The hearing, originally scheduled for May 8, will examine the new ozone national ambient air quality standards (NAAQS) and the process the Environmental Protection Agency used in setting them.

On March 12, 2008, EPA Administrator Stephen L. Johnson finalized updated NAAQS for ozone, a primary component of smog. The new ozone NAAQS are comprised of a revised primary standard to protect health and a revised secondary standard to protect the environment. In setting both standards, EPA Administrator Johnson did not accept the recommendations provided to him by EPA’s independent scientific review committee, the Clean Air Scientific Advisory Committee (CASAC). With regard to the secondary standard, Administrator Johnson’s efforts to set a new standard were overruled by the White House.

In light of new information obtained by the Committee, questions are also expected regarding the White House’s role in EPA’s action to block California’s program to regulate greenhouse gases from automobiles.
