2 Summary of EM&A Programme Requirements

2.1 Monitoring Parameters

2.1.1 The EM&A Manual designated five monitoring stations to monitor environmental impacts on air quality and noise due to the Project. The monitoring locations are depicted in Figure 2.1.

2.1.2 The monitoring stations ID 4 & ID 5 will serve both the entire Development of Anderson Road (Schedule 3 Designated Project (DP)) project as well as the Widening of Po Lam Road (Schedule 2 DP) project.

2.2 Environmental Quality Performance Limits (Action/Limit Levels)

2.2.1 The environmental quality performance limits (i.e. Action/Limit Levels) were derived from the baseline air quality and noise monitoring results of Kwun Tong Government Secondary School (ID 1A), On Yat House (ID 2), Sau Nga House (ID 3), Sau Ming Primary School (ID 4) and Sau Mau Ping Catholic Primary School (ID 5) and / or as defined in the EM&A Manual for air quality and noise impacts.

2.2.2 The baseline condition of air quality (for ID 1A, ID 2 & ID 3) in the Project site was reviewed in August 2008 upon agreed by ER and IEC. Reviewed Action Levels for air quality at ID 1A, ID 2 and ID 3 were established in September 2008. The latest Action and Limit Levels (established in September 2008) for all monitoring parameters are summarized in Appendix C.

2.3 Environmental Mitigation Measures

2.3.1 Relevant environmental mitigation measures were stipulated in the Particular Specification and EP (No.: EP-140/2002) for the Contractor to adopt. A list of environmental mitigation measures and their implementation statuses are given in Appendix B.

3 MONITORING Results

3.1 Air Quality

3.1.1 Air quality monitoring, including 1-hr and 24-hr TSP, was conducted for at least three times every 6 days and for at least once every 6 days respectively at the 5 monitoring stations (ID 1A, ID 2, ID 3, ID 4 and ID 5), in accordance with the EM&A Manual.

3.1.2 Fifty-one (51) sessions of 1-hr TSP monitoring and seventeen (17) sessions of 24-hr TSP monitoring were conducted for the 5 monitoring stations (ID 1A, ID 2, ID 3, ID4 & ID5) in the reporting quarter.

3.1.3 The weather was mostly cloudy and sunny, with occasionally rainy days in the reporting quarter. The trend of impact air quality monitoring results for the reporting quarter is given in Appendix D. Major dust source included construction activities of the Project, concurrent construction activities of another project carried out in the vicinity and nearby traffic emissions.

3.1.4 All 1-Hour TSP results were below the Action and Limit Level in the reporting quarter. Three (3) exceedances of Action Level and one (1) exceedance of Limit Level were recorded in 20 January 2014 for 24-hour TSP monitoring at ID2, 3, 4 and 5 respectively. Exceedances were not related to project.

3.1.5 For the 24Hr TSP Action Level exceedances recorded at ID2, 4 and 5, results of 209.2mg/m3, 213.6mg/m3 and 237.6mg/m3 were recorded on 20 January 2014 (24-hr TSP).

According to information provided by the Contractor, concreting, installation of formwork, excavation and drainage works were the major construction activities being undertaken within works area of the Project during the monitoring period.

Dust mitigation measures have been implemented by the Contractor as listed below:-

· Main haul road were regularly watering by water trucks to maintain the surface wet;

· Continuous water spraying and tarpaulin sheet coverage was applied during excavation;

· Exposed slope surface should be either hydroseeded, shotcreted or covered up by tarpaulin;

· Vehicle washing facility was provided at vehicle exit points, and vehicle was washed to remove any dusty materials from its body and wheels before leaving.

Very close to the monitoring locations, there were contracts carrying out concrete mixing, excavation, rock breaking, pilling and drilling works at Portions A, B, C, D and Footbridge D in the works area during the course of monitoring. These works may probably contribute to the measured dust level at the Stations.

The dust exceedance was therefore considered not to be due to the Project works.

3.1.6 For the 24Hr TSP Limit Level exceedance recorded at ID3, a result of 282.6mg/m3, was recorded on 20 January 2014 (24-hr TSP).

According to information provided by the Contractor, concreting, installation of formwork, excavation and drainage works were the major construction activities being undertaken within works area of the Project during the monitoring period.

Dust mitigation measures have been implemented by the Contractor as listed below:-

· Main haul road were regularly watering by water trucks to maintain the surface wet;

· Continuous water spraying and tarpaulin sheet coverage was applied during excavation;

· Exposed slope surface should be either hydroseeded, shotcreted or covered up by tarpaulin;
