DANIEL SMITH Director North Carolina Division of Water Resources Transportation Permitting Unit In-Field Minor 401 Water Quality Certification, Buffer Certification and Isolated Water Permit Modification Project Name/TIP Project No: US 158 widening R/1015 Date: 4/29/21 DOT Division: 1 County: Northampton DWR Project No./Permit Type: 20190230 v.5/IP DOT Staff: Paul Williams DWR Staff: Garcy Ward ACE Staff: DWR Regional Office: Washington Modification Description: NCDOT proposes to relocate approximately 30 linear feet of a secondary stream and modify the alignment of the lateral ditch, all at Site 7. The stream relocation 111/Ould redirect the stream flow from the fill slope to the inlet of the previously authorized culvert.The realigned lateral ditch 111/Ould impact less jurisdictional wetlands and improve the flow pattern into the jurisdictional stream. The stream relocation 111/Ould also necessitate the placement of riprap on the primary stream bank for bank stabilization. Riprap 111/Ould also be placed in the stream bottom at the inlet of the culvert to prevent headcutting in the primary stream channel.The stream bottom riprap 111/Ould have a layer of native soil placed on top.These modifications 111/Ould result in a reduction of 0.01 acres of excavation in wetlands,a reduction of 28 linear feet of temporary stream impact, an increase of 0.01 acres of mech. clearing in wetlands, and an increase of 28 linear feet of permanent stream impact.All as shown in the attached revised permit drawing and impact table dated 4/22/2021.

This in-field modification is valid only if issued by an authorized agent of the Division of Water Resources, Transportation Permitting Unit 1 This in-field modification authorizes the NCDOT to relocate a small section of secondary stream channel and relocate a section of a proposed lateral ditch at Site 7. in Northampton County. The project shall be constructed as described in the Modification Description and Sketch on Page 1 of this document dated 4/29/21 to improve/construct the culvert at at Site 7. The approved design is that described in the Modification Description and Modification Sketch on Page 1 of this document dated 4/29/21. Any further changes to the original Water Quality Certification dated June 4, 2019 may require a formal written modification request. The description of the proposed action provides adequate assurance that the proposed action in the Neuse River Basin in conjunction with the proposed development will not result in a violation of applicable Water Quality Standards and discharge guidelines. Therefore, the State of North Carolina certifies that this activity will not violate the applicable portions of Section 301, 302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance with the application and conditions hereinafter set forth.
