RECONSTRUCT SURF ACE LINER: This part of the project would involve removing the existing agricultural layer of soil, screening and stockpiling on site, then smoothing the existing clay liner. A new cap would be installed over the old one using a Geo-synthetic Clay (permeability of 5 x 10 e-9 cm/sec), followed by a VLDPE or equivalent synthetic liner (40 mil thick), and a double bonded geonet layer installed for drainage. At least 24-36 inches of protective cover will be placed over the landfill and grass established. Edge drains may be installed to collect runoff from the geonets, and subsequently directed to the sedimentation basin. Three gas vents will be added to the existing one. II. LINING OF THE SEDIMENTATION BASIN The current sedimentation basin would be cleaned and graded, a Geo-synthetic clay liner and 40 mil VLDPE liner would be installed. A "Fabriform" protective cover would be placed over the plastic liner. The basin would be used to collect water from the landfill and subsequently pumped back over the landfill surface through an irrigation system. III. LEACHATE REMOVAL SYSTEM A leachate removal system will be designed and installed in the two bore-holes established this spring in the landfill and on the existing leachate pumping system. Leachate would be systematically and continuously removed from the landfill, passed through the sand and carbon filter beds and discharged to the sedimentation basin and eventually spray irrigated over the landfill. IV. WASTE WATER PLANT OPERA TOR A certified Waste Water Treatment Plant Operator must be employed by the state to oversee the actual process of removing and treating the water from the landfill. There is a potential to have this position as a "part-time" position once the system is in place and operating via an automatic system. V. EPA COMPLIANCE It is anticipated that EPA will issue a compliance order to the state within the next 60 days, upon their completion of a review of lab data from the recent sampling event. This order will most assuredly include removal of water from the landfill and potentially a requrirement for a new cap, depending on the funding available (or decision by the state) for detoxification. No other funds are available to complete this project.
