J. 0. JULSON 3^7 



My name is J. 0. Julson, Director, Air 

 Water Resources for Weyerhaeuser Company. 



Weyerhaeuser Company operates three saw- 

 mills, a kraft pulp mill, and a sulfite pulp mill in and 

 adjacent to the City of Everett, Washington. 



Process effluents from the sawmills essen- 

 tially are clarified waters from hydraulic barking. These 

 clarified waters discharge into the Snohomish River with 

 very little loading. Sanitary wastes from these mills 

 are presently being treated in septic tanks, but these 

 wastes will soon be pumped into the City of Everett's 

 sanitary sewage system for treatment. 



The kraft pulp mill discharges through 

 two effluent streams; one which carries a small amount 

 of fibre empties into the Snohomish River. The main 

 effluent from this mill receives primary settlement treat- 

 ment in lagoons, which discharge only on outgoing tides. 



A significant reduction in the discharge 

 of soluble solids has resulted from close monitoring 

 practices and from a strong program of process water re- 

 use. A further reduction in settleable solids discharge 

 is expected when revisions to the lagoons are completed 

 in 1968. 



The sulfite mill discharges its main load 

 through the deep water diffuser line used jointly by Scott and
