TIP B-5202
APPROVAL of 401 WATER QUALITY CERTIFICATION with ADDITIONAL CONDITIONS
Mr. Jay Johnson
North Carolina Deparmten[ of Transportation
P.O. Box 1587
Greenville, NC 27835
Dear Mr. Johnson:
You have our approval, in accordance with the conditions listed below, for the following impacts for the purpose of
replacing Bridge No. 18 over the Intercepting Canal on NC 99 in Beaufort County:
Stream Stream
Site Number linear (t s uare ft
Bridge l8 125* 208**
*impacts due to tetaining wall
**impacts due to bridge pilings
The project shall be constructed m accordance with your application dated received June 21, 2011. After reviewing
your application, we have decided that these impacts are covered by General Water Quality Certification Number
3687. This certification corresponds to the. Nationwide Permit 3 issued by the Corps of Engineers. In addition, you
should acquire any other federal, state or local permits before you proceed with your project including (but not
limited to) Sediment and Erosion Control, Non-Dischazge and Water Supply Watershed regulations. This approval
will expve with the accompanying 404 permit.
This approval is valid solely for the purpose and design described in your application (unless modified below).
Should your project change, you must notify the DWQ and submit a new application. if the property is sold, the
new owner must be given a copy of this Certification and approval letter, and is thereby responsible for complying
with all the conditions. If total wetland fills for this project (now or in the future) exceed one acre, or of total
impacts to streams (now or in the futtre) exceed 150 linear feet, compensatory mitigation may be required as
described in 1 SA NCAC 2H .0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
conditions listed in the attached certification.
1. The issuance of this certification does not exempt the Permittee from complying with any and all statutes, rules,
regulations, or ordinances that may be imposed by other government agencies (i.e. local, state, and federal)
having jurisdiction, including but not limited to applicable buffer rules, stormwater management rules, soil
erosion and sedimentation control requirements, etc.
2. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours of
discovery

3. The permittee and its authorized agents shall conduct its activities in a manner consistent with State water
quality standards (including any requirements resulting from compliance with §303 (d) of the Clean Water Act)
and any other appropriate requirements of State and Federal law. If DWQ determines that such standards or
laws are no[ being met (including the failure to sustain a designated or achieved use) or that State or federal law
is being violated, or that further conditions are necessary to assure compliance, DWQ may reevaluate and
modify this certification.
4. The Permittee shall ensure that the final design drawings adhere to the certification and to the drawings
submitted for approval.
5. Erosion and sediment control practices must be in full compliance with all specifications governing the proper
design, installation and operation and maintenance of such Best Management Practices in order to protect
surface waters standards:
a. The erosion and sediment control measures for the project must be designed, installed, operated, and
maintained in accordance with the most recent version of the North Carolina Sediment and Erosion
Control Planning and Design Manual.
b. The design, installation, operation, and maintenance of the sediment and erosion control measures
must be such that they equal, or exceed, the requirements specified in the most recent version of the
North Carolina Sediment and Erosion Convo/ Manual. The devices shall be maintained on all
conshtrction sites, borrow sites, and waste pile (spoil) projects, including contractor-owned or leased
borrow pits associated with the project.
c. For borrow pit sites, the erosion and sediment control measrues must be designed, installed, operated,
and maintained in accordance with the most recent version of the North Carolina Surface Mining
Manual.
d. The reclamation measures and implementation must comply with the reclamation in accordance with
the requirements of the Sedimentation Pollution Control Act.
6. 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 dischazged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
7. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for stream
stabilization shall be placed in stream channels in such a manner that it does not impede aquatic life passage.
8. During the construction of the project, no staging of equipment of any kind is permitted in waters of the U.S., or
protected riparian buffers.
9. The dimension, pattern and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams shall be restored to natural geomorphic conditions.
10. Heary equipment shall be operated from the banks rather than in the stream channel in order to minimize
sedimentation and reduce the introduction of other pollutants into the stream.
11. All mechanized equipment operated near surface waters must be regularly inspected and maintaided to prevent
contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.
12. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
13. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.

14. The outside buffer, wetland or water boundary located within the construction corridor approved by this
certification shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts to
areas within [he fencing are prohibited unless otherwise authorized by this certification.
15. Native riparian vegetation (ex. list trees and shmbs native to your geographic region) must be reestablished
within the conswction limits of the project by the end of the Bowing season following completion of
construction.
16. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with this
certification without appropriate modification. Should waste or borrow sites, or access roads to waste or borrow
sites, be located in wetlands or streams, compensatory mitigafion will be required since that is a direct impact
from road construction activities.
] 7. Strict adherence [o the most recent version of NCDOT's Best Management Practices For Bridge Demolition
and Removal approved by the US Army Corps of Engineers is a condition of the 401 Water Quality
Certification.
18. Bridge piles and bents shall be constructed using driven piles (hammer or vibratory) or drilled shaft construction
methods. More specifically, jetting or other methods of pile driving are prohibited without prior written
approval from NCDWQ.
19. Bridge deck drains shall not dischazge directly into the stream. Stormwater shall be directed across the bridge
and pre-treated through site-appropriate means (grossed swales, pre-formed scour holes, vegetated buffers, etc.)
before entering the stream. Please refer to the most current version of Stormwater Best Management Practices.
20. Riprap shall not be placed m the active thalweg channel or placed in the streambed in a manner that precludes
aquatic life passage. Bioengineering boulders or swctures should be properly designed, sized and installed.
2 ]. Upon completion of the project (including any impacts at associated borrow or waste site), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify DWQ
when all work included in the 401 Certification has been completed.
22. A copy of this Water Quality Certification shall be maintained on site at the construction site at all times. In
addition, the Water Quality Certification and all subsequent modifications, if any, shall be maintained with the
Division Engineer and the on-site project manager.
If you do not accept any of the conditions of this certification, you may ask for an adjudicatory hearing. You must
act within 60 days of the date that you receive this letter. To ask for a hearing send a written petition that conforms
to Chapter 1 SOB of [he North Carolina Geneml Statutes to the Office of Administrative Hearings, 6714 Mail Service
