ERIC BOYETTE GOVERNOR SECRETARY March 24, 2020 U.S. Army Corps of Engineers Regulatory Field Office 151 Patton Avenue, Room 208 Asheville, NC 28801-5006 ATTN: Ms. Lori Beckwith, NCDOT Coordinator Subject: Request for Revision to Section 404 Nationwide Permit, Section 401 Water Quality Certification for the Proposed Replacement of Bridge No. 8 on NC 194 over the North Fork New River in Ashe County; TIP BR-0002, Division 11, Debit $240 from WBS Element 67002.1.1 Reference: Section 404 Permit, (Action ID SAW-2019-02373), issued February 11, 2020 Section 401 Water Quality Certification (NCDWR Project No. 20191658), issued December 19, 2019 Ms. Beckwith: The NCDOT Geotechnical Unit has performed additional scour calculations that prompted changes to the retaining wall located parallel to Buffalo Creek. This resulted in to changes to the pervious permitted design. The retaining wall, established to avoid impacts to Buffalo Creek, will shift five additional feet away from the stream. A new corrugated steel pipe (CSP) that was previously proposed to exit through the wall and discharge into Buffalo Creek, will now be shifted eastward, outside of the wall area. This will allow the pipe to outlet approximately 9 feet further away from Buffalo Creek than the original design. Impact Changes at Site 2 Permanent impacts to Buffalo Creek reduced by 3 if (from 18 if to 15 If) required for the keyed -in bank stabilization in Buffalo Creek. Temporary impacts have increased 31 if (from 11 if to 42 If). This is the result of the need to remove the 18" CMP that was going to be replaced and discharged through the wall. Mailing Address: Telephone: (919) 707-6000 Location: NC DEPARTMENT OF TRANSPORTATION 1000 BIRCH RIDGE DRIVE ENVIRONMENTAL ANALYSIS UNIT Customer Service: 1-877-368-4968 RALEIGHNC 27610 1598 MAIL SERVICE CENTER Website: www.ncdot.gov RALEIGH NC 27699-1598 Total Project Impacts This Site 2 revision decreases the total permanent project impact by 3 if (from 41 if to 381f) and increases the total temporary impacts by 31 if (from 123 if to 1541f (0.07 ac to 0.08 ac)). Pursuant to the permit issued on February 11, 2020, the 181f of impacts at Site 2 were not considered Loss of Waters of the US and did not require mitigation. Since the impact type remains the same, NCDOT proposes no changes to the mitigation requirements for this project. Please see enclosed copies of the Revised Stormwater Management Plan and Revised Permit Drawings (Sheet 2 of 7, Sheet 3 of 7 and Sheet 7 of 7). Request to Remove Hellbender Condition in the 401 Permit Condition Number 3 from the NCDWR Water Quality Certification states: This project has the potential to impact hellbender salamanders and trout waters. No construction activities shall begin until the NCWRC makes a determination regarding moratoria. Should the NCWRC determine that a moratorium is applicable then the requirements of any moratorium(s) shall be a condition of this 401 Certification. If the NCDOT does not wish to honor the moratorium, then a written modification shall be submitted. [15A NCAC 02H. 0506(b) (2) and 15A NCAC 04B.0125 Pursuant to the instructions in the condition, NCDOT requests that this commitment be excluded from the Conditions of the 401 Certification. Based on longstanding coordination agreements with NCDOT and State and Federal Agencies, NCDOT adheres to moratorium requests for trout and anadromous fish, as well as for federally protected species listed as Threatened or Endangered. In 2019, the US Fish and Wildlife Service determined that the hellbender would not be listed as federally protected for North Carolina. NCDOT will retain the commitment to use Design Standards for Sensitive Waters for this project. These Design Standards will ensure the most stringent of sedimentation and erosion controls and should prevent any sedimentation impact on the hellbender. Section 404: Application is hereby made for a revision to the USACE 404 Permit as required for the above - described activities. Section 401: We are hereby requesting a revision to the 401 Water Quality Certification from the N. C. Division of Water Resources for the above -described activities and removal of Condition Number 3. A copy of this permit revision and its distribution list will be posted on the NCDOT Website at: http://connect.ncdot.gov/resources/Environmental. If you have any questions or need additional information, please call Jeff Hemphill at (919) 707-6126. Sincerely, cW, � Philip S. Harris I1I, P.E., C.P.M.

Typical Cross Section Description: The proposed cross-section is 2 lane undivided, 12' wide lanes with 8' shoulder (11' in guardrail locations). The clear roadway width of the proposed bridge is 35'. The clear roadway width is 23', while the existing bridge is 26'. The typical section is 2 lane undivided with grass shoulders. Annual Avg Daily Traffic (veh/hr/day): Design/Future: 4100 Year: 2040 Existing: 4010 Year: 2020 General Project Narrative: (Description of Minimization of Water Quality Impacts) Project will replace existing 6 span bridge with a 3 span 63" pre -stressed concrete girder bridge with 4' deep caps with 1.5:1 spill through abutments. The span arrangement will be 1 @ 85', 1 @ 1 10'and 1 @ 85'. Proposed bents will be located outside of the stream and the existing bents will be removed from the stream. Deck drains will be placed on the bridge where they do not discharge over water. One SR and one driveway will be realigned due to site distances of the proposed bridge. Construction will be staged to maintain traffic on site. Existing drainage patterns will be maintained. 2:1 roadway fill slopes are used to minimize footprint of the overall project. Ditches will be vegetated where possible. Riprap pads are used at pipe outlets to dissipate energy and prevent erosion. A retaining wall was included to prevent significant impacts to Buffalo Creek (10- 2-20) which is a NCDWQ Trout Stream. 16.
