Environmental Protection Agency delays new ozone pollution standards until after the 2024 election

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.

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.

“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 letter cites “several issues” raised by the panel in a recent report that “warrant additional evaluation and review.”
