North County Recycling Center and Sanitary Landfill Storm Water Pollution Prevention Plan Page 35 Row No. Minimum Permit Requirement Facility-Specific Implementation 7. Prevent disposal of any rinse/wash waters or industrial materials into the storm water conveyance system; Wastewater that is generated at the contained vehicle and equipment wash pad passes through a separator and into a collection sump where it is pumped offsite for proper disposal by an authorized waste hauler. Residual sludge material is disposed of at an appropriate off-site facility. 8. Minimize storm water discharges from non- industrial areas (e.g., storm water flows from employee parking area) that contact industrial areas of the facility; and, The facility’s only non-industrial areas consist of the wetlands located on the north side of the facility and the perimeter on the east, south, and west sides. They drain directly to Paddy Creek. All industrial areas discharge to the Interim Sedimentation Basin. 9. Minimize authorized NSWDs from non- industrial areas (e.g., potable water, fire hydrant testing, etc.) that contact industrial areas of the facility. The only authorized NSWD from the non-industrial wetland areas would be the surfacing and runoff of shallow groundwater. This water would discharge directly into Paddy Creek and not comingle with water from industrial areas. Another possible unauthorized NSWD would be the condensate at the LFG flare. However, this water is normally captured and is re- applied to the landfill modules (except for Module #1). . 8.1.2 Preventive Maintenance In keeping with the permit requirements for preventative maintenance, San Joaquin County implements the following practices: Table 8.1.2 – Preventative Maintenance Measures Row No. Minimum Permit Requirement Facility-Specific Implementation 1. Identify all equipment and systems used outdoors that may spill or leak pollutants; • Landfill modules and module soil cover • Landfill gas flare station • Landfill gas extraction wells and piping • Landfill vehicles and equipment • Fuel aboveground storage tanks • Wood mulch mixer and totes/drums of colorant dye 2. Observe the identified equipment and systems to detect leaks, or identify conditions that may result in the development of leaks; As outlined in the JTD, regular maintenance of the landfill includes the following activities: • Fill ponding and low spot areas noticed during inspection with soil from the borrow area. • Repair any erosion soil covers • Maintain vegetation on the soil covers • Fill holes created by rodents Maintenance at the flare station includes the following activities: • Rotation of active/inactive blowers (monthly). • Lubrication of blower and drive motor bearings (monthly). • Adjustment of the blower belts (as needed). 3. Establish an appropriate schedule for maintenance of identified equipment and systems; and, 4. Establish procedures for prompt maintenance and repair of equipment, and maintenance of systems when conditions exist that may result in the development of spills or leaks.
