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.

The purpose of the study is to assist counties, cities, towns, and tribal communities in addressing a broad range of multimodal transportation planning issues including roadway and non-motorized modes of travel. The principal purpose is to evaluate existing transportation deficiencies, recommend needed improvements, and develop a transportation plan to accommodate and guide future growth. The study will result in a Major Streets and Routes Plan that will serve as a guide to the development of the Town’s roadway network that will be constructed to meet anticipated development in the Town.

The purpose of this study was to develop a multi-modal transportation plan that outlines the region’s transportation priority projects and provides a plan for ultimate implementation. The transportation study was focused around identifying regional mobility needs that can accommodate the anticipated future population and employment growth. This transportation study is a joint effort of Navajo County, the City of Holbrook, the City of Winslow and the Arizona Department of Transportation to develop multi-modal transportation recommendations for the study area, Heber-Overgaard, Holbrook and Winslow over a 20-year planning horizon.

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 Southern Greenlee County Trails Study identified a framework of trails that could be developed to attract modern-day adventurers and naturalists to explore the rich natural and cultural heritage of Greenlee County. The study identifies trails that Greenlee County residents can use for recreation, enabling them to engage in healthy life choices with limited bike-car or pedestrian-car conflicts. Long dependent on mining as its economic base, this trails plan is another step Greenlee County is taking to diversify its economy by increasing tourism.
