SUBJECT: Scoping for R-3101: Upgrade US 21 to a twenty-foot, two-lane facility with two foot paved
shoulders, from SR 1100 in Raoring Gap to SR 1121 in Sparta, Alleghany County, WBS 37044. 1.1
In reply to your correspondence dated August 2, 2005 in which you requested comments for the above referenced project,
the NC Division of Water Quality offers the following comments:
Preliminary analysis of the project reveals the potential for multiple impacts to streams and/or jurisdictional wetlands in
the project area. More specifically, possible impacts to main stern and tributaries to the following streams:

Further investigations at a higher resolution should be undertaken to verify the presence of all 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. Future documents should provide a detailed and itemized presentation of the proposed impacts to wetlands and
streams with corresponding mapping.
B. 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.
C. 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.
D. 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. yO?e,iCar° Ina

13. If foundation test borings are necessary; it should be noted in the document. Gcotechnical work is approved under
General 401 Certification Number 3027/Nationwide Permit No. 6 for Survey Activities.
In accordance with the Environmental Management Commission's 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 (I 5A NCAC 2H.0506 (h)(3)), the Wetland Restoration
Program may be available for use as stream mitigation.
C,. Sediment and erosion control measures should not be placed in wetlands.
li. While the use of National Wetland Inventory (NWI) Wraps and soil surveys is a useful office tool, their inherent
inaccuracies require that qualified personnel perform onsite wetland delineations prior to permit approval.
1. An analysis of cumulative and secondary impacts anticipated as a result of this project is required.
1. Environmental assessment alternatives should consider design criteria that reduce the impacts to streams and
wetlands from storm water runoff. These alternatives. should include road designs that allow for treatment of the
storm water runoff through best management practices as detailed in Best Management Practices for the Protection
of Surface Waters, such as grassed swales, buffer areas, preformed scour holes, retention basins, etc.
K. When practical, the DWQ requests that bridges be replaced on the existing location Nvith road closure. If a detour
proves necessary, remediation measures in accordance with the NCDWQ requirements for General 401
Certification. No. 3366/Nationwide Permit No. 33 (Temporary Construction, Access and Dewatering) must be
followed.
L. Where streams must be crossed, the DWQ prefers bridges be used in lieu of culverts. However, we realize that
economic considerations often require the use of culverts. Please be advised that culverts should be countersunk to
allow unimpeded passage by fish and other aquatic organisms. Moreover, in areas where high quality wetlands or
streams are impacted, a bridge may prove preferable. When applicable, DOT should not install the bridge bents in
the creek, to the maximum extent practicable.
Thank you for requesting our input at this time. The DOT is reminded that issuance of a 401 Water Quality Certification
requires that appropriate treasures 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 Sue Homewood at 336-771-

In reply to the request for comments on the referenced project, preliminary analysis of the project indicates that
the following water resources in Hydrologic Unit 05-07-03 would be impacted:
Stream Name River Basin Stream Classification Stream Index Number
Laurel Branch New River C; Tr 10-9-10-2
Brush Creek New River C; Tr 10-9-10
Little Glade Creek New River C; Tr 10-9-10-3
Glade Creek New River Q Tr 10-9-9
Any impacts to these streams, unnamed tributaries to these streams, wetlands, or open water bodies associated
with the referenced project would require a 401 Water Quality Certification from the NC Division of Water
Quality (DWQ). DWQ has the following comments regarding the development of the environmental assessment
for the referenced project:
Project Specific Comments
• The named streams in the project area are classified as Class C; Trout waters of the State. DWQ is very
concerned with sedimentation and erosion that could result from this project. The proposed environmental
assessment should address these concerns by describing the potential impacts that may occur to the aquatic
environments and any mitigating factors that would reduce the impacts.
The environmental document should provide a detailed and itemized presentation of the proposed impacts to
wetlands and streams with corresponding mapping. If mitigation is necessary as required by 15A NCAC
211.0506(b)(6), it is preferable to present a conceptual (if not finalized) mitigation plan with the environmental
documentation. Appropriate mitigation plans will be required prior to issuance of a 401 Water Quality
Certification.
Environmental assessment alternatives should consider design criteria that reduce the impacts to streams and
wetlands from storm water runoff. These alternatives should include road designs that allow for treatment of
the storm water runoff through best management practices as detailed in Best Management Practices for the
Protection of Surface Waters, such as grassed swales, buffer areas, preformed scour holes, retention basins,
etc.
General Comments
• . 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 No. 3366/Nationwide Permit No. 33 (Temporary Construction, Access and Dewatering)
must be followed.

• After the selection of the preferred alternative and prior to an issuance of the 401 Water Quality
Certification, the NCDOT is respectfully reminded that they will need to demonstrate the avoidance and
minimization of impacts to wetlands and streams to the maximum extent practical.
In accordance with the Environmental Management Commission's Rules 115A NCAC 211.0506(b)(6) 1,
mitigation will be required for impacts of greater than 150 linear feet to any single. perennial stream and for
impacts of greater than 1 acre to any wetlands. In the event that mitigation is required, the mitigation plan
should be designed to replace appropriate lost functions and values. In accordance with the Environmental
Management Commission's Rules 115A NCAC 2H.0506 (h)(3) 1, the NC Ecosystem Enhancement
Program may be available for use as stream mitigation.
• DWQ prefers replacement of bridges with bridges.
• Any new culverts must be countersunk to allow unimpeded fish and other aquatic organisms passage
through the crossing.
• 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.
• Sediment and erosion control measures should not be placed in wetlands.
• Borrow/waste areas should avoid wetlands to the maximum extent practicable. Impacts to wetlands in
borrow/waste areas could precipitate compensatory mitigation.
• The 401 Water Quality Certification application will need to specifically address the proposed methods for
storm water management. More specifically, storm water will not be permitted to discharge directly into
the creek. Instead, storm water should be designed to drain to a properly designed storm water detention
facility/apparatus.
• 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

5) North Carolina Department of Environmental and Natural Resources (NCDENR)
The National Heritage Program has identified several rare species within the proposed
project area. The species are as follows:
Species Status
Bog Turtle (Glyptemys muhlenbergii) State Threatened and Federal Threatened Due
to Similarity of Appearance
Grayson crayfish ostracod (Ascetocythere
cosmeta) Significantly Rare and Federal Species of
Concern
Cranberry (Vaccinium macrocar on) Significantly Rare
Bo featherbells (Stenanthium robustum) Significantly Rare
Mitigation for impacts to wetlands, bogs or wet meadow may be required.
The Division of Parks and Recreation considers a Mountain Bog Cluster as a potential State
Park unit. A bog cluster is centered in Alleghany County and could potentially include the
Registered Natural Heritage Area and sites for the bog turtle and Gray's lily. Therefore, the
Division of Parks and Recreation desires to maintain the bog/wet meadows in its current
undisturbed condition.
The Natural Heritage Program requests that a survey for rare species and natural communities
(bogs) be conducted. The survey should focus on the bog turtle and Gray's lily populations,
and their habitats.
6) Tennessee Valley Authority (TVA)
There will be no TVA involvement with this project.
