This report examines community concerns and challenges related to extreme heat during a typical year and during the COVID-19 pandemic. It considers which policies have helped address these concerns and challenges and identifies potential opportunities to further support community members with the challenge of extreme heat. The report focuses specifically on American Indian and Latino/a community members, given their disproportionate risk of experiencing detrimental impacts of extreme heat and overlapping risk factors for negative outcomes of COVID-19.

If Arizona is to prosper into the next century, our focus needs to turn to what is essential for our future: The preservation of our groundwater and our increasingly fragile aquifers. This analysis shows that Arizona continues on a path of unsustainable groundwater use that threatens the health and welfare of our state. It is not too late for a course correction, but that will require that Arizonans face the truth and make bold choices.

The Clean Air Act states that an area can be redesignated to attainment if specific conditions are met. This document demonstrates that all CAA requirements for attainment have been met, summarizes the progress of the area in attaining the PM10 standard, demonstrates that the Bullhead City area qualifies for EPA’s Clean Data Policy and Limited Maintenance Plan option, and includes a maintenance plan to assure continued attainment for ten years after the redesignation. This document includes a formal request to the U.S. Environmental Protection Agency to redesignate the Bullhead City, Arizona PM10 nonattainment area to attainment for the health-based 24-hour average and annual average PM10 National Ambient Air Quality Standard.

In addition, this document includes a formal request to revise the nonattainment area boundary, as currently defined in 40 CFR 81.303, to exclude three townships (108 square miles) in the east and south of the nonattainment area. The rationale for eliminating the three townships is that the land contains undisturbed desert terrain. The majority of the three townships is federal land managed by the Bureau of Land Management and state land managed by the Arizona State Land Department. Analyses included in this document show that ambient air quality measurements have remained below the NAAQS for PM10, and both the 24-hour average design value and annual average PM10 design value are below EPA’s LMP allowable limits. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

This document consists of the attainment demonstration, maintenance plan, and redesignation to attainment request for the Douglas Sulfur Dioxide (SO2) Nonattainment Area. The purpose of this document is to demonstrate how the State of Arizona has met the National Ambient Air Quality Standards for SO2 and intends to maintain compliance with the NAAQS in the Douglas area. Air quality standards are divided into two types: primary standards based on health effects and secondary standards based on environmental effects such as damage to property, plants, visibility, etc. Both standards are established by EPA for criteria air pollutants such as sulfur dioxide.

This document includes an attainment demonstration and formal request to the United States Environmental Protection Agency to redesignate the Hayden, Arizona Sulfur Dioxide (SO2) Nonattainment Area to attainment for the health-based 24-hour average and annual average SO2 National Ambient Air Quality Standards. It summarizes the progress of the area in attaining the SO2 standards, demonstrates that all Clean Air Act (CAA) requirements for attainment have been adopted, and includes a maintenance plan to assure continued attainment after redesignation. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

This document is an attainment demonstration, maintenance plan, and formal request to the United States Environmental Agency to redesignate the Miami, Arizona area, a nonattainnlent area for sulfur dioxide (SO,), to attainment for the health-based 24-hour average and annual average SO, National Ambient Air Quality Standards. It summarizes the progress ofthe area in attaining the SO, standards, demonstrates that all Clean Air Act requirements for attainment have been adopted, and includes a maintenance plan to assure continued attainment after redesignation. This document also demonstrates that the emission reduction control measures responsible for the air quality improvement are both permanent and enforceable.

Miami, Arizona, is a historic copper mining town in Gila County, 80 miles southeast of Phoenix and 112
miles northeast of Tucson. Miami’s sister city, Globe, lies four miles to the east. The Hayden/Miami
Nonattainment Area was designated for nonattainment of the particulate matter National Ambient Air
Quality Standard by operation of law following the Clean Air Act amendments of 1990. In March, 2007, EPA approved a boundary redesignation of the Hayden/Miami PM10 nonattainment area into two separate, but adjoining, PM10 nonattainment areas. Together, these two new PM10 nonattainment areas cover the same geographic area as the original Hayden/Miami PM10 nonattainment area. This plan demonstrates that all CAA requirements for attainment and maintenance have been met and summarizes the progress of the area in attaining the PM10 standard. This plan also summarizes and demonstrates that the MNA qualified for EPA’s Clean Data Policy and the Limited Maintenance Plan option.

This document consists of the attainment demonstration, maintenance plan, and redesignation to attainment request for the Morenci Sulfur Dioxide (SO2) Nonattainment Area. The purpose of this document is to demonstrate how the area has met the National Ambient Air Quality Standards for SO2 and intends to maintain compliance with the NAAQS. Air quality standards are divided into two types: primary standards based on health effects and secondary standards based on environmental effects such as damage to property, plants, visibility, etc. Both standards are established by Environmental Protection Agency for criteria air pollutants such as sulfur dioxide.
