据美国联邦公报消息，6月13日美国环保署发布通报，豁免D-葡糖醛酸-6-脱氧-L-葡甘露聚糖-醋酸酯钙镁钾钠盐（ D-glucurono-6-deoxy-L-manno-D-glucan, acetate, calcium magnesium potassium sodium salt （diutan gum））作为农药惰性成分稳定剂/悬浮剂用于农作物或食品接触面时的残留限量要求。
本次豁免申请由Keller与Heckman公司代表斯比凯可CP Kelco U.S., Inc公司提出。
部分原文报道如下：
This regulation establishes an exemption from the requirement of a tolerance for residues of D-glucurono-6-deoxy-L-manno-D-glucan, acetate, calcium magnesium potassium sodium salt （diutan gum） Chemical Abstract Service Registration Number （（CAS Reg. No.） 595585-15-2） when used as an inert ingredient stabilizer/suspension agent applied to crops pre- and post-harvest and to food contact surfaces. Keller and Heckman on behalf of CP Kelco U.S., Inc 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 D-glucurono-6-deoxy-L-manno-D-glucan, acetate, calcium magnesium potassium sodium salt （diutan gum）。
