An increased number of asthma attacks, sick days and even premature death are likely to occur, he and other public health advocates said.

The problem is particularly acute in urban areas.īillings called the ozone rule “the public health cornerstone of the Clean Air Act,” adding that “millions of people will breathe dirty air for many more years” as a result of the delay. A recent report by the lung association showed that minority communities bear a disproportionate burden from ground-level ozone, which occurs when air pollution from cars, power plants and other sources mixes with sunlight. Paul Billings, senior vice president of the American Lung Association, called the EPA’s decision “profoundly disappointing” and a missed opportunity to protect public health and promote environmental justice. President Barack Obama shut down plans to tighten ozone standards in 2011, leading to a four-year delay before the standards were updated in 2015. The delay marks the second time in 12 years that a Democratic administration has put off a new ozone standard prior to an election year. Regan’s decision avoids an election-year battle with industry groups and Republicans who have complained about what they consider overly intrusive EPA rules on power plants, refineries, automobiles and other polluters. The review, which will last at least two years, will “ensure that air quality standards reflect the latest science in order to best protect people from pollution,” Regan said. The letter cites “several issues” raised by the panel in a recent report that “warrant additional evaluation and review.” “I have decided that the best path forward is to initiate a new statutory review of the ozone (standard) and the underlying air quality criteria,” Regan wrote in a letter to the EPA advisory panel last month. The decision by EPA Administrator Michael Regan means that one of the agency’s most important air quality regulations will not be updated until well after the 2024 presidential election. WASHINGTON > The Environmental Protection Agency is delaying plans to tighten air quality standards for ground-level ozone - better known as smog - despite a recommendation by a scientific advisory panel to lower air pollution limits to protect public health.
