The proposed project would not result in significant habitat alteration, effects outside the project area, cumulative effects on listed species or habitat, or cumulative effects on sensitive species or habitat.

Guidance for Federal departments and agencies on establishing, implementing, and monitoring mitigation commitments identified and analyzed in Environmental Assessments, Environmental Impact Statements, and adopted in the final decision documents.

There is no evidence to suggest that there is any mechanism in the Resolution process circuit likely to result in technologically enhanced naturally occurring radioactive material (TENORM) in tailings, concentrate, or process water.

These guidelines represent the culmination of efforts, initiated by President Carter in April 1977, to review procedures and criteria used by Federal Agencies involved in the design, construction, operation, and regulation of dams and to prepare guidelines for management procedures to ensure dam safety.

Minutes for meeting with goals to review results of modeling conducted by RCM for the Desert Wellfield pumping in the East Salt River Valley and discuss permitting pathway.

This Field Summary Report describes the investigation tasks and activities associated with the Near West Tailings Storage (TSF) geotechnical investigation. The objectives of the investigation were to obtain data necessary to support the pre-feasibility design of the proposed Near West TSF, to obtain additional information to support hydrogeological characterization of the site, and to characterize potential borrow materials located near the TSF footprint.

Mature desert pavements are traditionally regarded as hallmarks of stability, but their stability is dynamic, not static

The International Council on Mining & Metals (ICMM) today announced its governing Council of 27 member CEOs will establish an independent panel of experts to develop an international standard for tailings facilities for its member companies.

This letter provides the potential range of uncaptured seepage with discussion on uncertainties for the Alternative 4 Silver King Filtered TSF.

The main objective of this study is to incorporate the additional data in the existing model representation and refine the existing ADEQ dissolved copper model calibrations in the Queen Creek watershed.
