"One is a senior-level retiree from a power company that has battled stricter environmental regulations for decades. Two are industry consultants who helped co-author a 2015 paper questioning the approach that led EPA to tighten its national ozone standards later that year. A fourth, on the advisory board of a conservative nonprofit, questions evidence of the long-term health risks posed by exposure to fine particulates."
