Final Amendments: Air Toxics Standards for Paper and Other Web Coating - Risk and Technology Review

On March 11, 2020, EPA finalized minor amendments to the 2002 Paper and Other Web Coating (POWC) National Emission Standards for Hazardous Air Pollutants (NESHAP). EPA evaluated the risks remaining after fully implementing the NESHAP and determined that risks from the POWC source category are acceptable. In addition, the agency identified no developments in practices, processes or control technologies that would further reduce emissions of hazardous air pollutants. The EPA finalized no significant changes to the original NESHAP for these source categories as a result of the RTR and has determined the standards continue to provide an ample margin of safety to protect public health and the environment.

The EPA also finalized minor amendments to the existing regulation. These proposed amendments clarify that the standards are applicable during periods of startup, shutdown and malfunction (SSM); require periodic emissions testing; and require electronic reporting of compliance reports, notifications and performance test results. The proposed amendments also provide more flexibility for monitoring requirements and provide regulatory clarity. These minor amendments are proposed to go into effect 365 days from promulgation.
