6.2
Advice on the Solid and
Liquid Waste Management Status
6.2.1
The Contractor registered as a chemical waste producer for the
Contract. Sufficient numbers of receptacles were available for general refuse
collection and sorting.
6.2.2
There was no excavated marine sediment generated in this reporting period. The excavated marine sediment was stored properly on
site during this reporting period until further instruction by the Engineer.
The disposal of excavated sediment as per EP-353/2009/K to be implemented subject
to confirmation.
6.2.3
Disposal of Marine
Sediment
6.2.3.1 For the marine
sediment disposal, after the acceptance of the review of the approved Sediment
Quality Report (SQR) for this Project under EPD letter dated 19 August 2015, an
approval to dispose the marine sediment extracted from bored piling for this
Project was then approved under memo from Secretary, Marine Fill Committee of
CEDD dated 20 August 2015 for the disposal of marine sediment extracted from
bored piling works. The disposal sites allocated to this Project are the Mud
Pit CMP2 of the Confined Marine Sediment Disposal Facility to the South of The
Brothers (or at the East of Sha Chau). As advised by CEDD in the memo dated 19
February 2016, from 00:00 on 22 March 2016 onward, the disposal space at CMP2
of the South of The Brothers is closed and all disposal of contaminated
sediment is to be carried out at CMP Vd to the East of Sha Chau (ESC). As a
practical means, the disposal operation is managed by one contractor who is
also responsible for applying dumping permit and its subsequent extension
applications from EPD. Contract No. HY/2013/03 has been assigned to coordinate
and arrange for disposal of extracted marine sediment from Contract No.
HY/2013/02, HY/2013/03 and HY/2013/04.
6.2.3.2 For the dumping
arrangement, the barge for disposal of marine sediment will moor at the
temporary loading and unloading at the east shore of the
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/
