Specific Relevant Experience


Pikes Peak – America’s Mountain, Erosion and Sediment Control Facilities, Colorado.  Project manager and engineer of record for design and construction of erosion and sediment control facilities in seven priority basins.  The design and construction included 39 sediment control structures comprised of 9 sediment ponds, 26 riprap weir sediment detention ponds, and 4 rock check dams.  Dr. Kunkel is the engineer of record for this project.

Summitville Mine Superfund Site, Colorado.  Project manager and engineer of record for design and construction of water management structures and improvements.  The facilities included a sediment/water detention pond to control water and sediment discharge from the mine highwall.


Big Springs Heap Leach Pad and Tailing Storage Facility Closure, Nevada, USA.  A series reclamation cover options were assessed for the closure and reclamation of the heap leach pad and tailing storage facilities at the mine.  The U.S. EPA HELP model was used to design the pad and tailing storage facility covers.  SedCAD was used to design both a short-term and long-term water and sediment control plan, which included BMPs.

Yanacocha Mine, Peru. Site-wide water, erosion, and sediment control designs for the Yanacocha mine complex, Perú at elevation of 4,000 masl.  The project involved over 10 km of heavy-duty roadway, design of water and sediment control structures using CDOT-recommended BMPs.  Construction drawings and structure details were provided.


San Cristóbal Mine, Bolivia. Sediment control designs for the San Cristóbal mine complex, Bolivia at elevation 3,800 masl.  The project involved over 5 km of heavy-duty access roadway, design of water and sediment control structures using CDOT-recommended BMPs.  Construction drawings and structure details were provided.


Various Copper Mines in USA and Peru. Theoretical and practical laboratory testing and modeling of air and lixiviant flow in large heap leach pads. Direction of laboratory testing and interpretation of laboratory results for air and lixiviant movement. Heap leach pad operational recommendations and published technical papers on two-phase flow in heaps.


Various ESIAs for Gold Mines in Colombia. Environmental manager for one large-scale and one small-scale gold mine projects in Colombia, and participation in two other large- and small-scale gold mine permitting efforts.


Mirador Mine, Ecuador. Environmental management system (EMS) audits for data collection, processing, and reporting for a large copper mine in Ecuador.  Results of the EMS audit resulted in a commitment to utilize a computer program to store, analyze, and report data for environmental purposes. Changes in the methods used to collect environmental data also resulted.
