GPM works with all levels of Government and relevant authorities to ensure that all work carried out site meets all essential safety and health standards.
GPM’s work at the former Munmorah Power Station saw more than 97% of all material recycled.
GPM is now concentrating on addressing remediation issues at the former power station in Munmorah, in line with Environmental Protection Authority (EPA) guidelines.
At Lidsdale, GPM’s key focus will be planning for and then undertaking the safe closure of the Kerosene Vale Ash Repository and the Sawyers Swamp Creek Ash Dam and then appropriately remediating the balance of the site for permanent closure.
