I/M PROGRAM
§ 177.51. Program requirements.
(a) Network type. Testing shall be performed through a decentralized system of privately owned and operated, Department-certified facilities.
(b) Test-and-repair. Emission inspection stations may conduct both testing and repairing of subject vehicles.
(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. Current model year vehicles and vehicles driven less than 5,000 miles per year are exempt from this requirement.
(f) Exhaust emission test types. The following types of tests will be administered to the appropriate model years and fuel types, subject to subsection (c)(2):
(1) Prior to the date established in accordance with § 177.22 (relating to commencement of inspections), subject vehicles registered in counties in the Philadelphia Region will be required to undergo the following tests:
