## Abstract

EPA is taking direct final action to make changes to certain provisions of the evaporative and refueling emission regulations for light-duty vehicles, light-duty trucks and heavy-duty vehicles up to 14,000 pounds GVWR, the four-wheel drive dynamometer test provisions, and the vehicle labeling regulations. The evaporative changes are intended to: reduce manufacturers' certification evaporative/refueling test burden; clarify existing evaporative/refueling requirements; and better harmonize federal evaporative/refueling test procedures with California evaporative/refueling test procedures. The dynamometer changes are intended to amend outdated regulations to now include four-wheel drive provisions. The labeling changes are intended to amend regulations to remove outdated information. Today's action does not change the stringency of these existing programs.
