Environmental Mitigation Implementation Schedule for Waste
Management
Environmental
protection and sustainable development are part and parcel of the daily
operations of the Gammon Construction Limited (referred to hereinafter as the
GCL). GCL will initiate appropriate
actions in order to minimize, and where possible eliminate, the environmental
impact arising from the construction of this project.
Gammon
Construction Limited (GCL) has been awarded of the Contract No. HY/2012/07 –
Tuen Mun Chek Lap Kok Link – Southern
Connection Viaduct Section for Highways Department (HyD) of the Government of the Hong Kong Special
Administrative Region (HKSARG). The
Works to be executed comprise the design and construction of a dual 2-lane
elevated carriageway between the HZMB HKBCF and North Lantau Highway (NLH) with associated slip roads, as well as
modifications and realignment of sections of the NLH and
The Waste
Management Plan (WMP) has been prepared to describe the arrangements for
minimising the generation of construction and demolition (C&D) materials and
disposing of the surplus C&D materials during the course of the Works.
This
contract-specific WMP shall be deposited to the Director of Environmental
Protection in accordance with the Condition 2.10 of the
Environmental Permit No. EP-354/2009/A..
The WMP shall address the potential and actual
impacts and necessary mitigation measures in light of the preferred construction
programme and consists of the following:-
·
A review
of the ordinances, regulations, codes of practices as well as contractual
obligations that are applicable to the wastes arising from the
Works;
·
An
organisation chart setting out the roles and responsibilities of the GCL’s
personnel responsible for waste management and appropriate mitigation
measures;
·
An
analysis of timing, quantities and types of C&D materials are anticipated to
be generated in the course of the execution of the Works;
·
A
classification of C&D materials into inert portion (Public Fill) and
non-inert portion (C&D Waste);
·
Proposals for avoiding/minimizing, handling, recycling, reuse,
return, storage and disposal of C&D materials, chemical waste and general
refuse;
·
An
appraisal of the potential establishment on site of a sorting facility,
including the identification of potential area on-site of facilitate the waste
sorting;
·
A
proposal for maintaining the site in a clean and tidy
condition;

The various waste management options shall be categorised in terms of
preference from an environmental viewpoint. The options considered to be more
preferable have the least impacts and are more sustainable in the longer
term. Hence, the hierarchy of waste
management is as follows:
·
Avoidance and
minimisation, i.e. not generating waste through changing or improving practices
and design;
·
Reuse of
materials, thus avoiding disposal;
·
Recovery and
recycling, thus avoiding disposal; and
·
Treatment and
disposal, according to relevant laws, guidelines and good
practice.
This hierarchy shall be used to evaluate waste management options, thus allowing maximum
waste reduction. Waste reduction
measures shall be introduced at the detailed planning stage and carried through
the construction activities, whenever possible, by careful purchasing control,
reuse of formworks and good site management. By reducing or eliminating over-ordering
of construction materials, waste is avoided and costs are reduced both in terms
of purchasing of raw materials and in disposing of
wastes.

The waste generated from the construction activities shall be divided
into distinct categories based on their composition, as follows:
(a) Construction and demolition (C&D)
materials
(i)
Inert C&D materials
(ii)
Non-inert C&D materials
(b) Chemical wastes
(c) General refuses
(d) Dredged marine sediments
(i) Uncontaminated marine sediments (Cat. L
)
(ii)
Contaminated marine sediments (Cat. Mp
& Mf)
A
quantities of
excavated materials to be generated, reuse on- or offsite during works has been
estimated and shown in Appendix D.
The estimated quantities, types of the C&D materials and corresponding
disposal grounds will be updated monthly and indicated in the monthly programme for disposal of C&D materials, which will be
reported to the SOR via submissions of monthly waste flow tables as shown in Appendix
E. All
anticipated disposal scenarios and transportation modes are summarized in Appendix
F.
C&D materials comprise unwanted
materials generated during construction, including rejected structures and
materials, materials which have been over ordered or are surplus to
requirements, and materials used and discarded.
C&D material could be divided into two
categories according to whether they are inert or non-inert. Inert C&D
material are known as rock, rubble, boulder, earth, soil, sand, concrete,
asphalt, brick, tile, masonry and used bentonite,
where to be maximized the reuse of these materials within the Contract and to be
disposed of the surplus of these materials to other Contracts, subjected to the
approval or direction of Supervising Office Representative (SOR). Under any
circumstances that no site is able to receive the unsuitable C&D materials
for the filling purpose, GCL will apply to CEDD for the public fill reception
facilities (PFRF) as a back-up option.
Non-inert C&D material
are such as metal, timber, vegetation, packaging waste, organic material and all
recyclables and non-recyclables is called “C&D Waste”. C&D waste,
excluding recyclables, shall be disposed of at NENT
Landfill.
Recyclables are mainly metals, paper/cardboard packaging and
plastics. Plastics refer to plastic bottles/containers, plastic sheets/foam from
packaging material. Recyclables would be collected by
relevant recyclers. Non-recyclable materials are treated as general
refuse.
The following general low waste construction
designs and principles together with careful planning shall be adopted to
avoid/minimise C&D material generation. Such measures include:
-
(a)
Management of construction materials such that over-ordering, poor
storage and maintenance, mishandling as well as improper operation procedures
shall be avoided.
(b)
Restriction on use of hardwood such that softwood, metal props and/or
proprietary steel system shall be considered for false work and the shoring of
trenches and pits;
(c)
The
formwork shall be designed to maximise the use of standard wooden panels so that
high reuse levels can be achieved.
More durable alternatives such as steel formwork or plastic facing shall
be considered for repetitive areas to increase the potential for reuse.
(d)
C&D materials shall be, as much as possible and practicable,
separated into reusable items and materials to be disposed of or recycled. It
shall be conducted at the immediate working area to avoid loss/leakage and cross
contamination during handling.
(e)
All
C&D materials arising from or in connection with the construction and
demolition work shall be sorted on-site and be separated into different
categories for disposal at landfills, public filling areas, or reuse and
recycling as appropriate. The
sorting area may be revised from time to time in order to suit the construction
activities.
(f)
Useful materials such as timber, rubble and steel/metal shall be
segregated for reuse. For example formwork and timber shall be cleaned for
reuse, off-cuts of reinforcement shall be sorted into usable lengths and short
off cuts stacked for scrap metal.
Where it is no longer reusable, scrap steel and metal items will be
collected by recycling companies.
(g)
Segregated materials shall be temporarily stored at designated areas
for reuse on site. Steel will be stored at the reinforcement yards, timber at
the formwork yard and rubble in a stockpile (either covered or sprayed to
control dust). Cardboard and paper
packaging recovered from site shall be properly stockpiled in dry condition and
covered.
(h)
In order to avoid over-order of concrete, accurate calculation shall
be made prior to concrete pouring.
Close supervision shall also be arranged during concrete pouring to avoid
over-cast.
(i)
Surplus concrete shall be used for paving of temporary road or cast
of concrete blocks for bunding etc. as far as
practicable. In case immediate use
of surplus concrete cannot be identified, the surplus concrete will be
temporarily poured into designated surplus concrete pouring areas on site for
further disposal to public filling areas.
(j)
Entirely cover every stock of more than 20 bags of cement by
impervious sheeting and carry out the de-bagging, batching and mixing processes
in an area sheltered on the top and the 3 sides.
Damp and gather the waste cement bags for proper
disposal.
(k)
Used
bentonite shall only be disposed of at Public Fill
area.
GCL designate suitable
areas onsite for the storage, sorting and segregation of construction
waste. The areas that are
designated by GCL will be clearly defined with appropriate signage and barriers
(or similar) and allow for easy access by workers and vehicles. As the project progresses it is
anticipated that the designated areas will be reviewed depending upon
construction program requirements.
The areas designated by GCL will be sufficient for the amounts of
construction waste that are anticipated to be generated during the course of the
contract. The sorting mechanism is shown in Table 8.1. The tentative locations for the
temporary storage and sorting of C&D waste are shown in Appendix G.

Marine
sediment means excavated from the Works of the foundation and associated
substructures at the sea. It could be classified as
contaminated and uncontaminated based on its contamination level with reference
to Chemical Exceedance Level (CEL) laid down in the
Appendix A of the ETWB TCW No. 34/2002. The excavation and disposal of marine sediments
generated shall be minimized from the Works in this
Contract,
e.g. only from the excavation of the foundation and the associated substructures
such as the piles, pile caps and piers. In events that dredging/ excavation of
marine sediment are unavoidable, the GCL shall handle/ process such marine
sediment in accordance with the procedures given in ETWB TCW No. 34/2002. GCL
will apply to the EPD for all valid permits and licenses in accordance with only
dispose of the marine sediment at the designated disposal facilities as directed
by the Director of Environmental Protection and/or the Marine Fill Committee
(MFC) unless otherwise agreed or ordered in writing by the Supervising Officer.
The copy of memo from Marine Fill Committee of CEDD granting the allocations for
the sediment disposal space is attached in Appendix
H.
In case of disposal of any amount of the marine sediment in Hong Kong
waters, the dumping of sediments shall be strictly within the designated
sediment disposal sites and shall be controlled through a dumping permit issued
under the Dumping at Sea Ordinance (Cap 466), or called a DASO permit, by the
Director of Environmental Protection. Dumping shall take place at sub-areas
within the sediment disposal sites, the locations of which will be changed from
time to time as notified by the Director of Environmental Protection through the
Supervising Officer.
Subject to the instruction of SO, notwithstanding whether the GCL
elects to dispose of any or all dredged/excavated marine sediments at the
designated sediment disposal sites in Hong Kong, the GCL will apply for approval
to relevant authorities in Mainland and Hong Kong for the cross-boundary
disposal of Cat. L and Mp
sediments at the tentative disposal site of South Dangan Liedao (擔杆列島). This cross-boundary disposal option shall only
proceed with the Supervising Officer’s instruction. In the event that the
approval of cross-boundary disposal is not obtained in a timely manner, Cat. L and Mp sediments
would be arranged to dispose of at South Cheung Chau Open Sea Sediment Disposal
Area and East Sha Chau or South of the Brothers Marine Sediment Disposal
Facility as a fallback option to be authorized by
Supervising Officer, EPD and CEDD-MFC.
In
cases that off-site disposal of marine sediment in Hong Kong Water required, GCL
shall apply for the allocation of a sediment disposal site in the name of
Highways Department of the HKSAR, and marine loading permits under Dumping at
Sea Ordinance (Cap. 466) (DASO) for the disposal of marine sediment at the
designated disposal facilities in Hong Kong.
The marine sediment of Category M failing
biological tests as defined in ETWB TC(W) No. 34/2002 shall be disposed of
in
CEDD-MFC's designated contaminated mud pits in Hong Kong waters, at mud pit of
East Sha Chau or South of the Brothers Marine Sediment Disposal Facility as
allocated
by CEDD-MFC. GCL shall place the contaminated mud at a location and in a manner
as directed on site by the CEDD management team. GCL shall proceed with the
disposal operation as instructed by the management team and in accordance with
the relevant sections of the Requirements of the Contaminated Mud Pit Management
Scheme which may be modified from time to time by the management team. GCL shall
not carry out any dumping without permission of the management team or when the
management team is not in operation. GCL will carry out the dumping operation in
strict accordance with the method statement agreed by the Licensing
Authority.
In accordance with DEVB TC(W) No. 6/2010,
with tender invitation was on or after 1 November 2010, the administration of
CHIT/ DDF was streamlined. CHIT in lieu of the bar-coded Disposal Delivery Form (DDF) should be used at
all prescribed facilities, i.e. public fill reception facilities,
sorting facilities, outlying island transfer facilities and landfills. Moreover,
under the Construction Waste Disposal Charging Scheme, GCL registered with EPD a
disposal account and will adopt the CHIT as the enhanced control of C&D
material disposal. The control procedure on off-site disposal of C&D
materials is shown in Appendix I. The sample of CHIT is given in Appendix
J.
Every C&D material disposal trip to the public fill reception
facilities and designated landfill shall be controlled under the trip-ticket
system as per the DEVB TC(W) No. 6/2010 in order to
avoid fly-tipping. Appendix G gives the site procedure for the TTS operation.
For disposal of chemical wastes, the trip-ticket system as per the
Waste Disposal (Chemical Waste) Regulation in which licensed collector will be
employed and the chemical wastes be disposed of at
designated chemical waste treatment facility.
GCL will inform all truck drivers engaged for removal
of C&D materials from the Site of the
following particular points:
·
Each truck carrying C&D
materials leaving the Site for a disposal ground must bear a duly completed
CHIT, irrespective of the location and nature of the disposal ground;
and
·
The C&D materials must be
disposed of at the disposal grounds stipulated in the Contract or directed by
the SOR or alternative disposal grounds approved by the
SOR.
GCL
would formulate a guiding protocol for truck
drivers being engaged and give all of them a copy for their information. Where
necessary, a tool box talk relating to the protocol will be given to all engaged
driver. The protocol is shown in Appendix
J.
GCL
shall arrange weekly inspection attended by the Environmental Officer and SOR to
inspect the site to ensure satisfactory performance on compliance with the WMP
with due regards to the followings:

GCL may
arrange the
weekly inspection on waste management performance to be carried out along with
the weekly safety walks for safety or other site
inspections.
GCL shall prepare and agree with the SOR a comprehensive checklist for use during weekly inspections on waste
management. The defects or deficiencies identified during the weekly inspection
on waste management together with their respective locations and the
corresponding due dates for rectification as set by the
SOR nominated site representative should be entered in a summary table
of follow-up actions similar to the one established for weekly safety walks for
monitoring of the rectification progress. GCL may need to prepare more than one
comprehensive checklist to suit the variety of works at various portions of the
Site. It is recommended that items
covered in the checklist should primarily
address:-
(a)
the physical conditions of the Site (e.g. housekeeping, site tidiness
and cleanliness, etc.);
(b)
the adequacy of measures applied to each category of waste;
and
(c)
the availability/accessibility/maintenance of waste management
facilities.
Immediately after the weekly inspection, the
summary table of follow-up actions shall be agreed and signed by both the
assigned person and the SOR and a copy should be kept by the
SOR for monitoring of the progress of rectification and for payment. GCL
shall take prompt action to rectify the deficiencies identified and shall report
the status of action taken before the forthcoming weekly inspection.
Should deficiency
with regard to
waste management affairs persists,
the Event Contingency Plan as detailed below shall be triggered. Non-compliance shall include the
following situations:
·
Infringement of legal requirements with respect to waste issues.
·
Persistent outstanding of control measures stated in the WMP as
identified during the site inspection or
audit.
·
Overloading of dump truck

also be provided, using the yearly summary WFT as given in Appendix
D. The yearly summary WFT covering the whole construction period
shall be included in the WMP and updated on yearly basis, 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.
To ensure the effectiveness
of the Trip-Ticket System, the following item will be discussed at every Site
Safety and Environmental Management Committee meeting, and Site Safety and
Environmental Committee meeting or ad-hoc meetings on as-needed
basis:
1. Review the site management plan
and implementation of the TTS, and identify areas for
improvement;
2. Audit the quantity of C&D
materials removed from the Site (based on the DRS and survey records) against
the quantities of C&D materials delivered to the disposal ground designated
in the Contract (e.g. based on EPD website) and directed or approved by the
Supervising Officer;

first 2 days of the employment and refreshment training shall be carried out by
every 6 months.
The Environmental Officer is allowed to develop and provide toolbox
talks for the topic on on-site sorting of C&D materials to promote the workers
The Section 12.6 of the EIA Report gives recommendations on
mitigation measures of waste management. The recommendations were extracted to
form an implementation schedule particularly for waste management during
construction phase and the schedule is shown in Appendix
M.
The Section 8.1.2 of the EM&A Manual gives recommendations on
mitigation measures of waste management, which
are:
·
The waste management hierarchy below should be strictly followed.
This hierarchy should be adopted to evaluate the waste management options in
order to maximise the extent of waste reduction and cost reduction. The records
of quantities of waste generated, recycled and disposed (locations) should be
properly documented.
·
A trip-ticket system should be established in accordance with
DEVB TC(W) No.
6/2010 and Waste Disposal (Charges for Disposal of Construction Waste)
Regulation to monitor the disposal of public fill and solid wastes at public
filling facilities and landfills, and to control fly-tipping. A trip-ticket
system would be included as one of the contractual requirements for the
Contractor to strictly implement. The Engineer would also regularly audit the
effectiveness of the system.
·
A recording system for the amount of waste generated, recycled and
disposed (locations) should be established. The future Contractor should also
provide proper training to workers regarding the appropriate concepts of site
cleanliness and waste management procedures, e.g. waste reduction, reuse and
recycling all the time.
·
The CEDD should be timely notified of the estimated spoil volumes to
be generated and the Public Fill Committee should be notified and agreement sort
on the disposal of surplus inert C&D materials e.g. good quality rock during
detailed design of the TM-CLKL project. Wherever practicable, C&D materials
should be segregated from other wastes to avoid contamination and to ensure
acceptability at public filling areas or reclamation
sites.
·
The extent of cutting operation should be optimised where possible.
Earth retaining structures and bored pile walls should be proposed to minimise
the extent of cutting.
·
Inert C&D materials from slopes and road pavement will be reused
for construction of the raised platform for the toll
plaza.
·
C&D materials generated by construction of cut slopes along NLH
at
·
The surplus surcharge should be transferred to a fill
bank.
·
Rock armour from the existing seawall should be reused on the new
sloping seawall as far as possible.
·
The site and surroundings shall be kept tidy and litter
free.
·
No waste shall be burnt on site.
·
Make provisions in contract documents to allow and promote the use of
recycled aggregates where appropriate.
·
Prohibit the Contractor to dispose of C&D materials at any
sensitive locations e.g. natural habitat, etc. The Contractor should propose the
final disposal sites in the EMP and WMP for approval before
implementation.
·
Stockpiled material shall be covered by tarpaulin and /or watered as
appropriate to prevent windblown dust and surface run
off.
·
Excavated material in trucks shall be covered by tarpaulins to reduce
the potential for spillage and dust
generation.
·
Wheel washing facilities shall be used by all trucks leaving the site
to prevent transfer of mud onto public
roads.
·
Dredged marine mud shall be disposed of in a gazetted marine disposal
ground under the requirements of the Dumping at Seas
Ordinance.
·
Standard formwork or pre-fabrication should be used as far as
practicable so as to minimise the C&D materials arising. The use of more
durable formwork or plastic facing for construction works should also be
considered. The use of wooden hoardings should be avoided and metal hoarding
should be used to facilitate recycling. Purchasing of construction materials
should be carefully planned in order to avoid over-ordering and
wastage.
·
The Contractor should recycle as many C&D materials (this is a
waste section) as possible on-site. The public fill and C&D waste should be
segregated and stored in separate containers or skips to facilitate the reuse or
recycling of materials and proper disposal. Where practicable, the concrete and
masonry should be crushed and used as fill materials. Steel reinforcement bar
should be collected for use by scrap steel mills. Different areas of the sites
should be considered for segregation and storage
activities.
·
All falsework will be steel instead of
wood, as far as possible.
·
Chemical waste producers should register with the EPD. Chemical waste
should be handled in accordance with the Code of Practice on the Packaging,
Handling and Storage of Chemical Wastes as
follows:
-
Suitable for the substance to be held, resistant to corrosion,
maintained in good conditions and securely
closed;
-
Having a capacity of <450L unless the specifications have been
approved by the EPD; and
-
Displaying a label in English and Chinese according to the
instructions prescribed in Schedule 2 of the
Regulations.
-
Clearly labelled and used solely for the storage of chemical
wastes;
-
Enclosed with at least 3 sides;
-
Impermeable floor and bund with capacity to accommodate 110% of the
volume of the largest container or 20% by volume of the chemical waste stored in
the area, whichever is greatest;
-
Adequate ventilation;
-
Sufficiently covered to prevent rainfall entering (water collected
within the bund must be tested and disposed of as chemical waste, if necessary);
and
-
Incompatible materials are adequately
separated.
·
Waste oils, chemicals or solvents shall not be disposed of to
drain;
·
Adequate numbers of portable toilets should be provided for on-site
workers. Portable toilets should be maintained in reasonable states, which will
not deter the workers from utilising them. Night soil should be regularly
collected by licensed collectors.
·
General refuse arising on-site should be stored in enclosed bins or
compaction units separately from C&D and chemical wastes. 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. Burning of refuse on construction sites is
prohibited.
·
All waste containers shall be in a secure area on hard standing;
Aluminium cans are usually collected and recovered from the waste stream by
individual collectors if they are segregated and easily accessible. Separately
labelled bins for their deposition should be provided as far as
practicable.
·
Office wastes can be reduced by recycling of paper if such volume is
sufficiently large to warrant collection. Participation in a local collection
scheme by the Contractor should be advocated. Waste separation facilities for
paper, aluminium cans, plastic bottles, etc. should be provided
on-site.
·
Training shall be provided to workers about the concepts of site
cleanliness and appropriate waste management procedure, including waste
reduction, reuse and recycling.
