O. BOX 1810 - 1810 E. HAZELTON AVENUE <br />STOCKTON, CALIFORNIA 95201 <br />(209) 468-3000 FAX (209) 468-2999 <br />www.sjgov.org/pubworks <br />SUBJECT: ANNUAL 2010 FACILITY INSPECTION, FOOTHILL SANITARY LANDFILL <br />Dear Mr. Del Frate: 1 <br />Please consider this the report of the Annual Facility Inspection, in accordance with Section 5a of the <br />Monitoring and Reporting Program for the Foothill Sanitary Landfill. The Standard Observations report is <br />also included, as required by Section 5a. <br />The site was inspected by Solid Waste Division staff on September 13, 2010. The site drainage remains in <br />excellent condition due to the drainage improvements made during the Site Improvement Project in 2006 <br />which provided consistent vegetative cover (Photo 1) and due to continuing work by the site operator during <br />the year. Similar to last year, the landfill operator covers recently constructed side -slopes with gravelly <br />topsoil scraped from surrounding areas. The gravel and cobbles in the soil provides protection against <br />erosion while the seed in the soil sprouts. Drainage downcomer inlets were free of obstructions. <br />This year the site was grazed by sheep (Photo 2). New growth was visible in the grazed areas after the <br />early rains of October (Photo 3). <br />The active face and working area of the landfill is sloped to drain south into the borrow area where most or <br />all water will infiltrate. Drainage from the remainder of the landfill surface is directed to the infiltration pond <br />east of Module "I". Some drainage improvements are ongoing, coinciding with ongoing refuse fill. <br />I believe these conclusions agree with the observations by our Local Enforcement Agent in October. <br />If you have any questions, please call ae at (209) 468-8504. <br />Sincerely, <br />W.
