(a) Even small spills can have cumulative effects that add up to a significant source of potential pollutants in storm water discharges from the site. The goal is to prevent spills and leaks, maintain a regular inspection and repair schedule, and correct potential spill situations before a spill can occur.
(b) When a spill does occur, quick and effective response will prevent pollutants from reaching storm water. Spills will be cleaned up promptly and not allowed to evaporate so that pollutants do not remain on the pavement to be washed to the storm drains with the next rain or remain in the soil to become a possible groundwater pollutant. If the spill is on an unpaved surface, personnel will determine whether the contaminated soil should be removed to prevent it from being a source of future storm water pollutants. Spill procedures will also include cleaning up leaks, drips, and other spills without water whenever possible.
(c) Spill prevention and response procedures for hazardous materials stored or handled onsite will follow the procedures described in the facility Hazardous Materials Management Plan. Properly trained personnel will contain and collect the spilled substance then dispose of the substances and any contaminated soil in compliance with local hazardous materials regulations.
(d) The spill control and cleanup procedures for this facility are as follows:
(1) Small spills: These are spills that can be wiped up with a shop rag. Wet rags will not be put in the dumpster with the shop trash - they will be stored in a covered bin like the kind used at auto service stations. Used rags will be sent to a professional cleaning service or disposed of with the hazardous wastes if necessary.
(2) Medium-sized spills: These are spills too large to wipe up with a rag. Medium sized spills will be contained and soaked up using dry absorbent material such as:
Vermiculite, specially-prepared sawdust, or kitty litter. Absorbent snakes may be used as temporary booms to contain and soak up the liquid. Used absorbent material will be swept up or collected and will be disposed of with the shop trash if non-hazardous or with the hazardous wastes if necessary. A wet/dry shop vacuum cleaner may also be used to collect spills and dispose of the liquid with hazardous wastes. Vacuums will not be used for gasoline, solvents, or other volatile fluids, because the enclosed vacuum may become an explosive hazard.
(3) Large spills: Spills of non-hazardous liquids will be contained and cleaned using a minimum amount of wash water. Storm drain inlets or sewer inlets will be plugged to prevent the spill enter from entering the MS4. Temporary plugs will be kept onsite for the facility inlets and employees will be trained in when and how to use them. For hazardous materials spills, the procedures described in the Hazardous Materials Management Plan will be implemented.
(e) A Spill/Release Incident Reporting form is provided in Appendix A. This form should be filled out promptly after a spill or release.
