ALEXANDRIA, VA – TRALA has submitted comments to the U.S. Environmental Protection Agency (EPA) in response to its announcement of a proposal to mandate on-board diagnostic systems (OBDs) to detect potential problems in the emission control systems of 2010 heavy-duty engines. In its comments, TRALA expressed several concerns with the OBD rule as currently proposed by the government. Among these concerns were:
- The need for a unified national standard for OBD programs.
- The prevention of liability for owners of rented and leased trucks if a customer’s driver fails to respond to an alert of a potential malfunction.
- The need to better identify the nature of a potential malfunction if the driver is alerted while on the road.
- The feasibility and timing of developing sensors needed to monitor for potential malfunctions.
- The need to consider an alternative approach that utilizes information gained through periodic maintenance to detect potential malfunctions.
TRALA supports the inclusion of on-board diagnostic systems to monitor the functioning of emission control systems. However, the association encourages the EPA to consider a rule that is more aligned with the industry’s existing high maintenance standards practiced at regular and frequent intervals.
