This document is intended to give an overview of the Federal-Aid Program and its impacts on Arizona. There are four major sections in the report: (1) Overview of the Federal-Aid Program; (2) Arizona Federal funding highlights for the fiscal year; (3) Federal-aid Highway Program Characteristics; and (4) Federal-Aid Highway Program descriptions. The first section gives a general overview of how the Federal-Aid Program is financed, the authorization process and a discussion of the apportionment, allocation and obligation authority processes. The second section deals with Arizona Federal funding highlights the for fiscal year. The last two sections are devoted to characteristics of the core programs, including eligibility, limitations, apportionment formulas and descriptions of the funding categories.

Since 1986, the Arizona Department of Transportation has used a comprehensive regression-based econometric model to estimate Transportation Excise Tax revenues for Maricopa County. These revenues, which flow into the Regional Area Road Fund (RARF), are the major funding source for the Maricopa County Freeway Program. This document contains the official forecast of expected values for the Maricopa County Transportation Excise Tax as developed by the Arizona Department of Transportation in cooperation with the Maricopa Association of Governments, Valley Metro and Valley Metro Rail.

The Maricopa County Transportation Excise Tax, often referred to as the “1/2 cent sales tax” is levied upon business activities in Maricopa County, including retail sales, contracting, utilities, rental of real and personal property, restaurant and bar receipts, and other activities. Transportation excise tax revenues are deposited in the Maricopa County Regional Area Road Fund (RARF) which is administered by the Arizona Department of Transportation. These revenues were the principal source of funding for the Regional Freeway System in Maricopa County and were dedicated by statute to the purchase of right-of-way, design and construction of new freeways, widening of existing freeways and highways, improvements to the arterial street system, regional bus service and high capacity transit services such as light rail.

The State of Arizona taxes motor fuels and collects a variety of fees relating to the registration and operation of motor vehicles in the state. These collections include gasoline and use fuel taxes, motor carrier fees, vehicle license taxes, motor vehicle registration fees, and other miscellaneous fees. These revenues are deposited in the Arizona Highway User Revenue Fund and are then distributed to the cities, towns and counties of the State and to the State Highway Fund, which is administered by the Department. These taxes and fees represent a source of revenues available to the state for highway related expenses.

A resident of Wickenburg, Arizona and her husband reported experiencing some adverse health effects that she felt may be attributed to a recent pesticide application to her home. The family requested the Arizona Department of Health Services to evaluate whether the remaining levels of pesticides present in her home would cause any health effects. The resident reported to ADHS that their symptoms continued to worsen over time, and that the chemical continued to pool in their house even after being wiped up several times, so that she and her husband vacated the house. The couple underwent extensive testing, and are receiving oxygen treatment to alleviate their symptoms. No medical records have been submitted to ADHS for review, and it is difficult to conclusively analyze health outcome information as it has been self reported.

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.

The Arizona Department of Environmental Quality (ADEQ) requested the Arizona Department of Health Services to determine whether exposure to tetrachloroethylene (PCE) in the indoor air of a vacant dry cleaning facility and an attached convenience store posed a health threat to workers renovating the former dry cleaners and the patrons and employees of the convenience store. The former Viking Cleaners operated from 1954 until 2000. The building houses two businesses, Viking Cleaners, which is currently vacant but under renovation, and an attached convenience store that is currently in operation.

The purpose of this document is to summarize the body of environmental health investigation work that has been developed for the airport site. The report includes a summary of previous reports and new data. There is currently no exposure of public health concern. However, no regulation prevents persons from installing private drinking water wells in the contaminated groundwater. Because the pollutants in the groundwater may be of public health concern if it were used for drinking water, the site may pose a potential public health hazard unless actions are taken to prevent such use.

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.
