P.O. Box 2009 rayl q. Stockton, CA 95201 , RE: Integrated Waste Management Board Letter of 30 November 1990 Austin Road Landfill, Stockton, California As per our recent telephone conversation we are forwarding to you documents that will hopefully shed some light on the controversy that has arisen about the practice of returning Landfill Gas condensate back to the landfill where the gas originated. Figure 1 shows the typical landfill construction at the Austin Road Landfill. Figure 3 shows the trap that formerly was the disposal for the condensate from the plant. Figure 4 shows the present leach line, located less than 2 feet under the surface, the method of disposal that has been in service approximately 2 years now. Figure 5 shows the general location of the leach line in the landfill. As you can see, the condensate has a great deal of refuse to percolate through before it would reach native soil. In response to your request we have included a summary of the laboratory tests of the condensate that we have submitted to the State Water Quality Board in our reporting program to them as well a copy of the recent flow rates. The continued operation of the plant provides several benefits to the City and the County: - Reduction of Landfill Gas surface emissions. - Reduction of Landfill Gas odors and lateral migration into surrounding areas. - Destruction of Methane and other compounds that are considered harmful to the environment. - Property taxes paid on otherwise undevelopable property.
