EASLEY LYNDO TIPPET'S GOVERNOR SECRETARY March 3, 2006 U.S. Army Corps of Engineers Raleigh Regulatory Field Office 6508 Falls of the Neuse Road, Suite 120 060375 Raleigh, NC 27609 Attention: Mr. Eric Alsmeyer, NCDOT Coordinator Subject: Proposed maintenance improvements to structures conveying an unnamed tributary to Walkers Creek on US 158 in Warren County. WBS element 511.109311, STAT 10# 9800766. The North Carolina Department of Transportation (NCDOT) proposes to replace two structures conveying an unnamed tributary to Walkers Creek on US 158 in Warren County (Figures 1 - 2). Impacts to Waters of the United States The project crosses a perennial stream, an unnamed tributary to Walkers Creek [NCDENR-DWQ Index No. 28-79-25-2, Best Usage Classification C NSW; HUC 03020102] (Figure 3) in the Tar-Pamlico River Basin. The existing structures that convey the creek are 2 @ 54-inch corrugated metal pipes that are 83 feet long with a headwall at the inlet (see Photographs 1-3). The proposed structure is a 103-inch x 71-inch corrugated metal pipe arch that is 100-feet long. Ten feet of rip rap will be placed along the creek banks both upstream and downstream of the structure. During the construction of the project, the NCDOT proposes to temporarily dewater the work zone for approximately 2 weeks. This will involve the temporary placement of sheet piling at the construction limits. To maintain water flow during construction, water upstream of the sheet piling will be temporarily pumped out by a hose and conveyed downstream of the construction activity where it will be allowed to filter through vegetation before flowing into the stream. The effluent from the work area will be pumped into a prefabricated silt bag allowing water to slowly filter out of the bag in a dispersed matter and the sediment to be captured in the bag. Once the stream has been dewatered, the pipes will be replaced. The sheet piling will be removed after construction. The existing structures are rusted, undersized, and have resulted in a large blowhole at the outlet. Please note that the outlet of the proposed structure will be located inside the limits of Division 5, 2612 N. Duke Street, Durham, NC 27704 Phone: (919) 560-6081 Fax: (919) 560-3371 this ?blowhol(c making it impractical to bury the pipe one foot in the stream bed that now exists at the bottom of the blowhole. Therefore, NCDOT will set the invert of the pipe one foot below the "theoretical" streambed elevation taken from projection of the streambed grade from further down stream back into the blowhole. NCDOT hydraulics unit has indicated that the increase in diameter of the proposed structure will reduce the water velocity and cause sediment to accumulate in the blowhole and eventually fill up over time to match the surrounding stream bed. Permanent impacts at the site associated with the replacement of the structure involve a total of 17 feet of surface water fill for installation of the longer structure and the placement of 20 feet of rip rap along the streambanks to protect the structure. Temporary concurrent impacts will include the dewatering of 37 feet of stream. Riparian Buffer Construction at this site involves a road crossing of a stream that is subject to the Tar-Pamlico River Riparian Buffer Rules. The unnamed tributary to Walkers Creek at Site 1 is depicted on the most recent version of the Macon (USGS 1970) topographic quadrangle (Figure 1). Construction impacts at this site total 2,504 ft2 in Zone 1 and 0 ft2 in Zone 2 (totaling 37 linear feet of riparian buffer impacts). Please note that impacts associated with installation of the sheet piling and special stilling basin (silt bag) are included as part of these totals. Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT. Waters of the U.S. Mitigation Avoidance: All wetlands and 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 wetlands or near surface waters. Minimization: The side slopes have been steepened to the extent possible at jurisdictional sites. Strict enforcement of 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 these sites. Compensatory Mitigation: All compensatory mitigation requirements will be left to the discretion of the regulatory review agencies. Protected Species Plants and animals with federal classifications of Endangered, Threatened, Proposed Endangered and Proposed Threatened are protected under provisions of Section 7 and Section 9 of the Endangered Species Act. As of March 03, 2006, the dwarf wedgemussel (Alasmidonta heterodon) and the Tar spinymussel (Elliptio steinstansana) are listed as federally protected species in Warren County. A mussel survey was conducted at this crossing by biologists with Alderman Environmental Services, Inc. on February 25, 2006 with a finding of no effect for federally protected species. Additionally, a review of the Natural Heritage Program database (last updated January 2006) revealed no occurrences of protected species within the project area. Therefore, based on lack of suitable habitat observed during the site visit and the NHP database review, biological conclusions of No Effect have been rendered for each species. Summary The NCDOT proposes to replace the existing structures with one larger and longer sized pipe. Permanent impacts at the site associated with the replacement of the structure involve a total of 17 feet of surface water fill for installation of the longer structure and the placement of 20 feet of rip rap along the streambanks to protect the structure. Temporary concurrent impacts will include the dewatering of 37 feet of stream. The sheet piling will be removed after construction. Riparian buffer impacts at Site 1 associated with this maintenance activity total 2,504 ft2 in Zone 1 and 0 ft2 in Zone 2 (totaling 37 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT. Application is hereby made for a Department of the Army Section 404 Nationwide Permit (NWP) 3, NWP 33, and NCDENR-DWQ Section 401 Water Quality Certification (WQC) No. 3494, WQC No. 3366, and riparian buffer authorization for above-described activities. An automated payment procedure has been implemented between the NCDOT and NCDENR-DWQ. This procedure will enable the Division to apply for the 401 WQC without submitting a check for this permit application. This procedure will provide payment to the NCDENR-DWQ by charging the permit application fee of $200.00 directly to the appropriate NCDOT WBS element 513.109311, STAT IO# 9800766. A pre-construction notification is attached with this request. If you have any questions or need additional information, please contact Mr. Chris Murray at (919)560-6851. Sincerel , Jon G. ce, P.E.

Strict enforcement of Best Management Practices for the protection of wetlands and surface waters will be enforced during construction. Only the smallest amount of fill necessary to complete the project will be placed in waters of the United States. VIII. Mitigation DWQ - In accordance with 15A 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 Modification of Nationwide Permits, published in the Federal Register on January 15, 2002, mitigation will be required when necessary to ensure that adverse effects to the aquatic environment are 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 Page 5 of 8 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 NCEEP concurrence shall be placed on hold as incomplete. An applicant may also choose to review the current guidelines for stream restoration in DWQ's Draft Technical Guide for Stream Work in North Carolina, available at httl2:Hh2o.enr.state.ne.us/ncwetlands/strmgide.litml. 1. Provide a brief description of the proposed mitigation plan. The description should provide as much information as possible, including, but not limited to: site location (attach directions and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet) of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view, preservation mechanism (e.g., deed restrictions, conservation easement, etc.), and a description of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. All compensatory mitigation requirements will be left to the discretion of the re latory review agencies. 2.
