The facility's operator announced Tuesday that it had suspended all production indefinitely at a controversial chemical plant in the center of Louisiana's Cancer Lane.

St John Parish’s Denka Performance Elastic Plants have long been linked to chronic air pollution issues and are the subject of a year’s Guardian Report series that examines the disproportionate rates of cancer risk experienced by most Black Fence Line communities around the facility.

Denka, a Japanese chemicals company, cited growing regulations during Joe Biden's presidency and “remaining slowing global market demand for his products,” a synthetic rubber called Neoderene, which was produced on site. The company has not decided to close permanently, a statement said, adding that the chemical giant "explored all available options for the website's future, including selling the facility."

The fight for clean air in fence line communities has become a call for national and international environmental justice Clarion, prompting the Biden administration to take many interventions. These include the introduction of new rules regarding the plant's main pollutant, possible human carcinogens, called Cluplon, and a U.S. Department of Justice lawsuit aimed at forcing Denka to reduce its pollution.

The Trump administration is trying to revoke many of these initiatives. Donald Trump's Justice Department dropped the lawsuit in March, citing "ideological overreach" and new executive orders against the so-called "DEI program."

Denka said the government is also "committed to rewrite" the Chloron Rules of the Biden-ERA era.

The company said in a statement that it hit 16.1 billion yen (about $109 million) in its "huge loss of financial performance" last year. Although the company cites a decline in global demand, the company also blames uncertainty caused by Joe Biden's financial collapse in the U.S. facility.

The Guardian reveals how the former owner of the plant, the U.S. chemical giant Dupont, sold the facility in 2015 in a secret deal, citing concerns about potential environmental regulations and their impact on profit margins. Dupont allegedly rejected information about these issues before it was sold to Denka.

DuPont did not immediately respond to a request for comment on Tuesday.

Denka once again mentioned the 2015 sales on Tuesday, indicating that it "had not anticipated" the need to install pollution control technology and equipment at the time of purchase. Since purchasing the facility, the Japanese company has invested more than $35 million in emission offset technology and claims it has reduced Clover emissions by more than 80%.

It is worth noting that the EPA recorded Chloren readings continue to show a measure far exceeding the federal government's lifetime exposure guidance.

Residents who have fought pollution in the factory for years expressed some cautious optimism on Tuesday.

"It (suspends production) has nothing to do with us, the community. They don't care about us," said Mary Hampton of Infinite Community Action. "What I'm seeing now is that they never intended to lower emissions. But now they're being hit internationally and they have no choice."

Hampton, who lived in the reserve community on the Fence Line all his life and lost many family members due to cancer, added that the community remains concerned about potential sales to another manufacturer.

“I’m worried that it’s just a temporary thing,” Hampton said. “I’m worried that they’ll sell to other people, they’ll adopt the same regulations and keep doing what they want.”
