Dear Dr. Thorpe:
You have our approval, in accordance with the conditions listed below, for the following impacts for the purpose of
replacing Bridge 158 in Durham County: -
Neuse Riparian Buffer Impacts
Site Zone 1 minus =Zone 1 Zone 1 Buffer Zone 2 minus =Zone 2 Zone Z Buffer
Impact Wetlands Buffers (not Mitigation Impact Wetlands Buffers Mitigation
(sq ft) in Zone 1 wetlands) Required (sq ft) in Zone 2 (not Required (using
(sq ft) (sq ft) (using 3:1 ratio) (sq ft) wetlands) 1.5:1 ratio)

Totals 2,344 0 2,344 0 1,013 0 1,013 0
* n/a =Total for Site is less than 1/3 acre and 1501ineaz feet of impact, no mitigation required
Total Buffer Impact for Project: 3,357 square feet.
The project shall be constructed in accordance with your application dated received June 11, 2007. This approval is
valid for the Neuse Riparian Buffer Rules (15A NCAC 2B.0233). 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 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 future) exceed 1501inear feet, compensatory mitigation maybe required as
described in 15A NCAC 2H .0506 (h) (6) and (7). For this approval to remain valid, you must adhere to the
conditions listed below.
Conditions of Certification:
1. The post-construction removal of any temporary bridge structures must return the project site to its
preconstruction contours and elevations. The impacted areas shall be revegetated with appropriate native species.

2. Strict adherence to 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 this approval.
3. Bridge deck drains should not discharge directly into the stream. Stormwater should 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 Stormwater Best Management Practices.
4. 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 DOT
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.
5. Pursuant to NCACISA 2B.0233(6), sediment and erosion control devices shall not be placed in Zone 1 of any
Neuse Buffer without prior approval by the NCDWQ. At this time, the 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 1 is not
compromised and that discharge is released as diffuse flow. .
6. All Stormwater runoff shall be directed as sheetflow through stream buffers at nonerosive velocities, unless
otherwise approved by this certification.
7. If concrete is used during construction, a dry work area should be maintained to prevent direct contact between
curing concrete and stream water. Water that inadvertently contacts uncured concrete should not be discharged to
surface waters due to the potential for elevated pH and possible aquatic life and fish kills.
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 should not be modified.
Disturbed floodplains and streams should be restored to natural geomorphic conditions.
10. All work in or adjacent to stream waters shall be conducted in a dry work area. 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.
11. 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.
12. 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.
13. No rock, sand or other materials shall be dredged from the stream channel except where authorized by this
certification.
14. Discharging hydroseed mixtures and washing out hydroseeders and other equipment in or adjacent to surface
waters is prohibited.

15. A copy of this Neuse Buffer Approval shall be posted on the construction site at all times. In addition, the
Neuse Buffer Approval and all subsequent modifications, if any, shall be maintained with the Division Engineer and
the on-site project manager.
16. The outside buffer, wetland or water 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.
17. Upon completion of the project, the NCDOT Division Engineer shall complete and return the enclosed
"Certification of Completion Form" to notify DWQ when all work included in the approval has been completed.
18. Native riparian vegetation must be reestablished within the construction limits of the project by the end of the
growing season following completion of construction.
19. 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 be located in wetlands or streams,
compensatory mitigation will be required since that is a direct impact from road construction activities.
20. 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 Control Manual. The devices shall be maintained on all
construction 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 measures 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 irnplementation must comply with the reclamation in accordance with
the requirements of the Sedimentation Pollution Control Act.
21. Sediment and erosion control measures shall not be placed in wetlands or waters unless otherwise approved by
this Certification. If placement of sediment and erosion control devices in wetlands and waters is unavoidable, they
shall be removed and the natural grade restored upon completion of the project.
