A benchmark survey was conducted by MAG and ADOT in December of 2006 to determine initial attitudes and awareness of litter issues in Arizona and to evaluate littering behavior. A follow-up survey was then conducted in July 2008, at the end of the first two years of the campaign, to determine if any changes in awareness, attitudes or behavior were realized. Subsequent follow-up studies focused on Maricopa County residents.

An update to the Flagstaff Regional Plan 2030 (FRP30), to bring its Road Network Illustration (Map 25) into compliance with Arizona Revised Statute requirements and to resolve inconsistencies between Map 25 and parts of the Flagstaff City Code. This update does not alter the intent of FRP30; it is only concerned with correcting errors, removing legal vulnerability, and improving the readability of FRP30.

The proposed action is the construction and operation of a new multilane freeway in the metropolitan Phoenix area extending approximately 22 to 24 miles from Interstate 10 west of Phoenix to Interstate 10 southeast of Phoenix. The facility would be the final extension of State Route 202L, an element of the Maricopa Association of Governments’ adopted Regional Freeway and Highway System, as outlined in its Regional Transportation Plan.

This report documents the efforts of the Arizona Department of Transportation to implement the American Association of State Highway and Transportation Officials DARWin‐ME pavement design and rehabilitation guide. As part of this implementation, the research team also prepared a practical stand‐alone user’s guide that provides guidance for obtaining inputs, conducting design, and establishing the recommended pavement design.

The Mexican gray wolf subspecies was listed as endangered in 1976. In 1998 a nonessential experimental population was established in New Mexico and Arizona. Eleven captive-born and reared animals were released into the Blue Range Wolf Recovery Area. In June 2007, the U.S. Fish and Wildlife Service contracted with D.J. Case and Associates to assist in planning and implementing public input for a scoping process to identify issues to consider in developing alternatives preparatory to development of a new Environmental Impact Statement for the Mexican gray wolf introduction program.

This report evaluates the potential exposure pathways associated with vermiculite concentrate processing activities at the Ari-Zonolite facility. The site is located in the near downtown area of Glendale, approximately ½ mile from the city hall, downtown shops, and other buildings. The former Ari-Zonolite facility received vermiculite from the Libby, Montana, mine. From 1951 to 1964, the site was leased the site to the Ari-Zonolite Company. Following the removal of the vermiculite concentrate processing equipment in 1964, several businesses have occupied the site. None of these businesses were involved in vermiculite processing activities. The last occupant of the former vermiculite processing building was an automotive restoration business, which vacated the site in 2002.

The objective of this assessment is to evaluate whether a public health hazard exists as a result of environmental exposures in Hayden and Winkelman, Arizona, located near a smelter operated by ASARCO, Inc. Some of the residents of these towns have expressed concerns that metals from smelter emissions over the years have been causing health problems. This report uses environmental data collected from water, soil, and air in the Hayden and Winkelman area to estimate environmental exposures. The study also evaluates available health outcome data from previous epidemiological and biological-monitoring studies conducted in the area. The report concludes that exposure to sulfur dioxide occasionally poses a short-term public health hazard to sensitive asthmatics. These episodes of higher levels of sulfur dioxide occur infrequently. They do not appear to pose a health hazard to persons without sensitive airways or asthma. Other environmental exposures do not appear to pose a public health hazard.

In March 2004, a resident of Cornville contacted the Arizona Department of Environmental Quality to request information on arsenic in drinking water. The resident collected six well water samples from their own well and neighbors’ wells and submitted them to a private laboratory for arsenic analysis. The analyses detected arsenic ranging from 15 to 952 μg/L. ADEQ and the community members asked the Arizona Department of Health Services to provide health information about using the water. Initial conversations with the well owner and other community members revealed that many people had concerns about potential health effects from arsenic exposure.
