The Trump administration on Friday moved to roll back Biden-era limits on emissions of ethylene oxide, a cancer-causing chemical often used in the sterilization of medical devices.

The Environmental Protection Agency said repealing the rules, which fall under the National Emission Standards for Hazardous Air Pollutants, would “safeguard the supply of essential medical equipment” — saving approximately $630 million for companies over 20 years. California is home to about a dozen such facilities.

The government said the emissions are part and parcel of protecting people from “lethal or significantly debilitating infections that would result without properly sterilized medical equipment.”

“The Trump EPA is committed to ensuring life-saving medical devices remain available for the critical care of America’s children, elderly, and all patients without unnecessary exposure to communities,” EPA Administrator Lee Zeldin said in a statement.

An estimated 50% of sterile medical devices in the U.S. are treated with ethylene oxide, or EtO, particularly those that can’t be cleaned using steam or radiation. The colorless gas is also used to make chemicals found in products such as antifreeze, detergents, plastics and adhesives.

But EtO poses health risks. Short-term exposure by inhalation can cause headaches, dizziness, nausea, fatigue respiratory irritation and other adverse health effects, according to the federal Agency for Toxic Substances and Disease Registry.

Longer-term exposure increases the risk of cancers of the white blood cells, such as non-Hodgkin’s lymphoma, as well as breast cancer. A now-deleted page from the EPA’s website stated, “EtO is a human carcinogen. It causes cancer in humans.”

Friday’s proposal specifically targets updated rules for EtO emissions that were passed by the Biden administration in 2024 following pressure from environmental justice groups, particularly those in Louisiana’s heavily industrialized “Cancer Alley.” The change sought to reduce the amount of EtO released from commercial sterilizers by 90% and lessen the hazards for nearby communities.

The tighter rules were in part based on EPA’s own scientific study that found it to be 60 times more carcinogenic than previously thought, which the agency now says should be reassessed.

If finalized, the plan would give facilities the choice between installing continuous real-time monitoring systems for EtO emissions or complying with modified pollution control requirements at facilities that emit more than 10 tons a year, the EPA said.

The proposal follows other moves by the Trump administration to rescind regulations that it says are burdensome and costly for industries, such as those governing emissions from coal power plants. Last month, the EPA repealed the endangerment finding, which affirmed the dangers of greenhouse gas emissions and underpinned the agency’s ability to regulate those emissions from vehicles.

The action around ethylene oxide would affect about 90 commercial sterilization facilities owned and operated by approximately 50 companies. Three California companies applied for and received presidential exemptions for their EtO emissions in July.

They are located in Ontario and Vernon and operated by the company Sterigenics, which provides industrial sterilization technology for medical devices and other commercial products.

In January, a coalition of environmental and community groups challenged the EtO exemptions in federal court. The lawsuit from the Southern Environmental Law Center and the Natural Resources Defense Council argues that technology exists for facilities to comply with the tighter Biden-era standards without raising costs, and many facilities are already using it.

“EPA’s 2024 rule was an important and overdue step to reduce toxic ethylene oxide pollution and protect communities,” said Irena Como, senior attorney at the Southern Environmental Law Center, in a statement Friday. “Repealing this rule that is proven to significantly lower pollution exposure and cancer risks will subject even more people who work, live, and send their children to schools located near these facilities to harm that is entirely preventable.”

Sterilization and chemical industry groups support the plan.

“The EPA rule concerning ethylene oxide use in commercial sterilizers threatens to severely restrict access to vital medical products nationwide,” the American Chemistry Council said in a statement. “We commend the EPA for their commitment to reevaluating these policies.”

The EPA will hold a 45-day comment period about the proposal after it is published in the federal register. A final decision is expected sometime this year.

WASHINGTON — Six American airmen deployed to operations against Iran were killed after their refueling aircraft crashed in western Iraq, U.S. Central Command said Friday, bringing the U.S. death toll in the war to 13, as Defense Secretary Pete Hegseth announced the heaviest day of strikes yet.

The crash involved two aircraft in “friendly airspace,” the Pentagon said, adding that the other plane landed safely. The downed KC-135 refueling tanker is the fourth U.S. aircraft to crash during the war against Iran.

“American heroes, all of them,” Hegseth said at the Pentagon on Friday. “We will greet those heroes at Dover and their sacrifice will only recommit us to the resolve of this mission.”

Central Command said the incident is under investigation but was “not due to hostile or friendly fire.”

During the briefing, Hegseth described the Iranian leaders as “desperate” and “cowering” underground like rats. He said Iran’s Supreme Leader Ayatollah Mojtaba Khamenei “is wounded and likely disfigured,” but gave no intelligence to support the claim.

Khamenei has not been seen in public since he rose to leadership, but issued his first public statement Thursday vowing retaliation against U.S. and Israeli attacks, promising that Tehran will continue to choke off the world’s most crucial oil route — the Strait of Hormuz.

“Our revenge will be never ending, not only for the late supreme leader, but also for the blood of all of our martyrs,” he said.

The defense secretary said Friday would see Iran hammered with the heaviest round of air strikes yet seen in the two-week U.S.-Israeli operation that has razed buildings, complexes and factory lines all across Iran, killing at least 1,348 civilians, according to Iranian officials.

“No quarter, no mercy for our enemies,” Hegseth said.

And while Hegseth insisted that fighting will cease when the U.S. defeats Iran’s naval, missile, and nuclear weapons capabilities, President Trump’s public statements continue to sow doubt that the White House and Pentagon are aligned on the objectives of the mission.

Asked Friday by Fox News when the war might end, Trump said, “When I feel it — feel it in my bones.”

Iran’s blockade of the strait remains Tehran’s foremost leverage against its Western adversaries, and a serious political bane for Trump. The International Energy Agency warned Thursday that conflict has created “the largest supply disruption in the history of the global oil market,” which has sent oil prices surging 40% to $95 a barrel since Feb. 28.

Some 1,000 ships remain stranded in the Persian Gulf, many of them energy tankers that have been unable to carry oil and gas shipments from the Middle East to importers across the globe. Vessels that have attempted to traverse the embattled channel have been destroyed in Iranian attacks. Hegseth described Tehran’s strategy as “an act of desperation.”

The United Kingdom Maritime Trade Operations on Friday reported 20 incidents affecting vessels operating in and around the Arabian Gulf, Strait of Hormuz and Gulf of Oman in March.

Drone and missile attacks continue to assail gulf states, threatening to draw more players into the conflict. Thick black smoke was seen rising over Dubai’s skyline Friday after debris from an intercepted Iranian drone strike caused a fire and minor damage to a building within the Dubai International Financial Centre, according to the Dubai Media Office.

Europe has become increasingly involved, too. U.S. long-range bombers have begun flying offensive missions from British airbases, even as U.K. Prime Minister Keir Starmer explicitly permitted U.S. forces to use the bases “for defensive purposes only.” Starmer initially refused to cooperate in American hostilities in any capacity, but changed his approach after he drew criticism from Trump, who said, “He’s no Winston Churchill.”

The U.K., France, and Italy each deployed naval assets to the Eastern Mediterranean island of Cyprus, situated just 125 miles from Lebanon, after Iranian drone strikes hit U.K. bases. The island has emerged as a strategic — and exposed — nerve center in the U.S. offensive against Iran.

Meanwhile, Israel said Friday its strikes are “continuing and intensifying” in Lebanon and Iran. The Israel Defense Forces issued new evacuation orders in southern Lebanon on Thursday after overnight airstrikes in Beirut triggered retaliatory missile and drone attacks by the Iran-backed militant group Hezbollah.

Eight civilians were killed and nine others were wounded in attacks on the Lebanese city of Sidon on Friday, according to Lebanon’s Health Ministry. More than 100 children have been killed in the Israeli assault, the ministry said.

MEXICO CITY — Cuba has begun direct talks with the United States in an effort to solve “bilateral differences” between the two countries, Cuban President Miguel Díaz Canel said Friday.

The comments, broadcast nationwide in Cuba, are the first confirmation of bilateral talks between two governments that have been fierce adversaries for almost 70 years, since Fidel Castro’s revolution toppled the U.S.-backed dictator Fulgencio Batista.

What exactly the talks are about remains unclear, but the Trump administration—which has choked off oil supplies to the island, triggering a severe energy crisis—has been insisting that Cuba’s communist government must change.

In a statement released on social media, Díaz Canel said, “The primary purpose of this conversation is, firstly, to identify the bilateral problems that require a solution—based on their severity and impact—and, secondly, to find solutions for these identified problems.”

Rumors of direct talks between the two nations have been circulating for months, but neither Washington or Havana had confirmed the talks until now.

On Tuesday, the Cuban ambassador to the United States, Lianys Torres Rivera, told The Times that the Cuban government was “ready to engage with the U.S. on the issues that are important for the bilateral relations, and to talk about those in which we have differences.”

Trump and Secretary of State Marco Rubio, the son of Cuban immigrants, have been insistent that the current government must change.

“It may be a friendly takeover, it may not be a friendly takeover,” Trump told Latin American leaders gathered in Florida on Saturday.

“It wouldn’t matter because they’re down to, as they say, fumes. They have no energy. They have no money. They’re in deep trouble,” Trump said.

Trump responded to the Cuban leader’s willingness to negotiate on Friday morning by amplifying a news article with the headline:”Cuba confirms talks with Trump officials, raising hopes for US deal.” He posted that on his Truth Social account.

Rolling blackouts, shortages of food and medicine, a lack of gasoline and other shortfalls have become everyday occurrences on the island, home to 10 million. Images of uncollected garbage rotting on Havana’s streets have been broadcast across the globe. A lack of jet fuel has bludgeoned the critical tourism sector.

“The status quo is unsustainable,” Rubio said last month. “Cuba needs to change…And it doesn’t have to be change all at once. It doesn’t have to change from one day to the next.”

The Cuban announcement comes 13 days after the U.S. attacked Iran and two months after U.S. forces, deployed by Trump, deposed Venezuelan President Nicolás Maduro, a longtime Cuban ally, and brought him to New York to face drug trafficking charges.
