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 2.1.
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.
2.2.1.
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.

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.
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.
Sampling Procedure and Monitoring Equipment
3.2.5.

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

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, construction of ELS and
pipe pile wall, road works and drainage were performed in July 2015 reporting
month. As no
project related exceedance were recorded during the reporting period,
cumulative construction impact due to the concurrent activities of the current
projects with the Central Reclamation Phase III (CRIII) was considered as
insignificant.
7.0.4.
According to the construction programme of Wan Chai Development Phase
II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, the
major construction activities under Wan Chai Development Phase II were
tunnel works, ELS works and culvert construction at Wan Chai East and removal
of L-shape wall, D-wall construction and ELS works at Wan Chai West. The
major construction activities under Central-Wan Chai Bypass and Island Eastern
Corridor Link Projects were bridge construction and road works at Central
Interchange, ELS works at Ex-PCWAW, ELS works and bowling green office
demolition at Victoria Park, D- wall construction and ELS works at TS3, IEC
demolition and tunnel works at North Point area in the reporting period.
7.0.5.
No significant air quality impact from
construction activities was anticipated in the reporting period. Besides, no
project related exceedance was recorded during air quality and noise environmental
monitoring events in the reporting period. Thus, it is evaluated that the
cumulative construction impact from the concurrent projects including Central
Reclamation Phase III (CRIII), 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.
8.0.3. Mitigation measures according to the environmental mitigation
implementation schedule and the EIA were generally implemented by the
Contractor in this reporting period. Environmental site audit was conducted by
the Environmental Team and the Independent Environmental Checker and no
cumulative environmental impact was identified in the reporting period. Hence,
the EM&A programme was considered effective and shall be maintained.
8.0.4. The
construction programmes of individual contracts are provided in Appendix 8.1.
