Global Environmental Regulation, Policy, M&A & Market Update

EPA has proposed to streamline the New Source Review (NSR) permitting process for minor sources by eliminating the minimum federal regulatory requirements for public participation:

• What changes: signed July 1 and published in the Federal Register July 7, the proposal would let state and local air agencies — not EPA — determine whether, when, and to what extent public participation in minor NSR programs is necessary to assure National Ambient Air Quality Standards are met.^[1],[2]
• Timeline: a virtual public hearing was held July 22; written comments are due August 21, 2026.^[2],[4]
• What's unaffected: existing state programs continue under current SIP-approved requirements unless voluntarily revised, and the proposal doesn't touch Prevention of Significant Deterioration (PSD) permits, Nonattainment NSR permits, or Title V operating permits — those stay federally anchored.^[3]
• EPA's framing: reduced administrative burden and faster permitting for industrial, manufacturing, and energy projects, with no change to emission standards or substantive protections.^[1]
• Broader context: this sits alongside a May 11 proposal to redefine "begin actual construction" for more pre-permit site-work flexibility, and updated Title V guidance letting permit review run concurrently with public comment.^[2]

EPA proposed on July 13 to approve the Alabama Department of Environmental Management's (ADEM) Coal Combustion Residuals (CCR) permit program under RCRA — the same 2021 application the Biden EPA denied in 2024 for applying technical standards it judged less protective than federal rules:

• The reversal: Administrator Zeldin called it "yet another win for cooperative federalism."^[5] If finalized, ADEM — not EPA — decides whether Alabama utilities can leave coal ash containing arsenic, lead, mercury, and other heavy metals in unlined ponds along the state's waterways, including the ecologically significant Mobile-Tensaw Delta.^[5],[7]
• Scale: more than 117 million tons of coal ash sludge are currently stored in unlined ponds on Alabama waterways — Alabama Power operates six, TVA two, and PowerSouth one.^[5]
• What stays in place: existing ADEM-issued permits would still be reviewed and reissued under the newly approved rules, with a public comment opportunity on each — approved states cannot maintain CCR standards less protective than federal rules, so that constraint moves to a state-administered process rather than disappearing.^[7]
• Timeline: a virtual public hearing is set for September 3; comments close September 14, 2026.^[6]
• Growing list: Louisiana, Georgia, North Dakota, Oklahoma, Texas, Virginia, and Wyoming already have proposed or final CCR primacy, with EPA anticipating decisions for at least two more states soon.^[8]

Front one: a coalition challenges a data-center PFAS coolant.

• The filing: seventeen environmental organizations led by Earthjustice filed formal TSCA comments July 15 asking EPA to deny a premanufacture notice for Opteon 2P50 — a Chemours fluorinated fluid designed for two-phase immersion cooling in data centers.^[9],[10]
• The dispute: the coalition characterizes the compound as a PFAS on persistence, mobility, and bioaccumulation grounds; Chemours describes it instead as a hydrofluoroolefin (HFO) that degrades quickly in the atmosphere. The coalition contends HFOs break down into shorter-chain PFAS, including trifluoroacetic acid (TFA), and cites a June 2026 European Chemicals Agency opinion proposing TFA be classified as toxic to reproduction.^[10]
• Status: as of July 20, the environmental coalition was the sole commenter in the docket.^[11]
• Why it exists: developers have promoted two-phase immersion cooling to cut data centers' heavy water use — but the systems typically substitute PFAS "forever chemical" fluid for water, a tradeoff few outside the industry have scrutinized until now.^[9]

Front two: the FAA moves to waive environmental review for space infrastructure.

• The proposal: announced July 28, published in the Federal Register July 30, it would let the FAA waive requirements under 13 federal environmental and natural-resource laws — including NEPA, the Endangered Species Act, and portions of the Clean Water Act, Clean Air Act, and National Historic Preservation Act — for qualifying commercial space launch, reentry, and spaceport licenses.^[12],[13]
• The legal hook: the agency cites a 2025 Supreme Court ruling (Seven County Infrastructure Coalition v. Eagle County) describing NEPA as having "transformed from a modest procedural requirement into a blunt and haphazard tool" used to slow infrastructure projects.^[12]
• Scale: FAA-authorized commercial space operations hit a record 204 in FY2025, with the agency's forecast projecting growth from 214 this year to 507 by 2036. Comments are due August 31, 2026.^[12],[14]
• The catch: legal observers note the proposal goes further than the precedent it cites — it would eliminate environmental review outright for entire categories of launch licenses, rather than simply narrowing NEPA's scope, and litigation challenging that reach is widely expected.^[13]

EPA issued a final rule July 28 extending certain compliance dates in its December 2024 risk management rules for perchloroethylene (PCE) and carbon tetrachloride (CTC) under TSCA:

• New dates: for both chemicals, initial inhalation-exposure monitoring moves from June 2026 to June 21, 2027; meeting the exposure limit, establishing a regulated area, and implementing respiratory protective equipment moves to September 20, 2027; PCE's exposure-control-plan deadline for non-federal entities extends to December 2027.^[15],[16]
• What EPA says it isn't doing: the "timeline adjustment does not weaken any existing protection," and the underlying unreasonable-risk finding for both chemicals is unchanged — both rules remain under separate court challenge.^[15]
• Cost estimate: EPA puts 20-year annualized cost savings from the extension at $6.2–8.3 million.^[16]

Asbestos remains the sector's highest-stakes pending TSCA matter:

• In court: the Fifth Circuit heard oral argument June 1 in Texas Chemistry Council v. EPA, challenging EPA's 2024 Part 1 Chrysotile Asbestos Rule — the same court that vacated EPA's original 1989 asbestos ban, and a panel that has already asked litigants to address standing questions. A decision remains pending.^[17],[18]
• In rulemaking: EPA opened an information request June 23 to inform a "durable" TSCA regulation covering legacy uses and disposal of non-chrysotile and chrysotile asbestos fiber types and asbestos-containing talc (Part 2), with a proposed rule not expected until 2027.^[17]

Water infrastructure remains one of the most consistent secular themes in our coverage:

• Building on last issue: the WIFIA small-community fee waiver we covered July 24 eliminates the $25,000 application fee and roughly $156,000 average credit processing fee for communities of 25,000 or fewer through FY2026–2027, worth nearly $200,000 per applicant.^[19]
• Continuing emphasis: EPA keeps pushing accelerated investment across drinking water, wastewater, and stormwater through both WIFIA and State Revolving Fund (SRF) channels, including outreach specifically targeted at smaller communities that have historically struggled to navigate federal financing programs.^[19]
• Why it's different: unlike this week's permitting and chemical stories, this driver isn't contingent on any single administration's deregulatory posture — aging pipes, treatment plants, and stormwater systems don't change with the political cycle, even as financing emphasis (small-system access, rural outreach) shifts administration to administration.

Our July 24 issue covered the July 21 filing of a multi-state petition challenging EPA's HFC phase-down rollback — eighteen states, Washington, D.C., and New York City argue the rule's extended compliance timelines conflict with the American Innovation and Manufacturing Act. The rule took effect July 27 as scheduled; no rulings, stays, or new filings have been reported this week. We'll flag the next material development — a briefing schedule, a stay motion, or oral argument date — as it emerges.

We reviewed the week's deal flow across hazardous waste, water treatment, environmental consulting, and renewables-adjacent services and found nothing that met our threshold for inclusion — no transactions with disclosed or estimable value, strategic significance, or a clear read-through for the sector. Rather than fill this section with minor tuck-ins to maintain a consistent format, we're saying so directly.

Rather than another PFAS-treatment-technology story, this week's technology theme is AI-enabled environmental monitoring and contaminant analytics:

• The driver: as regulated contaminant lists expand — EPA's proposed Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) alone would add monitoring for 30 currently unregulated substances — utilities and industrial facilities face a data-management problem as much as a treatment problem: more contaminants, more sampling points, more reporting obligations, and more historical data to reconcile across aging municipal systems.
• The opening: this creates a structural opening for software and sensor companies alongside traditional engineering firms.
• What's becoming necessary infrastructure: predictive monitoring platforms that flag anomalies before they become compliance violations; automated leak-detection sensor networks (relevant to both water contaminants and this week's refrigerant-leak-detection thread); and data-management platforms that can ingest expanding contaminant panels without a proportional headcount increase.

The connecting thread across this week's air permitting and coal-ash stories is cooperative federalism — federal environmental oversight increasingly shifting implementation authority to states while maintaining the underlying substantive standards. For consulting and engineering firms, the net effect is more state-specific compliance work, not less work overall, as a single federal standard fragments into dozens of state-administered variants.

Layered on top of that decentralization is a second theme: AI and data-center infrastructure is generating environmental-compliance demand from multiple, sometimes contradictory directions — a PFAS chemical dispute on one side, an environmental-review waiver on the other — both traceable to the same underlying buildout velocity outrunning the pace regulatory review was designed for.

In the current environment, the strongest positioning continues to favor platforms diversified across compliance categories and jurisdictions — the pattern holds whether the driver is federal decentralization, chemical classification disputes, or infrastructure buildout velocity.
