Overview STBA, SC-16, MMNGS, and SATS Suppliers are respnsible fr delivering gas supply t Distributin s City Gate in amunts calculated by Distributin as described in the New Yrk and Pennsylvania GTOP manuals. Fr each custmer, a Daily Delivery Quantity ("DDQ") is determined and cmbined with ther custmers DDQs t prduce the Aggregated Daily Delivery Quantity ("ADDQ"). Fr amunts delivered t the City Gate by the Supplier utside f applicable ADDQ tlerances, the Supplier will incur charges as described in the New Yrk and Pennsylvania Tariffs and GTOP manuals. Daily city gate imbalances are finalized during mnthly prcessing, which ccurs apprximately nine business days fllwing the end f the mnth. The actual mnthly prcessing schedule is detailed n the TSS Calendar psted n the NFGDC TSS Supprt Site: 4. END OF MONTH BURNER TIP IMBALANCE RECONCILIATION A.

Nte that fr each Aggregatr all individual PA MMNGS and PA SATS market pls are autmatically cmbined int the zer pl and trading is cnducted n this zer pl (PABCS00). New Yrk STBA, DMT, and SC-16 Aggregatrs can trade with each ther. Nte that fr each Aggregatr all individual NY STBA and NY DMT market pls are autmatically cmbined int the zer pl and trading is cnducted n this zer pl (NABCS00). TSS allws tw trading sessins per day fr 3 cnsecutive business days immediately fllwing the cmpletin f prcessing each mnth. The first day f trading sessins each mnth will typically be n r abut the 10th business day fllwing the end f the mnth being prcessed.

CASH-OUT Under the Cash-ut Optin, Distributin either purchases a surplus imbalance frm the Aggregatr r sells a vlume t the Aggregatr sufficient t ffset a deficiency imbalance. The Aggregatr may elect thrugh TSS t cash-ut all r part f their imbalance psitin fr NY SC-16. Any remaining SC-16 imbalance will be handled cnsistent with the Imbalance Rllver ptin. Any remaining NY STBA, NY DMT, PA MMNGS, and PA SATS imbalance will be autmatically cashed ut at the zer pl level each mnth. Reference the NY and PA GTOP manuals fr specific infrmatin n the varius rate tiers applicable t cash-ut vlumes and fr the varius safe-harbr mechanisms that enable marketers t be cashed ut at the market pricing tier. NY SC-16 aggregatrs have the pprtunity t elect that Distributin cash ut imbalances at the end f the trading perid. This cash-ut electin des nt carry frward frm mnth t mnth. The Aggregatr must select the cash-ut chice within TSS each mnth it elects mnth-end imbalance psitins t be cashed-ut. Distributin may elect nt t satisfy cash-ut purchase requests r cash-ut sales requests during a mnth. Distributin s electin will be cmmunicated thrugh the EGISL screen in TSS prir t the initiatin f trading. Distributin will autmatically cash-ut any remaining pst-trading NY DMT, NY STBA, PA MMNGS, and PA SATS surplus r deficiency imbalances at the zer pl level nted abve. Distributin will autmatically cash-ut any remaining pst-trading NY SC-16 deficiency imbalances. 10

11 The prcedure t elect a cash-ut fr NY SC-16 is as fllws: At the cnclusin f the trading perid, a final imbalance psitin will be calculated fr each Aggregatr and will be made available via EGISL in TSS. By the business day fllwing cnclusin f the trading perid, as detailed n the mnthly TSS calendar, an SC-16 aggregatr must ppulate a check ff bx and specify a vlume via TSS t request the cash-ut by selecting: Custmer Activities Flwing Gas Imbalance Imbalance Trading Imbalance Cashut Vlume r enter shrtcut EICOV and Run Shuld Distributin schedule a cash-ut, a revised final imbalance psitin will be calculated fr each affected Aggregatr and will be psted via EGISL in TSS. 7. ROLLOVER Any final remaining SC-16 surplus imbalance will be redelivered in the next fllwing mnth, as perating cnditins permit. In practice, this has meant that January imbalances, fr example, are redelivered t February. Rllver f deficiency imbalances fr SC-16 is nt allwed. Any final remaining SC-16 deficiency imbalance will autmatically be cashed ut. NY STBA, NY DMT, PA MMNGS, and PA SATS final remaining deficiency r surplus imbalances will autmatically be cashed ut. 8. OPTIONAL ROLLOVER METHODOLOGY FOR MMNGS (available nly when mandatry cash-ut has been turned ff in PA) Under this methdlgy, an MMNGS deficiency r surplus may be applied t the remaining days f the mnth after the imbalance ccurs, as perating cnditins permit, as an additin t, r deductin frm, the ADDQs calculated fr that mnth. In practice, this means all, r part, f a January imbalance, fr example, may be applied as an additin t, r deductin frm, the ADDQ calculated fr the remaining days f February after trading and cashuts have been cmpleted. Any remaining imbalance vlume will be prcessed accrding t the default rllver methdlgy as described 11
