3 As state in your e mail correspondence DWQ piovided project specific comments to NCDOT for
this proposed bridge replacement in a letter dated August 31 2009 In addition to those comments
we also would also like to offer the following comments
4 Wheeler Cieek aie class SA HWQ 303(d) waters of the State Wheeler Creek is on the 303(d) list
for impaued use foi aquatic life due to loss of use for shellfishing 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 Wheeler Creek NCDWQ__
requests that road design plans provide treatment of the stoim water runoff through best
management practices as detailed in the most recent version of NCDWQ Stormwater Best
Management Practices
5 Based on field obseivation lengthening the biidge to the West appears to minimize impacts and
provide a greater benefit to the system
BD 5103R, Bridge 64 over Jinny's Branch, Brunswick County
6 Review of the project reveals the presence of surface waters classified as C Sw HQW High Quality
Waters of the State in the project study area This is one of the highest classifications foi water
quality Pursuant to 15A NCAC 2H 1006 and 15A NCAC 2B 0224 NCDOT will be requiied to
obtain a State Stormwater Permit prior to construction except in North Carolina s twenty coastal
counties
7 Based on field obseivation widening the bridge to West and lengthening to the South appears to
minimize impacts and piovide a greater benefit to the system
BD 5103S Bridge 77 over South River Overflow, Sampson County
BD 5103T Bridge 78 over South River, Sampson County
Review of the project reveals the presence of surface waters classified as C Sw Outstanding
Resource Waters of the State in the project study area The water quality classification of C Sw
ORW is one of the highest classifications in the State NCDWQ is extremely concerned with any
impacts that may occur to streams with this classification It is preferred that these resources be
avoided if at all possible If it is not possible to avoid these resources the impacts shall be
miminized to the greatest extent possible Given the potential for impacts to these resources dui ing
the pioject implementation the NCDWQ iequests that NCDOT sti ictly adhere to North Carolina
regulations entitled Design Standards in Sensitive Watersheds (15A NCAC 04B 0124)
throughout design and construction of the pioject Pursuant to 15A NCAC 2H 1006 and l5A
NCAC 2B 0224 NCDOT will be required to obtain a State Stoimwater Permit prior to
construction except in North Carolina s twenty coastal counties
9 Based on field observation lengthening the Bridge 77 to the South and widening to the West
appears to minimize impacts and provide a greatei benefit to the system
10 Based on field observation lengthening the Bridge 78 to the North appeais to minimize impacts and
pi ovidea gi eater benefit to the system
General Comments Regarding Bridge Replacement Projects
11 NCDWQ is very concerned with sediment and erosion impacts that could result fionn this pioJect
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

12 If foundation test boiungs are necessary it shall be noted to the document Geotechnical work is
approved under General 401 Certification Number 3687/Nationwide Permit No 6 for Suivey
Activities
13 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 Coip of
Engineers to determine the required permit(s)
_ 14 If the_old_biidge is removed no discharge of bridge mate►ial into surface waters is allowed unless
otherwise authorized by the US ACOE Strict adherence to the Coips of Engineers guidelines for
bridge demolition will be a condition of the 401 Water Quality Certification
15 Whenever possible NCDWQ prefers spanning structures Spanning structures usually do not
require work within the stream or grubbing of the stieambanks and do not require stream channel
realignment The horizontal and vertical clearances provided by bi idges 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
16 Bridge deck drams shall not discharge duectly into the stream Stormwater shall be duected across
the bridge and pie treated thiough site app►opriate means (glassed swales pie foinned scour holes
vegetated buffet s etc ) before enter i ng the sti earn Please i efei to the most cui i ent version of
NCDWQ s Stormwater Best Management Practices
17 If concrete is used during constt action a dry work ai ea shall be maintained to pi event du ect 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
18 If temporary access roads of detours are constructed the site shall be graded to its preconstrirction
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 cleated but not grubbed Clearing the area with chain saws mowe►s bush hogs of other
mechanized equipment and leaving the stumps and root mat intact allows the area to to vegetate
naturally and minimizes soil disturbance
19 Sediment and erosion control measures sufficient to protect water ►esouices 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
20 All work in of adjacent to stream waters shall be conducted in a dry work area unless otherwise
approved by NCDWQ Appi oved BMP measui es fi om the most current vet stun of NCDOT
Construction and Maintenance Activities manual such as sandbags rock beinns cofferdams and
other diversion structures shall be used to prevent excavation in flowing water
21 Heavy equipment shall be operated fiom 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 lubi►cants hydraulic fluids of other toxic mater ials
22 In most cases the NCDWQ piefeis the replacement of the existing st►uctu►e at the same location
with load closure If road closure is not feasible a temporary detoill shall be designed and located
to avoid wetland impacts mm►mize the need for cleaung and to avoid destabilizing stream banks
If the structure will be on a new alignment the old structuie shall be removed and the app►oach fills
removed from the 100 year floodplarn 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
23 Any anticipated dewatering or access structures necessary fot construction of budges should be
addressed in the CE It is understood that final designs at e not deter mined at the tune the CE is
developed However the CE should discuss the potential for dewatering and access measuies
necessary due to bridge construction
_ 24__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 ale generally
authorized in accordance with the conditions of Geneial 401 Certification Number 3819/Nationwide
Peimit No 12 for Utility Lune Activities
Thank you foi iequesting our input at this time NCDOT is ieminded that issuance of a 401 Water
Quality Certification requires that appropriate measuies be instituted to ensuie that watei quality
standaids are met and designated uses ate not degraded or lost If you have any questions of iequire
additional information please contact Mason Herndon at [phone]
