Calumet denies that its plant is responsible for any of the health issues in the area. Spokesman Noel Ryan would not answer any specific questions for this story but issued a statement that read, in part, “In recent years, there have been multiple and extensive air monitoring events by the U.S. EPA and the LDEQ [Louisiana Department of Environmental Quality] in and around the Shreveport refinery. None of these sampling events have shown unsafe air quality levels … Since acquiring the Shreveport refinery in 2001, Calumet has continued to make investments that enhance the safety and environmental compliance of the facility.”

White says Calumet has done a slightly better job at running the plant than its previous owners. But residents say the problems persist.

White’s friend and neighbor Joseph Ashley, 57, said every family in the neighborhood has a story about the plant. Ashley’s son Avery has sinus issues. His wife has bronchitis. His other son Caleb had to be rushed to the hospital after a particularly strong-smelling smoke was released from the plant four years ago. Since then, Ashley said, Caleb has had trouble breathing.

“He’s short of breath all the time,” Ashley said. “I wake up in the middle of the night because I want to make sure he’s breathing.”

Despite EPA and Calumet assurances that there’s little to worry about, White says her research proves otherwise.

A small neighborhood group White started, Residents for Air Neutralization, conducted a survey from August 2012 until April of 2013 of 647 residents who live on the blocks surrounding the plant. It found that 94 percent of respondents smelled a foul, chemical, sulfur or rotten egg smell coming from the plant on a weekly basis. Nearly 60 percent reported health issues they believed were related to the plant, including 15 percent who said they have experienced trouble breathing and other lung issues.

Four out of five residents told RAN they would relocate if they could afford it.

It’s not only health issues that make residents want to leave. They want to get out of a neighborhood where an oil refinery is its defining feature, providing its jobs, its smell and even its weather.

“When I’m out there monitoring, you can feel the particles falling on your face,” White said.

Ashley calls it black snow.

Calumet has been fined twice for its emissions. In 2010, the LDEQ fined the plant $1 million and required Calumet to make $11 million to $15 million in emission control improvements. Calumet has until 2015 to comply.

In 2011 the EPA performed a surprise inspection at the plant and found several violations, including accidents and spills that were underreported and a critical lack of early warning air monitoring systems. The agency fined Calumet $326,000.

But residents and many experts say these improvements likely won’t be enough because regardless of what Calumet does, running an oil refinery so close to people’s homes is always likely to cause problems.

“Just given the fact of what running a refinery involves, basically, boiling oil, there will always be emissions,” said Mark Latham an environmental law professor at Vermont Law School.

And Latham said it would be nearly impossible for Shreveport residents to take legal action against the plant because, aside from its few run-ins with environmental agencies, Calumet is staying within its legal limits.

When it comes to accidents and emissions, Calumet’s Shreveport plant is actually on the very low end of Louisiana’s refineries. The Bucket Brigade, a nonprofit group that helps people like Velma White conduct air quality tests, calculated that Calumet released 331,270 pounds of emissions into the air from 2005 to 2013. That’s about 5 percent of the emissions from the state’s biggest emitter, Chalmette Refining, which released over 7 million pounds.

That’s why residents aren’t holding their breath for the EPA or LDEQ. They suspect that even after improvements are made to the plant’s monitoring, their health issues will still persist and that the smell will be ever present.

White says that without government action, it’s up to people like her to persuade the plant to give the community what it wants and buy it out.

But she says at this point, she isn’t expecting that to happen either.

“The oil and gas industries … they do what they want to do, and people are supposed to accept it,” she said. “I keep up the work because I feel compelled to do it, not because I think they’re going to do something about it.”
