  The EPA recently announced their desire to revise the CCR regulations, but at this time the effective date and extent of any revisions are unknown.  The current cost estimate to comply with the revised rule is approximately $430 million as of September 30, 2025, and is recorded to Asset retirement obligations.  The estimate was increased by $130 million in the third quarter of 2025 based on findings from more thorough site investigations.  The estimate will continue to be updated as necessary when site-specific details are more fully known.  These costs are expected to be recoverable under the regulatory construct as part of removal costs.At the state level, legislation was signed in December 2018 and provides for further regulation of the CCR program in Michigan.  Additionally, the statutory revision provides the basis of a CCR program that EGLE has submitted to the EPA for approval to fully regulate the CCR program in Michigan in lieu of a federal permit program.  The EPA is currently working with EGLE in reviewing the submitted state program, and DTE Electric will work with EGLE to implement the state program that may be approved in the future.The EPA updated and revised the ELG in 2015, 2020, and 2024.  In each revision, EPA has re-established technology-based standards applicable to wastewaters created at facilities with an electrical generating unit.  In each revision, the EPA also established new applicability dates.The Reconsideration Rule, finalized in 2020, provided additional opportunities by finalizing a group of compliance subcategories that provided cessation of coal as a compliance option.  Additionally, the 2020 Reconsideration Rule established the Voluntary Incentives Program (VIP) for FGD wastewater compliance only.  If a facility applies for the VIP, they must meet more stringent standards, but are allowed an extended time period to meet the compliance requirements by December 1, 2028.  The Reconsideration Rule provided these new opportunities for DTE Electric to evaluate existing ELG compliance strategies and make any necessary adjustments to ensure full compliance with the ELGs in a cost-effective manner.
