Phase one of Lake Munmorah remediation begins

The NSW Environment Protection Authority (EPA) has approved a Voluntary Management Proposal (VMP) for the former Lake Munmorah Power Station site on the Central Coast, kicking off the first phase of a complex remediation process.  

Part of the site was declared significantly contaminated in April last year due to PFAS and petroleum hydrocarbon pollution, stemming from the historical operation of the coal-fired power station and past use of fire-fighting foams containing PFAS at the site. 

NSW EPA Executive Director of Operations, Jason Gordon said the recently approved Voluntary Management Proposal (VMP) is a critical first step in ensuring the former coal-fired power station site is remediated effectively.

“This is a complicated remediation project, and we must allow enough time to get it right,” Mr Gordon said.  

“Under the VMP, the site’s current owner will work with environmental consultants to gather detailed information about the contaminants, including how they move through soil and water. 

“Taking the time to thoroughly assess the onsite contamination will ensure the remediation approach selected is suitable and fit-for-purpose to achieve the best long-term outcomes for the community and surrounding environment. 

“We know the community is invested in the clean-up of this site and we’re working closely with the owner to ensure they proactively engage them about the process, as per the requirements of the VMP.” 

Following completion of the first Voluntary Management Proposal, site owner Generator Property Management Pty Ltd (GPM) will submit a second VMP (Phase 2) outlining the implementation of the remediation approach.

The EPA is overseeing the remediation process as part of the site’s regulation under the Contaminated Land Management Act 1997 (CLM Act).  

Parts of the site impacted by the contamination have been fenced off for several years and are not considered to pose a risk to the surrounding community. Testing has also confirmed that seafood in the Tuggerah Lakes System – connected to Lake Munmorah – remains safe to eat as part of a balanced diet.
