Abstract
The Environmental Protection Agency (EPA) is taking final action to approve revisions to the Arizona Department of Environmental Quality's (ADEQ) portion of the Arizona State Implementation Plan (SIP) that were submitted to the EPA by the ADEQ. These revisions concern the ADEQ's SIP-approved rules for the issuance of New Source Review (NSR) permits for stationary sources under the Clean Air Act (CAA or Act). This action updates the ADEQ's NSR rules in the Arizona SIP and corrects the remaining deficiencies in the ADEQ's NSR program that we identified as the basis for our limited disapprovals in final rulemaking actions in 2015 and 2016. Additionally, we are finding that the ADEQ's SIP-approved NSR permitting program meets requirements for visibility protection for major stationary sources under the Act and are removing the Federal Implementation Plans (FIPs) for the ADEQ related to these visibility protection requirements.
