Title 67--TRANSPORTATION

DEPARTMENT OF TRANSPORTATION

[67 PA. CODE CH. 177]

Emissions Inspection Program

[33 Pa.B. 5706]

   The Department of Transportation (Department), Bureau of Motor Vehicles (Bureau) amends Chapter 177 (relating to emission inspection program) by adding provisions for vehicle emission inspection and maintenance (I/M) testing using the onboard diagnostic (OBD) systems in model year (MY) 1996 and newer vehicles.

   The I/M program, implemented under 75 Pa.C.S. §§ 4103, 4531, 4701, 4706, 4707, 4710, 6103 and 9104, is required by the Federal Clean Air Act (Clean Air Act), as amended by Pub. L. No. 101-52, 104 Stat. 2399-2712 (42 U.S.C.A. §§ 7401--26718) and Pub. L. No. 104-59, 109 Stat. 568 (1995), known as the National Highway System Designation Act of 1995. Implementation of emission testing using vehicle OBD systems is required by the Clean Air Act and recent amendments to 40 CFR Parts 51 and 85 (relating to regulations for preparation, adoption and submittal of implementation plans; and control of air pollution from mobile sources).

   Proposed rulemaking is omitted under 75 Pa.C.S. § 4706 (relating to prohibition on expenditures for emission inspection program), which exempts the regulations from the proposed rulemaking provisions of the act of July 31, 1968 (P. L. 769, No. 240) (45 P. S. §§ 1201 and 1202), known as the Commonwealth Documents Law, the Regulatory Review Act (71 P. S. §§ 745.1--745.12) and 75 Pa.C.S. § 4710 (relating to Vehicle Emission System Inspection Program Advisory Committee), which provides for initial submission of final regulations regarding the vehicle emission I/M program to the Office of Attorney General for review as to form and legality and thereafter to the Independent Regulatory Review Commission (IRRC) and the House and Senate Transportation Committees in accordance with the Regulatory Review Act.

Purpose of Chapter 177

   Chapter 177 implements an emission I/M program as required by the Clean Air Act and regulations promulgated thereunder, 40 CFR Parts 51 and 85.

Purpose of the Final-Omitted Rulemaking

   The final-omitted rulemaking incorporates OBD-I/M testing of MY 1996 or newer vehicles into the I/M program in this Commonwealth, in compliance with the Clean Air Act and amendments to 40 CFR Parts 51 and 85 (relating to requirements for preparation, adoption and submittal of implementation plans; and control of air pollution from mobile sources) which require states to implement OBD testing. The final-omitted rulemaking also implements gas cap testing and visual antitampering inspection in selected counties.

   The engines in vehicles MY 1996 and newer are largely electronically controlled. Sensors and actuators sense the operation of specific components (for example, oxygen sensors) and actuate others (for example, fuel injectors) to maintain optimal engine performance and control. An onboard computer controls all of these systems. With proper software, the onboard computer is capable of monitoring all of the sensors and actuators to determine whether they are working as intended. It can detect a malfunction or deterioration of the various sensors and actuators, usually well before the driver becomes aware of the problem through a loss in vehicle performance or drivability. The sensors and actuators, along with the diagnostic software in the onboard computer, make up what is called the OBD system.

   Many component failures that impact emissions can be electrical or even chemical in nature. The OBD system is intended to detect problems that may not be noticeable upon visual inspection. When the OBD system determines that a problem exists, a corresponding ''diagnostic trouble code'' is stored in the computer's memory. When the vehicle is taken to a service center or repair shop, a service technician can retrieve the stored diagnostic trouble codes from the computer memory of the vehicle using newly developed diagnostic tools. Since the diagnostic trouble codes will specifically identify the problem, the service technician can more quickly and accurately make the proper repair.

   The Clean Air Act (42 U.S.C.A. §§ 7401--7671q) as amended in 1990 required the Environmental Protection Agency (EPA) to set requirements for states to follow in designing and operating vehicle I/M programs. In addition to distinguishing between basic and enhanced I/M programs, the requirements also clarify how states can meet other minimum design requirements set by the Clean Air Act. One requirement applicable to both basic and enhanced I/M programs includes OBD system checks as part of the required periodic inspection.

   On November 5, 1992, the EPA published regulations meeting most of the requirements of the Clean Air Act. At the time the regulations were promulgated, however, Federal OBD certification standards had not yet been developed and published. To address the Clean Air Act's OBD-I/M requirement, the EPA reserved sections in the regulations with the understanding that the reserved sections would be amended on a future date. Although the Federal requirement to incorporate OBD into new vehicles began with MY 1994, manufacturers were allowed to request waivers on vehicles for MY 1994-95. Full compliance was not required on all light-duty cars and trucks sold in the United States until MY 1996. On August 6, 1996, the EPA published amendments to the 1992 I/M regulations establishing OBD-I/M performance standards. The 1996 amendments also established data collection, analysis and summary reporting requirements for the OBD-I/M testing element; established OBD test equipment requirements and the OBD test result reporting format; and identified those conditions that would result in an OBD-I/M pass, failure or rejection. Lastly, the August 6, 1996, amendments revised 40 CFR Part 85, Subpart W (relating to emission control systems performance warranty short test) to establish OBD-I/M as an official performance warranty short test under section 207(b) of the Clean Air Act (42 U.S.C.A. § 7541(b)).

   At the time the original OBD-I/M requirements were established, it was not practical to evaluate the real world, in-use performance of OBD because the vehicles in question were still too new and the number of vehicles in need of repair was too few to make pilot testing worthwhile. In 1998, the EPA further amended its OBD-I/M requirements to provide that state I/M programs begin OBD testing by January 1, 2001. In April 2001, the EPA amended its OBD-I/M regulations to: (1) provide states several options for extending the current deadline for mandatory implementation of OBD-I/M inspection beyond January 1, 2001; (2) clarify states' options regarding the integration of OBD-I/M checks into existing I/M programs; (3) revise and simplify the current list of diagnostic trouble codes that constitute the OBD-I/M failure criteria to include any code that leads the dashboard malfunction indicator light to illuminate; and (4) provide for exemptions from specific readiness code rejection criteria on OBD-equipped vehicles based upon vehicle MY.

   In addition to the inclusion of OBD-I/M testing in the I/M program, these amendments correct some organizational and typographical deficiencies in the existing regulations.

Significant Provisions of the Final-Omitted Rulemaking

   § 177.3.  Definitions. Since 1999, the Commonwealth has not conducted a basic emissions inspection program, conducting only enhanced programs in Bucks, Chester, Delaware, Montgomery and Philadelphia Counties (Philadelphia region) and in Allegheny, Beaver, Washington and Westmoreland Counties (Pittsburgh region). Going forward, the inclusion of OBD-I/M testing will be incorporated into the enhanced program and expanded to other counties and regions in this Commonwealth. Consequently, the basic/enhanced distinction has no significance for the emission I/M program in this Commonwealth and the definitions have been eliminated. References to the basic program and use of the word ''enhanced'' as a modifier throughout the regulation have been eliminated in the final-omitted rulemaking.

   In addition, since air quality attainment status is determined on a regional basis, it is more appropriate to discuss elements of the program in terms of regions. The definition of ''I/M area'' has been replaced with ''I/M region.'' Insofar as air quality considerations may require, the Secretary may initiate emission inspections in a single county as well. Counties and regions in which an I/M program is currently being administered or envisioned are included in the definition of ''I/M region.''

   Also included are definitions for new terms and acronyms related to OBD technology. Definitions are provided for ''DTC--diagnostic trouble code,'' ''MIL--malfunction indicator light,'' ''OBD--onboard diagnostics,'' ''OBD data link connector (DLC),'' ''readiness code'' and ''scanner or scan tool.''

   § 177.22.  Commencement of inspections. The Department plans to begin the implementation of OBD-I/M testing on or before the close of the 2003 calendar year, as testing and recording equipment compatible with the Department's vehicle inspection information database is developed and marketed to inspection stations. This section provides that the Secretary will give notice by publication in the Pennsylvania Bulletin of effective dates for the transition of the existing emission I/M inspection programs in the Philadelphia and Pittsburgh regions to programs which include OBD-I/M testing and to initiate OBD-I/M testing programs in other counties and regions as appropriate. The notice will provide motorists in those counties or regions with 60 days notice of the transition or initiation of the program.

   This section also recognizes that, over time, the number of pre-1996 vehicles (which, generally, were not manufactured with the OBD technology) required to receive actual tailpipe testing and analysis of emitted gasses under the final-omitted rulemaking will gradually decrease and their contribution to air pollution in the region in which they are registered will diminish. Consistent with EPA guidelines, therefore, this section provides that the Secretary can reduce the test cycle or eliminate the emission testing of these vehicles altogether, provided that emissions in the region are at or below State implementation plan levels and the I/M performance standards for the region are being met. Notably, this section also makes clear, however, that the requirements for annual safety inspections of all vehicles are not affected by any change in the emission I/M program.

   § 177.51.  Program requirements. This section is amended to include the provisions for OBD-I/M testing of vehicles of MY 1996 and newer once an effective date for implementation of the program in a given county or region is established by the Secretary. Consistent with EPA regulations and guidelines, MY 1996 and newer vehicles will receive both an OBD-I/M check and the existing fuel filler cap (gas cap) test. This section is amended to provide that as a vehicle MY becomes 25 years of age and fewer vehicles of that MY are driven, vehicles of that MY will be required to undergo only the gas cap test and a visual inspection.

   In regions of this Commonwealth where the I/M program has already been established and some vehicles are subject to acceleration simulation mode or dynamometer testing, the capability to perform the OBD-I/M check will be required for existing participating emission inspection stations. New inspection stations capable of performing only the OBD-I/M check will not be certified in these regions for 2 years following the promulgation of this rulemaking to ensure that motorists in those regions will be able to receive an emission inspection at any certified station, regardless of the kind of test that is required for their vehicle. It may reasonably be anticipated that after the OBD-I/M check has been in place for 2 years, the population of pre-MY 1996 vehicles will have diminished in those regions and motorist awareness of the differences in the emission inspection tests will have increased so that certification of OBD-I/M check only stations will not result in significant motorist confusion or dissatisfaction.

   § 177.106 (now § 177.275).  Repair technician training and certification. This section is amended to include language requiring training in OBD technology and the OBD testing requirements being implemented. It incorporates, but relocates to § 177.275, the existing language requiring completion of a course relating to the Commonwealth's emission I/M program and adds a requirement of completion of additional training specifically related to OBD-I/M technology and repair.

   § 177.202a.  OBD-I/M check equipment. This new section describes the performance features required of equipment used to perform the OBD-I/M check. Reference is made to specifications developed by the Department and its consultants ensuring that the data retrieved in the performance of the OBD-I/M check can be communicated to the Department's vehicle inspection information database.

   § 177.203.  Test procedures. This section is amended to delete provisions relating to a ''basic'' I/M program and eliminate the use of ''enhanced'' as a modifier. Procedures for establishing a vehicle's ''readiness'' for the OBD-I/M check as well as for conducting the test are added to this section. Procedures currently found only in Appendix B for performance of the gas cap test and procedures for performance of the visual inspection in § 177.204 (relating to basis for failure) have been moved to this section, a more appropriate location.

   § 177.204.  Basis for failure. This section includes criteria for failure of all the I/M program tests, not simply standards for permissible levels of emitted gasses. Criteria for failure of the OBD-I/M check are also included and track the requirements and recommendation of the EPA.

   § 177.252.  Emission inspection report. The amendments to this section eliminate provisions regarding the ''basic'' I/M program no longer conducted in this Commonwealth. Requirements for the report to be given the vehicle owner or operator under § 177.252 under the existing program are retained. Requirements of the report to be given to vehicle owners or operators on which the OBD-I/M check is performed have been added. The OBD-I/M check report details the readiness results and diagnostic trouble codes revealed in the test, as well as providing information on any applicable recall for the vehicle and the availability of warranty coverage.

   § 177.406.  Equipment. The amendments to this section include OBD scanners or scan tools in the list of equipment required at an official emission inspection station. The amendments also deletes reference to specifications for equipment at ''basic'' I/M stations.

   § 177.408.  Certified emission inspectors. This section is amended to delete references to a ''basic'' and ''enhanced'' I/M program. The amendments also include the training required for certification as an emission inspector for the OBD-I/M check.

   § 177.501.  Equipment approval procedures. This section is amended to delete references to a ''basic'' and ''enhanced'' I/M program and to remove provisions specific to the ''basic'' program no longer conducted in this Commonwealth. The amendments also delete the provisions for ''interim'' approval relevant only during the start-up period of the I/M program. The amendments also include new requirements to be met for approval of equipment to be used in the OBD-I/M check.

Persons and Entities Affected by the Final-Omitted Rulemaking

   The final-omitted rulemaking will affect the owners and operators of vehicles registered in this Commonwealth as well as individuals in the business of vehicle inspection and vehicle repair in the affected counties.

Fiscal Impact

   The final-omitted rulemaking will require the purchase of new equipment by existing emission inspection stations and by new stations in the areas in which an I/M program is being initiated. The cost will be recouped through the fees charged to vehicle owners for inspections. In some regions, the final-omitted rulemaking may nevertheless result in savings to vehicle owners in the form of lower cost of emission inspection with introduction of the simpler OBD-I/M check. In counties in which the final-omitted rulemaking initiates an I/M program, vehicle owners will experience increased costs for the emission inspection. These costs or savings to the general motoring public are not, however, readily measurable. Costs of the I/M tests are market driven and are not regulated by the Department. Station owners vary in the fee charged for I/M testing and vehicle owners have the opportunity to choose a station with a fee acceptable to them. The Department cannot, however, measure with any precision what costs and savings may result in the marketplace.

Regulatory Review

   Under 75 Pa.C.S. § 4710(e), the Department submitted a copy of the final-omitted rulemaking to the Office of Attorney General on August 12, 2003. The final-omitted rulemaking was approved as to form and legality by the Office of Attorney General on September 10, 2003. The Department submitted a copy of this final-omitted rulemaking on September 11, 2003, to IRRC and to the Chairpersons of the House and Senate Transportation Committees for review consistent with section 5 of the Regulatory Review Act (71 P. S. § 745.5). On October 10, 2003, the final-omitted rulemaking was tolled and resubmitted to IRRC and the Committees. In accordance with section 5(c) of the Regulatory Review Act, this final-omitted rulemaking was deemed approved by the Committees on October 30, 2003, and was approved by IRRC on November 6, 2003.

   In addition to the final-omitted rulemaking, the Committees were provided with a copy of a detailed Regulatory Analysis Form prepared by the Department. A copy of this material is available to the public upon request.

   In preparing the final-omitted rulemaking, the Department has considered the comments received from the EPA, the public and individuals in the business of vehicle inspection and repair.

Sunset Provisions

   The Department is not establishing a sunset date for this final-omitted rulemaking since the final-omitted rulemaking is necessary to comply with requirements of Federal laws regarding control of vehicle emissions.

Contact Person

I/M PROGRAM

§ 177.51.  Program requirements.

*      *      *      *      *

   (c)  Inspection. Subject vehicles shall be emission inspected annually in coordination with a safety inspection according to procedures established by the Bureau, subject to paragraphs (1)--(3). A safety inspection certificate for a vehicle subject to an emission inspection may not be affixed to the vehicle until the subject vehicle has passed an emission inspection or received an exemption or a waiver as provided in § 177.281 (relating to issuance of waiver). The term ''safety inspection certificate'' as used in this subsection does not include temporary inspection approval indicators as defined in § 175.2 (relating to definitions). Safety inspection stations are not required to conduct emission inspections to maintain certification as safety inspection stations.

   (1)  When the Secretary certifies, by publication of a notice in the Pennsylvania Bulletin, that the number of subject pre-MY 1996 vehicles constitutes less than 40% of the total subject vehicles registered in an I/M county or region, subject pre-MY 1996 vehicles in that I/M county or region shall be inspected biennially in coordination with an annual safety inspection, provided that emissions in that I/M county or region are at or below levels which are in compliance with the State Implementation Plan, conformity requirements under the Clean Air Act, and the I/M performance standard.

   (2)  At such time as the Secretary certifies, by publication of a notice in the Pennsylvania Bulletin, that the number of subject pre-MY 1996 vehicles constitutes less than 20% of the total subject vehicles registered in an I/M county or region, pre-MY 1996 vehicles shall no longer be subject to the I/M program, provided that emissions in that I/M county or region are at or below levels which are in compliance with the State Implementation Plan, conformity requirements under the Clean Air Act, and the I/M performance standard.

   (3)  Nothing in this section relieves any vehicle from the requirements for annual safety inspections under Chapter 175 (relating to vehicle equipment and inspection).

   (d)  I/M counties or regions covered. The Department will establish counties or regions within this Commonwealth which are subject to an emission inspection by certification of the Secretary of the need to comply with Federal law and will publish the certification as a notice in the Pennsylvania Bulletin listing the I/M counties or regions.

   (e)  Model year coverage. Subject gasoline-powered motor vehicles with a model year of 1975 and newer with a GVWR of 9,000 pounds or less and registered in an I/M county or region are subject to an emission inspection.
