The Secretary of Agriculture shall develop utilization standards, methods of measurement, and harvesting practices for the removal of trees, portions of trees, or forest products to provide for the optimum practical use of the wood material. Such standards, methods, and practices shall reflect consideration of opportunities to promote more effective wood utilization, regional conditions, and species characteristics and shall be compatible with multiple use resource management objectives in the affected area. To accomplish the purpose of this subsection in situations involving salvage of insect-infested, dead, damaged, or down timber, and to remove associated trees for stand improvement, the Secretary is authorized to require the purchasers of such timber to make monetary deposits, as a part of the payment for the timber, to be deposited in a designated fund from which sums are to be used, to cover the cost to the United States for design, engineering, and supervision of the construction of needed roads and the cost for Forest Service sale preparation and supervision of the harvesting of such timber. Deposits of money pursuant to this subsection are to be available until expended to cover the cost to the United States of accomplishing the purposes for which deposited: Provided, That such deposits shall not be considered as moneys received from the national forests within the meaning of sections
500 and
501 of this title: And provided further, That sums found to be in excess of the cost of accomplishing the purposes for which deposited on any national forest shall be transferred to miscellaneous receipts in the Treasury of the United States.
