Remarks:

(a) * Due to the presence of deployed silt curtain systems at the site boundaries of the Contract, some of the transect lines shown in Figure 2.4 could not be fully surveyed during the regular survey. Transect 10 is reduced from 6.4km to approximately 3.6km in length due to the HKBCF construction site. Therefore the total transect length for both NEL and NWL combined is reduced to approximately 108km.

(b) # Coordinates for transect lines 1, 2, 7, 8, 9 and 11 have been updated in respect to the Proposal for Alteration of Transect Line for Dolphin Monitoring approved by EPD on 19 August 2015.

(c) ^ The change of transect lines 2, 3, 4, 5, 6 and 7 and new transect line 24 were justified and verified by the ET Leader for Contract No. HY/2010/02 and the IEC respectively on 24 March 2017 and it was approved by EPD on 12 May 2017.

3 Environmental Monitoring and Audit

3.1 Air Quality Monitoring Results

The monitoring results for AMS6 and AMS7/AMS7B are reported in the monthly EM&A Reports (for January, February and March 2018) prepared for Contract Nos. HY/2011/03 and HY/2013/01 respectively.

Summary of Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level at AMS6 is reported in the monthly EM&A Reports (for January, February and March 2018) prepared by Contract No. HY/2011/03.

There was no Action and Limit Level exceedance of 1-hr TSP level and 24-hr TSP level recorded at station AMS7/AMS7B by the Environmental Team of Contract No. HY/2013/01 during the reporting period.

Two Action Level exceedances of 24-hour TSP level were recorded at stations AMS2 and AMS3B by the Environmental Team of Contract No. HY/2013/01 during the reporting period and investigated by the ET of the Contract.

Air quality exceedances recorded during the reporting period are summarised in Table 3.1.

Table 3.1: Action and Limit Level Exceedance for Air Quality

Date	Parameter	Station	Exceedance Recorded
17 Jan 2018	24-hour TSP	AMS2	Action Level
17 Jan 2018	24-hour TSP	AMS3B	Action Level

The details of the air quality exceedances can be referred to in the Monthly EM&A reports under Contract No. HY/2013/01.

Investigations into the exceedances were conducted and the findings are summarised below.

17 January 2018 (at AMS2 and AMS3B)

According to the Contractor of HY/2013/04, the major construction activities conducted under the Contract during the monitoring period included bridge segment delivery and erection, and construction of Box Culvert D.

As informed by the Contractor of HY/2013/04, watering of all main haul roads was provided in accordance with the HY/2013/04 site watering plan. This plan schedules water spraying for at least 8 times per day which follows the recommended mitigation measures in the EM&A Manual and Environmental Permit.

During ET’s regular weekly site inspection on 15 January 2018 (between 14:00 and 15:00), one air quality observation regarding a dry haul road at Bridge D1 was made; subsequently the Contractor provided water spray for this location and the observation was closed. The remaining haul roads were observed to be watered and no fugitive dust generation from HY/2013/04 works was observed during this inspection.

During the next ET regular weekly site inspection on 24 January 2018 (between 14:00 and 15:00), there was no air quality observation associated with watering of site areas.

Photos relating to the site inspections on 15 January 2018 and 24 January 2018 are presented in ET’s investigation report.

The wind data collected at the AMS3B wind station at Works Area WA2 during the monitoring period on 17 and 18 January 2018 shows that winds were still (averaged wind speed 0 m/s) during the monitoring period. This indicates that it was unlikely that the source of exceedances could be attributed to HY/2013/04.

Information available on EPD’s Air Quality Health Index (AQHI) website shows that the short-term health risk of air pollution between 08:00 a.m. on 17 January 2018 and 08:00 a.m. on 18 January 2018 was low to serious in Tung Chung (with maximum AQHI of 10+ at 13:00-19:00 on 17 January 2018). This, combined with the still winds recorded at the wind station, indicate that the background air pollution was relatively high during part of the monitoring period and may have contributed to the high level of TSP recorded. The AQHI data is available online at http://www.aqhi.gov.hk/epd/ddata/html/history/2018/201801_Eng.csv.

It was concluded that the exceedances were not due to HY/2013/04.

Silt curtains were provided at each box culvert for marine works areas in accordance with the approved Dolphin Watching Plan. The silt curtains were inspected regularly by ET and Contractor and the implementation was found to be in working order.

3.6 Advice on the Solid and Liquid Waste Management Status

The Contractor registered as a chemical waste producer for the Contract. Sufficient numbers of receptacles were available for general refuse collection and sorting. As a practical means, the disposal operation is managed by a single HKBCF contractor who is also responsible for applying dumping permit and its subsequent extension applications from EPD. Contract No. HY/2013/03 has been assigned to coordinate and arrange for disposal of extracted marine sediment from this Contract.

There was no generation of excavated sediment for treatment during this reporting period. Any treatment of excavated marine sediment will be conducted using cement solidification / stabilization (Cement S/S) techniques and the treated sediment will be reused onsite for either backfilling or landscaping (e.g. berm material).

The summary of waste flow table is detailed in Appendix G.

The Contractor was reminded that chemical waste containers should be properly treated and stored temporarily in designated chemical waste storage area on site in accordance with the Code of Practice on the Packing, Labelling and Storage of Chemical Waste.

3.6.1 Disposal of Marine Sediment Extracted from Bored Piling Works

3.6.1.1 Background

After the acceptance of the review of the approved Sediment Quality Report (SQR) for this Project under EPD letter dated 19 August 2015, an approval to dispose the marine sediment extracted from bored piling for this Project was then approved under memo from Secretary, Marine Fill Committee of CEDD dated 20 August 2015 for the disposal of marine sediment extracted from bored piling works. The disposal sites allocated to this Project are the Mud Pit CMP2 of the Confined Marine Sediment Disposal Facility to the South of The Brothers (or at the East of Sha Chau). As advised by CEDD in the memo dated 19 February 2016, from 00:00 on 22 March 2016 onward, the disposal space at CMP2 of the South of The Brothers is closed and all disposal of contaminated sediment is to be carried out at CMP Vd to the East of Sha Chau (ESC).

As Contract No. HY/2013/01 has commenced treatment of the extracted marine sediment, treatment will continue and the treated marine sediment will be re-used within the HKBCF Island. On the other hand, Contract Nos. HY/2013/02, HY/2013/03 and HY/2013/04 have not commenced the treatment of extracted marine sediment. Therefore the marine sediment extracted from these three Contracts will be disposed to the allocated disposal sites directly without treatment. As a practical means, the disposal operation is managed by one contractor who is also responsible for applying dumping permit and its subsequent extension applications from EPD. Contract No. HY/2013/03 has been assigned to coordinate and arrange for disposal of extracted marine sediment from all three Contracts.

The SQR was further reviewed in mid-2016. EPD has no comment to extend the validity of the SQR to August 2017 under letter dated 18 August 2016.

Based on the actual piling operation, the estimated quantity of marine sediment to be extracted has been revised from 85,000 m³ to 126,000 m³(bulk volume). EPD has no comments on the request as in the letter dated 20 October 2016. The Secretary of Marine Fill Committee, CEDD approved the increasing quantity in the memo dated 10 November 2016.

During the course of reviewing the SQR, it was noted that the contamination level of the marine sediment extracted from the inner part of the HKBCF Island was not identified during the previous sampling and testing. As requested by EPD, sampling and testing are required. The Sediment Sampling and Testing Proposal (SSTP) for the inner area of the HKBCF Island was approved by EPD on 2 June 2016.

As in the agreed SSTP for the inner area of the HKBCF Island, samples were taken from the seventeen batches of stockpiled marine sediments and from five boreholes each in one of the five sampling grids. After conducting chemical tests on samples, six batches of stockpiled samples under Contract No. HY/2013/03 and all eight batches of stockpiled samples under Contract No. HY/20013/04 are classified as Category L sediment. The Secretary of Marine Fill Committee of CEDD allocated disposal sites under memo dated 24 October 2016 and dated 22 November 2016 for disposal of a total of 9,500 m³ in-situ volume of Category L sediment (using a bulk factor of 1.3). The Category L sediment was disposed in December 2016.

One sample from the batch of stockpiled marine sediment under Contract No. HY/2013/03 and samples from all five sampling grids had contamination levels exceeding the Lower Chemical Exceedance Levels (LCEL) and biological screenings were carried out. All samples passed the biological screenings and are classified as Category Mp sediment and to be disposed off site using Type II confined marine disposal method the same method used for marine sediment extracted from other part of the HKBCF Island.

3.6.1.2 Dumping Arrangements

The barge for disposal of marine sediment will morn at the temporary loading and unloading at the east shore of the HKBCF Island, which has been being used by reclamation contractor (Contract No. HY/2010/02) for reclamation activities. In terms of safety consideration, each dumping date will be allocated to one Contract. The quantity of marine sediment disposed on the date is from one Contract.

During dumping, each Contractor is responsible for transporting the marine sediment from his site area to the barge. The estimated quantity of marine sediment in each truck is confirmed by Resident Site Staff of each Contract. The trip tickets for transportation and disposal of marine sediment are collected and checked. Contract No. HY/2013/03 as the dumping permit holder is responsible for reporting to EPD the quantity disposed of as the condition stipulated in the dumping permit.

3.6.1.3 Reporting

AECOM has confirmed that the disposal of excavated marine sediments to allocated dumping site via Contract No. HY/2013/03 has been completed with the last batch disposal on 30 August 2017. The total quantities disposed are presented in the following table (Table 3.4):

Table 3.4: Summary of Marine Sediment disposed to Dumping Site via Contract No. HY/2013/03

Month/Year	Type of Sediment and Quantity Disposed (m³)
	Cat. L (in Type I)	Type II
Total =	3,570	39,814

The complaint was about the regular absence of site staff at the wheel wash facility to clean the wheels of vehicles leaving HZMB BCF Island site after 19:00. A video of the area concerned was provided by the complainant.

The complaint was investigated by the ET of the Contract.

The relevant mitigation measures for washing of site vehicles for the HZMB BCF Island site, as required in the EMIS and statutory requirements in the Air Pollution Control (Construction Dust) Regulations and other applicable environmental legislation, are consolidated as follows:

● Immediately before leaving a construction site, every vehicle shall be washed to remove any dusty materials from its body and wheels and to ensure that no earth, mud or debris is deposited by them on roads.

● Vehicle washing facilities with high pressure water jet should be provided at every discernible or designated vehicle exit point. The area where vehicle washing takes place and the road section between the washing facilities and the exit point should be paved with concrete, bituminous materials or hardcores.

The wheel washing facility at the HY/2013/04 site boundary entrance/exit for vehicles leaving HY/2013/04 site in the direction of HZMB BCF Island site exit was implemented by the Contractor on 27 January 2018. A plan of the wheel washing facility is presented in Attachment 1 of ET’s investigation report. As informed by the Contractor of HY/2013/04, wheel washing facility was staffed by site workers with water hose between 07:00 and 19:00 only on each working day.

During ET’s regular weekly site inspection on 14 March 2018 (between 14:00 and 15:00), the haul road in the vicinity of the wheel wash facility was observed to be watered and no fugitive dust generation from HY/2013/04 works was observed. The additional signage mentioned above was also provided. Photos of implementation of these measures at the wheel wash facility are presented in Attachment 2 of ET’s investigation report. There were no observations referring to air quality mitigation measures associated with watering of site areas.

The Contractor was reminded to properly implement all necessary air and water quality mitigation measures identified in the EM&A Manual. All site vehicles leaving HY/2013/04 site should be properly washed at the wheel washing facilities at HY/2013/04 site exit to prevent muddy trail on the access roads and public roads thereafter.

The Contractor has agreed to provide 24 hours site workers with manual water spray at the wheel washing facility on each working day to ensure all vehicles have been washed before leaving the site.
