WASHINGTON, DC, January 27, 2004 (ENS) - Clinton administration regulations are forcing automakers to make cleaner cars and refiners to manufacture cleaner gasoline, U.S. Environmental Protection Agency (EPA) Administrator Mike Leavitt declared Monday. The program is already bringing cleaner cars and trucks to showrooms across the nation, Leavitt said, and will guarantee Americans cleaner air for the 21st century.
EDIT
At an event in Washington, DC, Leavitt viewed more than a dozen vehicles that comply with the EPA's Tier 2 Vehicle and Gasoline Sulfur Program. The model year 2004 vehicles are among the first to comply with the standards, which tighten existing tailpipe emissions regulations and rely on low sulfur gasoline.
EDIT
The Tier 2 program, proposed and adopted under the administration of President Bill Clinton, is expected to result in vehicles that are 77 percent to 95 percent cleaner than today's cars.
It orders refiners to ensure 90 percent of the nation's gasoline supply is low sulfur by 2007 and mandates stricter tailpipe emissions limits for all cars, trucks and sport utility vehicles (SUVs) by 2009. "
