PROCEDURE
NOTICE OF COMMENT
DEADLINE
On September 16, 2002, A vista Utilities filed a Purchased Gas Cost Adjustment
(PGA) Application with the Commission for authority to place new rate schedules into effect on
November 1 , 2002 that will decrease its annualized revenues by approximately $10 million.
its Application is approved, Avista states that customer rates will decrease on average by 15.5%.
The Company has requested an effective date of November 1 2002. Avista provides natural gas
service to approximately 56 000 customers in northern Idaho. In this Notice the Commission
processes this filing under Modified Procedure and establishes a written comment deadline.
THE APPLICATION
YOU ARE HEREBY NOTIFIED that Avista requests this rate reduction to true-up
the differences between Avista s actual weighted average cost of gas (W ACOG) purchased and
the W ACOG embedded in rates that have been deferred since September 1999. The Company
has also deferred the revenue received from Cascade Natural Gas for the release of storage
capacity at the Jackson Prairie Storage Facility, various pipeline refunds or charges, and
miscellaneous revenue received from gas-related transactions.
W ACOG
YOU ARE FURTHER NOTIFIED that to incorporate these deferred costs and
credits into rates, A vista proposes to modify two rate schedules that will adjust the W ACOG and
the deferral surcharge. The Company advocates reducing the prospective natural gas cost
component (the W ACOG) included in the rates charged to customers by $0.14727 per therm to

NOTICE OF COMMENT DEADLINE
$0.33098. This reduction is the result of netting the W ACOG reduction of $0.14946 per therm
against the demand-related increase of$0.00219 per thermo
The chart below depicts gas prices for Avista s residential and small business
customers (Schedule 101) over the past five years. Assuming the deferral is fully recovered in
November 2003 and the W ACOG remains as proposed, the Commission Staff estimates a cost to
customers of $0.6323 per therm - which is reflected below as the estimated price of gas in 2003.
By comparison Natural Gas Monthly lists the year-to-date average price of natural gas delivered
to residential customers as $0.896 per therm in Idaho versus $0.732 per therm nationally.

Deferral Surcharge
YOU ARE FURTHER NOTIFIED that Avista also seeks to recover the previous
timing differences accumulated in the gas cost deferral account over the 12-month period of
November 2002 through October 2003 through a surcharge. When the last PGA filing was
approved by Order No. 28827 issued August 20, 2001 , the gas deferral account totaled
approximately $22.3 million and was to be collected over a two and a half year period. As
depicted on the graph below, Avista estimates the remaining balance to be $8.7 million as of
June 30, 2002 and expects it to be fully recovered by November 2003. The Company proposes
increasing Schedule 155's amortization rates to recover this amount. If approved, firm sales
customers on Rate Schedules 101 , 111 , and 121 (General, Large General and Commercial)

YOU ARE FURTHER NOTIFIED that Avista proposes that the large transportation
and interruptible customers (Schedules 131 , 132, and 146) be given the option of
receiving/paying their portion of the deferred gas costs either through a lump sum credit/charge
or through an amortization rate as set forth in the Company s tariffs. If these customers choose
the lump sum method, Avista proposes to adjust these billings' credits/charges by the amount of
interest that accumulates from the end of the test period used in this filing to the date of actual
settlement. The Company states that this proposal would clear out the small residual balances
related to interest charges that are carried forward between PGA filings for large customers.
YOU ARE FURTHER NOTIFIED that if the Application is approved, Avista states
that the Company s estimated annual natural gas revenue will decrease by approximately
$10 030 000 (15.5%). Avista estimates that the average residential customer using 75 therms per
month would see their monthly bill decrease by approximately $10.45 (14.8%). Larger
commercial customers would experience an average decrease between 16.4% and 17.3%, with
the higher decrease percentages due to lower base rates. Incorporating its proposed changes to
Rate Schedules 150 and 155 , Avista recommends the following annualized change in rates per
customer class:

reduction primarily reflects decreases in the cost of gas purchased for customer use and will not
affect its earnings as a result of the proposed decrease in prices and revenues.

rates is merely a proposal subject to public review and Commission approval.
