Tampa Bay Discharge Brought to an End

All discharges of untreated water to Port Manatee are currently ceased. As we deploy innovative technology on-site, the Florida Department of Environmental Protection’s (DEP) goal is to ensure that any future required discharges to the port are treated to reduce nutrients entering surrounding waterways and minimize possible ecological impacts such as algal blooms.

DEP continues to monitor and sample surrounding waterways following previous discharges from the NGS-South compartment to Port Manatee. Localized impacts to water quality were observed by DEP in the immediate zone of discharge at the port, which is to be expected at this time. By ceasing untreated discharge, ecological impacts to the area will be mitigated. Sampling efforts and monitoring are ongoing. There are no reported fish kills in the area.

Key status updates and response activities: 

  • At this time, discharges to Port Manatee have ceased.
  • Approximately 223 million gallons remain in the NGS-South compartment.
  • To date, approximately 215 million gallons have been discharged to the port.
  • DEP tasked two innovative technology companies to initiate nutrient reduction and removal treatments from water on-site prior to discharging to Port Manatee.
  • DEP deployed diving companies and submersible cameras and identified a seam separation on the east wall of the compartment. Field operations teams are working around the clock to implement necessary repairs to the liner to contain the flow. The flow of the seepage has reduced and remains contained onsite in the facility’s lined stormwater management system.
  • 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.
