Final rule.
The FMCSA revises the requirements concerning fuel tank fill rates for gasoline- and methanol-fueled light-duty vehicles contained in Subpart E of the Federal Motor Carrier Safety Regulations (FMCSRs). The purpose of the rule is to: Remove a conflict between the fuel tank fill rate requirements of the FMCSRs and those of the Environmental Protection Agency for gasoline and methanol-fueled vehicles up to 14,000 pounds (lbs) Gross Vehicle Weight Rating (GVWR); and to make permanent the terms of the exemptions previously granted to motor carriers operating certain gasoline-fueled commercial motor vehicles (CMVs) manufactured by Ford Motor Company (Ford) and by General Motors (GM). The FMCSA also incorporates into the FMCSRs previously issued regulatory guidance concerning the applicability of the agency's fuel tank rules to vehicles subject to the National Highway Traffic Safety Administration (NHTSA) fuel system integrity standard at the time of manufacture.
