What is the “non-impairment standard” used in managing WSAs?
The IMP describes the FLPMA-mandated non-impairment standard, which directs the BLM to manage and protect wilderness characteristics of WSAs until the Congress acts. Section 603(c) of the FLPMA states that “. . . until Congress has determined otherwise, the Secretary shall continue to manage such lands according to his authority under the Act and other applicable law in a manner so as not to impair the suitability of such areas for preservation as wilderness . . ..” The general standard for management of WSAs is to not allow actions or impacts that will preclude Congress’s prerogatives in either designating the areas as wilderness or releasing them for other non-wilderness uses.
