Date: 03/30/07 Prepared by: MUI~.KEY F..€^,lINE~RS ~: CC3hdS~.IET~NTS Little White Oak Creek Stream Restoration Site Polk County, NC General Description The proposed Little White Oak Creek Stream Restoration Site (project, site) is a large stream restoration and conservation easement acquisition project intended to create a contiguous, high quality ecosystem restoration project. The project is located in Polk County, North Carolina approximately 2.5 miles east southeast of the community of Mill Springs, approximately 0.6 mile north of Exit 167 at the intersection of NC Highway 9 and US 74. Mulkey, Inc. (Mulkey, the Designer) was contracted through the North Carolina Department of Environment and Natural Resources, Ecosystem Enhancement Program to provide turn- key services for this project with the goal of restoring a stable stream system which will be used for stream mitigation. The proposed design for this project is based on natural channel design methodologies. The project is located along the Little White Oak Creek, the South Branch of Little White Oak Creek, and its tributaries. The project lies within two parcels that have historically been used fox pasture and forest land. The site has been used as a pasture fox cattle for the past 50 years. There are approximately 200 grazing cattle and horses currently utilizing the pastures. The livestock have not been fenced from the streams at any location within the site. This continual livestock access to the streams has resulted in substantial erosion along the stream banks, incision of the channels, channel widening in some areas, and poor bed form diversity throughout the site, as well as reduced water quality due to the introduction of fecal matter into the stream system. The property owner explained that many of the streams at the site, particularly the smaller tributaries, were historically maintained through channelization, dredging, and clearing of the riparian buffer. Fecal and nutrient contamination to streams within the site is currently a concern. The two main streams at the site are third order streams, Little White Oak Creek at the north end of the site and South Branch of Little White Oak Creek at the south end of the site. These two streams converge at the center of the site as Little White Oak Creek to form a fourth order stream. The site also includes one second order unnamed tributary and five first order unnamed tributaries. The headwaters of the Little White Oak Creek are located southeast of Lake Adger and north and east of Little White Oak Mountain then flow in an easterly direction through the project site. The drainage area of Little White Oak Creek as it enters the project area is approximately 3,400 acres (5.3 square miles). The headwaters of the South Branch of Little White Oak Creek are located north and east of Fox Mountain and flow east to its confluence with Little White Oak Creek. The drainage area of the South Branch of Little White Oak Creek as it enters the project area is approximately 2,560 acres (4.0 square miles). The overall drainage area of the project is 7,124 acres (11.1 square miles). Goals and Objectives The overall goals for this stream restoration project are to improve water quality as well as to improve instream and terrestrial wildlife at the site and downstream. These goals are to be met by accomplishing the following specific tasks: • Restoring the stability of the project stream reaches using Rosgen's natural channel design methodologies; • Reducing the rate of streambank erosion along the project stream reaches; • Elimination of mass wasting along the project stream reaches; and • Reconnecting the streams to their historic floodplains, or constructing bankfull benches; • Restoring a forested riparian buffer, thereby wildlife cover and travel-corridors; Successfully accomplishing the above goals will also enable the project to be utilized fox mitigation credit. Proposed Restoration Mulkey has acquired 55.3 acres of conservation easement for the State of North Carolina to provide buffer for the project site. The construction of the project will include restoring or natural pattern, dimension, and profile along all each of the project stream reaches. This will be accomplished by constructing a new stream channel for each project stream reach, thereby restoring pattern, dimension, and profile appropriate for the site conditions and based on reference reach parameters. Natural channel design methodologies will be utilized exclusively and will include the use of rock and log structures, impervious stream channel plugs, erosion control matting, bankfull benches, soil restoration, including topsoil stockpiling and reuse, amendment of soils, and site planting preparation, as well as vegetation planting, including transplants, live stakes, seeding, and bare roots. Erosion Control Erosion control during construction operations will be provided through the use of pump- around operations, impervious dikes, sediment bags, silt fence, tree protection fence, staging areas, at-grade stream crossings, and gravel construction entrances. Careful phasing and strict sequencing, along with consistent maintenance of all erosion control measures will be required at all times during construction. The project is phased such that each phase of work must be completed before work on another phase can be initiated. The phasing is designed to ensure the proper installation and implementation of erosion and sedimentation controls while allowing the contractor the option to complete some of the phases out of sequence, depending upon weather and/or site conditions. For example, in the situation where unusually wet site conditions are encountered or expected, the contractor might elect to begin work on one of the higher, and likely drier, smaller tributaries instead of beginning work on the lower, and likely wetter larger stream reaches. Again, regardless of the sequencing of the phases, each phase will be completed prior to beginning work on another phase. On-site hauling will be restricted to existing access roads to minimize erosion potential. Gravel construction entrances will be installed at each location where construction traffic is proposed to enter and exit the site. These locations include NC Highway 9, John Sheehan Road, and Whiteside Road as noted on the plans. The proposed area of disturbance is 82.8 acres, and is limited to the actual work areas where channel and floodplain benches will be excavated, the in-stream structures will be installed, the spoil areas at these locations, and the haul roads and staging areas as noted on the plans. Silt fence will be installed around staging areas and along access roads as noted on the plans. Additional silt fence will be installed if warranted by site conditions. A stream pump-around operation is proposed for use on all streams and will be functioning prior to excavation of the channel section. Livestock will be removed from the construction area prior to excavation to reduce impacts of sedimentation from animal traffic. Mature vegetation outside of channel and floodplain bench construction will be protected from disturbance, to the maximum extent practicable. All disturbed areas will be planted with temporary and permanent seeding, and will also be mulched. In addition, restored sections of the stream channel will be further stabilized through the installation of coin fiber erosion control matting. Construction of the project will be carried out in fifteen phases to ensure adequate implementation of erosion and sedimentation controls, minimization of sedimentation, channel stability, and maximum vegetation establishment and survival. The proposed construction sequence outlining these fifteen phases is included below: PHASE 1 LNESTOCK MOVEMENT, MOBILIZATION, AND ESTABLISHMENT OF GENERAL EROSION CONTROL MEASURES 1. Coordinate and complete all necessary livestock movement, exclusion, and containment activities with the landowner. 2. Identify and locate staging areas, stockpile areas, construction entrances, stream crossings required for construction access, limits of silt fencing, limits of tree protection fencing, and construction access roads as shown on plans. 3. Install construction entrances. 4. Install stream crossings required for construction access. 5. Stockpile materials in designated staging areas. 6.

NOTE: With approval from the Designer, the Contractor may complete Phases 2 through 13 out of sequence, dependant upon weather and/or site conditions. Regardless of the sequencing of the phases, each phase will be completed prior to beginning work on another phase. Upon the completion of each phase, the Contractor shall schedule an inspection of the phase by the Designer. The Contractor must have written approval from the Designer that the phase has been completed to satisfactory standards before beginning another phase.

The project site is not located in an CAMA county. 2.0 Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) The LWO is a full delivery project located in rural Polk County. The property has been utilized for agricultural production for at least 70 years. Mulkey was unable to identify property adjacent to the site which was zoned as commercial or industrial. Mulkey staff spoke with Cathy Ruth, Polk County Planning and Zoning on September 13, 2006, concerning zoning. Ms. Ruth stated that no commercial or industrial zoning has taken place on the subject property or adjacent properties. A limited Phase I was also conducted during July 17-28, 2006. The methodology consisted of communicating with the landowner of the property and completing a visual assessment of the site. As a result, Mulkey staff were unable to identify any known or potential hazardous waste sites within or adjacent to the project area. Polk Central Elementary School is located north of HWY 9 and is surrounded by the subject property. The school does have a sand filter water discharge pipe that is an NPDES permitted discharge into the South Branch of the Little White Oak Creek. Mullcey is currently working with the school system develop alternatives for this discharge. Regardless of the outcome of these decisions, the discharge is not anticipated to have any adverse effect on the restoration project. A farmstead is located on the same property as the project. With most farmsteads, there is the potential that hazardous substances could exist such as pesticides and other materials. Based upon the onsite assessment performed, it is not anticipated that the farmstead poses any impact from hazardous substances to the project area. 3.0 National Historic Preservation Act (Section 106) Concurrence letters were sent to the State Historic Preservation Office (SHPO) on July 7, 2006 and to the Eastern Band of Cherokee Indians (EBCI) on August 2, 2006. Mulkey received a letter of response dated August 3, 2006, from the SHPO office which recommended a comprehensive survey of the project area. Mulkey also received a letter of response from the EBCI dated August 29, 2006, that recommended a phase I archeological survey. On. September 5, 2006, Mulkey subcontracted with Edwards-Pitman Environmental, Inc. (Edwards-Pitman) to complete an archeological phase I in a manner that would proceed to phase II in order to determine eligibility if necessary. The field assessment of the phase I archeological survey was completed on September 15, 2006. There were no eligible sites identified within the Area of Potential Effects (~E)• Documentation is included in Appendix B - Scoping Letters, Appendix C -Agency Response Letters, and Appendix D -Archeology. 4.0 Uniform Relocation Assistance and Real Property Acquisition Policies Act (Uniform Act) The LWO project is a full delivery project for EEP. The property acquisition of the LWO project will be completed after the executed contract with the EEP. Property owners were notified on August 17, 2006 by letter that the EEP does not have right of condemnation and what the fair market value of the land is believed to be. Documentation is included in Appendix E - URLA & RPAPA. 5.0 American Indian Religious Freedom Act (AIl2FA) The LWO project is located in a county listed as territory of the EBCI. As noted in comments with Section 106, a phase I archeological survey was completed. No eligible sites were identified within the APE. Documentation is included in Appendix D -Archeology. 6.0 Antiquities Act (AA) The LWO project is not located on Federal lands. 7.0 Archeological Resources Protection Act (ARPA) The LWO project is not located on Federal lands or Indian lands reservation. 8.0 Endangered Species Act (ESA) Mulkey performed a review of mapping for compliance with ESA as well as an in-field survey for the listed species. 8.1 Federally Protected Species As of the March 8, 20061ist, the USFWS identified two Threatened (T) and one Endangered (E) species as occurring in Polk County. North Carolina National Heritage Program maps (updated July, 2006) were reviewed to determine if any protected species have been identified near the project area. This map review confirmed that no federally protected species and no designated critical habitat areas are known to occur within a 1-mile radius of the study area. A description of habitat requirements and a biological conclusion is provided for these species in the following sections. 8.1.1 Dwarf-flowered heartleaf (Hexastylis naniflora) Federal Status: Threatened State Status: Threatened 2 The dwarf-flowered heartleaf has the smallest flower of any North American Hexastylis. Most flowers are less that .4 inch long, with narrow sepal tubes (never more than .28 inch wide). The jug-shaped flowers range from beige to dark brown, sometimes greenish or purplish. Leathery evergreen leaves are dark green and heart-shaped. Dwarf-flowered heartleaf commonly occurs in areas of acidic sandy loam soils found along bluffs and nearby slopes, hillsides and ravines, and in boggy areas adjacent to creekheads and streams. Soil type is the most important habitat requirement (Pacolet, Madison, or Musella types). Abundant sunlight in early spring is necessary for maximum flowering and seed production. Flowering generally occurs between Mid-March and early June. Biological Conclusion: No Effect Appropriate habitat for dwarf-flowered heartleaf consisting of acidic sandy loam .soils (specifically Madison and Pacolet types) is not present within the study site but is present within the property encompassing the study site. A review of NCNHP records showed no occurrence of dwarf-flowered heartleaf within a 1-mile radius of the project site. In addition, a pedestrian survey was conducted by qualified biologists .from Mulkey on July 17, 2006. No occurrence of dwarf-flowered heartleaf was found on-site during the plant-by-plant survey. Therefore, project construction will have No Effect on this species. 8.1.2 Small whorled pogonia (Isotria medeoloides) Federal Status: Threatened State Status: Endangered Small-whorled pogonia is a small perennial member of the Orchidaceae with long, pubescent roots and a smooth, hollow stem 3.8 to 10 inches (9.5 to 25 centimeters) tall terminating in a whorl of 5 or 6 light green, elliptical leaves that are somewhat pointed and measure up to 1.6 to 3.2 inches (8 by 4 centimeters). It is distinguishable from similar species such as purple fiveleaf orchid (I. verticillata) and Indian cucumber-root (Medeola virginiana) by its hollow stem. These plants arise from long slender roots with hollow stems terminating in a whorl of five or six light green leaves. The single flower is approximately 1 inch (2.5 centimeters) long, with yellowish- green to white petals and three longer green sepals. This orchid blooms in late spring from mid- May to mid-June. This plant is believed to be self-pollinating by mechanical processes. Populations of this plant are reported to have extended periods of dormancy and to bloom sporadically. This small spring ephemeral orchid is not observable outside of the spring growing season. The small whorled pogonia grows in young as well as maturing (second- or third-growth) forests, but typically grows in open, dry deciduous woods and areas along stream with acidic soils. It also grows in rich, mesic woods in association with white pine and rhododendron. Habitat is characterized by sparse to moderate ground cover, open understory canopy, and proximity to clearings such as roads, streams or canopy gaps. When it occurs in habitat where there is relatively high shrub coverage or high sapling density, flowering appears to be inhibited. Decaying organic matter such as wood litter from fallen limbs and trees, leaves, bark or stumps may be important for plant growth as various types of decaying vegetation are found in habitat of extant populations (von Oettingen, 1992). Biological Conclusion: No Effect Suitable habitat for the small whorled pogonia is not present in the project study area. A pedestrian survey was conducted by qualified biologists from Mulkey on July 17, 2006. No occurrence of small whorled pogonia was found on-site during the plant-by-plant survey. In addition, NCNHP does not list any occurrences of the small whorled pogonia within a 1- mile radius of the project site. Therefore, project construction will have No Effect on this species. 8.1.3 White irisette (Sisyrinchium dichotomum) Federal Status: Endangered State Status: Endangered The white irisette is a small perennial herb that grows in adichotomously-branching pattern, reaching heights of approximately 4.3 to 7.9 inches (11 to 20 centimeters). The basal leaves, usually pale to bluish green, are from one-third to one-half the height of the plant. They are long- attenuate, with an acuminate apex. The tiny white flowers are 0.3 inches (0.75 centimeters) long and appear from late May through July in clusters of four to six at the ends of winged stems. The stems have from three to five nodes, each with one to three winged peduncles 1.6 to 2.8 inches (4 to 7 centimeters) long and 0.02 to 0.04 inches (0.06 to 0.09 centimeters) wide. There are successively shorter internodes between the dichotomous branches. Individual plants may have 10 or more stems arising from the fibrous roots. The fruit is a round, pale to medium brown capsule containing three to six round or elliptical black seeds. The dichotomous branching pattern and white flowers combine to distinguish this herb from other species within the genus (Feil, 1995). White irisette closely resembles narrow-leaved blue-eyed grass (Sisyrinchium angustifolium). It is distinguished by the branching from the first node, with plant parts becoming noticeably smaller above. Blue-eyed grass usually has one node, with no noticeable reduction in the top of the plant. This species occurs on rich, basic soils probably weathered from amphibolite. It grows in clearings and the edges of upland woods where the canopy is thin and often where down-slope runoff has removed much of the deep litter layer ordinarily present on these sites. It is found on mid-elevation mountain slopes with a southeast to southwest aspect and shallow soils due to rockiness or steep terrain. The Irisette is dependent on some form of disturbance to maintain the open quality of its habitat. It is also grows in open disturbed sites such as woodland edges, power line easements, and roadsides (Feil, 1995). Biological Conclusion: No Effect Suitable habitat for the white irisette consisting of clearings and the edges of upland woods where the canopy is thin is present in the project study area. A pedestrian was conducted by qualified biologists from Mulkey on July 17, 2006. No occurrence of white irisette was found on-site during the plant-by-plant survey. In addition, NCNHP does not list any occurrences of white irisette within a 1-mile radius of the project site. Therefore, project construction will have No Effect on this species. 8.2 Federal Designated Critical Habitat In addition to species listed as endangered or threatened, areas designated as Critical Habitat are also recorded under Section 4 of the ESA. As defined by USFWS, critical habitat is "specific geographic areas, whether occupied by a listed species or not, that are essential for their conservation and that have been formally designated by rule published in the Federal Register" (USFWS, 2005). As of the March 8, 2006 list, no critical habitat areas are listed by USFWS as ,, occurring in Polk County. 4 8.3 Federal Species of Concern and State Listed Species Federal Species of Concern (FSC) are not legally protected under the Endangered Species Act and are not subject to any of its provisions, including Section 7. Species designated as FSC are defined as taxa which may or may not be listed in the future. These species were formerly Candidate 2 (C2) species or species under consideration for listing for which there is insufficient information to support listing. In addition to the federally listed species referred to above, the USFWS lists 11 FSC as occurring in Polk County as of the March 8, 2006 protected species list. In addition, the NCNHP list (dated July 2006) included 18 species as receiving protection under state laws. Natural Heritage Program maps were reviewed to determine if any FSC or state protected species have been identified near the project area. This map review confirmed that no FSC or state species are known to occur within a 1-mile radius of the study area. 9.0 Executive Order 13007 (Indian Sacred Sites) The LWO project is not located on Federal lands.

Pha$e T Archaeological Survey requested. The Tribal Historic Preservation 0~'tee of the Eastern Band of Cherokee Indians is in receipt of the shave-referenced project information and appzeciates the invitation to participate as a reviewing party in compliance with 35 C.F.R. 800. Because the site is located close to riveritte and topographic environments that contained prehistoric and historic Native American habitation, the EBCI THPO requests a phase I archaeological survey. The location of the project lies within the aboriginal temitary of the Cherokee people. This area may have cultural, archaeological, ar religious significance to the Eastern Band of Cherokee Indians. The rich cultural and traditional affiiiatian with the river valleys afNotth Carolina obligates the EBCT THI'O to protect tribal cultural resources. These potential cultural resources may be impacted due to the nature ofground-disturbance required for this undertaking. Disturbance of ethnographic sites, such as traditional Native American camp sites ar town sites, can reduce the cultural and interpretative significance for both sovereign American Tndaan nations and the United States. Therefore, the EBCI THPO requests a phase I archaeological survey be conducted. Section 106 guidelines (36 C.F.R. 840) of the National Historic Preservation Act of ].966 mandate that you contract with an archaeologist that meets the Secretary of the Department of the Interior's professional guidelines. This should be done before we can offer our concurrence that the proposed undertaking will not have an effect on known ar unknown cultural resources si~trficant to our tribe. A phase I archaeological survey should take place throughout the entire Area of Potential Effect (A1~E) to ensure that any potential cultural resources are identified. As a consulting party we request that you send all information pertaining to cultural resources within the above-referenced project's Al'E for our review, comment, and final concurrence. 1~ATE: 29 -- August - 06 Aug, 30. 2006 2:38AM No. 1110 P. 3 ~f you have any questions oz concerns, please feel free to contact me at (~28) 488-423?, ext. 2. ~., Tribal Historic Preservation Specialist Eastern Band of Cherokee Indians Cc: Tim Baumgartner 4}y~ S~ ~ 4 N ~ ~°~ ~~ n ~t puM North Carolina Department of Cultural Resources State Historic Preservation Office Peter B.

Office of Archives and History Division of Historical Resources David Brook, Director We have determined that the project as proposed will not affect any historic structures. There are no known recorded archaeological sites within the project boundaries. However, the project area has never been systematically surveyed to determine the location or significance of archaeological resources. Based on the topographic and hydrological situation, there is a high probability for the presence of prehistoric or historic archaeological sites. We recommend that a comprehensive survey be conducted by an experienced archaeologist to identify and evaluate the significance of archaeological remains that may be damaged or destroyed by the proposed project. Potential effects on unknown resources must be assessed prior to the initiation of construction activities Two copies of the resulting archaeological survey report, as well as one copy of the appropriate site forms, should be forwarded to us for review and comment as soon as they are available and well in advance of any construction activities. A list of archaeological consultants who have conducted or expressed an interest in contract work in North Carolina is available at uTww.arch.dcr.state.nc.us/consults.htm. The archaeologists listed, or any other experienced archaeologist, map be contacted to conduct the recommended survey. The above comments are made pursuant to Section 106 of the National Historic Preservation Act and the Advisory Council on Historic Preservation's Regulations for Compliance with Section 106 codified at 36 CFR Part 800.

Comments from the Commission are provided under provisions of the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661 et seq.) and the National Environmental Policy Act (42 U.S.C. 4332 (2)(c). The Commission does not anticipate any major resource concerns with this project provided the stream channel dimensions, patterns, and profiles reflect stable, reference conditions. Overly. sinuous stream channels should be avoided. We recommend using container trees in the outside channel bends to expedite long-term stability.

After digging shovel tests at a 30 meter uiterval along each stream within the project area boundaries, we recorded a single isolated. find, a piece of metavolcanic debitage related. to stone tool production. Because it consists of only a single artifact that likely eroded down from a nearby ridgetop, this site is considered ineligible for further testing. Therefore, no fiuther archaeological ~~~ork is mandated within the APE. If you have any further questions, please give me a call or send me an e-mail. 1 should be in the office for most of the day.
