# I. Executive Summary

This Technical Support Document (TSD) reviews revisions to the Oklahoma State Implementation Plan (SIP) for major New Source Review (NSR) permitting under the Clean Air Act. This review will determine if the revisions to the Oklahoma SIP are consistent wit h the requirements of the CAA and EPA’s regulations, policy and guidance.



## A. What actions are evaluated in this Technical Support Document? EPA’s most recent approval of revisions to the Oklahoma SIP for major NSR permitting requirements at Oklahoma Admi nistrative Code (OAC), Title 252, Chapter 100, Subchapter 8 (OAC 252:100

(b) Major modification (cont.) 2) Calculating significant emissions increase and significant net emissions increase before beginning actual construction. The procedure for calculating whether a significant emissions increase will occur depends upon the type of emissions units being modifie d, according to OAC 252:100

- 8

- 30(b)(3) through (5). This is the first step in determining if a proposed modification would be considered a major modification. The procedure for calculating whether a significant net emissions increase will occur at the majo r stationary source is contained in the definition of “net emissions increase”. This is the second step in the process of determining if a proposed modification is a major modification. Both steps occur prior to the beginning of actual construction. Regard less of any such preconstruction projections, a major modification results if the project causes a significant emissions increase and a significant net emissions increase.

“ Baseline actual emissions” means the rate of emissions, in TPY, of a regulated NSR pollutant, as determined in accordance with paragraphs (A) through (E) of this definition. A. The baseline actual emissions shall be based on current emissions data and the unit’s utilization during the period chosen. Current emissi ons data means the most current and accurate emission factors available and could include emissions used in the source’s latest permit or permit application, the most recent CEM data, stack test data, manufacturer’s data, mass balance, engineering calculat ions, and other emission factors. B. For any existing electric utility steam generating unit (E USGU), baseline actual emissions means the average rate, in TPY, at which the unit actually emitted the pollutant during any consecutive 24

- month period selected by the owner or operator within the 5

ups, shutdowns, and malfunctions. ii. The average rate shall be adjusted downward to exclude any noncompliant emissions that occurred while the source was operating above an emission limitation that was legally enforceable during the consecutive 24

- month period. iii. For a regulated NSR pollutant, when a project involves multiple emissions uni ts, only one consecutive 24

- month period shall be used to determine the baseline actual emissions for all the emissions units affected by the project. A different consecutive 24

The provision at “Regulated NSR Pollutant” subparagraph (B)(ii) states that a regulated NSR pollutant does not include any pollutant regulated under section 112(r) of the Act unless such pollutant is otherwise regulated under the Act

. Section 112(r) of the Act pertains to Prevention of Accidental Releases of the substances listed pursuant to paragraph (3) of section 112(r). This exemption is not provided for explicitly in the federal PSD provisions . However, because this provision applies only until such pollutant is not already regulated this provision is approvable. For example, section 112(r) of the Act lists sulfur dioxide as a listed substance which would be exempt ed from the definition of regulated NSR pollutant. But, because SO2 is regulated under the Act for PSD purposes, it is not exempted from the definition of Regulated NSR pollutant in the Oklahoma PSD
program.

i. How do the revisions to the Oklahoma PSD Program address the PSD program requirements of the NSR Reform Rule?

EPA promulgated its NSR Reform Program rules on December 31, 2002 (67 FR 80186). On November 7, 2003 (68 FR 63021), EPA promulgated a final action on its reconsideration of the December 31, 2002, NSR Reform Program rules . Our evaluation of the Oklahoma SIP submittals demonstrates the O D EQ has adopted and submitted revisions to the PSD permitting program that are sufficient to implement the required elements of NSR Reform. T he rule revisions effective June 15, 2006, submitted as a revision to the Oklahoma SIP on July 16, 2010, include rev isions to OAC 252:100 Part 7

– Prevention of Significant Deterioration (PSD) Requirements for Attainment Areas . T he submission covers Applicability, PSD requirements, Actuals PALs, and Definitions that implement the NSR Reform revisions . To be approvable u nder the SIP, states implementing Part C ( PSD permit program in 40 CFR 51.16 6 ) must include EPA’s December 31, 2002, changes as minimum program elements. The SIP revision submission is required to meet the following PSD SIP requirements to implement the NS R Reform rule and its applicability. The substantial revisions to the NSR Reform rules support these major aspects.

• Incorporation of a new method for determining baseline actual emissions defined in OAC 252:100

- Phase 2 and Certain Aspects of the 1990 Amendments Relating to NSR and PSD as They Apply to Carbon Monoxide (CO), PM and O3 NAAQS (O3 NAAQS Implementation Rule)?

The EPA finalized O 3 

### NAAQS Implementation Rule to provide additional regulatory requirements under the PSD SIP program regarding the implementation of the 8 hour ozone NAAQS. See

, 70 FR 71612 , November 29, 2005 . Regarding NSR, this rule is based on the proposed rule published on June 2, 2003 to implement the 8

- hour O 3 

### NAAQS. See

, 68 FR 32802. As well as the proposed rule published on July 23, 1996 for PSD and NNSR. See, 61 FR 38305.

• The Oklahoma PSD program contains a revised definition of “major stationary source” at OAC 252: 100

- 8

- 31 which specifies that a major source that is major for VOC or NOX is considered major for ozone.

• The Oklahoma PSD program contains a revised definition of “major modification” at OAC 252:100

- 8

- 31 which specifies that any significant increase or net emissions increase at a major stationary source that is significant for VOC or NOX shall be considered significant for ozone.

• The Oklahoma PSD program contains a revised definition of “significant” at OAC 252:100

- 8

- 31 which specif ies that the SER for ozon e is 40 TPY of VOC or NOX.

• The Oklahoma PSD program contains a revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 31 which specifies that VOC and NOX are precursors to ozone and thus regulated pollutants.

• The Oklahoma PSD program contains a r evised exemption from PSD monitoring at OAC 252:100

- 8

- 33(c)(1)(F) which specifies that no de minimis air quality level is provided for

ozone.

iii. How do the revisions to the Oklahoma PSD Program address the PSD program requirements of the EPA’s PSD and NN SR: Reasonable Possibilit y in Recordkeeping Rulemaking?

The EPA finalized PSD and NNSR: Possibility in Recordkeeping on December 21, 2007. See , 72 FR 72607. This rule clarifies the “reasonable possibility” recordkeeping and reporting standards of our 2002 NSR Reform rules. The “reasonable possibility” standard identifies for sources and reviewing authorities the criteria under which an owner or operator of a major stati onary source undergoing a physical change or change in the method of operation that does not trigger major NSR permitting requirements must keep records. The standard also specifies when the recordkeeping and reporting requirements apply to such sources.
The Oklahoma PSD program does not include the reasonable possibility provisions as promulgated by EPA at 40 CFR 51.166(r)(6)(vi). Instead, in the Oklahoma program, any source using the “ projected actual emissions” methodology is required to comply with the recordkeeping requirements at 40 CFR 51.166(r)(6)(i)

– (v). The Oklahoma Department of Environmental Quality submitted a letter of interpretation on February 8, 2016, that explained how the Oklahoma PSD program applies the recordkeeping and

### 225 reporting req uirements consistent with 40 CFR 51.166(r)(6)(i)

– (v) to all sources that use the “projected actual emissions” methodology; not just a subset of sources that have a “reasonable possibility” that would result in a significant emissions increase.
These requ irements apply to any source using the “projected actual emissions” methodology. Therefore, the Oklahoma SIP does not need to include the reasonable possibility provisions at 40 CFR 51.16 6 ( r )(6)(vi). This requirement for all sources to maintain records is more stringent than federal requirements and is therefore approvable.

iv. How do the revisions to the Oklahoma PSD program address PM 2.5 

### ?

The EPA promulgated two rules establishing both required and optional implementation regulations for NNSR permitting programs for PM 2.5 

### : the May 16, 2008 final rule for Implementation of the New Source Review (NSR) Program for Particulate Matter Less than 2.5 Micrometers (PM 2.5 

### ) (referred to as the NSR PM 2.5 

### Implementation Rule), 73 FR 28321; and the October 20, 2010 f inal rule for Prevention of Significant Deterioration (PSD) for Particulate Matter Less than 2.5 Micrometers (PM 2.5 

### )

– Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC) (referred to as the PM 2.5 

### PSD Increments

– SILs

– SMC Rule), 75 FR 64864.

a. How do the revisions to the Oklahoma PSD Program address the requi r ed elements of the NSR PM 2.5 

### Implementation Rule?

Following is a description of how the submitted revisions to the Oklahoma PSD program address the required elements of the NSR PM 2.5 

### Implementation Rule.

• Regulation of Direct PM 2.5 

### and Precursors: The revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 31 is consistent with the federal definition of “regulated NSR pollutant” at 40 CFR 51.16 6 ( b)(49) and identifies precursors to PM 2.5 

### in attainment areas. With respect to PM 2.5 

### , the revised definition of “regulated pollutant” at OAC 252:100

- 3 1 identifies su lfur dioxide and nitrogen oxides as regulated PM 2.5 

### precursors while volatile organic compounds (VOCs) are not regulated PM 2.5 

### precursors in PM 2.5 

### attainment areas in Oklahoma.

• E stablish SERs: The revisions to the PSD definition of “significant” at OAC 252:100

- 8

- 31 establishes significant emission rates for direct PM2.5 and for NOX and SO2 and PM2.5 precursors.

• Condensable PM 10 

### /PM 2.5 

### Emissions: The revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 3 1 is consistent with the federal requir ements promulgated on May 16, 2008 at 40 CFR 51.16 6 ( b)(49)(vi)

. Note that EPA subsequently promulgated a correction to the definition of “regulated NSR pollutant” with regard to the way in which condensable particulate matter is to be addressed with regard to emissions of PM at 40 CFR 51.166(b)(49)(i)( a ). The correction clarified that permit applicants are not required to consider the condensable portion of particulate matter in applicability determinations and in establishing emission limitations concernin g “PM emissions,” a term that represents a size range or indicator of particulate matter not considered to be a criteria pollutant. See 77 FR 65107, October 25, 2012. Although the O DEQ revisions do not

### 226 reflect this amendment of the federal condensable prov ision, the state’s revision to the PSD program to address condensable emissions is nonetheless approvable as it is more stringent than the current federal requirements for regulating condensibles as modified by EPA in the October 25, 2012 final rule.

b

. T he EPA’s Analysis of the Revisions to the Oklahoma PSD Permitting Program Submittal in light of the Litigation on the May 16, 2008 NSR PM 2.5 

### Implementation Rule

On January 4, 2013, the U.S. Court of Appeals for the District of Columbia Circuit, in Natural Resources Defense Council v. EPA 4 

### issued a decision that remanded the EPA’s 2007 and 2008 rules implementing the 1997 PM 2.5 

### NAAQS. With respect to the requirements for implementation of the PM 2.5 

### NAAQS in nonattainment areas, the Court found that EPA erred in implementing the PM 2.5 

### NAAQS in these rules solely pursuant to the general implementation provisions of subpart 1 of part D of title I of the CAA, rather than pursuant to the additional imple mentation provisions specific to particulate matter nonattainment areas in subpart 4. The Court ordered the EPA to “repromulgate ” these rules pursuant to subpart 4 consistent with this opinion.” Id. at 437. Subpart 4 of Part D, Title I of the CAA establish es additional provisions for particulate matter nonattainment areas.

The 2008 PM 2.5 

### NSR Implementation Rule addressed by the NRDC decision promulgated NSR requirements for implementation of PM 2.5 

### in both nonattainment areas (NNSR) and attainment/unclassifi able areas (PSD). 5 

### As the requirements of subpart 4 only pertain to nonattainment areas, the EPA does not consider the portions of the 2008 rule that address requirements for PM 2.5 

### in attainment and unclassifiable areas to be affected by the court’s opini on. Moreover, the EPA does not anticipate the need to revise any PSD requirements promulgated in the 2008 NSR PM 2.5 

### Implementation Rule in order to comply with the court’s decision. Accordingly, the EPA’s proposed approval of revisions to the Oklahoma SIP with respect to the PSD requirements promulgated by the 2008 NSR PM 2.5 

### Implementation Rule does not conflict with the court’s opinion.

- 33(c)(1)(C) in the Oklahoma PSD program. The EPA is severing these provisions from this TSD and will address these provisions in a separate action.

### 228 v. How do the revisions to the Oklahoma PSD program satisfy the PSD requirements of EPA’s GHG Tailoring Rule?

On June 3, 2010, the EPA published a f inal rule, known as the Tailoring Rule, which phased in permitting requirements for greenhouse gas (GHG) emissions from stationary sources under the CAA PSD and title V permitting programs (75 FR 31514). Under its interpretation of the CAA at the time, the EPA believed the Tailoring Rule was necessary to avoid a sudden and unmanageable increase in the number of sources that would be required to obtain PSD and title V permits under the CAA because the sources emitted or had the potential to emit GHGs above
t he applicable major source and major modification thresholds.
In Step 1 of the Tailoring Rule, which began on January 2, 2011, the EPA limited application of PSD and title V requirements to sources only if they were subject to PSD or title V ‘‘anyway’’ due to their emissions of non

- GHG pollutants. These sources are referred to as ‘‘anyway sources.’’ In Step 2 of the Tailoring Rule, which began on July 1, 2011, the EPA applied the PSD and title V permitting requirements under the CAA to sources that were cla ssified as major, and, thus, required to obtain a permit, based solely on their GHG emissions or potential to emit GHGs, and to modifications of otherwise major sources that required a PSD permit because they increased only GHG emissions above the level in the EPA regulations.
On June 23, 2014, the U.S. Supreme Court issued a decision in Utility Air Regulatory Group (UARG) v. EPA, 134 S. Ct. 2427, addressing the application of stationary source permitting requirements to GHGs. The U.S. Supreme Court held that the EPA may not treat GHGs as an air pollutant for the specific purpose of determining whether a source is a major source (or a modification thereof) and thus required to obtain a PSD or title V permit. With respect to PSD, the ruling effectively uph eld PSD permitting requirements for GHG emissions under Step 1 of the Tailoring Rule for ‘‘anyway sources,’’ and invalidated PSD permitting requirements for Step 2 sources. Because the Supreme Court decision affirmed in part and reversed in part an earlier decision of the D.C. Circuit in Coalition for Responsible Regulation v. EPA, 684 F.3d 102 (D.C. Cir. 2012), on April 10, 2015, the D.C. Circuit issued an Amended Judgment (Nos. 09

– 1322, 10

– 073, 10

– 1092 and 10

– 1167), which reflects the UARG v. EPA Supreme Court decision. The D.C. Circuit simultaneously issued its mandate, which means that the Coalition Amended Judgment became final and effective upon issuance. In the Coalition Amended Judgment, the D.C. Circuit ordered that the EPA regulations under review (including 40 CFR 51.166(b)(48)(v) and 40 CFR 52.21(b)(49)(v)) be vacated to the extent they require a stationary source to obtain a PSD permit if GHGs are the only pollutant (i) that the source emits or has the potential to emit above the applicable major source thresholds, or (ii) for which there is a significant emissions increase from a modification. The D.C. Circuit also ordered that the regulations under review be vacated to the extent they require (i) a stationary source to obtain a title V permit so lely because the source emits or has the potential to emit GHGs above the applicable major source thresholds and (ii) the EPA to consider further phasing in the GHG permitting requirements at lower GHG emission thresholds (in particular 40 CFR 52.22 and 40 CFR 70.12, 71.13). In response to the Coalition Amended Judgment, the EPA promulgated a good cause final rule on August 19, 2015, removing the PSD permitting revisions for Step 2, non

- anyway sources from the federal regulations at 40 CFR 51.166(b)(48)(v) and 52.21(b)(49)(v). The EPA no longer has the authority to regulate Step 2, non

- anyway sources, nor can we approve provisions in a

### 229 state regulation providing this authority. We anticipate taking future federal rulemakings to address the remainder of the UARG and Coalition judgments. We further anticipate that these federal actions will necessitate revisions to the existing PSD regulations in our SIP

states. ODEQ submitted revisions to the Oklahoma SIP addressing the regulation and permitting of GHGs on February 6, 2012 and January 18, 2013

. EPA finds that the provisions for step 1 permitting submitted on February 6, 2012, at OAC 252:100

- 8

- 31, definition of “subject to regulation,” subparagraphs (A), (B), (C), (D), and (F) are consistent with fede ral requirements for Step 1 GHG permitting at 40 CFR 51.166(b)(48)

. Additionally, the February 6, 2012, submittal also included revisions to the general definitions at OAC 252:100

- 1

- 3 to include new definitions for CO2e and GHG consistent with the federal PSD definitions at 40 CFR 51.166(b)(48)(ii)( a ) and 51.166(b)(48)(i), respectively.
Note that EPA is not acting on the subparagraph (E) of the “ subject to regulation ” definition submitted on February 6, 2012, because this subparagraph establishes the Step 2 permitting requirements. We are also not acting on the revisions submitted January 18, 2013 to revise the definitions of “ CO2e ” and “ subject to regulation ” to provide for the GHG Biomass Deferral. Both the Step 2 permitting and the GHG Biomass Deferral p rovisions are being addressed in a separate rulemaking proposing disapproval. EPA proposed these provisions for disapproval on January 11, 2016. See 81 FR 1141. EPA promulgated our final disapproval on May 23, 2016. See 81 FR 32239.

vi

. EPA’s Analysis of the Approvability of the Oklahoma PSD Automatic Rescission Provisions for GHGs

Oklahoma’s February 6, 2012, SIP submittal adds automatic rescission provisions to the State’s PSD regulations at OAC 252:8

- 100

- 36.2, definition of “subject to regulation

, ” sub paragraph (F). The automatic rescission provisions provide that in the event that federal legislation or a federal court determines that a portion of the EPA’s tailoring rule, endangerment finding, or light

- duty vehicle GHG standard is unenforceable, than that provision will be enforceable in the Oklahoma PSD program only to the extent that it is enforceable by the EPA.
In assessing the approvability of this severability provision, the EPA considers two key factors: (1) whether the public will be given reas onable notice of any change to the SIP that occurs as a result of the automatic rescission provisions, and (2) whether any future change to the SIP that occurs as a result of the automatic rescission provisions would be consistent with the EPA’s interpreta tion of the effect of the triggering action on federal GHG permitting requirements. See,
e.g., 79 FR 8130 (February 11, 2014) and 77 FR 12484 (March 1, 2012). These criteria are derived from the SIP revision procedures set forth in the CAA and federal regu lations.
Regarding public notice, CAA section 110(l) provides that any revision to a SIP submitted by a State to EPA for approval “shall be adopted by such State after reasonable notice and public hearing.” In accordance with CAA section 110(l), ODEQ follo wed applicable notice

- and

comment procedures prior to adopting the automatic rescission provisions. Thus, the public is on notice that the automatic rescission provisions in the Oklahoma PSD program will enable the

### 230 Oklahoma PSD program and the Oklahoma SIP to update automatically to reflect any order by a federal court or any change in federal law that limits or renders ineffective the regulation of GHGs under the CAA’s PSD permitting program. In a letter dated April 22, 2016 , the ODEQ has stated that it wo uld provide notice to the general public and regulated community of the changes to the Oklahoma PSD program in the event of any change in the federal permitting requirements for GHGs.
The EPA’s consideration of whether any SIP change resulting from Oklahom a’s automatic rescission provisions would be consistent with EPA’s interpretation of the effect of the triggering action on federal GHG permitting requirements is based on 40 CFR 51.105, which states that “[r]evisions of a plan, or any portion thereof, wil l not be considered part of an applicable plan until such revisions have been approved by the Administrator in accordance with this part.” To be consistent with 40 CFR 51.105, any automatic SIP change resulting from a court order or federal law change must be consistent with the EPA’s interpretation of the effect of such order or federal law change on GHG permitting requirements. We interpret this provision to mean that Oklahoma will wait for and follow the EPA’s interpretation as to the impact of any feder al law change or the D.C. Circuit or the U.S. Supreme Court issues an order before Oklahoma’s SIP would be changed. In the event of a court decision or federal law change that triggers (or likely triggers) application of Oklahoma’s automatic rescission pro visions, the EPA intends to promptly describe the impact of the court decision or federal law change on the enforceability of its GHG permitting regulations.

. How do the revisions to the Oklahoma PSD program address the Fugitive Emissions Rule and subsequent EPA

- stays?

On December 19, 2008, the EPA issued a final rule revising the requirements of PSD and NNSR program regarding the treatment of fugitive emissions (Fugitive Emissions Rule, 73 FR 77882)). The Fugitive Emissions Rule required fugitive emissions to be included in determining whether a physical or operational change results in a major modification only for sources in industries that have been designated through rulemaking under section 302(j) of the CAA. Previously, the EPA rules require d that fugitive emissions be included in major modification applicable determinations for all source categories.
On February 17, 2009, the Natural Resources Defense Council (NRDC) submitted a petition for reconsideration of the December 2008 Fugitive Emiss ions Rule. On April 24, 2009, the EPA responded to the petition by letter indicating we were convening a reconsideration proceeding for the December 2008 Fugitive Emissions Rule and granted a 3

- month administrative stay of the rule provisions. The initial 3

An interim final rule extending the administrative stay for an additional 3 months became effective on December 31, 2009. See 74 FR 5265692. An additional 18 month stay was finalized on March 31, 2010. See 75 FR 16012.

. This final action stayed indefinitely the provisions

### 231 of the December 2008 Fugitive Emissions Rule. Following is a summary of how the Oklahoma PSD program addresses fugitive emissions.

• The Oklahoma PSD program does not include the revisions to “major modif ication” or “net emissions increase” promulgated by EPA in the December 2008 Fugitive Emissions Rule at 40 CFR 51.16 6 ( b)(2)(v ) or 40 CFR 51. 166(b)(3)(iii ) ( d ) , respectively. As such, the Oklahoma PSD program does not include the provisions that are indefini tely stayed.

• The Oklahoma PSD program continues to require fugitive emissions to be included in the major modification applicability determina tions for all source categories:

o The Oklahoma SIP at OAC 252:100

- 1

- 3 includes the definition of “fugitive emissio ns” consistent with the federal definition at 40 CFR 51.166(b)(20).

o The definition of “projected actual emissions” at OAC 252:100

- 8

- 31 in the Oklahoma PSD program has been revised to include fugitive emissions to the extent quantifiable and emissions associated with startups, shutdowns, and malfunctions . This definition has also been revised to allow for the use of the emission unit’ s potential to emit in TPY consistent with 40 CFR 51.166(b)(40)(ii)(b) and (d).

o The definition of “baselin e actual emissions” at OAC 252:100

- 8

- 31 in the Oklahoma PSD program has been revised to include fugitive emissions to the extent quantifiable for any existing EUSGU and any existing emissions unit other than an EUSGU consistent with 40 CFR 51.166(b)(47)(i) (a) and (ii)(a). This definition has also been revised to address the requirements for calculating baseline actual emissions for a new emissions unit consistent with 40 CFR 51.166(b)(47)(iii). This definition has also been revised to address the requiremen ts for calculating baseline actual emissions or a PAL consistent with 40 CFR 51.166(b)(47)(iv).

o The Oklahoma SIP at OAC 252:100

- 8

- 33(a)(1)(B) includes the exemption at 40 CFR 51.166(i)(1)(ii).

o The source obligation provisions at OAC 252:100

- 8

- 36.2(c) for t he requirements when using projected actual emissions are consistent with th e obligation provisions found at 40 CFR 51.166(r)(6)(i)

– (v). Note that the Oklahoma PSD program does not include the reasonable possibility provisions at 40 CFR 51.16 6 ( r )(6)(vi). Rather, the Oklahoma PSD program requires all sources using the “projected actual emissions” methodology to maintain records consistent with 40 CFR 51.16 6 ( r )(6). This is more stringent than federal requirements and is therefore approvable.

o The Oklahoma PS D program incorporates by reference the PSD PALs provisions at 40 CFR 51.166(w) as of July 2, 2007. However, the definition of “baseline actual emissions” for PALs is not part of this incorporation by reference. Per OAC 252:100

- 8

- 31 definition of “baseline actual emissions

, ” paragraph (E) for a PAL stationary source, the baseline actual emissions for an EUSGU or other existing emissions units other than an EUSGU shall be calculated using the general Oklahoma PSD definition for “baseline actual emissions” a t OAC 252:100

- 8

- 31 and therefore will include fugitive emissions to the extent quantifiable.

OAC 252:100 Part 5 provides the requirements for Permits f or Part 70 Sources. Because a new major NNSR source or a major NNSR modification will also be an applicable requirement under Part 70 permitting, it is appropriate that the general provisions for Part 70

sources that also apply to the major NNSR program sh ould be part of the Oklahoma SIP . However, some provisions of the Part 70 source requirements are not applicable under title I

– those elements are identified elsewhere in this TSD.
It is also acceptable for the applicability of the NNSR program to clearl y state that PSD requirements may apply as well. This is consistent with Title I implementation under 51.165 and 51.166.

Sources and modifications that are major in s ize and proposed for construction in an area which has been designated as nonattainment for any applicable ambient air quality standard are subject to the requirements for the nonattainment area, if the source or modification is major for the nonattainment pollutant(s) of that area. b. In addition, the requirements of a PSD review (Part 7 of this Subchapter) would be applicable if any other regulated pollutant other than the nonattainment pollutant is emitted in significant amounts by that source or modificati on.

New provisions effective June 1, 2009; Submitted June 24, 2010.

a) Ozone. The requirements of Part 9 of OAC 252:100

– 8 applicable to major stationary sources and major modifications of VOCs shall apply to NO X emissions from major stationary sources and major modifications of NO X in an ozone transport region (as defined i n 42 U.S.C 7511c) or in any ozone nonattainment area, except in ozone nonattainment areas or in portions of an ozone transport region where the Administrator has granted a NO X waiver applying the standards set forth under section 182(f) of the Act and the waiver continues to apply. b) PM10 Precursors. The requirements of Part 9 OAC 252:100

– 8 applicable to major stationary sources and major modifications of PM10 shall also apply to major stationary sources and major modifications of PM10 precursors, except wh ere the Administrator determines that such sources do not contribute significantly to PM10 levels that exceed the PM10 ambient standards in the area. The new provision at OAC 252:100

- 8

- 54.1(a) identifies that NO X is an ozone precursor. This is consistent w ith the federal requirements at 40 CFR 51.165(a)(1)(xxxvii)(C)(1). This revision is approvable.

The new provision at OAC 252:100

- 8

- 54(b) identifies that requirements of NNSR applicable to major stationary sources and major modifications of PM10 shall also apply to major stationary sources and major modifications of PM10 precursors. This is consistent with the federal requirements at 40 CFR 51.165(a)(11), This revision is approvable.



### The new requirements for ozone and PM10 NNSR precursors are consistent with federal requirements. These requirements are approvable.

i. How do the revisions to the Oklahoma NNSR Program address the NNSR program requirements of the NSR Reform Rule ?

EPA promulgated its NSR Reform Program rules on December 31, 2002 (67 FR 80186). On November 7, 2003 (68 FR 63021), EPA promulgated a final action on its reconsideration of the December 31, 2002, NSR Reform. Our evaluation of the Oklahoma SIP submittals de monstrates the O DEQ has adopted and submitted revisions to the NNSR permitting program that are sufficient to implement the required elements of NSR Reform. T he rule revisions effective June 15, 2006, submitted as a revision to the Oklahoma SIP on July 16, 2010, include revisions to OAC 252:100 Part 9

– Major Sources Affecting Nonattainment Areas. T he submission covers Applicability, NNSR requirements, Actuals PALs, and Definitions that support the NSR Reform program. To be approvable under the SIP, states implementing Part D (NNSR permit program in 51.165) must include EPA’s December 31, 2002, changes as minimum program elements. The SIP revision submission is required to meet the following NNSR SIP requirements to implement the NSR Reform rule and its applicability. The substantial revisions to the NSR Reform rules support these major aspects.

• Incorporation of a new method for determining baseline actual emissions defined in OAC 252:100

- 8

- 5 0 and OAC 252:100

- 8

- 5 1 ;

• Incorporation of the actual

- actual methodology for determining whether a major modification has occurred found in OAC 252:100

- 8

- 50 ; and

• Inclusion of rules that allow major stationary sources to comply with Plantwide Applicability Limits (PALs) to avoid having a significant emissi ons increase that triggers the requirements of the major NSR program found OAC 252:100

- 8

- 56

.

### 273 ii. How do the revisions to the Oklahoma NNSR Program satisfy the NNSR requirements in EPA’s November 29, 2005, Final Rule to Implement the 8

- hour Ozone (O3) NA AQS

- Phase 2 and Certain Aspects of the 1990 Amendments Relating to NSR and PSD as They Apply to Carbon Monoxide (CO), PM and O3 NAAQS (O3 NAAQS Implementation Rule)?

The EPA finalized O 3 

### NAAQS Implementation Rule to provide additional regulatory require ments under the PSD SIP program regarding the implementation of the 8 hour ozone NAAQS. See

, 70 FR 71612 . Regarding NSR, this rule is based on the proposed rule published on June 2, 2003 to implement the 8

- hour O 3 

### NAAQS. See

, 68 FR 32802. As well as the proposed rule published on July 23, 1996 for PSD and NNSR. See, 61 FR 38305. These changes provide a consistent national program for permitting major stationary sources under section 110(a)(2)(C) and parts C and D of title I, i ncluding major stationary sources of ozone precursors in ozone nonattainment areas. This rule codifies requirements added to part D of Title I of the CAA in the 1990 Amendments related to permitting of major stationary sources in areas that are nonattainme nt for O 3 

### , PM, and CO NAAQS. Second, EPA revised the criteria for crediting emissions reductions credits from shutdowns and curtailments as offsets. Third, revisions to the regulations for permitting of major stationary sources in nonattainment areas in in terim periods between designation of new nonattainment areas and EPA’s approval of a revised SIP. Fourth, EPA changed the regulations that impose a ban prohibiting construction of new or modified major stationary sources in nonattainment area where the Sta te fails to have an implementation plan meeting all of the requirements of part D. The revisions to the Oklahoma NNSR Program address the required elements of the EPA’s final 8

- hour Ozone NAAQS Phase 2 rule as follows:

• The Oklahoma NNSR program at OAC 252: 100

- 8

- 51 incorporates by reference the federal NNSR definition of “major stationary source” at 40 CFR 51.165(a)(1)(iv) as of July 1, 2010.

• The definition of “major modification” at OAC 252:100

- 8

- 51 was revised by adding a new paragraph (C) and new OAC 252 :100

- 8

- 54.1(a) together requires NOX to be regulated as an ozone precursor in an ozone nonattainment area consistent with the federal requirements at 40 CFR 51.165(a)(1)(v) and (a)(3)(8).

• The Oklahoma NNSR program at OAC 252:100

- 8

- 51 incorporates by refere nce the federal NNSR definition of “significant” at 40 CFR 51.165(a)(1)(x) as of July 1, 2010.

• New OAC 252:100

- 8

- 51.1(b) incorporates by reference the emission offset requirements in 40 CFR 51.165(a)(9) as of July 2, 2007.

• New OAC 252:100

- 8

- 54.1(b) makes t he PM10 requirements apply to the PM10
precursors consistent with the requirements at 40 CFR 51.165(a)(10)

iii. How do the revisions to the Oklahoma NNSR Program address the NNSR program requirements of the EPA’s PSD and NNSR: Reasonable Possibilit y in Re cordkeeping Rulemaking?

The EPA finalized PSD and NNSR: Possibility in Recordkeeping on December 21, 2007. See , 72 FR 72607. This rule clarifies the “reasonable possibility” recordkeeping and reporting standards of our 2002 NSR Reform rules. The “reasonable possibility” standard identifies for sources and reviewing authorities the criteria under which an owner or operator of a major stationary source

### 274 undergoing a physical change or change in the method of operation that does not trigger major NSR permitting requirements must keep records. The standard also specifies when the recordkeeping and reporting requirements apply to such sources. The revisions to the Oklahoma NNSR program effective June 15, 2006, submitted July 16, 2010, incorporate by refe rence of 2007 the requirements in 40 CFR 51.165(a)(6)(i) through (a) (6) (v). These requirements apply to
any source using the “projected actual emissions” methodology. Therefore, the Oklahoma SIP does not need to include the reasonable possibility provision s at 40 CFR 51.165 (a)(6)(vi).
The Oklahoma Depart ment of Enviro nmental Quality submitted a letter of interpretation on February 8, 2016, that explained how the Oklahoma PSD program applies the recordkeeping and reporting requirements consistent with 40 CFR 51.166(r)(6)(i)

– (v) to all sources that use the “projected actual emissions” methodology; not just a subset of sources that have a “reasonable possibility” that would result in a significant emissions increase. While the February 8, 2016, letter is s pecific to the Oklahoma PSD program and the requirements at OAC 252:100

- 8

- 36.2, we find that the Oklahoma NNSR program similarly and the same argument would apply. Any source using the “projected actual emissions” methodology is required to use the recordk eeping and reporting requirements consistent with 40 CFR 51.165(a)(6)(i)

– (v)

. The Oklahoma NNSR program is more stringent than federal requirements.

iv. How do the revisions to the Oklahoma NNSR program address the requirements of the May 16, 2008 NSR P M 2.5 

### Implementation Rule?

The EPA promulgated two rules establishing both required and optional implementation regulations for NNSR permitting programs for PM 2.5 

### : the May 16, 2008 final rule for Implementation of the New Source Review (NSR) Program for P articulate Matter Less than 2.5 Micrometers (PM 2.5 

### ) (referred to as the NSR PM 2.5 

### Implementation Rule), 73 FR 28321; and the October 20, 2010 final rule for Prevention of Significant Deterioration (PSD) for Particulate Matter Less than 2.5 Micrometers (PM 2 .5 

### )

– Increments, Significant Impact Levels (SILs) and Significant Monitoring Concentration (SMC) (referred to as the PM 2.5 

### PSD Increments

– SILs

– SMC Rule), 75 FR 64864. The State’s August 16, 2010 submittals address the regulatory requirements of these implementation rules for the 1997 and 2006 PM 2.5 

### NAAQS as applicable to its NNSR permitting program. Based on the analysis presented below and in our accompanying TSD, EPA is proposing to find that the August 16, 2010, revision to the Oklahoma NNSR permitting program includes all of the NNSR requirements of the 2008 final NSR PM 2.5 

### Implementation Rule for the following reasons:
(1) Regulation of Direct PM 2.5 

### and Precursors: The revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 51 is co nsistent with the federal definition of “regulated NSR pollutant” at 40 CFR 51.165(a)(1)(xxxvii) and identifies precursors to PM 2.5 

### in nonattainment areas. With respect to PM 2.5 

### , the revised definition of “regulated pollutant” at OAC 252:100

- 8

- 51 identifie s sulfur dioxide and nitrogen oxides as regulated PM 2.5 

### precursors while volatile organic compounds (VOCs) and ammonia are not regulated PM 2.5 

### precursors in PM 2.5 

### nonattainment areas in Oklahoma.
(2) Establish SERs: The February 6, 2012, submittal incorp orates by reference the definition of “ significant” at 40 CFR 51.165(a)(1) as it exists on July 1, 2011, and will therefore include

### 275 significant emission rates for direct PM 2.5 

### and for sulfur dioxide and nitrogen oxides as PM 2.5 

### precursors as promulgated by EPA at 40 CFR 51.165(a)(1)(xxxvii)(C) and (D) on May 16, 2008

. (3) Condensable PM 10 

### /PM 2.5 

### Emissions: The revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 51 is consistent with the federal requirements promulgated on May 16, 2008 at 40 CFR 51.165(a)(1)(xxxvii).

v. The EPA’s Analysis of the February 6, 2012

, SIP Revisions to the Oklahoma NNSR Permitting Program Submittal in light of the Litigation on the May 1 6, 2008 PM 2.5 

### NSR Implementation Rule

On January 4, 2013, the U.S. Court of Appeals for the District of Columbia Circuit, in Natural Resources Defense Council v. EPA 6 

### issued a decision that remanded the EPA’s 2007 and 2008 rules implementing the 1997 PM 2.5 

### NAAQS. With respect to the requirements for implementation of the PM 2.5 

### NAAQS in nonattainment areas, the Court found that EPA erred in implementing the PM 2.5 

### NAAQS in these rules solely pursuant to the general implementation provisions of subpart 1 of part D of title I of the CAA, rather than pursuant to the additional implementation provisions specific to particulate matter nonattainment areas in subpart 4. The Court ordered the EPA to “repromulgate ” these rules pursuant to subpart 4 consistent with t his opinion.” Id. at 437. Subpart 4 of Part D, Title I of the CAA establishes additional provisions for particulate matter nonattainment areas.

The 2008 PM 2.5 

### NSR Implementation Rule addressed by the NRDC decision promulgated NSR requirements for implemen tation of PM 2.5 

### in both nonattainment areas (NNSR) and attainment/unclassifiable areas (PSD). 7 

### As the requirements of subpart 4 only pertain to nonattainment areas, the EPA does not consider the portions of the 2008 rule that address requirements for PM 2. 5 

### in attainment and unclassifiable areas to be affected by the court’s opinion. Moreover, the EPA does not anticipate the need to revise any PSD requirements promulgated in the 2008 NSR PM 2.5 

### Implementation Rule in order to comply with the court’s decision

. With respect to the nonattainment area requirements in affected rules, including the N NSR requirements of the 2008 PM 2.5 

### NSR Implementation Rule, on June 2, 2014, the EPA published a final rulemaking that begins to address the remand of both rules

. See 79 FR 31566. The final rule classifies all existing 1997 and 2006 PM 2.5 

### NAAQS nonattainment areas as “Moderate” nonattainment areas and sets a deadline of December 31, 2014, for states to submit any SIP submissions, including nonattainment NSR SIPs, that may be necessary to satisfy the requirements of subpart 4, part D, title I of the CAA with respect to those 1997 and 2006 PM 2.5 

### NAAQS nonattainment areas.

In a separate rulemaking process which will follow the April 2014 rule, EPA is evaluating the requir ements of subpart 4 as they pertain to, among other things, nonattainment NSR for PM 2.5

6 706 F.3d 428 (D.C. Cir. 2013).

7 The 2007 implementation rule also addressed by the NRDC decision does not address any NSR requirements and is therefore not addressed by this rulemaking.

### 276 emissions. In particular, subpart 4 includes section 189(e) of the CAA, which requires the control of major stationary sources of PM 10 

### precursors “except where the Admi nistrator determines that such sources do not contribute significantly to PM 10 

### levels which exceed the standard in the area.” Under the court’s decision in NRDC , section 189(e) of the CAA also applies to PM 2.5



### . Notably, Oklahoma does not have any areas d esignated as nonattainment under either the 1997 or the 2006 PM 2.5 

### NAAQS. The obligation for a state to submit a plan addressing PM 2.5 

### nonattainment NSR permitting requirements under CAA section 189(a)(1)

– (2) only attaches when an area within a state has been designated nonattainment. Accordingly, Oklahoma is not required at this time to make any submissions addressing PM 2.5 

### nonattainment NSR permitting. The December 31, 2014 deadline for states to make any additional submission necessary to address the r equirements of subpart 4 as to the 1997 and 2006 PM 2.5 

### NAAQS, including addressing the regulation of PM 2.5 

### precursors pursuant to section 189(e), does not apply to Oklahoma

.
Nonetheless, as discussed above in our evaluation of the NNSR Definitions at OAC 252:100

- 8

- 51, the State of Oklahoma submitted a revision to the Oklahoma SIP on February 6, 2012 , which included revisions to definitions in the Oklahoma NNSR Permitting Program to address PM 2.5



### . The revised definition of “regulated NSR pollutant” at OAC 252:100

- 8

- 51 is consistent with the federal definition of “regulated NSR pollutant” at 40 CFR 51.165(a)(1)(xxxvii) and identifies precursors to PM 2.5 

### in nonattainment areas. With respect to PM 2.5 

### , the revised definition of “regulated pollutant” at OAC 252: 100

- 8

- 51 identifies sulfur dioxide and nitrogen oxides as regulated PM 2.5 

### precursors while volatile organic compounds (VOCs) and ammonia are not regulated PM 2.5 

### precursors in PM 2.5 

### nonattainment areas in Oklahoma. The February 6, 2012, submittal incorporat es by reference the definition of “significant” at 40 CFR 51.165(a)(1) as it exists on July 1, 2011, and will therefore include significant emission rates for direct PM 2.5 

### and for sulfur dioxide and nitrogen oxides as PM 2.5 

### precursors. These revisions, alt hough consistent with the 2008 NSR Rule as developed consistent with subpart 1 of the Act, may not contain the elements necessary to satisfy the CAA requirements when evaluated under the subpart 4 statutory requirements in the event an area in Oklahoma is designated nonattainment in the future. In particular, Oklahoma ’s submission does not include regulation of VOCs and ammonia as PM 2.5 

### precursors, nor does it include a demonstration consistent with section 189(e) showing that major sources of those precurs or pollutants would not contribute significantly to PM 2.5 

### levels exceeding the standard in the area. For these reasons, the EPA cannot conclude at this time that this part of the Oklahoma NNSR submission satisfies all of the requirements of subpart 4 as th ey pertain to PM 2.5 

### NNSR permitting. However, because PM 2.5 

### levels in Oklahoma do not currently exceed the standard, it is not necessary for the Oklahoma NNSR SIP at this time to fully address the requirements under CAA section 189. In the event that an ar ea is designated nonattainment for the 2012 PM 2.5 

### NAAQS or any other future PM 2.5 

### NAAQS, Oklahoma will have a deadline under section 189(a)(2) of the CAA to make a submission addressing the statutory requirements as to that area, including the requirements in section 189(e) that apply to the regulation of PM 2.5 

### precursors.
Although the revisions to Oklahoma ’s NNSR rule may not be required by the statute or contain all of the necessary elements to satisfy the CAA requirements when evaluated under the subpar t 4 provisions, the revisions themselves represent an enhancement of the currently SIP

- approved

vi. How do the revisions to the Oklahoma NNSR program satisfy the Required Increment Component of the PM 2.5 

### Increment

– SILs

– SMC Rule?

The EPA finalized the PM 2.5 

### PSD Increment

– SILs

– SMC Rule to provide additional regulatory requirements under the PSD SIP program regarding the implementation of the PM 2.5 

### NAAQS. See

, 75 FR 64864. The PM 2.5 

### PSD Increment

– SILs

– SMC Rule required states to submit SIP revisions to EPA by July 20, 2012, adopting provisions equivalent to or at least as stringent as the PM 2.5 

### PSD increments and the associated impleme nting regulations promulgated pursuant to section 166(a) of the CAA . More detail on the PM 2.5 

### PSD Increment

– SILs

– SMC Rule can be found in EPA’s October 20, 2010 final rule. See

, 75 FR 64864.
With respect to the NNSR Program, the October 20, 2010 final rule also codified the PM 2.5 

### SILs in the EPA’s regulations on new source review and permitting requirements at 40 CFR 51.165(b)(2). Unlike the PSD regulations (40 CFR 51.166 and 40 CFR 52.21), 40 CFR 51.165(b)(2) does not use the SILs to exempt a source fr om conducting cumulative air quality analysis. Instead, 40 CFR 51.165(b)(2) states that a proposed source or modification will be considered to cause a violation of a NAAQS when that source or modification would, at a minimum exceed the SIL in any area tha t does not or would not meet the applicable NAAQS. The revisions at OAC 252:100

- 8

- 52(a) incorporate by reference the federal requirements for SILs at 40 CFR 51.165(b)(2) as of December 20, 2010.

The EPA’s October 20, 2010 PSD for PM 2.5



### – I ncrement s, SILs and SMC Rule also provided that States could discretionarily choose to adopt and su bmit for EPA approval PM 2.5 

### SILs

, used as a screening tool to evaluate the impact a proposed new major source or major modification may have on the NAAQS or PSD increment, and /or a PM 2.5 

### SMC (also a screening tool) to determine the subsequent level of ambi ent air monitoring data gathering required for a PSD permit application for emissions of PM 2.5



### . On January 22, 2013, the U.S. Court of Appeals for the District of Columbia granted a request from the EPA to vacate and remand to the EPA portions of the fede ral PSD regulations (40 CFR 51.166(k)(2) and 52.21(k)(2)) setting forth provisions for implementing SILs for PM 2.5 

### so that the EPA could reconcile the inconsistency between the regulatory text and certain statements in the preamble to the 2010 final rule. Sierra Club v. EPA , 705 F.3d 458, 463

- 64 (D.C. Cir. 2013). The court declined to vacate the different portions of the federal PSD regulations (40 CFR 51.165(b)(2)) for implementing SILs for PM 2.5 

### that did not contain the same inconsistency in the regulator y text. Id. at 465

- 66. The court further vacated the portions of the PSD regulations (40 CFR 51.166(i)(5)(i)( c ) and 52.21(i)(5)(i)( c )) implementing a PM 2.5 

### SMC, finding that the EPA

### 278 lacked legal authority to adopt and use the PM 2.5 

### SMC to exempt permit applicants from the statutory requirement to compile and submit ambient monitoring data. Id . at 468

- 69. On December 9, 2013, EPA issued a good cause final rule formally removing the affected PSD SILs and SMC provisions from the CFR. S ee, 78 FR 73698. The court ruling and EPA’s subsequent good cause final rulemaking only addressed the PSD revisions of the October 20, 2010, final rule; therefore there will be no impact on the submitted revisions to the Oklahoma NNSR
program.

viii. How do the revisions to the Oklahoma NNSR program address the Fugitive Emissions Rule and subsequent EPA

- stays?

On December 19, 2008, the EPA issued a final rule revising the requirements of PSD and NNSR program regarding the treatment of fugitive emissions (Fugitive Emissions Rule, 73 FR 77882)). The Fugitive Emissions Rule required fugitive emissions to be included in determining whether a physical or operational change results in a major modification only for sources in industries that have been designated through rulemaking under section 302(j) of the CAA. Previously, the EPA rules required that fugitive emissions be included in major modification applicable determinations for all source categories.
On February 17, 2009, the Natural Resources Defense Counc il (NRDC) submitted a petition for reconsideration of the December 2008 Fugitive Emissions Rule. On April 24, 2009, the EPA responded to the petition by letter indicating we were convening a reconsideration proceeding for the December 2008 Fugitive Emissio ns Rule and granted a 3

- month administrative stay of the rule provisions. The initial 3

- month administrative stay of the Fugitive Emissions Rule became effective on September 30, 2009. See 74 FR 50115. An interim final rule extending the administrative sta y for an additional 3 months became effective on December 31, 2009. See 74 FR 5265692. An additional 18 month stay was finalized on March 31, 2010. See 75 FR 16012.
The EPA finalized a final rule on March 30, 2011, titled PSD and NNSR: Reconsideratio n of I nclusion of Fugitive Rule. See
, 76 FR 17548 . This final action stayed indefinitely the provisions of the December 2008 Fugitive Emissions Rule. Following is a summary of how the Oklahoma NNSR program addresses fugitive emissions.

• The Oklahoma NNSR program does not include the revisions to “major modification” or “net emissions increase” promulgated by EPA in the December 2008 Fugitive Emissions Rule at 40 CFR 51.165(a)(1)(v)(G) or 40 CFR 51.165(a)(1)(vi)(C)(3), respectively. As such, the Oklahoma NNSR prog ram does not include the provisions that are indefinitely stayed.

• The Oklahoma NNSR program continues to require fugitive emissions to be included in the major modification applicability determinations for all source categories.

o The Oklahoma NNSR program at OAC 252:100

- 8

- 51 incorporates by reference the federal NNSR definitions for “major stationary source

, ” “fugitive emissions

, ” and “ projected actual emissions ” as of July 1, 2010. The Oklahoma NNSR program does not IBR the definition of baseline actual emissions, rather the

### 279 NNSR program relies on the Oklahoma PSD definition at OAC 252:100

- 8

- 31 for the definition of baseline actual emissions.

o The applicability p rovisions at OAC 252:100

- 8

- 50 have been evaluated elsewhere in this TSD and determined to be consistent with federal requirements for NNSR.

o The Oklahoma NNSR program at OAC 252:100

- 8

- 53 incorporates by reference the requirements of 40 CFR 51.165(a)(4) rega rding the exemption of fugitive emissions in determining whether a source or modification is major as of July 2, 2007. The Oklahoma NNSR program source obligations at OAC 252:100

- 8

- 55incorporates by reference the requirements of 40 CFR 51.165(a)(6)(i) thro ugh (v) as of July 2, 2007. Additio na lly the Oklahoma NNSR program at OAC 252:100

- 8

- 57 incorporates by reference the requirements at 40 CFR 51.165(f) regarding actuals PALs as of July 2, 2007.

### 280 

# III. Conclusion

The technical analysis provided in the preceding sections has compared the applicable sections of the CAA and 40 CFR part 51 with the Oklahoma SIP submittals dated June 24, 2010; July 16, 2010; December 27, 2010; February 6, 2012; and January 18, 2013. The EPA’s analysis found that the propose d revisions to the Oklahoma SIP should be approved as consistent with federal requirements. Accordingly, the EPA should propose approval of the following revisions:
