Update to An Inventory of Sources and
Environmental Releases of Dioxin-Like
Compounds in the United States for
the Years 1987, 1995, and 2000
EPA is announcing a 30-day
public comment period for the draft
document entitled, Update to An
Inventory of Sources and Environmental
Releases of Dioxin-Like Compounds in
the United States for the Years 1987,
1995, and 2000, (EPA/600/R–11/005A).
EPA also is announcing that Versar,
Inc., an EPA contractor for external
scientific peer review, will select a
group of experts to conduct a letter peerreview of the draft document. The
document was prepared by the National
Center for Environmental Assessment
(NCEA) within EPA’s Office of Research
and Development.
In November 2006, EPA released the
report: An Inventory of Sources and
Environmental Releases of Dioxin-Like
Compounds in the United States for the
Years 1987, 1995, and 2000, (EPA/600/
P–03/002F). That report presented an
evaluation of sources and emissions of
dioxins, dibenzofurans, and coplanar
polychlorinated biphenyls to the air,
land, and water of the United States.
The inventory suggested that there was
a significant reduction in environmental
releases of dioxin-like compounds from
regulated industrial sources between the
years 1987 and 2000, and that the open
burning of residential refuse in backyard
burn barrels was the largest source in
2000 that could be reliably quantified.
This revised draft is an update to the
2006 report and reflects the additional
consideration of pre-2006 peer review.
This update does not expand the scope
of the document beyond the three
reference years covered in the 2006
document or earlier drafts: 1987, 1995,
and 2000. Changes in the updated report
reflect the addition of previously
unquantified sources and adjustments to
emission factors, for example those used
for municipal and medical waste
incinerators. The largest source added to
the inventory was emissions to air from
forest fires, a source previously
classified as preliminary and not
included in the quantitative inventory.
The updated inventory lists the top
three air sources in the year 2000 as

SUPPLEMENTARY INFORMATION:
I. Information About the Document
The purpose of this document is to
present a comprehensive inventory and
VerDate Mar<15>2010
17:03 Aug 06, 2013
Jkt 229001
an overview of sources and
environmental releases of dioxin-like
compounds in the United States. The
major identified sources of
environmental releases of dioxin-like
compounds are grouped into six broad
categories: combustion sources, metals
smelting, refining and processing
sources, chemical manufacturing
sources, natural sources, and
environmental reservoirs. Estimates of
annual releases to land, air, and water
are presented for each source category
and summarized for reference years
1987, 1995, and 2000. The quantitative
results are expressed in terms of the
toxicity equivalent (TEQ) of the mixture
of polychlorinated dibenzo-p-dioxin
(CDD) and polychlorinated
dibenzofuran (CDF) compounds present
in environmental releases using a
procedure sanctioned by the World
Health Organization (WHO) in 1998.
This TEQ procedure translates the
complex mixture of CDDs and CDFs
characteristic of environmental releases
into an equivalent toxicity
concentration of 2,3,7,8tetrachlorodibenzo-p-dioxin (2,3,7,8TCDD), the most toxic member of this
class of compounds. The total releases
under the national inventory for 1987 in
g WHO98 TEQDF (grams of dioxin toxic
equivalents (TEQs), to include only
dioxin and furan congeners (not dioxinlike PCB congeners), and determined
using the 1998 World Health
Organization’s Toxic Equivalency
Factors (TEFs)) were 15,000 to air, 2,400
to land, 360 to water, and 36 to
products. For 1995, the releases in g
WHO98 TEQDF were 3,400 to air, 2,500
to land, 30 to water, and 47 to products.
For 2000, the releases in g WHO98
TEQDF were 2,300 to air, 2,300 to land,
28 to water, and 7 to products. This
document also provides limited
estimates for releases of dioxin-like
polychlorinated biphenyls (PCBs).
In comparison to the version of this
document released in 2006, estimates of
CDD/CDF releases to air increased for
all years. The changes reflect the
addition of new sources and
adjustments to emission factors used for
municipal and medical waste
incinerators. The largest new source
added was forest fires, which was
previously classified as preliminary and
not included in the quantitative
inventory. Based on a number of new
studies, it was decided that sufficient
data were now available to move this
source into the quantitative inventory.
The forest fire releases in 2000 were
about four times higher than in 1987
and in 1995 (due to more fires) causing
a particularly large percent increase in

that year. The top three air sources in
2000 were forest fires (730 g WHO98
TEQDF), backyard barrel burning of
refuse (600 g WHO98 TEQDF), and
medical waste incinerators (400 g
WHO98 TEQDF). Other new sources
added to the present document were
secondary zinc smelters, glass
manufacturers, lime kilns, agricultural
burning, outdoor wood combustors,
aluminum foundries, copper foundries,
and septic systems.

Update to An Inventory of Sources and Environmental Releases of
Dioxin-Like Compounds in the United States for the Years 1987, 1995,
and 2000
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of public comment period and letter peer-review.
-----------------------------------------------------------------------
SUMMARY: EPA is announcing a 30-day public comment period for the draft
document entitled, Update to An Inventory of Sources and Environmental
Releases of Dioxin-Like Compounds in the United States for the Years
1987, 1995, and 2000, (EPA/600/R-11/005A). EPA also is announcing that
Versar, Inc., an EPA contractor for external scientific peer review,
will select a group of experts to conduct a letter peer-review of the
draft document. The document was prepared by the National Center for
Environmental Assessment (NCEA) within EPA's Office of Research and
Development.
In November 2006, EPA released the report: An Inventory of Sources
and Environmental Releases of Dioxin-Like Compounds in the United
States for the Years 1987, 1995, and 2000, (EPA/600/P-03/002F). That
report presented an evaluation of sources and emissions of dioxins,
dibenzofurans, and coplanar polychlorinated biphenyls to the air, land,
and water of the United States. The inventory suggested that there was
a significant reduction in environmental releases of dioxin-like
compounds from regulated industrial sources between the years 1987 and
2000, and that the open burning of residential refuse in backyard burn
barrels was the largest source in 2000 that could be reliably
quantified. This revised draft is an update to the 2006 report and
reflects the additional consideration of pre-2006 peer review. This
update does not expand the scope of the document beyond the three
reference years covered in the 2006 document or earlier drafts: 1987,
1995, and 2000. Changes in the updated report reflect the addition of
previously unquantified sources and adjustments to emission factors,
for example those used for municipal and medical waste incinerators.
The largest source added to the inventory was emissions to air from
forest fires, a source previously classified as preliminary and not
included in the quantitative inventory. The updated inventory lists the
top three air sources in the year 2000 as
[[Page 48157]]
forest fires, backyard barrel burning of refuse, and medical waste
incinerators.
EPA intends to forward the public comments that are submitted in
accordance with this notice to Versar to distribute to the external
peer-reviewers for their consideration during the letter peer-review.
When finalizing the draft document, EPA intends to consider any public
comments received in accordance with this notice. EPA is releasing this
draft assessment for the purposes of public comment and peer review.
This draft assessment is not final as described in EPA's information
quality guidelines, and it does not represent and should not be
construed to represent Agency policy or views.
The draft document is available via the Internet on the NCEA home
page under the Recent Additions and the Data and Publications menus at
www.epa.gov/ncea.
DATES: The 30-day public comment period begins August 7, 2013, and ends
September 6, 2013. Technical comments should be in writing and must be
received by EPA by September 6, 2013.
ADDRESSES: The draft document, Update to An Inventory of Sources and
Environmental Releases of Dioxin-Like Compounds in the United States
for the Years 1987, 1995, and 2000, is available primarily via the

SUPPLEMENTARY INFORMATION:
I. Information About the Document
The purpose of this document is to present a comprehensive
inventory and an overview of sources and environmental releases of
dioxin-like compounds in the United States. The major identified
sources of environmental releases of dioxin-like compounds are grouped
into six broad categories: combustion sources, metals smelting,
refining and processing sources, chemical manufacturing sources,
natural sources, and environmental reservoirs. Estimates of annual
releases to land, air, and water are presented for each source category
and summarized for reference years 1987, 1995, and 2000. The
quantitative results are expressed in terms of the toxicity equivalent
(TEQ) of the mixture of polychlorinated dibenzo-p-dioxin (CDD) and
polychlorinated dibenzofuran (CDF) compounds present in environmental
releases using a procedure sanctioned by the World Health Organization
(WHO) in 1998. This TEQ procedure translates the complex mixture of
CDDs and CDFs characteristic of environmental releases into an
equivalent toxicity concentration of 2,3,7,8-tetrachlorodibenzo-p-
dioxin (2,3,7,8-TCDD), the most toxic member of this class of
compounds. The total releases under the national inventory for 1987 in
g WHO98 TEQDF (grams of dioxin toxic equivalents (TEQs), to include
only dioxin and furan congeners (not dioxin-like PCB congeners), and
determined using the 1998 World Health Organization's Toxic Equivalency
Factors (TEFs)) were 15,000 to air, 2,400 to land, 360 to water, and 36
to products. For 1995, the releases in g WHO98 TEQDF were 3,400 to air,
2,500 to land, 30 to water, and 47 to products. For 2000, the releases
in g WHO98 TEQDF were 2,300 to air, 2,300 to land, 28 to water, and 7
to products. This document also provides limited estimates for releases
of dioxin-like polychlorinated biphenyls (PCBs).
In comparison to the version of this document released in 2006,
estimates of CDD/CDF releases to air increased for all years. The
changes reflect the addition of new sources and adjustments to emission
factors used for municipal and medical waste incinerators. The largest
new source added was forest fires, which was previously classified as
preliminary and not included in the quantitative inventory. Based on a
number of new studies, it was decided that sufficient data were now
available to move this source into the quantitative inventory. The
forest fire releases in 2000 were about four times higher than in 1987
and in 1995 (due to more fires) causing a particularly large percent
increase in that year. The top three air sources in 2000 were forest
fires (730 g WHO98 TEQDF), backyard barrel burning of refuse (600 g
WHO98 TEQDF), and medical waste incinerators (400 g WHO98 TEQDF). Other
new sources added to the present document were secondary zinc smelters,
glass manufacturers, lime kilns, agricultural burning, outdoor wood
combustors, aluminum foundries, copper foundries, and septic systems.
