Dirt, oil, and debris that collect in parking lots and paved areas can be washed into the storm sewer system and enter local waterbodies. Sweep up litter and debris from sidewalks, driveways and parking lots, especially around storm drains. Cover grease storage and dumpsters and keep them clean to avoid leaks. Do not wash off floors or decks, kitchen equipment, or dump mop buckets or other chemicals onto paved surfaces as this contaminated water is washed into the storm sewer system and enters local waterbodies
