IFCA Asks Our Member to Submit Comments on Atrazine

IFCA is urging our ag retail members to submit comments in support of protecting Atrazine. While the EPA has made some positive changes, flawed studies and modeling still threaten to impose costly mitigation requirements on 68% of U.S. corn acres. If the EPA used more realistic studies, only 13% of acres would need these costly actions.
 
Ag retailers and growers have the opportunity to make their voices heard by the EPA to protect atrazine and help minimize expensive mitigation measures. It's crucial that everyone in the ag input industry in Illinois send comments before the April 4 deadline.

Atrazine is a critical tool for ag retailers to help our farmer customers. While EPA’s Updated Mitigation Proposal makes progress, it still falls short in the science behind the aquatic level of concern and the data used to designate mitigation areas.

I appreciate EPA’s willingness to listen to ag retailers. The agency’s acceptance of the Scientific Advisory Panel’s recommendations led to an aquatic level of concern (CELOC) of 9.7 parts per billion— nearly triple the previous 3.4 ppb. However, some low-quality studies are still being considered, keeping the level lower than it should be.
 
Despite this increase in the CELOC, the areas requiring mitigation decreased only slightly. EPA’s model overestimates runoff, with some regions flagged at 45 ppb —numbers rarely seen in real world monitoring. This forces many ag retailers to adopt costly mitigation measures with little to no benefit to water quality. EPA should use real - world data rather than flawed modeling to estimate runoff.
 
For 60 years, atrazine has helped farmers increase yields, reduce soil erosion, and practice conservation tillage.  Please rely on sound science to keep this vital tool available. I appreciate EPA’s continued dialogue with ag retailers on this important issue.
 
Thank you
