Section 4 CCR 723-4-4603 - Gas Cost Adjustments
(a) A utility shall file an application to adjust its GCA. The GCA application shall be filed pursuant to the schedule provided in rule 4602. A utility shall file a GCA application not less than two weeks in advance of the proposed effective date.
(b) A GCA application shall include, in the following order and specifically identified, the following information, either in the application or in appropriately identified attachments:
(I) the information required by paragraphs 4002(b) and 4002(c); and
(II) the information required by rule 4604. Attachments 2, 3, 5 and 6 listed in rule 4604 shall be provided in written form and shall be provided electronically, in executable format with all cell formulas intact, using spreadsheet software that is compatible with software used by the Commission staff.
(c) If the projected gas costs have changed from those used to calculate the currently effective gas cost or if a utility's deferred gas cost balance increases or decreases sufficiently, the utility may file an application to revise its currently effective GCA to reflect such changes, provided that the resulting change to the GCA equates to at least one cent ($0.01) per Mcf or Dth.
(d) Applicability of the GCA. The GCA shall be applied to all utility sales gas rate schedules. A utility engaged in the provision of gas transportation service may calculate a GCA that may be applied to transportation gas rate schedules in order to reflect appropriate costs. Absent a Commission decision, a utility engaged in the provision of gas transportation service shall not be required to calculate a transportation GCA factor.
(e) Interest on under- or over-recovery. The amount of net interest accrued on the average monthly balance in Account No. 191 (whether positive or negative), is determined by multiplying the monthly balance by an interest rate equal to the Commission-authorized customer deposit rate for gas utilities. If net interest is positive, it will be excluded from the calculation of the deferred gas cost.
(f) Price volatility risk management costs (hedging). Costs related to gas price volatility risk management for jurisdictional gas supply may be included for recovery through the GCA, if allowed by tariffs or by Commission decision. Such costs are subject to the prudence review and standard provided in rule 4607.
(g) Calculation of the GCA. The GCA shall be calculated to at least the accuracy of one mil per Mcf or Dth pursuant to the following formula, subject to individual GCA rule variances granted by the Commission:

GCA = (current gas cost + deferred gas cost)- (base gas cost).
