Consolidated Water Conditioners has submitted on behalf of Shurtape Technologies the biocides
Purobrom and Dow Antimicrobial CT Tablets for approval. Data submitted by the facility
concerning the dosage rates of the biocides, degradation, system volume, average daily discharge, toxicity
of the active ingredient(s) and/or breakdown products, and minimum stream flow have also been reviewed
and evaluated.
Please note:that the LC50 data for the Bluegill sunfish was incorrectly utilized by the facility in the
worksheet. We have used the lower LC50 value of 1.24 mg/L for daphnids with which to calculate the
regulated limitation. This revision, however, did not change the final analysis portion of the worksheet
(part IV, page 3).
Calculations summarized on the accompanying worksheet predict that the use of these products at the
stated dosage rates and discharge conditions will not result in toxic impact to aquatic life in the receiving
stream. Therefore, the use of this product as a biocide at Shurtape Technologies is acceptable.
If there are questions concerning this review please contact me at (919) 73372136.

hello,
the reference to lasting 3 weeks is on page 2
the hand writing on page 1 was some notes i took from the sales rep
if any of it is unclear i can re -scan at a higher resolution
i am working on a location with a small tower about 1000 gal. volume
and a large tower about 2000 gal. voume.
the 7Q10 is 0.20
the ADD is .0014 d(i w t to carry 15 cycles in the towers) -"'•
the lowest LC50 is .1
i was figuring 3 tablets for the 3000 gal volume
each tablet is 200 grams
thank you for you time on your "day off"
i was supposed to be off with my kids today also, but being self employed
has kept me working on this project today.
i got your phone message that the e-mail didn't go through so i tried it
again with a slight modification to your address.

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 D13NPA into lakes,
streams, ponds, or public waters roust be in
accordancewithaNational Pollutant Discharge
Elimination System (NPDES) permit. The cur-
rent data indicate thatDBNPA has the potential
for localized fish kill only if a large amount
of biocide is discharged into a lake or river.
Far further guidance, contact your local BPA
regional office.

Recirculating water
cooling towers
Recirculating water systems am com-
monly contaminated with fungal and bacterial
organisms, and occasionally with algae. In
addition, their spores and reproductive cells
are continuously present in the air, so the likc-
lihood of repeated innoculation is extremely
high from a biological standpoint.
With their extremely fast killing action,
DOW Antimicrobials 7287 and 9536 effectively
control entering microorganisms before they -
can create problems. Because most microorgan-
isms are killed verysoon after exposure, there
usually isn't time for daughter generations to
develop. Fast kill means first generation kill,
which goes a long way toward preventing adap-
tation to the biocide or defense through secre-
tion of biofilm.
Kill rate outpaces degradation rate
DOW DBNPA typically yields a 99.999
percent kill before it degrades sufficiently to
lose effectiveness. Figure 1 shows the degrada-
tion profile of DOW DBNPA for various tem-
perature and pH combinations.
At neutral pH and normal system oper-
ating temperatures, DOW DBNPA exhibits a
half-life of about nine hours. As pH increases,
the rate of degradation of DOW DBNPA in-
creases, but virtually complete microbial kill
is achieved well before significant degradation
occurs. As shown in Figure 2. DOW DBNPA
easily achieves 99.999% kill in under three
hours even in alkaline systems.

chlorine treatment
DOW Antimicrobial 7287 and DOW
Antimicrobial 8536 provide excellent results
in co -treatment programs with chlorine.
Neither substance reacts with, degrades, or
inhibits the antimicrobial acdvity of the other.
In combined treatment programs in
larger systems, DOW DBNPA antimicrobials
help control a broader variety of microorgan-
isms than chlorine treatment alone.

RE: Half Life.ofHalogen from BromiCideo
CC: Leisa Corbett, Michelle Harrison
Number of pages including cover sheet: 1
Dear Mr. Spencer:
Going back into archives of work that was done in the late 1980's we were able to find some work
that was done on half-life of halogen from BCDMH in natural outdoor conditions. Please note that
this information is not from simulated UV light, it is actual use information collected from BCDMH
being used in an outdoor environment. T of halogen from BCDMH in an actual outdoor
environment ranges from'
I hope this helps you with your permitting question. Please let me know if there is anything else I
can do to help. Thank you for your support of our products.

BromiCide
PRODUCT INFORMATION
June 13, 1997
Granules
BromiCide GRANULES ARE THE
INTERMEDIATE FORM OF BromiCide'. Thev
are the product of choice where you want to quickly attain a
halogen residulal, but desire the simplicity of control of a
Brominator.
• SAFER HANDLING. Because of its solid form.
BromiCide is easier to handle than most common gas and liquid
oxidizing biocides, thereby reducing the likely risk and impact of
environmental exposure.
• ENHANCED ENVIRONMENTAL
ACCEPTABILITY. BromiCidego decays rapidly allowing
for safe discharge into most waste water systems.
DESCRIPTION AND USE
BromiCide Granules (1-bromo-3-chloro-5,5-dimethylhvdantoin) offers
a safer, more effective altemative to chlorine based oxidizing biocides
and non -oxidizing biocides for microbiological control in industrial
cooling waters. When dissolved in water, BromiCide' Granules generate
hypobromous acid.
BromiCide° Granules are registered with the United States
Environmental Protection Agency for use in once -through and
recirculating cooling waters, heat exchange water systems, air washers
equipped with mist eliminators, industrial water scrubbers, influent
water systems, brewery pasteurizers, cooling ponds, and wastewater
treatment systems.
TREATMENT AND DOSING REQUIREMENTS
BromiCide' Granules effectively controls bacterial, algal, and fungal
slimes that can cause costly reductions in heat transfer efficiencv.
BromiCide' Granules can either be dosed on a continuous or
intermittent shock basis using a specially engineered dosing system
For noticeable fouling, add 0.2 - 0.5 ppm as Cl, for continuous dosing,
or 1 - 2 ppm as Cl_ for intermittent shock dosing. Typically, in well
managed systems, successful control has been demonstrated with
dosages in the range of 0.1 - 0.3 ppm total halogen as Cl_. For more
information, contact Great Lakes Water Treatment technical support at
the above number.
TYPICAL PROPERTIES
BromiCide Granules are white to off-white in color and have a faint
halogen odor.

STORAGE AND HANDLING PRECAUTIONS
Keep BromiCide Granules dry in a tightly closed container. Avoid
contamination with moisture, chemicals or any other foreign materials due to risk
of explosion, fire and release of hazardous gases. Store in a cool, dry, well -
ventilated area away From heat sunlight, open flames and organic materials such
as greases, oils, and solvents.
BromiCide Granules are corrosive in solution, and may be fatal if swallowed.
Inhalation of dust may cause irritation of the nose and throat, and irritation to
skin. Always wear a dust mask approved by the appropriate national authority,
impact -resistant safety goggles or safety glasses, and a full -face plastic shield
with forehead protection. To avoid contact with skin, wear rubber or plastic
gloves, long pants, and long shirt sleeves. Always tuck gloves under shirt
sleeves and leave pant legs outside of boots. Wash contaminated clothing and
equipment before reuse.
SAFETY PRECAUTIONS
Do not leave wet BromiCide° exposed to air inside a Brominator teed system.
,after adding BromiCide° but before replacing the top closure, refill the tank with
water. Failure to do so may allow for product decomposition leading to pressure
build-up in the feeder. High pressures may lead to rupture of the feeder causing
serious bodily injury or property damage by explosion, fire or release of
hazardous gases.
Contact of BromiCide Granules with organic materials such as alcohols,
aldehydes, and ketones, or strong reducing agents may cause a chemical reaction
leading to a pressure build-up in the feeder. High pressure may lead to'rupture
of the feeder causing serious bodily injury or property damage.
Before handling BromiCide Granules, all persons must be thoroughly aware of
the hazardous properties and have reviewed a ;Material Safety Data Sheet
(1vISDS). A NISDS may be obtained from Great Lakes Water Treatment.
PACKAGING INFORMATION
BromiCide Granules are available in 25 and 50 pound pails, and 500 pound
bulk bags.

hazardous.
SYSTEMIC (OTHER TARGET ORGAN) EFFECTS: Excessive exposure may
increase the blood and tissue levels of bromine. observa-
tions in animals include kidney effects following repeated
ingestion, but no evidence of systemic. toxicity following
repeated dermal exposure at maximum attainable doses (data
on active ingredient). Ingestion of extremely large amounts
of stearic acid may lower blood clotting time.
4. FIRST AID
EYE: Irrigate with flowing water immediately and continuously for
15 minutes. Consult medical personnel.
SKIN: Wash off in flowing water or shower.
INGESTION: If swallowed, induce vomiting immediately as directed
by medical personnel. Never give anything by mouth to an un-
conscious person." Consult medical personnel. Seek medical
attention immediately.
INHALATION: Remove to fresh air if effects occur. Consult a
physician.
NOTE TO PHYSICIAN: If burn is present, treat as any thermal burn, -
after decontamination. No specific antidote. Supportive care.

I-ERROMO--3-OHLORO-5, 5-DIt+ETHYLMANTOIN
(BROMICIDEO)
TY DATA
Background: l-Ero-3-chloro-5, 5-dimethylhydantoin (ACME) is a
biocide. When dissolved in water, scmi hydrolyzes immediately to
hypobromous acid, hypochlorous acid (the active biocides), and 5,5-
dimethylhydantoin (). Toxicity data are available for either
SCDMH or DMH, but not necessarily for both. Summaries of toxicity
data which are from the Federal EPA registration files are so
indicated.
I. Microbial Mute enici.tY: 2=NN wag tested for potential
mutagenic effects using a series of in nitro micrQbial assays
employing Salmonella and SacchAZWRyces indicator organisms in the
absence and presence of liver microsomal enzyme preparations ,from
Arochlor (39) induced rats. The results of the tests were all
negative. 3CDMH teas not mutagenic under the conditions tested.
MO was tested for potential mutagenic effects using a series of in
vitro microbial assays employing Salmonella and Saccharomyces
indicator organisms in the absence and presence of liver microsomal
enzyme preparations from Arochlor (S9) induced rats: The results of
the tests were all negative. DMH was not mutagenic under the
confli.tions tested.
2. Mam=lian Cell Mutageni,bity: MM wa.s eValuated in rats for the
potential to induce zhromosome aberrations in bone marrow cells when
administered by oral gavage to male and female rats, Dose levels of
200, 660 or 2000 mg/kg resulted in no statistically significant
increases in the fro uency of chromosomal aberrations when comparecl
to control values.
DME was evaluated fo the potential to induce gene mutations in
cultured L517F,Y mousa lymphoma cells in the absence and presence of a
metabolic activation system. Under tha test conditions, DMH, at
concentrations up to and including 1000 }gg/mL, did not cause an
increase in forward mutations in L5178Y mouse ly=homa cells.
DMA at concentratjQn3 up to and including 1000 µg/ML was tested for
the potential to tra sform cultured C8H 10T 1/2 cells in the absence,
and presence of a me abolic activation system. In the absence of a
metabolic activation no dose related cytotoxicity and no Type ITT
foci (transformed oe 15) were produced. In the presence of a
metabolic activation no dose related cytotoxicity resulted, but one
Type Iz2 focus was p oduced at each concentration of 10, 30 and 300

BCDMH was administered as a sir4gle oral dose
on to groups of five male and five female -rats at
370, 650, 741 and 845 mg/kg. The combined oral
ulated to be 578 mg/kg.
Lty of BC,DM8 was determined to be greater than

ombined..LCsa of BCDMH was calculated to be 0.168
In one study the ac to oral LDgo for DM in rats was reported as being
>4000 mq/kg.
MM was administered as a single oral dose via gastric intubation to
groups Qf five male and five rats. on the day of dosing two .females
were observed to be slightly to moderately lethargic with slight
lacrimation; they were normal for the remaining 14 days. The acuto
oral LDso was calculated to be >5000 mg/kg.
The acute dermal to ia�ty of Db'i was determined to be greater than 3
g/kg for both ma-,e and female rabbits. No signs of systemic toxicity
were.observed. 5,5-Dimethy1hydantoiri is practically non -toxic by the
dermal route of'expasure.
4. Irritation (Skin and Eye): The primary skin irritation index
for SCmm was calculated to be 6.1 according to the method. of Dtaize.
Eschar and necrosis of the skin were observed through day 7. On day
14, the irritation score was zero and eschar and necrosis were no
longer observed. BCDMH was considered corrosive to the skin.
Prolonged or repeated skin contact with solid BcDj4n resulted in minor
reddening of the skin and superficial necrosis with the development
Of excessive exfoliation. Contact with dilute solutions of 0.1$ or
less (1000 ppm or less) was not irritating to the skin (Federal EPA
registration tiles).
Eye contact with the powdered ErDMH resulted :Ln persistent severe
conjunctival irritation and slow development.of corneal damage in
rabbits. Washing the eyes promptly (within 30 seconds) resulted in a
significant reduc-tiou of adverse effects. Dilute soiutions of 0.1-t
(1000 ppm) or less ware essentially non -irritating to the eyes
(Federal EPA registr tion files).
DMH was tested for S in irritation. Slight irritation and edema were
observed at 24 hours in the majority of the rabbits for both intact

and abraded sites. IAt 72 hours, two abraded sites showed slight
erythema; there wer no other reactions. The primary jRjj% irritation
index was calculate to be 0.8 according to the method of Draize.
5,5-Dimethylhydanto�n is classified as minimally irritating to the
skin.
tye contact with po dered DbIIi resulted in slight to moderate erythema
and slight to marked ahemosis and discharge at the 17hour reading in
all rinsed and unri sod. eyes. All irritations had completely
subsided at the 7 d y reading. The primary irritation index,

DbM was evaluated f c r toxicity in a 13-week subchronic toxicity study
in beagle dogs. Dosages of 250, 500 ard.1000 mg/kg/day were
administered by capsule to groups of six males and six females.
There were no adver a effects on survival rate, clinical condition of
the animals, body Weight gain, food consumption data, clinical
pathologic paramete s or organ weight data. No macroscopic or
microscopic examina ions of selected tissues revealed lesions that
could be attributed to the test material. The No -observable -Effect -
Level (NOEL) was co sidered to be 1000 mg/kg/day in this study.
S. DevelopmentalToxicity: DMH was evaluated for potential
maternal and/or developmental toxicity in a range -finding study in
rabbits. DMH Suspended in 1$ aqueous methyl=cellulose was
administered orally to groups of seven inseminated does as a single
daily dose from day 6 through 16 of gestation. Dose levels were 0,
250, 500, 1000, 200C and 2500 mg/kg/day. No compound related deaths
or abortions occurred. Clinical signs (decreased defecation and
white to brownish c ystalline-like material in the feces) were
observed in the 250 mg/kg/day group. Body weight loss and
reductions in food consumption were dose -related in the 1000 mg/kg
and above groups. lo treatment -related gross necropsy findings were
observed at any dose level. Post -implantation losses were increased
and live litter size was decreased at dose levels of 2000 and 2500
mg/kg/day. A sgveri raduction. in mean fetal body weight was observed
in the 2500 mg/kg/d y group. EXternal fetal malformations, primarily
involving defects of the digits (adectyly and brachydactyly),.were
noted at dose levels of 1000, 2000 and 2500 mg/kg/day in 1, 7 and 10
fetuses, respectively- No external fetal variations were observed in
any close group. The (NOAEL) was
considered to be 500 mg/kg/day for maternal and developmental
toxicity.
DM was evaluated i rabbits for potential maternal and developmental
toxicity. Dose le v is of 0, 100, 500 and 100.0 mg/kg/day in 11%
aqueous methyl-celltLlose were administered to groups of 20
inseminated ra-bbitg as a single dose on days 6 through 16 of
gestation. A dose evel of 1000 mg/kg/day produced moderate maternal
toxicity that was a hibited by reductions in body weight gain and
food consumption, p imarily d"Tr_rich the initial six days of compound
administration. Potential developmental. toxini,'ty Was expressed by an
increase of one specific skeletal variant at dose levels of 500 and
1000 mg/kg/day and digital defects (forepaw digit #1) at a dose level
of 1000 mg/kd/day. The dose level of 500 mg/kg/day wag considered
the No -Observable -A verse-Effect-Level(NOAEL) for maternal tbxiQc ty
and a dose level of 100 mg/kg/day was considered the NOAEL for fetal
developmental toxicity.

3.9. Aquatie Uptake Depuration and Bioconcentration: A dynamic 42-
day study evaluated the bioconcentration of 14C-DMH using 511aegz].l
sunfish, Lepomis ma rochlrus. A.flaw-through proportional diluter
system was used to maintain a measured water concentration of 4.4
(± 0.33) ppm 14C-5,5 dimethylhydantoin for a 28 day exposure period.
Radio -analysis of fillet, whole fish and visceral portions were
performed throughout the exposure period. Daily bioconcentraton
factors were all less than the minimum quantifiable limits (OMD) for
viscera, fillet and whole fish throughout the exposure period.
Uptake tissue concelLtrations of 14C-DMH were less than the minimum
quantifiable limits for fillet, whole fish and viscera. Therefore,
5,5-DMH basically did not bioconcentrate after 28 days of exposure.
To measure the elim nation of laC-DMH, the test, fish were placed in
clean water for 14 ays. Radio -analysis throughout the depuration
period indicated less than minimum quantifiable limits for fillet,
whole fish and .viscera. .since neither an uptake rate constant (K1)
nor a depuration rate constant (K2) could be calculated or observed, a
non -linear two compartment kinetic modeling program (HIOTAAC) could
not be used for the analysis of the uptake/depuration data.
17. 96-Hour Stati Aquatic Toxicity: [Test protocols for fish and
crustacean bioassay were based on ``Registration of Pesticides in the
United States" in F deral Register Vol 43, No. 132, July 10, 1378.
Toxicity tests and general guidelines for the American oyster were
based on guidelines in "Methods for Acute Toxicity Tests with Fish,
Macroinvertebrates and Amphibians" (EPA-600/3-75-O09, April, 1975),

23. Photolysis: The photolysis study was conducted with radio -
labeled Dt+m in water at pH 7. The half-life for DMH in the
sensitized exposed system was 2295 days. For the non -sensitized
system, the half-life was 2100 days. The half-lives calculated
represent the degradation rate based an little or no degradation.
24. Biodegradati.c ! The hi.odegradatjon of Dm, the dehalogenated
by-product of 1-bro o-3-chloro-5,5-dimethylhydantoin, was
investigated using ierated mixed cultures of microorganisms found in
activated sludge. Iludge was acclimated to 25 ppm unlabeled DMH over
a 2-week period. R dio-labeled DMH was added and levels of DMH and
radioactivity were monitoxed. Within 24 hours the level of DMH in
the incubation mixt re (measured by HPLC) decreased from about 20 ppm
to
an average of 5 ppm, a 75% lass. in tht same period, however,
radioactivity in the mixture showed only a 19% loss, this is
explained by the release of metabolites into solution and subsequent
absorption
by the particulate Matter. After 3 days, DMH concentration in the
mixture was <1ppm, and radioactivity had decreased to 491 of its
original level, showing that metabolites were ultimately leaving the
system as carbon di x1de. By 19 days, 94% of the radioactivity had
been recovered as c rbcn dioxide. Only tract amounts of
radioactivity were ound to be volatile other than oarbo7l dioxide,
and these
appeared to be due to aerosols from the incubation mixture. when the
results were correG ed for known leakage of carbon dioxide in the
apparatus, a carbon balance was maintained. Under the test
conditions, DMH deg cedes rapidly without obvious toxic effects upon
the organisms.
25. Avian Acute 4 al LDso (Bobwhite quail): Sixty 27-week-old
Bobwhite quail -Were administered a single oral dose of DMH at dose

parent compound. N degradation products were observed in the
extracts. The persstence of radio -labeled DMH on soil under aerobic
conditions precludeithe estimation of a half-life.
31. Li�ta(Nhing: Rac io-labeled DMS was used in a laboratory leaching
study. The radio -labeled DMH reGovererd from the replicate columns of
four types of soil I sandy loam, silt loam, loam and clay loam) were
determined to be 90 1�1, 104.2*, 100.7%, and 95.2t of the total
applied DMH, respectively.
32. Adsarption/De orption: Aqueous solutions of radio -labeled DMB
were equilibrated with four soil types. Analysis demonstrated that
90 to 951 of the radio -labeled DMH was accounted for in the.aqueaus
phase. No significant adsorption of DMH onto any of the soil types
was observed. The soil adsorption coefficient, ECd and Ka, are as
follows:
