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

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.
(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.
(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.
(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.
(k)
No temporary use, to
include site office and storage of common construction material, at the Phase 1
Site shall be allowed until Remediation Report(s) has been deposited with the
Director in accordance with Condition 2.17 below after the completion of
the remediation and disposal of dioxin/furan contaminated wastes at specific
site areas proposed for temporary use.
(l)
No temporary use, to
include site office and storage of common construction material, at the Phase 1
Site shall be allowed until the identified locations for such temporary uses
have been provided with the pre-requisite additional concrete paving as
stipulated in Condition 2.5(j) above.
(m)
