2. No Waste, Spoil, Solids, or Fill of Any Kind
No waste, spoil, solids, or fill of any kind shall`occur in wetlands, waters, or riparian areas beyond
the footprint of the impacts depicted in the Pre-Construction Notification. All construction
activities, including the design, installation, operation, and maintenance of sediment and erosion
control Best Management Practices, shall be performed so that no violations of state water quality
standards, statutes, or rules occur.
3. 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 measilr'e~'`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. Sufficient materials required for stabilization and/or repair of erosion control measures and
stormwater routing and treatment shall be on site at all times.
4. Sediment and Erosion Control Measures '' ' '
Sediment and erosion control measures shall not be placed in wetlands or waters to the maximum
extent practicable. If placement of sediment and erosion control devices in wetlands and waters is
unavoidable, they shall be removed-and the natural grade restored within six months of the date that
the Division of Land Resources has released the project;
5. Deed Notifications
Deed notifications or similar mechanisms shall. be placed on all retained jurisdictional wetlands,
waters and protective buffers in order to assure"compliance for future Wetland, water and buffer
impact. These mechanisms shall be put in place at the time of recording of the property, or of
individual lots, whichever is appropriate. A sample deed notification can be downloaded from
the 401/Wetlands Unit web site at http://h2o.enr.state.nc.us/ncwetlands. The text of the sample
deed notification may be modified as appropriate to suit to this project.
6. Protective Fencing
The outside buffer, wetland or water boundary and along the construction corridor within these
boundaries approved under this authorization shall be clearly marked with orange warning fencing
(or similar high visibility material) for the areas that have been approved to .infringe within the
buffer, wetland or water prior to any land disturbing activities to ensure compliance with 15A
NCAC 2B .0233 and GC3631;

7. Culvert Installation
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
(http•//www.ncdot.or doh/operations/BMP manual/downloadBMP Manual.pdf)
such as sandbags, rock berms, cofferdams and other diversion structures shall be used to prevent
excavation in flowing water.
Culverts required for this project shall be installed in such a manner that the original stream
profiles are not altered. Existing stream dimensions (including the cross section dimensions,
pattern, and longitudinal profile) must be maintained above and below locations of each culvert.
Culverts shall be designed and installed to allow for aquatic life movement as well as to prevent
head cutting of the streams. If any of the existing pipes are or become perched, the appropriate
stream grade shall be re-established or, if the pipes installed in a perched manner, the pipes shall
be removed and re-installed correctly.
Culvert(s) shall not be installed in such a manner that will cause aggradation or erosion of the
stream up or down stream of the culvert(s). Existing stream dimensions (including the cross section
dimensions, pattern and longitudinal profile) shall be maintained above and below locations of each
culvert. Therefore, you must provide plans with adequate details that indicate that the current
stability of the stream will be maintained or enhanced. You must receive written approval from this
Office for the above plans before the culvert(s) is installed. Culvert(s) must be installed according
to approved plans.
Placement of culverts and other structures in waters, streams, and wetlands must be placed below
the elevation of the streambed by one foot for all culverts with a diameter greater than 48 inches,
and 20 percent of the culvert diameter for culverts having a diameter less than 48 inches, to allow
low flow passage of water and aquatic life. Design and placement of culverts and other structures
including temporary erosion control measures shall not be conducted in a manner That may result
in dis-equilibrium of wetlands or streambeds or banks, adjacent to or upstream and down stream
of the above structures. The applicant is required to provide evidence that the equilibrium shall be
maintained if requested in writing by DWQ.
The establishment of native, woody vegetation and other soft stream bank stabilization techniques
must be used where practicable instead of rip rap or other bank hardening methods. If rip-rap is
necessary, it shall not be placed in the stream bed, unless specifically approved by the Division of
Water Quality.
Installation of culverts in wetlands must ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions.
Upon completion of the project, the Applicaptshall complete and return the enclosed "Certificate
of Completion" form to notify NCDWQ when all work included in the §401 Certification has
been completed. The responsible party shall complete the attached form and return it to the
401/Wetlands Unit of the NC Division of Water Quality upon completion of the project. Please
send photographs upstream and downstream of each culvert site to document correct installation
along with the Certificate of Completion form.

8. Diffuse Flow (DWQ Reviewed Plans)
All stormwater shall be directed as diffuse flow at non-erosive velocities through the protected
stream buffers and will not re-concentrate before discharging into the stream as identified within
15A NCAC 2B .0233(5)
In an effort to comply with the diffuse flow provision of the Buffer Rule (15A NCAC 02B
.0233(5)), you have provided the DWQ with level spreader designs. The DWQ believes that if
implemented, as per these plans, diffuse flow will be achieved. However, if diffuse flow as per
15A NCAC 02B .0233(5) has not been achieved, then the DWQ shall be notified and corrective
actions to restore diffuse flow shall be taken if necessary to impede the formation of erosion
gullies. At no time shall stormwater from the proposed development be piped directly through
the buffer without prior written authorization by DWQ.
The structural stormwater practices as approved by this Office, as well as drainage patterns, must
be maintained in perpetuity. No changes to the structural stormwater practices shall be made
without written authorization from the Division of Water Quality. stormwater easements shall be
recorded for a distance of at least 10 feet on each side of all stormwater conveyances on all lots
containing these structures including future dcd~~~ for maintenance. The stormwater easements
shall allow for the ability to maintain the structures, perform corrective actions as described
above and shall provide protection of the structures from potential alternations by future property
owners.
An Operation & Maintenance (O&M) agreement signed by the current landowner must be
approved by the DWQ. This O&M agreement must transfer with the sale of the land or transfer
of responsibility for the stormwater facilities and the DWQ must be notified of every transfer.
9. Certificate of Completion
Upon completion of all work approved within he 401 Water Quality Certification or applicable
Buffer Rules, and any subsequent modifications, the applicant is required to return the attached
certificate of completion to the 401 Oversight/Express Review Permitting Unit, North Carolina
Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650.
Violations of any condition herein set forth may result in revocation of this Certification and may result in
criminal and/or civil penalties. The authorization to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application and as authorized by this Certification, shall expire upon
expiration of the 404 or CAMA Permit.
If you do not accept any of the conditions of this Certification (associated with the approved wetland or
stream impacts), 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, which conforms to Chapter 150B of
