Re: Adv No. ADV 19-01-G
Dear Ms. Hanian,
Attached for filing with the Commission is an original and seven (7) copies of Avista
Corporation's, dba Avista Utilities' ("Avista" or "the Company"), proposed additions, revisions,
and deletions to the following tariff sheets, I.P.U.C No. 27:
The Company is requesting to cancel the following tariff sheets:
Aiittsra ,ffi
The proposed tariff revisions contained herein are the by-product of lessons learned from
the Enbridge pipeline incident (as explained fufther below), and are ultimately designed to clarify
the provisions applicable to intenuptible and transportation customers, and the curtailment
processes for all natural gas customers. These changes are consistent with Idaho Statute Title 61,
Chapter 5, Section 6l-531, requiring Avista to submit a plan for the curtailment of gas
consumption to the ldaho Public Utility Commission.
The Company requests that the proposed revisions to the tariff sheets listed above become
effective September 27, 2019.
Background
On October 9,2018, a rupture occurred on a natural gas transmission pipeline owned and
operated by Enbridge. The rupture ignited at the site, north of Prince George, B.C. This event
caused Avista to activate the Company's emergency operations plan to address the shortage of
natural gas within the Pacific Northwest. Several of Avista's Oregon customers were curtailed
the day after the event in order to maintain the integrity of the Company's natural gas distribution
system. All customer curtailments were lifted on October 11,2018, two days after the incident.
After conducting an "after action" debrief ofthe Company's response to the event, Avista created
a cross-function team of employee's to address areas for improvement, process opportunities,
and communication related to its curtailment procedures and associated tariffs. The proposed
tariffs are a result of this teams efforts to clariff and streamline the Company's curtailment
process.
Summarv of Changes
As noted earlier, the proposed changes are a product of lessons leamed from the Enbridge
pipeline incident. The following is a high-level summary of the revisions for clarification in the
tariffs identified by Avista's cross-function team. Avista has also provided several strikethrough
and underlined tariffs as attachments to this filing in order to highlight the changes.
Moved the terms and conditions listed in transportation natural gas schedule 146 to a new
Schedule l8l, "Natural Gas Transportation Service Terms and Conditions." This change is
consistent with the Company's other jurisdictions and will make it easier to manage the terms
and conditions consistently in a single schedule, rather than managing them in separate
transportation schedules.
a
2
a Revised the terms and conditions in the new Schedule 181 as follows:
o Reorganized the schedule into sections;
o Added a definitions section where all terms related to the transportation of natural
gas are defined;
o Removed redundant language;
o Revised entitlement and balancing conditions to better align with the requirements of
natural gas transmission pipelines; and
o Updated provisions related to customers moving to, or from sales service schedules
and transport schedules, and vice versa, with an emphasis on making it easier for
customers to return to sales service schedules from transport schedules.
a Revised Schedules l3l and 132, Interruptible Service, to ensure the tariff language is
consistent with the terms and conditions applicable to transportation customers.
o Removed curtailment penalty language and made reference to Schedule 182, Plan for
Natural Gas Service Curtailmentl. and
o Made backup generation a recommendation, not a requirement.
The following are revisions to the Company's Schedule 182:a
o Updated the name of the Schedule to, "Plan for Natural Gas Service Curtailment";
o Clarified the process by which the Company would cuftail customers in the event
curtailment is eminent, including curtailing customers by their schedule instead of by
amount ofusage;and
o Increased the curtailment penalty from $l per therm to $10 per therm. This is
consistent with other utilities in the state of Washington and is intended to motivate
customers to quickly curtail their usage of natural gas.
In conclusion, Avista respectfully requests the Commission approve the proposed tariff
changes with an effective date of September 27,2019. The Company believes the terms and
conditions for interruptible and transportation customers are clearer and the process for
cuftailment has been more defined allowing for greater operational flexibility. These changes
will enable the Company to more effectively manage complex events as they unfold, as well as
limit the number of customers curtailed.
The Company has provided notice to affected customers due to requesting an increase to
the curtailment fee. A copy of the customer notice is attached to this filing as Appendix A.

Thankfully, events like the Enbridge incident are rare, however, if an event such as this
does arise, the proposed tariff language should make the curtailment process easier to navigate
for Avista employees and customers alike. If you have any questions regarding this filing, please
contact Garrett Brown at 509-495-2733, or myself at 509-495-4975.

Avista shall have no liability nor be considered in breach or in defuult for delay in performance
due to an event of Force Majeure. ln the event of a Force Majeure event, the time for
peformance shall be extended by a period of time reasonably neces$ary for Avista to
overcome such delay in performance. Nothing contained in this tariff shall require Avista to
settle any strike, lockout or other labor dispute.
TERMS AND GONDITIONS:
Customer Notifications: Avista will aftempt to provide notification of Curtailment to the
authorized representative(s) designated by the Customer two (2) hours prior to each
Curtailment. However, Avista reserves the right to issue an immediate Curtailment at the
Company's sole discretion. Each notification of Curtailment will specity the reason for the
Curtailrnent; the service address to which the Curtailment applies; and the quantities of each
particular service to be Curtailed.
Avista will provide annual notifications to all lnterruptible Sales Seruice and Transportation
Service Customers to confirm their emergency contact information. lf changes occur more
frequently, the Customer shall contact Avista to update Customeds emergency contact
information, including the name(s), telephone number(s) and email address(es) of the
Customer's authorized representative(s). The Customer may not designate an Agent as the
sole emergency contact,
ln the event Aviste is unable to provide notice of Curtailment - either because a Customer's
authorized emergency information on record is not current, or because the Company is unable
to reach any of the named authorized emergency contacts on record - all natural gas used by
the Custorner within the Curtailment Period will be considered unaulhorized usage, and the
Customer will be responsible to pay the fees as set forth in this schedule.
Unauthorized Usage: Customers shall be obligated to limit natural gas us€ to the quantities
permitted under the notification of Curtailment, and shall be responsible to take whatever steps
are necessary to reduce or discontinue their natural gas usage to the level required. Any natural
gas used in excess of the quantity permitted shall be deemed to be unauthorized. Customer
shall pay for unauthorized usage at the rate specified in this schedule, in addition to all other
charges applicable for the period in which the unauthorized quantity was used. ln no event shall
a Customer's payment for unauthorized usage be construed as Avista giving the Customer
permission to continue to use natural gas.
Avista retains the right to physically Curtail service to the meter of any Customer that is
consuming unauthorized quantities of natural gas. lf the Customer receives both natural gas
sales service and transportation service through the same meter, such physical shut off will
stop the flow of all natural gas.

PLAN FOR NATURAL GAS SERVICE CURTAILMENT - contanued
lf a customer purchases natural gas on more than one schedule (i.e,, Schedule 131 or 146 and
Schedule 112), they will be Curtailed in the order specified above for the quantities purchased
on each Schedule they are served on.
Notwithstanding the priorities listed above, the Company is not required to Curtail service to
any Customer(s) that the Company, in its sole judgement and discretion, determines will not
contribute to alleviating the supply or distribution capacity constraints. Further, for each of the
priorities listed above, the Company will endeavor to Curtail the fewest number of customers
as possible.
The Cornpany is not required to restore service or permit the use of natural gas simultaneously
to all Custorners on a Schedule that has been Curtailed if it believes doing so will affect the
safety, performance, integrity, reliabllity and/or system stability of its natural gas distribution
system, or otherwise affect service to higher priority Customers. Senrice may be restored to
any or all Customers on any schedule incrementally, to allow the Company an opportunity to
establish safety, performance, integrity, reliability and/or system stability, or otherwise manage
its supply and/or dlstribution system. ln the event it should becorne neces$ary to Curtail firm
seruice due to force majeure conditions, Avista may Curtail firm service without reference to
the priorites established herein.

7. For customers with annual usage greater then 250,000 therms, the
prorated share of deferred natural gas costs will be determined for individual
customers served under this Schedule who disconnect service or switch to a
transportation sales schedule. Disconnect service would include but not be limited to
customers who close their business or switch entirely to an alternative fuel. The
deferred natural gas cost balance for each Customer will be based on the difference
between the purchased gas costs collected through rates and the Company's actual
purchase gas cost multiplied by the Customer's therm usage each month. The
deferred natural gas cost balance for Customers who switch from this schedule will be
transferred with the customer's account. The Customer shal! have the option of 1) a
lump-sum refund or surcharge to eliminate the deferred natural gas cost balance, or
2) an amortization rate per therm for a term equal to the deferral recovery period to
reduce the deferred natural gas cost balance prospectively provided the Customer
has not discontinued service. The Customer's share of deferred natural gas costs
incurred since the last Purchase Gas Cost Adjustment is subject to a true-up for any
modifications made by the Commission in the next Purchase Gas Cost Adjustment. lf
the amount billed is different than the Commission approved amount, Avista will bill or
refund the Customer the ditference between their share of the approved amount and
the amount previously billed to the Customer.
