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 United States Environmental Protection Agency (EPA) an annual network monitoring plan for the 

year 2011. 

This plan informs EPA (Region 9) of the monitoring activities ADEQ will undertake July 1, 2011 

through December 2011. However, some changes may occur after the plan is published and approved 

due to unforeseen events at monitoring sites, funding changes, or changes in EPA monitoring 

requirements. Data from ADEQ's monitors are reported to EPA's Air Quality System(AQS) database 

and to AIRNow. Please refer to ADEQ's Annual Air Quality Report for summaries of these data. 

In 40 CFR 51, EPA 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 Prevention of Significant 

Deterioration (PSD) 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 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 5 
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. 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 6 
2.0 ADEQ PROGRAM AND NETWORK DESCRIPTIONS 

ADEQ operates ambient air quality equipment for a variety of Federal and State monitoring programs. 

Detailed descriptions of the equipment deployed for each monitoring program are presented in 

Appendix C. The equipment is grouped by monitoring program or parameter, to easily compare 

instrument specifics across the networks. Appendix D lists the information about each of ADEQ's 49 

monitoring sites, including those sites which ADEQ shares with other agencies or serves as the local site 

operator. General information about the monitoring programs ADEQ participates in is described in the 

following sections. 

2.1 NAAQS Compliance Network 

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). The criteria pollutants are measured using 

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

Equivalent Methods (FEM). 40 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 metropolitan statistical area (MSA) by pollutant 

 Objectives and spatial scales 

 Sampling frequency 

 Collocation 

 Special NCore-related requirements 

 Meteorology 

 Probe location and other restrictions within a site 

 Periodic performance evaluations 

 Quality Assurance 

 Data reporting 

2.1.1 Changes to the NAAQS 

Pb - In November 2008, EPA revised the Pb NAAQS from 1.5 μg/m3

 to 0.15 μg/m3. New requirements 

for the placement of monitors were added: (1) near Pb sources (by January 1, 2010) having annual 

ambient air Pb emissions that are expected to exceed one ton and (2) in non-source urban areas (by 

January 1, 2011) with populations greater than 500,000. In December 2009, EPA proposed revisions to 

these monitoring requirements. In December 2010, the EPA finalized the Pb monitoring requirements 

which required Pb monitoring near sources with Pb emissions greater than 0.5 tons. Monitors near these 

0.5 to one ton sources are to be operational one year from the date of the final rule. Additionally, the 

final rule adjusted the non-source monitoring requirement to be limited to NCore sites, as opposed to the 

500,000 population requirement mentioned in the original November, 2008 final rule. ADEQ has 

installed Pb monitors at the Globe Highway site as well as the Miami Golf Course site, effective 

October, 2010. ADEQ is currently exploring options for Pb monitoring methods at JLG Supersite and 

will have this monitor installed by December, 2011. The Pb monitoring final rule also clarified that Pb 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 7 
monitoring will not be required in the Prescott area, despite Ernest A. Love Field Airport exceeding the 

0.5 ton Pb emissions threshold. 

O3 - In March 2008, EPA revised the eight-hour O3 standard from 0.08 parts per million (ppm) to 0.075 

ppm. Monitoring network revisions included the requirement for locating monitors in urban areas with 

populations between 50,000 and 350,000 and requiring states to operate three non-urban monitors. In 

January 2010, EPA proposed revisions to the level of the standard, requesting comments on lowering 

the standard to a level within 0.060 to 0.070 ppm. No changes were proposed for the monitoring 

requirements. The final O3 NAAQS will be issued in July 2011. 

SO2 - In June 2010, EPA revised the primary SO2 standard by establishing a new one-hour standard at a 

level of 75 parts per billion (ppb). The new form is the three-year average of the 99th percentile of the 

annual distribution of daily maximum one-hour concentrations. It is also revoking the two existing 

primary standards of 140 ppb evaluated over 24 hours and the 30 ppb evaluated over a year. 

Additionally, the EPA required changes to data reporting requirements to include reporting the 

maximum five minute concentration for each hour in addition to the hourly averaged concentrations. 

ADEQ began collecting and processing hourly maximum five minute SO2 concentrations in July and 

August, 2010. New monitoring requirements for placement of monitors were also issued, and monitors 

must be operational by January, 2013. The new monitoring requirements do not result in any SO2

network changes for ADEQ, as population oriented monitors will be covered by Maricopa and Pima 

County agencies and the source oriented monitors have been established for years. 

NO2 - In January 2010, EPA set a new one-hour standard for NO2 of 100 ppb. EPA is retaining the 

annual standard of 53 ppb. The form of the standard is the three-year average of the 98th percentile of the 

annual distribution of daily maximum one-hour average concentrations. New monitoring requirements 

were established including near roadway monitors in urban areas, additional urban monitors in large 

urban areas, and monitors in areas with populations susceptible to NO2 related health effects. The new 

monitoring requirements are not expected to result in any NO2 network changes for ADEQ, as 

population oriented monitors and near roadway monitors will be operated by Maricopa and Pima 

County agencies. 

2.2 State Implementation Plan (SIP) and Maintenance Area Network 

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

currently not attaining one or more of the NAAQS and in areas where the NAAQS has been met, but ongoing demonstration of compliance is required. Monitoring requirements for these areas are described in 

their associated SIPs. 

2.3 Source Oriented Network

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 the permitted facility. These 

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

with respect to this network have been limited to performance audits and review of ambient data 

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

submittal of data by some sources to the AQS, including review of quality assurance documents kept by 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 8 
the sources to support their ambient monitoring programs. ADEQ continues to work with the permitted 

facilities to obtain all ambient air quality data that are required to be reported to AQS. 

 

2.4 NCore Network 

EPA describes the nationwide NCore network composed of approximately 70 urban and 20 rural sites as 

a multipollutant network that integrates several advanced measurement systems for particles, pollutant 

gases, and meteorology. Some of the missions of the NCore network are: 

 Tracking long-term trends of criteria and non-criteria pollutants; 

 Support for long-term health assessments that contribute to ongoing reviews of the NAAQS; 

 Support to scientific studies ranging across technological, health, and atmospheric process 

disciplines; and 

 Support to ecosystem assessments recognizing that national air quality networks benefit 

ecosystem assessments and, in turn, benefit from data specifically designed to address ecosystem 

analyses. 

As required under 40 CFR Part 58.13, ADEQ’s NCore site (JLG Supersite) was operational by January 

1, 2011. All ambient monitoring data required by 40 CFR Part 58 Appendix D(3)(b) will be reported to 

EPA’s AQS database no later than June 30th, 2011. In addition to the above missions and the NCore 

monitoring requirements set forth in the CFR, ADEQ will use the JLG Supersite to test new 

technologies that may be adopted in various ADEQ monitoring networks. Examples would include 

advanced communications and serial data collection, remote span checks and calibrations, high 

sensitivity instrumentation, and instruments that monitor pollutants that may be added to the current 

CFR requirements. Additional NCore information is available from the EPA website: 

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

2.5 Meteorological Network 

ADEQ collects meteorological data at sites throughout the state to support the analysis of ambient air 

quality data and to provide support for exceptional event reporting. Meteorological measurements are 

also required for the NCore and PAMS networks. ADEQ currently meets the meteorological monitoring 

requirements for the NCore and PAMS networks. It is a goal of ADEQ to add meteorological 

instrumentation to most of ADEQ’s monitoring sites that are not currently equipped. Additions will 

occur as time and funding permits. 

2.6 Photochemical Assessment Monitoring Stations (PAMS) 

Section 182(c)(1) of the 1990 Clean Air Act (CAA) Amendments requires the Administrator to 

promulgate rules for enhanced monitoring of O3 that includes concurrent monitoring of oxides of 

nitrogen (NOx), speciated volatile organic compounds (VOC), carbonyls, 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 non-attainment areas classified as serious, severe, or extreme. The principal reasons for 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 9 
requiring the collection of additional ambient air pollutant and meteorological data are the widespread 

non-attainment 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. 

EPA has recently constructed a workgroup to discuss the evaluation and possible re-invention of the 

PAMS program. The scope of the evaluation is extensive and includes PAMS objectives, network 

design, methods, and quality assurance. ADEQ has been an active participant in the PAMS re-invention 

process and will follow this activity closely to be aware of possible future implications for the ADEQ 

PAMS network. 

2.7 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. 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. ADEQ accepted federal funding and responsibility for this 

program in Arizona in 2003. The ADEQ JLG Supersite is the designated NATTS site for the Phoenix 

metropolitan area. 

2.8 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 MSAs. The network 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, a URG 3000N carbon sampler was added and data from that sampler was then used in place of the 

data from the Met One SASS carbon channel. This substitution was made as part of a national program 

designed to make the characteristics of the CSN carbon method match the IMPROVE carbon method 

more closely. 

2.9 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 Wilderness Areas and were designated based on an 

evaluation required by Congress in the 1977 federal CAA Amendments. The evaluation, which was 

performed by the United States Forest Service (USFS) and National Park Service (NPS), reviewed the 

areas of parks and national forests which were designated as wilderness before 1977, were more than 

6,000 acres, and have visual air quality as an important resource for visitors. Of the 156 Class I Areas 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 10 
designated across the nation, 12 are located in Arizona. Nine sites are located in USFS areas and three in 

NPS areas. EPA initiated the nationally-operated IMPROVE monitoring network in 1987 whose 

purpose is to characterize broad regional trends and visibility conditions using monitoring data collected 

in or near Class I Wilderness Areas across the United States. ADEQ is involved with the operation of 6 

sites with IMPROVE instrumentation. Refer to section 4.12 and Appendix B for additional details 

regarding ADEQ’s Class I Visibility and IMPROVE networks. 

2.10 AIRNow Reporting 

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

AIRNow Web site to provide near real-time data for public use in the Phoenix metropolitan area. 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. Several years ago, ADEQ attempted to submit 

additional continuous data to AIRNow via XML format; however, despite assurances that this format 

would be acceptable, AIRNow was not able to process data in this format. ADEQ has recently renewed 

these efforts to provide data to the AIRNow system and is currently working with their contractor to 

modify the existing AIRNow data transfer module. ADEQ hopes to utilize AIRNow’s new AQCSV file 

format to transfer data to AIRNow. 

2.11 Urban Haze Network

Historically, ADEQ operated an urban haze network in the Phoenix and Tucson metropolitan areas. 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. A wealth of urban visibility related data and information have been collected for more 

than a decade in both the Phoenix and Tucson area. Recently, due to budget cuts, this non-mandatory 

program was reduced to operate in the Phoenix Metropolitan Area only. This network includes the 

digital cameras and the nephelometers and transmissometer that support the AIRNow data reporting. 

Additional details regarding ADEQ’s Urban Haze Network can be found in section 4.13. 

2.12 E-BAM Network of PM10 Special Purpose Monitors

The current network of E-BAM continuous particulate special purpose monitors (listed in Table 2.12-1) 

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 useful for making informed smoke management decisions related to prescribed burns. 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. ADEQ uses these monitors for temporary or short 

term monitoring of populated areas that could be impacted by smoke from controlled burns or for 

investigations of complaint responses. Historically, ADEQ’s E-BAM monitors have been configured to 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 11 
measure particles ≤ 10 microns in diameter (PM10). To get a better understanding of smoke impacts in 

these smaller communities, ADEQ is considering changing the configuration on these monitors to 

measure only particles ≤ 2.5 microns in diameter (PM2.5). 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 changes in ADEQ's current monitoring network that have taken place since the 

2010 Network Plan was issued as well as changes planned for the next 18 months. 

3.1 Site Closures 

Tucson Transmissometer Receiver and Transmitter sites – Both of the sites were part of the Urban 

Visibility Program and were closed in 2010 due to budget constraints. 

Prescott College AQD – The site may be closed following the 2012 ozone season. It does not meet siting 

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 AQD site unsuitable for continued, long-term placement of 

the O3 monitor. In addition, environmental control issues (the O3 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 continue in 2011. It is ADEQ’s goal to run O3 monitors at 

two sites in Prescott during the 2012 O3 season so that data from the two sites can be compared. An EBAM monitor is also located at this site. At this time, it is not known if this E-BAM monitor will be 

removed along with the O3 monitor. 

Bethune Elementary School – The following were considerations in deciding to close this site: 

1. Current and ongoing budgetary limitations require the redirection of non-essential resources. 

ADEQ no longer has the resources to conduct monitoring that is not required by regulation. The 

Bethune Elementary School monitor is an SPM and not required by the CFR. 

2. The Maricopa County Air Quality Department (MCAQD) PM10 network provides sufficient 

coverage for attainment / nonattainment determinations in Maricopa County. 

3. The West 43rd, Durango, South Phoenix, Greenwood, and Central Phoenix sites provide data that 

are representative of the Bethune Elementary School monitor.

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 12 
Snowflake – An E-BAM was added in 2010 for a period of one year for smoke management 

information. This was a temporary study which ended in May, 2011. This E-BAM monitor will be 

redeployed to its original location in Show Low, AZ. 

3.2 New Sites 

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

an O3 monitor to be sited to capture maximum concentration in the MSA. The location would likely be 

in or near Lake Havasu City. A suitable site would be selected following careful analysis of the potential 

sites identified by our search process and in accordance with O3 network monitoring guidelines. While a 

site in the Lake Havasu area has been under consideration for the past several years, delays in the 

promulgation of the O3 NAAQS and the associated monitoring rule have delayed this process. 

Globe Highway – This location was selected for the Hayden area Pb monitor in accordance with 

monitoring guidance published by EPA. EPA Region 9 has concurred with the selection of this site. 

Collocated TSP monitors were installed at this site in October 2010 as part of ADEQ's Pb network. A 

meteorological tower along with instrumentation to measure wind, temperature, and relative humidity 

were also installed in Spring, 2011. 

Miami Golf Course – This location was selected for the Miami area Pb monitor in accordance with 

monitoring guidance published by EPA. A Pb TSP monitor was installed at this site in October 2010. A 

meteorological tower along with instrumentation to measure wind, temperature, and relative humidity 

were also installed in Spring, 2011. 

Replacement for Prescott College AQD – An O3 monitor will be located at a new site in Prescott prior 

to the start of the 2012 O3 season. The current site does not meet siting requirements because of the 

close proximity to tall trees and to a nearby road with a high traffic count. 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 s

will continue in 2011. It is ADEQ’s goal to run O

ite 

3 monitors at two sites in Prescott during the 2012 O3

season so that data from the two sites can be compared. 

3.3 Instrument Changes 

Tucson Urban Visibility Monitors – ADEQ discontinued the operation of all nephelometers and 

transmissometers in the Tucson area due to budget constraints. The affected sites include Children’s 

Park, 22nd & Craycroft, and the Tucson Transmissometer Receiver and Transmitter sites. Supporting 

meteorological instruments were also closed at these sites. These instruments were shut down in May, 

2010. 

JLG Supersite CO and SO2 – High-sensitivity instruments for measurements of CO and SO2 are 

required as part of the NCore program. These ‘trace-level’ monitors were installed at JLG Supersite in 

the fall of 2010. These instruments were operational by January 1, 2011. The older, traditional CO

SO

 and 

2 instruments that were previously used for NAAQS compliance were removed in the spring of 2011. 

Data from these ‘trace-level’ monitors will be reported to AQS in place of the traditional monitors. 

State of Arizona Air Monitoring Network Plan for the Year 2011, Page 13 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 14 

JLG Supersite PMcoarse, PM10, and PM2.5 BAMs – Two FEM BAM instruments and an electronic 

connection between them provide hourly PM10-2.5, PM10, and PM2.5 measurements to meet NCore 

requirements. These instruments were installed in the fall of 2010 and were operational by January 1, 

2011. Data from these instruments will be reported to AQS. 

JLG Supersite PM10, and PM2.5 TEOMs – The PM2.5 FDMS TEOM and the PM10 TEOM instruments 

will be removed following a period of collocation with the paired BAMs system. Simultaneous TEOM 

and BAM monitoring is warranted for a period of time to assess the comparability between the two 

instrument types. After sufficient data are collected, the PM2.5 FDMS TEOM and PM10 TEOM will be 

removed. 

JLG Supersite PM2.5 – The collocated Partisol 2025 PM2.5 instruments will be replaced by a Partisol 

2000 PM2.5. With this change, all PM2.5 filter-based instruments in ADEQ's network will be of the same 

measurement method, eliminating the need for PM2.5 collocation at JLG Supersite since the network 

collocation requirement is already met. This change is scheduled to occur by July 1, 2011. 

JLG Supersite Pb – Recent revisions to the Pb monitoring rule required Pb monitoring at NCore sites 

that are located within a combined statistical area (CBSA) with a population greater than 500,000. The 

Phoenix CBSA meets this population requirement, therefore, Pb monitoring will be required at ADEQ’s 

NCore site (JLG Supersite). Currently, a PM10 low volume sampler produces Pb results as part of the 

NATTS program. ADEQ is currently reviewing the EPA approved methods for both TSP and PM10

collection and analysis methods. ADEQ will continue to review these methods as they become available 

and determine if Pb-PM10 will be an option at JLG Supersite. ADEQ will also determine if an 

‘attainment’ designation is preferred over an ‘unclassifiable’ designation, since the Pb-PM10 data 

collection method cannot be used to show attainment. 

O3 Analyzers – Prior to the 2011 O3 season, all O3 sites were upgraded with newer API Teledyne 

analyzers, which have remote zero and span capabilities. These API Teledyne O3 analyzers replaced the 

TEI 49C analyzers that had been used in prior years. 

Queen Valley Meteorology – During the five-year network assessment, it was discovered that the Queen 

Valley site was not meeting PAMS monitoring requirements as it lacked meteorological measurements 

of wind, temperature, and relative humidity. Meteorological instrumentation was installed at this site in 

the Spring, 2011. 

Hayden Old Jail Meteorology – Pursuant to the recommendation in ADEQ’s five-year network 

assessment to increase coverage in ADEQ’s meteorological network, meteorological measurements of 

wind, temperature, and relative humidity were added to this site in December, 2010.

4.0 ADEQ MONITORING NETWORKS 

Minimum monitoring requirements for the number of sites in SLAMS networks (including PAMS and 

NCore) are described in 40 CFR Part 58 Appendix D and are based on the population of urban areas. As 

EPA reviews the NAAQS for each of the criteria pollutants, additional network monitoring requirements 

for these standards as well as for the other criteria pollutants may be added. The additional requirements 

may be based on population or on some other metric, such as non-urban areas, micropolitan areas, or 

simply at the discretion of the EPA Regional Administration to adequately assess air quality for 

sensitive population groups. Table 4.0-1 lists Arizona's MSA populations.

4.1 PM2.5 Monitoring Network Requirements 

The number of PM2.5 samplers required in urban areas is based on population (see Table 4.1-1) and 

design values for PM2.5 concentrations (see Table 4.1-2).

* 85% of Annual NAAQS (15 μg/m3) = 12.75 μg/m3; 85% of 24-Hour NAAQS (35 

μg/m3

) = 29.75 μg/m3

The frequency of sample collection is based on the type of sampler and the design value calculated from 

data collected at each FRM (filter monitors) or FEM (continuous) sampler (see Table 4.1-2). 40 CFR 

Part 58.12 (d)(1) gives the manual PM2.5 sample collection frequency requirement at required SLAMS 

stations as every third day at sites without a collocated continuously operating PM2.5 monitor. For 

SLAMS PM2.5 sites with manual and continuous PM2.5 monitors, the agency may request approval from 

the EPA Regional Administrator for a reduction to every sixth day and/or seasonal sampling schedule. 

Sites with design values ±10 percent of 35μg/m3

 (31.5 to 38.5μg/m3) and sites where 24-hour values 

exceed the NAAQS for three consecutive years need an every third day frequency. Sites within ±5% of 

35μg/m3 (33.25 to 36.75μg/m3) need to operate on a daily schedule.

ADEQ operates EPA approved FRM samplers at all required PM2.5 monitoring sites. Although the 

required frequency for all PM2.5 FRM monitors is every third day, ADEQ operates only the monitor at 

JLG Supersite at this frequency. Sampling frequencies at the other sites have remained on the original 

every sixth day schedule established when the PM2.5 program was started. Consideration of travel time, 

shipping costs, laboratory processing workload, and little change in annual values through time have 

discouraged changing to the more frequent monitoring schedule. Currently, ADEQ operates continuous 

samplers at two monitoring sites, JLG Supersite and Nogales Post Office. A continuous PM2.5 sampler 

is required at JLG Supersite as part of the NCore requirements. The continuous PM2.5 sampler at 

Nogales Post Office is not an FEM, but is used to supplement the filter-based monitoring at the site

that diurnal patterns in PM

4.1.1 Compliance with 40 CFR Part 58.10 (c) 

A process for relocating violating PM2.5 monitors is described in 40 CFR Part 58.10 (c). It requires the 

annual monitoring network plan to 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. The affected 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 network plan. 

3. If the change must be accomplished prior to annual monitoring network 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 the monitor. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 18 

4.2 PM10 Monitoring Network Requirements 

The number of PM10 samplers required in urban areas is based on population (see Table 4.2-1) and 

design values for PM10 24-hour concentrations (see Table 4.2-2). ADEQ has delegated authority for 

monitoring PM10 to Maricopa, Pinal, and Pima Counties, giving them responsibility for the monitoring 

network for the MSAs within their counties. ADEQ's PM10 monitoring network includes the MSAs in 

all other Arizona counties, as well as the PM10 non-attainment areas in those counties. ADEQ operates a 

PMcoarse monitor (difference method using BAM instruments) in the Phoenix metropolitan area at the 

JLG Supersite NCore site. PM10 concentrations are available from the PM10 BAM instrument to support 

the multipollutant measurements at that site.

100,000 – 250,000 1-2 0-1 0 

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). Due to the variability in PM10

concentrations from year to year throughout Arizona, the operating frequencies of ADEQ PM10

monitors will be evaluated every five years as part of the Five Year Network Assessment. Table 4.2-2 

provides the design values and sampling frequencies for ADEQ’s PM10 monitors. Since exceptional 

events have a large impact on PM10 design values in Arizona, two scenarios are provided. 

In recent years, ADEQ has transitioned several PM10 monitors from filter-based methods to continuous 

methods. As stated in ADEQ’s Five Year Network Assessment, this transition to continuous PM10

samplers continues to be a focus for ADEQ, but there are no plans at this time to transition additional 

filter-based monitors to continuous samplers. ADEQ will be removing the Bethune Elementary School 

PM10 SPM at the end of the second quarter of 2011. This monitor is not required by regulation and 

ADEQ does not have the resources to operate non-essential monitors. A further description of the 

rationale for removing this monitor can be found in Appendix F.

4.3 O3 Monitoring Network Requirements 

The current EPA minimum monitoring requirements for O3 are shown below in Table 4.3-1. EPA has 

proposed revisions to the O3 monitoring requirements, but these revisions have not been finalized. If the 

proposed revisions go final, there will be an affect on ADEQ’s O3 network. Potential effects include: 

 greater coordination with the NPS as their monitors may be used to meet the rural O3 monitoring 

requirement 

 an additional O3 monitor may be needed in the Lake Havasu area to meet the population 

requirement 

 an additional O3 monitor may be needed in a micropolitan statistical area to meet a new 

population requirement. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 20 

 plans. 

ADEQ is basing its current O3 monitoring network off of the current regulations in 40 CFR Part 58 

Appendix D. ADEQ is aware of the potential for changes to the O3 monitoring rule. If EPA does 

finalize their proposed rule, ADEQ will address these changes in subsequent network

ADEQ operates a network of seven O3 monitors throughout Arizona (see Table 4.3-2). Authority to 

operate O3 monitors has been delegated to Maricopa, Pima, and Pinal counties. ADEQ will be relocating 

the Prescott College AQD monitor following the 2012 O3 season due to siting requirements. Prior to the 

2011 O3 season, ADEQ upgraded their O3 monitoring network by replacing the Thermo 43C analyzers 

with newer API Teledyne analyzers. The new API Teledyne O3 analyzers allow for remote zero, span, 

and precision checks which will improve the overall efficiency of ADEQ’s ambient air monitoring 

group.

4.3.1 O3 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. Prior to the 2008 revision to the O3

NAAQS, the 1998 EPA guidance document entitled, “Guideline for Selecting and Modifying the Ozone 

Monitoring Season Based on an Eight-Hour Ozone Standard” supported a shorter O3 season for Arizona 

(April through October) based upon data collected from 1990-1995. During the Spring of 2011, this 

analysis was updated to include the 2008 O3 NAAQS, as well as more recent data. To get the best 

representation of the entire state, data from all O3 sites in Arizona were used in the analysis. For the 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 21 

period 2006-2010, the average number of days above 85 percent of the 2008 NAAQS of 0.075 ppm 

continues to support the operation of seasonal monitors (see Figure 4.3-1). However, the data indicate 

that the O3 season should be extended one month to include the month of March. In 2012 ADEQ plans 

to extend the O3 season by starting to monitor O3 in March instead of April. As shown in Table 4.3-2, 

the current seasonal sites are Alamo Lake, Flagstaff Middle School, Prescott College AQD, Queen 

Valley, Tonto National Monument, and Yuma Supersite. The JLG Supersite will continue to operate on 

a January to December schedule.

4.4 Pb Monitoring Network Requirements 

In November 2008, EPA revised the Pb NAAQS from 1.5 μg/m3 to 0.15 μg/m3. New requirements for 

the placement of monitors were added: (1) near Pb sources (by January 1, 2010) having annual ambient 

air Pb emissions that are expected to exceed one ton and (2) in non-source urban areas (by January 1, 

2011) with populations greater than 500,000. In December 2009, EPA proposed revisions to these 

monitoring requirements. In December, 2010, the EPA finalized the Pb monitoring requirements which 

required Pb monitoring near sources with Pb emissions greater than 0.5 tons. Monitors near these 0.5 to 

1 ton sources are to be operational one year from the date of the final rule. Additionally, the final rule 

adjusted the non-source monitoring requirement to be limited to NCore sites with CBSA populations 

greater than 500,000. ADEQ has installed Pb monitors at the Globe Highway site as well as the Miami 

Golf Course site, effective October, 2010. ADEQ is currently exploring options for Pb monitoring 

methods at JLG Supersite and will have this monitor installed by December, 2011. ADEQ is hoping to 

use the current low volume PM10 metals speciation sampler as the collection method. However, this 

collection method will be dependent upon EPA’s approval of analysis methods for this type of sampling. 

ADEQ hopes to use the same PM10 metals speciation sample that is used for the NATTS program for 

the analysis of Pb. Eastern Research Group (ERG) currently analyzes these samples. The Pb monitoring 

final rule also clarified that Pb monitoring will not be required in the Prescott area, despite Ernest A. 

Love Field Airport exceeding the 0.5 ton Pb emissions threshold.

y NO2 monitors. 

4.5 SO2 Monitoring Network Requirements 

ADEQ operates a network of three SO2 monitors throughout Arizona. Authority to operate SO2 

monitors has also been delegated to Maricopa and Pima counties. ASARCO LLC and Freeport 

MacMoRan Copper and Gold Inc. also operate SO2 monitoring networks in Gila County for compliance 

purposes to support SIP requirements. The SO2 monitoring requirements set forth in 40 CFR Part 58 

Appendix D is based on a Populated Weighted Emissions Index (PWEI) that is calculated for each 

CBSA. CBSAs with PWEIs greater than 5,000 require at least one SO2 monitor. CBSAs with PWEIs 

greater than 100,000 require a minimum of two SO2 monitors. The Phoenix and Tucson metropolitan 

areas are the only areas within the state of Arizona that require ambient monitoring of SO2. The current

SO2 monitors in place that are operated by Maricopa and Pima counties meet or exceed the current 

monitoring requirements set forth in 40 CFR Part 58 Appendix D. ADEQ will continue to operate at 

least one SO2 monitor in the Hayden and Miami areas to support the local facility networks. ADEQ h

been working with these facilities to acquire their SO2 ambient monitoring data for reporting to EPA

AQS database. In the years to come, ADEQ will continue to work with these facilities to review and 

report ambient SO2 data to the AQS database where compliance with the SO2 standard can be easily 

monitored. ADEQ has and will continue to perform annual performance evaluations for these facilities’ 

SO2 monitors. ADEQ also operates a trace-level SO2 monitor at its NCore site (JLG Supersite), as 

required in 40

4.6 NO2 Monitoring Network Requirements

ADEQ operates one NO2 monitor throughout the state of Arizona. This NO2 monitor is located at the 

JLG Supersite. Authority to operate NO2 monitors has also been delegated to Maricopa and Pima 

counties. The NO2 monitoring requirements set forth in 40 CFR Part 58 Appendix D are based on a 

combination of CBSA population and Annual Average Daily Traffic (AADT) counts. The first 

requirement to be considered is the CBSA population. CBSAs with populations greater than 500,000 are 

required to operate one near roadway monitor, while CBSAs with populations greater than 2.5 million 

are required to operate two near roadway monitors. Additionally, CBSAs with populations greater than 

500,000 which also contain roadway segments with 250,000 or greater AADT also require two near 

roadway monitors. As can be seen in table 4.0-1, two CBSAs (Phoenix and Tucson Metro areas) within 

the state of Arizona contain populations greater than 500,000 and therefore require at least one NO2

near roadway monitor. The Phoenix CBSA also exceeds the 2.5 million population requirement, 

therefore two near roadway monitors are needed in the Phoenix CBSA. The required near roadway 

monitors in Tucson and Phoenix will be operated by the local monitoring agencies in their respected 

areas. ADEQ has reviewed population and AADT data and has determined that no other areas in the 

state require near roadwa

In addition to the near roadway monitoring requirements set forth in 40 CFR Part 58 Appendix D, there 

is also a requirement for area-wide NO2 monitoring. CBSAs with populations of one million or more 

require one NO2 monitor to measure NO2 concentrations that represent neighborhood or larger spatial 

scales. The Phoenix and Tucson metropolitan areas are the only areas within the state of Arizona that 

require ambient monitoring of NO2. The current NO2 monitors in place that are operated by Maricopa 

and Pima counties meet or exceed the current monitoring requirements set forth in 40 CFR Part 58 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 23 

Appendix D. ADEQ will continue to monitor NO2 at JLG Supersite as part of the NOx measurements 

which are required for the PAMS program. 

4.7 CO Monitoring Network Requirements 

ADEQ operates one CO monitor throughout Arizona. This CO monitor is a trace level monitor that is 

located at the JLG Supersite to fulfill NCore monitoring requirements. Authority to operate CO 

monitors has also been delegated to Maricopa and Pima counties. There are no CO minimum monitoring 

requirements set forth in 40 CFR Part 58 Appendix D, however, continued operation of CO monitors is 

required until discontinuation is approved by the EPA Regional Administrator. While there are no 

minimum monitoring requirements for CO set for in 40 CFR Part 58 Appendix D, the EPA has recently 

proposed new monitoring requirements for CO. Except for those CO monitors that are required as part 

of the NCore network, the proposed monitoring requirements would not require any area-wide CO 

monitors. However, the proposed monitoring requirements would require near roadway CO monitors in 

CBSAs with populations of one million or greater. These near roadway CO monitors would be 

collocated with the NO2 near roadway monitoring stations. Since the Tucson and Phoenix CBSAs both 

exceed the one million population requirement set forth in the proposed rule, the number of near 

roadway CO monitors would be identical to the number of near roadway NO2 monitors. The required 

near roadway monitors in Tucson and Phoenix will be operated by the local monitoring agencies in their 

respected areas. The one CO monitor that is currently operated by ADEQ meets or exceeds the 

minimum monitoring requirements for both the NCore and CO network design criteria set forth in 40 

CFR Part 58 Appendix D. 

4.8 PAMS Monitoring Network Requirements 

Network design and monitoring requirements for PAMS stations are provided in 40 CFR 58 Appendix 

D for areas classified as serious, severe, or extreme nonattainment for O3. Two sites are required for 

each area, providing all chemical measurements are made. Measurements include speciated VOCs, 

carbonyls, NOx, trace level nitrogen oxides (NOy), CO, O3, surface meteorology, and upper air 

meteorology. In 2008, EPA shortened the PAMS monitoring season to June through August. 

ADEQ's PAMS network consists of two ambient air monitoring sites in the Phoenix-Mesa-Scottsdale 

MSA and a meteorological site for the collection of upper air meteorological data and solar radiation 

data. 

JLG Supersite – Type 2 PAMS Site

The JLG Supersite was designated a PAMS site in 1999. To meet the revised EPA requirement for daily 

monitoring, ADEQ 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. 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 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 24 

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 of a full time employee 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 returned 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 

when the final results of the PAMS re-engineering program are available which may include 

recommendations for changes to monitoring and possibly new types of instruments. ADEQ also 

operates carbonyl, O3, CO, NOx, and surface meteorological monitoring equipment at JLG Supersite 

(see Table 4.8-1). Carbonyl monitoring at JLG Supersite is not currently required for PAMS and could 

be discontinued for the 2012 PAMS season but there are no current plans at this time.

Queen Valley – Type 3 PAMS Site

Queen Valley was designated a PAMS site in 2001. The site is located near the southeastern edge of the 

photochemical modeling grid domain and is considered to be downwind of the source of maximum 

precursor emissions in the Phoenix metropolitan area. Pollutants collected at the site include speciated 

PAMS VOCs, O3, total reactive NOx, and surface meteorology measurements. ADEQ’s Five-Year 

Network Assessment identified the Queen Valley site as not meeting PAMS monitoring requirements 

due to the lack of meteorological measurements. Meteorological instrumentation was added during the 

second quarter of 2011. Carbonyl samples are not required at Type 3 sites. Table 4.8-2 lists the 

instrumentation and monitoring schedule at the Queen Valley site.

4.9 NCore Monitoring Network Requirements 

EPA has identified JLG Supersite as the required NCore site for the Phoenix metropolitan area. JLG 

Supersite has a long history of multipollutant monitoring since its establishment in 1993. Currently, 

several monitoring programs are supported at this site, (SLAMS, PAMS, NATTS, and CSN) as well as 

meteorology. The required NCore parameters are listed in Table 4.9-1. All required NCore monitors 

were operational by January 1, 2011. EPA approved ADEQ's NCore monitoring plan submitted in 2009, 

but did not grant the waiver request to substitute NOx monitoring for NOy.

4.10 SIP Monitoring Network Requirements 

ADEQ is responsible for preparation and submittal of SIPs to EPA for the non-attainment and 

maintenance areas in Arizona. ADEQ is also responsible for conducting ambient air monitoring for 

these areas with the exception of the delegated agreements with Maricopa, Pima, and Pinal counties and 

tribal lands. Permitted sources are also responsible for monitoring air quality, if they are the largest 

source of emissions for that area. Some monitoring sites are specifically named in some SIPs; other 

monitoring sites are not specifically named, but are representative of the air quality in that SIP area. 

Table 4.10-1 lists the ADEQ and source operated monitors used to determine SIP compliance. 

Table 4.10-1 SIP Network Monitoring Requirements 

Note: Sites in italics are specifically required in SIP; others meet the general SIP requirement that representative 

monitoring be conducted (no specific monitoring sites named in SIP).

4.11 Source Compliance Monitoring Network Requirements 

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

monitoring for selected pollutants in and around specific facilities. Some requirements are for 

prevention of significant deterioration (PSD) monitoring prior to operation of the facility. Other 

monitoring requirements are for the duration of the permit. ADEQ activities have been limited to regular 

performance audits of some equipment at these sites and review of ambient data submitted according to 

permit requirements. 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 their data and submit quality 

assurance documents to ADEQ with the data. Table 4.11-1 lists the monitors operated by ADEQ 

permitted sources. ADEQ staff are currently working with ASARCO and Freeport McMoRan staff to 

acquire and report SO2 data from Miami and Hayden to the EPA AQS database.

4.12 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 USFS 

and 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. 

For 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 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 29 

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

number of sites increased to approximately 110. ADEQ, Pima and Pinal counties, and federal land 

managers at Arizona's Class I areas cooperatively operate the visibility monitoring network in Arizona. 

The current network is described in Table 4.12-1. In addition to the Class I IMPROVE monitors listed in 

Table 4.12-1, ADEQ also operates one IMPROVE monitor at the Douglas Red Cross site, and 

collocated monitors at the JLG Supersite. These sites serve as urban IMPROVE monitors. The Douglas 

Red Cross site also serves as a border region IMPROVE site. See Appendix B for a spatial 

representation of the IMPROVE monitoring network and Class I areas within the state of Arizona.

ADEQ's 1996 monitoring plan for the Arizona Class I areas proposed adding optical and meteorological 

monitoring equipment to existing IMPROVE sites to supplement data collected by the IMPROVE 

aerosol monitors with continuous measurements to better characterize the air quality in these areas. 

ADEQ’s 2002 Class I Area Visibility monitoring plan proposed to established protocol sites (completely 

supported by ADEQ following IMPROVE monitoring requirements) to supplement the IMPROVE 

network coverage. Part of the motivation for installing integrating nephelometers at IMPROVE sites 

was a desire to use short term (five minutes) visibility estimates to model the visual experience of a 

visitor to a Class I area. A second motivation for installing nephelometers at IMPROVE sites was to 

provide input to mathematical algorithms that create values that can be compared with the IMPROVE 

measurements to test the performance of the IMPROVE algorithm. Both the original and the revised 

IMPROVE algorithms tend to over-estimate the lowest extinction values typical of the Arizona 

IMPROVE sites. 

Due to budget constraints, ADEQ shut down the Class I nephelometer network in 2010. Over a decade 

of data were collected at several of these nephelometer sites. In early 2011, a draft summary report was 

written which summarizes the nephelometer data that were collected since 1997. The report provides 

comparisons of calculated visibility impairment between the IMPROVE aerosol monitors and collocated 

nephelometers. Summaries and trends in visibility data are also presented within the report, as well as 

meteorological data summaries in the form of wind roses. This report is meant to serve as a final data 

summary for the Class I Nephelometer network. Information from this report may be utilized in the 

future if further modifications are needed to the Arizona Class I visibility network. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 30 

4.13 Urban Haze Monitoring Network 

Historically, ADEQ monitored 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 studies during the winter of 1989-90 in Phoenix and during 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 currently used to evaluate urban visibility includes 

transmissometers, nephelometers, particulate monitors, and digital camera systems. 

The Phoenix urban haze network consists of a transmissometer for measuring light extinction along a 

fixed path length of four and a half kilometers, three nephelometers for measuring light scattering, five 

digital camera systems to record visual characteristics of the urban area, and particulate filters for 

quantifying and characterizing particulate matter. Due to budget constraints, the Tucson urban haze 

network was shut down in September, 2010. Approximately a decade of urban haze data were collected 

in the Tucson area. In early 2011, a draft summary report was written which summarizes the 

nephelometer and transmissometer data that were collected since 1997. The report provides summaries 

and trends in urban visibility data, as well as meteorological data summaries in the form of wind roses. 

This report is meant to serve as a final data summary for the Tucson Urban Haze network. Information 

from this report may be utilized in the future if further modifications are needed to the Urban Haze 

Network. The urban haze sites (and their status) are described in Table 4.13-1.

4.14 Meteorology Monitoring Network 

ADEQ operates meteorological equipment at selected sites throughout its network (Table 4.14-1). Some 

sites were originally established because other meteorology networks (NWS, AZMet, etc.) were not 

located near ADEQ's ambient air quality sites. As recommended in ADEQ’s Five-Year Network 

Assessment, ADEQ has begun to expand the meteorology monitoring network. ADEQ has recently 

added meteorological instrumentation at the following sites: 

 Hayden Old Jail 

 Queen Valley 

 Globe Highway 

 Miami Golf Course 

As resources and funding permits, ADEQ may add additional meteorological equipment at existing 

SLAMS sites. At this time, ADEQ plans to only submit meteorological data that are required by 40 CFR 

Part 58.16 to EPA’s AQS database. If future resources allow additional meteorological data submittals 

to the AQS database, ADEQ may do so on a voluntary basis. A spatial representation of ADEQ’s 

meteorological monitoring network can be found in Appendix B.

5.0 MONITORING PLAN QUALITY ASSURANCE 

EPA specifies the quality assurance requirements for SLAMS, SPMs, and PSD air monitoring programs 

in 40 CFR 58 Appendix A. Data quality objectives, measurement quality objective and indicators, 

quality control (QC) checks for the monitors, calculations for data quality assessments, and data 

reporting requirements are part of the Air Assessment Section's (AAS) quality management system. 

5.1 The Quality System 

All environmental data operations (EDOs) contain some level of uncertainty, or error, associated with 

them. The total measure of uncertainty is the sum of measurement error, which occurs in the data 

collection process, and population uncertainty, which relates to the representativeness of samples. 

ADEQ follows EPA’s quality system approach which uses data quality objectives (DQOs) which are 

developed prior to sampling in a program’s or project’s planning phase. DQOs specify the amount of 

tolerable error that is not to be exceeded in order to make decisions using the air assessment data 

collected for each program’s or project’s specific purpose. To help meet DQOs, measurement quality 

objectives (MQOs), or performance constraints applied to air monitoring instruments, are used to keep 

measurement uncertainty within acceptable limits. Population uncertainty is controlled by proper site 

selection. 

ADEQ serves as the Primary Quality Assurance Organization (PQAO) for the air monitoring stations it 

owns and operates. Being a PQAO streamlines Quality Assurance (QA) efforts by allowing meaningful 

measurement assessments to take place in a shorter period of time, by allowing expensive assessments 

such as collocated precision sampling and EPA-required performance evaluation (PE) audits such as the 

Performance Evaluation Program (PEP) and the National Performance Audit Program (NPAP) to take 

place at less sites and for results to be aggregated at higher levels that are representative of additional 

ADEQ sites. 

As a PQAO, ADEQ uses precision and bias data from air monitoring instruments to assess how well we 

are achieving our established DQOs. Precision is defined as the measure of mutual agreement among 

individual measurements of the same property usually under prescribed similar conditions, and it is the 

random component of error. Precision data are generated from collocated sites and QC checks 

performed by the Air Monitoring Unit (AMU). Bias is the systematic or persistent distortion of a 

measurement process which causes error in one direction. It is determined by estimating the positive and 

negative deviation from the true value as a percentage of the true value. Bias data are generated from 

EPA and in-house PE audits. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 33 

The measurement uncertainty among all ADEQ stations monitoring for the same pollutant is expected to 

be reasonably homogeneous, as a result of common factors existing between those stations. Common 

factors typically include: 

 stations being operated by a common team of field operators and according to a common set of 

field procedures (standard operating procedure (SOP), 

 common calibration facilities and standards, 

 use of a common quality assurance project plan (QAPP), 

 oversight by a common quality assurance organization, and 

 support by a common management, laboratory, or headquarters. 

5.1.1 ADEQ Quality Assurance Staff 

The QA Team is housed in the Data Management & Quality Assurance (DM&QA) Unit and is currently 

composed of two full-time employees specifically dedicated to QA/QC activities. The QA/QC Lead is a 

member of ADEQ's agency level QA team which is chaired by the agency’s QA/QC and Laboratory 

Services Manager. The QA/QC Lead participates in technical assistance document (TAD) development 

with the EPA Office of Air Quality Planning and Standards (OAQPS) when possible. Information 

concerning changes to TADs is communicated to the QA Auditor and AMU staff so that AAS is able to 

comment on pertinent QA changes that affect air monitoring quality, logistics, and resources. The QA 

Auditor manages the PE audit program. In addition, the QA Auditor frequently interacts with air 

monitoring representatives from the tribes and industrial sources for public outreach or compliance 

purposes. 

The QA Team provides oversight and guidance on air monitoring activities to help ensure EPA's QA 

requirements and/or best work practices are met. The QA Team primarily interacts with staff from the 

AMU and Air Filter Laboratory (AFL) both of which are within the AAS. 

The QA Team has numerous responsibilities that include, but are not necessarily limited to: 

 coordinating the preparation of quality documents such as Quality Assurance Program Plans 

(QAPrP) which are required by EPA Region 9 and/or Quality Assurance Project Plans 

(QAPjP) and SOPs as required by EPA OAQPS for operating air monitoring equipment, 

sample handling, and sample processing, 

 conducting Technical Systems Audits (TSAs) of ADEQ air monitoring programs and 

laboratory services, 

 monitoring third-party laboratory performance on TSAs conducted by EPA, 

 conducting PE audits on ADEQ, source, and Pinal County Air Quality Control District 

(PCAQCD) monitors, and 

 reviewing documents such as chain-of-custody forms, data forms, and instrument 

performance forms that relate to DQOs. 

For detailed information on the QA Team’s activities, see the Annual Audit Report. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 34 

5.1.2 ADEQ Quality Documents 

ADEQ has an agency-level Quality Management Plan (QMP) that is managed by the QA/QC Manager 

who reports to the General Services Section in the Administrative Services Division. In 2010, the 

QA/QC Laboratory Services Manager submitted an updated QMP to EPA Region 9. This version was 

approved by the Region 9 Quality Assurance Administrator in November 2010. The QMP describes the 

quality management processes ADEQ uses to maintain a quality management system that supports 

programs involving environmental data or technology. The QMP is an “Umbrella” document which 

details in broad terms the strategies used to carry out QA/QC in environmental data collection activities. 

Per Region 9 guidance, AAS submitted a QAPrP to EPA Region 9 in November 2001, which was never 

approved. This document provided a broad overview of all air monitoring programs AAS operates. This 

document is being replaced by individual QAPrPs which provide more detail for each major air 

monitoring program. QAPjPs are developed for environmental data operations of limited scope and 

duration, such as special studies, which have known beginning and anticipated end dates. These projects 

may involve single or multi-pollutant monitoring, and the QAPjPs may refer to the appropriate QAPrP 

for the pollutant to reduce duplication of effort. In practice, a QAPrP and a QAPjP are commonly 

referred to as a Quality Assurance Program/Project Plan (QAPP). 

In early 2010, the QA Team updated a schedule for managing new and existing QAPPs. The team’s goal 

is to complete two QAPPs per year in addition to accomplishing other QA tasks. In early 2011, it was 

determined that QAPPs for criteria pollutants need to be prioritized. The QAPP schedule was revised to 

reflect the highest priority QAPPs. In 2010, the QA/QC Lead along with staff from AMU began revising 

the National Air Toxics Trends Stations, Air Toxics Monitoring Program, & Photochemical Assessment 

Monitoring Stations QAPP which was approved by EPA Region 9 in February 2008. Completion of this 

QAPP was delayed due to other work priorities. In 2010, the QA Team began coordinating the 

development of a new QAPP for the new Pb monitoring program. This QAPP is nearing completion and 

expected to be submitted to EPA Region 9 for approval in mid-2011. The QA Auditor audits the new Pb 

samplers and ADEQ participates in EPA’s PEP audit program for these samplers. 

Based on communication with EPA, it is not necessary to develop a specific QAPP for NCore. The 

instruments used in the NCore program will be addressed in several program specific QAPPs that 

include, but may not be limited to: the PM2.5, PM10, Gaseous Pollutants, and Meteorological QAPPs. 

The QA Auditor will manage PE audits on these instruments. 

AAS follows the EPA’s QAPP for the PM2.5 STN monitoring program. In late 2009, a new URG 3000 

sampler was added for the collection of elemental and organic carbon. The QA Auditor will conduct PE 

audits on the SuperSASS and URG 3000 four times per year (quarterly) per instrument. An SOP for the 

URG 3000 from EPA is currently in-use. 

SOPs for ambient air quality monitors are included in QAPPs as well as at monitoring sites for 

technicians and operators. AAS SOPs are being revised to follow EPA’s format provided in the 

Guidance for Preparing Standard Operating Procedures (SOPs) EPA QA/G-6. The QA/QC Lead began 

drafting a new in-house guidance procedure for SOP management and this document is still in 

development. The goal is to ensure each SOP contains all pertinent procedures from each Unit within 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 35 

AAS so that all procedures are transparent for staff. This change is expected to improve the usability of 

each SOP while streamlining review efforts. 

5.2 Measurement Quality Checks – Precision and Bias Measurements

AMU QC checks and QA PE audits generate data used to assess the quality of the ambient air quality 

data collected by AAS. The QC checks are used to assess precision, or imprecision actually, introduced 

into air quality data by the monitoring system. The PE audits generate data used to assess the amount of 

bias introduced into air quality data by the monitor. For particulate matter monitors, collocated sampling 

generates precision data as well. The information gleaned from precision and bias data is important for 

data certification and user purposes. This QA information is provided via the AMP 255 report which is 

generated from the EPA’s AQS database. The AMP 255 report is included in Appendix G of this plan to 

demonstrate QA completeness requirements as required in 40 CFR Part 58.10. 

The precision and bias data are reviewed for QA purposes by AMU and DM&QA staff to determine the 

quality of the ambient air data collected. Following reviews, the data are uploaded to the AQS database 

per 40 CFR 58 requirements for criteria pollutants. To date, the national air monitoring programs not 

currently accepting/requiring this precision and bias data include the NATTS and PAMS programs. 

5.2.1 Particulate Monitors – PM10

ADEQ’s current network operates both filter-based and continuous monitors for measuring PM10. 

Currently, Partisol samplers are used for filter-based measurement and both TEOMs and BAMs are used 

for continuous measurements. Flow rate verifications are performed once every four weeks and 

instrument calibrations are performed at minimum once per year or more frequently if needed by AMU 

staff. The QA Auditor performs PE audits on these samplers once every six months. 

Section 3.3.1 of 40 CFR Part 58 Appendix A indicates that 15 percent of the filter-based PM10 sites in a 

network 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 has seven sites and according to the 

rule one collocated site is required. Currently ADEQ runs two collocated filter-based samplers, at 

Payson Well Site and Paul Spur Chemical Lime Plant, which exceeds this requirement. All 

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

(POC) 2. Collocated samples are collected every sixth day for precision measurements. 

5.2.2 Particulate Monitors – PM2.5 

ADEQ’s current network operates both filter-based and continuous monitors for measuring PM2.5. 

Currently, Partisol samplers are used for filter-based measurements and TEOMs, BAMs and 

nephelometers are used for continuous measurements. Flow rate verifications are performed every four 

weeks and calibrations are performed annually or more frequently if needed by AMU. The QA Auditor 

performs PE audits on these monitors once every six months. 

For the PM2.5 network, each filter-based sampling method must include collocated sampling at 15 

percent of the monitoring sites operated by the reporting agency. If the area has less than four 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 36 

monitoring sites at least one must have a precision measurement. ADEQ currently operates six PM2.5

sites which results in one collocated site being required. This requirement is met with the collocation of 

Partisols at the Nogales Post Office site. Previously, collocated PM2.5 sampling also occurred at the JLG 

Supersite; however, with the replacement of the Partisol 2025 instruments with a Partisol 2000 

instrument, collocation will no longer be required at this site. Section 3.2.5.6 of 40 CFR Part 58 

Appendix A requires that 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. Collocated samples are collected every sixth day 

to ensure an adequate number of precision measurements. All concentrations from the collocated 

monitors are reported as POC 2. PEP audits are conducted on PM2.5 filter-based samplers by the EPA. 

The PEP audit results are also used for measuring bias and are reported to AQS by the EPA. The ADEQ 

network has more than five filter-based sites, which requires eight PEP audits distributed evenly over 

four quarters. According to this schedule, all samplers will receive a PEP audit within a six year period. 

ADEQ operates two air samplers, the SuperSASS and the URG 3000, for the PM2.5 STN as part of the 

CSN. Speciation filter samples are collected every third day. There is no collocation requirement for 

these samplers, but data generated from these samplers complement the data generated from the 

collocated IMPROVE samplers at JLG Supersite. Flow rate verifications are performed every four 

weeks and calibrations are performed annually or more frequently if needed. The QA Auditor audits 

each sampler quarterly. Beginning with 2010, all precision and bias measurements are reported to the 

AQS. 

5.2.3 Gas Monitors – SO2, O3, CO, NO2

One-point precision checks, along with zero and span checks are conducted biweekly and multipoint 

calibrations are performed quarterly by AMU for all gas monitors. Multi-point PE audits are performed 

annually by QA. Both measurements are reported to the AQS. NPAP audits are conducted by EPA 

annually for bias measurements. NPAP results are reported to AQS by the EPA. Beginning in July 2010, 

the frequency of these audits increased and are now conducted on a semi-annual basis. 

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

via the data collection system (DCS) to verify proper operating conditions for the monitors. Shelter 

temperatures are required to be between 20o and 30o C. Shelter temperature probes are audited once 

every six months by QA. 

5.2.4 Air Toxics Monitors 

ADEQ’s JLG Supersite in Phoenix is a designated air monitoring station for the NATTS program. AMU 

conducts verifications and calibrations on the samplers used to collect PM10 metals, Polycyclic 

Aromatic hydrocarbons (PAHs), and hexavalent chrome. Calibrations occur once every six months and 

verifications occur on a monthly or quarterly basis. QA conducts PE audits on the same samplers once 

every six months. The VOC sampler is currently calibrated annually by ATEC and certified annually by 

ERG. The carbonyl sampler is currently calibrated annually by ATEC and certified annually by either 

ATEC or ERG. 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 37 

5.2.5 Meteorological Equipment 

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

designated NCore site will be audited once every six months. 

5.3 Calculations and Reporting 

ADEQ submits the required AQS precision and bias report (AMP 255) to Region 9 in the annual 

Certification Letter per certification guidelines and CFR requirements. As stated above, all collocated 

particulate mater (PM) measurements are submitted quarterly to AQS as POC 2. AQS then calculates 

the precision statistics. The PM flow verification data and gaseous biweekly precision check data are 

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

submitted quarterly. 

5.4 ADEQ AQD Audit Responsibilities 

The QA Team conducts PE audits of AAS monitors, PCAQCD monitors, and some source monitors 

whose measurements are used for determining NAAQS compliance. 

5.4.1 Internal Technical System Audits 

In 2010, the QA Team provided support and assistance to AMU in addressing the findings and 

recommendations from the Southern Regional Office (SRO) and Northern Regional Office (NRO) staff 

and operator TSAs. To date, the QA Auditor conducts TSAs on 12 IMPROVE samplers at 11 sites 

operating throughout the state annually. These TSAs are limited to evaluating site conditions and 

instrument performance with occasional operator interaction. Seven of the 12 samplers are “protocol” 

samplers meaning they are owned and operated by ADEQ. The other five samplers are owned and 

operated by EPA. Currently, AAS does not receive funds for the TSAs performed on EPA IMPROVE 

samplers. This schedule was reviewed in 2010 and there have been no changes to the audit services 

provided for IMPROVE program at this time. 

In late 2009, the QA/QC Lead initiated the startup of an Air Toxics Team whose members include 

technicians from AMU, the QA Auditor, and the data management lead. The purpose of this team was to 

prepare for a TSA and to update the NATTS / ATMP / PAMS QAPP and instrument SOPs. The team 

meets on a regular basis to address issues related to air toxics sampling. 

In mid-2010, the QA/QC Lead initiated the startup of a Pb Monitoring Team whose members include 

staff from Special Projects, AMU, the AFL, DM&QA as well as the manager of AAS. The purpose of 

the team was to ensure all pertinent staff were able to work together to develop program-related SOPs 

and the program QAPP. 

5.4.2 ADEQ Rankings in EPA Program Reports 

In early 2009, the QA Team reviewed the report of EPA's PEP audit program. DM&QA staff began 

investigating what changes may have occurred within the PM2.5 network to cause a shift in program 
State of Arizona Air Monitoring Network Plan for the Year 2011, Page 38 

performance over the last nine years. Based on EPA’s Three-Year Quality Assurance Reports for the 

SLAMS PM2.5 Ambient Air Monitoring Program covering years 1999 through 2007, ADEQ's PM2.5

network fell from a high rating to a low rating for bias results. Three areas are under review to identify 

and eliminate source(s) of error occurring in the network in order to reverse this trend. The program 

elements under review include: the sampler and impactor combination, the AFL gravimetric weighing 

process, operator training, and the PEP audit and data assessment process. To date, AFL has participated 

in three round-robins in the Gravimetric Inter-Laboratory Comparison Study conducted by the EPA’s 

National Air and Radiation Environmental Laboratory (NAREL) and scored well on each. AMU is 

currently working on updating their training procedures for those responsible for operating filter-based 

PM10 and PM2.5 instrumentation. Further network evaluation will continue in 2011. 

5.4.3 Technical Assistance Document Development 

In 2010, the process of verifying flow standards used by AMU and QA underwent some review. This 

review was initiated by the QA/QC Lead’s involvement as a reviewer on a new flow standard TAD by 

OAQPS. Currently, most AMU and QA flow standards are certified, or verified, annually. The 

calibrators used by QA for criteria pollutant gases and the O3 standard are checked twice per year. All 

gas and flow rate standards used by AMU and QA Team are traceable to the National Institute of 

Standards and Technology (NIST) flow standard. 

5.5 EPA Audit Responsibilities 

EPA Headquarters and Region 9 each have responsibilities for auditing ADEQ's ambient air monitoring 

program. 

5.5.2 PEP and NPAP Audits 

In 2011, ADEQ will continue to participate in the EPA NPAP and the PM2.5 PEP audits. ADEQ 

consented to have EPA use a portion of ADEQ's grant funds to pay for these audit programs through 

IFC Consultants. NPAP and PEP audits are expected to occur in 2011 as in previous years. Also, PEP 

audits for Pb will begin in 2011 and the cost for this will be covered by EPA this year. 

5.5.2 Technical System Audits 

In September 2009, EPA Region 9 conducted a comprehensive TSA on ADEQ’s air monitoring 

program. Findings and recommendations from the TSA were reviewed by AAS staff and an official 

Corrective Action Plan was submitted to EPA Region 9 in February, 2011. ADEQ will continue to work 

with EPA Region 9 on the findings from the 2009 EPA TSA. EPA Region 9 is required to conduct TSAs 

on the ADEQ monitoring program every three years. 

In April 2010, ADEQ underwent a TSA of the NATTS program. The TSA was conducted by RTI, a 

contractor for EPA. Findings and recommendations from the TSA are being addressed.

Appendix F – Bethune Elementary School Site Removal Rationale 

This document explains the Arizona Department of Environmental Quality’s rationale for removing the 

PM10 special purpose monitor (SPM) from the Bethune Elementary School at the end of the second 

quarter 2011. This rationale includes the following issues: 

1. Current and ongoing budgetary limitations require the redirection of non-essential (nonregulatory) resources. ADEQ no longer has the resources to conduct monitoring that is not 

required by regulation. The Bethune Elementary School monitor is an SPM and not required by 

the CFR. 

2. The Maricopa County Air Quality Department’s PM10 network provides sufficient coverage for 

attainment / nonattainment determinations in Maricopa County. 

3. The West 43rd, Durango, South Phoenix, Greenwood, and Central Phoenix sites provide data that 

are representative of the Bethune Elementary School monitor. 

The first two issues are straightforward and likely well understood by Region 9. The third issue is 

examined in more detail below. It is evident from the figure, table, and graphs below that the Bethune 

Elementary School monitor, and the data from this monitor, is closely bracketed by the five Maricopa 

County monitors. The Bethune Elementary School PM10 monitor is located within 3.5 miles of five 

other Maricopa County PM10 monitors.
