Introduction
TOXIC CHEMICAL RELEASE INVENTORY
GLOSSARY OF SYNONYMS
This glossary contains chemical names and synonyms for substances covered by the
reporting requirements of section 313 of the Emergency Planning and Community Right-to-Know
Act (EPCRA) (Title I11 of the Superfund Amendments and Reauthorization Act (SARA)) (40
CFR Part 372). The glossary was developed to aid in determining whether a facility
manufactures, processes, or otherwise uses a chemical subject to section 313 reporting for the
Toxic Chemical Release Inventory (TRI).
The glossary is divided into two parts. Part I is a listing in Chemical Abstracts Service
(CAS) registry number order. The CAS number is followed by the name by which the chemical is
listed under section 313. Chemicals should be reported to TRI by their listing names. Each CAS
number and associated listing name is followed by synonyms in alphabetical order.
Part I1 of the glossary is an alphabetical list of chemical names and synonyms, with CAS
numbers. In this list, section 313 names are followed by an asterisk (*) and are footnoted as
listing names.
On November 30, 1994 (59 FR 61432), EPA added 286 new chemicals and chemical
categories to the section 313 list. Reporting of these new chemicals is required beginning with
the 1995 reporting year (first reports submitted on or before July 1, 1996). Exhibit 1 lists the 282
specific chemicals with CAS numbers added to section 313. The specific chemicals in Exhibit 1
include 20 chemicals listed as members of the diisocyanate category and 19 chemicals listed as
members of the polycyclic aromatic compounds (PAC) category. Reports for the chemicals
belonging to these categories should be for the category, not the individual chemical. These two
categories and the specific chemicals in each are shown at the end of Exhibit 1. The specific
chemicals belonging to each of these categories, and their synonyms, are included in Parts I and I1
of this glossary. The categories to which they belong are identified in footnotes. The symbol "+I'
identifies diisocyanates, and the symbol "#" identifies PACs. New chemicals that are individually
listed are also footnoted, hsing the symbol "%."
One chemical noted as belonging to the diisocyanate category,
methylenebis(pheny1isocyanate) (MDI), CAS number 101-68-8, is reportable through reporting
year 1994 as an individual chemical. Beginning in reporting year 1995, it will be reportable as
part of the diisocyanate category.
Although specific chemicals listed as diisocyanates and PACs are included in the glossary,
chemical categories that are listed under section 313 are not included. EPA did not attempt to
identify synonyms associated with chemical categories, other than the specifically listed
diisocyanates and PACs, because each category potentially includes many chemicals.
This glossary can be used to match the trade and common names of a substance to the
CAS number, the EPCRA section 313 listing name, and other synonyms. The trade or common
name can be looked up in Part 11, the alphabetical listing, to find the CAS number; the CAS
number can be looked up in Part I to find the EPCRA section 313 listing name. For example, if
the name known is Acetate Fast Orange R, this name can be found in Part I1 and the CAS
number, 82-28-0, identified. This CAS number can be found in Part I with the listing name,
1-Amino-2-methyl anthraquinone.
