Onslow Marine Support Base Stage 2 Capital Dredging

Closed 24 Aug 2017

Opened 17 Aug 2017

Overview

Onslow Marine Support Base Pty Ltd is proposing to modify and extend the Beadon Creek harbour approach channel, turning basin and berth pocket as part of Stage 2 of the Onslow Marine Support Base (OMSB) proposal.

The proposed capital dredging will enable offshore supply vessels to access the newly constructed OMSB land-backed wharf facility (Stage 1) within the Beadon Creek Maritime Facility.

930,000 cubic metres of dredge material will be disposed of onshore to a 44 hectare Dredge material Management Area (DMMA) adjacent to the Onslow airport. The material is proposed for future reuse to develop and extend the Light Industrial Area in Onslow. Dredge spoil return water will be released to the intertidal flats between the DMMA and the western tributary of Beadon Creek.

Why We Are Consulting

At this initial stage of the EIA process, comment is simply sought on whether or not the EPA should assess a proposal and, if so, what level of assessment is considered appropriate.

What Happens Next

Following the seven day public comment period and consideration of any comments received, the EPA will decide whether or not this proposal requires environmental impact assessment and, if so, what level of assessment will be applied.

The EPA's decisions on level of assessment are released each Monday on the EPA's website.
