noise generating activities are underway:
¡P
One
set of measurements between 0700 and 1900 hours on normal weekdays.
¡P
One
set of measurements between 1900 and 2300 hours on normal weekdays and 0700 and
2300 hours on public holidays.
¡P
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 ¡V
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

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.
4.2.3. All
relevant data including temperature, pressure, 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.
Sampling Procedure and
Monitoring Equipment
4.2.5. High

6.0.1. The Event

6.1.1.
No exceedance was recorded at ACL3 ¡V City
Hall in this reporting month.
6.2.1. No limit
level exceedance was recorded at ACL1 ¡V City Hall and ACL2 ¡V 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 ¡V Central ¡V Wan Chai Bypass at Wan Chai East (CWB Tunnel).
7.0.2.
According to the Monthly EM&A report (May
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 June 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 at TS4 and deep excavation at TPCWAE TCBR1W. 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.
8.0.1.
Five site inspections for Contract no. HK/2012/08 was carried out
on 28 May 2013, 4, 11, 18 and 28 June 2013 in the reporting month. The results
