Ross Jr., Secretary North Carolina Department of Environment and Natural Resources Alan W. Klimek, P.E. Director Division of Water Quality July 6, 2005 Rockingham County DWQ Project No. 05-1087 NC 87 APPROVAL of 401 Water Quality Certification Mr. J.M. Mills, P.E. Division Engineer, Division 7 North Carolina Department of Transportation 1584 Yanceyville Street Greensboro, North Carolina, 27415 Dear Mr. Mills: You have our approval, in accordance with the attached conditions and those listed below, to incur the following impacts to an unnamed tributary to Giles Creek in order to widen and improve NC 87 in Rockingham County. • 16 linear feet of piping impacts; • up to 20 linear feet of rip rap for bank stabilization; and • Temporary dewatering impacts of approximately 50 linear feet. The project shall be constructed in accordance with your application dated June 13, 2005 (received June 17, 2005). After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Nos. 3495, 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 13, 14 and 33. 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 Division of Water Quality (Division) and submit a new application. If the property is sold, the new owner must be given a copy of this approval letter and certifications, 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 if 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 and any additional conditions listed below. Erosion and sediment control practices must be in full compliance with all specifications governing the proper design, installation and operation and maintenance of such Best Management Practices in order to protect surface waters standards: a. The erosion and sediment control measures for the project must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Sediment and Erosion Control Planning and Design Manual.

Mills, P.E. July 6, 2005 DWQ# 05-1087 Page 2 b. The design, installation, operation, and maintenance of the sediment and erosion control measures must be such that they equal, or exceed, the requirements specified in the most recent version of the North Carolina Sediment and Erosion Control Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased borrow pits associated with the project. c. For borrow pit sites, the erosion and sediment control measures must be designed, installed, operated, and maintained in accordance with the most recent version of the North Carolina Surface Mining Manual. d. The reclamation measures and implementation must comply with the reclamation in accordance with the requirements of the Sedimentation Pollution Control Act. 2. No waste, spoil, solids, or fill of any kind shall occur in wetlands, waters, or riparian areas beyond the footprint of the impacts depicted in the Preconstruction Notice Application. All construction activities, including the design, installation, operation, and maintenance of sediment and erosion control Best Management Practices, shall be performed so that no violations of state water quality standards, statutes, or rules occur. 3. Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum extent practicable. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored within six months of the completion of the project. 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. Stormwater should be directed to vegetated buffer areas, grass lined ditches or other means appropriate to the site for the purpose of pre-treating stormwater runoff, and must not be routed directly into streams. Mowing of existing vegetated buffers is strongly discouraged, so that they may be utilized for stormwater sheet flow. 6. Where practicable, culverts that are less than 48-inch in diameter should be buried to a depth equal to or greater than 20% of their size to allow for aquatic life passage. Culverts that are 48-inch in diameter or larger should be buried at least 12 inches below the stream bottom to allow natural stream bottom material to become established in the culvert following installation and to provide aquatic life passage during periods of low flow. These measurements must be based on natural thalweg depths. This may require increasing the size of the culvert to meet flow conveyance requirements. If any of the existing pipes are perched, they shall be removed and replaced, and re-installed correctly, unless demonstrated that this is topographically unfeasible. All waters must flow through without freefalling or damming on either end of the culverts during low flow conditions, to maintain aquatic life and/or fish passage. 7. 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. 8. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 9. Use of rip-rap for bank stabilization is to be minimized; rather, native vegetation is to be planted when practical. If rip-rap is necessary, it must be limited to the stream bank below the high water mark, and vegetation must be used for stabilization above high water. Any rip-rap used must not interfere with aquatic life passage during low flow conditions. 10. If concrete is used, work must be accomplished so the wet concrete does not contact the stream water. This will lessen the chance of altering the stream's water chemistry and causing a fish kill. 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. 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. 13. 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. 14. Temporary dewatering sites must be restored to preexisting conditions unless more natural geomorphic conditions can be provided. Mr. J.M. Mills, P.E. July 6, 2005 DWQ# 05-1087 Page 3 15. All work shall be performed during low flow conditions. 16. 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.

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.): Not Applicable Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Not Applicable Size of watershed draining to pond: N/A Expected pond surface area: N/A VII. 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. Pine replacement activities are necessarv to increase travel lane and shoulder width to current construction standards. Impacts will be minimized by strict enforcement of Best Management Practices for the protection of wetland and surface waters, restrictions against the staging of equipment in or adjacent to waters of the US, and coordination (including a pre-construction meeting) with the Division Environmental Officer. 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. Page 5 of 8 USACE - In accordance with the Final Notice of Issuance and Modification of Nationwide Permits, published in the Federal Register on March 9, 2000, 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 NCWRP 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.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. A finding of insignificant impact is anticipated; therefore, a mitigation plan is not provided. Cumulative impacts are less than 150 feet. The maximum amount of impact to a singe stream is 16 linear feet. No Outstanding Resource Waters, federally protected species or their habitats, or essential fishery habitats occur in the project area. The project is not located in a High Quality Water. 2. Mitigation may also be made by payment into the North Carolina Wetlands Restoration Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at (919) 733-5208 to determine availability and to request written approval of mitigation prior to submittal of a PCN. For additional information regarding the application process for the NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wm/index.htm.

COU GREENSBORO MONTICELLO June 14, 2005 Construction Sequence and Erosion Control Plan for Pipe Extension Rockingham County - NC 87 1. Install a rock silt dam (underlain with filter fabric) downstream of work area to prevent incidental sediment loss. 2. Install ABC aggregate or a less intrusive dewatering device to allow dewatering of work area. 3. If necessary install pumps to divert flow around work area. 4. Excavate to sufficient depth to allow 20% of pipe diameter burial of pipe replacement, place bass stone and install 8' of new pipe on inlet and outlet of existing 40' x 24" RCP. 5. A 10' X 15' siltbag will be used to remove any excess water in work area. 6. Backfill new pipe and place rip rap for bank stabilization, if necessary. 7. Silt dams removed from downstream end then upstream end with natural stream contour restoration. 8. Notify landscape department for final seeding. 9. Silt fences to be placed, as site conditions require. 10. A less obtrusive method than a pump around system may be utilized if site conditions allow. 11. Site conditions and weather may alter these plans. NC 87 - INLET PIPE
