Toxic Substances Control Act of 1976

From WikiMD.com Medical Encyclopedia




The Toxic Substances Control Act of 1976 (TSCA) is a United States law, administered by the Environmental Protection Agency (EPA), that regulates the introduction of new or already existing chemical substances. It was enacted by the 94th United States Congress and signed into law by President Gerald Ford on October 11, 1976.

Overview[edit | edit source]

The TSCA grants the EPA authority to require reporting, record-keeping, and testing requirements, and restrictions relating to chemical substances and/or mixtures. Certain substances are generally excluded from TSCA, including, among others, food, drugs, cosmetics, and pesticides.

The TSCA addresses the production, importation, use, and disposal of specific chemicals including polychlorinated biphenyls (PCBs), asbestos, radon, and lead-based paint.

Key Provisions[edit | edit source]

Existing Chemicals[edit | edit source]

Under TSCA, the EPA is responsible for reviewing and regulating existing chemicals. The agency maintains the TSCA Chemical Substance Inventory, which lists all existing chemical substances manufactured or processed in the United States. The EPA can require testing of chemicals to gather data on their effects on health and the environment.

New Chemicals[edit | edit source]

Before a new chemical can be manufactured or imported, the manufacturer must submit a Pre-Manufacture Notice (PMN) to the EPA. The agency then assesses the potential risks associated with the chemical. If the EPA identifies potential risks, it can impose restrictions or require further testing.

Polychlorinated Biphenyls (PCBs)[edit | edit source]

PCBs are a group of man-made organic chemicals that were widely used in industrial and commercial applications. The TSCA banned the manufacture of PCBs in 1979 and regulates their disposal.

Asbestos[edit | edit source]

Asbestos is a naturally occurring mineral fiber that has been used in a variety of building construction materials for insulation and as a fire retardant. The TSCA regulates the use and disposal of asbestos to protect public health.

Lead[edit | edit source]

Lead is a toxic metal that was once used in products found in and around homes, including paint. The TSCA includes provisions for the reduction of lead exposure, particularly in residential settings.

Amendments[edit | edit source]

The TSCA has been amended several times, most notably by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in 2016, which significantly overhauled the law to improve the safety of chemicals in commerce.
