    ACTION: Final rule.
    
    -----------------------------------------------------------------------
    
    SUMMARY: Title IV of the Clean Air Act (the Act) authorizes the 
    Environmental Protection Agency (EPA or Agency) to establish the Acid 
    Rain Program. The purpose of the Acid Rain Program is to significantly 
    reduce emissions of sulfur dioxide and nitrogen oxides from utility 
    electric generating plants in order to reduce the adverse health and 
    ecological impacts of acidic deposition (or acid rain) resulting from 
    such emissions. On January 11 and March 23, 1993, the Agency 
    promulgated final rules governing permitting, the allowance system, 
    continuous emissions monitoring, excess emissions, and appeal 
    procedures. On December 27, 1996, the Agency published proposed 
    revisions to those rules, most of which revisions are addressed in 
    today's final rule.
        After considering its experience in applying the Acid Rain Program 
    rules since 1993, the Agency believes that the permitting, excess 
    emissions, and appeal procedures rules (as well as minor aspects of the 
    monitoring rule) can be streamlined and improved in order to reduce the 
    burden on utilities, State and local permitting authorities, and EPA. 
    Today's final rule revisions streamline the Acid Rain Program while 
    still ensuring achievement of its statutory goals of reducing sulfur 
    dioxide and nitrogen oxides emissions.
        In addition, EPA is revising the sulfur dioxide allowances for one 
    unit. Each allowance authorizes the emission of one ton of sulfur 
    dioxide. Under the Acid Rain Program, utility units (i.e., fossil fuel-
    fired boilers or turbines) are allocated annual allowances and must not 
    emit sulfur dioxide in excess of the amount authorized by the 
    allowances that they hold. Today's final rule revises one unit's 
    allowances pursuant to a settlement agreement. In a future final 
    action, EPA will act on the other allowance revisions that were set 
    forth in the December 27, 1996 proposed rule.
    
    EFFECTIVE DATE: November 24, 1997.

    I. General
    
        A significant number of the revisions in the December 27, 1996 
    proposal did not receive any comment. Most of the proposed revisions, 
    including all on which comment was received, are discussed in this 
    preamble. Unless otherwise stated below, revisions are adopted in 
    today's final rule for the reasons discussed in the proposal.
    
    II. Part 72: Applicability of and Exemptions From Acid Rain Program
    
    A. Applicability
    
        The proposal included two types of revisions of the existing rule. 
    First, the definition of ``power purchase commitment'' was revised to 
    extend to three years the period by which a letter of intent must have 
    resulted in execution of a power sales agreement. Second, minor 
    revisions were made to the procedure for petitioning for a 
    determination by the Administrator on the applicability of the Acid 
    Rain Program to a unit. Supportive comment was received on the first 
    revisions, and no comment was received on the second. The revisions are 
    therefore adopted in today's rule.
    
    B. Exemptions
    
    1. New Units Exemption
        Section 72.7 of the existing rule provides an exemption from most 
    Acid Rain Program requirements for new units that serve generators with 
    a total capacity of 25 MWe or less and that combust clean fuels. The 
    proposal made
    
    [[Page 55461]]
    
    several types of revisions in order to streamline the new units 
    exemption. With the changes discussed below,1 revisions are 
    adopted in today's rule for the reasons discussed here and in the 
    proposal.
    ---------------------------------------------------------------------------
    
        \1\ In addition, today's rule adds language clarifying that the 
    requirement that a unit serve one or more generators with total 
    nameplate capacity of 25 MWe or less during the period of the 
    exemption does not apply to the time before the unit commenced 
    commercial operation. Today's rule also adds language, under 
    ``Special Provisions'', to reiterate the fact (reflected in 
    Sec. 72.7(a)) that an exempt unit must continue to meet the 
    requirements (e.g., the sulfur content limits for its fuels) 
    throughout the duration of the exemption. Another addition in 
    today's rule is language clarifying that when the exemption is lost, 
    the unit must comply with Acid Rain permitting and monitoring 
    requirements, starting after the loss of the exemption (e.g., 
    starting on the first date on which the unit is no longer exempt). 
    Similar language is added to the retired units and industrial 
    utility-units exemption provisions.
    ---------------------------------------------------------------------------
    
        First, the requirement for the combustion of clean fuels at the 
    unit was revised in the proposal. While the existing rule requires that 
    only fuel with a sulfur content 0.05 percent or less by weight be 
    combusted, the proposal stated that the unit must burn gaseous fuel 
    with an annual average sulfur content of 0.05 percent or less by weight 
    and nongaseous fuel with an annual average sulfur content of 0.05 
    percent or less by weight. Commenters supported the revisions and 
    explained that the existing rule was unduly restrictive. These 
    revisions are adopted in today's rule.
        The proposal also set forth revised procedures for determining 
    annual average sulfur content by weight for gaseous and nongaseous 
    fuel. The proposal eliminated provisions mandating the use of listed 
    methods for measuring sulfur content but included provisions concerning 
    the required frequency of sampling. The proposal provided explicitly 
    that the owners and operators of the unit bear the burden of proving 
    compliance with the sulfur content requirement. Commenters supported 
    these revisions but suggested that EPA state that any ``recognized 
    industry standard such as an ASTM method would be acceptable.'' 
    Commenters also urged that the rule state that a unit that burns only 
    diesel fuel meeting the requirements of diesel fuel for motor vehicles 
    be assumed to meet the limits on sulfur content of fuel.
        The proposed revisions are adopted in today's rule. Under the final 
    rule, since methods for measuring sulfur content are not specified, the 
    Agency will evaluate on a case-by-case basis the information provided 
    by the owners and operators of a unit on sulfur content. In order to 
    ensure that owners and operators understand that they must use a 
    reasonable method to determine sulfur content, the final rule adopts 
    language from section 412 concerning emission monitoring and states 
    that the method of determining sulfur content must provide information 
    that is reasonably precise, reliable, accessible, and timely. EPA 
    anticipates that owners and operators will meet their burden of proof 
    by using a method that is generally recognized in the industry (such as 
    the applicable ASTM method set forth in the existing rule), is 
    applicable to the unit, and is consistent with the other provisions 
    (e.g., sampling frequency requirements) of today's rule.
        Further, EPA recognizes that diesel fuel for motor vehicles is 
    required under Sec. 80.29 to have a sulfur content of 0.05% by weight. 
    Commenters have suggested that such diesel fuel should be assumed to 
    meet the sulfur content limit without any testing. One commenter stated 
    that the testing by the unit owner was burdensome and duplicative of 
    testing by the fuel supplier.
        However, not all diesel fuel is required to meet the sulfur content 
    limit; only diesel fuel for use in motor vehicles must meet the limit 
    under Sec. 80.29. 40 CFR 80.29(a)(1)(i). A significant amount of diesel 
    fuel is produced for other uses (e.g., as fuel for electric generation 
    by utilities) has a higher sulfur content than mandated for diesel fuel 
    for motor vehicles. Petroleum Supply Annual 1996, Vol. 1 at 51, Table 
    17 (Energy Information Administration, June 1997) (indicating that 
    about 37% of 1996 U.S. distillate production (which is primarily diesel 
    fuel as defined in Sec. 72.2) had a sulfur content above 0.05% by 
    weight).2 Moreover, the higher-sulfur diesel fuel is used by 
    many utility units that combust diesel fuel. For example, during 1996 
    and the first half of 1997, diesel fuel with a sulfur content of 0.05% 
    or less by weight accounted for only about 13% of the total heat input 
    for affected units that used diesel fuel and were required to report 
    the sulfur content of their fuel to EPA. Most of the diesel fuel used 
    had a much higher sulfur content; diesel fuel with more than twice the 
    sulfur content (i.e., over 0.10% sulfur by weight) accounted for about 
    81% of such total heat input.3
    ---------------------------------------------------------------------------
    
        \2\ Relatively little distillate fuel oil is imported into the 
    U.S., and most of it has a sulfur content exceeding 0.05%. Id. at 
    55, Table 20.
        \3\ Report to Docket: Diesel Fuel Use of Units Required to Use 
    Fuel Sampling Under part 75, appendix D (September 16, 1997).
    ---------------------------------------------------------------------------
    
        In contrast, virtually all commercially available natural gas in 
    the U.S. has sulfur content at or below 0.05% by weight. Because of the 
    toxic effects of hydrogen sulfide and its corrosive effect on pipeline 
    and customer equipment, pipelines generally provide pipeline 
    transportation or distribution service only for natural gas with a very 
    low hydrogen sulfide content (e.g., 0.25 to 0.30 grain per 100 standard 
    cubic feet), which results in total sulfur content far below 0.05% by 
    weight. See, e.g., H. Dale Beggs, Gas Production Operations at 204-5, 
    209-11, and 227 (1984); and 49 CFR 192.475(c) (provision, in U.S. 
    Department of Transportation minimum safety standards for natural gas 
    pipelines, limiting the hydrogen sulfide content of gas ``stored in 
    pipe-type or bottle-type holders'' to 0.25 grain per 100 standard cubic 
    feet).
        Since diesel fuel is widely available that does not meet the sulfur 
    content limit, diesel fuel must be treated like any other fuel that is 
    combusted at an exempt new unit and that could potentially exceed the 
    limit. The owners and operators of the unit combusting the fuel must 
    demonstrate that the limit is being met using the results of reliable 
    testing methods consistent with the sampling and other requirements of 
    today's rule. Of course, under today's rule, the owners and operators 
    are not required to conduct the testing themselves. EPA will consider 
    testing by fuel suppliers in determining whether the owners and 
    operators have met their burden of proof.
        Second, the proposal streamlined the procedure for obtaining a new 
    units exemption and reduced the burden imposed by the procedure on 
    owners and operators and permitting authorities. The existing rule 
    required owners and operators of a unit to submit an application and 
    for permitting authorities to provide notice and opportunity for 
    comment before issuing an exemption. The proposal made the obtaining of 
    an exemption largely automatic so long as the capacity, annual fuel 
    use, and recordkeeping requirements are met. Under the proposal, owners 
    and operators of a unit meeting these requirements must submit a 
    statement to the permitting authority (and, if EPA is not the 
    permitting authority, to EPA) that the unit meets, and will continue to 
    meet, the requirements for the exemption. The proposal states that a 
    new units exemption is effective on January 1 of the first full 
    calendar year for which the unit meets the exemption requirements and 
    that the statement must be submitted by December 31 of such year. In 
    short, where the end-of-year submission deadline and other requirements 
    for an exemption are met, the exemption will cover the entire year in 
    which the submission was made. The
    
    [[Page 55462]]
    
    proposed revisions are adopted in today's rule.
        The proposal established some additional procedures for the 
    relatively few new units that were allocated allowances.4 
    The owners and operators of such units must submit a statement (similar 
    to the one for units without allocations) stating that the owners and 
    operators are surrendering the allowances, and proceeds from the 
    auction of allowances, starting with the first year for which the unit 
    is exempt. Under the proposal, the exemption for a unit allocated 
    allowances is effective on January 1 of the first year for which the 
    Administrator actually deducts the full allowance allocation and 
    actually receives the full amount of auction proceeds. Commenters 
    contended that this ``unfairly'' makes the exemption contingent on an 
    event (i.e., the deduction of allowances) beyond the control of the 
    owners and operators. Allegedly, the exemption should be contingent 
    only on submission of the statement surrendering allowances and 
    proceeds.
    ---------------------------------------------------------------------------
    
        \4\ While the proposal referred to allowances allocated under 
    Table 2 or 3 of subpart B of part 73, today's rule simply refers to 
    allowances allocated under that subpart. Under part 73 as currently 
    organized, all allocations to new units are included in the tables. 
    Since in the future EPA may reorganize the allowance allocation 
    information that is currently presented in two separate tables, 
    today's rule adopts a more general reference to new-unit allowance 
    allocations.
    ---------------------------------------------------------------------------
    
        EPA notes that the only issue is the date on which the exemption 
    becomes final. Once the Administrator actually makes the necessary 
    allowance deductions and receives the proceeds, the exemption runs 
    starting from January 1 of the year for which the unit meets the 
    requirements (e.g., fuel sulfur limits and allowance and proceeds 
    surrender) for this exemption. The difficulty with making the exemption 
    effective when the surrender statement is submitted is that there is no 
    guarantee that the unit's allowance account actually has sufficient 
    allowances to deduct or that the proceeds are actually available to and 
    received by the Administrator.
        In order to ensure that the actual deduction of allowances in the 
    unit's Allowance Tracking System account is not unduly delayed, the 
    final rule requires that, within 5 business days of receiving the 
    owners' and operators' surrender statement, the Administrator either 
    makes the allowance deductions or notifies the owners and operators 
    that there are insufficient allowances for the deductions. This is the 
    same period of time in which, under Secs. 73.52 and 73.53, the 
    Administrator must act on an allowance transfer request. The approach 
    adopted in today's rule accommodates both the concern that the 
    necessary number of allowances actually be available for deduction 
    before the exemption is effective and the concern that the 
    effectiveness of the exemption not be unnecessarily delayed.
        Finally, the proposal provided that a unit with a new units 
    exemption is not an ``affected unit'' and so does not need an operating 
    permit under part 70 or 71 unless such a permit is required because 
    non-title IV, federal requirements applicable to the unit. See 61 FR 
    68343. However, for the case where, because of non-title IV 
    requirements, the source at which the unit is located has or must have 
    an operating permit, the proposal did not exclude the new units 
    exemption from the general requirement to incorporate applicable 
    federal requirements in the operating permit. See 42 U.S.C. 
    7661a(b)(5)(A) and 7661c(a). The final rule adopts the proposed 
    provision and makes it clear that if, because of non-title IV 
    requirements, an operating permit is issued to the source, the new 
    units exemption must be reflected in that operating permit. In 
    particular, after the actions necessary for the new units exemption to 
    take effect have been completed (e.g., the receipt by the permitting 
    authority of a statement of exemption by the owners and operators of 
    the unit and the notification by the Administrator that he or she has 
    deducted any allowances, and received any allowance proceeds, required 
    to be surrendered), the permitting authority must add the provisions 
    and ongoing requirements of the exemption to any operating permit that 
    covers the source at which the unit is located. Consistent with the 
    elimination of the requirement for notice and comment on a new unit's 
    exemption, the addition of the exemption to the permit is an 
    administrative amendment. A written new units exemption issued under 
    the existing rule prior to revision by today's rule must similarly be 
    added to any operating permit.
        Under this approach, the exemption alone will not result in 
    issuance of an operating permit, but, if an operating permit would be 
    issued for the source in any event, that operating permit will include 
    the ongoing requirements imposed on the unit under the exemption. This 
    approach reasonably implements the concept that an operating permit 
    should include the applicable federal requirements for a source. For 
    the same reasons, analogous provisions are included in today's rule 
    with regard to the retired units exemption and the industrial-utility 
    units exemption.
    2. Retired Units Exemption
        Section 72.8 of the existing rule provides an exemption from Acid 
    Rain Program requirements for retired units. The proposal made several 
    types of revisions in order to streamline this retired units exemption. 
    First, while the existing rule required owners and operators of a unit 
    to submit an application for the exemption and for permitting 
    authorities to provide public notice and opportunity for comment before 
    issuing a final exemption, the proposal made the obtaining of an 
    exemption largely automatic so long as the unit is permanently retired. 
    Second, the proposal clarified that the exemption applies to most Acid 
    Rain Program requirements.
        No comments were received on these proposed revisions. In order to 
    make it clear that only Phase I or Phase II units, and not opt-in units 
    under part 74, are eligible for the retired units exemption, today's 
    rule states that the exemption applies to ``any affected unit (except 
    for an opt-in source)''. This exclusion of opt-in sources is consistent 
    with the existing provisions of part 74 that impose separate 
    requirements with regard to permanent shutdown of opt-in sources. See, 
    e.g., 40 CFR 74.46. In addition, to provide flexibility where a retired 
    unit has no allowance allocations and has not selected a designated 
    representative, the final rule allows a certifying official to submit 
    notice of the exemption to the permitting authority. For the reasons 
    discussed here and in the proposal, the revisions, as modified, are 
    adopted in today's rule.
    3. Industrial Utility-Units Exemption
        Scope of Exemption. In the proposal EPA established a new exemption 
    for certain industrial units that generate only incidental amounts of 
    electricity for sale. As explained in detail in the preamble of the 
    proposal, ``utility units'' (the entities subject to the Acid Rain 
    SO2 emission limitation and other requirements of the Acid 
    Rain Program) include, with certain exceptions, any unit serving a 
    generator that produced electricity for sale any time starting in 1985. 
    With certain exceptions (e.g., for cogenerators), an industrial unit 
    serving a generator that produced any amount of electricity for sale 
    (referred to hereinafter as simply an ``industrial utility-unit'') 
    5 is an affected unit under
    
    [[Page 55463]]
    
    the Acid Rain Program regardless of the amount of the sale relative to 
    the total generation by the generator and whether or not the sale is to 
    the general public or to a public utility for resale to the public. 
    Moreover, the requirement to hold allowances to cover SO2 
    emissions and to meet any applicable NOX emission limitation 
    under the Acid Rain Program applies to all emissions from the unit, not 
    simply the portion that might be attributed to generation of the 
    electricity sold.
    ---------------------------------------------------------------------------
    
        \5\ The proposal referred to these units as simply ``industrial 
    units''. In order to minimize confusion between these units and 
    industrial boilers not used in generation of electricity for sale, 
    and because generation of electricity for sale makes industrial 
    units ``utility units'' under title IV, the final rule refers to the 
    units as ``industrial utility-units''.
    ---------------------------------------------------------------------------
    
        Despite the applicability of the requirement to hold allowances, 
    EPA has not allocated allowances to industrial utility-units that might 
    have qualified for allowance allocations under section 405 of the Act, 
    including some units whose owners submitted timely comments relating to 
    allowance allocations. On March 23, 1993, EPA issued notices stating 
    that such industrial utility-units would not be included in the 
    National Allowance Database, on which allowance allocations are based, 
    because EPA ``believe[d]'' that the units were not affected units. 58 
    FR 15720, 15727 (1993). On the same date, EPA also issued a final 
    allowance allocation list that allocated allowances only to units then 
    ``believed'' to be affected units. 58 FR 15634, 15641 (1993). EPA 
    stated that no allowances would be allocated to units that were 
    subsequently determined to be, or that subsequently became, affected 
    units. Id.
        In light of these circumstances, EPA proposed a limited exemption 
    from the Acid Rain Program for industrial utility-units that served, 
    any time starting in 1985, a generator that produced electricity for 
    sale. First, the industrial utility-unit must have no owner or operator 
    of which the principal business is electricity sale, transmission, or 
    distribution or that is a public utility subject to State or local 
    utility regulation.6 Such unit must not be a cogeneration 
    unit since cogeneration units already are covered by an express 
    exemption in the title IV. Further, on or before March 23, 1993, the 
    owners or operators of the unit must have entered into an 
    interconnection agreement (and any related power purchase agreement) 
    with a public utility requiring that the generator served by the unit 
    produce electricity for sale only for incidental sales of electricity 
    to that public utility. Moreover, in 1985 and any year thereafter, the 
    generator served by the unit must have actually produced only 
    incidental electricity sales for the utility, as required under the 
    interconnection agreement and any related power purchase agreement. 
    Incidental sales were defined as sales not exceeding the lesser of 10 
    percent of the generating output capacity of the generator or 10 
    percent of the actual annual electric output of the generator.
    ---------------------------------------------------------------------------
    
        \6\ In order to prevent the requirement from being circumvented 
    through the position of the owner or operator in the corporate 
    structure, the proposal stated that no owner or operator, subsidiary 
    or affiliate or parent company of the owner or operator, or 
    combination thereof could have such a principal business. Consistent 
    with this approach, the final rule also applies this to any division 
    of the owner or operator.
    ---------------------------------------------------------------------------
    
        The proposal established a petition and notice-and-comment 
    procedure for owners or operators to apply for the exemption and for 
    the Agency to review and approve or disapprove the exemption. If, after 
    approval of the exemption, any of the conditions for obtaining the 
    exemption are no longer met, the exemption terminates automatically. 
    The proposal, as changed below, is adopted for the reasons discussed 
    here and in the proposal.7
    ---------------------------------------------------------------------------
    
        \7\ In the proposal, EPA relied on the Report For Docket: 
    Industrial Units (October 31, 1996). In the report, EPA estimated 
    the number of industrial utility-units in the U.S. that may quality 
    for an industrial utility-units exemption under Sec. 72.14 and their 
    total annual SO2 and NOX emissions. One 
    commenter asserted that the report overestimated the emissions for 
    two units owned by the commenter. Assuming the accuracy of the 
    commenter's emission estimates, the total annual SO2 and 
    NOX emissions estimates for industrial utility-units are 
    reduced by about 10%, i.e., to about 41,000 tons of SO2 
    and 17,000 tons of NOX. This is not a significant change 
    and does not affect EPA's determinations concerning the industrial 
    utility-units exemption.
    ---------------------------------------------------------------------------
    
        All parties commenting on the new industrial utility-units 
    exemption supported the concept of such an exemption. However, these 
    commenters objected to various, specific provisions. First, commenters 
    claimed that EPA should ``totally'' exempt industrial utility-units 
    without regard to the amount of electricity sold by an industrial 
    utility-unit and/or without regard to whether the unit was 
    contractually obligated to sell electricity on or before March 23, 
    1993. Allegedly, industrial utility-units not qualifying for the 
    exemption will incur significant costs ``not related'' to the 
    objectives of title IV. It was argued that if industrial utility-units 
    that cannot meet the criteria of the rule are not exempt, 
    ``agreements'' providing for sales by industrial utility-units to 
    utilities may be ``discontinued'', forcing utilities to ``look 
    elsewhere for their emergency and backup power needs.'' It was also 
    argued that the costs of complying with the Acid Rain Program ``will 
    exceed the benefits of the limited reductions to be achieved by the 
    regulations'' since the estimated amount of SO2 emissions is 
    small relative to the annual 8.95 million ton cap for utility units. 
    Since industrial utility-units are allegedly subject to the nationwide 
    cap of 5.60 million tons on total annual SO2 emissions by 
    ``industrial sources'', regulation of industrial utility-units under 
    the existing Acid Rain regulations was claimed to be unnecessary.
        However, EPA begins with the fact, undisputed by any commenter, 
    that Congress included non-cogeneration industrial utility-units in the 
    Acid Rain Program and thus under the annual 8.95 million ton cap for 
    SO2 emissions and under applicable NOX emission 
    limitations. See 61 FR 68344. Further, although the preamble of the 
    proposal stated that industrial utility-units are also under the 5.60 
    million ton cap for ``industrial sources'' under section 406(b) of the 
    Clean Air Act Amendments of 1990, EPA now believes, on further 
    consideration, that industrial utility-units (which served, any time 
    starting in 1985, a generator that produced electricity for sale) are 
    not covered by the latter cap.
        Section 406(b) of the Clean Air Act Amendments of 1990 states that 
    if SO2 emissions from ``industrial sources * * * may 
    reasonably be expected to reach levels greater than 5.60 million tons 
    per year,'' the Administrator may take actions ``to ensure that such 
    emission do not exceed'' the cap. 42 U.S.C. 7651 note. From section 
    406(a), it is clear that the definition of ``industrial source'' in 
    section 402 of the Clean Air Act applies. Under section 402, an 
    ``industrial source'' is:
    a unit that does not serve a generator that produces electricity, a 
    ``nonutility unit'' as defined in this section, or a process source 
    as defined in section 410(e). 42 U.S.C. 7651a(24)
    
    As discussed above, an industrial utility-unit is a unit that is not 
    owned or operated by a utility but that served, anytime starting in 
    1985, a generator that produced electricity for sale and therefore is a 
    utility unit under section 402(17). Such a unit does not fall within 
    any of the three groups of units that are defined as ``industrial 
    sources''.8 Consequently, the units that are under 
    consideration in this rulemaking for
    
    [[Page 55464]]
    
    inclusion in the industrial utility-units exemption are not covered by 
    the 5.60 million ton cap. Contrary to commenters, the Clean Air Act 
    Amendments of 1990 do not give EPA the ``option'' of regulating 
    industrial utility-units under section 406. In contrast, Congress 
    exempted certain cogeneration facilities from the Acid Rain Program 
    (e.g., the 8.95-million-ton cap) and included them in the 5.60-million-
    ton cap. Under section 402(17)(C) and (25), exempt cogeneration 
    facilities are excluded from the definition of ``utility unit'' and so 
    are ``nonutility'' units covered by the ``industrial source'' cap.
    ---------------------------------------------------------------------------
    
        \8\ Section 406(a) also states that ``industrial sources'' 
    include units subject to section 405(g)(6), i.e., certain qualifying 
    facilities and independent power production facilities that are 
    exempt from title IV. The reference in section 406(b) to units 
    ``subject to section 405(g)(5)'' is an inadvertent error that should 
    be read as citing section 405(g)(6). See National Annual Industrial 
    Sulfur Dioxide Emission Trends 1995-2015, EPA-454-R-95-001, at ES-2 
    (EPA 1995). Industrial utility-units are not exempt under section 
    405(g)(6).
    ---------------------------------------------------------------------------
    
        This reinforces the conclusion that industrial utility-units are 
    intended to be covered by the Acid Rain Program and leads to the 
    conclusion that a blanket exemption for all industrial utility-units is 
    inconsistent with the overall regulatory scheme under title 
    IV.9 Exempting all industrial utility-units, without regard 
    to the amount of their electricity sales or to when the sales became 
    contractually obligated, would result in a potentially increasing group 
    of existing and future units that would generate electricity for sale 
    but would be outside both the utility unit and the ``industrial 
    source'' caps. Particularly since the ongoing changes in the structure 
    of the electric industry make it difficult to predict how many 
    industrial utility-units there may be in the future and how they may be 
    used, EPA rejects such an open-ended exemption from both 
    caps.10 Moreover, commenters supporting a blanket exemption 
    ignore the fact that the Acid Rain Program is aimed at reducing both 
    SO2 emissions and NOX emissions. To the extent 
    that existing coal-fired industrial utility-units are Group 1 (i.e., 
    dry bottom wall-fired or tangentially fired) or Group 2 (i.e., cell 
    burner, cyclone, wet bottom, or vertically fired) boilers, exempting 
    them removes the applicability of the Group 1 or Group 2 NOX 
    emission limits, which in some cases may be the only NOX 
    limits for these boilers under the Act.
    ---------------------------------------------------------------------------
    
        \9\ EPA rejects as speculative and irrelevant the commenter's 
    suggestion that title IV may be amended in a way that would require 
    non-exempt industrial utility-units to make additional, 
    ``prohibitively expensive'' reductions.
        \10\ Even if the ``total'' exemption were limited to the 
    specific possible industrial utility-units identified thus far by 
    EPA (see Report to Docket: Industrial Units (October 31, 1996)), the 
    amount of generation and emissions covered by a ``total'' exemption 
    could increase in the future. Moreover, the commenters suggested no 
    basis for limiting a ``total'' exemption to those tentatively 
    identified industrial utility-units if other units are subsequently 
    found to meet the ``total''-exemption criteria.
    ---------------------------------------------------------------------------
    
        EPA also rejects, as unsupported and speculative, the claim that 
    subjecting industrial utility-units to Acid Rain Program requirements 
    will make interconnection agreements and related power sales agreements 
    between such units and utilities economically prohibitive. EPA agrees 
    that industrial companies may have more difficulty than utilities (at 
    least under the current scheme of utility rate regulation) in passing 
    through the costs of the Acid Rain Program. However, that is a far cry 
    from concluding that electricity sales by existing industrial utility-
    units would cease or that no new industrial utility-units would 
    contract to make such sales.
        EPA therefore maintains that, if there is to be any exemption for 
    industrial utility-units, the exemption must be strictly limited in 
    order to resolve the specific problem set forth in the preamble of the 
    proposal. That problem is that some industrial utility-units have only 
    incidental activities (i.e., electricity sales) bringing the entire 
    operation of the unit under the Acid Rain Program and that these units 
    likely qualified for, but were not allocated, allowances. Strictly 
    limiting the exemption to address this problem will minimize the 
    potential environmental impact of this resolution on SO2 and 
    NOX emissions and will better harmonize the exemption with 
    the basic regulatory scheme under title IV. In fact, without the 
    specific limits on the exemption set forth in today's rule based on the 
    magnitude of electricity sales and the time period when electricity 
    sales first became contractually required, EPA would reconsider whether 
    any exemption for industrial utility-units should be established.
        As an alternative to a blanket exemption for industrial utility-
    units, one commenter suggested modifying the definition of ``incidental 
    sales of electricity'' so that units selling up to one-third (rather 
    than up to 10 percent, as under the proposal) of their electric 
    generation to utilities could qualify as exempt industrial utility-
    units. Allegedly, limiting sales to up to one-third of annual electric 
    generation would be consistent with the statutory exemption for 
    cogeneration facilities. Under section 402(17)(C) and Sec. 72.6(b)(4), 
    a cogeneration facility that supplies to a utility, on an annual basis, 
    an amount of electricity not exceeding one-third of its potential 
    electrical output capacity or 219,000 MWe-hrs is an unaffected unit and 
    is not subject to the Acid Rain Program. The commenter supported 
    limiting industrial utility-units to annual electricity sales equal to 
    the lesser of one-third of capacity or one-third of actual generation.
        Reflecting that the rationales for the industrial utility-units 
    exemption and the statutory cogeneration facility exemption are not 
    identical, today's rule does not make the requirements for the two 
    types of exemptions identical. On one hand, the cogeneration facility 
    exemption reflects Congressional intent, manifest in section 402(17)(C) 
    of the Act, that certain cogeneration facilities be entirely exempt 
    from the Acid Rain Program whether or not they had contracted before 
    enactment of title IV to provide electricity at a fixed price. 
    Presumably, this is because, by using the same steam both for electric 
    generation and industrial purposes, cogeneration facilities are 
    inherently more efficient than other units that generate electricity. 
    See 40 CFR 72.2 (defining ``cogeneration unit'' as unit producing 
    electricity and useful thermal energy ``through sequential use of 
    energy''). On the other hand, the industrial utility-units exemption 
    addresses the category of industrial utility-units, which were intended 
    by Congress to be subject to the Acid Rain Program but, with regard to 
    certain individual units, were not allocated allowances for which they 
    likely qualified. They lack the sequential use of energy that makes 
    cogeneration facilities inherently more efficient. As discussed above, 
    EPA maintains that the industrial utility-units exemption should, under 
    these circumstances, be more narrowly drawn than the provisions for 
    exempting cogeneration facilities. Consequently, EPA disagrees with the 
    approach of using the limit on electricity sales by exempt cogeneration 
    facilities in setting the limit on electricity sales by exempt 
    industrial utility-units.
        In the proposal, the industrial utility-units exemption is limited 
    to units that were contractually obligated as of March 23, 1993 to make 
    only incidental sales of electricity to utilities. The proposal defines 
    ``incidental sales'' as sales not exceeding 10 percent of either 
    nameplate capacity or total actual generation because that level seemed 
    to be consistent with the general level of historical electricity sales 
    by the type of unit intended to be covered by the exemption. This 
    approach limits the exemption by restricting both the number of units 
    covered by the exemption and the amount of electricity sales to 
    historical levels and does not allow expansion beyond those levels. 
    None of the commenting owners of units potentially qualifying for the 
    industrial utility-units exemption claimed that they had actually made, 
    in any past year, electricity sales in excess
    
    [[Page 55465]]
    
    of the 10 percent limit or that the 10 percent limit is 
    unrepresentative of historical levels. EPA maintains that it is 
    appropriate to impose on the industrial utility-units exemption a limit 
    reflecting historical levels and that, on their face, electricity sales 
    as high as one-third of total generation cannot be regarded as simply 
    incidental to the operation of the unit involved. For these reasons, 
    while choosing a 10-percent level as the cutoff point for ``incidental 
    sales''--like choosing any specific cutoff point--is to some extent 
    arbitrary, EPA maintains that the chosen level is reasonable. Today's 
    rule, like the proposal, defines ``incidental electricity sales'' as an 
    amount of electricity sales that does not exceed the smaller of 10 
    percent of the nameplate capacity of the generator served by the unit 
    times 8,760 hours per year or 10 percent of the actual annual electric 
    output of that generator.
        Today's rule also continues to impose the incidental-electricity-
    sales limit on sales starting in 1985 and continues to require that the 
    contractual obligation to make such sales must have been in place on 
    March 23, 1993. One commenter objected to having ``two different 
    deadlines'' and argued that only sales starting in 1993 should have to 
    meet the incidental-electricity-sales limit. EPA rejects this approach.
        Under the industrial utility-units exemption, EPA considers the 
    electricity sales of the unit starting in 1985 because that is 
    analogous to the approach taken by Congress in section 402(17) in 
    determining what units are utility units that are subject to the Acid 
    Rain Program. With certain exceptions, any unit that at any time 
    starting in 1985 or thereafter serves a generator that produces 
    electricity for sale is a ``utility unit'' subject to the Acid Rain 
    Program. 42 U.S.C. 7651a(17)(A). In crafting the industrial utility-
    units exemption, EPA reasonably takes a parallel approach of 
    considering actual sales starting in 1985. Actual sales before 1985 
    will not be considered. EPA sees no basis for the commenter's 
    suggestion of ignoring any non-incidental electricity sales from 1985 
    to 1993. In essence, EPA is requiring that, in order to be exempt, a 
    unit must have maintained its character as an industrial utility-unit 
    making only incidental sales throughout the period generally used to 
    determine applicability of the Acid Rain Program.
        The rationale for the ``second deadline'' in the industrial 
    utility-units exemption--i.e., the requirement that there be, as of 
    March 23, 1993, a contractual obligation to make incidental electricity 
    sales--is set forth in detail in the proposal and is adopted here. 61 
    FR 68346. This requirement also makes it likely that the unit was 
    either (i) in commercial operation as of November 15, 1990 or (ii) was 
    under construction by December 31, 1990 and therefore qualified for, 
    but was not allocated, allowances in Phase II. See 42 U.S.C. 7651d(a)-
    (f) and (h)-(i) (allowances for existing units) and (g) (allowances for 
    units under construction and operating by specified deadlines).
        Termination of exemption. Under the proposal, a unit's industrial 
    utility-units exemption terminates automatically once any of the 
    original requirements for granting the exemption are no longer met. 
    Commenters raised concern that the proposal terminates the exemption if 
    the contractual agreement that requires incidental electricity sales by 
    the unit, and on which the granting of the exemption was originally 
    based, expires or is amended. A particular agreement may have a 
    termination date even though the parties intend for the relationship to 
    continue. Further, an agreement may be modified directly or through 
    replacement by a new agreement, e.g., in order to change the names of 
    the parties or the electricity prices. According to commenters, the 
    exemption should not be terminated so long as there is not an 
    obligation to sell more than an incidental amount of electricity.
        EPA understands the concern that replacement of the interconnection 
    agreement on which an exemption is based (or of the power purchase 
    agreement related to the interconnection agreement) by a follow-on 
    agreement that continues to require the same amount of electricity 
    sales should not result in termination of the exemption. EPA also 
    recognizes a similar concern with regard to amendment of the 
    interconnection agreement or power purchase agreement. On one hand, the 
    rule should provide for some flexibility allowing agreements to be 
    modified or replaced so long as the underlying electricity sales 
    obligation of the industrial utility-unit is not altered in a way that 
    undermines the original basis for the unit's exemption. On the other 
    hand, EPA is concerned that this flexibility should not have the effect 
    of allowing expansion of the unit's exemption beyond its original 
    scope. For example, just as a unit that as of March 23, 1993 did not 
    serve a generator required to produce electricity for sale and that 
    begins after that date to be involved in electricity sales is not 
    exempt, an exempt unit should not be able to expand its involvement in 
    electricity sales after March 23, 1993 and retain the exemption. 
    Finally, EPA believes it must consider that future modifications or 
    replacements of agreements will be taking place in the context of 
    restructuring of the electric industry, where utilities may be 
    restructured and renamed.
        In order to meet all of these concerns, today's rule provides that, 
    in applying the automatic-termination provisions of the exemption, the 
    interconnection agreement (and related power purchase agreement) and 
    any successor agreement will be considered. For example, the proposal 
    stated that if the interconnection agreement on which the exemption is 
    based expires or terminates and the generator served by the unit 
    continues to produce electricity for sale, the exemption for the unit 
    terminates. Under today's rule, if that interconnection agreement is 
    replaced or supplemented by a ``successor agreement'', the expiration 
    or termination of the original agreement will not cause termination of 
    the exemption. Today's rule defines ``successor agreement'' in a way 
    that is aimed, on one hand, at requiring the unit to continue to meet 
    the basic requirements for the exemption and taking account of future 
    electric industry restructuring and, on the other hand, at preventing 
    this flexibility from being used to expand beyond the original scope of 
    the exemption when it was approved.
        A ``successor agreement'' is defined as an agreement that modifies, 
    replaces, or supersedes the interconnection agreement or related power 
    purchase agreement on which the exemption was originally based. 
    Further, a ``successor agreement'' must be between owners and operators 
    of the unit and another party (which may be the same party as in the 
    original agreement) that (i) is principally in the electric utility 
    business or is a public utility subject to State or local jurisdiction 
    and (ii) is obligated to sell electricity to the owners and operators 
    of the unit. In addition, the ``successor agreement'' must require the 
    generator served by the unit to produce electricity for sale only for 
    incidental electricity sales to that party. Finally, the total amount 
    of electricity that the generator served by the unit is required to 
    produce for sale under all such contracts that are in effect (i.e., the 
    interconnection agreement, related power purchase agreement, and any 
    successor agreement) must not exceed the amount that such generator was 
    required to produce for sale under the original interconnection 
    agreement and related power purchase agreement on which the exemption 
    was initially based.
        Procedural and other issues. Under the proposal, a unit seeking an
    
    [[Page 55466]]
    
    industrial utility-units exemption must submit a petition to the local 
    permitting authority. The processing of the petition is similar to that 
    for an Acid Rain permit. However, once an exemption is approved, it has 
    no uniform, fixed term and continues in effect unless and until it is 
    automatically terminated. Commenters claimed that the process of 
    petitioning for the exemption would be burdensome. They noted that the 
    proposal removed the requirements to apply for the new units or retired 
    units exemption and argued that the industrial utility-units exemption 
    should similarly be made ``self-executing''.
        When the new units and retired units exemptions were first adopted 
    by rule, the regulations required submission of petitions for the 
    exemptions, processing by the permitting authority using the permit 
    notice-and-comment procedures, and renewal every five years. The 
    December 27, 1996 proposal and today's rule make those exemptions self-
    executing for the most part. With some exceptions, owners and operators 
    of units meeting the fairly straightforward requirements of the new 
    units or retired units exemptions need only notify the permitting 
    authority and EPA of their qualification for the exemption.
        In the case of the industrial utility-units exemption, EPA has 
    decided that it is necessary to require the submission of a petition 
    and processing by the permitting authority. This is a newly established 
    exemption, with which the Agency has had no experience. Moreover, in 
    determining whether to establish the exemption, EPA has found it 
    difficult to obtain information on which units might qualify. See 
    Report to Docket: Industrial Units (October 31, 1996). In addition, 
    determination of whether a unit qualifies for the exemption is not as 
    straightforward as the determination of qualification for the new units 
    or retired units exemption. Qualification for an industrial utility-
    units exemption depends, in part, on interpretation of interconnection 
    and power purchase agreements. Further, particularly in light of other 
    provisions of today's rule that streamline the permit processing 
    procedures and thus also apply to processing of a petition for 
    industrial utility-units exemption, EPA maintains that the petition and 
    review requirements for the exemption are not unduly burdensome on 
    either the unit owners and operators or the permitting authorities. 
    Today's rule requires a one-time review process in that once approved, 
    the exemption continues in effect without the need for renewal.
        One final issue raised by a commenter (Zinc Corporation of America) 
    is whether industrial utility-units that do not qualify for an 
    industrial utility-units exemption should be allocated allowances. 
    Allegedly, such units qualify for allowances but were not allocated any 
    due to EPA's ``oversight in allowance allocation''.
        The difficulty with this argument is that it ignores the fact that 
    EPA has previously specified deadlines by which parties claiming that 
    an erroneous failure to allocate allowances to a unit were required to 
    submit such claims and necessary supporting information to EPA. As 
    explained in the proposal (61 FR 68345), EPA issued in July 1992 the 
    Adjunct Data File listing units of ``nontraditional utilities''. 57 FR 
    30034, 30040 (July 7, 1992). EPA indicated that the units might or 
    might not be affected units and that, in any event, it lacked 
    sufficient information on which to base any allowance allocation. Id. 
    Further, EPA gave notice that if the data necessary for allowance 
    allocation was not provided by September 8, 1992 for ``a unit that may 
    be affected now or in the future'', the unit would not be allocated 
    allowances. Id. Moreover, believing that it had corrected all timely 
    identified errors in the data and resulting allocations, EPA stated in 
    the March 23, 1993 notice on final allowance allocations that no 
    allowances will be allocated to any affected unit that was not 
    allocated allowances in that notice. 58 FR 15634, 15641 (March 23, 
    1993).
        Neither Zinc Corporation of America nor the predecessor-owner (St. 
    Joe Minerals Corporation) of the units now owned by Zinc Corporation of 
    America submitted any data or any objection to the lack of allowance 
    allocations for the units. The only companies that have units 
    identified by EPA as potentially industrial utility-units and that 
    submitted any comments concerning allowance allocations were LTV Steel 
    Mining Company and Ford Motor Company. Both companies claimed that 
    their units were not affected units, and neither has ever objected to 
    the lack of allowance allocations.
        Thus, there is no basis for allocating allowances now or in the 
    future to industrial utility-units, as suggested by the commenter, if 
    EPA ultimately determines that any such units do not qualify for the 
    industrial utility-units exemption.11 Such units are treated 
    like any other unit that has not been allocated allowances and becomes 
    an affected unit after that date: No allowances will be allocated. 
    EPA's approach of declining to allocate allowances when the deadline 
    for submission of information for allowance allocation is missed has 
    been upheld by the courts. Texas Municipal Power Agency v. EPA, 89 F.3d 
    858. 872-73 (1996).
    ---------------------------------------------------------------------------
    
        \11\ EPA stresses that it has made no determination at this time 
    on the qualification of these companies' units for the industrial 
    utility-units exemption and will await submission of the necessary 
    applications before making any determination. None of the companies 
    that commented stated that it could not meet the proposed exemption 
    requirements.
    ---------------------------------------------------------------------------
    
    III. Part 72: Interaction of Acid Rain Permitting and Title V
    
    A. Relationship Between Acid Rain Rules and Parts 70 and 71
    
        The proposal attempted to clarify the extent to which the Acid Rain 
    rules apply in lieu of provisions of parts 70 and 71, which address 
    permitting by State permitting authorities and by the Administrator 
    under title V of the Act. No comments were received on these revisions. 
    The revisions are adopted in today's rule with some changes. The 
    language in several sections of the proposal stating that the Acid Rain 
    rules ``supersede'' provisions of parts 70 or 71 is removed from the 
    final rule because of concern that such language might cause confusion 
    as to whether parts 70 and 71 remain in effect at all.
        Instead, today's Sec. 72.60 clarifies that part 72 governs, 
    notwithstanding the requirements of part 71, and the list of specific 
    procedural matters that part 72 governs is clarified and augmented so 
    that the list includes all matters covered by subparts C, D, E, F, and 
    H of part 72.12 The list of specific matters to which part 
    71 still applies is also clarified. Further, today's Sec. 72.70 retains 
    the language in the existing rule stating that subpart G governs to the 
    extent that the subpart is ``inconsistent'' with part 70. Upon 
    reconsideration of the language, EPA concludes that this existing 
    language is reasonably clear, particularly with the revisions in 
    Sec. 72.72 reducing the number of differences between subpart G and 
    part 70. EPA also notes that the existing language avoids any potential 
    confusion about the overall effectiveness of part 70.
    ---------------------------------------------------------------------------
    
        \12\ For similar reasons, the same general approach is used in 
    Sec. 72.80, which states that subpart H, rather than part 70 or 71, 
    governs revisions of Acid Rain permit provisions.
    ---------------------------------------------------------------------------
    
    B. State Authority to Administer and Enforce Acid Rain Permits
    
        Under the proposal, a State becomes responsible for administering 
    and enforcing Acid Rain permits for affected sources if the State has 
    an operating permits program approved under part
    
    [[Page 55467]]
    
    70 and to the extent the State Acid Rain regulations are accepted by 
    the Administrator. The proposal also established a procedure for 
    withdrawal of the Acid Rain Program from a State where the 
    Administrator determines that the State is not adequately administering 
    or enforcing the program.
        Today's rule adopts the revisions, with several changes. Under the 
    proposal, the Administrator accepts all or a portion of State Acid Rain 
    regulations through issuance of a notice in the Federal Register. 
    Particularly since the State regulations will then become part of the 
    State title V operating permits program, EPA believes that notice and 
    opportunity for public comment should be provided before the 
    Administrator issues a final acceptance or rejection of all or a 
    portion of the State regulations. This approach is consistent with the 
    requirement in part 70 that notice and opportunity for public comment 
    be provided on the Administrator's approval or disapproval of a State 
    operating permits program under title V. See 40 CFR 70.4(e). Today's 
    rule includes language that imposes a notice-and-comment requirement 
    but is flexible enough to allow use of a direct final procedure under 
    which, for example, the proposed and final acceptance of State 
    regulations are issued in simultaneous notices and the acceptance 
    becomes automatically final if no significant, adverse comments are 
    timely submitted.
        Further, the proposal revised the provision concerning the date by 
    which a State permitting authority must reopen Phase II Acid rain 
    permits to add Acid Rain NOX requirements. The existing 
    provision requires the permits to be reopened by January 1, 1999 but is 
    unclear as to whether this is the deadline for completion, or simply 
    commencement, of the reopening procedure. In order to clarify the 
    provision and ensure that State permitting authorities have sufficient 
    time to process the permits, the proposal stated that the reopening 
    must be completed by July 1, 1999.
        Commenters objected to the July 1, 1999 completion deadline on the 
    ground that utilities need more than 6 months to plan for compliance 
    with the NOX terms of their Acid Rain permits. No comment 
    was received supporting the Agency's concern that State permitting 
    authorities might need additional time beyond January 1, 1999 to 
    complete the reopening of the permit. Further, as discussed elsewhere 
    in this preamble, today's rule includes provisions that enable State 
    permitting authorities to expedite permit processing, e.g., the 
    provisions for elimination of newspaper notice and for use of direct 
    proposed procedures. By further example, today's rule provides that any 
    EPA-approved early election plan that has not been terminated must be 
    added to the Phase II permit through an administrative amendment, 
    rather than through a notice-and-comment procedure. This reflects the 
    fact that Sec. 76.8, governing early election plans, requires a State 
    permitting authority to approve, as part of the Phase II permit, any 
    ongoing early election plans previously approved by EPA. These 
    streamlining provisions will reduce the administrative burden on the 
    State permitting authorities.
        Consequently, today's rule retains the January 1, 1999 deadline and 
    makes it clear that the reopening of the permit to add NOX 
    requirements must be completed by that deadline. By its terms, the 
    January 1, 1999 deadline for adding the NOX provisions only 
    applies to the extent that the provisions were included in a timely, 
    complete permit application concerning NOX emissions. EPA 
    notes that, under Sec. 76.9(b)(2), such permit application must be 
    submitted by January 1, 1998 and that, where the State permitting 
    authority with jurisdiction over the unit has responsibility for 
    issuing Acid Rain permits covering NOX, the submission 
    should be made to that State permitting authority.
        Finally, language is added (e.g., to Sec. 72.73(b)(1) and 
    Sec. 72.74(a)) to make it clear that the State permitting authority 
    issues Acid Rain permits to the extent that it has State Acid Rain 
    regulations, accepted by EPA, that apply to the sources involved and to 
    the Acid Rain requirements involved. For example, if accepted State 
    Acid Rain regulations include the Acid Rain emissions limitation for 
    SO2 but not the emissions limitations for NOX by 
    the applicable deadline under Sec. 72.73, EPA has the flexibility to 
    determine whether the State permitting authority will be responsible 
    for issuing Acid Rain permits covering both SO2 requirements 
    under part 72 and NOX requirements under part 76.
    
    C. Required Elements for State Acid Rain Program
    
        The existing rule set forth the criteria for approval of a State 
    operating permit program under title V and acceptance of the State Acid 
    Rain regulations. The proposal eliminated or modified several of the 
    criteria in the existing rule because EPA believed that they were 
    unnecessary or redundant. Comments were received on only three of these 
    revisions. With the changes discussed below, all the revisions are 
    adopted in today's rule for the reasons discussed here and in the 
    proposal.
        First, the existing rule required State permitting authorities to 
    give written notice of draft permits to specified persons and also to 
    provide notice in a newspaper or State publication. The proposal gave 
    State permitting authorities the option of foregoing newspaper or State 
    publication notice of draft permits that require only that a unit meet 
    the standard SO2 or NOX emission limitations, a 
    NOX averaging plan, or a NOX early election plan. 
    Commenters supported this revision, which is adopted in today's rule.
        Second, the proposal gave State permitting authorities the option 
    of using what was referred to as a ``direct final'' procedure for 
    issuing Acid Rain permits. Under the procedure, a State permitting 
    authority issues simultaneously a draft permit and a proposed permit. 
    If no significant, adverse comments are received, the proposed permit 
    is deemed to be issued and, after the period for review by the 
    Administrator, the State permitting authority issues the final permit. 
    Commenters supported this option and urged that EPA clarify that it 
    applies to permit revisions as well as permit issuance. EPA notes that 
    the procedure is misnamed in the proposal in that the permit that is 
    issued in the absence of significant, adverse comment is a ``proposed 
    permit'' that is still subject to the Administrator's review. 
    Consequently, today's rule refers to this option as the ``direct 
    proposed'' procedure and adopts the provision. 13
    ---------------------------------------------------------------------------
    
        \13\ Today's rule also removes language in Sec. 72.72(b)(1)(iv) 
    stating that after the comment period on a draft permit, the State 
    permitting authority will issue or deny a proposed permit. Some 
    State permitting authorities have provided, with EPA's concurrence, 
    that the comment period on the draft permit and EPA's review of the 
    permit run concurrently so long as no adverse comment is received 
    and no change is made in the draft permit. The language in 
    Sec. 72.72 is removed in order to allow State permitting authorities 
    to take this approach, which reduces the length of the permitting 
    process, for Acid Rain permits.
    ---------------------------------------------------------------------------
    
        With regard to the use of the direct proposed procedure for permit 
    revisions, EPA notes that Sec. 72.81(c)(2) in the proposal and in 
    today's rule states that, with certain exceptions not relevant here, 
    permit modifications must be treated as permit applications. Consistent 
    with Sec. 72.81(c)(2), the procedures for permit issuance (including, 
    e.g., the direct proposed procedure) apply to permit modifications. 
    Similarly, permit issuance procedures apply to permit reopenings. 
    Because the other types of permit revisions, i.e., fast-track
    
    [[Page 55468]]
    
    modifications and administrative permit amendments, have their own 
    procedures set forth in the proposal and today's rule, the direct 
    proposed procedure does not apply to such revisions.
        Third, the proposal eliminated a provision in the existing rule 
    limiting the filing of State administrative or judicial appeals of an 
    Acid Rain permit to no more than 90 days from the issuance of the 
    permit. As a result, part 70, which imposes no limit on State 
    administrative appeals and limits judicial appeals to no more than 90 
    days from permit issuance, would govern appeals of Acid Rain permits. 
    40 CFR 70.4(b)(3)(xii); see also 59 FR 44460, 44516 (August 29, 1994) 
    (proposing to allow States to provide up to 125 days for judicial 
    appeals).
        Commenters objected to the removal of any limit on the periods for 
    State administrative appeals, and for judicial appeals, under part 72. 
    The commenters contended that, in the absence of a limit in part 72 (or 
    in part 70) on administrative appeals, owners and operators ``would 
    never be able to know whether their permits would be subject to 
    challenge''. However, the commenters ignored the fact that, in imposing 
    no federally mandated limit on State administrative appeals, part 72 
    leaves the matter to the States, which are highly likely to impose such 
    limits in the interests of finality and administrative efficiency. EPA 
    is not aware of any State operating permit programs that, to the extent 
    they provided for administrative appeal, failed to set a time limit on 
    the filing of administrative appeals. In short, the question here is 
    not whether to have any limit but rather whether to leave the matter 
    for the States or impose a federally mandated limit. EPA maintains that 
    it is preferable to allow each State flexibility to craft time limits 
    for Acid Rain appeals. Under this approach, each State can set a single 
    time limit appropriate for and applicable to all administrative 
    appeals--and also one for all judicial appeals--of the entire title V 
    operating permit, rather than having one set of time limits for an Acid 
    Rain permit and another set of time limits for the remaining portions 
    of the operating permit.
        The commenters contended that the Acid Rain permits are a ``stand-
    alone portion'' of the operating permit and so it would not be 
    confusing to have a different deadline for appealing the Acid Rain 
    portion and appealing the rest of the operating permit. EPA disagrees. 
    Although the Acid Rain permit is a separate portion of the operating 
    permit, State permitting authorities are likely, as a matter of 
    efficiency, to conduct notice and comment and other permitting 
    procedures for the rest of the operating permit at one time and to 
    issue a single, all inclusive operating permit, particularly since the 
    Acid Rain permit is likely to comprise a relatively small part of the 
    entire title V operating permit. In fact, in response to State concern 
    over how to coordinate the processing of the Acid Rain permit and the 
    operating permit, EPA has issued guidance on alternative approaches for 
    achieving coordination. See Guidance on Coordinating Title IV/Title V 
    Permitting Schedules (March 15, 1994). EPA believes that having a 
    single administrative appeal deadline and a single judicial appeal 
    deadline for the entire operating permit is simpler and less likely to 
    result in inadvertent failure to meet the applicable filing deadline.
        The commenters also alleged that the Acid Rain portion incorporates 
    new compliance obligations while the remainder of the operating permit 
    merely restates existing obligations. This, of course, depends on the 
    timing of the issuance of the operating permit. State permitting 
    authorities are allowed to phase in the issuance of operating permits 
    and new obligations may arise before issuance of, and therefore may be 
    included in, a given operating permit. Moreover, to the extent this 
    distinction applies, it is likely to apply only for the initial Phase 
    II Acid Rain permit; in most cases, a subsequent Acid Rain permit will 
    restate the obligations (e.g., the requirement to hold sufficient 
    allowances to cover SO2 emissions) already in the initial 
    Acid Rain permit.
        EPA concludes that, with regard to the question of limiting State 
    administrative and judicial appeals, the Acid Rain portions of 
    operating permits should not be treated any differently than the 
    remaining portions of operating permits. The provision in the proposal 
    is adopted in today's rule.
        In the proposal EPA noted that many States have already adopted 
    Acid Rain rules based on the existing rule. EPA stated that it expected 
    that, if rule revisions are adopted in final, States will incorporate 
    the revisions within 2 years after the promulgation of the final rule. 
    No comment was received on this approach, and EPA continues to believe 
    that this is a reasonable time frame. To the extent a State permitting 
    authority fails to incorporate the revisions in a timely manner, EPA 
    will consider whether the State is adequately administering and 
    enforcing the Acid Rain Program and may take action under Sec. 72.74 of 
    today's rule to administer all or a part of the Acid Rain Program for 
    sources located in the State.
    
    IV. Part 72: Miscellaneous Permitting Matters
    
    A. Definitions
    
        The proposal modified or eliminated several definitions. Only one 
    of the changes (i.e., the revised definition of ``submit or serve'' to 
    eliminate the requirement for use of certified mail) received comment 
    and that comment was supportive. The definition revisions, as modified 
    below, are adopted in today's rule.14
    ---------------------------------------------------------------------------
    
        \14\ One of the proposed definitions, ``State'', is modified in 
    today's rule. The proposed definition removed language, stating that 
    ``State'' has its conventional meaning where it is clear ``from the 
    context'', and listed one specific instance where the conventional 
    meeting would apply. Because there are several contexts in which the 
    conventional meaning applies, today's rule retains the formulation 
    in the existing rule. Thus, for example, in Sec. 72.40(b)(2) the 
    term ``State'' has its broader meaning (which includes the 
    jurisdiction of any non-federal permitting authority) while in 
    Sec. 72.22(e)(1)(i) ``State'' has its conventional meaning.
    ---------------------------------------------------------------------------
    
    B. Designated Representative
    
        The proposal included two types of revisions concerning designated 
    representatives. First, the procedures for selecting or changing the 
    designated representative or an alternate were simplified and made less 
    burdensome. Commenters supported the revisions, which are adopted in 
    today's final rule.
        Second, the proposal provided the option of selecting two alternate 
    designated representatives for an affected source in certain limited 
    circumstances. The proposal was aimed at providing flexibility for 
    sources with units located in more than one State that are in a 
    NOX averaging plan under Sec. 76.11 and that are subject to 
    two levels of management, one at the subsidiary operating company and 
    one at the parent company. In particular, as requested by a commenter, 
    the proposal allowed a multi-state utility holding company with a 
    NOX averaging plan covering units in two or more States to 
    designate for sources with units in the plan a single designated 
    representative at the holding company level and two alternates, one at 
    the management level and one at the operations level of the operating 
    company. Commenters supported the additional flexibility but suggested 
    certain changes to the proposal.15
    ---------------------------------------------------------------------------
    
        \15\ One commenter suggested that there is no basis for the 
    requirement in Sec. 76.11 that units in a NOX averaging 
    plan have the same designated representative. This suggestion is 
    outside the scope of the rulemaking. While it is unclear whether the 
    commenter intended to raise that issue here, EPA did not propose, 
    and is not considering here, such a change in Sec. 76.11.
    
    ---------------------------------------------------------------------------
    
    [[Page 55469]]
    
        The commenter that originally requested this type of provision in 
    the proposal expressed concern that the references in the proposal to a 
    holding company with multiple subsidiaries may become obsolete in light 
    of future restructuring of the electric industry. For example, a 
    holding company with subsidiaries operating generation facilities may 
    be restructured to include all generation facilities in a single 
    subsidiary. This commenter also was concerned that the proposal limited 
    the option of having two alternates to cases where the NOX 
    averaging plan covered all units operated by the subsidiaries. If any 
    units are covered by early election plans or have alternative emission 
    limitations and so are outside the NOX averaging plan, the 
    proposal would not apply. Other commenters echoed these concerns but 
    suggested that EPA allow any source to have two alternates, regardless 
    of whether the source has units that are in a NOX averaging 
    plan or are subject to management at both the subsidiary and parent 
    company levels.
        While retaining the general rule that a source must have one 
    designated representative and may have one alternate, EPA proposed 
    allowing two alternates in limited circumstances where it was shown 
    that such flexibility might be needed. The proposed provision, as 
    modified in today's rule, covers the only specific circumstance for 
    which a need for multiple alternates has been explained by commenters, 
    i.e., where units are in different States but in the same 
    NOX averaging plan and are subject to both subsidiary and 
    parent company management. While commenters make a general suggestion 
    that having two alternates gives greater assurance that a ``point of 
    contact'' for a source will be available ``at all times'', the 
    commenters do not claim that having one alternate has generally been 
    insufficient or point to any other specific circumstances where two 
    alternates are needed. EPA therefore declines to expand the provision 
    any further.
        For the reasons discussed here and in the proposal, today's rule 
    adopts the proposed provision, with changes to meet other concerns 
    stated by commenters. First, the provision expressly covers a unit 
    whose utility system is the subsidiary of a company (not necessarily a 
    ``holding company''). Second, the provision will cover cases where the 
    units in the NOX averaging plan are operated by a single 
    subsidiary or by two or more subsidiaries. Each unit must be in a 
    utility-system subsidiary of a company, but they may be in the same 
    such subsidiary. Third, the NOX averaging plan need not 
    include all units operated by subsidiaries of the company; instead the 
    plan must simply cover two or more units in more than one State.
    
    C. Compliance Plans
    
        The proposal revised the provisions concerning the submission of 
    substitution plans and reduced utilization plans in order to clarify 
    the deadlines and the procedures to be used. No comments were received, 
    and the revisions are adopted in today's rule.
        The proposal also revised the procedures for review of failed 
    repowering projects. No comments were received on the revisions, which 
    are adopted in today's rule.
        Finally, the proposal revised the deadline for activating 
    conditional repowering extension plans from December 31, 1997 to July 
    1, 1997. No comments were received. However, today's rule is being 
    published after July 1, 1997, and EPA has decided not to revise the 
    activation deadline retroactively.
    
    D. Federal Permit Issuance
    
        The proposal made several revisions to the federal permit issuance 
    procedures. For example, the period after which an Acid Rain permit 
    application received by EPA is deemed to be complete was lengthened 
    from 30 days to 60 days. This was done in order to be consistent with 
    part 71, under which the period applicable to operating permit 
    applications is 60 days. Commenters objected that this prolongs the 
    ``period of uncertainty'' over the completeness of the Acid Rain 
    application and stated that Acid Rain permitting ``generally proceeds 
    along a separate track'' from other title V permitting. However, the 
    commenters' assumption that the Acid Rain portion of the operating 
    permit is processed separately from the rest of the operating permit is 
    not necessarily correct. If the State permitting authority is generally 
    responsible for issuing title V operating permits but, because its Acid 
    Rain rules are not fully approved, EPA issues the Acid Rain permits, 
    then the Acid Rain permits may be processed separately. In cases where 
    EPA is responsible for issuing entire title V operating permits 
    (including the title IV portion), the title IV and title V procedures 
    may be coordinated as a matter of efficiency, particularly if EPA 
    delegates the title IV and title V permitting to the State. See 40 CFR 
    71.10 (delegation of permitting under title I); and 72.74(a)(2) of 
    today's rule (delegation of permitting under title IV). A single 
    completeness review (as well as a single notice and comment procedure) 
    may be conducted for the entire operating permit. EPA maintains that 
    the ability to coordinate Acid Rain permitting and title V permitting 
    and to realize potential efficiencies is enhanced by minimizing the 
    differences between Acid Rain permitting and title V permitting.
        Moreover, the Acid Rain portion of the operating permit is 
    generally relatively small compared to the entire title V permit 
    application. It is therefore logical to make the completeness review 
    period for the title IV permit conform to the 60-day period for title V 
    permits, rather than to shorten the title V completeness review period 
    to 30 days. While the period during which owners and operators are 
    uncertain about the completeness of Acid Rain permit applications will 
    be lengthened for 30 days, EPA maintains that the advantage of a 
    consistent completeness review period outweighs the relatively minor, 
    additional uncertainty.
        Further, the proposed rule altered the provision concerning the 
    time period within which a designated representative must respond to a 
    request for supplemental information by the Administrator. While the 
    existing rule set an automatic 30-day period for responding and allowed 
    the Administrator to lengthen the response period, the proposal stated 
    that a reasonable period would be set on a case-by-case basis by the 
    Administrator. A commenter objected on the ground that it is unlikely 
    that a period less than 30 days would be reasonable and that it would 
    generally be in the interest of a designated representative to respond 
    expeditiously. However, the commenter ignores the fact that there can 
    be significant, but readily remedied gaps or errors in the information 
    submitted to EPA in a permit application. Setting a minimum response 
    period of 30 days is likely to lengthen unnecessarily the permitting 
    process. In addition, while the Agency could treat applications with 
    such errors as incomplete and avoid the minimum 30-day response period, 
    EPA maintains that it is preferable to have the flexibility to set a 
    reasonable, short response period. This flexible approach both promotes 
    orderly and expeditious processing of permits and protects the 
    designated representative from unreasonable requests. This is also 
    preferable to the commenter's approach of assuming that designated 
    representatives will necessarily respond expeditiously and in a time 
    frame that meets the Agency's schedule for permit processing.
    
    [[Page 55470]]
    
    E. Permit Revision
    
        The proposal made several changes to the permit revision 
    procedures. Changes concerning permit reopenings received no comment 
    and are adopted in the final rule; changes concerning fast-track 
    amendments and administrative amendments are adopted as discussed 
    below.
        With regard to fast-track modifications, the proposal lengthened 
    the period within which a State permitting authority must act on a 
    fast-track modification of a permit from 30 to 60 days after the end of 
    the public comment period. Commenters objected claiming that there is 
    no evidence that State permitting authorities need more time and that 
    the revisions entitled to fast-track modification required little 
    exercise of administrative discretion and are unlikely to receive 
    public comment.
        EPA notes that, while a NOX averaging plan or plan 
    change may require little administrative discretion and elicit little 
    comment, the processing of other types of revisions (e.g., changes to 
    repowering plans or thermal energy plans) is more likely to involve 
    discretion or public comment. Further, the processing of Acid Rain 
    permits and permit revisions represents a very small portion of the 
    operating permit processing required of State permitting authorities 
    under title V. Reflecting the significant burden of operating permit 
    processing, part 70 allows State permitting authorities to take up to 
    18 months from receipt of a complete permit application to issue an 
    operating permit and a similar period to make significant modifications 
    to an existing operating permit. 40 CFR 70.7(a)(2) and (e)(4)(ii). By 
    comparison, a 90-day period (i.e., the 30-day comment period and 60 
    days after the end of the period) for completing a fast-track 
    modification is certainly expedited. EPA maintains that, in light of 
    the permitting burden faced by State permitting authorities, it is 
    preferable to set a more realistic, and yet still expedited, deadline 
    for action by State permitting authorities.
        With regard to administrative amendments, the proposal set forth 
    the amendment procedures in detail, rather than citing the procedures 
    in part 70. Further, the period for action on one administrative 
    amendment, an alternative emission limitation (AEL) demonstration 
    period, was lengthened from 30 days to 60 days after receipt of an AEL 
    demonstration period petition determined by the permitting authority to 
    meet all the requirements of Sec. 76.10. No comments were made on these 
    revisions, which are adopted in today's rule.
        In addition, the administrative amendment procedures were changed 
    to allow a permitting authority to correct minor errors in a permit on 
    its own motion. Noting that the proposed provision was not explicitly 
    limited to ``minor'' errors, commenters argued that notice should be 
    given to the designated representative before even minor changes are 
    made to the permit. In response to these concerns, today's rule 
    explicitly limits administrative permit amendments on the motion of the 
    permitting authority to corrections of typographical errors or 
    similarly noncontroversial changes (e.g., adding a new units or retired 
    units exemption for which the requirements were previously met). 
    Moreover, the rule requires that a permitting authority provide at 
    least 30 days' notice to the designated representative of the source 
    involved before making, on its own motion, any administrative permit 
    amendments. This approach will enable the permitting authority to 
    correct minor errors with minimal delay while providing the designated 
    representative the opportunity to commment.
        In order to make the reopening provision consistent with the 
    provision allowing a permitting authority to make administrative 
    amendments on its own motion, language is added to Sec. 72.85. This 
    language makes it clear that administrative amendment procedures, 
    rather than reopening procedures, may be used for typographical or 
    similar errors.
    
    F. Reduced Utilization Accounting
    
        The proposal made several changes in the reduced utilization 
    accounting provisions. Most of the changes received no comment or only 
    favorable comment and are adopted in today's rule. Commenters objected 
    to one change: The provision that, in accounting for the effect of heat 
    rate improvements on a Phase I unit's utilization, credit for such 
    improvements must be limited to the net effect of the improvements on 
    the unit's heat rate. According to the commenters, if a unit's heat 
    rate (i.e., Btu/Kwh) since the 1985-1987 base period deteriorates 
    (i.e., increases) and measures are taken that offset that 
    deterioration, the entire effect of the heat rate improvements should 
    be included in accounting for reduced utilization. The commenters 
    alleged that the statutory reduced utilization provision in section 
    408(c)(1)(B) of the Act establishes a ``baseline'' heat input, not a 
    ``baseline'' heat rate.
        In asserting that there is no connection between utilization in the 
    base period and heat input in the base period, the commenters ignore 
    the basic purpose of accounting for reduced utilization and heat rate 
    improvements. The purpose of the reduced utilization provisions is to 
    ensure that any increased emissions resulting from reducing utilization 
    of, and shifting generation from, Phase I units to units compensating 
    for the reduced utilization ``are accounted for in the allowance 
    system.'' 56 FR 63002, 63019 (December 3, 1991). Reduced utilization 
    ``as a result of * * * improved unit efficiency programs'' need not be 
    accounted for through allowance surrender because these programs 
    ``cause decreases in utilization without any shifts of generation to 
    unaffected units.'' 56 FR 63021. To the extent utilization (i.e., total 
    annual heat input in mmBtus) at a Phase I unit is reduced below the 
    baseline level because that unit has improved its heat rate after 1987 
    over the level reflected in the baseline utilization, there is no 
    increase in SO2 emissions and allowances need not be 
    surrendered. In this case, the Phase I unit is using less fuel because 
    it can produce a kilowatthour of electricity with less fuel and thus 
    less SO2 emissions.
        However, if the Phase I unit's heat rate deteriorates from the 
    level reflected in the unit's baseline utilization and heat rate 
    improvement measures are instituted after 1987 that bring heat rate 
    back to the level reflected in the baseline utilization, then the unit 
    is using the same amount of fuel to produce a kilowatthour of 
    electricity. In the latter case, the heat rate improvements made after 
    1987 do not account for the use of less fuel at the Phase I unit. Just 
    as heat rate improvements made before 1987 and reflected in baseline 
    utilization cannot account for utilization below baseline, heat rate 
    improvements made after 1987 that simply restore the heat rate to the 
    level reflected in the baseline cannot account for reduced utilization. 
    See 61 FR 68354. The same logic applies if a Phase I unit is attempting 
    to account for its reduced utilization through heat rate improvements 
    at another unit that simply restore the latter unit's heat rate to the 
    1987 level.
        Thus, contrary to the commenters' assertions, EPA did not simply 
    ``assume'' that limiting heat rate improvement to net improvement since 
    1987 is warranted. On the contrary, EPA explained, albeit in less 
    detail than in today's rule, the basis for the limitation. Id. 
    Moreover, the limitation is consistent with long-standing explanations 
    of the purpose of reduced utilization accounting, as discussed
    
    [[Page 55471]]
    
    above, and with other, regulatory provisions governing such accounting. 
    In particular, limiting heat rate improvement to net improvement since 
    1987 is analogous to the approach taken in the existing rule concerning 
    sulfur-free generation, which is not at issue here. Only the net 
    increase in current generation at a sulfur-free generator (i.e., the 
    increase in current generation over the sulfur-free generator's average 
    1985-1987 annual generation), not the increase from one year to the 
    next, is used to account for reduced utilization. See 40 CFR 
    72.91(a)(3)(iii); and 58 FR 3590, 3606-7 (January 11, 
    1993).16 The commenters' approach is therefore rejected as 
    inconsistent with the entire thrust of reduced utilization accounting, 
    and the proposed provision is adopted in today's rule.
    ---------------------------------------------------------------------------
    
        \16\ While EPA uses 1985-1987 average sulfur-free generation as 
    the bench mark for limiting the use of sulfur-free generation in 
    reduced utilization accounting, the proposal and today's rule use 
    1987 heat rate as the bench mark for limiting the use of unit 
    efficiency improvements. This is because annual generation was more 
    likely to vary during 1985-1987 than was a unit's annual heat rate 
    and the use of the 1987 heat rate, which captures any efficiency 
    improvement measures instituted before 1988, is less burdensome for 
    utilities and EPA to determine than the average 1985-1987 heat rate.
    ---------------------------------------------------------------------------
    
    V. Part 73: Allowances
    
    A. Allowance Tables
    
        In the proposal, EPA proposed a number of changes in unadjusted 
    allowances and in the units and allowance figures listed in Tables 2 
    and 3 of Sec. 73.10, reflecting those allowance changes. For purposes 
    of the proposal, EPA was able to list the changes in the rule without 
    reprinting Tables 2 and 3. However, consistent with the requirements of 
    the Federal Register concerning finalization of multiple changes to 
    regulatory tables and in the interest of facilitating public 
    understanding of the final changes, EPA concludes that the changes 
    should be finalized through republication of information in the tables. 
    Further, section 403(a) of the Act requires the Administrator to issue 
    prior to June 1, 1998 a revision of the final allowance allocations 
    primarily to account for allocations for repowered units under section 
    409. That revision will necessitate recalculation of all units' 
    allowance allocations and so must also be implemented through 
    republication of information in Tables 2 and 3. In order to avoid the 
    confusion likely to result from, and the large expense associated with, 
    multiple republications of information in the tables, EPA has decided 
    not to finalize at this time the allowance revisions in the December 
    27, 1996 rule. Instead, EPA intends to propose in the near future the 
    revisions associated with the June 1, 1998 allocations and to 
    coordinate finalization of both the allowance revisions in the December 
    27, 1996 proposal and that future proposal.
        The only exception to this approach is the allowance changes for 
    Central Louisiana Electric Company's Rodemacher unit 2. In the December 
    27, 1996 proposal, the allowances for Rodemacher unit 2 were changed to 
    20,774 unadjusted allowances. Under a settlement of litigation 
    concerning Rodemacher unit 2's allowance allocation, the Administrator 
    agreed to sign a final rule adopting the revision to the unit's 
    allowances by October 1997. Consistent with that settlement, the 
    proposed unadjusted allowances for Rodemacher unit 2 are adopted in 
    today's rule. This single change can be made without republishing the 
    allowance tables.
    
    B. Small Diesel Refinery Provisions
    
        The proposal made certain revisions to the provisions to small 
    refinery allowance allocations. No comment was received, and the 
    revisions are adopted in today's rule.
    
    VI. Part 75: Monitoring of Units Burning Digester or Landfill Gas
    
        In the proposal, EPA requested comment on monitoring requirements 
    for units burning digester or landfill gas. No comments were received. 
    EPA intends to consider this matter in future proceedings.
    
    VII. Part 77: Excess Emissions
    
        The proposal made changes to part 77 concerning immediate deduction 
    of allowances to offset excess emissions, the deadline for paying 
    excess emissions penalties, and excess NOX emissions under a 
    NOX averaging plan. The changes received no comment or only 
    favorable comment and are adopted in the final rule.
    
    VIII. Part 78: Administrative Appeals
    
        The proposal made changes to part 78 to clarify that an 
    administrative appeal is a prerequisite for judicial review of 
    decisions of the Administrator under the Acid Rain Program and to 
    ensure that the requirement for exhaustion of administrative remedies 
    is consistent with the Supreme Court's decision in Darby v. Cisneros, 
    509 U.S. 137 (1993). On September 24, 1993, the Agency originally 
    proposed to add language stating explicitly that administrative appeal 
    is a prerequisite for judicial review. 58 FR 50088, 50104 (1993). 
    Certain commenters stated, in response to the September 24, 1993 
    proposal, that, in light of the alleged potential for ``disruptive 
    effects'' resulting from an administrative exhaustion requirement, the 
    Agency should solicit additional comment on the effect of Darby on part 
    78. EPA therefore did not finalize the September 24, 1993 proposal. 
    Instead, EPA provided further opportunity for comment by publishing the 
    December 27, 1996 proposal, which included both the changes explicitly 
    requiring exhaustion of administrative remedies and some additional 
    changes to conform with Darby. In its comments on the December 27, 1996 
    proposed rule, the same commenters submitted further comments. In their 
    second set of comments, the commenters failed to go beyond their 
    generalized claim of ``disruptive effects''. Rather than providing any 
    specific claims or examples of when administrative appeal of a 
    particular type of Administrator's decision would be ``disruptive'' to 
    the Acid Rain Program or to affected sources' compliance efforts, the 
    commenters simply expressed general concern that EPA ``failed to 
    consider'' unspecified ``disruptive'' effects.
        In the September 24, 1993 and December 27, 1996 proposals, EPA set 
    forth both the basis for requiring exhaustion of administrative 
    remedies and provisions addressing concerns over delay pending 
    completion of administrative review. Requiring exhaustion of 
    administrative remedies promotes efficient use of administrative and 
    judicial resources in that it ``allows the Agency to review * * * 
    decisions for correctness before having to defend (them) * * * in 
    Federal court.'' 58 FR 50104 (quoting the original proposed appeals 
    procedures at 56 FR 63002, 63033 (December 3, 1991)). Decisions that a 
    petitioner shows are erroneous can be reversed or corrected without 
    resource-intensive litigation before the federal courts and decisions 
    that a petitioner shows are insufficiently explained can be reexamined 
    and either reversed or better explained. The overall effect is to 
    increase the likelihood of sound decision-making and reduce the need 
    for recourse to the courts.17
    ---------------------------------------------------------------------------
    
        \17\ EPA maintains that, contrary to commenters' assertion, the 
    provision in section 307(b)(1) of the Clean Air Act on motions for 
    reconsideration is irrelevant to the question of administrative 
    appeals and is not properly interpreted as evidencing ``hostility'' 
    to the exhaustion requirement involved here. Section 307(b)(1) 
    involves judicial appeals and the effect of agency reconsideration 
    of a final action on such appeals. To the extent section 307(b)(1) 
    addresses reconsideration of a final rule, the section is irrelevant 
    to this case, which concerns administrative appeals of individual, 
    adjudicative decisions. To the extent the section addresses 
    reconsideration of an adjudicative decision, the section is still 
    irrelevant here. Reconsideration provides a second opportunity for 
    agency review of an adjudicative decision, for which an opportunity 
    for administrative review was already provided. In contrast, the 
    issue here is whether there should be an initial opportunity for EPA 
    to review its decisions on Acid Rain matters before the decisions 
    may be appealed to the courts.
    
    ---------------------------------------------------------------------------
    
    [[Page 55472]]
    
        Further, while nothing in the record indicates that delay pending 
    administrative appeal of Acid Rain Program decisions (during which 
    appeal the decisions will not be operative) will likely have 
    ``significant, adverse consequences'', the December 27, 1993 proposal 
    took reasonable account of the general possibility of such consequences 
    pending appeal.18 61 FR 68365. Despite two opportunities to 
    provide information on the alleged, potential, adverse effect of the 
    exhaustion requirement, the commenters originally objecting to the 
    requirement were apparently unable to identify any specific 
    circumstances in the Acid Rain Program under which significant, adverse 
    consequences would result from the requirement, much less provide any 
    information on the likelihood of such circumstances arising. No such 
    circumstances have been identified to EPA, and EPA is not aware of any, 
    particularly in light of the ability of the Agency, under the proposal 
    and today's rule, to expedite administrative appeals. EPA therefore 
    rejects the commenters' claim concerning ``disruptive effects'' of the 
    exhaustion requirement as speculative and unsupported.
    ---------------------------------------------------------------------------
    
        \18\ EPA did not ``acknowledge'' that there would be cases of 
    ``significant, adverse consequences'' due to delay pending appeal or 
    that any such cases would be likely to occur. Instead, EPA provided 
    procedures that could address such cases (regardless of their 
    likelihood) if they arose.
    ---------------------------------------------------------------------------
    
        Moreover, the Agency's general approach under the regulatory 
    statutes that it administers is to require exhaustion of administrative 
    remedies prior to judicial review. See, e.g., 40 CFR 71.11(l)(4) 
    (administrative appeal of final permit decision under title V of Clean 
    Air Act); 40 CFR 124.19(f)(1) (administrative appeal of final permit 
    decision under the Solid Waste Disposal Act as amended by the Resource 
    Conservation and Recovery Act (RCRA), Prevention of Significant 
    Deterioration (PSD) program in the Clean Air Act, or Underground 
    Injection Control (UCI) program in the Safe Drinking Water Act); and 40 
    CFR 124.60(g) (administrative appeal of final permit decision under 
    National Pollutant Discharge Elimination System (NPDES)). Today's rule 
    is consistent with that general approach.
        Nevertheless, the Agency crafted the proposed rule for Acid Rain 
    Program appeals to provide for flexibility to minimize delay, 
    particularly if future cases arise where delay will have a significant, 
    adverse effect. Specifically, the proposal revised the existing rule to 
    allow the Administrator, the Environmental Appeals Board, or the 
    Presiding Officer (as appropriate) to set different, reasonable time 
    periods (which could be shorter or longer than in the existing rule) 
    for administrative-appeal-related filing by parties. For example, the 
    30-day period within which motions to intervene in part 78 appeals may 
    be filed was changed to allow a different period to be set. As 
    explained in the proposal, this approach gives the Agency ``the ability 
    to accelerate the appeals proceeding where delay due to the pending 
    appeal will have significant, adverse consequences.'' 61 FR 68365. The 
    commenters argued that the Agency might not always ``share an affected 
    source's interest in avoiding'' such adverse consequences. However, the 
    Agency's approach of allowing adjustment of the time periods gives the 
    Agency the authority to accommodate the need for expeditious 
    administrative appeal and gives the affected source the opportunity to 
    show that expedition is necessary. Particularly in cases where such a 
    showing is made, the Agency intends to make reasonable efforts to 
    minimize the delay caused by the appeal. The Agency maintains that this 
    approach reasonably balances, on one hand, the important role of the 
    exhaustion requirement and, on the other, the commenter's generalized 
    concern that appeals not cause undue delay.
        The commenters failed to recommend any other approach but merely 
    stated that the Agency had not considered limiting the applicability of 
    the exhaustion requirement, foregoing the exhaustion requirement, or 
    setting tighter time limits on procedural steps. However, in explaining 
    the need for the exhaustion requirement (see 56 FR 63033, 58 FR 50104, 
    and 61 FR 68365), the Agency rejected the notion of limiting or 
    foregoing the requirement. Further, recognizing that the major purpose 
    of providing flexibility in the time periods for filings is to expedite 
    administrative appeals, EPA is modifying the proposal to provide that, 
    with a few exceptions discussed below, the time periods involved may be 
    shortened, but not lengthened.
        One of the more important exceptions to that approach is the period 
    for filing of administrative appeals.19 Commenters raised 
    concern that an Administrator's decision under the Acid Rain Program 
    would remain ``in limbo'' during a period of uncertain duration for the 
    filing of an administrative appeal. Today's rule reduces the standard 
    period for appeal to 30 days from issuance of the Administrator's 
    decision and establishes that as a fixed period that cannot be changed 
    on a case-by-case basis. The Agency is concerned that a period shorter 
    than 30 days would not provide enough time for preparation of a 
    petition that fully addresses the issues on appeal, as required under 
    Sec. 78.3(c). See, e.g., 40 CFR 78.3(c)(1) and (3) (requiring a list of 
    material issues and a clear and concise brief supporting the petition). 
    This standard appeal period is consistent with the 30-day time period 
    for administrative appeal of other actions of the Administrator under 
    the Clean Air Act and other statutes administered by EPA. See, e.g., 40 
    CFR 71.11(l)(1) (administrative appeal of final permit decision under 
    title V); 40 CFR 124.19(a) (administrative appeal of final permit 
    decision under RCRA, PSD program, or UIC program); and 40 CFR 
    124.91(a)(1) (administrative appeal of final permit decision under 
    NPDES). The reduced time period for filing appeals reduces the period 
    of uncertainty on the status of the decision while still providing a 
    reasonable opportunity for administrative appeal.20
    ---------------------------------------------------------------------------
    
        \19\ A minor exception under today's rule is the period for 
    curing defects in filings, which remains as 7 days subject to 
    shortening or lengthening at the discretion of the Environmental 
    Appeals Board or the Presiding Officer. This will minimize the 
    likelihood of a filing being permanently excluded for purely 
    technical reasons. The Agency is confident that flexibility 
    concerning this limited type of procedural deadline can be 
    implemented in a way that will not result in unnecessary delay of 
    proceedings.
        \20\ For similar reasons, the period for appealing a proposed 
    decision of a Presiding Officer to the Environmental Appeals Board 
    is fixed at 30 days under Sec. 78.20(a).
    ---------------------------------------------------------------------------
    
        From the time a decision is issued until the expiration of the 
    appeal period, there is necessarily some uncertainty about the status 
    of the decision: the parties will not know for certain whether the 
    decision will be final until the expiration of the appeal period. 
    However, this uncertainty is tempered by the fact, admitted by the 
    commenters, that the vast majority of decisions under the Acid Rain 
    Program have not been, and probably will not be, appealed. Further, the 
    limitations on the presenting of new evidence and on the raising of new 
    issues during an administrative appeal of a decision for which there 
    was an opportunity to comment will encourage parties interested in a 
    decision to submit comments. As a result, parties' positions will 
    probably be known when the decision is issued and the likelihood of 
    appeal can then be evaluated.
    
    [[Page 55473]]
    
        The commenters also suggested that a decision should be considered 
    operative during the period between the date the decision is issued and 
    the expiration of the appeal period (i.e., 30 days under today's rule) 
    unless and until a petition for administrative appeal is filed with the 
    Environmental Appeals Board. Prior to today's rule revisions, part 78 
    provided that a decision was operative from the date of issuance and 
    throughout the administrative appeal period, except to the extent the 
    decision was stayed by the Environmental Appeals Board or the Presiding 
    Officer designated by the Board. 40 CFR 78.7(a). While today's rule 
    makes a decision inoperative once a timely petition for administrative 
    appeal is filed, the status of the decision prior to appeal or the 
    running of the period for filing an appeal is unchanged. The decision 
    itself (e.g., the approval or denial of an Acid Rain permit or permit 
    revision or of a petition under part 75) may specify the date on which 
    the decision is effective. Unless the decision itself specifies an 
    effective date that is different than the date on which the decision is 
    actually issued, the decision is operative on the issuance date unless 
    and until the filing of a timely petition for administrative appeal in 
    accordance with part 78. For example, with regard to a decision 
    concerning the transfer of allowances to or from an Allowance Tracking 
    System Account, the requirement in the existing rule that the 
    Administrator implement, within 5 business days of receipt, an 
    allowance transfer request that he or she determines to be properly 
    submitted (40 CFR 73.52 and 73.53) is unchanged in the December 27, 
    1996 proposal and today's rule. In principle, if the transfer were 
    appealed under part 78, the Administrator could take action to render 
    the transfer inoperative pending appeal. However, appeal in such 
    circumstances is highly unlikely since an allowance transfer must be 
    authorized by the designated representative of the party transferring 
    the allowances. See 42 U.S.C. 7651b(b).
        For the reasons discussed here and in the September 24, 1993 and 
    December 27, 1996 proposals, the December 27, 1996 revisions are 
    adopted as modified above.
    
    IX. Administrative Requirements
    
    A. Executive Order 12866
    
        Under Executive Order 12866, 58 FR 51735 (October 4, 1993), the 
    Administrator must determine whether the regulatory action is 
    ``significant'' and therefore subject to Office of Management and 
    Budget (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.
        Pursuant to the terms of Executive Order 12866, it has been 
    determined that this final rule is a ``significant regulatory action'' 
    because the rule seems to raise novel legal or policy issues. As such, 
    this action was submitted to OMB for review. Any written comments from 
    OMB to EPA, any written EPA response to those comments, and any changes 
    made in response to OMB suggestions or recommendations are included in 
    the docket. The docket is available for public inspection at the EPA's 
    Air Docket Section, which is listed in the ADDRESSES section of this 
    preamble.
    
    B. Unfunded Mandates Act
    
        Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Pub. 
    L. 104-4, establishes requirements for federal agencies to assess the 
    effects of their regulatory actions on State, local, and tribal 
    governments and the private sector. Under section 202 of the UMRA, EPA 
    generally must prepare a written statement, including a cost-benefit 
    analysis, before promulgating a proposed or final rule that includes a 
    federal mandate that may result in expenditure by State, local, and 
    tribal governments, in aggregate, or by the private sector, of $100 
    million or more in any one year. Section 205 generally requires that, 
    before promulgating a rule for which a written statement must be 
    prepared, EPA identify and consider a reasonable number of regulatory 
    alternatives and adopt the least costly, most cost-effective, or least 
    burdensome alternative that achieves the objectives of the rule. The 
    provisions of section 205 do not apply when they are inconsistent with 
    applicable law. Moreover, section 205 allows EPA to adopt an 
    alternative other than the least costly, most cost-effective, or least 
    burdensome alternative if the Administrator explains why that 
    alternative was not adopted. Finally, section 203 requires that, before 
    establishing any regulatory requirements that may significantly or 
    uniquely affect small governments, EPA must have developed a small 
    government agency plan. The plan must provide for notifying any 
    potentially affected small govenments, enabling officials of affected 
    small governments to have meaningful and timely input in the 
    development of EPA regulatory proposals with significant federal 
    intergovernmental mandates, and informing, educating, and advising 
    small governments on compliance with the regulatory requirements.
        Because this final rule is estimated to result in the expenditure 
    by State, local, and tribal governments or the private sector of less 
    than $100 million in any one year, the Agency has not prepared a 
    budgetary impact statement or specifically addressed the selection of 
    the least costly, most cost-effective, or least burdensome alternative. 
    Because small governments will not be significantly or uniquely 
    affected by this rule, the Agency is not required to develop a plan 
    with regard to small governments.
        For the reasons discussed in detail here and in the proposal (61 FR 
    68340), the final rule has the net effect of reducing the burden of 
    parts 72, 77, and 78 of the Acid Rain regulations on regulated entities 
    (including both investor-owned and municipal utilities) and on State 
    permitting authorities (which may include State, local, and tribal 
    governments). For example, the final rule reduces the burden of 
    obtaining or providing new units and retired units exemptions from the 
    Acid Rain Program and of issuing Acid Rain permits.
        The final revisions to part 73 also do not have a significant, 
    adverse effect on regulated entities (including small entities) and 
    have no effect on State permitting authorities. The final rule 
    increases the annual unadjusted basic allowances for one unit by 2,312 
    allowances. In a future action, the Agency will act on the other 
    allowance revisions in the proposal. Sections 403(a) and 405(a)(3) of 
    the Act set a nationwide cap on annual allowance allocations. Because 
    of the requirement to adhere to the cap, the increase of allowances 
    under this final rule (if not offset by the other allowance revisions 
    when they are finalized) would eventually necessitate an equal decrease 
    in the total annual allocations of all other units. The small decrease 
    (i.e., 2,312 allowances out of an annual
    
    [[Page 55474]]
    
    nationwide cap of about 8.95 million allowances or about 0.026 percent) 
    would be spread among all other units, and so the effect on any one 
    unit would be insignificant. Moreover, EPA is not, in today's rule, 
    adjusting the allocations of the other units to account for this small 
    allowance increase.
    
    C. Paperwork Reduction Act
    
        OMB has approved the information collection requirements contained 
    in this final rule under the provisions of the Paperwork Reduction Act, 
    44 U.S.C. 3501, et seq., and has assigned OMB control number 2060-0258.
        The only additional information required by this collection of 
    information is data concerning industrial utility-units that exercise 
    the option of applying for the industrial utility-units exemption 
    established by today's rule. If granted, the industrial utility-units 
    exemption exempts the unit from most requirements of the Acid Rain 
    Program, e.g., allowance, monitoring, and annual compliance 
    requirements. The requirements from which qualified industrial utility-
    units will be exempt are significantly more burdensome than the 
    information collection requirements for obtaining the 
    exemption.21 An industrial utility-unit seeking the 
    exemption must meet the information collection requirements, which 
    involve submission of information that is necessary, and will be used, 
    for determining whether the unit qualifies and will continue to qualify 
    for the exemption.
    ---------------------------------------------------------------------------
    
        \21\ Because the information collection burden on industrial 
    utility-units in the absence of this new exemption was not included 
    in the ICR for the existing rule, the effect of removing such burden 
    through the new exemption is not included in the ICR for today's 
    rule. Consequently, the ICR for today's rule shows an increase in 
    burden even though exempt industrial utility-units will actually 
    experience a significant net reduction in the burden imposed on them 
    by the Acid Rain Program. In addition, as discussed in this 
    preamble, today's rule includes other revisions that will reduce 
    somewhat the burden of the program on units that are not exempt. 
    Because the burden reduction for non-exempt units is small relative 
    to the total burden of the program, the reduction is not reflected 
    in the ICR for today's rule.
    ---------------------------------------------------------------------------
    
        The additional information collection increases the estimated 
    burden, as compared to the burden under the existing rule, by an 
    average of 24 hours per response for an estimated 15 one-time 
    responses. 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. EPA is amending the table in 
    40 CFR part 9 of currently approved ICR control numbers issued by OMB 
    for various regulations to list the information requirements contained 
    in this final rule.
    
    D. Regulatory Flexibility
    
        The Regulatory Flexibility Act, 5 U.S.C. 601, et seq., requires 
    federal agencies to consider potential impacts of its regulations on 
    small entities. Under 5 U.S.C. 604(a), an agency issuing a notice of 
    final rulemaking under section 553 of the Administrative Procedure Act, 
    must prepare and make available for public comment a final regulatory 
    flexibility analysis. Such an analysis is not required if the head of 
    an agency determines, under 5 U.S.C. 605(b), that the final rule will 
    not have a significant economic impact on a substantial number of small 
    entities.
        In the preamble of the January 11, 1993 rule, the Administrator 
    certified that the rule, including the provisions revised by today's 
    rule, would not have a significant, adverse impact on small entities. 
    58 FR 3649. Today's final revisions are not significant enough to 
    change the overall economic impact addressed in the January 11, 1993 
    preamble. Moreover, as discussed in this preamble, today's rule has the 
    net effect of reducing the burden of the Acid Rain regulations on 
    regulated entities, including small entities. For example, the rule 
    makes it less burdensome to obtain new units and retired units 
    exemptions from the Acid Rain Program. Further, the rule increases the 
    allowances for one unit, which increase will have an insignificant 
    effect on other units' allowance allocations.
        For the reasons discussed above, EPA has determined that it is not 
    necessary to prepare a regulatory flexibility analysis in connection 
    with this final rule. EPA has determined that this rule will not have a 
    significant, economic impact on a substantial number of small entities.
    
    E. Submission to Congress and the General Accounting Office
    
        Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
    Regulatory Enforcement Fairness Act of 1996, EPA submitted a report 
    containing this rule and other required information to the U.S. Senate, 
    the U.S. House of Representatives, and the Comptroller General of the 
    General Accounting Office prior to publication of the rule in today's 
    Federal Register. This rule is not a ``major rule'' as defined by 5 
    U.S.C. 804(2).
    
    F. Miscellaneous
    
        In accordance with section 117 of the Act, issuance of this final 
    rule was preceded by consultation with any appropriate advisory 
    committees, independent experts, and federal departments and agencies.

        7. Section 72.7 is revised to read as follows:
    
    
    Sec. 72.7  New units exemption.
    
        (a) Applicability. This section applies to any new utility unit 
    that has not previously lost an exemption under paragraph (f)(4) of 
    this section and that, in each year starting with the first year for 
    which the unit is to be exempt under this section:
        (1) Serves during the entire year (except for any period before the 
    unit commenced commercial operation) one or more generators with total 
    nameplate capacity of 25 MWe or less;
        (2) Burns fuel that does not include any coal or coal-derived fuel 
    (except coal-derived gaseous fuel with a total sulfur content no 
    greater than natural gas); and
        (3) Burns gaseous fuel with an annual average sulfur content of 
    0.05 percent or less by weight (as determined under paragraph (d) of 
    this section) and nongaseous fuel with an annual average sulfur content 
    of 0.05 percent or less by weight (as determined under paragraph (d) of 
    this section).
        (b)(1) Any new utility unit that meets the requirements of 
    paragraph (a) of this section and that is not allocated any allowances 
    under subpart B of part 73 of this chapter shall be exempt from the 
    Acid Rain Program, except for the provisions of this section, 
    Secs. 72.2 through 72.6, and Secs. 72.10 through 72.13.
        (2) The exemption under paragraph (b)(1) of this section shall be 
    effective on January 1 of the first full calendar year for which the 
    unit meets the requirements of paragraph (a) of this section. By 
    December 31 of the first year for which the unit is to be exempt under 
    this section, a statement signed by the designated representative 
    (authorized in accordance with subpart B of this part) or, if no 
    designated representative has been authorized, a certifying official of 
    each owner of the unit shall be submitted to permitting authority 
    otherwise responsible for administering a Phase II Acid Rain permit for 
    the unit. If the Administrator is not the permitting authority, a copy 
    of the statement shall be submitted to the Administrator. The 
    statement, which shall be in a format prescribed by the Administrator, 
    shall identify the unit, state the nameplate capacity of each generator 
    served by the unit and the fuels currently burned or expected to be 
    burned by the unit and their sulfur content by weight, and state that 
    the owners and operators of the unit will comply with paragraph (f) of 
    this section.
        (3) After receipt of the statement under paragraph (b)(2) of this 
    section, the permitting authority shall amend under Sec. 72.83 the 
    operating permit covering the source at which the unit is located, if 
    the source has such a permit, to add the provisions and requirements of 
    the exemption under paragraphs (a), (b)(1), (d), and (f) of this 
    section.
        (c)(1) Any new utility unit that meets the requirements of 
    paragraph (a) of this section and that is allocated one or more 
    allowances under subpart B of part 73 of this chapter shall be exempt 
    from the Acid Rain Program, except for the provisions of this section, 
    Secs. 72.2 through 72.6, and Secs. 72.10 through 72.13, if each of the 
    following requirements are met:
        (i) The designated representative (authorized in accordance with 
    subpart B of this part) or, if no designated representative has been 
    authorized, a certifying official of each owner of the unit submits to 
    the permitting authority otherwise responsible for administering a 
    Phase II Acid Rain permit for the unit a statement (in a format 
    prescribed by the Administrator) that:
        (A) Identifies the unit and states the nameplate capacity of each 
    generator served by the unit and the fuels currently burned or expected 
    to be burned by the unit and their sulfur content by weight;
        (B) States that the owners and operators of the unit will comply 
    with paragraph (f) of this section;
        (C) Surrenders allowances equal in number to, and with the same or 
    earlier compliance use date as, all of those allocated to the unit 
    under subpart B of part 73 of this chapter for the first year that the 
    unit is to be exempt under this section and for each subsequent year; 
    and
        (D) Surrenders any proceeds for allowances under paragraph 
    (c)(1)(i)(C) or this section withheld from the unit under Sec. 73.10 of 
    this chapter. If the Administrator is not the permitting authority, a 
    copy of the statement shall be submitted to the Administrator.
        (ii) The Administrator deducts from the unit's Allowance Tracking 
    System account allowances under paragraph (c)(1)(i)(C) of this section 
    and receives proceeds under paragraph (c)(1)(i)(D) of this section. 
    Within 5 business days of receiving a statement in accordance with 
    paragraph (c)(1)(i) of this section, the Administrator shall either 
    deduct the allowances under paragraph (c)(1)(i)(C) of this section or 
    notify the owners and operators that there are insufficient allowances 
    to make such deductions. Upon completion of such deductions and receipt 
    of such proceeds, the Administrator will close the unit's Allowance 
    Tracking System account and notify the designated representative (or 
    certifying official) and, if the Administrator is not the permitting 
    authority otherwise responsible for administering a Phase II Acid Rain 
    permit for the unit, the permitting authority.
        (2) The exemption under paragraph (c)(1) of this section shall be 
    effective on January 1 of the first full calendar year for which the 
    requirements of paragraphs (a) and (c)(1) of this section are met. 
    After notification by the Administrator under the third sentence of 
    paragraph (c)(1)(ii) of this section, the permitting authority shall 
    amend under Sec. 72.83 the operating permit covering the source at 
    which the unit is located, if the source has such a permit, to add the 
    provisions and requirements of the exemption under paragraphs (a), 
    (c)(1), (d), and (f) of this section.
        (d) Compliance with the requirement that fuel burned during the 
    year have an annual average sulfur content of 0.05 percent by weight or 
    less shall be determined as follows using a method of determining 
    sulfur content that provides information with reasonable precision, 
    reliability, accessibility, and timeliness:
        (1) For gaseous fuel burned during the year, if natural gas is the 
    only gaseous fuel burned, the requirement is assumed to be met;
        (2) For gaseous fuel burned during the year where other gas in 
    addition to or besides natural gas is burned, the requirement is met if 
    the annual average sulfur content is equal to or less than 0.05 percent 
    by weight. The annual average sulfur content, as a percentage by 
    weight, for the gaseous fuel burned shall be calculated as follows:
    [GRAPHIC] [TIFF OMITTED] TR24OC97.001
    
    Where:
    
    %Sannual=annual average sulfur content of the fuel burned 
    during the year by the unit, as a percentage by weight;
    %Sn=sulfur content of the nth sample of the fuel delivered 
    during the year to the unit, as a percentage by weight;
    Vn=volume of the fuel in a delivery during the year to the 
    unit of which the nth sample is taken, in standard cubic feet; or, for 
    fuel delivered during the year to the unit continuously by pipeline, 
    volume of the fuel delivered starting from when the nth sample of such 
    fuel is taken until the next sample of such fuel is taken, in standard 
    cubic feet;
    dn=density of the nth sample of the fuel delivered during 
    the year to the
    
    [[Page 55477]]
    
    unit, in lb per standard cubic foot; and
    n=each sample taken of the fuel delivered during the year to the unit, 
    taken at least once for each delivery; or, for fuel that is delivered 
    during the year to the unit continuously by pipeline, at least once 
    each quarter during which the fuel is delivered.
        (3) For nongaseous fuel burned during the year, the requirement is 
    met if the annual average sulfur content is equal to or less than 0.05 
    percent by weight. The annual average sulfur content, as a percentage 
    by weight, shall be calculated using the equation in paragraph (d)(2) 
    of this section. In lieu of the factor, volume times density 
    (Vn dn), in the equation, the factor, mass 
    (Mn), may be used, where Mn is: mass of the 
    nongaseous fuel in a delivery during the year to the unit of which the 
    nth sample is taken, in lb; or, for fuel delivered during the year to 
    the unit continuously by pipeline, mass of the nongaseous fuel 
    delivered starting from when the nth sample of such fuel is taken until 
    the next sample of such fuel is taken, in lb.
        (e)(1) A utility unit that was issued a written exemption under 
    this section and that meets the requirements of paragraph (a) of this

    chapter, the designated representative (authorized in accordance with 
    subpart B of this part) or, if no designated representative has been 
    authorized, a certifying official of each owner of the unit shall 
    submit to the permitting authority that issued the written exemption a 
    statement (in a format prescribed by the Administrator) meeting the 
    requirements of paragraph (c)(1)(i)(C) and (D) of this section. The 
    statement shall be submitted by June 31, 1998 and, if the Administrator

        (A) The first date on which there is an owner or operator of the 
    unit, division or subsidiary or affiliate or parent company of an owner 
    or operator of the unit, or combination thereof, whose principal 
    business is the sale, transmission, or distribution of electricity or 
    that is a public utility under the jurisdiction of a State or local 
    utility regulatory authority.
        (B) If any generator served by the unit actually produces any

    [[Page 55480]]
    
    related power purchase agreement under paragraph (a)(2) of this section 
    or a successor agreement under paragraph (d)(4)(ii) of this section 
    where such sale is not required under that interconnection agreement or 
    related power purchase agreement or successor agreement or where such 
    sale will result in total sales for a calendar year exceeding 10 
    percent of the nameplate capacity of that generator times 8,769 hours 
    per year, then the day after the date on which such sale is made.
        (D) If any generator served by the unit actually produces any 
    electricity for sale to the person specified as the purchaser in the 
    interconnection agreement or related power purchase agreement under 
    paragraph (a)(2) of this section or a successor agreement under 
    paragraph (d)(4)(ii) of this section where such sale results in total 
    sales for a calendar year exceeding 10 percent of the actual electric

    agreement under paragraph (a)(2) of this section expires or is 
    terminated, no successor agreement under paragraph (d)(4)(ii) of this 
    section is in effect, and any generator served by the unit actually 
    produces any electricity for sale, then the day after the date on which 
    such electricity is sold.
        (ii) A ``successor agreement'' is an agreement that:
        (A) Modifies, replaces or supersedes the interconnection agreement 
    or related power purchase agreement under paragraph (a)(2) of this 
    section;
        (B) Is between the owners and operators of the unit and a person

    for sale under the interconnection agreement or related power purchase 
    agreement (to the extent they are still in effect) and the successor 
    agreement shall not exceed the total amount of electricity that such 
    generator was required to produce for sale under the interconnection 
    agreement or related power purchase agreement under paragraph (a)(2) of 
    this section.
        (iii) Notwithstanding Sec. 72.30(b) and (c), the designated

        (a) Scope. This subpart and parts 74, 76, and 78 of this chapter 
    contain the procedures for federal issuance of Acid Rain permits for 
    Phase I of the Acid Rain Program and Phase II for sources for which the 
    Administrator is the permitting authority under Sec. 72.74.
        (1) Notwithstanding the provisions of part 71 of this chapter, the 
    provisions of subparts C, D, E, F, and H of this part and of parts 74, 
    76, and 78 of this chapter shall govern the following requirements for 
    Acid Rain permit applications and permits: submission, content, and 
    effect of permit applications; content and requirements of compliance 
    plans and compliance options; content of permits and permit shield; 
    procedures for determining completeness of permit applications; 
    issuance of draft permits; administrative record; public notice and 
    comment and public hearings on draft permits; response to comments on 
    draft permits; issuance and effectiveness of permits; permit revisions; 
    and administrative appeal procedures. The provisions of part 71 of this 
    chapter concerning Indian tribes, delegation of a part 71 program, 
    affected State review of draft permits, and public petitions to reopen 
    a permit for cause shall apply to Acid Rain permit applications and

    Acid Rain permits by State permitting authorities with operating permit 
    programs approved under part 70 of this chapter, except as expressly 
    provided in subpart G of this part.
        (b) Permit Decision Deadlines. Except as provided in 
    Sec. 72.74(c)(1)(i), the Administrator will issue or deny an Acid Rain 
    permit under Sec. 72.69(a) within 6 months of receipt of a complete 
    Acid Rain permit application submitted for a unit, in accordance with 
    Sec. 72.21, at the U.S. EPA Regional Office for the Region in which the 
    source is located.
        (c) Use of Direct Final Procedures. The Administrator may, in his 
    or her discretion, issue, as single document, a draft Acid Rain permit 
    in accordance with Sec. 72.62 and an Acid Rain permit in final form and 
    may provide public notice of the opportunity for public comment on the 
    draft Acid Rain permit in accordance with Sec. 72.65. The Administrator 
    may provide that, if no significant, adverse comment on the draft Acid 
    Rain permit is timely submitted, the Acid Rain permit will be deemed to 
    be issued on a specified date without further notice and, if such 
    significant, adverse comment is timely submitted, an Acid Rain permit 
    or denial of an Acid Rain permit will be issued in accordance with 
    Sec. 72.69. Any notice provided under this paragraph (c) will include a 
    description of the procedure in the prior sentence.
        25. Section 72.61 is amended by revising paragraphs (a) and

    source is located. The permit application shall be deemed to be 
    complete if the Administrator fails to
    
    [[Page 55482]]
    
    notify the designated representative to the contrary within 60 days of 
    receipt.
        (b) * * *
        (2)(i) Within a reasonable period determined by the Administrator, 
    the designated representative shall submit the information required 
    under paragraph (b)(1) of this section.
    * * * * *
        (3) Any designated representative who fails to submit any relevant 
    information or who has submitted incorrect information in a permit 
    application shall, upon becoming aware of such failure or incorrect 
    submittal, promptly submit such supplementary information or corrected 
    information to the Administrator.
        26. Section 72.65 is amended by revising paragraphs (b)(1)(ii), 
    (b)(1)(iii), and (b)(2) and by removing paragraph (b)(1)(iv) to read as

    newspaper of general circulation in the area where the source covered 
    by the Acid Rain permit application is located or in a State 
    publication designed to give general public notice. Notwithstanding the 
    prior sentence, if a draft permit requires the affected units at a 
    source to comply with Sec. 72.9(c)(1) and to meet any applicable 
    emission limitation for NOX under Secs. 76.5, 76.6, 76.7, 
    76.8, or 76.11 of this chapter and does not include for any unit a 
    compliance option under Sec. 72.44, part 74 of this chapter, or 
    Sec. 76.10 of this chapter, the Administrator may, in his or her 
    discretion, provide notice of the draft permit by Federal Register

    copy of any Acid Rain permit and the response to comments on the 
    designated representative for the source covered by the issuance or 
    denial and serve written notice of the issuance or denial on the air 
    pollution control agencies of affected States and any interested 
    person. The Administrator will also give notice in the Federal 
    Register.
    * * * * *
        28. Section 72.70 is revised to read as follows:
    
    
    Sec. 72.70  Relationship to title V operating permit program.
    
        (a) Scope. This subpart sets forth criteria for approval of State 
    operating permit programs and acceptance of State Acid Rain programs, 
    the procedure for including State Acid Rain programs in a title V 
    operating permit program, and the requirements with which State 
    permitting authorities with accepted programs shall comply, and with 
    which the Administrator will comply in the absence of an accepted State 
    program, to issue Phase II Acid Rain permits.
        (b) Relationship to operating permit program. Each State permitting 
    authority with an affected source shall act in accordance with this 
    part and parts 70, 74, 76, and 78 of this chapter for the purpose of 
    incorporating Acid Rain Program requirements into each affected 
    source's operating permit or for issuing exemptions under Sec. 72.14. 
    To the extent that this part or part 74, 76, or 78 of this chapter is 
    inconsistent with the requirements of part 70 of this chapter, this 
    part and parts 74, 76, and 78 of this chapter shall take precedence and 
    shall govern the issuance, denial, revision, reopening, renewal, and 
    appeal of the Acid Rain portion of an operating permit.
        29. Section 72.71 is revised to read as follows:
    
    
    Sec. 72.71  Acceptance of State Acid Rain programs--general.
    
        (a) Each State shall submit, to the Administrator for review and 
    acceptance, a State Acid Rain program meeting the requirements of 
    Secs. 72.72 and 72.73.
        (b) The Administrator will review each State Acid Rain program or 
    portion of a State Acid Rain program and accept, by notice in the 
    Federal Register, all or a portion of such program to the extent that 
    it meets the requirements of Secs. 72.72 and 72.73. At his or her 
    discretion, the Administrator may accept, with conditions and by notice 
    in the Federal Register, all or a portion of such program despite the 
    failure to meet requirements of Secs. 72.72 and 72.73. On the later of 
    the date of publication of such notice in the Federal Register or the 
    date on which the State operating permit program is approved under part 
    70 of this chapter, the State Acid Rain program accepted by the 
    Administrator will become a portion of the approved State operating 
    permit program. Before accepting or rejecting all or a portion of a 
    State Acid Rain Program, the Administrator will provide notice and 
    opportunity for public comment on such acceptance or rejection.
        (c)(1) Except as provided in paragraph (c)(2) of this section, the 
    Administrator will issue all Acid Rain permits for Phase I. The 
    Administrator reserves the right to delegate the remaining 
    administration and enforcement of Acid Rain permits for Phase I to 
    approved State operating permit programs.
        (2) The State permitting authority will issue an opt-in permit for 
    a combustion or process source subject to its jurisdiction if, on the 
    date on which the combustion or process source submits an opt-in permit 
    application, the State permitting authority has opt-in regulations 
    accepted under paragraph (b) of this section and an approved operating 
    permits program under part 70 of this chapter.
        30. Section 72.72 is amended by:
        a. Removing paragraphs (b)(1)(i)(C), (b)(1)(vii), (b)(1)(viii), 
    (b)(1)(xi), (b)(1)(xiii), (b)(5)(vii), (b)(7), and (b)(8);
        b. Removing the last sentence of paragraph (b)(5)(v);

    Sec. 72.72  Criteria for State operating permit program.
    
        A State operating permit program (including a State Acid Rain 
    program) shall meet the following criteria. Any aspect of a State 
    operating permits program or any implementation of a State operating 
    permit program that fails to meet these criteria shall be grounds for 
    nonacceptance or withdrawal of all or part of the Acid Rain portion of 
    an approved State operating permit program by the Administrator or for 
    disapproval or withdrawal of approval of the State operating permit 
    program by the Administrator.
    * * * * *
        (b) The State operating permit program shall require the following 
    provisions, which are adopted to the extent that this paragraph (b) is 
    incorporated by reference or is
    
    [[Page 55483]]
    
    otherwise included in the State operating permit program.
        (1) * * *

    accordance with paragraph (b)(1)(iii) of this section. The State 
    permitting authority may provide that, if no significant, adverse 
    comment on the draft Acid Rain permit is timely submitted, the proposed 
    Acid Rain permit will be deemed to be issued on a specified date 
    without further notice and, if such significant, adverse comment is 
    timely submitted, a proposed Acid Rain permit or denial of a proposed 
    Acid Rain permit will be issued in accordance with paragraph (b)(1)(iv) 
    of this section. Any notice provided under this paragraph (b)(1)(v) 
    shall include a description of the procedure in the prior sentence.

    * * * * *
        (vi) A failure of the State permitting authority to issue an Acid 
    Rain permit in accordance with Sec. 72.73(b)(1) or, with regard to 
    combustion or process sources, Sec. 74.14(b)(6) of this chapter shall 
    be ground for filing an appeal.
        (6) Industrial Utility-Units Exemption. The State permitting 
    authority shall act in accordance with Sec. 72.14 on any petition for 
    exemption from requirements of the Acid Rain Program.
        31. Section 72.73 is revised to read as follows:
    
    
    Sec. 72.73  State issuance of Phase II permits.
    
        (a) State Permit Issuance. (1) A State that is authorized to 
    administer and enforce an operating permit program under part 70 of 
    this chapter and that has a State Acid Rain program accepted by the 
    Administrator under Sec. 72.71 shall be responsible for administering 
    and enforcing Acid Rain permits effective in Phase II for all affected 
    sources:
        (i) That are located in the geographic area covered by the 
    operating permits program; and
        (ii) To the extent that the accepted State Acid Rain program is 
    applicable.
        (2) In administering and enforcing Acid Rain permits, the State 
    permitting authority shall comply with the procedures for issuance, 
    revision, renewal, and appeal of Acid Rain permits under this subpart.
        (b) Permit Issuance Deadline. (1) A State, to the extent that it is 
    responsible under paragraph (a) of this section as of December 31, 1997 
    (or such later date as the Administrator may establish) for 
    administering and enforcing Acid Rain permits, shall:
        (i) On or before December 31, 1997, issue an Acid Rain permit for 
    Phase II covering the affected units (other than opt-in sources) at 
    each source in the geographic area for which the program is approved; 
    provided that the designated representative of the source submitted a 
    timely and complete Acid Rain permit application in accordance with 
    Sec. 72.21.
        (ii) On or before January 1, 1999, for each unit subject to an Acid 
    Rain NOX emissions limitation, amend the Acid Rain permit 
    under Sec. 72.83 and add any NOX early election plan that 
    was approved by the Administrator under Sec. 76.8 of this chapter and 
    has not been terminated and reopen the Acid Rain permit and add any 
    other Acid Rain Program nitrogen oxides requirements; provided that the 
    designated representative of the affected source submitted a timely and 
    complete Acid Rain permit application for nitrogen oxides in accordance 
    with Sec. 72.21.
        (2) Each Acid Rain permit issued in accordance with this section 
    shall have a term of 5 years commencing on its effective date; provided 
    that, at the discretion of the permitting authority, the first Acid 
    Rain permit for Phase II issued to a source may have a term of less 
    than 5 years where necessary to coordinate the term of such permit with 
    the term of an operating permit to be issued to the source under a 
    State operating permit program. Each Acid Rain permit issued in 
    accordance with paragraph (b)(1) of this section shall take effect by 
    the later of January 1, 2000, or, where the permit governs a unit under 
    Sec. 72.6(a)(3) of this part, the deadline for monitor certification 
    under part 75 of this chapter.
        32. Section 72.74 is revised to read as follows:
    
    
    Sec. 72.74  Federal issuance of Phase II permits.
    
        (a)(1) The Administrator will be responsible for administering and 
    enforcing Acid Rain permits for Phase II for any affected sources to 
    the extent that a State permitting authority is not responsible, as of 
    January 1, 1997 or such later date as the Administrator may establish, 
    for administering and enforcing Acid Rain permits for such sources 
    under Sec. 72.73(a).
        (2) After and to the extent the State permitting authority becomes 
    responsible for administering and enforcing Acid Rain permits under 
    Sec. 72.73(a), the Administrator will
    
    [[Page 55484]]
    
    suspend federal administration of Acid Rain permits for Phase II for 
    sources and units to the extent that they are subject to the accepted 
    State Acid Rain program, except as provided in paragraph (b)(4) of this 
    section.
        (b)(1) The Administrator will administer and enforce Acid Rain 
    permits effective in Phase II for sources and units during any period 
    that the Administrator is administering and enforcing an operating 
    permit program under part 71 of this chapter for the geographic area in 
    which the sources and units are located.
        (2) The Administrator will administer and enforce Acid Rain permits 
    effective in Phase II for sources and units otherwise subject to a 
    State Acid Rain program under Sec. 72.73(a) if:
        (i) The Administrator determines that the State permitting 
    authority is not adequately administering or enforcing all or a portion 
    of the State Acid Rain program, notifies the State permitting authority 
    of such determination and the reasons therefore, and publishes such 
    notice in the Federal Register;
        (ii) The State permitting authority fails either to correct the 
    deficiencies within a reasonable period (established by the 
    Administrator in the notice under paragraph (b)(2)(i) of this section) 
    after issuance of the notice or to take significant action to assure 
    adequate administration and enforcement of the program within a 
    reasonable period (established by the Administrator in the notice) 
    after issuance of the notice; and
        (iii) The Administrator publishes in the Federal Register a notice 
    that he or she will administer and enforce Acid Rain permits effective 
    in Phase II for sources and units subject to the State Acid Rain 
    program or a portion of the program. The effective date of such notice 
    shall be a reasonable period (established by the Administrator in the 
    notice) after the issuance of the notice.
        (3) When the Administrator administers and enforces Acid Rain 
    permits under paragraph (b)(1) or (b)(2) of this section, the 
    Administrator will administer and enforce each Acid Rain permit issued 
    under the State Acid Rain program or portion of the program until, and 
    except to the extent that, the permit is replaced by a permit issued 
    under this section. After the later of the date for publication of a 
    notice in the Federal Register that the State operating permit program 
    is currently approved by the Administrator or that the State Acid Rain 
    program or portion of the program is currently accepted by the 
    Administrator, the Administrator will suspend federal administration of 
    Acid Rain permits effective in Phase II for sources and units to the 
    extent that they are subject to the State Acid Rain program or portion 
    of the program, except as provided in paragraph (b)(4) of this section.
        (4) After the State permitting authority becomes responsible for 
    administering and enforcing Acid Rain permits effective in Phase II 
    under Sec. 72.73(a), the Administrator will continue to administer and 
    enforce each Acid Rain permit issued under paragraph (a)(1), (b)(1), or 
    (b)(2) of this section until, and except to the extent that, the permit 
    is replaced by a permit issued under the State Acid Rain program. The 
    State permitting authority may replace an Acid Rain permit issued under 
    paragraph (a)(1), (b)(1), or (b)(2) of this section by issuing a permit 
    under the State Acid Rain program by the expiration of the permit under 
    paragraph (a)(1), (b)(1), or (b)(2) of this section. The Administrator 
    may retain jurisdiction over the Acid Rain permits issued under 
    paragraph (a)(1), (b)(1), or (b)(2) of this section for which the 
    administrative or judicial review process is not complete and will 
    address such retention of jurisdiction in a notice in the Federal 
    Register.
        (c) Permit Issuance Deadline. (1)(i) On or before January 1, 1998, 
    the Administrator will issue an Acid Rain permit for Phase II setting 
    forth the Acid Rain Program sulfur dioxide requirements for each 
    affected unit (other than opt-in sources) at a source not under the 
    jurisdiction of a State permitting authority that is responsible, as of 
    January 1, 1997 (or such later date as the Administrator may 
    establish), under Sec. 72.73(a) of this section for administering and 
    enforcing Acid Rain permits with such requirements; provided that the 
    designated representative for the source submitted a timely and 
    complete Acid Rain permit application in accordance with Sec. 72.21. 
    The failure by the Administrator to issue a permit in accordance with 
    this paragraph shall be grounds for the filing of an appeal under part 
    78 of this chapter.
        (ii) Each Acid Rain permit issued in accordance with this section 
    shall have a term of 5 years commencing on its effective date. Each 
    Acid Rain permit issued in accordance with paragraph (c)(1)(i) of this 
    section shall take effect by the later of January 1, 2000 or, where a 
    permit governs a unit under Sec. 72.6(a)(3), the deadline for monitor 
    certification under part 75 of this chapter.
        (2) Nitrogen Oxides. Not later than 6 months following submission 
    by the designated representative of an Acid Rain permit application for 
    nitrogen oxides, the Administrator will amend under Sec. 72.83 the Acid 
    Rain permit and add any NOX early election plan that was 
    approved under Sec. 76.8 of this chapter and has not been terminated 
    and reopen the Acid Rain permit for Phase II and add any other Acid 
    Rain Program nitrogen oxides requirements for each affected source not 
    under the jurisdiction of a State permitting authority that is 
    responsible, as of January 1, 1997 (or such later date as the 
    Administrator may establish), under Sec. 72.73(a) for issuing Acid Rain 
    permits with such requirements; provided that the designated 
    representative for the source submitted a timely and complete Acid Rain 
    permit application for nitrogen oxides in accordance with Sec. 72.21.
        (d) Permit Issuance. (1) The Administrator may utilize any or all 
    of the provisions of subparts E and F of this part to administer Acid 
    Rain permits as authorized under this section or may adopt by 
    rulemaking portions of a State Acid Rain program in substitution of or 
    in addition to provisions of subparts E and F of this part to 
    administer such permits. The provisions of Acid Rain permits for Phase 
    I or Phase II issued by the Administrator shall not be applicable 
    requirements under part 70 of this chapter.
        (2) The Administrator may delegate all or part of his or her 
    responsibility, under this section, for administering and enforcing 
    Phase II Acid Rain permits or opt-in permits to a State. Such 
    delegation will be made consistent with the requirements of this part 
    and the provisions governing delegation of a part 71 program under part 
    71 of this chapter.

    subaccount for the calendar year in accordance with Secs. 72.92(a) and 
    (c) and 73.35(b) of this chapter:
        (A) The designated representative shall recalculate the unit's 
    adjusted utilization in accordance with paragraph (a) of this section, 
    replacing the amounts for reduction from energy conservation and 
    reduction from improved unit efficiency by the amount for verified heat 
    input reduction. ``Verified heat input reduction'' is the total of the 
    amounts of verified reduction in the unit's heat input (in mmBtu) from 
    energy conservation and improved unit efficiency measures included in 
    the confirmation report.
        (B) After recalculating the adjusted utilization under paragraph 
    (b)(5)(ii)(A) of this section for all Phase I units that are in the 
    unit's dispatch system and to which paragraph (b)(5) of this section is 
    applicable, the designated representative shall calculate the number of 
    allowances to be surrendered in accordance with Sec. 72.92(c)(2) using 
    the recalculated adjusted utilizations of such Phase I units.
        (C) The allowances to be deducted under paragraph (b)(5) of this 
    section shall equal the amount under paragraph (b)(5)(ii)(B) of this 
    section, provided that if the amount calculated under this paragraph 
    (b)(5)(ii)(C) is equal to or less than zero, then the amount of 
    allowances to be deducted is zero.
        (6) The Administrator will determine the amount of allowances that 
    would have been included in the unit's compliance subaccount and the 
    amount of excess emissions of sulfur dioxide that would have resulted 
    if the deductions made under Sec. 73.35(b) of this chapter had been 
    based on the verified, rather than the estimated, reduction in the 
    unit's heat input from energy conservation and improved unit efficiency 
    measures.
        (7) The Administrator will determine whether the amount of excess 
    emissions of sulfur dioxide under paragraph (b)(6) of this section 
    differs from the amount of excess emissions determined under 
    Sec. 73.35(b) of this chapter based on the annual compliance 
    certification report. If the amounts differ, the Administrator will 
    determine: The number of allowances that should be deducted to offset 
    any increase in excess emissions or returned to account for any 
    decrease in excess emissions; and the amount of excess emissions 
    penalty (excluding interest) that should be paid or returned to account 
    for the change in excess emissions. The Administrator will deduct 
    immediately from the unit's compliance subaccount the amount of 
    allowances that he or she determines is necessary to offset any 
    increase in excess emissions or will return immediately to the unit's 
    compliance subaccount the amount of allowances that he or she 
    determines is necessary to account for any decrease in excess 
    emissions. The designated representative may identify the serial 
    numbers of the allowances to be deducted or returned. In the absence of 
    such identification, the deduction will be on a first-in, first-out 
    basis under Sec. 73.35(b)(2) of this chapter and the return will be at 
    the Administrator's discretion.

    introductory text and adding paragraph (d) to read as follows:
    
    
    Sec. 72.95  Allowance deduction formula.
    
    * * * * *
        Total allowances deducted = Tons emitted + Allowances surrendered 
    for underutilization + Allowances deducted for Phase I extensions + 
    Allowances deducted for substitution or compensating units
    
    Where:
    * * * * *
        (d) ``Allowances deducted for substitution or compensating units'' 
    is the total number of allowances calculated in accordance with the 
    surrender requirements specified under Sec. 72.41(d)(3) or 
    (e)(1)(iii)(B) or Sec. 72.43(d)(2).
