Air Quality Standards,
and 1997 8-hour Ozone National Ambient
Air Quality Standards (September 2009)

as
a revision

to the Arizona State Implementation

Plan (SIP).V Clean Air Act (CAA) Section

1 10(a)(1) requires states

to submit SIPs within three years following

the promulgation

of new
or revised National Ambient
Air Quality Standards (NAAQS)

to provide
for implementation, maintenance,

and enforcement

of such standards. Each of these SIPs must address certain basic elements

or the “infrastructure”

of its air quality management programs under CAA Section

1 10(a)(2) including provisions

for monitoring, emissions inventories,

and modeling designed

to assure attainment

and maintenance

of the NAAQS. EPA promulgated revised NAAQS

for PM 2 . 5 , effective December

18, 2006 (71 FR 61144, October

17, 2006), which requires states

to submit Section 110(a)(2) SIPs by September

21, 2009. This SIP revision demonstrates

that Arizona State and local air quality management programs meet the basic program elements required under CAA Sections

1 10(a)(I) and (2) (with the exception

of Section

11 0(a)(2)(G))

for implementing

the 2006 PM 2 . 5 NAAQS. The analyses
and information contained

in this submission

also fulfills outstanding obligations under CAA Sections

ANALYSIS

OF CLEAN AiR ACT SECTION ll0(a)(2) AIR QUALITY CONTROL PROGRAM ELEMENTS
FOR ARIZONA Arizona Revised Statutes, Title 49, “Environment,” divides responsibility

and encourages cooperation

for meeting

the requirements

of the CAA among
the State, county agencies,
and regional planning organizations. Currently

the State and three county agencies operate

air quality control programs under direct

or delegated authority. These

air pollution control agencies

are: Arizona Department

of Environmental Quality (ADEQ), Maricopa County Air Quality Department (MCAQD), Pima County Department

of Environmental Quality (PDEQ),
and the Pinal County Air Quality Control District (PCAQCD). Figure

1 is a map showing Arizona coutities with air quality control agencies. The Arizona Department

of Environmental Quality
has primaiy responsibility

for air pollution control and abatement,

and
as such,

is required

to “maintain

a state implementation

plan that provides

for implementation, maintenance

and enforcement

of national ambient

air quality standards
and protection

of visibility

as required

by the clean air act” (ARS §49-404). ADEQ

is also responsible

for coordinating, along with local officials,

the development, adoption,
and enforcement

of control measures
and permits where
no local air quality control agency exists.

In addition, ADEQ has original jurisdiction

in all areas of the State for certain stationary

and portable,
and all mobile sources, including petroleum refmeries, coal fired electrical generating stations,
and the motor vehicle emissions inspection program (ARS §49- 402). Except
for the sources noted above, the county agencies have original jurisdiction

for the issuance, administration,

and enforcement

of permits (ARS §49-402).
The State may, however, assert jurisdiction where the local agency

is unable

to fulfill any function

or duty
as required. State law also provides direct county authority

to adopt and enforce programs, rules, and ordinances

for the prevention, control and abatement

of air pollution (ARS Title 49, Chapter

3, Article

3). Two metropolitan planning organizations,

the Maricopa Association

of Governments (MAG)
and the Pima Association

of Governments (PAG),

are certified

for the development

of nonattainment

and maintenance

area plans within their respective jurisdictions
(ARS §49-406). MAG and PAG submit their plans

to ADEQ
for adoption
and inclusion

in the state implementation

plan pursuant

to ARS §49-406.H. The following sections summarize

the requirements

of CAA Sections

11 0(a)(2)(A) through
(M) and present information

that demonstrates Arizona’s State and local air pollution control programs,

and commitments

to update emergency episode provisions, meet these basic elements
and are adequate

to ensure attainment

and maintenance

of the particulate matter and ozone NAAQS. ADEQ

is submitting ARS §49-455 [except Section (B)( 1)1 to address CAA section

11 0(a)(2)(E)(i)

and Title 38, Chapter

3, Article

8 to address CAA section

1 l0(a)(2)(E)(ii)

for inclusion

in the SIP. All other listed statutes and rules

in Sections

2.1 through 2.13 are for informational purposes only. Final CAA 110(a) SIP 090915

62.1 CAA Section 11O(a)(2)(A) —control Measures
and Emission Limits Section

11 0(a)(2)(A) requires SIPs

to include enforceable emission limitations

and other control measures, means,

or techniques,

as well

as schedules

for compliance necessary

to meet applicable requirements

of the CAA. The timing

of submittals

for specific nonattainment

area control measures
and plans

is subject

to the requirements

of CAA, Title

1, Part D, “Plan Requirements

for Nonattainment Areas;” therefore,

the demonstration

of compliance
with CAA Section

1 10(a)(2)(A) includes

the necessary authority

for State and local air quality management programs

to adopt and implement control measures
and plans

to assure attainment

and maintenance

of the PM 2 , 5 and 8-hour ozone
air quality standards

in all areas of Arizona. Relevant sections

Air Quality Monitoring Section

11 0(a)(2)(B) requires SIPs
to include provisions

for establishment

and operation

of ambient

air quality monitors,

to compile
and analyze ambient

air quality data, and make these data available

to EPA upon request. Arizona maintains

an extensive monitoring network operated

by State and county agencies designed

to collect, compile,
and analyze ambient

air quality data
in attainment

and nonattainment

areas of the State. Operating agencies track data recovery, quality control and quality assurance parameters

for all instruments operated

at various network sites. Criteria pollutant concentrations,

such

as PM and ozone, are measured with instruments meeting EPA certification

as Federal Reference

or Equivalent Methods. All data collected within
the PM and ozone compliance networks

are compared

to the NAAQS, statistically analyzed

for trends, and recorded quarterly

in EPA’s Air Quality System. Per Code
of Federal Regulations (CFR), Title 40, Part
58 the State and county agencies (ADEQ, MCAQD, PDEQ, and PCAQCD) annually submit

to EPA network monitoring plans. These plans identif’
the purpose

of each monitor and provide evidence that both the siting and the operation

of each monitor meets the network design, quality assurance,

and other federal requirements

of 40 CFR Part 58. Final CAA 110(a) SIP 090915

7The results

of air quality monitoring conducted throughout Arizona, including ambient PM and ozone data,

are contained

in ADEQ’s

Air Quality Annual Reports available

at http://www.azdeq.gov/functionlforms/reports.html.

The 2008 Report included ambient data from

15 PM 2 , 5 monitoring
sites and 39 8-hour ozone monitoring
sites throughout Arizona. Relevant sections

of supervisors 2.3 CAA Section 11O(a)(2)(C)— Enforcement

of Control Measures Section
110 (a)(2)(C) requires states

to include

a program providing

for enforcement

of all SIP measures and the regulation

of construction

of new or modified stationary sources

to meet prevention

of significant deterioration

(P SD) and nonattainment

new source review (NSR) permitting requirements. Arizona State and local agencies implement control and enforcement programs

for permitted sources

of air contaminants

and those sources that are not regulated through permits programs (open uncontrolled burns, construction, vacant land, etc.).
As part of the SiP enforcement program, ADEQ and local agencies track
all committed

SIP control measures

and work with the entities responsible

for those measures

to provide any needed assistance

and ensure timely implementation. Arizona Revised Statutes §49-406 provides additional assurance
that PM and ozone nonattainment

and maintenance measures
will be implemented

and enforced. Each agency that commits

to implement

any emission limitation

or other control measure contained

in the SIP
is required

to specif’,

in
a resolution adopted

by the governing body of the agency,

its authority

for implementing

the measure
and

a program
for enforcement

of the limitation or measure.

If any agency

or entity fails
to implement

a committed measure,

the county

is authorized

to file an action

in superior court for injunction

or any other relief provided

by law. Similarly,

if the county fails
to ensure implementation

of measures,

the ADEQ Director

is authorized, through
the State Attorney General,

to seek relief provided

by law to ensure implementation

of all measures. Arizona Revised Statutes Title 49, Chapter

3, Articles

1, 2, and

3 establish ADEQ and local agency authority

for preconstruction review and permitting. Under the air permits program, sources that emit regulated pollutants

are required

to obtain

a permit before constructing, changing, replacing,

or operating any equipment

or process which may cause air pollution.
This includes equipment designed

to reduce
air pollution. Permits
are also required

if an existing facility that causes
air pollution transfers ownership, relocates,

or otherwise changes operations. ADEQ and county permitting agencies operate

air quality permit compliance programs

to ensure implementation

of emission limits and other control measures

for permitted sources. These programs include scheduled

and unscheduled inspections conducted

at major sources annually

as well

as compliance assistance initiatives. Permit and SIP enforcement authority

is also provided

in ARS §49- 460 through 464, and 49-510 through 514, under which the State
or county may issue orders
of abatement,

and, through
the Attorney General

or County Attorney,
seek injunctive relief for any Final CAA 110(a) SIP 090915

1 10(a)(2)(H) requires states

to have authority

to revise their SIPs
in response

to changes

in the NAAQS

or availability

of improved methods

for attaining

the NAAQS. This Section also requires states to provide
for plan revisions

to ensure the adequacy

of the plan
to attain the air quality standards

or to otherwise comply with any additional requirements established under the Clean Air Act. Arizona Revised Statutes contain authority

to revise the Arizona
SIP to comply with the requirements

of the CAA including changes

in the NAAQS. Under ARS §49-404, ADEQ

is required

to “maintain

a state implementation

plan that provides

for implementation, maintenance

and enforcement

of national ambient air quality standards
and protection

of visibility

as required

by the clean air act.” Relevant sections

of Arizona Revised Statutes: 49-404. State implementation

D Nonattainment

Area Requirements Section

1 10(a)(2)(I) requires nonattainnient

area plans

to meet the applicable requirements

of CAA Title 1, Part
D relating

to nonattainment
areas. EPA’s October

2, 2007, guidance
(see Appendix

A) notes that “the speóific nonattainment

area plan requirements

of section

11 0(a)(2)(1)

are subject

to the timing requirement

of section 172, not the timing requirement

of section

11 0(a)(
1), and also that SIPs
to meet this section
are not covered

by the Consent Decree.” Although

the guidance

is intended

for the 1997 PM 2 . 5 and 8-hour ozone NAAQS, requirements for the 2006 PM 2 . 5 NAAQS under Section

1 10(a)(2)(I)

are the same. 2.10 CAA Section

1 1O(a)(2)(J)— Consultation
with Government Officials, Public Notification,

PSD and Visibility Protection Section

11 0(a)(2)(J) requires states
to: (1) provide

a process
for consultation
with local governments

and Federal Land Managers carrying

out NAAQS implementation requirements pursuant

to Section

121 relating

to consultation,

(2) notify the public

if NAAQS

are exceeded

in an area and to enhance public awareness

of measures
that can be taken

to prevent exceedances

per Section
127 relating

to public notification,

and (3) meet applicable requirements

of Part

C related

to prevention

of significant deterioration

of air quality and visibility protection. Arizona agencies maintain appropriate consultation procedures
with local governments,
CAA Section
174 and metropolitan planning agencies,

and federal land managers regarding implementation

of CAA requirements.

ARS §49-406 requires
the State, the metropolitan planning agency

on behalf

of affected local governments, county agencies,
and the Department

of Transportation

to enter into

a memorandum

of agreement

for the purpose

of coordinating

the development, implementation,

and enforcement

of nonattainment

and maintenance plans. Additionally, opportunity

for comment

is provided through stakeholder meetings
and public hearings held
to solicit testimony from the public

as well
as federal and local air quality planning agencies prior
to adoption

of any revision

to the Arizona SIP. Final CAA 110(a) SIP 090915

1, Part

C includes provisions relating

to prevention

of significant deterioration

of air quality and visibility protection.
PSD provisions

are discussed

in Section
2.3 above. Arizona’s visibility protection program

is designed

to analyze
the causes
of visibility impairment

and to develop
and implement control strategies

as required. Requirements include analysis

of emissions from new major sources

or sources making major modifications

and anticipated impacts

on visibility

at any Class

1 area. Arizona submitted

a Regional Haze SIP under
40 CFR 51.309

in December 2003, and

a 2004 revision

for its four Class

I areas on the Colorado Plateau.

is in the process

of preparing

a revision

to the SIP to meet the remaining requirement

of CAA Section

1 10(a)(2)(G) relating

to emergency episodes

for the 1997 PM 2 . 5 and 8-hour ozone NAAQS
and the 2006 PM 25 NAAQS. Clean Air Act Section

1 10(a)(2)(G) requires states

to provide
for authority

to address activities causing imminent
and substantial endangerment

to public health, including contingency plans

to implement

the emergency episode provisions

in their SIPs. Arizona Revised Statutes §49-465 authorizes State actions

to alleviate

or prevent

an emergency health risk to the public due to air pollution

or likely exceedance

of the NAAQS. Arizona Administrative

Code R18-2-220,

“Air Pollution Emergency Episodes,” which prescribes procedures

to prevent
the occurrence

of ambient

air pollution concentrations which would cause significant hann

to public health

is currently being revised

to incorporate

the most recent PM and ozone
air quality standards.

The revised “Emergency Episode” program
will be submitted

to EPA for approval

as
a component

of the SIP upon completion

of the State rulemaking

and public review process. Final CAA 110(a) SIP 090915

174.0 CONCLUSION This revision

to the Arizona
SIP demonstrates

that, with the exception

of

1 10(a)(2)(G),

the existing authorities

and infrastructure

of Arizona State and local air quality management programs,

in conjunction with the federal PSD program, meet the basic program elements required under CAA Section

1 10(aX 2 ) for the 2006 PM 2 . 5 NAAQS. This SIP revision also demonstrates

that outstanding requirements under Sections 110(a)(2)(E)(i)

and (E)(ii) for the 1997 PM 25 NAAQS
and Sections

1 10(a)(2)(A) through (M) for the 1997 8-hour ozone NAAQS

are met (see the U.S. Environmental Protection Agencys “Completeness Findings”

at 73 FR 62902; October

22, 2008, and 73 FR 16205; March
27, 2008). Final CAA 110(a) S1P 090915
