3.6 Monitoring Methodology

1-hour TSP Monitoring

3.6.1 The 1-hour TSP monitor was a brand named “Sibata LD-3B Laser Dust monitor Particle Mass Profiler & Counter” which is a portable, battery-operated laser photometer. The 1-hour TSP meter provides a real time 1-hour TSP measurement based on 90^o light scattering. The 1-hour TSP monitor consists of the following:

(a.) A pump to draw sample aerosol through the optic chamber where TSP is measured;

(b.) A sheath air system to isolate the aerosol in the chamber to keep the optics clean for maximum reliability; and

(c.) A built-in data logger compatible with Windows based program to facilitate data collection, analysis and reporting.

3.6.2 The 1-hour TSP meter is used within the valid period as follow manufacturer’s Operation and Service Manual.

24-hour TSP Monitoring

3.6.3 The equipment used for 24-hour TSP measurement is Tisch Environmental, Inc. Model TE-5170 TSP high volume air sampling system, which complied with EPA Code of Federal Regulation, Appendix B to Part 50. The High Volume Air Sampler (HVS) consists of the following:

(a.) An anodized aluminum shelter;

(b.) A 8”x10” stainless steel filter holder;

(c.) A blower motor assembly;

(d.) A continuous flow/pressure recorder;

(e.) A motor speed-voltage control/elapsed time indicator;

(f.) A 7-day mechanical timer, and

(g.) A power supply of 220v/50 Hz

3.6.4 The HVS is operated and calibrated on a regular basis in accordance with the manufacturer’s instruction using Tisch Calibration Kit Model TE-5025A. Calibration would carry out in two month interval.

3.6.5 24-hour TSP is collected by the ET on filters of HVS and quantified by a local HOKLAS accredited laboratory, ALS Technichem (HK) Pty Ltd (ALS), upon receipt of the samples. The ET keep all the sampled 24-hour TSP filters in normal air conditioned room conditions, i.e. 70% RH (Relative Humidity) and 25^oC, for six months prior to disposal.

Noise Monitoring

3.6.6 Noise measurements were taken in terms of the A-weighted equivalent sound pressure level (L_eq) measured in decibels dB(A). Supplementary statistical results (L₁₀ and L₉₀) were also obtained for reference.

3.6.7 During the monitoring, all noise measurements would be performed with the meter set to FAST response and on the A-weighted equivalent continuous sound pressure level(L_eq). Leq_(30min) in six consecutive Leq_(5min) measurements will use as the monitoring parameter for the time period between 0700-1900 hours on weekdays; and also Leq_(15min) in three consecutive Leq_(5min)measurements would be used as monitoring parameter for other time periods (e.g. during restricted hours), if necessary.

3.6.8 Prior of noise measurement, the accuracy of the sound level meter is checked using an acoustic calibrator generating a known sound pressure level at a known frequency. The checking is performed before and after the noise measurement.

Water Quality

3.6.9 Water quality monitoring is conducted at the designated or alternative locations. The sampling procedures with the in-situ monitoring are presented as below:

Sampling Procedure

3.6.10 A Digital Global Positioning System (GPS) is used to identify the designated monitoring stations prior to water sampling. A portable, battery-operated echo sounder or tape measurement is used for the determination of water depth at each station. At each station, water sample would be collected from 0.1m below water surface or the water surface to prevent the river bed sediment for stirring.

3.6.11 The sample container will be rinsed with a portion of the water sample. The water sample then will be transferred to the high-density polythene bottles as provided by the laboratory, labeled with a unique sample number and sealed with a screw cap.

3.6.12 Before sampling, general information such as the date and time of sampling, weather condition as well as the personnel responsible for the monitoring would be recorded on the field data sheet.

3.6.13 A ‘Willow’ 33-liter plastic cool box packed with ice will be used to preserve the water samples prior to arrival at the laboratory for chemical determination. The water temperature of the cool box is maintained at a temperature as close to 4⁰C as possible without being frozen. Samples collected are delivered to the laboratory upon collection.

In-situ Measurement

3.6.14 YSI PRO20 Handheld Dissolved Oxygen Instrument or YSI Professional DSS is used for water in-situ measures, which automates the measurements and data logging of temperature, dissolved oxygen and dissolved oxygen saturation.

3.6.15 A portable AZ Model 8685 pH pen-style meter or YSI Professional DSS is used for in-situ pH measurement. The pH meter is capable of measuring pH in the range of 0 – 14 and readable to 0.1.

3.6.16 A portable Hach 2100Q Turbidimeter or YSI Professional DSS is used for in-situ turbidity measurement. The turbidity meter is capable of measuring turbidity in the range of 0 – 1000 NTU.

3.6.17 All in-situ measurement equipment are calibrated by HOKLAS accredited laboratory of three month interval.

Laboratory Analysis

3.6.18 All water samples analyzed Suspended Solids (SS) will be carried out by a local HOKLAS-accredited testing laboratory (ALS Technichem (HK) Pty Ltd HOKLAS registration no. 66). SS determination using APHA Standard Methods 2540D as specified in the EM&A Manual will start within 48 hours of water sample receipt.

3.7 Equipment Calibration

3.7.1 Calibration of the HVS is performed upon installation and thereafter at bimonthly intervals in accordance with the manufacturer’s instruction using the certified standard calibrator (TISCH Model TE-5025A). Moreover, the Calibration Kit would be calibrated annually. The calibration data are properly documented and the records are maintained by ET for future reference.

3.7.2 The 1-hour TSP meter was calibrated by the supplier prior to purchase. Zero response of the equipment would be checked before and after each monitoring event. Annually calibration with the High Volume Sampler (HVS) in same condition would be undertaken by the Laboratory.

3.7.3 The sound level meter and calibrator are calibrated and certified by a laboratory accredited under HOKLAS or any other international accreditation scheme at yearly basis.

3.7.4 All water quality monitoring equipment would be calibrated by HOKLAS accredited laboratory of three month intervals.

3.7.5 The calibration certificates of all monitoring equipment used for the impact monitoring program in the Reporting Period and the HOKLAS accredited certificate of laboratory are attached in Appendix F.

3.8 Derivation of Action/Limit (A/L) Levels

5.1.3 The noise monitoring schedule is presented in Appendix H and the monitoring results are summarized in the following sub-sections.

5.2 Noise Monitoring Results in Reporting Month

5.2.1 In the Reporting Period, a total of 45 event noise measurements were carried out at the designated locations. The sound level meter was set in 1m from the exterior of the building façade including noise monitoring locations NM1, NM3, NM4, NM5, NM6, NM7, NM8 and NM9. Therefore, no façade correction (+3 dB(A)) is added according to acoustical principles and EPD guidelines. However, free-field status were performed at NM2a and NM10 and façade correction (+3 dB(A)) has added according to the requirement in this month. The noise monitoring results at the designated locations are summarized in Tables 5-1 and 5-2. The detailed noise monitoring data are presented in Appendix I and the relevant graphical plots are shown in Appendix J.

6.2.3 In this Reporting Period, a total of thirty-one (31) Limit Level (LL) exceedances and one (1) Action Level (AL) exceedance, namely fifteen (15) LL exceedances and one (1) AL exceedance of turbidity and sixteen (16) LL exceedances of Suspended Solids were recorded for the Project and they are summarized in Table 6-5.

6.2.4 NOE was issued to relevant parties upon confirmation of the monitoring result. The cause of exceedance is summarized in Table 6-6 accordance to investigation findings and the detailed investigation reports for the exceedances are attached in Appendix N.

Table 6-6 Summary of Water Quality Exceedance in the Reporting Period

Date of Exceedance	Location	Exceeded Parameter	Cause of Water Quality Exceedance
6^th June 2016	WM1 (C5, C6 and SS C505)	NTU & SS	According to the Daily Extract of Meteorological Observations from the Hong Kong Observatory, heavy rainfall was recorded on 6 June 2016. Water flow rate increased vigorously under the heavy rain and the sediment at the river bed was stirred up, resulting in turbid water. According to the field photos, accumulation of rubbish were observed at the bar screen of the box culvert near WM1 after heavy rainstorm on 6 June 2016. Water flow near WM1 was therefore retarded and turbid water was cumulated at WM1. Also, water level at the box culvert increased to a high level due to the combined effect of heavy rain and accumulation of rubbish, overflow of the Kong Yiu River occurred. Hence, it is considered that the exceedance on 6 June 2016 was due to the heavy rain and accumulation of rubbish at the bar screen of the box culvert near WM1, and unlikely due to the construction activities of the Contract.
4^th,6^th, 7^th, 8^th, 13^th, 14^th, 15^th 16^th, 17^th, 18^th, 20^th, 21^th, 30^th June 2016	WM2A (C6)	NTU &SS	Exceedances on 4^th, 6^th, 7^th, 8^th June 2016 During joint site inspection with RE, IEC, ET and Contractor on 2 June 2016, it was observed that unknown source of turbid water was seeping out from the river bed at upstream of WM2A continuously, turning the water in the river turbid. From the photo taken by the Contractor on 4 June 2016, it was observed that turbid water was seeping out from the river bed at upstream of WM2A continuously. Thus, it is considered that the exceedance on 4 June was likely due to the unknown source of turbid water. According to the Daily Extract of Meteorological Observations from the Hong Kong Observatory, intense rainfall (100-150 mm) was recorded at Ta Kwu Ling monitoring station on 6 June 2016. Under the intense rain, water flow rate increased vigorously and the sediment at the river bed was stirred up at WM2A, resulting in turbid water. As the river bed at WM2A-C was mostly small rocks, the stirred up of sediment at WM2A-C was limited. The turbid water recorded at WM2A-C may due to runoff from upper stream or surrounding slopes. According to the Daily Extract of Meteorological Observations from the Hong Kong Observatory, heavy rainfall (10-20 mm) was recorded at Ta Kwu Ling monitoring station on 7 and 8 June 2016. Water flow rate increased and the stirred up sediment could not settle down in a short period of time after intense raining on 6 June 2016. The river bed at WM2A was cumulated with thick silt and sediment, while the river bed at WM2A-C was mostly small rocks. Hence, sediment stirred up more vigorous in WM2A while the stirred up of sediment at WM2A-C was limited. It is considered that the exceedances on 6, 7 and 8 June at WM2A were related to the heavy rainfall. Exceedance on 30^th June 2016 During weekly joint site inspection with RE, IEC, ET and Contractor(CCKJV) on 30 June 2016, no discharge and surface runoff was observed from the site. As water mitigation measures, wastewater treatment facilities including one AquaSed and three series of sedimentation tank have been installed for piling work and most of the time the wastewater was recirculated. However, it was observed that unknown source of turbid water was seeping out from the river bed. Hence, it is considered that the exceedance on 30 June 2016 was due to the above event. Exceedance on 13^th, 14^th, 15^th 16^th, 17^th, 18^th, 20^th, 21^th June During joint site inspection with RE, IEC, ET and Contractor (CCKJV) on 16 June 2016, no surface runoff was observed from the site into the river. As advised by the Contractor, the source of turbid water recorded at WM2A was identified. Due to continual heavy loading, uneven ground and cracks on the haul road were formed. As dust suppression measures, a series of sprinklers was installed along the haul road for continuous spraying and the excessive water was cumulated on uneven ground/ cracks. When vehicles passed the puddles, muddy water trapped on the uneven ground/ cracks was spilled from the road into a channel connecting to Ping Yuen River. To resolve the deficiency, the Contractor has filled the uneven ground and reduce the frequency of water spraying on that area. Also, the haul road was levelled up to avoid muddy runoff. The situation was found improved during site inspection on 7 July 2016. There was no exceedance recorded in the subsequent monitoring days on 22, 23 June 2016. Hence, it is considered that the rectification measures carried out by the Contractor were effective in preventing further exceedances.
6^th June 2016	WM2B (C6)	NTU &SS	According to the Daily Extract of Meteorological Observations from the Hong Kong Observatory, heavy rainfall was recorded on 6 June 2016. The flow rate of the river increased vigorously, sediment and cumulated silt at the river bed was stirred up during rain, resulting in turbid water in river channel. Apart from the disturbance of cumulated silt at the river bed during rain, it was observed that trails of muddy runoff from the public road surface into the existing channel under the rain. Thus, it is considered that the exceedance on 6 June 2016 is due to the heavy rainfall.
6^th June 2016	WM4 (C2 and C3)	NTU &SS	According to the Daily Extract of Meteorological Observations from the Hong Kong Observatory, heavy rainfall was recorded on 6 June 2016. Water flow rate increased vigorously under the heavy rain and the sediment at the river bed was stirred up, resulting in turbid water. It is considered that the exceedances were due to the heavy rainfall and unlikely related to the construction activities under the Contracts.

Two (2) documented environmental complaint received in April 2016 and Three (3) documented environmental complaints received in May 2016 were completed investigation. The investigation reports were reviewed by IEC. The detail of the complaints and the investigation results are presented below.

Investigation Result for the Documented Complaint received by 1823 on 28 April 2016

9.1.2 A complaint was received on 28 April 2016 regarding suspected muddy water discharged from the construction site, affecting the growth of crops and condition of soil in farmland at junction of Wo Keng Shan Road and Ng Chow Road. The complainant also claimed that the gravestone was disappeared due to the construction activities in the above location.

9.1.3 As the exact location of the disappeared gravestone cannot be provided by the complainant, investigation regarding to it cannot be conducted.

9.1.4 According to Contractor’s record (CCKJV), starting from the project’s commencement, there is only one report of accidental leakage of muddy water from the site into the nearby farmland on 4 January 2016. Since after that, contractor and ET do not receive any record or complaint regarding to the discharge of muddy water to the nearby farms.

9.1.5 During weekly joint site inspections with RE, IEC, ET and Contractor, no leakage of muddy water to the nearby farms was observed.

9.1.6 As advised by the Contractor (CCKJV), the construction activities in the above location is mainly bored piling work. This construction activity unlikely generates any chemicals that contaminate the soil and adversely affect the growth of crops.

9.1.7 To collect runoff due to the rain, the Contractor has provided mitigation measures such as site hoardings, concrete blocks, sandbags and temporary drainage. Also, it is advised that runoff due to the rain unlikely contains any chemicals that contaminate the soil and adversely affect the growth of crops.

9.1.8 On 26 May 2016, a joint site inspection was carried out with RE, IEC, ET and Contractor, the findings during the site inspection are summarized below:

(a) No leakage of soil or muddy water was observed from the site to the concerned farm.

(b) Site hoardings, concrete blocks and sandbags barriers have been constructed along the boundary of the farm.

(c) Temporary drainage was constructed and regularly maintained. Runoff is collected and diverted to treat in wastewater treatment facilities including the sedimentation tank and AquaSed. (As advised by the Contractor, in order to further enhance the performance of collecting runoff, water pump was provided to pump runoff in the temporary drainage to the wastewater treatment facilities)

9.1.9 Based on the site observations and the work activity of the site, the complaint regarding to discharge of muddy water from the construction site, affecting the growth of crops and the condition of soil is not evidenced. Nevertheless, the Contractor (CCKJV) is reminded to follow the mitigation measures as recommended in the EM&A Manual. The ET will continue inspect the environmental performance of the construction site and ensure all activities comply with the relevant environmental contractual requirement.

Investigation Result for the Documented Complaint received by 1823 on 21 April 2016

9.1.10 A complaint was received from 1823 on 21 April 2016 and passed to CEDD and EPD. There are two concerns. Firstly, it is suspected that dump trucks were not washed in wheel washing facilities before leaving the site and the site had not carried out water spraying. Hence, these suspected concerns lead to dust nuisance to the nearby farmlands. Secondly, it is suspected that the Contractor discharged wastewater directly into the storm drain and Ng Tung River, affecting the residents and farmers of Tai Tong Wu.

9.1.11 A joint inspection was carried out by the Contractor, CEDD and RE on 21 April 2016. The inspected area included the wastewater treatment facilities (AquaSed SH-15) of C6 (CCKJV). CEDD has not given any adverse comments.

9.1.12 Dust

As advised by Contractor C6(CCKJV), they have carried out dust suppression measures to minimize construction dust impact. For instance,

(a) Use of regular watering to reduce dust emissions from the construction sites, particularly during dry weather.

(b) Establishment and use of wheel washing facilities at the exit points of the site.

During weekly joint site inspection with RE, IEC, ET and Contractor on 7 April 2016, it was observed that wheel washing facilities was provided at vehicle exit point. Also, the exit was hard paved. The cleanliness condition of the site exit connecting to Sha Tau Kok Road was satisfactory.

9.1.13 As reported by C6, they have carried out regular watering to reduce dust impact. Besides, tarpaulin covering was provided on exposed slopes to minimize dust impact.

9.1.14 According to our air quality monitoring records from January to April 2016, no limit level exceedance was recorded on 1-hour and 24-hour Total Suspended Particulates (TSP) levels at air monitoring station AM7b, which is the nearest one to the complaint area.

9.1.15 Based on the observations from the site inspections and monitoring data, it is considered that the complaint regarding to dust is not evidenced.

9.1.16 Wastewater

As advised by Contractor of C6(CCKJV), in April 2016, all wastewater from that site area was stored in temporary pit and diverted to treat in wastewater treatment facilities including sedimentation tank and AquaSed. After that, all treated effluent was diverted to the drainage hole and then the drainage outlet for discharge.

9.1.17 During site inspection with Contractor(C6) on 23 May 2016, it was observed that the Contractor (C6) has provided AquaSed for wastewater treatment. From the photo taken, the effluent was visually clear. (Photo 8) Runoff from wheel washing is diverted to the temporary pit and then to the AquaSed. The treated effluent is used for wheel washing or diverted to the drainage outlet for discharge. Also, all storm drains were blocked. No discharge of wastewater or runoff into the storm drains and directly into Ng Tung River could be observed.

9.1.18 According to the monitoring data in April 2016, out of thirteen samplings in WM-3, four exceedances of turbidity at WM-3 was recorded and investigated. Investigation reports concluded that none of the exceedances were due to the direct discharge of wastewater into the storm drains or Ng Tung River.

9.1.19 Based on the observations from site inspection and the result of monitoring data, the complaint regarding to the direct discharge of wastewater in storm drains and Ng Tung River is not evidenced.

9.1.20 The Contractor (C6) is reminded to follow the mitigation measures as recommended in the EM&A Manual. Mitigation measures such as increasing the frequency of watering if necessary, carrying out regular desilting of sedimentation tanks shall be maintained. ET will continue inspect the environmental performance of the construction site and ensure all activities comply with the relevant environmental contractual requirement.

Investigation Result for the Documented Complaints received by 1823 on 28 May 2016

(a) During the investigation, the cleanliness condition of the Lin Ma Hang Road at the Portion of BCP area was satisfactory. No muddy trails or loosen mud was found on Lin Ma Hang Road and the site exit of SS C505.

(b) Automatic wheel washing facilities were provided at the site exit and labour was also provided at the site exit to maintain cleanliness.

(c) It was concluded that construction works are located far from the complaint’s location and the condition of site exit of SS C505 and the adjacent public road were considered as satisfactory.

9.1.53 As advised by the Contractors, public road cleaning was provided on Lin Ma Hang Road by the Contractor of Contract 5 and Contract 6.

9.1.54 As informed by C6, muddy water leakage via the bored pile area entering the Lin Ma Hang Road was accidentally occurred at 11 am on 10^th June 2016. Immediate corrective actions had promptly taken to stop the leakage and the muddy water on the public road was also cleaned up by 12:15 noon.

9.1.55 As reported by C5, a private trailer driving through a muddy ground to Lin Ma Hang Road was recorded in the afternoon on 10^th June 2016. Afterward muddy trails were found on road where is within the complaint’s location in Lin Ma Hang Road.

9.1.56 According to the Hong Kong Observatory record, about 20mm ~ 30mm rainfall was recorded in North District at 12 noon to 2 p.m. on 10 June 2016. As one of the considerations, the rainwater could cumulate in the uneven ground surface on Lin Ma Hang Road and cause puddle.

9.1.57 In conclusion, firstly immediate corrective actions for the incident of leakage to stop the leakage and to clean up muddy water on the road were taken by C6 within an hour. Furthermore, the location of leakage was not within the complaint’s area. Secondly, rainwater accumulated in the uneven ground surface in Lin Ma Hang Road could possibly happened during and after the rainfall. Thirdly, private trailer causing muddy trails within the complaint’s area was recorded and the puddle could lead to the occurrence of muddy water. Finally, based on our observations from the investigation on 14^th June 2016, it is considered that the mud on Lin Ma Hang Road is unlikely due to the Contract 5 (SRJV), Contract 6 (CCKJV), Contract 7 (KRSJV) and SS C505 (Leighton). Nevertheless, ET will continue to inspect the cleanliness of site exits and adjacent roads.

9.1.58 In view of the incident of leakage by C6, the Contractor of C6 is recommended to improve the preventive measures of surface run-off and improve the condition of uneven ground surface in Lin Ma Hang Road, such as 1.) Improve cut-off drain at site exits for the water diversion and prevention of surface run-off. 2.) Enhance the preventive measures such as sandbag bund, earth bund and U-channel at construction activities area. 3.) Improve the condition of uneven ground surface to minimize puddle in Lin Ma Hand Road.

Investigation Result for the Documented Complaints received by 1823 on 20 June 2016

9.1.59 A complaint received from 1823 on 20 June 2016 regarding noise nuisance from Lain Tang Construction work. After identifying the date, time as well as the exact location with the complainant, the complainant advised that the concerned construction work was not carried out by CEDD’s Contractors. The complainant complained that piling works carried out by (SSC 505) Leighton subcontractor Kwan Shing at BCP site recently generated high noise level. Also, during the piling works, the complainant queried why no noise abatement measures such as fabric cover being available. The complaint was transferred to ArchSD on 8 July 2016. This complaint is still under investigation and the result will be presented in the next monthly report.

Investigation Result for the Documented Complaints received by ICC on 20 June 2016

9.1.60 A complaint was received from ICC, regarding uneven ground and muddy water found on Lin Ma Hang Road.

9.1.61 During weekly joint site inspection by RE, IEC, ET and Contractor (CCKJV) on 30 June 2016, uneven ground was found near the site exit of piling portion of Contract 6 on Lin Ma Hang Road. It was observed that muddy water was cumulated in the puddles created from the uneven ground after road cleaning by water truck and rainfall.

9.1.62 Since Lin Ma Hang Road is a public road and frequent used by heavy vehicles, it is believed that the uneven ground was due to over usage and not created by construction of Contract 6.

9.1.63 Regarding to the muddy water issue, there were three site exits located on Lin Ma Hang Road and the condition of the site exits were inspected during regular site inspection. Our observations are summarized in below.

9.1.64 (a) The site exit (SA22) was provided with wheel washing facility and the exit road was hard paved in concrete. No muddy water getting into Lin Ma Hang Road was observed.

9.1.65 (b) The site exit of piling portion was provided with high pressure water jet and labour for wheel washing. Also, cut off drain was provided at site exit for collecting water from vehicles’ washing. No muddy water getting into Lin Ma Hang Road was observed.

9.1.66 (c) The site exit of Bridge Y was provided with high pressure water jet and labour for wheel washing. No muddy water getting into Lin Ma Hang Road was observed.

9.1.67 According to the findings during site inspection, the muddy water found on Lin Ma Hang Road was unlikely caused by the works of CCKJV. To address public concern, C6 has repaired the uneven ground by paving asphalt on 8 July 2016 to minimize the impact to the public. The ET will closely inspect the cleanliness of the Lin Ma Hang Road in forthcoming site inspections.

11 Conclusions and Recommendations

11.1 Conclusions

11.1.1 This is the 35^th monthly EM&A report presenting the monitoring results and inspection findings for the Reporting Period from 1 to 30 June 2016.

11.1.2 For air quality monitoring, no 1-hour and 24-hour TSP monitoring results triggered the Action or Limit Levels were recorded. No NOEs or the associated corrective actions were therefore issued.

11.1.3 One noise complaint (which is an Action Level exceedance) was received and no construction noise measurement results that exceeded the Limit Level were recorded in the Reporting Period. The associated investigation report was submitted to relevant parties. No NOEs or the associated corrective actions were issued.

11.1.4 For water quality monitoring, a total of thirty-two (32) Action/ Limit Levels (AL/LL) exceedances, namely fifteen (15) LL exceedances and one (1) AL exceedance of turbidity and sixteen (16) LL exceedances of Suspended Solids. The investigations for the cause of exceedances have been conducted by the ET and the associated investigation reports were submitted to relevant parties.

11.1.5 No environmental summons or successful prosecutions were recorded in the Reporting Period.

11.1.6 In this Reporting Period, a total three (3) documented environmental complaint were received in the reporting month regarding to water, dust and noise issue. Upon receipt of the complaints, RE, IEC and ET with the relevant Contractors has immediately undertaken investigation. In the Reporting Period, one complaint is under investigation, the investigation result will be presented in the coming monthly report.

11.1.7 During the Reporting Period, weekly joint site inspection by the RE, IEC, ET with the relevant Main-contractor were carried out for Contracts 2, 3, 5, 6, 7 and SS C505 in accordance with the EM&A Manual stipulation. No non-compliance observed during the site inspection.

11.2 Recommendations

11.2.1 As wet season has come, preventive measures for muddy water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma Wat Channel, Ping Yuen River or public area would be the key issue. The Contractors should paid special attention on water quality mitigation measures and fully implement according ISEMM of the EM&A Manual, in particular for working areas near Ma Wat Channel and Ping Yuen River. Moreover, all effluent discharge shall be ensure to fulfill Technical Memorandum of Effluent Discharged into Drainage and Sewerage Systems, inland and Coastal Waters criteria or discharge permits stipulation.

11.2.2 Construction noise would be a key environmental issue during construction work of the Project. Noise mitigation measures such as using quiet plants should be implemented in accordance with the EM&A requirement.

11.2.3 Since most of construction sites under the Project are located adjacent to villages, the Contractors should fully implement air quality mitigation measures to reduce construction dust emission.

11.2.4 Furthermore, daily cleaning and weekly tidiness shall be properly performed and maintained. In addition, mosquito control should be kept to prevent mosquito breeding on site.
