Heavy-Duty Highway Program: Revisions for Emergency Vehicles and SCR Maintenance

Docket ID: EPA-HQ-OAR-2011-1032
Agency: Environmental Protection Agency (EPA)
EPA is taking direct final action on revisions to its heavy-duty diesel regulations that will enable emergency vehicles, such as dedicated ambulances and fire trucks, to perform mission-critical lifesaving work without risking that abnormal conditions of the emission control system could lead to decreased engine power, speed, or torque. The revisions will allow manufacturers to request and EPA to approve modifications to emission control systems on emergency vehicles so they do not interfere with the vehicles' missions. This action is not expected to result in any significant changes in regulatory burdens or costs.
