Dear Mr. Bryan:
You have our approval for the impacts listed below for the purpose described in your application dated March 18,
2021 and received by the Division of Water Resources(Division)on March 18,2021,with additional information
received on April 5,2021. These impacts are covered by the attached Water Quality General Certification Number

sold,the new owner must be given a copy of this Certification and is responsible for complying with all conditions.
[15A NCAC 02H.0507(d)(2)].
If you are unable to comply with any of the conditions of the attached Water Quality General Certification or with
the additional conditions itemized below,you must notify the Asheville Regional Office within 24 hours(or the next
business day if a weekend or holiday)from the time the permittee becomes aware of the circumstances.
The permittee shall report to the Asheville Regional Office any noncompliance with,and/or any violation of,stream
or wetland standards [15A NCAC 02B .0200]including but not limited to sediment impacts to streams or wetlands.
Information shall be provided orally within 24 hours(or the next business day if a weekend or holiday)from the
time the permittee became aware of the non-compliance circumstances.
Condition(s)of Certification:
Project Specific Conditions
1. The NCDOT Division Environmental Officer or Environmental Assistant will conduct a pre-
construction meeting with all appropriate staff to ensure that the project supervisor and essential staff
understand the potential issues with stream and pipe alignment at the permitted site. NCDWR staff shall
be invited to the pre-construction meeting. [15A NCAC 02H.0506(b)(2)and(b)(3)]
General Conditions
1. Unless otherwise approved in this certification,placement of culverts and other structures in open waters
and streams shall 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
downstream of the above structures.The applicant is required to provide evidence that the equilibrium is
being maintained if requested in writing by NCDWR. If this condition is unable to be met due to
bedrock or other limiting features encountered during construction,please contact NCDWR for guidance
on how to proceed and to determine whether or not a permit modification will be required. [15A NCAC
02H.0506(b)(2)]
2. If concrete is used during construction,a dry work area shall be maintained to prevent direct contact
between curing concrete and stream water. Water that inadvertently contacts uncured concrete shall
not be discharged to surface waters due to the potential for elevated pH and possible aquatic life and
fish kills. [15A NCAC 02B.0200]
3. During the construction of the project,no staging of equipment of any kind is permitted in waters of
the U.S. or protected riparian buffers. [15A NCAC 02H.0506(b)(2)]
4. The dimension,pattern,and profile of the stream above and below the crossing shall not be modified.
Disturbed floodplains and streams shall be restored to natural geomorphic conditions. [15A NCAC
02H.0506(b)(2)]
5. The use of rip-rap above the Normal High Water Mark shall be minimized. Any rip-rap placed for
stream stabilization shall be placed in stream channels in such a manner that it does not impede aquatic
life passage. [15A NCAC 02H.0506(b)(2)]
6. The Permittee shall ensure that the final design drawings adhere to the permit and to the permit
drawings submitted for approval. [15A NCAC 02H.0507(c)and 15A NCAC 02H .0506(b)(2)and

excavation in flowing water. [15A NCAC 02H.0506(b)(3)and(c)(3)]

minimize sedimentation and reduce the introduction of other pollutants into the stream. [15A NCAC

9. All mechanized equipment operated near surface waters must be regularly inspected and maintained to
prevent contamination of stream waters from fuels, lubricants, hydraulic fluids, or other toxic materials.

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 NCDWR 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 NCDWR may reevaluate and modify this certification. [15A NCAC 02B.0200]

activities. Impacts to areas within the fencing are prohibited unless otherwise authorized by this
certification. [15A NCAC 02H.0501 and.0502]
16. The issuance of this certification does not exempt the Permittee from complying with any and all statutes,

project by the end of the growing season following completion of construction. [15A NCAC
02B.0506(b)(2)]
20. There shall be no excavation from,or waste disposal into,jurisdictional wetlands or waters associated with
this permit without appropriate modification. Should waste or borrow sites, or access roads to waste or
