This document is an attainment demonstration, maintenance plan, and formal request to the United States Environmental Agency to redesignate the Miami, Arizona area, a nonattainnlent area for sulfur dioxide (SO,), to attainment for the health-based 24-hour average and annual average SO, National Ambient Air Quality Standards. It summarizes the progress ofthe area in attaining the SO, standards, demonstrates that all Clean Air Act requirements for attainment have been adopted, and includes a maintenance plan to assure continued attainment after redesignation. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

This document includes an attainment demonstration and formal request to the United States Environmental Protection Agency to redesignate the Hayden, Arizona Sulfur Dioxide (SO2) Nonattainment Area to attainment for the health-based 24-hour average and annual average SO2 National Ambient Air Quality Standards. It summarizes the progress of the area in attaining the SO2 standards, demonstrates that all Clean Air Act (CAA) requirements for attainment have been adopted, and includes a maintenance plan to assure continued attainment after redesignation. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

This document consists of the attainment demonstration, maintenance plan, and redesignation to attainment request for the Douglas Sulfur Dioxide (SO2) Nonattainment Area. The purpose of this document is to demonstrate how the State of Arizona has met the National Ambient Air Quality Standards for SO2 and intends to maintain compliance with the NAAQS in the Douglas area. Air quality standards are divided into two types: primary standards based on health effects and secondary standards based on environmental effects such as damage to property, plants, visibility, etc. Both standards are established by EPA for criteria air pollutants such as sulfur dioxide.

The Clean Air Act states that an area can be redesignated to attainment if specific conditions are met. This document demonstrates that all CAA requirements for attainment have been met, summarizes the progress of the area in attaining the PM10 standard, demonstrates that the Bullhead City area qualifies for EPA’s Clean Data Policy and Limited Maintenance Plan option, and includes a maintenance plan to assure continued attainment for ten years after the redesignation. This document includes a formal request to the U.S. Environmental Protection Agency to redesignate the Bullhead City, Arizona PM10 nonattainment area to attainment for the health-based 24-hour average and annual average PM10 National Ambient Air Quality Standard.

In addition, this document includes a formal request to revise the nonattainment area boundary, as currently defined in 40 CFR 81.303, to exclude three townships (108 square miles) in the east and south of the nonattainment area. The rationale for eliminating the three townships is that the land contains undisturbed desert terrain. The majority of the three townships is federal land managed by the Bureau of Land Management and state land managed by the Arizona State Land Department. Analyses included in this document show that ambient air quality measurements have remained below the NAAQS for PM10, and both the 24-hour average design value and annual average PM10 design value are below EPA’s LMP allowable limits. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

This document consists of the attainment demonstration, maintenance plan, and redesignation to attainment request for the Ajo Sulfur Dioxide (SO2) nonattainment area. The purpose of this document is to demonstrate how the area has met the National Ambient Air Quality Standards for SO2 and intends to maintain compliance with the NAAQS. Air quality standards are divided into two types: primary standards based on health effects and secondary standards based on environmental effects such as damage to property, plants, visibility, etc. Both standards are established by Environmental Protection Agency for criteria air pollutants such as sulfur dioxide.

In fiscal year 2011, Paradise Valley Unified School District’s student achievement was similar to peer districts’ and it operated efficiently overall. The District’s per pupil administrative costs were lower than peer districts’, and its food service and transportation programs operated efficiently. The District’s plant operations cost per square foot was lower than peer districts’. However, the District did not gain the full benefit of potential savings from this lower cost per square foot because it maintained a large amount of excess building space. The District should continue to review options to address its excess building capacity. Additionally, the District’s solar power system contracts are unlikely to meet expectations for cost savings, and although the District has taken action to recover estimated financial losses, it should continue to monitor its solar power production and electricity usage. The District also needs to strengthen controls over its computer systems.

In fiscal year 2012, Winslow Unified School District’s student achievement was similar to peer districts’ averages, but its cost-efficiency in noninstructional areas was mixed. The District’s per pupil administrative costs were much higher than peer districts’, on average, primarily because it employed more administrative positions. The District’s plant costs were higher primarily because it maintained a large amount of excess school building space, which was likely not needed because most of the District’s schools operated far below their designed capacities. The District’s food service program operated with slightly higher costs that may have been a result of it not sufficiently overseeing the vendor operating the program. The District’s transportation program operated in a reasonably efficient manner, despite having higher costs per pupil, but the District needs to strengthen controls over fuel purchases.

In fiscal year 2013, Safford USD's student achievement was similar to peer districts', and the District operated efficiently overall with most costs lower than, or similar to, the peer districts' averages. The District's administrative cost per pupil was similar to the peer districts' average, and its plant operations and food service program operated efficiently. Further, despite a higher cost per rider, the District's transportation program was reasonably efficient. However, the District should strengthen controls over its computer network and systems.

In fiscal year 2012, Santa Cruz Valley USD's student achievement was similar to peer districts', and its operations were reasonably efficient overall despite having some higher costs than peer districts', on average. However, the District needs to improve its computer controls, pay its credit cards in full to avoid interest charges, and accurately report its costs.

In fiscal year 2012, Tolleson ESD's student achievement was similar to peer districts', and its operational efficiencies were mixed, with some costs higher and some costs lower than peer districts', on average. Specifically, the District's plant operations and food service program operated efficiently, but its administration and transportation program operated less efficiently with higher costs than peer districts' averages.
