Paul, do you know if his facility is still discharging?
For some reason, the data for this site was overwritten on SIPS with the
information from NCG500295 (Perdue Farms - Nashville).
I'm not sure how this happened, or what form of dementia made me do '
do need to know if the facility is still. operating. �t'
Any help you can give would be greatly appreciated.
Thanks,

Robert, 1 just corrected a major error on NUCC. The data for NCG500306
(Elk Spinners - Hope Mills) had been overwritten with data from
NCG500295 (Perdue Farms - Nashville). I corrected the facility data,
then queried the FRO via e-mail on the status of the Elk Spinners plant.
Paul Rawls of the FRO called me. The phone number on file for the plant
had been disconnected. He called the Town of Hope Mills and they
confirmed that the site was shut down. According to .the info Paul
recovered, the plant has been shut down since sometime in 1997.
Please delete NCG500306 from NUCC.
Thanks for your help.

We have received a biocide approval request for AG-451 at E1k Spinners, Inc. - Hope Mills
Plant. Data submitted to our office concerning the dosage rate of the product, system volume, average
daily discharge, minimum stream flow, toxicity of the active ingredient(s), and degradation have been
reviewed and evaluated.
Calculations summarized on the accompanying worksheet predict that the use of AG 451 at the
stated dosage rate and discharge conditions will not result in a toxic impact to aquatic life if the discharge
were to reach the receiving stream._ Therefore, the use of_ this_ product as abiocide at Elk Spinners,. Inc. -
HopeMills _Planfis deemed_ acceptable according to current permitting practices. If there are questions
regarding this review please contact me at [phone].

Dear Don:
I have enclosed the Notice Of Intent, Biocide Worksheet-Form 101,
and supporting documentation for Elk Spinners in Fayetteville, N.C.
The existing permit(#NCG500306) does not allow for any biocides to
be discharged from the plant at this time. The enclosed
information should be looked over carefully and signed in the
appropriate place(s).
The Notice of Intent is straight forward with only:a few changes
from the previous form. On Page-1, number 4 requests discharge
volumes in gallons per day.- Number 4B has been reduced from 6800
GPD to 500 GPD for reasons we have previously discussed.-. This
changes the result on Page 2, number 4C from.4.5'gpm to .35 gpm.
Diversey has looked.over this information very carefully.and has
discussed the calculations and other pertinent information with the
Department of Environmental, Health, and Natural. Resources.
Don,:although the State people would not actually tell us if the
biocide(s) would pass after reviewing -the calculations, we felt.
like what. we .have- ,submitted will pass 'their analysis.
Unfortunately and after much painstaking effort, to secure two
biocides for use at your plant, we can only submit, one for
approval. Diversey AG-451 is the biocide that we recommend because
it was the only one that really would pass the "test." We even had
to make some concessions on this product, ie. system 'pH must
operate at 8.8 or higher. We also had the State personnel confirm
the halt -life on this product by linear regression.
The Biocide/Chemical Treatment Worksheet-Form 101 has been filled
out for AG-451 to the best of our, abilities. On page 1 of the
worksheet, you'll notice that the average daily discharge(A.D.D.),
is only.500 gallons.per day. Also on page 1, we recommend that the
dosage rate of 646.88 grams/day be used. Although we won't be
using the product daily., we have -to present it that way.

On page 2, the half-life(H.L.) was calculated with the help of Norm'
Bedwell of DEHNR. In Section III, the LC50 data was reproduced
from supporting data contained with this letter and represents the
values for 5% active. The State environmental personnel that we
talked to recommended that we use the value for Daphnia organisms
because Rainbow trout were not found in this geographical area. On
page 3, we entered the LC50 for Daphnia at the proper value based
on the product's active ingredients.
Don, please review, sign and send the enclosed information to:

Division of Environmental Management
512 North Salisbury Street
Raleigh, North Carolina 27611
Please note that I have enclosed half-life documentation and LC50
documentation on Diversey AG-451 in with this letter. This
information should be forwarded along with the Notice of Intent and
the Biocide Worksheet-Form 101 to DEM.
Thank you very much for allowing me to help you with this
application of Diversey products, my apologies for the delay in
getting you this information.

DBNPA Delivers An Excellent Environmental Profile,
Quick Action, and Broad Compatibility.
This brochure is about DBNPA, a broad-spectrum,
environmentally sound DOW biocide for use in recir-
culating cooling water systems, HVAC systems, once -
through cooling systems. and industrial air washers.
DBNPA (2,2-dibromo-3-nitrilopropionamtde).pro-
vides excellent results in the control of bacteria,
fungi, yeast, and algae. And that can help your
system run better, at higher efficiency, and at
lower cost.
When an effective non -oxidizing biocide is
needed, few if any can match the total performance
package offered by DBNPA. Its fast action gives
results quickly, yet its low persistency minimizes
safety and environmental concerns in discharge.
Here's a look at some of the reasons why
DBNPA may well be the ideal biocide for your
operating requirements.
DBNPA's environmental profile
is ideal for cooling water systems
With tightening discharge standards for both
once -through and recirculating cooling systems,
environmental safety is an increasingly important
factor in the selection of a biocide for these systems.
With a half-life of about 10 hours at neutral pH,
DBNPA offers an ideal degree of persistence for
recirculating cooling systems. It remains active long
enough after addition to effect excellent microbial
control in cooling towers, heat exchangers, and
their related water handling equoment.
But DBNPA also displays an optimum degra-
dation profile; with normal system retention times,
DBNPA will be present in the discharge only at
minimal levels, as Figure 1 shows. That makes it
easy to get highly effective microbial control, yet
operate within the stringent criteria of N.P.D.E.S.'

pH
Figure 1 — Half-life of DBNPA versus
pH (hydrolysis)
and local discharge permit regulations.
Unlike most specialty biocides, DBNPA is
approved by the E.P.A. for use in once -through
cooling systems. That makes it an excellent option
for periodic cleanup of heat exchanger biofouling,
where a concentrated "slug" dose of chlorine might
not do the job at all — or possibly exceed discharge
permit regulations.
Fast kill quickly restores
system efficiency
Rapid microbial proliferation can severely reduce
system efficiency, literally overnight In some cases
What's needed to restore system performance is
more than just effective antimicrobial activity —
it needs to work fast as well.
DBNPA is one of the fastest -acting non -
oxidizing biocides available. At typical use concen-
trations. DBNPA can achieve virtually complete
microbial kill within one to three hours. That's a
feature of enormous value when biofouling cuts
system efficiency to levels that can threaten to shut
down a process associated with the system.
Figure 2 compares DBNPA's rate of kill to
those for other types of non -oxidizing biocides.
As shown in the graph and in Table 1, DBNPA
achieves microbial control at lower concentrations
than the other biocides.

Excellent environmental profile
At recommended use concentrations. DBNPA 1oo.o
presents no serious environmental hazards. With its
rapid degradation profile, DBNPA remains in its
most active form only long enough to kill microbes
in your system. Then breakdown occurs rapidly
enough to leave only trace amounts. if any, in the
discharge water.
DBNPA breaks down via two distinct routes.
including hydroiysis, and photoaegradation, or reac-
tion with nucleophilic agents. Upon degradation,
carbon dioxide is formed. o
As DBNPA breaks down, its decomposition g
products become proaressively less toxic. The end ;,
products of degradation, either oxalic or malonic
acid. and carbon dioxide are conslderea innocuous ,
in the environment at the low, levels encountered.
Excellent compatibility with
most system environments
Ideally, an antimicrobial should have no reactive
effect on a system, other than its ability to control
microorganisms. And DBNPA displays excellent
compatibility with most substances present in
water -based systems.
A key reason for its broad compatibility is
that DBNPA has no ionic charge. So it generally
won't react with charged substances, such as many
of the common scale inhibitors, dispersants, and
corrosion inhibitors.
Additionally, DBNPA is completely soluble
in water. So it stays in solution, where it can work
best to fight microorganisms.
DBNPA also provides excellent results in
co -treatment with chlorine. Neither substance reacts
with, degrades, or inhibits the antimicrobial activity
of the other,
In a combined treatment program in medium-
sized and larger systems, DBNPA helps control a
broader variety of organisms than chlorine treatment
alone. And in smaller systems where overall chemi-
cal treatment programs tend to be less complex,
DBNPA may often be the only biocide you require.

Toxicity hazard to fish
Based on the several degradation path-
ways of DBNPA and its intermediate degradates,
the proper use of DBNPA in industrial water
systems results only in traces of the compound
in discharge water. Chemical and biological
decomposition, and dilution of the effluent
water, result in rapid disappearance of these
traces. Therefore, DBNPA does not present a
serious fish toxicity hazard when used properly.
However, all discharges of DBNPA into lakes,
streams, ponds, or public waters must be in
accordance with aNational PollutantDischarge
Elimination System (NPDES) permit. The cur-
rent data indicate that DBNPA has the potential
for localized fish kill only if a large. amount
of biocide is discharged into a lake or river.

Degradation of DBNPA
in the presence of soil
DBNPA is also degraded by a number
of nucleophiles such as sulfite, bisulfate,
thiosulfate, and sulfide. These compounds
debrominate DBNPA instantaneously to form
cyanoacetamide. Soil, which is a source of
a number of nucleophiles, also accelerates the
degradation of DBNPA. This has been demon-
strated in a number of experiments in which
traces of DBNPA were added to an aqueous
suspension of a number of different types of
soil. Typically, half-lives of 4 hours were
observed at neutral pH, and 15 hours at pH 5.
The disappearance of AG-451/452
solutions in the presence of soil (Table 19)
could be due to absorption, chemical degrada-
tion, microbial degradation, or hydrolysis.
Microbial degradation,of DBNPA has been
demonstrated by the use of tracer techniques.
Rapid reaction in the soil occurs with a
variety of nucleophilic reagents to form
cyanoacetamide, a compound which is bio-
degradable and which can hydrolyze further
to biodegradable materials such as malonic
acid.
Microbial.degradation of DBNPA
In addition to degradation by hydrolysis,
photodegradation, and reaction with nucleo-
philes, DBNPA also degrades to carbon dioxide
under microbial attack. This microbial de-
gradation has been documented under varying
laboratory conditions by tracer techniques.
The fate of the degradates of DBNPA is further
hydrolysis and biodegradability.
Reaction of DBNPA . with sunlight
Decomposition tests show that DBNPA
is degraded by sunlight with the formation of
inorganic bromide ion. In one experiment.
dilute aqueous DBNPA was maintained in a
sealed tube in an outdoor environment for 28
days (pH 4). Less than 1 percent of the DBNPA
remained and more than 95 percent of the
theoretical amount of bromide was formed.
The half-life was thus estimated to be 7 days
under ambient climatic conditions. Exposure
of a dilute solution of DBNPA to a sunlamp
in a laboratory resulted in a half-life of less
than 1 day.
The amount of DBNPA remaining
after exposure to sunlight for 28 days is less
than 1 percent of an original test concentration
of 4000 ppm. The percent of DBNPA
from the same solution after 28 days in dark-
ness is 91 percent. Thus, photolytic degradation
of DBNPA is rapid, and in fact, is signi-
ficantly fast relative to hydrolysis at pH Tess
than 5.

Summary ofdecomposition
reactions
and increasing either or both will increase
the decomposition rate. Hydrolysis is relatively
rapid at neutral to slightly alkaline pH. This
is important because natural waters in most
rivers, especially in industrial areas, are
(typically) slightly -alkaline.
In determining the hydrolysis products of
AG-451/452 the concentrations of DBNPA
' (ca. 12,000-15,000 ppm) were, of
necessity, considerably higher than those of
use conditions (ca. 1 ppm). The pH profile for
the hydrolysis of AG-451/452at 25°C is
shown in Figure 10.
Figure 10 — pH vs. Rate of Hydrolysis of
DBNPA at 25°C
DBNPA possesses two character-
istics that make it unique among nonoxidizing 3.0
biocides: extremely fast antimicrobial action
and rapid degradation to relatively non -toxic 2.0
end products. The dominant degradation path-
way under use conditions involves reaction 1.0
with nucleophilic substances or organic mate-
rial invariably found in water.
Additional degradation reactions include 0
pH dependent hydrolysis, reaction with soil, Y
and breakdown via exposure to ultraviolet o -1.0
radiation.

pathways for DBNPA.

Rate of hydrolysis of DBNPA
The uncatalyzed"hydrolysis of DBNPA -4.0
has been studied in dilute solutions at various
pH levels. The reaction proceeds via decarbox-

Use of Biocides
NPDES# NCG500306
Cumberland County
We have received a second biocide approval request for AG-480 at Elk Spinners, Inc. - Hope
Mills Plant. Data submitted to our office concerning the dosage rate of the product, system volume,
average daily discharge, minimum stream flow, toxicity of the active ingredient(s), and degradation have
been reviewed and evaluated.
We have reviewed this worksheet based on the information provided as well as from data
previously submitted for these active ingredients. We have also utilized an LC50 value of 8.7 mg/1
(whole product) in determining a regulated limitation for Ag-480 since the value originally proposed
(LC50=0.13 mg/1) appears to be for the active ingredient. The facility has also supplied documentation
regarding a half-life value of 20 days for this product. Previous half-life data received by our office for
this active ingredient reports the value to be closer to 2.5 days. We have utilized this value in our
calculations. These revisions did not, however, alter the final analysis portion of the worksheet (Section
IV, page three).
Calculations summarized on the accompanying worksheet predict that the use of AG 480 at the
stated -dosage rate and discharge conditions may result in a toxic impact to aquatic life if the discharge
were to reach the receiving stream. Therefore, the use of this product as a biocide at Elk Spinners, -Inc. -
Hope Mills Plant must be deemed unacceptable according to current permitting practices.
We have alsoreceived an initial request for a corrosion inhibitor CW-4351 at the Hope Mills
Plant. CW-4351 does not contain active ingredients commonly associated with a biocidal product, nor
does it claim to have have biocidal properties. Therefore, approval from our office is not
necessary for its use.

SUBJECT: Enclosed NPDES Permit Application
Dear Mr. Goodrich;
Uniblend Spinners, Inc. recently purchased a subsidiary known as Elk Spinners,
Inc. Elk Spinners has a plant located in Hope Mills, N.C. The plant purchases synthetic
fibers and manufactures synthetic yarns for sale. Plant processes include opening, carding,
drawing, roving, winding, spooling, and spinning. We are submitting the enclosed Permit
application to cover the Plants discharge of water from its cooling tower and its air
washers.
We wish to point out that the 4.5 gallons per minute of discharge in discharge point 1
will very soon be reduced down to .5 gallon per minute. We are replacing the air
compressors with non -water-cooled ones in approximately three (3) weeks.
The Diversey product CW-4351 is being added to the system for the purpose of scale and
corrosion inhibition. This product is being added to the system prior to any discharges.
We are enclosing a check to The N.C. Department of Environment, Health, and Natural
Resources in the amount of $400.00 which we understand is the fee for this type of
NPDES Permit. The enclosed Notice of Intent and accompanying Biocide 101 Form were
prepared with the help of the representative from the Diversey Water Technologies
Company who routinely checks our system. The Material Safety Data Sheets for the
Diversey products used in the systemare also enclosed. Please advise if you need anything
further.

ISOTHIAZOLIN MICROBIOCIDES
GENERAL HANDLING AND SAFETY
Diversey
Precautions used in handling concentrated biocide products are similar to those used for acid
and alkaline materials. The purpose of these precautions is to prevent injury or sensitization
resulting from contact with skin and eyes or inhalation of vapors or mists. Personnel working
with isothiazolin microbiocides must wear protective clothing, including impervious rubber
gloves and safety glasses. Long sleeved shirt and trousers (covering arms, legs, wrists and
ankles) are recommended along with an impervious apron and protective rubber or leather
shoes when splashing is likely.
DANGER! Isothiazolin solutions as supplied are corrosive materials. They may cause irre-
versible skin or eye damage or allergic skin reactions. Do not get in eyes, on -skin or on cloth-
ing. Avoid breathing vapor or mist. Avoid contamination of food. Do nottake internally.
Wash thoroughly after handling and before eating, drinking or smoking.
Automated chemical feed systems are recommended for use with isothiazolin to minimize
potential exposure. Adequate mechanical ventilation should be provided in the area of chemi-
cal feed, particularly when manual feeding practices are in place.
Refer to the Material Safety Data Sheet and label for additional information.
SPILL DECONTAMINATION PROCEDURES
Sodium bisulfite solutions (about 10% active NaHSO3) deactivate isothiazolin microbiocides rapidly.
Personnel cleaning up spills should wear protective clothing consisting of goggles and face shield,
plastic rain jackets and pants, rubber boots or other impervious overshoes, and rubber gloves. All.
protective equipment used during clean up should be thoroughly decontaminated and cleaned before
reuse or placed in drums with the absorbent material, decontaminated and disposed.
The recommended procedure to handle a spill is as follows:
1. Absorb as much of the spilled liquid as possible using an inert absorbent material such
as sand, diatomaceous earth, oil dry or kitty litter.
2. Place the absorbed material and the absorbent into a polyethylene lined-drum:or con-
tainer.
3. Use a 10% sodium bisulfite solution to decontaminate the spill area. A volume ratio of
20/1 decontaminant/active microbicide is recommended.
° Copyright 1994 Diversey Water Technologies Inc. Printed in the U.S.A.
STC-5 Rev. 3194

4. The decontamination solution should be allowed to remain in contact with the spill area
for up to 30 minutes. The actual decontamination reaction takes place in much Tess
time, but the added time will ensure the reaction goes to completion.
5. Once the decontamination reaction has taken place, the area may be flushed to a sani-
tary sewer using excess. water.
6. The absorbed material may now be decontaminated. Place the decontamination solu-
tion in the drums to thoroughlywet the solid material. Let the containers stand open for
48 hours to avoid build up of pressure from the decontamination reaction, then seal and
dispose of according to local, state and federal regulations.
ENVIRONMENTAL IMPACT
Isothiazolin products must be used in accordance with their label application and dosage
guidelines. Treated effluent or waste material may never be discharged to natural waters
without an appropriate NPDES permit and discharge to sanitary sewer is limited to properly
treated system effluent which meets all local sewer code guidelines.

Microbiological control = pH range 7- 9
PURPOSE AND USE
AG-480 is a microbiocide for the control of algae, fungi and bacteria in commercial and
industrial recirculating cooling water systems, air washer systems utilizing mist
eliminators, and paper mill applications.
FEEDING
AG-480 should be fed to the sump or other accessible area of the system where good
circulation and mixing is present. AG-480 should be fed directly from the drum. This.
may be accomplished by using a pump and timer, set to deliver dosage within one
hour.
CONTROL
Prior to initiation of treatment with AG-480, any heavy infestation of microbiological
growth should be mechanically removed from the system. This will avoid the
possibility of severe congestion and fouling attendant to.a massive kill of the growth.
Control of AG-480 application is based on visual observation with treatment repeated
as necessary for proper control.
Use of Mogulab® Total Count Test Kit III will assist in providing proper dosage and
frequency of application information. However, a visual observation of the fill and
deck is recommended.

We have received a biocide approval request for Elk Spinners, Inc. - Hope Mills Plant. Data
submitted to our office concerning the dosage rate of the compound, system volume, average daily
discharge, minimum stream flow, and toxicity of the active ingredient(s), have also been reviewed and
evaluated.
In reviewing the submitted worksheet, we noted missing data and several other errors and
discrepancies:
•Receiving stream was not listed (Section I, page 1)
•"Supplemental Metnls Analysis" (attached) was not completed for the copper contained in the
proposed biocidal compound (Section II, page 1)
•Half-life documentation was not attached as requested (Section II, page 2)
•Error in calculating the receiving stream concentration (Section II, page 2)
•LC50 documentation was not attached as requested (Section III, page 2)
•Worksheet was not properly signed and dated as requested (Section IV, page 3)
We have reviewed this worksheet based on the information provided as well as from data
previously submitted for these active ingredients. We have utilized an LC50 value of 10.01 mg/1 in
determining a regulated limitation for this product. The value originally proposed (.13 mg/1) appears to
be for a 67% (approx.) active ingredient. This revision did not alter the final analysis portion of the
worksheet (Section TV, page three).
Calculations summarized on the accompanying worksheet predict that the use of AG 480 at the
stated dosage rate and discharge conditions may result in a toxic impact to aquatic life in the receiving
stream. Therefore, the use of this product as a biocide at Elk Spinners, Inc. - Hope Mills Plant is
deemed unacceptable. If there are questions regarding this review please contact me at (919) 733-

Supplemental Metals Analysis N�
If copper, zinc, or chromium are present in the proposed biocidal compound, complete this worksheet. A
separate form must be used for each metal and/or metal compound present in the biocide. List the metal,
its chemical formula, molecular weight (MW), formula weight (FW), and the concentration of the metal
compound in the biocide (MCC). Complete a separate form for every metal present in the biocide.

MF = F=
W ( grams/mole) .
.Calculate the fraction of metal in the biocide! compound (BF):
MCC (%)
BF = MF x 100 x (100)
Calculate the concentration of metal in the discharge (M):
M = DC x BF = ug/I x = µg/I
Calculate the instream metal concentration (IMC) at low -flow conditions:
IMC = M x IWC (%) = u.g/1 x % = ua/1
