U.S. makers dispute pesticides’ risks to endangered species
Manufacturers of three organophosphate insecticides are urging EPA to abandon its process for assessing the risks of pesticides on endangered species. The companies—Dow AgroSciences, Makhteshim Agan of North America (Adama), and FMC Corp.—claim that EPA’s approach is fundamentally flawed. At issue are biological evaluations of three pesticides—chlorpyrifos, diazinon, and malathion—released by EPA in the final days of the Obama Administration. The evaluations conclude that the three chemicals are likely to adversely affect more than 1,000 endangered species. The three companies claim that EPA failed to adequately describe its risk assessment approach, making it difficult to evaluate and reproduce the results. The companies are also questioning EPA’s use of studies that were not evaluated for data quality and relevance and why the agency failed to consider several studies submitted by the pesticide industry. In addition, the companies say that EPA’s estimates for exposure to the pesticides are “unrealistically high and sometimes physically impossible.” The Center for Biological Diversity, an environmental group, says that Dow is profiting by pressuring the Trump Administration to scrap efforts to regulate pesticides.
