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 22, 2011. The site drainage remains in <br /> excellent condition due to the drainage improvements made during the Site Improvement Project in 2006 <br /> (Photo 1) and due to continuing work by the site operator during the year. Similar to last year, the landfill <br /> operator covers recently constructed side-slopes with gravelly topsoil scraped from surrounding areas. The <br /> gravel and cobbles in the soil provides protection against erosion while the seed in the soil sprouts. <br /> Drainage downcomer inlets were free of obstructions. <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 /> Disruptions of drainage features, when needed for temporary access to areas of the landfill not otherwise <br /> accessible, were repaired (Photo 2). <br /> This year the site was again grazed by sheep (Photo 3). The primary intent of grazing is to maximize <br /> visibility of rodents to hawks and other raptors, thereby reducing rodent population. <br /> If you have any questions, please call me at(209) 468-8504. <br /> Sincerely, <br /> W.
