This inventory includes emissions of coarse particulate matter <10 µm in diameter (PM10), fine particulate matter < 2.5 µm (PM2.5), nitrogen oxides, sulfur oxides, and ammonia. Emissions are calculated for both Maricopa County and the PM10 nonattaiment area. Annual totals as well as typical daily emissions are provided for all source categories.

The purpose of the ambient air monitoring network is to sample air pollution in a variety of settings, assess the health and welfare effects, and assist in determining sources of air pollution. In general, six basic monitoring objectives and five measuring scales are used to determine the network design. Since it is physically and fiscally impossible to monitor the air in every location, representative samples must be obtained. These samples are determined by using the monitoring objectives and the spatial measurement scales. The network must be dynamic enough to maintain a current representative sample of the air quality. Air quality issues such as eight-hour ozone non-attainment boundaries and permits for new sources are diverse and controversial subjects for the citizens of Maricopa County. With its robust air monitoring network and mobile monitoring tools, the department strives to provide the most reliable and relevant air monitoring data to the public.

Arizona public school districts' dollars spent in the classroom. In November 2000, voters approved Proposition 301, which increased the State’s sales tax from 5 percent to 5.6 percent to provide additional money for educational programs. The enabling legislation for Proposition 301 requires the Auditor General to “. . . monitor school districts to determine the percentage of every dollar spent in the classroom by a school district.” This report presents our analysis of the percentage of dollars spent in the classroom for the most recently completed school year.

This Campaign Effectiveness Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2013-2014 Clean Air and Clean Stormwater Program Campaigns. This project analyzed and tracked the overall effectiveness of the Clean Air Program after 24 campaign sessions. For the second consecutive year, the survey also measured and tracked attitudes, knowledge, awareness, and behaviors related to stormwater management for the Clean Stormwater Program Campaign.

This Campaign Effectiveness Travel Behavioral Study, conducted for the Pima County Department of Environmental Quality, was designed to evaluate the specific effectiveness of the 2012-2013 Clean Air Campaign, as well as analyze the overall effectiveness of the air quality media campaign after 23 campaign sessions. New to the current study, the survey also measured baseline awareness/knowledge related to storm water and hazardous waste issues.

The Arizona Department of Transportation, the Arizona Game & Fish Department and the Arizona State Parks Board are required to conduct a study every three years on watercraft fuel consumption and recreational watercraft usage. The fuel consumption data is collected to determine the allocation of motor vehicle fuel tax to the State Lake Improvement Fund. The information on recreational watercraft usage patterns on Arizona’s lakes and rivers is necessary, in part, to determine the distribution of SLIF funds to applicants.

In fiscal year 2011, Chino Valley Unified School District’s student achievement was similar to peer district and state averages, and its operational efficiencies were mixed with some costs higher and some costs lower than peer districts’ averages. The District’s per-pupil administrative costs were slightly higher than peer districts’ because the District employed more administrative positions per pupil. The District’s plant operations, food service, and transportation programs operated reasonably efficiently, with cost measures such as cost per square foot, cost per meal, and cost per mile that were similar to or lower than peer districts’ averages. However, the District needs to improve controls over access to critical information systems and strengthen controls over its fuel purchase cards.

In fiscal year 2012, Duncan Unified School District’s student achievement was similar to peer districts’, and the District operated efficiently overall. Although the District’s administrative costs per pupil were slightly higher than the peer districts’ average, the District has taken steps to reduce its costs by reducing its number of administrative positions. The District’s plant operations, food service, and transportation programs were efficient with lower costs per square foot, per meal, and per mile, respectively, than peer districts’ averages. However, the District needs to improve its purchasing and computer controls. The District also needs to accurately determine, and report to the Arizona Department of Education, its ridership information to help ensure the District is properly funded and to allow it the ability to calculate and monitor transportation performance measures such as cost per rider and bus capacity utilization. Further, the District should ensure that its inmate worker documentation complies with statute.

In fiscal year 2012, Fowler Elementary School District’s student achievement was slightly higher than the peer districts’ averages, and the District operated efficiently. The District’s administrative cost per pupil was similar to the peer districts’ average, and it employed proper accounting and computer controls. The District’s plant operations costs per pupil and per square foot were lower than the peer districts’ averages primarily because of lower energy costs. Additionally, the District’s food service cost per meal was lower than the peer districts’ average, and the program was self-sufficient, in part, because the District paid the vendor that ran its program lower administrative and management fees than peer districts, on average. Further, the District’s transportation program was efficient, with lower costs per mile and per rider and efficient bus routes. However, the District did not accurately report its number of riders transported, which resulted in substantial overfunding for fiscal years 2011 through 2014.

In fiscal year 2012, Isaac Elementary School District’s student achievement was similar to peer district averages, and the District’s operational efficiencies were mixed, with much higher administrative and plant operations costs than peer districts’ averages but lower food service costs. Between fiscal years 2007 and 2012, the District decreased its classroom spending while it increased nonclassroom spending, primarily for administration and plant operations. At the end of fiscal year 2011, the District closed two schools to reduce costs, but its administrative and plant operations costs remained high, partly because of higher staffing levels. The District’s transportation program operated efficient bus routes but had much higher costs per mile and per rider than peer districts’, partly because it operated a smaller program but also because it offered more generous benefits. Finally, the District lacked adequate controls over user access to its computer network and systems.
