Contracting Help

Entering correct rates on requests

Upcoming Enhancements

Short Term Amendments Best Practices

Additional Training

March 2, 202132

Ensure your rates and rate types are correctMax Rate Contracts – no need to request discount at alternate point

Rates and Rate Type

March 2, 202133

Discounted Rates on Alternate PointsDiscounted points do not affect Priority of Service, they only ensure a discount is available to flexed nominations

March 2, 202134

Shippers can begin submitting amendments for the next month at 11am, 4 business days before the end of the month

We follow tariff guidelines of First Come, First Serve

We receive amendments throughout the month for the current month, but we receive multiple amendments requests by various shippers at 11am for amendments affecting the following month

We analyze all the amendments submitted together in a batch process because it helps us give shippers the most capacity. Unfortunately, this approval process is time consuming and can take several hours to complete.

Short-term Amendments

March 2, 202135

We start with the available capacity

• If there is enough available capacity, we accept the RFS• If there is no available capacity, we reject the RFS• If there is some available capacity, we provide shippers with

their options so they can submit a Copy Forward

We begin by analyzing the first RFS submitted (first in queue) and work our way through the queue to the last RFS submitted (last in queue)

• If there has been no new contract prior to 11am, then this is the same capacity posted online

How We Review Amendments

1

2

March 2, 202136

Unless you are shortening your path, there is no way to guarantee that you will get the capacity you’re requesting*

*Assuming there is ample MAP capacity

Submitting a request even ONE second after another shipper can impact the outcome for the request

How can shippers improve their odds?Submit requests as soon as possible after 11amPrioritize the order in which you submit your requests

Are you completely changing your path? If so, submit it first.Are you trying to extend your path through a constrained area? If so, submit it first.Are you just shortening your path on a contract? If so, submit it later.Are you amending an interruptible contract? If so, submit it last.

Best Practices

March 2, 202137

Things change from month to month. Just because a shipper’s amendment is approved one month, doesn’t mean it will be approved next month

• Starting capacity may be different• Other shippers can change their amendments• Other shippers may submit their requests earlier

An expanded version of this training is available at QuestarPipeline.com

No shippers can control any of the factors listed above• The best thing each shipper can do is get their requests in

quickly so that they are as high in the queue as possible

Things to Keep in Mind

March 2, 202138

Clock to be added on subsequent RFS screens

Microsoft AzureRecall/Reput notification to be sent to Replacement Shipper

Redesign of Locations and Alternate Points in Capacity Release screen

• similar to RFS grids

Upcoming Enhancements

We went live with the Citrix version, Questline, back in October 2009. The Citrix version had become cost prohibitive to maintain through ongoing support

Why did we change to a new web version of Quorum?

March 2, 202155

Old software

New functionality of a web-based version• Ability to log on with any device (PC, tablet and cell phone)• Continue working right where you left off• Dashboard (customize with the ability to add widgets)

What widgets do you like and what ones would you like to see? (Survey)

FAQ’s

March 2, 202156

Where can I find capacity availability for a cycle?Capacity postings are available at: https://www.questarpipeline.com

• Informational Postings – Capacity – Operationally Available

o Here you will find daily available capacity which follows the end of each cycle. Ending volumes include activity from the cycle such as cuts and allocations.

What points were constrained during the cycle in question?This can be found at: www.questarpipeline.com

• Customer Activities – Customer Support

o Scroll down, and on the right-hand side of the screen you will find “Constraint Points”, from there click on the pipeline in question to see up to date allocations.

FAQ’s

March 2, 202157

What do you do if you cannot see your nom from the Nomination Submission screen in the Nomination Maintenance screen?

• In nom submission, change any nominations that did not make it to nom maintenance by at least 1 dth. Balance all paths/ups/downs, then submit the nomination. If this does not work, call the scheduling hotline.

How can I tell where a cut was made?• The best way to verify where a cut originated is in Nom Maintenance.

In the path, select the nom in question. Either the Upstream or Downstream side will have CPR (Confirming Party Reduction) as the reason reduction code, along with EDI browser or the User ID of the person who made the cut. This is the location where the cut originated from, and the other side will have a PBL (Path Balancing) as the reason reduction code to balance out the nomination.

Thank you!
