Noise Monitoring Parameters, Frequency and Duration
4.1.2.
Continuous 24-hour noise monitoring shall be
carried out at the designated monitoring stations. The following is an initial
guide on the regular monitoring frequency for each station on a 24 hours daily
basis when noise generating activities are underway:
·
One set of
measurements between 0700 and 1900 hours on normal weekdays.
·
One set of
measurements between 1900 and 2300 hours on normal weekdays and 0700 and 2300
hours on public holidays.
·
One set of
measurements between 2300 and 0700 hours on next day on everyday.
4.1.3.
If construction works are extended to include works
during the hours of 1900 – 0700 as well as public holidays and Sundays,
additional weekly impact monitoring shall be carried out during respective
restricted hours periods. Applicable permits under NCO shall be obtained by the
Contractor.
Monitoring Equipment
4.1.4.
As referred to in the Technical Memorandum ™ issued
under the NCO, sound level meters in compliance with the International
Electrotechnical Commission Publications 651: 1979 (Type 1) and 804: 1985 (Type
1) specifications shall be used for carrying out the noise monitoring.
Immediately prior to and following each noise measurement the accuracy of the
sound level meter shall be checked using an acoustic calibrator generating a
known sound pressure level at a known frequency. Measurements may be accepted
as valid only if the calibration level from before and after the noise
measurement agrees to within 1.0 dB.
4.1.5.
Noise measurements shall not be made in fog, rain,
wind with a steady speed exceeding 5 m/s or wind with gusts exceeding 10 m/s.
The wind speed shall be checked with a portable wind speed meter capable of
measuring the wind speed in m/s.
4.1.6.
The sound level meter shall be checked using an
acoustic calibrator generating a known sound pressure level at a known
frequency before deployment to the site and during each site visit.
Measurements will be accepted as valid only if the calibration level from
before and after the noise measurement agrees to within 1.0 dB.
Air Quality Monitoring Stations
4.2.1.
The air monitoring stations for the Project are
listed and shown in Table 4.2 and Figure 4.1.. Appendix

Air Monitoring Parameters, Frequency and Duration
4.2.2.
One-hour and 24-hour TSP levels should be measured
to indicate the impacts of construction dust on air quality. The 24-hour TSP
levels shall be measured by following the standard high volume sampling method
as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part
50), Appendix B.

weather conditions, elapsed-time meter reading for the start and stop of the
sampler, identification and weight of the filter paper, and any other local
atmospheric factors affecting or affected by site conditions, etc., shall be
recorded down in detail.
4.2.4.
For regular impact monitoring, the sampling
frequency of at least once in every six-days, shall be strictly observed at all
the monitoring stations for 24-hour TSP monitoring. For 1-hour TSP monitoring,
the sampling frequency of at least three times in every six-days should be
undertaken when the highest dust impact occurs.

6.1.
6.1.1.
No exceedance was recorded at ACL3 – City Hall in
this reporting month.
6.2.1.
No action or limit level exceedance was recorded at
ACL1 – City Hall and ACL2 – PLA Barracks in this reporting month.
6.3.1.
There was no non-compliance from the site audits in
the reporting period. The observations and recommendations made in each
individual site audit session were presented in Section 8.
6.4.1
There was no particular action taken since no
non-compliance was recorded from the site audits in the reporting period.
7.0.1.
This section addresses the relevant cumulative
construction impact due to the concurrent activities of the current projects
including the Central Reclamation Phase III (CRIII), Wan Chai Development Phase
II (WDII), Central-WanChai Bypass (CWB), Island Eastern Corridor Link projects
(IECL) and Wan Chai Development Phase II – Central – Wan Chai Bypass at Wan
Chai East (CWB Tunnel).
7.0.2.
According to the Monthly EM&A report (June 2013)
of Central Reclamation Phase III (CRIII) for Contract HK 12/02, underground
drainage and footpath construction, modification to the junction of Road D8 and
Road P2 and modification of timber decks at advance promenade were performed in
the July 2013 reporting month. The water quality monitoring was completed in
October 2011 and no Project-related exceedance was recorded for air and noise
monitoring. It can be concluded
that cumulative construction impact due to the concurrent activities of the
current projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 was insignificant.
7.0.3.
According to the construction programme of Wan Chai
Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link
projects, the major construction activity under Wan Chai Development Phase II were
marine works at HKCEC areas, cross-harbour Watermains, Fresh Watermains and
Cooling Watermains Installations, tunnel works at Wan Chai East, ELS work and
pipe roofing works at TS4 and cut and cover tunnel construction at TPCWAE. Excavation
and tunnel works at Central Interchange, ELS and box culvert construction at
North Point area. The major environmental impact was water quality impact at
7.0.4.
The major environmental impacts generated from tunnel
works at Central and tunnel works at Wan Chai East, IECL and Causeway Bay Typhoon
Shelter were undertaken in the reporting month. No significant air impact from
construction activities was anticipated in the reporting month. Besides, no project-related
exceedances were recorded during the air and noise environmental monitoring
events in the reporting month. Thus, it is evaluated that the cumulative
construction impact from the concurrent projects including Wan Chai Development
Phase II was insignificant.
