Tribal enhancement and Federal research Net Pen general permit

Are the fish in these pens fed with feed containing PCBs and/ or other toxics? If so will these toxics enter state waters through excrement during containment or feed that is not consumed or through other related pathways. What steps will be taken i...↓f any to assure the lowest level of PCBs in feed are used? This concern has been identified for many years through fish hatchery permits and specific state purchasing requirements. Please refer to comments on those state and federal permits made over the last 10 years or so.These concerns should be addressed in Ecology's. 401 cert. Appropriate sampling and monitoring and control measures should be required to assess and prevent any increase in the levels of these toxics to state waters and sediments and eventual exposure to salmon, orcas and other species of concern. Lower level of toxics in feed can be found on the international feed market.Cost should not be an overriding consideration in this private enterprise.
