Reporting Change

ES08 In the Reporting Period, EPD has approved the revised EM&A Programme (Rev.7) which included the proposal for not necessary to perform noise measurement during restricted hours periods. Therefore, noise measurement during restricted hours periods will be ceased on 7 April 2017 in accordance with the updated EM&A Programme (Rev. 07) (Section 3.1.5) (EPD ref.: ( ) in EP2/N7/A/52 Ax(1) Pt.20 dated 7 April 2017)

ES09 Moreover, EPD has approved the revised EM&A Programme (Rev.7) which proposed that (1) if the measured water depth of the monitoring station is lower than 150 mm, alternative location based on the criteria were selected to perform water monitoring; and (2) If no suitable alternative location could be found within 15m far from the original location, the sampling at that location will be cancelled since sampling at too far from the designated location could not make a representative sample in accordance with the updated EM&A Programme (Rev. 07) (Section 4.1.4) (EPD ref.: ( ) in EP2/N7/A/52 Ax(1) Pt.20 dated 7 April 2017)

Site Inspection

ES10 In this Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 2 has been carried out by the RE, IEC, ET and the Contractor on 7, 12, 21 and 28 April 2017. No non-compliance was noted during the site inspection.

ES11 In the Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 3 has been carried out by the RE, IEC, ET and the Contractor on 3, 10, 19 and 24 April 2017. No non-compliance was noted during the site inspection.

Future Key Issues

ES15 During wet season, preventive measures for muddy water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma Wat Channel, Ping Yuen River, Kwan Tei River or public area should be properly maintained. The Contractors should paid special attention on water quality mitigation measures and fully implement according ISEMM of the EM&A Manual, in particular for working areas near Ma Wat Channel and Ping Yuen River.

ES16 In addition, all effluent discharge shall be ensure to fulfill Technical Memorandum of Effluent Discharged into Drainage and Sewerage Systems, inland and Coastal Waters criteria or discharge permits stipulation.

ES17 Construction noise would be a key environmental issue during construction work of the Project. Noise mitigation measures such as using quiet plants should be implemented in accordance with the EM&A requirement.

ES18 Since most of construction sites under the Project are located adjacent to villages, the Contractors should fully implement air quality mitigation measures to reduce construction dust emission.
