Welcome to the public website for the Pinto Valley Mine Environmental Impact Statement (EIS). This site provides information on the Pinto Valley Mine Environmental Impact Statement (EIS) and public involvement.
On November 3, 2021, Tonto National Forest Supervisor Neil Bosworth signed and approved an updated Pinto Valley Mine plan of operations for activities on National Forest System lands related to the Pinto Valley Mine in Miami, Arizona. Approval of the revised plan allows for Pinto Valley's continued operation for approximately 19 additional years. In accordance with the Pinto Valley Mine record of decision dated August 19, 2021, the final plan includes additional environmental controls as well as monitoring and mitigation measures to address potential environmental impacts from the mine's operations.
On August 20, 2021 the Forest Service released the Record of Decision for the Pinto Valley Mine. This Record of Decision documents the Tonto National Forest's Forest Supervisor's decision, along with the rationale for the decision and alternatives considered in reaching the decision. It also includes a discussion of mitigation and monitoring measures that are deemed necessary by the Tonto National Forest to meet the requirements of the regulations at 36 CFR 228, subpart A and to comply with other applicable laws and regulations. The Record of Decision is the National Environmental Policy Act decision and is not authorization or a permit to operate. Pinto Valley Mining Corp. will need to meet the conditions in the Record of Decision prior to written approval to operate on National Forest System lands.
On August 9, 2021 the Regional Forester issued an objection response letter that included instruction for the Tonto National Forest to make several clarifications and corrections in the final ROD and/or in an Errata to the final EIS. The Tonto National Forest has addressed the instructions in the objection response letter and the final EIS Errata and is therefore proceeding with having the Forest Supervisor sign the final ROD. Refer to the Public Involvement Page for more information.
Tonto National Forest (Tonto) officials released the final EIS along with a draft Record of Decision (ROD) for the Pinto Valley Mine project on April 9, 2021.
Pinto Valley Mine is an existing open pit copper and molybdenum mine on private lands and National Forest System lands. Pinto Valley Mining Corp's mining plan of operations requests a consolidation of prior expired and/or non-transferable authorizations for surface disturbance of National Forest System lands, further expansion of mining operations onto National Forest System lands, and incorporation of legacy encroachments. The proposed mining plan of operations would result in authorization of 566 acres of existing disturbance on public land and about 229 acres of new disturbance on public lands and would extend the mine's life for approximately 19 years.
