Doe Run — A Smelting and Refining History

The Herculaneum, Mo., smelter began operating in 1892 and helped the city and its economy grow for more than a century. It served U.S. companies and manufacturers with the lead they needed for batteries, radiation protection and other uses. The smelting and refining facility provided nearly 300 jobs and supported the local community through donations, volunteerism and infrastructure investments.  

Doe Run produces a variety of specialty metal alloys. 

The End of an Era

Doe Run spent millions of dollars on upgrades, engineering and administration control measures to improve the smelter’s environmental performance, and as of October 2012, Doe Run had reduced air emissions, measured at its five ambient air monitors, to be between .01 and 0.51 micrograms of lead per cubic meter of air (µg/m3). In October 2008, the U.S. Environmental Protection Agency (EPA) adopted a new National Ambient Air Quality Standard for lead, lowering the acceptable level of lead in ambient air to 0.15 µg/m3 and stipulating that measurements be reported as a rolling three-month average. Continuing to upgrade the aging facility to meet the stringent environmental regulation for primary lead smelters was not economically feasible. In 2010, Doe Run reached a comprehensive settlement with the EPA and the state of Missouri. As part of that settlement, Doe Run agreed to cease its smelting operations in Herculaneum at the end of 2013.  

Today’s Operations

Doe Run continues to operate its refinery, strip mill, and alloying and casting operations at Herculaneum. Doe Run’s Resource Recycling facility in Boss, Mo., will continue to produce premium secondary lead metal from recycled lead. 

Repurposing the Herculaneum Site

Doe Run supports the repurposing of the Herculaneum site in conjunction with developers who recognize the property’s strategic location on the Mississippi River. In March 2012, Riverview Commerce Park LLC announced intentions to to purchase and develop approximately 350 acres of Doe Run property. The project is expected to bring together a cluster of light industrial companies offering multi-modal bulk storage and shipping, renewable energy and alternative fuels. RCP began Phase 1 of the port development in 2013, modifying the existing rail and barge loading facilities for shipping.

Doe Run is working hard to prepare the site for future use in a responsible manner. Doe Run has submitted a plan to remediate the smelter site to the EPA and is awaiting approval.
