for recovery and subsequent recirculation and/or discharge to evaporation ponds on-site. Monitoring schedules will be established in conformance with State issued Waste.Discharge Requirements. Although hazards relative to migrating landfill gas appear minimal, a limited monitoring program along the western perimeter would be conducted as the site expands to the north where buildings are within 1,000 feet. Monitoring would consist of probes installed to a depth equivalent to the base of the landfill. The bulk of landfill gas should naturally vent into the atmosphere alleviating the need for specific collection methods unless warranted by later monitoring. Although landfill gas recovery is not planned initially, this aspect for recovery of an energy source could be evaluated in the future. Each 20 -acre plot would be excavated to an approximate depth of 30 to 40 feet, with the completed fill standing 0 to 10+ feet above the present level of Harney Lane. Surplus borrow material in excess of site cover require- ments may be exported for other County uses. Surplus borrow would also be used in continued maintenance of graded.fill slopes to maintain uniform sur- face drainage. Temporary and permanent diversion structures would be construc- ted to channel surface runoff away from refuse and into South Paddy Creek. To mitigate potential heavy silt loadings during heavy precipitation, completed fill areas will be revegetated and a sediment basin(s) will be constructed. A minimum compacted soil thickness of six inches would be applied on top of compacted wastes in the trench at the end of each operating day. Final cover is to be applied on each completed trench to a minimum two -foot depth of compacted soil cover. Final cover material would be applied and compacfed in six-inch thick layers. At this time, anticipated site usage after refuse filling is completed is that it will return to agricultural (i.e., grazing or farming) or recreational uses. .Although site life has not been specifically determined for this fill method, it should extend past the year 2000 when approximately 3,200 (seven- day basis) tons of residential and commercial waste per week are expected.
