The Proposal for Relocation of Air Quality Monitoring Station at
People’s Liberation Army Headquarter (ACL2) was approved by EPD on 27 November
2013.
4.2.6
According to the approved proposal for relocation of Air Quality
Monitoring station, the action and limit levels of ACL2a shall adopt the
reference monitoring result from the baseline air monitoring report for
EP/364/2009 in 22 April 2010 in which approved by EPD.
4.2.7
The air quality monitoring at ACL2a – Contractor HK/2012/08 Site Office
was commenced on 7 December 2013.
November 2014
4.2.8
No action or limit level exceedance was recorded in the November 2014
reporting period.
December 2014
4.2.9
No action or limit level exceedance was recorded in the December 2014 reporting
period.
January 2015
4.2.10
Action level exceedances were recorded at ACL1 – City Hall and ACL2a – Contractor
HK/2012/08 Site Office on 21 January 2015 during 24hr TSP monitoring in the
January 2015 reporting period.
4.2.11
Although D-wall and
stock H-pile construction were conducted during 24hr TSP monitoring on 21
January 2015, the air pollution level of ambient air quality was considered as
the major contribution to air quality impact. The Air Quality Health Index
(AQHI) recorded by EPD at Central/Western District during the monitoring period
was ranged from 4 to 10+ indicating a severely high concentration of air
pollutants. In addition, similar construction activities and mitigation
measures were undertaken in previous monitoring, no exceedance was
recorded. As such, the implemented
measures were considered effective and exceedance was considered as non-project
related.
4.2.12
The air quality monitoring results measured
in this reporting period are reviewed and summarized. Details of air monitoring results and
graphical presentation can be referred in Appendix 4.2.

4.3.4
One limit level exceedance of suspended
solids was recorded on 10 November 2014 during flood tide in the November 2014 reporting
month. After checking with contractor, no marine works was conducted under
contract HK/2012/08 on the monitoring date, silt curtain installed around
intake monitoring station was generally in order. In view of no marine
activities conducted on the monitoring date and no further exceedance was
recorded in subsequent monitoring, it was considered that the exceedance was
not project related.

7.0.1.
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 – Central – 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 month.
7.0.3.
According to the construction programme of
Wan Chai Development Phase II, Central-Wan Chai Bypass and Island Eastern
Corridor Link projects, the major construction activities under Wan Chai
Development Phase II were marine works at HKCEC areas, tunnel works
and Wan Chai Ferry Pier demolition works at Wan Chai East and filling works at
Wan Chai West. The major construction activities under Central-Wan
Chai Bypass and Island Eastern Corridor Link Projects were bridge construction
and road works at Central Interchange, land base bored pilling works at
Victoria Park Road and ELS works at Victoria Park, segment launching works and
tunnel works at North Point area. Marine-based construction activities were
removal of temporary reclamation at TS4 and EX-PCWA and seawall construction
and filling works at TS3 at Causeway Bay Typhoon Shelter in the reporting
month.
7.0.4.
The major environmental impacts generated
from tunnel works at Central and tunnel works at Wan Chai East, IECL and
Causeway Bay Typhoon Shelter were undertaken in the reporting period. No
significant air impact from construction activities was anticipated in the
reporting period. Besides, no project-related exceedances were recorded during
the water, air and noise environmental monitoring events in the reporting
period. Thus, it is evaluated that the cumulative construction impact from the
concurrent projects including Wan Chai Development Phase II 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-compliances were noted and no
prosecutions were received during the reporting period.
8.0.3. The
construction programmes of individual contracts are provided in Appendix 8.1.
