Abstract
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Maricopa County Air Quality Department (MCAQD) portion of the Arizona State Implementation Plan (SIP). These revisions concern a rule that includes definitions for certain terms that are necessary for the implementation of local rules that regulate sources of air pollution. We are approving a local rule under the Clean Air Act (CAA or the Act).
