The Environmental Protection Agency (EPA) has issued a final rule granting an exemption from the requirement of a tolerance for potassium polyaspartate when used as an inert ingredient in pesticide formulations, at a maximum of 10% concentration pre-harvest. This decision means that there is no need to set a maximum legal limit for residues of this chemical in food, as it has been deemed safe. The rule is effective from March 20, 2025, and the EPA has reviewed scientific data to ensure that there is a reasonable certainty of no harm from aggregate exposure to potassium polyaspartate. The regulation does not directly affect states or tribal governments and aligns with federal standards without imposing additional mandates.
Simple Explanation
The rule says that potassium polyaspartate is okay to use in certain pesticides on food before it's picked, so there's no need to set a limit on how much is safe. The scientists checked and said it's safe, so the rule starts on March 20, 2025.
