Highlights
of the
Toxic Substances
Control Act

-------
Scope of the Law: The Toxic Substances Control
Act. signed into law on October 11, 1976. authorizes
the Environmental Protection Agency to obtain
production and test data from industry on selected
chemical substances and mixtures, and to regulate
the substances when needed. Chemicals used
exclusively in pesticides, food, food additives, drugs,
and cosmetics are exempted from the Act.
Testing of Chemicals: The EPA Administrator
may require manufacturers or processors of
potentially harmful chemicals to conduct tests on the
chemicals at their expense. Testing may be necessary
to evaluate a chemical's health or ecological effects
according to specified testing standards. An
interagency committee of government experts will
advise the Administrator concerning chemicals to be
tested, but his actions are not limited to those
recommended by the committee.
Premarket Notification: Manufacturers of new
chemical substances must notify the Administrator at
least 90 days before the manufacture of the chemicals
for commercial purposes. Any chemical which is not
listed on an inventory of existing chemicals to be
published by the Administrator by November 1977
will be considered "new" for purposes of the
premarket notice requirement. The Administrator
may designate a use of an existing chemical as a
significant new use. based on consideration of the
anticipated extent and type of exposure to persons or
the environment. Any person who intends to
manufacture or process a chemical for such a
significant new use must also report this information
90 days in advance of marketing. The Administrator
may issue an order and seek a court injunction, if
necessary, to keep a new chemical off the market.
This action may be taken pending development of
test data or completion of rulemaking proceedings to
ban or restrict the chemical. Among chemicals which
are or may be exempt from premarket reporting are
those (a) produced in small quantities solely for
research, (b) used for test marketing purposes, or (c)
determined not to present an unreasonable risk.

Regulation of Hazardous Chemical Substances
and Mixtures: The Administrator may prohibit or
limit the manufacture, processing, distribution in
commerce, use, or disposal of a chemical substance
or mixture if he finds that these activities present an
unreasonable risk to health or the environment.
Labelling may be required for a chemical or any
article containing the chemical.
When regulatory actions are proposed, there must
be an opportunity for comments by interested
parties, including an oral hearing, and in certain
instances, cross-examination. For imminent hazards,
the Administrator may ask a court to require
whatever action may be necessary to protect against
the risk.
Exports and Imports: The Administrator may
regulate a chemical intended for export only if it
presents an unreasonable risk to health or the
environment of the United States, if necessary to
determine whether there is such a risk, testing may
be required. The Administrator is responsible for
notifying the governments of importing countries of
any regulatory restrictions or test data submitted for
export chemicals. With respect to imports into the
United States, no chemical substance, mixture, or
article containing a chemical substance or mixture
will be allowed into this country if it fails to comply
with any rule or is otherwise in violation of the Act.
Other Provisions of the Law: Other sections
provide authority to require reporting and record-
keeping by manufacturers and processors of
chemicals; call for expanded research activities;
address the relationship of this law to other laws;
and provide for citizen civil actions and petitions. In
addition, the law requires EPA to take action to
regulate polychlorinated biphenyls (PCB's). The Act
prohibits all production of PCB's after January 1979,
and all distribution of PCB's in commerce after July
1979.
