The NWFSC provides scientific and technical support to NMFS for the management, conservation, and wise use of the Northwest region’s marine and anadromous resources.  At the Manchester Research Station this technical support includes the seawater rearing of Columbia River salmon stocks listed as threatened or endangered under the United States Endangered Species Act.  This is an action that aids in the recovery and rebuilding of these ESA listed stocks and is legally mandated mitigation for the operation of the Federal Columbia River Hydropower System as well as Biological Opinions for the Pacific Salmon Treaty.  Federal, state and tribal fish health agreements require that effluent water from tanks used for the rearing of fish sourced directly from the Columbia River and its tributaries be disinfected before it is discharged into Puget Sound.  This lowers the probability of Columbia River pathogens and parasites being transferred to fish naturally rearing in Puget Sound.  The Manchester Research Station complies with these interagency agreements by treating the effluent water from tanks containing wild-sourced Columbia River stocks with ozone.

In 2020 the facility is installing new ozone generators that require more oxygen than the existing, aged and now unreliable oxygen generator can supply.  This requires this older unit be replaced with new equipment that can meet or exceed existing supply needs.  With proper maintenance the equipment should be expected to have a 10 plus year operational life and should have an expected mean time between failures of 90,000 hours.  The new oxygen generator and accompanying compressor must meet or exceed all the oxygen supply specifications for the Station’s two new Ozone Water Systems OWS-600-GEN 2 ozone generators operating in parallel (both on at same time) and each at full capacity for 24 hours per day and 365 days per year.  The new oxygen generator and accompanying compressor must be a complete turnkey system that only requires hookup to power and existing oxygen supply lines to the ozone generators.
