40 CFR § 702.17
Effect of designation as a high-priority substance
June 9, 2020
Final designation of a chemical substance as a High-Priority Substance under §702.11 initiates a risk evaluation pursuant to subpart B of this part. Designation as a High-Priority Substance is not a final agency action and is not subject to judicial review until the date of promulgation of the associated final rule under section 6(a). Designation as a High-Priority Substance is not a finding that the chemical substance presents an unreasonable risk.
