ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: The Environmental Protection Agency (EPA) is proposing limited revisions to the source-specific Federal Implementation Plan (FIP) that was promulgated to regulate air pollutant emissions from the Four Corners Power Plant (FCPP), a coal-fired power plant located on the reservation lands of the Navajo Nation, near Farmington, New Mexico. These limited revisions propose to make certain provisions of the FIP consistent with national actions and rulemakings promulgated since 2012; update the FIP to reflect recent operating changes; and add new provisions to the FIP to include the air pollution control requirements for FCPP of a Consent Decree entered in the United States District Court for the District of New Mexico on August 17, 2015.

Action In today's action, the EPA is proposing limited revisions to the FIP for FCPP that we promulgated on May 7, 2007 (``2007 FIP'') and August 24, 2012 (``2012 FIP'').\1\ The 2007 and 2012 regulations are codified in the Code of Federal Regulations (CFR) at 40 CFR 49.5512, and we refer collectively to the provisions from the 2007 and 2012 actions as the ``FIP'' or the ``FCPP FIP.'' The EPA established federally enforceable emission limitations for particulate matter (PM), sulfur dioxide (SO2 ), oxides of nitrogen (NOX ), and opacity in the FCPP FIP. --------------------------------------------------------------------------- \1\ See 72 FR 25698 (May 7, 2007) and 77 FR 51620 (August 24, 2012). --------------------------------------------------------------------------- The EPA is proposing revisions to the FIP for several reasons: (1) To make certain provisions in the FIP consistent with national actions and rulemakings promulgated since 2012; (2) to update the FIP to reflect recent operating changes; and (3) to add new provisions to the FIP to include the air pollution control requirements for FCPP of a Consent Decree (``Consent Decree'') entered in the United States District Court for the District of New Mexico on August 17, 2015.\2\ --------------------------------------------------------------------------- \2\ See Consent Decree for Dine CARE v. Arizona Public Service Company and EPA v. Arizona Public Service Company, US District Court for the District of New Mexico, Case No. 1:11-cv-00889-JB-SCY (August 17, 2015). --------------------------------------------------------------------------- To update the FCPP FIP for consistency with national actions and rulemakings, we are proposing to remove: (1) Emission limit exemptions that apply during periods of startup and shutdown; (2) a provision allowing for an affirmative defense during periods of malfunctions; and (3) exemptions for water vapor from the opacity standard and monitoring and reporting requirements.\3\ These revisions, if finalized, would make the FCPP FIP consistent with the EPA's interpretations of Clean Air Act (CAA, or ``the Act'') requirements, as reflected in the Agency's recent action concerning how provisions in state implementation plans (SIPs) treat excess emissions during startup, shutdown, and malfunctions (``2015 SSM Action'').\4\ --------------------------------------------------------------------------- \3\ See 72 FR 25705 (May 7, 2007) and 40 CFR 49.5512(h)(2) and (h)(3), and 40 CFR 49.5512(c)(7). \4\ See 80 FR 33840 (June 12, 2015). --------------------------------------------------------------------------- The EPA is also proposing to update the testing requirements for PM in the FCPP FIP to be consistent with PM testing requirements promulgated nationally in the Mercury and Air Toxics Standards (MATS) Rule.\5\ The revisions to the PM testing requirements, if finalized, would increase the frequency of PM testing in the FIP to match the MATS Rule, allow the operator the option to demonstrate compliance using alternative methods, e.g., PM continuous emission monitoring systems (PM CEMS), and streamline the existing PM testing requirements. --------------------------------------------------------------------------- \5\ See 77 FR 9303 (February 16, 2012) and 81 FR 20172 (April 6, 2016) (Final Technical Corrections). --------------------------------------------------------------------------- In order to update the FIP to reflect the current operation of FCPP, we are proposing to add a statement to the applicability section of the FIP to clarify that Units 1, 2 and 3 have been permanently retired, and to remove certain provisions related to Units 1, 2, and 3 from the FIP that are no longer applicable following the permanent retirement of those units. The operator of FCPP removed those units from service by January 1, 2014 to comply with the requirements in the 2012 FIP that the EPA promulgated to address the Best Available Retrofit Technology (BART) provisions of the Regional Haze Rule for NOX .\6\ These revisions, if finalized, would enhance regulatory clarity by removing requirements that apply to emission units that have permanently ceased operation. --------------------------------------------------------------------------- \6\ See 77 FR 51620 (August 24, 2012) and 40 CFR 49.5512(i)(3). --------------------------------------------------------------------------- The final changes in this proposed rulemaking are to add new provisions to the FCPP FIP to reflect requirements in the Consent Decree. Generally, the Consent Decree requires greater emission reductions of SO2 , NOX , and PM by establishing lower emission limitations than the existing limitations in the FIP for these pollutants. The Consent Decree requires the operator of the facility to request that the EPA amend the FCPP FIP to incorporate the requirements and limitations from the Consent Decree. These proposed revisions, if finalized, would make the emission limitations and other requirements from the Consent Decree federally enforceable. B. Facility FCPP is a coal-fired power plant located on the Navajo Nation Indian Reservation, just west of Farmington, New Mexico, and it is co- owned by several entities and operated by Arizona Public Service (APS).\7\ The facility includes two units, Units 4 and 5, each with a capacity of 770 megawatts (MW) net generation, providing a total capacity of 1540 MW.\8\ Operations at the facility produce emissions of air pollutants, including SO2 , NOX , and PM. Existing pollution control equipment on Units 4 and 5 include [[Page 86990]] baghouses for PM control, lime spray towers (``scrubbers'') for SO2 control, and low-NOX burners for limiting NOX formation during the combustion process. FCPP is in the process of installing selective catalytic reduction (SCR) on Units 4 and 5 for additional NOX emission reductions to comply with the ``better than BART'' provisions of the 2012 FIP (under 40 CFR 49.5512(i)(3)) and with the Consent Decree. --------------------------------------------------------------------------- \7\ FCPP is currently co-owned by Arizona Public Service, Public Service Company of New Mexico, Salt River Project, Tucson Electric Power, and El Paso Electric Company. \8\ APS retired Units 1-3 (total capacity of 560 MW) at FCPP in January 2014 as part of a ``better than BART'' alternative it suggested to the EPA. For more information on the EPA's ``better than BART'' determination, please see 77 FR 51620 (August 24, 2012). --------------------------------------------------------------------------- C. Attainment Status FCPP is located in the Four Corners Interstate air quality control region, which is designated attainment for all criteria pollutants under the CAA.\9\ --------------------------------------------------------------------------- \9\ See 40 CFR 81.332. --------------------------------------------------------------------------- D. The EPA's Authority To Promulgate a FIP in Indian Country When the CAA was amended in 1990, Congress included a new provision, section 301(d), granting the EPA authority to treat tribes in the same manner as states where appropriate.\10\ In 1998, the EPA promulgated regulations known as the Tribal Authority Rule (TAR).\11\ The EPA's promulgation of the TAR clarified, among other things, that state air quality regulations generally do not, under the CAA, apply to facilities located anywhere within the exterior boundaries of Indian reservations.\12\ Prior to the addition of section 301(d) and promulgation of the TAR, some states had mistakenly included emission limitations in their SIPs that they may have believed could apply under the CAA to private facilities operating on adjacent Indian reservations. --------------------------------------------------------------------------- \10\ See 40 U.S.C. 7601(d). \11\ See 40 CFR parts 9, 35, 49, 50 and 81. See also 63 FR 7254 (February 12, 1998). \12\ See 63 FR 7254 at 7258 (noting that unless a state has explicitly demonstrated its authority and has been expressly approved by the EPA to implement CAA programs in Indian country, the EPA is the appropriate entity to implement CAA programs prior to tribal primacy), Arizona Public Service Company v. EPA., 211 F.3d 1280 (D.C. Cir. 2000), cert. denied sub nom, Michigan v. EPA., 532 U.S. 970 (2001) (upholding the TAR); see also Alaska v. Native Village of Venetie Tribal Government, 533 U.S. 520, 526 n.1 (1998) (primary jurisdiction over Indian country generally lies with federal government and tribes, not with states). --------------------------------------------------------------------------- In the preambles to the proposed and final 1998 TAR, the EPA generally discusses the legal basis in the CAA that authorizes the EPA to regulate sources of air pollution in Indian country.\13\ The EPA concluded that the CAA authorizes the EPA to protect air quality throughout Indian country.\14\ In fact, in promulgating the TAR, the EPA specifically provided that, pursuant to the discretionary authority explicitly granted to the EPA under sections 301(a) and 301(d)(4) of the Act, the EPA ``[s]hall promulgate without unreasonable delay such federal implementation plan provisions as are necessary or appropriate to protect air quality, consistent with the provisions of sections 304(a) [sic] and 301(d)(4), if a tribe does not submit a tribal implementation plan meeting the completeness criteria of 40 CFR part 51, Appendix V, or does not receive EPA approval of a submitted tribal implementation plan.'' \15\ --------------------------------------------------------------------------- \13\ See 59 FR 43956 (August 25, 1994); 63 FR 7253 (February 12, 1998). \14\ See 63 FR 7253 at 7262 (February 12, 1998); 59 FR 43956 at 43960-43961 (August 25, 1994) (citing, among other things, to CAA sections 101(b)(1), 301(a), and 301(d)). \15\ See 63 FR at 7273 (codified at 40 CFR 49.11(a)). In the preamble to the final TAR, the EPA explained that it was inappropriate to treat Tribes in the same manner as states with respect to section 110(c) of the Act, which directs the EPA to promulgate a FIP within 2 years after the EPA finds a state has failed to submit a complete state plan or within 2 years after the EPA disapproval of a state plan. Although the EPA is not required to promulgate a FIP within the 2-year period for tribes, the EPA promulgated 40 CFR 49.11(a) to clarify that the EPA will continue to be subject to the basic requirement to issue any necessary or appropriate FIP provisions for affected tribal areas within some reasonable time. See 63 FR at 7264-65. --------------------------------------------------------------------------- E. Historical Overview of FCPP FIP Actions On September 8, 1999, the EPA proposed a source-specific FIP for FCPP.\16\ The 1999 proposed FIP stated: ``Although the facility has been historically regulated by New Mexico since its construction, the state lacks jurisdiction over the facility or its owners or operations for CAA compliance or enforcement purposes.'' The EPA intended for the 1999 FIP to ``federalize'' the emission limitations that New Mexico had erroneously included in its SIP.\17\ The EPA received comments on the proposed 1999 FIP. However, at that time, concurrent negotiations between an environmental non-governmental organization, APS, and the Navajo Nation resulted in an agreement by APS to voluntarily increase the SO2 removal efficiency from the scrubbers at FCPP. The EPA did not take final action on the 1999 proposal. --------------------------------------------------------------------------- \16\ See 64 FR 48731 (September 8, 1999). \17\ Id. at 48733. --------------------------------------------------------------------------- In 2006, the EPA proposed a new source-specific FIP for FCPP and took action to finalize it in 2007.\18\ This new FIP imposed federally enforceable emission limitations for SO2 , based on the increased scrubber SO2 removal efficiency (72 to 88 percent), and for PM, based on the PM emission limitation from the New Mexico SIP. The 2006 proposed FIP also established an emission limitation for opacity and a requirement for control measures to limit dust emissions from coal handling and storage facilities, flyash handling and storage facilities, and from road-sweeping activities. In addition, the 2006 proposed FIP contained NOX emission limitations that already applied to FCPP as part of the Acid Rain Program created in the 1990 CAA Amendments. --------------------------------------------------------------------------- \18\ See 72 FR 25698 (May 7, 2007), codified at 40 CFR 49.5512(a)-(h). --------------------------------------------------------------------------- On August 24, 2012, the EPA promulgated a final rule that established limits for NOX emissions from FCPP under the BART provision of the Regional Haze Rule, as well as control measures to limit emissions of dust.\19\ The final rule required the owners of FCPP to choose between two strategies for BART compliance: (1) Compliance with a plant-wide BART emission limitation of 0.11 pounds of NOX per million British thermal units of heat input (lb/ MMBtu) by October 23, 2017, or (2) retirement of Units 1, 2, and 3 by January 1, 2014 and compliance with a BART emission limitation for NOX of 0.098 lb/MMBtu on Units 4 and 5 by July 31, 2018. The second BART compliance strategy, involving retirement of Units 1, 2, and 3, was based on a plan originally put forth by APS. This compliance strategy was proposed and finalized as an alternative emission control strategy that achieved greater reasonable progress than BART (``better than BART'').\20\ APS permanently ceased operation of Units 1, 2, and 3 at FCPP by January 1, 2014, and is currently engaged in the process of installing SCR on Units 4 and 5 to meet the applicable NOX emission limitations. --------------------------------------------------------------------------- \19\ See 77 FR 51620 (August 24, 2012). \20\ For additional information regarding the EPA's analyses regarding BART and the alternative emission control strategy, see the EPA's BART proposal (75 FR 64221, October 29, 2010), supplemental proposal (76 FR 10530, February 25, 2011) and final rule (77 FR 51620, August 24, 2012). --------------------------------------------------------------------------- The provisions of the 2007 FIP are codified at 40 CFR 49.5512(a)- (h).\21\ The BART provisions of the 2012 FIP are codified at 40 CFR 49.5512(i), and the dust control measures from the 2012 FIP are codified at 40 CFR 49.5512(j). --------------------------------------------------------------------------- \21\ The 2007 FIP was originally codified at 40 CFR 49.23. On April 29, 2011, the FCPP FIP was redesignated to 40 CFR 49.5512 at 76 FR 23879 (April 29, 2011). --------------------------------------------------------------------------- II. Basis for Proposed Action In this proposed FIP revision, the EPA is exercising its discretionary authority under sections 301(a) and 301(d)(4) of the CAA and 40 CFR 49.11(a). The EPA is proposing to find that it is ``necessary or appropriate'' to revise the FCPP FIP, because it contains certain provisions [[Page 86991]] that are inconsistent with more recent actions and rulemakings promulgated by the EPA in the MATS Rule and the statutory requirements of the CAA, as reflected in the 2015 SSM Action. Thus, these provisions of the current FCPP FIP are inconsistent with current requirements and need to be revised to make them consistent with regulatory and statutory requirements. The EPA is also concerned that that these inconsistencies create confusion and could lead to regulatory uncertainty by the source, regulators, courts, or affected members of the public. Additionally, the Consent Decree requires APS to submit a request to the EPA to amend its FIP to include requirements of the Consent Decree. APS submitted its request on June 9, 2016.\22\ The EPA is also proposing to find that it is ``necessary or appropriate'' to revise the FIP at this time to include the Consent Decree provisions. For the reasons set forth above, we are proposing to find that limited revisions to the FIP for FCPP are ``necessary or appropriate'' to further protect air quality on the Navajo Nation. --------------------------------------------------------------------------- \22\ See ``Request to Include Consent Decree in Four Corners Federal Implementation Plan'' from Thomas H. Livingston, Fossil Plant Manager and Responsible Official, to Elizabeth Adams, Acting Director, Air Division, EPA Region IX, dated June 9, 2016. --------------------------------------------------------------------------- III. Summary of Proposed FIP Revisions A. Proposed FIP Revisions The EPA is proposing limited revisions to the FCPP FIP at 40 CFR 49.5512 described as follows. We have included a document in the docket for this rulemaking that shows the original text of 40 CFR 49.5512 and the EPA's proposed revisions to that text.\23\ --------------------------------------------------------------------------- \23\ See document titled ``2016_1118 FCPP FIP existing reg text RLSO'' in the docket for this proposed rulemaking. --------------------------------------------------------------------------- 1. Revisions to 40 CFR 49.5512(a) In the applicability section of the FIP, the EPA is proposing to add a statement that Units 1, 2, and 3 at FCPP permanently ceased operation by January 1, 2014 pursuant to the requirements of 40 CFR 49.5512(i)(3). 2. Revisions to 40 CFR 49.5512(c) The EPA is proposing to: (1) Specify that the definitions in paragraph (c) of 40 CFR 49.5512(c) apply to paragraphs (a) through (j) of 40 CFR 49.5512; (2) delete the definition of affirmative defense at 40 CFR 49.5512(c)(1); and (3) delete the portion of the definition of malfunction that provides for an affirmative defense for malfunctions at 40 CFR 49.5512(c)(7). We are also proposing to delete portions of the definitions for shutdown (at 40 CFR 49.5512(c)(12)) and startup (at 40 CFR 49.5512(c)(13)) that relate to Units 1, 2, and 3. 3. Revisions to 40 CFR 49.5512(d) The EPA is proposing to add a statement that the emission limitations under 40 CFR 49.5512(d) apply to FCPP at all times. Under 40 CFR 49.5512(d)(2), we are proposing to delete the portion of the PM emission limitation that provides detailed specifications, i.e., test duration and minimum collection volume, related to PM testing. The EPA is also proposing to delete the dust provisions in 40 CFR 49.5512(d)(3). Under 40 CFR 49.5512(d)(4), we are proposing to delete the exclusion of uncombined water droplets from the opacity standard and to add a provision stating that any unit for which the owner or operator installs, calibrates, maintains, and operates a PM CEMS to demonstrate compliance with emission limitations for PM will be exempt from the opacity standard. Finally, the EPA is proposing to delete the portion of the emission limitation for NOX under 40 CFR 49.5512(d)(5)(i) that applied to Units 1, 2, and 3. 4. Revisions to 40 CFR 49.5512(e) Paragraph (e) of 40 CFR 49.5512 addresses testing and monitoring and generally uses sub-paragraphs (e)(1)-(e)(8) to outline pollutant- specific requirements to ensure compliance with the emission limitations in paragraph (d). Under 40 CFR 49.5512(e), the EPA is proposing to delete specific provisions for PM testing and move revised provisions for PM testing to 40 CFR 49.5512(e)(3). Also under 40 CFR 49.5512(e), we are proposing to remove provisions that exempt units from opacity monitoring requirements during periods when the stack is saturated and also to remove a presumption that high opacity readings that occur when the baghouse is operating within normal parameters are caused by water vapor and shall not be considered a violation. In addition, we are proposing to move the opacity monitoring requirements from 40 CFR 49.5512(e) to 40 CFR 49.5512(e)(6). In paragraph 49.5512(e)(1), we are proposing to delete provisions that specify the compliance deadline for installing CEMS for SO2 and NOX because CEMS for those pollutants have already been installed at FCPP. In paragraph (e)(3), we are proposing to revise the testing requirements for PM to be consistent with the three options for PM testing under the MATS Rule in 40 CFR part 63 subpart UUUUU. In paragraph (e)(6), we are proposing to clarify that (e)(6) applies if the opacity standard in paragraph (d)(4) is applicable, i.e., if the owner or operator has not elected to install and certify PM CEMS for demonstrating compliance with PM emission limitations. In addition, we are revising the opacity monitoring requirements in (e)(6) to provide three options for determining compliance with the opacity standard, if the opacity standard applies. Because Units 1, 2, and 3 at FCPP have permanently ceased operation, the EPA is also proposing to delete the testing requirements for those units in paragraph (e)(8). 5. Revisions to 40 CFR 49.5512(f) The EPA is proposing revisions to the reporting and recordkeeping requirements to provide additional clarity that all reports and notifications required in paragraph (f), (f)(4), and (f)(4)(ii) should be reported to the Navajo Nation Environmental Protection Agency (NNEPA) and the EPA. We are also revising paragraph (f) to require that the Air Division and the Enforcement Division within the Region IX office of the EPA be provided reports and notifications. Paragraph (f)(1) includes CEMS notification and recordkeeping requirements, and we are proposing to add notification and recordkeeping requirements for the Continuous Opacity Monitoring Systems (COMS) and visible emission testing. In addition, we are also proposing to delete the water vapor exemptions in paragraphs (f)(4)(i) and (f)(4)(i)(H). Finally, paragraph (f)(4)(i)(G) requires written reports to include opacity exceedances from the COMS, and we are proposing to also require reporting of opacity exceedances from the visible emission performance tests. 6. Revisions to 40 CFR 49.5512(h) The EPA is proposing to delete the startup and shutdown exemptions for opacity and PM at paragraph (h)(2), and to delete the provisions related to an affirmative defense for malfunctions in paragraph (h)(3). 7. Revisions to 40 CFR 49.5512(i) The EPA is proposing to delete the technical specifications in paragraph (i)(1) for annual PM testing and require that PM testing be performed in accordance with paragraph (e)(3) of 49.5512, which requires either testing using procedures in accordance with the MATS Rule at 40 CFR part 63 subpart UUUUU, or the installation, calibration, maintenance, and operation of a continuous parametric monitoring system (CPMS) or a CEMS for PM. In [[Page 86992]] addition, under paragraph (i)(2)(iii), we are proposing to correct a typographical error. 8. Addition of 40 CFR 49.5512(k) The EPA is proposing to promulgate paragraph (k) to add emission limitations and other provisions from the Consent Decree to the FCPP FIP. B. Justification for Proposed FIP Revisions 1. Revisions to 40 CFR 49.5512(a) The EPA is proposing to add a statement to the applicability paragraph of the FIP that Units 1, 2, and 3 at the Four Corners Power Plant permanently ceased operation by January 1, 2014 pursuant to the requirements of 40 CFR 49.5512(i)(3). This proposed revision is intended to update the FIP to reflect current operation at FCPP. The EPA's 2012 FIP for Regional Haze required FCPP to comply with either emission limitations for BART, achievable with the installation of SCR on all five units at FCPP, or a ``better than BART'' alternative.\24\ The operator of FCPP elected to comply with the alternative. Under the alternative, the operator retired Units 1, 2, and 3 by January 1, 2014, and has begun the process to install SCR on the Units 4 and 5. --------------------------------------------------------------------------- \24\ See 40 CFR 49.5512(i)(2) and (3). See also 77 FR 51620 (August 24, 2012). --------------------------------------------------------------------------- Units 1, 2, and 3 have not been operated since January 1, 2014, and the operator has been begun the process to dismantle those units. Accordingly, it is reasonable to add a statement regarding the status of those units. This revision, if finalized as proposed, would not relax any requirement or affect the stringency of the FIP. This proposed change to update the FIP would not have any effect on air quality in the area surrounding FCPP. 2. Revisions to 40 CFR 49.5512(c) Paragraph (c) defines certain terms used in the FIP. As discussed elsewhere, the EPA is proposing to add a new paragraph (k) that includes provisions, including a separate set of definitions, from the Consent Decree. Therefore, to avoid confusion associated with slight differences that may exist between terms common to both sets of definitions, we are proposing to specify that the definitions in paragraph (c) apply to paragraph (a) through (j). This revision, if finalized as proposed, would not relax any requirement or affect the stringency of the FIP, and would not have any effect on air quality in the area surrounding FCPP. Consistent with the proposed revisions to paragraph (a), the EPA is proposing to remove portions of definitions for shutdown and startup (at paragraph (c)(12) and (13)), related to Units 1, 2, and 3, in order to update the FIP to reflect current operating conditions. Because these units were retired by January 1, 2014, these revisions, if finalized as proposed, would not relax any requirements or affect the stringency of the FIP as contemplated by CAA section 110(l). These proposed changes to update the FIP would not have any effect on air quality in the area surrounding FCPP. The EPA is also proposing to remove definitions and provisions in paragraph 49.5512(c) that provide an affirmative defense for malfunction episodes. After the EPA's promulgation of the 2007 FIP, the United States Court of Appeals for the District of Columbia (``D.C. Circuit'') ruled that CAA sections 113 (federal enforcement) and 304 (citizen suits) preclude EPA from creating affirmative defense provisions in the Agency's own regulations imposing emission limitations on sources.\25\ The D.C. Circuit found that such affirmative defense provisions purport to alter the jurisdiction of federal courts to assess liability and impose penalties for violations of those limits in private civil enforcement cases. The D.C. Circuit's holding makes clear that the CAA does not authorize promulgation of such a provision by the EPA. In particular, the D.C. Circuit's decision turned on an analysis of CAA sections 113 and 304. These provisions apply with equal force to a civil action brought to enforce the provisions of a FIP. The logic of the D.C. Circuit's decision thus applies to the promulgation of a FIP, and precludes the EPA from including an affirmative defense provision in a FIP.\26\ For these reasons, the EPA is proposing to delete the provision in the FIP that provides an affirmative defense for exceedances of emission limitations that occur during malfunctions at FCPP. This proposed revision, if finalized, will not relax any requirements in the FIP and would not have any adverse effects on air quality in the area. Additionally, by removing an inconsistency between the FIP and the EPA's more recently promulgated regulations and the 2015 SSM Action, the proposed revision provides more clarity and certainty. --------------------------------------------------------------------------- \25\ See NRDC v.

Cir. 2014). \26\ See February 4, 2013 Memorandum to Docket EPA-HQ-OAR-2012- 0322: ``State Implementation Plans: Response to Petition for Rulemaking; Findings of Substantial Inadequacy; and SIP Calls to Amend Provisions Applying to Excess Emissions During Periods of Startup, Shutdown, and Malfunction; Statutory, Regulatory, and Policy Context for this Rulemaking.'' --------------------------------------------------------------------------- 3. Revisions to 40 CFR 49.5512(d) The EPA is proposing to add a statement to make clear that the emission limitations under 40 CFR 49.5512(d) apply continuously and at all times. Exemptions from emission limitations during any mode of source operation are contrary to CAA requirements. CAA section 110(a)(2)(A) requires SIPs to include, among other requirements, ``enforceable emission limitations.'' Section 302(k) of the CAA defines an emission limitation as: ``a requirement established by the State or the Administrator which limits the quantity, rate, or concentration of emissions of air pollutants on a continuous basis, including any requirement relating to the operation or maintenance of a source to assure continuous emission reduction, and any design, equipment, work practice or operational standard promulgated under this Act.'' The courts have held that the plain meaning of the term ``continuous'' does not allow exemptions from emission limitations.\27\ For these reasons, the EPA is proposing to add a statement to clarify in 40 CFR 49.5512(d) that the emission limitations in that paragraph apply at all times. This proposed revision, if finalized, would strengthen the existing emission limitations by clarifying that the limits are applicable at all times, including during periods of startup and shutdown. --------------------------------------------------------------------------- \27\ See, e.g., Sierra Club v. Johnson, 551 F.3d 1019 (D.C. Cir. 2008); US Magnesium, LLC v. EPA, 690 F.3d 1157 (10th Cir. 2012). This issue is discussed at length in ``Memorandum to Docket EPA-HQ- OAR-2012-0322, Statutory, Regulatory, and Policy Context for this Rulemaking,'' February 4, 2013. --------------------------------------------------------------------------- Under paragraph (d)(2), the EPA is proposing to delete the portion of the PM emission limitation that specifies requirements related to the test duration and minimum collection volume for PM testing. Generally, the testing requirements for PM and other pollutants are found in paragraph (e). To improve clarity of the regulation, the EPA is proposing to delete the provisions in paragraph (d)(2) that relate to testing and rely solely on paragraph (e) to specify the requirements for test methods. This proposed revision, if finalized, would not relax any requirements and would not affect air quality in the area surrounding FCPP. Under paragraph (d)(3), we are proposing to delete the requirements for dust control. The EPA promulgated paragraph (d)(3) as part of the 2007 FIP. Following final action on the 2007 FIP, the operator of FCPP filed a petition for review, claiming, among other things, [[Page 86993]] that the EPA had not provided an adequate explanation for promulgating the dust control requirements.\28\ In the litigation, the EPA agreed that the dust control requirements should be remanded and vacated because the 2007 FIP did not contain an adequate explanation of its rationale. On November 13, 2008, the EPA issued a final rule to stay the effectiveness of the dust control requirements at paragraph (d)(3).\29\ In the EPA's 2012 action to implement the BART requirements for FCPP, the EPA proposed and finalized dust control measures in the FCPP FIP at paragraph (j) that were consistent with the requirements in paragraph (d)(3) requiring submission of a dust control plan and compliance with a 20-percent opacity limit.\30\ The proposal provided the EPA's rationale for establishing dust control requirements, and these requirements were not challenged in the final 2012 FIP. Because the requirements in paragraph (d)(3) were stayed in 2008 and replaced by paragraph (j) in 2012, which remains in effect, the EPA's proposal to remove the dust control requirements at paragraph (d)(3) would not relax any requirements and would not have any effects on air quality in the area surrounding FCPP. --------------------------------------------------------------------------- \28\ Arizona Public Service Company v. EPA et al., 562 F.3d 1116, Case No. 07-9546, (10th Circuit, Apr. 14, 2009). \29\ See 73 FR 67107 (November 13, 2008). \30\ See 75 FR 64211 (October 19, 2010) and 77 FR 51620 (August 12, 2012). --------------------------------------------------------------------------- Paragraph (d)(4) establishes a requirement that the discharge of emissions from the stacks of Units 4 and 5 shall not exhibit greater than 20 percent opacity, excluding uncombined water droplets. We are proposing to delete the exclusion of uncombined water droplets from the opacity standard. This specific exclusion of water vapor is inconsistent with the 2015 SSM Action. The exclusion is also inconsistent with the EPA's treatment of opacity in other rulemakings. For example, although FCPP is not subject to the New Source Performance Standard (NSPS) for electric generating units at 40 CFR part 60 subpart Da, the subpart Da standard does not include a specific exclusion for water vapor in the opacity standard.\31\ However, it does include provisions for addressing interference of water vapor with the COMS by providing alternative monitoring requirements to assure continuous monitoring of baghouse performance.\32\ In addition, subpart B to 40 CFR part 75 includes an exemption from the opacity monitoring requirements of part 75 (i.e., COMS) for units with wet flue gas pollution control systems where it is demonstrated that condensed water is present and impedes the accuracy of opacity measurements.\33\ Generally, these alternatives for addressing water vapor interference would be invoked for systems that consistently experience saturated stack conditions. --------------------------------------------------------------------------- \31\ See 40 CFR part 60 subpart Da at 60.42Da(b). Subpart Da to part 60 is the ``Standard of Performance for Electric Utility Steam Generating Units'' and applies to units that are capable of combusting more than 73 MW heat input of fossil fuel and for which construction, modification, or reconstruction commenced after September 18, 1978. The units at FCPP were constructed prior to 1978 and are not subject to part 60 subpart Da. \32\ See 40 CFR part 60 subpart Da 60.49Da(a). \33\ See 40 CFR part 75 subpart B at 75.14. --------------------------------------------------------------------------- The EPA promulgated the exclusion of uncombined water droplets in the 2007 FIP to address the technical challenge at FCPP associated with the use of COMS to monitor opacity when the stacks are saturated.\34\ Currently, the scrubbers for SO2 control at FCPP operate with a bypass specifically to avoid saturated stack conditions given the physical limitations of the existing unlined stacks.\35\ Furthermore, we understand from the operator of FCPP that Units 4 and 5 infrequently experience high opacity readings as a result of water vapor interference, and the limited instances generally resulted from equipment or process issues.\36\ --------------------------------------------------------------------------- \34\ See 72 FR 25698 at 25701 (May 7, 2007). \35\ We note that the Consent Decree requires the operator to modify the existing ductwork at FCPP to withstand saturated conditions in order to eliminate the bypass. See proposed regulatory text at 40 CFR 49.5512(k)(3)(ii). \36\ See document titled ``Opacity Exceedances due to Saturated Stack.docx,'' in the docket for this rulemaking, showing three opacity exceedances from Units 4 and 5 combined due to wet stack conditions over 2011-2015, generally resulting from equipment malfunction. --------------------------------------------------------------------------- The EPA is proposing to remove the provisions exempting water vapor from the opacity standard and the associated monitoring and reporting requirements because these exemptions are inconsistent with the 2015 SSM Action, stating that emission standards must apply at all times, including periods of malfunction. Our proposal, to remove the water vapor exemption from the opacity standard and monitoring requirements, represents a strengthening of the FIP. Therefore, we anticipate that this proposed revision would not have any adverse effects on air quality in the surrounding area. Under paragraph (d)(4), we are also proposing to add a provision that any unit for which the owner or operator installs, calibrates, maintains, and operates a PM CEMS to demonstrate compliance with a PM emission limitation shall be exempt from the opacity standard in paragraph (d)(4), and the associated monitoring and recordkeeping requirements in paragraphs (e) and (f). This provision is consistent with the provisions of the NSPS at 60.42Da(b)(1) and the Acid Rain Program requirements at 40 CFR 75.14(e), which generally provides that any owner or operator that elects to install, calibrate, maintain, and operate a CEMS for measuring PM emissions is exempt from the opacity standard and monitoring requirements.\37\ The PM CEMS is a monitoring system that provides a continuous assessment of compliance with a PM limit. Generally, opacity standards and COMS have been used as a surrogate to ensure continuous compliance with a PM emission standard that would otherwise be subject to periodic source testing.\38\ As noted above, FCPP is not subject to the NSPS at 60.42Da. However, we are proposing to follow the same rationale from Subpart Da to exempt any unit from the opacity standard and COMS requirement if a PM CEMS is installed on that unit and used for determining continuous compliance with its PM emission limitation. --------------------------------------------------------------------------- \37\ See also 77 FR 9304 (February 16, 2012). \38\ See, e.g., discussion of opacity in the 2007 FIP for FCPP, 72 FR 25698 at 25701 (May 7, 2007), stating that opacity limits are generally applied to ensure a unit is meeting its PM limit. --------------------------------------------------------------------------- As discussed elsewhere in this proposed rule, the Consent Decree requires the operator of FCPP, by early 2017, to install PM CEMS and, by mid-2018, to make modifications to the stacks to withstand saturated conditions to allow greater SO2 removal efficiency (by reducing or eliminating the existing scrubber bypass). After these stack modifications are made in 2018, we anticipate that the units at FCPP will more consistently experience saturated stack conditions that may impede the accuracy of opacity measurements. We consider the use of PM CEMS to be an improvement upon the use of an opacity standard and COMS as a surrogate for measuring continuous compliance with PM limits, particularly for wet stacks. Therefore, the EPA does not consider these revisions to relax any requirements or to result in any adverse effects on air quality in the surrounding area. The last proposed revision under paragraph (d) is to remove the emission limitation for NOX that applied to Units 1, 2, and 3 at FCPP under 40 CFR 49.5512(d)(5)(i). The owner or operator permanently ceased operation of Units 1, 2, and 3 by January 1, 2014; therefore, removal of the emission limitations for these retired units specified in [[Page 86994]] paragraph (d)(5)(i) would not relax any requirements or have any effect on air quality in the area surrounding FCPP. 4. Revisions to 40 CFR 49.5512(e) Paragraph (e) of 40 CFR 49.5512 generally relates to testing and monitoring requirements that follow in subparagraphs (e)(1)-(e)(8). Under paragraph (e), prior to subparagraph (e)(1), we are proposing to remove specific provisions for particulate matter testing and to move revised provisions for PM to subparagraph (e)(3). The EPA is proposing this revision to improve the clarity of the regulatory requirements. Therefore, this proposed revision, to address testing and monitoring requirements elsewhere, within specific sub-paragraphs in paragraph (e), would not relax any requirements or affect air quality in the surrounding area. We address the specific provisions related to revisions to the PM testing and monitoring provisions in a separate discussion on paragraph (e)(3). In paragraph (e), we are also proposing to remove provisions related to opacity and move revised opacity monitoring requirements to paragraph (e)(6). We are proposing to remove the existing opacity monitoring exemption for periods when the stack is saturated and to remove the presumption that high opacity readings that occur when the baghouse is operating within normal parameters is caused by water vapor and shall not be considered a violation. As outlined in our justification for proposed revisions to paragraph (d)(4), the existing exemptions for opacity monitoring for periods of saturated stacks are inconsistent with the EPA's interpretation of CAA requirements to prohibit emission limitation exemptions and affirmative defenses applicable to excess emissions during malfunctions. The proposed revisions to the opacity standard and monitoring requirements strengthen the FIP and therefore, these changes would not affect air quality in the surrounding area. In paragraph (e)(1), we are proposing to remove the provision specifying a compliance deadline for installing CEMS for SO2 , NOX , and a diluent because the CEMS for those pollutants have already been installed. The EPA is not revising the provisions related to the required operation, maintenance, or certification of the CEMS. Because we are proposing to delete a requirement that merely establishes a compliance date that has already been met, this proposed revision would not relax any requirements or affect air quality in the surrounding area. In paragraph (e)(3), the EPA is proposing to revise the annual PM testing requirements to require the owner or operator to either: Conduct PM testing in accordance with the quarterly testing specifications in the MATS Rule (see Table 5, 40 CFR part 63, subpart UUUUU); to install, calibrate, maintain, and operate a CPMS on each unit in accordance with the MATS Rule (see 40 CFR part 63, subpart UUUUU); or to install, calibrate, maintain, and operate a PM CEMS on each unit, in accordance with the MATS Rule (see 40 CFR part 63, subpart UUUUU). Currently, paragraph (e)(3) requires annual PM testing. We are proposing to align the PM testing requirement in the 2007 FIP with the testing requirements in the MATS Rule, which includes either quarterly testing or continuous monitoring. Therefore, this proposed revision would increase the frequency of PM testing required in the FIP from an annual basis to either a quarterly or a continuous basis. In addition, the testing provisions in the MATS Rule generally refer to the same test methods as those already referenced elsewhere in the FCPP FIP in paragraphs (e) and (i)(1), e.g., 40 CFR part 60 Appendices A-1 through A-3, Methods 1 through 4, and Method 5. Therefore, this proposed revision streamlines testing for PM, does not relax any other requirements, and makes the testing requirements for PM under the FIP consistent with the PM testing requirements in a recent national rulemaking. This proposed revision would not have adverse impacts on air quality in the surrounding area. In paragraph (e)(6), we are proposing to clarify that this opacity monitoring provision applies only to units at FCPP that are subject to the opacity standard at paragraph (d)(4). As discussed elsewhere in this proposed rule, we are proposing that the opacity standard would apply only if the owner or operator does not elect to monitor compliance with the PM limit using PM CEMS. If the opacity standard applies, under paragraph (e)(6) we are proposing three options for determining compliance with the opacity standard. The first option specifies separate compliance demonstrations for the opacity standard under dry and wet conditions. When the stack is dry (unsaturated), we are proposing to continue to require use of the existing COMS. However, during periods of wet (saturated) stack conditions, which are currently infrequent, the condensed water vapor may impede the accuracy of opacity measurements. Therefore, anticipating that saturated stack conditions at FCPP may occur more frequently in the future, we are proposing to require the owner or operator to demonstrate compliance with the opacity standard during saturated stack conditions using visible emission performance testing. We consider the visible emission compliance demonstrations to provide reasonable demonstrations of compliance with the opacity standard during these infrequent occurrences. However, when the stacks at FCPP are lined to eliminate the scrubber bypass and result in consistently saturated stacks, continuous visible emission performance tests may be impractical. Therefore, we are proposing two additional options for determining compliance with the opacity standard. Both options are provided in 40 CFR part 60 subpart Da as alternatives to COMS for units experiencing interference from water vapor.\39\ In paragraph (e)(6)(ii), we are proposing a second option that requires the installation and maintenance of a CPMS, in accordance with the MATS Rule at 40 CFR part 63 subpart UUUUU, combined with periodic visible emission testing in accordance with 40 CFR 60.49Da(a)(3). In paragraph (e)(6)(iii), we are proposing a third option that requires monitoring performance of the existing baghouses using a bag leak detection system in accordance with 40 CFR 60.48Da(o)(4), or an alternative bag leak detection system approved by the EPA, combined with periodic visible emission testing in accordance with 40 CFR 60.49Da(a)(3).\40\ As discussed elsewhere in this notice, the proposed revisions to the opacity standard and monitoring requirements would strengthen the FIP and benefit air quality in the surrounding area because they remove existing exemptions in the FIP and provide reasonable alternatives to address saturated stack conditions in a manner that is consistent with other national rulemakings. --------------------------------------------------------------------------- \39\ See 40 CFR 60.49Da(2)(i) and 60.49Da(a)(4)(ii). \40\ Under 40 CFR 60.13(h)(3)(i), the Administrator may approve alternatives to any monitoring procedures or requirements of part 60. --------------------------------------------------------------------------- Because Units 1, 2, and 3 have permanently ceased operation, we are proposing to delete the testing requirements for those units in paragraph (e)(8). Removal of the testing requirements for these retired units would not relax any requirements or have any effect on air quality in the area surrounding FCPP. 5. Revisions to 40 CFR 49.5512(f) The EPA is proposing revisions to the reporting and recordkeeping requirements to provide additional clarity that all reports and notifications [[Page 86995]] required in paragraph (f), (f)(4), and (f)(4)(ii) must be submitted to the NNEPA and the EPA. Within the recordkeeping and reporting requirements in paragraph (f), we are proposing changes to clarify that any reports that are required to be submitted to the Regional Administrator or the Administrator must be submitted to the Director of NNEPA and to the Air Division Director at Region IX office of the EPA. We are also revising paragraph (f) to require that the Director of the Enforcement Division, in addition to the Director of the Air Division, at the Region IX office of the EPA, be provided reports and notifications. These proposed revisions do not relax any requirements or have any effect on air quality in the area surrounding FCPP. Paragraph (f)(1) requires notification and recordkeeping requirements for the CEMS. The EPA is proposing to add the COMS and visible emission testing to the notification and recordkeeping requirements in this paragraph. These proposed revisions do not relax any requirements and would not adversely affect air quality in the area surrounding FCPP. In paragraph (f)(3), we are proposing to delete the specification related to the frequency of particulate matter testing but are not proposing to modify any provisions related to PM testing reports to the EPA. As discussed elsewhere, we are proposing modifications to the PM testing requirements to align with the MATS Rule, which provides three options for demonstrating compliance with the PM emission limitations: Quarterly stack tests, CPMS, or PM CEMS. Deleting the specification in paragraph (f)(3) that PM testing occurs annually is consistent with the proposed revision to align the PM testing and monitoring requirements for FCPP with those of the MATS Rule. In addition, in paragraphs (f)(4)(i) and (f)(4)(ii), we are proposing to delete the mailing addresses and other details related to reporting requirements, as they are redundant to the provisions in paragraph (f). All reports and notifications under paragraph (f) must be submitted to the NNEPA and the EPA, and we are proposing to clarify under paragraph (f) that all references to the Regional Administrator in that paragraph mean the Directors of the NNEPA and two divisions within the EPA Region IX office. Paragraph (f)(4) repeats addresses and other details already stated in paragraph (f). The EPA is proposing to delete these redundant provisions in paragraph (f)(4). We anticipate this revision would improve regulatory clarity and would have no impact on air quality in the surrounding area. Consistent with the proposed revisions to the opacity standard and COMS requirement in paragraphs (d) and (e), we are proposing to delete references to saturated stack conditions in paragraphs (f)(4)(i) and (f)(4)(i)(H). In paragraph (f)(4)(i)(G), we are also proposing to require the owner or operator to report opacity exceedances determined from the visible emission performance tests. As discussed elsewhere in this notice, because provisions in the existing FCPP FIP exempt the units from the opacity limit during periods where the stacks were saturated, the removal of the exemption represents a strengthening of the FIP and would not relax other requirements in the FCPP FIP. 6. Revisions to 40 CFR 49.5512(h) The EPA is proposing to delete the startup and shutdown exemptions for the opacity and PM emission limitations at paragraph (h)(2) and to delete the provisions related to an affirmative defense for malfunctions in paragraph (h)(3). As discussed previously, exemptions from emission limitations and provisions that allow an affirmative defense are inconsistent with CAA requirements. Using the same rationale we provided elsewhere in this notice, for the proposed revisions to 40 CFR 52.5512(c) and (d), the EPA is proposing to delete the provisions at paragraph (h)(2) that provide an exemption from emission limitations during periods of startup and shutdown and also to delete the provisions in the paragraph (h)(3) that provide an affirmative defense for malfunctions at FCPP. The proposed removal of these provisions strengthens the FIP and does not relax any other requirements in the FIP. Therefore, the removal of these revisions would not adversely affect air quality in the surrounding area. 7. Revisions to 40 CFR 49.5512(i) Under paragraph (i)(1), promulgated in the 2012 FIP, the EPA is proposing to delete the existing provisions related to annual PM testing and add a provision that PM testing shall be performed in accordance with paragraph (e)(3), which requires quarterly PM testing, or installation, calibration, and operation of CPMS, or PM CEMS, in accordance with the MATS Rule. This proposed revision would increase the frequency of PM testing from an annual basis to either a quarterly or continuous basis. The testing provisions in the MATS Rule generally refer to the same test methods already referenced in the FIP in paragraphs (e) and (i)(1), e.g., 40 CFR part 60 Appendices A-1 through A-3, Methods 1 through 4, and Method 5. This proposed revision would not relax any requirements and would make the testing requirements for PM under the FIP consistent with the PM testing requirements in recent national rulemakings. Therefore, this revision would not have adverse impacts on air quality in the surrounding area. In addition, under paragraph (i)(2)(iii) of the 2012 FIP, we are proposing to correct a typographical error in a citation. Paragraph (i)(2)(iii) provides the schedule for the installation of add-on post- combustion NOX controls and refers to interim emission limitations for NOX at paragraph (i)(2)(ii)(A). However, the interim emission limitations are found in paragraph (i)(2)(ii), and subparagraph (A) to paragraph (i)(2)(ii) does not exist. Although the interim limits under paragraph (i)(2)(ii) do not apply because the owner or operator elected to implement paragraph (i)(3) in lieu of paragraph (i)(2) for NOX , the EPA is proposing to correct this error in order to improve regulatory clarity. This proposed revision would have no effect on air quality in the surrounding area. 8. Addition of 40 CFR 49.5513(k) The EPA is proposing to add paragraph (k) to include provisions required for compliance with the Consent Decree. The EPA is not revisiting or opening for comment any of the specific requirements of the Consent Decree and is requesting comment only on whether the EPA has incorporated all appropriate requirements from the Consent Decree into the FIP. Generally, the Consent Decree established emission limitations and other requirements to reduce emissions of SO2 , NOX and PM. The Consent Decree requires the owner or operator to modify the existing ductwork and stacks for Units 4 and 5 to accommodate a wet stack in order to eliminate the need to bypass flue gas around the scrubbers and to achieve and maintain an SO2 removal efficiency of at least 95 percent, which is more stringent than the requirement to achieve an 88 percent removal efficiency in paragraph (d)(1)(i). The Consent Decree also established an emission limitation for NOX of 0.080 lb/MMBtu, which is more stringent than the NOX limit of 0.098 lb/MMBtu in 40 CFR 49.5512(i)(3) from the 2012 FIP. Finally, the Consent Decree established a PM emission limitation of 0.0150 lb/MMBtu for Units 4 and 5, which is more stringent than the PM limit of 0.015 lb/MMBtu that was applied to those units in the 2012 FIP. Because the Consent Decree set more [[Page 86996]] stringent emission limitations, the proposed revision to incorporate the provisions of the Consent Decree into the FIP for FCPP strengthens the FIP and would not relax any existing requirements. In this action, the EPA is merely proposing to incorporate the existing Consent Decree requirements into the FIP for FCPP and is requesting comment only on whether the EPA has incorporated all appropriate requirements from the Consent Decree into the FIP. The Consent Decree is anticipated to benefit air quality, and the proposed inclusion of the Consent Decree requirements in the FIP would make those requirements continue to be federally enforceable after the Consent Decree is terminated. C. Compliance Schedule The EPA proposes that the requirements contained in this proposal will become enforceable on the effective date following final promulgation of this FIP revision unless otherwise provided in a specific provision of the FIP. IV. Proposed Action and Solicitation of Comments As described above, the EPA proposes revisions to the FCPP FIP for several reasons: (1) To make certain provisions in the FIP consistent with national rulemakings and other actions since 2012; (2) to update the FIP to reflect recent operating changes; and (3) to add new provisions to the FIP to include the requirements of the Consent Decree. The EPA solicits comments on the limited revisions of the FCPP FIP that we are proposing in this rulemaking. We are also soliciting comment on whether the EPA has accurately incorporated the requirements from the Consent Decree into paragraph (k) of the FIP. We are not accepting comment on any provisions of the FCPP FIP that we are not proposing to revise, and we are not accepting comment on the specific requirements of the Consent Decree. Accordingly, please limit your comments to those specific provisions recited above that we are proposing to revise in today's action. V. Environmental Justice Considerations The Four Corners Power Plant is located on the reservations lands of the Navajo Nation, and the EPA recognizes there is significant community interest in the emissions and environmental effects of this facility. As discussed elsewhere in this document, the proposed revisions to the FCPP FIP would: Strengthen the FIP by removing emission limitation exemptions for periods of startup, shutdown, and saturated stacks; remove an affirmative defense applicable to excess emissions during malfunctions; and codify more stringent emission limitations for SO2 , NOX , and PM from a Consent Decree dated August 17, 2015. Additional revisions to the FCPP FIP proposed in this notice, including to streamline certain testing requirements to be consistent with national rulemakings promulgated since 2008 and to remove requirements for units that have permanently ceased operation, would not relax any condition in the FCPP FIP. Therefore, the EPA considers this proposed action to be beneficial for human and environmental health, and to have no potential disproportionately high and adverse effects on minority, low-income, or indigenous populations. VI. Statutory and Executive Order Reviews A. Executive Order 12866: Regulatory Planning and Review and Executive Order 13563: Improving Regulation and Regulatory Review This action is not a significant regulatory action and was therefore not submitted to the Office of Management and Budget (OMB) for review. B. Paperwork Reduction Act (PRA) This action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. This rule applies to only one facility. Therefore, its recordkeeping and reporting provisions do not constitute a ``collection of information'' as defined under 44 U.S.C. 3502(3) and 5 CFR 1320.3(c). C. Regulatory Flexibility Act (RFA) I certify that this proposed action will not have a significant economic impact on a substantial number of small entities. This action will not impose any requirements on small entities. Firms primarily engaged in the generation, transmission, and/or distribution of electric energy for sale are small if, including affiliates, the total electric output for the preceding fiscal year did not exceed four million megawatt-hours. Each of the owners of the facility (i.e., Arizona Public Service, Salt River Project, Tucson Electric Power, and El Paso Electric) affected by this rule exceed this threshold. D. Unfunded Mandates Reform Act (UMRA) This action does not contain an unfunded mandate of $100 million or more as described in UMRA, 2 U.S.C. 1531-1538, and does not significantly or uniquely affect small governments. E. Executive Order 13132: Federalism This action does not have federalism implications. It will not have substantial direct effects on the states, on the relationship between the national government and the states, or on the distribution of power and responsibilities among the various levels of government. F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments This action does not have tribal implications, as specified in Executive Order 13175. Although this proposed action affects a facility located in Indian country, the proposed limited revisions to existing provisions in the FIP for FCPP, and the incorporation of provisions into the FIP from a Consent Decree, which has already undergone public review and was the subject of tribal consultation, will not have substantial direct effects on any Indian tribes, on the relationship between the federal government and Indian tribes, or on the distribution of power and responsibilities between the federal government and Indian tribes. Thus, Executive Order 13175 does not apply to this action. However, we note that we have engaged in numerous discussions with the NNEPA during the development of this proposed rule and continue to invite consultation on this proposed action. G. Executive Order 13045: Protection of Children From Environmental Health Risks and Safety Risks EPA interprets EO 13045 as applying only to those regulatory actions that concern health or safety risks that EPA has reason to believe may disproportionately affect children, per the definition of ``covered regulatory action'' in section 2-202 of the Executive Order. This action is not subject to Executive Order 13045 because it does not concern an environmental health risk or safety risk. H. Executive Order 13211: Actions Concerning Regulations That Significantly Affect Energy Supply, Distribution, or Use This action is not subject to Executive Order 13211 because it is not a significant regulatory action under Executive Order 12866. I. National Technology Transfer and Advancement Act This action involves technical standards. The technical standards in this action are based on the technical standards used in other rulemakings promulgated by the EPA. We refer to the [[Page 86997]] discussion of the technical standards and voluntary consensus standards in the final rule for 40 CFR part 60 subpart Da and 40 CFR part 63 subpart UUUUU at 77 FR 9304 at 9441 (February 16, 2012). J. Executive Order 12898: Federal Actions To Address Environmental Justice in Minority Populations and Low-Income Populations The EPA believes the human health or environmental risk addressed by this action will not have potential disproportionately high and adverse human health or environmental effects on minority, low-income or indigenous populations. If this rule is finalized as proposed, we expect that the limited revisions to the FIP will strengthen requirements for periods of startup, shutdown, and malfunction and will not relax any other existing requirements. Additional revisions related to streamlining of PM testing and providing options for PM and opacity testing that are in accordance with other rulemakings from the EPA will not affect air quality in the area surrounding FCPP.

Such report shall: (A) Provide the identity of the non-profit third-party recipient(s) of the SO2 [[Page 87002]] Allowances and a listing of the serial numbers of the transferred SO2 Allowances; and (B) Include a certification by the third-party recipient(s) certifying under the penalty of law that the recipient(s) will not sell, trade, or otherwise exchange any of the allowances and will not use any of the SO2 Allowances to meet any obligation imposed by any environmental law. The certification must also include a statement that the recipient understands that there are significant penalties for submitting false, inaccurate or incomplete information to the United States. (C) No later than the third semi-annual report due after the transfer of any SO2 Allowances, the owner or operator shall include a statement that the third-party recipient(s) Surrendered the SO2 Allowances for permanent Surrender to EPA in accordance with the provisions of paragraph (k)(4)(ix) within one (1) year after the owner or operator transferred the SO2 Allowances to them. The owner or operator shall not have complied with the SO2 Allowance Surrender requirements of subparagraph (k)(4)(viii) until all third-party recipient(s) shall have actually Surrendered the transferred SO2 Allowances to EPA. (viii) For all SO2 Allowances Surrendered to EPA, the owner or operator or the third-party recipient(s) (as the case may be) shall first submit an SO2 Allowance transfer request form to the EPA Office of Air and Radiation's Clean Air Markets Division directing the transfer of such SO2 Allowances to the EPA Enforcement Surrender Account or to any other EPA account that EPA may direct in writing. Such SO2 Allowance transfer requests may be made in an electronic manner using the EPA's Clean Air Markets Division Business System or similar system provided by EPA. As part of submitting these transfer requests, the owner or operator or the third- party recipient(s) shall irrevocably authorize the transfer of these SO2 Allowances and identify--by name of account and any applicable serial or other identification numbers or station names--the source and location of the SO2 Allowances being Surrendered. (5) PM Emission Reduction Requirements. (i) The owner or operator shall operate each FCPP Unit in a manner consistent with good air pollution control practice for minimizing PM emissions, as set forth in paragraph (g). In addition, with respect to FCPP Units 4 and 5, the owner or operator shall, at a minimum, to the extent practicable: (A) Operate each compartment of the Baghouse for each Unit (except the compartment provided as a spare compartment under the design of the baghouse), regardless of whether those actions are needed to comply with opacity limits; (B) Repair any failed Baghouse compartment at the next planned Unit outage (or unplanned outage of sufficient length); (C) Maintain and replace bags on each Baghouse as needed to achieve the required collection efficiency; (D) Inspect for and repair during the next planned Unit outage (or unplanned outage of sufficient length) any openings in Baghouse casings, ductwork, and expansion joints to minimize air leakage; and (E) Ensure that a bag leak detection program is developed and implemented to detect leaks and promptly repair any identified leaks. (ii) The owner or operator shall Continuously Operate a Baghouse at FCPP Unit 4 and Unit 5 so as to achieve and maintain a filterable PM Emission Rate no greater than 0.0150 lb/MMBtu. (iii) Once in each calendar year, the owner or operator shall conduct stack tests for PM at FCPP Units 4 and 5. Alternatively, following the installation and operation of PM CEMS as required by paragraph (k)(6), the owner or operator may seek written approval to forego stack testing and instead demonstrate continuous compliance with an applicable filterable PM Emission Rate using CEMS on a 24-hour rolling average basis. (iv) Unless EPA approves a request to demonstrate continuous compliance using CEMS under paragraph (k)(5)(iii) to determine compliance with the PM Emission Rate established in subparagraph (k)(5)(ii), the owner or operator shall use the reference methods and procedures (filterable portion only) specified in 40 CFR part 60, App. A-3, Method 5, Method 5 as described in subpart UUUUU, Table 5, or App. A-6, Method 17 (provided that Method 17 shall only be used for stack tests conducted prior to conversion of an FCPP Unit to a Wet Stack), or alternative stack tests or methods that are requested by the owner or operator and approved by EPA. Each test shall consist of three separate runs performed under representative operating conditions not including periods of startup, shutdown, or Malfunction. The sampling time for each run shall be at least 120 minutes and the volume of each run shall be at least 1.70 dry standard cubic meters (60 dry standard cubic feet). The owner or operator shall calculate the PM Emission Rate from the stack test results in accordance with 40 CFR 60.8(f). The results of each PM stack test shall be submitted to EPA and NNEPA within 60 Days of completion of each test. (v) Once each calendar year, the owner or operator shall conduct a PM stack test for condensable PM at FCPP Units 4 and 5, using the reference methods and procedures set forth at 40 CFR part 51, Appendix M, Method 202 and as set forth in paragraph (vi). This test shall be conducted under as similar operating conditions and as close in time as reasonably possible as the test for filterable PM in paragraph (k)(5)(iv). Each test shall consist of three separate runs performed under representative operating conditions not including periods of startup, shutdown, or Malfunction. The sampling time for each run shall be at least 120 minutes and the volume of each run shall be at least 1.70 dry standard cubic meters (60 dry standard cubic feet). The owner or operator shall calculate the number of pounds of condensable PM emitted in lb/MMBtu of heat input from the stack test results in accordance with 40 CFR 60.8(f). The results of the PM stack test conducted pursuant to this paragraph shall not be used for the purpose of determining compliance with the PM Emission Rates required by paragraph (k). The results of each PM stack test shall be submitted to EPA within sixty (60) Days of completion of each test. If EPA approves a request to demonstrate continuous compliance with an applicable PM Emission Rate at a Unit using PM CEMS under paragraph (k)(5)(iii), annual stack testing for condensable PM using the reference methods and procedures set forth at 40 CFR part 51, Appendix M, Method 202 is not required for that Unit. (6) PM CEMS. (i) The owner or operator shall install, correlate, maintain, and operate a PM CEMS for FCPP Unit 4 and FCPP Unit 5 as specified below. The PM CEMS shall comprise a continuous-particle mass monitor measuring particulate matter concentration, directly or indirectly, on an hourly average basis and a diluent monitor used to convert the concentration to units expressed in lb/MMBtu. The PM CEMS installed at each Unit must be appropriate for the anticipated stack conditions and capable of measuring PM concentrations on an hourly average basis. Each PM CEMS shall complete a minimum of one cycle of operations (sampling, analyzing and data recording) for each successive 15-minute period. The owner or operator shall maintain, in an electronic database, the hourly-average emission values of all PM CEMS in lb/MMBtu. Except for periods of monitor [[Page 87003]] malfunction, maintenance, or repair, the owner or operator shall continuously operate the PM CEMS at all times when the Unit it serves is operating. (ii) By no later than February 16, 2017, the owner or operator shall ensure that the PM CEMS are installed, correlated, maintained and operated at FCPP Units 4 and 5. (iii) The owner or operator shall ensure that performance specification tests on the PM CEMS are conducted and shall ensure compliance with the PM CEMS installation plan and QA/QC protocol submitted to and approved by EPA. The PM CEMS shall be operated in accordance with the approved plan and QA/QC protocol. (iv) The data recorded by the PM CEMS during Unit operation, expressed in lb/MMBtu on a 3-hour, 24-hour, and 30-Day rolling average basis, shall be included in the semiannual report submitted to EPA in electronic format (Microsoft Excel-compatible). (v) Notwithstanding any other provision of paragraph (k), exceedances of the PM Emission Rate that occur as a result of detuning emission controls as required to achieve the high-level PM test runs during the correlation testing shall not be considered a violation of the requirements of this section provided that the owner or operator made best efforts to keep the high-level PM test runs during such correlation testing below the applicable PM Emission Rate. (vi) Stack testing conducted pursuant to paragraph (k)(5)(iv) shall be the compliance method for the PM Emission Rates established by paragraph (k)(5), unless EPA approves a request under paragraph (k)(5)(iii), in which case PM CEMS shall be used to demonstrate continuous compliance with an applicable PM Emission Rate on a 24-hour rolling average basis. Data from PM CEMS shall be used, at a minimum, to monitor progress in reducing PM emissions on a continuous basis. (7) Reporting. The owner or operator shall submit all notifications, petitions, and reports under paragraph (k), unless otherwise specified, to EPA and NNEPA in accordance with paragraph (f).
