CATEGORY DESCRIPTION ; 



Institutional constraints are comprised of laws or 

 policies with direct implications for hydropower 

 development imposed and/or administered by agencies of 

 government at the Federal, state or local level, or by 

 the Tribes. Institutional constraints may prohibit, 

 significantly limit, or otherwise impose conditions on 

 hydropower development. For purposes of this survey 

 only the potential prohibitions are included. Other 

 constraints would be addressed in an actual siting 

 study. 



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 ; 



W ild and Sc e nic Rivers - All such designated rivers 

 were Class I but considered along with other reaches 

 for the other five resource areas. 



Wilder ness-Ar_eas_and_Nat_ional_Paxiis ~ All such 

 designated rivers were Class I and will not be con- 

 sidered 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 Hatch- 

 eries, Wildlife Refuges, Biosphere Reserves - All such 

 designated areas adjacent to rivers were classified a 

 minimum of class two unless expert judgment warrants 

 class one designation. 



EVALUATION PROCESS 



Each constraint was assigned to a senior resource 

 expert for inclusion in their categorization. River 

 segments affected by Class I and II constraints were 

 mapped at 1:100,000.
