Instructions for completion of worksheet (located on page 2): Begin by determining the most appropriate ecoregion based on
location, terrain, vegetation, stream classification, etc. Every characteristic must be scored using the same ecoregion. Assign points
to each characteristic within the range shown for the ecoregion. Page 3 provides it brief description of how to review the
characteristics identified in the worksheet. Scores should reflect an overall assessment of the stream reach under evaluation. If a
characteristic cannot be evaluated due to site or weather conditions, enter 0 in the scoring box and provide an explanation in the
comment section. Where there are obvious changes in the character of a stream under review (e.g., the stream flows from a pasture
into a forest), the stream may be divided into smaller reaches that display more continuity, and a separate form used to evaluate each
reach. The total score assigned to a stream reach must range between 0 and 100, with a score of 100 representing a stream of the
highest quality.
Total Score (from reverse): J Comments:
Evaluator's Signature Date '
This channel evaluation form is intended to be used only as a guide to assist landowners and enviromnental professionals in
gathering the data required by the Unitcd States Army Corps of Engineers to make it preliminary assessment of stream
quality. The total score resulting from the completion of this form is subject to USACE approval and does not imply a
particular mitigation ratio or requirement. Form subject to change version 06103. To Comment, please call 919-876-8441 x 26.

1. The Corps of Engineers believes that there may be jurisdictional waters of the United
States on the subject site, and the permit applicant or other affected party who
requested this preliminary JD is hereby advised of his or her option to request and
obtain an approved jurisdictional determination (JD) for that site. Nevertheless, the
permit applicant or other person who requested this preliminary JD has declined to
exercise the option to obtain an approved JD in this instance and at this time.
2. In any circumstance where a permit applicant obtains an individual permit, or a
Nationwide General Permit (NWP) or other general permit verification requiring "pre-
construction notification" (PCN), or requests verification for a non-reporting NWP or
other general permit, and the permit applicant has not requested an approved JD for the
activity, the permit applicant is hereby made aware of the following: (1) the permit
applicant has elected to seek a permit authorization based on a preliminary JD, which
does not make an official determination of jurisdictional waters; (2) that the applicant
has the option to request an approved JD before accepting the terms and conditions of
the permit authorization, and that basing a permit authorization on an approved JD
could possibly result in less compensatory mitigation being required or different special
conditions; (3) that the applicant has the right to request an individual permit rather than
accepting the terms and conditions of the NWP or other general permit authorization;
(4) that the applicant can accept a permit authorization and thereby agree to comply
with all the terms and conditions of that permit, including whatever mitigation
requirements the Corps has determined to be necessary; (5) that undertaking any
activity in reliance upon the subject permit authorization without requesting an approved
JD constitutes the applicant's acceptance of the use of the preliminary JD. but that
either form of JD will be processed as soon as is practicable; (6) accepting a permit
authorization (e.g., signing a proffered individual permit) or undertaking any activity in
reliance on any form of Corps permit authorization based on a preliminary JD
constitutes agreement that all wetlands and other water bodies on the site affected in
any way by that activity are jurisdictional waters of the United States, and precludes any
challenge to such jurisdiction in any administrative or judicial compliance or
enforcement action, or in any administrative appeal or in any Federal court; and (7)
whether the applicant elects to use either an approved JD or a preliminary JD, that JD
will be processed as soon as is practicable. Further, an approved JD, a proffered
individual permit (and all terms and conditions contained therein), or individual permit
denial can be administratively appealed pursuant to 33 C.F.R. Part 331, and that in any
administrative appeal, jurisdictional issues can be raised (see 33 C.F.R. 331.5(a)(2)). If,
during that administrative appeal, it becomes necessary to make an official
determination whether CWA jurisdiction exists over a site, or to provide an official
delineation of jurisdictional waters on the site, the Corps will provide an approved JD to
accomplish that result, as soon as is practicable. This preliminary JD finds that there
"may be" waters of the United States on the subject project site, and identifies all
aquatic features on the site that could be affected by the proposed activity, based on the
following information:

MEMORANDUM
TO: Brenna Poole, NCDOT Bridge Project Development Unit
FROM: Rob Ridings, NC Division of Water Quality, Transportation Permitting Unit
SUBJECT: Scoping Review of NCDOT's Proposed Bridge Replacement Projects: B- 5124 (over Swift Creek in
Nash County) and B-4933 (over Tar River in Edgecombe County).
In reply to your correspondence received September 9, 2009 in which you requested comments for the above referenced
projects, the NC Division of Water Quality offers the following comments:
Project-Specific Comments
1. Swift Creek is class C; NSW waters of the State. Tar River is class WS-IV; NSW waters of the State. DWQ is
very concerned with sediment and erosion impacts that could result from this project. DWQ recommends that
highly protective sediment and erosion control BMPs be implemented to reduce the risk of nutrient runoff to these
waters. DWQ requests that road design plans provide treatment of the storm water runoff through best management
practices as detailed in the most recent version of NC DWQ Stormwater Best Management Practices.
2. These projects are within the Tar River Basin. Riparian buffer impacts shall be avoided and minimized to the
greatest extent possible pursuant to 15A NCAC 2B.0259.
3. 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 are not determined at the time the CE is
developed. However, the CE should discuss the potential for bank stabilization necessary due to culvert installation.
An adequate bank stabilization amount should also be applied for in the permit applications, to prevent the need of a
later permit modification.
4. 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 and
permit applications should discuss the potential for dewatering and access measures necessary due to bridge
construction.

General Comments Regarding Bridge Replacement Projects
1. DWQ is very concerned with sediment and erosion impacts that could result from this project. NC DOT 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.
2. 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.
3. If a bridge is being replaced with a hydraulic conveyance other than another bridge, DWQ believes the use of a
Nationwide Permit may be required. Please contact the US Army Corp of Engineers to determine the required
permit(s).
4. 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.
5. Whenever possible, the DWQ prefers spanning structures. Spanning structures usually do not require work within
the stream 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, do not block fish
passage and do not block navigation by canoeists and boaters.
6. 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 NC DWQ Stormwater Best Management Practices.
7. 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.
8. Bridge supports (bents) shall not be placed in the stream when possible.
9. 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.
10. 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.
11. All work in or adjacent to stream waters shall be conducted in a dry work area unless otherwise approved by NC
DWQ. 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.
12. 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.
13. In most cases, the DWQ 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.
General Comments if Replacing the Bridge with a Culvert
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 culverts 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 banks, adjacent to or upstream and down
stream of the above structures. The applicant is required to provide evidence that the equilibrium is being
maintained if requested in writing by DWQ. If this condition is unable to be met due to bedrock or other limiting
features encountered during construction, please contact the NC DWQ for guidance on how to proceed and to
determine whether or not a permit modification will be required.
2. If multiple pipes or barrels are required, they shall be designed to mimic natural stream cross section as closely as
possible including pipes or barrels at flood plain elevation and/or sills where appropriate. Widening the stream
channel shall be avoided. Stream channel widening at the inlet or outlet end of structures typically decreases water
velocity causing sediment deposition that requires increased maintenance and disrupts aquatic life passage. .
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 shall be properly designed, sized and installed.
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 Rob Ridings at 919-733-
9817.
