Between 1 and 2 March 2022, the Department issued (6) Official Cautions to Load Ranger Pty Ltd (Load Ranger), Load & Go Pty Ltd (Load & Go), P.L. Tripodi Pty Limited (Tripodi), Attcall Civil Contractors Pty Ltd (Attcall), Hi-Quality Environmental Services Pty Ltd (Hi-Quality) and Rocktown Pty Ltd (Rocktown) for failure to adhere to restrictions on the use of a spoil haulage vehicle route (Route A), on the WestConnex M4-M5 Link Tunnel project (the project). The use of Route A by spoil haulage vehicles on the project is restricted to 7 am to 7 pm to minimise amenity impacts on surrounding residents. Spoil haulage vehicles operating on the project on behalf of Load Ranger, Load & Go, Tripodi, Attcall, Hi-Quality and Rocktown (separately) used Route A prior to 7 am on numerous occasions between June 2019 and May 2020. Since May 2020, additional management measures have been implemented on the project to better prevent and address any use of Route A outside the hours of 7 am to 7pm. The Department will continue to monitor compliance with conditions of approval.
