The Environmental Protection Agency (EPA) is proposing action on revisions to the Maricopa County Air Quality Department (MCAQD) portion of the state implementation plan (SIP) for the State of Arizona. We are proposing full approval of three rules and conditional approval of three rules submitted by the MCAQD. The revisions update the MCAQD's New Source Review (NSR) permitting program for new and modified sources of air pollution. We are taking comments on this proposed rule and plan to follow with a final action.
