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 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

Follow up actions have been undertaking by the Contractor to resolve the deficiencies The details of complaint are listed below:-

Investigation Result for the Verbal Complaint received by the Contractor on 4 January 2016

9.1.3 On 4 January 2016, a land user of the farm located at junction of Ng Chow Road and Wo Keng Shan Road notified the Contractor of C6 (CCKJV) that muddy water was observed in the his land area. It was suspected that the muddy water was discharged from the construction site of C6.

9.1.4 According to the information provided by the CCKJV, pump pipe burst from the bored piling work at Bridge B was occurred at around 6pm on 4 January 2015. The muddy water from the burst pump pipe was accidentally leaked to the adjacent river channel and the concerned farm which next to the bored piling area. Immediate action has undertaken by CCKJV as follows:-

(a) The muddy water in the affected channel was trapped by the Contractor to stop further spreading

(b) The muddy water in the affected channel was pumped to the wastewater treatment facilities for proper treatment and then recirculated for the bored piling work

9.1.5 On 5 January 2016 morning, representatives of CCKJV, AECOM and the land user were carried out joint inspection at the affected farm to investigate the source of muddy water and negotiate the remediate works. Under their investigation, it was considered that the muddy water in the farm was come from the leakage of burst pump pipe from bored piling work at Bridge B. Some of the muddy water on the affected farm has been cleaned up by the workers of CCKJV. However, the land user of the farm expressed that they will carry out intense remediate work on the farm as the cumulated mud may affect the crops on his farm.

9.1.6 A joint site inspection by the RE, IEC, Contractor and ET was carried out on 7 January 2016 at Bridge B and the adjacent channel follow up the status of the complaint and remediate action. During site inspection, it was observed that the affected channel was kept clear of muddy water and it is believe that the Contractor has completed the clearing works. To avoid reoccurrence of similar incident, the Contractor has constructed site hoarding for surrounding the site area and it was completed on 21 January 2016.

The soil/ muddy water were cumulated at the road and this situation has been observed for a long period of time. It was suspected that the wheel washing facilities of the construction site was not in proper function and follow up action is required.

9.1.8 A joint site inspection among EPD/AECOM/CCKJV/DHK was conducted on 21 January 2016 morning for the complaint investigation. It was noted that the complaint location is the site exit of North Portal adjacent to Sha Tau Kok Road. The concerned site exit was previously maintained by Contractor of Contractor 2 (DHK) provided with automatic wheel washing facility. Since the concerned area had been handed over to Contractor of Contract 6 (CCKJV), DHK has relocated the wheel washing facility within the boundary of Contract 2. The current exit of North Portal is being shared by Contract 2 and Contract 6 but maintained by CCKJV.

9.1.9 Joint site inspection among RE, IEC, CCKJV and ET was conducted on 21 January 2016 afternoon at the complaint location for investigation. It was observed that muddy water was cumulated at the roadside of Sha Tau Kok Road. Manual wheel washing was provided before the site exit and there was cut-off ditch to intercept any storm water or residual water from manual wheel washing, however, the ditch was damaged due to frequent passage of truck and the muddy water generated by manual wheel washing was getting into the adjacent Sha Tau Kok Road.

9.1.10 CCKJV was advised to immediately provide protection for the road gully outside the site exit to avoid muddy water directly getting into the communal drainage. Moreover, the Contractor should repair the damage road surface and reinstate the cut-off ditch in proper function. The remedial works were completed on 5 February 2016 afternoon as following:-

(a) A new cut-off ditch was constructed in order to divert the wastewater generated from wheel washing activity to the sump pit. Manual wheel washing would only conduct behind the new cut-off ditch to ensure all wastewater from wheel washing being intercepted.

(b) The damaged cut-off ditch was repaired in order to prevent wastewater being overflow to public road.

(d) Sedimentation tank and sand bag bund was installed and removal of silt in the sedimentation tank would be carried out once per week.

9.1.11 During site inspection on 12 February 2016, it was observed that the remedial works by CCKJV was properly in place and no cumulated muddy water was observed at the concerned site exit. However, CCKJV was advised to closely monitor the condition of the site exit and further improve the wheel washing facilities if necessary.

11.1.1 This is the 30^th monthly EM&A report presenting the monitoring results and inspection findings for the Reporting Period from 1 to 31 January 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 No 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. No NOEs or the associated corrective actions were therefore issued.

11.1.4 For water quality monitoring, a total of twenty-three (23) Limit/Action Levels exceedances were recorded, namely one (1) AL and twelve (12) LL exceedance of turbidity and one (1) AL and nine (9) LL exceedance of Suspended Solids for the Project. 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. However, a warning letter from EPD was issued to Contract 6 on 1 February 2016 regarding Non Compliance (NC) with APCO for the non-covered dump trucks travelling to Fill Bank at TM Area 38 on 14 and 18 January 2016 respectively. The Contractor has explained to the EPD that all dump trucks under the Contract were well covered before leaving the site, however, some drivers of the dump trucks immediately opened the cover when they just get into Fill Bank at TM Area 38 and captured by the CCTV. A briefing and warning letter has given to the relevant drivers to prevent reoccurrence of similar case.

11.1.6 In this Reporting Period, one (1) verbal complaint received by the Contractor and two (2) documented environmental complaints regarding wastewater / muddy water related to Contracts 6 were received and lodged by EPD on 14 and 20 January 2016 respectively.
