EPA Provides Initial Roadmap for Greenhouse Gas Regulation Under the Clean Air Act

In a February 22, 2010 letter to several Senators (“Feb. 22 Letter”), the Environmental Protection Agency (“EPA”) set forth its timeline for the implementation of regulations for greenhouse gas (“GHG”) emissions. The EPA intends to use its existing authority under the Clean Air Act to regulate the emission of GHGs beginning in 2011. While the Feb. 22 Letter lacked specific details regarding many items of importance to industry and other stakeholders, it does provide a clear roadmap of the EPA’s plan and timing for regulating GHGs.
