    Mayfield

     

    HCCDC has led complex remediation works at the former BHP site in Mayfield since 2006.

    The site is owned by Property NSW and by contract, HCCDC manages $110 million program of works that includes:

    • an underground ‘barrier wall’ to reduce groundwater flow to the Hunter River
    • low permeability capping, reducing infiltration of rainwater
    • new major stormwater drains
    • demolition and land forming
    • a new freight rail line
    • major civil works.

    The completion of works will be a major achievement for the local community and a significant milestone in its history and will enable productive reuse and redevelopment of the site. 

    Kooragang Island

     

    The Kooragang Island Waste Emplacement Facility (KIWEF) site was originally operated by BHP as a waste landfill facility to receive waste from the former Newcastle Steelworks. 

    HCCDC was tasked by the NSW Government to complete the closure of the former landfill site in accordance with the requirements of the NSW Environment Protection Authority.

    The closure works are proposed to be undertaken in an area containing State and Federally listed threatened species including the Green and Golden Bell Frog (Litoria aurea), several migratory bird species and the nearby internationally listed Hunter Estuary Wetlands Ramsar site. 

    HCCDC has already coordinated the closure of 30 hectares of the KIWEF site on behalf of Government and has advanced plans to complete the remaining 32 hectares of the former landfill site. 

    All closure works have been designed to be sympathetic to other approved projects nearby and provide movement corridors that connect the Green and Golden Bell Frog habitats across Kooragang Island. 

    The KIWEF site is included within the Port of Newcastle long term lease area and, once closure works are completed, will come under the care and control of the Port of Newcastle.

    Site history

     

    The BHP Steelworks at Mayfield was established in 1915 and was vital to the regional and national economies until it closed in 1999. Memorials to all those who worked at the Steelworks remain on the Mayfield site.

    The first, called Muster Point, is a large steel art installation paying tribute to the steel working skills on the BHP workers.

    Another memorial installation was unveiled at the centenary of the plant’s official opening on June 2, 1915, paying tribute to those who lost their lives at the steelworks. The sculpture is a moving ‘’mourning circle’’ produced by Branxton artist and blacksmith Will Maguire.

    NSW Premier's Award

    In October 2016, HDC received a NSW Premier’s award in the environmental category for its work to date on the remediation of the site. The works are expected to come to a close soon, which will mark one of the biggest and most important remediation projects in Newcastle’s history.
