Approval and Promulgation of Air Quality Implementation Plans; Colorado; Revisions to Common Provisions and Regulation Number 3; Correction

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

The Environmental Protection Agency (EPA) is proposing approval of State Implementation Plan (SIP) revisions submitted by the State of Colorado on March 31, 2010, May 16, 2012, and May 13, 2013. The revisions are to Colorado Air Quality Control Commission (Commission) Regulation Number 3, Parts A, B, and D and Common Provisions Regulation. The revisions include administrative changes to permitting requirements for stationary sources, updates to the fine particulate matter less than 2.5 microns in diameter (PM_2.5) implementation rules related to the federal New Source Review (NSR) Program, changes to address previous revisions to Air Pollutant Emission Notice (APEN) regulations that EPA disapproved or provided comments on, revisions to definitions, and minor editorial changes. Also in this action, EPA is proposing to correct a final rule pertaining to Colorado's SIP published on April 24, 2014. In our April 24, 2014 action, regulatory text and corresponding “incorporation by reference” (IBR) materials were inadvertently excluded for (1) greenhouse gas permitting revisions to the Common Provisions Regulation, and (2) minor editorial changes to the Common Provisions Regulation and Parts A, B, and D of Regulation Number 3 (adopted October 10, 2010). This action is being taken under section 110 of the Clean Air Act (CAA).

DATES:

Written comments must be received on or before October 14, 2015.

II. Background

A. On March 31, 2010 the State of Colorado submitted a SIP revision containing amendments to the Common Provisions Regulation sections I.A., I.B., I.C., I.D., I.E., I.F., I.G., II.B., II.C., II.E., II.H. and II.J. The amendments update the definition of “negligibly reactive volatile organic compound,” add clarification to the definition of “volatile organic compound,” and make minor editorial changes. The Commission adopted the amendments on December 17, 2009 (effective January 30, 2010).

B. On May 16, 2012 the State submitted a SIP revision containing amendments to Regulation Number 3, Parts A, B and D. The amendments modify the permitting requirements for stationary sources in Colorado by: (1) Incorporating into state regulations changes to the federal NSR Program related to the PM_2.5 National Ambient Air Quality Standards (NAAQS); (2) revising state regulations to address past rule revisions that were disapproved or commented on by EPA; (3) deferring permitting requirements for biogenic sources of carbon dioxide emissions to ensure consistency with federal greenhouse gas permitting requirements; and (4) making miscellaneous revisions and minor editorial changes. The Commission adopted the amendments on October 20, 2011 (effective December 15, 2011).

C. On May 13, 2013 Colorado submitted a SIP revision containing amendments to Regulation Number 3, Parts A, B and D. The amendments make administrative revisions to the permitting requirements for stationary sources in Colorado and make minor editorial changes. The Commission adopted the amendments on December 20, 2012 (effective February 15, 2013).

D. On April 24, 2014 EPA published a final rule (79 FR 22772) in the Federal Register approving Colorado's May 25, 2011 SIP revisions to the Common Provisions Regulation related to greenhouse gas and minor editorial changes to the Common Provisions Regulation and Regulation Number 3 Parts A, B and D (adopted October 10, 2010). This action includes regulatory text and IBR material intended to be a part of EPA's April 24, 2014 final rule but inadvertently excluded.

III. EPA's Review of the State of Colorado's March 31, 2010; May 16, 2012; and May 13, 2013 Submittals, and Regulatory Text/IBR Correction

We evaluated Colorado's March 31, 2010, May 16, 2012 and May 13, 2013 submittals regarding revisions to the State's Common Provisions Regulation and Regulation Number 3, Parts A, B and D. We propose to approve some of the revisions and not act on others.

A. March 31, 2010 SIP Submittal

The State's March 31, 2010 SIP submittal contained amendments to the Common Provisions Regulation and includes the following types of amendments to the State's air quality rules: Adding compounds to the definition of “negligibly reactive volatile compounds” (NRVOC) and clarifying NRVOC and volatile organic compound (VOC) testing methodologies within the definition of “volatile organic compound.” In addition, the State subsequently requested a revision to the definition of “incinerator.” The revisions also make minor editorial changes.

EPA's policy is that compounds of carbon with a negligible level of reactivity need not be regulated to reduce ozone (42 FR 35314). EPA determines whether a given carbon compound has “negligible” reactivity by comparing the compound's reactivity to the reactivity of ethane. EPA lists these compounds in its regulations at 40 CFR 51.100(s), and excludes them from the definition of a “VOC.” The chemicals on this list are often called “negligibly reactive.” EPA may periodically revise the list of negligibly reactive volatile compounds or NRVOCs to add or delete compounds from the list. In its March 31, 2010 submission, the State adds the following compounds: “(1)1, 1, 1, 2, 2, 3, 4, 5, 5, 5, -decafluoro-3-methoxy-4-trifluoromethyl-pentane” ; “Propylene carbonate”; and “Dimethyl carbonate,” as well as the common names or chemical structure: “n-C₃ F₇ OCH₃, HFE-7000”; “HFE-7500”; “HFC 227ea”; “HCOOCH₃”; and “HFE-7300” to the list of NRVOCs. Subsequent to the March 31, 2010 submission, the State also requested to add “1, 1, 1, 2, 2, 3, 3, -heptafluoro-3-methoxy-propane”; “3-ethoxy-1, 1, 1, 2, 3, 4, 4, 5, 5, 6, 6, 6-dodecafluoro-2(trifluoromethyl)hexane”; “1, 1, 1, 2, 3, 3, 3-heptafluoropropane”; and “Methyl formate” to the list of NRVOCs in section I.G. EPA is proposing to approve these additions to the State's Common Provisions Regulation list of NRVOCs per our earlier actions (72 FR 2193; 74 FR 3437; 78 FR 9823) updating EPA's listing of organic compounds determined to have negligible photochemical reactivity at 40 CFR 51.100(s)(1).

The March 31, 2010 revision to the Common Provisions Regulation also revises the definition of “VOC” to include test methods specified in the State's SIP, a Title V Permit, 40 CFR part 51, subpart I or appendix S, and 40 CFR part 52. In accordance with 40 CFR 51.100(s)(2) and (4), EPA proposes to approve revisions to the definition of “VOC” in section I.G. of the Common Provisions Regulation.

In addition to modifying the definitions of NRVOC and VOC, the State also subsequently requested revisions to the definition of “incinerator” in section I.G. The revisions exclude from the definition of “incinerator” devices commonly called Air Curtain Destructors used to burn 100% wood waste, clean lumber, or yard waste generated as a result of projects to reduce the risk of wildfire and not operated at a commercial or industrial facility. The revisions also state that any air curtain destructor (also called air curtain incinerator in the federal rule) subject to 40 CFR part 60 incinerator requirements are also considered incinerators under the State's revised Common Provisions Regulation definition of “incinerator” per EPA's final rule (70 FR 74870) for New Source Performance Standards (NSPS) for new and existing “other” solid waste incineration units. We propose to approve these revisions.

The March 2010 submittal also makes minor editorial revisions to the Common Provisions Regulation. We are proposing to approve the minor editorial revisions in sections I.A., I.B., I.C., I.D., I.E., I.F., I.G., II.B., II.C., II.E.2. and II.H as shown in Table 1. We are not acting on the minor editorial revisions in II.J. as they are either already in the approved SIP or in sections that EPA previously disapproved (Table 2). Also, we note that the March 31, 2010 submittal is missing a quotation mark in Section I.B. and contains the incorrect abbreviation for “microgram” in Section I.F. The State is aware of these errors and will make the necessary corrections in a future submittal.

Finally, the March 31, 2010 submission contains text not currently in the Common Provisions section of the SIP yet also not identified by the State as a revision. This text includes the addition of “Tertiary Butyl Acetate (2-Butanone)” to the list of NRVOCs in section I.G. as well as the last sentence in the definition of “VOC” regarding tertiary butyl acetate as a VOC for the purposes of photochemical dispersion monitoring. On November 29, 2004 (69 FR 69298), EPA revised its definition of VOC to exclude tertiary butyl acetate for purposes of VOC emissions limitations or VOC content requirements; however, tertiary butyl acetate continues to be a VOC for purposes of all recordkeeping, emissions reporting, and inventory purposes as reflected in 40 CFR 51.100(s)(1) and (s)(5). Therefore, EPA is not including these State additions with our proposed approval of IBR material.

B. May 16, 2012 SIP Submittal

The State's May 16, 2012 SIP submittal includes the following types of amendments to Regulation Number 3, Parts A, B and D: Revisions to State permitting requirements for stationary sources to incorporate changes to the federal NSR Program related to PM_2.5; revisions to address past rule revisions that were disapproved or commented on by EPA; and deferral of the permitting requirements for biogenic sources of carbon dioxide emissions to ensure consistency with federal greenhouse gas permitting requirements. The revisions also make several miscellaneous changes along with minor editorial changes.

The May 16, 2012 submittal incorporates into Regulation Number 3, Parts A, B and D changes to the federal NSR Program related to the PM_2.5 NAAQS. Specifically, the State revised the definition of “criteria pollutants” to address PM_2.5 precursors in Part A (I.B.17.) and revised the definition of “significant” to address PM_2.5 in Part D (II.A.42.). We are proposing to approve both of these revisions to definitions to address PM_2.5. In addition, the State incorporated portions of 40 CFR 51.165(a)(9)(i)-(iv) into the State's Requirements Applicable to Nonattainment Areas for Major Sources in Part D of Regulation Number 3 (V.A.3.). This section describes the emissions offsets and emissions offset ratios required prior to the date of commencement of operations. We are proposing to approve this revision. We are also proposing to approve the State's revision to the Table of Significance Levels for nonattainment areas in section VI.D.2. of Part D to address PM_2.5. Finally, the State added PM_2.5 increments to their ambient air increments in section X.A.1. of Part D and added PM_2.5 increments to their Class I variances maximum allowable increases in section XIII.D. of Part D. These revisions align with 40 CFR 52.21(b)(58)(c) and 52.21(p)(5), respectively, and we therefore propose to approve these revisions.

The State also revised the definition of “Subject to Regulation” in Part A of Regulation Number 3 in their May 16, 2012 submittal. In section I.B.44.b.(i) the State added language to instruct how to compute greenhouse gas emissions to exclude carbon dioxide emissions resulting from the combustion or decomposition of non-fossilized and biodegradable organic material originating from plants, animals, or micro-organisms. This addition is consistent with EPA's biogenic deferral regulation found at 40 CFR 52.21(b)(49)(a)(ii); therefore, we are proposing to approve the revision.

The May 16, 2012 submission also makes revisions to Regulation Number 3, Part B based on EPA's comments on previous actions (76 FR 6331; 79 FR 8632). These revisions include reverting back to previously approved SIP exemption language for stationary internal combustion engines that have uncontrolled actual emissions of less than five tons per year for construction permit requirements (II.D.1.c.) and clarifying exemptions associated with oil and gas produced wastewater impoundments (II.D.1.m). We are proposing to approve these revisions.

Within section VI.B.3. of Part D of the May 16, 2012 submittal, the State revised the PM₁₀ surrogate policy for PM_2.5 based on EPA's previous conclusions that PM_2.5 implementation issues had been resolved to a degree sufficient for all federal Prevention of Significant Deterioration (PSD) permit reviews to begin direct PM_2.5 based assessments as of July 15, 2008. In a letter dated January 13, 2011 the State clarified their position on the use of PM₁₀ as a surrogate for PM_2.5 “. . . (CDPHE) now commits to implement PM_2.5 standards consistent with EPA's latest interpretation of federal case law relevant to the use of the PM₁₀ Surrogate Policy . . .” We are proposing to approve this revision, and in doing so, note that as announced in our May 2008 rulemaking to implement preconstruction review provisions for the 1997 PM_2.5 NAAQS in both attainment and nonattainment areas (73 FR 28321), the 1997 PM₁₀ Surrogate Policy ended on May 16, 2011 and can no longer be used for any pending or future State PSD permits.

Also regarding the May 16, 2012 submittal, we are proposing to take no action on several of the State's revisions related to PM_2.5 implementation in Part D of Regulation Number 3, including section II.A.26.d. describing net emissions increases for PM_2.5, the introductory paragraph of VI.A.2. and VI.A.2.c. that provide impact levels for PM_2.5, and VI.B.3.a.(iii) PM_2.5 monitoring exemption of 4 micrograms/cubic meter over a 24-hour average. We are proposing to not act on these revisions in part due to the January 22, 2013 United States Court of Appeals for the District of Columbia Circuit vacatur of the significant impact levels for PM_2.5 for attainment areas. Since we are proposing to not take action on the PM_2.5 monitoring exemption level found at VI.B.3.a.(iii), we also propose to not take action on VI.B.3.d. In absence of a revision to include a PM_2.5 monitoring exemption level in VI.B.3.a.(iii), PM_2.5 would be removed from the list of pollutants with monitoring exemption levels contained in VI.B.3.a., therefore exempting PM_2.5 from monitoring levels completely if we approved VI.B.3.d.

We are also proposing to take no action on several revisions contained in the May 16, 2012 submittal to Definitions in Part D of Regulation Number 3 to address PM_2.5 in the Baseline Area (II.A.5.a.), Major Source Baseline Date (II.A.23.), Minor Source Baseline Date (II.A.25.) and Regulated NSR Pollutant (II.A.38.) definitions because we already approved these revisions in our September 23, 2013 (78 FR 58186) action. In section II.A.23.c. of Part D, the State also revised the major source baseline date for PM_2.5 to October 20, 2011. This date is incorrect; the correct major source baseline date for PM_2.5 is October 20, 2010. In the May 13, 2013 submittal, also part of this action, the State revises the date back to October 20, 2010. The May 13, 2013 submittal supersedes the May 16, 2012 submittal; however, since the current approved SIP already contains the correct date, we are proposing to take no action on either revision.

Additionally, the May 16, 2012 submission addresses EPA's final action on October 3, 2011 (76 FR 61054) partially approving and partially disapproving Colorado's SIP revisions in Regulation Number 3, Part A to Air Pollutant Emission Notice (APEN) and permitting exemptions submitted to EPA in September 1997, June 2003, July 2005, August 2006, and August 2007. In the October 3, 2011 action, EPA partially disapproved APEN exemptions for open burning, mobile sources, stationary internal combustion engines, emergency generators, deaerator/vacuum pump exhaust, and air curtain destructors. In today's action, we are proposing to approve revisions to the open burning APEN requirements (II.D.1.q.) in Regulation Number 3, Part A changing the reference regulation from “9,” which is not part of Colorado's SIP, to “1,” which is part of Colorado's SIP and clarifying the mobile source APEN (II.D.1.ppp.). Additionally, we are proposing to approve revisions made to the surface water impoundment APEN exemption (II.D.1.uuu.) to include gas production wastewater in addition to oil production wastewater. We are proposing no action on the State's removal of APENs related to stationary internal combustion engines (II.D.1.sss.), emergency power generators (II.D.1.ttt.), deaerator/vacuum pump exhaust (II.D.1.xxx.), and air curtain destructors (II.D.1.ffff.) as these provisions were not approved into the SIP. Finally, we are proposing no action on revisions to identify sections I.B.31.c, and I.B.31.d. as “State-only Requirements” since these are also not part of the SIP.

Finally, the May 16, 2012 submission contains miscellaneous revisions to Parts A, B and D of Regulation Number 3. In Part A, the State clarified the significance level for VOC and NO_X for APEN reporting purposes (II.C.2.b.(ii)). In Part B, section III.G.1., the State changed the timing an applicant must provide notice to the State upon commencement of operation of a source from 30 days prior to startup to 15 days following startup. This revision aligns with 40 CFR 60.7(a)(3) Standards of Performance for New Stationary Sources, Notification and Record Keeping. In Part D, revisions include a correction to move the creditable emissions documentation from II.A.26.d. to II.A.26.c.(iii), remove “total suspended particulate matter” and add NO_X as a precursor to ozone for consistency with federal significant monitoring concentrations requirements in VI.B.3.a.(iii) and VI.B.3.c., respectively. We propose to approve these revisions in addition to minor editorial changes found throughout Parts A, B and D of Regulation Number 3 with exceptions noted in Table 2 because the revisions the State is requesting are already in the SIP.

C. May 13, 2013 SIP Submittal

The State's May 13, 2013 SIP submittal contains amendments to Regulation Number 3 Parts A, B and D and includes administrative revisions to permitting requirements for stationary sources in Colorado and minor editorial changes. The State also updated where materials incorporated by reference are available for public inspection by adding an online web address and deleting reference to the State Publications Depository and Distribution Center in section I.A.

Revisions to section VI.B.5. in Part A of the May 13, 2013 submittal allow the State to issue construction permits prior to receipt of permit processing fees and provide for the option to revoke the permit or assess late fees if such fees are not paid within 90 days of the written request for fees. The purpose of the revisions are to allow applicants to commence construction during the invoicing and payment process; the revisions will not negatively impact permit applicants who pay their permit processing fees on time. A revision to section III.C.1.a. in Part B of the May 13, 2013 submittal clarifies the inclusion of sources in attainment/maintenance areas in the determination of sources subject to public comment. Finally, revisions to Part D of the May 13, 2013 submittal include deleting language EPA previously disapproved (79 FR 8632) in the introductory text for Major Modifications in section II.A.22. and Representative Actual Annual Emissions sections II.A.40.5 and II.A.40.5(a) as well as deleting the associated II.A.40.5(b).

EPA is proposing to approve the revisions in the May 13, 2013 submittal to Parts A, B and D of Regulation Number 3 as well as the minor editorial changes contained throughout, except for sections II.A.22., II.A.40.5 (introductory paragraph), and II.A.40.5(a) in Part D because these are not in the current SIP and the other exceptions noted in Table 2. We are not acting on some of the provisions as listed in Table 2, because they are State-only provisions or because they are not applicable to the current SIP.

Proposed Correction

In our final rule published in the Federal Register on April 24, 2014 (79 FR 22772) we inadvertently did not include regulatory text and corresponding IBR materials for our approvals to (1) greenhouse gas permitting revisions to Common Provisions Regulation, and (2) minor editorial changes to the Common Provisions Regulation and Parts A, B and D of Regulation Number 3 (adopted October 10, 2010). EPA is proposing to correct this error with today's action. The IBR material for our April 24, 2014 action is contained within this docket.

IV. What action is EPA taking?

For the reasons expressed above, EPA is proposing to approve revisions to sections I.A., I.B., I.C., I.D., I.E., I.F., I.G., II.B., II.C., II.E.2. and II.H of the State's Common Provisions Regulation from the March 31, 2010 submittal as shown in Table 1 below. We also propose to approve revisions to Parts A, B and D of the State's Regulation Number 3 from the May 16, 2012 and May 13, 2013 submittals (Table 1), except for those revisions we are not taking action on as represented in Table 2 below. Finally, EPA proposes to correct regulatory text and IBR published in the Federal Register on April 24, 2014 (79 FR 22772).

A comprehensive summary of the revisions in Colorado's Common Provisions Regulation and Regulation Number 3 Parts A, B and D organized by EPA's proposed rule action, reason for proposed “no action” and submittal date are provided in Table 1 and Table 2 below.

V. Incorporation by Reference

In this rulemaking, the EPA is proposing to include in a final EPA rule regulatory text that includes incorporation by reference. In accordance with requirements of 1 CFR 51.5, the EPA is proposing to incorporate by reference Colorado Air Quality Control Commission regulations discussed in section III, EPA's Review of the State of Colorado's March 31, 2010; May 16, 2012; and May 13, 2013 Submittals, and Regulatory Text/IBR Correction of this preamble. The EPA has made, and will continue to make, these documents generally available electronically through www.regulations.gov and/or in hard copy at the appropriate EPA office (see the ADDRESSES section of this preamble for more information).

VI. Statutory and Executive Orders Review

Under the CAA, the Administrator is required to approve a SIP submission that complies with the provisions of the Act and applicable federal regulations (42 U.S.C. 7410(k), 40 CFR 52.02(a)). Thus, in reviewing SIP submissions, EPA's role is to approve state choices, provided that they meet the criteria of the CAA. Accordingly, this proposed action merely approves some state law as meeting federal requirements; this proposed action does not impose additional requirements beyond those imposed by state law. For that reason, this proposed action:

• Is not a “significant regulatory action” subject to review by the Office of Management and Budget under Executive Order 12866 (58 FR 51735, October 4, 1993);
• Does not impose an information collection burden under the provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
• Is certified as not having a significant economic impact on a substantial number of small entities under the Regulatory Flexibility Act (5 U.S.C. 601 et seq.);
• Does not contain any unfunded mandate or significantly or uniquely affect small governments, as described in the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4);
• Does not have federalism implications as specified in Executive Order 13132 (64 FR 43255, August 10, 1999);
• Is not an economically significant regulatory action based on health or safety risks subject to Executive Order 13045 (62 FR 19885, April 23, 1997);
• Is not a significant regulatory action subject to Executive Order 13211 (66 FR 28355, May 22, 2001);
• Is not subject to requirements of section 12(d) of the National Technology Transfer and Advancement Act of 1995 (15 U.S.C. 272 note) because application of those requirements would be inconsistent with the CAA; and,
• Does not provide EPA with the discretionary authority to address, as appropriate, disproportionate human health or environmental effects, using practicable and legally permissible methods, under Executive Order 12898 (59 FR 7629, February 16, 1994).

The SIP is not approved to apply on any Indian reservation land or in any other area where EPA or an Indian tribe has demonstrated that a tribe has jurisdiction. In those areas of Indian country, the rule does not have tribal implications and will not impose substantial direct costs on tribal governments or preempt tribal law as specified by Executive Order 13175 (65 FR 67249, November 9, 2000).
