1 INTRODUCTION

1.1 Background

1.1.1 This Waste Management Plan (WMP) has been prepared to fulfil Condition 2.8 of the Environmental Permit (EP No. EP-121/2002) with respect to the demolition works of the Project – “Demolition of Kwai Chung Incineration Plant”. The major scope of the demolition works of the Project is to remove all ACM/DCM in chimney and superstructures before commencement of the demolition works. The decontamination works of the Project will be carried out after completion of the demolition works of the Project.

1.1.2 This WMP does not cover the decontamination works to be carried out for the Kwai Chung Incineration Plant (KCIP). The corresponding WMP for the decontamination works will be submitted under a separate cover for ground decontamination works.

1.1.3 As there have been ongoing discussions between EPD and CEDD on proposals for treatment and disposal of dioxin containing materials (“DCM”) within the KCIP Chimney, these parts of the WMP have been put on hold until an agreement is reached between the two departments. Subject to agreement with EPD, the treatment method and disposal of DCM for the KCIP Chimney will be finalized.

1.1.4 This WMP has therefore focused on and finalized the rest of waste management aspects with respect to waste generation, treatment and disposal for this Project other than DCM (and ACM to avoid cross-contamination) within the KCIP Chimney in order to facilitate early approval by part so that other parts of the Project can proceed independently.

1.1.5 WMP versions 1.1 and 2.2 were certified by ET and verified by IEC and submitted to EPD on 29 November 2007 and 9 April 2008 respectively for approval.

1.2 Scope of Demolition Works of the Project

1.2.1 The demolition works of the Project with boundary as shown in Figure 1-1 is summarised in Table 1.1.

Table 1‑1 Structures to be Demolished at KCIP

^Building	^{Brief Description}
KCIP Chimney	Reinforced concrete construction of diameter 6m – 12m and 150m high. Internal metal flues and platforms
KCIP Buildings	High, single storey steel frame, with weather cladding, pre-cast concrete slab, reinforced concrete partitions, corrugated metal sheet external wall and roof. The overall size is approximately 83m x 92m on plan.
Weigh Bridge Office No. 2	Single Storey. Approximately 4m x 13m on plan.
Site Office/ Storage Buildings	Two storey high prefabricated building. Approximately 40m x 7.5m on plan.

1.2.2 The demolition works of the Project also includes the removal of asbestos containing materials (“ACM”) and dioxin/ furan contaminated materials (“DCM”) prior to demolition of the relevant structures.

1.3 Construction Programme

1.3.1 The Contract for the Project was awarded on 26 October 2007 and contractually commenced on 31 Oct 2007.

2 WASTE MANAGEMENT POLICY

2.1 General Principles

2.1.1 The principles of waste management to be adopted in this Project will be in line with the latest Government policy on environmental management.

2.2 Hierarchy of Waste Management

2.2.1 The various waste management options will be categorised in terms of preference from an environmental viewpoint. The options considered to be more preferable have the least impacts and are more sustainable in the longer term. Hence, the hierarchy of waste management is as follows in descending order:

Table 2‑1 Hierarchy of Waste Management

Avoidance and Minimization	Avoid and minimize generation of C&D materials through careful planning and design of works
Reuse	Reuse inert portion of the C&D materials generated.
Recovery and Recycle	Undertake on-site and off-site waste recycling
Treatment and Disposal	Properly treat and dispose of waste in accordance with legislative requirements, guidelines and good practices.

2.2.2 This hierarchy will be used to evaluate waste management options, thus allowing maximum waste reduction. Waste reduction measures will be introduced at the planning and detailed design stage and carried through the construction activities, whenever possible, by careful purchasing control, reuse of formworks and good site management.

4 WASTE GENERATION AND DISPOSAL

4.1 Waste Overview

4.1.1 The following types of waste would be generated from the demolition activities under this contract:

· General refuse

· Inert Construction and Demolition (C&D) Material

· Non-inert C&D Material

· Recyclables

· Asbestos Containing Materials (ACM)

· Dioxin/Furan Contaminated Materials (DCM)

· Chemical waste

4.1.2 The estimated quantity of waste arising from different activity & work areas, and the disposal sites for the wastes generated from the project are provides in the following sections. The estimated period of waste generation to landfill site is from December 2007 to August 2009 excluded the period of land decontamination works. The waste disposal schedule to landfill site is shown in Appendix G1.

Table 4‑1 Summary of Waste Disposal

Waste Type	Examples / Classification	Disposal Site
General Refuse	• Packaging waste • Office waste • Putrescible wastes • Vegetation	• SENT Landfill by vehicles
Inert C&D material	• Broken concrete • Brick • Aggregate	• Public Fill at Tuen Mun Area 38 Fill Bank
Non-inert C&D material	• Wood • Bamboo	• SENT Landfill
Recyclables	• Metal • Paper • Plastic	• Recycling collectors
Asbestos Containing Material (ACM)	• Type 1 • Type 2 • Type 3 •	• Disposal of at SENT Landfill by licensed collector • Abatement and disposal ACM within Chimney not covered in this WMP and will be submitted in next version.
Dioxin/Furan Contaminated Material (DCM)	• Ash bunker • Chimney flues	• Disposal of at SENT / WENT Landfill by licensed collector (disposal to CWTC will only be a fallback solution as per EP No. 121/2002) • Treatment and disposal of DCM within Chimney not covered in this WMP and will be submitted in next version.
Chemical Waste	• Spent lubricant oil • Surplus paint • Spent diesel	• To be collected by licensed waste collector

4.2 General Refuse & Non-Inert C&D Material

Source of Wastes

4.2.1 General refuse will be generated largely by food service activities for on‑site staff, from office work and certain aspects of the construction works, and will include food wastes, unrecyclable waste etc.

Estimated Quantities and Timing for Generation

4.2.2 It is estimated that the general refuse and non-inert C&D material arising will be about 50m³ per month exclude the period of land decontamination works. Although the size of the site office establishment will vary at different stages of the demolition works, thus be observed that the relative contribution to the general wastes from site staff, which will be generated throughout the whole contract period, will be small in terms of the overall wastes arising. The tentative programme of the non-inert C&D material generation would be from December 2007 to August 2009 exclude the period of land decontamination works.

Control Measures

4.2.3 Office waste will be reduced through reduce use of paper and minimize the waste generation.

4.2.4 General refuse including food wastes, such as lunch boxes, and domestic wastes generated on-site will be stored in enclosed bins or compaction units separated from construction and chemical wastes.

On-Site Handling or Storage

4.2.5 Putrescible wastes, such as lunch box, and domestic wastes generated on-site will be stored in enclosed bins or compaction units separate from C&D and chemical wastes. Location of temporary storage of general refuse is indication in Figure 4-1.

Disposal Arrangement

4.2.6 A reputable waste collector will be employed by the Contractor to remove general refuse and to be disposed of at landfill site, separately from C&D material and chemical wastes, preferably daily to minimise odour, pest and litter impacts. The burning of refuse on construction sites is prohibited by law.

4.2.7 Waste disposal records will be obtained from the appropriate authorities and collection of general refuse and general site housekeeping will be carried out in accordance with the Waste Disposal Ordinance (Cap. 354), Waste Disposal (Chemical Waste) (General) Regulation (Cap. 354) and the Government Land (Miscellaneous Provisions) Ordinance (Cap. 28).

4.3 Inert C&D Materials & Recyclables

Source of Wastes

4.3.1 Due to the nature of the works, C&D materials, other than material mentioned at paragraph 4.2, will also be generated under the contract. The types of C&D materials include the following:

· Inert C&D materials (including rock, broken concrete, etc); and

· Recyclables non-inert materials such as metal components, plastic & paper.

4.3.2 C&D material comprises materials broken up during demolition, including concrete and structural steel. Alternatively there are materials which are surplus to requirements for the demolition process and materials which have been used and discarded. The bulk of the C&D material will come from the buildings and other related structures (e.g. chimney) which are to be demolished. C&D material may comprise different types of materials.

4.3.3 C&D materials are typically generated simultaneously in mixed form and the individual waste materials may be altered (e.g. painted). The final actual volume and composition of C&D waste requiring disposal to public filling area following the demolition at KCIP will be dependent on the demolition procedure and material recovery practices employed.

Estimated Quantities and Timing for Generation

4.3.4 It is estimated that the total C&D material arising will be about 9,000m³ which mainly consist of broken concrete. Meanwhile, a small portion of recyclables (approx. 180m³) which would be collected by the recycling collectors would also be generated from the demolition works. The estimated quantities of recyclables would be:

· Steel bars: total 1,900 tonne;

· Plastic: 100kg per month; and

· Paper: 100kg per month.

4.3.5 The tentative programme of C&D materials generation would be from the 12^th month to the 24^th month covering the period from the commencement of the contract works to the completion of the demolition works.

Control Measures

4.3.6 To reduce / minimize the generation of C&D materials, materials resulted from the demolition works will be sorted properly to recover the inert portions for reuse on site or disposal to designated outlets.

4.3.7 Sorting of inert and non-inert portions of demolition materials will be carried out at the source site to avoid double handling and loss of materials due to transportation. In case the site condition is inapplicable for sorting, it will be carried out at the designated storage area. Reusable / recycling materials of both the inert and non-inert portion will be further recovered for on-site reuse or collection by the recycling contractors.

4.3.8 Demolition materials will be segregated from other wastes to avoid contamination thereby ensuring acceptability at public filling areas and avoiding the need for disposal at landfill.

On-Site Handling or Storage

4.3.9 Due to the large volumes of (non-contaminated) C&D material generated from the demolition works, it is important that selective demolition and on-site sorting as described below will be incorporated into the tender documents for implementation by the Contractor.

Selective Demolition

4.3.10 “Selective Demolition” involves demolition and removal of wastes of the same category one at a time. In general, domestic wastes such as furniture, household appliances; metal components such as window frames, pipes; timber components such as doors, wooden floors; and other wastes such as tiles, asphalt materials, ceramic products will be removed first. The building demolition will begin after all the above non-structural materials have been stripped and removed. To avoid mixing the non-recyclable bricks with the broken concrete, the demolition sequence will be planned in such a way that brick walls are demolished first and stockpiled separately before the demolition of structural members.

On-site Sorting

4.3.11 C&D material will be removed from site as soon as practicable to avoid adverse environmental impacts due to on-site storage of the material. It will be sorted/separated at the construction site as far as practicable into two main types: inert (including soil, rock, concrete, brick, aggregates and asphalt) and non-inert (wood, paper, general garbage and other inorganic).

4.3.12 All inert C&D materials from demolition such as the rock and broken concrete will be disposed off site to the designated Public fill reception Facilities (PFRF) whilst the non-inert portion excluding all reusable / recyclables material, is classified as C&D waste which will require to be disposed of at the WENT/ SENT Landfill Site or other areas as designated by EPD. For inert C&D materials to be disposed of at designated PFRF, the Contractor will ensure that the C&D materials be broken down on site to less than 250mm so as to facilitate its reuse in reclamation or earth filling projects.

4.3.13 C&D material will be transported by barge. The C&D material generated from the demolition works will be loaded on barge immediately and be transported offsite as soon as it fills the capacity. Location of temporary storage of C&D material is indicated in Figure 4-1.

4.3.14 Designated areas for segregation and temporary storage of reusable and recyclable materials are identified. The Contractor will recycle as much of the C&D material as possible on‑site. Different areas of the work site will be designated for such segregation and storage wherever site conditions permit.

Recyclables

4.3.15 To encourage environmental awareness and to reduce waste by reducing the number of photocopies to a minimum and by copying on both sides of paper for internal documents and external documents where appropriate. Recycling bins for paper and plastic bottle will be provided in site office to facilitate the recycling. Waste paper and plastic bottle will be stored in containers clearly marked as recyclable or waste. Location of temporary storage of recyclable is indicated in Figure 4-1 of Appendix A.

Disposal Arrangement

4.3.16 Environment, Transport and Works Bureau Technical Circular (Works) No. 31/2004 – Trip-ticket System for Disposal of Construction and Demolition Materials promulgates the policy to implement a trip-ticket system in Public Works Programme (PWP) contracts for the proper disposal of C&D material at public filling facilities or landfills. A trip-ticket system should be implemented for this Project in accordance with ETWB TC(W) No. 31/2004 as per the recommendation of the approved EIA Report and the conditions of the Environmental Permit therefore overrule the exemption quantity of 50,000 m³ specified in ETWB TC(W) No. 31/2004.

4.3.17 All inert C&D material for disposal shall be transported by barge to the public fill area or other areas as designated by EPD. Vessel chits forms should be used for C&D material disposal of at public fill area by barge.

4.3.18 The transportation route for disposal of C&D material is indication in Figure 4-2 of Appendix A.

4.4 Asbestos Containing Materials (ACM)

Source of Wastes

4.4.1 ACM is classified as Part A waste under the Waste Disposal (Chemical Waste) (General) Regulation. An Asbestos Investigation Report (AIR) and Asbestos Abatement Plan (AAP) have been prepared by Registered Asbestos Consultants (EPD register 1014 and 1019) based on thorough site investigations under the Air Pollution Control Ordinance (APCO).

Estimated Quantities and Timing for Generation

4.4.2 There will be up to 1,500m³ of asbestos waste mainly in the form of “Galbestos” (galvanised metal sheeting which forms the outer cladding on the main building). The galvanised metal cladding is coated with asbestos containing material paint and will be disposed of in line with the requirements of the APCO. Three types of ACM were identified at the EIA stage. The quantities of each type of ACM identified are summarized in Table 4-2.

Table 4‑2 Estimated Quantity of ACM

	Total Volume = Type 1 + Type 2 + Type 3	Grand Total	1,499.1

*The abatement, treatment and disposal of any ACM within the KCIP Chimney shall be subject to later agreement with EPD and to be covered in a separate WMP for Chimney.

^# There are the same estimation between onsite survey and estimated in the EIA stage and approved AAP. The proposed packing method is following the approved AAP section 5.1.3. The actual bulk volume of weather cladding depends on the shape and the Contractor will try the best to reduce the waste volume if applicable.

4.4.3 The tentative programme of the ACM generation would be from June 2008 to December 2008.

On-site Handling and Storage

4.4.4 All ACM will be removed prior to commencement of demolition works. Other than ACM located in chimney, ACM are located separately from DCM. Thus asbestos removal works will not be disturbed and cross contamination with DCM Details on the method statements, work sequence and procedure with regard to removal of ACM are included in Appendix D.

Package of Asbestos Wastes:

· Type 1 asbestos wastes (approximately 3m³ of bulk material plus 13,404m² of floor tile and claddings. It is estimated that the thickness of floor tiles is 2mm and removal of weather cladding will follow the approved AAP section 5.1.3, i.e. a total of 1,403.8m³ of type 1 asbestos waste including ACM waste generated during decontamination. Refers to Table 4-2 for details) (bonded asbestos wastes, other than blue or brown asbestos in good condition) will be packed with 2 individual layers of strong transparent plastic sheets of not less than 0.15 mm thickness and completely sealed with adhesive tapes. Type 1 waste will be packed in suitable sizes for easy handling. The height of each package will be around 1m.

· Type 2 asbestos wastes (approximately 52.3m³ of bulk material including ACM waste generated during decontamination, refers to Table 4-2 for details) (any waste containing loose asbestos fibres (other than blue or brown asbestos)) must be contained, as soon as it is produced, in strong bags made from plastic or other containers approved by EPD. The bags should be goose-neck sealed by means of adhesive tapes. A bag filled with asbestos waste should be placed inside another plastic bag to provide additional protection. The colour of the inner bag should be white while the outer bag should be transparent to facilitate visual inspection.

· The handling of Type 3 asbestos wastes (approximately 43m³ of bulk material including ACM waste generated during decontamination, refers to Table 4-2 for details) (all blue asbestos (crocidolite) and brown asbestos (amosite), whether in good condition or not, or any articles contaminated by blue or brown asbestos) should be similar to that of Type 2 except that the colour of the inner bags should be orange.

Storage of Asbestos Wastes

4.4.5 All asbestos waste will be stored properly in a secure place isolated from other substances so as to prevent any possible release of asbestos fibres into the atmosphere and contamination of other substances. Type 1 asbestos waste will not be stored together with Types 2 and 3 asbestos wastes so as to avoid damage to the plastic bags of Type 2 or 3 asbestos waste, unless the bags are packed in boxes or drums for additional protection. Bagged asbestos waste will not be stacked more than 3 bags high in order to avoid damage to the bottom bag. The storage area will be isolated from other working areas and bear warning panels to alert people of the presence of asbestos waste.

4.4.6 Location of temporary storage area of asbestos wastes is indicated in Figure 4-1.

Disposal Arrangement

4.4.7 Disposal of asbestos wastes will not commence before a designated notification has been given to EPD and confirmed. Before being transported for disposal, all the asbestos waste produced will be stored in a temporary storage area which complies with the requirements of Section 7 of the Code of Practice on the Handling, Transportation and Disposal of Asbestos Waste.

4.4.8 All asbestos wastes for disposal shall be transported by an asbestos waste collector - General Central Engineering Limited, licensed by EPD and in a designated barge equipped as stated in the Code of Practice and to be disposed of at the SENT Landfill Site or other areas as designated by EPD. For waste transportation arrangement for the delivery to and deposition at SENT Landfill Site, the Contractor will use CEDD’s pier at TKO Area 137 for unloading the materials to truck and then deliver to EPD’s landfill site. The self-explanatory letter of CEDD is shown in Appendix E. The asbestos wastes would be temporarily stored in 39 containers to be transported to the barge. It is estimated that each barge could accommodate 8 nos. containers and therefore totally 5 barge trips for the disposal of the waste to the landfill from June 2008 to December 2008 would be required.

4.4.9 Pursuant to S74(3) of the APCO, the proposed amendment to use marine vessel for transportation of asbestos waste was approved by EPD [Ref.: (10) in EPAC/A/15/000/918 Pt.VI dated 29 August 2007] on the condition that the marine vessels will be the approved ones listed in the list of licensed chemical waste collectors issued by EPD. Transportation route for disposal of ACM waste is indicated in Figure 4-2 and the generic method statement of ACM removal is attached in Appendix D.

4.5 Dioxin / Furan Contaminated Wastes

Source of Wastes

4.5.1 According to Section 4.7.26 of the approved EIA Report (AEIAR-049/2002), ash waste containing a considerable amount of dioxin and in its untreated state would be classified as a chemical waste under the Waste Disposal (Chemical Waste) (General) Regulation.

4.5.2 Dioxin contaminated ash on the walls and floor near the ash bunker will be collected and stabilized with cement to meet landfill disposal criteria of EPD, e.g. TCLP tests as per Section 4.7.32 of the approved EIA Report (AEIAR-049/2002). The stabilized ash/ sediment will then be sealed in polythene-lined steel drums for landfill disposal.

4.5.3 Treatment and disposal of ash from the chimney of the KCIP shall be subject to later agreement with EPD and be documented in a separate WMP for approval.

4.5.4 Regarding the quantities and level of contamination of DCM in ash bunker and the KCIP chimney, please refer to the following section.

Estimated Quantities and Timing for Generation

4.5.5 The estimated quantity of dioxin/furans contaminated waste after detailed site investigation works carried out subsequent to the EIA stage is as follows:

Ø Ash and sediment in the area of the Ash bunker: 20m³[Cement-stabilisation on-site, followed by disposal to landfill (disposal to CWTC will only be a fallback solution as per EP No. 121/2002)]

Ø Ash in the chimney flue: 7m³(to be agreed with EPD in a separate WMP)

Ø Chimney flue sections: 1,100m³(to be agreed with EPD in separate WMP)

Level of Contamination

Ash Bunker

4.5.6 The laboratory analysis results presented Table 4-3 below has verified the findings of the EIA Report with respect to dioxin contamination around the ash bunker. Amongst the 12 samples collected around the ash bunker, PCDDs/PCDFs were detected in 11 samples, and 4 samples were found to have TEQ exceeding the USEPA criterion and EP no. EP-121/2002 Clause 2.13 requirements of 1ppb TEQ. The sampling location is given Figure 4-3 of Appendix A.

Table 4‑3 PCDDs/ PCDFs Analysis Results for Samples Collected at the Ash Bunker

Sample ID	Type of Sample	Location	Total TEQ (ppb)*
D1	Ash	Surface sample from wall of ash bunker at 5m above ground level	4.6184
D2	Ash	Surface sample from wall of ash bunker at 7m above ground level	0.32281
D3	Ash	Surface sample from wall of ash bunker at 5m above ground level	3.06332
D4	Ash	Surface sample from wall of ash bunker at 7m above ground level	2.77459
D5	Ash	Surface sample from floor at 5m away from the ash bunker	0.02491
D6	Ash	Surface sample from floor at 5m away from the ash bunker	0.00301
D7	Sediment	Sediment sample from bottom of ash bunker	0.20995
D8	Sediment	Sediment sample from bottom of ash bunker	0.41922
D9	Water	Water sample taken from ash bunker	0
D10	Water	Water sample taken from ash bunker	0.00017
D11	Ash	Surface sample from floor at 5m away from the ash bunker	2.73043
D12	Ash	Surface sample from floor at 5m away from the ash bunker	0.01233

* Limited level = 1 part per billion (ppb)

4.5.7 Dioxin was found in ash deposits in the ash/sediment of the Ash Bunkers, the Main Hall Ash Bunker and wall above Ash Bunker of the KCIP site. As indicated in the approved EIA Report, remedial action is required to clean up these materials prior to demolition. The decontaminated structures, including the ash bunker, wall and floor would be dismantled as part of the overall demolition programme. The dismantled structures should be disposed of as Construction and Demolition (C&D) Material.

4.5.8 Based on the laboratory testing results, it is considered that the ash material retained on the surface of the wall (D1, D3 & D4) and north side of upper floor beside the ash bunker (D11) are dioxin-contaminated (i.e. >1ppb TEQ with the range of 2.7 – 4.6 ppb TEQ). Furthermore, the surface of the wall (D2), the ground floor nearby the ash bunker (D5, D6 & D12), accumulated water (D9 & D10) and sediment (D7 & D8) inside the ash bunker were found below 1ppb TEQ. The total quantity of ash and sediment material to be handled is estimated to be in the order of 20m³ (i.e., 13m³ of sediment at the bottom of the ash bunker and 7m³ of ash on surface of wall and floor around the bunker).

Timing for generation

4.5.9 The tentative programme for DCM generation around the ash bunker would be tentatively from August 2008 to December 2008.

On-Site Remediation Works

Ash Bunker (20 m³ of ash and sediment in the area of the ash bunker)

4.5.10 To prevent cross-contamination with the low concentration DCM, the treatment sequence is firstly for accumulated water in ash bunker; secondly for sediment and wall ash to be treated at the last.

4.5.11 There is about 2,000m³ water accumulated inside the ash bunker. From the laboratory results of the water samples (D9 & D10), it was found that the dioxin concentration is much lower than the criteria. To prevent extract the sediment prior to discharge, water will be pumped into the sediment tank with 5mm water filter, reassurance test will be carried out prior to discharge.

4.5.12 As the dioxin level of sediment (D7 & D8) and ground floor (D5, D6 & D12) were below 1ppb TEQ, sediment will be excavated and ground floor will be HEPA vacuumed cleaned. The collected sediment and ash will be mixed with 10% cement for solidification within the full containment. The treated sediment floor ash shall meet the TCLP test before be sealed into steel drums lined with plastic sheeting prior to disposal at designated area in landfill. In case of failure in the reassurance TCLP test, the mixing percentage will be increased to ensure passing the TCLP requirement. It is estimated that 13m³ ash and sediment to be collected and 14.3m³ treated ash and sediment to be disposed of.

4.5.13 The remediation strategies for contaminated material will be adopted where the level of dioxin contaminants exceeded the USEPA criterion of 1ppb. D2 is located on the wall of the ash bunker which closed to D1, as prudent approach to prevent cross-contamination during decontamination works, D2 will be treated together with D1, D3, D4 and D11. For the sampling locations vicinity to D1, D2, D3, D4 and D11, ash/rubble will be HEPA vacuumed and scrabbled. Cement stabilization/solidification will be carried out for the ash/rubble to meet landfill disposal criteria (TCLP test) of EPD, 1ppb TEQ and specified in Condition 2.13, Part C of the EP. Pilot test will be carried out first to obtain the reasonable cement ratio for the ash/rubble. The confirmation test will be carried out. The flow diagram of cement solidification is given Appendix F1. It is estimated that 7m³ ash will be collected and estimated that 14m³ treated wall ash will be disposed of subjected to cement ratio obtained from pilot test.

Pilot Test for Dioxin/Furan Contaminated Soil/Ash Solidification

4.5.14 The ratio of contaminants / cement mixture must be predetermined as the effectiveness of the solidification process depends upon a number of factors including the concentration of contaminants, contaminants quality, moisture content, and quality of cement.

4.5.15 Given the time factor and as a conservative approach, the pilot test for the dioxin contaminated ash/rubble (i.e. ash collected near D1, D2, D3, D4 and D11) will commence with cement ratio of 50% to ensure passing the TCLP requirement of 1ppb TEQ. The ratio of cement will be increased in case of failed in the test to achieve the landfill disposal criteria (TCLP test) of 1ppb TEQ. The flow diagram of cement solidification is given Appendix F1. In accordance with the EP Condition 2.14, disposal at the Chemical Waste Treatment Centre, Tsing Yi, will be considered as a fall back option if the pilot test criteria cannot be met.

4.5.16 It is estimated that the cement mixing ratio of 300% could be achieved the disposal criteria, otherwise fall back option as stated in EP Condition 2.14 will be considered. All collected ash near D1, D2, D3, D4 and D11 will be sealed into steel drums lined with plastic sheeting prior to disposal at the Tsing Yi Chemical Waste Treatment Centre. Designated barge will deliver to the Chemical Waste Treatment Centre.

4.5.17 After granted the disposal license from EPD, the Contractor will carry out the reassurance test to satisfy the disposal licence requirements, if any. The ratio of cement to soil/ash will then be selected based on the results of the TCLP tests. The methodology of TCLP is given in Appendix F2.

On-site Handling and Storage

4.5.18 DCM decontamination works will be conducted within a full containment. Ash contaminated with dioxin will be treated by solidification / stabilisation with cement, and the treated ash shall meet the TCLP test before it is sealed into steel drums lined with plastic sheeting prior to disposal at designated areas in landfill. According to “A Guide to the Registration of Chemical Waste Producers” issued by the EPD, ash generated from incineration of wastes is classified as chemical waste.

4.5.19 As a prudent approach, all wastes generated from the decontamination and removal works will be considered as contaminated waste and will be properly handled and disposed of. Other waste such as polythene wrapping sheets, waste generated from the dismantlement of the containment and decontamination units, and cloth used in wet wrapping, etc. will also be classified as contaminated waste. It is estimated that 3m³ used materials will be generated and disposed of.

4.5.20 The storage, handling, transport and disposal of chemical waste will be in accordance with the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes issued by EPD.

4.5.21 A total of 31.3m³ of treated DCM and contaminated materials, subjected to cement ratio obtained from pilot test, will be generated from the decontamination works of ash bunker and will be either directly sealed in drums or be remediated followed by sealing in drums. These drums will be temporarily stored within the enclosed material storage building, prior to landfill disposal. Location of the temporary storage area is indicated in Figure 4-1.

Disposal Arrangement

4.5.22 All contaminated residual ash removed from the ash bunker will be solidified with cement and sent to designated landfill site for disposal after passing the TCLP test.

4.5.23 This waste stream will be disposed of at a designated landfill site under the surveillance of trip ticket system. A permit will be obtained from EPD prior to disposal.

4.5.24 All DCM wastes for disposal will be transported by licensed chemical waste collector approved by EPD and in a designated barge equipped as stated in the Code of Practice and to be disposed of. Barge will berth at the barging facilities of CEDD Mines Division at Tsuen Kwan O Area 137 and waste will be delivered to designated landfill by trucks or other disposal outlets as directed by the EPD / Engineer’s Representative. Transportation route for disposal of DCM waste is indication in Figure 4-2.

4.6 Chemical Wastes

Source of Wastes

4.6.1 The chemical wastes generated from the demolition works will primarily arise from the maintenance of plant and equipment. These wastes include spent lubricant oil, surplus paint and spent diesel.

4.6.2 For chemical waste produced from a process, as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, registration will be made with EPD as a Waste Producer.

Estimated Quantity and Timing for generation

4.6.3 The generation of chemical wastes from the maintenance of plant and equipment is anticipated throughout the demolition project based on the utilisation of plant and equipment. The maintenance of plants and equipments will be minimized conducted on site except emergency maintenance. It is estimated that the generation of chemical waste is 75L per month (approx. 64kg/month).

Control Measures

4.6.4 Preventive measures will be implemented for leakage and spillage of fuel and lubricating oil to avoid contamination of the construction site.

4.6.5 All plant and equipment will require regular maintenance. Their maintenance records will be kept in site office for future reference.

4.6.6 Good housekeeping practices will be adopted to deal with chemical waste include:

(i) Generating less chemical waste through:

· Delivering appropriate quantity of chemicals to the construction site.

· Avoiding unnecessary wastage of chemicals by using the chemicals more sensible and in accordance with the manufacturer’s instructions.

· Finishing one bottle/container of chemicals before opening the next one for use.

· Collecting the remaining chemicals in suitable containers.

· Removing the unused chemicals out of the construction site after completion of the project.

(ii) Preventing illegal discharge of chemicals or chemical wastes through staff of the project.

(iii) Minimising the volume of unused chemicals to be disposed of through:

· Using the chemicals before the expiry date.

· Ordering appropriate quantity of chemicals and avoiding unnecessary storage of excess chemicals.

On-site Handling and Storage

4.6.7 Chemical waste will be handled in accordance with the Code of Practice on the Packaging, Handling and Storage of Chemical Waste. The details are described as follows and the location of temporary storage area of chemical waste is indicated in Figure 4-1.

(i) Containers used for the storage of chemical waste will:

· be suitable for the substance they are holding, resistant to corrosion, maintained in a good condition, and securely closed;

· have a capacity of less than 450 litres unless the specification have been approved by EPD; and

· display a label in English and Chinese in accordance with instruction prescribed in Schedule 2 of the Regulations.

(ii) The storage area for chemical waste will:

· be clearly labelled and used solely for the storage of chemical waste;

· be enclosed on at least three sides;

· have an impermeable floor and bund, 110% capacity of the largest container or 20% of the storage capacity, whichever is the greatest;

· have adequate ventilation;

· be covered to prevent rainfall entering (water collected within the bund must be tested and disposed as chemical waste if necessary); and

· be arranged so that incompatible materials are adequately separated.

Disposal Arrangement

4.6.8 Chemical waste will be disposed of:

· via a licensed waste collector;

· to a facility licensed to receive chemical waste, e.g. Chemical Waste Treatment Facility in Tsing Yi; or others

· to a re-user of the waste, under the approval from the EPD.

5 IMPLEMENTATION OF WASTE MANAGEMENT

5.1 Waste Flow Table (WFT)

5.1.1 Waste Flow Tables will be used to record all waste removed off site each month.

5.1.2 The estimated and actual quantities of wastes that will be generated each year from the project will be reported, using the table “Yearly Summary Waste Flow Table”, which is attached in Appendix G of this WMP.

5.1.3 The actual quantities of wastes generated in each month will be recorded in a monthly basis, using the table “Monthly Summary Waste Flow Table”, which is attached in Appendix G of this WMP.

5.1.4 Site Agent will be responsible to update the Yearly and Monthly Summary Waste Flow Tables.

5.2 Recycling Proposal

5.2.1 As outline in Sections 4, the Contractor will segregate, as far as practical, the recyclable materials (mainly metals), from the C&D waste stream and general waste, so that the recycling contractors can collect the materials on a regular basis for recycling or export. Waste sorting and segregation will be carried out in accordance with the following categories for recycling:

· Plastic (i.e. plastic bag, plastic bottle, plastic packaging, etc.);

· Rubber;

· Paper;

· Wood/ timber;

· Glass;

· Textile; and

· Metal (i.e. aluminium can, steel metal, ferrous metal, and non-ferrous)

5.3 Trip-ticket System

5.3.1 The disposal of C&D Material will be carried out in accordance with the ETWB TC(W) No. 31/2004. The Contractor will produce a Construction and Demolition Material Disposal Delivery Form (the Form) for each and every vehicular trip transporting C&D material off site. The Contractor will complete all relevant details on the Form in quadruplicate except for the Time of Departure. A sample of the Form is attached in Appendix H. All inert C&D material will be disposed of by marine transport to the public fill area or other areas as designated by EPD. Vessel chits forms should be used for C&D material disposal of at public fill area by barge.

5.3.2 Prior to the vehicle leaving the site, the Contractor will present to the ER the completed Form. The ER will insert the Time of Departure and stamp the Form. The ER will retain a copy of the Form and return the original to the Contractor. The Form will be carried on board the vehicle at all times throughout the vehicular trip.

5.3.3 In case marine transportation is employed for disposal of inert C&D material, the Contractor follow the vessel trip-ticket system arrangement for all barges to deliver to designated public fill area. For disposal of ACM, the Contractor still needs to follow the aforesaid trip ticket arrangement for all trucks when materials are transferred from the barges to the trucks at existing barging point nearby the disposal site before the trucks are allowed to dispose of the collected materials at the designated sites.

5.3.4 The copies of the Form and the receipt will be maintained on site for future references.

5.3.5 For each trip of off-site disposal of chemical waste, trip tickets issued for every chemical waste collection made by the licensed waste collector will be copied to the ER with the original maintained on site for future references.

5.3.6 The Site Management Plan for Trip-Ticket System is attached for reference in Appendix H.

5.4 Inspection Programme and Performance Monitoring

5.4.1 Auditing of each waste stream will be carried out periodically by the EM&A Team to determine if wastes are being managed in accordance with approved procedures. The audits will look at all aspects of waste management including waste generation, storage, recycling, treatment, transport, and disposal. An appropriate audit programme would be to undertake a first audit at the commencement of the demolition works, and then to audit quarterly thereafter.

5.4.2 The Waste Manager and the ET will be responsible for the monitoring and auditing of the waste management practice during his weekly site inspection in order to ensure that appropriate control measures are properly implemented.

5.4.3 If deficiency of the waste control measures were identified during the site inspection and audit, the Waste Manager of the Contractor will discuss with the Site Agent for formulation of remedial measures and the Site Agent will implement the remedial measures promptly to rectify the situation. If deficiency persists, alternative and/or additional control measures will be proposed to the satisfaction of the ER.

5.5 Record Keeping and Reporting

5.5.1 The Contractor will keep adequate and proper records such as trip tickets, photographs and measurement records relating to the implementation of the WMP, and submit such records of each calendar month to the ER within the first week of the following calendar month for their onward submission to the Public Fill Committee for information. The record will include the amount of wastes generated, recycled and disposed of (including the disposal sites). A sample of the Construction and Demolition Material Disposal Delivery Form is included in Appendix H for reference.

5.5.2 After the completion of the Contract, the Contractor will submit a report on the implementation of the WMP in the content to be agreed by the ER. The report will include the following information and any other information as the ER may consider appropriate:

· The quantities of different types of C&D material as estimated at the commencement of the Contract;

· A statistics on the monthly quantities of different types of C&D material generated and their disposal method; and

· Reasons for any significant differences between the estimated quantities at (a) and the actual quantities at (b).

6.8 Training

6.8.1 An emergency often creates unfamiliar circumstances and a hostile working environment for people required to respond to the emergency. In addition, time is usually a very important factor in determining the most appropriate response to an emergency. Training and experience can significantly improve the effectiveness of the responders and decision-makers. Training is therefore a vital part of the implementation of an Emergency Response Procedure (ERP).

6.8.2 The specialist personnel identified in this procedure will be trained and qualified in their respective roles as identified in this procedure. For example, it will be ensured that all First Aiders hold valid First Aid Certificates.

6.8.3 All workers will be briefed of the emergency response process in the site induction, and all workers identified in this section will be trained in its content in the language that the worker understands.

6.9 The Contractor and Employees

6.9.1 All employees of the Contractor shall be thoroughly familiar with company policies and procedures for responding to emergencies. He/she will be knowledgeable in the contents under this section of the plan, and be actively involved in the training of other personnel identified under this section.

6.9.2 All personnel at the site will be made familiar with the Chain of Command with respect to reporting emergencies and subsequently taking directions from identified personnel. Every person is a potential resource in the early detection of problems, which if not reported and not addressed could lead to emergency situations.

6.9.3 The frequency of the training necessarily depends on the personnel and the circumstances at the site. New personnel should be trained systematically. Changes in the roles of individual personnel would warrant new training.

6.10 Sub-Contractors and Others

6.10.1 Sub-contractors and all other personnel working at the site shall be made familiar with the chain of command with respect to reporting emergencies and subsequently taking directions from site personnel.

6.11 Emergency Response Procedures

Response to General Emergency

6.11.1 Where the ERT leader deems an emergency situation, he will contact the necessary personnel identified in the ERT. The Safety Officer will go to the site of the incident and relay all details to the other ERT members who will gather at the contractor site office. The Safety Office will advise the ERT of all necessary equipment/PPE requirements/first aid treatment needed at the accident site. The ERT and associated team members will then co-ordinate all items require by the Safety Officer.

6.11.2 Upon clearing the accident site, a post-mortem report will be completed which details all occurrences prior to, during and following the incident. Applicable workers will be briefed on the contents of the incident report following its completion.

Fire in Full Containment for ACM / DCM Decontamination

6.11.3 In the event of fire in full containment for ACM / DCM decontamination, the Fire Services Department will be immediately notified and all personnel working within the containment or in the vicinity of the work site area evacuated. All personnel working within the containment shall:

· Stop all work and if necessary remove worker(s) to a safe area;

· If a worker has collapsed remove face mask (in all other cases the face mask should be left in place), carry out normal emergency first aid procedures and arrange to transfer the worker to hospital. Personal decontamination should be carried out if possible;

· Where it is impossible to carry out decontamination procedures on the worker, inform the medical team to enable them to take the appropriate safety measures;

· Bag all loose ACM / DCM debris present in the ACM / DCM removal work area and remove to a secure store. Wipe clean and vacuum all surfaces and any adjoining area contaminated during the emergency;

· Spray all surfaces and debris within the ACM / DCM removal work area with amended water in a fine mist spray, using airless spray equipment once the fire has been extinguished and the Site is safe for re-entry;

· Prepare the Site for inspection by the Registered Asbestos Consultant; and

· Carry out air testing prior to recommencing removal work.

Chemicals & Chemical Wastes Spillages on Land and Sea

6.11.4 Transportation of chemical waste including ACM / DCM and other chemicals shall be carried out by barge, loss of ACM / DCM and other chemical waste on roads are not anticipated.

6.11.5 Transportation of chemical waste including ACM / DCM and other chemicals shall be carried out by licensed waste collector, and be contained either in steel drums lined with plastic sheeting or by use of safety and suitable labelled containers.

6.11.6 Spillages or dropping into the sea while marine transportation shall be recoverable. Detail of the Works Execution Plan for transportation by vessels is included in Appendix H for reference.

6.11.7 While ACM / DCM are being loaded onto and off between barging point and the barge for marine transport, net carrier shall be used to prevent damages and dropping on land and sea.

Typhoon Attack on Decontamination Containment

6.11.8 In order to prevent water retention on the site (in particular, during decontamination of ACM), all storm and surface water drains, ditches and out-falls will be regularly checked and if necessary cleared of debris, soil and litter. Frequency of checking and clearing will increase during the typically wet months (June to August). Additionally, the drains, ditches and out-falls will be checked when heavy rainfall events are forecasted (including when an Amber Rainstorm Warning is hoisted) to confirm that these surface water management features are not obstructed.

6.11.9 After intense rainfall events such as Red or Black Rainstorm Warning or Typhoons, inspections and necessary actions (such as maintenance or repair of damaged drainage items) will be carried out.

6.11.10 The transportation of ACM / DCM will cease when warnings for a Black rainstorm and/or Typhoon signal No. 8 are given.

6.11.11 When warnings for a Black rainstorm and/or Typhoon signal No. 8 are given, the Contractor shall:

· Stop all processes which may result in the production of ACM / DCM dust;

· Spray all surfaces and debris within the ACM / DCM removal work area with amended water in a fine mist spray, using airless spray equipment;

· Bag all loose ACM / DCM debris present in the ACM / DCM removal work area and remove to a secure store. Wipe clean and vacuum all surfaces;

· Cut off all power and water supplies and secure all loose equipment against typhoon damage;

· Arrange a revised inspection by the Site Agent and Site Engineer before the workers leave Site;

· Recommence the ACM / DCM removal works once the No. 8 typhoon signal has been lowered, the necessary cleaning up work and repairs to containment have been completed and permission has been given by the Site Engineer.

6.11.12 If during the course of abatement work, a worker collapses or some other accidents occur, the victim should follow normal decontamination procedures with assistance from fellow workers before exiting the work area. For life-threatening situation, however, decontamination should take a lower priority and every effort should be made to ensure the victim receives immediate medical treatment. Any area contaminated during the emergency should be thoroughly cleaned by wet wiping and HEPA vacuuming at the earliest opportunity, and verified by the registered asbestos supervisor and approved by the registered asbestos consultant before work is allowed to continue.

6.11.13 In addition, the construction of containment is governed by the “Code of Practice on Asbestos Control, Asbestos Work Using Full Containment or Mini Containment Method”, Section 6 – Construction of Containment. Under which, the registered asbestos consultant is also responsible for the structural safety of the containment, and for the provision of safe means of access as well as alternative escape route for emergency situations. Sections extracted from the “Code of Practice on Asbestos Control, Asbestos Work Using Full Containment or Mini Containment Method” with regard to the construction, maintenance and emergency procedures for use of the containment approach are included in Annex V of Appendix D for reference.

Overflow of Contaminated Surface Run-off Due to Heavy Rain Storm Attack

6.11.14 As mention in Section 6.9.5, in order to prevent water retention on the site, all storm and surface water drains, ditches and out-falls will be regularly checked and if necessary cleared of debris, soil and litter. Owing to the nature of the Project, removal of ACM / DCM, solidification pilot test, and the actual cement solidification process shall be carried out under “full containment” approach.

6.11.15 Treatment and storage for the ACM / DCM removed shall strictly follow the Asbestos Abatement Report (Appendix 25 to the PS). As such, none of the removed ACM / DCM will be exposed to the surface run-off due to heavy rain storm in its untreated stated, overflow of contaminated surfaces of the ACM / DCM is not anticipated.

On-site Traffic Accident

6.11.16 On-site traffic accident will be minimised by speed control limit for all vehicle to 5 km/hr. In additional, all storage area of ACM / DCM shall form within a fenced / protected area and/or are inside existing buildings of the project site.

6.11.17 All vehicles shall only be driven by personnel who have been trained in the Emergency Response Procedure and hold a valid Hong Kong driving licence for the class of vehicle operated.

Power Failure during ACM / DCM Decontamination

6.11.18 In the event of loss of power, back-up power will be available from portable generators. These units are readily available in the event of a disruption to the power supply.

6.11.19 Appropriate back-up facilities will be supplied in order to ensure the effective operation of the site and associated ACM / DCM decontamination containment when the standard facilities are out of action due to power failure.

6.12 Post-Emergency Procedures

6.12.1 An investigation will be carried out immediately after incident occurred. It aims to find out the causes of such incident. Base on this information, adequate preventive measures as well as toolbox training to relevant staffs will be provided in order to minimize the probability of recurrence. A post-mortem report of emergency incident including mitigation and preventive measures shall be submitted to the authorities.
