Keep America's Refuges Operational Act This bill amends the Fish and Wildlife Act of 1956 to reauthorize through FY2022: (1) the volunteer services, community partnerships, and national wildlife refuge education programs of the National Wildlife Refuge System; and (2) provisions authorizing the Department of the Interior to accept and use gifts, devises, or bequests of real and personal property for the benefit of the U.S. Fish and Wildlife Service in the performance of its activities and services. The bill eliminates the prohibition on the use for the operation or administration of any nonfederal entity of any federal funds that are used for a project or program for a national wildlife refuge or a complex of geographically related refuges under a cooperative agreement between Interior and a partner organization, academic institution, state or local government agency, or other person under the community partnerships program.
