EPA Releases Draft Triazine Ecological Risk Assessments for Comment
Originally released June 2, 2016
- June 6, 2016 to reflect the start of the comment period.
- July 7, 2016, to reflect comment period extension.
EPA is releasing the draft ecological risk assessments for atrazine, propazine and simazine, which evaluate risks to animals and plants including, amphibians, birds, mammals, fish, reptiles, aquatic invertebrates, aquatic plant communities, and terrestrial plants. All three pesticides are in the triazine class of pesticides.
EPA invites stakeholders to comment on the draft ecological risk assessments. The draft assessments are currently available on the agency's website. EPA will be accepting public comments until October 4, 2016 (extended from the original closing date of August 5). After receiving and reviewing public comments, the agency will amend the assessments, as appropriate. EPA will have atrazine's assessment peer reviewed by the Scientific Advisory Panel in 2017.
With regard to atrazine, the herbicide is one of the most widely used agricultural pesticides in the United States. It is used primarily on corn and sorghum in the Midwest and sugarcane in the South Central and Southeastern United States to control broadleaf and grassy weeds.
EPA's human health assessment for the three triazines is currently under review, and we expect to release it later in 2016.
Read the triazine draft ecological risk assessments on EPA's website. On this page, you will find links to the Federal Register notice and the dockets. The assessments and all related materials are available and comments can be submitted at www.regulations.gov in dockets EPA-HQ-OPP-2013-0266 (atrazine); EPA-HQ-OPP-2013-0250 (propazine); and EPA-HQ-OPP-2013-0251 (simazine).
