I've had a neighbor doing this &*%$ for well over a friggin'
year!
Some dude with an older RangeRover kept leaking oil, both on the street and in the alley that are only 8 blocks from the Bay.
February 2021, I made him aware that he was leaking oil that ends up in the Bay. He replied (mock-shock) he will get it repaired.
Months passed and his car kept leaking oil and rare rains drained it directly to the Bay.
June 2021, I asked his HOA to do something about it. They pretended they were concerned.
August 2021, I left a phone message to the local City Hall about the continual oil leak. Answering machine musta caught the Covid and died.
September 2021, I contacted the local FD/PD. They were "understanding"!
October 2021, I contacted SurfRiderFoundation. They asked me for a "donation".
November 2021, In a foolish move, I contacted the Coastal Commission. They only deal with spills that are measured in barrels.
December 2021, I got in his face (w/social distancing) about his oil spill. He looked me directly in eye and BS'd me that it was" just a water leak"
What else can someone do?
January 2022, I got my mate to post some photos of dude's RR oil-patches around the neighborhood @NextDoor.com
March 2022, he be not leakin' no moh! Me
... while I drive around in a 6.0Liter ICE...
