Systemwide Notes:
(1) AGT has scheduled Transco Centerville receipts to the design meter capacity of 222,526 Dth/d.
(2) Due to the planned outage, AGT has restricted 100% of No Notice delivering to the J system.
AGT requests that customers/point operators on AGT be aware of the impact non-ratable hourly takes from the system may have in causing delivery pressures reaching lower than desired levels.
AGT's system is not designed to sustain delivery pressures above contract levels while making non-ratable/accelerated deliveries above scheduled quantities for more than 6 consecutive hours, to be followed by flows below scheduled quantity for the balance of any 24-hour period. If customers/point operators don't manage hourly takes from the system, 1) delivery pressures will be impacted and /or 2) AGT may be required to impose further restrictions or courses of action in order to maintain the operational integrity of the system.
AGT may be required to issue system specific, meter specific and/or hourly OFO's pursuant to General Terms and Conditions Section 26.7(d) to impose further restrictions in order to maintain the operational integrity of the system.
Customers are advised that capacity may become available as the nomination and confirmation process continues throughout the day.
Please contact your Operations Account Representative should you have any questions.
