- Subject: NPDES Permit Issuance
NPDES Permit NC0000361
Unimin-Schoolhouse Quartz Facility
Avery 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 2.16 MGD of treated
wastewater from the Schoolhouse Quartz 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), settleable solids, turbidity,
pH, chloride, and chronic toxicity.
The request for results of a priority pollutant analyses has been rescinded based on
the information submitted in the facility's NPDES application, Item V-Part B.
The following modifications have been made to the permit:
■ The monthly monitoring requirement for lindane will be removed from the permit
based on the results of a reasonable potential analysis. The lindane data indicated
no potential to exceed the water quality standard. Effluent data submitted
indicated no detections of lindane in the effluent or in upstream samples from
August 2004 through December 2005.
■ The addition of a special condition for turbidity. The condition states that in the
event that violations of the turbidity standard of the North Carolina Water Quality
Standards occur as a result of this discharge, this permit shall be modified, or
alternately, revoked and reissued to incorporate limitations sufficient to protect the
receiving waters. See Special Condition A. (7).
• The addition of effluent limitations and monitoring requirements for mine
dewatering and land disturbing activities. These requirements have been added in .
Section B. Final Limitations and Controls for Stormwater Discharges, Parts (4) and
(5), to ensure that all requirements from Unimin's previous stormwater permit
(NCG020112) are adequately covered in this permit for.the protection of the North
Toe River.

Letter to Mr. Bradley
Page 2
Unimin has requested that quarterly monitoring be included for the mine
dewatering parameters. However, because of the North Toe River's designation as
impaired for turbidity, it is recommended that monthly monitoring remain so that
the impact on the stream from mine dewatering can be consistently evaluated.
The following is a modification from the May 10th draft permit:
• Monthly monitoring for oil and grease will be reduced to quarterly based on
Unimin's informatidn that oil and grease impact should be minimal.
The North Toe River 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 there is noncompliance
with permitted effluent limits and degradation of the North Toe River can be attributed to the
Unimin Corporation WWI? discharge, then removal of the discharge may be necessary. The
Unimin Corporation may determine in the future that an alternative to surface water
discharge may be more appropriate.
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,
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 reissuance 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.
If you have any questions or need additional information, please contact Ms.
Jacquelyn Nowell at telephone number [phone], extension 512.
Sincerely,
W. Xlimek, P.E.

STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED
DISCHARGES
SECTION B. 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 c6vered 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 requitement.of this permit. `

I
NC0000361
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 C: 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 3. All analytical monitoring shall be performed dining a
representative storm event as defined in Section E.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:
,OoAnalytical monitoring for stormwater discharges from a basin or other similar control
structures must be performed within the first 30 minutes of discharge. `

NC0000361
• Analytical monitoring for a basin/pond designed to contain the 10-year design storm(see
Section E.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 E. 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.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
Unimin Corporation is requesting a permit renewal for its Schoolhouse Quartz Operation Plant.
The Schoolhouse Quartz Operation Plant does mining, milling, and separation of Alaskite ore to
produce quartz, feldspar, and mica. 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 discharges from mine dewatering. New stormwater monitoring
requirements for this activity were included in this permit. Outfalls 101 through 116 discharge
stormwater runoff and monitoring requirements for this activity are already included in this
permit. Flow limit is 2.16 MGD
The primary concern is the discharge of fluoride from the quartz and feldspar mines in the
North Toe River. The allowable Fl loading has been allocated out between five mines. The total
pounds per day of fluoride allocated are 574. The goal is to protect water quality while allowing
some flexibility for the dischargers to maintain compliance.
RECEIVING STREAM INFORMATION:
*The North Toe River is not listed on North Carolina's 2004-303(d) list, however it should be
noted that the 2005 French Broad River Basin Management Plan has a segment of the North
Toe River with a use support rating of Impaired based on turbidity and riparian area loss. The
segment also has a bioclassification rating of Fair (It is listed as biologically impaired on the
2006 Draft 303d list).
At this time, DWQ proposes no changes to the previously developed load allocations. Neither
the impairment nor the turbidity violation is directly attributable to the discharges. However,
the facility will be notified via the cover letter about potential impacts due to the Draft 303d
list.
INSTREAM MONITORING:
Upstream: Above the plant intake
Downstream: Franklinton Bridge.
Parameters: Fluoride, Lindane (upstream only), TSS, Turbidity, pH
Data review showed no exceedances of the Fl standard either upstream or downstream of the
Schoolhouse Quartz discharge.
All lindane samples taken above the plant were below the detection level of 0.05 ug/1.
l'nimin Corporation—Schoolhouse Quar z Op erafion Factsheet
NPDES Renewal
Pate 1

Turbidity exceeded the standard of 10 NTU in an upstream sample in September 2004 and the
downstream sample was 9.8 NTU.
In June, July and August 2005, the monthly average turbidity value exceeded the standard
both upstream and downstream of the discharge.
TOXICITY TEST RESULTS:
Quarterly Chronic P/F, 100/6 Ceriodaphnia test. FEB MAY AUG NOV
Facility's compliance with toxicity limit has been good overall. From June 2004 through
December 2005, all toxicity tests were passed.
Recommendation: Renewal of quarterly chronic test 0 10%
REASONABLE POTENTIAL ANALYSIS/EFFLUENT CHARACTERISTICS:
A reasonable potential analysis was done on lindane (Gamma BHC). Permit required monthly
monitoring effective August 2004. Eighteen samples were evaluated from August 2004 through
December 2005 discharge monitoring reports. All data values were below detection level and
showed no potential to exceed the NC water quality standard for lindane. Effluent monitoring
and upstream monitoring of lindane will also be deleted from the permit.
The following parameters are noted in the 2005 application as present in the effluent.
Sulfate, Chloride, Fluoride,Aluminum, and Oil&Grease
Results of pollutant scan, sampled on 8/29/2005
Aluminum = 4.64 mg/1 There is no NC Std , EPA Criteria=750 ug/1, Aluminum is very
prevalent in NC soils and sediment, therefore no limit or monitoring for aluminum is
recommended for NC dischargers.
Sulfate= 740 mg/1 The NC Std applies only to Class WS waters, North Toe River is Class C-
No limit or monitoring for sulfate will be recommended
Chloride believed to be present in the effluent. The NC Action level= 230 mg/1; Allowable cone.
= 2291 mg/1. Chloride is already monitored quarterly in the permit and will be continued.
Fluoride believed to be present in the effluent. The NC Std = 1.8 mg/l: Fluoride is already
limited in the permit and will be continued to be limited..
Oil and Grease believed to be present in the effluent. Monthly monitoring will be added to the
permit.
COMPLIANCE REVIEW:
Facility has been in compliance with all permit limits consistently in 2004 and 2005. No
reported violations since May 2004.
PROPOSED CHANGES:
■ Based on the results of a reasonable potential analysis, the monthly monitoring
requirement for lindane will be removed from the permit. Instream monitoring for
lindane will be dropped.
■ Monthly monitoring for oil and grease will be placed in the permit as it was noted in
the application as being present in the Unimin-Schoolhouse facility's effluent. ;
■ A special condition for turbidity will be added that states: In the event that violations
of the turbidity standard of the North Carolina Water Quality Standards occur as a
result of this discharge, this permit shall be modified, or alternately, revoked and
reissued to incorporate limitations sufficient to protect the receiving waters.
• Effluent limitations and monitoring requirements for mine dewatering and land
disturbing activities. These requirements have been added in Section B. Final
Limitations and Controls for Stormwater Discharges to ensure that all requirements
from Unimin's previous stormwater permit NCG020112 are adequately covered in
this permit for the protection of the North Toe River.

Subject: Comments to Draft NPDES Pern-
Unimin Corporation's Schoolhouse ,/ �L —
Dear Ms. Nowell:
Please note the following comments for the Draft
Corporation's Schoolhouse Quartz Facility, cover letter dat
First, the draft permit cover letter states that the L
Corporation submit the results of an annual priority polls
Based on my telephone discussions with Mr. Charles I _, . Wray
informed to contact Mr. Marshall Hyatt with EPA with regards to the priority pollutant
analysis. Mr. Hyatt agreed that the primary industry "ore mining" listed in Title 40 CFR 122
App. A refers to metal ore mining (40 CFR 440) whereas Unimin's mines are mineral mining
& processing (40 CFR 436), therefore we are not considered one of the primary industries
and are not required to perform the priority pollutant analysis. Mr. Hyatt stated that he
would send Mr. Weaver an email stating that we did not have to perform the priority
pollutant analysis. Evidently Unimin has been inadvertently required to perform the analysis
during past renewals when not required to do so.
Secondly, monthly monitoring of oil and grease is proposed to be placed in the
permit as it was noted as being present in Unimin's effluent. Please note that I checked oil
and grease on the application and noted "possible leaks and drips from mobile equipment"
I made the same note during the last renewal application and did not receive this
requirement. We assumed that ALL facilities with NPDES outfalls could have possible
leaks and drips from mobile equipment, however the majority of applications probably do
not reflect this. We strive to be truthful in completing the application forms and feel that
we are being required to monitor for something that all discharging facilities may have. We
do not object to monitoring for oil and grease as long as this is a standard requirement for
all NPDES permits. However, if this is not the case, we respectfully request that this
requirement be removed from the permit. Required visible monitoring for oil sheen should
be more than satisfactory.

Ms.Jackie Nowell
May 31,2006
Page 2
Finally, monthly monitoring for mine dewatering has been placed back into the
permit. Please note that the General NPDES Permit No. NCG020000 for mining
operations requires only quarterly sampling for mine dewatering,rather than monthly,more
than sufficient to show compliance. Unimin requests that analytical monitoring
requirements for mine dewatering be reduced to quarterly rather than monthly.
Thank you very much for the opportunity to comment on the Draft NPDES
Permit. If you have any questions or require further information, please do not hesitate to
contact me at(828)J�6081.

"The real work of men was hunting meat. The invention of agriculture was a giant step

hunters, artists, warriors, and tamers of horses, we degraded ourselves to what we are
now: clerks, functionaries, laborers, entertainers, processors of information." -

Subject: NPDES Renewal Requests for Unimin Corporation —Crystal,
Quartz/Feldspar, Red Hill,and Schoolhouse Quartz Facilities
NPDES Permit Nos. NC0084620, NC0000175, NC0085839, and NC0000361
Dear Mr. Weaver:
Please accept this letter as a request for renewal of the following NPDES Permits:
Unimin Corporation —Crystal Facility NPDES Permit No. NC0084620
Unimin Corporation —Quartz/Feldspar Facility NPDES No. NC0000175
Unimin Corporation—Red Hill Facility NPDES No. NC0085839,and
Unimin Corporation—Schoolhouse Quartz Facility NPDES No. NC0000361
Enclosed please find one signed original and two copies of the NCDENR Short
Form C for the Crystal and Red Hill facilities and EPA Application Form 2C for the
Quartz/Feldspar and Schoolhouse Quartz facilities. It is my understanding that there are no
fees associated with the renewal requests. There have been no changes to the treatment
plants at any of the facilities since issuance of the latest permits. Please note that samples
taken for both aluminum and sulfates from the Schoolhouse Quartz Facility effluent are
delayed. The results should be received and faxed to your office within 10 days.
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.
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.

s
fir. Charles H. Weaver,Jr.
.1u,gust 29, 2005
Page 2
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.
In addition, Unimin Corporation would like to request that the requirements to
sample lindane monthly contained in the Schoolhouse Quartz NPDES permit, and the
requirements to sample aldrin, heptachlor, lindane, and methoxychlor twice per month
contained in the Quartz/Feldspar NPDES permit be removed.
Hits for these pesticides were shown in the Priority Pollutant Analyses, samples
collected on February 19, 2004 for Quartz/Feldspar and June 19, 2001 for Schoolhouse
Quartz. As previously discussed, pesticides are not used in any process or in any form at
either of the two facilities. We believe the discharge of these pesticides are due to utilizing
the N. Toe River water for process water. As you are aware, Avery County is a major
contributor to the Christmas Tree industry and the storm water runoff containing
pesticides from these Christmas tree farms report to the N. Toe River. A requirement to
sample these pesticides for eighteen months was placed in the NDPES permits issued on
June 23, 2004. Since that time, the following results have been observed.
rb �P� Unimin Schoolhouse has sampled both the effluent and the intake water on a
monthly basis since the permit was issued. No hits have been detected in the intake or
f effluent water.
l
Unimin Quartz/Feldspar has sampled both the effluent and the intake water twice
per month since the permit was issued. Lindane was detected only once on August 13, 2004
with a result of 0.031 ug/1, slightly above the Pace reporting limit of 0.025 ug/l. Heptachlor
has been detected in the effluent on three occasions. The three effluent detections were
0.10 ug/l on September 25, 2004, 0.056 ug/l on September 29, 2004, and 0.041 ug/l on
November 30, 2004. Heptachlor was detected in the intake water on August 20, 2004 with
a result of 0.027 ug/l. The Pace reporting limit for Heptachlor is 0.025 ug/l. No other
detections have been made in the intake or effluent water.

"v(r. Charles H. Weaver,Jr.
_lugus t 29, 200i
Page 2
Please note that pesticide samples taken on April 14, 2004 did not show any
detections, however upon observing the Pace Analytical Services laboratory QC data, the
control sample showed a result of 0.011 ug/l delta-BHC greater than the reporting limit of
0.010 ug/1. This proves that the test is very unreliable at such low levels.
The inclusion of pesticides in the process water effluent can only be from the
intake water taken from the N. Toe River due to such high volumes of Christmas tree farms
in both Avery and Mitchell Counties. Unimin Corporation would like to request that these
requirements to sample pesticides be removed from the NPDES permits.
If you have any questions regarding this matter or require further information,
please do not hesitate to contact me at [phone] ext. 13.

CONTINUED FROM PAGE 3 OF FORM 2-C NC 1001 .
PART C-If you are a primary Industry and this outfall contains process wastewater,refer to Table 2c-2 in the Instructions to determine which of the GCIMS fractions you must test for. Mark"X"in column 2-a for all such GC/MS
fractions that apply to your Industry and for ALL toxic metals,cyanides,and total phenols. If you are not required to mark column 2-a(secondary IndusWes,nonprocess wastewater outfalls.and non-required GCAVS
tractions),mark"X"in column 2-b for each pollutant you know or have reason to believe Is present. Mark"X"In column 2-c for each pollutant you believe Is absent. 9 you mark column 2a for any pollutant,you must
provide the results of at least one analysis for that pollutant. M you mark column 2b for any pollutant,you must provide the results of at least one analysis for that pollutant. If you know or have reason to believe It will be
discharged In concentrations of 10 ppb or greater. If you mark column 2b for amolein,acrylonitrile,2,4 dinkrophenol,or 2-methyl-4,B dinkrophenol,you must provide the results of at least one analysis for each of these
pollutants which you know or have reason to believe that you discharge in concentrations of 100 ppb or greater. Otherwise,for pollutants for which you mark column 2b,you must either submit at least one analysis or
briefly describe the reasons the pollutant is expected to be discharged. Note that there are 7 pages to this part:please review each carefully. Complete one table(all 7 pages)for each outfall. See instructions for
