The Environmental Protection Agency (EPA) is proposing to conditionally approve two revisions to the Maricopa County portion of the Arizona State Implementation Plan (SIP) concerning fuel-burning equipment and internal combustion engines. The EPA is also proposing to disapprove one revision to the Maricopa County portion of the Arizona SIP concerning power plants. We are proposing action on Maricopa County rules that regulate these emission sources under the Clean Air Act (CAA or the "Act"). We are taking comments on these proposals and plan to follow with final actions.
The agency’s own summary, as published.
