The guidance concerns the Nonattainment New Source Review program, which applies to areas that do not meet one or more National Ambient Air Quality Standards. The program governs permitting for projects in communities where air pollution levels are above those federal standards.

What the guidance says

Under the EPA’s clarification, a permitting authority does not necessarily have to wait for the required credits to be secured before issuing a qualifying construction permit. Instead, the authority may issue the permit with conditions that are enforceable and address the credit requirement.

Emission-reduction credits are part of the compliance framework for projects subject to Nonattainment New Source Review. The guidance changes the timing question—when credits must be secured in relation to permit issuance—for certain permits. It does not eliminate the requirement for emissions offsets or equivalent enforceable compliance measures.

The agency said uncertainty about when emission-reduction credits must be obtained has contributed to permitting delays. EPA described the guidance as a way to give states and other permitting authorities more flexibility in handling that timing while maintaining or improving air quality.

The change is therefore conditional rather than automatic. A permit may proceed before credits are secured only when the project qualifies under the relevant program and the required enforceable conditions can be included. The permitting authority responsible for the individual decision will determine how those conditions apply.

How it could affect projects

The immediate effect is a potential change in the sequence of permitting steps for some projects in nonattainment areas. A qualifying project could move through permit issuance before the required emission-reduction credits have been secured, rather than waiting for that step to be completed first.

That flexibility could allow some projects to move toward construction sooner in areas that do not meet national air-quality standards. The underlying emissions requirement remains part of the permit framework, however, because the permit must contain enforceable conditions addressing the required credits or equivalent compliance measures.

The guidance applies nationally to Clean Air Act permitting authorities in nonattainment areas. State and other permitting authorities will apply it when reviewing individual construction permits under the Nonattainment New Source Review program. The EPA’s action does not itself approve a specific project or require every permit in a nonattainment area to be issued before credits are secured.

Implementation will depend on the facts of each permit and on the authority handling the review. Projects must still fall within the program’s scope, and the permit must include conditions that can be enforced. The guidance thus provides a framework for permitting decisions rather than a blanket authorization covering all construction permits.

The EPA’s announcement does not identify how many projects or permits may be affected, and it does not quantify any expected change in construction activity or emissions. The guidance establishes the agency’s position on the timing of credit acquisition; its practical effects will depend on how permitting authorities use that position in individual cases.

For communities covered by the program, the central issue remains the relationship between project permitting and emissions control. EPA said the guidance is intended to reduce delays while maintaining or attaining air-quality standards. Whether a particular project advances under the approach will depend on the permit’s enforceable conditions and the decision of the responsible permitting authority.

The en banc U.S. Court of Appeals for the District of Columbia Circuit ruled 6-4 that the Environmental Protection Agency likely violated the 2022 law when it ended the grants and sought to recover money that had already been distributed. The decision is a significant setback for the administration’s effort to reverse climate-financing awards made under the Inflation Reduction Act.

What the court decided

Six of the court’s 10 participating judges agreed with the lower court’s conclusion that EPA likely acted unlawfully in terminating the awards and pursuing clawbacks of disbursed funds. The ruling sent the challenge back toward the lower court and revived legal protections for organizations that received grants.

The decision temporarily limits the administration’s ability to carry out the terminations and clawbacks while the case continues. It does not permanently restore every grant, resolve the status of every dollar already distributed or determine the future of each project connected to the program.

The longer-term effect on recipients and projects will depend on subsequent court orders and further litigation. The administration was considering whether to ask the Supreme Court to intervene, but the court’s ruling did not itself settle that next step.

A national climate-financing program

The case centers on the Greenhouse Gas Reduction Fund, a national climate-financing program authorized through the Inflation Reduction Act. The fund includes approximately $27 billion for clean-energy and climate projects.

That scale makes the dispute larger than a disagreement over individual grants. The ruling affects a federal program designed to direct billions of dollars toward climate-related financing and constrains an effort to dismantle or reverse commitments made after Congress authorized the money.

The litigation also involves nearly $3 billion in Environmental and Climate Justice grants, according to E&E News. Those grants are part of the broader legal fight over climate awards made during the Biden administration.

EPA allegations and a recipient’s response

EPA has presented the grant terminations as justified by allegations of mismanagement and potential fraud involving grant administrators. Those allegations remain disputed and were not established as findings by the appeals court’s ruling.

Climate United Fund, one of the affected recipients, said it was owed about $7 billion and rejected the administration’s accusations. EPA lists Climate United’s award at approximately $6.97 billion.

The nearly matching figures illustrate the size of the stakes for a single recipient, but they do not resolve the parties’ disagreement over how much money was owed, how the award should be treated or whether the administration’s allegations justified termination. The appeals court’s decision addressed the legality of EPA’s action at this stage of the litigation rather than issuing a final accounting for every recipient.

What happens next

The case now moves back toward the lower court, where the practical effects of the appeals court’s ruling will be addressed. Further orders will help determine how the protections apply to grant recipients and how the government’s efforts to terminate awards or recover disbursed funds proceed.

The administration may also pursue Supreme Court review. Until the next court actions, the ruling preserves legal protection for organizations involved in the program while the broader fight over the grants continues.

For recipients, the immediate consequence is protection against the administration proceeding as though the awards had been lawfully terminated. For the government, the 6-4 decision narrows its effort to undo climate-financing commitments made under the Inflation Reduction Act. The ultimate status of disbursed funds and individual projects remains tied to the next stages of the litigation.

The proposal concerns state and local permitting programs operating under federal Clean Air Act requirements. If finalized, the revised framework would leave states and local governments to administer their own programs, including decisions about how residents and other members of the public participate in permitting for new or modified minor sources.

The action is a proposed rule, not a final regulation. The EPA announcement does not identify a formal deadline for public comments or indicate that the rule has been finalized.

What would change

New Source Review is the federal permitting system used when facilities are built or modified in ways that may affect air pollution emissions. The proposal specifically addresses minor sources, which are facilities that emit pollutants below the thresholds used to classify major sources.

Under the proposed approach, the federal government would no longer set minimum public-participation requirements for those minor-source permitting decisions. States and local permitting authorities would continue to run their programs, but the procedures used to notify communities or receive comments could vary depending on where a facility is located.

That does not mean public participation would automatically disappear in every state or locality. A state or local government could retain existing procedures or adopt additional ones. The proposed federal change would remove the minimum requirements imposed at the federal level.

The potential result is a more varied permitting landscape. Communities in different states, or even under different local permitting authorities, could encounter different practices for learning about proposed facilities and commenting on them if the rule is finalized and implemented.

Why the proposal matters

Minor-source permits cover facilities below major-source thresholds, but the permitting decisions can still affect how communities receive information about new or modified facilities in their area. Public-participation procedures can provide a way for residents and other interested parties to learn about a permit application and communicate concerns to the authority handling it.

Removing a federal floor could give state and local agencies more flexibility to design or administer permitting systems. It could also mean that the opportunities and procedures available to the public depend more heavily on the rules of the state or locality involved.

The proposal addresses public-participation requirements. The announced action does not establish that pollution limits would be weakened, and it does not quantify how many facilities or emissions would be affected.

What happens next

The EPA must proceed through the federal rulemaking process before the proposal can become a final regulation. The agency’s announcement identifies the action as a proposed rule, so the existing framework remains the relevant regulatory status unless and until EPA takes further action.

Any final rule could determine whether the proposed removal of minimum federal requirements is adopted as written, revised, or not finalized. States and local permitting authorities would then have to administer their programs under whatever federal requirements ultimately remain.

For communities, the practical question is how each state and local authority would handle notice and public comments for minor-source permits under a finalized rule. The EPA proposal would shift more of that responsibility to those authorities while preserving the broader role of state and local programs within the Clean Air Act permitting system.

The proposed resolution would require South Bow (USA) LP and South Bow Infrastructure Operations Inc. to pay more than $26.8 million in civil penalties. It also calls for an estimated $40 million in additional prevention and restoration work, plus a separate $3 million payment to the State of Kansas.

The filing is a proposed federal enforcement action, not a final settlement or a final court finding of liability. The consent decree must first go through a 30-day public-comment period, and its terms could change after public input or court review.

What the government alleges

The case concerns a Keystone Pipeline rupture on Dec. 7, 2022. According to the complaint, nearly 13,000 barrels of crude oil — approximately 543,000 gallons — entered land and Mill Creek.

The complaint says the oil covered about 3.5 miles of the creek bank-to-bank downstream from the rupture. It also reports that more than 2,700 animals were killed or affected.

Those figures come from the federal complaint. They describe the government’s allegations and reported damage connected to the incident; they are not presented here as findings independently established beyond the complaint.

The proposed defendants are South Bow (USA) LP and South Bow Infrastructure Operations Inc. The Justice Department’s action addresses alleged federal Clean Water Act liability arising from the Washington County rupture. The packet does not indicate that the proposal resolves unrelated incidents involving the Keystone system.

Money and restoration obligations

The proposed civil penalty exceeds $26.8 million. In addition, the agreement estimates that South Bow would undertake about $40 million in prevention and restoration work. That work is intended to reduce the risk of future discharges and address damage associated with the rupture.

The proposed decree also directs a $3 million payment to Kansas. The payment is separate from the proposed federal civil penalty and from the estimated cost of prevention and restoration work.

The financial figures therefore describe several different parts of the proposed resolution: a federal civil penalty, work intended to prevent future discharges and restore affected areas, and a payment to the state. None of those proposed terms has become a final judgment.

Cleanup began before the proposed agreement

A 2023 cleanup order from the Environmental Protection Agency preceded the proposed consent decree. According to the Justice Department’s account, that order led to the removal of oil and restoration work involving aquatic habitat, stream banks and shorelines.

The proposed agreement follows that earlier cleanup action but adds the broader financial and prevention terms described in the filing. The packet does not provide a final accounting of the cleanup work already completed or say that all restoration has concluded.

The incident involved the Keystone system, an interstate pipeline network that extends 2,687 miles. The federal case is tied to one rupture in Kansas, but its significance extends beyond the immediate location because it concerns federal environmental requirements for a major pipeline system.

What happens next

The proposed consent decree will be available for public comment for 30 days. That process gives members of the public an opportunity to respond before the agreement can proceed toward final court review.

The packet does not provide an exact closing date for comments. Until the comment period and court review are complete, the proposed penalty, Kansas payment and prevention and restoration obligations remain subject to change.

The July 10 filing establishes the next procedural step, but it does not end the case. The ultimate settlement terms and whether the proposed decree is entered as a final judgment remain unsettled.

The proposal, announced May 18, 2026, would keep the existing federal maximum contaminant levels for PFOA and PFOS in place. The agency’s proposed change concerns the timing of compliance for qualifying water systems, not a change to those limits.

What the proposal would do

Under the proposal, eligible drinking-water systems could ask EPA for as much as two additional years to meet the federal requirements. The potential compliance endpoint would therefore be 2031, according to the agency’s description of the proposed rule.

The rule would apply to public drinking-water systems under the federal Safe Drinking Water Act across the United States. That makes the proposal a nationwide regulatory issue for water providers that are subject to the federal requirements, although the source reviewed does not specify how many systems would qualify for an extension.

The distinction between the limits and the deadline is central. EPA says the proposal would preserve the maximum contaminant levels for PFOA and PFOS. It would not, as described by the agency, weaken those levels. Instead, it would create a possible extension of the time available for eligible systems to comply.

Where the proposal stands

EPA held a virtual public hearing on July 7, 2026. The public-comment period closed July 20. The agency’s rule page was last updated July 23, 2026, making the post-comment status the latest development identified in the approved record.

No final rule or final decision had been announced in the source reviewed. The extension therefore remains a proposal, and no water system can be described from this record as having received a final extension.

The end of the comment period means the public submission window identified by EPA has closed, but the source does not provide a date for a final agency action. It also does not identify which systems would be eligible, how many would seek extensions or how many residents or utilities could be affected.

Why the timing matters

For public drinking-water providers, a final version of the proposal could affect the timetable for meeting federal PFOA and PFOS requirements. Systems that qualify and receive approval could have additional time, while the federal maximum contaminant levels would remain in place under the proposal.

For people who rely on public water systems, the immediate development is a proposed change in compliance timing rather than a completed change to the federal limits. The source does not provide an estimate of affected residents, identify particular utilities or describe system-specific compliance plans.

EPA’s next known step is consideration of the proposal after the July 20 comment deadline. The approved record does not state when the agency will issue a final rule or whether the proposed extension will be adopted. Until that happens, the two-year extension and the possible 2031 deadline are not final requirements or permissions.

First Assistant U.S. Attorney Bill Essayli made the EPA request on July 16, 2026. The request is an investigation referral, not a finding that an environmental exposure caused the illnesses or that federal environmental laws were violated.

Six reported Ewing sarcoma cases

The initial Ladera Ranch reporting involved six children whose families said they had been diagnosed with Ewing sarcoma, a rare form of cancer. Ladera Ranch is an unincorporated Orange County community represented by the county’s Fifth District and has approximately 26,000 residents, according to the Orange County Board of Supervisors’ release.

NBC Los Angeles later reported that about a dozen rare cancer cases had been identified in Ladera Ranch and other Orange County cities. That broader figure includes multiple communities and should not be attributed solely to Ladera Ranch. It also is distinct from the six reported Ewing sarcoma cases in Ladera Ranch.

The available reporting does not establish a shared cause, and the cases have not been officially declared a cancer cluster. The EPA request and state review are intended to help determine what, if anything, the reported cases may have in common.

State review urged to move faster

On July 17, Orange County Supervisor Katrina Foley sent a letter to California Department of Public Health Director and State Public Health Officer Dr. Erica Pan. Foley asked the department to expedite its review and provide timely, transparent updates.

Families and other residents continued pressing for answers at a July 21 community town hall, where hundreds of people attended and demanded a broader investigation, according to local television reporting.

For families in Ladera Ranch, the confirmed development is that federal and state reviews have been requested or urged—not that investigators have identified an environmental source. The timing and scope of any EPA or state investigation remain open.

Residents should watch for agency findings, health-data reviews and any public recommendations. Until those steps produce evidence, the reported cases remain a serious public-health concern under review rather than proof of an environmental cancer cluster.

The proposal, announced May 18, 2026, would preserve the existing federal maximum contaminant levels for both chemicals. It would not automatically give every water system more time, and it would not eliminate or weaken the limits themselves.

Instead, qualifying systems could request an extension of up to two years. The proposal would change the timetable for compliance for systems that receive approval, while keeping the federal limits in place.

What the proposal would change

PFOA and PFOS are the two chemicals covered by the proposed compliance extension. The EPA describes the action as a federal drinking-water rule applying to public water systems subject to the national maximum contaminant levels for those chemicals.

Under the proposal, an eligible system could seek additional time rather than being required to meet the limits on the existing schedule. The maximum extension would be two years, with compliance potentially running through 2031.

The distinction between a request and an approved extension is central. The proposal does not state that all public water systems would receive extra time automatically. It also does not establish that any particular system has qualified for an extension.

The approved source packet does not identify how many systems have requested, or may qualify for, additional time. It also does not provide a list of systems that would be covered by an extension.

National implications for water systems

Because the proposal concerns federally enforceable drinking-water limits, it could affect public water systems across the United States. The main immediate consequence would be a possible change in the compliance timetable for systems that are eligible and receive approval.

For water providers, the proposal creates a potential two-year window beyond the existing schedule. For people served by those systems, the practical question is whether their provider seeks an extension and whether the EPA approves it. The packet does not provide system-by-system information or describe changes in measured contamination levels.

The proposal also does not change the federal maximum contaminant levels for PFOA and PFOS. The EPA’s action is about implementation timing, not a new numerical limit or a change to health guidance, according to the approved information.

Public hearing and comment period

The EPA held a virtual public hearing on July 7, 2026. The agency’s public-comment period closed July 20, 2026.

Those dates mark the completed public input steps identified in the source material. The proposal remains pending and is not a final rule.

The EPA’s announcements and schedules page lists active federal environmental rulemaking and comment deadlines. It also indicates that regulatory actions remain in proposed or comment-stage status unless they are separately finalized.

What happens next

The next known step is EPA action on the pending proposal after the hearing and comment period. The agency has not announced a final rule or a final implementation schedule in the selected source.

Until a final rule is issued, the proposal should not be treated as a completed change in federal drinking-water requirements. Public water systems are not automatically granted the proposed two-year extension, and the source packet does not establish how many systems could ultimately qualify.

If finalized, the rule would determine how eligible systems request additional time and how the possible extension to 2031 is implemented. For now, the verified development is the EPA’s proposal to preserve the PFOA and PFOS limits while considering a longer compliance timetable for eligible systems.

The complaint and lodged decree were filed July 10 in the U.S. District Court for the District of Kansas by the United States, on behalf of the Environmental Protection Agency, and the State of Kansas through the Kansas Department of Health and Environment. The defendants are South Bow (USA) LP and South Bow Infrastructure Operations Inc., formerly known as TransCanada Keystone Pipeline LP and TC Oil Pipeline Operations Inc.

What the proposed settlement would require

The proposed agreement separates the financial and compliance obligations into three parts. South Bow would pay a federal civil penalty of $26,867,789, with the money deposited into the federal Oil Spill Liability Trust Fund.

The company would also complete prevention and detection work that it estimates will cost approximately $40 million. Separately, the proposed decree requires a $3,080,000 contribution to Kansas for natural-resource restoration projects. Those amounts are not one combined cash penalty.

The proposed safeguards include acoustic leak-detection inspections at least annually, inertial-measurement-unit and bending-strain assessments at least every two years, and ultrasonic circumferential-crack-tool reinspections at least every five years. The decree also calls for annual integrity-threat assessment updates, limits on pressure and thermal cycling, engineering assessments before significant operating changes or flow increases, and expanded reporting and training procedures.

Other provisions address construction-inspector certification, girth-weld reliability, digital inspection records, automatic deficiency flagging, real-time exception reporting, geotagged photographs and procedures for recording and evaluating pipe movement when a section is excavated. South Bow would submit semiannual compliance reports and face stipulated penalties for certain violations of the decree.

These would be case-specific obligations for South Bow and entities bound by the decree. They would not create a new nationwide pipeline rule. The decree also says it is not a permit or a modification of a permit, and that South Bow must continue complying with other applicable federal, state and local requirements.

What happened in Washington County

The rupture occurred December 7, 2022, near Washington, Kansas, on the Keystone segment running from Steele City, Nebraska, to Cushing, Oklahoma. According to the complaint, at least 12,937 barrels, or 543,354 gallons, of diluted bitumen escaped from the pipeline and reached Mill Creek, a tributary connected to the Kansas River.

The complaint alleges that oil contaminated approximately 35 acres and affected a 3.65-mile segment of Mill Creek. It says oil covered the creek bank to bank in a layer about an inch thick for roughly three miles downstream of the rupture. More than 2,700 animals, including fish, birds, mammals, reptiles and invertebrates, were killed or impacted, according to the filing.

Cleanup lasted more than 10 months. The complaint says crews treated more than 54 million gallons of contaminated water, recovered about 655,000 gallons of oil, including oil remaining in the pipeline, and removed approximately 200,000 tons of impacted soil, sediment and debris. The filing also says South Bow continues long-term environmental monitoring and remediation under KDHE oversight.

What the documents allege about the failure

The complaint says the oil exited through a circumferential crack near a girth weld in a bend assembly known as TAG 98. It alleges that construction stress and inadequately compacted soil caused the assembly to ovalize, or deform from a circular shape.

The complaint cites a post-spill investigation by the federal Pipeline and Hazardous Materials Safety Administration that attributed the bending stress to inadequately compacted soil beneath the pipe. The filing says a construction-caliper inspection was completed before replacement fittings were installed in 2010 but was not repeated afterward.

The complaint also says ovality was identified as a potential concern during internal pipe-monitoring inspections in December 2012. The segment was excavated in March 2013, but the filing says it was not replaced and no analysis was performed at that time to understand the integrity effects of the ovality. The complaint further alleges that flow rates began increasing in 2016 and that ramp-up testing to increase flow began December 5, 2022, two days before the rupture.

Those statements are allegations, not adjudicated findings. South Bow does not admit the complaint’s allegations or liability under the proposed decree.

How to comment

Written comments are due by August 14, 2026. The Federal Register notice says comments may be submitted by email to pubcomment-ees.enrd@usdoj.gov or by mail to the Assistant Attorney General, U.S. DOJ—ENRD, P.O. Box 7611, Washington, DC 20044-7611. Comments should identify United States and the State of Kansas v. South Bow (USA) LP and South Bow Infrastructure Operations Inc. and DOJ reference number 90-5-1-1-12906.

The notice warns that written comments may be filed in whole or in part on the public court docket without additional notice to the commenter. The proposed decree must remain lodged for at least 30 days for public notice and comment. The decree says the United States may withdraw or withhold its consent if comments disclose facts or considerations showing that the agreement is inappropriate, improper or inadequate.

What happens next

After the comment period, the Justice Department will decide whether to continue supporting entry of the proposed decree, and the District of Kansas court will determine whether to enter it. Under the decree, its effective date would be the date the court enters it or grants a motion to enter it, whichever occurs first.

If approved, the court would retain jurisdiction to resolve disputes and enforce compliance. The settlement would resolve the civil claims described in the complaint through the date of lodging, while the United States and Kansas would retain certain other legal and equitable remedies.

The U.S. Court of Appeals for the D.C. Circuit is holding its decision for several days while EPA considers whether to ask the Supreme Court to intervene. Until the next procedural step, the funds remain frozen or otherwise unavailable.

What the court decided

Six of the 10 judges who participated agreed that the Trump administration’s EPA likely violated the law when it terminated the grants and sought to recover or block funds. The majority concluded that the agency could not cancel the awards based on its policy and oversight objections without identifying a supported violation of the grant agreements.

Four judges broadly sided with EPA. The court’s split matters because the decision was not unanimous, and one of the six judges who agreed the terminations were improper separately said Congress’s later changes to the program complicated whether the groups could access the funds going forward.

EPA Administrator Lee Zeldin and the administration had accused the nonprofit recipients of mismanagement, conflicts of interest and possible fraud. The groups disputed those allegations. The court’s ruling addressed whether EPA lawfully terminated the grants; it did not establish that every oversight concern raised by the agency had been resolved.

How much money is involved

Congress created the Greenhouse Gas Reduction Fund through the Inflation Reduction Act and appropriated $27 billion across three programs: the $14 billion National Clean Investment Fund, the $6 billion Clean Communities Investment Accelerator and the $7 billion Solar for All program.

About $20 billion was awarded to eight nonprofit organizations through the first two programs. That grant pool is central to the litigation, which includes five of those recipients. The $27 billion total should not be described as though every dollar is directly at issue in this lawsuit.

The grants were intended to support financing for small clean-energy projects, energy-efficient buildings and transportation, including work in low-income and disadvantaged communities. The nonprofit recipients were expected to use the funding to make loans, attract private investment, support community lenders and provide technical assistance.

Why the money is not flowing yet

The ruling is a legal victory for the grantees, but recipients do not yet control the funds. The court’s temporary hold gives EPA time to decide whether to seek Supreme Court review and, if it does, whether to ask the justices for additional relief.

Households should not expect an immediate change in energy bills, building upgrades, transportation projects or local financing programs. Any practical effect will depend on further action by EPA and the courts, including whether the funds are released and how the grant agreements are administered.

How the case reached the full court

The dispute followed EPA’s 2025 decision to freeze and terminate the grants. A federal district judge had ordered the agency and Citibank to continue supporting the program and said the groups should have access to some frozen money. That order was put on hold during the appeal.

On April 16, 2025, the D.C. Circuit entered a partial administrative stay. A three-judge panel later ruled for EPA, but on December 17, 2025, the full court vacated that judgment, granted rehearing en banc and kept the partial stay in effect. The en banc court heard oral arguments on February 24, 2026, before issuing Tuesday’s divided decision.

Congress also repealed the statutory Greenhouse Gas Reduction Fund provision and rescinded unobligated funding in 2025. The court nevertheless continued to address the already awarded and obligated grants at the center of the case. That later legislation is one reason the ruling’s immediate effect on access to the money remains unsettled.

What happens next

The next major question is whether EPA files a request asking the Supreme Court to intervene. The D.C. Circuit or Supreme Court could then change, pause or otherwise affect the result, while the nonprofit groups continue seeking access to the funds.

The case has consequences beyond the named organizations. It tests how far a federal agency may go in canceling already awarded, congressionally funded grants after a change in administration, particularly when the agency relies on new policy priorities and oversight concerns rather than a proven violation of the grant terms.

The complaint and proposed consent decree were filed July 24, 2026, in the U.S. District Court for the Western District of Arkansas. The Justice Department is acting for the Environmental Protection Agency with the Arkansas Department of Energy & Environment’s Division of Environmental Quality.

The settlement is proposed, not a final court judgment. The DOJ’s consent-decree record lists a public-comment period from July 30 through Sept. 1, 2026. After that process, the court would have to approve and enter the decree before its obligations become effective.

What the government alleges

The complaint alleges violations of the federal Clean Air Act and the Arkansas Water and Air Pollution Control Act. Government filings describe alleged problems involving air-emission controls, leak detection, inspections and boiler testing at the Ashdown mill.

Among the allegations, the mill lacked required pollution controls for a brown stock washer system. The complaint also alleges that Domtar failed to meet inspection and leak-monitoring requirements, including a 53-day gap between inspections. The government says the mill failed to detect a leaking valve that emitted uncontrolled pollutants.

The government also alleges that performance testing for two boilers was inadequate. Because of monitoring and testing deficiencies, the Justice Department said the full extent of any excess hazardous-air-pollutant emissions is unknown.

The pollutants identified in government materials include hydrogen sulfide, volatile organic compounds, methanol, carbon monoxide, chlorine dioxide and hydrochloric acid. Hydrogen sulfide is associated with a rotten-egg odor and can harm human health at sufficient concentrations, but the filings do not establish a documented community injury from the alleged violations.

What the proposed decree would require

Separate from the civil penalty, the proposed decree would require at least $2.6 million in compliance and emissions-reduction work. The measures include installing proper pollution controls on the brown stock washer, capping valves, improving the biological wastewater-treatment system and expanding monitoring.

Domtar would also have to revise its leak-detection and repair procedures, obtain a third-party review of those procedures, complete required boiler testing and submit compliance reports. The practical focus is not only a financial penalty but also equipment and monitoring changes intended to detect and reduce emissions.

The $1.5 million penalty and the minimum $2.6 million in required work are separate obligations. The penalty would be paid to the United States and Arkansas under the proposed agreement, while the additional spending would fund injunctive-relief and mitigation measures at the facility.

What happens next

People who want to comment on the proposed decree must submit comments to the Justice Department by Sept. 1, 2026, according to the official case record and Federal Register notice.

The government may then ask the court to enter the decree after considering the public-comment process. The agreement would become effective only if the court approves it. The proposed terms also include a two-year compliance condition tied to possible termination of the decree.

For people who live near the Ashdown mill, the immediate practical issue is the comment period. The broader accountability question is whether the court approves a settlement that combines a monetary penalty with equipment, testing and monitoring changes intended to prevent future emissions problems.

Sources

• Justice Department settlement announcement
• Arkansas Advocate reporting

The EPA signed the proposal on July 1, 2026, and the rule was published in the Federal Register on July 7. Written comments are due Aug. 21, 2026, in docket EPA-HQ-OAR-2025-1212.

What would change

The proposal would revise 40 CFR 51.161, which currently sets federal minimums for public participation in state and local New Source Review programs. Under the proposal, those minimum public-participation requirements would no longer be required for minor NSR programs as a condition of approval in a state implementation plan.

State and local air agencies would instead decide whether, when and to what extent public participation is appropriate for a minor-source construction permit or a minor modification to an existing source. That could include decisions about public notice, access to permit information, comment periods and hearings.

Under the current federal baseline, the public generally must have access to relevant source information and the agency’s air-quality analysis, a 30-day period to submit comments and prominent notice in the affected area. The proposal would give air agencies discretion to change those procedures for minor NSR.

That does not mean public participation would disappear nationwide. States and local agencies could retain current requirements or adopt broader ones. If the rule is finalized and states revise their programs, residents could see greater differences from one jurisdiction to another.

What “minor” means

Minor New Source Review generally covers new or modified stationary sources that do not meet the regulatory thresholds for major-source permitting. A stationary source is a fixed facility or installation, such as a factory, power-related equipment or other industrial operation.

“Minor” is a regulatory classification, not a finding that a project has no local effect or that its emissions are trivial. Federal minor NSR rules do not establish one national list of every minor source or minor modification. State and local programs already differ in how they define and regulate sources below major-source thresholds.

The category can matter when communities are tracking smaller factories, gas-related facilities, backup generators or equipment associated with data centers. The proposal does not directly approve any particular project.

What would remain federally regulated

The EPA says the proposal would not change emissions standards, National Ambient Air Quality Standards or other applicable Clean Air Act requirements. A revised minor NSR program would still have to regulate construction and modifications as necessary to assure that national air-quality standards are achieved and maintained.

Major New Source Review would remain a separate, generally more prescriptive system. That includes Prevention of Significant Deterioration and nonattainment NSR requirements for major sources and major modifications.

The proposal also is not the same as changing Title V operating permits or National Environmental Policy Act review. Those are separate systems. The EPA said in the proposal that reducing public participation in a minor NSR authorization could affect how that authorization is later considered during some Title V oversight or petition processes.

Why the EPA says it is acting

The EPA describes the proposal as a way to recognize state and local discretion and reduce administrative burdens associated with a uniform federal process for minor sources. The agency argues that public participation can be tailored to local circumstances while substantive Clean Air Act requirements remain in place.

Supporters of the approach may view that flexibility as a way to avoid a one-size-fits-all process for projects below major-source thresholds. Critics may argue that shifting decisions about notice and hearings to individual agencies could make participation less predictable, reduce transparency or strain agencies with limited staff. Those are arguments about possible consequences, not established findings that the proposal would change air quality or approve projects.

What residents can do now

Nothing in the proposal immediately removes existing public-comment opportunities. It is a proposed rule, and the EPA must consider comments before deciding whether to revise, withdraw or finalize it. If finalized, states and local agencies would still need to use the state implementation-plan process to make any corresponding program changes.

Residents who want to comment should identify docket EPA-HQ-OAR-2025-1212 and submit written comments by Aug. 21, 2026. The Federal Register notice lists Regulations.gov as the EPA’s preferred submission method, along with other options.

People tracking a nearby project should also check the responsible state or local air agency. That agency handles the permit-specific notice, comment and hearing details, which may remain more extensive than the federal minimum or could change later if the proposal is finalized and the local program is revised.

The agreement, announced June 24, 2026, involves the Environmental Protection Agency, the Justice Department, the West Virginia Department of Environmental Protection and Chemours. EPA and DOJ describe it as the first comprehensive federal settlement resolving enforcement claims against a major PFAS manufacturer. The proposed consent decree was lodged in the U.S. District Court for the Southern District of West Virginia, but it is not final until the court approves it.

What the proposed agreement would require

The settlement would require Chemours to pay a $22.5 million civil penalty and carry out a government-supervised, multi-year PFAS mitigation program valued at $90 million.

It also includes estimated injunctive-relief costs. About $60 million would go toward pollution controls at Washington Works in West Virginia. Approximately $280 million would support treated or alternative drinking water for communities near Chemours facilities in West Virginia and New Jersey.

The more-than-$450 million figure is therefore a combined estimate of the civil penalty, mitigation funding and compliance-related work. It is not a promise that more than $450 million will be paid directly to residents or public water systems.

Chemours would test drinking water and provide treatment or alternative water to communities near its West Virginia and New Jersey facilities when they meet the agreement’s facility-specific requirements. The settlement does not mean every nearby resident or public water system automatically qualifies.

Facilities, rivers and alleged violations

The proposed settlement covers Washington Works in West Virginia; Fayetteville Works in North Carolina; and Chambers Works and Parlin in New Jersey.

Federal allegations describe PFAS releases into the Ohio River in West Virginia, the Cape Fear River in North Carolina and the Delaware River in New Jersey. The alleged violations involve the Clean Water Act, the Toxic Substances Control Act, the Resource Conservation and Recovery Act and the West Virginia Water Pollution Control Act.

The EPA summary says the allegations include discharges without required National Pollutant Discharge Elimination System permits, discharges that violated permit terms, failures to meet permit conditions, problems involving TSCA records and enclosed processes, and hazardous-waste acceptance or storage issues. These remain allegations addressed through a proposed consent decree rather than a final court judgment.

Controls Chemours would install

At Washington Works, the agreement calls for 14 projects to reduce PFAS in wastewater, stormwater and groundwater. Chemours would also be required to control GenX releases from each covered facility with an efficiency of at least 99%.

The company would implement enhanced leak-detection and repair programs, conduct engineering reviews to identify additional PFAS releases and certify compliance with hazardous-waste-storage requirements.

At Fayetteville Works, Chemours would evaluate options and install controls to reduce PFAS and other toxic releases based on recommendations from an independent engineering firm. The principal control and mitigation programs are expected to run for 15 years.

The agreement would allow Chemours to continue manufacturing some PFAS for critical commercial and military applications, including uses for which substitutes are not readily available. It is not a complete production ban.

Why residents should not assume they qualify for water service

The proposed drinking-water provisions are tied to communities near specific Chemours facilities in West Virginia and New Jersey. Eligibility and the form of assistance will depend on facility location, testing, implementation plans and the final court order.

Residents should watch for facility-specific notices about sampling, treatment systems or alternative-water supplies rather than assuming the settlement provides a uniform benefit throughout a state. The largest direct public-health component is the estimated $280 million for drinking-water protection near the West Virginia and New Jersey facilities.

Why the settlement is still pending

The public-comment period ran from June 29 through July 29, 2026. That period has closed, but the Southern District of West Virginia must still review the proposed consent decree and decide whether to approve it.

North Carolina officials criticized the agreement, arguing that it does not do enough for residents near Fayetteville Works. That criticism is an attributed position from state officials, not an adjudicated finding. Reuters reported that North Carolina had pursued a separate 2019 agreement with Chemours, while New Jersey announced a separate, broader environmental settlement involving Chemours, DuPont and Corteva in 2025.

The federal proposal also does not resolve every PFAS contamination claim or determine DuPont’s liability for past pollution. The covered facilities were previously owned by DuPont.

What to watch next

The next major checkpoint is court action on the consent decree. Residents, local officials and water providers should also watch for implementation plans, drinking-water test results, community notices, treatment-project schedules and details about how the $90 million mitigation program is allocated.

The interpretation appears in a July 16, 2026, memorandum to EPA regional administrators. It addresses a question that is becoming more important as data-center developers seek dedicated power for large artificial-intelligence facilities while grid connections can take years to arrange.

What EPA said

The Acid Rain Program was established under Title IV of the 1990 Clean Air Act Amendments. It includes sulfur dioxide and nitrogen oxide requirements for certain fossil-fuel-fired electricity-generating facilities.

EPA said its interpretation relies on the program’s definitions of a utility and a generator, along with language in the 1990 Department of Energy Form 860. That form covered facilities operated by electric utilities for electricity used primarily by the public.

Under EPA’s reading, a facility that produces electricity exclusively for a private consumer and is not connected to the larger electricity grid generally would not fall within the Acid Rain Program’s scope. The memorandum uses, as an example, a planned approximately 500-megawatt facility with simple-cycle natural-gas turbines and reciprocating engines serving an adjacent, privately owned data center.

The example is not an identified operating project, and the memorandum does not approve a particular developer or plant.

The memo is not a blanket Clean Air Act exemption

EPA expressly said the memorandum is not a final agency action and does not make a facility-specific determination. It also said the document does not address every situation in which the Acid Rain Program or other Clean Air Act requirements might apply.

The agency’s data-center resources page lists other potentially applicable requirements for stationary turbines and engines, including New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants. Depending on a project’s equipment, fuel, emissions and operating conditions, New Source Review, Title V or other Clean Air Act programs may also be relevant.

A later physical connection to the public grid could change the analysis. EPA said a facility that connects to the broader electricity system in the future may become subject to Acid Rain Program requirements, depending on the facts and applicable rules.

Why dedicated power is drawing attention

Data centers are seeking large and reliable power supplies as demand for artificial-intelligence computing expands. A private generation facility can be designed to serve one data center without relying on an immediate utility interconnection, but that approach raises questions about emissions, fuel use, backup systems, reliability and who is responsible for reviewing the project.

The EPA memorandum may narrow one federal compliance question for developers of fully islanded facilities. It does not determine whether a project can be built, how much pollution it may emit or whether it will receive an air permit.

State and local permits still matter

EPA said Acid Rain Program permitting is generally implemented through state air agencies under approved programs and advised sources to consult their state permitting authorities. EPA’s data-center materials also say state and local air agencies issue most air permits for data centers under programs that meet federal Clean Air Act requirements.

Those authorities may address construction, operating limits, emissions monitoring, pollution-control equipment, fuel choices and other conditions. Depending on the permit and the jurisdiction, public notice and comment may also be required.

Communities near proposed facilities should watch permit records for the project’s generation technology, projected emissions, operating hours, monitoring plans, control equipment and any proposed connection to the public grid.

The memorandum is part of a broader EPA effort to provide data-center developers and communities with Clean Air Act permitting information. Separate reporting by E&E News and KJZZ has described other elements of that effort, including a proposed federal change involving public-comment requirements for some minor-source air permits. That proposal is separate from the Acid Rain Program interpretation and is not a final rule.

What happens next

The most important next steps will come through facility-specific applications, state agency decisions and any public-comment procedures attached to those permits. Those records will show how regulators apply EPA’s interpretation to particular projects and what emissions controls and monitoring requirements remain.

Developers’ decisions about whether to remain fully islanded, connect later to the public grid or use different generation technologies could also affect the regulatory analysis. The July 16 memorandum provides EPA’s current interpretation, but it is not a final ruling on any individual plant and could receive further administrative or legal scrutiny.

For residents, the practical question is whether your local water provider—working with its state regulator—would pursue the extension and, if so, what additional interim steps and public notifications you should expect during the added time.

What EPA is proposing for PFOA and PFOS

EPA’s proposal would give certain public water systems a two-year compliance extension related to meeting enforceable drinking-water maximum contaminant levels (MCLs) for PFOA and PFOS. EPA frames this as a change in timing—not a removal of the underlying enforceable limits. The MCL targets remain the same during the extension period.

The key dates in this round

• July 7, 2026: EPA held a virtual public hearing on proposed PFAS-related Safe Drinking Water Act actions.
• July 20, 2026: Public comments are due.

After EPA reviews the comments, the agency could decide whether and how to finalize the proposal.

What changes during the extension period

If a system were eligible and pursued the extension, EPA’s materials describe additional obligations during the added time. The extension would not be a “pause” with no interim action.

According to EPA’s proposal materials, systems would be expected to focus on:

• Monitoring and reporting tied to the PFOA/PFOS requirements.
• Interim “control measures”—steps intended to reduce risk while the system works toward full compliance.
• Customer-facing notice steps so residents are informed about relevant conditions during the extension period.

EPA also says it would place extra emphasis on interim expectations when a system’s most recent results are at or above 12 ppt (as described in EPA’s supporting materials).

Who is involved (and what residents should watch for)

This is a federal rulemaking proposal, but implementation would run through EPA’s Safe Drinking Water Act framework and state “primacy” agencies. Local water systems would handle the day-to-day monitoring, reporting, and resident communications required by the extension terms if granted.

What to watch next:

• Utility notices and updates: Look for communications that reference interim control measures, monitoring timelines, or updated customer information.
• State agency messages: States may translate federal proposals into specific oversight expectations for systems in their jurisdiction.
• EPA’s final decision: Because this is not final, the compliance extension option could change after EPA considers public comments.

How the public can weigh in

EPA is accepting comments on the proposed compliance extension rule, with a July 20, 2026 deadline. EPA directs submissions through the method and public-comment instructions linked on its proposal page.

Residents don’t need technical details to participate. Comments can focus on whether the interim monitoring, control measures, and customer notification steps EPA proposes would adequately protect public health during any added compliance time.
