Effective 28 Aug 2003

393.1012. Rate schedules, procedures to establish or change. — 1. Notwithstanding any provisions of chapter 386 and this chapter to the contrary, beginning August 28, 2003, a gas corporation providing gas service may file a petition and proposed rate schedules with the commission to establish or change ISRS rate schedules that will allow for the adjustment of the gas corporation's rates and charges to provide for the recovery of costs for eligible infrastructure system replacements. The commission may not approve an ISRS to the extent it would produce total annualized ISRS revenues below the lesser of one million dollars or one-half of one percent of the gas corporation's base revenue level approved by the commission in the gas corporation's most recent general rate proceeding. The commission may not approve an ISRS to the extent it would produce total annualized ISRS revenues exceeding ten percent of the gas corporation's base revenue level approved by the commission in the gas corporation's most recent general rate proceeding. An ISRS and any future changes thereto shall be calculated and implemented in accordance with the provisions of sections 393.1009 to 393.1015. ISRS revenues shall be subject to a refund based upon a finding and order of the commission to the extent provided in subsections 5 and 8 of section 393.1009.

2. The commission shall not approve an ISRS for any gas corporation that has not had a general rate proceeding decided or dismissed by issuance of a commission order within the past three years, unless the gas corporation has filed for or is the subject of a new general rate proceeding.

3. In no event shall a gas corporation collect an ISRS for a period exceeding three years unless the gas corporation has filed for or is the subject of a new general rate proceeding; provided that the ISRS may be collected until the effective date of new rate schedules established as a result of the new general rate proceeding, or until the subject general rate proceeding is otherwise decided or dismissed by issuance of a commission order without new rates being established.
