5. PROCESS AND RELEASE INFORMATION
5.1. Distribution, Transport and Storage
PORT OF ENTRY
Melbourne, Victoria.
IDENTITY OF MANUFACTURER/RECIPIENTS
One user in Melbourne.
TRANSPORTATION AND PACKAGING
Transportation is expected to be by road and rail. The notified chemical is to be imported neat in 50 or
216 kg fixed-head steel drums, blended into lubricants and hydraulic fluids and filled into small
(< 50 L) plastic containers and 200 L plasticor metal drums.
5.2. Operation Description
Blending of the notified chemical into lubricants or hydraulic fluids is accomplished either by
decanting under local exhaust ventilation into a blending vessel or pumping via a closed system. If
decanting is used, the drum bung is removed and replaced by a control valve prior to raising the drum
by a foot-powered drum tilter over the blending vessel manhole. Each emptied drum is rinsed with
base fluid and the fluid added to the blending vessel. After the addition of other ingredients, blending
takes place with the removal of small samples for QC checking. Final products are then filled into
packaging via a closed system under local exhaust ventilation.
Use in greases or transmission oil is not envisaged. The notified chemical is expected to be used in
turbine and circulating oils, compressor oils, hydraulic fluids, gear oils and possibly automotive gear
oils and marine lubricants at a concentration between 0.1% and 0.5%. The hydraulic fluids, which
will comprise approximately 40% of all applications, may be used in the steel industry, mining,
agricultural, automotive and manufacturing industries. Typically, the oils and hydraulic fluids will
have a long service life and may be filled to machinery via automatic systems, particularly when the
machinery is first manufactured.
5.3. Occupational exposure
Number and Category of Workers
Category of Worker Number Exposure Duration Exposure Frequency
Blending operator 1 < 1 hour/day 25 days/year
QC Technician 1 < 1 hour/day 25 days/year
OEM Applicator 20 < 1 hour/day 50 days/year
Maintenance operator 50 < 1 hour/day 50 days/year
Exposure Details
Inhalation exposure is not expected given the low vapour pressure of the notified chemical. Dermal or
to a lesser extent ocular exposure appears to be controlled during decanting by the use of a control
valve and pumping via a closed system. Some minor spillage may be expected and worker exposure is
controlled by the use of long PVC or nitrile gloves, eye protection and overalls. For the QC technician
the possibility of exposure during removal of small samples is possible and is controlled by use of the
same personal protective equipment.
The greatest potential for exposure exists for machine maintenance workers as residues will remain in
lines and associated devices. However, breakdowns should be relatively infrequent and maintenance
workers will be wearing gloves to prevent dermal exposure.
Workers involved in filling oils or hydraulic fluids to machinery are exposed to the notified chemical at
a maximum concentration of 0.5%. Typically gear oils or hydraulic fluids would be added when the
machinery is manufactured and only small amounts would be added over its life. Complete change of
oil or fluid would be infrequent.

5.4. Release
RELEASE OF CHEMICAL AT SITE
The notifier does not anticipate release of the chemical during handling or transport from the port to
the customer site except in the event of an accident. Such spills are not expected given the sturdiness
of the fixed-head steel drums.
Some release of the notified chemical at the blending site is possible as a result of incidental spills or
leaks and during blending and machine maintenance. In general, however, fluid remaining in pumping
lines and equipment is usually purged and recycled in the next batch of product. The notifier estimates
that waste generated during formulation will not be more than 0.2 L per tonne of the imported
substance per year. Given a maximum import volume of 8 tonnes, this equates to about 1.6 L of
notified substance generated as waste during formulation.
In the event of accidental release, the MSDS recommends the substance be taken up with absorbent,
inert material and the material placed in sealable containers for disposal in accordance with State
regulations by High Temperature Incineration.
The notifier has indicated that the empty import containers will be rinsed with base fluid and the rinsed
material added back to the blending vessel so that there will be virtually no notified substance left in
the drums. The drums are then sent to accredited drum reconditioners for recycling.
RELEASE OF CHEMICAL FROM USE
Release of the notified chemical contained in the lubricant and hydraulic fluid at end use could occur
in several ways, including through leakages from mobile machinery during operation, through spills
during oil changes, and from improper disposal of used oils following machinery oil changes.
However, it is difficult to estimate the amount of oil released to the environment through these routes.
The amount of lubricant oil resurfacing as used oil will depend on the type of application, with some
applications resulting in all of the used oil being generated as waste, and others resulting in all the oil
being burned or lost through leakage (Macpherson, 1997). Because the lubricant will be housed in
sealed units which are changed at a frequency of 3 to 5 years, the notifier expects release through
leakages from mobile machinery will be insignificant.
The fate of used oils in Australia has been the subject of a number of surveys. Australian Institute of
Petroleum surveys (AIP, 1995; 1998) indicated that at least 60% of all used oils generated are
collected for recycling to be resold mainly as fuel oil. The fate of the remaining 40% of used oil could
include a substantial portion being reused especially in the mining, agricultural and transport sectors.
The AIP 1998 report indicated no evidence that bulk used oil was being dumped, but admitted there
was some uncertainty as to the fate of 40% of used oil generated, but not collected for recycling.
Release through improper disposal is expected to be minimal for lubricant sold to the industrial
market, where most used oils are disposed of by recycling or refining. Given the industrial
applications, the notifier expects that almost 100% of fluids containing the notified chemical will be
sent for recycling.
5.5. Disposal
The MSDS recommends the notified chemical be disposed of by high temperature incineration and
according to State Regulations.
5.6. Public exposure
There is potential for public exposure to the notified chemical in an accidental spillage during
transportation. In the event of spillage, the spills should be soaked up with inert material (e.g. sand,
silica gel, acid binder, universal binder, sawdust), and collected into tightly sealed and properly labelled
containers for incineration or landfill. The spills should not be flushed into surface water, sanitary
sewer or ground water system. In the formulation plant, washing from purging of blending and
packaging equipment with a base fluid will be recycled into the next batch of the product, and no more
than 0.2 L per tonne of the notified chemical per year will be produced as waste for disposal. Empty
drums will be rinsed with base fluid and the rinses pass to the blending process, and the rinsed drums
are send to an accredited drum reconditioner. Used oils will be recycled and none should be disposed

of to sewer or landfill. In case of the oil disposed of unlawfully to landfill, the leachability to ground
water in landfill would be expected to be negligible as the hydrophobic nature of the notified substance
would indicate strong absorption to soils.
The notified substance will be incorporated into lubricating oils and hydraulic fluids at low
concentrations (0.1 - 0.5%). The end use lubricants will be predominantly gear oils used industrially
and the public exposure should be low.

Remarks Following a preliminary test using a simple flask method, excess amounts (25 mg)
of test substance were added to 25 mL water, and the 6 test flasks shaken for 24,
48, and 72 hours, respectively. The flasks were equilibrated for 24 hours and the
supernatant solution was filtered and centrifuged prior to HPLC analyses to
quantify the concentrations of test substance dissolved in solution. The
concentrations in the 6 replicate samples determined after 24, 48, and 72 hours
differed by less than 30%, indicating the test was valid. The test results indicate the
notified chemical is slightly soluble in water.

Remarks Preliminary hydrolysis testing was carried out at pH 4, 7, and 9 and at a
temperature of 50癈 over a 5-day test period. The test substance was found to be
stable at pH 7 and 9, and hence no further testing was conducted. At pH 4, 17% of
the test material was hydrolysed after 5 day, and so further testing was performed
at temperatures of 25, 50, 70, 80癈. These results indicate the notified chemical
only slightly hydrolyses at pH < 4.

METHOD OECD TG 117.
EC Directive 92/69/EEC A.8 Partition Coefficient.
Remarks To prepare the stock solution, an amount of test material was dissolved in 20 mL
acetonitrile and the solution diluted to the required concentration. The HPLC
retention times of the test substance (3 reps) were compared against those of the 6
reference substances (6 reps each). The log Pow was calculated using a regression
curve. The results indicate the notified chemical has a strong affinity to lipids.
TEST FACILITY RCC (2000e).
log Koc = >3.14.
Adsorption/Desorption
METHOD OECD TG 106.
Remarks The adsorption coefficient was determined using regression equations based on the
water solubility and the molecular weight of the notified chemical. These were as
follows:
Regression I: log Koc = -0.55log S + 3.64 (S = water solubility in mg/L)
Regression II: log Koc = -0.54log S + 0.44 (S in mole fraction)
Regression III: log Koc = -0.557log S + 4.277 (S in mmoles/L)
An estimation was also performed based on the partition coefficient and using the
regression equation: log Koc = 0.544logPow + 1.377. The results indicate the
notified chemical has low mobility in soils.

pKa = 4.3
Dissociation Constant
METHOD OECD TG 112.
Remarks The dissociation constant was estimated using linear free energy relationships
according to the Hammett and Taft equations derived for aromatic and aliphatic
systems, respectively. The results indicate the notified chemical will be dissociated
in an aqueous environment in the pH range 5 ?8. The calculation was based on
dissociable functional groups. The notified chemical has one site which can be
protonated. The acid pKa based on Taft is 4.3.

Clinical Observations
No remarkable clinical signs or effects on food consumption or body weight.
Laboratory Findings ?Clinical Chemistry, Haematology, Urinalysis
Clinical Chemistry
Elevated triglyceride and phospholipid levels were noted in high dose animals of both sexes and elevated
cholesterol levels in high dose females. These changes were considered to be an adaptive response and were
reversed during the recovery period. All changes were within the 95% confidence limits of the historical control
data.
Higher albumin levels and albumin/globulin ratios were found in high dose animals of both sexes, higher total
protein in high dose females. After recovery the elevated albumin levels persisted in males. All changes were
within the 95% confidence limits of the historical control data.
High dose males exhibited higher urea and lower creatinine levels which were within the 95% confidence limits
of the historical control data.
Haematology
Plasma haemoglobin concentration and haematocrit were lower in high dose animals and red blood cell count
was lower in high dose females. The toxicological significance of these findings is uncertain.
High dose animals exhibited a prolonged activated partial thromboplastin time, females had a shorter
thromboplastin time and males had a higher platelet count. All changes were within the 95% confidence limits
of the historical control data. Prolonged activated PTT and platelet counts reached statistical significance in
high dose recovery group males.
Urinalysis
Ketone was present in mid dose females and high dose animals of both sexes and was considered to be related
to the adaptive changes in lipid metabolism.
High dose females exhibited higher specific gravity and high dose animals of both sexes had slightly lower
urine production. These were within the 95% confidence limits of historical control data and may indicate a
possible change in the ability to concentrate urine.
Effects in Organs
High dose animals exhibited higher absolute and relative liver weights. These effects persisted in males at the
end of the recovery period and were considered to be treatment related yet adaptive.
High dose animals exhibited higher kidney/body weight ratios, higher absolute kidney weights and kidney to
brain weight ratio. Mid dose males also exhibited an elevated kidney/body weight ratio.
CONCLUSION
The No Observed Effect Level (NOEL) was established as 20 mg/kg bw/day in this study, based on elevated
kidney/body weight ratio in males.

TEST SUBSTANCE
METHOD OECD TG 301 B Ready Biodegradability: CO2 Evolution (Modified
Sturm) Test.
Inoculum Activated sludge from domestic wastewater treatment plant.
Exposure Period 28 days
Auxiliary Solvent None
Analytical Monitoring Analyses of inorganic carbon.
Remarks - Method The study involved exposing micro-organisms from activated sludge to 34
mg/L of the test substance. Nine test vessels were set up comprising 2
replicates each of the test item, inoculum control, procedure control
(containing sodium benzoate as a reference substance), and abiotic control
(poisoned with mercury dichloride), and 1 replicate used as a toxicity
control, containing only the test item and reference substance.
RESULTS
Test substance sodium benzoate
Day % degradation Day % degradation
10 <10 10 70
28 <10 28 83
Remarks - Results The test item was degraded by < 5% over the 28-day period, indicating
the test substance is not readily biodegradable. By comparison, the
reference substance was degraded by 70% within 7 days indicating the
test micro-organisms and test system were viable. There was no
degradation of the control, containing the test item and the poisoned test
media, indicating no abiotic degradation occurred. In addition, the test
item had no inhibitory effect on activated sludge micro-organisms, which
degraded the reference item by 41% within 14 days, indicating the
substance is not toxic to micro-organisms.
CONCLUSION The notified chemical is not readily biodegradable.
TEST FACILITY RCC (2000r).
8.1.2. Bioaccumulation
No bioaccumulation test data were provided in the notification dossier. The high fat solubility
and low molecular weight suggest the chemical has the potential to bioaccumulate. However,
under normal usage limited aqueous exposure is expected.

notified chemical, and two controls containing no test material. In
addition, they were exposed to three concentrations (5, 16 and 50 mg/L)
of a reference substance, 3,5-dichlorophenol. The test media was
prepared by adding the test material directly to deionized water, which
underwent 15 minutes of ultrasonic treatment, and 24 hours of intense
stirring at room temperature. At the two highest concentrations, some of
the test substance was observed suspended in the test media, indicating
these concentrations were above the water solubility limit. The pH
values of the test media with nominal concentrations of 25, 50, and 100
mg/L of test substance were in the range of 3.8-4.2, and therefore were
adjusted to 6.9-7.3 with sodium hydroxide.

9. RISK ASSESSMENT
9.1. Environment
9.1.1. Environment ?exposure assessment
The amount of notified chemical making its way to terrestrial or aquatic environments during its
use is difficult to determine. Release of the notified chemical at end use could occur in through
leakages or spills of the lubricant and hydraulic fluid from mobile machinery during operation
or oil changes, and through improper disposal of used oils following machinery oil changes. The
notifier has suggested the potential fate of the notified substance as follows: 25% burned in
engines, 20% re-refined, 17% burned in fuel oil, 4% incinerated, and the remaining 34%
unaccounted for. If we assume the 34% of the unaccounted used oil is disposed of improperly,
this would equate to release of 2.72 tonnes of notified chemical each year.
Use of the products containing the notified chemical are expected to occur nationwide, therefore
release will be diffuse. As such, the exposure assessment will focus on continental release into
the aquatic environment. We have calculated a very worst case scenario Predicted
Environmental Concentration (PEC) for the aquatic environment of 2.48 X 10-3 mg/L, which
assumes the maximum 2.72 tonnes of notified chemical is directly discharged into the sewer
each year. We have also assumed discharge occurs over 365 days, and that water usage is 150 L
of water per day by a population of 20 million people.
The PEC does not take into account removal from the aquatic environment by adsorption. The
chemical is not volatile, is only slightly soluble in water, and has a strong affinity to lipids,
indicating that in the sewer, the chemical will partition mainly in sludge. It is expected that most
sewage sludge will be disposed of to land or landfill, and that most of the chemical would
ultimately end up in the soil rather than in the aquatic environment. In soil environments, the log
Koc indicates that the chemical will be immobile.
At least 50% of the notified chemical could be burned either during use or disposal by
incineration. Incineration would destroy the notified chemical producing water vapour and
oxides of carbon, sulphur and phosphorus.
The notified chemical is not readily biodegraded and therefore could persist for some time in the
environment. The chemical's high partition coefficient and fat solubility indicate the substance
could cross biological membranes and bioaccumulate.
9.1.2. Environment ?effects assessment
The notifier supplied acute ecotoxicity test reports for studies conducted against fish, Daphnia,
Green algae and sewage micro-organisms. The data indicate the notified chemical is slightly
toxic to fish, Daphnia, and algae, but is not toxic to sewage microbes.
A predicted no effects concentration (PNEC) can be determined when at least one acute LC50
for each of the three trophic levels is available (ie. fish, Daphnia, algae). The PNEC is
calculated by taking the LC50 value of the most sensitive species, and dividing this value by an
assessment safety factor. The most sensitive species was Daphnia magna with a 96 hour LC50 of
24 mg/L. Using a worst case scenario safety factor of 100 (OECD), the PNECaquatic is 0.24
mg/L.
9.1.3. Environment ?risk characterisation
We have calculated the worst case scenario daily PEC of the notified chemical for the aquatic
environment to be approximately 2.48 X 10-3 mg/L if 34% were discharged into the domestic
sewer in a diffuse manner. Using the LC50 of the most sensitive species, Daphnia, and a safety
factor of 100, the PNECaquatic is 0.24 mg/L. This gives a PEC/PNEC ratio of 0.01, which is
significantly less than one, and indicates no immediate concern toward aquatic organisms.
However, given that the chemical will be used in industrial applications, where it is expected
that 100% of the lubricant will be recycled, the actual PEC is expected to be many orders of
magnitude lower than the worst case value.
FULL PUBLIC REPORT 11 September 2002
19/25
STD/1013
The calculated PEC value assumes a very worst-case situation of improper disposal and no
losses or adsorption in the sewer. However, under normal usage and proper disposal, release of
the chemical into the sewer is not anticipated. Release through improper disposal is expected to
be minimal for lubricant sold to the industrial market, where most used oils are disposed of by
recycling, burning or refining. In addition, owing to the chemical's low volatility, low water
solubility, and strong affinity to lipids, most of the chemical finding its way into the environment
would ultimately end up in the soil rather than in the aquatic environment, due to its partition
mainly into organic phases. Waste sludge is usually used in land farming or disposed of to
landfill.
In soil environments, the log Koc indicates that the chemical will be immobile. While not
readily biodegraded by sewage micro-organisms, the substance is likely to be slowly degraded
in soil environments by soil microbes and abiotic processes.
9.2. Human health
9.2.1. Occupational health and safety ?exposure assessment
Exposure to the notified chemical during transport and storage should only occur in the event of
rupture of the containers. However, this is likely to be infrequent.
The low vapour pressure of the notified chemical should preclude inhalation exposure during
transfer to the blending vessel and packing the finished lubricants and hydraulic fluids into end
use containers. Nevertheless, local exhaust ventilation is provided over the blending vessel and
during packing off should further reduce possibility of exposure to aerosols and vapours.
Following incorporation of the notified chemical into end use products at a maximum
concentration of 0.5% atmospheric levels should be negligible.
Dermal exposure during addition of the notified chemical to the blending vessel is controlled by
the use of a control valve during decanting or a closed system during pumping. Exposure to
minor drips and spills is possible during transfer and QC testing and is controlled by the use of
long PVC or nitrile gloves, eye protection and overalls. Similar potential for exposure exists
during machine maintenance and incorporation of drum residues into the blend and is controlled
in the same way by personal protective equipment. Once the notified chemical is incorporated
into end use products it is at a low concentration and exposure should be negligible.
9.2.2. Public health ?exposure assessment
The notified chemical will be imported for industrial use only, and be incorporated into
lubricating oils and hydraulic fluids at low concentrations. The end use lubricants will be
predominantly gear oils used industrially. The public may be exposed to the notified substance
during do-it-yourself lubricant changing in a vehicle. However, the exposure is infrequent,
transient and at low concentrations, and is predominantly through dermal contact. When used in
the proposed manner (with skin and eye protection), the probability of public exposure to the
notified chemical will be low, and the resulting health effects will not be significant.
9.2.3. Human health - effects assessment
The notified chemical was of low acute oral and dermal toxicity in rats, was not a skin irritant but
was a slight eye irritant in rabbits, and was neither mutagenic in bacteria nor clastogenic in
mouse bone marrow cells. It was a skin sensitiser in guinea pigs and exhibited systemic effects at
a dose of 500 mg/kg/day bw in a 28-day oral repeated dose study in rats although some of these
effects may have been adaptive in nature.
The notified chemical is classified as a hazardous substance according to the NOHSC Approved
Criteria for Classifying Hazardous Substances (NOHSC, 1999b) and is assigned the risk phrase
R43: May cause sensitisation by skin contact.
9.2.4. Occupational health and safety ?risk characterisation
The main area of concern for workers is skin sensitisation following contact with the neat
FULL PUBLIC REPORT 11 September 2002

STD/1013
chemical. This is likely to occur infrequently to workers involved in addition of the notified
chemical to the blending vessel, QC testing and maintenance of the blending equipment. The
number of events involving exposure of workers is unknown but is likely to be low. All workers
will be wearing personal protective equipment including PVC or nitrile gloves. In these
circumstances the risk of skin sensitisation is expected to be low. Once the notified chemical is
blended into end use product there should be little risk of skin sensitisation as the products
would not be classified as hazardous substances according to NOHSC criteria and would not be
assigned the risk phrase R43. Furthermore, most lubricants and hydraulic fluids containing the
notified chemical should be loaded automatically to new vehicles and there is little likelihood of
worker exposure.
9.2.5. Public health ?risk characterisation
There is a low risk of skin sensitisation in members of the public as a result of a transport
accident involving drums of the notified chemical. There is also a low risk of skin sensitisation
to members of the public arising from industrial use or disposal of the notified chemical in the
finished lubricants.
10. CONCLUSIONS ?ASSESSMENT LEVEL OF CONCERN FOR THE ENVIRONMENT
