The Department of Justice is searching for to compel a chemical manufacturing plant to curb its emissions in a area the place the estimated most cancers threat is among the many highest in the USA.
The motion raises the stakes in a longstanding battle between the Louisiana plant, close by residents and the Environmental Safety Company.
The Denka Efficiency Elastomer plant in LaPlace, Louisiana, alongside the Mississippi River, is the one facility within the U.S. that produces chloroprene, a chemical used within the manufacturing of neoprene. Neoprene is an artificial rubber present in merchandise akin to wetsuits and adhesives.
The EPA recognized chloroprene as a possible human carcinogen in 2010.
Denka mentioned in an announcement that it has lowered emissions by about 85% because it took over the plant in 2015. However the estimated pollution-related most cancers threat within the space continues to be one of many highest within the nation, in accordance to the EPA.
Now, the DOJ has filed a criticism to compel Denka to additional scale back its hazardous emissions. The criticism, first reported by NBC Information, was filed Tuesday in U.S. District Courtroom for Japanese Louisiana on behalf of the EPA below the Clear Air Act.
In its assertion, Denka mentioned it strongly disagrees with the federal authorities’s resolution to file a authorized criticism and with the EPA’s evaluation of the well being dangers the plant’s emissions pose to the encircling group.
“EPA’s allegation instantly contradicts the company’s personal prior statements, credible knowledge on well being in St. John the Baptist Parish and the very best out there science on the chemical chloroprene,” the assertion mentioned.
The corporate added that it “stays dedicated to figuring out and implementing extra emission reductions the place doable.”
Denka’s facility is alongside a stretch of the Mississippi River that activists and residents have nicknamed “Most cancers Alley” due to the unusually excessive most cancers threat amongst communities there and the emissions that come from the quite a few vegetation within the space.

Through the years, Denka has dedicated to taking steps to scale back the plant’s emissions. In complete, these modifications have price greater than $35 million, the corporate mentioned in its assertion.
However on-site inspections by the EPA in April and Could 2022 discovered that Denka was not assembly regulatory necessities for the storage and disposal of chloroprene waste, which contributes to emissions of chloroprene from the plant.
Even when Denka’s facility was shut down for a month in September 2021 after Hurricane Ida, a small monitoring demonstration check by the Louisiana State College Faculty of Public Well being revealed detectable ranges of chloroprene in two out of 10 air samples, in accordance to the researchers.
That 2021 check, which was not a proper research, discovered ranges roughly 4 instances above the EPA’s beneficial most annual common chloroprene focus. The air samples had been taken at or throughout the road from a close-by elementary college.
LaPlace is within the majority-Black St. John the Baptist Parish, about 30 miles outdoors of New Orleans. The plant is one in every of many who activists argue places undue well being dangers on Black communities within the space.
The EPA’s Workplace of Environmental Justice and Exterior Civil Rights partly blames state companies; In an October letter, it wrote that the Louisiana Department of Environmental High quality and the Louisiana Department of Well being’s failure to pursue stronger motion in opposition to Denka disproportionately uncovered Black residents to dangerous air pollution.
The EPA mentioned it discovered throughout an investigation that state companies had failed to present residents with details about the most cancers dangers related to chloroprene ranges within the space, amongst different issues.
In an announcement Tuesday, EPA Administrator Michael Regan mentioned the Justice Department’s transfer adopted his pledge to take sturdy motion for communities dwelling close to the plant.
“The corporate has not moved far sufficient or quick sufficient to scale back emissions or guarantee the security of the encircling group,” mentioned Regan, who has been vocal about his dedication to environmental justice. “This motion isn’t step one we now have taken to scale back dangers to the folks dwelling in Saint John the Baptist Parish, and it’ll not be the final.”
