Phased Approach for Implementing the Project and Implementation Requirements

2.5               The Project shall be implemented in two Phases with the following conditions.

Phase 1 Part 1

(a)        The Site area for both Part 1 and Part 2 of Phase 1 of the Project is shown in Figure 2 of this Permit.  At the time of notification of commencement of Phase 1 Part 1 of the Project as required under Condition 1.12, the Permit Holder shall deposit with the Director an updated Project programme, to be accompanied by layout plans with detailed descriptions and drawings of mitigation measures in scale of 1:1000 or in other suitable scale as agreed by the Director, showing clearly the relevant works in Phase 1 Part 1 of the Project.

(b)        Phase 1 Part 1 of the Project includes demolition and clearance of all existing chimneys, buildings and ancillary structures above the existing concrete ground slab in the Phase 1 Site area where the former Kennedy Town Incinerator Plant (KTIP) and the Kennedy Town Abattoir (KTA) are located.  The Phase 1 Part 1 also includes the removal of asbestos containing materials and dioxin/furan contaminated wastes within the Phase 1 Site.

(c)        Hoardings shall be erected around the Phase 1 Site at the commencement of Phase 1 Part 1 of the Project and shall be properly maintained throughout Phase 1 of the Project to restrict access of the Phase 1 Site to only authorized site staffs and workers.

(d)        Throughout Phase 1 Part 1, the existing concrete ground slab within the Phase 1 Site shall not be demolished but shall be retained intact as far as practicable.  Before completion of the Phase 1 Part 1 of the Project, inspection shall be carried out on the condition of the existing concrete ground slab and existing drainage system with the view to identify and repair any surface cracks such that their structural integrity is maintained to avoid exposing the soil underneath as far as practicable.  Such inspection and repair shall be carried out every month thereafter until the commencement of Phase 1 Part 2 of the Project.  Where the inspection and repair work fall within the reporting month of the monthly Environmental Monitoring & Audit (EM&A) report described under Condition 3.5 of this Permit, the inspection findings and repair work carried out shall be reported in that monthly EM&A report.

(e)        With the exception of drainage facilities required for the proper function of the site drainage system, the existing underground facilities such as refuse bunkers, lift pits, underground chambers and openings, and sub-sided areas within the Phase 1 Site area shall be cleaned up and backfilled with clean soil to about 130 mm from the top level of adjacent ground slab.  A layer of concrete cover of not less than 130 mm thickness shall then be laid on top of the clean soil to fill up the underground facilities such that the top level of the concrete cover on top of the clean soil above the underground facilities matches the top level of adjacent ground slab. Before completion of the Phase 1 Part 1 of the Project, inspection shall be carried out on the condition of the concrete covers and existing drainage facilities retained for the proper function of the site drainage system, with the view to identify and repair any surface cracks such that their structural integrity is maintained to avoid exposing the soil underneath as far as practicable.  Such inspection and repair shall be carried out every month thereafter until the commencement of Phase 1 Part 2 of the Project.  Where the inspection and repair work fall within the reporting month of the monthly Environmental Monitoring & Audit (EM&A) report described under Condition 3.5 of this Permit, the inspection findings and repair work carried out shall be reported in that monthly EM&A report.

(f)         Phase 1 Part 1 of the Project shall not involve any excavation work that may disturb or expose any part of the soil underneath the existing concrete slab.

Phase 1 Part 2

(g)        At the time of notification of commencement of Phase 1 Part 2 of the Project as required under Condition 1.12, the Permit Holder shall deposit with the Director a detailed updated Project programme, to be accompanied by layout plans with detailed descriptions and drawings of mitigation measures in scale of 1:1000 or in other suitable scale as agreed by the Director, showing clearly the relevant works in Phase 1 Part 2 of the Project.  The Project shall be implemented according to the updated programme.  The holder of Environmental Permit No. EP-313/2008 is required, through conditions under EP-313/2008 or any subsequent variations, to follow up with this condition during the temporary use of the Phase 1 site (which is named as “Works Area B” in the Environmental Permit No. EP-313/2008) for the construction of the WIL.

(h)        Phase 1 Part 2 of the Project includes the temporary use of the Phase 1 Site as site office and for the storage of common construction materials, the provision of mitigation measures to avoid any potential release of additional underground contaminants into the environment resulting from the above temporary use of the site, and the provision of mitigation measures to avoid impacts on workers on Phase 1 Site and the general public nearby, including residents and passers-by.  It also includes the removal of temporary site office and facilities for the storage of common construction materials before completion of the Phase 1 Part 2. The holder of Environmental Permit No. EP-313/2008 is required, through conditions under EP-313/2008 or any subsequent variations, to follow up with this condition during the temporary use of the Phase 1 site (which is named as “Works Area B” in the Environmental Permit No. EP-313/2008) for the construction of the WIL.

(i)          Under Phase 1 Part 2 of the Project, the Permit Holder shall not use or carry out any activity in the Phase 1 Site other than the site office and storage of common construction materials as proposed. The holder of Environmental Permit No. EP-313/2008 is required, through conditions under EP-313/2008 or any subsequent variations, to follow up with this condition during the temporary use of the Phase 1 site (which is named as “Works Area B” in the Environmental Permit No. EP-313/2008) for the construction of the WIL.

(j)          At locations within the Phase 1 Site area identified to be temporarily used as site office and for storage of common construction materials, an additional concrete paving of not less than 200 mm thickness shall be provided.  The indicative extent of this additional concrete paving, as extracted from the Application No. VEP-234/2007, is shown in Figure 3 of this Permit.

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)

ppb        =       ng/g              (nanograms / gram)

ppb        =       1000pg/g      (picograms / gram)
