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 second 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 November 2003 to 31 January 2004.
Environmental Monitoring and Audit Progress
Noise and water
quality monitoring was conducted during this quarter.
Weekly environmental site inspections were also conducted during the reporting
quarter. Joint site inspections were also
carried out on 13 November, 10 December 2003 and 14 January 2004. The IEC's environmental site inspection
reports are included in Annex H.
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
January 2004, 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 previously noted that City Hall is affected by various
noise sources unrelated to the project.
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 suspended solids
(SS) levels 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, dredging works at IRAW and IRAE
and preparation for demolition of the General Post Office (GPO) Walkway.
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 and IRAE;
·
Marine and land-based site investigation works;
·
Maintenance and necessary repair work for seawater
intake silt screens;
·
Preparation for demolition work of the General Post
Office (GPO).
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 are proceeding.
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.

There were no notifications of summons and

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, minor deficiencies were noted. However, the Contractor rectified all deficiencies after receipt
of notification.
