    ACTION: Proposed conditional approval.
    
    -----------------------------------------------------------------------
    
    SUMMARY: EPA is proposing conditional approval of a State 
    Implementation Plan (SIP) revision submitted by the State of Delaware. 
    This revision establishes and requires the implementation of a low 
    enhanced motor vehicle inspection and maintenance (I/M) program in the 
    counties of Kent and New Castle. The intended effect of this action is 
    to propose conditional approval of the Delaware enhanced motor vehicle 
    I/M program. EPA is proposing conditional approval because Delaware's 
    SIP revision is deficient in certain aspects with respect to the 
    requirements of the Clean Air Act and EPA's I/M program regulations. 
    EPA regards the following deficiencies of the Delaware program as those 
    most significantly affecting the program's operation: Lack of legal 
    authority, finalized program regulations, certain testing and quality 
    control procedures, waiver requirements; program evaluation 
    requirements, sufficient quality control procedures and requirements; 
    complete equipment specifications; specific enforcement requirements; 
    certain public information and consumer enforcement requirements; 
    certain public information and consumer protection requirements; 
    sufficient enforcement authority; sufficient test documentation through 
    test memoranda and procedural memoranda. EPA is currently working with 
    the State on correcting these deficiencies. Delaware conducted a public 
    hearing on December 18, 1996 on additional revisions to the Delaware I/
    M SIP which are intended to remedy some of the deficiencies noted in 
    this notice. However, today's rulemaking applies to Delaware's I/M SIP 
    submissions of February 24, 1995 and November 30, 1995 which are 
    currently pending before EPA. EPA expects that Delaware will work, 
    promptly to remedy these items, through future submissions necessary to 
    meet the I/M rule requirements. In this notice, EPA cites its concerns 
    with the Delaware I/M program. While some of these concerns are less 
    significant to the program's immediate success, they still need to be 
    corrected so as to achieve the program's full air quality protection 
    potential. This action is taken under section 110 of the Clean Air Act.
    
    DATES: Comments must be received on or before March 7, 1997.

    SUPPLEMENTARY INFORMATION:
    
    I. Introduction
    
        Motor vehicles are significant contributors of volatile organic 
    compounds (VOC), carbon monoxide (CO) and nitrogen oxide (NOX) 
    emissions. An important control measure to reduce these emissions is 
    the implementation of a motor vehicle I/M program. Despite being 
    subject to the most rigorous vehicle pollution control program in the 
    world, cars and trucks still create toxic contaminants, about half of 
    the ozone air pollution and nearly all of the carbon monoxide air 
    pollution in United States cities. Of all highway vehicles, passenger 
    cars and light-duty trucks emit most of the vehicle-related carbon 
    monoxide and ozone-forming hydrocarbons. They also emit substantial 
    amounts of nitrogen oxides and air toxics. Although the U.S. has made 
    progress in reducing emissions of these pollutants, total fleet 
    emissions remain high. This is because the number of vehicle miles 
    traveled on U.S. roads has doubled in the last 20 years to 2 trillion 
    miles per year, offsetting much of the technological progress in 
    vehicle emission control over the same two decades. Projections 
    indicate that the steady growth in vehicle travel will continue. 
    Ongoing efforts to reduce emissions from individual vehicles will be 
    necessary to achieve our air quality goals.
        Today's cars are absolutely dependent on properly functioning 
    emission controls to keep pollution levels low. Minor malfunctions in 
    the emission control system can increase emissions significantly, and 
    the average car on the road emits three to four times the new car 
    standard. Major malfunctions in the emission control system can cause 
    emissions to skyrocket. As a result, 10
    
    [[Page 5362]]
    
    to 30 percent of cars are causing the majority of the vehicle-related 
    pollution problem. Unfortunately, it is rarely obvious which cars fall 
    into this category, as the emissions themselves may not be noticeable 
    and emission control malfunctions do not necessarily affect vehicle 
    driveability.
        Effective I/M programs, however, can identify these problem cars 
    and assure their repair. I/M programs ensure that cars are properly 
    maintained during customer use. I/M produces emission reduction results 
    soon after the program is put in place. The Clean Air Act as amended in 
    1990 (herein referred to as the Act) requires that most polluted areas 
    adopt either ``basic'' or ``enhanced'' I/M programs, depending on the 
    severity of the problem and the population of the area. The moderate 
    ozone nonattainment areas, plus marginal ozone areas with existing or 
    previously required I/M programs, fall under the ``basic'' I/M 
    requirements. Enhanced programs are required in serious, severe, and 
    extreme ozone nonattainment areas with urbanized populations of 200,000 
    or more; CO areas that exceed a 12.7 parts per million (ppm) design 
    value 1 with urbanized populations of 100,000 or more in the 
    Northeast Ozone Transport Region (OTR).
    ---------------------------------------------------------------------------
    
        \1\  The air quality design value is estimated using EPA 
    guidance. Generally, the fourth highest monitored value with 3 
    complete years of data is selected as the ozone design value because 
    the standard allows one exceedance for each year. The highest of the 
    second high monitored values with 2 complete years of data is 
    selected as the carbon monoxide design value.
    ---------------------------------------------------------------------------
    
        ``Basic'' and ``enhanced'' I/M programs both achieve their 
    objective by identifying vehicles that have high emissions as a result 
    of one or more malfunctions, and by requiring them to be repaired. An 
    ``enhanced'' program covers more of the vehicles in operation, employs 
    inspection methods that are better at finding high emitting vehicles, 
    and has additional features to better assure that all vehicles are 
    tested properly and effectively repaired.
        The Act requires states to make changes to improve existing I/M 
    programs or to implement new ones for certain nonattainment areas. 
    Section 182(a)(2)(B) of the Act directed EPA to publish updated 
    guidance for I/M programs, taking into consideration findings of the 
    Administrator's audits and investigations of these programs. The Act 
    further requires each area to have an I/M program that incorporates 
    this guidance into the SIP. Based on these requirements, EPA 
    promulgated I/M regulations on November 5, 1992 (57 FR 52950, codified 
    at 40 Code of Federal Regulations (CFR) 51.350-51.373, herein referred 
    to as the November 1992 Rule. Flexibility amendments to this rule, 
    which provided for a low enhanced I/M performance standard were 
    published on September 18, 1995 (60 FR 48029) and additional I/M 
    flexibility amendments for qualified areas in the OTR were published on 
    July 25, 1996 (61 FR 39031).
        Under sections 182(c)(3), 187(a)(6) and 187(b)(1) of the Act, any 
    area having a 1980 Bureau of Census-Defined urbanized area populations 
    of 200,000 or more and that is either: (1) Designated as serious or 
    worse ozone nonattainment or (2) moderate or serious CO attainment 
    areas with a design value greater than 12.7 ppm. shall implement 
    enhanced I/M in the 1990 Census-defined urbanized area. The Act also 
    established the OTR in the Northeastern United States which includes 
    the States of Maine, Vermont, New Hampshire, Massachusetts, Rhode 
    Island, Connecticut, Pennsylvania, New York, New Jersey, Delaware, 
    Maryland, and Northern Virginia and the District of Columbia. Sections 
    182(c)(3) and 184(b)(1)(A) of the Act require the implementation of 
    enhanced I/M programs in all metropolitan statistical areas (MSAs) 
    located in the OTR that have a population of 100,000 or more people.
        EPA's rules for I/M established a low and high enhanced standard. 
    The high enhanced I/M program achieves a greater reduction in emissions 
    (approximately 36%) and uses a highly technical test method. The low 
    enhanced I/M performance standard provides flexibility for 
    nonattainment areas that are required to implement enhanced I/M 
    programs but which can meet the Act's emission reduction requirements 
    for reasonable further progress (commonly referred to as 15% plans) and 
    attainment from other sources without the stringency of the high 
    enhanced I/M performance standard (60 FR 48029). All other provisions 
    of the November 5, 1992 I/M rule, except as revised in 60 FR 48029 for 
    extension of waivers and expenditure requirements, remain applicable to 
    states available for low enhanced I/M. 40 CFR 51.35(g) provides that 
    states may select the low enhanced performance standard if they have an 
    approved SIP for 15%. In today's Federal Register EPA is also proposing 
    conditional approval of Delaware's 15% plan.
        The I/M regulation also establishes requirements for the following: 
    Network type and program evaluation; adequate tools and resources; test 
    frequency and convenience; vehicle coverage; test procedures and 
    standards; test equipment; quality control; waivers and compliance via 
    diagnostic inspection; motorist compliance enforcement; motorist 
    compliance enforcement program oversight; quality assurance; 
    enforcement against contractors, stations and inspectors; data 
    collection; data analysis and reporting; inspector training and 
    licensing or certification; public information and consumer protection; 
    improving repair effectiveness; compliance with recall notices; on-road 
    testing; SIP revisions; and implementation deadlines. The performance 
    standard for the high enhanced I/M program is different from the low 
    enhanced program in that the high enhanced performance standard is 
    based on high-technology transient test, known as IM240, for new 
    technology vehicles (i.e, those with closed-loop control and 
    especially, fuel injected engines), including a transient loaded 
    exhaust short test incorporating hydrocarbons (HC), CO and NOX 
    cutpoints, and evaporative system integrity (pressure) test and an 
    evaporative system performance (purge) test. The low enhanced 
    performance standard, however, allows for idle testing in place of 
    high-tech testing.
        Under the November 1992 I/M Rule enhanced I/M programs were 
    required to initially begin phased-in implementation by January 1, 
    1995, with final full implementation slated for January 1, 1996. Due to 
    recent EPA rule changes, and the flexibility afforded by the National 
    Highway Systems Designation Act of 1995 (NHA), EPA believes, as 
    explained below, that all states should be afforded extra time to begin 
    full implementation of their enhanced I/M programs.
    
    II. Background
    
        Delaware is part of the OTR and contains the following portions of 
    the MSA that have a population of 100,000 or more: The MSA containing 
    Kent and the MSA containing New Castle Counties. Section 182(c)(3) and 
    184(b)(1)(A) of the Act requires all states in the OTR region which 
    contain MSAs or parts thereof with populations of 100,000 or more, to 
    submit a SIP revision for an enhanced I/M program. Furthermore, both 
    Kent and New Castle Counties are part of the Philadelphia-Wilmington-
    Trenton severe ozone nonattainment area. Section 51.351(g) of the 
    November 1992 I/M rule as amended by 60 FR 48029 provides that states 
    may select the low enhanced performance standard if they have an 
    approved SIP for 15%. As previously stated, EPA is, today, also 
    proposing
    
    [[Page 5363]]
    
    conditional approval of Delaware's 15% plan.
        On February 17, 1995 the Delaware Department of Natural Resources 
    and Environmental Control (DNREC) officially submitted to EPA a 
    revision to the Delaware SIP for an I/M program in Delaware, Kent and 
    New Castle Counties. The submittal consisted of a copy of the final 
    regulations in Regulation Numbers 26 and 33 of the Delaware Regulations 
    Governing the Control of Air Pollution, by way of Secretary Order 
    number 95-A-0012. On November 30, 1995 Delaware officially submitted 
    the performance standard evaluation as a supplement to the February 17, 
    1995 SIP submittal. The performance standard evaluation provides for a 
    low enhanced I/M program. Regulation 26 provides for the requirement 
    that all repairs be done by a certified repair technician. Regulation 
    33 provides for pressure test and anti-tampering checks on vehicles in 
    Kent and New Castle Counties.
        EPA's summary of the requirements of the November 1992 I/M Rule as 
    found in 40 CFR 51.350 through 51.373, and EPA's analysis of Delaware's 
    submittal are outlined below. A more detailed analysis of Delaware's 
    submittal is contained in a Technical Support Document (TSD) dated 11/
    27/96 which is available from the Region III office, listed in the 
    ADDRESSES section. Parties desiring additional details on the federal 
    I/M regulation are referred to the November 5, 1992 Federal Register 
    notice (57 FR 52950) or 40 CFR 51.350-51.37, as well as the I/M 
    Flexibility Amendments in the September 18, 1995 Federal Register 
    notice (60 FR 48029) and the additional I/M flexibility amendments for 
    qualified areas in the OTR, published on July 25, 1996 at (61 FR 39031)
    
    III. EPA's Analysis of Delaware's Low Enhanced I/M Program
    
        As discussed above, section 182(c)(3), 184(b)(1)(A), 87(a)(6) and 
    187(b)(1) of the Act require that States adopt and implement 
    regulations for an enhanced I/M program in certain areas. Based upon 
    EPA's review of Delaware's submittal, EPA believes Delaware has not 
    completely satisfied all aspects of the Act and the November 1992 I/M 
    Rule. EPA has cited the deficiencies of Delaware's low enhanced I/M 
    program, below. EPA proposes to conditionally approve the SIP if 
    Delaware commits within 30 days of this proposal to correct the 
    deficiencies identified by this document by a date certain within 1 
    year of the final conditional ruling. If Delaware corrects the 
    deficiencies by that date, and submits a new SIP revision, EPA will 
    conduct a rulemaking to fully approve the revision. Each of the 
    conditions must be fulfilled by Delaware and submitted to EPA as an 
    amendment to Delaware's I/M SIP revision. If such commitment is not 
    made within 30 days, EPA proposes in the alternative to disapprove the 
    SIP revision. If Delaware does make a timely commitment, but the 
    conditions are not met by the specified date within 1 year, EPA 
    proposes that this rulemaking will convert to a final disapproval. EPA 
    would notify Delaware by letter that the conditions have not been met 
    and that the conditional approval has converted to a disapproval.
    
    Applicability--40 CFR 51.350
    
        Sections 182(c)(3) and 184(b)(1)(A) of the Act and 40 CFR 51.350 
    require all areas that are classified as serious or worse nonattainment 
    areas and states in the OTR which contain MSAs or parts thereof with 
    populations of 100,000 or more to implement an enhanced I/M program. 
    Areas classified as marginal for ozone or moderate for CO shall meet 
    the requirements of a basic I/M program. Delaware is part of the OTR. 
    Kent and New Castle are Delaware counties that fall under the November 
    1992 I/M Rule. Kent and New Castle Counties are classified as severe 
    nonattainment for ozone and are implementing a low enhanced I/M 
    program.
        The federal I/M regulation requires that legislation authorizing 
    the program shall not sunset prior to the attainment deadline. 
    Delaware's legislation, 7 Delaware Code, Chapter 67, Section 6702 
    provides authority to implement the program. However, this legislation 
    is open ended and does not specify a date certain up to which the 
    program is to continue. EPA needs confirmation through a commitment or 
    statement by an authorized Delaware official that the program shall 
    remain in effect for as long as required by law.
        Federal I/M regulation requires that SIPs include a list of the ZIP 
    codes of all areas covered by the I/M program. This is not contained in 
    the current Delaware SIP submittal. EPA needs to receive a submitted 
    document that details the ZIP codes of all areas covered by the I/M 
    program.
        Therefore, EPA proposes to conditionally approve the Delaware SIP 
    based upon a commitment from Delaware within 30 days, to provide a 
    statement from an authorized official that the authority to implement 
    Delaware's I/M program as stated above will continue through to 
    attainment and to provide ZIP code information for the affected 
    counties under the I/M program. Additional information needed to remedy 
    the deficiencies in this section is explained in Sec. 51.350 of the I/M 
    Rule and the list in the TSD prepared by EPA on this rulemaking.
    
    Enhanced I/M Performance Standard--40 CFR 51.351
    
        In accordance with the Act and with the November 1992 I/M Rule, the 
    enhanced I/M program must be designed and implemented to meet or exceed 
    a minimum performance standard, which is expressed as emission levels 
    in area-wide average grams per mile (gpm) for certain pollutants. The 
    performance standard shall be established using local characteristics, 
    such as vehicle mix and local fuel controls, and the following 
    parameters: network type, start date, test frequency, model year 
    coverage, vehicle type coverage, exhaust emission test type, emission 
    standards, emissions control device, evaporative system function 
    checks, stringency, waiver rate, compliance rate, and evaluation date. 
    The emission levels achieved by the Delaware's program design shall be 
    calculated using the most current version, at the time of submittal, of 
    the EPA mobile source emissions factor model. Areas shall meet the 
    performance standard for the pollutants which cause them to be subject 
    to enhanced I/M requirements. In the case of ozone nonattainment areas, 
    the performance standard must be met for both NOX and HC. The 
    Delaware submittal must meet the low enhanced I/M performance standard 
    for HC and NOX in Kent and New Castle Counties.
        The Delaware submittal includes a modeling demonstration of the 
    performance standard that uses the following program design parameters. 
    EPA here notes that not all of Delaware's parameter assumptions are 
    acceptable, and as a condition of this rulemaking Delaware must remodel 
    its program and demonstrate compliance with the I/M performance 
    standard:

    ------------------------------------------------------------------------
    
        The federal I/M rule requires on-road testing of at least 0.5% of 
    the subject vehicle population, or 20,000 whichever is less, as a 
    supplement to the periodic inspection required by the rule. Delaware 
    does not have adopted regulations that implement an on-road testing 
    program. Delaware will need to adopt regulations requiring on-road 
    testing. Therefore, EPA proposes to conditionally approve the Delaware 
    SIP based on receiving within 30 days of the publication of this 
    notice, Delaware's commitment to submit to EPA by a date certain, 
    within 1 year of the final conditional rulemaking, adopted regulations 
    that implement an on-road vehicle testing program as called out in 
    Sec. 51.351(b) of the November 1992 I/M Rule. Additional information 
    needed to remedy the deficiencies in this section is explained in 
    Sec. 51.351 of the I/M Rule and the list in the TSD.
    
    Network Type and Program Evaluation--40 CFR 51.353
    
        The enhanced program must include an ongoing evaluation to quantify 
    the emission reduction benefits of the program, and to determine if the 
    program is meeting the requirements of the Act and the federal I/M 
    regulations. The SIP shall include details on the program evaluation 
    and shall include a schedule for submittal of biennial evaluation 
    reports, data from a State monitored or administered mass emissions 
    test of at least 0.1% of the vehicles subject to inspection each year, 
    a description of the sampling methodology, the data collection and 
    analysis system and the legal authority enabling the evaluation 
    program. In addition to these requirements, Delaware is required, in 
    accordance with this section of the November 1992 I/M Rule, to provide 
    in the biennial report, the results of undercover surveys of inspector 
    effectiveness related to identifying vehicles in need of repair. Also, 
    Delaware is required, in its biennial reports, to provide local fleet 
    emissions factors in assessing the actual effectiveness of the I/M 
    program.
        The November 1992 I/M Rule requires that SIPs include a description 
    of the evaluation schedule and protocol, the sampling methodology, the 
    data collection and analysis system, the resources and personnel for 
    evaluation and related details of the evaluation program, and the legal 
    authority enabling the evaluation program.
        Delaware has legal authority to operate a motor vehicle program as 
    stated in 7 Delaware Code, Chapter 60, Section 6010. However, 
    Delaware's submittal contains no narrative description, regulations or 
    procedures to address program evaluation; the network type is not 
    specified; and there is no commitment that Delaware will in fact 
    evaluate the program.
        Regarding program evaluation elements, EPA needs to see evidence 
    through procedures and or regulation that the following elements are 
    addressed: (1) A provision for the first biennial evaluation to be 
    reported to EPA by July 1997; (2) a description of the evaluation 
    schedule, protocol, sampling methodology, data collection and analysis, 
    and the resources and personnel for the evaluation program.
        Therefore, EPA proposes to conditionally approve the Delaware SIP 
    based on receiving within 30 days of the publication of this notice, 
    Delaware's commitment to submit to EPA by a date certain, within 1 year 
    of the final conditional rulemaking, a description of the evaluation 
    schedule and protocol, the sampling methodology, the data collection 
    and analysis system, the resources and personnel for evaluation and 
    related details of the evaluation program, and the legal authority 
    enabling the evaluation program. Additional information needed to 
    remedy the deficiencies in this section is explained in Sec. 51.353 of 
    the I/M Rule and the checklist in the TSD.
    
    Adequate Tools and Resources--40 CFR 51.354
    
        The federal regulation requires Delaware to demonstrate that 
    adequate funding of the program is available. A portion of the test fee 
    or separately assessed per vehicle fee shall be collected, placed in a 
    dedicated fund and used to finance the program. Alternative funding 
    approaches are acceptable if demonstrated that the funding can be 
    maintained. Reliance on funding from Delaware or local general fund is 
    not acceptable unless doing otherwise would be a violation of 
    Delaware's constitution. The SIP shall include a detailed budget plan 
    which describes the source of funds for personnel, program 
    administration, program enforcement, and purchase of equipment. The SIP 
    shall also detail the number of personnel dedicated to the quality 
    assurance program, data analysis, program administration, enforcement, 
    pubic education and assistance and other necessary functions.
        Delaware's SIP submittal does not provide a description of 
    resources. EPA is aware that Delaware has funding through the 1993 
    House Bill 360 which dedicated 2.8 million dollars from state traffic 
    fines/violations to be used for the enhanced I/M program. However, a 
    copy of the enabling legislation for these funds was not included in 
    Delaware's submittals pending before EPA. EPA needs to receive a copy 
    of the document under official cover as well as additional details on 
    how the program is funded. It is not clear what monies are used for 
    current program operation, pressure test equipment, and where funding 
    will come from to purchase equipment to perform the required mass based 
    transient test. Delaware needs to provide these details.
        Therefore, EPA proposes to conditionally approve the Delaware SIP 
    based on receiving within 30 days of the publication of this notice, 
    Delaware's commitment to submit to EPA by a date
    
    [[Page 5365]]
    
    certain, within 1 year of the final conditional rulemaking, a detailed 
    budget plan which describes the source of funds for personnel, program 
    administration, program enforcement, and purchase, of equipment. This 
    submission must also include information on the number of personnel 
    dedicated to the quality assurance program, data analysis, program 
    administration, enforcement, public education and assistance and other 
    necessary functions. Additional information required to remedy the 
    deficiencies in this section is explained in Sec. 51.354 of the I/M 
    Rule and in the TSD.
    
    Test Frequency and Convenience--40 CFR 51.355
    
        The enhanced I/M performance standard assumes an annual test 
    frequency, however, other schedules may be approved if the performance 
    standard is achieved. The SIP shall describe the test year selection 
    scheme, how the test frequency is integrated into the enforcement 
    process and shall include the legal authority, regulations or contract 
    provisions to implement and enforce the test frequency. The program 
    shall be designed to provide convenient service to the motorist by 
    ensuring short wait times, short driving distances and regular testing 
    hours.
        Delaware has stated that its program is a biennial testing program, 
    but Delaware does not have adopted regulations or a narrative 
    description of the program test frequency or what mechanisms are in 
    place to insure short wait times for the motorist during program 
    operation. Furthermore, the Delaware SIP does not identify safeguards 
    to ensure vehicles will be tested on schedule. The Delaware SIP 
    provides no regulations that require testing stations to test any 
    subject vehicle presented for a test during the station's operating 
    hours.
        Therefore, EPA proposes to conditionally approve the Delaware SIP 
    based on receiving within 30 days of the publication of this notice, 
    Delaware's commitment to submit to EPA by a date certain, within 1 year 
    of the final conditional rulemaking, a description of the test year 
    selection scheme, and how the test frequency is integrated into the 
    enforcement process. This description must include the legal authority, 
    regulations or contract provisions to implement and enforce the test 
    frequency. The program must be designed to provide convenient service 
    to the motorist by ensuring short wait times, short driving distances 
    and regular testing hours. Additional information needed to remedy the 
    deficiencies in this section is explained in Sec. 51.355 of the I/M 
    Rule and in the TSD.
    
    Vehicle Coverage--40 CFR 51.356
    
        The performance standard for enhanced I/M programs assumes coverage 
    of all 1968 and later model year light duty vehicles and light duty 
    trucks up to 8,500 pounds Gross Vehicle Weight Rating (GVWR), and 
    includes vehicles operating on all fuel types. Other levels of coverage 
    may be approved if the necessary emission reductions are achieved. 
    Vehicles registered or required to be registered within the I/M program 
    area boundaries, and fleets primarily operated within the I/M program 
    area boundaries and belonging to the covered model years and vehicle 
    classes comprise the subject vehicles. Fleets may be officially 
    inspected outside of the normal I/M program test facilities, if such 
    alternatives are approved by the program administration, but shall be 
    subject to the same test requirements using the same quality control 
    standards as non-fleet vehicles and shall be inspected in independent, 
    test-only facilities, according to the requirements of 40 CFR 
    51.353(a). Vehicles which are operated on federal installations located 
    within an I/M program area shall be tested, regardless of whether the 
    vehicles are registered in state or local I/M area.
        The federal I/M program regulation requires that SIPs include the 
    legal authority or rule necessary to implement and enforce the vehicle 
    coverage requirement, a detailed description of the number and types of 
    vehicles to be covered by the program, and a plan for how those 
    vehicles are to be identified including vehicles that are routinely 
    operated in the area but that may not be registered in the area. There 
    must also be a description of any special exemptions including the 
    percentage and number of vehicles to be impacted by the exemption.
        Delaware's current submission provides no breakdown by model year 
    and weight. Since only gasoline powered internal combustion engines are 
    subject to the program as provided in Delaware regulations 26 and 33, 
    fuel type is not an issue. Additionally, the Delaware SIP submittal 
    pending before EPA does not provide for an accounting for registered 
    vehicles and those required to be registered in order to provide an 
    estimate of unregistered vehicles subject to the I/M program. It is 
    assumed that fleet vehicles are covered in the current regulations, 
    however, no provisions for fleet testing are in the regulations and no 
    authority to provide for fleet testing is given. There are no 
    provisions to address testing vehicles registered in other program 
    areas. The Delaware SIP sumittal does not address the federal fleet 
    inspection program. Delaware's regulations provide for vehicle 
    exemptions from its I/M program, however, the Delaware SIP submittal 
    does not include an estimate of vehicles or a percentage of the subject 
    fleet and no accounting is made in Delaware's emissions reduction 
    analysis.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, a description of vehicles covered by 
    Delaware's I/M program, broken down by model year and weight; an 
    accounting for registered vehicles and those required to be registered 
    in order to provide an estimate of unregistered vehicles subject to the 
    I/M program. Delaware also needs to submit provisions in its 
    regulations that provide for fleet testing; testing vehicles registered 
    in other program areas; and provide the legal authority or rules 
    necessary to implement fleet testing. With regard to the fleet 
    inspection program, Delaware needs to develop regulations and 
    procedures that address fleet inspections and account for this in its 
    vehicle coverage and in the modeling of the performance standard. 
    Delaware also needs to provide information on exempted vehicles 
    regarding number, fleet percentage and account for them in its 
    emissions reduction analysis. Additional information needed to remedy 
    deficiencies noted in this section is explained in Sec. 51.356 of the 
    I/M Rule and in the TSD.
    
    Test Procedures and Standards--40 CFR 51.357
    
        Written test procedures and pass/fail standards shall be 
    established and followed for each model year and vehicle type included 
    in the program. Test procedures and standards are detailed in 40 CFR 
    51.357 and in the EPA document entitled ``High-Tech I/M Test 
    Procedures, Emissions Standards, Quality Control Requirements, and 
    Equipment Specifications'', EPA-AA-EPSD-IM-93-1, dated April 1994. The 
    federal I/M regulations also require vehicles that have been altered 
    from their original certified configuration (i.e., engine or fuel 
    switching) to be tested in the same manner as other subject vehicles.
        Delaware has provided detailed test procedures for each test as 
    well as pass/
    
    [[Page 5366]]
    
    fail standards for each applicable model year for each test. However, 
    Delaware needs to assure certain procedures conform with procedures 
    contained in Appendix B to Subpart S of the November 5, 1992 November 
    1992 I/M Rule. Also regulations/procedures need to be provided that: 
    (1) Ensure that initial tests are performed with no prior repair or 
    adjustment at the facility; (2) provide access to permit owner 
    observation; (3) provide for rejection of vehicles with missing 
    components or unsafe conditions; (4) provide for appropriate retesting 
    of primary and secondary components; and (5) address fuel and engine 
    switching. Delaware must ensure that its evaporative test standards 
    match EPA approved standards.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures that address the 
    above deficiencies. Additional information needed to remedy the 
    deficiencies in this section is explained in Sec. 51.357 of the I/M 
    Rule and in the TSD.
    
    Test Equipment--40 CFR 51.358
    
        Computerized test systems are required for performing any 
    measurement on subject vehicles. The federal I/M regulation requires 
    that SIP submissions include written technical specifications for all 
    test equipment used in the program. The specifications shall describe 
    the emission analysis process, the necessary test equipment, the 
    required features, and written acceptance testing criteria and 
    procedures.
        Delaware's submission contains written technical specifications 
    that addresses pass/fail criteria, calibration adjustments and quality 
    control for idle testing. However no test specifications are provided 
    for the idle or pressure tests. The State's submission does not 
    describe equipment acceptance testing criteria and procedures. The test 
    equipment is capable of testing all subject vehicles, however written 
    test equipment specifications are not contained in the submission. 
    Additionally, there is no commitment to update test equipment and no 
    description of the test system configuration.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures that address the 
    general deficiencies noted above. Additional information needed to 
    remedy the deficiencies in this section is explained in Sec. 51.358 of 
    the I/M Rule and in the TSD.
    
    Quality Control--40 CFR 51.359
    
        Quality control measures shall insure that emissions measurement 
    equipment is calibrated and maintained properly and that inspection, 
    calibration records, and control charts are accurately created, 
    recorded and maintained.
        Delaware has provided a description of quality control measures for 
    emissions measurement equipment, however, the remaining requirements of 
    this section have not been addressed. These include but are not limited 
    to: A quality control procedures manual or related document; proper 
    calibration measures and associated record keeping; preventive 
    maintenance measures/provisions for proper recording of quality control 
    information. In addition, the Delaware SIP does not contain provisions 
    for maintenance, calibration and insuring test accuracy; equipment 
    specifications; for steady-state and evaporative test equipment.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures and/or documents 
    that address the general deficiencies noted above. Additional 
    information needed to remedy the deficiencies in this section is 
    explained in Sec. 51.359 of the I/M Rule and the checklist in the TSD.
    
    Waivers & Compliance via Diagnostic Inspection--40 CFR 51.360
    
        The federal I/M regulations allows for the issuance of a waiver, 
    which is a form of compliance with the program requirements that allows 
    a motorist to comply without meeting the appropriate test standards. 
    For enhanced I/M programs, an expenditure of at least $450 in repairs, 
    adjusted annually to reflect the change in the Consumer Price Index 
    (CPI) as compared to the CPI for 1989, is required in order to qualify 
    for a waiver. Waivers can only be issued after a vehicle has failed a 
    retest performed after all qualifying repairs have been made. Any 
    available warranty coverage must be used to obtain repairs before 
    expenditures can be counted toward the cost limit. Tampering related 
    repairs shall not be applied toward the cost limit. Repairs must be 
    appropriate to the cause of the test failure. The federal regulation 
    allows for compliance via a diagnostic inspection after failing a 
    retest on emissions and requires quality control of waiver assurance. 
    The SIP must set a maximum waiver rate and must describe corrective 
    action that would be taken if the waiver rate exceeds that committed to 
    in the SIP.
        Delaware has provisions in its regulations for issuance of waivers 
    and has demonstrated that it has the necessary legal authority to issue 
    the waivers and administrate the waiver system. It establishes the 
    minimum dollar expenditure amounts for waivers to be issued in the 
    areas that are required to implement the basic I/M program. However, in 
    Kent and New Castle Counties, where the low enhanced program applies, 
    the same basic waiver rate is in place. This does not meet the minimum 
    requirement of $450 which is a statutory requirement of the Act.
        Time extensions are part of Delaware's rule provisions, but these 
    provisions only partially fulfill the requirements regarding time 
    extensions under this section. The Delaware SIP provides for the 
    performance of a documented physical and functional analysis and for 
    the cut point requirements which are consistent with EPA requirements. 
    However, the Delaware SIP contains provisions that only partially 
    fulfill the requirements for the quality control of waiver issuance.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures and/or documents 
    that address the general deficiencies mentioned above. Additional 
    information needed to remedy the deficiencies in this section is 
    explained in Sec. 51.360 of the I/M Rule and in the TSD.
    
    Motorist Compliance Enforcement--40 CFR 51.361
    
        The federal regulation requires that compliance shall be ensured 
    through the denial of motor vehicle registration in enhanced I/M 
    programs unless an exception for use of an existing alternative is 
    approved. SIPs shall provide information concerning the enforcement 
    process, legal authority to implementation and enforce the program, and 
    a commitment to a compliance rate to be used for modeling purposes and 
    to be maintained in practice.
    
    [[Page 5367]]
    
        As a condition for this approval, Delaware needs to provide EPA 
    with the specific details of its Motorist Compliance Enforcement 
    program. Although Delaware has a registration denial system, under the 
    basic I/M program, no details have been provided. The SIP submittal 
    must include a commitment to maintain a specified enforcement level to 
    be used for modeling purposes.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures and/or documents 
    that address the general deficiencies noted above. Additional 
    information needed to remedy the deficiencies noted above is explained 
    in Sec. 51.361 of the I/M Rule and in the TSD.
    
    Motorist Compliance Enforcement Program Oversight--40 CFR 51.362
    
        The federal I/M regulation requires that the enforcement program 
    shall be audited regularly and shall follow effective program 
    management practices, including adjustments to improve operation when 
    necessary. The SIP shall include quality control and quality assurance 
    procedures to be used to insure the effective overall performance of 
    the enforcement system. An information management system shall be 
    established which will characterize, evaluate and enforce the program.
        Although Delaware has motorist compliance enforcement oversight 
    procedures/regulations, they were not provided in the SIP submittal, 
    specifically, 7 Delaware Code, Chapter 67 for enforcement procedures. 
    These need to be provided to EPA along with the procedures manual.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures and/or documents 
    that address the general deficiencies noted above. Additional 
    information needed to remedy the deficiencies noted above is explained 
    in Sec. 51.362 of the I/M Rule and in the TSD.
    
    Quality Assurance--40 CFR 51.363
    
        An ongoing quality assurance program shall be implemented to 
    discover, correct, and prevent fraud, waste and abuse in the program. 
    The program shall include covert and overt performance audits of the 
    inspectors, audits of station and inspector records, equipment audits, 
    and formal training of all State I/M enforcement officials and 
    auditors. A description of the quality assurance program which includes 
    written procedure manuals on the above discussed items must be 
    submitted as part of the SIP.
        As a condition for approval, Delaware needs to provide the EPA 
    details of its existing quality assurance program that fulfill the 
    detailed requirements listed in Sec. 51.363 of the I/M rule.
        EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, regulations/procedures and/or documents 
    that address the general deficiencies of this section. Additional 
    information needed to remedy the deficiencies in this section is 
    explained in Sec. 51.363 of the I/M Rule and in the TSD.
    
    Enforcement Against Contractors, Stations and Inspectors--40 CFR 51.364
    
        Enforcement against licensed stations, contractors, and inspectors 
    shall include swift, sure, effective and consistent penalties for 
    violation of program requirements. The federal I/M regulation requires 
    the establishment of minimum penalties for violations of program rules 
    and procedures which can be imposed against stations, contractors and 
    inspectors. The legal authority for establishing and imposing 
    penalties, civil fines, license suspensions and revocations must be 
    included in the SIP. State quality assurance officials shall have the 
    authority to temporarily suspend station and/or inspector licenses 
    immediately upon finding a violation that directly affects emission 
    reduction benefits, unless constitutionally prohibited. An official 
    opinion explaining any state constitutional impediments to immediate 
    suspension authority must be included in the submittal. The SIP shall 
    describe the administrative and judicial procedures and 
    responsibilities relevant to the enforcement process, including which 
    agencies, courts and jurisdictions are involved, who will prosecute and 
    adjudicate cases and the resources and sources of those resources which 
    will support this function.
        7 Delaware Code, Chapter 60, section 6010 provides general 
    authority to Secretary to adopt regulations necessary to implement 
    program. However, Delaware has provided no procedures that address any 
    requirements of this section. No specific regulation is provided for 
    enforcement against stations, inspectors, or contractors, nor is a 
    penalty schedule provided. Delaware has not demonstrated that it has 
    existing regulations under the basic I/M program.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations, rules and procedures 
    that address the deficiencies of this section. Additional information 
    needed to remedy the deficiencies in this section is explained in 
    Sec. 51.364 of the I/M Rule and in the TSD.
    
    Data Collection Section--40 CFR 51.365
    
        Accurate data collection is essential to the management, evaluation 
    and enforcement of an I/M program. The federal I/M regulation requires 
    data to be gathered on each individual test conducted and on the 
    results of the quality control checks of test equipment required under 
    40 CFR Sec. 51.359.
        Delaware's SIP did not address data collection. Delaware needs to 
    either demonstrate that it has existing data procedures that meet the 
    requirements of this section or develop and submit regulations/
    provisions/procedures that meet this requirement.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.365 
    of the I/M Rule and in the TSD.
    
    Data Analysis and Reporting--40 CFR 51.366
    
        Data analysis and reporting are required to allow for monitoring 
    and evaluation of the program by Delaware and EPA. The federal I/M 
    regulation requires annual reports to be submitted which provide 
    information and statistics and which summarize activities performed for 
    each of the following programs: Testing, quality assurance, quality 
    control and enforcement. These reports are to be submitted by July of 
    each year and shall provide statistics for the period from January to 
    December of the previous year. A separate biennial report shall be 
    submitted to EPA which addresses changes in program design, 
    regulations,
    
    [[Page 5368]]
    
    legal authority, program procedures and any weaknesses in the program 
    found during the two year period and how these problems will be or have 
    been corrected.
        Delaware's SIP did not address data analysis and reporting 
    provisions. Delaware needs to either show EPA that it has existing data 
    analysis procedures that meet the requirements of this section or 
    develop and submit regulations/provisions/ procedures that meet this 
    requirement.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.366 
    of the I/M Rule and in the TSD.
    
    Inspector Training and Licensing or Certification--40 CFR 51.367
    
        The federal I/M regulations requires all inspectors to be formally 
    trained and licensed or certified to perform inspections.
        Regulation 26, Section 8 and Regulation 33, Section 8 requires 
    certification of motor vehicle officers. These regulations also have 
    provisions stipulating that motor vehicle officers complete a training 
    course approved by the Delaware Division of Motor Vehicles. However, no 
    description of the training course is given in the submission.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.367 
    of the I/M Rule and in the TSD.
    
    Public Information and Consumer Protection--40 CFR 51.368
    
        The federal I/M regulation requires the SIP to include public 
    information and consumer protection.
        Delaware needs to provide provisions/measures that it will 
    implement to protect the consumer and provide for public awareness.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.368 
    of the I/M Rule and in the TSD.
    
    Improving Repair Effectiveness--40 CFR 51.369
    
        Effective repairs are the key to achieving program goals. The 
    federal regulation requires states to take steps to ensure that the 
    capability exists in the repair industry to repair vehicles. The SIP 
    must include a description of the technical assistance program to be 
    implemented, a description of the procedures and criteria to be used in 
    meeting the performance monitoring requirements required in the federal 
    regulation and a description of the repair technician training 
    resources available in the community.
        EPA understands that the Delaware Department of Natural Resources 
    and Environmental Control (DNREC) is jointly developing a technician 
    training course with the Delaware Community College. The Delaware SIP 
    must include information on this program as well as provisions for 
    monitoring performance of repair facilities.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.369 
    of the I/M Rule and in the TSD.
    
    Compliance with Recall Notices--40 CFR 51.370
    
        The federal regulation requires that Delawares establish methods to 
    ensure that vehicles which are subject to enhanced I/M and are included 
    in an emission related recall receive the required repairs prior to 
    completing the emission test and/or renewing the vehicle registration.
        Delaware must address all the provisions for recall notices under 
    the federal regulation and noted in the TSD and as required under 
    Sec. 51.370 of the November 1992 I/M Rule.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies in this Section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.370 
    of the I/M Rule and in the TSD.
    
    On-Road Testing--40 CFR 51.371
    
        On-road testing is required in enhanced I/M areas. The use of 
    either remote sensing devices (RSD) or roadside pullovers including 
    tailpipe emission testing can be used to meet the federal regulations. 
    The program must include on-road testing of 0.5% of the subject fleet 
    or 20,000 vehicles, whichever is less, in the nonattainment area or the 
    I/M program area. Motorists that have passed an emissions test and are 
    found to be high emitters as a result of an on-road test shall be 
    required to pass an out-of-cycle test.
        No legal authority to implement an on-road testing program was 
    included in the Delaware SIP. The general authority to implement a 
    program may be sufficient to require on-road testing, however, Delaware 
    has no regulations in place to implement on-road testing.
        The EPA proposes to conditionally approve the Delaware SIP based on 
    receiving within 30 days of the publication of this notice, Delaware's 
    commitment to submit to EPA by a date certain, within 1 year of the 
    final conditional rulemaking, adopted regulations/procedures that 
    address the deficiencies of this section. Additional information needed 
    to remedy the deficiencies in this section is explained in Sec. 51.371 
    of the I/M Rule and in the TSD.
    
    State Implementation Plan Submittals/ Submission Deadlines--40 CFR 
    51.372 through 51.373
    
        Delaware's submittal contains the following: (1) The legislative 
    authority to implement the program; (2) Regulation 33 that adds a 
    requirement for a pressure test and anti-tampering checks on light duty 
    vehicles 1968 and newer and light duty trucks 1970 and newer in Kent 
    and New Castle Counties; (3) Regulation 26 that adds a requirement that 
    repairs on 1981 and later model year vehicles be performed by certified 
    repair technicians to qualify for a waiver. This program became 
    effective on January 1, 1997; and (4) the low enhanced performance 
    standard evaluation. Delaware has indicated that its pressure test and 
    anti-tampering program was effective as of January 1, 1995.
    
    [[Page 5369]]
    
        Delaware has demonstrated that the program meets the low-enhanced 
    performance standard. Delaware has shown that program will achieve an 
    air quality benefit. However, there are some specific administrative 
    requirements of the rule that they have not addressed. Delaware has not 
    adequately addressed: The waiver requirements; on-road testing 
    requirements; program evaluation using mass based transient test 
    procedure; specifics on network type and test frequency; sufficient 
    quality control procedures and requirements; complete equipment 
    specifications; specific enforcement requirements; public information 
    and consumer protection requirements; sufficient enforcement authority; 
    sufficient test document through test memoranda and procedural 
    memoranda.
        EPA understands that Delaware has adopted certain legislation and 
    procedures that were not included in the submittals pending before EPA. 
    Once legislation, regulations and/or procedures have gone through the 
    adoption process, they will need to be officially submitted to EPA as a 
    SIP revision supplement to the I/M SIP. Where new regulations/
    procedures are developed, the public notice and hearing process in 
    section 110 of Act must be followed. EPA has a list of missing 
    procedural manuals and enabling legislation in the TSD prepared on this 
    rulemaking. EPA believes that most of the noted deficiencies can be 
    addressed through regulation amendments and procedure manuals. The one 
    exception is the lack of provisions establishing a $450 waiver limit as 
    prescribed in the Act. All states with enhanced programs are required 
    to have this limit. EPA also remains concerned about how Delaware can 
    maintain a 3% waiver limit using a $200/$75 waiver amount. EPA believes 
    that the extension of the waiver deadline called out in the I/M rule, 
    as revised in 60 FR 48029, will afford Delaware the opportunity to 
    improve technician training so that by 1998, the majority of vehicles 
    would be repaired below the CPI adjusted $450 minimum waiver amount. 
    Nevertheless, Delaware must take corrective action to address the 
    waiver requirements and must also must take corrective action if the 
    waiver rate exceeds that provided for in the Delaware SIP.
        Therefore, EPA proposes to conditionally approve the Delaware SIP 
    based upon a commitment from Delaware within 30 days, to adopt and 
    submit final regulations to EPA and cure all of the deficiencies 
    related to this section of the November 1992 I/M Rule as explained 
    above, by a date certain within 1 year. If Delaware fails to make the 
    commitment, EPA proposes in the alternative to disapprove the SIP. If 
    Delaware fails to meet the condition by the date specified, EPA 
    proposes to convert this rule making to a disapproval at that time by 
    letter.
        EPA's review of the material indicates that with the conditions 
    described above, Delaware has adopted a low enhanced I/M program in 
    accordance with the requirements of the Act. EPA is proposing to 
    conditionally approve the Delaware I/M SIP revision which was submitted 
    to this office on February 24, 1995 and November 30, 1995 subject to 
    the conditions described above. EPA is soliciting public comments on 
    the issues discussed in this notice or on other relevant matters. 
    Interested parties may participate in the Federal rulemaking procedure 
    by submitting written comments to the EPA Regional offices listed in 
    the Addresses section of this notice.
    
    Proposed Action
    
        EPA proposes to conditionally approve the SIP if Delaware commits 
    within 30 days of this proposal to correct the deficiencies identified 
    by this document by a date certain within 1 year of the final 
    conditional ruling. If Delaware corrects the deficiencies by that date, 
    and submits a new SIP revision, EPA will conduct rulemaking to fully 
    approve the revision. Each of the conditions must be fulfilled by 
    Delaware and submitted to EPA as an amendment to Delaware's I/M SIP 
    revision. If such commitment is not made within 30 days, EPA proposes 
    in the alternative to disapprove the SIP revision. If Delaware does 
    make a timely commitment, but the conditions are not met by the 
    specified date within 1 year, EPA proposes that this rulemaking will 
    convert to a final disapproval. EPA would notify Delaware by letter 
    that the conditions have not been met and that the conditional approval 
    has converted to a disapproval.
        Under the Regulatory Flexibility Act, 5 U.S.C. 600 et seq., EPA 
    must prepare a regulatory flexibility analysis assessing the impact of 
    any proposed or final rule on small entities. 5 U.S.C., 603 and 604. 
    Alternatively, EPA may certify that the rule will not have a 
    significant impact on a substantial number of small entities. Small 
    entities include small businesses, small not-for-profit enterprises, 
    and government entities with jurisdiction over populations of less than 
    50,000.
        SIP approvals under section 110 and subchapter I, part D of the 
    requirements that Delaware is already imposing. Therefore, because the 
    Federal SIP approval does not impose any new requirements, EPA 
    certifies that it does not have a significant impact on any small 
    entities affected. Moreover, due to the nature of the Federal-State 
    relationship under the Act, preparation of a flexibility analysis would 
    constitute Federal inquiry into the economic reasonableness of State 
    action. The Act forbids EPA to base its actions concerning SIPs on such 
    grounds. Union Electric Co. v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 
    42 U.S.C. 7410(a)(2).
        If the conditional approval is converted to a disapproval under 
    section 110(k), based on Delaware's failure to meet the commitment, it 
    will not affect any existing State requirements applicable to small 
    entities. Federal disapproval of Delaware's submittal would not affect 
    its state-enforceability. Moreover, EPA's disapproval of the submittal 
    would not impose a new Federal requirement. Therefore, EPA certifies 
    that should this approval convert to a disapproval, this disapproval 
    action would not have a significant impact on a substantial number of 
    small entities because it would not remove existing requirements nor 
    would it substitute a new federal requirement.
        Under section 202 of the Unfunded Mandates Reform Act of 1995. 
    (``Unfunded Mandates Act''), signed into law on March 22, 1995. EPA 
    must prepare a budgetary impact statement to accompany any proposed or 
    final that includes a Federal mandate that may result in estimated 
    costs to Delaware, local, or tribal governments in the aggregate; or to 
    the private sector, of $100 million or more. Under section 205, EPA 
    must select the most cost-effective and least burdensome alternative 
    that achieves the objectives of the rule and is consistent with 
    statutory requirements. Section 203 requires EPA to establish a plan 
    for informing and advising any small governments that may be 
    significantly or uniquely impacted by the rule.
        EPA has determined that the approval action proposed/promulgated 
    does not include a Federal mandate that may result in estimated costs 
    of $100 million or more to either State, local, or tribal governments 
    in the aggregate, or to the private sector. This Federal action 
    approves requirements under State or local law, and imposes no new 
    Federal requirements. Accordingly, no additional costs to State, local, 
    or tribal governments, or to the private sector, result from this 
    action.
        This action has been classified as a Table 3 action for signature 
    by the

    Regional Administrator under the procedures published in the Federal 
    Register on January 19, 1989 (54 FR 2214-2225), as revised by a July 
    10, 1995 memorandum from Mary Nichols, Assistant Administrator for Air 
    and Radiation. The Office of Management and Budget (OMB) has exempted 
    this regulatory action from E.O. 12866 review.
        If Delaware fails to meet any of the conditions of this approval 
    action, the EPA Regional Administrator would directly make a finding, 
    by letter, that the conditional approval had converted to a disapproval 
    and the clock for imposition of sanctions under section 179(a) of the 
    Act would start as of the date of the letter. Subsequently, a notice 
    would be published in the Federal Register announcing that the SIP 
    revision has been disapproved.
        The Administrator's decision to approve or disapprove the Delaware 
    I/M SIP revision will be based on whether it meets the requirements of 
    section 110(a)(2) (A)-(K) of the Clean Air Act, as amended, and EPA 
    regulations in 40 CFR Part 51.
