National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the El Toro Marine Corps Air Station Superfund Site; Correction
The Environmental Protection Agency published in the Federal Register on November 19, 2013, a document concerning the National Oil and Hazardous Substances Pollution Contingency Plan; National Priorities List: Partial Deletion of the El Toro Marine Corps Air Station Superfund Site. Inadvertently, that publication included the incorrect docket number for this Site. This document corrects that error.
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
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.
Approval and Promulgation of Implementation Plans; Texas; Attainment Demonstration for the Houston-Galveston-Brazoria 1997 8-hour Ozone Nonattainment Area
The Environmental Protection Agency (EPA) is approving the following required State Implementation Plan (SIP) submittals from the State of Texas for the Houston-Galveston-Brazoria 1997 8-hour ozone nonattainment area (HGB area): the attainment demonstration for the 1997 ozone National Ambient Air Quality Standards (NAAQS), the reasonably available control measures (RACM) demonstration for the NAAQS, the contingency measures plan in the event of failure to attain the NAAQS by the applicable attainment date, and a Motor Vehicle Emissions Budget (MVEB) for 2018, which is the attainment year for the area. EPA is also approving revisions to the air pollution control measures and General Air Quality Definitions in the Texas SIP. The revisions to the air pollution control measures include revisions to the Mass Emissions Cap and Trade (MECT) program for nitrogen oxides (NOX), revisions to the highly reactive volatile organic compound (HRVOC) emissions cap and trade (HECT) program, Voluntary Mobile Emissions Program (VMEP) measures, and Transportation Control Measures (TCMs). EPA is taking these actions in accordance with section 110 and part D of the Clean Air Act (CAA).
Approval and Promulgation of Air Quality Implementation Plans; Texas; Reasonable Further Progress Plan, Contingency Measures, Motor Vehicle Emission Budgets, and a Vehicle Miles Traveled Offset Analysis for the Houston-Galveston-Brazoria 1997 8-Hour Severe Ozone Nonattainment Area
The Environmental Protection Agency (EPA) is approving two State Implementation Plan (SIP) revisions submitted by the State of Texas on April 1, 2010, and revised on May 6, 2013, containing a reasonable further progress (RFP) plan, RFP contingency measures demonstration, motor vehicle emission budgets (MVEBs), and a vehicle miles traveled (VMT) offset analysis for the Houston-Galveston-Brazoria (HGB) 1997 8-hour ozone severe nonattainment area. EPA is approving SIP revisions in accordance with the requirements of the Clean Air Act (CAA) and EPA regulations.
Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; Approval of the 2002 Base Year Emissions Inventory for the Liberty-Clairton Nonattainment Area
As a revision to the Pennsylvania State Implementation Plan (SIP), Environmental Protection Agency (EPA) is approving the 2002 base year emissions inventory for the Liberty- Clairton nonattainment area for the 1997 annual fine particulate matter (PM2.5) National Ambient Air Quality Standard (NAAQS or standard) (hereafter ``the Liberty-Clairton Area'' or ``the Area''). EPA is also approving revisions to the Allegheny County Health Department (ACHD) regulations, which were submitted by Pennsylvania Department of Environmental Protection (PADEP). These regulatory revisions included the following amendments to ACHD regulations, which became effective on May 24, 2010: The addition of the levels of the 1997 annual PM2.5 standard and the 2006 24-hour PM2.5 standard, and the related references to the list of standards and the addition of the definition of ``PM2.5''. These actions are being taken under the Clean Air Act (CAA).
