据美国政府网站消息，9月9日美国环保署（EPA）发布通告，豁免丙二醇单甲醚（Propylene Glycol Monomethyl Ether）在农作物中的最大残留限量。
按照美国联邦法令要求，先正达公司（Syngenta Crop Protection）发布申请，请求豁免该农药的最大残留限量。经过评估，美国环保署认为没必要制定丙二醇单甲醚在农作物中的残留限量。
本条例于发布之日起生效，征求意见截止日期为2015年11月9日。
部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of propylene glycol monomethyl ether （PGME; CAS No. 107-98-2） when used as an inert ingredient under 40 CFR 180.910 as a solvent in pesticide formulations which include pre-and post-harvest use on crops. Syngenta Crop Protection 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 PGME.
