This regulation establishes an exemption from the requirement of a tolerance for residues of copper sulfate pentahydrate when applied as a fungicide to raw agricultural commodities after harvest. Magna Bon Corporation submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act, as amended by the Food Quality Protection Act of 1996 requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of copper sulfate pentahydrate. In this final rule, the Agency is also reordering the structure of 40 CFR 180.1001(b)(1) and 180.1021 to group most of the copper exemptions together. The reordering does not change the regulatory status of these chemicals.
