4 Water Quality Monitoring

4.1 Monitoring Requirements

4.1.1 Impact water quality monitoring was carried out to ensure that any deterioration of water quality was detected, and that timely action was taken to rectify the situation. For impact water quality monitoring, measurements were taken in accordance with the Contract Specific EM&A Manual. Table 4.1 shows the established Action/Limit Levels for the environmental monitoring works.

Table 4.1 Action and Limit Levels for Water Quality

Parameter (unit)	Water Depth	Action Level	Limit Level
Dissolved Oxygen (mg/L) (surface, middle and bottom)	Surface and Middle	5.0	4.2 except 5 for Fish Culture Zone
Dissolved Oxygen (mg/L) (surface, middle and bottom)	Bottom	4.7	3.6
Turbidity (NTU)	Depth average	27.5 or 120% of upstream control station’s turbidity at the same tide of the same day	47.0 or 130% of turbidity at the upstream control station at the same tide of same day
Suspended Solid (SS) (mg/L)	Depth average	23.5 or 120% of upstream control station’s SS at the same tide of the same day	34.4 or 130% of SS at the upstream control station at the same tide of same day and 10mg/L for Water Services Department Seawater Intakes

Notes:

(1) Depth-averaged is calculated by taking the arithmetic means of reading of all three depths.

(2) For DO, non-compliance of the water quality limit occurs when monitoring result is lower that the limit.

(3) For SS & turbidity non-compliance of the water quality limits occur when monitoring result is higher than the limits.

(1 m below water surface, mid-depth and 1 m above sea bed, except where the water depth is less than 6 m, in which case the mid-depth station may be omitted. Should the water depth be less than 3 m, only the mid-depth station will be monitored).

4.4 Monitoring Locations

4.4.1 In accordance with the Contract Specific EM&A Manual, thirteen stations (6 Impact Stations, 5 Sensitive Receiver Stations and 2 Control Stations) were designated for impact water quality monitoring. The six Impact Stations (IS) were chosen on the basis of their proximity to the reclamation and thus the greatest potential for water quality impacts, the five Sensitive Receiver Stations (SR) were chosen as they are close to the key sensitive receives and the two Control Stations (CS) were chosen to facilitate comparison of the water quality of the IS stations with less influence by the Project/ ambient water quality conditions.

4.4.2 Three water quality monitoring stations (SR5, IS10 and CS2) are located within Airport Approach (AA) Restricted Areas and permit is required to enter into these areas. The permit was issued on 24 November 2012 and the water quality monitoring work within AA restricted areas under this contract commenced on 24 November 2012. On 24 November 2012, the boat for sampling was broken after the mid-ebb tide sampling. Thus, the mid-flood tide sampling could not be conducted. The boat which is permitted to access AA restricted area was still under repair on 26 November 2012. Therefore, the water quality monitoring works were only carried out at the 10 stations outside AA restricted area during this period.

4.4.3 The locations of these monitoring stations are summarized in Table 4.4 and shown in
Figure 2.1.

Notes:
Monitoring Stations CS2, SR5 and IS10 are located within the Airport Approach Restricted Area. Therefore, a permit is required for entering into the area. The Contractor applied the permit in October 2012 and started to monitor since 24 November 2012.

4.5 Monitoring Methodology

4.5.1 Instrumentation

(a) The in-situ water quality parameters including dissolved oxygen, temperature, salinity and turbidity, pH were measured by multi-parameter meters.

4.5.2 Operating/Analytical Procedures

(a) Digital Differential Global Positioning Systems (DGPS) were used to ensure that the correct location was selected prior to sample collection.

(b) Portable, battery-operated echo sounders were used for the determination of water depth at each designated monitoring station.

(c) All in-situ measurements were taken at 3 water depths, 1 m below water surface, mid-depth and 1 m above sea bed, except where the water depth was less than 6 m, in which case the mid-depth station was omitted. Should the water depth be less than 3 m, only the mid-depth station was monitored.

(d) At each measurement/sampling depth, two consecutive in-situ monitoring (DO concentration and saturation, temperature, turbidity, pH, salinity) and water sample for SS. The probes were retrieved out of the water after the first measurement and then re-deployed for the second measurement. Where the difference in the value between the first and second readings of DO or turbidity parameters was more than 25% of the value of the first reading, the reading was discarded and further readings were taken.

(e) Duplicate samples from each independent sampling event were collected for SS measurement. Water samples were collected using the water samplers and the samples were stored in high-density polythene bottles. Water samples collected were well-mixed in the water sampler prior to pre-rinsing and transferring to sample bottles. Sample bottles were pre-rinsed with the same water samples. The sample bottles were then be packed in cool-boxes (cooled at 4^oC without being frozen), and delivered to ALS Technichem (HK) Pty Ltd. for the analysis of suspended solids concentrations. The laboratory determination work would be started within 24 hours after collection of the water samples. ALS Technichem (HK) Pty Ltd. is a HOKLAS accredited laboratory and has comprehensive quality assurance and quality control programmes.

4.7.3 During the reporting month, there are three Action Level exceedances and thirty-three Limit Level exceedances of suspended solids level. Nine Action Level exceedances and thirty-eight Limit Level exceedances of turbidity level were recorded. The completed “Notification of Environmental Quality Limit Exceedances” forms for all water quality exceedances are provided in Appendix M. No major marine works were carried out near the monitoring stations. Geotextile installation work, rock filling, silt curtains maintenance work and vessel maintenance work were being carried out within silt curtains near the restricted area during the sampling period. These activities were unlikely to cause adverse water quality impact. Therefore, all exceedances were considered as non-project related.

4.7.4 Water quality impact sources during the water quality monitoring were the construction activities of the Contract, nearby construction activities by other parties and nearby operating vessels by other parties.

4.7.5 The event action plan is annexed in Appendix F.

5 Dolphin Monitoring

5.1 Monitoring Requirements

5.1.1 Impact dolphin monitoring is required to be conducted by a qualified dolphin specialist team to evaluate whether there have been any effects on the dolphins.

5.2 Monitoring Methodology

Vessel-based Line-transect Survey

5.2.1 According to the requirements of the Updated EM&A Manual for HKLR (Version 1.0), dolphin monitoring programme should cover all transect lines in NEL and NWL survey areas (see Figure 1 of Appendix H) twice per month. The co-ordinates of all transect lines are shown in Table 5.1.

5.2.2 The survey team used standard line-transect methods (Buckland et al. 2001) to conduct the systematic vessel surveys, and followed the same technique of data collection that has been adopted over the last 16 years of marine mammal monitoring surveys in Hong Kong developed by HKCRP (see Hung 2012). For each monitoring vessel survey, a 15-m inboard vessel (Standard 31516) with an open upper deck (about 4.5 m above water surface) was used to make observations from the flying bridge area.

5.2.3 During on-effort survey periods, the survey team recorded effort data including time, position (latitude and longitude), weather conditions (Beaufort sea state and visibility), and distance travelled in each series (a continuous period of search effort) with the assistance of a handheld GPS (Garmin eTrex Legend).

5.2.4 Data including time, position and vessel speed were also automatically and continuously logged by handheld GPS throughout the entire survey for subsequent review.

5.2.5 When dolphins were sighted, the survey team would end the survey effort, and immediately record the initial sighting distance and angle of the dolphin group from the survey vessel, as well as the sighting time and position. Then the research vessel was diverted from its course to approach the animals for species identification, group size estimation, assessment of group composition, and behavioural observations. The perpendicular distance (PSD) of the dolphin group to the transect line was later calculated from the initial sighting distance and angle.

5.2.6 Survey effort being conducted along the parallel transect lines that were perpendicular to the coastlines (as indicated in Figure 1 of Appendix H) was labeled as “primary survey effort, while the survey effort conducted along the connecting lines between parallel lines was labeled as “secondary” survey effort. According to HKCRP long-term dolphin monitoring data, encounter rates of Chinese white dolphins deduced from effort and sighting data collected along primary and secondary liens were similar in NEL and NWL survey areas. Therefore, both primary and secondary survey effort were presented as on-effort survey effort in this report.

5.2.7 Encounter rates of Chinese white dolphins (number of on-effort sightings per 100 km of survey effort) were calculated in NEL and NWL survey areas in relation to the amount of survey effort conducted during each month of monitoring survey. Only data collected under Beaufort 3 or below condition would be used for encounter rate analysis. Dolphin encounter rates were calculated using primary survey effort alone, as well as the combined survey effort from both primary and secondary lines.

Photo-identification Work

5.2.8 When a group of Chinese White Dolphins were sighted during the line-transect survey, the survey team would end effort and approach the group slowly from the side and behind to take photographs of them. Every attempt was made to photograph every dolphin in the group, and even photograph both sides of the dolphins, since the colouration and markings on both sides may not be symmetrical.

5.2.9 Two professional digital cameras (Canon EOS 7D and 60D models), each equipped with long telephoto lenses (100-400 mm zoom), were available on board for researchers to take sharp, close-up photographs of dolphins as they surfaced. The images were shot at the highest available resolution and stored on Compact Flash memory cards for downloading onto a computer.

5.2.10 All digital images taken in the field were first examined, and those containing potentially identifiable individuals were sorted out. These photographs would then be examined in greater detail, and were carefully compared to the existing Chinese White Dolphin photo-identification catalogue maintained by HKCRP since 1995.

5.2.11 Chinese White Dolphins can be identified by their natural markings, such as nicks, cuts, scars and deformities on their dorsal fin and body, and their unique spotting patterns were also used as secondary identifying features (Jefferson 2000).

5.2.12 All photographs of each individual were then compiled and arranged in chronological order, with data including the date and location first identified (initial sighting), re-sightings, associated dolphins, distinctive features, and age classes entered into a computer database. Detailed information on all identified individuals will be further presented as appendix in the quarterly EM&A report.

5.3 Monitoring Results

Vessel-based Line-transect Survey

5.3.1 During the month of November 2012, four systematic line-transect vessel surveys were conducted on the 2^nd, 3^rd, 12^thand 13^th to cover all transect lines in NWL and NEL survey areas twice. The survey routes of each survey day were presented in Figures 2-6 of Appendix H.

5.3.2 From these surveys, a total of 296.6 km of survey effort was collected, with 93.2% of the total survey effort being conducted under favourable weather conditions (i.e. Beaufort Sea State 3 or below with good visibility) (Annex I of Appendix H). Among the two areas, 114.5 km and 182.1 km of survey effort were conducted in NEL and NWL survey areas respectively. In addition, the total survey effort conducted on primary lines (the vertical lines perpendicular to the coastlines) was 217.0 km, while the effort on secondary lines (the lines connecting the primary lines) was 79.6 km. Survey effort conducted on primary and secondary lines were both considered as on-effort survey data.

5.3.3 During the the two sets of monitoring surveys in November 2012, a total of 27 groups of 68 Chinese White Dolphins were sighted (Annex II of Appendix H). All except four of these sightings were made during on-effort search. Twenty-one on-effort sightings were made on primary lines, while another two on-effort sightings were made on secondary lines. All dolphin groups were not associated with any operating fishing vessel during the November’s surveys.

5.3.4 Distribution of these dolphin sightings made during November’s survey was shown in Figure 6 of Appendix H. These sightings were mainly concentrated in the northwestern end of North Lantau waters (i.e. near Lung Kwu Chau, Sha Chau and Pillar Point), while the rest were scattered to the northeast corner of airport platform, near Siu Mo To, Yam O and Sham Wat (Figure 6 of Appendix H).

5.3.5 Notably, no dolphin sighting was made near the HKLR03 construction site during this month’s monitoring surveys (Figure 6 of Appendix H).

5.3.6 During November’s surveys, dolphin encounter rates deduced from survey effort and sighting data from primary lines only were 13.4 and 4.1 sightings per 100 km of survey effort in NWL and NEL survey areas respectively. On the other hand, dolphin encounter rates deduced from survey effort and sighting data collected from both primary and secondary lines were 10.5 and 4.4 sightings per 100 km of survey effort in NWL and NEL survey areas respectively.

5.3.7 The average group size of Chinese white dolphins was 2.5 individuals per group during November’s surveys. Moreover, the average group sizes of dolphins in NWL and NEL were 2.5 and 2.6 individuals per group respectively.

Photo-identification Work

5.3.8 A total of 44 re-sightings of known individual Chinese White Dolphins were made during the November’s surveys (Annexes III and IV, and Photo Identified Record of Appendix H). Among these 44 re-sightings, 33 individuals were identified, with nine individuals being re-sighted twice and one individual (NL220) being re-sighted three times during the month.

5.3.9 Notably, both CH34 and NL220 were re-sighted twice on the same day (i.e. November 2nd) together with another unknown juvenile. Therefore, for encounter rate analysis and abundance estimation, the second sighting with these individuals on November 2nd will be adjusted in order to avoid double-counting issue.

5.3.10 During November’s surveys, five well-recognized females, NL93, NL98, NL188, NL202 and NL242, were accompanied with their calves during their re-sightings.

Conclusion

5.3.11 During this month of dolphin monitoring, no adverse impact from the activities of this construction project on Chinese white dolphins was noticeable from general observations.

5.3.12 Due to monthly variation in dolphin occurrence within the study area, it would be more appropriate to draw conclusion on whether any impacts on dolphins have been detected related to the construction activities of this project in the quarterly EM&A report, where comparison on distribution, group size and encounter rates of dolphins between the quarterly impact monitoring period (October-December 2012) and baseline monitoring period (3-month period) will be made.

6 ENVIRONMENTAL SITE INSPECTION AND AUDIT

6.1 Site Inspection

6.1.1 Site Inspections were carried out on a weekly basis to monitor the implementation of proper environmental pollution control and mitigation measures for the Project. During the reporting month, 4 site inspections were carried out on 6, 13, 20 and 30 November 2012.

6.1.2 Particular observations during the site inspections are described below.

6 November 2012

(a) Debris was removed from the deck of the barge in Portion X. (This observation was found on 30 October 2012 and was closed on 6 November 2012.)

(b) Bare soils were found in dry condition at West Portal. The Contractor should spray dry bare soils with water frequently (This observation was closed on 13 November 2012.)

(c) Stockpiles of excavated materials were found uncovered at Airport Road. The Contractor was reminded to cover or water the excavated materials at Airport Road in the dry season. According to the Contractor, using impervious sheeting to cover such materials or spraying the materials with water are not appropriate at this site. This is because the Airport Authority Hong Kong (AAHK) concerns about the safety issue of blowing away of impervious sheeting to cause accidents and there is no valid water use permit for this site. In this case, sand bags will be provided and placed as a cover to such materials to minimise the dust impact. (This observation was closed on 13 November 2012.)

(d) Silt was found on the site access road at Airport Road. The Contractor should remove the silt. (This observation was closed at on 13 November 2012)

(e) Dust was generated during filling of rock materials into sea in Portion X. The Contractor should spray the rock fill materials with water to suppress dust emission. (This observation was closed on 13 November 2012.)

(f) Stock of cement bags were found improperly covered at Kwo Lo Wan Road. The Contractor was reminded to cover the stock of cement bags properly. According to the Contractor, use of impervious sheeting as a cover for cement bags is not appropriate at this site as the AAHK concerns about the safety issue of blowing away of impervious sheeting to cause accidents. In this case, sand bags will be provided and placed as a cover to the stock of cement bags to minimise the dust impact. (This observation was closed on 13 November 2012.)

(g) Storage area with inadequate capacity was found at Kwo Lo Wan Road. The Contractor was reminded to provide a larger drip tray for storage of oil barrels as possible. (This observation was closed on 13 November 2012.)

(h) A stagnant pool was found at Kwo Lo Wan Road. The Contractor was suggested to apply larvicide sand to prevent mosquito breeding. (This observation was closed on 13 November 2012.)

(i) Leaking of water from damaged drain was found on the vegetation of Airport Road works area, and stagnant pools were found on the affected vegetation. (This observation was closed on 13 November 2012.)

13 November 2012

(a) The unpaved roads were found in dry condition at Works Area 03. The Contractor should spray unpaved roads with water frequently. (This observation was closed on 20 November 2012.)

(b) The unpaved roads were found in dry condition at West Portal. The Contractor should spray unpaved roads with water frequently. (This observation was closed on 20 November 2012.)

(c) The compressor was found to be without a drip tray at Kwo Lo Wan Road. The Contractor was reminded to provide a drip tray for the compressor.

(d) The oil drum was found to be with a drip tray at West Portal. The Contractor was reminded to provide a drip tray for the oil drum. (This observation was closed on 20 November 2012.)

(e) Dusty materials were found at Works Area 04. The Contractor was reminded to keep works area clean and tidy. (This observation was closed on 20 November 2012.)

20 November 2012

(a) No cover was provided for the excavated materials at Kwo Lo Wan Road. The Contractor should provide covers for excavated materials to prevent fugitive dust impact. (This observation was closed on 30 November 2012.)

(b) The sound abosbing materials for noise reduction and tarpaulin sheets for dust prevention provided for the mounted excavated breaker were found to be in poor condition at West Portal. The Contractor should provide proper noise reduction materials and tarpaulin sheets for the mounted excavated breaker. (This observation was closed on 30 November 2012.)

(c) Lids were not provided for the Barrels on the 2001 Chang Sing Vessel. The Contractor was reminded to provide lids for the Barrels. (This observation was closed on 30 November 2012.)

(d) The lubricative container did not have a drip tray at Airport Road. The Contractor was reminded to provide a drip tray for the lubricative container. (This observation was closed on 30 November 2012.)

(e) The drip tray was found to be filled with water and other soil materials at West Portal. The Contractor was reminded to clear soil and water inside the drip tray. (This observation was closed on 30 November 2012.)

(f) The U- drainage was found to be filled with excavated materials and leaves at Kwo Lo Wan Road. The Contractor was reminded to clear excavated materials and leaves inside the U- drainage. (This observation was closed on 30 November 2012.)

30 November 2012

(a) Environmental Permits/ Licences were not provided at the site entrance at Kwo Lo Wan Road. The contractor was reminded to provide Environmental Permits/ Licences at all site entrance for readily inspection.

6.1.3 The Contractor has rectified most of the observations as identified during environmental site inspections during the reporting month. Follow-up actions for outstanding observations will be inspected during the next site inspections.

6.2 Advice on the Solid and Liquid Waste Management Status

6.2.1 The Contractor had submitted application form for registration as a chemical waste producer for the Project. Sufficient numbers of receptacles were available for general refuse collection and sorting.

6.2.2 Monthly summary of waste flow table is detailed in Appendix I.

6.2.3 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 Practise on the Packaging, Labelling and Storage of Chemical Wastes.

6.3 Environmental Licenses and Permits

6.3.1 The valid environmental licenses and permits during the reporting month are summarized in Appendix K.

6.4 Implementation Status of Environmental Mitigation Measures

6.4.1 In response to the site audit findings, the Contractors carried out corrective actions.

6.4.2 A summary of the Implementation Schedule of Environmental Mitigation Measures (EMIS) is presented in Appendix L. Most of the necessary mitigation measures were implemented properly.

6.4.3 Regular marine travel route for marine vessels were implemented properly in accordance to the submitted plan and relevant records were kept properly.

6.4.4 Dolphin Watching Plan was implemented during the reporting month. No dolphins were observed. The relevant records were kept properly.

6.4.5 A dolphin exclusion zone of 250m was implemented during the installation of silt curtains on 21 and 22 November 2012. No dolphins were observed. The relevant records were kept properly.

6.5 Summary of Exceedances of the Environmental Quality Performance Limit

6.5.1 For 1-hour TSP and 24- hour TSP, no Action and Limit Level exceedances were recorded at AMS 5 and AMS 6 during the reporting month.

6.5.2 For construction noise, there is one Action Limit exceedance. No Limit Level exceedances were recorded at the monitoring station during the reporting month.

6.5.3 During the reporting month, there are three Action Level exceedances and thirty-three Limit Level exceedances of suspended solids level. Nine Action Level exceedances and thirty-eight Limit Level exceedances of turbidity level were recorded. No major marine works were carried out near the monitoring stations. Geotextile installation work, rock filling, silt curtains maintenance work and vessel maintenance work were being carried out within silt curtains near the restricted area during the sampling period. These activities were unlikely to cause adverse water quality impact. Therefore, all exceedances were considered as non-project related.

6.6 Summary of Complaints, Notification of Summons and Successful Prosecution

Nine Action Level exceedances and thirty-eight Limit Level exceedances of turbidity level were recorded. No major marine works were carried out near the monitoring stations. Geotextile installation work, rock filling and silt curtains maintenance work and vessel maintenance work were being carried out within silt curtains near the restricted area during the sampling period. These activities were unlikely to cause adverse water quality impact. Therefore, all exceendances were considered as non-project related.

8.1.5 A total of 44 re-sightings of known individual Chinese White Dolphins were made during the November’s surveys. Among these 44 re-sightings, 33 individuals were identified, with nine individuals being re-sighted twice and one individual (NL220) being re-sighted three times during the month.

8.1.6 Notably, both CH34 and NL220 were re-sighted twice on the same day (i.e. November 2^nd) together with another unknown juvenile. Therefore, for encounter rate analysis and abundance estimation, the second sighting with these individuals on November 2^nd will be adjusted in order to avoid double-counting issue.

8.1.7 During November’s surveys, five well-recognized females, NL93, NL98, NL188, NL202 and NL242, were accompanied with their calves during their re-sightings.

8.1.8 During this month of dolphin monitoring, no adverse impact from the activities of this construction project on Chinese white dolphins was noticeable from general observations.

8.1.9 Environmental site inspection was carried out on 6, 13, 20 and 30 November 2012. Recommendations on remedial actions were given to the Contractors for the deficiencies identified during the site inspections.
