Division Engineer NCDOT, Division 5 2612 N. Duke Street Durham, NC 27704 Dear Mr. Nance: You have our approval, in accordance with the conditions listed below, for the following impacts for the purpose of secondary road improvements on SR 1723 (Lakeside Drive) in Durham County. Impact Locations Stream Impacts -Permanent Fill Riparian Buffer impacts (Square Feet) ?Llllvua ? ??/ !Site 1 5 1,478 Zone 1 + 959 Zone ite 2 0 2,007 (1,117 Zone 1 + 830 Zone 2) Site 3 0 1,977 (1,496 Zone 1 + 481 Zone 2) The project shall be constructed in accordance with your application dated received May 23, 2005. After reviewing your application, we have decided that the stream impacts and riparian buffer impacts described are covered by General Water Quality Certification Number 3404. This certification corresponds to the Nationwide Permit 14 issued by the Corps of Engineers. This approval is also valid for the Neuse River Buffer Rules (15A NCAC 213 .0233). In addition, you should acquire any other federal, state or local permits before you proceed with your project including (but not limited to) Sediment and Erosion Control, Non-Discharge and Water Supply Watershed regulations. This approval will expire with the accompanying 404 permit, unless otherwise specified in the Water Quality Certification. This approval is valid solely for the purpose and design described in your application (unless modified below). Should your project change, you must notify the DWQ and submit a new application. If the property is sold, the new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total impacts to streams (now or in the future) exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H.0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the conditions listed in the attached certification. 1.) Upon completion of the project, the NCDOT shall complete and return the enclosed "Certification of forma and return itlto tthe Certification has been completed. Un t of the Divis on ofe Completion Formshall complete DWQe when responsible party p Water Quality upon completion of the project. 2.) All stormwater runoff shall be directed to sheetflow through stream buffers at nonerosive velocities, unless approved otherwise by this certification. 3.) During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or One riparian buffers.

Riparian vegetation must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 5.) The dimension, pattern and profile of the stream above and below the crossing should not be modified by widening the stream channel or reducing the depth of the stream. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 6.) Any riprap used must not interfere with thalweg performance and aquatic life passage during low flow conditions. 7.) All mechanized equipment operated near surface waters must be regularly inspected and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 8.) Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 9.) The outside buffer, wetland or water boundary located within the construction corridor approved by this authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this certification. 10.) There shall be no excavation from or waste disposal into jurisdictional wetlands or waters associated with this permit without appropriate modification of this permit. Should waste or borrow sites be located in wetlands or stream, compensatory mitigation will be required since it is a direct impact from road construction activities. 11.) Heavy equipment must be operated from the banks rather than in the stream channel in order to minimize sedimentation and reduce the likelihood of introducing other pollutants into the stream. 12.) Placement of culverts and other structures in waters, streams, and wetlands must be placed below the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow low flow passage of water and aquatic life. Design and placement of culverts and other structures including temporary erosion control measures shall not be conducted in a manner that may result in dis-equilibrium of wetlands or stream beds or banks, adjacent to or upstream and down stream of the above structures. The applicant is required to provide evidence that the equilibrium shall be maintained if requested in writing by DWQ. 13.) If the above condition (#12) is unable to be met, due to bedrock or other limiting features, encountered during construction, please discontinue activities and contact the NCDWQ for directions on how to proceed. 14.) No live or fresh concrete shall come into contact with waters of the state until the concrete has hardened 15.) The presence of equipment in the channels must be minimized. Under no circumstances must rock, sand or other materials be dredged from the wetted stream channel under authorization of this permit, except in the immediate vicinity of the culverts. 16.) All work shall be performed during low or normal flow conditions. 17.) All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1. 18.) A copy of this Water Quality Certification shall be posted on the construction site at all times.

WBS element 5C.032052 The North Carolina Department of Transportation (NCDOT) proposes to upgrade and pave SR 1723 (Lakeside Drive) from SR 1640 (Goodwin Road) to end of maintenance in Durham County (Figures 1-5). Total project length is 0.23 miles. Transportation and highway laws of North Carolina (G.S. 136-44.6, 136-44.7, 136-44.7A, 136-44.8, and 136-44.9) require the NCDOT to develop annual work programs for construction and maintenance of secondary roads. These general statutes specifically set forth requirements for annual construction and paving of existing unpaved roads. Paving of these roads is performed in priority order as established by the NCDOT for each unpaved road within a given county. This number is based on characteristics of each road, including number of homes, schools, churches, businesses, industries, recreational facilities, traffic counts, presence of school bus routes, and value as a thoroughfare. SR 1723 is scheduled to be paved as part of the Secondary Roads Construction Program. Impacts to Waters of the United States Site 1 -- Waters of US Construction at this site will have NO impacts to the unnamed intermittent tributary to Cabin Creek [NCDENR-DWQ Index No. 27-2-21-7, Best Usage Classification WS-IV NSW; HUC 03020201] (Figure 3) in the Neuse River Basin. The existing structure at this site will not be altered. Division 5, 2612 N. Duke Street, Durham, NC 27704 Phone: (919) 560-6081 Fax: (919) 560-3371 2 Site 2 - Waters of US Construction at this site will have NO impacts to the unnamed intermittent tributary to Cabin Creek [NCDENR-DWQ Index No. 27-2-21-7, Best Usage Classification WS-IV NSW; HUC 03020201 ] (Figure 4) in the Neuse River Basin. The existing structure at this site will not be altered. Site 3 - Waters of US Construction at this site will have minor impacts to the unnamed intermittent tributary to Cabin Creek [NCDENR-DWQ Index No. 27-2-21-7, Best Usage Classification WS-IV NSW; HUC 03020201] (Figure 5) in the Neuse River Basin. The existing concrete structure at this site has separated joints on the outlet end (Photographs 1). This has resulted in a loss of material and a failed shoulder. NCDOT proposes to excavate these joints, reset them, and stabilize the structure with 5 feet of riprap along the outlet of the reset joints. This activity will not require dewatering of the site and will not result in additional fill.within this creek and adjacent lake. Riparian Buffer Impacts Site 1 - Buffers The construction at this site involves a road crossing of a stream that is subject to the Neuse Riparian Buffer Rule. The unnamed intermittent tributary to Cabin Creek at Site 1 is not depicted on the most recent version of the Northwest Durham (1973/1987) topographic quadrangle (Figure 1) but is depicted on the Soil Survey of Durham County (USDA-SCS, 1971) (Figure 2). Erosion and sediment control devices along the project are comprised of temporary rock silt checks, temporary silt basins, and temporary silt fence. The NCDOT proposes to install temporary erosion and sediment control devices in Zone 1 and Zone 2 of the riparian buffer. The temporary structures will be removed once the vegetation has been established and then seeded with a seed mixture of fescue and bahia grass. Please note that the placement of these structures are within the 60 right-of- way width and their associated impacts are included within the site total of 1,478 ft2 in Zone 1 and 959 tt'` in Zone 2 (totaling 24 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT. Site 2 - Buffers The construction at this site involves a road crossing of a stream that is subject to the Neuse Riparian Buffer Rule. The unnamed intermittent tributary to Cabin Creek at Site 1 is depicted on the most recent version of the Northwest Durham (1973/1987) topographic quadrangle (Figure 1) as well as on the Soil Survey of Durham County (USDA-SCS, 1971) (Figure 2). Erosion and sediment control devices along the project are comprised of temporary rock silt checks, temporary silt basins, and temporary silt fence. The NCDOT proposes to install temporary erosion and sediment control devices in Zone 1 and Zone 2 of the riparian buffer. The temporary structures will be removed once the vegetation has been established and then seeded with a seed mixture of fescue and bahia grass. Please note that the placement of these structures are within the 60 right-of-way width and their associated impacts are included within the site total of 1,177 ft' in Zone 1 and 830 ft' in Zone 2 (totaling 24 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT. It 3 Site _3 - Buffers The construction at this site involves a road crossing of a stream that is subject to the Neuse Riparian Buffer Rule. The unnamed intermittent tributary to Cabin Creek at Site 1 is depicted on the most recent version of the Northwest Durham (1973/1987) topographic quadrangle (Figure 1) as well as on the Soil Survey of Durham County (USDA-SCS, 1971) (Figure 2). Erosion and sediment control devices along the project are comprised of temporary rock silt checks, temporary silt basins, and temporary silt fence. The NCDOT proposes to install temporary erosion and sediment control devices in Zone 1 and Zone 2 of the riparian buffer. The temporary structures will be removed once the vegetation has been established and then seeded with a seed mixture of fescue and bahia grass. Please note that the placement of these structures are within the 60 right-of=way width and their associated impacts are included within the site total of 1,496 ft- in Zone 1 and 481 ftz in Zone 2 (totaling 24 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is EXEMPT. Waters of the U.S./Riparian Buffer 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: Construction of the project will result in only minimal impacts to waters of the United States. Impacts have been avoided and minimized to the maximum extent possible during the design process. Due to minimal impacts, compensatory mitigation for stream and riparian buffer impacts will not be provided for this project. 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 January 29, 2003, there are three federally protected species listed for Durham County. They include bald eagle (Haliaeeti.ts leucocephalus), smooth coneflower (Lchinacea lacvigata), and Michaux's sumac (Rhus n ichauxii). Lakeside Drive is not adjacent to open water suitable of supporting foraging habitat for the bald eagle. The roadway shoulders along Lakeside Drive are regularly maintained from the gravel to the woods line, eliminating the possibility for smooth coneflower or Michaux's sumac to exist in this area. Additionally, a review of the Natural Heritage Program database (last updated April 2005) revealed no occurrences of protected species within the project area. Therefore, based on lack of suitable habitat observed during the 03/15/05 site visit and the NHP database review, biological conclusions of No Effect have been rendered for each of these species. Historical Compliance This project has been screened by all pertinent parties to ensure historic compliance. Summary NCDOT proposes to upgrade and pave SR 1723 (Lakeside Drive) in Durham County. Rip rap armoring of reset joints and buffer impacts along the upgraded roadway are the only permanent impacts proposed for this project. Due to minimal impacts, compensatory mitigation for stream and riparian buffer impacts will not be provided for this project. Application is hereby made for a Department of the Army Section 404 Nationwide Permit (NWP) 14, NCDENR-DWQ Section 401 Water Quality Certification (WQC) No. 3404, and riparian buffer authorization for above-described activities. An automated payment procedure has been implemented between the NCDOT and NCDWQ. 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 of $200.00 directly to the appropriate NCDOT WBS element 5C.032052. A pre-construction notification is attached with this request. If you have any questions or need additional information, please contact Ms. Heather Montague at (919)560-6081. Sincerely, on G.

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. All wetlands and surface waters not affected by construction will be protected from unnecessary encroachment during construction. 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 or protected riparian buffers 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 9 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/ncwetIands/strmgide.litm1. 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. 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).
