(i) As established for use in the East Zone, the Wyoming Coordinate System shall be named, and in any land description in which it is used it shall be designated, the "Wyoming Coordinate System NAD 1983, East Zone." The following counties will use Wyoming Coordinate System NAD 1983, East Zone: Laramie, Albany, Platte, Niobrara, Converse, Weston, Crook, Campbell, and Goshen;

(ii) As established for use in the East Central Zone, the Wyoming Coordinate System shall be named, and in any land description in which it is used it shall be designated, the "Wyoming Coordinate System NAD 1983, East Central Zone." The following counties will use Wyoming Coordinate System NAD 1983, East Central Zone: Carbon, Natrona, Johnson, Sheridan, Washakie, and Big Horn;

(iii) As established for use in the West Central Zone, the Wyoming Coordinate System shall be named, and in any land description in which it is used it shall be designated, the "Wyoming Coordinate System NAD 1983, West Central Zone." The following counties will use Wyoming Coordinate System NAD 1983, West Central Zone: Sweetwater, Fremont, Hot Springs, and Park;

(iv) As established for use in the West Zone, the Wyoming Coordinate System shall be named, and in any land description in which it is used it shall be designated, the "Wyoming Coordinate System NAD 1983, West Zone."
