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
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
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 at 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);
 -
The
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
 -
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 five individual DPs under this Project. Figure 2.1 shows the locations of these Schedule 2 DPs.

Due to the
multi-contract nature of the Project, there are a number of contracts
sub-dividing the whole works area into different work areas to be
commenced. Contractors of individual
contracts will be required by the EP holder to apply Further Environmental
Permits such that the impact monitoring
stations are sub-divided accordingly to facilitate the implementation of
EM&A programme and to streamline the EM&A reporting for individual FEP
holders correspondingly.
2.3.2.
In the reporting period, all the contracts were commenced
and contract no. 04/HY/2006 had been completed. The details of individual
contracts are summarized in Table2.2.

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 agree to within 1.0 dB.
3.1.8.
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.
3.1.9.
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 may be accepted as valid only if the calibration
level from before and after the noise measurement agree to within 1.0 dB.

A water impact complaint was received by ET on 29 August
2011. It was complained by Mr. Au from Cayley Property Management Limited
(CPML) that large amount of rubbishes were found at the harbour front adjacent
to their cooling water intake suction which caused 3 times of system breakdown
of the sea water pump on 9, 22 and 25 August 2011 after the contractors set up
the temporary garbage defender in function and collect the floating refuses,
but cannot eliminate all refuses, in particular the refuse coming from the
seabed. An ad-hoc inspection of the effectiveness of garbage defender was
conducted with RSS (CWB project team), contractors of HY/200911 and HY/2009/19,
ET and IEC on 29 August 2011.
6.0.5.
During on-site inspection, floating refuses were observed
occasionally outside the garbage defender. No conclusion could be made for the
source of these floating refuses. On the other hand, some of the refuses were
observed floating behind the garbage defender during investigation. All daily
cleaning actions had been taken by contractor to minimize floating refuse
inside the construction site. It was noted that the cooling water intake was
accessible to the public. As such, fish breeding and fishing activities were
observed even though a notice has already hoisted. Also, tripping of rubbish by
the passers-by could result in a lot of rubbish accumulated around the intake
point. Referring to the record provided by CPML, there were a lot of nylon/
plastic bags and nylon wire mesh that matched those rubbishes generated from
the public activities. The contractors were reminded to strengthen the
communication with
6.0.6.
To follow up the
ICC complaint no. 1  306740207 regarding the discharged muddy
water from work site to the seafront near Oil Street during heavy rain in August 2011, it was confirmed with RE that muddy
water was caused by a heap of earth being washed to the sea by heavy rain. The
heap of earth was referred as a small stockpile placed close to the seafront in
front of
6.0.7.
Due to the
missing of mitigation measures to protect the small stockpile during handover
transition period, loose material was washed into the harbour when heavy rain came.
Muddy water was formed and dispersed in the sea that caused the water quality
and visual concern to the public. The complaint was considered as valid.
6.0.8.
Contractors were
advised to relocate the loose materials away from the coastline as far as
practicable. Any loose material placed which needed to be placed near the coastline
shall be properly compacted or covered as appropriate. To avoid any further
environmental deficiency, Contractors shall ensure all necessary environmental mitigation
measures will not be missing during site area handover.

complaint was received by Police Officer and a police officer arrived to
Contract HK/2009/01 site at about 6:30 a.m. on 6 November 2011 to inspect noise
generated from the site and stop the existed machines operation. The
subcontractor for Diaphragm wall, SAMBO Korean foreman stopped the engine of
the BC cutter immediately. The police officer recorded the details and HKID
number of the foreman and then left. Due to the different language
communication between the police officer and the Korean foreman, no CNP was
checked by the police officer.
6.0.15. According
to the information reported by Contractor, one BC cutter and a hoist were
operated for inspecting all bentonite pipes were in good condition and all joints
were tightened in good position for Diaphragm Wall construction of
Shatin-Central Link. Due to insufficient communication between Contractor
HK/2009/01 and their Korean Sub-contractor, the Korean Sub-contractor had not
notified to Contractor prior carrying out the inspection of the bentonite pipes
and all pipe joints to ensure no damages and was tightened in good positions at
about 6:00a.m.
6.0.16. As such, the
Contractor HK/2009/01 was reminded to enhance the communication between
Contractor and sub-contractor, and construction Noise Permit should be checked
and in place for the construction works during restricted hour, plus providing
environmental training to all foreman and operators on restricted hour
operation.
