What about washing my car in the driveway?

When washing your vehicles or other equipment, use environmentally safe soaps. Keep the wash water and rinse water on the grass as much as possible. To reduce the impacts of runoff on urban streams, EPA expanded the Clean Water Act in 1987 to require municipalities to obtain permits for discharges of stormwater runoff. As a result, many communities have adopted regulations requiring developers to install stormwater management practices that reduce the rate and/or volume and remove pollutants from runoff generated on their development sites.
