Numerous agencies, companies, individuals, and organizations have collected the ambient air quality monitoring data presented in this report. The Arizona Department of Environmental Quality publishes data from these various sources to provide a picture, which is as complete as possible, of air quality conditions throughout Arizona.
States are required to complete and submit to the U.S. Environmental Protection Agency an annual network monitoring plan. This plan informs the EPA of the monitoring activities ADEQ has implemented each year.
Provides individuals and companies anticipating mineral exploration or mining in Arizona with a clear picture of the permitting process. This document is an honest attempt to present all the permits that may be required by a mining operator in Arizona.
This directory contains a listing of Arizona-registered consultants for the following mining related disciplines: assayers, geological engineers, geologists, geophysical engineers, metallurgical engineers, and mining engineers.
Testimony for The Subcommittee on National Parks, Forests and Public Lands of the Committee on Natural Resources presented against the withdrawal of the uranium-bearing lands around the Grand Canyon National Park.
This report, a companion to Open File Report 90-5, Publications of the department of Mines and Mineral Resources from 1939 to 1990, is a serial listing of the publications of the Department from September 1990 to December 2004.
This article studies the characteristics of modern Arizona mining scams or nontraditional mining projects and describes a number of examples. The purported mines or properties were located in Arizona, or the schemes had other substantial ties to the state.
The revision is a separate document to the Arizona Regional Haze State Implementation Plan submitted December 2003. The Revision meets specific commitments outlined in the December 2003 SIP (Enclosures 2 through 7) as well as a correction to the authorizing regional haze statutes. The submittal contains a SIP completeness checklist and seven enclosures.
This document includes an attainment demonstration and formal request to the United States Environmental Agency to redesignate the San Manuel, Arizona area, a nonattainment area for sulfur dioxide (SO2), to attainment for the health-based 24-hour average and annual average SO2 National Ambient Air Quality Standards (NAAQS). It summarizes the progress of the area in attaining the SO2 standard, demonstrates that all Clean Air Act requirements for attainment have been adopted, and includes a maintenance plan to assure continued attainment after redesignation.
In a rule published July 2, 2002, EPA found the Arizona Department of Environmental Quality’s "Plan for Attainment of the 24-Hour PM10 Standard – Maricopa County PM10 Nonattainment Area" (May 1997), inadequate to achieve attainment of the 24-hour National Ambient Air Quality Standards for particulate matter 10 microns or fewer in aerodynamic diameter (PM10) at the Salt River monitoring site. The 1997 ADEQ SIP revision included attainment and Reasonable Further Progress demonstrations for the 24-hour NAAQS at the Salt River air quality monitoring site of the Maricopa County PM10 Serious Nonattainment Area, as well as at three other monitoring sites in the Phoenix area, - the Maryvale, Gilbert, and West Chandler sites. On August 4, 1997, EPA approved ADEQ’s attainment and RFP demonstrations for the Salt River monitoring area, which showed that the 24-hour PM10 NAAQS would reach attainment in the area by May 1998. Due to continuing violations of the 24-hour PM10 NAAQS at the Salt River air quality monitoring site since May 1998, EPA subsequently required Arizona to submit a revision to correct SIP inadequacies. This document consists of Arizona’s revisions to the state implementation plan for the Maricopa County PM10 Serious Nonattainment Area as described by EPA in its Federal Register notice of disapproval.
