The California Air Resources Board (ARB), the California Attorney General’s Office, DaimlerChrysler, Isuzu Motors Limited, General Motors, and several motor vehicle dealers jointly announced on August 12, an agreement bringing an end to litigation involving the 2001 Zero Emission Vehicle regulation.The litigation involved three separate lawsuits that the manufacturers and dealers filed last year in federal and state courts in Fresno, CA. Those lawsuits challenged the ARB’s authority to promulgate the 2001 ZEV regulation. They were based on claims under several state laws, as well as a claim that federal fuel economy laws preempt the 2001 ZEV regulation. “ARB views this agreement as another successful step in the board’s implementation of a mobile source emission reduction program that will help ensure California citizens of continued improvements in California’s air quality,” said ARB Chairman Alan Lloyd. “It will free resources at ARB and within the industry to work on advanced technologies, such as fuel cell vehicles, to help us achieve California’s goal of a zero emission vehicle fleet in California.”The Federal District Court in Fresno granted a preliminary injunction prohibiting enforcement of the 2001 ZEV regulation in the 2003 and 2004 MY citing the federal government’s role in regulating fuel economy while the case moved forward on the merits. The preliminary injunction was appealed by the ARB to the Federal Ninth Circuit Court of Appeals in San Francisco. That Court heard the appeal this past February, but has not issued an opinion yet.The agreement covers all the state and federal litigation, at both the trial and appellate court levels. It calls for DaimlerChrysler, GM and the other plaintiffs to dismiss their lawsuits, and for the ARB to dismiss its appeal of the preliminary injunction, when the 2003 ZEV regulation is finalized.“General Motors believes the best way to address the environmental and energy issues facing California, our nation, and the world is through voluntary, market-based applications of innovative technologies,” said Beth Lowery, GM vice president of environment and energy. “Although GM does not agree with the concept of mandated approaches to automotive technology advancement, GM believes the proposed 2003 ZEV regulation provided the flexibility we need to move beyond the litigation.”The joint announcement of the agreement comes as the ARB is in the process of implementing an amendment to the ZEV regulation. The motor vehicle industry, including DaimlerChrysler, General Motors and other stakeholders have been working with ARB to develop the new 2003 ZEV regulation.
