Federal Register / Vol. 80, No. 153 / Monday, August 10, 2015 / Rules and Regulations 47859 

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 October 9, 2015. 

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).)

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving State 

Implementation Plan (SIP) revisions 

submitted by the State of Arizona to 

address the requirements of section 

110(a)(1) and (2) of the Clean Air Act 

(CAA) for the 2008 Lead (Pb) and 2008 

ozone national ambient air quality 

standards (NAAQS). Section 110(a) of 

the CAA requires that each State adopt 

and submit a SIP for the 

implementation, maintenance, and 

enforcement of each NAAQS 

promulgated by EPA. We refer to such 

SIP revisions as ‘‘infrastructure’’ SIPs 

because they are intended to address 

basic structural SIP requirements for 

new or revised NAAQS including, but 

not limited to, legal authority, 

regulatory structure, resources, permit 

programs, monitoring, and modeling 

necessary to assure attainment and 

maintenance of the standards. In 

addition, we are approving several state 

provisions addressing CAA conflict of 

interest and monitoring requirements 

into the Arizona SIP. 

DATES: This final rule is effective on 

September 9, 2015. 

ADDRESSES: EPA has established a 

docket for this action, identified by 

Docket ID Number EPA–R09–OAR–

I. Background 

II. EPA’s Response to Comments 

III. Final Action 

IV. Incorporation by Reference 

V. Statutory and Executive Order Reviews 

I. Background 

CAA section 110(a)(1) requires each 

state to submit to EPA, within three 

years after the promulgation of a 

primary or secondary NAAQS or any 

revision thereof, an infrastructure SIP 

revision that provides for the 

implementation, maintenance, and 

enforcement of such NAAQS. Section 

110(a)(2) sets the content requirements 

of such a plan, which generally relate to 

the information and authorities, 

compliance assurances, procedural 

requirements, and control measures that 

constitute the ‘‘infrastructure’’ of a 

state’s air quality management program. 

These infrastructure SIP elements 

required by section 110(a)(2) are as 

follows: 

• Section 110(a)(2)(A): Emission 

limits and other control measures. 

• Section 110(a)(2)(B): Ambient air 

quality monitoring/data system. 

• Section 110(a)(2)(C): Program for 

enforcement of control measures and 

regulation of new and modified 

stationary sources. 

• Section 110(a)(2)(D)(i): Interstate 

pollution transport. 

• Section 110(a)(2)(D)(ii): Interstate 

and international pollution abatement. 

• Section 110(a)(2)(E): Adequate 

resources and authority, conflict of 

interest, and oversight of local and 

regional government agencies. 

• Section 110(a)(2)(F): Stationary 

source monitoring and reporting. 

• Section 110(a)(2)(G): Emergency 

episodes. 

• Section 110(a)(2)(H): SIP revisions. 

• Section 110(a)(2)(J): Consultation 

with government officials, public 

notification, PSD, and visibility 

protection. 

• Section 110(a)(2)(K): Air quality 

modeling and submittal of modeling 

data. 

• Section 110(a)(2)(L): Permitting 

fees. 

• Section 110(a)(2)(M): Consultation/

participation by affected local entities. 

Two elements identified in section 

110(a)(2) are not governed by the threeyear submittal deadline of section 

110(a)(1) and are therefore not 

addressed in this action. These two 

elements are: (i) Section 110(a)(2)(C) to 

the extent it refers to permit programs 

required under part D (nonattainment 

NSR), and (ii) section 110(a)(2)(I), 

pertaining to the nonattainment 

planning requirements of part D. As a 

result, this action does not address 

infrastructure for the nonattainment 

NSR portion of section 110(a)(2)(C) or 

the whole of section 110(a)(2)(I). 

On November 12, 2008, the U.S. 

Environmental Protection Agency (EPA) 

issued a revised NAAQS for Pb.1 That 

action triggered a requirement for states 

to submit an infrastructure SIP to 

address the applicable requirements of 

section 110(a)(2) within three years of 

issuance of the revised NAAQS. On 

October 14, 2011, EPA issued 

‘‘Guidance on Section 110 Infrastructure 

SIPs for the 2008 Pb NAAQS’’, referred 

to herein as EPA’s 2011 Pb Guidance.2

Depending on the timing of a given 

submittal, some states relied on the 

earlier draft version of this guidance, 

referred to herein as EPA’s 2011 Draft 

Pb Guidance.3 EPA issued additional 

guidance on infrastructure SIPs on 

September 13, 2013.4

On March 27, 2008, EPA issued a 

revised NAAQS for 8-hour Ozone.5 That 

action triggered a requirement for states 

to submit an infrastructure SIP to 

address the applicable requirements of 

section 110(a)(2) within three years of 

issuance of the revised NAAQS. EPA 

did not, however, prepare guidance at 

that time for states in submitting I–SIP 

revisions for the 2008 Ozone NAAQS.6

On September 13, 2013, EPA issued 

‘‘Guidance of Infrastructure State 

Implementation Plan (SIP) Elements 

under Clean Air Act Sections 110(a)(1) 

and 110(a)(2),’’ which provides advice 

on the development of infrastructure 

SIPs for the 2008 ozone NAAQS (among 

other pollutants) as well as 

infrastructure SIPs for new or revised 

NAAQS promulgated in the future.7

The Arizona Department of 

Environmental Quality (ADEQ) has 

submitted several infrastructure SIP 

revisions pursuant to EPA’s 

promulgation of the NAAQS addressed 

by this rule, including the following: 

• October 14, 2011—‘‘Arizona State 

Implementation Plan Revision under 

Clean Air Act Section 110(a)(1) and (2); 

2008 Lead NAAQS,’’ to address all of 

the CAA section 110(a)(2) requirements, 

except for section 110(a)(2)(G),8 for the 

2008 Pb NAAQS (2011 Pb I–SIP 

Submittal). 

• December 27, 2012—‘‘Arizona State 

Implementation Plan Revision under 

Clean Air Act Section 110(a)(1) and (2); 

2008 8-hour Ozone NAAQS,’’ to address 

all of the CAA section 110(a)(2) 

requirements for the 2008 8-hour Ozone 

NAAQS (2012 Ozone I–SIP Submittal). 

• December 6, 2013—‘‘Submittal of 

Maricopa County Rule 100 revising the 

Maricopa County Portion of the Arizona 

State Implementation Plan for Section 

110(a)(2) Infrastructure’’ from Eric 

Massey, Director of ADEQ (2013 

Maricopa County Submittal). Maricopa 

County Rule 100 was submitted to 

address a deficiency in section 

110(a)(2)(E)(ii) of the SIP for Maricopa 

County concerning conflict of interest 

requirements for hearing boards. 

• December 19, 2013—‘‘Submittal of 

Pima County Rules revising the Pima 

County Portion of the Arizona State 

Implementation Plan for Section 

110(a)(2) Infrastructure’’ from Eric 

Massey, Director of ADEQ (2013 Pima 

County Submittal). This submittal 

included Pima County Rule 17.04.190 

‘‘Composition,’’ adopted September 28, 

1993; Pima County Rule 17.12.040 

‘‘Reporting for Compliance 

Evaluations,’’ adopted September 28, 

1993; and Pima County Rule 17.24.040 

‘‘Reporting Requirements,’’ adopted 

April 19, 2005 for inclusion into the 

Arizona SIP. These rules were 

submitted to address deficiencies in 

section 110(a)(2)(E)(ii) of the SIP 

concerning conflict of interest 

requirements for hearing boards and 

section 110(a)(2)(F) of the SIP 

concerning stationary source monitoring 

and reporting.

• September 4, 2014—‘‘Submittal of 

Pinal County Rule 1–3–140 Revising the 

Pinal County Portion of the Arizona 

State Implementation Plan for Section 

110(a)(2) Infrastructure’’ from Eric 

Massey, Director of ADEQ (2014 Pinal 

County Submittal). This submittal 

included Pinal County Rule 1–3–140 

‘‘Definitions,’’ adopted July 23, 2014 for 

inclusion into the Arizona SIP. Pinal 

County Rule 1–3–140 was submitted to 

address a deficiency in section 

110(a)(2)(E)(ii) of the SIP for Pinal 

County concerning conflict of interest 

requirements for hearing boards. 

II. EPA’s Response to Comments 

The public comment period on EPA’s 

proposed rule opened on November 24, 

2014, the date of its publication in the 

Federal Register at 79 FR 69796, and 

closed on December 24, 2014. During 

that period, EPA did not receive any 

comments. 

III. Final Action 

Under CAA section 110(k)(3) and 

based on the evaluation and rationale 

presented in the proposed rule, the 

technical support document and this 

final rule, EPA is approving the 2011 Pb 

I–SIP Submittal, the 2012 Ozone I–SIP 

Submittal, the 2013 Maricopa County 

Submittal, the 2013 Pima County 

Submittal and the 2014 Pinal County 

Submittal with respect to the following 

infrastructure SIP requirements: 

• Section 110(a)(2)(A): Emission 

limits and other control measures. 

• Section 110(a)(2)(B): Ambient air 

quality monitoring/data system. 

• Section 110(a)(2)(E): Adequate 

resources and authority, conflict of 

interest, and oversight of local and 

regional government agencies. 

• Section 110(a)(2)(F): Stationary 

source monitoring and reporting. 

• Section 110(a)(2)(G): Emergency 

episodes. 

• Section 110(a)(2)(H): SIP revisions. 

• Section 110(a)(2)(L): Permitting 

fees. 

• Section 110(a)(2)(M): Consultation/

participation by affected local entities. 

In addition, we are approving into the 

SIP certain regulatory provisions 

included in the 2013 Pima County and 

Maricopa County Submittals, and in the 

2014 Pinal County Submittal, as 

discussed in the TSD.9

We are not acting today on those 

elements of the infrastructure SIP that 

address the requirements of sections 

110(a)(2)(C), (D), (J) and (K) of the Act. 

On October 29, 2012, ADEQ submitted 

‘‘New Source Review State 

Implementation Plan Submission’’ and 

on July 2, 2014 submitted 

‘‘Supplemental Information to 2012 

New Source Review State 

Implementation Plan Submission’’. 

These submissions address the 

permitting portions of I–SIP elements in 

sections 110(a)(2)(C), (D), (J) and (K) of 

the Act and will be addressed in a 

subsequent rulemaking. 

Section 110(l) of the Act prohibits 

EPA from approving any SIP revision 

that would interfere with any applicable 

requirement concerning attainment and 

reasonable further progress (RFP) or any 

other applicable requirement of the Act. 

All of the elements of the infrastructure 

SIP that we are approving, as explained 

in the TSD, improve the SIP by 

replacing obsolete statutes or 

regulations and by updating the state 

and local agencies’ SIP implementation 

and enforcement authorities. We have 

determined that our approval of the 

elements discussed above complies with 

CAA section 110(l) because the SIP 

revision would not interfere with the 

on-going process for ensuring that 

requirements for RFP and attainment of 

the NAAQS are met, and the SIP 

revision clarifies and updates the SIP. 

Our TSD contains a more detailed 

discussion of our evaluation. 

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 the 

Arizona Regulations described in the 

amendments to 40 CFR part 52 set forth 

below. 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 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, EPA’s role is to approve 

state choices, provided that they meet 

the criteria of the Clean Air Act. 

Accordingly, this action merely 

proposes to approve 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 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 Clean Air Act; 

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). 

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).

Approval and Promulgation of State 

Implementation Plans; State of

NAAQS 

AGENCY: Environmental Protection 

Agency (EPA). 

ACTION: Final rule. 

SUMMARY: The Environmental Protection 

Agency (EPA) is approving a May 11, 

2012 State Implementation Plan (SIP) 

submission from the State of Colorado 

that is intended to demonstrate that its 

SIP meets certain interstate transport 

requirements of the Clean Air Act (Act 

or CAA) for the 2006 fine particulate 

matter (PM2.5) National Ambient Air 

Quality Standards (NAAQS). This 

submission addresses the requirement 

that Colorado’s SIP contain adequate 

provisions prohibiting air emissions that 

will have certain adverse air quality 

effects in other states. EPA is 

determining that Colorado’s existing SIP 

contains adequate provisions to ensure 

that air emissions in Colorado do not 

significantly contribute to 

nonattainment or interfere with 

maintenance of the 2006 24-hour PM2.5

NAAQS in any other state, or interfere 

with another state’s measures to prevent 

significant deterioration of air quality or 

to protect visibility. EPA is also 

approving the portion of Colorado’s 

submission that addresses the CAA 

requirement that SIPs contain adequate 

provisions related to interstate and 

international pollution abatement. 

DATES: This final rule is effective on 

September 9, 2015.
