Project-Specific Comments
For the Bridges that are Class NSW waters of the State: NCDWR is very concerned with sediment and erosion
impacts that could rzsult from these projects. NCDWR recommends that highly protective sediment and
erosion control BMPs be implemented to reduce the risk of nutrient runoffto these waters. NCDWR requests
that road design plans pravide treatment of the storm water runoff through best managemert practices as
detailed in the most recent version of NCDWR's Stormwater Best Management Practices.
For Person C�unty Bridge 50: Th�s project has surface waters classifie� as Water Supp!y Cririca! Area (CA) in
the project study area. Given the poten±ial for impacts to these !-esources during the nrojecT imnlementation, the
NCDWR requests that DO�' strictly ad'nere to iJorth Carolina regulations entit(ed "Design S[andards in
Sensitive Watersheds" (15.A NCAC 04B .0124) throughout design and construction of the project. This would
apply for any area that drainc to streams having WS CA (Water Supply Critical Areaj classificatior.s.
Should the bridge project be located within the Critical Area of a Water Supply the NCDOT will be required to
design, construct, and ma:ntain h�zardous spi!i catch basins in the project area. 'I`he number of catch hasins
installed shall b:, determined by the des:gn of the br:dge, so that :unoff wauld enter said basi�(s) raTher than

3. For the Bridges that are Class HQW (High Quality Waters of the State): This is one of the highest
�:assifi�a�:or.s for �vatzr quaiity. Fursuant to i 5A NCAC 2�I .1 QG6 ar.d 15A NGAC 2B .0224, iv� DGT wi11 be
required to obtain a State Stormwater Permit prior to construction.
4. Except for Person Bridge 50, these projects are within the Neuse or Tar-Pamlico River Basins. Riparian Buffer
ir.-,pacts s:�aiE be avaide� an� rr.•inimize� to the greatest e�iznt possible pursuant to 1� 4:�,`CA� 2B.02�� (for
Neuse) and 15A NCAC 2B.0259 (for Tar-Pamlico).
General Comments Regarding Bridge Iteplacement Projects
5. The NCDWR is very concerned with sedinent and erosion impacts that could result frorr� this project. �TC DOT
shali ad�ress these concerns by describing the potential impacts thzt may occt:r to the aquatic e7viror�nents and
any :nitigating facto:s that wouid reduce the impacts.
6. If foundation test boru.gs ai•e necessary; it shall be noted in the �ocument. Geotechnical work is approveci under
Jeneral �r01 Cer�incation Number 3883/Nation;�ide Permit No. 6 far Survey Activities.
7. If a bridge is being replaced wi'r1i a hydraulic conveyance otrier than another oridge, the NCI'iWR beiieves the use
af a 1�Taticnw i3e Derrr.it �r.ay be require3. n;ease contact the US Arrr.y Cor� o: Engineers tc det�rmine the r�qu:red
pertr,it(s).
8. 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.
9. Whenever possible, the NCDWR prefers spanning structures. Spanning structures usually do not require work

1Q. Bridge deck drains s?:all r.ot dischar�e di:ectly into the strear.l. Stormv�ater shall be directed acress the bridge
and pre-treated through site-appropriate meaiis (��assed swales, pre-formed scour hoies, vegetated buffers, etc. i
before entering the stream. Please refer to the most current version ofNCDWR Stormwater Best Management
Practices.
11. If concre�e is used during construction, a dry work area snall be maintained to prevent direct contact beriveen
curing concrete and stream water. Water that inadvertently contacts uncured concrete shali not be discharged to
surface water.s due to the potential for elevated pH and possible aquatic life and fish kills.
12. Bridge supports (betrts) snall not be placed in the sh•ea�n when possible.
13. If iemporary accPss roads or det�urs are const�-ucted, the site shall be graded to its precor.s±ruction contonrs and
eievations. Disturbed areas shall be seeded or mulched to stabilize the soil and appropriate naiive woody
s�ecies 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.
i4, Secliment and eresion control meas�ares sufficient to protect wa�er resources r.iust be irplemented �n�
maintained in accordance with the most recent version of North Carolina Sediment and Erosion Cont�ol
Ulannir�g and Design Man�.zal and the most recent version of NCSO�J0250.
15. All wor:: in or adjacer.t to stream ��ate:s shall be conducted ir. a dry wark zrea unless otherwise appraved by the
NCDWR. Approved BMP measures from the most curreiit vzrsion of NCBOT �onstruction ai�d Maintenan�e

inspected daily and maintained to prevent contamination of surface waters from leaking fuels, lubricants,
hyur�ulic �luids, or other toxi� maierials.
17. In most cases, the NCDWR 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 alignnlcr.t, tne ol� struc�u:� shali b� i•emoved an� tn� approach �i11s rer�.oved �roci tre 10i�-year �o�dplain.
Approach tills 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 i� ; iparian areas.
General Comments if Replacing the Bridge with a Culvert
i 8. Placement of culverts and otl-ier sri�uctures in waiers, streams, and wetlands shall be below the e;evation of the
streambed by one fooi for all culverts with a diameter g�eate: than -^T8 inches, ar.d 2Q percent cf the culvert
ciiameter fo: culverts having a diameier less than 48 inches, to allow Icw flow passage of water and aquatic life.
Besign and placement of culverts and other structures including temporary erosion �ontroi measures shall not
be conducted in a manner that may result in d;s-equi!ibrium of wetlands o: strearniueds or banks, adjacent to or
upstre�m and downstream of the above structures. The applicant is required to provide ev:dence ihat tne
equiii'o� ium is beiri� maititained if requested iri writi�ig by tiie NCDVJR. Ii this co�idition is u�iable io be met
due to bedrock or other limitirig features encouniered during construction, please contact ihe NCDWR for
guidar�e aa hcw tc praceed ar.d ta determine whethc: ar not a pVT�ITLIL 1T1O�If CUt:cn will be r.,quir:,d.
19. lf 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
]ifP passage.
20. Ripra� sl-ia;1 not be �Iaced in tl�e active thalweg cLamlei oi° �laced in the �treambed iiz a manner il,at preciudes

21. Any anticipaied bank stabilization associated witn culvert insiallations or extensions snould be addressed in the
�'ategorical Exclusion (CE) document. it is understood that final designs are not dete:�mined at th� time the CE
is develope�. However, the CE should discuss trie pote�ltial for bank stabilization r�ecessary due to cuivert
installation.
22. Any a�iticipated dewatering or access structures necessary far consi-ruction of briuges should be addressed in the
CE. It is understood that final_ designs are not determined at the time ih� CE is developed. However, the CE
should discuss the potential for dewatering and access measures necessary due to bridge constructioti.
i hank you for requesting our input at inis time. i he DOT is reminded that issuance of a�O 1 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 requirP additionai information, piease contact
Roo Ridings ai 91�-707-8786.
