1.0 BASIC PROJECT INFORMATION
1.1 Background
Downer Construction (Hong Kong) Limited is the Contractor for the
Supplementary Agreement No. 3 (SA3) for the Contract No. HY/98/22 Road Widening
Works of Salisbury Road between Nathan Road and Canton Road. The major
activities during construction of SA3 includes widening of the existing
carriageways by providing an additional lane from Hong Kong Space Museum to
Hong Kong Cultural Centre. Other construction works include resurfacing,
central divider and footpath reconstruction, drainage works and landscaping
works.
The purpose of this report is to report the EM&A works in the period

2.0 SUMMARY OF EM&A REQUIREMENTS
2.1 Air Quality
According to
Section 1.3 of the EM&A Manual, the captioned project involves minor road
widening works. Because of the short construction period (approximately 6 to 7
months), together with staged construction sequence of works which will limit
the extent of construction area at any one time. Therefore, air quality is
monitored by means of checking the adequacy of dust mitigation measures
implemented by the Contractor (Please refer to Section 2.1 of the EM&A
Manual or Section 2.3.1 of this report for dust mitigation measures). It is
anticipated that proper implementation of dust reduction measures will be
adequate to mitigate dust impacts and maintain Total Suspended Particulate
(TSP) concentration levels within those recommended under the Air Quality
Objectives (AQO) and no further air quality monitoring will be necessary.
All of the dust
monitoring locations identified in the EIA Study is located in the vicinity of
the proposed vehicular underpass (located at the Salisbury Road/Chatham Road
South junction), the monitoring works of which will be carried out as part of
the works east of Nathan Road by KCRC. Hence, the standard requirements of
collating Baseline Monitoring Results, calculation of Action and Limit Levels
etc. have been omitted from this report. These requirements will be fulfilled
under the EM&A for the works east of Nathan Road.
Should there be
any obvious air quality deterioration as a result of the construction works,
the ET will perform additional monitoring (for example, using air quality monitoring equipment) to
measure TSP concentration levels so as to ensure that any deteriorating air
quality can be readily detected and timely action is to be taken to rectify the
situation. Additional monitoring will be performed by the ET in the event of
complaints from the local residents.
2.1.1 Air Sensitive Receivers
According to Section 7.4 of the EIA
Report, Peninsula Hotel, YMCA Hotel, Space Museum, Museum of Art and Hong Kong
Cultural Centre are identified as air sensitive receivers. Their locations are
shown in Appendix D.
2.2 Noise
Though
requirements for noise monitoring has not been specified in the EM&A
Manual, during the course of site inspection carried out by the ET, the ET will
closely monitor construction noise. Should there be any obvious indication of
construction noise level exceedance observed by the ET during site inspections,
the ET will perform additional monitoring and will carry out noise monitoring
works to measure the exceedance of noise level, with reference to the Noise
Control Ordinance. Measurement of construction noise level will be carried out using
an Integrating Sound Level Meter with calibrator which complied with EPD's
requirements. Additional
monitoring will be performed by the ET in the event of complaints from the
local residents.
2.2.1 Noise Sensitive Receivers
According to Section 4.3 of the EIA
Report, the noise standards only apply to dwellings relying on opened windows
for ventilation. Since central air conditioning systems are provided for all
hotels which do not rely on openable windows for ventilation, these noise
sensitive receivers are less sensitive to noise impacts.
2.3 Environmental Mitigation Measures
2.3.1 Air Quality
Dust control and
mitigation measures to be implemented during the construction phase are listed
in Section 2.1 of the EM&A Manual. The Contractor should:
·
Use of regular watering to reduce dust emissions from exposed site
surfaces and unpaved roads, with complete coverage, particularly during dry
weather;
·
Use of frequent watering for
particularly dusty static construction areas and areas close to air quality
sensitive receivers;
·
Side enclosure and covering of any
aggregate or dusty material storage piles to reduce emissions. Where this is
not practicable owing to frequent usage, watering should be employed to
aggregate fines;
·
Tarpaulin covering of all dusty vehicle
loads transported to, from and between site locations;
·
Establishment and use of vehicle wheel
and body washing facilities at the exit points of the site, combined with
cleaning of public roads where necessary;
·
Imposition of speed controls for
vehicles and unpaved site roads;
·
Where feasible, routing of vehicles and
positioning of construction plant should be at maximum possible distance from
air quality sensitive receivers; and
·
Instigation of an environmental monitoring
and auditing program to monitor the construction process in order to enforce
controls and modify methods of work if dusty conditions arise.
According to
Section 1.3 of the EM&A Manual, it is anticipated that proper
implementation of dust reduction measures will be adequate to mitigate dust
impacts and maintain TSP concentration levels within those recommended under
the Air Quality Objectives (AQO), and no further air quality monitoring will be
necessary.
Site inspection
is carried out by the ET at least once per week according to Section 4.1 of the
EM&A Manual. During the course of site inspection, the ET will check if the
Contractor implements the aforementioned dust mitigation measures during
construction phase.
Violation of EM&A requirements and/or complaints
on air quality
Should the
Contractor does not implement the aforementioned dust mitigation measures
properly during construction phase and resulting in deterioration of air
quality, and/or complaints (including verbal complaints) are received from
local residents, the ET will perform TSP concentration level measurement.
·
Monitoring
methodology
The Total
Suspended Particulate (TSP) concentration levels are sampled by drawing air
through a piece of conditioned and pre-weighed filter paper inside the High
Volume Sampler at controlled flow rate. After sampling, the filter paper with
the retained particulate is further conditioned and weighed. The TSP level is
calculated from the ratio of the mass of particulate retained on the filter
paper to the total volume of air sampled.
·
Monitoring
equipment
High Volume
Sampler (Model no. GMW SA2310-105) will be used for TSP concentration levels
measurement. Its associated calibrator (Model no. Anderson G3357K S/N: F31/42J)
will be used for calibration.
·
Monitoring
parameters
1.
24-hour
TSP concentration level for every week
2.
3x1-hour
TSP concentration level for every six days
If TSP concentration levels exceed their
respective allowable limits, timely action will be taken to rectify the
situation.
2.3.2 Noise
During the
course of site inspection, the ET will closely monitor construction noise.
Construction noise level exceedance and/or complaints
on construction noise
Should there be
any obvious indication of construction noise level exceedance observed by the
ET during site inspections, and/or complaints (including verbal complaints) are
received from local residents, the ET will perform construction noise
measurement.
·
Monitoring
methodology
The construction
noise levels are measured in terms of the A-weighted equivalent continuous
sound pressure level (Leq). Leq (30 min) is taken as the
monitoring parameter for the time period between 0700-1900 hours on normal weekdays
during normal hours (0700-1900 Monday to Saturday excluding public holidays). Leq
(30 min) is monitored as 6 consecutive Leq (5 min) readings.
·
Monitoring
equipment
Integrating
Sound Level Meter (Model no. CESVA SC20-e) will be used for construction noise
level measurement. Its associated calibrator (Model no. CESVA CB-5) will be
used for calibration.
·
Monitoring
parameters
1.
Leq
(30 min) for the time period between 0700-1900 hours on normal weekdays
2.
L10
and L90 (for reference)
If construction noise levels exceed
their the allowable limits, timely action will be taken to rectify the
situation.
2.4 Environmental
Requirements in Contract Documents
The EPD's standard pollution control clauses have been
incorporated into contract documents and regular auditing by the ET and the IEC
to ensure mitigation measures are properly implemented by the Contractor, and
will be sufficient to relieve dust impacts.
3.0 IMPLEMENTATION
STATUS - Advice on the implementation of
environmental mitigation measures
Implementation Schedule of Environmental Mitigation
Measures is shown in Appendix E.
4.0 ENVIRONMNETAL STATUS AND MONITORING RESULTS
4.1 Air
Quality
As the mitigation measures implemented by the
Contractor during site inspections are adequate, no TSP level has to be
recorded. Please refer to photos in Appendix F for implementation of dust
reduction measures done by the Contractor.
Photos in
Appendix F show the environmental mitigation measures implemented by the
Contractor to control dust emissions during this reporting period.
Photo 1 shows
excavated materials to be transported to dumping site being covered with
tarpaulin covering, which can effectively reduce dust emissions during
transportation of dusty materials.
Photo 2 shows
removal of excavated materials from roadside, which can avoid dust emissions by
speedy vehicles.
Photo 3 shows screening of the construction site with
hoardings to reduce dust emissions during the construction phase. However, the
excavated site is not covered with tarpaulin. In order to minimise dust
emissions, the Contractor later covers the excavated site and dusty material
stockpiles with tarpaulin (Photo 4).
4.2 Noise
No obvious noise level exceedance was observed during
site inspections.
4.3 Adverse
effects on Air Quality and Noise Level from Non-construction Activities and/or
Activities from other Construction Sites
During the course of site inspection, no adverse
effects on air quality and noise level due to non-construction activities
and/or activities from other construction sites were observed.
5.0 RECORD
OF NON-COMPLIANCE, COMPLAINTS, NOTIFICATIONS OF SUMMONS AND SUCCESSFUL
PROSECUTIONS
5.1 Non-compliance
5.1.1 Air Quality
No non-compliance was identified during site
inspections as the mitigation measures implemented by the Contractor during
site inspections are adequate.
5.1.2 Noise
No non-compliance in construction noise level was
observed during site inspections.
5.2 Complaints
and Verbal Complaints
No
complaint and verbal complaint were received in the reporting month.
5.3 Notifications
of Summons and Successful Prosecutions

of summons or successful prosecutions were received in the reporting
month.
6.0 FUTURE KEY ISSUES
The proposed
construction works to be carried out in the next reporting period (April 2002)
are as follows:
·
ATC and street lighting drawpit/ ducting
·
Drainage works
·
Resurfacing and reconstruction works along southboard Salisbury Road
·
Street lighting diversion at footpath area
·
Reinstatement of pavement area
·
Road signage at footpath area
Some of them may
have potential environmental impact and will require mitigation measures, and
such activities will be monitored closely during future site inspections.
7.0 ADVICE
ON THE SOLID AND LIQUID WASTE MANAGEMENT STATUS
The waste management plan
has been submitted in this reporting period. The Contractor has carried out
construction works in accordance with Waste Management Plan.
7.1 Excess
Excavated Materials
The Contractor stockpiles
excavated materials which will be reused for landscaping and backfilling
temporarily on site. These excavated materials are covered with tarpaulin
(please refer to Photo 4 of Appendix F for reference).
Excavated materials which
cannot be reused for backfilling were transported to either Tseung Kwan O
public filling area or Tolo Harbour Reclamation Area, according to the Waste
Management Plan. Such materials were covered with tarpaulin, which could effectively
reduce dust emissions during transportation (please refer to Photo 1 of
Appendix F for reference).
7.2 Construction
Waste
According to the Waste
Management Plan, the Contractor separated construction waste which could be reused
on site and recycled with those to be disposed of. This was carried out by
general workforce under supervision of Foremen and charge hands. For example,
timber (for formwork) was cleaned for reuse, steel was stored for reuse,
reinforcement was sorted into usable lengths for recycling or reuse on site.
7.3 Demolition
Waste
None of the demolition
waste generated in the captioned project will be reused, according to the Waste
Management Plan. Such waste is transported to either Tseung Kwan O public filling
area or Tolo Harbour Reclamation Area.
7.4 Chemical
Waste
No chemical waste is
generated in the captioned project.
7.5 General
Refuse
The Contractor deposited
aluminium cans, plastic bottles and glass bottles in separately labelled bins for
recycling and reuse.
The
Contractor reduced office wastes through recycling of paper. Signs encouraging
environmental awareness, such as reducing the number of photocopies to a
minimum and using both sides of papers, etc., were put on in the Contractor’s
site office.
8.0 SUBMISSION OF SITE INSPECTION PROFORMA
Site
inspection proforma for March 2002 is attached in Appendix G. Locations of
deficiencies are shown on the site plan attached in Appendix G.
A
standard site audit checklist is attached in Appendix H.
Weather
condition during all site inspections carried out in March 2002 is fine. Wind
is minimal.
8.1 Potential
Environmental Impact
According
to the site inspection proforma for March 2002, the following deficiencies are
recorded:
1.
Site hoardings are erected
on only 3 sides of the site.
2.
Some heaps of excavated
materials are not covered.
If site
hoardings are not erected to screen all sides of the site, and heaps of
excavated materials are not covered, dust emission from the excavated area and
the excavated materials may have adverse influence on air quality.
8.2 Mitigation
Measures
In order
to mitigate the environmental impacts as described in Section 8.1, the
Contractor had been advised to erect site hoardings on all 4 sides of the site
so as to completely screen the site, and to cover heaps of excavated materials
with tarpaulin so as to reduce dust emissions.
