Geology and soil impacts during operation
The proposal would not increase the risk or likelihood for sediment-laden runoff or an
accidental spillage once operational. The operational management of these two
impacts forms an ongoing issue for Roads and Maritime outside of the context of this
proposal. Consequently, there would be no operational impacts.
6.8.4 Safeguards and management measures
Table 6-55 lists the geology and soils safeguards and management measures that
would be implemented to address the impacts identified above in section 6.8.3. The
management of accidental spills, management of sediment-laden runoff and control
of dust during construction are safeguarded under the proposed measures identified
in section 6.7.4 and section 6.12.4 respectively.
