This document establishes the following time-limited tolerances, to expire on January 1, 1998, for the residues of the herbicide bromoxynil (3,5-dibromo-4-hydroxybenzonitrile) and its metabolite DBHA (3,5-dibromo-4-hydroxybenzoic acid) resulting from the application of octanoic and heptanoic acid esters of bromoxynil to cotton: undelinted cottonseed at 7 parts per million (ppm), cotton gin byproducts at 50 ppm, and cotton hulls at 21 ppm. (Active ingredient codes are 35302 for the octanoic acid ester, and 128920 for the heptanoic acid ester. CAS Reg. Nos. are 1689-99-2 for the octanoic acid ester, and 56634-95-8 for the heptanoic acid ester.) In addition, this document revises tolerances for the residues of bromoxynil, resulting from the application of octanoic and heptanoic acid esters of bromoxynil to cotton, in or on cattle, hogs, horses, goats, and sheep to 0.5 ppm in meat, 3.0 ppm in meat by-products, and 1.0 ppm in fat. Further, this document establishes tolerances for residues of bromoxynil, resulting from the application of octanoic and heptanoic acid esters of bromoxynil to cotton, at 0.1 ppm in milk; at 0.05 ppm in eggs; and at 0.05 ppm in poultry meat, meat by-products, and fat. The tolerances for the cotton commodities will expire and are revoked on January 1, 1998. After January 1, 1998, EPA will publish a document in the Federal Register to remove the revoked tolerances from the Code of Federal Regulations. Rhone-Poulenc AG Company submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act as amended by the Food Quality Protection Act of 1996 requesting a tolerance on cottonseed.
