(a) Cooperative agreements for all projects which involve financial contributions from cooperators shall be negotiated, approved, and executed in accordance with procedures prescribed by the Chief.

(b) Cooperative funds contributed in advance shall be deposited in the United States Treasury to the credit of the Forest Service Cooperative Fund authorized by the Act of June 30, 1914 (38 Stat. 430), as amended; 16 U.S.C. 498, or the Act of March 3, 1925 (43 Stat. 1132), as amended; 16 U.S.C. 572, which deposits will be made available for expenditure from the appropriation “Cooperative Work, Forest Service.” If a State, county or other governmental agency is unable to contribute funds under the Act of March 3, 1925, as amended, in advance but is able to pay its share subsequent to performance of the work, the subsequent payment of such funds will be deposited to the credit of the Forest Service appropriation from which the expenditures were made or to appropriations for similar purposes currently available at the time of deposit.
