Foreword
To implement the laws and regulations such as “Environmental protection law
of the People’s Republic of China”, “Water pollution prevention and control law
of the People’s Republic of China”, “Air pollution prevention and control law of
the People’s Republic of China”, to protect environment and prevent and control
pollution, to promote technological progress and sustainable development in
the synthetic resin industry, this standard is hereby developed.
This standard specifies the emission limits, monitoring, supervision and
management requirements for water pollutants and air pollutants in industrial
enterprises and their production facilities of synthetic resins (except for polyvinyl
chloride resins).
For the synthetic resin industrial enterprise’s emission of odorous pollutants and
environmental noises, the corresponding national pollutant discharge
standards apply. For the identification, treatment and disposal of solid wastes,
the corresponding national solid waste pollution control standards apply. The
supporting boiler and heat-transfer oil-furnace follows the “Emission standard
of air pollutants for boilers”.
This standard is the first release.
Starting from July 1, 2015 for the new facility, and from July 1, 2017 for the
existing facility, the emission of water pollutant and air pollutant shall be
controlled in accordance with the provisions of this standard, at the same time
it will stop implementing the relevant provisions of the “Integrated wastewater
discharge standard” (GB 8978-1996) and the “Comprehensive emission
standard of air pollutants” (GB 16297-1996). Each region may, in accordance
with the local environmental protection needs as well as the economic &
technical conditions, implement this standard in advance after being approved
by provincial people’s government.
This standard provides the basic requirements for the control of emission of
water pollutants and air pollutants in synthetic resin industry. For the items
which are not specified in this standard, the local provincial people's
government may formulate local pollutant discharge standards; for the items
which have been specified in this standard, the local provincial people's
government may formulate local pollutant discharge standards that are stricter
than this standard. Where the requirements of environmental impact
assessment or the discharge permit are stricter than this standard or local
standard, it shall be implemented in accordance with the approved
environmental impact assessment or discharge permit.
This standard was formulated by the Science and Technology Standards
Department of the Ministry of Environmental Protection.
Drafting organizations of this standard. China Petroleum and Chemical
Exploration and Design Association Environmental Protection Design
Committee, China Tianchen Engineering Co., Ltd., Zhonglan Lianhai Design
and Research Institute.
This standard was approved by the Ministry of Environmental Protection on
April 3, 2015.
This standard is implemented from July 1, 2015.
For this standard, the Ministry of Environmental Protection shall be responsible
for its interpretation.
Emission standard of pollutants
for synthetic resin industry
1 Scope
This standard specifies the emission limits, monitoring, supervision and
management requirements for water pollutants and air pollutants from synthetic
resin industrial enterprises and their production facilities (including the
enterprises for synthetic resin processing and waste synthetic resin recycling
and processing as well as their production facilities).
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,
the completion environmental protection acceptance, and the management of
emission of water pollutant and air pollutant after it is put into operation.
The monomer production equipment in the synthetic resin enterprise
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
China, the Law of the People's Republic of China on environmental pollution by
solid wastes, the Law of the People's Republic of China on environmental
impact assessment.

raw material, to produce the synthetic resin through a polymerization
reaction to form macromolecule, or industry which uses the common
synthetic resin as the raw material, to produce new synthetic resin product
through such methods as modification. It also includes the industries which
use the synthetic resin as raw material to produce synthetic resin products
by such methods as extrusion, injection, pressing, calendering, foaming, etc.,
