## Background The purpose of this document is to provide the U.S. Environmental Protection Agency (EPA) with certification that the Idaho State Implementation Plan (SIP) for air quality adequately meets the "infrastructure" requirements of 42 U.S.C. § 7410 (sections 110(a)(1) and (a)(2) of the Clean Air Act [CAA]). In order 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 three 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 lead national ambient air quality standard (NAAQS) was promulgated on November 12, 2008. 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 in the Idaho Administrative Procedures Act (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 2008 lead 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 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—permits to construct  IDAPA 58.01.01.300–.399—Tier I operating permits  IDAPA 58.01.01.400–.410—operating permits pre-dating Title V Rules for open burning, fugitive emissions, and visible emission requirements:  IDAPA 58.01.01.600–.623 includes the rules for the control of open burning.  IDAPA 58.01.01.650–.651 requires the reasonable control of fugitive emissions. IDAPA 58.01.01.625 includes specific visible emission requirements and testing. 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.

§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 into IDAPA.  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 2010 Idaho Ambient Air Monitoring Network Plan in a letter from Debra Suzuki on October 14, 2010 (Appendix A). §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. Also see §110(a)(2)(A) discussion and sections relating to air quality permits. 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 (Appendix B). 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 (Permitting Requirements for New and Modified Sources) and 575–587 (Air Quality Standards and Area Classification) provide DEQ with the authority to implement the PSD and New Source Review (NSR) programs.

§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): East Helena, located in west central Montana, is the only lead nonattainment area in the surrounding states. The primary cause of the nonattainment area was ASARCO’s lead smelter, which was mothballed in 2001. The facility permit has since been revoked. The next closest lead nonattainment area to Idaho is located in Los Angeles, California. According to EPA’s final 2008 lead rule, “lead emissions do not generally transport over long distances (as compared, e.g., to fine particulate).” EPA also stated that “at the revised level of the standard, EPA expects stationary sources to be the primary contributor to violations of the NAAQS, although we also believe the nearby area sources may also contribute to concentrations of lead emissions that may affect a violating monitor. In light of the possibility that a number of smaller sources may collectively contribute to concentrations in excess of the NAAQS, EPA believes that adopting the county boundary as the presumptive boundaries for lead nonattainment areas is appropriate.” The South Coast Air Quality Management District (AQMD) designation as a lead nonattainment area provides a good example of how emissions, geography, and the fast deposition of lead particles play into relatively small nonattainment area boundaries. The emissions from the three largest facilities in Los Angeles County are found within the South Coast AQMD with rough emissions of 1.9 tons per year (EXIDE), 0.32 tons per year (Quemetco Inc.), and 0.04 tons per year (Trojan Battery).1

### Van Nuys Airport, with an emission of 1.4 tons per year of lead, is also in the South Coast AQMD. Modeling shows how fast the concentration rates drop with distance. EXIDE concentrations show a high of 0.5 micrograms per cubic meter (μg/m3

### ) and drop to 0.15 μg/m3 

### within 375–500 meters from the facility. Quemetco drops from 0.03 μg/m3

### to 0.0015 μg/m3

### within 250 meters of the source.2

### 6 In looking at geography’s impact on the boundaries, EPA agreed with the South Coast AQMD that the mountains separating the South Coast and Mojave AQMDs acted as a barrier to air flow, given the weight of lead particles and the rapidly decreasing concentrations with distance from a source. Therefore, only the South Coast AQMD portion of Los Angeles County should be classified as a lead nonattainment area.3 

### The map in Appendix C shows the location of Idaho’s largest point and area sources (airports) and that all emit well below 0.5 tons per year.4 

### The lead sources are very dispersed and far away from the nearest nonattainment area in East Helena. There are also several mountain ranges between Idaho’s lead sources and East Helena and the South Coast AQMD. Idaho’s very small lead emission sources, combined with the distance and terrain between the closest lead nonattainment areas, provide evidence that Idaho is not causing or contributing to any lead maintenance or nonattainment issues or interfering with any control measures in applicable implementation plans in other states. (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 (Appendix B). On December 27, 2010, EPA approved numerous revisions to Idaho’s State Implementation Plan. Many of these revisions related to Idaho’s permitting and PSD program.5

OFFICE OF AIR, WASTE AND TOXICS October 14, 2010 Mr. Brad Broker Air Quality Monitoring Coordinator Idaho Department of Environmental Quality 1410 North Hilton Boise, ID 83706-1255 Dear Mr. Broker: We have evaluated the 2010 Idaho Ambient Air Monitoring Network Plan, which describes the Idaho monitoring network for 2010-11. IDEQproposesthe following changes to the air monitoring network: 1)DEQ proposes to initiate PMcoarse monitoring at the Meridian — St. Luke's NCore site, beginning January 1, 2011, and report this data to AQS. DEQ will calculate PMcoarse concentrations by calculating the mass difference between data collected from the existing PM2.5 FRM at St. Luke's,andthe PMIO FRM proposed for that site. EPA approves this change. 2)DEQ proposes increasing the sampling frequency at the Salmon PM2.5 monitoring site to daily (1:1). The monitor currently operates every third day (1:3). EPA approves this change. The following monitors are designated "core" monitors because they are either: 1) required by 40 CFR Part 58, Appendix D, 2) have a design value near or above the new PM2.5 24-hour standard of 35ug1m3, or 3) they are essential monitoring parameters at NCore sites: I. PM2.5 FRMs (or Approved Regional Method): a)Nampa (primary and co-located) b)Meridian/St. Luke's Hospital c)Pinehurst d)Salmon e)Franklin t)St Maiies 2. PM2.5 spcciation monitors and pre-cursor gas monitorsat the Meridian/St. Luke's HospitalNCore site. "Core" monitors are those monitors in the network that must be operated with available PM2.5 monitoring funds. The "non-core" PM2.5 monitors in the State's network can be operated at IDEQ's discretion with any remaining federal funds or State funds. If you have any questions about our approval of the Idaho monitoring network, please contact Keith Rose at (206) 553-1949.

### AftQuality Buipau

The State of Idaho has developed the rules necessary to administer the Prevention of Significant Deterioration (PSD) program. This document describes the procedures under which PSD activities will be conducted until the State program can assume full technical responsibility. The State's requirements for technical assistance from EPA Region 10 are defined. proced.ure Two categories of permits must be addressed during the transition from an EPA-operated PSD program to a state-operated PSD program: (1) PSD permits already issued by EPA; and (2) permit applications submitted to EPA before Idaho's program was approved. (1) Permits already issued by EPA (Attachment 1): EPA will retain primary enforcement authority over EPA-issued PSD permits until State operating permits, containing limits at least as stringent as those in the PSD permits, become part of the Idaho SIP. As State operating permits for these facilities expire, IDHW will revise them to be as stringent as the corresponding EPA-issued PSD permits. When these permits are incorporated in the SIP, EPA will delegate primary enforcement authority to Idaho for PSD limits at each facility. Subsequent permit revisions involving revisions to PSD permit limits can be accomplished by Idaho provided they comply with all PSD requirements, including public participation. (2) Permit applications submitted to EPA/IDHW: Three PSD permit activities are currently in various stages of the permitting process: Idaho National Engineering Laboratory (INEL). . . Prior to IDHW receiving PSD program approval (August 22, 1986), EPA/IDHW conducted a parallel technical review on a PSD application submitted by INEL (April 22, 1986). In late May, 1986, both EPA and IDHW determined the INEL application was incomplete. EPA agrees to process existing and future INEL submittals on this specific (Fuel Processing Restoration Project) application to determine completeness. Once

EPA will draft the technical analysis document and will, with cooperation from the IDHW, write a draft PSD permit. IDHW will be responsible for the public comment period on the draft permit and issuing the - final PSD permit. J.R. Simplot Company (Conda). . . Prior to IDHW receiving PSD program approval, EPA/IDHW conducted a parallel technical review on a PSD application submitted by the J.R. Simplot Company in Conde (July 15, 1986). On August 20, 1986, based on EPA's technical review, IDHW notified the J.R. Simplot Company that their application was incomplete. IDHW agrees, with technical assistance from EPA, to take the lead in processing existing and future J.R. Simplot submittals on this specific (Fuel Coal Firing of #2 Conda Phosphate Rock Dryer) application. The state is responsible for developing the technical analysis document and issuing the final PSD permit. J.R. Simplot Company (Pocatello). . . On April 30, 1986, prior to 'DEW receiving PSD program approval EPA registered numerous concerns relative to previously issued IDHW permits dealing with the company's plant expansion. EPA/IDHW agreed that EPA would be responsible for taking the lead role in revising the permits to insure federal enforceability. EPA agrees to continue its lead role in processing these permits. The J.R. Simplot Company is proposing to submit a PSD permit application to accommodate proposed increases in emissions. EPA and IDHW will cooperatively draft the technical analysis document and write a draft PSD permit. IDHW will be responsible for the public comment period on the draft permit and issuing the final PSD permit. Conditions (1) EPA will provide technical and administrative assistance. EPA will provide technical support (including necessary travel) and oversight to the State for the first four PSD permit applications or the first two years of delegation. After two years or the issuance of the first four permits, EPA technical assistance will be available upon request to the extentresources are available. Oversight will beaccomplished through periodic program reviews.
