MEMORANDUM
To: Ken Burleson, PE, TGS Engineers
From: Brian L. Wrenn, NCDWQ, Transportation Permitting Unit
Subject: Request for Comments for the Replacement of Bridge No. 75 on SR 1307 over Spainhour
Creek in Caldwell County, TIP Project No. B-3933
In reply to your correspondence dated June 16, 2005 (received June 22, 2005) in which you requested
comments for the referenced project, the NC Division of Water Quality has the following comments:
Project Specific Comments:
The Division of Water Quality has no specific comments regarding this project. Please refer to the
general comments below.
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
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.

SUBJECT: Caldwell County Bridge No. 75 on Broadway Street over
Spainhour Creek in the City of Lenoir, NCDOT TIP No. B-3933
TGS Engineers is starting the project development, environmental and engineering
studies for the replacement of Caldwell County Bridge No. 75 over Spainhour Creek on
Broadway Street in Lenoir. The project is included in the 2004-2010 North Carolina
Transportation Improvement Program and is scheduled for right of way in fiscal year 2004
and construction in fiscal year 2005.
Attached for your review and comments are the scoping information sheets for the
proposed project. A formal scoping meeting will not be held for this project. We would
appreciate any information you might have that would be helpful in evaluating potential
environmental impacts of the project. If applicable, please identify any permits or approvals
that maybe required by your agency. Your comments will be used in the preparation of a
federal funded Categorical Exclusion. This document will be prepared in accordance with the
National Environmental Policy Act. It is desirable that your agency responds by September
15, 2005 so that your comments can be used in the preparation of this document.
If you have any questions concerning the project, please contact ,Ken Burleson, TGS
Engineers at 919-319-8850 x-109. Please include the TIP Project Number in all
correspondence and comments.
Sincerely,
