best management practices as detailed in the most recent version of NCDWR's Stormwater Best Management
Practices and NCDOT's Stormwater Best Management Practices Toolbox.
3. Review of the project reveals the presence of surface waters classified as High Quality Waters (HQW) of the
State in the project study area (Cane Creek). This is one of the highest classifications for water quality. Given
the potential for impacts ro these resources during the project implementation, the NCDWR requests that DOT
strictly adhere to North Carolina regulations entitled "Design Standazds in Sensitive Watersheds" Q SA NCAC
04B .0124) throughout design and construction of the project and that NCDOT's National Pollutant Dischazge
Elimination System (NPDES) permit NCS000250 is strictly enforced along with the requirements of
Stormwater Discharge General Permit NCGO10000 for Construction Activities.
4. Any anticipated bank stabilization associated with culvert installations or extensions should be addressed in the
Categorical Exclusion (CE) document. It is understood that final designs aze not determined at the time the CE
is developed. However, the CE should discuss the potential for bank stabilization necessary due to culvert
installation.
5. 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.
6. ff foundation test borings are necessary; it shall be noted in the document. Geotechnical work is approved
under General 401 Certification Number 3883/Nationwide Permit No. 6 for Survey Activities.
Z If a bridge is being replaced with a hydraulic comeyance other [han another bridge, the NCDWR believes the
use of a Nationwide Permit may be required. Ptease contact the USACE to determine the requ'ved permit(s).
8. If the old bridge is removed, no discharge of bridge material into surface waters is allowed unless otherwise
authorized by the USACE. Strict adherence to the USACE guidelines for bridge demolition will be a condition
of the 401 Water Quality CertificaHon.
9. Whenever possible, the NCDWR prefers spanning structures. Spanning structures usually do not require wotk
within the sheam or grubbing of the stream banks and do not require stream channel realignment. The
horizontal and vertical clearances provided by bridges allow for human and wildlife passage beneath the
structure and do not block fish passage.
10. Bridge deck drains shall not discharge directty 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 NCDWR Stormwater Best Management
Practrces and NCDOT's Stormwater Best Management Practices Toolbox.
11. IFconcrete 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 dischazged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
l2. Bridge suppor[s (bents) shall not be placed in the stream when possible.
13. If temporary access roads or detours aze constructed, the site shall be gaded to its preconstruction contours and
elevations. Disturbed azeas 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 azea 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.
I4. Sediment and erosion control measures sufficient to protect water resources must be implemented and
maintained in accordance with the most recent version of North Cazolina Sediment and Erosion Control
Planning and Design Manual along with the most recent version of NCS000250; including the requirements of
Stormwater Discharge General Permit NCGO10000 for Conshuction Activities.
15. All work in or adjacent to stream waters shall be conducted in a dry work area unless othenvise approved by the
NCDWR. 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.

16. Heavy equipment shall be operated from the bank rather than in stream channels in order to minimize
sedimentation and reduce the Iikelihood of introducing other pollutants inro sueams. This equipment shall be
inspected daily and maintained to prevent contamination of surface waters &om leaking fuels, lubricants,
hydraulic fluids, or other toxic materials.
I7. In most cases, the NCDWR prefers the replacement oFthe e�sting 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
impacu, minimize the need for clearing and to avoid destabilizing stream banks. If the struchue 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 azea shall be stabilized with
grnss and planted with native tree species. Tall fescue shall not be used in riparian azeas.
18. Placement of culverts and other structures in waters, streams, and wetlands shall be below the elevation of the
streambed by one foot for all culverts with a diameter greater than 48 inches, and 20 percent of the culvert
diameter for culveRs having a diameter less than 48 inches, to allow low flow passage of water and aquatic life.
Design and placement of culverts and other structures including temporary erosion control measures shall not
be conducted in a manner that may result in dis-equilibrium of wetlands or streambeds or bazilcs, adjacent to or
upstream and downstream of the above structures. The applicant is required to provide evidence that the
equilibrium is being maintained if requested in writing by the NCDWR. If this condition is unable ro be met
due to bedrock or other limiting features encountered during construction, please contact the NCDWR for
guidance on how to proceed and to determine whether or not a permit modification will be requ'ved.
l9. If multiple pipes or barrels are required, they shall be designed to mimic natural siteam cross section as closely
as possible including pipes or barrels at flood plain elevation andlor sills where appropriate. Widening the
stream channel shall be avoided. Stream channel widening at the inlet or ouUet end of structures typically
decreases water velocity causing sediment deposition that requ'ves increased maintenance and disrupts aquatic
life passage.
20. Riprap shall not be placed in the active thalweg channel or placed in the sheambed in a manner that precludes
aquatic life passage. Bioengineering boulders or structures shall be propedy designed, sized and installed.
T'he DOT is reminded that issuance of a 40l Water Quality Certification requires that appropriate measures be
instituted to ensure that water quality standazds aze met and designated uses are not degraded or lost. [f you have any
questions or require additional information, please contact Dave Wanucha at [phone] or at

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.
2. Review of the project reveals the presence of surface waters classified as WSII; High Quality
Waters of the State in the project study area. This is one of the highest classifcations for water
quality. Pursuant to 15A NCAC 2H .1006 and 15A NCAC 2B .0224, NCDOT will be required to
obtain a State Stormwater Permit prior to construction except in North Carolina's twenty coastal
counties.
3. This project is within the Jordan Lake Riparian buffer impacts shall be avoided and minimized to
the greatest extent possible pursuant to 15A NCAC 2B .0267.
Brid�e No. 106 (SR 1156) over Burkes Creek in Caswell County
*Potential impacts to Burkes Creek. No project specific comments.
General Project Comments:
1. For bridges that are to be replaced with single aluminum box culverts that are wider than the existing
stream, measures shall be taken to maintain the stream width at the inlet and outlet of the pipe and
maintain aquatic passage within the culvert. Please refer to the DWQs "Aluminum Box Culverts with
Bottoms" review dated February 2012.
2. For bridges that are to be replaced with bottomless culverts, channel width must be maintained within
the culvert. Keying large rock into the floodplain within the culvert is preferred.
3. For bridges that are to be replaced with multiple barrel culverts, sills and/or floodplain benches shall
be utilized at the inlet and outlet of the high flow barrel to isolate low flow to a single barrel.
4. For bridges that are to be replaced using the Low Impact Bridge replacement process, a Nationwide 3
from the US Army Corps of Engineers will be required. NCDWQ would like to respectively remind
NCDOT that WQC 3883, or its most recent equivalent, will also be required. NCDOT shall be in
compliance with all of its applicable conditions.
5: DWQ understands that bridges to be replaced through the Low Impact Bridge replacement process
will be replaced using an off-site detour. If at any time these plans change, DWQ shall be contacted
to determine if these project can remain in the Low-Impact Bridge Replacement process.
6. Environmental assessment alternatives shall consider design criteria that reduce the impacts to
streams and wetlands from storm water runoff. These alternatives shall include road designs that
allow for treatment of the storm water runoff through best management practices as detailed in the
most recent version of NCDWQ Stormwater Best Management Practices, such as grassed swales,
buffer areas, preformed scour holes, retention basins, etc.

Currently proposed impacts will not exceed 150 linear feet of impacts to any single stream. However,
if at any point in the future the impact totals change, then in accordance with the Environmental
Management Commission's Rules { 15A NCAC 2H.0506(h)}, mitigation will be required for impacts
of greater than 1501inear feet to any single stream. In the event that mitigation is required, the
mitigation plan shall be designed to replace appropriate lost functions and values. The NC Ecosystem
Enhancement Program may be available for use as stream mitigation.
8. 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.
9. 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.
10. 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) shall not be placed in the stream when possible.
1 l. 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.
� � 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
not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and
fish kills.
13. If temporary access roads or detours are constructed, the site shall be graded to its preconstruction
contours and elevations. Disturbed areas shall be seeded ar mulched to stabilize the soil and
appropriate native woody species should 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.
14. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is
approved under Genera1401 Certification Number 3624/Nationwide Permit No. 6 for Survey
Activities.
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. 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 should be used to prevent excavation in flowing water.

17. Sediment and erosion control measures shall not be placed in wetlands and streams.
18. Borrow/waste areas shall avoid wetlands to the maximum extent practical. Impacts to wetlands in
borrow/waste areas could precipitate compensatory mitigation. .
19. 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.
20. Riprap shall not be placed in the active thalweg channel or placed in the streambed in a manner that
precludes aquatic life passage. Bioengineering boulders or structures should be properly designed,
sized and installed.
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 Amy Euliss at [phone].
