Causing that condition to exist is probably a felony in CA.
I KNOW that pouring it down a drain is a crime there.
30 years ago my business was in California. Nearby, there was a gas station. These guys
http://www.calepa.ca.gov/ crawled up my backside about three feet - they were chasing a pollution source upstream. They tested every drain on the property, went through my shop and my records. I was clean, but they were on the warpath.
It turned out the garage / gas station had found a "magic pipe" on their property that actually fed the sewer line under my location. They were using it to dispose of all sorts of stuff they were not willing to pay to have picked up.
1) Do NOT create messes like that bucket. If you have drain oil, put it in jugs & recycle it.
2) Do NOT pour messes like that down the drain. Your city has resources to deal with your mistakes:
