California has a water runoff law. Any industrial or commercial activity has to be completely covered to prevent contamination of the runoff water. Anyone operating an industrial or commercial enterprise is subject to this law. You have to file with the state every year showing the slope of your property and where water runs, and subject to inspection. We had no issues at our place of work but of course an inspector isn’t doing his job if he doesn’t find something to write up. So he told us to install an industrial sponge by the door “just in case” there is some kind of spillage that may potentially leak out into the driveway.
Cars are exempt, but if you do any work outdoors or in the parking lots or back lots or store anything outdoors you have to show how it won’t cause contaminant to run off into the sewers. I wonder if municipalities and states are exempt?
This sounds like a great plan—until a bribe is paid and accepted.. ;-)
