GENERAL TERMS AND CONDITIONS

35.4. Calculation. The posted FGRP matrix categories will be

calculated as follows:

(a) Projected Monthly Compressor Station Factors. Projected

monthly compressor station gas use factors will be calculated for each

compressor station based on recent gas measurement data and nominated

transportation receipt quantities as follows:

Projected Compressor Station factor = C/MRC

C = Projected monthly compressor station gas use

MRC = Projected monthly compressor station transportation

receipt quantities

(b) Projected ML&U Factor. Projected miscellaneous

transmission system gas used will be based on recent gas measurement data for

gas quantities including, but not limited to, gas used to operate pipeline

equipment such as valves and heaters and blow downs not associated with

compressor stations. Projected lost, gained or unaccounted-for gas

quantities will be calculated by subtracting the physical transmission

deliveries, including actual system gas used, from corresponding physical

transmission receipts. The projected ML&U factor is calculated as follows:

Projected ML&U Factor = (MT + L&U)/MR

MT = Projected miscellaneous transmission system gas used quantities

L&U = Projected L&U quantities

MR = Projected monthly transportation receipt quantities
