CMS ENERGY CORP 10-Q form for quarterly period ended 2024-03-31, page 34: MPSC Distribution System Audit: In 2022, the MPSC ordered the state's two largest electric utilities, including Consumers, to report on their compliance with regulations and past MPSC orders governing the utilities' response to outages and downed lines. Consumers responded to the MPSC's order as directed. 
Additionally, as directed by the MPSC, the MPSC Staff has engaged a third‑party auditor to review all equipment and operations of the two utilities' distribution systems; this audit began in August 2023. The MPSC Staff released a report prepared by the third-party auditor to summarize the audit's progress in December 2023, and a final report is expected in late summer 2024. Consumers is committed to working with the third‑party auditor and the MPSC to continue improving electric reliability and safety in Michigan.
Retention Incentive Program: Under its Clean Energy Plan, Consumers will retire the J.H. Campbell coal-fueled generating units in 2025. In order to ensure necessary staffing at J.H. Campbell through retirement, Consumers has implemented a retention incentive program. The aggregate cost of the J.H. Campbell program through 2025 is estimated to be $50 million; Consumers expects to recognize $10 million of retention benefit costs in 2024. The MPSC has approved deferred accounting treatment for these costs; these expenses are deferred as a regulatory asset. For additional details on this program, see Notes to the Unaudited Consolidated Financial Statements-Note 12, Exit Activities.
Electric Environmental Outlook: Consumers' electric operations are subject to various federal, state, and local environmental laws and regulations. Consumers estimates that it will incur capital expenditures of $240 million from 2024 through 2028 to continue to comply with RCRA, the Clean Air Act, and numerous other environmental regulations. Consumers expects to recover these costs in customer rates, but cannot guarantee this result. Multiple environmental laws and regulations are subject to litigation. Consumers' primary environmental compliance focus includes, but is not limited to, the following matters.
Air Quality: Multiple air quality regulations apply, or may apply, to Consumers' electric utility.
MATS, emission standards for electric generating units published by the EPA based on Section 112 of the Clean Air Act, continue to apply to Consumers. The company has complied, and continues to comply, with the MATS regulation and does not expect MATS to materially impact its environmental strategy.
CSAPR requires Michigan and many other states to improve air quality by reducing power plant emissions that, according to EPA modeling, contribute to ground-level ozone in other downwind states. Since its 2015 effective date, CSAPR has been revised several times. In June 2023, the EPA published the Good Neighbor Plan, a revision to CSAPR. This regulation tightens allowance budgets for electric generating units in Michigan between 2023 and 2029 and changes the mechanism for allocating such allowances on a year-over-year basis beginning in 2026. Consumers' initial evaluation of this regulation indicates that it will have minimal financial and operational impact in the near term. Additionally, Consumers does not expect any major financial and operational impact in the long term. However, due to the dynamic nature of this regulation, it is difficult to forecast the long-term impact.
In 2015, the EPA lowered the NAAQS for ozone and made it more difficult to construct or modify power plants and other emission sources in areas of the country that do not meet the ozone standard. As of May 2023, three counties in western Michigan have been designated as not meeting the ozone standard. None of Consumers' fossil-fuel-fired generating units are located in these areas. 
Additionally, in March 2024, the EPA published a lower fine particulate matter NAAQS, which will likely result in newly designated nonattainment areas in Michigan starting in 2026. Consumers does not expect this rule to have significant impacts on its fossil-fuel-fired generating assets or its clean energy

Consumers continues to evaluate these rules in conjunction with other EPA and EGLE rulemakings, litigation, executive orders, treaties, and congressional actions. This evaluation could result in:
•a change in Consumers' fuel mix
•changes in the types of generating units Consumers may purchase or build in the future
•changes in how certain units are operated, including the installation of additional emission control equipment
•the retirement, mothballing, or repowering with an alternative fuel of some of Consumers' generating units
•changes in Consumers' environmental compliance costs
•the purchase or sale of allowances
Greenhouse Gases: There have been numerous legislative and regulatory initiatives at the state, regional, national, and international levels that involve the potential regulation and reporting of greenhouse gases. Consumers continues to monitor and comment on these initiatives, as appropriate.
In May 2023, the EPA released its proposed rule to address greenhouse gas emissions from existing fossil-fuel-fired electric generating units. Under its Clean Energy Plan, Consumers will eliminate the use of coal-fueled generation in 2025. Therefore, this proposed rule will not materially impact Consumers over the remaining operating lives of these coal-fueled facilities. The proposed rule had requirements for existing natural gas-fueled facilities that could have had a material impact on Consumers' natural gas-fueled facilities. However, the EPA announced in March 2024 that the final rule, expected in April or May 2024, will not cover existing natural gas-fueled facilities. Instead, the EPA expects to cover those facilities in a future rulemaking. Consumers will continue to follow the finalization of this rule and any subsequent rules to control greenhouse gases and will continue to evaluate potential impacts to its Clean Energy Plan.
Under the Paris Agreement, an international agreement addressing greenhouse gas emissions, the U.S. has committed to reduce greenhouse gas emissions by 50 to 52 percent from 2005 levels by 2030. Under its Clean Energy Plan, Consumers plans to reduce carbon emissions from its electric business by 60 percent from 2005 levels in 2025. At this time, Consumers does not expect any adverse changes to its environmental strategy as a result of this event, as its plans exceed the nationally committed reduction. The commitment made by the U.S. is not binding without new Congressional legislation.
In 2020, Michigan's Governor signed an executive order creating the Michigan Healthy Climate Plan, which outlines goals for Michigan to achieve economy-wide net-zero greenhouse gas emissions and to be carbon neutral by 2050. The executive order aims for a 28‑percent reduction below 2005 levels of greenhouse gas emissions by 2025. Consumers has already surpassed the 28‑percent reduction milestone for its owned electric generation and previously announced a goal of achieving net-zero carbon emissions from its electric business by 2040. The 2023 Energy Law codifies much of the Governor's goals. For additional details on the 2023 Energy Law, see the Planet section of the Executive Overview. 
Increased frequency or intensity of severe or extreme weather events, including those due to climate change, could materially impact Consumers' facilities, energy sales, and results of operations. Consumers is unable to predict these events; however, Consumers evaluates the potential physical impacts of climate change on its operations, including increased frequency or intensity of storm activity; increased precipitation; increased temperature; and changes in lake and river levels. Consumers released a report addressing the physical risks of climate change on its infrastructure in 2022. Consumers is taking steps to mitigate these risks as appropriate.

, CMS ENERGY CORP 10-Q form for quarterly period ended 2024-03-31, page 36: While Consumers cannot predict the outcome of changes in U.S. policy or of other legislative, executive, or regulatory initiatives involving the potential regulation or reporting of greenhouse gases, it intends to move forward with its Clean Energy Plan, its present net-zero goals, and its emphasis on reliable and resilient supply. Litigation, international treaties, executive orders, federal laws and regulations (including regulations by the EPA), and state laws and regulations, if enacted or ratified, could ultimately impact Consumers. Consumers may be required to:
•replace equipment
•install additional emission control equipment
•purchase emission allowances or credits (including potential greenhouse gas offset credits)
•curtail operations
•arrange for alternative sources of supply
•purchase or build facilities that generate fewer emissions
•mothball, sell, or retire facilities that generate certain emissions
•pursue energy efficiency or demand response measures more swiftly
•take other steps to manage, sequester, or lower the emission of greenhouse gases
Although associated capital or operating costs relating to greenhouse gas regulation or legislation could be material and cost recovery cannot be assured, Consumers expects to recover these costs in rates consistent with the recovery of other reasonable costs of complying with environmental laws and regulations.
CCRs: In 2015, the EPA published a rule regulating CCRs under RCRA. This rule adopts minimum standards for the disposal of non‑hazardous CCRs in CCR landfills and surface impoundments and criteria for the beneficial use of CCRs. The rule also sets out conditions under which some CCR units would be forced to cease receiving CCR wastewater and initiate closure. Due to continued litigation, many aspects of the rule have been remanded to the EPA, resulting in more proposed and final rules.
Separately, Congress passed legislation in 2016 allowing participating states to develop permitting programs for CCRs under RCRA Subtitle D. The EPA was granted authority to review these permitting programs to determine if permits issued under the proposed program would be as protective as the federal rule. Once approved, permits issued from an authorized state would replace the requirement to certify compliance with each aspect of the CCR rule. In 2020, EGLE submitted a regulatory package for Michigan's permit program to the EPA for its review, which is still pending.
Consumers, with agreement from EGLE, completed the work necessary to initiate closure by excavating CCRs or placing a final cover over each of its relevant CCR units prior to the closure initiation deadline. Consumers has historically been authorized to recover in electric rates costs related to coal ash disposal sites.
Water: Multiple water-related regulations apply, or may apply, to Consumers.
The EPA regulates cooling water intake systems of existing electric generating plants under Section 316(b) of the Clean Water Act. The rules seek to reduce alleged harmful impacts on aquatic organisms, such as fish. In 2018, Consumers submitted to EGLE for approval all required studies and recommended plans to comply with Section 316(b) for its coal-fueled units, but has not yet received final approval.
The EPA also regulates the discharge of wastewater through its effluent limitation guidelines for steam electric generating plants. In 2020, the EPA revised previous guidelines related to the discharge of certain wastewater, but allowed for extension of the compliance deadline from the end of 2023 to the end of 2025, upon approval by EGLE through the NPDES permitting process. Consumers received such an

Question: What are CMS Energy Corp.'s key priorities in environmental compliance for the quarter ended March 31, 2024?
Answer: Consumers Energy prioritizes environmental compliance across several critical areas to align with federal, state, and local regulations. A key focus is on air quality, where the company complies with standards like the Mercury and Air Toxics Standards (MATS) and the Cross-State Air Pollution Rule (CSAPR), including its recent Good Neighbor Plan revisions. While these regulations tighten emission allowances, Consumers anticipates minimal near-term impacts. In greenhouse gas management, the company is on track to eliminate coal-fueled generation by 2025, supporting its goal of net-zero carbon emissions by 2040. It aligns with Michigan’s Healthy Climate Plan, which aims for carbon neutrality by 2050.
Consumers also addresses coal combustion residuals (CCR) through compliance with EPA regulations, working with Michigan’s EGLE to ensure safe closure of CCR units. Water compliance remains a priority, particularly under the Clean Water Act, where the company focuses on reducing impacts from cooling water intake systems and meeting effluent limitation guidelines for wastewater discharge. Additionally, Consumers actively complies with wildlife protection laws such as the Endangered Species Act and the Migratory Bird Treaty Act, ensuring minimal impact on protected species during the operation of renewable energy projects.
These efforts are supported by $240 million in planned capital expenditures from 2024 through 2028, which Consumers expects to recover in customer rates, ensuring both compliance and financial sustainability.
