(S&ME) hereby submits 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 installation of approximately 2.85 miles of natural gas distribution pipeline. This Pre -Construction Notification (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. In support of this application, please find enclosed the following: ® Figures: Site Vicinity Exhibit (Figure 1) and the appropriate N.C. USGS Topographic Quad Sheets (Figures 2-4) ♦ Appendix I: Completed PCN and Authorization to Act as Agent ♦ Appendix II: Site Photographs ♦ Appendix III: Impact Tables ♦ Appendix IV: Impact Drawings (Figures 1 through 10) ♦ Appendix V: Typical Stream and Wetland Crossing Details ♦ Appendix VI: Agency Scoping Responses ♦ Appendix VII: Restoration Plan and Buffer Mitigation Availability Notice Although PNG tentatively plans to install the pipe by bore at stream/wetland crossings, this PCN is being submitted because 0.012 acre of forested wetland will be converted to herbaceous wetland, and to account for the potential that bore installation is found to be impracticable due to field conditions at any of the crossings. S&ME, Inc. 19751 Southern Pine Boulevard I Charlotte, NC 28273 1 p 704.523.4726 1 f 704.525.3953 1 www.smeinc.com Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 Written concurrence from the North Carolina Division of Water Resources (NCDWR) is also required because the proposed project will not cross all stream channels at a near perpendicular angle. ❖ General Project Information PNG is planning to install a new 2.85 -mile segment of natural gas pipeline in order to provide natural gas service and improve system strength near the Town of Gibsonville (Guilford County) and the City of Burlington (Alamance County), North Carolina. The approximate center of the project is located at 36.060619° N, -79.552300° W. The new distribution line will originate at a station site on the south side of Konica Drive near the Zink Imaging facility in Guilford County (36.061601° N, -79.577639° W). The new line will then parallel an existing PNG distribution line located in NC Department of Transportation (NCDOT) easement east to NC Highway 61. The new gasline will then cross beneath NC Highway 61 South and parallel an existing waterline easement and then the southern edge of the Intestate 85 easement for approximately 1.5 miles. The remainder of the new line will pass south of an existing NCDOT rest area before terminating at Charlie Ingle Lane in Alamance County (36.062127° N, -79.530311° W). Portions of the new gasline will parallel the aforementioned easements, while other portions will be constructed in a new 10 -foot wide, greenfield easement, with 15 feet of additional temporary work space planned to accommodate construction. The general project location is depicted on the Site Vicinity Exhibit (Figure 1). The project vicinity consists of a mixture of undeveloped wooded areas, commercial/residential/industrial development adjacent to existing roadways. The location of the project corridor is depicted in greater detail on the appropriate U.S. Geological Survey (USGS) topographic map exhibits (Figures 2-4). Typical conditions within the project corridor include mature hardwood and pine forest, mid -and young successional forest, pastureland, and stabilized disturbance areas associated with existing road rights-of- way or maintained lawn. Several of the wooded areas consisted of shrubby edge habitat dominated by typical aggressive edge colonizing plants under intact forest canopy of varying habitat types and in varying successional stages. Vegetation types within these areas consist of intergrades of sunlight - influenced edge characteristics, and often a mix of opportunistic, sub -mature woody vegetation. Species observed within wooded portions of the project corridor included sweetgum (Liquidambar styraciflua), red maple (Acer rubrum), pignut hickory (Carya glabra), white oak (Quercus alba), tulip tree (Liriodendron tulipifera), American beech (Fagus grandifolia), black cherry (Prunus serotina), southern red oak (Q. falcata), sourwood (Oxydendrum arboreum), shortleaf pine (Pinus echinata) and loblolly pine (P. taeda) in the canopy. American holly (Ilex opaca), flowering dogwood (Cornus Florida), eastern red cedar (Juniperus virginiana) and Virginia pine (P. virginiana) were present in the subcanopy. Shrubs included Chinese privet (Ligustrum sinense) and autumn olive (Elaeagnus umbellata). Dominant vines in deciduous wooded areas include crossvine (Anisostichus capreolatus), roundleaf greenbriar (Smilax rotundifolia), and porion ivy (Toxicodendron radicans). Although such areas varied greatly, vegetation within maintained, non -forested areas included fescue (Festuca sp.), dogfennel (Eupatorium capillifolium), goldenrod (Solidago sp.), Allegheny blackberry (Rubus allegheniensis), Queen Anne's lace (Daucus carota), ragweed (Ambrosia artemisiifolia), sericea lespedeza (Lespedeza cuneata), winged sumac (Rhus copallina), wineberry (R. phoenicolasius), little bluestem (Schizachyrium scoparium), dandelion (Taraxacum officinale), American pokeberry (Phytolacca americana), partridge pea (Chomaecrista fasciculata), morning glory (Ipomoea purpurea), muscadine (Vitis rotundifolia), poison ivy, and a number of other grasses and volunteer species. S&ME, Inc. Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 Review of the Gibsonville, NC USGS Topographic Maps (Figure 2) indicated that Back Creek and a number of unnamed tributaries to Alamance Creek cross the proposed easement. According to the Guilford and Alamance County Soil Surveys, predominant soil types mapped within the project area include Chewacla sandy loam, Coronaca clay loam, Enon soils, Helena sandy loam, Lloyd clay loam, Madison sandy loam, Mecklenburg sandy clay loam, Wilkes soils, and Worsham sandy loam. ❖ Description of the Proposed Work The project includes the installation of approximately 15,080 linear feet of 8 -inch diameter plastic pipeline. PNG is acquiring a permanent cross -county easement that is 10 feet wide and a roadside disturbance width of approximately 10 feet along Konica Drive and NC Highway 61 South. The majority of the temporary workspace associated with the 8 -inch diameter pipeline will be 15 feet wide with larger areas near some existing billboards. Construction of the project may include clearing and grubbing within the 25 -foot wide workspace, as well as excavating a trench to install the pipeline. Construction of the new pipeline will first involve demarcation of clearing limits, jurisdictional boundaries, and other associated workspaces, etc. The new pipe will be installed in a new 10 -foot wide easement. In general, an additional 15 feet of temporary workspace adjacent to the existing easement will be required to safely install the new pipe. At the wetland crossing, 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 the wetland 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 the wetland area where extensive rutting or soil disturbance may occur, timber mats will be placed 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 the wetland, 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. Lengths of the 8 -inch pipe will be trucked to the site from temporary storage yards, strung along the easement and placed on skids (wooden pedestals). The pipe segments will be heat -welded together, inspected, and then lowered into the trench. 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.

Best Management Practices (BMPs) will be employed at all stream and wetland crossings to help prevent siltation or inadvertent discharges to a Waters of the U.S. Jurisdictional Areas On September 7, 2016, S&ME visited the project area to delineate jurisdictional features located therein. S&ME followed the procedures set forth in the 1987 USACE Wetlands Delineation Manual and the Eastern Mountains and Piedmont Region Supplemental Guidance. Field conditions were documented using USACE Routine Wetland Determination Data Forms, as appropriate. The field review also included identification of tributaries (streams or jurisdictional ditches) within the project area. Drainage features identified during the field review were assessed to determine the jurisdictional status of the tributary. Drainage features were classified as either non jurisdictional or jurisdictional. S&ME used the NCDWR Stream Classification Form to document characteristics of identified drainage features on the day of the assessment. During the site visit, the boundaries of regulated surface waters were demarcated using sequentially -numbered flagging. Photographs of the subject features are included in Appendix H. A Request for Pre -JD was submitted to the USACE on October 6, 2016. Streams, Wetlands, and Riparian Buffers Multiple jurisdictional streams (S2 through S7) were identified during the site visit. Two of the streams (S7 and S3) are classified as perennial, while the remainder are intermittent. In addition, two wetland areas (WB and WC) were also observed. WB is a headwater forest wetland that abuts S5, and WC is a basin wetland located within a linear depression that is permanently ponded by continuous discharge from a municipal water line.

Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 temporary equipment crossing. A portion of S4 flows through an area that has been identified as a potential temporary laydown area, but will not likely be affected. This portion has also been included as temporary impact in the event and additional equipment crossing through this area is required. The wetland impact will result from installation of the new pipe and permanent conversion (forested wetlands to herbaceous wetlands). Five of the seven proposed crossings will affect streams subject to Jordan Lake Watershed riparian buffer rules administered by NCDWR (because the project crosses municipal jurisdictions). The riparian buffer extends 50 feet from the top of bank, and consists of two zones: Zone 1 extends 30 feet landward of the top -of -bank, and Zone 2 extends 20 feet landward from the outside edge of Zone 1. To determine the project's applicability to the buffer rules, S&ME reviewed the project corridor with NCDWR (Sue Homewood) on November 1, 2016. A summary of impacts to riparian buffers is provided in Table 2. Table 2: Summary of Buffer Impacts - Stream Crossin ID Stream ID Zone 1 Wacts (sf) �i Zone 2 Impacts (sf) Perpendicular ? Crossing. Permanent Conversion Temporary Disturbance Permanent Conversion Temporary Disturbance Details of the proposed impacts are included in Appendix M. Drawings depicting each proposed stream and wetland crossing are included in Appendix IV, and typical cross-sectional views are included in Appendix V. The project will not result in permanent stream impacts, or a loss of Waters of the U.S. Following construction, the temporarily affected jurisdictional area will be returned to their pre - construction grade and contour, seeded, and stabilized. No permanent fill placement or aboveground station construction is required. •'• Protected Species To comply with applicable sections of the Endangered Species Act (ESA) of 1973 (16 USC 1531-1543), S&ME first reviewed the North Carolina Natural Heritage Program (NCNHP) database and the U.S. Fish and Wildlife Service (USFWS) lists to identify occurrences of federally protected species that may be documented in Guilford and Alamance Counties. The NCNHP provided a September 6, 2016 report that indicated they had no records for rare species, important natural communities, natural areas, or conservation/managed areas within the project area boundary, and there are no records of federally protected species documented within one mile of the project area. S&ME, Inc. Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 Federally protected species listed for Guilford County are summarized in Table 3. There are no federally protected species listed for Alamance County. Table 3: Federally Protected Species for Guilford County o�on Name Scientific Name Federal Status County Status Small Whorled Pogonia Isotria medeoloides Threatened Guilford - Current Bald and GoldenGuilford Bald Eagle Haliaeetus leucocephalus - Current Eagle Protection Act S&ME also provided a scoping package to the USFWS on October 3, 2016. The scoping package 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 package requested that the USFWS review records they may have had relating to rare, endangered, or threatened species, or high quality natural communities within the vicinity of the project corridor, and provide comment. To date, USFWS has not provided a response. As such, a copy of this PCN will also be provided to the USFWS in Raleigh, N.C, in order to continue compliance with Section 7 of the ESA, with a request that they provide comment directly to your office. Small Whorled Pogonia Status: Federally Listed Threatened Biological Determination: May Affect, Not Likely to Adversely Affect Small whorled pogonia (Isotria medeoloides) is a member of the orchid family. According to the USFWS species description, it usually has a single grayish -green stem that grows about 10 inches tall when in flower and about 14 inches when bearing fruit. The leaves are arranged in a whorl near the top of the stem and beneath the flower. The leaves are grayish -green, somewhat oblong and one to 3.5 inches long. The greenish -yellow flowers are about 0.5 to one inch long and appear in May or June. The fruit, an upright ellipsoid capsule, appears later in the year. This species grows in older hardwood stands of beech, birch, maple, oak, and hickory that have an open understory. Sometimes it grows in stands of softwoods such as hemlock. It prefers acidic soils with a thick layer of dead leaves, often on slopes near small streams, and often occurs on flats or slope bases near canopy breaks. Although the project corridor contains potentially -suitable habitat for the small whorled pogonia, no individuals of this species, nor species with which it is known to co-occur, were observed. Based on our pedestrian field review, it is not anticipated that this project will adversely affect populations of this species. Bald Eagle Status: Bald and Golden Eagle Protection Act Biological Determination: No Effect Bald eagle is a large raptor with a wingspan of approximately seven feet (2.1 meters). Adult individuals of this species have a mainly dark brown plumage with a solid white head and tail. Bald eagles develop adult plumage in the fifth or sixth year. Juveniles of the species exhibit a chocolate brown to blackish plumage with occasional occurrences of white mottling on the tail, belly, and under -wings. Bald eagle's primary diet consists of fish. However, it will feed on birds, mammals, and turtles when fish are not available. S&ME, Inc. Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 Bald eagle is associated with coasts, rivers, and lakes, usually nesting near large bodies of water where it feeds. Nesting habitat in the Carolinas usually occurs in large pine trees along the edge of large bodies of water. The proposed project will not impact large bodies of water, and no areas of potential habitat for this species were observed during field review. Therefore, the project should have no effect on bald eagle. ❖ Historic and Archaeological Resources On October 3, 2016, a scoping letter was submitted to the North Carolina State Historic Preservation Office (SHPO) with a request that they provide comment on the proposed project. The SHPO responded with an October 20, 2016 letter stating that they were aware of no historic resources that would be affected by the project, and therefore had no further comment. A copy of the SHPO letter is included in Appendix VI. •'• Avoidance and Minimization PNG re-routed the proposed pipe to avoid impacts to an additional wetland area that was located in the original alignment, and impacts to WC will be avoided by use of trenchless installation. Construction equipment operating near streams and the Wetland WB will be limited to that necessary for excavation, pipe installation and restoration activities. Vegetation near the stream will be cut at ground level, leaving existing root systems in place to promote re -growth. The non -perpendicular stream and buffer crossings associated with S1 are necessary because the proposed easement abuts and parallels an existing property line. The new gasline was routed in this manner to minimize the landowner impact by not fragmenting the parcel and better preserving its viability for future development, should the owner decide to eventually do so. Appropriate S&EC practices outlined in the most recent version of the "North Carolina Sediment and Erosion Control Planning and Design Manual" and approved by the local governing authority shall be in compliance with specifications governing the proper design, installation, operation, and maintenance of such BMPs to comply with the appropriate turbidity water quality standard. As proposed, the project will comply with applicable conditions of NWP No. 12 and WQC No. 3884. Following the work, the affected areas will be restored to their original grade and contour. As proposed, the project will not result in permanent changes to the ground surface elevation(s) in the area or affect dimension, pattern, or profile of the affected streams. Affected areas are proposed to be restored in accordance with the attached Restoration Plan (Appendix VII) following completion of the work. •'• Mitigation The project will not permanently impact stream channels, as those that are temporarily affected will be restored following construction. While the project will not result in a loss of Waters of the U.S., it will result in permanent conversion of 0.01 acre of forested wetland to herbaceous wetland. Because the conversion impacts do not exceed 0.10 acre, we do not anticipate that compensatory mitigation beyond the proposed avoidance and minimization efforts will be required. As proposed, the project will comply with applicable conditions of NWP No. 12. The project will not result in permanent changes in pre -construction elevation contours or affect dimension, pattern, or profile of affected streams or wetlands. Cleared areas are proposed to be restored in accordance with the attached Restoration Plan (Appendix VII) following completion of the work. S&ME, Inc. Application for NWP No. 12/WQC No. 3884/Buffer Authorization S&ME Project No. 7435-16-053 PNG Southern Alamance System Enhancement November 3, 2016 Of the proposed pipeline crossings, those of Stream S2 (crossings 6 and 7) and considered "allowable with mitigation." The remaining crossings are exempt, as they are perpendicular, do not result in a disturbance width of greater than 40 feet, and will result in a permanent maintenance corridor of 10 feet. Project -wide riparian buffer impacts are detailed in the appropriate table in Appendix III and drawings in Appendix IV. Of these impacts, 1,999 sf of Zone 1 will be permanently converted from forest to grassed easement, and will require mitigation. Using the appropriate multiplier (1,999 sf x 3), PNG is required to purchase 5,997 riparian buffer credits in Cape Fear 03030002. PNG plans to purchase these credits from Restoration Systems, LLC (Appendix VII). • Closing By copy of this correspondence and completed PCN, we are requesting your written concurrence with this NWP No. 12 permit application.

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. The new pipe will be installed in a new 10 -foot wide easement. An additional 15 feet of temporary workspace (TWS) adjacent to the proposed permanent easement will be required to safely install the new pipe. At the wetland area, 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 the wetland 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 the wetland area, 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. 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. 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, new segements of the plastic pipe will be trucked to the site from temporary storage yards, strung along the easement and placed on skids (wooden pedestals). The pipe segments will be heat -welded togegether, 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 the wetland and at streams will be conducted in accordance with the applicable permits. Best Management Practices (BMP's) will be employed at all streams and the wetland crossing to help prevent siltation or inadvertent discharges to a Waters of the U.S. 4.

A query of the NCNHP database, based on the project area mapped with your request, indicates that there are no records for rare species, important natural communities, natural areas, or conservation/managed areas within the proposed project boundary. Please note that although there may be no documentation of natural heritage elements within the project boundary, it does not imply or confirm their absence; the area may not have been surveyed. The results of this query should not be substituted for field surveys where suitable habitat exists. In the event that rare species are found within the project area, please contact the NCNHP so that we may update our records. The attached `Potential Occurrences' table summarizes rare species and natural communities that have been documented within a one -mile radius of the property boundary. The proximity of these records suggests that these natural heritage elements may potentially be present in the project area if suitable habitat exists and is included for reference. Tables of natural areas and conservation/managed area within a one -mile radius of the project area, if any, are also included in this report. Please note that natural heritage element data are maintained for the purposes of conservation planning, project review, and scientific research, and are not intended for use as the primary criteria for regulatory decisions. Information provided by the NCNHP database may not be published without prior written notification to the NCNHP, and the NCNHP must be credited as an information source in these publications. Maps of NCNHP data may not be redistributed without permission. The NC Natural Heritage Program may follow this letter with additional correspondence if a Dedicated Nature Preserve (DNP), Registered Heritage Area (RHA), Clean Water Management Trust Fund (CWMTF) easement, or Federally -listed species are documented near the project area. If you have questions regarding the information provided in this letter or need additional assistance, please contact Suzanne Mason at suzanne.mason&ncdcr.gov or 919.707.8637.

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 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 portions of the easement comprised of wetlands.
