This Pipeline Protection and Integrity Plan outlines the potential failure modes and design considerations and environmental and spill control measures for pipeline construction and operation.
This technical memorandum describes an evaluation of the GoldSIM model seepage results incorporating additional seepage controls and Best Available Demonstrated Control Technologies (BADCT) such as “thin lift” deposition.
This technical memorandum summarizes the potential failure modes and other contributing risk factors to the Peg Leg TSF alterative that could lead to downstream impacts, and how those failure modes are addressed in design and the methodology.
The Peg Leg Pipeline Corridor (PLPC) DEIS study considered two potential pipeline corridor alignment options for transport of mill tailings from the West Plant concentrator site to the Peg Leg TSF and return of reclaim water from the Peg Leg TSF back to the West Plant concentrator site.
This report presents the Draft Environmental Impact Statement (DEIS) design for the Peg Leg Site Alternative 5 – Optimized. The site is located west of the Florence-Kelvin highway approximately 18 miles south of the Superior, Arizona mill site, as shown on attached drawing G-001.
This Field Summary Report describes the investigation tasks and activities associated with the Near West Tailings Storage (TSF) geotechnical investigation. The objectives of the investigation were to obtain data necessary to support the pre-feasibility design of the proposed Near West TSF, to obtain additional information to support hydrogeological characterization of the site, and to characterize potential borrow materials located near the TSF footprint.
Early on August 4, 2014, a tailings dam failure occurred at the Mount Polley Mine caused water and tailings to be released form the Tailings Storage Facility to Polley Lake, Hazeltine Creek and Quesnal Lake.
Resolution Copper Mining, LLC (RCML) is submitting for the Arizona State Mine Inspector’s review and approval this Mined Land Reclamation Plan (MLRP) for the Superior Mine in the area of Superior, Arizona.
This report is the 2012-2013 annual report on the field testing program for Resolution tailings. It also represents the conclusion of the project and the final evaluation of the leachate trends. The testing program, developed by Golder Associates Inc. (Golder) with Geochimica (Golder/Geochimica), included cleaner and scavenger tailings from the proposed Resolution Copper Project.
This tech memo presents the first update of the Groundwater Assessment prepared by Golder Associates on behalf of Resolution Copper Mining. This work is required as part of the Area-Wide Aquifer Protection Permit for the West Plant Site. Specifically, this tech memo partially fulfills APP Compliance Schedule Item (CSI) No. 2.
