Subject: Section 401 Water Quality Pre-Construction Notification
Colonial Pipeline Company Maintenance
Chatham County, North Carolina
Corblu Project No. 02-041901-338 -Line 24 Exposure
To Whom It May Concern:
On behalf of our client, Colonial Pipeline Company(CPC), Corblu Ecology Group, LLC(Corblu) is pleased
to submit this Section 401 water quality Pre-Construction Notification (PCN)for preventative maintenance
on Line 24 for a petroleum pipeline exposure, needed to restore the required pipeline protective cover
within an unnamed intermittent stream and emergent wetland in CPC's right-of-way (ROW). The pipeline
exposure is located within CPC's existing and maintained ROW southeast of the Lewter Shop Road and
North Carolina Highway 751 (NC-751) intersection in Chatham County, North Carolina (35.77485, -
78.95706; Figure 1; Appendix A).
Based on our evaluation of the subject site, we believe that disturbances to waters of the U.S. associated
with this maintenance activity are authorized by the U.S. Army Corps of Engineers (USACE) under
Nationwide Permit (NWP) No. 3 (a) and (c) —Maintenance. This NWP does not require notification to the
USACE prior to initiation of the work as the maintenance activities are less than 0.02-acre within the
intermittent stream (i.e., 0.004-acre); however, disturbance to the intermittent streambed exceeds 40 LF,
which requires 401 Water Quality Certification from the North Carolina Department of Environmental
Quality (DEQ) prior to the initiation of the proposed work.
Background
Corblu inspected the above referenced exposure maintenance location for the presence of jurisdictional
waters of the U.S. on January 26, 2022. Jurisdictional features (one unnamed intermittent stream and
one emergent wetland [W1]) were observed within the project area (Photograph Nos. 1-3; Figure 2).

Section 401 Water Quality Pre-Construction Notification May 25,2022
Colonial Pipeline Company—Line 24 Exposure Corblu Project No.02-041901-338—Chatham County, North Carolina
Additionally, one emergent wetland (W2) was observed west and outside of the maintenance location
(Photograph No. 4; Figure 2).
Recent significant precipitation events have resulted in bed and bank erosion in the unnamed intermittent
stream within CPC's ROW, exposing Line 24. The erosion at this location resulted in conditions that have
left Line 24 vulnerable to potential damage. Further, these conditions are not consistent with CPC's or
the U.S. Department of Transportation's (USDOT) regulatory requirements for pipeline protection.
CPC is committed to operating their pipelines and support facilities in a manner that protects the safety
of the public, the environment, and its workforce. The proposed preventative pipeline maintenance is a
component of CPC's ongoing Integrity Management Program (IMP) as required by the U.S. Department
of Transportation (USDOT) requirements [49 CFR Part 195 — "Pipeline Safety: Pipeline Integrity in High
Consequence Areas (Hazardous Liquid Operators with 500 or More Miles of Pipeline); Final Rule."] The
IMP provides an important means of achieving spill-free, error-free operations. The purpose of the IMP
is to improve/maintain the integrity of CPC's system — including CPC's pipelines, facilities, equipment,
tanks, and delivery lines.
CPC's IMP and the referenced USDOT regulations include prescriptive requirements for inspection of
pipeline systems and requires excavation and repair of certain pipeline defects according to specific
schedules and regulatory guidelines. It should be noted that USDOT has completed an Environmental
Assessment (EA) under the National Environmental Policy Act (NEPA) concerning repairs that an
operator would have to make to its pipeline following an integrity assessment. The EA and corresponding
Finding of No Significant Impact concluded that these actions would not significantly affect the quality of
the human environment (Docket No. RSPA-00-6355).
In accordance with 49 CFR § 195.401 and CPC's IMP, CPC must take prompt action to address
anomalous conditions,to include pipeline exposures and shallow cover areas that are discovered through
the integrity assessment process. CPC must, in maintaining its pipeline systems, ensure that repairs are
made in a safe and timely manner and are conducted in a way so as to prevent damage to persons,
property, and the environment. Additionally, CPC's IMP follows USDOT's requirements with respect to
addressing possible unsafe conditions; specifically, the USDOT - Pipeline and Hazardous Materials
Safety Administration's (PHMSA) Interpretation Response No. PI-84-0103 which explains with respect to
the regulatory provisions of 49 CFR Part 192, Subpart M and Part 195, Subpart F, whenever an operator
discovers any condition that could adversely affect the safe operation of its pipeline system, the operator
must correct the condition within a reasonable time.

Colonial Pipeline Company—Line 24 Exposure Corblu Project No.02-041901-338—Chatham County, North Carolina
Proposed Activities in Jurisdictional Waters
The maintenance location will be accessed through CPC's existing, mowed, and maintained ROW from
NC-751 (Figure 3). Temporary prefabricated mats will be used to cross W1 and W2 within CPC's ROW
to access the maintenance location and operate equipment (Figure 3; Appendix B). Based on our
discussions with CPC's maintenance inspector, it is our understanding that CPC intends to inspect Line
24 and replace the required minimal protective cover over the pipeline using Submar revetment mats and
riprap to remediate the streambank erosion associated with the pipeline exposure (Appendix A). To re-
establish the required pipeline protective cover, CPC intends to conduct the following: 1) excavate Line
24; 2) inspect and make repairs to Line 24, as necessary; 3) grade the site for mat installation; 4) install
riprap above and below the revetment mats, which will be "keyed" into the streambed/banks and abutting
wetland in a manner that will re-establish pre-erosional contours and elevations of the streambed,
providing the required pipeline cover and maintain existing flow conditions; and 5) re-seed with native
wetland seed mix and straw the surrounding disturbed area (Appendix A).
To minimize sedimentation to the unnamed intermittent stream during the above-mentioned maintenance
activity, dams constructed of sandbags, steel plates, or water-inflatable plastic dams will be temporarily
placed upstream of the maintenance area to conduct maintenance activities "in-the-dry". The stream flow
will be pumped around the maintenance area, discharging immediately downstream via an energy
dissipater to prevent stream scour. The pump(s) used will be sufficiently sized to accommodate the
anticipated stream flow(Appendix C).The excavated ordered soils will be temporarily stored on geotextile
(or similar) material in the adjacent upland area within CPC's ROW.
Rip rap will be placed on an erosion control blanket (geotextile fabric) to stabilize the revetment mats in
a manner where the finished top elevation of the riprap does not exceed that of the streambed elevation.
Once the required minimal protective pipeline cover (pre-cast revetment mats) is keyed into the
streambed in a manner that maintains existing grade, low and normal flow conditions of the stream, the
temporary dams will be removed, and normal streamflow will be restored (Appendix A).
We understand CPC's standard erosion control practices will be employed (Appendix D). Specifically, as
stated above the disturbed areas along the stream banks and emergent wetland will be reseeded with
native wetland seed mix and straw to stabilize the recently disturbed soils.
The proposed maintenance activity includes work within the unnamed intermittent stream and an
emergent wetland abutting the stream banks on both sides. Specifically, the above-described
maintenance activity will require unavoidable impacts to approximately 119 linear feet(LF) of intermittent
stream [59 LF (0.004-acre) of permanent impacts (riprap and revetment mats) and 60 LF of temporary

workspace] and 0.0238-acre of W1 [0.0108 of permanent impacts (riprap and revetment mats)and 0.013-
acre of temporary grading] within CPC's existing and maintained ROW.
Corblu respectfully requests 401 Water Quality Certification for the required maintenance activities and
the unavoidable minimal permanent impacts to approximately 59 LF (0.004-acre)of unnamed intermittent
stream and 0.0108-acre of emergent wetland W1 within CPC's existing and maintained ROW(Appendix
A). The appropriate figures and photographs are enclosed for your review.

Summary and Conclusion
In summary, the above-described pipeline maintenance activity will result in unavoidable permanent
impacts to approximately 59 LF (0.004-acre) and temporary impacts to 60 LF of intermittent stream, as
well as 0.0108-acre of permanent impact and 0.013-acre of temporary impact to emergent wetland as
authorized under the USACE NWP No. 3(a) and (c). The project was designed to avoid and minimize
stream and wetland impacts to the maximum extent practicable and represents the least environmentally
damaging, practicable alternative that satisfies the project purpose for preventative pipeline maintenance
and protection.

APPENDIX D
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

of large 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 allow the 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
must be 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 of the report.
3. Built-up sediment will be removed from silt fences when it has reached one-third the
height of the 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.

detail of the information will often determine the expeditiousness of the review. The following is
a checklist of the types of pertinent information required at a minimum:
Maps and Plans:
0 The most recent version of the 1:24,000 USGS Topographic Map - Please cleanly draw or
delineate the site boundaries on the topographic map.

Version 4.2
Updated January 31, 2022
0 The most recent version of the bound and published County NRCS Soil Survey Map -
(required for projects within the Neuse River Basin, Tar-Pamlico River Basin, Randleman
Lake Watershed and the Catawba River Basin, also recommended for all projects) - Please
clearly delineate the site boundaries, etc. on the map. If the delineation obscures any of the
features, it is recommended that a clean copy be provided. Copies of the current soil survey
and/or soil survey map sheets can be obtained from the local NRCS County Office
(http://www.nc.nres.usda.gov/). GIS soil layers are not acceptable.
0 Vicinity map - Please clearly mark the location and approximate boundaries of the property
and project on the map. Please indicate north arrow and scale. Please include applicable road
names or State Road numbers.
El The Site Plan - The most critical map to be provided is the site plan. The following is the
minimum list of plans that are typically needed.
0 Pre-construction/Pre-existing conditions - This sheet (or sheets) must include:
• All jurisdictional and non-jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Topographic contours with elevations
• Any existing structures and impervious areas
• Existing utility lines and easements
• Existing roads, culverts, and other pertinent features
• North arrow and the scale (1":50' scale is recommended).
Q Proposed conditions - This sheet (or sheets) must include:
• All jurisdictional and non-jurisdictional wetland, stream, water features, State regulated
buffers (delineated into Zones 1 and 2)
• Lot layout (if a subdivision or commercial development is proposed) - lots must be
developable without further impacts to jurisdictional and non-jurisdictional wetlands,
streams, water features, and State regulated buffers. Building envelopes must be provided
when streams, wetlands, riparian buffers, or water features exist on a lot
• All built-out structures and impervious cover
• Final grading contours with elevations
• All utilities and easements (including septic fields on all lots within 100 feet of stream,
wetland, or water features - if applicable)
• Impacted areas — these should correspond with the Impact numbers listed on your PCN
form.
N/A Drainage Plans - Final drainage plans must include the following:
• Locations and pertinent elevations and sizes of the stormwater collection system and
drainage ways
• All inlets and outlets must also be shown with pertinent elevations (All outlets to wetlands
must be at a non-erosive velocity, generally less than 2 ft/sec during the peak flow from
the 10-yr storm)
• Scaled stormwater BMPs must also be indicated as required by DWR rules and policies
• In certain cases (see Section F of PCN form), final stormwater management plan must
also be provided (see Stormwater Management Plan Checklist)
0 Proposed Impacts-All impacts to jurisdictional and non-jurisdictional wetland, stream, water
features, and State regulated buffers must be shown and labeled on the site plans at a scale

Version 4.2
Updated January 31, 2022
no smaller than 1" = 50'. All excavation, fill, flooding, stabilization, and other impacts that will
be conducted in or near jurisdictional and non-jurisdictional wetland, stream, water features,
and State regulated buffers must be indicated. Please provide cross sectional details showing
the provisions for aquatic life passage (burial of culvert 20% for culverts <_ 48 inches, and 1-
foot for culverts > 48 inches).
Wetland Impacts:
Precise grading and final elevation contours must be provided. Existing vegetation
and any clearing must be specified.
N/A All subsurface utility lines must indicate the location of anti-seep collars.
Construction detail for anti-seep collars must be provided.
N/A Roadway or other crossings of riparian wetlands may require floodway culverts to
maintain existing hydrological conditions.
Plans should show that the hydrology of remaining wetlands on the site will be
maintained.
Stream Impacts:
El Stream impacts must be clearly shown on the plans. The centerline as well as the
banks of the stream must be surveyed or located by GPS for the portion of the
stream to be impacted.
N/A The inlet and the outlet of all culverts should be aligned with the stream as much
as possible. Inlet and outlet elevations and streambed elevations should be
indicated. Any inlet or outlet protection must be shown and enumerated on the
impact map(s).
N/A For bottomless culverts or other spans, a vertical cross section should be
provided that shows the minimum distance from each span to each stream bank,
the stream cross section, the height of the span above the stream and the
minimum distance from the edge of each footer to each stream bank.

4. Project Description and History
4a. 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 site is comprised of CPC's existing mowed and maintained petroleum pipeline right-of-way (ROW).

4h. Explain the purpose of the proposed project: *
Significant precipitation events have created increased stream flows resulting in bed and bank erosion in the
unnamed intermittent stream within CPC's ROW, exposing Line 24. The erosion at this location resulted in
conditions that have left Line 24 vulnerable to potential damage. Further, these conditions are not consistent with
CPC's or the U.S. Department of Transportation's (USDOT) regulatory requirements for pipeline protection. CPC
proposes to replace the protective cover over the line using Submar revetment mats and riprap. These actions
serve to protect the existing pipeline and prevent a future exposure from occurring within the unnamed
intermittent stream.
Page 7 of 22 PCN Form Version 4.3-April 20,2022

4i. Describe the overall project in detail, including the type of equipment to be used:
The maintenance location will be accessed through CPC's existing, mowed, and maintained ROW from NC-751.
Temporary prefabricated mats will be used to cross emergent wetland areas W1 and W2 within CPC's ROW to
access the maintenance location and operate equipment (Figure 3; Appendix B). Based on our discussions with
CPC's maintenance inspector, it is our understanding that CPC intends to inspect Line 24 and replace the
required minimal protective cover over the pipeline using Submar revetment mats and riprap to remediate the
streambank erosion associated with the pipeline exposure (Appendix A). To re-establish the required pipeline
protective cover, CPC intends to conduct the following: 1) excavate Line 24; 2) inspect and make repairs to Line
24, as necessary; 3) grade the site for mat installation; 4) install riprap above and below the revetment mats,
which will be "keyed" into the streambed/banks and abutting wetland in a manner that will re-establish pre-
erosional contours and elevations of the streambed, providing the required pipeline cover and maintain existing
flow conditions; and 5) re-seed with native wetland seed mix and straw the surrounding disturbed area (Appendix
A).
To minimize sedimentation to the unnamed intermittent stream during the above-mentioned maintenance activity,
dams constructed of sandbags, steel plates, or water-inflatable plastic dams will be temporarily placed upstream
of the maintenance area to conduct maintenance activities "in-the-dry". The stream flow will be pumped around
the maintenance area, discharging immediately downstream via an energy dissipater to prevent stream scour.
The pump(s) used will be sufficiently sized to accommodate the anticipated stream flow (Appendix C). The
excavated ordered soils will be temporarily stored on geotextile (or similar) material in the adjacent upland area
within CPC's ROW.
Rip rap will be placed on an erosion control blanket (geotextile fabric) to stabilize the revetment mats in a manner
where the finished top elevation of the riprap does not exceed that of the streambed elevation. Once the required
minimal protective pipeline cover(pre-cast revetment mats) is keyed into the streambed/banks in a manner that
maintains existing grade, low and normal flow conditions of the stream, the temporary dams will be removed, and
normal streamflow will be restored (Appendix A).
We understand CPC's standard erosion control practices will be employed (Appendix D). Specifically, as stated
above the disturbed areas along the stream banks and emergent wetland will be reseeded with native wetland
seed mix and straw to stabilize the recently disturbed soils.
Equipment will include: an excavator, rock truck (for material transport), properly sized pumps, temporary access
mats, and a welding truck (to conduct pipe repairs as necessary).
4j. Attach project drawings/site diagrams/depictions of impact areas for the proposed project.

5j. What data sources did you use to determine whether your site would impact Endangered Species or Designated
Critical Habitat? *
A habitat assessment was completed for the three (3) species listed on the IPaC official species list:
1. Atlantic pigtoe (Fusconaia masoni). The Atlantic pigtoe (Threatened) occupies mostly medium to large streams
with clean, swift waters and stable gravel or sand substrate.
2. Red-cockaded woodpecker(Picoides borealis). The red-cockaded woodpecker(Endangered) is found in
excavated roost and nest cavities within living pine trees. Longleaf pine is the preferred habitat of red-cockaded
woodpecker, however they will also utilize loblolly, shortleaf, slash, and pond pine.
3. Harperella (Ptilimnium nodosum). Harperella (Endangered) is typically found in rocky or gravelly shoals of fast-
moving, clear streams, or on the edges of pineland ponds or damp meadows in the coastal plain.
The maintenance activities will be conducted within CPC's mowed and maintained ROW. Two emergent wetland
areas and one intermittent stream were observed and do not provide suitable habitats (terrestrial/aquatic) for the
above-mentioned species. Additionally, the above-mentioned species were not observed within the project site;
therefore, we believe the project will have "no effect" on protected species. Please see the attached IPaC.

Project Code: 2022-0027307
Project Name: CPC SE Line 24 Exposure, Chatham Co., NC
Subject: List of threatened and endangered species that may occur in your proposed project
location or may be affected by your proposed project
To Whom It May Concern:
The enclosed 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. The species list fulfills the
requirements of the U.S. Fish and Wildlife Service (Service) under section 7(c) of the
Endangered Species Act(Act) of 1973, as amended (16 U.S.C. 1531 et seq.).
New information based on updated surveys, changes in the abundance and distribution of
species, changed habitat conditions, or other factors could change this list. Please feel free to
contact us if you need more current information or assistance regarding the potential impacts to
federally proposed, listed, and candidate species and federally designated and proposed critical
habitat. Please note that under 50 CFR 402.12(e) of the regulations implementing section 7 of the
Act, the accuracy of this species list 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 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.
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

04/01/2022 2
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.
If a Federal agency 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
Migratory Birds: In addition to responsibilities to protect threatened and endangered species
under the Endangered Species Act(ESA), there are additional responsibilities under the
Migratory Bird Treaty Act(MBTA) and the Bald and Golden Eagle Protection Act(BGEPA) to
protect native birds from project-related impacts.Any activity, intentional or unintentional,
resulting in take of migratory birds, including eagles, is prohibited unless otherwise permitted by
the U.S. Fish and Wildlife Service (50 C.F.R. Sec. 10.12 and 16 U.S.C. Sec. 668(a)). For more
information regarding these Acts see https://www.fws.gov/birds/policies-and-regulations.php.
The MBTA has no provision for allowing take of migratory birds that may be unintentionally
killed or injured by otherwise lawful activities. It is the responsibility of the project proponent to
comply with these Acts by identifying potential impacts to migratory birds and eagles within
applicable NEPA documents (when there is a federal nexus) or a Bird/Eagle Conservation Plan
(when there is no federal nexus). Proponents should implement conservation measures to avoid
or minimize the production of project-related stressors or minimize the exposure of birds and
their resources to the project-related stressors. For more information on avian stressors and
recommended conservation measures see https://www.fws.gov/birds/bird-enthusiasts/threats-to-
birds.php.
In addition to MBTA and BGEPA, Executive Order 13186: Responsibilities of Federal Agencies
to Protect Migratory Birds, obligates all Federal agencies that engage in or authorize activities
that might affect migratory birds, to minimize those effects and encourage conservation measures
that will improve bird populations. Executive Order 13186 provides for the protection of both
migratory birds and migratory bird habitat. For information regarding the implementation of
Executive Order 13186, please visit https://www.fws.gov/birds/policies-and-regulations/
executive-orders/e0-13186.php.
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 Code 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 4 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
Fisheriesl, 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
