(f) The Federal share payable on account of any repair or reconstruction provided for by funds made available under section 125 of this title shall not exceed 70 per centum of the cost thereof: Provided, That, in the case of any State containing nontaxable Indian lands, individual and tribal, and public domain lands (both reserved and unreserved) exclusive of national forests and national parks and monuments exceeding 5 per centum of the total area of all lands therein, the Federal share shall be increased by a percentage of the remaining cost equal to the percentage that the area of all such lands in such State, is of its total area: Provided further, That the Federal share payable on account of any repair or reconstruction of forest highways, forest development roads and trails, park roads and trails, parkways, public lands highways, public lands development roads and trails, and Indian reservation roads may amount to 100 per centum of the cost thereof, whether or not such highways, roads or trails are on any Federal-aid highway systems. The Secretary may increase the Federal share payable on account of any repair or reconstruction under this section up to 100 per centum of the replacement cost of a comparable facility if he determines it is in the public interest. As used in this section with respect to bridges and in section 144 of this title, "a comparable facility" shall mean a facility which meets the current geometric and construction standards required for the types and volume of traffic which such facility will carry over its design life. Any project agreement for which the final voucher has not been approved by the Secretary on or before the date of this Act may be modified to provide for the Federal share authorized herein.

(g) The Secretary is authorized to cooperate with the State highway departments and with the Department of the Interior in the construction of Federal-aid highways within Indian reservations and national parks and monuments under the jurisdiction of the Department of the Interior and to pay the amount assumed there for from the funds apportioned in accordance with section 104 of this title to the State wherein the reservations and national parks and monuments are located.

(h) At the request of any State, the Secretary may from time to time enter into agreements with such State to reimburse the State for the Federal share of the costs of preliminary and construction engineering at an agreed percentage of actual construction costs for each project, in lieu of the actual engineering costs for such project. The Secretary shall annually review each such agreement to insure that such percentage reasonably represents the engineering costs actually incurred by such State. (Pub.

(b) Sums authorized to be appropriated for forest development roads and trails shall be allocated by the Secretary of Agriculture according to the relative needs of the various national forests, taking into consideration the existing transportation facilities, value of timber or other resources served, relative fire danger, and comparative difficulties of road and trail construction.

(c) Sums authorized to be appropriated for public lands highways shall be allocated by the Secretary among those States having unappropriated or unreserved public lands, nontaxable Indian lands, or other Federal reservations, on the basis of need in such States, respectively, as determined by the Secretary upon application of the State highway departments of the respective States.

In the development of such comprehensive programs

due regard shall be given to the improvements which are necessary to conserve such waters for public water supplies, propagation of fish and aquatic life and wildlife, recreational purposes, and agricultural, industrial, and other legitimate use. For the purpose of this section, the Administrator is authorized to make joint investigations with any such agencies of the condition of any waters in any State or States, and of the discharges of any sewage, industrial wastes, or substance which may adversely affect such waters.

(2) The need for and the value of storage for this purpose shall be determined by these agencies, with the advice of the Administrator, and his views on these matters shall be set forth in any report or presentation to the Congress proposing authorization or construction of any reservoir including such storage.

(3) The value of such storage shall be taken into account in determining the economic value of the entire project of which it is a part, and costs shall be allocated to the purpose of water quality control in a manner which will insure that all project purposes share equitably in the benefits of multiple-purpose construction.

(4) Costs of water quality control features incorporated in any Federal reservoir or other impoundment under the provisions of this chapter shall be determined and the beneficiaries identified and if the benefits are widespread or national in scope, the costs of such features shall be nonreimbursable.

(c) Grants for administrative expenses of planning agencies; comprehensive pollution control and abatement plans for basins. (1) The Administrator shall, at the request of the Governor of a State, or a majority of the governors when more than one State is involved, make a grant to pay not to exceed 50 per centum of the administrative expenses of a planning agency for a period not to exceed 3 years, if such agency provides for adequate representation of appropriate State, interstate, local, or (when appropriate) international, interest in the basin or portion thereof involved and is capable of developing an effective, comprehensive water quality control and abatement plan for a basin.

(2) Each planning agency receiving a grant

under this subsection shall develop a comprehensive pollution control and abatement plan for the basin which

(A) is consistent with any applicable water quality standards established pursuant to current law within the basin;

(B) recommends such treatment works and sewer systems as will provide the most effective and economical means of collection, storage, treatment, and purification of wastes and recommends means to encourage both municipal and industrial use of such works and systems; and

(C) recommends maintenance and improvement of water quality standards within the basin or portion thereof and recommends methods of adequately financing those facilities as may be necessary to implement the plan.

(3) For the purposes of this subsection the term "basin" includes, but is not limited to, rivers and their tributaries, streams, coastal waters, sounds, estuaries, bays, lakes, and portions thereof, as well as the lands drained thereby.

waters of untreated or inadequately treated sewage or other wastes from sewers which carry storm water or both storm water and sewage or other wastes, or

(2) assisting in the development of any project which will demonstrate advanced waste treatment and water purification methods (including the temporary use of new or improved chemical additives which provide substantial immediate improvement to existing treatment processes) or new or improved methods of joint treatment systems for municipal and industrial wastes, and for the purpose of reports, plans, and specifications in connection therewith.
