Did you know that it is illegal to discharge pollutants from automobiles – motor oil, antifreeze, transmission fluid, etc. — into the storm drain? ❌ That’s because automotive fluids are hazardous waste. ⚠ When those pollutants hit the ground, they must be cleaned immediately to prevent them from entering the storm drain system. πŸ’¦πŸ’§ Discharges can happen through spills, leaking vehicles or even rain and overirrigation. Help reduce pollution and improve water quality by taking these simple steps: βœ” Protect the ground from potential fluid spills by using drip pans, drop cloths or absorbent mats. βœ”Use a funnel when changing automotive fluids. βœ”Collect used automotive fluids and materials in sealable containers and properly dispose of them.. βœ” Use dry cleanup methods such as rags, a vacuum or absorbents (cat litter, sand, etc.) to soak up liquid spills. πŸ‘‰ Learn more at bit.ly/ThinkBlue-AutoFluids. . . . #ThinkBlueSanDiego #SanDiego #StormwaterPollution #StormwaterMaintenance #StormwaterBMPs #AutoFluids #PreventPollution #WaterPollution

Hot summer days call for the AC! β˜€ But did you know? Air conditioning condensate has been identified as a source and transport of pollutants hazardous to residents and contributes to ocean pollution. 🌊 If your AC is on, be sure to follow these best management practices: πŸ‘‡ βœ” Direct air conditioning condensation to on-site landscaping to be absorbed by the soil without runoff or erosion. βœ” Direct air conditioning condensate to the sanitary sewer through a direct connection or via a bucket. . . . #ThinkBlueSanDiego #SanDiego #StormwaterPollution #WaterPollution #SanDiegoSummer #StormwaterCompliance #AirConditioning

πŸ“’ The @CityofSanDiego recently updated signage in the Allied Gardens community to reflect new parking restrictions during posted street sweeping times. 🧹 Street sweepers prevent pollutants from flowing untreated into our waterways via the storm drain system. Please help us ensure the sweepers can access the street gutter where pollutants accumulate by doing your part and keeping your vehicle off the street during restricted times. πŸ’¦πŸ’§ There will be a 30-day grace period for parking restrictions ❗ For more information about street sweeping changes: πŸ”— ThinkBlue.org πŸ“ž 619-527-3482 πŸ“§ swppp@sandiego.gov πŸ“° Subscribe to our newsletter at ThinkBlue.org . . . #ThinkBlueSanDiego #SanDiego #StreetSweeping #StormwaterMaintenance #AlliedGardens
