Standard for Fugitive Emission of Volatile Organic
Compounds
1 Scope
This Standard specifies the fugitive emission control requirements for VOCs-
containing materials storage; the fugitive emission control requirements for VOCs-
containing materials transferring and transportation; the VOCs fugitive emission
control requirements in the technology process; the control requirements for
equipment and pipeline components VOCs leakage; control requirements for open
liquid surface VOCs fugitive emission; as well as the requirements for the exhaust gas
collection and treatment system of VOCs fugitive emissions; and the requirements for
pollution monitoring in and around the enterprise plant.
This Standard is applicable to the management of VOCs fugitive emission of existing
enterprises or VOCs fugitive emission of production facilities; the environmental impact
assessment, design of environmental protection facilities, environmental protection
acceptance of completion, and review of pollution emission permits for the construction
projects involving VOCs fugitive emission; as well as the management of VOCs fugitive
emission after the project is put into production.
The industry pollutant emission standards issued by the state have stipulated the
VOCs fugitive emission control; and they shall be implemented in accordance with the
industry pollutant emission standards.
If, due to the safety factors or special process requirements, the requirements for the
VOCs fugitive emission specified in this Standard cannot be met, other equivalent
pollution control measures may be taken and report to the local ecological environment
authority or be implemented in accordance with the relevant requirements of the
pollutant emission permit.

3 Terms and Definitions
For the purpose of this Standard, the following terms and definitions apply.
3.1 Volatile organic compounds (VOCs)
Organic compounds that participate in atmospheric photochemical reactions, or
organic compounds determined in accordance with relevant provisions.
When characterizing the overall emissions of VOCs, according to industry
characteristics and environmental management requirements, total volatile organic
compounds (expressed in TVOC) and non-methane hydrocarbons (expressed in
NMHC) may be used as pollutant control items.
3.2 Total volatile organic compounds (TVOC)
Use the prescribed monitoring method to measure the individual VOCs in the exhaust
gas; sum them together to obtain the total amount of VOCs; it shall be calculated by
the mass concentration of the individual VOCs. In actual work, the individual VOCs
that account for more than 90% of the total amount shall be measured and summed
according to the expected analysis results.
3.3 Non-methane hydrocarbons (NMHC)
Use the prescribed monitoring method, the total amount of gaseous organic
compounds other than methane that the hydrogen flame ionization detector responds
are measured by the mass concentration of carbon.
3.4 Fugitive emission
Air pollutants are emitted randomly without passing through the exhaust tube, including
the escape of open workplaces, and the emission through gaps, vents, open doors
and windows, and similar openings (holes), etc.
3.5 Closed/close
The state or operating method of the pollutant that does not come into contact with the
ambient air, or is isolated from the ambient air through sealing materials and sealing
equipment.
3.6 Closed space
A closed area or closed building formed by a complete enclosure structure to block the
pollutants, workplaces, etc. from the surrounding space. In this closed area or closed
building, except for the entry and exit of personnel, vehicles, equipment, and materials,
as well as exhaust pipes and vents established by law, doors, windows, and other
the primary seal, and the upper seal is called the secondary seal.
3.13 Vapor balancing system
A gas communication and balancing system installed between the loading facility and
the storage tank or between the storage tanks.
3.14 Leakage detection value
Use the prescribed monitoring method, the net value of the VOCs concentration of the
leak points of the equipment and pipeline components detected by the testing
instrument after deducting the environmental background value, which is expressed in
mole fraction of carbon.
3.15 Open recirculating cooling water system
A circulating cooling water system in which circulating cooling water directly contacts
the atmosphere to dissipate heat.
3.16 Existing facility
Industrial enterprises or production facilities that have been completed and put into
operation before the implementation of this Standard, or whose environmental impact
assessment documents have been approved or filed.
3.17 New facility
Since the date of implementation of this standard, the environmental impact
assessment documents have been approved or filed for new, rebuilt and expanded
industrial construction projects.
3.18 Key regions
In accordance with the requirements of environmental protection work, regions that
have serious air pollution, fragile ecological environment, or need for further
environmental air quality improvement, and require strict control of air pollutant
emission.
3.19 Stack height
The height from the ground where the exhaust tube (or its main building structure) is
located to the exhaust tube outlet, in m.
3.20 Enterprise boundary
The legal boundary of an enterprise or production facility. If it is difficult to determine
the legal boundary, it refers to the actual land occupation boundary of the enterprise
or production facility.
used between the floating roof and the tank wall. For outer floating roof tanks,
double seals shall be used between the floating roof and the tank wall; and the
prime seal shall adopt high-efficiency sealing methods such as liquid-mounted
seal and mechanica...
