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 2010. This plan informs EPA (Region 9) of the monitoring activities ADEQ will undertake July 1, 2010 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 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 2010, Page 4 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 2010, Page 5 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 54 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 (NO 2 ), sulfur dioxide (SO 2 ), ozone (O 3 ), particulate matter (PM 10 and PM 2.5 ), 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 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 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 requirements to include Pb sources with emissions greater than 0.5 tons but less than 1.0 tons per year with monitors for these sources operational by December 30 2010 or 1 year from the date of the final rule. Non-source monitors are to be located at NCore sites. It is estimated that these proposed requirements will be finalized no earlier than the spring of 2010. O 3 - In March 2008, EPA revised the eight-hour O 3 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 State of Arizona Air Monitoring Network Plan for the Year 2010, Page 6 the standard to a level within 0.060 to 0.070 ppm. No changes were proposed for the monitoring requirements. The final O 3 NAAQS will be issued in August 2010. SO 2 - EPA proposed a new NAAQS primary standard in November 2009. The proposal replaces the 24hour and annual standards with a one-hour standard between 50 and 100 parts per billion (ppb). Additionally, the EPA is proposing changes to data reporting requirements which would require agencies to report the maximum five minute concentration for each hour in addition to the hourly averaged concentrations. The final rule is scheduled to be issued in June 2010. New monitoring requirements for placement of monitors will also be issued, and monitors must be operational by January 2013. NO 2 - In January 2010, EPA set a new one-hour standard for NO 2 of 100 ppb. EPA is retaining the annual standard of 53 ppb. 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 NO 2 related health effects. 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 PM 10 and SO 2 , in and around specific facilities. Sources located near some Class I areas are required to collect particulate data to assess impacts on visibility. 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 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. 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. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 7 NCore sites are required under 40 CFR Part 58 Appendix C to be fully operational by January 1, 2011. 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 pollutant data and to provide support for exceptional event reporting. Meteorological measurements are also required for the NCore and PAMS networks. 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 O 3 that includes concurrent monitoring of oxides of nitrogen (NOx), speciated volatile organic compounds (VOC), carbonyls, CO, and meteorology to obtain comprehensive and representative O 3 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 O 3 non-attainment 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 non-attainment of the O 3 NAAQS and the need for a more comprehensive air quality database for O 3 and its precursors. ADEQ operates two PAMS sites, JLG Supersite and Queen Valley, to represent the Phoenix metropolitan area. 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. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 8 2.8 Chemical Speciation Network (CSN) The CSN was established to meet the regulatory requirements for monitoring speciated PM 2.5 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 PM 2.5 . 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). It 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 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 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 Areas across the United States. ADEQ currently operates 11 sites with IMPROVE instrumentation. 2.10 AIRNow Reporting ADEQ currently utilizes three urban nephelometers to approximate and report PM 2.5 data to the AIRNow Web site to provide near real-time data for public use in the Phoenix metropolitan area. The PM 2.5 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. 2.11 Urban Haze Network ADEQ operates an urban haze network in the Phoenix and Tucson metropolitan areas and provides funding for operation of the Tucson area network by the Pima Department of Environmental Quality (PDEQ). 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. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 9 2.12 E-BAM Network of PM 10 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 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. Hourly data from the E-BAM monitors can be viewed at: http://www.phoenixvis.net/PPMmain.aspx. Table 2.0-1 Location of E-BAM Monitors Site Name Address Flagstaff Middle School 755 N.

Highway 260, Camp Verde, AZ 86322 State of Arizona Air Monitoring Network Plan for the Year 2010, Page 10 3.0 MONITORING NETWORK EVALUATION This section describes changes in ADEQ's current monitoring network that have taken place since the 2009 Network Plan was issued as well as changes planned for the next 18 months. 3.1 Site Closures Green Valley Fire Administration – The PM 10 and PM 2.5 E-BAMS, which had been operated jointly by ADEQ and PDEQ, were closed in February 2010. The monitors where put at this site following specific events in which dust was blown from tailings piles east of Green Valley. Due to improved maintenance procedures of the tailings pile by the mine operator, possibly a result of the monitoring, the monitors were removed and the site was closed. Budget constraints were also a factor in closing the monitors and site. Mesa Transmissometer – The transmissometer pair (transmitter at Banner Mesa Medical and receiver at the Mesa City Building) was considered redundant to the Phoenix Transmissometer pair and was closed in 2009. Show Low – This E-BAM site will be closed in 2010. It is no longer considered necessary for its primary purpose of monitoring for smoke. Yuma Courthouse – This site was closed, due to safety issues, at the end of 2009. The continuous PM 10 TEOM and the filter-based PM 2.5 were moved to Yuma Supersite. One of the collocated, filter-based PM 10 monitors (no longer required for NAAQS compliance following the addition of a continuous PM 10 TEOM) was moved to Payson Well Site to meet minimum network collocation requirements. Yuma Agriculture Center Farm and Yuma Mesa – These sites were part of the meteorological network supporting the Western Arizona Sonora Border Air Quality Study (WASBAQS), which concluded in 2007. The sites are not needed to support any current ADEQ monitoring programs. The meteorological equipment was consolidated and moved to the existing Yuma Supersite to support the O 3 and particulate matter monitors. 3.2 New Sites Lake Havasu City – Kingman MSA – O 3 – This area (population between 50,000 and 350,000) requires an O 3 monitor to be sited to capture maximum concentration in the MSA. The location will likely be in or near Lake Havasu City. A suitable site will be selected following careful analysis of the potential sites identified by our search process and in accordance with O 3 network monitoring guidelines. Hayden – Miami – Pb – EPA has identified two areas close to smelters for implementation of the Pb monitoring rule: Hayden and Claypool-Miami. ADEQ identified the ASARCO Globe Highway location for the Hayden monitors in accordance with monitoring guidance published by EPA. EPA Region 9 has concurred with the selection of this site (see memo in Appendix F). This site will be the collocated site in ADEQ's Pb source network. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 11 A monitoring site in Miami will be identified in 2010. Several issues including Region 9 approval of the Hayden site, funding, and acquisition of the TSP instruments delayed the start of Pb monitoring at these two source-oriented sites. Prescott College AQD – O 3 – The O 3 monitor will be moved to a new site in Prescott after the close of the 2010 O 3 season and prior to the start of the 2011 season. The current site does not meet 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 temperaturecontrolled in summer months) have impacted the operation of the seasonal O 3 monitor. A search for a suitable site will continue in 2010. San Luis Rio Colorado – PM 10 – This Mexico site was added in July, 2009 as part of the border study program. Filter based PM 10 samples are collected at the site. The site is operated by a contractor for ADEQ. Snowflake – PM 10 – An E-BAM will be added in 2010 for smoke management information. 3.3 Instrument Changes Class I Nephelometers – ADEQ is discontinuing operation of nephelometers at nine Class I visibility sites in 2010 due to budget constraints. They are not required by the IMPROVE program, the CFR, or by the Regional Haze Rule SIP, and they have been funded solely by ADEQ. The nephelometers supplemented the IMPROVE aerosol monitors at these sites, providing continuous (five-minute) measurements of light scattering. Arizona has, historically, been a major supporter of the national IMPROVE program by funding approximately one third of its nephelometers while having only one fifth of the IMPROVE sites. Supporting meteorological instruments will also be closed. JLG Supersite trace-level CO and SO 2 – These high-sensitivity instruments are required as part of NCore and will replace the current CO and SO 2 instruments used for NAAQS compliance. Data from these monitors will be reported to AQS. The instruments will be fully operational by January 1, 2011. JLG Supersite PM 10-2.5 , PM 10 , and PM 2.5 BAMs – Two FEM BAM instruments and an electronic connection between them will provide hourly PM 10-2.5 , PM 10 , and PM 2.5 measurements to meet NCore requirements. These instruments must be operational by January 1, 2011. Data from these instruments will be reported to AQS. JLG Supersite PM 10 , and PM 2.5 TEOMs – The PM 2.5 FDMS TEOM and the PM 10 TEOM instruments will be removed by January 1, 2011. The continuous requirement will be met by the paired BAMs for the PM 10 coarse measurement. JLG Supersite PM 2.5 – The collocated Partisol 2025 PM 2.5 instruments will be replaced by a Partisol 2000 PM 2.5. With this change, all PM 2.5 filter instruments in ADEQ's network will be the same instrument make and model, eliminating the need for collocation since the network collocation requirement is already met. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 12 JLG Supersite Pb – Pb monitoring is required in metropolitan areas with populations greater than 500,000, per the current NAAQS. Proposed revisions to the NAAQS designate NCore sites for Pb monitoring. This instrument will be located at the designated NCore site, JLG Supersite. The instrument is required to be operational by one year after the revised NAAQS is published. Currently, a PM 10 loVol sampler produces Pb results as part of the NATTS program. ADEQ Air Assessment staff will determine if this current instrument and analysis method meets EPA requirements. Mexico PM 10 – Thermo 2000D partisol dichot instruments were installed at the Agua Prieta Fire Station and Nogales Sonora Fire Station as intended replacements for the Andersen dichot instruments, providing filter based measurements for PM fine, coarse, and total concentrations. Due to operational difficulties and sampler problems, the 2000D partisol dichot instruments were replaced with two Thermo 2000F partisol filter samplers (measuring PM 10 and PM 2.5 ) at each site in 2010. Payson Well Site PM 10 collocated – A PM 10 2000F partisol instrument was added to the site in July of 2009 to meet network collocation requirements. This was necessary due to the removal of the collocated pair of instruments at the Yuma Courthouse site. Rillito PM 10 – The Rillito 24-hour design value for 2007-2009 ratio with the NAAQS (as stated in 40 CFR 58.12) placed the site in the category of every other day monitoring. ADEQ replaced the filter based partisol instrument with a TEOM at this site in March 2010. Rillito Temperature/Relative Humidity – These meteorological instruments were added to the anemometer at the site when the TEOM was installed. Communications were added to the site for remote automated data collection. Yuma Supersite PM 10 and PM 2.5 – The continuous PM 10 TEOM and the filter-based PM 2.5 partisol sampler began operation at the site on January 1, 2010. Meteorological instruments (anemometer and temperature/relative humidity probe) were also added to the site in March 2010.

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. Table 4.0-1 Arizona MSAs as of the July 2009 Census Estimate MSA Name Area included Population Flagstaff Coconino County 129,849 Lake Havasu City – Kingman Mohave County 194,825 Phoenix – Mesa – Scottsdale Maricopa & Pinal Counties 4,364,094 Prescott Yavapai County 215,503 Tucson Pima County 1,020,200 Yuma Yuma County 196,972 4.1 PM 2.5 Monitoring Network Requirements The number of PM 2.5 samplers required in urban areas is based on population (see Table 4.1-1) and design values for PM 2.5 concentrations (see Table 4.1-2). Table 4.1-1 Minimum Number of PM 2.5 Monitors Required (40 CFR 58 Appendix D) Population (MSA) Most recent 3 yr Most recent 3 yr design value ≥ 85% of design value <85% any PM 2.5 NAAQS * any PM 2.5 NAAQS * >1,000,000 3 2 500,000 – 1,000,000 2 1 50,000 – 500,000 1 0 or 1** * 85% of Annual NAAQS (15 ug/m3) = 12.75 ug/m3; 85% of 24-Hour NAAQS (35 g/m3) = 29.75 ug/m3 ** NCore sites and population-oriented, maximum concentration sites require a minimum of 1. 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 PM 2.5 sample collection frequency requirement at required SLAMS stations as every third day at sites without a collocated continuously operating PM 2.5 monitor. For SLAMS PM 2.5 sites with manual and continuous PM 2.5 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% of 35µg/m3 (31.5 to 38.5µg/m3) and sites where 24-hour values exceed State of Arizona Air Monitoring Network Plan for the Year 2010, Page 16 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 monitoring sites; data from these samplers are used for the 24-hour design value calculations. Currently, ADEQ operates continuous samplers that are not FEMs at only two monitoring sites, JLG Supersite and Nogales Post Office. The Nogales area is non-attainment for the 24-hour PM 2.5 NAAQS. Although the required frequency for all PM 2.5 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 PM 2.5 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. This will be reviewed in the Five-Year Network Assessment. 4.1.1 Compliance with 40 CFR Part 58.10 (c) A process for relocating violating PM 2.5 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 PM 2.5 monitoring network that impact the location of a violating PM 2.5 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 PM 2.5 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 PM 2.5 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. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 17 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. 4.2 PM 10 Monitoring Network Requirements The number of PM 10 samplers required in urban areas is based on population (see Table 4.2-1) and design values for PM 10 24-hour concentrations (see Table 4.2-2). ADEQ has delegated authority for monitoring PM 10 to Maricopa, Pinal, and Pima Counties, giving them responsibility for the monitoring network for the MSAs within their counties. ADEQ's PM 10 monitoring network includes the MSAs in all other Arizona counties, as well as the PM 10 non-attainment areas in those counties. ADEQ does operate PM 10 monitors at two sites in the Phoenix metropolitan area: at Bethune Elementary School (filter-based instrument as a special purpose monitor in the South Phoenix area) and at JLG Supersite (continuous) as a SLAMS to support the multipollutant measurements at that site.

Table 4.2-2 provides the Design Value and Sampling Frequencies for these sites.

Without both values submitted for exclusion, the threeyear Max 24-Hour Design Value would be 123 μg/m3; ratio of 0.82. NOTE: TEOM replaced FRM 2/19/2009. Design Value statistics includes data from FRM and TEOM monitors. 2 Hayden Old Jail - Several values have been flagged for exclusion as exceptional events, but these values are still included in the Design Value. If EPA concurs with the exceedances of 225 μg/m3, the Max 24-Hour Design Value would be 137; ratio of 0.91. NOTE: A TEOM replaced the FRM monitor beginning 4/1/2009. Design Value includes data from FRM and TEOM monitors. 3 Nogales Post Office – Exceedances for 2007 and 2008 are flagged for exclusion. Without the exceedance values of 190, 155, and 150 μg/m3 the three-year Max 24-Hour Design Value is 133 μg/m3; ratio 0.89. NOTE: A continuous monitor (BAM 1020) is operated at this site, but the Design Value statistics are from the FRM monitor only. 4 Paul Spur CLP – The exceedance for 2008 is flagged for exceptional event exclusion, but still included in the Design Value. Without the exceedance of 159 μg/m3, the three-year Max 24-Hour Design Value is 93 μg/m3; ratio of 0.62. 5 Prescott Valley – The first quarter of 2008 had less than 50% data completeness, which means the Design Value is not valid. 6 Rillito – The exceedance for 2007 and four high values for 2007-2009 have been flagged for exclusion as exceptional events, but these are still included in the Design Value. Without all of these values submitted for exclusion, the three-year Max 24-Hour Design Value would be 91 μg/m3; ratio of 0.61. NOTE: A TEOM replaced the FRM monitor beginning 4/1/2010. 7 Yuma Courthouse – The exceedances for 2009 and five high values for 2007 and 2009 have been flagged as exceptional events, but these are still included in the Design Value. Without these values the Max 24-Hour three-year Design Value would be 100 μg/m3; ratio of 0.67. NOTE: The FRM collocated monitors were closed 6/30/2009. The Design Value statistic is compiled from the FRM measurements (2007 through June 2009) and the continuous FEM (July-December 2009). The exceedances in 2009 were recorded by the continuous monitor. Also note monitoring in Yuma has been relocated to Yuma Supersite. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 19 4.3 O 3 Monitoring Network Requirements EPA modified the minimum monitoring requirements for O 3 in July 2009 (see Table 4.3-1). EPA also changed the length of the monitoring season for some states. The modifications also require each state to operate at least three O 3 monitors in non-urban areas. Table 4.3-1 Minimum Number of O 3 Monitors Required (40 CFR 58 Appendix D) Most recent 3 year 8hour Design Value ≥ Most recent 3 year 8Population (MSA) 85% of NAAQS (0.075 hour Design Value <85% ppm) or no Design NAAQS (0.075 ppm) Value available >10 Million 4 2 4-10 Million 3 1 350,000 - 4 Million 2 1 50,000 – 350,000 1 0 or 1* * NCore sites require a minimum of 1 monitor ADEQ operates a network of seven O 3 monitors throughout Arizona (see Table 4.3-2). Authority to operate O 3 monitors has been delegated to Maricopa, Pima, and Pinal counties. ADEQ will be relocating the Prescott College AQD monitor after the 2010 season due to siting requirements. ADEQ will also be looking for a suitable site in Lake Havasu City due to population requirements.

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 O 3 season for Arizona (April through October) based upon data collected from 1990-95. For 2007-09, the average number of days above 85% of the 2008 NAAQS of 0 .075 ppm continues to support the operation of seasonal monitors (see Figure 4.3-1). State of Arizona Air Monitoring Network Plan for the Year 2010, Page 20 ADEQ will operate the seasonal monitors from April 1st through October 31st. These 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.

New sites are not required because O 3 monitors are currently operated by the NPS at Grand Canyon National Park, Petrified Forest National Park, and Chiricahua National Monument in Arizona. ADEQ operates O 3 monitors at two non-urban sites: Alamo Lake and Tonto National Monument. ADEQ believes all of these sites meet the non-urban network requirement. 4.4 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 O 3 . Overall, only two sites are required for each area, providing all chemical measurements are made. Measurements include speciated VOCs, carbonyls, NO x , trace level nitrogen oxides (NO y ), CO, O 3 , 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 wind profiler site for the collection of upper air meteorological 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 State of Arizona Air Monitoring Network Plan for the Year 2010, Page 21 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 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 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 as part of the Five-Year Network Assessment due July 1, 2010. ADEQ also operates carbonyl, O 3 , NOx, and surface meteorological monitoring equipment at JLG Supersite (see Table 4.4-1).

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 VOCs, O 3 , and total reactive NOx. Carbonyl samples are not required at Type 3 sites. Table 4.4-2 lists the instrumentation and monitoring schedule at the Queen Valley site.

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 4.5-1. All required NCore monitors will be operational on or before 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.

State of Arizona Air Monitoring Network Plan for the Year 2010, Page 23 4.6 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 4.6-1 lists the ADEQ and source operated monitors used to determine SIP compliance. Table 4.6-1 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).

Some requirements are for 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 4.7-1 lists the monitors operated by ADEQ permitted sources.

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 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 4.8-1. An annual monitoring plan for this network is prepared by ADEQ. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 26 Table 4.8-1 2010-2011 Arizona Class I Visibility Monitoring Network Geographic Area Represented Monitoring Location Background Meadview, Organ Pipe National Monument Chiricahua National Monument, Chiricahua Chiricahua Entrance Station Wilderness Area and Galiuro USFS Wilderness Grand Canyon National Park Hance Camp and Indian Gardens Mazatzal and Pine Mountain USFS Wilderness Humboldt Mountain, Ike’s Backbone Mount Baldy Greer Water Treatment Plant Petrified Forest National Park Petrified Forest Saguaro National Park East Unit and West Unit Sierra Ancha USFS Wilderness Pleasant Valley Ranger Station Superstition USFS Wilderness Tonto National Monument, Queen Valley Sycamore Canyon USFS Wilderness Sycamore Canyon (Camp Raymond) 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 also established protocol sites (completely supported by ADEQ following IMPROVE monitoring requirements) to supplement 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. ADEQ is discontinuing operation of the nephelometers at nine Class I visibility sites in 2010 due to budget constraints. They are not required by the IMPROVE program, the CFR, or by the Regional Haze Rule SIP, and they have been funded solely by ADEQ. A wealth of data has been collected at each site and will be analyzed and summarized to characterize optical air quality for each Class I area represented. These results will be made available on ADEQ's website and the VIEWS website during the summer of 2010. See Table 3.4-1 for a list of the nephelometers to be closed. 4.9 Urban Haze Monitoring 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 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 State of Arizona Air Monitoring Network Plan for the Year 2010, Page 27 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, 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, two nephelometers for measuring light scattering, and a digital camera system operated by PDEQ to record visual characteristics of the urban area. The sites are described in Table 4.9-1.

Some sites were originally established because other meteorology networks (NWS, AZMet, etc.) were not located near ADEQ's ambient air quality sites. Review of the meteorological network will be done during the FiveYear Network Assessment. To help support exceptional event investigations, ADEQ is considering adding standard meteorological measurements to all of the air quality monitoring sites.

ADEQ's air quality forecasters use these data for daily forecast reports for Phoenix. This data reporting began for the Phoenix metropolitan area because continuous PM 2.5 instruments were not in operation. Since reporting began, Maricopa County Air Quality Department has begun operating several instruments and also begun reporting their data to AIRNow. Due to budget constraints, ADEQ closed its JLG Supersite nephelometer. A continuous PM 2.5 monitor operates at the site but is not reported to AIRNow. No other data from any ADEQ monitoring network is being submitted to AIRNow. ADEQ's Data Collection System (DCS) was modified several years ago to produce XML files in AIRNow format, when AIRNow was updating its system. However, AIRNow decided not to add the capability to accept XML files. ADEQ has no plans at this time to make modifications to DCS for AIRNow reporting. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 29 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 Performance Evaluation Program (PEP) and 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 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. 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, State of Arizona Air Monitoring Network Plan for the Year 2010, Page 30   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 currently composed of two full-time employees 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 Coordinator and AMU staff so that AAS is able to comment on pertinent QA changes that affect air monitoring quality, logistics, and resources. The QA Coordinator manages the PE audit program. In addition, the QA Coordinator 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 or QAPP) and/or Quality Assurance Project Plans (QAPjP or QAPPs) and SOPs 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. 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 2007, the QA/QC Manager submitted a QMP to EPA Region 9. Currently, the QMP is undergoing revision. 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 of the air monitoring programs AAS State of Arizona Air Monitoring Network Plan for the Year 2010, Page 31 operates. This document is being replaced by individual QAPPs 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 end dates. These can be more abbreviated documents. Since such projects involve multipollutant monitoring, these QAPjPs should refer to the appropriate QAPP for the pollutant to reduce duplication of effort. 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 2010, AAS is 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. The QA Team will also coordinate the development of a new QAPP for the new Pb monitoring program. The QA Coordinator will audit the new Pb sampler and ADEQ will participate 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 PM 2.5, PM 10 , Gaseous Pollutants, and Meteorological QAPPs. The QA Coordinator will manage PE audits on these instruments. AAS follows the EPA’s QAPP for the PM 2.5 STN monitoring program. In late 2009, a new URG 3000 sampler was added for the collection of elemental and organic carbon. The QA Coordinator will conduct PE audits on the SuperSASS and URG 3000 four times per year (quarterly) per instrument. An SOP for the URG 3000 is needed and planned for completion in 2010. SOPs for air monitors are provided 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 is drafting a new in-house guidance procedure for SOP management. The goal is to ensure each SOP contains all pertinent procedures from each Unit within 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 monitor 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. The Annual Audit Report and the annual Certification Letter contain more information on the AMP 255 report. The precision and bias data are reviewed for QA purposes by AMU and Data Management and Quality Assurance Unit (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. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 32 To date, the national air monitoring programs not currently accepting/requiring this precision and bias data include the CSN, NATTS, and PAMS. 5.2.1 Particulate Monitors – Manual Methods – PM 10 ADEQ currently operates one type of filter-based PM 10 samplers, which are partisols. All dichots samplers have been removed and are no longer used in any of ADEQ’s monitoring networks. Flow rate verifications are checked once every four weeks and instrument calibrations are performed every six months by AMU staff. The QA Auditor performs PE audits on these samplers once every six months. Concentration data from seven sites are reported to AQS in standard and local conditions. All sites are designated as SLAMS except Bethune. Section 3.3.1 of CFR Part 58 Appendix A indicates that 15 percent of the 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's has seven sites and according to the rule would need one collocated site. Currently ADEQ runs two collocated samplers, at Payson Well Site and Paul Spur Chemical Lime Plant, which complies 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 sixth day for precision measurements. 5.2.2 Particulate Monitors – Manual Methods – PM 2.5 The PM 2.5 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. ADEQ currently runs six PM 2.5 site, requiring one collocated site. This requirement is met with the collocation at Nogales Post Office site. ADEQ's six sites are designated as SLAMS. Concentrations 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 verifications are performed every four weeks and calibrations are performed once every six months by AMU. PE audits are conducted once every six months by QA. All precision and bias measurements are reported to the AQS. PEP audits are conducted on PM 2.5 monitors by EPA. The PEP audit results are used for measuring bias and are reported to AQS. The ADEQ network has more than five sites, which requires eight PEP audits distributed evenly over four quarters. All samplers should be audited within six years. 5.2.3 Gas Monitors – SO 2 , O 3 , CO, NO 2 One-point zero 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 are conducted by EPA annually for precision measurements. NPAP results are reported to AQS. Beginning in July 2010 these audits will increase and be conducted on a semi-annual basis. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 33 All shelters for the gas monitors contain temperature probes. The shelter temperature is checked daily via the DCS to verify proper operating conditions for the monitors. Shelter temperatures are required to be 20º to 30º C. Shelter temperature probes 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. AMU conducts verifications and calibrations on the samplers used to collect PM 10 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 will start being certified annually in 2010 by either ATEC or ERG. 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 every six months. 5.3 Calculations and Reporting ADEQ submits the required AQS precision and bias report (AMP 255) along with the Data Completeness Report to Region 9 in the annual Certification Letter per certification guidelines. As stated above, all collocated particulate mater (PM) measurements are submitted quarterly to AQS as POC 2. 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. 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 2009, the QA Team conducted TSAs of the Southern Regional Office (SRO) and Northern Regional Office (NRO) staff and operators. In 2010, the QA Team will provide support and assistance to AMU in addressing the findings and recommendations from the TSAs. To date, the QA Coordinator conducts TSAs on 11 IMPROVE samplers operating throughout the state annually. These TSAs are limited to evaluating site conditions and instrument performance with occasional operator interaction. Six of the 11 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 provided on EPA IMPROVE samplers. This will be reviewed in 2010 to determine if ADEQ can continue to support these unfunded audits. State of Arizona Air Monitoring Network Plan for the Year 2010, Page 34 In late 2009, the QA/QC Lead initiated the startup of an Air Toxics Team whose members include technicians from AMU, the QA Coordinator, and the data management lead. The purpose of this team is to prepare for a technical system audit and to update the NATTS/ATMP/PAMS QAPP and instrument SOPs. 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 PM 2.5 network to cause a shift in program performance over the last nine years. Based on EPA’s Three-Year Quality Assurance Reports for the SLAMS PM 2.5 Ambient Air Monitoring Program covering years 1999 through 2007, ADEQ's PM 2.5 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, and the PEP audit and data assessment process. To date, AFL has participated in two roundrobins in the Gravimetric Inter-Laboratory Comparison Study conducted by the EPA’s National Air and Radiation Environmental Laboratory (NAREL) and scored well on each. Further network evaluation will continue in 2010. 5.4.3 Technical Assistance Document Development In 2010, the process of verifying flow standards used by AMU and QA will undergo 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 O 3 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 2010, ADEQ will continue to participate in the EPA NPAP and the PM 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 2010 as in previous years. Also, PEP for Pb will begin this year 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 will be addressed in 2010 when the final report State of Arizona Air Monitoring Network Plan for the Year 2010, Page 35 is received. 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 will be addressed in 2010 when the final report is received.

The following was prepared by Region 9: Source-oriented lead (Pb) monitoring is required for the ASARCO copper smelter in Hayden, Arizona. ADEQ chose the Globe Highway Station site after an analysis that considered source emission characteristics, past monitoring, and the topography and meteorology of the facility location. A 1987 source apportionment study using the Chemical Mass Balance model concluded that 80% of the PM 10 Pb came from process fugitive emissions within the smelter ("Source Apportionment of Suspended Particles and Toxic Elements in Hayden, Arizona, Final Report", NEA Inc., April 15, 1987). Direct observation by ADEQ staff confirmed that particulate plume emanates principally from the smelter building itself, rather than from other sources such as ore handling facilities or re-entrained dust from storage piles. Because of the high temperatures involved in the smelting process, this plume is buoyant and has substantial vertical velocity, reaching to 100 feet or more above ground level. Unlike for non-buoyant ground level plumes, the highest ground level concentrations from such a buoyant plume would not be expected to occur immediately adjacent to the facility. Because the bulk of SO 2 emissions are also thought to be emitted as buoyant fugitives from the smelter building, 1970's monitoring of SO 2 is relevant for Pb. (Since the stack is 1,000 feet tall, SO 2 impacts from stack emissions occur farther away and are diluted by the time stack plume reaches the ground.) At that time SO 2 monitoring was conducted at twelve different monitor locations; Globe Highway Station was found to have the highest concentrations. Because of the similar emission characteristics of SO 2 and Pb fugitives, this suggests Globe Highway may also have the highest concentrations for Pb. The ASARCO Hayden smelter is located in very complex terrain, with the Gila River making a winding semi-circle east to south of the facility, and intersected by the San Pedro River valley from the south. The facility itself is elevated relative to the valleys; there is a 200 foot hill just south of the facility, and mountains rising toward the north/northeast. The varied terrain causes complex wind flow. Within and adjacent to the river valleys, drainage winds tend to dominate at night under stable conditions, toward the west on the south and west of the facility, and toward the south on the east of the facility. However, given the buoyancy of the smelter building fugitive plume, and the facility's elevated location, emissions typically rise above these surface flows and would not be expected to result in high Pb concentrations. During the day under convective conditions, good vertical mixing causes polluted air to reach the ground. The vertical mixing also causes the flow to be coupled with winds aloft, which generally flow toward the east. As was the case for SO 2 , these are the conditions expected to lead to high Pb concentrations and that also carry the plume east, toward the Globe Highway Station. Should placement of another Pb-TSP monitor be possible, EPA supports placement west of the smelter building, to capture winds moving east to west over the smelter area.
