Polyvinyl Chloride and Copolymers Production: National Emission Standards for Hazardous Air Pollutants (NESHAP) - 40 CFR 63 Subparts J & HHHHHHH

On this page:

Rule Summary

The polyvinyl chloride (PVC) and copolymers production source category includes any facility which manufactures polymerized vinyl chloride. Polyvinyl chloride may be produced by the suspension, mass emulsion/dispersion and solution processes, although other methods may be used.

These national emission standards for hazardous air pollutants (NESHAP) apply to new and existing sources at polyvinyl chloride and copolymer (PVC) production facilities. PVC standards were developed for both major and area sources.  The EPA determined that hazardous air pollutants (HAP) such as vinyl chloride, vinylidene chloride (1,1 dichloroethylene), and vinyl acetate are emitted during the production of PVC emits .

These rules establish emission limits and work practices for process vents, process wastewater, stripped resins, equipment leaks, storage vessels and heat exchange systems located at PVC production facilities.

EPA has classified vinyl chloride as a known human carcinogen and vinylidene chloride as a possible human carcinogen. All of these HAP can cause noncancer health effects in humans.

See the regulations below for more details.
