Chemetco was a major U.S. secondary copper smelter in Hartford, Illinois, that operated from 1969 until 2001. At its peak, the facility produced about 125,000 tonnes of refined copper annually from recycled material, which represented a major proportion of domestic secondary copper refining capacity. The company reported revenues of roughly $500 million in 1999.
Chemetco and its senior officers became involved in multiple federal investigations during the 1990s. In 1992, the Federal Election Commission found that Chemetco, as well as its company president, John M. Suarez, and associate José Bóveda, arranged unlawful corporate and foreign campaign contributions affecting the U.S presidential primary in Missouri. The FEC's General Counsel described the payments as "clearly laundered money," and evidenced that funds were routed through entities owned by Chemetco and a Belgian holding company.[1] Suarez took over ownership of the company the following year.[1]
In 1996, an inspector from the Illinois EPA discovered a concealed 10-inch pipe discharging heavy metals from the smelter into wetlands connected to the Mississippi River. The finding led to a joint investigation by the U.S EPA, FBI, and Illinois State Police, leading to federal indictments against the company and its chief officer, Denis L. Feron, who owned parent company Metallo Chimique. Prosecution and conviction followed, for conspiracy and felony violations of the Clean Water Act. After Chemetco entered a nolo contendere ("no contest") plea, the company was fined $3.8 million, then ceased operations in 2001, following Chapter 7 bankruptcy.
The case established legal precedent when the Seventh Circuit held in United States v. Chemetco, Inc. that the number of violation days is a sentencing factor for judges, rather than a matter for a jury. Atmospheric modeling later identified Chemetco as one of the largest individual North American sources of dioxins in the Arctic, including measurable fallout in Nunavut, Canada.[2] Federal investigations also documented extensive worker exposure to health problems including chronic beryllium disease and hazards such as widespread lead overexposure.[3]
The former Chemetco site was made a Superfund cleanup project in 2010 and remains under oversight by the EPA. Remediation continues to address contaminated soils, slag, and hazardous waste; at the same time, ongoing litigation involves numerous Potentially Responsible Parties including Fortune 500 companies.
Location, history and operations
38.835°N, -90.095°W
Location
The Chemetco smelter was in Hartford, Illinois, one mile east of the Mississippi River, within Madison County's American Bottom floodplain. The facility occupied roughly 41 acres of a 230-acre tract.[4][5]
History
Construction of the plant, originally with the name Chemico, began in 1969. Three 70-ton gas-fired converters were installed, and a fourth later. For each converter, there was also a melting furnace.
The business was incorporated as a Delaware company and renamed Chemetco, Inc. in 1972.[6]
Ownership
1992 U.S presidential primary 'laundered money' campaign contributions
In June 1992, a year before John M. Suarez took over as Chemetco's owner, a complaint was filed with the Federal Election Commission alleging that contributions connected to Chemetco's president, John Suarez, and associate José Bóveda, violated federal election law. A contemporaneous The Kansas City Star profile of Suarez had noted his history of political contributions and that some donations were made through companies or associates rather than in his own name.[8]
The FEC complaint stated that the contributions affected '...an ongoing primary election campaign which will end on August 4, 1992', referring to the U.S presidential primary then underway in Missouri.[9]
In 1994, the FEC investigated allegations that Suarez arranged a $25,000 contribution through an account under the name Tippins Development Ltd., which was refunded amid concerns over its legality.[10] Additional contributions from Concorde Trading, Chemetco, and Midco, all of which were linked to Suarez and a Belgian holding company, were also routed to federal campaigns through intermediaries.[11]
Chemetco's role in U.S. secondary copper industry collapse
The permanent closure of Chemetco's facility in 2001 signaled the end of large-scale secondary copper smelting in the United States. The company ceased operations on October 31, 2001, following criminal convictions for environmental violations and mounting financial pressures, and Chemetco then filed for Chapter 7 bankruptcy protection on November 13, 2001.[15][16] The plant had an output of 95,000 metric tons and was operating at roughly 30% below capacity before closure.
Secondary smelters operated by Southwire, as well as Cerro Copper Products' facility, had already shut down.[17] Between 1997 and 2001, when Chemetco closed down, approximately 200,000 metric tons of secondary refining capability vanished; output in the United States fell to zero.[18]
Chemetco's exit was the final point in a cycle of closures mediated by market pressures as well as the substantial capital investments required to meet evolving environmental standards that operators found economically unviable.[19]
Operation
Main products
Chemetco was primarily a secondary smelter of copper anodes and cathodes. Its peak historic capacity was about 125,000 tonnes of refined copper annually, from an average of 250,000 tonnes of scrap copper and residues.[20]
Subsidiary products and precious metals
The smelter also produced lead and tin ingots. Independent evaluations of the tankhouse sludges confirmed gold, silver, and other metals.[21]
Introduction of Kaldo /Top-blown rotary converter (TBRc) technology to secondary copper smelting
Chemetco appears to mark the first large-scale, continuous application of TBRc in secondary copper refining rather than steel, showing parent company Metallo to be an early adopter
Occupational health hazards
Systemic occupational health deficiencies
The findings of the NIOSH Health Hazard Evaluation showed profound and systemic failures in occupational health protection at Chemetco. Documented overexposures to arsenic, lead, and sulfuric acid, combined with contamination of eating areas, demonstrated that the facility lacked effective exposure controls and hygiene measures.
NIOSH concluded that worker exposures exceeded recognized safety limits for multiple hazardous substances, and these resulted in adverse health effects including respiratory irritation, skin damage, beryllium sensitization and chronic beryllium disease and elevated blood lead levels. These findings indicated that Chemetco fell very short of fundamental occupational health and safety standards.
Chronic beryllium disease
NIOSH investigators confirmed one case of chronic beryllium disease in a 31-year-old furnace operator who had worked at the plant for two and a half years. The worker was diagnosed with chronic berylliosis requiring lifelong steroid treatment.[26]
The affected worker was found to be charging small quantities of metal scrap into a sample furnace without respiratory protection, and further, his job classification did not require such equipment.
Labor relations
In 1996, Geri Heinemeier (née Champion) filed a lawsuit against two companies, Chemetco, Inc. and Tri-Me Transportation, Inc., claiming she was sexually harassed, discriminated against because of her age, and fired in retaliation after reporting the harassment.
Heinemeier v. Chemetco, Inc. (246 F.3d 1078 (7th Cir. 2001)) was a decision of the United States Court of Appeals for the Seventh Circuit concerning joint-employer liability under Title VII of the Civil Rights Act of 1964 and the Age Discrimination in Employment Act. The court held that factual disputes about shared control of employment conditions prevented summary judgment. Instead, they required a jury to decide whether both companies concerned functioned as the plaintiff's employers.
Before the case went to trial, the district court had ruled in favor of Chemetco, deciding that it could not be held responsible because Heinemeier was legally employed by Tri-Me, not by Chemetco. The rest of the case continued against Tri-Me alone, and a jury found in Heinemeier's favor. She was awarded about $411,000 in damages for sexual harassment and in retaliation.
Heinemeier then appealed the ruling that had originally dismissed Chemetco from the case. The United States Court of Appeals for the Seventh Circuit agreed with her, finding that there was enough evidence for a jury to decide whether Chemetco and Tri-Me both acted as her employers. The appeals court sent the case back to the district court for further proceedings.
The appellate court explained that a company can be treated as an employer even if it does not issue paychecks, if it shares control over pay, benefits, or working conditions. It found that Chemetco and Tri-Me were closely connected in their operations, and that a jury could reasonably find that both companies employed Heinemeier under the 'economic reality' test used in employment discrimination cases.[29]
Environmental problems
Long before an illegal waste pipe was uncovered, Chemetco already had a thick compliance file. EPA and IEPA documents describe repeated violations through the 1980s and early 1990s. One EPA briefing put it plainly: "... a long history of criminal and civil environmental noncompliance."[30]
Water
Acting on an anonymous tip-off from a security guard, on 18 September 1996, an Illinois EPA inspector found a concealed 10-inch pipe with water bubbling up from it in a ditch near the truck parking lot. EPA and IEPA came to the conclusion that it had been in use since the mid-1980s to carry process water and metal-laden runoff into Long Lake, which drains toward the Mississippi River.[31] Under the Clean Water Act, it is a felony to pollute a navigable waterway.
Samples taken at multiple sites showed cadmium, copper, lead, and zinc and many other metals of concern at highly elevated levels. Investigators and prosecutors concluded that the pipe had been used to dispose of the accumulating piles of 'zinc oxide', which had been debarred from being sold as a recyclable material and instead, tagged as a hazardous waste.
Impact and legacy
Geochemical research has examined the broader consequences of Chemetco's operations in the St. Louis–Madison County region.[45] There has also been academic study in the field of environmental justice.[45]
Environmental injustice impacts in St Louis Metropolitan area
On a metropolitan scale, Chemetco appeared among facilities analyzed in studies of environmental risk and inequality in the St. Louis region. Those analyses used U.S. EPA Toxic Release Inventory data to map industrial emissions and found that such facilities were concentrated near lower-income communities, raising environmental-justice concerns.[45][46]
The spatial analysis conducted by Abel (2008) identified Chemetco's Hartford smelter among the region's major industrial point sources in the EPA's Toxic Release Inventory dataset.
Prosecution and conviction
Discovery of the concealed discharge
Between 1986 and 1996 Chemetco operated a secondary copper refining facility at Hartford, Illinois, which was later found to have discharged untreated wastewater through a hidden pipe into wetlands leading to the Mississippi River.[47] The pipe was not shown on site diagrams and its exposed sections were covered with straw, but after a tip-off, it was discovered by an Illinois Environmental Protection Agency field manager on September 18, 1996, along with a valve which enabled it to be shut off at the distal end.
The pipe, known to employees as 'the mystery pipe to nowhere', was an open secret within the plant and was used before its discovery by IEPA for about ten years to dispose of toxic waste into nearby wetlands. Its exposure triggered a multi-agency criminal investigation involving the Illinois Environmental Protection Agency, the Environmental Protection Agency's Criminal Investigation Division, the Illinois State Police, the FBI and the U.S. Army Criminal Investigation Command.[48]
Its existence had allowed the plant to bypass permitted outfalls and monitoring systems resulting in unreported releases of heavy metals including lead and cadmium.[49]
Denis L. Feron
Feron served for several decades as Chemetco's president.[54] Before establishing the Hartford plant in 1970, Feron owned Metallo Chimique in Belgium.
In April 1999, Feron and six junior employees acting under his direction were indicted on federal charges for long-term violations of the Clean Water Act.[55] These centered on the concealed pipeline that discharged contaminated wastewater into wetlands near the Mississippi River.[56] Feron did not appear in court and left the United States, remaining abroad during the ensuing proceedings.[57] Because there was no extradition agreement with Belgium, he was at liberty to escape trial.[55]
In December 2008 the U.S. Environmental Protection Agency's Criminal Investigation Division placed him on its 'Most Wanted' fugitives list, describing him as a corporate officer who had evaded prosecution for nearly a decade.
Superfund
The former Chemetco facility was added to the EPA's National Priorities List on March 2, 2010.[59] The listing made the site eligible for long-term cleanup under the federal Superfund program.
Following the company's bankruptcy in 2001, there was no viable owner to carry out cleanup. The U.S. Environmental Protection Agency (EPA) and the Illinois Environmental Protection Agency (IEPA) conducted early stabilization work, including demolition of several structures and fencing off the main industrial area.[60] A 2015 Administrative Order on Consent (AOC) established the framework for a Remedial Investigation and Feasibility Study (RI/FS) to define the contamination and evaluate cleanup options.[61]
The site remains under EPA oversight with restricted access. It still contains large amounts of waste material, including slag and residues from copper smelting operations.[60] Elevated levels of copper, cadmium, lead, and zinc are present in soil, sediment and water on and near the site.[60]
