of Arizona Revised Statutes §49-104 and §49-404 (Enclosure

1) and the Code of Federal Regulations (CFR) Title 40, §51.102 through §51.104, the Arizona Department
of Environmental Quality (ADEQ) hereby adopts and submits
to the U.S. Environmental Protection Agency (EPA) the “Update of the Limited Maintenance Plan for the Payson PM 10 Maintenance Area” as a revision
to the Arizona State Implementation Plan (SIP). Under Clean Air Act (CAA) Sec.

1 75A(b),
“8 years after redesignation

of any area as an attainment area under section 107(d), the State shall submit to the Administrator

an additional revision of the applicable State implementation plan for maintaining the national primary ambient air quality standard for 10 years after the expiration
of the 10-year period referred
to in subsection (a).” This SIP updates the 2002 Payson Moderate Area PM, 0 Maintenance Plan and Request for Redesignation

to Attainment, providing for the maintenance

of the national primary ambient air quality standard for the years 2012 through 2022. The original attainment demonstration
and maintenance plan submission relied on federal New Source Performance Standards (NSPS) for residential wood heaters (40 CFR 60 subpart AAA) and completed local paving activities

to demonstrate maintenance

of the National Ambient Air Quality Standard (NAAQS)

in the area. No ADEQ promulgated rules were relied on to demonstrate attainment and maintenance
for the area. This update includes no new request for additional federally enforceable rules or standards. Reference

to the following local ordinances, state rules, and other strategies are submitted

as supplemental information and not for incorporation into the Arizona Applicable SIP: -Section 3.2.2., Industrial Sources— Table 3.1, Payson Permitted Sources and Reported 2008 PM 10 Emissions, and -Section 5.1.2., Supplemental Control Measures This update does include notice of early implementation

of a contingency measure.

lii 2004, Arizona promulgated changes
to Ri 8-2-702(B). The rule, however, was not
a measure that was relied on to Southern Regional Office 400 West Congress Street

or maintenance, and the rule change was not driven by a contingency measure implementation trigger. Ri 8-2-702, General Provisions, was incorporated

by reference by EPA in 2004 (69 FR 51952). With this submission, ADEQ requests that EPA approve this demonstration

of continued maintenance

of the National Ambient Air Quality Standard (NAAQS)

in the Payson PM 10 Maintenance Area. Enclosure

is a small Arizona community
of about 17,000 residents ninety miles northeast
of Phoenix. The area is a known travel destination because of its distinct western character, multitude
of outdoor activities and pleasant climate.
In 1993 EPA designated the area

a moderate nonattainment area for the PM 10 National Ambient Air Quality Standard (NAAQS) due to 11 recorded exceedances

of the 24-hour NAAQS for PM 10 at area monitors.

In response

to the designation, the Arizona Department

of Environmental Quality (ADEQ) submitted

a State Implementation Plan (SIP) projecting attainment
of the PM 10 NAAQS by 2001 with the implementation

of control measures. Following

a three-year period when there were no measured exceedances

of the NAAQS (1998-2000), ADEQ submitted

to EPA the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment. The plan was approved

in 2002, resulting

in a redesignation

to attainment for the PM 10 standard and qualification
for a Limited Maintenance Plan (LMP) option for continued reporting and planning requirements. Annual reports have been filed under the LMP option for the area for the years 2003 through 2009. Pursuant
to the Clean Air Act (CAA) Sec.

1 75A(b), “8 years after redesignation

of any area as an attainment area under section 107(d), the State shall submit to the Administrator

an additional revision of the applicable State implementation plan for maintaining
the national primary ambient air quality standard for 10 years after the expiration
of the 10-year period referred
to in subsection (a).” This SIP updates the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment, providing for the maintenance

of the national primary ambient air quality standard for the years 2012 through 2022, consistent with the provisions
of CAA Sec. 175A(b). Analyses demonstrate that ambient air quality measurements have remained below the NAAQS for PM 10 , the 24-hour average design value remains below EPA’s LMP eligibility threshold, and there

is likely continued achievement

of eligibility criteria based on area motor vehicle growth projections. This document also demonstrates that the emission reduction control measures primarily responsible
for the air quality improvement
are both permanent and enforceable. These control measures include reasonably available control measures (RACM)

to reduce fugitive dust emissions and measures

to reduce residential wood combustion emissions. The document also includes

a brief discussion

of the PM 10 regulatory history of the Payson area,

a description
of the community and maintenance area, an updated emissions inventory, demonstration

of continued LMP eligibility and regulatory commitments. ADEQ will continue to provide EPA with annual monitoring reports as outlined under the LMP option for the second ten-year period under the maintenance plan, 2012-2022.

1(ThisPageIntentionallyLeftBlank)1.0. REGULATORY HISTORY The Town of Payson

is a small community about ninety miles northeast of Phoenix that exhibits

a climate and community that is distinct from its much larger neighbor.

In addition
to a nearby casino for recreation, the area is known for an availability
of extensive outdoor activities,

a distinct western appeal, small community cultural events (e.g. rodeos and festivals) and the arts. A unique community, the Town of Payson thrives as both

a retirement and travel destination.

A map of the Town of Payson detailing land ownership type is provided below (Figure 1.1). As a small community, there are no significant sources of air pollution

in the area and the town generally experiences

a healthy air climate; however, prior to the implementation

of EPA wood burning stove new source performance standards

in 1988 and Town adoption of ordinances

to mandate the cleaner burning stoves, cold winter nights lead to significant use of wood burning stoves and fireplaces. These wood burning stoves and fireplaces led to elevated PM 10 concentrations

in the area above the Clean Air Act (CAA) prescribed standard for the pollutant.’ The air quality issues experienced

by the Town were further compounded

by other sources including unpaved roads and parking lots and industrial facilities. On eleven days in 1989 and 1990, air quality monitors located
in the Payson, Arizona PM 10 planning area recorded exceedances
of the 24-hour PM, 0 NAAQS (Table 1.1). On December 21, 1993, EPA designated the central portion of Gila County that includes the community

of Payson
as a moderate PM 10 nonattainment area, effective January 20, 1994 (58 FR 67334). As a result of this action, the State was required
to submit
to EPA

a PM, 0 State Implementation Plan (SIP) which included
an attainment demonstration
for the area. The notation PM 10 refers to particulate matter 10 micrometers

in diameter
or less (or about one-seventh
the width of a human hair) and raises health concerns such as respiratory problems, lung damage, cancer, and premature death at unhealthy exposure levels. For more information about PM 10 , please see http:!/wwwepa.gov/air/particlepol

287 In June 1995, the Arizona Department
of Environmental Quality (ADEQ) submitted

to EPA the PM 10 State Implementation Plan for the Payson PM 10 Nonattainment Area. The SIP contained air quality modeling for the design year 1990 and projected attainment

in the year 2001 based on emission reductions from certain PM 10 sources (such as unpaved roads and parking lots). The 1990 base year emissions inventory

is comprised
of PM 10 emissions from paved and unpaved roads, wood smoke, and industrial sources. The attainment demonstration was based upon the impact of implemented Reasonably Available Control Measures (RACM) that reduced PM 10 emissions generated from the identified source categories, the closure of two industrial sources, and more stringent EPA standards for woodstoves
(A more detailed discussion
of air quality for the Payson Maintenance Area is included

in Section 3.0, Air Quality and Emissions Inventory). The demonstration also took into account the increases
or decreases

in PM 10 that would result from changing land use patterns and the growth
in population and vehicle traffic between 1990 and 2001 in the Payson area. PM 10 concentrations reported

at the Payson monitoring site between 1998 and 2000 showed no measured exceedance
of the 24-hour PM 10 NAAQS. The three-year average was less than one exceedance per year, which indicated the Payson area attained the 24-hour PM 10 NAAQS. As
a result, EPA redesignated
the Payson PM 10 planning area from nonattainment

to attainment, effective August 26, 2002 (67 FR 43013). Included

in the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment was an assessment and demonstration

of the Payson area eligibility for the 2 PM 10 State Implementation Plan for the Payson Nonattainment Area, ADEQ, June 1995. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

2Limited Maintenance Plan (LMP) option. The LMP option allows for a streamlined alternative

to the reporting required under

a Maintenance Plan 3 . The streamlined reports filed under the LMP option (or annual maintenance demonstrations)

for the Payson PM 10 Planning Area were submitted for the years 2003 through 2009. These reports originally included information for both the 24-hour and annual PM 10 standards; however,
on October 17, 2006 EPA revoked the annual PM 10 standard
in a final rulemaking
(71 FR 61202). Consequently,
the 2006 emissions year was the last reported annual PM 10 data (submitted June 2007). All subsequent reports submitted
by ADEQ have shown the applicable reporting for attainment
of the 24-hour PM 10 NAAQS and the Payson PM 10 planning area 24-hour design value criteria reporting required for LMPs (the method for calculating design values for PM 10 is detailed
in PM 10 SIP Development Guideline, EPA-45012-86-001,
June 1987). Annual maintenance demonstrations

for the 24-hour PM 10 NAAQS will continue
to be filed as required through the maintenance period, ending in 2022. August 21, 2001 Wegman Memorandum: Limited Maintenance Plan Option for Moderate PM 10 Nonattainment Areas Final Update to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

32.0. PAYSON PM 10 MAINTENANCE AREA 2.1. Location The Town of Payson was incorporated

in 1973 and is located
in northwestern Gila County, approximately

90 miles northeast of the Phoenix metropolitan area. At 5,000 feet in elevation, the area has
a moderate climate; classified

as semiarid mesothermal 4 . The community draws visitors with its rich western heritage
in addition
to serving
as a mountain recreation gateway
to the Mogollon Rim. The Payson maintenance area contains four complete townships and is 144 square miles in size (40 CFR



# § 81.303). The Town of Payson

is approximately

in the center of the geographic area covered. The Payson maintenance area is defined by the following townships (see Figure 2.1): T1ON, R9E, sections 1-3, 10-15, 22-27, and 34-36 T11N, R9E, sections 1-3, 10-15, 22-27, and 34-36 Tb-i IN, RIOE T1ON, Ri 1E, sections 4-9, 16-21, and 28-33 T11N, RilE, sections 4-9, 16-21, and 28-33 2.2. Monitoring Network Ambient concentrations

of both Total Suspended Particulates (TSP) and PM 10 have been measured

in Payson since 1974. Ambient concentrations

of TSP were measured from 1974 to 1987. In July 1987, ADEQ began monitoring ambient concentrations

of PM 10 . Initially, the ambient particulate monitor was located
in downtown Payson from 1974 to 1977. The particulate monitor was moved to the Tonto National Forest Ranger Station
in 1977 and operated
at that site until 1980. Recorded PM levels at the Tonto Ranger Station were much lower than the recorded levels at the Payson downtown site, due to its location two miles north of downtown Payson. The new site was not subject
to the same urban particulate sources and influences

as the downtown site. As a result, in 1980, the Tonto Ranger Station monitor was relocated
to the Gila County Sheriff’s office at 108 West Main Street. In June 1991,

a new roof was added to the Sheriff’s office, making

it necessary

to move the PM 10 monitor
to a new location.
In July 1991, the PM 10 monitor was relocated approximately 0.25 miles west to the roof of the single story US West building

at 300 West Main Street. In January 1999, sampling

at the US West building was concluded and the PM 10 monitor was relocated

to 204 W. Aero Drive (the Payson water treatment plant), approximately
one mile southeast of the US West site. It is the intent of ADEQ
to operate the Payson PM 10 monitor through tile maintenance period, ending
in 2022. The site is operated on a once everysixthday sampling period. The location, method, and parameters measured are detailed below. Table 2.1 Monitoring Network Began

52.3. Population In the 1970s, during which rural counties

in the U.S. outpaced urban counties

in population growth, the population
of Payson increased nearly three-fold. The population boom in Payson resulted
in growth of more than 180 percent between 1970 and 1980. At the same time, Gila County grew at a moderate rate of 26.7 percent. Payson continued

to gain population during the 1980s and 1990s at a rate exceeding
60 percent.
In contrast, Gila County’s growth rate was 8.5 percent during the 1980s and increased

to a relatively moderate 27.7 percent during the 1990s. Decennial census data for Payson and Gila County are shown in Table 2.2. As evidenced

in the 2010 census data, the populations
of Payson and Gila County have continued

to grow. Table 2.3 shows Arizona Department
of Commerce estimates of the population
of the town and county from the period 2002 to 2008. The population

in the area is projected

to continue growing, albeit at a lower rate than historical levels. Table 2.4 includes Arizona Department
of Commerce population projections for both the Town of Payson and Gila County for the years 2015 through 2025. Table 2.2 Decennial Census Population

Rixis 2.3. Economics Economic activity
in Gila County can be described

as divided between mining activities

in the south and tourism
in the north where Payson

is located. Since Payson

is a recreational and retirement community, retail trade and various service industries play an important role in the local economy. Because of the popularity
of this area, permanent residents and tourists have increased demand for lodging, restaurants, and various businesses related to tourism, including retail. 5 The economic industry base for the region has not changed significantly since the 2002 Payson PM 10 Limited Maintenance Plan was submitted; the area continues

to serve predominantly

as a retiree community with significant tourism. According

to a 2008 report prepared by the Arizona Department
of Commerce, Economy of Payson and Star Valley, 6 overall employment levels in various sectors of the economy are lower than in comparable communities due, in part, to the relatively large proportion
of seasonal residents and retirees. The report indicates the senior citizen portion of the population

is double state and national averages and that the proportion
of seasonal housing units is higher than average
as well. Major employment sectors include government, health care, lodging and entertainment. The Payson Unified School District, Gila County, the Mazatzal Casino of the Tonto Apache Tribe, and the Payson Regional Medical Center are some of the area’s largest employers. Tables 2.5 and 2.6 show selected time series of civilian labor force data both before the Payson area attainment designation and for the period following that designation. The unemployment rate fell to a low of 2.8% in 2000 and generally averaged between 3-5% until the later part of the decade.
In 2008 the unemployment rate for the Town of Payson rose to 6.2% due to nation-wide recession conditions and has continued

to remain above recent historical norms. The increased unemployment rate for the area has not resulted
in an associated population exodus, and it is anticipated that the unemployment rate will return to historical levels as national, state, and local economic conditions recover. 5 According

to Arizona Department
of Revenue, taxable sales in Gila County have increased from $220,271,939

in fiscal year 1999-2000,

to a high of $308,440,601
for fiscal year 2007-08.
In fiscal year 2008-09, taxable revenues fell to $276,550,207

a decrease of approximately
10% over the previous year. Recent Arizona Department

of Revenue Annual Reports are available

83.0. AIR QUALITY

& EMISSIONS INVENTORY 3.1. Air Quality Data for the 24-hour Standard Since 1991, the Payson area 24-hour PM 10 design value (DV) levels, based on the high 24-hour ambient concentration

in a year, have been in compliance with the NAAQS. This is due primarily
to the 1988 implementation

of more stringent EPA New Source Performance Standards (NSPS) for residential wood heaters (40 CFR 60 subpart AAA), but also is related
to measures

to control fugitive PM 10 emissions generated from identified source categories, including completed paving activities, the closure of two industrial sources
in 1993, and other control measures. Further, from the time of the submission
of the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment, and over the course of the maintenance period to date, observed ambient concentrations
and calculated design values (required

in annual reporting) were significantly below the NAAQS, 150 jig/rn 3 . Whereas compliance with the NAAQS

is evaluated based on the recorded high PM 10 concentration events over the course of a year, the emissions inventory establishes
an emissions profile of an average day based on the annual emissions for identified source categories. There are some differences in the proportional contribution
of various source categories derived
in this inventory when compared

to previous analyses. This
is due in part to area growth and development, changing technologies, implemented control measures,

as well as the improvement

of assessment methodologies
and technical tools since previous submittals. The following sections
in this chapter provide

a discussion
of the methodology used to update the emissions inventory for the area from identified contributing source categories and
a presentation

of the derived inventory. 3.2. Emissions Inventory— Methodology The LMP option requires an update of the emissions inventory along with the demonstration

of continued eligibility through the end of the maintenance period,
in this case the year 2022, through an analysis of potential motor vehicle emissions growth. The emissions inventory

is used to determine the factors used in this growth analysis (see Section 4.1, LMP Option Eligibility). The following emissions inventory updates the Limited Maintenance Plan for the Payson Maintenance Area in part with data from the 2008 National Emissions Inventory (NET); for mobile and industrial source categories, localized data with greater specificity was used to determine source contribution levels. The methodology used to determine contribution

of the various sources

is largely the same as conducted

in 2002, except for the motor vehicle portions of the inventory. The on-road emissions were updated using

a combination

of Arizona Department
of Transportation’s Highway Performance Monitoring System (HPMS) traffic counts data (for 2007) and the generation
of spatially explicit local paved and unpaved roads data. The source categories used in the emissions inventory are the same as previously identified

in the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment. These categories include: • residential wood combustion

• unpaved roads— fugitive dust • construction activities

• paved roads— fugitive dust • industrial sources

• paved roads— exhaust • reentrained dust

• brake and tire wear Final Update to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

93.2.1. Residential Wood Combustion and Construction Activities For the Construction Activities and Residential Wood Combustion emissions categories, ADEQ used the same methodology conducted for the 2002 Payson Moderate Area PM, 0 Maintenance Plan and Request for Redesignation

to Attainment. The county-wide emissions reported
in the 2008 NEI, the most recent EPA certified emissions data available, were adjusted
to the Payson Area using the population ratio of the Town of Payson
to that of Gila County
as a metric for scaling county level emissions

to the Maintenance Area (using the April

1, 2008, population estimates, Table 2.3). Population adjustments: 2008 Payson Area Population

= 16,965 2008 Gila County Population 57,361 Adjustment Ratio, 16,965/57,36

1 0.296 (0.3) Construction Activities The NET reported

a total of 375 tons of PM 10 per year from construction activities

in the County during 2008. Based on the population scaling ratio, PM 10 emissions from construction

in the Payson PM 10 Non-Attainment Area were estimated

to be 112.5 tons per year. Residential Wood Combustion The NET reported

a total of 53 tons per year from residential wood burning
in the County
in 2008. Based on the population scaling ratio, PM 10 emissions from residential wood burning
in the Payson PM 10 Non-Attainment Area were estimated

to be 15.9 tons per year. 8 3.2.2. Industrial Sources 9 Industrial sources emissions data for 2008 were provided
to the department
by permitted sources in response
to an annual survey conducted
by ADEQ. Emissions

in this category totaled 2.54 tons per year; less than one percent of the 2008 emissions inventory (see Table 3.5.). The following table (Table 3.1) is a listing of all active permits
in the Payson Maintenance area and their reported annual emissions for 2008. Included
in the list of sources

is an identification

of state regulations incorporated into permits issued by ADEQ that acknowledge and control for PM 10 emissions from the facilities. Notably, the PM 10 emissions from permitted facilities

in the maintenance area are low and any potential new source development will require emission constraints consistent with the regulatory ranges appropriate for the maintenance area. 8 This figure represents

a significant reduction

in PM 10 emissions from residential wood combustion due to the implementation

of federal NSPS. The emissions attributed

to the source category have fallen from an estimated 158.8 metric tons in 1990 (1995, Final PM, 0 State Implementation Plan for the Payson Nonattainment Area to the current estimate of 15.9;

a 142.9 metric ton reduction

in the area. The identification

of state regulations for permitted facilities

to extract vehicle miles traveled (VMT) and PM 10 emissions from exhaust, tire, and brake wear for 2008 for Gila County, Arizona including
all twelve NMIM vehicle types. PM, 0 emissions factors were then back calculated from NMIM’s output. The result was one emissions factor per vehicle class per roadway functional classification. The classes were grouped into the two main categories:

11passenger vehicles, and 2) trucks; for which vehicle type mix data are available

in local annual average daily traffic (AADT) data (see Annual Average Daily Travel (AADT) and Vehicle Miles Traveled (VMT) discussion below). The Highway Performance Monitoring System (HPMS) Field Manual (Chapter

4: Universe and Sample Data Requirements, Items 82 and 8411) was followed for grouping vehicle classes into one of these two categories. ADEQ then averaged the emissions factors for each vehicle class in each roadway functional classification. Table 3.2 contains the PM, 0 exhaust and tire and brake wear emissions factors’ 2 . Reentrained Dust Unpaved Roads ADEQ used an emissions factor of 185.3 grams per mile, consistent with the previous LMP submittal.’ 3 While the AP-42 calculation for the emissions factor was updated
in 2006, there are not sufficient localized empirical data for recalculation; therefore, the same factor was used for the updated inventory. Paved Roads The EPA equation for reentrained dust emissions factors from paved roads in AP-42 was updated
in January 2011 (an approximate 67% decrease), after the submission
of the 2002 Payson LMP. The change
in the AP-42 emissions factor calculation reduced the emissions outcome for the identified source category

in the updated emissions inventory when compared

to previous iterations. Taking these changes into consideration, ADEQ derived paved roads reentrained fugitive dust emissions factors from AP-42 Volume

Final Update to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area 

# 13For consistency with the 2002 

# Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment, ADEQ used

a particle size multiplier



# k of 1, a silt loading 

# sL value of 0.2 g/m 2 , and an average vehicle weight W of 3.2 tons as was used in the previous LMP. Substituting the variables

in Equation (1), ADEQ obtained

a reentrained dust emissions factor of 0.7572 grams per mile. Table 3.3 shows the reentrained dust emissions factors for paved and unpaved roads. Table 3.3 PM 10 Fugitive Dust Emissions Factors Fugitive Dust Emissions Factor (gfmile) Unpaved roads

# AnnualAverage Daily Travel (AADT) and Vehicle Miles Traveled (VMY’) Activity levels for on-road PM 10 emissions were determined using the Arizona Department
of Transportation’s Highway Performance Monitoring System (ADOT-HPMS)

for 2007,

a geospatially-referenced database (“geodatabase”)

of publicly-maintained roads in Arizona. The geodatabase includes Annual Average Daily Traffic (AADT) counts on roadway segments 

# and sampling segment lengths
in miles for major and minor arterials (i.e., freeways, expressways) and major and minor collectors.

It does not, however, contain data on local roads. To address this limitation, ADEQ digitized local paved and unpaved roadway centerlines

in a geographic information system (GIS) using 2007 aerial photography from the USDA’s National Agriculture Imagery Program (NAIP),
at a cartographic scale of 1:2000. Lacking AADT counts for local roads, an assumed value of 10 AADT for these roads (paved and unpaved) was used. 15 In GIS, I-IPMS roadways within the Payson PM 10 Maintenance Area were extracted 

# and VMT calculated
by multiplying the AADT value in road segment by the segment’s length in miles. Figure 3.1 shows VMT both for HPMS and digitized local roads in 2007 in the Payson PM 10 Maintenance Area. 15 ADEQ studied the digitized unpaved roads for the Payson planning area and found

a total of 141 miles of unpaved roads. Based on the number of houses on an unpaved road, the AADT could range from 100 to 0. A rough estimate of the Vehicle Miles Traveled (VMT) on any section of unpaved road could range from

0 to 300. The sum of unpaved road VMT
is on the order of 1400 VMT, which results in estimated AADT of 10. The range of AADT

is in the same range found in the “Maricopa Five Percent Plan” (AADT range from
4 to 150). Final Update to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

15HPMS data also contain percent average daily single unit and combination trucks by roadway segment,
an indicator of vehicle class mix (see The I-IPMS Field Manual, Chapter

4: Universe and Sample Data Requirements, Items 82 and 8416). ADEQ used this information

to estimate the following for each roadway segment:

1) the fraction of VMT from trucks (defined
as the sum of fraction average daily single unit trucks and fraction average daily combination trucks); and 2) the fraction of VMT from passenger vehicles [one minus the calculation

in (1)]’. On-Road Emissions Calculation Summary ADEQ applied the emissions factors
in Table 3.2 to VMT in each roadway segment separately

to passenger vehicle and truck categories

to calculate PM 10 emissions from exhaust, tire, and brake wear. Because fugitive dust is not dependent
on vehicle type mix, ADEQ applied the fugitive dust emissions factor directly
to VMT to calculate these emissions. Table 3.4 summarizes VMT and fugitive dust and tire, exhaust and brake PM 10 vehicular emissions

in 2007 in the Payson PM 10 Non-Attainment Area. State Routes 87 and 260 are the main routes in Payson, and consequently, have the highest AADT values. The portions of both routes that cross through the town, however, are represented

in HPMS
as separate roadway segments classified

as Rural Major Collector, Rural and Urban Other Principal Arterial,
or Urban Minor Arterial. ADEQ summarized VMT and emissions for Arizona State Routes 87 and 260 separately,

to adequately characterize VMT and emissions

in all segments
of those two main roadways. For clarification,
the total VMT and emissions for Rural Major Collector, Rural and Urban Other Principal Arterial, and Urban Minor Arterial do not include segments of those roadway classifications that were part of State Routes 87 or 260.

LIMITED MA1TENANCE PLAN DEMONSTRATION 4.1. Limited Maintenance Plan (LMP) Option Eligibility To be eligible for the LMP Option, two criteria must be met. First, the PM, 0 design value (DV) for the area, based upon the most recent five years of air quality data at all monitors

in the area, should be at or below 98 j.tg/m 3 for the 24-hour PM 10 NAAQS with no violations

at any monitor
in the nonattainment area. If the DV exceeds the 98 jLg/m 3 limit, then the site-specific Critical Design Value (CDV) must be calculated (see Attachment

A of the LMP Option for Moderate PM 10 Nonattainment Areas memo).
If the DV is less than the CDV, the maintenance area also qualifies for the LMP option. Second, an area should expect only limited growth
in on-road motor vehicle PM 10 emissions (including fugitive dust) and should have passed

a motor vehicle regional emissions analysis test.’ 8 The analyses below show how both criteria for eligibility have been met. Based on the most recent five years of air quality data, 2006-2010, the 24-hour design value for the Payson area is 66 jig/rn 3 (Figure 4.1). This is well below the EPA LMP eligibility criteria of 98 jig/rn 3 for the 24-hour NAAQS and calculation
of the CDV
is not required. Further, during the time period there have been no violations
of the NAAQS. Figure 4.1 _+66

in Air Quality Not Due to Temporary Econornic Downturn
or Unusually Favorable Meteorology Data provided previously show significant population growth
in Payson between 1970 and 2008, see Tables 2.2 and 2.3, with continued growth expected into the future, see Table 2.4. While the local unernployment rate has varied sornewhat over time, total labor force data from 1990 through 2010 also demonstrates growth
in the area, see Tables 2.5 and 2.6. The recent decline
in growth rate and employment
for the area (corresponding

to a more widespread decline
in the economy starting
in 2008), however,

is not correlated

to the lower observed PM, 0 concentrations

in Payson. During the eight-year period during which the Limited Maintenance Plan has been in place the area has maintained levels below the PM, 0 LMP option eligibility threshold (98 jig/rn 3 ), regardless
of economic growth or contraction. The continued maintenance

of the PM, 0 NAAQS

is not due to the temporary economic downturn recently observed. Further,

a full range of meteorological conditions, both favorable and unfavorable, have been observed yet maintenance continues. 19 Based on a trend analysis of the most recent 10 years of HPMS data, ADEQ calculated
an increase
in VMT to be approximately 20,000,000 per year or 200,000,000 over
a 10 year period for Gila County. Based on an annual VMT of 840,000,000
for the county
in 2008
it represents
an increase of 23.8%. The same percentage (23.8%)

is applied for the Payson VMT growth projection. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

19The primary source of PM 10 emissions for the exceedance events in 1989 

# and 1990 was emissions from wood burning stoves on cold winter nights. With the implementation

of cleaner burning technologies, local ordinances

to support those technologies, and replacement programs, the area has addressed the issue. Growth
in the areas population 

# and traffic associated with PM 10 emissions were not responsible for the area’s initial emissions problem and designation, and are not projected

to change the attainment status in the analysis conducted

in this update. Final Update to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

205.0. CONTROL MEASURES 5.1. Reasonably Available Control Measures (RACM) In February
of 1988, EPA promulgated New Source Performance Standards (NSPS) for residential wood heaters. As stated previously, the implementation

of stricter controls on wood-burning stoves, the primary contributor

to historical exceedances

in the area, allowed the Payson area to achieve attainment
of the PM 10 NAAQS. Implemented RACM that reduced PM 10 emission generated from other identified source categories, including paving activities and other general measures, further reduced PM 10 emissions

in the area. Since existing industrial sources contribute less than one percent
to the total 2008 PM 10 emission estimates (Table 3.3), the RACT requirement does not apply to the Payson area with respect
to either primary
or secondary PM 10 emissions. PM 10 emissions from existing industrial sources
in the area are regulated under the ADEQ air permit program. Air quality permits are required for existing industrial sources and ensure adequate control of PM 10 emissions and contain PM 10 controls such as production

or discharge limits; maintenance and installation
of air pollution controls (e.g. baghouses, water sprays, enclosures, shrouds,
or scrubbers; and use of dust suppressants, soil stabilizers
or wetting agents on haul roads, storage piles, and parking areas). The Air Quality Permits that cover the industrial sources listed in Table 3.1 require annual reporting of compliance status with permit requirements

to ADEQ and allow for inspection
of the facilities
to ensure compliance. 5.1.1. SIP Incorporated Control Measures The following control measures were responsible for bringing the area into attainment and were approved by EPA in 200220: State of Arizona -ADOT installed

2 miles of curbs and gutters on Arizona State Highway
87 from the intersection of Highways
87 and 260 to Roundup Road in 1992. -ADOT installed

5 miles of paved shoulders on Highway
87 North and Highway 260 East when those stretches were widened
in 1992. -ADEQ issued

a rule, Arizona Administrative Code (A.A.C.) RI 8-2-607, that requires control of storage piles to minimize fugitive emissions. 21 The Town of Payson -The Town of Payson paved

4 miles of unpaved roads that were unpaved
in 1990. -EPA implemented New Source Performance Standards for woodstoves

in 1988. Gila County -Gila County paved nearly 18 miles of previously unpaved roads starting
in 1989. 2067 FR 4301321 R18-2-607 Storage Piles was submitted

to EPA as R9-3-407
on January
4, 1979, and subsequently approved by EPA on April 23, 1982 (47 FR 17485). The rule was renumbered

in 1993 to R18-2-607 and submitted

to EPA for incorporation into the Arizona Applicable SIP on July 15, 1998. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

215.1.2. Supplemental Control Measures The following control measures are supplemental PM 10 mitigation strategies included
in the 1995 PM 10 State Implementation Plan for the Payson PM 10 Nonattainment Area and 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment for which no emissions reduction credit was assumed: 22 The Town of Payson -The Town of Payson ensures the rapid response
to temporary sources of dust on paved roads (water erosion runoff, mud/dirt carry-out areas, material spills, skid control sand) by providing for traffic rerouting,
or clean up. -The Town of Payson requires the paving of commercial parking facilities under the Unified Development Code (UDC) section 15-04-002(D),
and the paving of unpaved roads as condition of minor land divisions, section 15060O4.23 -The effective implementation

of ordinances
by the Town of Payson (Chapter XV, Chapter 150.27, Installation
of Solid Fuel Burning Stoves 24 ) ensured that the benefits of the new EPA standards for woodstoves continue
to be achieved
in the area. Within the Town of Payson -A private flood control project located
in the area has been completed and is anticipated to reduce siltation on some roads. State of Arizona -ADOT specifications
for state contracts will include dust control plan requirements
for construction activities

in PM 10 nonattainment areas. -The State of Arizona implemented state income tax incentives for the costs of conversions
of wood fireplaces

to qualified wood stoves, fireplaces
or gas logs.

25 -In 2004, ADEQ rule A.A.C. R18-2-702(B) was updated
to require 20% opacity standards for areas in nonattainment

or maintenance areas for particulate matter standards. 26 The early implementation

of the contingency measure (area opacity standard revision from 40% to 20%) was not due to a contingency measure trigger. -Certified enhanced smoke management plan requirements
are implemented

by the Forest Service, Bureau of Land Management,
and Arizona Department
of State Lands,
in cooperation with ADEQ 27 . 22 The provided supplemental mitigation strategies are provided for informational purposes only and are not for approval into the Arizona Applicable SIP. 23 Both referenced UDC sections were adopted by Ordinance #446 February 22, 1996, updated June

by reference by EPA August 24, 2004 (69 FR 51952), effective September 23, 2004. 27 October
2, 2007 ADEQ provided
an “Enhanced Smoke Management Plan Certification” letter to Mr. Wayne Nastri of EPA outlining Arizona rules related to smoke management and regional haze. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

22These supplemental RACM controls contribute still further to fugitive dust emission reductions and public health protection. Continued implementation

of the measures will help ensure that the Payson area maintains the 24-hour PM 10 NAAQS. 5.2. Permanent and Enforceable Control Measures The CAA requires that each maintenance plan demonstrate that the measures that were credited with bringing the area into attainment are federally enforceable and continue

in the future. The original attainment demonstration and maintenance plan submission relied on federal New Source Performance Standards (NSPS) for residential wood heaters (40 CFR 60 subpart AAA); these standards are federally enforceable and permanent.. The paving identified

is fully constructed and permanent, and ADOT continues

to pave unpaved intersections

to the ADOT right-of-way during construction projects. Therefore, the Payson plan meets the CAA requirement
for permanent and enforceable control measures. 5.3. Contingency Measures Section

1 75A of the Act requires that
a maintenance plan include contingency provisions,

as necessary

to promptly correct any violation of the NAAQS which may occur after redesignation

of the area to attainment.

s memo, Limited Maintenance Plan Option for Moderate PM 10 Nonattainment Areas (Wegman, August
9, 2001), states that the contingency measures
do not have to be fully adopted, but should identify measures

to be promptly adopted,
if necessary. As previously noted, in 2004 the early implementation

of a 20% opacity standard occurred. Under the LMP option, the State is required
to calculate the design value for the area annually and determine

if the criteria of 98 .tg/m 3 for the 24-hour standard (or, alternatively,
the CDV) for the LMP option will still be met. If after performing the annual calculation, the State determines that the area has exceeded the LMP option limit, the State commits
to take action to attempt
to reduce PM 10 concentrations enough to remain qualified for the LMP option. Further, the State commits
to seek an expeditious remedy for any potential violation of the PM 10 NAAQS which may occur. Specifically,
the State commits
to determine whether
or not violations have been recorded within six months after the close of the calendar year, and to review and determine appropriate contingency measure(s)
by the end of the same calendar year. The State commits
to implement the selected contingency measure(s) within one year of determining that

a violation has occurred. Table 5-1 includes measures that will be considered for implementation

in the event of a violation of either the 24-hour NAAQS
or in the event the annual recalculation

of the area’s average design value exceeds the LMP option design value criteria. The cause of the violation
or exceedance
of the LMP option design value will help determine the appropriate contingency measure(s)

to be implemented. Final Update

# Table 5-1 Payson Area Contingency Measures Implementing Contingency Measures

Entity If any PM 10 industrial source operating within the maintenance area is found to be ADEQ contributing

to monitored readings above the limited maintenance plan allowable limits, ADEQ will review existing air quality permit(s)
to identify additional PM 10 control measures which may be needed. If the PM 10 source does not have

a permit, the permitting authority will determine

if an air quality permit and PM 10 controls are needed. If wood burning sources are found to be contributing

to monitored readings above the ADEQ limited maintenance plan allowable limits, ADEQ will review State regulations and programs

to determine appropriate action. Pave or stabilize public unpaved roads, vacant lots, or unpaved parking lots located
in Town of Payson andlor the PM 10 maintenance area subject to limits of statutory authority.

Gila County Continuation

of the Enhanced Smoke Management Plan- 

# state and federal land U.S. Forest Service, managers conducting prescribed burning must register with ADEQ for proposed
U.S. Bureau of Land burning activities (Arizona Administrative Code Ri 8-2-Article

on meteorological conditions) and may increase ADEQ. outreach and enforcement resources. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

246.0. REGULATORY COMMITMENTS Consistent with the March 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for Redesignation

to Attainment submittal, ADEQ reaffirms
to EPA the following commitments regarding air quality monitoring, control measures and maintenance

of an emissions inventory: 1. The State will continue
to operate an appropriate PM 10 air quality monitoring network
to verify the attainment status of the area in accordance with 40 CFR Part 58. The Payson monitoring network

is described

in Section 3.1 of this plan. 2. The control measures for the area, which were responsible
for bringing the area into attainment, were approved
by EPA as meeting reasonably available control measures (RACM) and reasonably available control technology (RACT) requirements,
are described

in Section 5.0 of this plan, and continue
in force throughout the maintenance period. 3. Submission
of Annual Reports
to EPA The ADEQ Air Quality Division will continue
to submit annual reports to EPA. These reports will include calculation
of the Payson Maintenance Area PM 10 design value to document and monitor the area’s air quality levels. Should the levels rise above the limits qualifying the area for the LMP, the State will act to lower them. Should the actions fail, the state will develop and submit

a full maintenance plan, as required under the LMP guidance. 4. Continued Maintenance and New Source Permitting Arizona Administrative Code (AAC) Ri 8-2-406, Permit Requirements for Sources Located in Attainment and Unclass/Iable Areas, applies for any major source or major modification to a source located within the maintenance area. Since the implementation

of the LMP in the Payson PM 10 Maintenance Area, monitoring data demonstrates
the area is controlling for PM 10 and, given the implemented control measures, ADEQ’s emission estimates predict the area will continue
to demonstrate maintenance

of the PM 10 NAAQS through 2022, the second ten years of the maintenance period. If there
is an unexpected increase
in PM 10 emissions

at some time during the remainder
of the maintenance period, contingency measures are in place to maintain compliance through the maintenance period. Final Update
to the Limited Maintenance Plan for the Payson PM 10 Maintenance Area

JOHN ENGLANDER:

In 1993, EPA designated the Payson area
a moderate nonattainment area 2 for the PM 10 National Ambient Air Quality Standard (NAAQS) due to eleven recorded exceedances 3 of the 24-hour NAAQS for PM 10 at area monitors.
In response
to the designation, the Arizona 4 Department
of Environmental Quality (ADEQ) submitted

a State Implementation Plan (SIP) 5 projecting attainment
of the PM 10 NAAQS by 2001 with the implementation

of control measures. 6 Following

a three year period when there were no measured exceedances
of the NAAQS (1998- 7 2000), in March of 2002 ADEQ submitted

to EPA the Payson Moderate rea PM 10 Maintenance 8 Plan and Request for Redesignation

to Attainment. The plan was approved
in 2002, resulting
in a 9 redesignation

to attainment for the PM 10 standard and qualification
for a Limited Maintenance Plan 10 (LMP) option for continued reporting and planning requirements. 11 12 Pursuant
to the Clean Air Act (CAA) Sec. 175A(b),
“8 years after redesignation

of any area as an 13 attainment area under section 107(d), the State shall submit
to the Administrator

an additional 14 revision of the applicable State implementation plan for maintaining the national primary ambient air 15 quality standard for 10 years after the expiration
of the 10-year period referred
to in subsection (a).” 16 This SIP updates the 2002 Payson Moderate Area PM 10 Maintenance Plan and Request for 17 Redesignation

to Attainment, providing for the maintenance

of the national primary ambient air 18 quality standard for the years 2012 through 2022, consistent with the provisions
of CAA Sec. 19 175A(b). 20 21 The document includes

a brief discussion
of the PM 10 regulatory history of the Payson area,

a 22 description
of the community and maintenance area, an updated emissions inventory, demonstration 23 of continued LMP eligibility and discussion
of regulatory commitments made to preserve 24 maintenance

of the NAAQS. 25 26 This concludes the explanation period of this proceeding
on the proposed revision
to the state 27 implementation plan. 28 29 MS DEBORRAH MARTINKOVIC:
Are there any questions before we move to the oral comment 30 period?
