## Background The purpose of this document is to provide the US Environmental Protection Agency (EPA) with certification that the Idaho State Implementation Plan (SIP) for air quality adequately meets the "infrastructure" requirements of 42 USC §7410 (sections 110(a)(1) and (a)(2) of the Clean Air Act [CAA]). To comply with section 110(a)(1), each state must adopt and submit to EPA a plan that provides for implementation, maintenance, and enforcement of any newly promulgated national primary ambient air quality standard. This plan is due within 3 years of promulgation of the standard or a shorter period if required by the final rule. The state must provide reasonable notice and public hearing prior to submitting the plan to EPA. The revised sulfur dioxide national ambient air quality standard (NAAQS) was promulgated on June 3, 2010. In accordance with section 110(a)(1), Idaho is submitting this plan to meet the infrastructure requirements of sections 110(a)(1) and (a)(2). The following table demonstrates how Idaho meets each of the applicable requirements of section 110(a)(2). Idaho’s air quality laws are located in the Idaho Environmental Protection and Health Act (EPHA), Idaho Code 39-101 through 39-130. The “Rules for the Control of Air Pollution in Idaho” are located at IDAPA 58.01.01. The table that follows presents a listing of the CAA section 110(a)(2) SIP requirements and a very brief explanation of how Idaho’s EPHA and IDAPA rules satisfy those requirements for the 2010 sulfur dioxide NAAQS.Certification of SIP Adequacy for the 2010 SO 2 NAAQS

## Explanation of SIP Adequacy
Clean Air Act section (SIP requirements) How Idaho addressed the §110(a)(2) requirements §110(a)(2)(A)
Include enforceable emission limitations and other control measures, means, or techniques (including economic incentives such as fees, marketable permits, and auctions of emissions rights), as well as schedules and timetables for compliance, as may be necessary or appropriate to meet the applicable requirements of this act;  Idaho Code 39-105(3)(d) provides the Idaho Department of Environmental Quality (DEQ) broad power to supervise and administer a system to safeguard air quality.

 Idaho Code 39-115 provides authority for issuance of air quality permits.

 Idaho Code 39-116 provides authority to establish compliance schedules. Rules relating to air quality permits and fees:

 IDAPA 58.01.01.200–228 addresses permits to construct.

 IDAPA 58.01.01.300–399 addresses Tier I operating permits.

 IDAPA 58.01.01.400–410 addresses operating permits pre-dating Title V (i.e., Tier II operating permits). Rules for open burning, fugitive emissions, visible emissions, and sulfur content of fuel requirements:

 IDAPA 58.01.01.600–624 includes the rules for the control of open burning. IDAPA 58.01.01.625 includes specific visible emission requirements and testing.

 IDAPA 58.01.01.725 applies to fuel burning sources with the purpose of preventing excessive ground level concentrations of sulfur dioxide. Rules addressing other economic incentives:

 IDAPA 58.01.01.460–461 addresses banking of emissions. Together these statutes and rules provide DEQ the authority to regulate the discharge of air pollutants and to promulgate rules to establish standards for emissions for ambient air quality.Certification of SIP Adequacy for the 2010 SO 2 NAAQS

3 §110(a)(2)(B) Provide for establishment and operation of appropriate devices, methods, systems, and procedures necessary to— (i) monitor, compile, and analyze data on ambient air quality, and (ii) upon request, make such data available to the Administrator;  IDAPA 58.01.01.107 incorporates 40 CFR Parts 50, 53, and 58 Appendix B.

 IDAPA 58.01.01.576.05 incorporates 40 CFR Parts 50 and 53 for defining ambient air monitoring methods. The above rules give Idaho authority to implement ambient air monitoring surveillance systems in accordance with the requirements of referenced sections of the CAA. The collected information is analyzed and submitted to EPA. EPA approved the 2012 Idaho Annual Ambient Air Monitoring Network Plan in a letter from Debra Suzuki on October 25, 2012 (Appendix A). DEQ’s annual air network monitoring plan, air quality monitoring summaries, a map of the state’s air monitoring network, and a link to real-time air monitoring are available at http://www.deq.idaho.gov/airquality/monitoring/monitoring-network.aspx

4 §110(a)(2)(C) Include a program to provide for the enforcement of the measures described in subparagraph (A), and regulation of the modification and construction of any stationary source within the areas covered by the plan as necessary to assure the national ambient air quality standards are achieved, including a permit program as required in parts C and D;  Idaho Code 39-108 (Administrative and Civil Enforcement) provides DEQ with the authority to enforce both administratively and civilly the EPHA or any rule, permit, or order pursuant to EPHA.

 Idaho Code 39-109 contains criminal enforcement authority.

 Idaho Code 39-112 provides for emergency orders.

 IDAPA 58.01.01.200–228 contains the procedures and requirements for permits to construct. Also see §110(a)(2)(A) discussion and sections relating to air quality permits (page 2). Initial prevention of significant deterioration (PSD) delegation was provided in a memorandum of understanding from Gary L. O’Neal, Region 10 air and toxics division director, on November 28, 1986. DEQ’s PSD program is federally approved and covers all regulated pollutants. The regulations for 40 CFR 52.683 are available athttp://www.ecfr.gov/cgibin/retrieveECFR?gp=1&SID=657f35928d6029edee7ac574997a8ffd&ty=HTML&h=L&r= PART&n=40y3.0.1.1.1

. DEQ updates ambient air quality standards and changes to the PSD program (such as increments, significant impact levels, significant monitoring concentrations, definitions of major, etc.) as part of the annual incorporation-by-reference (IBR) rulemaking. These IBR updates, along with IDAPA 58.01.01.200–228, cover both minor and major permitting requirements for new and modified sources, and IDAPA 58.01.01.575–587 (Air Quality Standards and Area Classification) provide DEQ with the authority to implement the PSD and new source review (NSR) programs.Certification of SIP Adequacy for the 2010 SO 2 NAAQS

5 §110(a)(2)(D) Contain adequate provisions— (i) prohibiting, consistent with the provisions of this title, any source or other type of emissions activity within the State from emitting any air pollutant in amounts which will— (I) contribute significantly to nonattainment in, or interfere with maintenance by, any other State with respect to any such national primary or secondary ambient air quality standard, or (II) interfere with measures required to be included in the applicable implementation plan for any other State under part C to prevent significant deterioration of air quality or to protect visibility, (ii) insuring compliance with the applicable requirements of sections 126 and 115 (relating to interstate and international pollution abatement); (D)(i)(I): On February 6, 2013, Dennis J. McLerran EPA regional administrator, sent Idaho Governor Otter a letter stating, “On July 27, 2012, the EPA announced that it had insufficient information to complete the designations for the 1-hour SO2 standard within two years and extended the designations deadline to June 3, 2013.” Therefore at this time, Idaho has not been shown to significantly contribute to nonattainment or interfere with maintenance of the 2010 SO2 NAAQS in another state. Until the EME Homer City Generation, L.P., v. EPA, 696 F .3d 7, decision is reversed or otherwise modified by the Supreme Court, states are not required to submit section 110(a)(2)(D)(i)(I). Pending this decision and EPA’s policy and implementation guidance, Idaho will submit an interstate transport SIP to satisfy the requirements of this section. (D)(i)(II) regarding part C (PSD): DEQ received delegation of the PSD program on November 28, 1986, from Gary L. O’Neal, Region 10 air and toxics division director. DEQ’s PSD program is federally approved and covers all regulated pollutants.
