Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River
B ffer Protection Rules i(15A NCAC 2B.02ii3) with Additional Conditions
j D' ar Mr. Alexander:
I
41 Y (u have our approval, in accordance with the attached conditi ns and those listed below, to place fill
wi hin or otherwise impact 25 feet of streams and 250 square fe t (ft) of protected riparian buffers for the
p ose of repairing a footing of an existing aerial sewer line and\stabilizing the stream bank at the
su ject property, as described within your application dated November 18, 2004 and received by theN.C.
D' sion of Water Quality (DWQ) on November 19, 2004. After reviewing your application, we have
I decided that the impacts qe covered by General Water Quality Certification Number(s) 3399 (GC3399).
T Certhcation(s) allows you to use Nationwide Permit(s) 13 when issued by the US Army Corps of
E ineers (USAGE).. This letter shall also act as your approved Authori
zation 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
ap roval to proceed with your proposed impacts or to conduct impacts to waters as depicted in
yo r application shall expire upon expiration of the 404 Permit.
( iTb.s approval is for the purpose and design thax you described in your application. If you change your
I :pr `ect, you must notify u and you may be required to send us 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
1 complying with all conditions. If total fills for this project (now or in the future) exceed one acre of
we land or 150 linear feet of stream, compensatory mitigation may be required as described in 15A
N ,,AC 2H.0506 (h). This approval requires you to follow the conditions listed in the attached
ce ification and any additional conditions listed below.
Th Additional Conditions of the Certification are:
1. I' Impacts Approved - Tine following impacts are hereby approved as long as all of the other specific
and general conditions) of this Certification ?(or Isolated Wetland Permit) are met. No other impacts
t are approved including incidental impacts:

2. Temporary Sand Bags - The temporary sandbags installed o divert the stream around the footing
shall be removed and the original stream flow shall be rest¢ ed immediately following construction.
3. Erosion & Sediment Control Practices - Erosion and sediri nt control practices must be in full
compliance with all specifications governing the proper,,, de5'gn, installation and operation and
maintenance of such Best Management Practices in order t 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 ost recent version of the North Carolina
Sediment and Erosion Control Planning and Desi n Manual.
b. The design, installation, operation, and maintean e of the sediment and erosion control
measures must be such that they equal, or exceed,' he requirements specified in the most
recent version of the North Carolina Sediment Iiii an 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 il associated with the project.
4'. No Waste, Spoil, Solids, or Fill of Any Kind- No was , spoil, solids, or fill of any kind shall occur`
in wetlands, waters, or riparian areas beyond the footp int of the impacts depicted in the Pre-
Construction Notification. All construction activities, eluding the design, installation, operation,
and maintenance of sediment and erosion control Best nagement Practices, shall be performed
so that no violations of state water quality standards, si tines, or rules occur.
5. No Sediment & Erosion Control Measures w/n Wetlands or Waters - 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.
6. Certificate of Completion - Upon completion of all wi k approved within the 401 Water Quality
Certification or applicable Buffer Rules, and, any subsequent modifications, the applicant is

VIII. Mitigation
WQ - In accordance with 15A NCAG 2H .0500, mitigation may be required by the NC
ivision of Water Quality for projects involving greater than or equal to one acre of impacts to
reshwater wetlands or greater than or equal to 150 linear feet of total impacts to perennial
treams.

}
i
SA CE - In accordance with the Final Notice of Issuance and Modification of Nationwide
P rmits, published in the Federal Register on March 9, 2000, mitigation will be required when
necessary to ensure that adverse effects Ito the aquatic environment are minimal. Factors
including size and type of proposed impact and function and relative value of the impacted
aquatic resource will be considered in determining acceptability of appropriate and practicable
mitigation as proposed. Examples of mitigation that may be appropriate and practicable include,
but are not limited to: reducing the size of the project; establishing and maintaining wetland
and/or upland vegetated buffers to protect open waters such as streams; and replacing losses of
a uatic resource functions and values by creating, restoring, enhancing, or preserving similar
ffinctions and values, preferable in the same watershed.
If mitigation is required for this project, a copy of the mitigation plan must be attached in order
for USACE or DWQ to consider the application complete for processing. Any application
lacking a required mitigation plan or NCWRP concurrence shall be placed on hold as
i complete. An applicant may also choose!to review the current guidelines for stream restoration
ii DWQ's Draft Technical Guide for Stream Work in North Carolina, available at
Provide a brief description of the proposed mitigation plan. The description should provide
as much information as possible, including, but not limited to: site location (attach directions
and/or map, if offsite), affected stream and river basin, type and amount (acreage/linear feet)
of mitigation proposed (restoration, enhancement, creation, or preservation), a plan view,
preservation mechanism (e.g., deed! restrictions, conservation easement, etc.), and a
description of the current site conditions and proposed method of construction. Please attach
a separate sheet if T; ore space is needed.
Mitigation may also be made by payment into the North Carolina Wetlands Restoration
Program (NCWRP). Please note it is the applicant's responsibility to contact the NCWRP at
(9,19) 733-5208 to idetermine availabil#ty and to request written approval of mitigation prior
to submittal of a PCN. For additional information regarding the application process for the
NCWRP, check the NCWRP website at http://h2o.enr.state.nc.us/wrp/ind_ex.htm. If use of
the NCWRP is proposed, please check the appropriate box on page three and provide the
following information:
Amount of stream mitigation requested (linear feet): NA
Amount of buffer mitigation requested (square feet):
Amount of Riparian wetland mitigation requested (acres):
Amount of Nop-riparian wetland n i igation requested (acres):
