House Subcommittee Holds Hearing On FY 2023 Budget Request For EPA: On April 29, 2022, the House Appropriations Subcommittee on Interior, Environment, and Related Agencies held a hearing on President Biden’s fiscal year (FY) 2023 budget request for EPA. In his written testimony, EPA Administrator Michael S. Regan notes that “[c]hemicals and toxic substances are ubiquitous in our everyday lives and are often released into the environment from their manufacture, processing use, or disposal.” Regan acknowledges that EPA has “significant responsibilities” under the Frank R. Lautenberg Chemical Safety for the 21st Century Act (Lautenberg Act) amendments to TSCA to ensure the safety of chemicals in or entering commerce and to address unreasonable risks to human health or the environment. The budget would provide $124 million and 449 full-time equivalents (FTE) to implement TSCA, an increase of more than $60 million. According to Regan, “[t]hese resources will support EPA-initiated chemical risk evaluations, issue protective regulations in accordance with statutory timelines, and establish a pipeline of priority chemicals for risk evaluation.” Regan states that EPA also has “significant responsibility under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) to screen new pesticides before they reach the market and ensure pesticides already in commerce are safe.” He notes that in addition, EPA is responsible for complying with the Endangered Species Act (ESA) and ensuring that federally endangered and threatened species are not harmed when EPA registers pesticides. The proposed FY 2023 budget includes an additional $4.9 million to enable the pesticide program to integrate ESA requirements in conducting risk assessments and making risk management decisions that protect federally threatened and endangered species from exposure to new active ingredients. For more information, please see our May 2, 2022, memorandum.
