The EPA allowed pesticide giant Bayer to pick from a menu of regulation options for the controversial and destructive weedkiller dicamba, newly released agency documents show. The documents provide an unusually clear look into the process of developing pesticide regulations, which is typically done out of public view. It shows in detail how the EPA asked Bayer which regulations it wanted, received a response from Bayer, then put Bayer’s choices into a proposed federal rule. …Bayer chose the least protective for one regulation, and the middle of three levels of protection for another regulation. It also got one other change it requested into the rule. Pesticide regulations are typically a negotiation between industry and the EPA, but the exchange that the documents reveal is “crossing a line”, said Nathan Donley with the Center for Biological Diversity.
