It’s a seismic shift that runs counter to the E.P.A.’s mission statement, which says the agency’s core responsibility is to protect human health and the environment, environmental law experts said. The change could make it easier to repeal limits on these pollutants from coal-burning power plants, oil refineries, steel mills and other industrial facilities across the country, the emails and documents show. That would most likely lower costs for companies while resulting in dirtier air. “The idea that E.P.A. would not consider the public health benefits of its regulations is anathema to the very mission of E.P.A.,” said Richard Revesz, the faculty director of the Institute for Policy Integrity at New York University School of Law.
“If you’re only considering the costs to industry and you’re ignoring the benefits, then you can’t justify any regulations that protect public health, which is the very reason that E.P.A. was set up.”
