部分原文報道如下：
This regulation establishes exemptions from the requirement of a tolerance for residues of isobutyl acetate （CAS Reg. No. 110-19-0） and isobutyric acid （CAS Reg. No. 79-31-2） when used as inert ingredients （solvent） in pesticide formulations applied to growing crops and raw agricultural commodities after harvest. Technology Sciences Group Inc. on behalf of Jeneil Biosurfactant Company submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting establishment of these exemptions from the requirement of a tolerance. This regulation eliminates the need to establish maximum permissible levels for residues of isobutyl acetate and isobutyric acid.
