Dear Mr. Peele:
This is in reference to your application received April 4, 1994 for the construction and operation of
the subject facility.
In conjunction with the site inspection, Mike Parker of the Division of Environmental
Management's Asheville Regional Office asked you to provide a justification of Aspect Minerals' need for
an NPDES surface water discharge permit in light of the fact that you have an operational recycle system in
place. As of today, this information has not been received, therefore, the Division must return your
application and support documents as incomplete in accordance with North Carolina General Statute 143-
215.1. The documents are being forwarded to you under separate cover.
When you have obtained the requested information which is needed to make your application
complete, you may;submit a new application package and permit processing fee.
If you have any questions concerning this matter, please contact Dana J. Bolden at 919/733-5083.
Sincerely,
A. Preston Howard, J ,:=P

Note regarding: NPDES NC0000434
When Fred Deneen (old address: PO Box 124, Micaville, NC
28755) owned this property, he had the following system and
permit:
CLASS_I_TYPE 1.2 MGD wastewater treatment facility consisting of a
pump station, overflow sump and pump, three inorganic
solids settling basins and flow measuring and totalizing
equipment.
FACILITY: Deneen Mica Plant
NC0000434 - issued: 10-1-94 expired: 12-31-96
Location: Intersection of Hwy 19 E and NCSR 1151 near Newdale
Stream: South Toe River, (C-Trout) , French Broad River Basin
Subbasin: 04-03-06
Note: This manufacturing plant shut down all operations
around the end of 1991. The permit has expired.
I spoke with Fred Deneen III on August 19, 1998. He stated that he sold part
of the property to Aspect (now: Zemex) and the other part (the part with the
ponds and NPDES permit NC0000434) to Inmet Mining.
Inmet Mining Company, parent company of: Metall (pronounced "metal") Mining
Corporation of Toronto, Canada, contacted this office 12-1-93. They discussed
obtaining a discharge permit to discharge fluoride-containing wastewater.
They have not applied for an NPDES permit as of this date. Inmet still owns
the property and filled in the three ponds and reclaimed the area in October
of 1997.

PART IV - EVALUATION AND RECOMMENDATIONS
Aspect Minerals, Inc. has made application to discharge 0 . 960 MGD
of wastewater from the processing of ore to produce clay, mica and
sand. Chemical will be added to the process to aid in removing
solids and clay particles from the wastewater. The toxicity group
should evaluate the chemicals to be used to determine if toxicity
requirements should be included in the permit.
Also, I have contacted the company and requested that they justify
the need to discharge wastewater to State surface waters since
they are presently operating with a recirculating nondischarge
system.
All correspondence should be sent to Mr. Ron Peele, President,
Aspect Minerals, Inc. Mr. Greg Woody is no longer with the
company.
It is recommended that the permit be placed on "hold" until we
have resolved this matter.
If you have questions, please call me at 704-251-6208 .

RE: NPDES Permit (A' ('
South Toe River Plant
Yancey County, North Carolina
Dear Mr. Woody:
Engineering & Environmental Science Company has completed the
evaluation of the proposed treatment of wash water for the South
Toe River Plant. This report contains a discussion of the system,
waste water characteristics and other pertinent information.
Submitted with this report are the "Plans and Specifications" .
Following is a brief discussion of the project.
GENERAL DISCUSSION
A NPDES treatment system is proposed at the South Toe River
Facility. This facility is located in Yancey County immediately
north of Hwy 19 (see Figure No. 1 in Attachment A) . This facility
will process ore mined for mica and sand.
This facility was formally known as Deneen Mica Company and the
existing structures will be used for the processing of mica and
sand. When the facility was operated by Deneen Mica Company,
processing was conducted under a NPDES Permit. Water was pumped
from the South toe River to a pond upslope of the facility. The
water then would drain by gravity to the mica processing facility.
The washwater would be pumped to a series of ponds that are located
on the opposite side of the south Toe River. As much as 1 MGD of
water could be . discharged back to the river (see Figure No. 2 in
Attachment A) .
Instead of operation of the plant with the existing NPDES Permit,
a new NPDES Permit is desired with some modifications. Instead of
utilizing the existing settling pond, the washwater will be cleaned
of fine colloidal clay using an Enviroclear thickener and vacuum
drain filter. Also, a containment pad will be constructed to
temporarily store the clay soils until appropriate off-site
disposal.

NPDES Permit
South Toe River Plant
Yancey County, North Carolina
Precipitation runoff from the containment area will be drained to
the upslope source pond which will also be fed water from South Toe
River. This water serves as the source for the plant process.
Diversion ditches will be constructed around the pond to better
control surface water runoff from other areas. Both the source
pond and the containment area will have 1 ft. thick compacted clay
liners with coef. of permeability slower than 1 x 10-7 cm/sec.
Other modifications will include construction of a pipe line and
installation of a pump to transfer the used wash water from the
plant to the clay thickeners. Also, a pipeline will be constructed
from the clay thickeners to South Toe River for gravity discharge.
SYSTEM MATERIAL BALANCE
It is estimated, based on past experience with areas excavated
nearby, that approximately 40 percent of the material will
consist of clay. At maximum production 600 lbs. of ore can be
processed per minute and 240 lbs. of clay will be contained in
the water. For continuous process with three (3) shifts, 432
tons of ore can be processed with 172.8 tons of clay (dry)
produced. Approximately, 960,000 gallons of water will be
treated and discharged daily.
The clay wash water (clay at 4 to 5 percent solids) will be
pumped through a six (6) inch approximately 420 ft. long Schedule
80 pipeline to an Enviroclear Thickener. Prior to entering the
thickener, Nalco 8873 Flocculant will be added at a rate of 0.3
pounds per ton of clay or at approximately 0. 12 lbs. of
flocculant per minute or 51.84 lbs. of flocculant per day (3
shifts) .
The clay is brought to approximately 20 percent solid and then
pumped to a vacuum drum filter where the clay is increased to 60
percent solids. The clay is then temporarily stored in a
containment area inwhich direct contact with precipitation drains
to a surface drain. The surface drain connects to the source
pond by a one ( 1) ft. diameter concrete pipe. The clay will be
appropriately disposed in accordance with DEM and Solid Waste
Management Regulations.
WASHWATER CHARACTERISTICS
In addition to utilizing Nalco 8873 Flocculant during removal of
the clay particles at the Enviroclear Thickener, Nalco 8852
Coagulant and the Nalco 3D4147 products will be used in the
water sorting of the mica, sand and clay (see Attachment C for
I
62

Material Safety Data Sheets) . Based on past operation of this
facility, and other nearby facilities, the water will have BOD, COD
and TOC of less than 10 mg/1 due to the small quantities of
material used. The Total Solids in the water after treatment will
be no more than 50 mg/l. The Nalco produces will generally adhere
to the clay particles and will be removed with the clay.
SYSTEM EVALUATION
The evaluation of the system includes those areas of the existing
plant that require modifications. More than likely there will be
other plant modifications, since this plant has not been in
operation for nearly two (2) years and several existing plant
components may not be repaired. As these modifications become
apparent, as-built drawings and design evaluations will be
provided. Following is a brief discussion of these evaluations
with any needed design calculation provided in the Attachments.
Pond
The pond will 'serve as a, constant supply of water to the plant.
On January 20, 1994, the spot evaluations of the pond were taken
with a level, and distances were conducted with a tape. Based on
these measurements, the pond has an average depth of 7.5 ft. and
a volume of approximately 472,060 gallons. Minor pond
modifications will include stabilization of the water inlet area
of the pond and plugging the overflow pipe that discharges
directly to South Toe River. If the pond does not have adequate
low permeable soils, a new soil clay liner system also will need
to be constructed for the pond. In-place testing can be
conducted to verify soil permeability adequacy. At least 1 ft.
of the pond's surficial soil should have a coefficient of
permeability of the 1 x 10-7 cm./sec. or slower.
Approximately five (5) acres of upslope land presently drain to
the pond. To ensure a non-discharge recirculation system,
perimeter ditches will be constructed to pass at least the 50-
year rain event around the pond. The west ditch will be a
grassed trapezoidal channel while the east ditch will be v-shaped
and lined with Class A Erosion Control Stone. Attachment D
contains the ditch design calculations.

Pump and Pipe Lines
A new pump and approximately 420 lineal feet of new pipe line will
be required to take the process water from the plant to the clay
thickener system. The pipe will consist of a 6-inch diameter
Schedule 80 PVC. At a flow rate of 700 gpm and an elevation head
of 85 ft. , the total dynamic system head will be 99.0 ft.
Attachment E contains the system head calculations.
From the clay thickeners, a new pipe line will be constructed to
the South Toe River. Six (6) inch diameter PVC Pipe will be used.
Clay Thickener System
The clay thickener system will consist of an Enviroclear Thickener
and a vacuum drum filter. In evaluation of. the effectiveness of
this system, the laboratory report prepared by Mr. Gary L. Nelson
and dated February 24, 1987, was used. The ore used for these
evaluations will be the same source as for the South Toe River
Plant.
The laboratory tests indicated scale-up rates of 2.5 to 3.5
gpm/ft.2 for the Enviroclear thickener. At a flow rate of 700 gpm,
the diameter of the thickener will need to be at least 20 ft.
Addition of 0.3 lbs. of flocculent per one (1) ton of dry clay soil
will be required.
The vacuum drum filter 'was based on the Buchner funnel test
performed by Mr. Nelson. At a vacuum of 20 to 25 inches of
mercury, submergence of 30%, and a clay load rate of 240 lbs./mina ,
the surface area of the drum will need to be at lest 1, 100 ft.2.
It is estimated that the clay solid will be 60% after treatment.
The calculations are contained in Attachment F. Attachment F also
I contains a general schematic of the Enviroclear system.
Containment .Area
The clay thickener system and temporary storage of the clay will be
within a 50 ft. by 100 ft. pad having a 1 ft. soil liner with a
coefficient of permeability of at least 1 x 10-7 cm./sec. Perimeter
berms will be constructed around the containment system to divert
upslope runoff around the containment area, and to collect direct
precipitation in the containment area.

TITLE:
Mica Project - Clay Process Verification and Optimization
Background and Scope:
The proposed mica plant to be constructed at King' s Moun-
tain, North Carolina , will require a dewatering process for han-
dling the clay fraction by-product. The primary equipment
required for the process will include a high capacity thickener
and a filter for solids concentration.
It was necessary for the clay thickening and filtration
processes be evaluated in the pilot plant for equipment and proc-
ess verification, optimization, and scale-up. A 3 .5 inch diam-
eter Enviroclear high capacity thickener was provided by Mr.
Archie Brumfield of -M. S . French Company , Inc . , Palmetto, Flo-
rida, to evaluate the thickening process . A laboratory Buchner
funnel was used to evaluate the filtration process .
Summary
Utilizing a 3 . 5 inch diameter Enviroclear high capacity
thickener and Nalco 8873 polymer to set�le a representative clay
slurry, scale-up rates of 2 .5-3 . 5 gpm/ft were achieved. Using
the assumed plant production rates , a high capacity thickener di-
ameter of 35 feet would be required with a polymer dosage re-
quirement of 0 . 3 pounds per ton . The project allows for a 60
foot diameter thickener and a polymer dosage requirement of 0 . 33
pounds per ton.
A filtration rate of 58 . 9 lb/hr/ft2 was calculated from
data using a 12 . 5 CM diameter Buchner funnel and 10 cfm filter
cloth. Based on the assumed plant production rates , approxi-
mately 564 ft2 of filtration area would be required. The project
allows for over 600 ft of area.
1

Procedure and Results:
Two 55-gallon drums of clay were received from North Caro-
lina--one from KMG Minerals located in King ' s Mountain and one
from Deneen Mica Company located near Micaville. The Deneen Mica
sample contained slurry produced from the tolling of ore from J.
M. Huber ' s King' s Mountain reserves and represented clay" benefi-
ciated from shallow excavations (less than 40 feet of depth) .
The KMG Minerals sample contained slurry produced from their own
ore mined from depths probably exceeding 40 feet.
The 3 . 5 inch diameter. Enviroclear high capacity thickener
was set-up, demonstrated, and then left with the pilot plant for
a two week period by Mr. Brumfield to allow for extensive trials.
A schematic of the Enviroclear unit is shown in Figure I . Peris-
taltic pumps were used for motoring all streams . Nalco 8873 po-
lymer was used in solutions of 0 . 05-0 . 1%. as a flocculent settling
aid.
A series of trials were performed using each clay slurry.
Each trial consisted of selecting a desired slurry feed rate , op-
timizing the polymer dosage rate to achieve a stable floc , and
achieving a consistent bed level in the thickener by pumping the
underflow at a steady rate . Once this was accomplished, all per-
tinent flow rates were recorded and samples taken to determine
solids content . Results from the various trail are shown in Ta-
ble I . The value pertinent to scale-up, gp5/ft was computed
based on the correlation that one gpm/ft is equal to each 250
ml/min of feed rate . The results indicated a throughput range of
2 . 5-3 . 5 gpm/ft2could be used for scale-up. From this value,
based on projected clay production, a required thickener size of
35 feet is diameter was calculated.
The polymer dosage requirements was calculated at 0 .3
pounds per ton of clay based on average data from the trials .
Calculations to support these results are shown in Appendix I .
Filtration requirements for the project were determined by
filtering clay underflow from the thickener thru a 12 . 5 CM diam-
eter Buchner funnel using 10 cfm filter .cloth. Several trials
were conducted on both clay slurries adjusting process variables
to optimize the rate . The results from the trials are shown in
Table II . Trials 1-8 were used to determine the optimum feed
slurry batch quantity of 200 ml. Trials 9-14 were used to deter-
mine the optimum filtration time of 120 seconds . Trials 15-20
were used to determine the average cake solids for each clay.
The fina results were used to calculate a filtration rate of �5
lb/hr/ft requiring a filtration area of approximately 563 . E ft .
The calculations are shown in Appendix 11 .

d = 32 Ft
. 35 Ft Diameter Thickener is Acceptable
* Conservative value (rate is high) since 15 . 5 TPH at an
average % 5 solids (0 . 431 lb/gal) would equal 1200 GPM.
Polymer Dosage Requirements :
Assume 15 . 5 TPH Feed Rate at 5% Solids (1200 GPM)
Assume Polymer Dosage at 7 . 5 PPM (Nalco 8873 = 8 . 6 lb/gal)
7 . 5 PPM = 0 . 009 GPM
0 . 009 GPM x 60 min/hr x 8 . 6 lb/gal = 4 . 644 lb/hr
4 . 644 lb/hr
= 0 .3 lb/ton Polymer Requirement
15 . 5 ton/hr
