North County Recycling Center and Sanitary Landfill <br />Storm Water Pollution Prevention Plan <br /> <br /> <br /> <br />Page 47 <br />Area Activities Pollutant <br />Sources <br />Potential <br />Pollutants <br />Best Management Practices <br />Landfill • Receiving and burying of non- <br />hazardous landfill wastes <br />• Earthwork <br />• Operation of heavy equipment <br />• Operation of the landfill gas collection <br />and flare system <br />• Operation of the landfill leachate <br />collection and treatment system <br />• Wind-blown or <br />tracked-out <br />sediment <br />• Fugitive trash and <br />debris that is <br />blown, spilled, or <br />tracked from the <br />landfill module <br />• Fugitive dust <br />• Non-storm water <br />from dust control <br />water or spills <br />from disposal <br />activities <br />• Oil and grease <br />from vehicles <br />• Organic enrichment <br />from green waste and <br />trash manifested as <br />elevated BOD <br />• Sediment <br />• Heavy metals including <br />copper, iron, mercury, <br />and zinc <br />• Pathogens <br />• Oil & grease <br />• Hydrocarbons <br />• Nutrients <br />• Pesticides <br />• Other potential toxics <br /> <br />• A local retention basin is used to provide <br />primary settling of solids. <br />• Storm water from the local retention basin is <br />pumped to the Interim Sedimentation Basin <br />(ISB) where solids can settle out. <br />• Temporary wind screens are used to capture <br />fugitive trash <br />• Water trucks are used to prevent wind erosion <br />• Track out controls have been installed at the <br />exit of the active landfill module <br />• County crews regularly canvas the surrounding <br />areas and the perimeter of the facility to pick-up <br />fugitive trash <br />• Erosion and sediment controls are used for the <br />conveyance of storm water and the stabilization <br />of completed slopes and modules <br />• Surrounding roadways are inspected daily and <br />swept as necessary. <br />• Areas of active landfilling are covered at the <br />end of each day with “daily cover” to prevent <br />wind-blown trash, scavenging, vector problems, <br />emissions, and storm water pollution. <br />• Various permeable surfaces utilize crushed rock <br />to assist with erosion control. <br />• Storm water conveyances swales immediately <br />up-gradient of the outfalls utilize both standard <br />compost filtering socks and compost filtering <br />socks with a metal absorbing additive for check <br />dams and Sediment Traps. <br />• Storm water conveyances swales contain check <br />dams for erosion and sediment control. <br />• West storm water conveyance swale redesigned <br />to detain runoff.
