caretNotice of public hearing/comment concerning the following proposed actions: Amendments to Regulation .02 under Chapter COMAR 26.11.20 concerning exemptions for new motor vehicles sold at Dealers, wholesalers, auto insurers, and auctions. 

The Department of the Environment held a virtual public hearing on October 26, 2022.

The purpose of this action is to provide an exemption for new motor vehicles sold by a Dealer, vehicles sold at wholesale and by auto insurers, and vehicles sold at auctions conducted by auctioneers not in title as specified under COMAR 26.11.20.02 Motor Vehicle Emission Control Devices. On February 7, 2022, the Maryland Department of the Environment (MDE or the Department) expanded prohibitions pertaining to (1) the removal or alteration of a motor vehicle's air pollution control systems; (2) the operation of motor vehicles with removed, altered, or inoperative air pollution control systems; (3) the manufacture, sale, installation, and use of any device that prevents a motor vehicle's air pollution control system from operating as originally designed; and (4) the offering for sale, sale, lease, auction or transfer of any motor vehicle with removed, altered, or inoperative air pollution control systems.

Section (4) above applies to the retail transaction of motor vehicles that occur between a licensed dealer and the consumer. Under this action, exemptions are being extended to cover new motor vehicles, vehicles sold at wholesale, and by auto insurers that take ownership of motor vehicles associated with total loss claims, which occur when a vehicle sustains so much damage it is more economical for the insurance company to purchase the vehicle for its pre-accident value rather than repair the vehicle. Auto insurers typically dispose of those vehicles at auction in an effort to recoup some of the claim costs. Exemptions will also cover auctions acting on behalf of a seller, secured party or owner where the title does not pass to the auctioneer or to the facilitating auction location. This action will exempt from compliance with COMAR 26.11.20.02 auto insurers and those transactions identified in COMAR 26.11.20.02C(1) that are conducted by auctioneers not in title, as specified under the conditions outlined in proposed COMAR 26.11.20.02C.

The Department will continue to enhance compliance investigations pertaining to the operation and transaction of tampered vehicles. The Department will continue to monitor auctions to determine whether the exemption for auctions results in significantly tampered vehicles operating on Maryland roadways, despite undergoing state safety inspections that examine emission control systems.

The proposed amendments to COMAR 26.11.20.02 will be submitted to the U.S. Environmental Protection Agency (EPA) for approval as part of Maryland’s State Implementation Plan (SIP).​​
