A: The unpaid balances remaining at the end of the production month being billed can include amounts invoiced but not paid at all ("no-pays"), amounts invoiced but not paid in full ("short-pays"), and/or any associated interest charges from prior month(s) invoicing.

A: Interest is charged on any unpaid balance beginning on the original due date, and will continue to accrue until payment is received, or until a bona fide dispute is entered into our system. Each of our pipelines' tariffs provide that interest accrues at an average prime interest rate computed in a manner consistent with Section 154.501(d) of the Commission's Regulations.

A: This site provides access to tariff rates for each rate schedule of each pipeline. This information is available under Tariff then Currently Effective Rates.

For Panhandle, Trunkline and Sea Robin, we provide an additional mechanism by which a rate can be calculated given specific receipt and delivery points, a date and a Rate Schedule. This is available at the top of the Informational Postings screen for each of those pipelines, as well as under Rates then Rate Calculator .

A: If you are a Service Requester on a contract, you can access the Service Requester Contract Location Daily Imbalance Report on Messenger for viewing, emailing or faxing. This report reflects nominations and corresponding allocations on a daily basis at each receipt and delivery location on the contract. This information remains available on-line for 14 months.

See Reports in the Messenger FAQ to learn how to access this information on Messenger.

A: If you are the Operator or a Producer at a location, you can access nominated and allocated volumes on Messenger for viewing, emailing or faxing. A report called Allocation Location Quantity Statement (Daily or Monthly) can be run in the Messenger System. Operators can see all activity at a location; however, to safeguard proprietary information, producers can only see their portion of the data when running the producer report.

See Reports in the Messenger FAQ to learn how to access this information on Messenger.

A: An imbalance occurs when there is a difference between the actual receipt quantity, less the appropriate fuel percentage, and the actual delivered quantity.

A: On Panhandle and Trunkline, daily scheduling penalties occur when a Service Requester's actual delivered quantity varies from the nominated quantity on a gas day, and the variance exceeds the tolerance level. However, there is no daily scheduling penalty charged to any Service Requester at a location if the aggregate deliveries by all Service Requesters at such location do not vary >10% from aggregate nominations.

A: The cash-out process is used to control transport imbalances outside of tolerance levels by selling or purchasing excess delivery or receipt volumes between the pipeline and the Service Requester.

• Excess receipts are purchased by the pipeline.
• Excess deliveries are purchased by the Service Requester.

A: The Messenger system is a proprietary interactive electronic system used by customers of Panhandle Eastern Pipe Line Company, Trunkline Gas Company, Sea Robin Pipeline Company, Lake Charles LNG Company and Southwest Gas Storage Company for transactions associated with nominations, confirmations, allocations, capacity release, contracts, invoicing, which are categorized as Customer Activities, and Informational Postings.

Access this screen by clicking the "Customer Activities" menu option, then "Messenger Information". Once the paperwork has been processed, you will be issued an ID and password. If you have any problems accessing or printing the forms, call the Messenger help line (toll-free at 877-689-7800 or 713-989-7800 in Houston) and a representative will email or fax you the proper forms.

A: Your Messenger password should not have to be reset. If you are having problems getting into Messenger, make sure you are typing in your Messenger ID and password using lowercase letters. If you still cannot get into Messenger, call the Messenger help line (toll-free at 877-689-7800 or at 713-989-7800 in Houston) for assistance.

A: We strongly encourage all users to have their own IDs and are happy to furnish your company as many as you need. Attachment B is the form for adding and deleting Messenger system users. It is available from the Messenger Information screen (see answer to question "How do I become a Messenger User?" above).

If one of your company’s Messenger system users leaves your company, we encourage you to request that we inactivate their ID or assign it to someone else at your company. Use Attachment B for either option.

A: The Messenger System assigns a unique code for every pool or TABS Location. All pool or TABS Service Requesters are encouraged to check their Location imbalances via the Confirmation screen under the Nominations menu. Markets purchasing gas at the pool or TABS Location appear as receipts, with the Service Requestor Name, contract number and volume. Supply into the pool or TABS appears as the delivery volume. If the total at the bottom of the screen is zero, the pool is in balance. A positive total means that the market volume exceeds supply, while a negative total indicates excess supply into the pool. All Service Requesters are encouraged to check the Confirmation screen soon after the nomination deadlines. The Maintain Location Pre-Confirmations tab reflects the pool status for the upcoming cycle.

A: Supply can be ranked on the pooling contract using the Nomination Matrix screen. Ranks should be entered in the Rec Rank field.

A: Poolers are encouraged to rank the markets nominating out of their pools. Rankings can be performed for a future flow date via the Pre-determined Allocation screen under the Flowing Gas option of the Messenger menu.

A: Any reductions will be reflected in the confirmed quantity volumes on the Nomination Matrix screen. In addition, any pool balancing reduction will result in an email with the subject "Service Requestor Pool Balancing Reduction Notification" to both the primary and secondary email address of the Nomination contact on the pooling contract, as well as all other contacts at the company who are set up to receive bump emails. This report lists the nomination that was reduced as well as any AutoPark activity.Pool shippers are also notified when any market contracts are reduced.

A: The AutoPark service balances the pool and keeps the supply and market nominations whole. Pools with excess supply result in a park position, while excess market volumes create an unpark position. The AutoPark service protects a pooler's markets as well as its supply and helps reduce the risk of reductions due to nomination errors.

A: AutoPark transactions are the result of the pool balancing process. A pooler wanting to either park or unpark should leave his pool out of balance. The Messenger System will automatically create a park nomination when supply exceeds market or an unpark nomination when market exceeds supply.

A: A pooler can elect to participate in the AutoPark service by checking the Participate? box next to its AutoPark contract under Flowing Gas >>Auto Pool Balancing>> AutoPark Service Election. Once checked, the election to participate in the AutoPark service is effective until the check is removed. This screen also indicates whether the pipeline is allowing imbalance payback.

A: Once a Service Requestor has been approved for a pool or TABS contract, there are no additional requirements for an AutoPark contract. The Service Requester just has to request and execute a Gas Parking Service (GPS) contract for AutoPark.

A: AutoPark rates can be found on the pipeline's Informational Postings site under Non-critical Notices. There is an in/out charge per dekatherm on the day of the transaction as well a per dekatherm daily charge on the outstanding balance.

A: Imbalance payback is subject to pipeline operating conditions. If payback is being allowed, the pool balancing process will accept up to 1000 dth or a volume equal to the contract imbalance divided by the number of days remaining in the month. A nomination must be entered in the Messenger System for the payback.

A: There are several options. On the Messenger menu, select Flowing Gas>>Imbalance>>View Daily Contract Balance and input your AutoPark GPS contract number to review the GPS balance. In addition, every evening the GPS Ledger Balance Report is emailed to both the primary and secondary email address of the Nomination contact on the GPS contract, and to all other shipper contacts who have elected to receive email bump notifications. The report contains both the daily activity as well as the cumulative balance on the AutoPark contract.

A: For Panhandle, PBAL is the location code for imbalance transactions and AUTOPK is the location code indicating system-generated park/unpark transactions. Both are results of the pool balancing process. On Trunkline, instead of AUTOPK, there is one Location per zone –AUTOWL, AUTONT, AUTO1A and AUTO1B.

A: In order to move gas from one TABS zone to another, a nomination and transportation must occur. Bounce points (i.e. BTW01) are set up in Messenger to be used in this type of nomination. Please contact your sales or optimization representative for rate and contract information if you do not have a current transportation contract. Applicable zone fuel rates apply.
