Doe Run Completes State Implementation Plan

Company meets deadline for completing 60-plus control measures in Herculaneum

St. Louis (PRWEB) May 6, 2008

The Doe Run Company has completed the 60-plus engineering and administrative control measures that were outlined in the revised State Implementation Plan (SIP) for its Herculaneum, Mo., smelter.

The SIP is designed to improve air quality and bring the Herculaneum area into consistent attainment with the National Air Quality Standard for lead. The deadline for completing the SIP work was April 7, which was met by Doe Run’s Herculaneum team.

“The work was completed on time, and we believe the SIP projects will help us meet our goal of consistent attainment of the air quality standard,” said Gary Hughes, general manager of Doe Run’s Herculaneum smelter. “We continue to look for ways to improve our environmental performance, so we view this milestone as part of a larger process.”

The SIP is a process used throughout the United States to improve air quality and help achieve federal air standards – in this case, for lead. The Herculaneum plan outlined more than 60 engineering and administrative control measures that were to be completed over a two-year period at a total cost of approximately $3 million.

Among the projects completed as part of the SIP were:

• A real estate transaction with the city of Herculaneum to create more space between the smelter and neighboring community, and a fence line to mark that space;
• A new blast furnace design to reduce ventilation losses and improve dust capture efficiency;
• Additional enclosures and ventilation projects; and
• Improved materials handling procedures and equipment.
