19VAC30-70-310. Air pollution control system or device.

A. No motor vehicle manufactured for the model year 1973 or for subsequent model years shall be operated on the highways of this Commonwealth unless it is equipped with an air pollution control system or device, or combination of such systems or devices installed in accordance with federal laws and regulations.

B. The provisions of this section shall not prohibit or prevent shop adjustments or replacements of equipment for maintenance or repair or the conversion of engines to low polluting fuels, such as, but not limited to, natural gas or propane, so long as such action does not degrade in any manner or to any degree the anti-pollution capabilities of the vehicle power system.

C. Inspect for and reject if:

1. The air pollution control system or device on motor vehicles manufactured for the model year 1973 or for subsequent model years has been removed or otherwise rendered inoperable. The conversion of an engine to utilize low polluting fuels such as natural gas or propane may result in the removal of some part of the pollution control system; however, if the engine is converted to utilize both low polluting fuels and/or gasoline no part of the pollution control system or device can be removed or otherwise rendered inoperable.

2. Any of the essential parts of the pollution control system or devices on vehicles manufactured for the model year 1973 or for subsequent model years have been removed, rendered inoperable or disconnected. This includes any belt, valve, pump, hose line, cap, canister, catalytic converter and the restrictor in the gasoline tank filler neck on vehicles required to use unleaded fuel.

NOTE: In order to determine if a motor vehicle was originally equipped with emissions control equipment, refer to the vehicle's emissions control information label which is usually located in the engine compartment.

3. The emission control system or device on motor vehicles manufactured for the model year 1973 or for subsequent model years is not comparable to that designed for use upon the particular vehicle as standard factory equipment.

Any new or used after market catalytic converter installed on a vehicle after December 31, 1987, shall meet and be installed in accordance with specifications established by the Environmental Protection Agency. A catalytic converter so installed shall be identified with a visible, permanent, nondestructible label or stamp which will identify the manufacturer, vehicle application and month and year of manufacture. The label shall be in accordance with the following format:

a. New converters - N/XX/YYYY/ZZZZ

b. Used converters - U/XX/YYYY/ZZZZ

N - New converter designation

U - Used converter designation

XX - Manufacturer code issued by EPA

YYYY - Numerical designation of vehicle application

ZZZZ - Month and year of manufacture (i.e. - 0188 for January, 1988)
