-------
This document is a compilation of tables for the data extraction and evaluation for Cyclic
Aliphatic Bromides Cluster (HBCD). Each table shows the data point or set or information
element that was extracted and evaluated from a data source in accordance with Appendix D
of the Application of Systematic Review in TSCA Risk Evaluations. If the source contains more
than one data set or information element, the review provides an overall confidence score for
each data set or information element that is found in the source. Therefore, it is possible that a
source may have more than one overall quality/confidence score.

Information from industry shows that, in 1992, out of the total
construction- and demolition (C&D) waste, plastic waste was 0.4 per-
cent of the weight. EPS and XPS were representing about 3 percent of
the plastic waste and therefore 0.01 percent of the total building waste.

** Consistent with our Application of Systematic Review in TSCARisk Evaluations document, if a metric for a data source receives a score of Unacceptable (score = 4),
EPA will determine the study to be unacceptable. In this case, one of the metrics were rated as unacceptable. As such, the study is considered unacceptable and the
score is presented solely to increase transparency.

EPS and XPS insulation

EPS and XPS materials were respectively blended with refuse derived
fuel (RDF) as input wastes for incineration. Concentrations of HBCDs
contained in the EPS- and XPS-added RDFs, were 140 and 1100 mg kg
1, respectively.

Incineration destruction experiment

During the incineration experiments with EPS and XPS, primary and
secondary combustion zones were maintained at temperatures of 840 C
and 900 C. The residence times of waste in the primary combustion
zone and flue gas in the secondary combustion zone was 30 min and
three seconds, respectively.

Concentration levels of the total HBCDs in the bag filter exit gas for
the two experiments with EPS and XPS were 0.7 and 0.6 ng/m3, re-
spectively. HBCDs were also not detected (<0.2 ng/g) in the bottom
and fly ash samples. From the obtained results, it was calculated that
HBCDs were sufficiently destroyed in the whole incineration process with
destruction efficiencies of more than 99.9999 for both of EPS and XPS

** Consistent with our Application of Systematic Review in TSCARisk Evaluations document, if a metric for a data source receives a score of Unacceptable (score = 4),
EPA will determine the study to be unacceptable. In this case, one of the metrics were rated as unacceptable. As such, the study is considered unacceptable and the
score is presented solely to increase transparency.

Unacceptable 4 Metric Mean Score: 1.9.



** Consistent with our Application of Systematic Review in TSCARisk Evaluations document, if a metric for a data source receives a score of Unacceptable (score = 4),
EPA will determine the study to be unacceptable. In this case, one of the metrics were rated as unacceptable. As such, the study is considered unacceptable and the
score is presented solely to increase transparency.

* MWF = Metric Weighting Factor

I If any individual metrics are deemed Unacceptable, then the overall rating is also unacceptable. Otherwise, the overall rating is based on the following scale:

High: > 1 to < 1.7; Medium: > 1.7 to < 2.3; Low: > 2.3 to < 3.

Life Cycle Stage:

Life Cycle Description (Subcategory of Use):

Processing

Formulation of XPS and converting of XPS

Workers in the formulation industry, that is those involved in the formu-
lation of flame retarded resins, have the greatest risk of exposure since
they weigh, transfer and mix the solid powder or liquid resins contain-
ing pure/concentrated PBFRs. Downstream fabricators who handle the
formulated resins, emulsions and/or polymers are also expected to be
exposed to the PBFRs. Dermal contact is the main route of exposure
resulting from contact with these solutions. Given that the PBFRs are
non-volatile, exposure by inhalation is expected to be minimal when
handling liquid resins. However, potential for exposure by inhalation of
dust generated while handling powder compounds is high. Some release
of volatile, thermal degradation products of some PBFRs may occur
during moulding of polymer at processing temperatures.

** Consistent with our Application of Systematic Review in TSCARisk Evaluations document, if a metric for a data source receives a score of Unacceptable (score = 4),
EPA will determine the study to be unacceptable. In this case, one of the metrics were rated as unacceptable. As such, the study is considered unacceptable and the
score is presented solely to increase transparency.

it is added to a hopper that feeds into the polystyrene melt. Further
potential exposure to HBCDDcontained within polystyrene dust may
also occur during secondary processing of XPS and during the shredding

Exterior operations (deploying hose, forcible entry), overhaul operations,
PPE ensembles could also become contaminated with these compounds
and then transferred to the skin. Because some flame retardants, diox-
ins, and furans are highly persistent, they could accumulate on gear over
time and transfer to the skin of firefighters where they may be dermally
absorbed or ingested. Another possible exposure pathway is from the
particulate and vapors produced during a fire that may penetrate or per-
meate the protective barriers of the turnout gear and directly contact the
skin. Studies have demonstrated that neck and hands are particularly
vulnerable to this exposure pathway

Firefighters generally wear a self-contained breathing apparatus (SCBA),
but do not always wear SCBA during exterior operations (deploying
hose, forcible entry, outside vent) or during overhaul operations

sured levels of PBDEs were 2 to 3 times the levels detected in the general
US population.

serum concentrations (blood samples)

Of major concern during fires is the potential formation of large amounts
of by-products such as chlorinated and brominated dibenzo-p-dioxins
and dibenzofurans (PCDD/Fs and PBDD/Fs)...In industrial countries,
PBDD/Fs are released from uncontrolled burning of BFR-containing
wastes and the resulting emissions contribute substantially to total
dioxin-like toxicity...Tentative TEQs calculated for PBDD/Fs suggested
that these compounds may contribute substantially to dioxin-like tox-
icity in individual firefighters. The elevated concentrations of PBDEs
in the California firefighters relative to US population concentrations
and the distinctive PBDE and PFC congener patterns in serum are sug-
gestive of significant occupational exposure to these compounds during
firefighting.

inhalation, dermal absorption, and ingestion

Exposure through lungs, mouth, and skin may occur during contact with
smoke and soot. Fumes, gases, and small inhaled particles reach deep
into the lungs where flame retardants may be absorbed into blood. Some
chemicals may move through layers of skin when soot is deposited on
exposed skin.

Firefighters may be exposed to flame retardants to a greater extent
and in different ways than the general population. Firefighters may
be exposed to chemicals, including flame retardants and combustion by-
products, during a fire, during overhaul (searching for fire extending
into building spaces), or cleaning firefighting equipment. Firefighters
may be exposed through contact with contaminated vehicles, clothing
and equipment, and firehouses. Source provides a description of how the
combustion of halogenated flame retardants increases the potential for
exposure to a variety of compounds.

EPS articles from beads

EPS pellets are converted to expanded beads using steam. The ex-
panded beads can then be moulded into boards and shapes (e.g. insu-
lation boards). The temperature softens the beads and the expansion
of blowing agent they contain (i.e. pentane) causes the pellets/beads to
expand up to 50 times their original size. More details in Section 9.3.1.1

Formulation of resins containing the flame-retardant chemicals consists
of weighing or pumping, mixing and blending, processing/extrusion and
cutting and packaging of the granular pellets or liquid resins. The
PBFRs are compounded with the appropriate polymer (polypropylene
or polystyrene) to produce a masterbatch containing up to 30 percent of
the flame-retardant. It is possible that more than one flame-retardant
chemical may be used in the formulation process.

Manufacture of XPS Using HBCD Powder

In the blending plant, weighed amounts of the powdered or granulated
polymeric material are transferred to rotary mixers/blenders. Weighing
is a manual process, whereby workers transfer the flame retardant by
tipping the drums or bags in specially designed dispensary. Weighed
quantities of flame retardant, pigment and other additives are added
either via a closed transfer system or through a chute with a vacuum
collar or under local exhaust ventilation to remove dust.The blended
material is discharged to a collection bin, usually either in an enclosed
system or under local exhaust ventilation and transferred to an extruder,
whereby the mixture is extruded under high temperatures to form strips,
which are cooled then cut into small pellets or granules with the desired
concentration of flame retardant. These are bagged and dispatched to
customers.

Auto replacement parts

Our members have indicated to us that this chemical is not used during
the auto manufacturing process. HBCD has been aggressively phased
out by the auto industry over the past several years. However, the
chemical may still be used by some automakers as a flame retardant in
coatings of certain components (e.g., dashboards and headliners) and in
solder paste in interior components (e.g., circuits). This chemical may
also be present in adhesives and foams.

Our members, in an effort to provide duediligence, have reviewed avail-
able data related to the use of HBCD and have not identified any on-
going uses inthe manufacture of new vehicles. However, both CASRNs
25637-99-4 and 3194-55-6 have been and arecurrently being used in the
manufacture of replacement parts only-replacement parts designed prior
to the dateof publication of the HBCD scoping document and, more
importantly, prior to the publication of any rulemaking in the Federal

The main use of HBCD is as a flame retardant in expanded polystyrene
foam (EPS) and extruded polystyrene foam (XPS). There is little pub-
lished information about the distribution of HBCD in the United States;
however, data for the European Union (EU) market shows that about 96
percent of HBCD is used in EPS and XPS (ECHA, 2009). HBCD may
also be used as a flame retardant in textiles. In addition, HBCD is used
as a flame retardant in high impact polystyrene (HIPS) for electrical and
electronic appliances.

This analysis assumes a total import/production volume of 10-50 million
pounds for HBCD, as reported in the 2006 IUR (U.S. EPA, 2006).
EPS boards contain approximately 0.5-0.7 percent HBCD by weight,
while XPS insulation contains approximately 0.8-2.5 percent HBCD by
weight (UNEP, 2011).
