5.1.1.1
Waste management during the construction phase will mainly
be the responsibility of the Contractor, who should implement the mitigation
measures recommended in the EIA report in order to minimise waste or resolve the
issues associated with the management of wastes. The Contractor should also ensure that
all wastes produced during the construction phase are handled, stored and
disposed of in accordance with good waste management practices, relevant
legislation and waste management guidelines. Wastes generated from the construction
activities, such as the construction and demolition (C&D) materials, should
be audited at regular intervals to ensure that proper storage, transportation
and disposal practices are undertaken.
Such audit would ensure the wastes generated to be properly disposed. Large quantities of wastes are not
expected to be generated from the operational phase of the EMSD Hong Kong
Workshop Project and no adverse environmental impacts would arise with the
implementation of good waste management practices. Therefore, an audit programme for the
operational phase will not be required.
5.2.1.1
With the proper handling, storage and disposal of wastes
arising from the construction works as recommended in the EMIS in Appendix 1.1 of this EM&A Manual,
the potential for adverse environmental impacts is minimised. During site inspections, the Engineer
and ET should pay special attention to the issues relating to the waste
management and check whether the Contractor has implemented the recommended
good site practices and other mitigation measures. The following waste management measures
should be implemented by the Contractor:
·
The requirements as stipulated in the ETWB TC(W) No.19/2005
Environmental Management on Construction Sites and the other relevant
guidelines should be included in the Particular Specification for the
Contractor as appropriate;
·
The Contractor should be requested to submit an outline Waste
management Plan (WMP) prior to the commencement of construction work, in
accordance with the ETWB TC(W) No.19/2005 so as to provide an overall framework
of waste management and reduction.
The WMP should include:
-
Waste management policy;
-
Record of generated waste;
-
Waste reduction target;
-
Waste reduction programme;
-
Role and responsibility of waste management team;
-
Benefit of waste management;
-
Analysis of waste materials;
-
Reuse, recycling and disposal plans;
-
Transportation process of waste products; and
-
Monitoring and action plan;
·
The waste management hierarchy (refer to the EIA report)
should be strictly followed. This
hierarchy should be adopted to evaluate the waste management options in order
to maximise the extent of waste reduction and cost reduction. The records of quantities of waste
generated, recycled and disposed (locations) should be properly documented;
·
A trip-ticket system should be established in accordance
with DevB TC(W) No. 6/2010 and Waste Disposal (Charges for Disposal of
Construction Waste) Regulation to monitor the disposal of public fill and solid
wastes at public filling facilities and landfills, and to control fly-tipping. A trip-ticket system would be included
as one of the contractual requirements for the Contractor to strictly
implement. The Engineer would also
regularly audit the effectiveness of the system; and
·
A recording system for the amount of waste generated, recycled
and disposed (locations) should be established. The Contractor should also provide
proper training to workers regarding the appropriate concepts of site
cleanliness and waste management procedures, e.g. waste reduction, reuse and
recycling all the time.
5.3.1.1
Regular audits and site inspections should be carried out by
the Engineer, ET and Contractor to ensure that the recommended good site
practices and other mitigation measures are implemented by the Contractor. The audits should look at all aspects of
on-site waste management practices including the waste generation, storage,
recycling, transport and disposal.
Apart from site inspections, documents including licenses, permits,
disposal and recycling records should be reviewed and audited for the compliance
with the legislation and contract requirements. The requirements of the environmental
audit programme are set out in this EM&A Manual. The audit programme will verify the
implementation status and evaluate the effectiveness of the mitigation
measures.
