80.13—Substantiality in character and design.
         All projects proposed for funding under the Acts must be substantial in character and design. A substantial project (for fish and wildlife purposes) is one which:
    
    
    
    
        
        (c) 
         Utilizes accepted fish and wildlife conservation and management principles, sound design, and appropriate procedures; and
    
    
        
        (d) 
         Will yield benefits which are pertinent to the identified need at a level commensurate with project costs.
