Water Resources

The documents listed below are Baseline Reports categorized topically as water resources.

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds (UQC/DC). The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper (RC) for the Resolution mine project. The catalog was prepared by Montgomery & Associates (M&A) and WestLand Resources, Inc. (WRI) on behalf of RC.

RCM is committed to the prevention of discharges of oil or oily wastewater to navigable waters and the environment. RCM maintains the highest standards for spill prevention through regular review, updating, and implementation of this SPCC Plan for the RCM WPS.

The goals of the baseline surface water monitoring program are to: a) Refine understanding of surface water  occurrence, quantity, and quality within the study are b) Develop a baseline data set against which future potential impacts from mining may be measured, and c) Support development of an EIS.

In February 2010, Montgomery published a report entitled "Interim Results of Groundwater Monitoring, Upper Queen Creek and Devils Canyon Watersheds" (M&A 2010) which reported all hydrochemical and isotopic data available through the second quarter of 2009. The current report presents hydrochemical and isotopic data collected since M&A 2010 was published.

WestLand was retained to evaluate an approximately 560-acre private parcel for the presence of potential waters of the U.S.

WestLand was retained to evaluate two areas, the West Plant and East Plant Analysis Areas, totaling approximately 3670 acres, for the presence of potential waters of the U.S.

WestLand was retained to identify potentially jurisdictional waters within an approximately 45,000-acre analysis area, encompassing the Resolution operations and vicinity within Pinal and Gila Counties, Arizona. The delineation is intended to be used by RCM as a planning tool, allowing RCM staff to identify those surface water features where impacts may require permitting under Section 404 of the Clean Water Act.

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.

Resolution Copper Company commissioned Golder and Associates to establish a program for the collection of baseline surface water data near the future RCC mine and associated facilities.  The intended uses of the data are primarily to support and EIS, develop a sound conceptual site model as a basis for predicting future impacts, and document current conditions as a baseline for judging future impacts.
