5.0 WASTE MANAGEMENT HIERARCHY
DCVJV will adopt a surplus material management hierarchy throughout the Works. The management options can be categorized in terms of preference from an environmental viewpoint. The options considered preferable will have the least impacts and are more sustainable in the long term. The hierarchy is illustrated below. It attempts to evaluate surplus material management practices and selects the best practical option since conceptually it makes sense to avoid producing C&D material rather than developing extensive treatment schemes. Good planning and site management practices also help minimizing over ordering or misuse of concrete, mortars and cement grout. The overall objective is to reduce and minimize the amount of surplus generated, hence reducing the costs of material handling and disposal.
SITE ORGANIZATION AND STAFF DUTIES
Organization Structure
The organisation structure for waste management is outlined in Appendix A. This chart gives the overall site management in relation to waste management issues. Details on the roles and duties of staffs responsible for implementation are outlined in the below section, which identifies the key parties with specific responsibilities.

Domestic activities on site | Domestic rubbish, batteries, spent papers, sewage | - |
Sewage generated in the site offices will be diverted into public sewers and therefore there is no management issue. Portable toilets will be used for discrete and remote working areas, which are regularly replaced by our supplies.
DISPOSAL PROGRAMME
Prescribed Disposal Facilities
EPD has assigned the West New Territories (WENT) Landfill and Outlying Islands Transfer Facilities for the DCVJV to dispose of non-inert construction materials. The EPD letter to designate the prescribed disposal grounds is attached in Appendix D. DCVJV plans to go to WENT in most occasions. Among the Outlying Islands Transfer Facilities, Mui Wo Transfer Facility is the currently preferred disposal ground due to its close vicinity. Chits will be used for each disposal trip of non-inert C&D materials in WENT and the Outlying Islands Transfer Facilities.
For disposal of inert materials such as soil, rocks, boulders, alluvium and spent bentonite, DCVJV will deliver the materials to the neighbouring sites of Contracts HY/2010/02 HKBCF Reclamation and HY/2011/03 HZMB Section from Scenic Hill to HKBCF for filling purposes, as the preferred disposal grounds as stipulated in the Contract. DCVJV will liaise to the concerned parties through the Public Fill Coordination Committee that has been established under Contract No. HY/2010/02 to dispose the surplus of the inert C&D materials to Contract No. HY/2011/03 and / or Contract No. HY/2010/02 for the reuses of suitable C&D materials on their sites. For the disposal, DDF will be used for the inert materials disposal at these sites.
Under circumstances that the sites of Contract No. HY/2011/03 and Contract No. HY/2010/02 are unable to receive the inert materials for the filling purpose, DCVJV will apply to CEDD for the public fill reception facilities (PFRF) as a back-up option. The disposing materials including alluvium and bentonite will meet the PFRF requirements on material properties such as water content.
Monthly Disposal Programme
A monthly quantities of excavated materials to be generated during works has been estimated and the figures are shown in Appendix E. A table summarizing the estimated volume generated, reuse on- or offsite and the proposed disposal outlets is also presented in Appendix E. The estimated quantities, types of the C&D materials and corresponding disposal grounds will be updated monthly and indicated in the monthly programme for disposal of C&D materials, which will be reported to the SOR via submissions of monthly waste flow tables.
Internal Disposal and Control Measures to Track Movement of Materials
In cases of C&D materials generated in a site working area to be used in another area under the same Project, the types, quantities and purposes will be recorded by site agents and engineers on site and SOR will be informed of the details including the locations of work areas and transportation time to allow for the SOR’s inspection. Internal tickets exclusively for such uses will be distributed to dump truck drivers, and duly completed and signed by foremen or site agents. The format of the internal transfer ticket is shown in Appendix F. The monthly quantities of the internal disposal will be recorded in waste flow tables and be submitted to SOR.
Alternative Disposal Ground
In order to make use of C&D materials generated by the Site, DCVJV will use the best endeavours to identify recycling facilities or other construction sites where such material can be used. Where DCVJV identifies such as recycling facility or a construction sites which can be used as an alternative disposal ground, we will obtain the written approval of the SOR, who will process the request expeditiously. In support of the request for approval, the following information will be provided:
A detailed description of the alternative disposal ground, including location, lot number (where appropriate), location plan and photographs of the proposed alternative disposal grounds showing the surrounding environment and land use,
Where the alternative disposal ground is a private construction site, a letter from each of the relevant authorities, such as AFCD, LandD and PlanD, to comment on suitability of the site under their respective purview, and a letter from the Authorized Person of the development to confirm:
The C&D materials for use in the development is acceptable,
The land/pond filling in the proposed alternative disposal ground and the use of land so formed by the C&D materials are in conformity with the statutory town plan/lease conditions, and
The SOR staff are allowed to enter the alternative ground to conduct inspections where necessary.
Where the alternative disposal is a private recycling facility, it is on the recyclers’ list for C&D materials recognized by EPD, as well as a letter from the operator to confirm the SOR’s staff to enter the recycling facility to conduct inspections where necessary,
where the alternative disposal ground is a construction site of Government (other than a government contract quarry), Hong Kong Housing Authority or Mass Transit Railway Corporation, a written consent from the project office of the alternative disposal ground to use the C&D materials generated from the Site,
where the alternative disposal ground is a government contract quarry, a written consent from the Mines Division of Civil Engineering and Development Department to import the C&D materials generated from the Site,
the estimated quantity and type of C&D materials to be used/processed in the alternative disposal ground and the approximate delivery programme, together with the name, post and specimen signature of the competent person to sign disposal tickets; and
a system for transmitting disposal records from the alternative disposal ground to the SOR.
DCVJV will establish a surveillance system within the Site (as described in the following section) and at any alternative disposal grounds to check the disposal activities comply with requirements.
Disposal Grounds of Marine Sediment
The amount of marine sediments excavated from the Works shall be minimised as far as practicable e.g. only from the excavation of the foundation and the associated substructures such as the piles, pile caps and piers. In events that dredging/excavation of marine sediment are unavoidable, the Contractor shall handle/process such marine sediment in accordance with the procedures given in ETWB TCW No. 34/2002 (and the associated amendment versions).
The marine sediment to be generated from piling works will be undergone laboratory analysis during the GI stage to determine the categories in accordance with the ETWBTC No. 34/2002, Management of Dredged / Excavated Sediment. The contaminated sediment (Categories M and H) will be disposed of at the confined marine disposal facility at South of the Brothers - CMP 1. The uncontaminated sediment to be capped at East of Sha Chau – Pit IVc or Va and South of the Brothers - CMP 1, as indicated by the CEDD. DCVJV will contact the related authorities such as EPD and CEDD to request for the disposal allocations.
In cases that off-site disposal of marine sediment in Hong Kong Water required, DCVJV shall apply for the allocation of a sediment disposal site in the name of Highways Department of the HKSAR, and marine dumping permits under Dumping at Sea Ordinance (Cap. 466) (DASO) for the disposal of marine sediment at the designated disposal facilities in Hong Kong.
DCVJV will apply to the EPD for all valid permits and licences in accordance with only dispose of the marine sediment at the designated disposal facilities as directed by the Director of Environmental Protection and/or the Marine Fill Committee (MFC) unless otherwise agreed or ordered in writing by the Supervising Officer.
SITE PROCEDURES FOR TRIP TICKETS SYSTEM
A site procedure will be developed to ensure that each truck load of C&D materials leaving the site will bear a duly completed chit or disposal delivery form (DDF), and that Part of the DRS has been filled in and signed properly before its departure. The following two flow charts illustrate site procedures to handle C&D materials disposal with chits and DDFs to be implemented in the DCVJV site, and they will be modified to suit the actual site condition, after agreed with the SOR.
Where irregularity is observed or where requested by the SOR under special circumstances, DCVJV will submit to the SOR within 5 working days after the recorded date of disposal the supporting evidence such as duly

The monthly quantities of the recyclable materials removed off site will be recorded in the waste flow table for monthly submission to the SOR.
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:
sort all excavated materials and recover the inert portion of C&D materials, such as hard rock, soil and broken concrete, for reuse on the Site or, if cannot be used on the Site, disposal to designated outlets for reuse;
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;
sort all demolition debris to recover reinforcement bars, mechanical and electrical fittings, hardware and all other fittings / materials that have established recycling outlets;
tree debris will be delivered to tree debris recycler whenever available.
Material packaging (i.e. paper and cardboard) will be recovered, properly stockpiled in dry and covered environment to prevent cross contamination by other C&D materials. Attention will also be paid to avoid cross contamination during the course of paper collection for recycling. Arrangements will be made with recycling contractors to ensure that the recyclable materials sorted from the Site are handled with reasonable care. In addition, DCVJV has made agreements with certain suppliers for the collection of packaging wastes to further enhance the management of these materials on site.
CHEMICAL WASTES
DCVJV has applied to EPD for a Register of Chemical Waste Producer. Chemical wastes generated during works will be temporarily stored in Site before being delivered to designated chemical waste treatment facilility. A location is tentatively assigned for the storage of chemical wastes (Appendix H) and it will be reviewed after the commencement of work. The handling and storage of chemical wastes must comply with the requirements stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes.
Containers for the storage of chemical wastes shall –

Be disposed in the Chemical Waste Treatment Facility in Tsing Yi.
Again the monthly quantities of the chemical waste removed off site will be recorded in the waste flow table for monthly submission to the SOR.
VIDEO RECORDING SYSTEM
Requirements of Video Recording System
DCVJV will agree with the SOR on methods to provide, operate and maintain a video recording system at each vehicular exit/entrance with gate(s) installed with the following essential features to record all trucks leaving the Site. DCVJV will provide details of the video recording system including the equipment type and a layout plan to show locations where the equipment are to be installed. The video cameras used in the system shall be of high resolution, lowlight and colour type; power backup shall be provided to cater for accidental breakdown of the power supply to the system; videos captured by the system shall be recorded continuously without break except with the agreement of the Supervising Officer, or in the month during which there is no disposal of C&D materials off the Site for the entire month; videos shall be captured in a format acceptable to the Supervising Officer; the registration mark of each vehicle leaving the site shall be recorded; and the loading conditions of dump trucks including empty trucks shall be captured. The video cameras will be securely protected from being damaged or blocked.
Video Records Keeping
DCVJV will provide the software and hardware for capturing the vehicle registration mark, and the time and date for the Supervising Officer‘s immediate taking and viewing of photographs of every truck leaving the Site and viewing the recorded videos. The videos record will be kept for at least 60 days and the photographs are kept such time as instructed by the Supervising Officer. DCVJV will post sufficient notices at conspicuous positions to notify the workers, drivers and staff about the purpose of the video recording system in accordance with data protection principles set out in the Personal Data (Privacy) Ordinance.
NOTIFICATION TO TRUCK DRIVERS
The DCVJV will write to all truck drivers engaged for removal of C&D materials from the Site and draw their attention to the following particular points:
Each truck carrying C&D materials leaving the Site for a disposal ground must bear a duly completed CHIT / DDF, irrespective of the location and nature of the disposal ground; and
The C&D materials must be disposed of at the disposal grounds stipulated in the Contract or directed by the Supervising Officer or alternative disposal grounds approved by the Supervising Officer.
DCVJV has established a guiding protocol for truck drivers being engaged and give all of them a copy for their information. Where necessary, a tool box talk relating to the protocol will be given to all engaged driver. The protocol is shown in Appendix G.
Overloading Prevention
In order to prevent overloading, DCVJV will request subcontractors to deploy those dump trucks fitting with weight gauges. Marking of preset weight limit should be clearly visible on gauge for inspection. The dump truck will not be allowed to leave the site only if the reading of the weight gauge is lower than the preset level.
In addition, DCVJV will –
conduct tool box talks to new drivers or those drivers who committed overloading case, and
deploy a coordinator at the site exit to control and ensure implementing the good practices.
Surprise checks will be made by tracing the route of the dump trucks to ensure that the transport of excavated materials fully complies with the requirements of this Plan.
WASTE REDUCTION MEASURES
Reduction through Design
DCVJV accords the highest priority to managing surplus materials through reduction at source. To this end, relevant environmental aspects have been duly considered in the design and planning stage such as –
Use of precast segments and bridge piers,
Closed loop water recycling process for GI drilling as well as excavation,
Possibility of utilizing excavated granite for concrete to be used on Site.
DCVJV will also seek to use prefabricated and modular elements of precast segments, where practicable, to minimize material wastage from in-situ fabrication. The amount of surplus materials produced will be reduced by specifying accurately the volumes and dimensions of materials to be used.
Use of Timber in Temporary Works
The use of timber in temporary works construction will be avoided, reduced or minimized; and alternatively reusable steel/concrete shutters will as far as reasonably practicable be used for formwork and falsework. Metal fencing or building panels will also be used for site fencing. In the circumstances where the use of timber is unavoidable and the estimated quantities exceed 5m3, we shall submit a method statement with justifications to the Supervising Officer for agreement prior to the commencement of the relevant temporary works. In any case, the timber will be reused before being discarded as wastes.
WASTE TARGETS
Before major construction works commence, DCVJV will set waste targets to cover
Excavated materials to be sorted to recover the inert portion of C&D materials, e.g. hard rock, soil and broken concrete, for reuse on site or disposal to designed outlets,
All metallic waste to be recovered for collection by recycling contractors,
All cardboard and paper packaging (for plant, equipment and materials) to be recovered, properly stockpiled in dry and covered condition to prevent cross contamination
The use of timber quantities in temporary works.
ON-SITE SORTING OF C&D MATERIALS
C&D materials refer to both inert and non-inert surplus materials generated from construction and demolition activities. The inert portion of the C&D materials include soil, rocks, broken concrete, etc., and non-inert portion comprises of timber, paper, plastic, general refuse and the like.
All C&D materials will be sorted on Site to recover reusable and/or recyclable materials and DCVJV will assign an area for this purpose. A layout plan showing the temporary storage area is in Appendix N. All sorted and processed surplus materials will be removed to reduce temporary stockpiling on the Site. A system will be established for on-site sorting of C&D materials. It encompasses the identification of the source of generation,
estimated quantities, arrangement for on-site sorting and/or collection, temporary storage areas, frequency of collection by recycling contractors and frequency of removal off the Site, etc. The following materials will be sorted on the Site:
Metal
Timber
Paper
Plastics
Chemical waste
Materials suitable for disposal at public fill reception facilities, sorting facilities and outlying islands transfer facilities. (Disposal at the sorting facilities shall be approved by the Supervising Officer)
The materials to be disposed of at public fill reception facilities, sorting facilities and landfills/transfer facilities must comply with the respective requirement laid under Schedule 6 of the Waste Disposal (Charges for Disposal of Construction Waste) Regulation, Cap. 354.
DCVJV will provide sufficient space for temporary storage of C&D materials to facilitate collection and/or sorting on the Site. Location plan will be provided after the detail planning of site layout. Nevertheless, onsite sorting will not generate potential nuisances to the public. Except for those inert C&D materials to be reused on the Site, all other C&D materials will be removed off Site as soon as practicable to optimize the use of the on-site storage space.
To reduce concrete wastage, DCVJV will return all surplus wet concrete to batching plant, where aggregates and sand will be recovered for reuse.
SURPLUS MATERIAL MANAGEMENT AUDIT
Site inspections provide a direct means to trigger and enforce the specified environmental protection and pollution control measures. Site inspections will be undertaken weekly by the SOR and Site Agent to inspect the Site to ensure satisfactory performance on compliance with this Plan.
Weekly Site Inspections
Regular inspections on the implementation of the TTS will be under the EM&A programme which includes weekly site inspections on waste management. A sample of comprehensive checklist for the use of weekly inspection on the waste management is shown in Appendix I. This checklist will be modified according to the construction activities on site after the commencement of work. Immediately after the weekly inspection, the summary table of follow-up actions will be agreed and signed by both the Contractor’s Representative and Supervising Officer’s Representative. The Company will take prompt action to rectify the deficiencies identified and will report the status of action taken before the forthcoming weekly inspection.
Surveillance at Alternative Disposal Site
DCVJV will establish a surveillance system such as site visits at any alternative disposal grounds to check that the disposal activities comply with the requirements set out in this Construction Specification.
RECORD KEEPPING
The Environmental Officer and his team are responsible for keeping surplus material/ waste management records on site. These records include, but not limited to, the following:
relevant licences and permits, including dumping licences and registration as chemical waste producer,
approval documents by the SOR in respect of disposal locations in Mainland China and HKSAR,
records of quantities of surplus materials/ wastes generated, recycled and disposed of (including the disposal sites),
records for chits or DDFs issued out for collection, delivery and removal of wastes and surplus materials,
disposal recording register (Appendix L) of vehicular and vessel trips of transporting C&D materials and its mechanism for collection of returned forms and receipts,
method for estimation of load for surplus materials, metals, papers/cardboard or other C&D wastes
training records,
video and photographs for the loading dump truck leaving site gates.
Waste Flow Table – Monthly
A mechanism to record the quantities of surplus materials and wastes generated each month, using the Monthly Summary Waste Flow Table (WFT) in Appendix J. The monthly summary WFT will be prepared and submitted to the SOR not later than the 15th day of each month; or if it is a general holiday, the day following the General Holiday.
Summary Table – Timber Usage
A method statement will be submitted to the SOR if the use of timber for temporary works construction for one process / activity with an estimated quantity exceeding 5 m3.
A timber usage summary table (Appendix K) which contains the description, justification and the estimated quantity for every work process / activity requiring the use of timbers for temporary works construction irrespective of the quantity of timber used will be updated and submitted to the SOR together with the monthly summary WFT for monitoring and review.
20.0 STAFF TRAINING
DCVJV will provide training on surplus material management in the site-specific environmental training and its refresher training for all the Company staff and the subcontractors. The training will cover the surplus material management policy, targets, measures for waste reduction, reuse & recycling, on-site sorting of C&D materials and performance measurement on the Site.
DCVJV will develop and provide toolbox talks for the topic on on-site sorting of surplus materials to promote workers’ awareness on handling, sorting, reuse and recycling of surplus materials.
Training materials will be available for the inspection of Supervising Officer’s Representative. If further required by the Supervising Officer’s Representative, trainings organized by training institutes or organizations as considered appropriate will be arranged.
TTS PERFORMANCE MONITORING
The following items shall be included in the agenda for discussion at the monthly Site Safety and Environmental Management Committee meeting, and Site Safety and Environmental Committee meeting, or other established channels for performance monitoring as agreed by the Supervising Officer’s Representative:
review the site management plan and implementation of the TTS, and identify areas for improvement,
audit the quantity of C&D materials removed from the Site (based on the DRS and survey records) against the quantities of C&D materials delivered to the disposal ground designated in the Contract (e.g. based on EPD website) and directed or approved by the Supervising Officer,
review incidents of non-compliance and discuss the necessary follow-up actions; and
Monitor the follow-up action on defects and deficiencies identified.
MITIGATION MEASURES IN EIA
The Section 8.3 of the EIA Report gives recommendations on mitigation measures of waste management. The recommendations were extracted to form an implementation schedule particularly for waste management during construction phase and the schedule is shown in Appendix M.
