Three Oaks Engineering (Three Oaks) was contracted to conduct a habitat assessment for federally protected bat species for R-5840. The proposed roadway improvements may affect structures that could provide bat roosting habitat. The project study area (PSA) for this survey was the same as that used for the Natural Resources Technical Report (NCDOT 2017). See Figure 1. The Northern Long-eared Bat (Myotisseptentrionalis, MYSE) and Tricolored Bat (Perimyotissubflavus, PESU) are listed by the U.S. Fish and Wildlife Service (USFWS) as potentially occurring in the PSA (Appendix C). The Little Brown Bat (Myotis lucifugus, MYLU), which may become federally listed in the future, may also be found in Polk County. 2.0 METHODS The habitat assessment and structure inspections followed the guidance set forth by the USFWS Range - wide Indiana Bat & Northern Long-eared Bat Survey Guidelines (USFWS 2024). NCDOT Bat Habitat Assessment Forms for bridges, culverts, and abandoned structures were completed as specified in the Standard Operating Procedures (NCDOT 2024). All surveys performed were consistent with the protocols stipulated in the USFWS National White -Nose Syndrome Decontamination Protocol (White - nose Syndrome Disease Management Working Group 2024). No mist -net surveys were conducted. Spatial data containing records for active and inactive mine locations were obtained from the U.S. Geological Survey (USGS), Mineral Resources On -Line Spatial Data website (USGS 2024). The project footprint was compared to the mine database to check for mine locations within a half -mile of the project. There are no mines within a half -mile of the PSA. Field inspections were performed on May 29, 2024. Any bridges or abandoned structures in the PSA were visually inspected during daylight hours by trained, experienced biologists. Any culverts at least 3 ft in diameter and 60 ft long were inspected. Coordinates were obtained for all surveyed structures. Photos were taken of any bridges, culverts, or structures that had evidence of bat use in the PSA. 3.0 FINDINGS Forested areas with trees large enough for roosting (>3 inches in diameter at breast height [DBH]) were found along the PSA. Few dead snags or trees with flakey bark or crevices were observed. No caves were observed in the PSA. Only one culvert at least 3 ft in diameter and 60 ft long was located within the PSA; remaining culverts were shorter than 45 ft in length. No abandoned buildings were located in the PSA. Four bridges were present and were surveyed. One of these bridges, NC 9 over US 74, was only partially in the PSA; however, the entire bridge was surveyed. The bridge had evidence of bats in the form of vocalizations and fresh guano. Bats were heard roosting in both deck expansion joints. In addition, two adult Mexican Free -tailed Bats (Tadarida brasiliensis) were observed in a guard rail crevice and one deceased juvenile Mexican Free -tailed Bat was observed on the side of a pier cap. All guano observed at June 2024 R-5840 Federally Protected Bat Survey NC 9, Polk County, NC the bridge was small in size. The colony size was estimated to be at least 20-100 bats. No evidence of bats was observed at any other structure. A list of inspected structures is provided in Table 1. See Figure 2 for locations. Field inspection data forms are provided in Appendix A, and photos are in Appendix B. Table 1.

Suitable summer habitat for the MYSE is generally characterized as forested areas with trees larger than three inches DBH. Summer roost sites include tree cavities or crevices, loose bark of live or dead trees, bridges, and abandoned buildings. According to the North Carolina Natural Heritage Program (NCNHP 2024) Biotics Database, the nearest MYSE element occurrence (EO) is approximately 8 miles west of the PSA, last observed in 1990 (EO ID # 32138, historical occurrence). A more recent occurrence is located approximately 9.5 miles northwest of the project, dating from 2005 (EO 32158). NOTE: According to the unofficial IPaC report, this species only needs to be considered if the project includes wind turbine operations (Appendix C). Tricolored Bat (Perimyotis subflavus; PESU) The PESU is proposed as a federally endangered species. They are generally associated with forested landscapes. In summer, they will roost in tree foliage, or sometimes in buildings. They are also known to roost in bridges and culverts. The nearest PESU occurrence is 7.5 miles southwest of the PSA, last observed in 2022 (NCNHP 2024, EO ID # 42749). Little Brown Bat (Myotis lucifugus; MYLU) The MYLU is under review by the USFWS for federal listing. This species will readily use man-made structures such as buildings and bridges for roosting. The nearest MYLU occurrence is located 19 miles northeast of the project, last observed in 2012 (NCNHP 2024, EO ID # 35332). No caves, mines or rock outcrops were observed in the project study area. There is likely no suitable winter habitat for MYSE or MYLU due to the lack of caves and mines in the PSA. It is possible that the single culvert greater than 60 ft in length (structure 1) could provide suitable winter habitat for PESU.

IPaC Resource List 15 June 2024 IPaC U.S. Fish & Wildlife Service IPaC resource list This report is an automatically generated list of species and other resources such as critical habitat (collectively referred to as trust resources) under the U.S. Fish and Wildlife Service's (USFWS) jurisdiction that are known or expected to be on or near the project area referenced below. The list may also include trust resources that occur outside of the project area, but that could potentially be directly or indirectly affected by activities in the project area. However, determining the likelihood and extent of effects a project may have on trust resources typically requires gathering additional site -specific (e.g., vegetation/species surveys) and project -specific (e.g., magnitude and timing of proposed activities) information. Below is a summary of the project information you provided and contact information for the USFWS office(s) with jurisdiction in the defined project area. Please read the introduction to each section that follows (Endangered Species, Migratory Birds, USFWS Facilities, and NWI Wetlands) for additional information applicable to the trust resources addressed in that section.

Additional areas of influence (AOI) for species are also considered. An AOI includes areas outside of the species range if the species could be indirectly affected by activities in that area (e.g., placing a dam upstream of a fish population even if that fish does not occur at the dam site, may indirectly impact the species by reducing or eliminating water flow downstream). Because species can move, and site conditions can change, the species on this list are not guaranteed to be found on or near the project area. To fully determine any potential effects to species, additional site -specific and project -specific information is often required. Section 7 of the Endangered Species Act requires Federal agencies to "request of the Secretary information whether any species which is listed or proposed to be listed may be present in the area of such proposed action" for any project that is conducted, permitted, funded, ❑r licensed by any Federal agency. A letter from the local office and a species list which fulfills this requirement can only be obtained by requesting an official species list from either the Regulatory Review section in IPaC (see directions below) or from the local field office directly. For project evaluations that require USFWS concurrence/review, please return to the IPaC website and request an official species list by doing the following: 1. Draw the project location and click CONTINUE. 2. Click DEFINE PROJECT. 3. Log in (if directed to d❑ so). 4. Provide a name and description for your project. S. Click REQUEST SPECIES LIST.

Probability of Presence( ) Each green bar represents the bird's relative probability of presence in the 10km grid cells) your project overlaps during a particular week of the year. (A year is represented as 12 4- week months.) A taller bar indicates a higher probability of species presence. The survey effort (see below) can be used to establish a level of confidence in the presence score. One can have higher confidence in the presence score if the corresponding survey effort is also high. How is the probability of presence score calculated? The calculation is done in three steps: 1. The probability of presence for each week is calculated as the number of survey events in the week where the species was detected divided by the total number of survey events for that week. For example, if in week 12 there were 20 survey events and the Spotted Towhee was found in 5 of them, the probability of presence of the Spotted Towhee in week 12 is 0.25. 2. To properly present the pattern of presence across the year, the relative probability of presence is calculated. This is the probability of presence divided by the maximum probability of presence across all weeks. For example, imagine the probability of presence in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12 (0.25) is the maximum of any week of the year. The relative probability of presence on week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2. 3. The relative probability of presence calculated in the previous step undergoes a statistical conversion so that all possible values fall between 0 and 10, inclusive. This is the probability of presence score. To see a bar's probability of presence score, simply hover your mouse cursor over the bar. Breeding Season ( Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across its entire range. If there are no yellow bars shown for a bird, it does not breed in your project area. Survey Effort (1) Vertical black lines superimposed on probability of presence bars indicate the number of surveys performed for that species in the 10km grid cell(s) your project area overlaps. The number of surveys is expressed as a range, for example, 33 to 54 surveys. To see a bar's survey effort range, simply hover your mouse cursor over the bar. No Data (—) A week is marked as having no data if there were no survey events for that week.

Nationwide Conservation Measures describes measures that can help avoid and minimize impacts to all birds at any location year round. Implementation of these measures is particularly important when birds are most likely to occur in the project area. When birds may be breeding in the area, identifying the locations of any active nests and avoiding their destruction is a very helpful impact minimization measure. To see when birds are most likely to occur and be breeding in your project area, view the Probability of Presence Summary. Additional measures or permits may be advisable depending on the type of activity you are conducting and the type of infrastructure or bird species present on your project site. What does IPaC use to generate the list of migratory birds that potentially occur in my specified location? The Migratory Bird Resource List is comprised of USFWS Birds of Conservation Concern (BCC)• and other species that may warrant special attention in your project location. The migratory bird list generated for your project is derived from data provided by the Avian Knowledge Network (AKN). The AKN data is based on a growing collection of survey, banding, and citizen science datasets and is queried and filtered to return a list of those birds reported as occurring in the 1Okm grid cell(s) which your project intersects, and that have been identified as warranting special attention because they are a BCC species in that area, an eagle (Eagle Act requirements may apply), ❑r a species that has a particular vulnerability to offshore activities or development. Again, the Migratory Bird Resource list includes only a subset of birds that may occur in your project area. It is not representative of all birds that may occur in your project area. To get a list of all birds potentially present in your project area, please visit the Rapid Avian Information Locator (RAIL) Tool. What does IPaC use to generate the probability of presence graphs for the migratory birds potentially occurring in my specified location? The probability of presence graphs associated with your migratory bird list are based on data provided by the Avian Knowledge Network (AKN). This data is derived from a growing collection of survey., banding, and citizen science datasets. Probability of presence data is continuously being updated as new and better information becomes available. To learn more about how the probability of presence graphs are produced and how to interpret them, go the Probability of Presence Summary and then click on the "Tell me about these graphs" link. How do I know if a bird is breeding, wintering or migrating in my area? To see what part of a particular bird's range your project area falls within (i.e. breeding, wintering, migrating or year-round), you may query your location using the RAIL Tool and look at the range maps provided for birds in your area at the bottom of the profiles provided for each bird in your results. If a bird on your migratory bird species list has a breeding season associated with it, if that bird does occur in your project area, there may be nests present at some point within the timeframe specified. If "Breeds elsewhere" is indicated, then the bird likely does not breed in your project area. What are the levels of concern for migratory birds? Migratory birds delivered through IPaC fall into the following distinct categories of concern: 1, "BCC Rangewide" birds are Birds of Conservation Concern (BCC) that are of concern throughout their range anywhere within the USA (including Hawaii, the Pacific Islands, Puerto Rico, and the Virgin Islands); 2. "BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation Regions (BCRs) in the continental USA; and 3. "Nan -BCC - Vulnerable" birds are not BCC species in your project area, but appear on your list either because of the Eagle Act requirements (for eagles) or (for non -eagles) potential susceptibilities in offshore areas from certain types of development or activities (e.g. offshore energy development or longline fishing). Although it is important to try to avoid and minimize impacts to all birds, efforts should be made, in particular, to avoid and minimize impacts to the birds on this list, especially eagles and BCC species of rangewide concern. For more information on conservation measures you can implement to help avoid and minimize migratory bird impacts and requirements for eagles, please see the FAQs for these topics. Details about birds that are potentially affected by offshore projects For additional details about the relative occurrence and abundance of both individual bird species and groups of bird species within your project area off the Atlantic Coast, please visit the Northeast Ocean Data Portal. The Portal also offers data and information about other taxa besides birds that may be helpful to you in your project review. Alternately, you may download the bird model results files underlying the portal maps through the NOAA NCCOS Integrative Statistical Modeling and Predictive Mapping of Marine Bird Distributions and Abundance on the Atlantic Outer Continental Shelf project webpage. Bird tracking data can also provide additional details about occurrence and habitat use throughout the year, including migration. Models relying on survey data may not include this information. For additional information on marine bird tracking data, see the Diving Bird Study and the nanotag studies or contact Caleb Spiegel or Pam Loring. What if I have eagles on my list? If your project has the potential to disturb or kill eagles, you may need to obtain a permit to avoid violating the Eagle Act should such impacts occur. Proper Interpretation and Use of Your Migratory Bird Report The migratory bird list generated is not a list of all birds in your project area, only a subset of birds of priority concern. To learn more about how your list is generated, and see options for identifying what other birds may be in your project area, please see the FAQ "What does IPaC use to generate the migratory birds potentially occurring in my specified location". Please be aware this report provides the "probability of presence" of birds within the 10 km grid cell(s) that overlap your project; not your exact project footprint. On the graphs provided, please also look carefully at the survey effort (indicated by the black vertical bar) and for the existence of the "no data" indicator (a red horizontal bar). A high survey effort is the key component. If the survey effort is high, then the probability of presence score can be viewed as more dependable. In contrast, a low survey effort bar or no data bar means a lack of data and, therefore, a lack of certainty about presence of the species. This list is not perfect; it is simply a starting point for identifying what birds of concern have the potential to be in your project area, when they might be there, and if they might be breeding (which means nests might be present). The list helps you know what to look for to confirm presence, and helps guide you in knowing when to implement conservation measures to avoid or minimize potential impacts from your project activities, should presence be confirmed. To learn more about conservation measures, visit the FAQ "Tell me about conservation measures I can implement to avoid or minimize impacts to migratory birds" at the bottom of your migratory bird trust resources page.

Wetlands in the National Wetlands Inventory (NWI) Impacts to NWI wetlands and other aquatic habitats may be subject to regulation under Section 404 of the Clean Water Act, or other State/Federal statutes. For more information please contact the Regulatory Program of the local U.S. Army Corps of Engineers District. Please note that the NWI data being shown may be out of date. We are currently working to update our NWI data set. We recommend you verify these results with a site visit to determine the actual extent of wetlands on site. This location overlaps the following wetlands: FRESHWATER FORESTED/SHRUB WETLAND PSS1 A PSS1 Ax I:] i'J MWkVJTJAJ I I:J If] 119] PUBHh PUBHx 1: R2UBH R3UBH RSUBH R4SBC 00 ?*AP IC-00 1.� A full description for each wetland code can be found at the National Wetlands Inventory website NOTE: This initial screening does not replace an on -site delineation to determine whether wetlands occur. Additional information on the NWI data is provided below. Data limitations The Service's objective of mapping wetlands and deepwater habitats is to produce reconnaissance level information on the location, type and size of these resources. The maps are prepared from the analysis of high altitude imagery. Wetlands are identified based on vegetation, visible hydrology and geography. A margin of error is inherent in the use of imagery; thus, detailed on -the -ground inspection of any particular site may result in revision of the wetland boundaries or classification established through image analysis. The accuracy of image interpretation depends on the quality of the imagery, the experience of the image analysts, the amount and quality of the collateral data and the amount of ground truth verification work conducted. Metadata should be consulted to determine the date of the source imagery used and any mapping problems. Wetlands or other mapped features may have changed since the date of the imagery or field work. There may be occasional differences in polygon boundaries or classifications between the information depicted on the map and the actual conditions on site. Data exclusions Certain wetland habitats are excluded from the National mapping program because of the limitations of aerial imagery as the primary data source used to detect wetlands. These habitats include seagrasses or submerged aquatic vegetation that are found in the intertidal and subtidal zones of estuaries and nearshore coastal waters. Some deepwater reef communities (coral or tuberficid worm reefs) have also been excluded from the inventory. These habitats, because of their depth, go undetected by aerial imagery. Data precautions Federal, state, and local regulatory agencies with jurisdiction over wetlands may define and describe wetlands in a different manner than that used in this inventory. There is no attempt, in either the design or products of this inventory, to define the limits of proprietaryjurisdiction of any Federal, state, ❑r local government or to establish the geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities involving modifications within or adjacent to wetland areas should seek the advice of appropriate Federal, state, or local agencies concerning specified agency regulatory programs and proprietary jurisdictions that may affect such activities. o�
