Storm Bay

​​​​​​​​​​​​​​​​​​​​​​​​​The EPA regulates finfish farming at marine farming leases MF281 Yellow Bluff (western Storm Bay) and MF279 West of Wedge Island (eastern Storm Bay).

The location of the above finfish farms and associated environmental licences can be accessed via the EPA Regulated Premises layer on LISTmap. See our Site Information​ page for details.​

The Marine Farming Development Plans for the region are available on the Department of Natural Resources and Environment Tasmania website.

Environmental Licence Renewals​​​

On 15 January 2024, the EPA ​​decided to renew for a 5-year period the environmental licences in the Storm Bay Regional Area due to expire on 30 November 2023.

Environmental licences and conditions can be accessed via the EPA Regulated Premises layer on LISTmap. ​

Management Determinations and​ Directions

The EPA issues Environmental Licences and makes determinations under the Environmental Standards for Tasmanian Marine Finfish Farming 2023​. This includes determinations of Regional Areas and the setting of Total Permissible Dissolved Nitrogen Output (TPDNO). TPDNO determinations also provide a share (apportionment) of the total TPDNO to each company that has active Environmental Licences for marine finfish farming in the Regional Area.​​​

Determination of Storm Bay Regional ​​​​Area

Marine finfish farming in areas within Storm Bay has previously been assessed and monitored under different programs. Ongoing research has made it apparent that a monitoring strategy that is integrated across all habitats in the Storm Bay region is required to adequately detect any potential effects of marine finfish farming and to implement improved management.

In order to ensure all significant benthic and pelagic habitats in all relevant parts of the Storm Bay Region are monitored the EPA has determined the Storm Bay Regional Area. This will enable improvements to the Broadscale Environmental Monitoring Program (BEMP) and the determination of Total Permissible Dissolved Nitrogen Outputs (TPDNO).

On 14 November 2023, the EPA Director, pursuant to Section 2(1) of the Environmental Standards, has determined that the Storm Bay Regional Area includes:

All areas south of the entrance to the River Derwent, south of the entrance to Frederick Henry Bay and north of a line drawn across the southward extent of Storm Bay.​

Biogeochemical modelling of salm​​on farming scenarios for Storm Bay Regional Area

In 2020, the CSIRO commenced a four-year research project to develop a biogeochemical model for Storm Bay and to run modelling scenarios investigating potential environmental effects from expansion of salmon farming in Storm Bay and Nubeena. The EPA has reviewed CSIRO’s final project report released in March 2023 (Storm Bay Biogeochemical Modelling Final Report March 2023) and has prepared the following report in its consideration of setting a sustainable level of salmon farming within the Storm Bay Regional Area.

CSIRO's modelling project looked at three different levels of salmon farming expansion within Storm Bay and provided information on the range of potential environmental impacts that may be caused by the three levels of expansion. The EPA has reviewed the project information and is satisfied that the first level of farming expansion investigated in the project will not cause significant environmental impacts within Storm Bay and is the most appropriate starting point for a limit on salmon farming within Storm Bay.

The main form of pollution that comes from salmon farming is from the dissolved nitrogen contained within the fish wastes. Salmon feed contains high levels of nitrogen to help the fish grow, and this nitrogen can cause environmental impacts once the feed has been eaten and some of the nitrogen is released from the salmon as waste products. Because dissolved nitrogen waste is the main pollutant from salmon farming, the EPA manages salmon farming environmental impacts by limiting the amount of dissolved nitrogen waste that can be released from salmon grown within a defined area or region in Tasmania. Based on the outputs of the modelling, the EPA intends to cap the level of farming within Storm Bay at 1,590 tonnes of dissolved nitrogen output per year (referred to as Total Permissible Dissolved Nitrogen Output (TPDNO)) for all salmon farms within Storm Bay. This was the first level of Storm Bay development investigated by CSIRO in their research project, which also investigated dissolved nitrogen outputs of 2,295 tonnes per year and 3,180 tonnes per year.

The EPA requires all salmon farming companies to undertake a comprehensive environmental monitoring program within Storm Bay, Nubeena, Frederick Henry Bay and Norfolk Bay and the results of this monitoring will allow the EPA to track environmental performance to ensure that salmon farming does not cause significant impacts on the environment. Further expansion of salmon production within Storm Bay will be achieved through a staged approach managed by the EPA and salmon farming companies will only be allowed to increase the amount of salmon that they can farm once they have shown that the current level of farming is not having a significant impact on the environment and that all environmental licence requirements are satisfied.

Medicated feed containing antibiotics (active ingredient: Trimethoprim) was applied at 12 pen bays over a 10-day period in January 2022 at the Yellow Bluff finfish farm in the Storm Bay. This measure became necessary due to an infection with Vibrio anguillarum. These events were supported by relevant Veterinary Authorisations (VAs) and were subject to comprehensive monitoring requirements stipulated by the EPA. Sampling of wild fish and sediment occurred on three occasions between 31 January and 9 May 2022.​
