage tank.
        (2) Where the product contained in a marine vessel with multiple 
    compartments is to be treated as a single batch, by collecting a sample 
    from each compartment using the running sample collection procedure 
    referenced in Secs. 80.8 (a) and (c).
        (3) The samples collected under paragraphs (b)(1)(i) and (b)(2) of 
    this section shall be analyzed for each parameter for which the batch 
    is subject to, or that is used to calculate an emissions performance 
    for which the batch is subject to, a standard specified in Sec. 80.41 
    or Sec. 80.101.
        (4) The analyses under paragraph (b)(3) of this section shall use 
    the test methods specified in Sec. 80.46, or alternative test methods 
    for which the party is able to demonstrate correlation to the values 
    obtained by the methods specified in Sec. 80.46.
        (5)(i) For gasoline to be considered homogeneous, the maximum 
    difference in the analytical results of samples collected under 
    paragraphs (b)(1)(i) and (b)(2) of this section shall be no larger than 
    the range specified in Sec. 80.65(e)(2)(i) for each parameter; however
        (ii) In no case may any sample violate a per-gallon minimum or 
    maximum standard under Sec. 80.41 that is applicable to the batch.
        (6) If the gasoline meets the criteria to be considered 
    homogeneous, it may be treated as a batch pursuant to Sec. 80.2(gg).
        (c) Additional sampling options for imported gasoline. (1) In the 
    case of imported reformulated gasoline, the gasoline contained in 
    marine vessels with multiple compartments may be treated as a single 
    batch of reformulated gasoline and the properties may be based on a 
    volume weighted composite sample prepared using the procedures 
    referenced in Sec. 80.8(d) provided that:
        (i) All of the gasoline contained in the multiple compartments is 
    transferred to a single shore tank; or
        (ii) The gasoline from the vessel is transferred to multiple shore 
    tanks and is determined for each tank separately to meet all per-gallon 
    minimum or maximum standards under Sec. 80.41 that are applicable to 
    the batch, using the following procedure:
        (A) The gasoline contained in the storage tanks prior to the 
    transfer of any gasoline from the vessel (the ``heels'') shall be 
    sampled and tested using the test methods specified in Sec. 80.46, or 
    alternative test methods for which the party is able to demonstrate 
    correlation to the values obtained by the methods specified in 
    Sec. 80.46;
        (B) The gasoline contained in the storage tanks subsequent to the 
    transfer of all gasoline from the vessel shall be sampled and tested 
    using the test methods specified in Sec. 80.46, or alternative test 
    methods for which the party is able to demonstrate correlation to the 
    values obtained by the methods specified in Sec. 80.46; and
        (C) The volume and properties of the heels shall be subtracted from 
    the volume and properties of the filled tanks to determine the volume 
    and properties of the gasoline from the vessel only.
        (iii) RVP is determined using the volume weighted average of the 
    individual compartment sample results, analyzed prior to preparation of 
    the batch composite sample.
        (2) In the case of imported reformulated gasoline, the gasoline 
    transferred to shore tanks from marine tank vessels may be certified 
    based on shore tank sampling following the procedures of paragraphs 
    (c)(1)(ii) (A) through (C) of this section, except that testing must be 
    performed using only the methods specified in Sec. 80.46.
        (3) In the case of imported conventional gasoline the gasoline 
    contained in marine vessels with multiple compartments may be treated 
    as a single batch, provided that gasolines of different octane grades 
    (e.g., premium, mid-grade and regular) are treated as separate batches.
        (d) Requirements for RBOB. Each requirement of this section that 
    applies to reformulated gasoline also applies to RBOB.
        13. Section 80.49 is amended by revising the paragraph (a) 
    introductory text, the entry for ``New Parameter'' in the table in 
    paragraph (a)(1), paragraph (a)(3), introductory text, and the first

        20. Section 80.72 is added to subpart D to read as follows:
    
    
    Sec. 80.72  Independent analysis requirements.
    
        (a) Independent sampling and analysis required. Any refiner or 
    importer of reformulated gasoline or RBOB shall carry out a program of 
    independent sample collection and analyses for the reformulated 
    gasoline it produces or imports, which meets the requirements of one of 
    the following two options:
        (1) Option 1. The refiner or importer shall, for each batch of 
    reformulated gasoline or RBOB that is produced or imported, have the 
    gasoline sampled and tested by the designated independent laboratory 
    according to the requirements specified in this section.
        (2) Option 2. The refiner or importer shall have a periodic 
    independent testing program carried out for all reformulated gasoline 
    or RBOB produced or imported, which shall consist of the designated 
    independent laboratory sampling each batch of reformulated gasoline or 
    RBOB, and analyzing each sample identified under paragraph (d) of this 
    section, according to the requirements specified in this section.
        (b) Designation of independent laboratory. (1) Any refiner or 
    importer shall designate one independent laboratory for each refinery 
    or import facility at which reformulated gasoline or RBOB is produced 
    or imported, and shall identify this laboratory to EPA under the 
    registration requirements of Sec. 80.76.
        (2) In order to be considered independent:
        (i) The laboratory shall not be operated by any refiner or importer 
    who produces or imports reformulated gasoline or RBOB, or by any 
    refiner or importer that is part of a corporate organization that 
    includes a refiner or importer of reformulated gasoline or RBOB, 
    including subsidiary corporations, parent corporations and subsidiaries 
    thereof, and employees of any of these corporations;
        (ii) The laboratory shall be free from any interest in any refiner 
    or importer; and
        (iii) The refiner or importer shall be free from any interest in 
    the laboratory; however
        (iv) Notwithstanding the restrictions in paragraphs (b)(2)(i) 
    through (iii) of this section, a laboratory shall be considered 
    independent if it is owned or operated by a gasoline pipeline company, 
    regardless of ownership or operation of the gasoline pipeline company 
    by refiners or importers, provided that such pipeline company is owned 
    and operated by four or more refiners or importers.
        (3) Use of a laboratory that is debarred, suspended, or proposed 
    for debarment pursuant to the Governmentwide Debarment and Suspension 
    regulations, 40 CFR part 32, or the Debarment, Suspension and 
    Ineligibility provisions of the Federal Acquisition Regulations, FAR 48 
    subpart 9.4, shall be deemed noncompliance with the requirements of 
    this section.
        (4) Any laboratory that fails to comply with the requirements of 
    this section shall be subject to debarment or suspension under 
    Governmentwide Debarment and Suspension regulations, 40 CFR part 32, or 
    the Debarment, Suspension and Ineligibility regulations, Federal 
    Acquisition Regulations FAR 48 subpart 9.4.
        (c) Sampling and reporting. For all samples collected or analyzed 
    pursuant to the requirements of this section, the
    
    [[Page 37386]]
    
    refiner or importer shall have the independent laboratory:
        (1) Collect a representative sample from the batch of reformulated 
    gasoline following the sampling procedures specified in Sec. 80.47;
        (2) Determine which standards are being met on a per-gallon basis 
    and which standards are being met on average, and obtain the refiner's 
    or importer's assigned batch number for the batch being sampled;
        (3) Determine the volume of the batch;
        (4) Determine the identification number of the gasoline storage 
    tank or tanks in which the batch was stored at the time the sample was 
    collected;
        (5) Determine the date and time the batch became finished 
    reformulated gasoline, and the date and time the sample was collected;
        (6) Determine the grade of the batch (e.g., premium, mid-grade, or 
    regular); and
        (7) In the case of reformulated gasoline produced through computer-
    controlled in-line blending, determine the date and time the blending 
    process began and the date and time the blending process ended, unless 
    exempt under Sec. 80.65(f)(2);
        (8) Retain each sample for a period of 30 days, except that this 
    period shall be extended to a period of up to 180 days upon request by 
    EPA; and
        (9) Supply to EPA any sample collected or a portion of any such 
    sample, according to the requirements of paragraph (f) of this section.
        (d) Selecting samples for analysis. A refiner or importer shall 
    have any laboratory serving as the independent laboratory under the 
    periodic independent analysis option of paragraph (a)(2) of this 
    section, for each refinery or importer, analyze gasoline samples 
    identified as follows:
        (1) General instructions. (i) Samples must be selected for analysis 
    for each two week period. Each two-week period begins on Sunday night 
    at midnight, and lasts for the subsequent two weeks. The first two-week 
    period begins at midnight on August 7, 1994, the second two-week period 
    begins at midnight on August 21, 1994, etc.
        (ii) EPA may issue special instructions for selecting samples for 
    analysis for any specific refiner, refinery, importer, or independent 
    lab that differ in whole or in part from the instructions contained in 
    this paragraph (d), and if such special instructions are issued they 
    must be followed instead of the instructions contained in this 
    protocol.
        (2) Identify samples for the current analysis cycle. (i) Identify 
    each sample of RFG or RBOB collected during the preceding two-week 
    period, and the refiner or importer assigned batch identification 
    number for each sample.
        (ii) Add any samples carried over from a prior analysis cycle, from 
    paragraphs (d)(3)(i) and (ii) of this section.
        (iii) Order the samples from the preceding two-week period, plus 
    any carry over samples, in chronological order using the batch 
    identification number for each sample.
        (3) Determine the number of samples to be analyzed.
        (i) The number of samples that must be analyzed for the current 
    analysis cycle is the number of samples identified under paragraph 
    (d)(2) of this section that is evenly divisible by ten.
        (ii) Any remainder from this division is the number of samples that 
    must be carried over to the subsequent analysis cycle. Any carry over 
    samples must be those with the largest batch identification numbers.
    
        Example. If the number of samples identified under paragraph 
    (d)(2) is thirty seven, with batch numbers 4321-54321-95-002534 
    through 4321-54321-95-002570, the number of samples that must be 
    analyzed in the current analysis cycle is three, and seven samples 
    must be carried over to the subsequent analysis cycle. The specific 
    samples that must be carried over are those seven with the largest 
    batch identification numbers, or samples 4321-54321-95-002564 
    through 4321-54321-95-002570.
    
        (iii) To the extent any sample carry over would result in a sample 
    being retained by the independent lab for more than 30 days, this 
    sample shall be retained by the independent laboratory until the sample 
    is not carried over to a subsequent analysis cycle, but for a maximum 
    of 180 days.
        (iv)(A) If the number of samples identified under paragraph (d)(2) 
    of this section is less than ten, then all samples should be carried 
    over to the subsequent analysis cycle.
        (B) If the number of samples identified under paragraph (d)(2) of 
    this section is less than ten, and any sample carry over would result 
    in a sample being retained for more than 180 days, then one sample must 
    be analyzed from the number, and none of the samples would be carried 
    over to the subsequent analysis cycle.
        (4) Identify which samples to analyze. (i) Identify the beginning 
    point for using the Random Number Table at paragraph (d)(4)(ii) of this 
    section for the current analysis cycle.
        (A) Identify the last two digits from the closing point for the Dow 
    Jones Industrial Average as reported in the Wall Street Journal for the 
    first day the New York Stock Exchange is open following the close of 
    the preceding two-week period.
    
        Example. For the two-week period ending at midnight on Sunday, 
    August 20, the relevant two digits would be the last two digits for 
    the close for the Dow Jones Industrial Average for Monday, August 
    21, as reported in the Wall Street Journal for Tuesday, August 22. 
    If this Dow Jones Industrial Average close is 3,741.06, the relevant 
    two digits would be 06.
    
        (B) The beginning point for the Random Number Table at paragraph 
    (d)(4)(ii) of this section for the current analysis cycle is the row 
    number (from Column A of the Random Number Table) that corresponds to 
    the number identified under paragraph (d)(4)(i)(A) of this section. 
    Using the example from paragraph (d)(4)(i)(A) of this section, the 
    applicable row number would be 06, and the first random number would be 
    27.

        (iii) For each sample for the current analysis cycle under 
    paragraph (d)(2) of this section, excluding any samples carried over to 
    the subsequent analysis cycle under paragraphs (d)(3)(ii) or 
    (d)(3)(iv)(A) of this section, identify the last two digits of the 
    batch identification number. This process is illustrated in the 
    following table:
    
    ------------------------------------------------------------------------
                                                                   The last 
                      If the batch number is:                     two digits
                                                                     are:   
    ------------------------------------------------------------------------
    4321-54321-95-002533.......................................           33
    4321-54321-95-002593.......................................           93
    ------------------------------------------------------------------------
    
        (iv) Compare the two digit number from Column B of the Random 
    Number Table at the beginning point identified under paragraph 
    (d)(4)(ii) of this section (the first random number) with each of the 
    two digit sample numbers identified under paragraph (d)(4)(iii) of this 
    section.
        (v) If the first random number matches any sample number, this 
    sample is identified as a sample for analysis. If the random number 
    matches more than one sample number, only the sample with the lowest 
    batch identification number is identified as a sample for analysis.
        (vi) If the first random number does not match any sample number, 
    then move to the next number in the Random Number Table, and repeat the 
    process described under paragraph (d)(4)(v) of this section. In the 
    example under paragraph (d)(4)(iii) of this section, there is no match 
    for the first random number (27), but there is a match for the second 
    random number (93), and sample number 4321-54321-95-002593 would be 
    identified for analysis.
        (vii) Continue this process until the number of samples identified 
    for analysis equals the number under paragraphs (d)(3)(i) or (d)(4)(ii) 
    of this section.
        (e) Analysis of samples. (1) Any independent laboratory who 
    analyzes a sample under the requirements of this section shall use the 
    analysis methodologies specified in Sec. 80.46.
        (2) If a sample to be analyzed is of RBOB, the sample first must be 
    blended with oxygenate as follows:
        (i) If the RBOB is designated as any-oxygenate, ethanol shall be 
    blended at a volume that results in 2.0 wt% oxygen;
        (ii) If the RBOB is designated as ether-only, MTBE shall be blended 
    at a volume that results in 2.0 wt% oxygen;
        (iii) If the RBOB is other than any-oxygenate or ether-only, the 
    RBOB shall be blended with the oxygenate specified for the RBOB, or if 
    more than one oxygenate is allowed, from the following list of 
    oxygenates the first that is allowed by the refiner's instructions: 
    Ethanol, MTBE, ETBE, any other specified oxygenate. The volume of 
    oxygenate shall be the volume specified in the refiner's instructions, 
    or if a range is specified, the minimum volume specified.
        (f) Shipment of samples to EPA.--(1) Quality assurance samples. Any 
    laboratory serving as the independent laboratory under this section 
    shall, for each refinery or importer, supply certain gasoline samples 
    to EPA according to the following requirements. Notwithstanding the 
    gasoline samples identified in this paragraph (f), EPA may specify a 
    different frequency for sending samples to EPA for any refiner, 
    refinery, importer, or independent lab, and if such different frequency 
    is specified it must be followed.
        (2) Refiners and importers using the periodic independent analysis 
    option. (i) In the case of samples identified for analysis under 
    paragraph (d) of this section, for each thirty-third sample that is 
    analyzed for each refinery or importer a portion of the sample must be 
    sent to EPA.
        (ii) In the case of samples that are not identified for analysis 
    under paragraph (d) of this section, each thirty-third sample that is 
    collected for each refinery or importer but that is not analyzed by the 
    independent laboratory must be sent to EPA.
        (3) Refiners and importers using the 100% independent analysis 
    option. In the case of refiners and importers using the 100% 
    independent analysis option of paragraph (a)(1) of this section, for 
    every thirty-third sample that is analyzed for each refinery or 
    importer, a portion of the sample must be sent to EPA.
        (4) Samples that violate applicable standards. (i) The remaining 
    portion of each sample that violates an applicable per-gallon standard 
    must be labeled as such and shipped to EPA.
        (ii) The applicable standards are those specified under Sec. 80.41. 
    In the case of standards being met on a per-gallon basis, the per-
    gallon standards are the applicable standards. In the case of standards 
    being met on an average basis,
    
    [[Page 37388]]
    
    the per-gallon minimums and maximums are the applicable standards. 
    Beginning on January 1, 1998, per-gallon standards include the complex 
    model range limits specified under Sec. 80.41(h)(3).
        (5) Sample shipping procedures. (i) Each sample sent to EPA must be 
    sealed in containers and transported in accordance with the procedures 
    specified in Sec. 80.8, and identified with the independent lab's name 
    and registration number and the sample information specified in 
    paragraphs (e)(1) through (7) of this section.
        (ii) The quantity of sample that must be sent is: in the case of 
    samples that have been analyzed by the independent lab, the entire 
    volume remaining following the laboratory analysis which should be a 
    minimum of 330mL; and in the case of samples that have not been 
    analyzed by the independent lab, a minimum of 70% of one quart.
        (iii) Samples identified for shipping to EPA must be sent via an 
    overnight package service or a comparable means to the address and 
    following procedures specified by EPA.
        21. Section 80.74 is amended by revising paragraphs (a)(2)(iii), 
    (b)(2), (b)(5) and (b)(6), and adding paragraphs (b)(7), (b)(8), 
    (b)(9), and (h) to read as follows:

    testing apparatus, or where no printed result is generated by the 
    testing apparatus, the results as originally recorded by the person who 
    performed the tests; and
        (B) Any record that contains results for the test that are not 
    identical to the results recorded in paragraph (a)(2)(iii)(A); and
    * * * * *
        (b) * * *
        (2) The information specified in Sec. 80.47(b) used to establish 
    gasoline homogeneity;

    gasoline under paragraphs (a)(1)(iii), (a)(5), (a)(7), (a)(8), and 
    (a)(10) of this section do not apply in the case of a party who is 
    changing the type of gasoline stored in a gasoline storage tank or the 
    type of gasoline transported through a gasoline pipe or manifold within 
    a single facility (a gasoline storage tank, pipe, or manifold change of 
    service ), or in the case of a change of service that involves mixing 
    gasoline with blendstock, provided that:
        (i) The change of service is for a legitimate operational reason 
    and is not for the purpose of combining the categories of gasoline or 
    of combining gasoline with blendstock;
        (ii) Prior to adding product of the new category the volume of 
    product of the old category in the tank, pipe or manifold is made as 
    low as possible through normal pumping operations;
        (iii) The volume of product of the new category that is added to 
    the tank, pipe or manifold is as large as possible taking into account 
    the availability of product of the new category; and
        (iv) In any case where the new category of product is reformulated 
    gasoline, subsequent to adding the gasoline of the new category a 
    representative sample from the tank, pipe or manifold is collected and 
    analyzed, and such analysis shows compliance with each standard under 
    Sec. 80.41 that is relevant to the new gasoline category. The analysis 
    for each standard must be conducted using the method specified under 
    Sec. 80.46, or using another method that is approved by the American 
    Society of Testing and Materials provided that the other method is 
    correlated with the method specified under Sec. 80.46.
        (13) The prohibition against combining reformulated gasoline with 
    RBOB under paragraph (a)(8)of this section does not apply in the case 
    of a party who is changing the type of product stored in a tank from 
    which trucks are loaded, from reformulated gasoline to RBOB, or vice 
    versa, provided that:
        (i) The change of service requirements described in paragraph 
    (a)(12) of this section can not be met without taking the storage tank 
    out of service;
        (ii) Prior to adding product of the new category the volume of 
    product of the old category in the tank is drawn down to the lowest 
    point which allows trucks to be loaded during the transition;
        (iii) The volume of product of the new category that is added to 
    the tank is as large as possible taking into account the availability 
    of product of the new category;
        (iv) When transitioning from RBOB to reformulated gasoline:
        (A) If the reformulated gasoline in the storage tank has a oxygen 
    content of less than 1.5 wt%, oxygenate must be blended into the RFG at 
    the loading rack such that the RFG has a minimum oxygen content of 1.5 
    wt%;
        (B) Subsequent to any oxygenate blending, the reformulated gasoline 
    must meet all applicable standards that apply at the terminal; and
        (C) Prior to the date the VOC-control standards apply to the 
    terminal the reformulated gasoline in the storage tank must have an 
    oxygen content of not less than 1.5 wt%;
        (v) When transitioning from reformulated gasoline to RBOB:
        (A) The oxygen content of the reformulated gasoline produced using 
    the RBOB must be not less than the minimum oxygen amount specified in 
    the RBOB product transfer documents;
        (B) Subsequent to any oxygenate blending, the reformulated gasoline 
    must meet all applicable standards; and
        (C) The transition from reformulated gasoline to RBOB may not begin 
    until the date the VOC-control standards no longer apply to the 
    terminal; and
        (vi) The party must demonstrate compliance with the requirements 
    specified in paragraphs (a)(13)(iv) and (v) of this section through 
    testing of samples collected from the terminal storage tank and from 
    trucks loaded at the terminal subsequent to each receipt of new product 
    until the transition is complete. The analyses must be conducted using 
    the test method specified under Sec. 80.46, or using another test 
    method that is approved by the American Society of Testing and 
    Materials provided that the other method is correlated with the method 
    specified under Sec. 80.46.
        25. Section 80.79 is amended by revising paragraphs (b)(2) and 
    adding paragraphs (b)(3) and (c)(3) to read as follows:
    
    
    Sec. 80.79  Liability for violations of the prohibited activities.
    
    * * * * *
    
    [[Page 37391]]
    
        (b) * * *
        (2) Where a violation is found at a facility which is operating 
    under the corporate, trade or brand name of a refiner or importer, that 
    refiner or importer must show, in addition to the defense elements 
    required by paragraph (b)(1) of this section, that the violation was 
    caused by:
        (i) An act in violation of law (other than the Act or this part), 
    or an act of sabotage or vandalism; or
        (ii) The action of any retailer or wholesale purchaser-consumer 
    supplied by the refiner or importer in violation of a contractual 
    undertaking imposed by the refiner or importer designed to prevent such 
    action, and despite periodic sampling and testing by the refiner or 
    importer to ensure compliance with such contractual obligation; or
        (iii) The action of any reseller, distributor, oxygenate blender, 
    carrier, or a retailer or wholesale purchaser-consumer supplied by any 
    of these persons, in violation of a contractual undertaking imposed by 
    the refiner or importer designed to prevent such action, and despite 
    periodic sampling and testing by the refiner or importer to ensure 
    compliance with such contractual obligation; or
        (iv) The action of any carrier or other distributor not subject to 
    a contract with the refiner or importer but engaged by the refiner or 
    importer for transportation of gasoline, despite specification or 
    inspection of procedures and equipment by the refiner or importer which 
    are reasonably calculated to prevent such action.
        (3) In this paragraph (b), to show that the violation ``was 
    caused'' by any of the specified actions the party must demonstrate by 
    reasonably specific showings, by direct or circumstantial evidence, 
    that the violation was caused or must have been caused by another.
        (c) * * *
        (3) An oversight program conducted by a carrier under paragraph 
    (c)(1) of this section need not include periodic sampling and testing 
    of gasoline in a tank truck operated by a common carrier, but in lieu 
    of such tank truck sampling and testing the common carrier shall 
    demonstrate evidence of an oversight program for monitoring compliance 
    with the requirements of Sec. 80.78 relating to the transport or 
    storage of gasoline by tank truck, such as appropriate guidance to 
    drivers on compliance with applicable requirements and the periodic 
    review of records normally received in the ordinary course of business 
    concerning gasoline quality and delivery.
    * * * * *
        26. Section 80.83 is revised to read as follows:
    
    
    Sec. 80.83  Gasoline treated as blendstock.
    
        An importer may treat imported gasoline as blendstock (Gasoline 
    Treated as Blendstock, or GTAB) and exclude the GTAB from its importer 
    compliance calculations under Sec. 80.65(c) for reformulated gasoline 
    or Sec. 80.101(d) for conventional gasoline provided the importer meets 
    the requirements specified in this section.
        (a) GTAB must be included in the compliance calculations for 
    gasoline produced at a refinery operated by the same person that is the 
    importer (the ``GTAB importer-refiner'').
        (b) The GTAB importer-refiner may not transfer title to GTAB to 
    another person until the GTAB has been used to produce gasoline and all 
    refinery standards and requirements have been met for the gasoline 
    produced.
        (c) The refinery at which GTAB is used to produce gasoline must be 
    physically located at the same terminal at which the GTAB is first 
    discharged upon arrival in the United States (the import facility), or 
    at a facility to which the GTAB is directly transported from the import 
    facility.
        (d) GTAB must be completely segregated from any other gasoline, 
    whether conventional or RFG, and including any gasoline tank bottoms, 
    prior to the point of blending, and sampling and testing, in the 
    refinery operation, except that:
        (1) GTAB may be placed in a storage tank that contains other GTAB 
    imported by that importer; or
        (2) GTAB may be placed in a storage tank that contains gasoline 
    provided that:
        (i) The gasoline has the same designations under Sec. 80.65(d) as 
    the gasoline which will be produced using the GTAB;
        (ii) The blending is performed in that storage tank; and
        (iii) The properties and volume the gasoline produced using GTAB is 
    determined in a manner that excludes the volume and properties of the 
    gasoline.
        (e) Each year that GTAB is used to produce gasoline, the GTAB 
    importer-refiner must determine an adjusted baseline for the refinery 
    where the GTAB is used to produce gasoline that would apply in the case 
    of conventional gasoline standards under Sec. 80.101(b) and 
    reformulated gasoline standards under Sec. 80.41(h)(2)(i) for all 
    gasoline produced at that refinery for that year. The following 
    formulas must be used to calculate the adjusted refinery baseline where 
    GTAB is used to produce conventional gasoline:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.009
    
    [GRAPHIC] [TIFF OMITTED] TP11JY97.010
    
        And the following formula must be used to calculate the adjusted 
    refinery baseline where GTAB is used to produce RFG:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.011
    
    Where:
    
    ABi = Adjusted baseline for parameter or emissions 
    performance i.
    V1990 = 1990 baseline volume for the refinery.
    
    [[Page 37392]]
    
    Va = Volume of RFG, conventional gasoline and RBOB produced 
    at the refinery during the year (averaging period) in question.
    VRFG = Volume of RFG and RBOB produced at the refinery 
    during the year in question.
    VConv = Volume of conventional gasoline produced at the 
    refinery during the year in question.
    VRGTAB = Volume of GATB used to produce conventional 
    gasoline at the refinery during the year in question.
    VCGtab = Volume of GTAB used to produce conventional 
    gasoline at the refinery during the year in question.
    RBi = 1990 refinery baseline for parameter or emissions 
    performance i.
    IBi = Baseline for parameter or emissions performance i that 
    applies to the GTAB importer-refiner in its importer capacity.
    SBi = Statutory baseline for parameter or emissions 
    performance i.
    
        (f)(1) The GTAB importer-refiner must complete all requirements for 
    the GTAB at the time it is imported as if the GTAB were imported 
    gasoline, including sampling and testing, independent sampling and 
    testing for GTAB used to produce reformulated gasoline, record keeping 
    and reporting.
        (2) The volume and properties of GTAB that has been combined with 
    other GTAB may be determined by subtracting the volume and properties 
    of the GTAB in the tank prior to receipt of the new product, from the 
    volume and properties of the GTAB in the tank subsequent to receipt of 
    the new product.
        (3) Any GTAB batch that is used in whole or in part to produce 
    reformulated gasoline must be treated as imported reformulated gasoline 
    for purposes of sampling and testing, and reporting, under paragraph 
    (f)(1) of this section; except that the sampling and testing may be 
    based on vessel composite samples without regard to whether the 
    gasoline in individual ship compartments separately meets the 
    reformulated gasoline downstream standards.
        (4) Any reports to EPA for imported GTAB must identify the GTAB as 
    such.
        (5) Any GTAB that ultimately is not used to produce gasoline must 
    be treated as newly imported gasoline, for which all required sampling 
    and testing, record keeping and reporting must be accomplished, and the 
    gasoline must be included in the GTAB importer-refiner's importer 
    compliance calculations for the averaging period that includes the date 
    this sampling and testing occurs.
        27. Section 80.84 is added to subpart D to read as follows:
    
    
    Sec. 80.84  Treatment of interface and transmix.
    
        (a) Definitions. For purposes of this section, the following 
    definitions apply:

    gasoline blendstock produced from the transmix.
        (2) Any person who separates transmix where the gasoline portion is 
    classified as reformulated gasoline shall meet all requirements and 
    standards that apply to a refinery under 40 CFR subparts D and F with 
    regard to the transmix operation, and shall include the transmix 
    gasoline portion in compliance calculations for the refinery.
        (d) Transmix Blending. (1) Any person may blend transmix into 
    conventional gasoline only if:
        (i) The transmix results from normal pipeline operations;
        (ii) (A) The transmix cannot be transported by pipeline or water to 
    a transmix processing facility; or

    greater of:
        (A) The demonstrated blending rate at that terminal during 1994; or
        (B) 0.25 percent by volume.
        (2) Any person may blend transmix into reformulated gasoline only 
    if:

    under paragraph (d)(1) of this section;
        (iv) The transmix is blended at a rate that does not exceed 0.25 
    percent by volume; and
        (v) After blending the reformulated gasoline is shown through

    standards that apply at the terminal. This sampling and testing shall 
    be at one of the following rates:
        (A) In the case of transmix that is blended in a storage tank, 
    following each occasion transmix is blended; or
        (B) In the case of transmix that is blended in-line, at least twice

        a. Revising paragraph (d)(3) and adding paragraph (d)(5)(iii);
        b. Adding paragraph (e)(1)(iii);
        c. Revising paragraph (f)(2)(ii) introductory text;

        j. Adding paragraph (f)(2)(ii)(I).
        The revisions, additions, and removals are set out to read as 
    follows:
    
    
    Sec. 80.91  Individual baseline determination.
    
    * * * * *
        (d) * * *
        (3) Negligible quantity sampling. Post-1990 testing of a blendstock 
    stream for a fuel parameter listed in this paragraph (d)(3) is not 
    required if the refiner can show, through engineering judgement or past 
    experience, that the fuel parameter exists in the stream at less than 
    or equal to the amount, on average, shown in this paragraph (d)(3) for 
    that fuel parameter. Any fuel parameter shown to exist in a refinery 
    stream in negligible amounts shall be assigned a value of 0.0 or the 
    negligible amount shown below at the refiner's discretion:
    Aromatics, volume percent--1.0
    Benzene, volume percent--0.15
    Olefins, volume percent--1.0
    Oxygen, weight percent--0.2
    Sulfur, ppm--30.0
    * * * * *
        (5) * * *
        (iii) If a refiner measures a blendstock stream for aromatics, 
    benzene, olefins,
    
    [[Page 37393]]
    
    oxygen, or sulfur content and discovers that the measured component 
    level of that stream is below the applicable range for the test method 
    used, the low end of the applicable range may be substituted for the 
    actual measured value in the baseline determination. This paragraph 
    (d)(5)(iii) is not applicable to blendstock streams that have not been 
    explicitly measured.
    * * * * *
        (e) * * *
        (1) * * *
        (iii) For facilities determined to be closely integrated gasoline 
    producing facilities and for which EPA has granted a single set of 
    baseline fuel parameter values per this paragraph (e)(1):
        (A) All reformulated gasoline and anti-dumping standards shall be 
    met by such closely integrated facilities on an aggregate basis;
        (B) A combined facility registration shall be submitted under 
    Secs. 80.76 and 80.103; and
        (C) Record keeping requirements under Secs. 80.74 and 80.104 and 
    reporting requirements under Secs. 80.75 and 80.105 shall be met for 
    such closely integrated facilities on an aggregate basis.
    * * * * *
        (f) * * *
        (2) * * *
        (ii) If the baseline fuel value for aromatics, olefins, benzene, 
    and/or sulfur (determined per paragraph (e) of this section) is higher 
    than the high end of the valid range limits specified in 
    Sec. 80.42(c)(1) if compliance is being determined under the Simple 
    Model, or in Sec. 80.45(f)(1)(ii) if compliance is being determined 
    under the Complex Model, then the valid range limits may be extended 
    for conventional gasoline in the following manner:
    * * * * *
        (D) The new high end of the valid range for sulfur is determined 
    from the following equation:
    
    NSULLIM=SULBASE+50 ppm
    
    Where:
    
    NSULLIM=The new high end of the valid range limit for sulfur, in parts 
    per million
    SULBASE=The seasonal baseline fuel value for sulfur, in parts per 
    million
    
        (E) The extension of the valid range is limited to the applicable 
    summer or winter season in which the baseline fuel values for 
    aromatics, olefins, benzene, and/or sulfur exceed the high end of the 
    valid range as described in paragraph (f)(2)(ii) of this section. Also, 
    the extension of the valid range is limited to use by the refiner whose 
    baseline value for aromatics, olefins, benzene, and/or sulfur was 
    higher than the valid range limits as described in paragraph (f)(2)(ii) 
    of this section.
        (F) Any extension of the Simple Model valid range limits is 
    applicable only to the Simple Model. Likewise any extension of the 
    Complex Model valid range limits is applicable only to the Complex 
    Model.
        (G) The valid range extensions calculated in paragraphs (f)(2)(ii) 
    (A), (B), (C), and (D) of this section are applicable to both the 
    baseline fuel and target fuel for the purposes of determining the 
    compliance status of conventional gasolines. The extended valid range 
    limit represents the maximum value for that parameter above which fuels 
    cannot be evaluated with the applicable compliance model.
        (H) Under the Simple Model, baseline and compliance calculations 
    shall subscribe to the following limitations:
        (1) If the aromatics valid range has been extended per paragraph 
    (f)(2)(ii)(A) of this section, an aromatics value equal to the high end 
    of the valid range specified in Sec. 80.42(c)(1) shall be used for the 
    purposes of calculating the exhaust benzene fraction.
        (2) If the fuel benzene valid range has been extended per paragraph 
    (f)(2)(ii)(C) of this section, a benzene value equal to the high end of 
    the valid range specified in Sec. 80.42(c)(1) shall be used for the 
    purposes of calculating the exhaust benzene fraction.
        (I) Under the Complex Model, baseline and compliance calculations 
    shall subscribe to the following limitations:
        (1) If the aromatics valid range has been extended per paragraph 
    (f)(2)(ii)(A) of this section, an aromatics value equal to the high end 
    of the valid range specified in Sec. 80.45(f)(1)(ii) shall be used for 
    the purposes of calculating emissions performances.
        (2) If the olefins valid range has been extended per paragraph 
    (f)(2)(ii)(B) of this section, an olefins value equal to the high end 
    of the valid range specified in Sec. 80.45(f)(1)(ii) shall be used for 
    the target fuel for the purposes of calculating emissions performances.
        (3) If the benzene valid range has been extended per paragraph 
    (f)(2)(ii)(C) of this section, a benzene value equal to the high end of 
    the valid range specified in Sec. 80.45(f)(1)(ii) shall be used for the 
    target fuel for the purposes of calculating emissions performances.
        (4) If the sulfur valid range has been extended per paragraph 
    (f)(2)(ii)(D) of this section, a sulfur value equal to the high end of 
    the valid range specified in Sec. 80.45(f)(1)(ii) shall be used for the 
    target fuel for the purposes of calculating emissions performances.

        (2) Optional complex model standards. Annual average levels of 
    exhaust benzene emissions, weighted by volume weighted for each batch 
    and calculated using the applicable complex model under Sec. 80.45, 
    shall not exceed the refiner's or importer's compliance baseline for 
    exhaust benzene emissions.
        (3) Complex model standards. (i) Annual average levels of exhaust 
    toxics emissions and NOx emissions, weighted by volume for 
    each batch and calculated using the applicable complex model under 
    Sec. 80.45, shall not exceed the refiner's or importer's compliance 
    baseline for exhaust toxics emissions and NOx emissions, 
    respectively.
        (ii) On a per-gallon basis,
        (A) No conventional gasoline may have properties that are outside 
    the complex model acceptable range limits specified at 
    Sec. 80.45(f)(1)(ii); except that
        (B) For a refinery with a baseline parameter value that is outside 
    the acceptable range limits, the value of this parameter for gasoline 
    produced at this refinery shall not exceed the value determined in 
    Sec. 80.91(f)(2) .

        (iii) Where oxygenate is included in a refinery's or importer's 
    compliance calculations, only the oxygenate volume, excluding 
    denaturant, water and impurities, shall be included in the compliance 
    calculations.
    * * * * *
        (f) Compliance baseline determination. The compliance baseline for 
    any refinery or importer, for each parameter or emissions performance, 
    and for each averaging period, shall be calculated as follows.
        (1) Calculate the refinery's or importer's averaging period volume 
    (Va) as the total volume of the following products produced, 
    imported or blended during the averaging period:
        (i) Conventional gasoline;
        (ii) Oxygenates blended with conventional gasoline downstream if
    
    [[Page 37394]]
    
    allowed under paragraph (d)(4)(ii) of this section;
        (iii) Reformulated gasoline;
        (iv) RBOB;
        (v) Oxygenates added to RBOB as determined under 
    Sec. 80.65(e)(1)(ii); and
        (vi) California gasoline as defined in Sec. 80.81(a)(2).
        (2) Calculate the baseline to averaging period volume ratio (VR) 
    using the following equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.012
    
    where:
    
    VRa=baseline to averaging period volume ratio for averaging 
    period a
    V1990=the refinery's or importer's 1990 baseline volume as 
    determined in Sec. 80.91(f)(1)
    Va=the averaging period volume as calculated in paragraph 
    (f)(1) of this section
    
        (3) If VRa is equal to or greater than 1, the refinery's 
    or importer's compliance baseline shall be the baseline as determined 
    in Sec. 80.91(f)(1).
        (4) If VRa is less than 1, the refinery's or importer's 
    compliance baseline shall be calculated using the following equation:
    
    CBi=(Bi  x  VRa)+(DBi  x  
    (1-VRa))
    
    Where:
    
    CBi=compliance baseline for parameter or emissions 
    performance i
    Bi=the refinery's or importer's baseline for parameter or 
    emissions performance i
    DBi=the statutory baseline for parameter or emissions 
    performance i in Secs. 80.91(c)(5) (iii) and (iv)
    
        (g) Compliance calculations.--(1) Determination of batch parameter 
    and emissions performance values. (i) In the case of each batch subject 
    to the simple model standards, determine the values for sulfur, T-90, 
    olefins, benzene, and aromatics as specified in paragraph (i) of this 
    section.
        (ii) In the case of each batch subject to the early complex or 
    complex model standards:

    standards, calculate the exhaust toxics and NOX emissions 
    using the complex model in Sec. 80.45.
        (2) Compliance determinations--(i) Refineries and importers with an 
    individual baseline. In the case of any refinery or importer subject to 
    an individual baseline, for each parameter or emissions performance 
    subject to a standard under paragraph (b) of this section:
        (A) Except exhaust benzene emissions under the simple model, 
    calculate the annual average parameter value, or annual average 
    emissions performance in mg/mi, using the following formula:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.013
    
    Where:
    
    Pa = annual average value for parameter or emissions 
    performance
    Vi = volume of batch i
    Pi = parameter or emissions performance for batch i
    i = each batch of gasoline or blendstock included in a refinery's or 
    importer's compliance calculations under paragraph (d) of this section
    
        (B) In the case of exhaust benzene emissions under the simple model 
    calculate the annual average value using the following formula:
    
    EXHBEN = 1.884 + (0.949  x  BZ) + (0.113  x  (AR - BZ))
    
    Where:
    
    EXHBEN = annual average simple model exhaust benzene emissions
    BZ = annual average benzene content, calculated under paragraph 
    (g)(2)(i)(A) of this section
    AR = annual average aromatics content, calculated under paragraph 
    (g)(2)(i)(A) of this section
    
        (C) In order to achieve compliance the annual average value shall 
    be equal to or less than the refinery's or importer's standard under 
    paragraph (b) of this section.
        (ii) Refineries and importers with the statutory baseline. In the 
    case of any refinery or importer subject to the statutory baseline, for 
    each parameter or emissions performance subject to a standard under 
    paragraph (b) of this section:
        (A) Calculate the compliance total based on the standard under 
    paragraph (b) of this section for each parameter, or emissions 
    performance in mg/mi, using the formula in Sec. 80.67(g)(1)(i).
        (B) Calculate the actual total for each parameter, or emissions 
    performance in mg/mi, for the gasoline and blendstocks under paragraph 
    (d) of this section, using the formula in Sec. 80.67(g)(1)(ii).
        (C) In order to achieve compliance the actual total shall be equal 
    to or less than the compliance total.
        (3) Additional compliance requirements. (i) Any calculations 
    involving sulfur content or wt% oxygen shall be adjusted for specific 
    gravity.
        (ii) The emissions performance of gasoline that is intended for use 
    in an area subject to an RVP standard in Sec. 80.27 during the period 
    such standard applies and that meets this RVP standard shall be 
    determined using the ``summer'' complex model. The emissions 
    performance of all other gasoline shall be determined using the 
    ``winter'' complex model.
        (4) Oxygen election for NOX. (i) For the 1998 and 1999 
    averaging periods, any refiner for a refinery, or any importer, may 
    elect to determine compliance with the NOX emissions 
    performance standard:
        (A) With oxygenates added downstream from the refinery under 
    Sec. 80.91(e)(4) included in the compliance calculations, and a 
    baseline NOX emissions performance that includes oxygenate; 
    or
        (B) With such oxygenates excluded from compliance calculations, and 
    a baseline NOX emissions performance that excludes 
    oxygenate.
        (ii) The election under paragraph (g)(4)(i) of this section for 
    1999 shall apply for all subsequent averaging periods.
        (5) Exclusion of previously certified gasoline and blendstock. (i) 
    Any refiner who uses previously certified reformulated or conventional 
    gasoline, or blendstock that previously has been included in compliance 
    calculations under Sec. 80.102(e)(2), to produce gasoline at a 
    refinery, shall exclude the previously certified gasoline and 
    blendstock for purposes of demonstrating compliance with the standards 
    under Sec. 80.101(b).
        (ii) In order to accomplish the exclusion required in paragraph 
    (g)(5)(i) of this section, the refiner shall either:
        (A) Determine the volume and properties of blendstock used at the 
    refinery, and use the compliance calculation procedures in paragraph 
    (g)(5)(iii) of this section; or
        (B) Determine the volume and properties of the previously certified 
    gasoline and the previously certified blendstock used at the refinery, 
    and the volume and properties of gasoline produced at the refinery, and 
    use the compliance calculation procedures in paragraph (g)(5)(iv) of 
    this section.
        (iii) (A) Determine the volume and properties of each batch of 
    blendstock used at the refinery, and of oxygenate blended with a 
    refinery's gasoline under paragraph (d)(4)(ii) of this section, with 
    the exception of previously certified
    
    [[Page 37395]]
    
    blendstock, using the procedures in paragraph (i) of this section.
        (B) Determine the blendstock volume fraction (F) based on the 
    volume of blendstock, and the volume of gasoline with which the 
    blendstock is blended, using the following equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.014
    
    Where:
    
    F = blendstock volume fraction
    Vb = volume of blendstock
    Vg = volume of gasoline with which the blendstock is 
    blended.
    
        (C) For each parameter required by the complex model, calculate the 
    parameter value that would result by combining, at the blendstock 
    volume fraction (F), the blendstock with a gasoline having properties 
    equal to the refinery's or importer's baseline, using the following 
    formula:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.015
    
    Where:
    
    CPj = calculated value for parameter j
    BAPj = baseline value for parameter j
    BLPj = value of parameter j for the blendstock
    j = each parameter required by the complex model
    
        (1) The baseline value shall be the refinery's ``summer'' or 
    ``winter'' baseline, based on the ``summer'' or ``winter'' 
    classification of the gasoline produced as determined under paragraph 
    (g)(3)(iii) of this section. In the case of a refinery that is 
    aggregated under paragraph (h) of this section, the refinery baseline 
    shall be used, and not the aggregate baseline.
        (2) The sulfur content and oxygen wt% adjustment required under 
    paragraph (g)(3)(i) of this section shall use a gasoline specific 
    gravity of 0.749 for ``summer'' gasoline and of 0.738 for ``winter'' 
    gasoline.
        (3) In the case of ``summer'' gasoline, where the blendstock is 
    ethanol and the volume fraction calculated under paragraph 
    (g)(5)(iii)(B) of this section is equal to or greater than 0.015, the 
    value for RVP shall be 1.0 psi greater than the RVP calculated using 
    the equation in this paragraph (g)(5)(iii)(C).
        (D) Using the summer or winter complex model, as appropriate, 
    calculate the exhaust toxics and NOX emissions performance, 
    in mg/mi, of:
        (1) A hypothetical gasoline having properties equal to those 
    calculated in paragraph (g)(5)(iii)(C) of this section (HEP); and
        (2) A gasoline having properties equal to the refinery's or 
    importer's baseline (BEP).
        (E) Calculate the exhaust toxics and NOX equivalent 
    emissions performance (EEP) of the blendstock, in mg/mi, using the 
    following equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.016
    
    Where:
    
    EEPJ = equivalent emissions performance of the blendstock 
    for emissions performance j
    BEPJ = emissions performance j of a gasoline having the 
    properties of the refinery's baseline.
    HEPJ = emissions performance j of a hypothetical blendstock/
    gasoline blend
    F = blendstock volume fraction
    J = exhaust toxics or NOX emissions performance
    
        (F) For each blendstock batch, the volume, and exhaust toxics and 
    NOX equivalent emissions performance (EEP), shall be 
    included in the refinery's compliance calculations.
        (G)(1) The portions of a blendstock batch used to produce 
    ``summer'' and ``winter'' gasoline, as determined in paragraph 
    (g)(3)(iii) of this section, shall be treated as separate batches for 
    purposes of this paragraph (g)(5)(iii).
        (2) In the case of oxygenates or butane blended with a refinery's 
    gasoline under paragraph (d)(4)(ii) of this section, the oxygenate or 
    butane volume blended during a maximum of one month may be treated as a 
    single batch for purposes of this paragraph (g)(5)(iii).
        (iv)(A) For each batch of previously certified gasoline or 
    blendstock received that is used to produce conventional gasoline:
        (1) Determine the volume and properties using the procedures in 
    paragraph (i) of this section;
        (2) In the case of previously certified gasoline, determine the 
    exhaust toxics and NOX emissions performance using the 
    summer or winter complex model, as appropriate.
        (3) In the case of previously certified blendstock, determine the 
    exhaust toxics and NOX equivalent emissions performance 
    using the procedures in paragraph (g)(5)(iii) of this section.
        (4) Include the volume and emissions performance, as a negative 
    volume and a negative emissions performance, in the refinery's 
    compliance calculations for exhaust toxics and NOX.
        (B) Determine the volume and properties, and exhaust toxics and 
    NOX emissions performance, for each batch of conventional 
    gasoline produced at the refinery using previously certified gasoline 
    or blendstock, and include each batch in the refinery's compliance 
    calculations for exhaust toxics and NOX without regard to 
    the presence of previously certified gasoline or blendstock in the 
    batch.

    of a group;
    
    [[Page 37396]]
    
        (B) The data for any refinery is included in only one compliance 
    calculation;
    
    and
    
        (C) Where more than one person meets the definition of refiner for 
    a refinery, the refinery may not be aggregated with any other refinery 
    unless the same persons meet the definition of refiner for . each 
    refinery in the aggregation.
    * * * * *
        (4) Where any refinery that has been included in an aggregation is 
    transferred to another refiner, or is shut down:
        (i) The aggregation requirements and baselines calculated under 
    Sec. 80.91(f)(4) shall apply;
        (ii) The aggregated baseline for the refiner who transfers or shuts 
    down the refinery shall be calculated for the averaging period during 
    which the refinery is transferred or is shut down using an adjusted 
    baseline volume for the refinery calculated using the following 
    equation:
    [GRAPHIC] [TIFF OMITTED] TP11JY97.017
    
    Where:
    
    ABV = adjusted baseline volume
    BV = baseline volume for the transferred or shut down refinery
    Days = number of days during the averaging period the party was the 
    refiner of the refinery or that the refinery was in operation
    
        (iii) In the case of a transferred refinery:
        (A) The new refiner's aggregation election shall be made for the 
    averaging period during which the refinery is transferred, and shall 
    apply for all subsequent averaging periods;
        (B) If the new refiner elects to aggregate the refinery, the 
    aggregated baseline for the new refiner shall be calculated for the 
    averaging period during which the refinery is transferred using an 
    adjusted baseline volume for the transferred refinery calculated using 
    the equation in paragraph (h)(4)(ii) of this section; and
        (C) Each refiner of a transferred refinery shall demonstrate 
    compliance for the gasoline produced during the period it was the 
    refiner of the refinery.
        (i) Sampling and testing. (1) * * *
        (i) * * *
        (C) Sampling under this paragraph (i)(1)(i) shall follow the 
    requirements of Sec. 80.47.
    * * * * *
        (iii) Retain a minimum of 330 ml of every sample analyzed under 
    paragraph (i)(1)(i)(A) of this section for not less than 30 days from 
    the date of production or import, and provide this remaining sample to 
    the Administrator's authorized representative upon request.
        (2) In the case of oxygenate that is included in a refinery's 
    compliance calculations under paragraph (d)(4) of this section the 
    refiner may use the properties of the pure oxygenate instead of 
    sampling and testing each oxygenate batch, provided that the refiner 
    obtains documents from the oxygenate supplier that state the purity of 
    any oxygenate used.
        (3) An importer who imports conventional gasoline into the United 
    States by truck may meet the sampling and testing requirements under 
    paragraph (i)(1) of this section as follows.

    section, based on the baselines applicable to the importer for these 
    two periods; or
        (B) May be met for all gasoline during a calendar year on the basis 
    of the annual baseline applicable to the importer.
        (iii)(A) The importer must demonstrate that every gallon of 
    imported gasoline meets the applicable conventional gasoline standards, 
    through test results of samples of the gasoline contained in the 
    storage tank from which the trucks used to transport gasoline into the 
    United States are loaded.
        (B) The frequency of this sampling and testing must be subsequent 
    to each receipt of gasoline into the storage tank, or immediately prior 
    to each transfer of gasoline to the importer's truck.
        (C) The testing must be for each applicable parameter specified 
    under Sec. 80.65(e)(2)(i), using the test methods specified under 
    Sec. 80.46.

    that reflects the quality of each truck load of gasoline that is 
    imported into the United States.
        (iv)(A) The importer must conduct separate programs of periodic 
    quality assurance sampling and testing of the gasoline obtained from 
    each truck-loading terminal, to ensure the accuracy of the terminal

    independent under Sec. 80.65(f)(2)(iii) to test the sample) for the 
    parameters specified under Sec. 80.65(e)(2)(i) using the test methods 
    specified under Sec. 80.46, and the results must correlate with the 
    terminal's test results within the ranges specified under 
    Sec. 80.65(e)(2)(i).
        (D) The frequency of quality assurance sampling and testing must be 
    at least one sample for each fifty of an importer's trucks that are 
    loaded at a terminal, or one sample per month, whichever is more 
    frequent.

    commercial grade shall include the butane in compliance calculations 
    based on the properties specified in paragraph (i)(4)(i) of this 
    section;
        (iv) Any refiner who blends butane for which the refiner has 
    documents from the butane supplier which demonstrate the butane is non-

    procedures in this subpart F, the attestor may foot to subtotals on a 
    sample basis in those instances where subtotals (e.g., page totals) 
    exist. In such instances, the total should be footed from the subtotals 
    and the subtotals should be footed on a test basis using no less than 
    25% of the subtotals.
        (j) Gasoline Treated as Blendstock, or GTAB, means imported 
    gasoline that is excluded from the import facility's compliance

    test method, the correlation factors and results shall be included as 
    part of the laboratory analysis. For refineries or importers that 
    produce reformulated gasoline or RBOB and use the 100% independent lab 
    testing, the laboratory analysis shall consist of the results reported 
    to the refinery or importer by the independent lab. Where assumed 
    properties are used (e.g., for butane) the assumed properties may serve 
    as the test results. In the case of attest engagements for in-line 
    blending operations under Sec. 80.132, the term laboratory analysis 
    shall include both the ``primary analysis'' results under

    represented by the refiner/importer/oxygenate blender as having been 
    provided to the transferee, and that reflect the transfer of ownership 
    or physical custody of gasoline or blendstock (e.g., invoices, 
    receipts, bills of lading, manifests, and/or pipeline tickets).
        (n) Reporting period means the time period relating to the reports 
    filed with EPA by the refiner, importer, or oxygenate blender, and 
    generally is the calendar year.
        (o) Tender means the transfer of ownership or physical custody of a 
    volume of gasoline or other petroleum product all of which has the same 
    identification (reformulated gasoline, conventional gasoline, RBOB, and 
    other non-finished-gasoline petroleum products), and characteristics 
    (time and place of use restrictions for reformulated gasoline and 
    RBOB).
        36. Section 80.127 is amended by revising paragraph (a) to read as 
    follows:

        40. Section 80.131 is added to subpart F to read as follows:
    
    
    Sec. 80.131  Agreed upon procedures for GTAB, certain conventional 
    gasoline imported by truck, previously certified gasoline used to 
    produce gasoline, and butane blenders.
    
        (a) Attest procedures for GTAB. The following are the attest 
    procedures to be carried out in the case of an importer who imports 
    gasoline classified as blendstock (or ``GTAB'') under the terms of 
    Sec. 80.83:
        (1) Obtain a listing of all GTAB volumes imported for the reporting 
    period. Agree the total volume of GTAB from the listing to the 
    inventory reconciliation analysis under Sec. 80.132.
        (2) Obtain a listing of all GTAB batches reported to EPA by the 
    importer. Agree the total volume of GTAB from the listing to the GTAB 
    volumes reported to EPA. Note that the EPA report includes a notation 
    that the batch is not included in the compliance calculations because 
    the imported product is GTAB. Also, agree these volumes to the Import 
    Summary received from the U.S. Customs Service.
        (3) Select a sample, in accordance with the guidelines in 
    Sec. 80.127, from the listing of GTAB batches obtained in paragraph 
    (a)(2) of this section, and for each GTAB batch selected perform the 
    following:
        (i) Trace the GTAB batch to the tank activity records. From the 
    tank activity records, determine the volumes of conventional gasoline 
    and of RFG produced. Agree the volumes from the tank activity records 
    to the batch volume reported to the EPA as reformulated or conventional 
    gasoline.
        (ii) Agree the location of the refinery represented by the tank 
    activity records obtained in paragraph (a)(3)(i) of this section for 
    the gasoline produced from GTAB, to the location that the GTAB arrived 
    in the U.S. or at a facility to which GTAB is directly transported from 
    the import facility using records representing location (e.g., US 
    Customs Service entry records). Using product transfer records, trace 
    volumes transported from the import facility directly to the refinery 
    as applicable.
        (iii) Obtain tank activity records for all batches of GTAB received 
    and blended. Using the tank activity records, determine whether the 
    GTAB was received into an empty tank, or into a tank containing other 
    GTAB imported by that importer or finished gasoline of the same 
    category as the gasoline that will be produced using the GTAB.
        (iv) Using the tank activity records obtained under paragraph 
    (a)(3)(iii) of this section, determine the volume of any tank bottom 
    (beginning tank inventory) that is previously certified gasoline before 
    GTAB is added to the tank. Using lab reports, batch reports, or product 
    transfer documents, determine the properties of the tank bottom.
        (v) Determine whether the properties and volume of gasoline 
    produced using GTAB were determined in a manner that excludes the 
    volume and properties of any gasoline that previously has been included 
    in any refiners or importers compliance calculations, as follows:
        (A) Note documented tank mixing procedures.
        (B) Determine the volume and properties of the gasoline contained 
    in
    
    [[Page 37401]]
    
    the storage tank after blending is complete. Mathematically subtract 
    the volume and properties of the previously certified gasoline to 
    determine the volume and properties of the GTAB plus blendstock added. 
    Agree the volume and properties of the GTAB plus blendstock added to 
    the volume reported to EPA as a batch of gasoline produced; or
        (C) In the alternative, using the tank activity records, note that 
    only GTAB and blending components were combined, and that no gasoline 
    was added to the tank. Agree the volumes and properties of the 
    shipments from the tank after the GTAB and blendstock are added, 
    blended, and sampled and tested, to the volumes and properties reported 
    to the EPA by the refiner.
        (vi) Obtain the importer's laboratory analysis for each batch of 
    GTAB selected, and agree the properties listed in the corresponding 
    batch report submitted to the EPA, to the laboratory analysis.
        (b) Attest procedures for certain truck imports. The following 
    procedures are to be carried out in the case of an importer who imports 
    conventional gasoline into the United States by truck using the 
    sampling and testing option in Sec. 80.101(i)(3) (``Sec. 101(i)(3) 
    truck imports'').
        (1) Obtain a listing of all volumes of Sec. 101(i)(3) truck imports 
    for the reporting period. Agree the total volume of Sec. 101(i)(3)

    under Sec. 80.132.
        (2) Obtain a listing of all Sec. 101(i)(3) truck import batches 
    reported to EPA by the importer. Agree the total volume of 
    Sec. 101(i)(3) truck imports from the listing to the volume of 
    Sec. 101(i)(3) truck imports reported to EPA. Also, agree these totals 
    to the Import Summary received from the U.S. Customs Service.
        (3) Select a sample, in accordance with the guidelines in 
    Sec. 80.127, from the listing obtained in paragraph (b)(2) of this 
    section, and for each Sec. 101(i)(3) truck import batch selected 
    perform the following:
        (i) Obtain the copy of the terminal test results for the batch, 
    under Sec. 80.101(i)(3)(iii)(A), and determine that the sample was 
    analyzed using the test methods specified in Sec. 80.46, and agree the 
    terminal test results to the batch properties reported to EPA; and
        (ii) Obtain tank activity records for the terminal storage tank 
    showing receipts, discharges, and sampling, and determine that the 
    sample under paragraph (b)(3)(i) of this section was collected 
    subsequent to the most recent receipt into the storage tank.
        (4) Obtain listings for each terminal where Sec. 101(i)(3) truck 
    import gasoline was loaded, of all quality assurance samples collected 
    by the importer, and for each terminal select a sample in accordance 
    with the guidelines in Sec. 80.127 from the listing. For each quality 
    assurance sample selected perform the following:
        (i) Determine that the sample was analyzed by the importer or by an 
    independent laboratory, and that the analysis was performed using the 
    test methods specified in Sec. 80.46;
        (ii) Obtain the terminal's test results that correspond in time to 
    the time the quality assurance sample was collected, and agree the 
    terminal's test results with the quality assurance test results; and
        (iii) Determine that the quality assurance sample was collected 
    within the frequency specified in Sec. 80.101(i)(3)(iv)(D).
        (c) Attest procedures for previously certified gasoline. The 
    following procedures are to be carried out in the case of a refiner who 
    uses previously certified gasoline (PCG) under the requirements of 
    Sec. 80.65(i).
        (1) Obtain a listing of all batches of PCG received at the refinery 
    during the reporting period. Agree the total volume of PCG from the 
    listing to the inventory reconciliation analysis under Sec. 80.132.
        (2) Obtain a listing of all PCG batches reported to EPA by the 
    refiner. Agree the total volume of PCG from the listing of PCG received 
    to the volume of PCG reported to EPA.

        (b) Batch listings. (1) Obtain a listing of all batches of 
    reformulated gasoline and RBOB produced during the prior year under an 
    in-line blending exemption, and test the mathematical accuracy of the 
    volumetric calculations contained in the listing.
        (2) Select a representative sample of the reformulated gasoline and 
    RBOB batches produced under an in-line blending exemption using the 
    guidelines specified under Sec. 80.127, and for each batch selected 
    obtain the laboratory analysis results for the batch, as identified in 
    paragraph (a)(2) of this section.
        (3) The procedures specified in paragraphs (c) and (d) of this 
    section shall be carried out for each batch identified in paragraph 
    (b)(2) of this section, and for each parameter that is subject to, or 
    that is used to calculate an emissions performance that is subject to, 
    a standard specified in Sec. 80.41 for the batch.
        (c) Primary analysis results. (1) Identify the laboratory analysis 
    that formed the basis for the refiner's report to EPA for the parameter 
    (the ``primary analysis'') and report this result as a finding;

    to be used to confirm the accuracy of the primary analysis (the 
    ``confirmatory analysis''), and for each parameter complete the 
    procedures specified in this paragraph (d).
        (1) Where the confirmatory analysis results are from an analyzer 
    that operates continually or with great frequency as part of the in-
    line blending operation (``on-line'' analysis results), identify twelve 
    confirmatory analysis results as follows:
        (i) Separate the blend into twelve equal time segments;
        (ii) For each time segment, identify the mid-point of the time 
    segment; and
        (iii) Identify the on-line analysis result that reflects the 
    quality of gasoline being produced most close to the mid-point of the 
    time segment.
        (2) Where the confirmatory analysis results are from samples that 
    are collected during the blending operation and analyzed at a separate 
    laboratory (``off-line'' analysis results), select a representative 
    sample of the off-line confirmatory analysis results using the 
    guidelines specified in Sec. 80.127 as confirmatory analysis results.

    (b)(2) of this section the difference between any primary analysis 
    result and the corresponding confirmatory analysis result under 
    paragraph (d) of this section is greater than the value for that 
    parameter specified in Sec. 80.65(e)(2)(i), the following procedure 
    shall be followed:
        (1) Select an additional sample from the listing of batches under 
    paragraph (b)(1) of this section using the guidelines specified under 
    Sec. 80.127 based on the total number of batches, but in a manner that

    Sec. 80.133  Agreed-upon procedures for refiners and importers.
    
        The following are the minimum attest procedures that shall be 
    carried out for each refinery and importer. Agreed upon procedures may 
    vary from the procedures stated in this section due to the nature of 
    the refiner's or importer's business or records, provided that any 
    refiner or importer desiring to use modified procedures obtains prior 
    approval from EPA.

    importer's reports (except for batch reports) filed with the EPA as 
    required by Secs. 80.75 and 80.105 for the reporting period.
        (2) In the case of a refiner's report to EPA that represents 
    aggregate calculations for more than one refinery, obtain the refinery-
    specific volume and property information that was used by the refiner 
    to prepare the aggregate report. Foot and crossfoot the refinery-
    specific totals and agree to the values in the aggregate report. The 
    procedures in paragraphs (b) through (m) of this section then are 
    performed separately for each refinery.

    and
        (2) Agree the beginning and ending inventory amounts in the 
    analysis to the refinery's or importer's inventory records. If the 
    analysis shows no production of conventional gasoline or if the 
    refinery or importer represents under paragraph (l) of this section 
    that it has a baseline less stringent or equal to the statutory 
    baseline, the analysis may exclude non-finished-gasoline petroleum 
    products.
        (3) Report as a finding the volume totals for each product type.
        (c) Listing of tenders. For each product type other than non-

    should provide for each tender the volume shipped and other information 
    as needed to distinguish tenders. Perform the following:
        (1) Foot to the volume totals per the listings; and
        (2) For each product type listed in the inventory reconciliation 
    analysis obtained in paragraph (b) of this section, agree the volume 
    total on the listing to
