On Wednesday, a coalition of Republican-led states and industry groups filed three lawsuits contesting a recent US Environmental Protection Agency regulation strengthening air quality guidelines for soot pollution.
The lawsuits, filed in the US Circuit Court of Appeals for the D.C. Circuit, involve a range of industry organizations and 25 states, including Texas, Kentucky, and West Virginia.
Their objective is to halt the implementation of an EPA rule, finalized last month, that reduces the permissible average concentration of fine particulate matter, commonly known as soot, in the atmosphere.

In a statement, Kentucky Attorney General Russell Coleman, whose state collaborates with West Virginia in leading one of the lawsuits representing 24 states, expressed concerns that the standards would elevate expenses for manufacturers, utilities, and households.
“This rule will drive jobs and investment out of Kentucky and overseas, leaving employers and hardworking families to pay the price,” Coleman said in a statement.
The EPA’s regulation, devoid of a direct imposition of pollution controls on particular industries, bolstered the soot standards for the first time in more than ten years.
This action reduced the acceptable concentration of particulate matter smaller than 2.5 microns, known as PM 2.5, from 12 to 9 micrograms per cubic meter (µg/m3) on average.
