LETTER OF NOTIFICATION BRUCE MANSFIELD – GLENWILLOW 345 kV TRANSMISSION LINE PROJECT OPSB Case No. 12-1726-EL-BLN 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 (―OPSB‖). 4906-11-01(B): General Information 4906-11-01(B)(1)a: Name and Reference Number Name of Project: Bruce Mansfield – Glenwillow 345 kV Transmission Line Project (―Project‖) 2012 LTFR Reference: This Project is not identified in FirstEnergy Corp.’s 2012 Electric Long-Term Forecast Report (―LTFR‖) submitted to the Public Utility Commission of Ohio in Case Number 12-0504- EL-FOR. 4906-11-01(B)(1)b: Brief Description of Project American Transmission Systems, Incorporated (―ATSI‖ or the ―Applicant‖), a wholly owned subsidiary of FirstEnergy Corp., is seeking a Certificate of Environmental Compatibility and Public Need to construct the Bruce Mansfield – Glenwillow 345 kV Transmission Line (the ―Project‖). Included in this Letter of Notification (―LON‖) application as part of the Project is the construction of the short looped extensions of the existing Eastlake – Juniper and Inland – Perry 345 kV Transmission Line to the Glenwillow Transmission Switching Substation. The overall project consists of constructing a new 345 kV transmission line approximately 114.5 miles in length between the existing Bruce Mansfield Substation in Beaver County, Pennsylvania and the proposed new Glenwillow Transmission Switching Substation to be located in the Village of Glenwillow in Cuyahoga County, Ohio. This LON application concerns both the portion of the proposed Project to be constructed within Ohio, which is approximately 103.6 miles in length, and the approximately 390-foot and 315-foot long looped extensions of two existing 345 kV transmission lines into the new Glenwillow American Transmission Systems, Incorporated 1 Bruce Mansfield – Glenwillow 345 kV Transmission Line Project A FirstEnergy Company November 2012 Substation. Concurrent with this LON application, ATSI has submitted an application to the Board seeking a Certificate of Environmental Compatibility and Public Need for the proposed Glenwillow Switching Station Project in Board Case Number 12-1727-EL- BSB. A Preferred and an Alternate Site for the Glenwillow Transmission Switching Substation (―Glenwillow Substation‖) are proposed in this Application. The Project’s transmission line construction proposed in this LON connects to the proposed Preferred Site of the Glenwillow Substation. As proposed and described in this LON application, the Bruce Mansfield – Glenwillow 345 kV Transmission Line portion of the Project begins at the Ohio-Pennsylvania border in Middleton Township, Columbiana County, Ohio, traverses in a northwesterly direction through Columbiana, Mahoning, Trumbull, Portage, Summit, and Cuyahoga counties, and terminates at the proposed Glenwillow Switching Station proposed to be located in the Village of Glenwillow in Cuyahoga County. The route utilizes a combination of available ―open arm‖ positions on existing 345 kV lines, re-energizing an existing but inactive 345 kV circuit and rebuilding existing single circuit 345 kV lines for double circuit operation. ―Open arm‖ refers to a transmission structure that was designed and built to carry two circuits, but for which only one circuit was installed. The sections of single circuit line to be reconstructed total approximately 29.2 miles and will require replacing approximately 205 existing structures. Approximately 25 new structures will be installed along the route of the new construction, generally at locations where the route crosses existing transmission lines or at transitions from the proposed open arm sections to the rebuild sections of construction. Descriptions of the general locations and arrangements of the new structures are included in the Project route description provided below. Additionally, in the 53-mile section between the Bruce Mansfield Substation and Highland Junction, the conductors of that circuit will be used as part of the new Bruce Mansfield – Glenwillow 345 kV Transmission Line, and the new construction will be used for the existing circuit. For clarity purposes, the various route segments are referred to by ―Link‖ Numbers 1 through 5 and 7 through 14, as presented in Table 1.

The Pennsylvania portion of the proposed transmission line begins at the Bruce Mansfield Substation in Shippingport Borough, Beaver County, Pennsylvania. Three new structures will be installed adjacent to the Bruce Mansfield Substation to support the transmission line. The route then traverses approximately 11 miles on the open arm of the existing Mansfield – Highland 345 kV Transmission Line structures through Shippingport, Industry, and Ohioville boroughs and South Beaver Township before reaching the Ohio border (Link 1). The route of the Ohio portion of the transmission line proposed in this LON application continues from the Ohio border on the open arm of the existing Mansfield – Highland 345 kV Transmission Line structures in a northwesterly direction for approximately 31.5 miles through Middleton, Unity, and Fairfield townships in Columbiana County and Beaver, Green, Canfield, and Ellsworth townships in Mahoning County to a point west of Canfield, approximately 500 feet north of the intersection of Gault Road (Route 73) and North Palmyra Road (Link 2). The existing right-of-way (―ROW‖) through this section of the route is generally 180 feet wide so no new ROW is required.
