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 Committee selected the following environmental goal: A goal with the purpose of showing continued progress through 2018 by; 1) improving visibility to move days now in the poor/very poor categories up to the fair category, and 2) moving days classified as fair to the good/excellent categories. A progress
assessment will be conducted every 5 years through 2018. The members concluded that this option provides a clear, long term method to track visibility trends in the Phoenix metropolitan area. Additionally, the Committee reached general agreement that the index should not be used to affect short term actions because other programs, such as the High Pollution Advisory Program, are currently in place.

In fiscal year 2012, Laveen Elementary School District’s student achievement was similar to peer districts’ averages, and the District operated efficiently overall with lower costs per pupil than peer districts’, on average, in all operational areas. Despite operating efficiently, Laveen ESD spent 21 percent, or $751, less per pupil in the classroom than peer districts, on average, because it received less funding primarily because it had a lower poverty rate and fewer special needs students. In fact, the District had nearly the lowest overall per pupil spending amount in the State. Although the District operated efficiently overall, it needs to better ensure that its bus drivers meet all certification requirements and it may be able to reduce its plant operations costs by further reducing the amount it pays for custodial services.

In fiscal year 2011, Chinle Unified School District’s student achievement was similar to peer districts’ averages, and the District’s operational efficiency was mixed, with some costs higher and some costs lower than peer districts’ averages. The District’s per pupil administrative costs were much higher than peer districts’, and it lacked adequate controls over its vehicles, accounts payable processing, and computer systems. The District’s plant operations costs were also much higher than peer districts’ because the District maintained more building space per student, which was likely not needed since Chinle USD operated its schools far below their designed capacities. The District’s food service program was reasonably efficient, and its transportation program had similar per mile costs as peer districts’. However, the District did not meet bus driver and bus preventative maintenance requirements.

In fiscal year 2012, Clifton Unified School District’s student AIMS scores were lower than both its peer districts’ and state averages. The District’s instructional program needs improvement. For example, some students were not provided the statutorily required number of instructional hours, and one of its four teachers did not have a teaching certificate. The District’s operational efficiencies were mixed, with some costs higher and some costs lower than peer districts’. However, the District lacked proper oversight and adequate controls over nearly all of its operations. In particular, the District lacked basic administrative processes such as monitoring budgets and maintaining proper controls over expenditures resulting in it overspending its legal budget limits in fiscal years 2009, 2010, and 2011. The District also failed to meet several transportation safety requirements. For example, its primary driver was not certified to drive a school bus. Lastly, the District lacked proper supervision of inmate workers on its school campus.
