0 6.8.2 Leachate Control <br />Generation of leachate is limited by controlling the intrusion of water into refuse. The County <br />uses daily cover, constructs the landfill surfaces with slope to drain, and places berms in the <br />active area to divert storm water away from the active area so that it does not come into contact <br />with the waste. <br />Leachate is returned to the landfill over Subtitle D -lined areas (Areas 3 and future Areas) in <br />accordance with the current Waste Discharge Requirements. <br />6.8.3 Dust Control <br />Dust is controlled at the landfill by watering of haul roads and tipping areas as needed. In <br />addition, paved roads are washed with a water truck weekly or as needed. Haul roads and the fill <br />area are watered if there is visible dust. Water is applied by water trucks with sprinklers on the <br />front and back. Frequency of water application is dependent upon the season and site <br />conditions. The most frequent application will occur during the summer in windy conditions. The <br />performance standard of "controlling visible dust" dictates the frequency of water application. A <br />log of water truck loads is kept with time and location of watering at the landfill. <br />Dust within the Recycling Center is controlled by the use of an overhead sprinkler system. <br />6.8.4 Vector and Bird Control <br />Waste is properly covered daily with either soil or a tarp to control vectors. In addition, site <br />personnel inspect the site for signs of vector activity. If such activity is observed, a vector <br />eradication program is implemented using a professional pest controller, if necessary. If needed, <br />bait for rats or squirrels, may be placed. California Pest Control is called for pest control for <br />rodents in the buildings approximately once per month. Birds, primarily seagulls are disbursed <br />from the active face by propane -fueled noise cannons. Each day from October to April a County <br />contractor disburses the birds using hawk rockets, "bird bombs", and a radio -controlled airplane. <br />North County RUSL Page 46 of 68 Public Works/Solid Waste <br />Joint Technical Document County of San Joaquin — October 10, 2014 <br />
