The 13 states identified by EPA that need to make changes to their plans and issue permits that include GHG emissions include Arizona, Arkansas, California, Connecticut, Florida, Idaho, Kansas, Kentucky, Nebraska, Nevada, Oregon, Texas, and Wyoming.

This action is part of EPA’s approach to GHG permitting outlined in the spring 2010 tailoring rule under the Clean Air Act that requires states to develop EPA approved implementation plans that include requirements for issuing air permits.

EPA will work with the affected states to help them develop, submit, and obtain approval of the necessary revisions that will enable all states to issue air permits to GHG emission sources, thereby ensuring a smooth transition to GHG permitting.

In January 2011, large GHG emitters such as power plants, refineries and cement production facilities that are planning to build new facilities or make major modifications to existing ones will work with permitting authorities to identify and implement control technologies to cut their GHGs.
