The Environmental Protection Agency (EPA) is proposing to approve revisions to the Iowa State Implementation Plan (SIP) and the Operating Permits Program. The revisions include updating definitions, clarifying permit rule exemptions and permit-by-rule regulations, revising methods and procedures for performance test/stack test and continuous monitoring systems, and updating the Prevention of Significant Deterioration (PSD) regulations and Operating Permits Program. In addition, the State has removed its rules that implement the Clean Air Interstate Rule (CAIR) and revised their acid rain rules. These revisions will not impact air quality and will ensure consistency between the state and Federally approved rules.
The agency’s own summary, as published.
