Subject: Request for Comments for the Replacement of NC 226 South Smith Bridge over Young's
Fork Creek in McDowell County, State Clearinghouse No. 06-0120
In reply to your correspondence dated October 18, 2005 (received October 19, 2005) in which you
requested comments for the referenced project, the NC Division of Water Quality has the following
comments:
Project Specific Comments:
1. Any temporary or permanent impacts that would be associated with this project could potentially
require a 404 permit and a 401 Water Quality Certification. The Army Corps of Engineers will make
the determination for the type of permit required. DWQ would issue a corresponding 401 Water
Quality Certification for the impacts based on a complete and accurate application.
2. Young's Fork Creek are Class C; Tr waters of the State. DWQ recommends that the most protective
sedimentation and erosion control BMPs be implemented to reduce the risk of turbidity violations in
trout waters. In addition, all disturbances within trout buffers should be conducted in accordance with
NC Division of Land Resource and NC Wildlife Resources Commission requirements.
General Comments:
1. If the bridge will be replaced on a new location, once the existing bridge is removed the area should
be returned to the natural elevation and contours of the adjacent undisturbed areas. Native woody
vegetation should be planted in all disturbed areas. The native vegetation should be representative of
the surrounding undisturbed areas.
2. If the old bridge is removed, no discharge of bridge material into surface waters is preferred. Strict
adherence the Corps of Engineers guidelines for bridge demolition will be a condition of the 401
Water Quality Certification.
3. DWQ prefers spanning structures. Spanning structures usually do not require work within the, stream
and do not require stream channel realignment. The horizontal and vertical clearances provided by
bridges allows for human and wildlife passage beneath the structure, does not block fish passage, and
does not block navigation by canoeists and boaters.
4. Bridge deck drains should not discharge directly into the stream; stormwater should 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 NCDOT Best Management
Practices for the Protection of Surface Waters One

5. Live concrete should not be allowed to contact the water in or entering into the stream. Concrete is
mostly made up of lime (calcium carbonate) and when in a dry or wet state (not hardened) calcium
carbonate is very soluble in water and has a pH of approximately 12. In an unhardened state concrete
or cement will change the pH of fresh water to very basic and will cause fish and other
macroinvertebrate kills.
6. If possible, bridge supports (bents) should not be placed in the stream.
7. If temporary access roads or detours are constructed, they should be removed back to original ground
elevations immediately upon the completion of the project. Disturbed areas should be seeded or
mulched to stabilize the soil and native tree species should be planted with a spacing of not more than
10'x10'. If possible, when using temporary structures the area should 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 disturbed soil.
8. A clear bank (rip rap-free) area of at least 10 feet should remain on each side of the steam underneath
the bridge.
9. Sedimentation and erosion control measures sufficient to protect water resources must be
implemented prior to any ground disturbing activities. Structures should be maintained regularly,
especially following rainfall events.
10. Bare soil should be stabilized through vegetation or other means as quickly as feasible to prevent
sedimentation of water resources.
11. All work in or adjacent to stream waters should be conducted in a dry work area. Sandbags, rock
berms, cofferdams, or other diversion structures should be used where possible to prevent excavation
in flowing water.
12. Heavy equipment should 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 should be inspected daily and maintained to prevent contamination of surface waters from
leaking fuels, lubricants, hydraulic fluids, or other toxic materials.
In most cases, we prefer the replacement of the existing structure at the same location with road closure.
If road closure is not feasible, a temporary detour should be designed and located to avoid wetland
impacts, to minimize the need for clearing, and to avoid destabilizing stream banks. If the structure will
be on a new alignment, the old structure should be removed and the approach fills removed from the 100-
year floodplain. Approach fills should be removed down to the natural ground elevation. The area
should be stabilized with grass and planted with native tree species. Tall fescue should not be used in
riparian areas. If the area that is reclaimed was previously wetlands, NCDOT should restore the area to
wetlands. If successful, the site may be used as wetland mitigation for the subject project or other
projects in the watershed.
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 contact Brian Wrenn 919-733-5715.

Re: Marion NC Bridge Replacement Project
Dear Ms. Baggett:
Bryan E. Beatty, Secretary
The North Carolina Division of Emergency Management (NCDEM) proposes to submit a project
funded by the NC Senate Bill 7 for the demolition and replacement of 226 South Smith Bridge in
the City of Marion. This bridge is located at 4870 Hwy 226 South, Marion, NC 28752. If the
project is approved, McDowell County will demolish and replace the existing bridge which has
been damaged by heavy rains and flooding during Hurricane Francis and Ivan.
Demolition activities should, for the most part, be limited to the footprint of the infrastructure.
Every effort will be made to limit the removal of or damage to existing vegetation. For
additional information regarding NCDEM policy on demolition activities, please view the
Demolition Chapter of the Hazard Mitigation Section Standard Operating Procedures on-line at
http://www.ncem.org/mitigation/document-index.htm.
The following condition will also apply:
1. The applicant communities are required to provide proof that public notification of the
project was made to effected communities pursuant to Executive Order 12898 Environmental
Justice, Executive Order 11988 Floodplain Management, and Executive Order 11990
Wetlands Protection.
Please review this proposed project under your guidelines for federally funded projects to
determine if any concerns are present or permits required. Please note that the State of North
Carolina providing 100% of the funding for this project.
Maps showing the approximate location and photos of the property have been included for your
convenience.
