Ohio counties must cut air pollution from factories and power plants
What happened
US environmental regulators are proposing to approve Ohio's plan to reduce ozone-forming pollution in the Cleveland area. This means industrial facilities in seven Ohio counties will need to use updated pollution control technology.
Why it matters
The US environmental regulators set national air quality standards, but states must create and enforce plans to meet them. This approval means Ohio's plan for the Cleveland area is now officially part of the federal enforcement system. Companies in these counties will face new requirements to install or upgrade equipment to reduce emissions.
The signal
Watch for public comments on this proposed rule, and then for the final approval, which will trigger the compliance clock for affected facilities.
