Docket A-87-11 

Representatives of the American Automobile Manufacturers 

Association (AAMA), the National Highway Traffic Safety 

Administration (NHTSA), and the Environmental Protection Agency 

(EPA) met on August 5, 1993 at the AAMA office in Detroit to 

discuss safety aspects of EPA's onboard refueling vapor recovery 

rulemaking. The agenda and list of attendees are attached. 

Discussion focused on recent changed circumstances that impact 

safety issues. In particular, attendees discussed the revised 

refueling test conditions put forward for consideration at the July 

22, 1993 public hearing and the positive impact these changes, if 

adopted, would have on such concerns as system complexity and 

canister size.
