Mining Project Profiles
Permitting & Compliance
Environmental Impact Statement (EIS)
Red Dog Mine, Alaska
Engineering Analytics staff performed stream sediment and water sampling under winter conditions downstream of the Red Dog Mine in northwestern Alaska. Water sampling in concert with sequential sediment extraction techniques and geochemical modeling was employed to characterize the downstream partitioning of metals between the surface water and stream sediments. Work was performed in support of the NPDES permit renewal process under the EIS.
Aquifer Protection Permits
San 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.
Air Dispersion Modeling
Haile Gold Mine, South Carolina
Engineering Analytics completed the air quality permitting section of the Environmental Impact Statement for the mine. The scope of work included performing emissions calculations and completing the air quality permit construction application. AERMOD dispersion modeling was completed to determine potential criteria pollutant concentrations.
Groundwater Flow Modeling
Kearl Oil Sands Project, Alberta, Canada
Engineering Analytics staff developed a three-dimensional (MODFLOW/SURFACT) flow model to estimate the de-watering requirements for an open pit oil sands mine. The proposed mine is located approximately 70 km north of Fort McMurray in Alberta, Canada. Mine de-watering well fields were designed and simulated to ensure mine de-watering while not impacting neighboring mines. Tailings pond construction, filling, and subsequent reclamation were simulated over the 50-year life of mine.
