Final Rule - National Emission Standards for Hazardous Air Pollutants: Refractory Products Manufacturing Residual Risk and Technology Review
The U.S. Environmental Protection Agency (EPA) finalized amendments to the 2003 National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Refractory Products Manufacturing source category. EPA evaluated the risks remaining after fully implementing the NESHAP and determined that risks are acceptable, and the standards provide an ample margin of safety to protect public health and the environment. EPA identified one technology that reflects current industry best practices. As a result, EPA is amending the work practices that are required to minimize air toxics emissions during scheduled maintenance of control devices for continuous kilns.
EPA is finalizing other changes to the original NESHAP for this source category and has determined that the standards continue to provide an ample margin of safety to public health and the environment.
