1 INTRODUCTION

The Waste Management Plan (WMP) has been developed in accordance with clause 2.10 of Environmental Permit No. EP-353/2009/K, for the Highways Department Contract namely Contract No. HY/2019/01 Hong Kong-Zhuhai-Macao Bridge Hong Kong Boundary Crossing Facilities – Phase 2 and Other Works (hereinafter the Contract).

1.1 Project Description

China Harbour Engineering Company Limited (hereafter CHEC) is the Main Contractor to responsible for the execution of the construction works under Highways Department. The works mainly include the following works:

a) Landscaping and establishment works;

b) Irrigation system and associated drainage pumping system and facilities;

c) Erection and installation in the Passenger Clearance Building;

d) Public transport interchange (PTI) public toilet, satellite refuse collection point (RCP) and observation guard booths;

e) PTI cross boundary shuttle (CBS) / cross boundary coach (CBC) lanes and covered walkway;

f) Vehicle clearance plazas (VCP) vehicle kiosks and associated automatic vehicle clearance supporting system (AVCSS).

The main scope of works under the Contract does not include marine construction or vessel operation related to construction works.

1.2 Purpose of the Plan

This Waste Management Plan (WMP) aims to describe the arrangements for avoidance, minimization, handling, reuse, recovery and recycling, storage, transportation, collection, treatment and disposal of different categories of waste to be generated from the construction activities of this project. This WMP includes the recommended mitigations measures on waste management as contained as stipulated in EIA report and EM&A Manual. The main objectives of the WMP include:

· Providing reference to the waste management requirements, both statutory and non-statutory;

· Clarifying the responsibilities of each party on waste management and the personnel within the Contractor’s management; and

· Establishing the waste management procedures for avoidance, minimization, material reuse/recovery/recycling, collection, transportation, storage and disposal of wastes generated from the activities.

1.3 Environmental Management Policy

An Environmental Management Policy is established to demonstrate the Company’s commitment in improving environmental performance. It aims to communicate CHEC’s mission, vision and beliefs towards the environment to the staff and provides a framework for guiding CHEC’s ongoing environmental improvement efforts.

The policy will be reviewed by relevant parties periodically and will be displayed on notice boards in languages suitable for the nationality for the workforce.

The Environmental Policy Statement, together with the Environmental Objectives and Targets, are listed below:

1.4 The Waste Management Policy

To demonstrate the Project Team’s commitment on the continual improvement of our waste management performance, an Environmental Management Policy includes the waste management has been established. It aims to communicate CHEC’s waste management mission, vision and beliefs to the staff and public, it also provides a framework in guiding the project team the basic requirements to be achieved in waste management.

The hierarchy is illustrated below. It attempts to evaluate waste management practices and selects the best practical option since conceptually it makes sense to avoid producing a waste rather than developing extensive treatment schemes. Good planning and site management practices also help minimizing over ordering or misuse of construction materials. The overall objective is to reduce and minimize the amount of wastes generated, hence reducing the costs of waste handling and disposal.

· Summary Offences Ordinance (Cap 228)

· Other relevant regulations

1.5.2.1 The Waste Disposal Ordinance (WDO)

The Waste Disposal Ordinance (WDO) prohibits the unauthorized disposal of waste. Construction waste is not directly defined in the WDO, but is considered to fall within the category of “trade waste.” Under the WDO, wastes can only be disposed of at sites licensed by EPD.

1.5.2.2 The Waste Disposal (Chemical Waste) (General) Regulation

Under the Waste Disposal (Chemical Waste) (General) Regulation all producers of chemical wastes (including asbestos) must register with EPD and treat their wastes either utilizing on-site plant licensed by EPD, or arranging for a licensed collector to take the wastes to a licensed facility. The regulation also prescribes the storage facilities to be provided on site, including labeling and warning signs, and requires the preparation of written procedures and training to deal with emergencies such as spillages, leakages, or accidents arising from the storage of chemical wastes.

1.5.2.3 The Waste Disposal (Charges for Disposal of Construction Waste) Regulation

The current policy related to the dumping of C&D material is documented in the Works Branch Technical Circular No. 2/93, ‘Public Dumps’. Construction and demolition materials that are wholly inert, namely public fill, should not be disposed of to landfill, but taken to public filling areas, which usually form part of reclamation schemes.

Under the WDO and the Charging Regulation, wastes can only be disposed of at designated waste disposal facilities licensed by EPD. For construction work with a value of more than HK$1M, the main contractor is required to establish a billing account at EPD before transporting the construction waste to the designated waste disposal facilities (e.g. landfill, public fill etc.). The vessels for delivering construction waste to public fill reception facility would need prior approval from EPD. Breach of these regulations can lead to a fine and/or imprisonment.

1.5.2.4 The Land (Miscellaneous Provisions) Ordinance

The Land (Miscellaneous Provisions) Ordinance requires that dumping licences be obtained by individuals or companies who deliver public fill to public filling areas. The Civil Engineering & Development Department (CEDD) issues the licences under delegated powers from the Director of Lands.

1.5.2.5 The Public Health and Municipal Services Ordinance (Cap 132) - Public Cleansing and Prevention of Nuisances (Urban Council) and (Regional Council) By-Laws

The Public Cleansing and Prevention of Nuisances By-Laws provide further controls on the illegal tipping of wastes on unauthorized (unlicensed) sites.

1.5.2.6 Related Licence and Permits

The Contractor would obtain all necessary permits and licenses under these ordinances including, but not limited to:

· Registration as a Chemical Waste Producer under the Waste Disposal Ordinance (Cap 354);

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

· Registration as a Waste Producer under the Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap 354).

3 SITE SPECIFIC WASTE MANAGEMENT

3.1 Waste Policy Principles

Refer to hierarchy abovementioned in Section 1, a further explanation of the hierarchy of waste management on site is detailed below.

3.1.1 Hierarchy of Waste Management

Key to waste management is to reduce the amount of waste generated from the work site. Waste management options would be exercised in accordance with the hierarchy stipulated in the following table:

Avoidance and Minimization	Avoid and minimize waste through careful planning and design works.
Reuse	Reuse construction waste such as excavated material, used wooden plants and ferric materials.
Recovery and Recycle	Undertake on-site or off-site waste recycling.
Treatment and Disposal	Properly treat and dispose of waste in accordance with legislative requirements, guidelines and good practices.

Table 3.1: Hierarchy of Waste Management

In the context of waste reduction, environmentally responsible purchasing would involve the introduction of practices that discourage unnecessary purchases and encourage the purchase of products with reduced packaging, increased durability and materials with high recycled content, such as, recycled paper, steel and other raw construction materials.

Waste minimization is best achieved through careful planning, design and supervision. Good management practices would reduce and prevent large amount of waste generated. Raw materials would be managed from the first instance before they are ordered and delivered to the site. Good estimation and planning would minimize the amount of raw materials wasted. The generation of waste would be controlled at source.

3.2 Waste Reduction

Specific measures will be implemented to reduce the generation of waste materials, and thus minimize the amount of waste disposal to landfills. The measures will include:

· Sorting on site to recover the inert portion of C&D materials;

· Recover all metallic waste for recycling;

· Recover all cardboard and paper packaging, and properly stockpile them in dry and covered condition to prevent cross contamination;

· Use of the materials (such as formworks and hoardings) in the construction would be calculated before purchasing in order to minimize waste generation.

· Use of metal formworks and hoardings, and they would be recycled after demolition on site as far as it can before disposal.

3.3 Bentonite Slurry

The bentonite system will be set up on site to suit the site condition. It consists of storage tanks and circulation tanks to minimize contamination into site temporary drainage or substandard discharge. During concreting of piling works, the used bentonite slurry will be delivered to the residue splitter for purification and reuse wherever practicable. Residual shall be disposed of at the Tseung Kwan O Area Fill Bank. (PS Clause 25.25(1)). All disposal record for bentonite will be summarized in the monthly waste flow table.

4 WASTE MANAGEMENT PROCEDURE

The quantities of disposal C&D materials will be recorded under the barcode Trip Ticket System by using the CHIT tickets. CHIT will be presented to the landfill site as part of the system for the disposal charging scheme which had already been officially effective in January 2006. Waste transaction records could be obtained either in the waste disposal facilities right after the transaction or retrieved from the Environmental Protection Department bill statement each month.

Prior to the vehicle leaving the site, the Supervisor’s Representative will insert the date, time of departure, vehicle licence plate number, designated public filling facility/ landfill, and other information as required, and stamp the form. The Supervisor’s Representative will then retain the first strip of the form and pass the rest to CHEC’s Representative. The form will be carried on board the vehicle at all times throughout the vehicular trip.

A comprehensive register of the CHIT Tickets issued will be maintained and available for inspection by the Supervisor’s Representative upon request. The following records will be kept for monitoring of the DDF issued:-

Daily Record Summary (DRS) and the Waste Flow Table (WFT) should be completed and submitted to the Supervisor’s Representative for record. A sample of DRS and WFT, please refer to Appendix D and E respectively.

Waste Flow Table – Monthly

Record of the quantities of C&D materials generated each month will be maintained using the monthly summary Waste flow Table (WFT). CHEC will complete and submit the monthly summary WFT to the Supervisor by not later than the 15^th day of each month follows the reporting month, or if it is a General Holiday, the day following the General Holiday, or a later date as agreed by the Supervisor.

Waste Flow Table – Yearly

The estimated quantities of C&D materials to be generated each year from the site will be summarised using the yearly summary WFT. The WFT will be updated on a half-yearly basis and submit to the Project Proponent by not later than 1^st of June and December of each year, or if it is a General Holiday, the day following the General Holiday, throughout the construction period in order to account for the revised works programme and latest outturn on the quantities of C&D materials generated from the site.

These summaries shall also be made available to ETL and IEC/ENPO

Specific trip ticket and records for internal transfer of C&D materials and imported fill materials will also be kept for monitoring whatever necessary.

For recyclable materials, CHEC’s Representative will record the quantities of all the recyclable materials before removal off the Site by the recycling contractors, and include the details in the WFT for submission to the Supervisor’s Representative.

In order to ensure proper disposal of C&D materials, enhancement measures to further improve the TTS recording system, a video recording system shall be installed and disposal shall be checked against survey record. Such video recording system used to monitor the vehicular exit/ entrance of the site.

8 WASTE MONITORING AND AUDIT

The aims and objectives of waste management audit are:

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

· To ensure that the handling, storage, collection and disposal of waste arising from the demolition works comply with the relevant requirements under the Waste Disposal Ordinance and its regulations, and this WMP; and

· To encourage the reuse and recycling of materials.

The ET, with assistance from the Construction Manager, would audit the waste management practices during the weekly environmental site inspection to evaluate the overall performance of the implementation of the WMP and ensure the appropriate control measures are properly implemented. The results of the waste management audits would be reported in the monthly Environmental Monitoring and Audit reports.

In the event of any non-compliance or complaint against the provisions of this WMP, actions would be taken according to the event and Action Plan for non-compliance and complaints as shown in the following tables.
