the IEC/ENPO on 11 January 2017. According to the
investigation, the site environment of the working areas were found acceptable that
no mosquito was observed and cleanness of portable toilets were also found
acceptable but it will have some improvement. Hence, the complaint was found
non-related to Contract No. HY/2013/02. The complaint investigation report (Log No. 009) was provided in Appendix J.
During
January 2017, there was a complaint received by Environmental Protection Department from
a bus operator at the Hong Kong International Airport recently and referred to
the ENPO.
Then the ENPO forwarded the complaint by email to the R.E. (AECOM), the
Contractor (China Harbour) and the ET (ETS-Testconsult Ltd.) of Contract No.
HY/2013/02 at 12:17 on 09 January
2017.
The
complainant complained that the external bodies of buses
& vehicles were seriously stained by the heavy dusts and mud produced from
the construction sites onto the East Coast Road & Tung Fai Road, Airport
Road Interchange and Sky City Interchange.
The
above mentioned complaint follow-up inspection was performed by the Environmental Officer and the RE of Contract No. HY/2013/02 and EPD¡¦s senior
inspector Dionne Leung on 10 January 2017. The complaint investigation report (Log No. 010)
was issued by the ET of Contract No. HY/2013/02 and verified by the IEC/ENPO on
23 January 2017.
According to the investigation, no mud/slurry was observed

Mitigation measures under the item A2 and W2 of EMIS were implemented including
provide vehicle
washing facilities with high pressure water jet at vehicle exit point and the
area where vehicle washing takes place, the portion of road to construction
site of the vehicle entrance or exit was kept clear of dusty materials, all
vehicles and plant were cleaned before they leave the construction site, wheel
overflow was directed to silt removal facilities before being discharged, the
road section between the washing facilities and the exit point was hard paved
and reminders were provided at the wheel washing basin and exit to remind all
Contract(s) vehicles using the site exit for proper wheel washing etc. Besides, after received the last complaint from the EPD on 01 December
2016, the cleaning actions were reinforced such as providing one person at the
site entrance for cleaning up the mud/slurry, frequently checking the East Coast Road site entrance. Hence, the complaint was found

safety consideration and to avoid mixing of sediment between contracts, each
dumping date will be allocated to one Contract. The quantity of marine sediment
disposed on each date is from one Contract.
6.2.3.3 During dumping, HY/2013/02 is
responsible for transporting the marine sediment from his site area to the
barge by Land transportation. The estimated quantity of marine sediment in each
truck is confirmed by Resident Site Staff of each
Contract. The trip tickets for transportation and disposal of marine sediment
are collected and checked. Contract No. HY/2013/03 as the dumping permit holder
is responsible for reporting to EPD the quantity disposed of as the
condition stipulated in the dumping permit.
6.2.4 There was no marine sediment extracted from bored piling in this Contract disposed to allocated
dumping site via Contract
No. HY/2013/03 in this reporting
