FEP-03/356/2009 to implement the Environmental Monitoring and Audit (EM&A)
programme as stipulated in the EM&A Manual of the approved Environmental
Impact Assessment (EIA) Report for Wan Chai Development phase II and
Central-Wan Chai Bypass (Register No.: AEIAR-125/2008) and in the EM&A
Manual of the approved EIA Report for Central-Wan Chai Bypass and Island
Eastern Corridor Link (Register No. AEIAR-014/2001).

Section 8 Conclusion
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 Island Eastern Corridor Link (Register
No. AEIAR-041/2001) and Wan Chai Development phase II and Central-Wan Chai
Bypass (Register No.: AEIAR-125/2008) have been approved on 31 August 2001 and
11 December 2008 respectively.
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 east-west Connaught Road Central/Harcourt
Road / Gloucester Road Corridor (the Corridor) which is currently operating
beyond its capacity. The CWB will provide relief to the existing congestion
along the Corridor and cater for the anticipated growth of traffic on Hong Kong
Island. Without the CWB and its access roads, there will not be sufficient
capacity to serve the heavy traffic demands at both strategic and local levels.
2.2.1.
The Project is located mainly in Wan Chai North,
Causeway Bay and North Point, and is demarcated by Gloucester Road and Victoria
Park Road to the south, Fenwick Pier Street to the west and Tong Shui Road
Interchange to the east, as shown in Figure 2.1.
2.2.2.
The study area encompasses existing developments
along the Wan Chai, Causeway Bay and North Point shorelines. Major land uses
include the Hong Kong Convention & Exhibition Centre (HKCEC) Extension, the
Wan Chai Ferry Pier, the ex-Wan Chai Public Cargo Working Area (ex-PCWA), the
Royal Hong Kong Yacht Club (RHKYC), the Police Officers' Club, the Causeway Bay
Typhoon Shelter (CBTS) and commercial and residential developments.
2.2.3.
The
scope of the Project comprises:
-
Land formation for key
transport infrastructure and facilities, including the Trunk Road (i.e.
CWB) and the associated slip roads for connection to the Trunk Road and for through
traffic from Central to Wan Chai and Causeway Bay. The land formed for the above
transport infrastructure will provide opportunities for the development of an
attractive waterfront promenade for the enjoyment of the public
-
Reprovisioning /
protection of the existing facilities and structures affected by the land
formation works mentioned above
-
Extension, modification,
reprovisioning or protection of existing storm water drainage outfalls,
sewerage outfalls and watermains affected by the revised land use and land
formation works mentioned above
-
Upgrading of hinterland
storm water drainage system and sewerage system, which would be rendered
insufficient by the land formation works mentioned above
-
Provision of the ground
level roads, flyovers, footbridges, necessary transport facilities and the
associated utility services
-
Construction of the new
waterfront promenade, landscape works and the associated utility services
-
The
Trunk Road (i.e. CWB) within the study area and the associated slip roads for
connection to the Trunk Road.
2.2.4.
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 (FEP) 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
3.1.2.
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:
-
one set of measurements between 0700 and 1900
hours on normal weekdays.
3.1.4.
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.
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.
3.3.1.
The EIA Report has identified that the key
water quality impact would be associated with the dredging works during the
construction phase. Marine water
quality monitoring for dissolved oxygen (DO), suspended solid (SS) and
turbidity is therefore recommended to be carried out at selected WSD flushing
water intakes. The impact monitoring
should be carried out during the proposed dredging works to ensure the
compliance with the water quality standards.
Water Quality Monitoring Stations
3.3.2.
It is proposed to monitor the water quality
at 9 WSD salt water intakes and 14 cooling water intakes along the seafront of
the Victoria Harbour. The proposed water quality monitoring stations of the
Project are shown in Table 3.3 and Figure 3.1. Appendix 3.1 shows the established
Action/Limit Levels for the monitoring works.

Water Quality Parameters and frequency
3.3.3.
Monitoring of dissolved oxygen (DO),
turbidity and suspended solids (SS) shall be carried out at WSD flushing water
intakes and cooling water intakes. DO and Turbidity are measured in-situ while
SS is determined in laboratory.
3.3.4.
In association with the water quality
parameters, other relevant data shall also be measured, such as monitoring
location/position, time, sampling depth, water temperature, pH, salinity,
dissolved oxygen (DO) saturation, weather conditions, sea conditions, tidal
stage, and any special phenomena and work underway at the construction site
etc.
3.3.5.
The interval between two sets of monitoring
should not be less than 36 hours except where there are exceedances of Action
and/or Limit Levels, in which case the monitoring frequency will be
increased. Table 3.4 shows the
proposed monitoring frequency and water quality parameters. Duplicate in-situ measurements and water
sampling should be carried out in each sampling event. For selection of tides for in-situ
measurement and water sampling, tidal range of individual flood and ebb tides
should be not less than 0.5m.

4.1.2.
Reviewed the past monitoring results and
observation at Station M4a, the monitoring location at Causeway Bay Community
Centre is facing and closed to the Island Eastern Corridor. Traffic noise is
the major noise source obtained in the monitoring that cannot reflect the
construction noise from the construction site. Victoria Centre (Station ID:
M4b) was proposed as alternative noise monitoring station effective from August
2010.
4.1.3.
Two action level exceedances
were recorded due to the noise complaints on 31 July and 12 August 2010. There
were complained on the construction noise nuisance from the dredging work
activities at North Point District. Contractor’s site practical and measurement
results were reviewed. The details of the complaints can be referred to Section
6 and Appendix 6.1.
4.1.4.
Five limit level
exceedances were recorded at M4a on 8 and 22 June 2010 and 20 and 27 July 2010
and at M5b on 16 June 2010 August 2010. All exceedances were investigated and
found not attributed to the project works as major
noise source was obtained from the Island Eastern Corridor. It was
concluded that the exceedances were not due to the project.

4.4.6.
There was marine sediment (Type 1 Open Sea Disposal (Dedicate Sites) &
Type 2 Confined Marine Disposal) disposed in reporting
quarter at a maximum dredging rate 1,590m3 per day. On-going ET site
inspections observed that the temporary western seawall has been partially
constructed since early August 2010 with no apparent water quality impact
reported for the stations WSD21, C5e and C5w, it is considered the maximum
dredging rate at WCR can be stepped up to 6,000m3 as per the
criteria under Table 5.10 of EIA Report Register No. AEIAR-125/2008 for
dredging with WCR area.
5.0.1.
The Event Action Plan for construction noise,
air quality and water quality are presented in Appendix 5.1.
5.1.1.
Two action level exceedances
were recorded due to the noise complaints on 31 July and 12 August 2010. There
were complained on the construction noise nuisance from the dredging work
activities at North Point District. Contractor’s site practical and noise
monitoring results were reviewed. Investigation found that the complaints were
considered not valid from the Environmental Permit and Construction Noise
Permit point of view. The details of the complaints can be referred to Section
6 and Appendix 5.1.
5.1.2.
Eleven limit level
exceedances were recorded in the reporting quarter. All exceedances
were investigated and found not attributed to the project works as major noise source was obtained from the traffic
noise. Besides, crowd noise from the Wan Chai Training Pool was also
contributed during evening noise monitoring at M1a Harbour Road Sports Centre. It was concluded that the exceedances were not due
to the project.
5.2.1.
One action level exceedance was recorded at
CMA1b on 24 August 2010. Investigation found that the exceedance was due to the
burning joss paper activities near CMA1b.
5.3.1.
The summary of water quality exceedances
recorded in reporting quarter is presented in the Table 5.1.

5.3.2.
Since all exceedances recorded were not
project-related, follow-up mitigation measures were therefore not required.
5.4.1
Existing Action and
Limit Levels were derived based on the 4-weeks baseline water quality monitoring
data obtained during the dry season in October and November 2009 prior to the
commencement of construction. The Action
and Limit Levels are applied the water monitoring for all seasons.
5.4.2
Owing to the frequent
non-project related exceedances caused by fluctuation in coastal water quality
due to localized effect, it is considered the existing Action and Limit Levels
values were underestimated to the natural variation of water quality around the
baseline range. It is recommended to
review the existing Action and Limit Levels on water quality in order to take
into the account of the coastal activities and potential variation of coastal
water qualities during wet season (i.e. Apr Sep period). Action and Limit
levels for wet season were devised based on a projected scenario calculated
using the marine water quality data obtained at the closest EPD routine
monitoring stations as per EM&A Manual Section 4.10.4 which states,
“Where necessary, EPD routine water quality monitoring data at the relevant station(s), dry and wet seasons inclusive, could also be used to established the baseline water quality. o:p>
5.4.3
While the existing
Action and Limit levels will continue to be used for impact monitoring for dry
season (Oct Mar period), an additional set of Action and Limit levels are
proposed for use in the coming wet season and are summarized in Table
5.2. The details of calculation
using the marine water quality data obtained at the closest EPD routine
monitoring stations can be referred to Appendix 5.2.

7.0.1.
According to Condition 3.4 of the EP-356/2009, this
section addresses the relevant cumulative construction impact due to the
concurrent activities of the current projects including the Central Reclamation,
Central-WanChai Bypass and Island Eastern Corridor Link projects.
7.0.2.
According to the construction programme of Central-Wan
Chai Bypass and Island Eastern Corridor Link projects, the major construction activity
under Wan Chai Development Phase II was the dredging works at North Point Reclamation
Stage 1(NPR1), Wan Chai Reclamation Stage 1(WCR1) and Cross Harbour Water Mains
in the reporting quater. The major environmental impact was water quality
impact at North Point and Wan Chai. No major construction activities were
undertaken in the Central-Wan Chai Bypass and Island Eastern Corridor Link
projects.
7.0.3.
The major environmental impacts generated from
the Central Reclamation Phase III were located along the coastline of Central
and Admiralty while dredging works at NPR1, WCR1 and Cross Harbour Water Mains were
in operation in this reporting quarter. The dredging works was just commenced
at WCR1 and Cross Harbour Water Mains in this reporting quarter. /span>Beside, water quality mitigation measures
were properly in place for the dredging works in this reporting quarter. No
project related exceedance was recorded. Thus, it is evaluated that the cumulative
construction impact from the concurrent projects including Wan Chai Development
Phase II and Central Reclamation Phase III 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 project-related exceedance,
non-compliances were noted and no prosecutions were received during the
reporting quarter.
8.0.3.
Owing to the frequent non-project related
exceedances caused by fluctuation in coastal water quality due to localized
effect, it is considered the existing Action and Limit Levels values were
underestimated to the natural variation of water quality around the baseline
range. It is recommended to review
the existing Action and Limit Levels on water quality in order to take into the
account of the coastal activities and potential variation of coastal water
qualities during wet season (i.e. Apr Sep period). While the existing Action and Limit levels will continue to be used for impact monitoring for
dry season (Oct Mar period), an additional set of Action and Limit
levels are proposed for use in the coming wet season.
8.0.4.
The construction programmes of individual contracts
are provided in Appendix 8.1.
