(h)Utilities with more than 50,000 full service customers shall file an application to include a GPIM within their GCA tariff sheets pursuant to rule 4607 within 60 days of the effective date of these rules. The initial GPIM for utilities with more than 50,000 but less than 500,000 full service customers shall be established in accordance with paragraph 4607(a). The initial GPIM for utilities with more than 500,000 full service customers shall be established in accordance with paragraph 4607(b). Once established by application, the utility shall implement a GPIM through their GCA filings. Modifications to a GPIM shall be accomplished through an application filing separate from a GCA filing.#

(i)No later than 90 days after the conclusion of a full heating season covered by the utility's initial GPIM, the utility shall file an application for the renewal of the GPIM. Implementation of the initial GPIM shall continue until the renewed GPIM goes into effect. For the utilities with an initial GPIM based on the framework set forth in paragraph 4607(a), the renewal application shall present an analysis of the implementation of the utility's initial GPIM as approved by the Commission and an analysis of GPIM benchmark gas rate and GPIM sharing amount in paragraph 4607(b) as if they had instead been implemented over the same period as the initial GPIM. The utility may propose to implement a modified GPIM provided that the Commission determines the modified GPIM comports with the requirements of § 40-3-120, C.R.S.#
