FILE - In this Feb. 21, 2017, file photo, Environmental Protection Agency (EPA) Administrator Scott Pruitt speaks to employees of the EPA in Washington. Pruitt’s schedule shows he met with Dow CEO Andrew Liveris for about a half hour on March 9 during a conference held a Houston hotel. Twenty days later Pruitt announced his decision to deny a petition to ban Dow’s chlorpyrifos pesticide from being sprayed on food, despite a review by his agency’s own scientists that concluded ingesting even minuscule amounts of the chemical can interfere with the brain development of fetuses and infants. EPA released a copy of Pruitt’s March meeting schedule earlier this month following several Freedom of Information Act requests. (AP Photo/Susan Walsh, File)
This photo supplied by the Environmental Protection Agency shows oil trapped by a berm and siphon dam in a dry ravine where the oil from a Chevron spill was stopped March 7, 2017, near Rangely, Colo. Chevron Corp. says its crews are cleaning up about 4,800 gallons of oil that spilled from a failed pipeline into an intermittent stream on public land in northwestern Colorado. State officials said Tuesday, March 14, 2017, that the oil travelled about 2 miles downstream along an unnamed tributary of Stinking Water Creek in Rio Blanco County.
