Louisiana plant at the center of an environmental justice fight halts
operations

NEW ORLEANS (AP) — A petrochemical plant in Louisiana accused of
increasing cancer risks for a majority Black community indefinitely
suspended operations largely due to the high cost of reducing toxic
pollution.
Japanese firm Denka announced Tuesday that its synthetic rubber facility
hemorrhaged more than $109 million in the past year. The company cited
weakening demand, staffing challenges and rising costs as reasons why
“improving profitability in the near term would be difficult.”
Denka also attributed much of its financial woes to what it has
described as “unfair and targeted” pollution control measures.
Last year, the Environmental Protection Agency sought to rein in
dangerous chemical emissions from hundreds of facilities including
Denka's. The Biden administration's environmental justice campaign
spotlighted Denka's plant, located about 30 miles (48 kilometers)
northwest of New Orleans in St. John the Baptist Parish.
Under the Trump administration, the EPA withdrew a federal lawsuit
against Denka alleging it exposed a predominantly Black population to
unacceptable cancer risk — the highest nationwide — from the facility's
emissions of chloroprene. Last year, officials shut down a nearby
elementary school due to concerns about emissions exposure.
“I am elated that we are waking up every day now with no chloroprene in
our air,” said Tish Taylor, a local environmental activist. She added
that she was under no illusion that the company was concerned about its
impact on her community's health: “The petrochemical industry around us
doesn’t care about human beings. They care about their bottom line.”

The cost to reduce pollution
Denka produces Neoprene, a synthetic rubber used in wetsuits, laptop
sleeves and other common products.
In suspending operations, Denka cited the “significant cost” of
“pollution control equipment to reduce chloroprene emissions,” which the
company said it “did not anticipate” when it purchased the facility from
DuPont in 2015. The company also cited “a shortage of qualified staff
necessary to operate new pollution control equipment and implement other
emission reduction measures.”
In court filings last year, Denka said it had spent more than $35
million on equipment to reduce emissions by 85% since 2017. But harmful
emissions consistently remained higher than federal guidelines.
Denka said it remains “deeply grateful” to Republican Gov. Jeff Landry,
who supported the company last year as it fought an EPA rule mandating
the facility swiftly reduce chloroprene emissions. While the Trump
administration has pledged to rewrite this policy, the company noted the
outcome remains uncertain.

 Denka said it is working with
Landry's administration to consider “all options,” including “a
potential sale of the business or its assets.” But no decision had
been made regarding a “permanent closure” of the facility or
“workforce reductions.”
Landry did not respond to a request for comment.
A market ‘slowdown’
Denka said it “faces a sustained slowdown in the global market
demand for Neoprene, along with increases in energy prices, raw
materials, and repair work that have been exacerbated by inflation.”
The company's statement noted “rising energy costs,” “weakening
global economic environment for chloroprene” and “supply chain
disruptions" as other factors.
The Denka facility needed large amounts of chlorine to produce
chloroprene, said George Eisenhauer, an analyst with commodities
consulting company Argus Media. It costs more than twice as much to
purchase and import chlorine into the U.S. as it does in other
leading chloroprene production sites like Europe, Japan and China,
he said.
The costs rose over the past few years after a major U.S. chlorine
producer shut down, Eisenhauer added.
Trump's tariff policies have not significantly affected the price
because chlorine is typically imported into the U.S. through Mexico
or Canada.
Local activists remain wary
Denka's facility is in the 85-mile (137-kilometer) stretch of the
Mississippi River between New Orleans and Baton Rouge officially
called the Mississippi River Chemical Corridor and commonly referred
to by environmental groups as “Cancer Alley.”
Robert Taylor, 84, and other environmental activists warily
celebrated Denka's announcement. Taylor, who lives near the
facility, pushed for stronger environmental regulations, only to
watch the Trump administration roll them back.
“They have given these guys all the protection they need from
advocacy groups like mine,” he said, referring to the Trump
administration. “So that’s why I am a bit puzzled by the action they
(Denka) are taking now.”
He wondered whether the company would eventually resume operations
or sell the plant to a company that could restart production.
“I think the community needs to be on guard and be prepared to
continue our advocacy for our clean air and safe environment.”
