Thank you for visiting EPA’s discussion forum on Identifying Priority Chemicals for Review and Assessment.

As part of EPA’s comprehensive approach to enhance the Agency’s current chemicals management program, the EPA Office of Pollution Prevention and Toxics (OPPT) plans to use a two-step process to identify priority chemical substances for review and assessment under the Toxic Substances Control Act (TSCA). Through this discussion forum, EPA invites you to share your thoughts on the prioritization factors and data sources the Agency is planning to use in this process. EPA will not respond directly to any comments received in this forum, but will look to this public input to help inform its process to identify candidate chemicals for near-term evaluation.

In addition to providing this discussion forum, EPA is hosting a webinar on this topic from 1:30 to 4:30 p.m. Eastern Daylight Time on September 7, 2011. Information on the webinar is available here.

This online discussion forum will remain open and available for comment until 5:00 p.m. Eastern Daylight Time (EDT) on September 14, 2011. Once the discussion forum closes, EPA will place the entire discussion forum, with comments included and attached to their associated post, in docket EPA-HQ-OPPT-2011-0516, which will be available at
