General Plan of Operations (GPO)

In November 2013, Resolution Copper Mining, LLC (RCM) submitted the proposed General Plan of Operations (GPO) to the Tonto National Forest, to develop and mine a copper-molybdenum deposit. Tonto National Forest deemed the GPO to be complete in December 2014 - see Letter of Completion. A plan of operations is a Forest Service permit, which authorizes mining operations on national forest lands. The first step in the approval process for a plan of operations is submittal of a proposed plan of operations to the Forest Service. The Forest Service then analyzes the proposal and conducts a NEPA analysis. At this time, the GPO is just a proposal submitted by RCM. The final Plan of Operations will not be produced until the EIS is complete and the Record of Decision is signed by the Forest Supervisor.

Notice of Intent (NOI)

The Notice of Intent (NOI) to Prepare an Environmental Impact Statement, Request for Comments, and Notice of Public Scoping was published in the Federal Register on March 18, 2016. Publication of the NOI represents the official start of the process to prepare an EIS, as required under the National Environmental Policy Act, for approval of a plan of operations for the Resolution Copper Project and associated land exchange. Publication of the NOI also starts the 60-day public scoping period. However, please note that as of April 4, 2016, the Tonto Forest Supervisor has extended the Public Scoping Period for an additional 60 days. The last day to submit comments will now be July 18, 2016. A Notice of Extension was published in the Federal Register on May 25, 2016.
