Inherent in the duty imposed on any agency by NEPA
to promote environmental quality is the obligation to weigh the possible environmental effects
of a proposal against the effects on other public
- Values theagency is mandated to consider. -_If the |
emvironmental effects are adverse,
the agency must
consider whether they outweigh the benefits of the
proposal in deciding whether to go ahead.

implicit requirement is confirmed by the directive
of Section 102(2)(B) that agencies develop methods
for giving "presently unquantified environmental
amenities and values ... appropriate consideration
in decisionmaking along with economic and technical
considerations."
