later than 31 October 2015. The EPA was "unable to conclude that the risk from aggregate exposure from the use of chlorpyrifos [met] the safety standard of section 408(b)(2) of the Federal Food, Drug, and Cosmetic Act (FFDCA)" and therefore proposed "to revoke all tolerances for chlorpyrifos." In an 30 October 2015 statement Dow AgroSciences disagreed with the EPA's proposed revocation and "remain[ed] confident that authorized uses of chlorpyrifos products, as directed, offer wide margins of protection for human health and safety." In a November 2016 press release, DOW argued that chlorpyrifos was "a critical tool for growers of more than 50 different types of crops in the United States" with limited or no viable alternatives." The Environment News Service quoted the Dow AgroSciences' statement disagreeing with the EPA findings. In November 2016, the EPA reassessed its ban proposal after taking into consideration recommendations made by the agency's Science Advisory Panel which had rejected the EPA's methodology in quantifying the risk posed by chlorpyrifos. Using a different methodology as suggested by the panel, the EPA retained its decision to completely ban chlorpyrifos. The EPA concluded that, while "uncertainties" remain, a number of studies provide "sufficient evidence" that children experience neurodevelopment effects even at low levels of chlorpyrifos exposure. On 29 March 2017, EPA Administrator Scott Pruitt, appointed by the Trump administration, overturned the 2015 EPA revocation and denied the administrative petition by the Natural Resources Defense Council and the Pesticide Action Network North America to ban chlorpyrifos. The American Academy of Pediatrics responded to the administration's decision saying they are "deeply alarmed" by Pruitt's decision to allow the pesticide's continued use. "There is a wealth of science demonstrating the detrimental effects of chlorpyrifos exposure to developing fetuses, infants, children and pregnant women. The risk to infant and children's health and development is unambiguous." Asked in April whether Pruitt had met with Dow Chemical Company executives or lobbyists before his decision, an EPA spokesman replied: "We have had no meetings with Dow on this topic." In June, after several Freedom of Information Act requests, the EPA released a copy of Pruitt's March meeting schedule which showed that a meeting had been scheduled between Pruitt and Dow CEO Andrew Liveris at a hotel in Houston, Texas, on 9 March. Both men were featured speakers at an energy conference. An EPA spokesperson reported that the meeting was brief and the pesticide was not
