2.1
At least three independent
trained personnel/competent persons shall be selected to form an odour panellist
to conduct the odour patrol after participated in a set of screening tests at the Odour Research Laboratory
in the Hong Kong Polytechnic University or in other qualified laboratories. The qualified odour patrol members have their individual n-butanol
thresholds that complied with the requirement of European Standard Method
(EN13725) in the range of 20 to 80 ppb/v. In addition, the patrol members shall also:-
Ø Be at least 16 year of age and
willing and able to follow instructions;
Ø Be free from any respiratory
illnesses.
Ø Be engaged for a sufficient
period to build up and monitor/detect at several monitoring location;
Ø Prohibited to smoke, eat, drink
(except water) or use chewing gum or sweets 30 min before and during odour
intensity analysis;
Ø Take great care not to cause any
interference with their own perception or that of others by lack of personal
hygiene or the use of perfumes, deodorants, body lotions or cosmetics;
Ø Not communicate with each other
about the results of their choices.
2.2
Certificates of the qualified
Odour Panel Members have been provided in Appendix
A.
2.3
During the patrol, the patrol
members shall conduct
the odour intensity analysis at the downwind locations subject to the
prevailing weather forecast condition. Depending on the distance between the
SCISTW/PTWs and monitoring locations, the sequence would generally start from the
least odorous locations to stronger odorous locations. The main odour emission
sources and the areas to be affected by the odour nuisance shall be identified
and recorded on the Data Record Sheet.
2.4
The odour intensity should be
determined at 5 different levels according to the criteria below:
0 - Not
detected. No odour perceived or an odour so weak that it cannot be easily characterised
or described;
1 - Slight Identifiable odour, and slight chance to have odour nuisance;
2 - Moderate Identifiable odour, and moderate chance to have odour nuisance;
3 - Strong Identifiable, likely to have odour nuisance;
4 - Extreme Severe odour, and unacceptable odour level.
2.5
The odour patrol members shall record the following findings at each locations:
Ø
The wind direction;
Ø
The local wind speed;
Ø
Odour intensity;
Ø
Odour nature;
Ø
Potential odour source.
2.6
On-site conditions shall be recorded during the monitoring period:
Ø Meteorological data such as daily
average temperature, daily average humidity, wind speed and direction on the
surveyed day from the nearest Hong Kong Observatory Weather Station;
Ø Records of any abnormal
operations near the monitoring stations and route during the odour patrol.
2.7
The odour patrol shall be conducted at the height
of 1.5m from the ground surface at the existing ASRs as shown in Table 2.1 and at the DSD facilities’ site
boundary. Figure
1-10 illustrated
the locations of the ASRs and site boundary.

Thermo-Anemometer: The
meter capable of record up to 2-hour air velocity averaging for measurements
and temperature measurement via built-in thermistor.
2.12
The clockwise rotation of the blade of the
Thermo-Anemometer would indicate the downwind condition when it is pointed to
the SCISTW/PTWs.
2.13
Patrol member will point the Thermo-Anemometer
to the SCISTW/PTWs. During downwind condition, the blade of the
Thermo-Anemometer will rotate clockwise. Otherwise, it will be recorded as an
upwind condition.
2.14
The wind direction will be recorded based on a
compass.
2.15
Thermo-Hydrometer: The
meter capable of record relative humidity between 25%RH and 95%RH. Comfort
indicators will display the level of comfort as comfortable, wet or dry.

(including temperature, wind speed, wind direction, relative humidity) from the
nearest Hong Kong Observatory’s Weather Stations for each of the odour patrols
were provided for reference in Appendix

2.19
The odour intensities detected
around the SCISTW were found to be ranging from level 0 up to level 3, while the
