Identifying Chemicals for Review

Note: EPA no longer updates this information, but it may be useful as a reference or resource.


In August 2011, EPA announced plans to use a two-step process to identify chemical substances for review and assessment under the Toxic Substances Control Act (TSCA). EPA’s goal was to identify chemicals for near-term evaluation, not to screen and prioritize the entire TSCA Inventory of approximately 84,000 chemicals. EPA held a webinar and hosted an online discussion forum to get public input on the screening factors and data sources the Agency planned to use in this process.

To help structure public input, EPA posted a discussion guide describing the two-step process EPA planned to use to identify chemicals for review and requested input on the screening factors and data sources to be used for this purpose. Read the discussion guide (PDF). (8 pp. 38 kb, About PDF).

EPA conducted a webinar on September 7, 2011 to present the process and discuss the screening factors and data sources. Read the webinar slides (PDF). (15 pp. 230 kb, About PDF).

EPA also opened a discussion forum on the EPA website to allow people to share their thoughts online. The discussion forum was open for comment through 5:00 PM Eastern Daylight Time on September 21, 2011.

A summary of the discussion at the webinar and copies of all posts made through the online discussion forum were placed in the docket for this activity, EPA-HQ-OPPT-2011-0516, which is available at http://www.regulations.gov.

EPA used the public comments to refine its screening process and identified a work plan of 83 chemicals for further assessment under TSCA. EPA intends to use the TSCA Work Plan Chemicals (PDF)(11 pp, 125 kb) About PDF to help focus and direct the activities of the Existing Chemicals Program over the next several years.
