When your doing this... Cleaning dumpster areas, loading docks, or any paved surfaces Cleaning up spills Cleaning up hazardous materials (e.g., cleaning products) Cleaning large equipment Handling grease, oils, and meat fat Maintaining cooling towers and refrigeration equipment Landscaping and garden maintenance

...Don't forget to do this! Control litter. Make sure the leasing company maintains and cleans dumpsters regularly; return leaking dumpsters for repair immediately. If you must wash down a dumpster, loading dock or other outdoor surface for health reasons, use dry cleanup methods first, and then rinse, collect water, and discharge to the sink or indoor floor drain. Control the spill, then sweep or clean up with rags and granular absorbents. Dispose absorbents to trash, then mop and collect water, put down mop sink, curbed mop basin, or indoor floor drain. Use procedure above, but send residue and absorbents to a hazardous waste disposal site. Clean indoors or within a bermed outdoor area where cleaning water will not flow to a storm drain. Collect water and dispose to a sink or indoor floor drain. Save for recycling in sealed containers. Never pour into a sink, floor drain, or storm drain. Make sure all discharges go to the sanitary sewer and NOT to the street, storm drain, or creek. Advise your maintenance contractor about storm drain protection. Control erosion. Keep yard waste out of the street and storm drain. Use chemicals sparingly, and never in wet weather.
