When the U.S. government shut down in late 2018, it furloughed nearly 600 Environmental Protection Agency pollution inspectors for more than a month. Those workers had to stop their work of monitoring and inspecting industrial sites for pollution, and stopped enforcing environmental-protection laws, including the Clean Air Act.
My colleagues and I analyzed six years’ worth of air quality levels, emissions measurements, power production data and weather reports for more than 200 coal-fired power plants around the country. We found that the coal plants’ operators appeared to take advantage of the lapse in enforcement of environmental regulations.
