Under section 25(b) of the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), EPA has determined that certain "minimum risk pesticides" pose little to no risk to human health or the environment, and has exempted them from registration and other requirements under FIFRA. In April 2021, EPA issued an advance notice of proposed rulemaking (ANPRM) soliciting public comments and suggestions about the process for petitions and Agency evaluation to add or remove substances from the lists of ingredients for minimum risk pesticides. EPA also sought comment on whether the Agency should consider amending existing exemptions or adding new classes of pesticidal substances for exemption, such as peat when used in septic filtration systems. The Agency is considering the comments received and the development of a proposed rule to establish specific criteria and a petition process related to the minimum risk pesticide exemption, including how the Agency evaluates potential minimum risk active and inert substances and state implementation of the minimum risk program; factors used in classes of exemptions; and the need for any future exemptions or modifications to current exemptions. During the development of the proposed rulemaking, we intend to continue our efforts to engage all stakeholders. In addition to meetings on pesticide-specific actions, we sponsor advisory committees that include representatives of pesticide manufacturers, consumer, health, and environmental organizations, academic institutions and others. Our headquarters and regional offices partner with state, territory, and tribal governments to responsibly manage pesticide regulatory and enforcement programs.
