 sludge deposits from the discharge of some 21 tons of 

 solids per day, and attendant water quality degradation 

 surrounding each mill source. Also the sludge deposit 

 formed by past Crown Zellerbach discharges continues to 

 seriously degrade water quality adjacent to that mill. 



Specifically, mill waste discharged into the harbor have 

 been shown to: ^ 



One, injure juvenile migrating salmon in 

 the harbor area . 



And secondly, form sludge deposits which 

 damage benthic organisms, produce harmful water quality 

 degradation, and result in general aesthetically unattrac- 

 tive conditions. 



Of greater importance to marine life in the 

 study area, however, is the presence of dilute sulfite 

 waste liquor in waters throughout the Port Angeles study 

 area from Fibreborad and from Rayonier. Such wastes, even 

 at the low concentrations, 10 parts per million, have been 

 found harmful to immature forms of fish and shellfish. 

 Bioassay studies in the Port Angeles area show that 

 extensive damages occur to oyster larva at waste levels 

 found in surface waters of the harbor and eastward along- 

 shore to Dungeness Spit. On the basis of other bioassay 

 studies reported for Bellingham and Everett it may also be
