Baseline Reports

A probabilistic seismic hazard analysis (PSHA) and deterministic seismic hazard analysis (DSHA) were performed for Resolution Copper’s Mine site including the area above the deposit (Mine area) and the area covering the East Plant site (Shafts 9/10).

This report summarizes the meteorological, upper-air (SoDAR¹), nitrogen dioxide (NO_²), 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 through December 31, 2017.

This screening analysis was prepared to determine the potential for occurrence of special-status species and/or the presence of designated or proposed critical habitat within the footprint of these federal actions in support of USFS and Cooperative Agency review of these activities under NEPA.

This report summarizes the meteorological, upper-air (SoDAR¹), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), ozone (O₃), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona, for the third quarter, July 1 through September 30, 2017.

Fourteen sites were studied to provide baseline technical hydrologic monitoring in the Oak Flat area within or adjacent to the projected disturbance zone of the proposed RC block cave mine.

This report summarizes the meteorological, upper-air (SoDAR¹), nitrogen dioxide (NO₂), sulfur dioxide (SO₂), ozone (O₃), and particulate matter (PM) data collected at the Resolution Copper Project near Superior, Arizona, for the second quarter, April 1 through June 30, 2017.

This catalog has been prepared to summarize available information for selected springs and seeps in the Upper Queen Creek and Devils Canyon watersheds. The springs and seeps included in this catalog were selected based on proximity to planned facilities as proposed by Resolution Copper for the Resolution mine project. Version 1.0.

Computed flood flow frequency and volume‐duration‐frequency values for points of interest on Queen Creek and Devil’s Canyon.

The purpose of this traffic study is to evaluate the current and future transportation system at the proposed Resolution Copper Mine expansion without and with the project. Traffic operations were analyzed at existing, key intersections located near the proposed mining operations and facilities during construction and final operations. Revised April 13, 2017.

The purpose of this study is to quantify climbing resources and to assess potential losses for the Environmental Impact Statement (EIS) and to help identify needs for potential mitigation. Aside from a climbing resources inventory, this memorandum also provides background information related to climbing resources, including a description of areas within the Queen Creek climbing area.
