EASLEY GOVERNOR August 2, 2007 U.S. Army Corps of Engineers Raleigh Regulatory Field Office 6508 Falls of the Neuse Road, Suite 120 Raleigh, NC 27609 Attention: Mr. Eric Alsmeyer NCDOT Division 5 Coordinator LYNDO TIPPETT SECRETARY 071355 Subject: Proposed replacement of existing structure on SR 1518 (Stewart Farm Road) conveying an unnamed tributary to Weaver Creek in Vance County. WBS Element No. SB.2091 The North Carolina Department of Transportation (NCDOT) proposes to replace the existing structure on SR 1518 (Stewart Farm Road) conveying an unnamed tributary to Weaver Creek in Vance County (Figure 1). The existing structure is a 60 inch corrugated metal pipe (with concrete headwall at the inlet) that is 36 feet long (Photograph 1). The proposed replacement structure is a 60 inch corrugated metal pipe that is 60 feet long. Impacts to Waters of the United States The removal of the existing structure and subsequent installation of the new pipe will result in impacts to the unnamed tributary to Weaver Creek (NCDENR-DWQ Index No. 28-78-1-7, Best Usage Classification C NSW, HUC 03020101) in the Tar-Pamlico River Basin. Permanent Impacts Installation of the replacement structure will result in impacts to the unnamed tributary to Weaver Creek. This impact is summarized below: • 24 linear feet of impact (fill in SW). Bank stabilization activities (with rip rap) will result in impacts to the unnamed tributary to Weaver Creek. These impacts are summarized below: • 15 linear feet of bank impact at the inlet of the replacement structure. l O linear feet of bank impact at the outlet of the replacement structure. Placement of roadway fill associated with the pipe installation and installation of rip rap at the pipe outlet will result in impacts to a palustrine forested wetland: • 0.01 acre fill in wetland. Division 5, 2612 N. Duke Street, Durham, NC 27704 Phone: (919) 560-6081 Fax: (919) 560-3371 2 Temporary Impacts The NCDOT proposes to temporarily dewater the work zone during construction for approximately four weeks. This will involve the temporary placement of sand bags at the construction limits of the project. This will result in 49 linear feet of concurrent stream impacts. To maintain water flow during construction, water upstream of the sand bags 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 manner and the sediment to be captured in the bag. The temporary sand bags will be removed after construction. Waters of the U.S. Mitigation Avoidance: Permanent impacts to the unnamed tributary to Weaver Creek and the wetland cannot be avoided.. The existing pipe structure is rusted. The NCDOT hydraulics unit has determined that the proposed CMPA is a suitable replacement for the existing structure. Minimization: The proposed rip rap at the inlet and outlet of the structure has been minimized as much as possible while providing the required long-term stability. All construction impacts at the inlet and outlet of the replacement structure have been minimized. Compensatory Mitigation: Compensatory mitigation will be provided for stream and wetland impacts. The Department proposes to provide 1:1 mitigation for the additional piped impacts to the stream. We suggest that the stream is perennial, but prone to drying up during times of drought. The Department also proposes to provide mitigation at a 1:1 ration for the 0.01 acres of wetland impact at the site. All compensatory mitigation requirements are assimilated on a quarterly basis and provided to the Ecosystem Enhancement Program (EEP). Riparian Buffer Construction at this site involves the road crossing of a stream that is subject to the Tar-Pam Riparian Buffer Rules. The stream is depicted on the most recent version of the Vicksboro (USGS 1970) topographic quadrangle (Figure 1) and Soil Survey of Vance County (USDA-SCS, 1977). Construction impacts at this site total 1,697 square feet in Zone 1 and 0 square feet in Zone 2 (totaling 49 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is ALLOWABLE. Temporary erosion control measures will be installed as required within the permitted buffer footprint. 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 ESA. As of August 2, 2007, the dwarf wedgemussel (Alasmidonta heterodon) is listed as federally protected species in Vance County. A mussel survey was conducted at the site on July 12, 2007 by NCDOT biologists Jason Mays and Logan Williams. They determined that suitable habitat for dwarf wedgemussel is not present at the site due to lack of water in the channel. 3 Summary Application is hereby made for a USACE Section 404 Nationwide Permit No. 14, NCDENR-DWQ Section 401 Water Quality Certification (WQC) No. 3627 and 3634 and riparian buffer authorization. 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 directly to the appropriate NCDOT WBS Element No. SB.2091. A pre- construction notification, photograph and permit drawing are attached with this request.

Wetland and stream evaluation and delineation forms should be included as appropriate. Photographs may be included at the applicant's discretion. If this proposed impact is strictly for wetland or stream mitigation, list and describe the impact in Section VIII below. If additional space is needed for listing or description, please attach a separate sheet. Provide a written description of the proposed impacts: Construction of the project will result in the following. impacts: Permanent Impacts Installation of the replacement structure will result in impacts to the unnamed tributary to Weaver Creek. This impact is summarized below: • 24 linear feet of impact (fill in SW). Page 3 of 9 Bank stabilization activities will result in impacts to the unnamed tributary to Weaver Creek. These impacts are summarized below: • 15 linear feet of bank impact at the inlet of the replacement structure. • l O linear feet of bank impact at the outlet of the replacement structure. Placement of roadway fill associated with the pipe installation and installation of rip rap at the pipe outlet will result in impacts to a palustrine forested wetland: • 0.01 acre fill in wetland. Temporary Impacts • Dewatering activities will result in 491iner feet of concurrent stream impacts. 1. Individually list wetland impacts. Types of impacts include, but are not limited to mechanized clearing, grading, fill, excavation, flooding, ditching/drainage, etc. For dams, separately list impacts due to both structure and flooding.

Isolated Waters Do any isolated waters exist on the property? ^ Yes ®No Describe all impacts to isolated waters, and include the type of water (wetland or stream) and the size of the proposed impact (acres or linear feet). Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 7. Pond Creation If construction of a pond is proposed, associated wetland and stream impacts should be included above in the wetland and stream impact sections. Also, the proposed pond should be described here and illustrated on any maps included with this application. Pond to be created in (check all that apply): ^ uplands ^ stream ^ wetlands Describe the method of construction (e.g., dam/embankment, excavation, installation of draw-down valve or spillway, etc.): N/A Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): N/A Current land use in the vicinity of the pond: N/A Size of watershed draining to pond: N/A Expected pond surface area: N/A VIII. Impact Justification (Avoidance and Minimization) Specifically describe measures taken to avoid the proposed impacts. It may be useful to provide information related to site constraints such as topography, building ordinances, accessibility, and financial viability of the project. The applicant may attach drawings of alternative, lower-impact site layouts, and explain why these design options were not feasible. Also discuss how impacts were minimized once the desired site plan was developed. If applicable, discuss construction techniques to be followed during construction to reduce impacts. Page 5 of 9 Avoidance: Construction of thepro~ect cannot avoid impacts to waters of the United States. The NCDOT l~draulics unit has determined that the CMP is a suitable replacement for the existing structure. Minimization• The proposed rip rap at the inlet and outlet of the structure has been minimized as much as possible while providing the required long-term stability. NCDOT will implement best mana eg_ ment practices for the protection of surface waters in accordance with the most recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual" during design and construction phases of the project. Wetland impact is limited to extent of fill slope and a small impact associated with installation of rip rap on streambank at outlet of structure. IX. 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 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 http://h2o. enr.state.nc.us/ncwetlands/strmgide.html. 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 Page 6 of 9 of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. The Department proposes to provide 1:1 mitigation for the additional piped impacts to the stream (24 linear feet of warm water restoration in HUC 03020101). We suggest that the stream is perennial, but prone to drying up during times of drought. The Department also proposes to provide mitigation at a 1:1 ration for the 0.01 acres of wetland impact at the site. All compensatory miti ation requirements are assimilated on a quarterly basis and provided to the Ecosystem Enhancement Pro ram EEPZ 1. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP). Please note it is the applicant's responsibility to contact the NCEEP at (919) 715-0476 to determine availability, and written approval from the NCEEP indicating that they are will to accept payment for the mitigation must be attached to this form. For additional information regarding the application process for the NCEEP, check the NCEEP website at http://h2o.enr.state.nc.us/wrp/index.htm. If use of the NCEEP is proposed, please check the appropriate box on page five and provide the following information: Amount of stream mitigation requested (linear feet): 24 Amount of buffer mitigation requested (square feet): N/A Amount of Riparian wetland mitigation requested (acres): 0.01 Amount ofNon-riparian wetland mitigation requested (acres): N/A Amount of Coastal wetland mitigation requested (acres): N/A X. Environmental Documentation (required by DWQ) 1. Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ® No ^ 2. If yes, does the project require preparation of an environmental document pursuant to the requirements of the National or North Carolina Environmental Policy Act (NEPA/SEPA)? .Note: If you are not sure whether a NEPA/SEPA document is required, call the SEPA coordinator at (919) 733-5083 to review current thresholds for environmental documentation. Yes ^ No 3. If yes, has the document review been finalized by the State Clearinghouse? If so, please attach a copy of the NEPA or SEPA final approval letter. Yes ^ No ^ XI. Proposed Impacts on Riparian and Watershed Buffers (required by DWQ) It is the applicant's (or agent's) responsibility to determine, delineate and map all impacts to required state and local buffers associated with the project. The applicant must also provide justification for these impacts in Section VII above. All proposed impacts must be listed herein, and must be clearly identifiable on the accompanying site plan. All buffers must be shown on a map, whether or not impacts are proposed to the buffers. Correspondence from the DWQ Regional Office may be included as appropriate. Photographs may also be included at the applicant's discretion. Page 7 of 9 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Meuse), 1 SA NCAC 2B .0259 (Tar-Pamlico), 15A NCAC 02B .0243 (Catawba) 15A NCAC 2B .0250 (Randleman Rules and Water Supply Buffer Requirements), or other (please identify )? Yes ® No ^ 2. If "yes", identify the square feet and acreage of impact to each zone of the riparian buffers. If buffer mitigation is required calculate the required amount of mitigation by applying the buffer multipliers. Site 1 Zone* Impact (s uare feet Multiplier Required Miti ation I 1,697 sf 3 (2 for Catawba) N/A 2 0 sf 1.5 N/A Total 1,697 st * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additiona120 feet from the edge of Zone 1. 3. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Riparian Buffer Restoration /Enhancement, or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or .0244, or .0260. N/A XII. Stormwater (required by DWQ) Describe impervious acreage (existing and proposed) versus total acreage on the site. Discuss Stormwater controls proposed in order to protect surface waters and wetlands downstream from the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. There is approximately <0.1 acre existing impervious surface within the 0.2 acres proiect site. No additional impervious surface is roposed with this project. XIII. Sewage Disposal (required by DWQ) Clearly detail the ultimate treatment methods and disposition (non-discharge or discharge) of wastewater generated from the proposed project, or available capacity of the subject facility. This project will not generate wastewater. XIV. Violations (required by DWQ) Is this site in violation of DWQ Wetland Rules (15A NCAC 2H .0500) or any Buffer Rules? Yes ^ No Is this anafter-the-fact permit application? Yes ^ No Page 8 of 9 XV. Cumulative Impacts (required by DWQ) Will this project (based on past and reasonably anticipated future impacts) result in additional development, which could impact nearby downstream water quality? Yes ^ No If yes, please submit a qualitative or quantitative cumulative impact analysis in accordance with the most recent North Carolina Division of Water Quality policy posted on our website at http://h2o.enr.state.nc.us/ncwetlands. If no, please provide a short narrative description: This bridge maintenance project will not result in additional development. XVI.
