部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of ammonium acetate （CAS No. 631-61-8） when used as an inert ingredient （buffering agent） limited to 15% in pesticide formulations applied to pre-harvested crops. Exponent Inc., 1150 Connecticut Ave., Suite 1100, Washington, DC 20036 on behalf of the Gowan Company LLC., 370 South Main Street, Yuma, AZ 85364 submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting establishment of an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of ammonium acetate.
