On April 14, 2006, Judge Robert Collins of the US District Court for the District of Massachusetts ordered the US Environmental Protection Agency (EPA) to release [PDF] internal documents pertaining to the controversial Clean Air Mercury Rule (CAMR). The goal of the CAMR was to permanently cap and reduce mercury emissions from coal-fired power plants. Many states sued the EPA, alleging that this rule violated the Clean Air Act (CAA) because it would reduce mercury emission by 90 percent instead of the 70 percent reduction mandated by the CAA. On February 8, 2008, the US Court of Appeals for the District of Columbia Circuit ruled [PDF] against the EPA, invalidating the CAMR.
