I. INTRODUCTION AND QUALIFICATIONS Q. Please state your full name, title, and business address. A. My name is Thomas Greaves. I am the Vice President of Engineering and Operations of Ridgeline Midstream Services LLC. My business address is 700 Kanawha Boulevard East, Suite 1400, Charleston, West Virginia 25301. Q. On whose behalf are you submitting this testimony? A. I am submitting this pre-filed direct testimony on

II. OVERVIEW OF THE RIDGELINE PIPELINE SYSTEM Q. Please provide a general overview of the Ridgeline Pipeline System. A. The Ridgeline Pipeline System is a high-pressure interstate natural gas transportation pipeline located in the Appalachian Basin, traversing portions of Wetzel County, West Virginia, and Greene County, Pennsylvania, as well as intermediate counties in West Virginia. The system was designed, engineer

III. COMPRESSOR STATIONS Q. Please describe the compressor stations on the Ridgeline Pipeline System. A. The Ridgeline Pipeline System includes three compressor stations with an aggregate installed compression of 45,000 horsepower ("HP"). Each station was designed and constructed under my supervision and was placed in service concurrently with the pipeline on October 1, 2021. The three stations are strategically loca

1. Wetzel Station. The Wetzel Station is located near the receipt point at the Wetzel County Interconnect in Wetzel County, West Virginia, at approximately Milepost 2.5 of the Ridgeline Pipeline System. This station provides initial compression for gas entering the system, boosting receipt-point pressure to the operating pressure required for efficient long-distance transmission through the 24-inch pipeline. The Wetz

2. Mannington Station. The Mannington Station is located at an intermediate point along the pipeline route, approximately at the midpoint of the 187-mile system, at approximately Milepost 94.0, in Marion County, West Virginia. The Mannington Station provides mainline boost compression to maintain operating pressure and flow rates across the Appalachian terrain, compensating for friction losses and elevation changes e

3. Waynesburg Station. The Waynesburg Station is located at the delivery point of the Ridgeline Pipeline System in Greene County, Pennsylvania, at Milepost 187.0. The Waynesburg Station serves as the terminal compressor station, providing final compression for delivery of gas into downstream pipeline interconnections at the required delivery pressures specified in the applicable transportation agreements. The Waynesb

IV. CURRENT THROUGHPUT AND UTILIZATION Q. What is the current throughput on the Ridgeline Pipeline System? A. As of the test year ended March 31, 2022, the Ridgeline Pipeline System's current throughput is approximately 680 million cubic feet per day ("MMcf/d"), which is equivalent to approximately 680,000 Dth/d at the assumed average heating value of 1,000 BTU per standard cubic foot. This throughput level represent

V. PIPELINE CONSTRUCTION AND ENGINEERING SPECIFICATIONS Q. Please describe the construction of the Ridgeline Pipeline System. A. The construction of the Ridgeline Pipeline System was a major infrastructure project that I directed from the initial engineering phase through the in-service date. Construction commenced in early 2020, following the completion of all necessary permitting and regulatory approvals, and was c

VI. PROPOSED INTERCONNECTION FACILITIES AT THE WETZEL COUNTY INTERCONNECT Q. Please describe the proposed interconnection with ATPC. A. Ridgeline seeks authorization under Docket No. RP22-847-001 for the construction and operation of physical interconnection facilities to enable the interconnection of the Ridgeline Pipeline System with the existing pipeline network of Appalachian Trunk Pipeline Company, LLC ("ATPC")

1. Meter Station. The centerpiece of the proposed interconnection facilities is a new measurement facility consisting of three ultrasonic flow meter runs, each 12 inches in diameter, with associated flow conditioning equipment. The three meter runs are arranged in a parallel configuration, with headers and isolation valves enabling any combination of one, two, or three runs to be placed in service at any time. Each m

2. Gas Chromatographs. The meter station includes two on-line gas chromatographs for continuous gas quality analysis. The gas chromatographs are dual-redundant, with one serving as the primary analyzer and the second as a backup. The chromatographs continuously measure the compositional analysis of the gas stream, including the mole percentages of methane, ethane, propane, butanes, pentanes and heavier hydrocarbons,

3. SCADA Integration. The meter station instrumentation is fully integrated with both Ridgeline's and ATPC's SCADA systems for real-time data exchange, flow measurement recording, and operational coordination. The SCADA integration design provides for the continuous transmission of flow rate, pressure, temperature, gas quality, and alarm data from the meter station to both Ridgeline's operations center in Charleston,

4. Pig Launcher/Receiver Facility. The proposed interconnection facilities include a new pig launcher at the Wetzel County Interconnect, located at Milepost 0.0 of the Ridgeline Pipeline System, and an associated pig receiver. The pig launcher is a 24-inch-diameter barrel-type launcher with a quick-opening closure rated for the pipeline MAOP of 1,440 psig. The launcher and receiver are designed to accommodate ILI too

5. Valving and Piping. The interconnection facilities include mainline isolation valves, pressure regulation equipment, check valves for backflow prevention, and interconnecting piping between ATPC's 30-inch mainline and Ridgeline's 24-inch header. The mainline isolation valves are 24-inch full-opening ball valves with pneumatic actuators for remote operation via the SCADA system. Pressure regulation equipment includ

6. Site Infrastructure. The interconnection facility site includes a control building housing the meter station electronics, gas chromatographs, SCADA equipment, telecommunications equipment, and battery backup systems. The control building is a prefabricated, climate-controlled structure with fire detection and suppression systems. Electrical power is supplied by a dedicated service from the local utility, with an o

VII. RESPONSE TO ATPC'S PROTEST REGARDING METERING STATION DESIGN Q. Are you familiar with the protest filed by ATPC on August 15, 2022? A. Yes. On August 15, 2022, ATPC, through its counsel at Kellner, Royce & Dillard LLP (lead counsel William Pratt), filed a protest and motion to intervene in Docket No. RP22-847-001. Among other things, ATPC's protest challenges the adequacy of Ridgeline's proposed receipt-point me
