 In addition, in-plant improvements 

 initiated have resulted in substantial reduction of the 

 fiber load discharged to the receiving waters. In 1964 

 an additional step was taken by the closing of our sul- 

 fite pulp mill, which eliminated the discharge of a major 

 portion of the mill's BOD load. Now no chemical pulp is 

 manufactured at our Port Angeles division. The elimina- 

 tion of the spent sulfite liquor resulted in an over-all 

 mill BOD reduction of 70 percent. 



It is a well known fact that water move- 

 ment in the Strait of Juan de Fuca is swift and mixing 

 and dilution of effluents discharged at our Port Angeles 

 mill are rapid. No evidence of sludge deposits had been 

 noted in the vicinity of our outfalls and no sugnificant 

 depression of the dissolved oxygen concentration 

 attributable to these discharges has been noted. In fact, 

 no significant change of water quality has been detected 

 which would preclude the use of these waters for other 

 purposes . 



Our observations are confirmed by the follow- 

 ing statement taken from Page 461 of the Federal Water 

 Pollution Control Administration report entitled 

 "Pollutional Effects of Pulp and Paper Mill Wastes in 

 Puget Sound" issued in March 1967:
