Executive Summary

Mott MacDonald Hong Kong Ltd. (“MMHK”) has been commissioned by Heng Shung Construction Co. Ltd.

to undertake the Environmental Team (ET) services to carry out environmental monitoring and audit

(EM&A) for both pre-construction and construction phases of the Proposed Comprehensive Development

at Wo Shang Wai, Yuen Long.

This is the 3rd

Quarterly EM&A Summary report and this report summarises the findings on EM&A during

the period from 1 November 2010 to 31 January 2011.

On 12 November 2010, the Contractor issued a letter on completion of construction of WRA with reference

to the EP Condition 3.3 to 3.5. In accordance with EP Condition 3.6, the evidence of completion has been

certified by the ET Leader and verified by the IEC before submitting to the Director of Environmental

Protection (the Director).

Exceedance of Action and Limit Levels

The Action levels of Air Quality (1-hr TSP) were exceeded on 7 Dec 2010 at the four monitoring stations

(ASR1, ASR2A, ASR3, ASR4). The summary of exceedance is provided in Section 2.1. Investigations on

the exceedance showed that the unfavourable wind direction on the date of exceedance may have carried

pollutants from Shenzhen and caused short term deterioration of air quality in the project area. The

exceedance was not considered to be related to the project.

There was no breach of Action or Limit levels for Noise (as Leq) in the reporting month.

Action and Limit Level exceedances of pH, DO, turbidity and SS were recorded at water quality monitoring

stations. The summary of measured water quality is presented in Section 2.3. Investigations on the

exceedance showed that the exceedances were not related to the Project and may have been due to

external factors including natural variations and other unknown factors such as pond fish culture activities

and high fish activities in the ditch.

Implementation of mitigation measures

Site audits were carried out on a weekly basis during the monitoring period to confirm the implementation

of environmental mitigation measures undertaken by the Contractor in the reporting period. The status of

implementation of mitigation measures in the site is shown in Appendix F.

Record of Complaints

There was no record of complaints received in the reporting period.

Future Key Issues

The major site works to be commissioned in the coming three months include installation of band drain, trial

embankment for ground improvement and site formation (filling). Potential environmental impacts due to

the construction activities, including air quality, noise, water quality, ecology and landscape and visual, will

be monitored.


iv


Environmental mitigation measures will be implemented on site as recommended and weekly site audits

will be carried out to ensure that the environmental conditions are acceptable.

1.5 Recommended Mitigation Measures

The EM&A programme followed the recommended mitigation measures in the EM&A manual. The EM&A

requirements as well as the summary of implementation status of the environmental mitigation measures

are provided in Appendix F. In particular, the following mitigation measures were brought to attention

during the site audits during the reporting period:

Air Quality

• All stockpiles should be covered by tarpaulin or kept wet by water spraying;

• All vehicles should be washed to remove any dusty materials before leaving the construction sites;

• the portion of road leading the construction site that is within 30m of a designated vehicle entrance

or exit should be kept clear of dusty materials;

• Sufficient water spraying should be provided at haul road to reduce dust emission; and

• Ensure proper functioning of the wheel wash facility.


3


Noise

• Mobile plant should be sited as far away from NSRs as possible;

• Plant known to emit noise strongly in one direction should be orientated to direct noise away from

the NSRs; and

• The construction activities should be better scheduled to reduce noise nuisance.

Water Quality

• Water accumulated in the site (including water inside drip trays) should be cleared frequently;

• Ensure proper functioning of the wastewater treatment facility;

• Silt and debris should be removed from the temporary drainage channel regularly; and

• Any soil contaminated with chemicals/oils shall be removed from site and the void created shall be

filled with suitable materials.

Waste management

• Reuse the excavated materials as far as practical to reduce the amount of waste disposal;

• Ensure drip trays are provided for chemical containers to prevent leakage or soil contamination;

• All plants and vehicles should be properly maintained to prevent oil leakage;

• Oil stains on soil should be cleared by disposal of contaminated soil; and

2.1 Air Quality Monitoring

Results and graphical plots of 1-hour TSP and 24-hr TSP at the four monitoring locations are summarised

in are shown in Appendix D. The Action levels of 1-hr TSP were exceeded for all the monitoring events on

7 December 2010 at the 4 air quality monitoring stations.

The weather conditions in the reporting period were generally fine and sunny with relatively lower humidity

and occasional strong wind. For details of wind speed and direction during the monitoring period, please

refer to the Monthly EM&A reports.

2.2 Construction Noise Monitoring

The construction noise monitoring results and graphical plots are shown in Appendix D. No exceedance

(Action/Limit Level) of construction noise was recorded in the reporting period.

2.3 Water Quality Monitoring

The water quality monitoring results and the graphical plots of the monitoring data are shown in Appendix

D.

Exceedances of pH, DO, turbidity and SS were observed. For MP1 to MP3, there were frequent

exceedances of action and limit levels for pH. There were a few occasions of exceedance of action and

limit levels of SS and turbidity at MP2 while two exceedances of limit levels of DO were found at MP3 in

December 2010. On the other hand, exceedances of pH were observed at MP4 to MP6 representing the

ditch at the north of the site from early December 2010 onward. For MP5, there was one occasion of

exceedance of action level of turbidity on 24 November 2010.

2.4 Ecological Monitoring

2.4.1 Monitoring of Birds

Monitoring was undertaken following the survey methodology in the EM&A Manual. The Wetland

Restoration Area (hereafter WRA) was also surveyed during the reporting period as the area became

accessible and site formation works for WRA has been completed. Low intensity monitoring of the WRA

was undertaken (on a monthly basis) to monitor faunal usage of the newly formed cells; monitoring

intensity will follow that outlined in the EM&A Manual at the completion of the WRA. A transect was

followed in the bird surveys (see Figure 2.1).

All bird species of conservation importance and/or wetland dependent were identified and enumerated.

Flying birds were not recorded unless they were foraging and associated with the habitat (such as swifts).

Further, notable bird observations during other surveys were also recorded. A summary of survey data is

provided in Appendix E.

A total of 42, 52 and 39 bird species (30, 34 and 21 in WRA) were recorded in the survey area in

November, December 2010 and January 2011 respectively. Among the birds surveyed in the WRA, 17, 27

and 18 bird species of conservation importance and/or wetland-dependence were recorded in November,

December 2010 and January 2011 respectively.

In January 2011, species prone to disturbance were also recorded regularly on-site; these include three

duck species and five ardeid species. It is also of note that high numbers of ardeids (comprising mainly

Little Egret and one Black-faced Spoonbill) were recorded roosting in one of the adjacent fish ponds (Pond

52), indicating that disturbance from the construction site was not an issue.

Species and numbers recorded in this survey period are typical of fish pond area during the winter months

indicating that birds in the area are not presently being adversely affected by the construction of the

Wetland Restoration Area.

2.4.2 Monitoring of Herpetofauna

One day-time herpetofauna survey was conducted in November 2010. No amphibian species or reptile

species were recorded in the survey period.

One Red-eared Slider Trachemys scripta was found in the ponds within the survey area during the bird

survey conducted on the 20 November. This species is widely disturbed in Hong Kong and is exotic to

Hong Kong.

A summary of the survey findings are provided in Appendix E.

2.4.3 Monitoring of Dragonfly and Butterfly

Monitoring of dragonflies and butterflies was conducted once in November 2010. A total of nine dragonfly

species and ten butterfly species were recorded, and eight dragonfly species and four butterfly species

were recorded in the WRA. All species recorded were common and widespread and recorded in low to very

low numbers.

No dragonfly and butterfly surveys were scheduled in the December 2010 and January 2011. A summary

of the survey findings are provided in Appendix E.

2.4.4 Monitoring of Mammal

Monitoring of mammal was conducted concurrently with other surveys. No mammals were recorded in the

survey period.

2.5 Landscape and Visual Monitoring

The audit was undertaken with references to the specific mitigation measures recommended in Section

10.2 of the EM&A Manual and the audit results are summarized as below:

Table 2.1: Construction Audit Summary on Landscape and Visual

Area of Works Items to be Monitored


6


Works Area The boundaries of the works area have been established on site in accordance

with the contract documents and approved plans (EP), and the limit of current

heavy construction activity is now confined to within the site hoardings (North

side of the site / access road) and the noise barriers (other sides of the site).

Minor works such as horticultural maintenance of the planting and transplanted

trees, and boundary fence repair was proceeding along the Royal Palms - Palm

Springs boundary.

No construction works were observed to have exceeded the site boundaries.

Moreover, no construction was carried out at the wetland restoration area after

15 November 2010.

Protection of all trees and woodland blocks to be retained

Trees to be retained within the site, located northeast boundary alongside

wetland restoration area, have been identified and protected by temporary

protective fencing.

Streams The works site is encircled by a berm to intercept surface water and prevent it

from washing off into any of the neighboring sites. Surface water is collected

within the site in a temporary drainage channel. Gravels beds and barriers have

been installed to filter site runoff, sedimentation tanks provided to enable

primary treatment before discharge to mains drains.

Clearance of existing vegetation

Site clearance was completed prior to the commencement of construction. A

bed of existing Phragmites reeds which have been retained within a fenced off

area at the centre of the site and some reed clumps have been reused in the

vegetation of the wetland restoration area.

Transplanting of trees

Tree transplanting has been completed, with the trees relocated to various

points within the planting strip along the southern boundary of the site, outside

the noise barrier. The trees continue to re-establish well.

Topsoil stripping Suitable pond bund and pond bottom material excavated and stockpiled from

the original site has now been re-used in the formation of the wetland areas.

Active dust suppression measures are still being adopted along internal site

access tracks.

New buildings No new permanent buildings have yet been constructed on site.

Boundaries Hoardings have been erected along most of the boundaries of the site.

Installation of new fence between the future residential sites and the constructed

wetland area is complete. Fence has been being painted green to match with

the surrounding vegetated environment.

Noise Barrier Noise barriers have been installed along the southern and western boundaries

of the site in accordance with the contract requirements.

The noise barrier design complies with the mitigation requirements, with upper 6

to 7m portion of the barrier being made from a translucent material with green

tinted (to match with the environment). Supporting GMS structure, likewise, has

been painted green.

Night-time lighting No night-time works were reported to have been carried out during the

monitoring period.

Landscape and wetland treatments

Continuous belt of screen planting along the southern and western boundaries

of the site has been completed. The formation, soiling and water control

structures for all cells of the wetland restoration area has been completed. Rain

water has partially filled some wetland cells. The clumps of Phragmites australis

reeds from the original site have been successively translocated to the edge of

the ponds in wetland restoration area.

No construction was carried out at the wetland restoration area after 15

November 2010.

Soiling The soiling for the advance planting strip has been completed. Some bricks

have been installed to create a stronger edge of planting bed and to prevent soil

erosion. The soil placement and grading for the wetland restoration area is

complete.

Plant supply The plant material used for the Advance Planting Strip along the southern and

western boundaries of the site are all common species and came from

commercial sources.

Details of the procurement of special plant material for the wetland areas are to

be provided in Spring 2011, when nursery supplies become available.

Planting The total number of trees that will reach a minimum of 10m in the advance

planting strip meet the contract requirements. The tree species are all from the

approved list. This planting should achieve the required screening effect.

Health condition of recently transplanted trees (Eucalyptus) should be monitored

closely and identified die-back trees may need to be replanted.

Overhanging trees from adjacent properties had been cut back to allow more

light to the shrubs within the Advance Planting Strip. The overhanging trees will

need to be pruned regularly if situation is allowed. Replacement or repairing

works should be carried for those shrubs of poor health.

Establishment Works

The advance planting, the compensatory planting and the transplanted trees

have not yet been hand over for maintenance, the planting works are under

supervision onsite to ensure that the requirements of the approved planting

proposal are met. The advance planting is currently being maintained by the

landscape sub-contractor.

3.1 Site Inspection

The ET had carried out construction phase weekly site inspections on 3, 10, 19 and 26 November 2010; 1,

10, 15, 21 and 30 December 2010; and 5, 12, 19, 26 and 31 January 2011. All observations have been

recorded in the site inspection checklist and passed to the Contractor together with the appropriate

recommended mitigation measures where necessary.

3.2 Solid and Liquid Waste Management Status

The Contractor has been registered as a chemical waste producer for the Project. Construction and

demolition (C&D) material sorting was carried out on site. A sufficient number of receptacles were available

for general refuse collection.

As advised by the Contractor, 0 tonnes C&D material were generated on site and disposed off at Public Fill

Reception Facilities at Tuen Mun Area 38 during the period. No metals was generated and collected by

registered recycling collector. No paper cardboard packing and plastic were generated on site and

collected by registered recycling collector. No chemical waste was generated and collected by licensed

chemical waste collector. 22.3 tonnes of other types of wastes (e.g. general refuse) was generated on site

and disposed of at North East New Territories (NENT) Landfill.

The Contractor is advised to maintain on site waste sorting and recording system and maximize

reuse/recycling of C&D wastes.

4.1 Record on Non-compliance of Action and Limit Levels

4.1.1 Record of Non-compliance

The Action levels of 1-hr TSP were exceeded for all the monitoring events on 7 December 2010 at the 4 air

quality monitoring stations.

There is no breach of Action or Limit Levels for Noise monitoring in the reporting period.

Exceedances of Action and Limit Levels were recorded for Water Quality at MP1, MP2, MP3, MP4, MP5

and MP6 on different monitoring dates.

Exceedances of pH, DO, turbidity and SS were observed. For MP1 to MP3, there were frequent

exceedances of action and limit levels for pH. There were a few occasions of exceedance of action and

limit levels of SS and turbidity at MP2 while two exceedances of limit levels of DO were found at MP3 in

December 2010. On the other hand, exceedances of pH were observed at MP4 to MP6 representing the

ditch at the north of the site from early December 2010 onward. For MP5, there was one occasion of

exceedance of action level of turbidity on 24 November 2010.

4.1.2 Constructional Impacts on Water Quality

In order to determine the constructional impacts on water quality, the suspended solids level, which is a

good indicator of the quality of effluent from construction site, is selected for assessment. The average

value of suspended solids (SS) for water quality monitoring stations (MP1 – MP6) during baseline

monitoring and construction phase monitoring for the reporting period are listed in Table 4.1 below.

Table 4.1: Comparison of monitoring data of Suspended Solids

Average levels of Suspended Solids (mg/L)

Monitoring Stations During Baseline Monitoring

During Construction Phase Monitoring for the reporting period

Within 130% of mean value of Baseline data?

MP1 103.5 45.9 Yes

MP2 60.1 53.5 Yes

MP3 49.5 20.5 Yes

MP4 36.9 24.1 Yes

MP5 47.7 28.8 Yes

MP6 54.1 29.3 Yes

The average levels of suspended solids during the reporting period were within 130% of the baseline

values. Although there were exceedances of water quality parameters, the above statistics show that the

water quality during the reporting period has not significantly worsen when compared with the baseline

condition.

It was noted that during the reporting period, all the water quality parameters monitored have been

influenced by the natural environment and other external factors and exceedances of criteria were resulted.

The exceedances have been investigated and are described in below section.

4. Report on Non-compliance and Complaints

4.1.3 Exceedance Investigations

Air Quality

From investigation, the Contractor implemented air quality mitigation measures as recommended in EIA

report which include paving the vehicle washing area and site entrance, and keeping clear of the portion of

road leading the construction site from dusty materials, limiting vehicle speed to below 10 kph except on

completed access roads, and washing every vehicle to remove any dusty materials from its body and

wheels before leaving the construction sites. During the dry season, the Contractor has also made use of

the excavated fish pond clay to mix with the other imported soil materials to form the top layer of the works

area. The mixed soil layer was able to maintain higher moisture content and it generated less fugitive dust

from observations of the site inspection. In addition, water spraying has been provided by the Contractor at

various locations in the site on 7 Dec 2010 from photo record, including works area and haul road, to

further suppress dust.

The possible causes of exceedances have been investigated and reported to the IEC during construction

phase monitoring. From the record of the Hong Kong Observatory, there was moderate to strong wind on 7

Dec 2010. The prevailing wind direction became north to northeast starting from 6 Dec 2010 and the

direction was unchanged at the time of monitoring. Due to the close proximity of the site to the border with

mainland China and the unfavourable wind direction, it was believed that the wind blowing from north has

carried suspended particulates from Shenzhen and caused a short term deterioration of air quality. Record

of 24-hr TSP on 7 Dec 2010 showed that the average daily dust level remained at normal level (the 24-hr

TSP ranged from 79 to 93 µg/m3 for the 4 stations).

Consider the mitigation measures undertaken and the adverse wind condition, the exceedances were

considered not due to construction works.

Water Quality

From investigation, the Contractor has implemented water quality mitigation measures as recommended in

the EIA report, including the provision of temporary drainage facility and associated treatment facility. Sand

bags are in place in the temporary drainage channel to enhance the desilting efficiency. The Contractor

further enhanced the water quality mitigation measures by erecting several segments of rock bunds at the

discharge outlet to avoid site runoff draining directly to the northern ditches.

The possible causes of exceedances have been investigated and reported to the IEC during construction

phase monitoring. The exceedance investigations have also been included in the monthly EM&A report and

some of them are extracted and summarised in Table 4.1. The causes of some of the exceedances were

unknown but all of them were considered not related to the project. For detail, please refer to the previous

monthly EM&A reports.

Table 4.2: Summary of exceedance investigations

Descriptions of exceedances

Possible causes Exceedance related to project?

Exceedance of pH at MP1, MP2

The exceedance may have been caused by natural variations or other unknown factors.

No, as there was no direct discharge from the site to the ditch where MP1 and MP2 are located.

Exceedance of turbidity and SS on 6 and 15 Dec 2010 and turbidity on 22

The exceedance may have been caused by natural variations or other unknown factors such as high fish activities.

Ditto.


11


Descriptions of exceedances

Possible causes Exceedance related to project?

Dec 2010 at MP2

Exceedances of pH and DO at MP3 in Dec 2010

The exceedance maybe due to natural variation or other unknown factors such as pond fish culture activities.

No, noting that the fish pond (MP3) was being separated from the construction site by the WRA since November 2010.

Exceedance pH at MP4, MP5 and MP6

The exceedance may have been caused by natural variations or other unknown factors.

No, as there was also only small amount of site runoff generated and discharged in the dry season and considered the similar or lower pH compared with other monitoring stations.

Exceedance of turbidity at MP5 on 24 Nov 2010

The increase in turbidity at MP5 was due to some unknown factors.

No, since SS was not exceeded.

Conclusively, all of the exceedances were caused by external factors including natural variation and other

unknown factors such as pond fish culture activities. Moreover, as noted by monitoring team during on-site

sampling, no direct muddy water discharge was observed from the site. The exceedances were considered

not due to construction works.

4.2 Record on Environmental Complaints received

No environmental complaint was received this month.

4.3 Follow-up actions taken

Although it is considered that the exceedances were not related to the Project, the Contractor was

reminded to implement the air and water quality mitigation measures in accordance with the

recommendation stated in Section 3.6.1 and 5.6.1 – 5.6.4 of the EIA Report respectively as far as

practicable and regular spot check would be conducted on the nearby discharge by Contractor and inform

ET for investigation.

During the dry season, the Contractor has made use of the excavated fish pond clay to mix with the other

imported soil materials to form the top layer of the works area. The mixed soil layer was able to maintain

higher moisture content and it generated less fugitive dust from observations of the site inspection.

To cater for the site runoff in the previous months, the Contractor has further enhanced the water quality

mitigation measures by erecting several segments of rock bunds at the discharge outlet to avoid site runoff

draining directly to the northern ditches.

It was also advised that the operation condition of the Wastewater Treatment Facilities should be checked

regularly to ensure proper functioning of the plant and good quality of effluent discharge.

5.1 Construction Works for the Coming Months

The major site works to be commissioned in the coming three months include:

� Installation of band drain;

� Trial embankment for ground improvement; and

� Site formation (Filling)

5.2 Key Issues for the Coming Months

Key issues to be considered in the coming three months include:

� Generation of dust from activities on-site (esp. stockpiling for Trial Embankment);

� Noise impact from operating equipment and machinery on-site;

� Generation of site surface runoffs and wastewater from activities on-site;

� Sorting, recycling, storage and disposal of general refuse and construction waste from activities on-

site; and

� Management of chemicals and avoidance of oil spillage on-site.

5.3 Conclusions and Recommendations

5.3.1 Conclusions

The EM&A programme as recommended in the EM&A manual has been undertaken in the reporting

period.

Monitoring of Air Quality, Noise, Water Quality, Ecology and Landscape and Visual impacts due to the

Project was under way. In particular, the 1-hr TSP, 24-hr TSP, noise level (as Leq) and water quality

parameters (such as pH, DO and SS) under monitoring have been checked against established Action and

Limit levels.

The Action levels of Air Quality (1-hr TSP) were exceeded on 7 Dec 2010 at the four monitoring stations.

Investigations on the exceedance showed that the unfavourable wind direction on the date of exceedance

may have carried pollutants from Shenzhen and caused short term deterioration of air quality in the project

area. The exceedance was not considered to be related to the project.

There was no breach of Action or Limit levels for Noise (as Leq) in the reporting month.

Action and Limit Level exceedances of pH, DO, turbidity and SS were recorded at water quality monitoring

stations. However, Investigations on the exceedance showed that the exceedances were not related to the

Project and may have been due to external factors including natural variations and other unknown factors

such as pond fish culture activities and high fish activities in the ditch.

Waste Management – Recommended Mitigation Measures Waste Management Mitigation Measures during construction Implementation Status

Site Clearance Waste

• The major construction works of Wo Shang Wai is in the development of residential buildings and other associated facilities (club house, tennis courts, etc). The amount of site clearance works will be limited with the exception of the excavated materials. The thin layer of vegetation removed can be stored and reused for landscaping.

�

Excavated Materials The intention is to maximize the reuse of the excavated materials on-site as fill materials.

�

Imported Filling Material The excavated/imported filling material may have to be temporarily stockpiled on-site for the construction of road embankment and foundation of viaduct substructure. Control measures should be taken at the stockpiling area to prevent the generation of dust and pollution of stormwater channels. However, to eliminate the risk of blocking drains in the wet season, it is recommended that stockpiling of excavated materials at during wet season should be avoided as far as practicable.

N/A

Construction and Demolition Materials Careful design, planning and good site management can minimise over-ordering and generation of waste materials such as concrete, mortars and cement grouts. The design of formwork should maximise the use of standard wooden panels so that high reuse levels can be achieved. Alternatives such as steel formwork of plastic facing should be considered to increase the potential for reuse.

�

The Contractor should reuse any C&D material on-site. C&D waste should be segregated and stored in different containers to other wastes to encourage the re-use or recycling of materials and their proper disposal.

�

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.

N/A

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

N/A

• to be reuser of the waste, under approval from the EPD. N/A

- 4 -


General Refuse Should be stored in enclosed bins or compaction units separate from C&D and chemical wastes. The Contractor should employ a reputable waste collector to remove general refuse from the site, separate from C&D and chemical wastes, on a regular basis to minimise odour, pest and litter impacts. Burning of refuse on construction sites is prohibited by law.

P

Disposal of Excavated Sediment at Sea

The requirements and procedures for excavated sediment disposal are specified under the ETWB TCW No. 34/2002 and PNAP 252. The management of the excavation, use and disposal of sediment is monitored by Fill Management Committee, whilst the licensing of marine dumping is the responsibility of the Director of Environmental Protection (DEP).

N/A

The excavated sediment would be loaded onto barges or other appropriate vessel and transported to the designated marine disposal site. Category L sediment and Category M sediment passing the biological test would be suitable for disposal at a gazetted open sea disposal ground. Category M sediment failing the biological test and Category H sediment passing the biological test would require confined marine disposal.

N/A

During transportation and disposal of the dredged sediment, the following measures should be taken to minimize potential impacts on water quality: -

N/A

• Bottom opening transport vessels should be fitted with tight fitting seals to prevent leakage of material. Excess material should be cleaned from the decks and exposed fittings of vessels before the vessel is moved.

N/A

• Monitoring of the barge loading should be conducted to ensure that loss of material does not take place during transportation. Transport barges or vessels should be equipped with automatic self-monitoring devices as specified by the DEP.

N/A

Ecology – Recommended Mitigation Measures Ecology Mitigation Measures during construction Implementation Status

Clear Definition of Site Limit

Clear definition of the site limit should be provided in order to minimize and confine the disturbance during the construction period, especially the northern limit of the Site which is adjacent to fishponds within the Conservation Area (CA) zone and are considered to be ecological sensitive receivers.

During wetland construction stage the WRA boundary will be delineated using a temporary hoarding in order to reduce disturbance to off-site habitats and wildlife. During the establishment phase this hoarding will be replaced with a 1 m high chain-link fence in order to reduce disturbance to the WRA through access by humans and dogs, and a hoarding will be established around the residential construction site.

�

Dust and Noise Suppression and Avoidance of Water Pollution

Good site practices of dust and noise suppression should be strictly implemented to ensure that disturbance is minimized to acceptable levels. Mitigation measures for the off-site disturbance impacts on the fishponds in the CA include hoarding at the northern site boundary during construction of the WRA to reduce noise and dust impacts to the adjacent habitats. Through the use of quieter plant and temporary/movable noise barriers, the noise level would be reduced significantly to an acceptable level. Hoarding at the northern boundary should be replaced with a 1 m high chain-link fence following construction and the WRA will then act as a buffer between the existing wetland areas and the residential part of the site until construction is completed. Hoarding will be retained between the WRA and ongoing construction work to avoid visual disturbance and reduce noise and dust emissions. Pollution of watercourses and sedimentary runoff will be minimized by good site practice, especially the containment of water and sediment within the site for removal.

These standard noise and air and water quality site practices are considered to be effective measures for minimizing the disturbance impact during the construction period.

�

Planning of Construction Schedule

- 5 -


The construction of the proposed project should be scheduled in phases. Because mitigation is preferably carried out in advance of the main works rather than after the completion of works, the construction of the WRA will commence at the start of the project. Construction work within the WRA is scheduled to take place in a single wet season, followed by 1.5 years of wetland establishment. During the wetland establishment period no noisy work will be undertaken within the WRA to minimize the disturbance to off-site habitats and wildlife.

�

Reusing Onsite Materials

Soil and plants on-site should be reused (e.g. used as fill material) as far as practical. Stock piles of these reusable materials should be stored in an appropriate area on-site. In particular, the re-use of the wetland soils and topsoil should be considered.

�

Construction of the Wetland Restoration Area The WRA will be operational within 2.5 yrs from the commencement of construction (1 year for site formation and 1.5 years for establishment) and will compensate for the predicted ecological impacts of the proposed development.

�

Landscape and Visual – Recommended Mitigation Measures Landscape and Visual Mitigation Measures during construction Implementation Status

CM1- The construction area and contractor’s temporary works areas should be minimised to avoid impacts on adjacent landscape.

�

CM2 - Screening of construction works by hoarding / noise barriers. �

CM3 - Reduction of construction period to practical minimum. �

CM4 - Topsoil, where identified, should be stripped and stored for re-use in the construction of the soft landscape works, where the soil material meets acceptable criteria and where practical. The Contract Specification shall include storage and reuse of topsoil as appropriate.

�

CM5 - Hydroseeding or sheeting of soil stockpiles with visually unobtrusive material (in earth tone).

�

CM6 – Advance screen planting of noise barriers �

CM7 - Control night-time lighting and glare by hooding all lights. �

CM8 - Ensure no run-off into streams adjacent to the Project Area. �

CM9 - Protection of existing trees on boundary of site shall be carefully protected during construction. Detailed Tree Protection Specification shall be provided in the Contract Specification. Under this specification, the Contractor shall be required to submit, for approval, a detailed working method statement for the protection of trees prior to undertaking any works adjacent to all retained trees, including trees in contractor’s works areas. (Tree protection measures will be detailed at S16 and Tree Removal Application stage).

�

CM10 - Trees unavoidably affected by the works shall be transplanted where practical. Trees should be transplanted straight to their destinations and not held in a nursery. A detailed Tree Transplanting Specification shall be provided in the Contract Specification, if applicable. Sufficient time for necessary tree root and crown preparation periods shall be allowed in the project programme.
