This section sets out the handling, recycling, storage, transportation and disposal measures which are recommended to avoid or minimise potential adverse impacts associated with waste arising from the construction of the Designated and Potentially Designated Elements.
8.2
Waste Management Practices
The Construction Contractor(s) should incorporate these recommendations into a Waste Management Plan for the construction phase of the Project. Such a management plan should incorporate site specific factors, such as the designation of areas for the segregation and temporary storage of reusable and recyclable materials.
Possible waste arising during the construction phase will include dredged/excavated sediment, construction waste, chemical waste and general refuse.
The Implementation Schedule in Annex E,
provides details on the appropriate mitigation measures for avoiding and minimising potential adverse impacts associated with waste arising
from the construction of the Project and the associated developments. The Waste Management Plan should be
refined and updated as more detailed information is generated on the volume of
dredged/excavated sediment. Similarly, it should be regularly reviewed, and
updated as appropriate, throughout the course of the construction works to
ensure that it remains current with the latest detailed information and works
practices.
It is the Contractor’s responsibility to ensure that only approved licensed waste collectors are used and that appropriate measures to minimise adverse impacts, including windblown litter and dust from the transportation of these wastes are employed. In addition, the contractor must ensure that all the necessary waste disposal permits are obtained and complied with.
The Waste Management Plan should also outline the requirements for a waste audit programme to ensure the measures outlined in the plan are effectively implemented and adhered too.
In order to ensure that the Contractor has implemented the recommendations of the EIA, the IEC shall conduct regular site audits of each of the waste streams, to determine if wastes are being managed in accordance with the approved procedures and the site waste management plan. The scope of the waste management audits is presented below.
8.3.1 Objectives of the Waste Audit
The aims of the waste management audit will include, but are not limited to, the following:
· ensuring that the wastes arising from works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner and comply with the relevant requirements under the Waste Disposal Ordinance (WDO) and its regulations;
· ensuring that the Contractor properly implements the appropriate environmental protection and waste pollution control mitigation measures, as outlined in the Implementation Schedule (Annex E) to minimise and control the potential for waste impacts;
· ensuring the effective implementation of the Contractor’s Environmental Management System (EMS) and waste management plan;
· ensure the Contractor(s) enforce strict application of the public fill license and monitor the material placed in the reclamation and barges to control disposal of unauthorised material. Also to ensure the Contractor provide floating booms and collect any floating materials on a daily basis at the public filling area.
· to monitor the disposal of construction and demolition material and solid wastes at public filling facilities and landfills, and to control fly-tipping, a trip-ticket system should be included as one of the contractual requirements and implemented by the Environmental Team during the EM&A programme. The IEC should be responsible for auditing the result of the system; and
· to encourage the reuse and recycling of materials.
8.3.2 Methodology and Criteria
The Contractor should ensure that the necessary waste disposal permits or licences are obtained from appropriate authorities in accordance with the various Ordinances. In addition to the IEC audits, the Contractor and his ET Leader should also regularly inspect and audit the waste management practices on site with reference to the recommendations given in the Implementation Schedule contained in Annex E.
