MEMORANDUM
TO: Tracy A. Walter, NCDOT
FROM: David Wainwright, NCDWQ'PV)
SUBJECT: Scoping Review of NCDOT's Proposed Bridge Replacement Project B- 4916, Bridge
No. 57 on US 13 over Quiccosion Swamp in Berrie County
In reply to your correspondence dated June 2, 2009 (received June 3, 2009) in which you requested
comments for the above referenced projects, the NCDWQ offers the following comments:
Project-Specific Comments
Dee Freeman
Secretary
Quioccosion Swamp (DWQ Stream Index No. 25-14-1-6-2) is class C; NSW waters of the State.
NCDWQ is very concerned with sediment and erosion impacts that could result from this project.
NCDWQ recommends that highly protective sediment and erosion control BMPs be implemented
to reduce the risk of nutrient runoff to Quioccosion Swamp. NCDWQ requests that road and
bridge design plans provide treatment of the storm water runoff through best management
practices as detailed in the most recent version of NCDWQ's Stormwater Best Management
Practices.
Any anticipated dewatering or access structures necessary for construction of bridges should be
addressed in the CE. It is understood that final designs are not determined at the time the CE is
developed. However, the CE should discuss the potential for dewatering and access measures
necessary due to bridge construction.
General Comments Regarding Bridge Replacement Projects
3. NCDWQ is very concerned with sediment and erosion impacts that could result from this project.
NCDOT shall address these concerns by describing the potential impacts that may occur to the
aquatic environments and any mitigating factors that would reduce the impacts.
4. If foundation test borings are necessary; it shall be noted in the document. Geotechnical work is
approved under General 401 Certification Number 3687/Nationwide Permit No. 6 for Survey
Activities.
If the old bridge is removed, no discharge of bridge material into surface waters is allowed unless
otherwise authorized by the US ACOE. Strict adherence to the Corps of Engineers guidelines for
bridge demolition will be a condition of the 401 Water Quality Certification.
Whenever possible, NCDWQ prefers spanning structures. Spanning structures usually do not
require work within the stream or grubbing of the streambanks and do not require stream channel

realignment. The horizontal and vertical clearances provided by bridges shall allow for human
and wildlife passage beneath the structure. Fish passage and navigation by canoeists and boaters
shall not be blocked. Bridge supports (bents) should not be placed in the stream when possible.
Bridge deck drains shall not discharge directly into the stream. Stormwater shall be directed
across the bridge and pre-treated through site-appropriate means (grassed swales, pre-formed
scour holes, vegetated buffers, etc.) before entering the stream. Please refer to the most current
version of NCD WQ's Stormwater Best Management Practices.
If concrete is used during construction, a dry work area shall be maintained to prevent direct
contact between curing concrete and stream water. Water that inadvertently contacts uncured
concrete shall not be discharged to surface waters due to the potential for elevated pH and
possible aquatic life and fish kills.
9. If temporary access roads or detours are constructed, the site shall be graded to its preconstruction
contours and elevations. Disturbed areas shall be seeded or mulched to stabilize the soil and
appropriate native woody species shall be planted. When using temporary structures the area
shall be cleared but not grubbed. Clearing the area with chain saws, mowers, bush-hogs, or other
mechanized equipment and leaving the stumps and root mat intact allows the area to re-vegetate
naturally and minimizes soil disturbance.
10. Sediment and erosion control measures sufficient to protect water resources must be implemented
and maintained in accordance with the most recent version of North Carolina Sediment and
Erosion Control Planning and Design Manual and the most recent version of NCS000250.
11. All work in or adjacent to stream waters shall be conducted in a dry work area unless otherwise
approved by NCDWQ. Approved BMP measures from the most current version of NCDOT
Construction and Maintenance Activities manual such as sandbags, rock berms, cofferdams and
other diversion structures shall be used to prevent excavation in flowing water.
12. Heavy equipment shall be operated from the bank rather than in stream channels in order to
minimize sedimentation and reduce the likelihood of introducing other pollutants into streams.
This equipment shall be inspected daily and maintained to prevent contamination of surface
waters from leaking fuels, lubricants, hydraulic fluids, or other toxic materials.
13. In most cases, the NCDWQ prefers the replacement of the existing structure at the same location
with road closure. If road closure.is not feasible, a temporary detour shall be designed and
located to avoid wetland impacts, minimize the need for. clearing and to avoid destabilizing
stream banks. If the structure will be on a new alignment, the old structure shall be removed and
the approach fills removed from the 100-year floodplain. Approach fills shall be removed and
restored to the natural ground elevation. The area shall be stabilized with grass and planted with
native tree species. Tall fescue shall not be used in riparian areas.
Thank you for requesting our input at this time. NCDOT 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 David Wainwright at [phone].

Dear John Hennessy:
SUBJECT: TIP Project No. B-4916 - Replacement of Bridge No. 57 on US 13
over Quioccosion Swamp in Bertie County. The Project Development and Environmental Analysis Branch is starting the project
development, environmental and engineering studies for the replacement of Bridge No. 57 in
Bertie County. This project is included in the North Carolina Transportation Improvement
Program and is scheduled for construction in fiscal year 2015.
We would appreciate any information you might have that would be helpful in evaluating
potential environmental impacts of the project including recommendation of alternates to be
studied. Your comments will be used in the preparation of a federally funded Categorical
Exclusion, prepared in accordance with the National Environmental Policy Act. It is desirable
that your agency respond by September 11, 2009 so that your comments can be used in the
selection of alternatives to be studied for this project.
If you have any questions concerning this project, please contact Tracy Walter at [phone].
Please include the TIP Project Number in all correspondence and comments.
Sincerely,
Tracy A. Walter
Bridge Project Planning Engineer
