Ignoring Scientists’ Advice, Trump’s EPA Rejects Stricter Air Quality Standard

preview

The proposal to maintain the current standard for PM 2.5—microscopic particles known as fine particulate matter—in the face of alarming new science documenting its potentially deadly health effects, is a win for the fossil fuel industry. It comes amid a frenzy of major decision-making at the Environmental Protection Agency that critics say is designed to secure the Trump administration's pro-industry legacy in the face of an uncertain future. could be summarily reversed by the next Congress if Democrats were to retake the White House and Senate in November's election. It's not clear if the PM 2.5 decision will make the deadline—there will be a 60-day public comment period after the plan is published in the Federal Register.Sign up forOur stories. Your inbox.

But he also decided to give little weight to eight large epidemiological studies published over the last seven years, all of which were peer-reviewed and indicated that the current PM 2.5 standard was inadequate. t that recommended a stronger standard, which they calculated it would save lives. One of the studies the assessment relied upon was of 60 million Americans; it showed that lowering the level of PM 2.5 pollution nationwide by just 1 microgram per cubic meter would save 12,000 American lives annually. The current national standard of 12 micrograms per cubic meter was adopted by the Obama administration in 2012. EPA's scientists said that a decision to keep that standard "would place little weight on the broad body of epidemiologic evidence" showing "statistically significant" health effects at that level. "This administration is passing up an opportunity to make the air cleaner for millions of Americans—choosing instead to do nothing," said Gina McCarthy, who served as Obama's EPA administrator and is now president and CEO of the Natural Resources Defense Council, in a statement. "That's indefensible—especially amid a health crisis that is hitting people who live in communities with high levels of air pollution the hardest."Under the Clean Air Act, the EPA is required to continually review the science on several common pollutants to ensure that National Ambient Air Quality Standards keep up with what is known about their health effects. Wheeler noted that his decision on PM 2.5 marked the first time the EPA had ever met the goal of finishing such a review within five years, as the law requires. His speed won him no plaudits in the environmental community."This dismissal of the latest scientific knowledge is unconscionable, and patently ignores the overarching statutory requirement to promote public health," said Hayden Hashimoto, attorney for the Clean Air Task Force.since Trump took office. The number of "unhealthy air days" in major cities, based on both smog and PM 2.5 levels, rose to its highest level since 2012. Wheeler said that the science on the benefits of stronger PM 2.5 standards was too uncertain to justify tighter regulation, citing the advice that he had received from his hand-picked committee of scientific advisers, including a number of industry-allied scientists. after failing to reach consensus on the adequacy of the current PM 2.5 standard.The EPA circulated comments from Republican members of Congress and state officials praising the decision to maintain the current PM 2.5 standard. "With several announcements over the past few weeks the Trump administration and the EPA administration continue to demonstrate that states have rights and, more importantly, that science will be the guiding light when it comes to regulating the environment," said Austin Caperton, secretary of West Virginia's Department of Environmental Protection, under Republican governor Jim Justice, a former coal mining executive. But environmental and health advocates who have watched the PM 2.5 review unfold over the course of the last three years were sharply critical of both the process and results. At the same time that Wheeler was making his announcement on Tuesday, the Union of Concerned Scientists hosted an extraordinary "shadow hearing" to focus  on a separate, but related EPA action—a plan to restrict the use of science at the agency. The proposed rule, called "Strengthening Transparency in Regulatory Science," would restrict the EPA's use of certain epidemiological studies in its decision-making, including some of the most important studies on the dangers of PM 2.5. If approved, the rule could make it difficult for the EPA to strengthen PM 2.5 standards after Trump leaves office.With a May 18 public comment deadline looming on the proposal, and the EPA refusing to hold a hearing on its recent revision and expansion of the plan, the Union of Concerned Scientists' conducted its hearing using the online service Zoom and had more than 100 people signed up to speak."What EPA does depends on the confidence of the public, it depends on the integrity of the scientific basis for its decision-making," said William Reilly, who served as EPA administrator during President George H.W. Bush's administration and one of those who spoke during the video conference call. He added, "Both have been put into question by the current proposed regulation." national senior vice president for public policy at the American Lung Association, also spoke, arguing that the proposal would be harmful for public health and should be withdrawn."Every day the news reminds us of how important lung health is for us," Billings said.  "Make no mistake: This is not an effort to strengthen transparency or improve regulatory science. The proposal is an effort to exclude important studies whose conclusions, especially that particulate air pollution causes premature death, are inconvenient."Published Under:Our stories. Your inbox.
