1.3.1
This WMP
will describe the arrangements for avoidance, minimization, handling, reuse,
recovery and recycling, storage, transportation, collection, treatment and
disposal of the different categories of waste that are expected to be generated
during the construction activities of the Contract. This WMP includes the recommended
mitigation measures on waste management that are contained in the EIA report
and EM&A manual.
1.3.2
The main
objectives of this WMP are to:
l Provide
reference to the applicable environmental legislation and guidelines pertaining
to waste management.
l Clarify
each party¡¦s responsibilities regarding waste management, and identify the
personnel from each party that are assigned these responsibilities and their respective
role on the Contract.
l Establish
waste management practices and treatment procedures, for the avoidance,
minimization, material reuse/recovery/recycling, collection, transportation,
storage and disposal of wastes that are generated during the course of the Contract
that are specified by the EP and the implementation of the mitigation measures
that are outlined in the EIA report.
1.4.1 An Environmental Policy has been established by
Leighton ¡V Chun Wo Joint Venture to
outline guidance, technical information, and instructions to designated
personnel who will be responsible for the management of site environmental
issues, and to ensure that all statutory and contractual environmental
requirements and the Company Environmental Policy are followed. In
addition, Leighton ¡V Chun Wo Joint Venture will create an Environmental Management Team (EMT) for establishing and
implementing effective and efficient environmental protection procedures for
the Contractor.
1.4.2 The Environmental Policy Statement, together with the Environmental
Objectives and Targets, are listed below in
the Leighton ¡V Chun Wo Joint Venture Environmental Policy:
¡P
Comply with all applicable environmental
laws, regulations and contractual obligations;
¡P
Taking all practicable steps to prevent
adverse environmental events and provide rapid and appropriate response to
address any events that occur;
¡P
Managing resource usage to protect the
environment and improve our business performance
¡P
Creating project opportunities that utilize
new environmental technologies;
¡P
Maintaining an effective environmental
management system that is aligned and implemented to international standard
(ISO14001) to manage performance on project, set and review targets, allocate
resources and continually improve our environmental performance;
¡P
Provide appropriate training for our
employees, subcontractors and others working on our behalf to improve awareness
and knowledge of our system and their roles and obligations
1.5.1 Leighton ¡V Chun Wo Joint Venture aims to recover, avoid and
minimize the construction waste generated
on site by utilizing the hierarchy illustrated below. This 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. Through good planning, and effective
site management practices, Leighton ¡V Chun Wo Joint Venture will minimise the
amount of construction waste that is generated. The objective of Leighton ¡V Chun Wo
Joint Venture is to reduce and minimize the amount of wastes generated and hence minimise the costs associated
with subsequent waste handling and disposal.
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.
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).

Site Specific Waste Management
3.1.1 The key to successful waste management is undertaking
proactive measures to reduce the amount of waste generated. Waste management options/programme will
be exercised in accordance with the
hierarchy outlined in Table 1 below:
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.
3.2.1 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.
3.3.1 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.

4.1.1
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 Engineer¡¦s 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.
4.2.1 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:
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.
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) week¡¦s 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.
4.3.1 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 CEDD¡¦s or the EPD¡¦s 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.
4.4.2 Wastes collected on all the
wheels and bodies of trucks will be washed off by wheel washing facilities before leaving
the construction site. Leighton ¡V Chun Wo Joint Venture will provide wheel washing facilities on site at
the site entrance.
4.5.1
Where Leighton
¡V Chun Wo Joint Venture has identified a project that can serve as an
alternative disposal facility, Leighton ¡V Chun Wo Joint Venture will provide a
detailed description of the alternative disposal ground, including location, lot
number (where appropriate) and location plan(s) to the ER to request for his written approval to dispose of waste at the
proposed location.
4.5.2
Where the
alternative disposal facility is a private construction project, Leighton ¡V
Chun Wo Joint Venture will submit a letter from the Authorized Person of the
development (as defined under the Building
Ordinance) to confirm that:
l The use
of C&D materials in the development is acceptable.
l The
use of land formed by C&D materials is in conformity with the statutory
town plan / lease conditions.
l The ER
is allowed to enter the alternative facility to conduct an inspection when
necessary.

measures will be implemented:
¡P
Temporary stockpiling
site of untreated marine mud will be lined with impermeable sheeting, bunded and with
proper leachate control measures implemented;
¡P
Watering for the temporary
stockpiles of untreated marine mud will be avoided to minimise potential contaminated runoff ;
¡P
Temporary stockpiles
will be covered properly by impermeable sheeting;
¡P
Vehicles containing
any untreated marine mud will be suitable covered to limit potential dust
emission or potential contaminated wastewater run-off;
¡P
The mixing of marine
mud with cement will be enclosed to minimize dust emission;
¡P
Handling an mixing of
cement will follow Air Pollution Control (Construction Dust) Regulation to avoid
fugitive dust emissions;
¡P
Impermeable materials
(e.g. concrete paved ground) will be placed at the bottom of mixing unit/curing area for
the duration of the Cement S/S treatment process;
¡P
Concrete bund will be
constructed as appropriate, along the perimeter of the Cement S/S treatment
facilities to prevent leachate from escaping out of facilities.
4.9.3 The layout of the excavated sediment treatment area is
shown in Appendix H.
