Endangerment Finding Litigation Update

From THE MANHATTAN CONTRARIAN

Francis Menton

On February 13 this year, the federal EPA rescinded one of its regulatory actions known as the “Endangerment Finding.” (EF). The EF, originally adopted in 2009 early in the Obama administration, was likely the single most costly and destructive regulatory action ever to spring forth from the administrative state. The EF became the fundamental underpinning for all the subsequent regulations that sought to restrict and ultimately ban use of fossil fuels in the economy — everything from regulations seeking to force closure of power plants, to efforts to mandate only electric cars, to restrictions on drilling and pipelines, and much, much more. The Trump administration is now systematically dismantling all those regulatory wrecking balls.

But the opposition has not been idle. Once the rescission became final, the Climate Blob immediately sprang into action with a barrage of lawfare. The first litigation challenging rescission of the EF was filed in the D.C. Circuit on February 18. Over the succeeding several weeks, dozens of additional petitioners joined the fray. Since then, however, the case, although pending, has not moved quickly. I last provided an update in this post from June 8.

For discerning observers of this process, here is the key question of interest: Will the D.C. Circuit schedule this matter to move at a pace consistent with enabling final review of EPA’s action to be concluded by the Supreme Court before the end of President Trump’s term? Or, alternatively, does the D.C. Circuit intend to stall resolution of the case in order to potentially give a new Democratic administration a chance to come into office in early 2029 and do another 180 degree course reversal? At this writing, it is still too early to know fully how the D.C. Circuit will deal with this issue. However, from evidence so far, it looks like those betting the court will slow walk the case have the odds on their side.

The first indication that the court is not in a hurry came in a scheduling Order on April 22, setting dates for the next events in the case. April 22, about two months after the case had begun, would have been a normal time for the court to set deadlines for the parties to file their briefs on the merits. But this Order did not do that. Instead, it only set deadlines for the making of certain motions — “procedural” motions by May 20, and “dispositive” motions by June 4. The court in that Order also specifically declined a request to direct the parties to propose deadlines for the main briefing, and stated: “any order directing the parties to file briefing proposals will be entered after any procedural or dispositive motions are resolved.” You might say that the court was sending a clear signal that parties could file any crazy motions that they could think of, and thereby get several months of free delay in the case.

And indeed the May 20 deadline did bring two motions that you might think are completely ridiculous — until you realize that the real point is probably to buy a few months of delay. One of those motions requested a “stay” of the rescission of the EF. I covered that one in my June 8 post, and won’t repeat that here, except for this great quote on the claimed basis for the stay:

The Repeal Rule substantially burdens Petitioners Elena, J.K., M.D., and E.S.’s sincerely held religious beliefs. . . . Petitioners E.S. and J.K. are observant Jews whose religion requires them to walk to synagogue on the Sabbath. . . . M.D. is an observant Muslim whose religion requires her to fast during Ramadan. . . . Each Sabbath that is made too hot for E.S. and J.K. to walk safely to synagogue, and each day of Ramadan that is made too hot for M.D. to safely fast and wear hijab, is a day they are prevented from observing important requirements of their religions.

The second “procedural” motion filed on May 20 styled itself as a “motion to complete the record.” That sounds minor and technical. Such motions are not uncommon, and often just ask to add one or a few documents that may have been omitted from a record, perhaps by mistake. But of course this one is not like that, and rather is a very strategic effort to throw a monkey wrench into the whole process.

For starters, check out this list of parties who signed on to this motion:

Alliance of Nurses for Healthy Environments, American Lung Association, American Public Health Association, Center for Biological Diversity, Center for Community Action and Environmental Justice, Clean Air Council, Clean Wisconsin, Conservation Law Foundation, Environmental Defense Fund, Environmental Law & Policy Center, Friends of the Earth, Natural Resources Defense Council, Inc., Physicians for Social Responsibility, Public Citizen, Rio Grande International Study Center, Sierra Club and Union of Concerned Scientists in 26-1037, ZETA in 26-1039, Service Employees International Union in 26-1051, City and County of Denver, Colorado, City and County of San Francisco, California, City of Albuquerque, New Mexico, City of Boston, Massachusetts, City of Chicago, Illinois, City of Cleveland, Ohio, City of Columbus, Ohio, City of Los Angeles, California, City of New York, New York, Commonwealth of Massachusetts, Commonwealth of Virginia, DC, Harris County, Texas, Martin Luther King Jr. County, Washington, Santa Clara County, California, Josh Shapiro, State of Arizona, State of California, State of Colorado, State of Connecticut, State of Delaware, State of Hawaii, State of Illinois, State of Maine, State of Maryland, State of Michigan, State of Minnesota, State of Nevada, State of New Jersey, State of New Mexico, State of New York, State of North Carolina, State of Oregon, State of Rhode Island, State of Vermont, State of Washington, State of Wisconsin and Virgin Islands in 26-1061, Bay Area Air Quality Management District in 26-1090.

It’s an entire who’s who of environmental NGOs and blue states.

So what is the big complaint? When an agency like EPA rescinds a regulation like the EF, one of the things it needs to do is take public comments and respond to the comments. That process is the main reason why there was a nearly thirteen-month period between President Trump’s Executive Order directing EPA to reconsider the EF (January 20, 2025) and EPA’s final rescission of the EF (February 13, 2026). The public comment period here extended from the end of July through September 22, 2025. A big part of the game of the environmental NGOs is to gum up the process by orchestrating the submission of so many tens or hundreds of thousands of comments as to make it next to impossible for the agency to respond thoroughly within any reasonable time frame. Here, many tens of thousands of comments were received. When EPA issued the final rule, it also issued a document responding to the comments. That document was 1,794 pages long! Here is the gripe from the petitioners’ motion:

EPA included a version of EPA’s Response-to-Comments document that was created some 10 hours after Administrator Zeldin announced that the Rescission was “signed, sealed, delivered.” When asked if the document was supplemented or modified after the Administrator signed the final rule, the agency refused to say—suggesting the document reflects post-decisional additions of or edits to EPA’s responses.

Nefarious! With trillions of dollars of economic activity in the balance, this case is getting held up by a demand to fly-speck the final edits of the nearly 2000 page response-to-comments document to see if anything embarrassing can be found.

The government submitted its response to this motion on June 12. Here is the gist of the response on that main point:

[T]he Response to Comments—finalized, as required by the Clean Air Act, on the “date” that the rule was promulgated—is properly part of the record. 42 U.S.C. § 7607(d)(6)(C). In this Circuit, as in everyday speech, “date” means date. The Court should reject Petitioners’ invitation to rewrite the statute to require the Response to Comments to be finalized, docketed, and time-stamped at either the hour or the exact moment of promulgation.

And then the moving parties got to submit a Reply on this motion, which came in on June 29.

So here we are on July 21, more than five months since the case began. The court has not issued a decision on either of these preposterous “procedural” motions. And while we await those decisions, there is no scheduling order as to when the real briefing in the case will begin or end.

If you are a betting person, you will likely bet that the D.C. Circuit will rule against the Trump administration on the merits of this case. After all, the climate scam is a central tenet of Democratic Party orthodoxy, and 7 of the 11 active judges on the D.C. Circuit are reliable partisan Democrats. But the Supreme Court is likely to support the position of the Trump administration. The case needs to reach final resolution in the D.C. Circuit by, at the absolute latest, some time in late 2027, in order for the case to reach resolution in the Supreme Court before President Trump leaves office in January 2029. (Some Supreme Court specialists may say that the drop dead date for D.C. Circuit resolution is even earlier.). Will the D.C. Circuit game the scheduling to make this case take that long to resolve? Place your bets!

This is becoming a pattern. The deep state delays cases that they know that they can’t win, hoping that the plaintiff either dies, or leaves office.

Their argument will probably be that they’re U.S. citizens (don’t know if they are or not) and grew up and acclimatized to the weather in the U.S. Therefore, it’s their legal right to demand that the government provided them with the comfortable weather they deserve.

Recently, a the chief justice of the Hawaiian supreme Court declared that it was absurd that the US SC had rejected a law that the legislature had passed and the people wanted. Also he was instructing the state courts to ignore any ruling from the Robert’s court.

The idea that a judge in a state’s highest court doesn’t realize that the constitution is not something that can be ignored at will is something only the far left could come up with.

Nationally, the EPA Endangerment Finding only applied to the 340 million that live in the USA, i.e., it applied to only 4% of the 8 billion people on the planet.
·       The federal spending surrounding the Endangerment Species Act (ESA) ballooned to over $1.135 billion a year – a staggering sum largely hidden from the public view
 

Shockingly, Pew Research Center shows about 70% of the 8 billion on this planet, or almost 6 billion, are living on less than $10/day and have yet to join the industrial revolution!

 

  • For those almost 6 billion living in poverty on this planet, the worse form of air pollution is indoor air pollution, caused by poor people burning coal, wood, dung, candles, and paraffin in badly ventilated shacks, often without chimneys.
  • Worldwide, more than 3 million people in poverty die prematurely each year from illnesses caused by indoor air pollution. These deaths are primarily linked to cooking with polluting fuels, resulting in respiratory infections, strokes, heart disease, and lung cancer.

Even the native Americans ‘knew’ about ‘chimneys’. Examples include plains Indian buffalo hide traverse teepee top flap rain adjustable openings, and Eskimo igloo apex winter fist holes. So there is ‘no excuse’ for rest of world not also figuring out ‘chimneys’ despite their poor fuel use. For Plains Indians, it was dried buffalo dung. For Eskimos, it was seal blubber.

It may be true that there are millions of poverty related excess ‘indoor cooking’ related deaths. Have not researched it, nor will. I think poverty, rather than chimney, related.

The well documented court ‘delay’ Lawfare strategy on the EF repeal is, IMO, misguided and going to fail. There are two separate reasons having little to do with the transparently obvious and pathetic Lawfare delay strategy documented in this guest post. Both remind me of the old trial lawyer adage: If the facts are against you, pound the law. If the law is against you, pound the facts. If both are against you, pound the podium. This EF repeal lawfare is mostly podium pounding.

  1. SCOTUS composition is unlikely to soon change in libs favor even after 47 leaves office even IF Dems win in 28. There is no indication that the two oldest conservatives—Thomas and Alito—are infirm or in ill health. There are indications that Sotomeyer (overweight diabetic) might be.
  2. I do not think Dems can win the White House in 28 despite their present TDS hopes. 2 subreasons. First, 47’s economic initiatives have yet to take full effect—but they will by Nov 27. Second, Dems have gone nutso DSA, and have NO potential presidential candidate of standing to even remotely challenge a Vance/Rubio or Rubio/Vance GOP team. Newsom ruined California. Harris has become a word salad joke. Pritzger doesn’t even manage his IL mess— see Chicago!

The only reason the DSA is growing in influence is because everything they do is anti-Trump, and a lot of the public hates Trump. That public hate will dissipate for the 2028 election and the Dems haven’t done anything to prepare for a post-Trump world.

I wish I were as optimistic as you, but the out of power party usually wins the midterms and I don’t think Vance or Rubio will gain traction in 28. And I don’t think anyone can solve the intractable economic and social problems afflicting the USA, ie, debt and inflation, divorce and low fertility.

I fear the Dems will rush back into power and on climate activism pretend the last two years didn’t happen, and we need to be ready for it.

Are Democrat climate and energy policies hostile to capital-intensive fossil-fuel infrastructure? Yes, that’s what the Endangerment Finding is all about: Killing FF and the associated infrastructure and at the same time refusing to endorse nuclear, including SMR.

Does the resulting policy instability reduce investment and industrial capacity?  Yes, except for subsidized guaranteed by statute income producing essentially worthless solar and wind.

Pipelines as a case in point
From an investor’s perspective, a pipeline is unusually sensitive to political durability because:

  • Development timelines are long.
  • Up-front capital costs are large.
  • Regulatory approvals are numerous.
  • Returns are realized over decades, not years.

That means policy uncertainty can matter almost as much as the underlying economics. —Keystone XL and Dakota Access—became symbols of that broader durability problem.

  • Keystone XL became a long-running political and legal battle that spanned multiple administrations and regulatory decisions.
  • Dakota Access was subject to extensive litigation, including disputes over environmental review requirements.

Regardless of one’s view of the merits, those episodes demonstrated that major energy infrastructure projects can remain exposed to political and legal risk long after sponsors think they have secured the necessary approvals.

The “durability discount”
The primary cost imposed by policy instability is not necessarily the loss of individual projects. It is the increase in the discount rate investors apply to future projects.
Suppose a company believes:

  • A pipeline permit is valid today.
  • A future administration may revisit the project.
  • Litigation could continue for years.

Even if the project ultimately succeeds, the uncertainty itself raises the required return.

For long-lived infrastructure, durability may be more important than the immediate policy outcome itself. A favorable policy that is likely to be reversed in four years can have surprisingly little investment value because firms know it may not last. Should anyone be surprised that long term heavy industry investment in China has more ‘durability” than in the U.S?

The Biden EPA’s Clean Power Plan 2.0 (CPP 2.0) published in the summer of 2024 was designed specifically to create regulatory uncertainty in ways which would make long-term investments in fossil-fueled power plants a very risky business indeed.

The 2024 CPP 2.0 was published under the protective umbrella of the 2022 Investment Recovery Act (IRA) which contains text that specifically identifies CO2 and methane as atmospheric pollutants. That text remains on the legislative books.

Here are some relevant points to whet a public policy wonk’s appetite for the gory details:

— The Obama EPA’s Clean Power Plan 1.0 from 2013 used a Clean Air Act Section 111 process which does not require an endangerment finding to become operative. However, CPP 1.0 did violate the Major Questions Doctrine which made it vulnerable to lawsuits.

— The authors of the 2022 Inflation Reduction Act state unequivocally that the IRA gives authority to the EPA to regulate carbon emissions as pollutants, thus overcoming the Major Questions Doctrine.

— Before it was cancelled by Trump’s EPA in 2025, the Biden EPA’s Clean Power Plan 2.0 from 2024 relied on the 2022 IRA for Congressional authorization. Like 2013’s CPP 1.0, 2024’s CPP 2.0 also invoked a CAA Section 111 process, one which does not require an endangerment finding to become operative.

— There is every possibility that the Democrats will be in full control of Congress in 2027. If that happens, they will most certainly pass legislation which explicitly and unequivocally directs the EPA to regulate atmospheric carbon emissions as pollutants, and which supplies funding to the EPA to do so.

— The courts will not spend time working on current litigation involving the 2009 Endangerment Finding when there is every possibility the issue will be quickly rendered moot by a new Congress.

As long as Congressional legislation is on the books which directly identifies carbon emissions as atmospheric pollutants, which 2022’s IRA does, the major questions doctrine has not been violated.

Furthermore, if the 2022 IRA remains active, the EPA doesn’t need an endangerment finding to legally regulate CO2 and other carbon compounds if it employs a CAA Section 111 process.

As things stand today in the summer of 2026, here is what it all boils down to …. the carbon regulation landscape has moved on from the mid-2000’s requirement to have a technically legal mechanism available in the form of an endangerment finding and subsequent NAAQS for carbon.

And so either fighting the 2009 Endangerment Finding in court, or else defending it in court — each of these two opposing actions are now mere kabuke theater.
