Eggering, PWS PARSONS 530 Maryville Centre Drive Suite 400 St. Louis, Missouri 63141 Rocky Mount-Wilson Reqional Airport (RWI) - Introduction Rocky Mount "Eagle" Airport, was established on July 2, 1930 by the Eagle Aircraft Company. The earliest airfield directory entry which has been located for Eagle Airport was in The Airport Directory Company's 1933 Airports Directory, and it described Eagle Airport as a commercial field located '/z mile north of Rocky Mount. The airfield was said to consist of a 4-acre rectangular sand & sod field, measuring 1,400' by 1,200'. Hangars & buildings were said to be located along the southeast side The airport was renamed Rocky Mount Municipal Airport at some point between 1934 and 1936 [https://krwiairport.com/history/]. Today the Rocky Mount-Wilson Regional Airport is owned and operated by the Rocky Mount-Wilson Regional Airport Authority and is located approximately 12 miles from the central business district of Rocky Mount, North Carolina and approximately 10 miles from the central business district of Wilson, North Carolina. �ocl� Mour�■��I�an ��Q�� .��■ �� The purpose of this study was to examine the potential for impacts to waters of the U.S., especially streams and wetlands, that could be affected by the Runway 4 Medium-Intensity Approach Lighting System (MALRS) Replacement and Localizer Relocation. Rocky Mount-Wilson Airport Page 1 Soils Information - Soil Map Units on or Adlacent to Rocky Mount-Wilson Airport [Adapted from: Soil Survey of Nash County, North Carolina. U.S. Department of Agriculture, Soil Conservation Service. September 1989 (NRCS 1989)] Based upon the referenced soil survey for Nash County, the soils on the Rocky Mount-Wilson Airport that was surveyed the Localizer Relocation were Norfolk loamy sand, 2-6 percent slopes (NoB); Rains fine sandy loam, 0-2 percent slopes (RaA); and Urban Land (uR). The soils affected for the MALSR Replacement were Urban Land (uR); Rains fine sandy loam, 0-2 percent slopes (RaA); and Norfolk loamy sand, 0-2 percent slopes (NoA). The soils data is shown on Table 1 and on Figure 1 below. Table 1. Rocky Mount-Wilson Airport Project - Nash County Soils.

Ur-Urban land. This map unit consists of areas 85 percent of which are covered with streets, buildings, parking lots, railroad yards, and an airport. The natural soils were greatly altered by cutting, farming, grading, and shaping during the processes of urban development. The original landscape, topography, and commonly the drainage patterns have been changed. The areas between facilities are used as parks, lawns, playgrounds, cemeteries, and drainageways. Most of the soils have altered by cutting and filling. Most of the acreage of this map unit is around Rocky Mount and some of the towns in the county, but isolated areas are throughout the county. Slope is commonly 0 to 5 percent. Runoff is excessive on Urban land and increases the hazard of flooding in low-lying areas. Most of the soils on Rocky Mount-Wilson Airport are urban land. The excessive runoff to adjacent wetlands facilitates the wetland hydrology. NoA-Norfolk loamy sand, 0 to 2 percent slopes. This soil is well-drained and nearly level. It is on broad interstream divides of Coastal Plain uplands. Some of the larger areas of this soil are in vicinity of the Hickory community. The mapped areas range from 3 to 500 acres. Typically, the surface layer is grayish brown loamy sand about 10 inches thick. The subsurface Rocky Mount-Wilson Airport Page 2 layer is very pale brown sandy loam to a depth of about 19 inches. The subsoil extends to a depth of at least 82 inches. It is brownish yellow sandy clay loam in the upper part. The middle part is brownish yellow sandy clay loam that has yellowish red and very pale brown mottles, and the lower part is mottled brownish yellow, yellow, red, and gray sandy foam. Norfolk soil has slow surface runoff. Permeability is moderate, and the available water capacity is high. This soil is susceptible to plowpan formation where the topsoil thickness is more than the plow depth. Wind erosion is a hazard if the soil is not protected. A seasonal high water table is 48 to 60 inches below the surface during January to March. NoB-Norfolk loamy sand, 2 to 6 percent slopes. This soil is well-drained and gently sloping. It is on convex ridges and side slopes of the Coastal Plain uplands. Some larger areas of this soil are in the vicinity of Strickland's Crossroads. Some areas in the Piedmont section of the county are 5 to 25 acres. Typically, the surface layer is grayish brown loamy sand about 10 inches thick. The subsurface layer is very pale brown sandy loam to a depth of about 19 inches. The subsoil extends to a depth of at least 79 inches. It is brownish yellow sandy clay loam in the upper part. The middle part is brownish yellow sandy clay loam that has yellowish red and very pale brown mottles, and the lower part is mottled brownish yellow, yellow, red, and gray sandy loam. Norfolk soil has moderate surface runoff. Permeability is moderate, and the available water capacity is high. This soil is susceptible to erosion, if left unprotected. Plowpans develop where the topsoil thickness is more than the plow depth. A seasonal high-water table is 48 to 60 inches below the surFace in January to March. Ra-Rains fine sandy loam. This soil is poorly drained and nearly level. It is on the lowest landscape position of broad, smooth uplands of the Coastal Plain and in the depressions of dissected landscapes throughout the county. Some larger areas of this soil are in the vicinity of Sharpsburg. The mapped areas range from 3 to 600 acres. Typically, the surface layer is very dark gray fine sandy loam about 6 inches thick. The subsurface layer is light brownish gray loam to a depth of 11 inches. The subsoil extends to a depth of at least 85 inches. Rains soils have a high water table at or near the surface during all but the driest times of the year. Permeability and water capacity are moderate. All of the wetland data points occurred in the mapped sections of RaA. Rocky Mount-Wilson Airport Page 3 Figure 1.

Weil'and - � Stream � 750 1,54t� 3,00� Feet S�il Map UniQ Rocky Mount-Wilson Airport Page 4 Climate Climate affects the physical, chemical, and biological relationship in the soil, mainly through the influence of precipitation and temperature. Water dissolves minerals, is necessary for biological activity, and transports minerals and organic residue through the soil profile. The amount of water that actually percolates through the soil is dependent mainly on the amount and duration of rainfall, relative humidity, evapotranspiration, length of the frost-free period, and soil characteristics. Temperature influences the kind and growth of organisms and the speed of physical and chemical reaction in the soils. The climate of Nash County is warm and humid. Precipitation is well distributed. The relatively mild temperatures and the abundant moisture cause rapid decomposition of organic matter and speed up chemical reactions in the soil. The high rainfall leaches out large amounts of soluble bases, and less soluble, fine materials are moved deeper in the soil. The average annual rainfall is approximately 44.5 inches, and the average annual growing season is approximately 225 days (NRCS 1989). Vegetation Summary The vegetation in the effected portion of the Rocky Mount-Wilson Airport has been altered over time during the construction of the airport and through routine maintenance mowing and likely herbicide applications. It is evident that all voluntary trees are mowed or chemically treated to ensure that all of the safe zones are maintained. Natural succession to a forested plant community cannot occur on the site. Most of the airport is impervious surfaces or mowed/maintained turf grasses. Within the small depressions and drainageways, herbaceous plants that can tolerate mowing and other disturbance have become established. A diversity of plants can be seen in the small areas that were too wet to mow within the current growing season with various sedges, grasses, and broadleaf plants. For the MALSR area southwest of Hornes Road, some natural vegetation has become established, however, the area is frequently maintained. The area at the most southern portion of the MALSR area is an organic farming operation that was tilled and was primarily devoid of natural vegetation. Hydrology Summary With an average precipitation rate of over 44.5 inches of rain per year combined with the extensive impervious surfaces in the airport, the primary hydrology for the area is from direct precipitation and runoff. The small depressional wetlands and drainageways appear to remain saturated and/or inundated for extended periods during the growing season. The seasonally high water table also affects the areas hydrology and soils. Evidence in some areas includes the equipment ruts from mowing equipment and unmowed vegetation likely due to the excessively wet conditions. The Northeast Wetland by the localizer access road may also receive some infrequent backwater flooding from the Tar River Reservoir, which could contribute to the hydrology of this wetland. The area immediately southwest of Hornes Road appears to be connected to a much larger wetland/swamp that extends toward the south. It is unlikely that the Tar River Reservoir flooding affects the hydrology of this area as there does not appear to be a direct connection in a floodway/floodplain. Rocky Mount-Wilson Airport Page 5 Wetlands and Surface Water Survey The specific objective of the wetland and surface water survey was to identify potential wetlands and other waters of the U.S. occurring within and immediately adjacent to the affected portions of the Rocky Mount-Wilson Airport that may be impacted by the proposed Runway 4 MALRS Replacement and Localizer Relocation and to characterize the wetland resources in terms of wetland type, size, and functional value. The USACE, under Section 404 of the CWA, regulates WOUS, including jurisdictional wetlands and streams. The U.S. Environmental Protection Agency (EPA) and USACE have promulgated a number of regulations to implement the permitting program. Section 401 of the CWA provides the state authority to issue certification that a proposed dredge and fill disposal activities will not violate applicable state water quality standards. Part 230.10(a)(5)(b) of the Guidelines states that no discharge of dredged or fill material shall be permitted if it "causes or contributes, after consideration of disposal site dilution and dispersion, to violations of any applicable state quality standards." A Section 401 certification (or waiver) is required for any discharge regulated under Section 404. The USACE defines wetlands as: Those areas that are inundated or saturated by surface water or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions (33 CFR Part 328.3b). Wetlands have hydrophytic vegetation, hydric soils, and occur in areas that are permanently or periodically inundated or saturated with water. Wetlands generally include swamps, marshes, bogs and similar areas. Based upon USACE and EPA regulatory guidance following recent court cases, to be considered jurisdictional, a wetland area must be adjacent to other WOUS or display a level of connectivity to the local watershed and satisfy criteria for hydrology, hydric soils, and hydrophytic vegetation (SWANC 2001, Rapanos, 2006). Wetland hydrology means that water permanently or periodically inundates soils or that the soil is saturated to the surface for a given duration during the growing season. Hydric soils show signs of reduced rather than oxidized soil conditions. Hydrophytic plants have adapted to areas having hydric soils or to areas that have inundated or saturated soils, which create anaerobic conditions. Wetlands are defined by the USACE as "areas that are inundated or saturated by surface or ground water 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" (USACE, 1987). Section 404 of the Clean Water Act extends authorization to the USACE to regulate activities that affect waters of the U.S., including wetlands. The USACE issues Section 404 permits for the discharge of dredged or fill material into wetlands and other waters of the U.S. The USACE has the authority to determine the jurisdictional status of waters of the U.S., including wetlands. Significant nexus. The term significant nexus means that a water, including wetlands, either alone or in combination with other similarly situated waters in the region (i.e., the watershed that drains to the nearest water of the U.S.), significantly affects the chemical, physical, or biological integrity of a regulated water. For an effect to be significant, it must be more than speculative or insubstantial. Other waters, including wetlands, are similarly situated when they perform similar Rocky Mount-Wilson Airport Page 6 functions and are located sufficiently close together or sufficiently close to a"water of the U.S." so that they can be evaluated as a single landscape unit with regard to their effect on the chemical, physical, or biological integrity of a regulated water. Potential wetlands were preliminarily identified within the study area by reviewing existing U.S. Geological Survey (USGS) topographic maps, Natural Resources Conservation Service (NRCS) soil survey maps, U.S. Fish and Wildlife Service (USFWS) National Wetlands Inventory (NWI) maps, and aerial photographs. Field surveys were conducted to confirm the presence or absence of wetlands within the southern portion of the Rocky Mount-Wilson Airport that could be impacted by the proposed access road relocation/improvement. Wetland delineations were made January 24, 2018 utilizing the technique as described in the USACE Wetlands Delineation Manual (USACE, 1987) and the Regional Supplement to the Corps of Engineers Wetland Delineation manual: Atlantic and Gulf Coastal Plain Region (version 2) (AGCP Region, 2010). The USACE three-parameter approach (hydrology, soils, and vegetation) was applied to make routine wetlands determinations in the field. This approach requires an on-site inspection of the vegetative composition, soils, and hydrology of an area to make wetland determinations. At least one positive wetland indicator for each parameter must be evident for a positive wetland determination. General diagnostic characteristics for each parameter distinguish wetlands from non-wetland or upland areas. These characteristics are described below for each parameter (USACE, 1987 and AGCP Region, 2012). Wetland vegetation generally consists of macrophytes that are typically adapted to areas that are at least periodically inundated or saturated by surface or groundwater. These hydrophytic species, due to morphological, physiological, and/or reproductive adaptations, have the ability to grow, compete, reproduce, and/or persist in anaerobic soil conditions, which develop in wetland soils due to inundation or prolonged saturation. Indicators of hydrophytic vegetation include more than 50 percent of the dominant plant species having a regional indicator status of obligate wetland (OBL), facultative wetland (FACW), or facultative (FAC). In addition, morphological plant adaptations, such as buttressed trunks, adventitious roots, and floating leaves, are also considered indications of hydrophytic vegetation. Wetland soils are classified as hydric or possess characteristics that are associated with reducing soil conditions. Indicators of hydric soils include presence of organic soils (peats or mucks), histic epipedons, sulfidic materials, gleyed soils, soils with distinct mottles and/or low chroma matrix, and presence of iron and manganese concretions, among others. Wetland hydrology is defined by an area that is inundated either permanently or periodically at mean water depths less than or equal to 6.6 feet, or the soil is saturated to the surface at some time during the growing season creating reducing soil conditions. Indicators of wetland hydrology include, but are not limited to, the presence of drainage patterns, sediment deposition, water marks, and visual observations of inundation or saturation. Rocky Mount-Wilson Airport Page 7 Summary Description of Rocky Mount-Wilson Airport Wetlands A walking survey of the project area was completed on January 24, 2018. Figure 2 illustrates the wetlands that were identified during the survey. Figures 3 and 4 show the wetland boundaries in relation to the proposed facilities. There were small areas in the project limits that were delineated as wetlands, the Northeast Wetland, the Southwest Runway Depression, MALSR Wetland, and the Farmed Wetland. A summary of wetland features is shown on Table 2. The Northeast Wetland is >2.0-acre wet meadow that remains saturated for long durations during the growing season. The >1.0-acre Southwest Runway Depression extends from just south of the runway fill to just south of the south boundary fence. This wet meadow is bisected by access/maintenance roads which are slightly raised on fill. The >2.0-acre MALSR Wetland is a scrub-shrub drainage swale that ponds water for long durations during the growing season. The >1.0-acre Farmed Wetland is likely connected to the MALSR Wetland outside of the study limits of this project. It is a wet drainage swale that appears to remain saturated for long durations of the growing season, however it is tilled and appears to be farmed annually. There is a small ephemeral channel that drained from the northeast end of Runway 4 past the existing localizer shelter towards the northeast. This ephemeral channel empties into the Northeast Wetland, and it appears to be manmade. This ephemeral channel would likely be considered a wet weather conveyance, and it contributes to the hydrology of the Northeast Wetland. The ephemeral channel is not directly affected by the project. The wetlands on the airport property would likely be considered jurisdictional, because they are adjacent to the wetlands and streams that enter the Tar River Reservoir. A total of >5.0 acres of wetland were delineated near the project area on the Rocky Mount- Wilson Airport. As shown on Table 2, the proposed facilities (i.e. Relocated Localizer and MALSR Replacement) would impact approximately 0.19 acres of Wetlands in total in the Northeast Wetland, Southwest Runway Wetland, MALSR Wetland, and Farmed Wetland. The primary hydrology for the Rocky Mount-Wilson Airport wetlands appears to be from stormwater runoff from the runway and adjacent uplands and a seasonally high-water table as discussed in the Nash County Sil Survey. Stormwater flows from these uplands into the depressions and low-lying areas which is absorbed by the moderately permeable sandy loam soils. There are minor areas of ponding, and filamentous algae was evident in the inundated portions of the depressions, which was evidence of prolonged inundation. Vegetation on the Rocky Mount-Wilson Airport consists of maintained/mowed turf grasses. However, there is a slight change in the vegetation communities in the wet meadows/depressions as sedges (Carex spp.), spike rushes (Eleocharis spp.), barnyard grass (Echinochloa crusgalli), and paspalum (Paspalum laeve) are dominant. Outside of the depression, more upland species including grease grass (Tridens flavus), fescue (Festuca spp. and bluegrass (Poa pratensis) become dominant. Rocky Mount-Wilson Airport Page 8 Rains soils have a high water table at or near the surface during all but the driest times of the year. Permeability and water capacity are moderate. All of the wetland data points occurred in the mapped sections of RaA. For permitting purposes, Nationwide Permit No. 14 (Linear Transportation Projects) would likely be applicable for the access road to the relocated localizer and Nationwide Permit No. 12 (Utility Line Activities) would be used for the replacement of the MALSR facilities. A Pre-Construction Notification (PCN) to the District Engineer will be prepared, because there will be a minor amount of fill (less than 0.22 acres) in four special aquatic sites (wetlands).
