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; 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 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 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 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

3.8.1 The baseline results form the basis for determining the environmental acceptance criteria for the impact monitoring. According to the approved Environmental Monitoring and Audit Manual, the air quality, construction noise and water quality criteria were set up, namely Action and Limit levels are listed in Tables 3-8, 3-9 and 3-10.

5.2.2 As shown in Tables 5-1 and 5-2, the noise level measured at all designated monitoring locations were below 75dB(A). Moreover, no valid noise complaint (which triggered Action Level exceedance) was recorded in the Reporting Period.

5.3 Noise Monitoring Results (Restricted Hours)

5.3.1 In the Reporting Period, CNPs were granted by Contracts 2, 3, 6, 7 and SS C505 for use of Powered Mechanical Equipment (PME) during restricted hour. As confirmed by both Contractors with their works schedules, construction works would be conducted at Contract 2, 3, 6 and SS C505 during restricted hours with the granted CNP. Noise monitoring was therefore conducted at the relevant noise monitoring locations during respective restricted hour periods.

5.3.2 Based on the works schedule by the Contractor of Contracts 2, 3, 6, 7 and SS C505, the involved noise monitoring locations included NM4, NM5, NM7, NM8, NM9 and NM10 and the noise monitoring results are summarized in Tables 5-3 and 5-4.

5.3.3 According to the site records by the monitoring team, no construction noise from the construction was noted during the course of monitoring at all locations. On the other hand, traffic noise was dominated at NM8 and NM9 since the monitoring locations were closed to the train tracks and occasionally noise from vehicle and dogs barking were recorded at all stations. Therefore, it is considered that the measurement results were likely to be the background noise.

Investigation Result for the Documented Complaint by DSD on 3 January 2017 (Contract 2)

10.1.10 DSD conducted site inspection on 3 January 2017 at Kwan Tei River near Po Kak Tsai and suspected construction foul water was found in the branch of Kwan Tei River. Subsequent site inspection in Kwan Tei River was conducted by DSD and EPD on 6 and 10 January 2017 respectively for further investigation. According to DSD’s inspection report, a discharge of slurry had smothered Kwan Tei River and wiped out the Firefly trial site which was meant to be a showcase of river health and the return of diverse freshwater life in the region. On EPD’s inspection on 10 January 2017, it revealed that the open channel which received discharge from the construction site was accumulated with slurry. According to the inspection records from DSD and EPD, the source of foul water was suspected to be construction site of Mid-Vent under Contract 2.

10.1.11 Joint site inspection among the RE, IEC, Contractor of Contract 2 (DHK) and ET was carried out on 13 January 2017 in Mid-vent and Kwan Tei River for the complaint investigation. The observations during site inspection are summarized below.

(a) Wastewater treatment facility was implemented at construction site of Mid-vent. It comprises of 5 nos. of sedimentation tanks, 3 nos. of de-silting pit, a WetSep and an AquaSed. The treated water was stored in the recycle water silo and discharge would be made when the water silo is full.

(b) There was discharge made from the Mid-vent during the site inspection and it was observed that the quality of discharge was visually clear.

(c) In view of the current site condition, the majority of wastewater was generated from the tunnelling works. The wastewater generated in the tunnel was pumped to the wastewater treatment facility for proper treatment prior discharge at the approved discharge point.

(d) During the inspection carried out along Kwan Tei River, it was observed that the existing water flowing in the river channel was visually clear. However, part of the river and channel bed was cumulated with silt and sediment, suspecting caused by the emergency discharge from DHK. DHK agreed to clean up the relevant channel as appropriated.

10.1.12 According to the incident report by DHK, in the morning of 28 December 2016 (at around 10:15am), a staff at Mid-vent worksite observed flooding of the Adit and water was flowing rapidly into the Adit and he realized that the 6” pump in Desilting Tank 3 was not working. To avoid flooding inside the tunnel which may cause danger to the safety of the people working inside the Adit, the staff of DHK switched on the emergency pump without informing the senior management of the site. The emergency pump was activated for about 15 minutes till 10:30am when AECOM observed muddy water discharge and instructed DHK to stop such discharge. On 28 and 29 December 2016, DHK had started removing silt deposited in the surface channels as well as those sections along stream that were accessible.

10.1.13 On 5 January 2017, AECOM received a complaint from DSD about silt deposit along the stream leading to Kwan Tei River. On 6 and 7 January 2016, DHK has arranged by 9 suction truck trips to clean the upper section of the stream. DSD issued another e-mail and mentioned the firefly issue on 10 January 2017. In view of the sensitivity of the site, a cleaning proposal was prepared by DHK to determine the affected area to be cleaned and method for the cleaning works and the proposal was agreed by DSD on 16 January 2017. The cleansing works was commenced on 17 January 2017 and completed by 27 January 2017 according to the agreed proposal. (Photo 13 to 16) A joint site inspection with DSD was conducted on 3 February 2017. Further minor clean up was agreed with DSD and re-inspection was arranged on 8 February 2017. DSD had no further comment on the final inspection carried out on 8 February 2017.

10.1.14 To avoid recurrent, further actions to be carried out by DHK were mentioned in the incident report, such as installation of sand trap as requested by DSD and additional monitoring point as requested by EPD and management of emergency situation by DHK. It also stressed that apart from the remedial actions that have been implemented after the incident, DHK has strengthened the management of flooding situation on Site. Only Construction Manager or above are involved in the decision-making and on top of that Project Management, AECOM and CEDD must be report of such decision.

10.1.15 In our investigation, it is considered that the complaint was caused by the inadvertent and unintentional emergency discharge by DHK in their consideration of safety of the people working inside the Adit. To maintain the wastewater water system, DHK has already increased to the frequency of sludge removal of the wastewater treatment facility to 3-5 times daily to reduce the load of the water pump. In our response to the complaint, DHK was advised that replacement by spare water pump should be made immediately when any malfunction event is alerted. Moreover, additional measures for flood control such as additional retention tanks or flood gates were recommended. In case of any emergence discharge, DHK should immediately clean up the deposition at the downstream channel to avoid water contamination spreading further downstream.

10.1.16 As requested by EPD, AECOM has discussed with ET and IEC regarding the suggestion from EPD to provide an additional water quality monitoring station. Finally, ET will keep closely monitor the site condition and status of implemented mitigation measures by DHK in weekly site inspection.

Investigation Result for the Documented Complaint received by EPD on 25 January 2017 (Contract 2)

10.1.17 The complaint is under investigation under ET and it will be reported in next Reporting Period.

10.1.18 Upon receipt of the complaint, follow up action has been undertaken by both Contractor promptly to resolve the complaints and deficiencies. During the complaint investigation work, the Contractor was co-operated with the ET in providing all the necessary information and assistance for completion of the investigation. Investigation report for the complaints on 3 and 16 January 2017 has been submitted to all relevant parties for review.

12 Conclusions and Recommendations

12.1 Conclusions

12.1.1 This is the 42^nd monthly EM&A report presenting the monitoring results and inspection findings for the Reporting Period from 1 to 31 January 2017.

12.1.2 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.

12.1.3 In the Reporting Period, no construction noise measurement results that exceeded the Limit Level were recorded. Moreover, no valid noise complaint which triggered an Action Level exceedance was recorded.

12.1.4 For water quality monitoring, two (2) LL exceedances, namely one (1) LL exceedance of turbidity and one (1) LL exceedances of Suspended Solids were recorded at WM4. According to the investigation result, all exceedances were concluded as not related to the works under the Project.

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

12.1.6 In this Reporting Period, a total of three (3) documented environmental complaints were received which all regarding to water quality aspect, in which two (2) complaints were related to Contract 2 and the other one was related to both Contracts 2 and 6. Investigation reports for two of the complaints were completed and submitted to relevant parties and the other one is under investigation.

12.1.7 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, 6, 7 and SS C505 in accordance with the EM&A Manual stipulation. No non-compliance observed during the site inspection.

12.2 Recommendations

12.2.1 During dry season, special attention should be paid on the potential construction dust impact since most of the construction sites are adjacent to villages. The Contractor should fully implement the construction dust mitigation measures properly.

12.2.2 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 should be properly maintained. 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.

12.2.3 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.

12.2.4 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.
