ADEQ meteorologists issue air quality forecasts for pollutants such as ozone and particulate matter based on data collected at state-monitoring sites. These forecasts help inform the public when unhealthy pollution levels are anticipated | View Forecasts >
Nonattainment areas are classified by the Environmental Protection Agency (EPA) to have air quality monitoring data for criteria pollutants above the National Ambient Air Quality Standards (NAAQS) outlined in the Clean Air Act. These areas are designated conservatively and are not necessarily exceeding | Learn More >

Leaking USTs in Arizona
The following map shows where confirmed leaking UST sites requiring cleanup are located in Arizona. Please note the name of the current facility is listed on the map; due to business and property sales over time, the current facility may not be the responsible party at the time the leak occurred.

Site/Facility of Interest
Facility Information
The Copper World Project is located approximately 28 miles southeast of Tucson, Arizona in Pima County and about 12 miles southeast of Sahuarita, Arizona. The Copper World Project will be developed as an open-pit mining operation. Both sulfide and oxide ore will be mined and beneficiated. The project will include a milling and flotation circuit for the processing of sulfide ore, along with conventional tailings disposal. A heap leach facility (HLF) is planned that includes a lined heap leach pad (HLP) and associated lined ponds for the leaching of copper from oxide ore. The project also includes a solvent extraction and electrowinning (SX-EW) plant for processing of copper-rich solutions from the heap leach circuit and from a separate copper concentrate leach circuit. Sulfuric acid will be produced by an onsite sulfuric acid plant.

Background
In September 2023, ADEQ issued a Notice of Violation (NOV) to MRI based on a determination that the company did not have the appropriate air quality permit for its operations. At that time, MRI was operating under a General Air Quality Permit for Crushing and Screening. The NOV required the company to submit an application for an Individual (Class II) Air Quality Permit. Due to the extensive timeframe and process for considering and reaching a decision on the new permit application required, ADEQ and MRI agreed to enter into a legally binding agreement called a Consent Order. The Consent Order was executed on Oct. 12, 2023, and specified interim, stringent operational limits and air pollution control requirements that MRI must implement at the facility to protect public health. ADEQ terminated this Consent Order on Feb. 21, 2024, revoking MRI's authorization to operate its Cottonwood facility based on certified results that showed the facility failed a performance test. This failed performance test indicated the facility was not meeting a strict emission limit condition in the Consent Order. ADEQ believed this termination effectively revoked MRI’s right to operate its facility.
In response to ADEQ’s termination of MRI’s Consent Order, MRI served ADEQ with a lawsuit, including a request for a temporary restraining order, in Yavapai County. After evaluating its legal options to this lawsuit, ADEQ entered into a settlement agreement with MRI on Feb. 28, 2024, and revoked MRI’s coverage under the General Air Quality Permit for Crushing and Screening. Under state law (Arizona Administrative Code R18-2-510(d)), pursuant to ADEQ’s General Permit coverage revocation, MRI has the legal ability to operate its plant under the shield of its pending Individual (Class II) Air Quality Permit application that was submitted to ADEQ on Oct. 31, 2023 and subsequently deemed complete.
MRI’s operations must be conducted in accordance with all applicable state and federal Clean Air Act requirements. ADEQ will continue to conduct required onsite inspections to ensure the facility’s operations maintain compliance.
