Morgan Creek Sewer Interceptor Replacement Bat Surveys
This report contains the results of the federally proposed as Endangered tricolored bat (Perimyotis
subflavus; PESU) summer presence/absence survey performed by Ecosystem Planning and
Restoration (EPR) for the Morgan Creek Sewer Interceptor Replacement Project in Chapel Hill,
Orange County, NC (Appendix A, Figure 1).
PROJECT DESCRIPTION
The Project Area includes 23 acres situated almost entirely within property owned by the State of
North Carolina and encompasses all phases of the project (see below). The Project Area consists
of 20.7 acres of forest, and 2.3 acres along the sewer easements, which are regularly maintained
in an herbaceous condition. Morgan Creek meanders through the length of the Project Area, which
is dominated by mature deciduous forest. No wetlands or ponds are present in the Project Area.
The sewer easements are dominated by herbaceous exotic invasive species, mainly Japanese
stiltgrass (Microstegium vimineum); however, the canopy is closed or nearly closed over the
easements in most areas due to the adjoining forest vegetation. Mature trees and shrubs occur
along stream banks. Dominant species in the forested portion of the Project Area include American
beech (Faugs grandifolia), river birch (Betula nigra), tulip poplar (Liriodendron tulipifera),
American sycamore (Platanus occidentalis), mockernt hickory (Carya tomentosa), red maple
(Acer rubrum), American pawpaw (Asimina triloba), and musclewood (Carpinus caroliniana).
Phase I of the project involves the installation of approximately 2,100 linear feet of 36-inch gravity
sanitary sewer as a parallel replacement for the existing gravity sewer. The new sewer will be
installed via open cut and will involve both permanent and temporary impacts to the Project
Area. Permanent impacts include an approximately 30-ft wide corridor centered along the new
sewer (approximately 2,100 feet long) to be used for permanent maintenance
access. Approximately half of this permanent 30-ft wide corridor is currently cleared and utilized
for maintenance of the existing sewer. Therefore, the new 30-foot-wide corridor's additional
"disturbance" beyond the existing cleared corridor is limited (Figure 1). Temporary impacts
include a variable width corridor which averages approximately 30-foot-wide for the length of the
project (approximately 2,200 feet long) that will be restored. The purpose of the temporary
impacts is to accommodate construction of the project site to stage materials and equipment.
Phase II of the project involves the installation of approximately 1,500 linear feet of 36-inch
gravity sanitary sewer as a parallel replacement for the existing gravity sewer. The new sewer is
anticipated to be installed via open cut and will result in permanent and temporary impacts. Design
of Phase II has not begun, however permanent impacts are assumed to be an additional 15-ft of
cleared area (parallel to existing cleared easement). Additionally, permanent impacts may include
installation of permanent access from Flat Stone Court or the Mason Farm Wastewater Treatment
Plant. Temporary impacts are assumed to be a 30-foot cleared area parallel to the alignment to be
used during construction. It is likely that two approximately 50 feet by 50 feet laydown areas will
be placed within the project area but the location of these is not yet known.
Clearing for Phase I will total 3.68 acres, and between 3 and 7 acres will be cleared for Phase 11.
Areas outside the Limits of Disturbance but within the overall Project Area will be preserved. A
30-foot-wide corridor along the new pipe will be reseeded with natural seed approved by the NC
Botanical Gardens (NCBG). Areas outside of that 30-ft wide area will be restored via woody
plants approved by the NCBG.

Morgan Creek Sewer Interceptor Replacement Bat Surveys
METHODS
The summer presence/absence survey was conducted in accordance with the U.S. Fish and
Wildlife Service's (USFWS) 2023 Range -wide Indiana Bat and Northern Long-eared Bat Survey
Guidelines (Guidelines). This survey utilized a two -phased approach: Phase 1) desktop and field -
based habitat assessments, and Phase 2) acoustic surveys. Zero -crossing acoustic detectors were
deployed during field assessments and resulting data were processed using Bat Call Identification
(BCID) Version 2.8b software. Qualified EPR personnel carried out all phases of the survey and
specific roles are summarized in Table 1; resumes for relevant staff are provided in Appendix B.
Heather Wallace (Native Endangered & Threatened Species Recovery Permit ES8143013-1) led
the survey and analysis efforts.

HABITAT ASSESSMENT
Desktop Analysis
Prior to conducting field work, a desktop land cover analysis was performed to identify suitable
PESU habitat within the Project Area. Specifically, aerial photography and Google Earth imagery
were reviewed to determine areas that may be used by PESU for foraging and roosting during the
breeding season. Determinations were based on forest patch size, proximity to closed -canopy
forests, and landscape features that may be used by bats commuting between roosting and foraging
habitats (e.g., forested tracts, wetlands, streams). Edges of larger forest openings, edges of riparian
areas, and open water were noted as these features seem to be preferred by PESU. Dense, unbroken
forests, narrow road cuts, and areas highly fragmented by residential or commercial developments
were generally not considered suitable PESU habitat. All the Project Area (23 acres) was
determined to be possible suitable habitat as it consists of forest habitat interspersed with clearings
and associated edge habitat that could be utilized as roosting, foraging or commuting areas by
PESU.
EPR also reviewed the land cover imagery for the presence of any areas that could potentially
support natural hibernacula, including karst or similar geological formations. No natural
hibernacula or abandoned mines were identified in the Project Area.
Maps and GPS coordinates were produced for use in the field that demarcated suitable habitat
within the Project Area, as well as the number and proposed locations of acoustic detectors
required to survey the area.

Morgan Creek Sewer Interceptor Replacement Bat Surveys
Field Assessment
On August 7, 2023, EPR conducted a site visit to verify the presence of and describe the PESU
habitat identified during the desktop analysis. Preliminary detector locations were also identified
during this site visit. Detectors were deployed on August 9, 2023, at seven locations (or stations)
for the nights of August 9, and 10, 2023 (Appendix A, Figure 1). On August 9, EPR biologists
decided to install detector MCI in a location further west to avoid potential interference from
overhead powerlines at the original location. All other detector locations identified in the Study
Plan provided to the USFWS on August 8, 2023, remained the same. The detector at MC7
malfunctioned overnight on August 9 and 10, 2023 and was replaced with another detector on the
nights of August 11 and 12, 2023. It successfully recorded bat calls during those nights. General
habitat descriptions at each station are provided below in Table 2. The Phase 1 Summer Habitat
Assessment, Phase 2 Study Plan, and USFWS authorization letter are included in Appendix C.

ACOUSTIC PRESENCE/ABSENCE SURVEYS
Detector Type
Anabat Express ultrasonic bat detector/recorders (Titley Scientific) equipped with omnidirectional
ultrasonic US-0 V3 microphones were used for the duration of the survey effort. Detectors were
set to record from an hour before sunset to an hour after sunrise and files were saved in .zca format
on internal SD cards. The detectors and accessories are fully waterproof and were powered by
internal four AA NiMH batteries. At the time of deployment, each detector was tested by rubbing
fingers in front of the microphone and watching for the Microphone LED to flicker to confirm that
an ultrasonic audio signal was detected. In addition, each detector setup was tested for proper
functioning by waving a magnet in front of the case and watching for the Check LED to flash. Log
files were reviewed when units were pulled to verify proper functioning for the duration of the
survey.
Detector Deployment
Seven detectors were positioned in suitable habitat within the Project Area to ensure that potential
habitats were sampled in accordance with the Guidelines. Seven detectors were deployed in the
following habitat types:
• Sewer easements with varying canopy closure situated within closed canopy forests.
• Riparian areas near pools or riffles.
Omnidirectional microphones were mounted at the top of poles approximately 3.66 meters (12
feet) above the ground surface to avoid herbaceous vegetation and to elevate the microphones' cone of
H

detection. Tripods were used to stabilize the poles and to mount the detectors in a locked metal box. Detectors
were placed in the center of flight paths to the extent possible without blocking pedestrian access to the trail
system that followed some easements. Microphones were oriented horizontally and in line with
suspected flight paths to increase the number of call pulses and quality of recordings. Therefore,
specific orientation was determined by microsite conditions. Appendix D contains acoustic
detector data sheets, including station conditions and photographs showing detector placement,
surrounding habitat, and airspace around each microphone, and Figure 1 (appendix A) shows the
detector locations and orientation of each microphone.
Following is a summary of the acoustic presence/absence survey effort
• The total Project Area was approximately 23.0 acres.
• The area of Project with suitable PESU habitat was approximately 23.0 acres.
• Six detectors were deployed on the nights of August 9 and 10, 2023, and one detector was
deployed on the nights of August 11 and 12, 2023, for a total of 14 detector nights.
ANALYSIS
EPR analyzed the recorded data according to the Guidelines, per Phase 2, Step 6 (Automated
Acoustic Analysis)..zca files generated each night by each detector were converted to .zc files
using the Analysis tool within the Anabat Insight software program. The call files were then
analyzed using Bat Call Identification software (BCID East, Version 2.8b) using the classifier for
species of bats in North Carolina and default filters. Myotis sodalis, Myotis leibii, and Myotis
grisescens were unchecked as potential species because the known distribution of these species
does not extend east to the NC Piedmont. Results were summarized by detector site and by night.
RESULTS
All weather requirements (including temperature, precipitation, and average wind speed) were met
during all nights of the survey (Table 3). Historic weather data was obtained for the nearby NOAA
weather station at Raleigh -Durham International Airport via Weather Underground
(www.weatherunderground.com).

On the nights of August 9-12, 2023, a total of 6,986 bat passes were recorded at the seven stations
(Table 4). Calls representing ten bat species were identified by BCID. A total of 623 passes were
classified as PESU by BCID, and bat passes classified as PESU were identified at every detector
location. Maximum Likelihood Estimates (MLEs) signify ap-value less than 0.05 for this species
at all detector locations each night as well, indicating that PESU is likely present within the Project
Area (Table 5).

Note 2: Maximum Likelihood Estimates (MLEs) interpretation — values <0.05 indicates there is 95% confidence that
the species is present. Bold values indicate significance, and high confidence level in species presence.
CONCLUSION
The Project Area provides suitable roosting and foraging habitat for PESU. Based on automated
acoustic analysis for each night at each site PESU presence is considered likely at all seven
sampling sites, with PESU accounting for 8.9% of the total bat passes. Therefore, it can be
assumed that PESU are present within the Project Area.
Per Ms. Wallace's USFWS permit conditions, the results of this survey will be reported to USFWS
and the North Carolina Wildlife Resources Commission. Additional coordination with USFWS is
recommended as part of the environmental review process for this Project.

■ Northern Long-eared Bat Surveys for Eastern
Region, NCDOT, Various Counties, Eastern NC.
Heather served as the Lead Biologists for this
NCDOT-awarded on -call contract, producing five
task orders over a four-year period (2016-2019) to
perform surveys for the federally threatened
northern long-eared bats (Myotis septentrionalis)
throughout various locations in the coastal plain of
North Carolina. Little was known about this disjunct
population of bats, including their population range,
reproductive season, and roost preferences. Using
acoustic detectors, winter, spring, and summer
mist -netting, and radiotelemetry tracking, Biologists
identified locations where the species was not
previously known to occur, captured and tracked

reproductive males and females, located maternity and non -maternity roost trees,
performed emergence surveys, and conducted habitat analysis of mist -net sites and roost
locations. More than 800 bats of 9 species were captured during more than 180 nights of
mist -netting. Thirteen northern long-eared bats were tracked to more than 36 roost trees,
where emergence surveys were performed.
■ Bat Mist Netting and Acoustic Surveys, NCDOT, Statewide, NC. STATEWIDE, NC.
Heather was the Project Manager and Lead Biologist providing extensive Northern long-
eared bat mist -netting and acoustic surveys in Central and Eastern North Carolina.
Twenty-seven (27) nights of netting were completed at 21 sites and seven counties. The
survey efforts resulted in the capture of 166 bats representing eight species. As a part of
these surveys, the federally threatened Northern long-eared bat was captured in two new
counties where the species was previously undocumented. Acoustic surveys
approximated these efforts. A comprehensive survey report was also submitted as part
of this project.

Assessments, NCDOT, Various Counties, NC. Seven bridges in five counties were
evaluated for signs of bat use and overall quality as potential roost sites. Where
applicable, habitat assessments were conducted for Indiana bat (Myotis sodalis), gray bat
(Myotis grisescens) and northern long-eared bat (Myotis septentrionalis). In addition,
surrounding forested areas were evaluated for potential as summer roosting and foraging
locations. Heather evaluated the available habitat based on the NCDOT's Standard
Operating Procedures (SOP) for Preliminary Bat Habitat Assessments (Structures, Caves
and Mines), and the USFWS Northern Long-eared Bat Interim Conference and Planning
Guidance (2014).
■ Northern Long-eared Bat Training Seminars, NCDOT, Wake and Lee Counties, NC.
While employed with the NCDOT, Heather coordinated and instructed several one -day
seminars for consultants on the status of the proposed listing of the Northern long eared
bat, including natural history, population status, current research on white -nose
syndrome, and the review of NCDOT Standard Operating Procedures for bat habitat
assessment of bridges/culverts, caves/mines, and abandoned structures.
■ Programmatic Biological Assessment for Northern Long-eared Bat, NCDOT,
Eastern Counties, NC. Heather participated in an interagency team of representatives
from NCDOT's Biological Surveys Group, Federal Highway Administration (FHWA), US
Army Corps of Engineers (USACE), and USFWS to develop a strategy to address the
potential effects that NCDOT projects may have on the northern long-eared bat (Myotis
septentrionalis). The goal of the working group was to "Advance (transportation) projects
forward without schedule delays and ensure species protection/uplift in the most efficient
way". NCDOT received a favorable programmatic biological opinion from USFWS, which
provides incidental take coverage for northern long-eared bat and ensures compliance

with Section 7 of the Endangered Species Act for five years for all NCDOT projects with
a federal nexus in eastern NC. As a result of the interagency coordination, NCDOT
projects in this part of the state will not suffer scheduling delays due to a need for
Endangered Species Act compliance related to species. Furthermore, a five-year
research project was proposed as a conservation measure and is anticipated to provide
valuable data about the distribution and ecology of the species in this portion of its range.
■ 1-26 Widening Gray Bat Surveys and Consultation. Buncombe and Henderson
Counties, NC. Heather was the Lead Biologist for this project that involved completion of
acoustic surveys, structure checks, and a Biological Assessment for gray bat for the 24-
mile 1-26 widening. Close coordination with NCDOT, NCWRC, NPS, and USFWS was
necessary to ensure that data was collected and analyzed in the most appropriate
manner. Biologists checked a total of 24 bridges (or bridge pairs) and 18 culverts and
found evidence of bat use on one bridge. Three of the bridges were checked while utilizing
a hydra lift truck. Acoustic surveys were performed for a 13-week period and 322 acoustic
nights of data were collected, processed, and vetted from 13 locations. An additional 13
weeks of acoustic data were collected and processed at the 1-26 crossing of the French
Broad River, where gray bat activity was high, to determine the time of year that bat
activity decreases, which is indicative of the time of year bats begin their hibernation
period. Heather coordinated with NCDOT, FHWA, NPS, and USFWS as part of the
Endangered Species Act Section 7 consultation process to prepare a Biological
Assessment, including conservation measures that were acceptable to all stakeholders,
and secured a favorable Biological Opinion from USFWS.
■ 1-4400/1-4700 1-26 Widening Gray Bat Acoustic and Thermal Video Monitoring,
NCDOT, Buncombe County, NC. Heather served as Project Manager and Lead
Biologist to perform acoustic surveys, structure checks, and include a Biological
Assessment for gray bats for the 1-26 widening between Hendersonville and Asheville.
Close coordination with NCDOT, NCWRC, NPS, and USFWS was necessary to ensure
that data was collected and analyzed in the most appropriate manner for the project.
Biologists checked a total of 24 bridges (or bridge pairs) and 18 culverts, and found
evidence of bat use on one bridge. Three of the bridges were checked while utilizing a
hydra lift truck. Acoustic surveys were performed for a 13-week period during the summer
of 2017. During the survey period, 322 acoustic nights of data were collected, processed,
and vetted from 13 different locations throughout the study area. An additional 13 weeks
of acoustic data were collected and processed at the 1-26 crossing of the French Broad
River, where gray bat activity was high, to determine the time of year that bat activity
decreases, which is indicative of the time of year bats begin their hibernation period.
Heather coordinated with NCDOT, FHWA, NPS, and USFWS as part of the Endangered
Species Act Section 7 consultation process. The Biological Assessment for this project
was completed in 2018, and a favorable Biological Opinion was subsequently rendered
by USFWS. This unique project allowed the team to explore various methods for
recording bat activity using thermal and infrared imagery. In addition, the team refined the

use of ThruTracker software to automate review of the video and identification of bat
"tracks" to better understand how active construction may affect bat activity within the
construction zone. Heather was Project Manager.
■ Bat Acoustic Surveys and Consultation, Private Client, Jackson County, NC.
Heather served as project manger on a quick -turnaround assignment to perform habitat
assessments and acoustic surveys for a 5.3-acre parcel in Jackson County necessary to
facilitate the repair of a failing retaining wall adjacent to a highway. Biologists surveyed
for three (3) species threatened and endangered bat species listed by US Fish & Wildlife
Service (USFWS), which included Indiana bat (Myotis sodalis), northern long-eared bat
(Myotis septentrionalis), and gray bat (Myotis grisescens). Habitat assessments
consisted of determining if potentially suitable habitat for the bats species was present,
following up to date USFWS protocols. Acoustic monitoring recorded bat calls to
determine presence/probable absence of threatened and endangered bat species.
■ U-A-3403B, NC 191 Widening, USFS and USFWS Species Surveys and Biological
Evaluation, NCDOT, Buncombe County, NC. Heather led a group of biologist
surveying for USFWS federally listed, USFS Species of concern, and North Carolina state
listed species along a four -mile widening project of NC 191. Aquatic surveys of fish,
mussels, amphibians, benthic macroinvertebrates, and crustaceans included USFWS
listed blotchside logperch (Percina burtoni), longhead darter (Percina macrocephala),
hellbender (Cryptobranchus alleganiensis), Appalachian elktoe (Alasmidonta
raveneliana), and French Broad crayfish (Cambarus reburrus) in addition to 26 USFS and
North Carolina special concern or listed species along 5,600 linear meters of aquatic
habitat. In addition, biologists performed habitat assessments and noted potential habitat
for federally protected northern long-eared bat (Myotis septentrionalis), and Indiana bat
(Myotis sodalis). Additional botanical, arthropod, avian, herpetological, and terrestrial
gastropod surveys were conducted in 9.89 acres of forest service property potentially
affected by the widening project. Notable discoveries included new occurrences of
Federally endangered Appalachian elktoe (Alasmidonta raveneliana), North Carolina
threatened creeper mussel (Strophitus undulatus), and North Carolina endangered
slippershell mussel (Alasmidonta viridis) in the French Broad River. In addition, biologists
confirmed the continued presence of French Broad Crayfish (Cambarus reburrus) in Bent
Creek. A Biological Evaluation is in preparation for this project to summarize findings of
field investigations and predict potential effects on RTE species.
■ A-0010A, US 19/23 (Future 1-26) Improvements, Gray Bat Consultation, NCDOT,
Buncombe, County, NC. NCDOT proposed improvements to a 12-mile portion of US
19/23 from north of 1-240 in Asheville to just south of Exit 13 (Forks of Ivy —Stockton Road)
near Mars Hill in Buncombe County, NC. Heather served as Lead Biologist, collecting
three years of acoustic data to better understand the activity levels of the federally
endangered gray bat which is known to occur in the area. Roughly 400 detector nights of
data, collected at six detector locations was processed through BCID and analyzed to

and culverts for roosting bats were also performed. This information will be used to
develop a Biological Assessment, including conservation measures that will reduce
potential effects on gray bats that forage and commute within the project study area.
■ 1-4400/1-4700, 1-26 Widening Gray Bat Surveys and Consultation, NCDOT,
Buncombe and Henderson Counties, NC. Heather served as Project Manager and
Lead Biologist to complete acoustic surveys, structure checks, and a Biological
Assessment for gray bats for the 25.5-mile widening of 1-26 between Hendersonville and
Asheville. Close coordination with NCDOT, NCWRC, NPS, and USFWS was necessary

Morgan Creek Interceptor Project
Brief Project Description/Summary
The project installs approximately 2,100 linear feet of 36-inch gravity sanitary sewer as a parallel
replacement for the existing gravity sewer. The new sewer will be installed via open cut and will involve
both permanent and temporary impacts to the project area. Permanent impacts include an
approximately 30-ft wide corridor centered along the new sewer (approximately 2,100-feet long) to be
used for permanent access for maintenance of the sewer. Approximately half of this permanent 30-ft
wide corridor is currently cleared and utilized for maintenance of the existing sewer. Therefore, the new
30-ft wide corridor's additional "disturbance" beyond the existing cleared corridor is limited. Temporary
impacts include a variable width corridor which averages approximately 30-ft wide for the length of the
project (approximately 2,200 feet long) that will be restored. The purpose of the temporary impacts is to
accommodate construction of the project site for stage and materials and equipment.
Phase II: The project installs approximately 1,500 linear feet of 36-inch gravity sanitary sewer as a
parallel replacement for the existing gravity sewer. The new sewer is anticipated to be installed via open
cut and result in permanent and temporary impacts. Design of Phase II has not begun, however
permanent impacts are assumed to an additional 15-ft of cleared area (parallel to existing cleared
easement). Additionally, permanent impacts may include installation of permanent access from Flat
Stone Court or the Mason Farm WWTP. Temporary impacts are assumed to be a 30-ft cleared area
parallel to the alignment to be used during construction. It is likely two approximately 50-ftx50-ft
laydown areas will be placed within the project area but the location of these are not yet known.
