The Water Corporation is looking to complete initial exploratory work to assess the best location for a proposed desalination plant for a future Perth water supply option. Industry feedback sought by 18 May 2018.
This involves assessing the immediate sub-sea terrain and includes low-level “seismic” work and core sample drilling, inshore off the coast north of Perth at Alkimos.
This is not the in-depth oil and gas level seismic, rather geophysical level work ie significantly lower pulse / sound waves and to a depth level of 25 metres (versus hundred metres / 1,000 metres plus for oil and gas exploration seismic at a significantly higher acoustic level).
Key points of particular relevance to rock lobster fishers are:
- Subject to approvals, they plan to commence this work in June
- The geophysical work, depending on the weather, will take approximately three weeks to complete
- During this time there will be a temporary exclusion zone (see yellow shading on the map)
- The exclusion zone is only during geophysical work
- The Water Corporation has requested that fishing equipment is removed from the exclusion zone during this period.
- The geotechnical work (core sample drilling) will start straight after the geophysical work has been completed
- The drill sites are indicated on the attached map, final sites will be determined by the geophysical work
- The overall exclusion zone will be removed, there will be a 25 metre radius exclusion zone only around the drilling rig
- The drilling rig will be delineated by four lit yellow buoys (one on each corner), approximately one metre in height plus it will also have flashing lights.
If you have any comments or concerns relating to your fishing operations please provide comment to Clare@westernrocklobster.org by COB Friday 18 May 2018 for inclusion in a WRL submission.
