Table 3Summary of Best Management Practices Material Processing & Maintenance
BMP‐1 General Best Management Practices Conduct Regular Inspections of Property; Maintain spill response plans and stocked spill kits in areas where spills are likely to occur
BMP‐2 Reduce waste exposure to stormwater Confine working face of landfill to smallest extents possible and provide daily cover to minimize exposure to stormwater
BMP‐3 Maintain Equipment Perform preventive maintenance; clean equipment surfaces
Storage
BMP‐4 Confine Storage to Designated Areas Stored under cover (where possible) with secondary containment and a spill kit located nearby.
