8.1.1.1
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 KTE 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.
8.2
Mitigation Measures
8.2.1.1
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 ER 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:
(i) 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;
(ii) The Contractor should be requested to submit an outline 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;
(iii) The waste management hierarchy (refer to Section 10 of 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;
(iv) A trip-ticket system should be established in accordance with ETWB(W) 31/2004 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
(v) A recording system for the amount of waste generated, recycled and disposed (locations) should be established. The future 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.
8.3
Audit Requirements
8.3.1.1
Regular audits and site inspections should be carried out by
the ER, 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 Section 10 of this EM&A Manual. The audit programme will verify the
implementation status and evaluate the effectiveness of the mitigation
measures.
