Applicant's current rate schedules, showing proposed changes for permanent rates, are attached hereto as Exhibit A and are incorporated herein by reference. Applicant's proposed permanent rate schedules are necessary due to an increase in Applicant's cost of service and are attached hereto as Exhibit B and incorporated herein by reference. Communications in reference to this application should be addressed to: Wal ter H . Smith, Pres ident Intermountain Gas Company 555 South Cole Road Boise, Idaho 83705 and APPLICATION - 1 I I I I I I I I I I I I I I I I I I I I I I Eugene C. Thomas, Esq. T. N. Ambrose, Esq. MOFFATT, THOMAS, BARRETT & BLANTON CHARTERED Post Office Box 829 Boise, Idaho 83701 In support of this application, Applicant alleges: I. Applicant is a public utility engaged in the sale and distribution of natural gas within the state of Idaho under authority of Commission Certificate No. 219 issued December 2, 1955, as amended and supplemented by Order No. 6564 dated October 3, 1962. Applicant's Articles of Incorporation, as amended, are on file with the Commission in Case No. U-I034-67 and are incorporated herein by reference. No changes have been made to said Articles of Incorporation since they were filed in that case. II. Applicant provides natural gas service to the following Idaho counties and communi ties: Ada County - Boise, Garden City, Kuna and Meridian¡ Bannock County - Chubbuck, Inkom, Lava Hot Springs, McCammon and Pocatello¡ Bear Lake County - Georgetown and Montpelier¡ Bingham County - Aberdeen, Basalt, Blackfoot, Firth and Shelley¡ Blaine County - Bellevue, Hailey, Ketchum and Sun Valley¡ Bonneville County - Amon, Idaho Falls, Iona and Ucon ¡ Canyon County - Caldwell, Middleton, Nampa and Parma¡ Cassia County - Burley and Declo¡ Caribou County - Bancroft, Grace and Soda Springs¡ Elmore County - Glenns Ferry and Mountain Home¡ Fremont County - Parker and St. Anthony¡ Gem County - Emmett¡ Gooding County - Gooding and Wendell ¡ Jefferson County - Lewisville and Rigby¡ APPLICATION - 2 I I I I I I I I I I I I I I I I I I I I I I Jerome County - Jerome ¡ Lincoln County - Shoshone ¡ Madison County - Rexburg and Sugar City¡ Minidoka County - Heyburn, Paul and Rupert¡ Owyhee County¡ Payette County - Fruitland, New Plymouth and Payette¡ Power County - American Falls¡ Twin Falls County - Buhl, Filer, Hansen, Kimberly,Murtaugh and Twin Falls¡ Washington County - Weiser. Applicant's properties in these locations consist of transmission pipelines, a compressor station, a liquefied natural gas storage facility, distribution mains, services, meters and regulators, and general plant and equipment. III. Applicant purchases its natural gas from Northwest Pipeline Corporation ("Northwest") at rates established by Northwest and approved by the Federal Energy Regulatory Commission. iv. The current rates of App licant are those approved by this Commission in Applicant's last general rate case pursuant to Commission Order No. 17078 in Case No. U-I034-95, as modified by Order No. 16976 in Case No. U-I034-98 and as modified by Order No. 17202 in Applicant's last gas purchase cost tracking proceeding in IPUC Case No. U-I034-100. No other Commission action has been taken or sought relative to Applicant's existing and proposed rates. v. App licant has adopted a test period ending Ju ly 31, 1982, adjusted for known and measureable changes, in order to APPLICATION - 3 I I I I I I I I I I I I I I I I I I I I I I determine its earnings deficiency. The proposed rate base has been calculated in the manner adopted by this Commission in Order No. 17078. VI. A 11.645 percent overall rate of return is required to attract the capital necessary to meet Applicant's construction program, mandatory sinking fund requirements and refinancing requirements and to allow Applicant the financial strength necessary to meet its statutory duty to provide service to its customers. VII. Applicant's present rates do not permit recovery of its costs and a reasonable return on invested capital and are therefore no longer fair, just and reasonable. App licant cannot afford to absorb or defer any part of the increase proposed in this application without impairing its financial ability to render the utility service to its customers required by law. In order to avoid a confiscatory rate level, to achieve fair and equitable rates, and to ensure that Applicant remains able to provide utility service to its customers, it is necessary that Applicant increase its current rates to produce additional annual revenues of $10,097,617. Such amount is the minimum required to assure service to App licant' s customers as required by law and to avoid further impairment of Applicant's credit and financial standing. Exhibit C, attached hereto and incorporated by reference, compares the revenues generated by App licant' s current rates to those generated by Applicant's proposed permanent rates . APPLICATION - 4 I I I I I I I I I I I I I I I I I I I I I I VIII. Applicant does propose modifications to its current rate design, with the exception of Rate Schedule T-L. These changes are required in order that rates for different classes of Applicant's customers be more closely based on the cost of service to those classes. The effect of the proposed changes are shown on Exhibit C. ix. Applicant proposes a modification in its current General Service Provisions in order to incorporate a Revenue Stabilization Clause proposed in this application. A copy of the proposed modification is attached as Exhibit D. x. Applicant's current rates are unfair, unjust, unreasonable and confisccltory and do not allow Applicant to earn a sufficient return on investment or to provide the service to its customers mandated by law. Applicant's proposed rates are fair, just, reasonable and sufficient and would allow Applicant to earn a fair return on its investment and provide the service to its customers required by law. Xi' Filed with this application is the direct supporting testimony and exhibits of Walter H. Smith, Reed Penning, V. Dale Blickenstaff, Russell L. Worthan, Jeffrey K. Lebens, Greg Conlon, Randy L. Schultz, Thomas R. Brown, Susan Koehler Kennedy, and N. Charles Hedemark. APPLICATION - 5 I I I I I I I I I I I I I I I I I I I I I I XII. Applicant has brought the filing of this application to the attention of its customers by letter to its large volume contract customers and press releases to all news média in its service area. A copy of this application, with exhibits, testimony and supporting workpapers, will be provided to all of the intervenors in Applicant's last general rate case. A copy of this application, with exhibits, is on file in each of Applicant's offices and is available for public review during normal business hours. APPLICATION - 6 I I I I I I I I I I I I I I I I I I I I I I WHEREFORE, Applicant petitions the Idaho Public Utilities Commission for relief as follows: 1. That this application be heard and acted upon at the earliest possible date. 2. That Applicant be permitted to increase its rates immédiately and permanently in an amount sufficient to produce additional annual revenues Of $10,097,617 pursuant to the proposed rate schedules submitted herewith as Exhibit B. 3. That this Commission rule that a hearing for clarifying questions be replaced with discovery pursuant to the Idaho Rules of Civil Procedure. 4. For su ch other and further relief as the Commission deems proper. DATED this 30th day of April, 1982. INTERMOUNTAIN GAS COMPANYBY~ Walter H.

REVENUE STABILIZATION CLAUSE 20.1 Applicability. This Revenue Stabilization Clause applies to all rate schedules contained in Second Revised Volume No.1 of this IPUC Gas Tariff. It specifies the procedures to be utilized in adjusting rates applicable under each such rate schedule in order to reflect changes in the average Gross Margin on a uniform cents per therm basis for ratemaking purposes for sale and delivery under such rate schedules. As used herein, the terms "Gross Margin" shall represent all those costs included in the total cost of service including the "cost of capital" but excluding charges reicorded in IPUC Account Nos. SOO, SOL, S02, S03, S04, .S05, S06, SOS and S09 and the City Franchise Tax charges recorded in IPUC Account No. 40S. 20.2 Base Tariff Rates. The Base Tariff Rate Schedule applicable to each schedule contained in Second Revised Volume No. 1 of this IPUC Gas Tariff is identified on Sheet No. 3A hereof. 20.3 Currently Effective Tariff Rates. Rates applicable to each rate schedule contained in Second Revised Volume No. 1 of this IPUC Gas Tariff shall be the Base Tariff Rates plus a surcharge as identified on Sheet No. 3A hereof. 20.4 Changes in Currently Effective Tariff Rates. Rates applicable to each rate schedule contained in Second Revised Volume No. 1 of this IPUC Gas Tariff include a surcharge as identified on Sheet No. 3A. The surcharge shall be adjusted on the Adjustment Dates identified in Section 20.5 below, for changes in the Gross Margin in accordance with the rate adjustment provision hereof to the end that the Company will be reimbursed for the actual costs. 20.5 Adjustment Date. The Adjustment Date shall be October 1 of each year. On such date, Company shall, in accordance with the rate adjustment provisions hereof, increase or decrease the surcharge applicable to each rate schedule contained in Second Revised Volume No. 1 of this IPUC Gas Tariff to reflect changes in the average Gross Margin. As so adjusted, the surcharge rate applicable to each rate schedule will be included on Sheet No. 3A (Second Revised Volume No.1) hereof as the Currently Effective Surcharge Rate. 20.6 Amount of Adjustment. The amount of adjustment to be made effective each Adjustment Date shall consist of the sum of a Gross Margin Adjustment and Surcharge Adjustment. The Gross EXHBIT D - Page 1 I I I I I I I I I I I I I I I I I I I I I I 20.7 Margin Adjustment shall consist of the net change in the annualized Gross Margin per Therm sold. The procedure for determining the Gross Margin Adjustment is set forth in Section 20.7 below. The Gross Margin Surcharge Adjustment shall consist of an amount necessary to recover or return the amount accumulated in the Unrecovered Revenue Stabilization Account including an appropriate amount of carrying charge. The procedures for establishing and maintaining the Unrecovered Revenue Stabilization Account and for determining the Gross Margin Surcharge Adjustment are set forth in Section 20.8 below. The Gross Margin Cost Adjustment and the Gross Margin Surcharge Adjustment shall be applied to all rate schedules contained in Company's IPUC Gas Tariff, Second Revised Volume No.1. Gross Margin Cost Adjustment. The Gross Margin Cost Adjustment per Therm sold shall be determined by dividing the net change in the annualized Gross Margin Cost, determined as specified below, by the amount of Therms delivered during the 12 months ending three months prior to the applicable Adjustment Date. The amount of net change in the annualized Gross Margin shall be calculated as follows: (a) The amount of net change in the annualized Gross Margin Cost for the purposes of this Section shall be the difference between the cents per Therm computed under (i) and (ii) below applied to the total Therms of gas delivered as defined in Section 20.7(b) below. (i) The annualized Gross Margin Cost for gas shall be that determined by the Commission in its most recent Order. The average Gross Margin Cost per Therm is then established by dividing the total Gross Margin determined by the Commission in the most recent order, as described above, by the total amount of Therms delivered as defined in Section 20.7 (b) below. (ii) The average Gross Margin Cost per Therm applicable to the currently effective tariff rates, as set forth on Sheet No. 3A of Second Revised Volume No. 1 of this IPUC Gas Tariff, and determined in Company's most recent filing under this Section 20. (b) Annual Therms to be Utilized: The amount of Therms to be utilized shall be that delivered as defined in Section 20.7 hereof during the twelve month period ending three months EXHIBIT D - Page 2 I I I I I I I I I I I I I I I I I I I I I I 20.8 20.9 prior to the applicable Adjustment Date; provided, however, that such quantities shall be subject to adjustment by Company to reflect annualization of new deliveries and significant changes in takes from existing delivery connections. Gross Margin Surcharge Adjustment. The Gross Margin Surcharge Adjustment per Therm delivered shall be determined by dividing the balance in. the Unrecovered Gross Margin Cost Account, defined below, at the end of the latest available month at the time of the computation being made under the provisions of this Section, by the amount of Therms estimated to be delivered under rate schedules .identified on Sheet No. 3A in this IPUC Gas Tariff, Second Revised Volume No. 1 during the twelve billing months that the Surcharge Adjustment will be in effect. Beginning as of the date this Gross Margin Cost Adjustment Provision becomes effective, Company shall establish and maintain an Unrecovered Revenue Stabilization Account. Entries shall be made eo this account each month as follows: (a) A debit entry equal to the difference between actual Gross Margin and the Minimum Gross Margin Cost as set forth on Sheet No. 4A (if the actual Gross Margin is less than the Minimum Gross Margin Cost) or a credit entry equal to the difference between actual Gross Margin and the Maximum Gross Margin Cost as set forth on Sheet No. 4A (if the actual Gross Margin is greater than the Maximum Gross Margin Cost). (b) A Credit entry equal to the Therms delivered during the month under rate schedules contained in this IPUC Gas Tariff, Second Revised Volume No. 1 and multiplied by the Surcharge Adjustment reflected in the rates charged during the month. (c) In each month the Unrecovered Revenue Stabilization Account shall be debited (if the balance in said account is a debit balance) and shall be credited (if the balance in said account is a credit balance) for a carrying charge which shall be determined by multiplying the balance in the account by 1/12 of the interest rate established for short-term borrowings as approved in the Company's last general rate case. Time and Manner of Filing and Related Reports. Company shall file each adjustment at least 30 days prior to the applicable Adjustment Date by means of a Revised Sheet No. 3A (Second Revised Volume No.1). Each such filing shall be accompanied by a report which shows the derivation of the adjustments to be applied. Such filing, including the report, shall be posted as defined by the Idaho Public Utilities Commission. EXHIBIT D - Page 3 I I I I I I I I I I I I I I I I I I I I I I -:C" oZ ..
