 viater conditions at our Port Angeles plant, we find no 

 justification to the requirements for removal of sludge 

 bed and the installation of discharge line 50 feet below 

 the surface of the water. 



To substantiate the above statement, we 

 would like to read a copy of Brown and Caldwell's letter 

 of September 1 dealing with the subject. 



"Waste disposal, Port Angeles mill. 



"As you requested, we have reviewed reports 

 and other data collected in the course of our oceanographic 

 investigations of conditions in Port Angeles Harbor and 

 are submitting herewith a summary of those observations. 



"During December 1961 our firm conducted 

 an underwater investigation in the harbor offshore from 

 the Port Angeles mill to determine the extent of deposition 

 and the apparent effects on marine life in the vicinity. 

 Personnel involved in the work were sanitary engineers, 

 one of whom was a scuba diver, a biological oceanographer , 

 and professional scuba divers. The underwater work was 

 carried out for a total of seven days and also included 

 inspection of areas in both Port Angeles Harbor and at 

 Neah Bay, 75 miles westward, where conditions were unaffected 

 by pulp mill discharges. Underwater photographs were taken 

 and detailed field notes were kept.
