40 CFR Part 81, Subpart C - Section 107 Attainment Status Designations

The Environmental Protection Agency (EPA) is approving the portion of a State Implementation Plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), on October 15, 2009, that addresses reasonably available control measures (RACM), including reasonably available control technology (RACT), for the Tennessee portion of the Chattanooga, TN-GA-AL nonattainment area for the 1997 fine particulate matter (PM 2.5 ) national ambient air quality standards (NAAQS) (hereinafter referred to as the “Chattanooga TN-GA-AL Area” or “Area”). Additionally, EPA is taking three separate final actions related to Tennessee's November 13, 2014 request to redesignate the Tennessee portion of the Area to attainment for the 1997 PM 2.5 NAAQS and associated SIP revision containing a plan for maintaining attainment of the standard in the Chattanooga TN-GA-AL Area. In these three actions, EPA is determining that the Area is continuing to attain the 1997 PM 2.5 NAAQS; approving and incorporating the State's plan for maintaining attainment of the standard in the Area, including the 2025 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO X ) and PM 2.5 for the Tennessee portion of this Area, into the SIP; and redesignating the Tennessee portion of the Area to attainment for the 1997 PM 2.5 NAAQS. In addition to the four final actions described above, EPA is also finding the 2025 MVEBs for the Tennessee portion of the Area adequate for the purposes of transportation conformity.

Environmental Protection Agency (EPA) is approving in part and disapproving in part State Implementation Plan (SIP) revisions submitted by the State of Nevada pursuant to the requirements of the Clean Air Act (CAA) for the 2008 ozone national ambient air quality standards (NAAQS), the 2010 nitrogen dioxide (NO 2 ) NAAQS and the 2010 sulfur dioxide (SO 2 ) NAAQS. The CAA requires that each state adopt and submit a SIP for the implementation, maintenance, and enforcement of each NAAQS promulgated by the EPA, and that EPA act on such SIPs. Nevada has met most of the applicable requirements. Where EPA is disapproving, in part, Nevada's SIP revisions, the deficiencies have already been addressed by a federal implementation plan (FIP).

The Environmental Protection Agency (EPA) is taking final action to approve, as a revision to the California State Implementation Plan (SIP), California's request to redesignate the Mammoth Lakes nonattainment area to attainment for the 1987 National Ambient Air Quality Standard (NAAQS) for particulate matter of ten microns or less (PM 10 ). Also, EPA is taking final action to approve the PM 10 maintenance plan for the Mammoth Lakes area and the associated motor vehicle emissions budgets for use in transportation conformity determinations. Lastly, EPA is finalizing our approval of the 2012 attainment year emissions inventory. We are taking these final actions because the SIP revision meets the requirements of the Clean Air Act and EPA guidance for maintenance plans and motor vehicle emissions budgets.

The Environmental Protection Agency (EPA) is approving the Commonwealth of Pennsylvania's request to redesignate to attainment the Pittsburgh Nonattainment Area (Pittsburgh Area or Area) for the 1997 annual and 2006 24-hour fine particulate matter (PM 2.5 ) national ambient air quality standard (NAAQS or standard). EPA has determined that the Pittsburgh Area attained both the 1997 annual and 2006 24-hour PM 2.5 NAAQS. In addition, EPA is approving as a revision to the Pennsylvania State Implementation Plan (SIP) the associated maintenance plan to show maintenance of the 1997 annual and 2006 24-hour PM 2.5 NAAQS through 2025 for the Pittsburgh Area. The maintenance plan includes the 2017 and 2025 PM 2.5 and nitrogen oxides (NO X ) motor vehicle emissions budgets (MVEBs) for the Pittsburgh Area for the 1997 annual and 2006 24-hour PM 2.5 NAAQS, which EPA is approving for transportation conformity purposes. Furthermore, EPA is approving the 2007 emissions inventories for the 1997 annual PM 2.5 NAAQS and the 2011 emissions inventories for the 2006 24-hour PM 2.5 NAAQS included in the maintenance plan for the Pittsburgh Area. These actions are being taken under the Clean Air Act (CAA).

The Environmental Protection Agency (EPA) is making a technical amendment to the Code of Federal Regulations to restore the inadvertent deletion of the entry for “Rest of State” from the table listing California air quality planning area designations for particulate matter of ten microns of less (PM 10 ).

Pursuant to its authority under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is promulgating this final action to make technical amendments to address several minor, inadvertent and nonsubstantive errors in the regulatory text establishing the air quality designations for the 2006 24-hour fine particle (PM 2.5 ) National Ambient Air Quality Standards (NAAQS), 1997 annual PM 2.5 NAAQS, and 1987 annual coarse particle (PM 10 ) NAAQS. Consistent with the EPA's interpretation of the good cause exemption provisions outlined in the Administrative Procedure Act, this action is being taken without notice and comment.

The Environmental Protection Agency (EPA) is taking three separate final actions related to a state implementation plan (SIP) revision submitted by the State of North Carolina, through the North Carolina Department of Environment and Natural Resources, Department of Air Quality (NC DAQ), on April 16, 2015. These final actions are for the North Carolina portion of the bi-state Charlotte-Rock Hill, North Carolina-South Carolina 2008 8-hour ozone nonattainment area (hereinafter referred to as the “bi-state Charlotte Area” or “Area”). The bi-state Charlotte Area consists of Mecklenburg County in its entirety and portions of Cabarrus, Gaston, Iredell, Lincoln, Rowan and Union Counties, North Carolina; and a portion of York County, South Carolina. Regarding South Carolina's request to redesignate the South Carolina portion of the Area and its maintenance plan for the 2008 8-hour ozone NAAQS, EPA will address this in a separate action. In the three actions for the North Carolina bi-state Charlotte Area, EPA determines that the bi-state Charlotte Area is attaining the 2008 8-hour ozone National Ambient Air Quality Standards (NAAQS); approves and incorporates the State's plan for maintaining attainment of the 2008 8-hour ozone standard in the Area, including the 2014 and 2026 sub-area motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO X ) and volatile organic compounds (VOC) for the North Carolina portion of this Area into the SIP; and redesignates the North Carolina portion of the bi-state Charlotte Area to attainment for the 2008 8-hour ozone NAAQS. Additionally, EPA finds the 2014 and 2026 sub-area MVEBs for the North Carolina portion of the bi-state Charlotte Area adequate for the purposes of transportation conformity.

The Environmental Protection Agency (EPA) is proposing to reclassify to Serious the Salt Lake City, Provo, and the Logan portion of the Logan, UT/ID nonattainment areas in Utah for the 2006 24-hour fine particulate matter (PM 2.5 ) National Ambient Air Quality Standard (NAAQS). Our proposal is based on EPA's determination that the areas cannot practicably attain this standard by the applicable Moderate area attainment date of December 31, 2015. Upon final reclassification as a Serious area, Utah will be required to submit a Serious area plan for each nonattainment area, including demonstrations that the individual plans for each area provides for attainment of the 2006 PM 2.5 NAAQS by the applicable Serious area attainment date.

The Environmental Protection Agency (EPA) is approving the portion of a State Implementation Plan (SIP) revision submitted by the State of Tennessee, through the Tennessee Department of Environment and Conservation (TDEC), on October 15, 2009, that addresses reasonably available control measures (RACM), including reasonably available control technology (RACT), for the Tennessee portion of the Chattanooga, TN-GA-AL nonattainment area for the 1997 fine particulate matter (PM 2.5 ) national ambient air quality standards (NAAQS) (hereinafter referred to as the “Chattanooga TN-GA-AL Area” or “Area”). Additionally, EPA is taking three separate final actions related to Tennessee's November 13, 2014 request to redesignate the Tennessee portion of the Area to attainment for the 1997 PM 2.5 NAAQS and associated SIP revision containing a plan for maintaining attainment of the standard in the Chattanooga TN-GA-AL Area. In these three actions, EPA is determining that the Area is continuing to attain the 1997 PM 2.5 NAAQS; approving and incorporating the State's plan for maintaining attainment of the standard in the Area, including the 2025 motor vehicle emission budgets (MVEBs) for nitrogen oxides (NO X ) and PM 2.5 for the Tennessee portion of this Area, into the SIP; and redesignating the Tennessee portion of the Area to attainment for the 1997 PM 2.5 NAAQS.

The Environmental Protection Agency (EPA) is proposing to approve two revisions to the Nevada state implementation plan (SIP). The first revision provides a demonstration of implementation of best available control measures (BACM) for control of particulate matter with an aerodynamic diameter less than or equal to a nominal ten micrometers (PM 10 ) within Truckee Meadows. The second revision is a plan that provides for the maintenance of the national ambient air quality standard for PM 10 in Truckee Meadows through 2030, includes an emissions inventory consistent with attainment, and establishes motor vehicle emissions budgets. In connection with these proposed approvals, the EPA is proposing to determine that major stationary sources of PM 10 precursors do not contribute significantly to elevated PM 10 levels in the area. Also, based in part on the proposed approvals of the BACM demonstration and maintenance plan and proposed determination regarding PM 10 precursors, the EPA is proposing to approve the State of Nevada's request for redesignation of the Truckee Meadows nonattainment area to attainment for the PM 10 standard. Lastly, the EPA is proposing to delete the area designation for Truckee Meadows for the revoked national ambient air quality standard for total suspended particulate (TSP). The EPA is proposing these actions because the SIP revisions meet the applicable statutory and regulatory requirements for such plans and related motor vehicle emissions budgets and because the area meets the Clean Air Act requirements for redesignation of nonattainment areas to attainment.

The Environmental Protection Agency (EPA) is making a technical amendment to the Code of Federal Regulations to restore the inadvertent deletion of the entry for “Rest of State” from the table listing California air quality planning area designations for particulate matter of ten microns of less (PM 10 ).
