Dear Mr. Furr:
Attached hereto is a copy of Certification No. WQC004754 issued to Andrew Furr and Hilltop
Management, LLC, dated April 5, 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.
Upon the presentation of proper credentials, the Division may inspect the property.

14. Culverts 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. lithe 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.

19. Any rip -rap required for proper culvert placement, stream stabilization, or restoration of temporarily
disturbed areas shall be restricted to the area directly impacted by the approved construction
activity. 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)
20. 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
