0. PROCEDURE OF REVIEW AND DISTRIBUTION (1) Site Agent and Environmental Officer will review, update and distribute the Waste Management Plan every

month in accordance with the recommendations given by Site Safety & Environmental Management Committee (SSEMC) and /or Site Safety & Environmental Committee Meeting (SSEC).

(2) Holder of this Waste Management Plan will be provided with all subsequent revisions, amendments and

additions. It is the responsibility of the holder to ensure this copy is kept up-to-date by inclusion of all amendments.

0.1 INTRODUCTION Disposal of public fill at public filling areas and mixed Construction and Demolition (C&D) waste at landfills has been the major approach for C&D materials management. For sustainable development, we can no longer rely solely on reclamation to accept most of the C&D materials. As such, the government is examining ways to reduce and also to promote the reuse and recycling of C&D materials. Nevertheless, there will still be a substantial amount of materials that require disposal, either at reclamation sites or at landfills.

Waste Materials Type

Handling methods/Reuse

C&D Materials Inert C&D materials –Rock and Soft Materials

• Segregation from non-inert C&D materials during stockpiling and transportation

• Stockpile area (if required) should be well managed with covers and water spraying system

• Reused in reclamation of the Project, delivered to PFRFs for beneficial use in other projects or to Lam Tei Quarry for recycle

Non-inert C&D materials – Timber, Papers and Plastics

• Segregation from inert C&D materials during stockpiling and transportation

• Reusable materials should be separated and recycled as far as practicable

Chemical Waste • Store in compatible containers in designated area on site

• To be collected and recycled by licensed collectors

General Refuse • Provide on-site collection points together with recycling bins

• Collected by licensed collectors

We will ensure that this project will be implemented in full compliance with the requirements of Environmental Permit (EP-458/2013/B) Section 2.6 and the Particular Specification and hope Wing Lee’s every little to preserve environment can add up to yet another beautiful morning to our next generation.

“This is no Plan B because there is no planet B” Purpose of this Waste Management Plan A waste management plan provides an overall framework for waste management and reduction. It identifies major waste types and defines ways for waste reduction.

Chemical waste handling procedures

Chemical waste products should make the necessary arrangements and provide adequate supervision to prevent any danger or injury arising from the handling of chemical waste. General Requirements - Workers handling chemical waste should be competent and trained. - Regular inspection of the storage area and its access should be made to ensure that it is free from obstruction and is

kept dry and clean. - Containers should be checked for leakage or spillage before use. - Stacked containers should made stable and safe from falling down. - Incompatible wastes should be stored separately. - Inventory of the types and quantities of chemical wastes being stored should be kept and regularly updated. - No person should be allowed to eat, drink or smoke in the chemical waste storage area. Warning signs indicating

"NO SMOKING, NO EATING, NO DRINKING" should be posted at the storage area. - Unauthorized persons should not be allowed to enter the storage area. Warning Signs at the Chemical Waste Storage Area Every chemical waste storage area, including any cupboard, cabinet or bin, should display a hazard warning panel, notice or marking at or near the entrance or opening of the storage area and such panel, notice or marking should-

- Indicate the English words and Chinese characters "CHEMICAL WASTE""化學廢物 "clearly and boldly in red on a

white background with a letter/character size of not less than 60 mm high. - Be securely attached to or worked on a vertical plane of the storage structure. - Be weather resistant and rigid. - Be kept clean and free from obstruction. Safety Training and Equipment Waste producers should provide adequate safety information, training and equipment for employees or any other persons involved in the handling of chemical waste. Specifically, a waste producer should- - Make available 'Safety data sheets' of all the chemicals which result in chemical waste generation, for easy reference

by the persons concerned. - Ensure that all employees understand the hazard symbols and the safety precautions in relation to the chemical

wastes generated. - Provide the necessary safety equipment and ensure that such equipment is used by the employees in handling

chemical waste. Safety equipment should also kept in good condition and be cleaned regularly. Adequate first aid equipment should also be kept near the storage area.

(3) Managing Subcontractors It can be very difficult to coordinate waste management on sites where there are a number of subcontractors. Some supervision are suggested as follows:

• Many sites are now using a system of allowable waste percentages. In the early pre-work agreements the site manager decides how much waste is acceptable, and agrees a percentage with the subcontractor.

If they waste more than the agreed amount, they can be charged the extra costs. This is a great incentive to reduce wastes by efficient use of materials. The lower the allowable percentage, the more care people will take with materials. Setting the right level is crucial. Allowable wastage percentages can be applied to all materials or restricted to those that are expensive or commonly generate excessive wastage.

• Make subcontractors responsible for both purchasing the raw materials they need, and disposing of any waste material from their activities. This will give them a direct financial incentive to use materials efficiently with the minimum of wastage.

• Make subcontractors aware of wastage and the costs involved in dealing with wastes.

• Hold regular meetings to discuss wastage on site.

(1) Estimation

The first step in implementing a waste minimization programme is to estimate the quantity of construction wastes that will be generated from projects. Instead of PS-Appendix 27.01 “Yearly Summary Waste Flow Table/Monthly Summary Waste Flow Table & ” Summary Table for Work Processes or Activities Requiring Timber for Temporary Works”, it can be done using the standard forms under Environment, Transport and Works Bureau Technical Circular (Works) 15/2003 “Waste Management on Construction Sites” – Annex I & II to Appendix C.

• Monthly Summary Waste Flow Table for Contracts with Waste Management Plan under ETWB TCW No.15/2003

• Quarterly Summary Waste Flow Table for Non-PFSES Contracts or PFSES Contracts exempted from full WMP requirement under ETWB TCW No.15/2003

(Quarter Ending : Feb/May/Aug/Nov)

• Half-yearly Summary Waste Flow Table for Contracts with Waste Management Plan under ETWB TCW No.15/2003

Waste Materials Type Estimated Disposal Quantity (EIA Report No. AEIAR-173/2013)

Estimated Disposal Quantity (NE/2015/03 takes 0.6% of the total contract value of the project in EIA Report No. AEIAR-173/2013 )

Inert C&D materials (e.g. Broken Concrete, etc.)

4,172,420 m3 4,172,420 m3 x 0.6% = 25,034 m3

Non-inert C&D materials (e.g. Timber, etc.)

83,000 m3 83,000m3 x 0.6% = 498m3

General Refuse Unknown at this stage 500m3

Inert C&D materials - The amount of concrete waste, for example, can be estimated if the material waste level of concrete is known.

Recent research indicated that the average waste level is about 4%, which is considered the norm for the concreting trade. However, it could be reduced to 3% if careful material ordering and handling is applied. The amount of waste can be estimated according to:

Quantity of Concrete Works (m3) × Material Wastage (%) - Inert granular waste generated by blockwork and brickwork is estimated to be 10% of the quantity of this work

required in the project. The estimate can be calculated according to:

Quantity of Work Done (m2) × Thickness (m) × Material Wastage (%) - The waste from screeding and plastering which higher wastage of 15% is given as the norm since these trades are

difficult to control. The estimate can be calculated according to:

Quantity of Work Done (m2) × Thickness (m) × Material Wastage (%)




REV2 13

Non-Inert C&D materials

- Timber formwork is assumed to have been used at least 12 times before being discarded. The timber waste can be

estimated according to:

Quantity of Formwork (m2) × Thickness (m) × 12 (No. of Uses) - Contractors have little control on the quantity of packing wastes produced, which is estimated at 5% of the volume

of the materials that required packing, hence

Volume of Packaged Construction Materials × 5%. (2) Removal of Waste Materials {PS1.66}

Management Review

(1) Causes of Waste on Site

(i) Site Management and Practices

• Lack of a quality management system aimed at waste minimisation e.g. lack of waste management plan

• Untidy construction sites e.g. waste materials are not segregated from useful materials

• Poor handling e.g. breakage, damage, losses

• Over-sized foundations and other elements e.g. over design leads to excess excavation and cut-offs

• Inadequate protection to finished work e.g. finished concrete staircases are not protected by boarding

• Limited visibility on site resulting in damage e.g. inadequate lighting in covered storage area

• Poor storage e.g. pallet is not used to protect cement bags from contamination by ground water

• Poor workmanship e.g. poor workmanship of formwork

• Waste generation inherited with traditional construction method

e.g. timber formwork, wet trade




REV2 15

(ii) Delivery of Products

• Over-ordering e.g. over ordering of concrete becomes waste

• Method of packing e.g. inadequate protection to the materials

• Method of transport e.g. materials drop from forklift

• Inadequate data regarding time and method of delivery e.g. lack of records concerning materials delivery

(2) Reduction of Materials Wastage

Support from the management is vital in order to be successful in the reduction of materials wastage. The following guidelines can be used for the reduction of material wastage.

(i) Material Ordering and Handling

• Purchasing inventory should be carefully controlled to prevent wastage of materials.

• Adopt just-in-time ordering and to ensure materials arrive on site when they are needed, thereby avoiding damage while stored on site and additional moving of materials.

• Order appropriate material sizes to minimize cutting, and order approximate quantities to avoid excess.

• Designate central areas for cutting and storage so reusable pieces can easily be located.

• Do not use tropical hardwood for temporary works. Use metal falsework instead.

• Avoid buying poor quality materials. If the wear-out rate is high, another source of supply should be considered.

• Whenever possible, packing materials should be returned to the supplier for reuse. In some cases the supplier holds a deposit until the pallets are returned.

• Avoid overloading limited storage space on site.

• Avoid unnecessary handling.

• Whenever using timber for a specific purpose, try to avoid treating it with chemicals and using nails, as this will male it difficult to reuse/recycle the timber afterwards.

(ii) Site Management and Practices

• Coordinate with designer and specification writer to ensure dimensional coordination of design with materials and components to minimize cutting waste.

• Coordinate with designer and specification writer to use alternative materials instead of timber.

• Provide training to workers to improve their skill in handling materials and performing construction work.

• Review waste management periodically to identify additional waste reduction alternatives.

• Consider reduction of construction waste and awareness of environmental protection as basic requirements in management.

• Improve construction technology by research or adoption.

• Employ competent subcontractors and skill labourers.

• All metal should be recovered on site for collection by recycling contractors

• All cardboard and paper packaging (for plant, equipment and materials) should be recovered on site, properly stockpiled in dry condition and covered to prevent cross contamination by other C&D materials

• All demolition debris from demolition works should be sorted to recover on site broken concrete,

reinforcement bars, mechanical and electrical fittings as well as other building services fittings/materials

that have established recycling outlets




REV2 18

Other Mitigation Measures

Sorting of C&D Materials Concerning the necessity of maximising reuse for the Project, it is paramount for sorting to be performed to recover the inert materials, reusable and recyclable materials before disposal off-site. All surplus C&D materials arising from or in connection with the works shall become the property of the Contractor when it is removed unless otherwise stated. The Contractor will be responsible for devising a system to work for sorting of C&D materials and promptly removing all sorted and processed materials arising from the construction activities. The system should be included in the EMP, identifying the source of generation, estimated quantity, arrangement for sorting, collection, temporary storage areas (if any) and frequency of collection by recycling Contractors or frequency of off-site removal. It is recommended that specific areas should be provided by the Contractors for sorting and to provide temporary storage areas (if required) for the sorted materials. The materials could be segregated according to the categories as shown below: - Excavated materials suitable for reuse in reclamation; - Excavated materials for delivery to PFRFs; - Surplus rock to be recycled into aggregates and other rock products in the Lam Tei Quarry; - Sediments for delivery to sea disposal; and - Non-inert C&D materials for delivery to landfills. The C&D materials should at least be segregated into inert and non-inert materials, in which the inert portion could be reused and recycled in the reclamation as far as practicable before delivery to PFRFs. While opportunities for reusing the non-inert portion should be investigated before disposal of at designated landfills.




REV2 19

F. SYSTEM FOR ON-SITE SORTING OF C&D MATERIALS 工地內分類系統工地內分類系統工地內分類系統

工地內分類系統

The wastes generated from the construction activities contain a large amount of inert granular materials. Since disposal of the inert granular waste at landfills will not be permitted, therefore, it is necessary to sort them out from the construction waste stream. Waste can be sorted on-site in accordance with Section 8.6.11 of Waste Management of EIA Report No. AEIAR-173/2013. The contractor may chose the appropriate sorting method depending on the site space available, site layout, cost of refuse areas, labour available, the time required and site safety.

Section 8.6.11 of Waste Management of EIA Report No. AEIAR-173/2013

Concerning the necessity of maximising reuse for the Project, it is paramount for sorting to be performed to recover the inert materials, reusable and recyclable materials before disposal off-site. All surplus C&D materials arising from or in connection with the works shall become the property of the Contractor when it is removed unless otherwise stated. The Contractor will be responsible for devising a system to work for sorting of C&D materials and promptly removing all sorted and processed materials arising from the construction activities. The system should be included in the EMP, identifying the source of generation, estimated quantity, arrangement for sorting, collection, temporary storage areas (if any) and frequency of collection by recycling Contractors or frequency of off-site removal.

Alternatively separation of waste can be done on construction sites if the site conditions are suitable. Either one of the 2 schemes of separation of waste may be used.

• Centralized Separation on Site Under this scheme construction wastes will be collected and separated at a centralized area on site. This is probably situated at the ground level near the outlet of the refuse chute is there is any. Some precautions are necessary to ensure health and safety of the workers. For example, the provision of shelter to the waste collection area to prevent injury to workers caused by falling objects, and prevention of dusting by using water spray.

• Distribution Separation at the Work Places On some construction sites it might be easier and more convenient to sort construction wastes at the work places especially in case of limited site space on the ground level. If it is done daily, the condition of the work places would also be improved. Separate containers should be provided, probably on the ground level, to collect the sorted wastes for latter removal from site.

Scheme It is preferably to adopt the second scheme - Distribution Separation at the Work Places. Location

(1) Chemical Waste (i) Handling

• Chemical waste should be packed and held in containers of suitable design and construction so as to prevent leakage, spillage or escape of the contents under normal conditions of handling, storage and transport

• When packing a container with liquid chemical waste, sufficient ullage (air space) should be allowed to ensure that neither leakage nor permanent distortion of the container occurs as a result of liquid expansion caused by changes in temperature or other physical conditions which are likely to occur under normal conditions of handling, storage and transport. Generally 100 mm air space should be allowed between the top of the container and the level of the liquid contents

• In general, it is desirable to adopt a few common types in order to facilitate handling and transport by all parties concerned

• MH-INJO should ensure that the information contained on the label is accurate and sufficient so as to enable proper and safe handling, storage and transport of the chemical waste

(ii) Collection WING LEE will visit EPD’s website “epic.epd.gov.hk/ca/uid/waste_chemical/p/1” to make appoint with

the Chemical Waste Collector for following Waste Category available (as at 12 Mar 2004)

• Asbestos Waste (including Vehicle Brake/Clutch Linings)

• Asbestos-containing Vehicle Brake/Clutch Linings

• Dangerous Drugs, Poisons and Antibiotics

• Earth Material containing Heavy Metals/Mineral Oils

• General Chemical Waste

• Paint Waste

• Photofinishing Waste

• Sludge or Resin containing Heavy Metals/Solvents

• Spent Copper Etchant

• Spent Dangerous Goods, Category 5

• Spent Fluid containing Polychlorinated Biphenyls

• Spent Halogenated Organic Solvents/Compounds

• Spent Lubricating Oil Bottle and Spent Oil Filter

• Spent Mercury Lamp

• Spent Non-Halogenated Organic Solvents/Compounds

• Spent Plating Solution and Associated Waste

• Tannery Offcut Waste containing Chromium

• Waste Battery

• Waste Lubricating Oil/Waste Mineral Oil

• Waste Mineral Oil from Vessels (commonly known as MARPOL oily waste)

• Waste Transformer Oil (not containing Polychlorinated Biphenyls) In line with the progress, if there are chemical wastes to be generated on the Site, WING LEE will include the method statements and risk assessments recommended by the EPD licensed chemical waste collectors giving details on the nature of the chemicals, details and method of storage (e.g. Type, size and materials used for the container), as well as the proposed collection and disposal arrangement, etc.




REV2 21

(iii) Storage WING LEE should provide a suitable area for temporary storage of chemical waste. The storage area

should be located close to the source of waste generation, preferably within the site of the waste producer to minimise waste handling and to facilitate management control.

• The storage area should be used for chemical waste storage only

• Adequate ventilation should be allowed

• There should not be any connection to any surface water drains or foul sewers

• Adequate space should be allowed within the storage area for container handling by workers. In situations where large containers (e.g. 210 litres drums) are stored, space should be allowed for the manoeuvering of a trolley or other lifting devices

• It should be provided with a roof or similar covering designed to prevent rain and reduce heat from sunlight. Where flooding of the area is likely, the floor area should be raised, for example by adopting a raised platform design.

• The storage area should be kept secured with an appropriate door/gate and locked at all time

• The storage area should be kept clean and dry

• The storage area should have an impermeable floor or surface made of suitable materials for the storage of containers of liquid chemical waste. An impermeable layer will prevent infiltration of liquid into the floor in case of leakage or spillage.

• Where containers of liquid chemical waste are stored, the area should be designed to contain the content of the largest container intended to be stored or 20% of the total quantity of the chemical waste stored, whichever is the greater. The height of such retention structure should not exceed 200 mm to allow convenient manual or mechanical lifting and handling of containers

• Containers of incompatible chemical waste must not be stored together where potentially dangerous consequence may result in the event of contact between the wastes. Wastes that are incompatible generally include those that will react with each other

− Violently and dangerously − With evolution of substantial heat or causing combustion − to produce flammable, poisonous or harmful gases or − to produce toxic, corrosive or unstable products.

Incompatibles Hazards Upon Mixing

Cyanides Acids, Non-oxidizing

Generation of Hydrogen Cyanide, Inhalation of a small amount of the gas may be fatal

Hypochlorites Acids, Non-oxidizing

Generation of Chlorine. Inhalation may be fatal

Strong Acids Strong Alkalis May react explosively with generation of heat

Ammonia Salts Strong Alkalis

Generation of Ammonia, causing irritation of eyes & respiratory tracts on inhalation

Oxidizing Agents Reducing Agents

May react violently & explosively with generation of heat

• The stacking of containers of chemical wastes is allowed provided that - (a) the enclosure walls or partitions of the storage area are constructed out of an impermeable

material; (b) the stacks of containers are made secure so as to prevent their falling down; and (c) containers are stacked with each of them in the normal upright position and can be readily

moved when full.

As a general rule, the maximum height of a stack should be limited to 2.5 metres.

(iv) Disposal

Under CAP 354C Waste Disposal (Chemical Waste)(General) Regulation 《廢物處置(化學廢物)(一般)規例》,

any person produces chemical waste or causes it to be produced should register with the Environmental Protection Department as a chemical waste producer. (WING LEE Ref. No. TE20040920-001 dated 10 Nov 2004). WING LEE must engage a licensed chemical waste collector to collect the chemical waste for proper disposal. WING LEE is also required to comply with the requirements of the Code of Practice on the Packing, Labelling and Storage of Chemical Wastes and filling out of trip tickets. Chemical waste should be disposed of at licensed chemical waste disposal facilities (such as Chemical Waste Treatment Centre).

Sorting and segregating are important to recover waste for reuse and recycling.

• To facilitate sorting, a specific area should be allocated for on-site sorting of waste while suitable containers should be provided to temporarily store the sorted materials.

• If small area of the site limits detailed sorting, waste material should at least be separated into inert and non-inert portion. "Disposal Outlet" of chemical waste should refer to Disposal Facilities where the chemical waste will be delivered to the Chemical Waste Treatment Centre on Tsing Yi.

K. PERFORMANCE MONITORING 成績監察成績監察成績監察

成績監察

(1) Material & Waste Audit

The estimation of C&D materials generated from the construction activities is based on the practice and experience of the company. The wastage level should be compared with the norm, i.e. the average performance of the industry. More importantly. material and waste audit should be carried out in order to identify areas that can be improved in the progress of projects. The concepts of material and waste audit are as follows:

• Record the amount of materials employed on construction sites.

• Record the quantities of waste that have been removed for disposal and the related cost.

• With the data available, monitor the material wastage level periodically by comparing the amount of materials used with the corresponding quantities of work done.

• Investigate the causes of material wastage.

• Evaluate the effectiveness of corrective measures.

• Establish a company standard of material wastage level.

• Recommend preventative measures to reduce material wastage level.
