On October 1, 2007, July 18, 2011, June 17, 2013, August 8, 2014, January 20, 2016, and July 27, 2016, SC DHEC submitted SIP revisions to EPA for approval that involve changes to South Carolina’s minor source permitting regulations to clarify and streamline the State’s federally-approved preconstruction and operating permitting program. This program requires minor stationary sources planning to construct or modify sources of air pollutants to first obtain a construction permit and to obtain and maintain operating permits in accordance with the South Carolina Code of Regulations Annotated (S.C. Code Ann. Regs.) at Regulation 61–62.1, Section II—‘‘Permit Requirements.’’ The portion of the SIP-approved permitting program covering construction permits is generally referred to as the minor source permitting program or the minor NSR program to distinguish it from additional permitting requirements for major sources of air pollutants.1 The portion of the SIP-approved permitting program covering minor source operating permits is referred to as the federally enforceable state operating permit (FESOP) program. The changes made in these submittals clarify the applicability, streamline the permitting process, provide more options for the 1 EPA’s regulations governing the implementation of NSR permitting programs are contained in 40 CFR 51.160–.166; 52.21, .24; and part 51, Appendix S. The CAA NSR program is composed of three separate programs: prevention of significant deterioration (PSD), nonattainment new source review (NNSR), and Minor NSR. PSD is established in part C of title I of the CAA and applies to major stationary sources in areas that meet the national ambient air quality standards (NAAQS)— ‘‘attainment areas’’—as well as areas where there is insufficient information to determine if the area meets the NAAQS—‘‘unclassifiable areas.’’ The NNSR program is established in part D of title I of the CAA and applies to major stationary sources in areas that are not in attainment of the NAAQS— ‘‘nonattainment areas.’’ The Minor NSR program applies to stationary sources that do not require PSD or NNSR permits.

The changes addressed in this proposed rulemaking also correct typographical errors, make internal references consistent, and recodify sections of the existing rules. In this action, EPA is proposing to approve certain portions of these SIP submissions that make changes to South Carolina’s minor NSR regulations and FESOP requirements. EPA is not acting on a portion of the revisions to Regulation 61–62.1, Section II—‘‘Permit Requirements.’’ Specifically, EPA is not acting on the renumbering and minor administrative language changes to paragraph G.6.— ‘‘Emergency Provisions,’’ in the October 1, 2007, submittal, nor the minor additional language changes to this portion of the minor source permitting regulations included in the August 8, 2014, submittal.2 At this time, EPA is not acting on the following changes included in the October 1, 2007, submittal: Regulation 61–62.5, Standard No. 4—‘‘Emissions from Process Industries’’; and Regulation 61–62.5, Standard No. 5.2— ‘‘Control of Oxides of Nitrogen (NOX).’’ EPA is also not acting on changes in the July 18, 2011, submittal to the following regulations in South Carolina’s SIP: Regulation 61–62.1, Section I—‘‘Definitions’’; Regulation 61–62.3—‘‘Air Pollution Episodes’’; Regulation 61–62.5, Standard No. 1— ‘‘Emissions from Fuel Burning Operations’’; Regulation 61–62.5, Standard No. 4—‘‘Emissions from Process Industries’’; Regulation 61–62.5, Standard No. 6—‘‘Alternative Emission Limitation Options (Bubble)’’; Regulation 61–62.5, Standard No. 7— ‘‘Prevention of Significant Deterioration’’; and Regulation 61–62.5, Standard No. 7.1—‘‘Nonattainment New Source Review.’’ EPA approved the changes to Regulation 61–62.5, Standard No. 2—‘‘Ambient Air Quality Standards,’’ included in the July 18, 2011, submittal, on April 3, 2013 (78 FR 19994). EPA is not acting on the changes included in the June 17, 2013, submittal to the following regulations: Regulation 61–62.1, Section I—‘‘Definitions’’; Regulation 61–62.1, Section IV— ‘‘Source Tests’’; Regulation 61–62.3— ‘‘Air Pollution Episodes’’; Regulation 61–62.5, Standard No. 4—‘‘Emissions from Process Industries’’; and 2 In this action, EPA is not proposing to approve or disapprove revisions to any existing emission limitations that apply during start up, shut down and malfunction events.

Analysis of State’s Submittal A. Overview of Changes to Section II— ‘‘Permit Requirements’’ South Carolina has a SIP-approved minor source permitting program at Regulation 61–62.1, Section II—‘‘Permit Requirements.’’ These regulations include requirements for obtaining preconstruction and operating permits for different types of minor sources. The program covers ‘‘true minor’’ sources, which have the potential to emit (PTE) of certain pollutants below major sources thresholds for new sources and modifications. The SIP-approved minor source permitting program also includes provisions for issuing permits that establish federally enforceable emission limits to restrict the PTE of certain pollutants below major source and major modification applicability thresholds: ‘‘synthetic minor’’ permits establish these limits for sources obtaining construction permits, and ‘‘conditional major’’ permits establish these emission limits in the corresponding operating permits. South VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 Carolina initially revised its minor NSR and FESOP rules in the October 1, 2007, submittal to clarify and streamline requirements for obtaining minor source construction and operating permits. The July 18, 2011, June 17, 2013, August 8, 2014, January 20, 2016, and July 27, 2017, submittals make other clarifying and administrative changes, which are discussed for each subsection of the regulation below. EPA has reviewed the proposed changes to the minor source construction and operating permitting regulations and preliminarily finds them to be consistent with CAA sections 110(a)(2)(C) and 110(l), EPA’s minor NSR regulations found at 40 CFR 51.160—164, and the criteria applicable to an approvable State FESOP program. B. Analysis of Changes to Each Section 1. Section II.A.—‘‘Construction Permits’’ Regulation 61–62.1, Section II.A— ‘‘Construction Permits’’ specifies applicability and certain requirements for obtaining permits for sources seeking to construct or modify emissions units. The October 1, 2007, submittal makes several changes to paragraph A. as follows: (1) Adds allowed preconstruction activities at subparagraph A.1.d. for true minor sources (i.e., minor sources that are not synthetic minor sources); (2) adds the requirement that written notification be provided to the Department marking the commencement of construction and initial startup; (3) adds language requiring compliance with all terms, limits, and conditions of Departmentissued construction permits; (4) adds time constraints for the validity of issued construction permits; and (5) removes the descriptions of permit application requirements from former paragraph A.2. to create a standalone subsection C. for construction permits, and to detail more specific requirements for other types of permits in other paragraphs. The July 18, 2011, submittal makes subsequent clarifying and administrative changes to Section II.A., consolidating former subparagraph A.1.a. and paragraph A.5. into an introductory paragraph applicable to the entirety of Regulation 61–62.1, Section II. The submittal also makes other renumbering and administrative edits to the remaining subparagraphs. The language moved to an introductory paragraph for Section II states: (1) The regulation will not supersede any state or federal requirements nor special permit conditions unless it imposes a more restrictive limit; (2) sources must PO 00000 Frm 00036 Fmt 4702 Sfmt 4702 comply with all terms, conditions, and limitations of any permit issued by SC DHEC for sources or activities at its facility; and (3) a source’s permit status may change if new regulatory requirements become applicable. The effect of moving this language from subsection A. is to clarify that it is applicable to all of Section II—meaning it applies to any types of permits issued by the SC DHEC rather than only construction permits. The August 8, 2014, submittal further modifies Section II.A. by making administrative edits and adding additional allowed preconstruction activities for true minor sources at subparagraph A.1.c, originally added in the October 1, 2007, submittal as subparagraph A.1.d. The revision to subparagraph A.1.c.— added to the Regulation as A.1.d. in the October 1, 2007, submittal, renumbered in the July 18, 2011, submittal, and updated in the August 8, 2014, submittal—allows certain preconstruction activities prior to obtaining a final construction permit, provided that specific conditions are met. EPA has preliminarily determined that the preconstruction activities provision is consistent with the requirements of CAA sections 110(a)(2)(C) and 110(l), and federal regulations at 40 CFR 51.160—51.164. Section 110(a)(2)(C) of the CAA requires that state SIPs include a program for regulating the construction and modification of stationary sources as necessary to ensure that the NAAQS are maintained. Federal regulations at 40 CFR 51.160(b) require states to have legally enforceable procedures to prevent construction or modification of a source if it would violate any SIP control strategies or interfere with attainment or maintenance of the NAAQS. Federal regulations limit the types of allowed preconstruction activities for new and modified major sources at 40 CFR 51.165(a)(1)(xv), 51.166(b)(11), and 52.21(b)(11) and, as discussed below, South Carolina has adopted these provisions into its SIP. But federal regulations do not impose a corresponding limitation on preconstruction activities for minor sources. SC DHEC provided additional clarification of its allowed minor source preconstruction activities in a December 30, 2016, letter, which is included in the Docket for this proposed action. In this letter, SC DHEC first explains that ‘‘[a]llowed preconstruction activities are extremely limited in nature and do not include construction of that actual process unit itself.’’ The State also points to a requirement under Section II.C.3.n. that sources applying for E:\FR\FM\17AUP1.SGM 17AUP1 sradovich on DSK3GMQ082PROD with PROPOSALS Federal Register / Vol. 82, No. 158 / Thursday, August 17, 2017 / Proposed Rules construction permits demonstrate emissions will not interfere with attainment or maintenance of the NAAQS. This requirement corresponds to Section II.A.2. of the Regulation, which states that permits will not be issued if emissions interfere with any state or federal standard. SC DHEC also points to its memorandum regarding allowed preconstruction activities for major sources prior to obtaining PSD permits.3 SC DHEC notes that its minor source preconstruction activities provisions mirror the federal limits on major source preconstruction activities, with the exception of one additional activity: Allowing a facility to pour concrete foundation prior to obtaining a construction permit. This activity is only prohibited for major sources or major modifications prior to obtaining a permit in accordance with the definition of ‘‘begin actual construction’’ in the federal PSD regulations at 40 CFR 51.166(b)(11) and 52.21(b)(11), and the NNSR regulations at 51.165(a)(1)(xv). As SC DHEC explains in its clarifying letter, Section II.A.1.c.—which specifies which sources may engage in preconstruction activities—explicitly excludes ‘‘sources not requesting to use federally enforceable construction permit conditions to limit potential to emit, sources not subject to regulations with more stringent start of construction limitations, or sources not otherwise exempt from permit requirements.’’ In other words, the regulation excludes, among other sources, major sources subject to PSD regulations or CAA section 112 requirements for hazardous air pollutants (i.e., major sources and modifications). In its December 30, 2016 letter, SC DHEC references Section II.A.1.d., which clearly states that the owners or operators of any sources that would not qualify for the issuance of a construction permit assume the financial risk of commencing the preconstruction activities listed in Section II.A.1.c. SC DHEC also notes that a source could be subject to an enforcement action under Section II.F.2. and Section II.J.1.e.—or subject to permit revocation under Section II.J.1.b—if the source either did not comply with the regulations during construction or would not have qualified for the preconstruction activities undertaken. Because SC DHEC does not allow for the construction of process units, there are no increased emissions associated with any of the preconstruction 3 This memorandum is also included in the Docket for this proposed action. VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 activities allowed at Section II.A.1.c.i.– xvii. The gatekeeping applicability language at Section II.A.1.c. and major NSR applicability provisions at Regulation 61–62.5, Standard No. 7(a)(2) and Standard No. 7.1(a)(1), provide that no major sources or modifications may engage in the preconstruction activities allowed under Section II.A.1.c.i.–xvii. Additionally, SC DHEC does not allow synthetic minor sources to conduct the preconstruction activities. Finally, SC DHEC has legally enforceable procedures to prevent construction or modification of a source if it would violate SIP control strategies or interfere with attainment or maintenance of the NAAQS, as required by 40 CFR 51.160(b). The changes to South Carolina’s minor NSR program are not inconsistent with the requirements of the CAA and EPA’s regulations, and are therefore approvable as part of the SIP. EPA is therefore proposing to approve the aforementioned changes to subsection A. and the introductory portion of Section II pursuant to the CAA and 40 CFR 51.160–164. 2. Section II.B.—‘‘Exemptions From the Requirement To Obtain a Construction Permit’’ Regulation 61–62.1, Section II.B.— ‘‘Exemptions from the Requirement to Obtain a Construction Permit’’ specifies which types of minor sources are exempt from obtaining minor source construction permits. The October 1, 2007, submittal makes several changes to subsection II.B. as follows: (1) Renumbers existing Section II.F. to Section II.B. and modifies the title to clarify that the paragraph applies only to construction permits; (2) adds language specifying that future source modifications or new regulatory requirements may trigger the need to obtain a permit for exempted facilities; (3) clarifies that the exemption for boilers and space heaters applies to those firing virgin solid and liquid fuels; (4) adds an exemption for boilers and space heaters firing only virgin gas fuels rated 10 million British thermal units per hour or less; (5) modifies the number of hours for testing and maintenance for exempted emergency generators; (6) modifies subparagraph B.2.h. to exempt additional sources with emissions less than the threshold of 1 pound per hour (lb/hr) PTE of sulfur dioxide, nitrogen oxides, and carbon monoxide; (7) adds the requirement for SC DHEC to periodically publish a list of sources exempted from the construction permit requirement under subparagraphs B.2.a.–g.—and any other sources determined to qualify for permit PO 00000 Frm 00037 Fmt 4702 Sfmt 4702 39085 exemptions based on subparagraph B.2.h.—in the South Carolina State Register; (8) adds procedures for sources requesting exemption from obtaining a construction permit under paragraph B.2. or paragraph B.4.; (9) adds paragraph B.6. to provide that exemptions under Section II.B. do not relieve the owner or operator of any source from any obligation to comply with any other applicable requirements; and (10) makes other administrative changes and adds references throughout subsection B. The July 18, 2011, submittal makes subsequent revisions to clarify requirements and qualifications at Section II.B., as follows: (1) Adds language to subparagraph B.2.h. to require that emissions calculations or other information necessary to demonstrate a source qualifies for the exemption must be kept on site and provided to SC DHEC upon request; (2) revises language in paragraph B.3. to clarify that source types which are added to the list of exempted sources will be determined not to interfere with attainment or maintenance of any state or federal standard; (3) adds language stating that SC DHEC reserves the right to require a construction permit on a case-by-case basis, and that case-by-case determinations will consider, but not be limited to, ‘‘the nature and amount of the pollutants, location, proximity to residences and commercial establishments, etc.’’; and (4) makes administrative edits to existing language. Finally, the August 8, 2014, submittal makes additional changes to paragraph II.B., including: (1) Administrative edits to the title of the paragraph and to references and subparagraphs throughout; (2) revises the PTE criteria in subparagraph B.2.h. to a 5 ton per year (tpy) threshold rather than 1 lb/hr, and adds language to state that sources with higher PTE may be exempted under this subparagraph if they demonstrate that they are not subject to any applicable state or federal limits or requirements; (3) amends paragraph B.3. to include language asserting that SC DHEC may develop emission thresholds for exemption that are determined will not interfere with attainment or maintenance of state or federal standards to include in the list maintained pursuant to this paragraph, and that SC DHEC could be petitioned to consider adding additional sources to this list; and (4) adds paragraph B.5. stating that sources of volatile organic compounds (VOCs) with a PTE greater than the emission threshold listed in subparagraph B.2.h. may be exempted from the requirement to obtain a E:\FR\FM\17AUP1.SGM 17AUP1 sradovich on DSK3GMQ082PROD with PROPOSALS 39086 Federal Register / Vol. 82, No. 158 / Thursday, August 17, 2017 / Proposed Rules construction permit on a case-by-case basis, and that exempt sources may later be required to be included in construction or operating permits. Section 110(a)(2)(C) of the CAA requires that SIPs include a program for regulating the construction and modification of stationary sources as necessary to ensure that the NAAQS are maintained. Federal regulations at 40 CFR 51.160(e) require that states identify the types and sizes of sources subject to review and the basis for determining which sources are subject. Additionally, CAA section 110(l) provides that EPA shall not approve a revision to a plan if the revision would interfere with any applicable requirement concerning attainment and reasonable further progress (as defined in CAA section 171), or any other applicable requirement of the CAA. SC DHEC has determined that specific sources listed at paragraphs B.1. and B.2. do not require permits because their size is not such that they are expected to interfere with attainment or maintenance of state or federal standards, including reasonable further progress. SC DHEC’s December 30, 2016, letter provides additional clarification for certain changes made to Section II.B. Subparagraph B.2.f. extends the testing and maintenance operation threshold for exempting emergency generators from 250 hours to 500 hours per year. SC DHEC considered CAA section 110(l), and asserts that the state expects no increase in actual emissions as a result of raising this exemption threshold. SC DHEC explains that the 500 hours per year threshold is commonly used to determine the PTE for title V and other major source applicability determinations, consistent with an EPA guidance memorandum.4 These sources are still restricted to emergency conditions, meaning that other types of non-emergency activities—such as peak shaving— would not qualify for the exemption under paragraph II.B. Additionally, SC DHEC points to applicable federal requirements for emergency generators at 40 CFR part 63 at subpart ZZZZ and 40 CFR part 60 at subparts IIII and JJJJ to restrict non-emergency use of these sources to 100 hours per year. Therefore, this change to subparagraph B.2.f. will not result in any real increase in emissions and therefore will not affect the state’s ability to attain or maintain state or federal standards or 4 Seitz, John S. ‘‘Calculating Potential to Emit (PTE) for Emergency Generators.’’ Memorandum to Program Directors in EPA Regional Offices, Office of Air Quality Planning and Standards, Research Triangle Park, NC (September 6, 1995). VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 reasonable further progress. The State also has the discretion to define the scope of its minor NSR program pursuant to 40 CFR 51.160(e). SC DHEC in its letter also addresses changes made to subparagraph II.B.h. potentially allowing certain sources with PTE exceeding the thresholds of this subparagraph to be exempt from the requirement to obtain a construction permit. SC DHEC asserts that this provision is primarily intended to apply to sources with PTE only slightly above the thresholds in subparagraph II.B.h. SC DHEC notes the safeguards built into the language that sources subject to any applicable requirements are not exempt from obtaining construction permits. The letter then steps through an example of the process that small sources of VOC emissions would undergo, including an assessment of any potentially applicable requirements related to NAAQS, toxics, or hazardous air pollutants; consideration of the PTE relative to major source thresholds; and any other special considerations. SC DHEC determines the applicability of construction permits for these sources under close scrutiny on a case-by-case basis. This process in determining which types and sizes of sources need to undergo preconstruction review and permitting, afforded the State pursuant 40 CFR 51.160(e), is sufficient to protect the NAAQS and prevent interference with reasonable further progress, consistent with CAA sections 110(a)(2)(C) and 110(l). SC DHEC’s change to paragraph II.B.3. notes that SC DHEC may develop emission thresholds for exemptions that are not determined not to interfere with attainment or maintenance or any state or federal standard. EPA understands this language to reflect SC DHEC’s flexibility for determining which types and sizes of sources need to undergo preconstruction review and permitting pursuant 40 CFR 51.160(e), and understands that these thresholds would need to be in the SIP, similar to Subparagraph II.B.h. The compiled list is available on SC DHEC’s Web site.5 EPA preliminarily agrees that SC DHEC clearly lays out the types and sizes of sources of interest for preconstruction review, and also the reasonable process by which case-by-case determinations are made to exempt sources with emissions above the thresholds in subparagraph B.2.h., but less than any thresholds for other applicable requirements like major NSR. EPA also 5 The latest compiled list of exempted sources was updated as of December 2016: https:// www.scdhec.gov/Environment/docs/New Exemptions.pdf. PO 00000 Frm 00038 Fmt 4702 Sfmt 4702 preliminarily agrees that this portion of South Carolina’s minor NSR program does not interfere with attainment or maintenance of the NAAQS, reasonable further progress, or other applicable CAA requirements. Therefore, we are proposing to approve changes to the SIP made to Section II.B. pursuant to CAA sections 110(a)(2)(C) and 110(l), as well as 40 CFR 51.160–164. 3. Section II.C.—‘‘Construction Permit Applications’’ Regulation 61–62.1, Section II.C— ‘‘Construction Permit Applications,’’ specifies the requirements for sources applying for and obtaining construction permits. The October 1, 2007, submittal makes several changes to subsection C. as follows: (1) Renumbers former paragraph A.2. to standalone subsection C and changes the title to specify that the requirements apply to construction permit applications; (2) makes administrative edits, including renumbering; (3) adds paragraph C.3. to reference SC DHEC forms which were created to ease the permit application process; and (4) renumbers former subparagraphs B.2.a.–g. to C.3.a.–p., reformatting and clarifying what information may be required in addition to the SC DHEC forms, including more specific process, chemical, and emissions information used to determine PTE, an air quality analysis demonstrating protection of the NAAQS, and a regulatory applicability determination. The July 18, 2011, submittal further modifies Section II.C. at subparagraphs C.3.c.–d. to make administrative edits. South Carolina’s August 8, 2014, submittal makes additional administrative and clarifying edits. The January 20, 2016, submittal also makes minor administrative edits. Finally, the July 27, 2016, submittal makes one change to subparagraph C.2.m. to clarify that scale drawings of the facility must include buildings that might affect dispersion of emissions. EPA has reviewed the changes made to the construction permit application requirements and is proposing to approve them into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l). 4. Section II.D.—‘‘General Construction Permits’’ Regulation 61–62.1, Section II.D.— ‘‘General Construction Permits’’ provides regulations by which SC DHEC can issue general construction permits for similar sources. South Carolina’s October 1, 2007, submittal adds these provisions to the minor NSR program for construction permits to facilitate the permitting process for similar sources E:\FR\FM\17AUP1.SGM 17AUP1 Federal Register / Vol. 82, No. 158 / Thursday, August 17, 2017 / Proposed Rules sradovich on DSK3GMQ082PROD with PROPOSALS qualifying for and applying for coverage under permits with general terms and conditions. The purpose of this general permitting minor NSR program is to protect the NAAQS while simplifying the permitting process for similar sources. The general construction permits paragraph provides for the following: (1) General permits will incorporate all applicable requirements for construction of similar sources and identify the criteria by which sources can qualify for the permit; (2) sources can submit construction permit applications to SC DHEC that include requests for coverage under the general permit, and sources later determined not to qualify for the general permit are subject to enforcement; (3) approval to operate under a permit is a final permit action for the purposes of judicial review; (4) the permit application can deviate from the provisions of Section II.C. if enough information is included to determine the source’s qualification for the general permit; and (5) sources qualifying for general permits are able to apply for individual construction permits in lieu of coverage under the general permit. The August 8, 2014, submittal makes administrative and clarifying edits to subsection II.D. throughout. EPA has reviewed the changes made to the minor NSR permitting program and is proposing to approve them into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l). 6. Section II.E.—‘‘Synthetic Minor Construction Permits’’ Regulation 61–62.1, Section II.E.— ‘‘Synthetic Minor Construction Permits’’ specifies requirements for obtaining construction permits with federally enforceable emissions limits to restrict PTE for sources. South Carolina’s October 1, 2007, submittal revises the paragraph for synthetic minor sources as follows: (1) Renumbers subsection II.H. to subsection II.E.; (2) makes administrative and clarifying amendments to the title and throughout the paragraph to clearly indicate that this paragraph pertains to construction permits and to update references; (3) removes former subparagraphs II.2.c.–f. as these requirements are now redundant and covered by other portions of subsection E. or Section II; (4) adds paragraph E.3. to list required synthetic minor permit conditions; (5) adds administrative language to make applications for general synthetic minor construction permits consistent with other construction permit applications; and (6) adds paragraph E.5. to list additional requirements for synthetic minor construction permit applications VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 relative to other minor construction permit applications.

The July 27, 2016, submittal also makes administrative edits to subparagraph E.2.b. EPA has reviewed the changes made to the requirements covering synthetic minor construction permits and is proposing to approve them into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l), and 40 CFR 51.160–164. 7. Section II.F.—‘‘Operating Permits’’ Regulation 61–62.1, Section II.F.— ‘‘Operating Permits’’ specifies requirements for obtaining minor source operating permits. South Carolina’s October 1, 2007, submittal makes several changes to subsection II.F. to clarify and add requirements, including: (1) Renumbering subsection II.B. to II.F.; (2) adding paragraph F.1. to require sources to record the actual date of initial startup and submit it to SC DHEC; (3) adding paragraph F.2. to require certification that construction was completed in accordance with the specifications of the construction permit, to require any variances from the construction permit to be addressed, and to assert that construction variances which would trigger new requirements will be considered construction without a permit; (4) adding language to clarify that title V sources may comply with the Section II.F operating permit requirements by submitting a permit modification request under 61– 62.70.7(e) ; (5) adding language to clarify that the existing requirement to provide a written request to SC DHEC for a new or revised operating permit applies to minor sources and those major sources not yet covered by a title V permit; (6) adding subparagraph F.3.c. to specify that the written request for a new or revised operating permit must include a list of sources put into operation and the actual initial startup dates for those sources; (7) making other administrative edits throughout the paragraph; and (8) moving paragraph B.2. regarding permit renewals to a standalone subsection II.H. The August 8, 2014 and July 27, 2016, submittals make administrative changes to Section II.F.—‘‘Operating Permits.’’ EPA has reviewed the changes made to the existing SIP requirements for applying for an operating permit and is proposing to approve them into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l).

Section II.G.—‘‘Conditional Major Operating Permits’’ Regulation 61–62.1, Section II.G.— ‘‘Conditional Major Operating Permits’’ specifies requirements for obtaining operating permits with federally enforceable emissions limits to restrict PTE for sources. South Carolina’s October 1, 2007, submittal makes several changes to subsection II.G. to clarify applicability and requirements as follows: (1) Adds language to specify that paragraph II.G. applies to sources requesting federally enforceable limits to restrict PTE below major source thresholds; (2) adds language to specify that sources which received synthetic minor construction permits and that are not subject to title V will receive conditional major operating permits; (3) adds permit shield language to note that if the renewal request is submitted pursuant to paragraph II.H., conditional major sources can operate under the most recent conditional major permit until SC DHEC processes the renewal request; (4) adds language to note that the written request provided by new sources needs to include any additional information specified in subparagraph G.5.; (5) adds language and clarifies existing language to note that the permit conditions, including special conditions to verify compliance with operational and emissions limits, are located at subsection II.J.; (6) modifies existing language to specify additional requirements for conditional major operating permit applications only; (7) removes requirements pertaining to construction permit application requirements because subsections II.C. and II.E. otherwise cover these requirements; (8) removes requirements pertaining to standard operating permit applications because those are otherwise covered by subsection II.F.; (9) adds language to specify that the general information requirements in construction permit applications at paragraph C.3. also apply to conditional major operating permits; and (10) makes other administrative language changes throughout the paragraph. The July 18, 2011, August 8, 2014, and July 27, 2016, submittals make additional administrative changes to subsection II.G. EPA has reviewed the changes made to SC DHEC’s conditional major source program, which is a portion of the FESOP minor source program, and agrees that the revisions made to subsection II.G. clarify the requirements for obtaining conditional major operating permits. Further, EPA has determined that the conditional operating permit program remains consistent with the criteria for E:\FR\FM\17AUP1.SGM 17AUP1 39088 Federal Register / Vol. 82, No. 158 / Thursday, August 17, 2017 / Proposed Rules approving FESOP programs.6 Therefore, EPA is proposing to approve these changes into the SIP pursuant to CAA sections 110(a)(2)(C) and 110(l). sradovich on DSK3GMQ082PROD with PROPOSALS 9. Section II.H.—‘‘Operating Permit Renewal Request’’ Regulation 61–62.1, Section II.H.— ‘‘Operating Permit Renewal Request’’ specifies requirements for renewing operating permits for minor sources. South Carolina’s October 1, 2007, submittal makes several changes to subsection II.H. to clarify applicability and requirements as follows: (1) Renumbers former paragraph B.2. to make a standalone subsection at II.H.; (2) adds paragraph H.1. to clarify that operating permits must be renewed through a written request; (3) adds paragraph H.2. to clarify that subsection II.H does not apply to title V sources; (4) adds language to specify that sources must submit permit renewal requests no later than 90 days prior to expiration of the existing operating permit; (5) revises language to expand the type of information needed to verify special permit conditions; (6) adds language to require more specific information in the renewal request, including changes in the source information required for construction permits under paragraph C.3.; and (7) makes administrative language changes throughout the paragraph. The July 18, 2011, June 17, 2013, August 8, 2014, and July 27, 2016, submittals make several administrative edits and correct typographical errors throughout subsection II.H. EPA has reviewed the changes made to the operating permit renewal requirements and believes these changes are more specific and help to ensure SC DHEC has the best information possible when evaluating renewal requests. EPA has also preliminarily determined that the changes will not interfere with attainment or maintenance of the NAAQS, reasonable further progress, or other applicable CAA requirements. EPA is therefore proposing to approve these changes into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l). 10. Section II.I.—‘‘Registration Permits’’ Regulation 61–62.1, Section II.I.— ‘‘Registration Permits’’ provides regulations by which SC DHEC can issue registration permits, covering the construction and operation of similar sources. South Carolina’s October 1, 2007, submittal adds these provisions to the minor source construction and operating permitting program to 6 EPA approved SC DHEC’s FESOP program on December 11, 1995 (60 FR 63434). VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 facilitate the permitting process for similar true minor sources qualifying for and applying for coverage permits for specific source categories. The purpose of this registration permitting minor source program is to protect the NAAQS while simplifying the permitting process for similar true minor sources. The difference between registration permits and general construction permits or general operating permits is that this program develops permits for specific source categories exclusively for true minor sources. The October 1, 2007, submittal provides the following requirements for registration permits under paragraph II.I: (1) Registration permits will be developed by SC DHEC and will specify all applicable requirements for construction and operation of similar true minor sources; (2) registration permits will be developed only for true minor sources; (3) sources can submit applications for coverage by certifying qualification for, and agreeing to the conditions of, registration permits, and sources later determined not to qualify for the registration permit are subject to enforcement; (4) approval to operate under a permit is a final permit action for the purposes of judicial review; and (5) sources will adhere to general requirements under paragraph II.J.1., and any other special permit conditions necessary to verify compliance with operational and emission limits. The July 18, 2011, submittal makes subsequent changes to subsection II.I. as follows: (1) Makes administrative edits; (2) adds language to assert that regardless of qualification for registration permits, SC DHEC reserves the right to require construction and operating permits, as determined on a case-by-case basis; and (3) changes language to clarify that registration permits shall contain any applicable permit conditions under subsection II.J., rather than all permit conditions listed in paragraph II.J., as SC DHEC finds appropriate. The August 8, 2014, submittal includes other changes to paragraph II.I., including administrative edits throughout and adding language to assert that SC DHEC can reopen registration permits for cause or to include new standards or regulations that become applicable during the lifetime of the permit. The August 8, 2014, submittal also removes language at subparagraph I.1.a. requiring SC DHEC to provide notice and opportunity for public participation prior to developing new registration permits. However, the State withdrew this change from EPA’s consideration in a PO 00000 Frm 00040 Fmt 4702 Sfmt 4702 letter dated August 7, 2017.7 In the letter, SC DHEC explained that its intent in withdrawing the change was to require the Department to comply with the public participation procedures at subsection II.N. when developing registration permits. EPA has reviewed the changes made to the registration permit requirements, as clarified by the State’s August 7, 2017, letter, and is proposing to approve them into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l), and 40 CFR part 51, subpart I. 11. Section II.J.—‘‘Permit Conditions’’ Regulation 61–62.1, Section II.J.— ‘‘Permit Conditions’’ specifies required standard and special permit conditions. The October 1, 2007, submittal combines the standard and special permit conditions into a standalone section for required permit conditions. This submittal makes the following changes at paragraph J.: (1) Renumbers former subsection II.C. to II.J. and modifies the title to reflect that the subsection applies to all permit types; (2) requires sources to submit reports as specified in applicable permits, laws, regulations, or standards; (3) adds language to assert that a source may be subject to enforcement if it fails to construct in accordance with the application and any issued construction permit, or constructs without applying for approval; (4) adds language to clarify the time period over which construction permits are valid; (5) renumbers paragraph G.4. to paragraph J.2. and modifies the title to clarify that what follows are special permit conditions; (6) adds language stating that SC DHEC will require special permit conditions as it finds appropriate, such as operational limits or reporting and recordkeeping requirements; (7) removes former subparagraph G.4.g., which states conditions to limit PTE must be federally enforceable, because the State otherwise imposes this requirement for synthetic minor construction permits at subparagraph E.3. and conditional major operating permits at subparagraph G.5.; and (8) makes administrative language changes throughout subsection II.J. One change made to subparagraph J.1.d., formerly C.4., in the October 1, 2007, submittal regards when emissions reports need to be made. In the place of a specific quarterly timeframe, the change directs sources to comply with reporting requirements derived from applicable permit requirements, laws and regulations, or standards. There are no specific reporting requirements for 7 The August 7, 2017, letter has been included in the docket for this action. E:\FR\FM\17AUP1.SGM 17AUP1 Federal Register / Vol. 82, No. 158 / Thursday, August 17, 2017 / Proposed Rules minor sources specified in federal regulations at 40 CFR 51.160–164, so these reporting schedules can be developed as SC DHEC deems necessary.8 Moreover, subparagraph J.1.a. states that ‘‘[n]o applicable law, regulation or standard will be contravened.’’ Thus, if there is a prescriptive state or federal requirement for reporting of emissions that applies to any of these minor sources, the permits will set the necessary reporting schedule accordingly. Therefore, EPA has determined that this change does not interfere with attainment or maintenance of the NAAQS, reasonable further progress, or any other applicable CAA requirements. The July 18, 2011, submittal makes further revisions to subsection II.J., including: (1) Adding language stating that false information or misrepresentation in a permit application is grounds for permit revocation; (2) adding language stating that the issued construction or operating permit must be kept at the facility and that records must be kept as prescribed on site for at least five years; and (3) making administrative and clarifying edits. The August 8, 2014, submittal makes additional administrative changes. EPA has reviewed the changes to standard and special permit requirements for the minor source construction and operating permit program and is proposing to approve them into the SIP pursuant to CAA section 110(a)(2)(C) and 110(l). sradovich on DSK3GMQ082PROD with PROPOSALS 12. Section II.K.—‘‘Exceptions’’ Regulation 61–62.1, Section II.K.— ‘‘Exceptions’’ sets forth factors that SC DHEC shall consider in determining whether to impose alternative emissions limits, compliance schedules, or other restrictions. The October 1, 2007, submittal makes non-substantive changes to this subsection, including renumbering this existing subsection from II.D. to II.K., and making administrative language changes. EPA is therefore proposing to approve the aforementioned changes into the SIP pursuant to CAA sections 110(a)(2)(C) and 110(l). 13. Section II.M.—‘‘Transfer of Ownership/Operation’’ Regulation 61–62.1, Section II.M.— ‘‘Transfer of Ownership/Operation’’ specifies procedures for owners or operators of sources to undertake if the ownership or operation is transferred to another party. The October 1, 2007, 8 40 CFR 70.6 generally requires semiannual emissions and compliance reporting. VerDate Sep<11>2014 17:29 Aug 16, 2017 Jkt 241001 submittal makes minor changes to this regulation to renumber existing subsection II.E. to subsection II.M. and to add more specific requirements for the written request to transfer ownership or operation of a source. The August 8, 2014, submittal makes only administrative changes to language in this subsection. EPA has reviewed the changes to this existing portion of the minor source permitting regulations and is proposing to approve the aforementioned changes into the SIP pursuant to CAA section 110(a)(2)(C) and 110(l). 14. Section II.N.—‘‘Public Participation Procedures’’ Regulation 61–62.1, Section II.N.— ‘‘Public Participation Procedures,’’ specifies the public participation requirements for sources applying for and obtaining federally enforceable minor source construction and operating permits. The October 1, 2007, submittal makes several changes to subsection N. as follows: (1) Renumbers existing paragraph G.5. to create a standalone paragraph for public participation and clarify that these procedures can apply to other types of permit requests rather than only conditional major source operating permits; (2) adds language providing SC DHEC with discretion to require notice of permitting activity, even when not otherwise required by the State’s regulations; (3) adds language stating that SC DHEC can use means other than publishing in newspapers, the State Register, and mailing lists to notify the public of minor source permitting; and (5) makes administrative language edits for consistency. The July 18, 2011, submittal makes one clarifying edit to reflect that an approved construction permit is required prior to the commencement of construction. The August 8, 2014, submittal makes administrative and clarifying edits to subsection II.N., including: (1) Adding language to subparagraph N.1. to identify the SC DHEC Web site as another method of notifying the public of permitting activity; (2) reformatting and revising paragraph N.2. to list the required elements of the public notice; (3) revising language to identify how SC DHEC will address and record comments, and broadening the SC DHEC procedures to note that the State will respond to all comments rather than only those received in writing or at the public hearing; (4) removing language requiring SC DEHC to respond to all comments in writing; and (5) making administrative edits. PO 00000 Frm 00041 Fmt 4702 Sfmt 4702 39089 The changes in the October 1, 2007, submittal to allow for other methods of public notice, and in the August 8, 2014, submittal to explicitly list the SC DHEC Web site as a possible method of public notice are consistent with the minor source permitting regulations at 40 CFR 51.161. EPA has existing policy asserting that the public notice requirement for minor source permitting activities at 40 CFR 51.161(b)(3) is media-neutral, meaning that the public notice requirement can be met as long as the State interprets the method to be ‘‘prominent advertising.’’ 9 SC DHEC can therefore make use of its Web site, mailing lists, and other methods in lieu of publication in a newspaper. The provisions at subsection II.N. pertain only to minor sources, and any major source public notice requirements are contained in the major source PSD, NNSR, and title V regulations.10 EPA has reviewed the public notice requirements and preliminarily finds that the changes currently before the Agency are not inconsistent with the CAA and EPA’s implementing regulations, including the criteria for approving FESOP programs. See 54 FR 27274 (June 28, 1989). Therefore, EPA is proposing to approve the changes to the existing public notice requirements for the minor NSR and FESOP programs, pursuant to CAA section 110(a)(2)(C) and 40 CFR 51.160–164. 15. Section II.O.—‘‘Inspection and Entry’’ Regulation 61–62.1, Section II.O.— ‘‘Inspection and Entry,’’ specifies requirements to allow SC DHEC officials to enter and inspect facilities. South Carolina’s July 18, 2011, submittal adds these provisions to the minor source construction and operating permitting program to allow for verification of adherence to permit conditions. The August 8, 2014, submittal makes one additional administrative change to the introductory language at subsection II.O. The ability for SC DHEC to enter and inspect facilities enables the State to oversee the minor source permitting program, including assisting in potential enforcement actions. EPA is therefore proposing to approve this subsection 9 McCabe, Janet, ‘‘Minor New Source Review Program Public Notice Requirements under 40 CFR 51.161(b)(3),’’ Memorandum to Regional Administrators, Office of Air and Radiation, Washington, DC (April 17, 2012). 10 EPA published a final rule on October 18, 2016 (81 FR 71613) amending the public notice requirements for major source permitting programs to allow for other means of public notice, including Web sites. This proposed rulemaking only deals with changes to South Carolina’s minor source permitting regulations.

Specifically, EPA is proposing to approve the changes to S.C. Code Ann.

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. See 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 proposes to approve 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 Orders 12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011); • does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.); 11 See Section I and Section II.C. of this proposed rule for additional detail.

SUPPLEMENTARY INFORMATION:

I. What action is EPA proposing?

On October 1, 2007, July 18, 2011, June 17, 2013, August 8, 2014,
January 20, 2016, and July 27, 2016, SC DHEC submitted SIP revisions to
EPA for approval that involve changes to South Carolina's minor source
permitting regulations to clarify and streamline the State's federally-
approved preconstruction and operating permitting program. This program
requires minor stationary sources planning to construct or modify
sources of air pollutants to first obtain a construction permit and to
obtain and maintain operating permits in accordance with the South
Carolina Code of Regulations Annotated (S.C. Code Ann. Regs.) at
Regulation 61-62.1, Section II--``Permit Requirements.'' The portion of
the SIP-approved permitting program covering construction permits is
generally referred to as the minor source permitting program or the
minor NSR program to distinguish it from additional permitting
requirements for major sources of air pollutants.\1\ The portion of the
SIP-approved permitting program covering minor source operating permits
is referred to as the federally enforceable state operating permit
(FESOP) program. The changes made in these submittals clarify the
applicability, streamline the permitting process, provide more options
for the minor source permitting program, and generally reduce the
overall burden on the state permitting program and the regulated
community. The changes addressed in this proposed rulemaking also
correct typographical errors, make internal references consistent, and
recodify sections of the existing rules. In this action, EPA is
proposing to approve certain portions of these SIP submissions that
make changes to South Carolina's minor NSR regulations and FESOP
requirements.
---------------------------------------------------------------------------

\1\ EPA's regulations governing the implementation of NSR
permitting programs are contained in 40 CFR 51.160-.166; 52.21, .24;
and part 51, Appendix S. The CAA NSR program is composed of three
separate programs: prevention of significant deterioration (PSD),
nonattainment new source review (NNSR), and Minor NSR. PSD is
established in part C of title I of the CAA and applies to major
stationary sources in areas that meet the national ambient air
quality standards (NAAQS)--``attainment areas''--as well as areas
where there is insufficient information to determine if the area
meets the NAAQS--``unclassifiable areas.'' The NNSR program is
established in part D of title I of the CAA and applies to major
stationary sources in areas that are not in attainment of the
NAAQS--``nonattainment areas.'' The Minor NSR program applies to
stationary sources that do not require PSD or NNSR permits.
Together, these programs are referred to as the NSR programs.

II. Analysis of State's Submittal

A. Overview of Changes to Section II--``Permit Requirements''

South Carolina has a SIP-approved minor source permitting program
at Regulation 61-62.1, Section II--``Permit Requirements.'' These
regulations include requirements for obtaining preconstruction and
operating permits for different types of minor sources. The program
covers ``true minor'' sources, which have the potential to emit (PTE)
of certain pollutants below major sources thresholds for new sources
and modifications. The SIP-approved minor source permitting program
also includes provisions for issuing permits that establish federally
enforceable emission limits to restrict the PTE of certain pollutants
below major source and major modification applicability thresholds:
``synthetic minor'' permits establish these limits for sources
obtaining construction permits, and ``conditional major'' permits
establish these emission limits in the corresponding operating permits.
South Carolina initially revised its minor NSR and FESOP rules in the
October 1, 2007, submittal to clarify and streamline requirements for
obtaining minor source construction and operating permits. The July 18,
2011, June 17, 2013, August 8, 2014, January 20, 2016, and July 27,
2017, submittals make other clarifying and administrative changes,
which are discussed for each subsection of the regulation below.
EPA has reviewed the proposed changes to the minor source
construction and operating permitting regulations and preliminarily
finds them to be consistent with CAA sections 110(a)(2)(C) and 110(l),
EPA's minor NSR regulations found at 40 CFR 51.160--164, and the
criteria applicable to an approvable State FESOP program.

B. Analysis of Changes to Each Section

1. Section II.A.--``Construction Permits''
Regulation 61-62.1, Section II.A--``Construction Permits''
specifies applicability and certain requirements for obtaining permits
for sources seeking to construct or modify emissions units. The October
1, 2007, submittal makes several changes to paragraph A. as follows:
(1) Adds allowed preconstruction activities at subparagraph A.1.d. for
true minor sources (i.e., minor sources that are not synthetic minor
sources); (2) adds the requirement that written notification be
provided to the Department marking the commencement of construction and
initial startup; (3) adds language requiring compliance with all terms,
limits, and conditions of Department-issued construction permits; (4)
adds time constraints for the validity of issued construction permits;
and (5) removes the descriptions of permit application requirements
from former paragraph A.2. to create a standalone subsection C. for
construction permits, and to detail more specific requirements for
other types of permits in other paragraphs.
The July 18, 2011, submittal makes subsequent clarifying and
administrative changes to Section II.A., consolidating former
subparagraph A.1.a. and paragraph A.5. into an introductory paragraph
applicable to the entirety of Regulation 61-62.1, Section II. The
submittal also makes other renumbering and administrative edits to the
remaining subparagraphs.
The language moved to an introductory paragraph for Section II
states: (1) The regulation will not supersede any state or federal
requirements nor special permit conditions unless it imposes a more
restrictive limit; (2) sources must comply with all terms, conditions,
and limitations of any permit issued by SC DHEC for sources or
activities at its facility; and (3) a source's permit status may change
if new regulatory requirements become applicable. The effect of moving
this language from subsection A. is to clarify that it is applicable to
all of Section II--meaning it applies to any types of permits issued by
the SC DHEC rather than only construction permits.
The August 8, 2014, submittal further modifies Section II.A. by
making administrative edits and adding additional allowed
preconstruction activities for true minor sources at subparagraph
A.1.c, originally added in the October 1, 2007, submittal as
subparagraph A.1.d.
The revision to subparagraph A.1.c.--added to the Regulation as
A.1.d. in the October 1, 2007, submittal, renumbered in the July 18,
2011, submittal, and updated in the August 8, 2014, submittal--allows
certain preconstruction activities prior to obtaining a final
construction permit, provided that specific conditions are met. EPA has
preliminarily determined that the preconstruction activities provision
is consistent with the requirements of CAA sections 110(a)(2)(C) and
110(l), and federal regulations at 40 CFR 51.160--51.164.
Section 110(a)(2)(C) of the CAA requires that state SIPs include a
program for regulating the construction and modification of stationary
sources as necessary to ensure that the NAAQS are maintained. Federal
regulations at 40 CFR 51.160(b) require states to have legally
enforceable procedures to prevent construction or modification of a
source if it would violate any SIP control strategies or interfere with
attainment or maintenance of the NAAQS. Federal regulations limit the
types of allowed preconstruction activities for new and modified major
sources at 40 CFR 51.165(a)(1)(xv), 51.166(b)(11), and 52.21(b)(11)
and, as discussed below, South Carolina has adopted these provisions
into its SIP. But federal regulations do not impose a corresponding
limitation on preconstruction activities for minor sources. SC DHEC
provided additional clarification of its allowed minor source
preconstruction activities in a December 30, 2016, letter, which is
included in the Docket for this proposed action. In this letter, SC
DHEC first explains that ``[a]llowed preconstruction activities are
extremely limited in nature and do not include construction of that
actual process unit itself.'' The State also points to a requirement
under Section II.C.3.n. that sources applying for

[[Page 39085]]

construction permits demonstrate emissions will not interfere with
attainment or maintenance of the NAAQS. This requirement corresponds to
Section II.A.2. of the Regulation, which states that permits will not
be issued if emissions interfere with any state or federal standard.
SC DHEC also points to its memorandum regarding allowed
preconstruction activities for major sources prior to obtaining PSD
permits.\3\ SC DHEC notes that its minor source preconstruction
activities provisions mirror the federal limits on major source
preconstruction activities, with the exception of one additional
activity: Allowing a facility to pour concrete foundation prior to
obtaining a construction permit. This activity is only prohibited for
major sources or major modifications prior to obtaining a permit in
accordance with the definition of ``begin actual construction'' in the
federal PSD regulations at 40 CFR 51.166(b)(11) and 52.21(b)(11), and
the NNSR regulations at 51.165(a)(1)(xv). As SC DHEC explains in its
clarifying letter, Section II.A.1.c.--which specifies which sources may
engage in preconstruction activities--explicitly excludes ``sources not
requesting to use federally enforceable construction permit conditions
to limit potential to emit, sources not subject to regulations with
more stringent start of construction limitations, or sources not
otherwise exempt from permit requirements.'' In other words, the
regulation excludes, among other sources, major sources subject to PSD
regulations or CAA section 112 requirements for hazardous air
pollutants (i.e., major sources and modifications).
---------------------------------------------------------------------------

\3\ This memorandum is also included in the Docket for this
proposed action.
---------------------------------------------------------------------------

In its December 30, 2016 letter, SC DHEC references Section
II.A.1.d., which clearly states that the owners or operators of any
sources that would not qualify for the issuance of a construction
permit assume the financial risk of commencing the preconstruction
activities listed in Section II.A.1.c. SC DHEC also notes that a source
could be subject to an enforcement action under Section II.F.2. and
Section II.J.1.e.--or subject to permit revocation under Section
II.J.1.b--if the source either did not comply with the regulations
during construction or would not have qualified for the preconstruction
activities undertaken.
Because SC DHEC does not allow for the construction of process
units, there are no increased emissions associated with any of the
preconstruction activities allowed at Section II.A.1.c.i.-xvii. The
gatekeeping applicability language at Section II.A.1.c. and major NSR
applicability provisions at Regulation 61-62.5, Standard No. 7(a)(2)
and Standard No. 7.1(a)(1), provide that no major sources or
modifications may engage in the preconstruction activities allowed
under Section II.A.1.c.i.-xvii. Additionally, SC DHEC does not allow
synthetic minor sources to conduct the preconstruction activities.
Finally, SC DHEC has legally enforceable procedures to prevent
construction or modification of a source if it would violate SIP
control strategies or interfere with attainment or maintenance of the
NAAQS, as required by 40 CFR 51.160(b).
The changes to South Carolina's minor NSR program are not
inconsistent with the requirements of the CAA and EPA's regulations,
and are therefore approvable as part of the SIP. EPA is therefore
proposing to approve the aforementioned changes to subsection A. and
the introductory portion of Section II pursuant to the CAA and 40 CFR
51.160-164.
2. Section II.B.--``Exemptions From the Requirement To Obtain a
Construction Permit''
Regulation 61-62.1, Section II.B.--``Exemptions from the
Requirement to Obtain a Construction Permit'' specifies which types of
minor sources are exempt from obtaining minor source construction
permits. The October 1, 2007, submittal makes several changes to
subsection II.B. as follows: (1) Renumbers existing Section II.F. to
Section II.B. and modifies the title to clarify that the paragraph
applies only to construction permits; (2) adds language specifying that
future source modifications or new regulatory requirements may trigger
the need to obtain a permit for exempted facilities; (3) clarifies that
the exemption for boilers and space heaters applies to those firing
virgin solid and liquid fuels; (4) adds an exemption for boilers and
space heaters firing only virgin gas fuels rated 10 million British
thermal units per hour or less; (5) modifies the number of hours for
testing and maintenance for exempted emergency generators; (6) modifies
subparagraph B.2.h. to exempt additional sources with emissions less
than the threshold of 1 pound per hour (lb/hr) PTE of sulfur dioxide,
nitrogen oxides, and carbon monoxide; (7) adds the requirement for SC
DHEC to periodically publish a list of sources exempted from the
construction permit requirement under subparagraphs B.2.a.-g.--and any
other sources determined to qualify for permit exemptions based on
subparagraph B.2.h.--in the South Carolina State Register; (8) adds
procedures for sources requesting exemption from obtaining a
construction permit under paragraph B.2. or paragraph B.4.; (9) adds
paragraph B.6. to provide that exemptions under Section II.B. do not
relieve the owner or operator of any source from any obligation to
comply with any other applicable requirements; and (10) makes other
administrative changes and adds references throughout subsection B.
The July 18, 2011, submittal makes subsequent revisions to clarify
requirements and qualifications at Section II.B., as follows: (1) Adds
language to subparagraph B.2.h. to require that emissions calculations
or other information necessary to demonstrate a source qualifies for
the exemption must be kept on site and provided to SC DHEC upon
request; (2) revises language in paragraph B.3. to clarify that source
types which are added to the list of exempted sources will be
determined not to interfere with attainment or maintenance of any state
or federal standard; (3) adds language stating that SC DHEC reserves
the right to require a construction permit on a case-by-case basis, and
that case-by-case determinations will consider, but not be limited to,
``the nature and amount of the pollutants, location, proximity to
residences and commercial establishments, etc.''; and (4) makes
administrative edits to existing language.
Finally, the August 8, 2014, submittal makes additional changes to
paragraph II.B., including: (1) Administrative edits to the title of
the paragraph and to references and subparagraphs throughout; (2)
revises the PTE criteria in subparagraph B.2.h. to a 5 ton per year
(tpy) threshold rather than 1 lb/hr, and adds language to state that
sources with higher PTE may be exempted under this subparagraph if they
demonstrate that they are not subject to any applicable state or
federal limits or requirements; (3) amends paragraph B.3. to include
language asserting that SC DHEC may develop emission thresholds for
exemption that are determined will not interfere with attainment or
maintenance of state or federal standards to include in the list
maintained pursuant to this paragraph, and that SC DHEC could be
petitioned to consider adding additional sources to this list; and (4)
adds paragraph B.5. stating that sources of volatile organic compounds
(VOCs) with a PTE greater than the emission threshold listed in
subparagraph B.2.h. may be exempted from the requirement to obtain a

[[Page 39086]]

construction permit on a case-by-case basis, and that exempt sources
may later be required to be included in construction or operating
permits.
Section 110(a)(2)(C) of the CAA requires that SIPs include a
program for regulating the construction and modification of stationary
sources as necessary to ensure that the NAAQS are maintained. Federal
regulations at 40 CFR 51.160(e) require that states identify the types
and sizes of sources subject to review and the basis for determining
which sources are subject. Additionally, CAA section 110(l) provides
that EPA shall not approve a revision to a plan if the revision would
interfere with any applicable requirement concerning attainment and
reasonable further progress (as defined in CAA section 171), or any
other applicable requirement of the CAA. SC DHEC has determined that
specific sources listed at paragraphs B.1. and B.2. do not require
permits because their size is not such that they are expected to
interfere with attainment or maintenance of state or federal standards,
including reasonable further progress.
SC DHEC's December 30, 2016, letter provides additional
clarification for certain changes made to Section II.B. Subparagraph
B.2.f. extends the testing and maintenance operation threshold for
exempting emergency generators from 250 hours to 500 hours per year. SC
DHEC considered CAA section 110(l), and asserts that the state expects
no increase in actual emissions as a result of raising this exemption
threshold. SC DHEC explains that the 500 hours per year threshold is
commonly used to determine the PTE for title V and other major source
applicability determinations, consistent with an EPA guidance
memorandum.\4\ These sources are still restricted to emergency
conditions, meaning that other types of non-emergency activities--such
as peak shaving--would not qualify for the exemption under paragraph
II.B. Additionally, SC DHEC points to applicable federal requirements
for emergency generators at 40 CFR part 63 at subpart ZZZZ and 40 CFR
part 60 at subparts IIII and JJJJ to restrict non-emergency use of
these sources to 100 hours per year. Therefore, this change to
subparagraph B.2.f. will not result in any real increase in emissions
and therefore will not affect the state's ability to attain or maintain
state or federal standards or reasonable further progress. The State
also has the discretion to define the scope of its minor NSR program
pursuant to 40 CFR 51.160(e).

Emergency Generators.'' Memorandum to Program Directors in EPA

---------------------------------------------------------------------------

SC DHEC in its letter also addresses changes made to subparagraph
II.B.h. potentially allowing certain sources with PTE exceeding the
thresholds of this subparagraph to be exempt from the requirement to
obtain a construction permit. SC DHEC asserts that this provision is
primarily intended to apply to sources with PTE only slightly above the
thresholds in subparagraph II.B.h. SC DHEC notes the safeguards built
into the language that sources subject to any applicable requirements
are not exempt from obtaining construction permits. The letter then
steps through an example of the process that small sources of VOC
emissions would undergo, including an assessment of any potentially
applicable requirements related to NAAQS, toxics, or hazardous air
pollutants; consideration of the PTE relative to major source
thresholds; and any other special considerations. SC DHEC determines
the applicability of construction permits for these sources under close
scrutiny on a case-by-case basis. This process in determining which
types and sizes of sources need to undergo preconstruction review and
permitting, afforded the State pursuant 40 CFR 51.160(e), is sufficient
to protect the NAAQS and prevent interference with reasonable further
progress, consistent with CAA sections 110(a)(2)(C) and 110(l).
SC DHEC's change to paragraph II.B.3. notes that SC DHEC may
develop emission thresholds for exemptions that are not determined not
to interfere with attainment or maintenance or any state or federal
standard. EPA understands this language to reflect SC DHEC's
flexibility for determining which types and sizes of sources need to
undergo preconstruction review and permitting pursuant 40 CFR
51.160(e), and understands that these thresholds would need to be in
the SIP, similar to Subparagraph II.B.h. The compiled list is available
on SC DHEC's Web site.\5\ EPA preliminarily agrees that SC DHEC clearly
lays out the types and sizes of sources of interest for preconstruction
review, and also the reasonable process by which case-by-case
determinations are made to exempt sources with emissions above the
thresholds in subparagraph B.2.h., but less than any thresholds for
other applicable requirements like major NSR. EPA also preliminarily
agrees that this portion of South Carolina's minor NSR program does not
interfere with attainment or maintenance of the NAAQS, reasonable
further progress, or other applicable CAA requirements. Therefore, we
are proposing to approve changes to the SIP made to Section II.B.
pursuant to CAA sections 110(a)(2)(C) and 110(l), as well as 40 CFR
51.160-164.
---------------------------------------------------------------------------

\5\ The latest compiled list of exempted sources was updated as
of December 2016: https://www.scdhec.gov/Environment/docs/NewExemptions.pdf.
---------------------------------------------------------------------------

3. Section II.C.--``Construction Permit Applications''
Regulation 61-62.1, Section II.C--``Construction Permit
Applications,'' specifies the requirements for sources applying for and
obtaining construction permits. The October 1, 2007, submittal makes
several changes to subsection C. as follows: (1) Renumbers former
paragraph A.2. to standalone subsection C and changes the title to
specify that the requirements apply to construction permit
applications; (2) makes administrative edits, including renumbering;
(3) adds paragraph C.3. to reference SC DHEC forms which were created
to ease the permit application process; and (4) renumbers former
subparagraphs B.2.a.-g. to C.3.a.-p., reformatting and clarifying what
information may be required in addition to the SC DHEC forms, including
more specific process, chemical, and emissions information used to
determine PTE, an air quality analysis demonstrating protection of the
NAAQS, and a regulatory applicability determination.
The July 18, 2011, submittal further modifies Section II.C. at
subparagraphs C.3.c.-d. to make administrative edits. South Carolina's
August 8, 2014, submittal makes additional administrative and
clarifying edits. The January 20, 2016, submittal also makes minor
administrative edits. Finally, the July 27, 2016, submittal makes one
change to subparagraph C.2.m. to clarify that scale drawings of the
facility must include buildings that might affect dispersion of
emissions.
EPA has reviewed the changes made to the construction permit
application requirements and is proposing to approve them into the SIP,
pursuant to CAA sections 110(a)(2)(C) and 110(l).
4. Section II.D.--``General Construction Permits''
Regulation 61-62.1, Section II.D.--``General Construction Permits''
provides regulations by which SC DHEC can issue general construction
permits for similar sources. South Carolina's October 1, 2007,
submittal adds these provisions to the minor NSR program for
construction permits to facilitate the permitting process for similar
sources

[[Page 39087]]

qualifying for and applying for coverage under permits with general
terms and conditions. The purpose of this general permitting minor NSR
program is to protect the NAAQS while simplifying the permitting
process for similar sources. The general construction permits paragraph
provides for the following: (1) General permits will incorporate all
applicable requirements for construction of similar sources and
identify the criteria by which sources can qualify for the permit; (2)
sources can submit construction permit applications to SC DHEC that
include requests for coverage under the general permit, and sources
later determined not to qualify for the general permit are subject to
enforcement; (3) approval to operate under a permit is a final permit
action for the purposes of judicial review; (4) the permit application
can deviate from the provisions of Section II.C. if enough information
is included to determine the source's qualification for the general
permit; and (5) sources qualifying for general permits are able to
apply for individual construction permits in lieu of coverage under the
general permit.
The August 8, 2014, submittal makes administrative and clarifying
edits to subsection II.D. throughout. EPA has reviewed the changes made
to the minor NSR permitting program and is proposing to approve them
into the SIP, pursuant to CAA sections 110(a)(2)(C) and 110(l).
6. Section II.E.--``Synthetic Minor Construction Permits''
Regulation 61-62.1, Section II.E.--``Synthetic Minor Construction
Permits'' specifies requirements for obtaining construction permits
with federally enforceable emissions limits to restrict PTE for
sources. South Carolina's October 1, 2007, submittal revises the
paragraph for synthetic minor sources as follows: (1) Renumbers
subsection II.H. to subsection II.E.; (2) makes administrative and
clarifying amendments to the title and throughout the paragraph to
clearly indicate that this paragraph pertains to construction permits
and to update references; (3) removes former subparagraphs II.2.c.-f.
as these requirements are now redundant and covered by other portions
of subsection E. or Section II; (4) adds paragraph E.3. to list
required synthetic minor permit conditions; (5) adds administrative
language to make applications for general synthetic minor construction
permits consistent with other construction permit applications; and (6)
adds paragraph E.5. to list additional requirements for synthetic minor
construction permit applications relative to other minor construction
permit applications.
The August 8, 2014, submittal makes changes to subsection II.E. to
update administrative language and references throughout the paragraph.
The July 27, 2016, submittal also makes administrative edits to
subparagraph E.2.b. EPA has reviewed the changes made to the
requirements covering synthetic minor construction permits and is
proposing to approve them into the SIP, pursuant to CAA sections
110(a)(2)(C) and 110(l), and 40 CFR 51.160-164.
7. Section II.F.--``Operating Permits''
Regulation 61-62.1, Section II.F.--``Operating Permits'' specifies
requirements for obtaining minor source operating permits. South
Carolina's October 1, 2007, submittal makes several changes to
subsection II.F. to clarify and add requirements, including: (1)
Renumbering subsection II.B. to II.F.; (2) adding paragraph F.1. to
require sources to record the actual date of initial startup and submit
it to SC DHEC; (3) adding paragraph F.2. to require certification that
construction was completed in accordance with the specifications of the
construction permit, to require any variances from the construction
permit to be addressed, and to assert that construction variances which
would trigger new requirements will be considered construction without
a permit; (4) adding language to clarify that title V sources may
comply with the Section II.F operating permit requirements by
submitting a permit modification request under 61-62.70.7(e) ; (5)
adding language to clarify that the existing requirement to provide a
written request to SC DHEC for a new or revised operating permit
applies to minor sources and those major sources not yet covered by a
title V permit; (6) adding subparagraph F.3.c. to specify that the
written request for a new or revised operating permit must include a
list of sources put into operation and the actual initial startup dates
for those sources; (7) making other administrative edits throughout the
paragraph; and (8) moving paragraph B.2. regarding permit renewals to a
standalone subsection II.H.
The August 8, 2014 and July 27, 2016, submittals make
administrative changes to Section II.F.--``Operating Permits.'' EPA has
reviewed the changes made to the existing SIP requirements for applying
for an operating permit and is proposing to approve them into the SIP,
pursuant to CAA sections 110(a)(2)(C) and 110(l).
38. Section II.G.--``Conditional Major Operating Permits''
Regulation 61-62.1, Section II.G.--``Conditional Major Operating
Permits'' specifies requirements for obtaining operating permits with
federally enforceable emissions limits to restrict PTE for sources.
South Carolina's October 1, 2007, submittal makes several changes to
subsection II.G. to clarify applicability and requirements as follows:
(1) Adds language to specify that paragraph II.G. applies to sources
requesting federally enforceable limits to restrict PTE below major
source thresholds; (2) adds language to specify that sources which
received synthetic minor construction permits and that are not subject
to title V will receive conditional major operating permits; (3) adds
permit shield language to note that if the renewal request is submitted
pursuant to paragraph II.H., conditional major sources can operate
under the most recent conditional major permit until SC DHEC processes
the renewal request; (4) adds language to note that the written request
provided by new sources needs to include any additional information
specified in subparagraph G.5.; (5) adds language and clarifies
existing language to note that the permit conditions, including special
conditions to verify compliance with operational and emissions limits,
are located at subsection II.J.; (6) modifies existing language to
specify additional requirements for conditional major operating permit
applications only; (7) removes requirements pertaining to construction
permit application requirements because subsections II.C. and II.E.
otherwise cover these requirements; (8) removes requirements pertaining
to standard operating permit applications because those are otherwise
covered by subsection II.F.; (9) adds language to specify that the
general information requirements in construction permit applications at
paragraph C.3. also apply to conditional major operating permits; and
(10) makes other administrative language changes throughout the
paragraph.
The July 18, 2011, August 8, 2014, and July 27, 2016, submittals
make additional administrative changes to subsection II.G. EPA has
reviewed the changes made to SC DHEC's conditional major source
program, which is a portion of the FESOP minor source program, and
agrees that the revisions made to subsection II.G. clarify the
requirements for obtaining conditional major operating permits.
Further, EPA has determined that the conditional operating permit
program remains consistent with the criteria for

[[Page 39088]]

approving FESOP programs.\6\ Therefore, EPA is proposing to approve
these changes into the SIP pursuant to CAA sections 110(a)(2)(C) and
110(l).
---------------------------------------------------------------------------

\6\ EPA approved SC DHEC's FESOP program on December 11, 1995
(60 FR 63434).
---------------------------------------------------------------------------

9. Section II.H.--``Operating Permit Renewal Request''
Regulation 61-62.1, Section II.H.--``Operating Permit Renewal
Request'' specifies requirements for renewing operating permits for
minor sources. South Carolina's October 1, 2007, submittal makes
several changes to subsection II.H. to clarify applicability and
requirements as follows: (1) Renumbers former paragraph B.2. to make a
standalone subsection at II.H.; (2) adds paragraph H.1. to clarify that
operating permits must be renewed through a written request; (3) adds
paragraph H.2. to clarify that subsection II.H does not apply to title
V sources; (4) adds language to specify that sources must submit permit
renewal requests no later than 90 days prior to expiration of the
existing operating permit; (5) revises language to expand the type of
information needed to verify special permit conditions; (6) adds
language to require more specific information in the renewal request,
including changes in the source information required for construction
permits under paragraph C.3.; and (7) makes administrative language
changes throughout the paragraph.
The July 18, 2011, June 17, 2013, August 8, 2014, and July 27,
2016, submittals make several administrative edits and correct
typographical errors throughout subsection II.H. EPA has reviewed the
changes made to the operating permit renewal requirements and believes
these changes are more specific and help to ensure SC DHEC has the best
information possible when evaluating renewal requests. EPA has also
preliminarily determined that the changes will not interfere with
attainment or maintenance of the NAAQS, reasonable further progress, or
other applicable CAA requirements. EPA is therefore proposing to
approve these changes into the SIP, pursuant to CAA sections
110(a)(2)(C) and 110(l).
10. Section II.I.--``Registration Permits''
Regulation 61-62.1, Section II.I.--``Registration Permits''
provides regulations by which SC DHEC can issue registration permits,
covering the construction and operation of similar sources. South
Carolina's October 1, 2007, submittal adds these provisions to the
minor source construction and operating permitting program to
facilitate the permitting process for similar true minor sources
qualifying for and applying for coverage permits for specific source
categories. The purpose of this registration permitting minor source
program is to protect the NAAQS while simplifying the permitting
process for similar true minor sources. The difference between
registration permits and general construction permits or general
operating permits is that this program develops permits for specific
source categories exclusively for true minor sources.
The October 1, 2007, submittal provides the following requirements
for registration permits under paragraph II.I: (1) Registration permits
will be developed by SC DHEC and will specify all applicable
requirements for construction and operation of similar true minor
sources; (2) registration permits will be developed only for true minor
sources; (3) sources can submit applications for coverage by certifying
qualification for, and agreeing to the conditions of, registration
permits, and sources later determined not to qualify for the
registration permit are subject to enforcement; (4) approval to operate
under a permit is a final permit action for the purposes of judicial
review; and (5) sources will adhere to general requirements under
paragraph II.J.1., and any other special permit conditions necessary to
verify compliance with operational and emission limits.
The July 18, 2011, submittal makes subsequent changes to subsection
II.I. as follows: (1) Makes administrative edits; (2) adds language to
assert that regardless of qualification for registration permits, SC
DHEC reserves the right to require construction and operating permits,
as determined on a case-by-case basis; and (3) changes language to
clarify that registration permits shall contain any applicable permit
conditions under subsection II.J., rather than all permit conditions
listed in paragraph II.J., as SC DHEC finds appropriate.
The August 8, 2014, submittal includes other changes to paragraph
II.I., including administrative edits throughout and adding language to
assert that SC DHEC can reopen registration permits for cause or to
include new standards or regulations that become applicable during the
lifetime of the permit. The August 8, 2014, submittal also removes
language at subparagraph I.1.a. requiring SC DHEC to provide notice and
opportunity for public participation prior to developing new
registration permits. However, the State withdrew this change from
EPA's consideration in a letter dated August 7, 2017.\7\ In the letter,
SC DHEC explained that its intent in withdrawing the change was to
require the Department to comply with the public participation
procedures at subsection II.N. when developing registration permits.
---------------------------------------------------------------------------

\7\ The August 7, 2017, letter has been included in the docket
for this action.
---------------------------------------------------------------------------

EPA has reviewed the changes made to the registration permit
requirements, as clarified by the State's August 7, 2017, letter, and
is proposing to approve them into the SIP, pursuant to CAA sections
110(a)(2)(C) and 110(l), and 40 CFR part 51, subpart I.
11. Section II.J.--``Permit Conditions''
Regulation 61-62.1, Section II.J.--``Permit Conditions'' specifies
required standard and special permit conditions. The October 1, 2007,
submittal combines the standard and special permit conditions into a
standalone section for required permit conditions. This submittal makes
the following changes at paragraph J.: (1) Renumbers former subsection
II.C. to II.J. and modifies the title to reflect that the subsection
applies to all permit types; (2) requires sources to submit reports as
specified in applicable permits, laws, regulations, or standards; (3)
adds language to assert that a source may be subject to enforcement if
it fails to construct in accordance with the application and any issued
construction permit, or constructs without applying for approval; (4)
adds language to clarify the time period over which construction
permits are valid; (5) renumbers paragraph G.4. to paragraph J.2. and
modifies the title to clarify that what follows are special permit
conditions; (6) adds language stating that SC DHEC will require special
permit conditions as it finds appropriate, such as operational limits
or reporting and recordkeeping requirements; (7) removes former
subparagraph G.4.g., which states conditions to limit PTE must be
federally enforceable, because the State otherwise imposes this
requirement for synthetic minor construction permits at subparagraph
E.3. and conditional major operating permits at subparagraph G.5.; and
(8) makes administrative language changes throughout subsection II.J.
One change made to subparagraph J.1.d., formerly C.4., in the
October 1, 2007, submittal regards when emissions reports need to be
made. In the place of a specific quarterly timeframe, the change
directs sources to comply with reporting requirements derived from
applicable permit requirements, laws and regulations, or standards.
There are no specific reporting requirements for

[[Page 39089]]

minor sources specified in federal regulations at 40 CFR 51.160-164, so
these reporting schedules can be developed as SC DHEC deems
necessary.\8\ Moreover, subparagraph J.1.a. states that ``[n]o
applicable law, regulation or standard will be contravened.'' Thus, if
there is a prescriptive state or federal requirement for reporting of
emissions that applies to any of these minor sources, the permits will
set the necessary reporting schedule accordingly. Therefore, EPA has
determined that this change does not interfere with attainment or
maintenance of the NAAQS, reasonable further progress, or any other
applicable CAA requirements.
---------------------------------------------------------------------------

\8\ 40 CFR 70.6 generally requires semiannual emissions and
compliance reporting.
---------------------------------------------------------------------------

The July 18, 2011, submittal makes further revisions to subsection
II.J., including: (1) Adding language stating that false information or
misrepresentation in a permit application is grounds for permit
revocation; (2) adding language stating that the issued construction or
operating permit must be kept at the facility and that records must be
kept as prescribed on site for at least five years; and (3) making
administrative and clarifying edits. The August 8, 2014, submittal
makes additional administrative changes.
EPA has reviewed the changes to standard and special permit
requirements for the minor source construction and operating permit
program and is proposing to approve them into the SIP pursuant to CAA
section 110(a)(2)(C) and 110(l).
12. Section II.K.--``Exceptions''
Regulation 61-62.1, Section II.K.--``Exceptions'' sets forth
factors that SC DHEC shall consider in determining whether to impose
alternative emissions limits, compliance schedules, or other
restrictions. The October 1, 2007, submittal makes non-substantive
changes to this subsection, including renumbering this existing
subsection from II.D. to II.K., and making administrative language
changes. EPA is therefore proposing to approve the aforementioned
changes into the SIP pursuant to CAA sections 110(a)(2)(C) and 110(l).
13. Section II.M.--``Transfer of Ownership/Operation''
Regulation 61-62.1, Section II.M.--``Transfer of Ownership/
Operation'' specifies procedures for owners or operators of sources to
undertake if the ownership or operation is transferred to another
party. The October 1, 2007, submittal makes minor changes to this
regulation to renumber existing subsection II.E. to subsection II.M.
and to add more specific requirements for the written request to
transfer ownership or operation of a source. The August 8, 2014,
submittal makes only administrative changes to language in this
subsection.
EPA has reviewed the changes to this existing portion of the minor
source permitting regulations and is proposing to approve the
aforementioned changes into the SIP pursuant to CAA section
110(a)(2)(C) and 110(l).
14. Section II.N.--``Public Participation Procedures''
Regulation 61-62.1, Section II.N.--``Public Participation
Procedures,'' specifies the public participation requirements for
sources applying for and obtaining federally enforceable minor source
construction and operating permits. The October 1, 2007, submittal
makes several changes to subsection N. as follows: (1) Renumbers
existing paragraph G.5. to create a standalone paragraph for public
participation and clarify that these procedures can apply to other
types of permit requests rather than only conditional major source
operating permits; (2) adds language providing SC DHEC with discretion
to require notice of permitting activity, even when not otherwise
required by the State's regulations; (3) adds language stating that SC
DHEC can use means other than publishing in newspapers, the State
Register, and mailing lists to notify the public of minor source
permitting; and (5) makes administrative language edits for
consistency.
The July 18, 2011, submittal makes one clarifying edit to reflect
that an approved construction permit is required prior to the
commencement of construction. The August 8, 2014, submittal makes
administrative and clarifying edits to subsection II.N., including: (1)
Adding language to subparagraph N.1. to identify the SC DHEC Web site
as another method of notifying the public of permitting activity; (2)
reformatting and revising paragraph N.2. to list the required elements
of the public notice; (3) revising language to identify how SC DHEC
will address and record comments, and broadening the SC DHEC procedures
to note that the State will respond to all comments rather than only
those received in writing or at the public hearing; (4) removing
language requiring SC DEHC to respond to all comments in writing; and
(5) making administrative edits.
The changes in the October 1, 2007, submittal to allow for other
methods of public notice, and in the August 8, 2014, submittal to
explicitly list the SC DHEC Web site as a possible method of public
notice are consistent with the minor source permitting regulations at
40 CFR 51.161. EPA has existing policy asserting that the public notice
requirement for minor source permitting activities at 40 CFR
51.161(b)(3) is media-neutral, meaning that the public notice
requirement can be met as long as the State interprets the method to be
``prominent advertising.'' \9\ SC DHEC can therefore make use of its
Web site, mailing lists, and other methods in lieu of publication in a
newspaper. The provisions at subsection II.N. pertain only to minor
sources, and any major source public notice requirements are contained
in the major source PSD, NNSR, and title V regulations.\10\
---------------------------------------------------------------------------

\9\ McCabe, Janet, ``Minor New Source Review Program Public
Notice Requirements under 40 CFR 51.161(b)(3),'' Memorandum to
Regional Administrators, Office of Air and Radiation, Washington, DC
(April 17, 2012).
\10\ EPA published a final rule on October 18, 2016 (81 FR
71613) amending the public notice requirements for major source
permitting programs to allow for other means of public notice,
including Web sites. This proposed rulemaking only deals with
changes to South Carolina's minor source permitting regulations.
---------------------------------------------------------------------------

EPA has reviewed the public notice requirements and preliminarily
finds that the changes currently before the Agency are not inconsistent
with the CAA and EPA's implementing regulations, including the criteria
for approving FESOP programs. See 54 FR 27274 (June 28, 1989).
Therefore, EPA is proposing to approve the changes to the existing
public notice requirements for the minor NSR and FESOP programs,
pursuant to CAA section 110(a)(2)(C) and 40 CFR 51.160-164.
15. Section II.O.--``Inspection and Entry''
Regulation 61-62.1, Section II.O.--``Inspection and Entry,''
specifies requirements to allow SC DHEC officials to enter and inspect
facilities. South Carolina's July 18, 2011, submittal adds these
provisions to the minor source construction and operating permitting
program to allow for verification of adherence to permit conditions.
The August 8, 2014, submittal makes one additional administrative
change to the introductory language at subsection II.O. The ability for
SC DHEC to enter and inspect facilities enables the State to oversee
the minor source permitting program, including assisting in potential
enforcement actions. EPA is therefore proposing to approve this
subsection

[[Page 39090]]

and its updated provisions into the SIP, pursuant to CAA section
110(a)(2)(C).

IV. Incorporation by Reference

In this rule, EPA is proposing to include in a final EPA rule
regulatory text that includes incorporation by reference. In accordance
with the requirements of 1 CFR 51.5, EPA is proposing to incorporate by
reference South Carolina Regulation 61-62.1, Section II--``Permit
Requirements,'' effective June 24, 2016,\11\ which revises the
federally enforceable minor source construction and operating permit
program. EPA has made, and will continue to make, these materials
generally available through www.regulations.gov and/or at the EPA
Region 4 office (please contact the person identified in the FOR
FURTHER INFORMATION CONTACT section of this preamble for more
information).
---------------------------------------------------------------------------

\11\ See Section I and Section II.C. of this proposed rule for
additional detail.
---------------------------------------------------------------------------

V. Proposed Action

EPA is proposing to approve portions of revisions to the South
Carolina SIP submitted by SC DHEC to EPA on October 1, 2007, July 18,
2011, June 17, 2013, August 8, 2014, January 20, 2016, and July 27,
2016. Specifically, EPA is proposing to approve the changes to S.C.
Code Ann. Regs. 61-62.1, Section II--``Permit Requirements,'' as
discussed above, pursuant to CAA section 110(a)(2)(C), section 110(l),
and 40 CFR 51.160--164.

VI. 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. See 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 proposes to approve 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 Orders 12866 (58
FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 2011);
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 (Public Law 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 proposed rule for South Carolina does not have Tribal
implications as specified by Executive Order 13175 (65 FR 67249,
November 9, 2000), because it does not have substantial direct effects
on an Indian Tribe. The Catawba Indian Nation Reservation is located
within the state of South Carolina. Pursuant to the Catawba Indian
Claims Settlement Act, S.C. Code Ann. 27-16-120, ``all state and local
environmental laws and regulations apply to the [Catawba Indian Nation]
and Reservation and are fully enforceable by all relevant state and
local agencies and authorities.'' EPA notes this action will not impose
substantial direct costs on Tribal governments or preempt Tribal law.
