ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R08-OAR-2020-0114; FRL-10019-22-Region 8]


Approval and Promulgation of Implementation Plans; Colorado; 
Revisions to Regulation Number 7 and RACT Requirements for 2008 8-Hour 
Ozone Standard for the Denver Metro/North Front Range Nonattainment 
Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The Environmental Protection Agency (EPA) is approving and 
conditionally approving State Implementation Plan (SIP) revisions 
submitted by the State of Colorado on May 31, 2017, May 14, 2018 and 
May 8, 2019. The revisions are to Colorado Air Quality Control 
Commission (Commission or AQCC) Regulation Number 7 (Reg. 7). The 
revisions to Reg. 7 address Colorado's reasonably available control 
technology (RACT) SIP obligations for Moderate 2008 ozone nonattainment 
areas; add incorporation by reference dates to rules and reference 
methods; and make typographical, grammatical, and formatting 
corrections. Also, in this action the EPA is correcting a July 3, 2018 
final rule pertaining to Colorado's SIP. In that action, we 
inadvertently omitted regulatory text corresponding to ``incorporation 
by reference'' (IBR) materials for graphic arts and printing revisions 
to Reg. 7, Section XIII (adopted November 17, 2016). The EPA is taking 
this action pursuant to the Clean Air Act (CAA).

DATES: This rule is effective on March 26, 2021.

ADDRESSES: The EPA has established a docket for this action under 
Docket ID No. EPA-R08-OAR-2020-0114. All documents in the docket are 
listed on the http://www.regulations.gov website. Although listed in 
the index, some information is not publicly available, e.g., CBI or 
other information whose disclosure is restricted by statute. Certain 
other material, such as copyrighted material, is not placed on the 
internet and will be publicly available only in hard copy form. 
Publicly available docket materials are available through http://www.regulations.gov, or please contact the person identified in the FOR 
FURTHER INFORMATION CONTACT section for additional availability 
information.

FOR FURTHER INFORMATION CONTACT: Abby Fulton, Air and Radiation 
Division, EPA, Region 8, Mailcode 8ARD-IO, 1595 Wynkoop Street, Denver, 
Colorado 80202-1129, (303) 312-6563, <a href="/cdn-cgi/l/email-protection#dfb9aab3abb0b1f1bebdbda69fbaafbef1b8b0a9"><span class="__cf_email__" data-cfemail="c5a3b0a9b1aaabeba4a7a7bc85a0b5a4eba2aab3">[email protected]</span></a>.

SUPPLEMENTARY INFORMATION: Throughout this document ``we,'' ``us,'' and 
``our'' means the EPA. In our October 6, 2020 proposal for this action 
(85 FR 63066) we inadvertently referred to the May 8, 2019 submittals 
as May 10, 2019 submittals. The cover letters to these submittals are 
dated May 10, but they were actually received by EPA on the 8th.

I. Background

    The background for this action is discussed in detail in our 
October 6, 2020 proposal (85 FR 63066). In that document we proposed to 
approve various revisions to the Colorado SIP that were submitted to 
the EPA on May 31, 2017, May 14, 2018 and May 8, 2019. In particular, 
we proposed to approve certain area source rules to meet the 2008 8-
hour ozone national ambient air quality standards (NAAQS) RACT 
requirements for Moderate nonattainment areas that were not acted on in 
our July 3, 2018 rulemaking approving the State's attainment 
demonstration and various SIP elements.\1\ We also proposed to approve 
into the SIP the submitted revisions to Colorado's Reg. 7 that we have 
not previously acted on, except for Sections XII and XVIII (from the 
May 2018 submittal) and Sections XVI.D.4.b.(i) and XVI.D.4.d. (from the 
two May 2019 submittals), which we will be acting on at a later date 
(see Tables 4 and 5 of the preamble to the proposed rule). Finally, we 
proposed to approve IBR material that was submitted in May 2017 but 
inadvertently excluded from our July 3, 2018 action. The factual and 
legal background for this action is discussed in detail in our October 
6, 2020 proposed approval. The proposal provides a detailed description 
of the revisions and the rationale for EPA's proposed actions. We did 
not receive any comments on the proposal.

    \1\ See Final Rule, Approval and Promulgation of State 
Implementation Plan Revisions; Colorado; Attainment Demonstration 
for the 2008 8-Hour Ozone Standard for the Denver Metro/North Front 
Range Nonattainment Area, and Approval of Related Revisions, 83 FR 
31068, 31069-31072.
---------------------------------------------------------------------------

II. Final Action

    The EPA is approving submitted revisions to Sections I, II, III, V, 
VI, VII \2\, VIII, IX, X, XI, XIII, XIV, XV, XVI, XVII, XIX and XX of 
Reg. 7 from the State's May 31, 2017, May 14, 2018 and May 8, 2019 
submittals as shown in Table 1, except for those revisions we are not 
acting on as represented in Table 2. We are approving Colorado's 
determination that the above rules constitute RACT for the specific 
categories addressed in Tables 3 and 4, except for the aerospace 
category, which we are conditionally approving. We are also finding 
that for VOC RACT requirements at major non-CTG VOC sources, Colorado 
has RACT-level controls in place for the DMNFR Area under the 2008 8-
hour ozone standard. We are not finalizing our RACT determination for 
major sources of NO<INF>X</INF> in this document because there are 
certain NO<INF>X</INF> source categories as to which we have not yet 
determined that the State has met RACT requirements. We will be 
addressing those categories and requirements in a future action 
<SUP>3 4</SUP>.
---------------------------------------------------------------------------

    \2\ Our October 6 proposal incorrectly stated at one point that 
one of the State's May 8, 2019 SIP submittals contained revisions to 
Reg. 7, Section VII. See 85 FR at 63074. In fact, neither of the 
State's submittals on that date involved revisions to Section VII. A 
correct and complete list of the affected provisions appears at 
Table 4 of our October 6 proposal, and in Table 1 of this final 
rule.
    \3\ Rules in this column were struck from Colorado's regulation 
number 7 in the May 8, 2019 submittal--RACT for brewing related 
activities and wood furniture surface coating operations. Because 
these rules were not approved into the SIP from previous submittals, 
there is no action for EPA to take remove them from the SIP.
    \4\ See Colorado's August 4, 2020 letter committing to submit to 
EPA a negative declaration certifying that there are no sources in 
the DMNFR Area above the aerospace CTG applicability threshold 
(contained within the docket). The EPA is conditionally approving 
Colorado's determination that there are no sources in the DMNFR Area 
subject to the aerospace CTG and therefore RACT is satisfied for 
this category. If we finalize our proposed conditional approval, 
Colorado must submit the negative declaration, after state notice 
and public hearing, to EPA within one year of our finalization of 
the conditional approval. If Colorado does not submit the negative 
declaration within one year, or if we find Colorado's revisions to 
be incomplete, or we disapprove Colorado's revisions, this 
conditional approval will convert to a disapproval. If any of these 
occur and our conditional approval converts to a disapproval, that 
will constitute a disapproval of a required plan element under part 
D of title I of the Act, which starts an 18-month clock for 
sanctions, see CAA section 179(a)(2), and the two-year clock for a 
federal implementation plan, see CAA section 110(c)(1)(B).

III. Incorporation by Reference

    In this document, the EPA is finalizing regulatory text that 
includes incorporation by reference. In accordance with requirements of 
1 CFR 51.5, the EPA is finalizing the incorporation by reference of 
Colorado Regulation Number 7 pertaining to regulation of sources of VOC 
and NO<INF>X</INF> emissions, except that we are not acting on Reg. 7, 
Sections II.B., XII, XVI.D.4.b.(i), XVI.D.4.d., and XVIII in this 
action.\5\ Therefore, these materials have been approved by the EPA for 
inclusion in the State implementation plan, have been incorporated by 
reference by the EPA into that plan, are fully federally enforceable 
under sections 110 and 113 of the CAA as of the effective date of the 
final rulemaking of the EPA's approval, and will be incorporated by 
reference by the Director of the Federal Register in the next update to 
the SIP compilation.\6\ The EPA has made, and will continue to make, 
these materials generally available through www.regulations.gov and at 
the EPA Region 8 Office (please contact the person identified in the 
FOR FURTHER INFORMATION CONTACT section of this preamble for more 
information). Therefore, these materials have been approved by the EPA 
for inclusion in the SIP, have been incorporated by reference by the 
EPA into that plan, are fully federally enforceable under sections 110 
and 113 of the CAA as of the effective date of the final rulemaking of 
the EPA's approval, and will be incorporated by reference in the next 
update to the SIP compilation.\7\

Reg. 7) of our October 6 proposed rule for additional discussion. 85

IV. Statutory and Executive Order Reviews

    Under the Clean Air Act, 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 action merely approves state law as meeting Federal requirements 
and does not impose additional requirements beyond those imposed by 
state law. For that reason, this action:

    <bullet> Is not a ``significant regulatory action'' subject to 
review by the Office of Management and Budget under Executive Orders 
12866 (58 FR 51735, October 4, 1993) and 13563 (76 FR 3821, January 21, 
2011);
    <bullet> Is not an Executive Order 13771 (82 FR 9339, February 2, 
2017) regulatory action because SIP approvals are exempted under 
Executive Order 12866;
    <bullet> Does not impose an information collection burden under the 
provisions of the Paperwork Reduction Act (44 U.S.C. 3501 et seq.);
    <bullet> 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.);
    <bullet> Does not contain any unfunded mandate or significantly or 
uniquely affect small governments, described in the Unfunded Mandates 
Reform Act of 1995 (Pub. L. 104-4);
    <bullet> Does not have Federalism implications as specified in 
Executive Order 13132 (64 FR 43255, August 10, 1999);
    <bullet> Is not an economically significant regulatory action based 
on health or safety risks subject to Executive Order 13045 (62 FR 
19885, April 23, 1997);
    <bullet> Is not a significant regulatory action subject to 
Executive Order 13211 (66 FR 28355, May 22, 2001);
    <bullet> 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
    <bullet> 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).
    In addition, 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).
    The Congressional Review Act, 5 U.S.C. 801 et seq., as added by the 
Small Business Regulatory Enforcement Fairness Act of 1996, generally 
provides that before a rule may take effect, the agency promulgating 
the rule must submit a rule report, which includes a copy of the rule, 
to each House of the Congress and to the Comptroller General of the 
United States. EPA will submit a report containing this action and 
other required information to the U.S. Senate, the U.S. House of 
Representatives, and the Comptroller General of the United States prior 
to publication of the rule in the Federal Register. A major rule cannot 
take effect until 60 days after it is published in the Federal 
Register. This action is not a ``major rule'' as defined by 5 U.S.C. 
804(2).
    Under section 307(b)(1) of the Clean Air Act, petitions for 
judicial review of this action must be filed in the United States Court 
of Appeals for the appropriate circuit by April 26, 2021. Filing a 
petition for reconsideration by the Administrator of this final rule 
does not affect the finality of this action for the purposes of 
judicial review nor does it extend the time within which a petition for 
judicial review may be filed, and shall not postpone the effectiveness 
of such rule or action. This action may not be challenged later in 
proceedings to enforce its requirements. (See section 307(b)(2)).
