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:
¡P
A dual 2-lane
primary distributor road, Road P2, approximately 0.6km in length; and
¡P
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:
¡P
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.

Air Monitoring Parameters, Frequency and Duration
3.2.2.
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.
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.

continuously for a 24-hour period.
3.2.6.
Initial calibration of dust 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 loaded with
dust shall be kept in a clean and tightly sealed plastic bag. The filter paper
shall then be 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 shall be regularly calibrated against a

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 ¡V Central ¡V 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 Final EM&A Reports of EP-122/2002/E, EP-356/2009, FEP-01/356/2009,
FEP-02/356/2009, FEP-03/356/2009, FEP-04/356/2009, FEP-05/356/2009,
FEP-06/356/2009, FEP-07/356/2009 and FEP-08/356/2009, the construction works at
these areas of the above EPs and FEPs were completed. In view of the above, the
cumulative construction impact due to the Central Reclamation Phase III (CRIII),
Wan Chai Development Phase II (WDII) and Central-Wan Chai Bypass was not
anticipated.
7.0.4. The major construction activities under
Central-Wan Chai Bypass and Island Eastern Corridor Link Projects were
completed on 31 August 2022
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.
