Subject: Section 401 Water Quality Pre -Construction Notification
Colonial Pipeline Company Maintenance
Rowan County, North Carolina
Corblu Project No. 02-041901- Exposure Line 2
To whom it may concern:
On behalf of our client, Colonial Pipeline Company's (CPC), Corblu Ecology Group, LLC (Corblu) is
pleased to submit this Section 401 water quality Pre -Construction Notification (PCN) for the
required exposed pipeline maintenance work for CPC's Line 2. The pipeline exposure is located
northwest of the Pinevale Drive and Lumen Christi Lane intersection in Rowan County, North
Carolina (35.704961, -80.509357; Figure 1). Based on our evaluation of the subject site, we
believe that the temporary and permanent disturbances to waters of the U.S. associated with this
activity are authorized by the U.S. Army Corps of Engineers (USACE) under a combination of
Nationwide Permit (NWP) Nos. 3 (a) and (c) — Maintenance. This NWP does not require
notification of the USACE prior to initiation of the work; however, it has been determined that
written approval is required from the North Carolina Department of Environmental Quality (DEQ)
for Section 401 Water Quality Certification prior to the initiation of work.
Background
Recent high flow events from significant precipitation associated with Hurricane Florence has
resulted in significant stream bed and bank erosion within the unnamed perennial tributary to Jump
and Run Branch within CPC's right-of-way (ROW), exposing CPC's Line 2 (Photograph Nos. 1 and
2). The exposure and lack of surface pipeline protection at this project location has resulted in
conditions that leave the pipeline vulnerable to potential damages. Further, these conditions are
not consistent with CPC's or regulatory requirements for pipeline protection.
Section 401 Water Quality Pre -Construction Notification November 13, 2018
Colonial Pipeline Company — Line 2 Exposure Corblu Project No. 02-041901 — Rowan Co. NC
Proposed Activities in Jurisdictional Waters
The proposed pipeline maintenance activity will include permanent and temporary impacts to an
unnamed perennial stream totaling 99 linear feet [approximately 89 linear feet (pre -cast revetment
mats and rip rap) and 10 linear feet (temporary dam and pump)], respectively. Specifically, CPC
proposes to permanently place approximately 34 linear feet of Submar matting and 55 linear feet of
rip rap which will provide the required protective cover over Line 2. Temporary disturbances to the
perennial stream will include approximately 10 linear feet of temporary workspace (dam and pump)
to conduct maintenance activities "in -the -dry". The proposed maintenance location will be
accessed through CPC's existing, mowed, and maintained ROW from Lumen Christi Lane (Figure
3). CPC intends to inspect the exposed pipeline and replace the required protective cover over the
pipeline through the use of pre -cast revetment mats. To re-establish the protective cover CPC
intends to conduct the following: 1) excavate the pipeline at the exposure on Line 2; 2) inspect and
make repairs to Line 2 as necessary; 3) backfill the excavation area; and 4) restore the stream to
approximate pre -Hurricane Florence contours and elevations over Line 2 using returned excavated
material and key pre -cast revetment mats into the stream bed and bank in a manner that maintains
stream grade and flow conditions (Appendix A).
To minimize sedimentation to the unnamed perennial stream during the above-mentioned
maintenance activity, dams constructed of sand bags, steel plates, or water -inflatable plastic dams
will be temporarily placed upstream of the maintenance area. The stream flow will be pumped
around the maintenance area, discharging immediately downstream via an energy dissipater to
prevent stream scour. The pump used will be sufficiently sized to accommodate the anticipated
stream flow (Appendix B).
The temporarily excavated soils will be stored within the adjacent upland area and returned to the
excavated trench, and approximate pre -hurricane contours will be restored following completion of
the maintenance activity. It is our understanding once the required protective pipeline cover (pre-
cast revetment mats) is keyed into the streambed in a manner that maintains existing grade and
flow conditions of the stream, the temporary dams will be removed, and normal streamflow will be
restored. Rip rap used to stabilize the pre -cast revetment matting in the stream bed will be placed
so the finished top elevation of the rip rap does not exceed that of the original stream bed, and any
rip rap utilized for bank stabilization will be placed on an erosion control blanket (geotextile fabric).

CPC's standard erosion control practices will be employed (Appendix C). Specifically, the disturbed
areas along the stream bank will be revegetated with a grass seed mix and stabilized with straw
and silt fence.
Corblu respectfully requests 401 Water Quality Certification for the required preventative pipeline
maintenance and the unavoidable impacts to 99 linear feet of perennial stream (34 linear feet of
Submar matting, 55 linear feet of rip rap and 10 linear feet of temporary workspace) within CPC's
existing, mowed, and maintained ROW (Appendix A). The appropriate figures and photographs
are enclosed for your review.

CPC SOIL EROSION AND SEDIMENT CONTROL PLAN
Colonial Pipeline Company
Soil Erosion and Sediment Control Plan
For
Pipeline Maintenance Activities
Objective
Disturbed areas are to be restored as close as practical to their original contours and
conditions so that once vegetation is reestablished, erosion will be reduced to the same
or lower level that existed prior to disturbance.
Description
This section defines the soil erosion and sediment control measures that Colonial
Pipeline Company will implement during and after inspection and repairs of the pipeline
are complete. The objectives of this plan are to establish general guidelines for
controlling erosion and sedimentation and to specify criteria for sensitive or particularly
susceptible soil areas. The plan incorporates measures to control erosion and
sedimentation, including minimizing cover removal, limiting the time of exposure,
limiting the flow of water onto the disturbed right-of-way, and filtering or settling out
sediment from water flowing from the right-of-way.
The primary objective of the soil erosion and sediment control plan is to reduce the area
and duration of soil disturbance and reestablish permanent vegetation as soon after
construction as possible, thereby minimizing long-term erosion and sedimentation.
Some erosion is inevitable during construction; however, the plan includes measures to
reduce erosion to the minimum practical.
Colonial Pipeline Company plans to reduce soil erosion and provide sediment control
during the repair of the pipeline at the project site by incorporating the following
measures:
• Water pumped from the construction area as part of the dewatering operation
from the excavation will be filtered through silt filtration bags and discharged to
a well -vegetated area.
• All work will be confined within the existing right-of-way. Staked hay bales and silt
fence will be installed around the worksite and maintained until vegetation is established.
Proper controls will be added ifnecessary during construction.
• All terms and conditions within Nationwide Permit 3 will be followed.
• Erosion control measures will be installed prior to conducting any soil disturbing
activities associated with the pipeline maintenance activity.
• Clearing of vegetation will be kept to an absolute minimum and confined to the
existing pipeline easement area. The easement area is 50 feet in width and devoid
oflarge trees. The right of way is vegetated with undergrowth grasses and other
short vegetation.
• Vegetation will be reestablished within disturbed areas and along stream banks
as soon as possible upon completion of work. Disturbed areas will be seeded
with a wetland seed mixture
• All erosion and sediment control measures will be inspected every two weeks at a
minimum and after every significant rainfall event of 0.5 inch or more until
disturbed areas have been stabilized. Identified damages to control measures
must be repaired immediately.
Refuse and Waste Disposal
Colonial's representative will not allowthe Contractor to discard any litter, including
paper, bottles, cans, rags, sacks, welding rod stubs, fuel, crankcase draining, coating
materials, equipment, and junk pipe in the ditch or along the right-of-way. All refuse
mustbe collected and disposed in accordance with company specifications. Personnel
will be instructed regarding the correct procedure for waste disposal.
Maintenance/Inspection Procedures
The following inspection and maintenance practices will be implemented to maintain
erosion andsediment controls:
1. All control measures will be inspected every two weeks at a minimum and following
any storm event of 0.5 inch or greater.
2. All control measures will be maintained in good working order. If a repair is
necessary, it will be initiated within 24 hours ofthe report.
3. Built-up sediment will be removed from silt fences when it has reached one-third the
height ofthe fence.
4. Silt fences will be inspected for depth of sediment, tears, secure attachment of the
fabric to the fence posts, and firm placement of the fence posts in the ground.
5. Temporary and permanent seeding and planting will be inspected for bare spots,
washouts, and healthy growth.
6. Colonial Pipeline Company will select individuals to be responsible for inspections,
maintenance and repair activities, and completion of the inspection and
maintenance report. Personnel selected for inspection and maintenance
responsibilities will receive training from Colonial Pipeline Company or its
representative. Personnel must be trained in all practices necessary for maintaining
the erosion and sediment controls used on-site.

Project Description
3a.
Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
The work is to be conducted within CPC's existing mowed and maintained right-of-way (ROW). The stream has
experienced significant erosion of the left bank (outside bend) from Hurricane Florence (i.e., heavy rainfall) which is the
cause of the pipeline exposure.
3b.
List the total estimated acreage of all existing wetlands on the property:
N/A — No wetlands present within project area.
3c.
List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
Approximately 125 linear feet of perennial stream
3d.
Explain the purpose of the proposed project:
Significant precipitation associated with Hurricane Florence has resulted in stream bed and bank erosion to the unnamed
perennial stream within CPC's ROW exposing CPC's Line 2. CPC proposes to inspect the exposed line and replace the
required protective cover over the pipeline using pre -cast revetment mats.
3e.
Describe the overall project in detail, including the type of equipment to be used:
CPC intends to inspect the exposed pipeline and replace the required protective cover over the pipeline through the use
of pre -cast revetment mats. To re-establish the protective cover CPC intends to conduct the following: 1) excavate the
exposure on Line 2; 2) inspect and make repairs to Line 2 as necessary; 3) backfill the excavation area; and 4) restore
the stream to approximate pre -erosion contours and elevations using returned excavated material and revetment mats
keyed into the stream bed and bank in a manner that maintains grade and stream flow conditions.
To minimize sedimentation to the unnamed perennial stream during the above-mentioned maintenance activity, dams
constructed of sand bags, steel plates, or water -inflatable plastic dams will be temporarily placed upstream of the
maintenance area. The stream flow will be temporarily pumped around the maintenance area, discharging immediately
downstream via an energy dissipater to prevent stream scour. The pump used will be sufficiently sized to accommodate
the anticipated stream flow.
The temporarily excavated soils will be stored within the adjacent upland areas and returned to the excavated trenches,
and approximate pre -erosion contours will be restored following completion of the maintenance activity. It is our
understanding once the required protective pipeline cover (pre -cast revetment mats) is keyed into the streambed in a
manner that maintains existing grade and stream flow, the temporary dams will be removed, and normal streamflow
restored. Rip rap used to stabilize the revetment mats within the stream bed will be placed so the finished top elevation of
the rip rap does not exceed that of the original stream bed, and any rip rap utilized for bank stabilization will be placed on
filter cloth as required. CPC's standard erosion control practices will be employed. Specifically, the disturbed areas along
the stream bank will be revegetated with a grass seed mix and stabilized with straw and silt fence.

Impact Justification and Mitigation
1.
Avoidance and Minimization
1a.
Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Significant precipitation associated with Hurricane Florence has resulted in stream bed and bank erosion in the unnamed
perennial stream within CPC's ROW, exposing CPC's Line 2. The exposure and lack of surface pipeline protection at this
project location has resulted in conditions that may lead to potential damage to CPC's petroleum pipeline Line 2. Further,
these conditions are not consistent with CPC's or regulatory requirements for pipeline protection. Therefore, CPC is
required to conduct the work for the safety of the pipeline (unavoidable work).
b.
Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
CPC will only conduct work within their mowed and maintained ROW, thereby minimizing impacts to the greatest extent
possible.

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 etseq.).
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: hgps://www.fws. ovg /raleigh/species/
cniylist/nc—counties.html. list/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/htmis/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/endanizered/esa-libraI3L/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/windenergyo 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://

We appreciate your concern for threatened and endangered species. The Service encourages
Federal agencies to include conservation of threatened and endangered species into their project
planning to further the purposes of the Act. Please include the Consultation Tracking Number in
the header of this letter with any request for consultation or correspondence about your project
that you submit to our office.

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.

Migratory Birds
Event Code: 04EN1000-2019-E-00052
Certain birds are protected under the Migratory Bird Treaty Act! and the Bald and Golden Eagle
Protection Act2.
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.
1. The Migratory Birds Treaty Act of 1918.
2. The Bald and Golden Eagle Protection Act of 1940.

The birds listed below are birds of particular concern either because they occur on the USFWS
Birds of Conservation Concern (BCC) list or warrant special attention in your project location.
To learn more about the levels of concern for birds on your list and how this list is generated, see
the FAQ below. This is not a list of every bird you may find in this location, nor a guarantee that
every bird on this list will be found in your project area. To see exact locations of where birders
and the general public have sighted birds in and around your project area, visit the E -bird data
mapping tool (Tip: enter your location, desired date range and a species on your list). For
projects that occur off the Atlantic Coast, additional maps and models detailing the relative
occurrence and abundance of bird species on your list are available. Links to additional
information about Atlantic Coast birds, and other important information about your migratory
bird list, including how to properly interpret and use your migratory bird report, can be found
below.
For guidance on when to schedule activities or implement avoidance and minimization measures
to reduce impacts to migratory birds on your list, click on the PROBABILITY OF PRESENCE
SUMMARY at the top of your list to see when these birds are most likely to be present and

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 report.
Probability of Presence (E)
Each green bar represents the bird's relative probability of presence in the lOkm 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 them, the probability of presence of the Spotted Towhee in week 12 is
0.25.
2. To properly present the pattern of presence across the year, the relative probability of
presence is calculated. This is the probability of presence divided by the maximum
probability of presence across all weeks. For example, imagine the probability of presence
in week 20 for the Spotted Towhee is 0.05, and that the probability of presence at week 12
(0.25) is the maximum of any week of the year. The relative probability of presence on
week 12 is 0.25/0.25 = 1; at week 20 it is 0.05/0.25 = 0.2.
3. The relative probability of presence calculated in the previous step undergoes a statistical
conversion so that all possible values fall between 0 and 10, inclusive. This is the
probability of presence score.
Breeding Season (■)
10/18/2018 Event Code: 04EN 1 000-2019-E-00052 3
Yellow bars denote a very liberal estimate of the time -frame inside which the bird breeds across
its entire range. If there are no yellow bars shown for a bird, it does not breed in your project
area.
Survey Effort (1)
Vertical black lines superimposed on probability of presence bars indicate the number of surveys
performed for that species in the lOkm grid cell(s) your project area overlaps. The number of
surveys is expressed as a range, for example, 33 to 64 surveys.
No Data (—)
A week is marked as having no data if there were no survey events for that week.
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.

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
B( CCS 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, bandins,
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 E -bird Explore Data 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
10/18/2018 Event Code: 04EN 1 000-2019-E-00052
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:
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?
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
10/18/2018 Event Code: 04EN1000-2019-E-00052
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.
