Arizona GOP and Chamber of Commerce Sue EPA Over New PM 2.5 Pollution Standards

The lawsuit claims the new regulations are 'arbitrary, capricious, an abuse of discretion,' and will harm Arizona's economy.

Republican lawmakers in Arizona, alongside the state's Chamber of Commerce, have filed a lawsuit against the EPA's new PM 2.5 pollution standards, arguing they are harmful to the economy.
The new EPA rule aims to reduce PM 2.5 pollution levels, which are linked to serious health issues, from 12 to 9 micrograms per cubic meter.
Arizona's Senate President Warren Peterson criticized the rule as an 'unnecessary hardship' for businesses and claimed it would force jobs overseas.
The EPA estimates the rule will prevent 4,500 premature deaths and result in $46 billion in health benefits by 2032.
Critics argue the rule is unattainable and will drive up manufacturing costs, potentially leading to more offshoring of jobs.
