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 
([email protected]) 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
