After meeting federal air quality standards for the first time ever earlier this year, the nation's largest lead smelter was out of compliance during the second quarter. Doe Run Co. said that one of seven air monitors at its Herculaneum plant measured lead in the air above the national standard. If the plant exceeds the standard again, officials say Doe Run will face more expensive restrictions, including possible limits on production.
