Permitting & Compliance

Precious Metal Mine Reclamation and Closure

San Luis, Colorado

Precious Metal Mine Reclamation and ClosureEngineering Analytics, Inc. is assisting Battle Mountain Resources, a subsidiary of Newmont, with the surface land reclamation and closure of their mining facility located in Costilla County, Colorado. Current reclamation and closure activities consist of completing remaining surface reclamation of mining and milling disturbance, extracting and treating groundwater from the backfilled pits, and assisting with monitoring surface and groundwater within the permit area. EA’s design and closure services at this site include permitting assistance, development of reclamation plans for the lined tailing facility, spillway design, stormwater and diversion ditch design, groundwater and subsurface investigation, modeling, and groundwater treatment. Permitting and compliance activities include regulatory interface, reporting, permitting requirements, development of safety and emergency response plans. Additionally, EA provides process design, instrumentation and controls, electrical, groundwater characterization, and sampling assistance services for the groundwater treatment system.


Aquifer Protection Permits

Aquifer Protection PermitsSan Manuel Smelter / Mine Site and Pinto Valley Mine, Arizona

Engineering Analytics staff prepared Aquifer Protection Permits (APPs) to demonstrate that the facilities incorporated the Best Available Demonstrated Control Technology (BADCT) into their operations. The permits involved intensive investigation of potential discharge points at the site including valves, pipelines, tanks, pits, and the mines themselves to either document compliance or design required control technologies that could be implemented in a reasonable period of time.

Adaptive Management Plan Water Use License

Victoria Gold Corporation, Eagle Gold Project, Yukon, Canada

Engineering Analytics assisted in developing the Adaptive Management Plan (AMP) for submission in the Water Use License for this proposed open pit, heap leach gold mine. The purpose of the AMP was to develop a response framework describing what action Victoria Gold will take in response to aquatic monitoring results reaching pre-defined “action” levels.
