2Our 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. 

3Rules 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.

[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

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. 

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 nonCTG VOC sources, Colorado has RACTlevel 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 NOX in this document because there 

are certain NOX 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 3 4.

11126 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Rules and Regulations 

4See 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 NOX

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

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: 


khammond on DSKJM1Z7X2PROD with RULES
11128 Federal Register / Vol. 86, No. 35 / Wednesday, February 24, 2021 / Rules and Regulations 

• 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); 

• Is not an Executive Order 13771 (82 

FR 9339, February 2, 2017) regulatory 

action because SIP approvals are 

exempted under Executive Order 12866; 

• 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, 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). 

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)).
