1.0 INTRODUCTION

This document fulfills the obligation, under the Code of Federal Regulations (CFR), Title 40, Section 

58.10(a), requiring Arizona Department of Environmental Quality (ADEQ) to complete and submit to 

the U.S. Environmental Protection Agency (EPA) an annual network monitoring plan for the year 2009. 

40 CFR, Part 51 requires states to create, submit, and adopt State Implementation Plans (SIPs) to 

address the various issues and responsibilities involved with creating and implementing air quality 

programs. Subpart J of Part 51 specifies that Part 58 Subpart B contains the requirements for 

establishing air quality surveillance systems to monitor ambient air quality. 

Air quality surveillance systems consist of networks of monitors at carefully-chosen physical locations 

referred to as sites or stations. Some of the networks, sites, and monitors are: 

 State and Local Air Monitoring Stations (SLAMS) 

 National Core multipollutant monitoring stations (NCore) 

 Photochemical Assessment Monitoring Stations (PAMS) 

 Chemical Speciation Network (CSN) 

 National Air Toxics Trends Sites (NATTS) 

 Special Purpose Monitors (SPM) 

 Urban Haze monitoring sites 

 Interagency Monitoring of PROtected Visual Environments (IMPROVE) 

 ADEQ visibility stations located in or near mandatory Class I areas (national parks and wilderness 

areas). Class I monitoring sites are subject to specific siting and operational guidance developed by 

the IMPROVE Steering Committee. 

 AIRNow information sites 

 Source-oriented monitoring sites operated independently by permittees (Industry) 

 Meteorological sites 

This Annual Monitoring Network Plan identifies the purpose(s) of each monitor and provides evidence 

that both the siting and the operation of each monitor meet the requirements in 40 CFR Part 58 

appendices A, C, D, and E as follows: 

 Appendix A – Quality Assurance Requirements for SLAMS, SPMs, and PSD (Prevention of 

Significant Deterioration) Air Monitoring 

 Appendix C – Ambient Air Quality Monitoring Methodology 

 Appendix D – Network Design Criteria for Ambient Air Quality Monitoring 

 Appendix E – Probe and Monitoring Path Siting Criteria for Ambient Air Quality Monitoring 

Results of the annual network review and planning are used to determine how well the network is 

achieving its required air monitoring objectives, how well it meets data users’ needs, and how it should 

be modified (through termination of existing stations, relocation of stations, establishment of new 

stations, monitoring of additional parameters, and/or changes to the sampling schedule) in order to 

continue to meet its objectives and data needs. The network review and planning are performed for the 

purpose of improving the network and ensuring that it provides adequate, representative, and useful air 

quality data.

2.0 PROGRAM AND NETWORK DESCRIPTIONS 

Compliance Networks 

The compliance networks operated by ADEQ are used to demonstrate compliance with several EPA 

programs. The largest compliance network in Arizona consists of monitoring sites operated for the 

purpose of demonstrating compliance with the National Ambient Air Quality Standards (NAAQS) 

for the “criteria” pollutants: carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), 

ozone(O3), particulate matter (PM10 and PM2.5 ), and lead (Pb). In 2009, revised Pb monitoring 

requirements were added to the NAAQS: (1.) sources (by January 1, 2010) having annual ambient air 

emissions that are expected to exceed one ton and (2.) urban areas with population greater than 500,000 

without regard to expected level of emissions. The criteria pollutants are measured using instruments 

that have been certified by the EPA as Federal Reference Methods (FRM) or Federal Equivalent 

Methods (FEM). CFR Part 58 specifies the minimum requirements for determining NAAQS compliance 

including the following network and site criteria: 

 Number and types of monitors required per MSA by pollutant 

 Objectives and spatial scales 

 Sampling frequency 

 Collocation and special NCore-related requirements 

 Meteorology 

 Probe location and other restrictions within a site 

 Periodic performance evaluations 

 Quality Assurance and data reporting 

Data from NCore monitoring sites can be used to demonstrate NAAQS compliance. 

PAMS monitoring sites collect specified O3 precursor concentrations as mandated by the 1990 Clean 

Air Act (CAA) Amendments. In addition, ADEQ participates in Federal grant programs such as NATTS 

and the CSN, which require their own monitoring networks. Data collected by these networks of 

monitors are used to assess and report pollutant concentrations, provide data used in modeling and SIP 

applications, track national trends, and monitor specific point-source emissions. 

NCore Network 

The NCore Multipollutant Monitoring Network is a national network of monitoring sites that integrates 

multiple instruments, including some with trace-level capabilities, to provide representative 

measurements of area pollutants. NCore sites are required under 40CFR, Part 58, Appendix C – 

AMBIENT AIR QUALITY MONITORING METHODOLOGY. Additional NCore information is 

available from the following EPA website: 

http://www.epa.gov/ttn/amtic/ncore/index.html

The NCore Monitoring Plan is included as Appendix F to this Monitoring Network Plan. 
 

State of Arizona Air Monitoring Network Plan for the Year 2009, Page 5 

SIP and Maintenance Area Networks 

ADEQ maintains several air monitoring networks for the purpose of tracking compliance in areas that 

are currently not attaining one or more of the NAAQS or areas where the NAAQS have been met but 

on-going demonstration of compliance is required. Monitoring requirements for these areas are 

described in their associated SIPs. 

Source Oriented Networks

Historically, ADEQ has required several of the major point sources in the state to conduct ambient 

monitoring for criteria pollutants, primarily PM10 and SO2, in and around specific facilities. These 

monitoring networks constitute a subset of the compliance monitoring network described above. ADEQ 

activities with respect to these networks have been limited to regular performance audits and review of 

ambient data submitted by the individual sources. Recently, however, SIP support has required the 

submittal of data by some sources to the Air Quality System (AQS), including review of quality 

assurance documents kept by the sources to support their ambient monitoring programs. Sources located 

near Class I areas are being required to collect PM2.5 data to assess impacts on visibility. 

National Air Toxics Trend Sites (NATTS) 

The NATTS network was designed to monitor and record the concentrations of certain air toxics on a 

national scale. ADEQ accepted federal funding and responsibility for this program in Arizona in 2003. 

Data from EPA’s national monitoring activities are used to estimate national average concentrations for 

these air toxics compounds and to detect trends. Using this information, EPA, states, and local agencies 

can estimate changes in the risks of human exposure. These changes can then be used to support 

changes in environmental policy. As part of the National Air Toxics Assessment (NATA) process, 

ambient air quality data are used to assess the national toxics inventory and long-term hazardous air 

pollutant (HAP) trends. The ADEQ JLG Supersite is the designated NATTS site for the Phoenix 

metropolitan area. 

Photochemical Assessment Monitoring Stations (PAMS) 

Section 182(c)(1) of the 1990 CAA Amendments requires the Administrator to promulgate rules for 

enhanced monitoring of O3 and concurrent monitoring of oxides of nitrogen (NOx), speciated volatile 

organic compounds (VOCs), CO, and meteorology to obtain comprehensive and representative O3 data. 

Immediately following the promulgation of those rules, the affected states began to implement a 

program to improve ambient monitoring activities and the monitoring of emissions of NOx and VOCs. 

Each SIP for the affected areas must contain commitments to implement the appropriate ambient 

monitoring network for such air pollutants. The subsequent revisions to 40 CFR 58 (1993) required 

states to establish PAMS as part of their SIP monitoring networks in O3 nonattainment areas classified 

as serious, severe, or extreme. The principal reasons for requiring the collection of additional ambient 

air pollutant and meteorological data are the widespread nonattainment of the O3 NAAQS and the need 

for a more comprehensive air quality database for O3 and its precursors. ADEQ operates two PAMS 

sites, JLG Supersite and Queen Valley, to represent the Phoenix metropolitan area. 
 

State of Arizona Air Monitoring Network Plan for the Year 2009, Page 6 

Chemical Speciation Network (CSN) 

The CSN was established to meet the regulatory requirements for monitoring speciated PM2.5 to 

determine the chemical composition of these particles. The purpose of the CSN is to determine, over a 

period of several years, trends in concentration levels of selected ions, metals, carbon species, and 

organic compounds in PM2.5.The program began in 1999 with 54 Speciation Trends Network (STN) 

sites across the nation located primarily in or near larger Metropolitan Statistical Areas (MSAs) and has 

increased to 200 sites nationwide. Monitoring at JLG Supersite includes one STN speciation sampler 

and two IMPROVE samplers as part of the CSN network. The collocated IMPROVE samplers provide 

precision information for the IMPROVE network and are used for comparison of the speciation results 

from both programs. In 2009, the Met One SASS carbon channel on the STN speciation sampler will be 

replaced with a URG 3000N carbon sampler as part of the national program. 

Urban Haze Networks

ADEQ operates an urban haze network in the Phoenix metropolitan area and provides funding for 

operation of the Tucson area network by the Pima Department of Environmental Quality. The purpose 

of the networks is to provide policy-makers and the public with information regarding urban haze levels, 

track short-term and long-term urban haze trends, assess source contributions to urban haze, and better 

evaluate the effectiveness of air pollution control strategies on urban haze. Equipment used to evaluate 

urban visibility includes transmissometers, nephelometers, particulate monitors, and digital camera 

systems. 

Class I Area Network and IMPROVE Program

Visibility monitoring networks track impairment in specified national parks and wilderness areas. These 

parks and wilderness areas are called Class I Areas and were designated based on an evaluation required 

by Congress in the 1977 federal CAA Amendments. The evaluation, which was performed by the U.S. 

Forest Service (USFS) and National Park Service (NPS), reviewed the wilderness areas of parks and 

national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, 

and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated 

across the nation, 12 are located in Arizona. Nine sites are located in USFS areas and three sites are 

located in NPS areas. From the Class I Area designations, EPA initiated a nationally-operated 

monitoring network in 1987 called the Interagency Monitoring of PROtected Visual Environments 

(IMPROVE) program. The purpose of the IMPROVE network is to characterize broad regional trends 

and visibility conditions using monitoring data collected in or near Class I Areas across the United 

States. ADEQ currently operates 11 sites with IMPROVE instrumentation. 

AIRNow Reporting 

ADEQ currently utilizes four urban nephelometers to approximate and report PM2.5 data to the AIRNow 

Web site to provide near real-time data for public use. The PM2.5 value is calculated by applying a 

correlation developed between the nephelometer and filter-based measurements. The program is 

voluntary and was originally intended to fill gaps in the AIRNow network until actual continuous 

methods were available. 
 

State of Arizona Air Monitoring Network Plan for the Year 2009, Page 7 

Meteorological Network 

ADEQ collects meteorological data at sites throughout the state to provide weather information for those 

air quality monitoring sites not located near official weather-observing stations. Table 7.3-1 lists the 

sites and parameters measured in this network. 

E-BAM Network of PM10 & PM2.5 Special Purpose Monitors

The current network of E-BAM continuous particulate special purpose monitors (listed in Table 2.0-1) 

is composed of lightweight, portable monitors typically enclosed in self-contained, environmentally 

sealed containers. They can be battery or solar powered for operation at sites without fixed electrical 

power. E-BAMs continuously sample and report particulate concentrations. Data are sampled every 

second and concentrations recorded every minute. E-BAM monitors have been used by many agencies, 

particularly in the western United Sates, to provide continuous, real-time particulate concentration data 

that are very useful for making informed smoke management decisions related to prescribed burns. The 

Green Valley BAMs were replaced by E-BAMs in October, 2008. The E-BAM temporarily placed at 

Cottonwood will be moved to its permanent location in Camp Verde in 2009 when renovations to the 

site are complete. E-BAM instruments are used for special-purpose monitoring only. They are not 

classified as FRMs or FEMs and may not be used to demonstrate NAAQS compliance. Hourly data 

from the E-BAM monitors can be viewed at: http://www.phoenixvis.net/PPMmain.aspx.

3.0 MONITORING NETWORK EVALUATION 

This section describes ADEQ's current monitoring network and identifies monitors that are mandated by 

regulations, SIPs, maintenance plans, and grant requirements (such as NATTS). It also compares the 

status of the network to the EPA monitoring rules. Network changes - site and instrument, current and 

planned - are described in the following section and summarized in Section 3.2. 

3.1 Network Changes 

Site Closures 

Prescott College AQD – The site does not meet site requirements because of the close proximity to tall 

trees and to a nearby road with a high traffic count. These conditions make the Prescott College site 

unsuitable for continued, long-term placement. In addition, environmental control issues (the instrument 

is in a room at the College that may not be temperature-controlled in summer months) have impacted the 

operation of the seasonal O3 monitor. A search for a suitable site will begin in 2009 with the objective of 

moving the monitor to a new location before the start of the 2010 O3 season. 

Tucson U of A Central – The building that housed the site was demolished in 2009 and the site 

converted to a parking lot. The nephelometer, aethalometer, anemometer, and temp/RH monitors were 

removed and relocated to storage in Phoenix for potential future use. The aethalometer is not required 

for any current program and there are three other nephelometers in the Tucson area. 

New Sites 

Lake Havasu City – Kingman MSA – This area (population between 50,000 and 350,000) will require 

an O3 monitor to be sited to capture maximum concentration in the MSA. That location will likely be in 

or near Lake Havasu City and a suitable site will be selected following careful analysis of the potential 

sites that will be identified by our search process and in accordance to O3 network monitoring guidelines 

to be published by EPA in 2009. 

Prescott College AQD replacement – A site will be selected from available sites in or near the city of 

Prescott and in accordance with O3 network monitoring guidelines to be published by EPA in 2009. 

Lead Source Network – EPA has identified two potential sites for implementation of the Pb monitoring 

rule: Hayden and Claypool-Miami, areas close to smelters. ADEQ, or its permitted sources, will be 

identifying locations for these monitors in 2009 in accordance with monitoring guidance to be published 

by EPA in 2009. In accordance with the November 12th, 2008 revision of 40 CFR Part 58, Appendix A, 

paragraph 3.3.4.3, collocated TSP monitors will be required at the site with the “highest Pb 

concentrations in the network” - which would be Hayden if based on historical or National Emissions 

Inventory (NEI) data. 

Ozone non-urban networks – The O3 monitoring regulation requires three non-urban monitors in 

Arizona. New sites are not required because O3 monitors are currently operated by the NPS at Grand 

Canyon National Park, Petrified Forest National Park, and Chiricahua National Monument in Arizona. 
 

State of Arizona Air Monitoring Network Plan for the Year 2009, Page 9 

ADEQ operates O3 monitors at two non-urban sites: Alamo Lake and Tonto National Monument. 

ADEQ believes these sites meet the non-urban network requirement. 

Instrument Changes 

Yuma Courthouse PM10 and PM2.5 Monitors – Access to the roof-mounted PM10 and PM2.5 monitors is 

considered dangerous and not suitable for continued operation. The monitors had previously been 

mounted on a different roof at the Courthouse which was considered adequate. 

The collocated, filter-based PM10 monitors are no longer required for NAAQS compliance following the 

addition of a continuous PM10 TEOM in November 2007 and will be removed from this location. One of 

these, or an identical model filter-based PM10 monitor, will be added to another site in the PM10 network 

to meet minimum collocation requirements. The sites being considered for this collocation are Payson 

Well Site and Bullhead City. This change is planned for the end of June 2009. 

The continuous PM10 TEOM and the filter-based PM2.5 monitors will be moved to a safer, more suitable 

location. The Yuma Supersite is considered the best choice to host the relocated monitors. This change 

is also planned for the end of June 2009. 

Rillito PM10 Monitor – The Rillito 24-hour design value for 2006-2008 places it in the category of 

every other day monitoring. ADEQ is considering installation of a TEOM at this site, but would be 

required to make extensive modifications to the site as well as obtain funding for purchase of a TEOM. 

This will be studied further in 2009. 

JLG Supersite aethalometer – Review of monitoring programs indicate this instrument is not specifically 

required for any monitoring program and operation of this instrument will be discontinued in 2009. Data 

collected from this instrument and its predecessor, a less capable, single-beam model, that began 

operation in 1993, are currently being reviewed and will be reported to AQS. 

JLG Supersite trace-level CO and SO2 – These high-sensitivity instruments are required as part of 

NCore and will replace the current CO and SO2 monitors used for NAAQS compliance following a 

period of concurrent operation. Data from these monitors will be reported to AQS. 

JLG Supersite NOy – See Appendix F (NCore) for waiver request to substitute NOx for NOy. 

JLG Supersite STN carbon channel – Being replaced by URG3000N as part of a national program to 

produce results more consistent with those from IMPROVE samplers. 

Mexico Particulate Monitors – The Andersen dichot monitors were replaced with Thermo 2000D 

Partisol samplers in 2009. These monitors are now operated for ADEQ by a consultant. 

Nogales Post Office PM2.5 – The Met One BAM 1020 will be upgraded in 2009 to an FEM model. 

Rillito PM10 – Replacement of the Partisol monitor with a TEOM is being investigated.

4.0 REQUIRED MONITORING 

4.1 EPA Minimum Network Requirements 

Minimum monitoring activities required by the revised monitoring regulation are described in 40 CFR 

Part 58, Appendix D. In the revised monitoring rule, EPA removed minimum requirements for CO, SO2, 

NO, and Pb. A more recent revision set Pb concentration limits of 0.15 μg/m3 for sources expected to 

emit more than one ton per year and for urban areas with populations exceeding 500,000. The minimum 

monitoring requirements for ozone and particulates are based upon MSA and Combined Statistical 

Areas (CSA) as defined in the most recent decennial census and the historical pollutant concentration in 

that area relative to the NAAQS. Tables 4.1-1 through 4.1-3 list the minimum monitoring requirements 

for PM2.5, PM10, and O3. 

The NAAQS for O3 was changed in March 2008 and includes a secondary standard for eight-hour O3

(both standards are 0.075 ppm). EPA plans to provide updated O3 monitoring guidance sometime in the 

second quarter of 2009. EPA revised the primary and secondary NAAQS for Pb on November 12, 2008. 

Both standards are set at 0.15 μg/m3

4.2 EPA Minimum Sample Frequencies 

PM2.5 

The 40 CFR Part 58.12 (d)(1) states that manual PM2.5 samplers at required SLAMS stations must 

operate on at least a one-in-three day schedule at sites without a collocated continuously operating PM2.5 

monitor. For SLAMS PM2.5 sites with both manual and continuous PM2.5 monitors operating, the 

monitoring agency may request approval from the EPA Regional Administrator for a reduction to onein-six day PM2.5 sampling at SLAMS stations and also for seasonal sampling. The EPA Regional 

Administrator may grant sampling frequency reductions after consideration of factors including, but not 

limited to, the historical PM2.5 data quality assessments, the location of current PM2.5 design value sites, 

and their regulatory data needs. Sites that have design values that are within plus or minus 10 percent of 

the NAAQS (±10% of 35μg/m3

 is 31.5 to 38.5) and sites where the 24-hour values exceed the NAAQS 

for a period of three consecutive years are required to maintain at least a one-in-three day sampling 

frequency. Sites that have a design value within plus or minus five percent of the daily PM2.5 NAAQS 

(±5% of 35μg/m3

 is 33.25 to 36.75) must have an FRM or FEM operating on a daily schedule. 

ADEQ operates a PM2.5 FRM sampler on the one-in-three day sampling frequency at one required 

SLAMS site, JLG Supersite. ADEQ also operates a non-FRM continuous PM2.5 sampler (FDMS 

TEOM) at the site. Data from both monitors are reported to AQS. The data from the continuous monitor 

are reported to AQS using parameter code 88500 and began March 17, 2005. 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 13 

The Nogales Post Office PM2.5 FRM sampler has a design value above the NAAQS and is operated on a 

one-in-six day sampling frequency. ADEQ also operates a non-FRM continuous PM2.5 sampler (BAM) 

at the site. Data from both monitors are reported to AQS. The data from the continuous monitor are 

reported to AQS using parameter code 88501 and began March 2, 2005. ADEQ plans to upgrade the 

BAM sampler to FEM status. Nogales is the only nonattainment area for PM2.5 in Arizona.

The monitoring rule in 40 CFR Part 58.12 (e) states that for PM10 sites, “the minimum monitoring 

schedule for the site in the area of expected maximum concentration shall be based on the relative level 

of that monitoring site concentration with respect to the 24-hour standard...” In rural areas of Arizona 

where there is only one PM10 monitor to represent the area, such as Ajo, Hayden, and Yuma, sites can 

be considered de facto maximum-concentration sites whose operating frequencies must be determined 

using the Ratio-to-Standard diagram in 40 CFR Part 58.12 (e). 

Table 4.2-2 lists the PM10 design values for single monitor areas. Ajo, Hayden, and Rillito, require 

every-other-day monitoring and Yuma requires every-day monitoring. Since every-other-day collection 

(filters) would be economically and operationally impractical for ADEQ, continuous monitors will be 

used by ADEQ. Continuous monitors are operating at the Nogales Post Office (BAM monitor) and 

Yuma Courthouse sites, alongside the filter monitors. At Yuma Courthouse, the BAM monitor was 

replaced with a TEOM monitor in November 2007. All monitors at the Yuma Courthouse will be moved 

or discontinued (see Instrument Changes). TEOM monitors were installed at Ajo and Hayden in the first 

quarter of 2009. A TEOM is being considered for installation at the Rillito site.

4.3 ADEQ Minimum Network Status 

The sections below address the minimum requirements for MSAs under the jurisdiction of ADEQ: 

Flagstaff, Yuma, Prescott, and Lake Havasu City - Kingman. Monitoring in the Maricopa-Pinal MSA 

and Tucson MSA will be addressed by Maricopa, Pinal, and Pima counties in their respective 

monitoring plans. 

PM2.5 

According to Tables 4.1-1 and 4.1-4, the minimum PM2.5 monitoring network for Arizona, excluding 

Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, and Flagstaff MSAs. 

Beginning in January 2008, filter based FRM monitors were added to ADEQ monitoring sites in 

Prescott and Yuma; Flagstaff has had an FRM monitor since the program began in 1999. Table 4.3-1 

lists the most recent three-year average 98th percentile design value concentrations for the existing 

ADEQ network of PM2.5 monitors. Note: the Payson monitor was closed at the end of 2007 and moved 

to the Prescott Valley site since design values were well below the NAAQS and monitoring was no 

longer required.

ADEQ operates non reference method PM2.5 continuous monitors at Nogales Post Office (BAM) and 

JLG Supersite (FDMS TEOM). 

PM10

According to Tables 4.1-2 and 4.1-4, the minimum PM10 monitoring network for Arizona, excluding 

Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, Flagstaff, and Lake 

Havasu City-Kingman MSAs. They all fall under the 100K-250K population category for PM10

monitoring. ADEQ currently operates one or more FRM filter-based PM10 samplers in each MSA. 

Prescott MSA (Yavapai County) – ADEQ has operated a reference method PM10 sampler at Prescott 

Valley since March 2003. The maximum 24-hour value recorded over the last three years (2006-2008) 

of operation is 63 μg/m3, approximately 42 percent of the NAAQS. Therefore, the site is considered a 

low category as described in Table 4.1-2 and the single monitoring site at Prescott Valley is adequate to 

meet the rule requirement. 

Yuma MSA (Yuma County) – ADEQ currently operates a reference method PM10 sampler at the Yuma 

Courthouse, operating on a one-in-six day schedule. A continuous PM10 monitor is also operated at this 

site to meet the every-day frequency required. The site is also required under the current SIP 

Maintenance Plan described in additional detail in section 4.3 of this document. Maximum 24-hour 

concentrations recorded in 2006, 2007, and 2008 were 151, 147, and 92 μg/m3. The area is considered to 

be in the medium category and this monitoring site in Yuma is adequate to meet the rule requirement. 

This site (all instruments) will be relocated in 2009 (cf. tables 3.2-1 and 3.2-2). 

Flagstaff MSA (Coconino County) – ADEQ has operated PM10 samplers at two sites in the Flagstaff 

MSA (Flagstaff Middle School and Sedona Post Office since 1992). In 2000-2008, the maximum 24-

hour concentration recorded at Flagstaff Middle School was 56 μg/m3

 (37 percent of the NAAQS); the 

maximum concentration at Sedona Post Office was 36 μg/m3 (24 percent of the NAAQS). Both sites are 

less than 80 percent of the PM10 NAAQS. Therefore, the sites are considered low category and a single 

monitoring site in the MSA is adequate to meet the rule requirement. Since the Sedona Post Office 

monitor has a long record of low values, it was closed in December 2007 and replaced with a nonreference method E-BAM continuous sampler. ADEQ will continue operation of the Flagstaff Middle 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 16 

School PM10 monitor in 2009. A non-reference method E-BAM continuous sampler was installed at the 

Flagstaff Middle School site to provide continuous measurements for public information. 

Lake Havasu City-Kingman MSA (Mohave County) – ADEQ has operated a PM10 monitor at Bullhead 

City since September, 2003. In the 2006-2008 period, the maximum value was 72 μg/m3 and the design 

value to max ratio was 0.48 verifying the correctness of the 1-in-6 frequency. The Bullhead City 

monitor is required because it is in a maintenance area. 

Ozone 

According to Tables 4.1-3 and 4.1-4, the minimum O3 monitoring network for Arizona, excluding 

Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, Flagstaff, and Lake 

Havasu City-Kingman MSAs. All are in the 50K-350K population category. 

Yuma MSA (Yuma County) – ADEQ closed the Yuma Game and Fish monitor at the end of the 2008 

monitoring season due to logistical problems beyond ADEQ's control. ADEQ reopened the Yuma 

Supersite SLAMS (used during the Western Arizona Sonora Border Air Quality Study in 2006-2007) 

and operated an O3 monitor there during the 2008 season beginning in May for data comparison and is 

now the only site in this MSA. 

 

Prescott MSA (Yavapai County) – ADEQ operated an O3 monitor in Prescott from 1981-1984 and 

reported the data to AQS. The design value during this period was 0.062. ADEQ also operated a monitor 

at Hillside from 1996 through the 2005 season. The design value for 2003-2005 was 0.072 ppm, which 

exceeds 85 percent of the eight-hour NAAQS. However, the Hillside site represented upwind transport 

of O3 into the central Arizona and did not, by design, represent the Yavapai County or Prescott MSA 

population. Because an adequate data record did not exist to represent the MSA, ADEQ established an 

SPM O3 monitoring site at Prescott College with measurements beginning April 1, 2008. This site will 

be relocated when a suitable site is found. 

Flagstaff MSA (Coconino County) – ADEQ operated O3 monitors at three sites in the Flagstaff MSA 

from 1977 through 1985 and reported the data to AQS. The most recent design value from 1983-1985 

data was 0.071 ppm. The NPS has been operating an O3 site at the South Rim of the Grand Canyon 

since approximately 1990. The latest data available from that site indicates a three year average of the 

fourth highest eight-hour concentration of 0.077 ppm in 2005-2007 at this monitor, which is above 85 

percent of the NAAQS. Because it has been over 20 years since ADEQ collected O3 data in the city of 

Flagstaff, ADEQ added an SPM O3 instrument to the Flagstaff Middle School site for comparison with 

NPS data. Measurements began April 1, 2008. 

Lake Havasu City-Kingman MSA (Mohave County) – Following future site selection and installation, 

ADEQ will monitor O3 at this site. 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 17 

Ozone Season 

In accordance with 40 CFR Part 58, Appendix D, Paragraph 4.1(i), ADEQ was granted a modification to 

the January through December O3 season defined in the regulation. The 1998 EPA guidance document 

entitled, “Guideline for Selecting and Modifying the Ozone Monitoring Season Based on an Eight-Hour 

Ozone Standard” supports a shorter O3 season for Arizona based upon data collected from 1990 through 

1995. 

Figure 4.3-1, a summary of data from the sites operated by ADEQ, illustrates that O3 concentrations 

have not typically exceeded 85 percent of the NAAQS during the period from November through 

February and only occasionally in the month of March. 

ADEQ will operate the seasonal monitors from April 1st through October 31st. These site are: Alamo 

Lake, Queen Valley, Yuma Supersite, Tonto National Monument, Flagstaff Middle School, and Prescott 

College AQD. The JLG Supersite will continue to operate on a January to December schedule.

PAMS 

The Arizona PAMS network consists of two ambient air monitoring sites in the Phoenix MSA and a 

wind profiler site for the collection of upper air meteorological data. VOC and carbonyl samplers collect 

ambient air in hydrocarbon (HC) canisters and in cartridges containing silica substrate impregnated with 

acidified 2, 4-Dinitrophenylhydrazine (DNPH), respectively, which are routinely analyzed for chemical 

constituents. The Phoenix area PAMS sites and monitors are described below. 

JLG Supersite – Type 2 PAMS Site: 17th Ave. & Campbell, Phoenix. The JLG Supersite was 

designated a PAMS site in 1999. To meet the revised EPA requirement for daily monitoring, ADEQ 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 18 

contracted with an outside vendor for the operation of an automated gas chromatograph mass 

spectrometer (Auto GC/MS) monitoring system for collection and analysis of PAMS VOCs data at JLG 

Supersite for the 2007 monitoring season. The hourly data were reviewed and submitted to AQS. A 

comparison with the canister samples collected for Toxics VOCs indicated the Auto GC/MS 

measurements were within 15 percent of the canister method results. Analysis of the 2007 results has 

been completed and the successful operation of the Auto GC/MS and the reliability of the results for 

analysis plus the additional information that continuous measurements can provide could support a 

decision to purchase an Auto GC/MS to be operated at JLG Supersite during PAMS season in lieu of 

canister sampling. However, consultation with current users of Auto GC equipment in several different 

agencies confirmed that purchase and installation would cost approximately $100,000 and successful 

operation would require half an FTE on a continuing basis. Since the required manual method of eight 

three-hour canisters running daily is impractical due to increased expenses for staff, shipping, and 

analysis, ADEQ plans to return to the 2006 monitoring schedule of a 24-hour canister sample every 

sixth day at the JLG Supersite during PAMS season for VOCs. This will be reviewed as part of the fiveyear Network Assessment due July 1, 2010. ADEQ also operates carbonyl, O3, NOx, and surface 

meteorological monitoring equipment at JLG Supersite (see Table 4.3-2).

4.5 Source Compliance Network 

Historically, ADEQ has required several of the major point sources in the state to conduct ambient 

monitoring for selected criteria pollutants in and around specific facilities. ADEQ activities with respect 

to these networks have been limited to regular performance audits and review of ambient data. Recently, 

ADEQ has begun to submit a portion of these data to the EPA AQS database to support SIP compliance. 

Sources are required to review these data and submit quality assurance documents to ADEQ with the 

data. 

Table 4.5-1 describes the current source operated network. This monitoring plan does not intend to 

implement changes to these networks. The mechanism to alter these networks is through the permitting 

process in consultation with ADEQ's Permits and Planning Sections.

4.6 Compliance with 40 CFR Part 58.10 (c) 

A process for relocating violating PM2.5 monitors is described at 40 CFR Part 58.10 (c). The rule 

requires that the annual monitoring network plan must document how state and local agencies provide 

for the review of changes to a PM2.5 monitoring network that impact the location of a violating PM2.5

monitor or the creation/change to a community monitoring zone, including a description of the proposed 

use of spatial averaging for purposes of making comparisons to the annual PM2.5 NAAQS as set forth in 

Appendix N to Part 50 of this chapter. The affected state or local agency must document the process for 

obtaining public comment and include any comments received through the public notification process 

within their submitted plan. 

ADEQ does not intend to establish community monitoring zones as described in the rule or utilize 

spatial averaging for comparison to the PM2.5 NAAQS. A public comment procedure is required prior to 

relocation of a violating monitor and ADEQ will utilize the following procedure: 

1. Evaluation of the potential replacement site will include review and comparison of available 

pollutant data, meteorology, climatology, terrain, and siting characteristics. This information will 

be documented in a brief report. 

2. Make notice of such a change in the annual monitoring plan. 

3. If the change must be accomplished prior to annual monitoring plan submittal, ADEQ will make 

appropriate notice via the agency Web page and invite participation from the public prior to 

relocation of the affected site. 

4. Relocation of affected monitor. 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 22 

5.0 MONITORING PLAN QUALITY ASSURANCE 

5.1 40 CFR Part 58 Appendix A – Quality Assurance Requirements 

Appendix A specifies the quality assurance requirements for SLAMS, SPMs, and PSD Air Monitoring. 

It describes requirements for the quality system, measurement quality checks for the monitors, 

calculations for data quality assessments, and reporting requirements. 

5.2 Quality System Requirements 

ADEQ is the Primary Quality Assurance Organization (PQAO) for the monitors it operates. The Quality 

Assurance (QA) Team is in the Data Management & Quality Assurance Unit in the Air Assessment 

Section along with the Air Monitoring Unit. The QA Team has several responsibilities to ensure a 

quality monitoring program is operated by ADEQ: 

 coordinating the preparation of the Quality Assurance Project Plan (QAPP) documents and 

Standard Operating Procedures (SOPs) for monitoring programs and projects, 

 conducting performance audits on ADEQ, source, and Pinal County monitors, and 

 conducting Technical Systems Audits (TSAs) on ADEQ monitor operators and on the Filter 

Laboratory. 

The QA Team Lead is a member of ADEQ's agency level QA team. 

Quality Documents 

ADEQ has a Quality Management Plan in place for the agency that was completed in August 2005. Air 

Assessment submitted a Quality Assurance Project Plan to EPA Region 9 in November 2001. ADEQ 

uses the QAPPs prepared for EPA for the IMPROVE and STN monitoring programs. 

ADEQ's revised National Air Toxics Trends Stations, Air Toxics Monitoring Program, & Photochemical 

Assessment Monitoring Stations QAPP (submitted September 2007) was approved by EPA Region 9 in 

February 2008. 

A QAPP was prepared for the PM2.5 program when it began in 1999. Updates to the QAPP were 

submitted to Region 9 in August 2006. QA Plans for gases and particulate matter are next for revision 

and may be combined into a single project plan document. All instrument SOPs have been completed 

and submitted to EPA Region 9. 

Audit Team Responsibilities 

The QA Team conducts performance audits of Air Assessment monitors, Pinal County monitors, and 

some source monitors. All gas and flow rate standards used by the QA teams are traceable to NIST. 

Standards are checked annually. The gas calibrator and O3 standard used by the Team are checked twice 

per year. 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 23 

The QA Team conducts technical system audits of the ADEQ Filter Laboratory. The QATeam has 

updated the SOP used for TSAs of ADEQ's Filter Laboratory. 

The Team has prepared procedures for conducting TSAs of the Southern Regional Office (SRO) and 

Northern Regional Office (NRO) staff who act as operators for the Monitoring Unit. 

The Team conducts performance audits of 11 IMPROVE samplers. ADEQ will conduct TSAs on only 

the 6 protocol samplers. Two samplers per year will receive the TSA. 

EPA Audit Responsibilities 

ADEQ has agreed to participate in the EPA National Performance Audit Program (NPAP) and the PM 

Performance Evaluation Program (PEP). ADEQ has consented to have EPA use a portion of ADEQ's 

grant funds to conduct these audit programs through IFC Consultants. NPAP and PEP audits are 

expected to occur in 2009/2010. 

EPA Region 9 conducted a TSA of the Air Assessment Monitoring Program in December 2004. The 

next TSA is scheduled for September 2009. A TSA of the NATTS station was initially planned for 

January, 2009, but it has been postponed indefinitely. 

ADEQ’s filter lab participated in EPA’s (OAQPS) Inter-Lab (round-robin) testing with excellent results 

that may be obtained from OAQPS. 

5.3 Measurement Quality Checks – Precision Measurements 

5.3.1 Particulate Monitors – Manual Methods – PM10

ADEQ operates two types of PM10 samplers with different methods: dichots and partisols. The dichots 

are located at the two Mexico locations. Because the dichot samplers in Mexico are not collocated, 

precision data are not collected for this method. PM10 concentrations from the dichot samplers are 

reported to AQS designated as monitor type 'Other'. In 2009, the Anderson dichots were replaced by 

Thermo 2000-D Partisol samplers. Data are reported to AQS in standard (81102) and local conditions 

(85101). 

The partisol samplers are located at 10 sites. Concentration data from all 10 sites are reported to AQS in 

standard and local conditions. All sites are designated as SLAMS. Section 3.3.1 of CFR Part 58 

Appendix A indicates that 15 percent of the sites must be collocated. The collocated monitors must be 

within four meters of each other and at least one meter apart for flow rates less than 200 liters/min. 

ADEQ's collocated samplers are listed in Table 5.3-1 and comply with these requirements. All 

concentrations from the collocated samplers are reported to the AQS with parameter occurrence code 

(POC) 2. 

Collocated samples are collected every 6th day for precision measurements. Flow rate verification is 

checked monthly and instrument calibrations are performed twice a year by Monitoring Unit staff.

*Collocated site will be moved in 2009 to either Payson Well Site or Bullhead City. 

ADEQ will continue to report PM10 concentrations to AQS for three monitors at two sites (Miami 

Ridgeline and Golf Course-collocated site) designated as 'Industrial' to support SIP requirements for the 

Miami attainment area. These monitors are operated by the Freeport-McMoRan (formerly Phelps Dodge 

Corporation) as a permit requirement. Freeport-McMoRan supplies flow check and calibration reports to 

ADEQ which conducts performance audits to verify adherence to quality assurance procedures. 

5.3.2 Particulate Monitors – Manual Methods – PM2.5 

The PM2.5 network must include collocated sampling at 15 percent of the monitoring sites operated by 

the reporting agency. If the area has less than four sampling sites at least one must have a precision 

measurement. The total number of sites shown in Table 5.3-2 includes all PM2.5 samplers in the ADEQ 

network (this excludes sites operated by County and Tribal agencies).

 Excludes sites operated by Tribal Programs, Maricopa County, Pima County, and Pinal County. 

All six ADEQ sites (Douglas Red Cross, Flagstaff Middle School, JLG Supersite, Nogales Post Office, 

Prescott College AQD, and Yuma Courthouse) are designated as SLAMS. Concentrations from all 

samplers are reported to AQS. All concentrations from the collocated monitors are reported as POC 2. 

Collocated samples are collected every sixth day to ensure an adequate number of precision 

measurements. 

Flow rate verification is checked monthly and instrument calibrations are performed twice a year by 

Monitoring Unit staff. 

5.3.3 Gas Monitors – SO2, O3, CO, NO2

One-point zero span checks are conducted biweekly and multipoint calibrations are performed quarterly 

by the monitoring staff for all gas monitors. These measurements are reported to the AQS. 

NPAP through-the-probe audits are conducted annually for precision measurements. 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 25 

All shelters for the gas monitors contain temperature probes. The shelter temperature is checked daily 

via the Data Collection System to verify proper operating conditions for the monitors. Shelter 

temperatures are required to be 20o to 30o C. 

5.4 Measurement Quality Checks – Accuracy Measurements 

5.4.1 Particulate Monitors – Manual Methods

The QA Team conducts semi-annual performance evaluation audits (flow rate audits on ADEQ PM10

and PM2.5 monitors). All accuracy measurements are reported to the AQS. PEP audits are conducted 

once a year by EPA and used for measuring bias. 

5.4.2 Gas Monitors – SO2, O3, CO, NO2

The QA Team conducts annual audits of all gas monitors. These are multi-point performance evaluation 

audits. The audit measurements are reported to the AQS. When the NCore program is implemented in 

July 2010 the audits will increase and be conducted on a semi-annual basis. 

5.4.3 Meteorological Equipment 

Meteorological equipment is audited by the QA Team annually. The meteorological equipment at the 

designated NCore site will be checked twice per year. 

5.5 Calculations and Reporting 

ADEQ submits the required AQS precision and accuracy report along with the Data Completeness 

Report to Region 9 in the annual Certification Letter per certification guidelines. As stated above, all 

collocated PM measurements are submitted quarterly to AQS as POC 2, with an indication of which 

monitor is the primary. AQS then calculates the precision statistics. The gaseous biweekly checks are 

submitted quarterly as precision records. Audit information for both PM monitors and gas monitors are 

also submitted quarterly. 

The QA Team has developed a method following EPA guidelines for performing the calculations 

described in Section 4 of CFR Part 58 Appendix A on a regular schedule. 

5.6 Ambient Air Quality Monitoring Methodology 

ADEQ meets the required monitoring methodology for monitors used in compliance applications. A 

complete description of monitoring methods by site and monitor is located in section 6.0 of this 

document.
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 26 

5.6.1 Monitoring Objectives and Spatial Scales 

As stated in Appendix D of 40 CFR Part 58, ambient air monitoring networks must be designed to meet 

the following objectives: 

 Provide air pollution data to the general public in a timely manner. 

 Support compliance with ambient air quality standards. 

 Support air pollution research and strategy development. 

To meet these objectives, the design of ambient air monitoring networks must consider the physical and 

chemical behaviors of the individual pollutants - including properties such as transport and dispersion. 

The locations of a network’s monitoring stations are selected to achieve one or more of the six basic 

objectives specified in 40 CFR Part 58 Appendix D: 

1. Determine the highest concentrations expected in the area covered by the network. 

2. Measure representative concentrations in areas of high population density. 

3. Determine the impact of significant sources or source categories on air quality. 

4. Determine general background concentration levels. 

5. Measure regional pollution transport among populated areas. 

6. In support of secondary standards, to determine the welfare-related impacts in more rural and 

remote areas. 

Appendix D of 40 CFR Part 58 provides guidance concerning spatial scales of air parcels in which the 

pollutant concentration is reasonably similar. Monitoring stations are sited in one of the following scales 

of representativeness: microscale, middle scale, neighborhood scale, urban scale, or regional scale (see 

Table 5.6.1-1). The scale is usually chosen based on the pollutant to be monitored; however, it may be 

determined by the site objective as in the case of monitoring O3 levels downwind of a major 

metropolitan area. 

Table 5.6.1-1 Scale of Representativeness 

Scale of Representativeness Dimension 

Micro several meters up to 100 meters 

Middle 100 meters up to 0.5 kilometers 

Neighborhood 0.5 kilometers up to 4 kilometers 

Urban 4 kilometers up to 50 kilometers 

Regional rural areas or cities of homogeneous geography; can 

extend from tens to hundreds of kilometers 

National and Global thousands of kilometers 

The typical relationship between the monitoring objectives and spatial scale is summarized in Table 

5.6.1-2. Appendix D of 40 CFR Part 58 provides additional detail concerning spatial scales for specific 

pollutants.

5.6.2 General Monitoring Requirements 

 NCore Multipollutant Site – ADEQ JLG Supersite will be designated as an urban NCore site in 

the timeframe specified in the revised 40 CFR Part 58. The scale of this site is neighborhood, 

which complies with the recommendations in Part 58. Continuous monitoring methods will be 

employed where available. The data will be reported (AQS) and made available for air quality 

trends analyses, model evaluation, and NAAQS compliance. 

 SLAMS – Although Part 58 states that SLAMS sites, other than NCore, are intended to address 

specific air quality management interests and are frequently single-pollutant measurement sites, 

many of ADEQ’s SLAMS sites are multipollutant for several reasons including the size of 

ADEQ’s territory and the economic benefits achieved when such sites meet multiple pollutantobjective requirements. 

5.6.3 Pollutant-Specific Design Criteria for SLAMS Sites 

See also section 4.3 ADEQ Minimum Network Status in this document for specific information on the 

monitoring networks in three MSAs under ADEQ jurisdiction: Flagstaff, Prescott, and Yuma. The 

following sections include more general pollutant-specific design criteria. 

 Ozone – More than the specified minimum could be required to support public data reporting, air 

quality mapping, compliance, and O3-related research. This is particularly true of the PhoenixMesa-Scottsdale MSA that includes Maricopa and Pinal Counties but not of the Flagstaff, 

Prescott, or Yuma MSAs. Factors considered were the MSAs geographic sizes, population 

densities, meteorology, terrain, air transport, and the presence of O3 precursors. Section 3.2 

provides background information on the current and historical O3 monitoring sites. EPA is 

preparing revised O3 monitoring guidance requirements for the new NAAQS. Written guidance 

has not been received from EPA to date. The frequency of performance evaluation audits will 

increase to twice per year at the NCore monitoring site when the program is implemented. 

ADEQ will continue to participate in the NPAP program as well. 

 Carbon Monoxide – There are no minimum requirements for the number of CO monitoring 

stations, but continued operation of existing sites is required – the JLG Supersite, in this case. In 

addition, where SLAMS (and, presumably NCore) CO monitoring is ongoing, at least one site 
State of Arizona Air Monitoring Network Plan for the Year 2009, Page 28 

must be maximum concentration. At present, the CO monitoring objective at the JLG Supersite 

is population, but other sites in the Phoenix MSA combine to meet the maximum concentration 

requirement. 

 Nitrogen Dioxide – There are no minimum requirements for NO2 but existing sites must 

continue to monitor unless authorized by the Regional Administrator to be discontinued. As with 

continued CO monitoring, continued NO2 monitoring implies that at least one NO2 monitoring 

site must be a maximum concentration site. The JLG Supersite objective for NO2 monitoring is 

population, but other sites in the Phoenix MSA combine to meet the requirement. 

 Sulfur Dioxide – There are no minimum requirements for SO2 but existing sites must continue to 

monitor unless authorized by the Regional Administrator to be discontinued. ADEQ monitors 

SO2 emissions at the JLG Supersite and at several mining sites. 

 Lead – The new Pb standard is 0.15 μg/m3

. Source-oriented Pb monitoring is planned for two 

sites (Hayden and Miami). Non-source-oriented monitoring is being performed as part of the 

PM10 metals (NATTS) data collection. 

 Particulate Matter (PM10) – Refer to section 4.3 ADEQ Minimum Network Status. 

 Fine Particulate Matter (PM2.5) – Refer to section 4.3 ADEQ Minimum Network Status. 

 Coarse Particulate Matter (PM10-PM2.5) – The ADEQ NCore site will meet requirements.

7.0 ADEQ SUPPLEMENTARY NETWORKS 

7.1 Class I Visibility Network 

Visibility monitoring networks track impairment in specified national parks and wilderness areas. These 

parks and wilderness areas are called Class I Areas and were designated based on an evaluation required 

by Congress in the 1977 federal CAA Amendments. The evaluation which was performed by the U.S. 

Forest Service (USFS) and National Park Service (NPS) reviewed the wilderness areas of parks and 

national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, 

and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated 

across the nation, 12 are located in Arizona. 

From the Class I Area designations, EPA initiated a nationally-operated monitoring network in 1987 

called the Interagency Monitoring of PROtected Visual Environments (IMPROVE) program. The 

purpose of the network is to characterize broad regional trends and visibility conditions using 

monitoring data collected in or near Class I Areas across the United States. Originally the national 

IMPROVE network was made up of approximately 30 sites at Class I areas; during 1999-2000 the 

number of sites increased to approximately 110. In 1996 ADEQ began to add monitoring sites in or near 

Class 1 areas in the state in order to supplement the IMPROVE network. 

The Arizona Class I Visibility Network consists of a combination of visibility monitoring sites 

established by ADEQ and those established by the IMPROVE committee. Monitoring for this purpose is 

conducted at the sites described in Table 7.1-1. Table 7.1-2 describes supplemental monitoring 

conducted by ADEQ to support the IMPROVE program and Regional Haze planning and technical 

analysis.

7.2 Urban Haze Network 

ADEQ monitors the Phoenix and Tucson metropolitan areas with a network of instruments to 

characterize and quantify the extent of urban haze. There are no established federal or state standards for 

acceptable levels of urban haze. ADEQ began studying the nature and causes of urban hazes by 

conducting a study in the winter of 1989-90 in Phoenix and the winter of 1992-93 in Tucson. These 

studies recommended long-term, year-round monitoring of visibility. In 1993, ADEQ began deploying 

visibility monitoring equipment in Phoenix and Tucson. These visibility monitoring data are needed to 

provide policymakers and the public with information, track short- and long-term trends, assess source 

contributions to urban haze, and better evaluate the effectiveness of air pollution control strategies. 

Equipment used to evaluate urban visibility includes transmissometers, nephelometers, aethalometers, 

particulate monitors, and digital camera systems. 

The Phoenix urban haze network includes two transmissometers (located in Phoenix and Mesa) for 

measuring light extinction along a fixed path length of about three to five kilometers, four 

nephelometers for measuring light scattering, six digital camera systems to record visual characteristics 

of the urban area, and particulate filters for quantifying and characterizing particulate matter. The 

Tucson urban haze network includes one transmissometer for measuring light extinction along a fixed 

path length of about three to five kilometers, three nephelometers for measuring light scattering, and a 

digital camera system operated by Pima County to record visual characteristics of the urban area. The 

sites are described in Table 7.2-1. The U of A Central site in Tucson was closed due to the demolition of 

the building housing it and not replaced

7.3 Meteorology Network 

ADEQ collects meteorological data to provide weather information for the monitoring sites not located 

near official weather stations. Much of the equipment is located at visibility monitoring sites. Two 

locations collect data used to meet PAMS meteorological requirements. All meteorological data (with 

the exception of profiler and sodar measurements) receive two levels of quality assurance checks. The 

equipment is audited annually. The sites and instrumentation operated by ADEQ are listed in Table 7.3-

Yuma Mesa

Site Purpose: metrological support. 

The site is located at U of A Agriculture Center. The surrounding area is citrus groves and 

open, grassy fields. Due to the adjacent area the Temp/RH monitor does not meet the EPA 

Meteorological guidance (EPA-454/R-99-005, EPA, 2000) since the monitors would need to 

be 100 meters from the trees and sitting to these specifications is impossible. Recommendation 

is to operate the site and consider potential effects of trees when analyzing data.

JLG Supersite (04-013-9997) – ADEQ’s NCore Site 

JLG Supersite has a long history of multi-pollutant monitoring beginning in 1993 with 

the National Ambient Air Quality Standards (NAAQS). Photochemical Assessment 

Monitoring Stations (PAMS) and Chemical Speciation Network (CSN) were added in 

1999 and National Air Toxics Trends Sites (NATTS) in 2001. JLG Supersite also 

hosts collocated IMPROVE monitors and other instruments including Hexavalent 

Chromium, Speciated VOC (PAH), and meteorology. Trace-level carbon monoxide 

and sulfur dioxide instruments are being tested and readied for installation. All 

required monitoring (with the exception of PM10-2.5 speciation) will be operational 

on or before January 1, 2011. A NOy waiver request and justification are included in 

this appendix. 

JLG Supersite is housed in two climate-controlled shelters in an urban neighborhood 

not overly influenced by local or topographical conditions. Ample exterior space is 

provided by the platform covering the two shelters and the space between them. A 

ten-meter tower is anchored to the platform. Multiplexed digital communications 

between this site and ADEQ’s Phoenix office are being implemented as part of NCore 

modifications. 

The required site and instrument information is contained in the following pages. 

State of Arizona Air Monitoring Network Plan for the Year 2009, Page 2 
JLG Supersite 

Site Purpose: NAAQS compliance network, PAMS, NATTS, CSN, NCORE, AIRNow, AQI 

forecasting, monitor urban haze, and meteorological support. 

The site was established to represent air quality in the central core of the Phoenix metropolitan area. 

The surrounding area is primarily residential neighborhoods, with I-17 roughly 1,609 meters west.

Request for NOy Waiver 

As stated in the NCore Readiness Self-Assessment for State/local/Tribal Agencies 

document, “Although the measurement of NOy is required in support of a number of 

monitoring objectives, available commercial instruments may indicate little difference in 

their measurement of NOy compared with the conventional measurement of NOx, 

particularly in areas with relatively fresh sources of nitrogen emissions. Therefore, in 

areas with negligible expected difference between NOy and NOx measured 

concentrations, the Administrator may allow for waivers that permit high-sensitivity NOx 

monitoring to be substituted for the required NOy monitoring at applicable NCore sites.”. 

This is the case with NOy and NOx at the JLG Supersite NCore site. The Thermo 

instrument used to measure NOx is sensitive to 0.05 parts-per-billion. 

A comparison of the 2008 NOy and NOx concentrations at Supersite during the 2008 

ozone season (April – October) shows a difference of less than 2% for the entire season. 

This indicates that only very small concentrations of the NOz components of NOy are 

present at JLG Supersite. NOz components result from the atmospheric oxidation of NOx 

and include nitric acid (HNO3), nitrate radical (NO3), peroxyacetyl nitrates (PAN), and 

many others. 

As a result of the above comparison showing the small difference between NOx and NOy 

at JLG Supersite, NOy will not be sampled and the NOx measurements can be used in 

lieu of NOy. 

Pb-PM10 Non-Source-Oriented Monitor at NCore Site (JLG Supersite) 

Paragraph 4.5(b) of Part 58 Appendix D specifies that the use of a Pb-PM10 monitor can 

be used instead of a TSP monitor “if no existing monitoring data indicating that the 

maximum arithmetic 3-month mean Pb concentration...was equal to or greater than 0.10 

micrograms per cubic meter during the past three years.” That is certainly the case at JLG 

Supersite. In fact, in the past three years the highest maximum value (which is always 

greater than the highest mean value) was only 0.017 micrograms per cubic meter – less 

than 20% of 0.10. While non-source-oriented lead monitoring is not required at NCore 

sites until January 1, 2011, ADEQ has been monitoring lead there since 2005.
