A copy of the Stormwater Management Permit Application Form is in Exhibit 1.0 of this plan and a copy of the deed has been provided in Exhibit 6.0. Soil disturbing activities will include: obstruction clearing, erosion and sediment control installation; gravel road and construction entrance installation; grading; and solar panel and equipment installation; and final stabilization. Please see the USGS Quadrangle Map and Site Improvement Plans drawings for more information. 2.0 EXISTING SITE CONDITIONS • The site consists of woods with wetlands along the western side of the site,and a gravel road that runs along the eastern border. Residential lots on the north, west and southwest borders of the site,Gillespie Street to the southeast and an empty lot with an existing sediment basin to the east. • The USDA Web Soil Report consists of Blaney loamy sand(BaB),2 to 8 percent slopes,Candor sand(CaD), 8 to 15 percent slopes,Lakeland sand(LaB), 1 to 8 percent slopes,Lakeland-Urban land complex(LbB), 1 to 8 percent slopes,water(w),and Wgram-Urban land complex(WgB),0 to 8 percent slopes. Blaney consists of well-drained soil, Candor consists of somewhat excessively drained soil, Lakeland consists of excessively drained soil, and Wagram-Urban consists of well-drained soil. Please see the USDA NRCS Custom Soil Resource Report in Appendix 4.0 for soil information. • The HUC code is 030300040610 for Little Rockfish Creek. • The FEMA FIRM panel 3720042400J,effective 01/05/2007,identifies the site as zone X with an area of minimal flood hazard. P.0574167.E.TE.8121 ©October 2023 -1- Booth&Associates 3.0 DESIGN APPROACH The proposed project is designed as a low-density project with a BUA not exceeding 24% impervious area. The solar panels will be installed in a manner to maintain a uniform slope and grading will be implemented as needed to maintain slopes less than 8%to maintain sheetflow as shown on sheet CG 102 and sheet CG202 of the accompanying drawing set.Natural infiltration will be promoted throughout the site by maintaining 14 ft disconnection between the 12 ft wide panels as shown on sheet CG20 1 of the drawing set and by providing permanent seeding consisting of a mixture of warm and cool season grasses as stated in the permanent seeding requirements on sheet CG501. The vertical clearance of the panels will be less than 10 feet to prevent erosion at the panel driplines as shown in the detail on sheet CG503. As construction is ending and permanent vegetation is being established,a 30'strip of land from the east side of the new impervious area shall be maintained to serve as a disconnected impervious vegetated area. This area is to be well vegetated with white clover and bahiagrass and is to be uncompacted to promote infiltration. This area is highlighted in yellow in the image below,which is taken from Sheet CG202 of the Site Improvement Plans drawing set. Permanent seeding notes are provided on Sheet CG501 of the drawing set. i CIS PROPOSED SOLAR I f• ',_ - R- 86.5'� i ARRAY PROJECT � • \ , I k. > " • AREA • 12.23 ACRES a (INSIDE FENCE) \ 4 •. a 0 i\ • \. � `Y PROPOSED ACCESS ^� \ 1 I \ � 1 j I 1�r.��..

In the space provided below,briefly summarize how the stormwater runoff will be treated. The project in question is a solar utility station and will be a low density project with impervious BUA not exceeding 24% impervious area. Stormwater is to be treated by disconnection between rows of solar panels in slopes less than 8%. Compaction of subsoils will be avoided for proper water infiltration and sheet flow will be maintained throughout.All panels will not exceed a 10'vertical clearance to prevent erosion at driplines. Permanent grasses for treatment are bahiagrass and white clover mechanically maintained thru mowing. During site construction,two temporary skimmer basins,one temporary sediment basin,and silt fence will be used to treat runoff. 2.a.If claiming vested rights,identify the supporting documents provided and the date they were approved: n Approval of a Site Specific Development Plan or PUD Approval Date: n Valid Building Permit Issued Date: ❑ Other: Date: b.If claiming vested rights,identify the regulation(s)the project has been designed in accordance with: n Coastal SW-1995 n Ph II-Post Construction 3.

According to the Cumberland County Geographic Information System (GIS)website, the Parcel Identification Number(PIN) is 0424-66-0123 (43.60 acres). The site includes approximately 43.60 acres, as shown on the Site Location Map (Appendix I, Figure 1).The PSA currently consists of a grassy vacant lot and wooded land.The purpose of this study was to identify and delineate jurisdictional Waters of the U.S. (WOUS)within the project study area (PSA). Wetlands are defined by the United States Army Corps of Engineers (USACE) and the United States Environmental Protection Agency (EPA) as "those areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and under normal circumstances, do support a prevalence of vegetation typically adapted for life in saturated soil conditions." In order for an area to be classified as wetland, hydrophytic vegetation, hydric soils, and wetland hydrology indicators must be present described in the 1987 "Corps of Engineers Wetlands Delineation Manual" and the Appropriate Regional Supplement. 2.0 METHODOLOGY The findings of the WOUS delineation is based on ECS' professional judgment and application of the technical criteria presented in the 1987 USACE Wetlands Delineation Manual and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region,Version 2.0 dated November 2010. ECS completed the following tasks to identify and delineate potentially jurisdictional WOUS boundaries onsite: 2.1 Literature Review ECS reviewed supporting information from publicly-available databases to identify possible ecological effects the project may have on potential state- and/or federally-jurisdictional water resources. During the desktop review, ECS documented relevant, site-specific details (e.g., topographic characteristics, soil composition, recent precipitation, level of disturbance, plant community structure, etc.)and integrated the obtained information with the onsite delineation effort. 2.2 Methodology for Field Investigation Wetland boundaries were delineated using the routine onsite determination method described in the USACE Manual and Regional Supplement, in conjunction with the Atlantic and Gulf Coastal Plain 2020 Regional Wetland Plant List and the USDA Soil Survey. ECS Project#49:20775 Page 1 ff August 21, 2023 ECS performed onsite wetland delineations as described above. First, site hydrology was observed and the plant community within the data plot was characterized. The dominant plant species within each community were then identified, and it was determined whether or not hydrophytic (wetland) plants dominated the plant community. The USFWS has defined five wetland plant indicator categories including: • Obligate wetland (OBL)- has>99% probability of occurring in wetlands • Facultative wetland (FACW)- has 66%to 99% chance of occurring in wetlands • Facultative (FAC)- has 33%to 66% chance of occurring in wetlands • Facultative upland (FACU)- has 1 to 33% chance of occurring in wetlands • Upland (UPL)- has <1% chance of occurring in wetlands • No Indicator(NI) - no wetland indicator for the specified species, considered UPL Plants identified as OBL, FACW, or FAC are considered wetland plants(or hydrophytes) by USACE. In areas determined to have hydrophytic vegetation and potential wetland hydrology, an approximately 16-24 inch hand auger soil boring or shovel test pit was completed to determine if hydric soils were present. The soil boring was also inspected to determine if indicators of wetland hydrology(inundation, soil saturation, etc.)were present. Once an area is determined to be a wetland, further testing was performed to locate the wetland/ upland (non-wetland) boundary. A second soil data point was completed in the upland area to document non-wetland conditions. Wetland boundaries were marked with consecutively numbered surveyor's ribbon flags. Data forms specified in the Regional Supplement were completed for each wetland and non-wetland soil data point location. The data forms recorded the vegetation, soils, and hydrology observations used in making the wetland determinations. 2.3 Methodology for Delineating Streams During the field investigation for wetlands, ECS identified potential streams onsite that could be considered jurisdictional by state and federal regulatory agencies. ECS used field indicators such as flow,substrate composition, presence/absence of defined bed and banks, origin of hydrologic source, presence/absence of vegetation in the stream channel, and composition and relative abundance of resident benthic macroinvertebrates to classify onsite streams into three stream types: ephemeral, intermittent, and perennial. RGL No. 05-05 provides guidance on identifying physical indicators of Ordinary High Water Mark (OHWM) as defined in 33 CFR Sections 328.3(e) and 329.11(a)(1) and discusses implementation of other appropriate means that consider the characteristics of the surrounding areas to establish the lateral limits of jurisdiction over tidal and non-tidal waters. Per RGL No. 05-05, "the lateral limits of jurisdiction over non-tidal water bodies extend to the [OHWM], in the absence of adjacent wetlands. When adjacent wetlands are present, CWAjurisdiction extends beyond the OHWM to the limits of the adjacent wetlands". ECS Project#49:20775 Page 2 ff August 21, 2023 3.0 FINDINGS 3.1 Literature Review ECS professionals reviewed the U.S. Geological Survey(USGS)Topographic Map, U.S. Department of Agriculture Natural Resource Conservation Service(USDA-NRCS)Web Soil Survey,the Soil Data Access (SDA) Hydric Soils List, the Federal Emergency Management Agency (FEMA) Floodplain Mapping Service, U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) Wetlands Mapper, and available aerial photographs to identify potentially jurisdictional Waters of the U.S. (i.e., streams, wetlands, natural ponds, lakes) and available watershed information. 3.1.1 Literature Review Summary The following is a summary of the available desktop information that was reviewed as part of this study: • According to the Hope Mills (North Carolina) USGS Topographic Map Quadrangle dated 1987 (Appendix I, Figure 2) depicts ponds and unnamed tributary to Rockfish Creek within the PSA.The PSA ranges from approximately 125 to 185 feet above mean sea level (MSL). • According to the USDA-NRCS Web Soil Survey(Appendix I, Figure 3), the PSA consists of the following soil map units: BaB - Blaney loamy sand, 2 to 8 percent slopes; CaD - Candor sand, 8 to 15 percent slopes; LaB - Lakeland sand, 1 to 8 percent slopes; LbB - Lakeland-Urban land complex, 1 to 8 percent slopes; W - Water; and WgB - Wagram-Urban land complex, 0 to 8 percent slopes. The aforementioned soils are not listed on the SDA Hydric Soils List for Cumberland County, North Carolina.A pond is depicted on the southern portion of the PSA. • The USFWS NWI map (Appendix I, Figure 4) depicts wetlands within the PSA. The NWI Classifications indicates the following: R4SBC- intermittent riverine feature with a streambed that is seasonally flooded; RSUBH, - unknown perennial riverine feature with an unconsolidated bottom that is permanently flooded; PEM1 Fh - emergent palustrine feature that is persistent, semi-permanently flooded, and diked/impounded; and PUBHh - palustrine feature with an unconsolidated bottom that is permanently flooded and diked/ impounded.The site is located within the Upper Cape Fear watershed and is identified as Hydrologic Unit Code (HUC) 03030004. • The FEMA Flood Insurance Rate Maps (FIRMs), Panel 3720042400J, dated January 5, 2007 (Appendix I, Figure 5) indicates the PSA is located in unshaded Zone X. These areas are determined to be outside the 0.2%Annual Chance Floodplain. • ECS reviewed the NOAA LiDAR Elevation Data of the site (Appendix I, Figure 6). The on-site elevations range from approximately 122 feet above MSL to approximately 196 feet above MSL. ECS Project#49:20775 Page 3 ff August 21, 2023 3.2 Field Investigation Findings ECS personnel conducted the field investigation on August 10, 2023. The last precipitation event prior to the site reconnaissance was on August 8, 2023 and approximately 0.25 inches of precipitation was recorded. During the reconnaissance, ECS observed the PSA for evidence of WOUS, including ponds, streams, and wetlands. Potential streams and ponds were marked with blue flagging tape and potential wetland areas were marked with pink flagging tape. Potential features were located using a Trimble GeoX hand-held GPS unit capable of sub-foot accuracy. ECS identified five potentially jurisdictional areas summarized in the table below: Table 1: Potential WOUS Summary Table Approximate Linear Feet(if Feature ID Approximate Acreage applicable) Stream S1 0.18 acre 1,072 LF Wetland W1 0.17 acre N/A Wetland W2 0.54 acre N/A Wetland W3 0.37 acre N/A Pond P1 1.83 acres N/A 3.2.1 Wetland Summary ECS observed three potentially jurisdictional wetlands areas(W1-W3)within the PSA.Wetland W1 was observed on the northern portion of the PSA, abutting Stream S1. Wetland W2 was observed on the central-western portion of the PSA, abutting Stream S1 and Pond P1. Wetland W3 was observed on the southwestern portion of the PSA and was observed abutting Stream S1. The wetland areas exhibited wetland indicators of hydrophytic vegetation, wetland hydrology, and hydric soils during the site reconnaissance. The wetland areas are depicted on the Waters of the U.S. Delineation Map (Appendix I, Figure 7). Photographs of the wetlands are presented in Appendix II. 3.2.2 Stream Summary ECS observed one potentially jurisdictional stream (S1)within the PSA. Stream S1 was observed transecting the western portion of the PSA, flowing north to south. The stream had well defined bed and banks, assorted substrate, an Ordinary High Water Mark (OHWM), and standing and/or flowing water was noted during the site reconnaissance.The stream varied from approximately two to twenty feet in width and varied from approximately less than a foot to four feet in depth. The stream is depicted on the Waters of the U.S. Delineation Map(Appendix I, Figure 7). Photographs of the stream is presented in Appendix II. ECS Project#49:20775 Page 4 ff August 21, 2023 4.0 REGULATORY DISCUSSION After review of the findings in this report and at the client's request, ECS can coordinate with the USACE and the NCDWR to conduct a jurisdictional determination and field visit, if necessary. The timeline of this process is dependent on the availability of the regulatory agency. ECS recommends receipt of the formal jurisdictional determination letter from the necessary agencies prior to conducting any land-disturbance activities. The USACE can issue an individual permit or a general permit to authorize activities in WoUS. There are two types of general permits - nationwide permits and regional general permits. If any potential impacts are proposed, we can assist you with permitting options and support to complete the process. As part of the permitting process, we will conduct a preliminary review of state and federal agency records pertaining to Section 7 (Federal Endangered Species Act) and Section 106 (National Historic Preservation Act). If deemed necessary, we can assist you with targeted species surveys or cultural investigations to satisfy the requirements of the Nationwide Permit (NWP), Individual Permit (IP), or General Permit conditions. Section 404 of the Clean Water Act regulates the discharge of dredge and fill materials into waters of the United States (lakes, rivers, ponds, streams, etc.), including wetlands. Waters of the United States include territorial seas, navigable coastal and inland lakes, rivers, perennial streams, intermittent streams, and wetlands. The EPA and the U.S. Army Corps of Engineers jointly administer the Section 404 program. Section 401 of the Clean Water Act grants each state the authority to approve, condition, or deny any Federal permits that could result in a discharge to State waters. Mitigation and stormwater management plans will be a condition of permits issued for the Site. Buffers may be required adjacent to streams and water bodies. In North Carolina, compensatory mitigation at a minimum one-for-one ratio will be required for all wetland losses that exceed 1/10 (0.1)acre and for stream bed losses of 2/100 (0.02)acre. The USACE, however, will typically require mitigation at a 2:1 ratio. Mechanisms for providing compensatory mitigation under Section 404 of the Clean Water Act include mitigation banks, in-lieu fee programs, and permittee-responsible mitigation. • Mitigation Banks: sites, or a suite of sites, where resources (e.g., wetlands, streams, riparian areas) are restored, established, enhanced, and/or preserved for the purpose of providing compensatory mitigation for impacts authorized under USACE permits. In general, a mitigation bank sells compensatory mitigation credits to permittees whose obligation to provide compensatory mitigation is then transferred to the mitigation bank sponsor. Means of establishing the required number of mitigation credits to purchase varies state to state and between regulatory districts, but may entail estimating linear feet and/or acreage of impact and completing state-specific calculation worksheets. • Permittee-responsible Mitigation: enables a developer to create their own mitigation project to offset ecosystem loss when there are no eligible mitigation banks in a specific area. ECS Project#49:20775 Page 5 ff August 21, 2023 • In-lieu Fee Program: a program involving the restoration, establishment, enhancement, and/ or preservation of aquatic resources through funds paid to a governmental or non-profit natural resources management entity to satisfy compensatory mitigation requirements. To qualify for a general permit, a project must comply with all general, regional or case-specific conditions imposed by the USACE. If all applicable conditions of the general permit cannot be met, the prospective permittee may require authorization under an individual permit (IP). The following list provides examples of activities that may require an IP authorization (Please note: this list is not comprehensive): 1) the proposed cumulative impact to WoUS (i.e., jurisdictional wetlands, streams, lakes, ponds, etc.) is greater than 0.5 acre; 2) the proposed loss of stream bed is greater than 0.05 acre; or 3) the proposed activity will result in permanent impacts to WoUS located within the floodway or mapped 100-year FEMA floodplain. IP authorizations generally take 4 to 18 months to obtain, due to conditions that may arise during the USACE review and public comment period and additional permit requirements, which entail detailed habitat analyses, alternative site analysis, project justification, impact avoidance and minimization plans, and a mitigation plan. A subsequent Environmental Impact Statement may be required by the USACE, pursuant to the findings of these analyses and scale of impact. 5.0 WATERSHED CLASSIFICATION/BUFFER REQUIREMENTS Surface waters in North Carolina are assigned a primary classification by the NC DWR. Surface Water Classifications are designations applied to surface water bodies, such as streams, rivers and lakes, which define the best uses to be protected within these waters. According to the NC DWR's Find Your HUC in North Carolina webmap and NC Surface Water Classifications website, the PSA occurs in the 5.1 State Riparian Buffer Requirements The PSA occurs in the Upper Cape Fear River Basin. According to the NC Riparian Buffer Areas webmap, no regulated riparian buffer areas have been established by the NC DWR for the Cape Fear Watershed. 5.2 Local Buffer Requirements ECS contacted the Cumberland CountyPlanning Department to determine if mandatory vegetative buffers and/or riparian buffers are required for streams, wetlands, or other waters in Cumberland County. According to the Cumberland County Planning Department, there are additional riparian buffer requirements in addition to the state mandated rule. (A) A minimum one hundred-foot vegetative buffer is required for all new development activities that exceed the low density option; otherwise, a minimum thirty-foot vegetative buffer for development activities is required along all perennial waters indicated on the most ECS Project#49:20775 Page 6 August 21, 2023 recent versions of U.S.G.S. 1:24,000 (7.5 minute) scale topographic maps or as determined by local government studies. Desirable artificial streambank or shoreline stabilization is permitted. (B) No new development is allowed in the buffer except for water dependent structures, other structures such as flag poles and security lights which result in only diminutive increases in impervious area and public projects such as road crossings and greenways where no practical alternative exists. These activities should minimize built-upon surface area, direct runoff away from the surface waters and maximize the utilization of stormwater Best Management Practices. ECS recommends consultation with a civil engineer to determine if mandatory vegetative buffers and/ or regulated development(impervious surfaces)setbacks are required for the site in addition to those mentioned above. 6.0 CONCLUSIONS Three potentially jurisdictional wetland areas totaling approximately 1.08 acres, one potentially jurisdictional stream totaling approximately 1,072 linear feet (0.18 acre), and one potentially jurisdictional pond totaling approximately 1.83 acres were identified and delineated within the study area.The locations and boundaries of the potentially jurisdictional Waters are illustrated on the attached Waters of the U.S. Delineation Map (Appendix I, Figure 7). The findings summarized in this report represent our best professional judgment concerning the presence of potential jurisdictional aquatic resources in the PSA at the time of the study. These findings are only to be considered preliminary and are for planning purposes only, as they have not yet been verified by the regulatory agencies and are, therefore, subject to change pending their review. ECS cannot guarantee that field conditions and/or WoUS boundaries will not change over time. Prior to conducting construction-related activities onsite, ECS recommends requesting a Preliminary Jurisdictional Determination from the USACE for verification of these results to satisfy the requirements of Section 404 of The Clean Water Act (33 U.S.C. 1344). No earth-disturbing activities should be conducted within the PSA until a USACE Determination has been issued.

F&R's scope of services included the following: • Completion of five (5) soil test borings (B-1 through B-5) to depths ranging from 30 to 50 feet below the existing ground surface; • Preparation of typed Boring Logs and development of a Subsurface Profile; • Performance of geotechnical laboratory testing on representative soil samples; • Performing field electrical resistivity tests at two locations; • Performing corrosivity and laboratory thermal resistivity testing; • Performing a geotechnical engineering evaluation of the subsurface conditions with regard to their suitability for the proposed construction; • Preparation of this geotechnical report by professional engineers. 2.0 PROJECT INFORMATION 2.1 SITE LOCATION AND DESCRIPTION The project is located on the west side of Gillespie Street, approximately 250 feet south of the intersection of Gillespie Street and Sally Hill Circle in Fayetteville, North Carolina (See Figure 1 in Appendix I). The project site consists of an approximately 44-acre parcel of land that is identified with Parcel Identification Number (PIN) 0424-66-0123 according to information obtained from the Cumberland County GIS online database. Based on observations made during our site activities, the project site mostly consists of cleared former pastures on the northern half of the project site, and wooded land in the southern half of the site. Overhead power lines are present along the northeast property line of the project site and run in southeast to northwest direction. A pond is located in the western portion of the site. The pond appears to drain to a smaller pond to the south. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 1 r&R Based on the ground surface elevations obtained from Cumberland County topographic data,the project site slopes from the northeast towards the pond in the western portion of the site, from an approximate elevation of EL 190 to EL 150. 2.2 PROPOSED CONSTRUCTION The proposed development will involve the construction of rows of solar panels within the northern half of the parcel that will be aligned in an approximate north-south direction. Detailed information related to panel loading and foundation type was not provided. We anticipate the panels will be supported on driven piles embedded to depths roughly 5 to 10 feet below the existing ground surface. Equipment pads with switchboards and transformers is proposed to be located at the eastern side of the site adjacent to the proposed entrance drive. Information provided to F&R regarding the weight of equipment pads (mat loading) should not exceed a net allowable bearing capacity of 500 pounds per square foot (psf). F&R assumes that cut and fills of less than 3 feet will be required to establish site grades. 3.0 EXPLORATION AND LABORATORY TESTING PROCEDURES 3.1 SUBSURFACE EXPLORATION F&R advanced a total of five (5) soil test borings (B-1 to B-5) as part of this exploration at the approximate locations requested by Booth & Associates and as shown on the Boring Location Plan presented as Figure No. 2 in Appendix I. The test borings locations were established in the field by F&R using a hand-held GPS unit. Ground surface elevations at the boring locations were interpolated from Cumberland County GIS topographic information. Given these methods of determination, the boring locations and ground surface elevations should only be considered approximate. The test borings were advanced with a track-mounted drill rig using 2-1/4" inside diameter (I.D.) hollow stem augers for borehole stabilization. Representative soil samples were obtained using a standard, two-inch outside diameter (O.D.) split-barrel sampler in general accordance with ASTM D 1586, Penetration Test and Split-Barrel Sampling of Soils (Standard Penetration Test). McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 2 rAZ The number of blows required to drive the split barrel sampler three, consecutive 6-inch increments with an automatic hammer is recorded and the blows of the last two 6-inch increments are added to obtain the Standard Penetration Test (SPT) N-values representing the penetration resistance of the soil. Five (5) Standard Penetration Tests were collected within the top 10 feet and then at a nominal interval of approximately 5 feet thereafter. A representative portion of the soil was obtained from each SPT sample, sealed in an eight-ounce glass jar, labeled, and transported to our laboratory for final classification and analysis by a geotechnical engineer. The soil samples were classified in general accordance with the Unified Soil Classification System (USCS), using visual-manual identification procedures (ASTM D2488). A Boring Log for each test boring is presented in Appendix II. Groundwater level measurements were not attempted at the termination of drilling in the borings due to utilizing mud rotary drilling techniques. Borings B-3 and B-5 were backfilled immediately after drilling. Temporary piezometers were installed in borings B-1, B-2, and B-4 to facilitate the measurement of stabilized groundwater levels. The temporary piezometers consisted of 1-inch diameter, hand-slotted PVC pipe installed into the completed borings. Following the collection of the stabilized groundwater readings,the temporary piezometers were removed from the borings and all of the boreholes were backfilled with soil cuttings. 3.2 FIELD RESISTIVITY TESTING F&R also performed a field resistivity survey at the referenced project site at two locations selected by Booth &Associates (see Figure 2 in Appendix I).The resistivity testing was performed in general accordance with ASTM G57 by the Wenner 4-point method using a Megger DET 5/4D Digital Earth Tester. Resistance measurements were made at each test area using electrodes spaced approximately 2, 5, 10 and 40 feet. The results of the resistivity testing are presented in Appendix III. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 3 r&R 3.3 LABORATORY TESTING F&R selected two representative soil samples and subjected them to routine geotechnical index testing consisting of Natural Moisture Content, Sieve Analysis and Atterberg Limits determinations. The purpose of the index testing was to aid in our classification of the soil samples and development of engineering recommendations. The laboratory testing was performed in general accordance with applicable ASTM standards and are presented in Appendix III of this report. In addition to the geotechnical testing, thermal resistivity and corrosivity tests were also performed. The thermal resistivity/conductivity testing was performed in general accordance with ASTM D 5334. Two undisturbed Shelby tube samples and two five gallon bucket samples from the auger cuttings were collected at/near borings B-2 and B-4 from depths of 1 to 3.5 feet below the ground surface. Thermal resistivity tests were performed on bulk soil samples recompacted to 85% of the Modified Proctor and samples from the Shelby Tubes. The results of the thermal resistivity tests are presented in Appendix III. Three SPT jar soil samples were subjected to pH, chloride ion, soluble sulfates, electrical resistivity, redox potential, and sulfides testing to aid in assessing the corrosivity potential of the on-site soils as will be discussed in Section 4.4. The results of the corrosivity tests are presented in Appendix III. 4.0 REGIONAL GEOLOGY & SUBSURFACE CONDITIONS 4.1 REGIONAL GEOLOGY The project site is located in the Coastal Plain Physiographic Province of North Carolina.The near surface Coastal Plain soils have resulted from the deposition of sediments several million years ago during the period that the ocean receded from this area to its present location along the Atlantic Coast. The Coastal Plain Province is a broad flat plain with widely spaced low rolling hills where the near-surface soils have their origin from the deposition of sediments several million years ago during the period that the ocean receded from this area to its present location along McKim& Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 4 r&R the Atlantic Coast. It is noted that the Coastal Plain soils vary in thickness from only a few feet along the western border to over ten thousand feet in some areas along the coast. According to the Geologic Map of North Carolina (1985), the site is located in the Cape Fear Formation. The Cape Fear Formation is mapped as Cretaceous period marine deposits that are described as sandstone and sandy mudstone,yellowish gray to bluish gray, mottled red to yellowish orange, indurated, graded and laterally continuous bedding, blocky clay, faint cross-bedding, feldspar and mica common. 4.2 SUBSURFACE CONDITIONS 4.2.1 General The subsurface conditions discussed in the following paragraphs and those shown on the attached Boring Logs represent an estimate of the subsurface conditions based on an interpretation of the boring data using normally-accepted, geotechnical engineering judgments. Although individual soil test borings are representative of the subsurface conditions at the boring locations on the dates shown, they are not necessarily indicative of subsurface conditions at other locations or at other times. A subsurface profile has been prepared from the boring data to graphically illustrate the subsurface conditions encountered at the site.The subsurface profile is presented as Figure No. 3 in Appendix I. Strata breaks designated on the boring logs and subsurface profile represent approximate boundaries between soil types. The transition from one soil type to another may be gradual or occur between soil samples. More-detailed descriptions of the subsurface conditions at the individual boring locations are presented on the boring logs provided in Appendix II. 4.2.2 Surficial Materials Surficial Organic Soils were encountered at the surface of the borings, from the ground surface to a depth of 0.2 feet. The Surficial Organic Soils generally consisted of dark-colored soil material containing roots, fibrous matter, and/or other organic components, and is generally unsuitable for engineering purposes. F&R has not performed any laboratory testing to determine the organic McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 5 r&R content or other horticultural properties of the observed Surficial Organic Soil materials.Therefore, the term Surficial Organic Soil is not intended to indicate suitability for landscaping and/or other purposes.The Surficial Organic Soil depths provided in this report are based on driller observations and should be considered approximate. We note that the transition from Surficial Organic Soil to underlying materials may be gradual, and therefore the observation and measurement of the Surficial Organic Soil depths is subjective.Actual Surficial Organic Soil depths should be expected to vary. 4.2.3 Possible Fill Soils Possible Fill soils were encountered below the surficial soils in boring B-2 and extended to a depth of 3.5 feet below the existing ground surface. It is noted that sometimes the relatively small and disturbed sample obtained in the field is insufficient to definitively describe the origin of the subsurface material. Since man-made materials,deleterious materials, or other obvious evidence of fill were not encountered in the some of the soil samples, the materials believed to be earth fill are referred to as "possible fill". Based on a review of historical aerial images, it appears the existing possible fill materials are located in areas adjacent to historical agricultural fields. The possible fill soils consisted of moist, loose silty fine sand (SM) with SPT N-values ranging from 6 to 7 bpf. The possible fill soils appeared to contain trace amounts of roots. Possible fill soils exhibiting SPT N-values of 4 bpf or less are generally indicative of fill with poor compaction while fill soils exhibiting SPT N-values of 5 to 8 bpf are generally indicative of fill with moderate compaction. Well-compacted fill, that does not contain gravel, would typically exhibit SPT N-values of 9 bpf or higher. In general, it appears that the possible fill was moderately compacted. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 6 rAZ 4.2.4 Coastal Plain Soils Native coastal plain soils were encountered in all of the borings below the surficial organic and possible fill soils. The native soils typically consisted of very loose to very dense silty and clayey sands (USCS—SM and SC) with SPT N-values ranging from 2 to 79 bpf, and soft highly plastic clay (USCS—CH) with a SPT N-value of 4 bpf. Very loose sand layers were encountered in borings B-1, B-3, B-4, and B-5 at depths ranging from just below the existing ground surface to 3.5 feet below the existing ground surface. Deeper layers of very loose sand were encountered in borings B-3 and B-5 at depth of 38.5 and 28.5 feet, respectively, and extended to depths of 43.5 and 33.5 feet, respectively. A layer of soft, highly plastic clay(CH)was encountered in boring B-5 at a depth of 33.5 feet below the existing ground surface, and extended to the boring termination depth of 35 feet. 4.3 SOIL MOISTURE AND GROUNDWATER CONDITIONS Moist soils (i.e., within 3 percentage points of the estimated optimum moisture content) were encountered in all borings in the upper 2 to 8.5 feet of the soil profile. Wet or saturated soils (3 percentage points or greater over the estimated optimum moisture content) were encountered in the soil profile of all of the borings, at depths ranging from 2 to 8.5 feet below existing borings. Once encountered, these wet or saturated soils extended to the boring termination depths, with the exception of boring B-2, where the wet or saturated soils extended to a depth of 13.5 feet below the existing ground surface. A deeper layer of saturated soils were encountered in boring B-2 at a depth of 18.5 feet and extended to the boring termination depth of 30 feet. Groundwater level measurements were not attempted at the termination of drilling due to utilizing mud rotary techniques. Borings B-3 and B-5 were backfilled immediately after drilling. After a stabilization period of approximately 24-hours following completion of drilling,groundwater levels were measured in borings B-1, B-2, and B-4. Stabilized groundwater was encountered at depths ranging from 13.9 to 14.8 feet below the existing ground surface in these borings. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 7 rAZ It should be noted that the groundwater levels fluctuate depending upon seasonal factors such as precipitation and temperature. As such, soil moisture and groundwater conditions at other times may vary from those described in this report. F&R notes that due to the presence of relatively impervious silty and clayey soils, noted on the project site, trapped or perched water conditions may be encountered during periods of inclement weather and during seasonally wet periods. 4.4 SOIL CORROSIVITY EVALUATION Three soil samples were subjected to laboratory testing to determine pH, Chloride and Sulfate concentrations as well as Electrical Resistivity and Redox Potential. The results of the pH, Chloride, Sulfate, Sulfide, Electricity Resistivity and Redox Potential testing are presented in the following table: Boring Sample Moisture pH Chloride Sulfate Sulfides Electrical Redox Depth Content (mg/kg) (mg/kg) (mg/kg) Resistivity Potential (ft) (%) (ohm-cm) (mV) B-1 1-3.5 4.63 5.09 <262* <367* 34.8 3,850 255 B-2 1-3.5 2.21 4.97 <256* <358* <25.5* 2,490 263 B-4 1-3.5 3.42 5.00 <259* <362* <25.8* 4,460 286 *Below indicated method quantitation limit Corrosion potential of soils for underground structures is dependent upon several factors including pH, soil moisture, resistivity, sulfates and chlorides. It is F&R's opinion that the soils on this site appear to have a mild to moderate corrosion potential based on the slightly acidic pH readings, relatively low chloride and sulfate concentrations and moderately high resistivity. We are not aware of the existence of other corrosive factors such as coal, cinders, muck, peat, mine wastes, or landfills at this site, which may categorize the site as highly corrosive and negate the test results. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 8 r&R 5.0 PRELIMINARY GEOTECHNICAL DESIGN RECOMMENDATIONS 5.1 GENERAL The geotechnical engineering recommendations contained in this section of the report are based upon the results of the five soil test borings, the information provided regarding the proposed construction, and our familiarity with geotechnical engineering practices in this area. It is our opinion that the subsurface conditions encountered at the project site are suitable for the proposed construction from a geotechnical engineering perspective provided the recommendations presented in this report are followed throughout the design and construction phases of this project. F&R requests an opportunity to review project structural plans and specifications to confirm that the recommendations presented in this report have been properly interpreted and implemented, and to determine if additional geotechnical recommendations are warranted. Please contact F&R at your earliest convenience if you feel additional recommendations are warranted or if the recommendations in this report need additional clarification. 5.2 SOLAR PANEL FOUNDATION SUPPORT Details related to solar panel type,foundation type and design foundation loads are not available. We anticipate the proposed solar panels will be supported on deep foundation system i.e. driven piles. The piles should be designed to resist lateral and uplift forces. In order to assist in the foundation design, L-Pile deep foundation parameters have been provided in the following table.The L-Pile parameters are provided for the subsurface conditions encountered in the borings and represents an idealized subsurface profile. Please note that the tabulated values in Table 1 are for the given layered models with the understanding that the transitions between different soil strata are usually less distinct than those indicated in the table. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 9 r&R TABLE 1: L Pile Parameters L-Pile 5.0 Design Depth (feet) Total Unit Cohesive Parameters Friction Soil Type Weight Strength Static Soil Angle USCS Strain Top Bottom (pcf) (psf) Modulus,K (degrees) Eso (pci) 0 6.5 Silty Sand 115 - - 25 29 SM 6.5 13.5 Silty Sand 115 - - 25 29 SM 13.5 18.5 Clayey Sand 120 - - 60 33 SC 18.5 28.5 Silty Sand 115 - - 20 29 SM 28.5 35 Clayey Sand/Sandy Clay 110 300 0.02 25 28 SC/CH Notes: 1.All depths are from existing grade and should be adjusted based on the top of foundation elevation. 2.The soil parameters in the above tables are based on correlations with the SPT values. 5.3 EQUIPMENT PAD Foundation SUPPORT We understand that equipment pads will be installed for support of various control and monitoring equipment and transformers. F&R understands that the equipment slabs will consist of a reinforced 9-inch thick concrete slab supported by a layer of 1-foot thick washed stone or non-frost structural fill. F&R has been informed that the soil contact pressures generated by the loading on the mats would not exceed 500 psf. Due to the relatively light expected loading and the conditions encountered in boring B-1, settlements of the equipment pads are estimated to be on the order of 1 inch or less. We would expect that the settlements would be relatively uniform across a rigidly designed mat. Provided that the site preparation and fill placement recommendations presented in the subsequent sections of this report are followed, the proposed equipment pad area near B-1 is suitable to support the equipment pads. The magnitude of settlements will be influenced by the variation in excavation requirements across the along mat footprint, the distribution of loads, and the variability of underlying soil conditions. Our settlement analysis was performed on the basis of the provided structural loading at the time of this report. Actual settlements experienced by the structures and the time required for these soils to settle will be influenced by undetected variations in subsurface conditions, final grading McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 10 r&R plans,and the quality of fill placement and foundation construction. If the proposed structure loads are greater than indicated in earlier in this section or if there are additional mat foundations proposed that F&R has not been apprised of, please provide pertinent structural information for F&R to review and comment. For purposes of design, it is recommended that the mat design be based on a coefficient of subgrade reaction (K) of 13 pci. F&R recommends that the layer of non-frost structural fill extend at least 2 feet below exterior grades for frost and bearing capacity considerations. Final slab and reinforcing sizing should be determined by the Project Structural Engineer based on actual design loads, building code requirements and other structural considerations. 5.4 ACCESS ROAD DESIGN CONSIDERATIONS Due to the presence of some very loose surface soils, unstable subgrade conditions could develop along the access roadway alignment beneath construction equipment during removal of surficial organic soils. In order to help prevent unstable conditions from occurring, it is recommended that the surficial soils be stabilized prior to roadway grading by undercutting and replacing the very loose soils. F&R anticipates that the subgrade undercut/repair depths will be on the order of 12 to 18 inches. Additional repairs may be recommended at the time of construction. These repairs will be based upon actual field conditions observed by the geotechnical engineer and should be determined based upon proofrolling and/or other subgrade evaluations. If these evaluations reveal unstable conditions, the method of repair should be as directed by the project geotechnical engineer. Methods of repair may include, but are not necessarily limited to: drying and re-compaction; additional undercutting; application of lime; use of geotextiles; or other methods deemed appropriate by the project geotechnical engineer.Any necessary repairs should be made based upon actual field conditions observed by the geotechnical engineer at the time of construction, and should be determined based upon proofrolling and other subgrade evaluations. We have been informed that the first 50 feet of the entrance driveway will consist of asphalt pavement, with the remaining length being unpaved. The pavement structure should comply McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 11 rAZ with the minimum standards for roadways as required by the City of Fayetteville. Proofrolling of the pavement subgrades, placement of ABC base course and asphalt surface courses, should be observed, tested and approved by the project geotechnical engineer. Upon request, F&R would be pleased to provide a site specific pavement design in accordance with the City of Fayetteville requirements based on the actual soil subgrade strength testing(CBR tests) and estimated traffic volumes. However, a this time we believe a preliminary asphalt section consisting of 3 inches of 9.5B asphalt and 8 inches of compacted NCDOT ABC stone would likely be sufficient for the project. For the interior drives, it is anticipated that one light maintenance pickup truck will visit the site every day. For light maintenance traffic, we recommend an 8 inch layer of compacted ABC stone to be placed on the access road. Since the road will not be paved, we recommend a woven geo- textile (equivalent to Mirafi 500X) be installed on the subgrade prior to placement of the ABC stone. The subgrade should be confirmed to be stable prior to placement of the geo-textile. We emphasize that good drainage is essential for successful performance of the road. The access road should be maintained in a drained condition at all times.Water build-up in the gravel surface could saturate the underlying soils and result in softening of the subgrade and premature failures. Proper drainage may be aided by grading the site such that surface water is directed away from the road,and construction of swales adjacent to the road.The access road should be graded such that surface water is directed towards the outer limits of the road. 5.5 SITE SEISMIC CLASSIFICATION The following recommendations are based on the 2018 North Carolina Building Code (NCBC). Our scope of services did not include site specific soil shear wave velocity testing. F&R has evaluated the data obtained from the soil test borings for assignment of Seismic Site Class to this site. In accordance with procedures outlined in the 2018 NC Building Code for determining Site Class, a weighted average of the soil conditions in the upper 100 feet was performed using SPT N-values with the assumption that very dense/very hard soils are present below the maximum 50 foot McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 12 rAZ exploration depth. Based on this evaluation of the SPT N-values, the soil profile indicates a Site Class "E" is applicable to the project. It may be beneficial to consider performing shear wave testing to evaluate whether the site class may be upgraded to Site Class D if the upgrade would provide significant cost benefits to the project. Although F&R has not performed a liquefaction evaluation, it is F&R's opinion that there does not appear to be a potential for liquefaction due to the presence of moderate consistency silty and clayey sands that typically exist over most of the site within the depths of our exploration. In addition, the relatively high fines content of the finer grained clays encountered across the site also indicate that liquefaction is unlikely. If a detailed evaluation of liquefaction is desired, F&R would be available to perform such an evaluation at your request. 6.0 GEOTECHNICAL CONSTRUCTION RECOMMENDATIONS 6.1 SITE PREPARATION Initial site development should include stripping all surficial organic soils, roots, vegetation and any other deleterious materials from load bearing areas. The stripping should extend a distance of at least 5 feet beyond the building/foundation perimeters. Following the stripping operations, the exposed subgrade soils at the finished subgrade level and in fill sections should be proofrolled with a loaded tandem axle dump truck, scraper, or other similar type of construction equipment at the option of the geotechnical engineer to confirm the stability of the subgrade soils. The proofroll operations should be observed by a geotechnical engineer or his representative. If proofrolling reveals unstable conditions, the method of repair should be as directed by the project geotechnical engineer. Methods of repair may include, but are not necessarily limited to drying and re-compaction; undercutting and replacement with suitable structural fill; use of geo- textiles and/or geo-grids with select fill; use of lime stabilization; or other methods deemed appropriate by the project geotechnical engineer. Very loose soils were encountered within the upper 2 to 6.5 feet of the soil profile of the borings and as such, F&R anticipates that subgrade repairs may be required to establish stable subgrades across portions of the site. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 13 rAZ Wet to saturated soils conditions were encountered in the borings at depths ranging from 2 to 8.5 feet to termination depths of the borings. As such,the cut soils from mass grading operations and from utility trench excavations will likely be wet and require drying in order to be successfully used as compacted, structural fill and backfill. In addition, it is possible that relatively shallow perched and subsurface water could be encountered during construction depending upon the time of the year site grading is performed. Open ditches and/or interceptor drains may be required to improve site and soil profile drainage, improve soil moisture conditions, and help stabilize near surface conditions. 6.2 STRUCTURAL FILL PLACEMENT AND COMPACTION Below the surficial and existing possible fill soils, the on-site native near-surface soils that were encountered typically consisted of silty and clayey sands (SM and SC). These soils should be suitable for re-use as structural fill but may require drying to achieve adequate compaction and stability. Structural fill should have moisture contents within 2 to 3 percent of optimum moisture at the time of placement. If highly plastic soils (CH and MH) soils are encountered during site grading activities they should not be used as structural fill. Approved structural fill, not including NCDOT ABC stone, should consist of granular material or low plasticity (PI less than 15) silty and clayey sandy soils (SM and SC). If imported structural fill is required for the project,the fill should be approved by the geotechnical engineer prior to these materials being transported to the site.All structural fill should be within 2 to 3 percentage points of optimum moisture content at the time of placement. Structural fill should be placed in lifts not to exceed 6 to 8 inches and compacted to at least 95 percent of the Standard Proctor (ASTM D-698) maximum dry density. The top 12 inches of subgrades in all load bearing building and pavement areas should be compacted to at least 98 percent of the Standard Proctor (ASTM D-698) maximum dry density. Utility trench backfill in load bearing areas should be compacted to at least 95 percent of the Standard Proctor (ASTM D- 698) maximum dry density. Fill and backfill materials placed in non-load bearing areas (e.g., non- McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 14 rAZ vehicular grassed areas)areas should be compacted to at least 92 percent of the Standard Proctor (ASTM D-698) maximum dry density. Monitoring of all site preparation including stripping, undercutting and backfilling operations; fabric/stabilization material placement; and density testing on each lift of backfill to verify that adequate compaction is being achieved should be performed by a qualified soils technician working under the direct supervision of the geotechnical engineer. Depending upon the cut depths and site conditions at the time of construction, some soils may require moisture conditioning (i.e., drying of wet soils, or wetting of dry soils) prior to use as structural fill. As such, it is recommended that earthwork be performed during the summer and early fall months (mid-April through November) when the weather conditions are more conducive to moisture conditioning of soils. As previously stated, the on-site soils have sufficient silt/clay content to render them moisture sensitive. The on-site soils will become unstable (i.e., pump and rut) during normal construction activities when in the presence of excess moisture. Soils with a moisture content greater than 3 percentage points above the optimum moisture content are generally considered to have excessive moisture. During earthwork and construction activities, surface-water runoff should be drained away from construction areas to prevent water from ponding on or saturating the soils within excavations or on subgrades. 6.3 EQUIPMENT PAD FOUNDATION CONSTRUCTION RECOMMENDATIONS We recommend that all foundation subgrades and bearing grades be observed by a qualified geotechnical engineer or their representative prior to placement of reinforcing steel and concrete. The purpose of the engineering observation would be to determine that the foundations bear in suitable soils at the proper embedment depths, and that unsuitable soft or loose materials are undercut and backfilled with approved structural fill material. Hand auguring and Dynamic Cone Penetrometer (DCP) testing should be performed at the direction of the project geotechnical engineer to verify the consistency of the subgrade soils and underlying support soils. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 15 r&R It is recommended that a smooth bladed backhoe bucket be used to remove the final 6 to 12 inches of soils above the subgrade in order to prevent disturbing soils below the subgrade and/or prevent gouging narrow grooves in the subgrade as may occur with a toothed-end bucket. If soft, very loose, or otherwise unsuitable soils are encountered at the subgrade elevation, undercutting and repair may be required. If undercutting is performed,the undercut excavations should be backfilled with materials approved by the project geotechnical engineer. We anticipate that most undercuts can be backfilled with clean sands (less than 10 percent fines), NCDOT ABC stone, and/or No. 57 washed stone up to the planned subgrade. If ABC stone is utilized, it may be placed in 12 inch thick lifts and compacted to at least 95 percent of the Standard Proctor maximum dry density (ASTM D-698). If clean sand is used, it may be placed in a single 8 to 12 inch thick lifts and compacted to at least 95 percent of the Standard Proctor maximum dry density(ASTM D-698).The washed stone thickness should not exceed 2 feet before the surface of the washed stone is densified with a heavy vibratory plate compactor to the satisfaction of the geotechnical engineer or their representative. In some circumstances, the geotechnical engineer may recommend that the undercuts be backfilled with lean concrete or flowable fill. Exposure to the environment may weaken the soils at the subgrade level if excavations remain open for long periods of time. The subgrade surface should be level or suitably benched and free of loose soil, ponded water, and debris. If the subgrade soils are softened by surface water intrusion or exposure,the softened soils must be removed from the excavation immediately prior to placement of concrete. Excavations must be maintained in a drained/de-watered condition throughout the foundation construction process. If the foundation excavations must remain open overnight,or if rainfall becomes imminent while the subgrade soils are exposed,we strongly recommend that a 2 to 3 inch thick "mud mat" of lean concrete (2,000 psi) be placed on the subgrade before placing the reinforcing steel. In addition, F&R stresses the need for positive perimeter surface drainage around structure areas to direct all runoff water away from structures and foundations. McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 16 rAZ 6.4 PAVEMENT CONSTRUCTION RECOMMENDATIONS Pavement subgrades should be prepared as outlined in previous sections of this report. All base course stone beneath flexible pavement should be compacted to at least 100 percent of the modified Proctor maximum dry density (ASTM D-1557). We emphasize that good base course drainage is essential for successful pavement performance. The ABC stone should be maintained in a drained condition at all times. Water build-up in the base course could result in premature pavement failures. Proper drainage may be aided by grading the site such that surface water is directed away from pavements and construction of swales adjacent to pavements. All pavements should be graded such that surface water is directed towards the outer limits of the paved area or to catch basins located such that surface water does not remain on the pavement. Flexible asphalt pavements and bases should be constructed in accordance with the guidelines of the latest applicable NCDOT Standard Specifications for Roads and Structures. Materials, weather limitations, placement and compaction are specified under appropriate sections of this publication. 6.5 TEMPORARY EXCAVATION RECOMMENDATIONS We anticipate that the excavations at some locations may not be able to be sufficiently sloped and may require temporary shoring. Trench boxes or internally-braced excavations are anticipated; however, the type of excavation stabilization or shoring system used should be selected and designed by the contractor. Mass excavations and other excavations required for construction of this project must be performed in accordance with the United States Department of Labor, Occupational Safety and Health Administration (OSHA) guidelines (29 CFR 1926, Subpart P, Excavations) or other applicable jurisdictional codes for permissible temporary side-slope ratios and/or shoring requirements. The OSHA guidelines require daily inspections of excavations, adjacent areas and protective systems by a "competent person" for evidence of situations that could result in cave- McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 17 rAZ ins, indications of failure of a protective system, or other hazardous conditions. All excavated soils, equipment, building supplies, etc., should be placed away from the edges of excavations at a distance equaling or exceeding the depth of the excavation. F&R cautions that the actual excavation slopes will need to be evaluated frequently each day by the "competent person" and flatter slopes or the use of shoring may be required to maintain a safe excavation depending upon excavation-specific circumstances. The contractor is responsible for providing the "competent person" and all aspects of site excavation safety. F&R can evaluate specific excavation slope situations if we are informed and requested by the owner, designer, or contractor's "competent person". 7.0 CONTINUATION OF SERVICES As previously discussed, a geotechnical engineer should be retained to monitor and test earthwork activities, and observe subgrade preparations for foundations and pavements. It should be noted that the actual soil conditions at the various subgrade levels and footing bearing grades will vary across this site and thus the presence of the geotechnical engineer and/or their representative during construction will serve to validate the subsurface conditions and recommendations presented in this report. A geotechnical engineer should be employed to monitor the earthwork,foundation construction, and pile testing performed by others and to report that the recommendations contained in this report are completed in a satisfactory manner. The continued geotechnical engineering involvement on the project will aid in the proper implementation of the recommendations discussed herein. The following is a recommended scope of services: • Review of project plans and construction specifications to verify that the recommendations presented in this report have been properly interpreted and implemented; • Observe the earthwork process to document that subsurface conditions encountered during construction are consistent with the conditions anticipated in this report; • Observe the subgrade conditions before placing structural fill including proofroll observations; • Observe the placement and compaction of any structural fill and backfill,and perform laboratory and field compaction testing of the fill; McKim&Creed Gillespie Solar Farm F&R Project No. 668-0122 Revised:October 16,2023 18 rAZ • Observe the installation and testing of piles for the solar panel support systems; and, • Observe all foundation excavations and footing bearing grades for compliance with the recommended design soil bearing capacity. We also stress the importance of conducting hand auger and DCP testing at and extending several feet below the footing bearing grade in order to give an indication of the anticipated subsurface conditions and define footings that should be undercut and repaired as outlined in this report. 8.0 LIMITATIONS This report has been prepared for the exclusive use of McKim & Creed and/or their agents, for specific application to the referenced project in accordance with generally-accepted soil and foundation engineering practices. No other warranty, express or implied, is made. Our evaluations and recommendations are based on design information furnished to us;the data obtained from the previously-described, subsurface exploration program, and generally-accepted geotechnical engineering practice.The evaluations and recommendations do not reflect variations in subsurface conditions,which could exist intermediate of the boring locations or in unexplored areas of the site. There are important limitations to this and all geotechnical studies. Some of these limitations are discussed in the information prepared by GBA, which is included in Appendix IV. We ask that you please review this information. Regardless of the thoroughness of a subsurface exploration, there is the possibility that conditions between borings will differ from those at the boring locations,that conditions are not as anticipated by the designers, or that the construction process has altered the soil conditions. Therefore, experienced geotechnical engineers should evaluate earthwork, pavement, and foundation construction to verify that the conditions anticipated in design actually exist. Otherwise,we assume no responsibility for construction compliance with the design concepts, specifications, or recommendations.

They highlight soil limitations that affect various land uses and provide information about the properties of the soils in the survey areas. Soil surveys are designed for many different users, including farmers, ranchers, foresters, agronomists, urban planners, community officials, engineers, developers, builders, and home buyers. Also, conservationists, teachers, students, and specialists in recreation, waste disposal, and pollution control can use the surveys to help them understand, protect, or enhance the environment. Various land use regulations of Federal, State, and local governments may impose special restrictions on land use or land treatment. Soil surveys identify soil properties that are used in making various land use or land treatment decisions. The information is intended to help the land users identify and reduce the effects of soil limitations on various land uses. The landowner or user is responsible for identifying and complying with existing laws and regulations. Although soil survey information can be used for general farm, local, and wider area planning, onsite investigation is needed to supplement this information in some cases. Examples include soil quality assessments (http://www.nrcs.usda.gov/wps/ portal/nrcs/main/soils/health/) and certain conservation and engineering applications. For more detailed information, contact your local USDA Service Center (https://offices.sc.egov.usda.gov/locator/app?agency=nrcs)or your NRCS State Soil Scientist(http://www.nres.usda.gov/wps/portal/nres/detail/soils/contactus/? cid=nrcs142p2_053951). Great differences in soil properties can occur within short distances. Some soils are seasonally wet or subject to flooding. Some are too unstable to be used as a foundation for buildings or roads. Clayey or wet soils are poorly suited to use as septic tank absorption fields. A high water table makes a soil poorly suited to basements or underground installations. The National Cooperative Soil Survey is a joint effort of the United States Department of Agriculture and other Federal agencies, State agencies including the Agricultural Experiment Stations, and local agencies. The Natural Resources Conservation Service (NRCS) has leadership for the Federal part of the National Cooperative Soil Survey. Information about soils is updated periodically. Updated information is available through the NRCS Web Soil Survey, the site for official soil survey information.

They include a description of the soils and miscellaneous areas and their location on the landscape and tables that show soil properties and limitations affecting various uses. Soil scientists observed the steepness, length, and shape of the slopes; the general pattern of drainage; the kinds of crops and native plants; and the kinds of bedrock. They observed and described many soil profiles. A soil profile is the sequence of natural layers, or horizons, in a soil. The profile extends from the surface down into the unconsolidated material in which the soil formed or from the surface down to bedrock. The unconsolidated material is devoid of roots and other living organisms and has not been changed by other biological activity. Currently, soils are mapped according to the boundaries of major land resource areas (MLRAs). MLRAs are geographically associated land resource units that share common characteristics related to physiography, geology, climate, water resources, soils, biological resources, and land uses (USDA, 2006). Soil survey areas typically consist of parts of one or more MLRA. The soils and miscellaneous areas in a survey area occur in an orderly pattern that is related to the geology, landforms, relief, climate, and natural vegetation of the area. Each kind of soil and miscellaneous area is associated with a particular kind of landform or with a segment of the landform. By observing the soils and miscellaneous areas in the survey area and relating their position to specific segments of the landform, a soil scientist develops a concept, or model, of how they were formed. Thus, during mapping, this model enables the soil scientist to predict with a considerable degree of accuracy the kind of soil or miscellaneous area at a specific location on the landscape. Commonly, individual soils on the landscape merge into one another as their characteristics gradually change. To construct an accurate soil map, however, soil scientists must determine the boundaries between the soils. They can observe only a limited number of soil profiles. Nevertheless, these observations, supplemented by an understanding of the soil-vegetation-landscape relationship, are sufficient to verify predictions of the kinds of soil in an area and to determine the boundaries. Soil scientists recorded the characteristics of the soil profiles that they studied. They noted soil color, texture, size and shape of soil aggregates, kind and amount of rock fragments, distribution of plant roots, reaction, and other features that enable them to identify soils. After describing the soils in the survey area and determining their properties, the soil scientists assigned the soils to taxonomic classes (units). Taxonomic classes are concepts. Each taxonomic class has a set of soil characteristics with precisely defined limits. The classes are used as a basis for comparison to classify soils systematically. Soil taxonomy, the system of taxonomic classification used in the United States, is based mainly on the kind and character of soil properties and the arrangement of horizons within the profile. After the soil 5 Custom Soil Resource Report scientists classified and named the soils in the survey area, they compared the individual soils with similar soils in the same taxonomic class in other areas so that they could confirm data and assemble additional data based on experience and research. The objective of soil mapping is not to delineate pure map unit components; the objective is to separate the landscape into landforms or landform segments that have similar use and management requirements. Each map unit is defined by a unique combination of soil components and/or miscellaneous areas in predictable proportions. Some components may be highly contrasting to the other components of the map unit. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The delineation of such landforms and landform segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, onsite investigation is needed to define and locate the soils and miscellaneous areas. Soil scientists make many field observations in the process of producing a soil map. The frequency of observation is dependent upon several factors, including scale of mapping, intensity of mapping, design of map units, complexity of the landscape, and experience of the soil scientist. Observations are made to test and refine the soil-landscape model and predictions and to verify the classification of the soils at specific locations. Once the soil-landscape model is refined, a significantly smaller number of measurements of individual soil properties are made and recorded. These measurements may include field measurements, such as those for color, depth to bedrock, and texture, and laboratory measurements, such as those for content of sand, silt, clay, salt, and other components. Properties of each soil typically vary from one point to another across the landscape. Observations for map unit components are aggregated to develop ranges of characteristics for the components. The aggregated values are presented. Direct measurements do not exist for every property presented for every map unit component. Values for some properties are estimated from combinations of other properties. While a soil survey is in progress, samples of some of the soils in the area generally are collected for laboratory analyses and for engineering tests. Soil scientists interpret the data from these analyses and tests as well as the field-observed characteristics and the soil properties to determine the expected behavior of the soils under different uses. Interpretations for all of the soils are field tested through observation of the soils in different uses and under different levels of management. Some interpretations are modified to fit local conditions, and some new interpretations are developed to meet local needs. Data are assembled from other sources, such as research information, production records, and field experience of specialists. For example, data on crop yields under defined levels of management are assembled from farm records and from field or plot experiments on the same kinds of soil. Predictions about soil behavior are based not only on soil properties but also on such variables as climate and biological activity. Soil conditions are predictable over long periods of time, but they are not predictable from year to year. For example, soil scientists can predict with a fairly high degree of accuracy that a given soil will have a high water table within certain depths in most years, but they cannot predict that a high water table will always be at a specific level in the soil on a specific date. After soil scientists located and identified the significant natural bodies of soil in the survey area, they drew the boundaries of these bodies on aerial photographs and 6 Custom Soil Resource Report identified each as a specific map unit. Aerial photographs show trees, buildings, fields, roads, and rivers, all of which help in locating boundaries accurately. 7 Soil Map The soil map section includes the soil map for the defined area of interest, a list of soil map units on the map and extent of each map unit, and cartographic symbols displayed on the map. Also presented are various metadata about data used to produce the map, and a description of each soil map unit. 8 Custom Soil Resource Report Soil Map (Gillespie - B1.9 Solar Utility Station) M t 690200 690290 690380 690470 690560 690650 690740 34°58'42"N . • y / 34°58'42"N 00- ft Y L �� Ic �� _... i 4.k - g3 • F e ' . 4\ ' i^ \, '• � 4 M `4.

The map unit descriptions, along with the maps, can be used to determine the composition and properties of a unit. A map unit delineation on a soil map represents an area dominated by one or more major kinds of soil or miscellaneous areas. A map unit is identified and named according to the taxonomic classification of the dominant soils. Within a taxonomic class there are precisely defined limits for the properties of the soils. On the landscape, however, the soils are natural phenomena, and they have the characteristic variability of all natural phenomena. Thus, the range of some observed properties may extend beyond the limits defined for a taxonomic class. Areas of soils of a single taxonomic class rarely, if ever, can be mapped without including areas of other taxonomic classes. Consequently, every map unit is made up of the soils or miscellaneous areas for which it is named and some minor components that belong to taxonomic classes other than those of the major soils. Most minor soils have properties similar to those of the dominant soil or soils in the map unit, and thus they do not affect use and management. These are called noncontrasting, or similar, components. They may or may not be mentioned in a particular map unit description. Other minor components, however, have properties and behavioral characteristics divergent enough to affect use or to require different management. These are called contrasting, or dissimilar, components. They generally are in small areas and could not be mapped separately because of the scale used. Some small areas of strongly contrasting soils or miscellaneous areas are identified by a special symbol on the maps. If included in the database for a given area, the contrasting minor components are identified in the map unit 11 Custom Soil Resource Report descriptions along with some characteristics of each. A few areas of minor components may not have been observed, and consequently they are not mentioned in the descriptions, especially where the pattern was so complex that it was impractical to make enough observations to identify all the soils and miscellaneous areas on the landscape. The presence of minor components in a map unit in no way diminishes the usefulness or accuracy of the data. The objective of mapping is not to delineate pure taxonomic classes but rather to separate the landscape into landforms or landform segments that have similar use and management requirements. The delineation of such segments on the map provides sufficient information for the development of resource plans. If intensive use of small areas is planned, however, onsite investigation is needed to define and locate the soils and miscellaneous areas. An identifying symbol precedes the map unit name in the map unit descriptions. Each description includes general facts about the unit and gives important soil properties and qualities. Soils that have profiles that are almost alike make up a soil series. Except for differences in texture of the surface layer, all the soils of a series have major horizons that are similar in composition, thickness, and arrangement. Soils of one series can differ in texture of the surface layer, slope, stoniness, salinity, degree of erosion, and other characteristics that affect their use. On the basis of such differences, a soil series is divided into soil phases. Most of the areas shown on the detailed soil maps are phases of soil series. The name of a soil phase commonly indicates a feature that affects use or management. For example, Alpha silt loam, 0 to 2 percent slopes, is a phase of the Alpha series. Some map units are made up of two or more major soils or miscellaneous areas. These map units are complexes, associations, or undifferentiated groups. A complex consists of two or more soils or miscellaneous areas in such an intricate pattern or in such small areas that they cannot be shown separately on the maps. The pattern and proportion of the soils or miscellaneous areas are somewhat similar in all areas. Alpha-Beta complex, 0 to 6 percent slopes, is an example. An association is made up of two or more geographically associated soils or miscellaneous areas that are shown as one unit on the maps. Because of present or anticipated uses of the map units in the survey area, it was not considered practical or necessary to map the soils or miscellaneous areas separately. The pattern and relative proportion of the soils or miscellaneous areas are somewhat similar. Alpha-Beta association, 0 to 2 percent slopes, is an example. An undifferentiated group is made up of two or more soils or miscellaneous areas that could be mapped individually but are mapped as one unit because similar interpretations can be made for use and management. The pattern and proportion of the soils or miscellaneous areas in a mapped area are not uniform. An area can be made up of only one of the major soils or miscellaneous areas, or it can be made up of all of them. Alpha and Beta soils, 0 to 2 percent slopes, is an example. Some surveys include miscellaneous areas. Such areas have little or no soil material and support little or no vegetation. Rock outcrop is an example. 12 Custom Soil Resource Report Cumberland County, North Carolina BaB—Blaney loamy sand, 2 to 8 percent slopes Map Unit Setting National map unit symbol: w6z2 Elevation: 160 to 660 feet Mean annual precipitation: 38 to 52 inches Mean annual air temperature: 61 to 70 degrees F Frost-free period: 210 to 245 days Farmland classification: Farmland of statewide importance Map Unit Composition Blaney and similar soils: 90 percent Estimates are based on observations, descriptions, and transects of the mapunit.
