EPN Writes Letter on Enhancing Use of EPA’s Testing Authority Under TSCA Section 4

On February 26, 2021, EPN sent a letter to the EPA Principal Deputy Assistant Administrator for Chemical Safety and Pollution Prevention expressing concern that the agency has not effectively utilized the expanded authority granted by Congress under Section 4 of the amended Toxic Substances Control Act (TSCA) to improve the science base for risk evaluations and other assessments under the law. This amendment gives EPA authority to issue test orders as well as rules to require manufacturers and processors to generate information on the risks of chemical substances and mixtures. EPN strongly recommends that EPA modify its existing chemical prioritization and risk evaluation process under TSCA to include a systematic mechanism for comprehensive data adequacy analysis on candidate chemicals before they advance to prioritization and risk evaluations.
