The SIP revision modifies the States annual emissions reporting regulation by removing the annual emissions reporting requirement for certain non-Title V facilities in geographic areas that have been redesignated to attainment for the 1979
1-hour ozone national ambient air quality standards NAAQS or standards and in the areas listed in the rule that have been redesignated to attainment for the 1997 8-hour ozone NAAQS, with the exception of the geographic areas that have been redesignated to attainment for the 2008
8-hour ozone NAAQS. The SIP revision also makes minor changes that do not significantly alter the meaning of the regulation. EPA is approving this revision pursuant to the Clean Air Act CAA or Act.

SUPPLEMENTARY INFORMATION:
I. Background In 1979, EPA promulgated a NAAQS
for ozone, setting the standard at 0.12
parts per million ppm averaged over a 1-hour time frame. See 44 FR 8202
February 8, 1979. In 1997, EPA
promulgated a revised NAAQS for ozone, setting the standard at 0.08 ppm averaged over an 8-hour time frame. See 62 FR 38856 July 18, 1997.1 In 2008, EPA revised the level of the 8-hour ozone standard to 0.075 ppm. See 73 FR
16436 March 27, 2008.2 The promulgation of a new or revised NAAQS triggers a CAA requirement for EPA to designate as nonattainment any area that violates the NAAQS or contributes to a violation in a nearby area. On November 6, 1991, EPA
published designations and classifications for the 1979 1-hour ozone NAAQS.3 See 56 FR 56694. EPA initially published designations and classifications for the revised 1997 8hour and revised 2008 8-hour ozone standards on April 30, 2004 69 FR
23858 and May 21, 2012 77 FR 30088, 1 EPA has revoked the 1979 and 1997 ozone standards. See 69 FR 23951 April 30, 2004 and 80
FR 12264 March 6, 2015, respectively.
2 EPA revised the level of the 8-hour ozone standard to 0.070 ppm in 2015 and designated the entire state as attainment/unclassifiable for that NAAQS in 2017. See 80 FR 65296 October 22, 2015 and 82 FR 54232 November 16, 2017.
3 EPA designated the following geographic areas in North Carolina as nonattainment for the 1979
ozone standard: Davidson, Durham, Forsyth, Gaston, Guilford, Mecklenburg, and Wake Counties, the Dutchville Township in Granville County, and that part of Davie County bounded by the Yadkin River, Dutchmans Creek, North Carolina Highway 801, Fulton Creek and back to the Yadkin River.

respectively. The geographic areas designated as nonattainment in North Carolina for the 1997 8-hour ozone standard included the CharlotteGastonia-Rock Hill, NC-SC Area the North Carolina portion is hereinafter the 1997 Charlotte Area.4 The geographic areas designated as nonattainment in North Carolina for the 2008 ozone standard are part of an area known as the Charlotte-Rock Hill, NC-SC Area the North Carolina portion is hereinafter the 2008 Charlotte Area.5
EPA redesignated North Carolinas 1979

North Carolina was required to develop nonattainment SIP revisions addressing the CAA requirements for its ozone nonattainment areas. Among other things, North Carolina was required to address the annual emissions reporting requirement in CAA
section 182a3B, which requires each state with an ozone nonattainment area to submit a SIP revision requiring stationary sources that emit 25 tons per year tpy or more of nitrogen oxides NOX or volatile organic compounds VOC within the nonattainment area to provide certified annual emissions statements to the state showing actual annual NOX and VOC emissions from the sources.
