The Environmental Protection Agency (EPA) is taking final action to approve revisions to the State Implementation Plan (SIP) and Operating Permit Program for the State of Iowa. This final action will amend the SIP to update incorporations by reference to EPA methods for measuring air pollutant emissions, performance testing (stack testing) and continuous monitoring. These revisions do not impact the stringency of the SIP or have an adverse effect on air quality. The EPA's approval of this rule revision is being done in accordance with the requirements of the Clean Air Act (CAA).
