据美国联邦公报消息，7月20日美国联邦公报发布通告，豁免一种农药助剂的最大残留限量。
该种农药助剂为2-丙烯酸，丁酯，乙酸乙烯酯钠盐聚合物（2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate）。本次申请由Celanese Ltd 公司提交。美国环保署经评估，认为没必要制定食品与饲料中有关的限量。
部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of 2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate （CAS Reg. No. 66573-43-1） when used as an inert ingredient in a pesticide chemical formulation. Celanese Ltd submitted a petition to EPA under the Federal Food, Drug, and Cosmetic Act （FFDCA）， requesting an exemption from the requirement of a tolerance. This regulation eliminates the need to establish a maximum permissible level for residues of 2-propenoic acid, butyl ester, polymer with ethenyl acetate and sodium ethenesulfonate on food or feed commodities.
