As a result of a March 2006 settlement with the Natural Resources Defense Council, EPA is making data available regarding the potential effects of atrazine, a pesticide ingredient, to eight threatened and endangered species in 40 potentially vulnerable watersheds.
In its October 2003 determination that products containing atrazine were eligible for reregistration, EPA required the atrazine registrants, among other things, to undertake an intensive watershed monitoring program to further verify the determination that use of this herbicide was not likely to cause unreasonable risk to freshwater resources. One component of the monitoring program is focused on flowing water bodies, and provides two years of monitoring data, accrued over a three-year period (2004-2006), in 40 potentially vulnerable watersheds associated with corn and sorghum production.
EPA is in the process of assessing the potential effects of atrazine use to the eight threatened and endangered species identified in the Settlement Agreement and will complete that assessment by February 28, 2007. Therefore, on January 29, 2007, EPA made available on its Web site a fact sheet announcing the availability of the watershed monitoring results for the herbicide atrazine in 40 potentially vulnerable watersheds.
The atrazine watershed monitoring data may be obtained through a Freedom of Information Act request after completion and submission of an Affirmation of Non-multinational Status Form, pursuant to FIFRA Section 10(g). For more information on Freedom of Information Act requests, please visit the Freedom of Information Act website at foia.state.gov. When requesting these data, you should request the "Atrazine Ecological Watershed Monitoring Data".
