Thousands Evacuated After Toxic Leak and Massive Fire at Louisiana Oil Refinery

The blaze is the latest fossil fuel-related disaster to threaten residents of Louisiana’s so-called “Cancer Alley.”

Chemical plants and factories line the roads and suburbs of the Louisiana region known as Cancer Alley, on October 15, 2013.

A mandatory evacuation was ordered for thousands of people living within a two-mile radius of a Marathon Petroleum refinery in Louisiana’s so-called “Cancer Alley” after a chemical leak and massive fire broke out at a storage tank there on Friday.

The temporary evacuation order, which Marathon Petroleum called “precautionary,” followed a leak of naphtha — a hazardous and highly flammable liquid hydrocarbon mixture — and blaze at the refinery in Garyville in St. John the Baptist Parish, located about 45 miles upriver from New Orleans.

About 8,660 people live within two miles of the refinery, according to One of them, 42-year-old Lashonda Melancon, said she was trying to figure out where to go with her 14-year-old daughter.

“I’ve got asthma bad and this is not good for me,” she said.

People living near the refinery said flames could be seen dozens of feet in the air. The smoke plume from the disaster was visible from outer space.

Marathon Petroleum said in a statement: “The release and fire are contained within the refinery’s property and there have been no injuries. As a precaution, air monitoring has been deployed in the community. No off-site impacts have been detected. All regulatory notifications have been made.”

However, contained does not mean controlled — the latter means extinguished — and Marathon Petroleum spokesperson Justin Lawrence said the company did not know when the blaze would be put out.

Operational since 1977, the 200,000-barrel-per-day facility is the newest oil refinery in the United States. Marathon Petroleum’s three biggest shareholders are the Vanguard Group, SSgA Funds Management, and Blackrock, private equity firms that have come under fire for financing fossil fuel expansion during a worsening climate emergency.

In May, Reuters reported there had been 13 U.S. refinery fires in 2023, the majority of them along the Gulf Coast.

St. John the Baptist Parish is located in what’s known as Cancer Alley or Death Alley, a swath of predominantly Black parishes — the Louisiana equivalent of counties — between New Orleans and Baton Rouge containing nearly 150 oil refineries and plastics and chemical plants, many of them located along or near the Mississippi River.

In neighboring St. James Parish, the U.S. Environmental Protection Agency has reported an 800 percent cancer hazard increase due to petrochemical facilities in the parish between 2007 and 2018.

The area is also known as a “sacrifice zone,” or place where polluting industrial facilities are built in close proximity to residents — usually people of color or those with low income.

Responding to the disaster, Antonia Juhasz, senior fossil fuel researcher at Human Rights Watch, wrote on the social platform formerly known as Twitter that “such events are an all-too-common and exceptionally dangerous reality for those living within fossil fuel and petrochemical ‘sacrifice zones.'”

Anne Rolfes, executive director of the Louisiana Bucket Brigade, a frontline community advocacy group, said in a statement that “the petrochemical industry is here in Louisiana for one reason only: To make as much money as possible.”

“As long as the state of Louisiana continues to look away from fires and mushroom clouds, these accidents will continue,” she continued. “I have been dealing with this for nearly a quarter of a century. There are terrible accidents, workers are burned alive, and the state of Louisiana does nothing.”

“Workers and residents are left to bear the brunt of the industry’s negligence and predatory expansion that continue to jeopardize our health and safety,” Rolfes added.

Briefly, we wanted to update you on where Truthout stands this month.

To be brutally honest, Truthout is behind on our fundraising goals for the year. There are a lot of reasons why. We’re dealing with broad trends in our industry, trends that have led publications like Vice, BuzzFeed, and National Geographic to make painful cuts. Everyone is feeling the squeeze of inflation. And despite its lasting importance, news readership is declining.

To ensure we stay out of the red by the end of the year, we have a long way to go. Our future is threatened.

We’ve stayed online over two decades thanks to the support of our readers. Because you believe in the power of our work, share our transformative stories, and give to keep us going strong, we know we can make it through this tough moment.

At this moment, we have 24 hours left in our important fundraising campaign, and we still must raise $19,000. Please consider making a donation today.
