Susan A. Wyman, P.E., P.G. • Schwartzwalder Aline. Colorado - Developed an extensive water quality database and prepared time-series plots to evaluate geochemical evolution of surface water, groundwater, and the mine pool. Assisted in equilibrium geochemical modeling. Performed mass balance mixing models to predict mine water chemistry. • SchwarL-walder Mine. Colorado - Designed and conducted a water quality survey to determine electrical conductivity, pH, and temperature along a 1.6-mile reach of Ralston Creek. • Schwartwalder Mine, Colorado - Collected stream samples to investigate water quality above and below Schwartz Trend Crossing on Ralston Creek. • Schwartzwalder Aline, Colorado - Compiled and evaluated mitigation options for groundwater in alluvium and fill. Engineered HDPE pressure piping system for gathering and conveyance of alluvial groundwater to the water treatment plant. Designed HDPE gravity piping system for conveyance of treated water to engineered outfall on Ralston Creek. • Io'an Tuyl Ranch, Colorado - Provided pro bono services to City of Gunnison and Western State College for the water resources evaluation of the Van Tuyl Ranch Management Plan. Provided mentoring and equipment to Western State College students in monitoring well installation, development, and sampling. • Blackfoot Bridge Mine. Idaho - Designed baseline monitoring program for surface water. Conducted quarterly field sampling, evaluated data, and prepared summary reports in support of environmental impact analysis for an open pit phosphate mine, as a 3'd party EIS contractor to the US Bureau of Land Management. . North Rasmussen Ridge :Aline. Idaho - Evaluated potential geochemical impacts to surface water and groundwater from selenium and other constituents related to open pit phosphate mining, as a third party EIS subcontractor. Tasks included the analysis of climatological data, developing pit wall runoff predictions, modeling unsaturated flow through capped backfill using UNSAT-H and HELP3, assisting in the development of a groundwater flow model using Modflow and MT3D to assess the potential migration of COPCs in groundwater, developing spreadsheet analytical models for surface water impact analysis, and preparing the Water Resources Technical Report for the US Bureau of Land Management. • North Rasmussen Ridge Mine. Idaho - Evaluated the site hydrologic systems and regulatory framework and prepared the mine's Surface and Groundwater Monitoring Plan for submission to the Idaho Department of Environmental Quality. • Taylor Ranch Project - Designed and implemented baseline monitoring program for surface water, groundwater, and domestic wells. Developed database of historical and ongoing sampling results for water, 'soil, and air. Technical lead on water resource issues in public hearings and permitting applications for state and county environmental permits. • Lisbon Malley Mine. San Juan County. Utah - Located, designed, drilled, completed, and developed 5 industrial water supply wells capable of producing more than 1,200 gpm (630 MGY). Specified and installed high- capacity pumps and designed piping system for conveying well field water to 200,000 gallon storage tank. • Seminoe Road Pilot Project, Carbon County, Wyoming - Designed, installed. and tested a water treatment system for the removal of iron, manganese and barium at 3 surface water discharge points associated with 18 coal bed methane (CBM) production wells. Designed piping, valves, aeration tanks, filter tanks, and surface water NPDES outfall, including pressurized and gravity-fed segments. Provided recommendations for erosion control at outfalls and in-channel drainage structures. • Kinross Gold K-2 Mine, Washington - Designed a pumping and piping system to convey background mine water inflow from the 1290 level to a near-surface infiltration gallery. Evaluated water quality and potential water treatment requirements. Calculated friction losses and surge pressures, and specified pipe size and pump requirements for pressurized steel pipe system. Designed HDPE gravity piping system from the portal to the infiltration bed. Provided dimensions and specifications for infiltration bed components. • Kinross Gold K-2 Aline and Key Alill Site, Washington - Designed three gravity-fed infiltration systems for above-ground and in situ bioremediation of underdrain water and mine water via denitrification and sulfate reduction. Engineered the infiltration systems, prepared design report, and wrote O&M manual for infiltration bed components. 9150.100630 Page 2 of 6
