Air Plan Approval; Ohio; Ohio Less Than 10 TPY BAT Exemption

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The Environmental Protection Agency (EPA) is proposing to approve, under the Clean Air Act (CAA), revisions to Ohio's State Implementation Plan (SIP) as requested by the Ohio Environmental Protection Agency (OEPA) on May 22, 2018. OEPA has submitted, for approval, revisions that exempt sources that emit less than 10 tons per year (tpy) from the need to employ Best Available Technology (BAT). EPA is proposing to approve these revisions because they are consistent with Federal regulations governing state permit programs.

DATES: Comments must be received on or before December 14, 2018.

  6. What revisions did OEPA submit?

    On May 22, 2018, OEPA submitted a SIP revision to Ohio Administrative Code (OAC) rule 3745-31-05(A)(3)(a)(ii), which is its BAT rule. This revision exempts the smaller emitting sources, those that emit less than 10 tpy of each criteria pollutant, from the need to employ BAT. OEPA's less than 10 tpy BAT exemption is currently in OEPA's OAC 3745-31-05(A)(3)(a)(ii) and reads: ``BAT is not required if the air contaminant source was installed or modified on or after August 3, 2006 and has the potential to emit (PTE), taking into account air pollution controls installed on the source, less than ten tons per year of emissions of an air contaminant or precursor of an air contaminant for which a national ambient air quality standard has been adopted under the Clean Air Act.''

    Ohio's Federally approved construction program, OAC 3745-31 (``Permits to Install New Sources of Pollution'') provides the authority for OEPA to issue Permits to Install (PTI) to new sources of air pollution or modifications to existing sources of air pollution. For attainment areas, the program was conditionally approved into Ohio's SIP on October 10, 2001 (66 FR 51570), and fully approved on January 22, 2003 (68 FR 2909). For nonattainment areas, the program was fully approved on January 10, 2002 (68 FR 1366). On February 20, 2013, OEPA's SIP was revised (78 FR 28547) to combine the PTI and Permit to Operate (PTO) programs into a single Permit to Install and Operate (PTIO) program so that a minor source not subject to title V of the Clean Air Act in Ohio would be issued a single PTIO instead of a PTI and a PTO permit.

    On August 3, 2006, the Ohio General Assembly passed Senate Bill 265 (SB 265) which required OEPA to modify several of its BAT rules. OEPA's BAT is an air permitting mechanism to help control emissions in minor air permits. BAT can be any combination of work practices, air pollution control devices, raw material specifications, throughput limitations, source design characteristics, and OEPA does an evaluation of the annualized cost per ton of air pollutant removed when determining BAT. One of the changes implemented was the less than 10 tpy BAT exemption. To implement the SB 265 changes, OEPA adopted revisions under OAC Chapter 3745-31-05(A)(3)(b) on November 20, 2006, which became effective on December 1, 2006. On January 18, 2008, OEPA requested that EPA approve this rule language as a revision to Ohio's SIP. EPA responded with a June 5, 2008 letter to OEPA indicating that the request was incomplete due to a lack of a CAA section 110(l) demonstration, thus returning the request back to OEPA. On June 2, 2008, OEPA moved the language in OAC rule 3745-31-05 from paragraph (A)(3)(b) to (A)(3)(a)(ii) which became effective at the state level on June 30, 2008. The rule language contained in OAC rule 3745-31-

    05(A)(3)(a)(ii) was carried over in OAC rule 3745-31-05, which was adopted on April 20, 2016, and became effective at the state level as of May 1, 2016, and is what OEPA is now requesting for EPA approval as a revision to its SIP. EPA considered this May 22, 2018 submittal to be complete.

  7. Do the revisions comply with section 110(l) of the Clean Air Act?

    OEPA's May 22, 2018 SIP revision submittal included a 110(l) demonstration. This demonstration included an extensive analysis to show the impact that the less than 10 tpy BAT exemption would have on emissions. This analysis evaluated over 400 permits, representing more than 80

    Page 56776

    source classification codes and 36 different types of categories of sources. Each criteria pollutant was evaluated and then a comparison was made between the emission limit that would occur if BAT applied and if BAT did not apply to the less than 10 tpy sources. The analysis concludes that there would be a negligible increase in emissions due to the less than 10 tpy BAT exemption.

    The 110(l) demonstration included a quantitative and qualitative analysis. The analysis estimated an emission increase of 36.89 tpy of volatile organic compounds (VOC) emissions in attainment areas and nonattainment areas, combined, when applying the less than 10 tpy BAT exemption compared to BAT-based emissions. That increase in VOC emissions represented a very small amount (0.12%) of the total actual point source VOC emissions reported for that year, 2010 in Ohio.

    The 110(l) analysis estimated the VOC emission increases in the Ohio nonattainment areas combined, as well as to each of the three Ohio ozone nonattainment areas (Cleveland, Cincinnati, Columbus). This analysis links the estimated VOC increases to each of the Ohio ozone nonattainment areas and demonstrates that each nonattainment area will not be negatively impacted by the estimated increase in emissions. The analysis showed an estimated increase of 25.53 tpy of VOC in Ohio nonattainment areas which represented 0.2% of the 2010 total VOC emissions in Ohio. OEPA's analysis also quantified the estimated VOC increases in the three Ohio nonattainment areas: 18.65 tpy in the Cincinnati area, 4.88 tpy in the Cleveland/Akron/Lorain area, and 0 tpy in the Columbus area. OEPA's analysis further broke out the 18.65 tpy Cincinnati nonattainment area VOC emission increase to the following two areas: 13 tpy increase in Hamilton County, and 5.6 tpy in Butler County.

    To address the VOC emission increases in the Cincinnati and Cleveland nonattainment areas, OEPA opted to use VOC emission offsets to mitigate any possibility of adverse air quality impact that may result from the small increase in VOC emissions. These relied-upon emission offsets are from permanently shut down emission units at one facility in Ashtabula (4.88 tpy offset VOCs) and one facility in Hamilton (18.65 tpy offset VOCs) counties located in the Cincinnati and Cleveland nonattainment areas, respectively. The 4.88 tpy offset VOCs in Ashtabula County are from the permanently shut down emission unit R010 at the RMC USA Inc. facility (Facility ID 0204000423), the emission unit was permanently shut down on 7/16/2014. The 18.65 tpy offset VOCs in Hamilton County are from the permanently shut down emission unit P001 at the Rock-Tenn Converting Co. facility (Facility ID 1431070952), the emission unit was permanently shut down on 11/21/

    2014. This 18.65 tpy offset VOCs is to offset the possible VOC increases in Hamilton and Butler Counties, combined. The VOC emission reductions have been verified and validated through OEPA's Stars II system and are considered creditable since they are surplus, quantifiable, permanent and federally enforceable. OEPA maintains a database of all emission reductions used for purpose of CAA 110(l) demonstrations and these VOC reductions will be tracked within this database to ensure they cannot be used again. OEPA has committed to permanently retire the 25.33 tpy of VOC emissions upon EPA's approval of this SIP revision and EPA's proposed approval of this SIP revision is based on that commitment. The VOC emission reductions from the permanent emission unit shut downs will offset the predicted VOC emissions increase in these VOC nonattainment areas resulting from the less than 10 tpy BAT exemption and ensure that plans to bring the VOC nonattainment with the NAAQS are not compromised and thus it is expected there will be no adverse impact on air quality.

    OEPA's 110(l) analysis demonstrated that the air quality will not be negatively impacted due to the small increase in emissions as result of the less than 10 tpy BAT exemption. OEPA's 110(l) analysis demonstrated that the VOC emission offsets from the shutdown emission units at the two facilities will counterbalance the estimated emission increase in VOC emissions due to the less than 10 tpy BAT exemption and will not have a negative impact on air quality nor cause backsliding from Ohio's reasonable further progress plans. OEPA will formally retire the VOC emission offsets in order to receive final approval of this SIP revision. OEPA's 110(l) analysis also demonstrated that the small increase in VOC emissions in Ohio's ozone attainment areas will not have a negative impact on air quality because the increase in VOC emissions is very small compared to the VOC emissions emitted state-

    wide.

  8. What action is EPA taking?

    EPA is proposing approval, into the SIP, of the rule revision to OAC 3745-31-05(A)(3)(a)(ii) that OEPA submitted on May 22, 2018. The SIP revision submitted, described in section I, above, is consistent with Federal regulations governing state permitting programs. See section II above. EPA is also soliciting comment on this proposed approval.

  9. 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 requirements of 1 CFR 51.5, EPA is proposing to incorporate by reference revisions to Ohio Administrative Code 3745-31-

    05(A)(3)(a)(ii), effective on May 1, 2016. EPA has made, and will continue to make, these documents generally available through www.regulations.gov and at the EPA Region 5 Office (please contact the person identified in the For Further Information Contact section of this preamble for more information).

  10. Statutory and Executive Order Reviews

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

    Is not an Executive Order 13771 (82 FR 9339, February 2, 2017) regulatory action because SIP approvals are exempted under Executive Order 12866;

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

    Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);

    Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);

    Does not have Federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);

    Page 56777

    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, the SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
