NORTH CAROLINA 401 WATER QUALITY CERTIFICATION
THIS CERTIFICATION is issued in conformity with the requirements of Section 401 Public Laws 92-
500 and 95-217 of the United States and subject to the North Carolina Division of Water Quality (DWQ)
Regulations in 15 NCAC 21-1, Section .0500 to Mr. Bob Jones of Sandler At Amberly, LLC to fill 0.212
acre of wetlands and 1,421 linear feet of stream channel, including 456 linear feet of perennial streams and
965 linear feet of intermittent streams, in the Cape Fear River Basin, associated with the construction of the
Sandler at Amberly residential and commercial development in Wake and Chatham Counties, North
Carolina, pursuant to an application filed on the 22nd day of March of 2006 with additional correspondence
received April 4, 2005, and a modification request received on March 12, 2007 and issued on August 13,
2007, and the most recent modification request dated June 4, 2009 and received by DWQ on June 8, 2009.
The application and supporting documentation provides adequate assurance that the proposed work will
not result in a violation of applicable Water Quality Standards and discharge guidelines. Therefore, the
State of North Carolina certifies that this activity will not violate the applicable portions of Sections 301,
302, 303, 306, 307 of PL 92-500 and PL 95-217 if conducted in accordance with the application, the
supporting documentation, and conditions hereinafter set forth.
This approval is only valid for the purpose and design submitted in the application materials and as
described in the Public Notice. If the project is changed, prior to notification a new application for a new
Certification is required. If the property is sold, the new owner must be given a copy of the Certification
and approval letter and is thereby responsible for complying with all conditions of this Certification. Any
new owner must notify the Division and request the Certification be issued in their name. Should wetland
or stream fill be requested in the future, additional compensatory mitigation may be required as described
in 15A NCAC 2H .0506 (h) (6) and (7). If any plan revisions from the approved site plan result in a

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. For borrow pit sites, the erosion and sediment control measures must be designed, installed,
operated, and maintained in accordance with the most recent version of the North Carolina
Surface Mining Manual.
d. The reclamation measures and implementation must comply with the reclamation in
accordance with the requirements of the Sedimentation Pollution Control Act.
3. 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 404/401 Permit Application. 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;
4. 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.
Continuing Compliance:
6. Mr. Bob Jones and Sandler at Amberly, LLC shall conduct construction activities in a manner
consistent with State water quality standards (including any requirements resulting from compliance
with section 303(d) of the Clean Water Act) and any other appropriate requirements of State law and
federal law. If the Division determines that such standards or laws are not being met (including the
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, the Division may reevaluate and modify this
Certification to include conditions appropriate to assure compliance with such standards and
requirements in accordance with 15A NCAC 2H.0507(d). Before modifying the Certification, the
Division shall notify Mr. Bob Jones and Sandler at Amberly, LLC and the US Army Corps of
Engineers, provide public notice in accordance with 15A NCAC 2H.0503 and provide opportunity for
public hearing in accordance with 15A NCAC 2H.0504. Any new or revised conditions shall be
provided to Mr. Bob Jones and Sandler at Amberly, LLC in writing, shall be provided to the United
States Army Corps of Engineers for reference in any Permit issued pursuant to Section 404 of the
Clean Water Act, and shall also become conditions of the 404 Permit for the project;

7. Contruction Stormwater Permit NCGO10000
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
http: //h2o. enr. state. nc. us/su/Forms Documents. htm.
Stormwater Management Plan Implementation Procedures (No Further Approval Needed)
• The approved SMP must be constructed and operational before any permanent building or
other structure is occupied at the site. If a development is phased, then the approved SMP for
each future phase must be constructed and operational before any permanent building or other
structure associated with that phase is occupied.
• The approved SMP as well as drainage patterns must be maintained in perpetuity.
• The SMP may not be modified without prior written authorization from the SMP approval
authority. If the SMP falls under another state stormwater program, then a copy of the
approval letter and the modified SMP must be submitted to the 401 Oversight/Express Unit
prior to the commencement of the modifications.
9. 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.nedot.orp,/doh/operations/BMP manual/download/BMP 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.
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 Applicant shall 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.
10. 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/Wetlands Unit, North Carolina Division of Water Quality, 1650
