Response to LEA Inspection, 2-24-05 April 6, 2005 Page 2 of 3 6. The green waste feed stockpile is routinely inspected and excessive contaminants are removed prior to processing. 7. Additional intermediate cover was placed on the west slope of the old Forward Landfill on March 11, 2005, covering any exposed waste in that area. 8. The problem of leachate seeps from the old Austin Road Landfill was documented many times while this area was under the control of the City of Stockton. Due to the excessive rainfall this winter, this problem has reoccurred. We are working with our consulting engineers and the California Regional Water Quality Control Board to develop a plan for a partial final closure plan in order to construct a final cover layer over this area to prevent future occurrences. It is our intention to present a draft plan to the RWQCB early this summer and to complete the construction prior to next winter. However, we disagree with the finding that this situation is a violation of Title 27 20790, which reads "The operator shall ensure that leachate is controlled to prevent contact with the public." The leachate seeps are on the northern slope of the old Austin Road Landfill and south of the relocated Littlejohn's Creek. This area is controlled from public access by both the creek and the landfill fence. The leachate is contained from reaching the creek by a perimeter drainage channel approximately twenty feet from the toe of the landfill slope. As necessary, the leachate is removed from the drainage channel by means of a pump and transported to the onsite leachate evaporation pond for disposal. The access control and containment features are adequate to prevent the public from contact with the leachate. We request that this item be amended to an "Area of Concern"and tracked on future inspections until weather conditions allow for a temporary correction pending the completion of the partial closure. 9. The landfill staff has marked these areas of minor erosion and as soon as weather conditions allow, proper repairs will be completed. 10. In addition to placing more speed limit signs, the landfill staff has installed a relocatable speed bump system near the landfill exit in order to evaluate the durability of the speed bump components. If this system proves durable, it may be installed in additional locations as needed to control vehicle traffic. 11. The compliance schedule listed in Notice and Order 03-01 is being followed. 12. This well will be addressed as part of the partial closure plan proposed for the northern slope of the old Austin Road Landfill. 13. The landfill gas collection header around the perimeter of the landfill has been inspected and any potential areas where blockage could occur have been reported to our contractor for the landfill gas collection system and will be corrected by April 30, 2005. 14. The partial closure plan for the northern slope of the old Austin Road Landfill will also address the area on the west side of the landfill where the reconstructed creek has overflowed its bank.
