On February 8, 2016, the Division of Energy, Mineral, and Land Resources received your NPDES
Name/Ownership Change Form requesting transfer of Certificate of Coverage (COC) No. NCG020699
General Stormwater/Wastewater Discharge Permit NCG020000.
Thank you for submitting the letter explaining the situation and Pump Operation and Monitoring Plan.
Unfortunately, we are unable to process your request to transfer this permit to Hardy Construction, Inc.
without more adequate documentation and because the previous owner/operator (W.O. White, LLC)
owed several years of unpaid annual fees. You must apply independently for coverage of discharges
from this operation. Enclosed is a copy of the Notice of Intent (NOI) application for coverage under
NCG020000.
Please bear in mind that operating a treatment facility, discharging wastewater, or discharging specific
types of stormwater to waters of the State without a valid NPDES permit will subject the responsible
party to a civil penalty of up to $25,000 per day. The return of this application does not affect the legal
requirements to obtain other permits which may be required by the Division of Energy, Mineral, and'Land

WTRODUCTION
This plan contains the pump operation and monitoring procedures for mine dewatering activities
associoted with the J.C. Holton Sand Pit operated by W,O. White, LLC, and located of 1 191 Broad
Creek Road, in Craven County.
PURPOSE
In order io facilitate "dry" mining techniques, water is removed from file active portion of the
excavation using a pump(s).
AQUIFER INFORMATION
According to the NCDENR, Division of Water Resources, Visual Hydrogeologic Fran-iework, North
Carolina Hydrogeological Database website, one hydrogeologic unit is present within the proposed
maximum depth of the mine site, the Surficial aquifer. The top of the Castle Hayne confining unit is
estimated to be 39 feet below the existing ground elevation, two reef deeper than the maximum
mine depth. This information is based upon the approximate center of the mine (lot 34.1 194N, long
76,9590W) and data recorded from NCDENR boreholes nearest the mine.
The NCDENR information reports an estimated ground surface elevation of 10 feet and the confining
unit depth reported above is corrected to reflect an existing ground elevation of 12 feet. A copy of
the visual hydrogeologic framework information is provided with this plan.
PIEZOMETER (MONITORING WELL) INFORMATION
PURPOSE
Piezometers are used to monitor the extent and effect of proposed mine dewatering activities on
subsurface water levels, and to establish a relationship between the depressed subsurface water
levels and any resulting effects on the adjoining properties.
No piezometers (monitoring wells) are currently proposed for the mine dewatering activity.
Adjoining property owners have expressed concern about potential impacts to the water level in
their pond caused by mine dewatering activities. To mitigate the effects of dewatering, an existing
pump will be replaced by a float controlled pump to maintain the desired water level in the
adjoiner's pond using wafer from the mine pit.
There are no known private water supply wells in the area of the mine site.
PROPOSED CONSTRUCTION
If required by any of the permitting agencies, piezomelers will be installed in the following manner
Loch plezometer shalt be constructed using a five foot minimum length of 2" diameier, .010 slotted,
PVC screen connected to the length of PVC well casing necessary to extend the tip of the screen to
a depth of least 10 feei below the existing subsurface water levels. The piezometer well casing
should extend at leasf one foot above the existing grade.

A fine sand pack shall be installed from the bottom of the well to one foot above the lop of the
screen. A two fool thick bentonite seal shall be placed directly over the sand pack. Native soils
removed during well excava lion may be used to fill the well to the existing ground elevation. A
concrete pad cr collar shall be constructed at tine existing grade and centered on each well casing
to secure the well pipe and provide a stable reference elevation for measuring the groundwater
elevation. A removable protective sleeve, cap, or cover shall be installed to prevent direct entry of
rainwater and to provide access for measuring the subsurface water level.
PUMP INFORMATION
The pump used at the mine site is a hydraulically coupled submersible pump with a maximum
capacity of approximately 2,000 gallons per minute. The pump engine is positioned on the bank of
the active mine pit, is hydraulically coupled to a float mounted, submersible pump located within
the pit. The pump is used to create a water surface elevation that is a maximum depth of 35 feel
below existing grade,
PUMP OPERATIONS
GENERAL
Pumping will be employed as groundwater is encountered, and the pump wilt be utilized as required
to maintain a water surface elevation that is slightly lower than the excavation aclivities to enable
the use of "dry" mining techniques.
Continuous use of the proposed pump(s) at the reported capacity will result in 2,900,D00 gallons of
water removed from the active excavalion pit per day.
Previous purnping activities at the mile site indicate that after the desired water surface elevation is
achieved, only 4 to 5 hours of pumping are typically required daily to maintain the desired level.
If is recommended that pumping activities be suspended whenever periods of inactivity al the mine
will last longer than the lime required to dewaler the active excavation.
ADJOINER'S POND
A separate, float -operated pump is being used at the mine siie to maintain the desired water level
in the adjoining subdivision's pond located to the east of the mine site. The pump is being provided
to mitigate the effects of mine pit dewatering on the adjoining pond while dewatering activities are
being employed.
EXISTING EXCAVATION
In order to limil the amount of sediment ccrried out of the mine excavation with mine water beirig
removed, mine purnp(s) shall, if possible, be operated during hours whert the excavators) are not
operating,
When possible, mine dewatering shall be performed in advance of and to a depth greater than
that of excavation activities to prevent the excavation activities from mixing soil particles with the
water to be removed.
The primary dewatering pump(s) shall be located as for front the excavation equipment and active
disturbance as possible.

Discharge from the dewatering pump(s) shall be directed into a water body formed in an inactive,
separate portion of the existing excavation in order to provide a sediment removal function. The
separation can be provided through soil dikes or floating filtration curtains.
When an inactive, separate portion of the existing excavation is no longer available or is not
removing sediment to the level required by issued permits, pumping shall be suspended until
additional sediment measures are installed,
Additional measures may include, among others, the installation of check dams within the existing
system of ditches, the use of a "dirt bag" filtration type device on the pump discharg6 line, the
installation of an NCDENR standard sediment basin, the use of NCDENR approved chemical
treatments, and/or other such device(s), individually or collectively, in order to provide the required
sediment removal.
PROPOSED EXCAVATION
The proposed excavation shall remain physically separated from the existing excavalion by leaving
an undisturbed soil dike between the two pits. Discharges from the pump(s) dewatering the
proposed excavation shall be directed in the west end of the completed existing excavation.
The completed existing excavation shall to
She function of a sediment basin during
dewatering of the proposed excavation. Water shall discharge from the east end of the completed
existing excavation through the proposed outlet structure. Check dams(s) shall be installed in the
existing system of ditches to ensure that a visible water level is maintained in the ditches bordering
the wetland area. A pump can be used to withdraw water from the completed existing excavation
and discharge it into the wetland area ditches as an alternative to installing check darns.
PUMP DISCHARGE
Water discharged from the pump travels through the inactive portion of the mine excavation to the
existing system of ditches and eventually leaves the area of the mine site near the southeasl corner
of the permit boundary. From this point, the existing ditches'flow eastward approximately 2,800 feet
toward Upper Broad Creek, a tributary of the Neuse River.
Upon approval of the December 2008 mining permit modification request, a discharge structure will
be installed in the south-east corner of the existing excavation to replace the existing discharge
point. Upon initiation of the proposed excavation, pump discharge will enter the western portion of
the completed existing excavation and discharge through the proposed structure.
MONITORING PLAN (PUMP)
Pump monitoring is required for the Central Coastal Plain Capacity Use Area Water Use Permit and
NPDES permit.
Monitoring shall include type and number of pumps operating, hours operated, volume withdrewn
(gallons per day), depth of pump intake (below existing ground), water surface elevation, and any
additional information requested by the permitting agency.
Monitoring shall be performed daily unless otherwise direcled/ollowed by the permitting agency.
During pumping, withdrawal rates shall be assumed to equal previously indicated pump capacity
unless actual measurements indicate otherwise,

Withdrawal rates shall be reported according to the requirements dictated by the applicable
permitting agency• -
Pump withdrawal rate records shall be retained for a period of at least 5 years from the date of
measurement, unless otherwise indicated by permitting agencies.
MONITORING PLAN (PIEZOMETERS)
No piezometers are currently proposed.
The permeable sands present in the mine apparently extend to and provide a hydrogeologic
connection to a pond in the adjoining subdivision. The pond is iocated 200-250 feet horizontally from
the easternmost portion of the mine and provides a similar function to a monitoring well.
If required by a permitting agency;
The monitoring wells shall be installed, allowed to stabilize, and existing subsurface water
elevations shall be recorded prior to changing the existing dewaiering practices•
Subsurface water elevations shall be measured relative to a constant datum, such as top of
the well casing,
Subsurface wafer elevations in the monitoring wells shall be recorded daily throughout the
initial mine water drawdown and until a balance is achieved between water withdrawal
activities and groundwater inflow.
After a dewaiering balance is achieved, subsurface water levels in the monitoring wells shall
continue to be recorded daily until no significant change is recorded. Water levels shall be
recorded weekly until no significant change is recorded for two consecutive weeks. Once
monitoring well levels achieve ibis level of stability, wafer level recording shall continue on a
monthly basis. Changes in recording frequency may be subject to permitting agency
approval. Permit requirements govern if they conflict with this monitoring schedule.
Any time that the dewaiering pump depth is increased to create a lower water level in the
excavation, then piezometer monitoring shall revers to daily monitoring, Monitoring
frequency can then be changed according to the plan indicated above.
Monitoring results shall be recorded and reported according to the requirements dictated
by the applicable permitting agency and shall be retained for a period of of least 5 years
from the date of measurement, unless otherwise indicated by permitting agency.

WETLANDS RECHARGE AND MONITORING
A delineation performed during April of 2009 identified an area of ju6sdictionat wetlands located
near the proposed mine extension and the existing lake. The delineation was performed by Misters
Paul Farley and Corey Novak of Land Management Group, Inc of Wilmington, NC and field verified
by Ms. Tracey Wheeler of the US Army Corps of Engineers. The identified wetland area is indicated
on the June 19, 2009 revision of the Modified Mine Plan. A fifty-feef wide undisiurbed buffer is also
indicated where the proposed mining activities and the wetland boundary are closest to each
other.
There is an existing ditch that marks the easternmost edge of the identified wetland area. to order
to offset any effect on the presence/supply of near -surface water within the wetland area during
the temporary dewatering of the excavation site, a portion of the water discharged frorn the mine
pump(s) wil! be diverted into the system of existing ditches that are adjacent to wetland area. A
nearly -full water level shall be maintained within the existing ditches, whether through the use of
check dams, sufficient pump discharge volumes, or similar methods a all times while an artificially
depressed water level is main#wined within the excavation.
Monitoring of the wetlands shall take the form of daily visual inspections of existing plants to ensure
that the vegetation appears to remain healthy, as is seasonally appropriate, and to observe ]hat
there is neither an apparent absence nor over -abundance of wafer within the wetland area as
compared with pre-dewatering conditions. As with any monitoring method, observations shall be
recorded to include day, lime, recent ,or current weather, observations, any findings that indicate a
change in water supply should be made and any subsequent changes made to the water, quantity
being supplied. The proposed monitoring method is subject to approval and/or modification by the
permitting agencies.
CONTINGENCY PLAN
In the event that the proposed mine dewatering has an adverse effect on any other offsite wafer
body or the wetland area adjoining the mine site, action sha]I be taken to counteract the effect.
The action taken shall be agreed upon by the owner of the effected water body, regulatory
agency (if applicable), and the mine operator.
MANDATORY PLAN REVISION
The approved pump operation plan shall be revised if additional withdrawal capacity is required, or
if it is determined that there are private water supply wells located in the vicinity of the mine and
dewaiering activities are adversely effecting their production, or if mine dewafering adversely
affects the nearby wetlands.
This plan is also subject to those revisions determined necessary by the permitting agencies.

Enclosures: { 1 j Partial Copy, August 6, 2009 Revision, Pump Operation and Monitar'Ing Plan for
W.O. White, LLC, J.C. Holton fit, prepared by Robert M. Chiles, PE
f2) Copy, Piezometei- Well Detail.
Dear Mr. Edgerton:
On behalf of our client, W.O, White, LLC, and in response to your letter of July 10, 2009, we provide
these enclosures for your review and'approvdl.
Enclosure 1 provides q copy of the revised written portion of the proposed pump operation and
monitoring plan for the Holton:Pit.. The revisions include additional measures.fo be taken to reduce the
volume of sediment carrioa;offsite by dewatering pump discharges Gild medsures intended to mainlain
the existing hydrology wifhln, the wetlands that are located next to the proposed mine expansion. The
revisions are contained primarily in the Pump Operations section and'fn the added Wetlands Recharge
and Monitoring section. the enclosed partial copy does not include fti&.USGS quadrangle, vicinity map,
road map, or mine maps, as these have not changed since our last submissions
I
Within the existing �.pxcavafion section of the plan, a number of possible measures are included, to
be implemented as needed, in order to achieve the sediment removal requirements of the issued
permits. The primary mechanlsrn for achieving sediment removal.during.fhe proposed excavation is to
use the water body farmed in.the coiyoleted existing excavation as a sedlmenf basin. With dewatering
pump discharges entering of the west end and leaving the east end of the comp)eled excavation, a
minimum straight-line flow path of approximately 1;70Q feet is provided as well as a length to width ratio
of approximately three to one.
The existing system of ditches onsite is connected to the ditch that forms the eastern border of the
delineated welland area. The primary means for preserving the existing hydrology within the wetlands is
to divert water from the pump discharges and maintain an approximately fuli water level in the existing
ditches adjacent to the wetlands. There has been no visible surface wafer.within the wetland area
during any site visit, and the invert of the existing ditch along the east edge was mostly dry also. While it is
possible fhat previous mining activities have already artificially lowered the water levels to some extent,
the intention is to maintain the current condiftons without artificially flooding the entire area.

The plan proposes to monitor the mining activity's affect by conducting daily visual inspections of
existing vegetation throughout the wetland area. Changes in the apparent health of plant life within the
wetland area wilt be the first indication of changes in the groundwater supply. The plan indicates a
construction method for piezomeier wells, but does not call for their implementation unless requested by
your agency. Enclosure 2 provides a typical piezorneter well detail from a previous WO_White project site
and gives a visual depiction of the description contained in the plan.
Should you require additional information or have ony questions, please contact us your
convenience.

Enclosures: (I } Drawing, Approximate Cone of Depression for J.C. Halton fit, N.C. Mining Permit 25-
14, prepared by Robert M. Chiles, PE
Bear Mr. Edgerton: -
On behalf o€ our client, W.O. Whife,:UC, we Wovide_ this response to your letter of September 24,
2009.
As we discussed during ourlast.telephone conversation, we have prepared a drawing to depict
the approximate groundwater.c(one of depressioh.that will be created by dewatering the proposed mine
expansion. The groundwater contours depicted in the drawing, provided as enclosure 1, are based upon
reverse distance-drawdown:ih€orr6ation geherated using -the NCDENR DWR software, The values for
transmissivily and storage -coefficient were generofed by.a distance-drawdown analysis based upon
observations made at the Holton Pit during various stages of water removal in the existing mine. The
contours assume an initial groundwater surface #ocated at elevation 4 (recent survey data) or
approximately 6 feet below the existing ground surface. Based upon the approximate cone of
depression, when the proposed mine •pit is dewatered to its maximum depth, the groundwater surface
underneath the wetland area will vary -from elevation 4 to elevation -5 feet,.indicating a maximum
change of approximately 9 feet. Wfie.n•added to only the into rp) 6-f lon about the mine dewalering's
effect on the adjacent property owner's_porfd, this -indicates that the proposed dewatering in the new
section of the mine will cause an unacceptdble effect on the hydrologic conditions within the wetland.
As you have access to the some information and angJ,ytical:iools,:this is probably the basis for the
statement in your letter that "it appears very, likely,tlIat thi ,de* Wotering activities have or wilt degrade
adjacenf wetlands."
On October 23, 2009 our office visited the site of the Holton Pit to further investigate the wetland
area that is adjacent to the proposed mine expansion. During our site visit, we performed a survey to
identify the elevations of the water surface in the existing pond on the Holton property and the ground
surface in the wetland area. Because the pond is isolated, and its water level is not dependant upon a
stream or other surface water feature, the water surface in the pond is presumed to closely indicate the
existing groundwater surface elevation. On the day of our site visit, our survey data indicated a water
surface elevation of 3.88 feet.
The wetland identified on the project site is a relatively flat area surrounded by raised features
that effectively create a shallow bowl. On the day of our site visit, our survey data indicated ground
surface elevations of 8.11 and 8.15 feet at two locations within the wetland area.

Owing to the difference between the apparent ground water surface elevation and the ground
elevation of the wetland, two soil borings were advanced in the wetland area. The ground elevations
Within the wetland correspond with the locations of the two soil borings and both are indicated on the
drawing provided as enclosure i .
Both soil borings were advanced to a depth of four feet below the exisfing ground surface using a
hand operated, three inch diameter, cylindrical auger. The soils within the two borings were examined at
six inch intervals and the findings are presented here as well as on the drawing. Aside from moisture
contained in the soil itself, free water was not encountered in either boring.
Depth Below Erisfing Ground Surface : Observations
0 to 12 inches : Organic soil, root mat (roots not oxidized), and leaf litter.
12 to 24 inches: Clayey sill or silty clay; with increasing clay content. Black fine sandy silty
clay,
24 to 36 inches: Black color changing to brown. Increasingly plastic clayey silt or silty clays.
i 36 to 42 inches; Bottom of clay, top of light grey/beige fine sandy silt.
42 to 48 inches: Sandy silt transitions to light tan tine sand, similar to mason's sand,
Observations made by myself and Mr. Paul. Falloy of Land Management Group, Inc who
performed the wetland delineation,.lead us to presume #hat the wetland area is dependant upon
rainfall, and not groundwater to maintain its hydrolody. _,This, presumption is supported by the 18 to 24 inch
thick clay layer underlying the wetlidnd and ttiejour feet of separation between the wetland ground
surface and the apparent groundwater surface.
Previous nine dewatering_activities in the existing excavation doweled the water level in the
adjoining land owner's pond,.and your letter references this information. It is important to note that the
adjoiner's pond had been'eXcavated to a depth where the pond bottom extended into the same layer
of cleap.sands th6i are being excavated by -the mining operation. The -porous nature of the sand layer
created a significant hydrologic connection between the pond and the excavation, as evidenced by
the impact on the pond's water level.
Based upon the presence of the we#land, the-4 feet of separation between the wetland surface
and the groundwater, and the,presence of the 18 to 24 inch thick clay layer, a similar hydrologic
connection does not exist between the.wetland and the propos'e_d mine excavafion. Your letter
recommended establishing a "restrictive horizon". -fa separate the dewatered aquifer from the wetland
area. We conclude that such a restrictive horizon -is already provided by the clay layer discovered by the
soil borings. _
With the knowledge of the underlying ii is our opinion that the proposed mine
devvatering will have no effect on the wetland area. Accordingly, we propose no changes to the
previously submitted pump operation and monitoring plan. The plan already contains provisions to
provide supplemental wafter to the wetland perimeter and to monitor its plant life. It is our opinion that "a
plan to reestablish the proper hydrology" of the wetland has become unnecessary in light of the new
information provided by the soil borings.
Should you require additional information or have any questions, please contact us your
convenience. In the absence of further requests from you, we will look forward to the issuance of the
requested permit.
Very truly yours,
-ROBERT M. CHILES, P.E..,
