Back in the 80s there was a pier off City Island, Bronx, NY that had a manhole near the end. Unmarked tanker trucks carrying whatever waste would park next to it and drop a hose through the manhole to off load into Long Island Sound. Worked great until one driver didn’t replace the cover and the SHTF. Far as I know, no one was ever arrested or charged.
Around the same time I would drive the LIE near the Fair Grounds around 3AM. I would often see a dripping, gunk covered tanker truck highballing from the Island toward the city. One look and you just knew it was bad news.
In 1980, I lived on City Island, on a 115 ft.Yacht named the “Global Star”, at the City Island Marina. That was the best job I’ve ever had. We delivered it from Grosse Pointe
Yacht Club to West Palm Beach, Fl. in two Months.
