## 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 emissions of volatile organic compounds (VOCs) and particulate matter (PM) from brick and structural clay products manufacturing, rubber sports ball manufacturing, and vegetable oil extraction processes. We are approving the rescission of local rules that regulate these emission sources under the Clean Air Act (CAA or the Act).
