As the federal government endures another prolonged shutdown, uncertainty is rippling through every agency, with the impact clearly visible at the U.S. Environmental Protection Agency (EPA). With only a fraction of staff on duty and most routine operations halted, the chemical and pesticide regulatory landscape faces a new round of challenges in both the Office of Pollution Prevention and Toxics (OPPT) and the Office of Pesticide Programs (OPP). EPA’s September 29, 2025, contingency plan...

As Congress edges closer to another potential government shutdown, questions loom large about how federal agencies will manage critical regulatory responsibilities. For the U.S. Environmental Protection Agency (EPA), even a short lapse in appropriations and critical staffing could have significant consequences for the implementation of the Toxic Substances Control Act (TSCA). TSCA is built around statutory deadlines. For example, there are strict timelines for new chemical reviews under Section...
