9. 9 The prioritization process: A cyclical process Communication Prioritization Tracking and Execution Gathering customer requests and reporting timelines and status June 2007 thru January 2008 In-depth analysis, specifications, development, testing, training, etc. Getting customer priorities and evaluating available and needed resources

10. 10 Follow-up from issues reported at previous customer meeting Case sensitivity in the package field –Resolved. All our systems use uppercase. Request for contract number 01000 = 1000 –Resolved. All characters are an element of a contract number, no change made. Some customers cannot open shipper cut reports on a Blackberry –Resolved. Worked with impacted customers. Will work with others as needed.

11. 11 Follow-up from issues reported at previous customer meeting Customer gets kicked out of CIG Xpress too often –High priority for corporate IT to monitor and resolve. Changing nominations or confirmations in Pool Confirmation screen doubles certain data –Still unable to reproduce; need customer volunteers to help.

12. 12 Current Customer Requests

13. 13 1. APAL Payback Noms Streamline the online APAL Payback Process. Provide easier date entry, etc. Current Process: When entering a payback APAL (Receipt or Delivery Location of PBR, PBD or APL), the shipper is required to enter the APAL contract number, with the month of imbalance appended, in the upstream or downstream contract field. Effort Required: Medium

14. 14 1. APAL Payback Noms (cont.) Streamline the online APAL Payback Process. Provide easier date entry, etc. Requested Process: When entering a APAL Payback nom (Receipt or Delivery Location of PBR, PBD or APL) the customer would be given options for an easier method of entering correct data in the Upstream Contr or Downstream Contr fields.

15. 15 2. Copy Option Provide a copy option at the One Receipt One Delivery level to enable customers to copy and change fields for a new nomination. Requested Change: Add a Copy button to the Transportation Nominations Pick List screen which would copy the selected nomination to the Transportation Nomination Route screen, allowing fields to be modified and saved. Effort Required: Low

16. 16 3. DUNS Numbers Add process to autopopulate DUNS numbers associated with up and down contracts on a nomination. New process would populate the Up and Down DUNS when tabbing through the DUNS field in the nomination entry screens. The DUNS numbers would be learned from nominations at the beginning of the month and maintained by CIG schedulers. Effort Required: High

17. 17 4. Flow Day Diversions (FDD) Enable customers to request and schedule diversions online when they need to change a supply or market point after it has been scheduled without having to contact a scheduler at CIG. Requested Process: Create a Flow Day Diversion process allowing shippers to change the receipt location or the delivery location for cycles 2, 3 and 4 for any contracts with quantities scheduled in a previous cycle (1, 2 or 3). The resulting FDD quantities would be handled during the scheduling process as if they had been scheduled in the previous cycle. Current Process: When shippers want to change a supply or market point after a transaction has been scheduled, it is perceived as a new transaction in the next scheduling cycle. Effort Required: High

18. 18 5. HEEN Upload Add HEEN transactions to proprietary file upload. Requested Process: Modify the current Xpress Transport Nominations Upload process to accept HEEN transactions. Current Process: There is no process to allow HEEN transactions to be uploaded into Xpress. Effort Required: Medium

19. 19 6. Mismatch Correction Allow CIG schedulers to correct mismatched nominations after the nomination deadline. The issue: When there are mismatches of certain data fields in nominations for a given cycle, the quantity scheduled for that cycle is zero. In these cases, shippers are unable to correct the issue until the next cycle and the corrected nom is perceived as a new transaction in the next scheduling cycle. Effort Required: Medium Requested Process: Provide CIG Schedulers the ability to edit mismatched nominations after close of nominations. This process would not be for errors in quantity, only for contract number, package ID or DUNS number.

20. 20 7. NNT Overrun Requests Enable the customers entering requests for NNT overrun to select new contracts when their requests involve the subsequent month. Current Process: Only current month contracts are displayed in the drop down list even when Flow Dates span into the next month. If a new NNT contract is added effective the first of the following month, it is currently not displayed on the drop down list until the Flow Dates displayed are all in the following month. In this example, NNT contract 31053000, effective 1/1/2008, does not show as an option. Effort Required: Low

21. 21 7. NNT Overrun Requests (cont.) Enable the customers entering requests for NNT overrun to select new contracts when their requests involve the subsequent month. Requested Process: When a Flow Date in the next month is displayed, include contracts that become effective that month in the drop down list. Once all Flow Dates have moved into the next month, remove all contracts that are no longer in effect from the drop down list.

22. 22 8. Pool EPSQ Enforce EPSQ requirements through pooling nominations. Current Process: The location pool confirmation screens do not enforce EPSQ in cycles 3 and 4. Effort Required: High

23. 23 8. Pool EPSQ (cont.) Enforce EPSQ requirements through pooling nominations. Requested Process: Enforce EPSQ by applying these concepts: The pooling confirmation for an individual supply or market transaction would not be allowed to be decreased below EPSQ. During pool balancing, the lowest ranked entry would be reduced first to only what EPSQ criteria will allow. If additional balancing is necessary the next lowest ranked entry would be considered (also limited by EPSQ) … and so on until pool balancing is accomplished.

24. 24 9. Pool-to-Pool Nominations Enable customers to nominate Pool-to-Pool transactions at the headstation pool locations. Effort Required: Medium More information from customers is needed to fully understand this request.

25. 25 10. Reduction Reason Codes on Pooling Nominations Current Process: Reduction Reason Codes are not consistently populated throughout the pooling nomination process. Display reduction reason codes consistently across the transaction stream through the pooling nominations. Requested Process: Display Reduction Reason Codes consistently throughout the pooling nomination process. Effort Required: Medium

26. 26 11. Reinstatement Process Current Process: In cases where there are multiple constraints during one scheduling day, the scheduling process used by CIG leaves unused capacity on the pipe if transactions are impacted by both constraints. Add Reinstatement to the Capacity Allocation process to optimize throughput. Requested change: A change would be made to reinstate certain transactions during the scheduling process. Because there are several possible methods of doing this, as a part of the analysis process, we will need to gather customer input on how this should work. Effort Required: High

27. 27 12. Simplify Screens Improve navigation of Xpress, including consolidation of buttons and screens, limiting drill downs and enhance logical flow. Please submit the screens that would be most beneficial for you to have changed. Effort Required: Medium

28. 13. Nominations on Confirmation Screens Currently nominations are not visible until the cycle is open for confirmations Show requests after the nomination period is closed and before the confirmation period is open. Requested Process: Show requests after the nomination period is closed and before the confirmation period is open Effort Required: Medium

29. 29 14. EBB Enhancement Requested change: Show and store both Prelim and Final numbers on EBB Operationally Available Capacity. Effort Required: Medium

30. 30 15. Flow Day Information Report (cont.) Flow Day Information Report Enable customer to print a Flow Day Report with Reduction Reason Codes directly from the Flow Day Information screen.

31. 31 16. Interconnect Operator Confirmations Report Current Process: Provide more readable Interconnect Operator Confirmations Report for email distribution. Requested Process: The current Interconnect Operator Confirmations Report is not compatible with some customer email programs. The Interconnect Operator Confirmations Report would be redesigned to become accessible via more email and document software programs. Effort Required: Medium

32. 32 17. Report Enhancements Location Pool Balancing Report Add reduction reason codes to the Location Pool Balancing Report and to the Contract Routes Report. Effort Required: Medium

33. 33 17. Report Enhancements (cont.) Contract Routes Report Add reduction reason codes to the Location Pool Balancing Report and to the Contract Routes Report.

34. 34 18. Maintenance Notices Current Notice: Add min/max percentages of cut information to maintenance notices to help firm shipper calculate the impact. Requested Notice: 17. Mocane Compressor Station (MOC): One unit will be out of service [Month day] through [Month Day]. Capacity through MOC will be reduced from 50.0 to 24.0 MMcf/d. 17. Mocane Compressor Station (MOC): One unit will be out of service [Month day] through [Month Day]. Capacity through (MOC) will be reduced from 50.0 to 24.0 MMcf/d. Firm shippers should expect cycle 1 reductions of up to approximately 40% of their entitlements at MOC. Effort Required: Medium Assumption in the example above: MOC has a total of 40.0 MMcf/d of firm transport subscribed. This means that a reduction from 40.0 to 24.0 is a reduction of 16.0 MMcf/d … or a 40% reduction).

35. 35 19. Notice Subscription Options Requested change would allow shippers to subscribe to specific types of notices (Critical, Non-Critical) Add option to enable customers to subscribe to Critical Notices, Non-Critical Notices or both. Effort Required: Medium

36. 36 20. Hide Zero Quantities in Pooling Screens Allow customers the option to hide transactions with zero quantities on the Location Pooling Confirmations screen. Current Process: There is no way to hide zero quantities on the Location Pool Confirmations Screen. Effort Required: Low

37. 37 20. Hide Zero Nominations (cont.) Enable customers to hide zero quantities on the Location Pooling Confirmations Screen. Requested Process: Add Supply and Market side check boxes to hide zeros if both the Shipper Quantity and the Pooler Quantity are zero.

38. 38 21. HEEN Daily Detail Report Effort Required: Medium Create a report that provides a detailed listing of HEEN activity for a given day. Requested Report:

39. 39 22. Interconnect Operator Reduction Report Create a report to display all transactions for locations having reductions. Requested Report: Effort Required: Low
