TROGDON, III SECRETARY Subject: Application for Section 404 Nationwide Permits 13, 23 & 33 and 401 Water Quality Certification for the Proposed Replacement of Bridge 139 on SR ll 39 over East Branch Toxaway Creek in Transylvania County, Federal Aid Project No. BRZ-1127(12); TIP B- 5405, Division 14; Work Order WBS Element 46120.1.1. Dear Madam: The North Carolina Department of Transportation (NCDOT) proposes to replace bridge number 139 on SR 1139 (Old Toxaway Road) over Toxaway Creek in Transylvania County with a single span, 60 feet long cored slab bridge to the south of the existing alignment. The existing bridge will be utilized as an onsite detour during construction. This action will result in 601f feet of permanent impacts resulting from bank stabilization (341 fl and energy dissipaters/roadway fill (26 1�. There will be < 0.01 acres (48 1 fl of temporary impacts to surface waters from bank stabilization installation and temporary dewatering. Mitigation has been acquired from NCDMS for the 261f of roadway iill. Please see enclosed copies of the Pre-Construction Notification (PCN), NCDMS Acceptance Letter, Stormwater Management Plan, Permit Drawings, and Roadway Plansheets. A Categorical Exclusion (CE) was completed in October 2015 and distributed shortly thereafter. Additional copies are available upon request. This project is located in a trout watershed; therefore comments from the NCWRC will be required prior to authorization by the Corps of Engineers. By copy of this letter and attachment, NCDOT hereby requests NCWRC Review. NCDOT requests that NCWRC forward their comments to the Corps of Engineers and the NCDOT within 30 calendar days of receipt of this application. This project calls for a letting date of February 20, 2018 and a review date of January 2, 2018.

Based on the information supplied by you on June 16, 2017, the impacts are located in CU 03o60101 of the Savannah River basin in the Southern Mountains (SM) Eco-Region, and are as follows: Savannah Stream Wetlands Buffer (Sq.

See permit application for details. The impacts and associated mitigation needs were under projected by the NCDOT in the 2017 impact data. DMS will commit to implement sufficient cornpensatory stream mitigation credits to offset the impacts associated with this project as determined by the regulatory agencies using the delivery timeline listed in Section F.3.c.iii of the In-Lieu Fee Instrument dated July 28, 2010. If the above referenced impact amounts are revised, then this mitigation acceptance letter will no longer be valid and a new mitigation acceptance letter will be required from DMS.
