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.

1.5   Regulations and Guidelines

 

1.5.1    General

 

Various types of wastes would be generated during the course of the Project and each waste type requires different approach for management and disposal as stipulated in the waste legislation and guidelines. The relevant statutory and non-statutory requirements regarding waste management are summarized in the sections below.

 

1.5.2    Statutory Requirements

 

The following legislation relates to the handling, treatment and disposal of wastes in Hong Kong, and would be observed with regard to all wastes generated and requiring disposal, where applicable:

 

·         The Waste Disposal Ordinance (Cap 354)

·         The Waste Disposal (Chemical Waste) (General) Regulation (Cap 354)

·         The Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap 354)

·         The Land (Miscellaneous Provisions) Ordinance (Cap 28)

·         The Dumping at Sea Ordinance (Cap 466)

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

·         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.

 

4.1   Acceptance Criteria for the Government Disposal Facilities

4.2   Procedures of the Trip Ticket System

 

China Harbour Engineering Co., Ltd. (CHEC) will implement a Trip Ticket System (TTS) to track the disposal of C&D materials. Under the TTS, each truck carrying C&D materials leaving the Site for a disposal ground will bear a duly completed and stamped CHIT Tickets. The C&D materials must be disposed of at the disposal grounds as stipulated in the CHIT Tickets.

 

The Trip Ticket System will be executed according to the following procedures:

 

·         The General Foremen / Foremen will arrange the C&D waste to be sorted on site.  He will also check the total actual amount of cumulated C&D waste after the completion of the particular works in the working area.

·         If the sorted C&D waste is less than 1/3 of truckload, then the C&D waste will be transferred to the temporary holding area in CHEC’s works area for temporary stockpiling.

·         The C&D waste will be sorted and stored separately in different storage areas.

·         Non-inert C&D waste will be stored in storage tanks properly covered with tarpaulin sheeting in the temporary holding area.  Inert C&D materials will be stored on the ground properly covered with tarpaulin sheeting in the temporary holding area.  Larvicidal oil or larvicide will be applied onto the stored C&D waste, if necessary.

·         For every 7 days or one truckload collected, the stored non-inert C&D waste in the temporary holding area will be transferred to the designated landfills.

·         For every 14 days or one truckload collected, the stored inert C&D waste in the temporary holding area will be transferred to the designated fill banks.

·         If the sorted C&D waste is more than 1/3 of truckload, then the Foreman will arrange disposal of the C&D waste to designated fill banks / landfills.

·         For each truckload of C&D materials leaving the working area / temporary holding area to the designated fill banks / landfills, the truck driver must bear a duly completed and signed CHIT.

·         The General Foreman / Foremen will check, record with photo and ensure the dump truck is not overloaded by the electronic dump truck self-scale and the materials / waste are properly covered, a several weight buffer is allowed to prevent overloading.

·         The General Foreman / Foremen will fill in and sign the Part 1 of the Daily Record Summary (Appendix D) and submit to the Supervisor’s supervisory staff.

·         The Supervisor’s supervisory staff will cross check the dump truck loading and coverage and sign the Part 1 of the Daily Record Summary (Appendix D) for endorsement, and a duplicate and a copy of Daily Record Summary will give to the Supervisor’s supervisory before departure of the truck.

·         After that, the General Foreman / Foremen will give the duly completed and signed CHIT to the truck driver.

·         The truck will proceed to the disposal ground as stipulated in the CHIT.  The truck driver will present the CHIT to the reception facility operator.  If the C&D waste accords with the acceptance criteria, disposal of the C&D waste will be permitted and the facility operator will give the truck driver a transaction receipt and the CHIT.

·         The truck driver will present the CHIT at the in-weighbridge of the disposal facilities.  If the vehicle load is accepted, the CHIT is deemed to be used and the in-weight would be recorded on the “Transaction Record Slip”.

·         If the truck driver is instructed by the reception facility operator to go to the sorting facility.  The driver will need to return back to the site and report to the General Foreman / Foremen.  No driver is allowed to go to sorting facility.

·         The truck driver will then return the transaction receipt and the stamped CHIT to CHEC as soon as possible.

·         CHEC will maintain a daily record disposal of C&D materials from the Site including details of the C&D waste, the truck number, departure time, etc, and notify the Supervisor’s Representative in case any discrepancy is noted.

·         For disposal at government disposal facilities, CHEC will check the information recorded in the Daily Record Summary against the disposal records in Civil Engineering and Development Department’s website (http:www.cedd.gov.hk/eng/services/tripticket/index.html) or Environmental Protection Department’s website (http://www.epd.gov.hk/epd/misc/cdm/trip.htm) and complete Part 2 of the DRS for submission to the Supervisor’s Representative within 3 working days after the day of disposal.

·         Where an irregularity is observed or when requested by the Supervisor’s Representative under special circumstances (e.g. a CHIT has been issued but there is no disposal record at the designated disposal facilities), CHEC will submit to the Supervisor’s Representative within 5 working days after the recorded date of disposal the supporting evidence such as duly stamped CHIT and/or the transaction receipt (where relevant) to confirm proper completion of the delivery trips in question, or within 2 working days after the Supervisor’s Representative has requested for such evidence, whichever is later.  A fax copy of the CHIT and transaction receipt is acceptable, unless otherwise directed by the Supervisor’s Representative.  CHEC will maintain all records on the CHIT for at least one year or other period as may be directed by the Supervisor’s Representative.

 

4.3   Measures to be implemented during transportation of wastes to avoid leakage of wastes on public areas

 

·         All of the dump trucks used would be equipped with mechanical covers in which maintained in a good condition.

·         In order to minimize the leaking of material from the dump trucks, no material should be stored higher than the trail board.

·         Deposited silt and wastes on all dump trucks’ wheels and bodies should be properly washed off by wheel washing facilities before leaving the constructions sites.

·         CHEC will provide wheel washing facilities on site at the site entrance.

 

4.4   Disposal of C&D Materials to Alternative Disposal Ground(s)

 

Where CHEC has identified a project that can be an alternative disposal ground, CHEC will provide a detailed description of the alternative disposal ground, including location, lot number (where appropriate) and location plan(s) to the Supervisor to request for his written approval.

 

Where the alternative disposal ground is a private construction project, CHEC will submit a letter from the Authorized Person of the development (as defined under the Building Ordinance) to confirm that:

 

·         The C&D materials for use in the development is acceptable;

·         The use of land so formed by the C&D materials is in conformity with the statutory town plan/ lease conditions;

·         The Supervisor’s Representative are allowed to enter the alternative ground to conduct inspection where necessary; and

·         The estimated quantity and type of C&D materials to be used in the construction works and the approximate delivery programme, together with the name, post and specimen signature of the competent person to sign the DDF/ internal trip ticket stipulated in G.S. Clause 25.25(6)(a)(ii).

 

Where the alternative disposal ground is a private land but not a construction site, CHEC will submit a letter from the relevant authorities, such as the Lands Department and the Planning Department, to confirm that the suitability of the alternative disposal ground in receiving the proposed amount of C&D materials for use, and a written consent from the landowner.

 

Where the alternative disposal ground is a government project, CHEC will submit written consent from the project office of the alternative disposal ground to use the C&D materials generated from the Site, and to confirm the estimated quantity and type of C&D materials required and the approximate delivery programme.

 

A system for transmitting disposal records from the alternative disposal ground will be submitted to the Supervisor’s Representative for approval before disposal to the alternative ground starts.

 

4.5   Chemical Waste/ Hazardous Waste Handling and Disposal

 

Chemical waste that is produced, as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, will be handled in accordance with the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes as follows:

4.8   Use of Timber

 

CHEC aims to avoid, reduce or minimize the use of timber in temporary construction activities. Where the use of timber is unavoidable for temporary works construction processes or activities with an estimated quantity of greater than 5m3, CHEC will submit a method statement to the ER for agreement before starting the relevant temporary works. The method statement will include the justifications for the use and the measures taken to minimize the use of timber.

 

The summary table of timber usage will be updated and submitted to the ER for monitoring and review by not later than the 15th day of each month or, if it is a general holiday, the day following the general holiday, or a day agreed upon with the ER.

 

4.9   Handling of Recyclables

 

Before starting the transportation of recyclable materials off site to recycling facilities,

CHEC will meet with recycling contractors to establish a suitable system for collecting recyclable materials with care.
