The Frontier Closed Area (FCA) is an
integral part of the package of measures aimed at maintaining the integrity of
the boundary of the Hong Kong Special Administrative Region (HKSAR) with
mainland
The PBF and SBF (hereafter referred
to as ‘The Project’) will be erected along the northern and southern curbs of
the realigned BPR respectively to facilitate the Hong Kong Police Force (HKPF)
in combating cross-boundary criminal activities. The reduced FCA will comprise a narrow strip
of land covering the realigned BPR and areas to its north, together with the
points of crossing the boundary (i.e. the Boundary Control Points and Sha Tau
Kok town). Areas south of the SBF will
generally be excised from the FCA.
An Environmental Impact Assessment
(EIA) for the proposed works was carried out under the Environmental Impact
Assessment Ordinance (EIAO, Cap 499). An EIA Report and an Environmental
Monitoring and Audit (EM&A) Manual were completed in January 2009 and
approved by the Environmental Protection Department (EPD) in April 2009
(Register No. AEIAR-136/2009). The entire length of the proposed works is about
21.7 km from west of Pak Hok Chau to east of Sha Tau Kok and is divided into
four sections. A general layout plan of the Project site is presented in Figure
1.1, while the location of the SBF at Section 4 in
Sha Tau Kok is presented in Figure
1.2.
An Environmental Permit (EP)
covering the overall proposed works was issued in June 2009 (Permit No.
EP-347/2009). An application for Variation of the Environmental Permit (VEP)
(Application No. VEP-314/2010) was subsequently submitted on 24 May 2010 and
the amended Environmental Permit (Permit No. EP-347/2009/A) was issued by EPD
on 9 June 2010.
With regard to Section 4, an
application for a Further Environmental Permit (FEP) covering the works under Works
Order No. ASD 010962 (also known as Works Order No. 1) was submitted to EPD on
2 March 2010 (Application No. FEP-104/2010) and this was granted on 29 March
2010 (Permit No. FEP-03/347/2009). Furthermore, another application for an FEP
covering the works under Works Order Nos. ASD 010969 and ASD 010974 (also known
as Works Order Nos. 2 and 3 respectively) – including a new section of SBF
consisting of transparent panel, a new checkpoint and kiosk – was submitted to
EPD on 13 August 2010 (Application No. FEP-112/2010) and was granted on 7
September 2010 (Permit No. FEP-04/347/2009/A).
The Architectural Services
Department (ArchSD) has been entrusted with the management of the Project by
the Project Proponent – the Secretary for Security of the HKSAR Government.
Mott MacDonald Hong Kong Limited (MMHK) has in turn been commissioned by ArchSD
as the consulting engineer for the entire Project under Consultancy Agreement
No. 9SN005, and is the Engineer’s Representative (ER) for construction of the
Project.
For Section 4 of the Project, MMHK
and ENVIRON Hong Kong Limited (ENVIRON) have been commissioned as the
Environmental Team (ET) and Independent Environmental Checker (IEC)
respectively to undertake the Environmental Monitoring and Audit (EM&A)
programme as described in the approved EM&A Manual of the Project. Also,
the Contract to undertake and perform the construction works for Section 4 was
awarded to Chun Wo Construction & Engineering Company Limited (‘The
Contractor’) and is scheduled to last for approximately 18 months. It formally
commenced on 28 May 2010, and the construction works and EM&A programme
under the above-mentioned EP and FEP(s) also commenced on this date. The
construction works programme is presented in Appendix A.
This monthly EM&A report
summarises the environmental monitoring and audit works, list of activities and
mitigation measures implemented at Section 4 during the period of 1 to 31
December 2010 inclusive (‘reporting month’).
The scope of works for Section 4
consists of:
¡ Erection of an SBF from the entrance
of the Sha Tau Kok town (i.e. the location of ‘Gate One’) to the Sha Tau Kok
Control Point (approximately 0.5 km);
¡ Use of transparent panel for a
section of an SBF;
¡ Provision of a two-storey high
checkpoint at ‘Gate One’;
¡ Addition of a kiosk/guard house on

Summary of EM&A Requirements
The EM&A programme requires
environmental monitoring of construction noise as well as environmental site
inspections for air quality, noise, water quality, waste management, ecology,
landscape and visual, as specified in the approved EM&A Manual.
Originally, the EM&A Manual
designated two locations as noise monitoring stations during the construction
phase. However, currently noise levels at only one of these monitoring stations
(as shown in Figure
1.2) are monitored. The reasons for this arrangement
are detailed in Section 3.2.
A summary of impact EM&A
requirements is presented in Table
2.1. The Environmental Quality Performance Limits and
the Event and Action Plans (for construction noise only) are shown in Appendix
C and Appendix
D respectively.

Implementation of Environmental
Mitigation Measures
The Contractor is required to
implement mitigation measures listed in the latest valid EP and FEP(s) (where applicable),
EIA Report and EM&A Manual. During routine site inspections, the
Contractor's implementation of mitigation measures, if any, are to be inspected
and reviewed. A schedule of the implementation of mitigation measures
identified at the EIA stage is given in Appendix
E.
3.1
Monitoring Parameters, Frequency and
Duration
Following the requirements in the
EM&A Manual for noise, noise monitoring has to be carried out during the
construction phase. Continuous noise monitoring for the A-weighted levels Leq,
L10 and L90 is undertaken once per every week during
daytime hours (between 07:00 and 19:00) on normal weekdays.
Table 3.1 summarizes the monitoring parameters, frequency
and duration of air quality monitoring. The noise monitoring schedule during
the reporting month is presented in Appendix
F.

Originally, two construction noise
monitoring stations were proposed in the EM&A Manual, namely: STK03 (Block
1, Sha Tau Kok Estate) and STK05 (Village House at Sha Tau Kok). STK03 was
mainly selected for the construction works related to the SBF and the new
checkpoint in Sha Tau Kok, while STK05 was mainly selected for the removal of
the existing checkpoint at Shek Chung Au.
However, access to STK03 to perform
noise monitoring was not granted, therefore an alternative nearby location –
STK-DBD (HKPF Operation Base, Sha Tau Kok Division, Border District) – was
proposed by ET and agreed to by IEC and EPD. Baseline noise monitoring was
subsequently conducted at STK-DBD from 16 to 29 March 2010.
Currently, there is no solid
timetable or programme for the demolition works of the existing checkpoint at
Shek Chung Au, although the end of 2011 has been proposed as a possible
commencement date. This is subject to future confirmation of the demolition
programme by the Security Bureau and HKPF. No noise monitoring at STK05 has
been carried out at this stage.
As a result, only one noise impact
monitoring station is included in the current EM&A programme for Section 4.
The location of the agreed noise quality monitoring station is listed in Table
3.2 and shown in Figure 1.2.

¡ The Sound Level Meter was set on a
tripod at a height of at least 1.2 m above the ground.
¡ Façade measurements were made at the
monitoring locations.
¡ The battery condition was checked to
ensure the correct functioning of the meter.
¡ Parameters such as frequency
weighting, the time weighting and the measurement time were set as follows:
- frequency weighting: A
- time weighting: Fast
- time measurement: 5-minute intervals
(between 07:00 and 19:00); Leq (30 min) was determined by
calculating the logarithmic average of six Leq (5-min) data.
¡ Prior to and after each noise
measurement, the meter was calibrated using a Calibrator for 94 dB at 1
kHz. If the difference in the
calibration level before and after measurement was more than 1 dB, the
measurement would be considered invalid and have to be repeated after
re-calibration or repair of the equipment.
¡ During the monitoring period, the Leq,
L10 and L90 noise levels were recorded. In addition, any site observations and noise
sources were recorded on a standard record sheet.
3.5.2
Maintenance and Calibration
¡ The microphone head of the sound
level meter and calibrator is cleaned with soft cloth at quarterly intervals.
¡ The meter and calibrator are sent to
the supplier or Hong Kong Laboratory Accreditation Scheme (HOKLAS) laboratory
to check and calibrate at yearly intervals.
3.6
Results of Impact Monitoring
The measured construction noise levels, in
terms of Leq (30-min), during the reporting month are summarised in Table
3.5. Detailed
results, including general weather conditions and graphical presentations are
presented in Appendix K.

Note: All figures are rounded off to the
nearest whole number.
No exceedance of Action / Limit Levels for
construction noise was recorded.
No direct comparison between the measured noise
levels and the construction noise levels predicted in the EIA Report for this
Project was possible due to the minor nature of site works conducted during the
reporting month.
Wind data obtained from the nearest Hong Kong
Observatory monitoring station, at Ta Kwu Ling, covering all noise monitoring
days during the reporting month is included in Appendix K.
Environmental site inspections were
carried out on a weekly basis to monitor the proper implementation of environmental
pollution control and mitigation measures for Section 4. In the reporting
month, three monthly site inspections were carried out jointly by the ER,
Contractor, ET and IEC on 1, 22 and 31 December 2010, and additional weekly
site inspections were carried out by the ER, Contractor and ET on 7 and 16
December 2010. The EM&A schedule is presented in Appendix F.
Major findings provided jointly by
the ET and IEC during the joint monthly site inspections, and provided by ET
during the additional weekly site inspections, are summarised in Table 4.1. In general, the works site areas were found to
be in compliance with the environmental mitigation requirements listed in the
EM&A Manual and no adverse impacts were found.

Key Issues for the Next Reporting
Month
Based on the forecast major
construction works listed in Section 6.1, the key environmental issues to be considered in
December 2010 include:
¡ All plant and equipment to be
maintained to prevent any undue air emissions.
¡ Any excavated dusty materials or
stockpile of dusty materials should be covered entirely by impervious sheeting
or sprayed with water so as to maintain the entire surface wet, and recovered
or backfilled or reinstated within 24 hours of the excavation or unloading;
¡ All dusty materials should be
sprayed with water prior to any loading, unloading or transfer; and
¡ Every vehicle should be washed to
remove any dusty materials from its body and wheels before leaving the
construction sites.
¡ Noisy equipment and noisy activities
should be located as far away from the Noise Sensitive Receivers (NSRs) as is
practical;
¡ Unused equipment should be turned
off. Powered Mechanical Equipment (PME) should be kept to a minimum and the
parallel use of noisy equipment / machinery should be avoided;
¡ Adoption of Level 1 site-specific
direction mitigation measures (use of quiet plant and movable noise barrier)
for construction/demolition work undertaken at a distance of 60m or less to the
NSRs; and
¡ Regular maintenance of all plant and
equipment.
¡ No discharge of silty water into the
storm drain and drainage channel within and the vicinity of the site;
¡ Any construction plant which causes
pollution to the water system due to leakage of oil or fuel shall be removed
off-site immediately; and
¡ Excavated soil which needs to be
temporarily stockpiled should be stored in a specially designated area and
provided with a tarpaulin cover to avoid runoff into the drainage channels.
¡ Control measures should be taken at
the stockpiling area to prevent the generation of dust and pollution of
stormwater channels, fish ponds or river channels;
¡ Different types of waste should be
segregated, stored, transported and disposed of in accordance with the relevant
legislative requirements and guidelines; and
¡ Records of quantities of wastes
generated, recycled and disposal (with locations) shall be kept.
¡ Good site practices for controlling
the dust and water quality (avoid stockpiles adjacent to wetlands, covering the
stockpiles with impervious sheeting, control of vehicle speed, no discharge of
silty water to the rivers, streams and drainage channels); and
¡ Clear definition of works limit to
avoid impact on adjacent habitats.
¡ Retain trees that have high amenity
or ecology value and contribute most to the landscape and amenity of the site
and its immediate environs;
¡ Creation of precautionary area
around trees to be retained equal to half of the tree canopy diameter.
Precautionary area to be fenced;
¡ Prohibition of the storage of
materials including fuel, the movement of construction vehicles, and the
refuelling and washing of equipment including concrete mixers within the
precautionary area;
¡ Pruning of the branches of existing
trees identified for transplantation and retention to be based on the principle
of crown thinning maintaining their form and amenity value;
¡ The rectification and repair of
damaged vegetation following the construction phase to its original condition
prior to the commencement of the works or replacement using specimens of the
same species, size and form where appropriate to the design intention of the area
affected;
¡ All works affecting the trees
identified for retention and transplantation will be carefully monitored. This
includes the key stages in the preparation of trees, the implementation of
protection measures and health monitoring throughout the construction period;
and
¡ Construction site controls should be
enforced including the storage of materials, the location and appearance of
site accommodation and the careful design of site lighting to prevent light
spillage.
6.3
Monitoring Schedule for the Next
Reporting Month
The tentative schedule for
environmental monitoring in January 2011 is provided in Appendix F. Actual monitoring dates may change due to unforeseen
events such as inclement weather.
The construction phase and EM&A
programme for Section 4 commenced on 28 May 2010. EM&A was performed from 1
to 31 December 2010 during which some minor site works have commenced. All
monitoring and audit results in the reporting month were checked and reviewed.
Construction noise monitoring was
carried out in the reporting month. As no noise-related complaint was received
or follow-up by ET during the reporting month, no Action Level exceedance was
recorded. All noise monitoring results obtained complied with the Limit Level.
Environmental site inspections were
carried out five times during the reporting month. During the site audits,
recommendations on remedial actions were given to the Contractor for any
deficiencies identified.

runoff to the site. ¡ No discharge of silty water into the storm
drain and drainage channel within and the vicinity of the site. ¡ Any soil contaminated with chemicals/oils
shall be removed from site and the void created shall be filled with suitable
materials. ¡ Stockpiles to be covered by tarpaulin to
avoid spreading of materials during rainstorms; ¡ Suitable containers shall be used to hold
the chemical wastes to avoid leakage or spillage during storage, handling and
transport; ¡ Chemical waste containers shall be
labelled with appropriate warning signs in English and Chinese to avoid accidents. there shall also be clear instructions
showing what action to take in the event of an accidental; ¡ Storage areas shall be selected at safe
locations on site and adequate space shall be allocated to the storage area; ¡ Any construction plant which causes
pollution to the water system due to leakage of oil or fuel shall be removed
off-site immediately; ¡ Spillage or leakage of chemical waste to
be controlled by using suitable absorbent materials; ¡ Chemicals will always be stored on drip
trays or in bunded areas where the volume is 110% of the stored volume; ¡ Regular clearance of domestic waste
generated in the temporary sanitary facilities to avoid waste water
spillage. ¡ Temporary sanitary facilities to be provided for on-site workers during construction. |

Construction and
Demolition Materials Careful design, planning and good site management can minimize over-ordering and generation of waste materials such as concrete mortars and cement grouts. The design of formwork should maximize the use of standard wooden panels so to achieve high reuse levels. Alternatives such as steel formwork or plastic facing should be considered to increase the potential for reuse. The Contractor should recycle as much of the C&D materials as possible on-site. Proper segregation of waste on-site will increase the feasibility of certain components of the waste stream by the recycling contractors. Different areas of the worksite shall be designated for such segregation and storage wherever site conditions permit. Trip-ticket system should be employed to monitor the disposal of C&D material and solid at public filling facilities and landfills, and to control fly-tipping. Government has established a differentiated charging scheme for the disposal of waste to landfill, construction waste sorting facilities and public fill facilities. This will provide additional incentives to reduce the volume of waste generated and to ensure proper segregation of wastes. |

Chemical Waste For those processes which generate chemical
waste, it may be possible to find alternatives which generate reduced
quantities or even no chemical waste, or less dangerous types of chemical
waste. Chemical waste that is produced, as defined
by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation,
should be handed in accordance with the Code of Practice on the Packaging,
Handling and Storage of Chemical Waste as follows: Containers used for the storage of chemical
wastes should: ¡ 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 litres
unless the specification have been approved by the EPD; and ¡ display a label in English and Chinese in
accordance with instructions prescribed in Schedule 2 of the Regulations, The storage area for chemical wastes should: ¡ be clearly labelled and used solely for
the storage of chemical waste; ¡ be enclosed on at least 3 sides; ¡ have an impermeable floor and bunding, of
capacity to accommodate 110% of the volume of the largest container or 20% by
volume of the chemical waste stored in that area whichever is the greatest; ¡ have adequate ventilation; ¡ be covered to prevent rainfall entering
(water collected within the bund must be tested and disposed as chemical
waste if necessary); and ¡ be arranged so that incompatible materials
are adequately separated. Disposal of chemical waste should: ¡ be via a licensed waste collector; and ¡ be to a facility licensed to receive
chemical waste, such as the Chemical Waste Treatment Facility which also
offers a chemical waste collection service and can supply the necessary
storage containers, or ¡ to be re-user of the waste, under approval from the EPD. |

Design of Boundary Fence, 1.
Integrated
design approach – the boundary fence should integrated, as far as technically
feasible, with existing built structures such as existing road, footpath and
track and embankment of fishponds,
river and drainage channel as part of design mitigation measures to reduce
the potential cumulative impact of the proposed works. The location and
orientation of the police check points should be away from landscape and
visually sensitive areas such wetland, fishpond and agricultural field. 2.
Building
massing - the proposed use of simple responsive design for the built
structures with a low building height profile to reduce the potential visual
mass of the structure within a rural context. 3.
Treatment
of built structures - the architectural design should seek to reduce the
apparent visual mass of the facilities further through the use of natural
materials such as wooden frame, vertical greening or other sustainable
materials such as recycled plastic. 4.
Responsive
building and fence finishes - In terms of the proposed finishes natural tones
should be considered for the colour palette with non-reflective finishes are
recommended to reduce glare effect. The use of colour blocking on the
proposed fence could be used to break up the visual mass of the structure. 5.
Responsive
lighting design – Aesthetic design of architectural and track lighting with
following glare design measures: -
Directional
and full cut off lighting is recommended particularly for areas adjacent to
existing village to minimise light spillage. -
Minimise
geographical spread of lighting, only applied for safety and security
reasons; -
Limited
lighting intensity to meet the minimum safety and operation requirement; and - High-pressure sodium road lighting is recommended for more stringent light control reducing spillage and thus visual impacts. |

Compensatory
Planting Proposals – Given the works extent is largely limited along existing
roadside embankment to minimise impact to existing village settlements and
valuable landscape resources such as wetland, fishpond, stream course and
existing trees, and considered the importance of tree retention within the
works area, new tree planting will concentrate in selected new amenity areas
along the alignment, infilling between retained and transplanted trees. The
preliminary planting proposals for the proposed works include the planting of
some 357 new trees utilising a combination of mature to light standard sized
stock (i.e. approximately 15% of mature trees, 75% of standard trees, and 10%
light standard trees). These trees will be planted in woodland clumps and
small tree groups at strategic locations to de-emphasise the horizontality of
the fence alignment. Based on preliminary findings the proposed planting will
result in a compensatory planting ratio of 1:1 (new planting: trees
recommended for felling). This compares favourably with the report's
assertion that some 357 trees would be felled due to the proposed works. With
the proposed preservation of existing trees, transplantation of trees in
conflict with the proposals and the planting of new trees the project area
will contain approximately 2000 trees. Trees forming part of the new planting
will provide screening to neighbourhood villagers and will utilise species
