The purpose of this Site Characterization Report is to provide a summary of existing relevant environmental data to characterize smelter affected soil at the West Plant Site, and to evaluate that data for use in the development of human health risk-based site-specific soil remediation standards (SSSRLs) for the West Plant Site.

The Pinal County Comprehensive Plan is the landmark document that will serve to steer the County on a positive course of action to manage growth, preserve the quality of life, and promote sustainability. It is a long-term vision that promotes effective economic vitality while ensuring environmental stewardship. The Plan articulates the vision and outlines the strategic direction to position Pinal as a vibrant, healthy, and economically sustainable region within the state of Arizona.

The Biological Evaluation (BE) supports the proposed baseline hydrologic and geotechnical testing and monitoring activities (the Proposed Action).

The Census Bureau releases two reports every year that describe who is poor in the United States. The first report calculates the nation’s official poverty measure based on cash resources. The second is known as the supplemental poverty measure (SPM) and takes account of cash resources and noncash benefits from government programs aimed at low income families.

This technical memorandum has been prepared to summarize results of drilling, construction, and testing at hydrologic test wells HRES-16, HRES-17, and HRES-18. The wells were installed to characterize hydrogeologic conditions in the Apache Leap Tuff (ALT) on the east side of Devils Canyon near the JI Ranch Fault. HRES- 16 is a larger diameter well (nominal 8-inch) that was completed to provide a location for longterm aquifer testing in the ALT aquifer. Monitoring data obtained from HRES-16, HRES-17, and HRES-18 have been incorporated into the RCM hydrologic monitoring program.

Arizona hedgehog cactus surveys conducted in the vicinity of East Plant, along portions of the existing Magma Mine Road, and along the proposed re-alignment of Magma Mine Road.

This technical memorandum presents the results from the static geochemical characterization program of cleaner and scavenger tailings for the Resolution Copper Project .
