Text: 26 Consistent with FERC's prior announcements that any change in the Quality Bank methodology would be prospective, the settlement agreement contained no provision for refunds to shippers who had paid more into the Quality Bank under the gravity methodology than they would be assessed under the assay methodology, even though the former had been found to be no longer just and reasonable. FERC affirmed the prospective nature of the shift in valuation methodology, noting that because the gravity methodology had been approved by FERC, the TAPS Carriers were justified in relying on it until it was changed. 1993 Order, 65 F.E.R.C. p 61,277 at 62,291-92. According to the Commission, the retroactive application of the assay methodology would violate the filed rate doctrine. Id. at 62,292.
