This regulation establishes exemptions from the requirement of a tolerance for residues of dibasic esters (DBE; CAS Reg. No. 95481-62- 2) when used as an inert ingredient solvent and/or anti-freeze microencapsulated at 10% weight/weight (W/W) or less in pesticide formulations with the active ingredient cyfluthrin. Whitmire Micro-Gen Research Laboratories, Inc. submitted a pesticide petition 5E4442 to EPA under the Federal Food, Drug, and Cosmetic Act (FFDCA) requesting exemptions from the requirement of a tolerance. EPA published in the Federal Register on August 29, 2007 (72 FR 49689) a proposed rule for this petition in order to provide the public with an opportunity to comment on data that submitted to the Agency after the publication of the petition's Notice of Filing.
