2016-16450: National Emission Standards for Hazardous Air Pollutants: Ferroalloys Production

Summary

On June 30, 2015, the Environmental Protection Agency (EPA) published the residual risk and technology review (RTR) final rule, establishing national emission standards for hazardous air pollutants (NESHAP) for the Ferroalloys Production source category. Subsequently, the EPA received two petitions for reconsideration of certain aspects of the final rule. The EPA is announcing reconsideration of and requesting public comment on three issues raised in the petitions for reconsideration, as detailed in the SUPPLEMENTARY INFORMATION section of this action. The three issues the EPA is reconsidering and seeking public comment on are the following: the polycyclic aromatic hydrocarbons (PAH) compliance testing frequency for furnaces that produce ferromanganese (FeMn); the use of the digital camera opacity technique (DCOT) for determining compliance with the shop building opacity standards; and the use of bag leak detection systems (BLDS) on positive pressure baghouses. The EPA is seeking comment only on these three issues and will not respond to comments addressing other issues or other provisions of the final rule. The EPA is not proposing any changes to the NESHAP in this document.
