(S &ME) is pleased to submit this application for impacts to Waters of the U.S. in accordance with Nationwide Permit (NWP) No. 12 and the corresponding North Carolina Water Quality Certification (WQC) No. 3884. The proposed project will involve replacement of approximately 26 miles of natural gas pipeline with a new line that is compliant with current federally- mandated requirements. This PCN is being provided to the U.S. Army Corps of Engineers (USACE) for approval, and complies with all applicable conditions of NWP No. 12. Written concurrence from the North Carolina Division of Water Resources (NCDWR) is also required in part because the proposed project does not meet condition numbers 10 and 16 of WQC No. 3884, as specified below: Condition No. 10: The proposed gas line will not cross all streams within the project corridor at a near - perpendicular angle because a majority of the project will be installed within the existing Line T -01 utility easement. Because the existing utility easement does not cross all streams within the tolerance identified in the aforementioned WQC, the proposed project will also not meet this requirement. Condition No. 16: The proposed project will require a combined temporary and permanent construction easement greater than 40 -foot wide at stream and wetland crossings where the pipe will be installed. In upland areas, the work will occur within a 75 -100 foot corridor, which will be narrowed to the aforementioned 50 feet at stream /wetland crossings. In these areas, a 50 -foot wide easement is required to safely accommodate the equipment and work space necessary to install the 20 -inch pipe. Up to two other existing pipelines are present within portions of the existing maintained easement.

Safe, reliable operation of PSNC's pipeline system, along with the safety of their customers and employees, are PSNC's main goals. Like any natural gas utility, the operation and maintenance of PSNC's pipeline system is subject to extensive state and federal regulations and requirements. At the Federal level, these regulations fall under the Department of Transportation (D.O.T.), specifically — the Pipeline and Hazardous Materials Safety Administration (PHMSA). To that end, the primary purpose of the proposed project is to replace the old pipeline with a new one that is compatible with current federally- mandated safety and inspection requirements, and is capable of increasing service capabilities and reliability for PSNC's customers in western North Carolina. In general, the project route extends from an existing station near the terminus of Old Christ School Road in Arden, Buncombe County (35.45807N, - 82.50846W), south to another station located approximately one mile west of the intersection of N.C. State Highway 9 and N.C. State Highway 108, adjacent to Silver Creek Road near Mill Spring in Polk County (35.3032N, - 82.1746W). A majority of the new pipeline will be installed within the existing, maintained, 50 -foot or 75 -foot wide easement. In addition to the T -01 pipeline that will be replaced, approximately 16 miles of the subject 26 -mile easement contains either one or two additional natural gas pipelines, which must remain in service during the replacement. The location of the project corridor is depicted on the Site Vicinity Map (Figure 1), USGS Topographic Maps (Figures 2 -5) and 2010 Aerial Photographs (Figures 6 -21). Of the proposed 26 -miles to be replaced, a majority will be installed within the existing, maintained gasline easement. The proposed new gasline will only deviate from the existing easement at one location (totaling less than one mile) in order to avoid existing orchards. In these areas, work will be conducted in a "virgin" easement, largely through open fields, that will not exceed 50 feet in width. PSNC proposes to maintain a 50 -feet easement in these areas for visibility concerns, as previously noted, and for consistency with maintenance of existing pipeline easement. Aside from one stream and one wetland crossing in this area, all remaining stream and wetland impacts will occur to previously- affected features located within the existing easement. ❖ EXISTING ENVIRONMENT The project area is located in the Piedmont and Blue Ridge physiographic provinces in portions of the Upper Broad (03050105) and French Broad (06010105) River Basins. General land use in the vicinity of the project corridor consists of a mix of low density residential areas, agriculture, pasture, and forest. Portions of the project corridor are located close to areas composed of commercial and light industrial development. Photographs of typical project area conditions are included in Appendix II. The project corridor consists of the stabilized disturbance area of the existing pipeline easement, and is abutted by young successional forest, mature hardwood forest, forested rocky slopes and bluffs, agricultural fields and maintained lawn areas. S &ME, Inc. Pre - Construction Notification: NWP No. 12 /WQC 3884 September 23, 2015 Line T -01 Replacement Proiect Paae 2 General Vegetative Conditions A majority of the work will occur within the maintained, non - forested utility easement. Although vegetation within this area varied greatly, general species observed included fescue (Festuca sp.), Allegheny blackberry (Rubus allegheniensis), dogfennel (Eupotorium capillifolium), chicory (Cichorium intybus), annual ragweed (Ambrosia artemisiifolia), sericea lespedeza (Lespedezo cuneato), winged sumac (Rhus copollina), poison ivy (Toxicodendron radicans), wineberry (R. phoenicolasius), little bluestem (Schizochyrium scoparium), dandelion (Taraxacum officinale), Queen Anne's lace (Daucus carota), goldenrod (Solidago sp.), muscadine grape (Vitis rotundifolia), juncus (Juncus canadensis), and a number of other grasses and volunteer species. Woody saplings observed within less- frequently maintained portions of the utility easements included black cherry (Prunus serotina), dogwood(s) (Cornus spp.), sassafras (Sassafras albidum), tulip tree (Liriodendron tulipifera), red maple (Acer rubrum), red oak (Quercus rubra), and sugar maple (A. saccharum). Areas adjacent to the easement are typically dominated by American beech (Fagus grandifolia), red maple, southern red oak (Q. falcata), loblolly pine (Pinus toeda), shortleaf pine (P. echinata) and tulip tree in the canopy, with American holly (Ilex opaca), flowering dogwood (C. Florida), persimmon (Diospyros virginiana), Virginia pine (P. virginiona), eastern red cedar (Juniperus virginiona), great laurel (Rhododendron catowbiense) and sourwood (Oxydendrum arboreum) in the subcanopy. Shrubs include highland doghobble (Leucothoe fontanesiona) and mountain laurel (Kalmia latifolia). Dominant vines in deciduous wooded areas include crossvine (Anisostichus capreolatus), roundleaf greenbriar (Smilax rotundifolia) and posion ivy . Herbaceous vegetation includes winged sumac, Allegheny blackberry, wineberry, little bluestem, goldenrod, giant cane (Arundinaria gigantea), Christmas fern (Polystichum acrostichoides), partridge berry (Mitchella repens), cranefly orchid (Tipularia discolor), ebony spleenwort (Asplenium platyneuron), fan clubmoss (Lycopodium flabelliforme), spotted wintergreen (Chimaphila maculata) and downy rattlesnake plantain (Goodyera pubescens). In addition to the adjacent forested area identified above, the project corridor also passes through large areas of active agricultural land. A majority of these areas consisted of cultivated cropland that had been planted with pasture grasses, corn, apple, peach and nectarines. Additional areas of rough active cattle, horse or goat pasture were also observed along the route. Species located in pastureland and at the periphery of cultivated areas included fescue, Allegheny blackberry, dogfennel, crabgrass (Digitaria sanguinalis), goldenrod, American pokeberry (Phytolacca americana), partridge pea (Chamaecrista fasciculato), morning glory (Ipomoea purpurea), ragweed, little bluestem and various grasses. A variety of other land use areas were observed along the project corridor, but occupy an insignificant portion relative to the habitat types identified above. Such portions of the project corridor include residential land, active recreational land including golf courses and parks, maintained lawns, roadway easements or lightly - developed areas with typical ornamental landscape or playing surface related native and non - native vegetation. Jurisdictional Areas S &ME wetland professionals delineated Waters of the U.S. within a majority of the project corridor in March 2014 through April 2014. Additional field visits were subsequently conducted through May 2014 to delineate re- routed areas, access roads, and laydown areas. The delineation was conducted utilizing currently accepted methods for wetland determination, as set forth in the 1987 Corps of Engineers Wetlands Delineation Manual and the corresponding Eastern Mountain and Piedmont Region USACE Regional Supplement Guide, which states that under normal circumstances, an area must demonstrate the S &ME, Inc. Pre - Construction Notification: NWP No. 12 /WQC 3884 September 23, 2015 Line T -01 Replacement Proiect Paae 3 presence of 3 components to be considered jurisdictional: 1) hydrophytic vegetation, 2) hydric soils, and 3) wetland hydrology. When necessary, stream assessments were conducted in accordance with NCDWR and USACE guidelines. The boundaries of jurisdictional areas were identified in the field using conventional surveying equipment or Global Positioning System (GPS) units capable of sub -meter accuracy. The field review resulted in delineation of 55 wetland or open water areas and 79 streams within the proposed work area. Of these, 53 of the wetland areas and 67 of the streams will be affected by the project. Jurisdictional features are depicted on the Jurisdictional Impact drawings, included in Appendix IV. A Request for Preliminary Jurisdictional Determination package that included USACE Stream Assessment Sheets, NCDENR Stream Identification Sheets, and Routine Wetland Determination Data forms for each general type of wetland observed was provided to the USACE separately on July 14, 2015. Representatives of the USACE (Craig Brown) and NCDWR (Andrew Moore) visited the project site on September 15, 2015 to approve the delineation and verify the location /classification of affected features. ❖ DESCRIPTION OF THE PROPOSED WORK General Pipeline Construction Construction of the new pipeline will first involve demarcation of clearing limits, jurisdictional boundaries, and other associated workspaces, etc. In high ground areas, up to an additional 50 feet of temporary workspace (TWS) adjacent to the existing easement will be required to safely install the new pipe. At stream and wetland crossings, the TWS will be eliminated, and work will be conducted only within the existing, maintained easement. In wetland areas, efforts will be made to remove surface vegetation in a manner that minimizes disturbance of the substrate and prevents exposure of soil. If necessary, temporary equipment crossings will be installed along one side of the easement to facilitate equipment passage, cross over streams, and prevent excessive rutting and ground disturbance in the wetlands. Appropriate sediment and erosion control (S &EC) measures will be installed as clearing proceeds to prevent sedimentation of jurisdictional features. No grubbing or below - ground vegetation removal will occur within wetlands or along stream banks outside of the construction corridor. Where the pipe will be installed by conventional means (e.g. "open - trench" or "isolation "), grubbing will be limited, to the extent practicable, to the trench line. Select upland portions of the easement may require rough grading to facilitate safe passage of equipment, and to prepare a suitably -level work surface. Within wetland areas where extensive rutting or soil disturbance may occur, timber mats are planned for use to provide work and travel space for equipment. Following preparation of the work area and installation of necessary E &SC measures, the trench will be excavated along the "non- working" side of the easement. Subsurface disturbance will only be conducted within the trench line at wetlands and stream crossings. Stump removal or light grading may occur on the working side of the easement if required for safety reasons. The work will be performed from the timber mats placed along the working side of the easement. In certain areas, including wetlands and fields supporting crops, efforts will be made to segregate topsoil from the subsoil. If necessary, trench breakers (temporary barriers generally constructed of sand bags or similarly suitable material) will be installed within the trench to slow the flow of subsurface water. S &ME, Inc. Pre - Construction Notification: NWP No. 12 /WQC 3884 September 23, 2015 Line T -01 Replacement Proiect Paae 4 In general, approximately 40 -foot lengths of the 20 -inch pipe will be trucked to the site from temporary storage yards, strung along the easement and placed on skids (wooden pedestals). Specialized machines will be used to bend individual segments of pipe to fit the contours of the trench where necessary. The pipe segments will be welded together, x- rayed, the structural integrity and surface coating inspected, and then lowered into the trench. Segments of the trench may require dewatering or "padding" to prevent large rocks or other debris from coming in contact with the pipe. Permanent trench breakers will then be installed where necessary and the trench backfilled. In areas where segregation of the subsoil and topsoil is required, the topsoil will be replaced last. Affected areas will then be "cleaned up" by rough - grading and temporary seeding (if necessary), followed by final grading, permanent seeding and mulching to restore the easement as closely as possible to pre- disturbance contours and conditions. All work within wetlands and streams will be conducted in accordance with the applicable permits. Best Management Practices (BMP's) will be employed at all stream and wetland crossings to help prevent siltation or inadvertent discharges to a Waters of the U.S. Jurisdictional Impact drawings associated with each individual stream and wetland crossing are included in Appendix IV. Stream /Wetland Crossing Methods There are many factors that affect selection of an appropriate and constructible installation method for a natural gas pipeline. Typical methods of installation include HDD (horizontal directional drilling), conventional bores, and /or conventional isolation. Regulatory implications, environmental impacts, cost, constructability, and pipeline integrity are considered during the design and maintenance of pipelines and thus the selection of crossing methodology. In the western part of the state, topography and geology (the presence of subsurface rock) are major factors that often contribute to making "trenchless" installation an option that is not practicable or infeasible. The use of conventional trench construction is often the preferred method, as it allows the pipeline to be installed at a consistent 4 -5 feet depth below land surface for a far greater length when compared to trenchless installation. Maintaining a normal depth is critical to the safety and integrity of the pipeline. As the depth of cover increases, so does the difficulty in locating, exposing, and performing routine maintenance required for transmission pipelines. Less environmentally invasive installation methods, such as HDD and bores, are considered during the design process. However, estimates from leading industry contractors indicate that the use of HDD construction in areas where conventional trench construction is feasible increases the anticipated cost of each crossing by 500% to 800 %, depending on a number of site - specific factors. Location specific conditions, such as topography, physical barriers, subsurface conditions, etc. dictate how much cost savings will be achieved at any stream or wetland crossing and those factors can significantly increase the cost and risk of HDD as a crossing methodology. Additionally, the physical characteristics of the pipe, such as the bending radius on a 20" pipeline, require any bore to traverse at a minimum distance around 800 feet, which is well beyond the area of concern. Conventional Bore and HDD All named and major stream channels that will be affected by the proposed replacement project were assessed for suitability of bore or HDD pipe installation. It was determined that such methods of installation were practicable at 11 locations. In addition, impacts to a large wetland (WC19) will also be avoided by use of HDD. Factors used to determine the most appropriate method of installation included: S &ME, Inc. Pre - Construction Notification: NWP No. 12 /WQC 3884 September 23, 2015 Line T -01 Replacement Proiect Paae S • Physical limitations with respect to bending radius (flexibility) of the 20 -inch pipe • Existing subsurface geologic conditions • Existing topography and slope to accommodate acceptable entry and exit angle • Availability of suitable additional workspace necessary to construct bore pits or set up drill rig and associated equipment • Presence of existing utilities /infrastructure in relation to the new pipe • Accessibility of the site for the specialized equipment • Availability of additional land for pipe stringing, welding and pullback operations • Additional costs associated with use of "trenchless" technology given the project scale Additionally, it should be noted that use of HDD increases the risk of an inadvertent release of drilling fluid to the stream, and the amount of time required to complete the operation. Inadvertent returns are difficult to anticipate, can be difficult to locate, and can be difficult to remediate. They typically occur as a result of fractures in subsurface rock or unconsolidated materials located in the subsurface environment. While geotechnical investigations can provide a narrow window of understanding with respect to the surrounding subsurface conditions, they cannot detect all conditions. Once drilling fluid has found fractures, water columns, or unconsolidated material within which to move, there is no way to predict where surface releases may occur. Inadvertent returns are often detected visually for smaller returns near the easement; however, larger returns are typically detected as a loss of pressure in the fluid being pumped through the annulus of the drill. Fluid pressure and easement conditions are constantly monitored by trained pipeline professionals; however, dependent on site geological conditions adjacent to the annulus of the drill, high volume /high pressure fluid can be lost quickly, and oftentimes occur in areas within which it is difficult to assess and /or access for clean -up (e.g. densely forested areas outside of the easement). As previously stated, the cost associated with HDD technology is significantly more than conventional methodology due to limited specialist drilling companies, the aforementioned sub - surface conditions, and the cost of specialized equipment (e.g. drilling bits for varying conditions, and specialized pipe and pipe coatings). The likelihood of inadvertent return also adds to the cost and risk of a HHD crossing due to the resulting extended drilling duration, additional costs for remediation, and potential for discharge to sensitive areas that can occur with inadvertent returns. Conventional bore installation will be employed for several stream crossings, but was not considered a viable option for many locations. Because the new line will be installed within an existing maintained easement for the most part, the proximity to the additional PSNC pipelines precludes the safe excavation of the required bored pits. In other areas, and in general for the project overall, many of the streams crossed are incised or located at the bottom of steep, relatively narrow valleys, making excavation of the bore pit and stockpiling of the soils within the corridor difficult. As the bore pit must be excavated to a depth at which the bore can extend beneath the substrate of a stream or wetland, additional shoring of the pit would be necessary to meet safety standards. Conventional Isolation Installation Throughout the project corridor where conventional isolation construction is proposed at stream crossings, dam and pumps or flume systems will be used to divert clean water flow around the work area until the crossing is completed. Typically, crossings of minor streams (less than 10 -feet wide) can be completed within 24 -hours of initiation. For larger waterbodies or those where specialized equipment for excavations in rock are required, it may be necessary to extend this time frame. But in any event, once S &ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 6 work affecting streams or wetlands is initiated, it will be carried to completion in an expeditious manner to minimize the period of disturbance. Affected stream banks will then be restored to near pre -construction contour. Coir matting and a native riparian seed mix will be applied to restore vegetation. Typical details for a dam and pump and flume methodology for isolation of the trench excavation are included in Appendix V. Typical BMPs used in connection with conventional isolation methodology include the following: • Crossings will be executed in as minimal amount of time necessary. Where possible, 24-hour installation and restoration will be required. • Sufficient equipment to execute the crossing in an expeditious, environmentally responsible manner will be available on site prior to initiation of the crossing. • All crossings will be conducted during anticipated low flow conditions. • Local weather conditions will be monitored such that, to the extent possible, stormwater events will be avoided during and immediately following installation of the pipe. • The crossings will be monitored during installation by personnel experienced in stream and wetland crossing procedures, familiar with site conditions, and knowledgeable in North Carolina environmental regulations. The monitor shall have the authority to stop work should conditions change and additional or different measures be needed. This professional will be on-site from the initiation (preparatory stages) through to the completion (e.g. implementation of the restoration plan). • Sufficient qualified staffing will be maintained for the project duration such that compliance monitoring activities associated with pipeline installation in other locations do not take precedence over crossings. • The upstream and downstream crossing points will be sealed to isolate the crossing for pipeline installation "in the dry." Clean steel plates, sand bags, or similar measures will be inserted to temporarily dam the flow. Steel plates will be cleaned prior to use on streams using biodegradable products or heat. On both sides of the installed plates (both upstream and downstream) sandbags will additionally be placed to secure the plates, reinforce the damming of water, and provide a secondary barrier to seepage. The excavated trench will be monitored for groundwater intrusion and, if noted, excess water will be pumped to a discharge site located 50'-100' from the top of bank of the receiving stream. Discharged water from the trench will be filtered through an appropriate E&SC measure. • Where possible, the top 6-12 inches of streambed substrate will be stockpiled separately from the subgrade material and kept saturated during the installation. • Pumps shall be obtained and staged prior to executing the crossing. Back-up pumps shall be kept on-site should the primary pump(s) malfunction, or to control high flows. All pumps will have screened intakes and will be placed in secondary -containment for the duration of the installation. In the event an unforeseen weather event occurs during installation, pumps near the crossing will be monitored 24 -hours a day until normal flow conditions are present. • Pump flow rates will be monitored to ensure adequate flow is achieved such that water neither accumulates behind the upstream dam nor is discharged too rapidly on the downstream side. At the downstream discharge location, flow discharge rates shall be controlled such that scouring of the stream bed and/or banks does not occur. Efforts will be made to aerate the water prior to its downstream discharge into the receiving stream. • Removal of in -stream control devices will be conducted in such a manner as to allow a gradual re -introduction of flowing water into the channel. S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 7 • Banks will be restored in a careful manner, achieving pre -construction contours to the extent practical. A cover crop and specialized riparian seed mix will be applied for the entire length of banks disturbed by the crossing. Coir matting with appropriate shear strength will additionally be installed to anchor the seeding and the banks. • Stream crossings will be monitored for stability following construction and for the duration of the pipeline construction. Restoration will be considered complete when herbaceous vegetation reaches 80 -percent coverage. • Where HDD methodology is employed, the crossing will be monitored in the event an inadvertent return of drilling fluid occurs. All such occurrences that affect jurisdictional waters will be immediately contained using hay bales or other similar physical barrier, remediated to the extent practical, and reported to the USACE within 48 -hours of detection. Please note that in the event an inadvertent release occurs outside of the proposed construction corridor, additional coordination with land -owners, regulatory agents, contractors, etc. may be required, and cleanup will be initiated as soon as possible. All disturbed areas within wetlands or on stream banks will be seeded with a customized seed mix, for wetlands seed mix will extend 10 -feet landward of the jurisdictional boundary and for streams seed mix will extend 50 -feet landward of the top of bank. Stream banks temporarily affected by trenching or placement of equipment bridges will be stabilized with a native seed mix specifically designed for riparian areas, and will be stabilized with biodegradable coir matting. Affected wetland areas will be seeded with a native wetland seed mix; however, no heavy mulching will occur within wetlands. Please note that particular importance was placed on designing a trenchless method of construction for the Green River crossing, where the original pipeline was likely installed by conventional methods in the 1950s. However, the project engineers were unable to design either an HDD or bore at this location due to the extremely steep terrain on the east side of the river. As such, the pipe will be installed by conventional isolation methods using a staged coffer dam or aqua -barrier system such that the work can be conducted "in the dry." The height and dimensions of the proposed coffer dam will be based on results of a hydrologic analysis currently being conducted, and will be provided to the USACE/NCDWR for approval prior to construction. Additional Construction Project -wide, permanent impacts associated with placement of pipes and/or fill material will total 25 linear feet of stream and 0.02 acre of wetland associated with improvement of existing access roads. PSNC also plans to fill a small pond (0.11 acre) that was excavated by a landowner on the easement sometime after the original pipeline was installed. The pond is considered "in-line" as culverted portions of a nearby stream serve as its inlets and outlet. To conduct the work, a coffer dam will be constructed upstream of the inlet pipe, and clean streamflow pumped to a point below a second coffer dam constructed downstream of the outlet pipe. Once the clean water bypass is established, water remaining within the pond will be pumped -out through a filter bag or dewatering structure constructed in high ground, and the pond filled to original grade with clean fill material. The former inlet and outlet culverts will then be relocated and connected near the edge of the existing easement to reestablish the normal flow and circulation patterns of the stream. S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 8 ❖ PROPOSED PROJECT IMPACTS Project -wide wetland impacts are summarized in Table 1 below: Table 1: Summary of Proiect-wide Wetland Im Temporary Impacts Permanent Open Water Impacts Permanent Wetland Impacts (Fill (Fill placement) Placement and Conversion) 3.82 0.11 0.06 Total, project -wide construction of the project will result in impacts to 3.99 acres of wetlands or open waters. Of these impacts, 3.82 acres will be temporary, and 0.17 acres will be permanent. The permanent impacts will result from conversion of forested wetlands to emergent wetlands through periodic mowing. Permanent loss of Waters of the U.S. will occur through placement of fill material into the small pond previously constructed on the existing easement without PSNC's consent, and for improvement of a permanent access road. The remaining wetland impacts associated with the project are temporary in nature, and will occur as a result of trench excavation, temporary side casting of material and placement of timber mats for the equipment crossings. It should be noted that temporary workspace (TWS) has been eliminated at stream and wetland crossings. Work in wetlands and streams has generally been limited to the existing 50 -foot wide corridor throughout the project, and disturbed areas will be seeded and restored to their original grade and contour. Impacts associated with each individually -identified wetland area within the proposed project disturbance limits are identified in Appendix III and depicted on the figures in Appendix IV. The project will result in impacts to 5,578 If of jurisdictional streams. These impacts are broken down by type in Table 2 below: Table 2: Summary of Project -wide Stream Impacts Stream Impacts (if) Pipeline Construction Activities/Crossings Culvert Placement for Access Roads Temporary Permanent Permanent Temporary 5,412 0 25 141 As indicated, a majority of the impacts are associated with placement of equipment bridges and isolation crossing methods (clean water bypass via dam -and -pump or dam -and -flume) around a segment of bank that will be excavated to accommodate placement of the pipe. Twenty-five linear feet (If) of permanent impact will result from replacement of an unserviceable pipe at an existing access road, and 141 If will result from temporary culvert placement or access road improvements. Following construction, disturbed wetlands within the permanent easement will be vegetated with herbaceous cover, while those within the TWS will be seeded and allowed to return to a forested condition. Affected portions of the streams will be reconstructed to their pre -disturbance dimension and profile, and stabilized using coir matting and vegetative plantings, without use of riprap or hard armoring, S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 9 unless such material was their prior to construction. Typical stream and wetland crossings details (Figures Dl through 1137) are included in Appendix V of this submittal. ❖ AVOIDANCE AND MINIMIZATION To avoid and minimize impacts to waters of the U.S. within the project corridor, PSNC proposes to install the new gas pipeline within their existing, maintained easement to the extent practicable. Where PSNC was not able to install in existing maintained easement (the apple orchard), the proposed new easement was routed through open areas and an agricultural field for less than one mile before tying back into the existing easement. Where streams are trenched for pipe installation, impacts will be minimized by stabilizing the temporarily - affected banks with coir matting and seeding with a native riparian seed mix. Stream sedimentation impacts will be minimized through the use of the dry -ditch construction methods, such as bypass pumping though silt bags or temporary de -watering structures, or by use of dam and flumes. Wetland impacts will be minimized during construction through the use of equipment mats at crossings and trench plugs to prevent alterations to wetland hydrology. Additionally, construction equipment operating within the wetland will be limited to that equipment necessary for clearing, excavation, pipe installation and restoration activities. Wetland vegetation will be cut at ground level, leaving existing root systems in place to promote re -growth. To the extent practicable, wetland topsoil will be segregated from the underlying subsoil in areas disturbed by trenching, except in areas with standing water or saturated soils, or where no topsoil is evident. Total disturbance through streams and wetlands is limited to the existing 50 -foot easement for a majority of the route. Where a new virgin 50 -foot easement will be established, impacts are limited to one stream and one wetland. ❖ ADDITIONAL REGULATORY CONSIDERATIONS The project will comply with all applicable conditions of NWP 12 and WQC 3884, with the exception of those noted previously. The width of the TWS and the permanent easement will not exceed 50 feet in wetlands and at stream crossings. The proposed alignment makes use of existing easement to the maximum extent practicable. As mentioned, PSNC has endeavored to limit the clearing of "virgin" 50 -foot easement. Of the proposed 26 -miles to be constructed, less than one mile will be established as virgin easement. Where the new easement will be established, the route was selected to avoid work in a historic apple orchard operation. The route around the orchard will pass primarily through open areas and an agricultural field, affecting only one wetland (WD47) and one stream (SD08) that are not otherwise located in the existing easement. All stream work will be performed "in the dry' by isolating the work area through use of dam and pump - around or dam and flume systems. The selected streams outlined in Table 1 will additionally require more stringent oversight during construction. To address potential concerns regarding stabilization of the crossings, coir matting will be installed along affected banks of these streams. Following construction, stream and wetland crossings will be restored to original grade and contour. The proposed project will not result in permanent changes in pre -construction elevation contours or stream dimension, pattern or profile. Excess material will be removed to a high ground disposal area. Affected S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 10 wetland areas will be restored in accordance with the attached Restoration Plan (Appendix VII) following completion of the work. Based on our experience with similar projects involving impacts authorized under NWP No. 12, it is our understanding that pipeline construction impacts to streams and emergent wetlands will be considered temporary if these areas are restored to original pre -construction contours once construction is completed, and do not involve the permanent placement of hard armor in streams. Federally -Protected Species To comply with applicable sections of the Endangered Species Act (ESA) of 1973 (16 USC 1531-1543), S&ME initially consulted with the U.S. Fish & Wildlife Service (USFWS) and the North Carolina Natural Heritage Program (NCNHP). S&ME provided scoping packages to both agencies on January 27, 2015. The scoping packages included depictions of the route overlain on the appropriate USGS topographic maps and aerial photographs in digital format, along with a Google Earth® kmz file of the proposed alignment. The scoping packages requested that each agency review records they may have relating to rare, endangered, or threatened species, or high quality natural communities within the vicinity of the project corridor, and provide comment. The NCNHP responded with a February 10, 2015 letter and provided a list of their records relating to rare, listed species, significant natural communities or habitat areas/managed conservation lands within one mile of the project route. Of the records, those relating to federally protected species are listed below: • EO ID No. 32130: Northern long-eared bat (Myotis septentriona(is) — last observed in 2001 • EO ID No. 32144: Northern long-eared bat — last observed in 1933 • EO ID No. 17819: Mountain sweet pitcher plant (Sarracenia jonesii) — last observed in 1987 • EO ID No. 16561: White irisette (Sisyrinchium dichotomum) — last observed in 2001 With respect to significant natural communities or habitat areas/managed conservation lands, the NCNHP identified the following sites within a one -mile radius of the project route: • Cliffield Mountain/Upper Hungry River • Mud Creek/Hickory Hill Floodplain • Walnut Flats • White Oak Mountain/Tryon Peak • Buncombe County Open Space • Green River Game Land (NCWRC) • Henderson County Open Space • Carolina Mountain Land Conservancy Easement • NC Clean Water Management Trust Fund Easement • NC Ecosystem Enhancement Program Easement The NCWRC responded with a February 23, 2015, letter that did not identify federally -protected species, but did list a number of streams with significant aquatic resources and notable adjacent features that could be affected by the project: Cane Creek in Henderson County. Cane Creek contains the Creeper [NC Threatened (T)], French Broad River Crayfish [US Federal Species of Concern (FSC), NC Significantly Rare (SR)], and S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 11 Southern Blotched Chub (NC SR). It is also Hatchery Supported Trout Waters. There is Henderson County Open Space adjacent to the river, as well. • Clear Creek in Henderson County. Southern Blotched Chub (NC SR) inhabits Clear Creek. • Little Hungry River and Hungry River in Henderson County. Both of these streams contain wild Rainbow Trout and are Hatchery Supported Trout Waters. • Green River in Polk County. The Seagreen Darter (NC SR) inhabits the Green River. • Ostin Creek in Polk County. The Seagreen Darter (NC SR) and Carolina Foothills Crayfish (NC SR) inhabit Ostin Creek. Although the USFWS did not respond with written comment, Bryan Tompkins with the USFWS attended an agency pre -application meeting with S&ME and PSNC personnel on March 25, 2015, and provided the following general comments. Mr. Tompkins indicated that he considered three principal species of concern associated with the project: dwarf -flowered heartleaf, white irisette, and northern long-eared bat. He requested that surveys and counts of these plants, if any, were identified. He indicated that there was a good chance that white irisette may be present, but not in large numbers. In regard to the northern long-eared bat, Mr. Tompkins stated that he anticipated promulgation of a 4d rule exempting utility lines where clearing occurs within 100 feet of existing easement. He requested surveys on areas where significant tree clearing occurs on virgin easement, or rocky areas where portals or other suitable habitat exist. He stated that there were no records of known hibernacula along the project corridor. The NCNHP and NCWRC correspondence is included in Appendix VI. Following the agency scoping and literature review, S&ME conducted pedestrian reviews for terrestrial species along the project corridor over a period ranging from March 2015 through June 2015, primarily to accommodate blooming periods of some of the plant species. Additional, small-scale field investigations were conducted at targeted areas, as minor route changes were implemented, or further assessment was deemed necessary. To assist with the survey for gray bat (Myotis grisescens) and northern long-eared bat, S&ME contracted Environmental Solutions and Innovations Inc. (ESI), a firm experienced in conducting such assessments in connection with large-scale linear corridor projects in the eastern United States, to conduct a portal survey. Results of the pedestrian assessment and portal survey were incorporated into a July 1, 2015 report that was provided to the USFWS for review. S&ME concluded that the proposed project is unlikely to adversely affect populations of federally - protected flora and fauna listed for Polk, Henderson and Buncombe Counties. No individuals of the federally protected flora or faunal species identified for the survey above were observed during the pedestrian reconnaissance of the project corridor. Similarly, the proposed project is unlikely to adversely affect federally -protected aquatic species (spotfin chub or Appalachian elktoe). The proposed pipeline will either: 1) cross waterbodies that may be capable of providing suitable habitat for these aquatic species via bore or HDD, 2) no suitable habitat is located within the project corridor, or 3) potential affects will be minimized by dry isolation techniques. Habitat for one terrestrial faunal species, Carolina northern flying squirrel, does exist in the project area. Because of the species crepuscular nature and its use of elevated cavities and crevices during the day, a thorough pedestrian survey for the flying squirrel is not practicable. Accordingly, individuals of this species may be affected by the minimal clearing, but the abundant adjacent habitat suggests it would not be a significant affect to the species. S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 12 One terrestrial floral species, dwarf -flowered heartleaf, by association through numerous occurrences of its genus in the eastern third of the forested edges of the proposed pipeline replacement route, may also be affected. Though S&ME carried out focused and appropriately -timed survey during the appropriate bloom season, no species of dwarf -flowered heartleaf were observed. However, in areas adjacent to the active easement it is possible that a small number of unidentified dwarf -flowered heartleaf may be affected incidentally by the project. In the event that any of these species are encountered during construction, work in that area will be temporarily stopped and the USFWS will be contacted for consultation. Following USFWS review of the July 1, 2015 report, the agency responded with an August 25, 2015 letter stating that they concurred with S&ME's findings, and concluded that the requirements under section 7 of the Act are fulfilled. A copy of the August 25, 2015 USFWS letter is included in Appendix VI. Trout Moratorium Additional follow-up consultation was also conducted with Andrea Leslie of NCWRC in order to determine which streams affected by the pipeline installation are subject to the trout moratorium. Ms. Leslie reviewed a list of streams identified within the project corridor, and through integration of both existing and new on-site data collected by NCWRC biologists in September 2015, determined which would be subject to the January 1- April 15 Rainbow Trout construction moratorium, as indicated in the table below: Table 3: Streams Subject to Rainbow Trout Moratorium "i .-I `ii_ e SC07 : s Unnamed Tributary to Harm Creek SC09/SC09A Hungry River SC10 Unnamed Tributary to Hungry River SC11 Unnamed Tributary to Hungry River SC12 Unnamed Tributary to Hungry River SC14 — Existing Crossing at Access Road Unnamed Tributary to Hungry River SC15 Unnamed Tributary to Hungry River SD01/SD01A Little Hungry River None of the on-site streams are subject to the moratorium associated with brown or brook trout (beginning October 15). A copy of this PCN will be provided to the NCWRC for any additional comment or input. Historic and Cultural Resources S&ME submitted an agency scoping letter to the North Carolina State Historic Preservation Office (SHPO) on January 27, 2015. The SHPO responded in a March 23, 2015 letter recommending a comprehensive survey of the project corridor be conducted by an experienced archaeologist. Accordingly, S&ME archaeologists conducted an archaeological survey of the project corridor intermittently from April 6 through June 4, 2015. As a result of the investigations, no previously recorded archaeological sites were re -located, and 15 new archaeological sites and isolated finds were identified. The 15 archaeological sites were recommended to be ineligible for inclusion in the National Register of Historic Places (NRNP). Results of the investigation were presented to SHPO in a June 2015 report. S&ME concluded that the S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 13 archaeological sites and isolated finds are ineligible for the NRHP, that the project area does not contain significant archaeological resources, and no further archaeological investigations were warranted. SHPO responded with a July 20, 2015 letter stating that they had reviewed the report and concurred with S&ME's findings that the project should not affect archaeological resources. Copies of SHPO letters are included in Appendix VI. Sediment and Erosion Control A separate Erosion and Sedimentation Control (E&SC) Plan will be prepared and submitted to the North Carolina Division of Environment and Natural Resources — Division of Land Resources (NCDENR-DLR). The E&SC plan will specify the appropriate E&SC and Best Management Practices (BMPs) outlined in the most recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual." Through early cooperation and planning with NCDENR-DLR staff, PSNC and S&ME are currently designing an E&SC plan to employ numerous measures that meet or exceed specifications governing the proper design, installation, operation, and maintenance of S&EC measures and BMPs. The E&SC plan will be submitted to NCDENR — DLR, and approval received prior to initiation of construction. Construction supervisors directing crews responsible for installation and maintenance of erosion control measures will be experienced in North Carolina S&EC measures, pipeline construction as it relates to E&SC measures and BMPs, and will be responsible for completing the required NCDENR — DWR self - inspection forms. These forms will be completed for disturbed areas at least once per 7 calendar days and within 24 hours of a rainfall event greater than 0.5 inch per 24-hour period. Multiple rain gauges will be located along the construction corridor and monitored daily. Per current NCDENR guidance, areas disturbed during clearing or construction operations will be temporarily or permanently seeded and mulched when construction activities will not occur within a period of 7 or 14 days on a particular section of the pipeline. Waterbars will be spaced at appropriate intervals based on existing slope. Sediment tubes (Filtrexx FilterSoxx, or Engineer approved equivalent) will be spaced at similar intervals in areas where construction occurs within, or partially within, existing natural gas easements. Due to the presence of 1 or more existing below -ground natural gas pipelines, mass grading above the existing lines is not feasible, so the denuded portion of these areas should be limited to the pipeline trench and areas immediately adjacent to it. Water bars and sediment tubes will be installed at the base of slopes up -gradient of streams or wetlands. Silt fence will be installed along the top -of -bank at streams and at wetland boundaries maintaining a 10 - foot buffer between the silt fence and the jurisdictional feature. Silt fence will be installed such that it, in combination with other measures approaching streams and wetlands, dissipates and directs flow away from the crossing. Additionally, sediment tubes or wattles will be utilized at stream and wetland crossings to provide a sediment barrier that can be temporarily removed to allow equipment access to bridges or timber mats. Dewatering of trenches within streams and wetlands will be discharged through a filter bag or other temporary S&EC control structure. Construction activities within wetlands will be conducted from timber mats. Where clearing operations occur in wetlands, low ground pressure equipment will be used in areas beyond those protected by timber mats. Construction activities within streams will be conducted "in the dry" through the use of S&ME, Inc. Pre -Construction Notification: NWP No. 12/WQC 3884 September 23, 2015 Line T-01 Replacement Project Page 14 either flumes or a pump -around bypass. Temporary spoil piles associated with stream crossings will be set back a minimum of 10 feet from the top of bank and protected with a row of silt fence on the down - gradient portions of the stockpile. Temporary bridges will be utilized at stream crossings so that equipment can safely cross the stream. Bridges will be wrapped in geotextile fabric and have plywood sideboards to prevent sediment from entering the stream being crossed. Mitigation A majority of the proposed project impacts are temporary. Streams and wetlands affected by installation of the pipe will be restored to their original grade and contour upon completion of the work. However, approximately 25 linear feet of stream and 0.02 acre of wetland will be permanently affected by fill or culvert placement for improvement of existing access roads. In addition, approximately 0.04 acre of forested wetland (WD47) will be converted to herbaceous wetlands. The wetland is located within the new easement that has been re-routed to avoid an apple orchard, and represents the only such conversion that will occur. Permanent impacts associated with filling the pond (0.11 acre) will not require mitigation, per our September 15, 2015 site visit with the USACE. As such, project -wide "mitigatable" impacts are limited to 0.4 acre of wetlands and 25 If of stream. These amounts are below the 0.10 -acre and 125 -If thresholds, respectively, where compensatory mitigation is required. Accordingly, we do not anticipate that purchase of mitigation credit through a private bank or in -lieu fee program will be required. General mitigation has been provided by avoidance and minimization procedures implemented during the design phase of the proposed project. Impacts to streams and wetlands within the project corridor will be minimized by: 1) extensive installation of the pipe within the existing, maintained easement 2) reduction of impacts within new virgin easement through avoidance; 3) Use of trenchless crossing methodology where feasible; and 4) by eliminating temporary workspace through wetlands and streams. SEPA Compliance The proposed project does not involve use of public monies. A small portion of the project will take place on state-owned land (Green River Gameland), but does not meet the minimum criteria established by the State Environmental Policy Act, and as such, does not require preparation of an environmental document.

Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: A majority of the work will take place within an existing, maintained natural gas pipeline easement. General land use in the vicinity of the project corridor consists of a mix of low density residential areas, agriculture, pasture, and forest. Portions of the project corridor are located close to areas composed of commercial and light industrial development. 3b. List the total estimated acreage of all existing wetlands on the property: Over four acres of wetlands/open waters are located within the project area. 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 6,245 LF of perennial and intermittent streams are located within the project area. 3d. Explain the purpose of the proposed project: The primary purpose of the proposed project is to replace an aging segment of 8 -inch diameter pipeline with a new 20 - inch diameter pipeline that is compatible with current federally -mandated safety and inspection requirements, and is capable of increasing service capabilities and reliability for PSNC's customers in western North Carolina. 3e. Describe the overall project in detail, including the type of equipment to be used: Construction of the new pipeline will first involve demarcation of clearing limits, jurisdictional boundaries, and other associated workspaces etc. In high ground areas, up to an additional 50 feet of temporary workspace (TWS) adjacent to the existing easement will be required to safely install the new pipe. At stream and wetland crossings, the TWS will be eliminated, and work will be conducted only within the existing, maintained easement. Appropriate sediment and erosion control (S&EC) measures will be installed as clearing proceeds to prevent sedimentation of jurisdictional features. No grubbing or below -ground vegetation removal will occur within wetlands or along stream banks outside of the construction corridor. Where the pipe will be installed by conventional means (e.g. "open -trench" or "isolation"), grubbing will be limited, to the extent practicable, to the trench line. Select upland portions of the easement may require rough grading to facilitate safe passage of equipment, and to prepare a suitably -level work surface. Within wetland areas where extensive rutting or soil disturbance may occur, timber mats are planned for use to provide work and travel space for equipment. Following preparation of the work area and installation of necessary S&EC measures, the trench will be excavated along the "non -working" side of the easement. Subsurface disturbance will only be conducted within the trench line at wetlands and stream crossings. Stump removal or light grading may occur on the working side of the easement if required for safety reasons. The work will be performed from the timber mats placed along the working side of the easement. In certain areas, including wetlands and fields supporting crops, efforts will be made to segregate topsoil from the subsoil. If necessary, trench breakers (temporary barriers generally constructed of sand bags or similarly suitable material) will be installed within the trench to slow the flow of subsurface water. In general, approximately 40 -foot lengths of the 20 -inch pipe will then be trucked to the site from temporary storage yards, strung along the easement and placed on skids (wooden pedestals). Specialized machines will be used to bend individual segments of pipe to fit the contours of the trench where necessary. The pipe segments will be welded together, x-rayed, and inspected coating and structural integrity, and then lowered into the trench. Segments of the trench may require dewatering or "padding" to prevent large rocks or other debris from coming in contact with the pipe. Permanent trench breakers will then be installed where necessary and the trench backfilled. In areas where segregation of the subsoil and topsoil is required, the topsoil will be replaced last. Affected areas will then be "cleaned up" by rough -grading and temporary seeding (if necessary), followed by final grading, permanent seeding and mulching to restore the easement as closely as possible to pre -disturbance contours and conditions.

A PRE -FABRICATED BRIDGE OR FLATBED RAILCAR , FLEXI-FLOAT OR FLUMED VEHICLE CROSSING MAY BE SUBSTITUTED FOR THE TEMPORARY BRIDGE. INSTALL THE BRIDGE IN A MANNER THAT WILL MINIMIZE SEDIMENT ENTERING THE WATER. STRINGERS MUST BE DESIGNED TO SUPPORT THE LOADS EXPECTED ON THE BRIDGE. CURBS AT LEAST 6 IN. HIGH MUST BE INSTALLED ALONG THE EDGE OF THE DECK TO CONTAIN SEDIMENT AND DEBRIS ON THE BRIDGE. FASTENERS CONNECTING COMPONENTS MUST BE STRONG ENOUGH TO HOLD THEM IN POSITION DURING THE LIFE OF THE BRIDGE. CRIBS MAY BE FILLED WITH ROCK OR COBBLE, OR MAY BE SOLID TIMBER ROTATED 90' IN ALTERNATIVE LAYERS. RIP -RAP EROSION PROTECTION IS TO BE PLACED AROUND THE CRIBS AND ON ANY FILL SLOPES PROJECTING INTO THE WATER. ROAD APPROACHES LEADING TO THE BRIDGE MUST BE RAISED AND STABLE SO EQUIPMENT LOADS ARE SUPPORTED A SUFFICIENT DISTANCE BACK FROM THE WATER TO REDUCE SEDIMENT AND DEBRIS ENTERING THE STREAM FROM EQUIPMENT TRACKS. DO NOT USE SOIL TO CONSTRUCT OR STABILIZE EQUIPMENT BRIDGES. IF CUTS ARE NEEDED TO OBTAIN A SATISFACTORY GRADE, THEY ARE TO BE DUG WITH SIDE DITCHES AND STABLE SLOPES. EROSION AND SEDIMENT CONTROL MEASURES ARE TO BE INSTALLED TO KEEP SEDIMENT ON LAND (E.G., SILT FENCING, FILTER CLOTH, RIP -RAP, SEED AND MULCH, ETC.).

The NCNHP database shows several records for rare species, a natural area, and conservation/managed areas within the proposed project area. The proposed project area was analyzed by using the Geographic Inforamation System (GIS) line data submitted with your request, buffered by 100 feet. The project area was then intersected with the NCNHP database via the Natural Heritage Data Explorer(https://ncnhde.natureserve.or) to provide the attached tables that show natural heritage resources documented within the project area and also within a one -mile radius of the project area. The locations of the natural areas and conservation/managed areas within and near the project area may be viewed by accessing the Natural Heritage Data Explorer online map viewer, or by downloading and using Geographic Information System (GIS) data; both options are available from the NCNHP Data Services webpage (www.ncnhp.org). Please note that occurrences of rare species documented within one mile of the proposed project area increase the likelihood that these species may be present within the project area if suitable habitat exists. The use of Natural Heritage Program data should not be substituted for actual field surveys if needed, particularly if the project area contains documented occurrences of rare species or contains suitable habitat for rare species. If rare species are found during field surveys, the NCNHP would appreciate receiving this information so that we may update our database. Thank you for your inquiry, and please feel free to contact me at Allison.Weakley@ncdenr.gov or 919- 707-8629 if you have questions or need additional information.

In that meeting Mr. Tompkins informed you of the potential impacts that the project could have on federally listed species. He requested that surveys for federally listed species be conducted within suitable habitat areas along the pipeline corridor. On July 6, 2015, we received a copy of your Protected Species Assessment for the subject project. We have reviewed the information you presented and are providing the following comments in accordance with the provisions of the National Environmental Policy Act (42 U.S.C.§4321 et seq.) (NEPA); the Fish and Wildlife Coordination Act, as amended (16 U.S.C. 661-667e), and section 7 of the Endangered Species Act of 1973, as amended (16 U.S.C. 1531-1543) (Act). According to the information that you presented, PSNC is proposing to replace about 26 -miles of 8 -inch natural gas pipeline with a 16 -inch pipeline. The pipeline replacement will extend from Arden, North Carolina to Mill Spring, North Carolina. A majority of the pipeline replacement will occur within the existing, maintained right-of-way. Installation of the new pipeline will deviate from the existing corridor at three separate locations totaling just over mile in length. The areas adjacent to the existing pipeline corridor consists of wooded areas, open fields, agricultural areas, and commercial/residential/light industrial development. The pipeline replacement will require numerous stream and wetland crossings and PSNC will be applying for a Nationwide Permit from the Corps to authorize the impacts. Federally Listed Species — According to the information provided, S&ME personnel conducted surveys within areas of potentially suitable habitat for federally listed species known to occur in Buncombe, Henderson, and Polk Counties. Surveys and assessments were conducted over a period ranging from March 2015 to June 2015. Though your letter indicates the proposed project is "not likely to adversely affect" Appalchian elktoe (Alasmidonta raveneliana), spruce fir moss spider (Microhexura montivaga) Carolina northern flying squirrel (Glaucomys sabrinus coloratus) and gray bat (Myotis grisescens), all of which are currently listed as endangered species, we believe these species will be unaffected by the proposed project and our concurrence is not necessary. Surveys were conducted for the federally threatened swamp pink (Helonias bullata), dwarf -flowered heartleaf (Hexastylis naniflora), small -whorled pogonia (Isotria medeloides), and Virginia spiraea (Spiraea virginiana), as well as the federally endangered, rock gnome lichen (Gymnoderma lineare), bunched arrowhead (Sagittaria fasciculata), mountain sweet pitcher plant (Sarracenia rubra spp. Jonesii), and white irisette (Sisyrinchium dichotomum). Although habitat was found to be present for these species, no individuals were found to occur within the project area. You determined that the project "may affect, but is not likely to adversely affect" these species. Habitat for the federally threatened northern long-eared bat (Myotis septentrianalis) was also found to be present within the project area. Surveys for potential hibernacula (i.e. caves) for this species were conducted. Several small openings were found but after further survey, it was determined that none of the openings were suitable hibernacula and no evidence of past use was observed. Though the project will require some tree clearing, tree clearing activities will be conducted outside of the recommended maternity roosting moratorium of May 15 -August 15 except for some areas that will be cleared that are within 100 -feet of the existing pipeline corridor. For these reasons a "may affect, not likely to adversely affect" determination was also made for northern long-eared bat. We concur with your "may affect, not likely to adversely affect" determinations for the above listed species. Further, we believe that a "no effect" determination is warranted for all other federally listed species known to occur in Buncombe, Henderson, and Polk counties. Therefore, we believe the requirements under section 7 of the Act are fulfilled. However, obligations under section 7 of the Act must be reconsidered if: (1) new information reveals impacts of this identified action that may affect listed species or critical habitat in a manner not previously considered, (2) this action is subsequently modified in a manner that was not considered in this review, or (3) a new species is listed or critical habitat is determined that may be affected by the identified action. Project Recommendations - We are concerned about the introduction and spread of invasive exotic species in association with the proposed project. Without active management, including 2 the revegetation of disturbed areas with native species, project corridors will likely be sources of (and corridors for) the movement of invasive exotic plant species. Exotic species are a major contributor to species depletion and extinction, second only to habitat loss. Exotics are a factor contributing to the endangered or threatened status of more than 40 percent of the animals and plants on the Federal List of Endangered and Threatened Wildlife and Plants.a It is estimated that at least 4,000 exotic plant species and 2,300 exotic animal species are now established in the United States, costing more than $130 billion a year to control.b Additionally, the U.S. Government has many programs and laws in place to combat invasive species (see www.invasivespecies.gov). Specifically, Section 2(a)(3) of Executive Order 13112 - Invasive Species (February 3, 1999) directs federal agencies to "not authorize, fund, or carry out actions that it believes are likely to cause or promote the introduction or spread of invasive species in the United States or elsewhere." Despite their short-term erosion -control benefits, many exotic species used in soil stabilization seed mixes are persistent once they are established, thereby preventing the reestablishment of native vegetation. Many of these exotic plants are also aggressive invaders of nearby natural areas, where they are capable of displacing already -established native species. Therefore, we strongly recommend that only species native to the natural communities within the project area be used in association with all aspects of this project. We also recommend that seeds for native plants that are beneficial to pollinators be included in the seed mixes. We can provide seed list/mixes that accomplish both soil stabilization and benefits to pollinators upon request. We appreciate the opportunity to provide these comments. If we can be of assistance or if you have any questions, please contact Mr. Bryan Tompkins of our staff at 828/258-3939, Ext. 240.

We also attended a scoping meeting in Swannanoa on March 25, 2015. We offer the following additional comments regarding rare and listed species and their habitats: 1. Cane Creek in Henderson County. As mentioned in our 2/23/2015 letter, Cane Creek contains the Creeper [NC Threatened (T)], French Broad River Crayfish [US Federal Species of Concern (FSC), NC Significantly Rare (SR)], and Southern Blotched Chub (NC SR). In addition, it is habitat for the Eastern Hellbender (US FSC, NC Special Concern). 2. We recommend avoiding direct disturbance to rock outcrops, a priority habitat named in the North Carolina Wildlife Action Plan, as well as the soils in the vicinity of these outcrops. Protection of canopy cover/shading of rock outcrops will help conserve amphibian priority species like green salamander. Removal of canopy/shading of rock outcrops will conserve priority reptile species. Thank you for the opportunity to review and comment on this project.

You requested records relating to rare, endangered, or threatened species, protected/managed lands, conservation easements, or high quality natural areas in the vicinity of the project corridor and recommendations and comments in the interests of NCWRC. Our comments are offered for your consideration under provisions of the Clean Water Act of 1977 (33 U.S.C. 466 et. seq.) and Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d). PSNC intends to replace 26 miles of gas pipeline in or adjacent to existing easements. The line crosses multiple streams in Buncombe, Henderson, and Polk Counties in the French Broad and Broad River basins. It crosses a number of streams with significant aquatic resources and notable adjacent features, including the following: 1. Cane Creek in Henderson County. Cane Creek contains the Creeper [NC Threatened (T)], French Broad River Crayfish [US Federal Species of Concern (FSC), NC Significantly Rare (SR)], and Southern Blotched Chub (NC SR). It is also Hatchery Supported Trout Waters. There is Henderson County Open Space adjacent to the river, as well. 2. Clear Creek in Henderson County. Southern Blotched Chub (NC SR) is found in Clear Creek. 3. Little Hungry River and Hungry River in Henderson County. Both of these streams contain wild Rainbow Trout and are Hatchery Supported Trout Waters. 4. Green River in Polk County. The Seagreen Darter (NC SR) is found in the Green River. 5. Ostin Creek in Polk County. The Seagreen Darter (NC SR) and Carolina Foothills Crayfish (NC SR) are found in Ostin Creek. Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center • Raleigh, NC 27699-1721 Telephone: (919) 707-0220 • Fax: (919) 707-0028 PSNC Line T01 Pipeline Replacement Page 2 February 23, 2015 Buncombe, Henderson, Polk Counties Line T-01 crosses through the Cliffield Mountain/Little Hungry Natural Area, rated Moderate by the NC Natural Heritage Program. We have the following general recommendations: 1. Wetlands and streams within the site boundaries should be identified through on-site surveys prior to any land disturbing activities. If wetlands and/or streams will be impacted by construction activities, then the project should be coordinated with the U.S. Army Corps of Engineers and the N.C. Division of Water Resources. 2. Avoid or minimize impacts to wetlands during construction. In addition to providing wildlife habitat, wetland areas perform important functions of flood control and water quality protection. Temporarily disturbed wetland areas should be returned to original soils and contours, and reseeded with annual small grains appropriate for the season (e.g. oats, millet, rye, or wheat) and should be allowed to revert to natural wetland vegetation. 3. Avoid or minimize stream crossings. Where the line does cross streams, the crossings should be near perpendicular (75to 105) to stream flow. Disturbed stream banks and wetlands should be restored to original contours and re -vegetated with native plant species. 4. The directional bore (installation of utilities beneath the riverbed, avoiding impacts to the stream and buffer) stream crossing method should be used for utility crossings wherever practicable. The open cut stream crossing method should be used only when water level is low and stream flow is minimal. 5. Where new pipeline crosses streams containing Rainbow Trout, avoid in -stream work during the trout spawning period of January 1 to April 15. 6. Avoid equipment maintenance in the immediate vicinity of streams, make stream crossings as narrow as possible, minimize stream bank disturbance, avoid spraying of herbicides, and cut woody vegetation so that stumps can resprout. 7. Sediment and erosion controls measures should be installed prior to any land clearing or construction. These measures should be routinely inspected and properly maintained. Excessive silt and sediment loads can have numerous detrimental effects on aquatic resources including destruction of spawning habitat, suffocation of eggs, and clogging of gills of aquatic species. 8. If any right -of way vegetation maintenance work is performed a part of this replacement project, we recommend that it generally be avoided between April 1 and October 1 to minimize impacts to ground nesting birds. 9. Where feasible, work within the existing easement to minimize impacts to terrestrial wildlife habitat. Avoid the removal of large trees at the edges of easement corridors. Use woody debris and logs from any corridor clearing to establish brush piles and downed logs adjacent to the cleared right-of-way to improve habitat for wildlife. 10. Re -seed all disturbed areas with seed mixtures that are beneficial to wildlife; avoid fescue based mixtures because fescue is invasive and provides little benefit to wildlife. Native, annual small grains appropriate for the season are preferred and recommended. Allowing the corridor area to re -vegetate into a brush/scrub habitat would maximize benefits to wildlife. For areas adjacent to residential areas, a native shrub/grass option may be beneficial.

The report meets our Guidelines and those of the Secretary of the Interior. During the course of the survey, fifteen archaeological sites were located within the project area. For purposes of compliance with Section 106 of the National Historic Preservation Act, we concur that archaeological sites 31HN296--31HN303 and 31PL73-31PL79 are not eligible for listing in the National Register of Historic Places. These sites do not retain sufficient subsurface integrity or artifact density to yield information important to history or prehistory. S&ME has recommended that no further archaeological investigation be conducted in connection with this project. We concur with this recommendation since the project will not involve significant archaeological resources.

As part of mitigation for unavoidable impacts, the following plan shall be implemented to restore temporarily -affected wetlands and streams. This plan entails restoration of temporarily -disturbed areas to their original contours and conditions to the degree practicable upon project completion. No fills or spoils of any kind will be permanently placed within wetlands or along the stream banks. Further, disturbed wetland areas and streambanks will be permanently stabilized with a native vegetative cover. The measures outlined below will be specified in the contract documents prepared for construction of the proposed project. Proposed restoration activities will include the removal of placed fill material and restoration of original pre -disturbance contours. Excavated material shall be returned to the trench to the extent possible, and remaining material relocated and retained on an upland site. Excavated topsoil will be stockpiled separately, kept viable, and then replaced uniformly over the area of excavation from which it was removed. The native seed mix identified in Table 1 below will be utilized within temporarily -disturbed streambanks and riparian areas (trout buffers).
