(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 were 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 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 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 Turbidimeter 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.

6.2.4 In the Reporting Period, a total of ninety-two (92) Action/ Limit Level exceedances namely 48 exceedances of turbidity and 44 exceedances of SS were recorded. NOEs were issued to relevant parties upon confirmation of the results.

6.2.5 Investigation reports for the exceedance were conducted by the ET and the investigation results are summarized in Table 6-6. The detailed investigation reports have been presented in the relevant monthly EM&A reports.

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

Exceedance Day	Location	Exceeded Parameter	Cause of Water Quality Exceedance
1-Feb-16	WM2B	NTU & SS	Soil erosion and generation of run-off from the excavation area at North Portal was happened on 1 and 2 February 2016 during rainstorm. The exceedances were related to Contract 6. The Contractor had enhanced the mitigation measures such as covering the open slope as far as practicable to minimize muddy runoff and construction of sump pit to collect the site runoff. The construction of 2 new sump pits under the slopes and covering of open slopes were completed on 5 February 2016.
2-Feb-16	WM2B	NTU & SS
23-Feb-16	WM2B	NTU	The exceedances were due to the shallow water and the disturbance of sediment at river bed and unlikely related to the works under Contract 6.
25-Feb-16	WM2B	NTU & SS	The exceedances were related to the external turbid water emerged from the outlet pipe and unlikely due to the works under Contract 6.
26-Feb-16	WM4	NTU & SS	The Contractor of Contract 3 was conducted the removal work of the supporting of Bridge E on 26 February 2016. The removal of broken concrete by an excavator stirred up the river bed. The exceedances were related to Contract 3. The Contractor explained that in order to reinstate the river, this process is unavoidable. Since the river is fairly shallow in the dry season and working in the river inevitably disturbed the river bed, very few could be done to get rid of the impact. As to minimize the impact, the Contractor was managed to remove broken concrete in 3 days (25 to 27 February 2016). The construction activities carried out by Contract 2 was away from the river course and no discharge was made on 26 February 2016, it is considered that the exceedances were not related to Contract 2.
29-Feb-16	WM2B	NTU & SS	The exceedances were due to the shallow water and the disturbance of sediment at river bed and unlikely related to the works under Contract 6.
2 & 3 Mar 2016	WM2B (C6)	NTU & SS	A pipe carrying wastewater from bored piling to the nearest AquaSed was burst on 2 March 2016 and the untreated wastewater were getting into the open channel accidently. CCKJV has immediate halted the bored piling work until the damaged pipe was replaced. The exceedances were related to the pipe burst accident and unlikely related to the works under Contract 6.
4 Mar 2016	WM2B (C6)	NTU	The exceedances were due to the shallow water and the disturbance of sediment at river bed and unlikely related to the works under Contract 6.
5 Mar 2016	WM2B (C6)	NTU	Channel clearing was carried out on 5, 8, 9 and 10 March 2016 to remove the silt cumulated at the channel bed. The exceedances were due to insufficient mitigation measures during channel clearing. CCKJV should ensure the turbid water at the adjacent open channel was entirely blocked by the sand bag barrier or other means to prevent it flowing further downstream before carry out the channel cleaning.
8, 9 & 10 Mar 2016	WM2B (C6)	NTU & SS
4, 9 & 10 Mar 2016	WM1 (C5, C6 and SS C505)	NTU & SS	• C5 - There were no wastewater generation activities carried out on 4, 9 & 10 Mar 2016 and no discharge made into the river course. The exceedances were unlikely due to the Contract 5. • C6 - Turbid water was observed at upstream of the site area of Contract 6, the exceedances were unlikely due to the Contract 6. • SS C505 - The discharge point connecting public drainage under SS C505 would not flow to WM1 and its upstream, the exceedances were unlikely due to the SS C505.
11 Mar 2016	WM2A (C6)	NTU & SS	The condition of the water quality besides of Ping Yuen River of Bridge D under C6 on 1 Mar 2016 was normal and no turbid water was observed. There were no trails of turbid water discharge from the construction site, it is considered that exceedances were unlikely due to Contract 6.
11 Mar 2016	WM2B (C6)	NTU & SS	The water recirculation pump was detached from the water pipe accidentally and causing overflow of turbid water through the bar screen to downstream. The Contractor immediately fixed the detached recirculation pump and water pipe and the function of the recirculation pump was back to normal in the afternoon. It is concluded that the exceedances were a single incident.
14, 15 & 16 Mar 2016	WM2B (C6)	NTU & SS	The exceedances were due to the shallow water and the disturbance of sediment at river bed and unlikely related to the works under Contract 6.
21, 22, 23 & 24 Mar 2016	WM2B (C6)	NTU & SS	The effluent quality of C6 was visually acceptable. However, it was observed that muddy runoff from the public road surface into the existing channel due to rain. It is considered that the exceedances were related to cumulated silt at the river bed and muddy runoff from the public road surface and unlikely related to the works under Contract 6.
21 Mar 2016	WM4 (C2 & C3)	NTU & SS	• C2 & C3 - muddy water flowed from other upstream location which was not under monitored by the Contract was observed on 21 Mar 2016. It is considered that the exceedances were due to the stir up of sediment during rain and external muddy water from upstream and not related to the works under Contracts 2 & 3.
29, 30 & 31 Mar 2016	WM3 (C2 & C6)	NTU & SS	• C2 & C6 - discharge of turbid water and accumulated silt was observed from an unknown outfall which located at between the works area of C6 and WM3. It is considered that the turbid water detected at WM3 was related to the turbid discharge from the unknown outfall and unlikely due to the works under Contracts 2 and 6.
5^th, 6^th, 7^th, 8^th and 11^th April 2016	WM1 (C5, C6 and SS C505)	NTU & SS	Accumulation of rubbish were observed at the screening steel bar of box culvert near WM1 on 4 April 2016 after heavy rainstorm. Water flow near WM1 was therefore retarded and turbid water would be cumulated at WM1. Considered that the exceedances were unlikely related or due to the works of Contracts 5, 6 and SS C505.
11^th, 13^th, 14^th, 18^th, 19^th and 22^nd April 2016	WM2A (C6)	NTU and/or SS	Ÿ Since too much silt accumulated inside the sedimentation tank, the quality of effluent was not desirable and some turbid effluent was discharged into Ping Yuen River on 11^th April 2016. The exceedance should relate to Contract 6 since turbid effluent flowed into Ping Yuen River from working area. Ÿ A total rainfall 76.4 mm was recorded on 13 April 2016 and 23.7 mm on 18 April 2016. Due to the heavy rainfall, the soil slope at the river side was eroded and ran into the Ping Yuen River and muddy water was observed after passing the suspected soil erosion point. Hence, exceedances as recorded on 13^th, 14^th, 18^th, 19^th and 22^nd April 2016 are unlikely related the C6 construction activities.
7^th, 11^th, 14^th, 20^th, 22^nd, 23^rd, 25^th and 26^th April 2016	WM2B (C6)	NTU and/or SS	Ÿ Water monitoring on 7 April 2016 at WM2B, daily effluent self-monitoring was recorded visually clear. However, the silt cumulated at the channel bed or the screen gate was stirred-up by the flow of discharge from the AquaSed. Then the mixture of silt and treated water was overflow to the downstream. So the exceedance was not due to C6 construction activities. Ÿ On 11^th and 20^th April 2016, around 20mm shallow water deep encountered during water sampling. Moreover, the water flowing in the channel and the water samples collected at WM2B was observed visually clear. Consider that the water sample could not avoid inclusion of the loose sediment and debris and concluded the exceedance not due to C6 construction activities. Ÿ According to the site record from the monitoring team on 14 April 2016, very shallow water was measured at WM2B and the water depth was around 0.02m and water sampling during rainfall and it was observed that the water flowing in the open channel was slightly turbid due to stir up of sediment and cumulated silt at the river bed during rain. So, the exceedance was not due to C6 construction activities. Ÿ According to the site photos taken on 22, 23, 25 and 26 April 2016 by the ET, it was observed that the water samples collected at WM2B were turbid while water samples collected at WM2B-C were clear. As extracted from the Hong Kong Observatory, heavy rainfall was recorded 22^nd and 25^th April 2016. Hence, runoff was generated from the excavating areas during the rainfall and the turbid water was flowed into river channel. Thus, it is considered that the exceedances recorded on 22, 23, 25 and 26 April 2016 were related to runoff from the excavation work of site access construction.
2^nd, 20^th, 21^st and 22^nd April 2016	WM3 (C2 and C6)	NTU and/or SS	Ÿ The exceedance recorded on 2 April 2016 caused by turbid water discharge from the unknown outfall. Hence, the exceedance triggered unlikely due to the works under Contracts 2 and 6. Ÿ For investigation, the Contractor of C2 said that no discharge was made from the construction admin building. However, site inspection by RE, ET, IEC and the Contractor of C6 on 21 April 2016, the AquaSed (SH-8) which located upstream of W3, was found to have turbid treated effluent. As reported by the Contractor of C6, the AquaSed(SH-8) was running out of flocculent thus effectiveness of the water treatment was reduced. Hence, the exceedance triggered likely due to the works of Contract 6 for effluent discharge.

9 Non-compliance, Complaints, Notifications of Summons and Prosecutions

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 nine (9) documented environmental complaints which including one (1) complaint related Contract 3, one (1) complaint related Contract 2, six (6) complaints related Contract 6, and; moreover one (1) complaints as related Contract 2 and Contract 6. The summary of complaint received in the Reporting Period is listed below.

Ÿ 18 February 2016 - a complaint was received via 1823 regarding construction noise generated from the construction of flyover near Yuen Leng Village of Kau Lung Hang. In our investigation, it was observed that the complaint location is situated outside the site boundary of Contract 3. Moreover, there are several concurrent projects undertaking by other contractors, including the construction of flyover and road works which were not within the scope of Contract 3. It was concluded that the complaint was not related to the works under Contract 3. (Contract 3)

Ÿ 22 February 2016 - EPD notified CCKJV that a complaint was received with respect to the turbid river water observed in Ng Tung River near Contract 6¡¦s site office. In our investigation, it was observed that the AquaSed (SH-06) which adjacent to the wheel washing machine at Bridge A was not functioning properly due to excessive cleaning of dump trucks. Further enhancement of the wheel washing arrangement of Bridge A, such as deploy of new washing bay, additional sedimentation tanks and WetSep and sump pit modification, were implemented and the remedial works carried out by Contract 6 was acceptable and the ET will keep closely monitored the site performance. (Contract 6)

Ÿ 23 February 2016 - a complaint was received by CEDD regarding the soil/ debris brought by the dump trucks from the construction site running along Sha Tau Kok Road. In our investigation, no oil/debris was brought out by any trucks of LT/HYW was observed during site inspection and wheel washing facilities were implemented properly at all site exits. Moreover, there are many other dump trucks out of the project running along the Sha Tau Kok Road, particularly the Site Exit at Sha Tau Kok Road maintained by CCKJV, it was concluded that the complaint was unlikely to the Project. (Contract 6)

Ÿ 8 March 2016 - a complaint was received from 1823 regarding the generation of fugitive dust when heavy dump truck from construction site of Contract 2 (DHK) travelling on Sha Tau Kok Road. In our investigation, it is noted that water bowser for road cleaning has been providing on Sha Tau Kok Road and the route is between Wo Keng Shan Road (Admin Bldg Site) to Ping Che Roundabout which covered the complaint location. Moreover, apart from the project, there were many other heavy vehicles using the Sha Tau Kok Road and it was concluded that the dust problem on Sha Tau Kok Road was not likely due to the Contract. (Contract 2)

Ÿ 20 April 2016 - CEDD received a complaint from the Sha Tau Kok District Rural Committee expressing their concerns with respect to discharge of suspected untreated muddy water from the construction sites at Wo Keng Shan Road and Sha Tau Kok Road into the existing river channel. Inspection was carried out at construction sites at Wo Keng Shan Road and Sha Tau Kok Road to confirm that the Contractors have implemented proper mitigation measures and no muddy water was observed and being discharged from the site. It was concluded that the complaints were unlikely related to the Contracts. (Contracts 2 and 6)

Ÿ 22 April 2016 - CEDD received a complaint regarding to the direct discharge of wastewater into the manhole. In our investigation, a sedimentation tank was placed next to the manhole but it was idled and would only be used as a spare tank for emergency. As advised by CCKJV, all wastewater from that site area was stored in temporary pit and diverted to treat in wastewater treatment facilities including sedimentation tank and AquaSed and there is no discharge of wastewater into the drainage hole. The sedimentation tank was found removed from site on 26 April 2016. It was concluded that the complaint was not related to the contract. (Contract 6)

Ÿ 22 April 2016 - CEDD received a complaint from Sha Tau Kok District Rural Committee expressing their concerns with respect to pumping water from the exiting river channel near Ping Yuen Road for construction purpose without prior notice to villager and discharging suspected untreated muddy water into the river channel. As advised by CCKJV, water was extracted from the river channel for dust mitigation control measures. Inspection was carried out at upstream of the river and turbid water was observed but the source was unknown. It is considered that the quality of water in Ping Yuen River is not only affected by the construction activities but also the external factor such as rainfall and possible domestic discharge from the villager. It was concluded that the complaint was unlikely due to the Contract. (Contract 6)

Ÿ 21 April 2016 - a complaint was received from 1823 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 which 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. In our investigation, the Contractor had carried out dust suppression measures such as water spraying to minimize construction dust impact. Based on the observations from the site inspections and monitoring data, it is considered that the complaint regarding to dust is not evidenced. For the second concern, it was observed that the Contractor (C6) has provided AquaSed for wastewater treatment. Runoff from wheel washing was 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. 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 was not evidenced. (Contract 6)

Ÿ 28 April 2016 - a complaint was received from 1823 regarding to 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. In our investigation, the construction activities in the above locations were mainly bored piling work and the construction activity unlikely generates any chemicals that contaminate the soil and adversely affect the growth of crops. Moreover, the Contractor has provided mitigation measures such as site hoardings, concrete blocks, sandbags and temporary drainage to prevent any runoff/ discharge from the site. It was concluded that the complaint was unlikely related to the Contract. (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. 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. The investigation reports conducted by the ET were submitted to relevant parties.

Warning Letter

9.1.5 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.

11.1.2 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. Hence, one Action Level exceedance of construction noise was recorded in the Reporting Period. The investigation report for the complaint was conducted by ET and it was concluded that the complaint was not related to the project. The IR has submitted to relevant parties.

11.1.4 For water quality monitoring, a total of ninety-two (92) Action/ Limit Level exceedances namely 48 exceedances of turbidity and 44 exceedances of SS were recorded. NOEs were issued to relevant parties upon confirmation of the results. The investigation reports for cause of exceedances were conducted by ET and submitted to relevant parties.

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, nine (9) documented environmental complaints were received and lodged. Follow up actions have been undertaking by the Contractor to resolve the deficiencies. The investigation reports conducted by the ET were all completed and submitted to all relevant parties. In brief, all complaints were unlikely due to the project. However, the Contractor was reminded to fully implement the recommended mitigation measures as per the EM&A Manual.

11.1.7 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 explained that all dump trucks under the Contract were well covered before leaving the site, however, some drivers immediately opened the cover when they just get into Fill Bank and captured by the CCTV. The Contractor has issue warning letter to the relevant drivers to ensure no reoccurrence of similar case.

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

11.2 Recommendations

11.2.1 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.

11.2.2 The Contractor was also reminded to prevent muddy water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel and Ma Wat Channel or public area. Water quality mitigation measures to prevent surface runoff into nearby water bodies or public areas should paid attention and fully implemented.

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.
