The Waste Management Plan (WMP) has been developed in
accordance with clause 2.10 of Environmental Permit EP-353/2009/C and clause
2.10 of Environmental Permit EP-354/2009/A and G.S. 25.25 of the Particular
Specification for the Highways Department Contract namely Contract No.
HY/2010/02 Hong Kong Zhuhai Macao Bridge Hong Kong
Boundary Crossing Facilities ¡VReclamation Works (hereinafter the Contract)
This Waste Management Plan (WMP) aims to describe the
arrangements for avoidance, minimization, handling, reuse, recovery and
recycling, storage, transportation, collection, treatment and disposal of
different categories of waste to be generated from the construction activities
of this project. This WMP includes the recommended mitigations measures on
waste management as contained as stipulated in EIA report and EM&A Manual.
The main objectives of the WMP include:
i)
providing
reference to the waste management requirements, both statutory and
non-statutory;
ii)
clarifying
the responsibilities of each party on waste management and the personnel within
the Contractor¡¦s management;
iii)
establishing the waste management procedures for
avoidance, minimization, material reuse/recovery/recycling, collection, transportation,
storage and disposal of wastes generated from the activities.
An Environmental Management Policy is established to
demonstrate the Company¡¦s commitment in improving environmental
performance. It aims to communicate
The policy will be reviewed by relevant parties
periodically and will be displayed on notice boards in languages suitable for
the nationality for the workforce.
The Environmental Policy Statement, together with the
Environmental Objectives and Targets, are listed below:
To demonstrate the Project Team¡¦s commitment on the continual
improvement of our waste management performance, an Environmental Management
Policy includes the waste management has been established. It aims to communicate
The hierarchy is illustrated below. It attempts to evaluate waste management practices and selects the best practical option since conceptually it makes sense to avoid producing a waste rather than developing extensive treatment schemes. Good planning and site management practices also help minimizing over ordering or misuse of construction materials. The overall objective is to reduce and minimize the amount of wastes generated, hence reducing the costs of waste handling and disposal.

General
1.4.1 Various types of wastes would be generated during the course of the Project and
each waste types requires different
approach for management and disposal as stipulated in the waste legislation and
guidelines. The relevant statutory
and non-statutory requirements regarding waste management are summarized in the
sections below.
Statutory
Requirements
1.4.2 The following legislation relates to the handling, treatment and disposal of wastes in
Hong Kong,
and would be observed with regard to all wastes generated and requiring
disposal, where applicable:
l the Waste Disposal Ordinance (Cap 354)
l the Waste Disposal (Chemical Waste) (General) Regulation (Cap 354)
l the Waste Disposal (Charges for Disposal of Construction Waste) Regulation
l the Land (Miscellaneous Provisions) Ordinance (Cap 28)
l the Dumping at Sea Ordinance (Cap 466)
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
1.4.3 The Waste Disposal Ordinance (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 EPD.
1.4.4 Under the Waste Disposal (Chemical Waste) (General) Regulation all producers of chemical wastes (including asbestos) must register with EPD and treat their wastes either utilizing on-site plant licensed by EPD, or arranging for a licensed collector to take the wastes to a licensed facility. The regulation also prescribes the storage facilities to be provided on site, including labeling 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.
1.4.5 The current policy related to the
dumping of C&D material is documented in the Works Branch Technical Circular No. 2/93,
¡¥Public Dumps¡¦. Construction and demolition materials that are wholly inert, namely public fill, should
not be disposed of to landfill, but taken to public filling areas, which usually form part of reclamation
schemes. The Land (Miscellaneous Provisions) Ordinance requires that dumping licences be obtained by individuals or companies who
deliver public fill to public filling areas. The Civil Engineering &
Development Department (CEDD) issues the licences
under delegated powers from the Director of Lands.
1.4.6 Under the WDO and the Charging
Regulation, wastes can only be disposed of at designated waste disposal
facilities licensed by EPD. For
construction work with a value of more than HK$1M, the main contractor is
required to establish a billing account at 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 public fill reception facility would need
prior approval from EPD. Breach of
these regulations can lead to a fine and/or imprisonment.
1.4.7 The Public Cleansing and Prevention of Nuisances By-Laws provide further controls on the illegal tipping of wastes on unauthorized (unlicensed) sites.
1.4.8 The Contractor would 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); and
Non-statutory Regulations

Waste Policy Principles
Refer to hierarchy abovementioned in Section 1, a further explanation of the hierarchy of waste management on site is detailed below.
3.1.1 Key to waste management is to reduce the amount of waste generated from the
work site. Waste management options would be exercised in accordance with the hierarchy stipulated in the following table:
Avoidance and Minimization |
Avoid and minimize waste through careful planning and design works. |
Reuse |
Reuse construction waste such as excavated material, used wooden plants and ferric materials. |
Recovery and Recycle |
Undertake on-site or off-site waste recycling |
Treatment and Disposal |
Properly treat and dispose of waste in accordance with legislative requirements, guidelines and good practices. |
Table 2: Hierarchy of Waste Management
3.1.2 In the context of waste reduction, environmentally responsible purchasing would involve the introduction of practices that discourage unnecessary purchases and encourage the purchase of products with reduced packaging, increased durability and with high recycled content. For example, recycled paper, steel and other raw construction materials.
3.1.3 Waste minimization is best achieved through careful planning, design and supervision. Good management practices would reduce and prevent large amount of waste generated. Raw materials would be managed from the first instance before they are ordered and delivered to the site. Good estimation and planning would minimize the amount of raw materials wasted. The generation of waste would be controlled at source.
Specific
measures will be implemented to reduce the generation of waste materials, and
thus minimize the amount of waste disposal to landfills. The measures will include:
recover
all metallic waste for recycling;
recover
all cardboard and paper packaging, and properly stockpile them in dry and
covered condition to prevent cross contamination;
use of the materials (such
as formworks and hoardings) in the construction would be calculated before
purchasing in order to minimize waste generation.
use of metal formworks and
hoardings, and they would be recycled after demolition on site as far as it can
before disposal.
On site
sorting facilities for imported material would be established in TKO Area
137. Please refer to Appendix A for the layout plan of
sorting facility on site.
There is
a soil heap stockpiled at WA4 works area to be reused for reclamation filling. The soil heap would be checked by survey
about the volume of quantities and submitted to the Engineer for their
record. Upon filling, we will use
barge for the transportation of the fill and each barge would be measured of
the quantities of fill by trip ticket system for monitoring of record. The total barges used for the stockpiled
soil would be checked against the survey record for monitoring of the transfer
of the soil heap.
For
imported fill materials, CHEC will seek the Engineer¡¦s Representative approval
prior to acceptance of such materials from other site(s). To ensure that the fill materials are
imported from the approved site(s) and to avoid illegal disposal of such
materials, specific recording and monitoring system will be established for
each case and the system will be submitted to the Engineer¡¦s Representative for
approval.
For
control of the percentage of fine content in filling material, laboratory test
for sample taken would be conducted for sieve analysis test by Government
Laboratory to confirm compliance.
The fine content test would be conducted earlier at the source site to
confirm its compliance with the Contract requirement and the test results would
be provided for verification by the
Engineer Representative and the IEC before the fill materials are allowed to
ship to our site for filling.
The
target fine content of the sand fill in the WMP shall not exceed 5% when
finally placed in the Works. For
the fine content of the public fill material the target maximum level would be
below 25%, which is to be controlled by prior testing at the source site and
the test result would be verified by Engineer Representative and IEC before
transporting to the site for filling.
According
to our strategic planning, the delivery of public fill for earthwork above
+2.5mPD will be commenced in Month11. The average required daily handling rate
of public fill will be around 17,5000 m3 of Type A,
Type B and surcharge fill majorly occurring in Month 11 to Month 30. The
proposed sorting facilities together with barging points
facilities have been designed to meet this peak production. In addition, CHEC
will secure sufficient marine resources for handling the peak of consumption of
public fill in HKBCF site.
The
public fill material will be collected from designated barging points as
indicated in working drawing No: 211036/SL/1005 attached in Appendix G. CHEC will utilize our barges to collect
the public fill material from those barging points as much as possible in order
to maximize the usage of public fill material for this reclamation project. The
features of public fill sorting plant layout plan & sorting facility
design are presented
in Appendix A.
Owing to
the available sorting facilities, the supply quantities of public fill in TKO
Area 137 will be constant and sorted to the most suitable for the reclamation
purpose. However, the daily output capacity of the sorting facilities are
around 45,000 tonne (Equivalent to 25,000 m3) which is only provide
approximately 40% of public fill for the earthworks above +2.5mPD during the
peak supply month. Therefore, the remaining 60% of public fill will be
collected from other barging points such as TM38, WA4 and MTRC which become the
major sources of the public fill material. In fact, the quantities of public
fill collection in these barging points may be fluctuated depending on the
output rate of the barging point operators and the relevant project progress.
In order to overcome the risk of fluctuation, we will firstly deploy our
vessels as much as possible to collect the public fill available from these
barging points and the remaining quantities will be collected from TKO Area
137. Moreover, CHEC will closely coordinate with the contractors of the barging
points regarding the schedule of barges for collecting public fill and the site
conditions of the loading facilities to ensure smooth progress of loading and
transporting public fill to the Site and that sufficient barges are provided. A
trial will be conducted for collection of public fill in different barging
points to ensure the navigation and mooring condition such that suitable barges
will be provided for smooth logistic operation.
3.3.5 Logistics
Relating to Collection, Sorting, Transportation and Stockpiling of Public Fill
for filling works above +2.5mPD
In this project,
the major usage of public fill material will be Type B and surcharge fill for
the earthworks above +2.5mPD of which the total handling capacity is
approximately 10.3 Million m3 in taking into account the settlement. In order
to achieve the timely completion and maximization for usage of public fill
material, an adequate logistic planning is crucial to handle such huge amount
of filling material. CHEC will deploy both marine and land-based plant by using
the most effective and efficient ways for collection, sorting, transportation
and stockpiling of public fill for filling works above +2.5mPD so as to reach
the goal of the project. According to our planning, the target delivery
schedule for handling of public fill relating to below and above +2.5mPD will
range from Month 11 to 30 and the average required daily filling rate of public
fill is 17,500 m3 from Month 11 to Month 30. The overall quantities of public
fill to be collected and handled for the earthworks below and above +2.5mPD is
tabulated below:

Delivery Programme for Collection, Sorting and Transportation of
Public Fill Material
The
delivery arrangement of public fill material including the operation of sorting
facilities and the collection, sorting, transportation and stockpile for
earthworks above+2.5mPD will be same as the underwater filling works up to
+2.5mPD except for unloading and placing filling works. In order to achieve the
delivery programme as aforesaid above, CHEC will
deploy 19 nos. material barges with the total delivery capacity over 43,280m3
per day which enable to collect the scheduled maximum daily output rate at
17,500m3 from different barging points and transport to site for earthworks
above+2.5mPD. The daily delivery capacity of our planned fleet is scheduled in

In the
above table, the overall logistic arrangements for barges have sufficient
flexibility and taking into consideration with appropriate contingency plan and
general holiday. The plant will be reviewed from time to time to suit the
actual site condition and also extra plant will be deployed on site when
required. In considering the combination effects for delivery of public fill
material both underwater fill below+2.5mPD and earthworks above+2.5mPD, the
maximum scheduled daily filling rate will require 17,500 m3 where filling for
Portion C1b, E1 & E2 are concurrently executed. Our deployment of barge
fleets will be well sufficient to fulfill such daily requirements.
Details
of the filling rate, please refers to the Appendix
B.
The quantities of disposal C&D materials will be recorded under the barcode trip ticket system by using the ¡§C&D Material Disposal Delivery Form¡¨. In addition, the filled ¡§CHIT¡¨ will also be presented to the landfill site as part of the system for the disposal charging scheme which had already been officially effective in January 2006. Waste transaction records could be obtained either in the waste disposal facilities right after the transaction or retrieved from the EPD bill statement each month.

the designated landfills after the DDF has been received from the Engineer¡¦s Representative.
For every 14
days or one truckload collected, the stored inert C&D
waste in the temporary holding area will be transferred to the
designated fill banks after the DDF has been received from the Engineer¡¦s Representative.
If the sorted C&D waste is more than 1/3 of
truckload, then the Foreman will arrange disposal of the C&D waste to designated fill banks /
landfills after the Disposal Delivery Form (DDF) has been received from the Engineer¡¦s Representative.
For each truckload of
C&D materials leaving the working area /
temporary holding area to the designated fill banks / landfills, the truck driver must bear a duly completed, signed and stamped
Disposal Delivery Form (DDF) and a duly signed CHIT.
The truck will proceed to the disposal ground as stipulated in the
DDF. The truck driver will present
the DDF and the CHIT 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 DDF.
The truck driver will
present the CHIT at the in-weightbridge
officially. If the vehicle load is
accepted, the CHIT is deemed to be used and the in-weight would be recorded on
the ¡§Transaction Record Slip¡¨.
If the truck driver was 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 Superintendent / Senior
Foreman / Foremen. No driver is allowed to go to sorting
facility without Superintendent / Senior Foreman / Foremen permission or instruction.
The truck driver will then return the transaction receipt and the
stamped DDF to CHEC as soon as possible. All DDFs are to
be return to the Environmental Officer.
CHEC will maintain a daily record disposal of C&D materials from the
Site including details of the C&D waste, the truck number, departure time, etc,
and should check against the Engineer¡¦s
Representative records as soon as possible and notify the Engineer¡¦s Representative in case any discrepancy is
noted.
A daily record of disposal
of C&D materials from the Site will be maintained, the record includes the
details of the C&D materials, the truck number, departure time, etc., using
the Daily Record Summary (DRS).
The duly completed Part 1
of the DRS would be submitted promptly to the Engineer¡¦s Representative by 1:00pm of the working
day following the date of disposal.
For disposal at government disposal facilities, CHEC will check the
information recorded in the DRS against the disposal records in CEDD¡¦s website
(http:www.cedd.gov.hk/eng/services/trip ticket/index.html) or EPD¡¦s website
(http://www.epd.gov.hk/epd/misc/cdm/trip.htm) and complete Part 2 of the DRS
for submission to the Engineer¡¦s
Representative within 3 working days after the day of disposal, or a later day if the
information in CEDD¡¦s / EPD¡¦s website is not yet available within 3 working
days.
Where an irregularity is observed or
where requested by the Engineer¡¦s
Representative
under special circumstances (e.g. a DDF has been issued but there is no
disposal record at the designated disposal facilities), CHEC will submit to the
Engineer¡¦s Representative within 5
working days after the recorded date of disposal the supporting evidence such
as duly stamped DDF and/or the transaction receipt (where relevant) to confirm
proper completion of the delivery trips in question, or within 2 working days
after the Engineer¡¦s Representative has
requested for such evidence, whichever is later. A fax copy of the DDF and transaction
receipt is acceptable, unless otherwise directed by the Engineer. CHEC will maintain all records on the
DDF for at least one year or other period as may be directed by the Engineer¡¦s Representative.
The characteristic of this
Project is to import public fill and sand by barges onto the site for
filling. Land route is not accessible
to the reclamation site for filling works.
The control of barges coming to the site
for filling works will be controlled by the implementation of trip ticket
system.
The public fill would be from
the source sites of Fill Bank 137 at Tseung Kwan O
managed by CEDD and the MTRC projects currently under construction. A trip ticket system will be agreed with
the ER, CEDD and MTRC for the filling record such as the date and time of the
barge leaving the site and the quantities of fill checked and agreed by ER and
CEDD/MTRC for endorsing the tickets.
The copies of tickets would be issued to the Engineer daily for their
record and a summary of the record would be issued to the Engineer monthly for
checking and verification.
The public fill at source site
must be tested to confirm compliance with the Contract Specifications such as
the fine contents of the public fill etc. Before they are
allowed to leave the source site to our work site for filling work. Test sample of public fill and sand
specimen at the source site must be submitted to the Engineer for record.
All of the dump trucks used would be equipped with mechanical covers in which
maintained in a good condition.
In order to minimize the leaking of material from the dump trucks, no
material should be stored higher than the trail board.
Deposited silt and wastes on all dump trucks¡¦ wheels and bodies should
be properly washed off by wheel washing facilities before leaving the
constructions sites.
CHEC will provide wheel washing facilities on site at the site entrance.
Where
CHEC has identified a project that can be an alternative disposal ground, CHEC
will provide a detailed description of the alternative disposal ground,
including location, lot number (where appropriate) and location plan(s) to the
Engineer to request for his written approval.
Where the
alternative disposal ground is a private construction project, CHEC will submit
a letter from the Authorized Person of the development (as defined under the
Building Ordinance) to confirm that:
the C&D materials for use in the development is
acceptable;
the
use of land so formed by the C&D materials is in conformity with the
statutory town plan / lease conditions;
the Engineer¡¦s Representative are allowed to
enter the alternative ground to conduct inspection where necessary; and
the
estimated quantity and type of C&D materials to be used in the construction
works and the approximate delivery programme, together with the name, post and
specimen signature of the competent person to sign the DDF / internal trip
ticket stipulated in G.S. Clause 25.25(5)(a)(ii).
Where the
alternative disposal ground is a private land but not a construction site, CHEC
will submit a letter from the relevant authorities, such as the Lands
Department and Planning Department, to confirm that the suitability of the
alternative disposal ground in receiving the proposed amount of C&D
materials for use, and a written consent from the landowner.
Where the
alternative disposal ground is a government project, CHEC will submit written
consent from the project office of the alternative disposal ground to use the
C&D materials generated from the Site, and to confirm the estimated
quantity and type of C&D materials required and the approximate delivery programme.
A system
for transmitting disposal records from the alternative disposal ground will be
submitted to the Engineer¡¦s Representative for approval before disposal to the
alternative ground starts.
Chemical waste
that is produced, as defined by Schedule 1 of the Waste Disposal (Chemical
Waste) (General) Regulation, will be handled in accordance with the Code of
Practice on the Packaging, Labelling and Storage of
Chemical Wastes as follows:
Packaging
Chemical
waste will 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.
Containers
used for the storage of chemical wastes will:
¡P Be suitable for the substance they are holding, resistant to corrosion, maintained in a good condition, and securely closed;
¡P Have a capacity of less than 450 litres unless the specifications have been approved by the EPD; and
¡P Display a label in English and Chinese in accordance with instructions prescribed in Schedule 2 of the Regulations.
Labelling
Every
container of chemical waste will bear an appropriate label which will contain
the particulars details. The waste producer
will 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.
Storage
The
storage area will be specially constructed and bunded,
and located close to the source of waste generation.
The
storage area for chemical wastes will:
¡P Be clearly labelled and used solely for the storage of chemical waste;
¡P Be enclosed on at least 3 sides;
¡P Have an impermeable floor and bunding of sufficient capacity to accommodate 110% of the volume of the largest container or 20% of the total volume of waste stored in that area, whichever is the greatest;
¡P Have adequate ventilation;
¡P Be covered to prevent rainfall entering (water collected with the bund must be tested and disposed of as chemical waste); and
¡P Be arranged so that incompatible materials are adequately separated.
Before
reaching 80% capacity of the storage container, licensed waste collectors will
be employed to remove the chemical waste.
Transportation and Disposal
After the
chemical wastes have been packed, labelled, and
stored, the chemical wastes will be transported by licensed waste collectors
and disposed of at Chemical Waste Treatment Facility in Tsing
Yi or other approved facilities.
4.7.1
Handling the general refuse
Measures to be implemented
to encourage waste avoidance / minimization include:
Reducing the number of photos copies to a minimum and by copying on both
sides of paper for internal documents and external documents where appropriate;
Preventing over-ordering of office equipment and consumables;
Procuring green office equipment and consumables in terms of energy
efficiency, recycled content and durability, etc;
Deploying sufficient recycle bins in site offices to facilitate
collection of recyclables including wasted aluminum cans, plastics bottles and
papers;
Deploying sufficient collection bins with cover at convenient locations
at site to facilitate collection of non-recyclable for disposal at landfills;
General refuse generated from working vessels and barges can dispose the
waste into temporary waste collection point.
Working vessels for import fill or delivery should be handled by
themselves.
There will be waste receptacle on the working vessels for
collection. In the event that some
refuse are found on the sea, we will collect the refuse by worker on a regular
daily basis.
During the construction stage, peripheral temporary surface channels will be
constructed to collect surface runoff in the construction area for desilting before discharging into the adjacent waters. The
measures would apply to office areas of WA2, WA3 and WA4 only.
The temporary drainage
system during the construction phase will be formulated by the CHEC to match
works and construction programme.
For reclamation area there
will be no drainage system as the storm water is contained by the erected
seawall which is 1m higher than the formation level of +5.5mPD. Storm water will be soaked into the new reclaimed
soil ground.
For
office area of WA2, WA3 and WA4, the locations of which are shown in Appendix I, storm water is collected by surface channel and catchpit and further treated by settlement tank before
discharge into existing drainage system nearby. For sewage collection will be by holding
tank to be pumped out at regular interval for disposal. Handling of sewage in
terms sewage generated by human would be provided adequate chemical toilets for
collection.
Sufficient
numbers of chemical toilets for workers and frontier workforces were placed on
works area other than site offices such as WA2, WA3 and WA4.
The following types of waste would be generated from the works areas of WA2, WA3, WA4 and reclamation site.
l Site clearance waste from works areas WA2, WA3 and WA4.
l Excavated material from box culvert construction to be re-deposited into
reclamation area.
l Chemical waste from maintenance of plant and equipment
l General refuse form the workforce on site
l Soil heap stored at WA4 to be reused in reclamation area
l General refuse form the workforce on site
l Import sand for reclamation works.
l Import public fill for reclamation works
l Removal of surcharge of public fill and return to Fill Bank 137 at Tseung Kwan O )
The estimated amount of waste to be generated from the Contract is listed in the

The disposal of imported sorted public fill of 1,565,891 cu.m to Fill Bank 137 at Tseung Kwan O is due to the surcharge material which will be trimmed down from +11.5mPD to +5.5mPD level after the surcharge period is over as stated in the Contract Specifications. The soil is disposed off site via marine access using barges. Trip ticket system is used and signed by ER/CEDD for endorsement of the ticket for proper control.
We assume this project to have 500 site personnel at peak level and each person consumes a waste of 5L per day. For a period of 4 years the waste would be 3,650 cu.m total.
CHEC will either dispose the dredged sediment generated sediment from the Project within the steel cellular structures or to the re-deposition area on site (if the associated VEP application is permitted). Hence, no dredged sediment would be disposal off-site and no designated marine disposal ground being approved by government.
In order
to distinguish the waste generated from site, the waste is sorted into 3 colour receptacles would be provided on site at site areas
WA2 and WA4. Control measures would be devised to ensure that the recyclable
materials are delivered to a proper recycling outlet for processing, and to
avoid such materials being considered as C&D materials for the purposes of
the Contract.
All of the recyclable material would be collected by registered contractors.
Details
of these contractors were listed in the website of EPD as waste collectors and
recyclers, the information can be search via the hyperlinks as http://www.epd.gov.hk/epd/english/environmentinhk/waste/guide_ref/guide_ref_dwc.html
The relevant licensing legislation and licensing/control requirement is listed in Section 1 above.
There will be both inert C&D materials (comprising soil, broken rock and concrete, etc) and non-inert C&D materials generated under Contract No. HY/2010/02. With reference to the clause 25.25 of PS, the designated disposal grounds for inert and non-inert C&D materials are listed as follows:-
Inert C&D Materials:
Tuen Mun Area 38 Fill Bank and Tseung Kwan O 137 or other disposal outlets as directed by the Engineer
Non-inert C&D Materials:
West New Territories Landfill (WENT)
or Outlying Island Transfer Facilities.
Monthly
Summary for C&D material disposal off the Site will be provided to indicate
the estimate quantities, types of C&D materials and corresponding disposal
ground in Waste Flow Table (WFT).
Disposal
locations for inert C&D materials would be Tuen Mun Area 38 or Tseung Kwan O Area
137. The non-inert C&D materials would be disposed to WENT landfill or
Outlying Island Transfer Facilities.
For this
contract, there is no marine disposal requirement outside reclamation area. No
off-site designated marine disposal ground.
As the
reclamation site is by marine access only, there will not be installed wheel
washing bay for the reclaimed land.
Wheel washing facilities would be installed at works areas WA2, WA3 and
WA4 as these areas are land access for vehicles. The wheel washing facilities would be
cleaned at least twice daily.
CHEC will
write to all truck drivers whom he or his sub-contractor(s) has engaged for
removal of C&D materials from the Site and draw their attention to the
following particular points:
Each truck
carrying C&D materials leaving the Site for a disposal ground must bear a
duly completed and stamped DDF, irrespective of the location and nature of the
disposal ground;
The C&D materials
must be disposed of at the disposal ground as stipulated in the DDF; and
What constitute
and improper disposal and that the Public Fill Committee (PFC) will consider
revoking the Dumping Licence from the holder of the
offending trucks.
Truck drivers
must bear a valid Dumping Licence that he can apply
from the Civil Engineering and Development Department (CEDD)
The Flow Chart of the TTS and the notification
to truck drivers and the receipt form is attached in Appendix C and D respectively.
The Construction and Demolition Material Disposal Delivery Form (DDF) will be used for each and every vehicular trip transporting construction and demolition (C&D) material off site.
Prior to the vehicle leaving the site, the Engineer¡¦s Representative will insert the date, time of departure, vehicle licence plate number, designated public filling facility / landfill, and other information as required, and stamp the form. The Engineer¡¦s Representative will then retain the first strip of the form and pass the rest to CHEC¡¦s Representative. The form will be carried on board the vehicle at all times throughout the vehicular trip.
A comprehensive register of the DDF issued
will be maintained and available for inspection by the Engineer¡¦s Representative upon request. The
following records will be kept for monitoring of the DDF issued:-
Daily Record Summary (DRS) and the Waste Flow Table (WFT) should be completed and submitted to the Engineer¡¦s Representative for record. A sample of DRS and WFT, please refer to Appendix E and F respectively.
Record of the quantities of C&D materials
generated each month will be maintained using the monthly summary Waste flow Table
(WFT). CHEC will complete and submit the monthly summary WFT to the Engineer by
not later than the 15th day of each month follows the reporting month, or if it
is a General Holiday, the day following the General Holiday, or a later date as
agreed by the Engineer.
The estimated quantities of C&D materials to be
generated each year from the site will be summarised using the yearly summary
WFT. The WFT will be updated on a half-yearly basis and submit to the Project
Proponent by not later than 1st of June and December of each year, or if it is
a General Holiday, the day following the General Holiday, 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.
These summaries shall also be made available to ETL and IEC/ENPO
Specific trip ticket and records for internal transfer of C&D materials and imported fill materials will also be kept for monitoring whatever necessary.
For recyclable materials, CHEC¡¦s Representative will record the quantities of all the recyclable materials before removal off the Site by the recycling contractors, and include the details in the WFT for submission to the Engineer¡¦s Representative.
In order to ensure proper disposal of C&D
materials, enhancement measures to further improve the TTS recording system, a
video recording system shall be installed and disposal shall be checked against
survey record. Such video recording system used to monitor the vehicular exit /
entrance of the site.

a trip-ticket system for each works contract to ensure that the disposal of
C&D materials are properly documented and verified; ¡P Implement
an enhanced Waste Management Plan similar to ETWBTC (Works) No. 19/2005 ¡V
¡§Environmental Management on Construction Sites¡¨ to encourage on-site sorting
of C&D materials and to minimize their generation during the course of
construction; ¡P In
addition, disposal of the C&D materials onto any sensitive locations such
as agricultural lands, etc. should be avoided. The Contractor shall propose
the final disposal sites to the Project Proponent and get its approval before
implementation; and ¡P The surplus surcharge should be transferred to a

C&D Waste ¡P
Standard formwork or pre-fabrication should
be used as far as practicable in order to minimise
the arising of C&D materials. The use of more durable formwork or plastic
facing for the construction works should be considered. Use of wooden hoardings should not be used,
as in other projects. Metal
hoarding and falsework should be used to enhance
the possibility of recycling. The purchasing of construction materials will
be carefully planned in order to avoid over ordering and wastage. ¡P
The Contractor should recycle as much of
the C&D materials as possible on-site. Public fill and C&D waste
should be segregated and stored in different containers or skips to enhance
reuse or recycling of materials and their proper disposal. Where
practicable, concrete and masonry can be crushed and used as fill. Steel
reinforcement bar can be used by scrap steel mills. Different areas of the
sites should be considered for such segregation and storage. |

General
Refuse ¡P
The site and surroundings shall be kept
tidy and litter free. General refuse generated on-site should be stored in
enclosed bins or compaction units separately from construction and chemical
wastes. ¡P
A reputable waste collector should be
employed by the Contractor to remove general refuse from the site, separately
from construction and chemical wastes, on a daily basis to minimize odour, pest and litter impacts. Burning of refuse on
construction sites is prohibited by law. ¡P
Aluminium
cans are often recovered from the waste stream by individual collectors if
they are segregated and made easily accessible. Separate labelled
bins for their deposit should be provided if feasible. ¡P
Office wastes can be reduced through the
recycling of paper if volumes are large enough to warrant collection.
Participation in a local collection scheme should be considered by the
Contractor. In addition, waste separation facilities for paper, aluminum
cans, plastic bottles etc., should be provided. ¡P
Training should be provided to workers
about the concepts of site cleanliness and appropriate waste management
procedure, including reduction, reuse and recycling of wastes. ¡P
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. ¡P
All waste containers shall be in a secure
area on hardstanding. |
