2 EM&A Results for Tung Chung East

The EM&A programme for the Project required environmental monitoring for air quality, noise, water quality and marine ecology as well as environmental site inspections for air quality, noise, water quality, waste management, marine ecology and landscape and visual impacts. The EM&A requirements and related findings for each component are summarized in the following sections.

2.1 Air Quality

2.1.1 Monitoring Requirements and Equipment

According to the Updated EM&A Manual ([3]) of the Project, impact air quality monitoring in terms of 1-hour Total Suspended Particulate (TSP) was conducted three (3) times every six (6) days when the highest dust impact was expected. The Action and Limit Levels of the air quality monitoring is provided in Table 2.1 below.

Table 2.1 Action and Limit Levels for 1-hour TSP

Location	Action Level, µg/m³	Limit Level, µg/m³
Monitoring station for Tung Chung East	279	500

Portable direct reading dust meters were used to measure 1-hour TSP levels in undertaking the air quality monitoring for the Project. The proposed use of portable direct reading dust meters was submitted to IEC and obtained agreement from the IEC as stated in Section 5.5 of the Updated EM&A Manual. With the use of direct reading dust meter, it can allow prompt and direct results for the EM&A reporting and the implementation of the event and action plan. The portable direct reading dust meter would be calibrated every year against High Volume Sampler (HVS) to check the validity and accuracy of the results measured by direct reading method.

The monitoring location and equipment used in the impact air quality monitoring programme are summarized in Table 2.2 and illustrated in Figure 2.1. Copies of the calibration certificates for the equipment are presented in Annex D1, which showed that the portable direct reading dust meter is capable of providing comparable results with that provided by a HVS.

2.3 Water Quality Monitoring

2.3.1 Monitoring Requirements and Equipment

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. Impact water quality monitoring was undertaken three days per week since the commencement of marine works during the reporting period in accordance with the Updated EM&A Manual. Each impact water quality monitoring was scheduled such that the interval between two impact water quality monitoring was more than 36 hours to record representative water quality data throughout the week during the marine works.

Two (2) replicate in-situ measurements and samples were collected at each monitored water depth of each designated monitoring stations. Dissolved Oxygen (DO), pH value, salinity, temperature and turbidity were measured in-situ whereas the level of suspended solids (SS) were determined by ALS Technichem (HK) Pty Ltd which is a HOKLAS accredited laboratory.

The Action and Limit Levels of the water quality monitoring are provided in Table 2.7.

Ÿ Monitoring stations are located upstream/far away from the Project works area.

Based on the preliminary investigation conducted for each of the monitoring day with potential action level exceedances with the Contractor, the ER and the IEC, there is no evidence showing the exceedances were related to the Project. Nevertheless, the Contractor was reminded to implement all relevant mitigation measures for the marine works, including regular checking of silt curtain integrity and maintain good site practice. The ET will keep on checking monitoring data, plant, equipment and Contractor’s working methods. The ET will also conduct further investigation, including the review of water quality monitoring data from adjacent projects, to substantiate the exceedances were not considered as caused by the construction of the Project.

2.4 Soft Shore Ecological Monitoring

2.4.1 Monitoring Requirements

According to the Updated EM&A Manual ([7]) of the Project, impact soft shore ecological monitoring has to be conducted quarterly at each survey location at Tung Chung Bay (TCB) and Tai Ho Wan (THW) covering wet and dry seasons during the marine construction of the Project. The soft shore ecological monitoring consisted of qualitative walk-through surveys, quantitative transect surveys and sedimentation rate monitoring at the accessible survey locations of TCB and THW.

For qualitative walk-through surveys, the accessible shoreline of TCB and THW at each of the three shore heights: 2 m, 1.5 m and 1 m above Chart Datum was surveyed, and organisms encountered were recorded and their relative abundance noted. In particular, active search of horseshoe crabs and seagrasses were conducted to confirm whether these species are present along the sites.

For quantitative transect survey, one 50 – 100 m horizontal (belt) transect (actual length subject to the site conditions) was surveyed at each of the three shore heights: 2 m, 1.5 m and 1 m above Chart Datum of each survey location. On each transect, five quadrats (50 cm x 50 cm) were placed randomly in each transect to assess the abundance and distribution of flora and fauna. For each quadrat, surface layer to 5 cm depth was sieved and microbenthic organisms (e.g. crustaceans) were recorded and identified. Density of organisms was expressed as individuals / m². Areas with seagrass were also recorded and identified and other information, such as the percentage cover, were also recorded. Sessile animals such as barnacles and oysters in each quadrat were not counted but estimated as percentage cover on the rock surface. All species of algae (encrusting, foliose and filamentous) were also identified and recorded by estimating the percentage cover on the rock surface. All organisms were identified to the lowest possible taxonomic level (at least Genus level). Species encountered outside the quadrat but in the vicinity of survey transect were also recorded.

For sedimentation rate monitoring, to avoid disturbance to the mudflat and nuisance to navigation, no fixed marker/monitoring rod was installed at the monitoring stations. A high precision Global Navigation Satellite System (GNSS) real time location fixing system (or equivalent technology) was used to locate the station in the precision of 1 mm, which is reasonable under flat mudflat topography with uneven mudflat surface only at micro level.

Measurements were taken directly on the mudflat surface. The Real Time Kinematic GNSS (RTK GNSS) surveying technology was used to measure mudflat surface levels and 3D coordinates of a survey point. The RTK GNSS survey was calibrated against a reference station in the field before and after each survey. The reference station is a survey control point established by the Lands Department of the HKSAR Government or traditional land surveying methods using professional surveying instruments such as total station, level and/or geodetic global navigation satellite system. The coordinates system is in HK1980 GRID system. The reference control station was surveyed and established by traditional land surveying methods using professional surveying instruments such as total station, level and/or geodetic GNSS. The accuracy was down to mm level and higher than the proposed RTK GNSS cm level so that the reference control station has relatively higher accuracy. As the reference control station has higher accuracy, it was set as true evaluation relative to the RTK GNSS measurement. All position and height correction were adjusted and corrected to the reference control station.

The precision of the measured mudflat surface level reading (vertical precision setting) was within 10 mm (standard deviation) after averaging the valid survey records of the XYZ HK1980 GRID coordinates. Each survey record at each station was computed by averaging at least three measurements that are within the above specified precision setting. Both digital data logging and written records were collected in the field. Field data on station fixing and mudflat surface measurement were recorded.

2.4.2 Monitoring Schedule for the Reporting Month

The schedule for soft shore ecological monitoring during the reporting period is provided in Annex G1.

2.4.3 Results and Observations

Impact soft shore ecological monitoring was conducted at three (3) monitoring locations at Tung Chung Bay (TCB), situated in the eastern side (TCB1), southern side (TCB2) and western side (TCB3) as well as one (1) monitoring location at Tai Ho Wan (THW) as shown in Figure 2.4 during the reporting period. Representative photographs taken during the impact monitoring are presented in Figure 2.5.

For qualitative walk-through surveys, horseshoe crabs and intertidal soft shore communities were recorded while seagrass beds were not observed during the impact monitoring. The survey results for each monitoring location are summarized in Table 2.11 below and detailed in Annex G2.

Table 2.11 Summary of Qualitative Walk-through Surveys

Date and Time (^[[8]⁾)	Location	No. of Species	No. of Individuals	No. of Species	Area Coverage (m²)	No. of Other Intertidal Species
4/12/2018 10:15-13:30	THW	1	17	0	0	43
5/12/2018 13:30-16:00	TCB1	1	1	0	0	45

5/12/2018 13:30-16:00	TCB3	1	3	0	0	32

For quantitative transect surveys, a total of 5,252 individuals were recorded from all transects at monitoring stations TCB1-3 and THW. The most abundant group of intertidal soft shore communities recorded was gastropods, with a total of 5,082 individuals (relative abundance of 96.8% and density of 339 individual m^-2). The summary of the top three dominant species at each shore height of each monitoring station and the complete list of species and density recorded are presented in Annex G2. When compared with the results obtained during the baseline monitoring as presented in the Baseline Monitoring Report ([9]), higher number of intertidal species were recorded at each monitoring location, though the abundance / density of intertidal communities was observed to be lowered. Nevertheless, there is no indication of change in composition of intertidal communities during the reporting period.

The mudflat surface levels at the four selected monitoring stations in December 2018 and the corresponding XYZ HK1980 GRID coordinates are presented in Table 2.12. When compared with the results obtained during the baseline monitoring as presented in the Baseline Monitoring Report ([10]), the sediment levels at most monitoring station generally increased, except for TCB 2. The ET will continue to observe the trend of change in sediment levels over time for further comparison and review..

Table 2.12 Results of Sedimentation Rate Monitoring

Monitoring Station	Northing (m)	Easting (m)	Z level at Dec 2018 (mPD)	Remarks
TCB1	816068.621	811129.312	1.271	Soft mudflat
TCB2	815812.393	810917.285	1.100	Soft mudflat

THW	817472.066	815850.401	1.072	Soft mudflat

The impact monitoring results showed that there was no evidence showing significant change in intertidal communities when compared against the data obtained during baseline monitoring. No action is thus required to be undertaken in accordance with the Event and Action Plan presented in Annex G3. The ET will continue to observe the change in density or the distribution pattern of horseshoe crab, seagrass and intertidal soft shore communities taking into account natural fluctuation in the occurrence and distribution pattern such as due to seasonal change.

2.5 EM&A Site Inspection
