This standard is applicable to the management of emission of water pollutants
and air pollutants in existing synthetic resin industrial enterprises or production
facilities, as well as the environmental impact assessment of synthetic resin
industrial construction projects, the design of environmental protection facilities,

implements the “Emission standards for pollutant of petrochemical industry”,
the production equipment of polyvinyl chloride resin (PVC) implements the
“Emission standards for emission of caustic soda and polyvinyl chloride
industry”.
This standard applies to the discharge of pollutants permitted by law. For the
selection of location of the newly-established pollution sources and the
management of the existing pollution source within the specially protected
regions, it shall follow the relevant provisions of such laws, regulations and rules
as the Water pollution prevention and control law of the People’s Republic of
China, the Air pollution prevention and control law of the People’s Republic of
China, the Marine environmental protection law of the People’s Republic of
