To Whom It May Concern:
This NPDES NCG02 General Permit application is part of a request by Ms. Jamie Basnight
Hatchell, manager of HOM Development, LLC, PO Box 2405, Manteo, NC 27954, to modify her
existing mining permit #27-50 to expand the current permitted excavation from 13.09 acres to 22.74
acres and increase the total permitted acreage from 24.43 acres to 51.59 acres. The permit area is
located at 8528 Caratoke Highway, Harbinger, NC, in Currituck County, on property owned by GB
Investment Group, LLC, Jarvisburg, NC.
The proposed mining permit area is in a flat sandy well -drained area mined by HOM Development
since 2015. The existing excavation will be expanded on its southern edge to increase mining acreage.
The mine permit area will not present any problems regarding runoff to adjacent areas when all
proposed erosion and sediment control measures are in place, and all runoff will be directed internal
to the permit boundaries. The purpose of the excavation will be to serve as wildlife habitat and to
increase scenic value for the landowner.
The excavation area will be located geographically 0.50-mile from the nearest public highway and
will be accessible only by Lucinda Lane, a private paved access road owned by GB Investment Group.
In addition to a North Carolina Department of Transportation facility, there are four residences and
one commercial business which also have ingress and egress rights to Lucinda Lane.
During previous mining activities of the current permit, dewatermi g was permitted through an
NPDES Stormwater permit issued by NCDEQ DEMLR, permit #NCG020851. For this mining
permit modification, the operator also desires to modify the current permitted dewatering activities in
order to discharge at a different location. The operator is applying for a new NPDES Stormwater
perrnit from NCDEQ at this time.
Excavation activities will be screened from public view on all sides by existing full growth
woodland, vegetated sand berms, and distance across adjacent fields. There will be minimum 25-ft
wide unexcavated buffers on all sides of the permit area, and a minimum 25-ft wide visual screen of
existing woodland around the permit area. The active area of the mine site will be located a minimum
of 80 feet from wetlands located offsite.
Upon receipt of the approved permits from NCDEQ, HOM Development plans to excavate the
pond to an average depth of 25 feet below normal ground level and will include construction of
proper cut slopes on all sides of the excavated area as required by permit. Reclamation of the permit
area will include grading, leveling, and grassing of all affected areas. The permit is requested for an
8-year period.

-2-
April 23, 2020
All adjacent landowners have been contacted and made aware of the proposed excavation
operation, and land entry agreements have been obtained. The excavation area will be well marked
with warning and keep out signs to prevent inadvertent public access.
HOM Development, LLC does hereby request approval for this NPDES NCG02 General Permit
application and asks that it be expedited as soon as possible. Ms. Jamie Basnight Hatchell, manager
of HOM Development, LLC appreciates your consideration of this permit application.
Sincerely,
Ken Elliott

OPERATION AND MAINTENANCE PLAN
SAND MINE DEWATERING AND WATER LEVEL CONTROL STRUCTURE
Operator: HOM Development, LLC, 1002 Driftwood Drive, Manteo, NC 27954
Job Location: Wilbur Griggs Mine, 8528 Caratoke Highway, Harbinger, NC 27941
County: Currituck County
Prepared by: Ken Elliott, consulting
Date: April 23, 2020
This plan defines responsibilities for operating, inspecting, and maintaining equipment and structures
used for constructing and dewatering the Wilbur Griggs Mine safely, and that dewatering will not
degrade or negatively impact any wetlands or waters of the state.
Description and Operation of the Wilbur Griggs Mine:
The Wilbur Griggs Mine is an existing 13.2-acre sand mine excavation in a 24.43-acre permit area
located off Caratoke Highway, Harbinger, NC, in Currituck County. The operator, HOM Development,
LLC, Jamie Basnight Hatchell, manager, is requesting a permit modification to expand the excavation
acreage to 22.74 acres and the permit area to 51.59 acres. The operator is currently permitted to
dewater the excavation and discharge the dewatering wastewater through a single point of discharge
located on the east side of the permit area, permitted through NPDES General Permit # NCG020851.
The operator desires to apply for a new discharge permit in order to move the sedimentation pond and
single point discharge to a new location in the permit area. The previous dewatering activity was
discontinued in December 2017, and the sedimentation pond was dismantled and land reclaimed with
groundcover.
The permit area is on high sandy land and is currently a cultivated farm field owned by GB Investment
Group, LLC, Brad Griggs, manager. At this time HOM Development is applying for a mining permit with
the NCDEQ Division of Energy, Mineral and Land Resources to modify the mining permit and begin the
expansion operation in June 2020. HOM Development is also applying for a Use Permit from the
Currituck County Planning Department for modification and construction of this mine.
Sand Mine Dewatering:
It will be necessary to dewater the excavation as it is being excavated to allow the excavating equipment
to enter the excavated area and safely and efficiently remove the sand from the pond bottom. This will
allow for full depth excavation and proper reclamation of the edges of the pond. It is the intention of
HOM Development to only dewater the excavations as needed, which will not entail full-time
dewatering.
For excavation purposes, dewatering will occur roughly every 30 days which will allow excavating
equipment to remove approximately 150 loads of sand up to ground level where it will be stockpiled for
later use. When the stockpile is depleted from usage, the excavation area will again be dewatered, and
another quantity of sand will be excavated.

The operator plans to construct a 0.90-acre above -ground sedimentation pond located 30 feet south of
the main excavation area on the southwest side of the permit area. The 6-ft tall berm around the pond
will have exterior a 3:1 exterior slope with full groundcover installed, and interior 2:1 slopes. Excavation
of the main 22.74-acre pond will begin approximately 30 feet from the sediment pond. The edge of the
sediment pond and main excavation will be 75 feet from the nearest wetland swamp. Use of the
sediment pond will forcibly hydrate the nearby wetlands located west of the sediment pond and
excavation and will minimize dehydration of the swampy land.
The operator will install an 8-inch dewatering pump between the 2 ponds at the south end of the main
excavation. Discharge from the dewatering pump will enter the sediment pond on its east corner. A
half -pipe water height control device (see attached diagram) overflow point will be located at the west
corner of the sediment pond. The sediment pond's overflow water will discharge and flow through a
12-in pipe 1300 feet long which will then discharge the water into a wetland creek located at the west
end of the permit area. The discharge point will release clear water into a 20-foot-long riprap-protected
basin, which will then flow 3200 feet by existing creek and ditch to Albemarle Sound.
Water will be pumped from the main pond to the sediment pond by the Bin gasoline -powered transfer
pump operating at idle speed. Estimated maximum flow from the pump will be 30,000 gallons/hour,
operating 12 hours per day, 0.36 mgd. It Is the Intention of the operator to drop the water level in the
main pond approximately 20 - 25 feet below normal ground level as needed.
The overflow from the sediment pond will be controlled by a half -pipe flash board riser water height
control device constructed in the western corner of the sediment pond. This control structure will allow
water to flow through the baffle into a 1300ft long x 12" wide PVC pipe leading northwest along the
permit boundary to an existing 20-ft wide basin which then leads 3200 feet to Albemarle Sound. For
erosion control, the overflow water will exit the discharge pipe onto a 20ft long riprap-lined apron in the
basin.
Time and distance will allow all sedimentation to occur to acceptable levels before the overflow water
reaches outfall from the sediment pond and then by pipe to the waters of the State. Water will have to
travel a minimum of 300 feet in the sediment pond before reaching 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 the surrounding sediment pond berm.
Sedimentation and Erosion Control
There is wetland swamp north and west of the proposed excavation, located 75 feet from the
excavation edge, running parallel to the permit boundary. The operator will establish a 50-ft wide
undisturbed buffer (no disturbance of any kind) inside the permit boundary adjacent to the wetlands
boundary. This buffer will be maintained by the operator as grass and pine tree ground cover.

In addition, there will be a 25ft unexcavated buffer (may contain roadways, stockpiles, and sediment &
erosion control devices) around the entire excavation area, between the excavation and the
undisturbed buffer.
All erosion and sedimentation will remain inside of the permit area. The operator will construct and
maintain an 10ft wide x 2ft tall grass -covered sand berm around the perimeter of the current affected
area of the excavation during all phases of operation. During mining operations and dewatering, most
of the water leaving the excavation will remain inside of the permit area and will only overflow through
the sediment pond occasionally. The sediment pond will be approximately 5 feet deep, 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 3200 feet to Albemarle Sound.
Maintaining the Sediment Pond Overflow Control Structure, Settlement Pond and Ditches
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 anticipated 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 overflow control structure.
• 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
NCG020000 permit, as follows:
Excavation
• All ponds in the Wilbur Griggs 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 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.
• 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 at the
discharge point and tested onsite for pH, and the remainder will be tested for the remaining
parameters by a North Carolina certified laboratory.
• Rain gauge data will be collected by monitoring rain gauge data monthly and after each rain
event.
Adjacent Owners
• Two residences with three groundwater wells are located within 1500 feet of Wilbur Griggs
Mine proposed excavation edge.
• HOM Development, LLC will establish and maintain a $3000 performance bond with Currituck
Planning and Community Development Department for each of these wells in order to aid with
repairs to the wells for any damages due to dewatering activities at Wilbur Griggs Mine.
• During the previous permit period, HOM Development, LLC established a performance
guarantee to any home or business within 2000 feet of the mine, should any damage occur to
their groundwater wells due to dewatering activities at Wilbur Griggs Mine, then HOM
Development would bear the costs of repairs. HOM Development will maintain this
performance guarantee throughout the modified permit period.
• During the previous permit period, three active groundwater level monitoring wells and one
pond level measuring staff were established between the current mine excavation and the
closest adjacent owners. Groundwater levels have been measured monthly in these wells since
2012. HOM Development, LLC will continue measuring these levels during dewatering activities
in this new modified permit period until excavation ends and the permit area has been
reclaimed.
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 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.
• There is no impact to adjacent wetlands anticipated during this operation. Discharge of water
from the sediment pond will be directly into adjacent wetlands. Previous dewatering activities
caused no visual impact to any wetlands on the property.
• 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 Bayview
Sand Mine will not degrade or negatively impact any wetlands or waters of the State. BMP's will
include:
o Sediment pond outlet structure with flashboard riser located at edge of pond for ease of
maintenance.
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 Sediment pond outlet basin will have rock lining or riprap stone layer to prevent
erosion, scour or sloughing of embankment
• The permittee shall obtain authorization from the Director of the NCDEMLR and the Stormwater
Program chief prior to utilizing any chemical flocculants at Robert White Sand Mine.
