United States who is charged with responsibility for establishing such 
fees has advised the Governor of the affected State, or an agency of 
the State designated by the Governor for this purpose, of his intention 
so to do, and said officer shall, before finally establishing such fees, 
give consideration to any recommendation that the Governor or his 
designee may make with respect thereto within said sixty days and

requirements during the ensuing fiscal year for appropriations from 
the fund. In the absence of a provision to the contrary in the Act 
making an appropriation from the fund, (i) the appropriation therein 
made shall be available in the ratio of 60 per centum for State pur-
poses and 40 per centum for Federal purposes, but (ii) the President 
may, during the first five years in which appropriations are made from 
the fund, vary said percentages by not more than 15 points either way 
to meet, as nearly as may be, the current relative needs of the States 
and the Federal Government. 
(b) ADVANCE APPROPRIATIONS; REPAYMENT.—Beginning with the 
third full fiscal year in which the fund is in operation, and for a total 
of eight years, advance appropriations are hereby authorized to be 
made to the fund from any moneys in the Treasury not otherwise

for each fiscal year. Such advance appropriations shall be available 
for Federal and State purposes in the same manner and proportions as 
other moneys appropriated from the fund. Such advance appropria-
tions shall be repaid without interest, beginning at the end of the next 
fiscal year after the first ten full fiscal years in which the fund has 
been in operation, by transferring, annually until fully repaid, to the 
general fund of the Treasury 50 per centum of the revenues received 
by the land and water conservation fund each year under section 2 of 
this Act prior to July 1, 1989, and 100 per centum of any revenues 
thereafter received by the fund. Revenues received from the sources 
specified in section 2 of this Act after July 1, 1989, or after payment 
has been completed as provided by this subsection, whichever occurs 
later, shall be credited to miscellaneous receipts of the Treasury. The 
moneys in the fund that are not required for repayment purposes may 
continue to be appropriated and allocated in accordance with the proce-
dures prescribed by this Act. 
FINANCIAL ASSISTANCE TO STATES 
SEC. 5. GENERAL AUTHORITY; PURPOSES.—(a) The Secretary of the 
Interior (hereinafter referred to as the "Secretary") is authorized to 
provide financial assistance to the States from moneys available for 
State purposes. Payments may be made to the States by the Secretary 
as hereafter provided, subject to such terms and conditions as he con-
siders appropriate and in the public interest to carry out the purposes 
of this Act, for outdoor recreation: (1) planning, (2) acquisition of 
land, waters, or interests in land or waters, or (3) development. 
(b) APPORTIONMENT AMONG STATES; NOTIFICATION.—Sums appro-
priated and available for State purposes for each fiscal year shall be 
apportioned among the several States by the Secretary, whose deter-
mination shall be final, in accordance with the following formula: 
(1) two-fifths shall be apportioned equally among the several 
States; and 
(2) three-fifths shall be apportioned on the basis of need to 
individual States by the Secretary in such amounts as in his judg-
ment will best accomplish the purposes of this Act. 
The deter-
mination of need shall include amon^ other things a consideration 
of the proportion which the population of each State bears to the 
total population of the United States and of the use of outdoor 
recreation resources of individual States by persons from outside 
78 STAT. ] 
PUBLIC LAW 88-578-SEPT. 3, 1%4 
901 
the State as well as a consideration of the Federal resources and 
programs in the particular States. 
The total allocation to an individual State under paragraphs (1) 
and (2) of this subsection shall not exceed 7 per centum of the total 
amount allocated to the several States in any one year. 
The Secretary shall notify each State of its apportionments; and 
the amounts thereof shall be available thereafter for payment to such 
State for planning, acquisition, or development projects as hereafter 
prescribed. Any amount of any apportionment that has not been paid 
or obligated by the Secretary during the fiscal year in which such 
notification is given and for two fiscal years thereafter shall be reap-
portioned by the Secretary in accordance with paragraph (2) of this 
subsection. 
The District of Columbia, Puerto Rico, the Virgin Islands, Guam, 
and American Samoa shall be treated as States for the purposes of this 
title, except for the purpose of paragraph (1) of this subsection. Their 
population also shall be included as a part of the total population in 
computing the apportionment under paragraph (2) of this subsection. 
(c) MATCHING REQUIREMENTS.—Payments to any State shall cover 
not more than 50 per centum of the cost of planning, acquisition, or 
development projects that are undertaken by the State. The remain-
ing share of the cost shall be borne by the State in a manner and with 
such funds or services as shall be satisfactory to the Secretary. No 
payment may be made to any State for or on account of any cost or 
obligation incurred or any service rendered prior to the date of 
approval of this Act. 
(d) COMPREHENSIVE STATE PLAN REQUIRED; PLANNING PROJECTS.— 
A comprehensive statewide outdoor recreation plan shall be required 
prior to the consideration by the Secretary of financial assistance for 
acquisition or development projects. The plan shall be adequate if, 
in the judgment of the Secretary, it encompasses and will promote the 
purposes of this Act. The plan shall contain— 
(1) the name of the State agency that will have authority to 
represent and act for the State in dealing with the Secretary for 
purposes of this Act; 
(2) an evaluation of the demand for and supply of outdoor 
recreation resources and facilities in the State; 
(3) a program for the implementation of the plan; and 
(4) other necessary information, as may be determined by the 
Secretary. 
The plan shall take into account relevant Federal resources and pro-
grams and shall be correlated so far as practicable with other State, 
regional, and local plans. Where there exists or is in preparation for 
any particular State a comprehensive plan financed in part with funds 
supplied by the Housing and Home Finance Agency, any statewide 
outdoor recreation plan prepared for purposes of this Act shall be 
based upon the same population, growth, and other pertinent factors 
as are used in formulating the Housing and Home Finance Agency 
financed plans. 
The Secretary may provide financial assistance to any State for 
projects for the preparation of a comprehensive statewide outdoor 
recreation plan when such plan is not otherwise available or for the 
maintenance of such plan.

projects or combinations thereof if they are in accordance with the 
btate comprehensive plan:

land, waters, or interests in land or waters (other than land, 
waters, or interests in land or waters acquired from the United 
States for less than fair market value), but not including inci-
dental costs relating to acquisition. 
(2) DEVELOPMENT.—For 
development, 
including but not 
limited to site planning and the development of Federal lands 
under lease to States for terms of twenty-five years or more. 
(f) REQUIREMENTS FOR PROJECT APPROVAL; CONDITION.—Payments 
may be made to States by the Secretary only for those planning, 
acquisition, or development projects that are approved by him. No 
payment may be made by the Secretary for or on account of any 
project with respect to which financial assistance has been given or 
promised under any other Federal program or activity, and no finan-
cial assistance may be given under any other Federal program or 
activity for or on account of any project with respect to which such 
assistance has been given or promised under this Act. The Secretary 
may make payments from time to time in keeping with the rate of 
progress toward the satisfactory completion of individual projects: 
Provided^ That the approval of all projects and all payments, or any 
commitments relating thereto, shall be withheld until the Secretary 
receives appropriate written assurance from the State that the State 
has the ability and intention to finance its share of the cost of the 
particular project, and to operate and maintain by acceptable stand-
ards, at State expense, the particular properties or facilities acquired 
or developed for public outdoor recreation use. 
Payments for all projects shall be made by the Secretary to the 
Governor of the State or to a State official or agency designated by the 
Governor or by State law having authority and responsibility to 
accept and to administer funds paid hereunder for approved projects. 
If consistent with an approved project, funds may be transferred by 
the State to a political suodivision or other appropriate public agency. 
No property acquired or developed with assistance under this sec-
tion shall, without the approval of the Secretary, be converted to other 
than public outdoor recreation uses. The Secretary shall approve such 
conversion only if he finds it to be in accord with the then existing 
comprehensive statewide outdoor recreation plan and only upon such 
conditions as he deems necessary to assure the substitution of other 
recreation properties of at least equal fair market value and of reason-
ably equivalent usefulness and location. 
No payment shall be made to any State until the State has agreed 
to (1) provide such reports to the Secretary, in such form and con-
taining such information, as may be reasonably necessary to enable 
the Secretary to perform his duties under this Act, and (2) provide 
such fiscal control and fund accounting procedures as may be necessary 
to assure proper disbursement and accounting for Federal funds paid 
to the State under this Act. 
Each recipient of assistance under this Act shall keep such records 
as the Secretary of the Interior shall prescribe, including records 
which fully disclose the amount and the disposition by such recipient 
of the proceeds of such assistance, the total cost of the project or 
undertaking in connection with which such assistance is given or used, 
and the amount and nature of that portion of the cost of the project or 
undertaking supplied by other sources, and such other records as 
will facilitate an effective audit.
