Per your request, this office will provide information concerning the events leading to the violations and corrective measures taken and planned. This office acknowledges it performed work prior to receiving appropriate permit modifications and failed to follow all BMP's for the work performed on the Reeves Cove Road project in Haywood County. This office acknowledges it did violate site stabilization requirements on another project in Haywood County. The following is the sequence of events on the Reeves Cove Road project: ? February 10, 2006 - NCDOT applied for a Nationwide Permit 14 and 401 WQC. ? March 1, 2006 - NCDOT received a letter from DWQ dated February 24, 2006 asking for additional information regarding the channel relocation. ? August 31, 2006 - NCDOT applied for a permit modification, which included the channel relocation plans. ? September 6, 2006 - NCDOT received the US Army Corps of Engineers NWP 14. ? September 15, 2006 - NCDOT received the 401 certification from DWQ. Fourteenth Division ,Office, 251W;bstet RoA Sylvan; NoriH .C4,40w xC8 43 , ''Telephone: 828-586-2.14t ?Y,",doh:dot.state.itc-uV SR 1511 NOV Page 2 December 18, 2006 ? September 18, 2006 - Construction began on the project. ? October 16, 2006 - The channel relocation was completed. Upon completion, NCDOT received a request to restore access to a property owner's barn. Access to the barn existed prior to the channel relocation. Restoring access required adding twenty feet of pipe in Crabtree Creek. Since this pipe was not included in the permit, NCDOT determined a permit modification was necessary. ? October 26, 2006 - NCDOT Environmental Officer and project personnel met with Mike Parker to review the proposed permit modification. Mr. Parker indicated a permit modification was feasible for the pipe installation. ? October 31, 2006 - NCDOT applied for a permit modification for an additional twenty linear feet of stream impact. ? November 6, 2006 - Mr. Parker conducted a site visit. He discovered NCDOT was just completing the culvert installation. He observed the creek below the pipe installation was muddy. This activity was completed prior to the issuance of the modified 401 WQC. ? November 22, 2006 - NCDOT received the Notice of Violation from DWQ dated November 20, 2006. ? December 7, 2006 - NCDOT received the modified 401 WQC dated December 1, 2006, which included the additional 20 linear feet of stream impact associated with the new access road. Impacts to Streams Without Proper 401 WQC Coverage As indicated in the above timeline, NCDOT did cause impacts to Crabtree Creek on Reeves Cove Road prior to receiving the permit modification. In investigating why our personnel directed this work prior to receiving the permit modification, we learned that project personnel did not clearly understand the permit modification must be received prior to performing this work. Although it was clearly understood by Division 14 managers and environmental staff that verbal approval for permit modifications are only issued in emergency situations, project personnel incorrectly believed the verbal approval was given for the permit modification at the meeting on October 26, 2006. This office issued the attached memorandum to Division 14 to project engineers stating that verbal approvals issued by any agency will be documented and a copy of this documentation will be on the project. Division 14 is scheduling environmental training this winter and this topic will be heavily emphasized at that meeting. Failing to Follow BNIP's During Culvert Installation Interviews with project personnel on the Reeves Cove Road project indicate not all BMP's were followed. The culvert was installed by excavating the new channel for the culvert in the dry from the outlet end to the inlet end, placing the new culvert into the channel and backfilling the culvert, then directing the creek's flow into the new culvert. It was determined all BMP's were not followed by failing to keep all flow of Crabtree Creek in the existing channel by diking the inlet side on the new channel for the pipe. As a result a slight portion of the flow did enter the new channel prior to being stabilized with the new culvert. As part of the planned environmental training mentioned above, BMP's for installing culverts in streams will be heavily emphasized. SR 1511 NOV Page 3 December 18, 2006 Proper Site Stabilization A review of records on the Reeves Cove Road project indicates NCDOT did meet site stabilization goals and requirements on this project. However, this office has determined that site stabilization requirements were not met on at least one other project in Division 14 this past year. In investigating this problem, Division 14 managers have identified needed improvements in meeting its obligations to stabilizing construction sites. Division 14 has begun a process that will identify projects with problems in meeting fifteen-day ground cover requirements and notify decision-makers of these projects. This process will enable persons with authority to take corrective actions prior to projects becoming non-compliant. This new process will be finalized in February 2007 prior to the start of the 2007 construction season. In addition to the measures describe above, Division 14 is also implementing the following measures to enhance its environmental program: ? Preconstruction conferences will be held on all projects with permits or more than one half acre of ground disturbance beginning in April 2007. A project checklist is being developed to guide project engineers and field personnel regarding content of the conference. ? On all projects requiring preconstruction conferences as described above, Division 14 will name an environmental agent and a project engineer. Roles and responsibilities of these persons will be defined prior to the start of construction. ? The environmental training being planned within Division 14 will include guidance for project inspectors on contract construction projects regarding control of contractors operations. In closing, this office would like to reassure you that Division 14's commitment to delivering projects while protecting and enhancing the natural environment is strong. It is our expectation that we fully comply with all environmental laws and polices and work within the parameters of all permits and special conditions. This office believes the measures planned will achieve these objectives. If you would like any additional information or have any suggestions for improvement, we would appreciate your input. If any of this information needs further explanation, do not hesitate to contact us. Sincerely, ?f Joel Setzer, Division Engineer Mark S.

NC Department of Transportation 253 Webster Road Sylva, NC 28779 Mark Davis, Environmental Officer NC Department of Transportation 253 Webster Road Sylva, NC 28779 Dear Sirs: NOV 2 2 2006 401 Certification Condition Items, Stabilization Efforts, Potential Water Quality Impacts and Standards Violations NC Department of Transportation, Division 14 Based on recent site visits and file review, it has come to the attention of Division of Water Quality that a number of issues encountered in the Department of Transportation's Division 14, warrant immediate attention. More specifically, concerns encountered in Division 14 focus on the following issues: 1. Impacts to streams (culvert installation) without the proper 401 WQC coverage; and 2. Following Best Management Practices (BMPs) during culvert installation and possible violation of Water Quality Standards; and 3. Proper site stabilization (timing of grubbing, and providing a ground cover, in particular). Item 1.: On November 6, 2006, Mr. Mike Parker of the Division of Water Quality's (DWQ) Asheville Regional Office conducted a site visit of Reeves Cove Road, NCSR 1511, in Haywood County. During the site visit, Mr. Parker took photographs and made observations of ongoing activities at the project. The project included the relocation of an unnamed tributary to Crabtree Creek, Class C waters in the French Broad River Basin. 011C N thCarolin Aawra!!y Subject: Notice of Violation N. C. Division of Water Quality 2090 US Highway 70 Phone: (828) 296-4500 Asheville Regional Office Swannanoa, NC 28778 Fax: (828) 299-7043 An Equal Opportunity/Affirmative Action Employer - 50% Recycled/10% Post Consumer Paper Mr. J. B. Setzer, P.E. Mr. Mark Davis November 20, 2006 Page Two NC Department of Transportation stream relocation activities at the site had eliminated access to the property located at 285 Reeves Cove Road. The property owner requested access be restored, thus requiring an additional impact of 20 linear feet to the unnamed tributary to Crabtree Creek, upstream of the relocated segment, for a culvert to allow the desired access. A file review revealed that a request for a modification to the 401 Water Quality Certification (WQC) for the additional 20 feet of impact was submitted by the NC Department of Transportation. Division of Water Quality staff received this request on November 6, 2006. As of the November 6, 2006, Division of Water Quality site visit, a review of 401 Certification Application for the additional 20 linear feet of stream impact had not been completed, and the modification had not been issued to NC Department of Transportation. On November 6, 2006, Division of Water Quality staff observed that work on the installation of a culvert had begun at the site prior to the issuance of any modification to the 401 Water Quality Certification for the activity. Item 2: In addition, installation of the culvert was not being conducted in the dry, as outlined in NC DOT's Best Management Practices for Construction and Maintenance Activities and listed as Condition No. 14 in the original 401 Water Quality Certification dated September 15, 2006. As a result of this activity the downstream waters were noted to be very muddy and probably resulted in violation of Water Quality Standards for turbidity, however, no stream samples were collected. When construction activities are performed in, or near streams, the watercourse must be managed to prevent adverse impacts to jurisdictional waters. Waters draining from or impacted by the work area must be kept from mixing with downstream waters. In order to achieve this goal, work in, or near streams must meet the following three conditions: 1. The work area must be dewatered so that work can be accomplished "in the dry". 2. Equipment and materials must be kept from entering the stream channel. 3. Appropriate erosion and sedimentation control measures must be maintained and best management practices employed. Item 3: ' Another issue that merits immediate attention is proper erosion and sedimentation control stabilization efforts. On a number of occasions, the window of time by which groundcover has not been provided at construction sites is beyond the required 15 day time period. This procedure is unacceptable, and is a violation of general conditions of the 401 Water Quality Certification as well the Department of Transportation's Best Management Practices for Construction and Maintenance Activities. If equipment is faulty or inoperable such that a groundcover cannot be provided within the required time period, replacement equipment or other means must be secured so that work on the site may remain in compliance with regulations. Mr. J. B. Setzer, P.E. Mr. Mark Davis November 20, 2006 Page Three As a result of the site inspection and file review of Reeves Cove Road, NCSR 1511, in Haywood County, the following violations detailed below, are noted: 1. 401 WQC Conditions 2. Removal of Best Usage Item 1: 401 WQC Conditions The impacts beyond those that were set forth in the 401 Water Quality Certification represents a violation of the Certification. Mr. Mark Davis, Division 14 Environmental Officer, NC Department of Transportation, 253 Webster Road, Sylva, North Carolina 28779, submitted a Pre-Construction Notification (PCN) on September 6, 2006. The impacts were requested under U.S. Army Corps of Engineers Nationwide Permit 14, and the corresponding General Water Quality Certification 3404. DWQ issued an approval letter for the impacts on September 15, 2006. The approval letter specifies that the activities must follow the conditions listed in the General Water Quality Certification, as well as additional conditions listed in the letter. Water Quality Certification No. 060254, Condition 2, 14, and 18 state(s) the following: Condition 2. "There shall be no excavation, from or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact form road constriction activities." Condition 14. "All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the most current version of NCDOT Construction and Maintenance manual such as sandbags, rock berms, cofferdams and other diversion strictures should be used to prevent excavation in flowing water." Condition 18. "The pennittee and its authorized agents shall conduct its activities in a manner consistent with State water quality standards (including the requirements resulting from compliance with 303(d) of the Clean Water Act) and any other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met (including failure to sustain a designated achieved use) or that State or Federal law if being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification. Item 2: Removal of Best Usage Unauthorized installation of a culvert represents a violation with 15A NCAC 02B .0211 (2), which states: "The waters shall be suitable for aquatic life propagation and maintenance of biological integrity, wildlife, secondary recreation, and agriculture; sources of water pollution which preclude any of these uses on either a short-term or long- term basis shall be considered to be violating a water quality standard." Mr. J. B. Setzer, P.E. Mr. Mark Davis November 20, 2006 Page Four Requested Response This Office requests that you respond to this letter in writing within 30 days of receipt of this Notice. Your response should be sent to both this office at the letterhead address and to the attention of Mr. Danny Smith at the Wetlands and Stormwater Branch, NPS Assistance and Compliance Oversight Unit, 1617 Mail Service Center, Raleigh, NC 27699-1617. Your response should address the following items: Please clearly explain why appropriate 401 Water Quality Certification modifications were not secured before work began on the project. Please detail the events that resulted in non-compliance with the above- mentioned 401 WQC conditions. Please explain how you propose to prevent these problems (401 conditions compliance, working in the dry, securing 401 WQC modifications, and stabilization activities) from reoccurring on fixture projects. Thank you for your attention to this matter. Please note that the Division of Water Quality routinely issues Notices of Violation for impacts similar to those listed above. Your above-mentioned response will be considered in further regulatory decisions regarding these matters. Concerns with impacts to streams during improper culvert installation and other constriction related activities are not limited to the Reeves Cove project. This type of violation has been observed in other settings, and warrants further scrutiny and immediate action by the NC Department of Transportation beyond Division 14. Finally, DWQ wishes to better understand the nature and types of issues and complaints the Department of Transportation typically encounters with construction projects, and how communications between the Division of Water Quality and the Department of Transportation can be enhanced in the future. Also, please do not hesitate to provide any additional information in your written response that you feel merits consideration by the Division of Water Quality. Should you have any questions regarding these matters, please contact Mr. Mike Parker at (828) 296-4500.

The project should be constructed in accordance with your original application dated February 10, 2006 (received February 17, 2006), revised application dated August 31, 2006 (received September 6, 2006) and another revised application dated October 31, 2006 (received November 6, 2006), including the environmental commitments made in the application letters. After reviewing your applications, we have decided that this till is covered by General Water Quality Certification No. 3404, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you must 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 Water Quality Certification will expire with the accompanying 404 Permit issued by the US Army Corps of Engineers. 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 in writing 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 oC No hCaro ina Nature !y North Carolina Division of Water Quality 2090 U.S. Highway 70 Swannanoa, NC 28778 Internet: www.ncwaterquality.org Phone (828) 2964500 Customer Service FAX (828) 299-7043 1-877-623-6748 An Equal Opportunity/Affirmative Action Employer Mr. J. B. Setzer, Y.E. December 1, 2006 Page Two 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 21-1.0506 (h) (6) and (7). For this approval to be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. 1. 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. 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. There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 3. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored upon completion of the project. 4. Placement of culverts and other structures in waters, streams and wetlands, shall 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, streambeds or banks, adjacent to, or upstream and down stream of the above structures. The applicant is required to provide evidence that equilibrium is being maintained, if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on how to proceed and to determine whether or not a permit modification will be required. 5. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream aquatic resources. Temporary cover (wheat, millet or similar annual grain) or permanent herbaceous cover should be planted on all bare soil within fifteen (15) days of ground disturbing activities to provide long-term erosion control. Erosion control mating should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. 6. Compensatory mitigation for impacts to 210 linear feet of streams at a replacement ratio of 1:1 is required. We understand, based on the 401 Certification Application, that you have chosen to perform compensatory mitigation for impacts to streams through the North Carolina Ecosystem Enhancement Program (EEP). 7. All channel relocations will be constructed in a dry work area and stabilized before stream flows are diverted. Channel relocations will be completed and stabilized, and must be approved on site by DWQ staff, prior to diverting water into the new channel. Whenever possible, channel relocations shall be allowed to stabilize for an entire growing season. Vegetation used for bank stabilization shall be limited to native woody species, and should include establishment of a 30-foot wide wooded and an adjacent 20-foot wide vegetated buffer on both sides of the relocated channel to the maximum extent practicable. A transitional phase incorporating coir fiber and seedling establishment is allowable. Also, riprap may be allowed if it is necessary to maintain the physical integrity of the stream, but the applicant must provide written justification and any calculations used to determine the extent of riprap coverage area. 4tr Mr. J. B. Setzer, P.E. December 1, 2006 Page Three 8. The dimension, pattern and profile of the stream, above and below the crossing, should not be modified. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 9. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 10. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and vegetation should be used for stabilization above the high water elevation. Riprap should not be place in the active thalweg channel or placed in the streambed in such a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. 11. Heavy equipment should be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 12. All mechanized equipment operated near surface waters must be regularly inspected daily and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 13. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 14. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures should be used to prevent excavation in flowing water. 15. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 16. If concrete is used during construction (e.g., headwalls), a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pIl and possible aquatic life and fish kills. 17. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this certification. 18. The permittec and its authorized agents shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met (including failure to sustain a designated achieved use) or that State of Federal law if being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification. 19. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with the bank stabilization work. 20. 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. 21. Upon completion of the project, the NCDOT Division Engineer, shall complete and return the enclosed "Certificate of Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree Blvd., Suite 250, Raleigh, North Carolina 27604. 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, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714.

The original permit application dated February 10, 2006 included three pipe extensions totaling 54 linear feet of impact to an unnamed tributary of Crabtree Creek (DWQ Class: Q. NCDOT submitted a permit modification letter dated August 31, 2006 for a 210-foot channel change, which was inadvertently left off of the original permit application. During construction of the channel change an old access road to a barn was removed due to the location of the new stream channel (Sta. 17+40 and 19+50). In order to provide access back to the barn, NCDOT is requesting to install an additional 20 linear feet of CMP in the unnamed tributary to Crabtree Creek near Station 19+60 (Site 5). This will increase the total stream impacts due to culvert installation from 54 linear feet to 74 linear feet. I have enclosed a revised impact table to the PCN application, topographical map and a new cross section of the culvert at Site 5. Permits Requested NCDOT is hereby requesting authorization under NWP 14 and Section 404 of the Clean Water Act to proceed with this project. By copy of this letter, I am asking Mr. David McHenry of the North Carolina Wildlife Resources Commission to comment directly to the Corps concerning the 404 Nationwide Permit Modification Request. SR 151 1 Reeves Cove Road Page 2 October 31, 2006 Also by copy of this letter, I am requesting authorization to proceed under Section 401 of the Clean Water Act from the Division of Water Quality.

Director Division of Water Quality September 15, 2006 Haywood County DWQ Project No. 060254 NCSR 1511 (Reeves Cove Road) APPROVAL of 401 Water Quality Certification with Additional Conditions Mr. J. B. Setzer, P. E. Division Engineer N C Department of Transportation 253 Webster Road Sylva, North Carolina 28779 Dear Mr. Setzer: You have our approval, in accordance with the attached conditions and those listed below, to impact 264 linear feet in two (2) unnamed tributaries to Crabtree Creek (54 linear feet of new pipe and 210 linear feet of stream relocation), in order to make improvements to NCSR 1511 (Reeves Cove Road) in Haywood County. The project should be constructed in accordance with your original application dated February 10, 2006 (received February 17, 2006) and revised application dated August 31, 2006 (received September 6, 2006), including the environmental commitments made in the application letter. After reviewing your application, we have decided that this till is covered by General Water Quality Certification No. 3404, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Number 14. In addition, you must 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 Water Quality Certification will expire with the accompanying 404 Permit issued by the US Army Corps of Engineers. 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 in writing 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 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 be valid, you must follow the conditions listed in the attached certification and any additional conditions listed below. 1. 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. 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 anti 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.

B. Setzer, P.E. September 15, 2006 Page Two 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. There shall be no excavation from or waste disposal into, jurisdictional wetlands or waters associated with this permit without appropriate modification. Should waste or borrow sites be located in wetlands or streams, compensatory mitigation will be required since that is a direct impact from road construction activities. 3. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they shall be removed and the natural grade restored upon completion of the project. 4. Placement of culverts and other structures in waters, streams and wetlands, shall 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, streambeds or banks, adjacent to, or upstream and down stream of the above structures. The applicant is required to provide evidence that equilibrium is being maintained, if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting features encountered during construction, please contact the NC DWQ for guidance on how to proceed and to determine whether or not a permit modification will be required. 5. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream aquatic resources. Temporary cover (wheat, millet or similar annual grain) or permanent herbaceous cover should be planted on all bare soil within fifteen (15) days of ground disturbing activities to provide long-term erosion control. Erosion control mating should be used in conjunction with appropriate seeding on disturbed soils in steep slope and riparian areas. Matting should be secured in place with staples or wherever possible, live stakes of native trees. Straw mulch and tall fescue should not be used in riparian areas. 6. Compensatory mitigation for impacts to 210 linear feet of streams at a replacement ratio of 1:1 is required. We understand, based on the 401 Certification Application, that you have chosen to perform compensatory mitigation for impacts to streams through the North Carolina Ecosystem Enhancement Program (EEP). 7. All channel relocations will be constructed in a dry work area and stabilized before stream flows are diverted. Channel relocations will be completed and stabilized, and must be approved on site by DWQ staff, prior to diverting water into the new channel. Whenever possible, channel relocations shall be allowed to stabilize for an entire growing season. Vegetation used for bank stabilization shall be limited to native woody species, and should include establishment of a 30--foot wide wooded and an adjacent 20 foot pride vegetated buffer on both sides of the relocated channel to the maximum extent practicable. A transitional phase incorporating coir fiber and seedling establishment is allowable. Also, riprap may be allowed if it is necessary to maintain the physical integrity of the stream, but the applicant must provide written justification and any calculations used to determine the extent of riprap coverage area. 8. The dimension, pattern and profile of the stream, above and below the crossing, should not be modified. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 9. Native riparian vegetation (e.g. rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) must be reestablished within the construction limits of the project by the end of the growing season following completion of construction. 10. Any riprap placed for bank stabilization should be limited to the streambank below the high water mark, and vegetation should be used for stabilization above the high water elevation. Riprap should not be place in the active thalweg channel or placed in the streambed in such a manner that precludes aquatic life passage. Bioengineering boulders or structures should be properly designed, sized and installed. It. Heavy equipment should be operated from the banks rather than in the stream channels in order to minimize sedimentation and reduce the introduction of other pollutants into the stream. 12. All mechanized equipment operated near surface waters must be regularly inspected daily and maintained to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 13. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. Mr. J. B. Setzer, P.E. September 15, 2006 Page Three 14. All work in or adjacent to stream waters shall be conducted in a dry work area. Approved BMP measures from the most current version of NCDOT Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and other diversion structures should be used to prevent excavation in flowing water. 15. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is prohibited. 16. If concrete is used during construction (e.g., headwalls), a dry work area should be maintained to prevent direct contact between curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and fish kills. 17. No rock, sand or other materials shall be dredged from the stream channel, except where authorized by this certification. 18. The permittee and its authorized agents shall conduct its activities in a manner consistent with State water quality standards (including any requirements resulting from compliance with §303(d) of the Clean Water Act) and any other appropriate requirements of State or Federal law. If DWQ determines that such standards or laws are not being met (including failure to sustain a designated achieved use) or that State of Federal law if being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and modify this certification. 19. This certification does not authorize the discharge of waste rock and dirt into the stream or riparian zone except for permitted areas associated with the bank stabilization work. 20. 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. 21. Upon completion of the project, the NCDOT Division Engineer, shall complete and return the enclosed "Certificate of Completion Form" to notify NCDWQ when all work included in the §401 Certification has been completed. This form shall be returned to the Transportation Permitting Unit of the NC Division of Water Quality, 2321 Crabtree Blvd., Suite 250, Raleigh, North Carolina 27604. 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, which conforms to Chapter 150B of the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center, Raleigh, N.C. 27699-6714.

The original permit application dated February 10, 2006 included three pipe extensions totaling 54 linear feet of impact to an unnamed tributary to Crabtree Creek. Upon further review, NCDOT inadvertently left a 210-foot channel change off of the original permit application. The channel change is necessary due to the location of a barn on the eastside of the road and will be constructed from Sta. 17+40 to 19+50. The new channel will provide a wider vegetated buffer area between the road and the new stream channel. I have enclosed a revised PCN application (impact table), photos and stream relocation plans for Site 4. Natural channel design techniques were utilized and the new channel will be a 134a stream type. The channel will be a step-pool complex with cross vanes installed every (+/-) 25 feet to maintain channel stability. The new channel will be constructed in the dry and will be seeded and matted with coconut fiber before water is diverted. The stream banks will also be planted with native woody vegetation later this winter to provide long term stability. Impacts to Waters of the United States In order to construct the project in accordance with our current secondary road standards, it will be necessary to impact waters of the United States in the French Broad River Basin. Specifically, NCDOT is requesting to conduct a channel change and extend/replace three metal culverts in unnamed tributaries to Crabtree Creek (DWQ Class: Q.

An un-named tributary to Crabtree Creek runs adjacent to the existing gravel road. This will require relocating the stream along approximately 210 feet of the road to accommodate the new fill slope. Project Description This road is a dead end road and provides access to homes in the area. The existing stream segment is in a pasture in a Type II valley. The lower portion of the watershed is pasture. The stream is impacted by the land use and grazing. The stream is proposed to be relocated away from the road which will increase its length through the meander to 227 feet. The cross pipe at the end of the segment will be increased in size and extended approximately 8 feet. A headwall will be used to limit the length of extension necessary. Plans, profile, and cross sections are attached. Morphological Stream Classification The Rosgen stream classification system was used to classify the stream. Several factors made this difficult. Grazing and the pasture adjacent to the stream obscured bank full indicators. The stream appeared to be cutting down into a "G" type channel in some areas. Also the cross pipe on the lower end of the segment restricts flows that approach bank full. This effectively flattened the gradient for 100 feet to 150 feet upstream of the culvert at higher flows. The cross section at 154 was not useful in determining bank full since it was within this affected area. In addition, slight shifts in the location of the bank full elevation influenced the resulting classification. The upper cross section was classified as a "134" with a low width-depth ratio. This was attributed to the stream cutting down to a "G" type channel. The middle section of the existing stream classified most nearly to a "C" type channel due to the influence of the culvert restriction. A third cross section was taken at roadway station 23+50, approximately 400 feet upstream of the section to be relocated. The left bank was functioning to some degree as a point bar and was free to adjust at this location in a bend to the left. This cross section was used to verify cross section area, since it appears that this stream has a low bank full cross section area compared to the regional curve. This cross section most nearly classified as a "B" type stream. The bank full width was wide at this point to capture area outside of the slight berm adjacent to the main flow. This contributed to the apparent low entrenchment ratio and high width-depth ratio. Since this was not representative of the majority of the stream length studied, the "134" classification was considered to be the most stable for this reach. The Valley Type II with some flood plain would support the type "B" classification. Downstream of this section, the valley transitions to a Type VIII with a broader flood plain. A table of morphological characteristics and supporting data is provided in the following pages. Reference Reach The reference reach used is a "B4a" type stream in Jackson County in Nantahala National Forest. A parcel of private land is held within this watershed, but it is also wooded. The local slope at the cross section at 140 feet was most similar to the stream to be relocated, although overall it was slightly steeper. The classification data was near the average for this classification. A National Forest employee related that this area was extensively logged during the first half of the 1900's. Heavy impacts from logging practices in this era have been obscured by reforestation. White pines in the vicinity appear to be 40 - 50 years old. Site Maps 'Location maps of the site and the reference reach are shown on the following pages. Site Plans Plans for the relocation include the plan view, a profile view showing grade control, a typical section, and details of cross vanes used for stability. Biological Community Types The existing stream is in a pasture and is grassed almost exclusively within the riparian zone. At some locations it is immediately adjacent to the roadway. The stream rating was improved by the extensive amount of gravel and cobble in the stream bed and banks. The proposed stream will be separated from the road for most of its length, which should allow better habitat to develop. Woody vegetation in the riparian zone will also be an improvement. Stability Enhancements The lateral stability of the existing stream will be enhanced by the configuration of the stream channel and by woody vegetation. The width-depth ratio and entrenchment ratio will be restored to values more representative of the stable "B" reference cross sections. Vertical stability of the existing stream is supported by large cobbles and several in the boulder category and are expected to be present in the new channel. Prior to diverting the stream into the new channel, larger substrate materials should be transferred from the old channel and utilized in the proposed stream channel. Other measures to provide stability in the relocated section include grade control with rock weirs and decreased slope between steps. Bank erosion calculations indicate that sediment loss is on the order of 5 times the stable reference reach. Stability enhancements will address the major factors contributing to the instability of the existing stream. Sediment Transport The bed surface pebble count indicates a bimodal distribution with a sediment supply in the range of .2 mm to .5 mm on the lower end. This is likely attributable to high rates of runoff due to the amount of pasture in the watershed, although much of it may be originating from the stream banks. This sediment supply is expected to remain. Although stabilizing the road surface with pavement will reduce this source, there are other private roads and driveways. Entrainment calculations on the existing channel indicated that particles of 150 mm to 190 mm could be transported. Although a pavement/subpavement particle distribution was not done, a particle count of the full reach indicated only 4 particles larger than 180 mm. These could be attributed to bank sources and did not appear to be moving. The proposed stream is designed to transport particles up to 200 millimeters. The step spacing should result in a relatively uniform bankfull water surface slope at higher flows, which should transport the available sediment load. Care should be taken to avoid long step spacings which will isolate the slope between steps and result in a local slope that is insufficient to transport sediment particle sizes. Stability control will be maintained with the use of rock weirs. Buffer and Planting Requirements Native grass seeding and mulching will be performed on the disturbed areas adjacent to the stream for near term erosion control. Stream bank reforestation will be planted along both stream banks. Coir fiber mat will be installed on the stream banks where live staking is to be planted as shown on the stream bank typical cross section and in locations as directed by the Engineer. Standard seeding and mulching and reforestation specifications are included by reference and can be provided upon request. Potential Problems The location of the existing and proposed stream in a pasture is a potential problem. Although there were no stock in the pasture at the time, future use for grazing and watering could cause erosion of the stream banks.

Review of your application revealed it was lacking necessary information required for making an informed permit decision. The permit application was deficient in the following areas: • When reviewing the supporting information attached to the application, it was noted that a stream segment (210 linear feet) is to be relocated adjacent to the roadway. The application did not include this activity as impact or provide a stream mitigation/relocation plan. Please revise the application and provide a stream relocation plan for this project. Therefore, pursuant to 15A NCAC 2H .0507(a)(5), we will have to place the permit application on hold until we receive the requested information. Furthermore, until the NC Division of Water Quality receives the information, we request (by copy of this letter) that the US Army Corps of Engineers place the permit application on hold. Hopefully, we can work together to expedite the processing of your permit application. If you have any question or require additional information, please contact Mike Parker at 828-296-4500.

EASLEY GOVERNOR LYNDO TIPPETT SECRETARY February 10, 2006 Mr. Steve Lund, NCDOT Regulatory Project Manager ^ U.S. Army Corps of Engineers of) 0254 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 Subject: Nationwide 14 Permit Application SR 1511 - Reeves Cove Road Haywood County State Project No. 14C.044072 (DWQ Minor Permit Fee $200) Dear Mr. Lund: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, and pave SR 1511, Reeves Cove Road, in Haywood County from the intersection of SR 1503 for a distance of 0.48 miles to a dead end. This proposal entails widening and paving the existing gravel road to a standard 18-foot roadway. The proposed improvements of SR 1511 have been identified as necessary maintenance and safety improvements. Funds have been allocated for this project, and NCDOT would like to perform these activities sometime during the 2005-06 paving season. I am sending a straight-line diagram with the proposed erosion control and construction limits along this project. In addition, I am sending a typical section of the road, cross sections, drawings for pipe culvert replacements as well as a marked county map and USGS quad map. We propose to install the new culverts slightly below the existing streambed elevations where bedrock is not encountered to minimize impacts to aquatic habitats and allow the existing stream gradients to remain as unchanged as physically possible. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. There are no records of threatened and endangered species for the unnamed tributary. Additionally, there are no records listed for the entire Crabtree Creek watershed. These proposed culvert replacements and extensions are on small (3 feet in width) tributaries and 2 are not of sufficient size to support mussels. For these reasons, there will be "no effect" on threatened or endangered species. Impacts to historic or cultural resources are not anticipated. If the State Historic Preservation Office (SHPO) and the Office of State Archaeology determines that further investigations are required, NCDOT will conduct the appropriate site investigations and obtain compliance from SHPO prior to project construction. The best management practices will be used to minimize and control sedimentation and erosion on this project. The construction foreman will review all erosion control measures daily to ensure sedimentation and erosion is being effectively controlled. If the planned devices are not functioning as intended, they will be immediately replaced with better devices. The rock silt screens and other erosion control devices will be in place prior to pipe culvert construction and will remain in place until the project is stabilized. Impacts to Waters of the United States The unnamed tributaries are not shown on the USGS topographic map. However, the streams have well defined channels and perennial flow. The channels are composed of cobble, gravel and sand. The channels lack vegetation. For these reasons, we believe these streams are under the jurisdiction of the U. S. Army Corps of Engineers. In order to construct the project in accordance with our current secondary road standards, it will be necessary to impact waters of the United States in the French Broad River Basin. Specifically, NCDOT is requesting to extend/replace three metal culverts in unnamed tributaries to Crabtree Creek (DWQ Class Q. Listed below is a summary of the proposed impacts.

Impacts cannot be avoided. Culverts must be extended in order to gain the necessary width to improve SR 1511 to current NCDOT standards. All pipe extensions will be placed below the existing; stream bed gradient so natural substrate can be re-established. 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 9 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 NCEEP concurrence shall be placed on hold as incomplete.
