Secretary’s Order No.: 2013-A-0019
Approving Final Revision to Delaware’s State Implementation Plan (SIP) for the Implementation, Maintenance and Enforcement of the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS), Pursuant to the Requirements of Section 110(a)(2)(A)-(M) of the Federal Clean Air Act (CAA)
Date of Issuance: May 29, 2013
This Order considers the proposed revision to the Delaware State Implementation Plan (SIP) that addresses the requirements of Section 110(a)(2)(A)-(M) of the federal Clean Air Act (CAA) for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS). Effective June 2, 2010, the U.S. Environmental Protection Agency (EPA) strengthened the sulfur dioxide NAAQS by adding a new 1-hour standard of 75 parts per billion. Section 110(a) of the Clean Air Act requires States to submit to EPA a SIP that provides for implementation, maintenance, and enforcement of a newly promulgated or revised NAAQS. Section 110(a)(2) lists the elements that are to comprise the implementation plan, which include basic program elements such as enforceable emission limitations and control measures, air quality monitoring and modeling, a permitting program, adequate funding and personnel, authority under state law to carry out the plan, emissions reporting, emergency powers, public participation, and fee collection.
The proposed SIP document discusses how Delaware meets each requirement of Section 110(a)(2)(A)-(M) of the Clean Air Act for the 2010 sulfur dioxide NAAQS. Because there have been NAAQS in existence for many years that cover sulfur dioxide, the Clean Air Act Section 110 infrastructure requirements are already substantially addressed in Delaware’s SIP. Consequently, this revision contains no new rules or regulations.
The Department published its initial proposed revision to the aforementioned Delaware SIP in the April 1, 2013 Delaware Register of Regulations, and held a public hearing on April 24, 2013. It should be noted that no members of the public attended the aforementioned hearing held by the Department, however, comment was received from EPA on April 22, 2013 with regard to this proposed SIP. The Department thoroughly reviewed EPA’s comments and responded to the same fully by adding some additional citations and references within the Plan for improved clarity and understanding.
The Department’s presiding hearing officer, Lisa A. Vest, prepared a Hearing Officer’s Report dated May 28, 2013 (Report). The Report recommends certain findings and the adoption of the proposed revision to Delaware’s State Implementation Plan, which addresses the requirements of Section 110(a)(2)(A)-(M) of the federal Clean Air Act (CAA) for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS), as attached to the Report as Appendix A.
I find that the Department’s experts in the Division of Air Quality fully developed the record to support adoption of the proposed revision to the Delaware State Implementation Plan (SIP) that addresses the requirements of Section 110(a)(2)(A)-(M) of the federal Clean Air Act (CAA) for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS). With the adoption of this Order, Delaware will once again demonstrate that the contingency requirements of the Clean Air Act (CAA) are met.
2.)	The Department provided adequate public notice of the proposed SIP revision, and provided the public with an adequate opportunity to comment on the proposed SIP revision, including at the public hearing held on April 24, 2013;
3.) The Department held a public hearing on April 24, 2013, in order to consider public comment before making any final decision;
5.) The recommended revision to Delaware’s State Implementation Plan (SIP) which addresses the requirements of Section 110(a)(2)(A)-(M) of the federal Clean Air Act (CAA) for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS) should be adopted as final, thereby enabling Delaware to (1) demonstrate that the contingency requirements of the Clean Air Act (CAA) are met; and (2) because the revision is well supported by documents in the record;
6.) The Department shall submit this Order approving the final revision to Delaware’s State Implementation Plan (SIP) that addresses the requirements of Section 110(a)(2)(A)-(M) of the federal Clean Air Act (CAA) for the 2010 Sulfur Dioxide (SO2) National Ambient Air Quality Standard (NAAQS) to the Delaware Register of Regulations for publication in its next available issue, and provide such other notice as the law and regulation require and the Department determines is appropriate.
State Implementation Plan Revision to address the Clean Air Act Section 110 Infrastructure Elements For the 2010 Nitrogen Dioxide NAAQS
7 DE Admin. Code 1109, Emissions Of Sulfur Compounds From Industrial Operations
7 DE Admin. Code 1136, Acid Rain Program
7 DE Admin. Code 1144, Stationary Generator Emissions, November 1, 2007
7 DE Admin. Code 1145,Excessive Idling Of Heavy Duty Vehicles, August 12, 2005
7 DE Admin. Code 1146 Electric Generating Unit (EGU) Multi-Pollutant Regulation, November 21, 2006
7 DE Admin. Code 1125 fulfills parts C and D of Title I of the CAA; governing preconstruction review and permitting of any new or modified major stationary sources of air pollutants. 1125 is approved in the DE SIP. Under 1125 any major source or modification that results in a net significant increase of SO2 (40 TPY or greater) must apply Best Available Control Technology (BACT) to reduce SO2 emissions.
SO2 is readily removed from the atmosphere through processes such as scavenging, chemical reactions, soil and surface water absorption, and dry deposition. Because of these removal processes the highest ambient concentrations of SO2 emissions generally occur relatively close to one or a few key SO2 sources in an area (often within 10‐20 kilometers of that parent source or sources) and decrease quickly as the distance from an SO2 source increases.6 Thus, from an air quality management perspective, the SO2 NAAQS is considered to be a “source-oriented” NAAQS rather than a “regional” one (i.e., more similar to the lead NAAQS than the ozone NAAQS). Accordingly, in order for SO2 emissions from Delaware to contribute significantly to nonattainment in, or interfere with maintenance by, any other state, the nonattainment or maintenance area would need to be located in close proximity to a source in Delaware.
110(a)(2)(D)(i)(II): The requirements of CAA 110(a)(2)(D)(i)(II) are met by new major sources and major modifications in Delaware being subject to the PSD requirements which are contained in Section 3.0 of 7 DE Admin Code 1125, Preconstruction Review. The visibility prong of §110(a)(2)(D)(i)(II) has been met through an approved regional haze state implementation plan (SIP). Delaware’s regional haze SIP was approved on July 19, 2011 (76 FR 42557).
Delaware’s Plan: For §110(a)(2)(E)(i), Delaware has adequate authority under state law pursuant to 7 Del.C. Chapter 60 to carry out its SIP obligations with respect to the 2010 SO2 NAAQS. DNREC does not believe that there is any prohibition in any federal or state law that would prevent it from carrying out its SIP or any portion thereof. Further, DNREC assures EPA that it has, through the State of Delaware General Fund and through the Title V fee program, and will continue to have, funding to carry out its SIP obligations. Further, DNREC believes its funding sources are sufficient to provide adequate personnel for those purposes; however, Delaware may makes changes that it believes in its discretion are appropriate, while continuing to fulfill this obligation.
For §110(a)(2)(E)(ii), Delaware finalized a SIP document that satisfies CAA §110(a)(2)(E)(ii) and §128 by including in the SIP applicable requirements of 29 Del.C., Ch. 58, “Laws Regulating the Conduct of Officers and Employees of the State.” This final document was submitted to the EPA as a SIP revision on January 11, 2013 and was approved and published in the Federal Register on April 17, 2013 (78 FR 22785).
Delaware’s Plan: Delaware has the authority and technical capability to conduct air quality modeling in order to assess the effect on ambient air quality of relevant pollutant emissions, and will continue to perform modeling as necessary, but may make changes that it believes in its discretion are appropriate, while continuing to fulfill this obligation. Delaware will continue to submit to the EPA the Air Quality modeling data as part of Delaware's relevant SIP submissions, permit actions,11 and through federal grant commitments or in other ways that EPA may request.
Delaware’s Plan: In a manner consistent with Delaware law, Delaware will continue to require the owner or operator of each major stationary source to pay to the permitting authority, as a condition of any permit required under this Act, a fee sufficient to cover (i) the reasonable costs of reviewing and acting upon any application for such a permit, and (ii) if the owner or operator receives a permit for such source, the reasonable costs of implementing and enforcing the terms and conditions of any such permit (not including any court costs or other costs associated with any enforcement action), until such fee requirement is superseded with respect to such sources by the Administrator’s approval of a fee program under title V pursuant to Delaware law. Delaware currently fulfills this under the enabling authority of 7 Del. C. §S 6095 to 6099 and fee legislation that currently is renewed every three years. Delaware has a fully approved Title V operating permits program. See paragraphs (b) and (c) under “Delaware” in Appendix A to 40 CFR Part 70—Approval Status of State and Local Operating Permits Programs. Delaware may make changes that it believes in its discretion are appropriate, while continuing to fulfill this obligation.
