TROGmN, III SECRETARY Subject: Request for Modification of Section 404 Individual Permit and Section 401 Water Quality Certification for the U-2579B Section of the Winston-Salem Northern Beltway, from US 158 to I-40 Business/US 421, Forsyth County, Division 9, WBS 34839.2.10 References: Section 404 Individual Permit — Action ID No. SAW-2009-03183, issued June 17, 2014 and modifications issued July 2, 2014, February 21, 2019, and Section 404 Individual Renewal/ ATF Permit Modification, October 17, 2019 Section 401 Water Quality Certification — NCDWR Project No. 2014090 issued April 11, 2014 and modifications issued July 18, 2014, December 17, 2018, and Section 401 Water Quality Certification Renewal/ATF issued October 15, 2019 Dear Madam: The North Carolina Department of Transportation (NCDOT) requests a Permit Modification for the Winston -Salem Northern Beltway Eastern Section from US 158 to I-40, B Section of the U-2579 TIP. This project is currently under construction. This modification request will include revised impacts to Smith Creek (Sites 28 and 23), new impacts to UT Smith Creek (site 28A), and new impacts to two ponds (sites 28B and 28C). Smith Creek is a parallel stream along this section of the Beltway. Due to multiple large storm events, the original proposed roadway has been destabilized, undermining the fill slopes. To correct this situation, NCDOT had determined that the only option for Smith Creek is to relocate away from the road fill. A culvert option was investigated but the length of the culvert will complicate maintenance and inspections (located under a travel lane), have drainage complications, is cost prohibitive, and overall determined to be structurally unsound.

Pond 1 and Pond 2 will be drained to accommodate the relocation of Smith Creek totaling 7.82 acre of impacts. The total new permanent stream impacts for this modification are 1,736 Linear feet (1,791 LF — 55 LF). The modification of this permit for the relocation of Smith Creek, will now bring the total stream impacts for the U-2579B Section of the W-S Beltway to: 12,480 linear feet of permanent stream impacts 1,570 linear feet of temporary impacts The mitigation for new impacts will be determined when the final plans for the relocated stream are complete. This plan will be submitted to the USACE and NCDWR for determination of credits applicable for the Natural Stream Design (NSD) plans for this stream. Currently the proposed NSD is 2,127 linear feet for Smith Creek (Site 28) and 344 linear feet for UT Smith Creek (Site 28A). Once the credit for NSD has been determined, NCDOT will contact DMS for the balance. Please see the attached revised permit drawings for the relocation of Smith Creek and the corrected permit impact summary sheet. NCDOT is hereby requesting a Modification for this project. If you have any questions, please contact Carla Dagnino at cda nig_nokncdot.gov or (919) 707-6110. Thank you! Sincerely, em Philip S. Harris III, P.E., C.P.M.

Quality Impacts) These Grassed Swales have side slopes that are 3:1 or flatter, with many sode slopes being 6:1. have a velocity during the 2-Year Storm or less than 2 feet per second and have a minimum ditch length equivalent to 100 feet per acre of impervious area. In addition to the Grassed Swales, Preformed Scour Holes and Energy Dissipators are used at several locations. 10/1/2019 - Revised Submittal Modifications to U-2579B were performed and submitted January 2019. These changes include: Stormdrain revisions Proposed 32' 3 @ 8' x 9' RCBC Downstream Extension (Sta. 45+65 -Y4-) Proposed 41' 3 @ 8' x 9' RCBC Upstream Extension (Sta. 45+65 -Y4-) Smith Creek Stream Relocation (Sta. 47+27 to 67+63 -Y4-) UT to Smith Creek Stream Relocation (Sta. 48+60 -Y4-) A permit modification was needed for the revisions mentioned above. Included with this revised SMP are updated pipe sizes and flows of two outlets to Preformed Scour Holes (Sta. 43+00 and 46+00). All other stormwater features (swales, filter strip, energy dissipators, etc.) were not modified by these 2019 revisions and are not included with this modification.
