Piney Point Update - April 10, 2021 


This week, DEP deployed diving companies and submersible cameras that identified a seam separation on the east wall of the NGS-South. Dive operations have strategically placed a steel plate on the seam separation to temporarily repair this identified source of concentrated seepage. At this time, the plate has been installed and we will continue to monitor the success of this repair. We continue to work to identify whether there are any additional separations of the liner.

In anticipation of weekend weather forecasts, DEP has made preparations for managing increased stormwater on-site due to anticipated heavy rain and wind. DEP is coordinating with state meteorologists and response teams will remain on-site throughout the foreseen weather event.

Key status updates and response activities:  

  • At this time, discharges to Port Manatee are still ceased.
  • Approximately 217 million gallons remain in the NGS-South compartment. To date215 million gallons were discharged to the port.
  • Sampling efforts and monitoring are ongoing. DEP’s interactive water quality dashboard details sampling locations and corresponding results to evaluate any environmental impacts to Tampa Bay from the Piney Point discharges. Results will continue to be posted as soon as they are available. 
  • DEP tasked two innovative technology companies to initiate nutrient reduction and removal treatments from water on-site prior to discharging to Port Manatee. These technologies are on-site preparing for operation.
