Salisbury St. Archdale Bldg. 9th Floor Raleigh, NC 27604 RE: Nationwide Permit 39/GC 4139 Aberdeen Transmission Headquarters Aberdeen, North Carolina DKE-17280 Dear Ms. Higgins: On behalf of Duke Energy Progress, LLC, we are applying for a Nationwide Permit 39 from the US Army Corps of Engineers (USACE) and a Water Quality Certification 4139 from the NC Division of Water Resources (DWR) for proposed impacts to jurisdictional wetlands associated with the project known as Aberdeen Transmission Headquarters. The project area is located at the intersection of NC Highway 5 and Allison Page Road in the Town of Aberdeen, Moore County, North Carolina. The following attachments are included as part of this permit application: > Signed Agent Authorization Form > Fig. 1 - USGS Quad — "Southern Pines" > Fig. 2 - Moore County Soil Survey (Sheet: 11) > Fig. 3.1 - Existing Conditions > Fig. 3.2 - Existing Conditions with aerial imagery > Fig. 4 - Overall Impact Exhibit > Impact Exhibit Inset— Inset 1 > Pre -Construction Notification & Supplemental Information > USACE Wetland Data Forms (1 wetland form, 1 upland form) > Preliminary Jurisdictional Determination request package (see PJD cover letter for list of PJD attachments) PROJECT LOCATION/HABITAT: The project area is located at the intersection of NC Highway 5 and Allison Page Road in the Town of Aberdeen, North Carolina within Moore County. The 21.63 -acre project area is comprised of one parcel (Moore County PIN: 856011565342) owned by Duke Energy Progress, LLC. The southern portion of the property is developed and includes two buildings, paved parking lots, a gravel storage yard, and supporting infrastructure utilized by the Duke Energy Transmission Group. The parcel currently consists of 4.85 acres of impervious area (22.4 percent of the parcel area). The northern portion of the parcel is forested except creating experiences through experience 1 of4 'J MCADAMS NATIONWIDE PERMIT 39/GC 4139 > DKE-17280 for an overhead utility easement that extends from Hwy 5 south to the developed portion of the parcel. Land use in the vicinity includes commercial and light industrial uses on the north side of Hwy 5, and forested areas interspersed with low density residential and commercial uses adjacent to the west, south, and east. JURISDICTIONAL FEATURES: The project area is in the Aberdeen Creek Watershed (HUC 030402030202) within the Lumber River basin. The subject property drains southwest and east to two unnamed tributaries to Aberdeen Creek, which is designated Class C. The project area is depicted on both a current U.S. Geological Survey (USGS) map (Figurel) and the Moore County NRCS Soil Survey (Figure 2). There are no stream features mapped on the USGS map; There is one potential stream feature (Stream Feature A) depicted on the Soil Survey map. McAdams staff conducted field investigations on June 28 and 29, 2017 with the objective of flagging streams and wetlands (or Waters of U.S.) as defined by the 1987 U.S. Army Corps of Engineers (USACE) Wetland Delineation Manual. Based on our field investigations, one (1) potential headwater palustrine forested broad-leaved deciduous wetland Water of the U.S. was identified within the study area. A total of approximately 0.401 acres of wetland were flagged. No stream features were identified within the study area. Figures 3.1 and 3.2 depict the surveyed extents of the delineated wetland feature. The jurisdictional wetland and stream delineation performed by McAdams has not been verified by the US Army Corps of Engineers (USACE). A Preliminary Jurisdictional Determination is being requested concurrently with this permit application. There are no state or local riparian buffer rules in effect for the project area. PROPOSED IMPACTS: Duke Energy Progress is proposing to modify the existing operations on the property with construction of a new facility (approximately 11,586 sf) to accommodate the Transmission staff from the Administration building as well as the Relay and Line and Service crews currently located at this site. A re -design of the laydown area will also provide more efficient space for materials and a separate entrance and exit. In addition, a new 15,360-sf Fleet Services Garage with four truck bays with pull-through access, along with a pull-through wash bay will also be constructed. The existing garage on the lease property will be vacated. The site was designed to minimize impacts to aquatic resources while making the necessary site improvements. There is one area of wetland impact associated with the proposed site improvements. The proposed project will result in 0.024 acres (1,037 sf) of wetland impact. No stream or riparian buffer impacts will result from this project. All sedimentation and erosion control measures will be implemented before construction to minimize runoff. Typical construction equipment, such as a long-arm track -hoe, front end loader, and bush hog will be used for the initial clearing. creating experiences through experience 2 of 4 'J MCADAMS NATIONWIDE PERMIT 39/GC 4139 > DKE-17280 TOTAL PROPOSED WETLAND IMPACTS: Impact Location Impact Type Newly Proposed (acres) Inset 1 (perm.) Grading 0.024 TOTAL 0.024 acres AVOIDANCE and MINIMIZATION: Impacts to jurisdictional Waters of the U.S. have been minimized to the maximum extent practicable. There are 0.024 acres of impacts to Wetland A associated with a proposed paved area adjacent to the proposed fleet garage. Wetland impacts have been limited to less than six percent of the total 0.401 acres of Wetland A. There are no proposed impacts to jurisdictional streams or riparian buffers. Because the total proposed impacts to Waters of the U.S. are less than 1/10th of an acre, mitigation in the form of avoidance and minimization is proposed. Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation, as described in the Erosion Control Plan sheets to be reviewed and approved by the NC Division of Land Resources and/or the Town of Aberdeen. All work will take place during dry conditions and can be facilitated from high, non - jurisdictional, stable ground adjacent to the shoreline. The contractor shall install silt fence, inlet protection, sediment traps, diversion ditches, tree protection, and other measures as shown on the erosion control plans, clearing only as necessary to install these devices. All erosion and sediment control measures will be checked for stability and operation following every runoff producing rainfall, but in no case less than once every week. Any needed repairs will be made immediately to maintain all measures designed. An erosion control inspections report is required and will be kept by the owner's representative. All slopes shall be graded no steeper than the angle that can be retained by vegetative cover or other adequate erosion control devices or structures. No material for construction will be placed in wetland or streams at any time. Excavation will be limited to the area necessary for site preparation; all excavated material will be placed and retained on high ground above the flood pool elevation. All excavated material will be placed landward of the normal pool elevation contour on high ground and confined by adequate dikes or other retaining structures to prevent erosion and sedimentation into adjacent streams and wetlands. MITIGATION: There is less than 1/10 of an acre of total impacts to wetland waters of the U.S. on the site. There are no proposed impacts to jurisdictional streams or riparian buffers. The applicant proposes mitigation in the form of avoidance and minimization for impacts to waters of the U.S. STORMWATER MANAGEMENT: The proposed development will be subject to the stormwater management performance standards for development set forth in the Town of Aberdeen Land Development Ordinance (Article XVI, Section 152-263). A level spreader is proposed to meet the referenced standard. The proposed improvements will result in an increase of approximately 3.65 acres of impervious area, bringing the total site impervious area to 8.50 acres. To mitigate the proposed development, a portion of the site drainage will be collected and directed to a creating experiences through experience 3 of4 'J MCADAMS NATIONWIDE PERMIT 39/GC 4139 > DKE-17280 level spreader for treatment. The proposed facility is designed to treat runoff generated from a 0.75 in/hr storm event with larger storms bypassing the facility. Consideration of this project is greatly appreciated.

Project Information and Prior Project History 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: The project area is located at the intersection of NC Highway 5 and Allison Page Road in the Town of Aberdeen, North Carolina within Moore County. The 21.63 -acre project area is comprised of one parcel (Moore County PIN: 856011565342) owned by Duke Energy Progress, LLC. The southern portion of the property is developed and includes two buildings, paved parking lots, a gravel storage yard, and supporting infrastructure utilized by the Duke Energy Transmission Group. The parcel currently consists of 4.85 acres of impervious area (22.4 percent of the parcel area). The northern portion of the parcel is forested except for an overhead utility easement that extends from Hwy 5 south to the developed portion of the parcel. Land use in the vicinity includes commercial and light industrial uses on the north side of Hwy 5, and forested areas interspersed with low density residential and commercial uses adjacent to the west, south, and east. The project area is in the Aberdeen Creek Watershed (HUC 030402030202) within the Lumber River basin. The subject property drains southwest and east to two unnamed tributaries to Aberdeen Creek, which is designated Class C. The project area is depicted on both a current U.S. Geological Survey (USGS) map (Figurel) and the Moore County NRCS Soil Survey (Figure 2). There are no stream features mapped on the USGS map; There is one potential stream feature (Stream Feature A) depicted on the Soil Survey map. McAdams staff conducted field investigations on June 28 and 29, 2017 with the objective of flagging streams and wetlands (or Waters of U.S.) as defined by the 1987 U.S. Army Corps of Engineers (USACE) Wetland Delineation Manual. Based on our field investigations one (1) potential headwater palustrine forested broad-leaved deciduous wetland Water of the U.S. was identified within the study area. A total of approximately 0.401 acres of wetland were flagged. No stream features were identified within the study area. Figures 3.1 and 3.2 depict the surveyed extents of the delineated wetland feature. The jurisdictional wetland and stream delineation performed by McAdams has not been verified by the US Army Corps of Engineers (USACE). A Preliminary Jurisdictional Determination is being requested concurrently with this permit application. There are no state or local riparian buffer rules in effect for the project area. 3d. Explain the purpose of the proposed project: The purpose of the proposed project is to modify and expand the existing Aberdeen Transmission Headquarters facility to accommodate the Transmission staff from the Administration Building as well as the Relay and Line and Service crews currently located at this site. creating experiences through experience 1 of 3 'J MCADAMS PCN FORM SUPPLEMENTAL INFORMATION > DKE-17280 3e. Describe the overall project in detail, including the type of equipment to be used: Duke Energy Progress is proposing to modify the existing operations on the property with construction of a new facility (approximately 11,586 sf) to accommodate the Transmission staff from the Administration building as well as the Relay and Line & Service crews currently located at this site. A re -design of the laydown area will also provide more efficient space for materials, and a separate entrance and exit. In addition, a new 15,360-sf Fleet Services Garage with four truck bays with pull-through access, along with a pull-through wash bay will also be constructed. The existing garage on the lease property will be vacated. The site was designed to minimize impacts to aquatic resources while making the necessary site improvements. There is one area of wetland impact associated with the proposed site improvements. The proposed project will result in 0.024 acres (1,037 sf) of wetland impact. No stream or riparian buffer impacts will result from this project. All sedimentation and erosion control measures will be implemented before construction to minimize runoff. Typical construction equipment, such as a long-arm track -hoe, front end loader, and bush hog will be used for the initial clearing. Section D. Impact Justification and Mitigation 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. Impacts to jurisdictional Waters of the U.S. have been minimized to the maximum extent practicable. There are 0.024 acres of impacts to Wetland A associated with a proposed paved area adjacent to the proposed fleet garage. Wetland impacts have been limited to less than six percent of the total 0.401 acres of Wetland A. There are no proposed impacts to jurisdictional streams or riparian buffers. Because the total proposed impacts to Waters of the U.S. are less than 1/10th of an acre, mitigation in the form of avoidance and minimization is proposed. 1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. The proposed development will be subject to the stormwater management performance standards for development set forth in the Town of Aberdeen Land Development Ordinance (Article XVI, Section 152-263). A level spreader is proposed to meet the referenced standard. The proposed improvements will result in an increase of approximately 3.65 acres of impervious area, bringing the total site impervious area to 8.50 acres. To mitigate the proposed development, a portion of the site drainage will be collected and directed to a level spreader for treatment. The proposed facility is designed to treat runoff generated from a 0.75 in/hr storm event with larger storms bypassing the facility. Proper sedimentation and erosion control methods will be utilized during all phases of construction and installation, as described in the Erosion Control Plan sheets to be reviewed and approved by the NC Division of Land Resources and/or the Town of Aberdeen. All work will take place during dry conditions and can be facilitated from high, non - jurisdictional, stable ground adjacent to the shoreline. The contractor shall install silt fence, inlet protection, sediment traps, diversion ditches, tree protection, and other measures as shown on the erosion control plans, clearing only as necessary to install these devices. All erosion and sediment control measures will be checked for stability and operation following every runoff producing rainfall, but in no case less than once every week. Any creating experiences through experience 2 of 3 M MCADAMS PCN FORM SUPPLEMENTAL INFORMATION > DKE-17280 needed repairs will be made immediately to maintain all measures designed. An erosion control inspections report is required and will be kept by the owner's representative. All slopes shall be graded no steeper than the angle that can be retained by vegetative cover or other adequate erosion control devices or structures. No material for construction will be placed in wetland or streams at any time. Excavation will be limited to the area necessary for site preparation; all excavated material will be placed and retained on high ground above the flood pool elevation. All excavated material will be placed landward of the normal pool elevation contour on high ground and confined by adequate dikes or other retaining structures to prevent erosion and sedimentation into adjacent streams and wetlands. Section F. Supplementary Information 5d. What data sources did you use to determine whether your site would impact Endangered Species or Designated Critical Habitat? The USFWS IPaC web tool (https:Hecos.fws.gov/ipac/) and the NC Natural Heritage Program Data Explorer (http://ncnhde.natureserve.org/content/map) were accessed on December 5, 2017 to determine if the project would impact Endangered Species or Designated Critical Habitat. An official species list for the project area was generated using the USFWS IPaC regulatory review tool. The official species list identified the red -cockaded woodpecker (Picoides borealis), Cape Fear shiner (Notropis mekistocholas), American chaffseed (Schwalbea americana), and Michaux's sumac (Rhus michauxii) as federally listed species that may occur within the project area. There are no critical habitats within the project area. Based on field inspections, it is believed that no adverse impacts to threatened and endangered species and their known habitat will occur due to the construction of the proposed project. 7b. What data sources did you use to determine whether your site would impact historic or archeological resources? A review of the North Carolina State Historic Preservation Office interactive map (http://gis.ncdcr.gov/hpoweb/), which shows the locations of properties and districts in Moore County, North Carolina entered in the National Register of Historic Places, conducted on December 5, 2017 did not reveal any listings within the project area. It is believed the proposed project will not occur in or near an area that has been designated as having historic or cultural preservation status by the state, federal, or tribal governments. creating experiences through experience 3 of 3 WETLAND DETERMINATION DATA FORM — Eastern Mountains and Piedmont Region f /� Project'Site: L drm A 7r i✓ City/Coup j!`� �4 . ��� Sampling Date: ;L l Applicant/Owner: _ State, Sampling Point: nisi Investigator(s): �) % Section, Township, Range: Landform (hillslope, terrace, etc.): rr Local relief (concave, convex, none): P.
