Environmental Protection Agency June 21, 2013 – Federal Register Recent Federal Regulation Documents

EPA is finalizing approval of four Missouri State Implementation Plan (SIP) submissions. EPA is approving portions of two SIP submissions addressing the applicable infrastructure requirements of the Clean Air Act (CAA) for the 1997 and 2006 National Ambient Air Quality Standards (NAAQS) for fine particulate matter (PM2.5). These 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. EPA is also taking final action to approve two additional SIP submissions from Missouri, one addressing the Prevention of Significant Deterioration (PSD) program in Missouri, and another addressing the requirements applicable to any board or body which approves permits or enforcement orders of the CAA, both of which support requirements associated with infrastructure SIPs. The rationale for this action is explained in this notice and in more detail in the notice of proposed rulemaking for this action, which was published on April 10, 2013.
