The anticipated quantities of construction waste (400 m3),
chemical wastes (a few hundred litres, mainly are used lube oils), sewage (1 m3
per day) and general refuse (26 kg per day) to be generated during the
construction phase of the Project will be small. With the implementation of the general good
construction site practices, the construction of the Project will not cause
adverse waste management or environmental impacts with respect to the criteria
specified in the EIAO-TM.
The good construction site practices are further described below and the
Contractor must ensure that all the necessary waste disposal permits or
licences are obtained prior to the commencement of the construction works.
7.2.1
Construction Waste
Wherever practicable, the excavated soil will be segregated from other
wastes to avoid contamination, and reused on-site for the site formation works
to reduce the amount of construction waste to be disposed off-site.
The Contractor must ensure that no waste, spoil or excavated materials
arising from the Project will be improperly dumped in the Hei
Ling Chau Island, in particular the environmental
sensitive area/ecological habitat identified in the Section 5 of the EIA Report.
7.2.2
Chemical Waste
The construction contractor will be registered as a chemical waste
producer with the EPD. Chemical waste
will be handled in accordance with the Code
of Practice on the Packaging, Handling and Storage of Chemical Wastes.
7.2.3
Management of Waste Disposal
The construction contractor will open a billing account with the EPD in
accordance with the Waste Disposal
(Charges for Disposal of Construction Waste) Regulation. Every construction waste or public fill load
to be transferred to the Hei Ling Chau
Refuse Transfer Station will require a valid “chit”.
A trip-ticket system will also be established in accordance with Works Bureau Technical Circular No.31/2004
to monitor the disposal of construction waste at the Hei
Ling Chau Refuse Transfer Station, and to control
fly-tipping. The trip-ticket system will
be included as one of the contractual requirements and implemented by the
Contractor.
7.2.4
Staff Training
At the commencement of the construction works, training will be provided
to workers on the concepts of site cleanliness and on appropriate waste
management procedures, including waste reduction, reuse and recycling.
Monthly site audits of the waste management practices will be carried
out during the construction phase to determine if wastes are being managed in
accordance with the good site practices described in this EIA Report. The audits will
examine all aspects of waste management including waste generation, storage,
recycling, transport and disposal.
