Inspection Summary
A site visit was conducted by the Inspector to help with the development of an approvable O & M plan for dewatering the
pit There are two streams in the vicinity of this mine pit Discharges occunng to the north and northwest of the pit will
drain to a large wetland area that Is contiguous with a network of mosquito ditches, contiguous with Williston Creek
Williston Creek the network of mosquito ditches and the unnamed tributary (UT) to Williston Creek are all classified SA
HQW waters of the state and are functioning primary nursery areas (PNA) Determining a 7Q10 for the UT to Williston
Creek or the mosquito ditches is impossible without a boat or hip waders The permittee and his consultant (Mark
Eakes)proposed a discharge to the large wetland due west of the discharge location (see attached map), using a level
spreader This wetland had standing water in it the day of the site visit due to a recent large rain The wetland area takes
in a large area adjacent to Williston Creek and will be used to provide Infiltration The Division of Land Resources (DLR)
mining application for this mine pit (DLR #16-74) indicates no more than 95 000 gpd will be discharged from the pit if the
discharge exceeds 100 000 gpd a water use permit from the Division of Water Resources (DWR) Central Coastal Plain
Capacity Use Area Program will be required The permittee proposes 4 potential stormwater settling basins along the
west and south edge of the pit that could drain to UT's to Howland Creek (classified SA ORW HQW waters of the State)
Wastewater discharges from pit dewatering can not be discharged to Howland Creek due to it s ORW classification The
current O & M plan needs to reflect a pump rate equal to that specified In the DLR application All monitoring

Dear Mr Willis
Secretary
In accordance with your application for a discharge permit received on March 7, 2012,
we are forwarding herewith the subject certificate of coverage to discharge under the subject
state — NPDES general permit This permit is issued pursuant to the requirements of North
Carolina General Statute 143-215 1 and the Memorandum of Agreement between North Carolina
and the US Environmental Protection Agency dated October 15, 2007 (or as subsequently
amended)
Please take notice that this certificate of coverage is not transferable except after notice to
the Division of Water Quality The Division of Water Quality may require modification or
revocation and reissuance of the certificate of coverage
A requirement of this permit is compliance with the Division of Land Resources' (DLR)
Mining Permit, therefore, you must hold a approved DLR permit before any mining industrial
activities take place
This site will discharge to a wetland near a receiving stream designated as High
Quality Waters (HQW) and a Primai-3 Nur serf Area WNA), Williston Creek Shoald the
dewatering activities result in a discharge to Williston Creek, a flow limit will be imposed in
accordance with 15A NC AC 213 0224(l)(h)(v)
Please note that mine dewatering wastewater includes wet pit overflows caused solely
by direct rainfall and groundwater _seepage for this type of mining operation Any discharge of
this water (and any stormwater commingled with it) is subject to the effluent limitations in this
permit
This general permit allows the discharge of storrnovater and ceitatn types of vYastebvater

O&M Plan
This is to serve as the operations and maintenance plan for the CLD Pit of Robert Preston Willis, in
Williston N C , which is located in Carteret County
The type of discharge that will be present on this site will be mine dewatering Reference is made in the
site plan that illustrates the primary point of discharge and also secondary points of discharge from the
mine Robert Preston Willis proposes to dewater mining operations through the following sequence of
events
1 Erosion control items will be installed prior to any mining activities on the site Sediment basins,
road ditches, silt fencing, settling pools and levels spreaders will be properly installed per plan
design before mining activities begin in any area of site These items will also be properly
monitored and maintained on a weekly basis, or more frequently if needed
2 Excavation will begin in Pit area 1(indicated on map)in the north eastern most point of limit and
continuing south widening out both east and west as limits allow
3 When mining of course sand material extends below the static ground water elevation (37
inches below ground elevation) the water will be pumped into settling basin 1(136 feet by 45
feet being 6 foot in depth, with a settling volume capacity 24,480 cubic feet), with a overspill
dam (lined with fabric and class b stone) 2 feet below top of berm allowing elements to settle ahC? ,a d

Ref Sand Mine on Halltown Road _ W It,L k S p IT
Dear Mr Willis,
A site evaluation was conducted at your sand thine located off Halltown Road in this Jacksonville area of
Qnslow County The purpose of this evaluation was to determine the effect of the mine on the adjacent
wetlands
The wetland boundary was flagged in the field and has been surveyed by Parker and Associates A detailed
survey has also treat provided which shows the pit, wetlands and pit water elevation at the time of the
survey At this time the dewatering has not drained the wetlands This was apparent by the standing water,
saturation in first 12' of profile, wetland vegetation present, and the presence of hydric soils
Auger borings were dug around the edge of the pit adjacent to the wetlands and the water level in the mine.
Soils were found to be group Tito group IV soils depending on depth Hydraulic conductivity of the soils
was found to be 01 to I" per hour Ksat readings in the Bottom of the pit were found to be 1 to 3" per hour
This data was placed in The Skaggs Method Lateral Effect model to deummne the lateral effect of the mining
on the wetlands
Analysis #1 was calculated using a ksat of 1 3' per hour to a depth of 72 , and an assumed restrictive layer of
72" (restrictive layer known to be deeper than 50 ) The results of the model showed that a buffer of 86 6'
was needed before the mining activities would affect the wetlands The survey shows that the closest
distance to the wetlands from the pit is 117', which is well beyond the 86 6 At this time the rmning
operations have not dewatered the wetlands on the site
Ali permits will be issued by the state and are subject to ail rules of the county and state The Findings are
based on the conditions of the site at the time of evaluation and any alterations may adversely impact the
results
If you have any questions please feel free to contact meat 910-330-2784 Thank You
