Continuing Compliance:
11. Mr. Dan Danieley and Burlington-Alamance Airport Authority, 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. Dan Danieley and/or Burlington-
Alamance Airport Authority 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. Dan Danieley
and/or Burlington-Alamance Airport Authority 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;
Culverts:
12. Culvert Installation
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. Therefore, you must provide plans with adequate details that indicate that the current
stability of the stream will be maintained or enhanced. You must receive written approval from this
Office for the above plans before the culvert(s) is installed. Culvert(s) must be installed according to
approved plans.
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.
