3For the definition of the Bullhead City 

maintenance area, see 40 CFR 81.303. The Bullhead 

City maintenance area is located in western 

Arizona. The original nonattainment area was 

defined by the equivalent of approximately six 

townships covering more than 200 square miles: 

T21N, R20–21W, excluding Lake Mead National 

Recreation area; T20N, R20–22W; and T19N, R21– 

22W, excluding the Fort Mohave Indian 

Reservation. On June 26, 2002, the EPA approved 

the State’s request that some areas of undisturbed 

desert terrain containing no industrial or 

commercial activity be excluded from the Bullhead 

City PM10 planning area (67 FR 43020, 43022). As 

a result of the boundary change, the townships 

comprising the maintenance area include: T21N, 

R21W, excluding Lake Mead National Recreation 

Area; T20N, R21–22W; and T19N, R22W, excluding 

the Fort Mohave Indian Reservation.

IV. Statutory and Executive Order Reviews 

I. Background 

The EPA has established health-based 

standards for PM10. On July 1, 1987, the 

EPA promulgated two standards for 

PM10: A 24-hour standard of 150 

micrograms per cubic meter (mg/m3) and 

an annual PM10 standard of 50 mg/m3.1

Effective December 18, 2006, the EPA 

revoked the annual PM10 standard but 

retained the 24-hour PM10 standard.2 In 

this document, references to the PM10

NAAQS or PM10 standard refer to the 

24-hour average standard of 150 mg/m3, 

unless otherwise noted. 

Under section 107(d) of the Clean Air 

Act (CAA or ‘‘Act’’), the EPA is required 

to designate areas of the country, based 

on ambient air quality data, as 

attainment, unclassifiable, or 

nonattainment for each NAAQS. Under 

the CAA Amendments of 1990, the 

Bullhead City area was designated as 

part of a large ‘‘unclassifiable’’ area in 

Arizona for the PM10 NAAQS.3 In 1993, 

in light of PM10 NAAQS violations 

monitored in 1989 and 1990, the EPA 

redesignated the Bullhead City area as a 

‘‘Moderate’’ nonattainment area for the 

PM10 standard.4 To meet the SIP 

planning requirements for such areas, 

state and local agencies adopted and 

implemented a number of control 

measures to reduce PM10 emissions and 

lower ambient PM10 concentrations in 

the Bullhead City area, including paving 

of certain unpaved roads. In 2002, the 

EPA determined that the Bullhead City 

area had attained the PM10 NAAQS by 

the applicable attainment date of 

December 31, 2000.5 The 24-hour 

standard is attained when the expected 

number of days with levels above 150 

mg/m3 (averaged over a 3-year period) is 

less than or equal to one. 

Under CAA section 175A, one of the 

criteria for an area to be redesignated 

from nonattainment to attainment is the 

approval of a maintenance plan. The 

maintenance plan must, among other 

requirements, ensure control measures 

are in place such that the area will 

continue to maintain the standard for 

the period extending 10 years after 

redesignation and include contingency 

provisions to assure that violations of 

the NAAQS will be promptly remedied. 

In 2002, the Arizona Department of 

Environmental Quality (ADEQ) 

submitted a maintenance plan, titled 

‘‘Bullhead City Moderate Area PM10

Maintenance Plan and Request for 

Redesignation to Attainment’’ (February 

2002) (‘‘First 10-Year LMP’’) to the EPA 

as a revision to the Arizona SIP, and 

requested that the EPA redesignate the 

Bullhead City area to attainment.6 The 

First 10-Year LMP provided for 

maintenance of the PM10 NAAQS in the 

Bullhead City area for 10 years after 

redesignation. On June 26, 2002, the 

EPA approved the First 10-Year LMP for 

the Bullhead City area as providing for 

maintenance through 2012.7

CAA section 175A(b) requires states 

to submit an additional SIP revision to 

maintain the NAAQS for 10 years after 

the expiration of the 10-year period 

covered by the initial maintenance plan 

approved in connection with the 

redesignation of the area from 

nonattainment to attainment. On May 

24, 2012, ADEQ submitted a second 10- 

year maintenance plan, titled ‘‘Limited 

Maintenance Plan Update for the 

Bullhead City PM10 Maintenance Area’’ 

(May 2012) (‘‘Second 10-Year LMP’’), to 

meet the requirement for the subsequent 

maintenance plan under CAA section 

175A(b). The Second 10-Year LMP is 

intended to provide for continued 

maintenance of the PM10 NAAQS for the 

10-year period following the end of the 

first 10-year period, i.e., through June 

2022. 

Consistent with the requirements at 

the time, the First 10-year LMP 

provided for maintenance of both the 

24-hour average and annual average 

PM10 NAAQS. However, because the 

EPA has revoked the annual average 

PM10 NAAQS, the Second 10-Year LMP 

addresses only maintenance of the 24- 

hour PM10 NAAQS. 

On December 9, 2021, the EPA 

proposed to approve as a revision to the 

Arizona SIP the Second 10-Year LMP 

submitted by ADEQ on May 24, 2012, 

for the Bullhead City area.8 The EPA 

proposed to approve this plan based on 

the conclusion that it adequately 

provides for continued maintenance of 

the PM10 NAAQS in the Bullhead City 

area through 2022 and thereby meets the 

requirements for subsequent 

maintenance plans under section 175A 

of the Act. Our proposed action contains 

more information on the plan and our 

evaluation. 

II. Public Comments 

The EPA’s proposed action provided 

a 30-day public comment period. During 

this period, we received two comments. 

Both comments were supportive of our 

proposed action and do not require a 

response. The comments are available 

for viewing in the docket for this 

rulemaking. 

III. Final Action 

No comments were submitted that 

change our assessment of the Second 

10-Year LMP as described in our 

proposed action. Therefore, as 

authorized in section 110(k)(3) of the 

Act, the EPA is taking final action to 

approve as a revision to the Arizona SIP 

the Second 10-Year LMP for the 

Bullhead City area for the PM10 NAAQS. 

The EPA is approving this plan based 

on the conclusion that it adequately 

provides for continued maintenance of 

the PM10 NAAQS in the Bullhead City 

area through 2022 and thereby meets the 


lotter on DSK11XQN23PROD with RULES1
22134 Federal Register / Vol. 87, No. 72 / Thursday, April 14, 2022 / Rules and Regulations 

requirements for subsequent 

maintenance plans under section 175A 

of the Act. The effect of this action is to 

make the State’s continuing 

commitments federally enforceable for 

the second 10-year maintenance period 

with respect to maintenance of the PM10

NAAQS in the Bullhead City area. 

These commitments include continued 

monitoring; continued implementation 

of control measures that were 

responsible for bringing the area into 

attainment; preparation and submittal of 

annual reports; consideration and 

implementation of contingency 

measures, as necessary; and submittal of 

a full maintenance plan if contingency 

measures fail to provide the required 

remedy. 

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 Clean Air 

Act. 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: 

• 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); 

• 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 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). 

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 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 June 13, 2022. 

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).)

quality standards of the Clean Air Act’’

Maricopa County’’ to reduce the impacts
