Works Area
The
project works area is shown in Appendix C. The boundary of the works area to
the west of Nathan Road is also given in Appendix C.
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 limited the
extent of construction area at any one time. Therefore, air quality was
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). Proper implementation of dust reduction
measures was 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 was necessary.
All of the dust
monitoring locations identified in the EIA Study are 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 was fulfilled under
the EM&A for the works east of Nathan Road. Dust monitoring locations adjacent to the project
works area of the captioned project are shown in Appendix D.
Should there be
any obvious air quality deterioration as a result of the construction works,
the ET will perform additional monitoring using, for example, High Volume Sampler (HVS), 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.
According to
Section 4.1 of the EM&A Manual, regular site inspections are carried out by
the ET at least once per week.
Additional monitoring will be performed
by the ET in the event of complaints from the local residents, and/or any
obvious indication of deterioration of air quality is observed.
2.1.1 Air
Sensitive Receivers
According to Section 7.4 of the Final
EIA Report, Peninsula Hotel, YMCA Hotel, Hong Kong Space Museum, Museum of Art
and Hong Kong Cultural Centre are identified as air sensitive receivers. Their locations
are shown in Appendix E.
2.1.2 Air
Quality Monitoring
According to
Section 1.3 of the EM&A Manual, proper implementation of dust reduction
measures (see Section 2.1 of the EM&A Manual or Section 3.5 of the Final
EIA Report for details) was 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 was necessary.
Should the
Contractor does not implement appropriate dust mitigation measures properly
during construction phase and result 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
parameters
1. 24-hour TSP concentration level for
every week
2. 3x1-hour TSP concentration level for
every six days
2.1.3 Monitoring
Locations
Dust monitoring locations adjacent to
the project works area of the captioned project are shown in Appendix D. According
to Section 10.1.3 of the Final EIA Report, these dust monitoring locations are
closest to the air sensitive receivers affected by the captioned project.
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, and/or any
obvious indication of construction noise level exceedance is observed.
2.2.1 Noise Sensitive Receivers
According to Section 4.3 of the Final
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.
2.2.2 Noise Level Monitoring
During the
course of site inspection, the ET will closely monitor construction noise
levels.
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
parameters
1. Leq (30 min) for the time
period between 0700-1900 hours on normal weekdays
2. L10 and L90 (for
reference)
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 and Sections 3.5 and 10.1.7 of the Final EIA
Report. Some environmental mitigation measures are as follows:
·
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.
·
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.
2.3.2 Noise
According to
Section 4.4 of the Final EIA Report, construction noise level experienced by
the noise sensitive receivers surrounding the project works area are
significantly reduced by with window insulation and central air-conditioning.
If the Contractor implements good site practices listed in Appendix H of the
Final EIA Report, construction noise level experienced by the noise sensitive
receivers will be further reduced. Some of these good site practices are as
follows:
·
The Contractor shall comply with and observe the Noise Control Ordinance
and its subsidiary regulations in force in Hong Kong.
·
Before the commencement of any works,
the Engineer may require the methods of working, equipment and sound-reducing
intended to be used on the site to be made available for inspection and
approval to ensure that they are suitable for the project.
·
The Contractor shall devise, arrange
methods of working and carry out the Works in such a manner so as to minimise
noise impacts on the surrounding environment, and shall provide experienced
personnel with suitable training to ensure that these methods are implemented.
The noise reduction methods shall include, but not be limited to,
scheduling of works, siting of facilities, selection of quiet equipment, and
use of purpose-built acoustic panels and enclosures.
·
The Contractor shall ensure that all
plant and equipment to be used on site are properly maintained in good
operating condition and noisy construction activities shall be effectively sound-reduced
by means of silencers, mufflers, acoustic linings or shields, acoustic sheds or
screens or other means to avoid disturbance to any nearby noise sensitive
receivers.
An
implementation schedule of environmental mitigation measures is attached in
Appendix F.
3.1 Environmental
Mitigation Measures implemented by the Contractor during the Entire
Construction Period
The
Contractor implemented adequate environmental mitigation measures to reduce
dust emissions to the air sensitive receivers adjacent to the project works
area by:
·
Screening of the
construction site with hoardings to retain as much windblown dust within the
site area as possible.
·
Aesthetic treatment of the
hoardings to enhance their visual interest and harmony with surrounding
townscape.
·
Excavated materials loaded
on trucks and to be transported to dumping site were covered with tarpaulin,
which can effectively reduce dust emissions during transportation of dusty
materials.
·
Removal of surplus
excavated materials from roadside to avoid dust blown up by speedy vehicles.
·
Sand and aggregate
stockpiles temporarily stored on site was covered with tarpaulin to reduce windblown
dust.
·
Covering of the excavated
area with tarpaulin if work progress was not hindered.
·
Regular watering of the
exposed site surfaces, excavated materials and sand and aggregate stockpiles
temporarily stored on site.
The
aforementioned environmental mitigation measures are also listed in Section 2.1
of the EM&A Manual and Section 2.3 of this EM&A Report.
In all site inspections carried out during the entire
construction period, weather condition was mainly fine.
If adverse
weather conditions were encountered (rain, wind) was encountered on the
scheduled dates, site inspections were shifted one day.
4.1 Air
Quality
The Contractor had implemented adequate and effective
mitigation measures to reduce dust nuisance during execution of the Works
during the entire construction period. Mitigation measures undertaken by the
Contractor to minimise adverse dust impact on adjacent air sensitive receivers
are elaborated in Section 3.1 of this report.
One non-compliance item on air quality was identified
during the joint EM&A audit (the IEC, the Contractor and the ER) concluded
on July. No obvious air quality
deterioration was recorded during the entire construction period.
4.2 Noise
Since the number of powered mechanical equipment
utilised in the captioned project was small, no noise level exceedance was
observed in all site inspections performed during the entire construction
period.
No indication of noise exceedance was observed during
weekly site inspections during the entire construction period.
4.3 Adverse
effects on Air Quality and Noise Level from Non-construction Activities and/or
Activities from other Construction Sites
No adverse
effects on air quality and noise level due to non-construction activities
and/or activities from other construction sites were observed in all site
inspections performed during the entire construction period.
5.0 SUMMARY RECORD OF NON-COMPLIANCE, COMPLAINTS,
NOTIFICATIONS OF SUMMONS AND SUCCESSFUL PROSECUTIONS
5.1 Non-compliance
Three non-compliance items were identified during the
joint EM&A audit (the IEC, the Contractor and the ER) conducted on 4 July
2002.
Details of three non-compliance are stated as the
following:-
1) Aggregate
and the exposed site surfaces were not covered with tarpaulin.
2) No
drip trays were provided underneath chemical drums.
3) Tree
roots of the trees affected by the captioned project were not protected with
met Hessian bags.
5.2 Complaints
and Verbal Complaints
No
written and verbal complaints were received during the entire construction
period.
5.3 Notifications
of Summons and Successful Prosecutions
No notifications
of summons or successful prosecutions were received during the entire
construction period.
5.4 Review
of the Reasons for and the Implications of Non-compliances
5.4.1 Details of the Non-compliances
Details of the three non-compliances identified during
the joint EM&A audit (the IEC, the Contractor and the ER) conducted on 4 July
2002 are as follows:
1)
Aggregate and the exposed
site surfaces were not covered with tarpaulin.
2)
No drip trays were provided
underneath chemical drums.
3)
Tree roots of the trees
affected by the captioned project were not protected with wet Hessian bags.
Regarding non-compliance no. 1, uncovered aggregate
(and other materials) and exposed site surfaces may result in dust emission
nuisance due to strong wind and speedy passing vehicles.
Regarding non-compliance no. 2, not providing drip
trays underneath chemical drums cannot hold any leaked chemicals in case of
leakage, soil underneath and surrounding the chemical drums may be
contaminated.
Regarding non-compliance no. 3, health of the trees
without properly-protected roots may be adversely affected. The reason is that
unprotected tree roots are exposed to strong sunlight and therefore water
stored in the tree roots will be evaporated, and this may cause dewatering and
deterioration of the tree roots and more seriously, desiccation of the whole
tree structure. Regular watering can merely provide water to the tree roots,
but cannot protect the tree roots and cannot effectively reduce the amount of
water evaporated from the tree roots. Therefore covering the tree roots with
wet Hessian bags is the most effective measures to protect the tree roots and
minimise water lost from the tree roots due to evaporation.
5.4.2 Actions taken to rectify the
Non-compliances
During the site inspection on 8 July 2002, all
aggregates and the exposed site surfaces were observed being covered with
tarpaulin. The chemical drum had already been removed and relocated at Downer’s
site office.
During the site inspection on 29 July 2002, tree roots
of the trees affected by the captioned project had been wrapped with wet
Hessian bags.
5.5 Summary Description of
the Actions taken in the event of Non-compliance and any Follow-up Procedures
related to earlier Non-compliance
If an non-compliance item is identified during site inspection,
the ET Leader will sign a site inspection proforma. The site inspection
proforma records the location and description of the non-compliance identified
and will propose mitigation actions to rectify the non-compliance. Such
mitigation actions must be implemented and the non-compliance must be rectified
within the date of confirmation stipulated in the site inspection proforma.
During later site inspections and ad-hoc site
inspections, location of the non-compliance identified earlier is inspected to
see if mitigation actions have been properly implemented to rectify the
non-compliance. The Contractor is encouraged not to make the same
non-compliance and will be warned if new non-compliance is identified.
5.6 Summary Record of all
Complaints and Verbal Complaints received, Actions and Follow-up Procedures
taken
No written and
verbal complaints were received during the entire construction period.
5.7 Summary
of Notifications of Summons and Successful Prosecutions
No notifications of summons or successful prosecutions
were received during the entire construction period.
6.0 Notes on the Joint EM&A Audit Conducted on
7 August 2002
The joint EM&A audit (the IEC, the Contractor and
the ER) conducted on 7 August 2002, no non-compliance items were identified on
site.
Following up the last joint EM&A audit on 4 July
2002, the chemical drum had been removed from the site.
After the joint EM&A audit conducted on 7 August
2002, the Contractor was reminded to:
1)
Cover the exposed site surface
within the drainage works area with tarpaulin tauparlin; and
2)
Immediately remove small
piles of soil next to one of the trees.
7.0 REVIEW OF MONITORING METHODOLOGY ADOPTED
7.1 Air
Quality
According to Section 1.3 of the EM&A Manual or Section
2.1 of this report, due to the short construction period of the captioned
project (approximately 6 to 7 months), and application of staged construction
sequence to limit the extent of construction area at any one time, air quality
monitoring is carried out by means of checking the adequacy of dust mitigation
measures implemented by the Contractor, and rigorous air quality monitoring
(such as Total Suspended Particulate (TSP) level measurement using High Volume
Samplers (HVS)), is not required.
It can be concluded that air quality monitoring
methodology adopted in the captioned project is adequate. The reason is that
all of the dust monitoring locations identified in the EIA Study are located in
the vicinity of the proposed vehicular underpass located at the junction of
Salisbury Road and Chatham Road South, and the air quality monitoring works
have been carried out as part of the works east of Nathan Road by KCRC.
7.2 Noise
It can be concluded that noise monitoring methodology
adopted in the captioned project is adequate. Since duration of the captioned
project is short (approximately 6 to 7 months) and staged construction sequence
is adopted to limit the extent of construction area at any one time, total
number of construction plant and equipment is comparatively small.
Consequently, construction noise produced from these plant and equipment
produces relatively less adverse influence on the noise sensitive receivers.
8.0 REVIEW OF
THE PRACTICALLY AND EFFECTIVENESS OF the EIA PROCESS AND EM&A PROGRAMME
8.1 Effectiveness and
Efficiency of the Mitigation Measures
The
environmental mitigation measures implemented by the Contractor have been
elaborated in Section 3.1 of this report.
It can be concluded that these environmental mitigation measures are
effective in reduction of dust nuisance since covering of dusty materials with
tarpaulin and reducing dust emissions with water can effectively reduce the
amount of airborne dust produced by either strong wind or speedy vehicles.
9.0 ADVICE
ON THE SOLID AND LIQUID WASTE MANAGEMENT STATUS
The Contractor had carried
out adequate solid and liquid waste management during construction works in
accordance with the revised Waste Management Plan in August 2002.
9.1 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.
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.
9.2 Construction
Waste
According to the Waste
Management Plan, the Contractor separated construction wastes 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.
9.3 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.
9.4 Chemical
Waste
No chemical waste is
generated in the captioned project.
9.5 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.
10.0 CONCLUSION ON RETURN OF AMBIENT SCENARIO
Although
the captioned project had been completed on 30 August 2002, the ambient environmental
conditions have not been completely returned, the reasons are as follows:
1)
The DSD Contract DC/98/18
site just next to Tsim Sha Tsui Ferry Pier Bus Terminus emits odour and dust
frequently, which affects air quality.
2)
Construction of KCRC East
Rail Extensions at the junction of Nathan Road and Salisbury Road and at the
junction of Chatham Road and Salisbury Road produces dust and construction
noise, which may cause air quality deterioration and exceedance of construction
noise level.
3)
Traffic diversion due to
construction of KCRC East Rail Extensions may cause traffic congestion, which
hinders smooth flow of traffic. Internal combustion engines of temporary
stopping vehicles will emit more suspended particulates than those in vehicles
running non-stop.
Therefore,
it can be concluded that the ambient environmental conditions have not been
completely returned, though construction works of the captioned project had
been completed.
