AN ASSESSMENT OF THE SAFETY OF ONBOARD REFUELING VAPOR RECOVERY SYSTEMS

Onboard refueling vapor recovery (ORVR) systems are contained within the vehicle and their function is to capture fuel vapors which occur during vehicle refueling, to store the vapors, and to meter them into the engine for combustion. In 1988 and 1989, the National Highway Traffic Safety Administration (NHTSA), which has the responsibility for assessing the safety of these systems, indicated that it believed ORVR systems would increase safety risks. In 1991, after passage of the 1990 Clean Air Act Amendments, the NHTSA Administrator advised the Environmental Protection Agency (EPA) Administrator of continuing safety concerns and stated that NHTSA would continue its assessment of ORVR safety. Further, the Administrator indicated that NHTSA would provide EPA a report, documenting its findings. The purpose of this report is to establish NHTSA's consultation position concerning onboard safety, in accordance with statutory direction, to be used by EPA in its rulemaking deliberations concerning ORVR safety.
