Description: 

The Environmental Protection Agency (EPA) is proposing to approve revisions to the Arizona Department of Environmental Quality's (ADEQ) portion of the Arizona State Implementation Plan (SIP). These revisions are primarily intended to make corrections to 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 proposed action will update the ADEQ's NSR rules in the SIP and correct the remaining deficiencies in the ADEQ's NSR program that we identified in final EPA rulemaking actions in 2015 and 2016. Additionally, we are proposing a finding that the ADEQ's SIP-approved NSR permitting program meets requirements for visibility protection for major NSR sources under the Act and are proposing to remove Federal Implementation Plans (FIPs) related to these requirements. We are seeking comment on our proposed action and plan to follow with a final action.
