Polk County DWQ Project No. 060111 NCSR 1154 (Big Hungry 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 20 linear feet in two (2) unnamed tributaries to Pulliam Creek (20 linear feet of new pipe and temporary dewatering), in order to make improvements to NCSR 1154 (Big Hungry Road) in Polk County. The project should be constructed in accordance with your application dated January 17, 2006 (received January 23, 2006), including the environmental comments made in the application letter. After reviewing your application, we have decided that this fill is covered by General Water Quality Certification Nos. 3404 and 3366, corresponding to the U.S. Army Corps of Engineers Nationwide Permit Numbers 14 and 33. 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 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 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. 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 Sutface Mining Manual.

B. Setzer, P.E. February 15, 2006 Page Two d. Any 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 date that the Division of Land Quality has released the project. 4. The NC Wildlife Resources Commission is requesting that in-stream work and land disturbance within the 25-foot wide buffer zone, not be conducted during the trout-spawning season of October 15 through April 15, to protect the egg and fry stages of trout from off-site sedimentation during the road construction project. 5. 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 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. 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. 6. Adequate sedimentation and erosion control measures must be installed and maintained on the project site to minimize sediment transport to downstream aquatic resources. Temporary 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. 7. The dimension, pattern and profile of the stream, above and below this work, should not be modified by widening or narrowing the stream channel or reducing the stream depth. Disturbed floodplains and streams should be restored to natural geomorphic conditions. 8. Stormwater shall 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 diffuse flow. 9. Riparian vegetation should be preserved to the extent possible. Native trees and shrubs (e.g. Rhododendron, dog hobble, willows, alders, sycamores, dogwoods, black walnut and red maple) should be restored wherever possible along the repaired slope and streambank to reestablish the riparian zone and to provide long-term erosion control. 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 stream channels in such a manner that it impedes aquatic life passage. 11. Heavy equipment should be operated from the bank rather than in the stream channels in order to minimize sedimentation and to reduce the likelihood of introducing other pollutants into the stream. This equipment should be inspected and maintained daily to prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials. 12. Rock check dams at culvert outlets should be removed at project completion to avoid impeding aquatic life movement. 13. Excavation in the stream channel should be conducted in the dry, if possible. Sandbags, cofferdams, flexible pipe or other diversion structures should be used to minimize excavation in flowing water. 14. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface waters is strictly prohibited. 15. If concrete is used during culvert 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 fish kills. 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 bank stabilization work. In-stream dredging has catastrophic effects on aquatic life, and disturbance of the natural form of the stream channel will likely cause downstream erosion problems, possibly affecting other landowners. Mr. J. B. Setzer. P.E. February 15, 2006 Page Three 17. 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. 18. All work shall be performed during low flow conditions (below bankfull). 19. Upon completion of the project, the NCDOT shall complete and return the enclosed "Certificate of Completion " form to notify NCDWQ when all work included in the §401 Certification has been completed. The responsible party shall complete the attached form and return it to the Transportation Permitting Unit of the NC Division of Nater Quality upon completion of the project. The NCDOT is strongly advised to send in photographs upstream and downstream of each structure to document correct installation. 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. This certification and its conditions are final and binding unless you ask for a hearing. This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water Act. If you have any questions, please telephone Mr. Mike Parker of the Asheville Regional Office at 828.296.4500. Sincerely, Alan W.

STAT[ o STATE OF NORTH CAROLINA f V l?T oF? ti? sT0,,q? q ?n DEPARTMENT OF TRANSPORTATION RB?H MICHAEL F. EASLEY GOVERNOR January 17, 2005 Mr. Steve Lund, NCDOT Regulatory Project Manager U.S. Army Corps of Engineers 151 Patton Avenue, Room 208 Asheville, NC 28801-2714 Subject: Nationwide 14 Permit Application SR 1154, Big Hungry Road Polk County LYNDO TIPPETT SECRETARY State Project # 140.075026 (DWQ Minor Permit Fee $200.00) Dear Mr. Lund: The North Carolina Department of Transportation (NCDOT) is proposing to widen, grade, drain and pave SR 1154, Big Hungry Road, in Polk County. This proposal entails widening and paving the existing gravel road to a standard 18-foot roadway. The work is necessary to improve safety and reduce maintenance costs. Funds have been allocated for this project and NCDOT would like to perform this work during the 2005-06 paving season. Big Hungry Road is a dead end gravel road, which conveys only local traffic. I am enclosing a PCN, 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, drawings for the pipe culvert replacements, a marked county map and USGS quad map. The North Carolina Natural Heritage Database was checked for records of threatened and endangered species. There are no records for aquatic threatened or endangered species for the unnamed tributary of Pulliam Creek. Additionally, there are no records of aquatic threatened or endangered species for the entire Pulliam Creek watershed. The UT to Pulliam Creek is small (6 feet wide) and does not have sufficient flow to support mussels. The impacts from the culvert replacements will be minimal. Therefore, this project will have no effect on aquatic threatened or endangered species. 2 There are records of white irisette (Sisyrinchitun dichotoinunt), a federally endangered plant, from the nearby White Oak Mountain area and an excellent population exists along the right of way of Skyuka Mountain Road. The nearest record of the white irisette is approximately two miles from this project. Due to the proximity of a significant population of white irisette, Owen Anderson, Environmental Specialist with NCDOT, surveyed Big Hungry Road on December 7, 2005. The habitat along Big Hungry Road appears to be significantly different than the habitat along Skyuka Mountain Road. There is more pine, gradients are gentler and the forest is younger. No evidence of white irisette was detected on Big Hungry Road. Although December is not the optimum time of the year to detect white irisette, remnants of white irisette plants along Skyuka Mountain Road were still identifiable. For the above 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 sedimentation control measures during installation to ensure sedimentation is being effectively controlled. If the planned devices are not functioning as intended, they will be replaced immediately with better devices. The sedimentation control devices will be in place prior to pipe culvert removal and will remain in place until the new pipe is in place. Impacts to Waters of the United States The unnamed tributary to Pulliam Creek appears on USGS topographic maps. The stream appears to have perennial flow. The channel is well defined and is composed of sand and gravel. The channel lacks vegetation. For these reasons, we believe that the stream is under the jurisdiction of the U.S. Army Corps of Engineers. In order to replace these culverts, it will be necessary to impact waters of the United States in the Broad River Basin. Specifically, NCDOT is requesting to replace a metal culvert in an unnamed tributary to Pulliam Creek. (DWQ Class C, Tr). Listed below is a summary of the proposed impacts.

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. Water will be diverted during the installation of the pipe to minimize sedimentation. The pipe will be placed below the stream bottom to minimize fragmentation of aquatic habitat. Pavement widths have been reduced from 20' to 18' to minimize overall impacts to the proigct. At approx stations 23+00 and 29+50 through 31+50 where the small stream is fairly close to the road the staking offsets for clearing have been reduced from 5' to 0' in order to minimize the loss of canopy trees along the stream 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 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. Page 5 of 8 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:/ih2o.enr.state.ne.us/ncwetlands/stn-ni!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. N/A 2. Mitigation may also be made by payment into the North Carolina Ecosystem Enhancement Program (NCEEP).

Yes ? No ® If you answered "yes", provide the following information: 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. Zone* Impact (square feet) Multiplier Required Mitigation 1 3 2 1.5 Total * Zone 1 extends out 30 feet perpendicular from near bank of channel; Zone L extends an additional 20 feet from the edge of Zone 1. If buffer mitigation is required, please discuss what type of mitigation is proposed (i.e., Donation of Property, Conservation Easement, Riparian Buffer Restoration / Enhancement, Preservation or Payment into the Riparian Buffer Restoration Fund). Please attach all appropriate information as identified within 15A NCAC 2B .0242 or.0260. X.

These areas will require stage seeding and mulching. • Begin grading of roadway ditches. Place erosion control measures along roadway ditches as grading progresses and conditions allow. • Seed and mulch all disturbed areas as soon as any phase of grading is completed. (Note there are 15 working.days/30 calendar days to complete seeding and mulching. A working day is defined as a day exclusive of Saturday or Sunday during which weather conditions or soil conditions permit land-disturbing activity.) • Clean out and/or rework all temporary erosion control measures after any significant rainfall event (or as otherwise needed). These measures should be maintained until a permanent vegetative cover is established. Wet Pipe Installation Schedule • Install erosion control devices. • Remove material and existing pipe while limiting, as much as possible, material and sediment from entering the stream and/or escaping from the project. • Prepare pipe foundation while taking care to limit material and sediment from entering the stream and/or escaping from the project. Where possible new grade should be below the existing streambed. If needed, bedding material will be clean stone (especially in Trout and HQW waters). • Place new pipe and compact fill. • Install slope protection on outlet and inlet ends of pipe. Also complete ihstallation of erosion control measures and perform maintenance as needed on existing measures. 9 Establish permanent vegetation as soon as possible. PIPE DATA SR 1154 EXT.
