Subject:Protected Species Habitat Assessment Report
Mt Holly Pumping Station and Force Main
Charlotte, North Carolina
CWS Project No. 2019-0368

Dear Mr. Osborne,

Carolina Wetland Services, Inc. (CWS) has been contracted to provide a protected species
habitat assessment for the Mt Holly Pumping Station and Force Main site. The Mt Holly
Pumping Station and Force Main study area is approximately 55 acres in extent and is located
in both Mount Holly in Gaston County and unincorporated Mecklenburg County, North Carolina
(Figure 1).

Methods
In-office Desktop Review
To determine which protected species are listed as occurring or potentially occurring within the
project vicinity and prior to conducting the on-site field investigation, CWS consulted the United
States Fish and Wildlife Service’s (USFWS) Endangered and Threatened Species and Species
of Concern by County for North Carolina online database for Mecklenburg County and Gaston 1
County . In addition, CWS performed a data review using the North Carolina Natural Heritage 2
Program (NCNHP) Data Explorer on November 19, 2019 to determine if any record 3
occurrences of federally-listed, candidate endangered, threatened species, or critical habitat are
located within the project limits.

Typical habitat requirements for listed species was discerned from multiple USFWS and 4
NCNHP online resources including, but not limited to, specific USFWS species profiles, 5

of Agriculture - Natural Resources Conservation Service (USDA-NRCS) Web Soil Survey of
Mecklenburg and Gaston Counties and aerial imagery were also reviewed for potential habitat 6
communities of listed species within the project vicinity (Figures 2 and 3).

Field Survey
CWS scientists Dan Zurlo, Project Scientist, Julia McGuire, Staff Scientist II, and Ian Dunning,
Staff Scientist I, conducted a pedestrian habitat assessment of the project area on November 7
and November 19, 2019. Potential habitat for potentially occurring federally-protected species
that was identified during the desktop review was assessed in the field for the quality of physical
and/or biological features essential to the conservation of the applicable species. Additionally,
during the pedestrian habitat assessment, areas were reviewed for applicable federally
protected species; however, formal surveys were not conducted. An off-site population of
Schweinitiz’s sunflower identified in the previous EA document for the site and NCNHP report 7
was located. Its location is depicted in Figure 3. Identification references for natural
communities include Schafale and Weakley’s Third Approximation for Natural Communities of
North Carolina (1990) and Weakley (2015) for plant species. 8 9

Results
Based on the previous EA document​7​ and NCNHP data explorer review, there is one current
record of Schweinitz's sunflower within the project limits, and within a mile of the project limits
(Attachment A). The USFWS lists eight federally protected species for Mecklenburg and
Gaston Counties (Table 1). An official species list has not been obtained from the USFWS
Asheville Field Office.

Two terrestrial community types were identified within the project area during the field survey.
These community types consist of mixed forest and herbaceous areas (Figure 3). Of the
identified on-site community types, both the mixed forest and herbaceous areas are considered
potential habitat for federally threatened or endangered species that could potentially occur
within the project limits. Aquatic habitat is present on-site in the form of one perennial stream.
A brief description of each species habitat requirements and determination of effect findings are
listed below by species.

Schweinitz’s sunflower (​Helianthus schweinitzii​)
Habitat Description:
Schweinitz’s sunflower is a perennial herb with yellow rays and yellow centers. They
can reach heights of five feet. Populations are limited to the piedmont of North and
South Carolina. It has been listed as an endangered species under the Endangered
Species Act (ESA) since 1991. The typical habitat for this plant includes roadsides, old 10
pastures, transmission line right-of-ways, open areas, either natural or
human-maintained habitats, or edges of upland woods. Major characteristics of soils
associated with suitable Schweinitz’s sunflower habitat include thin soils, soils on upland
interstream flats or gentle slopes, soils that are clay like in both composition and texture
(and often with substantial rock fragments), soils that have a high shrinkage swell
capacity, and those which vary over the course of the year from very wet to very dry.

Biological Analysis:
The previous EA document and NCNHP data record review revealed one current 11
occurrence for this species within the project limits (Attachment A). The desktop review
determined that herbaceous areas could be potential habitat for Schweinitz's sunflower,
but the forested areas do not receive the appropriate amount of sunlight for the
sunflower due to a heavy canopy (Photograph 1). While most on-site herbaceous areas
are too intensively maintained to support Schweinitz's sunflower populations
(Photograph 2), one herbaceous area receives the appropriate amount of maintenance
through periodic mowing (Photograph 5). The documented population of Schweinitz's
sunflower individuals was located just off-site the project limits, to the north of the site
(six ramets; Figure 3, Photograph 4). The project area was scrutinized during the
November 7 and November 19, 2019 site visits, and no Schweinitz's sunflower
individuals or individuals of any ​Helianthus ​species were observed within the project
area. ​As no Helianthus species were observed on-site, CWS concludes that this
project will have no effect on the Schweinitz’s sunflower.

Michaux’s sumac (​Rhus michauxii​)
Habitat Description:

Michaux’s sumac is a rhizomatous shrub. It is densely hairy with compound leaves
exhibiting evenly-serrated leaflets. Flowers are small, greenish to white, in terminal
clusters. Fruits are red drupes produced from August to October. It has been listed as
an Endangered species under the ESA since 1989. It is found on the coastal plains of 12
Virginia to Florida, with most populations occurring in North Carolina. It prefers sandy or
rocky open woods with basic loam soils, as well as highway right-of-ways, roadsides, or
edges of artificially-maintained clearings.

Biological Analysis:
A NCNHP data record review revealed that there are no current occurrences for this
species within the project limits or within a one-mile radius of the project (Attachment A).
Open areas conducive to early-succession species were observed within the project
area. However, no individuals of Michaux sumac were observed during the field
assessment on November 7 and November 19, 2019. Additionally, there are no current
records of this species within Mecklenburg County . Michaux sumac is not listed in 13
Gaston County. ​Due to the lack of observations for this species within the study
area and known current occurrences within Gaston and Mecklenburg Counties,
CWS concludes that this project will have no effect on the Michaux’s sumac.

Dwarf-flowered heartleaf (​Hexastylis naniflora​)
Habitat Description:
Dwarf-flowered heartleaf is endemic to the western Piedmont and foothills of North and
South Carolina. This herbaceous evergreen is found in moist to dry forests along bluffs;
boggy areas next to streams and creek heads; and adjacent hillsides, slopes, and
ravines. Requiring acidic, sandy loam soils, the species is found in soil series such as
Pacolet, Madison, and Musella, among others. Occurrences are generally found on a
north-facing slope. Undisturbed natural communities such as Piedmont/Coastal Plain
Heath Bluff, Dry-Mesic Oak Hickory Forest, and Mesic Mixed Hardwood Forest hold the
most viable occurrences. However, less viable remnant occurrences are found in
disturbed habitats, including logged, grazed, mown, and residential/commercial
developed lands; areas converted to pasture, orchards, and tree plantations; roadside
right-of-ways; and on upland slopes surrounding man-made ponds or lakes. 14

Biological Analysis:
A NCNHP data record review revealed that there are no current occurrences for this
species within the project limits, or within a one-mile radius of the project. Of the on-site
habitat types, only the forested areas could be potential habitat for this species. The
desktop review revealed that the project area does not contain the soils associated with
the dwarf-flowered heartleaf. The hillsides assessed for the presence of potential
habitats were densely vegetated in the herbaceous layer, which is not conducive to
dwarf-flowered heartleaf (Photograph 1). Species commonly associated with the
dwarf-flowered heartleaf, such as mountain-laurel (​Kalmia latifolia​), were not found

on-site. Due to the lack of suitable habitat and lack of known occurrences in the project
vicinity, ​CWS concludes that the project will have no effect on the dwarf-flowered
heartleaf.

Smooth purple coneflower (​Echinacea laevigata​)
Habitat Description:
Smooth purple coneflower is a tall, perennial herbaceous plant found in areas with
abundant sunlight where competition in the herbaceous layer is minimal. It has been
federally listed as Endangered under the ESA since 1992. Typical habitat for this plant 15
includes meadows, open woodlands, the ecotonal regions between meadows and
woodlands, cedar barrens, dry limestone bluffs, clear cuts, and roadside and utility
rights-of-way. In North Carolina, the species normally grows in magnesium- and calcium-
rich soils associated with gabbro and diabase parent material, and typically occurs in
Iredell, Misenheimer, Mecklenburg, and Picture soil series. It grows best where there is
abundant sunlight, little competition in the herbaceous layer, and periodic disturbances
(e.g., regular fire regime, well-timed mowing, careful clearing) that prevents
encroachment of shade-producing woody shrubs and trees. On sites where woody
succession is held in check, it is characterized by a number of species with prairie
affinities.

Biological Analysis:
A NCNHP data record review revealed that there are no current occurrences for this
species within the project limits or within a one-mile radius of the project (Attachment A).
Potential on-site habitat is limited to the infrequently maintained on-site herbaceous
areas. These infrequently maintained areas do not occur in areas with Iredell,
Misenheimer, Mecklenburg, or Picture soil series. Additionally, no individuals of smooth
purple coneflower were observed during the field assessment on November 7 and
November 19, 2019. ​Due to the lack of suitable habitat and observed individuals,
this project will have no effect on the smooth coneflower.

Carolina heelsplitter (​Lasmigona decorata​)
Habitat Description:
The Carolina heelsplitter was historically known from several locations within the
Catawba and Pee Dee River systems in North Carolina and the Pee Dee and Savannah
River systems, and possibly the Saluda River system in South Carolina. In North
Carolina, the species is now known only from a handful of streams in the Pee Dee and
Catawba River systems. The species exists in very low abundances, usually within 6 feet
of shorelines, throughout its known range. The general habitat requirements for the
Carolina heelsplitter are shaded areas in large rivers to small streams, often burrowed
into clay banks between the root systems of trees, or in runs along steep banks with
moderate current. Recently, the Carolina heelsplitter has been found is in sections of 16

streams containing bedrock with perpendicular crevices filled with sand and gravel, and
with wide riparian buffers. 17

Biological Analysis:
A desktop review of potential on-site habitat for the Carolina heelsplitter was conducted
on the on-site perennial stream during the site visits on November 7 and November 19,
2019. The on-site perennial streams have silty banks and moderate amounts of woody
debris (Photograph 3). These stream conditions are not considered supportive Carolina
heelsplitter habitat.

The Catena Group surveyed the study area for freshwater mussels in 2008 and no
Carolina heelsplitter individual were found. The report concluded that Carolina
heelsplitters were not likely to occur within the study area due to the degraded conditions
of the stream. After reviewing the site, CWS concludes that the conditions have not
improved since the 2008 survey documented in the previous EA document . Based on 18
the lack of potential habitat, previous mussel surveys, and the NCNHP database
indicating there is no known population of the species within one-mile of the project area,
CWS concludes that this project will have no effect on the Carolina heelsplitter.

Rusty Patched Bumble Bee (Bombus affinis)
The Rusty patched bumble bee was listed as Endangered under the ESA in January 2016. 19
Rusty patched bumble bees once occupied grasslands and tallgrass prairies of the Upper
Midwest and Northeast, but most grasslands and prairies have been lost, degraded, or
fragmented by conversion to other uses. According to USFWS guidance, the rusty patched
bumble bee population has declined by approximately 90% or more. There are currently
records of ​Bombus affinis​ in isolated places within 13 states and 1 providence since 2000. In
these areas, surveys should only be completed by qualified biologists under the guidance of the
federal recovery/scientific permit under section 10(a)(1)(B) of the ESA. These surveyors must
also meet all applicable state permitting and reporting requirements. The presence of ​Bombus
affinis​ has been broken down into three zones. A high potential zone provides a reasonable
basis for describing where the species is likely to be present and where federal agencies and
others should consult with Fish and Wildlife Services to evaluate the potential effects of their
actions. A low potential zone buffers a high potential zone and are much less likely to support
existing populations. Scientists are hopeful that some of these low potential areas may contain
the bee, and they recommend that surveyors obtain a scientific recovery permit. The third zone
is the unoccupied zones. Scientists believe that the likelihood of finding the species in these
areas is so low that they do not recommend scientific recovery permits, unless a ​Bombus affinis
may have accidentally been collected. According to USFWS’ Rusty Patched Bumble Bee 20
Interactive Map, Mecklenburg and Gaston Counties are located within an unoccupied zone.
Therefore, CWS concludes that this project will have no effect on the Rusty-patched
bumble bee.

Bald eagle (​Haliaeetus leucocephalus​)
The Bald and Golden Eagle Protection Act, enacted in 1940, prohibits anyone, without a 21
permit issued, from "taking" bald eagles, including their parts, nests, or eggs. Habitat for the
bald eagle includes cliffs and forested areas near estuaries, large lakes, reservoirs, rivers,
seacoast, and as they become more abundant, stands of undisturbed forest. The nearby
Catawba River is large enough to be considered a potential feeding source and is located within
one mile of the project area. The project limits also include patches of undisturbed deciduous
forest with large trees in the canopy (Figure 3). The previous EA document noted the location 22
of an off-site nest. However, no bald eagles or bald eagle nests were observed there or on-site
during the site visits on November 7 and November 19, 2019. Additionally, a review of the
NCNHP database on November 19, 2019, revealed no known occurrences of this species within
1.0 mile of the project study area. Due to the presence of suitable habitat, ​CWS concludes
that this project may affect, but is not likely to adversely affect the bald eagle. However,
if an eagle nest is observed within the property at any time during the project related
activities, consultation with the USFWS will be required.

Northern long-eared bat (​Myotis septentrionalis​)
The northern long-eared bat (NLEB) is one of the species of bats most impacted by the
white-nose syndrome disease. Summer habitat (roosting habitat) of the NLEB includes forests
and woodlots containing live trees and/or dead snags greater than three inches diameter at
breast height with cavities or crevices. Winter habitat (hibernacula) of the NLEB includes caves,
mines, rocky areas, or structures that mimic similar conditions such as culverts greater than
48-inch in diameter. The NLEB was listed as Threatened (T) on April 2, 2015. 23

The forested areas within the study area are potential habitats for the NLEB. A Standard Local
Operating Procedure for Endangered Species Act Compliance (SLOPES) was established for
NLEB between the USFWS Asheville and Raleigh Ecological Offices and the United States
Army Corps of Engineers (USACE), Wilmington District, on January 31, 2017. This SLOPES 24
defines how the USACE will make determinations of effect to the NLEB on projects in which the
USACE is the lead federal agency. Alternative Local Procedure 2 (ALP 2) applies for the Mt
Holly Pumping Station and Force Main site as the action area is within range of the NLEB, the 25
action area is located outside of a red 12-digit HUC as defined by the Asheville Ecological
Services Field Office, and consultation by the USACE is not required on other listed species or 26
critical habitat.

Determinations
Based on the literature search and the results of the on-site assessment for suitable habitat of
federally-protected endangered, threatened, and candidate species, suitable habitat was not
observed within the project limits for dwarf-flowered heartleaf, Carolina heelsplitter, Michaux’s
sumac, or smooth purple coneflower. Therefore, this project will have no effect on these

species. Suitable habitat was observed for Schweinitz's Sunflower but no individuals were
observed within the study area. Consequently, CWS concludes that this project will not affect
Schweinitz's Sunflower. No bald eagles or bald eagle nests were observed during the site visit,
but due to the presence of suitable habitat, CWS concludes that this project may affect, but is
not likely to adversely affect the bald eagle. If an eagle nest is observed within the property at
any time during the project related activities, consultation with the USFWS will be required. The
project area is not located within the currently occupied range of the rusty-patched bumble bee.
Additionally, based on the project area location, no tree removal activities will occur within a
150-foot radius of a known, occupied NLEB maternity roost from June 1-July 31, and no trees
will be removed within 0.25 miles of a known hibernaculum at any time of year. Therefore, any
incidental take on NLEB that may result from associated activities is exempt under the 4(d) rule
and notifications will follow the SLOPES agreement . Biological determinations requirements 27

A biological assessment was not conducted for this project. All biological determinations of
effect represent the best professional opinion of CWS and are not official determinations of
effect. It is the responsibility of the lead federal agency to render an official determination of
effect. Should the lead federal agency agree with CWS’s initial findings of no effect, then no
USFWS consultation is required to comply with Section 7 of the Endangered Species Act.
Should the lead federal agency’s determination of effect differ from the findings of CWS, formal
or informal consultation with USFWS may be required.

RE: Mt Holly Pump station; 2019-0368
Dear Julia McGuire:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached ‘Documented Occurrences’ tables and map.
The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that
have been documented within a one-mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile
radius of the project area, if any, are also included in this report.
If a Federally-listed species is documented within the project area or indicated within a one-mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water
Management Trust Fund easement, or an occurrence of a Federally-listed species is documented

RE: Threatened and Endangered Species Survey
Stowe Regional Water Resource Recovery Facility
Mecklenburg County, North Carolina

Dear Mr. Hamstead,

This letter presents the findings of a threatened and endangered species assessment conducted by
HDR for Charlotte Water to support planning efforts the Stowe Regional Water Resource Recovery
Facility (WRRF). The survey was conducted over a 253 acre Study Area located in Mecklenburg
County, North Carolina near the Catawba River (Figure 1).
The Study Area (Site) is located between the Catawba River and Belmeade Drive, south of NC 27
and north of US National Whitewater Center in Mt Holly, North Carolina and encompasses
approximately 253 acres. The Site consists of undeveloped forested areas, jurisdictional streams
and wetlands, and existing infrastructure associated with Long Creek Pump Station (Figure 2). The
proposed Stowe Regional WRRF is needed for a regional waste water treatment operation to
support continued growth in the region; therefore, the project proposes upgrades to the existing
Long Creek Pump Station, the construction of the proposed Stowe WRRF, access roads, and
sanitary sewer forcemains that will be installed by horizontal directional drilling methods (Figure 3).
HDR’s approach to this study involved conducting a desktop review of publically available data as
well as an on-site investigation to evaluate potential habitat for federally protected species. The
following sections provide a summary of HDR’s methods and findings of the desktop review and on-
site field reconnaissance. Attached to this letter are supporting figures and agency reports.
Desktop Review
HDR conducted a desktop review of protected species likely to occur on or in the vicinity of the
Project Site. Species addressed include those listed under the Endangered Species Act or critical
habitat designated under the Endangered Species Act.
HDR consulted the USFWS Information for Planning and Consultation (IPaC) database, which
summarizes species and trust resources under the USFWS’s jurisdiction that are known or
expected to be on or near the project area (IPaC Resource List, attached). The North Carolina
Natural Heritage Program (NCNHP) Data Explorer database was also queried for a list of federally

protected species with potential to occur within and in proximity to the project site, attached. Table 1
summarizes species that are federally listed on both lists. Species that are federally protected under
the Bald and Golden Eagle Protection Act (BGEPA) were also included in this review.

Field Reconnaissance Results
During the week of September 9 through the 13th, 2019, HDR environmental scientists conducted a
pedestrian survey of the site to verify the presence or absence of potential habitat for federally
threatened and endangered species listed in Table 1 that may occur on the site. A reference site of
Schweinitz’s sunflower was visited on September 9th and confirmed to be in flower. No habitat has
been identified for any of the species in Table 1 with the exception of summer roosting habitat for
the northern long-eared bat (NLEB).

Vertebrates
Bald eagle (Haliaeetus leucocephalus) [Federally Protected under BGEPA]
USFWS Recommended Survey Window: October 1 – May 15
Habitat Description: Bald eagles occur throughout much of the continental U.S. and Canada. The
species frequently builds their nests in live pines or cypress trees near large bodies of open water
and may congregate around fish processing plants, dumps, and below dams where fish
congregate. Nests typically measure 6 to 8 feet deep and 6 feet in diameter, and are cone shaped.
Bald eagles are opportunistic feeders and consume a variety of prey, which may be self-caught,
scavenged, or robbed from other bird species. The threat to this species is attributed to disturbance
and destruction of foraging and nesting habitat by urban and residential development (USFWS
1978).
No individuals of bald eagles were observed; therefore, no impacts to this species are anticipated.
Northern long-eared bat (Myotis septentrionalis) [Federally Threatened]
USFWS Recommended Survey Window: May 15 – August 15 (summer); January 15 – February 15
(winter)
Habitat Description: The northern long-eared bat is found across much of the eastern and north-
central U.S. and all Canadian provinces from the Atlantic coast to the southern Northwest
Territories and eastern British Columbia. The species’ range includes 37 states. White-nose
syndrome, a fungal disease known to affect bats, is currently the predominant threat to this species.
Northern long-eared bats have two distinct seasonal habitats. Winter habitats include caves and
mines, whereas summer habitats consist of roosting singly or in colonies underneath bark, in
cavities, or crevices of both live and dead trees. On rare occurrences this bat has also been found
roosting in man-made structures such as barns or sheds. Northern long-eared bats emerge at dusk
to fly through the understory of forested hillsides and ridges feeding on moths, flies, leafhoppers,
caddisflies, and beetles, which they catch while in flight using echolocation. The bat also feeds by
gleaning motionless insects from vegetation and water surfaces (USFWS 2015).
Mature trees (greater than 12 inches in diameter) that exhibit exfoliating bark (i.e., hickories and
oaks) and dead tree snags were observed within the forested portions of the Site and may serve as

potential roosting habitat; however, the site was reviewed in accordance with the NLEB Standard
Local Operating Procedures for Endangered Species (SLOPES) between the USACE, Wilmington
District, and the Asheville and Raleigh U.S. Fish and Wildlife Service (Service) Offices, and it was
determined that the project is located outside of the highlighted areas/red 12-digit HUCs and
activities in the project limits do not require prohibited incidental take; as such, this project meets
the criteria for the 4(d) rule and any associated take is exempted/excepted. As established in the
NLEB SLOPES, this project does not require prohibited intentional take of the NLEB and it meets
the criteria for the 4(d) rule.
Additionally, according to the NCNHP Data Explorer report, no known occurrences including
hibernacula and/or maternity roost trees have been documented within or within close proximity to
the Site.
Invertebrates
Carolina heelsplitter (Lasmigona decorata) [Federally Endangered]
USFWS Recommended Survey Window: Year-round; March 1 – September (optimal)
Habitat Description: The Carolina heelsplitter requires cool, clean, well-oxygenated water. It prefers
stable, silt-free stream bottoms and generally occurs where the stream banks are well-vegetated
with trees and shrubs. Historically, the Carolina heelsplitter was found in several locations in North
and South Carolina. Known populations for the Carolina heelsplitter in Mecklenburg County occur
only in the Goose Creek and Duck Creek watersheds within the Yadkin Pee-Dee River Basin and
the Sixmile Creek watershed within the Catawba River Basin (USFWS 2011).
The proposed project is located in the Long Creek watershed within the Catawba River Basin;
however, there are no known populations of the Carolina heelsplitter within the Long Creek
watershed. Moreover, the on-site streams are moderately degraded and exhibit erosion, incision,
and high sediment levels which are limiting habitat factors for this species. No mussels of any
species were observed and no suitable habitat for Carolina heelsplitter is present within the Site. No
impacts to this species are anticipated.
Vascular Plants
Michaux’s sumac (Rhus michauxii) [Federally Endangered]
USFWS Optimal Survey Window: May – October
Habitat Description: Michaux’s sumac is endemic to the inner Coastal Plain and lower Piedmont
regions, and grows in sandy or rocky, open, upland woods on acidic or circumneutral, well-drained
sands or sandy loam soils with low cation exchange capacities. The species is also found on sandy
or submesic loamy swales and depressions in the Sandhills region as well as in openings along the
rim of Carolina bays; maintained railroad, roadside, power line, and utility rights-of-way; areas

where forest canopies have been opened up by blow downs and/or storm damage; small wildlife
food plots; abandoned building sites; under sparse to moderately dense pine or pine/hardwood
canopies; and in and along edges of other artificially maintained clearings undergoing natural
succession. In the central Piedmont, it occurs on clayey soils derived from mafic rocks. The plant is
shade intolerant and, therefore, grows best where disturbance (e.g., mowing, clearing, grazing, and
periodic fire) maintains its open habitat (USFWS 1989).
The Site contains clayey soils that are not derived from mafic rock and are not well-drained. Due to
lack of suitable soils, no habitat exists for the Michaux’s sumac within the Site; therefore, no
impacts to this species are anticipated.
Schweinitz’s sunflower (Helianthus schweinitzii) [Federally Endangered]
USFWS Optimal Survey Window: late August – October
Habitat Description: Schweinitz's sunflower is endemic to the Piedmont of North and South
Carolina. The few sites where this rhizomatous perennial herb occurs in relatively natural vegetation
are in xeric hardpan forests. The species is also found along roadside rights-of-way, maintained
power lines and other utility rights-of-way, edges of thickets and old pastures, clearings and edges
of upland oak-pine-hickory woods, Piedmont longleaf pine forests, and other sunny or semi-sunny
habitats where disturbances (e.g., mowing, clearing, grazing, blow downs, storms, frequent fire)
help create open or partially open areas for sunlight. The species is intolerant of full shade and
excessive competition from other vegetation. Schweinitz’s sunflower occurs in a variety of soil
series, including Badin, Cecil, Cid, Enon, Gaston, Georgeville, Iredell, Mecklenburg, Misenheimer,
Secrest, Tatum, Uwharrie, and Zion, among others. It generally grows in shallow sandy soils with
high gravel content, shallow, poor, clayey hardpans, or shallow rocky soils, especially those derived
from mafic rocks (USFWS 1991).
The Site includes dense forested areas of varying ages, unmaintained areas heavily invaded by
invasive plant species, and regularly maintained mowed areas. Given the lack of disturbance to
reduce competition and presence of invasive species, it was determined that there was no suitable
habitat for Schweinitz’s sunflower present. Although it was determined that no suitable habitat was
present, surveys for Schweinitz’s sunflower were still conducted during the survey window and no
individuals were observed. Therefore, no impacts to this species are anticipated.
Smooth coneflower (Echinacea laevigata) [Federally Endangered]
USFWS Optimal Survey Window: Late May – October
Habitat Description: Smooth coneflower, a perennial herb, is typically found in meadows, open
woodlands, the ecotonal regions between meadows and woodlands, cedar barrens, dry limestone
bluffs, clear cuts, and roadside and utility rights-of-way. In North Carolina, the species normally
grows in magnesium- and calcium- rich soils associated with gabbro and diabase parent material,
and typically occurs in Iredell, Misenheimer, and P icture soil series. It grows best where there is

Threatened and Endangered Species Survey

abundant sunlight, little competition in the herbaceous layer, and periodic disturbances (e.g.,
regular fire regime, well-timed mowing, clearing) that prevent encroachment of shade-producing
woody shrubs and trees. In locations where woody succession is held in check, it is characterized
by a number of species with prairie affinities (USFWS 1995).
The Site includes dense forested areas of varying ages, unmaintained areas heavily invaded by
invasive plant species, and regularly maintained mowed areas. These areas within the Site were
not determined to be suitable habitat for smooth coneflower; therefore, no impacts to this species
are anticipated.

Effect Determination
Based on the desktop review of the USFWS County List, IPaC, the NCNHP Data Explorer Report,
and the subsequent field survey for the presence or absence of potential habitat, the project will
have no effect on the bald eagle, Carolina heelsplitter, Michaux’s sumac, Schweinitz’s sunflower, or
smooth coneflower. The project may affect, but is not likely to adversely affect the northern long-
eared bat, but meets the criteria for the 4(d) rule and any associated take is exempted/excepted.
We ask that you review the project area based on the attached information to determine if there will
be any adverse impacts to federally protected species. If you have any questions or require
additional information, please contact me at 704-338-6710 or [e-mail].
Sincerely,

HDR Inc.

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-

Endangered species
This resource list is for informational purposes only and does not constitute an analysis of project
level impacts.
The primary information used to generate this list is the known or expected range of each species.
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
.
1. Species listed under the Endangered Species Act are threatened or endangered; IPaC also shows
species that are candidates, or proposed, for listing. See the listing status page for more

Probability of Presence Summary
The graphs below provide our best understanding of when birds of concern are most likely to be
present in your project area. This information can be used to tailor and schedule your project activities
to avoid or minimize impacts to birds. Please make sure you read and understand the FAQ “Proper
Interpretation and Use of Your Migratory Bird Report” before using or attempting to interpret this

Probability of Presence ( )
Each green bar represents the bird's relative probability of presence in the 10km grid cell(s) 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
Survey Timeframe
Surveys from only the last 10 years are used in order to ensure delivery of currently relevant
information. The exception to this is areas off the Atlantic coast, where bird returns are based on all
years of available data, since data in these areas is currently much more sparse.

Tell me more about conservation measures I can implement to avoid or minimize impacts to migratory birds.
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 and/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 migratory birds potentially occurring 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 10km 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), or a species that has a particular vulnerability to offshore activities or
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. "Non-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?

Wetlands in the National Wetlands Inventory
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.
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.

10/3/2019https://ecos.fws.gov/ipac/location/QOYIDXXKLBEANNDCO4VSMVY2PI/resources
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 proprietary jurisdiction of any Federal, state, or local government or to establish the
geographical scope of the regulatory programs of government agencies. Persons intending to engage in activities

RE: Stowe Project
Dear Jessica Tisdale:
The North Carolina Natural Heritage Program (NCNHP) appreciates the opportunity to provide
information about natural heritage resources for the project referenced above.
A query of the NCNHP database indicates that there are records for rare species, important natural
communities, natural areas, and/or conservation/managed areas within the proposed project
boundary. These results are presented in the attached ‘Documented Occurrences’ tables and map.
The attached ‘Potential Occurrences’ table summarizes rare species and natural communities that
have been documented within a one-mile radius of the property boundary. The proximity of these
records suggests that these natural heritage elements may potentially be present in the project area
if suitable habitat exists. Tables of natural areas and conservation/managed areas within a one-mile
radius of the project area, if any, are also included in this report.
If a Federally-listed species is documented within the project area or indicated within a one-mile
radius of the project area, the NCNHP recommends contacting the US Fish and Wildlife Service
(USFWS) for guidance. Contact information for USFWS offices in North Carolina is found here:
https://www.fws.gov/offices/Directory/ListOffices.cfm?statecode=37.
Please note that natural heritage element data are maintained for the purposes of conservation
planning, project review, and scientific research, and are not intended for use as the primary criteria
for regulatory decisions. Information provided by the NCNHP database may not be published
without prior written notification to the NCNHP, and the NCNHP must be credited as an information
source in these publications. Maps of NCNHP data may not be redistributed without permission.
Also please note that the NC Natural Heritage Program may follow this letter with additional
correspondence if a Dedicated Nature Preserve, Registered Heritage Area, Clean Water
Management Trust Fund easement, or an occurrence of a Federally-listed species is documented
near the project area.
If you have questions regarding the information provided in this letter or need additional assistance,
please contact Rodney A. Butler at [e-mail] or 919-707-8603.
Sincerely,
