Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 2647
Title: Pollution Reduction Program 7 - Wyong South and Charmhaven Effluent Ponds Transfer Pump Upgrades
Start date: 30 Jul 2021
 
Licence Condition
Background The licensee notified the EPA of overtopping events at the Wyong South STP Wet Weather Storage Pond in 2020 and in 2021 due to rainfall events. The licensee notified the EPA of an uncontrolled discharge from the Charmhaven Wet Weather Storage Pond in 2021 due to a rainfall event. The licensee has advised the EPA of difficulties in drawing down both ponds prior to and following rainfall events due to the current capacity of effluent transfer pumps at both Wyong South and Charmhaven STPs. The current pump capacities at both plants compromises the licensee's ability to efficiently draw down pond volumes in a timely manner prior to and following rainfall events. The licensee provided a report to the EPA detailing the proposed effluent pump capacity upgrades for both the Wyong South Wet Weather Storage Pond and the Charmhaven Balance Pond to the Toukley STP prior to discharge to the Norah Head Ocean Outfall.
