Equitrans L.P. is providing notice of a date change for maintenance scheduled on its TP-371 Pipeline. The TP-371 Pipeline Pigging that was

Equitrans L.P. will be conducting pipeline pig runs on its TP-371 Pipeline in AVC Operational Area 2 beginning at 8:00 AM ET on August 13,
2024, and is issuing an OFO in accordance with Section 6.11 of the General Terms and Conditions of its FERC Gas Tariff.

Equitrans L.P is hereby providing notice that due to the high possibility of fluids during this pig run all People’s Natural Gas Delivery/Receipt
Meters between Valley Station (Coordinates 40.791516 / -79.364074) and Derry Interconnect (Coordinates 40.33057 / - 79.22438)) on the TP-
371 Pipeline must be shut in by 8:00 AM ET on August 13, 2024, and remain shut in for the duration of the pigging.

Additionally, in conjunction with this pigging, the following Customer Receipt Meters: #M5210199 (Beagle), #17048 (Reveese Salem
Interconnect), #5210790 (Duff), #5203871 (Ecker), and #5203873 (Frye Lateral at Ecker) must be shut in by 8:00 AM ET on August 13, 2024,
and remain shut in for the during of the pigging. Nominations should be adjusted accordingly.

If Customer and/or Customer’s operator fails to comply with the terms of this OFO, such Customer shall be subject to (1) liability for any
damages including, but not limited to, direct, consequential, exemplary, or punitive damages incurred by Equitrans or any other party as a result
of such failure, (2) a penalty of $25 per Dth times the quantity of gas by which the Customer deviated from the requirements of this OFO, (3) flow
control, and/or (4) a reduction in scheduled quantities to match flowing gas. In addition, Equitrans will not permit post-cycle adjustments to avoid
an OFO penalty.

Estimated duration of the pigging is 50 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.

Customers should monitor Equitrans’ Informational Postings website for updates to this notice.
