## Abstract

On April 22, 2004, the EPA issued national emission standards to control hazardous air pollutants emitted from iron and steel foundries. This action amends the work practice requirements for materials certification and scrap selection/inspection programs. The direct final amendments add clarification and flexibility but do not materially change the requirements of the rule.
