THE EMERGENCY
PLANNING AND COMMUNITY
RIGHT-TO-KNOW
ACT
EPA has prepared this brochure to alert busi-
nesses to their reporting obligations under Section
313 of the Emergency Planning and Community
Right-to-Know Act (EPCRA),' and to help you deter-
mine whether your facility is covered under the law.
If you are covered, this brochure will also help you
prepare to meet your reporting obligations. If you
are uncertain whether you are covered, it will tell
you how to get assistance.
This brochure deals with reporting requirements
of only one section of the Emergency Planning and
Community Right-to-Know Act: Section 313, which
pertains to release reporting. Other EPCRA plan-
ning and reporting requirements may also affect
your business. The nearest EPA regional office can
provide complete details, but the other basic require-
ments of EPCRA are as follows:
Facility owners/operators that have on their premises
chemicals designated under EPCRA as "extremely
hazardous substances" must cooperate with state and
local planning officials in preparing comprehensive
emergency plans (Sections 302 and 303);
Facility owners/operators must report accidental re-
leases of, "extremely hazardous substances" and
CERCLA "hazardous substances" to state and lo-
cal response officials (Section 304); and
* The Act is also known as Title III of SARA (the Superfund Amend-
ments and Reauthorization Act of 1986).
-------
Facility owners/operators must make Material
Safety Data Sheets (MSDSs) available to local and
state officials and must also report, to local and
state officials, inventories (including locations) of
chemicals on their premises for which MSDSs ex-
ist (Sections 311 and 312).
For more information on the Emergency Plan-
ning and Community Right-to-Know Act, ask your
regional EPA office for the EPCRA Fact Sheet; or
call the Emergency Planning and Community Right-
to-Know Information Hotline (800) 535-0202 or (703)
412-9877.
REPORT TOXIC
CHEMICAL RELEASES
Under Section 313 of the Emergency Planning
and Community Right-to-Know Act, certain busi-
nesses are required to submit reports each year on
the amounts of toxic chemicals their facilities re-
lease into the environment, either routinely or as a
result of accidents. The purpose of this reporting
requirement is to inform government officials and
the public about releases of toxic chemicals into the
environment. Section 313 requires facilities to
report releases to air, water, and land. The reports
must be sent to the United States Environmental
Protection Agency (EPA) and to designated state
agencies. Reports are due by July 1 each year.
Those who fail to report as required are subject to
civil penalties of up to $25,000 a day.
The final Toxic Chemical Release Inventory rule
under Section 313 was published in the Federal
Register on February 16, 1988.
WHO MUST REPORT
A plant, factory, or other facility is subject to
the provisions of Section 313 if it meets all three of
the following criteria:
It conducts manufacturing operations (is included
in Standard Industrial Classification (SIC) codes 20
through 39, listed on page 9); and
•
It has 10 or more full-time employees (or the equiva-
lent 20,000 hours per year); and
•
It manufactures, imports, processes, or otherwise
uses any of the toxic chemicals listed on pages 15-35
in amounts greater than the "threshold" quantities
specif ied below. At present, 651 chemicals and chemi-
cal categories are covered. The list may be changed in
future years.
THRESHOLDS
Thresholds are specified amounts of toxic
chemicals used during the calendar year that trig-
ger reporting requirements.
If you manufacture or import any of the listed
toxic chemicals, the threshold quantity will be:
• 25,000 pounds per toxic chemical or cat-
egory over the calendar year.
If you process any of the listed toxic chemicals,
the threshold quantity will be:
• 25,000 pounds per toxic chemical or cat-
egory over the calendar year.
If you otherwise use any of the listed toxic
chemicals (without incorporating it into any product
or producing it at the facility), the threshold quantity
is:
• 10,000 pounds per toxic chemical or cat-
egory over the calendar year.
-------
What is meant by the terms "manufacture,"
"process,"or "otherwiseuse"?
m Manufacture - means to produce, prepare, import,
or compound one of the toxic chemicals on the list.
For example, if you make a dye for clothing by tak-
ing raw materials and reacting them, you are manu-
facturing the dye. You would also be covered if
you were a textile manufacturer who imported a
dye on the list for purposes of applying it to fabric
produced at your plant.
• Process - in general, is the incorporation of a toxic
chemical into a product and includes making mix-
tures, repackaging, or using a chemical as a feed-
stock, raw material, or starting material for mak-
ing another chemical.
Examples of processing include:
a Adding a solvent as a diluent when making a
paint, coating, or other mixture;
a Using a chemical as reactant in the manu-
facture of a pesticide (e.g., using chemical A
to make chemical B).
• Otherwise Use - applies to any use of a toxic
chemical at a covered facility that is not covered
by the terms "manufacture" or "process" and in-
cludes use of a toxic chemical contained in a mix-
ture or trade name product. A toxic chemical that
is otherwise used by a facility is not intentionally
incorporated into a product distributed in com-
merce.
Examples include:
a Using a metal cutting fluid that contains
diethanolamine;
a Using a heat transfer fluid containing
biphenyl;
a Using trichloroethylene to degrease tools;
a Using chlorine in waste water treatment;
a Using Freon 113 as a refrigerant to cool pro-
cess streams.
Section 313 defines a "facility" as all buildings,
equipment, structures, and other stationary items
which are located on a single site or on contiguous
or adjacent sites and which are owned or operated
by the same person. Warehouses on the same site
as covered facilities are covered at the threshold
levels given above. Stand-alone warehouses that
do not support a manufacturing operation are not
currently covered.
The reporting thresholds apply to toxic chemi-
cals known by the owner or operator to be used in
amounts above the thresholds. Section 313 re-
quires suppliers of mixtures and trade name prod-
ucts to notify customers of the presence of Section
313 listed toxic chemicals in their products above
certain de minimis concentrations (these cutoffs are
discussed under "Exemptions"). This supplier
notification requirement has been in effect since
January 1, 1989.
EXEMPTIONS
Under certain circumstances, some or all of
the reporting requirements under Section 313 may
not apply to a facility. The following are the major
exemptions:
* De minimis concentrations of a toxic chemical in cer-
tain mixtures. In determining whether the amount of a
toxic chemical used at your facility exceeds the report-
ing threshold listed on page 3, you are not required to
count the amount of chemical present in a mixture if
its concentration is less than 1 percent of the mix-
ture, or
its concentration is less than 0.1 percent of the mix-
ture when the chemical is defined by the Occupa-
tional Safety and Health Administration (OSHA) as
carcinogenic; the chemical list beginning on page
15 identifies these chemicals.
-------
+ Articles. In considering whether a reporting thresh-
old has been exceeded, you are not required to count
toxic chemicals present in articles processed or used at
your facility. An "article" is a manufactured item: (1)
which is formed to a specific shape or design during
manufacture; (2) which has end use functions depen-
dent in whole or in part upon its shape or design during
end use; and (3) which does not release a toxic chemi-
cal under normal conditions of processing or use of that
item at the facility or establishments.
• Specified Uses. In considering whether a reporting
threshold has been exceeded, you are not required to
count toxic chemicals that are used at your facility for
any of the following purposes:
As a structural component of the facility;
in routine janitorial or facility grounds maintenance;
In foods, drugs, cosmetics, or other items for per-
sonal use, including supplies of such items (for ex-
ample, in a facility-operated cafeteria);
In motor vehicle maintenance (including motor
fuel); or
In process water and non-contact cooling water as
drawn from the environment or from municipal
sources, or in air used either as compressed air or
as part of combustion.
4 Laboratory Activities. In considering whether a re-
porting threshold has been exceeded, you are not re-
quired to count toxic chemicals that are manufactured,
processed, or otherwise used for research or quality con-
trol in a laboratory at a covered facility under the super-
vision of a technically qualified individual. This exemp-
tion does not apply to production, processing, or the
use of toxic chemicals in pilot plant scale operations and
laboratories for distribution in commerce.
4 Owners of Leased Property. The owner of a covered
facility is not subject to reporting under Section 313 if the
owner's only interest in the facility is ownership of the real
estate upon which the facility is operated. However, the
operator of the facility must report if the criteria are met.
-------
HOW TO REPORT
The owner or operator of a covered facility
must report annually. Reports must be submitted
on or before July 1 and cover activities that oc-
curred at the facility during the previous calendar
year.
EPA will provide a reporting form (EPA Form R)
with instructions and technical guidance on how to
calculate toxic chemical releases or emissions from
your facility. For information on how to obtain the
reporting form and instructions, contact the Emer-
gency Planning and Community Right-to-Know
Information Hotline. For other technical guidance,
write a letter or check the boxes for those publica-
tions on the back cover, detach the cover, and mail
it to: Emergency Planning and Community Right-
to-Know Document Distribution Center, Attn:
NCEPI, P.O. Box42419, Cincinnati, OH 45242-2419;
or any of the EPA regional offices listed on pages 13-
14.
You are not required to measure or monitor
releases for purposes of Section 313 reporting. You
may use readily available data to report the quanti-
ties of chemicals that you use and the amounts
released into the environment. If you have no data
available, the law permits you to report reasonable
estimates. EPA's technical guidance on calculating
releases can help you in making estimates.

WHAT YOU MUST REPORT
You must report on EPA Form R the following
information for each listed toxic chemical manu-
factured, imported, processed, or otherwise used
at your facility in yearly amounts which exceed the
threshold:
The name and location of your facility;
For purposes of Section 313, a release is
defined as any spilling, leaking, pumping, pouring,
emitting, emptying, discharging, injecting, escaping,
leaching, dumping, or disposing into the environ-
ment (including the abandonment or discarding of
barrels, containers, and other closed receptacles) of
any "toxic chemical" (i.e., any of the chemicals or
chemical categories on pages 15-35).
The identity of the listed toxic chemical (unless you
claim its identity to be a trade secret);
Whether you manufacture, import, process, or oth-
erwise use the toxic chemical;
•
The maximum quantity of the toxic chemical on-site
at any time during the year;
•
The total quantity of the toxic chemical released
during the year, including both accidental spills and
routine emissions - separate estimates must be pro-
vided for releases to air, water, land and injected un-
derground;
•
Off-site locations to which you shipped wastes con-
taining the toxic chemical and the quantities of that
toxic chemical sent to those locations for recycling,
energy recovery, treatment, or disposal;
•
On-site recycling, energy recovery, treatment, or
disposal methods used for wastes containing the
toxic chemical and estimates of the treatment effi-
ciency for each toxic chemical;
•
Quantities of the toxic chemical recycled, com-
busted for energy recovery, treated, and released
on-site and off-site; and
Source reduction activities involving the toxic
chemical.
PUBLIC ACCESS
TO REPORTS
The law requires facilities covered by Section
313 to send toxic chemical release reports both to
EPA and to the state in which the facility is located.
At EPA, the Office of Pollution Prevention and Toxics
is responsible for receiving and processing the
data. The agency designated to receive reports in
your state is listed in the instructions for Form R.
EPA is required by law to make the data in the
reports available to the public through a computer
database. (You can claim the toxic chemical iden-
tity to be a trade secret, but you must justify the
claim to EPA. The final Trade Secret rule was pub-
lished in the Federal Register on July 29, 1988.)
The database is intended to help answer citizens'
questions about toxic chemical releases in their
community. The users of the data are also likely to
include researchers from the government or univer-
sities conducting environmental analyses. EPA
expects to use the data in a variety of ways, includ-
ing targeting problem pollution areas and as a
screening tool for developing standards and regula-
tions.

WHAT YOU CAN DO NOW
You can begin planning now to make compli-
ance with Section 313 as easy and inexpensive as
possible. The steps are as follows:
[JJ Check that you have 10 or more full-time employ-
ees (that is, if the total annual hours worked by all
employees is at least 20,000 hours).
[J] Check the SIC code list on page 9 to determine
whether your facility is covered (i.e., has an SIC
code of 20-39).
[3] Check the list of toxic chemicals covered by Sec-
tion 313 (pages 15-35) to see if any are manufac-
tured, imported, processed, or otherwise used by
your facility. Your chemical supplier is required to
inform you if any of the Section 313 toxic chemi-
cals are contained in mixtures sold to you. Also,
the document "Common Synonyms for Section 313
Chemicals" can assist you in identifying toxic
chemicals.
|T| Determine whether you handle any toxic chemical
on the list in an amount greater than the thresh-
olds on page 3.
[5] If you meet the criteria, request copies of the re-
porting form, instructions, and any of the appro-
priate guidance documents listed on page 37 and
38.
[¥] Begin to develop the appropriate information to re-
port your releases and your source reduction and
recycling activities.
[7] Maintain a recordkeeping system that will help you
estimate releases for future years.
You should designate someone at your facility
to be responsible for reporting under Section 313.
That person should obtain reporting forms and
instructions and should be aware of the reporting
deadline: July 1 of each year.
For information on how to obtain the reporting
form and instructions, contact the Emergency Plan-
ning and Community Right-to-Know Information
Hotline. Additional guidance documents can be
obtained by mailing the order form on the inside
back cover or by calling one of the EPA regional
offices listed on pages 13-14.
