Database of Sources of Environmental Releases of Dioxin-Like
Compounds in the United States: Reference Years 1987 and 1995
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of availability of a final product.
-----------------------------------------------------------------------
SUMMARY: The National Center for Environmental Assessment within the
Office of Research and Development, U. S. Environmental Protection
Agency, announces the availability of the final Database of Sources of
Environmental Releases of Dioxin-Like Compounds in the United States:
Reference Years 1987 and 1995 (EPA/600/C-01/012, March 2001) and Users
Manual (EPA/600/R-01/012, March 2001). The database is an electronic
repository of congener-specific chlorinated dibenzo-p-dioxin and
chlorinated dibenzofuran (CDD/CDF) emissions and environmental release
data from all known sources in the United States. The database contains
information that can be analyzed to track emissions and releases of
CDD/CDF over time, compare congener-specific profiles between and among
source categories, and develop source-specific emission factors that
can then be used to estimate emissions. The information contained in
the current version of the database is associated with two reference
years: 1995 and 1987.
The structure of the database and the flow of information into and
out of the database are described in the Users Manual. The database was
created using Microsoft'' Excel 97 (hereafter, Excel) in the manner of
linked ``workbooks.'' Certain calculations and manipulations of data
performed in Excel may be lost if the database is converted to another
software; therefore, any recalculations for the data in the database
should be performed using Excel. The Excel workbooks should be
compatible with the Macintosh'' version of Excel. Because the database
and Users Manual are stored on a CD-ROM, a CD player is required for
use.
ADDRESSES: The database is available electronically through the
National Center for Environmental Assessment website at the following
URL: http://www.epa.gov/ncea. Copies of the database are also available
without cost from EPA's National Service Center for Environmental
Publications (NSCEP) in Cincinnati, Ohio (telephone: 1-800-490-9198, or
513-489-8190; facsimile 513-489-8695). When requesting a copy of the
CD-ROM, please provide your name, mailing address, and the document
number (EPA/600/C-01/012). No paper copies will be made available.
FOR FURTHER INFORMATION CONTACT: David Cleverly, National Center for
Environmental Assessment-Washington Office (8623D), U.S. Environmental
Protection Agency, Washington DC 20460 by email
(cleverly.david@epa.gov) or telephone(202-564-3238).
SUPPLEMENTARY INFORMATION: CDD/CDF emissions data were extracted from
original engineering test reports of the results of sampling the
stacks, wastewater discharges, and other emission streams at specific
facilities and sources. The database was designed to accommodate
facility-based emissions, mobile source emissions, and area source
emissions. Test reports from various state agencies, trade
associations, EPA program offices, and EPA regulatory dockets were
consolidated and assimilated into the database. Most of the emissions
data in Version 3.0 of the database concern releases to the air because
few data are currently available on releases to other media.
EPA intends to periodically update the Database of Sources of
Environmental Releases of Dioxin-Like Compounds in the United States:
Reference Years 1987 and 1995 to reflect changes in emissions of
dioxin-like compounds that may be associated with regulatory activity,
advances in pollution control, abatement, and source-specific
technologies. The next update to the database is scheduled for the fall
of 2002, and will represent emissions of dioxin-like compounds in the
United States for reference year

2000. Please consult the database website (above) for status and
availability of this update.
Dated: December 5, 2001.

Acting Director, National Center for Environmental Assessment.
