STATEMENT OF HERMAN AMBERG 

 MANAGER OF MANUFACTURING SERVICES 

 CROWN ZELLERBACH CORPORATION 



DR. AMBERG: Mr. Chairman, Conferees. 



My name is Herman Amberg. I am Manager 

 of Manufacturing Services for Crown Zellerbach Corpora- 

 tion. I live in Camas, Washington, where I am assigned 

 to the company's Central Research Division. 



I am here today to describe the water 

 quality control program which has been under way for 

 several years at our Port Angeles Division. 



Our industrial involvement in Port Angeles 

 is a 500-ton-per-day newsprint and printing paper mill 

 with three paper machines. The mill's daily production 

 of 400 tons of groundwood is made in part by conventional 

 stone grinders and in part by disc refiners. 



The company several years ago recognized 

 the potential problems which could develop through con- 

 tinuous discharge of pulp and paper machine effluents 

 into the inner Port Angeles Harbor. An extensive in- 

 plant control program was started several years ago which 

 involved rerouting of the plant sewers. This program is 

 completed and now all process effluents have been removed 

 from the inner harbor and are presently discharged into 

 the Strait of Juan de Fuca.
