S&ME Project No. 7335-20-083
Dear Ms. Stygar and Mr. Wojoski:
On behalf of Dominion Energy North Carolina (DENC), S&ME, Inc. (S&ME) is submitting this notification to
inform you of pre-authorized repair work they plan to conduct in order to replace an exposed segment of
their M-217 natural gas transmission pipeline, along with proposed work to provide equipment access to
an isolated segment of their existing easement.
The project consists of two phases. Phase 1 consists of emergency repairs to an exposed natural gas
transmission pipeline. Authorization to proceed with performance of these repairs under Nationwide
Permit No. 3 (Maintenance) and General Certification (GC) 4132 without submission of a pre-construction
Notification (PCN) was confirmed by the US Army Corps of Engineers (USACE) and the N.C. Division of
Water Resources (NCDWR). For your records, we have included drawings and descriptions of the Phase 1
repair work in this submittal.
Phase 2 of the project consists of construction of a “low-water” equipment crossing of a headwater
wetland and intermittent stream channel located north of the exposure. This work is not considered an
emergency, and as such, was not authorized in conjunction with Phase 1. We anticipate that construction
of the low water crossing can be authorized under NWP-12 (Utility Line Activities) and GC 4133, but does
require pre-construction notification because the subject waterbody is classified as a High-Quality Water
(HQW).

General Project Information
The purpose of Phase 1 is to replace an exposed segment of gas line. The purpose of Phase 2 is to
construct a permanent crossing of a wetland and intermittent stream north of the exposure such that
mowing equipment can access the area with minimal disturbance and avoid getting stuck.
The project area consists of a portion of DENC's 50-foot wide M-217 natural gas pipeline easement. The
existing easement is abutted on either side by woodlands and is located on the west side of Wright Road
in Kannapolis, Rowan County, North Carolina. A portion of the existing gas line has become exposed in an
unnamed tributary to East Fork Coddle Creek. The maintained easement is abutted by forested areas on
either side. Small stream/wetland complexes are located north and south of the stream where the
exposed was identified. Mowing equipment crosses these areas at locations where riprap has historically
been placed. Riprap at the northern crossing has become dispersed or embedded to a degree that it is no
longer effective to provide equipment support. The vicinity consists of open land, pastures, forested areas
and scattered residential development.
The general location of the review area is depicted on the attached Site Vicinity Exhibit (Figure 1). The
review area is also depicted on the appropriate portion of the Enochville, NC USGS Topographic Map
Exhibit (Figure 2), Rowan County Soils Exhibit (Figure 3), and an Approximate Waters of the US Exhibit
(Figure 4).
The review area is located in the Yadkin-Pee Dee Basin (HUC 030401050104). Review of the US Geological
Survey (USGS) Topographic Map (Figure 2) depicts the review area as forested land flanked by open areas
to the north and south. Stream 2 is depicted as a dashed blue line that flows to the southwest from an
off-site pond. Soils mapped within the review area (Figure 3) are limited to Pacolet sandy loam (Typic
Kanhapludults). Pacolet soils are not classified as hydric.
Photographs of conditions at the site encountered during the site visit are included in the information
submitted with the online PCN.
Jurisdictional Areas
The subject streams located within the review area were delineated by S&ME on July 14, 2020. The subject
stream channels are unnamed tributaries to East Fork Coddle Creek (DWR Index No. 13-17-6-1, Class WS-

II; HQW). Streams 1 and 3 are classified as intermittent, while Stream 2 exhibits perennial flow. The
pipeline exposure is located within Stream 2. Within the easement, the width of Stream 2 ranges from
approximately 10-15 feet in width, with eroded, nearly vertical banks that are approximately six feet deep.
S&ME also assessed the remaining review area for the presence of wetlands or additional water bodies.
The delineation was conducted utilizing currently accepted methods for wetland determination, as set
forth in the 1987 Corps of Engineers Wetlands Delineation Manual and the corresponding Eastern
Mountain and Piedmont Region USACE Regional Supplement Guide. Two wetlands areas (WA and WB)
were also identified in the review area. Both are classified as headwater wetlands. The approximate limits
of the jurisdictional features are depicted on Figure 4. A wetland and upland data form prepared for
Wetland B (which is representative of both the wetland areas observed) have been included with this
submittal.
Description of the Work
Phase 1: To replace the segment of exposed gas line, DENC plans to install a new section of pipe below
the existing streambed at a sufficient depth to help prevent its future exposure. The work will be
conducted using industry-standard mechanized equipment (track hoe and side-boom). Access for
construction equipment will be from Wright Road to the south. To prevent impacts to a stream/wetland
located between Wright Road and the exposure, timber mats will be placed across an existing riprap
crossing. The mats will then be removed and the area restored upon project completion.
The pipe replacement work will be conducted "in-the-dry" by constructing coffer dams upstream and
downstream of the exposure. A dry workspace will then be established by pumping clean water from
above the upstream coffer dam and around the work area to below the downstream coffer dam. The
water will be pumped into a filter bag or dewatering structure sited in a vegetated area on the west side
of the work area, and the water will eventually flow back into the stream. Secondary containment will be
utilized to prevent any leakage associated with the pump.
The new pipe will be staged on-site and fabricated as a “box-section” that can be efficiently installed by
conventional methods. The new pipe will be placed at a depth approximately five feet below the bed of
the stream in order to maintain sufficient separation from the ground surface. Upon installation and tie-in
of the new gas line segment, the exposed gas line segment will be removed. To inhibit the potential for
future bank erosion and instability, the streambanks within the easement, which are currently eroded and
nearly vertical, will then be graded at a 3:1 slope, seeded with a native riparian seed mix and matted with
coir fabric.
Temporary impacts to Wetland A will be required in order to place an equipment mat and establish
temporary construction access . Although a small equipment crossing was historically constructed in WA
to accommodate passage of tractors with bush hogs and maintenance equipment, it was considered
insufficient for the equipment necessary to repair the exposed pipe.
Phase 2: Vehicular passage of maintenance equipment through Wetland B cannot be accomplished
without significant disturbance to the wetland, and the risk of equipment getting stuck. To provide more
reliable equipment access to this area during future maintenance activities, a new low-water crossing will

be constructed at this location. The low water crossing will be established by installing an articulated
concrete block (ACB) mattress across the stream and wetland. The mattress will be embedded such that
the stream can continue to flow through the area. The embedded mattress will provide a firm equipment
base, allowing mowing equipment to cross the area with minimal disturbance, and the original grade and
contour of the wetland can be better maintained.
Temporarily affected wetland areas will be restored to the approximate pre-disturbance contours and
conditions, seeded with a customized riparian seed mix, and stabilized with coir matting. Construction
drawings showing the proposed crossing including plan, cross-section, and cofferdam detail drawings are
included with the information submitted online.

Protected Species
To assist you with determining compliance with applicable sections of the Endangered Species Act (ESA)
of 1973 (16 USC 1531-1543), S&ME submitted a request for information to the North Carolina Natural
Heritage Program (NCNHP). The NCNHP responded with an August 11, 2020 report that listed natural
areas and protected species with documented occurrences within one mile of the project area. The report
identified no occurrences of federally protected species within one mile of the site,
S&ME also consulted the FWS Information for Planning and Consulting (IPaC) system for a list of species
that are known or expected to be near the assessment area. The IPac report identified the following
species as having potential for direct or indirect affected by activities in the assessment area:

Descriptions of the relevant species taken from FWS sources are provided below.
Northern Long-eared Bat
Status: Federally-Listed Threatened
Biological Determination: May Affect (4(d) Rule Exception)
The northern long-eared bat (Myotis septentrionalis) is a medium-sized bat about three to 3.7 inches in
length but with a wingspan of 9 to 10 inches. This bat generally is associated with old-growth forests
composed of trees 100 years old or older. It relies on intact interior forest habitat, with low edge-to-
interior ratios. Relevant late-successional forest features include a high percentage of old trees, uneven
forest structure (resulting in multilayered vertical structure), single and multiple tree-fall gaps, standing
snags, and woody debris.
Foraging occurs within forests, along forest edges, over forest clearings, and occasionally over ponds.
Eleven individuals (10 males, 1 female) tagged with chemical lights observed during the summer in
Missouri, foraged almost exclusively among the trees of hillside and ridge forests, rather than utilizing
floodplain and riparian forests; frequently foraging occurred within one to three meters of the ground.
Foraging bats doubled back frequently and only slowly moved out of the observation area. In Iowa,
females were found primarily foraging in mature deciduous uplands with adjacent deep ravines and in a
disturbed riparian area with an adjacent floodplain and agricultural lands.
Hibernation occurs primarily in caves, mines, and tunnels, typically those with large passages and
entrances, relatively constant and cool temperatures, high humidity, and no air currents. Hibernators
frequently roost in crevices, drill holes, and similar sites where they may be overlooked during surveys, but
roosting in the open is not uncommon. A lack of suitable hibernacula may prevent occupancy of areas
that otherwise have adequate habitat.
The project as proposed should not have a significant effect on northern long-eared bat because the
replacement pipe will be installed within an existing utility corridor that is already cleared of woody
vegetation. Consultation through the FWS IPac System indicates that the project is consistent with
activities analyzed in the January 5, 2016, Programmatic Biological Opinion (PBO) on Final 4(d) Rule for
the Northern Long- eared Bat and Activities Excepted from Take Prohibitions. Accordingly, DENC’s
responsibilities under ESA Section 7(a)(2) with respect to the northern long-eared bat are satisfied.

Schweinitz’s Sunflower
Status: Federally-Listed Endangered
Biological Determination: No Effect.
Schweinitz’s sunflower is a perennial herb in the aster family that generally grows up to five feet in height.
This plant has tuberous roots, with each stem attached to a single tuberous root. The stems are scabrous
(rough) and generally reddish in color. The leaves are soft pubescent below and scabrous on the upper
surface. The ray flowers are yellow, while the disk flowers are purplish. Schweinitz’s sunflower generally
blooms during the month of September. The habitat of Schweinitz’s sunflower is open woods, roadsides,
and powerline easements, often on basic soils with bare spots or a gravel component. The preferred sites
are characterized by abundant sunlight and little competition in the herbaceous layer.
Schweinitz’s sunflower is listed as a current record for Rowan County. The review area contains potentially
suitable habitat for Schweinitz’s sunflower within the existing utility easement and roadside area that will
be used for access. However, no populations of this Helianthus species were observed during our site
visits, and due to the small size of the review area, the project should have no effect on this species.
Copies of the NCNHP and IPac reports are included with the information submitted online.
Historic and Archaeological Resources
Review of the State Historic Preservation Office (SHPO) GIS database indicated that two structures – the
Allen Beavers House and the Jonh M. Freese House, are the only sites within 0.5 mile of the project area.
Neither of these structures should be affected by the proposed project. We understand that you will
complete coordination with the NC State Historic Preservation Office (SHPO).
Avoidance and Minimization
To minimize impacts to waters of the U.S., DENC has proposed to limit the space within which the work
will be conducted to the existing easement. Additionally, construction equipment operating near the
streams/wetlands will be limited to that necessary for pipe replacement and stream restoration activities.
The project has designed to incorporate appropriate erosion and sediment control practices outlined in
the most recent version of the "North Carolina Erosion and Sedimentation Control Planning and Design
Manual” and approved by NCDENR prior to construction.
As proposed, Phase 1 of the project will comply with applicable conditions of NWP No. 3 and GC 4132,
and Phase 2 will comply with NWP No. 12 and WQC No. 4133. Following the repair work, the temporarily-
affected banks of Stream 1 will be restored in accordance with the accompanying construction
documents. We anticipate that construction of the low water crossing at Wetland B/Stream 1 will
minimize future impact from mowing equipment when access to the high ground portion of the
easement is required.
Because the project will not result in permanent stream impacts that exceed 150 linear feet of stream or
wetland impacts that exceed 0.10 acre, compensatory mitigation should not be required.

4h. Explain the purpose of the proposed project:*
The purpose of the project is to replace an exposed segment of the gasline, and also to establish a permanent crossing of a second stream and wetland area north of the exposure
such that mowing equipment can access the area with minimal disturbance.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Phase 1: To replace the segment of exposed gas line, DENC plans to install a new section of pipe belowthe existing streambed at a sufficient depth to help prevent its future exposure.
The work will be conducted using industry -standard mechanized equipment (track hoe and side -boom). Access for construction equipment will be from Wright Road to the south. To
prevent impacts to a stream/wetland located between Wright Road and the exposure, timber mats will be placed across an existing riprap crossing. The mats will then be removed and
the area restored upon project completion.
The pipe replacement work will be conducted "in -the -dry" by constructing coffer dams upstream and downstream of the exposure. A dry workspace will then be established by pumping
clean water from above the upstream coffer dam and around the work area to below the downstream coffer dam. The water will be pumped into a filter bag or dewatering structure sited
in a vegetated area on the west side of the work area, and the water will eventually flow back into the stream. Secondary containment will be utilized to prevent any leakage associated
with the pump.
The new pipe Will be staged on -site and fabricated as a "box -section" that can be efficiently installed by conventional methods. The new pipe Will be placed at a depth approximately five
feet belowthe bed of the stream in order to maintain sufficient separation from the ground surface. Upon installation and tie-in of the new gas line segment, the exposed gas line
segment will be removed. To inhibit the potential for future bank erosion and instability, the streambanks within the easement, Mich are currently eroded and nearly vertical, will then be
graded at a 3:1 slope, seeded with a native riparian seed mix and matted with coir fabric.
Temporary impacts to Wetland A will be required in order to place an equipment mat and establish temporary construction access . Although a small equipment crossing was historically
constructed in WA to accommodate passage of tractors with bush hogs and maintenance equipment, it was considered insufficient for the equipment necessary to repair the exposed
pipe.
Phase 2: Vehicular passage of maintenance equipment through Wetland B cannot be accomplished without significant disturbance to the wetland, and the risk of equipment getting
stuck. To provide more reliable equipment access to this area during future maintenance activities, a new low-water crossing will be constructed at this location. The low water crossing
will be established by installing an articulated concrete block (ACB) mattress across the stream and wetland. The mattress will be embedded such that the stream can continue to flow
through the area. The embedded mattress will provide a firm equipment base, allowing mowing equipment to cross the area with minimal disturbance, and the original grade and contour
of the wetland can be better maintained.
Temporarily affected wetland areas will be restored to the approximate pre -disturbance contours and conditions, seeded with a customized riparian seed mix, and stabilized with coir
matting.

Impacts associated with the permanent wetland/stream crossing have been minimized by establishment of a low-water crossing, thereby maintaining
more of the original grade and contour and eliminating the need for a culvert and associated wetland fill material that would otherwise be necessary.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Appropriate erosion and sediment control measures will be employed during construction and after construction, until such time as the site has
become stabilized. The pipe Will be replaced "in the dry" such that flowing water does not come in contact with the work area. Affected areas vrill be
seeded with a native riparian seed mix, and streambanks will be stabilized with coir fabric.

Event Code: 04EN1000-2020-E-01925
Project Name: M-217 Exposure Repair

Subject:List of threatened and endangered species that may occur in your proposed project
location, and/or may be affected by your proposed project
To Whom It May Concern:
The attached species list identifies threatened, endangered, proposed and candidate species, as
well as proposed and final designated critical habitat, that may occur within the boundary of your
proposed project and/or may be affected by your proposed project. Although not required by
section 7, many agencies request species lists to start the informal consultation process and begin
their fulfillment of the requirements under section 7(c) of the Endangered Species Act (Act) of
1973, as amended (16 U.S.C. 1531 et seq.).
This list, along with other helpful resources, is also available on the U.S. Fish and Wildlife
Service (Service) Asheville Field Office's (AFO) website: https://www.fws.gov/raleigh/species/
cntylist/nc_counties.html. The AFO website list includes “species of concern” species that could
potentially be placed on the federal list of threatened and endangered species in the future. Also
available are:

New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could require modifications of these lists.
Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the Act,
the accuracy of the species lists should be verified after 90 days. This verification can be
completed formally or informally as desired. The Service recommends that verification be
completed by visiting the ECOS-IPaC website or the AFO website (the AFO website dates each
county list with the day of the most recent update/change) at regular intervals during project
planning and implementation for updates to species lists and information. An updated list may be
requested through the ECOS-IPaC system by completing the same process used to receive the
enclosed list or by going to the AFO website.
The purpose of the Act is to provide a means whereby threatened and endangered species and the
ecosystems upon which they depend may be conserved. Under sections 7(a)(1) and 7(a)(2) of the
Act and its implementing regulations (50 CFR 402 et seq.), Federal agencies are required to
utilize their authorities to carry out programs for the conservation of threatened and endangered
species and to determine whether projects may affect threatened and endangered species and/or
designated critical habitat.
A Biological Assessment is required for construction projects (or other undertakings having
similar physical impacts) that are major Federal actions significantly affecting the quality of the
human environment as defined in the National Environmental Policy Act (42 U.S.C. 4332(2)
(c)). For projects other than major construction activities, the Service suggests that a Biological
Evaluation similar to a Biological Assessment be prepared to determine whether the project may
affect listed or proposed species and/or designated or proposed critical habitat. Recommended
contents of a Biological Assessment are described at 50 CFR 402.12 and on our office's website
at https://www.fws.gov/asheville/htmls/project_review/assessment_guidance.html.
If a Federal agency (or their non-federal representative) determines, based on the Biological
Assessment or Biological Evaluation, that listed species and/or designated critical habitat may be
affected by the proposed project, the agency is required to consult with the Service pursuant to
50 CFR 402. In addition, the Service recommends that candidate species, proposed species, and
proposed critical habitat be addressed within the consultation. More information on the
regulations and procedures for section 7 consultation, including the role of permit or license
applicants, can be found in the "Endangered Species Consultation Handbook" at: http://
www.fws.gov/endangered/esa-library/pdf/TOC-GLOS.PDF.
Though the bald eagle is no longer protected under the Endangered Species Act, please be aware
that bald and golden eagles are protected under the Bald and Golden Eagle Protection Act (16
U.S.C. 668 et seq.), and projects affecting these species may require additional consultation (see
https://www.fws.gov/southeast/our-services/permits/eagles/). Wind energy projects should follow
the wind energy guidelines (http://www.fws.gov/windenergy/) for minimizing impacts to
migratory birds (including bald and golden eagles) and bats.
Guidance for minimizing impacts to migratory birds for projects including communications
towers (e.g., cellular, digital television, radio, and emergency broadcast) can be found at: http://
www.fws.gov/migratorybirds/CurrentBirdIssues/Hazards/towers/towers.htm;

Endangered Species Act Species
There is a total of 2 threatened, endangered, or candidate species on this species list.
Species on this list should be considered in an effects analysis for your project and could include
species that exist in another geographic area. For example, certain fish may appear on the species
list because a project could affect downstream species.
IPaC does not display listed species or critical habitats under the sole jurisdiction of NOAA
Fisheries , as USFWS does not have the authority to speak on behalf of NOAA and the
Department of Commerce.
See the "Critical habitats" section below for those critical habitats that lie wholly or partially
within your project area under this office's jurisdiction. Please contact the designated FWS office
if you have questions.
NOAA Fisheries, also known as the National Marine Fisheries Service (NMFS), is an

Migratory Birds
Certain birds are protected under the Migratory Bird Treaty Act and the Bald and Golden Eagle
Protection Act .
Any person or organization who plans or conducts activities that may result in impacts to
migratory birds, eagles, and their habitats should follow appropriate regulations and consider
implementing appropriate conservation measures, as described below.
The Migratory Birds Treaty Act of 1918.
The Bald and Golden Eagle Protection Act of 1940.
50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)
THERE ARE NO FWS MIGRATORY BIRDS OF CONCERN WITHIN THE VICINITY OF YOUR PROJECT
AREA.
Migratory Birds FAQ
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
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 AKN Phenology 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, migrating or present year-round in my
project 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 refer to the following resources: The Cornell Lab
of Ornithology All About Birds Bird Guide, or (if you are unsuccessful in locating the bird of
interest there), the Cornell Lab of Ornithology Neotropical Birds guide. 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:
"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);
"BCC - BCR" birds are BCCs that are of concern only in particular Bird Conservation
Regions (BCRs) in the continental USA; and
"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?
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.

Project Name: M-217 Exposure Repair
Subject:Verification letter for the 'M-217 Exposure Repair' project under the January 5, 2016,
Programmatic Biological Opinion on Final 4(d) Rule for the Northern Long-eared Bat
and Activities Excepted from Take Prohibitions.
Dear Joey Lawler:
The U.S. Fish and Wildlife Service (Service) received on August 11, 2020 your effects
determination for the 'M-217 Exposure Repair' (the Action) using the northern long-eared bat
(Myotis septentrionalis) key within the Information for Planning and Consultation (IPaC)
system. This IPaC key assists users in determining whether a Federal action is consistent with the
activities analyzed in the Service’s January 5, 2016, Programmatic Biological Opinion (PBO).
The PBO addresses activities excepted from "take"[1] prohibitions applicable to the northern
long-eared bat under the Endangered Species Act of 1973 (ESA) (87 Stat.884, as amended; 16
U.S.C. 1531 et seq.).
Based upon your IPaC submission, the Action is consistent with activities analyzed in the PBO.
The Action may affect the northern long-eared bat; however, any take that may occur as a result
of the Action is not prohibited under the ESA Section 4(d) rule adopted for this species at 50
CFR §17.40(o). Unless the Service advises you within 30 days of the date of this letter that your
IPaC-assisted determination was incorrect, this letter verifies that the PBO satisfies and
concludes your responsibilities for this Action under ESA Section 7(a)(2) with respect to the
northern long-eared bat.
Please report to our office any changes to the information about the Action that you submitted in
IPaC, the results of any bat surveys conducted in the Action area, and any dead, injured, or sick
northern long-eared bats that are found during Action implementation. If the Action is not
completed within one year of the date of this letter, you must update and resubmit the
information required in the IPaC key.
08/11/2020 Event Code: 04EN1000-2020-E-01926   2

▪
This IPaC-assisted determination allows you to rely on the PBO for compliance with ESA
Section 7(a)(2) only for the northern long-eared bat. It does not apply to the following ESA-
protected species that also may occur in the Action area:
Schweinitz's Sunflower, Helianthus schweinitzii (Endangered)
If the Action may affect other federally listed species besides the northern long-eared bat, a
proposed species, and/or designated critical habitat, additional consultation between you and this
Service office is required. If the Action may disturb bald or golden eagles, additional
coordination with the Service under the Bald and Golden Eagle Protection Act is recommended.

Action Description
You provided to IPaC the following name and description for the subject Action.
1. Name
M-217 Exposure Repair
2. Description
The following description was provided for the project 'M-217 Exposure Repair':
Repair exposed pipeline.
Approximate location of the project can be viewed in Google Maps: https://www.google.com/
maps/place/35.5380474106949N80.70573052612804W
Determination Key Result
This Federal Action may affect the northern long-eared bat in a manner consistent with the
description of activities addressed by the Service’s PBO dated January 5, 2016. Any taking that
may occur incidental to this Action is not prohibited under the final 4(d) rule at 50 CFR
§17.40(o). Therefore, the PBO satisfies your responsibilities for this Action under ESA Section
7(a)(2) relative to the northern long-eared bat.
Determination Key Description: Northern Long-eared Bat 4(d) Rule
This key was last updated in IPaC on May 15, 2017. Keys are subject to periodic revision.
This key is intended for actions that may affect the threatened northern long-eared bat.
08/11/2020 Event Code: 04EN1000-2020-E-01926   4

The purpose of the key for Federal actions is to assist determinations as to whether proposed
actions are consistent with those analyzed in the Service’s PBO dated January 5, 2016.
Federal actions that may cause prohibited take of northern long-eared bats, affect ESA-listed
species other than the northern long-eared bat, or affect any designated critical habitat, require
ESA Section 7(a)(2) consultation in addition to the use of this key. Federal actions that may
affect species proposed for listing or critical habitat proposed for designation may require a
conference under ESA Section 7(a)(4).

Determination Key Result
This project may affect the threatened Northern long-eared bat; therefore, consultation with the
Service pursuant to Section 7(a)(2) of the Endangered Species Act of 1973 (87 Stat.884, as
amended; 16 U.S.C. 1531 et seq.) is required. However, based on the information you provided,
this project may rely on the Service’s January 5, 2016, Programmatic Biological Opinion on
Final 4(d) Rule for the Northern Long-Eared Bat and Activities Excepted from Take Prohibitions
to fulfill its Section 7(a)(2) consultation obligation.
Qualification Interview
Is the action authorized, funded, or being carried out by a Federal agency?
Yes
Have you determined that the proposed action will have “no effect” on the northern long-
eared bat? (If you are unsure select "No")
No
Will your activity purposefully Take northern long-eared bats?
No
[Semantic] Is the project action area located wholly outside the White-nose Syndrome
Zone?
Automatically answered
No
Have you contacted the appropriate agency to determine if your project is near a known
hibernaculum or maternity roost tree?

Location information for northern long-eared bat hibernacula is generally kept in state
Natural Heritage Inventory databases – the availability of this data varies state-by-state.
Many states provide online access to their data, either directly by providing maps or by
providing the opportunity to make a data request. In some cases, to protect those resources,
access to the information may be limited. A web page with links to state Natural Heritage
Inventory databases and other sources of information on the locations of northern long-
eared bat roost trees and hibernacula is available at www.fws.gov/midwest/endangered/
mammals/nleb/nhisites.html.

RE: M-217 Exposure Repair; 7335-20-083
Dear Joey Lawler:
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, based on the project area mapped with your request, indicates
that there are no records for rare species, important natural communities, natural areas, and/or
conservation/managed areas within the proposed project boundary, or within a one-mile radius of
the project boundary.
Please note that although there may be no documentation of natural heritage elements within or
near the project boundary, it does not imply or confirm their absence; the area may not have been
surveyed. The results of this query should not be substituted for field surveys where suitable habitat
exists. In the event that rare species are found within the project area, please contact the NCNHP so
that we may update our records.
Please also 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 also not be redistributed without
permission.
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,
NC Natural Heritage Program

LICENSE NUMBER: F-0176
UPLAND SEEDING SPECIFICATIONS
DEFINITION:
CONTROLLING RUNOFF AND EROSION ON DISTURBED UPLAND AREAS BY ESTABLISHING PERENNIAL
VEGETATIVE COVER WITH SEED.
PURPOSE
TO REDUCE EROSION AND DECREASE SEDIMENT YIELD FROM DISTURBED AREAS, AND TO PERMANENTLY
STABILIZE SUCH AREAS IN A MANNER THAT IS ECONOMICAL, ADAPTS TO SITE CONDITIONS, AND ALLOWS
SELECTION OF THE MOST APPROPRIATE PLANT MATERIALS.
SEEDBED REQUIREMENTS
ESTABLISHMENT OF VEGETATION SHOULD NOT BE ATTEMPTED ON SITES THAT ARE UNSUITABLE DUE TO
EXCESSIVE SOIL COMPACTION, INAPPROPRIATE SOIL TEXTURE, POOR DRAINAGE, CONCENTRATED OVERLAND
FLOW, OR STEEPNESS OF SLOPE UNTIL MEASURES HAVE BEEN TAKEN TO CORRECT THESE PROBLEMS.
TO MAINTAIN A GOOD STAND OF VEGETATION, THE SOIL MUST MEET CERTAIN MINIMUM REQUIREMENTS AS A
GROWTH MEDIUM. THE EXISTING SOIL SHOULD HAVE THESE CRITERIA:
·ENOUGH FINE-GRAINED (SILT AND CLAY) MATERIAL TO MAINTAIN ADEQUATE MOISTURE AND NUTRIENT
SUPPLY (AVAILABLE WATER CAPACITY OF AT LEAST .05 INCHES WATER TO 1 INCH OF SOIL).
·SUFFICIENT PORE SPACE TO PERMIT ROOT PENETRATION.
·SUFFICIENT DEPTH OF SOIL TO PROVIDE AN ADEQUATE ROOT ZONE. THE DEPTH TO ROCK OR
IMPERMEABLE LAYERS SUCH AS HARDPANS SHOULD BE 12 INCHES OR MORE, EXCEPT ON SLOPES STEEPER
THAN 2:1 WHERE THE ADDITION OF SOIL IS NOT FEASIBLE.
·A FAVORABLE PH RANGE FOR PLANT GROWTH, USUALLY 6.0 - 6.5.
·FREE FROM LARGE ROOTS, BRANCHES, STONES, LARGE CLODS OF EARTH, OR TRASH OF ANY KIND. CLODS
AND STONES MAY BE LEFT ON SLOPES STEEPER THAN 3:1 IF THEY ARE TO BE HYDRO SEEDED.
IF ANY OF THESE CRITERIA ARE NOT MET - I.E., IF EXISTING SOIL IS TOO COARSE, DENSE, SHALLOW OR ACIDIC
TO FOSTER VEGETATION - SPECIAL AMENDMENTS ARE REQUIRED. THE SOIL CONDITIONERS DESCRIBED BELOW
MAY BE BENEFICIAL OR, PREFERABLY, TOPSOIL MAY BE APPLIED.
SEEDBED PREPARATION
INSTALL NECESSARY MECHANICAL EROSION AND SEDIMENTATION CONTROL PRACTICES BEFORE SEEDING,
AND COMPLETE GRADING ACCORDING TO THE APPROVED PLAN.
LIME AND FERTILIZER NEEDS SHOULD BE DETERMINED BY SOIL TESTS. DIRECTIONS, SAMPLE CARTONS, AND
INFORMATION SHEETS ARE AVAILABLE THROUGH COUNTY AGRICULTURAL EXTENSION OFFICES. TESTING IS
ALSO DONE BY COMMERCIAL LABORATORIES.
WHEN SOIL TESTS RESULTS ARE NOT AVAILABLE, FOLLOW RATES SUGGESTED IN THE SEEDING SPECIFICATIONS
TABLES.
APPLY LIME AND FERTILIZER EVENLY AND INCORPORATE INTO THE TOP 4-6 INCHES OF SOIL BY DISKING OR
OTHER SUITABLE MEANS. OPERATE MACHINERY ON THE CONTOUR. WHEN USING A HYDRO SEEDER, APPLY
LIME AND FERTILIZER TO A ROUGH, LOOSE SURFACE.
ROUGHEN SURFACES PRIOR TO SEEDING.
COMPLETE SEEDBED PREPARATION BY BREAKING UP LARGE CLODS AND RAKING INTO A SMOOTH, UNIFORM
SURFACE (SLOPES LESS THAN 3:1). FILL IN OR LEVEL DEPRESSIONS THAT CAN COLLECT WATER. BROADCAST
SEED INTO A FRESHLY LOOSENED SEEDBED THAT HAS NOT BEEN SEALED BY RAINFALL.
SEEDING
SEEDING DATES GIVEN IN THE SEEDING MIXTURE SPECIFICATIONS ARE CONSIDERED TO BE "BEST" OR
"POSSIBLE". SEEDINGS PROPERLY CARRIED OUT WITHIN THE DATE RANGES GIVEN HAVE A HIGH PROBABILITY
OF SUCCESS. IT IS ALSO POSSIBLE TO HAVE SATISFACTORY ESTABLISHMENT WHEN SEEDING OUTSIDE THESE
DATES. HOWEVER, AS YOU DEVIATE FROM THEM, THE PROBABILITY OF FAILURE INCREASES RAPIDLY. SEEDING
ON THE LAST DATE SHOWN MAY REDUCE CHANCES OF SUCCESS BY 30-50%. ALWAYS TAKE THIS INTO
ACCOUNT IN SCHEDULING LAND-DISTURBING ACTIVITIES.
USE CERTIFIED SEED FOR PERMANENT SEEDING.
LABELING OF NON-CERTIFIED SEED IS ALSO REQUIRED BY LAW. LABELS CONTAIN IMPORTANT INFORMATION
ON SEED PURITY, GERMINATION, AND PRESENCE OF WOOD SEEDS. SEEDS MUST MEET STATE STANDARDS FOR
CONTENT OF NOXIOUS WEEDS. DO NOT ACCEPT SEED CONTAINING "PROHIBITED" NOXIOUS WEED SEED.
INOCULATE LEGUME SEED WITH THE RHIZOBIUM BACTERIA APPROPRIATE TO THE SPECIES OF LEGUME.
APPLY SEED UNIFORMLY WITH A CYCLONE SEEDER, DROP-TYPE SPREADER, DRILL, CULTIPACKER SEEDER, OR
HYDRO SEEDER ON A FIRM, FRIABLE SEEDBED.
WHEN USING A DRILL OR CULTIPACKER SEEDER, PLANT SMALL GRAINS NO MORE THAN 1 INCH DEEP, GRASSES
AND LEGUMES NO MORE THAN 1/2 INCH. EQUIPMENT SHOULD BE CALIBRATED IN THE FIELD FOR THE DESIRED
SEEDING RATE.
WHEN USING BROADCAST-SEEDING METHODS, SUBDIVIDE THE AREA INTO WORKABLE SECTIONS AND
DETERMINE THE AMOUNT OF SEED NEEDED FOR EACH SECTION. APPLY ONE-HALF THE SEED WHILE MOVING
BACK AND FORTH ACROSS THE AREA, MAKING A UNIFORM PATTERN: THEN APPLY THE SECOND HALF IN THE
SAME WAY, BUT MOVING AT RIGHT ANGLES TO THE FIRST PASS.
MULCH ALL PLANTINGS IMMEDIATELY AFTER SEEDING.
HYDRO SEEDING
SURFACE ROUGHENING IS PARTICULARLY IMPORTANT WHEN HYDRO SEEDING, AS A ROUGHENED SLOPE WILL
PROVIDE SOME NATURAL COVERAGE FOR LIME, FERTILIZER, AND SEED. THE SURFACE SHOULD NOT BE
COMPACTED OR SMOOTH. FINE SEEDBED PREPARATION IS NOT NECESSARY FOR HYDRO SEEDING
OPERATIONS: LARGE CLODS, STONES, AND IRREGULARITIES PROVIDE CAVITIES IN WHICH SEEDS CAN LODGE.
RATE OF WOOD FIBER (CELLULOSE) APPLICATION SHOULD BE AT LEAST 4,000 LB/ACRE.
APPLY LEGUME INOCULANTS AT FOUR TIMES THE RECOMMENDED RATE WHEN ADDING INOCULANT TO A
HYDRO SEEDER SLURRY.
IF A MACHINERY BREAKDOWN OF 1/2 TO 2 HOURS OCCURS, ADD 50% MORE SEED TO THE TANK, BASED ON
THE PROPORTION OF THE SLURRY REMAINING. THIS SHOULD COMPENSATE FOR DAMAGE TO SEED. BEYOND 2
HOURS, A FULL RATE OF NEW SEED MAY BE NECESSARY.
LIME IS NOT NORMALLY APPLIED WITH A HYDRAULIC SEEDER BECAUSE IT IS ABRASIVE. IT CAN BE BLOWN
ONTO STEEP SLOPES IN DRY FORM.
MAINTENANCE
GENERALLY, A STAND OF VEGETATION CANNOT BE DETERMINED TO BE FULLY ESTABLISHED UNTIL SOIL COVER
HAS BEEN MAINTAINED FOR ONE FULL YEAR FROM PLANTING. INSPECT SEEDED AREAS FOR FAILURE AND MAKE
NECESSARY REPAIRS AND RESEEDINGS WITHIN THE SAME SEASON, IF POSSIBLE.
RESEEDING--IF A STAND HAS INADEQUATE COVER, RE-EVALUATE CHOICE OF PLANT MATERIALS AND
QUANTITIES OF LIME AND FERTILIZER. RE-ESTABLISH THE STAND AFTER SEEDBED PREPARATION OR OVER-
SEED THE STAND. CONSIDER SEEDING TEMPORARY, ANNUAL SPECIES IF THE TIME OF YEAR IS NOT
APPROPRIATE FOR PERMANENT SEEDING.
IF VEGETATION FAILS TO GROW, SOIL MUST BE TESTED TO DETERMINE IF ACIDITY OR NUTRIENT IMBALANCE IS
RESPONSIBLE.
FERTILIZATION--ON THE TYPICAL DISTURBED SITE, FULL ESTABLISHMENT USUALLY REQUIRES RE-FERTILIZATION
IN THE SECOND GROWING SEASON. FINE TURF REQUIRES ANNUAL MAINTENANCE FERTILIZATION. USE SOIL
TESTS IF POSSIBLE OR FOLLOW THE GUIDELINES GIVEN FOR THE SPECIFIC SEEDING MIXTURE.
