MCCRORY GOVERNOR March 18, 2013 Mr. John Thomas U.S. Army Corps of Engineers Raleigh Regulatory Field Office 3331 Heritage Trade Drive, Suite 105 Wake Forest, NC 27587 ANTHONY J. TATA SECRET. -kRY RE: Updated Stream Impacts for the Application for Section 404 Individual Permit and Section 401 Water Quality Certifications for the Bowers to Lake Rail Improvements Project, Davidson County. TIP C- 4901A,D Dear John, As you know, the North Carolina Department of Transportation (NCDOT) Rail Division (Rail Division) has proposed railroad improvements to approximately 4.2 miles of rail within the North Carolina Railroad Company (NCRR) /Norfolk Southern Corporation (NS) railroad corridor extending from station "Bowers" to a point approximately 250 feet south of station "Lake" in Davidson County. The project area associated with the C -4901 project encompasses approximately 183.3 acres and generally consists of the area within 100 feet of the center of the existing railway and outward along Upper Lake Road (State Route [SR] 2024) and Turner Road (SR 2005). Along these roadways, the project area extends up to 1475 feet from the existing rail line with widths that range from 75 to 350 feet from the roadway center. An application for authorization to impact areas subject to Section 404 jurisdiction was submitted in January 2013, and was placed on Public Notice from January 29 to February 28, 2013. Subsequent to permit submittal, the Rail Division was requested by the NCDWQ to revise stream impact calculations using more accurate stream locations. The locations of streams determined to be jurisdictional were refined using a combination of detailed topographic mapping and field surveys. MAILING ADDRESS: NC DEPARTMENT OF TRANSPORTATION RAIL DIVISION 1553 MSC RALEIGH NC 27699 -1553 TELEPHONE: 919-707-4700 FAX: 919 - 715 -6580 WEBSITE: WWW.BYTRAIN.ORG LOCATION: TRANSPORTATION BUILDING 1 SOUTH WILMINGTON STREET RALEIGH NC Please note that all changes to impacts are due to the refinement of stream length calculations based on surveyed /modeled streams, with the exception of changes to impacts at Site 12 (please see the attached permit drawings, Sheet 12). Site 12 has the most significant increase due to a slight revision of design plans as requested by the NC Railroad Company to remove the existing culvert under the rail and direct drainage to the existing stream via ditch to avoid future maintenance issues; however, the proposed revision falls entirely within the existing project footprint. At this site, design revisions result in approximately 17 feet of additional impact, and the recalculation of stream lengths results in approximately 46 additional feet of impact. The following table summarizes changes to stream impacts. Table 1.

The recalculation of stream lengths accounts for approximately 74 feet of additional permanent impacts, and the design revision at Site 12 accounts for the remaining 17 feet of additional permanent impacts. Some slight changes to temporary impacts at individual sites were calculated; however, total temporary stream impacts due to this project have not changed. Please find attached to this letter a set of revised Permit Drawings and the associated Wetland Permit Summary Sheet.
