EASLEY LYNDO TIPPETT y~cy GOVERNOR SECRETARY April 19, 2007 U.S. Army Corps of Engineers Raleigh Regulatory Field Office 6508 Falls of the Neuse Road, Suite 120 Q ~~ Raleigh, NC 27609 Attention: Mr. Eric Alsmeyer NCDOT Coordinator Subject: Proposed replacement of Bridge No. 123 on SR 1407 (Rueben Hart Road) over an unnamed tributary to Little Johnson Creek in Granville County. WBS Element No. SB.20391 The North Carolina Department of Transportation (NCDOT) proposes to replace Bridge No. 123 over an unnamed tributary to Little Johnson Creek on SR 1407 (Rueben Hart Road) in Granville County (Figures 1 and 2). The existing structure is a single span bridge (1 @ 26 feet with timber vertical end abutments) constructed in 1955 that has a sufficiency rating of 48. The replacement structures are 2 @ 142 inch x 91 inch corrugated metal pipe arches (CMPAs) that are 60 feet long. Please note that two unnamed tributaries to Little Johnson Creek converge at the western (downstream) edge of the bridge (see Photograph 1~ An upland knoll is located between the two tributaries prior to the bridge. A portion of this knoll will be excavated to allow the convergence of the two tributaries immediately upstream of the replacement structures. The knoll must be excavated to the approximate depth of the invert of the replacement structures. Please note that bedrock features are evident in the stream channels, which may preclude the required burial of the CMPAs at the site. Impacts to Waters of the United States The removal of the existing structure and subsequent installation of the CMPAs will result in impacts to the unnamed tributaries to Little Johnson Creek (NCDENR-DWQ Index No. 23-2-7-3, Best Usage Classification C, HUC 03010102) in the Roanoke River Basin. Bride Demolition Removal of the existing structure will be completed without dropping components into the stream. Best management practices for bridge demolition and removal will be adhered to during the life of the project. Division 5, 2612 N. Duke Street, Durham, NC 27704 Phone: (919) 560-6081 Fax: (919) 560-3371 2 Permanent Impacts Installation of the CMPAs will result in impacts to unnamed tributaries to Little Johnson Creek. These impacts are summarized below: • 40 linear feet of impact (fill in SW) to UT to Little Johnson Creek after convergence of the two UTs. • 20 linear feet of impact (fill in SW) to the northern UT to Little Johnson Creek prior to the convergence of the two tributaries near the western (downstream) edge of the bridge. • 23 linear feet of impact (fill in SW) to the southern UT to Little Johnson Creek prior to the convergence of the two tributaries near the western (downstream) edge of the bridge. Bank stabilization activities will result in impacts to unnamed tributaries to Little Johnson Creek. These impacts are summarized below: • l5 linear feet of bank impact along UT to Little Johnson Creek at the outlet of the replacement structures. • 21 linear feet of bank impact along the northern UT to Little Johnson Creek at the inlet of the northern-most replacement structure. • 30 linear feet of bank impact along the southern UT to Little Johnson Creek at the inlet of the southern-most replacement structure. 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 149 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 tributaries to Little Johnson Creek cannot be avoided. The NCDOT hydraulics unit has determined that the proposed CMPAs are suitable replacements for the existing bridge structure. Minimization: The proposed rip rap at the inlet and outlet of the structures has been minimized as much as possible while providing the required long-term stability. Compensatory Mitigation: Compensatory mitigation will be provided at the request of the regulatory 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 ESA. As of April l9, 2007, the bald eagle (Haliaeetus leucocephalus), dwarf wedgemussel (Alasmidonta heterodon), harperella (Ptilimnium nodosum) and smooth coneflower (Echinacea laevigata) are listed as federally protected species in 3 Granville County. Suitable habitat for harperella and smooth coneflower are not present at the site. Large open water systems that are required for the bald eagle are also not present at the site. ` A mussel survey was conducted at the site on February 27, 2007 by NCDOT biologists Karen Lynch and Logan Williams. Although suitable habitat for common mussels is present in the stream at the site, the dwarf wedgemussel was not found during the survey and has never been found in the Roanoke River Basin. It can be concluded that construction of the project will have No Effect on the dwarf wedgemussel. Summary The NCDOT proposes to replace structurally deficient Bridge No. 123 with 2 @ 142 inch x 91 inch CMPAs that are 60 feet long. Application is hereby made for a Department of the Army Section 404 Nationwide Permit (NWP) 14 and NCDENR-DWQ Section 401 Water Quality Certification (WQC) No. 3627. 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 NCDWQ by charging the permit application fee directly to the appropriate NCDOT WBS Element No. SB.20391. A pre- construction notification, photograph and permit drawing are attached with this request. If you have any questions or need additional information, please contact Mr. Chris Murray at (919) 560-6851. Sincerely, ~. ~~~-- J. W. Bowman, P.E.

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. Avoidance• Construction of the proiect cannot avoid impacts to waters of the United States. The NCDOT hydraulics unit has determined that the CMPAs are suitable replacements for the existing bride structure. Minimization• The proposed rip rap at the inlet and outlet of the structures 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 PlanningLand Design Manual" during_desi~n and construction phases of the project. Page 6 of 9 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 of the current site conditions and proposed method of construction. Please attach a separate sheet if more space is needed. Mitigation for the project will be provided if requested by the regulatory encies.
