EPA is announcing legally mandated changes to the fee requirements under TSCA. TSCA directs EPA to adjust the fees every three years. Accordingly, an adjustment will go into effect on 1 January 2022, and will apply to all TSCA fees. In a separate action, in 2022, EPA plans to propose additional revisions to the 2018 TSCA fees rule to supplement the agency’s proposal from 11 January 2021 to ensure that TSCA fee amounts capture up to 25% of the actual costs of TSCA activities, fees are distributed equitably, and fee payers are identified through a transparent process.
