Project information
The Organic Waste Treatment Facilities
(OWTF) Phase I development (hereinafter referred to as “the Project’) is to
design, construct and operate a biological treatment facility with a capacity
of about 200 tonnes per day and convert source-separated organic waste from
commercial and industrial sectors (mostly food waste) into compost and biogas
through proven biological treatment technologies.
The environmental
acceptability of the construction and operation of the Project had been
confirmed by findings of the associated Environmental Impact Assessment (EIA)
Study completed in 2009. The
Director of Environmental Protection approved this EIA Report under the
Environmental Impact Assessment Ordinance (EIAO) (Cap. 499) in February 2010
(Register No.: AEIAR-149/2010) (hereafter referred to as the approved EIA Report). Subsequent Report on Re-assessment on
Environmental Implications and Report on Re-assessment on Hazard to Life
Implications were completed in 2013, respectively.
An
Environmental Permit (EP) (No. EP-395/2010) was issued by the Environmental Protection Department
(EPD) to the EPD, the Permit Holder, on 21 June 2010 and varied on 18 March
2013 (No. EP-395/2010/A) and 21 May 2013 (No. EP-395/2010/B),
respectively. The Design
Build and Operate Contract for the OWTF (Contract No. EP/SP/61/10 Organic Waste
Treatment Facilities Phase I (the Contract)) was awarded to SITA Waste Services
Limited, ATAL Engineering Limited and Ros-Roca, Sociedad Anonima jointly trading
as the OSCAR Bioenergy Joint Venture (OSCAR or the Contractor). A Further EP (No.
FEP-01/395/2010/B) was issued by the EPD to the OSCAR
on 16 February 2015.
Under
the requirements of Condition 5 of the EP (No. FEP-01/395/2010/B), an
Environmental Monitoring and Audit (EM&A) programme as set out in the
Agreement No. CE7/2008 (EP) EM&A Manual (hereinafter referred to as
EM&A Manual) is required to be implemented. ERM-Hong Kong, Ltd (ERM) has been
appointed by OSCAR as the Environmental Team (ET) to undertake the EM&A programme for the Contract.
The construction works commenced on 21 May 2015 and
are scheduled for completion by April 2017.
The
Project Site is located at Siu Ho Wan in North Lantau with an area of about 2
hectares. The
layout of the Project Site is illustrated in Annex A.

Waste Management
Wastes
generated from this Project include inert construction and demolition (C&D)
materials (public fill) and non-inert C&D materials (construction
waste). Construction waste
comprises general refuse, metals and paper/cardboard packaging materials. Metals generated from the Project are
also grouped into construction waste as the materials were not disposed of with
others at public fill. Reference
has been made to the Monthly Summary Waste Flow Table prepared by the Contractor
(see Annex F).
With reference to the relevant handling records and trip tickets of this
Project, the quantities of different types of waste generated in the reporting
month are summarised in Table 5.1.

Environmental Inspections
Joint site
inspections were conducted by representatives of the Contractor, the ER, IC and
the ET on 28 May, and 5, 12, 17 and 26 June 2015. The IEC was also
present at the joint inspection on 17 June 2015. Follow-up actions resulting from the last
site inspections were taken as reported by the Contractor and their results
were observed in the site inspections conducted in the reporting period.
Major observations during the reporting period are
summarised as follows:
28 May 2015
·
The
discharge point is not yet covered properly. It is recommended to place sand bags
around the discharge point or cover the discharge point to avoid untreated
wastewater run-off.
·
The
sedimentation tank was observed to be full after raining and the untreated
water in the sedimentation tank was discharged onto the site without passing
through the WetSep for treatment. It is recommended to recirculate the
untreated water back to the sump pit and stop pumping water to the
sedimentation tank from sump pit when the WetSep is
shut down for emergency or maintenance purpose.
·
General
refuse and debris was observed within the tree protection zone of Trees T40,
T41 and T44. It is recommended to
clear general refuse near the trees (T40, 41 and T44) and provide toolbox talk
to all workers on tree protection measures.
·
The
tree trunk of Trees T40, T41 and T44 was observed to be tied too tight by
plastic strips. It is recommended
to loosen ropes and plastic strips and avoid tying around the trees.
·
No
protection zone was set up for trees T43 and T44 within the site. It is recommended to fence off the
identified trees to block the access to the identified trees.
·
Wire
was observed to be hanged on the branches of Tree T44. It is recommended to remove wires and
avoid hanging any materials on the tree.
5 June 2015
·
Pond
water is found in the tray under the chemical container. It is recommended to clear
the pond water regularly, especially after raining.
12 June 2015
·
Pond
water is found in some areas such as areas near vehicle washing facilities,
parking area, on tarpaulin sheets and in the U-channel. It is recommended to
clear the pond water regularly, especially after raining. Pond water is found
in the cop of an excavator. It is recommended to check if there is any pond
water regularly, especially after raining. It is also recommended to turn it
upside down to prevent pond water.
·
Pond
water is found in drip trays. It is recommended to clear the pond water
regularly, especially after raining.
·
Drip
tray is missing for some of the chemical containers. It is recommended to
provide drip tray under every chemical containers, even if the chemical are
recently arrived to avoid chemical leakage.
17 June 2015
·
A
single chemical container without a drip tray is found. It is recommended to
provide drip tray under every chemical containers, and to place the same type
of chemical in the same area.
·
Exposed
area is found to be dry and dusty. It is recommended to spray water regularly
to prevent dry and dusty situation.
26 June 2015
·
Soil
is found to be not completely covered by tarpaulin. It is recommended to fully
cover it to prevent dry and dusty situation.
·
Drip
tray is missing for some of the chemical containers. It is recommended to
provide drip tray under every chemical containers, even if the chemical are
recently arrived to avoid chemical leakage.
·
General
refuse is found in a tank. It is
recommended to provide general refuse point in AD Plant Tank area.
·
Pond
water is found in drip trays. It is
recommended to clear the pond water regularly, especially after raining
6.2
Landscape
and Visual Audit
In accordance with the EM&A Manual, bi-weekly
landscape and visual inspection is required to
ensure that the design, implementation and maintenance of landscape and visual
mitigation measures recommended in the EIA Report are fully achieved. An onsite inspection of the landscape and
visual mitigation measures was performed on 5 and 17 June 2015.
Follow-up actions resulting
from the last site inspections were taken as reported by the Contractor and
their results were observed in the site inspections conducted in the reporting
period.
It was confirmed that most
of the necessary
landscape and visual mitigation measures as summarised in Annex E were
implemented by the Contractor.
The major findings are summarised as follows:

Bi-weekly landscape and visual monitoring was
conducted in the reporting period.
Most of the necessary landscape and visual mitigation measures
recommended in the EIA Report were implemented by the Contractor. Follow-up actions are required by the
Contractor to improve protection of the retained or to-be transplanted trees.
No non-compliance event was recorded during the
