Dear Mr. Ferguson:
Division personnel have reviewed and approved your application for renewal of the
subject permit. Accordingly,we are forwarding the attached NPDES discharge 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 U.S.Environmental
Protection Agency dated October 15,2007(or as subsequently amended).
The permit authorizes Unimin Corporation to discharge up to 2.0 MGD of treated
wastewater from Red Hill Facility to the North Toe River,a class C-Trout water in the French
Broad River Basin. The final permit includes discharge requirements and/or limitations for
flow,total fluoride,total suspended solids,turbidity,chlorides and other parameters.
The following modification has been made to the final permit:
• Upstream and downstream monitoring for pH has been included in the permit.
This is not an additional requirement because the Unimin-Red Hill facility already
monitors instream for pH and reports the results in the daily monitoring reports.
This-monitoring would be consistent with other mining operations in the North Toe
River. '
• The facility address was changed to 2241 N.C.Highway 197,Bakersville,NC.
• Language regarding the discharge of stormwater was removed from the permit
cover page.

• The effluent page for 0.682 MGD wasteflow and,the accompanying chronic toxicity
requirement at 1.2%was removed from the permit based on the Red Hill Facility's
expansion to 2.0 MGD.
• Additional treatment components were included on the supplement to cover permit
page.
• Language on the supplement to cover permit page was removed regarding an
Authorization to Construct permit because of the submittal of the engineer's
certification in September 2009.
• Language on the supplement to cover permit page regarding the discharge of
stormwater through outfall SD001 was removed. Division staff confirmed that the
Red Hill Facility does not discharge stormwater.
• The monitoring frequency for settleable solids and pH was reduced to weekly.
• The monitoring requirement for ammonia(NH3-N)was removed from the permit
based on facility no longer utilizing ammonia in any process.
• Language in Condition A.2.Chronic Toxicity Permit Limit was modified and a new
paragraph regarding data submittal was added(the second paragraph from the end
of the condition).
• The entire section(Part II in the previous permit)regarding stormwater monitoring,
controls and limitations for permitted discharges has been removed from the permit.
This removal was based on Division confirmation that.the Red Hill Facility does not
discharge stormwater.

2. The total residual chlorine limit and monitoring requirements are only applicable if
facility uses chlorine or chlorine derivatives for disinfection. The Division shall
consider all effluent TRC values reported below 50 ug/L to be in compliance.with
the permit. However, the Permittee shall continue to record and submit all values
reported by a North Carolina certified laboratory (including field certified), even if
these values fall below 50 ug/l. If a method different than
chlorination/dechlorination is used for disinfection, the total residual chlorine limit
will not be applicable.
3. This discharge shall not cause the turbidity of the receiving waters to exceed 10
NTU. If the turbidity exceeds 10 NTU due to natural conditions, the discharge
shall not cause any increase in turbidity of the receiving stream. See Special
Condition A.(7).
4. The pH shall not be less than 6.0 standard units nor greater than 10.0 standard
units.
5. Chronic Toxicity (Ceriodaphnia) Pass/Fail at 3.3%: January, April, July and

procedures outlined in the "North Carolina Ceriodaphnia Chronic.Effluent Bioassay
Procedure," Revised February 1998, or subsequent versions or "North Carolina Phase
II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February 1998) or
subsequent versions. The tests will be performed during the.months of January,
April, July and October. Effluent sampling for this testing shall be performed at the
NPDES permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a
failure or ChV below the permit limit, then multiple-concentration testing shall be
performed at a minimum, in each of the two following months as described in "North
Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-February
1998) or subsequent versions.
The chronic value for multiple concentration tests will be determined using the
geometric mean of the highest concentration having no detectable impairment of
reproduction or survival and the lowest concentration that does have a detectable
impairment of reproduction or survival. The definition of"detectable impairment,"
collection methods, exposure regimes, and further statistical methods are specified in
the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised-
February 1998) or subsequent versions.
All toxicity testing results required as part of this permit condition will be entered on
the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were
performed. If reporting pass/.fail results using the parameter code TGP3B, DWQ Form
AT-1 (original) is sent to the below address. If reporting Chronic Value results using

A. (2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) (cont.)
Should there be no discharge of flow from the facility during a month in which toxicity
monitoring is required, the permittee will complete the information located at the top
of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe
number, county, and the month/year of the report with the notation of"No Flow"in
the comment area of the form. The report shall be submitted to the Environmental
Sciences Branch at the address cited above.
Should the permittee fail to monitor during a month in which toxicity monitoring is
required, monitoring will be required during the following month.
Should any test data from this monitoring requirement or tests performed by the
North Carolina Division of Water Quality indicate potential impacts to the receiving
stream, this permit may be re-opened and modified to include alternate monitoring
requirements--or limits.
If the Permittee monitors any pollutant more frequently than required by this permit,
the results of such monitoring shall be included in the calculation and reporting of the
data submitted on the DMR and all AT Forms submitted._
NOTE: Failure to achieve test conditions as specified in the cited document, such as
minimum control organism survival, minimum control organism reproduction, and
appropriate environmental controls, shall constitute an invalid test and will require
immediate follow-up testing to be completed no later than the last day of the month
following the month of the initial monitoring.

Dear Mr.Perkins:
This is to inform you'that a review of your toxicity self-monitoring report form for the month of April 2011 indicates a violation of the toxicity
limitation specified in your NPDES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity violation(s). Your efforts may
include conducting a Toxicity Reduction Evaluation(TRE),a site-specific study designed to identify the causative agents of effluent toxicity,isolate
the sources of toxicity,evaluate the effectiveness of-toxicity control options,and confirm reductions in effluent toxicity. Please be aware that North
Carolina General Statutes provide for assessment of civil penalties for violations of NPDES permit limitations and requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring and Reporting Requirements.
Please note appropriate mailing addresses for submitting your Discharge Monitoring Reports (DMRs) and Aquatic Toxicity (AT) Test Forms. We
encourage you to review this information; if it would be helpful to discuss this situation or possible solutions to resolve effluent toxicity
noncompliance,please contact Mr.John Giorgino with this office at(919)743-8441.

WHOLE EFFLUENT TOXICITY MONITORING AND REPORTING INFORMATION
➢ The following items are provided in an effort to assist you with identifying critical and sometimes overlooked toxicity testing and reporting
information. Please take time to review this information.The items below do not address or include all the toxicity testing and reporting
requirements contained in your NPDES permit. If you should have any questions about your toxicity testing requirement,please contact Mr.
John Giorgino with the Aquatic Toxicology Unit at(919)743-8401 or another Unit representative at the same number.
➢ The permittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement and that toxicity report forms are
appropriately filed.
➢ The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be entered(with the appropriate
parameter code)on your monthly Discharge Monitoring Report which is submitted to:
North Carolina Division of Water Quality
Central Files
161.7 Mail Service Center
Raleigh,NC 27699-1617
IN ADDITION
Toxicity test data(original"AT"form)must be submitted to the following address:

We have reviewed the subject permit and offer the following comments:
1) I think I discussed this with someone in either NPDES or Stormwater, but we would prefer that the
stormwater outfall be covered under a separate stormwater permit rather than included on the NPDES
permit. Apparently this inclusion was made before the issuance of SW permits and has never been
changed. Since monitoring data is entered in BIMS,this facility always has failure to report violations
in BIMS for outfall 002.
2) Additionally,there is a chlorine limit/monitoring for outfall 001. This is only if the facility uses
chlorine for disinfection,which they don't as it is a process wastewater discharge. Why do we include
this? If the info is not entered correctly in BIMS,the facility will be listed for failure to report TRC
every month. It would be simpler not to include the monitoring requirement when it is not necessary.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
Unimin Corporation is requesting a permit modification for its Red Hill Quartz Plant to increase
flow to 2.0-mgd from it's currently permitted flow of 0.682 mgd in order to increase production.
The Red Hill Quartz Plant performs extraction and mineral processing to produce high purity
quartz. No mining is done at this site. The facility is permitted to discharge into the North Toe.
River, class C-Trout waters, in French Broad River Basin. Outfall 001 discharges process
water. Outfall 002 is an intermittent stormwater discharge.
The wastewater treatment plant consists of:
• Mix-reactor tanks;
• Lime and polymer feed systems;
• 2 thickeners;
• 2 drum filters
• pH adjustment;
• flow.measurement and,
• 2 emergency ponds.
Processes for treatment include neutralization, precipitation, settling, vacuum filtering of solids
and disposal of solids by land filling.
RECEIVING STREAM INFORMATION:
The North Toe River downstream of the facility has a bioclassifrcation rating of Good.
According to the US Fish and Wildlife office, that stretch of North Toe River is designated
critical habitat for the federally endangered Appalachian elktoe. We have records of the
federally endangered Alasmidonta raveneliana (Appalachian elktoe), the state listed Lampsilis
fasciola (Wavy rayed lamp mussel), and Etheostoma acuticeps (Sharphead darter) listed as a
federal species of concern all occuring in that reach of the North Toe.
A section of the North Toe River upstream of this facility is listed on North Carolina's 2006-
303(d) list,,based on turbidity and riparian area loss. This upstream segment has a
bioclassifrcation rating of Fair, The Red Hill Quartz Plant is located,approximately 15 miles
downstream of the impaired segment of the North Toe River.
Unimin Corporation-Red Hill Facility Fact Sheet
NPDES Modification NCO085839
Page 1. .

At this time, DWQ proposes no changes to the previously developed load allocations. Neither
the impairment nor the turbidity violation is directly attributable to this downstream discharge.
Likely, the upstream discharges will be re-evaluated in the future.
INSTREAM MONITORING:
Upstream: Upstream at least 50 feet
Downstream: Downstream at least 300 feet.
Parameters: Fluoride, Turbidity,pH
The fluoride instream standard of 1.8 mg/ L was exceeded both upstream and downstream of
the discharge in 2005, with 7 instances of upstream exceedance in 2005, none in 2006, none in
2007 and none through March 2008.
A review of instream data for 2005 through March 2008 showed no exceedances of the
turbidity standard of 10 NTU for trout streams.
Per Unimin, the cause of the exceedances upstream are unknown. It is speculated that some
quality control problems with upstream discharges occurred and caused sporadic exceedances
of Total Fluoride. Extreme drought conditions could have also been a contributing factor.
Because of the sporadic upstream exceedances, the Division of Water Quality used the 95'th
percentile of the previous 2 years of upstream data for fluoride to calculate the upstream value
for use in calculating the allowable fluoride limit (See explanation under proposed changes).
TOXICITY TEST RESULTS:
Existing: Quarterly Chronic P/F, 1.2% Ceriodaphnia test. JAN APR JUL OCT
Facility has passed all tests since January 2002 except for one failure in January 2004. It was
followed by two passed tests in Feb. and March 2004 and all subsequent tests through July
2007.
Recommendation: Renewal of quarterly chronic test @ 3.3% based on increased flow.
COMPLIANCE REVIEW:
The facility has been in compliance with nearly all permit limits consistently in 2005, 2006
2007 and 2008 YTD. One NOV was issued in November 2006 for exceeding the TSS Limit and
one NOV in 2007 for exceeding the flow,limit.
Unimin is no longer required to conduct the Priority Pollutant analysis based on category of
discharger.
Chlorine is added for disinfection of the intake water. A TRC limit of 28 ug/L was added on
permit renewal in November, 2006 based on trout classification of receiving stream and NC
standard for TRC. An 18 month compliance schedule was given, the TRC limit began June 1,
2008. The TRC limit will continue with this permit modification.
PROPOSED CHANGES:
At the request of the permittee, flow is increased to 2.0 MGD from 0.682 MGD.. TSS
concentration limits were kept the same at 25 mg/ L, based on 40 CFR 436 for similar type
operations. The new mass limit is 417 lb/ day monthly average for TSS, and 834.0 lb/ day
daily max.
Unimin Corporation-Red Hill Facility Fact Sheet
NPDES Modification NCO085839
Page 2

The new fluoride limit is based on the NC WQ Standard of 1.8 mg/L. Instream data for April
2006, 2007 through March 2008 was reviewed. A background upstream fluoride concentration
of 1.07 mg/L was calculated based on the 95'th percentile of the data range. A standard
material balance limit calculation results in an allowable discharge concentration of 23 mg/L,
or 384.0 pounds per day, which is given as a weekly average based on the chronic WQ
standard. A daily maximum limit of two times the weekly average (768.0 lb/day) has been given
based on discussion with Marshall Hyatt of EPA Region 4, Jeff Ferguson of Unimin, and their
attorney, Steve Levitas. The existing fluoride limit is 200.0 pounds per day monthly average
and 400.0 pounds per day daily.maximum at a flow of 0.682 MGD. These limits were based on
BPJ of Best Available Control Technology of 27 mg/L when the permit was first issued.

NPDES Permit Nos:NC0085839 Mitchell County,North Carolina
Dear Mr.Weaver:
Please accept this letter as a request for modification of Unimin Corporation—Red
Hill Facility's NPDES No. NCO085839 to allow for increased production. With this
modification, Unimin requests that the permitted average flow be increased from 0.682
MGD to 2.0 MGD and allow for the monthly average total suspended solids limit to be
increased from 142 lb/dap to 417 lb/dap based on the 25 mg/1 30-dap average effluent
limitation contained in 40 CFR 436. In addition, Unimin requests that the monthly average
total fluoride limit to be increased from 200 lb/dap to 450 lb/day based on best available
control technology at 27 mg/l. The requested levels are sufficient to protect water quality
and are well below available concentrations at this point in the river.
Enclosed please find one signed original and two copies of EPA Form 1 and EPA
Form 2C, proposed waste treatment plant flowsheet, and a major modification permit
processing fee of $400.00. Please note there have been no changes to the waste treatment
plant since issuance of the latest permit.
As this project is very urgent, I am grateful for all efforts you can make to expedite
this permit approval.
Please note that portions of the applications have been stamped ConfidentiaL
Unimin Corporation is requesting that this information be treated as confidential and
thereby protected from public disclosure.
Unimin believes that such information if made public, would divulge technology,
methods and processes entitled to protection as trade secrets of Unimin Corporation.
Accordingly, we are requesting confidentiality of this information under State Statute 143-
215.3.

Mr.Charles H.Weaver,Jr.

In support of this request,Unimin Corporation herein avers:
A. The production of high .purity quartz is a highly competitive industry in which
market position,is very much dependent on possession of the latest technology and
process development
B. The processes and technology associated with Unimin's production of high purity
quartz have been consistently treated by Unimin in its operating policies,procedures
and practices as proprietary and confidential trade secrets.
C. Unimin believes that such processes and technology are in its sole possession and
are not generally available to Unimin's competitors or the public.
D. Such confidential processes and technology which have been developed at great
time and expense to Unimin are the property of Unimin and represent a great value
and competitive advantage to its market position and are an integral part of
Unimin's continuous quartz production operation.
E. The unprotected divulgence of such confidential information would result in an
irreparable harm to the competitive position of Unimin Corporation in this market
If you have any questions regarding this matter, require further information, or
anyway I can assist to expedite the modification approval please do not hesitate to contact
me at [phone] ext. 13. Thank you in advance for your efforts to help accelerate
issuance of the permit

Subject: NPDES Permit Issuance
NPDES Permit NC0085,839
- Unimin Corp-Red Hill Facility
Mitchell County
Dear.Mr.Bradley:
Division personnel have reviewed and approved your application for renewal of the subject
permit. Accordingly,we are forwarding the attached NPDES discharge 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 U.S.Environmental Protection Agency dated May 9, 1994 .
(or as subsequently amended.)
The permit authorizes the Unimin Corporation to discharge up to 0.682 MGD of treated
wastewater from the Red Hill Facility to the North Toe River,a class C Trout water in the French Broad
River Basin. The permit includes discharge limitations/or monitoring for flow,total fluoride,total
suspended solids(TSS),ammonia,settleable solids,turbidity,pH,chloride,total residual chlorine,and
chronic toxicity.
The following modifications have been made in the permit:
• A total residual chlorine limit of 28 ug/1 has been added to reflect the Division's current
policy for protection against chlorine toxicity instream. .If a method different than,
chlorination%dechlorination is used,the total residual chlorine limit will not be applicable.
There is an eighteen month compliance schedule to meet this limit. See Special Condition A

The Division.acknowledges the information that chlorine is used'at the intake,however we ,
must have.effluent data to determine the levels of chlorine that are being discharged. The
chlorine limit of 28 ug/l represents the acute level of protection and is the highest limit that
will be given for any discharger to North Carolina waters. '
The following modification has been made in the final permit,which was not included in the
April 26�1 draft:
■ Stormwater discharge language has been revised to the most current permit language and
includes a Best Management Practices(BMPS)Plan,analytical and qualitative monitoring
requirements,and a schedule of compliance..
Unimin submitted comments on monthly ammonia monitoring in the permit.' After reviewing
the NH3 data from 2004 to present,the Division has determined to maintain the monthly monitoring'
frequency. The monthly NH3 values-ranged from a minimum of 0.1 mg/L to the maximum of 28.2
mg/L. Because of the wide range of concentrations and because the discharge months varied from year
to-year,it is recommended that Unimin continue to sample monthly. If Unimin determines that
ammonia will not be used during the process,then the Division will then give further consideration.
It should be noted that the North Toe River upstream of the Red Hill facility's discharge is listed
as an impaired stream on North Carolina's 2006 Draft 303(d)list. This means that the stream does not-
meet all water quality standards. It is the plan of the Division to work for the improvement and .
recovery of the River. In the'event of the continuance of problems,the future may require the removal
of direct point source dischargers to the North Toe River for the health of the stream.
If any parts,measurement frequencies or sampling requirements contained in this permit are
Unacceptable to you,you have the right to an adjudicatory hearing upon written request within thirty'
(30)days following receipt of this letter. This request must be in the form of a written petition,
conforming to Chapter 150B of the North Carolina General Statutes,and filed with the office of
Administrative Hearings,6714 Mail Service Center,Raleigh,North Carolina 27699-6714. Unless such a
demand is made,this permit shall be final and binding.
Please take notice that this permit is not transferable. The Division may require
modification or revocation and reissuan'ce of the permit. This permit does not affect the legal
requirements to obtain other permits,which may be required by the Division of Water Quality,or
permits required by the Division of Land Resources,Coastal Area Management Act,or any other'
Federal or Local governmental permits may be required.

PART II .
STORMWATER MONITORING,CONTROLS AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A. STORMWATER BEST MANAGEMENT PRACTICES(BMPS)PLAN
'I.The permittee shall implement stormwater BMPs to ensure that contaminants do not
enter surface waters via stormwater that comes in contact with any unstabilized
overburden,raw materials,intermediate products,finished products,byproducts or waste
products located on the site covered by this permit.A BMP Plan shall be developed in
accordance with the requirements of this section.The BMP Plan requirement,or portions of
the plan requirement,may be met by'utilizing appropriate requirements in other
documented plans specific to the permitted facility.
2.Management of Stormwater Runoff and Runon. The permittee shall maintain stormwater
BMPs for land disturbance areas-and outside process areas. In addition,controls should be
used to limit or isolate selected land disturbance and process areas and limit the amount of
off site stormwater runon to those areas.Appropriate Best Management Practices(BMPs)
should be used to divert,infiltrate,reuse or otherwise manage stormwater runoff and
runon in a manner that reduces pollutants in stormwater discharges leaving the site.
Appropriate BMPs may include but are not limited to:vegetative swales,berms,use of
reclaimed mine areas, and reuse of collected stormwater(such as for an industrial process
or as an irrigation source).
3.BMP Controls Inspection and Maintenance.All stormwater BMPs shall be inspected by
or under the direction of the permittee at least once every seven calendar days and within
24 hours after any storm event that results in a discharge.The BMPs implemented shall be
operated and maintained so that they are cleaned out when the sediment storage capacity
has been reduced by 50%.If any visible sedimentation is leaving the property,corrective
action shall be taken to reduce the discharge of sediments.Visible sedimentation found
offsite shall be recorded with a brief explanation as to the measures taken to prevent future
releases as well as;any measures taken to remove the sediment that left the site.All other
stormwater specific controls(e.g. oil/water separators)shall be inspected and qualitatively .
monitored on a semiannual schedule,once in the fall(September-November)and once
during the spring(April June).A log of sampling data and of activities taken to implement
BMPs associated with the vehicle maintenance activities shall be maintained and
incorporated into the BMP Plan and kept onsite for the duration of the permit term and
made available to the Director upon request.
4.Erosion and Sedimentation Control.The permittee shall implement the management
practices and the erosion and sedimentation control measures that are included in the
mining permit or erosion and sedimentation control permit issued by the Division of Land
Resources. Compliance with the issued permit is considered a requirement of this permit.
Any deviation from the issued permit, or amendments to the issued permit that impacts

Permit Number: NCO085839 "
Resources. Compliance with the issued permit is considered a requirement of this permit:;
Any deviation from the issued permit, or amendments to the issued permit that impacts
Water quality shall constitute a violation of the terms and.conditions of this permit.A
signed copy of the issued permit including the approved erosion and sedimentation control
measures and the reclamation plan shall be maintained on the site at all times. Once an area
is released by the Division of Land Resources in accordance with NCGS Chapter 74,Article
7,it shall no longer be subject to this permit.
5. Preventive Maintenance Inspections and Good.Housekeeping Practices.Equipment
utilized during mining activity on a site must be operated and maintained in such a manner
as to prevent potential or actual pollution of the surface water or ground waters of the state.,
Fuels,lubricants, coolants, and hydraulic fluids,or any other petroleum products, shall not
be discharged on the ground or into surface waters. Spent fluids shall be disposed of in a
manner so as not to enter the surface waters or-ground waters of the state and.in
accordance with applicable federal disposal regulations. Any spilled fluids shall be cleaned .
up to.the maximum extent practicableand disposed of in a mariner that does not allow their
entry into the surface waters or ground waters of the state.
6. Secondary Containment.The permittee shall provide secondary containment for bulk
storage of liquid materials,storage of Section 313 of Title III of the Superfund Amendments
and Reauthorization Act (SARA)water priority chemicals,or storage of hazardous liquids
substances to prevent leaks and spills from contaminating stormwater runoff. If the
secondary containment devices are connected directly_to stormwater"conveyance systems,
the connection shall be controlled by manually activated valves or other similar devices
(which shall be secured with a locking mechanism) and any stormwater that accumulates in
the containment area shall be at a minimum visually observed for color,foam, outfall ;
staining,visible sheens and dry weather flow,prior to release of the accumulated
stormwater.Accumulated stormwater shall be-released if found to be uncontaminated by
the material stored within the containment area.
SECTION B: ANALYTICAL AND QUALITATIVE MONITORING REQUIREMENTS.
FOR DISCHARGES COMPOSED ENTIRELY OF STORMWATER
Analytical monitoring for stormwater discharges shall be performed for parameters as. .
specified in Tables 1 through 2. All analytical monitoring shall be performed during a
representative storm event as defined in Section D. Definitions. -
In situations where stormwater runoff is controlled by some type basin or `
retention/detention pond, the following provisions are applicable for sample collection for
analytical monitoring:
@@Analytical monitoring for stormwater discharges from basin or other similar control
structures must be performed within the first 30 minutes of discharge. ;

Permit Number: NCO085839
• Analytical monitoring for a basin/pond designed to contain the 10-year design:storm (see
Section D. Definitions) without discharging is not required. Qualitative monitoring for
color,foam, outfall staining,visible sheen and dry weather flow is the only monitoring
requirement.
• Analytical and-qualitative monitoring are not required for a basin/pond designed to
contain the 25-year, 24-hour storm (see Section D. Definitions)without discharging. A
basin/pond meeting this provision is considered a non-discharging stormwater control.. '
1. Analytical Monitoring for Stormwater Discharges from Land Disturbance and Process "
Areas.
Analytical monitoring for stormwater discharges from land disturbance and process areas
shall be performed as specified in Table 1.

2. Qualitative Monitoring for Stormwater Discharges from Land Disturbance Areas,'
Process Areas and Vehicle Maintenance Areas.
Qualitative monitoring requires a visual inspection of all stormwater outfalls with
stormwater runoff from land disturbance, process or vehicle maintenance areas regardless
of representative outfall status or cut-off concentrations and shall be performed as specified
below in Table 2. No analytical tests are required.
The first qualitative monitoring event during the term of'the permit must coincide with
the initial analytical monitoring event (regardless of the season).All other qualitative
monitoring will be performed twice per year, once m the spring(April-June) and once in
the fall (September-November) and does not need to be performed during a representative
storm event.

EPA Region IV
Through: Dave GoodrichVC1
From: Jacquelyn M. NowellW
VIYtf`'
Subject: North Toe River Mining Dischargers
French Broad River Basin
Mitchell County,North Carolina
Background
There are six feldspar and quartz mines discharging into the North Toe River in the
French Broad River basin (subbasin 040306). The facilities are listed here in order, from
upstream to downstream:
• Unimin- Schoolhouse Facility (NC0000361) —2.16 MGD
• Feldspar Mines (NC0000353) —3.5 MGD
• Unimin-Crystal Facility (NC0084620) —0.36 MGD
• K-T Feldspar Mines (NC0000400) — 1.73 MGD
• Unimin—Quartz Facility (NC0000175) —3.6 MGD
• Unimin—Red Hill Facility (NC0085839) —0.682 MGD
Please see the attached schematic that represents the mine locations on the North Toe
River. Most of these facilities have been discharging since the early 1980's. The
exception is the Red Hill Facility that started discharging in 1995 and is located
approximately 20 miles downstream of the other mines and is not relevant to this
discussion from the standpoint that no interaction occurs between this plant and any
other. Therefore, this discussion will only include the mines above the confluence of the
South Toe River. It should also be noted that the Unimin — Crystal Facility discharges
effluent into the Feldspar Mines facility. There is the possibility of a separate discharge
in the future; therefore the facility has received a fluoride allocation.
The primary area of concern is the discharge of fluoride from these facilities. The North
Carolina water quality standard for fluoride is 1.8 mg/l. The allowable fluoride loading
for the North Toe River was determined in 1986 and has been allocated to these mines as
a group instead of individual allocations. This approach of allocating the total fluoride

load to a section of the North Toe River is similar to other methods used by the Division,
including nutrient control strategies in the Neuse and Tar-Pamlico River basins. Similar
to a "bubble permit"(used in the Air Quality program), some discharges may cause
localized impacts. However, the overall goal of the allocation method is to protect water
quality while allowing some flexibility for the dischargers to maintain compliance. The
Division and EPA have approved this approach for 17 years.
The total pounds per day of fluoride allocated are 574. The permitted fluoride
allocations for each of the mines is as follows:

Unimin-Schoolhouse 109 218

K-T Feldspar 132 264
Unimin-Quartz 109 436
�t�](A)IIOC�itldDil " fi s'4 3<9
These allocations for the mines have been assigned upon all past permit renewals. This
fluoride loading of 5741bs/day is based on:
1) a summer 7Q10 flow of 45 cfs in the North Toe River just below Little Bear Creek,
2) the current water quality standard for fluoride of 1.8 mg/1, and
3) a background fluoride concentration of 0.05 mg/l.
The 1985 wasteflows for three of the quartz processing mines were used to develop the
fluoride loading:
1)Feldspar @ 1985 Qw = 3.50 MGD
2) KT Feldspar @ 1985 Qw = 2.02 MGD
3) Unimin-Quartz @ 1985 Qw = 4.32 MGD
9.84 MGD = 15.25 cfs
Fluoride loading - (45 cfs + 15.25 cfs)(1.8 mg/1)— (45 cfs)(0.05 mg/1)
_ (60.25)(1.8)—2.25 cfs.mg/l
= 108.45 —2.25 = 106.2 cfs.mg/1
= 106.2 cfs.mg/1 * 5.39 = 572 lbs/day — 574 lbs/day
(Assume the difference is attributable to rounding)
Water Quality Evaluation
There are no federal effluent guidelines for mines that discharge fluoride. The purpose of
this memorandum is to evaluate water quality as it relates to previous permit decisions
and propose a 2003 permit strategy.

1
. fd
The Division uses a weight of evidence approach when assessing water quality. That is,
all available data are reviewed and evaluated to determine the appropriateness of certain
actions. There are three categories of information in this case:
• Instream biological assessments
• Whole-effluent toxicity testing
• Instream chemical data
Instream biological data are the most directly reliable measurements of stream health and
are, therefore, given the greatest consideration. Whole-effluent toxicity testing also is
given a lot of weight during deliberations. It is not a direct measurement of stream
conditions, but it is a direct measurement of the interaction between wastewater and
species that inhabit the stream or river. The Division also considers comparison of
physical or chemical measurements to existing water quality standards. In the presence
of all three categories of information, contraventions of water quality standards, although
considered serious, are given the least amount of weight. The reason for this is that
comparisons to numeric criteria (which are based on whole-effluent toxicity testing) are
indirect measurements of the biota in the stream. All of this information is valuable, but
North Carolina chooses to make a comprehensive critical evaluation of all available data.
Use Support
There are no segments of the North Toe River listed on the North Carolina 2003 303(d)
impaired stream list. There are approximately 556 miles of the North Toe River that are
rated fully supporting designated uses including the river reaches receiving effluent from
these mines.
Instream Biological Assessment
The benthic macroinvertebrate data for the North Toe River below all the quartz mines
demonstrate good water quality. The most recent evaluation was in 1997 at State Road
1162 at Penland, Mitchell County. This is located just 0.5 miles downstream of the
Unimin-Quartz discharge. There has been improvement in the biological rating over the
years from a poor rating in August 1988 to a good-fair rating in 1989 and 1992.
Macroin vertebrate data for the most upstream station above the quartz mines, North Toe
River at US19E at Ingalls, Avery County, indicate a rating of excellent water quality as of
July 1997. The table below indicates North Toe River biological monitoring stations and
their biological ratings during the 10 year period between 1987 and 1997.

Whole Etluent Toxicity Testing
All the quartz mines have quarterly whole effluent toxicity tests based on the potential for
toxic effects on the receiving stream. (Please note that Unimin-Crystal has a toxicity
limit, however because it discharges into the Feldspar Mines WWTP, they do not conduct
individual toxicity tests.) Since 1998, there have been 91 tests conducted by the five
quartz mines with a 93% passing rate. There have only been 6 failures of all the tests
conducted in the past four years. The majority of the failures occurred at the same
facility. The Unimin-Schoolhouse plant accounted for four of the six failures. The cause
of this toxicity is unknown. However, it should be noted that Unimin-Schoolhouse been
compliant since August 2001.

Instream Chemical Monitoring by Facilities
All the facilities conduct instream self-monitoring for turbidity, fluoride and pH, both
upstream and downstream of their outfalls. This is to help determine the effect of the
discharges on.the water quality in the North Toe River. Instream fluoride data from the
time period of January 1999 to August 2002 were reviewed for the preceding five
facilities. During this time period, the monthly averages for instream fluoride have
shown no exceedances of the water quality standard either upstream or downstream of the
Unimin-Schoolhouse and Feldspar facilities. The average upstream value for the
Schoolhouse facility was 0.15 mg/1 and the average downstream value was 0.26 mg/1.
The average upstream value for the Feldspar facility was 1.29 mg/l and the average
downstream value was 1.2 mg/l.
There were a total of 327 fluoride observations in the stream among these five
dischargers with 30 values >1.8 mg/l. This was 9% of the total monthly observations
with 91% within the standard. Most of the instream fluoride values > 1.8 mg/1 standard
occurred upstream and downstream of the K-T Feldspar discharge. This, more than
likely, occurred as a result of the proximity of the Feldspar Mines discharge which is only
0.6 miles above the K-T Feldspar Mines discharge. The breakdown of instream
observations of values > 1.8 mg/l are:

SR 1162 at Penland Bridge 42 3 7%

Ambient Monitoring Data
The Division conducts ambient monitoring in the North Toe River at two sites. The first
station is at US Highway 19E near Ingalls, NC nearly 1 mile above the Unimin-
Schoolhouse Quartz mine. The second station is at State Road 1162 at Penland
approximately 0.8 miles below the.Unimin-Quartz outfall. These stations are above the
most upstream mine and below the most downstream mine. Since January 1999, there
have been 30 samples of fluoride taken. There have been only 3 values > 1.8 mg/l and
these occurred in February 2000, February 2001 and June 2001. This indicates that 90%
of the ambient samples in the past 4 years have been < 1.8 mg/l.
Discussion of Water Quality Information
An overall view of water quality in this segment of the North Toe River indicates that the
biological assessment shows improving water quality conditions. The toxicity data
indicates that the discharges are not toxic or causing toxicity instream. There is greater
than 90% compliance with the toxicity limits. Self monitoring instream data conducted
by the discharges does demonstrate that some instream fluoride standard exceedances
occur. The majority are below K-T Feldspar, and it is concluded that these occur because
the two dischargers are in such close proximity and North Carolina (with EPA approval)
has used a "bubble" permitting approach, which allows some localized impacts by design.
However, the average instream fluoride values collected between January 1999 and
August 2002 show that upstream and downstream of all the dischargers, the instream
fluoride average is below the standard of 1.8 mg/l.
DWO Recommendation
The Division recommends that the allocations for the North Toe River dischargers remain
the same. Water quality data show that there is no impairment in the stream, there have
been minimal toxicity problems, and the numeric water quality standard is being
protected>90% of the time. It recommended that all the feldspar and quartz mines have
their permits reissued at the existing fluoride allocations.

Dear Mr. Ferguson:
Division personnel have reviewed and approved your application for modification of the subject
permit. Accordingly,we are forwarding the attached,NPDES discharge 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 U.S. Environmental Protection Agency dated October 15,
2007 (or as subsequently amended).
The following changes from the draft previously sent to you for review are:
➢ Stormwater outfall 002 has been renamed to SD001. This is to resolve a problem with our
Basinwide Information Management System (BIMS) database,which creates erroneous error
messages when discharge data is not entered for Outfall 002. Renaming the outfall will not cause
any differences in the permit requirements for stormwater management.
➢ The number of thickeners, drum filters and emergency ponds has been corrected.
If any parts,measurement frequencies or sampling requirements contained in this permit are
unacceptable to you,you have the right to an adjudicatory hearing upon written request within thirty (30)
days following receipt of this letter. This request must be in the form of a written petition, conforming to
Chapter 150B of the North Carolina General Statutes,and filed with the Office of Administrative Hearings.

PART II
STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION A. STORMWATER BEST MANAGEMENT PRACTICES (BMPS) PLAN
1. The permittee shall implement stormwater BMPs to ensure that contaminants do
not enter surface waters via stormwater that comes in contact with any unstabilized
overburden, raw materials, intermediate products, finished products, byproducts or
waste products located on the site covered by this permit. A BMP Plan shall be
developed in accordance with the requirements of this section. The BMP Plan
requirement, or portions of the plan requirement, may be met by utilizing appropriate
requirements in other documented plans specific to the permitted facility.
2. Management of Stormwater Runoff and Runon. The permittee shall maintain
stormwater BMPs for land disturbance areas and outside process areas. In addition,
controls should be used to limit or isolate selected land disturbance and process areas
and limit the amount of off site stormwater runon to those areas. Appropriate Best
Management Practices (BMPs) should be used to divert, infiltrate, reuse or otherwise
manage stormwater runoff and runon in a manner that reduces pollutants in
stormwater discharges leaving the site. Appropriate BMPs may include but are not
limited to: vegetative swales, berms, use.of reclaimed mine areas, and reuse of
collected stormwater (such as for an industrial process or as an irrigation source).
3. BMP Controls Inspection and Maintenance. All stormwater BMPs shall be inspected
by or under the direction of the permittee at least once every seven calendar days and
within 24 hours after any storm event that results in a discharge.. The BMPs
implemented shall be operated and maintained so that they are cleaned out when the
sediment storage capacity has been reduced by 50%. If any visible sedimentation is
leaving the property, corrective action shall be taken to reduce the discharge of
sediments. Visible sedimentation found offsite shall be recorded with a brief
explanation as to the measures taken to prevent future releases as well as any
measures taken to remove the sediment that left the site. All other stormwater specific
controls (e.g. oil /water separators) shall be inspected and qualitatively monitored on a
semiannual schedule, once during the first half of the year (January—June) and once
during the second half of the year (July - December), with at least 60 days separating
inspection dates (unless performed more frequently). A log of sampling data and of
activities taken to implement BMPs associated with the vehicle maintenance activities
shall be maintained and incorporated into the BMP Plan and kept onsite.for the
duration of the permit term and made available to the_Director upon request.

Permit Number: NC0085839
4. Erosion and Sedimentation Control. The permittee shall implement the
management practices and the erosion and sedimentation control measures that are
included in the mining permit or erosion and sedimentation control permit issued by
the Division of Land Resources. Compliance with the issued permit is considered a
requirement of this permit. Any deviation from the issued permit, or amendments to
the issued permit that impacts water quality shall constitute a violation of the terms
and conditions of this permit. A signed copy of the issued permit including the
approved erosion and sedimentation control measures and the reclamation plan shall
be maintained on the site at all times. Once an area is released by the Division of Land
Resources in accordance with NCGS Chapter 74, Article 7, it shall no longer be
subject to this permit.
5. Preventive Maintenance Inspections and Good Housekeeping Practices. Equipment
utilized during mining activity on a site must be operated and maintained in such a
manner as to prevent potential or actual pollution of the surface water or ground
waters of the state. Fuels, lubricants, coolants, and hydraulic fluids, or any other
petroleum products, shall not be discharged on the ground or into surface waters.
Spent fluids shall be disposed of in a manner so as not to enter the surface waters or
ground waters of the state and in accordance with applicable federal disposal
regulations. Any spilled fluids shall be cleaned up to the maximum extent practicable
and disposed of in a manner that does not allow their entry into the surface waters or
ground waters of the state.
6. Secondary Containment. The permittee shall provide secondary containment for
bulk storage of liquid materials, storage of Section 313 of Title III of the Superfund
Amendments and Reauthorization Act (SARA) water priority chemicals, or storage of
hazardous liquids substances to prevent leaks and spills from contaminating
stormwater runoff. If the secondary containment devices,are connected directly to
stormwater conveyance systems, the connection shall be controlled by manually"
activated valves or other similar devices (which shall be secured with a locking
mechanism) and any stormwater that accumulates in the containment area shall be at
a minimum visually observed for color, foam, outfall staining, visible sheens and dry
weather flow, prior to release of the accumulated stormwater. Accumulated
stormwater shall be released if found to be uncontaminated by the material stored
within the containment area.
SECTION B: ANALYTICAL AND QUALITATIVE MONITORING REQUIREMENTS
FOR DISCHARGES COMPOSED ENTIRELY OF STORMWATER
Analytical monitoring for stormwater discharges shall be performed for parameters as
specified in Tables 1 through 2. All-analytical monitoring shall be performed during a
representative storm event as defined in Section D. Definitions.
In situations where stormwater runoff is controlled by some type basin or
retention/detention pond, the following provisions are applicable for sample collection
for analytical monitoring:
Analytical monitoring for stormwater discharges from a basin or other similar control
structures must be performed within the first 30 minutes of discharge.
10

Permit Number: NCO085839
• Analytical monitoring for a basin /pond designed to contain the 10-year design
storm (see Section D. Definitions) without discharging is not required. Qualitative
monitoring for color, foam, outfall staining, visible sheen and dry weather flow is the
only monitoring requirement.
• Analytical and qualitative monitoring are not required"for a basin/pond designed to
contain the 25-year, 24-hour storm (see Section D. Definitions) without discharging. A
basin/ pond meeting this provision is considered a non-discharging stormwater
control.

In support of this request,Unimin Corporation herein avers:
A. The production of high purity quartz is a highly competitive industry in which
market position is very much dependent on possession of the latest technology and
process development
B. The processes and technology associated with Unimin's production of high purity
quartz have been consistently treated by Unimin in its operating policies,procedures
and practices as proprietary and confidential trade secrets.
C. Unimin believes that such processes and technology are in its sole possession and
are not generally available to Unimin's competitors or the public.
D. Such confidential processes and technology which have been developed at great
time and expense to Unimin are the property of Unimin and represent a great value
and competitive advantage to its market position and.are an integral part of
Ummin's continuous quartz production operation.
E. The unprotected divulgence of such confidential information would result in an
irreparable harm to the competitive position of Unimin Corporation in this market.
In addition, Unimin Corporation would like to request the following
revisions/corrections to each NPDES Permit
During the most recent amendment to the Crystal NPDES Permit No. NC0084620,
the upstream/downstream sampling locations were inadvertently changed to "U-upstream at
Altapass Road" and "D-downstream at the footbridge in the Town of Spruce Pine."
Unimin would like to request that this be changed back to "U-upstream at least 50 feet" and
"D-downstream at least 300 feet" Also, Unimin would like to request that the pH be
sampled at the effluent only and remove the unnecessary requirement to sample upstream
and downstream daily.
Unimin would like to request that the requirements to sample Oil and Grease be
removed from both Quartz/Feldspar NPDES Permit No. NC0000175 and Schoolhouse
NPDES Permit Na NC0000361. There have been no hits at either facility and this
monitoring requirement was imposed due to stating that there are possible leaks and drips
from mobile equipment as all facilities have. Unimin does not believe Oil and Grease to be
present at the discharge and would like to request that this monitoring requirement be
removed from both permits.
Unimin would like to request that the requirement to sample ammonia monthly be
removed from the Red Hill NPDES Permit No.NC0085839 as the facility no longer utilizes
ammonia in any process or research.

Section D:Summary of Finding/Comments(Attach additional sheets of narrative and checklists as necessary)
Present during the inspection were Dennis Johnson (Unimin)and Mike Bowden(EPA).
Operation and Maintenance:
A layer of solids were apparent in the clarifier trough and the effluent flume area. These solids have to
be removed and not flushed through the system to the river; these settled solids have a likelihood of
toxicity due to the addition of polymers in the process. Keeping track of solids buildup and developing a
schedule.to remove them should become a routine practice,
- -- -- -- - -- ---------------------------=--
Sampling: - - - - - -- -The pH buffer was expired. New pH buffer has to be purchased immediately. It is imperative that
proper pH buffers be used given the amount of pH adjustments made throughout this industrial
process.
The downstream sampling of the Toe River should be moved-100 feet further downstream. This will
allow for a more representative sampling of the effluent with the river.
Staff time of travel from river to lab for field parameters is at or close to 15 minutes. pH.is supposed to
be measured in-situ ideally, but within 15 minutes if in-situ is not viable. A portable meter that can be
brought to the river to.sample pH should be used.
Effluent sampling equipment was gathering a 30 ml aliquot; at a minimum a 100 ml aliquot is required
for proper sampling. Also the sampler tubing was at the bottom of the effluent trough in the layer of
solids. The tubing needs to be raised to midstream.

Dear Mr. Jussila:
Enclosed please fmd a copy of the Bioassay Compliance Inspection conducted on April 8, 2014.
The aquatic toxicity test, using composite samples of effluent discharged from Unimin Red Hill
Facility, has been completed. Unimin Red Hill Facility has an effluent discharge permitted that is
2.0 million gallons per day entering the North Toe River(7Q10 of 90.0 CFS). Whole effluent
samples were collected on April 8 and April 10,2014 for use in a chronic Ceriodaphnia dubia
multiple dilution toxicity test. The test using these samples passed the chronic toxicity test.
Please refer to the enclosed inspection report for additional sample results obtained. If you or your
staff have any questions,please call me at 828-296-4500.
Sincerely,
Linda Wiggs

Sampling instructions
1. SPLIT TESTS: Make sure the collector fills out,prints,and signs both the ATU sample collection form and the facility/contract
laboratory Chain of Custody(COC)form. If one person collects the sample,and another individual splits the sample,both should
sign the COC and the ATU sample collection form. All information on both COC and the ATU sample collection form should agree
(Le.,the date/time/signature for the collector,relinquished by/date/time,site description,pipe#,etc.) ATU uses only"true"splits,for
certified laboratory evaluations. A split sample is a single,well mixed,equally divided,composite or grab sample,sent to different
laboratories to conduct whole effluent toxicity tests. A well mixed sample before each pour is critical to keep any effluent solids
from settling to the bottom. DWQ staff should be there to observe and instruct the facility staff in the collection/split process to
insure the sample is handled correctly. Ideally the DWQ staff should perform the split. If extenuating circumstances(Le,late sarr6le
collection times,etc.)would make this impractical,it should be noted on the sample collection form that DWQ staff was not present
at the time.of the sample split. If the facility personnel collects and splits the sample,they need to sign the ATU sample collection
form as the collector,and also that they relinquished the sample to DWQ staff. DWQ staff will then need to sign and put the time
that they received the sample. Also, any additional information noted about the sample would be helpful to record on the ATU
sample collection form and the facility's COC(things such as color,smell;floating solids,suspended solids,etc.)
2. The person collecting the sample must sign the form for"Collector(signature)"at the bottom of page 1. Any subsequent transfer of
the sample must be recorded in the"Additional Sampler Handler records". In the"Collectors(print)" section at the top of page 1,
print the name of all collectors involved in the process. If the collector or additional sampler handler is a facility representative,
indicate this on the form.
3. With the adoption of the new chronic toxicity sampling schedule.on January 1't,2011,samples may be collected earlier than 1000
hours. We do request notification,however,if a sample is to be collected earlier.than_0600 hours. The maximum.holding time,for
chronic toxicity samples is 36 hours for first use and 72 hours from first use for test renewals. The maximum holding time is 36
hours for acute toxicity samples. The holding time for composite samples begins at the time.of completion of the 24-br composite.
4. Rinse sample container with sample before filling. Completely fill the sample with no airspace.
5. Constant Time/Constant Volume composite samples should be at least 100 mLs volume per sample and collected at least every 20
minutes unless the detention time of the facility is>24 hours. More information on types of composites can be found in"NPDES
Permit Standard Conditions".
6. Sample collection material may be tempered glass,polyethylene,perfluorocarbon plastics including Teflon®, 304 or 316 stainless
steel,polypropylene,polyvinylchloride,Tygont or silicone. All non-perfluorocarbon plastics should be discarded after use. DWQ
staff should not reuse non-perfluorocarbon plastics(polypropylene,LDPE,HDPE,polyvinylchloride, etc.)at different facilities for
collecting effluent samples. Tempered glass and perfluorocarbon(Teflon)plastics may be reused after bioassay cleaning.
7. All samples should be iced during collection and transport to ensure a sample holding temperature of<_6°C. The sample must be
received at<_6°C or the sample will be invalid. Be sure to completely fill the coolers with ice and use large coolers whenever
possible. This is particularly crucial for shipping samples during warm weather months. Also,please notify ATU staff if samples
are being mailed in multiple coolers.

This is to inform you that a review of your toxicity self-monitoring report form for the month of March 2011 indicates a violation of the toxicity
limitation specified in your NPDES Permit.
You should take whatever remedial actions are necessary to eliminate the conditions causing the effluent toxicity violation(s). Your efforts may
include conducting a Toxicity Reduction Evaluation(TRE),a site-specific study designed to identify the causative agents of effluent toxicity,,isolate
the sources of toxicity,evaluate the effectiveness of toxicity control options,and confirm reductions in effluent toxicity. Please be aware that North
Carolina General Statutes provide for assessment of civil penalties for violations of NPDES permit limitations and requirements.
The reverse side of this Notice contains important information concerning your Whole Effluent Toxicity Monitoring and Reporting Requirements.
Please note appropriate mailing addresses for submitting your Discharge Monitoring Reports (DMRs) and Aquatic Toxicity(AT) Test Forms, We
encourage you to review this information; if it would be helpful to discuss this situation or possible solutions to resolve effluent toxicity
noncompliance,please contact Mr.John Giorgino with this office at(919)743-8441.

WHOLE EFFLUENT TOXICITY MONITORING AND REPORTING INFORMATION
➢ The following items are provided in an effort to assist you with identifying critical and sometimes overlooked toxicity testing and reporting
information. Please take time to review this information.The items below do not address or include all the toxicity testing and reporting
requirements contained in your NPDES permit. If you should have any questions about your toxicity testing requirement,please contact Mr.
John Giorgino with the Aquatic Toxicology Unit at(919)743-8401 or another Unit representative at the same number.
➢ The permittee is responsible for ensuring that toxicity testing is conducted according to the permit requirement and that toxicity report forms are
appropriately filed.
➢ The reporting of whole effluent toxicity testing data is a dual requirement. All toxicity test results must be entered(with the appropriate
parameter code)on your monthly Discharge Monitoring Report which is submitted to:
North Carolina Division of Water Quality

➢ Toxicity test results shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period
(eg,January test result is due by the end of February).
➢ Toxicity test condition language contained in your NPDES permit may require use of multiple concentration toxicity testing upon failure of any
single quarterly toxicity test. If the initial pass/fail test fails or if the chronic value is lower than the permit limit,then at least two multiple
concentration toxicity tests(one per month)will be conducted over the following two months. As many analyses as can be completed will be
accepted. If your NPDES permit does not require use of multiple concentration toxicity testing upon failure of any single quarterly test, you
may choose to conduct either single concentration toxicity testing or multiple concentration toxicity testing per the Division's WET enforcement
initiatives effective July 1, 1999. Follow-up multiple concentration toxicity testing will influence the Division's enforcement response.
➢ Toxicity testing months are specified by the NPDES Permit,except for NPDES Permits which contain episodic toxicity monitoring
requirements(eg,if the testing months specified in your NPDES permit are March,June,September,and December,then toxicity testing must
be conducted during these months).
➢ If your NPDES Permit specifies episodic monitoring and your facility does not have a discharge from January 1-June 30,then you must provide
written notification to the Environmental Sciences Section by June 30 that a discharge did not occur during the first six months of the calendar
year.
➢ If you receive notification from your contract laboratory that a test was invalidated,you should immediately notify the Environmental Sciences
Section at(919)743-8401 and provide written documentation indicating why the test was invalidated and the date when follow-up testing will
occur.
➢ If your facility is required to conduct toxicity testing during a month in which no discharge occurs,you should complete the information block
located at the top of the AT form indicating the facility name,permit number,pipe number,county and the month/year of the subject report.
You should also write"No Flow"on the AT form,sign the form.and submit following normal procedures.
➢ The Aquatic Toxicity Test forms shall be signed by the facility's Operator in Responsible Charge(ORC)except for facilities which have not
received a facility classification. In these cases,a duly authorized facility representative must sign the AT form. The AT form must also be
signed by the performing lab supervisor.
➢ To determine if your AT test forms were received on time by the Division of Water Quality,you may consider submitting your toxicity test
results certified maj return receipt requested to the Environmental Sciences Section.

Mitchell County
Dear Mr. Jussila:
Enclosed please find a copy of the Bioassay Compliance Inspection conducted on March
8, 2011. The aquatic toxicity test using composite samples of effluent discharged from Unimin
Red Hill Facility has been completed. Unimin Red Hill Facility has an effluent discharge permitted
that is 2.0 million gallons per day entering the North Toe River (7Q10 of 90.0 CFS).
Whole effluent samples were collected on March 8 and March 10, 2011 for use in a
chronic Ceriodaphnia dubia multiple dilution toxicity test. The test using these samples passed
with a chronic value of 4.67% which is greater than the facility limit of 3.3%.
These samples were split and sent to Meritech laboratories. The chronic Ceriodaphnia
dubia multi-concentrations toxicity test run by Meritech resulted in a ChV of 2.33%. Meritech test
results and ATU's results are within one test concentration level of each other, which is within the
guidelines for assessing comparability of split test results for multi-concentration test.
Please refer to the enclosed inspection report for additional observations and comments.
If you or your staff have any questions, please call me at 828-296-4500.

On-Site Inspection Report
LABORATORY NAME: Unimin Corporation - Red Hill Plant
NPDES PERMIT#: NCO085839
ADDRESS: P.O. Box 588
Spruce Pine, NC 28777
CERTIFICATE#: 560
DATE OF INSPECTION: June 16,2009
TYPE OF INSPECTION: Industrial Maintenance
AUDITOR: Jason Smith
LOCAL PERSON CONTACTED: Bruce Perkins
I. INTRODUCTION:
This laboratory was inspected to verify its compliance with the requirements of 15A NCAC 2H .0800 for the
analysis of environmental samples.
II. GENERAL COMMENTS:
The laboratory has been moved into a new room since the last inspection and is clean and well organized.The
facility has all the equipment necessary to perform the analyses. Findings C, G, H, I, and J are new policies
that have been implemented by our program since the last inspection.
Ill. FINDINGS, REQUIREMENTS,COMMENTS AND RECOMMENDATIONS:
General Laboratory
A. Finding: A log of prepared reagents is not maintained.
Requirement: All chemicals, reagents, standards and consurnables used by the laboratory must have
the following information documented: date received, date opened (in use), vendor, lot number, and
expiration date (where specified). A system (e.g., traceable identifiers) must be in place that links
standard/reagent preparation information to analytical batches in which the solutions are used.
Documentation of solution preparation must include the analyst's initials, date of preparation, the
volume or weight of standard(s) used, the solvent and final volume of the solution. This information as
well as the vendor, manufacturer, lot number, and expiration date must be retained for primary
standards, chemicals, reagents, and materials used for a period of five years. Consumable materials
such as pH buffers, lots of pre-made standards and/or media, solids and bacteria filters, etc, are
included in this requirement. Ref: North Carolina Wastewater/ Groundwater Laboratory Certification
Policy.
B. Finding:The analytical balance is not checked with three standard weights quarterly.
Requirement: The analytical balance must be checked with one class S, or equivalent, standard
weight each day used and at least three standard weights quarterly. The values obtained must be
recorded in a log and initialed by the analyst. Ref: 15A NCAC 2H .0805 (a)(7)(K).
C. Finding: Temperature corrections are not posted on the thermometers and/or equipment.

Page 2
#560 Unimin Corporation-Red Hill Plant
Requirement: All thermometers and temperature measuring devices must be checked every twelve
months against a NIST certified or NIST traceable thermometer and the process documented. The
documentation must include the serial number of the NIST certified thermometer or NIST traceable
thermometer that was used in the comparison.Also document any correction that applies(even if zero)
on both the thermometer/meter and on a separate sheet to be filed. Ref: North Carolina
Wastewater/Groundwater Laboratory Certification Policy.
D. Finding: The date chemicals are opened is not documented in the log.
Requirement: Chemicals must be dated when received and when opened. Ref: 15A NCAC 2H .0805
(a) (7) (Q.
Requirement: All analytical records must be available for a period of five years. Ref: 15A NCAC 2H
.0805(a)(7)(G).
Total Residual Chlorine-Standard Methods,20th Edition,4500 Cl G
E. Finding:The daily calibration verification is performed with two standards.
Requirement: For analytical procedures requiring analysis of a series of standards,the concentrations
of these standards must bracket the concentration of the samples analyzed. One of the standards
must have a concentration equal to the laboratory's lower reporting concentration for the parameter
involved. For colorimetric analyses, a series of five standards for a curve prepared annually or
three standards for curves established each day or standards as set forth in the analytical
procedure must be analyzed to establish a standard curve. The curve must be updated as set
forth in the standard procedures, each time the slope changes by more than 10 percent at mid-range,
each time a new stock standard is prepared, or at least every twelve months. Each analyst performing
the analytical procedure must produce a standard curve. Ref: 15A NCAC 2H .0805 (a) (7)(1).
Comment: The blank is not considered one of the calibration verification standards.
Recommendation: A five-point verification may be performed annually rather than a three point daily
verification. In order to bracket the concentrations of both Regulatory and Performance Evaluation
samples, it is recommended that the five verified standards be 20, 30, 50, 200, and 400 pg/L. These
are suggested values and may be modified depending on the glassware available. Expanding the
verification to this range would allow the daily mid-range standard to be 200 pg/L.
Total Suspended Solids -Standard Methods,20th Edition,2540 D
F. Finding: Sample holding times are not always met.
Requirement: All samples must be analyzed within EPA approved holding times. The maximum
holding time for Total Suspended Solids is seven days. Ref: Code of Federal Regulations, Title 40,
Part 136; Federal Register Vol.72, No.47, March 12, 2007.
G. Finding: Filters are not weighed to a constant weight after initial washing, nor is a dry filter blank
analyzed with each set of samples.
Requirement: If pre-prepared filters are not used, the method requires that filters must be weighed
to a constant weight after washing. In lieu of this process, it is acceptable to analyze a single daily
dry filter blank (i.e., no additional rinsing during the analysis). The acceptance criterion for the blank
is a weight change of less than 4% of the filter's initial weight or 0.5 mg, whichever is less. Ref:
North Carolina Wastewater/Groundwater Laboratory Certification Policy based upon Standard
Methods, 20th Edition, 2540 D. (3)(a).

Page 3
r #560 Unimin Corporation-Red Hill Plant
H. Finding:A minimum dried residue weight gain of 1 mg is used to determine the reporting limit.
Requirement: The minimum reporting value is established at 2.5 mg/L when 1000 mL of sample is
analyzed. The minimum weight gain allowed by any approved method is 2.5 mg. In instances where
the weight gain is less than the required 2.5 mg, the value must be reported as less than the
appropriate value based upon the volume used. For example, if 500 mL of sample is analyzed and <
2.5 mg of dried residue is obtained, the value reported would be < 5 mg/L. Ref: North Carolina
Wastewater/Groundwater Laboratory Certification Policy based upon Standard Methods, 20th and 215t
Editions, 2540 D. (3)(b).
Fluoride-Standard Methods,20th Edition,4500 F C
I. Finding: A calibration blank is not analyzed. A calibration verification standard (mid-range) is not
analyzed at the end of the sample run.
Requirement: The calibration blank and mid-range standard must be analyzed initially (i.e., prior to
sample analysis), after every tenth sample and at the end of each sample group to check for carry
over and calibration drift. If either fall outside established quality control acceptance criteria,
corrective action must be taken (e.g., repeating sample determinations since the last acceptable
calibration verification, repeating the initial calibration, etc.). Ref: North Carolina
Wastewater/Groundwater Laboratory Certification Policy based upon Standard Methods, 20th
Edition, 1020 B. (10) (c), 3020 B. (2) (b), and 4020 B. (2).
J. Finding: Matrix spike analyses are not performed.
Requirement: Unless the referenced method states a greater frequency, include one Matrix Spike
(MS) with each sample set (batch — 20 or fewer samples) or on a 5% basis. Prepare the MS from a
reference source different from that used for calibration unless otherwise stated in the method.
Laboratories analyzing less than 20 samples per month must analyze at least one MS each month
samples are analyzed. If MS results are out of control, the results must be qualified or the laboratory
must take corrective action to rectify the effect, use another method,or employ the method of standard
additions. Refer to the method of choice for specific acceptance criteria for the MS until the laboratory
develops or adopts statistically valid, laboratory-specific performance criteria for accuracy. Ref: North
Carolina Wastewater/Groundwater Laboratory Certification Policy.
IV. PAPER TRAIL INVESTIGATION:
No paper trail performed.
V. CONCLUSIONS:
Correcting the above-cited findings and implementing the recommendation will help this lab to produce
quality data and meet certification requirements.The inspector would like to thank the staff for its assistance
during the inspection and data review process. Please respond to all findings.

Dear Persons,
It is my understanding that Unimin, the AV&Kil N-IRT wants to increase the
amount of fluorides and solids the discharge to the Toe River.
As a concerned citizen of Mitchell County I feel they should not be permitted to
do this.
The Toe River is one of our counties most valuable resources. In my opinion
should not be submitted to this increased pollution for several reasons.
One the drought that we have suffered for several years makes our river more
vulnerable to pollution.
Number two, this river is a known trout stream and used for various recreational
purposes. Many people enjoy canoeing, kayaking,fishing and swimming in this
river. We do not need companies to discharge more waste into the river. It would
be nice to let our children and-grandchildren enjoy these activities in the future.
Three'.with our county leaning toward tourism for future economic growth•we
do not need to'take ichance by polluting our most valuable resource,
Also the mining industry is discharging a substantial amount already, Unimin
School House, Feldspar, KT Feldspar, Unimin Crystal and Unimin Min pro,Where
does it stop?
I feel we need public input and a study done by the state to make sure we are
not harming the river in any way prior to issuing permits for more fluorides (HF
Acid) and solids
lids to be discharged.
H.F. Acid, Sulfuric Acid and other chemicals are used by the mining industry.
These Chemicals are.very dangerous and could cause major damage to the river if
accidentally discharged,
From information that myself andother-concerned citizens have gathered The
Unimin Red"Hill Plant is not a.good steward:of the...e nvi:ronm.ent.. Th
ey to
assure the people oi'this'cou'nky that they have the ability,equipment and
knowledge-to deal with these. issues.

10-20-'08 12:22 FROM-NC DIV. AIR QUALITY 9197157175 T-352 P03/03 U-931
J
We ask that no permit be issued.There is enough waste going into our river.
Please do not add more. And please consider the impact that this permit would
have on our future tourism. lust what could it do to our river? As the old saying
states
"Please give a Hoot!! Don't Pollute!!"

Dear Mr..Edwards:
Tn response to the NOV received yesterday that, the ]_Zed, 1-fill-plant (Kermit No.
+NxCU.0;853}F discharge exceeded the maximum daily limit of total suspended'solids, the
number that was reported of 330 lbs. was high because of a faulty, air relief valve which
resulted in a false elevated flow number for that day. The problem was the air relief valve in
the line was not working as it should. We found that the effluent line that runs to the Liver
was getting air locked causing the level at the pan,hall flume to be elevated. The elevated
parshall flume, which is the monitoring device for flow to the river, resulted in reporting
high biased flows, thus resulting in high biased TS.S reported. .Although we cannot
document a correct flow,we believe the actual flow was much closer to the average flow and
the actual TSS discharged was in compliance. As you will see,our TSS concentration was in
our normal range.
I began having an occasional high flow in October. We began to look for the
problem and could not find anything We then began to try and catch the flow meter
recording a high number and still could not find anything I brought in Johnston Inc. in
November 13, 2006 to check our flow meter and found that we were getting an electrical
interference that was causing some flow spikes. We thought this was the end of the
problem but;as you can see every few days there is a high flow day.
Since we can only pump 500 gpm to the plant we then looked for something else
and finally cawght one of the spikes in process. We found that the air relief valve was not
working as it should and the effluent line that runs to the river was getting air locked causing
the level at the parshall flume to be elevated. We found this on January 11ie ordered and
received the new valve on the 19*and installed on January 21". Since that time our flow has
averaged 0.530157 mgd with a high flow day of 0.589140.

Page 2
to-help avoid this problem in the future, in addition to replacing the air relief valve,
l have ordcrcd a transmitter that will send a signal to the operator's computer that will give
us a real time flow number, in gaUons per minure which will male it much easier to see a
deviation in our discharge Flow if you have any questions or require additional information
do not hesitate to contact ine directly.

Authorization:
See Tab 1. SEA 12110 2008
2. Brief Description of the Proposed Proiect:
OSTR CTION RMS
The progressive increase in production at the Red Hill facility WUINAC969in an increase of
waste-water between 1.0 to 1.318 (nominal) MGD. To cater to this increase, it has been
determined that a second emergency containment pond (E-2) is necessary. This is to
insure that in a worst case scenario, all waste water is effectively contained at the plant
site. Pond E-2 is to be constructed adjacent to the existing emergency pond E-1 and is
designed to accept solution flow from pond E-1 in an overflow situation or in the event
pond E-1 is withdrawn from service for maintenance. Incorporated in the pond design is a
pumping station to recycle waste water back into the Red Hill facility. Starting and
stopping of pump is activated by a level switch.
The methods used in location and sizing of pond E-2 are fully described and set forth in
the report prepared by S&ME of Arden, North Carolina and appended hereto.

Subject: ATC Application for Unimin Corporation—Red Hill'Facility LOAN SECTION
NPDES Permit No. NC0085839,Mitchell County,North Carolina
Dear Mr. Blaisdell:
Please find enclosed three (3) copies of an Authorization To Construct (ATC)
Application for modification of Unimin Corporation's Red Hill Facility (NPDES Permit No.
NC0085839) to include an additional e-pond and associated pump. In summary, the
modification consists of installing the new emergency pond adjacent to the existing emergency
pond location requiring only one additional pump to return the effluent back to the WWTP
prior to treatment and discharge to the N.Toe River location.
There will be no changes to the treatment plant processes or the characteristics of the
waste generated. The only changes to be made are the addition of the e-pond and the effluent
return pump. The NPDES Unit is in the process of reviewing and approving the NPDES
Permit to allow additional flow, fluoride and TSS per the design capacity of the future waste
water treatment plant. Per my telephone discussion with Susan Wilson, Supervisor NPDES
Western Region, she stated she will discuss this issue with your Section and recommend that you
go forth with this approval prior to issuance of the new permit. This additional e-pond is
urgently needed due to the existing e-pond full of solids and cannot be cleaned out until another
e-pond is created in order to avoid shutting down the full-time operation.
Please accept this letter of request for an ATC for Unimin's Red Hill Facility to install,the
e-pond and associated pump. As this project is extremely urgent, I am grateful for all efforts you
can make to expedite this ATC approval. If you have any questions regarding this matter or
require further information,please do not hesitate to contact me at [phone] ext. 13.
Sincerely,
J46ey S. Fer/son,P. E.

Attention: Mr. Donnie Niemann
Subject: Report of Engineering Design
E-Pond#2
Red Hill, Madison County, North Carolina
S&ME Project Number 1411-08-042
Dear Mr.'Niemann:
S&ME, Inc. is pleased to provide this report of engineering design for the proposed
E-Pond#2 construction. We have prepared this report in accordance with our proposal
number CIV-045-08, dated March 10, 2008. Herein we discuss our understanding of the
project Purpose, our Methodology for analyses and design, the results of our calculations,
and our design Conclusions.
1. PROJECT INFORMATION
1.1 Purpose of Design
Operational expansions at the Red Hill Facility will increase emergency containment and
storage requirements for excess wastewater. Unimin requested assistance from S&ME,
Inc. in planning and engineering for an additional emergency containment.and storage
pond(E-Pond#2)that would be adjacent to an existing pond(E-Pond#1'). We
understand the proposed pond would generally only be filled when the existing,primary
pond overflowed or was temporarily taken out of service for maintenance. S&ME, Inc.
has provided services to develop design and construction documents for the construction
of the E-Pond#2.
1.2 Design Considerations
The proposed additional emergency containment facility will be constructed adjacent to
the existing emergency containment pond to the north and west. (See Construction
Plans) We sized the pond based on the following constraints:
o Existing access roads to the northwest and southwest.
o The existing containment pond.
o The existing embankment to the southwest of the pond.
S&ME,INC./44 Buck Shoals Road;Unit C-3/Arden, NC 28704/p 828.687.9080 f 828.687.8003/www.smeinc.com

Unimin Corporation—E-Pond#2 SWE Project No. 1411-08-042
Red Hill, North Carolina June 25,2008
o Various process supply and discharge pipelines on the north side of the
proposed site and along the access roads.
o Geotechnical characteristics of the existing site soils related to
embankment stability, seepage, and reuse as structural fill.
o Geotechnical characteristics of the available borrow soils for use as
structural fill and as compacted clay liner.
o Other subsurface conditions at the site, including depth to rock,
groundwater conditions, and the qualities of the existing fill and fill
embankment.
o We have not performed any stormwater runoff calculations for the
proposed E-Pond#2 at the request of Donnie Niemann of Unimin
Corporation. It is our understanding that all stormwater runoff will be
routed around the pond and Unimin will maintain 1-foot of freeboard by
pumping.
Unimin requested we design the new pond to have a compacted clay liner, rather than a
synthetic liner such as was used in the existing pond. Based on information from Mr.
Ken Pohlig of the NC DENR, Construction Grants &Loans Division, through Mr. Jeff
Ferguson of Unimin, a clay liner would be acceptable, with the permeability of the liner
being no greater than 1x10-6 centimeters per second to comply with NC DENR
requirements. Also, this permeability limit is based on bedrock being greater than four
feet below the liner. If bedrock is shallower, the permeability of the liner must be no
greater than 1x10-7 centimeters per second.
2. METHODOLOGY
S&ME, Inc. performed various tasks to develop the construction documents. The tasks
included data review, subsurface exploration, test pit excavation, and laboratory testing of
soils. Based on the results of the explorations and analyses, S&ME, Inc. developed site
grading plans and structural details for the construction of the E-Pond#2. A discussion of
these activities and our methodology follows.
2.1 Data Review and Site Reconnaissance
S&ME, Inc. reviewed available data for the existing emergency containment pond and
site topography which you provided. We also visited the site on several occasions to
observe the existing and proposed pond areas and meet with Unimin personnel.
2.2 Subsurface Exploration
Subsurface conditions in the proposed pond area were evaluated by four soil test borings
and observation of test pit excavations. The boring and test pit locations were established
in the field by our personnel based on existing site features and the topographic site plan
provided to us.
Standard penetration tests (ASTM D-1586) were performed in the borings at 2.5-foot
intervals for the first ten feet of depth and at 5.0-foot depth intervals thereafter. Split-
spoon samples were obtained for visual inspection and classification. The Unified Soil
2

Unimin Corporation—E-Pond#2 S&ME Project No. 1411-08-042
Red Hill, North Carolina June 25,2008
Classification System (USCS) classifications for the samples were estimated using
visual-manual procedures. A bulk sample of the existing fill material in the pond area
_ was also collected for laboratory testing. Groundwater levels were measured upon
completion of the borings.
Boring Logs are included in the Appendix of this report. A boring location plan showing
the approximate boring locations is included as Figure 1 in the Appendix. The elevations
shown on the Boring Logs are approximate, and were interpolated from the topographic
site plan provided to us.
We observed excavation of test pits made with a small tracked excavator at the crest of
the existing embankment adjacent to the proposed pond, as well as in the lower portion of
the embankment face. We visually classified the soils encountered in the test pits, and
evaluated their consistency with a steel probe rod. The test pit results are presented on
Test Pit Data Sheets and the approximate locations are presented on Figure 1 in the
Appendix.
2.3 Evaluation of Borrow Areas for Liner
Two potential borrow sources for the clay liner material were identified and evaluated by
our geotechnical staff. Test pits were excavated in the borrow areas to evaluate the
suitability of the soil for use as a liner material. We visually classified the soils
encountered in the test pits, and collected representative samples for laboratory testing.
The locations of the borrow areas are indicated on project Drawing Sheet 1 of 5. Test pit
results are described later in this report(section 3.3).
S&ME, Inc. performed laboratory soil testing to classify soils at the pond site and the
borrow soils for the liner. We also tested potential liner soils to determine clay content
and permeability. Laboratory testing performed included tests for: Natural moisture
content, Grain size analysis, Atterberg Limits, standard Proctor compaction,permeability,
and specific gravity. A summary of the laboratory test data is included as Table 1 in the
Appendix of this report. The individual laboratory data sheets are also included in the
Appendix.
3. FINDINGS AND RESULTS
3.1 Data Review and Site Reconnaissance
The existing emergency containment pond is approximately 150 feet by 180 feet in plan
dimensions. According to construction plans, it is lined with an 80 mil, high-density
polyethylene geo-synthetic membrane. The working depth of the pond appears to be 5
feet. The overall pond depth is six feet according to construction drawings. The pond is
currently impounding waste water and solids from the plant process and rainwater.
There is an existing fill embankment sloping downward away from the southwest side of
the existing pond and the proposed pond area. The embankment is about 15 to 30 feet
1 high, and is generally inclined at about 2:1 (Horizontal: Vertical) to 1.5:1. (See Drawing
2 of 5 in the Construction Plans).

Red Hill, North Carolina June 25,2008
3.2 Subsurface Exploration in Pond Area
The subsurface conditions described herein have been generalized. Detailed data at each
explored location can be obtained from the individual Boring and Test Pit Logs provided
in the Appendix of this report.
Our exploration indicates the proposed pond area contains some existing fill to depths as
much as 12 feet from the existing ground surface at the time of our exploration. The
existing fill varies in composition, including silty fine sand with rock fragments to sandy
clay, depending on location. The existing fill is underlain by residual soil. The residual
soils underlying the proposed pond are generally low to moderate consistency,brown and
red brown, moist, fine sandy silt and silty fine sand.
The existing embankment to the south and west of the pond area consists of up to about 4
feet of existing fill overlying a natural slope in residual soil. The upper 1 to 3 feet of the
fill on the face of this slope is not well-compacted, and appears to have been unstable in
the past. Portions of the slope face have also been eroded.
3.3 Clay Liner Borrow Areas
Based on visual inspection of the soils in the test pits made in the borrow areas, the upper
2 to 4 feet of soils (below about 4 to 6 inches of grass and topsoil) in both of these borrow
areas appear to have appreciable clay content. These upper soils were observed as red
brown, moist, fine sandy silt and clay. These materials transitioned to silty sands and
sandy silt relatively quickly with increasing depth. These observations were reinforced
by the laboratory test results, which indicate the upper clayey soils are classified as clays
of high and'low plasticity, with USCS group symbols CH and CL,respectively, and as
silt of high plasticity, MH. The laboratory permeability tests indicate these soils have a
permeability ranging from about 3.3 x 10-6 cm/sec to 2.6 x 10-7 cm/sec when remolded to
conditions similar to those anticipated in the field. A summary of laboratory test results
performed on samples from the liner borrow areas can be found in Table 1 in the
Appendix of this report.
4. CONCLUSIONS AND RECOMMENDATIONS
The conclusions and recommendations presented herein are based on information
concerning existing and assumed final grading for the site, our understanding of the
proposed project, findings of the subsurface exploration, geotechnical engineering
evaluations of encountered subsurface conditions, and previous experience with similar
projects.
Based on our exploration, laboratory tests, calculations, and experience,we have
developed construction drawings for E-Pond#2. The construction plans and
specifications are enclosed with this report. We also developed cross sections of the
proposed E-Pond#2 depicting the subsurface profile based on the boring data(see
4

Unimin Corporation—E-Pond#2 S&ME Project No. 1411-08-042
Red Hill, North Carolina June 25,2008
Drawing Sheet 4). We developed details for the reinforced concrete overflow structure
for flows from E-Pond#1 to E-Pond#2 (see Drawing Sheet 5).
4.1 Grading Plans
S&ME, Inc. developed the proposed grading plan for the E-Pond#2 based on the
topographic information provided, and the data obtained from our exploration. The
elevation of E-Pond#2 relative to E-Pond#1 was based on overflow requirements and
other considerations by the Owner. There were a number of other constraints on the
shape and size of the pond as discussed in the Project Information section of this report,
generally due to existing site features.
The proposed pond area has recently been lowered by 5 to 10 feet since our exploration
to near the design elevation for the rim of the pond. This excavation has likely removed
most of the existing fill encountered by the borings. The actual pond excavation is
expected to extend through any remaining fill and into residual soil. The pond
excavation will be about 20 feet deep from original grade, extending down to elevation
2469 feet. The sides of the pond excavation should be sloped no steeper than 2:1 (H:V).
The exposed excavation bottom should be compacted with a sheepsfoot roller and fine
graded prior to construction of the liner.
The crest of the excavation for the new pond will be 15 to 20 feet laterally from the crest
of the existing slope to the south and west. There will be a flat crest between the new and
existing ponds about 20 feet wide on the southeast side of the new pond.
The excavation recently made to lower the pond area has also reduced the height of the
existing embankment south and west of the pond area. The embankment adjacent to the
proposed pond area will require flattening to reduce the risk of slope instability. The
grading plans include flattening this existing embankment to a 2:1 (H:V) or flatter
inclination. As part of this process, the loose existing fill soil on the embankment face
should be removed. The new toe of the slope should be established as needed to achieve
a 2:1 or flatter inclination, and new well-compacted fill placed and compacted in
horizontal lifts starting at the toe. The new fill should be benched into the more stable fill
or residual soils to reduce the risk of sliding along the bottom surface of the new fill. In
some areas it may be more practical to flatten the slope by cutting the top of the slope
back until a 2:1 or flatter inclination is achieved. Some portions of the existing driveway
at the toe of the slope may need to be re-graded as part of this process.
4.2 Compacted Clay Liner
The pond is designed to be constructed with a compacted clay liner using select onsite
materials. The completed liner will be a minimum of 3 feet thick on the bottom and all
sides of the pond. Our design assumptions are based on an effective liner thickness of 2
feet with a permeability of 1 x I e cm/sec. The upper 1 foot of liner is to provide a
buffer and reduce damage of the liner from desiccation (drying), freeze/thaw, roots, or
equipment during dredging or other maintenance.

Unimin Corporation—E-Pond#2 SWE Project No. 1411-08-042
Red Hill, North Carolina June 25,2008
Based on our exploration and the laboratory tests, the identified borrow areas on the
property contain soils suitable for use as a compacted liner. However, these soils are
expected to be limited to the upper 2 to 4 feet of the natural residual soil in the borrow
areas. The excavation of the liner material will require special attention and care. After
removal of the topsoil and root layer, the upper soil can be scraped in successive layers
with a bulldozer, gradually increasing in depth until unsuitable material is encountered.
A representative of S&ME should evaluate the borrow areas during construction. It is
very important that the contractor also has a clear understanding of the types of material
that are acceptable or unacceptable for the liner. Although relatively uniform in
appearance, these soils are not homogenous, as indicated by the variety of USCS
classifications, clay content, compaction characteristics, and other test results on a limited
number of samples. Because of this natural variance in properties, some efforts should be
taken to blend soils from various depths and locations to help achieve a more uniform
liner material. This may be achieved by discing the soil in the borrow area or by
stockpiling and otherwise mixing during the handling process.
During excavation and handling, care will be needed to prevent excessive drying of the
liner soil and formation of hard clods. All clods of soil should be broken down during the
handling or compaction process. If it is determined that clods are remaining intact after
being placed and compacted, then a segregation process will be required to remove large
clods. Rock pieces or fragments larger than 4 inches must be removed.
The liner material should be placed and compacted in horizontal lifts with a sheepsfoot
roller. The lift thickness should be 8 inches or less (loose measure). The soil should be
compacted to at least 95 % of the maximum dry density as determined by the standard
Proctor test(ASTM-D 698). At the time of placement and compaction, the soil should
have a moisture content wet of optimum moisture based on the standard Proctor
compaction test. The acceptable moisture range will be from optimum moisture to 5
percentage points above optimum. The soil may require some moisture adjustment
(drying or wetting) to meet the project specifications.
The liner on the side slopes of the pond also should be constructed in horizontal lifts
starting at the bottom. We recommend constructing the liner on the side slopes wider
than designed, or as wide as required for the compaction equipment, and then cutting it
back to the design dimensions, leaving the face well-compacted.
An experienced Materials Technician under direction of the Engineer should observe fill
placement and compaction. Field and laboratory tests will be required to evaluate the
varying soil types and compaction characteristics.
Additional details on the liner material and construction of the liner are included on the
project drawings (see Sheet 3 of 5).

4.3 Overflow Structure
r
The enclosed drawings include details and plans for the overflow structure from E-Pond
#1 to E-Pond#2. This structure will be constructed of cast-in-place reinforced concrete.
The concrete shall have a compressive strength of 4,000 pounds per square-inch at 28
days after placement. A grate, as requested by Unimin and designed by others, will allow
traffic to cross over it. As requested, the structure was designed such that E-Pond#2 will
only begin to fill after E-Pond#1 is full and overflowing.
4.4 Pond Maintenance
The pond and the clay liner will require some maintenance and long-term monitoring by
the Owner to maintain its design properties. Since it will only periodically be filled, the
clay material could potentially become desiccated and develop large shrinkage cracks
extending partially or entirely through the liner. Severe drying can be reduced by
keeping the pond liner moist by periodic irrigation, or by keeping a small amount of
water in its bottom. Plant roots will also create holes in the liner. If the pond area is to
be vegetated, it should be covered with grass species having shallow roots. Weeds and
other grasses with deeper roots should not be allowed to grow in the pond. Severe
freezes could potentially penetrate a significant depth into the liner and reduce its
permeability. Animals burrowing into the pond liner can also cause damage. Damage
from any of these sources will result in the effective liner permeability being much higher
than intended. A large leak that is not detected and repaired could potentially develop
into slope instability or piping through the surrounding embankments. Periodic
observations of the surrounding embankments should be made to check for wet areas or
other evidence of seepage from the pond.
The embankments outside of the pond should be vegetated promptly to prevent erosion.
Special matting can used to help establish vegetation and reduce erosion. Storm water
should not be allowed to flow over the crest of slopes.

3.4 The pumps will be furnished with rubber lined impellers to meet the normal operating
conditions, but in no instance shall they be larger than 95% of maximum to allow for
possible future retrofits of larger impellers.
3.5 The net positive suction head (NPSH) required based on cold water at rated
conditions shall be selected as follows:
NPSH Available Must Exceed
NPSH Available NPSH Required by at Least
10 feet or fewer 2 feet
10 feet to 15 feet 3 feet

4.2 A heavy-duty cantilever design suitable for handling high specific gravity slurries.
The pump, drive, and motor components shall be assembled into a self-contained
unit which ca be handled as a single module. The assembly shall be fitted with
heavy lifting lugs for easy manipulation.
4.3 The case shall employ a double suction, anti-clog design accommodating a
thrustless, semi-open impeller allowing the pump to run dry continuously without
damage. Bottom and top suction openings shall be protected by slotted, elastomer
covered screens to prevent oversize tramp material from entering the volute. The
volute shall be covered with an abrasion resistant elastomer.
4.4 The pump shall be a dual volute design with integral splitter configured to balance
the radial forces acting on the impeller to minimize shaft deflection at high discharge
head or low flow conditions. Abrasion resistant elastomer covered impellers shall be
molded under high pressure for maximum density and consistency. The impeller
shall be attached to the pump shaft using heavy anti-seize threads.
4.5 Adjustment of impeller running clearances shall be done using a triangular three-
point adjusting mechanism located above the pump base plate and shall be
accomplished without any pump disassembly.
4.6 The bearing housing shall be of cast iron construction and positioned above the
base plate having no submerged bearings, seals, or packing of any kind. The
grease lubricated bearings shall be heavy-duty roller type protected from
contaminates by lip seals and Forsheta v-rings on either end of the housing
assembly.
The bearing assembly shall be further protected from contamination by an
elastomeric flinger located on the pump shaft immediately below the pump base.
The bearing housing shall be sized one size larger than the capacity of the pump.
4.7 All fasteners below the base plate shall be 316 stainless steel.
4.8 The hydraulic-end shall accept a field convertible auger kit with high chrome iron
auger to prevent sanding-in problems. The assembly shall be supported by a rigid
intermediate shaft which does not compromise the impeller attachment system.
4.9 The pump shall have interchangeable mechanical ends of various capacities to
accommodate varying head and flow conditions.
4.10 V-belt driven pumps shall have an integral motor mounting base constructed of
heavy steel plate, slotted to accept standard NEMA frame foot-mounted horizontal
motors and be easily adjusted to maintain proper belt tension. Assembly shall
include a totally enclosed belt guard.
4.11 Discharge pipes shall terminate above the mounting plate, be located by an
adjustable bracket and have through-bolt flange construction.
