Addendum #1 to October 28, 2020 Process Memo “Cumulative Effects Analysis Overview and Screening by Resource”

The purpose of this addendum is to update the process memorandum dated October 28, 2020, titled “Cumulative Effects Analysis Overview and Screening by Resource.” The original process memo served to outline the methods and screening results used for the analysis of cumulative effects within the Environmental Impact Statement (EIS) prepared for the Resolution Copper Project by disclosing:

• Approach for addressing past and present actions in the EIS.
• Process used to identify valid reasonably foreseeable future actions (RFFAs).
• Summary of spatial analysis areas and temporal analysis time frames, by resource area.
• Screening of RFFAs by resource, and whether the RFFA should be assessed in the EIS cumulative effects analysis.

Since publication of the Final EIS in January 20211 , the RFFAs evaluated in the EIS required an update, as follows:

• Evaluate the status of all previous RFFAs evaluated in the EIS, primarily to determine their continued applicability for inclusion within the EIS cumulative impact analysis.
• Identify any new projects that have been introduced after October 28, 2020, and evaluate their validity as RFFAs for cumulative analysis in the republished EIS.
