C <br />C <br />Soil is placed with the use of scrapers. Scrapers haul soil from the borrow area to the working <br />face. Although the scrapers may directly cover the waste with the soil, typically dozers are used <br />to spread the soil over the waste. Once the waste is covered with soil a compactor then compacts <br />the soil. Soil is moved directly from the borrow area to the working face with the exception of <br />the winter months when soil is generally stockpiled near the working face. Scrapers typically <br />move soils to the working face at the end of the workday. If there is an increased workload, soil <br />may be stockpiled for use early in the morning. <br />7.2.2. Daily Cover Frequency <br />Currently, waste is covered with a minimum thickness of 6 inches of compacted soil cover at the <br />end of each operating day to control vectors, fires, odor, blowing litter, and scavenging. In the <br />future, alternative daily cover (ADC) may be used after submittal and approval of an addendum <br />to this JTD allowing ADC. <br />7.2.3. Intermediate Cover Placement <br />Intermediate cover consisting of at least 12 inches of soil will be placed on the surfaces of the fill <br />where no additional refuse will be placed within 180 days to control vectors, fires, odors, <br />blowing litter, and scavenging. Intermediate cover is placed as described above in Section 7.2.1. <br />7.2.4. Partial Cover Placement <br />Surfaces that have reached final elevations or which are not at final elevations but which will not <br />receive refuse within two years much be provided with "Partial Cover" in accordance with the <br />WDRs. Partial Cover requires the following soil thickness: <br />• Slopes 5:1 and less: a total 3 feet of compacted soil <br />• Slopes steeper than 5:1: a total of 2 feet of compacted soil <br />Foothill Sanitary Landfill <br />JTD <br />Page 49 of 62 Public Works/Solid Waste <br />County of San Joaquin — Revised 10/6/05 <br />
