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.

In fiscal year 2012, Scottsdale Unified School District’s student achievement was similar to peer districts’, on average, but it compared less favorably in operational efficiencies. The District’s food service program operated efficiently with a cost per meal that was lower than the peer district average. However, the District’s administrative costs were higher than peer districts’, primarily because it employed more administrative staff. In addition, the District inaccurately reported its costs on its Annual Financial Report and it lacked sufficient computer controls. The District’s plant operations cost per pupil was higher than peer districts’, on average, because the District maintained more square footage per student than the peer districts’ and many of its schools operated far below their designed capacities. Further, the District’s transportation cost per mile was much higher than the peer districts’ average, in part, because of inefficient bus routes.

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.
