For the purpose of these regulations, reserve areas also include lands in Hawaii, the Commonwealth of Puerto Rico, Guam, and the Virgin Islands, which were initially administered by the United States through Act of Congress, Executive Order, Public Land Order or Proclamation of the President and administered, either solely or primarily, by the Secretary through the Service.
(c) The term county means any county, parish, organized or unorganized borough, township or municipality, or other unit of local government that is the primary collector for general purpose real property taxes where fee areas and/or reserve areas are located. For the purpose of sharing revenues, the Commonwealth of Puerto Rico, Guam, and the Virgin Islands shall each be treated as a county.
(d) The term fund means the revenues received by the Service from (1) the sale or disposition of animals, salmonoid carcasses and eggs, products of the soil (including, but not limited to, timber, hay, and grass), minerals, shells, sand, and gravel; (2) leases for public accommodations or facilities incidental to, but not in conflict with, the basic purpose of such areas; and (3) other privileges, including industrial leases at Crab Orchard National Wildlife Refuge, Illinois, as authorized by Section 8 of Pub. L. 95-616, approved October 27, 1978. The Service may pay from such fund any necessary expenses incurred in connection with the revenue producing and revenue sharing activity. The fund shall also include any appropriations authorized by the Act to make up any difference between the total amount of receipts after payments of expenses and the total amount of payments due the counties.
