The information included with this application has been developed in conjunction with the Town of Canton utilizing funds from the Hurricane Recovery Act of 2005 (Senate Bill 7). Currently, stormwater runoff from the west side of the Town of Canton drains into Mingus Cove Branch, which is piped under the western portion of the Blue Ridge Paper facility and is discharged through a dike into the Pigeon River. The piped system travels through sections of the wastewater treatment plant (WWTP) that are subject to flooding during high rainfall events. During flooding conditions, the WWTP may be inundated with flood waters leading to overflows and the degradation of water quality in the Pigeon River. The proposed project will replace portions of the stormwater infrastructure and re-route Mingus Cove Branch away from the WWTP. The approximately 293 feet of Mingus Cove Branch that is not currently piped will be dewatered from upstream flows with the relocation and upgrade of the stormwater conveyance system. This project involves the construction of approximately 3,525 linear feet of 54- and 60- inch diameter storm sewer to collect stormwater at an existing catch basin located between the Hardees restaurant and a used car lot along Highway 19/23. This storm sewer will convey, the stormwater eastward to the Pigeon River along the edge of Highway 19/23 (New Clyde Highway and Park Street).

PROJECT PURPOSE & DESCRIPTION The purpose of this project is to address stormwater runoff in the area of the Blue Ridge Paper Products site on the west side of the Pigeon River in Canton, North Carolina. Currently, stormwater runoff from the west side of the Town of Canton drains into Mingus Cove Branch which is piped under and through the western portion of the Blue Ridge Paper facility and is discharged through a dike into the Pigeon River. The piped system travels through sections of the wastewater treatment plant (WWTP) which is subject to flooding during high rainfall events. During flooding conditions, the WWTP is inundated with flood waters leading to overflows and degradation of water quality in the Pigeon River. This project involves the construction of approximately 3,525 LF of 54-inch and 60-inch diameter storm sewer collecting stormwater at an existing catch basin located between the Hardees restaurant and a used car lot along Highway 19/23 and conveying stormwater eastward to the Pigeon River along the edge of Highway 19/23 (New Clyde Highway and Park Street). New catch basins are proposed along this route to address surface drainage issues along the Highway 19/23 corridor. The drainage area of the Mingus Cove Branch is approximately 320 acres. Of this, approximately 21 percent of the area is impervious. The work described in this project is urgent and compelling work for the Town of Canton utilizing funds appropriated from the Hurricane Recovery Act of 2005 (Senate Bill 7). The Town of Canton is the sponsor and the responsible party for this work. All work on this project will be supervised by trained personnel from McGill Associates, P.A. 2. SITE DESCRIPTION The construction project site consists of NCDOT road right-of-way with minimal sections across private property. The proposed system begins at an existing catch basin which is part of the existing piped system of Mingus Cove Branch. The proposed system will redirect the piped system toward Highway 19/23, then along the roadway to the Pigeon River. The potential impacts to the Mingus Cove Branch segments are located upstream of the Blue Ridge Paper site. These four open channel segments have a total measured length of 293 LF, with this length being field measured and verified. The proposed project would remove base flow from these segments of stream, resulting in dewatering of these stream segments. These stream segments currently experience high flows from the upstream stormwater conveyance system during storm events. These segments are currently networked with an outdated pipe and culvert system consisting of varying pipe sizes and pipe material. The stream segments exhibit signs of severe erosion and unstable banks. Of note, the open sections of Mingus Cove Branch are piped up-gradient and down-gradient of this area. See Drawing COE-1 in Appendix B for an overview of the proposed project. Storm Drainage - West Canton Improvements November 25, 2008 • Haywood County McGill Associates, P.A. 3. DESIGN CONSIDERATIONS Several options were considered for this project. Two of the options involved improvements to the existing stormwater conveyance system on the Blue Ridge Paper site property. Option 1 • involved replacing the existing stormwater conveyance pipe system with a larger diameter conveyance system, while maintaining the existing route. This option was not selected due to multiple utility conflicts associated with the larger stormwater pipes, close proximity to the wastewater treatment plant basins, and disruption of operations at Blue Ridge Paper during • construction activities. Also, this option did not result in any improvement to potential water quality effects as the discharge into the Pigeon River would have to go through the dike creating a source for the river to back up into the WWTP site. Option 2 involved the re-routing and upgrading of the existing stormwater conveyance system on • the Blue Ridge Paper site. This option would move the existing stormwater conveyance system to a more desirable location away from the wastewater treatment plant, but would require blasting of bedrock to install the proposed line. Option 2 was not selected because a portion of the blasting would occur in close proximity to the wastewater treatment plant basins (less than 50 • feet from the basin) and would disrupt operations at Blue Ridge Paper during construction activities. Also, this option did not result in any improvement to potential water quality effects as the discharge into the Pigeon River would have to go through the dike creating a source for the river to back up into the WWTP site. The selected option, Option 3, involves intercepting drainage upstream of Blue Ridge Paper and installing a new stormwater conveyance system along the Highway 19/23 corridor. This would remove excess drainage from the existing system which is overburdened during storm events, not • involve construction in close proximity to the wastewater treatment basins, and address additional known existing drainage concerns along Highway 19/23. 4. PROPOSED PLAN Option 3 will include the re-routing of the existing stormwater conveyance line upstream of the Blue Ridge Paper site. This project will consist of the installation of 3,525 LF of 54-inch and 60- inch diameter storm drainage pipe beginning at an existing catch basin near Hardees restaurant • on Highway 19/23 (New Clyde Highway) and conveying the stormwater to the Hwy 19/23 right- of-way, then eastward to the Pigeon River south of the West Park Street bridge. The proposed conveyance system will include the addition of catch basins in order to effectively collect surface runoff from Highway 19/23. This will help alleviate existing flooding conditions around the . local Post Office and improve drainage along Highway 19/23 corridor. The proposed system will also divert stormwater runoff away from the existing stormwater conveyance system piped under the Blue Ridge Paper site, minimizing the potential future impact of water quality degradation from the wastewater treatment during significant storm events. Storm Drainage - West Canton Improvements November 25, 2008 • Haywood County McGill Associates, P.A. • 5. DIRECT AND INDIRECT IMPACTS By implementing this project, the following impacts are anticipated: 1. No direct work is being proposed within waters of the state. 2. Diversion of stormwater runoff away from the Blue Ridge Paper site resulting in minimizing flooding in the area of the wastewater treatment plant. This will lessen potential degradation of water quality in the Pigeon River due to flooding of the • wastewater treatment plant. 3. Base flow generated within the drainage basin served by this project would be diverted from four open channel segments with a total length of 293 LF. This would result in • dewatering of these stream segments. See potentially impacted stream segments on Drawing COE-02. Note that the open channel sections of Mingus Cove Branch are piped 0 up-gradient and down-gradient of the Area of Impact. Refer to photos in Appendix A of the potentially impacted stream segments 6. MITIGATION • Mitigation is not proposed for this project. 6. REGULATORY REQUIREMENTS 401 WATER QUALITY CERTIFICATION (Requirements based on typical Certification conditions) - The following mandatory conditions apply to all repair sites: • 1. Erosion and Sediment Control Practices 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. 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 • Planning and Design Manual. The devices shall be maintained on all construction sites, borrow sites, and waste pile (spoils) 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. -- 4 -- Storm Drainage - West Canton Improvements November 25, 2008 • Haywood County McGill Associates, P.A. • d. The reclamation measures and implementation must comply with the requirements of the Sedimentation Pollution Control Act. 2. No Waste, Spoil, Solids, or Fill of Any Kind - 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 Pre-Construction Notification. 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. No Sediment & Erosion Control Measures within Wetlands or Waters - Sediment and erosion control measures shall not be placed in wetlands or water 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 (6) months. 4. Certificate of Completion - Upon completion of all work approved within the 401 Water • Quality Certification or applicable Buffer Rules and any subsequent modifications, the applicant is required to return a certificate of completion to the 401/Wetlands Unit, North Carolina Division of Water Quality, 1650 Mail Service Center, Raleigh, NC 27699- 1650. 5. Sediment and erosion control measures must be implemented prior to construction and maintained on the sites to minimize sediment in downstream areas. Seeding for a temporary cover of wheat, millet, or similar annual grain or permanent herbaceous cover should occur on all bare soil within five (5) days of ground disturbing activities to • provide long-term erosion control. The projects should be accomplished in stages instead of leaving large tracts exposed to further storm events. Erosion control matting Flexible Growth Media should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas, unless authorized under Division of Land Resources Erosion and Sediment Control approval. Matting should be secured in place with staples, stakes, or wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian zones. • 6. Stabilization measures should only be applied on or near existing erosion sites, leaving other stable stream bank areas in a natural condition. Grading and backfilling should be minimized and tree and shrub growth should be retained where possible to ensure long- term availability of stream bank cover for aquatic life and wildlife. Backfill materials should be obtained from upland sites except in cases where excess streambed materials are available. Berms are not permitted because they block the floodplain, constrict and accelerate flood flows, and often fail or impede drainage during large flood events. 7. Repairs to eroded banks should be conducted in a dry work area where possible. • Sandbags or other clean diversion structures should be used where possible to minimize excavation in flowing water. -- 5 -- Storm Drainage - West Canton Improvements November 25, 2008 . Haywood County McGill Associates, P.A. • 8. Heavy equipment should be operated from the bank whenever possible. All mechanized equipment operated near surface waters should be inspected and maintained regularly to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids or other toxic materials. Equipment used in stream channels must be clean, new or low-hour equipment. 9. The Permittee will provide on-site supervision of stability work. 10. Diffuse Flow - All constructed storm water conveyance outlets shall be directed and maintained as diffuse flow at non-erosive velocities through the protected riparian zones such that it will not re-concentrate before discharging into a stream. 11. Water Quality Certification Notification - The Permittee must provide a copy of this • issued Water Quality Certification and attached cover letter to each property owner where the approved work will be performed. Finally, pending receipt of a final 404 Permit and 401 Certification, copies of these issued i documents and the associated conditions and comments provided by commenting agencies (when available) will be included in all final contractor packages that will be used for construction of the repairs. All regulatory requirements and the measures outlined in this document will be fully discussed with the chosen contractor and the inspectors for McGill • Associates before any construction begins. During actual construction, inspectors will direct contractors to observe and apply good construction practices and the requirements described in this document.

Describe the existing conditions on the site and general land use in the vicinity of the project at the time of this application: The site involves less than 300 LF of open stream which serves as drainage to over 320 acres of drainage area . The drainage area includes rural (mountainous) property as well as commercial properties bordering US Highway 19/23. The affected stream sections convey base flow and stormwater runoff from piped sections of stream to another piped section under portions of the Blue Ridge Paper site. • 10. Describe the overall project in detail, including the type of equipment to be used: The Project will consist installation of 3,525 LF of 54 and 60 inch diameter storm drain be innin at an existing catch basin near Hardees restaurant on Highway 19/23 (New Clyde Highway) . and conveying stormwater to the Hwy 19/23 right-of-way, then eastward to the Pigeon River south of the West Park Street bridge. The proposed system will also collect surface runoff from Highway 19/23. This will alleviate flooding conditions around the Post Office and improve drainage along Highway 19/23. The proposed system will divert base flow and • stormwater runoff away from the piped system under Blue Ridge Paper. 11. Explain the purpose of the proposed work: The purpose of the proposed work is to alleviate flooding in and around the Blue Ridge Paper site. The existing piped system conveys base flow and runoff through the Blue Ridge Paper site and more specifically through the Wastewater Treatment Plant area. Durin heavy rain events there is localized flooding in this area thus creating a potential for water quality degradation. IV.

Please note that this section only applies to waters that have specifically been determined to be isolated by the USACE. 8. 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 Page 9 of 13 Describe the method of construction (e.g., dam/embankment, excavation, installation of • draw-down valve or spillway, etc.): Proposed use or purpose of pond (e.g., livestock watering, irrigation, aesthetic, trout pond, local stormwater requirement, etc.): Current land use in the vicinity of the pond: • Size of watershed draining to pond: Expected pond surface area: 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. Potential piping improvements through Blue Ridge Paper site were determined to be un-implementable due to interruption of site activities, construction restraints of placing large pipe through the wastewater treatment plant area, potential for blasting in very close proximity to the wastewater treatment plant and high • construction cost. Also, this did not result in any improvement to potential water quality effects as the discharge into the Pigeon River would have to o through the dike creating a source for the river to back up into the WWTP site. • 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 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/stringide.html.

Does the project involve an expenditure of ublic (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 N 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 ? 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 11 of 13 . 1.
