EPA tells Missouri to revamp lead pollution plan

By Kevin Lavery, KWMU

St. Louis – The EPA is telling the Missouri Department of Natural Resources to revamp its plan for attaining the national air quality standard for lead particles.

The requirement applies to the state's oversight of the Doe Run lead smelter in Herculaneum.

A network of air monitors there recorded lead emissions above the national threshold during the first three quarters of 2005.

DNR's John Rustige says the smelter has had numerous "irregular operations" that may be contributing to the pollution.

"When a belt breaks, or when they lose power to a unit; those sorts of things. And the lead standard in a concentration sense is so small, some of these sorts of things can cause problems."

The EPA mandate gives the state one year to revise its plan.
