Section 525.10  Applicability

a)         The Gas Charge(s) shall be applied to all therms associated with the service classifications so identified in the filed rate schedules of all gas public utilities operating in the State of Illinois.  If a utility elects to establish separate Gas Charge(s) for recovery of costs of a seasonal nature, such Gas Charge(s) shall be applied to therms associated with the appropriate seasonal period.  The Gas Charge(s) shall be applied either to each therm billed during the effective month or to each therm delivered during the effective month.  The utility shall elect whether a billed or a delivered method shall be used, and such election shall remain in effect until a utility request to effect a change is approved by the Commission.  Each Gas Charge shall be determined in accordance with Section 525.60.

b)         The number and design of Gas Charge(s) applicable to a given service may differ between services.  For example, some services may include a single Gas Charge while other services may include separate commodity and non-commodity Gas Charges.

c)         Utilities shall report monthly, in a format designated by the Illinois Commerce Commission ("Commission"), the Gas Charge(s), calculated under the provisions of Section 525.60 to be applied to service rendered or billed during the effective month.  The reports required by this Section must be postmarked by the twentieth day of the filing month.  A monthly report postmarked after that date but prior to the first day of the effective month will be accepted only if it corrects an error or errors from a timely filed report for the same effective month.  Any other report postmarked after that date will be accepted only if submitted as a special permission request under the provisions of Section 9-201(a) of the Public Utilities Act [220 ILCS 5/9-201(a)].

d)         A utility shall reflect the requirements of this Part on the first day of the utility's reconciliation year that begins on or after January 1, 1996.  A utility implementing this Part after January 1, 1996, shall, from January 1, 1996, until the first day of its reconciliation year, file all tariffs pertaining to the utility's purchased gas adjustment clause in conformance with Section 9-201 of the Public Utilities Act [220 ILCS 5/9-201].
