Executive Summary
Atkins China Limited (ACL) has been appointed by TDD to implement the
Environmental Monitoring and Audit (EM&A) programme that was identified in
the EIA Report for the CRIII Project and is providing Environmental Team
services during the duration of the construction works.
This is the first quarterly
EM&A - TDD Progress Report for the
works specified in Section 1.3 of the CRIII EIA Report. This report summarises the monitoring
results and audit findings of the EM&A program during the reporting period
from 1 August to 31 October 2003.
Environmental Monitoring and Audit Progress
Noise and water quality monitoring was conducted during this quarter.
Exceedances of Action and Limit Levels
The noise monitoring carried out during this quarter did not find any
exceedances that were attributable to the project works. Although the continuous monitoring data
indicated several instances where the Leq (30 minutes) exceeded 75 dB(A) during
October 2003, investigations into these levels found that they were due to
local noise conditions at the City Hall monitoring location and were not due to
the project. An off-site inspection
carried out by the IEC on 21 October 2003 confirmed these findings. The IEC's observations noted that the main
sources of noise near City Hall were from helicopter and vehicle traffic in the
area.
From the analysis of water quality monitoring results collected during
this quarter, no exceedances were found to be attributable to the project
marine works. Although the monitoring
data indicated that levels of dissolved oxygen (DO) and suspended solids (SS)
beyond the water quality criteria were found, investigations into these exceedances
determined that they were due to natural variation in ambient conditions and/or
local influencing factors in proximity of the affected monitoring stations, and
they were not due to the project. The
investigations considered the conditions from baseline monitoring, which was
conducted during February to April 2003, and results from the control stations
located outside the project's influence.
A review of the monitoring results showed that control stations located
outside the project's influence had similar values as marine impact stations. Seawater intake monitoring data showed
variable results and exceedances were found to be localised near existing
stormwater outfalls. These findings
were similar to the conditions observed during baseline monitoring. Further, silty discharges from outfalls
within the project area have been documented on various occasions. Based on the investigations and analyses of
the water quality data, it was confirmed that the project marine works did not
cause any of the exceedances of the water quality criteria.
Complaint Log
There were no environmental complaints
received during the reporting period.
Notifications of Summons and Prosecutions
There were no notifications of summons or
prosecutions received during this reporting quarter.
Site Inspection and
Audit
Weekly
environmental site inspections were carried out during this quarter. Several minor deficiencies were noted during
the site inspections but the Contractor rectified all deficiencies upon receipt
of notification.
The Territory Development Department (TDD) of the
Hong Kong Special Administrative Region (HKSAR) is constructing the Central
Reclamation Phase III project (CRIII).
The Main Works Contract HK 12/02 for CRIII
commenced on 28th February 2003. Leighton China State Van Oord Joint
Venture (LCSVO-JV) was awarded the Contract No. HK 12/02 for the construction
of the CRIII Engineering Works. The
main construction works that were identified in the EIA Report for the Project,
requiring environmental monitoring and audit, have not yet commenced. The Contractor is presently preparing for
commencement of land and marine based construction works. Activities under this contract to date include
marine and land-based site investigations, demolition at Pier No.7 and dredging
works at IRAW.
The Contractor's works programme for the quarter is
provided in Annex E.
Atkins China Limited (ACL) has been
commissioned by TDD, the employer, to undertake the environmental monitoring and
audit work for the project. ACL is also
the Resident Engineers for the project and LCSVO-JV is the main
contractor. An Independent
Environmental Checker (IEC) has been employed to audit the EM&A
programme. The contacts of key
management are provided in Annex A.
The works undertaken in the project area
requiring environmental monitoring and audit as identified in the EIA Report
(not including Chai Wan Basin) during the quarter included:
·
Demolition work at Pier No.
7;
·
Dredging and reclamation
works at IRAW;
·
Marine pile splicing and
welding of pile shoes;
·
Marine site investigation
works at the Eastern Seawall;
·
Site investigation works for
the Man Yiu Street Footbridge; and
·
Temporary traffic and
pedestrian diversion arrangements near Pier No. 7.
A suspension of all construction works took
place between 28 September and 8 October 2003.
All marine piling works and any reclamation above the original seabed
level are still being suspended until further notice while other marine works
and land-based activities have resumed.
The EM&A programme requires environmental monitoring for air
quality, noise, water quality, waste management and landscape and visual
aspects as specified in the CRIII Project EIA.
The EM&A requirements for each issue area are described in
subsequent sections including:
·
All required monitoring parameters;
·
Action and Limit Levels; and
·
Event-Action Plans.
A summary of impact EM&A requirements is presented in Table
2-1.

Environmental Quality Performance Limits for dust, noise and water
quality have been established as part of the Baseline Monitoring Report and are
provided in Annex B.
Event Action Plans for air, noise and water quality have been developed
as part of the Baseline Monitoring Report and are provided in Annex
C.
The Contractor has implemented relevant mitigation measures listed in
the EIA Report, EM&A Manual and Further Environmental Permit. Seawater intake silt screens have been
installed prior to the start of the dredging works and a silt curtain attached
to a floating steel frame has been installed around the grab dredger.
Drawings showing the project area and locations of the monitoring
stations are provided in Annex D.
Once dust generating construction works have commenced, results of air
quality monitoring will be presented with graphical plots to depict trends over
a 4-month period (including the last month of the previous quarter and the
present quarter).
The graphical plot of noise quality monitoring results for this quarter
is provided in Annex F.
The graphical plot of water quality monitoring results for this quarter is provided in Annex G. An analysis of the monitoring results did not find any construction impacts on suspended solids (SS) at the project site. Although elevated levels of SS were found, particularly at the seawater intake stations (M1 to M6 and M11 and M12), these were investigated and were found to be not due to project works. The elevated SS levels were generally localised and occurred at seawater intake stations located near outfalls. Silty discharges from outfalls that are unrelated to the project works have been observed and documented in the reporting period. These discharges have been reported to the Environmental Protection Department (EPD) and are currently being investigated.
Solid and liquid waste management was implemented according to the Waste
Management Plan during the reporting quarter.
As the works undertaken during the reporting
month were related to site investigation works, minor demolition works and
dredging works, the landscape and visual impacts are considered to be minimal.
There were no exceedances of air, noise and
water quality due to the project works found during the reporting quarter.
As there were no instances of non-compliance
due to the project works in this reporting quarter, no actions and follow-up
procedures were required.
No environmental complaints were received
during the reporting quarter. Further,
no environmental prosecution notices or summons were received during the
reporting quarter.
The following table summarises all the
complaints received (both written and verbal) and the liaison/consultation
undertaken, and the actions and follow-up procedures taken.

During the reporting
quarter, no exceedances of environmental performance criteria were found to be
caused by the project works. For water
quality monitoring, low DO levels and elevated SS concentrations recorded were
investigated and have been attributed to either ambient conditions or adverse
influencing factors unrelated to project marine works. It was found that discharges from outfalls
located near seawater intake monitoring stations are major influencing factors
that adversely impact water quality within the works site area.
The marine-based impact
monitoring stations established to monitor the overall impact of the
reclamation activities on water quality in Victoria were shown to have similar
results as the control stations which are located outside the influence of
project works. As such, the water
quality monitoring results did not indicate that the marine works were
adversely affecting water quality outside the works boundary in Victoria
Harbour.
During environmental site
inspections conducted during the reporting quarter, several minor deficiencies
were noted. However, the Contractor
rectified all deficiencies after receipt of notification.
