EPA plans to ignore thousands of deaths by changing its methods of risk assessment

The New York Times reports:

The Environmental Protection Agency plans to change the way it calculates the future health risks of air pollution, a shift that would predict thousands of fewer deaths and would help justify the planned rollback of a key climate change measure, according to five people with knowledge of the agency’s plans.

The proposed change would dramatically reduce the 1,400 additional premature deaths per year that the E.P.A. had initially forecast as a result of eliminating the old climate change regulation — the Clean Power Plan, which was President Barack Obama’s signature climate change measure. It would also make it easier for the administration to defend its replacement, known as the Affordable Clean Energy rule.

It has been a constant struggle for the E.P.A. to demonstrate, as it is normally expected to do, that society will see more benefits than costs from major regulatory changes. This is one of many examples of the Trump administration downgrading the estimates of environmental harm from pollution in regulations.

The new modeling method, which experts said has never been peer-reviewed and is not scientifically sound, would most likely be used by the Trump administration to defend further rollbacks of air pollution rules if it is formally adopted. But the proposed change is unusual because it relies on unfounded medical assumptions and discards more than a decade of peer-reviewed E.P.A. methods for understanding the health hazards linked to the fine particulate matter produced by burning fossil fuels.
