Baseline Reports

An evaluation of an approximately 14,273-acre area for the presence of potential waters of the U.S.

This technical memorandum was prepared to document results and analysis of a 90-day aquifer test conducted by RCM at well HRES-20 completed in the Apache Leap Tuff (ALT) aquifer.

This plan describes the procedures followed by RCM for the EPS activities to prevent, control, and mitigate releases of oil and petroleum products to the environment at its RCM EPS located near the Town of Superior, in Pinal County, Arizona.

Flooding is among the worst natural disasters responsible for loss of life and property in Arizona, underscoring the importance of accurate estimation of flood magnitude for proper structural design and floodplain mapping. Twenty-four years of additional peak-flow data have been recorded since the last comprehensive regional flood frequency analysis conducted in Arizona. Periodically, flood frequency estimates and regional regression equations must be revised to maintain the accurate estimation of flood frequency and magnitude.

This plan describes the procedures followed by RCM for the WPS activities to prevent, control, and mitigate releases of oil and petroleum products to the environment at its RCM WPS located near the Town of Superior, in Pinal County, Arizona.

This report summarizes the meteorological, nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona for the fourth quarter, October 1-December 31, 2013.

Avian surveys were conducted in support of the proposed Near West tailing alternatives areas. WestLand and BIOME biologists conducted avian surveys designed to provide information on the avian species occurring in the vicinity of the Analysis Area and to determine the presence of Tonto National Forest sensitive and management indicator species, as well as species protected under the Migratory Bird Treaty Act.
