The Environmental Protection Agency has issued a final rule that exempts calcium carbonate from the requirement of a pesticide tolerance. A tolerance is a legal limit on the amount of a pesticide residue that is permitted to remain on food.

Why it matters: This is a routine administrative action. Calcium carbonate is a common mineral used as a fertilizer or soil amendment. By exempting it from tolerance requirements, the EPA simplifies the regulatory framework for this specific chemical, removing the need for agencies to monitor and enforce a specific numerical cap on its presence in food.

Who it affects

  • Columbia River Carbonates, the petitioner

This rule was published by the Environmental Protection Agency in the Federal Register; readers should consult the original document for specific implementation details and effective dates.
