UNBUNDLED SALES SERVICE

6. CURTAILMENT (continued)
Priority 7 Industrial requirements served under interruptible
contracts with customers who have agreed to purchase
at least a specified minimum volume of gas if it is
tendered to them.
Priority 8 Industrial requirements served under interruptible
contracts with customers who have not agreed to
purchase at least a specified minimum volume of gas if
it is tendered to them.
(c) Each higher priority of use will be fully protected from
curtailment until all lower priorities have been ordered curtailed
one hundred percent (100%); that is, no curtailments of Priority 5
uses will be ordered until all Priority 6 uses have been ordered
curtailed, and so forth.
(d) If supply availability permits only partial sales of gas to a
given category of use, curtailment will be effected, on the basis
of a pro rata sharing based on historical deliveries to customers
for that category. Historical takes will be calculated on the
basis of a three-year average taken from the three-year period
ending September 30, 1971. On days when curtailment is required,
total sales to individual customers may not exceed contract
volumes.
(e) Before service commences, when the character of gas usage
materially changes, and from time to time upon request, each
customer shall furnish Seller with all information reasonably
required by Seller with regard to gas usage at the facility served
to assist Seller in its determination of the proportionate parts,
if any, of that usage falling in different priority categories.
In determining the appropriate priority category for gas sold, no
distinction will be made between gas sold to direct customers and
to resale customers.
(f) Seller does not propose to curtail sales under its several
isolated jurisdictional field sales of gas. The wells covered by
the field sale contracts are not connected to Seller's own
pipeline systems and
