Cooke Aquaculture permit modifications to raise steelhead
We determined the change of fish species from Atlantic salmon to steelhead is not likely to change the effect on water quality. So we modified the permits for the four facilities to allow Cooke Aquaculture to raise all-female, sterile steelhead (also known as rainbow trout). Because steelhead are native to Washington, they are not part of the 2018 law phasing out non-native species in marine fish farming by 2022. However, the modification does not extend the life of the permits, which expire in 2024. The current permits were originally issued to allow for two years of closure activities and monitoring after the facilities aquatic lands leases from the DNR expire in 2022. The location of the net pens are: one near Hope Island in Skagit Bay, and three in Rich Passage in Kitsap County (see maps below)
In the final modified permits, we included all water quality-related WDFW mitigations and took the opportunity to further strengthen the permit to protect water quality. Changes to the permits include:
- Clarifying that any fish reared in Cooke’s net pens are prohibited from release
- Adding requirements and details on how to notify state agencies of events that could potentially lead to fish escape
- Increasing monitoring and reporting of potential fish escape during stocking and harvesting
- Adding reporting for fish feed consumption
- Adding details on how nets must be maintained
- Adding a requirement to study new technologies and propose alternatives that reduce or prevent discharge of uneaten feed or metabolic waste
Comments on the permits
We held a comment period on draft modifications from Sept. 9 to Oct. 26, 2020, and a public workshop and hearing Oct. 14, 2020, to explain the proposed changes to the permits. There were a total of 147 comment submissions from individuals or organizations via eComments, email, mailed-in letters, and hearing testimony. We compiled all the comments submitted and reviewed each submission.
During this comment period, we received many comments that proposed additional changes to the permit and suggestions that were outside the scope of our permitting authority. Our Responsiveness Summary* contains a summary of comments we received and our responses.
*Note: Because the only difference between the four individual permits is the location (see permit links below), the permit information and responsiveness summary is the same for each facility. For ease of review, we have linked to the Clam Bay responsiveness summary (Appendix A) in the statement of Basis. However, you can find all of the documents for each location linked from the Facility Summary page below.
Why do net pen operations need a NPDES permit?
A NPDES permit is the tool that requires best management practices, monitoring, and reporting to ensure water quality standards are met. These facilities are operated to rear fish for harvest and market sale. Uneaten fish food and fish feces are the primary pollutants produced as a result of the operation of these facilities, as well as any accidental release of fish. The requirements in the permit allow us to enforce that facilities are meeting water quality standards.
