Specific plans and location information are described below and shown on the attached plans. This Public Notice and all attached plans are also available on the Wilmington District Web Site at www.saw.usace.army.mil/wetlands. Applicant: Duke Energy Carolinas, LLC Mr. Jonathan Wise 5657 Rays Dairy Avenue Morganton, North Carolina 28655 AGENT (if applicable): HDR/DTA Mr. James McRacken 400 S. Tryon Street WC2401 Charlotte, North Carolina 28285 Authority The Corps will evaluate this application and decide whether to issue, conditionally issue, or deny the proposed work pursuant to applicable procedures of Section 404 of the Clean Water Act (33 U.S.C. 1344)., Location The proposed project known as the Linville Embankment Seismic Stability Improvements (ESSI) is located on Lake James, near North Powerhouse Road, near Morganton, in Burke County, North Carolina (35.74238°N, 81.83567°W). The site contains wetlands and stream channels with indicators of ordinary high water marks that are tributaries to the Catawba River. The Catawba River ultimately flows to the Atlantic Ocean through the Santee-Cooper River system in South Carolina. Existing Site Conditions The Bridgewater Hydroelectric Development is owned and operated by Duke Energy and is located approximately eight miles west of Morganton, North Carolina, in Burke County. The Lake James reservoir was formed by the damming of three watercourses: the Catawba River by the Catawba Dam; Paddy Creek by Paddy Creek Dam; and the Linville River by Linville Dam. This project is associated with the ESSI of the Linville Dam on the Linville River. The impoundment of Lake James, an approximately 6,400-acre lake with approximately 150 miles of wooded shoreline, has changed the local topography and hydrology. Additionally, many of the surrounding hillsides have been cleared within the recent past and are regenerating as pine stands. Furthermore, many of the valley sections outside the project area have been largely converted to nursery plots for woody ornamental tree stock or are utilized for rural residential purposes. The topography of the project area is comprised of strongly sloping to very steep uplands with narrow, level floodplains along streams and wide, nearly level flood plains and gently sloping to strongly sloping stream terraces along the Catawba River. The normal pool elevation for Lake James is approximately 1,200 feet mean sea level (MSL). The approximate elevation at the bottom of the Linville Dam is 1,062 feet MSL, indicating an approximate drop in elevation of 13 8 feet. There are two offsite areas that are being studied for potential borrow to be used for the construction of the Linville Dam ESSI berm. These areas are the Paddy Creek Dam ESSI Tract and the Borrow Area 3. The Paddy Creek Dam ESSI Tract is made up of approximately 136- acres of disturbed and undisturbed land. This tract was largely used for borrow for the construction of the Paddy Creek Dam ESSI berm and for the location of work/support trailers and material lay-down. There were several areas of potential borrow soil that was not utilized during the Paddy Creek ESSI and the Bridgewater Powerhouse construction. These undisturbed borrow areas are slated to be used for the construction of the Linville Dam ESSI Project. The second parcel to be utilized for soil borrow to construct the Linville Dam ESSI Project berm is the Borrow Area 3 tract. This tract is made up of approximately 280-acres of disturbed and undisturbed land and is located approximately 1.8 miles down Powerhouse Road, southeast of the Linville Dam. Borrow material from this tract will have to be trucked to the Linville Dam ESSI Project via Powerhouse Road. The Linville Dam is an earthen embankment with grass covering the downstream slope. The pavement along the crest is an asphalt two-lane secondary road (S.R. 1233/Upper Powerhouse Road) maintained by the North Carolina Department of Transportation (NCDOT). Rip rap protects a majority of the upstream slope with the freeboard covered with rip rap to approximate elevation (EL) 1,200 transitioning to grass approximately 10 feet above full pond elevation. At the base of the downstream side of the Linville dam there is the existing Bridgewater powerhouse, new Bridgewater powerhouse, switchyard, and support buildings. 2 Much of the approximately 40-acre Linville Dam ESSI Project area and associated borrow and support areas are located within the Catawba River Basin have been modified and do not present the types of natural communities to be expected had the area and associated habitats have been left undisturbed. The major natural communities found on the Linville Dam ESSI Project are stream riparian and hillside upland habitats. The stream riparian areas and the wetlands are typically composed of the following: tulip poplar (Liriodendron tulipifera); red maple (Acer rubrum); river birch (Betula nigra); American sycamore (Platanus occidentalis); red mulberry (Morus rubra); mockernut hickory (Carya tomentosa); and sweetgum (Liquidambar styraciflua). Corresponding understory species are ironwood (Carpinus caroliniana); American holly (Ilex opaca); silky dogwood (Cornus amomum); alder (Alnus serrulata); and Chinese privet (Ligustrum sinense). Other common plants included giant cane (Arundinaria gigantea), browntop (Microstegium vimineum), Japanese honeysuckle (Lonicera japonica), soft rush (Juncus effusus), bog rush (Juncus biflorus), dotted smartweed (Polygonum punctatum), shallow sedge (Carex lurida), netted chainfern (Woodwardia areolata) and yellow violet (Viola pubescens var. pubescens). In the adjacent hillside uplands, the habitat consists of a mix of white pine (Pinus strobus), Virginia pine (Pinus virginiana), tulip poplar, sweetgum, and red maple. Other canopy species present were black cherry (Prunus serotina), American beech (Fagus grandifolia), river birch, and northern red oak (Quercus rubra). Understory trees and shrubs include ironwood, Chinese privet, eastern hemlock (Tsuga canadensis), flowering dogwood (Cornus florida), American holly, red cedar (Juniperus virginiana), and rhododendron (Rhododendron maximum). The common herbaceous species observed include Japanese honeysuckle, Christmas fern (Polystichum acrostichoides), giant cane, violets (Viola sp.) and blackberry (Rubus sp.). During the field assessments, jurisdictional waters of the U.S., including wetlands, within the Linville ESSI Project and Borrow Tract 3 boundaries, were delineated. The areas considered jurisdictional wetlands were delineated using the 1987 Corps of Engineers Wetland Delineation Manual (Environmental Laboratory, 1987). The wetlands found within the Linville Dam ESSI Project and Borrow Tract 3 boundaries were classified using the U.S. Fish and Wildlife's (USFWS) wetland classification system. Jurisdictional stream and wetland boundaries were flagged by HDRIDTA personnel and located by professional land surveyor for a jurisdictional determination from the U.S. Army Corps of Engineers (USACE) Action ID 2008-2753, dated December 15, 2008. During this assessment, four main drainage features which are made up of jurisdictional creek and wetland habitats were observed and documented within the subject properties. A description and size of each of the drainage within the ESSI project boundaries is provided below and in Table 1. TABLE 1 - JURISDICTIONAL WATERS WITHIN THE LINVILLE DAM ESSI PROJECT AREA* Drainage Name Stream Order(s) Total Stream Length linear feet Wetland Type(s) Total Wetland Area acres Linville River to Bride Fourth or above 1,279 NA NA Linville River Tributary 1 Second 333 PEM 0.02 Linville River Tributary 2 First 444 NA NA Borrow Area Tributary 1 First and Second 4,403 PFO 0.1 TOTAL 6,459 0.12 *Does not include jurisdictional areas located within the Paddy Creek areas of the Linville ESSI Project Legend PFO - Palustrine Forested PEM - Palustrine Emergent The Linville River within the Project boundaries starts at the Bridgewater Powerhouse discharge/tailrace and proceeds downstream approximately 1,279 feet to the SR 126 Bridge, where it flows outside the Project boundaries. The Linville River within the Project boundaries has an approximate width from bank to bank of 118 feet. The vegetation community along the Linville River directly below the old Bridgewater Powerhouse can best be described as a mesic mixed hardwood forest (Piedmont Subtype) (Schafale, et al., 1990). Dominant species found within the canopy include tulip poplar, red maple, and northern red oak. Some white pine is present within the upper portions of the buffer and some American sycamore is present near the river. Under-story species include immature canopy species as well as hop hornbeam (Ostrya virginiana). Shrub species present include rhododendron, blueberry species (Vaccinium sp.) and mountain laurel (Kalmia latifolia). Herb and vine species are varied and include various fescue species (Festuca sp.), flea bane (Erigeron sp.), path rush (Juncus tenuis), blackberry (Rubus argutus), and poison ivy (Toxicodendron radicans). The Linville River has two tributaries that connect to it prior to going under the SR 126 Bridge. The first drainage is located directly adjacent to and east of the Linville Dam. Two small wetland drainages that are part of this tributary are supplied by the seepage from the Linville Dam. This drainage consists of the two wetland seepage collection areas and a second order perennial stream. The jurisdictional second order stream associated with this drainage measures approximately 333 linear feet inside the Project boundary before it flows into the Linville River. The jurisdictional wetlands within the Project Boundary are associated with the seepage at the base of the dam (0.02-acres) and are made up of emergent wetland types (Cowardin et. al., 1979). The hydrology indicators found in this jurisdictional wetland consisted of standing surface water and saturated soils to the surface. In addition, drainage patterns and water-stained leaves were observed during the field wetland assessments. The second tributary is located on the downstream right bank of the Linville River below the existing powerhouse. This first-order drainage appears to be a bed and bank perennial stream approximately 2 to 3 feet in width and approximately 444 linear feet in length. This tributary is approximately 0.5 feet in depth and has moderately to steeply sloping banks with a substrate 4 consisting of sand, gravel, and silt. The area around this tributary is mostly a grass and fescue maintained lawn. At present, this drainage is buffered from the surrounding new powerhouse construction project. All tributaries are considered relatively permanent waters that are considered abutting to traditionally navigable waters. The wetlands on-site are considered abutting relatively permanent waters and therefore adjacent to traditionally navigable waters. The vegetation community along the Linville River tributaries directly below the old Bridgewater Powerhouse can best be described as a mesic mixed hardwood forest (Piedmont Subtype) (Schafale and Weakley 1990). The canopy species found in this drainage are made up of tulip poplar, red maple, American beech, sourwood (Oxydendrum arboreum), and white oak (Quercus alba). The midstory trees and shrubs included American holly, rhododendron, flowering dogwood, and Chinese privet. The herbaceous layer is made up of Japanese honeysuckle, Christmas fern, giant cane, highland doghobble (Leucothoe fontanesiana), Virginia creeper (Parthenocissus quinquefolia), galax (Galax urceolata), false nettle (Boehmeria cylindrica), sedges (Carex sp.), browntop, and cardinal flower (Lobelia cardinalis). The soil series found within these drainage areas and the adjacent uplands are Rhodhiss sandy loam, and Udorthents. Rhodhiss sandy loam is found on 25 to 45 percent slopes and is a well- drained soil found in the uplands. Permeability for this soil is moderate and shrink-swell potential is low. Seasonal high water table is below 6.0 feet. This fine-loamy, mixed, semi active, mesic Typic Hapludults is usually found in hillslopes on ridges (Knight, 2006). Udorthents is a soil that consists of areas where the natural soils have been altered by digging, grading, or filling, to the extent that individual soil types can no longer be recognized. These areas consist primarily of borrow areas; fill areas, or sanitary landfills. The characteristic of the soil material varies such that interpretive statements cannot be made without an on-site investigation (Knight, 2006). The Borrow Area 3 jurisdictional drainage intersects the Catawba River approximately 5,733 feet downstream of the second bridge over the Linville/Catawba River after the existing the Bridgewater Powerhouse (Figure 6). This drainage consists primarily of a drainage with six small first-order, two second-order and one third-order perennial streams with three jurisdictional wetlands located at the head of first order streams. The third-order stream flows directly into the Catawba River. The jurisdictional wetlands associated with this drainage within the ESSI Project Boundary are approximately 0.1 acres and is considered to be a forested wetland (Cowardin et. al., 1979). The vegetation found in the drainage and wetlands of Borrow Area 3 were the following: alder (Alnus serrulata), sweet scented joe pye weed (Eupatorium purpureum), bulrush (Scirpus cyperinus), soft rush, shallow sedge, common boneset (Eupatorium perfoliatum), Japanese honeysuckle, Christmas fern, browntop, touch-me-not (Impatiens capensis), slender woodoats (Chasmanthium laxum), threeway sedge (Dulichium arundinaceum), American holly, red maple, Chinese privet, and sensitive fern (Onoclea sensibilis). The soil series found within the drainage area and the adjacent uplands are Biltmore loamy sand Arkaqua loam and Rhodhiss sandy loam. Biltmore loamy sand is found on zero to five percent slopes and is a well-drained occasionally flooded soil with rapid permeability. This nearly level or gently sloping, mixed, mesic Typic Udipsamments is usually found in Piedmont river valleys of North Carolina (Knight, 2006). Arkaqua loam is found on zero to two percent slopes and is somewhat poorly drained with a moderate permeability rating. This nearly level fine-loamy, mixed, active mesic Fluvaquentic Dystrudepts is usually found on piedmont river valleys within the flood plains of a river (Knight, 2006). Applicant's Stated Purpose The purpose of the proposed work as described by the applicant is to improve safety and long- term stability of the existing Linville Dam as part of a nationwide effort to increase the safety of dam during potentially catastrophic earthquake events. Project Description The Linville Dam was constructed by the semi-hydraulic fill method between the years 1916 and 1919. Dams constructed utilizing these methods are typically more susceptible to liquefaction under seismic loading conditions. "Liquefaction" is a phenomenon in which the strength and stiffness of a soil is reduced by earthquake shaking or other rapid loading. Liquefaction and related phenomena have been responsible for tremendous amounts of damage in historical earthquakes around the world (University of Washington, 2007). In order to improve the safety of the existing Linville Dam and reduce the risk of a dam failure in the event of an earthquake, the applicant is proposing the construction of an approximately 100' counterweight stability berm on the downstream side of the Linville Dam. This construction will involve the placement of approximately 1 million cubic yards of fill material on the downstream side of the dam. Due to the construction of the Linville Dam ESSI Project, there will be unavoidable impacts to jurisdictional waters of the U.S. including wetlands. Within the drainages that have been noted within the Linville Dam ESSI Project boundaries, two of the four drainages will have permanent impacts to approximately 575 feet of jurisdictional streams. One of the four drainages will have permanent impacts to approximately 0.02 acres of jurisdictional wetlands. In addition, throughout the drainages, approximately 173 linear feet of jurisdictional streams will be impacted temporarily by this ESSI Project (see Table 2). TABLE 2.

The impacts will be the results of filling the river bed with material to be used in the construction of the Linville Dam ESSI berm. Both permanent and temporary impacts start at the toe of the dam/base of the existing powerhouse and ends approximately 463 linear feet downstream. The temporary impacts to the Linville River will measure approximately 173 linear feet. The temporary impacts to the river are primarily due to the construction of a proposed sediment and erosion control basins. This basin could be placed in the river channel due to the lack of area required to construct a basin in the adjacent uplands. All temporary river impacts will be returned to original contours and elevations. The permanent impacts to surface waters (290 linear feet) in the Linville River/Bridgewater tailrace is primarily due to the construction of the stability berm and the excavation of the toe of the existing dam to replace the alluvium with compacted backfill. These surface water impacts are unavoidable impacts and will be included in the proposed mitigation. Approximately 31,767 square feet (0.73 acres) of permanent impacts to the Catawba River buffer are anticipated from this Linville Dam ESSI Project. The permanent impacts to main stem buffers along the Linville River/Bridgewater tailrace is primarily due to the construction of the stability berm. Approximately 7,500 square feet of temporary impacts to the Catawba River buffer are anticipated in Borrow Area 3 as a result of the Linville Dam ESSI Project. The temporary impacts to main stem buffers along the Catawba River are primarily due to the construction of erosion and sediment control outfall structures. At present, the exact locations of the impacts are not known due to the lack of an approved erosion and sediment control plan. With regards to tributaries to the Linville River, the only tributary proposed to be impacted by the construction of the Linville ESSI stability berm is the one located directly adjacent to and east of the Linville Dam. This drainage, described previously as Tributary #1 consists of the two small wetland seepage collection areas and a second order perennial stream. There are only permanent impacts planned for this drainage. The permanent impacts to the wetlands will be due to the filling of these areas with material to be used in the construction of the Linville Dam ESSI berm. Approximately 0.02 acres of wetland habitat will be impacted due to their proximity to the dam. Due to the jurisdictional stream to be impacted continuing offsite, the flows from this drainage will be piped downstream into the tailrace of the new Bridgewater powerhouse. The amount of streambed that will be replaced by the piping of the stream is approximately 285 linear feet. The second tributary to the Linville River that was previously impacted and permitted as a temporary impact under the Bridgewater Powerhouse permit is not planned to be impacted by the construction to the Linville Dam ESSI Project. For Borrow Area 3, there is an existing road crossing over the second order perennial stream in Borrow Area 3. A temporary haul road will be constructed within the footprint of the pre- existing road crossing. The roadway will assist in the transportation of borrow material to the berm construction areas for use during the ESSI construction project. Therefore, with this crossing consisting of pre-existing impacts, no mitigation will be necessary for the temporary impacts to these jurisdictional areas (Table 2). No additional impacts to jurisdictional features are planned at this time for the Paddy Creek ESSI tract. An additional temporary impact will include the dewatering of approximately 4,846 linear feet of the Linville River prior to its confluence with Muddy Creek/Old Catawba River. In order to construct the new powerhouse and work on the hydro-electric turbines, a temporary outage of the hydro plant is necessary which result in a shutoff of water coming out of the existing Bridgewater power plant. By shutting off the water coming from the power plant, this will reduce the flows in the Linville River from 55 cfs to 1-2 cfs during the time frame of May 5, 2011 to August 3, 2011. The applicant is proposing to mitigate for permanent impacts to jurisdictional waters through the North Carolina Ecosystem Enhancement Program (EEP) in-lieu fee program. The applicant plans to mitigate for the permanent impacts to the Linville River at a 2:1 ratio and impacts to the tributary of the Linville River at a 1.5:1 ratio. The jurisdictional wetlands that will be impacted will be mitigated through EEP at a 2:1 ratio and rounded up to the nearest 0.25 acres. For the amount of mitigation need for each impact, see Table 3 below. TABLE 3.
