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 Agency for Toxic Substances and Disease Registry has asked the Arizona Department of Health Services, Office of Environmental Health, to conduct a health assessment for the off-site residential area located adjacent to the Tucson Industrial Center, also known as the 3 Hangars site, within the larger Tucson International Airport Area Superfund site, in Tucson, Arizona. Previous investigations found that elevated levels of polychlorinated biphenyls (PCBs) in the drainage areas at the TIC site had migrated off-site into residential areas presenting a health threat to residents. The purpose of this Public Health Assessment is to evaluate if a public health hazard still exists since the remediation activities have been conducted at the off-site El Vado residential area. ADHS concludes that no current public health hazard exists as a result of ingestion, dermal, or inhalation exposures by residents, children, or transients to the post remediated soil in the residential areas on El Vado Road. Replacement of the top soil with certified clean soil has removed all contact with the soil containing PCBs eliminating any future public health hazard.

The United States Environmental Protection Agency asked the Arizona Department of Health Services, Office of Environmental Health, to provide an evaluation of the health hazards that may result from exposure to soil and soil gas contaminants present on the West-Cap site, located just north of the Tucson International Airport. Improper waste disposal practices from previous industrial activities at the site have resulted in contamination of on-site soil and soil gas. The objective of this health assessment is to assess the potential adverse health impact to on-site workers from exposure to the on-site contaminated soil and soil gas. Community exposures are not presented in this public health assessment.

This public health assessment evaluates the potential public health hazard from exposure to contaminated groundwater in the vicinity of the Tucson International Airport. The Tucson International Airport Area superfund site consists of a main plume of contaminated groundwater and three smaller areas of groundwater contamination east of the main plume. This report focuses on one of these areas of contamination called Plume B and evaluates the public health hazard posed by Plume B to residents of the area of south Tucson bounded by Valencia Road, Campbell Avenue, Irvington Road, and 6th Avenue.

The Arizona Department of Environmental Quality asked the Arizona Department of Health Services to evaluate the health threat to residents from exposures to ash fallout from a fire at an asphalt plant located on the Salt River Indian Reservation in Mesa, Arizona. The facility has recently been bought by Vulcan, Inc. The site is located just north of the Salt River between Dobson and Alma School Roads. April 13, 1999.
