Approval and Promulgation of State Implementation Plan Revisions; Infrastructure Requirements for the 1997 and 2006 PM2.5
EPA is approving State Implementation Plan (SIP) submissions from the State of Colorado to demonstrate that the SIP meets the infrastructure requirements of the Clean Air Act (CAA) for the National Ambient Air Quality Standards (NAAQS) promulgated for PM2.5 on July 18, 1997 and on October 17, 2006. The CAA requires that each state, after a new or revised NAAQS is promulgated, review their SIPs to ensure that they meet infrastructure requirements. The State of Colorado provided infrastructure SIP submissions on April 4, 2008 and June 4, 2010 for the 1997 and 2006 PM2.5 NAAQS, respectively. In addition, EPA is approving portions of SIP revisions submitted by the State of Colorado on May 11, 2012 and May 13, 2013. The revisions update Regulation 3 of the Air Quality Control Commission permitting requirements for the Prevention of Significant Deterioration (PSD) program to incorporate the required elements of the 2008 PM2.5 NSR Implementation Rule and the 2010 PM2.5 Increment Rule.
Approval and Promulgation of Implementation Plans; North Carolina; Removal of Stage II Gasoline Vapor Recovery Program
EPA is taking final action to approve changes to the North Carolina State Implementation Plan (SIP) submitted by the State of North Carolina Department of Environment and Natural Resources (NC DENR), Division of Air Quality on September 18, 2009, for the purpose of removing Stage II vapor control requirement contingency measures for new and upgraded gasoline dispensing facilities in the State. The September 18, 2009, SIP revision also addresses several non-Stage II related rule changes. However, action on the other portions for the September 18, 2009, SIP revision is being addressed in a separate rulemaking action. EPA has determined that North Carolina's September 18, 2009, SIP revision regarding the Stage II vapor control requirements is approvable because it is consistent with the Clean Air Act (CAA or Act).
Designation of Areas for Air Quality Planning Purposes; California; Morongo Band of Mission Indians

EPA is also taking final action to revise the boundaries of certain Southern California air quality planning areas to designate the Indian country of the Morongo Band of Mission Indians, California as a separate air quality planning area for the one-hour and 1997 eight-hour ozone standards.
