Section 7 Conclusion
2.1.1.
“Wan Chai Development phase II and Central-Wan Chai Bypass” and
“Central-Wan Chai Bypass and Island Eastern Corridor Link” (hereafter called
“the Project”) are Designed Project (DP) under the Environmental Impact
Assessment Ordinance (Cap. 499) (EIAO). The Environmental Impact Assessment
(EIA) Reports for Central-Wan Chai Bypass and Island Eastern Corridor Link (Register
No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai
Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and
11 December 2008 respectively.
2.1.2.
The key purpose of Wan Chai Development Phase II (WDII) is to provide
land at Wan Chai North and North Point for construction of the Central-Wan Chai
Bypass and Island Eastern Corridor Link (CWB). Land formed under the project
will be developed as a world-class waterfront promenade joining that at the new
Central waterfront for public enjoyment.
2.1.3.
There is a compelling and present need for the CWB to provide relief to
the very congested east-west Connaught Road Central / Harcourt Road /
Gloucester Road Corridor (the Corridor) which is currently operating beyond its
capacity. The CWB will provide relief to the existing congestion along the
Corridor and cater for the anticipated growth of traffic on Hong Kong Island.
Without the CWB and its access roads, there will not be sufficient capacity to
serve the heavy traffic demands at both strategic and local levels.
2.2.1.
Design and Construction of Central – Wan Chai Bypass and Island Eastern
Corridor Link under the Project involves the construction and operation of a
trunk road and its road tunnel more than 800m in length between portals that is
shown in Figure 2.1.
2.2.2.
The study area encompasses existing developments from Central to North
Point. The scope of the Central-Wanchai Bypass (CWB) and Island Eastern
Corridor Link (IECL) includes:
·
A dual three-lane trunk road,
approximately 4.5 km in length, and tunnel approximately 3.7 km in length defined
from the connection with the existing Rumsey
·
Street Flyover in Central, through
to a connection with the existing Island Eastern
·
Corridor to the east of the
Causeway Bay Typhoon Shelter (CBTS);
·
Central Interchange near the
Rumsey Street Flyover to provide road connections
·
to the Central area;
·
Tunnel control buildings and
ventilation buildings;
·
Slip roads to connect the CWB to
the local road system in the Wan Chai North and
·
Causeway Bay area;
·
Associated road lighting, road
signing, traffic control and surveillance system; and
·
Other associated works.
2.2.3.
The project also contains various Schedule 2 DPs 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 three
individual DPs under this Project. Figure 2.1 shows the locations
of these Schedule 2 DPs.

Noise Monitoring Parameters, Frequency and Duration
3.1.3.
The construction noise level was
measured in terms of the A-weighted equivalent continuous sound pressure level
(Leq). Leq (30 minutes) was 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) was employed for
comparison with the Noise Control Ordinance (NCO) criteria. Supplementary information for
data auditing, statistical results such as L10 and L90 were also obtained for
reference.
3.1.4.
Noise monitoring was carried out at all the designated monitoring
stations. The monitoring frequency depended 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
were underway:
·
One
set of measurements between 0700 and 1900 hours on normal weekdays.
3.1.5.
If construction works were extended to include works during the hours of
1900 – 0700 as well as public holidays and Sundays, additional weekly impact
monitoring was carried out during respective restricted hour’s periods.
Monitoring Equipment
3.1.6.
As referred to 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 were used
for carrying out the noise monitoring. Immediately prior to and following each
noise measurement the accuracy of the sound level meter was checked using an
acoustic calibrator generating a known sound pressure level at a known
frequency. Measurements were accepted as valid only if the calibration level
from before and after the noise measurement agree to within 1.0 dB.
3.1.7.
Noise measurements was not carried out in fog, rain, wind with a steady
speed exceeding 5 m/s or wind with gusts exceeding 10 m/s. The wind speed was
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 in Table 3.2 and shown in Figure 3.1. Corresponding air
sensitive receivers as identified in EIA can be referred to Appendix 3.0. Appendix

Air Monitoring Parameters, Frequency and Duration
3.2.2.
One-hour and 24-hour TSP levels were measured to indicate the impacts of
construction dust on air quality. The 24-hour TSP level was 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., were recorded down in
detail.
3.2.4.
For regular impact monitoring, the sampling frequency of at least once
in every six-days, was 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 was undertaken when the highest dust impact
occurred.
Sampling Procedure and Monitoring Equipment
3.2.5.
High volume samplers (HVSs) in compliance with the following
specifications were used for carrying out the 1-hour and 24-hour TSP
monitoring:

3.2.6.
Initial calibration of dust monitoring equipment was conducted upon
installation and thereafter at bi-monthly intervals. The transfer standard was
traceable to the internationally recognized primary standard and be calibrated
annually. The concern parties such as IEC was properly document the calibration
data for future reference. All the data was 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, was available for sample analysis, and equipment
calibration and maintenance. The laboratory was HOKLAS accredited.
3.2.8.
An alternative non-HOKLAS accredited
laboratory was set-up for carrying out the laboratory analysis,
the laboratory equipment was approved by the ER on
8 February 2011 and the
measurement procedures were witnessed by the IEC. Any measurement
performed by the laboratory was demonstrated to the satisfaction of the
ER and IEC. IEC was regularly audit to the measurement performed by the
laboratory to ensure the accuracy of measurement results.
3.2.9.
Filter paper of size 8” x 10” was labelled before sampling. It was a
clean filter paper with no pinholes, and conditioned in a humidity-controlled
chamber for over 24-hours and pre-weighed before used for the sampling.
3.2.10.
After sampling, the filter paper loaded with dust was kept in a clean
and tightly sealed plastic bag. The filter paper was then returned to the
laboratory for reconditioning in the humidity controlled chamber followed by
accurate weighing by an electronic balance with readout down to 0.1 mg. The
balance was regularly calibrated against a traceable standard.
3.2.11.
All the collected samples were kept in a good condition for 6 months
before disposal.

Validity
of EIA Predictions
7.2.1
It is predicted in the
EIA reports that with the implementation of the recommended mitigation
measures, there would be no unacceptable or residual air, water quality and
noise impacts arising from the Project-related construction works.
Comments
on Overall EM&A programme
7.2.2
The mitigation
measures detailed in the Environmental Permit, the EM&A Manual and the EIA
report were implemented throughout the whole project period. With the
environmental monitoring and site inspection to directly ensure the timely
implementation of mitigation measures during the Project, the environmental
performance of the Project was acceptable. Analysis of all EM&A data
collected throughout the construction periods also demonstrated the
environmental acceptability of the Project.
7.2.3
The overall
performance of the monitoring methodology adopted and environmental management
system in this Project was effective.
Overall
EM&A Data
7.2.4
Baseline and impact
air and noise monitoring were carried out according to the requirements in the
EM&A Manual. The monitoring data analysis shown that the environmental
conditions generally return to baseline condition.
Conclusions
7.2.5
The EM&A programme
was found to be effective in monitoring impacts arising from the Project. The
findings of the environmental monitoring programme suggest that no adverse
impacts on sensitive receivers were brought about by the Project. In conclusion
the Project was environmentally acceptable in terms of air quality, noise,
water discharge and waste disposal.
7.2.6
With the success of
the overall EM&A programme, the deterioration of the environment caused by
the Project was cost-effectively identified and necessary prompt effective
mitigation measures were implemented to avoid any unacceptable impacts.
