43 U.S. Code § 2405 - Feasibility studies
Not later than 18 months after December 22, 2006, the Secretary shall promulgate criteria (including the feasibility factors listed under subsection (c)) under which the feasibility studies shall be assessed for completeness and appropriateness.
The Secretary shall include in the criteria promulgated under paragraph (1) methods to scale the level of effort needed to complete the feasibility assessment relative to the total size and cost of the proposed rural water supply project and reduce total costs to non-Federal entities.
Except as otherwise provided in this subsection, the Federal share of the cost of a feasibility study carried out under this section shall not exceed 50 percent of the study costs.
The non-Federal share under paragraph (1) may be in the form of any in-kind services that the Secretary determines would contribute substantially toward the conduct and completion of the study.
The Secretary may increase the Federal share of the costs of a feasibility study if the Secretary determines, based on a demonstration of financial hardship, that the non-Federal participant is unable to contribute at least 50 percent of the costs of the study.
In addition to the non-Federal project entity, the Secretary shall consult and cooperate with appropriate Federal, State, tribal, regional, and local authorities during the conduct of each feasibility assessment and development of the feasibility report conducted under this subchapter.
 So in original. No par. (2) has been enacted.
