Public health groups are "fully committed to taking all steps available to assure that the Inhance fluorination no longer produces dangerous PFAS which put workers, consumers, and communities at risk."
As public health experts raise alarm over the prevalence of highly toxic "forever chemicals," as per- and polyfluoroalkyl substances or PFAS are commonly known, one nonprofit investigative journalism outlet warned Saturday that a recent ruling could further tie up the regulatory process for the chemicals and other harmful substances.
"This ruling is likely to impede already excruciatingly slow efforts to regulate the presence of health harming chemicals in products people use in every part of their lives," said Watershed Investigations of a decision handed down earlier this month by the right-wing Fifth Circuit Court of Appeals in New Orleans.
The case is one of several involving Inhance Technologies, a Houston-based company that manufactures an estimated 200 million plastic containers each year using the fluorination process, which creates perfluorooctanoic acid (PFOA), a toxic PFAS compound.
In 2020, the Environmental Protection Agency (EPA) began requiring companies to submit notices regarding "significant new uses" of PFAS under Section 5 of the Toxic Substances Control Act (TSCA), as officials identified the chemicals as an "urgent public health and environmental issue" due to their links to cancer, liver and kidney disease, reproductive harms, and other serious health problems.
The agency found that PFAS were leaching into pesticides held in containers produced by Inhance.
In December, the agency prohibited Inhance from using the fluorination process because it had identified PFAS as an "unavoidable aspect" of its operations. Inhance sued the EPA soon after.
Inhance said that ending its fluorination practices would ultimately force the company to shut down and fought the EPA's order, arguing that it had created its plastic containers in the same way for decades, and therefore was not subject to the TSCA provision regarding "significant new use."
The EPA argued it only became aware of Inhance's process in 2020, but the conservative court disagreed that it could regulate the company under the "new use" rule—even as the judges acknowledged the company's products are harmful.
"The court did not dispute EPA's underlying decision that this is a danger to human health, what they did was say it's not a new use, which I think is wrong... but this case isn't over by any stretch," Kyla Bennett, a former EPA official who is now director of science policy for Public Employees for Environmental Responsibility (PEER), told The Guardian Saturday.
The judges said the EPA would have to regulate Inhance's containers under Section 6 of the TSCA, which it said requires the EPA to take into account the economic impact any regulations would have on Inhance.
PEER noted that Section 6 also states that health risks should be considered.
"The court erroneously limits EPA's authority to issue significant new use rules (SNURs) under the TSCA, seriously weakening this important tool for managing chemical risks to health and the environment which has been a mainstay of the TSCA program since the law's enactment in 1976," the group said.
Another case is playing out in the U.S. District Court for the Eastern District of Pennsylvania, where the EPA sued Inhance in 2022 for violating the TSCA. The Center for Environmental Health and PEER also took legal action against Inhance for the same reason, and against the EPA last month for withholding test data regarding PFAS in plastic containers.
"There are several paths forward," said PEER, "and our groups are fully committed to taking all steps available to assure that the Inhance fluorination no longer produces dangerous PFAS which put workers, consumers, and communities at risk."
"By sitting on this critical information, EPA is advancing the private interests of a corporate violator and shirking its public health responsibilities," said one plaintiff's attorney.
A federal lawsuit filed Thursday by a pair of environmental advocacy groups accuses the U.S. Environmental Protection Agency of "wrongfully withholding test data and other vital information" regarding the presence of so-called "forever chemicals" in millions of fluorinated plastic containers.
The lawsuit—filed in the U.S. District Court in Washington, D.C. by Public Employees for Environmental Responsibility (PEER) and the Center for Environmental Health (CEH)—argues that the EPA is violating Toxic Substances Control Act (TSCA) disclosure requirements by improperly classifying health and safety data as trade secrets.
Referring to per- and polyfluoroalkyl substances—commonly known as forever chemicals because they do not biodegrade and accumulate in the human body—the suit also accuses the EPA of "denying the public access to the results of testing showing the levels of PFAS in fluorinated plastic containers and their contents along with the identities of the products in which these toxic materials are present."
PEER and CEH said that after they filed a Freedom of Information Act request "for documents shedding light on the health risks associated with PFAS in fluorinated containers," the EPA granted trade secret protection sought by Inhance Technologies, LLC.
Fluorination involves the high-temperature application of fluorine gas to plastic containers to make them more resistant to discoloration and permeation by solvents.
As PEER explained:
PFAS chemicals are formed during the fluorination of high-density polyethylene plastic containers by Inhance Technologies, LLC of Houston, Texas. Inhance is the sole U.S. company conducting this type of fluorination. Studies by EPA, independent researchers, and Inhance itself show that PFAS leaches from the walls of containers into their contents, thus exposing millions of people to PFAS without their knowledge...
Inhance fluorinates 200 million containers a year which are used to package diverse products ranging from fuels to foodstuffs, cosmetics, and cleaning products which consumers and workers use on a daily basis.
"EPA has found that these containers constitute a public health threat, a long-awaited determination that also should encompass the public's right to know," CEH counsel Bob Sussman, who is also a former senior EPA official, said in a statement announcing the new lawsuit.
Used in a broad range of products from clothing to nonstick cookware to firefighting foam, PFAS is linked to cancers of the kidneys and testicles, low infant weight, suppressed immune function, and other adverse health effects. It is found in the blood of 99% of Americans and a similar percentage of people around the world.
"Given the unquestionably major public health stakes, EPA should be stepping up and maximizing access to health and safety data, but the agency is disclosing vital information only grudgingly and with lingering secrecy even though disclosure is mandated by TSCA," Sussman lamented.
Colleen Teubner, PEER's litigation and policy attorney, asserted that "the cloak of confidential business information cannot be used to hide health and safety studies as EPA is currently doing."
"By sitting on this critical information, EPA is advancing the private interests of a corporate violator and shirking its public health responsibilities," she added.
The new lawsuit follows a December 2022 court filing by PEER and CEH seeking to stop Inhance from generating forever chemicals during the manufacture of plastic containers.
Thousands of PFAS-related lawsuits have been launched in U.S. courts over recent decades.
