ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: The EPA is proposing to approve portions and to conditionally approve other portions of a State Implementation Plan (SIP) revision submitted by the State of Wisconsin on November 15, 1993, if the State submits certain items prior to final action. This revision establishes and requires the implementation of an enhanced motor vehicle inspection and maintenance (I/M) program in the Milwaukee Severe ozone nonattainment area, which has 17 years to attain the National Ambient Air Quality Standards (NAAQS) pursuant to section 181(a)(2) of the Clean Air Act (Act), and the Sheboygan Moderate ozone nonattainment area. This action is being taken under section 110 of the Act. Should the State fail to timely submit the items described below, EPA is proposing in the alternative to disapprove or conditionally approve the SIP. DATES: Comments must be received on or before August 15, 1994. ADDRESSES: Comments may be mailed to: Carlton Nash, United States Environmental Protection Agency, Region 5, Air and Radiation Division, Air Toxics and Radiation Branch, Regulation Development Section, 77 West Jackson Boulevard, Chicago, Illinois 60604. Copies of the documents relevant to this action are available at the above address for public inspection during normal business hours. FOR FURTHER INFORMATION CONTACT: John M. Mooney, (312) 886-6043. 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 inspection and maintenance (I/M) program. Despite being subject to the most rigorous vehicle pollution control program in the world, cars and trucks still create about half of the ozone air pollution and nearly all of the carbon monoxide and other toxic contaminant air pollution in U.S. cities. Of all highway vehicles, passenger cars and light 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 travelled 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 2 decades. Projections indicate that the steady growth in vehicle travel will continue. Today's cars are absolutely dependent on properly functioning emission controls to reduce pollution levels. 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 to 30 percent of cars are causing a significantly larger percentage 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 the performance of the vehicle. Effective I/M programs, however, can identify these problem cars and assure their repair. I/M programs ensure that cars are properly maintained, producing emission reductions soon after the program is put in place. EPA projects that ``enhanced'' I/M programs in the most polluted cities around the country would cut vehicle VOC emissions by 32 percent, at a cost of about $12.50 per vehicle per year. This represents a major step toward fulfilling, at a relatively low cost, the Act's (the Act) requirement that the most seriously polluted cities achieve a 24 percent overall emissions reduction by 2000. The Clean Air Act as amended in 1990 requires that most polluted cities 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, as well as Marginal ozone areas with existing or previously required I/M programs, fall under the ``basic'' I/M requirements. Enhanced programs will be 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 200,000 or more; and all metropolitan statistical areas (MSA) with 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 objectives by identifying vehicles that have high emissions as a result of one or more malfunctions, and requiring them to be repaired. An ``enhanced'' program covers more of the vehicles in operation, employs inspection methods better suited to 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 requires EPA to publish updated guidance for State I/M programs, taking into consideration findings of the Administrator's audits and investigations of these programs. The Act further requires each area required to have an I/M program to incorporate 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) parts 51.350-51.373). 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 population of 200,000 or more and that is designated as either: (1) a serious or worse ozone nonattainment area or (2) a moderate or serious CO nonattainment areas with a design value greater than 12.7 ppm, shall implement enhanced I/M in the 1990 Census-defined urbanized area. The Act requires basic I/M programs to be implemented in the 1990 Census-defined urbanized area of the following nonattainment areas: (1) Any area which is classified as moderate ozone nonattainment and is not required to implement enhanced I/M, or (2) any area outside the OTR that is classified as serious or worse ozone nonattainment or moderate or serious CO nonattainment with a design value greater than 12.7 ppm and having a 1990 Census-defined urbanized area population of less than 200,000. Any areas classified as marginal ozone nonattainment or moderate CO nonattainment with a design value of 12.7 ppm or less shall continue operating existing programs that are part of an approved SIP as of November 15, 1990, or implement the basic program required for the area by the pre-Amended Act, and shall update the program to meet the basic I/M requirements set forth in 40 CFR parts 51.350-373. The I/M regulation establishes minimum performance standards for basic and enhanced I/M programs as well as 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 basic I/M programs remains the same as it has been since initial I/M policy was established in 1978, pursuant to the 1977 amendments to the Act. The performance standard for enhanced I/M programs is based on a high-technology 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, an evaporative system integrity (pressure) test and an evaporative system performance (purge) test. The Federal regulation requires enhanced I/M programs to be implemented by January 1, 1995, except for: (1) Existing test-and-repair programs which may test 30 percent of the subject fleet in the test-only system during 1995 and test all subject vehicles in the test-only system beginning January 1, 1996 (during the phase in period, existing requirements may continue to apply for the test-and-repair portion of the program until it is phased out by January 1, 1996) or (2) Areas starting new test-only programs and those with existing test-only programs may phase in the new test procedures between January 1, 1995 and January 1, 1996; however, all other program requirements must be fully implemented by January 1, 1995. II. Background The State of Wisconsin currently contains 2 ozone nonattainment areas which are required to implement I/M programs in accordance with the Act. The Milwaukee severe-17 ozone nonattainment area contains the Milwaukee-Racine MSA which has a 1980 Census-defined population of 1,572,000 and therefore must implement an enhanced I/M program. The Sheboygan moderate ozone nonattainment area contains the Sheboygan MSA and, as a result, is subject to the basic I/M requirements. 40 CFR part 51.372(b)(2)) requires affected States to submit full I/M SIP revisions that meet the requirements of the Act to EPA by November 15, 1993. On November 15, 1993, the Wisconsin Department of Natural Resources (WDNR) submitted to EPA a revised SIP for an enhanced I/M program to cover areas where both the basic and the enhanced requirements apply. The revision included Wisconsin Statutes Sections 110.20 and 144.42 and Chapter 341; Wisconsin Administrative Code Chapters TRANS 131 and NR 485; and the ``Wisconsin Motor Vehicle Inspection Program Request for Proposal for the Establishment and Operation of Motor Vehicle Inspection Program Facilities.'' The State I/M regulations were adopted by WDNR in June 1993 and became effective on July 1, 1993. EPA's summary of the requirements of the Federal I/M regulations as found in 40 CFR part 51.350-51.373 and its analysis of the State submittal are below. A more detailed analysis of the State submittal is contained in a Technical Support Document (TSD) dated June 6, 1994, which is available from the Region 5 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 parts 51.350-51.373. III. EPA's Analysis of Wisconsin's Enhanced I/M Program Applicability--40 CFR 51.350 Section 182(c)(3) of the Act and 40 CFR 51.350(a) require States which contain areas classified as serious or worse ozone nonattainment and containing MSAs with a population of 200,000 or more to implement an enhanced I/M program. As noted above, the State of Wisconsin contains the Milwaukee-Racine MSA in its Milwaukee Severe-17 ozone nonattainment area. In addition, section 182(b)(4) of the Act and 40 CFR part 51.530(a) require States with moderate ozone nonattainment areas containing 1990 Census-defined urbanized areas to implement a basic I/M program. The State of Wisconsin contains the Sheboygan urbanized area where this requirement applies. There are 6 counties in Wisconsin that are required to implement an enhanced I/M program: Kenosha, Milwaukee, Ozaukee, Racine, Washington, and Waukesha Counties. There is one county, Sheboygan County, that is required to implement a basic I/M program. The State has, however, expanded the existing program in the Milwaukee area to cover Sheboygan. The State submittal does contain the legal authority necessary to establish the program boundaries for enhanced I/M. The program boundaries meet the Federal I/M requirements under section 51.350 and are approvable. Wisconsin legislation provides that the I/M program shall apply where an area will not be able to attain the National Ambient Air Quality Standards (NAAQS) without it, and that such coverage can be deleted if demonstrated that the area will attain the NAAQS. This provision allows Wisconsin to add areas to the existing program but does not limit the applicability of the program in the required areas. The Federal I/M regulation requires that the State program shall not terminate until it is no longer necessary. EPA has determined that a SIP which does not terminate prior to the attainment deadline for each applicable area (i.e., 2007 for the Milwaukee severe-17 ozone nonattainment area, and 1996 for the Sheboygan moderate ozone nonattainment area) satisfies this requirement. The Wisconsin program does not contain a termination provision and is therefore approvable. Enhanced I/M Performance Standard--40 CFR 51.351 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. 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 VOCs. The performance standard shall be established using local characteristics, such as vehicle mix and local fuel controls, and model I/M program parameters for the following: network type, start date, test frequency, model year coverage, vehicle type coverage, exhaust emission test type, emission standards, emission control device, evaporative system function checks, stringency, waiver rate, compliance rate and evaluation date. The emission levels achieved by the state's program design shall be calculated using the most current version, at the time of submittal, of the EPA mobile source emission factor model. At the time of the Wisconsin submittal the most current version was MOBILE5a. The Wisconsin submittal includes the following program design parameters: network type--centralized start date--1984 for exhaust testing; 1995 for evaporative testing test frequency--biennial model year coverage--1968+ vehicle type coverage--LDGV, LDGT1, LDGT2, & HDGV exhaust emission test type--IM240 on 1968+ model years emission standards--0.8/20/2.0 gms/mile for HC/CO/NOX to year 2000; 0.6/15/1.5 gms/mile for HC/CO/NOX after year 2000 emission control device visual inspection--none evaporative system function checks--pressure and purge on 1971+ model years stringency (pre-1981 failure rate)--40% waiver rate (pre-1981/1981 and newer)--3% compliance rate--96% evaluation date(s)--2000, 2003, 2006, 2008 The Wisconsin program design parameters meet the Federal I/M regulations and are approvable. The emission levels achieved by the State were modeled using MOBILE5a. The modeling demonstration was performed correctly, used local characteristics and demonstrated that the program design will exceed the minimum enhanced I/M performance standard, expressed in gpm, for VOCs and NOX for each milestone and for the attainment deadline. As noted below, this modeling demonstration does not account for the impact of vehicle exemptions. In addition, this modeling demonstration was not included in the State's November 15, 1993, submittal and has yet to be formally submitted to EPA as a revision to the SIP. In order to receive full approval of its SIP, the State must revise its modeling demonstration to account for exempted vehicles and must formally submit this demonstration in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period which is 30 days following the publication of this notice. Network Type and Program Evaluation--40 CFR 51.353 Enhanced I/M programs shall be operated in a centralized test-only format, unless the State can demonstrate that a decentralized program is equally effective in achieving the enhanced I/M performance standard. The enhanced program shall 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 regulation. 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 emission test of at least 0.1 percent of the vehicles subject to inspection each year, description of the sampling methodology, the data collection and analysis system and the legal authority enabling the evaluation program. The State legislative authority and the State I/M regulations provide for a centralized, test-only network. Wisconsin's centralized, test-only network type is approvable. The submittal does not, however, include provisions for ongoing program evaluation and, as a result, does not meet the Federal I/M regulations. In order to receive final full approval of its program, the State must submit to EPA provisions for ongoing program evaluation satisfying all of the requirements of 40 CFR part 51.353. Specifically, the State must submit schedules for program evaluation and methodologies by which this biennial program evaluation will be carried out, as required by 40 CFR part 51.353. EPA proposes to approve the Wisconsin enhanced I/M SIP if the State submits these provisions in time to allow EPA to place them in the docket for public comment at least 2 weeks prior to the close of the public comment period. Adequate Tools and Resources--40 CFR 51.354 The Federal regulation requires the State to demonstrate that adequate funding of the program is available. A portion of the test fee or a 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 it is demonstrated that the funding can be maintained. Reliance on funding from the State or local General Fund is not acceptable unless doing otherwise would be a violation of the State'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, public education and assistance and other necessary functions. The Wisconsin submittal does not contain a description of funding sources for the I/M program. In order to receive full approval, the State must submit to EPA a description of the method by which the program will be funded. This description must demonstrate that sufficient funds, equipment and personnel have been appropriated to meet the program operation requirements of the I/M rule and must be submitted prior to EPA's final rulemaking on this submittal. EPA proposes to approve the SIP if Wisconsin submits this description in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. 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, shall State how the test frequency is integrated into the enforcement process and shall include the legal authority, regulations, or contract provisions necessary to implement and enforce the test frequency requirement. The program shall be designed to provide convenient service to the motorist by ensuring short waiting times, short driving distances and regular testing hours. The Wisconsin enhanced I/M regulation provides for a biennial test frequency. Based on the performance standard modeling provided by the State, the enhanced I/M program meets the performance standard accounting for the biennial test frequency. On April 13, 1994, The Wisconsin State Legislature enacted legislation which provides the legal authority to implement and enforce the biennial test frequency. This newly adopted legislation has not yet been formally submitted to EPA as a revision to the SIP, however, once submitted, this authority will be acceptable. EPA proposes to approve the Wisconsin SIP if the State formally submits this revised legislation prior to EPA's final action. EPA has included this legislation in the docket for this proposed rulemaking. The Wisconsin I/M Request for Proposal (RFP) provides sufficient evidence that convenient services will be provided to the motorist. The Wisconsin submittal will meet the test frequency and convenience requirements of the Federal I/M regulations and is approvable upon EPA's receipt of the state's newly enacted legislation. 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 part 51.353(a). The Federal I/M regulation requires that the SIP shall 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 may not be registered in the area, and a description of any special exemptions including the percentage and number of vehicles to be impacted by the exemption. The Wisconsin enhanced I/M legislation, enacted April 13, 1994, requires coverage of all 1968 and newer light duty vehicles and trucks up to 14,000 pounds GVWR, which are registered or required to be registered in the I/M program area. The Wisconsin legislation and the state's I/M regulations provide the legal authority to implement and enforce the vehicle coverage. This level of coverage is approvable because it provides the necessary emission reductions. The State RFP also describes general requirements related to vehicle coverage. The State submittal does not contain estimates of the number of registered or unregistered vehicles in the area or methods for identifying subject vehicles. These items will be described in more detail in the states final, signed I/M contract, which must be submitted to EPA prior to EPA's final rulemaking, in order to receive full approval on its submittal. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. The state's November 15, 1993, SIP submittal does not adequately address fleet testing requirements. Existing regulations allow for the self testing and repair of fleets and directly contradict the requirements of the final I/M rule. The State is moving forward to amend its TRANS 131 rule to establish detailed provisions for the testing of fleets in accordance with EPA's final rule. In its submittal, the State indicates that these rule changes cannot be completed prior to EPA's final action. EPA proposes to conditionally approve this portion of the state's submittal if the State commits prior to final rulemaking to completing these amendments within one year of EPA's final conditional approval. The state's plan for testing fleet vehicles must meet the requirements of the Federal I/M regulation. The State regulation provides for limited special exemptions. In its submittal the State did not provide a description of the exemptions' impact on the subject fleet. In addition, the modeling demonstration submitted by the State does not account for these exemptions in the emission reduction analysis. The State must describe the extent of the exemptions impact in accordance with 40 CFR part 51.356 in order for EPA to fully approve the state's submittal. EPA proposes to approve the SIP if the State submits, in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period, a description that indicates that the performance standard will not be adversely affected. 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 part 51.357 and in the EPA document entitled ``High-Tech I/M Test Procedures, Emission Standards, Quality Control Requirements, and Equipment Specifications'', EPA-AA-EPSD-IM-93-1, dated July 1993. The State I/M RFP includes a general provision for loaded tailpipe emission, evaporative system purge, and evaporative system pressure testing. Detailed descriptions of the test procedures and standards will be contained in the state's final, signed I/M contract. After reviewing the state's RFP, EPA believes that these test procedures and standards will conform to EPA approved test procedures and will be approvable. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.357 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. In addition, the State is currently in the process of amending its rule NR 485 to establish a series of increasingly stringent emission limits (cutpoint schedule) for VOC and NOX to correspond to those used in the state's modeling demonstration. In its submittal, the State indicates that these rule changes cannot be completed prior to EPA's final action. EPA proposes to conditionally approve this portion of the state's submittal if the State submits a commitment to EPA prior to final rulemaking committing to complete these amendments within one year of EPA's final conditional approval. The State is also in the process of applying for an exemption from NOX control requirements under section 182(f) of the Act. The state's contract and regulations should contain provisions for establishing a NOX testing requirement, however, these provisions may allow for establishing the NOX cutpoint in accordance with EPA's action on the section 182(f) petition. If EPA approves this petition for exemption, the I/M rule does not require NOX emission reductions from the program but the program must be designed to offset NOX increases resulting from HC and CO failures pursuant to 40 CFR part 51.351(d). EPA proposes to approve this portion of the SIP if the State submits the final contract containing NOX provisions consistent with this discussion in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. The State RFP also contains provisions requiring 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. However, detailed descriptions of these procedures will be contained in the state's final, signed I/M contract. After reviewing the state's RFP, EPA believes that these test procedures and standards will conform to EPA approved test procedures and will be approvable. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.357 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. 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 the State SIP submittal 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. The State RFP contains general specifications for test equipment to be used in the program. The specifications require the use of computerized test systems. The specifications will be further developed in the final I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.358 to EPA prior to final rulemaking. The contract must include performance features and functional characteristics of the computerized test systems which meet the Federal I/M regulations. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. Quality Control--40 CFR 51.359 Quality control measures shall insure that emission measurement equipment is calibrated and maintained properly, and that inspection, calibration records, and control charts are accurately created, recorded and maintained. The State RFP contains general provisions for the establishment of quality control measures for the emission measurement equipment, record keeping requirements, and measures to maintain the security of all documents used to establish compliance with the inspection requirements. These measures and practices will be further developed in the state's final I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.359 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. Waivers and Compliance Via Diagnostic Inspection--40 CFR 51.360 The Federal I/M regulation 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 applicable 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. Repairs for 1980 and newer model year vehicles must be performed by a recognized repair technician. The Federal regulation allows for compliance via a diagnostic inspection after failing a retest on emissions and requires quality control of waiver issuance. The SIP must set a maximum waiver rate and must describe corrective action that must be taken if the waiver rate exceeds that committed to in the SIP. The legislative authority and State regulation provides the necessary authority to issue waivers, set and adjust cost limits, and administer and enforce the waiver system. The Wisconsin I/M regulation sets a $450 cost limit and allows for an annual adjustment of the cost limit to reflect the change in the CPI as compared to the CPI in 1989 for the 6 county Milwaukee nonattainment area and a $200 cost limit for 1981 and newer models and a $75 cost limit for vehicles older than model year 1981 in Sheboygan county. Although amended legislative authority requires actual expenditure of funds to qualify towards the cost limit, existing regulations still allow estimates of repair costs to qualify. The provisions of the Wisconsin legislative authority override the previous administrative rule in this situation. In addition, Wisconsin is amending its regulations to correct this contradiction. EPA proposes to conditionally approve the SIP based on Wisconsin's commitment to adopt and submit these regulatory amendments within one year of final action. The State must submit this commitment to EPA prior to final action in order to receive conditional approval. The regulation and RFP include provisions which address waiver criteria and procedures, including cost limits, tampering and warranty related repairs, quality control and administration. These provisions will be further developed in the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.360 to EPA prior to final rulemaking. The contract must require repairs for vehicles to be performed by a recognized or certified repair technician. The contract may allow for compliance via diagnostic inspection provided the policies and procedures outlined in the submittal meet Federal I/M regulations. The State regulation allows for time extensions. The contract must specify the criteria for allowing time extensions and for tracking extensions. The State has set a maximum waiver rate of 3 percent for both pre- 1981 and for 1981 and later vehicles. While the State has a good history of maintaining the program's waiver rate, EPA is concerned that the State may have a problem maintaining the 3 percent waiver rate given the lower expenditure waiver limit in Sheboygan county (i.e., $450 versus $200). Therefore, in order to receive full approval the State must describe corrective actions to be taken if the waiver rate exceeds 3 percent. This waiver rate has been used in the performance standard modeling demonstration and is approvable. However, in its SIP submittal, the State did not include a formal commitment to the waiver and compliance rates used in the modeling demonstration. EPA proposes to approve the SIP if Wisconsin submits the contract, description of corrective actions, and appropriate commitments in time to allow EPA to place them in the docket 2 weeks prior to the close of the public comment period. 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. Registration denial enforcement consists of rejecting an application for initial registration or reregistration of a used vehicle unless the vehicle has complied with the I/M requirement prior to the granting of the application. The SIP shall provide information concerning the enforcement process, legal authority to implement and enforce the program, a commitment to a compliance rate to be used for modeling purposes and to be maintained in practice. Wisconsin's legislative authority and I/M regulations provide the legal authority to implement a registration denial system. Wisconsin has set a compliance rate of 96 percent, which was used in the performance standard modeling demonstration. However, in its SIP submittal, the State did not include a formal commitment to this compliance rate. The submittal includes detailed information concerning the registration denial enforcement process which meets the Federal I/M regulation requirements and is approvable. The State has not submitted a detailed penalty schedule including a description of mandatory, meaningful fines for the program. The State is in the process of amending its TRANS 131 rule to establish a more thorough penalty schedule. In its submittal, the State indicates that these rule changes cannot be completed prior to EPA's final action. EPA proposes to conditionally approve this portion of the state's submittal if the State submits a commitment to EPA prior to final rulemaking committing to completing these amendments within one year of EPA's final conditional approval. The state's penalty schedule must meet the requirements of the Federal I/M regulation. 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. The Wisconsin RFP contains general provisions for quality control of the enforcement program and includes the establishment of an information management system. These provisions will be further developed in the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.362 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. 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. The State must submit a description of the quality assurance program, including written procedure manuals on the above discussed items, as part of the SIP. The Wisconsin RFP includes general provisions for a quality assurance program. The final, signed I/M contract will provide specific details and procedures for inspections, records, equipment audits, and formal training for all State enforcement officials will be specified by the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.360 to EPA prior to final rulemaking. Detailed procedures for performing overt and covert audits are being developed separately from the final, signed I/M contract. The State must submit a description of these procedures to EPA in order to receive full approval of its submittal. EPA proposes to approve the SIP if Wisconsin submits the contract and description of audit procedures in time to allow EPA to place them in the docket 2 weeks prior to the close of the public comment period. Enforcement Against Contractors, Stations and Inspectors--40 CFR 51.364 Enforcement against licensed stations or 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. 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, the resources to be allocated to this function, and the source of those funds. The Wisconsin submittal includes the legal authority to establish and impose penalties against stations, contractors and inspectors. The State I/M regulation and legislation includes general penalty provisions for stations, contractors and inspectors. Specific penalty schedules will be detailed in the final signed, I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.364 to EPA prior to final rulemaking. In addition, the submittal does not include a description of administrative and judicial procedures relevant to the enforcement process which meets Federal I/M regulations. The State must submit this documentation to EPA in order for the submittal to be fully approved. EPA proposes to approve the SIP if Wisconsin submits the contract and description of administrative and judicial procedures in time to allow EPA to place them in the docket 2 weeks prior to the close of the public comment period. Data Collection--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 part 51.359. The RFP contains provisions regarding the collection of data on each individual test conducted and generally describes the type of data to be collected. These provisions will be further developed in the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.365 to EPA prior to final rulemaking. The submittal also commits to gather and report the results of the quality control checks required under 40 CFR part 51.359 and will be approvable upon EPA's receipt of the final, signed I/M contract. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. Data Analysis and Reporting--40 CFR 51.366 Data analysis and reporting are required to allow for monitoring an evaluation of the program by the State and EPA. The Federal I/M regulation requires annual reports to be submitted that provide information and statistics and 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 of January to December of the previous year. A biennial report shall be submitted to EPA that addresses changes in program design, regulations, legal authority, program procedures, any weaknesses in the program found during the previous two-year period and how these problems will be or were corrected. The RFP provides general provisions for the analysis and reporting of data for the testing program, quality assurance program, quality control program and the enforcement program. These provisions will be further developed in the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR 51.364 to EPA prior to final rulemaking. The State must also commit to submit annual reports on these programs to EPA by July of the subsequent year. A commitment to submit a biennial report to EPA, which addresses reporting requirements set forth in 40 CFR 51.366(e), must also be submitted to EPA in order to receive full approval. EPA proposes to approve the SIP if Wisconsin submits the contract, a commitment to submit annual reports and a biennial report in time to allow EPA to place them in the docket 2 weeks prior to the close of the public comment period. Inspector Training and Licensing or Certification--40 CFR 51.376 The Federal I/M regulation requires all inspectors to be formally trained and licensed or certified to perform inspections. The RFP contains general provisions regarding requirements for inspectors' formal training, certification and licensing. The signed contract will include a description of the training program, the written and hands-on tests, and the licensing, certification processes. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.376 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. Public Information and Consumer Protection--40 CFR 51.368 The Federal I/M regulation requires the SIP to include public information and consumer protection programs. The RFP includes a public information program, which educates the public on I/M, State and Federal regulations, air quality, the contribution of motor vehicles to the air pollution problem, and other items as described in the Federal rule. The consumer protection program, which includes provisions for a challenge mechanism, protection of whistle blowers and assistance to motorists in obtaining warranty covered repairs, will be further developed in the final contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.364 to EPA prior to final rulemaking. EPA proposes to approve the SIP if Wisconsin submits the contract in time to allow EPA to place them in the docket 2 weeks prior to the close of the public comment period. 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 State shall provide the repair industry with information and assistance related to vehicle inspection diagnosis and repair. 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. The RFP includes general provisions for the implementation of a technical assistance program, which includes a hot line service to assist repair technicians and a method of regularly informing the repair facilities of changes in the program, training courses, and common repair problems. A repair facility performance monitoring program is also included in the RFP. This program provides the motorist whose vehicle fails the test a summary of local repair facilities' performances, and requires the submittal of a completed repair form at the time of retest. The program also provides feedback to each repair facility on its repair performance. These provisions will be further developed in the final, signed I/M contract. In order to receive full approval, the State must submit its final, signed contract addressing the requirements of 40 CFR part 51.369 to EPA prior to final rulemaking. The State must also submit a description of available repair technician training resources. EPA proposes to approve the SIP if Wisconsin submits the contract and description of training resources in time to allow EPA to place it in the docket 2 weeks prior to the close of the public comment period. Compliance With Recall Notices--40 CFR 51.370 The Federal regulation requires the states to establish methods to ensure that vehicles that are subject to enhanced I/M and are included in a emission related recall receive the required repairs prior to completing the emission test or renewing the vehicle registration. The Wisconsin legislation provides the legal authority to require owners to comply with emission related recalls before completing the emission test. Specific procedures to be used to incorporate national database recall information into the State inspection database and quality control methods to insure that recall repairs are properly documented and tracked will be provided in the final, signed I/M contract, and will also be specified through amendments to the state's TRANS 131 rule. The submittal does not include a commitment to submit an annual report to EPA that includes the information required in 40 CFR part 51.370(c). In its submittal, the State indicates that these rule changes cannot be completed prior to EPA's final action. EPA proposes to conditionally approve this portion of the state's submittal if the State submits a commitment to EPA prior to final rulemaking committing to completing these amendments and submitting annual reports within one year of EPA's final conditional approval. 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 percent 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 emission test and are found to be high emitters as a result of a on-road test shall be required to pass an out-of-cycle test. Legal authority to implement the on-road testing program and enforce off-cycle inspection and repair requirements is contained in the State legislation. The SIP submittal requires the use of RSD and roadside pullovers to test at least 0.5 percent of the subject fleet per year in the I/M program area. A description of the program which includes test limits and criteria, resource allocations, and methods of collecting, analyzing and reporting the results of the testing will be detailed in the final I/M contract and amendments to the state's TRANS 131 rule. In its submittal, the State indicates that these rule changes cannot be completed prior to EPA's final action. EPA proposes to conditionally approve this portion of the state's submittal if the State submits a commitment to EPA prior to final rulemaking committing to completing these amendments within one year of EPA's final conditional approval. State Implementation Plan Submissions/Implementation Deadlines--40 CFR 51.372-373 The Federal regulation requires enhanced I/M programs to be implemented by January 1, 1995 except for: (1) Existing test-and-repair programs, which may test 30 percent of the subject fleet in the test- only system during 1995 and test all subject vehicles in the test-only system beginning January 1, 1996 (during the phase-in period, existing requirements may continue to apply for the test-and-repair portion of the program until it is phased out by January 1, 1996) or (2) Areas starting new test-only programs and those with existing test-only programs may phase in the new test procedures between January 1, 1995 and January 1, 1996; however, all other program requirements must be fully implemented by January 1, 1995. The Wisconsin submittal included final State I/M regulations, preliminary legislative authority to implement the program, final specifications, a final RFP, procedural documents, and a discussion on each of the required program design elements. The submittal states that all inspectors and stations will be certified, that mandatory testing has already started, and that the start date for implementation will be July 3, 1995. The submittal also includes a commitment to include onboard diagnostic checks in the I/M program within 2 years after promulgation of onboard diagnostic check regulations for I/M programs. As noted in this proposed rulemaking, the State must timely submit its final, signed I/M contract, most recent changes to its I/M legislation enacted on April 13, 1994, final modeling demonstration, narrative descriptions of certain program elements, commitments to minimum compliance and enforcement related activity levels, and final rule changes or appropriate commitments prior to EPA's final rulemaking in order to receive final approval and conditional approval of its I/M submittal. EPA's review of the material indicates that, subject to the conditions and contingencies noted above, the State has adopted an enhanced I/M program in accordance with the requirements of the Act. EPA is proposing to approve and conditionally approve the Wisconsin SIP revision for an enhanced I/M program, which was submitted on November 15, 1993, contingent on the timely receipt of the materials noted above from the State. EPA is soliciting public comments on the issues discussed in this notice and the additional material to be placed in the docket during the public comment period, or on other relevant matters. These comments will be considered before taking final action. Interested parties may participate in the Federal rulemaking procedure by submitting written comments to the EPA Regional office listed in the ADDRESSES section of this notice. Proposed Action EPA is proposing to approve portions and conditionally approve other portions of this revision to the Wisconsin SIP for an enhanced I/ M program. In the alternative, if Wisconsin fails to timely submit the materials discussed above, or if such materials do not meet the requirements of the Federal I/M rule, EPA proposes to disapprove the SIP or to conditionally approve these portions of the plan if the State submits the appropriate commitment(s) to remedy any deficiencies within one year of final conditional approval. I. Basis for Conditional Approval The EPA believes conditional approval is appropriate in this case because the State has developed final, fully adopted rules for the enhanced I/M program and needs only to amend these rules to address a number of enhanced I/M program requirements. As a condition of the U.S. EPA's proposed conditional approval, the State must submit final, fully adopted rules to EPA no later than one year after EPA's final conditional approval. II. Statement of Approvability Under the authority of the Governor, the Wisconsin Department of Natural Resources submitted a SIP revision to satisfy the requirements of the I/M regulation to the EPA on November 15, 1993. The Agency has reviewed this submittal and is proposing to approve portions and proposing to conditionally approve other portions of it pursuant to Sections 110(k) of the Act, on the condition that the portions of the I/M program noted above are adopted and/or submitted on the schedules noted in this proposed rulemaking. If the State fails to timely submit the required regulations and other material or commit to do so within one year of EPA's final conditional approval, EPA proposes in the alternative to disapprove the SIP as failing to comply with section 110 and Part D. If the EPA takes final conditional approval on the commitment, the State must meet its commitment to adopt and submit the final rule amendments within one year of the conditional approval. Once the EPA has conditionally approved this committal, if the State fails to adopt or submit the required rules to EPA, final approval will become a disapproval. EPA will notify the State by letter to this effect. Once the SIP has been disapproved, these commitments will no longer be a part of the approved nonattainment area SIPs. The EPA subsequently will publish a notice to this effect in the notice section of the Federal Register indicating that the commitment or commitments have been disapproved and removed from the SIP. If the State adopts and submits the final rule amendments to the EPA within the applicable time frame, the conditionally approved commitments will remain part of the SIP until the EPA takes final action approving or disapproving the new submittal. If the EPA approves the subsequent submittal, those newly approved rules will become a part of the SIP. If after considering comments on the proposal, the EPA issues a final disapproval or if the conditional approval portions are converted to a disapproval, the sanctions clock under section 179(a) will begin. This clock will begin on the effective date of the final disapproval or at the time the EPA notifies the State by letter that a conditional approval has been converted to a disapproval. If the State does not submit and the EPA does not approve the rule on which the disapproval was based within 18 months of the disapproval, the EPA must impose one of the sanctions under section 179(b)--highway funding restrictions or the offset sanction. In addition, the final disapproval starts the 24 month clock for the imposition of a section 110(c) Federal Implementation Plan. Finally, under section 110(m) the EPA has discretionary authority to impose sanctions at any time after a final disapproval. Procedural Background The OMB has exempted this action rule from Executive Order 12866 review. 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 Act do not create any new requirements, but simply approve requirements that the State is already imposing. Therefore, because the Federal SIP approval does not impose any new requirements, I certify 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 regulatory 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. E.P.A., 427 U.S. 246, 256-66 (S. Ct. 1976); 42 U.S.C. 7410(a)(2).
