When the St. Joseph Lead Co. finished work on its 350-foot smoke stack in 1892, the mining company’s pact with tiny Herculaneum, Missouri, was sealed. The town would enjoy more than a century of good-paying jobs while the plant belched sulfur-laced emissions.
Three decades after discovering the town’s blessing was life-threatening, its toxic partnership ends next week when the largest and last lead smelter in the U.S. shuts down.
The Dec. 31 closing of the smelter on the west bank of the Mississippi River, south of St. Louis, marks the end of an era in a region that has supplied most of the nation’s lead since the 1700s. Almost always, the roads and rails from the mines in southeast Missouri’s lead belt ran to Herculaneum.
“Never thought it would go away,” said Herculaneum Mayor Bill Haggard, nodding toward the smelter whose stack is now 550 feet tall, about the height of the Washington Monument. While lead mining continues in Missouri, the halt of smelting echoes the economics that contributed to the decline of high-sulfur coal excavation in the Midwest.
