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/m^3	Limit Level, µg/m^3
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.

2.3.1 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.

Table 2.7        Action and Limit Levels for Water Quality

Parameters	Action Level	Limit Level
DO in mg/L (Surface, Middle & Bottom)	Surface and Middle 5.9 mg/L^[1] Bottom 5.6 mg/L	Surface and Middle 4 mg/L^[1] Bottom 2 mg/L
SS in mg/L(Depth-averaged)	13.5 mg/L or 120% of upstream control station at the same tide of the same day, whichever is higher.^[2]	23.5 mg/L or 130% of upstream control station at the same tide of the same day, whichever is higher.^[2]
Turbidity in NTU(Depth-averaged)	17.1 NTU or 120% of upstream control station at the same tide of the same day, whichever is higher.^[2]	23.5 NTU or 130% of upstream control station at the same tide of the same day, whichever is higher.^[2]

Notes:

(1) For DO, non-compliance occurs when monitoring results is lower than the limits.

(2) For SS and Turbidity, non-compliance occurs when monitoring results is larger than the limits

2.7 Implementation Status of Environmental Mitigation Measures

A summary of the Environmental Mitigation Implementation Schedule is presented in Annex B.  The necessary mitigation measures were implemented properly for the Project.

2.8 Summary of Exceedances of the Environmental Quality Performance Limit

Results for air quality monitoring (1-hour TSP) complied with the Action/ Limit levels in the reporting period.  Three (3) Action level exceedances for construction noise were recorded from three (3) environmental complaints related to noise nuisance.  No Project-related Action/ Limit level exceedances were recorded for water quality after preliminary investigation. 

Cumulative statistics on exceedances is provided in Annex G.

2.9 Summary of Complaints, Notification of Summons and Successful Prosecutions

There was no notification of summons or prosecution recorded in the reporting period.  There was no reporting change in the reporting period.

One (1) environmental complaint related to dust and noise nuisances from demolition of the site office near Man Tung Road on 4 October 2018 and two (2) environmental complaints related to construction noise nuisance from barges were received on 4 and 5 October 2018 were received during the reporting period.  Investigations were conducted for each of the environmental complaints in accordance with the complaint handling process as stated in the Complaint Management Plan. 

Based on the information provided by the ER and the Contractor, supplemented the regular/ad-hoc site inspection conducted at the site office, there was no exceedance of air quality and noise limit levels and non-compliance was not observed.  It was observed that the Contractor had implemented mitigation measures included water spraying to control dust emission.  The hammer portion of the breaker was also wrapped with soundproof mat to reduce noise impact.  Nevertheless, the Contractor was reminded to implement all relevant mitigation measures of dust and noise impact to avoid causing unnecessary nuisance at all other active works area.  The ET will continue to check the implementation status of the mitigation measures.

Based on the information provided by the ER and the Contractor, supplemented the regular/ad-hoc site inspections, it is considered that the Contractor followed the requirements stated in the Construction Noise Permits (CNPs) and implemented adequate noise mitigation measures.  To further minimise the noise nuisance to nearby residential areas, relocation of barges would not be conducted within the restricted hours, unless additional noise mitigation measures would be implemented.  Nevertheless, the Contractor was reminded to strictly follow the requirements stated in the CNPs and implement noise mitigation measures.

Statistics on complaints, notifications of summons, successful prosecutions are summarised in Annex G.
