General Comments Regarding Bridge Replacement Protects
1 NCDWQ is very concerned with sediment and erosion impacts that could result from these projects
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
2 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
3 Any Low Impact Bridge Protects must fall under Nationwide Permit No 3 to qualify for Low Impact
otherwise standard permitting procedures will be required Example (Regional General Permit No
31 Nationwide Permit No 23 Nationwide Permit No 13 etc)
4 Whenever possible NCDWQ prefers spanning structures Spanning structures usually do not require
work within the stream or grubbing of the stream banks 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
5 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
NCDWQ's Stormwater Best Management Practices
6 Strict adherence to the most recent version of NCDOT s Best Management Practices For Bridge
Demolition and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water
Quality Certification
7 Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft
construction methods More specifically betting or other methods of pile driving are prohibited without
prior written approval from NCDWQ first
8 No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter surface
waters This water shall be captured treated and disposed of properly
9 All pile driving or drilling activities shall be enclosed in turbidity curtains unless otherwise approved by
NCDWQ in this certification
10 All bridge construction shall be performed from the existing bridge temporary work bridges
temporary causeways or floating or sunken barges If work conditions require barges they shall be
floated into position and then sunk The barges shall not be sunk and then dragged into position Under
no circumstances should barges be dragged along the bottom of the surface water
11 All work in or adjacent to stream waters shall be conducted in a dry work area 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 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
(6)

not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and
fish kills
13 Heavy equipment shall be operated from the banks rather than in the stream channel in order to
minimize sedimentation and reduce the introduction of other pollutants into the stream This equipment
shall be inspected daily and maintained to prevent contamination of surface waters from leaking fuels
lubricants hydraulic fluids or other toxic materials
14 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
15 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
16 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 the opportunity to provide comments 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 Mike Parker at 828 296 4500
