To: William D. Gilmore, P.E., Manager, NCDOT, Project Development & Environmental Analysis
From: John E. Hennessy, NC Division of Water Quality
Subject: Scoping comments on proposed construction of a flyover interchange at the intersection of US
158 and NC 168, in Currituck County, Federal Aid Project No. NIF-158, State Project No.
8.104090 1, TIP R-401 1.
Reference your correspondence dated July 8, 1999 in which you requested comments for the proposed
construction of a flyover interchange at the intersection of US 158 and NC 168 (TIP R-4011). Preliminary
analysis of the project reveals the potential for multiple impacts to perennial streams and jurisdictional
wetlands in the project area. Further investigations at a higher resolution should be undertaken to verify the
presence of other streams and/or jurisdictional wetlands in the area. In the event that any jurisdictional
areas are identified, the Division of Water Quality requests that NCDOT consider the following
environmental issues for the proposed project:
A. We would like to see a discussion in the document that presents a sufficient purpose and need to
justify the project's existence. Based on the information presented in your report, we assume that
the Level-of- Service (LOS) is one of the primary reasons for the project. Therefore, the document
should delineate a detailed discussion on the existing Level-of-Service as well as the proposed future
Level-of-Service. The discussion for the future Level-of-Service should consider the Level-of-
Service with and without the project.
B. The document should provide a detailed and itemized presentation of the proposed impacts to
wetlands and streams with corresponding mapping.
C. There should be a discussion on mitigation plans for unavoidable impacts. If mitigation is required,
it is preferable to present a conceptual (if not finalized) mitigation plan with the environmental
documentation. While the NCDWQ realizes that this may not always be practical, it should be noted
that for projects requiring mitigation, appropriate mitigation plans will be required prior to issuance
of a 401 Water Quality Certification.
D. Review of the project reveals that no Outstanding Resource Waters, Water Supply Water, High
Quality Waters, Body Contact Waters, or Trout Waters will be impacted during the project
implementation. However, should further analysis reveal the presence of any of the aforementioned
waters, the DWQ requests that DOT strictly adhere to North Carolina regulations entitled "Design
Standards in Sensitive Watersheds" (15A NCAC 04B .0024) throughout design and construction of
the project. This would apply for any area that drains to streams having WS (Water Supply), ORW
(Outstanding Resource Water), HQW (High Quality Water), B (Bodv Contact), SA (Shellfish
Water) or Tr (Trout Water) classifications.

Patze 2
E. When practical, the DWQ requests that bridges be replaced on the existing location with road
closure. If a detour proves necessary, remediation measures in accordance with the NCDWQ
requirements for General 401 Certification 2726/Nationwide Permit No. 33 (Temporary
Construction, Access and Dewatering) must be followed.
F. Review of the project reveals that no High Quality Waters or Water Supply Waters will be impacted
by the project. However, should further analysis reveal the presence of any of the aforementioned
water resources, the DWQ requests that hazardous spill catch basins be installed at any bridge
crossing a stream classified as HQW or WS (Water Supply). The number of catch basins installed
should be determined by the design of the bridge, so that runoff would enter said basin(s) rather than
flowing directly into the stream.
G. If applicable, DOT should not install the bridge bents in the creek, to the maximum extent
practicable.
H. Wetland and stream impacts should be avoided (including sediment and erosion control
structures/measures) to the maximum extent practical. If this is not possible, alternatives that -
minimize wetland impacts should be chosen. Mitigation for unavoidable impacts will be required by
DWQ for impacts to wetlands in excess of one acre and/or to streams in excess of 150 linear feet.
1. Borrow/waste areas should not be located in wetlands. It is likely that compensatory mitigation will
be required if wetlands are impacted by waste or borrow.
G. DWQ prefers replacement of bridges with bridges. However, if the new structure is to be a culvert, it
should be countersunk to allow unimpeded fish and other aquatic organisms passage through the
crossing.
H. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is
approved under General 401 Certification Number 3027/Nationwide Permit No. 6 for Survey
Activities.
In accordance with the NCDWQ Wetlands Rules { 15A NCAC 21-1.0506(b)(6)), mitigation will be
required for impacts of greater than 150 linear feet to any single perennial stream. In the event that
mitigation becomes required, the mitigation plan should be designed to replace appropriate lost
functions and values. In accordance with the NCDWQ Wetlands Rules { 15A NCAC 2H.0506
(h)(3)), the Wetland Restoration Program may be available for use as stream mitigation.
Sediment and erosion control measures should not be placed in wetlands.
K. The 401 Water Quality Certification application will need to specifically address the proposed
methods for stormwater management. More specifically, stormwater should not be permitted to
discharge directly into the creek. Instead, stormwater should be designed to drain to a properly
designed stormwater detention facility/apparatus.
L. While the use of National Wetland Inventory (NWI) maps and soil surveys is a useful office tool,
their inherent inaccuracies require that qualified personnel perform onsite wetland delineations prior
to permit approval.

8.1040901, F. A. Project NHF-158(10), T.I.P. Project R-4011
The Project Development and Environmental Analysis Branch of the Division of
Highways has begun studying the proposed project to construct a trumpet interchange at the
at-grade intersection of US 158 and NC 168. The project is included in the 2000-2006 North
Carolina Transportation Improvement Program and is scheduled for right of way in fiscal year
2001 and construction in fiscal year 2002.
The project calls for a trumpet interchange to be constructed at the intersection of US 158
and NC 168 to alleviate traffic congestion during peak summer weekends and during adverse
weather evacuations of the Outer Banks and surrounding areas. A ramp will be added to the
northbound approach of US 158 for traffic traveling west on US 158 towards Elizabeth City. A
loop for the eastbound approach of US 158 will be for traffic wishing to travel north toward
Virginia on NC 168. A right turn lane will also be constructed at the eastbound approach for
US 158 traffic traveling to the coastal areas. The southbound approach (NC 168) will have a
right turn lane for traffic wishing to travel west on US 158 toward Elizabeth City. There will be
no traffic signals and the interchange right of way will be fully controlled.
We would appreciate any information you might have that would be helpful in evaluating
potential environmental impacts of the project. If applicable, please identify any permits or
approvals which may be required by your agency. Your comments will be used in the
preparation of a federally funded Environmental Assessment. This document will be prepared in
accordance with the National Environmental Policy Act. It is desirable that your agency respond
by November 30, 1999 so that your comments can be used in the preparation of this document.

Dear Mr. Gilmore:
i
Thank you for your letter of August 31, 1999, requesting information from the U.S. Fish and
Wildlife Service (Service) for the purpose of evaluating the potential environmental impacts of
the proposed construction of a trumpet interchange at the at-grade intersection of US 158 and NC
168, Barco, Currituck County, North Carolina (TIP No. R-4011). This report provides scoping
information and is provided in accordance with provisions of the Fish and Wildlife Coordination
Act (FWCA) (16 U.S.C. 661-667d) and Section 7 of the Endangered Species Act (ESA) of 1973,
as amended (16 U.S.C. 1531-1543). This report also serves as initial scoping comments to
federal and state resource agencies for use in their permitting and/or certification processes for
this project.
The North Carolina Department of Transportation (NCDOT) proposes a trumpet interchange to
alleviate traffic congestion during peak summer weekends and during adverse weather
evacuations of the Outer Banks and surrounding areas. A ramp will be added to the northbound
approach of US 158 for traffic traveling west on US 158 towards Elizabeth City. A loop for the
eastbound approach of US 158 will be for traffic traveling north toward Virginia on NC 168. A
right turn lane will also be constructed at the eastbound approach for US 158 traffic traveling to
the coastal areas. The southbound approach (NC 168) will have a right turn lane for traffic
wishing to travel west on US 158 to Elizabeth City. There will be no traffic signals and the
interchange right of way will be fully controlled.
The mission of the Service is to provide leadership in the conservation, protection, and
enhancement of fish and wildlife, and their habitats, for the continuing benefit of all people. Due
to staffing limitations, we are unable to provide you with site-specific comments at this time.
However, the following recommendations are provided to assist you in your planning process
and to facilitate a thorough and timely review of the project.
Generally, the Service recommends that wetland impacts be avoided and minimized to the
maximum extent practical as outlined in Section 404 (b)(1) of the Clean Water Act Amendments
of 1977. In regard to avoidance and minimization of impacts, we recommend that proposed
highway projects be aligned along or adjacent to existing roadways, utility corridors, or
previously developed areas in order to minimize habitat fragmentation and encroachment. Areas
exhibiting high biodiversity or ecological value important to the watershed and region should be
avoided. Crossings of streams and associated wetland systems should use existing crossings
and/or occur on a structure wherever feasible. Where bridging is not feasible, culvert structures
that maintain natural water flows and hydraulic regimes without scouring, or impeding fish and
wildlife passage, should be employed. Highway shoulder and median widths should be reduced
through wetland areas. Roadway embankments and fill areas should be stabilized by using
appropriate erosion control devices and techniques. Wherever appropriate, construction in
sensitive areas should occur outside fish spawning and migratory bird nesting seasons.
The National Wetlands Inventory (NWI) map of the Barco 7.5 Minute Quadrangle does not show
any wetland resources at the project site. However, while the NWI maps are useful for providing
an overview of a given area, they should not be relied upon in lieu of a detailed wetland
delineation by trained personnel using an acceptable wetland classification methodology.
We reserve the right to review any federal permits that may be required for this project, at the
public notice stage. We may have no objection, provide recommendations for modification of
the project, or recommend denial. Therefore, it is important that resource agency coordination
occur early in the planning process in order to resolve any conflicts that may arise and minimize
delays in project implementation.
In addition to the above guidance, we recommend that the environmental documentation for this
project include the following in sufficient detail to facilitate a thorough review of the action:
1. A clearly defined purpose and need for the proposed project, including a discussion of the
project's independent utility;
A description of the proposed action with an analysis of all alternatives being considered,
including the upgrading of existing roads and a "no action" alternative;
A description of the fish and wildlife resources, and their habitats, within the project
impact area that may be directly or indirectly affected;
4. The extent and acreage of waters of the U.S., including wetlands, that are to be impacted
by filling, dredging, clearing, ditching, or draining. Acres of wetland impact should
be differentiated by habitat type based on the wetland classification scheme of the
National Wetlands Inventory (NWI). Wetland boundaries should be determined by using
the 1987 Corps of Engineers Wetlands Delineation Manual and verified by the U.S.
Army Corps of Engineers (Corps);
The anticipated environmental impacts, both temporary and permanent, that would be
likely to occur as a direct result of the proposed project. The assessment should also
include the extent to which the proposed project would result in secondary impacts to
natural resources, and how this and similar projects contribute to cumulative adverse
effects;
6. Design features and construction techniques which would be employed to avoid or
minimize the fragmentation or direct loss of wildlife habitat value;
7. Design features, construction techniques, or any other mitigation measures which
would be employed at wetland crossings and stream channel relocations to avoid or
minimize impacts to waters of the United States; and,
8. If unavoidable wetland impacts are proposed, we recommend that every effort be made to
identify compensatory mitigation sites in advance. Project planning should include a
detailed compensatory mitigation plan for offsetting unavoidable wetland impacts.
Opportunities to protect mitigation areas in perpetuity, preferably via conservation
easement, should be explored at the outset.
The attached page identifies the federally-listed endangered, threatened, and Federal Species of
Concern (FSC) that are known to occur in Currituck County. Habitat requirements for the
federally-listed species in the project area should be compared with the available habitat at the
project site. If suitable habitat is present within the action area of the project, field surveys for
the listed species should be performed. Environmental documentation should include survey
methodologies and results. In addition to this guidance, the following information should be
included in the document regarding protected species:
A map and description of the specific area used in the analysis of direct, indirect, and
cumulative impacts;
2. A description of the biology and status of the listed species and the habitat of the species
that may be affected by the action, including the results of any onsite inspections;
An analysis of the "effects of the action" on the listed species and associated habitat
which includes consideration of:
a. The environmental baseline which is an analysis of the effects of past and ongoing
human and natural factors leading to the current status of the species and its
habitat;
b. The impacts of past and present federal, state, and private activities in the project
area and cumulative impacts area;
The direct and indirect impacts of the proposed action. Indirect effects are those
that are caused by the proposed action and are later in time, but are still
reasonably certain to occur;
d. The impacts of interrelated actions (those that are part of a larger action and
depend on the larger action for their justification) and interdependent actions
(those that have no independent utility apart from the action under consideration);
and,
The cumulative impacts of future state and private activities (not requiring federal
agency involvement) that will be considered as part of future Section 7
consultation.
4. A description of the manner in which the action may affect any listed species or
associated habitat including project proposals to reduce/eliminate adverse effects. Direct
mortality, injury, harassment, the loss of habitat, and/or the degradation of habitat are all
ways in which listed species may be adversely affected;
5. A summary of evaluation criteria to be used as a measure of potential effects. Criteria
may include post-project population size, long-term population viability, habitat quality,
and/or habitat quantity; and,
6. Based on evaluation criteria, a determination of whether the project is not likely to
adversely affect or may affect threatened and endangered species.
FSC's include those plant and animal species for which the Service remains concerned, but
further biological research and field study are needed to resolve the conservation status of these
taxa. Although FSC's receive no statutory protection under the ESA, we would encourage the
NCDOT to be alert to their potential presence, and to make every reasonable effort to conserve
them if found. The North Carolina Natural Heritage Program should be contacted for information
on species under state protection.
The Service appreciates the opportunity to comment on this project. Please continue to advise us
during the progression of the planning process, including your official determination of the
impacts of this project. If you have any questions regarding these comments, please contact
Mr. Tom McCartney at 919-856-4520, ext. 32.

requirements for General 401 Certification 2726/Nationwide Permit No. 33 (Temporary
Construction, Access and Dewatering) must be followed.
F. Review of the project reveals that no High Quality Waters or Water Supply Waters will be impacted
by the project. However, should further analysis reveal the presence of any of the aforementioned
water resources, the DWQ requests that hazardous spill catch basins be installed at any bridge
crossing a stream classified as HQW or WS (Water Supply). The number of catch basins installed
should be determined by the design of the bridge, so that runoff would enter said basin(s) rather than
flowing directly into the stream.
G. If applicable, DOT should not install the bridge bents in the creek, to the maximum extent
practicable.
H. Wetland and stream impacts should be avoided (including sediment and erosion control
structures/measures) to the maximum extent practical. If this is not possible, alternatives that
minimize wetland impacts should be chosen. Mitigation for unavoidable impacts will be required by
DWQ for impacts to wetlands in excess of one acre and/or to streams in excess of 150 linear feet.
1. Borrow/waste areas should not be located in wetlands. It is likely that compensatory mitigation will
be required if wetlands are impacted by waste or borrow.
G. DWQ prefers replacement of bridges with bridges. However, if the new structure is to be a culvert, it
should be countersunk to allow unimpeded fish and other aquatic organisms passage through the
crossing.
H. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is
approved under General 401 Certification Number 3027/Nationwide Permit No. 6 for Survey
Activities.
1. In accordance with the NCDWQ Wetlands Rules { 15A NCAC 2H.0506(b)(6) }, mitigation will be
required for impacts of greater than 150 linear feet to any single perennial stream. In the event that
mitigation becomes required, the mitigation plan should be designed to replace appropriate lost
functions and values. In accordance with the NCDWQ Wetlands Rules (15A NCAC 2H.0506
(h)(3) }, the Wetland Restoration Program may be available for use as stream mitigation.
J. Sediment and erosion control measures should not be placed in wetlands.
K. The 401 Water Quality Certification application will need to specifically address the proposed
methods for stormwater management. More specifically, stormwater should not be permitted to
discharge directly into the creek. Instead, stormwater should be designed to drain to a properly
designed stormwater detention facility/apparatus.
L. While the use of National Wetland Inventory (NWI) maps and soil surveys is a useful office tool,
their inherent inaccuracies require that qualified personnel perform onsite wetland delineations prior
to permit approval.

Thank you for requesting our input at this time. The DOT is reminded that issuance of a 401 Water Quality
Certification requires that appropriate measures be instituted to ensure that water quality standards are met
and designated uses are not degraded or lost. If you have any questions or require additional information,
please contact John Hennessy at [phone].

FROM: William D. Gilmore, P. E '&ager
Project Development and Environmental Analysis Branch
SUBJECT: Barco, US 158 at NC 168, Currituck County, State Project
8.1040901, F. A. Project NHF-158(10), T.I.P. Project R-4011
The Project Development and Environmental Analysis Branch of the Division of
Highways has begun studying the proposed project to construct a trumpet interchange at the
at-grade intersection of US 158 and NC 168. The project is included in the 2000-2006 North
Carolina Transportation Improvement Program and is scheduled for right of way in fiscal year
2001 and construction in fiscal year 2002.
The project calls for a trumpet interchange to be constructed at the intersection of US 158
and NC 168 to alleviate traffic congestion during peak summer weekends and during adverse
weather evacuations of the Outer Banks and surrounding areas. A ramp will be added to the
northbound approach of US 158 for traffic traveling west on US 158 towards Elizabeth City. A
loop for the eastbound approach of US 158 will be for traffic wishing to travel north toward
Virginia on NC 168. A right turn lane will also be constructed at the eastbound approach for
US 158 traffic traveling to the coastal areas. The southbound approach (NC 168) will have a
right turn lane for traffic wishing to travel west on US 158 toward Elizabeth City. There will be
no traffic signals and the interchange right of way will be fully controlled.
We would appreciate any information you might have that would be helpful in evaluating
potential environmental impacts of the project. If applicable, please identify any permits or
approvals which may be required by your agency. Your comments will be used in the
preparation of a federally funded Environmental Assessment. This document will be prepared in
accordance with the National Environmental Policy Act. It is desirable that your agency respond
by November 30, 1999 so that your comments can be used in the preparation of this document.
If you have any questions concerning the project, please contact Bill Kinlaw, Project
Development Engineer, of this Branch at [phone], Ext. 222.
