Approval of 401 Water Quality Certification and Additional Conditions [MODIFICATION]
Dear Mr. Buchanan:
You have our approval, in accordance with the attached conditions and those listed below, to place fill
within or otherwise impact 0.75 acres of wetlands (temporary), 60 linear feet of perennial stream (40 ft
temporary and 20 ft permanent), and 175 linear feet of intermittent stream (temporary), as described in
your application dated September 16, 2009, and received by the Division of Water Quality (DWQ) on
September 21, 2009, with additional information from the original application received from you on
November 12, 2008, and November 14, 2008, to construct the proposed interceptor and pump station
elimination project at the site. After reviewing your application, we have decided that the impacts are
covered by: General Water Quality Certification Number 3699 (GC3699). General Certification 3699
allows you to use Nationwide Permit NW 12 when issued by the US Army Corps of Engineers (USACE).
This Certification replaces the Certification issued on November 14, 2008. 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:

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 and authorized by this
approval letter. 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. No Sediment and Erosion Control Measures in Wetlands and Waters
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.
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. 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. 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.
Construction Stormwater Permit NCGO 10000
Upon the approval of an Erosion and Sedimentation Control Plan issued by the Division of Land
Resources (DLR) or a DLR delegated local erosion and sedimentation control program, an
NPDES General stormwater permit (NCGO10000) administered by DWQ is automatically issued
to the project. This General Permit allows stormwater to be discharged during land disturbing
construction activities as stipulated by conditions in the permit. If your project is covered by this
permit [applicable to construction projects that disturb one (1) or more acres], full compliance
with permit conditions including the sedimentation control plan, self-monitoring, record keeping
and reporting requirements are required. A copy of this permit and monitoring report forms may
be found at hgg. //h2o. enr, state. nc. us/su/Forms_Documents. htm.
6. If concrete is used during the construction, then a dry work area should be maintained to prevent
direct contact 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/fish kills.
7. 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 GC 3699.
Sewer Systems
The project shall comply with 15A NCAC 2H.0219(i)(2)(G) and all other State, Federal and
local sewer system regulations.
9. Notification of Construction
The applicant and/or authorized agent shall contact the DWQ Express Review Program in writing
at the letterhead address within ten (10) days of the commencement of construction.
10. Certificate of Completion
Within thirty (30) days of the 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 Division of Water Quality, 1650 Mail Service Center, Raleigh,
NC, 27699-1650.
The applicant/permittee and their authorized agents shall conduct all activities in a manner consistent with
State water quality standards (including any requirements resulting from compliance with §303(d) of the
Clean Water Act), and any other appropriate requirements of State and Federal Law. If the Division
determines that such standards or laws are not being met, including failure to sustain a designated or
achieved use, or that State or Federal law is being violated, or that further conditions are necessary to
assure compliance, then the Division may reevaluate and modify this General Water Quality Certification.
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
the North Carolina General Statutes to the Office of Administrative Hearings, 6714 Mail Service Center,
Raleigh, NC, 27699-6714. This certification and its conditions are final and binding unless you ask for a
hearing.
This letter completes the review of the Division of Water Quality under Section 401 of the Clean Water
Act. If you have any questions, please telephone Lia Myott Gilleski or Joseph Gyamfi at 919-733-1786.
