This filing is made pursuant to the March 4, 20

II. PROCEDURAL BACKGROUND The following procedural summary provides context for this Third Quarterly Status Report and supplements the procedural histories set forth in Ridgeline's prior quarterly reports. A. Original Filing and Initial Proceedings On May 12, 2022, Ridgeline filed its original application in these dockets, seeking (i) approval of an initial tariff rate for interstate natural gas transportation servic

I. Extensions of Time The procedural history of this matter has been characterized by a series of extensions of time necessitated by the scope of the required tariff redesign: First Extension. Ridgeline filed its first request for extension of time on April 28, 2023, seeking an additional 120 days to complete its response to the Deficiency Letter and to advance the tariff redesign process. ALJ Whitfield granted the f

III. STATUS OF TARIFF REDESIGN A. Overall Progress and Near-Final State Ridgeline is pleased to confirm that the redesign of FERC Gas Tariff, Original Volume No. 1, has reached a near-final state and that Ridgeline fully intends to meet the February 21, 2025 filing deadline established by the ALJ's March 4, 2024 Order.

IV. STATUS OF SETTLEMENT DISCUSSIONS A. Fourth Settlement Conference A fourth settlement conference in these dockets was held on January 18, 2024 before Settlement Judge Howard Margolis. All active parties participated in the conference: (a) Ridgeline Midstream Services LLC, through counsel Calderwood & Harkness LLP (George Trujillo and Brett Callahan); (b) Appalachian Trunk Pipeline Company, LLC, through counsel Kel

1. Return on Equity. The parties remain significantly apart on the appropriate ROE for the Ridgeline Pipeline System. ATPC proposes an ROE of 10.75%, which it contends reflects the lower risk profile of the Ridgeline system in light of its favorable geographic position within the Appalachian production basin. MGPC, supported by the testimony of Dr. Eleanor Vasquez, MGPC's rate expert, proposes an ROE of 11.25%, which

2. Interconnection Cost Allocation. The parties remain unable to agree on the allocation of interconnection facilities costs for the Wetzel County Interconnect. The total estimated cost of the interconnection facilities—including the new meter station, pig launcher/receiver, ultrasonic flow meters, gas chromatographs, SCADA integration, and associated civil and mechanical work—is $22.3 million. ATPC insists on a 50/5

3. Load Factor. All three intervenors—ATPC, MGPC, and CMGA—advocate for a load factor of 85% or higher, contending that the Ridgeline Pipeline System's projected throughput growth justifies a higher load factor assumption than the 75% proposed by Ridgeline. Ridgeline maintains that a 75% load factor is appropriate given the system's current utilization of approximately 56.67% and the uncertainty inherent in throughpu

V. STATUS OF INTERCONNECTION AGREEMENT The Interconnection Agreement between Ridgeline and ATPC for the physical interconnection at the Wetzel County Interconnect is currently in its third draft (Version 3.0, dated April 2023).
