Approval of 401 Water Quality Certification and Authorization Certificate per the Neuse River
Buffer Protection Rules (15A NCAC 2B.0233) with Additional Conditions
Dear Ms. Drake:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.02 acres of 404/wetland, and 2,248 square feet of Zone 1 Neuse River basin
protected riparian buffers and 2,647 square feet of Zone 2 Neuse River basin protected riparian buffers, as
described in your application dated February 9, 2010, and received by the Division of Water Quality
(DWQ) on March 17, 2010, with additional information received from you on March 25, 2010, to
construct the proposed force mains project at the site. After reviewing your application, we have decided
that the impacts are covered by General Water Quality Certification Number(s) 3699 (GC3699). The
Certification(s) allows you to use Nationwide Permit(s) NW 12 when issued by the US Army Corps of
Engineers (USACE). 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 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 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
certification and any additional conditions listed below.
The Additional Conditions of the Certification are:
1. Impacts Approved
The 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 are
approved including incidental impacts:

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 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 without prior
approval from the Division. If placement of sediment and erosion control devices in wetlands and
waters is unavoidable, design and placement of temporary erosion control measures shall not be
conducted in a manner that may result in dis-equilibrium of wetlands or stream beds or banks,
adjacent to or upstream and down stream of the above structures. All sediment and erosion control
devices shall be removed and the natural grade restored within two (2) months of the date that the
Division of Land Resources or locally delegated program has released the project;
5. 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;
Miti ag tion:
6. Compensatory Mitigation Using the Ecosystem Enhancement Program (EEP)
Mitigation must be provided for the proposed impacts as specified in the table below. We
understand that you have agreed to provide wetland mitigation for proposed wetland impacts and
wish to make a payment to the Wetlands Restoration Fund administered by the NC Ecosystem
Town of Cary
Page 3 of 4
March 6, 2010
Enhancement Program (EEP) to meet this mitigation requirement. This has been determined by
the DWQ to be a suitable method to meet the mitigation requirement and additional mitigation
commitment. Until the EEP receives and clears your check (made payable to: DENR -
Ecosystem Enhancement Program Office), no impacts specified in this Authorization Certificate
shall occur. The EEP should be contacted at [phone] if you have any questions
concerning payment into a restoration fund. You have 60 days from the date of this approval to
make this payment. For accounting purposes, this Authorization Certificate authorizes
payment into the Wetlands Restoration Fund to meet the following compensatory
mitigation requirement:
Type of Impact Compensatory Mitigation Required River and Sub-basin Number
Buffer Zone 1 4,938 (square feet) Neuse/03020201
7. Diffuse Flow
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). However, if diffuse flow as per 15A NCAC 02B.0233(5) is not
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 DWQ written
authorization.
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
