required in above Conditions 2.18(b) and (c). Duplicate samples of the treated
soil may need to be collected for parallel testing by another qualified
laboratory if requested by the Director.
2.19
Prior to backfilling the respective excavation zones
with treated soil, confirmatory sampling shall be conducted to confirm that all
contaminated soil has been removed. The confirmatory sampling will be conducted
in accordance with the requirements stipulated in Section 4.3.3. of CAR/RAP in
Appendix 7.2 of the EIA Report (Register No. AEIAR-188/2015) to meet the Risk
Based Remediation Goals (“RBRG”) Standards as shown in Appendix
E of this Permit. Duplicate samples of the soil may need to be
collected for parallel testing by another qualified laboratory if requested by
the Director.
Mitigation
and Precautionary Measures
2.20
The following measures shall be implemented to
prevent pollution, control nuisances, and reduce risk during the remediation
phases:
(a)
Control on active works area (i.e.
area with concrete paving material removed and without any cover)
The Permit Holder shall, at least one month
before commencement of excavation works, submit to the Director for approval
four hard copies and one electronic copy of an Air Quality Management Plan
(AQMP). The AQMP shall confirm on
the schedule and zonings for active works area and specify the maximum
allowable size of active works area in operation for the respective zone and
total active works area at any one time over the entire Project site for better
control on the potential emission of hydrocarbons, heavy metals
and fugitive dusts. The maximum
allowable sizes of active works areas shall be complied with during the
excavation works;
(b)
Dust suppression measures
All active works areas shall be sprayed with water frequently at no
less than once every 2.5 hours. All stockpiled soil shall be covered with
tarpaulin or other impermeable material to minimise potential emissions of
fugitive dust, heavy metals and hydrocarbons.;
(c)
Control measures during remediation by biopile
method:
i) During biopile operation, the biopiles
shall be enclosed by impervious membrane during bio-degradation process and
activated carbon filters with an installed removal efficiency of at least 99%
of Volatile Organic Compounds (VOC) shall be fitted to the pipe outlet(s) of
the biopile(s);
ii) Emissions from the biopile
pipe outlet(s) shall be regularly monitored by a Continuous Emission Monitoring
System to check the performance of the activated carbon filter system; and
iii) Spent activated carbon filter shall
be replaced regularly to ensure that the measured total Volatile Organic
Compounds (VOC) emission concentration from the system is below 20 ppm; and
iv) The extraction pump and/or blower for
the biopile pipe network shall be switched off to stop system discharge
emission when exceedance of the monitored total VOC limit of 20 mg/m3
is detected and/or unacceptable air quality is monitored at the site boundary.
Resumption of biopile system discharge emission shall only be allowed after
confirmation and implementation of appropriate mitigation measures, e.g. replacement of the activated carbon filter;
(d)
Control measures during remediation by cement
solidification method:
The cement solidification process and the associated storage bins shall
be fully enclosed. Any storage
piles shall be covered with tarpaulin or other impermeable material. Soils that
require both hydrocarbons (HC) and heavy metals (HM) remediation will first go
through HC remediation by biopiling and then through
HM remediation by cement solidification; and
(e)
The Key Mitigation Measures as stated in Appendix C of this Permit shall be implemented.
Submission of Landscape Plan
2.21
To reduce the landscape impact due to the Project,
four hard copies and one electronic copy of a Landscape Plan, at least one
month before the commencement of corresponding parts of landscape works of the
Project, shall be deposited with the Director. The Plan shall include the design
details, locations, implementation programme, maintenance and management
schedules, and drawings in the scale of 1:1,000 or other appropriate scale as
agreed by the Director of the landscape mitigation measures of the Project as
recommended in the EIA Report (Register No.: AEIAR – 188/2015). In particular,
the Landscape Plan shall show the design of the waterfront promenade and
details of the tree compensatory proposal. Compensatory tree planting with a
minimum ratio of 1:1 in terms of quantity shall be provided in the proposed
future waterfront promenade.
Submission
of Remediation Report(s)
2.22
Six hard copies and one electronic copy of Remediation
Report(s) shall be submitted to the Director for approval after the completion
of the remediation of corresponding areas of the Project. The Remediation Report(s) shall
demonstrate that the remediation for the site area that it covers has been
undertaken according to the specified methodology and has met the treatment
Goals at Appendix E for the intended land use, i.e. Urban Residential, Rural Residential, Industrial or
Public Parks, known at the time of submission. The Remediation Report(s) shall
be submitted at least four weeks before the concerned area(s) of Phase 2 of the
Project is/are handed over to other parties for redevelopment.
Measures
for Works in all Phases
2.23
Mitigation measures shall be implemented to prevent
other demolition related nuisances throughout the demolition and remediation
phases, in accordance with the EIA Report (Register No. AEIAR-058/2002),
including but not limited to the following:
(a)
provide boundary hoarding of height not less than
5.5 meters measured from street level modified to perimeter noise barrier form,
and made of panels with superficial surface density not less than 10 kg/m2;
(b)
provide moveable noise barriers close to powered
mechanical equipment (PME) in cases where, in the opinion of the ET leader, IEC
or the Director, such PME has the potential to cause excessive noise nuisance
to sensitive receivers and where a benefit will result from providing the barriers;
(c)
if necessary, in addition to the Conditions 2.23(a)
and (b) above, modify continuous operational periods for noisy plant or take
other measures to comply with the construction noise criteria;
(d)
use adequately designed and maintained perimeter channels,

For Phase 2 of the Project
Remediation Methods[1]
The following remediation methods are recommended for
the 3 different types of contaminated soil:
¡ Type
A contaminated soil (Heavy Metals): Cement solidification, test, on-site
backfilling.
¡ Type
B contaminated soil (Hydrocarbons): Biopiling, test,
on-site backfilling.
¡ Type
C contaminated soil (Heavy Metals and Hydrocarbons): Biopiling
followed by cement solidification, test, on-site backfilling.
The contaminated soil would be excavated and transported
to the corresponding designated areas on-site for appropriate remediation.
Trucks would carry the excavated contaminated soil into the stockpiling areas
or remediation works areas for temporary storage or treatment respectively. Graphic C1
indicates the workflow during remediation works.

Key Mitigation Measures[5]
During excavation, the Contractor shall adopt the following measures:
¡ Properly
design and execute excavation profile;
¡ Fence
off the contaminated area throughout the period of remediation works;
¡ Take
precautions when controlling ground settlement, groundwater and wastewater;
¡ Avoid
temporary stockpiling as far as practical. In case temporary storage is needed,
contaminated soil should be placed in designated area paved with either
concrete or lined with impermeable sheeting, bunded and covered properly with
tarpaulins to prevent cross-contamination of different types of contaminated soil;
¡ Supply
of suitable backfill materials after excavation;
¡ Implement
speed control for vehicles travelling on site;
¡ Properly
decontaminate machineries and vehicles before excavating or taking different
contaminated soil and leaving the excavation zone.
The following mitigation measures shall be followed
during remediation works:
¡ The
loading, unloading, handling and storage of cement should be carried out in an
enclosed environment;
¡ The
loading, unloading, handling, transfer or storage of
materials that may generate airborne dust emissions such as untreated soil and
oversize materials sorted out from screening plant and stabilised
soil stockpiled in designated area should be carried out in such a manner to
prevent or minimise dust emissions.
¡ All
practical measures, including but not limited to speed control for vehicles,
should be taken to minimise dust emissions;
¡ Simultaneous
operation of mixing facilities and other equipment shall be avoided as far as
possible to minimise unnecessary generation of noise nuisance;
¡ Stockpile
of untreated soil shall be covered as far as practicable;
¡ Treated
oversize materials can be used as backfilling material for on-site backfilling.
Sorted materials of size smaller than 5cm will be collected and transferred to
the mixing plant for further remediation;
¡ Treated
soils can be broken down into suitable size for on-site backfilling purpose;
¡ Water
used in installation of pipe piles should as far as practicable be recirculated
after sedimentation. Excess wastewater should go through silt removal
facilities before discharge. The Contractor would be required to obtain a
license from EPD under the WPCO for discharge to the public drainage system.
¡ Housekeeping
should be maintained at all times at the mixing plant as well as among other
remediation facilities;
¡ Visual
inspection and rinsing (if needed) of any contaminated soil adhered on the
broken concrete slab surface are recommended; and
¡ A
clear separation between treated and untreated materials is recommended.
Furthermore, physical separation of the temporary stockpiles of different types
of soils in clearly designated areas with appropriate signage and fencing
should be provided.
