Procedure on off-site disposal of C&D materials
This Waste Management Plan (WMP) sets out in
detail the approaches CRBC ¡V KADEN JV should adopt in the management of waste
generated from the various different construction activities. It also sets out the
procedures for the waste management activities and requirements during the
construction.
To demonstrate the
Project Team¡¦s commitment on the continual improvement of our waste management
performance, the project waste management policy has been established as below:
The following
legislation relates to the handling, treatment and disposal of wastes in Hong
Kong, and should be observed with regard to all wastes generated and requiring
disposal due to the construction, where applicable:
¡P
Waste Disposal Ordinance (Cap 354)
¡P
Waste Disposal (Chemical Waste)
(General) Regulation (Cap 354)
¡P
Waste Disposal (Charges for Disposal of
Construction Waste) Regulation (Cap 354)
¡P
Land (Miscellaneous Provisions)
Ordinance (Cap 28)
¡P
Public health and Municipal Services
Ordinance (Cap 132) ¡V Public Cleansing and Prevention of Nuisances (Urban
Council) and (Regional Council) By-Laws
The Waste Disposal
Ordinance (WDO) prohibits the unauthorized disposal of wastes. The illegal tipping or flytipping
of wastes on unauthorized sites is also controlled under the WDO. Under the
Waste Disposal (Construction Waste Disposal Charging Scheme) Regulation,
project team should apply for a billing account from EPD for disposal of
construction wastes generated from the project. The regulation prescribes the
requirements of handling of construction wastes on site and the construction
waste disposal-charging scheme.
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 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.
Construction wastes that are wholly inert would be taken to public
dumps. Public dumps usually form part of land reclamation schemes operated by
the Civil Engineering and Development Department (CEDD). The Land
(Miscellaneous Provisions) Ordinance requires that individuals or companies who
deliver suitable construction wastes to public dumps obtain dumping licenses.
CEDD issues the licenses under delegated powers from the Director of Lands.
The Public Cleansing and Prevention of Nuisances By-Laws provide
further controls on the illegal tipping of wastes on unauthorized (unlicensed)
sites.
The project team should obtain all necessary permits and licenses under
these ordinances including, but not limited to:
¡P
Chemical waste permits/ licenses under
the Waste Disposal Ordinance (Cap 354)
¡P
Billing Account for construction waste
disposal-charging scheme (Cap 354)
The following
guidelines related to waste management and disposal would be adhered to during construction
of the project:

In order to make use of
C&D materials generated by the Site, JV will identify and use recycling
facilities or other construction sites where such materials can be used before
obtaining the written approval of the Engineer. Relevant information should be
submitted to the Engineer as following:
(a)
A detailed
description of the alternative disposal ground, including location, lot number
(where appropriate), location plan and photographs of the proposed alternative
disposal grounds showing the surrounding environment and land use;
(b)
where the
alternative disposal ground is a private construction site, a letter from each
of the relevant authorities, such as Agriculture, Fisheries and Conservation
Department, Lands Department and Planning Department, to comment on suitability
of the site under their respective purview, and a letter from the Authorized
Person of the development to confirm:-
1)
The C&D
materials for use in the development is acceptable;
2)
The
land/pond filling in the proposed alternative disposal ground and the use of
land so formed by the C&D materials are in conformity with the statutory
town plan/lease condition; and
3)
The
Engineer¡¦s staffs are allowed to enter the alternative ground to conduct
inspections where necessary.
(c)
where the
alternative disposal is a private recycling facility, it is on the recyclers¡¦
list for C&D materials recognized by EPD, as well as a letter from the
operator to confirm the Engineer¡¦s staff are allowed to enter the recycling
facility to conduct inspections where necessary;
(d)
where the
alternative disposal ground is a construction site of Government (other than a
government contract quarry), Hong Kong Housing Authority or Mass Transit
Railway Corporation, a written consent from the project office of the alternative
disposal ground to use the C&D materials generated from the Site;
(e)
where the
alternative disposal ground is a government contract quarry, a written consent
from the Mines Division of Civil Engineering and Development Department to
import the C&D materials generated from the Site;
(f)
the
estimated quantity and type of C&D materials to be used/processed in the
alternative disposal ground and the approximate delivery programme,
together with the name, post and specimen signature of the competent person to
sign the Disposal Delivery Form (DDF); and
(g)
a system for transmitting disposal records
from the alternative disposal ground to the Engineer¡¦s Representative.
The purpose of this section is to describe the proposed mitigation
measures considered to ensure that all wastes generated during the construction
and demolition are well-managed on-site, transported and disposed of in a
manner that is both environmentally acceptable and in full compliance with
statutory and contractual requirements. A Site Layout Plan indicated the area
for the waste management such as temporary storage area, waste sorting area and
disposal area as presented in Appendix B.
¡± Design and programme excavation works so that
the materials excavated can be re-used as back-fill material to balance cut and
fill and hence reduce the generation of excavated materials.
¡± Right amount of raw materials should be ordered at the right time with
proper control and documentation on material flow to minimize over-ordering.
Raw materials should be fully utilized to avoid wastage
¡± Surplus materials should be returned to stock in centralized area with
suitable protective measures. If possible, surplus materials should be exchange
with other sites, to minimize material wastage
¡± Careful design and planning and good site management should be
maintained to minimize over ordering and generation of waste materials such as
concrete, mortars and cement grouts
¡± Sequence of
demolition should be planned to allow the separation and sorting of building
materials.
¡± Avoid, reduce or minimize the use of timber in temporary works
construction as far
¡± as possible. Procedures of using timber should be established guiding the
use of timber on site, in order to reduce or minimize the use of timber. The
design of formwork should maximize the use of standard wooden panels so that
high level of reuse can be achieved
¡± Steel false work should be used as much as possible to reduce the
amount of waste timber generated from the project
¡± Current operation procedures including any waste reduction measures
should be reviewed, especially during installation and cutting, to avoid
unnecessary use
¡± Broken items or offcuts should be used when sections of small lengths
are required
¡± If cut and fill could not be balanced on-site, suitable excavated
materials should be sorted on site to recover the inert portions (e.g. soil and
broken rock) for reuse on site before the remaining materials are disposed off site or disposal to designated Public Filling Facility
¡± Carefully plan/program excavation and backfilling activities so that
excavated materials can be used for backfilling within the site
¡± Excavated material should be reused as close to the point of excavation
and as soon after excavation as possible and directly transferred to the area
of deposition, if practicable.
¡± The inert C&D materials generated from the toll plaza cut slopes will be used for construction of the raised platform for the toll plaza where
possible.
¡± All C&D materials arising from or in connection with demolition
work should be sorted on-site and be separated into different groups for
disposal at landfills, public filling facilities or recycling appropriate
¡± Identify and list out all work processes or activities that should
generate reusable/ recyclable materials during construction and demolition
¡± For those suitable inert C&D materials (e.g. broken concrete from
demolition or road improvement works) should be properly sorted for recycling
into aggregates and recover the materials for on -site usage
¡± 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
¡± Procedures of the handling of reusable/ recyclable materials should be
established
¡± Recycle suitable C&D materials by transporting the materials to
designated C&D materials recycling facilities for processing
¡± All materials should be reused on site as far as practicable, including
formwork plywood, hoardings, scaffolding, trench supports, topsoil and
excavated materials.
¡± Where necessary, alternatives such as metal scaffolding, steel formwork
or plastic facing should be considered to increase the potential for reuse.
¡± Suitable materials, such as 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
¡± Reputable recycling contractors with valid licenses and fulfilling all
the legislative requirements should be employed to facilitate that recyclable
materials sorted from the site are collected with reasonable care
¡± The quantities of all the recyclable materials should be recorded
before removal off site
The materials stockpiled on-site should
be managed in order to prevent any potential impacts. Following measures should
be considered in order to properly manage the stockpiled materials:
¡± Identify and
provide sufficient space for temporary storage of C&D materials to
facilitate collection and/ or sorting on site
¡± Stockpiled
materials should be sited away from any stream courses so as to avoid releasing
materials into the water bodies
¡± Demolished debris
should not be accumulated on the floors unless the debris accumulation is
justified by engineering calculations
¡± No stockpile of
construction materials, debris, formworks, or other forms of obstructions is
allowed to block the accesses throughout the entire construction period
¡± Location to
minimize visual impacts and nuisance related to noise and air quality (dust) to
any sensitive receivers
¡± Storage of
material on site should be kept to a minimum to avoid nuisance to local
residents
¡± Keeping the movement
of stockpiled material to a minimum
¡±
¡± Stockpiled
materials should be covered by tarpaulins and/or watered as appropriate to
prevent windblown dust and/or surface run-off.
¡± Measures such as
providing sand bag barriers should be provided to prevent the washing away of
construction materials, soil, silt or debris into any drainage system. Any
washout of construction or excavated materials should be diverted to the
drainage system via sediment traps
¡± All surplus
excavated material generated from the project should be disposed of at the
designated Public Filling Facility
¡± According to the
Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap.
354N), Construction Waste Disposal Charging Scheme mentioned in Section 5.10 in
this WMP should be implemented during the construction.
¡± The acceptance
criteria for Public Filling Facility and Landfill should be followed
¡± All inert C&D
materials generated from this contract should be disposed of at the designated Public
Filling Facility. Such materials should be free from marine mud, household
refuse, plastic, metal, industrial and chemical waste, animal and vegetable
matter and other matter considered unsuitable by Filling Supervisor
¡± All dump trucks
used for delivery of public fill to public filling facilities should have valid
Dumping Licenses issued by CEDD. The inert C&D materials delivered to the
public filling facilities should be in accordance with the conditions in the
dumping license
¡± All non-inert
portions of C&D material (C&D waste) generated from the project should
be disposed of at the designated landfill and/ or other disposal outlet as
directed by the Engineer. Should provide EPD with one week¡¦s advance notice
before starting to deliver the C&D waste to the landfills and should inform
EPD of any subsequent changes to the disposal programme
during the contract period
¡± Trees and
vegetation should be stripped prior to site clearance, chopped and compacted
using suitable mobile compactors to reduce the volume of material to be
transported and disposed of
¡± Should not permit
any sewage, wastewater or effluent containing sand, cement, silt or any other
suspended or dissolved material to flow from the site onto any adjoining land
or allow any waste matter or refuse which is not part of the final product from
waste processing plants to be deposited anywhere within the site or onto any
adjoining land
¡± In order to
minimize the impacts of demolition works, the wastes should be cleared as
quickly as possible after demolition
¡± When any
components of a structure or water mains to be demolished and are suspected to
be consisting of asbestos, the project team should inform the ER. Any work which involves the use or handling of asbestos containing
materials must strictly follow the following procedure:
¡± employ a
registered asbestos consultant to conduct an asbestos investigation and prepare
an asbestos investigation report and an asbestos abatement plan;
¡±
¡± submit the
asbestos investigation report and the asbestos abatement plan to the
Environmental Protection Department at least 28 days before start work on the
asbestos containing materials;
¡±
¡± notify the
Environmental Protection Department of the date of commencement of work on
asbestos containing materials at least 28 days in advance;
¡±
¡± employ a
registered asbestos contractor to carry out the asbestos work in accordance
with the asbestos abatement plan;
¡±
¡± employ a
registered asbestos consultant to supervise the implementation of the asbestos abatement
plan and the work of the registered asbestos contractor; and

Site Management
Plan for Trip Ticket Implementation
A Site Management Plan (The Plan) will be prepared which includes the
implementation of TTS. The Plan should include site organization and staff
duties, disposal programme, site procedures for duly completed of CHIT/DDF, as
presented in Appendix E and Appendix F etc.
A comprehensive register of the disposal delivery for recording the
disposal of C&D materials and waste will be established. The register will
also cover the recyclable materials removed by the recycling contractors off
the Site. The quantity (ton) of the C&D material shall be recorded in the
register.
Record Keeping
For the management of CHIT/DDF, the following procedures and record keep
will be implemented to all dumping activities.
(a) For each truckload of C&D materials leaving
the Site, the truck driver must bear a duly completed CHIT/ DDF;
(b) A daily record of disposal, as presented in Appendix D, of C&D materials from
the Site including CHIT/ DDF numbers, vehicle registration marks, drivers¡¦
particulars, approximate volume, C&D materials type, designated disposal
ground, departure time from the Site, actual disposal ground and arrival time
at disposal ground should be maintained. Part 1of the DRS completed by JV in
duplicate and inform the Engineer¡¦s staff before departure of the vehicle. The
Engineer¡¦s staff shall sign Part 1 of the DRS before departure of the trucks,
or to suit site operations at other time to be agreed between the Engineer¡¦s
Representative and JV;
(c) The truck shall proceed to the disposal ground
as stipulated in the designated disposal ground. The truck driver shall present
the CHIT/ DDF to the operator of the disposal ground. For a prescribed
facility, if the C&D materials accord with the acceptance criteria, disposal
of the materials will be permitted and the facility operator will give the
driver a Transaction Record Slip and stamp the CHIT.
(d)
For
disposal ground other than prescribed facilities, the DDF should be signed off
by a competent person as agreed by the Engineer at the disposal ground to
confirm completion of each trip. A daily record with details of each disposal
trip from the Site to the disposal ground will be maintained. The completed
Part 2 of the DRS form should be submitted to the Engineer.
Chemical waste, as defined under the Waste
Disposal (Chemical Waste) (General) Regulation, includes any substance being
scrap material, or unwanted substances specified under Schedule 1 of the Regulation.
Substances likely to be generated by construction activities arise from the
maintenance of construction plant and equipment. These include, but not limited
to the following:
¡±
Scrap batteries or spent acid/alkali from their maintenance;
¡±
Used engine oils, hydraulic fluids and waste fuel;
¡±
Spent mineral oils/cleaning fluids from mechanical machinery; and
¡±
Spent solvents/solution, some of which may be halogenated, from
equipment cleaning activities.
It is anticipated that the quantity of chemical
waste, such as lubricating oil and solvent produced from plant maintenance,
should be small for this project.
Storage, handling, transport and disposal of chemical waste should be
arranged in accordance with the Code of Practice on the Packaging, Labeling and
Storage of Chemical Waste published by EPD.
General:
¡± No maintenance
activities which may generate chemical wastes should be undertaken directly on
the ground;
¡± Stored volume shall not be kept more than 450 litres
unless the specification has been approved by the EPD. Storage area should be
enclosed by three sides by a wall, partition of fence that is at least 2m
height or height of tallest container with adequate ventilation and space;
¡± Any unused chemicals or those with remaining functional capacity shall
be recycled;
Containers used for the storage of chemical wastes:
¡± Be suitable for the substance they are holding, resistant to corrosion,
maintained in a good condition, and securely closed
¡± Have a capacity of less than 450 litre unless
the specifications have been approved by EPD
¡± Display a label in English and Chinese in accordance with instructions
prescribed in Schedule 2 of the Regulation
Labeling:
¡±
Every container of chemical waste
should bear an appropriate label containing the particular details of the
chemical waste it contained. The waste producer 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
Storage area:
¡±
Be clearly labeled and used solely for
the storage of chemical waste
¡±
Be enclosed on at least 3 sides

After spill is
contained remove material (including contaminated soil where necessary) using
pumps and/or absorbent materials
¡±
Dispose of the materials, including the
contaminated soil as chemical waste
The presence of a construction site with large
numbers of workers and site offices should result in general refuse requiring
disposal. This should mainly consist of food waste, aluminium cans and waste
paper.
¡±
Temporary storage
areas should be identify and provided for the temporary storage of general
refuse to facilitate collection
¡±
General refuse
generated on-site should be stored in enclosed bins or compaction units
separate from construction and chemical wastes

Temporary storage
areas for general refuse should be enclosed to avoid environmental
impacts. Sufficient dustbins should
be provided for storage of waste as required under the Public Cleansing and
Prevention of Nuisances Ordinance (Regional Council) By-laws
¡±
General refuse
should be cleared daily and should be disposed of to the nearest licensed
landfill or refuse transfer station
¡±
Separate labelled
bins should be provided to segregate the waste generated by workforce. Waste
recycle collector should be employed to collect the segregated waste
¡±
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
¡±
Office waste should
be minimized through using papers on both sides. Communication by electronic
means should be used as far as possible
¡±
Open burning of
refuse on-site is prohibited by law and should not be undertaken
¡±
Toilet wastewater
should be transported by a licensed contractor to a Government Sewage Treatment
Works for disposal in accordance with the Sanitation and Conservancy (Regional
Council) By-laws

To control the rodent problem, the Site shall
be maintained in a tidy state at all times to discourage rodent harbourage and detect rodents at an early stage. Refuse and
food must be kept in containers with well-fitted covers/rodent proof store
rooms to deprive rodents of food. The Contractor shall not attempt to disinfect
rodents by themselves but shall appoint a pest control services contractor for
rodent control services or contact district pest control offices or the Pest
Control Advisory Section of the Food and Environmental Hygiene Department for
rodent control advice.
In order to enhance the awareness of the workers
including those of the sub-contractors¡¦ on waste management on site,
site-specific induction training and regular toolbox talks topic related but
not limited to site cleanliness and appropriate waste management procedures
including waste reduction, reuse and recycling should be provided to all site
staff.
Environmental Officer should identify the need
and arrange relative trainings for all employee and the sub-contractors¡¦
workers involved in the works.
The training should cover the waste management
policy, targets, measures for on-site sorting of C&D materials and
measurement on waste management performance on the site.
An auditable record should be maintained for all
environmental training undertaken.
Site environmental inspection should be conducted in a monthly basis.
The Environmental Officer or Site Administrator and the Engineer or his
delegate should attend the inspection, in order to evaluate the overall performance of the implementation of
the WMP and ensure the appropriate control measures are properly implemented. The inspection
should also cover waste sorting, storage and disposal.
The aims and objectives of waste management
inspection are:
¡± To ensure that the waste arising from works are handled, stored,
collected, transported and disposed of in an environmentally acceptable manner;
