    Mayfield

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

    The site is owned by NSW Government Properties and by contract, HDC 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

    Remediation of 60 hectares of land on the former BHP waste facility at Kooragang Island is being undertaken by HDC. BHP used this landfill site during its Newcastle Steelworks operations and HDC is working to bring the site up to the environmental standard set by the NSW Environment Protection Authority.

    This project protects the port environment and will enable future employment-generation uses on the site. HDC has already coordinated remediation works on 33 hectares of the site and has advanced plans for remediation of the remaining 27 hectares, which is suited to a range of activities in both medium and large scale industrial development.

    The land is part of the Port of Newcastle lease and when the remediation work is complete, the land management will revert to the Port.

    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 a close soon, which will mark one of the biggest and most important remediation projects in Newcastle’s history.
