The California Air Resources Board wants to implement new rules to reduce greenhouse gases from motor vehicles but they need a waiver from the EPA
to do so. They initially applied for the Waiver back in December 2005 and the EPA is finally going to have some public hearings on the request. The first of the two hearings will take place on Tuesday May 22 at the EPA conference center in Arlington, VA. A week later on May 30 a second hearing will take place in Sacremento at the California EPA headquarters. If you're interested in checking out the hearings or testifying, all the details on the locations are at the ARB website at the Read link.
