In the mid '60s (high school) and again in the early '70 (college) I was working summers for petroleum piping contractor.
One of the jobs I recall was cleaning leaded gasoline storage tanks for an oil company major. The owner was no slouch. We had a class on waste disposal, we had all the equipment, respirators, airline masks, chem suits. The sludge was buried in the tank yard, in a fabric lined pit, with steel post markers at each end - all right in accordance with the law.
Fast forward 10+ years, mid '80s. I'm bored working for engineering outfits so I go back to work for the same petroleum piping contractor. And we get hired to go back in a clean up the leaded gas sludge pits. Laws have changed - the pits are now considered illegal dumping. New classes, called Hazmat classes now. New equipment, looks about the same, updated, and a few new pieces. We are digging up the pit, testing the dirt for tetraethyl lead, loading into over-pak drums and arranging for transportation to a waste disposal company.
It's a small town, everybody knows what is going on. We are at a Saturday night gathering (alcohol involved) and I gravitate to clump of young ladies.
One of them tears into me with, "How could you be so terrible and crap up the earth with this disgusting poisonous sludge?"
Good heavens lady. In the '70s we disposed of the sludge exactly in accordance with the law. The laws have changed and we are now hired to clean it up and dispose again in accordance with the current law. So tell me Snowflake, What would you suggest?:?
I didn't get lucky that night either.:weeping:
