Review of your application revealed it lacking necessary information required for makine an informed permit decision.'The permit application \vas~ deficient in the following areas: The application has no site plan that displays the proposed fill'superirtiposed_onto;,th'etNatural'resources being impacted. Please provide an accurate (to scale with North Arrow)'~site plan that shows all protected wetlands, waters, and buffers, and the proposed impacts to those resources. No impacts to Zone 2 protected buffers are presented in [he application. Any activity that places rip rap along the stream channel will undoubtedly impact Zone 1 and Zone 2. The Zone impacts are presented in the application. However, accessine Zone I to place the rip rap will require access through Zone 2 of the protected buffers. Please provide appropriate mapping and quantities of anticipated impacts. . , y. _ ... Therefore, pursuant to I SA NCAC ZH .0~07(a)(5) and liA NCAC 2B .0259(8)(b), we will have to place [he permit application on hold until we are supplied the necessary information. Furthermore, until the information is received by the NC Division of Water Quality, we request (by copy of this letter) that the US Army Corps of Engineers place the permit application on hold. Hopefully, we can work together to expedite the processing of your permit application. If you hare am questions or require additional information, please contact John Hennessy at 9I9-7335694. R.

Army Corps of Engineers Raleigh Regulatory Field Office 6508 Falls of the Neuse Road, Suite 120 Raleigh, NC 27609 ®~ 0 2 6 ~) Attention: Ms. Jean B. Manuele NCDOT Coordinator Subject: Proposed Stream Bank Stabilization at Bridge #223, on I-9S over the Swift Creek, in Nash County. State Project No. 5.3232 (DWQ Minor Permit Fee $200) The North Carolina Department of Transportation (NCDOT) proposes to stabilize existing eroded str@am banks along the Swift Creek, near the existing Bridge # 223, on I- 09S NBL. The purpose of this letter is to provide notification to the U. S. Army Corps of Engineers (COE) under Nationwide Permit (NWP) #13, Bank Stabilization, and under NWP #3, Maintenance Activities. This letter shall also provide courtesy notification to the North Carolina Department of Environment and Natural Resources (NCDENR) Division of Water Quality (DWQ) according to concurrence requirements for Water Quality Certification # 3258. Impacts to Waters of the United States The proposed stabilization project will require minimal impacts to waters of the United States in the Tar River Basin. The minimum necessary amount of riprap will be placed adjacent to the existing bridge bents in order to protect them from erosive scour during high water events. Currently a low and eroded scour hole, with an approximate elevation above the ordinary high water mark, surrounds the bridge bents. Eroding riverbanks with which currently have 1: I slopes will be reshaped and stabilized with coir fabrics, stakes and riprap. The total length of the project will be less than 500 feet and will require less than one cubic yard per linear foot placed along the bank below the plane of the ordinary high water mark, on average. Division 4, PO Box 3165, Wilson, NC 27895-3165 p~YM~N~ Phone: (252) 237-6164 Fax: (252) 234-6174 RECI`1~~E~ Waters of the U.S. Mitigation Avoidance: All wetlands or surface waters not affected by the project will be protected from unnecessary encroachment. No staging of construction equipment or storage of construction supplies will be allowed in or near wetlands or surface waters. Minimization: Sedimentation and erosion control Best Management Practices for the protection of wetlands and surface waters will be enforced during project construction. Continued coordination will occur with maintenance forces and the Environmental Officer during construction to minimize impacts to waters of the U. S. at these sites. Compensatory Miti atg ion: Construction of the project will result in only minimal impacts to waters of the U. S. Impacts have been minimized to the maximum extent possible during this stabilization project. Riparian Buffer Impacts The proposed streambank stabilization project involves work within Zone 1 of a river that is subject to the Tar/Pamlico Riparian Buffer Rule. According to the Table of Uses (15A NCCAC 02B.0233 (6)) in the rule, streambank stabilization is allowable with notification. Dewatering The NCDOT proposes to temporarily dewater the work zone in the immediate vicinity of the. proposed project. This will involve the temporary placement of sheet metal cofferdams, or silt curtains azound the base of the slopes being stabilized, in order to minimize temporary increases in turbidity due to construction. Permit Issues The purpose of this letter is to provide notification under Section 404 Nationwide Permit (NWP) 3, Maintenance Activities, for the placement of additional riprap in waters of the U.S. Notification to the COE for the use of NWP 13, streambank Stabilization, is provided as a courtesy for this project, as the bank stabilization activity does not exceed 500 linear feet. Also, courtesy notification to the North Carolina division of Water Quality (NCDWQ) for Section 401 Water Quality Certificate (WQC) No. 3258 is provided for this project. NCDOT will comply with all conditions associated with the applicable NWP and WQC. Additionally, the purpose of this'letter is to request authorization under a Section 404 NWP 33 to temporarily dewater the immediate work zone during the stabilization project. The 401 WQC No. 3114 (which corresponds to NWP 33) does not require written concurrence from the NCDWQ as NCDOT intends to comply with conditions for the WQC. Mussels Tim Savidge of NCDOT Project Development and Environmental Assessment Branch conducted visual and tactile search for freshwater mussels on November 6, 2000. No live mussels were found in the immediate vicinity of the bridge and project work area, or within 500 feet downstream of the proposed project area. Based on this survey, and the -ack of suitable habitat in the project area, NCDOT believes that the proposed action is not likely to affect any federally endangered species. Temporary impacts to the stream channel will be the minimum necessary to effect the repairs, and all appropriate sediment and erosion control measures will be utilized. Temporary impacts to the riparian buffer will not exceed 1500 square feet and any vegetation removed will be restored within six months. a Summary NCDOT proposes to stabilize less than 500 feet of eroded riverbank and repair erosive scour damage in the vicinity of Bridge #223 on the Swift Creek in Nash County: The project is located in the Tar/Pamlico River Basin. Impacts associated with stream bank stabilization are allowable with notification under the Tar/Pamlico Riparian Buffer Rule. The NCDOT asks that the dewatering of the work zone be authorized under a Section 404 NWP 33. The NCDOT will adhere to all applicable Section 404 NWP's and Section 401 WQC's conditions.

Mitigation DWQ - In accordance with ISA NCAC 2H .0500, mitigation may be required by the NC Division of Water Quality for projects involving greater than or equal to one acre of impacts to freshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial streams. USACE - In accordance with the Final Notice of Issuance and Modificatioh of Nationwide Permits, published in the Federal Register on Mazch 9, 2000, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment aze minimal. Factors including size and type of proposed impact and function and relative value of the impacted aquatic resource will be considered in determining acceptability of appropriate and practicable mitigation as proposed. Examples of mitigation that may be appropriate and practicable include, but are not limited to: reducing the size of the project; establishing and maintaining wetland and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of aquatic resource functions and values by creating, restoring, enhancing, or preserving similar functions and values, preferable in the same watershed. If mitigation is required for this project, a copy of the mitigation plan must be attached in order for USACE or DWQ to consider the application complete for processing. Any application lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as incomplete.
