III. VERIFICATION OF KEY DATA — SYSTEM DESCRIPTION

8. I hereby verify, to the best of my knowledge, information, and belief, the accuracy of the following system data as presented in the Application and the accompanying Exhibits:

9. Pipeline System. The Ridgeline Pipeline System (the "System") is a newly constructed, 187-mile, 24-inch-diameter high-pressure natural gas transmission pipeline. The System was designed and constructed to transport natural gas produced in the Appalachian Basin, principally from Marcellus and Utica shale formations, from points of receipt in northern West Virginia to points of delivery in southwestern Pennsylvania.

10. Receipt Point. The primary receipt point on the Ridgeline Pipeline System is the Wetzel County Interconnect, located in Wetzel County, West Virginia, at approximate geographic coordinates 39.6120° N latitude, 80.7540° W longitude. This receipt point serves as the origin of the System at milepost 0.0.

11. Delivery Point. The primary delivery point on the Ridgeline Pipeline System is the Waynesburg Compressor Station, located in Greene County, Pennsylvania, at approximate geographic coordinates 39.8965° N latitude, 80.1810° W longitude.

12. Design Capacity. The Ridgeline Pipeline System has a design capacity of 1.2 billion cubic feet per day ("Bcf/d"), equivalent to 1,200,000 dekatherms per day ("Dth/d") at an assumed BTU content of 1,000 BTU per standard cubic foot. This design capacity reflects the maximum sustainable throughput of the System under normal operating conditions and with all compressor stations operating at full capacity.

13. Current Throughput. As of the test year, the System's current throughput is approximately 680 million cubic feet per day ("MMcf/d"), which represents approximately 56.67% utilization of design capacity. The Company anticipates that throughput will increase over time as additional firm transportation service agreements are executed and as market conditions support increased production in the Appalachian Basin.

14. Compressor Stations. The Ridgeline Pipeline System is served by three compressor stations: (i) Wetzel Station, located near the receipt point in Wetzel County, West Virginia; (ii) Mannington Station, located at an intermediate point along the pipeline route in Marion County, West Virginia; and (iii) Waynesburg Station, located at the delivery point in Greene County, Pennsylvania. The aggregate installed compressi

15. In-Service Date. The Ridgeline Pipeline System was placed in service on October 1, 2021, following completion of construction and successful hydrostatic testing, commissioning, and receipt of all necessary federal, state, and local permits.

16. Original Construction Cost. The original construction cost of the Ridgeline Pipeline System, including pipeline facilities, compressor stations, meter stations, rights-of-way, and associated infrastructure, totals $587.2 million. This figure is consistent with the final project cost report prepared by the Company and has been reflected in the Company's books of account.

IV. VERIFICATION OF KEY DATA — RATE BASE AND COST OF SERVICE

17. I hereby verify, to the best of my knowledge, information, and belief, the accuracy of the following financial data as presented in the Application and Exhibit Nos. A through P. A. Rate Base

18. The rate base for the Ridgeline Pipeline System, as filed and calculated for the test year ended March 31, 2022, consists of the following components: (a) Net Plant in Service: $563.71 million. This figure represents the original construction cost of $587.2 million, less accumulated depreciation of $23.49 million. Accumulated depreciation was calculated on a straight-line basis at a composite depreciation rate of

19. The test-year cost of service for the Ridgeline Pipeline System, as presented in the Application, totals $97.36 million and consists of the following components: (a) Return on Rate Base: $61.62 million. This amount represents the product of the total rate base of $612.40 million and the weighted average cost of capital of 10.0625%, as described in paragraph 22 below. (b) Depreciation Expense: $14.68 million. Depr

20. Capital Structure. The proposed capital structure for Ridgeline Midstream Services LLC, as presented in the Application, consists of 55% equity and 45% debt. This capital structure reflects the actual capitalization of the Company and is consistent with the capital structures of comparable natural gas pipeline companies.

21. Cost of Capital Components. The proposed return on equity is 14.00%, based on a discounted cash flow ("DCF") proxy group analysis performed in accordance with Commission precedent, as set forth in Exhibit I to the Application. The cost of debt is 5.25%, representing the weighted average interest rate across two debt tranches, as described in Section VII of this Verification.

22. Weighted Average Cost of Capital. The resulting weighted average cost of capital is 10.0625%, calculated as follows: (55% × 14.00%) + (45% × 5.25%) = 7.70% + 2.3625% = 10.0625%.

V. VERIFICATION OF KEY DATA — RATE DESIGN

23. I hereby verify, to the best of my knowledge, information, and belief, the accuracy of the proposed rate design for the Ridgeline Pipeline System as presented in the Application and the proposed tariff sheets filed as part of the FERC Gas Tariff, Original Volume No. 1.

24. Billing Determinants. The billing determinants used in the rate design are 438,000,000 Dth per year, derived from the design capacity of 1,200,000 Dth/d multiplied by 365 days per year, assuming a 100% load factor. This calculation is consistent with Commission policy for establishing initial rates based on full design capacity of a new pipeline.

25. Proposed Initial Recourse Rate. The proposed initial recourse rate for firm transportation service under Rate Schedule FT-1 is $0.2265 per Dth (total), consisting of a reservation component of $0.2223 per Dth and a usage component of $0.0042 per Dth. The reservation component reflects the fixed costs of the System that are recovered through monthly reservation charges, while the usage component reflects the varia

26. Rate Derivation. The proposed total rate was derived by dividing the total annual cost of service of $97.36 million by the annual billing determinants of 438,000,000 Dth per year, yielding a rate of $0.2223 per Dth for the reservation component (rounded). The usage component of $0.0042 per Dth was calculated separately based on the variable cost allocation, with the reservation/usage split between these component

27. Tariff Type. The proposed tariff is filed as a Part 284, Subpart G open-access transportation tariff in compliance with the Commission's regulations and policies governing open-access natural gas pipeline transportation services. The proposed rates, terms, and conditions are designed to be applied on a non-discriminatory basis to all shippers seeking service on the Ridgeline Pipeline System.
