(2) Any Power Repayment Study (PRS) submitted for this purpose must be developed using currently approved rates for estimating future revenues. If the filed rates differ from the current rates, the Administrator must provide a PRS which uses the level of revenues produced by the proposed rates. Unless otherwise required by statute, a PRS must contain only those investments in plant which will be in commercial operation during the proposed rate approval period, except replacements.

If rates and charges have not been formulated on a cost related basis, the basis for each rate or charge should be explained.

The Administrator must request waiver of any requirement of this subpart if an application that does not fully comply with that requirement is not to be considered deficient. The request must state the Administrator's reasons for such noncompliance and show good cause for any waiver.

Any application for Commission review and approval of a rate or rate schedules established by the Administrator of the Bonneville Power Administration pursuant to section 7(k) of the Pacific Northwest Electric Power Planning and Conservation Act must be filed in compliance with the provisions of § 35.13(a)(2) of part 35 of this chapter and with the provisions of this part, and must include the classifications, practices, rules and regulations affecting the rate and charges and all contracts which in any manner affect or relate to such rate, charges, classifications, services, rules, regulations, or practices. However, such classifications, practices, rules, regulations or contracts which may affect or relate to rates will not be subject to Commission approval unless they are determined to be rates or rate schedules.
