Large and bulky wastes are separated to prevent bridging of the surrounding refuse. These items <br />are placed in the lower portion of the advancing lift, and crushed by compacting equipment. <br />Temporary soil berms are constructed where needed to intercept and divert surface runoff water <br />away from the working face. <br />6.4 COVER <br />6.4.1 Cover Materials <br />Daily and intermediate cover is provided from soil excavated from the area of the next planned <br />Area or from the stockpile on site (Plate 2 and Appendix K). Imported soil is not used at this time. <br />Soil cover is placed with the use of scrapers or other appropriate equipment. Scrapers haul soil <br />from the borrow area to the working face at the end of a workday to cover refuse not covered by <br />synthetic tarps. If there is an increased workload, soil may be stockpiled for use early in the <br />morning. Other equipment may be used as needed. <br />Is Although the scrapers may directly cover the waste with the soil, dozers are also used to spread <br />the soil over the waste. Other equipment may be used. <br />v <br />Soil is moved directly from the borrow area to the working face in dry weather. Preparations for <br />wet weather include placing a soil stockpile near the active face, thereby minimizing travel <br />distance over muddy surfaces. <br />Treated wood waste is stored in a covered bin until disposal in the landfill. <br />6.4.2 Daily Cover <br />Waste is covered with a minimum six inches of compacted soil or tarps as alternate daily cover <br />(ADC) at the end of each operating day to control vectors, fires, odor, blowing litter, and <br />scavenging. <br />North County RC&SL Page 40 of 68 Public Works/Solid Waste <br />Joint Technical Document County of San Joaquin — October 10, 2014 <br />
