On 1 March 2022, the Department issued a $15,000 Penalty Notice to ResourceCo Material Solutions Pty Ltd (ResourceCo) 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 ResourceCo used Route A prior to 7 am on numerous occasions between November 2019 and April 2020. ResourceCo was advised in November 2019 that its vehicles were using Route A contrary to the restrictions on its use, however its vehicles continued using Route A outside of the approved hours until April 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.
