Assessing and Managing Chemicals under TSCA

List of Manufacturer-Requested Risk Evaluations under TSCA Section 6

TSCA allows chemical manufacturers to request an EPA-conducted risk evaluation of the chemical under 40 CFR 702.31. A manufacturer may request that EPA conduct a risk evaluation for conditions of use of interest to the manufacturer. Within 60 calendar days of the receipt of a facially complete request, EPA is required to submit the request for publication in the Federal Register, open a docket for the request, and provide a public comment period of no less than 45 calendar days. After the comment period closes the Agency has 60 calendar days to either grant or deny the request.
