The Environmental Protection Agency (EPA) will not seek to weaken regulations for ground-level ozone, a major respiratory irritant, the agency said in a court filing this week. The decision means the industry lawsuits will move forward at the D.C. Circuit, leaving the Trump DOJ to defend the ozone rules. Separately, environmental groups sued the EPA this week over its decision this year to not list some counties outside Chicago, Milwaukee and St. Louis as being in violation of the ozone rules.
