Subpart J of Part 51 specifies that Part 58 Subpart C 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 multi-pollutant monitoring stations (NCore) Photochemical Assessment Monitoring Stations (PAMS) Speciation Trends Network (STN) 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, wilderness areas). Class I monitoring sites are subject to specific siting and operational guidance developed by the IMPROVE Steering Committee AIRNow information sites Source-oriented monitoring sites operated independently by permittees (Industry) Meteorological sites. This Annual Monitoring Network Plan identifies the purpose(s) of each monitor and provides evidence that both the siting and the operation of each monitor meet the requirements in 40 CFR Part 58 appendices A, C, D, and E as follows: • Appendix A – Quality Assurance Requirements for SLAMS, SPMs, and PSD (Prevention of Significant Deterioration) Air Monitoring • Appendix C – Ambient Air Quality Monitoring Methodology • Appendix D – Network Design Criteria for Ambient Air Quality Monitoring • Appendix E – Probe and Monitoring Path Siting Criteria for Ambient Air Quality Monitoring Results of the annual network review and planning are used to determine how well the network is achieving its required air monitoring objectives, how well it meets data users’ needs, and how it should be modified (through termination of existing stations, relocation of stations, establishment of new stations, monitoring of additional parameters, and/or changes to the sampling schedule) in order to continue to meet its objectives and data needs. The network review and planning are performed for the purpose of improving the network and ensuring that it provides adequate, representative, and useful air quality data. 3 2.0 PROGRAM AND NETWORK DESCRIPTIONS Compliance Networks The compliance networks consist of stations operated for the purpose of demonstrating compliance with a NAAQS pollutant; compliance with CAA required monitoring such as PAMS, and conformance with special Federal grant programs the Agency accepted such as NATTS. Data collected at compliance sites are used to assess criteria pollutant concentrations, provide data used in modeling and SIP applications, track national trends, or monitor specific point-source emissions. The criteria pollutants are presently defined as sulfur dioxide (SO2), total particulate lead (Pb), suspended particulate matter (PM10 and PM2.5), ozone (O3), nitrogen dioxide (NO2), and carbon monoxide (CO). The criteria pollutants are measured with instruments meeting EPA certification as Federal Reference or Equivalent Methods. SIP and Maintenance Area Networks ADEQ maintains several air monitoring networks for the purpose of tracking compliance in areas that are currently not attaining a NAAQS or in an area where the NAAQS has been met and on-going demonstration of compliance is required. Monitoring requirements for these areas are described in their specific State Implementation Plans (SIPs). NCore NCore sites are required under 40CFR, Part 58, Appendix C. The plan for establishing required NCore multipollutant stations shall be submitted to the Administrator not later than July 1, 2009, and shall provide for all required stations to be operational by January 1, 2011. The sites are planned for large metropolitan areas and are generally required at a rate of one site per state. NCore is basically an extension of the current air monitoring networks, but with an opportunity to address new directions in air monitoring, and to begin filling measurement and technological gaps that have accumulated over the years. Emphasis is placed on a backbone of multi-pollutant sites, continuous monitoring methods, and important pollutants over and above the criteria pollutants, for example, ammonia, and reactive nitrogen compounds (NOy). When completed, NCore will meet a number of important needs: improved data flow and timely reporting to the public, NAAQS compliance determinations, supporting development of emissions strategies, assuring accountability for control programs, and supporting scientific and health-based studies. The ADEQ JLG Supersite in Phoenix is anticipated to be the Arizona NCore site. National Air Toxics Trend Sites (NATTS) The NATTS network was designed to document the concentration of certain air toxics on a national scale. ADEQ accepted Federal funding and responsibility for this program in 2003. Data from EPA’s national monitoring activities will establish an estimate of national average concentrations for these air toxics compounds, allow EPA to evaluate the need for new National Ambient Air Quality Standards (NAAQS), and establish associated limits. Data from sites in this trends network will be used to identify the probability that long-term changes or trends in ambient air concentrations are occurring. Using this information, EPA, states, and local agencies can estimate changes in the risks of human exposure. These changes can then be used to anticipate changes in environmental policy and to establish a regulatory stance. As part of the overall National Air Toxics Assessment (NATA) process, ambient air quality data are important to help assess the national toxics inventory and long-term hazardous air pollutant (HAP) trends. Photochemical Assessment Monitoring Stations (PAMS) Section 182(c)(1) of the 1990 Clean Air Act Amendments required the Administrator to promulgate rules for the enhanced monitoring of ozone, oxides of nitrogen (NOx) and volatile organic compounds (VOCs) to obtain more comprehensive and representative data on ozone air pollution. Immediately following the promulgation of those rules, the affected states were to begin actions necessary to adopt and implement a program to improve ambient monitoring activities and the monitoring of emissions of NOx and VOCs. Each state implementation plan (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 photochemical assessment monitoring stations (PAMS) as part of their SIP monitoring networks in ozone nonattainment areas 4 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 ozone NAAQS and the need for a more comprehensive air quality database for ozone and its precursors. PM2.5 Speciation Trends Network (STN) The STN was established to meet the regulatory requirements for monitoring PM2.5 to determine the chemical composition of these particles. There are approximately 54 STN sites across the nation, as well as additional SLAMS speciation sites. The purpose of the network is to determine, over a period of several years, trends in concentration levels of selected ions, metals, carbon species, and organic compounds in PM2.5. Locations are primarily in or near larger Metropolitan Statistical Areas (MSAs). ADEQ operates one STN speciation sampler at the JLG Supersite. Two IMPROVE samplers are also operated at the JLG Supersite for the purpose of providing precision information for the IMPROVE network and to make comparisons between the speciation results from both programs. Semi-continuous PM2.5 Speciation Network (PM2.5 grant) ADEQ is a participant in an EPA pilot study of semi-continuous speciation monitors being evaluated at five Speciation Trends Network (STN) sites in the United States. The pilot study began early in 2002 with newly established monitoring in Seattle, Washington; Phoenix, Arizona; Houston, Texas; Chicago, Illinois; and Indianapolis, Indiana. The goals of the pilot study are to assess the operational characteristics and performance of semi-continuous carbon, nitrate, and sulfate monitors for routine application at STN sites; to work with the pilot participants and the vendors to improve the measurement technologies used; and to evaluate the use of an automated data collection and processing system for real time display and reporting. ADEQ currently operates a Sunset Labs OC/EC carbon analyzer and 8400 Nitrate analyzer. Source Oriented Networks Historically, ADEQ has required several of the major point sources in the state to conduct ambient monitoring for criteria pollutants 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. Recently, however, SIP support has required the submittal of data to AQS. 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, aethalometers, 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 Clean Air Act Amendments. The evaluation which was performed by the U.S. Forest Service (USFS) and National Park Service (NPS) reviewed the wilderness areas of parks and national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated across the nation, 12 are located in Arizona. From the Class I Area designations, EPA initiated a nationally-operated monitoring network in 1987 called the 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. 5 AIRNOW Reporting ADEQ currently utilizes four urban nephelometers to approximate and report PM2.5 data to the AIRNOW Web site to provide near real-time data for public use. The PM2.5 value is calculated by applying a correlation developed between the nephelometer and filter-based measurements. The program is voluntary and was originally intended to fill gaps in the AIRNOW network until actual continuous methods were available. Meteorological Network ADEQ collects meteorological data at sites throughout the state to provide weather information for those air quality monitoring sites not located near official weather-observing equipment. 6 3.0 MONITORING NETWORK EVALUATION This section provides a description of the current air monitoring network and identifies monitors that are mandatory through the revised monitoring regulations, a SIP, a maintenance plan, or other grant requirement (such as NATTS) and also evaluates the status of the network in comparison to the revised monitoring rules. Recommendations are made regarding site possible additions as well as those that can be closed. Section 3.1 provides a brief discussion of monitors that were closed at the end of 2006 or will be closed in 2007. Section 3.1 also includes a description of new sites or monitors that will be implemented in 2007 or early 2008. The site closures and additions are also provided in Table 3.1-1. 3.1 Network Changes Closures NOx Monitors Alamo Lake (SPM) – NOx monitoring concluded after the 2006 season. ADEQ determined that an adequate NOx record was collected during the 2005 and 2006 ozone seasons. Ozone monitoring will continue in 2007. Tonto National Monument (SPM) – Trace level reactive NOx was discontinued after the 2006 ozone season. ADEQ has collected trace level NOx data at this site since 2000 and a determination was made that an adequate data record is in place. Ozone monitoring will continue in 2007. Yuma Game & Fish (SPM) – NOx monitoring will conclude at the close of the WASBAQS study in late April 2007. An adequate data record has been collected over the past 2 years. Ozone monitoring will continue in 2007. PM10 Monitors Hayden Jail (SPM) – Continuous PM10 monitoring will conclude in December 2007. The monitor was placed at the request of the EPA and EPA’s contractor. ADEQ has agreed to operate the site for an additional year. Safford (SLAMS) – PM10 filter-based sampling will be discontinued December 31, 2007. The Safford monitoring site is not required by EPA regulation. A lengthy data record (20 years) shows compliance with PM10 NAAQS. ADEQ has conducted analysis according to 40CFR 58.14(c)(1) and found that the monitor has less than a 10 percent chance of exceeding the NAAQS and is eligible for closure according to the regulation (the 90% Confidence Level is 91 µg/m3, which is less than 80% of the NAAQS, or 120µg/m3). The site is no longer necessary to demonstrate NAAQS compliance and resources could be applied in other locations. Sedona Post Office (SPM) – PM10 filter-based sampling will be discontinued December 31, 2007. The Sedona Post Office monitoring site is not required by EPA regulation. The Flagstaff monitor is adequate to represent the MSA and also is in a larger population setting with higher emissions. A lengthy data record shows compliance with NAAQS. The site is no longer necessary to demonstrate NAAQS compliance and resources could be applied in other locations. ADEQ is currently conducting continuous PM10 monitoring at Sedona Post Office with a nonreference method to investigate prescribed fire and wildfire impacts. The system can also provide near real-time information to the public. Show Low (SLAMS) – PM10 filter-based sampling will be discontinued December 31, 2007. The Show Low monitoring site is not required by EPA regulation. A lengthy data record shows compliance with NAAQS. The site is no longer necessary to demonstrate NAAQS compliance and resources could be applied in other locations. ADEQ has conducted analysis according to 40CFR 58.14(c)(1) and found that the monitor has less than a 10 percent chance of exceeding the NAAQS and is eligible for closure according to the regulation (the 90% Confidence Level is 58µg/m3, which is less than 80% of the 24-hour NAAQS, or 120µg/m3). In mid-2007 a continuous, non-reference method, PM10 monitor will be installed at the site to investigate prescribed fire and wildfire impacts. The system can also provide near real-time information to the public. 7 PM2.5 Monitors Payson Well Site (SLAMS) – PM2.5 measurement will be discontinued December 31, 2007. The site is not required by EPA regulations and an adequate record exists to demonstrate compliance with the NAAQS. ADEQ has conducted analysis according to 40CFR 58.14(c)(1) and found that the monitor has less than a 10 percent chance of exceeding the NAAQS and is eligible for closure according to the regulation (for the 24-Hour NAAQS, the 90% Confidence Level is 24µg/m3, which is less than 80% of the NAAQS, or 28µg/m3; for the annual NAAQS, the 90% Confidence Level is 10µg/m3, which is less than 80% of the NAAQS, or 12µg/m3). PM10 sampling will continue to support the current state implementation plan for the area (SIP). SO2 Monitors San Manuel (SLAMS) – ADEQ proposes to close the San Manuel SO2 monitoring site effective December 31, 2007. Federal regulations at 40 CFR 58.14 allows sites to be closed under specific circumstances. ADEQ believes that the closure of the San Manuel SO2 site meets these criteria. Specifically, the option under 40 CFR 58.14(c)(3) allows for discontinuation of a monitor within an attainment, nonattainment, or maintenance area, “…provided the monitor has not measured violations of the applicable NAAQS in the previous five years, and the approved SIP provides for a specific, reproducible approach to representing the air quality of the affected county in the absence of actual monitoring data.” This position is supported with the information provided below. Monitoring data for 2002 through 2006 indicate that maximum ambient concentrations were three percent or less of the NAAQS for the 3-hour standard; five percent or less of the NAAQS for the 24-hour standard; and less than seven percent of the NAAQS for the annual standard. Following the shutdown of the San Manuel ambient SO2 monitor, ADEQ will continue to demonstrate attainment and maintenance of the SO2 NAAQS through updates to the emissions inventory as described in Final Arizona State Implementation Plan Revision, San Manuel Sulfur Dioxide Nonattainment Area, March 2007 (SIP). Analyses contained in the SIP demonstrate that, although there were other sources of SO2 emissions, the San Manuel copper smelter, which permanently closed in 2005, was the primary emissions source in the nonattainment area and comprised more than 99.5 percent of total emissions while it was operating. The more than 99 percent emissions reduction due to the closure of the smelter corresponds to a greater than 92 percent reduction in 3-hour average and 24-hour average ambient SO2 concentrations. With the permanent closure of the San Manuel smelter, no major point sources exist in the nonattainment area. Sulfur dioxide emissions in 2017 are projected to be less than 0.5 percent of 1997 and 1998 total nonattainment area emissions, a period in which the San Manuel smelter was operating full time. Arizona does not anticipate any substantial increase in existing point source emissions between 2005 and 2017 for the nonattainment area. Should any growth occur due to construction of additional SO2 point sources, the ADEQ, Pinal County Air Quality Control District, and Pima County Department of Environmental Quality permit programs limit all emissions as part of construction of new point sources or upgrading of existing sources. ADEQ commits to re-establish an appropriate network before any major source of SO2 begins operations in the San Manuel planning area. PAMS Monitors South Phoenix – PAMS (VOC and Carbonyl) monitoring concluded at the close of the 2006 PAMS season. Refer to Section 6.0 of this document or the 2007 PAMS plan for a detailed description of the network. Maricopa County will continue to operate ozone at the site. Beginning July 2, 2007, ADEQ will begin regular toxics sampling at the South Phoenix site using canister samples analyzed using EPA Method TO-15. Sample collection frequency will be every 12th day. New Sites Flagstaff Area Ozone – According to the site assessment for ozone, conducted in Section 4.3, the addition of an ozone site is required in the Flagstaff MSA to meet the EPA minimum monitoring requirements. ADEQ will investigate the possibility of adding ozone monitoring in the Flagstaff MSA with the target of completion by April 1, 2008. Prescott Area Ozone - According to the MSA assessment for ozone, conducted in Section 4.3, the addition of an ozone site is required in the Prescott MSA to meet the EPA minimum monitoring requirements. ADEQ will 8 investigate the possibility of adding ozone monitoring in the Prescott MSA with the target of completion by April 1, 2008. Prescott Area PM2.5 – According to the MSA assessment for PM2.5, conducted as described in Section 4.3, the addition of a PM2.5 site is warranted in the Prescott MSA to evaluate pollutant concentrations in the MSA. Without historical PM2.5 data available for the MSA, ADEQ is unable to effectively evaluate the need for monitoring in the Prescott area. ADEQ will operate a Special Purpose PM2.5 sampler in the Prescott area during 2008 for a period of 24 months to evaluate concentrations there. Future grant funding levels for the PM2.5 program will dictate the feasibility of adding this monitor. Yuma Area PM2.5 – According to the MSA assessment for PM2.5, conducted in Section 4.3, the addition of a PM2.5 site is warranted in the Yuma MSA to evaluate pollutant concentrations in the MSA. Without historical data in the MSA, ADEQ is unable to effectively evaluate the EPA minimum monitoring requirements. ADEQ will operate a Special Purpose PM2.5 sampler in the Yuma area during 2008 for a period of 24 months to evaluate concentrations there. Future grant funding levels for the PM2.5 program will dictate the feasibility of adding this monitor. 9 Table 3.1-1 Monitors Closed in 2006-07 Site Name AQS ID Classificatio n Scale Objective Parameter(s) Reported Measured to AQS Reason for Monitor Transport NOX Yes Concurrent reading with ozone Alamo Lake 04-012-8000 SLAMS Regional Hayden Old Jail 04-007-1001 SPM Neighborhood Source Impact Continuous PM10 Yes, at end of study Support EPA study Payson - Well Site 04-007-0008 SLAMS Neighborhood Population PM2.5 Yes General population exposure Safford 04-009-0001 SLAMS Neighborhood Population PM10 Yes General population exposure Sedona – Post Office 04-005-1010 SPM Neighborhood Population PM10 Yes General population exposure San Manuel 04-021-2001 SLAMS Neighborhood Population SO2 Yes General population exposure Show Low 04-017-0007 SLAMS Neighborhood Population PM10 Yes General population exposure Tonto National Monument 04-007-0010 SLAMS Regional Downwind Concentration NOy No Ozone research and forecasting SLAMS Regional Downwind Concentration NOtl Yes Ozone research and forecasting SLAMS Neighborhood Max Conc.

The minimum monitoring requirements are based upon Metropolitan Statistical Areas (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. In the revised monitoring rule, EPA removed minimum requirements for carbon monoxide, sulfur dioxide, nitrogen oxide, and lead. Tables 4.1-1 through 4.1-3, shown below, list the minimum monitor requirements for PM2.5, PM10, and Ozone, respectively. Table 4.1-4 illustrates the Arizona MSAs and their respective populations as defined in the 2000 census. Arizona does not have any defined CSAs.

For SLAMS PM2.5 sites with both manual and continuous PM2.5 monitors operating, the monitoring agency may request approval from the EPA Regional Administrator for a reduction to 1-in-6 day PM2.5 sampling at SLAMS stations or for seasonal sampling. The EPA Regional Administrator may grant sampling frequency reductions after consideration of factors including, but not limited to, the historical PM2.5 data quality assessments, the location of current PM2.5 design value sites, and their regulatory data needs. Sites that have design values that are within plus or minus 10 percent of the NAAQS (±10% of 35µg/m3 is 31.5-38.5) and sites where the 24-hour values exceed the NAAQS for a period of 3 years are required to maintain at least a 1-in-3 day sampling frequency. Sites that have a design value within plus or minus 5 percent of the daily PM2.5 NAAQS (±5% of 35µg/m3 is 33.25-36.75) must have an FRM or FEM operating on a daily schedule. ADEQ will not alter any PM2.5 sample frequencies until resolution of the network configuration is made. Table 4.2-1 PM2.5 Sampling Frequencies Site Name Douglas Red Cross Flagstaff Middle School Payson Well Site JLG Supersite Nogales Post Office 3-Year Average of 98th percentile 20032005 16.7 Current Sample Frequency 1 in 6 Historical Sample Frequency 1 in 6 16.8 1 in 6 1 in 6 1 in 3 22.4 26.7 31.0 1 in 6 1 in 3 1 in 6 1999-2001 1 in 3 1999-2000 Daily 1 in 6 1 in 3 1 in 3 1 in 3 New Required Frequency 1 in 3 PM10 The monitoring rule at §58.12 (e) states that for PM10 sites, the minimum monitoring schedule for the site in the area of expected maximum concentration shall be based on the relative level of that monitoring site concentration with respect to the 24-hour standard. ADEQ does not currently operate any PM10 monitoring sites with a stated objective of recording maximum concentration. The PM10 monitoring conducted is generally neighborhood scale with the intent of documenting general population exposure. Therefore, no changes to sample collection frequency are needed. 4.3 ADEQ Minimum Network Status 40 CFR 58.13(b) allows for new network minimum monitoring requirements to be met by January 1, 2008. The sections below address the minimum requirements for MSAs under the jurisdiction of ADEQ: Flagstaff MSA, Yuma MSA, and Prescott MSA. Monitoring in the Maricopa-Pinal MSA and Tucson MSA will be addressed by Maricopa, Pinal, and Pima counties in their respective monitoring plans. PM2.5 According to Tables 4.1-1 and 4.1-4, the minimum PM2.5 monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, and Flagstaff MSAs. Each MSA has a population in the 50K-500K category. Table 4.3-1 describes concentrations as a PM2.5 design value for current and historical sites operated by ADEQ. The following section reviews current monitoring locations and evaluates potential needs under the monitoring rules. 12 Table 4.3-1 PM2.5 Design Values PM2.5 Concentrations (µg/m3) Most Recent 3-Year Design Value for 24-Hour Averages (85% NAAQS is 29.75) MSA Represented Value Site None – Santa Cruz County Nogales (2003-2005) 31.0 Phoenix JLG Supersite (2003Phoenix MSA 2005) 26.7 Yuma MSA Yuma (1998-2000) 25.6 None – Gila County Payson (2003-2005) 22.4 Flagstaff Middle School (2003Flagstaff MSA 2005) 16.8 None – Cochise County Douglas (2003-2005) 16.7 Prescott MSA Clarkdale-School (1998-2000) 6.6 ADEQ operates a federal reference method filter-based PM2.5 sampler in the Flagstaff MSA but not in the Yuma or Prescott MSAs. Yuma MSA (Yuma County) – Historical dichotomous filter data can be used to estimate a design value for the Yuma MSA. ADEQ operated a dichotomous PM sampler at the Yuma County Courthouse for a number of years prior to replacing the samplers with newer equipment in 2001 which measured only PM10. The period evaluated is 1998-2000 and indicates a design value of 25.6µg/m3, which is less than 85% of the NAAQS. Because the data were collected 7 years ago and the nature of the area may have changed, ADEQ plans to operate a Special Purpose PM2.5 monitor at the Yuma Courthouse site starting in January 2008 to evaluate PM2.5 concentrations. Sampling will be conducted for a period of approximately 24 months. Prescott MSA (Yavapai County) - Historical dichotomous filter data can be used to estimate a design value for the Prescott MSA. ADEQ operated a dichotomous sampler at the Clarkdale School until 2000 when the site was permanently closed. The period evaluated 1998-2000 and indicates that the design value of 6.6µg/m3 which is significantly less than 85% of the NAAQS. Because the data were collected 7 years ago and the Clarkdale site may not adequately represent the Prescott MSA, ADEQ plans to operate a Special Purpose PM2.5 sampler at the Prescott Valley site starting in January 2008 to evaluate PM2.5 concentrations. Sampling will be conducted for a period of approximately 24 months. In addition to the sites described above, ADEQ currently operates a PM2.5 sampler at and the mountain community of Payson. This monitoring activity was described in detail in the 1999 Arizona PM monitoring plan submitted to EPA Region IX (Particulate Matter PM2.5 & PM10 National Ambient Air Quality Standards NAAQS Monitoring Networks: The 1999 Arizona Plan Description). The plan described the purpose and necessity of this site based upon historical concentrations, meteorology, and knowledge of emission characteristics of the areas. As described in Section 3.1, ADEQ will no longer operate the Payson site because historic concentrations provide ample record of compliance with the NAAQS. Additionally, the concentrations are less than 85% of the NAAQS and they are no longer required under EPA regulations. PM10 According to Tables 4.1-2 and 4.1-4, the minimum PM10 monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, and Flagstaff MSAs. The Prescott, Yuma, and Flagstaff MSAs fall under the 100K-250K population category for PM10 monitoring. The following section reviews current monitoring locations and evaluates potential needs under the monitoring regulations. ADEQ currently operates one or more reference method filter-based PM10 samplers in each MSA. Prescott MSA (Yavapai County) - ADEQ currently operates a reference method PM10 sampler at Prescott Valley. The maximum value recorded over the last three years of operation is 56 µg/m3, approximately 37% of the 13 NAAQS. Therefore, the site is considered a low category as described in Table 4.1-2 and the single monitoring site at Prescott Valley is adequate to meet the rule requirement. Yuma MSA (Yuma County) – ADEQ Currently operates a reference method PM10 sampler at the Yuma Juvenile Center (Courthouse). The site is also required under the current SIP Maintenance Plan described in additional detail in section 4.3 of this document. Maximum concentrations recorded over the past three years are less than 80% of the NAAQS. Therefore, the area is considered to be in the low category and the single monitoring site in Yuma is adequate to meet the rule requirement. Flagstaff MSA (Coconino County) – ADEQ currently operates two reference method PM10 samplers in the Flagstaff MSA, one in Flagstaff and one in Sedona. Both sites are less than 80% of the PM10 NAAQS. For the Flagstaff and Sedona monitors, the maximum values recorded over the last three years of operation are 43 µg/m3 (29% of the NAAQS) and 36 µg/m3 (24% of the NAAQS), respectively. Therefore, the sites are considered low category as described in Table 4.1-2, and a single monitoring site in the MSA is adequate to meet the rule requirement. ADEQ will continue operation of the Flagstaff PM10 site for the remainder of 2007. Ozone According to Tables 4.1-3 and 4.1-4, the minimum ozone monitoring network for Arizona, excluding Maricopa, Pinal and Pima Counties, must consider sites in the Prescott, Yuma, and Flagstaff MSAs. The Prescott, Yuma, and Flagstaff MSAs are in the 50K-350K population category. ADEQ currently operates an ozone analyzer in the Yuma MSA. Ozone monitoring is currently not conducted by ADEQ in the Prescott or Flagstaff MSAs. The section below describes historical monitoring by ADEQ and current monitoring by other entities in these MSAs. Yuma MSA (Yuma County) - ADEQ currently operates one ozone monitor at Yuma Game and Fish. The 20042006 design value for the Yuma Game and Fish site is 74 ppb, or approximately 92.5% of the 8-hour ozone NAAQS. Based upon this value, the single site in Yuma is adequate to meet the minimum monitoring requirements described in Table 4.1-3. Prescott MSA (Yavapai County) – Historically, ADEQ operated an ozone monitor at Hillside. Hillside was operated through the 2005 season with a 2003-2005 design value of 72 ppb, which exceeds 85% of the 8-hour NAAQS. The site represented upwind transport of ozone into the central Arizona and did not, by design, represent the Yavapai County population. Because an adequate data record does not exist to represent the MSA, ADEQ will add an ozone site in the Prescott area starting in the 2008 ozone season. Flagstaff MSA (Coconino County) – ADEQ has not operated an ozone site in Coconino County. The National Park Service (NPS) has been operating an ozone site at the South Rim of the Grand Canyon since approximately 1990. The trend has generally been an increase in ozone concentrations over time. The latest data available indicate a 3 year average of the 4th high 8-hour concentration of 72 ppb in 2003-2005. This is above the 85% measure described in the Ozone Monitoring (SLAMS) table above and would indicate the necessity of an ozone site in the Flagstaff MSA. Because an adequate data record does not exist to represent the population center of the MSA, ADEQ will add an ozone site in the Flagstaff area starting in the 2008 ozone season. Ozone Season In accordance with 40CFR Part 58, Appendix D, Paragraph 4.1(i), the Arizona Department of Environmental Quality is requesting a modification to the ozone season defined in regulation. The specified season defined in Table D-3 of Appendix D is January through December for the State of Arizona. ADEQ believes the appropriate ozone season for sites under our operation to be April 1 through October 31 each year. We base this upon the attached data summary from two sites operated by ADEQ, which illustrates that ozone concentrations have not historically exceeded 70 ppb during the period from October through March. See Illustration 4.3-1 below. Additionally, a 1998 EPA guidance document entitled, “Guideline for Selecting and Modifying the Ozone Monitoring Season Based on an 8-Hour Ozone Standard” supports a shorter ozone season for Arizona based upon data collected from 1990 through 1995. 14 The modified seasonal schedule would be applied to the following sites: Alamo Lake, Queen Valley, Yuma Game and Fish, and Tonto National Monument. The JLG Supersite would continue to operate on a January to December schedule. Upon approval of this modification, ADEQ will make appropriate corrections to the seasonal definition in the AQS database and annual monitoring plan.

Volatile organic compound (VOC) and carbonyl samplers collect ambient air in hydrocarbon (HC) canisters and in cartridges containing silica substrate impregnated with acidified 2, 4-Dinitrophenylhydrazine (DNPH), respectively, which are routinely analyzed for chemical constituents. In 2007 ADEQ will add an automated GC/MS monitoring system for collection and analysis of PAMS data at the Phoenix JLG Supersite. The instrument will be operated by an outside contractor. ADEQ also operates ozone (O3), oxides of nitrogen (NOx), and surface meteorological monitoring equipment at most sites. At two of the monitoring sites (Phoenix JLG Supersite and Queen Valley), additional ozone-related monitoring equipment (trace level oxides of nitrogen - NOTL, total reactive oxides of nitrogen - NOy) is operated to provide more complete characterization of the atmospheric chemistry in the MSA. ADEQ will discontinue collection of PAMS VOC and carbonyl samples at the South Phoenix site and implement toxics sampling using TO-15 collected on an every 12th day schedule. Accordingly, the site will be removed from the PAMS site list. Maricopa County Air Quality Department (MCAQD) will continue operation of ozone and surface meteorological monitoring equipment at the South Phoenix site. Type 2 - JLG Supersite: 17th Ave. & Campbell, Phoenix. The JLG Supersite was designated a PAMS site in 1999. Monitoring instrumentation at the site includes continuous GC/MS, multi-canister samplers for VOCs, multiport carbonyl samplers, ozone, oxides of nitrogen, total reactive oxides of nitrogen, wind speed and wind direction, temperature, and relative humidity. Trace level CO will be added to the site for the 2007 season if equipment can be obtained by June 1st. 15 Table 4.3-2 JLG Supersite PAMS Instrumentation Parameter Dates Method VOC 6/1/07 – 8/31/07 Continuous GC Carbonyl 6/1/07 – 8/31/07 Multi-port sampler Ozone Oxides of Nitrogen Reactive Oxides of Nitrogen Meteorology 1/1/07-12/31/07 4/1/07 – 10/31/07 4/1/07 – 10/31/07 Continuous Ozone Continuous NOx Continuous NOy 1/1/07-12/31/07 Wind Seed/Direction, Temperature, RH Duration Hourly average Every 6th day, 24Hr, 3 each 3hr sample (0500-0800, 0800-1100, 1100-1400) Hourly average Hourly average Hourly average Hourly average Type 3 - Queen Valley Site: 50 N. Queen Anne Drive, Queen Valley. Queen Valley was designated a PAMS site in 2001. The site is located near the southeastern edge of the photochemical modeling grid domain. Pollutants collected at the site include VOCs, ozone, and total reactive oxides of nitrogen. Carbonyl samples are not required at Type 3 sites.

ADEQ activities with respect to these networks have been limited to regular performance audits and review of ambient data. Recently, ADEQ has begun to submit a portion of these data to the EPA AQS database to support SIP compliance. Sources are required to review these data and submit quality assurance documents to ADEQ with the data. Table 4.5-1 describes the current source operated network. This monitoring plan does not intend to implement changes to these networks. The mechanism to alter these networks is through the permitting process in consultation with ADEQ's Permits and Planning Sections.

The rule requires that the annual monitoring network plan must document how States and local agencies provide for the review of changes to a PM2.5 monitoring network that impact the location of a violating PM2.5 monitor or the creation/change to a community monitoring zone, including a description of the proposed use of spatial averaging for purposes of making comparisons to the annual PM2.5 NAAQS as set forth in appendix N to part 50 of this chapter. The affected State or local agency must document the process for obtaining public comment and include any comments received through the public notification process within their submitted plan. 18 ADEQ does not intend to establish community monitoring zones as described in the rule or utilize spatial averaging for comparison to the PM2.5 NAAQS. To address the public comment process required prior to relocation of a violating monitor, 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. 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 has a Quality Management Plan in place for the agency that was completed in August 2005. Air Assessment submitted a Quality Assurance Program Plan to EPA Region 9 in November 2001. A Quality Assurance Project Plan (QAPP) was prepared for the PM2.5 program when it began in 1999. Updates to the QAPP were submitted to Region 9 in August 2006. ADEQ plans to combine particulate matter and gases into a QA Program Plan in 2007. A Toxics/PAMS QAPP was submitted in April 2006 and is currently being revised per comments from EPA Region 9. A QAPP for the gas monitoring program is scheduled to be completed in 2007. ADEQ uses the QAPPs prepared for EPA for the IMPROVE and STN programs. All instrument SOPs have been completed and submitted to EPA Region 9. Along with but separate from the Air Monitoring Unit, Air Assessment has a Quality Assurance (QA) Team of two staff members who reside in the Data Management & Quality Assurance Unit. The QA Team coordinates the preparation of the QAPP documents and conducts performance audits and Technical Systems Audits (TSAs). As part of the quality system, the Assessment QA Team has conducted audits of the ADEQ filter laboratory. Beginning in 2007, the Team will conduct Technical Systems Audits (TSAs) of the Southern Regional Office (SRO) and Northern Regional Office (NRO) staff who act as operators for the Monitoring Unit. The filter laboratory audit will be expanded to a Technical Systems Audit. SOPs for the TSAs are being prepared for conducting these audits. Beginning in 2007, 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. Beginning in 2007, the ADEQ QA Team will be conducting audits of IMPROVE samplers for the EPA. Twelve samplers in Arizona's network will be audited. EPA Region 9 conducted a Technical Systems Audit of the Air Assessment Monitoring Program in December 2004. 19 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 ozone standard used by the Team are checked twice per year. All monitors (PMs, gases, meteorology) in the Western Arizona Sonora Border Air Quality Study (WASBAQS) were audited quarterly. ADEQ is the primary quality assurance organization for the monitors it operates. 5.3 Measurement Quality Checks – Precision Measurements 5.3.1 Particulate Monitors – Manual Methods – PM10 ADEQ operates two types of PM10 samplers with different methods: dichots and Partisols. The dichots are located at the two Mexico locations. Because the dichot samplers in Mexico are not considered part of the state compliance network, precision data are not collected for this method. PM10 concentrations from the dichot samplers are reported to AQS designated as monitor type 'Other'. Data are reported to AQS in standard (81102) and local conditions (85101). The Partisol samplers are located at 16 sites. Concentration data from all 16 sites are reported to AQS in standard and local conditions. 13 of the sites are designated as SLAMS; 3 sites are designated as SPM. Section 3.3.1 of CFR Part 58 Appendix A indicates that 15% of the sites must be collocated. The collocated monitors must be within 4 meters of each other and at least 1 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 POC 2. Beginning in 2007, collocated samples will be collected every 12th day. Flow rate verification will be checked monthly by Monitoring Unit staff. Table 5.3-1 PM10 Precision Monitoring by Method Sampling Method Dichot Partisol Total Number of Sites 2 (Mexico) 16 Number of Precision Sites 0 2 (Paul Spur & Yuma Courthouse) In 2007, ADEQ will continue to report PM10 concentrations to AQS for 3 monitors at 2 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 Phelps Dodge Corporation as a permit requirement. Phelps Dodge supplies flow check and audit reports to verify adherence to quality assurance procedures. 5.3.2 Particulate Monitors – Manual Methods – PM2.5 The PM2.5 network must include collocated sampling at 15 percent of the monitoring sites operated by the reporting agency. If the area has less than 4 sampling sites at least one must have a precision measurement. The total number of sites shown in Table 5.3-2 includes all PM2.5 samplers in the ADEQ network (this excludes sites operated by County and Tribal agencies). Table 5.3-2 PM2.5 - Precision Monitoring Sampling Method FRM (R&P partisols) Total Number of Sites1 5 20 Number of Precision Sites 1 (Nogales Post Office) 1. Excludes sites operated by Tribal Programs, Maricopa County, Pima County, and Pinal County. All five ADEQ sites are designated as SLAMS. Concentrations from all samplers are reported to AQS. All concentrations from the collocated monitor at Nogales are reported as POC 2. Collocated samples will to be collected every 6th day to ensure an adequate number of precision measurements. Flow rate verification will be checked monthly by Monitoring Unit staff. 5.3.3 Gas Monitors – SO2, O3, CO, NO2 Biweekly 1-point checks are performed by the monitoring staff for all gas monitors. These measurements are reported to the AQS. 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. 5.4 Measurement Quality Checks – Accuracy Measurements 5.4.1 Particulate Monitors – Manual Methods Beginning in 2007, the QA Team will conduct semi-annual flow rate audits on ADEQ PM10 and PM2.5 monitors. All accuracy measurements are reported to the AQS. 5.4.2 Gas Monitors – SO2, O3, CO, NO2 The QA Team conducts annual audits of all gas monitors. These are multi point performance audits. The audit measurements are reported to the AQS. 5.4.3 Meteorological Equipment Meteorological equipment are 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 AQS P/A Reporting Organization Summary report along with the Data Completeness Report to Region 9 in the annual Certification Letter. 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 gas biweekly checks are submitted quarterly as precision records. Audit information for both PM monitors and gas monitors are submitted quarterly. In 2007, the QA Team plans to develop 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. 5.6.1 Monitoring Objectives and Spatial Scales As stated in Appendix D of CFR 40 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. 21 • • Support compliance with ambient air quality standards. Support air pollution research and strategy development. To meet these objectives, the design of ambient air monitoring networks must consider the physical and chemical behaviors of the individual pollutants - including properties such as transport and dispersion. The locations of a network’s monitoring stations are selected to achieve one or more of the six basic objectives specified in CFR Part 58 Appendix D: 1. 2. 3. 4. 5. 6. Determine the highest concentrations expected in the area covered by the network. Measure representative concentrations in areas of high population density. Determine the impact of significant sources or source categories on air quality. Determine general background concentration levels. Measure regional pollution transport among populated areas. In support of secondary standards, to determine the welfare-related impacts in more rural and remote areas. Appendix D of 40 CFR Part 58 provides guidance concerning spatial scales of air parcels in which the pollutant concentration is reasonably similar. Monitoring stations are sited in one of the following scales of representativeness: microscale, middle scale, neighborhood scale, urban scale, or regional scale (see Table 5.6.11). 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 ozone levels downwind of a major metropolitan area. Table 5.6.1-1 Scale of Representativeness Scale of Representativeness Micro Middle Neighborhood Urban Regional National and Global Dimension several meters up to 100 meters 100 meters up to 0.5 kilometers 0.5 kilometers up to 4 kilometers 4 kilometers up to 50 kilometers rural areas or cities of homogeneous geography; can extend from tens to hundreds of kilometers thousands of kilometers The typical relationship between the monitoring objectives and spatial scale is summarized in Table 5.6.1-2. Appendix D of 40 CFR Part 58 provides additional detail concerning spatial scales for specific pollutants. Table 5.6.1-2 Monitoring Objectives Monitoring Objective Appropriate Siting Scales Highest/Maximum Concentration Population Source Impact General/Background Regional Transport Plant and Animal Welfare Impacts Micro, Middle, Neighborhood (sometimes urban) Neighborhood, Urban Micro, Middle, Neighborhood Neighborhood, Urban, Regional Urban/Regional Urban/Regional 5.6.2 General Monitoring Requirements 22 NCore Multipollutant Site – It is anticipated that the ADEQ JLG Supersite will be designated as an urban NCore site in the timeframe specified in the revised CFR 40. The scale of the sites is neighborhood, which complies with the recommendations in Part 58. Continuous monitoring methods will be employed where available. The data will be reported (AQS) and made available for air quality trends analyses, model evaluation, and NAAQS compliance. SLAMS – Although Part 58 states that SLAMS sites, other than NCore, are intended to address specific air quality management interests and are frequently single-pollutant measurement sites, many of ADEQ’s SLAMS sites are multipollutant for several reasons including the size of ADEQ’s territory and the economies achieved when such sites meet multiple pollutant-objective 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 the three Metropolitan Statistical Areas under ADEQ jurisdiction: Flagstaff, Prescott, and Yuma. The following sections include more general pollutant-specific design criteria. • Ozone – A greater number of sites than the specified minimum could be required to support public data reporting, air quality mapping, compliance and ozone-related research. This is particularly true of the Phoenix-Mesa-Scottsdale MSA that includes Maricopa and Pinal Counties but not of the Flagstaff, Prescott, or Yuma MSAs. Factors considered were the MSAs geographic sizes, population densities, meteorology, terrain, air transport, and the presence of ozone precursors. Section 3.2 provides background information on the current and historical ozone monitoring sites. • Carbon Monoxide – There are no minimum requirements for the number of CO monitoring stations but continued operation of existing sites is required – the JLG Supersite, in this case. In addition, where SLAMS (and, presumably NCore) CO monitoring is ongoing, at least one site must be a maximum concentration site. At present, the CO monitoring objective at the Phoenix JLG Supersite is population but other sites in the Phoenix MSA combine to meet the requirement. • Nitrogen Dioxide – There are no minimum requirements for NO2 but existing sites must continue to monitor unless authorized by the Regional Administrator to be discontinued. As with continued CO monitoring, continued NO2 monitoring implies that at least one NO2 monitoring site must be a maximum concentration site. The Phoenix JLG Supersite objective for NO2 monitoring is population but other sites in the Phoenix MSA combine to meet the requirement. • Sulfur Dioxide - There are no minimum requirements for SO2 but existing sites must continue to monitor unless authorized by the Regional Administrator to be discontinued. ADEQ monitors SO2 emissions at the Phoenix Supersite and at several mining sites. • Lead – No lead monitoring sites are required and no monitoring is being performed. • Particulate Matter (PM10) – Refer to section 4.3 ADEQ Minimum Network Status. • Fine Particulate Matter (PM2.5) – Refer to section 4.3 ADEQ Minimum Network Status. • Coarse Particulate Matter (PM10-PM2.5) – The ADEQ NCore site will meet requirements. 23 6.0 PROPOSED 2007-2008 COMPLIANCE MONITORING NETWORK Table 6.0-1 lists the air quality monitoring sites to be operated by ADEQ in 2007 and 2008.

The evaluation which was performed by the U.S. Forest Service (USFS) and National Park Service (NPS) reviewed the wilderness areas of parks and national forests which were designated as wilderness before 1977, were more than 6,000 acres in size, and have visual air quality as an important resource for visitors. Of the 156 Class I Areas designated across the nation, 12 are located in Arizona. From the Class I Area designations, EPA initiated a nationally-operated monitoring network in 1987 called the Interagency Monitoring of PROtected Visual Environments (IMPROVE) program. The purpose of the 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. 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.

There are no established federal or state standards for acceptable levels of urban haze. ADEQ began studying the nature and causes of urban hazes by conducting a study in the winter of 1989-90 in Phoenix and the winter of 1992-93 in Tucson. These studies recommended long-term, year-round monitoring of visibility. In 1993, ADEQ began deploying visibility monitoring equipment in Phoenix and Tucson. These visibility monitoring data are needed to provide policymakers and the public with information, track shortand long-term trends, assess source contributions to urban haze and better evaluate the effectiveness of air pollution control strategies. Equipment used to evaluate urban visibility includes transmissometers, nephelometers, aethalometers, particulate monitors, and digital camera systems. The Phoenix urban haze network includes two transmissometers (located in Phoenix and Mesa) for measuring light extinction along a fixed path length of about three to five kilometers, four nephelometers for measuring light scattering, five digital camera systems to record visual characteristics of the urban area, and particulate filters for quantifying and characterizing particulate matter. The Tucson urban haze network includes one transmissometer for measuring light extinction along a fixed path length of about three to five kilometers, three nephelometers for measuring light scattering, and a digital camera system operated by Pima County to record visual characteristics of the urban area. The sites are described in Table 7.2-1. 27 Table 7.2-1 Arizona Urban Haze Networks Site Name Parameter(s) Measured Phoenix Network ADEQ Building High Resolution Digital Camera Dysart Light Scattering (Bscat) Estrella Light Scattering (Bscat) Estrella Mountain Community College 2 High Resolution Digital Cameras Mesa Transmissometer Transmissometer (Bext), High Resolution Digital (Mesa City Building to Banner Medical Center) Camera Phoenix - JLG Supersite Light Scattering (Bscat), Aethalometer (Babs), 2 IMPROVE Phoenix - North Mountain Summit High Resolution Digital Camera Phoenix-Transmissometer Transmissometer (Bext) (Baptist Hospital to Sunshine Hotel) Phoenix - Vehicle Emissions Laboratory Light Scattering (Bscat) Tucson network Tucson - Children’s Park Light Scattering (Bscat) Tucson – Craycroft Light Scattering (Bscat) Tucson Transmissometer Transmissometer (Bext) Tucson – U of A Central Light Scattering (Bscat), Aethalometer (Babs) 7.3 Meteorology Network ADEQ collects meteorological data to provide weather information for the monitoring sites not located near official weather stations. Much of the equipment is located at visibility monitoring sites. Two locations collect data used to meet PAMS meteorological requirements. All meteorological data (with the exception of profiler and sodar measurements) receive two levels of quality assurance checks. The equipment is audited once per year.

The site includes wind speed, wind direction, ambient temperature and relative humidity. The site is intended to represent meteorological conditions on the Mesa above the Colorado River basin and is part of the meteorological network for WASBAQS. The immediate area surrounding the site is generally citrus groves and open, grassy fields. The U of A Extension office is located to the north. Temperature and relative humidity sensors are 2.2 meters above a soil covered surface. A group of several tall trees (approx 10 meters) is located approximately 35 meters west of the wind tower. EPA Meteorological guidance (Meteorological Monitoring Guidance for Regulatory Modeling Applications. EPA-454/R-99-005, EPA, 2000), suggests that wind sensors be located at a distance at least 10 times the height of nearby obstructions. This would require the wind system to be 100 meters from the nearly trees (10m X 10). Considering the number of trees and other structures on the Mesa, siting an instrument to these specifications would be nearly impossible. Recommendation is to operate the site and consider potential effects of trees when analyzing data.
