50 CFR 30.2: Disposition of surplus range animals.

Disposition shall be made only during regularly scheduled disposal program periods, except in the event of exigent circumstances affecting the animals, their range, or the recipient. The Refuge Manager is responsible for determining the existence of “exigent circumstances.” Surplus range animals may be disposed of, subject to State and Federal health laws and regulations, by donation for specific purposes to public agencies, public institutions, other governments or charitable institutions, or sold on the open market.
