Buffer Protection Rules (15A NCAC 2B .0233) with Additional Conditions
Dear Mr. Crisp:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.48 acres of 404/wetland (temporary impacts), 182 linear feet of perennial
stream (22 linear feet permanent impacts, 160 linear feet temporary impacts), 142 linear feet of
intermittent stream (22 linear feet permanent impacts, 120 linear feet temporary impacts), and 23,958
square feet of Zone 1 Neuse River basin protected riparian buffers, and 16,117 square feet of Zone 2
Neuse River basin protected riparian buffers, as described in your application dated February 7, 2008, and
received by the Division of Water Quality (DWQ) on February 12, 2008, with additional information
received from you on February 19, 2008, to construct the_proposed water transmission main at the site.
After reviewing your application, we have decided that the impacts are covered by~eneral Water Quality
Certification Number(s) 3699 (GC3699). The Certification(s) allows you t~.use Nationwide Permit(s)
NW 12 when issued by the US Army Corps of Engineers (USAGE). This letter shall also act as your
approved Authorization Certificate for impacts to the protected riparian buffers per 15A NCAC 2B .0233.
In addition, you should obtain or otherwise comply with any other required federal, state or local permits
before you go ahead with your project including (but not limited to) Erosion and Sediment Control, and
Non-discharge regulations. Also, this approval to proceed with your proposed impacts or to conduct
impacts to waters as depicted in your application shall expire upon expiration of the 404 or CAMA
Permit.
This approval is for the purpose and design that you described in your application. If you change your
project, you must notify us and you may be required to send us a new application. If the properly is sold,
the new owner must be given a copy of this Certification and approval letter and is thereby responsible for
complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
wetland or 150 linear feet of stream, compensatory mitigation may be required as described in 15A
NCAC 2H .0506 (h). This approval requires you to follow the conditions listed in the attached

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 measures for the project must be deigned, installed,
operated, and maintained in accordance with the most recent version o~'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 GC3705;
7. Diffuse Flow (No Review)
All constructed stormwater conveyance outlets shall be directed and maintained as diffuse flow at
non-erosive velocities through the protected stream buffers such that it will not re-concentrate
before discharging into a stream as identified within 15A NCAC 2B .0233 (5). If this is not
possible, it may be necessary to provide stormwater facilities that are considered to remove
nitrogen. This may require additional approval from this Office.
8. Certificate of Completion
Upon completion of all work approved within the 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

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 CerCification, 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
the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,

subject to review as provided in Articles 3 and 4 of G.S. 150B.
