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.

(2) For other RBRGs metal contaminants Cobalt,
Copper, Manganese, Molybdenum and Tin, they must be reduced by at least 90
percent in mobility for respective metals through cement solidification remediation
treatment. The reduction of mobility of metal contaminants (leachable metals
contaminants) should be confirmed through TCLP tests (i.e. to carry out TCLP
test for the untreated soil and for the soil after treatment and to compare the
concentrations of the metals in the leachates).
(3) The TCLP test for the concerned metal(s)
will be tested both for untreated soil and for soil after treatment in order to
confirm that the requirement of Note (2) can be complied with (i.e. reduced by
at least 90 percent in mobility for the respective metal(s) through cement
solidification remediation treatment).

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.
