I refer to the Minister’s response to question on notice 1734, that 'DWER no longer intended to progress reclassification of part of Lot 9105 separately, and would instead address this matter in its report on the appeals'. The document Decision in Respect of Appeal Against Classification Contaminated Sites Committee (CSC 05/2018) Contaminated Sites Act 2003, Part 8, Division 2 for Maidment Parade and Hutt Drive, Dalyellup, otherwise known as the Greenpatch development (the site) does not document the intention of the Department of Water and Environmental Regulation (DWER) to reclassify a portion of the Greenpatch as ‘Remediated for Restricted Use’, and I ask: (a) did DWER address the matter of its intention to reclassify part of the area as ‘Remediated for Restricted Use’ during the appeal; (b) if yes to (a), why was the reclassification amended from ‘Remediated for Restricted Use’ to ‘Possibly Contaminated Investigation Required’ when it was confirmed by DWER the area contained treated solid residue, it was contaminated and needed restriction in use; and (c) if no to (a), why not?

(a)-(c) The Department of Water and Environmental Regulation briefly considered reclassifying a portion of the Greenpatch development as remediated for restricted use in September 2018, however, it was never given this classification under the Contaminated Sites Act 2003 (CS Act). By the time the Department prepared advice to the Contaminated Sites Committee on the appeal, it had further considered the available information on the contamination status of the relevant portion of Greenpatch. Taking into account the criteria in Schedule 1 to the CS Act and relevant guidelines, the Department formed the view that a classification of possibly contaminated – investigation required was more appropriate. Accordingly, the Department recommended a classification of possibly contaminated – investigation required for the portion of Greenpatch known as Area 8 and the Eastern Turning Circle to the Contaminated Site Committee.
