February 5, 2018 โ For months, chemical companies have waged a campaign to reverse findings by federal fisheries scientists that could curb the use of pesticides based on the threat they pose to endangered species. They scored a major victory this week, when Environmental Protection Agency Administrator Scott Pruitt announced he would press another federal agency to revisit a recent opinion triggering such restrictions.
The struggle over an arcane provision of the Endangered Species Act, in which the EPA must affirm that the pesticides it oversees do not put speciesโ survival in jeopardy, has become the latest front in the battle over a broad-spectrum insecticide known as chlorpyrifos. Pruitt denied a petition to ban its agricultural use after questioning EPA scientistsโ conclusions that exposure impedes brain development in infants and fetuses.
Speaking to the National Association of State Departments of Agriculture on Wednesday, Pruitt said he plans to inform the National Oceanic and Atmospheric Administrationโs Marine Fisheries Service โthat there needs to be a consultation because we have usage data, frankly, that wasnโt considered.โ
NOAA Fisheries issued a Biological Opinion on Dec. 29, which was publicly released Jan. 9 by the environmental law firm Earthjustice, finding that the current use of chlorpyrifos and malathion โis likely to jeopardize the continued existenceโ of 38 species of salmon and other fish in the Pacific Northwest and destroy or harm the designated critical habitat of 37 of those species. It found another pesticide, diazinon, could jeopardize the continued existence of 25 listed fish species and could harm critical habitat for 18 of them.
In allowing chlorpyrifos to stay on the market โ the product is already prohibited for household products โ Pruitt cited concerns raised by the Department of Agriculture, pesticide industry groups and an EPA scientific review panel about studies the agency used to conclude that the pesticide poses a serious enough neurological risk to ban its use on dozens of crops. One study, by researchers at Columbia University, found a connection between higher exposure levels to chlorpyrifos and learning and memory problems among farmworkers and children.
