Subject: Approval of Individual 401 Water Quality Certification
Highway 73 Industrial Project
Dear Mr. Cunningham:
Attached hereto is a copy of Certification No. WQC004733 issued to Robinson Weeks Partners, dated April
1, 2022. 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 Water Quality Certification. If
you change your project,you must notify the Division and you may be required to submit a new
application package with the appropriate fee. If the property is 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)].
This Water Quality Certification does not relieve the permittee of the responsibility to obtain all other
required Federal,State, or Local approvals before proceeding with the project, including those required
by, but not limited to, Sediment and Erosion Control, Non-Discharge, Water Supply Watershed, and
Trout Buffer regulations.
This Water Quality Certification neither grants nor affirms any property right, license, or privilege in any
lands or waters, or any right of use in any waters. This Water Quality Certification does not authorize
any person to interfere with the riparian rights, littoral rights, or water use rights of any other person
and does not create any prescriptive right or any right of priority regarding any usage of water. This
Water Quality Certification shall not be interposed as a defense in any action respecting the
determination of riparian or littoral rights or other rights to water use. No consumptive user is deemed
by virtue of this Water Quality Certification to possess any prescriptive or other right of priority with
respect to any other consumptive user regardless of the quantity of the withdrawal or the date on which
the withdrawal was initiated or expanded.
Upon the presentation of proper credentials,the Division may inspect the property.
This Water Quality Certification shall expire on the same day as the expiration date of the corresponding
Section 404 Permit. The conditions shall remain in effect for the life of the project, regardless of the
expiration date of this Water Quality Certification.

Non-compliance with or violation of the conditions herein set forth may result in revocation of this
Water Quality Certification for the project and may also result in criminal and/or civil penalties.
If you are unable to comply with any of the conditions of this Water Quality Certification you must notify
the Mooresville 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 Mooresville 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.
This approval and its conditions are final and binding unless contested [G.S. 143-215.5]. Please be aware
that impacting waters without first applying for and securing the issuance of a 401 Water Quality
Certification violates Title 15A of the North Carolina Administrative Code (NCAC) 2H .0500. Title 15A
NCAC 2H .0500 requires certifications pursuant to Section 401 of the Clean Water Act whenever
construction or operation of facilities will result in a discharge into navigable waters, including wetlands,
as described in 33 Code of Federal Regulations (CFR) Part 323. It also states any person desiring
issuance of the State certification or coverage under a general certification required by Section 401 of
the Federal Water Pollution Control Act shall file with the Director of the North Carolina Division of
Water Quality. Pursuant to G.S. 143-215.6A,these violations and any future violations are subject to a
civil penalty assessment of up to a maximum of$25,000.00 per day for each violation.
This Certification 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.

4. Erosion control matting that incorporates plastic mesh and/or plastic twine shall not be used along
streambanks or within wetlands. Citation: 15A NCAC 02H.0506(b); 15A NCAC 02H.0507(c)
5. No waste, spoil, solids, or fill of any kind shall occur in wetlands or waters beyond the footprint of
the approved impacts (including temporary impacts). Citation: 15A NCAC 02H.0506; 15A NCAC 02H
.0507(c)
6. Culverts (temporary/permanent) shall be designed and installed in such a manner that the original
stream profiles are not altered and allow for aquatic life movement during low flows. The
dimension, pattern, and profile of the stream above and below a pipe or culvert shall not be
modified by widening the stream channel or by reducing the depth of the stream in connection with
the construction activity. The width, height, and gradient of a proposed culvert shall be such as to
pass the average historical low flow and spring flow without adversely altering flow velocity. If the
width of the culvert is wider than the stream channel,the culvert shall include multiple boxes/pipes,
baffles, benches and/or sills to maintain the natural width of the stream channel. If multiple
culverts/pipes/barrels are used, low flows shall be accommodated in one culvert/pipe and
additional culverts/pipes shall be installed such that they receive only flows above bankfull.
Placement of culverts and other structures in streams shall be below the elevation of the streambed
by one foot for all culverts with a diameter greater than 48 inches, and 20%of the culvert diameter
for culverts having a diameter less than or equal to 48 inches,to allow low flow passage of water
and aquatic life. If the culvert outlet is submerged within a pool or scour hole and designed to
provide for aquatic passage, then culvert burial into the streambed is not required.
For structures less than 72" in diameter/width, and topographic constraints indicate culvert slopes
of greater than 2.5%culvert burial is not required, provided that all alternative options for flattening
the slope have been investigated and aquatic life movement/connectivity has been provided when
possible (e.g. rock ladders, cross-vanes,sills, baffles etc.). Notification, including supporting
documentation to include a location map of the culvert, culvert profile drawings, and slope
calculations, shall be provided to DWR 30 calendar days prior to the installation of the culvert.
When bedrock is present in culvert locations, culvert burial is not required, provided that there is
sufficient documentation of the presence of bedrock. Notification, including supporting
documentation such as a location map of the culvert,geotechnical reports, photographs, etc. shall
be provided to DWR a minimum of 30 calendar days prior to the installation of the culvert. If
bedrock is discovered during construction,then DWR shall be notified by phone or email within 24
hours of discovery.
Installation of culverts in wetlands shall ensure continuity of water movement and be designed to
adequately accommodate high water or flood conditions. When roadways, causeways, or other fill
projects are constructed across FEMA-designated floodways or wetlands, openings such as culverts
or bridges shall be provided to maintain the natural hydrology of the system as well as prevent
constriction of the floodway that may result in destabilization of streams or wetlands.
The establishment of native woody vegetation and other soft stream bank stabilization techniques
shall be used where practicable instead of rip-rap or other bank hardening methods. Citation: 15A
NCAC 02H.0506(b);15A NCAC 02H.0507(c)
7. If concrete is used during construction,then all necessary measures shall be taken to prevent direct
contact between uncured or curing concrete and waters of the state. Water that inadvertently
contacts uncured concrete shall not be discharged to waters of the state. Citation: 15A
02H.0506(b); 15A NCAC 02H.0507(c);15A NCAC 028.0200; 15A NCAC 02E3.0231

8. All proposed and approved temporary (including fill/culverts/riprap) impacts shall be removed and
the impacted area(s) shall be returned to natural conditions within 60 calendar days after the
temporary impact is no longer necessary. The impacted areas shall be restored to original grade,
including each stream's original cross-sectional dimensions, planform pattern, and longitudinal bed
profile. All temporarily impacted sites shall be restored and stabilized with native vegetation and
allow to naturalize. Citation: 15A NCAC 02H.0506(b);15A NCAC 02H.0507(c)
9. Any rip-rap required for proper culvert placement, stream stabilization, or restoration areas shall be
restricted to the area approved within the application. Soft/natural stabilization shall be utilized to
the maximum extent practicable. All rip-rap shall be placed such that the original streambed
elevation and streambank contours are restored and maintained and shall consist of clean rock or
masonry material free of debris or toxic pollutants. Placement of rip-rap or other approved
materials shall not result in de-stabilization of the stream bed or banks upstream or downstream of
the area or be installed in a manner that precludes aquatic life passage. Citation: 15A NCAC
02H.0506(b); 15A NCAC 02H.0507(c)
10. All work in or adjacent to streams shall be conducted so that the flowing stream does not come in
contact with the disturbed area. Approved best management practices from the most current
version of the NC Sediment and Erosion Control Manual, or the NC Department of Transportation
Construction and Maintenance Activities Manual, such as sandbags, rock berms, cofferdams, and
other diversion structures shall be used to minimize excavation in flowing water. Citation: 15A
NCAC 02H.0506(b);15A NCAC 02H.0507(c);15A NCAC 028.0200
11. All mechanized equipment operated near surface waters shall be inspected and maintained regularly
to prevent contamination of surface waters from fuels, lubricants, hydraulic fluids, or other toxic
materials. Construction shall be staged in order to minimize the exposure of equipment to surface
waters to the maximum extent practicable. Fueling, lubrication, and general equipment maintenance
shall be performed in a manner to prevent,to the maximum extent practicable, contamination of
surface waters by fuels and oils. Citation: 15A NCAC 02H.0506(b);15A NCAC 02H.0507(c); 15A NCAC
026.0200;15A NCAC 028.0231
