Complaints,
Notifications of Summons and Successful Prosecutions
An ICC complaint (Case Ref:
2-4495970766, lodged at 0955hrs on 12 March 2018) was referred to the ET on 27
March 2018. The ICC hotline operator reported that a public complaint was
referred by the Police Force regarding noise emanation from road construction works
at North Point section Island East Corridor (IEC) near 19 Wharf Road at around 0920hrs
on 12 March 2018. Further information regarding the same event was received via
ICC hotline (Case ref: 2-449606553, lodged at 1004hrs on 12 March 2018) was
referred to the ET on 27 March 2018. The complainant further reported that
noise was emanated from road construction works on Island Eastern Corridor
(IEC) near Yu Lee Mo Fan Memorial School. Temporary noise barrier observed to
be transparent in nature was speculated to be ineffective; and it was observed
that only 3 out of the 6 units of temporary noise barrier are installed. The
complainant suggested that additional 6 sections of noise barrier shall be installed.
The noise emanation was started from 0800hrs and he is a resident at 18 Wharf Road
and his rest was adversely affected by the concerned noise emanation. He has contacted
the Environmental Protection Department and the Police Force regarding the
noise emanation. The Environmental Protection Department has replied that
construction works conducted after 0700hrs does not violate statutory
requirement while the Police Force has created an ICC complaint case file
(2-4495970766) for follow up.
ET confirmed with the Resident Site
Staff that Concrete breaking works on IEC Eastbound near Pier F8 and Pier F9
was conducted under Contract HY/2009/19 from 0900hrs to 1000hrs on 12 March
2018. Noise mitigation measure including wrapping of breaking head with acoustic
material was implemented. Enhancement measures including provision of 2.5m high
temporary noise barrier were subsequent implemented on 12 March 2018.
According to RSS confirmed information,
concrete breaking works on IEC Eastbound near Pier F8 and Pier F9 was conducted
under Contract HY/2009/19 from 0900hrs to 1000hrs on 12 March 2018. Noise
mitigation measure including wrapping of breaking head with acoustic material
was implemented. Enhancement measures including provision of 2.5m high temporary
noise barrier were subsequent implemented on 12 March 2018.
Based on review on relevant site record,
noise impact associated with the breaking works on IECL opposite to the
concerned location was observed across March 2018 and project related exceedances
were recorded at nearby noise monitoring station at YLMF Memorial School across
March 2018. Upon identification of the project related exceedance at YLMF
memorial school noise monitoring station, the Contractor is requested to adopt
remedial and enhancement measures to minimize the noise emanation and avoid
noise impact to the nearby sensitive receivers.
According to ET follow up checking, the
following enhancement measures were proposed and implemented by the Contractor
by 16 March 2018 including provide additional temporary noise barrier and
repair damaged or incomplete temporary noise barrier installed for the breaking
works, provide additional acoustics screen to the breaking tip in addition to temporary
noise barrier installed, provide covering of breaker tip with acoustic material
for noise reduction and conduct breaking works intermittently.
Nevertheless, subsequent to 16 March
2018, it was observed at times that the above mitigation measures were not
fully implemented by the Contractor throughout the remaining breaking works
period. Upon identification of deficiency in mitigation measures, the Contractor
has been requested to rectify any deficiency observed and ensure relevant noise
mitigation measures are implemented and the observed deficiencies are rectified
prior to resumption of the concerned impact associated works. According to
Contractor information, the concerned breaking works have been completed by 26
March 2018.
In view of the public concern and the
identified noise concern, the Contractor of HY/2009/1 was reminded that, shall
future breaking works be required to be conducted on IECL (at works area
located at the East of the noise enclosure), noise mitigation measure including
but not limit to provision of temporary noise barrier with adequate height and
extend and additional noise screen shall be proposed for ET/IEC review and
confirmation prior to conducting the corresponding works to minimize the
potential impact to the surroundings. The Contractor is also advised to review
the adopt construction method with consideration on alterative PME with reduced
noise emanation to minimize the potential noise impact to the surroundings.
An ICC complaint (Case Ref:
2-4530180777) was referred to the ET on 20 April 2018. The complainant reported
that noise pollution was caused by the road works performed by some workers
during midnight at Island Eastern Corridor (near Provident Centre, North Point)
from time to time. They have used heavy noisy machinery and shouted quite often
which disturbed the residents near Provident Centre in North Point seriously.
An EPD complaint case (Case Ref:
H08/RS/00009538-18) was referred to the ET on 23 April 2018. According to EPD
information, the complainant stated that Night time construction noise on
Island Eastern Corridor outside Provident Centre at around 0110hrs on 11th
April 2018.
As the location, time and concern of the
above complaints cased received are identical, the two complaints will be
reported and consolidated into one complaint case for reporting. According to
RSS confirmed information, no construction works was conducted under Contract
HY/2009/19 from 2300hrs on 10 April 2018 to 0100hrs on 11 April 2018.
Installation and welding of steel frames of Traffic Sign FASS06 at works area
opposite to Henrietta Secondary School was conducted under Contract HY/2009/19
between 0100hrs to 0600hrs on 11 April 2018. Total 1 no. of cherry picker, 1
no. of welding machine, 1 no. of lorry, 1 no. of grinder; 3 nos. of with
flashing directional sign and 3 nos. of lorry mounted attenuator were deployed.
Either one PME set consisting 1 no. of welding machine and 1 no. of cherry
picker OR one PME set consisting of 1 no. of lorry and 1 no. of grinder were
operated between 0100hrs to 0600hrs on 11 April 2018 at the concerned works
area. Noise mitigation measures including i) Operation of cherry picker within
permanent noise barrier and ii) Operation of welding machine and grinder inside
acoustic enclosure and iii) Switching off of lorry when idled were implemented
by Contractor of HY/2009/19 for the above construction works. Relevant
Construction Noise Permit numbered GW-RS0249-18 for the above construction works
was in place for the construction works.
In view of the public concern on the
shouting by the workers, the Contractor is also recommended to adopt “walkie-talkie”
for communication to avoid potential nuisance caused to the nearby residents.
The Contractor of HY/2009/19 was reminded to upkeep the site control system for
construction works carried out during restricted hours and night time for Construction
Noise Permit compliance and maintain regular maintenance of the plant and equipment
deployed to avoid potential nuisance to the nearby public.
The First Summons to Defendant was
issued to the Contractors of Contract HY/2009/19 on 18 May 2018 regarding to
carrying out prescribed construction work in Designated Area which was not
permitted in the construction noise permit GW-RS05262-17 and contrary to

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.

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

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.

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.
3.1.4.
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.
3.1.5.

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 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.

One limit level exceedance was recorded at M6
HK Baptist Church Henrietta Secondary School on 06 March 2018 in the March 2018
reporting period.
After checking
with Contractor of HY/2009/19, concurrent saw cutting works and breaking works
was conducted opposite to the monitoring location and the above construction
works were observed as the major noise contribution during monitoring. As such,
the exceedances were considered as Project related. Remedial actions including
saw cutting works alone without concurrent operation of breaker and provision
of additional temporary noise barrier for cutting works were implemented by the
Contractor and no further exceedances was recorded during the additional
monitoring on 08 March 2018. The Contractor of HY/2009/19 was advised to avoid
future concurrent operation of major noise emanating works such as breaking and
saw cutting works to avoid potential cumulative impact.
4.1.9.
One action level exceedance regarding noise
emanation on 12 March 2018 under Contract HY/2009/19 was referred to the
Environmental Team on 27 March 2018 in the March 2018 reporting period.
After investigation, the exceedance was found
to be related to the breaking works conducted on IECL around YLMF memorial
school and Wharf Road causing noise nuisance to the nearby receivers. According
to ET follow up checking, the following enhancement measures were proposed and implemented
by the Contractor by 16 March 2018 including provide additional temporary noise
barrier and repair damaged or incomplete temporary noise barrier installed for
the breaking works, provide additional acoustics screen to the breaking tip in
addition to temporary noise barrier installed, provide covering of breaker tip
with acoustic material for noise reduction and conduct breaking works
intermittently.
