Total Buffer Impact for Project: 85,298 square feet.
The project shall be constructed in accordance with your application dated received on October 11, 2021.
After reviewing your application, we have decided that these impacts are covered by General Water
Quality Certification Number 4135. This certification corresponds to the General Permit 20192350 issued
by the Corps of Engineers. This approval is also valid for the Randleman Lake Riparian Buffer Rules (15A
NCAC 213.0250). In addition, you should acquire any other federal, state or local permits before you
proceed with your project including(but not limited to)Sediment and Erosion Control, Non-Discharge and
Water Supply Watershed regulations. This approval will expire with the accompanying 404 permit.
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 down
stream of the above structures.The applicant is required to provide evidence that the equilibrium is being
maintained if requested in writing by the NCDWR. If this condition is unable to be met due to bedrock or
other limiting features encountered during construction, please contact the 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)]
This approval is for the purpose and design described in your application.The plans and specifications for
this project are incorporated by reference as part of this Authorization Certificate. If you change your
project, you must notify the Division and you may be required to submit a new application package. If
the property is sold, the new owner must be given a copy of this Authorization Certificate and is
responsible for complying with all conditions. 15A NCAC 02B .0611(b)(2). The permittee shall report any
noncompliance with the conditions of this Authorization Certificate and/or any violation of state regulated
riparian buffer rules (15A NCAC 02B .0250).

If you are unable to comply with any of the conditions below, you must notify Ryan Conchilla with the
Transportation Permitting Branch at Ryan.ConchillaOncdenr.gov within 24 hours (or the next business
day if a weekend or holiday)from the time the permittee becomes aware of the circumstances.
Special Conditions:
1. Richland Creek is class WS-IV; 303(d) waters of the State. Richland Creek is on the 303(d) list for
impaired use for aquatic life due to fecal coliform. The NCDWR is very concerned with sediment
and erosion impacts that could result from this project. The NCDWR recommends that the most
protective sediment and erosion control BMPs be implemented in accordance with Design
Standards in Sensitive Watersheds (15A NCAC 04B .0124) or comparable BMPs to reduce the risk
of further impairment to Richland Creek. Post-construction stormwater BMPs should be selected
and designed to the MEP,to reduce target POCs in the 303(d) list for the receiving waters.
Additional Conditions:
1. All stormwater runoff shall be directed as sheetflow through stream buffers at non-erosive
velocities, unless otherwise approved by this Certification. (15A NCAC 02B .0250)
2. All riparian buffers impacted by the placement of temporary fill or clearing activities shall be
restored to the preconstruction contours and revegetated. Maintained buffers shall be
permanently revegetated with non-woody species by the end of the growing season following
completion of construction. For this condition, maintained buffer areas are defined as areas
within the transportation corridor that will be subject to regular NCDOT maintenance activities
including mowing. The area with non-maintained buffers shall be permanently revegetated with
native woody species before the next growing season following completion of construction. (15A
NCAC 02B .0250)
3. Pursuant to 15A NCAC 213 .0250,sediment and erosion control devices shall not be placed in Zone
1 of any Randleman Water Supply Watershed Riparian Buffer without prior approval by
NCDWR. At this time, NCDWR has approved no sediment and erosion control devices in Zone 1,
outside of the approved project impacts, anywhere on this project. Moreover, sediment and
erosion control devices shall be allowed in Zone 2 of the buffers provided that Zone 1 is not
compromised, and that discharge is released as diffuse flow.
This approval and its conditions are final and binding unless contested. [G.S. 143-215.5]
This Authorization Certificate can be contested as provided in Chapter 150B of the North Carolina General
Statutes by filing a Petition for a Contested Case Hearing (Petition) with the North Carolina Office of
Administrative Hearings (OAH) within sixty(60) calendar days. Requirements for filing a Petition are set
forth in Chapter 150B of the North Carolina General Statutes and Title 26 of the North Carolina
Administrative Code. Additional information regarding requirements for filing a Petition and Petition
forms may be accessed at http://www.ncoah.com/or by calling the OAH Clerk's Office at(919)431-3000.
