LETTER OF NOTIFICATION FOR THE AZALEA 138KV EXTENSION EAST PROJECT PUCO Case No. 14-0195-EL-BLN Submitted pursuant to OAC 4906-11-01 AEP Ohio Transmission Company (AEP Ohio Transco) February 2014 LETTER OF NOTIFICATION Azalea 138kV Extension East Project – New 138kV Service to Utica East Ohio Midstream, LLC (Momentum) in Leesville, Ohio The following information is being provided in accordance with the procedures delineated in Ohio Administrative Code Section 4906-11-01: Letter of Notification Requirements of the Rules and Regulations of the Ohio Power Siting Board. 4906-11-01 (B): General Information 4906-11-01 (B) (1) a: Name and Reference Number Name of Project: The name of the project is the Azalea 138kV Extension East. 2014 LTFR Reference: The proposed Project will be identified in the 2014 LTFR. The reference number will be supplied at a later date. 4906-11-01 (B) (1) b: Brief Description of Project American Electric Power Ohio Transmission Company (AEP OH Transco) is proposing to construct a 1.35-mile overhead 138 kilovolt (kV) electric transmission line to serve a natural gas processing facility to be owned and operated by Utica East Ohio Midstream, LLC (Momentum) south of Leesville, in Orange Township, Carroll County, Ohio. Exhibit 1 shows the general location of the Project. Exhibit 1 is a partial copy of the United States Geological Survey, Carroll County, Ohio Quad, Map ID 40081-D2. Exhibit 2 provides an aerial photograph of the Project area showing the proposed route and existing lines. AEP OH Transco proposes to build a hard tap off of AEP’s existing Leesville Station, and build approximately 1.35 miles of 138kV electric transmission line to the Momentum 69kV station location, in order to provide service to Momentum’s Leesville UEO Station. AEP OH Transco has worked with Momentum to develop a route that uses Momentum’s acquired right-of-way (ROW) from their facility to the existing AEP’s existing Leesville Letter of Notification 1 Azalea 138kV Extension East Station. Although the line will initially be operated at 69kV, the Project will be designed and built to 138kV specifications to account for future area improvements and source injection into the area due to the shale gas activity. Twenty new, galvanized steel pole structures will be installed. Thirteen of these are tangent poles, four are running angles, two are dead ends, and one is hard tap. The proposed structures will be approximately 70 to 100 feet tall. The Project will require a 100-foot wide permanent ROW, and a portion of the project is adjacent to an existing distribution line ROW. 4906-11-01 (B) (1) c: Why the Project Meets the Requirements for a Letter of Notification The Project falls under Item (1) (f) of the Interim Application Requirement Matrix for Electric Power Transmission Lines, in Appendix A of 4906-1-01. This section of the Code states that an applicant may use the Letter of Notification (LON) process if the Project is: (1) An electric transmission line that is: (f) Line(s) primarily needed to attract or meet the requirements of a specific customer or customers. The Project presented in this LON fulfills this condition. The Project will meet the need requirements of Momentum for the Leesville UEO Station. 4906-11-01 (B) (2): Need for the Project The Project will serve the load for Momentum’s new Leesville UEO Station, which is expected to be approximately 20 mega volt amperes (MVA) by July 1, 2014, 45 MVA by January 1, 2015, and 62 MVA by June 1, 2015. 4906-11-01 (B) (3): Location Relative to Existing or Proposed Lines The Bowerston-Leesville 69 kV transmission line is the only existing transmission line in the Project area. This line does not intersect with the proposed transmission line, but is located in the eastern portion of the Project Area at the existing Leesville substation. The Letter of Notification 2 Azalea 138kV Extension East AEP Ohio Transco Bowerston-Leesville 69 kV transmission line exits the south side of the Leesville substation and heads south towards the village of Bowerston. 4906-11-01 (B) (4): Alternatives Considered Due to the location of the existing substation and the Momentum facility, no significant alternatives were studied as part of this project. Small-scale alternatives within the proposed ROW were considered in order to reduce environmental impact and to meet engineering needs. 4906-11-01 (B) (5): Construction Schedule Construction on the proposed Project is scheduled to begin on or about May 1, 2014, with a proposed in-service date of July 1, 2014. Tree clearing is scheduled to begin in March 2014 to avoid impacts to the Indiana bat. 4906-11-01 (B) (6): Area Map Exhibit 1 is a map depicting the general location of the Project site. To locate and view the Project site from the Columbus, Ohio area: • Take I-70 East toward Wheeling for approximately 80 miles. • Merge onto I-77 North via Exit 180B toward Cleveland. • After approximately 21 miles, take Exit 65 for US-36 toward Newcomerstown/Port Washington. • Turn right onto US-36 East. • After approximately 14 miles, US-36 East becomes US-250 East/OH-800 South. • After 1.4 miles, turn left onto US-250. • After 4.5 miles, turn left onto Patterson Road/OH-151. • Stay on OH-151 for 5 miles and then turn left onto Leesville Road/OH-212. • The Project begins approximately 1.6 miles north on the right. Letter of Notification 3 Azalea 138kV Extension East AEP Ohio Transco 4906-11-01 (B) (7): Property Owner List This project will be located on new transmission line easements that have been obtained by AEP. AEP ROW agents worked with the property owners on which Momentum had already acquired ROW for a proposed gas pipeline. The gas pipeline is no longer proposed in the area. 4906-11-01 (C): Technical Features of the Project 4906-11-01 (C) (1): Operating Characteristics AEP will design and construct the new transmission line for 138kV operations; however, initially it will only be energized to 69kV. Additional details are included in Section 4906-11-02 (B) (2) above. The transmission line has the following characteristics: Voltage: 138 kV Alternating Braced Post Conductor: (3) 959,600 CM, Type 16: Suwannee-ACSS/TW Shield Wire: (1) 7#8 Alumoweld Structure types Structure 1: Direct Embedded with guying where required 4906-11-01 (C) (2) (a): Calculated Electric and Magnetic Fields EMF levels were computed one meter above ground under the line and at the ROW edges (50/50 feet, left/right, from centerline). Our results, calculated by Carlos Casablanca using EPRI's EMF Workstation "Enviro" computer program, are summarized below.

Loading Emergency Loading Winter Normal (A) (A) Loading (A) Azalea – Dennison – 184 258 2368 Desert Road Circuit 4906-11-01 (C) (2) (b): EMF Discussion Three loading conditions were examined: (1) normal maximum loading, (2) emergency loading, and (3) winter normal conductor rating, consistent with the OPSB requirements. Normal maximum loading represents the peak flow expected with all facilities in service; daily/hourly flows can fluctuate below this level. Emergency loading is the maximum current flow during unusual (contingency) conditions, which exist only for short periods of time. Winter normal (WN) conductor rating represents the maximum current flow that a line, including its terminal equipment, can carry during winter conditions. It is not anticipated that the Azalea Extension would operate at its WN rating in the foreseeable future. 4906-11-01 (C) (3): Estimated Costs The 2014 capital cost estimates for the proposed project have been tabulated by the Federal Energy Regulatory Commission (FERC) Electric Plant Transmission Accounts: Letter of Notification 5 Azalea 138kV Extension East AEP Ohio Transco ESTIMATES OF APPLICABLE INTANGIBLE AND CAPITAL COSTS FERC Account Description Cost Number 350 Land and Land Rights $499,129 352 Structures & Improvement Not Applicable 353 Substation Equipment Not Applicable 354 Towers & Fixtures Not Applicable 355 Poles & Fixtures $955,536 356 Overhead Conductors & Devices $987,622 357 Underground Conductors & Devices Not Applicable 358 Underground-to-overhead Conversion Equipment Not Applicable 359 Right-of-way Clearing, Roads, Trails or Other Not Applicable Access TOTAL $2,442,287 4906-11-01 (D): Socioeconomic Data 4906-11-01 (D) (1): Land Use Land along the proposed ROW consists of agricultural land (1,231 linear feet), existing access road (17 linear feet), existing ROW (1,428 linear feet), paved road (46 linear feet), unpaved road (13 linear feet), forests (2,043 linear feet), industrial (514 linear feet), open land (551 linear feet), residential (170 linear feet), palustrine emergent (PEM) wetland (305 linear feet), and palustrine scrub-shrub (PSS) wetland (843 linear feet).
