of paragraphs (a) through (d) of this rule. With its submittal, the utility shall provide
cross-referenced and footnoted work-papers fully explaining the amounts shown in each
attachment.
(a) GPP attachment No. 1 - gas purchase schedule. This attachment shall provide a
forecast of the specific gas commodity supplies, segregated by receipt
point/area, which the utility plans to purchase in order to meet forecasted sales
gas demand during each month of the applicable gas purchase year.
(b) GPP attachment No. 2 - gas purchasing pricing description. For each specific
receipt point/area, this attachment shall provide an estimate of applicable ranges

the upcoming gas purchase year in order to meet sales gas and gas
transportation demand.

sources of capacity available to the utility, including forecasted upstream
services, forecasted gas commodity to be purchased directly into the
utility’s distribution system (i.e., city gate purchases) on a firm basis, and

(III) A comprehensive explanation of the utility’s forecasted level of planned
upstream service purchases.
(IV) Forecasted capacity release volumes and revenues for release of
