The manager of a Bed-Stuy company that polishes metal surgical equipment, meat hooks, and aircraft components has pled guilty to rigging a secret, underground pipeline from his facility in central Brooklyn all the way to Newtown Creek, in order to illegally dump industrial waste into an adjacent sewer system.

Granted, this is just the latest in a long string of chemical abuses wrought on the creek/Superfund site that separates Greenpoint from Long Island City, dubbed by one affectionate expert the "poison cauldron."

58-year-old Manuel Acosta of Kew Gardens is the current manager of Control Electropolishing Corp., which, according to its website, has been polishing metal parts in New York since the late 1950s.

According to official court documents, Acosta and his employees sent unprocessed sludge to the creek on a regular basis between November 2013 and the following January. The waste was heavy with chromium, copper, lead and nickel. Even though Acosta's waste went through the Newtown Creek Water Pollution Control Plant before entering the creek itself, the plant doesn't have the capacity to process these pollutants.

The Department of Environmental Protection inspected Control Electropolishing on multiple occasions during the dumping period, but Acosta managed to keep his illegal pipeline a secret by plugging it up on inspection days.

Yesterday Acosta pled guilty to "discharging into the waters of the state," in violation of the Environmental Conservation law. His company pled guilty to endangering public health and disposing hazardous waste without authorization.

As part of the plea agreement, Acosta and the company will pay a fine of $110,000 to New York State's Department of Environmental Conservation and the Brooklyn DA's office. A sentencing date has been set for December 16th.

"This case should make clear that we take environmental crimes in Brooklyn seriously and will vigorously prosecute any company that dumps environmental toxins into our waterways," Brooklyn DA Ken Thompson said yesterday.
