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.

Local residents expressed their concerns regarding the tailings from the Iron King Mine and Humboldt Smelter at Dewey-Humboldt, AZ. The purpose of this health consultation is to evaluate the available water and soil sampling results to determine if the detected metal levels pose adverse health effects when residents come into contact with the water or soil. In 2008, EPA initiated the field investigation portion of the Remedial Investigation and Feasibility Study for the Site. The primary objectives of the RI/FS are to determine the nature and extent of contamination and to gather sufficient information so that EPA can select a long-term remedy that eliminates, reduces, or controls risks to human health. The investigation included the collection of airborne particulates, groundwater, surface water, surface soil, subsurface soil, and sediment data across the entire Site. Data from the RI/FS was not available at the time the health consultation was prepared and thus it was not incorporated into this health consultation.

The Arizona Department of Health Services received a request for a Health Consultation from the City of Litchfield Park, dated March 5, 2007. The nature of the request was for ADHS to determine if there was a risk to public health from eating fish taken from Tierra Verde Lake. The City sponsors an annual fishing derby and believed that some citizens were eating the fish they caught. The City tested their lake water and for the very first time, measurable amounts of perchlorates were detected. The probable source for the perchlorates was thought to be from a groundwater, contaminant plume originating from the Phoenix Goodyear Airport Superfund Site.

This report presents an assessment of human health risks from exposure to surface soil metals in the Old Tungsten Mill, Tucson, AZ. City of Tucson officials had planned to build a park, on a parcel of land they owned west of Silverbell Road and north of Speedway Boulevard in Tucson, Pima County, Arizona. They had raised $200,000 in bond money to study what was the Old Tungsten Mill site when they found high levels of contaminants in the soil. The Arizona Department of Health Services, Risk Assessment & Health Consultation Program offered assistance to the city. On October 13th, 2006 City Officials asked ADHS to perform a health consultation to evaluate whether exposure to contaminants in soil pose a public health hazard, either currently or during possible future reuse of the land.
