Approval and Promulgation of Implementation Plans South Carolina:

Interstate Transport of Pollution

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) revision submitted by the South Carolina Department of Health and

Environmental Control (SC DHEC), on June 25, 2007, pursuant to the requirements of section 110(a)(2)(D)(i) of the Clean Air Act (CAA).

Section 110(a)(2)(D)(i) of the CAA requires each state to submit a SIP revision within three years of a revision to the national ambient air quality standards (NAAQS). The SIP revision must include provisions adequate to address emissions that may adversely affect another state's air quality through interstate transport of the revised NAAQS pursuant to the CAA. On July 18, 1997, EPA published revisions to the NAAQS for ozone and fine particulate matter (PM2.5). SC DHEC's June 25, 2007, SIP revision addresses the elements required by section 110(a)(2)(D)(i) of the CAA with regard to ozone and PM2.5, and as a result, it is approvable.

DATES: Comments must be received on or before June 23, 2008.

   SUPPLEMENTARY INFORMATION:

1. What Is the Background for EPA's Action?

   EPA is proposing to approve a SIP revision submitted by SC DHEC on

   June 25, 2007. This SIP revision addresses the requirements of CAA section 110(a)(2)(D)(i). This SIP revision was public noticed on April 25, 2007, and a public hearing was held on May 30, 2007; no comments were received.

   Section 110(a)(1) of the CAA requires that each state submit to EPA a SIP revision within three years after promulgation of a NAAQS.

   Section 110(a)(2)(D)(i) requires that the aforementioned SIP contain adequate provisions to prohibit any source or other type of emissions activity within the state from emitting any air pollutant in amounts which will:

   (I) contribute significantly to nonattainment in, or interfere with maintenance by, any other State with respect to any such national primary or secondary ambient air quality standard, or (II) interfere with measures required to be included in the applicable implementation plan for any other State under part C of this subchapter to prevent significant deterioration of air quality or to protect visibility * * *

   CAA section 110(a)(2)(D)(i)(I) and (II). The provision quoted above can be described as including four separate but related elements that an applicable SIP revision should include: (1) Provisions prohibiting a state from contributing significantly to nonattainment of the NAAQS for areas in another state; (2) provisions prohibiting interference with maintenance of the NAAQS in another state; (3) provisions prohibiting interference with measures required to meet implementation plan requirements related to prevention of significant deterioration (PSD) for any other state; and (4) provisions prohibiting interference with measures required to meet implementation plan requirements related to regional haze for any other state.

   On July 18, 1997, EPA published revisions to the NAAQS for ozone

   (62 FR 2) and PM2.5(62 FR 38652). The current SIP revision by South Carolina is intended to satisfy the requirements of Section 110(a)(2)(D)(i) of the CAA for the 1997 ozone and PM2.5

   NAAQS. As is described below, the current SIP revision by South

   Carolina adequately addresses all four sub-elements of section 110(a)(2)(D)(i) of the CAA, and is therefore approvable.

   The first two sub-elements of section 110(a)(2)(D)(i) of the CAA regard the prohibition of one state from interfering with maintenance or attainment of a NAAQS in another state. These first two sub-elements of Section 110(a)(2)(D)(i) were met by South Carolina's SIP revision regarding EPA's Clean Air Interstate Rule (CAIR). EPA promulgated CAIR on May 12, 2005 (70 FR 25162). CAIR requires certain states to reduce emissions of sulfur dioxide (SO2) and nitrogen oxides

   (NOX) that significantly contribute to, and interfere with maintenance of, the NAAQS for PM2.5and/or ozone in any downwind state, thus addressing the two revised NAAQS pollutants at issue as well as the issue of interstate interference with maintenance or attainment of the NAAQS. CAIR established state budgets for

   SO2and NOXand requires states to submit SIP revisions that implement these budgets in states that EPA concluded did contribute to nonattainment in other states.

   South Carolina is a CAIR-State for both ozone and PM2.5

   (see 60 FR 25162, May 12, 2005). Because South Carolina adopted CAIR,

   EPA has already concluded that South Carolina can meet its section 110(a)(2)(D)(i) obligations to address the significant contribution and interference with maintenance requirements by complying with the CAIR requirements. EPA published a direct final action approving the South

   Carolina CAIR SIP revision for its allocation methodology on October 9, 2007 (72 FR 57257). In addition, South Carolina remains covered by the

   CAIR Federal Implementation Plan (FIP) for the remainder of its trading program. Therefore, EPA has determined that through the above actions,

   South Carolina has adequately addressed the first two sub-elements of the CAA section 110(a)(2)(D)(i) requirements (i.e.,

   Page 29733

   to prevent emissions that contribute significantly to other state's nonattainment of, or interfere with the maintenance of, the NAAQS).

   The third CAA section 110(a)(2)(D)(i) sub-element addressed by

   South Carolina in its June 25, 2007, submittal relates to the prevention of significant deterioration (PSD) program. For ozone and

   PM2.5, South Carolina has met its obligation by confirming that major sources in the State are currently subject to PSD and/or

   Nonattainment New Source Review programs that implement the 1997 8-hour ozone standard and the PM2.5standard.

   The fourth CAA section 110(a)(2)(D)(i) sub-element regards visibility. South Carolina addressed this fourth sub-element through its SIP submittal describing its Regional Haze Implementation Plan.

   This revision was submitted to EPA on December 17, 2007.

2. Proposed Action

   EPA is now proposing to approve South Carolina's CAA section 110(a)(2)(D)(i) SIP revision submitted on June 25, 2007. EPA has reviewed South Carolina's 110(a)(2)(D)(i) revision and has found that it is consistent with the relevant CAA requirements as discussed above.

3. Statutory and Executive Order Reviews

   Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable

   Federal regulations. 42 U.S.C. 7410(k); 40 CFR 52.02(a). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves state law as meeting Federal requirements and does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

   Is not a ``significant regulatory action'' subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);

   Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);

   Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory

   Flexibility Act (5 U.S.C. 601 et seq.);

   Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded

   Mandates Reform Act of 1995 (Pub. L. 104-4);

   Does not have Federalism implications as specified in

   Executive Order 13132 (64 FR 43255, August 10, 1999);

   Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);

   Is not a significant regulatory action subject to

   Executive Order 13211 (66 FR 28355, May 22, 2001);

   Is not subject to requirements of section 12(d) of the

   National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and

   Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under

   Executive Order 12898 (59 FR 7629, February 16, 1994).

   In addition, this rule does not have tribal implications as specified by Executive Order 13175 (65 FR 67249, November 9, 2000), because the SIP is not approved to apply in Indian country located in the State, and EPA notes that it will not impose substantial direct costs on tribal governments or preempt tribal law.
