PUMPING OPERATION AND MAINTENANCE PLAN
SAND MINE DEWATERING WITH SEDIMENTATION POND
Operator: I/OBX Disposal & Recycling, LLC, Henry Carlton Spruill, Manager, 73 Waterfront Rd.,
Columbia, NC 27925
Job Location: I/OBX Sand Mine, Woodley Road, Columbia, NC 27925
County: Tyrrell County
Prepared by: Ken Elliott, consulting
Date: November 6, 2021
This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures
used for dewatering the I/OBX Sand Mine safely, and that dewatering will not degrade or negatively
impact any wetlands or waters of the state.
Description and Current State of the I/OBX Sand Mine Site and Mining Application:
The I/OBX Sand Mine is a proposed 15.41-acre sand mine excavation to be operated by I/OBX Disposal &
Recycling, LLC, Carl Spruill, owner & operator, in a 34.95-acre permit area located 2.2 miles southwest of
Columbia, NC on Woodley Road in Tyrrell County. The permit area is on cultivated, sandy land at 3-ft
elevation, owned by Thomas W. Spruill (applicant's uncle), located adjacent to a canal/tributary of the
Scuppernong River.
At this time Mr. Spruill is applying for a mining permit with the NCDEQ Division of Energy, Mineral and
Land Resources to construct the sand mine and begin operation in December 2021 or January 2022. An
NPDES General Permit application for dewatering is being submitted to NCDEQ, registration for water
usage has been submitted to the Division of Water Resources, and a Stormwater Pollution Prevention
Plan is in process of development.
Sand Mine Dewatering:
It will be necessary to dewater the pond as it is being excavated to allow excavating equipment to enter
the area safely and efficiently remove the sand from the pond bottom. This will allow for full permitted
depth of excavation of the pond and proper reclamation of the edges of the pond. It is the intention of
the operator to only dewater the excavation as needed, which will not entail full-time dewatering.
For excavation purposes, dewatering will occur intermittently three to four times per year. The
operator plans to excavate approximately 25,000 cubic yards of sand at a time while dewatering and
stockpile it for later usage. Once the stockpiled sand is depleted, the operator will dewater the
excavation again and remove another quantity of sand.
Mine dewatering wastewater will be treated before release to the Waters of the State. Use of a
sedimentation pond separate from the excavated mine is a traditional and effective means to remove
sediment from wastewater generated during mine dewatering operations.

Sedimentation Pond Construction and overflow Discharge:
The operator plans to construct a 0.92-acre above -ground sedimentation pond located 55 feet west of
the main excavation area. The aboveground pond will have 6-ft tall berms around the pond with 3:1
exterior slopes and full groundcover, and interior 2:1 slopes. The pond berms will have a minimum 1.5
feet of freeboard between the water surface and the top of the sediment pond bank. The sediment
pond will be located between the proposed mine site field and a 40-ft wide groundwater leveling canal
into which the sediment pond will overflow during dewatering activity. This canal is regulated for water
height by the Tyrrell County Water Management Committee and is part of the Riders Creek/Travis
Special Use Water Management District. This SUWMD designated primary "C" canal is directly
connected to Scuppernong River located 1500 feet south. In addition, there is a secondary "C" channel
located 1200 feet north of the sediment pond outlet that discharges into the primary "C" canal, and
another located 1400 feet south. Water height in the primary "C" canal is kept naturally full by its direct
connection with Scuppernong River, and the secondary "C" channels are kept artificially low by pumps
and dams regulated by Tyrrell SUWMD.
Sediment pond water level will be controlled by a half -pipe flash -board water height control device
installed in the south corner of the sediment pond berm. This control structure will allow water to flow
across the flash boards into a 25ft long x 15" wide buried PVC discharge pipe running westward through
the berm 20 feet to a discharge outlet on the shoreline of the groundwater levelling canal leading 1500
feet to Scuppernong River (C; Sw). From there, discharge water will flow 9 miles through the
Scuppernong River (C; Sw; SC) to Albemarle Sound (SB).
Dewatering Procedure:
The operator will install a 6-inch dewatering pump between the main excavation and sediment pond at
the southwest end of the excavation. Discharge from the dewatering pump will enter the sediment
pond on its north end, and there will be a constructed half -pipe flash board water height control device
(see attached diagram) discharge point located on the south end of the sediment pond. The discharge
point will release clear water through the water -height control device into the primary "C canal which
will drain to Scuppernong River.
Water will be pumped from the excavated pond to the sediment pond by the 6-in gasoline -powered
transfer pump operating at idle speed, approximately 1100 rpm. Estimated maximum flow from the
pump will be 8,000 gallons/hour, operating 12 hours per day, 0.096-mgd. It is the intention of Mr.
Spruill to drop the water level in the excavation approximately 20 - 25 feet below normal ground level as
needed.
Time and distance will allow all sedimentation to occur to acceptable levels before the overflow water
reaches outfall and then the waters of the State. Water will have to travel a minimum of 325 feet to
reach the overflow point which will give enough surface area to allow sufficient sedimentation to occur.
There will be a minimum 1.5 feet of freeboard between the water surface in the sediment pond and the
top of the sediment pond bank. Stormwater drainage will be unable to enter the sediment area and
damage the sediment pond rates, due to the height of a surrounding 2-ft tall sediment pond berm.

Wetlands Protection:
Removing water from the excavation using an aboveground sedimentation pond with overflow is a valid
dewatering method for this size pond. The excavation can be dewatered quickly, and water removed
from the excavation will be used to uniformly hydrate adjacent wetlands.
Once dewatered, excavation activity will be focused on removing sand as quickly as possible in order to
shorten the periods of dewatering. This will allow groundwater level in the pond to return to normal as
soon as possible to lessen possible impacts to adjacent wetlands, once dewatering ceases.
Groundwater Control:
Groundwater levels are not expected to impact areas outside of the immediate excavated dewatering
area. Groundwater levels are expected to remain stable despite dewatering of the excavation. The
excavation site is surrounded on three sides by canals kept naturally full by direct drainage connection
to Scuppernong River.
Groundwater level depletion is not expected to affect any neighboring groundwater wells. The closest
residence to excavation is located 2250 feet from the proposed excavation. The area is served by Tyrrell
County Water System.
Sedimentation and Erosion Control:
The operator will maintain a 30-ft wide unexcavated buffer and 60-ft wide undisturbed buffer on the
north, south and east sides of excavation activity and a 40-ft wide unexcavated buffer on the west side.
All erosion and sedimentation will remain inside the permit area. The operator will construct and
maintain an 8-ft wide x 2-ft tall grass -covered sand berm around the perimeter of the current affected
area of the excavation during all phases of operation, inside the unexcavated buffer. Stormwater falling
inside the active mining area will be directed to drain into the excavation.
Maintaining the Dewatering Equipment and Erosion Control Measures:
Inspections and maintenance are required to obtain the intended function of safely dewatering the sand
mine, and to maintain the life of any nearby wetlands or waters of the State. Items to inspect and
maintain during the anticipated 10-year life of the mine dewatering permit are:
• inspect embankments, berms and appurtenant structures, and repair as needed.
• Monitor overflow ditches for damage or stoppage from beaver activity, repair as needed.
• Repair any damage to vegetated areas or berms with compacted earth fill, reshaping, sodding,
reseeding, and mulching as needed.
• Promptly repair all leaks in delivery facilities by replacing valves, fittings, gaskets, and worn or
damaged parts.
• Maintain all screens, filters, valves, timers, and other electrical and mechanical equipment in
good operating condition, following manufacturer's recommendations

Monitoring the Dewatering Process and Effects of Dewatering:
Analytical and qualitative monitoring of mine dewatering wastewater will be in accordance with the
NCG020000 permit, as follows:
• I/OBX Sand Mine will discharge mine dewatering wastewater into Scuppernong River, classified
as C;Sw. Discharge water will be analyzed quarterly per requirements of their NPDES permit.
• Discharge water will be sampled and analyzed for pH, Total Suspended Solids (TSS), turbidity,
salinity, and Enterococcus bacteria. Samples with benchmark exceedances will require the
operator to increase sampling, per NPDES permit, until sample results are cleared.
• All excavated ponds in the I/OBX Sand Mine permit area will be inspected daily by the operator
to identify any abnormal conditions.
• All berms and erosion control structures will be inspected for damages monthly and within 24
hours after every storm event greater than 1.5 inches, and all structures will be repaired
immediately.
• Special inspections will be conducted immediately following severe storms, vandalism, and
other significant events.
• Dewatering process will be inspected daily during periods of dewatering the excavation.
• Rain gauge data will be collected by monitoring local rain gauge data monthly and after each
rain event.
Wetlands Monitoring:
Wetlands are located northward and southward of the proposed I/OBX Sand Mine site. Level 1
wetlands landscape assessment by US Fish & Wildlife Service indicate one type of wetlands on the
Spruill parcel:
• Semi -permanently flooded, Palustrine scrub/shrub deciduously forested wetlands.
Level 2 wetlands assessment has not been performed on the site, due to presence of permanently
flooded groundwater lowering ditches connected to flooded "C" channels between the excavation area
and adjacent wetlands. Flooded ditches will serve as hydration devices to help maintain normal
groundwater levels. Operator will monitor drainage ditches weekly to ensure presence of water in the
ditch at all times.
Records
Data will be collected as follows:
• Visual monitoring of adjacent wetlands and farmland for potential dehydration during mining or
dewatering activities will take place weekly. Solutions to any degradation caused by any mining
activity will include alteration of dewatering process. DWQ will be consulted as needed;
alterations to process will be recorded.

• Elliott Consulting will maintain the following records in a permanent file at the Elliott Consulting
office at PO Box 112, 202 Elliott Road, Aydlett, NC 27916: a record of all significant actions
taken; as -built drawings; permits; analytical results from sampling; and related material. Copies
of all inspections, monitoring reports and lab analyses shall be provided to NCDWQ on a regular
basis and as requested.
BMP Conditions
• The permittee will utilize best management practices to ensure that dewatering the I/OBX Sand
Mine will not degrade or negatively impact any wetlands or waters of the State. BMP's will
include:
o All berms and erosion control and sedimentation control structures will be inspected for
damages monthly and within 24 hours after every storm event greater than 1.5 inches,
and all structures will be repaired immediately.
o Temporary gravel construction entrance will be maintained at foot of mine access road
at intersection with Woodley Road.
o Operator will maintain riprap outfail protection on the overflow drainage ditch
downstream of sediment pond.
o Groundcover will be established on all sections of the permit area when not in use by
mining activities.
