SECTION 313
List of Toxic Chemicals



This document provides a quick reference list of the toxic chemicals for which reporting is
required under Section 313 of the Emergency Planning and Community Right-to-Know Act (EPCRA)
(also referred to as the Toxics Release Inventory (TRI)). More specific information on the EPCRA
section 313 reporting requirements can be found in the EPA document, "The Emergency Planning and
Community Right-to-Know Act: Section 313 Release and Other Waste Management Reporting
Requirements" (EPA 260/K-01-001), available on the TRI Internet site at:

Section 1. Introduction

The final rule implementing the reporting requirements of EPCRA section 313 was published in
the Federal Register on February 16, 1988 (53 FR 4500) (40 CFR 372) and contained a list of more
than 320 toxic chemicals and toxic chemical categories. Under EPCRA section 313(d) chemicals may
be added to or deleted from the list of reportable toxic chemicals. This document contains the EPCRA
section 313 list of toxic chemicals as reportable at the time of publication of this document (February
2001). The EPCRA Information Hotline ((800) 424-9346 or (703) 412-9810) and the TRI Internet
site (http://www.epa.gov/tri), will provide up-to-date information on the status of any changes to the
EPCRA section 313 list of reportable toxic chemicals.

Qualifiers

Certain toxic chemicals listed on EPCRA section 313 have parenthetic "qualifiers." These
qualifiers indicate that these toxic chemicals are subject to the section 313 reporting requirements if
manufactured, processed, or otherwise used in a specific form or when a certain activity is performed.
The following chemicals are reportable only if they are manufactured, processed, or otherwise used in
the specific form(s) listed below:
Chemical CAS Number Qualifier
Aluminum (fume or dust) 7429-90-5 Only if it is in a fume or dust
form.
Aluminum oxide (fibrous forms) 1344-28-1 Only if it is a fibrous form.
Ammonia (includes anhydrous ammonia 7664-41-7 Only 10 percent of aqueous
and aqueous ammonia from water forms. 100 percent of anhydrous
dissociable ammonium salts and other forms.
sources; 10 percent of total aqueous
ammonia is reportable under this listing)

Asbestos (friable) 1332-21-4 Only if it is a friable form.


Hydrochloric acid (acid aerosols 7647-01-0 Only if it is an aerosol form as
including mists, vapors, gas, fog, and defined.
other airborne forms of any particle size)


Phosphorus (yellow or white) 7723-14-0 Only if it is a yellow or white
form.
Sulfuric acid (acid aerosols including 7664-93-9 Only if it is an aerosol form as
mists, vapors, gas, fog, and other defined.
airborne forms of any particle size)



2
Chemical CAS Number Qualifier
Vanadium (except when contained in an 7440-62-2 Except if it is contained in an
alloy) alloy
Zinc (fume or dust) 7440-66-6 Only if it is in a fume or dust
form.

The qualifier for the following two chemicals is based on the chemical activity rather than the
form of the chemical. These chemicals are subject to EPCRA section 313 reporting requirements only
when the indicated activity is performed.
Chemical/Chemical Category CAS Number Qualifier
Dioxin and Dioxin-Like Compounds NA Only if they are manufactured at the
(Manufacturing; and the processing or facility; or are processed or
otherwise use of dioxin and dioxin-like otherwise used when present as
compounds if the dioxin and dioxin-like contaminants in a chemical but only
compounds are present as contaminants if they were created during the
in a chemical and if they were created manufacture of that chemical.
during the manufacture of that chemical.)
Isopropyl alcohol (manufacturing - 67-63-0 Only if it is being manufactured by
strong acid process, no supplier the strong acid process.
notification)
Saccharin (manufacturing, no supplier 81-07-2 Only if it is being manufactured.
notification)

There are no supplier notification requirements for isopropyl alcohol and saccharin since the
processors and users of these chemicals are not required to report. Manufactures of these chemicals
do not need to notify their customers that these are reportable EPCRA section 313 chemicals.

De minimis

In the final rule that implemented the reporting requirements of EPCRA section 313 (53 FR
4500, February 16, 1988), EPA adopted a de minimis exemption which, under certain conditions,
permits facilities to disregard de minimis levels of toxic chemicals for threshold and reporting
calculations. The rule adopted a 1.0% de minimis level for all chemicals except those which are
carcinogens, as defined in 29 CFR 1910.1200(d)(4), which have a 0.1% de minimis level. This
section of the CFR reads as follows:

"(4) Chemical manufacturers, importers and employers evaluating chemicals shall treat the
following sources as establishing that a chemical is a carcinogen or potential carcinogen for
hazard communication purposes:

3
(i) National Toxicology Program (NTP), Annual Report on Carcinogens
(latest edition);
(ii) International Agency for Research on Cancer (IARC) Monographs
(latest editions); or
(iii) 29 CFR part 1910, subpart Z, Toxic and Hazardous Substances,
Occupational Safety and Health Administration."

The de minimis levels listed in this document are based on the most current IARC and NTP published
editions and the current listings under 29 CFR part 1910, subpart Z. However, the de minimis levels
that were in effect for any given reporting year may be different than those in this document. This is
because any changes of an IARC or NTP classification of a chemical are effective for the next
reporting year after the latest editions of the IARC Monographs or NTP Annual Reports are published.


PBT chemicals

On October 29, 1999 (64 FR 58666), EPA issued a final rule that designated certain listed
toxic chemicals as persistent bioaccumulative toxic (PBT) chemicals and on January 17, 2001 (66 FR
4500), EPA issued a final rule designating lead and lead compounds as PBT chemicals. In addition to
lower reporting thresholds and other requirements, the de minimis exemption cannot be taken for PBT
chemicals. Thus, de minimis concentration levels for the PBT chemicals are not provided in this
document.

Section 4. Chemical Categories

EPCRA section 313 requires reporting on the toxic chemical categories listed below, in
addition to the specific toxic chemicals listed in the sections above.

The metal compound categories listed below, unless otherwise specified, are defined as
including any unique chemical substance that contains the named metal (e.g., antimony, nickel, etc.) as

Toxic chemical categories are subject to the 1.0 percent de minimis concentration unless the
substance involved meets the definition of an OSHA carcinogen in which case the 0.1 percent de
minimis concentration applies. The de minimis concentration for each category is provided in
parentheses. PBT chemicals do not have de minimis concentrations and are marked with an NA (not
applicable) in parentheses.
