(a) Yes. The Department of Environment Regulation (DER) has formally communicated with Gold Corporation, the owner of the site, on the requirement to investigate, monitor and assess the site in accordance with the
Contaminated Sites Act 2003
(CS Act). DER does not consult with the Contaminated Sites Committee on the requirement to investigate sites.
(b) The site, which consists of Lot 67 on Plan 215250, was classified as
possibly contaminated - investigation required
under section 13 of the CS Act on 7 February 2007. Further investigation is required to determine the nature and extent of any impact, followed by a risk assessment to determine whether the levels of substances present in soil, surface water or groundwater represent a risk of harm to human health, the environment or environmental values.
(c) Not applicable
(d) As the site has not yet been adequately investigated or assessed, it is not known if remediation will be required.
(e) DER has been advised that works (potentially including remediation), if required, are scheduled for March 2018.
