PART 3

GENERAL TERMS AND CONDITIONS

(Continued)

Any storage injection capacity remaining after

allocation to FSS storage shippers under this part will be

available for use in providing service under Rate Schedule

PAL1.

If any injection capacity remains after service to FSS

and PAL1 shippers, it will be allocated to ISS shippers, up

to the level requested, based on the inventory rate stated

in the ISS storage service agreement with the highest rate

being given the highest priority. When two or more shippers

are paying the same rate, available capacity will be

allocated pro rata up to the level requested, to those ISS

shippers that are paying the same rate. This procedure will

continue until (1) all the requests are filled, or (2) all

available injection capacity is utilized.

Any injection capacity remaining after allocation to

ISS shippers will be available for use in providing parking

and loaning service under Rate Schedule PAL2 with the

highest rate paid being given the highest priority. When

two or more PAL2 shippers are paying the same rate,

available capacity will be allocated pro rata up to the

level requested, to those PAL2 shippers that are paying the

same rate. This procedure will continue until (1) all the

requests are filled or (2) all available injection capacity

is utilized.

(b) Allocation of gas that can be withdrawn

daily from storage on a firm or interruptible basis during

the November 1 through March 31 withdrawal period shall be

calculated as follows:

FIRM WITHDRAWAL ALLOCATION = [(A/B)*(C-D)] + E

INTERRUPTIBLE WITHDRAWAL AMOUNT = [(K-C-M)+L]

A = FSS shipper's working gas remaining in storage

B = Total working gas remaining in storage for all FSS

shippers

C = Maximum possible reservoir deliverability

attributable to the sum of cushion and FSS

shipper's working gas inventory

D = Sum of FSS shipper's minimum required

deliverabilities

E = FSS shipper's minimum required deliverability
