the whole Reporting Period, water sampling was unable to carry out at WM2B and WM2B-C due to shallow
water (water depth under 150mm)
Action and Limit (A/L) Levels exceedance
ES04
In the Reporting Period, no construction noise exceedance
and valid noise complaint was recorded. For air quality
monitoring, one (1) Limit Level exceedance of 24-hour TSP was recorded. For water quality monitoring, a total of four (4) Limit Level exceedances were recorded under the Project. The summary of exceedance in the
Reporting Period is shown below.

ES05
Investigation report
for the 24-hour TSP monitoring was completed by ET. Investigation results
revealed that the Contractor had properly implemented dust mitigation measures
such covering of the stockpile and providing water spraying for dusty haul road
and dusty area. Since Joss paper burning
was suspected to be conducted during period of sampling, which affecting the monitoring
result, it was conducted that the exceedance was not caused by the works under
the Project.
ES06
Investigation
Report for all water quality exceedances was completed by ET. Investigation results revealed that the
Contractor had properly implemented water quality mitigation measures such as
covering the expose area with tarpaulin sheet and providing bunds align the
watercourse. It was concluded
that all the exceedances were not related to the works under the Project. Nevertheless,
the Contractor was reminded to fully implement the water
quality mitigation measure
throughout the constriction phase as far as practicable.

Site Inspection
ES10
In this Reporting Period, joint site inspection to evaluate the site

2018.
No non-compliance was noted during the site inspection.
ES11

inspection to evaluate the site environmental performance at Contract
SS C505 has been carried out by the RE, ET and the Contractor on 7, 14, 21 and 28
February 2018 in which IEC joined the site inspection on 21
February 2018. No non-compliance was noted during the site
inspection.
Future Key Issues
ES16
During dry season, special attention
should be paid on the potential construction dust impact since most of the construction sites are adjacent
to villages. The Contractor should fully implement the construction dust
mitigation measures as appropriately.
ES17
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.
ES18
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.
ES19
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.
