1.         This Permit consists of three parts, namely, PART A (Main Permit), PART B (Description of Designated Project) and PART C (Permit Conditions). Any person relying on this permit should obtain independent legal advice on the legal implications under the Ordinance, and the following notes are for general information only.

2.         If there is a breach of any conditions of this Permit, the Director or his authorized officer may, with the consent of the Secretary for the Environment, order the cessation of associated work until the remedial action is taken in respect of the resultant environmental damage, and in that case the Permit Holder shall not carry out any associated works without the permission of the Director or his authorized officer.

3.         The Permit Holder may apply under Section 13 of the Ordinance to the Director for a variation of the conditions of this Permit. The Permit Holder shall replace the original permit displayed on the Project site by the amended permit.

4.         A person who assumes the responsibility for the whole or a part of the designated project may, before he assumes responsibility of the designated project, apply under Section 12 of the Ordinance to the Director for a further environmental permit.

5.         Under Section 14 of the Ordinance, the Director may with the consent of the Secretary for the Environment, suspend, vary or cancel this Permit. The suspended, varied or cancelled Permit shall be removed from display at the Project site.

6.         If this Permit is cancelled or surrendered during the Project, another environmental permit must be obtained under the Ordinance before the Project could be continued. It is an offence under Section 26(1) of the Ordinance to decommission a designated project listed in Part II of Schedule 2 of the Ordinance without a valid environmental permit.

7.         Any person who carries out the Project contrary to the conditions in the Permit, and is convicted of an offence under the Ordinance, is liable: -

8.         The Permit Holder may appeal against any condition of this Permit under Section 17 of the Ordinance within 30 days of receipt of this Permit.

9.         The Notes are for general reference only and that the Permit Holder should refer to the EIA Ordinance for details and seek independent legal advice.

10.     Occupational safety and health issues are governed by the Occupational Safety and Health Ordinance (Cap. 509), and Factories and Industrial Undertakings Ordinance (Cap.59).

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.

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.

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.
