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.

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.

This document is designed to improve compliance with Maricopa County air pollution rules and regulations, with particular emphasis on Rule 310, which deals with fugitive dust sources, a major source of PM-10. It also describes control measures and work strategies that will assist in ensuring compliance with Rule 310. Also included in this report is a glossary of terms, a brief summary of applicable County air pollution regulations, and detailed information on the requirements for implementation of dust control practices.

Given the inevitable transportation changes associated with impending growth in Pinal County, there was a need for a method to assess how corresponding emissions changes might affect PM10 and Ozone concentrations in the county and at the monitor sites. The overall objective of the project was to develop methods or models that could be used in Pinal County to adequately address air pollution issues in the County.

This report is a reexamination of visitor data first reported in the multi-year "Survey of Visitors to Arizona’s Tribal Lands," which was commissioned by the Arizona Office of Tourism and conducted in 2004-05 by the Arizona Hospitality Research and Resource Center at Northern Arizona University. That study, released in December 2005, analyzed visitor data collected for eight Arizona American Indian tribes and presented that data in aggregate for all tribes. This report, on the other hand, disaggregates that original database to take a more in-depth look at visitor patterns at Rural versus Metro tribes in Arizona.

Generally, this second study found that visitors to Rural and Metro tribes in Arizona are similar in many ways – parties of two persons; parties composed largely of family members; similar educational and income levels; private vehicles as travel mode; similar sightseeing and cultural/heritage activities; similar information sources; relatively high satisfaction levels; and, many similar shopping purchases. The survey also found some significant differences, however, including the following: Travel parties visiting Rural tribes contained more children, more Arizona residents, and had higher numbers of repeat visitors. Visitors to Rural tribes were also more likely to describe the tribe as their main destination; were more likely to engage in recreation and outdoor activities; stayed longer; and, consequently had higher spending. Visitors to Metro tribes were slightly older and visited the tribe as one stop on a longer trip. Visitors also reported slightly higher satisfaction levels at Metro tribes.

A survey of visitors to Native American tribal lands in Arizona was commissioned by the Arizona Office of Tourism and conducted by NAU’s Arizona Hospitality Research & Resource Center in 2004-2005. This research constituted the first major study of visitors to Native American tribes in Arizona and possibly in the Southwest. This final report, Survey of Visitors to Arizona Tribal Lands, provides first-ever baseline visitor data, presented in aggregate for the eight participating Arizona tribes. The study found that visitors to these Native American tribes in Arizona are slightly older, have higher annual incomes, stay longer, and have higher daily expenditures (for lodging, shopping and entertainment) than Arizona visitors generally. Visitors to Arizona’s tribes are also more interested in cultural and historic activities, shopping for arts and crafts, educational experiences and sightseeing than are visitors overall. They are also highly satisfied with their visits to Native American tribal lands.

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.
