A caller trove of chemic shaper and US Environmental Protection Agency documents uncover an elaborate manufacture cognition that killed beardown regulations astir formaldehyde, a highly toxic carcinogen wide utilized successful mundane equipment from cosmetics to furnishings to trade supplies.
The Biden EPA successful precocious 2024 wished immoderate vulnerability to formaldehyde accrued nan consequence of crab and different wellness problems. The Trump EPA successful precocious 2025 moved to undo those findings and replace them pinch little protective figures.
The recently released documents show nan manufacture and nan Trump EPA’s scientific justification for weakening nan protections mostly relied on, aliases aligned with, a mini number of studies led by a chemic manufacture scientist, Rory Conolly, who based on that immoderate vulnerability to formaldehyde is safe. The Conolly studies were funded by chemic waste and acquisition groups. Between 2008-2024, nan EPA had concluded nan investigation was retired of day aliases unreliable, documents show.
Once nan Trump management took complete nan EPA, it changed formaldehyde consequence levels to align pinch nan level Conolly recovered was safe. It relied successful portion connected his assessments, constricted information from different researchers, aliases studies nan EPA antecedently recovered to beryllium retired of date. Advocates opportunity nan documents show nan Trump EPA often “cherry picked” data.
The documents, obtained via a Freedom of Information Act petition by nan Environmental Defense Fund (EDF), a non-profit, besides show an different three-day gathering successful 2023 among nan EPA and apical formaldehyde producers, users and waste and acquisition groups. Among nan presenters was Conolly.
Much of manufacture and nan Trump EPA claims and justification are “based connected what Conolly did”, said Maria Doa, a erstwhile EPA intelligence now pinch EDF. The documents radiance a ray connected nan ferocity pinch which nan powerful chemic lobby attacks regulations to protect its profits.
“The bottommost statement is money – and that they want constricted regulations connected nan chemicals they are making,” Doa told nan Guardian.
The EPA said successful a connection that it changed nan levels because nan “Biden Administration utilized flawed analyses successful its consequence appraisal of formaldehyde”. The caller appraisal takes into relationship a wider scope of views, and “strengthens protections by relying connected golden modular science”, a spokesperson said.
Chemical makers annually nutrient up to 5bn pounds of formaldehyde, a pungent colorless state astatine room temperature. Companies adhd it to user products because it’s an effective preservative, binder, anti-fungal aliases it is utilized successful glue.
The manufacture has, for decades, waged an aggravated warfare against formaldehyde regulations. But nan latest salvo is bigger than conscionable formaldehyde, said Erik Olson, a elder advisor pinch nan Natural Resources Defense Council Action Fund who has lobbied connected toxic chemic issues.
The EPA has established a pathway that could beryllium utilized to re-evaluate and weaken regulations astir each carcinogen, Olson said, and that could lead to a wide summation successful nan public’s vulnerability to toxic chemicals.
“We perceive astir making America patient again, but present we person an illustration of nan EPA undermining decades of knowing astir a cancer-causing chemic for which location is nary safe level of exposure,” Olson said.
“Watch out. There are a batch of different carcinogens that manufacture wants to prime off.”
‘The full point is crazy’
The EPA during nan Biden years conducted a multiyear, systematic reappraisal of nan latest formaldehyde subject from its ain researchers, independent scientists and immoderate industry-affiliated labs. This was its justification for concluding that nan safe level of vulnerability to formaldehyde via inhalation is zero.
The Trump EPA replaced that uncovering pinch nan declare that crab only becomes a consequence astatine a higher “threshold”. The Trump EPA and Conolly recovered that nan period is .3 parts per cardinal (ppm), nan aforesaid level astatine which vulnerability to nan formaldehyde causes sensory irritation. They declare protecting against irritation will besides protect against cancer.
That conclusion contradicts a overmuch broader assemblage of investigation that recovered crab consequence astatine a little level than nan irritation threshold.
“The full point is crazy,” Doa said.
Conolly’s studies from complete nan past 20 years are many times cited successful manufacture documents obtained via FOIA, and are indirectly referenced by nan Trump EPA successful its justification for nan changes.
In 2024, Conolly gave a presentation to nan EPA subject advisory committee connected chemicals. SACC concluded that immoderate level of vulnerability to formaldehyde accrued crab risk, though Conolly disagreed pinch nan broader committee. In precocious 2025, nan Trump EPA published successful nan Federal Register its projected caller rules that would reverse nan Biden regulations. It wrote that “the mostly of nan accusation presented [by SACC]”, concluded nan .3 ppm period was astir appropriate, successful portion referencing Conolly’s work.
The Trump EPA wrote: “.3 ppm is protective of effects for each durations, including cancer.” Doa said nan EPA “cherry picked” dissenting opinions, including Conolly’s.
The recently released documents show nan EPA antecedently recovered Conolly’s studies were retired of date, aliases discredited them. The agency wrote successful 2024 that his investigation contained “model uncertainties that were excessively ample to usage successful consequence assessments”.
In a connection to nan Guardian, Connolly said he was not “impressed” pinch nan earlier EPA critiques, and that it did not look that nan agency thoroughly considered a 2023 update to his investigation that he said addressed their concerns.
Connolly said nan Trump EPA’s changes to formaldehyde consequence levels were “consistent with” his investigation and it is unclear which subject was utilized to warrant nan changes.
“Yes, I work together that formaldehyde should beryllium regulated on nan lines of nan existent EPA position, but I do person to wonderment really they sewage there,” Conolly said. The EPA besides heavy relied connected immoderate quality studies from arsenic acold backmost arsenic 1987 to create their threshold.
Conolly’s early papers were money by nan Chemical Industry Institute of Technology, a waste and acquisition group, while his 2023 insubstantial was funded by nan American Chemistry Council. The American Chemistry Council’s Julianne Ogden sent an email to nan EPA soon aft nan February 2023 gathering pushing industry’s statement that .3 ppm of formaldehyde successful nan aerial is safe.
Conolly downplayed nan power connected his findings, noting that he has worked for nan subject and academia.
“In evaluating science, what matters is nan value of nan science,” Conolly said. “Saying that subject is nary bully because it was manufacture funded is simply a cop-out.”
Conflicts of liking questions
The aforesaid manufacture leaders carrying retired nan onslaught connected nan regulations successful 2022-2024 took complete nan EPA successful 2025, documents show. They quickly went to activity dismantling nan formaldehyde regulations.
Among them are Nancy Beck and Lynn Dekleva, erstwhile apical American Chemistry Council officials now successful activity astatine nan EPA chemic information office. Dekleva besides spent 32 years astatine DuPont.
“The [formaldehyde] regulatory changes are happening astatine Beck and Dekleva’s direction, pinch their nonstop oversight and supervision, and pinch their support of nan last language,” said Kyla Bennett, a erstwhile EPA intelligence now pinch nan Public Employees For Responsibility non-profit. It useful pinch whistleblowers and EPA labor to expose agency wrongdoing.
The manufacture attacks focused connected 2 cardinal pieces of subject underpinning nan beardown formaldehyde regulations.
The EPA’s Integrated Risk Information System (IRIS) is nan agency that wished that nary level of vulnerability to formaldehyde is safe. Until nan 2nd Trump administration, IRIS was among nan astir politically insulated offices successful nan EPA, Bennett said. It intends to do “pure science” that is not influenced by nan governmental winds, Bennett added.
IRIS’s conclusions are reviewed by nan National Academy of Science Engineering and Medicine (NASEM). Abraham Lincoln established NASEM to supply independent technological guidance to national agencies and to reappraisal their work. It is besides politically insulated and composed of galore of nan nation’s foremost independent scientists, academics and manufacture players.
A NASEM committee wrote successful 2024 that it “concurred” pinch IRIS’s conclusion that nary level of formaldehyde vulnerability was safe, uncovering it “appropriate and acceptable”. The EPA’s findings were “consistent pinch EPA’s state-of-practice methods”.
Documents show galore examples of nan manufacture taking purpose astatine NASEM’s and IRIS’s findings. At nan February 2023 meeting, nan American Chemistry Council based on that location was robust technological statement that IRIS’s appraisal contained “deficiencies”.
This straight contradicted what NASEM wrote, Doa said. And she recovered important conflicts of liking successful 11 of nan 15 scientists manufacture cited successful its presentation. Among them is Harvey Checkoway, who receives investigation backing from nan American Chemistry Council, Aluminum Company of America, Dupont, Materion and Monsanto, among different manufacture clients.
Checkoway did not respond to nan Guardian’s petition for comment.
In different cases, nan manufacture again “cherry-picked” data, Doa said, noting a 2022 Dekleva missive to nan EPA, while Dekleva was still astatine nan American Chemistry Council. It claimed IRIS “implied” that .3 ppm was a safe level of exposure, which Doa said overtly contradicts IRIS’s findings.
Dekleva many times cites successful nan missive Conolly’s 15-year-old subject that nan agency had since recovered was retired of day aliases excessively uncertain. In its justification for undoing nan rules that were published connected nan Federal Register, nan Trump EPA wrote that it “revisited” nan IRIS appraisal and is “no longer relying connected nan EPA IRIS”.
The distortion of NASEM’s conclusion besides appeared successful nan Federal Register and EPA’s December 2025 announcement. It wrote that it had reviewed NASEM and different technological bodies’ comments, and was “following their recommendations and focusing connected nan science”.
Olson is calling connected Congress to analyse these types of issues and nan broader manufacture takeover of nan EPA.
“It sounds for illustration insider baseball, but it has very existent implications for group exposed to these chemicals and for people’s pocketbooks,” Olson said. “We’re going to salary for this done nan chemoreceptor for our taxes and security bills.”
