Foreword
In order to implement “Environmental Protection Law of the People’s Republic of China”,
“Water Pollution Prevention Law of the People’s Republic of China”, “Air Pollution
Prevention Law of the People’s Republic of China” and other laws and regulations; to
protect environment; to prevent pollution; and to promote technical progress and
sustainable development of petroleum refining industry, this Standard is formulated.
This Standard specifies water pollutants, air pollutant discharge limits, monitoring and
supervision management requirements OF petroleum refining industrial enterprises and
the production facilities.
Odorous pollutants discharged and environmental noise of petroleum refining industrial
enterprises shall follow relevant pollutant discharge standards; identification, treatment
and disposal of generated solid wastes shall follow relevant solid waste pollutant control
standards. Supporting power boiler shall follow “Emission Standard of Air Pollutants for
Boiler” or “Emission Standard of Air Pollutants for Thermal Power Plants”.
This Standard is issued for the first time.
Water pollutants and air pollutants emission control shall be based on this Standard - for
new facilities, it is implemented from July 1, 2015; for existing facilities, it is implemented
from July 1, 2017.The relevant provisions in “Integrated Wastewater Discharge Standard”
(GB8978-1996), “Comprehensive Emission Standard of Air Pollutants” (GB16297-1996),
and “Standard of Smoke and Dust Emission for Industrial Kiln and Furnace”
(GB9078-1996) shall not be implemented. Various regions may implement this Standard
earlier than above dates, according to the demand of local environmental protection and
economic and technical conditions, and approved by the People’s Government at the
provincial level.
This Standard is the basic requirements for emission control over water pollutants and air
pollutants for petroleum refining industry. For the items that are not required by local
provincial people’s government, local pollutant emission standards may be developed; for
items that have already been specified in this Standard, local pollutant emission standards
may develop more stringent requirements than this Standard. If the requirements of
environmental impact assessment document or sewage discharge license/permit are
more stringent than this Standard or local standard, then implement in accordance with
officially replied-approved environment impact assessment document or sewage
discharge license/permit.
This Standard is organized and formulated by the Department of Science, Technology and
Standards of the Ministry of Environmental Protection.
Drafting organizations of this Standard. Fushun Research Institute Of Petroleum and
Petrochemicals, and Chinese Research Academy of Environmental Sciences.
This Standard was approved by the Ministry of Environmental Protection on April 3, 2015.
This Standard shall be implemented from July 1, 2015.
This Standard shall be interpreted by the Ministry of Environmental Protection.

This Standard is applicable to emission management of existing pollutants for petroleum
refining industrial enterprises or production facilities; it is also applicable to petroleum
refining industry’s construction projects’ environmental impact assessment, environmental
protection facility design, completion-acceptance inspection of environmental protection,
and water pollutants and air pollutants emission management after being put into
operation.

this Standard; the relevant provisions of GB 20950-2007 shall not be implemented.
This Standard applies to those behaviors of pollutant emissions that are legally permitted.
For site selection of new pollution sources and management of existing pollution sources
within special protection areas, it shall follow “Water Pollution Prevention Law of the
People’s Republic of China”, “Air Pollution Protection Law of the People’s Republic of
China”, “Marine Environmental Protection Law of the People’s Republic of China”, “Solid
Waste Pollution Prevention law of the People’s Republic of China”, “Environmental Impact
Assessment Law of the People’s Republic of China”, and other laws, regulations and
