This “Climate-Friendly” Fuel Comes With an Astronomical Cancer Risk
Sharon Lerner | February 23, 2023 | ProPublica
The Environmental Protection Agency recently gave a Chevron refinery the green light to create fuel from discarded plastics as part of a “climate-friendly” initiative to boost alternatives to petroleum. But, according to agency records obtained by ProPublica and The Guardian, the production of one of the fuels could emit air pollution that is so toxic, 1 out of 4 people exposed to it over a lifetime could get cancer.
“That kind of risk is obscene,” said Linda Birnbaum, former head of the National Institute of Environmental Health Sciences. “You can’t let that get out.”
That risk is 250,000 times greater than the level usually considered acceptable by the EPA division that approves new chemicals. Chevron hasn’t started making this jet fuel yet, the EPA said. When the company does, the cancer burden will disproportionately fall on people who have low incomes and are Black because of the population that lives within 3 miles of the refinery in Pascagoula, Mississippi.
ProPublica and The Guardian asked Maria Doa, a scientist who worked at the EPA for 30 years, to review the document laying out the risk. Doa, who once ran the division that managed the risks posed by chemicals, was so alarmed by the cancer threat that she initially assumed it was a typographical error. “EPA should not allow these risks in Pascagoula or anywhere,” said Doa, who now is the senior director of chemical policy at Environmental Defense Fund.
In response to questions from ProPublica and The Guardian, an EPA spokesperson wrote that the agency’s lifetime cancer risk calculation is “a very conservative estimate with ‘high uncertainty,’” meaning the government erred on the side of caution in calculating such a high risk.
Under federal law, the EPA can’t approve new chemicals with serious health or environmental risks unless it comes up with ways to minimize the dangers. And if the EPA is unsure, the law allows the agency to order lab testing that would clarify the potential health and environmental harms. In the case of these new plastic-based fuels, the agency didn’t do either of those things. In approving the jet fuel, the EPA didn’t require any lab tests, air monitoring or controls that would reduce the release of the cancer-causing pollutants or people’s exposure to them.
In January 2022, the EPA announced the initiative to streamline the approval of petroleum alternatives in what a press release called “part of the Biden-Harris Administration’s actions to confront the climate crisis.” While the program cleared new fuels made from plants, it also signed off on fuels made from plastics even though they themselves are petroleum-based and contribute to the release of planet-warming greenhouse gases.
Although there’s no mention of discarded plastics in the press release or on the EPA website’s description of the program, an agency spokesperson told ProPublica and The Guardian that it allows them because the initiative also covers fuels made from waste. The spokesperson said that 16 of the 34 fuels the program approved so far are made from waste. She would not say how many of those are made from plastic and stated that such information was confidential.
All of the waste-based fuels are the subject of consent orders, documents the EPA issues when it finds that new chemicals or mixtures may pose an “unreasonable risk” to human health or the environment. The documents specify those risks and the agency’s instructions for mitigating them.
But the agency won’t turn over these records or reveal information about the waste-based fuels, even their names and chemical structures. Without those basic details, it’s nearly impossible to determine which of the thousands of consent orders on the EPA website apply to this program. In keeping this information secret, the EPA cited a legal provision that allows companies to claim as confidential any information that would give their competitors an advantage in the marketplace.
Nevertheless, ProPublica and The Guardian did obtain one consent order that covers a dozen Chevron fuels made from plastics that were reviewed under the program. Although the EPA had blacked out sections, including the chemicals’ names, that document showed that the fuels that Chevron plans to make at its Pascagoula refinery present serious health risks, including developmental problems in children and cancer and harm to the nervous system, reproductive system, liver, kidney, blood and spleen.
