Contracting Help
                        Entering correct rates on requests

                        Short Term Amendments Best Practices

                        Upcoming Enhancements

                        Additional Training

31   March 2, 2021
Rates and Rate Type
     Ensure your rates and rate types are correct
     Max Rate Contracts – no need to request discount at alternate point

32         March 2, 2021
Discounted Rates on Alternate Points
     Discounted points do not affect Priority of Service, they only ensure a discount is available to flexed nominations

33         March 2, 2021
Short-term Amendments
     Shippers can begin submitting amendments for the next month at 11am, 4 business
     days before the end of the month
     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.

                            We follow tariff guidelines of First Come, First Serve

34    March 2, 2021
How We Review Amendments
     1      We start with the available capacity
                         • If there has been no new contract prior to 11am, then this is the same capacity posted online

     2      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 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

35       March 2, 2021
Best Practices
                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

                How can shippers improve their odds?
                    Submit requests as soon as possible after 11am
                    Prioritize 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.

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

36      March 2, 2021
Things to Keep in Mind
                   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

                  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

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

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

      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
      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
      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.
