Foothill Landfill <br />Storm Water Pollution Prevention Plan <br /> <br /> <br /> <br /> Page 28 <br />Locations <br />Materials or Wastes <br />Produced, Stored, or <br />Used <br />Pollution Prevention <br />Procedures Containment <br />(appliances) and e-waste <br />are segregated in this area <br />and placed into covered <br />bins. Fueling, washing, <br />and maintenance of heavy <br />equipment is performed in <br />this area. <br />x LF-2 has a leachate collection <br />system. Leachate is re-applied <br />onto the refuse of a lined landfill <br />area. <br />x Spill kits are available for spills <br />of oil, fuel, or other vehicular <br />fluids. <br />x LFG condensate from LF-2 is <br />combined with landfill leachate. <br />LFG condensate from LF-1 is <br />removed from the site for <br />disposal elsewhere <br />x Surface runoff flows and/or is <br />pumped to storm water retention <br />basins <br />x Leachate and condensate are <br />contained within the pipes and <br />tanks of the systems or within the <br />refuse itself, and are not exposed to <br />storm water <br /> <br />Landfill Gas to <br />Energy Plant <br />Landfill gas condensate is <br />produced, and lubricants, <br />propylene glycol, and urea <br />are used in the landfill gas- <br />to-energy plant. <br />x Secondary containment for the <br />leachate and oil tanks. <br />x Most electrical generation <br />equipment and processes are <br />within a covered building <br />x Spill kits are available <br />x Good housekeeping procedures <br />are taught <br />x Generally, LFG condensate is <br />returned directly to the landfill from <br />an underground 1,130-gallon tank. <br />Otherwise it is pumped into a <br />10,000-gallon aboveground storage <br />tank located north of the main plant <br />and containment structure. <br />Condensate from LF-2 and leachate <br />can be used for dust suppression <br />on LF-2. <br />x A double-walled 1,000-gallon motor <br />oil and a double walled 1,000-gallon <br />used oil aboveground storage tank. <br />x A 1,000-gallon urea tank used for <br />emissions control is not contained. <br />x Ultimately large enough spills or <br />those mobilized by storm water <br />would flow into the conveyance <br />ditch and into the small retention <br />basin south of the plant where it <br />would be captured and remediated. <br />Soil Borrow <br />Areas <br />Clean soil, fuel for re- <br />fueling heavy equipment <br />x Erosion and sedimentation <br />controls for runoff from the area <br />that include sediment basins, <br />perimeter controls, and erosion <br />controls for inactive areas. <br />x Sediment basins help contain <br />eroded material and fuel spills <br /> <br />
