Proper preparation will mean that I precipitation falling on the landfill flows away from the working face, or is impeded from reaching the face. This reduces the chance for water/refuse contact and helps keep the working face and surrounding area as dry as possible. Berms, ditches and/or sandbags placed up-slope from the working face can be used to divert water to the storm sewer system or to infiltration ponds. Excessive rainfall will affect drainage and daily/intermediate cover materials differently. Generally, it is best to wait for drier weather conditions prior to handling sand used in a drainage blanket in order to avoid contamination by fines. Cover soils should be compacted and sloped after placement to carry water to a lower elevation and prevent ponds from collecting over the refuse. The landfill operator may choose to cover stockpiled soils with a flexible membrane liner (FML) to prevent erosion due to excess water runoff during excessive and/or prolonged rainfall. The FML should be secured with sandbags or similar items to prevent it from blowing away. With the creek realignment, some areas around the circumference of the landfill and adjacent to the creek are designated as flood plain areas, and the operator should recognize that flooding may occur in these areas during periods of excessive rainfall. These potential flooding areas are _. shown on the final grading The Waste Discharge Requirements for the Austin Road Landfill requires the following: n Surface drainage from tributary areas and internal site drainage from surface or subsurface sources shall not contact or percolate through wastes. a Annually, prior to the anticipated rainy season, any necessary erosion control measures shall be implemented, and any necessary construction, maintenance, or repairs of City o`Stockton R.W.Beck and Associates 1811.002
