CONSTRAINT CLASSES 



CLASS DESCRIPTION 



1, Federal, state, or local regulations prohibit hydropower development. 



2. Potential Federal and state prohibitions (such as wilderness study 

 areas) . 



CRITERIA AND STANDARDS : 



Wild and Scenic Rivers - All such designated rivers will be class one but 

 considered along with other reaches for the other five resource areas. 



Wi lderness Areas and National Parks - All such designated rivers will be class 

 one and will not be considered along with other reaches in the other five 

 resource areas unless time permits. They can be excluded because it is presumed 

 that the land typed designation was not determined on the quality of the 

 streams. It is assumed that these streams represent a mix of value classes but 

 because of their inclusion in wilderness or National Parks designations will not 

 be developed for hydropower. 



Roadless Areas, National Natural Landmarks, Fish Hatcheries, Wildlife Refuges, 

 Biosphere Reserves - All such designated areas adjacent to rivers will be 

 classified a minimum of class two unless expert judgment warrants class one 

 designation. 



EVALUATION PROCESS 



Each constraint will be assigned to a senior resource expert for inclusion in 

 their categorization. River segments affected by Class I and TI constraints 

 will be m.apped at 1:100,000.
