ACTION NEEDED: EPA Re-Opening Atrazine Registration - Comment Period Open Until September 6.

Recently, EPA announced it has re-evaluated the current atrazine level of concern (LOC), which is 15 ppb, and “determined” in its proposed revised interim registration review decision (IRRD) that the LOC is 3.4 ppb with additional label mitigation measures required for atrazine use. EPA then issued a notice announcing a public comment period of 60 days ending on September 6, 2022.
In its announcement, EPA stated: “After considering comments on the proposed revisions to the atrazine ID, EPA will determine if any changes are warranted to the proposed revisions and then release its decision on this re-evaluation. The Agency also intends to seek external peer review of the risks to the aquatic plant community that underlies this proposed risk management strategy.”
Atrazine is a vital tool for farmers across Illinois and the nation, and it is especially important to farmers who implement conservation tillage, or no-till farming, which plays a significant role in carbon sequestration. An LOC of 3.4 ppb would impact over 65 million acres of corn and sorghum acres (over 70% of all corn acres).
Click Here to submit comments urging EPA to be more fully transparent in promptly making available, to the public, all relevant data and its rationale for adopting an atrazine LOC of 3.4 ppb, using its WARP-MP model, and requiring additional label mitigation measures.
The Illinois Fertilizer and Chemical Association will file comments on EPA’s review of Atrazine registration.  We will keep our members informed if we get any additional information.  If you have further questions, please don’t hesitate to reach out to KJ Johnson at 217-369-1669 or
