(a) Road improvement. Use of a road for commercial hauling, except occasional or minor amounts, will be conditioned upon improvement or supplemental construction of the road to safety and economically serve the contemplated use, unless the Chief determines that the safety and economy of the established and foreseeable use by the United States, its users and cooperators will not be impaired by the use for which application is being made. With the consent of the Chief the applicant may deposit funds in the estimated amount required for the improvements or supplemental construction in lieu of performance. Such funds will be used by the Forest Service to do the planned work. The cost of the improvements or supplemental construction will be taken into account in determining any otherwise required contribution to cover the proportionate share of the cost of road acquisition, construction, reconstruction or improvement attributable to the use.

(b) Corresponding benefits. Corresponding benefits which may be accepted by the Chief for sharing road use will be those which bear a reasonable relation to the management of lands administered by the Forest Service. They may be in the form of:

(c) Cost determinations for roads cooperatively constructed under agreements. When roads are constructed under cooperative agreements to meet mutual needs of the United States and others for access, determinations of the shares of costs to be borne by the United States and the cooperating parties will include consideration of:

(d) Cost recovery by the United States from others. When roads are used under permit for commercial hauling instead of under cooperative agreement, any cost to be recovered by the United States will be calculated in proportion to the planned use of the road. The road cost used in such calculation will be the amount or estimated amount expended in the acquisition, construction, reconstruction, and improvement of that capacity of the road required to serve the use needs of all parties that are or reasonably can be expected to use the road. The road costs shall not exceed the replacement value of the road. Such road share-cost payments will be through deposits in advance of use unless the user provides a payment bond satisfactory to the Chief guaranteeing that payments will be made promptly upon billing by the Forest Service.

(e) Cost sharing with a cooperator. The costs to achieve the agreed upon road or road system may be met by:

(f) Road maintenance and resurfacing. Cooperators will share the road maintenance and resurfacing costs under suitable agreements to perform, arrange for performance by others, or by making deposits with the Forest Service which will be used to pay the cost of work necessary to keep such roads in satisfactory condition commensurate with use requirements of each cooperator. No cooperator shall be required to perform or bear such costs other than those occasioned by its individual use. Other users will bear costs in accordance with § 212.5(d).

(g) Interests to be acquired by the United States in roads or easements therefor. Where the United States is to bear or share the cost of constructing or improving, or acquiring a road system, a road, or a segment thereof, or acquires an easement therefor, the interest acquired will:
