Inspection Summary:
This inspection was conducted per request from Jacob Sinclair for analytical monitoring relief at inactive outfalls.
During this inspection we discussed a possible outfall that will be created as a result of breaching the dam in the Neisler
Mine. We determined that this outfall does not need to be added to the stormwater monitoring plan, however, please visually
inspect this area following storm events for 30 days after breaching the dam to monitor stabilization of the breached area.
The sediment basin at the Wylie Mine may be removed and outfall 4 may be omitted.
Please continue to establish vegetation on inactive areas and slopes in accordance with site permits.
If you have any questions, please contact our office at 704-663-1699.

Subject: General Permit No. NCG020000
Kings Mountain Minerals, Inc. -
Moss Plant
COC NCG020089
Cleveland County
In accordance with your request for renewal of a discharge permit received on July 11, 2014, 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 Energy, Mineral, and Land Resources. The Division may require modification or revocation and
reissuance of the certificate of coverage (COC).
Please be advised that EPA Region 4 staff who performed a Compliance Sampling Inspection (CSI) at
the end of March 2015 and follow-up sampling in June 2015 at other industrial mineral mines in North
Carolina raised concerns about metals levels in the discharges. The Stormwater Permitting Program
identified mines like this one that have similar activities. During the term of this General Permit, this site may
be evaluated further for an alternative permitting action, such as applying to the Division of Water Resources
(DWR) for an individual NPDES discharge permit (or modification of its existing wastewater individual permit)
prior to the expiration of this General Permit in 2020.
This permit does not affect the legal requirements to obtain other permits which may be required by the
Division of Energy, Mineral, and Land Resources, or permits required by the Division of Water Resources
(DWR), Coastal Area Management Act, or any other federal or local governmental permit that may be
required. If the conditions as stipulated in the COC are unacceptable to you, you may apply sooner for an
individual NPDES discharge permit.

Envi=menml Activities) Division of Energy, Mineral, and Land Resources
Quality
Technical Bulletin for NCG020000 (Mining) Last Revised 1018f2015
What activities are covered by this general permit?
NCG020000 coverage authorizes:
• Stormwater discharges associated with mining and quarrying of non-metallic minerals (except fuels),
mine excavation, processing, and vehicle maintenance activities (VMA) at mine sites.
• Wastewater discharges (dewatering, process wastewater, wastewater recycle system overflows).
• Operation of wastewater treatment systems (Authorization to Construct no longer required).
NCG020000 coverage Is NOT APPLICABLE to:
• Borrow Pits covered by the NC DOT statewide stormwater permit.
• Peat mining, coal mining, metal mining, or oil & gas extraction operations.
• Wastewater not specifically identified by the general permit.
What are key stormwater requirements?
NCG020000 requires periodic discharge monitoring and a Stormwater Pollution Prevention Plan (SPPP):
• Develop and implement an SPPP, and update it at least annually.
• Inspect Stormwater Best Management Practices (BMPs) once every seven (7) calendar days.
• Semi-annual analytical monitoring and qualitative (visual) monito_ ring.
• Report stormwater monitoring data once a year by March 1 st to DEQ Central Office.
• Report benchmark exceedances or Tier 2 monitoring jo the DEMLR Regional Office within 30 days.
• Respond to benchmark exceedances according to Tier response requirements.
What are key wastewater requirements?
NCG020000 stipulates wastewater treatment facility operational requirements and periodic discharge
monitoring:
• Notify DEQ if facility fails to perform satisfactorily or creates nuisance conditions.
• Only DEQ-evaluated flocculants may be used, if administered according to maximum application doses.
• Quarterly analytical monitoring for first year, or until four consecutive samples comply with all limits (then
semi-annual monitoring allowed). Quarterly monitoring schedule resumes upon any limit violation.
• Settleable solids (SS) monitoring applies to discharges to HQW, ORW, SA, SB, PNA, or Tr designated waters.
• Total Suspended Solids (TSS) limits specific to industrial sand mines, and to any mine discharging to HQW.
• Report wastewater effluent monitoring data once a year (by March i st) to DEQ Central Office.
• Report effluent limitation violations to the DEMLR Regional Office within 30 days.
• Effluent turbidity levels above the water quality standard prompt upstream and downstream monitoring.
What has changed from the previous permit?
Some changes specific to Stormwater:
• Reduced BMP inspections (weekly) for active
mines; additional allowances for inactive mines
that qualify for "dormant status."
• Changes to SPPP Annual Update.
• "Measureable storm event" (any size that results in
a discharge) replaces "Representative" event.
• New benchmarks and Tiers specific to turbidity.
• Total Flow and event duration no longer required.
• pH removed from VMA monitoring.
Some changes specific to Wastewater:
• May drop to semi-annual WW monitoring after four
quarterly samples that comply with all limitations.
• Turbidity instream monitoring is required if effluent
levels above the water quality standard.
• SS monitoring for sensitive waters only fHQW, etc.)
• TSS limits apply to industrial sand mines and HQWs.
Changes from the last permit are detailed in the
"Response to Comments and Summary of Changes"
Document for the 2015 NCG02 GP on our website.

PAGE TECHNICAL allLLETIN FOR N.C. GENERAL NPDES PERMIT NCGO20000 (MINING ACTIVITIES)
Frequently Asked Questions
What if my mine is inactive?
The permit makes allowances for
Inactive mines that have sus-
pended all industrial activities
and that certify to DEMLR that
the site has been stabilized. 1f
approved for "dormant status,"
these operations qualify for re-
duced BMP inspections and may
be exempted from outfall moni-
toring by the Regional Engineer.
Do I have to monitor all
outfalis?
Yes. However, you may request
Representative Outfall Status
(ROS). If approved, ROS allows
monitoring at fewer outfalls. To
request ROS, submit an ROS Re-
quest Form to the DEMLR Region-
al Office. The form is available
on our website (below).
Also, the Regional Office may
exempt mines with "dormant sta-
tus" from analytical and/or quali-
tative monitoring.
What if I sell my business, or
the name changes?
You are required to notify DEMLR
of those changes in writing, and
continuation of permit coverage
is subject to the Director's ap-
proval. Please submit the Name/
Ownership Change form located
on our Program website.
What do I do when my permit
expires?
Permitees are not required to sub-
mit an application for renewal un-
less directed by the Division. The
permiteee should continue to
abide by this general permit if it
expires and renewed coverage
has not yet been issued.
What is wastewater, and what
is stormwater at a mine site?
Any water contacting an actively
mined area, water used to pro-
cess mined materials, and mine
dewatering water are all consid-
ered "wastewater." For some
mines, "mine dewatering" also
means wet pit overflows, and not
just pumped -out water. Any
stormwater that commingles with
these waters is "wastewater."
"stormwater" includes runoff from
areas related to mining, pro-
cessing, or raw material storage
areas, such as haul roads or pro-
cessing plant areas at the mine.
Sometimes the answer is not clear
because of how broad the defini-
tions are. For example, N.C. con-
siders runoff from areas that con-
taih overburden only (no mined
or processed material), and that
does not comminclle with
wastewater {including runoff from
the mine), to be stormwater. If
you are unsure about discharges,
please contact the DEMLR Re-
gional Office for assistance.
Does a certified lab need to
analyze my samples?
Monitoring under NPDES permits
must be conducted in accord-
ance with test procedures ap-
proved in federal regulations in 40
CFR § 136. All labs certified by
LAST REV. 1018/15
North Carolina perform analysis in
accordance with those proce-
dures: While N.C. certification re-
quirements do not apply to testing
stormwater-only discharges, data
gathered under an NPDES permit
must still conform to federal re-
auirements. Using a North Caroli-
na certified lob is one way to en-
sure compliance. A list of certified
labs is available from: httpJ/
portal.ncdenr.org/web/wq/lab/
cert/
What if I pull samples for my
analytical monitoring, and I'm
unable to get a sample or valid
results for a parameter?
If this happens, please sample for
the missing parameter during the
next measureable storm event or
wastewater discharge.
If I sample my discharge, do I
have to do visual monitoring at
the same time?
You may, but it is not necessary
under NCG02. Some other gen-
eral permits require it, however.
What if there is no flow for a
period between two samples
that exceed a benchmark? Are
those consecutive exceedances?
Yes. This scenario still puts you in
Tier 2. The new permit is more
clear about how the Ter 2 trigger
omits periods of no discharge.
Who can help me with questions?

can be addressed to the DEMLR Offices:

Qualitative monitoring requirements vary. Most permits require qualitative monitoring to be
performed during a "representative storm event" or during a "measureable storm event." However,
some permits do not have this requirement. Please refer to these definitions, if applicable.
A "representative storm event" is a storm event that measures greater than 0.1 inches of rainfall
and that is preceded by at least 72 hours (3 days) in which no storm event measuring greater than
0.1 inches has occurred. A single storm event may contain up to 10 consecutive hours of no
precipitation.
A "measurable storm event" is a storm event that results in an actual discharge from the
permitted site outfall. The previous measurable storm event must have been at least 72 hours
prior. The 72-hour storm interval does not apply if the permittee is able to document that a shorter
interval is representative for local storm events during the sampling period, and the permittee
obtains approval from the local DWQ Regional Office.

Dear Ms. Jones:
DIVISION 01. 1iY
FEB
MOORESVILLE REGIONAL OFFICE
FEB 0 9 2011
W^sawnr
In response to the above referenced letter related to a revised targeted monitoring approach, and the
on site meeting of 31 January 2011 with Samar Bou-Ghazale and Andrew Pitner of the NCDENR,
Kings Mountain Minerals, Inc. (KMM), would like to submit the following responses to your
comments:
1. _A Descrintion of Well Construction: installation, diameter, depth, design, screen intervals,
construction records, maintenance plan and other relevant information.
KMM will provide a document entitled "Monitoring Well Installation Field Activity
Summary Report" which includes the well designations, well depths, well diameters, screen
lengths, depth of water, location map, lithologic logs and graphic completion logs. As part of
its well maintenance program, KMM will maintain the wells to assure depth to groundwater is
accessible and measurable during the operation of the H1 mine area. The wells are capped
and locked, and no pumps are installed in any of the wells. KMM will also ensure visual
signs are present to prevent damage to the wells.
2. Cross -Sectional Measurements and Visual Inspection of Stream: Cross -sectional
dimensions and measurements are required in order to provide hydrological information as
[nine de -watering and site modification occur. Please submit a plan to provide the
following:

a. On Stream "A", at points 1, 2 and 3 as shown on the submitted "Jurisdictional
waters and Groundwater Contour Map", and at a 4tn point of the permittee's
choosing, visually inspect, measure, dimension and photograph a cross sectional
profrle of the stream. Provide the depth at bottom and sides, as well as a drawn
cross sectional profile at each of these 4 points.
b. The above -described cross -sections and measurements/dimensions/inspections shall
be repeatably provided to DWQ on the following schedule (at minimum):
i. Initially after the permit is issued (within 60 days from receipt of the permit)
ii. Yearly until de -watering occurs.
iii. After de -watering is initiated:
1. For the First year after de -watering is initiated: on a quarterly basis.
2. For the Second and Third years after de -watering is initiated: on a
yearly basis.
3. Thereafter as the DWQ Mooresville Regional Office Staff direct.
4. The permittee may request a modification of this schedule after the
first year after de -watering takes place. Modification requests shall be
directed to the DWQ Mooresville Regional Office Staff in writing.
It is the opinion of KMM and its consultants that any waters present and flowing within
Stream "A" are solely related to stormwater impacting the 57-acre basin on the property that
drains into this Stream. Flow, when evident, is typically associated with significant storm
events. It is also our opinion that this intermittent, unimportant Stream is not fed by
groundwater. This feature is badly eroded due to the historic agricultural activities at the
property and may be a machine -created ditch by a previous owner, similar to the other
drainage features on the property. The entire length (original flags 1-15) is typically dry
during site inspections, even the day after rain�events, and is packed with abed of dead leaves
indicating rare water flow.
Storm flows from the 25-year storm event for this drainage area will generate 191 cfs of flow
in the Stream at the property boundary. Outflow from the planned Sediment Basin 1 (SB-1)
will only generate 0.59 cfs. of flow through the skimmer under normal operating conditions
and up to 3.43 cfs during a 10-year storm event and overflow into the riser. Once sediment
and erosion control. measures are in place, the majority of all stormwater that now flows into
the Stream, will be diverted and managed by SB-1. The dramatic decrease in storm flow
surge will greatly reduce / eliminate the erosive forces that are currently eroding the banks of
the Stream during storm events. Flow from the SB-I outlet will flow across a riprap outlet
dissipater and through a 50' vegetated buffer, which will diffuse the flow even more. The
flow will enter the stream near flag 2, which is located 30' upstream of the property line at
flag 1. Velocity calculations, referenced below, demonstrate that flow from SB-1 w411 not
exceed the self -scouring velocity and will not generate erosive flow. Cross sections along,the
stream are unnecessary to determine stream bank stability given the reduced volumes of storm
flow expected after construction of SB-1, the intermittent rainfall generated flow within the
stream; the referenced velocity calculations and the existing badly eroded gully conditions
that have been created by historic land uses.

There are two existing ground water monitoring wells on either side of this stream
(2010141073M and 2010H1072M). Groundwater at well 2010H1073M is 22 feet below the
ground surface (884.84') and the well is within 180' of the stream. Groundwater is 25 feet
below the ground surface at well 2010H 1072M (876.27') which is 350' from the stream. The
stream bed elevation of over half of the Iength (flags I -10) of the stream is at or below the
groundwater level elevation (884.84') within well 201OHI073M. The elevation of the
streambed from flags I through 10 increases gradually from 880.26" at flag I to 884.80' at
flag 10. The groundwater elevation at the stream is actually deeper than the adjacent wells but
does not contribute to stream flow. The stream bed is dry even though groundwater is above
the stream bed elevation for more than half it's length in the nearby well, indicating that
groundwater is not flowing underground to seep through the banks of the gullied stream and
does not contribute to stream flow.
1. KMM has corrected and is attaching for replacement in the application, Drawing 4
"Jurisdictional Waters and Groundwater Control Map". This revised map accurately depicts
the groundwater surface based on the depth to groundwater measured in the monitoring wells.
2. KMM is enclosing a report entitled "Velocity Calculations for the Stormwater Discharge
from -the Erosion and Sediment Control Pond (SB-1) and Determining the Impact of Pond
DischargeVelocity on the Jurisdictional Waters at H 1 Site". This analysis demonstrates that
even at 10-year storm event flows through both the skimmer and riser. in SB-1, that the flow
off the rip rap apron and into the channel near the property' boundary would not exceed the
self scouring velocity. The re -direction of storm flow from the Stream into SB-1 will reduce
the occasional erosional impact of significant storm events and moderate the flow into the
Stream near the property boundary well -below flow levels that would, initiate erosion.
KMM and its consultants: agree that there is no evidence that flow during a.10-year storm
event from SB-1 would increase the potential for erosion in the Stream and there is
overwhelming evidence that the design of the site stormwater diversion system and SB-I will
be responsible for moderating the impact of storm event flow and significantly reduce the
potential for erosion in the Stream.
• KMM will establish a baseline location between Stream stations 1 and 2, and document
the channel at this location between the outfall of SR-1 and the property boundary with
control staffs and photographic images. Field monitoring and documentation will occur
on an annual basis.
3. Well Monitoring Protocol. DWQ requests further information about your well monitoring
protocol. Please provide the following:
a. DWQ requires that you monitor the existing wells nearest Stream "A" — labeled
"2010H1073M" and "2010H1072M" shown on the submitted "Jurisdictional waters
and Groundwater Contour Map". These two wells shall be monitored monthly, at
minimum, and an annual data monitoring report shall be constructed and kept on
site.
b. Additionally, DWQ requests the permittee contruct one well near Stream "A"
,outside the buffer area and approximately 30 feet below the discharge from the

pond. This well should be shallow and should intersect the groundwater table. It
should have at least a 10- foot screen interval. As the permittee will need to establish
a base line before the initiation of the mining operation and of de -watering, provide a
monitoring protocol to this end. After de -watering commences, monitoring of this
well shall occur at least on a monthly basis. Provide a detailed site plan Staff as to
the exact location of this well to the DWQ Mooresville Regional Office within 60 days
of the receipt of the permit.
c. Provide an explanation.of how monitoring data will be analyzed to determine the
groundwater hydrology is removed or being maintained. if monitoring results
indicate impacts to any surface water, explain how these impacts may be abated.
Explain how data will be analyzed to determine or demonstrate the effects of
pumping and dewatering, and propose pumping regimes necessary to reduce
impacts if necessary. More extensive pumping test data should be included if
necessary. This strategy will be reviewed and may be modified by DWQ Regional
Office Staff. This shall be provided within 3 months of receipt of the permit.
KMM and its consultants agree that there is no evidence to indicate that there is contribution
from groundwater to surface water flow within the Stream. Stream flow is soley related to
stormwater events. The groundwater monitoring wells on the property were installed to
determine groundwater levels across the property for mine planning purposes and to
determine.potential groundwater impact at the property boundaries. Pumping of mine water
will likely produce hydrologic responses during the development of the mine, which is typical
for most mining operations. Mining on this site will be conducted on a campaign basis
several times per year and will not advance more the 10-20 feet vertically on an annual basis.
As a result of this mining campaign strategy, significant or rapid changes to groundwater
levels are not expected.
Based upon conversations and input from the COE and our consultants, KMM is re-
evaluating the Stream "A" characterization defined in the report entitled, "Wetland and
Stream Delineation for H-1 Site, Kings Mountain Site (90 acres), by Soil & Environmental
Consultants dated July 23, 2010. KMM does not now believe that this report accurately
characterizes the Stream based on additional outside input. KMM is working with their
consultants, the Army Corp of Engineers and the State DWQ to re -assess and reclassify the
Stream from an intermittent / perennial stream from stations 1-15 to a:classification of an
intermittent stream from stations 1-12. KMM has confirmed through preliminary analysis
with the COE and the DWQ, that jurisdiction does not extend upstream beyond station 12.
This work is ongoing and documentation will be provided when the work is complete. KMM
does not believe that this work is critical for this response nor the current permit application
as additional monitoring well data will document the conditions and the Stream area is not
planned for disturbance at this time.
Currently there are eight (8) monitoring wells on the proposed mine site identified as
2010H 1067M, 2010H [068M, 2010H 1069M, 201OH 1070M, 2010H 1071 M, 201 OH 1072M,
2010H 1073M and 201 OH 1074M. The monitoring wells were installed to monitor the
groundwater hydrologic response to the proposed mine dewatering activities within the
property boundaries. Initial monitoring well measurements demonstrated that groundwater
table ranges from approximately 38 to 21 feet below ground surface with the deeper depths to

groundwater appearing at the higher surface elevations. KMM and its consultants do not
believe that additional wells are necessary to monitor impact to groundwater within the limits
of the mine property based on the ranges and contouring produced in the initial sampling. As
the proposed mining plan has the end excavation at 120 feet below ground surface, it is
anticipated that there will be some groundwater hydrologic response, which is typical of any
mining operation. requiring dewatering.
Monitoring the two existing wells previously described on a monthly basis and adding a third
well within 20' of the stream bank are not necessary to determine if mine dewatering is
affecting flow within the surface water regime, because groundwater is not contributing to
surface flow. As previously presented, the intermittent flow in the Stream is generated from
storm events. KMM does not believe that there will be a de-watering;impact on the surface
water related to groundwater elevation changes. Flow within the stream will continue to be
intermittent in nature and will continue to be a function of storm events as it is currently.
In response to discussions on site with DWQ staff, KMM will agree to add an additional
monitoring well outside the Stream "A" buffer zone, between the SB-1 discharge and the
property boundary as suggested by Mr. Pitner of the NCDENR. KMM agrees that this is
a Demonstration Well for research purposes to understand the interaction of SB-1 waters
and groundwater near Station 1. No regulatory standards will be placed on this well, but
two baseline measurements will be completed prior to de -watering into SB-l. After de -
watering starts, groundwater depth measurements will be collected from this additional
well as part of the ongoing monitoring well program at the newly proposed H 1 mine.
e KMM will monitor each of its monitoring wells•on a semi-annual basis for depth to
groundwater measurement targeting a wet season and dry season monitoring event.
• KMM will analyze and contour the results of each round of groundwater monitoring and
keep that information along with the monitoring data at the main office located at 1469 S.
Battleground Avenue, Kings Mountain for mining operations inspections.
4. Provide assurance that the above data shall be kept on site and provided during mining
operation inspections.
• KMM will collect and maintain data generated as part of monitoring at the main office
located at 1469 S. Battleground Avenue, Kings Mountain and it will be available for
mining operations inspections.

Velocity on the Jurisdictional Waters at H1 Site

Dear Mr. Manning:
On behalf of Kings Mountain Minerals, Inc. (KMM), CP Engineering and Environmental Solutions
(CPEES) is submitting a response to the comment from Ms. Jenifer Jones of NC DENR- Division of
Water Quality - "Flow rates to streams to ensure flow rates will not overwhelm stream {cause
erosion, stream path, destroy benthic life etc" listed in her email dated November 03, 2010. We are
also responding to her request for a plan for "Cross -Sectional Measurements and Visual Inspection of
Stream" in her letter to Peter Flynn dated January 7, 2011.
This study addresses these concerns and presents results which show that the velocity calculated in
the jurisdictional water channel for the stormwater discharge from the Erosion and Sediment Control
Pond (SB-1) for both 10 and 25yr storm events was below the self scouring velocity (5 feet per
second (fps) published in the NC DENR Erosion and Sediment Control Planning Design Manual
Table 8.05a (Attachment C, C-1). Therefore, we conclude that the stormwater discharge from the
SB-1 would not impact/overwhelm (cause erosion, change in stream path, destroy benthic life) the
jurisdictional water channel at the H 1 site. As a result of this, we submit that the "cross -sectional
J measurements and visual inspection of stream" requirements would therefore not be necessary since
we have shown that the stream would not be impacted negatively by the discharge from S13-1.

To prove that there will not be any erosion in the jurisdictional water channel, CPEES has performed
velocity calculations in the channel for the I Oyr and 25yr stormwater discharges from the pond and
compared these calculated velocities to the self scouring velocities (The velocity of water which is
necessary to dislodge stranded solids from the stream bed), 5 fps, published in the NC DENR Erosion
and Sediment Control Planning Design Manual Table 8.05a (Attachment C. C-1). This self scouring
velocity figure is useful for steam bed gradients up to 10%. The stream gradients measured in this
study were 4.5% in the jurisdictional water channel and 8.69% in the small feeder channel located
just below the rock apron (Attachment A, A-19 & A-23).
The purpose of this comparison is to determine if there would be any erosion in the channel from the
pond discharges. Please note, if the calculated velocity in the channel is more than the self scouring
velocity, the channel would experience erosion and if the calculated velocity in the channel is less
than the se If scouring velocity, then the channel will have no impact from the proposed pond
discharges. Self scouring velocity in a channel is defined as the velocity of water that would dislodge
soil particles in the channel (bottoms and sides) and would keep them in suspension as long as the
velocity in the channel maintains or exceeds the self scouring velocity value
The following sections will explain the background information on the jurisdictional water channel,
the velocity calculations for the pond discharge going into the channel and our conclusions.
Stormwater and the Jurisdictional Water Channel Background at H1 Site
Based on our observations at the site, it appears that the stormwater from the major portion of the H 1 site
flows to the on -site unimportant jurisdictional water channel during the storm event. Therefore, we
believe that the channel (stream/waterway) must have experienced a 2-yr, 5-yr, i O-yr and possibly a 25-
or even a 50-yr storm event in the past 50 to 100 years and thus, may have shaped the waterway based on
the respective past flow conditions. During the mining activities, KMM will eventually direct the
majority of their stormwater flow into the mining pit area and thus, control the flow going into the SB-1.
Therefore, we estimate that the water released from SB-I would be lower than what the stream would
have already experienced in the past.
In addition, based on the photos submitted to the State in our earlier letter dated December 1, 2010, it is
very clear from the pictures that the channel and the area around the channel were observed to have well
grown trees, grass and small bushes and thus, expected to reduce the velocity of pond discharge going
into the channel and the subsequent flow in the channel. These trees, bushes and foliage growth will
retard the flow velocity and thus, reduce the erosion in the channel. Based on our drawings
(Comprehensive Site Map and Buffer Map) provided to the State in our permit modification package, 50
foot undisturbed buffer was assigned on all sides of the jurisdictional water channel as stipulated in the
permit modification package. Therefore, no ground clearing/disturbance in the 50 foot buffer is planned
at this time for the length of the mining activity. Thus, the trees, bushes, and the foliage will remain "as
is" on the ground and would help reduce the velocity of flow going into the channel from the SB-1 pond.
VelocitV Calculations for Stormwater Pond SB-1 Discharge into the Jurisdictional Water
Based on the NC DENR — Division of Land Quality Regulations, the sediment pond (SB-1) was
designed to manage the 1 Oyr storm event. The discharge from the pond would be released via a
2

skimmer and a raiser from the pond (refer to Erosion and Sediment Control Plans submitted to the
State in the mining permit modification package for details). An emergency spillway was designed
to allow stormwater discharge from the 25yr storm event should it occur (refer to Erosion and
Sediment Control Plans submitted to the State in the mining permit modification package for details).
Based on the drainage area and the pond routing calculations for a 10 yr-24 hr storm event
(Attachment A, A-4), the peak flow, 3.48 cubic feet per second (cfs), occurs at 17.96 hours
(Attachment A, A-2, A-13). The peak flow was used in the velocity calculations presented in this
report. In addition, CPEES has also evaluated the impact of stormwater discharge from the pond for
the 25yr storm event (Attachment A, A-14) on the channel erosion. The recently surveyed map
(Jurisdictional Waters Map submitted to the State) was used to obtain the cross sections and the depth
of the channel at various locations in the channel. Of the peak flow for the I Oyr storm event, the
pond releases approximately 0.6 cfs via the skimmer and 2.88 cfs via the riser (Attachment A, A-2,
A-13).
Two cross sections evaluated for the velocity calculations in this study are (Attachment A, A-16, A-
18, A-22):
1. Immediately after the pond pipe outlet apron (Attachment A, A-22)
2. In the jurisdictional water channel at the property boundary (Attachment A, A-18)
CPEES believes that these selected two areas would represent a typical condition for any erosion to
occur in the channel for the pond discharges. In addition, the flow conditions evaluated for each
cross section are:
1. The flow from the skimmer —a normal day today mine water pumping operation, 0.6 cfs
(Attachment A, A-2, A-13)
2. The combined flow from the skimmer and the riser for the 1 Oyr and the 25yr storm events
(Attachment A, A-2, A-13 and A-14).
Based on the velocity calculations for each situation, the calculated velocity (Attachment A, A-19
through A-21 and A23 through A-25) in the selected channel was found to be below the self scouring
velocity, 5 fps, (NC DENR Erosion and Sediment Control Planning Design Manual Table 8.05a.
Attachment C, C-1) for all the cases evaluated in this study. Therefore, in our opinion, the discharge
from SB- I will not overwhelm the channel in terms of erosion in the channel and loss of benthic life.
The calculations and the necessary supporting documentation are attached with this letter report. The
following table presents the velocity values for all the scenarios studied in this report.

Conclusions
Based on the velocity calculations in the channel for the I Oyr and the 25yr stormwater discharges
from the pond, it is evident from the study that the velocities in the channels were below the self
scouring velocity and therefore, we believe that the pond discharge will have NO impact on the
jurisdictional water channel in terms of stream erosion and loss of benthic life. Therefore, CPEES
and KMM respectfully request the State to rescind the stream channel cross-section monitoring
requirement in the permit approval process.

SUMMARY
The runoff from the 10 year storm event, 168.99 cfs (base on the rational method with a
time of concentration of 5 minutes) and 0.0619 efs (40,000 gpd from pump) for a total of
169.05 cfs was routed through the sediment basin using HydroCAD. An equivalent 10-
year 24 hour storm was used with a runoff of 170.44 cfs. The routing shows that a peak
flow of 3.48 cfs occurs at 17.96 hours. This flow (3.48 cfs) was used in determining the
velocity in the downstrearn channel.

1. Hose can be attached to outlet using the threaded 5" nipple. Typical methods used: on a
metal structure a steel stubout welded on the side at the bottom with a 5" threaded coupling or
reducers; on a concrete structure with a hole or orifice at the bottom, use a steel plate with a
hole and coupling welded to it that will fit over the hole in the concrete and bolted to the
structure with sealant.
2. Dimensions are approximate, not intended as plans for construction.
3. Barrel (solid, not foam core pipe) should be 1.4 times the depth of water with a minimum
length of 8' so the inlet can be pulled to the side for maintenance. If more than 12' long weight
may have to be added to inlet to counter the increased buoyancy.
4. Inlet tapers down from 6" maximum inlet to a 5" barrel and hose. Barrel is smaller to reduce
buoyancy and tendency to lift inlet but is sufficient for flow through inlet because of slope. The
inlet orifice can be reduced using the plug and cutter provided to control the outflow rate.
5. Inlet is 10" pipe between the straps with slots cut in the inlet and aluminum screen door
(smaller than shown in illustration) for access to the 6" inlet and orifice inside.
6. Capacity 51,840 cubic feet per day maximum with 6" inlet and 5" head. Inlet can be reduced
by installing a smaller orifice using the plug and cutter provided to adjust flow rate for the
particular basin volume and drawdown time required.
7. Shipped assembled. User glues inlet extension and barrel, installs vent, cuts orifice in plug
and attaches to outlet pipe or structure. Includes flexible hose, rope, orifice cutter, etc.

Determining the Skimmer Size
and the Required Orifice
for the
Fair loth Skimmer®S u rfa ce Drain
November 2007
Important note: The orifice sizing chart in the Pennsylvania Erosion
Control Manual and reproduced in the North Carolina Design Manual
DOES NOT APPLY to our skimmers. It will give the wrong size orifice
and not specify which size skimmer is required. Please use the
information below to choose the size skimmer required for the basin
volume provided and determine the orifice size required for the drawdown
time, typically 4-7 days in Pennsylvania and 3 days in North Carolina.
The size of a Faircloth Skimmer®, for example a 4" skimmer, refers to the maximum diameter of
the skimmer inlet. The inlet on each of the 8 sizes offered can be reduced to adjust the flow rate
by cutting a hole or orifice in a plug using an adjustable cutter (both supplied).
Determining the skimmer size needed and the orifice for that skimmer required to drain the
sediment basin's volume in the required time involves two steps: First, determining the size
skimmer required based on the volume to be drained and the number of days to drain it; and
Second, calculate the orifice size to adjust the flow rate and "customize" the skimmer for the
r. basin's volume. The second step is not always necessary if the flow rate for the skimmer with
the inlet wide open equals or is close to the flow rate required for the basin volume and the
drawdown time.
Both the skimmer size and the required orifice radius for the skimmer should be shown for each
basin on the erosion and sediment control plan. Make it clear that the dimension is either the
radius or the diameter. It is also helpful to give the basin volume in case there are questions.
During the skimmer installation the required orifice can be cut in the plastic plug using the
supplied adjustable cutter and installed in the skimmer using the instructions provided.
The plan review and enforcement authority may require the calculations showing that the
skimmer used can drain the basin in the required time.
Determining the Skimmer Size
Step 1. Below are approximate skimmer maximum flow capacities based on typical draw .
down requirements, which can vary between States and jurisdictions and watersheds. If one 6"
skimmer does not provide enough capacity, multiple skimmers can be used to drain the basin.
For drawdown times not shown, multiply the 24-hour figure by the number of days required.
Example: A basin's volume is 29,600 cubic feet and it must be drained in 3 days. A 3" skimmer
with the inlet wide open will work perfectly. (Actually, the chart below gives 29,322 cubic feet but
this is well within the accuracy of the calculations and the basin's constructed volume.)
Example: A basin's volume is 39,000 cubic feet and it must be drained in 3 days. The 3"
skimmer is too small; a 4" skimmer has enough capacity but it is too large, so the inlet will need
November 6, 2007 1 A- I

to be reduced using step 2 to adjust the flow rate for the basin's volume. (It needs a 3.2"
diameter orifice.)

below) for the same size skimmer chosen in the first step and the same number of days. This
calculation will give the area of the required orifice. Then calculate the orifice radius using Area
= zr r2 and solving for r, r = (Area/3.14) .The supplied cutter can be adjusted to this radius to
cut the orifice in the plug. The instructions with the plug and cutter has a ruler divided into tenths
of inches. Again, this step is not always necessary as explained above.
An alternative method is to use the orifice equation with the head for a particular skimmer
shown on the previous page and determine the orifice needed to give the required flow for the
volume and draw down time. C = 0.59 is used in this chart.
Example: A 4" skimmer is the smallest skimmer that will drain 39,000 cubic feet in 3 days but a
4" inlet will drain the basin too fast (in 1.9 days) To determine the orifice required use the factor
of 4,803 from the chart below for a 4" skimmer and a drawdown time of 3 days. 39,000 cubic

r2 and solving for r, r = (8.12 / 3.14) and r = 1.61 "
as the cutter can be adjusted and the orifice cut..
Calculate the orifice radius using Area = n
As a practical matter 1.6" is about as close
Factors (in cubic feet of flow per square inch of opening through a round orifice with the head
for that skimmer and for the drawdown times shown) for determining the orifice radius for a
basin's volume to be drained. This quick method works because the orifice is centered and has
a constant head (given above in Step 1).

NC DENR Erosion and Sediment Control
Planning Manual —Estimating Roughness
Coefficients

Appendices
This section describes a method for estimating the roughness coefficient n for
use in hydraulic computations associated with natural streams, floodways, and
excavated channels. The procedure applies to the estimation of n in Manning's
formula (Appen&v 8.05).
The coefficient of roughness n quantifies retardation of flow due to roughness
of channel sides, bottom, and irregularities.
Estimation of n requires the application of subjective judgement to evaluate
five primary factors:
• irregularity of the surfaces of the channel sides and bottom;
• variations in the shape and size of the channel cross sections;
• obstructions in -the channel;
• vegetation in the channel; and
• meandering of the channel.
Procedure For The procedure for estimating n involves selecting a basic value for a straight,
uniform, smooth channel in the existing soil materials, then modifying that
Estimating n value with each of the five primary factors listed above,
Table 8.04a
Basic Value of Roughness
Coefficient for Channel
Materials
In selecting modifying values, it is important that each factor be examined and
considered independently.
Step 1. Selection of basic value of n. Select a basic n value for a straight,
uniform, smooth channel in the natural materials involved. The conditions of
straight alignment, uniform cross section, and smooth side and bottom surfaces
without vegetation should he kept in mind. Thus, basic n varies only with the
material than forms the sides and bottom of the channel. Select the basic n for
natural or excavated channels from Table 8.04a. If the bottom and sides of a
channel consist of different materials, select an intermediate value.
Soil Material
Basic n
Channels in earth
0.02
Channels in fine gravel
0.024
Channels cut into rock
0.025
Channels in coarse gravel
0.028
Step 2. Selection of modifying value for surface irregularity. This factor
is based on the degree of roughness or irregularity of the surfaces of channel
sides and bottom. Consider the actual surface irregularity, first in relation
to the degree of surface smoothness obtainable with the natural materials
involved, and second in relation to the depths of flow expected. if the surface
irregularity is comparable to the best surface possible for the channel materials,
assign a modifying value of zero. Irregularity induces turbulence that calls for
increased modifying values. Table 8.04b may be used as a guide to selection
of these modifying values.

Step 3. Selection of modifying value for variations in the shape and size of
cross sections. In considering this factor, judge the approximate magnitude of
increase and decrease in successive cross sections as compared to the average.
Gradual and uniform changes do not cause significant turbulence. Turbulence
increases with the frequency and abruptness of alternation from large to small
channel sections.
Shape changes causing the greatest turbulence are those for which flow shifts
from side to side in the channel. Select modifying values based on Table
8.04c.
Step 4. Selection of modifying value for obstructions. This factor is based
on the presence and characteristics of obstructions such as debris deposits,
stumps, exposed roots, boulders, and fallen and lodged logs. Take care that
conditions considered in other steps not be double -counted in this step.
In judging the relative effect of obstructions, consider the degree to which
the obstructions reduce the average cross -sectional area at various depths and
the characteristics of the obstructions. Sharp -edged or angular objects induce
more turbulence than curved, smooth -surfaced objects. Also consider the

transverse and longitudinal position and spacing of obstructions in the reach.
Select modifying values based on Table 8.04d.
Step 5. Selection of modifying value for vegetation. The retarding effect
of vegetation is due primarily to turbulence induced as the water Bows around
and between limbs, stems, and foliage and secondarily to reduction in cross
section. As depth and velocity increase, the force of flowing water tends to
bend the vegetation. Therefore, the ability of vegetation to cause turbulence is
related to its resistance to bending. Note that the amount and characteristics of
foliage vary seasonally. in judging the retarding effect of vegetation, consider
the following: height of vegetation in relation to depth of flow, its resistance to
bending, the degree to which the cross section is occupied or blocked, and the
transverse and longitudinal distribution of densities and heights of vegetation
in the reach. Use Table 8.04e as a guide.
Step 6. Computation of n for the reach. The first estimate of roughness
for the reach, n., is obtained by neglecting meandering and adding the basic n
value obtained in step l and modifying values from steps 2 through 5.
n5 = n + E modifying values
Step 7. Meander. The modifying value for meandering is not independent of
the other modifying values. It is estimated from the n obtained in step 6, and
the ratio of the meandering; length to the straight length. The modifying value
for meandering may be selected from Table 8.04f.
Step 8. Computation of n for a channel reach with meandering. Add the
modifying value obtained in step 7, to n,, obtained in step 6.
The procedure for estimating roughness for an existing channel is illustrated
in Sample Problem 8.04a.
Work with natural floodways and streams often requires consideration of a
wide range of discharges. At higher stages, both channel and overbank or
flood plain flow may occur. Usually, the retardance of the flood plain differs
significantly from that of the channel, and the hydraulic computations can be
improved by subdividing the cross section and assigning different n values for
flow in the channel and the flood plain. If conditions warrant, the flood plain
may be subdivided further. Do not average channel n with flood plain it. The
n value for in -bank and out -of -bank flow in the channel may be averaged.

'Meander ratio is the total
length of reach divided
by the straight line
distance.
To compute a roughness coefficient for flood plain flow, consider all factors
except meandering. Flood plain it values normally are greater than channel
values, primarily due to shallower depths of flow. The two factors requiring
most careful consideration in the flood plain are obstructions and vegetation.
Many flood plains have fairly dense networks of obstructions to be evaluated.
Vegetation should be judged on the basis of growing -season conditions.
Description of reach:
Soil —Natural channel with lower part of banks and bottom yellowish
gray clay, upper part light gray silty clay.
Side slopes —Fairly regular; bottom uneven and irregular.
Cross section --Very little variation in the shape; moderate, gradual
variation is size_ Average cross section approximately trapezoidal
with side slopes about 1.5:1 and bottom width about 10 feet. At
bankfull stage, the average depth is about 8.5 feet and the average
top width is about 35 feet.
Vegetation —Side slopes covered with heavy growth of poplar trees,
2 to 3 inches in diameter, large willows, and climbing vines; thick,
bottom growth of waterweed; summer condition with the vegetation
in full foliage.
Alignment —Significant meandering; total length of meandering
channel, 1120 feet; straight line distance, 800 feet.

Dear Mr. Flynn:
The Division of Water Quality received your initial application for stormwater general
permit NCG060000 on October 7, 2010. We -received your next submission oil December 6, 2010.
Because the second submission was incomplete, in order to process your request for a general
permit NCGO20000 we must obtain some additional information. We spoke about our request in .
depth on the phone on January 6, 2011. DWQ has revised our request slightly to have a more
targeted monitoring approach; however DWQ feels that this request is not more burdensome to the
permittee than what we spoke about on the phone.
Please provide the following information:
1. A Description of Well Construction: installation, diameter, depth, design, screen intervals,
construction records, maintenance plan and other relevant information.
2. Cross -Sectional Measurements and Visual Inspection of Stream. Cross -sectional dimensions
and measurements are required in order to provide hydrological information as mine
dewatering and site modification occur. Please submit a plan to provide the following:
a. On Stream "A", at points 1, 2 and 3 as shown on the submitted "Jurisdictional waters
and Groundwater Contour Map", and at a 41h point of the permittee's choosing,
visually inspect, measure, dimension and photograph a cross -sectional profile of the
stream. Provide the depth at bottom and sides, as well as a drawn cross -sectional .
profile at each of these 4 points.
b. The above -described cross -sections and measurements/dimensions/inspections

L Initially after the permit is issued (within 60 days from receipt of the permit)
ii. Yearly until dewatering occurs.
iii. After dewatering is initiated:
1. For the First year after dewatering is initiated: on a auorterlx basis.
2. For the Second and Third years after dewatering is initiated: on a ey arlX
basis.
3. Thereafter as the DWQ Mooresville Regional Office Staff direct.
4. The permittee may request a modification of this schedule after the
first year after dewatering takes place. Modification requests shall be
directed to the DWQ Mooresville Regional Office Staff in writing.
3. Well Monitoring Protocol. DWQ requests further information about your well monitoring
protocol. Please provide the following information:
a. DWQ requires that you monitor the existing wells nearest Stream "A° - labeled'
"2010H1073M" and "2010H1072M" shown on the submitted "Jurisdictional waters
and Groundwater Contour Map". These two wells shall be monitored monthly, at
minimum, and an annual data monitoring report shall be constructed and kept on
site.
b. Additionally, DWQ requests the permittee construct one well is near Stream "A"
outside the buffer area and approximately 30 feet below the discharge from the
pond. This well should be shallow and should intersect the groundwater table. It
should have at least a 10 foot screen interval. As the permittee will need to establish
a base line before the initiation of the mining operation and of dewatering, provide a
monitoring protocol to this end. After dewatering commences, monitoring of this
well shall occur at least on a monthly basis. Provide a detailed site plan Staff as to the
exact location of this well to the DWQ Mooresville Regional Office within 60 days of
receipt of the permit.
c. Provide an explanation of how monitoring data will be analyzed to determine
whether the groundwater hydrology is removed or being maintained. If monitoring
results indicate impacts to any surface water, explain how these impacts may be
abated. Explain how data -will be analyzed to determine or demonstrate the effects of
pumping and dewatering, and propose pumping regimes necessary to reduce impacts
if necessary. More extensive pumping test data should be included if necessary. This
strategy will be reviewed and may be modified by DWQ Regional Office Staff. This
shall be provided within 3 months of receipt of the permit.

Dear Mr. McCloskey:
This letter is to confirm our telephone conversation of October 27 related to the expiration of General Permit No.
NCG020000, the renewal of that General Permit and the status of permit coverage for Franklin industrial Minerals.
As we discussed. the original NCG020000 was issued back in 1992 and carried and expiration date of 1997.
Facilities such as vours were asked to apply for renewal of their General Permit coverage under NCG020000 in
1997. You properly filed your request for coverage under the renewed permit and paid the appropriate renewal fee.
Our Division has not finalized the reissuance of NCG020000 to -date. although we are expecting to reissue the permit
within the next few weeks. Upon reissuance the Division will issue copies of the renewed permit to each facility
which has tiled for renewal of their coverage. In the interim. your facility remains covered by the terms and
conditions of the original version of the NCG020000 permit.
If you have any questions or would like to discuss this letter. please contact me at [phone], extension 548.
Sincerely,
