Revisions to PM2.5 Significant Impact Level (SIL) and Significant Monitoring Concentration (SMC) Provisions
Colorado's SIP submittal revises the SIL and SMC provisions for PM2.5 in the State's Prevention of Significant Deterioration (PSD) permitting program. On January 22, 2013, the United States Court of Appeals for the District of Columbia Circuit vacated the SILs for PM2.5 and allowed the EPA to reconsider the provisions for SMCs. Sierra Club v. EPA, 705 F.3d 458 (D.C. Cir. 2013). On December 9, 2013, the EPA issued a final rule that removes the PM2.5 SIL from EPA's PSD regulations and revised the threshold for SMCs (78 FR 73698). The EPA set the PM2.5 SMC concentration at zero micrograms per cubic meter instead of removing PM2.5 entirely from the SMC provisions because a zero micrograms per cubic meter threshold means there is no air quality impact below which a reviewing authority has the discretion to exempt a source from the PM2.5 monitoring requirements, but that monitoring is still required. As a result of this court decision and the EPA's rulemaking, Colorado removed the SILs for PM2.5 from Part D, Section V.A.2.c set the SMC monitoring concentration to zero in Part D, Section VI.B.3.a(iii).Start Printed Page 39397
Revisions to APEN Reporting
Colorado's regulations in Part A, Section II.A. require:
[N]o person shall allow emissions of air pollutants from, or construction, modification or alteration of, any facility, process, or activity which constitutes a stationary source, except residential structures, from which air pollutants are, or are to be, emitted unless and until an Air Pollution Emission Notice and the associated Air Pollution Emission Notice fee has been filed with the Division with respect to such emission.
Colorado has revised its APEN reporting requirements to clarify when a revised APEN is required due to a significant change in annual actual emissions. The revision would clarify that the thresholds for determining significant changes are based on individual emission units, not facility-wide, actual emissions on a pollutant-by-pollutant basis. For example, an APEN reporting 150 tons per year (tpy) of carbon monoxide (CO) and 10 tpy of PM2.5 would need to update CO emissions using the “one hundred tpy or more” threshold in Part A, Section II.C.2.b.(iii), and update PM2.5 emissions using the “less than one hundred tpy” threshold in Part A, Section II.C.2.b.(i). Without this proposed clarification (actual emissions on a pollutant-by-pollutant basis) a significant change was based on the source's aggregate annual actual emissions, which required sources to file revised APENs more often.
Colorado has also revised Part A, Section II.C.b(i)-(iii), Section II.C.4.a. and b. to clarify that APENs filed solely to update an expired APEN, change the owner or operator, or report a significant change in emissions need only report actual annual emissions (which is the equivalent of controlled emissions if the source utilizes emission control equipment). APENs filed to update control equipment or modify a permit limitation would continue to report both uncontrolled actual and controlled actual emissions. This revision simplifies and streamlines the requirements for filing revised APENs, because the source's actual annual emissions are the relevant information for inventory and fee purposes when reporting past years' emissions or reporting significant changes in annual actual emissions.
Revisions to Public Notice Requirements
Colorado has revised its provisions for public notice of a minor source permit application to update the publication requirements in Part B, Section III.C.4. Regulation 3 in the SIP requires the State to publish public notice of certain proposed minor source construction permit applications, including sources that apply for a permit to limit the potential to emit criteria pollutants, in a newspaper of general distribution in the area where the proposed project will be located or by other such method reasonably designed to ensure effective public notice. Recently, Colorado has found that some areas where construction permitting projects require public notice are proposed no longer have newspapers of general circulation. Therefore, in order to provide effective public notice, Colorado has revised its minor source public notice publication requirements to include other means authorized by state statute and federal regulation that are designed to provide public notice of the applicable permitting action. Further, by utilizing other means of public notice such as the State Web site, Colorado will provide broader notice for a longer timeframe than a one-day publication in a newspaper.
III. What are the changes that EPA is proposing to approve?
Under CAA section 110(l), EPA cannot approve a SIP revision that interferes with any requirement concerning attainment, reasonable further progress, or any other applicable requirement of the Act. The February 25, 2015 revisions to Regulation 3 Part D, Section VI.A.2.c and VI.B.3.a.(iii) of the Colorado SIP would not interfere with the applicable requirements of the Act. The revisions to the PSD program in Part D, Regulation 3 comply with the requirements of 40 CFR 51.166 as revised by the EPA in response to the D.C. Circuit Court of Appeals decision regarding PM2.5 SILs and SMCs. See 78 FR 73698. This proposal is limited to the revisions pertaining to PM2.5; we are not proposing to re-approve any existing provisions in the Colorado SIP regarding source impact analysis and ambient monitoring. As the revisions removing PM2.5 SILs and SMCs are in accordance with the EPA's 2013 removal of PM2.5 SILs and SMCs from 40 CFR 51.166 and the revisions strengthen the SIP, we are proposing to approve the revisions. We are also proposing to approve the conforming change to the introductory statement in VI.A.2., which includes the deletion of the phrase at the end of the sentence (“, as clarified for any relevant air pollutant in Section VI.A.2.c.:”). The revisions to Part A, Section II.C.b(i)-(iii), Section II.C.4.a. and b. comply with section 110(l) because the revisions are limited to the filing of revised APENs that are designed to update Colorado's emissions inventory or used to calculate emissions fees. The revisions to the public notice minor source permitting requirements comply with section 110(l) because as discussed below, we propose to interpret that revisions are consistent with our regulations and guidance.
Colorado's February 25, 2015 submittal also revises its APEN requirements. The APEN revisions in Part A clarify that, for purposes of filing a revised APEN, the thresholds for determining significant changes are based on the emission unit's actual emissions on a pollutant-by-pollutant basis, not total facility-wide emissions. These revisions also clarify that APENs filed for the following purposes need only report actual emissions: Solely to update an APEN before it expires; change in the owner or operator of any facility, process of activity; or report a significant change in emissions. APENs filed to update control equipment or modify a permit limitation would continue to report both uncontrolled actual and controlled actual emissions. The revisions to Part A, Section II.C.2.b(i)-(iii), Section II.C.4.a. and b streamline the requirements for filing revised APENs because the sources actual annual emissions is the relevant information for emissions inventory and fee purposes.
The CAA contains three programs governing construction of new and modified stationary sources, collectively referred to as new source review (NSR): Minor NSR, PSD, and nonattainment NSR.
The revisions in the February 25, 2015 submittal to the public notice requirements in Regulation 3, Part B, Section III.C.4 apply only to the minor NSR program. They do not apply to the PSD and nonattainment NSR permit programs, which have separate public notice requirements in Regulation 3, Part D, Section IV.A.
Requirements for the minor NSR program are provided in 40 CFR 51.160 to 51.164. With respect to public notice of minor NSR approvals, the state must provide “a notice by prominent advertisement in the area affected.” 40 CFR 51.161(b)(3). On April 17, 2012, the EPA issued a guidance memorandum stating that we intended to interpret “prominent advertisement” in a media-neutral fashion.
The memorandum explained that states could meet the requirement by publication of the notice Start Printed Page 39398in appropriate newspaper, or could opt to publish the notice using other media so long as it would be reasonable to conclude that the public would have routine and ready access to the alternative publishing venue and the use of the alternative venue would be consistent with the state's law or SIP.
On October 18, 2016 (81 FR 71613) the EPA revised the public notice requirements for Clean Air Act permitting programs.
In the 2016 final action, the EPA also revised the April 17, 2012 interpretation of “prominent advertisement” in 40 CFR 51.161(b)(3) for the minor NSR program by extending it to “synthetic minor” permits, that is, permits that contain legally and practically enforceable restrictions that result in the source not being subject to major NSR requirements. 81 FR 71617.
In this action, the EPA proposes to interpret “prominent advertisement” in similar fashion, that is, as media neutral and satisfied by any publishing venue to which it would be reasonable to conclude the public has routine and ready access. The February 25, 2015 SIP revisions require the public notice to be published in either a newspaper of general distribution in the area in which the source is or will be located, or by other means necessary to assure notice to the affected public, including posting notice on the publicly accessible portion of the Division's Web site. We propose to determine that this is adequate as “prominent advertisement.” We are not proposing to reassess Colorado's minor NSR program with respect to public participation processes generally; we are only proposing to act on revisions that affect the publication of the notice specifically. This proposal is limited to the revisions as they apply to the SIP and criteria pollutants; we are not proposing action on provisions regarding “federal hazardous air pollutants” that are covered under authorities.
For the reasons expressed above, EPA is proposing to approve revisions to Regulation 3, Parts A, B and D and Appendix A from the February 25, 2015 submittal as shown in Table 1 below. Appendix A was revised as a conforming change to the APEN revisions. We are also proposing to approve the renumbering and formatting changes for the definition of “emission unit” in Regulation 3, Part D, I.A.13.a.; and II.A.13.a.(i)-(ii).

The EPA is not acting on revisions from Colorado's February 25, 2015 submittal related to greenhouse gas and carbon dioxide equivalent (CO2e) revisions and the associated renumbering which was a result of Colorado's proposed greenhouse gas revisions in Parts A and D. These revisions will be acted on in a separate future rulemaking.
IV. Incorporation by Reference
In this rule, 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 the Colorado Air Quality Control Commission (Commission) Regulation Number 3, Parts A, B and D discussed in section III 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).
V. 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, the 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 the 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 the 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).
