Forward Landfill -2- 8 February 1988 violation of Waste Discharge Requirements, Discharge Specification 8.42 which reads "Soil piles, stored in WMU G shall at all times be completely covered with a synthetic liner, except during aeration". I also noted many areas in WMU G with ponded water. The current Waste Discharge Requirements, in Discharge Specification 8.44, require that WMU G be graded so that runoff will collect in a sedimentation pond dedicated to that unit. WMU G will have to be regraded to eliminate ponding and direct runoff to a sedimentation basin. Before we left for lunch, Bob and I walked the perimeter of the site. I saw many instances of erosion damage, most notably on the south and west sides of WMU B. In addition, I noticed numerous animal burrows on the north face of WMU A with areas of localized soil sloughing due to activities of burrowing animals. Burrows of rodents such as ground squirrels can extend back into the berm as far as 30 feet. If not controlled, these burrows can become numerous enough to affect stability of the berm. Erosion and animal burrows are a violation of waste discharge requirements. Discharge Specification B.16 states that "Class II landfill units and related containment structures shall be constructed and maintained to prevent. . ., erosion, slope failure,. . ." After lunch, we returned to the landfill and observed sampling of Monitoring Well No. 6 by a. crew from California. Water Labs. Steve Furnas, owner of the lab, was there monitoring the sampling operation. Water withdrawn from the well contained a. heavy sediment load. While removing their purging pump from the well , the pump hung up on the well screen and the hose and power connections were ripped from the pump. Hopefully, the well screen was not damaged. I collected splits for volatile organics analysis. Since their pump was damaged, the sampling crew had to quit for the day. INSPECTION SUMMARY Ponded water was observed at several locations around the landfill, a. violation of current waste discharge requirements. Improperly bagged infectious waste was found in WMU D. As such, this waste is difficult to detect and the landfill operator will need help from other agencies such as the San Joaquin Local Health District to deal with this problem. Soil stored in WMI1 G was not completely covered, a violation of current waste discharge requirements. WMU G must be regraded before aeration c n begin this spring. WMU 8 has erosion damage, another violation of waste discharge requirements, that needs to be corrected. All of the exterior berms at the site have extensive rodent damage that, if left unchecked, can impair the effectiveness of these structures. f TIMOTHY A. CRANDALL, Project Engineer TAC:j Attachments
