Headquarters $9M design/build project for the Department of Energy for the closure of a municipal landfill, including airport improvements at the Los Alamos County Airport. The project consisted of the development of all design documents, specifications, and plans to implement the design and construction of the landfill cover in accordance with applicable RCRA Subtitle C requirements in close coordination with Los Alamos County and the FAA. Construction included removal and redistribution of over 400,000 cubic yards of waste (primarily from the steep eastern slope in Pueblo Canyon), construction of a methane gas collection system, construction of concrete retaining wall and mechanically stabilized earthen (MSE) walls to ensure the stability of the eastern 3:1 slope, construction of five concrete airplane hangar pads and tie-downs for airplanes, construction of a MatConŽ asphalt surface over the waste; and completion of a complex storm water control system that directed water away from the landfill cover. This project was completed under the Voluntary Consent Order with the State of New Mexico and North Wind completed the project within the enforceable milestone schedule.
Assessment of 77 EPA Class V Underground Injection Control (UIC) locations (48 dry wells and 29 septic systems) at seven U.S. Army facilities throughout the state of Alaska to determine whether contaminants were introduced into the subsurface through dry wells and septic system leach fields.
Remediation of RCRA hazardous waste sites at the Tooele Army and Deseret Chemical Depots, UT. Work included excavation, sampling, on-site management, transportation, and off-site treatment and disposal for soil sites contaminated with polynuclear aromatic hydrocarbons, volatile organic compounds, and metals.
Installation, start-up, and operation, maintenance, and monitoring of four air sparging / soil vapor extraction (AS/SVE) remediation systems comprised of 440 AS and 110 SVE wells on this $6M project at Fort Wainwright, Alaska. Contaminants included benzene, tetrachlorethene, trichloroethene, gasoline range organics, diesel range organics, and volatile organic compounds.
