Completion Date: August 2000
Description: In order to register a former K-Mart Store that was built atop a closed municipal landfill with the TCEQ, Enviro-Tech conducted a comprehensive subsurface investigation of the nine-acre site by installing soil borings across the entire property on fifty-foot centers, including interior of building. Each boring was screened for the presence of methane gas with a portable flammable gas detection unit, and the depth of the landfill cover material and depth to the landfill were also measured and recorded.
Based upon the results of the investigation, a passive methane venting system was designed and constructed within the footprint of the existing building, and a total of thirty-two portable ?real time? methane gas detection units were installed at various locations within the building as part of the registration process. Enviro-Tech then checked methane gas levels in the building on a quarterly basis for a period of one year as part of the permit application.
