Northeast Mississippi Intrastate	II	III	III	III	III

[37 FR 10875, May 31, 1972, as amended at 39 FR 16346, May 8, 1974]

§52.1272 Approval status.

With the exceptions set forth in this subpart, the Administrator approves Mississippi's plan for the attainment and maintenance of the national standards under section 110 of the Clean Air Act. Furthermore, the Administrator finds that the plan satisfies all requirements of part D, title 1, of the Clean Air Act as amended in 1977.

[83 FR 50018, Oct. 4, 2018]

§52.1273 Control strategy: Ozone.

(a) Determination of attainment. The EPA has determined, as of June 3, 2016, that based on 2012 to 2014 ambient air quality data, the Memphis, TN-MS-AR 2008 ozone Marginal nonattainment area has attained the 2008 ozone NAAQS. Therefore, the EPA has met the requirement pursuant to CAA section 181(b)(2)(A) to determine, based on the area's air quality data as of the attainment date, whether the area attained the standard. The EPA also determined that the Memphis, TN-MS-AR nonattainment area will not be reclassified for failure to attain by its applicable attainment date under section 181(b)(2)(A).

(b) Disapproval. The state implementation plan (SIP) revision submitted on September 3, 2019, addressing Clean Air Act section 110(a)(2)(D)(i)(I) (prongs 1 and 2) for the 2015 ozone national ambient air quality standards (NAAQS) is disapproved.

[81 FR 26709, May 4, 2016; 88 FR 9383, Feb. 13, 2023]

§52.1275 Legal authority.

(a) The requirements of §51.230(d) of this chapter are not met since statutory authority to prevent construction, modification, or operation of a facility, building, structure, or installation, or combination thereof, which indirectly results or may result in emissions of any air pollutant at any location which will prevent the maintenance of a national air quality standard is not adequate.

(b) The requirements of §51.230(f) of this chapter are not met, since section 7106-117 of the Mississippi Code could, in some circumstances, prohibit the disclosure of emission data to the public. Therefore, section 7106-117 is disapproved.

[39 FR 7282, Feb. 25, 1974, as amended at 39 FR 34536, Sept. 26, 1974; 51 FR 40676, Nov. 7, 1986]

§52.1276 Conditional approval.

[Removed and Reserved]

[88 FR 12835, Mar. 1, 2023; 89 FR 86755, Oct. 31, 2024]

§52.1277 General requirements.

(a) The requirements of §51.116(c) of this chapter are not met, since the legal authority to provide public availability of emission data is inadequate.

(b) Regulation for public availability of emission data. (1) Any person who cannot obtain emission data from the Agency responsible for making emission data available to the public, as specified in the applicable plan, concerning emissions from any source subject to emission limitations which are part of the approved plan may request that the appropriate Regional Administrator obtain and make public such data. Within 30 days after receipt of any such written request, the Regional Administrator shall require the owner or operator of any such source to submit information within 30 days on the nature and amounts of emissions from such source and any other information as may be deemed necessary by the Regional Administrator to determine whether such source is in compliance with applicable emission limitations or other control measures that are part of the applicable plan.

(2) Commencing after the initial notification by the Regional Administrator pursuant to paragraph (b)(1) of this section, the owner or operator of the source shall maintain records of the nature and amounts of emissions from such source and any other information as may be deemed necessary by the Regional Administrator to determine whether such source is in compliance with applicable emission limitations or other control measures that are part of the plan. The information recorded shall be summarized and reported to the Regional Administrator, on forms furnished by the Regional Administrator, and shall be submitted within 45 days after the end of the reporting period.

§52.1278 Control strategy: Sulfur oxides and particulate matter.

(a) In a letter dated January 30, 1987, the Mississippi Department of Natural Resources certified that no emission limits in the State's plan are based on dispersion techniques not permitted by EPA's stack height rules. This certification does not apply to: Mississippi Power-Daniel; South Mississippi Electric Power, Hattiesburg-Morrow; E.I. Dupont, Delisle Boilers 1 & 2; and International Paper, Vicksburg.

(b) Disapproval. EPA is disapproving portions of Mississippi's Infrastructure SIP for the 1997 annual and 2006 24-hour PM_2.5 NAAQS addressing section 110(a)(2)(E)(ii) that requires the State to comply with section 128 of the CAA.

§52.1279 Visibility protection.

(a) [Reserved]

(b) Disapproval. EPA has disapproved the portions of Mississippi's May 29, 2012, 2008 8-hour Ozone infrastructure SIP submission; July 26, 2012, 2008 8-hour Ozone infrastructure SIP resubmission; February 28, 2013, 2010, 1-hour NO₂ infrastructure SIP submission; June 20, 2013, 2010 1-hour SO₂ infrastructure SIP submission; and December 8, 2015, 2012, Annual PM_2.5 infrastructure SIP submission that address the visibility protection (prong 4) requirements of Clean Air Act section 110(a)(2)(D)(i)(II). EPA disapproved the prong 4 portions of these SIP submissions because Mississippi does not have a fully approved regional haze SIP that meets the requirements of 40 CFR 51.308 and because these SIP submissions do not otherwise demonstrate that emissions within the State do not interfere with other states' plans to protect visibility.

(a)(1) The owner and operator of each source and each unit located in the State of Mississippi and Indian country within the borders of the State and for which requirements are set forth under the CSAPR NO_X Ozone Season Group 1 Trading Program in subpart BBBBB of part 97 of this chapter must comply with such requirements with regard to emissions occurring in 2015 and 2016.

(2) The owner and operator of each source and each unit located in the State of Mississippi and Indian country within the borders of the State and for which requirements are set forth under the CSAPR NO_X Ozone Season Group 2 Trading Program in subpart EEEEE of part 97 of this chapter must comply with such requirements with regard to emissions occurring in 2017 through 2022.

(3) The owner and operator of each source and each unit located in the State of Mississippi and Indian country within the borders of the State and for which requirements are set forth under the CSAPR NO _X Ozone Season Group 3 Trading Program in subpart GGGGG of part 97 of this chapter must comply with such requirements with regard to emissions occurring in 2023 and each subsequent year. The obligation to comply with such requirements with regard to sources and units in the State and areas of Indian country within the borders of the State subject to the State's SIP authority will be eliminated by the promulgation of an approval by the Administrator of a revision to Mississippi's State Implementation Plan (SIP) as correcting the SIP's deficiency that is the basis for the CSAPR Federal Implementation Plan (FIP) under §52.38(b)(1) and (b)(2)(iii) for those sources and units, except to the extent the Administrator's approval is partial or conditional. The obligation to comply with such requirements with regard to sources and units located in areas of Indian country within the borders of the State not subject to the State's SIP authority will not be eliminated by the promulgation of an approval by the Administrator of a revision to Mississippi's SIP.

(4) Notwithstanding the provisions of paragraph (a)(3) of this section, if, at the time of the approval of Mississippi's SIP revision described in paragraph (a)(3) of this section, the Administrator has already started recording any allocations of CSAPR NO _X Ozone Season Group 3 allowances under subpart GGGGG of part 97 of this chapter to units in the State and areas of Indian country within the borders of the State subject to the State's SIP authority for a control period in any year, the provisions of subpart GGGGG of part 97 of this chapter authorizing the Administrator to complete the allocation and recordation of CSAPR NO _X Ozone Season Group 3 allowances to such units for each such control period shall continue to apply, unless provided otherwise by such approval of the State's SIP revision.

(5) Notwithstanding the provisions of paragraph (a)(2) of this section, after 2022 the provisions of §97.826(c) of this chapter (concerning the transfer of CSAPR NO _X Ozone Season Group 2 allowances between certain accounts under common control), the provisions of §97.826(e) of this chapter (concerning the conversion of amounts of unused CSAPR NO _X Ozone Season Group 2 allowances allocated for control periods before 2023 to different amounts of CSAPR NO _X Ozone Season Group 3 allowances), and the provisions of §97.811(e) of this chapter (concerning the recall of CSAPR NO _X Ozone Season Group 2 allowances equivalent in quantity and usability to all such allowances allocated to units in the State and Indian country within the borders of the State for control periods after 2022) shall continue to apply.

(6) Notwithstanding any other provision of this part, the effectiveness of paragraph (a)(3) of this section is stayed with regard to emissions occurring in 2023 and thereafter, provided that while such stay remains in effect, the provisions of paragraph (a)(2) of this section shall apply with regard to such emissions.

(b) The owner and operator of each source located in the State of Mississippi and Indian country within the borders of the State and for which requirements are set forth in §52.40 and §52.41, §52.42, §52.43, §52.44, §52.45, or §52.46 must comply with such requirements with regard to emissions occurring in 2026 and each subsequent year.
