Foreword
In order to cooperate with the implementation of GB 16297-1996 Comprehensive
Emission Standard of Air Pollutants, and to further standardize the technical requirements
for fugitive emission monitoring of air pollutants, this standard is formulated.
This standard is linked up to Annex C of GB 16297-1996. Starting from the migration
diffusion rules of air pollutants; and combining with various specific conditions of fugitive
emission, this standard provides further regulations and guidance to the simple
determination of meteorological conditions; determination of the suitability degree of
meteorological conditions; and the selection of the monitoring period, the setting methods
of monitoring site, etc.
This standard applies to Environmental Monitoring Station to implement the supervision
and monitoring to the stationary pollution source of fugitive emission; and the monitoring
of completion acceptance of construction project environmental protection facilities. It is
also applicable to the monitoring of stationary pollution source to perform
self-management.
The standard was proposed by Department of Science, Technology and Standards of
Ministry of Environmental Protection of the People’s Republic of China.
The standard was responsibly drafted by Shanghai Environmental Monitoring Center, and
Shanghai Institute of Meteorological Science.
The State Environmental Protection Administration is responsible for the interpretation of
this standard.
Standards of State Environmental Protection Administration
Technical guidelines for fugitive emission monitoring of air pollutants
1 Subject content and scope of application
1.1 Subject content
This standard specifies the regulations and guidance to setting methods of fugitive
emission monitoring point; the determination and selection of monitoring meteorological
conditions; the calculation of the monitoring results, etc. It is the supplement and detailed
document of Annex C of GB 16297-1996 Comprehensive Emission Standard of Air
Pollutants.
1.2 Scope of application
1.2.1 This standard applies to Environmental Monitoring Department to implement the
supervision and monitoring to the stationary pollution source of fugitive emission, for the
purpose of implementing Annex C of GB 16297-1996. It is also applicable to various
pollution source’s organizations to perform the similar monitoring for self-management.
1.2.2 This standard is a technical guidance document. The environmental monitoring
department shall implement the relevant regulations and requirements of this standard in
accordance with the regulations and principles specified in Annex C of GB 16297-1996,
with reference to the specific circumstances and needs.
1.2.3 The setting of the fugitive emission monitoring points for air pollutants generated
from industrial furnace, coke oven and cement plant shall still be in compliance with the
emission standard of air pollutants specified in GB 9078-1996, GB 16171-1996; and GB
4915-1996. The remaining relevant issues are implemented in accordance with the
provisions of this standard.
2 Reference standards
The provisions contained in the following standard may, through the reference in this text,
constitute part of this standard.
GB 16297-1996 Comprehensive Emission Standard of Air Pollutants
5.2 Basic situation investigation of monitored fugitive emission source
In addition to the categories and emission rate (estimated value) of emission pollutants, it
shall also investigate the shape, size, height and the specific location in the building of the
exhaust port of the fugitive emission source. There shall be photos of the exhaust port and
the building.
5.3 Meteorological data investigation of emission source region
Under general situation, the local “all year round” meteorological data can be known from
the meteorological observatory (station) of monitored pollution source, including.
-- Monthly predominant wind-direction and wind-direction frequency;
-- Monthly average wind-speed and the maximum and minimum wind-speed;
-- Monthly average temperature and temperature changes and other situations.
If possible, it is the best to understand the local temperature inversion and atmospheric
stability and other variations of meteorological elements of pollutants.
To understand the local "all year round" meteorological data is to guide the selection of
monitoring period.
5.4 Preparation of instruments, equipment and monitoring data
5.4.1 Preparation of monitoring data
GB 16297-1996 and this standard are the leading technical basis for the fugitive
emissions monitoring. In the standard analysis methods for pollutants from stationary
sources, the sampling methods and sample analysis method related to fugitive emission
are the most important method basis, so the relevant contents shall be read and
understood before monitoring.
5.4.2 Preparation of simple determining instruments of wind-direction and wind-speed on
site
Usually the three-cup portable anemorumbometer may be used. It may also adopt other
portable anemorumbometer with the same function.
The performance of instrument shall be verified by the Metrological Supervision
Department. And necessary commissioning and inspection shall be implemented before
use.
5.4.3 Preparation of sampling instruments and reagent.
Make preparation in accordance with the instrument-equipment and reagent specified in
the sampling section related to the fugitive emission monitoring in the standard analysis
7.4.4 Determining the boundary of eddy area by sight
Make ready for suitable artificial smoke source (for example, using incense stick with
appropriate size). Place it in the upwind of the eddy boundary. Observe the movement of
the smoke-flow by naked eyes to determine the boundary of the eddy zone.
8 Classification of suitability degree of each
meteorological factor to fugitive emission monitoring
8.1 Classification method of suitability degree
It is classified into four classes based on the value of each meteorological factor.
Class a. It is adverse to the diffusion and dilution of pollutants. It is suitable for carrying
out fugitive emission monitoring;
Class b. It is less adverse to the diffusion and dilution of pollutants. It is relatively
suitable for carrying out fugitive emission monitoring;
Class c. It is conducive to the diffusion and ......
