An assessment will be conducted at the Empire Bay Marina to examine the site's contamination levels and help inform future actions.
Parliamentary Secretary for the Central Coast Adam Crouch said a detailed assessment has been commissioned by the Department of Planning, Industry and Environment – Crown Lands.
"The NSW Government was forced to revoke the Empire Bay Marina licence in September 2020 due to ongoing safety and environmental concerns, and a failure by the licence holder to rectify issues despite repeated requests," Mr Crouch said.
"Crown Lands is issuing a factsheet to keep local residents informed every step of the way on what has occurred to date, and what is planned for the future."
Minister for Water Property and Housing Melinda Pavey said the detailed assessment would determine the type, extent and level of contamination on the site and advise on requirements for site remediation.
"This contamination assessment, together with building assessments, will help inform next steps," Mrs Pavey said.
"The Marina structures and building are in poor condition and unsafe and have been fenced off to the public. Residents are advised not to enter the site."
Crown Lands has instructed boat owners to remove their vessels from the marina prior to the contamination assessment getting underway.
"Central Coast Ferries has committed to moving their vessel to an alternative mooring location. There will be no disruption to the regular ferry service," Mrs Pavey said.
"If boat owners fail to vacate the marina the Department will be required to take compliance action which would involve fines of up to $1,100 for individuals and $2,200 for corporations and the impounding of vessels."
Crown Lands will maintain responsibility for the control and management of the marina site until a decision is made about its future.
