 investigations of conditions in Port Angeles Harbor and are 

 submitting herewith a summary of those observations. 



During December I96I 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. Per- 

 sonnel 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.

 The deposition area attributable to waste- 

 water discharge from the Fibreboard mill covers an area 

 of about 115 acres and, in general, was found to occupy 

 a segment of a circle with a radius of about 2500 feet 

 lying northerly and easterly of the mill. This area amounts 

 to about 3-'^ percent of the area of the bottom of the Port 

 Angeles Harbor as a whole. 



Bottom deposits in general did not exceed 

 24 inches in depth. At the outer edges, the deposition
