Nance, RE NCDOT, Division 5 2612 N. Duke Street Durham, NC 27704 Dear Mr. Nance: Division Engineer You have our approval, in accordance with the conditions listed below, for the following impacts for the purpose of proposed pipe maintenance and improvement of a structure conveying Flatrock Creek on SR 1400 (Henry Ayscue Road) in Franklin County. Impact Stream Impacts - Concurrent Stream Impacts - Riparian Buffer Impacts (Square Feet) Locations Permanent Fill Temporary Dewatering- (Linear Feet) (Linear Feet) Site 1 38 75 4,271 (3,101 Zone 1 + 1,170 Zone 2) The project shall be constructed in accordance with your application dated received May 4, 2005. After reviewing your application, we have decided that the stream impacts and riparian buffer impacts described are covered by General Water Quality Certification Numbers 3494 and 3366. This certification corresponds to the Nationwide Permit 3 and the Nationwide Permit 33 issued by the Corps of Engineers. This approval is also valid for the Tar- Pamlico Buffer Rules (15A NCAC 2B .0259). 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 Completion Form" to notify DWQ when all work included in the 401 Certification has been completed. The responsible party shall complete the attached form and return it to the 401/Wetlands Unit of the Division of 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. N,,QQ??Q hCarolina ?/VQl!lC Transportation Permitting Unit 1650 Mail Service Center, Raleigh, North Carolina 27699-1650 2321 Crabtree Boulevard, Suite 250, Raleigh, North Carolina 27604 Phone: 919.733-1786 /FAX 919-733-6893/ Internet: htti):Hh2o.enr.state.nc.us/ncwetiands 3.) During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or protected riparian buffers. 4.) 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.) Pursuant to NCACI5A 2B.0259(6), sediment and erosion control devices shall not be placed in Zone 1 of any Tar-Pamlico River Buffer without prior approval by the NCDWQ. At this time, the NCDWQ has approved no sediment and erosion control devices in Zone 1, outside of the approved project impacts, anywhere on this project. Moreover, sediment and erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not compromised and that discharge is released as diffuse flow. 12.) 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. 13.) 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. 14.) If the above condition (#13) 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. 15.) No live or fresh concrete shall come into contact with waters of the state until the concrete has hardened 16.) 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. 17.) All work shall be performed during low or normal flow conditions. 18.) All fill slopes located in jurisdictional wetlands shall be placed at slopes no flatter than 3:1. 19.) A copy of this Water Quality Certification shall be posted on the construction site at all times. In addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained with the Division Engineer and the on-site project manager. 20.) For 75 linear feet of stream at Site 1 being impacted due to site dewatering activties, the site shall be graded to its preconstruction contours and revegetated with native vegetation. 21.) All protected riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the preconstruction contours and revegetated with native woody species upon completion of the project construction. A post-construction as-built with the restoration activities included shall be submitted to the DWQ no later than 60 days after the project is closed out by the Department of Transportation. If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must act within 60 days of the date that you receive this letter. To ask for a hearing, send a written petition that conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, P.O. Box 27447, Raleigh, N.C. 27611-7447.

EASLEY LYNDO TIPPETT GOVERNOR SECRETARY April 28, 2005 U.S. Army Corps of Engineers Raleigh Regulatory Field Office 6508 Falls of the Neuse Road, Suite 120 050755 Raleigh, NC 27609 Attention: Mr. Eric Alsmeyer, NCDOT Coordinator Subject: Proposed maintenance improvements to a structure conveying Flatrock Creek on SR 1400 (Henry Ayscue Road) in Franklin County. WBS element 5B.203511, STAT 10# 9800361. The North Carolina Department of Transportation (NCDOT) proposes to replace a pipe conveying Flatrock Creek on SR 1400 (Henry Ayscue Road) in Franklin County (Figures I - 3). Impacts to Waters of the United States The project crosses a perennial stream, Flatrock Creek, [NCDENR-DWQ Index No. 28-78-1- 12, Best Usage Classification B NSW; HUC 03020101] (Figure 3) in the Tar-Pamlico River Basin. The existing structure that conveys the creek is a 72-inch by 48-inch corrugated metal pipe arch that is 40 feet long with headwalls (see Photograph 1). This existing structure is rusted, undersized, and has resulted in a large blowhole at the outlet. Please note that the outlet of the proposed structure will be located inside the limits of this blowhole 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. The NCDOT proposes to replace the existing structure with an 81" x 59" corrugated metal pipe arch that is 60 feet long. 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 in the creek 20 feet upstream and 55 feet downstream of the existing pipe. These locations were chosen by the Bridge Maintenance Engineer as optimal to facilitate dewatering. 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 Division 5, 2612 N. Duke Street, Durham, NC 27704 Phone: (919) 560-6081 Fax: (919) 560-3371 2 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 pipe will be replaced. The sheet piling will be removed after construction. Permanent impacts at the site associated with the replacement of the structure involve a total of 20 feet of surface water fill and 18 feet of rip rap placed along the streambank to protect the structure. Temporary impacts will include the dewatering of 75 feet of stream (38 feet concurrent as well as 37 additional feet). Riparian Buffer Construction at this site involves a road crossing of a stream that is subject to the Tar-Pamlicd River Riparian Buffer Rules. Flatrock Creek at Site 1 is depicted on the most recent version of the Ingleside (USGS 1969) topographic quadrangle (Figure 1) as well as the Soil Survey of Franklin County (USDA-SCS, unpublished) (Figure 2). Construction impacts at this site total 3,101 ft' in Zone 1 and 1,170 ft'` in Zone 2 (totaling 75 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 ALLOWABLE. 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: Unavoidable impacts to 20 linear feet of stream associated with this project will be mitigated (at a 2:1 ratio) by providing 40 linear feet of warm water stream restoration equivalent in the Tar-Pamlico River Basin (Hydrologic Cataloging Unit 03020101). All compensatory mitigation requirements will be assimilated on a quarterly basis and provided to the Ecosystem Enhancement Program (EEP) for their acceptance with a copy provided to the USACE for verification and accounting purposes. 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 Franklin County. They include dwarf wedgemussel (Alasmidonta heterodon), Tar spinymussel (Elliptio steinstansana), and Michaux's sumac (Rhus michauxii). The roadway shoulders along Henry Ayscue Road are heavily maintained, eliminating the 3 possibility for Michaux's sumac to exist in this area. A mussel survey was conducted at this crossing by biologists with Alderman Environmental Services, Inc. on 04/05/05 with a finding of no habitat is present for mussel fauna and no protected mussels were observed during that survey. 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 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 structure with larger sized pipe. Permanent impacts at the site associated with the replacement of the structure involve a total of 20 feet of surface water fill and 18 feet of rip rap placed along the streambank to protect the structure. The work zone will be dewatered for approximately 2 weeks. Temporary impacts to the stream from this activity will result in the dewatering of 75 linear feet of stream. The sheet piling will be removed after construction. Riparian buffer impacts at Site 1 associated with this maintenance activity total 3,101 ft2 in Zone 1 and 1,170 ft2 in Zone 2 (totaling 75 linear feet of riparian buffer impacts). Based on the impacts to the riparian buffer at this site, this crossing is ALLOWABLE. 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 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 513.203511, STAT IO# 980361. 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.

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 Page 5 of 8 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/strmp,ide.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. Unavoidable impacts to 20 linear feet of stream associated with this project will be mitigate (at a 2.1 ratio) by providing 40 linear feet of wane water stream restoration equivalent in the Tar-Pamlico River Basin (Hydrologic Cataloging Unit 03020101), All compensatory mitigation requirements will be assimilated on a quarterly basis and provided to the Ecosystem Enhancement Program EEP) for their acceptance with a copy provided to the USACE for verification and accounting purposes. 2. 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): 40 ft Amount of buffer mitigation requested (square feet): N/A Amount of Riparian wetland mitigation requested (acres): N/A Amount of Non-riparian wetland mitigation requested (acres): N/A Amount of Coastal wetland mitigation requested (acres): N/A IX. Environmental Documentation (required by DWQ) Does the project involve an expenditure of public (federal/state/local) funds or the use of public (federal/state) land? Yes ® No ? Page 6 of 8 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 ? X. 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. 1. Will the project impact protected riparian buffers identified within 15A NCAC 2B .0233 (Neuse), 15A 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 I Zone* lmpact (square feet) Multiplier Required Mitigation 1 3,101 3 (2 for Catawba) 2 1,170 1.5 Total 4,271 * Zone 1 extends out 30 feet perpendicular from the top of the near bank of channel; Zone 2 extends an additional 20 feet from the edge of Zone I. 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 XI. 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 Page 7 of 8 the property. If percent impervious surface exceeds 20%, please provide calculations demonstrating total proposed impervious level. There is 0.04 acre existing impervious surface with the 0.2 acre project site. No additional impervious surface is proposed with this maintenance pipe replacement project Erosion and sediment control devices at this site are comprised of temporary silt fence and special stilling basin silt bag) XII. 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. XIII. 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 an after-the-fact permit application? Yes ? No XIV. 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: XV. Other Circumstances (Optional): It is the applicant's responsibility to submit the application sufficiently in advance of desired construction dates to allow processing time for these permits.
