Baseline Monitoring Survey

A comprehensive baseline survey was conducted in June 2017 in accordance with the Director’s requirements. This included video surveys, benthic infauna sampling, threatened species survey, sediment chemistry and physical characteristics as well as mapping of reef and seagrass communities in the vicinity. The Baseli​​ne Environmental Assessment Final Report July 2017 was endorsed by the Director EPA prior to finfish farming commencing on the Okehampton Bay lease. ​

Marine Farming Licence

The marine farming aspects of the lease are regulated under Marine Farming Licence 236. Enquiries about marine farming licences should be directed to the Marine Farming Branch of ​​​DPIPWE. 

Environmental Licence

While environmental conditions were originally incorporated into the Marine Farming Licence, a separate Envir​onmental Licence​ has subsequently been issued to regulate the environmental aspects of finfish farming at Okehampton Bay. The Environ​​mental Licence has been issued to Tassal, the actual operator of the finfish farming activity. Tassal conduct salmon farming on a portion of the lease under a sublease agreement with Spring Bay Seafoods. 

  Environmental Licence 10172/2   (14Mb)

Key requirements of the Environmental Licence are comprehensive monitoring, preparation of publicly available Annual Environmental Reports and modelling of water dispersion and sediment distribution. ​

Monit​oring Requirements

The scope of the extensive monitoring program introduced through the Environmental Licence includes water quality, benthic infauna and sediment monitoring as well as surveys of seagrass beds and reefs. Water quality monitoring is required at far-​​field (BEMP) sites as well as close to the lease boundary. The monitoring regime also includes biannual video surveys under pen bays and along the lease boundary, which is more frequent than for other marine farms.

The program is designed to generate reliable information to allow the analysis of impacts associated with the operation of the lease and attempts to be consistent with previous scientific studies undertaken in the area. Data collected through the​​ program will provide early detection of potentially harmful effects and thereby provide opportunities for adaptive management practices.

Independent monitori​n​g undertaken by the EPA

In addition to operational monitoring to be undertaken by Tassal, EPA has been conducting independent monitoring​​ of water quality around the Okehampton Bay since August 2017. The program scope is outlined in the document EPA Monitoring Program for O​kehampt​on Bay Marine Farm. Further information is available on the Monitoring Program page.

Annual Environmental Report (AER)​

Tassal are required submit an Annual Environmental Report (AER) as a condition of their Environmental Licence.

Hydrodynamic Modelling Report

Hydrodynamic dispersion modelling in relation to Okehampton Bay marine farming activities is required under the conditions of the Environmental Licence. Modelling was conducted by CSIRO on behalf of Tassal, with high frequency input data collected by several sensors. A report has been prepared to illustrate the main hydrodynamic dispersal patterns for far-field and near-field situations for a passive tracer.​
