### 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 Environmen tal Quality (ADEQ) to complete and submit to the U.S. Environmental Protection Agency (EPA) an annual network monitoring plan for the year 2009.

40 CFR, Part 51 requires states to create, submit, and adopt State Implementation Plans (SIPs) to address the various issues and responsibilities involved with creating and implementing air quality programs. Subpart J of Part 51 specifies that Part 58 Subpart B contains the requirements for establishing air quality surveillance systems to monitor ambient air quality.

Air quality surveillance systems consist of networks of monitors at carefully-chosen physical locations referred to as sites or stations. Some of the networks, sites, and monitors are:

 State and Local Air Monitoring Stations (SLAMS)

 National Core multipollutant monitoring stations (NCore)

 Photochemical Assessment Monitoring Stations (PAMS)

 Chemical Speciation Network (CSN)

 National Air Toxics Trends Sites (NATTS)

 Special Purpose Monitors (SPM)

 Urban Haze monitoring sites

 Interagency Monitoring of PROtected Visual Environments (IMPROVE)

 ADEQ visibility stations located in or near mandatory Class I areas (national parks and wilderness areas). Class I monitoring sites are subject to specific siting and operational guidance developed by the IMPROVE Steering Committee.

 AIRNow information sites

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

 Meteorological sites This Annual Monitoring Network Plan identifies th e purpose(s) of each monitor and provides evidence that both the siting and the operation of each monitor meet the requirements in 40 CFR Part 58 appendices A, C, D, and E as follows:

 Appendix A – Quality Assurance Requirements for SLAMS, SPMs, and PSD (Prevention of Significant Deterioration) Air Monitoring

 Appendix C – Ambient Air Quality Monitoring Methodology

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

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

Results of the annual network review and planning are used to determine how well the network is achieving its required air monitoring objectives, how well it meets data users’ needs, and how it should be modified (through termination of existing stati ons, 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 2009, Page 4 

### 2.0 PROGRAM AND NETWORK DESCRIPTIONS

Compliance Networks

The compliance networks operated by ADEQ are used to demonstrate compliance with several EPA programs. The largest compliance network in Arizona consists of monitoring sites operated for the purpose of demonstrating compliance with the National Ambient Air Quality Standards ( NAAQS ) for the “criteria” pollutants: carbon monoxide ( CO ), nitrogen dioxide ( NO 2 ), sulfur dioxide ( SO 2 ), ozone( O 3 ), particulate matter ( PM 10 and PM 2.5 ), and lead ( Pb ). In 2009, revised Pb monitoring requirements were added to the NAAQS: (1.) sources (by January 1, 2010) having annual ambient air emissions that are expected to exceed one ton a nd (2.) urban areas with population greater than 500,000 without regard to expected level of emissions. The criteria pollutants are measured using instruments that have been certified by the EPA as Federal Reference Methods (FRM) or Federal Equivalent Methods (FEM). CFR Part 58 specifies the minimum requirements for determining NAAQS compliance including the following network and site criteria:

 Number and types of monitors required per MSA by pollutant

 Objectives and spatial scales

 Sampling frequency

 Collocation and special NCore-related requirements

 Meteorology

 Probe location and other restrictions within a site

 Periodic performance evaluations

 Quality Assurance and data reporting

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

PAMS monitoring sites collect specified O 3 precursor concentrations as mandated by the 1990 Clean Air Act (CAA) Amendments. In addition, ADEQ participates in Federal grant programs such as NATTS and the CSN, which require their own monitoring networks. Data collected by these networks of monitors are used to assess and report pollutant concentrations, provide data used in modeling and SIP applications, track national trends, and monitor specific point-source emissions.

NCore Network

The NCore Multipollutant Monitoring Network is a nati onal network of monitoring sites that integrates multiple instruments, including some with trace-level capabilities, to provide representative measurements of area pollutants. NCore sites are required under 40CFR, Part 58, Appendix C – AMBIENT AIR QUALITY MONITO RING METHODOLOGY. Additional NCore information is available from the following EPA website: http://www.epa.gov/ttn/amtic/ncore/index.html

The NCore Monitoring Plan is included as Appendix F to this Monitoring Network Plan.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 5 SIP and Maintenance Area Networks

ADEQ maintains several air monitoring networks for the purpose of tracking compliance in areas that are currently not attaining one or more of the NAAQS or areas where the NAAQS have been met but on-going demonstration of compliance is required. Monitoring requirements for these areas are described in their associated SIPs.

Source Oriented Networks

Historically, ADEQ has required several of the major point sources in the state to conduct ambient monitoring for criteria pollutants, primarily PM 10 and SO 2 , in and around specific facilities. These monitoring networks constitute a subset of the compliance monitoring network described above. ADEQ activities with respect to these networks have been limited to regular performance audits and review of ambient data submitted by the individual sources. Recently, however, SIP support has required the submittal of data by some sources to the Air Quality System (AQS), including review of quality assurance documents kept by the sources to support their ambient monitoring programs. Sources located near Class I areas are being required to collect PM 2.5 data to assess impacts on visibility.

National Air Toxics Trend Sites (NATTS)

The NATTS network was designed to monitor and record the concentrations of certain air toxics on a national scale. ADEQ accepted federal funding and responsibility for this program in Arizona in 2003. Data from EPA’s national monitoring activities are used to estimate national average concentrations for these air toxics compounds and to detect trends. Usi ng this information, EPA, states, and local agencies can estimate changes in the risks of human exposure. These changes can then be used to support changes in environmental policy. As part of the National Air Toxics Assessment (NATA) process, ambient air quality data are used to assess the national toxics inventory and long-term hazardous air pollutant (HAP) trends. The ADEQ JLG Supersite is the designated NATTS site for the Phoenix metropolitan area.

Photochemical Assessment Monitoring Stations (PAMS)

Section 182(c)(1) of the 1990 CAA Amendments requires the Administrator to promulgate rules for enhanced monitoring of O 3 and concurrent monitoring of oxides of nitrogen (NOx), speciated volatile organic compounds (VOCs), 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 nonattainment areas classified as serious, severe, or extreme. The principal reasons for requiring the collection of additional ambient air pollutant and meteorological data are the widespread nonattainment of the 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.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 6 Chemical Speciation Network (CSN)

The CSN was established to meet the regulatory requirements for monitoring speciated 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) and has increased to 200 sites nationwide. Monitoring at JLG Supersite includes one STN speciation sampler and two IMPROVE samplers as part of the CSN network. The collocated IMPROVE samplers provide precision information for the IMPROVE network and are used for comparison of the speciation results from both programs. In 2009, the Met One SASS carbon channel on the STN speciation sampler will be replaced with a URG 3000N carbon sampler as part of the national program.

Urban Haze Networks

ADEQ operates an urban haze network in the Phoenix metropolitan area and provides funding for operation of the Tucson area network by the Pima Department of Environmental Quality. The purpose of the networks is to provide policy-makers and the public with information regarding urban haze levels, track short-term and long-term urban haze trends, assess source contributions to urban haze, and better evaluate the effectiveness of air pollution control strategies on urban haze. Equipment used to evaluate urban visibility includes transmissometers, nephelometers, particulate monitors, and digital camera systems.

Class I Area Network and IMPROVE Program

Visibility monitoring networks track impairment in specified national parks and wilderness areas. These parks and wilderness areas are called Class I Areas and were designated based on an evaluation required by Congress in the 1977 federal CAA Amendments. The evaluation, which was performed by the U.S. Forest Service (USFS) and National Park Service (N PS), reviewed the wilderness areas of parks and national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated across the nation, 12 are located in Arizona. Nine sites are located in USFS areas and three sites are located in NPS areas. From the Class I Area designations, EPA initiated a nationally-operated monitoring network in 1987 called the Interagency Monitoring of PROtected Visual Environments (IMPROVE) program. The purpose of the IMPROVE network is to characterize broad regional trends and visibility conditions using monitoring data collected in or near Class I Areas across the United States. ADEQ currently operates 11 sites with IMPROVE instrumentation.

AIRNow Reporting

ADEQ currently utilizes four urban nephelometers to approximate and report PM 2.5 data to the AIRNow Web site to provide near real-time data for public use. 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.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 7 Meteorological Network

ADEQ collects meteorological data at sites throughout th e state to provide weather information for those air quality monitoring sites not located near offici al weather-observing stations. Table 7.3-1 lists the sites and parameters measured in this network.

E-BAM Network of PM 10 & PM 2.5 Special Purpose Monitors

The current network of E-BAM continuous particulat e special purpose monitors (listed in Table 2.0-1) is composed of lightweight, portable monitors typi cally enclosed in self-contained, environmentally sealed containers. They can be battery or solar pow ered for operation at sites without fixed electrical power. E-BAMs continuously sample and report particulate concentrations. Data are sampled every second and concentrations recorded every minute. E-BAM monitors have been used by many agencies, particularly in the western United Sates, to provide continuous, real-time particulate concentration data that are very useful for making informed smoke management decisions related to prescribed burns. The Green Valley BAMs were replaced by E-BAMs in October, 2008. The E-BAM temporarily placed at Cottonwood will be moved to its permanent location in Camp Verde in 2009 when renovations to the site are complete. E-BAM instruments are used for special-purpose monitoring only. They are not classified as FRMs or FEMs and may not be used to demonstrate NAAQS compliance. Hourly data from the E-BAM monitors can be viewed at: http://www.phoenixvis.net/PPMmain.aspx

### 3.0 MONITORING NETWORK EVALUATION

This section describes ADEQ's current monitoring network and identifies monitors that are mandated by regulations, SIPs, maintenance plans, and grant requirements (such as NATTS). It also compares the status of the network to the EPA monitoring rules. Network changes - site and instrument, current and planned - are described in the following section and summarized in Section 3.2.

3.1 Network Changes

Site Closures

Prescott College AQD – The site does not meet site requirements because of the close proximity to tall trees and to a nearby road with a high traffic count. These conditions make the Prescott College site unsuitable for continued, long-term placement. In addition, environmental control issues (the instrument is in a room at the College that may not be temperature-controlled in summer months) have impacted the operation of the seasonal O 3 monitor. A search for a suitable site will begin in 2009 with the objective of moving the monitor to a new location before the start of the 2010 O 3 season.

Tucson U of A Central – The building that housed the site was demolished in 2009 and the site converted to a parking lot. The nephelometer, aethalometer, anemometer, and temp/RH monitors were removed and relocated to storage in Phoenix for potential future use. The aethalometer is not required for any current program and there are three other nephelometers in the Tucson area.

New Sites

Lake Havasu City – Kingman MSA – This area (population between 50,000 and 350,000) will require an O 3 monitor to be sited to capture maximum concentration in the MSA. That location will likely be in or near Lake Havasu City and a suitable site will be selected following careful analysis of the potential sites that will be identified by our search process and in accordance to O 3 network monitoring guidelines to be published by EPA in 2009.

Prescott College AQD replacement – A site will be selected from available sites in or near the city of Prescott and in accordance with O 3 network monitoring guidelines to be published by EPA in 2009.

Lead Source Network – EPA has identified two potential sites for implementation of the Pb monitoring rule: Hayden and Claypool-Miami, areas close to smelters. ADEQ, or its permitted sources, will be identifying locations for these monitors in 2009 in accordance with monitoring guidance to be published by EPA in 2009. In accordance with the November 12 th , 2008 revision of 40 CFR Part 58, Appendix A, paragraph 3.3.4.3, collocated TSP monitors will be required at the site with the “highest Pb concentrations in the network” - which would be Hayden if based on historical or National Emissions Inventory (NEI) data.

Ozone non-urban networks – The O 3 monitoring regulation requires three non-urban monitors in Arizona. New sites are not required because O 3 monitors are currently operated by the NPS at Grand Canyon National Park, Petrified Forest National Par k, and Chiricahua National Monument in Arizona.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 9 ADEQ operates O 3 monitors at two non-urban sites: Alamo Lake and Tonto National Monument. ADEQ believes these sites meet the non-urban network requirement.

Instrument Changes

Yuma Courthouse PM 10 and PM 2.5 Monitors – Access to the roof-mounted PM 10 and PM 2.5 monitors is considered dangerous and not suitable for continued operation. The monitors had previously been mounted on a different roof at the Courthouse which was considered adequate.

The collocated, filter-based PM 10 monitors are no longer required for NAAQS compliance following the addition of a continuous PM 10 TEOM in November 2007 and will be removed from this location. One of these, or an identical model filter-based PM 10 monitor, will be added to another site in the PM 10 network to meet minimum collocation requirements. The sites being considered for this collocation are Payson Well Site and Bullhead City. This change is planned for the end of June 2009.

The continuous PM 10 TEOM and the filter-based PM 2.5 monitors will be moved to a safer, more suitable location. The Yuma Supersite is considered the best choice to host the relocated monitors. This change is also planned for the end of June 2009.

Rillito PM 10 Monitor – The Rillito 24-hour design value for 2006-2008 places it in the category of every other day monitoring. ADEQ is considering inst allation of a TEOM at this site, but would be required to make extensive modifications to the site as well as obtain funding for purchase of a TEOM. This will be studied further in 2009.

JLG Supersite aethalometer – Review of monitoring programs indicate this instrument is not specifically required for any monitoring program and operation of this instrument will be discontinued in 2009. Data collected from this instrument and its predecessor, a less capable, single-beam model, that began operation in 1993, are currently being reviewed and will be reported to AQS.

JLG Supersite trace-level CO and SO 2 – These high-sensitivity instruments are required as part of NCore and will replace the current CO and SO 2 monitors used for NAAQS compliance following a period of concurrent operation. Data from these monitors will be reported to AQS.

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

JLG Supersite STN carbon channel – Being replaced by URG3000N as part of a national program to produce results more consistent with those from IMPROVE samplers.

Mexico Particulate Monitors – The Andersen dichot monitors were replaced with Thermo 2000D Partisol samplers in 2009. These monitors are now operated for ADEQ by a consultant.

Nogales Post Office PM 2. 5 – The Met One BAM 1020 will be upgraded in 2009 to an FEM model.

Rillito PM 10 – Replacement of the Partisol monitor with a TEOM is being investigated.3.2 Summary of Network ChangesTable 3.2-1 Monitors to be closed in 2009-10Site NameAQS IDClassificationScaleMonitorObjectiveParameter(s)MeasuredReportedto AQSReason for MonitorYuma Courthouse 04-027-0006 SLAMS Neighborhood MaximumconcentrationPM10, PM2.5Yes Population ExposureJLG Supersite 04-013-9997 SPMNeighborhood Visibility AethalometerYes Special Studies - Urban HazeJLG Supersite 04-013-9997 SLAMS/NCore Neighborhood OzoneprecursorNOy Yes Consistently very close to NOx during allseasonsPrescott College AQD 04-025-8033SPM Neighborhood Population Ozone Yes Required for MSATucson U of A Central 04-019-1027 UrbanHaze Neighborhood Visibility Aethalometer No Special Studies - Urban HazeTucson U of A Central 04-019-1027 UrbanHaze Neighborhood Visibility Nephelometer No Special Studies - Urban HazeTucson U of A Central 04-019-1027 SPM Neighborhood Visibility Wind No MeteorologyTucson U of A Central 04-019-1027 SPM Neighborhood Visibility Temp/RH No MeteorologyTable 3.2-2 Monitors to be Added 2009-10Site NameAQS IDClassificationScaleObjectiveParameter(s)MeasuredReport toAQSReason for MonitorJLG Supersite 04-013-9997 NCore Neighborhood Population Various Yes NCore NetworkYuma Supersite 04-027-8011 SLAMS Neighborhood Population PM10, PM2.5Yes NAAQS ComplianceMiami SLAMS Neighborhood Source Lead Yes Required by New RuleHayden SLAMS Neighborhood Source Lead Yes Required by New RuleLake Havasu City SLAMS Neighborhood Population Ozone Yes, in future Required for MSAPrescott SLAMS Neighborhood Population OzoneYes, in future Required for MSAState of Arizona Air Monitoring Network Plan for the Year 2009, Page 11 

### 4.0 REQUIRED MONITORING

4.1 EPA Minimum Network Requirements

Minimum monitoring activities required by the revised monitoring regulation are described in 40 CFR Part 58, Appendix D. In the revised monitoring rule, EPA removed minimum requirements for CO, SO 2 , NO, and Pb. A more recent revision set Pb concentration limits of 0.15 μ g/m 3 for sources expected to emit more than one ton per year and for urban areas with populations exceeding 500,000. The minimum monitoring requirements for ozone and particulat es are based upon MSA and Combined Statistical Areas (CSA) as defined in the most recent decennial census and the historical pollutant concentration in that area relative to the NAAQS. Tables 4.1-1 through 4.1-3 list the minimum monitoring requirements for PM 2.5 , PM 10 , and O 3

.

The NAAQS for O 3 was changed in March 2008 and includes a secondary standard for eight-hour O 3 (both standards are 0.075 ppm). EPA plans to provide updated O 3 monitoring guidance sometime in the second quarter of 2009. EPA revised the primary and secondary NAAQS for Pb on November 12, 2008. Both standards are set at 0.15 μ g/m 3

4.2 EPA Minimum Sample Frequencies

PM 2.5

The 40 CFR Part 58.12 (d)(1) states that manual PM 2.5 samplers at required SLAMS stations must operate on at least a one-in-three day schedule at sites without a collocated continuously operating PM 2.5 monitor. For SLAMS PM 2.5 sites with both manual and continuous PM 2.5 monitors operating, themonitoring agency may request approval from the EPA Regional Administrator for a reduction to onein-six day PM 2.5 sampling at SLAMS stations and also for seasonal sampling. The EPA Regional Administrator may grant sampling frequency reductions after consideration of factors including, but not limited to, the historical PM 2.5 data quality assessments, the location of current PM 2.5 design value sites, and their regulatory data needs. Sites that have design values that are within plus or minus 10 percent of the NAAQS (±10% of 35μg/m 3 is 31.5 to 38.5) and sites where the 24-hour values exceed the NAAQS for a period of three consecutive years are required to maintain at least a one-in-three day sampling frequency. Sites that have a design value within plus or minus five percent of the daily PM 2.5 NAAQS (±5% of 35μg/m 3 is 33.25 to 36.75) must have an FRM or FEM operating on a daily schedule.

ADEQ operates a PM 2.5 FRM sampler on the one-in-three day sampling frequency at one required SLAMS site, JLG Supersite. ADEQ also operates a non-FRM continuous PM 2.5 sampler (FDMS TEOM) at the site. Data from both monitors are reported to AQS. The data from the continuous monitor are reported to AQS using parameter code 88500 and began March 17, 2005.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 13 The Nogales Post Office PM 2.5 FRM sampler has a design value above the NAAQS and is operated on a one-in-six day sampling frequency. ADEQ also operates a non-FRM continuous PM 2.5 sampler (BAM) at the site. Data from both monitors are reported to AQS. The data from the continuous monitor are reported to AQS using parameter code 88501 and began March 2, 2005. ADEQ plans to upgrade the BAM sampler to FEM status. Nogales is the only nonattainment area for PM 2.5 in Arizona.

PM 10

The monitoring rule in 40 CFR Part 58.12 (e) states that for PM 10 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 PM 10 monitor to represent the area, such as Ajo, Hayden, and Yuma, sites can be considered de facto maximum-concentration sites whose operating frequencies must be determined using the Ratio-to-Standard diagram in 40 CFR Part 58.12 (e).

Table 4.2-2 lists the PM 10 design values for single monitor areas. Ajo, Hayden, and Rillito, require every-other-day monitoring and Yuma requires ever y-day monitoring. Since every-other-day collection (filters) would be economically and operationally impractical for ADEQ, continuous monitors will be used by ADEQ. Continuous monitors are operating at the Nogales Post Office (BAM monitor) and Yuma Courthouse sites, alongside the filter monitors. At Yuma Courthouse, the BAM monitor was replaced with a TEOM monitor in November 2007. All monitors at the Yuma Courthouse will be moved or discontinued (see Instrument Changes). TEOM monito rs were installed at Ajo and Hayden in the first quarter of 2009. A TEOM is being considered for installation at the Rillito site.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 14 Table 4.2-2 PM 10 Design Values and Sampling Frequencies of Maximum Concentration Monitors

4.3 ADEQ Minimum Network Status

The sections below address the minimum requirements for MSAs under the jurisdiction of ADEQ: Flagstaff, Yuma, Prescott, and Lake Havasu City - Kingman. Monitoring in the Maricopa-Pinal MSA and Tucson MSA will be addressed by Maricopa, Pinal, and Pima counties in their respective monitoring plans.

PM 2.5

According to Tables 4.1-1 and 4.1-4, the minimum PM 2.5 monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, and Flagstaff MSAs. Beginning in January 2008, filter based FRM monitors were added to ADEQ monitoring sites in Prescott and Yuma; Flagstaff has had an FRM monitor since the program began in 1999. Table 4.3-1 lists the most recent three-year average 98 th percentile design value concentrations for the existing ADEQ network of PM 2.5 monitors. Note: the Payson monitor was closed at the end of 2007 and moved to the Prescott Valley site since design values were well below the NAAQS and monitoring was no longer required.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 15 Table 4.3-1 PM 2.5 Design Values to determine Monitoring Requirements PM 2.5 Concentrations (μg/m 3 ) Most Recent Design Value for 3-Year Average 98 th Percentile (85% NAAQS is 29.75) Site MSA Represented Value Nogales Post Office (2006-2008) FR M None – Santa Cruz County 40 JLG Supersite (2006-2008) FRM Phoenix MSA 22 Douglas Red Cross (2006-2008) FRM None – Cochise County 15 Flagstaff Middle School (2006- 2008) FRM Flagstaff MSA 18 Prescott Valley FRM (began 1/1/2008) Prescott MSA 12* Yuma Courthouse FRM (began 1/1/2008) Yuma MSA 21* * Values shown are annual design values, not 3-year design values since the sites were installed in 2008.

ADEQ operates non reference method PM 2.5 continuous monitors at Nogales Post Office (BAM) and JLG Supersite (FDMS TEOM).

PM 10

According to Tables 4.1-2 and 4.1-4, the minimum PM 10 monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, Flagstaff, and Lake Havasu City-Kingman MSAs. They all fall under the 100K-250K population category for PM 10 monitoring. ADEQ currently operates one or more FRM filter-based PM 10 samplers in each MSA.

Prescott MSA (Yavapai County) – ADEQ has operated a reference method PM 10 sampler at Prescott Valley since March 2003. The maximum 24-hour value recorded over the last three years (2006-2008) of operation is 63 μg/m 3 , approximately 42 percent of the NAAQS. Therefore, the site is considered a low category as described in Table 4.1-2 and the single monitoring site at Prescott Valley is adequate to meet the rule requirement.

Yuma MSA (Yuma County) – ADEQ currently operates a reference method PM 10 sampler at the Yuma Courthouse, operating on a one-in-six day schedule. A continuous PM 10 monitor is also operated at this site to meet the every-day frequency required. The site is also required under the current SIP Maintenance Plan described in additional detail in section 4.3 of this document. Maximum 24-hour concentrations recorded in 2006, 2007, and 2008 were 151, 147, and 92 μ g/m 3 . The area is considered to be in the medium category and this monitoring site in Yuma is adequate to meet the rule requirement. This site (all instruments) will be relocated in 2009 (cf. tables 3.2-1 and 3.2-2).

Flagstaff MSA (Coconino County) – ADEQ has operated PM 10 samplers at two sites in the Flagstaff MSA (Flagstaff Middle School and Sedona Post Office since 1992). In 2000-2008, the maximum 24- hour concentration recorded at Flagstaff Middle School was 56 μ g/m 3 (37 percent of the NAAQS); the maximum concentration at Sedona Post Office was 36 μg/m 3 (24 percent of the NAAQS). Both sites are less than 80 percent of the PM 10 NAAQS. Therefore, the sites are considered low category and a single monitoring site in the MSA is adequate to meet the rule requirement. Since the Sedona Post Officemonitor has a long record of low values, it was closed in December 2007 and replaced with a nonreference method E-BAM continuous sampler. ADEQ will continue operation of the Flagstaff MiddleState of Arizona Air Monitoring Network Plan for the Year 2009, Page 16 School PM 10 monitor in 2009. A non-reference method E-BAM continuous sampler was installed at the Flagstaff Middle School site to provide con tinuous measurements for public information.

Lake Havasu City-Kingman MSA (Mohave County) – ADEQ has operated a PM 10 monitor at Bullhead City since September, 2003. In the 2006-2008 period, the maximum value was 72 μg/m 3 and the design value to max ratio was 0.48 verifying the correctness of the 1-in-6 frequency. The Bullhead City monitor is required because it is in a maintenance area.

Ozone According to Tables 4.1-3 and 4.1-4, the minimum O 3 monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, Flagstaff, and Lake Havasu City-Kingman MSAs. All are in the 50K-350K population category.

Yuma MSA (Yuma County) – ADEQ closed the Yuma Game and Fish monitor at the end of the 2008 monitoring season due to logistical problems beyond ADEQ's control. ADEQ reopened the Yuma Supersite SLAMS (used during the Western Ariz ona Sonora Border Air Quality Study in 2006-2007) and operated an O 3 monitor there during the 2008 season beginning in May for data comparison and is now the only site in this MSA.

Prescott MSA (Yavapai County) – ADEQ operated an O 3 monitor in Prescott from 1981-1984 and reported the data to AQS. The design value during this period was 0.062. ADEQ also operated a monitor at Hillside from 1996 through the 2005 season. The design value for 2003-2005 was 0.072 ppm, which exceeds 85 percent of the eight-hour NAAQS. However, the Hillside site represented upwind transport of O 3 into the central Arizona and did not, by design, represent the Yavapai County or Prescott MSA population. Because an adequate data record did not exist to represent the MSA, ADEQ established an SPM O 3 monitoring site at Prescott College with measurements beginning April 1, 2008. This site will be relocated when a suitable site is found.

Flagstaff MSA (Coconino County) – ADEQ operated O 3 monitors at three sites in the Flagstaff MSA from 1977 through 1985 and reported the data to AQS. The most recent design value from 1983-1985 data was 0.071 ppm. The NPS has been operating an O 3 site at the South Rim of the Grand Canyon since approximately 1990. The latest data available from that site indicates a three year average of the fourth highest eight-hour concentration of 0.077 ppm in 2005-2007 at this monitor, which is above 85 percent of the NAAQS. Because it has been over 20 years since ADEQ collected O 3 data in the city of Flagstaff, ADEQ added an SPM O 3 instrument to the Flagstaff Middle School site for comparison with NPS data. Measurements began April 1, 2008.

Lake Havasu City-Kingman MSA (Mohave County) – Following future site selection and installation, ADEQ will monitor O 3 at this site.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 17 Ozone Season

In accordance with 40 CFR Part 58, Appendix D, Para graph 4.1(i), ADEQ was granted a modification to the January through December O 3 season defined in the regulation. The 1998 EPA guidance document entitled, “Guideline for Selecting and Modifying the Ozone Monitoring Season Based on an Eight-Hour Ozone Standard” supports a shorter O 3 season for Arizona based upon data collected from 1990 through 1995.

Figure 4.3-1, a summary of data from the sites operated by ADEQ, illustrates that O 3 concentrations have not typically exceeded 85 percent of th e NAAQS during the period from November through February and only occasionally in the month of March.

ADEQ will operate the seasonal monitors from April 1st through October 31st. These site are: Alamo Lake, Queen Valley, Yuma Supersite, Tonto Nationa l Monument, Flagstaff Middle School, and Prescott College AQD. The JLG Supersite will continue to operate on a January to December schedule.

PAMS

The Arizona PAMS network consists of two ambien t air monitoring sites in the Phoenix MSA and a wind profiler site for the collection of upper air mete orological data. VOC and carbonyl samplers collect ambient air in hydrocarbon (HC) canisters and in cartridges containing silica substrate impregnated with acidified 2, 4-Dinitrophenylhydrazine (DNPH), respectiv ely, which are routinely analyzed for chemical constituents. The Phoenix area PAMS sites and monitors are described below.

JLG Supersite – Type 2 PAMS Site: 17th Ave. & Campbell, Phoenix. The JLG Supersite was designated a PAMS site in 1999. To meet the revised EPA requirement for daily monitoring, ADEQState of Arizona Air Monitoring Network Plan for the Year 2009, Page 18 contracted with an outside vendor for the operation of an automated gas chromatograph mass spectrometer (Auto GC/MS) monitoring system for co llection and analysis of PAMS VOCs data at JLG Supersite for the 2007 monitoring season. The hourly data were reviewed and submitted to AQS. A comparison with the canister samples collected for Toxics VOCs indicated the Auto GC/MS measurements were within 15 percent of the canister method results. Analysis of the 2007 results has been completed and the successful operation of the Auto GC/MS and the reliability of the results for analysis plus the additional information that continuous measurements can provide could support a decision to purchase an Auto GC/MS to be operated at JLG Supersite during PAMS season in lieu of canister sampling. However, consultation with current users of Auto GC equipment in several different agencies confirmed that purchase and installati on would cost approximately $100,000 and successful operation would require half an FTE on a continuing basis. Since the required manual method of eight three-hour canisters running daily is impractical due to increased expenses for staff, shipping, and analysis, ADEQ plans to return to the 2006 monitoring schedule of a 24-hour canister sample everysixth day at the JLG Supersite during PAMS season for VOCs. This will be reviewed as part of the fiveyear Network Assessment due July 1, 2010. ADEQ also operates carbonyl, O 3 , NOx, and surface meteorological monitoring equipment at JLG Supersite (see Table 4.3-2).

4.5 Source Compliance Network

Historically, ADEQ has required several of the major point sources in the state to conduct ambient monitoring for selected criteria pollutants in and around specific facilities. ADEQ activities with respect to these networks have been limited to regular perfor mance audits and review of ambient data. Recently, ADEQ has begun to submit a portion of these data to the EPA AQS database to support SIP compliance. Sources are required to review these data and submit quality assurance documents to ADEQ with the data.

Table 4.5-1 describes the current source operated network. This monitoring plan does not intend to implement changes to these networks. The mechanism to alter these networks is through the permitting process in consultation with ADEQ's Permits and Planning Sections.

4.6 Compliance with 40 CFR Part 58.10 (c)

A process for relocating violating PM 2.5 monitors is described at 40 CFR Part 58.10 (c). The rule requires that the annual monitoring network plan must document how state and local agencies provide for the review of changes to a 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 of this chapter. The affected state or local agency must document the process for obtaining public comment and include any comments received through the public notification process within their submitted plan.

ADEQ does not intend to establish community monitoring zones as described in the rule or utilize spatial averaging for comparison to the 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. 2. Make notice of such a change in the annual monitoring plan. 3. If the change must be accomplished prior to annual monitoring plan submittal, ADEQ will make appropriate notice via the agency Web page and invite participation from the public prior to relocation of the affected site. 4. Relocation of affected monitor.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 22 

### 5.0 MONITORING PLAN QUALITY ASSURANCE

5.1 40 CFR Part 58 Appendix A – Quality Assurance Requirements

Appendix A specifies the quality assurance requirements for SLAMS, SPMs, and PSD Air Monitoring. It describes requirements for the quality system, measurement quality checks for the monitors, calculations for data quality assessments, and reporting requirements.

5.2 Quality System Requirements

ADEQ is the Primary Quality Assurance Organization (PQAO) for the monitors it operates. The Quality Assurance (QA) Team is in the Data Management & Quality Assurance Unit in the Air Assessment Section along with the Air Monitoring Unit. The QA Team has several responsibilities to ensure a quality monitoring program is operated by ADEQ:

 coordinating the preparation of the Quality A ssurance Project Plan (QAPP) documents and Standard Operating Procedures (SOPs) for monitoring programs and projects,

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

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

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

Quality Documents

ADEQ has a Quality Management Plan in place for the agency that was completed in August 2005. Air Assessment submitted a Quality Assurance Project Plan to EPA Region 9 in November 2001. ADEQ uses the QAPPs prepared for EPA for the IMPROVE and STN monitoring programs.

ADEQ's revised National Air Toxics Trends Stations, Air Toxics Monitoring Program, & Photochemical Assessment Monitoring Stations QAPP (submitted September 2007) was approved by EPA Region 9 in February 2008.

A QAPP was prepared for the PM 2.5 program when it began in 1999. Updates to the QAPP were submitted to Region 9 in August 2006. QA Plans for gases and particulate matter are next for revision and may be combined into a single project plan document. All instrument SOPs have been completed and submitted to EPA Region 9.

Audit Team Responsibilities

The QA Team conducts performance audits of Air Assessment monitors, Pinal County monitors, and some source monitors. All gas and flow rate standards used by the QA teams are traceable to NIST. Standards are checked annually. The gas calibrator and O 3 standard used by the Team are checked twice

per year.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 23 The QA Team conducts technical system audits of the ADEQ Filter Laboratory. The QATeam has updated the SOP used for TSAs of ADEQ's Filter Laboratory.

The Team has prepared procedures for conducting TSAs of the Southern Regional Office (SRO) and Northern Regional Office (NRO) staff who act as operators for the Monitoring Unit.

The Team conducts performance audits of 11 IMPROVE samplers. ADEQ will conduct TSAs on only the 6 protocol samplers. Two samplers per year will receive the TSA.

EPA Audit Responsibilities

ADEQ has agreed to participate in the EPA National Performance Audit Program (NPAP) and the PM Performance Evaluation Program (PEP). ADEQ has consented to have EPA use a portion of ADEQ's grant funds to conduct these audit programs through IFC Consultants. NPAP and PEP audits are expected to occur in 2009/2010.

EPA Region 9 conducted a TSA of the Air Assessment Monitoring Program in December 2004. The next TSA is scheduled for September 2009. A TSA of the NATTS station was initially planned for January, 2009, but it has been postponed indefinitely.

ADEQ’s filter lab participated in EPA’s (OAQPS) Inte r-Lab (round-robin) testing with excellent results that may be obtained from OAQPS.

5.3 Measurement Quality Checks – Precision Measurements

5.3.1 Particulate Monitors – Manual Methods – PM 10

ADEQ operates two types of PM 10 samplers with different methods: dichots and partisols. The dichots are located at the two Mexico locations. Because the dichot samplers in Mexico are not collocated, precision data are not collected for this method. PM 10 concentrations from the dichot samplers are reported to AQS designated as monitor type 'Other'. In 2009, the Anderson dichots were replaced by Thermo 2000-D Partisol samplers. Data are reported to AQS in standard (81102) and local conditions (85101).

The partisol samplers are located at 10 sites. Concentration data from all 10 sites are reported to AQS in standard and local conditions. All sites are designated as SLAMS. Section 3.3.1 of CFR Part 58 Appendix A indicates that 15 percent of the sites must be collocated. The collocated monitors must be within four meters of each other and at least one meter apart for flow rates less than 200 liters/min. ADEQ's collocated samplers are listed in Table 5.3-1 and comply with these requirements. All concentrations from the collocated samplers are reported to the AQS with parameter occurrence code (POC) 2.

Collocated samples are collected every 6th day for precision measurements. Flow rate verification is checked monthly and instrument calibrations are performed twice a year by Monitoring Unit staff.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 24 Table 5.3-1 PM 10 Precision Monitoring by Method

Sampling Method Total Number of Sites Number of Precision Sites

Dichot 2 (Mexico) 0 Partisol 10 2 (Paul Spur & Yuma Courthouse*) *Collocated site will be moved in 2009 to either Payson Well Site or Bullhead City.

ADEQ will continue to report PM 10 concentrations to AQS for three monitors at two sites (Miami Ridgeline and Golf Course-collocated site) designated as 'Industrial' to support SIP requirements for the Miami attainment area. These monitors are operated by the Freeport-McMoRan (formerly Phelps Dodge Corporation) as a permit requirement. Freeport-McMoRan supplies flow check and calibration reports to ADEQ which conducts performance audits to verify adherence to quality assurance procedures.

5.3.2 Particulate Monitors – Manual Methods – 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. The total number of sites shown in Table 5.3-2 includes all PM 2.5 samplers in the ADEQ network (this excludes sites operated by County and Tribal agencies).

Table 5.3-2 PM 2.5 Precision Monitoring Sampling Method Total Number of Sites 1 Number of Precision Sites FRM (R&P partisols) 6 2 (Nogales Post Office & JLG Supersite)

1 Excludes sites operated by Tribal Programs, Ma ricopa County, Pima County, and Pinal County.

All six ADEQ sites (Douglas Red Cross, Flagstaff Middle School, JLG Supersite, Nogales Post Office, Prescott College AQD, and Yuma Courthouse) are de signated as SLAMS. Concentrations from all samplers are reported to AQS. All concentrations from the collocated monitors are reported as POC 2.

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

measurements.

Flow rate verification is checked monthly and inst rument calibrations are performed twice a year by Monitoring Unit staff.

5.3.3 Gas Monitors – SO 2 , O 3 , CO, NO 2

One-point zero span checks are conducted biweekly a nd multipoint calibrations are performed quarterly by the monitoring staff for all gas monitors. These measurements are reported to the AQS.

NPAP through-the-probe audits are conducted annually for precision measurements.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 25 All shelters for the gas monitors contain temperature probes. The shelter temperature is checked daily via the Data Collection System to verify proper operating conditions for the monitors. Shelter temperatures are required to be 20o to 30o C.

5.4 Measurement Quality Checks – Accuracy Measurements

5.4.1 Particulate Monitors – Manual Methods

The QA Team conducts semi-annual performance evaluation audits (flow rate audits on ADEQ PM 10 and PM 2.5 monitors). All accuracy measurements are reported to the AQS. PEP audits are conducted once a year by EPA and used for measuring bias.

5.4.2 Gas Monitors – SO 2 , O 3 , CO, NO 2

The QA Team conducts annual audits of all gas monitors. These are multi-point performance evaluation audits. The audit measurements are reported to the AQS. When the NCore program is implemented in July 2010 the audits will increase and be conducted on a semi-annual basis.

5.4.3 Meteorological Equipment

Meteorological equipment is audited by the QA Team annually. The meteorological equipment at the designated NCore site will be checked twice per year.

5.5 Calculations and Reporting

ADEQ submits the required AQS precision and accuracy report along with the Data Completeness Report to Region 9 in the annual Certification Letter per certification guidelines. As stated above, all collocated PM measurements are submitted quarterly to AQS as POC 2, with an indication of which monitor is the primary. AQS then calculates the precision statistics. The gaseous biweekly checks are submitted quarterly as precision records. Audit information for both PM monitors and gas monitors are also submitted quarterly.

The QA Team has developed a method following EPA guidelines for performing the calculations described in Section 4 of CFR Part 58 Appendix A on a regular schedule.

5.6 Ambient Air Quality Monitoring Methodology

ADEQ meets the required monitoring methodology for monitors used in compliance applications. A complete description of monitoring methods by site and monitor is located in section 6.0 of this document.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 26 5.6.1 Monitoring Objectives and Spatial Scales

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

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

 Support compliance with ambient air quality standards.

 Support air pollution research and strategy development.

To meet these objectives, the design of ambient air monitoring networks must consider the physical and chemical behaviors of the individual pollutants - in cluding properties such as transport and dispersion. The locations of a network’s monitoring stations are selected to achieve one or more of the six basic objectives specified in 40 CFR Part 58 Appendix D: 1. Determine the highest concentrations expected in the area covered by the network. 2. Measure representative concentrations in areas of high population density. 3. Determine the impact of significant sources or source categories on air quality. 4. Determine general background concentration levels. 5. Measure regional pollution transport among populated areas. 6. In support of secondary standards, to determine the welfare-related impacts in more rural and

remote areas.

Appendix D of 40 CFR Part 58 provides guidance concer ning spatial scales of air parcels in which the pollutant concentration is reasonably similar. Monitoring stations are sited in one of the following scales of representativeness: microscale, middle scale, neighborhood scale, urban scale, or regional scale (see Table 5.6.1-1). The scale is usually chosen based on the pollutant to be monitored; however, it may be determined by the site objective as in the case of monitoring O 3 levels downwind of a major metropolitan area.

Table 5.6.1-1 Scale of Representativeness Scale of Representativeness Dimension Micro several meters up to 100 meters Middle 100 meters up to 0.5 kilometers Neighborhood 0.5 kilometers up to 4 kilometers Urban 4 kilometers up to 50 kilometers

Regional rural areas or cities of homogeneous geography; can extend from tens to hundreds of kilometers

5.6.2 General Monitoring Requirements

 NCore Multipollutant Site – ADEQ JLG Supersite will be designated as an urban NCore site in the timeframe specified in the revised 40 CFR Part 58. The scale of this site is neighborhood, which complies with the recommendations in Part 58. Continuous monitoring methods will be employed where available. The data will be reported (AQS) and made available for air quality trends analyses, model evaluation, and NAAQS compliance.

 SLAMS – Although Part 58 states that SLAMS sites, other than NCore, are intended to address specific air quality management interests and are frequently single-pollutant measurement sites, many of ADEQ’s SLAMS sites are multipollutant for several reasons including the size ofADEQ’s territory and the economic benefits achieved when such sites meet multiple pollutantobjective requirements.

5.6.3 Pollutant-Specific Design Criteria for SLAMS Sites

See also section 4.3 ADEQ Minimum Network Status in this document for specific information on the monitoring networks in three MSAs under ADEQ jurisdiction: Flagstaff, Prescott, and Yuma. The following sections include more general pollutant-specific design criteria.

 Ozone – More than the specified minimum could be required to support public data reporting, air quality mapping, compliance, and O 3 -related research. This is particularly true of the PhoenixMesa-Scottsdale MSA that includes Maricopa a nd Pinal Counties but not of the Flagstaff, Prescott, or Yuma MSAs. Factors considered were the MSAs geographic sizes, population densities, meteorology, terrain, air transport, and the presence of O 3 precursors. Section 3.2 provides background information on the current and historical O 3 monitoring sites. EPA is preparing revised O 3 monitoring guidance requirements for the new NAAQS. Written guidance has not been received from EPA to date. The frequency of performance evaluation audits will increase to twice per year at the NCore monitoring site when the program is implemented. ADEQ will continue to participate in the NPAP program as well.

 Carbon Monoxide – There are no minimum requirements for the number of CO monitoring stations, but continued operation of existing sites is required – the JLG Supersite, in this case. In addition, where SLAMS (and, presumably NCore) CO monitoring is ongoing, at least one siteState of Arizona Air Monitoring Network Plan for the Year 2009, Page 28 must be maximum concentration. At present, the CO monitoring objective at the JLG Supersite is population, but other sites in the Phoenix MSA combine to meet the maximum concentration requirement.

 Nitrogen Dioxide – There are no minimum requirements for NO 2 but existing sites must continue to monitor unless authorized by the Regional Administrator to be discontinued. As with continued CO monitoring, continued NO 2 monitoring implies that at least one NO 2 monitoring site must be a maximum concentration site. The JLG Supersite objective for NO 2 monitoring is population, but other sites in the Phoenix MSA combine to meet the requirement.

 Sulfur Dioxide – There are no minimum requirements for SO 2 but existing sites must continue to monitor unless authorized by the Regional Administrator to be discontinued. ADEQ monitors SO 2 emissions at the JLG Supersite and at several mining sites.

 Lead – The new Pb standard is 0.15 μ g/m 3 . Source-oriented Pb monitoring is planned for two sites (Hayden and Miami). Non-source-oriented monitoring is being performed as part of the PM 10 metals (NATTS) data collection.

 Particulate Matter (PM 10 ) – Refer to section 4.3 ADEQ Minimum Network Status

.

 Fine Particulate Matter (PM 2.5 ) – Refer to section 4.3 ADEQ Minimum Network Status

.

 Coarse Particulate Matter (PM 10 -PM 2.5 ) – The ADEQ NCore site will meet requirements.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 29

7.1 Class I Visibility Network Visibility monitoring networks track impairment in specified national parks and wilderness areas. These parks and wilderness areas are called Class I Areas and were designated based on an evaluation required by Congress in the 1977 federal CAA Amendments. The evaluation which was performed by the U.S. Forest Service (USFS) and National Park Service (N PS) reviewed the wilderness areas of parks and national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated across the nation, 12 are located in Arizona.

From the Class I Area designations, EPA initiated a nationally-operated monitoring network in 1987 called the I nteragency M onitoring of PRO tected V isual E nvironments (IMPROVE) program. The purpose of the network is to characterize broad regional trends and visibility conditions using monitoring data collected in or near Class I Areas across the United States. Originally the national IMPROVE network was made up of approximately 30 sites at Class I areas; during 1999-2000 the number of sites increased to approximately 110. In 1996 ADEQ began to add monitoring sites in or near Class 1 areas in the state in order to supplement the IMPROVE network.

The Arizona Class I Visibility Network consists of a combination of visibility monitoring sites established by ADEQ and those established by the IMPROVE committee. Monitoring for this purpose is conducted at the sites described in Table 7.1-1. Table 7.1-2 describes supplemental monitoring conducted by ADEQ to support the IMPROVE program and Regional Haze planning and technical analysis.

7.2 Urban Haze Network

ADEQ monitors the Phoenix and Tucson metropolitan areas with a network of instruments to characterize and quantify the extent of urban haze. There are no established federal or state standards for acceptable levels of urban haze. ADEQ began studying the nature and causes of urban hazes by conducting a study in the winter of 1989-90 in Phoe nix and the winter of 1992-93 in Tucson. These studies recommended long-term, year-round monito ring of visibility. In 1993, ADEQ began deploying visibility monitoring equipment in Phoenix and Tucson. These visibility monitoring data are needed to provide policymakers and the public with information, track short- and long-term trends, assess source contributions to urban haze, and better evaluate the effectiveness of air pollution control strategies. Equipment used to evaluate urban visibility includes transmissometers, nephelometers, aethalometers, particulate monitors, and digital camera systems.

The Phoenix urban haze network includes two transmissometers (located in Phoenix and Mesa) for measuring light extinction along a fixed path lengt h of about three to five kilometers, four nephelometers for measuring light scattering, six digital camera systems to record visual characteristics of the urban area, and particulate filters for quantifying and characterizing particulate matter. The Tucson urban haze network includes one transmissome ter for measuring light extinction along a fixed path length of about three to five kilometers, three nephelometers for measuring light scattering, and a digital camera system operated by Pima County to record visual characteristics of the urban area. The sites are described in Table 7.2-1.

7.3 Meteorology Network

ADEQ collects meteorological data to provide weather information for the monitoring sites not located near official weather stations. Much of the equipment is located at visibility monitoring sites. Two locations collect data used to meet PAMS meteor ological requirements. All meteorological data (with the exception of profiler and sodar measurements) r eceive two levels of quality assurance checks. The equipment is audited annually. The sites and instrumentation operated by ADEQ are listed in Table 7.3- 1.State of Arizona Air Monitoring Network Plan for the Year 2009, Page 34Table 7.3-1 Meteorology NetworkSiteTemperatureTemperatureLapse RatesystemRelativeHumidityWindTotalHorizontalSolarRadiationUltravioletSolarRadiationWindProfilerReport toAQSComments22nd St./Craycroft X X NoAgua Prieta Fire Station X X X NoAjo X NoChildren's Park X X NoChiricahua Entrance Station X X NoDysart X X NoEstrella X X NoGrand Canyon NP – IndianGardenX XGreen Valley FireAdministrationXGreer Water Treatment Plant X X X NoIke's Backbone X X X NoJLG Supersite X X X Yes For PAMS supportMesa TransmissometerReceiver (Mesa City Building)X XNoNogales Post Office X NoOrgan Pipe NM X X NoPaul Spur Chemical Lime Plant- SouthXNoPayson Well Site X X X NoPetrified Forest National Park X XPhoenix TransmissometerReceiver (Holiday Inn Hotel)X XNoPleasant Valley X X X NoQueen Valley X X No For PAMS supportRillito X NoSaguaro Ntl Park West X X X NoSycamore Canyon X X X NoTucson TransmissometerReceiver (Pima County Health& Welfare Bldg.)X XNoTucson U of A Central X X X NoVEI X X X X X X X Solar only For PAMS supportYuma Agri Center Farm X X X NoYuma Mesa X X X NoState of Arizona Air Monitoring Network Plan for the Year 2009, Page 35

## Appendix F – 2009 ADEQ NCore Monitoring Plan

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

JLG Supersite has a long history of multi-pollutant monitoring beginning in 1993 with the National Ambient Air Quality Standards ( NAAQS) . Photochemical Assessment Monitoring Stations ( PAMS ) and Chemical Speciation Network ( CSN ) were added in 1999 and National Air To xics Trends Sites ( NATTS) in 2001. JLG Supersite also hosts collocated IMPROVE monitors and other instruments including Hexavalent Chromium, Speciated VOC (PAH ), and meteorology. Trac e-level carbon monoxide and sulfur dioxide instruments are being tested and readied for installation. All required monitoring (with the exception of PM10-2.5 speciation) will be operational on or before January 1, 2011. A NOy waiver request and justificat ion are included in this appendix.

JLG Supersite is housed in two climate-cont rolled shelters in an urban neighborhood not overly influenced by local or topographical conditions. Ample exterior space is provided by the platform covering the two shelters and the sp ace between them. A ten-meter tower is anchored to the platform. Multiplexed digital communications between this site and ADEQ’s Phoenix office are being implemented as part of NCore modifications.

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

State of Arizona Air Monitoring Netw ork Plan for the Year 2009, Page 2JLG Supersite Site Purpose : NAAQS compliance network, PAMS, NATTS, CSN, NCORE, AIRNow, AQI forecasting, monitor urban haze, and meteorological support.

The site was established to represent air quality in the central core of the Phoenix metropolitan area. The surrounding area is primarily residential ne ighborhoods, with I-17 roughly 1,609 meters west.

State of Arizona Air Monitoring Netw ork Plan for the Year 2009, Page 11State of Arizona Air Monitoring Netw ork Plan for the Year 2009, Page 12 Request for NOy Waiver

As stated in the NCore Readiness Self-Assessment fo r State/local/Tribal Agencies document , “Although the measurement of NOy is required in support of a number of monitoring objectives, available commercial inst ruments may indicate little difference in their measurement of NOy compared with the conven tional measurement of NOx, particularly in areas with relatively fresh sources of nitrogen emissions. Therefore, in areas with negligible expected diffe rence between NOy and NOx measured concentrations, the Administrator may allow for waivers that permit high-sensitivity NOx monitoring to be substituted for the required NOy monitoring at applicable NCore sites.”. This is the case with NOy and NOx at the JLG Supersite NCore site. The Thermo instrument used to measure NOx is sensitive to 0.05 parts-per-billion.

A comparison of the 2008 NOy and NOx concen trations at Supers ite during the 2008 ozone season (April – October) shows a difference of less than 2% for the entire season. This indicates that only very small concen trations of the NOz components of NOy are present at JLG Supersite. NOz components resu lt from the atmospheric oxidation of NOx and include nitric acid (HNO 3 ), nitrate radical (NO 3 ), peroxyacetyl nitrates (PAN), and many others.

As a result of the above comparison showi ng the small difference between NOx and NOy at JLG Supersite, NOy will not be sampled and the NOx measurements can be used in lieu of NOy.

Pb-PM 10 Non-Source-Oriented Monitor at NCore Site (JLG Supersite)

Paragraph 4.5(b) of Part 58 Appendix D specifies that the use of a Pb-PM 10 monitor can be used instead of a TSP monitor “if no ex isting monitoring data indicating that the maximum arithmetic 3-month mean Pb concentr ation...was equal to or greater than 0.10 micrograms per cubic meter during the past thre e years.” That is certainly the case at JLG Supersite. In fact, in the pa st three years the highest maximum value (which is always greater than the highest mean value) wa s only 0.017 micrograms per cubic meter – less than 20% of 0.10. While non-source-oriented lead monitoring is not required at NCore sites until January 1, 2011, ADEQ has b een monitoring lead there since 2005.
