On the night of August 3-4, 2014, the dam enclosing the tailings storage facility (TSF) at Mount Polley Mine, a copper and gold mine in interior British Columbia, failed.

At this time, there is a crisis associated with concern over the safety of tailings dams and lack of trust in their design and performance. This crisis has resulted from recent high-profile failures of dams at locations with strong technical experience, conscientious operators, and established regulatory procedures.

The purpose of this process memorandum is to describe additional supporting resource information in detail. The Soils and Vegetation section of Chapter 3 of the draft EIS (DEIS) includes brief summaries of the information contained in this process memorandum.

Critical evaluation of existing empirical evidence to test whether there was a gradation in nest success as a function of distance from an edge. Researchers investigating this question have been inconsistent in their experimental designs, making generalizations about edge-effect patterns difficult.

The purpose of this document is to provide personnel in all areas of the Resolution Copper Mining LLC (RCM) operation access to procedures for the proper handling and disposal of hazardous materials and hazardous waste so as to protect the environment and to comply with laws and regulations.

The objective of the surveys within the Mineral Creek watershed during 2009 were to document occurrence of Gila chub and other fish species within perennial waters in Devils Canyon and the portion of Mineral Creek between Big Box Dam and the ASARCO Ray Mine tunnel.

Surface soil reclamation is used to increase the re-establishment of native vegetation following disturbance through preservation and eventual replacement of the indigenous seed reserves. Employed widely in the mining industry, soil reclamation has had variable success in re-establishing native vegetation in arid and semi-arid regions.

The purpose of this process memorandum is to provide an overview of these potential effects and outline approaches to assess these risks in the draft environmental impact statement (EIS).
