7                                Waste Implication

7.1                         Introduction

The quantity and timing for the generation of waste during the construction phase have been estimated. Measures including the opportunity for on-site sorting, reusing excavated materials etc, are devised in the construction methodology to minimise the surplus materials to be disposed off-site.  Proper disposal of chemical waste should be via a licensed waste collector.

7.2                         Mitigation Measures

All the proposed mitigation measures are stipulated in the EIA Report and summarised in the Project Implementation Schedule (PIS) in Appendix 2-2.

EM&A requirements are required for waste management during the construction phase only and the effective management of waste arising during the construction phase will be monitored through the site audit programme.  The aims of the waste audit are:

·         To ensure the waste arising from the works are handled, stored, collected, transferred and disposed of in an environmentally acceptable manner; and

·         To encourage the reuse and recycling of material.

The types and quantities of waste that would be generated during the operational phase have been assessed.  It is anticipated there would not be any insurmountable impacts during the operational phase.  A trip-ticket system should be operated to monitor all movements of chemical wastes which will be collected by a licensed collector to a licensed facility for final treatment and disposal.  Recommendations have been made to ensure proper treatment and proper disposal of these wastes in the EIA Report and summarised in the Project Implementation Schedule (PIS)  in Appendix 2-2.  

7.3                         Waste EM&A Requirements

The Contractor shall be required to pay attention to the environmental standard and guidelines and carry out appropriate waste management and obtain the relevant licence/permits for waste disposal.  The ET shall ensure that the Contractor has obtained from the appropriate authorities the necessary waste disposal permits or licences including:

·         Chemical Waste Permits/licenses under the Waste Disposal Ordinance (Cap 354);

·         Public Dumping Licence under the Land (Miscellaneous Provisions) Ordinance (Cap 28);

·         Marine Dumping Permit under the Dumping at Sea Ordinance (Cap 466); and

·         Effluent Discharge Licence under the Water Pollution Control Ordinance.

The Contractor shall refer to the relevant booklets issued by the DEP when applying for the license/permit and the ET shall refer to these booklets for auditing purposes.

Regular audits and site inspections at least once per week should be carried out during construction phase by the ET to ensure that the recommended good site practices and other recommended mitigation measures are properly implemented by the Contractor.  The audits should concern all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal.  Apart from site inspection, documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation and contract requirements.

The requirements of the environmental audit programme are set out in Section 13 of this Manual.  The audit programme will verify the implementation status and evaluate the effectiveness of the mitigation measures.
