Shurtape Technologies,. Inc. has submitted Advantage Plus 6445 and Valugard 250D for
approval. Materials submitted by the facility have been reviewed and evaluated. The proposed
compounds do not appear to be, nor are they claiming to be biocidal compounds and would thus not
require individual review and approval using the standard biocide review process. As with the use of
many additives, effluent pH may be affected, and should be monitored. Following current permitting
practices, the use of these compounds should be allowable.
We are continuing to work with the facility and chemical supplier on Drewsperse 751. The
facility is in the process of submitting data regarding the specific active ingredient. We will forward this
information to you once we have completed our review.
The facility has also submitted additional data for Biosperse 250 and has requested that we
again consider this product for use as a biocide. Data submitted by the facility. concerning the dosage rate
of the compound, degradation, system volume, average daily discharge, toxicity of the active
ingredient(s) and/or breakdown products, and minimum stream flow has been reviewed and evaluated.
Note that, due to the geographic location of the facility, the regulated limitation was calculated using the
more appropriate channel catfish LC50 value of 6.7 mg/l (attached). This modification did not affect the
final analysis portion of the worksheet (page 3, part IV). Calculations summarized on the accompanying
worksheet predict the use of Biosperse 250 at the stated dosage rate 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, Inc. is deemed acceptable.
If there are questions regarding this review please contact me at [phone].

Water may be used to keep fire -exposed containers cool until fire is out. Wear
a self-contained breathing apparatus with a full facepiece operated in the
positive pressure demand mode with appropriate turn -out gear and chemical
resistant personal protective equipment. Refer to the personal protective
equipment'section of this MSDS. No special precautions necessary when fighting
fires involving this product.

6. ACCIDENTAL RELEASE MEASURES
Small Spill f
Absorb liquid on vermiculite, floor absorbent or other absorbent maw _or
ia1.
Large Spill _
Persons not wearing protective equipment should be excluded from area or spill
until clean-up has been completed. Stop spill at source. Dike to prevent
spreading. Absorb with inert material. The absorbent(and surface soil to a
depth sufficient to remove all microbiocide) is then shoveled into a pail or
drum and treated with enough decontaminant solution to wet the solid
thoroughly. Let these containers stand open for 48 hours to avoid the buildup
of pressure, then seal and dispose of by burying as landfill. The
decontaminated area is washed with additional decontaminant solution and then
flushed into a chemical or municipal sewer. Do nct'discftarge spills and
cleaning runoffs into open bodies of water. Remove.clothing promptly; launder
before reuse. Wash skin with soap and water.. Decontaminant solution: sodium
bisulfite solutions (about 11% solids content) decompose Biosperse 250 rapidly.
Laboratory tests indicate that the microbiocide is almost completely--
deactivated within 30 minutes when treated with at least 4 equivalents of
decontaminating solution. A volume ratio of20/1 decontaminant/active
microbiocide is recommended. The following solutions are acceptable
decontaminants: Ingredient: sodium metabisulfite (weight = 1 pound) +
water(weight = 8 pounds). Total 9 pounds.. Solids content = 11.1%. pH = 4.2.
Ingredient: sodium bisulfite (weight 1 pound + water (weight 8.3 pounds).
Total 9.3 pounds. Solids content = 10.7%. pH = 4.2. Ingredient: sodium
sulfite (weight = 1 pound) + water (weight = 7 pounds) + hydrochloric acid(37%)
(weight = 0.67 pounds). Total 8.67 pounds. Solids content = 9,.5%. pH =
5-5.5. Note: Decontaminant solution must have ph on the acid side; since it
is much less effective when alkaline. In converting sodium sulfite to the
bisulfite, dissolve the salt in water and slowly add the acid with good
agitation to prevent liberation of sulfur dioxide caused by local excess of
acid. Keep containers of decontaminant solution closed or covered to reduce
accumulation of sulfur dioxide in the workplace (threshold limit value(ACGIH) 2
ppm). The solutions should be made fresh as needed. Personnel making up or
handling decontaminant solutions should.wear goggles or face shield and rubber
gloves.

Handling
Containers of this material may be hazardous when emptied. Since emptied
containers retain product residues (vapor, liquid, and/or solid), all hazard
precautions given in the data sheet must be observed.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Eve Protection
Chemical splash goggles and face shield (8" min.) in compliance with OSHA
regulations are advised; however, OSHA regulations also permit other type
safety glasses. (Consult your industrial hygienist.)
Skin Protection
Wear resistant gloves such as:, -neoprene, ni'trile rubber, To prevent skin
contact, wear impervious clothing and boots., Other protective equipment:
eyewash station, emergency shower..
Respiratory Protections
If overexposure has been determined or documented, a NIOSH/MSHA jointly
approved air supplied respirator is advised in absence of proper environmental
control. OSHA regulations also permit other NIOSH/MSHA respirators under
specified conditions. (See your safety equipment supplier.) Engineering or
administrative controls should be implemented to reduce exposure.
Engineering Controls
Provide sufficient mechanical (general and/or local exhaust) ventilation to
maintain exposurebelow level of pverexposure (from known, suspected or
apparent adverse effects).

General
8105FUSE 261T micraolocide is a broad-spectrum
antimicrobial product designed specifically for control of
bacterial, fungal and algal slimes in industrial recirculating
cooling water.systerns. BIOSPBSE 261T microbiocide is a
solid microbiocide which liberates hypobromous acid.
hypochlorous acid and S.S-dimethylhydantoin when
dissolved in water. This envuonmental profile is designed to
address common questions about the impact of BIOSPERsc

Degradation Data
The non -toxic dehalostenated by-product of BIOSPERSIc 261T
microbiocide. 5a-dirnEtttylhydantoin, is biodegradable as
determined by carbon-14 radiolabeling of sewage sludge,
After 19 days, 94 percmt of the carbon-14 had been recovered
aR carbon 'dkudde. Under the beat cunditium, the
dehalogenated bwpt+aduct of BIOSPERSE 261T microbiocide
degraded rapidly with no obvious toxic effects upon the test
organisms.
HYpobromous and hypochlomm acid can degrade by
reacting with of WX& to form halogenated by-products.
These by-products can be carcinogenic and acutely toxic to
aquatic organic & Hypobromous acid differs from
hypochlorous acid in that brominated organics degrade
much quicker than chlorinated organics. For example,
bromofarm has a i ali-life of 15 days compared with 50 days
for chloroform. A seeded; anaerobic culture with 160 ppb of
brominated trihaiomethane degraded to less than 0.1 ppb in
less than two wekc , When 157 ppb of chlorinated
hihalomethane was nut using the same method, 117 ppb .
remained after two weeks. Bromoberame degrades in
1 /100 of the time of ddarobenz me.
DetoXilleation
If a spill of the tablets occurs, dry tablets can simply .be
collected and used. If a solution of BIOSPBSE 261T
microbiocide is spilled, the hypohromous and hypochlorous
acid can be deta riiied by carefully adding a.dilute solution
of a reducing agent such as sodium metabisulfite or sodium
bisulfite.
