- To correct typographical or other clerical errors; make minor grammatical changes to improve re adability or clarity; modify th e format, numbering, order, ca pitalization, punctuati on, or syntax of certain text to increase standardization within and among rules; and make various other minor changes of a purely editorial nature. As thes e proposed changes do notalter the sense, meaning, or effect of the rule , they are not described in detail here, but can be readily discerned in the “strikeout and under line” version of the rule contained in Item # 6 of this notice. A.R.S. § 49-471.08(A)(2): Written finding by the Control Officer setti ng forth the reasons why the rule or ordi nance making is necess ary and does not alt er the sense, meaning or effect of the federal or state rule or law from which it is derived. This rulemaking is required to u pdate the applicability da tes in these rules. It incorporates subparts that have been passed bythe federal government which are required to be implemented by the department. Rules 321, 360, 370, 371, and Appe ndix G do not alter the sense, meaning or effect of the state rule s and federal regulations from which they are derived, as they incorporate language t hat is essentially the same as the state's applicablerules and the federal code of regulations.

### County Notices According to A.R.S. § 49-112
The purpose of this rulemaking is to update the Maricopa County Air Qu ality Department’s (department’s) New Source Review (NSR) rules in order to secure their approva l as part of the state implementation plan(SIP) under the federal Clean Air Act. T he update will be consistent with revisions the Arizona Department of Environmental Quality (ADEQ) and the U.S. Environmental Protection Agency (EPA) made to the NSR Program required by the federal Clean Air Act (CAA). The proposed amendments included in the rule making consist of extensive revisions to th e county’s major NSR program as well as new NSR requirements for minor sources and minor modifications de signed to protect the national ambient air quality standards (NAAQS). (Whether a source or m odification is major or mi nor depends on the level of emissions , as described ingreater detail below.) There is currently a significant discrepanc y, known as the “SIP gap,” between the NSR rules as set forth in the Maricopa CountyAir Pollution Control Regulations and the rules that have been approved by the EPA into the Maricopa County portion of the Arizona SIP. Once approved, the amended rules will eliminate the SIP gap. This rulemaking also includes proposed confor ming and technical changes to rules related to NSR, such as requirements for the g eneral permit program. Background: Clean Air Act NS R Requirements Section 110(a)(2)(C) of the federal Cl ean Air Act (the “Act” or “CAA”), 42 U.S.C. 7410(a)(2)(C), requires SIPs to: include a program to provide for the ... regul ation of the modification and construction of any stat ionary source within the area s covered by the plan as necessary to assu re that national ambient air quality standards are achiev ed, including a permit program as required in parts C and D of this subchapter ... . Because regulati ons adopted under this section apply to newly constructed and modified, as opposed to existing, sources they ar e commonly referred to as “new source review” programs. Part C of title I of the Act, 42 U.S.C. 7470-7492, establishes the NSR re quirements for major sources that are constructed or m odified in areas that have attained the NAAQS for one or more criteria polluta nts (ozone, carbon monoxide, nitrogen dioxide, sulfur dio xide, PM10, PM2.5 and lead). Sources th at belong to the list of categories set forth in section 169(1) of the Act, 42 U.S.C. 7479(1), are major if they emit or have the potential to emit 100 or more tons per year of a regulated ai r pollutant. Other sources are subj ect to a 250 tons per year threshold. The program required by Part C is known as “Prevention of Signifi cant Deterioration” (PSD) because its purpose is to prevent ai r quality in attainment areas from deteriorating to the level of th e NAAQS. See CAA § 160. PSD, ther efore, establishes or require s EPA to establish maximum allowable increases, known as “increments,” over exis ting concentrations of criteria pollutants and requires permit applicants subject to PSD to demonstrate that a new source or modi fication’s emissions will not result in a vio lation of the increments or the NAAQS. PSD also requires the installation of the Best Avai lable Control Technology (BACT), defined as “the maximum degree of reduction of each pollutant subject to regulation under this ch apter emitted from or which results from any major emitting faci lity, which the permitting authority, on a case-by-case basis, taking into account energy, environmental, an d economic impacts and other co sts, determines is achievable fo r such facility.” 42 U.S.C. 7479(3). Part D of Title I establishes NSR requireme nts for major sources and modi fications in nonattainment ar eas. Under Subpart 1 of P art D, 42 U.S.C. 7501-7509a, a major source is defi ned as any source that emit s or has the potential to emit 100 tons per year or m ore of a pollutant for which an area has been de signated nonattainment. Subpart 2 of Part D, 42 U.S.C. 7511-7511f, establishes lower m ajor source thresholds for certain ozone, carbon monoxide and PM10 nonattainment areas. Permit applicants subject to Part D must demonstrate that a majo r source or modification will comply with the lowest achievable emission rate (LAER) and that re ductions in emissions from the samesource or other sources will offset any emissions increases from the source or modification. In addition to requiring compliance with the specific major NS R requirements of Parts C and D, section 110(a)(2)(C), 7410(a)(2) (C), requires “regulation of the modifi cation and construction of any st ationary source within the ar eas covered by the plan as nece ssary to assure that national ambient air quality st andards are achieved.” (Empha sis added.) EPA refers to 110(a)(2)(C) programs that ap ply to non-major sources and to minor modifications to major source s as “minor NSR.” 76 Fed. Reg. 38748, 38752 (July 1, 2011). EPA NSR Regulations EPA has promulgated regulations establishing the elements a state program must contain to satisfy section 110(a)(2)(C) at 40 CF R 51, Subpart I (§§ 51.160-51.166) and fe deral implementation plans at 40 CFR 52 § 52.21 and 40 CFR 51, Appendix S. Sections 51.165 and 51.166 establish the re quirements for nonattainment NSR and PSD programs, respectively. These rules are

### County Notices According to A.R.S. § 49-112

1304 Vol. 21, Issue 31 | Published by the Arizona Secretary of State |July 31, 2015 highly detailed and restrictive. States se eking approval of major NSR programs must eith er strictly conform to these rules or d emonstrate that any deviations are at least as stringent as EPA’s program. Both § 51.165 and 51.166 limit the applicabili ty of major NSR to the construction of a new major source or a “major modificatio n” to a major source. A major modification is define d as a physical or operational change that will result in both a significant incr ease and a significant net increase in the em issions of a regulated NSR pollutant. For criteria pollutants and their prec ursors, “significant ” is defined as: Carbon monoxide 100 tons per year (tpy) Nitrogen oxides 40 tpy Sulfur dioxide 40 tpy Volatile organic compounds 40 tpy Lead 0.6 tpy PM10 15 tpy PM2.5 10 tpy As EPA has noted, the “Federal regulations for minor source programs [at 40 CF R 51.160-164] are considerab ly less detailed thanthe requirements for major sources.” 71 Fed. Reg. 48696, 48700 (Aug. 21, 2006). Under the minor NSR regulations, a state program must contain “legally enforceable procedures” to prevent the cons truction or modification of a minor source if it will “result in a violation of applicable portions of the control strategy” for compliance with th e NAAQS or “interfere with the attainment or maint enance of a” NAAQS. 40 CFR 51.160. A minor NSR program need not apply to all ne w and modified sources, but it must “ide ntify types and sizes of facilities, buildi ngs, structures, or installations which will be subject to” minor NSR and “discuss the basis for determining which facilities will b e subject to review.” 40 CFR 51.161( e). As EPA has noted: Applicability thresholds are proper in [a minor NSR program] pr ovided that the sources and modi fications with emissions below the thresholds are inconsequentia l to attainment and maintenance of the NAAQS . 71 Fed. Reg. 48701. The appropriate threshold levels for NSR a pplicability are often referred to as “de mi nimis” levels. The program must allow a m inimum 30-day period to comment on the applicant’s minor NSR appl ication and the agency’s proposed decision. 40 CFR 51.161. Maricopa County’s NSR SIP and Current NSR Rules Before the department’s creation in 2004, Maricopa County’s Bureau of Air Pollution Control was responsible for administering Maricopa County’s air quality program and the Board of Supervis ors adopted its original major and minor NSR rules. Maricopa County implemented NSR through an installation permit program, whic h required owners and operators to obtain an installation pe rmit before beginning construction of a new so urce or a modification to an existing source. See former Maricopa County Bureau of Air Pollution Control Regulation Rule 21, wh ich, along with other rules cited in this discussion, can be found at EPA Region 9’ s web site at: http://www2. epa.gov/aboutepa/epa-regi on-9-pacific-southwest . A separate operating permit wa s required before the owner or operator was allowed to begi n operation of the source or modification. See former Rule 220 Permits to Operate. In 1988, EPA approved the Maricopa County nonattainment NSR provisions into th e SIP. 53 Fed. Reg. 30220 (Aug. 10, 1988). Effective November 22,1993, EPA delegated PSD authority to Maricopa County via a PSD Delegation Agreement. 59 FR 1730 (January 12, 1994). The SIP Gap EPA last approved revisions to the Mari copa County NSR SIP in 1988. See 53 Fed. Reg. 30220 (Aug. 10, 1988). Since the amendments last approved by EPA were adopted, the county ha s re-organized forming the MaricopaCounty Air Quality Department and has made substantial re visions to the program. Most significantly, in 1992 through 1993, the Arizona State adopted legisl ation, followed by conformi ng rule amendments, to mov e from the old installation and operating permit program to a “unitary” program that authorizes both constr uction and operation i n a single permit. NSR require ments for new sources are now enforced as part of the issuance of a single permit that also ensures c ompliance with all other applicable requirements of state and federal air quality laws. For major sources, thes e permits are designe d to comply with title V of the Act, as well as Parts C and D of title I. Ma jor modifications subject to major NSR now require a signif icant revision to the permit for an existing source, rather than a ne w installation permit. Other modi fications that formerly require d an installation permit may now proceed under eith er a significant or minor permit revision.July 31, 2015 | Published by the Arizona Secretary of State | Vol. 21, Issue 31

In addition to adopting the uni tary permit program, MaricopaCounty also has updated its NSR rules to incorporate: - the PM 10 and PM 2.5 NAAQS, - the PM 10 increments, - the nitrogen dioxide increments, - the 1997 eight-hour ozone NAAQS, - the “WEPCO” rule redefining the method for determining whethe r a modification to an electric generating un it is major, and - various technical amendments. None of these changes is included in th e approved NSR SIP for Maricopa County. Under federal law, Maricopa C ounty remains obligated to conti nue enforcing the old NSR programuntil EPA approves the new one. Fortunately, the new program is in most cases more stringent than the old, so that compliance with current rules is largely suf ficient to assure compliance with the approved NSR SIP. There are a few inst ances, however, in which the ol d rules require review procedur es that go beyond the current program. Maricopa County has had to is sue guidance explaining that in these cases the department wil l apply the approved SIP, rather than the current rules. It would obviously be preferable for the re quirements of the SIP and the current rules to match. Maricopa County is, therefore, seeking through these proposed rule amendments to eliminate the SIP gap fo r the permit program. EPA Amendments to Major NSR Maricopa County has attempted to secure EPA approval of prior versions of its NS R rules, but so far without success. Since Mari copa County last updated its NSR rules, EPA has adopted substantial re visions to the major NSR progr am, making additional amendments necessary before approval by EPA can be secured. Most significantly, on December 31, 2002, EPA promulgated comp rehensive amendments , known as “NSR reform,” to the regulatory methods for determining whether a ma jor modification has occurred. 67 Fed. Reg. 80186. On June 24, 2005, the United States Court of Appeals for the D.C. Circuit vacate d some of the rule changes, including exem ptions for modificati ons to certain “clean units” and modifications that qualify as “pollution control projects.” New York v. EPA, 413 F.3d 3 (D.C. Cir 2005). The remaini ng rules, which remain in effect, consist of changes to the method for calculating the emissions increase from a modification to an existing emissions unit and provisions for “Plantwide Applicability Limits” (PALs). The determination of whether a modification to an existing unit will result in a signifi cant emissions increase entails a comparison between “baseline” (i.e. existing) emissions and future emissions after the modification is complete. (The installation of a ne w unit is generally deemed to result in an increase equal to the unit’s pot ential to emit.) NSR reform es tablished a new method for deter mining baseline emissions and a new option for determining future emis sions for modifications to existing units. Under pre-NSR Reform rules, base line emissions were generally calc ulated using the actual emissi ons for the two-year period imm ediately preceding the proposed change. 67 Fe d. Reg. 80188. As EPA has noted, regulated industries complained that this method p rovided only “limited abili ty to consider the operational fluctuations associat ed with normal business cycles.” 67 Fed. Reg. 8019 1. The NSR Reform amendments therefore allow the use of any consecut ive 24-month period during the ten- year period prior to the change to establish baseline actu al emissions. (A fi ve- year period is used for EGUs.) Before NSR Reform, an existing unit’s future, post-modifi cation emissions were normally deemed to equal the unit’s potential to emit (PTE). The definition of PTE assumes that a unit “will operate at its full capacity year round,” unless the source’s permi t includes “enforceable restrictions on the unit’s operation.” This was pr oblematic, because “using PT E as a measure of post-chan ge emissions automatically attributes all possible emissions increa ses to the change.” In many case s, however, the unit might “fun ction essentially as it did be fore the change” and produce no increa se or a less-than-significant in crease in actual emissions. 67 Fe d. Reg. 80193-94. After NSR Reform, a source’s owner or opera tor may now elect to use an existing unit’s “projected actual emissions,” rather tha n its PTE, to determine future emissions. Unlike PTE, a unit’s projecte d actual emissions take into account historic al operational data and exclude emissions that c ould have been accommodate d before the modification. According to EPA, this new test for calculating the emissions increase from a modifi cation to an existing unit, known as the “actualto-projected-actual” test , will produce bene fits for regulated industries, the envi ronment and state and local agencies: By allowing you [i.e., regulated entities] to use today’s new version of the actual-to- projected-actual appl icability test to e valuate modified existing emis sions units, we expect th at fewer projects will trigger the ma jor NSR permitting re quirements. None-

1306 Vol. 21, Issue 31 | Published by the Arizona Secretary of State |July 31, 2015 theless, we believe that the environment w ill not be adversely affected by these changes and in some respects will benefit from these changes. The new test wi ll remove disincenti ves that discourage source s from making the types of changes that improve operating efficiency, implement pollution prev ention projects, and result in other environmentally be neficial changes. Moreover , the end result is that State and local re viewing authorities can appropriately focus their limited resources on those activitie s that could cause real and signi ficant increases in pollution. 67 Fed. Reg. 80192. The NSR Reform rule also provides that if there is a “reasonabl e possibility” that modifications to existing emissions units wi ll produce a significant em issions increase of a regulated NSR pollutant, and the owner or operator elects to use the actual-to-proje ctedactual test, the modifications will be subject to monitoring, recordkeepi ng and reporting obligations. The initial NSR Reform rule did not define “reasonable possi bility.” The court in New York v. EPA held that wi thout a definitio n or other clarification, the rule failed to provide regulated entitie s or agencies adequate notice of when these obligations are triggered. In response, EPA issued amendments to its major NSR rules defining the term. 72 Fed. Reg. 72607 (Dec. 12, 2007). Although EPA subsequently granted a petition to reconsider the definition, it did not stay the provision, whic h therefore remains in effect. The other major element of NSR Reform is the PAL, which allo ws major sources to avoid majo r NSR by accepting and complying with a source-wide cap on emissions. PALs are set for each regulat ed NSR pollutant at a level equa l to baseline actual emission s plus the significant level for the pollutant. Baseline actual emissions are calculated in the same wa y as described above for calcul ating emission increases from modificati ons to existing emission units. A source may generally make any changes it wants without trig gering major NSR, so long as plantwide emissions after the change remain below the PAL. PALs last for ten ye ars and are renewable. EPA believes that regulated entities “will benefit from the PAL option because [they] will have increased operational flexibili ty and regulatory certainty, a simpler NS R applicability approach, and fe wer administrative burdens.” 67 Fed. Reg. 80206. Based on a review of six flexible permit pilot projects, EPA c oncluded that the environment would also benefit. According to the agency, “ PALs will over time tend to shift growth in emissions to cleaner uni ts, because the growth will have to be accommodated under the PA L cap.” 67 Fed. Reg. 80207. Since the last Maricopa County update, EPA also has made numerous revisions to the NAAQS. The NAAQS are not technically part of EPA’s NSR regulations, but in order to be approvable, a state NSR program must allow for enforcement of the current version of these standards. See, e.g., 40 CFR 51.166( k)(1). Maricopa County must also update Rule 510 to reflect the revised NAAQS. Finally, EPA has made numerous other revisions that must be included in the Maricopa County program, such as the adoption of PM 2.5 increments and significant impa ct levels and signi ficant monitoring c oncentrations for PM 2.5 . Discussion About This Rulemaking: Consistent with the Maricopa County obligation under A.R.S. § 49-480(B), the de partment is proposing to adopt NSR amendments that are substantially identical to the ADEQ and EPA NSR progr ams for major sources and amendm ents that generally impose no greater procedural burden than ADEQ’s procedures for minor source s. However, due to long-stand ing nonattainment area federal requirements, Maricopa County’s permitting thresholds are lower than ADEQ’s pe rmitting thresholds. Unde r A.R.S. § 49-479(C), a county may not adopt a rule or ordinance that is more stringen t than the rules adopted by ADEQ for similar sources unless it de monstrates compliance with the appl icable requirements of A.R.S. §49-112. Under § 49-112(A), the county may adopt a rule that is m ore stringent than or in addition to a provisi on of A.R.S. Title 49 or an ADEQ rule under specific c onditions including peculiar lo cal conditions, necessary to prevent a si gnificant threat to public heal th or environment, or require d under a federal statute or regu lation. A further discussion of complian ce with A.R.S. §49-112 can be found in Item 6 of this Notice of Proposed Rulemaking. Revisions to Maricopa County Major NSR Program EPA’s major NSR regulations are quite detailed and restrictive. They estab lish a specific body of “c orresponding federal law th at addresses the same subject matter” as the major NSR amendments. The amendments included inthe ADEQ-NSR rulemaking consisted of those required under HB 2617 1 and ensured that the major NSR program ame ndments were consiste nt with and no more 

### 1. HB 2617 which became law on July 29, 2010, required thatADEQ as set forth in A.R.S. § 49-104(A): 17. Unless specifically authorized by the legislature, [the department shall] ensu re that state laws, rules, standards, permits , variances and orders are adopted and construed to be consiste nt with and no more stringent than the corresponding federal law that addresses the same subject matter. This provision shall not be construed to adversely af fect standards adopted by an Indian tribe under federal law.

stringent than the corresponding EP A regulations. Consistent with that obligation, Maricopa County is proposing to adopt major NSR amendments that incorporate by reference most of the federal rule s. Incorporation by re ference will result in rules substantial ly identical to the ADEQ rulemaking desc ribed above. Specific ally, these proposed provisions will eliminate a provision from the exist ing definition of major source beca use it was more stringent thanthe corresponding federa l definition. In addition, the incorporat ion by reference of the federal definiti ons would be substantially identical to the sense, meaning, and effect of ADE Q’s definitions a s required by A.R.S. § 49-471.08(B). Maricopa County Minor NSR Requirements The proposed rule amendments relating to mi nor NSR included in this rulemaking are desi gned to address a lack of explicit proce

dures designed “to assure that national ambient air quality st andards are achieved,” as requir ed by CAA § 110(a)(2)(C). Maricop a County’s current minor source permitting rule s require the inclusion of “[e]nforceable emission limitations and standards, incl uding operational requirements and limitations that ensure complian ce with all applicable requirements.” Rule 220, Se ction 302.2. The y therefore satisfy the requirement in EPA’s minor NSR rules to as sure that minor sources do not vi olate “applicable portions of the control strategy.” Another propos ed revision adds procedures re lated to stack heights, includi ng good engineering practice (GEP ) stack height provisions as required by 40 CF R 51.164 in Rule 200. MCAQD does not believ e that many, if any, minor sources will trigger the stack he ight requirements. Maricopa County's permit rules fo r minor NSR impose no greater procedural burden than procedures for th e review, issuance, revi

sion and administration of permits issued by the State. However, Maricopa County's rules and pro cedures contain requirements sp ecific to nonattainment area stat us, increment consumption analysis and impacts on nearby nonattai nment areas. These requirement s result in permit conditi ons that address the sour ce's proximity to the PM 10 and ozone nonattainment areas, specific atmospheric and geographical conditions found at the source 's location, control technol ogy provisions required by the CAA for nonattainment are as, and other control measures adopted into various nonattainment SIPs for Maricopa County. Specifically , various SIPs for Maricopa County have required the adopti on of reasonably available control technology (RACT), best ava ilable control technology (BACT), and most stringent measures (MSM) as required by CAA §§ 172, 182, 188, and 189. As a result of long-standing nonattainment classifications for ozone and particulates, Maricopa C ounty has existing permit thre sholds that are lower than ADEQ’s in order to address the emissions sources specific to the county that contribute to nonattainment an d are subject to the county’s numerous source-specific emission control rules. In this action, th e county proposes to maintain the cu rrent permit threshold but conve rt all thresholds from pounds per day to tons per year. The permit threshol ds are proposed to be:

Given the lower permit thresholds and the number of source-specific emis sion control rules in place to address county nonattainment areas, Maricopa County also pr oposes to define permit thres holds that would trigger minor NSR modifications as follows: Pollutant Uncontrolled Emission Rate In Tons Per Year (TPY) PM 2.5 (primary emissions only; levels for precursors are set below) 0.5 PM 10 0.5 SO 2 1.0 NO x 1.0 VOC 0.5 CO 1.0 Pb 0.3 Single HAP (other than Pb) 0.5 Total HAPs 1.0 Any other regulated air pollutant 1.0

Th e county procedures wer e adopted in March 2000 following a Stakehol der process with input from both regulated sources and non-governmental organizations

The county procedures require the following: - Posting the receipt of all applications on the department’s website once a week as they are received, - Allowing the public to reque st a public hearing on a ny application posted to the website at any time after the initial post, - Providing a formal 30-day public notice publ ished in the newspaper and posted online fo r larger, more envi ronmentally significant sources, and - Once a month, publishing in a news paper and posting online a list of permits issued that month. In this rulemaking, the departme nt also proposes to convert the public participation thresholds to the following tons per year bases from the current triggers thatrely on Rule 280 fee tables:

### County Notices According to A.R.S. § 49-112

1310 Vol. 21, Issue 31 | Published by the Arizona Secretary of State |July 31, 2015 Major NSR: The department is proposing to incorporate portions of the federal nonatt ainment NSR rule requirement s into Maricopa County Air Pollution Control Regulations Rule 240 by incorporating the fede ral requirements by refe rence. The proposed amendments to the department’s major NSR program include: - The determination of whether a modification to an existing uni t will result in a significant emissions increase, which entail s a comparison between “baseline”, i.e., exis ting, emissions and future emissions after the modification is complete. - The allowance of the use of any consecutive 24-month period during the te n-year period prior to the change to establish basel ine actual emissions (a five-year pe riod for electric generating units). - The allowance to use an existing unit’s “projected actual emissi ons,” rather than its potential to emit (PTE), to determine f uture emissions. Unlike PTE, a unit’s pr ojected actual emissions take into account historical operati onal data and exclude emissions that could have been accommodate d before the modification. This new test for calculating the emi ssions increase from a modification to an existing unit, known as the “act ual-to-projected” test, will produce benefits for regul ated industries, the enviro nment and state and local agencies. If there is a “reasonable possibility” th at modifications to existi ng emissions uni ts will produc e a significant emissions increase of a regulated NSR pollutant and the owner or operator elects to use the actual-to-projected-act ual test, the modifications will be subject to mo nitoring, recordkeeping and reporting obligations. - Plantwide applicability limitations (PALs). PALs allow major sources to avoid major NSR by ac cepting and complying with a source-wide cap on emissions. PALs are set fo r each regulated NSR pollutant at a level equal to baseline ac tual emissions plus the significant level for the pollutant. A source may generally make any change it wa nts without triggering major NSR, so long as plantwide emissions after the change remain below the PAL. PALs last for te n years and are renewable. - The allowance of limited interpollutant emission offsets for precursor pollutants on a case by case basis, except for PM 10 and PM 2.5 . Any interpollutant emission offs ets used at a major stationary source must receive written approva l by EPA. As EPA has approved a demonstration that PM 10 precursors do not cont ribute significantly to PM 10 violations in Maricopa County (67 FR 48734, July 25, 2002), interpollutant offsets are not allowed between PM 10 and PM 10 precursors. In addition, interpollutant offsets between PM 2.5 and PM 2.5 precursors are not allowed unl ess modeling has been used to demonstrate appropriate PM 2.5 interpollutant offset ratios as approved in a PM 2.5 Attainment Plan. Minor NSR: The department is proposing amendments in the following rules to addr ess Minor NSR: Rule 200 (Permit Requirements), Rule 220 (Non-Title V Permit Provisi ons), Rule 230 (General Permits), Rule 241 (propos ed new title: Minor New Source Review (NSR)), Appendix D (List Of Insignificant Activities), and Appendix E (L ist Of Trivial Activities). The amendments include the following: - Retention of existing permitting exemption thresholds but conversion of default emission- based provision from lbs/day to an annual quantity. - Use the emission-based thresholds for minor NSR modi fication threshold:

 Current permitting thresholds ar e proposed to be retained. Curre nt permitting thresholds are fo r any regulated air pollutant: CO, NO x , SO x(measured as SO 2 ), ozone, VOC, particulates, ai r contaminant subject to New Source Performance Standard (NSPS)), and HAPs. Current permitting thresholds are: VOC-0.5 tons per year (tpy); CO-1.0 tpy; NO 2 or NO x -1.0 tpy; SO 2 -1.0 tpy; lead (Pb)-0.3tpy; PM 10 -0.5 tpy.

 Definitions are proposed to be added to Rule 100. “Minor NSR modification” is a new term and is similar to ADEQ’s definition of “permitting exemption threshold”. “Permitting thre shold” is a new termbut includes the curre nt permitting thresholds. “Public notice threshold” is a new term; thresholds are lower than significance levels. “Regulated minor NSR pollutant” and “Regulated NSR pollutant” are new te rms and are similar to ADEQ’s terms/definitions. - Retention of Best Available Control Te chnology (BACT) and Reasonabl y Available Control Technology (RACT) control technology requirements in Rule 241. - Requirement of an air quality impact assessment if there is re ason to believe emissi ons resulting from a new or modified sourc e undergoing Minor NSR might cause or contri bute to an exceedance of the NAAQS. - Retention of the current alternative forms of public participation for smaller minor sources and sm all modifications that will not require formal publication of a notice in a newspaper.

If the state has not adopted a fee or tax for similar permits or approvals, the county may adopt a fee when authorized by law in the rule, ordinance or other regulation that does not exceed the re asonable costs of the county to issue and administer that permit or plan approval p rogram. Maricopa County fails to meet the National Ambient Air Quality Standards for both ozone and particulates. Wh ile currently class ified as a “marginal” ozone nonattainm ent area, the county recently fa iled to meet 2008 8-hour ozone standard by the marginal area attainment date and anticipates EPA will issue a notice proposing to re-classify the area to “moderate”. Further, a portion of the c ounty was classified as a serious oz one nonattainment area under the pr evious 1-hour ozone standard re quiring the county to continue to maintain the measures and requirements that allowed the county to attain that standard. Currently, a portion of Maricopa County and Apache Junction in Pinal County is de signated serious nonattainment for the PM 10 24-hour standard. This is the only serious PM 10 nonattainment area in Arizona . Maricopa County's permit rules for these programs are substantia lly identical to or impose no gr eater procedural burden than procedures for the review, issuance, revision and administration of permits i ssued by the State. However , Maricopa County's rules and proc edures contain requirements spec ific to nonattainment area stat us, increment consumption analys is and impacts on nearby nonattainment areas. These requirements resultin permit conditions that a ddress the source's proximity t o the PM 10 and ozone nonattainment areas and specific atmospheric, geogr aphical conditions found at the so urce's location, and control technology provisions require d by the CAA for nonattainment areas, and other control measures adopted into various nonattainment SIPs for Maricopa County. Specifically, va rious SIPs for Maricopa County have required the adoption of reasonably available control technology (RACT), best available contro l technology (BACT), and most stringent me asures (MSM) as required by CAA §§ 172, 182, 188, and 189. The department complies with A. R.S. § 49-112 in that the proposed amendments to 1) the department’s major source NSR rules are not more stringent than or in addition to a provision of Title 49 or rule adopted by th e director or any board or commission authorized to adopt rules pursuant to Title 49, 2) the department’s minor s ource rules address the peculiar local conditions in Maricopa C ounty and address long-standing federal requirements for nonattainments areas, and 3) the pr oposed amendments to the department’s NSR rules are authorized under A.R.S. Title 49, Chapter 3, Article 3 and consequentlyare not in lieu of a state program. 7.

The preliminary summary of the economic , small business, and consumer impact : The following discussion addresses each of the elements required for an economic, small business and cons umer impact statement (ESBCIS) as required by A.R.S. § 49-471.05 and prescribed in A.R.S. § 41-1055, subsections A, B and C. The department welcomes intere sted parties to provide additi onal relevant inform ation and documentation on the anticipated costs and benefits re sulting from the proposed rule revisions. An identification of the rulemaking. The rulemaking addressed by this ESBCIS is th e adoption of amendments designed to br ing the department’s New Source Review (NSR) rules into conformance with federal requirements for minor NSR and incorporate recent changes to EP A’s major NSR regulations. In particular, this ESBCIS covers amendments to th e following existing rules and appe ndices: Rules 100, 200, 210, 220, 230, 240, 241, 500, 510, 600, and Appendix D, E, and G. These rule change s are described in detail in Item 5 of this Notice of Propo sed Rulemaking. Two specific elements of the NSR amendments are addressed in the ESBCIS: 1. New and amended ambient standards that EPA has adopted since the depa rtment last amended Rule 510 and that may need to be addressed in New Source Re view (NSR) and Prevention of Significant (PSD) appl ications and permitting de cisions. Specifically: the more stringent annual and 24-hour National Ambient Air Quality Standards (NAAQS) for PM 2.5 , PM 2.5 increments, the more stringent eight-hour NAAQS for ozone, the new one-hour NAAQS for sulfurdioxide and nitrogen dioxide. These changes may result in increased compliance costs for sources and minor in creased administrative co sts for the department. 2. NSR reform amendments. These changes wi ll reduce compliance costs and will have a mixed effect on the department’s administrative costs. The remaining changes to major NSR are tec hnical in nature and should have little, if any, economic impact on the agency, businesses or consumers. An identification of the persons who will be directly affected by, bear the costs of or dire ctly benefit from the rulemaking

. In general terms, the persons who will be directly affected by and bear the costs of the propos ed rulemaking wi ll be businesses that construct or modify stationary sources thatare subject to major or minor NSR. The em issions thresholds fo r sources and modific ations subject to major and minor NSR are described in detail in Item 5 of this Notice of Proposed Rulemaking. The types of business operations subject to the department’s major NSR pr ogram typically include natural gas-fueled power plant s, petroleum products terminals, landfills, metal processing, and manufacturers of reinforced plastics, e xpandable foam, wood furn iture, steel products, and aircraft engine and part s. Major sources tend to be large fac ilities operated by publicly owned corporation s and employing hundreds or thousands of employees. As discussed in Item 5 of this Notice of Proposed Rulemaking, ma jor sources are potentially subjec t to minor as well as major N SR. Minor NSR may also apply to smal ler business operations or operations that, although substantial inscale, tend to have emissio ns below the major source thresholds. These include rock quarrying and crushing operatio ns, concrete batch pl ants, asphalt plants, semiconductor manufacturers, ch emical manufacturers, cr ematories, dry cleaners, landfills, wood product ma nufacturers, commercial printers and publicly owned wast e water treatmentfacilities. The above list is not exhaustive. Any busin ess that engages in pollutant emitting acti vities is potentially subject to NSR. Typ ical pollutant-emitting activi ties include fuel combustion to produce energy or as part of a process, the use of solvents, the applicat ion of surface coatings (such as paints and varnishes), the storage of fuels and other or ganic liquids and the handling of materials like ly to give rise to airborne dust. Tailpipe emis sions from mobile sources are not consid ered in determining NSR applicability. A cost benefit analysis of the following: (a) The probable costs and be nefits to the implementing agenc y and other agencies di rectly affected by the implementation and enforcement of the rulemaking. As required by A.R.S. § 49-480(D), the hourly rate for billablepermit actions under Rule 280 (Fees) Se ctions 301.1 and 302.1 has been set to reflect the department’s cost of processing pe rmit applications (14 A.A.R. 1767, May 9, 2008). Therefore, in assessing the costs to the department of conducting the permitting and administrative activities requi red by this rule, the dep artment has assumed that the cost per a dditional hour of employee tim e is equal to the current hourly rate of $150.00. Major NSR The department’s costs of implementing the additional major NSR requirements will likely be minimal. In fact implementation of NSR reform may result in a ne t cost savings for the department.July 31, 2015 | Published by the Arizona Secretary of State | Vol. 21, Issue 31

### County Notices According to A.R.S. § 49-112
One element of the major NSR amendments that will increase the department’s costs ofadministering the air quality permit program is the incorporation of the new ambient standards: the PM 2.5 NAAQS and PM 2.5 increments, the one-hour sulfur dioxide NAAQS and the one-hour nitrogen dioxide N AAQS. The air quality impact analysis for major NSR permit applications addressing these pollutants will be somewhatlonger and more complex than under currentrules and will therefore require additional review time by the department’s permit engineers. The ozone and lead NAAQS amendments, on the other hand, constitute an increase in the stringency of existing standards and should not result in any mo deling or review timebeyond that already required. The department has rece ived and processed three major NS R applications in the past ei ght years. Mostmajor NSR permit applications will require anair quality analysis for the ne w ambient standards. The departme nt’s Permit Engineering Division estimates that the additional review time will range from five to ten hours. The total annual cost to the agency per year for the additional major NSR requi rements will therefore range from $750.00 to $1,500.00 ($150.00 X 5 hours; $150.00 × 10 hours). Under Rule 280 (Fee s), Section 301.1, the permit appl icant will ultimat ely be required to reimbur se the department for this cost as part of its permit fee. The impact of NSR reform on the department’s air quality permitting costs is difficult to gauge. NSR reform includes elements that could either increase or reduce the costs of administering the major NSR program . The department belie ves that on balance, the cost savings of NSR reform will outweig h whatever additional costs wi ll be imposed. This is cons istent with EPA’s conclusion that NSR reform would allow state perm itting authorities to “focus their limited resources on those activities that could cause real and significant increases in pollution.” 67 Fed. Reg. 80186, 80192 (2002). Minor NSR The department’s Minor NSR as proposed w ould apply to all new sources with the potential to emit any regulated minor NSR pollutant in an amount equal to or greate r than the permitting threshold defined in Rule 100 and not subjec t to major source requirements under Rule 240 and any existing permitted source that increases its potential to emit any regulatedminor NSR pollutant in an amount equal to or greater than the minor NSR modification threshold (defined in Rule 100). As discussed in Item 5 of this Notice of Proposed Rulemaking, the proposed amendments to change from dail y to annual permitting threshold limits will enable less burdensome and streamlined record keepi ng requirements. The cha nge to annual threshold limits from per day limits reduces the record keeping burden, particularly for sm all sources, who would be more likely than larger sources to have emissions that fallnear the thresholds limits and would be required to maintain documentation of emissions levels. Based on experience in administering the ex isting permit program, the de partment’s Permit Engineer ing Division estimates that it will process approximately 100 applicati ons for permits or permit re visions subject to minor NS R per year. The Permit Engineering Division also estimate s that on average the additional time for proces sing the minor NSR compone nts (applicability and air quality impact anal yses) of a permit or permit revisi on application will be 2 hours per application for SCREEN modeling for ambient air quality assessment and 5 hours pe r application for reviewing refined modeling performed by the source. The Permit Engineering Division further estimates thatthe department will perfo rm SCREEN modeling for the air quality impact assessment on approximately 95% of the permit applications and will review the refined modeling perfo rmed by the source on approximately 5% of the permit applic ations. Therefore, the de partment estimates the additional annual cost to the department for the minor NSR components of a permit or pe rmit revision will be approximately $33,750.00 (95 app lications × 2 hours × $150.00 per hour = $28,500.00) + (5 applications × 7 hours × $150.00 per hour = $5,250.00). Additional Cost to the Depa rtment for NSR Amendments: The estimated additiona l annual cost to the department for the NSR amendments is a pproximately $35,000.00: $750.00 to $1,500.00 for additional major NSR costs + $33,750.00 for minor NSR costs = $34,500.00 to $35,250.00 Under Rule 280 (Fees), Sections 301.1 and 302.1, the permit applic ant will ultimately be required to reimburse the department for this cost as partof its permit fee. Other Agencies Eighty-seven sources operated by state agenci es require permits und er the current program. They represent approximately 2% of all department-permitted s ources. All of these state-operated sources will bear the same costs of compliance described in secti on (c) below for privately owned businesses. (b) The probable costs and be nefits to a political subdivision of this state directly affected by the implementation and enforcement of the rulemaking Four-hundred forty sources operated by politic al subdivisions require permits under th e current program. They represent approximately 10% of all departme nt-permitted sources. All of these sources will bear the same costs of compliance described in sec-

### County Notices According to A.R.S. § 49-112

1314 Vol. 21, Issue 31 | Published by the Arizona Secretary of State |July 31, 2015 tion (c) below for privately owned businesses. (c) The probable costs and benefits to busine sses directly affected by the rulemaking, including any anticipated effect on the revenues or payroll expendi tures of employers who are subject to the rulemaking. Major NSR As discussed in Item 5 of this Notice of Proposed Rulemaking, the amendments to the department’s major NSR rules are the minimum necessary to comply with federal requirements for the program. Even if the department failed to adopt these amendments, they would ultimately apply to major sources in Mari copa County either through the a doption of a federal implementation plan (FIP) by EPA under section 110(c) of the Clean Air Act (in the case of PSD) or the application of 40 CFR 51, Appendix S (in the case of nonattainment NS R). At best, a decision by the department not to adopt the major NSR amendments would result in a temporary delay in thei r application to sources in Maricopa County, Arizona. A discussion of the additional costs and benefits of the ame nded requirements at the county -level neverthe less follows. The new and amended ambient standards incor porated by this rule may result in the imp osition of three types of additional costs on applicants for major NSR permits. First, a new major source or major modifi cation with significant emissi ons of any of the pollutant s subject to a new ambient standard (the PM 2.5 increments and PM 2.5 NAAQS or the one-hour sulfur dioxide or nitrogen dioxide NAAQS) will be required to conduct additional modeling to demonstrat e compliance with these standards. The de partment estimates that one additional model run for each major NSR applications will be required. The Arizona Department of Envi ronmental Quality (ADEQ) estimated in their NSR Notice of Final Rulemaking (18 A.A.R. 1542, July 6, 2012) based on information received from an environmental consultant, that the cost of adding one model run to a refined model would be approximately $8,000.00. Second, applicants will be respons ible for paying permit fees equal to the add itional permit processing costs noted above due t o the major NSR amendments. As noted above , the estimated additional processing costs for major NSR will range from $750.00 to $1,500.00. Third, when modeling demonstrates an ambi ent impact resulting in non-compliance withan ambient standard (NAAQS or increments), mitigation beyond the level of control technology already required by major NS R is necessary. The cost of mitigation can be substantial but is highly dependent on the nature of the particular project and cannot be reliably estimated for purpose s of the ESBCIS. Moreover, because major NSR automatically requires a very stringent level of control (BACT or LAER), mitigation is rarely necessary. Miti gation necessary to address non-compliance with any of the new standards imposed in the majorNSR amendments will be an even rarer occurrence. Thus, the major NSR amendments are unlikely to result in additional mitigation costs. The total estimated annual costs to source s subject to major NSR as a result of the rule amendments willrange from $8,750.00 t o $9,500.00 ($8,000.00 + $750.00 to $1,500.00) plus the costs of mitigation, in the unlik ely event it is required. NSR reform, on the other hand, is likely to generate substantial savings for existing major source s that are potentially subjec t to major NSR. The revised method for determin ing baseline emissi ons and the actual-to- projected-actual alternative for determining the level of future emissions will make it easier for sources to demonstrate the inapplicability of major NSR. Sources that obtain PALs will essentially be able to avoid subsequent major NSR for a 10-year period. The savings from these reforms are difficult to estimate, but the department believes they will at least offset the additional costs described above. Minor NSR As noted above, the department estimates that approxi mately 100 minor and majo r sources requiring permits or permit revisions each year will be subject to minor NSR.The minor NSR amendments may result in the imposition of three types of additional costs on applicants for major NSR permits: First, ADEQ estimated base d on experience with contractors pe rforming accelerated permitting services that the cost of preparing the minor NSR components of a permit or permit revision application would average $4,000.00 (18 A.A.R. 1542, July 6, 2012). The department’s Permit Engineering Division agrees wi th that estimate and therefor e estimates annua l application preparation costs attributable to minor NSR at: 100 applications × $4,000.00 pe r application = $400,000.00. Second, applicants will be responsible fo r paying permit fees equal to the additional permit pr ocessing costs as noted above related to the minor NSR requirement for anair quality impact assessm ent. The departmentestimates above that SCREEN modeling may result in $300.00 of additiona l costs (2 hours × $150.00) and reviewing re fined modeling perform ed by the source may result in $1,050.00 of additi onal costs (7 hours × $150). Therefore, the department estimates annual additional permit pro-July 31, 2015 | Published by the Arizona Secretary of State | Vol. 21, Issue 31 

### 1315 

### County Notices According to A.R.S. § 49-112
cessing costs attributable to min or NSR at: 95 applications × $15 0 + 5 applications × $150 = $15,000. Third, based on estimat es provide by environmen tal consultants, ADEQ projected that th e cost of running a refined model to comply with minor NSR will be approximately $7,000 to $12,000 000 (18 A.A.R. 1542, Ju ly 6, 2012). The department’s Permit Engineering Division agrees with that estimate and estimated a bove that 5% of minor NSR applicants will need to perform refined modeling for the ambient air quality assessment. Therefore, the department estimates the a dditional annual cost attributable to performing a refined model by the source ranges between $35,000 and $60,000 (5 applic ations × $7,000 vs. 5 applications × $12,000). Lastly, the department anticipates no additional control costs will be incurred by sources as a result of minor NSR BACT or RACT requirements because BACT or RACT is required under the depa rtment’s current permitti ng program. The minor NSR amendments do have a new require ment for BACT or RACT for PM 2.5 and lead; however, most sources that emit PM 2.5 or lead also emit other pol lutants such as NO x , CO or PM 10 and these pollutants (NO x , CO or PM 10 ) will trigger the BACT or RACT analysis and generally the controls for these pollutants will also limit PM 2.5 and lead. Currently, the department does not have any lead sources that will trigger the requirement for a BACT or RACT determination for lead. Permits issued by the department are valid for five years; therefore, the department estimates annual minor NSR permit related costs for a source by dividing the total estima ted cost by five years. The department estimates the a nnual minor NSR costs for a source electing to have the department pe rform a SCREEN model at: $860.00. Whereas, the annual minor NSR cost s for a source electing to perform a refi ned model is estimate d to range between $2,410.00 and $3,410.00.

- Annual minor NSR costs for source electing to have MCAQD perform a SCREEN model: $860 = (($4,000 permit application + $300 permit processing costs)/5 yrs.) - Annual minor NSR costs for source el ecting to perform a refined model: $2,410 = (($4,000 permit application prep + $1,050 permit processing + $7,000 refined modeling cost)/5 yrs.) $3,410 = (($4,000 permit applic ation prep + $1,050 permit processing+ $12,000 refined modeling)/5 yrs.) A general description of the probable impact on private a nd public employment in businesses, agencies and political subdivisions of this state directly affected by the rulemaking. The department does not be lieve that the additional costs to businesses subjec t to the amended NSR requi rements, as described above, will be substantial enough to deter the construction or expansi on of business operati ons. Accordingly, there should be n o impact on private employment or on the employment of any political subdivisi ons subject to NSR. The department estimates that approximately one new full-time employee will be needed to implement the additional workload that will result from implementing minor NSR. A more precise estimate of the employment impact of minor NSR will be included in the ESBCIS for th e upcoming permit fee rule. The amendments to major NSR include elements that will both reduce (NSR reform) and increase (new ambient standards) agency workload. The department estimates that the net effect of the major NSR amendments on the agency’s employment needs will be zero. A statement of the probable impact of the rulemaking on small businesses. (a) An identification of the small bu sinesses subject to the rulemaking. Under A.R.S. § 49-101(20): “Small business” means a concern, including its affiliates, which is [1 ] independently owned and operated, which is [2] not dominant in its field and which [3] employs fewer than one hundred full-time employee s or which had gross annual receipts of less than four million dollars in its last fiscal year . (Emphasis added.) The department does not anticipate that this rulemaking will increase the nu mber of sources subject to the department’s NSR program. (b) The administrative and other costs required for compliance with the rulemaking. Small businesses will primarily incur the business costs described above for the minor NSR program. (c) A description of the methods thatthe agency may use to reduce the impact on small businesses. Establishing less costly compliance requireme nts in the rulemaking for small businesses.

### County Notices According to A.R.S. § 49-112

1316 Vol. 21, Issue 31 | Published by the Arizona Secretary of State |July 31, 2015 The department’s existing genera l permit program which falls under its minor NSR program is a less costly alternative currently available to many small businesses (e.g. dry cleaners, gas stations, surfac e coating operations, auto body shops, etc.). The general permits are designed specifically with small businesses in mind. General permitted source s will not incur the cost of an ambient air quality assessment as this would be done up front when the ge neral permit is establ ished rather than when an authorization to operate is issued. Many small busin esses currently required to obtai n permits are eligible for a general permit and are not required to ge t a non-title V permit. Thus, for some small businesse s, the general permit program is an existing and less costly alternative to the non-title V permit. (d) The probable cost and benefit to pr ivate persons and consumer s who are directly affected by the rulemaking. Some businesses may pass some of the a dditional costs estimated above on to cons umers. Because the amendments will not substantially increase existing air quality compliance costs, the department anticipates that the impact will be negligible. A statement of the probable effect on state revenues. Since the costs of the amendments will be recoverable through air quali ty permit fees, there will be no net effect on state revenues. A description of any less intrusive or less costly altern ative methods of achieving th e purpose of the rulemaking. As discussed above in It em 5 of this Notice of Proposed Rulemaking, the department has adopted am endments that the department believes to be th e minimum necessary to comply with federal NS R requirements.

. SECTION 200 - DEFINITIONS: To aid in the understanding of these rules, the following general definitions are provided. Additional definitions, as necessary, can be found in each rule of the Maricopa County Air Po llution Control Regulations. 200.1 AAC: Arizona Administrative Code. 200.2 ACT : The Clean Air Act of 1963 (P.L. 88-206; 42 Un ited States Code sections 7401 through 7671q ), as amended by the Clean Air Act Amendments of 1990 (P.L.101-549). through December 31, 2011 (and no future editions). 200.3 ACTUAL EMISSIONS: The actual rate of emissions of a regulated NSR pollutant from an emissions unit, as determined in Section 200.3(a) thr ough Section 200.3(e) of this rule:

a. In general, actual emissions as of a particular date shal l equal the average rate, in tons per year, at which the emissions unit actually emitted the pollutant during a 2-year consecutive 24-monthperiod that precedes the particular date and that is representative of normal source operation. The Control Of ficer may allow the use of a different time period upon a demonstration determinationthat it is more representativ e of normal source operation. Actual emissions shall be calculated using the emissions unit' s actual operating hours, production rates, and types of materials processed, stored, or combus ted during the selected time period. b. If there is inadequate inform ation to determine actual historical emissions, then theTheControl Officer may presume that source-specific allowa ble emissions for the emissions unit are equivalent to the actual emissions of the emissions unit.

c. For any emissions unit at a Title V source, other than an electric utility steam generatin g unit described in Section 200.3(e) of this rule that has not begun normal operations on the pa rticular date, actual emissions shall equal the unit’s potential to emit on that date. d. For any emissions unit at a Non-Title V source that has not begun normal operations on the particular date, actual emissions shall be based on applicable control equipm ent requirements and project ed conditions of operation.

e. For an electric utility steam generating unit (other than a new unit or the replacement of an existing unit), actual emissions of the unit, following the p hysical or operational change, shall equal the representative actual annual emissions of the unit, if the source owner and/or operator maintains and submits to the Control Officer on an annual basis, for a period of five years from the date the unit re sumes regular operation, inform ation demonstrating that the physical or operational change did not result in an emissi ons increase. A longer period, not to exceed 10 years, may be required by the Control Officer, if th e Control Officer determines the longer period to be more representative of normal source post-change operations. This definition shall not apply fo r calculating whether a significant emissions increase has occurred, or for establishing a PAL. Instead, proj ected actual emissi ons and baseline actual emissions in Rule 240 of thes e rules shall apply for those purposes. 200.4 ADMINISTRATOR: The Administrator of the United Stat es Environmental Protection Agency. 200.5 ADVISORY COUNCIL: The Maricopa County Air Pollution Control Ad visory Council appointed by the Maricopa County Board of Supervisors. 200.6 AFFECTED FACILITY: With reference to a stationary source, any apparatus to which a standard is applicable. 200.7 AFFECTED SOURCE: A source that includes one or more emissions units which are subject to emission reduction requirements or limitations under Title IV-Acid Deposition Control of the Act. 200.8 AFFECTED STATE: Any State whose air quality may be affected and th at is contiguous to Arizona or that is within 50 miles of the permitted source. 200.9 AIR CONTAMINANT: Includes smoke, vapors, charred paper, dust, soot, grime, carbon, fumes, gases, sulfuric acid mist aerosols, aerosol droplets, odors, particulate matter, wind borne matter, radioactive materials, noxious chemicals, or any other material in the outdoor atmosphere. 200.10 AIR POLLUTION: The presence in the outdoor atmosp here of one or more air contamin ants, or combinations thereof,

The offset may be obtained by re ductions in emissions from the source or modification, or from any other source within the allowa ble offset area. Credit for an emissions of fset can be used only if it has not been relied upon in demonstrating attainment or in demonstrating reasonable further progress (RFP), and if it has not been relied upon previously in issuing a permit or permit revision under this rule, under Section 301 through Section 305 of this rule, or not otherwise required under this rule or under any provision of the State Implementation Plan (SIP). 306.2 An offset shall not be sufficient unless reductions of total emissions for the particular pollutant for which the offset is required will be:

a. Obtained from sources within the allowable offset area; b. A surplus emission, which is an emission reduction not required by current regulations in the State Implementation Plan (SIP); not already relied upon for SIP planning purposes; and not used by the source to meet any other regulatory requiremen t, including, at the time emission reduction credits (ERCs) are used, reasonably available control technolo gy (RACT), reasonable further progress (RFP), or milestones thereof, or demonstration of attainment;

c. Contemporaneous with the operation, the new major source, or major modification; d. An emission enforceable by the Administrator;

Sufficient to satisfy the Control Of ficer that emissions from the new ma jor source or major modification, together with the offset, will result in reasonable further progress (RFP) for that pollutant. 306.3 In ozone nonattainment areas classified as marginal, total emissions of VOC and oxides of nitrogen from other sources shall offset those proposed or permitted fr om the major source or major modification by a ratio of at least 1.10:1. In ozone nonattainment areas classified as moderate, total emissions of VOC and oxides of nitrogen from other sources shall offset those proposed or permitted from the major source or major modification by a ratio of at least 1.15:1. New major sources and major modifications in serious and severe ozone nonattainment areas shall comp ly with this section and with Section 307 of this rule. 306.4 Only intrapollutant emission offsets shall be allo wed. Intrapollutant emission offset s for VOCs shall only include offset reductions in emissions of VOCs. Intrapollu tant emission offsets for oxides of nitrogen shall only include offset reductions in emissions of ox ides of nitrogen. 306.5 For purpose of this rule, reasonable further progress (RFP) sh all mean compliance with the schedule of annual incremental reductions in emissions of the applicable air pollutant pres cribed by the Control Officer based on air quality modeling under Section 510 of this rule, to providefor attainment of the applicable air quality standards by the deadlines set under Part D of Title I of the Act, or in an applicable implementation plan. 306.6 For the purpose of this rule, net air qual ity benefit shall mean that during similar time periods either Section 306.6(a) or Section 306.6(b) of thisrule is applicable:

j = The concentration level of the violation at the j th receptor from the pollutant before offsets.
K = The number of violations for the pollutant before offsets. b. The average of the ambient co ncentrations within the allowable offset area afte r the implementation of the contemplated offsets will be less than the average of th e ambient concentrations with in the allowable offset area without the offsets. 306.7 For the purpose of this rule, baseline shall be defined as:

a. The baseline of total emissions from any sources in existence or sources that have obtained a permit or permit revision under this rule, rega rdless of whether or not the sources are in actual operation at the time of application for the permit or permit revision, shall be the total ac tual emissions at the time the application is filed.

If the emission limitations for a particular pollutant al low greater emissions than th e potential emission rate of the source for that pollutant, the baselin e shall be the potential emission rate at the time application for the permit or permit revision under this rule is filed, and emission s offset credit shall be allowe d only for control below the potential emission rate. 306.8 For an existing fuel combustion source, offset credit shall be based on the allowable emissions under the regulations or permit conditions applicable to the sour ce for the type of fuel being burned at the time the application for the permit or permit revision under this rule is filed. If an existing source commits to switch to a cleaner fuel at some future date, emissions offset credit based on the actual emissions for the fuels involved shal l not be acceptable unless:

a. The permit or permit revision under this rule for the source specifically requires the us e of a specified alternative control measure that would achieve the same degree of emissions reduction if the source switches back to a dirtier fuel at some later date; and b. The source demonstrates to the satisfac tion of the Control Officer that it has secured an ad equate long-term supply of the cleaner fuel. 306.9 Offsets shall be made on either a pounds-per-hour, pounds-p er-day, pounds-per-quarter, tons-per-quarter, or tons-peryear basis, whichever is applicable, when all sources involved in the emission offs et calculations are operating at their maximum expected or allowed production rate and, except as otherwise provided in Section 306.8 of this rule, utilizing the type of fuel burned at the time the application for the permit or permit re vision under this rule isfiled. A tons-per-year basis shall not be used if the new or modi fied source or the source offsets are not expected to operate throughout the entire year. No emissions credit may be allowed for repl acing one VOC with another VOC of lesser reactivity. 306.10 Emissions reductions achieved by shutting down an existing source or permanently curtailing production or operating hours below baseline levels may be credited, if the work force to be affected has been notified of the proposed shutdown or curtailment. No offset credits for shutdowns or curtailments shall be provi ded for emissions reductions that are necessary to bring a source into compli ance with reasonably available control technology (RACT) or any other standard under an applicable implementation plan. 306.11 The allowable offset area shall be th e geographical area in which the sources are located whose emissions are being sought to offset emissions from a new major source or major modification . For the pollutants sulfur dioxide, PM 10 , and carbon monoxide, the allowable offset area shall be determined by atmospheric dispersion modeling. If the emission offsets are obtained from a source on the same premises or in the immediate vicinity of the new major source or major modification, and the pollutants disperse from substantially the same effectiv e stack height, atmospheric dispersion modeling shall not be required. The allowa ble offset area for all other pollutants shall be the nonattainment areas for those pollutants within which the new major sourceor major modification is to be located. 306.12 An emission reduction may only be used to offset emissions if the reduced level of emissions will continue for the life of the new source or modification and if the reduce d level of emissions is legally and federally enforceable at the time of permit issuance. It shall be considered legally enfo rceable, if the follow ing conditions are met:

a. The emission reduction is included as a condition in the permit of the source relied upon to offset the emissions from the new major source or major modi fication, or in the case of reductions from sources controlled by the applicant, is included as a condition of the permit or permit revision under this rule for the new major source or major modification; b. The emission reduction is adopted as a part of this rule or comparable rules of any other governmental entity or is contractually enforceable by the Control Officer and is in effect at the time the permit is issued. 306.13 For the purpose of this rule, the Contro l Officer may initiate or a source may propose a mobile source emission reduction

Unless otherwise provided in this rule, all requirements of Rule 200- Permit Requirements, Rule 210-Title V Permit Provisions, Rule 240-Permits For New Major Sources And Major Modifications To Existing Major Sources, Rule 245-Continuous Source Emission Monitoring, and Rule 270-Performance Tests of these rules apply. 307.2 Significant means, for the purposes of a major modification of any major source of VOC or oxides of nitrogen or for determining whether an otherwise minor source is major under Section 210-Definition Of Major Source of this rule, any physical change or change in the method of operations that results in net increases in emissions of either pollutant by more than 25 tons when aggregated with all other creditable increases and decrease s in emissions from the source over the previous five consecutive calendar years, including the calendar year in which the increase is proposed. For the purpose of Section 307 of this rule, a physical changeor change in the method of operation that results in an increase of less than one ton per year of VOC or oxides of nitrogen before netting does not trigger a 5-year aggregation exercise. 307.3 For any major source that emits or has the potential to emit less than 100 tons VOC or oxides of nitrogen per year, a significant increase in VOC or oxides of nitrogen, respectively, shall constitute a major modification, except that the increase in emissions from any discrete emissions unit, operation, or other pollutant emitting activity that is offset from other units, operations, or activities at the source at a rati o of 1.3:1 for the increase in VOC or oxides of nitrogen, respectively, from the unit, oper ation, or activity shall not be considered pa rt of the major modification. Best available control technology (BACT) shall be subs tituted for lowest achievable emission rate (LAER) for all major modifications under this section. Net emissions increasesin VOC or oxides of nitrogen above the in ternal offset described herein shall be subject to the offset requirements in Sec tion 307.5 and Section 307.6 of this rule. 307.4 For any stationary source that emits or has the potential to emit 100 tons or more of VOC or oxides of nitrogen per year, any significant increase in VOC or oxides of nitrogen, respectiv ely, shall constitute a major modification. If the increase in emissions from the modification at any discrete emissions unit, operation, or ot her pollutant emitting activity is offset from other units, operations or activities at the source at a ratio of 1.3:1 for the increase in VOC or oxides of nitrogen, respectively from the unit, opera tion or activity, best available control technology (BACT) shall be substituted for lowest achievable emission rate (LAER) at the unit, operation, or activity. Net emission s increases in VOC or oxides of nitrogen above the internal offset described herein shall be subject to the offset requirements in Section 307.5 and Section 307.6 of this rule. 307.5 For any new major source or major modification that is classified major because of emissions or potential to emit VOC or oxides of nitrogen in an ozone nonattainment area classified as serious, the increase in emi ssions of these pollutants from the source or modificatio n shall be offset at a ratio of 1.2:1. The offset shall be made in accordance with the provisions of Section 306 of this rule. 307.6 For any new major source or major modification that is classified as such because of emissions or potential to emit VOC or oxides of nitrogen in an ozone nonattainment area classified as severe, the increase in emissions of these pollutants from the source or modification shall be offset at a ratio of 1.3:1. If the State Implementation Plan (SIP) requires all existing major sources of these po llutants in the nonattainment area to apply be st available control technology (BACT), then the offset ratio shall be 1.2:1.

a. A new major source shall apply best av ailable control technology (BACT) fo r each pollutant listed in Rule 100- General Provisions And Definitions of these rules for which the potential to emit is significant. b. A major modification shall apply best available contro l technology (BACT) for each pollutant listed in Rule 100-General Provisions And Definitions of these rules for which the modification woul d result in a significant net emissions increase at the source. This requirement applies to each proposed emi ssions unit at which a net emissions increase in the pollut ant would occur as a result of a physical change or of a change in the method of operation in the unit.

c. For phased construction projects, the determination of best available control technology (BACT) shall be reviewed and modified as appropriate at the latest reason able time which occurs no la ter than 18 months prior to commencement of construction of each independent phase of the project. At such time , the owner or operator of the applicable stationary source may be required to demonstrate the adequacy of any previous determination of best available control techno logy (BACT) for the source. d. Best available control technology (BACT) shall be de termined on a case-by-cas e basis and may constitute application of production processes or available methods, systems, and te chniques, including fuel cleaning or treatment, clean fuels, or innovative fuel combustion tec hniques, for control of such po llutant. In no event shall such application of best available co ntrol technology (BACT) result in em issions of any pollutant which would exceed the emissions allowed by any applicable new source performance stan dard or national emission standard for hazardous air pollutants under Rule 360-New SourcePerformance Standards, Rule 370-Federal Hazardous Air Pollutant Program, and Rule 372-Maricopa County Hazardous Air Pollutants (HAPS) Program of these rules. If the Control Officer determines that tech nological or economic limita tions on the application of measurement methodology to a particular emissions unit would make the imposition of an emissions standard infeasible, a design, equipment, work practice, operational st andard or combination thereof may be prescribed instead to satisfy the requirement for the applicatio n of best available control technology (BACT). Such standard shall, to the degree possible, set forth the emissions reduction achievable by implementation of such design, equipment, work practice or operation, and shall provide for complia nce by means which achieve equivalent results.

e. The person applying for the permit or permit revision under this rule performs an air impact analysis and monitoring as specified in Section 50 0 of this rule and such analysis demonstrates that allowable emission increases from the proposed new major source or major modification, in conjunction with all other applicable emission increases or reductions, including secondary emissions, for all pollutants listed in Rule 500-Attainment Area Classification of these rule s, and minor and mobile sources for oxides of nitrogen: (1) Would not cause nor contribute to an increase in concentrations of any pollutant by an amount in excess of any applicable maximum allowable increa se over the baseline concentration in Rule 500- Attainment Area Classification of these rules for any attainment or unclassified area; or (2) Would not cause nor c ontribute to an increase in ambient con centrations for a pollutant by an amount in excess of the significance level for such pollutant in any adjacent area in which Arizona primary or secondary ambient air quality standards for that pollutant are being violated. A new major source of volatile organic compounds (VOCs) or oxides of nitrogen, or a major modi fication to a major source of VOCs or oxides of nitrogen, shall be presumed to contribute to violations of the Arizona ambient air quality standards for ozone if it will be located within 50 kilometers (31 miles) of a nonattainment area for ozone. The presumption may be rebutted for a new major source or major modification if it can be satisfactorily demonstrated to the Control Officer that emissi ons of VOCs or oxides of nitrogen from the new major source or ma jor modification will no t contribute to violations of the Arizona ambient air quality standards for ozone in ad jacent nonattainment areas for ozone. Such a demonstration shall include a showing that topographical, meteorological or other physical factors in the vicinity of the new major source or major modi fication are such that transport of VOCs emitted from the source are not expected to contribute to violations of th e ozone standards in the adjacent nonattainment areas.July 31, 2015 | Published by the Arizona Secretary of State | Vol. 21, Issue 31

"Excessive concentrations " means, for the purpose of determini ng good engineering prac tice stack height under Section 309.2(d) of this rule: (1) For sources seeking credit for stack height exceeding that established unde r Sections 309.2(b) and 309.2(c) of this rule, a maximum ground-level c oncentration due to emi ssions from a stack due in whole or in part to downwash, wakes, and eddy effects produced by nearby structures or nearby terrain features which individually is at leas t 40% in excess of the maximum concentration experienced in the absence of such downwash, wakes, or eddy effects and which contributes to a total concentration due to emissi ons from all sources that is greater than an ambient air quality standard. For sources subject to the requirements fo r permits or permit revi sions under this rule, an excessive concentration alte rnatively means a maximum gr ound-level concentration due to emissions from a stack due in whole or part to downwash, wakes or ed dy effects produced by nearby structures or nearby terrai n features which individually is at least 40% in excess of the maximum concentration e xperienced in the absence of such downwash, wakes or eddy effects and greater than the applicable maximum allowable increase contai ned in Rule 500-Attainment Area Classification of these rules. The allowable emis sion rate to be used in making demonstrations under Section 309.2(d) of this rule shall be pr escribed by the new source performance standard (NSPS) which is applicable to the source category, unl ess the owner or opera tor demonstrates that this emission rate is infeasible. Where such demonstrations are approved by the Control Officer, an alternative emission rate shall be established in consultation with the source owner or operator. (2) For sources seeking credit after October 11, 1983, for increases in existing stack heights up to the heights established under Sections 309.2( b) and 309.2(c) of this rule, either: (a) A maximum ground-level concentration due in wh ole or in part to downwash, wakes, or eddy effects as provided in Section 309.2(f)(1 ) of this rule, except that emission rate specified by any applicable State Implementation Plan (SIP) shall be used, or (b) The actual presence of a local nuisance caus ed by the existing stack, as determined by the Control Officer; and (3) For sources seeking credit after January 12, 1979 , for a stack height de termined under Sections 309.2(b) and 309.2(c) of this rule, where the C ontrol Officer requires th e use of a field study or fluid model to verify good engi neering practice (GEP) stack height, for sources seeking stack height credit after November 9, 1984, based on the aerodynamic in fluence of cooling towers, and for sources seeking stack height credit afte r December 31, 1970, based on the aerodynamic influence of structures not adequately represented by the equations in Sections 309.2(b) and 309.2(c) of this rule, a maximum ground-level concentration due in whole or in part to downwash, wakes, or eddy effects that is at least 40% in excess of the ma ximum concentration experienced in

c. The following definitions in 40 CFR 51 .301 are included: “Adverse impact on visibility”; “Natural conditions”; and “Visibility impairment”. 304.2 Emission calculation requirements to determine NSR applicability: Except for an applic ation for a PAL permit subject to Section 304.9, the provisions contained in 40 CFR 51.165(a)(2)(ii)(A) through (F) as incorporated by reference in Appendix G of these rules shall be used to determine if a proposed project will re sult in a new major stationary source or a major modification to an ex isting stationary source. These provisions shall not beused to determine the quantity of offsets required for a project subject the the require ments of Section 304.
304.3 Emission offsets: Increased emissions, ca lculated pursuant to Section 304.5(d), a major source or major modification subject to Section 304 shall be offset by reductions in the emissions of each po llutant for which the area has been designated as nonattainment and for which the source or modification is classi fied as major. Unless a ratio is provided for the applicable nonattainment ar ea in Section 304.6 of this rule, the ratio oftotal actual emissions reductions to emission increases shall be at least 1 to 1.
304.4 Baseline for determining credit for offsets: The baseline for determining creditfor emissions reductions shall be the actual emissions of the source fro m which offset credit is obtained.
304.5 Offset and emission reduction requirements:

a. All emission reductions claimed as offset credit shall meet the provisions contained in 40 CFR 51.165(a)(3)(ii)(A) through (D) as incorporated by re ference in Appendix G of these rules and 40 CFR 51.165(a)(3)(ii)(G) as incorporated by re ference in Appendix G of these rules. b. All emission reductions claimed as offset credits shall be federally enforceable by the time a permit is issued to the owner and/or operator of the major s ource subject to this Section and shall be in effect by the time the new or modified source subject to th e permit commences operations.

c. Location of offsetting emissions: The a pplicant of a major source or major m odification subject to this rule must obtain offset credits from the same source or from other sources in the same nonattainm ent area, except that the Control Officer may allow the applicant to obtain offset credits from another nonattainment area if the provisions contained in 40 CFR Part 51 Appendix S (IV)(D) as incor porated by reference in Appendix G of these rules are satisfied. d. The total tonnage of increased emissions , in tons per year, resulting from a ma jor modification thatmust be offset under this Section shall be determined by summing the difference betw een the allowable emissions after the modification and the actual emissions before the modification for each emissions unit.

e. Interpollutant offsetting: (1) For the purposes of satisfying the o ffset requirements the Control Office r may approve interpollutant emission offsets for precursor pollutants on a case by case basis, except for PM 10 , which is subject to Section 304.5(e)(2), and PM 2.5 , which is subject to Secti on 304.5(e)(5). In such cases, the Control Officer shall impose, based on an air quality analys is, emission offset ratios in additi on to the requirements of Sections 304.3 and 304.6.

RACT for a particular facility is de termined on a case-by-case basis, considering the te chnological feasibility and cost-effectiveness of the appl ication of the control techno logy to the source category. b. A control technique guideline issued by the Ad ministrator under secti on 108(f)(1) of the Act.

c. An emissions standard establ ished or revised by the Administrator for th e same type of sour ce under section 111 or 112 of the Act after November 15, 1990.
308 NAAQS COMPLIANCE ASSESSMENT: An ambient air quality assessment must demonstrate that emissions from the source or minor NSR modification will not interfere with attainme nt or maintenance of a standardimposed in the national ambient air quality standards. 308.1 An owner and/or operator of a source may elect to have the Control Officer pe rform a screen model of its emissions. If the results of the screen model indicatethat the source or minor NSR modification will interfere with attainment or maintenance of a standard imposed in the national ambient air qua lity standards, the owner and/or operator may perform a more refined model to make th e demonstration requi red by this rule. 308.2 The requirements of this rule shall be satisfied, if the results of the sc reen or more refined modeling conducted pursuant to Section 308.1 of this rule de monstrate either of the following:

a. Ambient concentrations resulting from emissions from the source or modification combined with existing concentrations of regulated minor NS R pollutants will not cause or exacer bate the violation of a standard imposed in nationl ambient air quality standards.
