TSCA
The Federal Toxic Substances Control Act (TSCA 15
U.S. Code 2601) was enacted by Congress on October 11, 1976. This Public
Law (94-469) was enacted to "regulate commerce and protect human
health and the environment by requiring testing and necessary use
restrictions on certain chemical substances, and for other
purposes". Recognizing in 1976 that insufficient data existed with
respect to the effects of chemical substances and mixtures on human
health, Congress authorized the administrator of the EPA to track the
70,000 industrial chemicals currently produced or imported in the U.S.
REGULATION OF SPECIFIC
CHEMICALS UNDER TSCA
dibenzodioxins and dibenzofurans (contaminants
present at Times Beach, MO);
asbestos and asbestos-containing materials;
fully halogenated chlorofluorocarbons (CFCs—once
used as aerosol propellants, responsible for ozone depletion in the
upper atmosphere);
Polychlorinated biphenyls (PCBS)
ASBESTOS
Asbestos is a unique mineral due to the fact that
it will turn into dust particles when crushed and will fracture into
ultra-fine fibers that may only be observed with a microscope. Often
asbestos fibers are processed with a binding agent that holds them
together, producing an asbestos containing material (ACM) that is both
flexible and fire resistant. However, if the structural integrity of the
asbestos containing material is compromised the asbestos may become
airborne, and when inhaled may remain in the lungs for a long period of
time. This will present a potential risk for severe health problems with
a possible long latency period
PCBs
Polychlorinated biphenyls (PCBs) are a class of
synthetic organic chemicals that contain 209 individual chlorinated
chemicals (known as congeners). PCBs may be either oily liquids or
solids of a light yellow or colorless appearance. They are both odorless
and tasteless. PCB mixtures may also be referred to in the United States
by their industrial trade name, Arochlor
RADON
Radon is a naturally occurring gas that seeps out
of rocks and soil. Radon originates from the element uranium. The rate
of radon seepage varies by geographic region, partly because the amounts
of uranium in the soil are considerably different. Radon escapes from
the ground into outdoor air and also into the indoor air environment of
homes via underground levels (basements). Outdoor radon is not viewed as
a problem due to the high rate of mixing with cleaner radon free ambient
air. In contrast, among indoor environments radon concentrations can
exceed safe levels and may pose a serious health hazard.
LABELING
HOUSEHOLD HAZARDOUS CHEMICALS
The Consumer Products Safety Commission (CPSC) is
required under HSA to evaluate substances for these hazardous
characteristics and to identify those substances that are hazardous.
CPSC must include those substances already defined as hazardous by other
programs, such as the Occupational Safety and Health Administration (OSHA)
regulations and EPA regulations of hazardous wastes. HSA requires CPSC
to follow certain notice and hearing procedures when considering whether
to define a substance as hazardous. CPSC
regulations prescribe tests for assessing whether products are
hazardous, and how to accurately label them.
Insecticides, foods, drugs and cosmetics; fuels used domestically; and
radioactive materials are currently regulated by other laws and are
specifically excluded from the labeling acts
