Pima County Department of Environmental Quality monitors ambient (outdoor) air pollutants throughout eastern Pima County, including the Tucson metropolitan area and Green Valley. There are six principal pollutants, called “criteria” pollutants that are monitored in accordance with the National Ambient Air Quality Standards set by the Environmental Protection Agency to comply with the Federal Clean Air Act. These standards were established to protect public health and the environment from harmful levels of air pollution.

The Pima County Department of Environmental Quality has prepared this document to be submitted to the U.S. Environmental Protection Agency, Region IX. The purpose of the Ambient Air Monitoring Network Plan is to determine if the network is achieving the air monitoring objectives specified in 40 CFR Part 58 Appendix D, which mandate adherence to certain number, type and location requirements of monitoring sites and specific site criteria such as monitoring inlet height. The review should also determine if modifications should be made to the network (e.g. through the termination or relocation of unnecessary stations or addition of new stations). In addition, the review is necessary in order to ensure that the residents of Pima County are provided adequate, representative and useful air quality data, and to provide adequate protection to public health.

With the passage of the Federal Endangered Species Act in 1973, the stage was set for a confrontation between urban development and the provisions of Federal Law. Language was amended to the Act that established standards that a plan would have to meet before the Fish and Wildlife Service could approve it and issue a permit for the take of a listed species. In those jurisdictions that have adopted this approach, conservation of natural resources is no longer an afterthought but a major element that has to be considered during the regular land use permitting process.

Pima County is endowed with many mineral resources, not only copper mines, but also the important products such as sand, gravel, and limestone used everyday in supporting the infrastructure of our cities. It is essential that these mineral resources, and the lands where they occur, remain available for exploration and development. This report presents an assessment of the mineral resources of Pima County based on hard data derived from many experienced geologists working in the private sector and from publications of state and federal government agencies.

Afterschool youth-development programs (AYDs) have grown significantly during the past 15 years in Arizona and nationally. Many providers have moved beyond simply providing a safe haven to actively promoting young people’s development. However, there is still tremendous opportunity for growth. There is also a continuing need to enhance coordination and collaboration among programs in order to extend their resources and heighten their impact.

Morrison Institute worked with AzCASE and VSUW to construct a 55-question survey using Qualtrics on-line software. While the term “afterschool” was used, the survey was designed to measure all types of out-of-school programs, regardless of whether they operate before or after school, on weekends, or during school and summer breaks. Approximately 1,800 questionnaires were distributed to individual program sites in Maricopa and Pima counties via a list provided by AzCASE. Though the survey did not utilize a random sample, its 38 percent response rate (681 returns) suggests that its findings can help educators, youth-development professionals, policymakers and the business community understand the scope, characteristics and needs of afterschool services in Arizona’s two largest population centers.
