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 90o 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 25oC, 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 (Leq) 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 were performed with the meter set to FAST response and on the A-weighted equivalent continuous sound pressure level (Leq).  Leq(30min) in six consecutive Leq(5min) measurements were used as the monitoring parameter for the time period between 0700-1900 hours on weekdays; and also Leq(15min) in three consecutive Leq(5min) measurements is 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 was performed before and after the noise measurement.

 

Water Quality

3.6.9        Water quality monitoring is conducted at the designated locations. The sampling produce 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 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    Instrument including YSI Professional Plus or YSI 6820/650MDS or YSI PRO20 Handheld Dissolved Oxygen Instrument or YSI 550A Multifunctional Meter 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.  Before each round of monitoring, the dissolved oxygen probe would be calibrated by the wet bulb method.

 

3.6.15    A portable AZ8685 pH pen-style meter or YSI Professional Plus or YSI 6820/650MDS is used for in-situ pH measurement.  The pH meter is capable of measuring pH in the range of 0 ¡V 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 ¡V 1000 NTU.  StablCal® Standards of known NTU are used for calibration of the instrument before and after measurement.

 

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 are analyzed with Suspended Solids (SS) as specified in the EM&A Manual by a local HOKLAS-accredited testing laboratory (ALS Technichem (HK) Pty Ltd HOKLAS registration no. 66).  SS analysis is determined by the laboratory upon receipt of the water samples using APHA Standard Methods 2540D (namely ALS Method EA-025 as accredited HOKLAS Scheme) started 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 is 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 presented in the relevant monthly EM&A reports.  

 

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.

        Excessive water was cumulated on uneven ground/ cracks due to continuous spraying by a series of sprinklers installed along the haul road.  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.  The exceedances were related to the Contract 6.

        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.

9.1              Status of Non-compliance Environmental Complaint, Summons and Prosecution

9.1.1        In the Reporting Period, no non-compliance, no summons and prosecution under the EM&A Programme was recorded and lodged for the Project.  However, a total eleven (11) documented environmental complaints.  The summary of complaint received in the Reporting Period is listed below.

 

Ÿ  3 May 2016 - EPD conducted an inspection on construction site of Contract 2 (DHK) North Portal.  EPD noted that water was bursting out from one of the wastewater treatment facilities and muddy water was discharging into a channel connecting another channel outside the site.  Also, it was observed that the open channel was accumulated with thick mud.  Remedial measures were undertaken by DHK immediately and no adverse water impact was observed at the open channel during follow up inspection by ET on 20 May 2016.  In our investigation, it was advised that the Contractor shall properly maintain all wastewater treatment facilities. Dragages is advised to remove silt in the stormwater tank regularly or increasing the frequency if necessary in order to prevent the reoccurrence of the same issue.  (Contract 2)

Ÿ  28 May 2016 - A complaint was received from 1823, regarding to the mud found on Sha Tau Kok Road -Wo Keng Shan was suspected from the construction site of Contract 2 and Contract 6.  Site inspection for complaint investigation was conducted by ET on 2 and 3 June 2016.  It was observed that the wheel washing facilities were installed at all site exits and conditions of site exits were satisfactory.  Since there were many other heavy vehicles using the Sha Tau Kok -Wo Keng Shan Road, it is considered that the mud on Sha Tau Kok -Wo Keng Shan Road is unlikely due to the Contracts.  (Contract 2 and Contract 6)

Ÿ  26 May 2016 - A complaint was received from CEDD on 26 May 2016, regarding noise nuisance from the construction site of Contract 2 (North Portal). Loi Tung Villagers complained that noise was made at midnight from the construction site. Also, early in the morning at 5, dump trucks were suspected to operate in the construction site, making noise thus affecting the daily lives of villagers.  The Contractor advised that the noise source may come from the dump trucks queuing outside the site on Sha Tau Kok Road early in the morning at around 5 to 6, waiting to enter the construction site at around 7 am on working days (not included on Sunday or public holidays). To address public concern, DHK has requested the dump trucks¡¦ drivers to arrive after 6:30am on working days (not included on Sunday or public holidays). In the ET¡¦s investigation, there was no non-compliance of construction noise permit conditions. DHK was reminded to fully follow the conditions under the construction noise permit. (Contract 2)

Ÿ  31 May 2016 - A complaint was received from 1823, regarding water spraying over dump trucks was suspected to be carried out outside site area.  The above action resulted in muddy water on Sha Tau Kok Road - Wo Hang and Sha Tau Kok Road - Ma Mei Ha, affecting other road users.  As advised by Contractor (DHK), vehicles were thoroughly washed in the wheel washing facilities within the site area.  As observed during ET¡¦s site inspections on 2 and 3 June 2016, no water spraying activities outside the work area could be observed. Therefore,  the complaint regarding water spraying to dump trucks outside the work area is not evidenced based on the site observations, the Contractor was reminded to fully implement the mitigation measures as specified in the implementation schedule of the EM&A manual. (Contract 2)

Ÿ  10 June 2016 - A complaint was received from 1823 regarding to the mud found on Lin Ma Hang Road was suspected from the construction site.  Considering the site areas located along Lin Ma Hang Road, four contracts which under the Project may involve in this complaint, are included Contract 5 (SRJV), Contract 6 (CCKJV), Contract 7 (KRSJV) and SS C505 (Leighton). Inspection for complaint investigation was carried out on 14 June 2016.  Generally, no adverse dust impact were observed for all Contracts and public road cleaning was provided on Lin Ma Hang Road by the Contractor of Contract 5 and Contract 6 continuously. It is considered that the complaint was not related to the Project. Contract 5, Contract 6, Contract 7 and SS C505)

Ÿ  20 June 2016 - A noise complaint was received via 1823 on 20 June 2016 from a villager residing in Tsung Yuen Ha Village.  The complainant said that the piling works carried out by Leighton subcontractor Kwan Shing (§¡«°) at BCP site recently generated high noise level.  Also, he queried why no noise abatement measures such as fabric cover being available.  Site inspection was carried out by the ET on 22 and 29 June 2016 as well as 6 July 2016 and no adverse findings about the piling work were observed.  Leighton has followed the conditions as stipulated in the CNP such as piling location and operation period 0930 hrs to 1130 hrs and 1400 hrs to 1700 hrs on all days except general holidays.  To minimize the noise nuisance to the public, a noise shield act as a moveable noise barrier was adopted on piling machine during hard driving.  In our conclusion, the piling works carried out by Leighton did not violate any NCO, EP and EM&A requirement. (Contract SS C505)

 

Ÿ  20 June 2016 - A complaint was received from ICC, regarding uneven ground and muddy water found on Lin Ma Hang Road. 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.  During weekly joint site inspection by RE, IEC, ET and Contractor (CCKJV) on 30 June 2016, it was observed that muddy water was cumulated in the puddles created from the uneven ground after road cleaning by water truck and rainfall.  However, 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.  (Contract 6)

 

Ÿ  10 July 2016 - A complaint was received from 1823, regarding dust and muddy trails at junction of Sha Tau Kok Road and Wo Keng Sha Road.  Also, it was suspected that water barriers were lack of maintenance, water leakage from water barriers occurred.  Site inspection was carried out on 14 and 15 July 2016 for the complaint investigation.  During the site inspection, no dusty materials were brought by vehicles from the site was observed.  As dust suppression measures, road cleansing by water bowsers was provided by the Contractors (both Contract 2 of DHK and Contract 6 of CCKJV) along Wo Keng Shan Road and Sha Tau Kok Road every day and the water trails on the road left after road cleansing was observed.  In view of the implemented mitigation measures such as wheel washing facilities and the cleanliness of roads condition during site inspection, it is considered that dust impact and muddy trails are not likely caused by the Contracts.  (Contract 2 and Contract 6)

 

Ÿ  14 July 2016 - A complaint was received from EPD, regarding muddy water was discharged at Sha Tau Kok Road.  Joint inspection was conducted by RE and Contractor of C6 (CCKJV) immediately on 13 July 2016.  In our investigation, there were no construction activities near the complaint location.  Therefore, it is considered that the muddy water discharge at Sha Tai Kok Road was not caused by the project.  Moreover, the complaint location is actually out of the site boundary.  To address the public concern, they had voluntarily carry out one-off cleaning of the drainage system of the concern area.  (Contract 6)

 

Ÿ  4 July 2016 - A complaint was received from ICC on 4 July 2016 regarding muddy water found on Lin Ma Hang Road.  According to the information provided, the complainant has already complained the same issue via 1823 on 20 June 2016 and the investigation report conducted by ET was issued on 13 July 2016.  In our previous investigation, it was addressed that Lin Ma Hang Road is a public road and frequent used by heavy vehicles and uneven ground was formed due to over usage.  Then, it may happen that muddy water was cumulated in the puddles created from the uneven ground after road cleansing by water truck and rainfall. To address public concern, CCKJV has already repaired the uneven ground by paving asphalt on 8 July 2016 to minimize the impact to the public.  Based on the findings from site observation, it is considered that the muddy water found on Lin Ma Hang Road was unlikely caused by the works of CCKJV.

 

Ÿ  22 July 2016 - A complaint was received from EPD on 22 July 2016 related to mud and slurry discharged out of the construction sites near Sha Tau Kok Road ¡V Ma Mei Ha and Wo Keng Shan Road when worker was washing a truck at the entrance of the construction site.  Secondly, two trucks outside the construction site along Wo Keng Shan Road pouring water which carried mud from the trucks during rainy day.  Site inspection was carried out by ET on 23 July 2016.  It was observed that wheel washing facilities were provided within the construction site and no mud or dusty materials would be brought by the vehicles out of the construction site.  For the second complaint, inspection was carried out along Wo Keng Shan Road during rainy day on 4 August 2016.  It was observed that all the dump trucks leaving the sites of C6 were properly covered and no muddy water leaking come from the dump trucks.  In our investigation, it is considered that the complaint was not related to the Contract. (Contract 2 and Contract 6)

 

9.1.2        Upon receipt of the complaint, follow up action has been undertaken by both Contractor promptly to resolve the complaints and deficiencies.  Investigation for the complaint was carried out by ET independently and the associated investigation reports were submitted to relevant parties.  In the Reporting Period, one (1) out of eleven (11) complaints was considered as project related.

11                Conclusions and Recommendations

11.1          Conclusions

11.1.1    This is the 12th Quarterly EM&A Summary Report presenting the monitoring results and inspection findings for the Reporting Period from 1 May 2016 to 31 July 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    In the Reporting Period, two noise complaints (one for Contract 2 and another for Contract SS C505) were received which triggered the Action Level exceedances.  The investigation reports for the complaints have been conducted by ET and it was concluded that both complaints were not related to the project.  The IR has submitted to relevant parties.

 

11.1.4    For water quality monitoring, a total of 103 Action Level (AL)/ Limit Level (LL) exceedances namely 53 AL/LL exceedances of turbidity and 50 LL exceedances of SS were recorded. The investigation reports for cause of exceedances were conducted by ET and submitted to relevant parties.  In the Reporting Period, 18 out of 103 exceedances were considered as project related and remedial action had undertaken by the Contractor.

 

11.1.5    During the Reporting Period, weekly joint site inspections for Contract 2, Contract 3, Contract 5, Contract 6, Contract 7 and Contract SS C505 were undertaken to evaluate the site environmental performance.  No non-compliances were observed during the weekly site inspection and environmental audit of the Reporting Period, indicating the implemented mitigation measures for air quality, construction noise and water quality were effective.  Minor deficiencies found in the weekly site inspection were in general rectified within the specified deadlines.  The environmental performance of the Project was therefore considered satisfactory.

 

11.1.6    In this Reporting Period, eleven (11) documented environmental complaints were received for the Project.   Upon receipt of the complaint, follow up action has been undertaken by both Contractor promptly to resolve the complaints and deficiencies.  Investigation for the complaint was carried out by ET independently and the associated investigation reports were submitted to relevant parties.  In the Reporting Period, one (1) out of eleven (11) complaints was considered as project related and remedial action had undertaken by the Contractor.

 

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

 

11.2          Recommendations

11.2.1    During wet season, 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    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.

 

11.2.3    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.
