All oil spills cause environmental damage, regardless of size. Oil is toxic to the environment and the damage starts as soon as the oil enters water. A single quart of oil has the potential to foul more than 100,000 gallons of water.
Prompt reporting of oil spills is important because the sooner responders are notified, the sooner they can work to remove this toxic pollutant from the environment. Oil spills can be reported to 1-800-OILS-911.
