Dismiss EPA quashes all West Gate Tunnel landfill approvals Normal text size Advertisement Victoria's environmental watchdog has overturned all of the approvals it has given to landfills set to accept the West Gate Tunnel's contaminated soil, in what has been described as a "monumental stuff up" that has shattered the public's faith in the regulator. The Environment Protection Authority confirmed on Thursday that it had revoked environmental approvals it gave to a further two landfills, Hi-Quality in Bulla and Cleanaway Ravenhall, which were set to accept up to 3 million tonnes of soil contaminated with chemicals known as PFAS.
