Piney Point breach: How did we get here? Piney Point history timeline By Sierra McLean | April 6, 2021 at 10:50 PM EDT - Updated April 6 at 10:52 PM MANATEE COUNTY, Fla. (WWSB) - ABC7 has been following the situation at Piney Point closely for over a week now. We have to ask: How did we get here? Well, the plant at Piney Point opened in 1966 as a subsidiary of the Borden Company. By 1970, fish kills at Bishop Harbor were being blamed on operations at the plant. Through the 1980s and 1990s, new owners Royster Phosphates and the Mulberry Corporation went belly up. And by 2004, the Environmental Protection Commission had taken over the property, then returned it over to the State Department of Environmental Protection to run.
