1 INTRODUCTION

1.1 Background

Environmental protection and sustainable development are part and parcel of the daily operations of the Gammon Construction Limited (referred to hereinafter as the GCL). GCL will initiate appropriate actions in order to minimize, and where possible eliminate, the environmental impact arising from the construction of this project.

1.2 Project Descriptions

Gammon Construction Limited (GCL) has been awarded of the Contract No. HY/2012/07 – Tuen Mun Chek Lap Kok Link – Southern Connection Viaduct Section for Highways Department (HyD) of the Government of the Hong Kong Special Administrative Region (HKSARG). The Works to be executed comprise the design and construction of a dual 2-lane elevated carriageway between the HZMB HKBCF and North Lantau Highway (NLH) with associated slip roads, as well as modifications and realignment of sections of the NLH and Cheung Tung Road at North Lantau, and associated works.

2 PURPOSE OF THE PLAN

The Waste Management Plan (WMP) has been prepared to describe the arrangements for minimising the generation of construction and demolition (C&D) materials and disposing of the surplus C&D materials during the course of the Works.

This contract-specific WMP shall be deposited to the Director of Environmental Protection in accordance with the Condition 2.10 of the Environmental Permit No. EP-354/2009/A..

The WMP shall address the potential and actual impacts and necessary mitigation measures in light of the preferred construction programme and consists of the following:-

· A review of the ordinances, regulations, codes of practices as well as contractual obligations that are applicable to the wastes arising from the Works;

· An organisation chart setting out the roles and responsibilities of the GCL’s personnel responsible for waste management and appropriate mitigation measures;

· An analysis of timing, quantities and types of C&D materials are anticipated to be generated in the course of the execution of the Works;

· A classification of C&D materials into inert portion (Public Fill) and non-inert portion (C&D Waste);

· Proposals for avoiding/minimizing, handling, recycling, reuse, return, storage and disposal of C&D materials, chemical waste and general refuse;

· An appraisal of the potential establishment on site of a sorting facility, including the identification of potential area on-site of facilitate the waste sorting;

· A proposal for maintaining the site in a clean and tidy condition;

· A monitoring and auditing proposal to ensure that the requirements of the WMP are properly implemented.

3 WASTE MANAGEMENT POLICY AND STRATEGIES

3.1 Principles

The principles of waste management adopted in this project shall be in line with Gammon's environmental management system which follows the requirements of the ISO 14001 and based on a cyclical process comprising policy, planning, implementation & operation, checking and corrective action and management review. A policy statement is given in Appendix A. Core elements of waste management are listed in Table 3.1 below and described in the following sections of the WMP:

3.2 Hierarchy

The various waste management options shall 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:

· Avoidance and minimisation, i.e. not generating waste through changing or improving practices and design;

· Reuse of materials, thus avoiding disposal;

· Recovery and recycling, thus avoiding disposal; and

· Treatment and disposal, according to relevant laws, guidelines and good practice.

This hierarchy shall be used to evaluate waste management options, thus allowing maximum waste reduction. Waste reduction measures shall be introduced at the detailed planning stage and carried through the construction activities, whenever possible, by careful purchasing control, reuse of formworks and good site management. By reducing or eliminating over-ordering of construction materials, waste is avoided and costs are reduced both in terms of purchasing of raw materials and in disposing of wastes.

8 WASTE CLASSIFICATION AND CONTROL MEASURES

The waste generated from the construction activities shall be divided into distinct categories based on their composition, as follows:

(a) Construction and demolition (C&D) materials

(i) Inert C&D materials

(ii) Non-inert C&D materials

(b) Chemical wastes

(d) Dredged marine sediments

(i) Uncontaminated marine sediments (Cat. L )

(ii) Contaminated marine sediments (Cat. M_p & M_f)

A quantities of excavated materials to be generated, reuse on- or offsite during works has been estimated and shown in Appendix D. 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 as shown in Appendix E. All anticipated disposal scenarios and transportation modes are summarized in Appendix F.

8.1 Construction and Demolition (C&D) Materials

C&D materials comprise unwanted materials generated during construction, including rejected structures and materials, materials which have been over ordered or are surplus to requirements, and materials used and discarded.

C&D material could be divided into two categories according to whether they are inert or non-inert. Inert C&D material are known as rock, rubble, boulder, earth, soil, sand, concrete, asphalt, brick, tile, masonry and used bentonite, where to be maximized the reuse of these materials within the Contract and to be disposed of the surplus of these materials to other Contracts, subjected to the approval or direction of Supervising Office Representative (SOR). Under any circumstances that no site is able to receive the unsuitable C&D materials for the filling purpose, GCL will apply to CEDD for the public fill reception facilities (PFRF) as a back-up option.

Non-inert C&D material are such as metal, timber, vegetation, packaging waste, organic material and all recyclables and non-recyclables is called “C&D Waste”. C&D waste, excluding recyclables, shall be disposed of at NENT Landfill.

Recyclables are mainly metals, paper/cardboard packaging and plastics. Plastics refer to plastic bottles/containers, plastic sheets/foam from packaging material. Recyclables would be collected by relevant recyclers. Non-recyclable materials are treated as general refuse.

The following general low waste construction designs and principles together with careful planning shall be adopted to avoid/minimise C&D material generation. Such measures include: -

(a) Management of construction materials such that over-ordering, poor storage and maintenance, mishandling as well as improper operation procedures shall be avoided.

(b) Restriction on use of hardwood such that softwood, metal props and/or proprietary steel system shall be considered for false work and the shoring of trenches and pits;

(c) The formwork shall be designed to maximise the use of standard wooden panels so that high reuse levels can be achieved. More durable alternatives such as steel formwork or plastic facing shall be considered for repetitive areas to increase the potential for reuse.

(d) C&D materials shall be, as much as possible and practicable, separated into reusable items and materials to be disposed of or recycled. It shall be conducted at the immediate working area to avoid loss/leakage and cross contamination during handling.

(e) All C&D materials arising from or in connection with the construction and demolition work shall be sorted on-site and be separated into different categories for disposal at landfills, public filling areas, or reuse and recycling as appropriate. The sorting area may be revised from time to time in order to suit the construction activities.

(f) Useful materials such as timber, rubble and steel/metal shall be segregated for reuse. For example formwork and timber shall be cleaned for reuse, off-cuts of reinforcement shall be sorted into usable lengths and short off cuts stacked for scrap metal. Where it is no longer reusable, scrap steel and metal items will be collected by recycling companies.

(g) Segregated materials shall be temporarily stored at designated areas for reuse on site. Steel will be stored at the reinforcement yards, timber at the formwork yard and rubble in a stockpile (either covered or sprayed to control dust). Cardboard and paper packaging recovered from site shall be properly stockpiled in dry condition and covered.

(h) In order to avoid over-order of concrete, accurate calculation shall be made prior to concrete pouring. Close supervision shall also be arranged during concrete pouring to avoid over-cast.

(i) Surplus concrete shall be used for paving of temporary road or cast of concrete blocks for bunding etc. as far as practicable. In case immediate use of surplus concrete cannot be identified, the surplus concrete will be temporarily poured into designated surplus concrete pouring areas on site for further disposal to public filling areas.

(j) Entirely cover every stock of more than 20 bags of cement by impervious sheeting and carry out the de-bagging, batching and mixing processes in an area sheltered on the top and the 3 sides. Damp and gather the waste cement bags for proper disposal.

(k) Used bentonite shall only be disposed of at Public Fill area.

GCL designate suitable areas onsite for the storage, sorting and segregation of construction waste. The areas that are designated by GCL will be clearly defined with appropriate signage and barriers (or similar) and allow for easy access by workers and vehicles. As the project progresses it is anticipated that the designated areas will be reviewed depending upon construction program requirements. The areas designated by GCL will be sufficient for the amounts of construction waste that are anticipated to be generated during the course of the contract. The sorting mechanism is shown in Table 8.1. The tentative locations for the temporary storage and sorting of C&D waste are shown in Appendix G.

Table 8.1 Sorting of C&D Materials

Type of C&D Material	Required Action
Rock	Reuse on site where possible or recycle off site
Excavated material	Reuse on site where possible or dispose of at approved landfill facility
Excavated Marine Deposits	Dispose of offsite at approved location
Concrete	Sorted and segregated onsite, reuse on site where possible or recycle offsite
Metal	Segregate and recycle offsite
Paper/Cardboard Materials	Segregate and recycle offsite
Plastics	Use recycling containers and recycle offsite
Aluminium Cans	Use recycling containers and recycle offsite

8.4 Marine sediments

Marine sediment means excavated from the Works of the foundation and associated substructures at the sea. It could be classified as contaminated and uncontaminated based on its contamination level with reference to Chemical Exceedance Level (CEL) laid down in the Appendix A of the ETWB TCW No. 34/2002. The excavation and disposal of marine sediments generated shall be minimized from the Works in this Contract, 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 GCL shall handle/ process such marine sediment in accordance with the procedures given in ETWB TCW No. 34/2002. GCL will apply to the EPD for all valid permits and licenses 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. The copy of memo from Marine Fill Committee of CEDD granting the allocations for the sediment disposal space is attached in Appendix H.

8.4.1 Cat. L / Cat. M_p Marine Sediments

In case of disposal of any amount of the marine sediment in Hong Kong waters, the dumping of sediments shall be strictly within the designated sediment disposal sites and shall be controlled through a dumping permit issued under the Dumping at Sea Ordinance (Cap 466), or called a DASO permit, by the Director of Environmental Protection. Dumping shall take place at sub-areas within the sediment disposal sites, the locations of which will be changed from time to time as notified by the Director of Environmental Protection through the Supervising Officer.

Subject to the instruction of SO, notwithstanding whether the GCL elects to dispose of any or all dredged/excavated marine sediments at the designated sediment disposal sites in Hong Kong, the GCL will apply for approval to relevant authorities in Mainland and Hong Kong for the cross-boundary disposal of Cat. L and M_p sediments at the tentative disposal site of South Dangan Liedao (擔杆列島). This cross-boundary disposal option shall only proceed with the Supervising Officer’s instruction. In the event that the approval of cross-boundary disposal is not obtained in a timely manner, Cat. L and M_p sediments would be arranged to dispose of at South Cheung Chau Open Sea Sediment Disposal Area and East Sha Chau or South of the Brothers Marine Sediment Disposal Facility as a fallback option to be authorized by Supervising Officer, EPD and CEDD-MFC.

In cases that off-site disposal of marine sediment in Hong Kong Water required, GCL shall apply for the allocation of a sediment disposal site in the name of Highways Department of the HKSAR, and marine loading permits under Dumping at Sea Ordinance (Cap. 466) (DASO) for the disposal of marine sediment at the designated disposal facilities in Hong Kong.

8.4.2 Cat. M_f Marine Sediments

The marine sediment of Category M failing biological tests as defined in ETWB TC(W) No. 34/2002 shall be disposed of in CEDD-MFC's designated contaminated mud pits in Hong Kong waters, at mud pit of East Sha Chau or South of the Brothers Marine Sediment Disposal Facility as allocated by CEDD-MFC. GCL shall place the contaminated mud at a location and in a manner as directed on site by the CEDD management team. GCL shall proceed with the disposal operation as instructed by the management team and in accordance with the relevant sections of the Requirements of the Contaminated Mud Pit Management Scheme which may be modified from time to time by the management team. GCL shall not carry out any dumping without permission of the management team or when the management team is not in operation. GCL will carry out the dumping operation in strict accordance with the method statement agreed by the Licensing Authority.

9 WASTE MONITORING AND AUDITING

9.1 Trip-Ticket System

In accordance with DEVB TC(W) No. 6/2010, with tender invitation was on or after 1 November 2010, the administration of CHIT/ DDF was streamlined. CHIT in lieu of the bar-coded Disposal Delivery Form (DDF) should be used at all prescribed facilities, i.e. public fill reception facilities, sorting facilities, outlying island transfer facilities and landfills. Moreover, under the Construction Waste Disposal Charging Scheme, GCL registered with EPD a disposal account and will adopt the CHIT as the enhanced control of C&D material disposal. The control procedure on off-site disposal of C&D materials is shown in Appendix I. The sample of CHIT is given in Appendix J.

Every C&D material disposal trip to the public fill reception facilities and designated landfill shall be controlled under the trip-ticket system as per the DEVB TC(W) No. 6/2010 in order to avoid fly-tipping. Appendix G gives the site procedure for the TTS operation.

For disposal of chemical wastes, the trip-ticket system as per the Waste Disposal (Chemical Waste) Regulation in which licensed collector will be employed and the chemical wastes be disposed of at designated chemical waste treatment facility.

GCL will inform all truck drivers engaged for removal of C&D materials from the Site of the following particular points:

· Each truck carrying C&D materials leaving the Site for a disposal ground must bear a duly completed CHIT, 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 SOR or alternative disposal grounds approved by the SOR.

GCL would formulate 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 J.

9.2 Inspection Programme

GCL shall arrange weekly inspection attended by the Environmental Officer and SOR to inspect the site to ensure satisfactory performance on compliance with the WMP with due regards to the followings:

(a) Inert C&D materials suitable for recycling into aggregates are recovered and delivered to Tuen Mun Area 38 or other designated recycling facilities as notified by the SOR or the Public Fill Committee (Port Works Division of CED);

9.3.1 Daily Record Summary

Daily Record Summary (DRS) shall be filled by designated persons.to record every truck for delivery of C&D materials. The sample of DRS is given in Appendix L.

9.3.2 Monthly Summary Waste Flow Table

As part of the WMP, a mechanism shall be established to record the quantities of C&D materials generated each month, using the monthly summary “Waste Flow Table” (WFT) as given in Appendix E.

9.3.3 Yearly Summary Waste Flow Table

Estimated quantities of C&D materials that will be generated each year from the site the GCL should also be provided, using the yearly summary WFT as given in Appendix D. The yearly summary WFT covering the whole construction period shall be included in the WMP and updated on yearly basis, throughout the construction period in order to account for the revised works programme and latest outturn on the quantities of C&D materials generated from the site.

9.3.4 Performance Monitoring

To ensure the effectiveness of the Trip-Ticket System, the following item will be discussed at every Site Safety and Environmental Management Committee meeting, and Site Safety and Environmental Committee meeting or ad-hoc meetings on as-needed basis:

1. Review the site management plan and implementation of the TTS, and identify areas for improvement;

2. 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;

3. Review incidents of non-compliance and discuss the necessary follow-up actions for TTS; and

4. Monitor the follow-up action on defects and deficiencies identified.

10 TRAINING

The Environmental Officer and other site personnel (if they have not attended similar course before) shall be arranged to attend training on waste management organised by training institutes or organisations as considered appropriate.

The Environmental Officer shall arrange and provide training on waste management in the site-specific induction and its refresher training for all persons employed by the GCL or his subcontractor on the Works or in connection with the Contract. The training should cover the waste management policy, targets, measures for on-site sorting of C&D materials and measurement on waste management performance on the Site. According to ER requirement, induction training shall be carried out within first 2 days of the employment and refreshment training shall be carried out by every 6 months.

The Environmental Officer is allowed to develop and provide toolbox talks for the topic on on-site sorting of C&D materials to promote the workers' awareness on handling, sorting, reuse and recycling of C&D materials. Training material for environmental toolbox talks with regard to waste management shall be prepared by the Environmental Officer and disseminated to supervisor/foremen and subcontractor’s representatives for conducting tool-box talks to all workers or labourers at regular intervals.

11 MITIGATION MEASURES IN EIA

The Section 12.6 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.

12 MITIGATION MEASURES IN EM&A Manual

The Section 8.1.2 of the EM&A Manual gives recommendations on mitigation measures of waste management, which are:

· The waste management hierarchy below should be strictly followed. This hierarchy should be adopted to evaluate the waste management options in order to maximise the extent of waste reduction and cost reduction. The records of quantities of waste generated, recycled and disposed (locations) should be properly documented.

· A trip-ticket system should be established in accordance with DEVB TC(W) No. 6/2010 and Waste Disposal (Charges for Disposal of Construction Waste) Regulation to monitor the disposal of public fill and solid wastes at public filling facilities and landfills, and to control fly-tipping. A trip-ticket system would be included as one of the contractual requirements for the Contractor to strictly implement. The Engineer would also regularly audit the effectiveness of the system.

· A recording system for the amount of waste generated, recycled and disposed (locations) should be established. The future Contractor should also provide proper training to workers regarding the appropriate concepts of site cleanliness and waste management procedures, e.g. waste reduction, reuse and recycling all the time.

· The CEDD should be timely notified of the estimated spoil volumes to be generated and the Public Fill Committee should be notified and agreement sort on the disposal of surplus inert C&D materials e.g. good quality rock during detailed design of the TM-CLKL project. Wherever practicable, C&D materials should be segregated from other wastes to avoid contamination and to ensure acceptability at public filling areas or reclamation sites.

· The extent of cutting operation should be optimised where possible. Earth retaining structures and bored pile walls should be proposed to minimise the extent of cutting.

· Inert C&D materials from slopes and road pavement will be reused for construction of the raised platform for the toll plaza.

· C&D materials generated by construction of cut slopes along NLH at North Lantau shall be reused in reclamation works where possible.

· The surplus surcharge should be transferred to a fill bank.

· Rock armour from the existing seawall should be reused on the new sloping seawall as far as possible.

· The site and surroundings shall be kept tidy and litter free.

· No waste shall be burnt on site.

· Make provisions in contract documents to allow and promote the use of recycled aggregates where appropriate.

· Prohibit the Contractor to dispose of C&D materials at any sensitive locations e.g. natural habitat, etc. The Contractor should propose the final disposal sites in the EMP and WMP for approval before implementation.

· Stockpiled material shall be covered by tarpaulin and /or watered as appropriate to prevent windblown dust and surface run off.

· Excavated material in trucks shall be covered by tarpaulins to reduce the potential for spillage and dust generation.

· Wheel washing facilities shall be used by all trucks leaving the site to prevent transfer of mud onto public roads.

· Dredged marine mud shall be disposed of in a gazetted marine disposal ground under the requirements of the Dumping at Seas Ordinance.

· Standard formwork or pre-fabrication should be used as far as practicable so as to minimise the C&D materials arising. The use of more durable formwork or plastic facing for construction works should also be considered. The use of wooden hoardings should be avoided and metal hoarding should be used to facilitate recycling. Purchasing of construction materials should be carefully planned in order to avoid over-ordering and wastage.

· The Contractor should recycle as many C&D materials (this is a waste section) as possible on-site. The public fill and C&D waste should be segregated and stored in separate containers or skips to facilitate the reuse or recycling of materials and proper disposal. Where practicable, the concrete and masonry should be crushed and used as fill materials. Steel reinforcement bar should be collected for use by scrap steel mills. Different areas of the sites should be considered for segregation and storage activities.

· All falsework will be steel instead of wood, as far as possible.

· Chemical waste producers should register with the EPD. Chemical waste should be handled in accordance with the Code of Practice on the Packaging, Handling and Storage of Chemical Wastes as follows:

- Suitable for the substance to be held, resistant to corrosion, maintained in good conditions and securely closed;

- Having a capacity of <450L unless the specifications have been approved by the EPD; and

- Displaying a label in English and Chinese according to the instructions prescribed in Schedule 2 of the Regulations.

- Clearly labelled and used solely for the storage of chemical wastes;

- Enclosed with at least 3 sides;

- Impermeable floor and bund with capacity to accommodate 110% of the volume of the largest container or 20% by volume of the chemical waste stored in the area, whichever is greatest;

- Adequate ventilation;

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

- Incompatible materials are adequately separated.

· Waste oils, chemicals or solvents shall not be disposed of to drain;

· Adequate numbers of portable toilets should be provided for on-site workers. Portable toilets should be maintained in reasonable states, which will not deter the workers from utilising them. Night soil should be regularly collected by licensed collectors.

· General refuse arising on-site should be stored in enclosed bins or compaction units separately from C&D and chemical wastes. Sufficient dustbins shall be provided for storage of waste as required under the Public Cleansing and Prevention of Nuisances By-laws. In addition, general refuse shall be cleared daily and shall be disposed of to the nearest licensed landfill or refuse transfer station. Burning of refuse on construction sites is prohibited.

· All waste containers shall be in a secure area on hard standing; Aluminium cans are usually collected and recovered from the waste stream by individual collectors if they are segregated and easily accessible. Separately labelled bins for their deposition should be provided as far as practicable.

· Office wastes can be reduced by recycling of paper if such volume is sufficiently large to warrant collection. Participation in a local collection scheme by the Contractor should be advocated. Waste separation facilities for paper, aluminium cans, plastic bottles, etc. should be provided on-site.

· Training shall be provided to workers about the concepts of site cleanliness and appropriate waste management procedure, including waste reduction, reuse and recycling.
