Pam, here are DWQ's comments on the Division 8 Design Build Bridge Replacement projects we reviewed in the
field on October 6th and 7th. These are in addition to those which were made in the field and documented by
you and your staff. It was noted that there are some complex issues associated with the following projects
which could not be resolved during our site visit: 620073 (proposed structure and onsite detour), 620096
(proposed design on new location), 750029 (potential new location and historic concerns), 750075 (historic
structure under bridge, potential new location, adjacent mitigation site) and 750067 (proposed design on new
location). DWQ would like to request that DOT keep us informed of any proposed resolutions to these issues.
I would personally like to thank you and all of the DOT staff who participated, for allowing DWQ to review these
projects with you and for giving us an opportunity to comment on these projects.
If I can be of any further assistance or if you have questions about the comments I provided, please do not
hesitate to contact me.

Beaver Creek, Cabin Creek and Uwharrie Creek are class WS III; 303(d) waters of the State. Beaver
Creek, Cabin Creek and Uwharrie Creek are on the 303(d) list for impaired use for aquatic life due
to biological integrity criteria. NCDWQ is very concerned with sediment and erosion impacts that
could result from this project. NCDWQ recommends that the most protective sediment and erosion
control BMPs be implemented in accordance with Design Standards in Sensitive Watersheds to
reduce the risk of nutrient runoff to Beaver Creek, Cabin Creek and Uwharrie Creek. NCDWQ
requests that road design plans provide treatment of the storm water runoff through best management
practices as detailed in the most recent version of NCDWQ Stormwater Best Management Practices.

2. Review of the project reveals the presence of surface waters classified as WS -II; High Quality
Waters of the State at Bridge 750075 over UT to Back Creek. This is one of the highest
classifications for water quality. Pursuant to 15A NCAC 2H .1006 and 15A NCAC 213 .0224,
NCDOT will be required to obtain a State Stormwater Permit prior to construction except in North
Carolina's twenty coastal counties.
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 a bridge is being replaced with a hydraulic conveyance other than another bridge, NCDWQ
believes the use of a Nationwide Permit may be required. Please contact the US Army Corp of
Engineers to determine the required permit(s).
6. If the old bridge is removed, no discharge of bridge material into surface waters is allowed unless
otherwise authorized by the US ALOE. 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.
8. 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.
9. 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.
10. 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.
11. 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.
12. 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.

13. 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.
14. 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.
15. 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.
16. Any impacts to waters of the state resulting from utility relocations associated with these bridge
replacement projects must be noted in the project document. Utility relocations are generally
authorized in accordance with the conditions of General 401 Certification Number 3819/Nationwide
Permit No. 12 for Utility Line Activities.
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 me at (910) 308 -4021.
