Metals

Toxicity Characteristics Leaching Procedure (TCLP) test for materials contaminated with heavy metals needs to be carried out in accordance with the testing frequency and requirements as stipulated in EPD¡¦s Guidance Notes for Investigation and Remediation of Contaminated Sites.

TPH and PAH

Toxicity Characteristic Leaching Procedure (TCLP) tests for TPH, PAH and BTEX contaminated materials have to be carried out according to the testing frequency and requirements as stipulated in EPD¡¦s ¡§Guidance Notes for Investigation and Remediation of Contaminated Sites.  Pre-treatment is required to bring levels of TPH to below the TCLP limit of 2,500ppm PAH/BTEX to below the TCLP limit 1,000ppm.

Dioxins and Furans (PCDD/PCDF)

Toxicity Characteristic Leaching Procedure (TCLP) tests for PCDD/PCDF contaminated materials have to be carried out with reference to the requirements as stipulated in EPD¡¦s Guidance Notes for Investigation and Remediation of Contaminated Sites.  Pre-treatment is required to bring levels of PCDD/PCDF to below the TCLP limit of 1ppb PCDD/PCDF (TEQ), subject to TCLP confirmation at a frequency of 1 sample per 100 tonnes of stabilised materials.

N.B.

TEQ      =        toxicity equivalent units.

ppm       =       mg/kg           (miligrams / kilogram)

ppm       =       mg/g               (micrograms / gram)

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.

Typical Site Layout[2]

A schematic layout of a typical arrangement for all the works including excavation, cement solidification plant, biopile and stockpiling areas for different types of soil is shown in Graphic C2.

Note:       (1)   Universal Treatment Standard: US 40 CFR 268.48.

(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.
