PROJECT DESCRIPTION AND UNDERSTANDING Dewberry Engineers Inc. (Dewberry) was requested by Duke Energy, Carolinas (DEC) to prepare a Natural Resource Assessment (NRA) for the proposed Kerwin Circle Station located in Forsyth County, North Carolina. The project includes the construction of a substation for DEC. The project will consist of tree clearing and grading in the area of the substation. The project area is located in the northwestern portion of Kernersville. The project boundary is east of Talley's Crossing in Kernersville and includes 3.25 acres (Figure 1). The substation will be located on the northern section of the parcel. The project boundary is illustrated within this report on topographic maps and aerial photography (Figures 1 and 3). As part of the NRA, Dewberry provided the following services: • General Soil assessment • General Floodplain assessment • Delineation of wetlands and waters of the U.S. (WOTUS) • Preliminary endangered, threatened and species of special concern assessment • Preliminary historic and cultural resources assessment • GPS location of identified features 2. METHODOLOGY Prior to the site visit, the following resources were reviewed: • Forsyth County, NC GIS • U.S. Fish and Wildlife Service Endangered and Threatened Species and Information for Planning and Conservation (IPaC) Trust Resource Report • Natural Resources Conservation Service (NRCS) Web Soil Map • USGS Topographic Map, Belews Creek, NC 2019 • U.S. Fish and Wildlife National Wetland Inventory (NWI) • North Carolina Department of Natural Heritage Program • Federal Emergency Management Agency (FEMA) Flood Hazard Maps April 2, 2020 1 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.dou f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station During the site visit, field work was conducted in accordance with: • NC Department of Transportation (DOT) Guidance for Preparing Natural Resource Technical Reports • North Carolina Wetland Assessment Method (NCWAM) • North Carolina Stream Assessment Method (NCSAM) • NC Division of Water Quality (NCDWQ) Methodology for Identification of Intermittent and Perennial Streams and Their Origins • Corps of Engineers Wetlands Delineation Manual • Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Eastern Mountains and Piedmont Region (Version 2.0) 3. SITE OVERVIEW The project boundary is located in the piedmont of North Carolina. The topography of the substation parcel is characterized as sloping north towards a mapped pond. The project is in close proximity to cities and major highways. The project boundary is located in the USGS hydrologic unit 03010103 in the Roanoke River Basin (USGS 2017). There are no Outstanding Water Resources, or designated Trout Waters (Tr) along the project boundary. 4. GENERAL SOIL ASSESSMENT The USDA web soil survey (2020) (Figure 2) identifies the following soils within the project boundary: • BtE Bannertown-Toast complex, 15-25% slopes • CID Clifford sandy loam, 10-15% slopes • FaF Fairview fine sandy loam, 15-45% slopes • NaB Nathalie sandy loam, 2-6% slopes • NaC Nathalie sandy loam, 6-10% slopes • TcD Toast sandy loam, 10-15% slopes The USDA web soil survey identifies no hydric soils within the project boundary. 5. GENERAL FLOODPLAIN ASSESSMENT The project boundary is located within an area of minimal flood (Zone X). Appendix A illustrates the approximate project boundary on the FEMA National Flood Hazard maps. 6. DELINEATION OF WETLANDS AND WATERS OF THE US The Clean Water Act (CWA) is an amendment to the Federal Water Pollution Control Act of 1972, which regulates the discharges of pollutants to waters of the United States. Section 404 of the CWA April 2, 2020 2 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.dou f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station establishes a program to regulate the discharge of dredged and fill material into waters of the United States, including wetlands. The EPA administratively oversees the CWA and Section 404 of the CWA (EPA 2017). The US Army Corps of Engineers (USACE) enforces the CWA Section 404 regulatory program through implementation and permitting. To determine the limits and boundaries of waters of the U.S. (WOTUS) and wetlands, a field survey is conducted by walking the extent of the project boundary and identifying the separation boundary between USACE regulated areas (i.e. jurisdictional) from non -regulated areas (non -jurisdictional). Regulated areas may include wetlands, rivers, stream channels, ponds, lakes, seeps and non -tidal waters. Determining the jurisdictional boundaries of resources is a crucial component of planning a project and is required when submitting a permit application to the USACE (USACE 2018). An on -site wetland investigation was conducted within the project boundary to identify the approximate limits of jurisdictional wetlands and WOTUS. The project boundary was identified by Duke Energy, Carolinas as depicted on Sheet 1 (Figure 3). Field indicators of hydrophytic vegetation, hydric soils, and wetland hydrology were observed and recorded to generally determine the approximate wetland boundaries. Boundaries of jurisdictional wetlands and the ordinary high watermark (OHM) of stream channels were flagged with survey ribbon and located using a handheld Trimble GPS unit. 6.1 Wetlands One (1) wetland was delineated within the project boundary. The wetland types were classified by the Cowardian Classification typical of USACE determinations and by the North Carolina Wetland Assessment Method (NCWAM). Figure 3 illustrates the approximate location and extent of the delineated wetlands. These locations are based upon mapping grade GPS and should be considered approximate. Wetlands were flagged and numbered in the field using pink and black striped flagging. Wetland data sheets are provided as Appendix B. NCWAM forms are provided as Appendix C. Table 1 provides a summary of the wetland data collected within the project boundary. Table 1.

Stream classifications are supported by the North Carolina Division of Water Resources (NCDWR) Stream Identification Forms (Version 4.11). Stream order was assessed using the Stahler Stream Order Method. Where April 2, 2020 3 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.docx f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station appropriate, streams were evaluated using North Carolina Stream Assessment Method (NCSAM). Stream channels were flagged at the OHM. Figure 3 illustrates the approximate location and extent of the delineated stream channel. These illustrations are approximate and do not equate a conventional ground survey. Stream channels were flagged and numbered in the field using red and white striped flagging. NCDWR stream identification forms are provided as Appendix D. and NCSAM forms are provided as Appendix E. Table 2 provides a summary of the stream channel data collected within the project boundary.

Open Water Summary Table for Kerwin Circle Station Project Approximate Area Open Water No. Resource ID (acre) Open Water 1 PA 0.44 6.3 Regulatory Considerations The delineation conducted within the project area has not been confirmed by the USACE. In the event the client wishes to pursue permitting, jurisdictional confirmation may be necessary. Depending upon the permitting requirements related to the type and amount of potential impacts to wetlands and WOTUS, the USACE and North Carolina Department of Environmental Quality (NCDEQ) should be notified of the project scope and the required documentation submitted. Clean Water Act Any alteration to WOTUS or wetlands, such as dredging or filling, require authorization by the USACE. The Clean Water Act (CWA) Section 404 permits are issued by the USACE Raleigh Field Office for impacts to WOTUS or wetlands. To be considered valid, a CWA 401 Water Quality Certification (WQC) must accompany the 404 permit. The 401 Certification is issued by NCDEQ to manage specific activities affecting state WOTUS and wetlands. April 2, 2020 4 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.dou f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station If the project anticipates impacts to wetlands or WOTUS, coordination with the USACE and NCDEQ is recommended to finalize a jurisdictional determination of the identified WOTUS and wetlands within the project boundary. Compensatory mitigation may be required if the project permanently impacts wetlands and/or streams. The USACE requires mitigation for unavoidable impacts greater than 150 linear feet of stream and/or greater than 0.10 acre of wetlands. Section 10 of the Rivers and Harbors Act No Section 10 rivers were identified in the project area. Section 10 of the Rivers and Harbors Act requires USACE authorization in order to construct or otherwise alter navigable waters of the U.S. Alteration of waters may include, but is not limited to: placement of structure(s) in or over waters, excavation, dredging, fill, and otherwise obstructing or altering waters. Confirmation by USACE is recommended before commencing any alterations to the delineated WOTUS. 7. THREATENED AND ENDANGERED SPECIES The Endangered Species Act protects species that are federally listed as threatened or endangered. Online and field surveys are conducted to determine the presence of suitable habitat for threatened or endangered species. If suitable habitat is found, a field survey may be needed to confirm or refute the presence of, or the potential presence of the identified threatened or endangered species. Prior to the site visit, an online search through the U.S. Fish and Wildlife Service (USFWS) Information for Planning and Consultation (IPaC) service was conducted to determine the potential presence of threatened or endangered species. The online search determined the possible presence of threatened or endangered species. Table 4 summarizes the threatened or endangered species identified to occur within the project area. Table 4.

Small-anthered bittercress Small-anthered bittercress is a biennial or perennial herb that is endemic to the Dan River Drainage of the Roanoke River Basin. Their habitat consists of moist, wet woods along small to intermittent sized streams, stream banks and seepages above stream banks, wet rock crevices, and sand and gravel bars of small streams. The species prefers full sun or partial shade from trees and shrubs. Soil type preferences include, Rion, Pacolet, and Wateree. The species can occur with poor viability in disturbed areas subject to livestock trampling, silviculture, or encroachment or exotic, invasive species such as Japanese honeysuckle (NCDOT 2010). Habitat Present: Yes An online search of the USFWS identifies the Small-anthered bittercress as occurring in Forsyth County. The soil preference of the plant is listed to include Pacolet, which is located within the project boundary. The habitat preference for the plant is along intermittent streams in wooded areas and seepages above streambanks (NCDOT 2010). These habitats are found within the project boundary. Biological Conclusion: May Affect The optimal survey window for the Small-anthered bittercress is April through May. The NRA site visit was conducted in March 2020. A surveyfor the Small-anthered bittercress should be conducted during the next optimal survey window. Northern Lone -Eared Bat Northern long-eared bat (NLEB) is a medium-sized bat with a body length of 3 to 3.7 inches. Their summer habitat consists of roosting in cavities or crevices of both live and dead trees (snags). They can also be found roosting in caves and mines. Their wintering habitat consists of hibernating in caves and mines. They prefer these habitats because it provides a constant temperature, high humidity, and no air currents. The northern long-eared bats feeding habitat is primarily understory forests to catch moths, flies, and beetles. The range for the northern long-eared bat includes much of eastern and north central United States (USFWS, 2015). Habitat Present: Yes An online search of the USFWS identifies the NLEB as occurring in Forsyth County. The habitat preference is listed to include living and dead trees for summer habitat and understory trees for feeding habitat. These habitats are found within the project area. An online search of the USGS Mineral Resources Online Spatial Data System was utilized to search for mines that could be possible wintering habitat for the NLEB. The online search revealed no mineral resources within three (3) miles of the project boundary. April 2, 2020 6 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.dou f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station Biological Conclusion: May Affect Operations will include tree clearing. These activities may affect bat populations. Forsyth County is identified by the USFWS to be within the White Nose Syndrome (WNS) range for the NLEB. For areas of the country impacted by the WNS (Le., areas inside of the WNS zone), incidental take, [such as accidental death caused by tree clearing][ofthe NLEB] is prohibited under the following circumstances: • If it occurs within the hibernaculum • If it results from tree removal activities o The activity occurs within 0.25 miles (0.4 km) of a known hibernaculum; or, o The activity cuts or destroys a known, occupied maternity roost tree or other trees within a 150 foot radius of the maternity roost tree during the pup season from June 1 through July 31' (USFWS, 2017) There are no known or documented hibernacula or maternity trees listed by the NC Natural Heritage Program along the project boundary. However, as a precautionary measure, consider limiting mature tree clearing to outside of the pup season (June 1 through July 31). If in the event, DEC decides to conduct a NLEB survey, the USFWS states that the biological survey guidance for the Indiana bat can be used to survey for the NLEB. The optimal survey window for the bats is May through August (summer) and January through February (winter). Bog Turtle Bog turtle habitat consists of open, groundwater fed wetlands along streams or seeps on hillsides. The habitats are designated as mountain bogs by the North Carolina Heritage Program, but they can also be wet pastures and old drainage areas. The habitat is found between 700 and 4,500 feet above sea level in the Western Piedmont of North Carolina. The soil types are poorly drained silty foams, Those soil types may include, Arkaqua, Chewacla, Dellwood, Codorus complex, Hatboro, Nikwasi, Potomac-lotla complex, Reddies, Rosman Tate-Cullowhee complex, Toxaway, Tuckasegee-Cullasasja complex, Tusquitee, Watauga, and Wehadkee (USFWS, 2008) Habitat Present: No An online search of the USFWS identifies the Bog turtle as occurring in Forsyth County. The habitat preference is wet mountain bogs and areas with soil types that are not found within the project area. These habitats are found not within the project area. Biological Conclusion: No Effect The Bog Turtle is listed as threatened due to similarity of appearance and does not require Section 7 consultation with the USFWS. No bog turtles were observed during field activities, however no specific surveys were performed due to the T(S/A) status of the species. A review April 2, 2020 7 P:\50126132\Adm\Reports\NRA\2020.4.2 Kerwin Circle Substation.docx f Dewberry' Duke Energy, Carolinas Natural Resource Assessment: Kerwin Circle Station of the NHP records on May 31, 2019 indicates no known occurrences within 1.0 mile of the study area. Bald Eagle The bald eagle is protected under the Bald and Golden Eagle Protection Act, and enforced by the USFWS. Habitat for the bald eagle primarily consists of mature forests in proximity to large bodies of open water for foraging. Large dominant trees are utilized for nesting sites, typically within 1.0 mile of open water. A desktop-GIS assessment of the project study area, and the area within a 1.0 mile radius of the project limits, was performed by Dewberry on February 12, 2020 using 2019 color aerials. Water bodies large enough or sufficiently open to be considered potential feeding sources were identified within 1.0 mile radius of the project area, including Kernersville Lake. A ground survey of the project study area and the area within 660 feet of the project limits was conducted. No bald eagles were observed along the project boundary during the site visits. Additionally, a review of the NHP database on March 3, 2020 revealed no known occurrences of this species within 1.0 mile of the project area. Due to the lack of known occurrences, and no observations of bald eagles within the 660 foot perimeter of the project area, it has been determined that this project will not affect this species. 8. HISTORIC RESOURCES An online search of the North Carolina State Historical Preservation Office (NCSHPO) revealed no historic listings adjacent to the project boundary. The North Carolina State Preservation Office registry map is provided in Appendix F. 9. SUMMARY Dewberry delineated one (1) wetland and four (4) stream channels within the project boundary. Any unavoidable impacts to these resources should be discussed with USACE and NCDEQ prior to construction. Three (3) threatened or endangered species were listed to occur within the project boundary. Two (2) species were determined to have a biologic conclusion of "may affect" by the proposed project and one (1) species was determined as "no effect" due to lack of suitable habitat within the project area. A plant survey for the Small-anthered bittercress should be conducted during the next optimal survey window during April -May. No eligible historic resources were identified within the project boundary.

Buffer Structure — streamside area metric (skip for Tidal Marsh Streams) Consider for left bank (LB) and right bank (RB) for Metric 19 ("Vegetated" Buffer Width). LB RB ®A ®A Mature forest ❑B ❑B Non -mature woody vegetation or modified vegetation structure ❑C ❑C Herbaceous vegetation with or without a strip of trees < 10 feet wide ❑D ❑D Maintained shrubs ❑E ❑E Little or no vegetation 21. Buffer Stressors — streamside area metric (skip for Tidal Marsh Streams) Check all appropriate boxes for left bank (LB) and right bank (RB). Indicate if listed stressor abuts stream (Abuts), does not abut but is within 30 feet of stream (< 30 feet), or is between 30 to 50 feet of stream (30-50 feet). If none of the following stressors occurs on either bank, check here and skip to Metric 22: Abuts < 30 feet 30-50 feet LB RB LB RB LB RB ❑A ❑A ❑A ❑A ❑A ❑A Row crops ❑B ❑B ❑B ❑B ❑B ❑B Maintained turf ❑C ❑C ❑C ❑C ❑C ❑C Pasture (no livestock)/commercial horticulture ❑D ❑D ❑D ❑D ❑D ❑D Pasture (active livestock use) 22. Stem Density — streamside area metric (skip for Tidal Marsh Streams) Consider for left bank (LB) and right bank (RB) for Metric 19 ("Wooded" Buffer Width). LB RB ®A ®A Medium to high stem density ❑B ❑B Low stem density ❑C ❑C No wooded riparian buffer or predominantly herbaceous species or bare ground 23. Continuity of Vegetated Buffer — streamside area metric (skip for Tidal Marsh Streams) Consider whether vegetated buffer is continuous along stream (parallel). Breaks are areas lacking vegetation > 10 feet wide. LB RB ®A ®A The total length of buffer breaks is < 25 percent. ❑B ❑B The total length of buffer breaks is between 25 and 50 percent. ❑C ❑C The total length of buffer breaks is > 50 percent. 24. Vegetative Composition — streamside area metric (skip for Tidal Marsh Streams) Evaluate the dominant vegetation within 100 feet of each bank or to the edge of the watershed (whichever comes first) as it contributes to assessment reach habitat. LB RB ®A ®A Vegetation is close to undisturbed in species present and their proportions. Lower strata composed of native species, with non-native invasive species absent or sparse. ❑B ❑B Vegetation indicates disturbance in terms of species diversity or proportions, but is still largely composed of native species. This may include communities of weedy native species that develop after clear -cutting or clearing or communities with non-native invasive species present, but not dominant, over a large portion of the expected strata or communities missing understory but retaining canopy trees. ❑C ❑C Vegetation is severely disturbed in terms of species diversity or proportions. Mature canopy is absent or communities with non-native invasive species dominant over a large portion of expected strata or communities composed of planted stands of non -characteristic species or communities inappropriately composed of a single species or no vegetation. 25. Conductivity — assessment reach metric (skip for all Coastal Plain streams) 25a. ❑Yes ®No Was conductivity measurement recorded? If No, select one of the following reasons. ❑No Water ❑Other: 25b. Check the box corresponding to the conductivity measurement (units of microsiemens per centimeter). ❑A < 46 ❑B 46 to < 67 ❑C 67 to < 79 ❑D 79 to < 230 ❑E >_ 230 Notes/Sketch Draft NIC SAM Stream Rating Sheet Accompanies User Manual Version 2.1 Stream Site Name Kerwin Circle Station Date of Assessment 2/25/2020 Stream Category Pb1 Assessor Name/Organization K.
