Page 96, 2.2.4. Municipal - Industrial 



This section discusses point source pollution discharges by municipal and industrial 

 entities, but presents tabular information that is very misleading. A table listing the 

 number of stream miles "adversely affected" by such parameters as low dissolved 

 oxygen, bacteria, turbidity, elevated stream temperatures, etc. is presented in a manner 

 that implies that municipal and industrial sources are the cause of this pollution. 

 However, the data in this table actually reflects an assessment of statewide nonpoint 

 pollution problems from a multitude of land use activities. The report cited for this 

 information (ODEQ 1990) indicates that municipal and industrial sources are a minor 

 component of the pollution problems, and that the majority of stream miles affected are 

 attributed to forestry and agricultural practices: a figure in the ODEQ report identifies 

 the relative sources of pollution as forestry (17.4%), agriculture (17.4%), municipal 

 (2.4%), industrial (0.8%), mining (5.2%), etc. 



"...some 1,062 miles of river reaches that do not support beneficial uses 

 by point source municipal pollution. " 



". ..some 386 miles of river reaches are listed as impaired by point 

 source industrial pollution. . . " 



In the second statement, the actual number of miles affected by point source municipal 

 pollution is reported as 368 miles by ODEQ (1990). 



If the analysis is restricted to basins containing anadromous salmonids (the focus of the 

 OFIC report), the correct estimates of stream reaches impacted by point source 

 pollution would be 1 ,036 miles for municipal pollution, and 342 miles for industrial 

 pollution. 



Additionally, for comparative purposes it should be noted that the estimated river 

 reaches impacted by nonpoint sources of pollution are 6,380 miles for forestry 

 activities, and 5,915 miles for agriculture activities (excluding basins without 

 anadromous salmonids). 



Page 98, 2.2.5. Mining 



This discussion of historical mining in Oregon provides very little information 

 concerning the effects of mining activities on salmonid habitat or salmonid 

 productivity. Additional literature review should be completed to assess the potential 

 effects of these activities on salmonids. 



The authors cite ODEQ (1990) in stating that: 



". . .some 2,280 miles of streams potentially adversely affected by non- 

 point (sic) source mining problems. " 



The estimate of miles affected is correct if all basins in Oregon are considered. 

 However, if the analysis is restricted to basins with anadromous salmonids the actual 

 estimate of stream reaches affected by mining is 1,840 miles.
