| 2013-31250 | Approval and Promulgation of Implementation Plans; North Carolina: Non-Interference Demonstration for Removal of Federal Low-Reid Vapor Pressure Requirement for the Raleigh-Durham-Chapel Hill Area | Rule | EPA is approving the State of North Carolina's March 27, 2013, State Implementation Plan (SIP) revision to the State's approved Maintenance Plan for the Raleigh-Durham-Chapel Hill 1997 8-hour Ozone Maintenance Area (Triangle Area). Specifically, North Carolina's revision, including updated modeling, shows that the Triangle Area would continue to maintain the 1997 8-hour ozone standard if the currently applicable Federal Reid Vapor Pressure (RVP) standard for gasoline of 7.8 pounds per square inch (psi) were modified to 9.0 psi for three portions (Wake and Durham Counties, and a portion of Granville County) of the Triangle Area during the high-ozone season. The State included a technical demonstration with the revision to demonstrate that the less-stringent RVP standard of 9.0 psi in these areas would not interfere with continued maintenance of the 1997 8-hour Ozone National Ambient Air Quality Standards (NAAQS) or any other applicable standard. Approval of this SIP revision is a prerequisite for EPA's consideration of an amendment to the regulations to remove the aforementioned portions of the Triangle Area from the list of areas that are currently subject to the Federal 7.8 psi RVP requirements. In addition, EPA is also approving changes to the motor vehicle emission budgets (MVEBs) used in the 1997 8-hour ozone maintenance plan for the Triangle Area. EPA has determined that North Carolina's March 27, 2013, SIP revision with respect to the modeling changes and associated technical demonstration, and with respect to the updated MVEBs, is consistent with the applicable provisions of the Clean Air Act (CAA or Act). Should EPA decide to remove the subject portions of the Triangle Area from those areas subject to the 7.8 psi Federal RVP requirements, such action will occur in a subsequent rulemaking. | 2014-01-02 | 2014 | 1 | https://www.federalregister.gov/documents/2014/01/02/2013-31250/approval-and-promulgation-of-implementation-plans-north-carolina-non-interference-demonstration-for | https://www.govinfo.gov/content/pkg/FR-2014-01-02/pdf/2013-31250.pdf | Environmental Protection Agency | 145 | EPA is approving the State of North Carolina's March 27, 2013, State Implementation Plan (SIP) revision to the State's approved Maintenance Plan for the Raleigh-Durham-Chapel Hill 1997 8-hour Ozone Maintenance Area (Triangle Area).
