No motor vehicle shall be allowed to operate on the streets or highways of the District that does not comply with the exhaust emission standards prescribed pursuant to § 752, except as provided in this section.
After December 31, 1982, no owner of a motor vehicle shall operate or allow the operation of a vehicle on the streets and highways of the District that does not comply with the exhaust emission standards prescribed pursuant to § 752, except as provided in this section.
Prior to December 31, 1982, the Director may not refuse to register any motor vehicle in the District solely because of the exhaust emission levels of the vehicle.
The Director may issue a conditional approval, lasting until the next scheduled inspection, for any motor vehicle which is unable to meet exhaust emission standards prescribed in § 752 when the Director has determined that all reasonable repairs, having a minimum value of four hundred fifty dollars ($ 450), have been made and that further repairs are not mechanically nor economically feasible given the age, value, and condition of the vehicle.
The cost of any repairs covered by vehicle warranties shall not be included in the four hundred fifty dollars ($ 450) minimum adjusted repair value. The four hundred fifty dollars ($ 450) minimum repair value shall be adjusted annually in January of each year by the percentage, if any, that the Federal Consumer Price Index differs from the Federal Consumer price Index for 1989. After December 31, 1995, repairs shall be performed by an Automotive Emissions Repair Technician who has been certified or recertified pursuant to § 618.
An owner shall apply for a conditional approval with the Bureau of Motor Vehicle Services, 301 C Street, Room 1018, Washington, D.C. 20001. Before a vehicle owner may apply for a conditional approval, all exhaust emission components must be in original configuration and in compliance with 18 DCMR § 750.
The application shall contain the information requested by the Director including, but not limited to, the following:
In determining whether to grant a conditional approval pursuant to §§ 751.4 and 751.5, the Director shall consider the following factors in addition to the factors listed in §§ 751.4 and 751.5:
