Complaints, Notifications of
Summons and Successful Prosecutions
ET confirmed with the Resident Site
Staff that bridge works and drains/ sewers construction at the concerned
location was undertaken by Contract HY/2009/18 on 12 November 2015. A stockpile which would be reused for
backfilling was stored at the concerned location by Contract HY/2009/18 on 12
November 2015.
Mitigation measures implemented by the
Contractor for the above construction works including covering of idled portion
of stockpile and dampening of the exposed stockpile was implemented for the
stockpile at the concerned location.
According to relevant site records
confirmed by RSS, bridge works and drains/ sewers construction at the concerned
location was undertaken by Contractor of HY/2009/18 on 12 November 2015 and a
stockpile which would be reused for backfilling was stored at the concerned
location. Mitigation measures including covering of idled portion of stockpile
and dampening of the exposed stockpile was implemented for the stockpile at the
concerned location.
In view of the public concern on
potential dust impact at the concerned location, the Contractor of HY/2009/18
rearranged the works sequence and placed concrete blocks at the bridge
retaining wall to allow for early commencement of backfilling on 19 November
2015 to minimize the size of the stockpile at an earlier stage. Additional
water sprinklers were installed on 27 November 2015 to further enhance the
dampening of the stockpile surface during excavation.
Follow-up inspection was conducted
during weekly environmental inspection on 10 December 2015 and mitigation
measures including covering of stockpile stored at the concerned location was
implemented while it was observed that stockpiles stored near Man Chiu Street
was not properly covered. The Contractor of HY/2009/18 was advised to promptly
provide covering to all idled stockpile stored on site and the Contractor was
reminded to enhance the watering during excavated material handling near the
concerned location. Further follow up inspection was conducted on 17 December
2015 and mitigation measures including covering and watering for idle stockpile
and material handling were implemented.
Over the past couple of weeks, there
have been loud mechanical pounding at the construction site over the reclaimed
area between Blocks 10 and 11 of City Garden. As can be seen, machines have
been breaking open the concrete paved on top of the reclaimed area. Work often
starts well before 9am on weekdays and, barring a brief period of lull during
lunch hours, would often continue unabated until after 5pm. Although I note
that certain noise reduction measures have been put into place (e.g. the
erection of flimsy noise barriers around the work area), the noise created is
still enormous, and this has become a significant nuisance for residents living
in nearby blocks of our estate, especially children and the elderly who have to
stay at home for longer hours.
ET confirmed with the Resident Site
Staff that concreting breaking works was carried out with one breaker on 7, 9,
11, 12 and 14 December 2015 and the breaking works at the concerned location
were completed on 14 December 2015 morning. Noise mitigation measures including
temporary noise barriers near the point of breaking and covering the breaker
with acoustic mat were provided during the concerned concrete breaking works.
According to information confirmed by
RSS, concreting breaking works was carried out by one excavator mounted breaker
on 7, 9, 11, 12 and 14 December 2015 and the concerned breaking works outside
City Garden Block 10 and Block 11 was completed on 14 December 2015 morning.
Noise mitigation measures including temporary noise barriers near the point of
breaking and covering the breaker with acoustic mat were provided during the
concerned concrete breaking works. Based on the further review on the record of
the environmental inspection conducted on 09 December 2015, the Contractor of
HY/2009/19 was reminded to temporary noise barrier provided for the pile cap demolition
shall follow the Environmental Permit EP-364/2009/D requirement.
Follow up inspection was conducted
during weekly environmental inspection on 17 December 2015, the concerned
breaking works opposite to City Garden Block 10 and Block 11 was observed
completed while the Contractor was reminded that the remaining section of
temporary noise barrier in accordance with the latest Environmental Permit
EP-364/2009/D shall be completed on site as soon as possible. According to the
information provided by RSS, the temporary noise barrier in accordance with the
Environmental Permit requirement opposite to City Garden was substantially
completed on 21 December 2015. In view of the public concern, the Contractor
was suggested to consider to review the works duration at daytime and conduct
other future breaking works around the concerned location intermittently to
minimize the potential noise nuisance caused to the surroundings.
Referring to the complaint case regarding
the illegal disposal of construction waste referred by EPD was received by ET
on 17 November 2015, the updated 2nd and 3rd interim investigation report were
submitted to the EPD on 17 December 2015 and 31 December 2015 respectively. In
response to the complaint concern, additional water quality monitoring and
additional site inspections have been conducted by the ET and the investigation
findings were included in the interim investigation reports separately
submitted to the EPD. In addition, the ET and IEC have conducted checking on
the waste disposal records and site construction records with the CWB RSS team
to confirm the key construction activities during the concerned period and the
quantities of inert C&D material disposed. Upon further review on relevant
records and follow up inspections on the implementation of site measures, the
final investigation would be issued.
ET confirmed with the Resident Site
Staff that from 1900hrs to 2115hrs on 06 January 2016, shifting of equipment
and socket H-pile casing was undertaken by the Contractor of HK/2012/08 at the
concerned location. Total one crawler crane was in operation.
According to the relevant site records
provided by RSS, shifting of equipment and socket H-pile casing was undertaken
by the Contractor of HK/2012/08 at the concerned location from 1900hrs to
2115hrs on 06 January 2016. Total one crawler crane was in operation and the
relevant Construction Noise Permit GW-RS0976-15 for the concerned operation was
confirmed in place. Based on the above, the construction activities conducted
under Contract HK/2012/08 on 06 January 2016 after 1900hrs was in compliance
with the statutory requirement. Nevertheless, the Contractor was reminded to
upkeep the site control system for construction works carried out during
restricted hours and night time for Construction Noise Permit compliance in
view of the nearby public concern.
The second ICC complainant on 12 January
2016 (ICC Ref: #2-1759629742) reported that a foul sewer was found choking and
foul water flows onto the carriageways.
ET confirmed with the Resident Site
Staff that no discharge point from the Contractor of HY/2009/15 is located
within the concern portion of public drain (roadside gully) along Hung Hing
Road. The observed yellow pipe extending from the roadside gully at Hung Hing
Road into the site area under Contract HY/2009/15 was installed by the
Contractor of HY/2009/15 to pump excessive sewage from the roadside gully on 11
January 2016.
According to relevant site records and
information provided by RSS, a steady flow of wastewater, noticeably sewer-like
odour, was seeping through an existing sewage manhole at Hung Hing Road on 11
January 2016 and resulting in the formation of local ponding formed around the
low point gully nearby. Based on relevant site information, no discharge point
from the Contractor of HY/2009/15 was located at the concerned public drain
(roadside gully) along Hung Hing Road while the observed yellow pipe extending
from the roadside gully at Hung Hing Road into Contract HY/2009/15 site area
was installed by the Contractor of HY/2009/15 to pump excessive sewage from the
roadside gully on 11 January 2016. In view of no discharge point established
under Contractor HY/2009/15 was observed at the concerned portion of Hung Hing
Road, no direct information indicating the association with the Contractor of
HY/2009/15 is considered available.
Follow up inspection was conducted
during the weekly environmental inspection on 26 January 2016, no further
accumulation of wastewater and no particular blockage of the concerned roadside
gully at Hung Hing Road was observed. In addition, no overflow from the
roadside sewer was observed. Nevertheless, the Contractor of HY/2009/15 was
reminded to upkeep the site exit condition to avoid any potential impact to the
surroundings.

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.

Noise Monitoring
Parameters, Frequency and Duration
3.1.3.
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.
Real
time noise shall be carried out at the designated monitoring stations. The
following is an initial guide on the regular monitoring frequency for each
station on a 24 hours daily basis when noise generating activities are
underway:
·
One
set of measurements between 0700 and 1900 hours on normal weekdays.
·
One
set of measurements between 1900 and 2300 hours on normal weekdays and 0700 and
2300 hours on public holidays.
·
One
set of measurements between 2300 and 0700 hours on next day on everyday.
3.1.6.
If
construction works are extended to include works during the hours of 1900 –
0700 as well as public holidays and Sundays, additional weekly impact
monitoring shall be carried out during respective restricted hours periods.
Applicable permits under NCO shall be obtained by the Contractor.
Monitoring Equipment
3.1.7.
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 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.

6.0.2. First
public complaint regarding construction dust impact referred by EPD was
received by ET on 04 December 2015 (EPD Ref: H04/RS/00028924-15). The
complainant reported that excessive construction dust was generated from the
construction site near Two International Finance Centre at Finance Street,
Central
ET confirmed with the Resident Site
Staff that bridge works and drains/ sewers construction at the concerned
location was undertaken by Contract HY/2009/18 on 12 November 2015. A stockpile which would be reused for
backfilling was stored at the concerned location by Contract HY/2009/18 on 12
November 2015.
Mitigation measures implemented by the
Contractor for the above construction works including covering of idled portion
of stockpile and dampening of the exposed stockpile was implemented for the
stockpile at the concerned location.
According to relevant site records
confirmed by RSS, bridge works and drains/ sewers construction at the concerned
location was undertaken by Contractor of HY/2009/18 on 12 November 2015 and a
stockpile which would be reused for backfilling was stored at the concerned
location. Mitigation measures including covering of idled portion of stockpile
and dampening of the exposed stockpile was implemented for the stockpile at the
concerned location.
In view of the public concern on
potential dust impact at the concerned location, the Contractor of HY/2009/18
rearranged the works sequence and placed concrete blocks at the bridge
retaining wall to allow for early commencement of backfilling on 19 November
2015 to minimize the size of the stockpile at an earlier stage. Additional
water sprinklers were installed on 27 November 2015 to further enhance the
dampening of the stockpile surface during excavation.
Follow-up inspection was conducted
during weekly environmental inspection on 10 December 2015 and mitigation
measures including covering of stockpile stored at the concerned location was
implemented while it was observed that stockpiles stored near Man Chiu Street
was not properly covered. The Contractor of HY/2009/18 was advised to promptly
provide covering to all idled stockpile stored on site and the Contractor was
reminded to enhance the watering during excavated material handling near the
concerned location. Further follow up inspection was conducted on 17 December
2015 and mitigation measures including covering and watering for idle stockpile
and material handling were implemented.
6.0.3. Second
public complaint regarding noise impact referred by RSS was received by ET on
16 December 2015 (ICC Case Ref.: 2-1656689815 dated 14 December 2015). The
complainant reported that incessant noise emanating from the construction site
of the Island Eastern Corridor Link that forms part of the Central-Wanchai
Bypass Project.
Over the past couple of weeks, there
have been loud mechanical pounding at the construction site over the reclaimed
area between Blocks 10 and 11 of City Garden. As can be seen, machines have
been breaking open the concrete paved on top of the reclaimed area. Work often
starts well before 9am on weekdays and, barring a brief period of lull during
lunch hours, would often continue unabated until after 5pm. Although I note
that certain noise reduction measures have been put into place (e.g. the
erection of flimsy noise barriers around the work area), the noise created is
still enormous, and this has become a significant nuisance for residents living
in nearby blocks of our estate, especially children and the elderly who have to
stay at home for longer hours.
ET confirmed with the Resident Site
Staff that concreting breaking works was carried out with one breaker on 7, 9,
11, 12 and 14 December 2015 and the breaking works at the concerned location
were completed on 14 December 2015 morning. Noise mitigation measures including
temporary noise barriers near the point of breaking and covering the breaker
with acoustic mat were provided during the concerned concrete breaking works.
According to information confirmed by RSS,
concreting breaking works was carried out by one excavator mounted breaker on
7, 9, 11, 12 and 14 December 2015 and the concerned breaking works outside City
Garden Block 10 and Block 11 was completed on 14 December 2015 morning. Noise
mitigation measures including temporary noise barriers near the point of
breaking and covering the breaker with acoustic mat were provided during the
concerned concrete breaking works. Based on the further review on the record of
the environmental inspection conducted on 09 December 2015, the Contractor of
HY/2009/19 was reminded to temporary noise barrier provided for the pile cap demolition
shall follow the Environmental Permit EP-364/2009/D requirement.
Follow up inspection was conducted
during weekly environmental inspection on 17 December 2015, the concerned
breaking works opposite to City Garden Block 10 and Block 11 was observed
completed while the Contractor was reminded that the remaining section of
temporary noise barrier in accordance with the latest Environmental Permit
EP-364/2009/D shall be completed on site as soon as possible. According to the
information provided by RSS, the temporary noise barrier in accordance with the
Environmental Permit requirement opposite to City Garden was substantially
completed on 21 December 2015. In view of the public concern, the Contractor
was suggested to consider to review the works duration at daytime and conduct
other future breaking works around the concerned location intermittently to
minimize the potential noise nuisance caused to the surroundings.
Referring to the complaint case regarding
the illegal disposal of construction waste referred by EPD was received by ET
on 17 November 2015, the updated 2nd and 3rd interim investigation report were
submitted to the EPD on 17 December 2015 and 31 December 2015 respectively. In
response to the complaint concern, additional water quality monitoring and
additional site inspections have been conducted by the ET and the investigation
findings were included in the interim investigation reports separately
submitted to the EPD. In addition, the ET and IEC have conducted checking on
the waste disposal records and site construction records with the CWB RSS team
to confirm the key construction activities during the concerned period and the
quantities of inert C&D material disposed. Upon further review on relevant
records and follow up inspections on the implementation of site measures, the
final investigation would be issued.
6.0.4. Third
public complaint regarding construction noise referred by EPD was received by
ET on 14 January 2016 (EPD Ref.: H05/RS/00000570-16 dated 14 January 2016). The
complainant reported that there was operation of powered mechanical equipment
at the construction site near Lung King Street after 1900hrs. (Contract HK/2012/08)
ET confirmed with the Resident Site
Staff that from 1900hrs to 2115hrs on 06 January 2016, shifting of equipment
and socket H-pile casing was undertaken by the Contractor of HK/2012/08 at the
concerned location. Total one crawler crane was in operation.
According to the relevant site records
provided by RSS, shifting of equipment and socket H-pile casing was undertaken
by the Contractor of HK/2012/08 at the concerned location from 1900hrs to
2115hrs on 06 January 2016. Total one crawler crane was in operation and the
relevant Construction Noise Permit GW-RS0976-15 for the concerned operation was
confirmed in place. Based on the above, the construction activities conducted
under Contract HK/2012/08 on 06 January 2016 after 1900hrs was in compliance with
the statutory requirement. Nevertheless, the Contractor was reminded to upkeep
the site control system for construction works carried out during restricted
hours and night time for Construction Noise Permit compliance in view of the
nearby public concern.
6.0.5. Fourth public complaint regarding the subject matter on blocked drainage
were referred by RSS was received by ET on 19 January 2016 (ICC Ref.:
#2-1754682833 and ICC Ref: #2-1759629742). The first ICC complainant (ICC Ref.:
#2-1754682833) on 11 January 2016 reported that the drainage at Hung Hing Road,
Causeway Bay near the entrance of Cross Harbour Tunnel was blocked and sewage
was overflowing from the sewer. The first complainant on 13 January 2016
enquired the status of follow-up, the complainant reported that the sewage
overflow was severe and pose environmental hygiene concern to the surroundings.
The first complainant on 14 January 2016 reported that the situation was not
improved and would escalate the case if not addressed.
The second ICC complainant on 12 January
2016 (ICC Ref: #2-1759629742) reported that a foul sewer was found choking and
foul water flows onto the carriageways.
ET confirmed with the Resident Site
Staff that no discharge point from the Contractor of HY/2009/15 is located within
the concern portion of public drain (roadside gully) along Hung Hing Road. The
observed yellow pipe extending from the roadside gully at Hung Hing Road into
the site area under Contract HY/2009/15 was installed by the Contractor of
HY/2009/15 to pump excessive sewage from the roadside gully on 11 January 2016.
According to relevant site records and
information provided by RSS, a steady flow of wastewater, noticeably sewer-like
odour, was seeping through an existing sewage manhole at Hung Hing Road on 11
January 2016 and resulting in the formation of local ponding formed around the
low point gully nearby. Based on relevant site information, no discharge point
from the Contractor of HY/2009/15 was located at the concerned public drain
(roadside gully) along Hung Hing Road while the observed yellow pipe extending
from the roadside gully at Hung Hing Road into Contract HY/2009/15 site area
was installed by the Contractor of HY/2009/15 to pump excessive sewage from the
roadside gully on 11 January 2016. In view of no discharge point established
under Contractor HY/2009/15 was observed at the concerned portion of Hung Hing
Road, no direct information indicating the association with the Contractor of
HY/2009/15 is considered available.
Follow up inspection was conducted
during the weekly environmental inspection on 26 January 2016, no further
accumulation of wastewater and no particular blockage of the concerned roadside
gully at Hung Hing Road was observed. In addition, no overflow from the
roadside sewer was observed. Nevertheless, the Contractor of HY/2009/15 was
reminded to upkeep the site exit condition to avoid any potential impact to the
surroundings.
6.0.6. Fifth public complaint regarding the blockage of public drainage
referred by EPD was received by ET on 22 January 2016 (EPD Case Ref.:
H05/RS/00001524-16). The complainant reported that construction wastewater from
the China State’s construction site under Contract HY/2009/15 was discharged

complainant reported that excessive construction dust was generated from the
construction site near Two International Finance Centre at Finance Street, Central
ET confirmed with the Resident Site
Staff that bridge works and drains/ sewers construction at the concerned
location was undertaken by Contract HY/2009/18 on 12 November 2015. A stockpile which would be reused for backfilling
was stored at the concerned location by Contract HY/2009/18 on 12 November
2015.
Mitigation measures implemented by the
Contractor for the above construction works including covering of idled portion
of stockpile and dampening of the exposed stockpile was implemented for the stockpile
at the concerned location.
According to relevant site records
confirmed by RSS, bridge works and drains/ sewers construction at the concerned
location was undertaken by Contractor of HY/2009/18 on 12 November 2015 and a
stockpile which would be reused for backfilling was stored at the concerned
location. Mitigation measures including covering of idled portion of stockpile
and dampening of the exposed stockpile was implemented for the stockpile at the
concerned location.
In view of the public concern on
potential dust impact at the concerned location, the Contractor of HY/2009/18
rearranged the works sequence and placed concrete blocks at the bridge
retaining wall to allow for early commencement of backfilling on 19 November
2015 to minimize the size of the stockpile at an earlier stage. Additional
water sprinklers were installed on 27 November 2015 to further enhance the
dampening of the stockpile surface during excavation.
Follow-up inspection was conducted during weekly environmental inspection
on 10 December 2015 and mitigation measures including covering of stockpile
stored at the concerned location was implemented while it was observed that
stockpiles stored near Man Chiu Street was not properly covered. The Contractor
of HY/2009/18 was advised to promptly provide covering to all idled stockpile
stored on site and the Contractor was reminded to enhance the watering during
excavated material handling near the concerned location. Further follow up
inspection was conducted on 17 December 2015 and mitigation measures including
covering and watering for idle stockpile and material handling were
implemented.
8.0.21. Second public complaint regarding noise impact referred by RSS was
received by ET on 16 December 2015 (ICC Case Ref.: 2-1656689815 dated 14 December
2015). The complainant reported that incessant noise emanating from the
construction site of the Island Eastern Corridor Link that forms part of the
Central-Wanchai Bypass Project.
Over the past couple of weeks, there
have been loud mechanical pounding at the construction site over the reclaimed
area between Blocks 10 and 11 of City Garden. As can be seen, machines have
been breaking open the concrete paved on top of the reclaimed area. Work often
starts well before 9am on weekdays and, barring a brief period of lull during
lunch hours, would often continue unabated until after 5pm. Although I note
that certain noise reduction measures have been put into place (e.g. the
erection of flimsy noise barriers around the work area), the noise created is still
enormous, and this has become a significant nuisance for residents living in
nearby blocks of our estate, especially children and the elderly who have to
stay at home for longer hours.
ET confirmed with the Resident Site
Staff that concreting breaking works was carried out with one breaker on 7, 9,
11, 12 and 14 December 2015 and the breaking works at the concerned location

information provided by RSS, the temporary noise barrier in accordance with the
Environmental Permit requirement opposite to City Garden was substantially
completed on 21 December 2015. In view of the public concern, the Contractor
was suggested to consider to review the works duration at daytime and conduct
other future breaking works around the concerned location intermittently to
minimize the potential noise nuisance caused to the surroundings.
