 remains uncertain as litigation is ongoing.  At this time, DTE Gas does not expect a significant financial impact.As noted above for DTE Electric, the EPA finalized the NAAQS for fine particulate matter in March 2024.  It is likely that areas of Michigan in which DTE Gas operates will be designated as non-attainment in the future and the state will be required to develop a SIP for such areas.  However, the EPA has announced its intention to review the standard.  No impact is expected in the near term, and any long-term financial impacts cannot be assessed at this time.Non-utilityDTE Energy's non-utility businesses are subject to a number of environmental laws and regulations dealing with the protection of the environment from various pollutants.In March 2019, the EPA issued an FOV to EES Coke Battery, LLC ("EES Coke"), the Michigan coke battery facility that is a wholly-owned subsidiary of DTE Energy, alleging that the 2008 and 2014 permits issued by EGLE did not comply with the Clean Air Act.  In September 2020, the EPA issued another FOV alleging EES Coke's 2018 and 2019 SO2 emissions exceeded projections and hence violated non-attainment new source review permitting requirements.  EES Coke evaluated the EPA's alleged violations and believes that the permits approved by EGLE complied with the Clean Air Act.  EES Coke responded to the EPA's September 2020 allegations demonstrating its actual emissions are compliant with non-attainment new source review requirements.  On June 1, 2022, the U.S. Department of Justice ("DOJ"), on behalf of the EPA, filed a complaint against EES Coke in the U.S. District Court for the Eastern District of Michigan alleging that EES Coke failed to comply with non-attainment new source review requirements under the Clean Air Act when it applied for the 2014 permit.  In November 2022, the Sierra Club and City of River Rouge were granted intervention.  On May 20, 2024, the court granted a motion allowing the DOJ to amend their complaint to add EES Coke's parent entities, including DTE Energy, as defendants.  The parent entities were added in an attempt to share in any potential liability; there are no additional claims alleged.  Discovery has concluded and trial is set for September 2025.  At the present time, DTE Energy cannot predict the outcome or financial impact of this matter.
