EPA Sets Tolerance Exemptions for Some Chemicals for Use in Pesticides

The Environmental Protection Agency set exemptions for tolerances for residues of styrene-ethylene-propylene block copolymer (here); and castor oil, polymer with adipic acid, linoleic acid, oleic acid, and ricinoleic acid (here), when used as inert ingredients in pesticide formulations. The exemptions, which are effective April 3, eliminate the need to set maximum residue limits (MRLs) for the chemicals, EPA said. Objections to the EPA’s final rule are due by June 3.
