Air Plan Approval; Wisconsin; NOX as a Precursor to Ozone, PM2.5 Increment Rules and PSD Infrastructure SIP Requirements

The Environmental Protection Agency (EPA) is proposing approval of a revision to Wisconsin's state implementation plan (SIP), revising portions of the State's Prevention of Significant Deterioration (PSD) and ambient air quality programs to address deficiencies identified in EPA's previous narrow infrastructure SIP disapprovals and Finding of Failure to Submit. This SIP revision request is consistent with the Federal PSD rules and addresses the required elements of the fine particulate matter (PM 2.5 ) PSD Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC) Rule. EPA is also proposing to approve elements of SIP submissions from Wisconsin regarding PSD infrastructure requirements of section 110 of the Clean Air Act (CAA) for the 1997 PM 2.5 , 1997 ozone, 2006 PM 2.5 , 2008 lead, 2008 ozone, 2010 nitrogen dioxide (NO 2 ), 2010 sulfur dioxide (SO 2 ), and 2012 PM 2.5 National Ambient Air Quality Standards (NAAQS). The infrastructure requirements are designed to ensure that the structural components of each state's air quality management program are adequate to meet the state's responsibilities under the CAA.
