"Dow Chemical is pushing a Trump administration open to scrapping regulations to ignore the findings of federal scientists who point to a family of widely used pesticides as harmful to about 1,800 critically threatened or endangered species. Lawyers representing Dow, whose CEO is a close adviser to Trump, and two other manufacturers of organophosphates sent letters last week to the heads of three of Trump's Cabinet agencies. The companies asked them "to set aside" the results of government studies the companies contend are fundamentally flawed. Dow Chemical wrote a $1 million check to help underwrite Trump's inaugural festivities, and its chairman and CEO, Andrew Liveris, heads a White House manufacturing working group. The industry's request comes after EPA Administrator Scott Pruitt announced last month he was reversing an Obama-era effort to bar the use of Dow's chlorpyrifos pesticide on food after recent peer-reviewed studies found that even tiny levels of exposure could hinder the development of children's brains. In his prior job as Oklahoma's attorney general, Pruitt often aligned himself in legal disputes with the interests of executives and corporations who supported his state campaigns. He filed more than a dozen lawsuits seeking to overturn some of the same regulations he is now charged with enforcing...Over the past four years, government scientists have compiled an official record running more than 10,000 pages indicating the three pesticides under review — chlorpyrifos, diazinon and malathion — pose a risk to nearly every endangered species they studied. Regulators at the three federal agencies, which share responsibilities for enforcing the Endangered Species Act, are close to issuing findings expected to result in new limits on how and where the highly toxic pesticides can be used...In a statement, the Dow subsidiary that sells chlorpyrifos said its lawyers asked for the EPA's biological assessment to be withdrawn because its "scientific basis was not reliable."...Environmental advocates said Wednesday that criticism of the government's scientists was unfounded. The methods used to conduct EPA's biological evaluations were developed by the National Academy of Sciences...Rachelle Schikorra, the director of public affairs for Dow Chemical, said any suggestion that the company's $1 million donation to Trump's inaugural committee was intended to help influence regulatory decisions is "completely off the mark." "Dow actively participates in policymaking and political processes, including political contributions to candidates, parties and causes, in compliance with all applicable federal and state laws," Schikorra said. "Dow maintains and is committed to the highest standard of ethical conduct in all such activity.""
