Toxic Substances Control Act Of 1976
The Toxic Substances Control Act (TSCA) is a United States law, passed by the United States Congress in 1976, that regulates the introduction of new or already existing chemicals. It grandfathered most existing chemicals, in contrast to the Registration, Evaluation and Authorization of Chemicals (REACH) legislation of the European Union. However, as explained below, the TSCA specifically regulates polychlorinated biphenyl (PCB) products.
Contrary to what the name implies, TSCA does not separate chemicals into categories of toxic and non-toxic. Rather it prohibits the manufacture or importation of chemicals that are not on the TSCA Inventory (or subject to one of many exemptions). Chemicals that are listed on the TSCA Inventory are referred to as "existing chemicals". Chemicals not listed are referred to as new chemicals. Generally, manufacturers must submit premanufacturing notification to the U.S. Environmental Protection Agency (EPA) prior to manufacturing (or importing) new chemicals for commercial purposes. There are notable exceptions, including one for research and development, and for substances regulated under other statutes such as the Federal Food, Drug, and Cosmetic Act and the Federal Insecticide, Fungicide, and Rodenticide Act.
New chemical notifications are reviewed by the agency and if the agency finds an "unreasonable risk to human health or the environment," it may regulate the substance in a variety of ways, from limiting uses or production volume to outright banning them.

“The human mind is indeed a cave swarming with strange forms of life, most of them unconscious and unilluminated. Unless we can understand something as to how the motives that issue from this obscurity are generated, we can hardly hope to foresee or control them.”

“It is in the very nature of things human that every act that has once made its appearance and has been recorded in the history of mankind stays with mankind as a potentiality long after its actuality has become a thing of the past.”
