Indiana Coal Ash Primacy: What the 180-Day Permit Clock Means for Your Utility Bill

EPA Deputy Administrator David Fotouhi visited Indiana this week to announce the Trump administration's proposal to give IDEM primacy over coal combustion residuals permitting: all 100 CCR units at facilities operated by Duke Energy Indiana, AES Indiana, NIPSCO, and CenterPoint Energy, among others. Governor Braun and Fotouhi framed it as regulatory certainty and lower energy costs. Indra Frank of the Hoosier Environmental Council acknowledged the current federal rule is in good shape but flagged the critical risk: a 2023 Indiana law caps state CCR rules at the federal floor, meaning any federal rollback, which the Trump EPA is actively pursuing, automatically becomes Indiana's ceiling.

The mechanism most directly relevant to you as an industrial power customer: once IDEM's program receives final approval, all 100 units have 180 days to submit permit applications simultaneously, a permitting surge IDEM must process under resource constraints. On rate recovery, the Citizens Action Coalition already successfully blocked Duke Energy from charging ratepayers $65 million in unauthorized coal ash cleanup costs. But CAC and other intervenors have flagged concern that IDEM-permitted compliance pathways could be characterized by utilities as prudent, permitted expenditures, a framing IURC has previously rejected but may revisit under the new state framework.

If your utility pursues that argument in the next rate case, you absorb it directly in your industrial power tariff. Engage with active intervenors in IURC proceedings now, before those docket filings land.
