Orange County, and Bridge nos. 44 (SR 2336), 86 (SR 2598), and 143 (SR 1321) in
Rockingham County.
Reference your correspondence dated September 17, 2010 in which you requested comments for the
referenced projects. The NCDWQ offers the following comments.
Project Specific Comments:
Bridge No. 32 (SR 1582) over Buttermilk Creek in Alamance County
*Potential impacts to Buttermilk Creek
1. Buttermilk Creek are WSII, HQW; NSW waters of the State. NCDWQ is very concerned with
sediment and erosion impacts that could result from this project. NCDWQ recommends that highly
protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff
to Buttermilk 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'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 classifications 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 Basin. Riparian buffer impacts shall be avoided and
minimized to the greatest extent possible pursuant to 15A NCAC 2B .0267.
Bridge No. 66 (SR 1910) over Quaker Creek in Alamance County
*Potential impacts to Quaker Creek
4. Quaker Creek are WSII, HQW; NSW waters of the State. NCDWQ is very concerned with sediment
and erosion impacts that could result from this project. NCDWQ recommends that highly protective
sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to Quaker
Creek. NCD WQ requests that road design plans provide treatment of the storm water runoff through
best management practices as detailed in the most recent version ofNCDWQ's Stormwater Best
Management Practices.

section of Little Troublesome Creek is upstream of the project.
Bridge No. 143 (SR 1321) over Beaver Island Creek in Rockingham County
*Potential impacts to Beaver Island Creek. No project specific comments.
General Project Comments:
1. Proposed impacts suggest that this project will be permitted using a Nationwide 3 from the US Army
Corps of Engineers. NCDWQ would like to respectively remind NCDOT that WQC 3687, or its
most recent equivalent, will also be required. NCDOT shall be in compliance with all of its
applicable conditions.
2. DWQ understands that these bridges will be replaced using an off-site detour, if at any time these
plans change, DWQ shall be contacted to determine if this project shall remain in the Low-Impact
Bridge Replacement process.
3. 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 Stornrtvater Best Management Practices, such as grassed swales,
buffer areas, preformed scour holes, retention basins, etc.
4. 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 {I 5A NCAC 2H.0506(h)}, mitigation will be required for impacts
of greater than 150 linear 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.
5. 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.
6. 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.
7. 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.
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 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.
11. If foundation test borings are necessary; it should be noted in the document. Geotechnical work is
approved under General 401 Certification Number 3624/Nationwide Permit No. 6 for Survey
Activities.
12. 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.
13. 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.
14. Sediment and erosion control measures shall not be placed in wetlands and streams.
15. Borrow/waste areas shall avoid wetlands to the maximum extent practical. Impacts to wetlands in
borrow/waste areas could precipitate compensatory mitigation.
16. 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.
17. 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].
