National Emission Standards for Hazardous Air Pollutants for Wool Fiberglass Manufacturing; Rotary Spin Lines Technology Review and Revision of Flame Attenuation Lines Standards

概要

This action completes the final residual risk and technology reviews (RTR) that the Environmental Protection Agency (EPA) conducted for the Wool Fiberglass Manufacturing source category regulated under the national emission standards for hazardous air pollutants (NESHAP). In this action, the EPA is readopting the existing emission limits for formaldehyde, establishing emission limits for methanol, and a work practice standard for phenol emissions from bonded rotary spin (RS) lines at wool fiberglass manufacturing facilities. In addition, the EPA is revising the emission standards promulgated on July 29, 2015, for flame attenuation (FA) lines at wool fiberglass manufacturing facilities by creating three subcategories of FA lines and establishing emission limits for formaldehyde and methanol emissions, and either emission limits or work practice standards for phenol emissions for each subcategory of FA lines.
