The Secretary of the Interior shall approve only such comprehensive plans or projects as may be substantial in character and design and the expenditure of funds hereby authorized shall be applied only to such approved comprehensive fishery plan or projects and if otherwise applied they shall be replaced by the State before it may participate in any further apportionment under this chapter. No payment of any money apportioned under this chapter shall be made on any comprehensive fishery plan or project until an agreement to participate therein shall have been submitted to and approved by the Secretary of the Interior.
If the State elects to avail itself of the benefits of this chapter by preparing a comprehensive fish and wildlife plan under option (1) of subsection (a) of this section, then the term “project” may be defined for the purpose of this chapter as a fishery program, all other definitions notwithstanding.
Administrative costs in the form of overhead or indirect costs for services provided by State central service activities outside of the State fish and game department charged against programs or projects supported by funds made available under this chapter shall not exceed in any one fiscal year 3 per centum of the annual apportionment to the State.
The Secretary of the Interior may enter into agreements to finance up to 75 per centum of the initial costs of the acquisition of lands or interests therein and the construction of structures or facilities from appropriations currently available for the purposes of this chapter; and to agree to finance up to 75 per centum of the remaining costs over such a period of time as the Secretary may consider necessary. The liability of the United States in any such agreement is contingent upon the continued availability of funds for the purposes of this chapter.
