This paper discusses reasons including seepage, foundation failure, overtopping, and earthquake for tailings dam failures and explores failure mechanisms by referring to the available literature.

This letter is in response to questions posed by BGC Engineering "Assessment of Surface Faulting Investigations at the Skunk Camp TSF Location".

Large spreading shrub or small tree up to 8 m (26.25 ft) tall, but more often 1- 4 m (3.28-13.12 ft) tall, with roughish, dark gray bark and densely stellate-pubescent twigs.

This Final Environmental Impact Statement (EIS) analyzes impacts that may occur from a proposed land exchange combined with a proposed plan amendment.

During the Water Working Group Meeting held on June 25, 2020, there was a request for more details about how nitrogen (N) chemical loads and concentrations were estimated in the block cave geochemistry and tailings solute models. The purpose of this memo is to provide these details and to serve as clarification to action item WR-20.

The purpose of this process memorandum is to provide the background and summary of the total direct and indirect emissions of greenhouse gases (GHG) associated with the proposed action for the Resolution Copper Mine (RCM) Development near Superior, Arizona.

The management plans serve as a tool to assist the Arizona Department of Water Resources in achieving the groundwater goals of each of the state's five Active Management Areas.

This plan contains the conservation programs that are intended to guide the Phoenix AMA to meet it management goal - and these conservation programs are to be designed to achieve reductions in groundwater withdrawals.

The process of updating the Pinal model geology was begun in 2007, and had not been addressed since Modeling Report No. 2 (Corkhill and Hill, 1990). The purpose of this provisional report is to document the data collection activities and findings of the hydrogeologic framework of the study area. This report will be finalized after the Pinal Active Management Area (AMA) Regional Groundwater Flow Model report which documents the update and recalibration of the groundwater flow model in Pinal County have been completed.
