In accordance with the approved EM&A
Manuals, 24-hour Total Suspended Particulates (TSP) monitoring at the
designated air quality monitoring station is required. Impact 24-hour TSP monitoring
should be carried out at least once every 6 days. In case of complaints, 1-hour
TSP monitoring should be carried out at least 3 times per 6 days when the
highest dust impacts are likely to occur.
2.1.2
The monitoring
equipment, monitoring methodology and monitoring schedule are detailed in the
monthly EM&A Reports for EP-451/2013 prepared for
Contract No. ED/2018/04.
2.2.1
According to the EM&A Manual, three air
quality monitoring locations, namely KTD1, KTD2 and KER1, are covered by this
Contract within the South Apron Area of Former Kai Tak
Airport. The other two air quality monitoring locations, which are identified
in Cha Kwo Ling area, are farther than 500m away from

ED/2018/04.
2.2.2
According to the approved alternative baseline
air quality and noise monitoring locations (EPD reference: EP2/K19/A/21 pt.5),
the original monitoring locations (KTD1, KTD2 and KER1) are proposed to be
replaced by alternative monitoring locations (KTD1a, KTD2a and KER1a) for air
quality monitoring.
2.2.3
According to the approved relocation of
monitoring location KER1a (EPD reference: () in EP2/K19/A/21 pt.5), the
monitoring location KER1a are proposed to be relocated by alternative
monitoring location KER1b for air quality monitoring.
2.2.4
According to the approved relocation of
monitoring location KTD2a (EPD reference: () in EP2/K19/A/21 pt.6), the
monitoring location KTD2a are proposed to be relocated by alternative
monitoring location KTD2b for air quality monitoring.
2.2.5
According to the approved relocation of
monitoring location KTD2b (EPD reference: () in EP2/K19/A/21 pt.7), the
monitoring location KTD2b are proposed to be relocated by alternative
monitoring location KTD2c for air quality monitoring.
2.2.6
As informed by the ET
of Contract No. ED/2018/04, the monitoring location KTD1a and KER1b have been
relocated to KTD1 and KER1 for air monitoring on 3 August 2020.
2.2.7
The most updated locations are summarized in Table 2.1
and shown in Figure 2.
2.3.1 The monitoring results and observations for
KTD1, KTD2c and KER1 are reported in the Monthly EM&A Reports for
EP-451/2013 prepared for Contract No. ED/2018/04.
2.3.2 No Action / Limit Level exceedance was
recorded for 24-hr TSP at KTD1, KTD2c and KER1 in the reporting month.
2.3.3 No complaint of air quality was received. Therefore, no impact 1-hour TSP
monitoring was conducted in the reporting month.
2.3.4 The weather conditions during the monitoring are provided in Appendix F.
