(i) Grazing privileges appurtenant to privately owned lands located within the park shall not be withdrawn until title to the lands to which such privileges are appurtenant shall have vested in the United States except for failure to comply with the regulations applicable thereto after reasonable notice of default.

(ii) Grazing privileges appurtenant to privately owned lands located outside the park shall not be withdrawn for a period of twenty-five years after September 14, 1950, and thereafter shall continue during the lifetime of the original permittee and his heirs if they were members of his immediate family as described herein, except for failure to comply with the regulations applicable thereto after reasonable notice of default.

(iii) Members of the immediate family are those persons who are related to and directly dependent upon a person or persons, living on or conducting grazing operations from lands, as of September 14, 1950, which the National Park Service recognized as base lands appurtenant to grazing privileges in the park. Such interpretation excludes mature children who, as of that date, were established in their own households and were not directly dependent upon the base lands and appurtenant grazing recognized by the National Park Service.

(iv) If title to base lands lying outside the park is conveyed, or such base lands are leased to someone other than a member of the immediate family of the permittee as of September 14, 1950, the grazing preference shall be recognized only for a period of twenty-five years from September 14, 1950.

(v) If title to a portion or part of the base land either outside or inside the park is conveyed or such base lands are leased, the new owner or lessee will take with the land so acquired or leased, such proportion of the entire grazing privileges as the grazing capacity in animal unit months of the tract conveyed or leased bears to the original area to which a grazing privilege was appurtenant and recognized. Conveyance or lease of all such base lands will automatically convey all grazing privileges appurtenant thereto.

(vi) Grazing privileges which are appurtenant to base lands located either inside or outside the park shall not be conveyed separately therefrom.

(i) A permittee whose grazing privilege is appurtenant to privately owned lands within the park will be granted total nonuse or reduced benefits for one or more years without nullifying his privilege in subsequent years.

(ii) A permittee whose privilege is appurtenant to base lands outside the park may be granted total nonuse on a year to year basis not to exceed three consecutive years. Total nonuse beyond this time may be granted if necessitated for reasons clearly outside the control of the permittee. Total unauthorized nonuse beyond three consecutive years will result in the termination and loss of all grazing privileges.

(iii) Whenever partial or total non-use is desired, an application must be made in writing to the Superintendent.

(i) The permittee and his employees shall use all possible care in preventing forest and range fires, and shall assist in the extinguishing of forest and range fires on, or within, the vicinity of the land described in the permit, as well as in the preservation of good order within the boundaries of the park.

(ii) The Superintendent may require the permittee before driving livestock to or from the grazing allotment to gather his livestock at a designated time and place for the purpose of counting the same.

(iii) Stock will be allowed to graze only on the allotment designated in the permit.

(iv) The permittee shall file with the Superintendent a copy of his stock brand or other mark.

(v) The permittee shall, upon notice from the Superintendent that the allotment designated in the permit is not ready to be grazed at the beginning of the designated grazing season, place no livestock on the allotment for such a period as may be determined by the Superintendent as necessary to avoid damage to the range. All, or a portion of the livestock shall be removed from the area before the expiration of the designated grazing season if the Superintendent determines further grazing would be detrimental to the range. The number of stock and the grazing period may be adjusted by the Superintendent at any time when such action is deemed necessary for the protection of the range.

(vi) No permit shall be issued or renewed until payment of all fees and other amounts due the National Park Service has been made. Fees for permits are due the National Park Service and must be paid at least 15 days in advance of the grazing period. No permit shall be effective to authorize grazing use thereunder until all fees and other amounts due the National Park Service have been paid. A pro rata adjustment of fees will be made in the event of reduction of grazing privileges granted in the permit, except that not more than 50 percent of the total annual grazing fee will be refunded in the event reduced grazing benefits are taken at the election of the permittee after his stock are on the range.

(vii) No building or other structure shall be erected nor shall physical improvements of any kind be established under the permit except upon plans and specifications approved by the National Park Service. Any such facilities, structures, or buildings may be removed or disposed of to a successor permittee within three months following the termination of the permit; otherwise they shall become the property of the United States without compensation therefor.

(viii) The permittee shall utilize the lands covered by the permit in a manner approved and directed by the Superintendent which will prevent soil erosion thereon and on lands adjoining same.

(ix) The right is reserved to adjust the fees specified in the permit at any time to conform with the fees approved for Teton National Forest, and the permittee shall be furnished a notice of any change of fees.
