subject to conditions including completion of the environmental audit into the suitability of the site from a contamination perspective for the proposed and permitted uses.
Environment—former petrol station sites
(Question No 283)
Mrs Jones asked the Minister for the Environment and Sustainable Development, upon notice, on 13 May 2014:
(1) Which vacant petrol station sites have “complex remediation issues”, as you stated on 15 May 2013.
(2) What are the complex remediation issues.
(3) What action has been taken to ensure that the remediation process will be completed as quickly as possible.
(4) When will the remediation process be complete on each site.
Mr Corbell: The answer to the member’s question is as follows:
(1) Which vacant petrol station sites have “complex remediation issues”, as you stated on 15 May 2013.
The following vacant petrol station sites have complex remediation issues:
Blocks 16 & 17 Section 29 Braddon – Former Ampol Service Station
Blocks 1 & 2 Section 25 Griffith – Former Mobil Service Station
Block 10 Section 12 Higgins – Former Shell Service Station
Block 3 Section 41 Lyneham – Former Caltex Service Station
Block 13 Section 28 Narrabundah – Former Ampol Service Station
Block 1 Section 17 Watson – Former Mobile Service Station
Block 1405 Tuggeranong – Former Caltex Service Station
(2) What are the complex remediation issues.
As outlined in my statement of 15 May 2013, the remediation of some service stations can be very complex and potentially time consuming if, for example, contamination of groundwater has occurred and/or the location is geologically complex.
Groundwater impacts have been identified at each of the sites mentioned earlier.
Remediation at these sites is complex due the complex nature of the geology in the ACT. Groundwater in the ACT is typically stored in fracture rock aquifers. The groundwater in these aquifers is stored in the fissures, fractures and cavities within the bedrock. Access to the groundwater is greatly dependent on the size and nature of the fractures and their interconnections.
