Dear Mr. Parr:
I am writing to you on behalf of George C. Cowand,Jr. and your request for additional information regarding
the proposed modification of the Wildcat Road Mine, Permit #21-03, in Chowan County. Comments on your
request are listed below.
• Wetlands and streams-Blue-line stream and known wetland boundaries are now shown on the
revised mining map.
• East pond excavation and release-the request to release a portion of the currently permitted "East
Pond" is hereby rescinded. All acreage currently permitted will remain so, and new acreage will be
added under this proposed modification. The "East Pond" area will remain under permit until
remaining excavation and reclamation has been completed.
• Erosion and Sediment Control measures-all E&SC measures are shown on the revised mining map.
• Construction details-copies of E&SC measures construction details are provided with this letter or
shown on the revised mining map.
• Overflow pipe-existing stormwater overflow pipe is being added as an additional point source
discharge for Wildcat Road Mine through modification of owner's NCG020807 General Permit COC.
Copy of application is attached.
• NPDES Permit-the Wildcat Mine operator has decided to keep the NPDES permit active currently to
provide for possible future dewatering. Sampling and DMR reports will continue as before.
• Mine map preparer-inadvertently left off the original submission, now shown on the revised maps
submitted with this letter.
1Thank you, please letme know if you have further questions.

OPERATION AND MAINTENANCE PLAN(REVISED 2023)
SAND MINE DEWATERING AND WATER CONTROL STRUCTURE
Operator: George Clay Cowand,Jr.,221 Old Merry Hill Road, Merry Hill, NC 27957
Job Location: Wildcat Sand Mine,Wildcat Road(SR 1208), Edenton, NC 27932, Mining Permit#21-03,
NCG020807
County: Chowan County
Prepared by: Ken Elliott,consultant
Date: June 27,2023
This plan defines responsibilities for operating,inspecting,and maintaining equipment and structures
used for constructing and dewatering the Wildcat Sand Mine safely,and that dewatering will not
degrade or negatively impact any wetlands or waters of the state.
Description and Operation of the Wildcat Sand Mine&Dewatering Process:
Wildcat Sand Mine is an existing 9.0-acre sand mine excavation located 3 miles northwest of Edenton,
NC on high sandy land. The mine has been in operation for approximately 40 years with the last
modification being in 2011. The mine consists of an existing active 19.59-acre pond and a second
unused bonded 0.65-acre pond. Currently Mr.Cowand is filing an application with DLR to modify and
expand the excavation to a total of 24.80 acres with an affected acreage of 35.65 acres.
There is an existing 3.1-acre area of land adjacent to the northeast corner of the larger pond that was
semi-excavated in the early 1970's when Mr.Cowand's father removed topsoil down 2-3 feet. The area
was bermed during this excavation and was then allowed to grow up in trees and groundcover
afterward. The area at this time is completely covered by hardwood and pine, is 2-3 feet below natural
ground level,and still has the original 10ft x 4ft berms. Mr.Cowand would like to be allowed to de-
water his main pond occasionally and wants to use this wooded area to process the mine dewatering
wastewater. Dewatering the main pond will allow for full depth excavation and proper reclamation of
the edges of the pond. It is the intention of Mr.Cowand to only dewater the excavation as needed,
which will not entail full-time dewatering.
The outlet for the dewatering pump will be located on the southwest corner of the sediment pond,and
there will be an overflow outlet located on the northeast corner of the sediment pond. There is an
existing partial berm located in the middle of the sediment area separating it into two halves,which will
require overflow wastewater to travel the entire length of the sediment area before reaching the
overflow outlet. This will increase the dropping out of sediment from the mine wastewater before the
water reaches the overflow.
The discharge point will release clear water to a feeder woods ditch,leading to an blue-line irrigation
ditch draining to Pollock Swamp, Pembroke Creek,Edenton Bay and Albemarle Sound(see map for
discharge point locations).

Water will be pumped from the main pond to the sediment pond by a 12in gasoline-powered transfer
pump operating at idle speed. Estimated flow from the pump will be 667 gallons/min. Water will travel
30 feet through a buried 12in pipe to the southwest corner of the sediment pond. It is the intention of
Mr.Cowand to drop the water level in the main pond approximately 2 feet when needed,which is
anticipated to be only once or twice a year, not full time or year round. Irrigation of adjacent fields
(from groundwater) by neighboring farmers has kept the main pond at low levels during spring,summer
and early fall. Dewatering by Mr.Cowand is not necessary at those times.
The overflow from the sediment pond will be controlled by a water height control structure located 2
feet below the top lip of the sediment pond berm in the northeast corner of the area,and will consist of
a pair of 6in wide capped PVC pipes buried in the separation berm. One pipe will be 1ft above the
bottom of the sediment pond,and the second will be 2 feet above the bottom. This will allow
approximately 2 feet of freeboard below the top of the berm. This control structure will allow water to
flow through the buried 6in pipe into an existing 3ft wide woods ditch located adjacent to the northeast
berm of the sediment pond. The overflow water will exit the pipe through an outlet stabilized with a
20ft long riprap-lined apron in the ditch. The overflow water will then travel northward 75 feet where it
will join an existing 10ft wide irrigation ditch(blue-line)and flow from there into Pollock Swamp,
Pembroke Creek,and on into Albemarle Sound.
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 450 feet
through a pine and hardwood wooded area to reach the overflow point. That will give enough surface
area to allow sufficient sedimentation to occur. There will be a minimum 3ft tall berm around the
perimeter of the sediment pond to prevent offsite stormwater from entering the sediment area and
damaging sedimentation rates.
Sedimentation and Erosion Control
There is a 10ft wide irrigation canal(labeled blue-line on USGS maps)running along the northern edge
of the sediment area,separated from the area by an existing 4ft berm with groundcover and trees
established. There will be no direct overflow from the sediment area into this canal. Overflow point will
be on the north and east side of the sediment area,flowing into an existing 3ft wide feeder ditch that
leads 75 feet to the irrigation canal. Overflow into the feeder ditch will be stabilized by riprap installed
in the feeder ditch(see diagram)to prevent erosion of the ditch.
All erosion and sedimentation will remain inside of the permit area. During mining operations and
dewatering,the majority of the water leaving the excavation will remain inside of the permit area and
will only overflow occasionally. The sediment area is shallow,and there is a sand layer below the
bottom of the area. The porosity of the soil under the sediment pond will allow most of the water
pumped into the pond from dewatering to seep back into the ground naturally. Any excess water
overflowing from the sediment pond will flow downstream towards Pollock Swamp, located 0.5 miles
away, and then on to Pembroke Creek.

Maintaining the Water Height Control Structure,Settlement Pond,Ditches,and Irrigation System
Inspections and maintenance are required to obtain the intended function of safely dewatering the sand
mine,and to maintain the life of any adjacent wetlands or waters of the State. Items to inspect and
maintain during the 10 year life of the mine dewatering permit are:
• Inspect the water control structures regularly,especially following heavy rains and runoff,or
during periods of operation of the structure.
• Remove accumulated debris from the control structure inlet pipe.
• Inspect the structure for excessive settlement or seepage.
• Inspect all components of the structure, including appurtenances,and repair or replace any
damaged items as needed.
• Inspect embankments, berms and appurtenant structures,and repair as needed.
• Repair any damage to vegetated areas or berms with compacted earth fill,reshaping,sodding,
reseeding and mulching as needed.
• Inspect riprap outlet stabilization structures in ditches regularly, replace dislodged rock as
necessary.
• 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 Process and Effects of Dewatering
Analytical and qualitative monitoring of mine dewatering wastewater will be in accordance with the
NCG020807 permit,as follows:
• All ponds in the Wildcat Sand Mine permit area will be inspected daily by the operator to
identify any abnormal conditions.
• All berms and erosion control and sedimentation control structures will be inspected following
significant(1/2-inch) rainfall events for damages,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.
• Overflow of wastewater process will be inspected daily during periods of dewatering the
excavation.
• Outflow of dewatering wastewater will be monitored quarterly at the overflow exit stabilization
structure for pH,settleable solids,turbidity,and total flow. Samples will be collected and tested
onsite for pH,and the remainder will be tested for the remaining parameters by a North
Carolina certified lab.

• Rain gauge data will be collected by monitoring rain gauge data monthly and after each rain
event.
Records
Data will be collected as follows:
• Data will be collected from samples taken from the wastewater point source discharge in
operation at the time.
• Point source discharge data:data from the site taken quarterly,date&time,general weather
conditions, pH of sample,status of process at point source, inlet or outlet,other DWQ required
data.
• Visual monitoring of adjacent woodlands for potential dehydration during mining or dewatering
activities will take place weekly,photography of the woodland areas will be done as needed and
documented. 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 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 Wildcat Sand
Mine will not degrade or negatively impact any wetlands or waters of the State.
• The permittee shall obtain authorization from the Director of the NCDWQ prior to utilizing any
chemical flocculants at Wildcat Sand Mine.
2023 Addendum
2023 modification to NCG0202807(attached)is to add one stormwater overflow discharge point to the
permit that will allow safe discharge of stormwater during major rain events. Discharge point is a
permanent 8-inch pvc pipe located on the northwest excavation edge of the east pond. Pipe is buried
