New MACT Standards Proposed for Polyvinyl Chloride and Copolymers Production

摘要

On May 20,2011 (76 FR29528-29607), EPAproposed maximum achievable control technology (MACT) standards for polyvinyl chloride (PVC) and copolymers production. The proposed MACT standards replace standards previously issued for this source category that were vacated by the court. The proposed standards would apply to both major and area source PVC and copolymers production facilities, and would establish emission limits for vinyl chloride, hydrogen chloride (HC1), total hazardous air pollutants (HAPs), and dioxins/furans. Major sources are facilities with the potential to emit 10 tons per year (tpy) or more of any single HAP, or 25 tpy or more of any combination of HAPs. Area sources are facilities that are not major sources. Area source PVC and copolymers production facilities are currently regulated under 40 CFR Part 63, Subpart DDDDDD.
