Equitrans L.P. is providing notice of a date change for the upcoming maintenance on its H-109 and H-143 Pipelines. The start date has been updated

In conjunction with this maintenance, all People’s Natural Gas Delivery/Receipt points between Finch Valve Yard (Coordinates 39.92356

ET on September 29, 2026, and remain shut in for the duration of this maintenance.

supplier, operator, or transporter fails to comply with the terms of an OFO, such Customer shall (a) be liable for any damages including, but not

subject to a penalty of three (3) times the Midpoint price reported for Texas Eastern, M-2 receipts or Eastern Gas, South. whichever is greater, as

control and capabilities.

Estimated duration of outage is 26 hours. Upon completion of the maintenance the OFO will expire and Equitrans L.P. will notify impacted parties
when they can turn back in-line.
