States push for coal ash control as federal oversight weakens

State governments with close coal industry ties are moving to take over coal ash regulation from the federal government, raising concerns that toxic waste will be left with little oversight for years to come.

Kari Lydersen reports for Canary Media.


In short:

  • The Trump administration’s EPA is encouraging states like Indiana to take over regulation of coal ash, a toxic byproduct of coal-fired power, through “primacy” arrangements that can lock in weaker enforcement even under future administrations.
  • Indiana lawmakers have already passed laws requiring the state to seek primacy, despite widespread groundwater contamination from more than 73 million cubic yards of coal ash stored in unlined ponds.
  • Environmental advocates warn that once states gain primacy, it becomes difficult for federal authorities to reassert control, even if national rules are later strengthened.

Key quote:

“The Trump administration is a four-year term, and managing coal ash is going to be decades into the future. This is a long-term issue that requires federal oversight for the duration; it’s absolutely critical the federal government keep that ability.”

— Ben Inskeep, program director, Citizens Action Coalition

Why this matters:

Coal ash is one of the largest sources of industrial waste in the U.S., and it contains hazardous substances like arsenic, mercury, and lead. When stored in unlined ponds — as is common in states like Indiana — it can seep into groundwater and contaminate drinking supplies. Many of the worst sites are located near low-income or rural communities that have limited access to clean water and face greater barriers to holding polluters accountable. Allowing states with weak environmental records to self-regulate coal ash increases the risk that toxic waste will go unmonitored and unremedied for decades.
