Site Inspection

ES08 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 5, 12, 19 and 26 May 2017. No non-compliance was noted during the site inspection.

ES09 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 2, 8, 17, 22 and 29 May 2017. No non-compliance was noted during the site inspection.

ES10 For Contract 4, there were only minor construction activities, such as preparation work for E&M installation, carried out on the 1^st week of May 2017, therefore, the site inspection was commenced on the 2^nd week of May 2017. In the Reporting, joint site inspection for Contract 4 to evaluate the site environmental performance has been carried out by the RE, ET and the Contractor on 11, 18 and 26 May 2017 in which IEC joined the site inspection on 26 May 2017.

Future Key Issues

ES14 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.

ES15 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.

ES16 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.

ES17 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.
