EPA promulgated a final rule to revise the federal regulations issued under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) that direct agricultural worker protection (40 CFR 170). The changes are in response to extensive stakeholder review of the regulation and its implementation since 1992, and reflect current research on how to mitigate occupational pesticide exposure to agricultural workers and pesticide handlers. The EPA strengthened the protections provided to agricultural workers and handlers under the worker protection standard by improving elements of the existing regulation, such as training, notification, communication materials, use of personal protective equipment, and decontamination supplies. The EPA expects the revisions to prevent unreasonable adverse effects from exposure to pesticides among agricultural workers and pesticide handlers; vulnerable groups, such as minority and low-income populations, child farmworkers, and farmworker families; and the general public. The EPA recognizes the importance and independence of family-owned farms and therefore expanded the definition of immediate family” and continued the exemption from many provisions of the WPS for owners of such farms and members of their immediate families.
