2.1.1 Wan Chai Development phase II and
Central-Wan Chai Bypass (hereafter called “the Project”) are Designated Project
(DP) under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). The
Environmental Impact Assessment (EIA) Report for Wan Chai Development phase II
and Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) has been approved on
11 December 2008.
2.2.1. The design and construction of Wan
Chai Development Phase II and Central Wanchai Bypass involves the construction
and operation of primary and district distributor roads that is shown at Figure

2.2.2.
The
key purpose of the study area encompasses the Wan Chai harbourfront area. The
area starts at the boundary of Central Reclamation Phase III (CRIII) at the
west and connects to the existing Hung Hing Road at the east.
The scope of the project includes:
·
A dual 2-lane primary distributor road, Road P2,
approximately 0.6km in length; and
·
Other new primary and district distributor roads
connecting to the slip roads of the Central-Wan Chai Bypass with a total length
of approximately 0.7km.
2.2.3. The project also contains various Schedule 2 DP that, under
the EIAO, require Environmental Permits (EPs) to be granted by the
DEP before they may be either constructed or
operated. Table 2.1 summarises the DP under this Project. Figure
2.1 shows the locations of
these Schedule 2 DP.

Noise
Monitoring Parameters, Frequency and Duration
3.1.2. The construction noise level shall be
measured in terms of the A-weighted equivalent continuous sound pressure level
(Leq). Leq (30 minutes) shall be used as the monitoring
parameter for the time period between 0700 and 1900 hours on normal weekdays.
For all other time periods, Leq (5 minutes) shall be employed for
comparison with the Noise Control Ordinance (NCO) criteria.
Supplementary information for data auditing, statistical results such as L10
and L90 shall also be obtained for reference.
3.1.3. Noise
monitoring shall be carried out at all the designated monitoring stations. The
monitoring frequency shall depend on the scale of the construction activities.
The following is an initial guide on the regular monitoring frequency for each
station on a weekly basis when noise generating activities are underway:
·
One set of measurements between 0700 and 1900 hours
on normal weekdays.
Monitoring
Equipment
3.1.4.
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.
3.1.5.
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.
Air Quality
Monitoring Stations
3.2.1. The air monitoring stations for
the Project are listed and shown in Table 3.2 and Figure 3.1. Appendix 3.1 shows the
established Action/Limit Levels for the monitoring works.

sampling method as set out in the Title 40 of the Code of Federal Regulations,
Chapter 1 (Part 50), Appendix B.
3.2.3. 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.
3.2.4. 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.

monitoring equipment shall be conducted upon installation and thereafter at
bi-monthly intervals. The transfer standard shall be traceable to the
internationally recognized primary standard and be calibrated annually. The
concern parties such as IEC shall properly document the calibration data for
future reference. All the data should be converted into standard temperature
and pressure condition.
Laboratory Measurement /
Analysis
3.2.7. A clean laboratory with constant
temperature and humidity control, and equipped with necessary measuring and
conditioning instruments to handle the dust samples collected, shall be
available for sample analysis, and equipment calibration and maintenance. The
laboratory should be HOKLAS accredited.
3.2.8. Filter paper of size 8” x 10”
shall be labelled before sampling. It shall be a clean filter paper with no
pinholes, and shall be conditioned in a humidity-controlled chamber for over
24-hours and be pre-weighed before use for the sampling.
3.2.9. After sampling, the filter paper

7.0.1.
According
to the Condition 3.4 of the EP-376/2009, 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 Final EM&A report of Central Reclamation Phase III (CRIII) for
Contract HK 12/02, the major construction activities were completed by end of
January 2014 and no construction activities were undertaken thereafter and the
water quality monitoring was completed in October 2011. As such, it is considered that there were no
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) undertaken by
contractor HK12/02 in the reporting period.
7.0.3. According to the construction programme
of Central-Wanchai Bypass at Wanchai West at the Central Reclamation Phase III
area, no works was conducted in July 2020 reporting period. In view of the
above, the cumulative construction impact due to the Central Reclamation Phase
III (CRIII) was not anticipated.
7.0.4.
According to the construction programme of
Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern
Corridor Link projects, no construction works under Wan Chai Development Phase
II was conducted at Wan Chai. The major construction activities under
Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were
ventilation building ABWF works and modification works at Central; drainage
improvement work and utility diversion works at Victoria Park; bridge noise
enclosure installation works, road works, drainage works, soft landscape works
and ventilation building ABWF work at North Point area in the reporting period.
In addition, other non-Wan Chai Development Phase II, Central-Wan Chai Bypass
and Island Eastern Corridor Link projects were observed undertaken at Wan Chai
North and North Point area.
7.0.5.
As
relevant site mitigation measures for air quality and construction noise were
implemented, no significant air quality impact and noise impact from
construction activities was concluded in the reporting period. Besides, no construction
work was conducted at EP-376 area in the reporting period. Thus, it is
evaluated that the cumulative construction impact from the concurrent projects
including Wan Chai Development Phase II (WDII), Central- WanChai Bypass (CWB),
Island Eastern Corridor Link projects (IECL) was insignificant.
8.0.1. The EM&A programme was carried out
in accordance with the EM&A Manual requirements, minor alterations to the
programme proposed were made in response to changing circumstances.
8.0.2. No non-compliance and no prosecutions were received
during the reporting period.
