The EPA has recently provided additional information on its plans for regulating chlorpyrifos and is seeking comment. The entire article is at https://www.epa.gov/pesticides/updated-human-health-risk-analyses-chlorpyrifos

“EPA has revised the human health hazard assessment and drinking water exposure assessment for chlorpyrifos that supported our October 2015 proposal to revoke all food residue tolerances for chlorpyrifos. EPA has further analyzed watershed data from across the United States and characterized dietary exposure risk from drinking water residues in order to better understand the risk of chlorpyrifos exposure. EPA will make a final decision by March 31, 2017.”
