* n/a = Total for Site is less than 1/3 acre and 150 linear feet of impact, no mitigation required
Total Buffer Impact for Project: 783 square feet.
The project shall be constructed in accordance with your application dated received November 2, 2012. After
reviewing your application, we have decided that these impacts are covered by General Water Quality Certification
Number 3883. This certification corresponds to the Nationwide Permit 3 issued by the Corps of Engineers. This
approval is also valid for the Jordan Riparian Buffer Rules (15A NCAC 213 .0267). 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- Discharge and Water Supply Watershed regulations. This approval will expire 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 NCDWQ 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 future)
exceed 150 linear feet, compensatory mitigation may be required as described in 15A NCAC 2H .0506
(h) (6) and (7). Additional buffer impacts may require compensatory mitigation as described in 15A
NCAC .0268. For this approval to remain valid, you must adhere to the conditions listed in the attached
certification(s) and any additional conditions listed below.
Condition(s) of Certification:
Project Specific Conditions
1. No instream work has been authorized at this time.
2. Strict adherence to the most recent version of NCDQT's Best Management Practices For ]Bridge Demolition
and Removal approved by the US Army Corps of Engineers.
3. Post - construction stormwater shall be designed as approved in updated November 2, 2012. If any changes
are made to the post-construction stormwater design, the Division of Water Quality shall be contacted for
approval of the changes.
4. No drill slurry or water that has been in contact with uncured concrete shall be allowed to enter surface
waters. This water shall be captured, treated, and disposed of properly.
5. All riparian buffers impacted by the placement of temporary fill or clearing activities shall be restored to the
preconstruction contours and revegetated. Maintained buffers shall be permanently revegetated with non -
woody species by the end of the growing season following completion of construction. For the purpose of
this condition, maintained buffer areas are defined as areas within the transportation corridor that will be
subject to regular NCDOT maintenance activities including mowing. The area with non- maintained buffers
shall be permanently revegetated with native woody species before the next growing season following
completion of construction.
6. Pursuant to 15A NCAC 21=3 .6267, sediment and erosion control devices shall not be placed in Zone 1 of any
Jordan Buffer without prior approval by NCDWQ. At this time, NCDWQ has approved no sediment and
erosion control devices in Zone 1, outside of the approved project impacts, anywhere on this project.
Moreover, sediment and erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone
I is not compromised and that discharge is released as diffuse flow.
General Conditions
7. 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.
8. 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.
9. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit drawings
submitted for approval.
10. Heavy 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 maintained 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. A copy of this Water Quality Certification shall be maintained on 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,
15. The outside buffer, wetland or seater boundary located within the construction corridor approved by this
authorization shall be clearly marked by highly visible fencing prior to any land disturbing activities. Impacts
to areas within the fencing are prohibited unless otherwise authorized by this certification.
16, 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.
17. The Permittee shall report any violations of this certification to the Division of Water Quality within 24 hours
of discovery.
18. Upon completion of the project (including any impacts at associated borrow or waste sites), the NCDOT
Division Engineer shall complete and return the enclosed "Certification of Completion Form" to notify
NCDWQ when all work included in the 401 Certification has been completed.

19. Native riparian vegetation must be reestablished in the riparian areas within the construction limits of the
project by the end of the growing season following completion of construction.
20. There shall be no excavation from, or waste disposal into, jurisdictional wetlands or waters associated with
this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or
borrow sites, be located in wetlands or streams, compensatory mitigation will be required since that is a direct
impact from road construction activities.
21. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved
by this Certification.
If you wish to contest any statement in the attached Certification you must file a petition for an administrative
hearing. You may obtain the petition form from the office of Administrative hearings. You must file the petition
with the office of Administrative Hearings within sixty (60) days of receipt of this notice. A petition is considered
