1.6              Regulations and Guidelines

1.6.1       During the course of the Contract, it is anticipated that various types of waste will be generated.  Each distinct waste type will require a different approach for the effective management and disposal as stipulated in the applicable legislation and guidelines.

Statutory Requirements

1.6.2       The following legislation relates to the handling, treatment and disposal of waste in Hong Kong:

l  The Waste Disposal (Amendment) Ordinance (WDO) (Cap 354). 

l  The Waste Disposal (Chemical Waste) (General) Regulation (Cap 354C). 

l  The Waste Disposal (Charges for Disposal of Construction Waste) Regulation. (Cap 354N). 

l  The Land (Miscellaneous Provisions) Ordinance (Cap 28).

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

l  Summary Offences Ordinance (Cap 228).

l  Other relevant regulations.

1.6.3       The WDO prohibits the unauthorized disposal of waste.  Construction waste is not directly defined in the WDO, but is considered to fall within the category of trade waste.  Under the WDO, wastes can only be disposed of at sites licensed by the Environmental Protection Department (EPD).

1.6.4       Under the WDO and the Charging Regulation, wastes can only be disposed of at designated waste disposal facilities that are licensed by the EPD.  For construction work with a value of more than HK$1M, the main contractor is required to establish a billing account at the EPD before transporting the construction waste to the designated waste disposal facilities (e.g. landfill, public fill etc.).  The vessels for delivering construction waste to a public fill reception facility would need prior approval from EPD.  Breach of these regulations can lead to a fine and/or imprisonment.

1.6.5       Under the  Waste  Disposal (Chemical Waste) (General) Regulation all producers of chemical wastes (including asbestos) must register with the EPD and treat their wastes either utilizing on-site plant licensed by the EPD, or arranging for a licensed collector transport the wastes to an appropriately licensed facility.  The regulation also prescribes the storage facilities to be provided on site, including labelling and warning signs, and requires the preparation of written procedures and training to deal with emergencies such as spillages, leakages, or accidents arising from the storage of chemical wastes.

1.6.6       The current policy related to the dumping of construction and demolition (C&D) material is documented in the Works Branch Technical Circular No. 2/93, Public Dumps.  C&D materials that are wholly inert, namely public fill, should not be disposed of at landfill, but should be taken to public filling areas, which usually form part of reclamation schemes.

1.6.7       The Land (Miscellaneous Provisions) Ordinance requires that dumping licenses be obtained by individuals or companies who deliver public fill to public filling areas.  The Civil Engineering & Development Department (CEDD) issues the licenses under delegated powers from the Director of Lands.

1.6.8       The Public Cleansing and Prevention of Nuisances By-Laws provide further controls on the illegal tipping of wastes on unauthorized (unlicensed) sites.

1.6.9       The Contractor is required to obtain all necessary permits and licenses under these ordinances including, but not limited to:

l  Chemical waste permits/licenses under the Waste Disposal Ordinance (Cap 354).

l  Public Dumping License under the Land (Miscellaneous Provisions) Ordinance (Cap 28).

                                    Table 1: Hierarchy/Programme of Waste Management

Waste Management Option/Programme

Required Actions

Avoidance / Reduction / Minimization

Avoid the generation of excessive waste by planning and scheduling material deliveries.

Minimize the amount of waste generated through careful planning and design, before commencing the contract.

 

Re-use

Where appropriate and practicable, construction materials such as timber formwork, metal, etc, and any spoil generated during excavation work should be re-used onsite.

 

Recovery and Recycling

Recyclable construction materials such as plastics and metal will be recovered, sorted and stored onsite in containers.  The containers will be transported off site for recycling at an approved facility.

Regularly serviced, covered recycling containers will be provided for the use of the onsite workforce.

 

Treatment and Disposal

All waste removed from the site requiring treatment and/or disposal will be transported to an approved facility.

 

 

3.1.2       To achieve waste reduction, environmentally responsible purchasing would involve the introduction of practices that discourage unnecessary purchases and encourage the purchase of products or materials that can be found locally, that have reduced packaging or recyclable packaging, increased durability and materials with recycled content, such as, recycled paper, steel, concrete and other raw construction materials.

3.1.3       Waste minimization is best achieved through the use of careful planning, design and close supervision.  It is expected that, following good waste management practices on site will result in a reduction of the amount waste being generated.  To minimize the wastage of raw materials that are delivered to the site, good management, estimation and planning techniques will be required.

3.2              Waste Reduction Targets

3.2.1       In order to determine whether the waste management procedures used by Leighton V Chun Wo Joint Venture are effective, the following specific targets will be implemented onsite in an effort to reduce the generation of waste materials, and thus minimize the amount of waste requiring disposal at landfill:

l  All excavated material will be sorted on site to recover the inert portion of construction and demolition debris materials, such as hard rock, soil and broken concrete, for subsequent re-use on site or disposal to designated outlets.

l  Recover and store all metallic waste (e.g. scrap metal) for subsequent collection by a recycling contractor and recycling at an approved facility.

l  Recover all cardboard and/or paper packaging (for plant, equipment and materials) will be stored in covered stockpiles (to keep dry and prevent contamination) for subsequent collection and recycling at an approved facility.

l  All chemical waste that is generated on site (e.g. servicing of plant) will be stored for collection and disposal at an approved disposal facility.

l  All demolition debris will be sorted on site to recover broken concrete, reinforcement bars, mechanical and electrical fittings, hardware as well as other recyclable fittings for subsequent recycling at an approved facility.

l  To minimize the use of timber during construction, recyclable metal formwork and hoarding will be used where practicable.

3.3              On Site Sorting of Materials

3.3.1       Leighton V Chun Wo Joint Venture will designate suitable areas onsite for the storage, sorting and segregation of construction waste.  The areas that are designated by Leighton V Chun Wo Joint Venture will be clearly defined with appropriate signage and barriers (or similar) and allow for easy access by workers and vehicles. The layout plan of proposed temporary storage and sorting area for C&D materials is shown in Appendix B. As the project progresses, it is anticipated that the designated areas will be reviewed depending upon construction program requirements.  The areas designated by Leighton V Chun Wo Joint Venture will be sufficient for the amounts of construction waste that are anticipated to be generated during the course of the contract.  Table 2 below shows the actions that will be taken for each type of construction waste generated onsite.

4             Waste Management Procedure

4.1              General

4.1.1       The waste that is generated during the construction process will be disposed of at designated disposal facilities.  Monthly summaries of the amount of waste material disposed of offsite will be provided to the Engineers Representative (ER) in the form of a Waste Flow Table (WFT).  The summaries will indicate the estimated quantities of waste removed the types of materials removed and the corresponding disposal ground in the WFT.

4.1.2       The quantities of C&D material disposed of will be recorded under the barcode TTS by using the CHIT / DDF (for disposal of C&D Materials at Disposal Grounds (Other than Prescribed Facilities) as designated in the Contract or as Directed by the ER, or Alternative Disposal Grounds Proposed by the Contractor and Approved by the ER).  In addition, a completed CHIT will also be presented to the receiving facility as part of the system for the disposal charging scheme which became officially effective in January 2006.  Waste transaction records could be obtained either from the waste disposal facilities directly, or retrieved from the EPD bill statement each month.

4.2              Waste Acceptance Criteria for Government Disposal Facilities

4.2.1       Leighton V Chun Wo Joint Venture will comply with the acceptance criteria laid down by the operators of the corresponding fill bank(s) and landfill(s), as outlined below:

Acceptance Criteria for Fill Banks (Tuen Mun Area 38 Fill Bank)

4.2.2       The truck drivers should bear a duly signed CHIT / a duly completed, signed and stamped DDF (for approved alternative disposal grounds).  The dump truck should also have a valid Dumping Licence issued by CEDD.  Dump trucks without valid Dumping Licences will be rejected.

4.2.3       The inert C&D materials to be delivered to the fill bank(s) should be in accordance with the conditions stipulated in the Dumping Licence.  Any over-sized inert C&D materials will be broken down to less than 250mm in size so as to facilitate its reuse by other reclamation or earth-filling projects.  The C&D materials to be disposed should consist entirely of inert construction waste (i.e. 100% inert construction waste).

4.2.4       Recyclable materials such as metal, paper, plastics and milled bituminous materials etc., which have been sorted on the site for the purposes of recycling, shall not be considered as C&D materials and should be delivered to a proper recycling outlet for processing. 

Acceptance Criteria for NENT Landfill

4.2.5       The truck drivers should bear a duly signed CHIT.  The dump truck should also have a valid Dumping License issued by CEDD.  Dump trucks without valid Dumping Licenses will be rejected.

4.2.6       The non-inert C&D waste to be delivered to the landfills should be in accordance with the conditions stipulated in the Dumping License. 

4.2.7       Construction waste containing not more than 50% by weight of inert C&D waste (Gazette Notice G.N. 4274 published on 16 June 2008).

4.2.8       For a load of C&D waste not consisting entirely of bamboo, plywood or timber delivered by a vehicle, the weight of the waste divided by the permitted gross vehicle weight of the vehicle must not greater than 0.25 for goods vehicle with demountable skip and 0.2 for other types of vehicle (Gazette Notice G.N. 4274 published on 16 June 2008).

4.2.9       Mixed C&D materials should be sorted at source to reduce the inert content as far as practicable to meet the above criteria before they are delivered to landfills.

4.2.10    C&D waste delivered for landfill disposal should contain no free water and the liquid content will not exceed 70% by weight.

4.2.11    At least one (1) weeks notice, including contractors name and contact details etc, will be submitted to the EPD before starting to deliver the C&D waste to the landfills.  EPD will be informed of any subsequent change to the disposal programme.

4.3              Procedures of the Trip Ticket System

4.3.1       Leighton V Chun Wo Joint Venture will implement a TTS to track the disposal of C&D materials.  Under the TTS, each truck carrying C&D materials leaving the Site for a disposal facility will be accompanied by a duly completed and stamped CHIT / DDF.  The C&D materials must be disposed of at the disposal grounds as stipulated in the DDF.  The TTS will be executed according to the following procedures:

4.3.2       The Foremen will arrange the C&D waste to be segregated on site and also check the total actual amount of cumulated C&D waste after the completion of the particular works in the working area.

4.3.3       The C&D waste will be sorted and stored separately into different storage areas.

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

4.3.5       For each truckload of C&D material leaving the working area to the designated fill banks / landfills, the truck driver must bear a duly completed, signed and stamped CHIT. A Notification to Truck Driver (attached in Appendix C) will be given to truck drivers to remind them the proper disposal procedures. 

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

4.3.7       The truck driver will present the CHIT at the weighbridge.  If the vehicle load is accepted, the CHIT is deemed to be used and the weight would be recorded on the Transaction Record Slip.

4.3.8       If the truck driver is instructed by the reception facility operator to go to the sorting facility, the driver will need return back to the site and report to the Foremen.  No driver is allowed to go to sorting facility without Foremen permission or instruction.

4.3.9       The truck driver will then return the transaction receipt and the stamped CHIT / DDF to  Leighton V Chun Wo Joint Venture as soon as possible.  All CHIT / DDFs are to be return to the EO.

4.3.10    Leighton V Chun Wo Joint Venture will maintain a daily record summary (DRS) of disposal of C&D material from the Site including details of the C&D waste, the truck number, departure time, etc.  This record will be checked against the ER records as soon as possible and the ER will be notified immediately in case any discrepancy is noted.

4.3.11    Part 1 of the DRS will be completed in duplicate and a copy should be kept by the ER.

4.3.12    For disposal at government disposal facilities, Leighton V Chun Wo Joint Venture will check the information recorded in the DRS against the disposal records on CEDDs or the EPDs website (see below).

l  http:www.cedd.gov.hk/eng/services/tripticket/index.html.

l  http://www.epd.gov.hk/epd/misc/cdm/trip.html

4.3.13    Part 2 of the DRS will be completed and submit to the ER within 1 working day after the records are posted at the EPD web-site.

4.3.14    Where an irregularity is observed or where requested by the ER under special circumstances (e.g. a CHIT / DDF has been issued but there is no disposal record at the disposal ground), Leighton V Chun Wo Joint Venture will submit to the ER within 5 working days after the recorded date of disposal the supporting evidence such as duly stamped CHIT / DDF and/or the Transaction Record Slip (where relevant) to confirm proper completion of the delivery trips in question, or within 2 working days after the ER has requested for such evidence, whichever is later. A fax copy of the CHIT / DDF or Transaction Record Slip is acceptable, unless otherwise directed by the ER.

4.4              Measures to be implemented During Transportation of Wastes to Avoid Leakage of Wastes onto Public Areas

4.4.1       All trucks to transport waste from the site will be in good working condition and will be equipped with mechanical covers (or similar) to prevent leakage of waste onto public areas.  In addition to the cover, to further minimize the leaking of waste from the trucks, trucks should not be filled higher than the trail board.
