1996—Puspan. L. 104–127 substituted “the protection, management, and improvement of the National Forest System” for “the protection and improvement of the national forests”, inserted “management,” after “protection,” in two places, and inserted at end “Payment for work undertaken pursuant to this section may be made from any appropriation of the Forest Service that is available for similar work if a written agreement so provides and reimbursement will be provided by a cooperator in the same fiscal year as the expenditure by the Forest Service. A reimbursement received from a cooperator that covers the proportionate share of the cooperator of the cost of the work shall be deposited to the credit of the appropriation of the Forest Service from which the payment was initially made or, if the appropriation is no longer available, to the credit of an appropriation of the Forest Service that is available for similar work. The Secretary of Agriculture shall establish written rules that establish criteria to be used to determine whether the acceptance of contributions of money under this section would adversely affect the ability of an officer or employee of the Department of Agriculture to carry out a duty or program of the officer or employee in a fair and objective manner or would compromise, or appear to compromise, the integrity of the program, officer, or employee. The Secretary of Agriculture shall establish written rules that protect the interests of the Forest Service in cooperative work agreements.”

1928—Act May 29, 1928, struck out provision which required that annual reports be made to Congress of moneys received as contributions for cooperative work.
