Red Alert: A refinery spilled toxic waste into the community and knew about it for months
The Atlantic Alumina, a.k.a. Atalco, bauxite refinery in Gramercy, Louisiana. (Wes Muller/Louisiana Illuminator) This article is the first in a series on the environmental costs of America's last remaining alumina refinery. GRAMERCY — For several months, a River Parishes refinery unlawfully discharged industrial toxic waste containing arsenic, cadmium, chromium and other toxic heavy metals into public areas and waterways, state records show. The company, Atlantic Alumina, also known as Atalco, has so far racked up 23 violation notices from the Louisiana Department of Environmental Quality after inspectors first discovered the pollution in August. It involves a slurry of industrial 'red mud' byproduct that has eroded through the giant levees surrounding the facility's waste containment lakes and spilled onto public property. The toxic sludge has killed vegetation and contaminated the land along its path to a local drainage system that flows to the Blind River Swamp of Lake Maurepas, according to a 606-page LDEQ inspection report finalized in March. The incident marks the first known case of red mud levee breaches at an American bauxite refinery. When asked for details, LDEQ spokesman Gregory Langley had little information to share about the prolonged discharge other than to say it is currently under investigation with the agency's enforcement division. The only enforcement action taken as of May 29 is a warning letter LDEQ sent to Atalco. A review of thousands of pages of state and federal documents and interviews with scientists and area residents indicate that Atalco polluted public land and state waterways with the most toxic non-radioactive elements on the planet and allowed that pollution to continue for months — never notifying the outside community. Atalco's refinery occupies roughly 3 square miles of land where St. James and St. John the Baptist parishes meet on the Mississippi River's east bank. The site specializes in refining bauxite, a rust-colored powder of raw metals and minerals, into aluminum oxide or 'alumina' in the form of an ultra-fine white powder. Atalco sells the alumina to metal smelters that need it to make finished aluminum. Opened in 1958 as Kaiser Aluminum, the Gramercy facility is the only remaining bauxite refinery in the United States and therefore the nation's only domestic source of a critical metal feedstock. Atalco produced 669,261 metric tons of aluminum oxide last year, state records show. For every ton of aluminum produced from Atalco's work, bauxite refining generates an estimated 2.5 tons of waste byproduct, according to the U.S. Environmental Protection Agency. One of the main problems in refining bauxite is there are not many good options for what to do with all that waste, most of which takes the form of a thick red mud. The waste comes from a part of the process in which bauxite is heated in a pressurized vessel with sodium hydroxide, a highly caustic chemical. The alumina compounds are then filtered out and separated, while the toxic byproduct is stored in the facility's six red mud lakes. The lakes are open-air ponds, each roughly 150-200 acres in size surrounded by large earthen levees, some as high as 50 feet, meant to contain the thick liquid waste. Four of the lakes, including a 'surge' or overflow basin, were constructed in the early 1970s without any liners that would help prevent the heavy metals and chemicals from seeping into the soil below. 'It is very dangerous,' said Slawomir Lomnicki, an environmental scientist at LSU. 'There can be a lot of toxic metals leaching out of it and getting into the groundwater.' Groundwater contamination from leaching is a constant risk that exists when Atalco's systems are operating normally. The public drinking water system in St. James Parish regularly monitors for that kind of contamination, according to Parish President Peter Dufresne. Officials with the St. John Parish water system did not answer multiple phone calls last week. A greater risk to the community from bauxite refineries in general is the rare case of a levee breach at a red mud lake, which can cause toxic waste to directly contaminate public waters and soils, scientists said. Until this reporting, the last known breach at a bauxite refinery occurred in Hungary in 2010. The failure of a red mud reservoir sent 35 million cubic feet of waste into nearby villages, killing 10 people and injuring 150 others. In the wake of that incident, industry officials told the American public that a levee breach at Louisiana's bauxite refinery would be unlikely because the levees are 'periodically checked by state and federal regulators,' according to a news report from that time. That unlikely event has happened at Atalco. With a caustic level higher than drain cleaner and elevated concentrations of heavy metals, Atalco's waste slurry eroded through levees in multiple locations at multiple lakes, forming canyons as deep as 10 feet that allowed the toxic waste to escape, records show. A water sample LDEQ had tested from a public ditch outside the plant detected arsenic at a concentration nearly 1,400% higher than the level considered safe by state groundwater and EPA drinking water limits. The sample also contained cadmium at levels above those same limits. A soil sample taken from the same ditch contained mercury, beryllium, cadmium and chromium — all at concentrations above the average background levels found in U.S. soils. The cadmium was nearly 400% higher, and the chromium was 900% higher than LDEQ's standard limits for soil. Chromium is the most toxic non-radioactive element on earth and is about three times more poisonous than arsenic, according to EPA toxicity factors. Historic water quality data for the Blind River, recorded from 1979-99, show heavy metal concentrations nowhere near those levels. 'With this kind of facility, the worst major accident that can happen is a breach of the lake [levees],' said Corinne Gibb, a chemist who works with the environmental watchdog Louisiana Bucket Brigade. The group has monitored incidents at the alumina refinery for years. It is unknown when the mud lake levees first began to erode, but state and federal records show the pollution lasted for months and continued even after Atalco became aware of the problem. The company has not responded to the Illuminator's multiple requests for an interview. Federal inspectors with the Mine Safety and Health Administration (MSHA) documented several hazards at Atalco's levees last summer and voiced concerns about the risks they posed to the workers at the plant. 'There were several mud lakes at the facility that was (sic) not being maintained,' MSHA inspector Brandon Olivier wrote in a citation dated June 25, 2024. Trees and shrubs obscured sections of the levees, making thorough inspections impossible, Olivier added. A few weeks later, on Aug. 14, the MSHA issued Atalco another citation after inspectors discovered caustic waste 'seeping through various locations on the east and west side of Mud Lake #4' and flowing downhill 'into the roadway and ditches.' LDEQ later noted the Aug. 14 citation was the first formal written notice Atalco received about the levees having a breach with dangerous toxic waste escaping from its facility. Other dangers present at the Atalco plant had already drawn regulators' attention at that time. Just days prior, on Aug. 4, the public was reminded just how dangerous the chemicals at Atalco could be when 45-year-old Curtis Diggs, a contract worker from Waste-Pro USA, fell into a pit of sodium hydroxide at the plant because a grate that covered the pit was missing and the entire floor was flooded with several inches of the caustic cloudy liquid. The chemical, the same that is stored in the red mud lakes, left Diggs with severe burns from which he did not recover, according to LDEQ records. He died in a New Orleans hospital on Sept 2. MSHA investigated the fatality and learned that Atalco personnel had removed the grate on July 30, 2024, to try to pump out the flooded area and failed to put anything in its place or even a warning marker, creating a dangerous pitfall left open for five days and virtually invisible. MSHA charged Atalco with three regulatory violations and charged Waste-Pro USA with two, faulting both companies for 'aggravated conduct' that involved an extraordinary pattern of negligence, though it's unclear if any fines or penalties have been issued as of May 30, according to federal records. Atalco uses sodium hydroxide to refine bauxite into alumina. After the refinement process, it stores the used sodium hydroxide in the lakes with the other waste. Despite the heightened scrutiny from state and federal regulators at the time, by mid-September Atalco still had not repaired the levee breaches to Red Mud Lake 4 that federal inspectors cited the month before. Nor did the company thoroughly inspect its other lakes to look for similar breaches because, as the records indicate, similar breaches were there — if only the company had looked. On Sept. 17, MSHA inspectors found a breach in the levee around another lake, Red Mud Lake 1 East, with a stream of hazardous waste flowing freely across the roadway. 'The caustic was observed seeping through the side of the levee for approximately 50 yards across the roadway and to the ditch,' the citation states. 'The mud lake is access[ed] by the plant operators daily and contractors for service, and this condition exposes them to injuries if there is a dam failure due to the seepage.' Based on further inspections that same day, MSHA cited Atalco for a third levee break — at Red Mud Lake 2. On that single day, three of Atalco's six waste lakes had confirmed breaches with streams of poisonous chemicals flowing freely to areas they weren't permitted to go, including the Blind River Swamp — a popular recreational fishing spot in the Lake Maurepas backwaters. LDEQ officials first arrived at the plant Sept. 20 to initiate a routine compliance inspection. Agency records show state officials met with Atalco managers, conducted an interview and toured parts of the facility. However, they were unable to inspect some of the lakes and levees because the plant manager told them the access roads were too wet to travel on. LDEQ first documented the levee breaches five days later when they were contacted by the federal inspectors, according to state records. Atalco had still not officially notified LDEQ of the levee breaches — something the company should have done immediately upon learning of them in accordance with Atalco's permit requirements as well as state and federal laws. Local officials have also been kept in the dark. When asked about the events during an impromptu meeting with a reporter Thursday at the State Capitol, St. James Parish President Peter Dufresne said he was unaware of Atalco's levee breaks that contaminated neighboring land and drainage with toxic waste. Dufresne declined an interview but asked the Illuminator for copies of LDEQ's inspection reports. In October, the records show, state inspectors discovered erosion channels in the levee of a fourth lake, Red Mud Lake 3. They also saw for themselves the levee breaches that federal inspectors documented two months before. The erosion channels were still there, and the caustic waste was still escaping from those lakes. So much waste had escaped that it also overwhelmed the facility's secondary containment system, which is a network of interior ditches just outside of the levees used to catch any chemical spills or leaks from the lakes. The backup ditch at one location had overflowed, sending the toxic slurry across the highway just north of the Veterans Memorial Bridge. Atalco was also, as a matter of protocol, unlawfully using a stormwater ditch as a backup containment ditch. Three company officials, apparently unaware that they weren't permitted to use the ditch for toxic waste disposal, told LDEQ inspectors that they routinely used it for containment, according to the inspection files. In other areas, LDEQ inspectors saw that the waste slurry had accumulated to 'nearly the height of the levee' in some of the lakes, the agency's files note. The waste level in the lakes should never be allowed to rise higher than two feet from the top of the levee. Ultimately, in site visits over the next three months, LDEQ inspectors viewed and documented levee breaches at four of Atalco's six lakes, prompting the state agency to cite Atalco multiple times for failing to inspect and failing to repair the levees. Erosion of the levees was a very real possibility that Atalco had long known about. In its 2010 permit renewal applications with the state, the company had addressed the topic at length, promising to prevent erosion by conducting daily inspections of the levees and keeping written logs of those inspections. The state included those as specific ongoing requirements in the final permit issued to Atalco. At that time, the company was in the process of raising its levees from 30 feet to 50 feet high, according to the permit application. By the time state and federal officials began prodding the company last August, Atalco had not consistently inspected its lakes and levees in over three years and was missing hundreds of daily inspection records from July 30, 2021, to Dec. 18, 2024, according to LDEQ's summary of violations. On Oct. 23, state officials noted the company was constructing a new berm to contain the breach at Red Mud Lake 4, which Atalco had known about since at least Aug. 14. The breach at Red Mud Lake 3 continued until Dec. 4, according to the LDEQ file. On that day, Atalco managers accompanied state inspectors into the field when they noticed multiple streams emerging near an access road and traced it back to 'one erosion channel with an estimated depth of at least 10 feet.' You would definitely get injuries and skin burns from it. The plants and any fish in the area would die from that. You can't survive that high of a pH. – Corinne Gibb, chemist, Louisiana Bucket Brigade During their site visits in October, the state inspectors took pH readings from various pools of standing waste that had escaped from the lakes The pH scale ranges from 0 to 14, with water having a neutral pH of around 7. Lower values indicate acidity, while higher values indicate alkalinity. Substances at the extreme ends of the scale in either direction can eat through solid materials such as steel and concrete and are very dangerous to most life forms. The LDEQ detected high pH at every location, with one puddle logged at a high of 12.49 — the same alkalinity as most caustic drain clog removers and ammonia-based cleaners. The inspectors also photographed dead or dying vegetation, petrochemical sheens, and white and yellow chemical residues in many of the locations where the slurry had traveled. 'Just the pH by itself is concerning … That is very high,' Gibb, the chemist, said. 'You would definitely get injuries and skin burns from it. The plants and any fish in the area would die from that. You can't survive that high of a pH.' State inspectors had testing done on water and soil samples from off-site locations in the public drainage system and on-site locations near the erosion streams. Simultaneously, Atalco personnel collected their own batch of samples and sent them to a separate lab for independent testing. LDEQ's soil samples contained significantly elevated levels of cadmium, chromium and nickel — all toxic carcinogens. Atalco's samples reaffirmed the LDEQ's lab results and detected even higher levels at one location. The company's sample taken from public property outside the facility contained cadmium at roughly 1,000% higher than what the state considers safe for people. Additionally, the levels of chromium and nickel measured 1,700% and 300% above their respective state standards, the lab reports show. Gibb and Lomnicki, the LSU scientist, said these three heavy metals, along with arsenic, are among the most dangerous non-radioactive substances on the planet. Exposure to excessive levels can cause a range of serious health issues, including cancer and blood poisoning. Ganga Hettiarachchi, a Kansas State University professor of soil and environmental chemistry, said cadmium could pose the greatest long-term risk because it spreads easily and accumulates in living organisms over time. Enough small doses during a given time period can add up to a fatal dose, she said. Cadmium is highly toxic to humans in short- and long-term exposure settings. Small concentrations ingested or inhaled can cause gastrointestinal or respiratory illness, while higher concentrations can cause cancer, cell death, neurological damage and organ system failure, according to the National Institutes of Health. Increasing the risk from cadmium is that it can be easily spread across far distances and transfer from soil into crops, Hettiarachchi said, posing risks to humans and animals if they eat those crops. 'It could easily end up in our food,' she said. 'That has been historically the main pathway for cadmium.' If cadmium gets into surface water or groundwater, it can become an even bigger problem, especially if that water is used for irrigation, she added. 'The area of damage can expand further and further over time,' Hettiarachchi said. Cadmium was present at elevated levels in two of Atalco's water samples and four of LDEQ's. The highest concentration was 400% above the level considered safe in a water sample taken from an erosion channel within the perimeter of the facility. It also had high levels of chromium and lead. All seven water samples that LDEQ had tested contained elevated levels of arsenic. One of them taken from outside the levee of a red mud lake detected arsenic at a level 9,000% higher than state and federal safe limits, and it contained high levels of cadmium, nickel and thallium. Six out of the seven samples Atalco personnel collected contained arsenic at levels beyond what is considered safe. LDEQ has yet to address the risks Atalco's red mud runoff could pose to the community. Langley, the agency's spokesman, said it has yet to determine what the public impact might be. 'Obviously those are things we don't want going into state waterways,' Langley said. Part Two: For some nearby residents, the levee breaches at Atalco are just the latest incident in a familiar pattern. The second story in this series reveals why the incident at Atalco was foreseeable based on the history of the plant and the many accidents and environmental exposures to the nearby communities. 'They're turning a blind eye to it,' said Gail LeBouef, who's lived near the plant since 1999. SUPPORT: YOU MAKE OUR WORK POSSIBLE

At America's last alumina refinery, a trade war spells trade-offs
Trump tariffs Trump wants the U.S. to make more aluminum. In Louisiana, home to the only domestic producer of a material essential to that process, some say a ramp-up would take years and worsen pollution. By Alexandra Byrne and Travers Mackel President Donald Trump wants to reinvigorate American industry with tariffs on metals, cars and dozens of foreign exporters. In Gramercy, Louisiana, home to the nation's last refiner of the key material for making aluminum, locals aren't sold on joining any such revival. 'It would be a good thing to go out of business,' Barbara Dumas, 58, said of the plant she's lived across the river from for 15 years. Like many residents, she bemoans the area's industrial pollution and believes her community would be better off without the refinery. 'It may hurt the people that's working there, but at least people around here can live safer.' Atlantic Alumina, also called Atalco, became the last U.S. refinery of its kind after another one 20 miles away closed in 2020. On the banks of the Mississippi River halfway between New Orleans and Baton Rouge, Atalco's 550 workers crush, wash and heat Jamaican-mined bauxite in a series of solutions. What starts as a rust-colored rock comes out as powdery white aluminum oxide, a compound known as alumina that resembles sugar but whose granules are hard enough to scratch glass. The product is sold to smelters to make 'primary' aluminum, the raw material that manufacturers turn into everything from beer cans to plumbing parts. The Atalco plant says it single-handedly supplies about 40% of the alumina used in the United States. If our company closed, we would be the only point of failure for that entire industry. Mark Hansen, CEO of Atlantic Aluminum's parent company 'It's been a very difficult operation,' said Mark Hansen, the CEO of Concord Resources, which became Atlantic Aluminum's majority owner in 2021. The complex, first commissioned in 1957, has been pummeled recently by hurricanes and inflation, but Hansen said it's important to keep the site running for national security. 'If our company closed, we would be the only point of failure for that entire industry in the United States,' he said, noting that the sector has seen 'a dramatic decline' in the last two decades. Trump's 25% tariffs on foreign-made aluminum, which took effect for most countries March 12 alongside comparable duties on steel, aim to reverse that. The sweeping levies he unveiled Wednesday on virtually all imports could prove a mixed bag, spurring demand for domestic wares while raising many producers' costs. Still, tariffs could buoy at least some parts of the domestic aluminum industry, analysts say: By making international supplies pricier, the American-made metal should become more competitive for buyers, at least in the short term. But the new metal tariffs don't cover alumina, and Hansen said his modest efforts to lobby Washington policymakers haven't had much success. 'It's not like we're Coca-Cola or something,' he said. 'We don't get that level of attention.' A White House spokesperson said the administration expects the aluminum tariffs to increase the nation's production capacity for the critical metal, adding that its efforts to reduce energy costs and slash regulations would also boost the primary aluminum industry. After decades of offshoring some of the most energy-intensive parts of the alumina refining process, the United States makes far less of the material than it uses. Smelters, just four of which remain domestically, rely on imports for about 60% of their alumina needs. Jobs in the primary aluminum sector have plummeted nearly 70% since 2013, the Aluminum Association estimates. Most job growth has been in secondary aluminum, among 'downstream' companies like product fabricators and recyclers. The domestic industry can't continue to expand without foreign-made primary aluminum, said Charles Johnson, the trade group's CEO. 'We are very encouraged by some of the actions that President Trump has taken as he has entered office,' he said, including the call to ramp up smelting in the U.S., but Johnson said that process could take a decade. Until then, the downstream sector needs access to foreign supplies — especially from Canada, which the Aluminum Association and other industry stakeholders have urged the administration to spare from tariffs even as they cheer duties on China, a top exporter of cheap metals. You don't see butterflies. You don't see nothing around here. Willie Youngblood Sr., Vacherie, La. 'It's not an easy thing' to reboot domestic metal production, said Morris Cohen, a supply chain expert at the University of Pennsylvania's Wharton School. 'It takes time and a lot of effort' and involves 'a lot of trade-offs,' he said. Pollution is one of them, according to those who live near the Atalco plant. 'I wouldn't be breathing too much if I were you,' said Willie Youngblood Sr., 'not around here.' The 67-year-old said he's watched bauxite shipments roll up to the Gramercy complex for 40 years from his home across the river in Vacherie. Residents of St. James Parish, which includes both communities, say airborne particles from the alumina refinery are contributing to a number of illnesses. Youngblood, who uses an oxygen tank, partly attributes his lung troubles to the plant's emissions. He said he doesn't hang clothes out to dry because the bauxite dust turns everything red. 'Your car gets covered with it,' he said. 'You don't see butterflies. You don't see nothing around here.' The stretch of the Mississippi River between New Orleans and Baton Rouge is widely known as 'Cancer Alley,' an industrial corridor once home to slave plantations and now the site of large petrochemical facilities that regulators and activists have long blamed for the area's well-documented health problems. Bauxite refinement generates hazardous waste with high levels of arsenic and chromium along with naturally occurring radioactive materials, according to the Environmental Protection Agency. The Atalco plant was investigated in 2020 by Louisiana regulators for alleged air-quality violations, a matter it settled in 2022 for $75,000 without admitting fault. If the trade war juices demand for Louisiana alumina and Atalco ramp ups its output in response, locals would suffer, said Anne Rolfes, director of the Louisiana Bucket Brigade, an environmental advocacy group. 'Increased production means a lot more fine particulate pollution for the people' in the area, she said. St. James Parish, where 47% of the residents are Black, was among a few parts of rural Louisiana where voters didn't back Trump by large margins. He won it by a single percentage point in November while netting 60% support statewide. 'We need some kind of economic development that's healthy, not just relying on these big polluters,' Rolfes said. Hansen said management has addressed concerns about dust from the refinery, which he said is always trying to be a good neighbor. 'There's no overriding concerns that make it an unworthy operation in the American industrial economy,' he said. 'It's been there for longer than I've been alive.' John Fleming, Louisiana's Republican treasurer, said Trump's tariff agenda could help businesses like Atlantic Aluminum 'because that's less competition from overseas.' He said the state lost major industrial employers after the North American Free Trade Agreement took effect in 1994. Look, the United States can outcompete anybody. John Fleming, Louisiana State Treasurer 'Free trade did not work out well for us because it wasn't free or fair trade,' he said. 'In this case, we're returning to a fair trade.' 'Look,' Fleming added, 'the United States can outcompete anybody.' For now, Hansen is just trying to keep production levels steady and has no plans to expand. If tariffs wind up bolstering U.S. smelting capacity, he said it could boost Atalco's customer base — though that would likely take years. 'We think there's a future for that, but it does sometimes involve shorter-term higher costs to make sure that the resiliency of those industries is there,' Hansen said. Some locals would rather not wait around to see how the refinery fares. 'I've been here for about 15 years too long,' said Barbara Dumas in Vacherie. 'I'm ready to move back home to some fresh air.'
