1 Introduction

1.1 Background

In March 2005, the Project Proponent, Profit Point Enterprises Limited, acquired the development site at Wo Shang Wai in Yuen Long. An Environmental Impact Assessment (EIA) was then carried out and approved under the EIA Ordinance (EIAO), and the Environmental Permit (EP-311/2008) for construction of the comprehensive development in Wo Shang Wai was first granted by EPD on 9 September 2008 and has been subsequently varied, with the current version (EP-311/2008/D) issued by EPD on 20 March 2013.

The Project involves the residential development and associated infrastructure and wetland restoration area and linear landscape area. The construction works under the Environmental Permit commenced on 12 May 2010. The site formation construction works of the Wetland Restoration Area (hereafter WRA) were completed on 15 November 2010, while the 30-month establishment period of the WRA was concluded in August 2012 – this indicated that planting works as scheduled in the approved Wetland Restoration and Creation Scheme (WRCS; Nov 2009) was complete, except along the western and southern boundary where the planting is affected by the existing site boundary and noise barrier, and for which a Variation to Environmental Permit (EP-311/2008/C) to defer planting at the location was approved. The current valid EP (EP-311/2008/D) includes specific mitigation measures to minimise certain identified noise impacts during the operation phase.

Mott MacDonald Hong Kong Ltd. (“MMHK”) has been commissioned by the Contractor, 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.

According to the EP Condition 4.5, the monthly EM&A Report shall be submitted to the Director within two weeks after the end of the reporting month. This report summarises the findings during the period from 1 to 31 August 2014.

2.2.4 Monitoring Methodology

2.2.4.1 24-hour TSP Monitoring

Installation

The HVS was installed in the vicinity of the air sensitive receiver. The following criteria were considered in the installation of the HVS.

A horizontal platform with appropriate support to secure the sampler against gusty wind was provided.
The distance between the HVS and any obstacles, such as buildings, was at least twice the height that the obstacle protrudes above the HVS.
A minimum of two metres separation from walls, parapets and penthouse was required for rooftop sampler.
A minimum of two metres separation from any supporting structure, measured horizontally was required.
No furnace or incinerator flues or building vent were nearby.
Airflow around the sampler was unrestricted.
The sampler has been more than 20 metres from any drip line.
Permission was obtained to set up the samplers and to obtain access to the monitoring stations.
A secured supply of electricity is needed to operate the samplers.

Preparation of Filter Papers

· Glass fibre filters, were labelled and sufficient filters that were clean and without pinholes were selected.

· All filters were equilibrated in the conditioning environment for 24 hours before weighing. The conditioning environment temperature was around 25 °C and not variable by more than ±3 °C with relative humidity (RH) < 50 % and was not variable by more than ±5 %. A convenient working RH was 40 %.

Field Monitoring

· The power supply was checked to ensure the HVS works properly.

· The filter holder and the area surrounding the filter were cleaned.

· The filter holder was removed by loosening the four bolts and a new filter, with stamped number upward, on a supporting screen was aligned carefully.

· The filter was properly aligned on the screen so that the gasket formed an airtight seal on the outer edges of the filter.

· The swing bolts were fastened to hold the filter holder down to the frame. The pressure applied should be sufficient to avoid air leakage at the edges.

· The shelter lid was closed and was secured with the aluminium strip.

· The HVS was warmed-up for about 5 minutes to establish run-temperature conditions.

· A new flow rate record sheet was set into the flow recorder.

· The flow rate of the HVS was checked and adjusted at around 1.1 m³/min. The range specified in the EM&A Manual was between 0.6-1.7 m³/min.

· The programmable timer was set for a sampling period of 24 hrs + 1 hr, and the starting time, weather condition and the filter number were recorded.

· The initial elapsed time was recorded.

· At the end of sampling, the sampled filter was removed carefully and folded in half length so that only surfaces with collected particulate matter were in contact.

· It was then placed in a clean plastic envelope and sealed.

· All monitoring information was recorded on a standard data sheet.

· Filters were sent to a HOKLAS accredited laboratory for analysis.

Maintenance and Calibration

· The HVS and its accessories are maintained in good working condition, such as replacing motor brushes routinely and checking electrical wiring to ensure a continuous power supply.

· HVSs were calibrated at two-month intervals.

· Calibration records for HVSs are shown in Appendix E.

2.2.4.2 1-hour TSP Monitoring

Field Monitoring

The measuring procedures of the 1-hour dust meter are in accordance with the Manufacturer’s Instruction Manual as follows:

· Set POWER to “ON”, push BATTERY button, make sure that the meter’s indicator is in the range with a red line and allow the instrument to stand for about 3 minutes (Then, the air sampling inlet has been capped).

· Push the knob at MEASURE position.

· Push “O-ADJ” button. (Then meter’s indication is 0).

· Push the knob at SENSI ADJ position and set the meter’s indication to S value described on the Test Report using the trimmer for SENSI ADJ.

· Pull out the knob and return it to MEASURE position.

· Push “START” button.

Maintenance and Calibration

· The 1-hour dust meter would be checked at 3-month intervals and calibrated at 1-year intervals throughout all stages of the air quality monitoring.

· Calibration records for direct dust meters are shown in Appendix E.

2.3 Construction Noise

2.3.1 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 L_eq, L₁₀ and L₉₀ is undertaken once per every week.

Table 2.4 summarizes the monitoring parameters, frequency and duration of air quality monitoring.

Table 2.4: Noise Monitoring Parameters, Frequency and Duration

Monitoring Stations	Parameter	Frequency and Duration
NSR1, NSR3, NSR5, NSR7	L_eq, L₉₀ & L₁₀	Once every week

2.3.2 Monitoring Locations

The four noise quality monitoring stations were established in the EM&A manual and were slightly adjusted during the baseline monitoring phase. Locations of the agreed noise quality monitoring stations are listed in Table 2.5 and as shown in Figure 2.2.

2.3.4 Monitoring Methodology

Field Monitoring

The Sound Level Meter was set on a tripod at a height of at least 1.2 m above the ground.
Façade and free-field 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: 30 minutes intervals (between 07:00 and 19:00)

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 has to be repeated after re-calibration or repair of the equipment.
During the monitoring period, the L_eq, L₁₀ and L₉₀ were recorded. In addition, any site observations and noise sources were recorded on a standard record sheet.

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 HOKLAS laboratory to check and calibrate at yearly intervals.
Calibration records are shown in Appendix E.

Biochemical Oxygen Demand (BOD), mg/L	In house method based on APHA 5210B; ALS Method Code: EP-030

All in-situ monitoring instruments were checked, calibrated and certified by a laboratory accredited under HOKLAS or any other international accreditation scheme before use.

Dissolved Oxygen (DO), temperature and pH measuring equipment

A portable, weatherproof multiparameter instrument (YSI Professional Plus) was used in the monitoring. It can be capable for measuring dissolved oxygen (DO), pH, and temperature simultaneously with the following limits:

· a dissolved oxygen level in the range of 0-50 mg/L and 0-500 % saturation;

· a temperature of -5 to 45 degree Celsius; and

· pH value of 0-14 with 0.1 as the base unit.

Turbidity Measurement Instrument

Portable and weatherproof turbidity meter (HACH model 2100Q) was used during impact monitoring. It has a photoelectric sensor capable of measuring turbidity between 0-1000 NTU. Response of the sensor was checked with certified standard turbidity solutions before the start of measurement.

Global Positioning System

A hand-held GPS navigator (Garmin eTrex Vista) was used to identify the designated monitoring stations prior to water sampling.

Suspended Solids and BOD Measurements (Sample Containers and Storage)

Water samples for SS analysis were stored in high density polythene bottles with no preservative added, packed in ice (cooled to 4^oC without being frozen), delivered to the laboratory, and analysed as soon as possible after collection. Analysis was carried out in a HOKLAS accredited laboratory.

2.4.4 Detection Limit

The limits of detection for the in-situ and laboratory measurements are shown in Table 2.11.

Table 2.11: Detection Limits for Water Quality Determinants

Determinant	Limit of Detection
Dissolved Oxygen	0.1 mg/L
Temperature	0.1 degree Celsius
pH	0.01 unit
Turbidity	0.1 NTU
Suspended Solids	1 mg/L
BOD	2 mg/L

2.4.5 Monitoring Methodology

In situ measurement

All pH meters, DO/temperature meters had been checked and calibrated prior to use. Standard buffer solution of at least two pH levels (either pH 4 and pH 7, or pH 7 and pH 10) had been used for calibration of the instrument before and after use.

DO meters had been calibrated by a laboratory accredited under HOKLAS or any other international accreditation scheme, and subsequently re-calibrated at three-monthly intervals throughout all stages of the water quality monitoring. Responses of sensors and electrodes had been checked with certified standard solutions before each use. Wet bulb calibrations for all DO meters had been carried out before measurement at each monitoring location. For the on-site calibration of field equipment, BS 127:1993, "Guide to field and on-site test methods for the analysis of waters" had been observed.

Measurements shall be at three water depths, namely, 1m below water surface, mid-depth and 1m above stream bed/pond bed, except where the water depth less that 6m, the mid-depth station maybe omitted. Should the water depth be less than 3m, only the mid-depth station will be monitored.

Replicates in-situ measurements and samples collected from each independent monitoring event are required for all parameters to ensure a robust statistically interpretable dataset.

Water Samples Preparation and Analysis

For collection of water sampling within the water courses, a 500ml clean plastic beaker was used. After collection, the water samples were stored in high-density polythene bottles. The sample container was rinsed with a portion of the water sample. The water sample was then transferred to the container, labelled with a unique sample ID and sealed with a screw cap. The water samples were stored in a cool box maintained at 4^oC. The water samples were then delivered to a local HOKLAS-accredited laboratory (ALS) on the same day for analysis.

The testing methods of testing parameters as recommended by EIA or required by EPD, with the QA/QC results are in accordance with the requirement of HOKLAS or international accredited scheme.

The calibration certificates for equipment used for in-situ monitoring of water quality are attached in Appendix E.

3.2.3.1 Exceedance Investigation and Findings

During August 2014, two exceedances of DO were observed at MP3. No exceedance was observed at MP4, MP5 and MP6.

The Event and Action Plan in Appendix D was followed under these cases of exceedances.

From investigation, construction activities during the period of exceedance included mainly site formation and foundation work, as well as pond drainage management in the Wetland Restoration Area (to lower the water level and remove unwanted species in the pond). It was observed that 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 and installing a barrier at the discharge outlet to desilt and divert site runoff to sedimentation tanks and wastewater treatment facilities (Aquased), which will ensure all site runoff is treated to satisfactory quality before discharging into the northern ditches.

Exceedances of DO at MP3

During the reporting month at MP3, exceedance of the Action/Limit Level of DO was observed on 10 monitoring dates. As understood, the fish pond near the site (represented by MP3) was being separated from the construction site by the WRA since November 2010, so the exceedances were not considered to be related to the construction activities. The exceedances of DO may be due to external factors such as pond fish culture activities which were out of the control of the project.

Conclusion

As a result, the abovementioned exceedances are unlikely to be due to the construction works and therefore not considered to be related to the project.

4 Ecological Monitoring

4.1 Monitoring of Birds

This report documents surveys conducted in the Survey Area between 1 and 31 August 2014. The Wetland Restoration Area (WRA) is also surveyed as the area is accessible and site formation works for WRA has been completed. The updated survey transect is provided in Figure 4.1. Dates and ecological surveys conducted during this period are summarised in Appendix H.

Monitoring was undertaken following the survey methodology in the EM&A Manual. A transect was followed in the bird surveys (see Figure 4.1). All bird species were identified to species and all bird species of conservation importance and/or wetland dependent were enumerated and recorded to the habitats in which they were observed. Flying birds were not recorded unless they were foraging and/or associated with the habitat (such as swifts). Further, notable bird observations during other surveys were also recorded.

Bird surveys were conducted on a weekly basis. A total of 31 bird species were recorded in the Survey Area (excluding the WRA), 18 of which were species of conservation importance and/or wetland-dependence. Within the WRA, 29 bird species were recorded, 13 of which were species of conservation importance and/or wetland-dependent species, including two of the target species (i.e. Little Egret, Chinese Pond Heron) were recorded in regular survey. The WRA continues to attract a number of species of conservation importance, including Yellow Bittern, Ixobrychus sinensis and Wood Sandpiper, Tringa glareola, in regular survey and additional night search. These species are listed by Fellowes et al. as of “Local Concern” in 2002.

4.2 Monitoring of Herpetofauna

One day time and one night time herpetofauna survey were conducted in the period. No amphibian species and reptile species were recorded in the Survey Area (excluding the WRA) in regular survey but one amphibian species was recorded in the Survey Area (excluding the WRA) in additional search. No amphibian species and reptile species were recorded within the WRA in regular survey and additional search.

A summary of the survey findings is provided in Appendix J.

4.3 Monitoring of Dragonflies and Butterflies

Odonatas and butterflies surveys were conducted on a bi-weekly basis according to the EM&A Manual. Six odonata species and no butterfly species were recorded in the Survey Area (excluding the WRA). Within the WRA, ten odonata species were recorded, while two butterfly species were recorded.

A summary of the survey findings is provided in Appendix J.

4.4 Monitoring of Mammals

Monitoring of mammals was conducted concurrently with other surveys. No mammals were recorded in the Survey Area nor within the WRA during regular survey and additional night search.

A summary of the survey findings is provided in Appendix J.

4.5 Monitoring of Water Quality

The pH of Cell 1, 2 and 4 excess the Action Level during the reporting period. Monitoring data are presented in Appendix K.

4.6 Management Activities

4.6.1 Vegetation Management

Removal of exotic vegetation in all cells was undertaken; these included but not limited to Ipomoes sp., Mikania sp., Mimosa sp., Pennisetum sp. and Typha sp..

Vegetation management activities undertaken at the site primarily involved watering of plants, weeding and grass cutting.

4.6.2 Wildlife Management

Removal of Golden Apple Snail was undertaken on an “as-seen” basis.

All sighted Red Fire Ant nests were treated with approved pesticide.

4.7 Summary

Ecological monitoring during August 2014 was carried out according to the survey methodology and frequency outlined in the EM&A Manual.

Summary of survey findings is listed in Table 4.1 below:

Table 4.1: Summary of Ecological Monitoring in WRA and Survey Area

Species	Survey Area (excluding WRA)	WRA
Birds (total)	31	29
Birds (of conservation importance and/or wetland-dependence)	18	13
Amphibians	1	0
Reptiles	0	0
Mammals	0	0
Odonates	6	10
Butterflies	0	2

Survey findings indicate that the ponds within the Survey Area supported numbers and diversity of wetland-dependent birds typical of fish pond areas. The WRA continues to attract wetland dependent fauna and serves as a buffer between the residential portion and the fishponds in the north.

5 Landscape and Visual

5.1 Site Inspections

The EM&A programme for Landscape and Visual impact due to the construction commenced in June 2010 and continued during the reporting period. Site inspections on Landscape and Visual impact were carried out on 14 and 29 August 2014 to confirm the implementation of mitigation measures at construction stage.

5.2 Construction Phase Audit Summary

The audit was undertaken with references to the specific checklists provided in Tables 2.13 – 2.15 and audit results are summarized below in Table 5.1. Representative photos showing the implementation of mitigation measures are presented in Appendix M.

Table 5.1: Construction and Operation Phase Audit Summary

Area of Works

Items to be Monitored

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. (Appendix M Photo 1 – Table 2.14 CM2 refers)

No construction works were observed to have exceeded the site boundaries. 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 retained within the site along the northeast boundary, beside wetland restoration area, have been identified and protected by temporary protective fencing.

Streams

The works site is partly encircled by a berm / perimeter channel 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 ponds have been provided to enable primary treatment before discharge to mains drains.

Clearance of existing vegetation

Site clearance was completed prior to the commencement of construction.

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 soil material which had been excavated and stockpiled from the original site, has now been re-used within the landscape works.

Dust suppression measures are active along all 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 screen fence between the future residential sites and the constructed wetland restoration areas is complete. Fence has been painted green to match with the surrounding vegetated environment. (Appendix M Photo 1 – Table 2.14 CM2 refers)

Noise Barrier

Noise barriers have been installed along the southern and western boundaries of the site in accordance with the contract requirements. Their 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. (Appendix M Photo 4 – Table 2.14 CM6 refers)

Night-time lighting

No night-time works were reported to have been carried out during the monitoring period

Landscape and wetland treatments generally

Continuous belt of screen planting along the southern and western boundaries of the site has been completed. The formation, soiling and water control structures of the wetland restoration area have been completed. (Appendix M Photo 3 – Table 2.14 CM6 refers)

The wetland areas are being established, with the ponds are being seasonally filled with rain water. Planting of areas around the WRA cells is complete. No construction was carried out at the wetland restoration area after 15 November 2010. (Appendix M Photo 2 – Table 2.14 CM2 refers)

Soiling, etc.

The soiling for the advance planting strip has been completed. The soil placement and grading for each of the wetland restoration areas has been completed.

Plant supply

The plant material used in the Advance Planting Strip and in the WRA are all commonly available species and came from commercial sources.

Transplanted reeds (Phragmites australis) at the wetland habitat came from the temporary holding nursery onsite.

Planting

The total number of trees that will reach a minimum of 10m in the advance planting strip meets the contract requirements. The tree species are all from the approved list. This planting should achieve the required screening effect within the required time period. (Appendix M Photo 3 – Table 2.14 CM6 refers)

Some of the trees that were identified as dead in previous month or having defects (i.e. extensive bark damage, cavities, fungal growths, etc.) still need to be replaced with new specimens. Some of the recently planted trees are still in poor condition, but are showing small signs of graduate improvement

Seedling trees and shrubs, have been established at the margins of the wetland cells. Some additional fill-in planting has been undertaken.

Establishment Works

The advance planting, the compensatory planting and transplanted trees are generally being maintained by the landscape sub-contractor in accordance with the specification to ensure that the contract requirements are met, although treatment of damaged / defective trees needs urgent attention.

Some of the trees that were identified as dead in previous month still need to be replaced with new specimens. Trees with significant defects (i.e. extensive bark damage, cavities, fungal growths, etc.) need to be replaced with new specimens.

Most overhanging trees from adjacent property that were affecting the strip planting have been pruned back.

Many trees are growing (and have become dependent for support) on the noise barrier frame, and are being deformed and damaged. Trees should either be physically separated from the structure, or the structure modified to avoid impacting on trees.

Pruning of tall shrubs (e.g. Ligustrum sinensis) needs to be undertaken regularly.

Removal of extensive growth of weeds and invasive climbers in the space behind screen noise barrier needs to be undertaken on a monthly basis as they may be inhibiting the advance planting.

Phragmites australis reeds are now occupying at least 80% of the reed bed areas within the WRC (as per design), but have also spread to the non-reed bed areas and are out-competing the intended planting. Management of this vegetation is required if the intended planting design is to be achieved.

Regular horticultural maintenance (grass cutting, weeding, watering etc.) in the shrubs and tree seedling areas around the WRA cells is being undertaken. A comprehensive tree survey has just been undertaken by the new landscape contractor.

The growth of shrubs / seedlings on the north side of WRA1 remains fair.

6 Environmental Site Inspection and Audit

6.1 Site Inspection

The ET had carried out construction phase weekly site inspections on 5, 12, 19 and 26 August 2014. All observations have been recorded in the site inspection checklist and passed to the Contractor together with the appropriate recommended mitigation measures where necessary. The key observations from site inspections and associated recommendations are summarized in Table 6.1.

6.4 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 L. In particular, the following mitigation measures were brought to attention during the site audits:

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;

· During the dry season, sufficient water spraying should be provided at haul road to reduce dust emission; and

· Ensure proper functioning of the wheel wash facility.

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

· Effluent should be discharged in accordance with the discharge licence conditions;

· Soil contaminated with chemicals/oils should be removed from site and the voids should be created filled with suitable materials; and

· Silt and debris should be removed from the temporary drainage channel regularly.

Waste Management

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

· 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; and

· Oil stains on soil should be cleared by disposal of contaminated soil.

7.2 Record on Environmental Complaints received

No environmental complaint was received during the reporting month.

7.3 Record on Notifications of Summons and Successful Prosecution

No notifications of summons or successful prosecution were received the reporting month.

7.4 Review of Reasons for and Implications of Non-compliance, Complaints, Summons and Prosecutions

Non-compliance

Investigations have been carried out to identify the causes of water quality exceedance.

Complaints, Summons and Prosecutions

Not applicable for this reporting month.

7.5 Follow-up Actions Taken

Non-compliance

As non-compliances have been recorded, the Event and Action Plan has been followed. Although it is considered that the exceedances were not related to the Project, the Contractor was reminded to implement the water quality mitigation measures in accordance with the recommendation stated in Section 5.6.1 – 5.6.4 of the EIA Report as far as practicable and regular spot check would be conducted on the nearby discharge by Contractor and inform ET for investigation.

To cater for the site runoff in wet season, the Contractor has further enhanced the water quality mitigation measures by erecting several segments of rock bunds and installing a barrier at the discharge outlet to desilt and divert site runoff to sedimentation tanks and wastewater treatment facilities (Aquased), which will ensure all site runoff is treated to satisfactory quality before discharging into the northern ditches.

7.6 Cumulative Statistics for Complaints, Notifications of Summons and Successful Prosecutions

Cumulative statistics for complaints, notifications of summons and successful prosecutions for the Project account for period starting from the date of commencement of construction (i.e. 12 May 2010) to the end of the reporting month and are summarized in the Table 7.2 below.

8.1 Site Preparatory Works and Construction Works for the Coming Month

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

¡ Site formation

¡ Foundation work

¡ Pond drainage management (to lower the water level and remove unwanted species in the pond)

8.2 Key Issues for the Coming Months

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

¡ Generation of dust from activities on-site during dry weather conditions;

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

¡ Generation and treatment of site surface runoffs and wastewater from activities on-site and during wet weather conditions;

¡ 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 and to the drainage.

8.3 Monitoring Schedule for the Coming Month

The environmental site inspection and environmental monitoring will be continued in the coming month. Impact monitoring for air, noise, water quality, ecology and landscape and visual in accordance with the approved EM&A Manual has commenced since 12 May 2010. The tentative monitoring schedule for September 2014 is shown in the Table 8.1.

Table 8.1: Tentative Environmental Monitoring and Audit Schedule for September 2014

8.4 Conclusions and Recommendations

8.4.1 Conclusions

The EM&A programme as recommended in the EM&A manual has been undertaken in the reporting month since 12 May 2010.

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 L_eq) and water quality parameters (such as pH, DO, turbidity and SS) under monitoring have been checked against established Action and Limit levels.

There was no breach of Action or Limit levels for Air Quality (1-hr TSP and 24-hr TSP) and Noise level (as Leq) in the reporting month.

During August 2014, two exceedances of DO were observed at MP3. No exceedance was observed at MP4, MP5 and MP6.

8.4.2 Recommendations

With considerations on the construction activities and environment, the following recommendations were provided:

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;

· During the dry season, sufficient water spraying should be provided at haul road to reduce dust emission; and

· Ensure proper functioning of the wheel wash facility.

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

· Effluent should be discharged in accordance with the discharge licence conditions;

· Soil contaminated with chemicals/oils should be removed from site and the voids should be created filled with suitable materials; and

· Silt and debris should be removed from the temporary drainage channel regularly.

Waste Management

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

· 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; and

· Oil stains on soil should be cleared by disposal of contaminated soil.
