Dear Sirs,
The Feldspar Corporation, by this correspondence, requests approval of the. attached
Authorization to Construct (ATC). The authorization to construct will allow The
Feldspar Corporation to upgrade the Spruce Pine..processing..plants wastewater -treatment
facilities.
The ATC requests the addition of major... components:_. (.1)..A.duel pumping..system with
stand-by generator; (2) The addition of a Clarifier / Thickener (Eimco E-CAT) for
improved clarification and solids handling capacity.
Pump System with Stand-by Generator
Wastewater (tailings) from Plant No. 1 flows by gravity. to. a. tank (commonly known as
the tailings tank) located near the North Toe River. The wastewater is then pumped from
this collection tank to the wastewater treatment plant_ _A.failure of the existing

ATCRequestLetter
pumping system (mechanical, electrical, etc.) has the potential to release wastewater to
the North Toe River. This system was built in 1960 as part of a solids collection system
to prevent the plant effluent from being. -straight -piped -to. the. stream.
To provide a working system,that represents the best available control technology will
requires the addition of a second pump with.the_.ability. to. supply alternate electrical
power to the pumping system. Electrical power failures are the most likely contributor to.
a potential spill. Plant No. 1 has the potential -to -generate 1800 gallons of wastewater per
minute and, because the system is gravity fed, drainage from the plant can continue after
the pump has stopped. Sensors will automatically. activate the stand-by generator in the
event of a power failure or if the wastewater level rises in the tank for any reason.
Alarms will alert the plant operator if the.stand.-_hy.generator is activated. The alarm will
also be indicated on a PC located in the wastewater treatment plant operations room.
Plant operators will be able to open and..close..valves,..start and stop pump motors, and test
the generator from the operations room.
The duel pump set-up is to provide redundancy to assure adequate pumping capacities of
the flows expected from Plant No. 1 under all circumstances, as well as facilitate pump
maintenance.
Addition of Clarifier / Thickener
The original wastewater plant was constructed in the 1960's. and subsequently expanded
with evolving permit requirements, laws, regulations, and production demands. This
worked very well until an upgrade of our No. l.. plantpravided. a sharp increase,ia`
production tonnages and use of feedstock. Two years ago our engineering groupsbegan�
looking into how we could effectively increase. the.. capacity of our wastewater treatment
facility. Due to the location of our plants, Altapass Road and the North Toe River, the
first obstacle to overcome was the placement of_the..additional clarifier.

ATCRequestLetter
After researching the location of the new equipment, we were faced with finding a
wastewater treatment unit that would fit in a very small footprint. We found through
research that Eimco (a division of Baker Hughes) had bought the rights to a South
African patented treatment system that combines thickening and clarification. This unit
is known as the Eimco — Clarifier and Thickener (E-CAT). Eighty-two units are now
operating in six countries with excellent results. The E-CAT has the benefits of a high
rate thickener with a footprint 10% the size of a conventional clarifier, making it the
perfect fit for our needs.
In the spring of 1998 Eimco and The Feldspar Corporation performed a series of pilot
plant test at The Feldspar Corporation's Spruce Pine Facility. This was the first study
performed in the United States and Gerrit du Plessis,..Eimco.'s.E-CAT expert was flown
in from South Africa to conduct the test. After operating the pilot plant for eight days,
the desired results were achieved. In the Fall of 2000,..I.was..able to observe the potential
of the E-CAT during a visit to Val D'or, Canada, where Agnico-Eagle, a gold mining and
refining facility has 6 E-CATS in use. They needed. six.120'diameter conventional
clarifiers to treat the waste streams and chose the six E-CATs for their footprint. We
talked with other facilities that have E-CATs and. they all stated that the E-CAT is
working above and beyond their expectations. Based on the good pilot plant results here
and the favorable experience of those who..have.recently employed this technology we
are now ready to place a 10-meter E-CAT into operation at the Spruce Pine facility.
Construction activities to be covered by the..ATC as. pertains to the placing of the E-CAT
are as follows:
Construction of the E-CAT
Construction of the associated collection and distribution boxes
Construction of the associated pumping and piping
Connecting and interfacing with existing system
Electrical service, distribution and instrumentation

ATC Request Letter
Please find attached the information and related.materials. necessary for your approval of
our request for Authorization to Construct. This modification of our facility should
provide adequate treatment capabilities for years -to come.... We await you approval to
proceed.

CONSTRUCTION SEQUENCE PLAN
Both the placement of a second pump and. the.. construction-of..the Eimco E-CAT clarifier
are add-ons to the present system and are not expected cause any interruptions in
operations.
The collection tank near the river will be upgraded.by_.adding_a.back-up pump and a
stand-by generator as follows:
• Apply to Water Quality section for Authorization.to. Construct and receive
approval.
• The pump house will be enlarged.to...accommodate..the_secondary pump by
pouring a concrete floor in the expansion area. The wood frame building will
them be expanded.
• The new 8X8 ASH (Allen Sherman-Hofl)...slurry_.pump_(pump no.. 2),. supplied
with a 100 HP motor will be installed.
• Pump no. 2 supply line from the tank wilthe..added_.along..with the..automated
valve and plumbed to the new pump.
• The discharge of pump no.2 will be plumhed_into..the_existing piping.leading to
the wastewater plant and supplied with an automated valve.
• The original pump (pump no. 1) will be..fitted-with_automated valves. and new
lines and readied for service.
• Final electrical hook-up to the new automated -switches,. valves, and. stand by
generator will complete this part of the project.
The construction of the building will be done as weather. permits and the equipment and
electrical hook-ups will be made on repair days. We have historically shut all operations
down on Mondays (or Tuesdays) of each week for repairs. that cannot be made while the
plant is in operation. This allows for repairs and -installation of major equipment and
electrical components such as the ones discussed. above-.

The construction of the Eimco E-CAT will -be -scheduled -as -follows:
• Apply to Water Quality section for Authorization to Construct and receive
approval.
• Order E-Cat from Eimco and issue purchase.
• Prepare area for E-CAT concrete_footerjoundation .and. associated.splitter box

Subject: Feldspar Corporation conventional thnckener/clarifier tests
Two settling tests were conducted using the Feldspar Corporation tailings sample at the
conditions used in ECAT pilot test number 6 by Gerritt Du Plessis. These laboratory tests used a
feed solids concentration of approximately 2.5 weight percent (cot°/a) solids and flocculant
dosages of approximately 10 and 12 gram per metric tonne (g/t), (0.024 and 0.03 lbhon)
respectively, of Percol 406 and Percol 336. Respective flocculant concentrations were 0.02 and
0.025 wt% for the P-406 and P336. The cationic P-406 was added first, stirred for 10 seconds,
then the anionic P-336 was added, and stirred vigorously for 10 seconds. Equal volumes of each
flocculant were used -in each test, yielding a 1.25:1 ratio -of anionic to cationic flocculant, usage.
Percol 408 was used in the SCAT pilot tests conducted at Feldspar Corp., but Percol 406 was the
closest substitute available to conduct these two settling tests.
In the first test using 2000 mL of slurry, the free settling velocity measured was approximately 71
mlh, with 20 pprn suspended solids in the supernatant after 10 minutes. After only one,minute,
the supernatant suspended solids measured 22 ppm. In the second test, two 15 liter batches of
slurry were flocculated, decanted, and transferred to a 2 liter cylinder to record dewatet ing and
solids compaction. Ultimate underflow solids concentration contained 62 wt% solids, with
minimal compaction occurring after the first hour.
According to the EIMCO sizing program with this estimated solids concentration, the corrected
unit area'required for this material is 0.11 square foot per ton per day for a 56 wt% solids
underflow. This calculates'to a 92 foot diameter thickener required to process 31 tons per hour.
solids. The feedwell configuration would require a special reactor/clarifier type design to provide
the required mixing needed after adding the second (anionic) flocculant. An in -be mixer would
be required for the feed line prior to entering the thickener to disperse the first (cationic)
flocculent. A clarifier drive would not have sufficient torque to handle the 55 wt% underfloor
solids concentration desired by Feldspar Corporation.

Efficiency In Action: The E-Cat
Operating Process
Slurry entering the E-CAT unit is piped to
the feedwell where it is contacted with
flocculent and clarified liquor from the liquid
recycle column. Influent turbulence provides
ample mixing energy for feed dilution and
flocculation. Solid particles agglomerate
rapidly and begin settling toward the sludge
cone. Here, the weight of accumulated
solids concentrated in a deep, narrow cone
provides maximum gravity compression and
dewatering. Free water displaced from the
solids bed escapes via the dewatering
cones, enters the recycle column and is
returned to the feedwell for influent dilution.
The remaining liquor is channeled through
the clarifying cylinders. Once in the cylin-
ders, fine solids suspended in the upflow
collide and agglomerate, gaining sufficient
weight to settle against the upward liquid
velocity. This solids -contact polishing action
allows E-CAT Clarifier -Thickeners to achieve
low effluent turbidities while consistently
discharging dense, high -quality underflow.

E CAT Pilot Plant Test Work Report
Synopsis
Eimco Salt Lake City was contacted by The Feldspar Corporation about the clarification of a
Feldspar effluent stream. This application involves the clarification of the stream with an E-
Cat ultra high rate thickener/clarifier with organic polymer addition. The overflow clarity
standard limit is 50 mg/1 suspended solids concentration. No underflow density requirments
have been supplied. Eimco proposed pilot plant test work whereby certain parameters are
determined to size a full scale E-Cat for the application.
Laboratory test work was conducted on a sample that was obtained from the stream to
visualise the settling characteristics of the solids in the effluent stream. However to.size the
full scale E-Cat, more accurate and reliable information is required as no information about
the clarification of a Feldspar effluent stream with an E-Cat has been obtained before. This
led to the pilot plant test trials.
The pilot plant test trial was done over a period of nine days, which include pilot plant
assembly and eight days test work.

Introduction
The flow diagram of the Feldspar effluent stream is as follows: The stream originates from
Plant No 1 and No 2 where the Feldspar is concentrated and extracted by a flotation process.
The residual stream is stripped from solids at Plant No 1 and No 2 where a cationic polymer
is dosed into the stream. Thereafter the stream is pumped to the Filter Plant into a distribution
box. An anionic polymer is dosed into this distribution box whereafter the stream is divided
into two streams. One stream is gravitated into a 35-feet diameter conventional clarifier and
the overflow reports to the overflow weir into the river. The underflow is pumped to a
rotating disk filter for the dewatering and disposal of residual solids at the tailing dumpsite.
The second stream is gravitated into a 40-feet diameter conventional clarifier and the
overflow reports back to the plant as recycled water. The underflow follows the same root as
the 35-feet diameter clarifier underflow.
The application for the E-Cat is to replace -the existing clarifiers as they are limited to handle
the existing stream capacity and also the increase in the throughput of the process will
increase the effluent stream capacity and therefore needs to be compensated for.
The E-Cat pilot plant was erected next to the Filter Plant building in order to gravitate the
feed stream from the feed line into the E-Cat pilot plant. A sump with a sump pump facility
was used for the disposal of the underflow and overflow.
The E-Cat is an ultra high rate.thickener and clarifier with low capital, maintenance and
operating costs. A much smaller footprint area is required compared to conventional
thickeners/clarifiers.
Objectives of the test trials
1. To test the pilot plant at optimum conditions.
2. To test variations in the stream over a time period.
3. To determine parameters of the pilot plant at optimum conditions.
The following parameters were optimised during the test trials: Feed flow rate
Flocculant addition rate
Overflow clarity
' Underflow Density

Discussion
Test 1- Clarification of the Feldspar Effluent Stream -No solids stripped, (Anionic Percol
336 Cone. 0.043% m/v)
The test trial objective was to determine the optimum conditions to clarify the Feldspar
effluent stream in order to provide a clear overflow that either report to the river or recycle
back to the plant and thicken the underflow which report to the rotating disk filters. The test
trial was done over a period of 6-7 hours. The stream contains residual Feldspar and associate
minerals.
During this test the feed stream flow rate and polymer dosage rate were varied and the
underflow density and overflow clarity were monitored. The polymer added was Percol 336,
an anionic polymer, and it provided a clear supernatant but a layer of scum formed on the
surface and it was drown into the overflow launder. This resulted in a high concentration. of
suspended solids in the overflow. The polymer used in the pilot plant test trial is also used in
the conventional clarifiers/thickeners and has a concentration of 0.043% m/v.
Test 2- Clarification of the Feldspar Effluent Stream -No solids stripped, Inline static
mixer (Anionic Percol 336 Cone. 0.050% m/v)
The test trial objective was to improve the overflow clarity of the E-Cat pilot plant. The test
trial was done over a period of 3 hours. An anionic polymer, Percol 336, was prepared fresh
with a concentration of 0.05% m/v. An inline static mixer was used to distribute the polymer
evenly in the feed stream. The feed flow rate and the polymer addition rate were varied. The
overflow clarity and underflow density was monitored. The overflow clarity improved with
less polymer addition but it still contained too much suspended solids in the overflow.
Test 3- Clarification of the Feldspar Effluent Stream -No solids stripped, 2 Inline static
mixers (Anionic Percol 336 Cone. 0.050% m/v, Cationic Percol 408
Cone. 2.0% m/v)
The test trial objective was to improve the overflow clarity of the E-Cat pilot plant and to
monitor the effect of using a cationic polymer as a preconditioned reagent. This test trial was
done over a period of 3 hours. The Cationic polymer, Percol 408, was added before the
anionic polymer into the feed line with an inline static mixer to provide even distribution of
polymer in the feed stream. The overflow clarity did not improve but the layer of scum that
formed on the surface' disappeared. The reason for this occurrence is that the colloidal
particles agglomerated before air bubbles attached themselves to the particles and therefore
settled faster than the up flow of the liquid.

Test 4- Clarification of the Feldspar Effluent Stream -No solids stripped, 2 Inline static
mixers (Anionic Percol 336 Cone. 0.025% m/v, Cationic Percol 408
Cone. 0.2% m/v)
The objective of this test trial was to improve the overflow clarity to acceptable
environmental standards. This test trial was done over a period of 7-8 hours. The feed stream
flow rate was varied to obtain lowest possible concentration of suspended solids in the
overflow. The cationic polymer was diluted a 100 times to obtain a more uniform addition of
polymer. The overflow clarity was improved to less than 100 mg/1 but not consistently. The
recommendation for this application would be to use the E-Cat as a primary
clarifier/thickener with a secondary clarifier as a polisher to clear the effluent. A second
alternative would be to use the E-Cat as a clarifier/thickener without second stage treatment
and use the overflow as process water in the various plants.
Test 5&6- Clarification of the Feldspar Effluent Stream- Solids stripped, Two stage
Cationic polymer addition, 2 Inline static mixers (Anionic Percol 336
Cone. 0.025% m/v, Cationic Percol 408 Cone. 0.2% m/v)
The objective of the two test trials was to clarify and thicken'the Feldspar effluent to
acceptable environmental standards. The test trials were done in 2 days over a period of 10-
11 hours. This stream has been stripped from solids and the cationic polymer, Percol 408, has
been added before it was pumped into the "E-Cat pilot plant. The feed stream flow rate was
controlled and the anionic polymer addition rate was decreased. A secondary cationic
Polymer addition point was used to coagulate the solids as the shearing of flocculated solids
was suspected because of energy in the form of turbulence generated in the distribution box.
The concentration of suspended solids in the overflow was monitored at approximately 50
mg/1 and these results were achieved consistently during the two days test trial.

Conclusion
The results obtained from test trials 1-4 indicate that the stream is difficult to clarify but with
proper preconditioning the results might improve. By testing this stream (high solids
concentration), valuable information was obtained about the pre-treatment of the stream to
obtain optimum flocculation and settlement of solids. However this stream was not treated by
the existing clarifier/thickeners and the performance of the E-Cat can therefore not be
compared to the performance of the existing 35- and 40- feet conventional
clarifier/thickeners..
The results obtained from test trial 5&6 indicate that The E-Cat will clarify and thicken the
Feldspar effluent stream (low concentration of solids) to at least the same quality as achieved
by the E-Cat pilot plant.
The test results obtained from the E-Cat Pilot Plant is considered to be accurate and reliable
as the Pilot Plant is a small scale E-Cat and the stream was tested over an eight day period,
where any variations in the stream characteristics were accounted for.

3.0 TECHNICAL DISCUSSION: "WHAT DOES THE E-CATTM CLARIFIER THICKENER
DO?"
3.1 FLOCCULATION & FEED
The E-CATrm Clarifier Thickener is designed to separate solids from liquids at high feed rates.
The fine portion of the feed stream is generally the limiting factor in most thickening and
clarification applications. This is also true with the E-CAT"m Clarifier Thickener. Proper dilution
of the feed to an optimum concentration for the most efficient use of the polymer, is the target.
This dilution level is determined initially through lab scale test work, where the optimum feed
concentration to polymer ratio is established. Initial flocculant selection for use in the E-CAT"m
Clarifier Thickener is made by using conventional jar testing. Pilot plant trials are
recommended for confirmation in difficult or unusual applications.
The feed stream to the E-CATrm Clarifier Thickener enters the feedwell where it is diluted by
the rising clear water from the dewatering cones. See Figure 3, "Flow Pattern Inside The E-
CATTm Clarifier Thickener". The feed may be gravity fed or pumped. The feed suspension,
which may be a thick slurry or a liquid containing a .few parts per million suspended solids,
enters the feed/mixing well via the inlet nozzle. Flocculant is normally added in, either before
the suspension reaches the E-CATT" Clarifier Thickener, or in the feed/mixing well. In most
cases hydraulic mixing, due to the energy of the feed stream entering the feedwell, is sufficient
for the dispersion of the flocculant in the feed stream. Large stones and heavy objects pass
directly into the bottom cone to be discharged.
Proper dilution and flocculation is vital to the success of the E-CATTm Clarifier Thickener. If it
appears that there is insufficient water from the dewatering cones for proper dilution then the
installation of the EIMCO E-DUC® feed dilution system may be employed to achieve the
desired dilution level. These are, in a sense, independent since the dewatering cones rely
upon the potential energy in the solids, in the feed, to "pump" water to the top of the E-CATrm
Clarifier Thickener through .the dewatering tube, while the E-DUC feed dilution system uses the
kinetic energy in the feed to draw in clear water from above the clarifying cylinders. This would
generally occur only on minerals applications where the incoming feed solids concentration is
very high. See Figure 4. "E-DUC Feed Option". Figure 5 "Effect of Feed Concentration"
illustrates the effect of feed solids concentration in the feedwell on flocculant consumption.

3.2 CLARIFICATION IN THE E CATr' CLARIFIER THICKENER
Clarification within the E-CATIm Clarifier Thickener is a new and novel approach. It is
accomplished in "clarifying cylinders".
The clarifying cylinders are arranged in one or more rings around the feed/mixing well and are
generally of circular cross section, or may be formed by baffles between the feed/mixing well
and outer wall of the tank. In this case the cylinders are segmental in cross-section. The
clarifying cylinders, over their operating length, have their longitudinal axes vertical and the
ratio length/diameter is usually between 2 and 8. The cylinders are of constant cross section
along their operating length and are open top and bottom.
As can be seen from Figure 3, the feed suspension enters through the inlet pipe and then
passes downwards into the body of the clarifier/thickener. The thickened solids, at a controlled
density, are withdrawn through the sludge outlet in the bottom cone. The only other exit is
through the overflow nozzle and to reach it, the suspension has to pass upwardly, through the
clarifying cylinders.
Initially, upon entering the bottom of the cylinders, the solids in suspension are in the form of
discrete particles or small flocs. Since these have low settling velocities they will mostly be
carried up by the flow of the suspension entering the cylinders. Inside the cylinders the
movement of the liquid past the flocs imparts energy to the flocs, through the shear forces
acting on the flocs. This results in a drop in pressure in the liquid as it passes upward.through
the cylinders.
This pressure drop multiplied by the cross sectional area of the cylinders can be equated to the
submerged mass of the suspended solids multiplied by (g), the acceleration due to gravity.
This force multiplied by the upward velocity of the liquid in the cylinders, and divided
by the mass of the suspended solids, represents the ortho-kinetic energy input into the
suspension per kg of solids in the feed.
Repeated collisions between particles and flocs cause the flocs to increase in size and, under
the correct conditions, in density. These large flocs will have higher settling velocities which

means that they slow down in the upflow conditions within the cylinders. Eventually they
become sufficiently large and dense to drop down against the flow, ultimately to exit from the
lower, open ends of the cylinders.
Experimental evidence and theoretical analysis shows that, in spite of the random particle
motion within the cylinders, a floc bed is formed inside the cylinders with a distinct top surface.
Flocs within the floc bed are subject to hindered settling conditions, i.e. their apparent settling
velocities are low. Any floc which is "blown out" from the floc bed regains its free settling
velocity, which is considerably higher than its hindered settling velocity. This means that the
floc will settle back into the bed. The liquid above the interface surface is almost free from
suspended solids, while below this surface the solids are fairly uniformly distributed by, and
subject to random motion, until the flocs become large and dense enough to drop out of the
cylinders.
An increase in flow rate causes an increase in the height of the floc bed, and an increase in the
ortho-kinetic energy input. This increase in the energy input, combined with the greater depth
of the floc bed, results in the formation of larger flocs with settling velocities sufficiently high to
enable them to exit from the lower open ends of the cylinders.
A higher feed suspended solids concentration results in a greater pressure drop, a higher
orthokinetic energy input, and the more rapid floc formation and exit rate needed to balance
the increased solids feed rate.
The cylinders can thus operate over a wide range of feed flow rates and concentrations.
The cross section of each cylinder is kept constant over the majority of its length. This
produces steady, but random motion within the floc bed, and maintains an even top surface to
the floc bed. This minimizes the break through of flocs into the clear liquid above the floc bed.
Energy for ortho-kinetic flocculation is derived from the flow of liquid past the flocs in the floc
beds, inside the cylinders. At start up these floc beds have not yet formed and there is the
danger that particles may pass directly through the clarifying cylinders. To overcome this
problem, the cylinders are molded with a small internal lip around the entrance to each
10

cylinder. This not only stiffens the cylinders, but provides a region of turbulence within the
cylinders providing the start up energy for ortho-kinetic flocculation.
Since the lower outlets from the cylinders are open, blockages are eliminated. This can be of
key importance when the feed contains very large solids, or when the flocs can become large
and sticky (due to overdosing of flocculants).
The average upflow velocity in the clarifying. cylinders can be calculated directly from the
difference between the feed flow rate, and the underflow withdrawal rate, since all the liquid
overflowing the clarifier or thickener flows up through the clarifying cylinders.
The flow rates through each clarifying cylinder within a settler, clarifier, or thickener are
equalized, at least to some extent, by the system itself. The reasoning is that all the clarifying
cylinders discharge into a common clarified liquor zone, or well. The outlet pressure is
therefore the same for all the cylinders. All the clarifying cylinders are fed from a common feed
zone. This means the pressure drop across each cylinder must be the same. The geometry
of each cylinder is identical; therefore, losses due to wall friction are the same, and are very
low. Therefore, under equilibrium conditions, the head loss in each cylinder by fluid shear on
the suspended flocs inside the cylinder must be equal. Since this shear force per unit area can
be equated to the pressure due to the submerged mass of solids suspended by the upflowing
liquor, the mass of solids within each cylinder must be the same.
Consider the mechanism by which stable equilibrium is achieved. Assume that the mass of
solids within one cylinder is less than that within the other cylinders. This implies that there will
be a lower pressure drop across that cylinder, and -since the cylinders connect between the
same reservoirs, this lower pressure drop will result in a higher flow rate into that clarifying
cylinder. This increased flow will transfer more solids into that cylinder re-establishing
equilibrium.

3.3 THICKENING AND SLUDGE DEWATER/NG
In the context of gravity solid/liquid separation, thickening can be considered as the process
by which the density of a suspension is increased by expulsion of the liquid, which is closely
associated with the solids in the slurry, i.e. the water within the interstices between the flocs,
and within the floc structure itself. By contrast, dewatering is the process by which free water
is removed from the suspension.
In a deep bed gravity clarifier/thickener, such as the E-CAT'm Clarifier Thickener, operating
under steady conditions, three distinct horizontal zones are formed.
The upper zone, into which the destabilized suspension is fed, is termed the "Free Settling
Zone", since in this zone the particles and flocs are each free to settle without interference by
adjacent particles and flocs.
Below the Free Settling Zone is the "Hindered Settling Zone" in which the solids volume
fraction is higher, and in which the particles settle at slower rates, hindered by displaced water
rising between the bed of flocs and particles.
At the bottom is the "Compaction or Consolidation Zone". In this zone most of the water in the
original suspension has been displaced so that the flocs and particles are in contact.
Intergranular pressure, due to the submerged mass of the solids above the level, increases.
In the Compaction Zone, the pathways through which displaced liquid can escape to the
Hindered Settling Zone above, are small and convoluted. In the case of a fine grained solid,
the resistance to flow of the displaced liquid can be high. This results in the build up of excess
pressure within the liquid known as pore water pressure. Since the intergranular pressure and
the pore water pressure together support the mass of the particles above the level under
consideration, an increase in pore water pressure means a corresponding decrease in
intergranular pressure. Since it is the intergranular pressure which squeezes the water out
from between the flocs, and from within the floc structure itself, any effective thickening device
must provide means for preventing the build up of pore water pressure.
12

Given the above definition, dewatering of the suspension must take place before thickening
can commence. Dewatering will take place in the Free,Settling, and Hindered Settling Zones.
Thickening occurs only with the Compaction Zone.
Sludge dewatering involves providing pathways through which water, entrained within the
suspension, can be easily released. Once this has been accomplished, the pore pressure
reduces and intergranular pressure increases forcing the solids into a tighter packing, driving
out even more free water to give an even higher underflow density.
Taking this theory and putting it into practical terms, the opportunity for dewatering, in the
E-CATTM Clarifier Thickener, is provided by a set of sloping surfaces called dewatering cones.
As the solids move downwards through the clarifier/thickener, pathways are provided on the
undersides, or lee sides of the sloping surfaces, through which water, forced by the higher
density of the solids, can escape.
When the E-CATTM Clarifier Thickener is in operation, heavy solids in the feed, and large,
dense, flocs formed inside the clarifying cylinders drop down into the cone of the tank. As this
fairly thin slurry fills up the spaces between the dewatering cones, it enters a region of relative
calm, protected from directly descending solids. Under these conditions, the solids in the
suspension settle out and slide down the top surfaces of the cone below, leaving almost clear
water in the spaces between the cones. The water inside the dewatering pipe, at start up,
contains no solids, since any solids in the dewatering pipe would have settled out.
At this stage the system is hydrostatically out of balance. Consider the slurry below the lower
cone. Typically the feed slurry might have a relative density of, say 1.2 and the lower part of
the clarifier/thickener is filled with slurry of increasing density. However, in contrast, the
dewatering discharge pipe, from the cone is filled with liquid with a density of 1.0, that may
contain a few suspended solids. The resulting pressure imbalance causes a flow upwards in
the dewatering discharge pipes. This leads to an accelerated dewatering and thickening of the
slurry as the released liquid flows "up" from the cones into the feed/mixing well. This process
is continuous and is powered by the heavy solids in the feed at the top of the E-CATTM Clarifier
Thickener, which continually displace liquid as they drop to the bottom of the unit.
13

The cone dewatering system is self regulating. As liquid is drawn out of the slurry, between
the dewatering cones, a point is reached when most of the free liquid has been removed and
light solids are taken up with the liquid. The solids content of the liquid in the dewatering
discharge pipes increases, the out of balance hydrostatic pressure decreases, the flow slows
down and hydrodynamic equilibrium is reached. At this stage, which is reached within
minutes, the dewatering pipes are discharging liquid containing perhaps 1000 ppm s/s into the
feed/mixing well. This dilutes the feed slurry in the well, rapidly stabilizing the flow pattern.
This internal recycle has effects other than accelerating the dewatering and thickening of the
slurry. The first is the dilution of incoming feed. The second effect is where the fine solids in
the upflowing water are mixed with incoming slurry in the feed/mixing well. This can result in
savings in flocculant.
Thick slurries are generally difficult to flocculate. The dilution of the feed slurry results in
improved flocculation efficiency, and substantial savings in the costs of flocculants, as
illustrated .in Figure 5. This effect is well. documented and is related to better distribution of
flocculants in a more dilute suspension.
The E-CATrm Clarifier Thickener has been used for the clarification and thickening of liquids
containing only a few parts per million of suspended solids. In this application the difference in
density between the slurry in the Free Settling Zone, and the liquid in the dewatering discharge
pipes is very small. This part of the system provides very little "pumping" or accelerated
thickening effect. However, when the suspended solids gradually build up in the lower cone of
the clarifier/thickener, and the slurry dewaters between the cones, a difference in density is
gradually built up between the slurry around the dewatering cones and the central dewatering
discharge pipes, which have been filled with liquid. The effect is to drive this liquid up the
discharge pipes and into the feed/mixing well, while more slurry enters, between the cones, to
take the place of the ejected liquid and the thickened slurry, which due to its increased density,
has dropped further down into the bottom cone of the E-CATTm Clarifier Thickener.
As before, liquid exiting from the dewatering cones will pick up solids, increasing the density of
the liquid traveling up the dewatering pipes, until dynamic equilibrium is reached between the
energy, due to the difference in densities and friction losses, mainly in the dewatering
14

pipes. The solids content of the liquids exiting from the dewatering discharge pipe could be
higher then the solids content of the feed suspension. Thus instead of diluting the incoming
feed, the 'internal recycle actually increases the suspended solids level.
This can have three benefits: First, flocculated solids are reused, often decreasing the amount
of flocculant used. Second, ortho-kinetic flocculation is enhanced with a higher floc volume
concentration. Third, the recycled flocs can aid in precipitation or nucleation.
It is apparent that the cones in the Free Settling Zone,, the Hindered Settling Zone and the
Compaction Zone have different purposes.
In the Free Settling Zone there is very little difference between the density of the liquid around
the cones, i.e. the density of the diluted feed, and the density of the slightly dirty liquid in the
dewatering pipe and between the cones. Therefore, there will be very little movement of the
liquid from the Free Settling Zone, through the cones, up the dewatering pipe and back into the
feed well.
The cones in the Free Settling Zone have two main purposes:
a) To provide an escape route for any air bubbles dragged down inside the
E - CatTm clarifier thickener tank by the down feed velocity of the suspension in the
feed well.
b) To continue to provide feed dilution, should the level of the Hindered Settling Zone
rise due to underflocculation, temporary problems with the underflow pump, or a
change in the settling properties of the solids in the feed solution.
15

_ The cones in the Hindered Settling Zone transfer large flow rates of liquid from the Hindered.
Settling Zone back to the feed well. The main purposes are therefore:
a) To provide feed dilution water.
b) To "collapse" the Hindered Settling Zone. By withdrawing water from the Hindered
Settling Zone the thickness of this zone is reduced, i.e. the time taken for the slurry to
dewater from the concentration of the Free Settling Zone, to the concentration of the
Compaction Zone is decreased. This means that more volume is available for the
Compaction Zone which implies a longer solids retention time in the Compaction Zone.
The increased depth of the Compaction Zone leads to a higher total pressure at the
sludge outlet. These factors can lead either to a higher underflow density, or a higher
throughput.
The cones in the Compaction Zone serve mainly to extract the small flowrate of liquid
necessary in thickening the slurry to the specified underflow density.

INTRODUCTION
There is a mild technicalogical revolution underway in the thickening and clarification
arena. It began about five years ago with the introduction of an innovative rakeless
clarifier thickener invented by Richard Batson, which produces a high quality dense
underflow while also producing a good quality overflow. This type of unit has taken hold
in the South African Minerals market with grand vigor to the point that nearly 85% of all
thickener/clarifiers sold within the last three years are the rakeless type. The influence is
logically spreading to other mineral markets around the world. A good Canadian
example are the two twelve meter units in operation at BHP's Ekati Diamond Mine
located in the NWT. These were noted in the January and the February 1999 issues of
Mining Engineering that highlighted this mining operation. It is the objective of this
paper to acquaint the reader with an overview of how the units work, the principles
involved, plus a look at actual operational data from several different minerals
applications.
THICKENING AND CLARIFYING OVERVIEW
Thickening has been an integral part of mineral processing since the introduction of wet
processing centuries ago. The conventional thickener has been the workhorse of the
dewatering process for concentration, CCD, and tailings steps. These ubiquitous
thickeners underwent few changes until the advent of polymers. Since their introduction
the gravity settling was enhanced allowing more solids to be settled in a shorter time or
with smaller unit areas. Gradually over the past three decades new types of thickeners
have been introduced. The high capacity types using improved feed dilution systems
maximizing the efficiency of the flocculants have become the mineral industry
workhorses. These high capacity units were able to reduce the unit areas required for
settling the solids to one tenth of the original conventional thickeners.
Current practice, if overflow clarity is required, is to put in a clarifier to obtain the good
overflow with a low solids content followed by a thickener to thicken the underflow.
Should the underflow be the target then a thickener's overflow is often treated by a
clarifier.
About five years ago a new thickener concept was patented in South Africa. It combined
the principles of sedimentation and clarification into a single unit. The unique aspect of
this new combination unit is that it does not require the use of rakes.
ARE THE RAKELESS CLARIFIER THICKENERS NEW & INNOVATIVE?
Baker Process recognized the potential of the Batson "Wrencat" rakeless clarifier
thickener and acquired the patents that covered it. With a few modifications the rakeless

clarifier thickener is now known as the Baker Process "B - CAT TM Clarifier Thickener".
The CAT part of the name stands for Clarifier And Thickener, which is indeed
appropriate nomenclature as both the clarification and thickening technologies are
encompassed within the unit. Initially there was considerable skepticism as to the reality
of the claims of a rakeless unit producing a denser underflow than most thickeners while
maintaining a good quality low solids overflow. The fact that this was true plus the unit
had the capacity to do the work of larger or multiple thickeners was confirmed by Baker
Process through visits to the Harmony Gold Plant and other sites in South Africa. At that
site, one ten meter diameter rakeless clarifier thickener had replaced ten old 25m diameter
thickeners. This unit was being controlled by a single operator, from a remote control
room. This was only one of his many duties. The plant indicated that they were pleased
with the unit and had made substantial savings in the areas of flocculant consumption and
maintainence costs. At this point decisions were made and the technology transferred to
Baker Process. The overall benefits and features of the rakeless clarifier thickener units
are illustrated in Table I — "Features and Benefits of rakeless clarifier thickeners."
The idea of operating a thickener on a continuous basis without a raking system makes
the hair on ones neck stand up, but it is not such a frightening thing as one might think.
These units are easy to start up and shutdown and may actually be allowed to stand idle
for a period of time with little risk of pluggage. Good judgement, as always, should be
exercised and the general rule of thumb is to clean out the solids in the compaction zone
(the bottom conical section) before any lengthly shutdown.

WHAT DOES THE RAKELESS CLARIFIER THICKENER LOOK LIKE?
VES
FIGURE I — THE RAKELESS E CAT
CLARIFIER THICKENER
Figure 1— The E - CATTM Rakeless Clarifier Thickener
The rakeless clarifier thickener has a number of unique characteristics that allow it to
perform with efficiency the clarification and thickening in a single unit without the use of
rakes. To better understand how this is accomplished each key component of the unit

will be explored and explained. In generalities the E — CAT clarifier thickener has a
smaller footprint requirement than does an equivalent high -rate thickener, however is
much taller.
Figure 1 — "The E - CATTM Rakeless Clarifier Thickener" illustrates how the feed is
introduced into the feedwell which is fairly standard. The feed is diluted by the rising
liquor from the dewatering cones. Flocculant is added to enhance the settling of the
solids. As the diluted feed journeys downward it must pass by the dewatering cones
which quickly extract the liquor and direct the solids toward the compaction zone. This
rapid dewatering occurs in what is commonly known as "The free settling zone" and
continues through the diminished "Hindered settling zone". The majority of the solids
will have reached the "Compaction zone" which is the area where the soilds further
agglomerate and densify due to the head pressure on them. At the apex of the unit's
bottom cone the solids are discharged through a nozzle into a pumping system.
The liquor that is not recycled through the dewatering cones must pass through the
clarifying cylinders prior to discharge. The clarifying cylinders are actually polishing
clarifiers that remove a very high percentage of the remaining solids. Thanks to these the
liquor effluent is remarkably clean at discharge.
Having taken an overview of the rakeless clarifier thickener it will be helpful to examine
each area and component in detail to better understand it's contribution. This will be
done as much as possible along the natural feed flow path.
HOW DOES THE RAKELESS CLARIFIER THICKENER WORD?
FEED SYSTEM AND FEEDWELL
The feed solids concentration will vary depending upon the source. The E — CAT
clarifier thickener can handle a wide range of feed concentrations from the fairly dilute to
the heavy. Most feeds do not require dilution beyond that provided by the upflow from
the dewatering cones. Feeds that are high in solids will frequently require additional
dilution to bring the concentration to the ideal for good flocculation as shown in figure 2.-
" E - DUC® Feed System Option". This is accomplished by use of an E — DUC ® feed
system that uses the supernatant which is drawn into a mixing tube by the force of the
incoming feed stream. The importance of providing a proper solids concentration is
shown in Figure 3 — "Effects of Feed Concentration". Flocculant consumption is at
optimal efficiency at the correct solids concentration. Once the proper concentration is
accomplished the feed is injected with a flocculant. This begins the solids agglomeration,
which aids in the more rapid settling of the solids, in accordance with Stokes Law. This

is a key step in any successful operation that will impact the rate of solids settling as well
as the consumption of flocculant. From this point on the principles of physics will
govern. The formation of the flocs is generally very rapid. In cases where dual
flocculants are required one may be added upstream of the feedwell at a sufficient
distance to allow completion of the reaction. The purpose of the feedwell is to provide a
contact zone for feed and flocculant, control dilution, dearate the feed, and to channel the
flocculated feed solids toward the dewatering cones.

DEWATERING CONES
The dewatering cones are the heart of the dewatering process. The cones provide extra
surface for the solids to contact and release the liquor. The solids traverse down the
outside of the cones settling toward the compaction zone. The liquor takes the shortest
path of least resistance and goes on the underside of the cones.. The liquor rises upward
passing through windows into a central pipe that transports the liquor upward to the
feedwell where it is discharchged. Figure 4 "Upflow from dewatering cones" clearly
shows this rising liquor. What makes this work? The more dense incoming solids act
like an pump driving the lower density liquor upward and into the feedwell. This action
has been equated with an artesian well. These dewatering cones are suspended from the
bridge allowing them free movement in response to the mighty forces. encountered within
the tank.
The dewatering cones are key in the rapid liquor removal which collapse the hindered
settling zone. This is the limiting settling factor in conventional thickeners. The
minimization of the hindered settling zone allows the rapid liquor removal to occur in the
free settling zone where the resistance is the lowest for the particles and liquor. This rapid
and volumeous removal of the liquor is the main reason for the smaller diameter of the
rakeless clarifier thickeners." This is why when performing lab settling testing the free
settling part of the curve is so important. Unlike sizing for thickeners, which use the
Wilheim Naide or the Finch Tamel methods that use the tangent point on the curve where

it breaks, the E — CAT clarifier thickeners are sized on the free settling portion of the
curve. Figure 5 — "Settling Tests" show visually and graphically these principles.
The dewatering cones descend down from the feedwell to the top of the compression
zone. The size relationship to the tank is nicely illustrated in Figure 6 — "Dewatering
cones for a 10 in E — CAT clarifier thickener."
Figure 4 — Upflow from dewatering cones Figure 5 — Settling Tests

Figure 6 — Dewatering cones for a 10 m E - CAT TM clarifier thickener
COMPACTION ZONE
The solids arrive at the compaction zone well dewatered. As they descend through the
compaction zone the solids begin to consolodate as a result of the compressing weight
from the solids and liquor in the tall tank. The solids will achieve a higher density
generally than is possible in a conventional or high rate thickener. The consistency at the
discharge nozzle is uniform and can approach the area of paste in some instances. Figure
7 — "Underflow from a mineral sands application" show what the underflow discharge
looks like. The underflow is discharged through a nozzle into a pumping system. The
type of pumping will depend on the process and the characteristics of the solids. Variable
speed pumps are suggested followed by density and flow meters. This will provide a
good basis for control and will work well with PLC controls. The top of the compression
zone is detected by a level sensor. The sensor transmits a signal to the control central
and may be used to determine the flocculant feed rate and assist in determining the
underflow rate.

Figure 7 — Underflow from a mineral sands application
CLARIFICATION CYLINDERS
The liquor that does not rise up the dewatering cones or go out with the underflow must
pass through the clarifying cylinders. These cylinders are designed to promote
orthokinetic flocculation of the solids entrained in the rising liquor. The solids collide
and serve as nucleation points for other solids until they reach sufficient density and mass
to settle. These cylinders are in reality minature little clarifiers that polish out the
entrained particles. The zone of clear liquor above the cylinder banks is the last area
where the solids will come out due to the reduced velocity. The resultant liquor is very
clean and is frequently of such quality that it is reintroduced back into the process without
causing a fines buildup. The clean overflow liquor is produced with out sacrificing
underflow density. The underflow density, as noted in the previous section, is of
excellent quality. Figure 8 — "Clarifying cylinders" is a cut away showing the
relationship of the clarifying cylinders to the feedwell and the dewatering cones.

APPLICATIONS THAT HAVE USED THE RAKELESS CLARIFIER
THICKENERS
The rakeless clarifier thickeners have gained prominence in the mineral fields of South
Africa and are gaining acceptance in other parts of the world as well. The use of pilot
plants have helped to determine the feasibility of using the units for different
applications. Figure 9 —" E - CATTM clarifier thickener CCD pilot plants" shows several
pilot plants in a CCD train. Considerable data has been gained from these tests and from
actual working full scale units. Table II — "E - CATTM clarifier thickener applications
guide" provides eight examples of units in operation.
The rakeless clarifier thickener is not a "cure all", but does have a real place in mineral
applications. They are not recommended for feeds with low density solids, however they
work exceptionally well in coal washing applications. For questionable applications
bench scale lab tests will give a good indication of whether it is a good canidate or not.
The type of underflow solids expected from the units may be determined by allowing a

1000 ml cylinder filled with flocculated feed sample to settle overnight and measure the
resultant solids. What is achieved in the cylinder can easily be produced by an full scale
operating unit. Pilot testing is a good investment that may confirm the reality of the
claims of the new state of the art thickener/clarifier.

CONCLUSIONS AND RECOMMENDATIONS
The rakeless clarifier thickeners are the new state of the art thickeners that have made an
impact on the minerals industry. These units represent a significant technological
'thickening and clarification can be accomplished in a single unit without rakes is
noteworthy. At this point in time there are somewhere around 95 units in operation or
under construction around the world. The rakeless clarifier thickener should be
considered for minerals applications, and, if unsure, run pilot tests. The rakeless clarifier
thickeners are here to stay and provide advantages over other types of thickeners in many
instances.

ABSTRACT I Me
This paper summarizes the Wren CAT (Clarifier and Accelerated Thickener) deep bed thickener
operation at the EKATFTM Diamond Mine in Canada's Northwest Territories. EKATFM's
thickener project is presented in terms of initial design considerations and present day operating
practices. A circuit description summarizes process equipment, reagent systems, and typical
process conditions, and details of Wren CAT operating principles are provided. Operating
strategies are discussed, with emphasis on process instrumentation and control and operating
challenges.
INTRODUCTION
The EKATF m diamond mine, operated by BHP Diamonds, Inc., is located in the Northwest
TerT;tnriec near Lac De Gras, �.Ir vx: :: .:iy 300 km NNE of Yellowknife, NT. 9000 dry metric
tonnes of diamond -bearing kimberlite ore are processed daily. Processing operations commenced
in October, 1998.
The EKATITM process plant flowsheet features typical steps in diamond recovery plant design.
Figure 1 shows the general plant flowsheet. Size reduction and feed preparation are
accomplished by crushing, scrubbing, and high pressure grinding rolls (HPGR) through closed-
circuit classification with vibratory screens. Heavy medium separation (HMS) is used as the
initial stage of heavy mineral concentration. Secondary concentration is accomplished in the
recovery plant by attrition milling; wet, high -intensity magnetic separation (both wet and dry);
and X-ray sorting.
The present budget throughput rate is 9000 dry tonnes per day. This will be increased to 18,000
tonnes during the first ten years of operation. Unlike most kimberlite treatment facilities, which
process material from a single ore body, EKATrr""a pruccss plant was designed to accommodate
ore from five different kimberlite pipes, each with its own treatment characteristics.
All processing, except for primary crushing, is carried out in a temperature -controlled
environment in the main process plant building.
Two tailings streams discharge from the EKATITM process plant. Coarse tailings are comprised
of HMS circuit tailings in the size range minus 8 mm to plus 1.2 mm. Added to this are the plus
0.65 mm to minus 1.2 mm fines fraction from the feed preparation area. These coarse tailings are
transported by a conventional belt conveyor to an external stockpile and removed with a front-end
loader and truck. Fine tailings are comprised of the minus 0.65 mm fines fraction from the
vibratory screen underflows from the feed preparation circuit. This is thickened, with the
assistance of polymer addition, in deep -bed compression thickeners, supplied by Wren
Technologies (Pty.) Ltd. The advantage of this unit lies in its small footprint, high capacity per
unit area, and the fact that there is no rafting mechanism and therefore no moving parts.

INITIAL DESIGN CONSIDERATIONS
The EKATIrm thickeners are designed to operate continuously, 24 hours per day, 365 days per
year, with minimum downtime for maintenance. Thickener operation objectives are to maximize
underflow densities consistent with manageable tailings pumping rheological behaviour, with
minimal consumption of reagents, and ultimately to minimize plant makeup water demand and
therefore overall operating costs. Two 12 m diameter x 17.5 m high thickeners are used to
partially dewater the tailings slurry prior to pumping to the tailings impoundment area.
The Wren CAT (clarifier and accelerated thickener) deep -bed device was chosen for EKATITM's
application over both a high -rate and a conventional thickener. Below is a list of the advantages
and disadvantages of the Wren CAT that were most important for this application, as compared
with those of other thickening and dewatering devices.
POTENTIAL ADVANTAGES OF THE WREN CAT
- high thickener underflow densities are achievable with the Wren CAT (This is an
important advantage, due to the considerable distance of 8.2 km to the tanings line

utilized as process water)
the Wren CAT performs well over wide ranges of flowrates, pulp densities, and
particle sizes. (This•is vital to EKATITM, since the feed characteristics over the mine
life are expected to vary drastically, in addition to significant day to day variations.
Since the characteristics of the individual contributions to thickener feed differ
substantially, thickener feed characteristics will thus change drastically depending on
the relative proportions of each source at any given time. )

POTENTIAL DISADVANTAGES OF THE WREN CAT
- considerable pumping capacity is required to overcome the large static head, because
of the large height to diameter ratio.
- limited solids surge capacity; therefore, any problem at the thickeners or downstream
requires a rapid shutdown of solids feed to the thickener
A Wren pilot scale CAT was used at BHP's Koala bulk sampling plant, prior to the design and
construction of the main EKATITM process plant. Extensive testing of this pilot unit proved its
suitability for the application. In this particular instance, the deep bed compression type thickener
was the only feasible option due to limited space.
THICKENING AND TAILINGS CIRCUIT DESCRIPTION
EQUIPMENT
Feeding Arrangement
Several sources contribute to thickener feed: feed preparation circuit fines; HMS circuit effluent;
recovery plant effluent; and three sump pump discharges. Figure'2 illustrates the thickener
flowsheet. Thickener feed represents an average of approximately 75% of plant head feed.
The primary roles of t'ne feed preparation area are to generate fines and therefore reduce the
amount of material requiring further downstream processing and to Jibe►ate diamunds wiihoui
stone damage. The primary scrubbing/degritting circuit handles the main plant feed. Oversize
from the primary circuit is conveyed to HPGR for recrushing. HPGR discharge then proceeds
through the secondary scrubbing/degritting circuit.
Each of the primary and secondary degritting circuits involves classification via a double -deck
banana screen, the degrit screen (top deck apertures are 1.2 mm and those of the bottom deck are
0.65 mm). Degrit screen underflow (minus 0.65 mm) is pumped via a 14x12 pump to a collection -
launder approximately 22 m above the pumpbox level. Also to this launder are added HMS
circuit and recovery plant effluents (both minus 1.0 mm) and coagulant and thickener area sump.
pump discharges.
Tailings in the launder flow into a distributor above the thickeners. Here the material is mixed-.. - = -- -
and can be split equally between the two thickeners. The option then exists to utilize either or .
both thickeners via a dart valving system. Design thickener capacities allow the full volume -of --
thickener feed to be handled by a single thickener with certain feed types. (Certain feed types
allow upflow velocities of 50 m/h, compared to design values of 25 m/h.)

Thickeners
Each thickener is required to effectively remove water from the solids, discharge clean water as
overflow to a launder, and produce and deliver to the underflow pipe thickened slurry of the
required density for disposal. Two 12 m diameter x 17.5 m high Wren CAT deep bed thickeners
are used for this purpose. Cylindrical section height is 6.5 m, conical section height is 11.5 m,
and the cone angle is 60 degrees. Under the control of thickener instrumentation (described in a
later section), variable speed pumps remove the slurry at a controlled rate to achieve thickener
steady state. EKATITM's Wren CATs are depicted in Figure 3.
Figure 3: Photograph of EKATITM CATs
Each thickener treats the minus 0.65 mm rejects from the feed preparation circuit. Thickener feed
is collected from two sources and is split equally between the two units under normal operating
conditions. Each source comprises a pump box with a fixed speed pump; a constant pumpbox
level is maintained by the addition of level control water. Thus, the thickeners receive a feed of
fixed volumetric flowrate and with a solids content varying according to upstream conditions.

Coagulant (cationic polymer) is added to the thickener feed in the form of a dry, 'water-soluble
powder, delivered from a hopper via a variable speed screw feeder. Flocculant (anionic
polymer), in the form of a dilute solution in water at a controlled strength, is used as a settling aid.
Variable speed pumps add flocculant solution to the thickener feed streams in the feed launders.
Thickened tailings are pumped to the tailings holding tank via 6x4 variable speed Warman
centrifugal pumps at an. average of 1.40 specific gravity, or 45% solids (weight basis). Two
underflow pumps from each thickener can be operated either individually 'or in parallel,
depending on underflow withdrawal requirements.
Thickener overflow flows by gravity to the process water tank, from where it is utilized
throughout the process plant.

Figure 4: Tailings Circuit Flowsheet
An agitated tailings holding -tank with 600 m3, or approximately 1.5 hours, surge capacity
receives thickened tailings as well as various other minor streams. Holding rank contents are
pumped by one of two tailings line arrangements. Each line consists of three stages of pumping in
series. The first stage is fixed speed, followed by two variable speed pumps used to vary flow
according to desired conditions. All tailings pumps are IM, with the first stage powered with a

250 hp motor and stages two and three with 200 hp motors. Cross over facilities are provided to
allow either set of pumps to use either line for maintenance flexibility.
Tailings of specific gravity 2.7 (dry basis) is pumped to the tailings impoundment area at an
- ----------------------- ----- --
average of approximately 670 m3/h and a slurry specific gravity of 1.35, or 40% solids (weight
basis). (Dilution water is added in the suction line, resulting in a more dilute slurry than thickener
underflow alone provides.) Total pipeline length is approximately 8.2 km, with an overall
elevation drop of 10 m. Pipe material consists of 12" diameter polyethylene -lined steel (at the
plant), changing to HPDE further downstream. Outside the plant the pipeline is insulated with 3"
polyurethane and heat traced for severe winter conditions. Three strands of heat trace are
positioned at 4, 6, and 8 o'clock along the length of the line. Electronic controllers measure and
govern heat trace activation. Heat trace power consumption is dictated by outside temperature and
fluid temperature in the pipe, with a typical range of 7.3 to 12.7 W/m per strand. The second
tailings line, also heat traced, is used for emergency and maintenance flexibility purposes.
REAGENTS
Selection
The rezoert selectio;, process commenced with laboratory scale settling tests using a 500 ml
settling cylinder and a mixing plunger. From these tests, Ciba® PERCOL® 368 coagulant was
chosen to overwhelm the charge on the fines (predominantly clays), giving the coagulated
mat,?-;-' a nPf nn�:� c}_roo r,_a-i_.:. ..a_ _, U_ Vv [r
V w W GLGI.
Coagulated material was screened with various bridging type flocculants, and, of those tested,
PERCOL 156 was determined to be the best performing flocculant in terms of settling rate,
sludge density, and water clarity for the feed types anticipated during the first few years of
operation. On different kimberlite material, to be processed later in the mine life, PERCOL E-10,
a different type of flocculant, was determined to perform well.
Subsequent testing on production -run solids showed that a newer flocculant, PERCOL 336, could
potentially 'provide better performance characteristics at a lower cost. This flocculant is currently
under an extended trial to quantify the results. Percols 156 and 336 have similar charge
characteristics, but 336 has a much higher molecular weight. 336 is expected to provide better
settling under certain conditions but 156 should provide greater flexibility over a wider range of
feed types.
Coagulation versus Flocculation
A great deal of confusion and misuse�of the terms "coagulation" and "flocculation" exist. The two
terms refer, however, to quite different processes.
Coagulation is an electrostatic process, in that the predominant mechanism is a -reduction of the
repulsive potential of the electrical double layer, thus enabling coagulation to occur. In basic
terms, this is the neutralization of the electrical potential surrounding the particles in the slurry so
repulsion does not occur among the particles, and attractive forces will then allow the particles to
form small agglomerates.

-1 Flocculation is derived from the Latin "flocculs", meaning a loose, fibrous structure.
Flocculation is brought about by the action of high molecular weight polymers such as
polyacrylamides. The polymer physically forms a bridge between two or more particles, uniting
the solid particles into -a random, three-dimensional structure, which is loose and porou-S.
Flocculation occurs when destabilized particles form into larger particles and is enhanced by the
addition of high molecular weight, water-soluble polymers.
The two processes work together to remove solids from a suspension. Coagulation first
neutralizes charged particles, destabilizing the suspended solids. Flocculation follows when these
neutralized particles begin to collide, forming larger particles.
Product Application
The coagulant, PERCOL 368, is fed neat into the slurry line, upstream of the flocculant. and
thickeners. Neat feed has proven to be more effective in terms of cost -performance, where
applicable. _
The flocculant, PERCOL 156, 336 or E-10, is first diluted to approximately 0.15 to 0.20% in an
automated Ciba make -down system. This material is fed via progressive cavity pumps to the
thickeners. Prior to injection into the feed well, additional dilution water is added to bring the
injected solution strength to approximately 0.03%. The solution is added into the slurry
downstream of the cationic coagulant addition at three points, which improves the effluent water
clarity and cost -performance versus a single addiiiun point.
Flocculant Feeding System
The flocculant makeup, storage and dosing unit is designed to receive and store dry flocculant;
prepare a flocculant/water solution batch at an appropriate strength for polymer activation to
occur; agitate and store the solution batch; transfer a complete batch of solution to the storage
tank on demand; store the solution as the supply for the dosing pumps; and deliver the required
volumetric flowrate of solution to the thickeners via variable speed pumps - one dedicated to each
of the two thickeners, with a common standby.
Further dilution of the solution in the pipe delivering to each thickener is performed by the
injection of water to a solution strength of approximately 0.03%.
The flocculant mixing and feeding system includes a 2.0 m x 2.0 m x 2.5 m stainless steel bin
with 10 m3 capacity. The design of the bin is such that it will accept 1 m3 bulk bags at the top of
the bin and prevent the spread of flocculant powder into the environment. -
Flocculant is delivered to a hopper via a screw feeder. A 5 hp blower pneumatically conveys the
flocculant from the storage bin to the mixing unit through a 2" pipeline approximately 15 M in
length and at an elevation of 12 m above floor level. A mixing tank, 4.0 m diameter x 4.5 m hiQh.
with a working volume of 45 m3, receives the conveyed flocculant. In the mixing tank, a
dispersion and wetting system mixes the dry flocculant powder with water to produce a
nomogeneous solution. The mixing tank has a 10 hp motor agitator and utilizes a jetwet mixing

system. It is located above the flocculant storage tank to allow gravity discharge from the tank to
a 5 m x 5 m storage tank of 90 m3 capacity. Storage tank working volume is approximately two
times greater than that of the mixing tank to provide appropriate overlap and surge capacity_
Three progressing cavity type dosing pumps — two operating and one common spare — meter the
flocculant solution to its dedicated thickener through a 4" diameter pipeline approximately 50 m
in length to an elevation of about 20 m above the pump suction. Dosing pump flowrate is
controlled by a 4-20 mA signal to a variable frequency drive, with flowrate being linearly related
to the signal current. Pumps are of such an internal design and maximum speed of rotation to
impose minimum degradation of the flocculant at maximum demand.
The flocculant makeup, storage, and dosing units are designed for unattended operation such that,
once initiated through the plant's control system, all subsequent operations are automatic.
Operator activity is restricted to filling of the bulk storage bins.

Coagulant Feeding System
The coagulant storage and dosing unit is designed to receive and store dry coagulant supplied -in
bulk and to deliver the required mass flowrate of coagulant to the thickeners via a variable speed
controlled screw feeder.
The coagulant bin will accept 1 m3 bulk bags at the top of the bin and prevent the spread of
flocculant powder into the environment.
The coagulant feeding system consists of a 2.0 m x 2.0 m x 2.5 m storage bin of 10 m3 capacity, a
bin withdrawal system (screw feeder and blower system), a day bin, and a dosing screw feeder.
A 5 hp air blower pneumatically conveys the coagulant from the storage bin to the day bin
through a 2" diameter pipeline approximately 20 m in length and at an elevation of approximately
28 m above floor level. The day bin receives coagulant from the main storage bin. Bin filling is
controlled automatically by high and low level signals. Dosing screw feeder speed is controlled
by a 4-20 mA signal from the plant's control system, with the feeder speed being linearly related
to the signal current. "
The coagulant storage and dosing units are designed for unattended operation such that, once
initiate through the plant's control system, all subsequent operations are automatic. Operator
activity is restricted to filling of the bulk storage bins.

FLOCCULATION AND FEED
A CAT separates solids from liquids at high feed rates. Proper feed dilution to an optimum
concentration for the most efficient polymer use is desired, as proper dilution and flocculation is
vital to the success of the CAT.

rising from the dewatering cones. Flocculant is added into the feed/mixing well. Hydraulic
mixing, due to the energy of the feed stream entering the feed well, is sufficient for flocculant
dispersion. Large stones and heavy objects pass directly into the bottom cc,-.-- of the CAT to be
discharged.

CLARIFICATION IN THE CAT
Clarification is accomplished via "clarifying cylinders". Figure 8 shows these cylinders in a top
view of a thickener. The clarifying cylinders, of circular cross section, are arranged in rings
around the feed/mixing well. The cross section of each cylinder increases slightly with height,
and each is open at both top and bottom. Figure 9 shows the undersides of the cylinders.
As illustrated in Figure 7, once the feed suspension has entered through the inlet pipe it passes
downward into the body of the thickener. Thickened solids are withdrawn through the sludge
outlet in the bottom of the cone. The remainder of the suspension passes upwardly, through the
clarifying cylinders, towards the overflow.
Figure 8: Overlooking Clarifying Cylinders
Initially, upon entering the bottom of the cylinders, the solids in suspension are in the form of
discrete particles or small flocs. Since, due to their small mass, these particles have low -settling
velocities, they will be carried up by the flow of the suspension .entering the cylinders. .,The liquid
motion causes collisions among the flocs, thereby forming larger, and under the right conditions
more dense, flocs. Since the cross sectional area of .the cylinders gradually increases as the flow
moves upward, the velocity of the liquid gradually decreases. Those particles or flocs that are
close to the terminal settling velocity at any given height in the cylinders remain'suspended until
additional collisions with other particles or flocs .cause the formation -of larger flocs. Eventually,
each floc becomes sufficiently large anryor dense to drop gown against .the flow, ultimately to
�' ,I exit from the lower, open ends of the cylinders.

ditions in all cylinders are virtually identical, since the system is in equilibrium. For
'Pose the mass of solids within one cylinder becomes temporarily less than that
:her cylinders, with a corresponding pressure drop across the cylinder. Since all
from and discharge to common reservoirs (that is, the volumes of liquid below and
inders, resrz;.;i,,,ely), the lower pressure in the cylinder in question will result in a
to into that cylinder, bringing in more solids until the equilibrium is re-established.
J AND DEVA'ATERING
:he process by which the density of a suspension is increased by removal of the
iaied with the solids in the slurry, or the interstitial •,;•ater among the particles
. str'Jcture. Dewatering, on the other ha-.2, is the Yr�by which free water is
t*pension.

,z In a deep bed CAT operating at steady state, three distinct zones exist: free settling, hindered
settling, and compaction. Dewatering t ;cs race in t ;e fiee, settling and hindered settling zones.
Thickening occurs only within the compaction zone.
The upper zone, into which the feed suspension is injected, is termed the "free settling" zone,
since in this zone the individual particles and flocs are free to settle without interference from
each other.
Below the free settling zone is the "hindered settling" zone, in which the proportion of solids is
higher and in which the particles settle more slowly, hindered by rising displaced water.
At the bottom is the "compaction" zone. By the time solids enter this zone, most of the water in
the original suspension has been displaced so that the flocs and particles are in contact.
Intergranular pressure, due to the mass of the solids above, increases.
"At first glance, a deep thickener gives the impression of being a device which cannot work. This
is because. it is.�yl..y LL InL LiiC iiLIuiu bc17araleQ IrOm Lr1e 5oha In the
lower parts of the vessel can permeate at any worthwhile rate through the great thickness of the
compacting bed above it. The fact that deep thickening does work, and works at high dewatering
rates per unit cross -sect+- area, is attributed to the formation of channels throughout the
compacting bed." (cn" d")
Dewatering occurs by a set of sloping surfaces called dewatering cones, as illustrated in Figure 7.
As the solids move downwards through the CAT, pathways are provided on the undersides of the
slot; s;:-faccs, through which water, forced by the higher density of the solids, can escape.
When the thickener is in operation, heavy solids in the feed and large, dense flocs formed inside
the clarifying cylinders drop down into the cone of the tank. As this slurry fills up the spaces
between the dewatering cones, it enters a region of relative calm, protected from directly
descending solids. Under these conditions, the solids in the suspension settle out and slide down
the top surfaces of the cones below, leaving almost clear water in the spaces between the cones
that me . -
'cs .«r4.,....t;, u,_Watering pipe.
The feed slurry is denser than the liquid in the dewatering pipe discharge, with a resulting
pressure imbalance, and the dewatering pipe' discharge mixes with the feed. This has two
important effects. Firstly, the feed slurry is diluted; secondly, fine solids in the upflowing water
are mixed with incoming slurry. Both effects lead to improved flocculation and therefore lower
consumption of reagents and good settling.
The cones in the free settling zone have two main purposes. Firstly, they provide an escape route
for air bubbles trapped in the feed; secondly, they continue to provide feed dilution, should the
hindered settling zone rise.
The cones in the hindered settling zone are mainly used to transfer large flowrates .of liquid from. - ....-..
the hindered settling zone back to the feed well to provide feed dilution water and to collapse the
hindered settling zone. By withdrawing water from the hindered settling zone, its thickness is
reduced and the volume of compaction zone increases. -
The cones in the compaction zone primarily help to extract t_h_ a small fl_owr_a_te of liquid_necess.ary_
in thickening the slurry to the specified underflow density.

OPERATING STRATEGIES
PROCESS INSTRUMENTATION AND CONTROL
The instrumentation and control discussion below is divided into the following five areas:
thickener feed, thickening, flocculent addition, coagulant addition, and tailings handling.
Thickener Feed
Thickener feed originates from two principal sources, primary and secondary degritting, with
'nor contributions. A magnetic flowmeter positioned on each of the primary and
secondary degritting streams determines the volumetric flowrate to the thickeners at any give
time, and a nuclear density gauge positioned on each line provides the specific gravity of the
slurry. Based on an assumed dry solids specific gravity of 2.7, the mass flowrate from each
stream is determined. The two streams are mixed prior to entry into the thickener feed
distribution area. Thickener feed is then directed to one or both thickeners through a dart valving
system. Both thickeners operate in parallel under normal cirr,irnstances.
Thickening
Thickener instrumentation monitors the solids loading in each thickener (on a dry tonne basis)
with a pressure load cell. The bed/water interface level is detected by ultrasonic methods and is
expressed as a percentage of thickener height. A probe that detects ti,c amount of light reflected
by suspended solids, positioned at the thickener overflow discharge, measures turbidity. A
nuclear density gauge positioned in each of the underflow lines, located downstream from the
pumps, monitors thickener underflow pump discharge density. This may or may not be indicative
of the actual thickener underflow density, as explained below. Likewise, the thickener underflow
pump discharge flowrate — not necessarily the thickener underflow withdrawal rate - is measured.
by a flowmeter positioned on each of the lines downstream from the pumps. The power draw on
each of the underflow pumps is continuously measured.
Each of the thickener underflow pumps is operated in one of three modes: manual, auto, or
cascade: In manual mode, the pump operates at a set percentage of the motor speed. In auto.
mode, the pump speed varies to maintain a constant volumetric flowrate. In cascade mode, the
pump speed increases or decreases to maintain a constant slurry density through the thickener
under -flow line. This density is limited to prevent sanding in the line. Should the specific gravity
increase to a level of 0.05 greater than the setpoint, water is automatically injected into the
suction line. In this case, the specific gravity and volumetric flowrate of the slurry would be
lower than that of the thickener underflow. Slurry specific gravity through the lines has
approached 1.50 with no difficulty. A minimum pump speed prevents slurry velocity from
decreasing below the limiting settling velocity. '

Flocculant Addition
Flocculant addition system instrumentation allows for control of feeder speed, batch strength,
mixing time, and flocculant mixture flowrate. The power draw on each of the dosing pumps and
the level in each of the mixing and storage tanks are also monitored. One flocculant pump
dedicated to each thickener, with one common pump on standby, allows independent flocculant
addition control to each thickener. Each of the flocculant dosing pumps is operated in one of
three modes: manual, auto, or cascade. In manual mode, the pump operates at a set percentage of
motor speed. I-, auto mode, the pump speed varies, depending on the mass flowrate of thickener
feed, to deliver a constant dosage (indicated in grams of flocculant per dry tonne of feed). In
cascade mode, a system supplied by Ciba, a Quick Dose Control system (QDC), controls the
pump speed. A submerged probe moriters the clarity of the slurry in tile, iccu weii of the
thickener. The QDC takes readings at set time intervals and determines, using its PLC Ric-rithm,
whether the reading is in or out of the required range. If the reading is out of the required range,
the PLC reduces or increases the flocculant dosage accordingly.
Coagulant Addition
Coagulant feeding system instrumentation monitors the day bin level and the screw feeder speed.
The coagulant system, similar to that of the flocculant, is operated in•one'ofthree•modes-: mantial,••
auto, or cascade. In manual mode, the feeder operates at a set percentage of the motor speed. In
auto mode, the feeder speed increases or decreases, depending on the mass flowrate being fed to
the thickeners, so a constant dosage (indicated in grams of coagulant per dry tonne of feed) is
delivered. in cascade mode, the QDC system controls the feeder speed. Whereas flocculant
dosage in cascade mode is controlled completely by the clarity of the slurry in the feed well,
coagulant dosage is based pa—zdly or, the amount of flocculant being delivered at any given time.
A constant set coagulant dosage is maintained until the flocculant dosage exceeds . a
predetermined level for a certain period of time, after which it increases at a set rate.
Tailings Handling
Tailings handling system instrumentation allows for control of the tailings storage tank level,
pump speeds, tailings discharge rate, and tailings discharge slurry specific gravity. Since the
second and third stage pumps in each lire auc vatial7.1c spcea, the flow through each line is
controlled in one of manual, auto, or cascade u, rnan uai ir,ode, the pumps operate at a set
percentage of motor speed. In auto mode, pump speeds increase or decrease to maintain a
constant flowrate through the tailings line. In cascade mode. numn cnPPric .,at„ tn rng;nt-n;n a
constant level in the tailings holding tank. In addition to flowrate control, maximum slurry
density is also controlled. Water is added to the suction side of the pumps in the event that the
slurry specific gravity increases above the setpoint.

OPERATING PRACTICES
Operations personnel, with the assistance of the instrumentation described in the above section,_._...•-_-
monitor various aspects of thickener operation. Thickener performance is evaluated mainly by
the following criteria: 1) thickener loading (tonnes of dry solids) and interface level (percentage
of thickener height); 2) overflow turbidity (NTL1); and 3) underflow slurry specific gravity.
Problems are encountered when one or more of the above varies to an unacceptable level.
Operations personnel intervention is then required.
To maintain the above criteria at acceptable levels, operations personnel can manipulate one or
r yore of the f01i0winig. i) ur,deiiiow density andiur puitiping raie; ii) chemical addition rates; and
iii) thickener feedrate.
Thickener Loadino
T 44cl:en ez loading will increase to an unacceptable level if one or both of the following occurs: a)
solids do not settle properly and thus remain suspended in the thickener (usually indicated by an
undetectable interface); or b) incoming feed solids flowrate exceeds that of the thickener
underflows.
in the case of suspended solids, improper reagent dosage (either an excess or a deficiency) is
almost invariably the. cause. Cationic polymer dosage rate is usually manipulated initially ----
Should the situation fail to improve, anionic dosage rate is then adjusted. The degree of
manipulation and the strategy involved are generally based on operator experience and
preference.
In the case of an inability of the thickener underflow pumps to remove. the required volume,
operators first ensure that water is not being added for density control purposes. Should this be
the case, either increasing the underflow specific gravity setpoint in cascade mode or increasing
the flowrate in manual or auto modes will increase the pumping capacity. (Increasing the setpoint
to wit hin 0.05 of the actual density will reii;ove the dilution water. Since the pump will already
be operating at full output, the net effect will be an increase in solids throughput.) Should the
slurry specific gravity approach the limit of 1.50, the pumps are then operated in double dut;
mode so that two pumps operate in parallel from each thickener. However, the downstream
portion of the circuit (i.e., the tailings pumping system) must be able to handle the additional
volume. Should the tailings handling equipment become limiting, lowering the plant feedrate
will decrease thickener feedrate. This will generally occur only if the plant feed size distribution
is very fine.
Overflow Turbidity
Thickener overflow turbidity will increase to an unacceptable level due to one of the f^". a)
a reagent deficiency or excess; or b) a solids deficiency (e.Q.. under startun cnnditions).

Should the overflow turbidity increase be due to a reagent deficiency or excess, cationic polymer
dosage rate is usually manipulated first. Should the situation fail to improve, anionic dosage rate
will then be altered. The degree of manipulation and the strategy involved are generally based on
operator experience and preference. --
In the case of an inadequate amount of solids, overflow clarity typically suffers, since hindered
settling conditions are not present. For clarification to occur in the cylinders, as described in the
"WRENCAT OPERATING PRINCIPLES" section, interparticle collisions are necessary. If too
few particles are available for these collisions, flocs do not form and particles are ejected and
report to the overflow. Temporarily decreasing the underflow pumping flowrate generally
improves this condition.
Underflow Specific Gravity
Thickener under -flow slurry specific gravity will increase to an unacceptable level due to one or
hih'Dre of Lim following: a) underflow pumping capacity is too low; b) thickener feedrate is too
high; or c) solids settling is too rapid.
In the case of inadequate pumping capacity, underflow pump speed is increased by increasing the
flowrate in manual or auto modes cr �y lo-,;;.i;,ng the underflow density setpoint in cascade mode.
The setpoint is lowered by less than 0.05 to ensure no water is added to the suction line. Should
one pump at maximum speed still prove unable to reduce the specific gravity, double duty mode
may then be initiated so that two pumps operate in parallel from each thickener. However, the
downstream portion of the circuit (i.e., the tailings pumping system) must be able to handle the
additional solids flow.
In the case of a high thirkem-r feedrpte, the plant feedrate is usually decreased until a throughput
rate that provides workable thickener conditions is reached. This generally occims only at
fine plant feed size distributions.
Should the solids settle and thicken too quickly, reagent addition rates are manipulated. There is,
therefore, a point at which flocculation and settling become too efficient for ease of thickener
rnntrnl -..--..-,egy and degree of polymer manipulation depends on feed conditions and
individual circumstances and is based mainly on operat;,i -xperience and preference.
In addition to the above operating strategies, the thickeners can be operated in either single or
double duty ri e e;th— c. e Cr1•.n.i. 1.: ,._____ ,
., •-. . both thic ene s earl bu led at any given time). Under normal
operating conditions, both ware utilized. Only when a thickener must be taken offline for
maintenance purposes is the single duty option exercised.
PRESENT CHALLENGES AND FUTURE PROJECTS
The current major challenge is reagent optimization. Optimum reagent dosages must be
Determined for various feed types. Since coagulation and flocculation are surface chemistry
based processes, the charge characteristics and the solid surface area are of greater relevance than
the mass of solids alone. Therefore, with each different feed source and its corresponding size

consist, optimum reagent dosages must be determined. This may lead to the 'discovery of
common optimum concentrations, in terms of amount of reagent per unit solid surface area rather
than the traditional approach of amount per unit mass of solids, for the various feed types. The
interactive effects of cationic and anionic species must also be considered.
In addition to the determination of optimum dosages, future work will also focus on the testing of
various reagent types on different feed materials. This will be ongoing throughout the mine life,
since among and even within individual kimberlite pipes, materials of differing surface
characteristics may respond better to other reagent types.
The utilization of the Ciba QDC system will assist in reagent optimization. Determination of the
best parameters at which to operate the QDC in combination with the plant's control system is ari
important project that has been evolving and will continue to do so. Effective utilization of the
system with various feed types has proven challenging.
Reagent storage -and handling has proven difficult since operations commenced, partly due to the
severe winter conditions experienced at the minesite. Although the reagent storage bins are water
tight, the chemicals have occasionally been exposed to moisture, resulting in screw feeding
problems. Consideration is being given to the installation of reagent storage silos. This would
involve reagent transfer from silo to bin in the absence of operations personnel.
On the present mine plan, daily processing capacity will be expanded to 18,000 tonnes (dry basis)
in year ten to treat predominantly high clay kimberlites. Intent is to install two additional 12 m
diameter CATS fed from a separate feed launder and distributor. Depending on the position of
the tailings discharge both lines will be used simultaneously (i.e., no standby line).

Pursuant to G.S. 143-215.6A(c), in determining the amount of the penalty I have taken into
account the Findings of Fact and Conclusions of Law and the factors set forth at G.S. 143B-
282.1(b), which are:
(1) The degree and extent of harm to the natural resources of the State, to the public Health, or
to private property resulting from the violation;
(2) The duration and gravity of the violation;
(3) The effect on ground or surface water quantity or quality or on air quality;
(4) The cost of rectifying the damage;
(5) The amount of money saved by noncompliance;
(6) Whether the violation was committed willfully or intentionally;
(7) The prior record of the violator in complying or failing to comply with programs over
which the Environmental Management Commission has regulatory authority; and
(8) The cost to the State of the enforcement procedures.
Within thirty days of receipt of this notice, you must do one of the following:
Submit payment of the penalty:
Payment should be made directly to the order of the Department of Environment and Natural
Resources (do not include waiver form). Payment of the penalty will not foreclose further
enforcement action for any continuing or new violation(s). Please submit payment to the
attention of:
Point Source Compliance/Enforcement Unit
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
OR
2. Submit a written request for remission or mitigation including a detailed justification
for such request:
Please be aware that a request for remission is limited to consideration of the five factors listed
below as they may relate to the reasonableness of the amount of the civil penalty assessed.
Requesting remission is not the proper procedure for contesting whether the violation(s)
occurred or the accuracy of any of the factual statements contained in the civil penalty
assessment document. Because a remission request forecloses the option of an administrative
hearing, such a request must be accompanied.by a waiver of your right to an administrative
hearing and a stipulation and agreement that no factual or legal issues are in dispute. Please
prepare a detailed statement that establishes why you believe the civil penalty should be
remitted, and submit it to the Division of Water Quality at the address listed below. In
determining whether a remission request will be approved, the following factors shall be

considered:
(1) whether one or more of the civil penalty assessment factors in NCGS 143B-282.1(b)
was wrongfully applied to the detriment of the petitioner;
(2) whether the violator promptly abated continuing environmental damage resulting from
the violation;
(3) whether the violation was inadvertent or a result of an accident;
(4) whether the violator had been assessed civil penalties for any previous violations; or
(5) whether payment of the civil penalty will prevent payment for the remaining necessary
remedial actions.
Please note that all evidence presented in support of your request for remission must be submitted
in writing. The Director of the Division of the Division of Water Quality will review your
evidence and inform you of his decision in the matter of your remission request. The response will
provide details regarding the case status, directions for payment, and provision for further appeal
of the penalty to the Environmental Management Commission's Committee on Civil Penalty
Remissions (Committee). Please be advised that the Committee cannot consider information that
was not part of the original remission request considered by the Director. Therefore, it is very
important that you prepare a complete and thorough statement in support of your request for
remission.
In order to request remission, you must complete and submit the enclosed "Request for Remission
of Civil Penalties, Waiver of Right to an Administrative Hearing, and Stipulation of Facts" form
within thirty (30) days of receipt of this notice. The Division of Water Quality also requests that
you complete and submit the enclosed "Justification for Remission Request." Both forms should
be submitted to the following address:
Point Source Compliance/Enforcement Unit
Division of Water Quality
1617 Mail Service Center
Raleigh, North Carolina 27699-1617

NPDES permit NoIN
Mitchell County
Dear Mr. Weaver,
By this correspondence, The Feldspar Corporation request renewal of its wastewater
permit NC 000353. Please fmd.attached the necessary forms required per your letter
dated July 7, 2005.
This permit is believed to be complete as submitted with the exception of the GCMS
testing that will be forwarded as soon as the test results are sent to us.
The water flow balance has variable numbers due to the nature of our water usage in the `
processing plants. We have been experiencing a period of declining sales and have not
operated one of our plants for almost a year. We are confident that this business will
return and we will need the capacities that we currently have permitted..
Should you have questions or need further information I can be contacted at 828-765-
8977 or you may also contact Tom Freeman at 828-765-8955.

Plant upset notification Follow-up
Dear Mr. Haynes
This correspondence is and follow-up to a notification call to your office on Thursday morning, February
24, 2004, concerning a high pH level in the effluent discharge to the North Toe River from our plant site
located at 530 Altapass Road in Spruce Pine, NC.
The high pH in the effluent was caused by a chunk of lime that fell into the ditch at our number 1 Plant.
The lime feeder discharges lime (used for neutralization) to a common ditch inside the plant which then
mixes before it travels to the wastewater treatment plant. The ditch had become clogged with rocks and
other debris and was being cleaned out by our maintenance crew. We had carefully monitored this
during the day and had worked with maintenance to assure there were no problems. At about 1430
hours, a chunk of lime came loose and entered the ditch before maintenance could stop it. This chunk of
lime broke,apart.as it traveled, to ithe wastewater plant causing the high pH. The pH was checked in the
spillway and was never measured at more than 11.1 standard units: The pH in the spillway did not get
high. until about 1500 hours:We assessed the situation and began diluting the high pH with the addition
of sulfuric acid. Special care was taken to prevent the pH from dropping too low. The high pH in the
effluent lasted about 1 hour before it came back into limits (10 SU). Stream samples were taken with the
following results upstream pH of 7.21 standard units and a downstream pH of 9.09 standard units.
The Feldspar Corporation regrets this situation occurred and will work to prevent its reoccurrence.
Should you have further questions about this matter or wish to discuss it further you can reach Plant
Manager Jerry Prosser or myself at 828-765-5500.
Sincerely,
The Feldsp C rpor

WATER QUALITY SECTION
ASHEVILLE REGIONAL OFFICE
This correspondence is and follow-up and clarification of the comment on the back of the DMR form for
November 2004. The Feldspar's wastewater plant is supplied with an ISCO bubbler flow meter, which is
located in the effluent channel. The flow was checked manually on. December 8, 2004 and the flow
meter was found to be reading high. The bubbler tube from the meter to the effluent channel was
clogged and was taken apart, cleaned placed back in service and checked against a manual measurement
which showed it was reading correctly.
The flow reading before the tube was cleaned was 2170 gpm and was 1155 gpm after the tube was
cleared. No other repairs or adjustments were made to the flow meter. This difference in the readings
would have made the correction factor 0.53. This factor was not applied to the flow readings due to not
knowing exactly when the tube actually became clogged. Checking this equipment will be added to our
routine maintenance perPomri each week to assure this problem does not reoccur.
Should you have further questions about this matter or wish to discuss it further you can reach me at
828-765-8955.

Dear Mr. Haynes

WATER QUALITY SECTION
This correspondence is and follow-up to a notification call to your office on Monday, January 10, 2005,
concerning an upset condition at our wastewater located at 530 Altapass Road in Spruce Pine, NC.
The Plants were down for repairs as is normal on Mondays and about 3:30 in the evening the electronics
engineer attempted to reprogram a computer at the No. 1 Plant resulting in the discharge of about 30+
tons of ground feed stock. This feedstock was in a hydrosizer and the recirculation pump was shut off
and this caused the material to be released to the wastewater plant. The materials then flowed to the
wastewater plant unannounced, which was shut down for repairs. The operator noticed the effluent was
beginning to become turbid and immediately called me and we began working on the problem. The pH
of the effluent was in the 7.2 to.7.3 standard unit range for the entire time. The turbidity was high (50

Notification Follow-up
Dear Mr. Haynes
This correspondence is and follow-up to a notification call to your office on Wednesday, December 15,
2004, and another call on December 16, 2004, concerning a discharge to the North Toe River from our
plant site located at 530 Altapass Road in Spruce Pine, NC.
The release of wastewater on December 15, 2004 occurred from the tailings tank near the North Toe
River. At about 0800 hours on Wednesday, December 15, 2004 the Plant #1 Supervisor called to inform
me that the tailings tank had overflowed for unknown reasons. The plant had been down overnight and
was just beginning to start up when the overflow occurred. The amount of water overflowing the tank is
unknown but only a small. amount of the overflow entered the river. Due to the startup of the plant there
was only the wet grinding circuit started and it was immediately shut down. The river was not visually
affected and the duration of the overflowing was less than 5 minutes. Although no stream samples were
collected I personally checked ,the downstream twice and could, see no visual effect. The back-up pump
could have been frozen due to the cold temperatures that morning because when it switched on it
overloaded the fuse, which shut it down. The pump was restarted and is operating normally now.
The Feldspar Corporation regrets this situation occurred and will work to prevent its reoccurrence.
Should you have further questions about this matter or wish to discuss it further you can reach Plant
Manager Jerry Prosser or myself at 828-765-5500.

Dear Mr. Freeman:
In your letter dated March 30, 2004 you informed us of an untreated wastewater discharge
occurring from the transfer tank located at 530 Altapass Road to the North Toe River. The
Feldspar Corporation holds no NPDES Permit authorizing this discharge. The Feldspar
Corporation is therefore in violation of North Carolina General Statute 143-215.1(a)(1) which
prohibits making an outlet into the waters of the State without first applying for and complying
with a permit from the North Carolina Environmental Management Commission. North Carolina
General Statute 143-215.69(b) provides civil penalties for discharging wastewater to the State's
surface waters without a permit.
A review of your file by the Division of Water Quality staff of the Asheville Regional Office
reveals a total of three unauthorized discharges from the transfer tank within the past six months.
This is way too many and we expect better of a major corporation. Within thirty days of receipt of
this letter please inform us, in writing, of your plans for upgrading this facilitiy which has been the
source of the unauthorized wastewater discharges at The Feldspar Corporation. We expect The
Feldspar Corporation to take whatever steps may be'necessary to properly contain wastewater
and implement any procedural changes necessary to stop these discharges.

Discharge to River
Dear Ms Price
This correspondence is and follow-up to a conversation (and notification) I had with Mr. Mike
Parker of your office on March 23, 2004, concerning a discharge to the North Toe River from
our plant site located at 530 Altapass Road in Spruce Pine, NC.
The accidental release of wastewater occurred at a transfer tank that is positioned near the
river. The tank is supplied with a primary pump and back up and both pumps were running but
the tank overflowed an estimated 400 —500 gallons at about 3 AM on the morning of 3-23-04.
An alarm alerted the wastewater plant operator to the problem and the Plant was shut down
until the problem was corrected. Nothing of major concern was found with either pump and
the plants started back at about 12 noon that day. Although we are not certain it is thought
that the pumps cavitated due to air because when they were shut off and restarted they both
worked fine.
The Feldspar Corporation's Plant Manager is currently in the process of requesting funds to
allow for an upgrade of the pumping system at the transfer tank. The Feldspar Corporation
regrets this situation occurred and will work to prevent its reoccurrence. Should you have
further questions about this matter you can reach me at 828-765-5500.

Discharge to River
Dear Mr. Parker,
This correspondence is and follow-up to a conversation (and notification) Tom Freeman had
with you on February 19 2004, concerning a discharge to the North Toe River from our plant
site located at 530 Altapass Road in Spruce Pine, NC.
The accidental release of wastewater occurred at a transfer tank that is positioned near the
river due to a power failure. The power failure kicked off all the electrical power to the plant
and the backup generator used to power the pump at the transfer tank started as it should
have, however for some unknown reason the main switch at Plant #2 kicked out. The water in
the pipe reversing the pump direction could have caused this, which would have overloaded the
motor and the breaker. The main breaker was turned back on and the pump was started within
10 minutes of the power outage. The water from the overflow of the tank caused the river to
become turbid for a short period of time and the riverbed was also stained with the heavier
solids in the area of the river near the plant.
As The Feldspar Corporation's interim Plant Manager I am in the process of requesting funds to
allow for an upgrade of the pumping system at the transfer tank. The Feldspar Corporation
regrets this situation occurred and will work to prevent its reoccurrence. Should you have
further questions about this matter you can reach Tom Freeman or myself at 828-765-5500.

Discharge to River
Dear Mr. Parker,
This correspondence is notification and follow-up to recent conversations
and a site visit you made, concerning a accidental discharge to the North Toe
River from our plant site located at 530 Altapass Road in Spruce Pine, NC. I
had called your office on January 14, 2004 to inform you of a discharge to
the North Toe River from the sump are below the plant and was also able to
reach you by cell phone. Later in the day you had stopped by and we visited
the site of the discharge.
On the morning of November 19, 2003 during a flood event the river and
storm runoff eroded part of a bank down stream of our plant area. This area
was a stormwater collection point and also served as an emergency holding
area and sump for spills or bypasses from the wastewater plant. The bank
was thought to be repaired on several occasions but has continued to give
problems and after holding water for a short period of time will begin to leak
through, and erode the embankment causing sediment to enter the stream.
The embankment was dug out completely and all fill materials removed
down to near the level of the river. Clay soils were used to construct the
embankment and several layers of fabric were used to assure its stability. I
spoke with David Baker of the US Army Corps of Engineers and was given
verbal approval to remove large rocks that had tumbled into the edge of the

stream. The construction is completed except for a safety berm and seeding,
which our contractor feels can be done in 2 weeks, weather permitting.
Stream samples were taken on January 14,2003 with the following results:

Spruce Pine, Mitchell County
Dear Mr. Parker,
On Wednesday, December 10, 2003 I called your office about 0900 hours to report that
the sump area below the plant, damaged by the recent flood and believed to be repaired
was allowing stormwater runoff to seep through the repaired area and wash sediment into
the North Toe River. After our initial discussion I updated you several times during the
day and was able to report about noon that the water causing the problem had been
diverted into a temporary pond area and was being pumped to the wastewater plant by a
portable pump.
The water in the river had become turbid when the stormwater was not contained in the
pond area and leaked through, washing an unknown amount of materials into the river.
The temporary pond and portable pump worked well stopping the discharge and are still
in place just in case they are needed. The sump area has been dug out and lined with
filter fabric and clay soils to assure its repair. These repairs should be complete by the
end of this week and the sump pump and pond area placed back into service.
The Feldspar Corporation feels the present repairs will be sufficient to contain the
stormwater collected in this area and will contact your office if problems arise. We regret
this incident happened and had taken steps to prevent it but found our repairs to be
inadequate. I can be contacted at 828-765-5500 if you have questions.

Dear Mr. Parker,
This correspondence is notification and follow-up to recent conversations with you and Mr. Roy
Davis of your office, concerning a accidental discharge to the North Toe River from our plant site
located at 530 Altapass Road in Spruce Pine, NC. I was on vacation at the time this was reported
and this letter is a follow-up to my conversation with Mr. Davis on Monday evening, November
24, 2003.
On the morning of November 19, 2003 during a flood event the river and storm runoff eroded
part of a bank down stream of our plant area. This area was a stormwater collection point and
also served as an emergency holding area and sump for spills_ or bypasses from the wastewater
plant. The bank was repaired on the 20'' and 21" but was not used or tested until Sunday night
when a small amount of water from a pump overflow, made its way to this area. A portion of that
water leaked through the bank and entered the river. One of our employees saw this and the
operator stopped the water from flowing to this area. It was dark and no assessment of the
situation could be made. On Monday morning after the plants were shut down for repair day, the
pump overflowed again (but was quickly repaired) and the bank once again leaked water through
to the river. The assistant ORC reported to me that the River was slightly turbid due to this
discharge, but was clear by about 0915 that morning. The bank was dug out in the area of the
leak and repaired by packing materials onto the bank.
The Feldspar Corporation regrets this situation occurred and will work to prevent it's
reoccurrence. Should you have further questions about this matter you can reach Jim Taipale or
myself at 828-765-5500.

Discharge to River
Dear Mr. Parker,
This correspondence is notification and follow-up to recent conversations with you and Mr. Forrest
Westall of your office, concerning a discharge to the North Toe River from our plant site located at 530
Altapass Road in Spruce Pine, NC.
On the morning of November 16, 2003 Mr. Forrest Westall called me at home to inform me that there
was a problem with the color of the river below The Feldspar Corporations operations on Altapass. After
calling to the wastewater treatment plant I was informed that the effluent water was good and they did
not know of any problems. A daily grab sample taken at 2 AM showed the turbidity of the effluent to be
17 NTU, at that time. Mr. Ronnie Presnell visually checked the river downstream and found the river
water to be turbid near the down town area. The water in the river near the plant was clear. I called Mr.
Westall to confirm the report he had received and told him I would also call him back after he returned
from church (that evening) to let him know of the source. I left a message for him at 13:20 that
evening.
The accidental release of solids occurred at a transfer tank that is positioned near the river due to solids
and excessive flow. There was a problem with the drying circuit in Plant No. 1 at about 0430 hours
which placed excessive solids and flow into this transfer tank. The excess caused the tank to overflow
and allow the partially untreated water to enter the North Toe River. The water had been neutralized but
not clarified. The water from the overflow of the tank caused the river to become turbid for a.short
period of time and the riverbed was also stained with the heavier solids in the area of the river near the
plant.
The Feldspar Corporation Plant Manager is in the process of requesting funds to allow for a back up
pumping system to handle upset conditions that may cause surges in the wastewater system.
The Feldspar Corporation regrets this situation occurred and will work to prevent its reoccurrence.

Dear Mr. Parker,
This correspondence is a follow-up to your August 15, 2003 visit to The Feldspar Corporations
Plant site on Altapass road regarding a citizen complaint. The unknown complainant had listed
four things three of which were answered in a letter to your office on July 31, 2003.
In you correspondence dated August 28, 2003 you requested a reply in writing as to how we will
comply with the items in section B of your letter. Please find listed below the course of action for
each item listed.
1. Concrete wall at Plant #2 adjacent to the fluoride tanks had weakened with age and had
fallen. This wall has been reconstructed and any water collected on the pad is directed to
a sump where it is pumped to the wastewater system.
2. A BUT plan for the low area at the bridge and the road leading to this area has been
prepared and is attached. The present basin is being maintained but there is a large
amount of work involved in enlarging the basin and controlling the runoff from the
roadway. We are obtaining bids from contractors now and will begin the upgrade as soon
as the funding is approved at the corporate level.
3. The seal water from the two Pumps behind plant #2 is being re-routed to the wastewater
collection system. This should be completed by October 1, 2003
The Feldspar Corporation feels these complaints are not from a concerned citizen but rather
someone who is upset with The Feldspar Corporation due to employment or business matters.
The Feldspar Corporation will continue to look for ways to improve our runoff collection and
wastewater treatment systems. If you need further information I may be reached at 828-765-
5500.

NPDES Permit NwA,�N000Qe:353�
Mitchell County
Dear Mr. Freeman:
As I discussed with you on August 15, ,2003; the reason for my visit was the result of a
complaint, which had been received by the U.S. Environmental Protection Agency in Atlanta and
forwarded to the Division of Water Quality for review. The complaint listed the following items of
concern: (a) The Feldspar Corporation was operating with an expired NPDES Permit, (b) wastewater
from the fluoride tanks outside plant No. 2 are allowed to overflow and subsequently flow into the
North To River untreated, (c) the wastewater flow rates are in excess of what is permitted in the
NPDES Permit and (d) wastewater from the Unimin Crystal ,Plant is allowed to enter the North Toe
River without treatment.
The inspection revealed the following: (a) The Feldspar Corporation is operating with an
expired NPDES Permit. NPDES Permit No. NC0000353 expired on December 31, 2001. An
application for renewal of this permit was received by the Division of Water Quality on July 10, 2001.
Due to several factors such as staff turnover, the Division of Water Quality has not reissued the
permit; however, draft NPDES Permit information is currently being reviewed by EPA. The
Company, as outlined in the expired permit, is to continue to operate under the expired permit until
a new permit is issued. The company is not in violation of having an expired permit. (b) A review of
the fluoride tanks behind Plant No. 2 found that a concrete wall approximately 12 inches high had
fallen off the south side of the concrete pad. This wall could prevent the loss of any contaminated
water that could collect on the concrete pad and make its way to the North Toe River. It is
recommended that this concrete wall be replaced. Also, you indicated that the sump pump which
collects water from this area is checked a minimum of 2 times per shift by the wastewater treatment
plant operators. It is also recommended, that Best Management Practices (BMP's) be installed in
a low area below the sand tanks near the bridge crossing to control stormwater. The seal water from
the two pumps adjacent to the road below Plant No. 2 should be collected and pumpthe

wastewater treatment system. (c) Based on the monitoring data there is no indication that the
wastewater flow rates are in violation of NPDES Permit requirements. (d) During the inspection I
walked the wastewater line coming from the Unimin Crystal Plant and could not find any leaks or
discharges in the wastewater piping or any indication that their wastewater was not being properly
treated.
It is requested that you respond in writing by October 1, 2003, as to how you will comply
with items listed in section (b).

Subject: Citizen Complaint to EPA
The Feldspar Corporation
Spruce Pine, Mitchell County, NC
NPEDS Permit No.INC0000353 :
Dear Mr. Parker,
This correspondence is a follow-up to our conversation on July 28, 2003 concerning the
complaint of a citizen through the EPA's Atlanta office. In you e-mail message on the
29'' you requested a response to these complaints.
We have two 18,000-gallon tanks at the south end of our No. 2 processing plant, which
neutralize and treat the fluoride bearing wastewater from our processing plants. The
tanks are located on a walled, concrete pad placing them inside a containment area. The
containment area drains to a smaller containment (pumping) area, which has a sump
pump that pumps back to the tanks. Flow to the sump area is metered (by pipe sizing)
and the sump pump is of more than adequate size to handle the flow. The water that
would overflow to this sump in an overflow situation would be would be neutralized and
not "high pH water " as alleged in the complaint. This area is checked a minimum of 2
times per shift by the wastewater plant operator and in speaking with them the last time
any overflow was observed was on June 26, 2003 when some leaves and debris had
choked the sump pump and had to be cleaned out (the pump was fixed by maintenance
personnel in less than 10 minutes). These tanks have not been overflowing and running
into the river but to assure the quickest response to any possible spill or overflow in this
area we will install a level sensor that will alert the operator (at his workstation) to
possible overflows or high water levels in the sump containment area. We are currently
examining a new system that would collect all of our process waste streams into a new
sump with level control and excess flow pumping capabilities. This new system would
allow us to handle additional excess inflows from storms and process overflows. This
new system is in the engineering phase and would also require submittal of an
authorization to construct (with approval from your office) before the construction could
be considered.

An Isco 4230 bubbler meter measures the effluent flow from the wastewater plant and
was calibrated in April of this year. I am not sure what the statement "flow rates are too
high" actually means but if this citizen knew our permitted flow requirements of 3.5
MGD and calculated the influent flow, the numbers would be out of balance due to the
amount of recycle water we use. The E-cat clarifier is designed for 3800 gpm, which
calculates to 5 MGD but this flow amount does not reflect our recycle water usage.
The Feldspar Corporation feels these complaints are not correct but will continue to look
for ways to improve our wastewater collection and treatment. We also regret any undue
work this may have caused your office. If you need further information I may be reached
at 828-765-5500.

Dear Mr. Parker,
JUN - 6 2003 �t
r B
This letter is a follow-up to our conversations last week concerning a high turbidity in the effluent
discharge on the evening of May 14, 200 from the above facility. The problem was found,
corrected and the necessary follow up performed. As we discussed in our phone conversation,
the problem was a spike in the turbidity of the effluent.
During the early morning of the 10 the 40' clarifier had gone down and maintenance was in the
process of draining the clarifier to make necessary. repairs. This increased the loading to the 35'
clarifier and the shift operator did not adjust the rate of polymer properly. This operator is new to
our department and did not notice the high turbidity from the 35' clarifier. I discovered the high
turbidity (80 NTU at the spillway) at about 2:35 in the evening and called your office and spoke
with Keith Haynes. I also checked the river for clarity and found it to be slightly turbid to just
below town. The effluent suspended solids for the day was in the normal range. I estimate the
time of the turbid effluent was between 30 and 45 minutes with the effluent turbidity getting
gradually worse. The effluent was back to 25 NTU by 3 PM and the problem identified and
corrected.
The Feldspar Corporation regrets that this has taken place and has taken steps to correct this
problem. If you have questions concerning this matter I may be reached at 828-765-5500.

APR - 2 2003
This correspondence is a follow-up to our conversation on Tuesday 3-25-03 concerning an unknown
amount of wastewater overflowing a tank and entering the North Toe River.
About 1250 PM on 3-25-03, a mechanical problem caused a pump at the tailings tank to shut down and the
backup pump took 3 to 5 minutes to begin pumping the water in the tank. This caused the wastewater in
the tank to begin backing up and eventually an unknown amount (estimated at <400 gallons) overflowed
into the river. Plant No.1, the source of the wastewater was immediately shut down and the system was
repaired and checked for further problems before the plants restarted later in the evening.
No visible effects were observed in the stream except near the entry point at the plant area. No stream
samples were collected due to the lack of visible impact after I visually inspected the river two times.
The Feldspar Corporation regrets this incident happened and will continue to take steps to prevent
reoccurrence. If you have questions I can be reached at 828-765-8955.

Dear Mr. Parker,
This correspondence is a follow-up to our conversation on today concerning a plant upset at our wastewater
facility on Altapass road in Spruce Pine.
At about 1000 hours today the E-CAT clarifier and thickener began to produce water that was turbid. The
E-CAT has a short detention time and can normally be turned around or corrected in about 20 to 30
minutes. The bed level in the clarifier had climbed too high and was carrying small solids over the weir
due to the flow hydraulics and the exposed bed level. One of the high alarms did not operate properly and
the bed was actually higher than the operating system showed. Because the system did not respond to
normal corrections the plants were shut down to allow the bed level to be reduced to normal levels. During
this time the other clarifiers continued to operate at their normal clarity. The bed level had dropped to
normal by 1500 hours and one plant was placed back into operation.
Stream samples were collected up stream and down stream to measure the effects of the upset. The
samples were taken after the plant upset was corrected with sample results as follows:
Parameter Upstream Downstream
PH 6.87units 7.35 units
Turbidity 9.6 ntu 12/11 ntu
Fluoride and Suspended solids results will be run at a later date.
The Feldspar Corporation regrets this incident happened and will continue to take steps to prevent
reoccurrence. If you have questions I can be reached at 828-765-5500

Dear Mr. Parker,
As a follow-up to our conversation on 12-2-02 this correspondence will explain the Plant upset the
occurred at the above facility November 25, 2002.
I was on Vacation and was called in by one of the assistant operators at about 8:10 in the evening on the
25`h. The automated polymer mixing system had failed to mix and the operator had not noticed this lap in
treatment. For some unknown reason the fresh water used to mix the polymer had been replaced by recycle
water (backup system). Due to the lack of polymer treatment the effluent water became turbid and once the
mixing system was repaired by the electricians the polymer was mixed with recycle water. The polymer
was not effective due to the recycle water and fresh water was used to manually mix the polymer until the
mixing system and lines were flushed and brought back on line. The effluent water was back to normal by
9:10. Several steps have been taken to prevent the reoccurrence of this upset. Recycle water will only be
used in emergency situations. On Tuesday Morning I talked to Keith Haynes of you office and reported
this upset.
I also talked to Lucy Smith of your office on Wednesday, November 27, 2002 to report that a pump failure
had caused an unknown amount of untreated water to enter the North Toe River. Someone either cut the
pump off or there was an electrical problem, which caused the pump to stop. The assistant ORC restarted
the pump and stream samples were taken which showed no effect to the stream.
The Feldspar Corporation regrets these upsets occurred and will take appropriate actions to assure they do
not reoccur. If you have questions concerning these matters, I can be reached at 828-765-5500.

This correspondence is a follow-up to our telephone conversation on October 2, 2002 concerning
a pipe leak at the above facility.
At approximately 8:10 am on the morning of October 8, 2002, a contractor for The Feldspar
Corporation was blading a road and scraped a pipe carrying water from Unimin's Crystal Plant to
The Feldspar Corporation's wastewater plant. The pipe was a heavy plastic pipe (SDR) and the
scrape allowed 4 to 5 gallons of water to leak out of the pipe. The water was clear (estimated at
<10 NTU) and the pH was measured at 7.9 units. The water that leaked from the pipe traveled
down the road and into the river. The flow to the river was estimated at a maximum of 225
gallons. The flow was diverted to a secondary pipe at 8:25 am and the primary pipe repaired
before being placed back into service. Water entering the North Toe River did not change the
appearance of the water nor cause any visible damage.
The Feldspar regrets that this incident happened but is pleased with the response our employees
gave to identify the problem and complete the repairs with minimal environmental harm. Care
will be used when instructing contractors on how to blade this road in the future. Should you have
questions concerning this matter I can be reached at 828-765-5500.

Dear Mir. Parker,

This correspondence is a follow-up to our conversation on Wednesday 8-21-02 concerning an unknown
amount of wastewater overflowing a tank and entering the North Toe River.
Some time after 11:15 AM on 8-21-02 an electrical wire in the control box for the tailings pump shorted
out due to vibration and the loss of insulation from the wires. This pump, located near the river has a back-
up system, which worked but one valve control also shorted out causing the backup system to ptunp back
through the stalled pump. This caused the wastewater in the tank to begin backing up and eventually an
unknown amount overflowed into the river. Plant No.1, the source of the wastewater was immediately shut
down and the system was repaired and checked for fitrther problems before the plants restarted later in the
evening.
Stream samples were collected although no visible effects were observed in the stream except near the
entry point at the plant area. The stream samples were collected at the normal collection sites at the
following times: Upstream 1339 hrs, Downstream 1326 hrs. The sample results were:
Parameter Upstream Downstream
PH 7.74 units 7.47 units
Turbidity 3.4 ntu 4.6 ntu

Subject: Low effluent pH
The Feldspar Corporation
NPDES No:,t-iC0.000353
Spruce Pine, Mitchell County
Dear Mr. Parker,
This letter is a follow-up to our conversations this week concerning a low pH in the effluent
discharge on the morning of May 16, 2001. The problem was found, corrected, investigated and
the necessary follow up performed in the absence of the ORC. As we discussed in our phone
conversation,l don't feel that the problem was anything other than a dip (spike) in the pH level of
the effluent and not something that occurred over along' time period.
During the early morning hours of Wednesday, May 16, 2001 the motor on a polymer pump at
the wastewater plant failed and necessitated the shut down of the production plants. During that
time the operator at plant #1 spilled approximately 0.5 gallons of sulfuric acid by overflowing a
day tank. Because the plants were down there was no mixing or absorption of this reagent and
the low pH water would have passed the automated lime feeders as a spike without causing great
change in the lime addition. This allowed the spike to travel through the wastewater plant and to
the effluent.
At 7:30am a grab sample showed the effluent pH was 4.5 units. At 8:05am downstream samples
showed a Ph of 6.62 units and at 8:09am the upstream pH was 6.83units. Another effluent grab
sample was taken at 8:20am, which showed a ph of 6.02 units. At 8:55am another effluent grab
sample was analyzed which showed a pH of 6.61units.
The Feldspar Corporation regrets that this has taken place and has and will be taking steps to
correct this problem from reoccurring again...Please feel free to contact myself or plant manager

Dear Mr. Parker,

ASNEVILLE ICI GI NAL OFFICE
This correspondence is a follow-up to our conversation today concerning a pipe break at
the above facility.
A contractor was excavating an area near the effluent pipe and accidentally hooked a join
in the 24" CMP pipe that leads from the wastewater plant to the North Toe River. The
pipe then began leaking water around the break that ran into the ground. The water
leaking from the pipe seeped into the ground and into an old buried pipe causing sand to
be washed into the river. The process plants were down and the water was quickly turned
off and the pipe repaired.
The old pipe will be plugged and/or removed on Tuesday to prevent this from
reoccurring. The Feldspar Corporation regrets this accident happened and any harm
caused to the river appears to be minimal.
I can be reached at 828-765-5500 if you have questions.
Sincerely,

Mike,
Per our conversation last week we are continuing with our plans to begin operation of the new wastewater system
as described in the approved ATC. After a meeting with operators the system will be started on Tuesday 1-29-02. 1
called your office and left a message stating this is the required 48 hour notification.
Our engineer has signed the certification and I will mail that to Raleigh today.
We expect a week or more will be required to get the system fully operational. When we get to full operation I will
be glad to notify you, if you desire.
Please call me at 828-765-5500 if you have questions.

Dear IVIr. Freeman:
The NPDES Unit personnel received your permit renewal application on July 10, 2001. Thank you for
submitting the package.
The permit renewal for this facility will be assigned to a member of the NPDES Unit staff. The NPDES
Unit has been working with at least 2 (and as many as 5) vacant positions since October 1998. This staff shortage is .
delaying all of our permit renewals. While we do not expect severe delays in processing your permit renewal, be aware
that your permit is one of many our staff is currently reviewing. .. Z.
If this staff shortage delays reissuance of NC0000353, the existing requirements in your permit will remain in
effect until the permit is renewed (or the Division takes other action). We appreciate your patience and understanding
while we operate with a severely depleted staff. If you have any additional questions concerning renewal of the
subject permit, please contact me at [phone], extension 520.

Supplemental Documentation
Present Operating Status:
The Feldspar Corporations, Wastewater Treatment Facility operates at or
below capacity and is at present in compliance with the requirements of the
NPDES Permit.
The present system has been built over the last 40+ years as the plant has
expanded in size and production of finish products. The 35'diameter, 8'
deep clarifier (57,726 gal. capacity) and a disk filter was placed into service
in the early sixties and a 40' diameter, 10' deep clarifier (94,247 gal.
capacity) and another disk filter was placed in service in 1972. A 55'
clarifier, 12' deep (213,824 gal. Capacity) was placed into service in 1986
along with two 18,000-gallon equalization tanks.
Potential Facility Changes:
The plant is now undergoing an upgrade that includes like for like
replacement of the disk filters, electrical and a new building. Attached is a
letter to Mike Parker of the Asheville regional office.
The Feldspar Corporation applied March for Authorization to Construct
(ATC) a new Eimco, Clarifier and Thickener (E-CAT) and a stand-by pump
and generator for a tailings tank located near the North Toe River. The ATC
was approved on June 29, 2001 and the equipment has been ordered to allow
construction before cold weather and years end.
Schematic of wastewater flow:
Please see attached flow drawing.
Location Map:
Please see attached USGS print-outs.
Production Data:
Applicable production date as required by 40 CFR does not apply to this
facility.
Priority Pollutant Analysis:
PPA results will be forwarded when completed.

Dear Mr. Parker,
This letter is a follow-up to our conversations over the last several months about the need
to replace the building and certain equipment at the wastewater treatment plant here at
The Feldspar Corporation's, Spruce Pine, NC location.
We are currently awaiting approval of an authorization for expenditures (AFE) that will
allow funding for this facility up -grade. The big items include the addition of a stand-by
pump and generator for the tailings tank located at the river bridge and the addition of an
Eimco E-CAT clarifier and thickener. An authorization to construct (ATC) covering
these items has already been sent to the Raleigh Water Quality office for approval. The
AFE will also cover other improvements such as an upgrade of the electrical system and
replacement of certain equipment items. The electrical system at the wastewater plant
was installed in sections from the 1960's until the present. New motor control centers
will be installed to replace the existing electrical,system.

The Don Oliver and Denver disk filters are worn and will be replaced with Eimco disk
filters. The Eimco filters will also allow us to stock spare parts for one filter rather than
two. Placement of the new Eimco filters will be configured to allow plant operations to
continue during installation. Conveying systems and other items associated with the disk
.filters will be added and modified, as necessary, to allow for continued plant operations
during equipment placement.
Due to age, the buildings of the wastewater treatment plant will be replaced with a steel
frame and sheet metal structure requiring temporary removal of the plant operators'
office and lab. The lab will be split into two parts: one will be located in the temporary
plant operators' office in the parking area of plant number two and the other will be
located in the research lab near the main office. Grab samples will be analyzed and
stored at the.lab located in the temporary operators' office. Composite samples will be
analyzed and stored in the temporary lab located in -the research lab. The new office and
lab will house a state of the art operating system that will allow- the plant to be operated

NPDES Permit No. NC 0000353
Dear Sirs,
The Feldspar Corporation, by this...correspondence,..requests..approval of the -attached
Authorization to Construct (ATC). The authorization to construct will allow The
Feldspar Corporation to upgrade the Spruce- Pine..processing-plants wastewater. treatment
facilities.
The ATC requests the addition of major components- (1�.A.duel pumping system with
stand-by generator; (2) The addition of a Clarifier / Thickener. (Eimco E-CAT) for
improved clarification and solids handling capacity. '
Pump System with Stand-by Generator
Wastewater (tailings) from Plant No. 1. flows by, gravity to. a.tank. (commonly known as
the tailings tank) located near the North. Toe River. The wastewater is then pumped from
this collection tank to the wastewater treatment..plant-._ -failure of the existing

pumping system (mechanical, electricals.etc-)...hasthe..patential_to release wastewater to
the North Toe River. This system was built in 1960 as part of a solids collection system
to prevent the plant effluent from being- straight_piped_to.:the..stream.
To provide a working system that represents the best available control technology will
requires the addition of a second pump -with -the -ability -to. supply alternate -electrical
power to the pumping system. Electrical power failures are the most likely contributor to
a potential spill. Plant No. 1 has the potentiallo-generate 1800 gallons of wastewater per
minute and, because the system is gravity fed, drainage from the plant can continue after
the pump has stopped. Sensors will automatically...acti_vate.the.stand-by generator in the
event of a power failure or if the wastewater. level rises in the tank for any reason.
Alarms will alert the plant operator if_the.stand-hy. generato -is. activated-.. The.alarm will
also be indicated on a PC located in the wastewater treatment plant operations room.
Plant operators will be able to open and close_valvess.start.and.stop pump. motors,. and test
the generator from the operations room.
The duel pump set-up is to provide redundancy. to -assure ...adequate pumping..capacities of
the flows expected from Plant No. 1 under all circumstances, as well as facilitate pump
maintenance.
Addition of Clarifier / Thickener,
The original wastewater plant was. constricted_in_the..L960.'s..and subsequentLy expanded
with evolving permit requirements, laws, regulations, and production demands. This
worked very well until an upgrade of our_.No._Lplant pro-vided.a sharp increase.in
production tonnages and use of feedstock. Two years ago our engineering group began
looking into how we could effectively increase -the capacity of our wastewater treatment
facility. Due to the location of our plants, Altapass Road and the North Toe River, the
first obstacle to overcome was the placement ...of -the ..additionaL clarifier.

ATC Request Letter
After researching the location of the new..equipmentr.we..were.faced with. finding a
wastewater treatment unit that would fit in a very small footprint. We found through
research that Eimco (a division of Baker..Hughes)..had.bought_.the rights to a South
African patented treatment system that combines thickening and clarification. This unit
is known as the Eimco — Clarifier and Thickener. (E!CAT)._.Eighty-two units are now
operating in six countries with excellent results. The E-CAT has the benefits of a high
rate thickener with a footprint 10% the..size_o£a_conventional-clarifier, making. it the
perfect fit for our needs.
In the spring of 1998 Eimco and The Feldspar..Corporation.performed a series. of pilot
plant test at The Feldspar Corporation's Spruce Pine Facility. This was the first study
performed in the United States and Gerrit.du..Plessis,Eimco.'.s.E-CAT expert was flown
in from South Africa to conduct the test. After operating the.pilot plant for eight days,
the desired results were achieved. In..the-Fall..of2.010,1-was.able to observe the, potential
of the E-CAT during a visit to Val D'or, Canada, where Agnico-Eagle, a gold mining and
refining facility has 6 E-CATS in use. They needed.six_120'diameter conventional
clarifiers to treat the waste streams and chose the six E-CATs for their footprint. We
talked with other facilities that have E-CATs. and -they. all -stated that the E-CAT is
working above and beyond their expectations. Based on the good pilot plant results here
and the favorable experience of those who. have_recentLy. employed this technology we
are now ready to place a 10-meter E-CAT into operation at the Spruce Pine facility.
Construction activities to be covered..bXthe..ATC..as..pertains_to the placing. of the E-CAT
are as follows:
Construction of the E-CAT
Construction of the associated collection and distribution boxes
Construction of the associated pumping and piping
Connecting and interfacing with existing system
Electrical service, distribution and instrumentation

CONSTRUCTION SEQUENCE PLAN
Both the placement of a second pump and the construction of the Eimco E-CAT clarifier
are add-ons to the present system and are not expected cause any interruptions in
operations.
The .collection tank near the river will be upgraded by adding a back-up pump and a
stand-by generator as follows:
• Apply to Water Quality section for Authorization to Construct and receive
approval.
• The pump house will be enlarged to accommodate the secondary pump by
pouring a concrete floor in the expansion area. The wood frame building will
them be expanded.
• The new 8X8 ASH (Allen Sherman Hoff) slurry pump (pump no. 2), supplied
with a 100 HP motor will be installed.
• Pump no. 2 supply line from the tank will be added along with the automated
valve and plumbed to the new pump.
• The discharge of pump no.2 will be plumbed into the existing piping leading to
the wastewater plant and supplied with an automated valve.
• The original pump (pump no. 1) will be fitted with automated valves and new
lines and readied for service.
• Final electrical hook-up to the new automated switches, valves, and stand by
generator will complete this part of the project.
The construction of the building will be done as weather permits and the equipment and
electrical hook-ups will be made on repair days. We have historically shut all operations
down on Mondays (or Tuesdays) of each week for repairs that cannot be made while the
plant is in operation. This allows for repairs and installation of major equipment and
electrical components such as the ones discussed above.

The Feldspar Corporation
Spruce Pine, NC
Mitchell County
NPDES # NC0000353
The construction of the Eimco E-CAT will be scheduled as follows:
• Apply to Water Quality section for Authorization to Construct and receive
approval.
• Order E-Cat from Eimco and issue purchase.
• Prepare area for E-CAT concrete footer, foundation and associated splitter box
support, and pour concrete.
• Construct connecting stairway for E-CAT and splitter box and begin (dry)
plumbing.
• Construction of E-CAT by Eimco construction crew.
• Installation of electrical components and instrumentation.
1 Final plumbing tie-ins to splitter box, underIlow pumps, and disk filters.
• The 40' and 35' clarifiers will be left to operate as they do now until the E-CAT is
fully operational as a standalone unit.

PART IV - EVALUATION AND RECOMMENDATIONS
The Feldspar Corporation has requested renewal of NPDES Permit
Number No. NC0000353 for the continued discharge of industrial
process wastewater from the production of feldspar, mica and sand
at their plant at Spruce Pine, North Carolina.
There are no effluent guidelines for this industry and the
effluent limitations were developed using production and process
information and the North Carolina Water Quality Standard of 1.8
mg/l. There are four other companies, K-T Feldspar Corporation,
Unimin Corporation -Quartz, Unimin Corporation -Crystal and Unimin
Corporation -Schoolhouse Quartz Operation which have similar
industrial processes and wastewater characteristics. Each company
discharges or proposes to discharge fluorides to the North Toe
River. It has been determined that there is a maximum
assimilative capacity of 574 lbs/day of fluoride in the North Toe
River at the mouth of Little Bear Creek. All five permits are
interdependent on each other because the total assimilative
capacity of the fluoride is allocated between the five industries
and all permits should be issued at the same time.
The discharges from 002 and 003 is non contact cooling water.
At the time of the staff report an new clarifier/thickner is being
installed at the wastewater treatment facility. Two new vacuum
filters are also being installed to replace the existing units.
Also, at the main wastewater lift station a second pump and
emergency generator is being installed. There have been no
changes in the wastewater characteristics or discharge since the
permit was last issued.
There have been several exceedances for fluoride and pH over the
past three years. The new wastewater treatment units should help
with these permit violations. Notices of violation were sent for
these minor violations.
At -this writing The Feldspar Corporation has not submitted the APA
data but will submit the data when analyses.nis complete. {

It is recommenaed that the permit be permit be issued with"the
existing limits and monitoring requirements.

SUMMARY OF FACILITY INFORMATION AND WASTELOAD ALLOCATION
The Feldspar Corporation is requesting a permit renewal for its industrial minerals processing
facility. The facility is permitted to discharge into the North Toe River, class C=Trout waters, in
French Broad River Basin. Currently the Unimin Corp. -Crystal Plant (NC0084620) effluent
discharge also goes to the Feldspar Corporation WWTP. Outfall 001 discharges the treated process
water and outfalls 002 and 003 discharge cooling water.
(see attached memo on North Toe Mines)
The existing wastewater treatment plant consists of:
• three clarifiers,
• polymer feed system,
• Lime feed system for pH adjustment,
• Vacuum filters,
• Emico clarifier/thickener,
• Pump station emergency generator,
• flow measuring and totalizing equipment and
• two recycle pumps.

STORMWATER MONITORING, CONTROLS AND LIMITATIONS FOR PERMITTED DISCHARGES
FINAL LIMITATIONS AND CONTROLS FOR STORMWATER DISCHARGES
During the period beginning on the effective date of the permit and lasting until expiration, the
Permittee is authorized to discharge stormwater associated with industrial activity. Such discharges
shall be controlled, limited and monitored as specified below.
Stormwater Pollution Prevention Plans
The Permittee shall develop a Stormwater Pollution Prevention Plan, herein after referred to as the
Plan. The Plan shall be considered public information in accordance with Part II, Standard Conditions,
Section E.10. of this permit. The Plan shall include, at a minimum, the following items:
a. Site Plan: The site plan shall provide a description of the physical facility and the potential
pollutant sources which may be expected to contribute to contamination of regulated
stormwater discharges. The site plan shall contain the following:
(1) A general location map (USGS quadrangle map, or appropriately drafted equivalent map), showing the
facility's location in relation to transportation routes and surface waters, and the name of the receiving
water(s) to which the stormwater outfall(s) discharges. If the discharge is to a municipal separate storm
sewer system, the name of the municipality and the ultimate receiving waters, and accurate latitude and
longitude of the point(s) of discharge must be shown.
(2) A narrative description of storage practices, loading and unloading activities, outdoor process areas, dust or
particulate generating or control processes, and waste disposal practices.
(3) A site map (or series of maps) drawn to scale indicating the location of industrial activities (including
storage of materials, disposal areas, process areas, and loading and unloading areas), drainage structures,
drainage areas for each outfall and activities occurring in the drainage area, building locations and
impervious surfaces, existing BMPs, and the percentage of each drainage area that is impervious. For each
outfall, a narrative description of the potential pollutants which could be expected to be present in the
regulated stormwater discharge.
(4) A list of significant spills or leaks of pollutants that have occurred at the facility during the 3 previous years
and any corrective actions taken to mitigate spill impacts.
(5) Certification that the stormwater outfalls have been evaluated for the presence of non-stormwater
discharges. The certification statement will be signed in accordance with the requirements found in Part II,
Standard Conditions, Section B.11.
b. Stormwater Management Plan: The stormwater management plan shall contain a narrative
description of the materials management practices employed which control or minimize the
exposure of significant materials to stormwater, including structural and non-structural
measures. The stormwater management plan, at a minimum, shall incorporate the following:
(1) A study addressing the technical and economic feasibility of changing the methods of operations and/or
storage practices to eliminate or reduce exposure of materials and processes to stortnwater. Wherever
practical the Permittee should consider covering storage areas, material handling operations, manufacturing

Permit NC0000353
or fueling operations to prevent materials exposure to stormwater. In areas where elimination of exposure
is not practical, the stormwater management plan shall document the feasibility of diverting the stormwater
runoff away from areas of potential contamination.
(2) A schedule to 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 materials 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 prior to release of the accumulated stormwater. Accumulated stormwater shall be
released if found to be uncontaminated. Records documenting the individual making the observation, the
description of the accumulated stormwater and the date and time of the release shall be kept for a period of
five years.
(3) A narrative description of Best Management Practices (BMPs) to be considered such as, but not limited to,
oil and grease separation, debris control, vegetative filter strips, infiltration and stormwater detention or
retention, where necessary. The need for structural BMPs shall be based on the assessment of potential of
sources contributing significant quantities of pollutants to stormwater discharges and data collected through
monitoring of stormwater discharges.
(4) Inspection schedules of stormwater conveyances and controls and measures to be taken to limit or prevent
erosion associated with the stormwater systems.
c. Spill Prevention and Response Plan: The Spill Prevention and Response Plan shall incorporate
a risk assessment of potential pollutant sources based on a materials inventory of the facility.
Facility personnel (or team) responsible for implementing the plan shall be identified in the
plan. A responsible person shall be on -site at all times during facility operations that have the
potential to contaminate stormwater runoff through spills or exposure of materials associated
with the facility operations.
d. Preventative Maintenance and Good Housekeeping Program: A preventative maintenance
program shall be developed. The program shall document schedules of inspections and
maintenance activities of stormwater control systems, plant equipment and systems. Inspection
of material handling areas and regular cleaning schedules of these areas shall be incorporated
into the program.
e. Training schedules shall be developed and training provided at a minimum on an annual basis
on proper spill response and cleanup procedures and preventative maintenance activities for all
personnel involved in any of the facility's operations that have the potential to contaminate
stormwater runoff. Facility personnel (or team) responsible for implementing the training shall
be identified in the plan.
The Stormwater Pollution Prevention Plan shall identify a specific position(s) responsible for
the overall coordination, development, implementation, and revision to the Plan.
Responsibilities for all components of the Plan shall be documented and position(s) assignments
provided.
g. Plan Amendment: The Permittee shall amend the Plan whenever there is a change in design,
construction, operation, or maintenance which has a significant effect on the potential for the

Permit NC0000353
discharge of pollutants via a point source to surface waters. At a minimum, the Stormwater
Pollution Prevention Plan shall be reviewed and updated on an annual basis.
The Director may notify the Permittee when the Plan does not meet one or more of the
minimum requirements of the permit. Within 30 days of such notice, the Permittee shall submit
a time schedule to the Director for modifying the Plan to meet minimum requirements. The
Permittee shall provide certification in writing (in accordance with Part II, Standard Conditions,
Section B.11.) to the Director that the changes have been made.
h. Facility Inspections: Inspections of the facility and all stormwater systems shall occur at a
minimum on a semiannual schedule, once in the fall (September - November) and once during
the spring (April - June). The inspection and any subsequent maintenance activities performed
shall be documented, recording date and time of inspection, individual(s) making the
inspection and a narrative description of the facility's stormwater control systems, plant
equipment and systems. Records of these inspections shall be incorporated into the Stormwater
Pollution Prevention Plan.
Visual monitoring as required in Part I, Section B.3.b. shall be performed in addition to facility
inspections.
i. Implementation: Implementation of the Plan shall include documentation of all monitoring,
measurements, inspections, maintenance activities and training provided to employees,
including the log of the sampling data. Activities taken to implement BMPs associated with the
industrial activities, including vehicle maintenance activities, must also be recorded. All
required documentation shall be kept on -site for a period of five years and made available to
the Director or his authorized representative immediately upon request.
2. Minimum Monitoring and Reporting Requirements
Minimum monitoring and reporting requirements are as follows unless otherwise approved in writing
by the Director of the Division of Water Quality:
a. If a facility has multiple discharge locations with substantially identical stormwater discharges
that are required to be sampled, the Permittee may petition the Director for representative
outfall status. If it is established that the stormwater discharges are substantially identical and
the Permittee is granted representative outfall status, then sampling requirements may be
performed at a reduced number of outfalls.
b. Qualitative monitoring shall be performed at all stormwater discharge outfall locations
regardless of representative outfall status. All visual monitoring shall be documented and
records maintained with the Stormwater Pollution Prevention Plan. The initial visual
monitoring event shall be performed simultaneously with the first analytical monitoring event
and documentation of only this initial visual monitoring event shall be submitted along with
the required analytical monitoring submittal.
c. For purposes of the stormwater sampling required in this permit, all samples shall be collected
from a discharge resulting from a representative storm event (See definitions in Part III,

Permit NC0000353
Standard Conditions). Failure to monitor storm events in accordance with the specified
frequency shall constitute a violation of this permit.
• Analytical monitoring for a retention pond designed to contain the 10-year design storm without discharging is
not required. Qualitative monitoring is the only monitoring requirement.
• Analytical and qualitative monitoring are not required from a retention pond designed to contain the 25-year,
24-hour storm without discharging since the pond is considered a non -discharging stormwater control.
d. Samples analyzed in accordance with the terms of this permit shall be submitted on forms
approved by the Director no later than January 31 for the previous year in which sampling was
required to be performed.
e. Analytical results from sampling during the final year of the permit term shall be submitted
with the permit renewal application.
Any other point source discharge to surface waters of the state is prohibited unless it is an
allowable non-stormwater discharge or is covered by another permit, authorization or
approval.
If the storm event monitored and reported in accordance with this permit coincides with a non-
stormwater discharge, the Permittee shall separately monitor and report all parameters as
required under the non-stormwater portion of this permit and provide this information with the
stormwater discharge monitoring report.
3. STORMWATER MONITORING REQUIREMENTS
a. Analytical Monitoring.
During the period beginning on the effective date of the permit and lasting until expiration, the Permittee
is authorized to discharge from outfall 002 - stormwater from process wastewater areas and adjoining
stormwater collection areas. Process wastewater shall not be discharged from outfall 002. Stormwater

A (5). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY)
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to
Ceriodaphnia dubia at an effluent concentration of 11.0%.
The permit holder shall perform at a minimum, quarterly monitoring using test 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 H 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, using the parameter code TGP3B for the
pass/fail results and THP313 for the Chronic Value. Additionally, DWQ Form AT-3 (original) is to be sent to the
following address:
Attention: North Carolina Division of Water Quality
Environmental Sciences Branch
1621 Mail Service Center

Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Branch no later than 30 days
after the end of the reporting period for which the report is made.
Test data shall be complete, accurate, include all supporting chemical/physical measurements and all
concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature.
Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for
disinfection of the waste stream.
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.
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

bt,
Permit Number: NC0000353
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.
A (6). BIOCIDES
The permittee shall obtain authorization form the Division of Water Quality prior to utilizing any new
biocide in cooling water to be discharged. The permittee shall notify the Director in writing, not later
than ninety (90) days prior to instituting use of any additional biocide used in cooling systems, which
may be toxic to aquatic life other than those previously reported to the Division of Water Quality. Such
notification shall include completion of Biocide Worksheet Form 101 and a map locating the discharge
point and receiving stream. No chromium, zinc, or copper shall be added to the treatment system except
as pre -approved additives to biocidal compounds.

Dear Mr. Weaver,

By this correspondence, The Feldspar Corporation request renewal of its wastewater
permit NC 000353. Please find attached the necessary forms required per your letter
dated July 7, 2005.
This permit is believed to be complete as submitted with the exception of the GCMS
testing that will be forwarded as soon as the test results are sent to us.
The water flow balance has variable numbers due to the nature of our water usage in the
processing plants. We have been experiencing a period of declining sales and have not
operated one of our plants for almost a year. We are confident that this business will
return and we will need the capacities that we currently have permitted.
Should you have questions or need further information I can be contacted at 828-765-
8977 or you may also contact Tom Freeman at 828-765-8955.
Sincerely,

Tailings (Sludge) Disposal Plan for The Feldspar Corporation
Spruce Pine Operations: NPDES No. NC0000353
The Feldspar Corporation produces mineral tailings (sludge) at its wastewater facility
located at 530 Altapass road in Spruce Pine, NC. These mineral tailings are disposed of
as follows:
Tailings from the wastewater facility are conveyed outside the building to a staging and
storage area. Tailings are moved to disposal sites by dump bed trucks on Federal, state,
municipal and private roads. Trucks are covered during the transport of this material to
prevent the materials from blowing off the trucks.
Sites are chosen for tailings disposal that will enhance the value of real property by filling
and not present problems through the loss of materials to surface waters by erosion.
Steam buffers are observed (25' min.) and wetlands and seeps are avoided if possible.
Sites are planned and approved by submittal of a soil and erosion control plan through the
NCDENR Land Quality, which explains the land disturbance activities and also gives
details on how stormwater runoff will be handled, how sediment loss will be controlled
and how final reclamation of the site will be performed. Landowner agreements must be
signed to assure future preservation of the sites.
The tailings are also used in reclamation of mine sites and some are sold as fill material.
Ceramic companies who make floor tile and other ceramic products have bought the
tailings for use as a raw material.

WATER QUALITY SECTION
ASHEViLLE REGIONAL OFFICE
Mr. Keith Haynes,
On the 5t' of December 2007 the daily maximum on fluoride pounds to be discharged
was exceeded. The amount discharged on the 5t` was 516 pounds which exceeds the
limit by 68 pounds.
The root cause was operator error in which a miss -communication between the quality
department and the wastewater operator existed. Jerry Prosser addressed this issue with
both parties and this will correct the miss -understanding.
If you have any questions or concerns please contact either myself or Jerry Prosser at
your convenience.
