Because of changes in Intermountain's gas related costs, as described more fully in ths Application, Intermountain's earngs wil not be decreased as a result of the proposed decrease in prices and revenues. Intermountain's curent rate schedules showing proposed changes are attached hereto as Exhibit No.1 and are incorporated herein by reference. Intermountain's proposed rate schedules are attached hereto as Exhibit No.2 and are incorporated herein by reference. Communcations in reference to this Application should be addressed to: Michael P. McGrath Director - Gas Supply & Regulatory Mfairs Intermountain Gas Company Post Office Box 7608, Boise, ID 83707 and Morgan W. Richards, Jr. Richards Law Office 804 East Pennsylvana Lane Boise, ID 83706 In support of this Application, Intermountain does allege and state as follows: APPLICATION - 2 I. Intermountain is a gas utility, subject to the jursdiction of the Idaho Public Utilities Commission, engaged in the sale of and distrbution of natual gas with 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. Intermountain provides natual gas service to the following Idaho communties and counties and adjoining areas: Ada County - Boise, Eagle, Garden City, Kuna, Meridian, and Star; Bannock County - Chubbuck, Inom, Lava Hot Springs, McCammon, and Pocatello; Bear Lake County - Georgetown, and Montpelier; Bingham County - Aberdeen, Basalt, Blackfoot, Firth, Fort Hall, Moreland/verside, and Shelley; Blaine County - Bellevue, Hailey, Ketchum, and Sun Valley; Bonneville County - Amon, Idaho Falls, Iona, and Ucon; Canyon County - Caldwell, Greenleaf, Middleton, Nampa, Parma, and Wilder; Caribou County - Bancroft, Conda, Grace, and Soda Springs; Cassia County - Burley, Declo, Malta, and Raft River; Elmore County - Glenns Ferr, Hammett, and Mountain Home; Fremont County - Parker, and St. Anthony; Gem County - Emmett; Gooding County - Gooding, and Wendell; Jefferson County - Lewisville, Menan, Rigby, and Ririe; Jerome County - Jerome; Lincoln County - Shoshone; Madison County - Rexburg, and Sugar City; Minidoka County - Heyburn, Paul, and Rupert; Owyhee County - Bruneau, Homedale; Payette County - Fruitland, New Plymouth, and Payette; Power County - American Falls; Twin Falls County - Buhl, Filer, Hansen, Kimberly, Murtugh, and Twin Falls; Washington County - Weiser. Intermountain's properties in these locations consist of transmission pipelines, a liquefied natual gas storage facility, distrbution mains, services, meters and regulators, and general plant and equipment. II. Intermountain seeks with this Application to pass though to each of its customer classes changes in gas related costs resulting from: 1) an increase in costs billed Intermountain due to higher prices charged by Northwest Pipeline GP ("Northwest" or "Northwest Pipeline") offset by a small decline in contract volumes on Northwest, 2) an increase in costs from Intermountain's APPLICATION - 3 "upstream" Canadian pipeline suppliers, 3) a decrease in the Company's projected costs relating to its storage contracts, 4) a decrease in Intermountain's Weighted Average Cost of Gas, or "WACOG"; 5) an updated customer allocation of gas related costs pursuant to the Company's Purchased Gas Cost Adjustment ("PGA") provision, 6) the inclusion of temporar surcharges and credits for one year relating to gas and interstate transportation costs from Intermountain's deferred gas cost accounts, and 7) benefits included in Intermountain's fi transportation and storage costs resulting from Intermountain's management of its storage and firm capacity rights on pipeline systems. Intermountain also seeks with this Application to eliminate the temporar surcharges and credits included in its curent prices durng the past 12 months, pursuant to Order Nos. 30649 and 30676 per Case Nos. IN-G-08-03 and INT-G-08-04. The aforementioned changes would result in an overall price decrease to Intermountain's customers. These price changes are applicable to service rendered under rate schedules affected by and subject to Intermountain's PGA, initially approved by this Commission in Order No. 26109, Case No. INT-G-95-1, and additionally approved through subsequent proceedings. Exhibit No. 3 contains pertinent excerpts from pipeline and related facilities' tarffs. Exhibit No. 4 sumarzes the price changes in: 1) Intermountain's base rate gas costs and its rate class allocation, and 2) adjusting temporar surcharges or credits flowing though to Intermountain's direct sales customers. Exhibit Nos. 3 and 4 are attached hereto and incorporated herein by reference. III. The curent prices of Intermountain are those approved by ths Commission in Order Nos. 30649 and 30676 per Case Nos. INT -G-08-03 and INT -G-08-04. IV. Intermountain's proposed prices incorporate all price changes impacting Intermountain's firm interstate transportation capacity including, but not limited to, any such changes implemented by Northwest and TransCanada's Pipelines which have occured since Intermountain's PGA filing in Case No. INT-G-08-03. Intermountain delivers transported natual gas to its Idaho Citygates via capacity leased from Northwest. Effective Januar 1, 2009, Northwest increased its rates to adjust for the higher APPLICATION - 4 number of leap year days included in its 2008 prices which, in tu, increased Northwest's 2009 full-rate capacity costs. In Case No. INT -G-08-03, Intermountain included the cost of incremental Northwest capacity which became effective November 1, 2008. The Company proposes to recover the additional cost resulting from including that same capacity for a full twelve (12) months (i.e. one additional month). Additionally, and pursuant to the contractual terms of an existing contract held by the Company on Northwest, a slight decline in the daily contracted volume on Northwest's system resulted in a decrease to the anual capacity costs charged to the Company. Also, Northwest's aforementioned leap year related price change increased the annual cost of the Company's capacity priced at a discount to (or indexed to) Northwest's full rate costs. These discounted, or indexed, contracts provide $5.4 milion in savings when compared to the otherwise full-rate cost. Intermountain also transports natural gas sourced from Alberta utilizing pipeline capacity on TransCanada's Foothils Pipeline system ("Foothills") and its Alberta system (also known as Nova Gas Transmission or "Nova") for ultimate delivery into Northwest. Both pipelines placed new rates into effect on Januar 1, 2009 resulting in an anualized increase for Nova capacity and a parially offsetting decrease at Foothils. Additionally, a contract held by the Company on the Nova pipeline expired on November 1, 2008 which results in a slight decrease to the cost incured on this pipeline. Intermountain formerly leased capacity at a Canadian storage facility known as Aeco. Aeco proposed a significant cost increase to renew the contract which caused the Company to re~ evaluate the cost-effectiveness of this facility. Intermountain determined that abundant gas supplies and suffcient market liquidity in Alberta would provide the necessar winter delivery securty at a lower cost to Intermountain's customers. Therefore, the Company determined the most economic course of action was to allow the contract to expire on March 31, 2009, thereby lowering Intermountain's fixed storage costs. Intermountain continues to utilize storage capacity at Questar Pipeline's Clay Basin storage facility and also proposes to pass back to its customers a decline in cycling fuel costs at Clay Basin reflecting the lower market price of natural gas. Intermountain continues to effectively manage its natural gas storage at Northwest's Plymouth LNG and Jackson Prairie facilities and Questar Pipeline's Clay Basin facility. Line 19 APPLICATION - 5 of Exhibit No.4, CoL. (h), contains over $2.2 milion in savings from the management of these assets which include the benefits generated from certain asset management agreements with third paries. Exhibit No.4, Lines I through 19, details the proposed changes in Intermountain's prices resulting from the aforementioned adjustments to Intermountain's cost of storage, and interstate and upstream capacity from its varous suppliers. V. The W ACOG reflected in Intermountai's proposed prices is $0.49600 per therm, as shown on Exhibit No.4, Line 21, CoL. (t). This compares to $0.67482 per therm curently included in the Company's tarffs. Driven by the downtur in our regional and national economy, weather adjusted demand for natual gas has diminished while, at the same time, natual gas supplies are plentifuL. Ths curent imbalance between supply and demand has drven down the near term prices for natural gas. Adding to this fudamental decrease, the proposed W ACOG includes the benefits to Intermountain's customers generated by Intermountain's management of signficant natual gas storage assets whereby gas is procured durng the sumer season for withdrawal and use durg the winter when prices would otherwise be higher. Additionally, and in an effort to fuher stabilize the prices paid by our customers durng the upcoming winter period, Intermountain has entered into varous hedging agreements to lock-in the price for signficant portions of its underground storage and other winter "flowing" supplies. Intermountain believes that the W ACOG proposed in ths Application, subject to the effect of actual supply and demand, wil likely materialize durg the upcoming PGA period. Intermountain will employ, in addition to those natual gas hedges already in place for the high winter demand, cost effective financial instrents to secure those prices embedded within the filed WACOG when and if those pricing opportties materialize in the marketplace. However, liquidity in the market is sustained by contrar opinions and natual gas prices could indeed realize levels different from those included in this Application. Although curent commodity futues prices dictate the use of this $0.49600 per therm W ACOG, Intermountain continues to remain vigilant in monitorig natual gas prices and is commtted to come before this Commission prior to this winter's heating season with an Application to fuher amend these APPLICATION - 6 proposed prices, should forward prices materially deviate from the $0.49600 per thermo Timely natual gas price signals and the accounting for any cost differences brought about by changes in the natual gas market, facilitated through the use of the PGA mechansm, enhance our customers' ability to make timely and inormed energy use decisions and ensure they only pay the actual cost of such supplies. It is important to continue to alert our customers in a timely maner to impending changes before their winter natual gas usage is before them. By employing the use of customer mailings and varous media resources, Intermountain wil continue to educate its customers regarding the wise and efficient use of natual gas, billing options available to help our customers manage their energy budget, and pending natual gas unt price changes. VI. Pursuant to Case No. INT-G-08-03, Intermountain has included temporar surcharges and credits in its October 1, 2008 and November 15, 2008 prices for the pricipal reason of collecting or passing back to its customers deferred gas cost charges and benefits, as outlined in Case No. !N- G-08-03. Line 26 of Exhibit No.4 reflects the elimination of these temporar surcharges and credits. VII. Intermountain's PGA tarff includes provisions whereby Intermountain's proposed prices will be adjusted for updated customer class sales volumes and purchased gas cost allocations, pursuant to the Company's approved cost of service methodology. Intermountain's proposed prices include a fixed cost collection adjustment pursuant to these PGA provisions, as outlined on Exhibit No.5, Line 24. The price impact of this adjustment is included on Exhibit No.4, Line No. 27. Exhibit No.5 is attached hereto and incorporated herein by reference. VIII. Intermountain proposes to pass back to its customers the benefits generated from the management of its transportation capacity totaling $5.9 millon as outlined on Exhibit No.7. These benefits include those generated from the release of segmented portions of Intermountain's firm capacity rights on Northwest Pipeline and other non-segmented capacity releases on Nortwest Pipeline. Intermountain proposes to pass back these credit amounts via the per therm credits, as detailed on Exhibit No.7 and included on Exhbit No.6, Line 1. Exhibit No.'s 6 and 7 are attached hereto and incorporated herein by reference. APPLICATION - 7 IX. Intermountain proposes to allocate deferred gas costs from its Account No. 186 balance to its customers through temporar price adjustments to be effective durng the 12-month period ending September 30, 2010, as follows: 1) Intermountain has been deferrng in its Account No. 186 fixed gas costs. The credit amount shown on Exhibit No.8, Line 8, CoL. (b) of $741,556 is attbutable to a tre-up of the collection of interstate pipeline capacity costs, the tre-up of expense issues previously ruled on by this Commission, and mitigating capacity release credits generated from the release of Intermountain's pipeline capacity. Intermountain proposes to collect or pass back these balances via the per therm surcharges and credits, as detailed on Exhibit No. 8 and included on Exhibit No.6, Line 2. Exhibit No.8 is attached hereto and incorporated herein by reference. 2) Intermountain has been deferrg in its Account No. 186 deferred gas cost amounts of $12.7 millon, as shown on Exhibit No.9, Line 2, CoL. (b), attbutable to Intermountain's varable gas costs since October 1, 2008. Intermountain proposes to pass back ths balance via a per therm credit, as shown on Exhibit No.9, CoL. (b), LineA and included on Exhibit No.6, Line 3. Exhibit No.9 is attached hereto and incorporated herein by reference. 3) Intermountain has been deferrng in its Account No. 186 defered gas costs related to Lost and Unaccounted for Gas as shown on Exhibit No.9, CoL. (b), Lines 5 though 20. This deferral results in net per therm decreases to both Intermountain's sales and transportation customers, as illustrated on Exhibit No.6, Line 3. Exhibit No.9 is attached hereto and incorporated herein by reference. X. Intermountain has allocated the proposed price changes to each of its customer classes based upon Intermountain's PGA provision. A straight cent per therm price decrease was not utilized for the LV -1 tarff. No fixed costs are curently recovered in the tail block of Intermountain's LV -1 tarff. Absent the proposed change to the W ACOG and the Lost and Unaccounted for Gas recovery as included on Exhibit No.9, the proposed decrease in the LV-1 tarff is fixed cost related, and therefore, a cent per therm decrease relating to fixed costs was made only to the first two blocks of the LV -1 tarff. APPLICATION - 8 XI. Each block of the proposed LV-I, T-3, T-4 and T-5 tarffs include a unform cents per therm decrease to adjust for Lost and Unaccounted for Gas as detailed on Exhibit No.9, Lines 13 through 20, CoL. (b). The prices, including the proposed adjustment for each block of the T-3, T-4 and T -5 tarffs, which include the removal of existing temporar price changes, are outlined on Exhibit No.1, Page 1, Lines 21 through 32. XII. Exhibit No. lOis an analysis of the overall price changes by class of customer. Exhibit No. lOis attached hereto and incorporated herein by reference. XIII. The proposed overall price changes herein requested among the classes of servce of Intermountain reflects a just, fair, and equitable pass-though of changes in gas related costs to Intermountain's customers. XIV. This Application is filed pursuant to the applicable statutes and the Rules and Regulations of the Commission. This Application has been brought to the attention of Intermountain's customers though a Customer Notice and by a Press Release sent to daily and weekly newspapers, and major radio and television stations in Intermountain's servce area. The Press Release and Customer Notice are attached hereto and incorporated herein by reference. Copies of this Application, its Exhibits, and Workpapers have been provided to those paries regularly intervening in Intermountain's rate proceedings. XV. Intermountain requests that this matter be handled under modified procedure pursuant to Rules 201-204 of the Commission's Rules of Procedure. Intermountain stands ready for immediate consideration of this matter. APPLICATION - 9 WHREFORE, Intermountain respectfully petitions the Idaho Public Utilities Commssion as follows: a. That the proposed rate schedules herewith submitted as Exhibit No. 2 be approved without suspension and made effective as of October 1, 2009 in the maner shown on Exhbit No. 2. b. That this Application be heard and acted upon without hearng under modified procedure, and c. For such other relief as this Commission may determine proper herein.

Statement of Natures Reasons and Basis for the Filng On June 1,1997, Northwest began billng its customers for reservation and demand charges using daily rates.1 In accordance with the rate sheets in Northwest's tariff, these rates are based on a year with 365 days. For leap years the rates are computed on the basis of 366 days and, accordingly, on November 8, 2007 (Docket No. RP08-61), Northwest fied revised tariff sheets to reflect daily reservation rates computed on the basis of 366 days, effective for calendar year 2008. With Commission acceptance of the November 8,2007 filng, the daily reservation rates currently listed in Northwest's Tariff reflect a 366 day-year and need to be adjusted back to a 365 day-year. 179 FERC 1f 61,259 (1997) and 80 FERC 1f 61,124 (1997).
