Monitoring
Requirement
3.1.1 In accordance with the approved EM&A Manuals, Leq
(30min) monitoring is conducted for at least once a week during the
construction phase between 0700 and 1900 on normal weekdays at the designated
monitoring locations.
3.1.2 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.
3.2.1 According to
the EM&A Manual, three noise 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 noise monitoring locations,
which are identified in Cha Kwo Ling area, are
farther than 300m away from the site boundary and thus not covered by this
Contract. The monitoring works in Cha Kwo Ling area
are covered by Contract No. ED/2018/04.
3.2.2 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 noise monitoring.
3.2.3 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 noise monitoring.
3.2.4 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 noise monitoring.
3.2.5 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 noise monitoring.
3.2.6
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 noise monitoring on 3 August 2020.
3.2.7 The most
updated locations are summarized in Table 3.1 and shown in Figure 2.
3.3.1
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.
3.3.2 One Limit Level exceedance for construction
noise was recorded in the reporting month. An exceedance was recorded at KER1
on 30 December 2020.
3.3.3
No Action / Limit Level exceedance was recorded for construction noise at
KTD1 and KTD2c in the reporting month.
3.3.4
On 30 December 2020, at KER1 non-project related construction works were
carried out during Noise monitoring. Noise generated from road traffic along
Kai Hing Road, also generated from construction site
of Trunk Road T2 when sheet piling work and breaking activities were
processing. Thus, it is considered that this exceedance is not project related.
