EIA Review Approach
BKS has reviewed and analysed the available specialist and supporting reports that were performed as part of the Environmental Scoping Report (ESR) (up to January 2004), as well as the bridging reports undertaken (between January 2004 and October 2006). The purpose of this review was to identify possible constraints and impacts that could have been overlooked, classify the subsequent steps to be followed in assembling the required information for the EIA process and identify potential changes to the identified mitigation measures.
The following reports have been reviewed and analysed:
|
 |
Council for Geoscience: Geological Survey (CGS): Feasibility level investigation for the proposed Spring Grove Dam (Report No 1999-0051); |
