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 2H, Section .0500 to Mr. Russell Overman and the Martin County Airport
Commission, to fill 1.5 acres of jurisdictional wetland, 95 linear feet of stream and 0.00 square feet of Zone
1 Tar-Pamlico River basin protected riparian buffer, and 0.00 square feet of Zone 2 Tar-Pamlico River
basin protected riparian buffer, associated with the construction of the Martin County Airport improvements
which is located 2 miles north of US 13/64, at the intersection of Airport Road and Everetts Road, west of
Williamston, Martin County, North Carolina, pursuant to an application filed on the 19th day of December
of 2007 (received by DWQ on December 18, 2007), and by Public Notice by the U.S. Army Corps of
Engineers issued on the 22nd day of May of 2008 (received by DWQ on May 22, 2008), with additional
information received on June 25, 2008.
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
change in stream or wetland impact or an increase in impervious surfaces, the DWQ shall be notified in
writing and a new application for 401 Certification may be required. For this approval to be valid,
compliance with the conditions listed below is required.
Conditions of Certification:
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 to
wetlands, streams, and/or buffers, are approved including incidental impacts:

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.
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 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. 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. Russell Overman and Martin County Airport Commission 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. Russell Overman and Martin
County Airport Commission, 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. Russell
Overman and Martin County Airport Commission 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;
Mitigation:
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 wish to make a payment to the Wetlands Restoration Fund administered by
the NC Ecosystem 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. Until
the EEP receives and clears your check (made payable to: DENR - Ecosystem Enhancement
Mr. Russell Overman and Martin County Airport Commission.
Page 4 of 6
June 26, 2008
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 calendar 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 Re uired River and Sub-basin Number
404/Wetland 1.5 (acres) Tar-Pamlico/03020103
7. 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 http://h2o.enr.state.nc.us/su/forms Documents. htm. -1
8. 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.org/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
Mr. Russell Overman and Martin County Airport Commission.
Page 5 of 6
June 26, 2008
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. 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.
11. Diffuse Flow
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 213 .0259 (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.
12. 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
Division of Water Quality, 1650 Mail Service Center, Raleigh, NC, 27699-1650.
Mr. Russell Overman and Martin County Airport Commission.
