(a) The Department of Environment and Conservation (DEC) is not aware of any "conditional environmental approval", however the proposed site of the Carnarvon Police and Justice Complex at 135 Robinson Street, Morgantown was classified
remediated for restricted use
under the
Contaminated Sites Act 2003
on 3 September 2010.
(b)-(c) No air quality monitoring devices are required at the site. Twice yearly groundwater quality monitoring, for a period of two years from September 2010, is required. No devices other than groundwater monitoring wells are required for this purpose.
(d) The former site occupier has accepted responsibility for monitoring groundwater at the site for a two-year period. Based on recent monitoring data provided to DEC, the limited remaining hydrocarbon impacts to groundwater are continuing to decline or naturally attenuate. Provided this trend continues, further groundwater monitoring will not be required.
