SFPP L.P. and AOPL had previously appealed the Federal Energy Regulatory Commission’s standard for finding “changed circumstances,” enabling the SFPP’s rates that were grandfathered under the Energy Policy Act to be reexamined. This month, AOPL and SFPP jointly filed an intervenor brief with District Court of Appeals covering the “changed circumstances” issue and the income tax allowance issue in the SFPP appeal. The shipper intervenors also filed their brief in this matter.
