EPA is providing web access to the Toxic Substances Control Act (TSCA) Chemical Substance Inventory. This inventory contains a consolidated list of thousands of industrial chemicals maintained by the agency. EPA is also making this information available on Data.Gov, a website developed by the Obama Administration to provide public access to important government information.
Until now, the consolidated public portion of the TSCA Inventory has only been available by purchase from the National Technical Reports Library or other databases. By adding the consolidated TSCA Inventory to the Agency’s website and to Data.Gov, EPA is making this information readily available to the public at no cost.
Currently, there are more than 84,000 chemicals manufactured, used, or imported in the U.S. listed on the TSCA Inventory. The EPA argues they are unable to publicly identify nearly 17,000 of these chemicals because the chemicals have been claimed as confidential business information under TSCA by the manufacturers. Therefore, the EPA argues the need and have already begun a series of aggressive steps, including an announcement in January that signaled EPA’s intent to reduce a certain type of confidentiality claim, or Confidential Business Information (CBI) claim, on the identity of chemicals
In the coming months, EPA will take further steps, including adding TSCA facility information, and the list of chemicals manufactured to the Facility Registry System (FRS). FRS is an integrated database that provides the public with easier access to EPA’s environmental information and better tools for cross-media environmental analysis.
