Welcome to the public website for the Pinto Valley Mine Environmental Impact Statement (EIS). This site provides information on the Pinto Valley Mine EIS and public involvement.
The Pinto Valley Mine is an existing open pit copper and molybdenum mine located approximately 8 miles west of Miami, Arizona in Gila County. Pinto Valley Mining Corp. is proposing to expand mining activities onto the Tonto National Forest, extend the mine life to 2039, and to consolidate previous and ongoing authorizations for the mine. The proposed project would result in an estimated 1,011 acres of new disturbance (245 acres on Tonto National Forest land and 766 acres on private land owned by Pinto Valley Mining Corp.). The EIS will evaluate and disclose the potential environmental effects from approval of the Mining Plan of Operations for activities on the Tonto National Forest. The EIS also will evaluate any necessary amendments to the Tonto National Forest Land and Resource Management Plan.
The Tonto National Forest released a Draft EIS on Dec. 13, 2019, initiating a 45-day public comment period that concluded Jan. 27, 2020. Tonto staff held two public meetings -- Jan. 7 in Superior, Arizona, and Jan. 8 in Miami, Arizona -- to answer questions regarding the project.
The first half of 2020 will involve meetings and discussions between the Forest Service project team and the environmental consultant to the Forest Service. Together, they will evaluate which substantive comments warrant additional analysis prior to the release of the Final EIS. The Forest Service anticipates releasing the Final EIS and Draft Record of Decision (ROD) to the public in fall 2020, and releasing the Final ROD in winter 2020.
