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 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: On May 31, 2017, the State of 

Colorado submitted State 

Implementation Plan (SIP) revisions 

related to attainment of the 2008 8-hour 

ozone National Ambient Air Quality 

Standard (NAAQS) for the Denver 

Metro/North Front Range (DMNFR) 

Moderate nonattainment area by the 

applicable attainment date of July 20, 

2018. The Environmental Protection 

Agency (EPA) is approving the majority 

of the submittal, as well as revisions 

made to Colorado’s Reg. No. 7 in a May 

5, 2013 SIP submission. The EPA is 

deferring action on portions of the 

submitted reasonably available control 

technology (RACT) rules. This action is 

being taken in accordance with the 

Clean Air Act (CAA). 

DATES: Effective August 2, 2018.

SUPPLEMENTARY INFORMATION: 

I. Background 

The DMNFR nonattainment area 

includes Adams, Arapahoe, Boulder, 

Broomfield, Denver, Douglas and 

Jefferson Counties, and portions of 

Larimer and Weld Counties. See 40 CFR 

81.306. The area was designated 

nonattainment for the 2008 ozone 

NAAQS effective July 20, 2012 (77 FR 

30088, May 21, 2012) and reclassified as 

a Moderate ozone nonattainment area 

on May 4, 2016 (81 FR 26697; see 40 

CFR 81.306). Moderate areas are 

required to attain the 2008 8-hour ozone 

NAAQS by no later than 6 years after 

the effective date of designation, which 

for the DMNFR nonattainment area is 

July 20, 2018. See 40 CFR 51.903. 

On April 6, 2018, 83 FR 14807, the 

EPA proposed approval of certain 

revisions to Colorado’s SIP submitted to 

the EPA on May 5, 2013, and May 31, 

2017. Specifically, we proposed 

approval of Colorado’s 2017 attainment 

demonstration for the 2008 8-hour 

ozone NAAQS. In addition, we 

proposed approval of the motor vehicle 

emissions budgets (MVEB) contained in 

the State’s 2017 submittal. We also 

proposed approval of all other aspects of 

the 2017 submittal, except for certain 

area source categories and major source 

RACT, which we will be acting on at a 

later date. We proposed approval of the 

revisions to Colorado’s Reg. 7 and 11, 

except for Sections X.E and XIX of Reg. 

7, which we will be acting on at a later 

date. We proposed approval of the 

revisions to Colorado Reg. 7 Section XII 

from the State’s May 5, 2013 submittal. 

The factual and legal background for 

this action is discussed in detail in our 

April 6, 2018 proposed approval. 83 FR 

14807. The proposal provides a detailed 

description of the revisions and the 

rationale for the EPA’s proposed 

actions. 

II. Response to Comments 

We received nineteen comments 

during the public comment period. 

After reviewing the comments, the EPA 

has determined that sixteen of the 

comments are outside the scope of our 

proposed action or fail to identify any 

material issue necessitating a response. 

We received two comments supporting 

our proposal to approve the DMNFR 

moderate nonattainment area attainment 

demonstration and related revisions, 

and one adverse comment. Below is a 

summary of the material comments and 

the EPA’s responses. 

Comments From Colorado Department 

of Public Health and Environment 

The Colorado Department of Public 

Health and Environment (CDPHE) stated 

that ‘‘Colorado supports EPA’s proposal 

to approve the DMNFR moderate 

nonattainment area attainment 

demonstration and many of the related 

revisions.’’ The State further requested 

that the EPA delay taking action on the 

combustion adjustment and tuning work 

practice requirements in Reg. 7, Section 

XVI.D, due to ‘‘Colorado’s ongoing 

efforts to further establish RACT for 

combustion sources on a categorical 

basis.’’ Colorado stated that it 

anticipates submitting to the EPA 

additional RACT standards for 

combustion equipment in Summer 

2019, and requested that the EPA delay 

action on Reg. 7, Section XVI.D 

revisions from the May 31, 2017 

submittal so that the Agency ‘‘can 

incorporate and approve Colorado’s 

RACT standards for combustion 

equipment all at once.’’ 

Response: The Agency acknowledges 

the State’s support for this action. We 

agree with the request that we refrain 

from acting on Reg. 7, Section XVI.D of 

Colorado’s May 31, 2017 submittal, 

which established RACT as a work 

practice for combustion equipment at 

major sources of nitrogen oxide (NOX) 

emissions. In our notice of proposed 

rulemaking, we proposed to approve all 

of Reg. 7, Section XVI, but explained 

that we would be acting on Colorado’s 

RACT demonstration for major sources 

in a future rulemaking and identified 

provisions for which we were taking no 

action on at the time (see sections H and 

N of the proposed rulemaking). The 

State’s desire to incorporate Section 

XVI.D into its anticipated combustion 

equipment RACT submission is 

reasonable, and because Colorado did 

not rely on any emission reductions 

from control requirements in Section 

XVI.D in its 2017 modeling analysis, we 

are able to act on this revision in a 

separate action. We, therefore, agree 

with the State’s comment and will act 

on revisions to Reg. 7, XVI.D from the 

May 31, 2017 submittal at a later time. 

Comment From Anonymous 

The comment described the approval 

of the State’s revised SIP as ‘‘a necessary 

step’’ that ‘‘will hold owners and 

operators more accountable for their 

actions,’’ and cited several specific 

provisions as beneficial. The commenter 

urged future action on the changes made 

to Reg. 7, Sections X and section XIX, 

and also urged ‘‘every revision and 

action’’ to meet the ozone standard. 

Response: The EPA agrees that the SIP 

provisions we are approving, which will 

be enforceable as a matter of federal law, 

are necessary steps to comply with the 

CAA and protect air quality. We are 

taking no action in this final rule on the 

State submissions concerning Reg. No. 

7, Sections X.E. and XIX, but do intend 

to act on them in a later rulemaking. 

Further, we will continue our ongoing 

work to assist the State in its

1As noted above, attainment demonstration 

modeling assumes that the future meteorology will 

be identical to that in the baseline period, but yearto-year variability in meteorology means that actual 

measurements of ozone in future modeled years 

cannot match that predicted by models. In addition, 

monitoring data may not always accurately reflect 

conditions in the area, such as during times of 

exceptional events. 

2See CAA section 181(b)(2)(A), 42 U.S.C. 

7511(b)(2)(A), the EPA’s implementing regulations 

at 40 CFR 51.1103, and 2008 Ozone Implementation 

Rule (80 FR 12292). 

development of measures to improve air 

quality. 

Comments From the Center for 

Biological Diversity 

Comment 1 

The comment stated that the ‘‘EPA 

must disapprove the attainment 

designation [sic; rightly 

‘‘demonstration’’] because the N. Front 

Range nonattainment area did not attain 

by the attainment deadline’’ and that the 

‘‘EPA must disapprove the attainment 

demonstration because it was 

demonstrable [sic] wrong.’’ The 

comment said that ‘‘EPA has used the 

excuse of ignoring ozone values if the 

comment period or decision is before 

the May 1 deadline for certifying data’’ 

and that the time the comment was 

submitted was after May 1. The 

comment also explained that ‘‘EPA uses 

the exceptional event provision as 

another excuse. However, in Table 1 

[from the commenter], which is 

generated from data from EPA’s Air 

Quality System (AQS), we have 

excluded exceptional events even 

though Colorado’s claims of exceptional 

events are not valid.’’ 

Response: We do not agree with the 

commenter’s argument that the EPA 

should disapprove the attainment 

demonstration because the area did not 

attain by the attainment deadline, or 

with the commenter’s assertions 

concerning exceptional events and the 

timing of the submission. 

Colorado has satisfied the legal and 

regulatory criteria for approving 

attainment demonstration SIPs. An 

attainment demonstration uses 

photochemical grid modeling to show 

that SIP controls are sufficient to reduce 

predicted ambient ozone levels to a 

level at or below the standard, assuming 

identical meteorology in the baseline 

and future (modeled) years. As 

explained in section IV.D and E of the 

proposed rulemaking, to predict future 

ozone levels the modeled attainment 

demonstration uses a baseline design 

value derived from historical data (in 

this case 2009–2013), historical 

meteorological data from the baseline 

period, emission inventories 

representing the baseline design value 

period, and modeled reductions in 

emissions based on SIP control 

measures. The attainment 

demonstration is not required to 

identically match actual monitored 

ozone levels for the future years 

described in the model.1 Rather, it is 

intended to assess whether SIP controls 

are adequate to reduce ambient ozone to 

a level at or below the NAAQS by the 

attainment date, and such an assessment 

is based on modeling. The modeled 

attainment demonstration can be an 

approvable SIP element, even if actual 

monitored data do not show attainment. 

Applying this standard, Colorado’s 

attainment demonstration qualifies for 

EPA approval. As described in the 2008 

Ozone Implementation Rule (80 FR 

12292), ‘‘[t]o demonstrate attainment, 

the modeling results for the 

nonattainment area must predict that 

emissions reductions implemented by 

the beginning of the last full ozone 

season preceding the attainment date 

will result in ozone concentrations that 

meet the level of the standard’’ (80 FR 

12270, March 6, 2015). We find the 

attainment demonstration submitted on 

May 31, 2017, adequate to meet this 

requirement. 

The EPA acknowledges that 2014– 

2016 and 2015–2017 monitored design 

values in the Denver nonattainment area 

violate the 2008 ozone NAAQS, 

regardless of whether all data are used, 

or whether instead, potential 

exceptional event data (which have not 

been acted on by the EPA) are removed. 

But under the CAA, a determination of 

whether an area has failed to attain is a 

separate action entirely from the review 

of an attainment demonstration SIP. The 

EPA’s SIP review occurs under CAA 

section 110(k), 42 U.S.C. 7410(k), while 

a determination of whether an area has 

failed to attain is governed by CAA 

section 181(b)(2), 42 U.S.C. 7511(b)(2). 

Under section 181(b)(2), the EPA must 

determine whether an ozone 

nonattainment area has attained the 

applicable NAAQS ‘‘[w]ithin 6 months 

following the applicable attainment date 

(including any extension thereof).’’ 

(Emphasis added.) Here, the applicable 

attainment date is still in the future: July 

20, 2018. After that date, the EPA will 

analyze the pertinent information and 

determine whether the DMNFR 

nonattainment area has attained the 

NAAQS by the applicable attainment 

date in accordance with section 

181(b)(2). In the event that the EPA 

determines that the area failed to attain 

based on certified air quality data, the 

DMNFR nonattainment area may be 

reclassified to Serious by operation of 

law, and would then be subject to a 

number of Serious area attainment 

planning and control requirements, 

including developing and submitting a 

new attainment demonstration. 

In addition, it is possible that 

Colorado will request and receive an 

extension of the attainment date if that 

is required, as is envisioned in section 

181(b)(2). The CAA allows for up to two 

attainment date extensions, if the fourth 

maximum 8-hour average ozone 

concentration in the attainment year 

(2017 in this case) is below the level of 

the standard.2 Thus, a nonattainment 

area may be able to attain the NAAQS 

by the extended attainment date, even if 

the measured design value for an area 

does not meet the NAAQS at the end of 

the original attainment year, if the area 

is eligible for and is granted an 

attainment date extension. The original 

attainment date has not yet passed, and 

it is possible that the attainment date 

will be extended per section 181(b)(2). 

As previously noted, the Colorado SIP 

submission satisfies the requirements 

for a modeled demonstration that the 

area will meet the standard in the 

attainment year. 

Comment 2 

The commenter also criticized EPA’s 

approach to calculating design values 

for using figures that are ‘‘truncated 

rather than rounded.’’ 

Response: Rules for calculating 

monitored ozone design values for the 

2008 ozone NAAQS are in 40 CFR part 

50, appendix P. Section 2.1 of appendix 

P requires that hourly average ozone be 

truncated to the third decimal place 

(0.001 ppm), as shall 8-hour averages 

compiled from the individual 1-hour 

averages. Section 2.2 of appendix P then 

requires that 3-year averages of annual 

fourth highest 8-hour averages also be 

truncated to the third decimal place. 

The truncation is thus in compliance 

with the procedure required by the 

regulations. 

III. Final Action 

We are approving the SIP submittal 

from the State of Colorado for the 

DMNFR ozone nonattainment area 

submitted on May 31, 2017. 

Specifically, we are approving the 

following: 

• Attainment demonstration with 

weight of evidence analysis for the 2008 

ozone NAAQS; 

• Base and future year emissions 

inventories; 

• RFP demonstration; 

• Demonstration of RACT for Volatile 

Organic Compounds (VOC) Control

• Demonstration of RACM 

implementation; 

• Motor vehicle inspection and 

maintenance program revisions in 

Colorado’s Reg. No. 11; 

• NNSR program; 

• Contingency measures plan; 

• MVEBs; and 

• Revisions to Colorado’s Reg. No. 7 

(except for revisions to Reg. No. 7, 

Section X pertaining to VOC controls of 

industrial cleaning solvents, Section 

XVI.D revisions pertaining to RACT 

standards for combustion equipment, 

and Section XIX revisions pertaining to 

RACT requirements for major sources as 

to which we are not taking any action). 

We are also approving SIP revisions to 

Reg. No. 7 submitted by the State on 

May 13, 2013, except for provisions that 

have been superseded by later 

submissions, for which we are not 

taking any action. We are approving 

these actions in accordance with section 

110, 42 U.S.C. 7410, and part D of the 

CAA. 

IV. Incorporation by Reference 

In this rule, 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 

Reg. No. 11 pertaining to regulation of 

the State’s motor vehicle emissions 

inspection program and Colorado Reg. 

No. 7 pertaining to regulation of sources 

of VOC and NOX emissions as discussed 

in section IV., J. Motor Vehicle 

Inspection and Maintenance Program (I/ 

M) Program and N. SIP Control 

Measures (except we are not acting on 

Reg. 7, Sections, X, XVI.D, and XIX in 

this action) of this preamble. 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.3

V. Statutory and Executive Order 

Reviews 

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 actions, 

provided that they meet the criteria of 

the CAA. Accordingly, this action 

merely approves some state law 

provisions as meeting federal 

requirements; this action does not 

impose additional requirements beyond 

those imposed by state law. For that 

reason, this action: 

• 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, 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 Clean Air Act; 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). 

In addition, the SIP does not 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). 

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. The 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 CAA, 

petitions for judicial review of this 

action must be filed in the United States 

Court of Appeals for the appropriate 

circuit by September 4, 2018. 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 CAA 

section 307(b)(2).)
