SUPREME COURT OF U.S. HEARS ARGUMENTS IN AQMD FLEET RULES CASE

Jan, 15, 2004

WASHINGTON, D.C. – A former Solicitor General of the United States today urged the nation’s Supreme Court to reject arguments by industry and the Bush administration that seek to invalidate Southern California’s innovative clean fleet rules.

“We have asked the Supreme Court to uphold the decisions of both lower courts and allow the South Coast Air Quality Management District to continue its landmark regulations for replacing dirty diesel vehicles with clean-fuel models,” said Seth P. Waxman, U.S. Solicitor General under President Clinton and a partner with Wilmer, Cutler & Pickering in Washington, D.C.

Waxman represents AQMD -- Southern California’s clean air agency -- which is the defendant in a case brought by the Engine Manufacturers Association and the Western States Petroleum Association (US Supreme Court case No. 02-1343).  Several industry groups and the Bush administration have filed friend-of-the-court briefs on behalf of the engine manufacturers, urging the court to overturn the fleet rules.  Current U.S. Solicitor General Theodore B. Olson participated in today’s oral argument.

AQMD’s clean fleet rules, adopted in 2000 and 2001, include seven measures requiring fleet operators of transit buses, school buses, trash trucks, airport shuttles and taxis, street sweepers and heavy-duty utility trucks, to buy clean-fueled models when they replace vehicles or add to their fleets of 15 or more vehicles.  As a result of the rules, more than 5,500 clean-burning heavy-duty vehicles, powered by natural gas and other clean fuels, have been added to the region’s fleets. (See fact sheet for further details.)

“Southern California has the worst smog in the nation, in part due to diesel emissions from heavy-duty vehicles,” said Barry Wallerstein, AQMD’s executive officer.  “In addition, diesel emissions are responsible for 70 percent of the cancer risk from air pollution in the Los Angeles area.”

“Last year, we experienced our smoggiest summer in more than five years. We need every tool available to fight air pollution and protect the health of the 16 million residents of Southern California,” he said.

At issue is whether the federal Clean Air Act permits local jurisdictions such as AQMD to adopt regulations that enhance the market for clean-fueled vehicles, without requiring manufacturers to meet specific mandates such as tailpipe emission standards.

The engine manufacturers and petroleum association argued in the lower courts and the Supreme Court that AQMD's fleet rules run afoul of section 209(a) of the Clean Air Act, which prohibits local jurisdictions from adopting emission standards for new vehicles.  The law reserves to the federal government the authority to set such standards.  The only exception is the authority granted under the Clean Air Act to the State of California to set stricter automobile emission standards than those set by the federal government.

AQMD’s clean fleet rules, however, neither set emission standards nor any production mandate on engine manufacturers.  Instead, they require fleet operators to choose from the cleanest-fueled models available.

The lower courts affirmed this when ruling in favor of AQMD.  In her decision, Judge Florence-Marie Cooper of the U.S. District Court for the Central District of California stated that AQMD’s fleet rules “… impose no new emissions requirements on manufacturers whatsoever, and therefore do not run afoul of Congress’s purpose behind motor vehicle preemption: namely, the protection of manufacturers against having to build engines in compliance with a multiplicity of standards.”

Following adoption of the first six fleet rules, the Engine Manufacturers Association sued AQMD in district court in August 2000.  Plaintiffs appealed to the 9th Circuit Court of Appeals in San Francisco, which affirmed the lower court’s decision.  Plaintiffs sought review in the Supreme Court of the United States and the court agreed last year to hear the case.

Five environmental organizations including the Natural Resources Defense Council and the Sierra Club have intervened as defendants in the lawsuit in support of AQMD.  In addition, the state of California and 16 other states, along with 20 organizations including the National League of Cities, National Conference of State Legislatures, National Association of Counties and U.S. Conference of Mayors, have filed friend-of-the-court briefs supporting AQMD.

AQMD is the air pollution control agency for Orange County and major portions of Los Angeles, San Bernardino and Riverside counties.
