QuestionView source ↗

I refer to the unlined Dalyellup Waste Residue Disposal Facility (DWRDF) with millions of tonnes of treated solid residue (TSR) from the production of titanium dioxide pigment, buried in a modified swale between the vegetated linear primary dunes and the parabolic secondary dunes, covering an area of around 91,000m2 with a depth around seven metres Australian height datum (AHD) and an approximate maximum elevation of 24 metres AHD which will be exposed to rising sea levels and coastal processes, and I ask : (a) what is the Government doing to make sure the DWRDF will be adequately contained; and (b) what is the Government doing to make sure the DWRDF will not pose a health risk for the community?

(a) – (b) The Dalyellup Waste Residue Disposal Facility (DWRDF) is regulated under Ministerial Statements 213 and 332 as well as a Closure Notice served under the Environmental Protection Act 1986 , and is also classified as remediated for restricted use under the Contaminated Sites Act 2003 . These regulatory instruments ensure that public health, the environment and environmental values are protected. Requirements and action that need to be taken under these regulatory instruments are set out in a Site Management Plan for the DWRDF. I tabled the latest version of the Site Management Plan on 12 November 2020 (tabled paper 4615).
