Implementation Plans
This document provides information and analysis sup porting the EPA’s proposed action on Utah’s Area Source Rules and other genera l rule revisions submitted on February 2, 2012, May 9, 2013; June 8, 2013; Februa ry 18, 2014; April 17, 2014; May 20, 2014; July 10, 2014; August 6, 2014; and Decemb er 9, 2014 and proposed action on the reasonably available control measures for the a rea source rules submitted with Utah’s December 16, 2014 2006 24-Hour fine particulate mat ter (PM 2.5 ) Plans. The Salt Lake, Provo, and Logan nonattainment areas in Utah are cu rrently designated nonattainment and classified as moderate for the 2006 PM 2.5 standard. See 79 FR 31566 (June 2, 2014) and 40 CFR § 81.345.
I. Regulatory Background On October 17, 2006 (71 FR 61144), the EPA strengt hened the level of the 24- hour PM 2.5 National Ambient Air Quality Standards (NAAQS), lo wering the primary and secondary standards from 65 micrograms per cubic me ter (μg/m 3 ), the 1997 standard, to 35μg/m 3 . On November 13, 2009 (74 FR 58688), the EPA desig nated three nonattainment areas in Utah for the 24-hour PM 2.5 NAAQS of 35 μg/m 3 . These are the Salt Lake City, UT; Provo, UT; and Logan, UT-ID non attainment areas. The EPA originally designated these areas under Clean Air A ct (CAA or Act) title I, part D,4

subpart 1, which required Utah to submit an attainm ent plan for each area no later than three years from the date of their nonattainment de signations. These plans needed to provide for the attainment of the PM 2.5 standard as expeditiously as practicable, but no later than five years from the date the areas were designated nonattainment. Subsequently, on January 4, 2013, the U.S. Court o f Appeals for the District of Columbia held that the EPA should have implemented the 2006 PM 2.5 24-hour standard based on both CAA title I, part D, subpart 1 and su bpart 4. Under subpart 4, nonattainment areas are initially classified as mod erate, and moderate area attainment plans must address the requirements of subpart 4 as well as subpart 1. Additionally, CAA subpart 4 sets a different State Implementation Pla n (SIP) submittal due date and attainment year. For a moderate area, the attainmen t SIP is due 18 months after designation and the attainment year is the end of t he sixth calendar year after designation. On June 2, 2014 (79 FR 31566), the EPA finalized th e Identification of Nonattainment Classification and Deadlines for Submission of Stat e Implementation Plan (SIP) Provisions for the 1997 Fine Particulate (PM 2.5 ) National Ambient Air Quality Standard (NAAQS) and 2006 PM 2.5 NAAQS (“the Classification and Deadline Rule”). Th is rule classified to moderate the areas that were designat ed in 2009 as nonattainment, and set the attainment SIP submittal due date for those are as at December 31, 2014. This rule did not affect the moderate area attainment date of Dec ember 31, 2015. On March 23, 2015, the EPA proposed the Fine Parti culate Matter National Ambient Air Quality Standards: State Implementation Plan Requirements (“PM 2.5 Implementation Rule”), 80 FR 15340, which partially addresses the January 4, 2013 court ruling. This proposed rule details how air agencies should meet the statutory SIP5

requirements that apply under subparts 1 and 4 to a reas designated nonattainment for any
PM 2.5 NAAQS, such as: general requirements for attainmen t plan due dates and attainment demonstrations; provisions for demonstra ting reasonable further progress; quantitative milestones; contingency measures; Nona ttainment New Source Review (NNSR) permitting programs; and reasonably availabl e control measures (RACM) (including reasonably available control technology (RACT)), among other things. The statutory attainment planning requirements of subpa rts 1 and 4 were established to ensure that the following goals of the CAA are met: (i) Th at states implement measures that provide for attainment of the PM 2.5 NAAQS as expeditiously as practicable; and, (ii) t hat states adopt emissions reduction strategies that wi ll be the most effective, and the most cost-effective, at reducing PM 2.5 levels in nonattainment areas. The PM 2.5 Implementation Rule proposed a process for states to determine the control strategy for PM 2.5 attainment plans. The process consists of identify ing all technologically and economically feasible control m easures, including control technologies for all sources of direct PM 2.5 and PM 2.5 precursors in the emissions inventory for the nonattainment area which are not otherwise exempted from consideration for controls. 1 From that list of measures, the state must identif y those that it can implement within four years of designation of t he area (and which would thus meet the statutory requirements for RACM and RACT) and a ny “additional reasonable measures,” which EPA is proposing in the PM 2.5 Implementation Rule to define as those technologically and economically feasible measures that the state can only implement on

1 Such exemptions could be due to a demonstrated lac k of significant contribution of a certain PM 2.5 precursor to the area’s elevated PM 2.5 concentrations or due to a presumptive determinati on that a certain source category contributes only a de minimis amount toward PM 2.5 levels in a nonattainment area.6

sources in the nonattainment area after the four ye ar deadline for RACM and RACT has passed. See proposed 40 CFR 51.1000.
II. RACT and RACM Requirements for PM 2.5 Attainment Plans Section 172(c)(1) of the Act (from subpart 1) requi res that attainment plans, in general, provide for the implementation of all RACM as expeditiously as practicable (including RACT) and shall provide for attainment o f the national primary ambient air quality standards. Section 189(a)(1)(C) (from subpa rt 4) requires moderate area attainment plans to contain provisions to assure th at RACM is implemented no later than 4 years after designation. As part of the RACM/RACT analysis, all available co ntrols should be evaluated, and reasonable controls should be adopted. The EPA stated its interpretation of the RACT and R ACM requirements of subparts 1 and 4 in the 1992 General Preamble for t he Implementation of Title I of the Clean Air Act Amendments of 1990, 57 FR 13498 (Apr. 6, 1992). For RACT, the EPA followed its “historic definition of RACT as the lo west emission limitation that a particular source is capable of meeting by the appl ication of control technology that is reasonably available considering technological and economic feasibility." 57 FR 13541. Like RACT, the EPA has historically considered RACM to consist of control measures that are reasonably available, considering technolo gical and economic feasibility. See
PM 2.5 Implementation Rule, 80 FR 15373. The EPA recommends that states use the following pr ocess to identify RACM/RACT:
1. Develop a comprehensive list of available control m easures for all source categories in the nonattainment area. In developing this list, the state should identify existing7 control measures currently being implemented in the area and also include any control measures suggested in public comments.
2. Remove from the list any measure that is unreasonab le because emissions from the affected source or source category are insignifican t (i.e., de minimis). The state should appropriately document any determination tha t a source or source category is insignificant. 3. Evaluate each remaining available control measure f or its “reasonableness,” considering technological and economic feasibility and any potentially adverse impacts. The state should provide a reasoned justif ication if it rejects a listed control measure as unreasonable.
4. Include in its submitted Moderate area attainment p lan, in enforceable form, each control measure found to be reasonable unless the m easure is already either federally promulgated, part of the state’s SIP, or otherwise creditable in SIPs. In areas that demonstrate attainment by the Moderate area attainm ent date, the state may justify rejection of an otherwise reasonable measure by dem onstrating that the measure would not, individually or collectively with other reasonable measures being rejected, advance attainment by one year or more. For areas t hat demonstrate that attainment by the Moderate area attainment date is impracticab le, the state must provide for the implementation of all available control measures th at are technologically and economically feasible.
See General Preamble at 13540-13544. An evaluation of technological feasibility should i nclude consideration of factors such as a source’s process and operating conditions , raw materials, physical plant layout, and8

non-air quality and energy impacts (e.g., increased water pollution, waste disposal, and energy requirements) (57 FR 18070, 18073). An evaluation of economic feasibility should includ e consideration of factors such as cost per ton of pollution reduced (cost-effectivene ss), capital costs, and annualized cost (57 FR 18070, 18074). Absent other indications, the EPA presumes that it is reasonable for similar sources to bear similar costs of emissions reductions. Economic feasibility of RACM and RACT is thus largely informed by evidence that other sources in a source category have in fact applied the control technology, process cha nge, or measure in question in similar circumstances.

. III. Utah’s PM 2.5 Attainment Plan Submittals Prior to the January 4, 2013 decision of the D.C. C ircuit Court of Appeals, Utah developed a PM 2.5 attainment plan intended to meet the requirements of subpart 1. The EPA submitted written comments dated November 1, 20 12 to the Utah Division of Air Quality (DAQ) on Utah's draft PM 2.5 SIP, technical support document (TSD), and area source and other rules. After the court’s decision, Utah amended its attainment plan to address requirements of subpart 4. On December 2, 2 013, the EPA provided comments on Utah's revised draft PM 2.5 SIPs for the Salt Lake City and Provo areas, inclu ding the TSDs and rules in Section IX, Part H. These written comments from EPA included some comments applicable to the rules we are proposing t o act on today. The comment letters can be found within the docket for this action on r egulations.gov. On May 9, 2013; June 8, 2013; February 18, 2014; Ap ril 17, 2014; May 20, 2014; July 10, 2014; August 6, 2014; and December 9, 2014 the State of Utah submitted to EPA various revisions to the DAR, Title R307 - Envi ronmental Quality, set of rules, most of which are applicable to the Utah SIP for PM 2.5 nonattainment areas. The new rules or9

revised rules we are addressing in this proposed ru le were provided by Utah in the nine different submissions listed above, and these rules are: R307-101-2, General Requirements: Definitions; R307-103, Administrative Procedures; R307-303, Commercial Cooking; R307-307, Road Salting and Sand ing; R307-312, Aggregate Processing Operations for PM 2.5 Nonattainment Areas; R307-328, Gasoline Transfer a nd Storage; R307-335, Degreasing and Solvent Cleaning Operations; R307-342, Adhesives and Sealants; R307-343 Emissions Standards for Wood Furniture Manufacturing Operations; R307-344, Paper, Film, and Foil Coating s; R307-345, Fabric and Vinyl Coatings; R307-346, Metal Furniture Surface Coating s; R307-347, Large Appliance Surface Coatings; R307-348, Magnet Wire Coatings; R 307-349, Flat Wood Panel Coatings; R307-350, Miscellaneous Metal Parts and P roducts Coatings; R307-351, Graphic Arts; R307-352, Metal Container, Closure, a nd Coil Coatings; R-307-353, Plastic Parts Coatings; R307-354, Automotive Refini shing Coatings; R307-355, Control of Emissions from Aerospace Manufacture and Rework Facilities; R307-356, Appliance Pilot Light; R307-357, Consumer Products; and R307- 361, Architectural Coatings. A previous rule, Rule R307-340 Surface Coating Proc esses, was replaced in these submittals by the specific rules for coatings liste d above. Utah correspondingly repealed R307-340. In addition, Rule R307-342, Adhesives and Sealants, replaces an unrelated rule, R307-342 Qualifications of Contractors and Te st Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks. The removal of the previous version of R307-342 is addressed by the State’s February 2, 2012 submit tal, which repeals R307-342 and amends R307-328, Gasoline Transfer and Storage, to account for the repeal of R307-342. The final Utah submittal for fourteen of these rule s was the December 9, 201410

submittal. The final Utah submittals for the remain ing rules were from the February 2, 2012; May 9, 2013; June 8, 2013; February 18, 2014; May 20, 2014; and August 6, 2014 submittals.
IV. Utah’s RACM Analyses Generally speaking, DAQ’s RACM analyses are of two types. For source categories that emit volatile organic compounds (VO Cs) because they manufacture or use materials with VOC content (such as solvents), DAQ considered the technologically feasible controls to be manufacture or use of low-V OC materials, or the use of add-on controls with a specified overall control efficienc y. To determine economic feasibility for the RACM levels for the low-VOC materials and for t he control efficiency, DAQ examined EPA’s control technique guidelines (CTGs) and rules for similar source categories from the South Coast Air Quality Managem ent District (SCAQMD), Bay Area Air Quality Management District (BAAQMD), and San J oaquin Valley Air Pollution Control District (SJVAPCD). For rules from one of t hose districts that are cited in this TSD, the rule may be found at the following links:

• BAAQMD: http://www.baaqmd.gov/rules-and-compliance/current- rules

• SCAQMD: http://www.aqmd.gov/home/regulations/rules/scaqmd-r ule-book

• SJAVPCD: https://www.valleyair.org/rules/1ruleslist.htm Finally, DAQ estimated the cost-effectiveness of th e rule in 2011 dollars per ton of VOC removed. Typically, a cost-effectiveness bel ow $5000/ton may be considered reasonable. For source categories other than catego ries that use materials with VOC content (such as source categories that emit nitrog en oxides (NOx), sulfur dioxide (SO 2 ), and/or direct PM 2.5 ), DAQ performed a more category-specific analysis of11

technologically feasible controls and of the econom ic feasibility of those controls. As described below, we propose to determine that Utah reasonably determined RACM for the rules we are approving.
V. EPA’s Review of Individual Area Source Rules
A. R307-101, General Requirement Rule R307-101 provides general requirements that pe rtain to all DAQ R307 rules, which constitute the basis for control of air pollu tion sources in the State of Utah. The primary section is R307-101-2 Definitions, which pr ovide definitions that are applicable to all R307 rules, except for those definitions as specified in individual rules. As part of the development of the SIP for PM 2.5 , three new definitions were originally proposed fo r section R307-101-2, General Requirements, Definitio ns. These new definitions were: “condensable PM 2.5 ,” “filterable PM 2.5 ,” and “PM 2.5 precursor.” Also, under the definition of “significant,” a level of 10 tons per year (tpy) of PM 2.5 was added in reference to a net emissions increase or the potent ial of a source to emit. Then, in reference to public comments received on that origi nal proposal, definitions for “primary
PM 2.5 ” and “secondary PM 2.5 ” were added. The definition of PM 2.5 precursor did not include ammonia, which is factually a precursor to PM 2.5 and should be included in the emissions inventory. DAQ has committed in their let ter dated August 4, 2015 to remove the definition of “PM 2.5 precursor,” as that definition is not used for reg ulatory purposes in Utah’s SIP. Under section 110(k)(4) of the Act, EPA may approve a SIP revision based on a commitment by the State to adopt specifi c enforceable measures by a date certain, but not later than 1 year after the date o f approval of the plan revision. DAQ submitted these revisions of R307-101-2 to the EPA on May 9, 2013. The12

Board proposed for public comment R307-101-2 on Sep tember 5, 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. DAQ made chan ges to section R307-101-2 based on comments that were received, then held a second comment period from January 1 to January 31, 2013 for those revisions. No additional comments were received on section R307-101-2. Lastly, a “Nonsubstantive Rule Amendmen t” was made by Utah to correct a citation to the United States Code of Federal Regul ations 40 CFR 51.100. In accordance with Utah Code Title 19, Chapter 2, Air Conservatio n Act, Utah Code Title 63G, Chapter 3, Administrative Rulemaking Act, and Utah Administ rative Code, R15, Administrative Rules, this change was made without public comment, as appropriate for a nonsubstantive change. This submittal was made by DAQ on May 20, 2014 to the EPA. The final revision of Rule R307-101 was effective J uly 9, 2013, and is applicable to the entire State of Utah. Utah’s rule analysis c an be found within the docket on regulations.gov. EPA is proposing conditional appro val of revisions done to R307-101. If we finalize our proposed conditional approval, Utah must adopt and submit the specific revisions it has committed to within one year of ou r finalization. If Utah does not submit these revisions within one year, or if we find Utah ’s revisions to be incomplete, or we disapprove Utah’s revisions, this conditional appro val will convert to a disapproval. If any of these occur and our conditional approvals co nverts to a disapproval, that will constitute a disapproval of a required plan element under part D of title I of the Act, which starts an 18-month clock for sanctions, see s ection 179(a)(2), and the 2-year clock for a federal implementation plan (FIP), see sectio n 110(c)(1)(B).
B. R307-103, Administrative Procedures13 Rule R307-103 provides administrative procedures th at pertains to all R307 rules, which constitute the basis for control of air pollu tion sources in the State of Utah. R307- 103 has only one section, R307-103-1 - Administrati ve Procedures. The section previously stated: “Administrative proceedings unde r Utah Air Quality Act are governed by Rule R305-6.” The State’s May 20, 2014 submissi on documented a non-substantial change that had become effective January 1, 2014. T he revision corrected the Rule R305 citation within the rule which now states: “Adminis trative proceedings under Utah Air Quality Act are governed by Rule R305-7.” There wa s no changes to rule R305 itself. R305 governs all adjudicative procedures conducted under the authority of the Environmental Quality Code, Utah Code Ann. Title 19 . This rule does not govern the proceedings that result in an initial determination by the Director, including the issuance of the initial determination itself. In accordance with Utah Code Title 19, Chapter 2, Air Conservation Act, Utah Code Title 63G, Chapter 3, A dministrative Rulemaking Act, and Utah Administrative Code, R15, Administrative Rules , this change was made without public comment, as appropriate for a non-substantiv e change. Utah’s rule analysis can be found within the docket on regulations.gov. EPA is proposing approval of the nonsubstantive revisions in R307-103-1. We note that t he CAA does not specify detailed requirements for administrative procedures, with th e exception of section 128 of the Act, regarding conflicts of interest. We are not proposi ng to determine that this nonsubstantive revision addresses the requirements of section 128.
C. R307-303, Commercial Cooking Rule R307-303 is a new rule that establishes emissi on control device requirements to reduce VOC and PM 2.5 emissions from certain commercial cooking14

equipment. Per the rule requirements, owners or ope rators of all chain-driven charbroilers in food service establishments must install, mainta in and operate a catalytic oxidizer for treatment of air emissions from the charbroilers. T he rule applies to all such establishments in the 2006 24-hour PM 2.5 nonattainment areas, which include Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber cou nties. There are specific maintenance, performance and recordkeeping requirem ents to ensure proper operation, and the opacity of the exhaust stream is not to exc eed 20% opacity as determined by using EPA Method 9. EPA proposes to approve the rul e as an enforceable control measure with adequate monitoring, recordkeeping, an d reporting, including adequate test methods. DAQ’s RACM analysis for this rule was based on revi ew of the BAAQMD and the SJVAPCD RACT analyses and the City of Aspen rul e. DAQ made direct contact with the staff at these three air districts, which was m ade to gain actual implementation and front-line performance information and cost. DAQ co nsidered as feasible technologies a catalytic oxidizer, a water scrubber, and an electr onic precipitator. DAQ eliminated the latter two as economically infeasible due to cost-e ffectiveness of $15,000/ton of pollutant removal. As a result, DAQ determined that RACM cons isted of a catalytic oxidizer, with an estimated annual cost of $2,028. EPA proposes to approve DAQ’s RACM determination. On June 8, 2013 DAQ submitted R307-303 as a new rul e to EPA for approval. The Board proposed R307-303 for public comment on J uly 11, 2012, and had a public comment period from August 1 to August 31, 2012. Ad ditionally, a public hearing was held on August 15, 2012. No comments were received, and no one appeared at the15

hearing. Rule R307-303 was effective April 10, 2013, and req uired compliance with the rule beginning September 1, 2013. Utah’s RACM and r ule analysis can be found within the docket regulations.gov. EPA is proposing approv al of the new rule R307-303 and also that R307-303 currently constitutes RACM for the No nattainment Areas for Commercial Cooking for the Utah PM 2.5 SIP.
D. R307-307, Road Salting and Sanding R307-307 is an existing rule that was part of the c oarse particulate matter (PM 10 ) SIP approved by EPA on December 6, 1999 (64 FR 6803 1). This rule establishes requirements for the composition of salt, or abrasi ves such as crushed slag and sand, applied to roads in PM 10 and PM 2.5 nonattainment and maintenance areas as defined in 40 CFR 81.345 (July 1, 2011). The rule also establishe s recordkeeping requirements associated with such applications. The applicable a reas is geographically described within the rule as all regions of Davis, Salt Lake, and Utah counties; all portions of the Cache Valley; all regions in Weber County west of t he Wasatch mountain range; in Box Elder County, from the Wasatch mountain range west to the Promontory mountain range and south of Portage; and in Tooele County, from th e northernmost part of the Oquirrh mountain range to the northern most part of the Sta nsbury mountain range and north of Route 199. The rule was amended by expanding the applicability to include PM 2.5 nonattainment areas; adding magnesium chloride (MgC l 2 ), calcium chloride (CaCl 2 ), and potassium chloride (KCl) to the Records, Content, a nd Alternatives sections of the rule; and adding specific road sections that are exempt f rom certain parts of R307-307.16

Additional revisions to the rule include non-substa ntive changes. The RACT analysis approved as part of the PM 10 SIP approval in 1999 demonstrated a reduction in t he PM 10 emissions from road dust and road salting and sandi ng by 20%. DAQ discusses in their TSD that the reduction in PM 2.5 emissions are an unknown quantity and considered t o be minimal, thus no SIP credit will be taken for this rule. Nonetheless this rule will contribute to PM 2.5 reductions in the non-attainment area by increasin g the geographic applicability and adds value to the SIP. DAQ submitted revisions to R307-307 to the EPA on M ay 9, 2013. The Board proposed these revisions to R307-307 on September 5 , 2012, and the public comment period was held from October 1 to October 31, 2012. Public hearings were held on October 15, 16, and 17, 2012, and public comments w ere received from Utah Department of Transportation (UDOT) and the EPA for the propos ed R307-307 rule revisions. The November 21, 2012 Memo in the docket on regulations .gov summarizes the comments and provides DAQ’s response to these comments. R307 -307 became effective on February 1, 2013 after updating the rule to address the public comments. Finally, a “Non-substantive Rule Amendment” was sub mitted to EPA by Utah on May 20, 2013 to correct a mistakenly omitted word. In several occurrences where the applicable salts applied to roads in Salt Lake, Dav is, or Utah counties were detailed, the sentence read “NaCl, MgCl 2 , CaCl 2 , or KCl.” The sentence was corrected to read “NaCl , MgCl 2 , CaCl 2 , and/or KCl.” In accordance with Utah Code Title 19, Chapter 2, Air Conservation Act, Utah Code Title 63G, Chapter 3, A dministrative Rulemaking Act, and Utah Administrative Code, R15, Administrative Rules , this change was made without public comment, as appropriate for a non-substantiv e change. These revisions became17

effective on February 15, 2013. Required compliance with the rule was already Octob er 1, 1993 for Salt Lake, Davis and Utah counties, and the compliance date fo r the remaining affected counties began January 1, 2014. Utah’s rule analysis can be found within the docket on regulations.gov. Additionally, EPA requested clarif ication pertaining to R307- 307(5)(1)(a) which states “demonstrate to the direc tor that the material applied has no
more PM 10 or PM 2.5 emissions than salt which is at least 92% NaCl, Mg Cl 2 , CaCl 2 , and/or KCl.” The clarification requested is for wh at the Director of DAQ receives from a source that demonstrates the road salt meets the ru les 92%. DAQ provided a letter on August 4, 2015 clarifying that the sources provide a compositional analysis of the road salt to show that it meets the 92% standard found i n R307-307(5)(1)(a). EPA is satisfied with this clarification and is proposing to approve the revisions to R307-307 but not that R307-307 currently constitutes RACM because DAQ did not take SIP credit for this rule.
E. R307-312, Aggregate Processing Operations for PM 2.5 Nonattainment Areas R307-312 is a new rule that establishes emission st andards for sources in the aggregate processing industry, including aggregate processing equipment, hot mix asphalt plants, and concrete batch plants. The rule applies to all crushers, screens, conveyors, hot mix asphalt plants, and concrete bat ch plants located within a PM 2.5 nonattainment and maintenance area as defined in 40 CFR 81.345 (July 1, 2011). This area includes all regions of Salt Lake and Davis co unties; all portions of the Cache Valley; all regions in Weber and Utah counties west of the Wasatch mountain range; in Box Elder County, from the Wasatch mountain range w est to the Promontory mountain range and south of Portage; and in Tooele County, f rom the northernmost part of the18

Oquirrh mountain range to the northern most part of the Stansbury mountain range and north of Route 199. The provisions of R307-312 do n ot apply to temporary hot mix asphalt plants. The rule addresses two aspects of the industry to l imit emissions. One is to limit emissions of direct PM 2.5 from the aggregate processing industry. This is es sentially the material handling aspects of aggregate processing o perations, including crushers, screens, and conveyance systems. Second is addressing the em issions of PM 2.5 precursors from hot mix asphalt plants. This includes emissions fro m combustion sources, mobile sources, generators, engines, heaters, and dryers. For aggre gate processing operations, visible emissions from subject sources may not exceed speci fic opacity limits of 12% for crushers, and 7% for screens, conveyor transfer poi nts and concrete batch plants. The limit on filterable PM 2.5 emissions from a hot mix asphalt plant dryer is 0. 024 gr/dscf. Combustion product emissions from a hot asphalt pla nt are controlled by the fuel burned. Natural gas (NG) or liquefied petroleum gas (LPG) m ust be used to avoid production limitations. If fuel other than NG or LPG is used f rom November 1 to March 1, a hot mix asphalt plant may not produce at more than 50% of i ts rated capacity during that period. Many sources are already meeting several of the req uired limits. Modifications to existing equipment have recently been made or will be made in the near future. All hot mix asphalt plants will be required to comply with the 0.024 gr/dscf limit by December 14, 2015. All remaining sources have already had to comply with R307-312 by June 7,
2013. For the opacity limit, compliance is based on opaci ty observations of emissions conducted according to 40 CFR 60, Appendix A, EPA M ethod 9. Filterable PM 2.519

emissions compliance is determined by 40 CFR 51, Ap pendix M, Method 201A. For the fuel usage requirements, compliance is based on eit her the daily amount of hot mix asphalt produced averaged over the operating day or the daily amount of hot mix asphalt produced while burning a fuel other than natural ga s or LPG averaged over the time the plant is operating while burning a fuel other than natural gas or LPG each day. Compliance is determined by production records and fuel records. DAQ submitted revisions to R307-312 to EPA on May 9 , 2013. The Board proposed R307-312 for public comment on September 5 , 2012, with the public comment period held from October 1 to November 1, 2012. Thr ee public hearings were held on October 15, 16, and 17, 2012. Written comments were received from industry, the public and the EPA. R307-312 was effective February 1, 2013 and require d compliance with the rule began June 7, 2013. Utah’s RACM and rule analysis c an be found in the docket posted on regulations.gov. For direct PM 2.5 , the RACM analysis considered the following as technologically feasible control measures for aggre gate processing: water application, enclosures, and add-on control devices, including a baghouse, electrostatic precipitator, wet scrubber, and cyclone. DAQ considered enclosure s and add-on controls to be not economically feasible for aggregate processing equi pment and determined water application to be RACM at a cost-effectiveness of $ 650/ton. However, water application was not considered feasible for the one existing co ncrete batch plant; DAQ determined RACM to be the existing baghouse and fabric filter controls. The RACM analysis consider the following add-on controls as technolog ically feasible for filterable PM from hot mix asphalt plants: baghouse, electrostatic pr ecipitator, wet scrubber, and cyclone.20

DAQ did not find any controls technologically feasi ble for condensable PM. The analysis considered all the add-on controls to be economical ly feasible; DAQ correspondingly set a direct PM 2.5 limit of 0.024 gr/dscf. For NOx, DAQ considered lo w-NOx burners, NSCR, SCR, and use of natural gas to be technically feasible. DAQ determined that use of natural gas should be RACM. Additionally, EPA requested that DAQ commit to revi se R307-312-5(2)(a) which states “Production shall be determined by scale hou se records or equivalent method on a daily basis.” The requested change is to provide wh at the “equivalent method” that could be used. DAQ committed in their August 4, 2015 lett er to remove “equivalent method” and state “Production shall be determined by scale house records, scale house or belt scale records, or manifest statements on a daily ba sis.” Under section 110(k)(4) of the Act, EPA may approve a SIP revision based on a commitment by the State to adopt specific enforceab le measures by a date certain, but not later than 1 year after the date of approval of the plan revision. If we finalize our proposed conditional approval, Utah must adopt and submit the specific revisions it has committed to within one year of our finalization. I f Utah does not submit these revisions within one year, or if we find Utah’s revisions to be incomplete, or we disapprove Utah’s revisions, this conditional approval will convert t o a disapproval. If any of these occur and our conditional approvals converts to a disappr oval, that will constitute a disapproval of a required plan element under part D of title I of the Act, which starts an 18-month clock for sanctions, see section 179(a)(2), and the 2-year clock for a FIP, see section 110(c)(1)(B). EPA agrees with the revisions that DAQ has committe d to and is proposing a21

conditional approval of the revisions to R307-312 a nd also that R307-312 currently constitutes RACM for the Nonattainment Areas for Ag gregate Processing Operations for the Utah PM 2.5 SIP.
F. R307-328, Gasoline Transfer and Storage On January 5, 2011, the Board proposed for public c omment revisions to R307- 328, Gasoline Transfer and Storage, and held the pu blic comment period from February 1 to March 3, 2012. No public hearings were held due to lack of a request and DAQ received no comments addressing the revisions to R3 07-328. The proposal removes the “Qualified contractor” def inition, eliminates the current December to March testing window, replaces the curr ent testing and vapor tightness standards with the more stringent standard in the f ederal maximum achievable control technology (MACT) for Gasoline Distribution Facilit ies (specifically 40 CFR 6.425(e)), and general administrative changes. Since the MACT standard does not require a certified Tester, the test method and certification requirements in R307-342 were no longer needed thus the reference in R307-328 to R30 7-342 was removed. The compliance schedule for the vapor tightness tes ting standard in R307-328- 7(1) were to apply to tests conducted after June 7, 2011 and all gasoline cargo tanks were to be tested using the vapor tightness testing stan dard in R307-328-7(1) by June 7, 2012. The revisions to R307-328 was adopted by the Board on April 6, 2011 and was effective on June 7, 2011. Utah’s rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested that DAQ commit to revi se R307-328-4(6) which states “A gasoline storage and transfer installatio n that receives inbound loads and22

dispatches outbound loads ("bulk plant") need not c omply with R307-328-4 if it does not have a daily average throughput of more than 3,900 gallons (15,000 or more liters) of gasoline based upon a 30-day rolling average. Such installations shall on-load and offload gasoline by use of bottom or submerged filling or alternate equivalent methods. The emission limitation is based on operating procedure s and equipment specifications using Reasonably Available Control Technology as defined in EPA documents EPA 450/2-77- 026 October 1977, "Control of Hydrocarbons from Tan k Truck Gasoline Loading Terminals," and EPA-450/2-77-035 December 1977, "Co ntrol of Volatile Organic Emissions from Bulk Gasoline Plants." The design ef fectiveness of such equipment and the operating procedures must be documented and sub mitted to and approved by the executive secretary.” The requested change is to re move the “alternative equivalent method” from this section. DAQ committed in their A ugust 4, 2015 letter to remove “alternative equivalent method” and state: “A gasol ine storage and transfer installation that receives inbound loads and dispatches outbound loads ("bulk plant") need not comply with R307-328-4 if it does not have a daily average throughput of more than 3,900 gallons (15,000 or more liters) of gasoline b ased upon a 30-day rolling average. Such installations shall on-load and off-load gasol ine by use of bottom or submerged filling. The emission limitation is based on operat ing procedures and equipment specifications using Reasonably Available Control T echnology as defined in EPA documents EPA 450/2-77-026 October 1977, "Control o f Hydrocarbons from Tank Truck Gasoline Loading Terminals," and EPA-450/2-77-035 D ecember 1977, "Control of Volatile Organic Emissions from Bulk Gasoline Plant s." The design effectiveness of such equipment and the operating procedures must be docu mented and submitted to and23

approved by the executive secretary.” Under section 110(k)(4) of the Act, EPA may approve a SIP revision based on a commitment by the State to adopt specific enforceab le measures by a date certain, but not later than 1 year after the date of approval of the plan revision. If we finalize our proposed conditional approval, Utah must adopt and submit the specific revisions it has committed to within one year of our finalization. I f Utah does not submit these revisions within one year, or if we find Utah’s revisions to be incomplete, or we disapprove Utah’s revisions, this conditional approval will convert t o a disapproval. If any of these occur and our conditional approvals converts to a disappr oval, that will constitute a disapproval of a required plan element under part D of title I of the Act, which starts an 18-month clock for sanctions, see section 179(a)(2), and the 2-year clock for a FIP, see section 110(c)(1)(B). EPA agrees with the revisions that DAQ has committe d to and is proposing to conditionally approve the revisions in R307-328.
G. R307-335, Degreasing and Solvent Cleaning Operation s Rule R307-335 establishes control measures for VOC emissions from parts degreasing in tanks and conveyorized systems and to control emissions during equipment cleaning. The rule applies to all degreasing or sol vent cleaning operations that use VOCs and that are located in PM 10 and PM 2.5 nonattainment and maintenance plan areas as defined in 40 CFR 81.345 (July 1, 2011). The rule is divided into two sections, the first is the tank degreasing portion that has its roots in the 1994 degreasing MACT and the s econd portion is the new section, R307-335-7 Industrial Solvent Cleaning, which is ba sed on EPA CTG for Industrial24

Cleaning Solvents, EPA 453/R-06-001, September 2006 . DAQ estimated a cost effectiveness of $1640/ton of VOC in 2011 dollars f or batch and conveyorized systems, and cost neutral (unless add-on controls are used) for cleaning solvents. We note that the stringency of this rule is generally in line with o ther VOC rules for this source category, for example SCAQMD Rule 1122. Types of processes ad dressed by R307-335 include: cold cleaning facilities; open top vapor degreasers ; conveyorized degreasers; and, general industrial solvent cleaning. The emissions reductio ns are accomplished through prohibition of certain high VOC emitting products a nd specification of equipment design specifics, solvent storage and handling, equipment operation and maintenance, allowed solvents and their properties, emission control sys tem requirements, and recordkeeping and compliance requirements. There are exemptions for the type and use of indust rial cleaning solvents for specific sectors of industry where such requirement s are addressed in other rules. The solvent handling, storage, and disposal, and specif ic solvent properties requirements detailed in R307-335-7 do not apply to aerospace, w ood furniture, shipbuilding and repair, flat wood paneling, large appliance, metal furniture, paper film and foil, plastic parts, miscellaneous metal parts coat and light aut o body and truck assembly coatings, flexible packaging, lithographic and letterpress pr inting materials, fiberglass boat manufacturing materials, and operations that are ex clusively covered by Department 24 of Defense military technical data and performed by a Department of 25 Defense contractor and/or on site at installations owned an d/or 26 operated by the United States Armed Forces. The individual industry specific rule s address requirements, as applicable. On May 9, 2013 DAQ submitted revisions for R307-335 to the EPA. The Board25

proposed these revisions to R307-335 for public com ment on July 11, 2012 and had a public comment period from August 1 to August 31, 2 012 with a public hearing on August 15, 2012. DAQ received many written comments from the aerospace industry, from one industry that treats miscellaneous metals parts, and the EPA. The public hearing attendees were solely from the aerospace industry. On July 22, 2014, DAQ submitted additional revision s to R307-335 to the EPA. This submittal contained multiple revisions to R307 -335, multiple Board hearings, and multiple public comment periods. Initially the Boar d proposed amendments to R307-335 for public comment on July 3, 2013 with a public co mment period from August 1 to September 3, 2013. The amendments to the rule inclu de adding an exemption for operations that are exclusively covered by the Depa rtment of Defense military technical specifications and/or performed by a Department of Defense contractor on site at installations owned or operated by the United State s Armed Forces. Also, language was added to clarify the 15-pound/day rule applicabilit y is from the cleaning process. DAQ received written comments from industry concerning industrial safety concerns and widely available commercial products. Details of th e comments and the State’s rationale in addressing those comments are in DAQ’s July 22, 2014 submittal within the memorandum DAQ-088-13 dated October 23, 2013. Due to additional concerns from industry, on Novemb er 6, 2013, the Board proposed for public comment further amendments to R 307-335. The public comment period was initially held from December 1 to Decemb er 31, 2013. However, during the public comment period, in response to a request, th e comment period was extended to January 10, 2014. The proposed amendments were to: clarify that the requirements of26

R307-335-7(2) apply to operators of industrial solv ent cleaning that emit 15 pounds of VOCs or more per day from the cleaning process; exe mpt military technical data orders in R307-335-7(1); and, propose a general VOC solven t content limit of 2.49lb/gal in R307-335-7(3)(b). Based on comments to these propos ed changes and additions, VOC content limits were again adjusted. Details of the comments and the State’s rationale in addressing those comments are in DAQ’s July 22, 201 4 submittal within the memorandum DAQ-015-14 dated February 11, 2014. On December 9, 2014, DAQ submitted additional revis ions of R307-335 to the EPA. These revisions were due to ongoing EPA concer ns associated with the amount of control removal specified in R307-335, as well as i n other similar area source rules, that control removal be based on the entire control syst em, and that the inspection and recordkeeping requirements for the rules be expande d before they could be approved. On July 2, 2014, the Board proposed for public comment amendments to R307-335 and the public comment period was held from August 1 to Sep tember 2, 2014. The proposed amendments were approved by the Board on October 1, 2014 and the final version of R307-335 was effective on December 1, 2014. The fin al rule contains applicable language to provide for sufficient operating, testi ng, maintenance, reporting and recordkeeping requirements to allow proper complian ce verification and enforcement, as well as appropriate changes associated with our Dec ember 2, 2013 comment letter. In the “Add-On Emission Control Systems Operations” section it reads “An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.” EPA interprets this language to mean that such an alternate test method will be submitted by the Stat e as a SIP revision that is subsequently27

approved by the EPA through the EPA public notice a nd SIP approval process. The May 9, 2013 submittal from DAQ specified that a ll sources within Salt Lake and Davis counties were to be in compliance with R3 07-335-3 through R307-335-6 and R307-335-8 on January 1, 2013. Additionally in the May 9, 2013 submittal, all other sources defined in R307-335-2 were to be in complia nce with all sections of this rule by September 1, 2013. The July 10, 2014 submittal from DAQ specified that all sources within Box Elder, Cache, Utah, Weber, and Tooele counties were to be in compliance with R307-335-7 by August 1, 2014. Utah’s RACM and rule analysis can be found in the d ocket posted on regulations.gov. EPA is proposing approval of all r evisions of R307-335 and that R307- 335 currently constitutes RACM for the Nonattainmen t Areas for Degreasing and Solvent Cleaning Operations for the Utah PM 2.5 SIP.
H. Repeal of R307-340, Surface Coating Processes On September 5, 2012, the Board proposed for public comment the repeal of R307-340 and held the public comment period from Oc tober 1 to October 31, 2012. Public hearings were held on October 15, 16, and 17 , 2012 for this rule repeal and multiple others. DAQ received no comments addressin g the repeal of this rule. DAQ did receive comments for several of the individual coat ings rules that will replace this rule, however those comments will be discussed in each in dividual rule below. Since the coatings industries regulated in R307-340 emit VOCs, DAQ staff wanted to expand the applicability of this rule to include the seven counties found in the
PM 2.5 nonattainment areas. While Utah looked into amendi ng this rule to expand applicability, add new requirements to new coatings industries and attempted to clarify28

regulatory requirements for coating industries, a r epeal of R307-340 and writing new rules for each individual industry was preferable. These individual rules include R307- 343, R307-344, R307-345, R307-346, R307-347, R307-3 48, R307-349, R307-350, R307- 351, and R307-352. The repeal of Rule R307-340 was effective on Februa ry 1, 2013 and submitted to the EPA on May 9, 2013. Utah’s rule analysis can be found in the docket posted on regulations.gov. EPA is proposing that Rule R307-34 0, Surface Coating Processes be repealed from the Utah SIP.
I. Repeal of R307-342, Qualifications of Contractors a nd Test Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks. On January 5, 2011, the Board proposed for public c omment the repeal of R307- 342, Qualifications of Contractors and Test Procedu res for Vapor Recovery Systems for Gasoline Delivery Tanks and held the public comment period from February 1 to March 3, 2012. No public hearings were held due to lack o f a request and DAQ received no comments addressing the repeal of this rule. R307-342, Qualifications of Contractors and Test Pr ocedures for Vapor Recovery Systems for Gasoline Delivery Tanks originally requ ired contractors that performed tests of the vapor recovery systems to follow specified p rocedures and to be qualified annually by the Executive Secretary. DAQ subsequently revise d R307-328, Gasoline Transfer and Storage (see discussion above for this revision), w hich amended the testing requirements for trucks and replacing it with the Federal MACT f or Gasoline Distribution Facilities (specifically 40 CFR 63.425(e)). Since the MACT sta ndard does not require a certified Tester, the test method and certification requireme nts in R307-342 were no longer29

needed. Thus, DAQ repealed the language within R307 -342, Qualifications of Contractors and Test Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks, and replaced it with R307-342, Adhesives and Sealants (see discussion below on this rule). The repeal of R307-342, Qualifications of Contracto rs and Test Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks, was adopted by the Board on April 6, 2011 and was effective on June 7, 2011. This rep eal was submitted to EPA from DAQ on February 2, 2012. Utah’s rule analysis can be fo und in the docket posted on regulations.gov. EPA finds that the revisions in R3 07-328 and reference to the Federal MACT standard adequately covers the repeal of this rule and does not signify backsliding within the SIP. Thus, EPA is proposing that R307-34 2 Qualifications of Contractors and Test Procedures for Vapor Recovery Systems for Gaso line Delivery Tanks be repealed from the Utah SIP and replaced by new R307-342 as d iscussed next.
J. R307-342, Adhesives and Sealants R307-342 is a new rule that establishes requirement s to limit VOC emissions from adhesives, sealants, primers and cleaning solv ents. R307-342 applies to any person who manufactures any adhesive, sealant, adhesive pr imer or sealant primer in Box Elder, Cache, Davis, Salt Lake, Utah or Weber counties and to any person who sells, supplies, or applies any adhesive, sealant, adhesive primer o r sealant primer in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah or Weber counties. T he emissions reductions are accomplished through prohibition of certain high VO C emitting products and practices. The rule limits product sales and use, and places r equirements on application and removal methods of the allowed products. There are some exe mptions consistent with the30

guidelines discussed in the next paragraph. The rul e also creates product labeling and recordkeeping requirements as part of rule complian ce. The rule, which sets maximum VOC content, is based on other guidelines and similar rules, including EPA issued CTG for Miscell aneous Industrial Adhesives, EPA453/R-08-005, September 2008. EPA developed its rec ommended approaches in the CTG based on the analysis of existing state and local e mission reduction approaches. Within DAQ’s TSD it is discussed that in 1998, the Califor nia Air Resources Board (CARB) issued a guidance document for the industry that wa s based on eight existing California air pollution control district rules. The Board det ermined that their guidance was RACT. In 2007, the Ozone Transport Commission (OTC) issue d a model rule for adhesives and sealants that was based on the 1998 RACT determinat ion. The model rule achieves VOC reductions through two basic components: sale and m anufacture restrictions that limit VOC content of specified adhesives, sealants and pr imers sold and use restrictions that apply to commercial/industrial applications. Area s ource VOC reduction occurs by reducing the availability of higher VOC content adh esives and sealants within the nonattainment areas. EPA notes that the VOC content limits are generally consistent with other state rules, for example BAAQMD rule 8-51-300 . DAQ estimates the costeffectiveness of Utah’s rule at $5730/ton in 2011 d ollars. R307-342, largely based on the OTC model rule, addr esses both these areas, and based on national product development programs with REs at 100%, consistent with use by other states (AirControlNET, 2006). Finally, the final rule is based on the most current OTC Model Rule which requires an overall capture an d control efficiency of at least 85% for any add-on emissions control systems operations . We note that this is more stringent31

than (for example) the 80% requirement in SCAQMD ru le 1168. DAQ submitted the new rule, R307-342 to EPA on Febr uary 18, 2014. The Board approved the new rule, R307-342 on February 6, 2013 , and the public comment period was held from March 1 to April 1, 2013. A public he aring was held on March 13, 2013. DAQ received written comments from industry pertain ing to the new proposed rule
R307-342. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-342, as well as in other similar area source rules, that control removal be based on the entire control system, and that tes t methods and recordkeeping requirements for the rules be expanded, on July 2, 2014, the Board proposed for public comment amendments to R307-342. The amendments incl uded language for control removal to be based on the entire control system an d for the inspection and recordkeeping requirements. A public comment period was held from August 1 to September 2, 2014. After the comment period, DAQ made a change to the proposed rule that included the addition of language “(excluding compounds not clas sified as VOC)” within R307-342- 6(2)(b). In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The proposed revisions were adopted by the Board on October 1, 2014 and was effective on December 1, 2014. Compliance with thes e revisions were required32

immediately. DAQ submitted these revisions to EPA o n December 9, 2014. The final rule contains applicable language to provide for suffici ent operating, testing, maintenance, reporting and recordkeeping requirements to allow p roper compliance verification and enforcement, as well as appropriate changes associa ted with our December 2, 2013 comment letter. Utah’s RACM and rule analysis can be found in the d ocket posted on regulations.gov. Additionally, EPA requested that D AQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s) and how the transfer efficiency is determined. The VOC definition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test met hod within Appendix A for this rule to follow. DAQ provided a clarification letter on A ugust 4, 2015 that specifies EPA Test Method 24 from 40 CFR part 60 Appendix A would be u sed for R307-342 and that the manufacturer certifies the transfer efficiency. EPA agrees with these clarifications and is proposing to approve the new rule, R307-342, and al so the subsequent revisions to this rule. Additionally, EPA is proposing that R307-342 currently constitutes RACM for the Nonattainment Areas for Adhesives and Sealants Oper ations for the Utah PM 2.5 SIP.
K. R307-343, Emissions Standards for Wood Furniture Ma nufacturing Operations R307-343 establishes requirements to limit VOC emis sions from wood furniture manufacturing. These emission reductions are accomp lished through limiting VOC content of coatings/materials used, establishing re quirements for application equipment, work practice and recordkeeping, and selection, ope ration and maintenance of add-on VOC control equipment and systems. R307-343 applies to wood furniture manufacturing33

operations, including related cleaning activities, that have the potential to emit 2.7 tons or more per year of VOCs and that are located in Box E lder, Cache, Davis, Salt Lake, Utah, Tooele, and Weber counties. The rule is based on the EPA CTG Control of VOC Emi ssions from Wood Furniture Manufacturing Operations, EPA 453/R-96-00 7, April 1996, as well as a review of similar current applicable California rules. Res ults from the evaluation of this rule in comparison to other coating rules resulted in the a pplicability being set to 2.7 tpy to gain further VOC reductions. VOC content limits are in-l ine with SCAQMD rules 1104 Wood Flat Stock Coating Operations and 1134 Wood Product s Coatings. The SJVAPCD rule 4606 was selected for the RACT comparative analysis . That rule requires an overall system efficiency of 85% and the same 85% requireme nt is proposed by Utah for any add-on emissions control systems operations. DAQ es timates a cost-effectiveness of $2,260/ton for this rule. On June 8, 2013 DAQ submitted revisions of R307-343 to the EPA. The Board proposed for public comment these revisions on Sept ember 5, 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. No public com ments were received. Sources in Salt Lake and Davis counties that have t he potential to emit between 2.7 and 24 tons of VOC per year was scheduled to be in compliance by September 1, 2013. Sources in Salt Lake and Davis counties that have the potential to emit 25 tons or more of VOC per year was to be in compliance by the effective date of this rule. All sources in Box Elder, Cache, Tooele, Utah, and Webe r counties were to be in compliance by January 1, 2014. The effective date of these rul e revisions was May 1, 201334 Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-343, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 7, 2014, the Board proposed for public comment amendments to R307-343. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter. In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of Rule R307-343 was effective De cember 1, 2014, and compliance was immediate. Utah’s RACM and rule anal ysis can be found in the docket posted on regulations.gov. The revisions to R307-343 found within the June 8, 2013 and December 9, 2014 submittals include changes to the rule applicabilit y from sources that have the potential to emit 25 tons VOC per year to 2.7 tons of VOC per ye ar and has been expanded to include all sources in Box Elder, Cache, Davis, Salt Lake, Utah, Tooele, and Weber counties. The definition section was updated to remove old defini tions and to add new ones. Sources35

are required to use a compliant coating method as d escribed in the new Table 1 or to use a control system method that achieves 85% or greate r VOC emissions reduction. A new section is added for application equipment requirem ents. This section requires all coatings to be applied using equipment that has a m inimum 65% transfer efficiency and establishes requirements for when conventional air spray methods may be used. A control system operations section is added. This section re quires owners and operators of emissions to operate and maintain control systems i n accordance with the manufacturer recommendations; to provide certification from the control system manufacturer that the emission control system will attain the required ef ficiency performance; and to maintain for two years records of operating and maintenance of the control system. A new section for work practices and recordkeeping is added that establish required control techniques to reduce VOC emissions. A compliance schedule was added and the methodology for determining capture efficiency was clarified. Remov al of sections that were obsolete. Additionally, EPA requested that DAQ clarify what V OC content test method would be used since the VOC definition found in R30 7-101-2 adopted and incorporated by reference 40 CFR 51.100(s) and how the transfer efficiency is determined. The VOC definition generally signifies test methods found i n 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ provided a clarification letter on August 4, 2015 t hat specifies EPA Test Method 24 from 40 CFR part 60 Appendix A would be used for R307-34 2 and that the manufacturer certifies the transfer efficiency. EPA agrees with these clarifications and is proposing approval of the revisions to R307-343 found within these two submittals, June 8, 2013 and December 9, 2014 and also that R307-343 current ly constitutes RACM for the36

Nonattainment and Maintenance Areas for Wood Furnit ure Manufacturing Operations for the Utah PM 2.5 SIP.
L. R307-344, Paper, Film, and Foil Coatings Rule R307-344 is a new individual rule created when R307-340 was repealed in its entirety. R307-344 establishes requirements to limit VOC emissions from roll, knife, and rotogravure coaters and drying ovens of paper, film, and foil coating operations. The emission reductions are accomplished through limiti ng VOC content of coatings/materials used, requirements for applicati on equipment, work practice and recordkeeping, and selection, operation and mainten ance of add-on VOC control equipment and systems. R307-344 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that hav e the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. The RACM analysis done for R307-344 was based on th e EPA CTG for Paper, Film, and Foil Coatings, EPA 453/R-07-003, Septembe r 2007. As background, in May 1977, EPA issued a CTG for surface coating on paper that was used in rulemaking for R307-340-5 and promulgated the new source performan ce standards (NSPS) in 1983 for coatings of pressure sensitive tape and labels, a s ubset of paper, film and foil. EPA promulgated the national emission standards for haz ardous air pollutants (NESHAP) in 2002 for paper and other web coating. EPA developed the recommendations in the 2007 CTG after reviewing the earlier CTG, the NSPS and N ESHAP. The VOC RACT limits were taken from the CTG, Table 1, page 18. Utah app lied the CTG-recommended 90% overall system efficiency for any add-on emissions control systems operations . DAQ estimates the cost-effectiveness of this rule at $1 440/ton in 2011 dollars.37 DAQ submitted the new Rule R307-344 to the EPA on M ay 9, 2013. The Board approved R307-344 for public comment on September 5 , 2012 and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012, and the EPA was the o nly commenter. Davis and Salt Lake counties were subject to R307-3 45 by the effective date and Box Elder, Cache, Tooele, Utah, and Weber counties were to be in compliance by January 1, 2014. The effective date of R307-345 was February 1, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-344, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-344. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter. In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of R307-344 was effective Decembe r 1, 2014, and compliance38

was immediate. On December 9, 2014, DAQ submitted t his final version of R307-344 to the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested that D AQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-344. EPA agrees with this clarificati on and is proposing approval of the new Rule R307-344, with subsequent revisions, and t hat R307-344 currently constitutes RACM for the Nonattainment and Maintenance Areas fo r Paper, Film, and Foil Coatings Operations for the Utah PM 2.5 SIP.
M. R307-345, Fabric and Vinyl Coatings Rule R307-345 is a new individual rule created when R307-340 was repealed in its entirety. R307-345 establishes requirements to limit VOC emissions from fabric and vinyl coating operations, which use roll, knife, or rotogravure coaters and drying ovens. The emission reductions are accomplished through li miting VOC content of coatings/materials used, requirements for applicati on equipment, work practice and recordkeeping, and selection, operation and mainten ance of add-on VOC control equipment and systems. R307-345 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that hav e the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. The RACM analysis done for R307-345 was based on th e EPA CTG, Surface39

Coating of Cans, Coils, Paper, Fabrics, Automobiles and Light-Duty Trucks, EPA 450/2- 77-008. However, as the CTG is aged (published in 1 977), DAQ also considered other state rules as part of the RACM analysis. The SCAQM D rule 1128 and the SJVAPCD rule 4607 were evaluated. Both rules include a VOC content limit of 2.2 lb/gal for these materials. DAQ chose to adopt the 2.2 lb/gal limit, phased in by January 1, 2015. The SJVAPCD rule 4607 is a comparable rule with a requi rement of 90% overall system efficiency, which Utah used for this rule for any add-on emissions control systems operations. DAQ estimates a cost-effectiveness of $ 3500/ton in current dollars. DAQ submitted the new Rule R307-345 to the EPA on M ay 9, 2013. The Board proposed R307-345 for public comment on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. EPA provided written comments, no other comments were received. Davis and Salt Lake counties were subject to this R 307-345 upon the effective date and Box Elder, Cache, Tooele, Utah, and Weber counties were to be in compliance by January 1, 2014. These revisions to R307-345 bec ame effective on February 1, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-345, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-345.

N. R307-346, Metal Furniture Surface Coatings Rule R307-346 is a new individual rule created when R307-340 was repealed in41

its entirety. R307-346 establishes requirements to limit VOC emissions from metal furniture surface coating operations in application areas, flash-off areas, and ovens of metal furniture coating lines involved in prime and top-coat or single coat operations. The emission reductions are accomplished through limiti ng VOC content of coatings/materials used, requirements for applicati on equipment, work practice and recordkeeping, and selection, operation and mainten ance of add-on VOC control equipment and systems. R307-346 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that hav e the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. There are exemptions to the requirements of R307-346 for stencil coatings, safe ty-indicating coatings, solid-film lubricants, electrical-insulating and thermal-condu cting coatings, touch-up and repair coatings, or coating applications utilizing hand-he ld aerosol cans. These exemptions are consistent with EPA CTG for Metal Furniture Coating s, EPA 453/R-07-005, September
2007. The RACM analysis done for R307-346 was based on th e EPA CTG for Metal Furniture Coatings, EPA 453/R-07-005, September 200 7. This CTG supersedes the original CTG published in 1977. EPA published the N SPS in 1982 and the NESHAP in 2003. The 2007 CTG incorporated recommendation from the first CTG, the NSPS and the NESHAP. DAQ chose to apply the limits directly from the CTG listed on page 23. These limits are similar to those in, for example, BAAQMD Rule 8-14-300. Utah has proposed applying the CTG recommended 90% overall s ystem efficiency for any add-on emissions control systems operations, which is more stringent than, for example, the 85% efficiency in BAAQMD Rule 8-14-302. DAQ estimates t he cost-effectiveness of this rule42

at $2020/ton in 2011 dollars. DAQ submitted the new Rule R307-346 to the EPA on M ay 9, 2013. The Board proposed for public comment R307-346 on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. EPA provided written comments, no other comments were received.

P. R307-348, Magnet Wire Coatings Rule R307-348 is a new individual rule created when R307-340 was repealed in its entirety. R307-348 establishes requirements to limit VOC emissions from ovens of magnet wire coating operations. The emission reduct ions are accomplished through limiting VOC content of coatings/materials used, re quirements for application equipment, work practice and recordkeeping, and selection, ope ration and maintenance of add-on VOC control equipment and systems. R307-348 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber cou nties that have the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. There are no EPA guidance documents (ACT or CTGs) t hat directly apply to this industry, so the RACM analysis done for R307-348 wa s based on a review and application of the following source materials. The NESHAP - Surface Coating of Miscellaneous Metal Parts and Products, FR Vol. 69, No. 1, January 2, 2004, applies to facilities with 10 tpy or more of any single hazard ous air pollutants (HAP) or 25 tpy or more of any combination of HAPs. While this NESHAP is not directly applicable, some components are similar, so DAQ used applicable cont rol efficiency and cost information47

from the NESHAP. The SCAQMD rule 1126 - coating lim its requires an overall system efficiency of 90%. Based on this California rule, U tah has proposed the VOC content limits and a 90% overall system efficiency for any add-on emissions control systems operations for R307-348. DAQ estimates the cost-eff ectiveness of this rule at $6560/ton
in 2011 dollars. DAQ submitted the new Rule R307-348 to the EPA on M ay 9, 2013. The Board proposed for public comment R307-348 on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. One industry source a nd the EPA provided written comments, no other comments were received. All sources in Davis and Salt Lake counties were su bject to this R307-348 upon the effective date and sources in Box Elder, Cache, Tooele, Utah, and Weber counties were to be in compliance by January 1, 2014. These revisions to R307-348 became effective on February 1, 2013.

Q. R307-349, Flat Wood Panel Coatings Rule R307-349 is a new individual rule created when R307-340 was repealed in its entirety. R307-349 establishes requirements to limit VOC emissions from flat wood paneling coating sources. The emission reductions a re accomplished through limiting49

VOC content of coatings/materials used, requirement s for application equipment, work practice and recordkeeping, and selection, operatio n and maintenance of add-on VOC control equipment and systems. R307-349 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber cou nties that have the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. The RACM analysis done for R307-349 was based on th e EPA CTG for Flat Wood Paneling Coatings, EPA 453/R-06-004, September 2006. This CTG supersedes the original CTG published in 1978. The CTG did include consideration of the NESHAPs issued in 2003. For all flat wood operations, the C TG recommends the use of a new limit of 2.1 lb VOC/gallon or an add-on control with 90% efficiency. DAQ also evaluated air quality rules in California. For example, the SJVAP CD Rule 4606 permits higher coating limits for a variety of categories. DAQ chose to am end the rule per the CTG using one coating limit across all categories, and has applie d the CTG-recommended 90% overall system efficiency for any add-on emissions control systems operations . DAQ estimates the cost-effectiveness of this rule at $2600/ton. DAQ submitted the new Rule R307-349 to the EPA on M ay 9, 2013. The Board proposed for public comment R307-349 on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. The EPA provided writ ten comments, no other comments were received. All sources in Davis and Salt Lake counties were su bject to R307-349 as of the effective date of this rule. Sources within Box Eld er, Cache, Tooele, Utah, and Weber counties were to be in compliance with R307-349 by January 1, 2014. The effective date50

for the new Rule R307-349 was February 1, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-349, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-349. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014.

R. R307-350, Miscellaneous Metal Parts and Products Co atings Rule R307-350 is a new individual rule created when R307-340 was repealed in its entirety. R307-350 establishes requirements to limit VOC emissions from miscellaneous metal parts and products coating oper ations. There are exemptions in R307-350-3 for items covered by other rules and cer tain special materials. The emissions reductions are accomplished through limiting VOC co ntent of coatings/materials used, requirements for application equipment, work practi ce and recordkeeping, and selection, operation and maintenance of add-on VOC control equ ipment and systems. R307-350 applies to sources located in Box Elder, Cache, Dav is, Salt Lake, Tooele, Utah and Weber counties that have the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. The RACM analysis done for R307-350 was based on th e EPA CTG for Miscellaneous Metal and Plastic Parts Coatings, EPA 453/R-08-003, September 2008. EPA published the NSPS in 1988 and an Alternate Con trol Techniques (ACT) document in 1994. Further, EPA promulgated a NESHAP in 2004. EPA developed the recommendations in the 2008 CTG after reviewing the cited references. DAQ chose to apply the VOC content limits recommended in the CTG on Table 2, page 33. Utah chose to apply the CTG-recommended 90% overall system eff iciency for any add-on emissions52

control systems operations. DAQ estimates the cost- effectiveness of this rule at $2020/ton in 2011 dollars. DAQ submitted the new Rule R307-350 to the EPA on M ay 9, 2013. The Board proposed for public comment R307-350 on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. Comments were receive d from the EPA and industry. The effective date of this new rule was February 1, 201 3. All sources within Davis and Salt Lake counties wer e to be in compliance with this new rule by September 1, 2013. All sources wit hin Box Elder, Cache, Tooele, Utah, and Weber counties were to be in compliance by Janu ary 1, 2014. After the rule was adopted by the Board in December 2012, a number of additional public concerns were provided to the DAQ from the regulated community. In those comments, the regulated community notified th e DAQ staff of technical difficulties they were having implementing the rule and also req uested that clarifications be made to the rule applicability. The primary difficulty conc erned military contractors who must meet military technical data orders that required c ertain specific materials not authorized by the rule. The Board proposed amendments to R307- 350 which were put out for public comment from August 1 to September 3, 2013. Several industry comments were received requesting further clarification. The Board determi ned that these comments were valid and adopted amendments to R307-350 on October 2, 20 13. DAQ submitted these revisions of R307-350 to the EP A on April 17, 2014. These revisions included clarification within the Applica bility and Exemption sections; adding and updating definitions; and other administrative changes. The Compliance Schedule53

was updated to read that all sources shall be in co mpliance with the requirements of R307-350 by January 1, 2014. These revisions became effective on December 3, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-350, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-350. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter. In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of Rule R307-350 was effective De cember 1, 2014, and compliance was immediate. On December 9, 2014, DAQ submitted this final version of R307-350 to the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested tha t DAQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test54

methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-350. EPA agrees with this clarificati on and is proposing to approve the new Rule R307-350, with subsequent revisions, and a lso that R307-350 currently constitutes RACM for the Miscellaneous Metal Parts and Products Coatings operations for the Utah PM 2.5 SIP.
S. R307-351, Graphic Arts Rule R307-351 is a new individual rule created when R307-340 was repealed in its entirety. R307-351 establishes requirements to limit VOC emissions from graphic arts printing operations. The emission reductions are ac complished through limiting VOC content of coatings/materials used, requirements fo r application equipment, work practice and recordkeeping, and selection, operation and mai ntenance of add-on VOC control equipment and systems. R307-351 applies to existing sources and new sources, with the lower emissions cut-off points for applicability ra nge from 25 tons/year to 2.7 tons/year VOCs, depending on the specific process, and includ es related cleaning activities. The RACM analysis done for R307-351 was based on tw o EPA CTG: the CTG for Offset Lithographic printing and Letterpress Pr inting, EPA 453/R-06-002, September 2006; and, the CTG for Flexible Package Printing, E PA 453/R-06-003, September 2006. EPA 453/R-06-002, September 2006, is based on findi ngs EPA made in their initial studies dating back to 1993. EPA 453/R-06-003, Sept ember 2006, incorporates the recommendations made in a CTG published in 1978 for rotogravure printing and flexible printing. The 1996 NESHAP for the printing and publ ishing industry is also given55

consideration in this CTG. The industry NESHAP has spurred significant coating reformulation nationwide, even though the NESHAP ta rgeted larger facilities. The DAQ applied the most current content limits from the CT G’s and also worked with the National Printing Association to update applicable portions to reflect current practices. DAQ estimates a cost-effectiveness of $5,890/ton of VOC removed in 2011 dollars. Based on this higher cost-effectiveness, DAQ set an applicability limit of 25 tons VOC per year (tpy), as compared with most of the other VOC rules, with an applicability limit of 2.7 tpy. DAQ submitted the new Rule R307-351 to the EPA on M ay 9, 2013. The Board proposed R307-351 for public comment on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. Comments were receive d from the EPA and industry. The compliance schedule for this new rule is that a ll sources within Salt Lake and Davis counties be in compliance with this rule by t he effective date of this rule and that all sources within Box Elder, Cache, Tooele, Utah, and Weber counties were to be in compliance by January 1, 2014. The effective date o f this new rule, R307-351, was February 1, 2013. Finally, a “Non-substantive Rule Amendment” was mad e by Utah to correct several incorrect subsection citations within the r ule. In accordance with Utah Code Title 19, Chapter 2, Air Conservation Act, Utah Code Titl e 63G, Chapter 3, Administrative Rulemaking Act, and Utah Administrative Code, R15, Administrative Rules, this change was made without public comment, as appropriate for a non-substantive change. The non-substantive changes made to R307-351-4 and R307 -351-2 were effective on56

February 15, 2013 and October 8, 2014, respectfully , and submitted to the EPA on May 20, 2014. Utah’s RACM and rule analysis can be found in the d ocket posted on regulations.gov. Additionally, EPA requested that D AQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-343. EPA agrees with this clarificati on and is proposing to approve the new Rule R307-351, with subsequent revisions, and a lso that R307-351 currently constitutes RACM for Graphic Arts operations for th e Utah PM 2.5 SIP.
T. R307-352, Metal Container, Closure, and Coil Coatin gs Rule R307-352 is a new individual rule created when R307-340 was repealed in its entirety. R307-352 establishes requirements to limit VOC emissions from metal container, closure, and coil coating operations. Th e emission reductions are accomplished through limiting VOC content of coatings/materials used, requirements for application equipment, work practice and recordkeeping, and sel ection, operation and maintenance of add-on VOC control equipment and systems. R307-352 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and We ber counties that have the potential to emit 2.7 tpy or more of VOC, including related c leaning activities. The RACM analysis done for R307-352 was based on th e EPA CTG, Surface Coating of Cans, Coils, Paper, Fabrics, Automobiles and Light-Duty Trucks, EPA 450/2-57

77-008. The CTG provided a comparative analysis of existing rules, and based on that analysis, DAQ used the BAAQMD Regulation 8, Rule 11 as the primary reference source, and the SCAQMD Rule 1125 as a secondary, fo r the development of this rule. The state is applying the same 90% overall system e fficiency requirement the BAAQMD used in Regulation 8 Rule 11 for any add-on emissions control systems operations . DAQ estimates a cost-effectiveness of $3,221/ton in 201 1 dollars. DAQ submitted the new Rule R307-352 to the EPA on M ay 9, 2013. The Board proposed R307-352 for public comment on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012 and the effective date for this new rule was February 1, 2013. The EPA provided written comments, no other c omments were received. The compliance schedule for R307-352 was for all so urces within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber co unties to be in compliance with this rule by January 1, 2014. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-352, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-352. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2013. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as58

appropriate changes associated with our December 2, 2013 comment letter. In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of Rule R307-352 was effective De cember 1, 2014, and compliance was immediate. On December 9, 2014, DAQ submitted this final version of R307-352 to the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested tha t DAQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-343. EPA agrees with this clarificati on and is proposing to approve the new Rule R307-352, with subsequent revisions, and a lso that R307-352 currently constitutes RACM for the Metal Container, Closure, and Coil Coatings operations for the Utah PM 2.5 SIP.
U. R307-353, Plastic Parts Coatings Rule R307-353 is a new rule that establishes requir ements to limit VOC emissions from plastic parts coating operations. There are ex emptions for certain special materials. The emission reductions are accomplished through li miting VOC content of59

coatings/materials used, requirements for applicati on equipment, work practice and recordkeeping, and selection, operation and mainten ance of add-on VOC control equipment and systems. R307-353 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and Weber counties that hav e the potential to emit 2.7 tpy or more of VOC, including related cleaning activities. The RACM analysis was based on the EPA CTG for Misc ellaneous Metal and Plastic Parts Coatings, EPA 453/R-08-003, September 2008. This guidance document provides a presumptive RACT. EPA promulgated a NESH AP in 2004. EPA developed the recommendations in the 2008 CTG after review of the NESHAP. The VOC content limits for R307-353 were taken directly from the CT G. Utah is applying the CTGrecommended 90% overall system efficiency for any add-on emissions control systems operations. DAQ estimates a cost-effectiveness of $ 2,020/ton in 2011 dollars. DAQ submitted the new Rule R307-353 to the EPA on J une 8, 2013. The Board proposed R307-353 for public comment on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. EPA noted that the CT Gs for Miscellaneous Metal and Plastic Parts Coatings, EPA 453/R-08-003 contains i ndustrial segments that were not included in the rule. Due to this DAQ modified the rule to include the missing coating limits and on December 5, 2012, the Board re-propos ed the rule for public comment on January 1 to January 31, 2013. No comments were rec eived, however, DAQ determined that a few minor changes were needed to clarify the Applicability section of the rule. The compliance schedule for R307-353 was for all so urces within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber co unties to be in compliance with the60

rule by January 1, 2014. R307-353 was effective on May 1, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-353, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-353. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter.

The final version of R307-353 was effective Decembe r 1, 2014, and compliance was immediate. On December 9, 2014, DAQ submitted t his final version of R307-353 to the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. EPA is proposing to approve the ne w Rule R307-353, with subsequent revisions, and also that R307-353 currently constit utes RACM for the Plastic Parts Coatings operations for the Utah PM 2.5 SIP.
V. R307-354, Automotive Refinishing Coatings61 Rule R307-354 is a new rule that establishes requir ements to limit VOC emissions from automotive refinishing operations. The emissio n reductions are accomplished through limiting VOC content of coatings/materials used, requirements for application equipment, work practice and recordkeeping, and sel ection, operation and maintenance of add-on VOC control equipment and systems. R307-354 applies to sources located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah and We ber counties that have the potential to emit 2.7 tpy or more of VOC, including related c leaning activities. The requirements of R307-354 do not apply to any canned aerosol coat ing products. The RACM analysis for R307-354 was based on the EPA CTG for VOC Emissions from Automobile Refinishing (EPA 450/3-88 -009, 1988/10) and ACT Document: Automotive Refinishing (EPA 453/R-94-031, 1994/04). These documents provide information on the application processes, V OC emissions and emission reductions, and costs associated with the use of al ternative coating formulations and equipment used in automotive refinishing operations . As 40 CFR Part 63, Subpart HHHHHH - NESHAP: Paint Stripping and Miscellaneous Surface Coating applies to all area sources, some aspects of the NESHAP were consi dered. Also, applicable portions of the OTC model rule, and the SCAQMD, and SJVAPCD aut omotive rules were utilized in developing R307-354. These documents do not provide a system efficiency recommendation; therefore, Utah is applying an over all system efficiency level of 90% for any add-on emissions control systems operations , which is near the expected level of reduction by applying low-VOC coatings. DAQ estimat es a cost-effectiveness of $2,740/ton. DAQ submitted the new Rule R307-354 to the EPA on M ay 9, 2013. The Board62

proposed R307-354 for public comment on September 5 , 2012, and the public comment period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. There were a number o f public and industry comments. The compliance schedule for R307-354 is for all sou rces within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber co unties were to be in compliance by January 1, 2014. The effective date of R307-354 was February 1, 2013. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-354, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-354. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter. In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of R307-354 was effective Decembe r 1, 2014, and compliance was immediate. On December 9, 2014, DAQ submitted t his final version of R307-354 to63

the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested that D AQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-343. EPA agrees with this clarificati on and is proposing to approve the new Rule R307-354, with subsequent revisions, and a lso that R307-354 currently constitutes RACM for the Automotive Refinishing Coa tings operations for the Utah
PM 2.5 SIP.
W. R307-355, Control of Emissions from Aerospace Manuf acture and Rework Facilities Rule R307-355 is a new rule that establishes requir ements to limit VOC emissions from aerospace coatings and adhesives, organic solv ent cleaning, and the storage and disposal of solvents and waste solvent materials as sociated with the use of aerospace coatings and adhesives. There are exceptions for cl eaning and coating associated with research and development, quality control, laborato ry testing and electronic parts and assemblies, (cleaning and coating of completed asse mblies are not exempt); in manufacturing or rework operations involving space vehicles; and, for rework operations performed on antique aerospace vehicles or componen ts. The emissions reductions are accomplished through limiting VOC content of coatin gs/materials used, requirements for application equipment, work practice and recordkeep ing, and selection, operation and64

maintenance of add-on VOC control equipment and sys tems. R307-355 applies to sources located in Box Elder, Cache, Davis, Salt La ke, Utah, Tooele and Weber counties that have the potential to emit 10 tpy or more of V OC, including related cleaning activities. The RACM analysis for R307-355 was based on the EPA CTG for VOC Emissions from Coating Operations at Aerospace Manu facturing and Rework Operations, EPA-453/R-97-004, December 1997. The CTG, Control o f Volatile Organic Compound Emissions from Coating Operations at Aerospace manu facturing and rework Operations, EPA-453/R-97-004, December 1997, page B-8, provides a model rule with a system efficiency of at least 81%. The model rule includes some exemptions that were not adopted in the proposed rule in order to gain great er VOC reductions. DAQ believes that EPA took great care working with industry to craft a RACM model rule and that DAQ should follow its requirements at a minimum. DAQ re viewed aerospace rules implemented by the State of Missouri and the SJVAPC D. Both of these jurisdictions crafted their rules generally along the EPA model r ule. The SJVAPCD rule 4605 was selected by Utah for the RACM comparative analysis. That rule requires a system efficiency of 85%. The Missouri rule 10CSR 10-5.295 was also used as a RACM comparative rule, and it requires the control syste m to reduce VOCs by 81%. Given the warehouse size operating areas common to these sour ces, it would be challenging at best to meet an efficiency value beyond 81%; therefore, Utah applied the EPA guidance value and the Missouri RACM value of 81%. DAQ submitted the new Rule R307-355 to the EPA on M ay 9, 2013. The Board proposed R307-355 for public comment on September 5 , 2012, and the public comment65

period was held from October 1 to November 1, 2012. Public hearings were held on October 15, 16, and 17, 2012. There were comments f rom industry and the EPA. The compliance schedule for R307-355 are for all so urces within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber co unties were to be in compliance by January 1, 2014. The effective date for R307-355 is February 1, 2013. A “Non-substantive Rule Amendment” was made by Utah to correct subsection R307-355-5 citation within the rule. The second (1) (d) was changed to (1)(e) to correct the numbering sequence. In accordance with Utah Cod e Title 19, Chapter 2, Air Conservation Act, Utah Code Title 63G, Chapter 3, A dministrative Rulemaking Act, and Utah Administrative Code, R15, Administrative Rules , this change was made without public comment, as appropriate for a non-substantiv e change. This non-substantive change was effective on February 15, 2013 and submi tted by DAQ to the EPA on May 20, 2014. Due to ongoing EPA concerns associated with the amo unt of control removal specified in R307-355, as well as in other similar area source rules, that control removal be based on the entire control system, and that the inspection and recordkeeping requirements for the rules be expanded before they could be approved, on July 2, 2014, the Board proposed for public comment amendments to R307-355. A public comment period was held from August 1 to September 2, 2014. The proposed amendments were adopted by the Board on October 1, 2014. The final rule contains applicable language to provide for sufficient operating, testing, maintena nce, reporting and recordkeeping requirements to allow proper compliance verificatio n and enforcement, as well as appropriate changes associated with our December 2, 2013 comment letter.66 In the “Add-On Controls Systems Operations” section it reads “An alternative test method may be substituted for the preceding test me thods after review and approval by the EPA Administrator.” EPA interprets this languag e to mean that such an alternate test method will be submitted by the State as a SIP revi sion that is subsequently approved by the EPA through the EPA public notice and SIP appro val process. The final version of Rule R307-355 was effective De cember 1, 2014, and compliance was immediate. On December 9, 2014, DAQ submitted this final version of R307-355 to the EPA. Utah’s RACM and rule analysis can be found in the docket posted on regulations.gov. Additionally, EPA requested tha t DAQ clarify what VOC content test method would be used since the VOC definition found in R307-101-2 adopted and incorporated by reference 40 CFR 51.100(s). This de finition generally signifies test methods found in 40 CFR part 60 Appendix A but does not provide a specific test method within Appendix A for this rule to follow. DAQ prov ided a clarification letter on August 4, 2015 that specifies EPA Test Method 24 from 40 C FR part 60 Appendix A would be used for R307-343. EPA agrees with this clarificati on and is proposing to approve the new Rule R307-355, with subsequent revisions, and a lso that R307-355 currently constitutes RACM for the Aerospace Manufacture and Rework Facilities operations for the Utah PM 2.5 SIP.
X. R307-356, Appliance Pilot Light Rule R307-356 is a new rule that establishes requir ements to limit VOC emissions from natural gas-fired fan-type central furnaces, g as fireplaces, and gas stoves. The emissions reductions are accomplished through prohi bition of any person from manufacturing for sale, distributing, selling, offe ring for sale, or installing any natural67

gas-fired fan-type central furnaces, gas fireplaces , or gas stoves that require the use of a continuous pilot light for ignition. Exemptions to the rule apply to units using a fuel other than natural gas, units used in recreational vehicl es, and units manufactured that are for shipment and use outside of the PM 2.5 nonattainment counties. R307-356 applies to manufacturers, distributors, retailers, and install ers of residential, institutional and commercial natural gas-fired fan-type central furna ces, fireplaces, stoves, and cooktops in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, a nd Weber counties. R307-356 is based on national product development p rograms, similar state rules and other guidelines. R307-356 achieves area source VOC reductions through sale and manufacture restrictions that restrict the ignition type of specified products within the nonattainment areas. Tools for DAQ inspectors to us e for compliance verification include review of production, shipment and installation rec ords, and inspection of product installations. DAQ estimates this rule should be co st-neutral, due to fuel savings. DAQ analysis of appliance type resulted in the foll owing apportionment. Most gas stoves/ranges (even low end units) now come wit h electronic ignition. It is assumed that pilot lighted ignition units are no longer mar ketable. DAQ assumed that 0% should be applied to the apportionment of all appliances. For furnaces, it is indicated that all homes have at least one, and that it is the predomi nate appliance in the home. Furnaces have a general life expectancy of 20 years, with re pairs favored over replacement due to replacement cost. Electronic ignition has become po pular in recent years. Because of their longevity and recent conversion to electronic ignition, it is assumed that all heaters use pilot light ignition that will be phased out in 10 years. DAQ assumed that 40% should be applied to the apportionment of all appliances. Each home has at least one water heater68

and it is the other predominate appliance in the ho me. DAQ assumed that 40% should be applied to the apportionment of all appliances. Wit h gas fireplaces pilot ignition is still common, and DAQ assumed that all units are pilot ig nition. DAQ assumed that 20% should be applied to the apportionment of all appli ances. On May 9, 2013, DAQ submitted the new Rule R307-356 to the EPA. The public comment period was held from September 1 to October 1, 2012, with a public hearing held on September 12, 2012. Comments were received from industry. Rule R307-356 was effective January 1, 2013. Any pe rson who manufactures for sale, distributes, sells, offers for sale, or insta lls any natural gas- fired fan-type central furnaces, gas fireplaces, or gas stoves that requir e the use of a continuous pilot light for ignition must be in compliance beginning January 1, 2014. Utah’s RACM and rule analysis can be found in the docket posted on regul ations.gov. EPA is proposing to approve the new Rule R307-356, with subsequent revi sions, and also that R307-356 currently constitutes RACM for Appliance Pilot Ligh ts for the Utah PM 2.5 SIP.
Y. R307-357, Consumer Products Rule R307-357 is a new rule that establishes requir ements to limit VOC emissions from consumer products. The emission reductions are accomplished through prohibition of certain VOC emitting products. R307-357 applies to any person who sells, supplies, offers for sale, distributes for sale, or manufactu res for sale consumer products for use in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, a nd Weber counties. The rule also creates product labeling and recordkeeping requirem ents as part of rule compliance. There are some limited exemptions consistent with t he EPA national rule promulgated in 1998 (40 CFR, Part 59, Subpart C), other states rul es, and certain products that have been69

granted an innovative products, or certain other ex emptions by the CARB as of the effective date of R307-357. The rule, which sets maximum VOC content for consum er products, is based on other guidelines and similar rules, including: The EPA national rule promulgated in 1998 (40 CFR, Part 59, Subpart C) for consumer products, the CARB rules, and the OTC Model Rule and OTC member states rules. The OTC rul es, which are the basis for the Utah rule, achieve additional VOC reductions over E PA’s national rule. R307-357 achieves VOC reductions through two basic component s: sale and manufacture restrictions that limit VOC content of specified co nsumer products. Area source VOC reduction occurs by reducing the availability of hi gher VOC content consumer products within the nonattainment areas. DAQ estimates the c ost-effectiveness of this rule to be $3000/ton. Any person who manufactures for sale, sells, suppli es, or offers for sale any of the applicable consumer products must be in compliance based on Table 1 in R307-357 beginning September 1, 2014 for the majority of pro ducts, and by January 1, 2015 or January 1, 2016 for the remaining products. Consume r products manufactured for shipment and use outside the specified counties are exempt from this rule. Tools for DAQ inspectors to use for compliance verification inclu de review of production and application records, labels of products used and in spection of application facilities. DAQ submitted the new Rule R307-357 to the EPA on F ebruary 18, 2014. The Board proposed for public comment on February 6, 20 12, and the public comment period was held from March 1 to April 1, 2012. A public he aring was held on March 13, 2012. Comments were received from the public, a community organization and industry. This70

rule became effective on August 1, 2013. A correction was made by Utah on March 5, 2014 to c orrect the percent VOC by weight for general purpose adhesives. This changes the VOC content limit for general purpose adhesives to the correct limit of ten perce nt (from 80, a typographical error), which is the content limit derived from the federal rule published at 63 FR 48831, Sept. 11, 1998, and as amended at 69 FR 18803, April 9, 2 004. The State also made other nonsubstantial changes to improve the formatting of the VOC-content limit table in the rule. A public comment period was held from April 1 , 2014 to May 1, 2014, during which no comments were received and no public heari ng was requested. These nonsubstantive changes were adopted by the Board on May 7, 2014 and became effective on May 29, 2014. The submittal for these nonsubstan tive changes was made by DAQ to the EPA on August 6, 2014. Utah’s RACM and rule analysis can be found in the d ocket posted on regulations.gov. EPA is proposing to approve the ne w Rule R307-357, with subsequent revisions, and also that R307-357 currently constit utes RACM for Consumer Products for the Utah PM 2.5 SIP.
Z. R307-361, Architectural Coatings R307-361 is a new rule that establishes requirement s to limit VOC emissions from architectural coatings. This rule applies to a ny person who supplies, sells, offers for sale, applies, or solicits the application of any a rchitectural coating, or who manufactures, blends or repackages any architectural coating for use within Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties. The em issions reductions are accomplished through limiting VOC content of coatings/materials used, storage, cleanup,71

recordkeeping, and labeling requirements. There are exemptions for certain special materials, quantity, and any architectural coating that is supplied, sold, offered for sale, or manufactured for use outside of the non-attainment counties. Test methods are provided for determining VOC content and certain exempt mate rials. The RACM analysis was based on the OTC model AIM ru le in developed in 2001 based on the work conducted by the CARB in 2000, th e CARB and several California air management districts architectural and industrial m aintenance (AIM) rules implemented in the late 1990’s-2000 based on RACT analysis and their updates, and the EPA national AIM rule promulgated in January 2005 (40 CFR Part 5 9 Subpart D). Area source VOC reduction occurs by reducing the availability of hi gher VOC architectural coatings within the nonattainment areas. DAQ cited an initial cost of $6,628 per ton for the OTC model rule; DAQ reasoned that the current cost-effectiven ess would be substantially lower given that the initial capital costs had already be en realized. Any person who supplies, sells, offers for sale, ap plies, or solicits the application of any architectural coating, or who manufactures, blends or repackages any architectural coating must be in compliance by January 1, 2015. A coating manufactured prior to January 1, 2015, may be sold, supplied, or offered for sale for up to three years after January 1, 2015, and a coating manufactured before January 1, 2015, may be applied at any time. Tools for DAQ inspectors to use for compl iance verification include review of production and application records, labels of produ cts used and inspection of application methods. DAQ submitted the new Rule R307-361 to the EPA on F ebruary 18, 2014. The Board proposed R307-361 for public comment on June 5, 2013, and the public comment72

period was held from July 1 to July 31, 2013. Comme nts were received from the public, a community organization and industry. Rule R307-361 was effective October 31, 2013. Utah’ s RACM and rule analysis can be found in the docket posted on regulations.go v. EPA is proposing to approve the new Rule R307-361, with subsequent revisions, and a lso that R307-361 currently constitutes RACM for Architectural Coatings for the Utah PM 2.5 SIP.
VI. Proposed Action EPA is proposing approval of the revisions to Admin istrative Rules R307-101-2 and R307-103, along with the additions/revisions/re peals in R307-300 Series; Requirements for Specific Locations (Within Nonatta inment and Maintenance Areas), R307-303, R307-307, R307-312 (conditionally approve d, see below), R307-335, R307- 340 (repealed), R307-342 (repealed and replaced), R 307-343, R307-344, R307-345, R307-346, R307-347, R307-348, R307-349, R307-350, R 307-351, R307-352, R307-353, R307-354, R307-355, R307-356, R307-357, and R307-36 1 for incorporation to the Utah SIP as submitted by the State of Utah on May 9, 201 3, June 8, 2013, February 18, 2014, April 17, 2014, May 20, 2014, July 10, 2014, August 6, 2014, and December 9, 2014. We are proposing to approve Utah’s determination that the above rules in R307-300 Series; Requirements for Specific Locations (Within Nonatta inment and Maintenance Areas) constitute RACM for the Utah PM 2.5 SIP for the specific source categories addressed; however, we are not proposing to determine that Uta h’s PM 2.5 attainment plan has met all requirements regarding RACM under subparts 1 and 4 of Part D, title I of the Act. We intend to act separately on the remainder of Utah’s PM 2.5 attainment plan. EPA is proposing to conditionally approve revisions to R307-312 and R307-328.73

Additionally, EPA is proposing to conditionally app rove Utah’s determination that R307- 312 constitutes RACM for the Utah PM 2.5 SIP for aggregate processing operations. As stated above, we are not proposing to determine tha t Utah’s PM 2.5 attainment plan has met all requirements regarding RACM under subparts 1 and 4 of Part D, title I of the Act. Under section 110(k)(4) of the Act, EPA may approve a SIP revision based on a commitment by the State to adopt specific enforceab le measures by a date certain, but not later than one year after the date of approval of t he plan revision. On August 4, 2015, Utah submitted a commitment letter to adopt and sub mit specific revisions within one year of our final action on these submittals; speci fically to remove the phrase “or equivalent method” in one rule and to specify three equivalent methods in the other rule. If we finalize our proposed conditional approval, U tah must adopt and submit the specific revisions it has committed to within one year of ou r finalization. If Utah does not submit these revisions within one year, or if we find Utah ’s revisions to be incomplete, or we disapprove Utah’s revisions, this conditional appro val will convert to a disapproval. If any of these occur and our conditional approvals co nvert to a disapproval, that will constitute a disapproval of a required plan element under part D of title I of the Act, which starts an 18-month clock for sanctions, see C AA section 179(a)(2), and the twoyear clock for a federal implementation plan (FIP), see CAA section 110(c)(1)(B). Finally, EPA is proposing to approve the repeal of R307-342, Qualification of Contractors and Test Procedures for Vapor Recovery Systems for Gasoline Delivery Tanks, submitted by DAQ on February 2, 2012.
