3 IMPACT MONITORING

3.1 Air Quality

24-Hour TSP Levels Monitoring

The sampling procedure follows that described in the App. B of Pt 50 in 40CFR Ch.1 (U.S.Environmental Protection Agency). TSP is sampled by drawing air through aconditioned, pre-weighed filter paper inside the high volume sampler at a controlled rate.After 24-hour sampling the filter paper with retained particles is collected and returned tothe laboratory for drying in a desiccator followed by weighing. TSP levels are calculatedfrom the ratio of the mass of particulate retained on the filter paper to the total volume ofair sampled.

12

The samplers should be properly maintained. Prior to dust monitoring commencing,appropriate checks should be made to ensure that all equipment and necessary powersupply are in good working condition.

Calibration Requirements

The flow rate of the high volume sampler with mass flow controller will be calibratedusing an orifice calibrator. Initial calibration (five points) will be conducted uponinstallation and prior to commissioning. Calibration will be carried out every six months.Calibration certificates are attached in Appendix E.

To examine the construction dust levels, 24-hour TSP monitoring was undertakenaccording to the EM&A Manual. The dust monitoring locations are shown in theSection 2.2 above. Monitoring results are presented in the following table and AppendixF for graphical plot. The 24-hour TSP monitoring results in the range from 28.5 to 109.1ug/m3 recorded in the monitoring period shows that the dust levels generated by theactive construction activities were within the Action Levels with no exceedance. Thisindicates that the construction activities did not have a noticeable adverse effect on thegeneral air quality for the works areas.

3.2 Noise

B&K 2250 sound level meters which complied with the International ElectrotechnicalCommission Publication 651:1979 (Type 1) and 804:1985 (Type 1), specification asreferred to in the Technical Memoranda to the NCO were used for the construction noiseimpact monitoring. The B&K sound level meters and B&K 4231 calibrator are verifiedby the certified laboratory or manufacturer once every two years to ensure they perform tothe same level of accuracy as stated in the manufacturer’s specifications. In thisreporting period, two sound level meters with serial number 2731886 and 2741136 wereused. All relevant calibration certificates are attached in Appendix E.

Immediately prior to and following each set of measurements at any NSR, the accuracy ofthe sound level meter was checked using an acoustic calibrator generating a known soundpressure level at a known frequency. If the calibration levels before and after themeasurement differs by more than 1.0dB the measurement shall be repeated to obtain areliable result. Periods of prolonged or repeated overloading of the sound level meterdetector were avoided by setting the meter with adequate headroom prior to commencingmeasurements. Measurements were recorded to the nearest whole dB, with values of 0.5

14

or more being rounded up.

Impact noise monitoring of LAeq(30min) was undertaken to measure construction noiselevels in accordance with the EM&A Manual. The noise monitoring locations are shownin Section 2.2 above.

The monitoring results corrected to the baselines in the range from 60 to 75 dBA arepresented in the following table and Appendix F for graphical plot.

11 SITE INSPECTIONS

11.1 Observations

Regular site inspections led by the Engineer’s Representative and anticipated by ET andrespective Contractors were undertaken in accordance with the EM&A Manual in thereporting period. The contractors' performance on environmental matters were assessedand found in an acceptable manner. The inspection findings and the associatedrecommendations on improvement to the environmental protection and pollution controlworks were raised to the contractors for reference and/ or action.

Observations against the implementation of the mitigation measures recommended in theEP/EIA are summarized as follows:

Item Description Follow-upStatus

Contract 10011 The contractor is reminded to clean the oil stain left on the ground

at Works Site C.Completed

2 The contractor was reminded to carry out vehicle washing at theenclosure entrance at Works Site C.

Ongoing

Contract 10021 Surface runoff should be collected and discharged properly to

prevent flowing into public areaOngoing

2 The contractor should cover the air compressor by acoustic blanketentirely according to EP’s requirement.

3 Drip trap should be provided for chemical containers. Completed

The respective contractors have followed most of concerned items raised during theinspections for rectification in a responsible manner.

11.2 Other Notable Events

IEC Site Inspections

The IEC conducted site inspections for Works Areas on 18 and 12 September 2012 forContract 1001 and 1002 respectively. Some observations including improving effluent

23

control measures, enhancing noise and dust suppression measures were noted during thesite inspections and the respective Contractors had followed up the issues as identified inthe site inspections in a responsible manner.

EPD Inspection

EPD conducted inspection for contract 1002 on 14 September 2012 for the noisemitigation measures and site water discharge condition. EPD reminded the contractor tospeed up the installation of noise enclosure at Wan Hoi Street and provide sufficient sitewater treatment facilities if required.

12 FUTURE KEY ISSUES

12.1 Key Issues for the Coming Month

Future key issues envisaged in the coming month include the followings: Noise impact from operating equipment from site construction activities, e.g. pile/

sheet piling and rock breaking works; Fugitive dust impact from cement mixing activities and rock breaking works; Effluent discharge generated from various construction works; Tree protection.

12.2 Effectiveness and Efficiency of Mitigation Measures

Based on the environmental monitoring results of the reporting period, the effectivenessand efficiency of the mitigation measures implemented were found to be satisfactory. Therespective contractors were reminded to carry out their future construction activities tocomply with the requirements of the EP and the relevant contract requirements.

13 CONCLUSIONS

The Report presents the results of EM&A works and the impact monitoring for theconstruction works undertaken during the period of September 2012. The majorconstruction activities in the reporting period included utility and drainage diversions,temporary road & traffic diversion, piling works, bulk excavation, shaft and aditexcavation, soil nailing and ground improvement works.

No exceedance on noise and dust monitoring was recorded.

One invalid environmental complaints on dark smoke emission was referred by EPD andno valid complaint was received.

No notification of summon and prosecution were received in the reporting period.

Regular site inspections led by the Engineer’s Representative and anticipated by therepresentatives from ET and the respective Contractors’ Team were conducted on aweekly basis to monitor the implementation of environmental pollution control andmitigation measures for the Project. No non-conformance to the environmentalrequirements was identified by the Environmental Team in the reporting period. Theperformances of the respective contractors on site environmental management werefound in a responsible manner in this reporting period.

24

It is concluded from the environmental monitoring and audit works for the Kwun TongLine Extension Project were undertaken in a responsible manner. The environmentalprotection and pollution control measures provided by respective contractors of Contract1001 and 1002 were generally acceptable apart from some minor irregularities whichwere rectified timely by the respective civil works contractors.
