A federal bill ordering approval of California\u2019s state attempt to reduce greenhouse gases passed the U.S. Senate Environment and Public Works Committee May 21. Known as the state\u2019s \u201cwaiver\u201d required under the federal Clean Air Act, the bill orders the President to grant California, as well as other states that want to reduce greenhouse gases from vehicles, to approve the state standard that is more stringent than the federal one. The bill passed shortly after boxes of documents and a months-long investigation revealed that President Bush\u2019s administration persuaded the U.S. Environmental Protection Agency administrator to ignore his staff\u2019s recommendation to allow implementation of California\u2019s law. \u201cThe time has come to take the decision on California\u2019s waiver out of the hands of the EPA,\u201d stated Senator Dianne Feinstein (D-CA). She signed on to the legislation by Senator Barbara Boxer, S. 2555, which is similar to a measure Boxer authored last year that failed to advance. Implementation of AB 1493 by former Assembly-member Fran Pavley is seen as critical to successful implementation of the mandated carbon emission reductions under state law, AB 32. Two days before the passage of the federal bill, a 20-page memo released by the Congressional Committee on Oversight and Government Reform summarizing 27,000 pages of documents and several deposition of EPA staff revealed that Administrator Stephen Johnson originally favored granting the state a Clean Air Act waiver. Approval is needed to implement AB 1493 that seeks to cut carbon emissions in new vehicles by 30 percent in 2016. However, \u201cJohnson reversed his position after communication with officials in the White House,\u201d the memo concludes. \u201cOur state is going to move forward and do everything we can legally to get that waiver,\u201d responded Governor Arnold Schwarzenegger May 20 California officials sought a waiver in December 2005. Two years later, Johnson announced he was taking the unprecedented step of withholding a waiver. He defended his action by pointing to the passage of weaker federal vehicle mileage law and on grounds that California lacked a \u201ccompelling state interest\u201d because global warming was a universal problem. However, the legal justification for his decision was not released until March 6, 2008.
