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 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 E1, which showed that the portable direct reading dust meter is capable of providing comparable results with that provided by a HVS.

Remarks:
(a)	The exceedance was not considered as caused by the construction of the Project due to areas of reclamation related marine works undertaken under the Project were surrounded by silt curtain which were inspected daily by the Contractor and inspected periodically by ER.  The silt curtain nearby the water quality monitoring stations was observed to be in good condition/well-functioning.
(b)	The exceedance was not considered as caused by the construction of the Project due to no illegal discharge/sediment plume was observed nearby the water quality monitoring station during the sampling in mid-ebb/mid-flood tide.

Based on the investigations conducted for each of the monitoring day with exceedances, the exceedances of SS were not likely caused by the work activities related to the Project.

Nevertheless, the Contractors were reminded to implement all relevant mitigation measures for the marine works, including regular checking of silt curtain integrity, provide periodic maintenance and maintain good site practice.  The ET will keep on checking monitoring data, plant, equipment and Contractor’s working methods.
