Abagold WEC BAR - Anchor Environmental

some of the impacts were anticipated and much consideration was givento reducing or eliminating these impacts through the use of innovativeconstruction methods. These methods are described in detail above forAlternatives 1 and 2 and will be applied for Alternative 3. The impacts towater quality resulting from the construction and operation ofAlternative 3 are, like Alternatives 1 and 2 expected to be of lowsignificance prior to mitigation. However the positioning of the southernside wall of the WEC dam for Alternative 3 is directly in front of theAquafarm intake sump. This will impact the intake of water by Aquafarmsignificantly as the channel will be cut off by the wall.StatusExtentDurationIntensityProbability ofoccurrenceCumulative impactprior to mitigationSignificance prior tomitigationDegree to which impactcan be mitigatedProposed mitigationNegativeLocalLong termHighDefiniteHighHIGHLowAdditional management measures were requested by the neighbouringabalone farmers to reduce the potenmtial impacts of alterations towater quality.
