Is it true that his business regularly dumps used motor oil in a hole they dug on the back of the property? Does his shop allow motor oil or other chemicals known to the state of california to cause cancer to get into the gutters or storm sewer when it rains?

If that turned out to be true true, the EPA would have lots of fun with his rear end. all it would take is a phone call. They do not blow off things like that, they live for it. Same with the coast guard and dept of fish and game due to the close distance to a large body of water.
BTW of the above mentioned regulatory agencies I have found from personal experience that the department of fish and game is the most aggressive. These guys show up in full uniform with loaded side arms and are authorized and eager to make criminal arrests on the spot for serious infractions.
of all the bad things that can happen to a small business that is one of the worst, no way to recover losses from an insurance company if you get busted for environmental laws.
I'm not suggesting doing anything illegal or fraudulent, just basically posing a hypothetical question............... might take a little investigative reporting.
