 Notice Text:


 This Operational Alert is being issued pursuant to Sections 8 and 20, GT&C, of EGT s Tariff to
 notify shippers of unplanned maintenance at EGT s Amber Compressor Station located in Grady
 County, Oklahoma and in EGT s West 1 Pooling Area.
 This unplanned maintenance is scheduled to begin August 22nd, 2023 and is anticipated to be
 completed by 9:00 a.m. on August 26th, 2023.  During this time, Amber will be limited to a
 throughput capacity of 350,000 dth/d.
 Based on current nominations, EGT does not anticipate impacts to its primary firm services.
 However, unforeseen issues, including, but not limited to, nominations, weather conditions,
 storage needs, etc., may result in scheduling reductions.  In the event that unforeseen issues do
 occur, EGT will evaluate nominations, on a case by case basis, based on daily operations to
 alleviate impacts to the extent possible.  During this unplanned maintenance, shippers should
 nominate from their contractual MRO location to reduce risk of scheduling reductions.  Should
 any of the details of this posting change, EGT will notify its shippers and update this notice
 accordingly.
 EGT will schedule nominations, if needed, on each impacted day in accordance with its tariff.
 This alert will remain in effect until further notice.
