the engineering feasibility of the proposed construction;

the estimated cost of the proposed construction;

the part of the estimated cost which can properly be allocated to irrigation and probably be repaid by the water users;

the part of the estimated cost which can properly be allocated to power and probably be returned to the United States in net power revenues;

the part of the estimated cost which can properly be allocated to municipal water supply or other miscellaneous purposes and probably be returned to the United States.

The Secretary is authorized to enter into contracts to furnish water for municipal water supply or miscellaneous purposes: Provided, That any such contract either (A) shall require repayment to the United States, over a period of not to exceed forty years from the year in which water is first delivered for the use of the contracting party, with interest not exceeding the rate of 3½ per centum per annum if the Secretary determines an interest charge to be proper, of an appropriate share as determined by the Secretary of that part of the construction costs allocated by him to municipal water supply or other miscellaneous purposes; or (B) shall be for such periods, not to exceed forty years, and at such rates as in the Secretary’s judgment will produce revenues at least sufficient to cover an appropriate share of the annual operation and maintenance cost and an appropriate share of such fixed charges as the Secretary deems proper, and shall require the payment of said rates each year in advance of delivery of water for said year. Any sale of electric power or lease of power privileges, made by the Secretary in connection with the operation of any project or division of a project, shall be for such periods, not to exceed forty years, and at such rates as in his judgment will produce power revenues at least sufficient to cover an appropriate share of the annual operation and maintenance cost, interest on an appropriate share of the construction investment at not less than 3 per centum per annum, and such other fixed charges as the Secretary deems proper: Provided further, That in said sales or leases preference shall be given to municipalities and other public corporations or agencies; and also to cooperatives and other nonprofit organizations financed in whole or in part by loans made pursuant to the Rural Electrification Act of 1936 [7 U.S.C. 901 et seq.]. Nothing in this subsection shall be applicable to provisions in existing contracts, made pursuant to law, for the use of power and miscellaneous revenues of a project for the benefit of users of water from such project. The provisions of this subsection respecting the sales of electric power and leases of power privileges shall be an authorization in addition to and alternative to any authority in existing laws related to particular projects and reserve to the Secretary the exclusive authority to develop small conduit hydropower using Bureau of Reclamation facilities and pumped storage hydropower exclusively using Bureau of Reclamation reservoirs. No contract relating to municipal water supply or miscellaneous purposes or to electric power or power privileges shall be made unless, in the judgment of the Secretary, it will not impair the efficiency of the project for irrigation purposes.

The Bureau of Reclamation shall apply its categorical exclusion process under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.) to small conduit hydropower development under this subsection, excluding siting of associated transmission facilities on Federal lands.

The Power Resources Office of the Bureau of Reclamation shall be the lead office of small conduit hydropower policy and procedure-setting activities conducted under this subsection.

Nothing in this subsection shall obligate the Western Area Power Administration, the Bonneville Power Administration, or the Southwestern Power Administration to purchase or market any of the power produced by the facilities covered under this subsection and none of the costs associated with production or delivery of such power shall be assigned to project purposes for inclusion in project rates.

Nothing in this subsection shall alter or impede the delivery and management of water by Bureau of Reclamation facilities, as water used for conduit hydropower generation shall be deemed incidental to use of water for the original project purposes. Lease of power privilege shall be made only when, in the judgment of the Secretary, the exercise of the lease will not be incompatible with the purposes of the project or division involved, nor shall it create any unmitigated financial or physical impacts to the project or division involved. The Secretary shall notify and consult with the irrigation district or water users association operating the transferred conduit before offering the lease of power privilege and shall prescribe terms and conditions that will adequately protect the planning, design, construction, operation, maintenance, and other interests of the United States and the project or division involved.

Nothing in this subsection shall alter or affect any existing agreements for the development of conduit hydropower projects or disposition of revenues.

Nothing in this subsection shall alter or affect any existing preliminary permit, license, or exemption issued by the Federal Energy Regulatory Commission under Part I of the Federal Power Act (16 U.S.C. 792 et seq.) or any project for which an application was filed with the Federal Energy Regulatory Commission before August 9, 2013, and is still pending.

That the Secretary may fix a development period for each irrigation block, if any, of not to exceed ten years from and including the first calendar year in which water is delivered for the lands in said block; and that during the development period water shall be delivered to the lands in the irrigation block involved at a charge per annum per acre-foot, or other charge, to be fixed by the Secretary each year and to be paid in advance of delivery of water: Provided, That where the lands included in an irrigation block are for the most part lands owned by the United States, the Secretary, prior to execution of a repayment contract, may fix a development period, but in such case execution of such a contract shall be a condition precedent to delivery of water after the close of the development period: Provided further, That when the Secretary, by contract or by notice given thereunder, shall have fixed a development period of less than ten years, and at any time thereafter but before commencement of the repayment period conditions arise which in the judgment of the Secretary would have justified the fixing of a longer period, he may amend such contract or notice to extend such development period to a date not to exceed ten years from its commencement, and in a case where no development period was provided, he may amend such contract within the same limits: Provided further, That when the Secretary shall have deferred the payment of all or any part of any installments of construction charges under any repayment contract pursuant to the authority of the Act of September 21, 1959 (73 Stat. 584), he may, at any time prior to the due date prescribed for the first installment not reduced by such deferment, and by agreement with the contracting organization, terminate the supplemental contract by which such deferment was effected, credit the construction payments made, and exercise the authority granted in this section. After the close of the development period, any such charges collected and which the Secretary determines to be in excess of the cost of the operation and maintenance during the development period shall be credited to the construction cost of the project in the manner determined by the Secretary.

That the part of the construction costs allocated by the Secretary to irrigation shall be included in a general repayment obligation of the organization; and that the organization may vary its distribution of construction charges in a manner that takes into account the productivity of the various classes of lands and the benefits accruing to the lands by reason of the construction: Provided, That no distribution of construction charges over the lands included in the organization shall in any manner be deemed to relieve the organization or any party or any land therein of the organization’s general obligation to the United States.

That the general repayment obligation of the organization shall be spread in annual installments, of the number and amounts fixed by the Secretary, over a period of not more than 40 years, exclusive of any development period fixed under paragraph (1) of this subsection, for any project contract unit or, if the project contract unit be divided into two or more irrigation blocks, for any such block, or as near to said period of not more than forty years as is consistent with the adoption and operation of a variable payment formula which, being based on full repayment within such period under average conditions, permits variance in the required annual payments in the light of economic factors pertinent to the ability of the organization to pay.

That the first annual installment for any project contract unit, or for any irrigation block, as the case may be, shall accrue, on the date fixed by the Secretary, in the year after the last year of the development period or, if there be not development period, in the calendar year after the Secretary announces that the construction contemplated in the repayment contract is substantially completed or is advanced to a point where delivery of water can be made to substantially all of the lands in said unit or block to be irrigated; and if there be no development period fixed, that prior to and including the year in which the Secretary makes said announcement water shall be delivered only on the toll charge basis hereinbefore provided for development periods.

publish notice of the proposed contract or amendment in newspapers of general circulation in the affected area and shall make reasonable efforts to otherwise notify interested parties which may be affected by such contract or amendment, together with information indicating to whom comments or inquiries concerning the proposed actions can be addressed; and

provide an opportunity for submission of written data, views and arguments, and shall consider all substantive comments so received.
