Abagold WEC BAR - Anchor Environmental

ock to split apart. The cartridges do produce a high pressure over a short time frame and sowill produce noise.Blasting activities must be limited to one detonation series per day to avoid or reduce themortality of predators and seabirds attracted to fish kills from previous blasts.3. To mitigate the potential impacts to water quality the contractors must follow the followingconditions:Nonex must be used for all blasting.The casting of cement to create the base of the slot-slope wall must take place withinwatertight plastic canvas bags supported and shaped within metal frames with shutteringbeams.Adequate warning must be provided to neighbouring abalone farmers regarding the intendedtiming of any casting or blasting activities.A monthly schedule of planned activities is to be made available by Abagold and discussedwith all abalone farms.During periods when cement casting and/or blasting activities are planned, weekly activityschedules detailing the proposed dates for either activity must be provided to neighbouringabalone farms in advance. At least one days’ notice regarding changes to this schedule mustbe issued to all potentially affected farms.Construction activities (notably casting and blasting drilling operations) should be limited toweek days to ensure that there are personnel on site at the other abalone farms to respond toany incidents that may occur. Prior agreement should be sought from other abalone farms forcasting and blasting operations to be undertaken outside of these periods.4. To mitigate the potential impacts of litter on marine fauna the contractors must follow thefollowing conditions:All reasonable measures must be enforced to ensure there is no littering by constructionworkers.5. To mitigate the potential visual impacts of the proposed development the contractors andapplicants must follow the following conditions:The side walls of the buffer dams should be faced with rough stone, using the local sandstone,to blend with the surrounding rocky coastal landscape, similar to the rough stone facing on theexisting walls of the Abagold abalone farm.Ancillary structures, fencing, signage, and other vertical elements should be kept to anabsolute minimum to maintain the uncluttered, horizontal profile of the proposed buffer damwalls. Where signage is required, this should be fixed to walls instead of free-standing signs inorder to minimise visual clutter.No additional outdoor lighting should be introduced with the wave energy facility because ofthe visually exposed nature of the shorescape. Where external lighting is required for stepsetc. these should be low-level bulkhead type fittings with reflectors to prevent light spillage.All electrical and other cables should be located underground.Consideration should be given to creating an attractive graphic display of the wave energyfacility and an upgraded visitor centre for education purposes and to provide an attraction fortourists.17
