The purpose of this process memorandum is to document the Potential future measures that have
now been removed from the FEIS.

The PLANTS Database provides standardized information about the vascular plants, mosses, liverworts, hornworts, and lichens of the U.S. and its territories.

This memorandum documents a review of the Action Alternatives contained in the 2025 Final EIS (FEIS) for the Resolution Copper Project and Land Exchange (Resolution) for consistency with the December 2023 Tonto National Forest Land Management Plan (forest plan).

This environmental impact statement documents analysis of impacts of four alternatives developed for programmatic management of the nearly three million acres administered by the Tonto National Forest.

The purpose of this investigation was to assess the Property and surrounding areas to identify the presence or potential presence of recognized environmental conditions (RECs) potentially resulting in environmental impacts to the Property.

This Ecological Overview was prepared for approximately 160 acres (65 hectares) in Gila and Pinal counties, Arizona. The Dripping Springs parcel is a private inholding within the Bureau of Land Management (BLM) lands (and adjacent to Arizona State Trust Lands), located along the Dripping Spring Mountains about 8 miles (13 kilometers [km]) north of the town of Hayden.

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek, Devils Canyon, Mineral Creek, and Dripping Springs Wash watersheds.

The evaluation reaffirms the conclusions of the DEIS that the National Ambient Air Quality Standards (NAAQS) will not be exceeded – including when using the mining-sector specific average silt content values recommended by EPA.

Five-Year Probabilistic Projections of future conditions in the Colorado River system currently extend through 2027. They are typically updated every January, April, and August, while probabilistic results for the 2-year period are updated every month. The 5-Year Probabilistic Projections are generated using the Colorado River Mid-Term Modeling System (CRMMS) in Ensemble Mode.

SWCA and TNF have completed reviews and analysis to determine whether reinitiation of Section 7 consultation under the ESA is warranted, and this technical memorandum outlines the various changes that could potentially warrant reinitiation of Section 7 consultation with the USFWS.
