Key Takeaways
- Federal environmental law currently lacks a general rule that deems cumulative environmental burdens unlawful; harm is only actionable when tied to a separate statutory violation.
- Executive Order 12898 (1994) required agencies to identify and address disproportionate impacts on minority and low‑income populations, but its revocation in 2025 removed the government‑wide directive that forced consideration of cumulative effects.
- The xAI Southaven data‑center case illustrates how individual permits can be satisfied while the combined emissions from natural‑gas turbines, highways, and warehouses impose an unacceptable cumulative burden on already overburdened communities.
- Local governments can sometimes block harmful projects directly (e.g., Monterey Park’s voter‑approved Measure NDC), a power that federal law generally does not grant to communities.
- Under the Federal Power Act, FERC has a statutory duty to ensure “just and reasonable” rates and can require large‑load customers such as data centers to internalize their cost‑shifting burdens, even if executive orders push for deregulation.
- The Toxic Substances Control Act (TSCA) already covers the fluorinated coolants, flame retardants, and battery electrolytes used in data centers, but the EPA has not yet exercised its authority to regulate their disposal or use.
Historical Roots of Environmental‑Justice Law
Section I begins by documenting a long‑standing pattern: polluting infrastructure has been sited in minority neighborhoods because of residential segregation and government disinvestment. A 1979 Houston study found that all five city‑owned landfills and six of eight incinerators lay in Black neighborhoods, and three years later North Carolina dumped 40,000 cubic yards of PCB‑contaminated soil in the predominantly Black, 25 %‑poor community of Afton despite legal challenges and protests. These episodes helped spur the federal government to examine racial disparities in hazardous‑waste siting, culminating in President Bill Clinton’s Executive Order 12898 in 1994, which directed agencies to identify and address “disproportionately high and adverse” environmental and health effects on minority and low‑income populations. Although individuals could not sue solely for violating the Order, it supplied a government‑wide framework for weaving environmental justice into existing statutory authority.
Revocation and the Rise of AI Infrastructure
President Donald Trump revoked EO 12898 on January 21, 2025 through Executive Order 14173, leaving the underlying environmental statutes intact but removing the directive that forced agencies to consider cumulative impacts. The revocation coincided with a federal push to accelerate artificial‑intelligence (AI) data‑center construction. As the article notes, “Data centers may satisfy individual environmental requirements while adding emissions, noise, water depletion, and public‑health risks to already overburdened communities.” Without EO 12898, the question of cumulative impact no longer has a guaranteed place in the federal process, leaving communities with a right to be heard but not a meaningful right to refuse additional burdens.
The xAI Southaven Case: Permitting vs. Cumulative Harm
The article highlights xAI’s $20 billion Southaven data center in Mississippi, described by Governor Tate Reeves as “the largest economic development project in Mississippi’s history.” xAI, through subsidiary MZX Tech, installed twenty‑seven natural‑gas turbines near homes, schools, and churches. The Mississippi Department of Environmental Quality (MDEQ) deemed the turbines “portable” and therefore exempt from Clean Air Act (CAA) permitting because they were intended to remain on site for fewer than twelve months. In April 2026 the NAACP filed a CAA citizen suit (Section 304, 42 U.S.C. § 7604) alleging that xAI constructed and operated the turbines without any applicable construction or operating permit. The complaint invokes three permitting regimes: (1) construction of a “major stationary source” without Prevention of Significant Deterioration (PSD) review; (2) potential nitrogen‑oxide emissions exceeding major‑source thresholds requiring a Title V operating permit; and (3) violations of federal Hazardous Air Pollutant (HAP) standards, citing unpermitted emissions of carcinogens such as formaldehyde. Even if the turbines obtained all required permits, the article stresses that “valid permit establishes compliance with the conditions governing that source, not that adding its emissions to pollution from nearby highways, warehouses, or industrial sources is acceptable for the surrounding community.” Federal law contains no general cumulative‑burden threshold that would compel regulators to reject a project simply because its added pollution would impose an unacceptable combined burden on an already overburdened area.
Why Existing Federal Laws Fall Short on Cumulative Harm
NEPA offers only procedural safeguards: it requires federal agencies to evaluate environmental effects of major federal actions but does not compel them to choose the least harmful alternative. As Robertson v. Methow Valley Citizens Council (1989) held, agencies must take a “hard look” at consequences but may still approve a project that worsens pollution. Title VI of the Civil Rights Act prohibits discrimination in federally funded programs, but Alexander v. Sandoval (2001) barred private plaintiffs from suing to enforce disparate‑impact regulations; a private §601 claim requires proof of intentional discrimination, which is rarely documented. The CAA’s citizen‑suit provision lets communities enforce violations of specific permits, yet it does not address the acceptability of cumulative lawful pollution. Consequently, a project can satisfy each individual legal requirement while no decision‑maker must determine whether the combined burden on the community should be permitted at all.
Local Power as a Counterexample
In contrast to the federal framework, Monterey Park, California, demonstrated how local authority can directly block harmful projects. In June 2026 voters overwhelmingly approved Measure NDC, amending the city’s land‑use law under Article XI, section 7 of the California Constitution and California Government Code § 65800, which grants municipalities zoning authority. Despite industry warnings that the measure would cost jobs, investment, and tax revenue—labeling Monterey Park “closed for business”—voters concluded that projected economic benefits did not outweigh anticipated environmental and infrastructural costs. This local zoning power changed the governing rule itself, preventing city officials from approving the prohibited use, something federal statutes like NEPA, Title VI, or the CAA cannot do because they regulate process or individual sources rather than outright prohibition.
A Three‑Part Federal Reform Proposal
The article proposes a three‑part federal framework to close the cumulative‑harm gap: (1) NEPA review of functionally connected data‑center infrastructure should incorporate cumulative‑exposure analysis as a substantive factor in permitting decisions, not merely a disclosure requirement; (2) The ability of affected residents to challenge permitting decisions that materially worsen environmental conditions in minority communities should not hinge on proving deliberate discriminatory intent, addressing the Title VI limitation highlighted by Sandoval; (3) Agencies should possess authority to condition or deny permits when a project would materially worsen conditions in an already overburdened community, filling the CAA’s omission of a cumulative‑burden threshold. Under current law, a project may meet each individual legal test while no entity is required to decide whether the total burden on the community is acceptable.
Section II: Cost‑Shifting Under the Federal Power Act
Section II shifts focus to the economic side of AI expansion. Executive Order 14318, issued by President Trump, proclaimed a “golden age” of American industry driven by AI data centers and called for easing federal regulatory burdens to accelerate construction. Yet the extraordinary electricity demands of these facilities shift costs onto local communities; for example, xAI’s Colossus 2 data center draws 1,563 megawatts—enough to power over one million homes—and areas with high concentrations of data centers have seen average electricity price increases of 267 %. The Federal Power Act (FPA) establishes the Federal Energy Regulatory Commission (FERC) as the primary regulator of interstate electricity commerce, with a statutory obligation under Section 205(a) to ensure that rates and charges are “just and reasonable” and to prevent any “unreasonable difference” based on locality or class of service. Cost‑shifting runs contrary to this standard by inequitably allocating higher costs to certain consumers, particularly nearby residents who receive few of the data centers’ benefits.
FERC’s Current Stance and State‑Level Action
Although the FERC has issued “show cause” orders under Section 206 of the FPA urging regional transmission organizations (RTOs) to expedite the integration of large loads, it has refrained from adopting targeted rules to restrict or limit data‑center interconnection, arguing that rising demand and investment in new generation will benefit the electric markets in the long run. State regulators, however, have pushed back. A joint statement from Maryland, Ohio, Delaware, and Illinois ratepayer advocates urged the FERC to require new customers to internalize all connection costs. In Pennsylvania, the Public Utility Commission investigated PPL Electric Utilities Corporation over over‑billing, leading to a settlement that separates large‑load customers into a distinct rate class—an approach the article cites as a viable model for federal adoption. The Seventh Circuit’s decision in Illinois Commerce Commission v. FERC (2014) reinforced that utility projects should not shift “grossly disproportionate” shares of costs onto utilities unlikely to share the benefits, a principle directly applicable to data‑center cost‑shifting.
Legal Basis for FERC to Prevent Cost‑Shifting
Under Section 205 of the FPA, the FERC must enforce just and reasonable rates; under Section 206(a), if it finds an existing rate discriminatory, preferential, or otherwise unreasonable, it is required to determine and enforce a new reasonable rate. The FERC already uses similar mechanisms for grid reliability: under FERC Order No. 2023, RTOs must make risky connections pay for necessary transmission upgrades, thereby internalizing costs. The Supreme Court’s decision in Fed. Energy Regulatory Comm’n v. Elec. Power Supply Ass’n (2016) affirmed the FERC’s authority over wholesale‑rate practices that indirectly affect retail rates. Consequently, the FERC can legally require large‑load customers such as data centers to internalize their cost‑shifting burdens, ensuring that the statutory duty to protect consumers prevails over executive‑order calls for deregulation.
Section III: Chemical Disposal Under the TSCA
Section III examines how the Toxic Substances Control Act (TSCA) reaches data‑center operations. The TSCA, enacted in 1976 and amended by the Frank R. Lautenberg Chemical Safety for the 21st Century Act in 2016, authorizes the EPA to regulate chemical substances throughout their life cycle. Although the statute does not mention data centers by name, its broad definition—covering “any organic or inorganic substance of a particular molecular identity”—encompasses the fluorinated coolants (including PFAS), lead‑acid and lithium‑ion battery compounds, and flame retardants such as tetrabromobisphenol A (TBBPA) and chlorinated phosphate esters used in server hardware and cooling systems. Under Sections 8(a) and 8(b), the EPA can require reporting on production, use, and exposure data for these TSCA‑listed substances, meaning data centers are already subject to reporting obligations.
Disposal Pathways and the Enforcement Gap
The article identifies two primary disposal pathways that pose environmental risk. First, cooling‑tower blowdown releases water treated with borates, phosphates, nitrites, and isopropylated phosphate—a TSCA‑listed substance—into municipal sewage or surface waters. While the Clean Water Act governs discharge into waterways, the TSCA regulates the substances themselves before and during disposal, offering a complementary regulatory hook. Second, end‑of‑life server hardware containing TBBPA and chlorinated phosphate esters can leach into soil and groundwater through landfill disposal or be released to the atmosphere via improper incineration; Section 3 of the TSCA covers substances whose manufacture, processing, distribution, use, or disposal may present an unreasonable risk of injury, bringing these disposal practices within the EPA’s authority under Section 6 to restrict unsafe disposal methods. Despite this clear statutory reach, the EPA has not publicly interpreted the TSCA as applying to data‑center operations, initiated enforcement actions, or incorporated data centers into its ongoing PFAS rulemaking. The enforcement gap exists because the agency has yet to apply its existing authority to this rapidly emerging industrial category, even though the Lautenberg Act amendments strengthened EPA’s ability to conduct risk evaluations and set deadlines for action.
Conclusion: Bridging the Gaps
Together, the three sections reveal a systemic shortfall: federal environmental, energy, and chemical statutes excel at regulating individual permits, rates, or substances but lack mechanisms to evaluate whether the combined burden of multiple lawful actions crosses a threshold of acceptability for already overburdened communities. Executive orders that once forced agencies to consider cumulative impacts have been rescinded, leaving communities reliant on procedural rights (to be heard) rather than substantive rights (to refuse additional harm). Local governments sometimes retain the power to block harmful projects outright, a lever largely absent at the federal level. Reform proposals—embedding cumulative analysis into NEPA, easing disparate‑impact challenges under Title VI, and granting agencies authority to deny permits that would materially worsen conditions in overburdened areas—could close the gap. Similarly, clarifying FERC’s duty to prevent cost‑shifting and compelling the EPA to exercise its TSCA authority over data‑center chemicals would ensure that the benefits of AI expansion are not achieved at the expense of public health, environmental integrity, or equitable energy rates.
