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. Variation to both EPs No. EP-395/2010/B
and No. FEP-01/395/2010/B were made in December 2015. The latest EPs, No. EP-395/2010/C and No.
FEP-01/395/2010/C, were issued by the EPD on 21 December 2015.
Under the
requirements of Condition 5 of the EP (No. FEP-01/395/2010/C), 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
September 2017.

Environmental Monitoring Requirement, environmental Mitigation Measures
All the
relevant environmental mitigation measures listed in the EIA Report and
EM&A Manual are summarised in Annex
E.
According
to the EM&A Manual and EP requirement, no air quality, noise and water
quality monitoring is required.
Bi-weekly
landscape and visual audit is required to ensure that the design,
implementation and maintenance of landscape and visual mitigation measures
recommended in the EIA Report are fully achieved.

Implementation Status on Environmental Protection Requirements
The Contractor has implemented environmental mitigation
measures and requirements as stated in the approved EIA Report and EM&A
Manual. The implementation status
of the measures during the reporting period is summarised in Annex E.

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 in Table 5.1.

Notes:
(a) Inert
C&D materials (public fill) include bricks, concrete, building debris,
rubble and excavated spoil. In
total, 5,182.67 tonnes of inert C&D material were generated from
the Project, of which 1,432.60 tonnes were reused in this Contract and the
remaining 3,750.07 tonnes were disposed as public fill to Fill Banks at Tuen
Mun Area 38. The detailed waste flow is presented in Annex F.
(b) Non-inert
C&D materials (construction wastes) include metals, paper / cardboard
packaging waste, plastics and other wastes such as general refuse. Metals generated from the Project were
grouped into construction wastes as the materials were not disposed of with
others at the public fill.
(c) 49,140.00 kg of metals, 39,964.00 kg of papers/ cardboard packing and 6,510.00 kg of plastics were sent to recyclers for recycling during the
reporting period.
(d) Construction wastes other than metals, paper/cardboard packaging,
plastics and chemicals were disposed of at NENT Landfill by subcontractors.

Environmental Inspections
Thirteen
site inspections were conducted during the reporting period. There was no non-compliance recorded
during the site inspections.
Follow-up actions were undertaken as reported by the Contractor and
observed in the subsequent weekly site inspections conducted in the reporting
period.
December 2016
Joint
site inspections were conducted by the representatives of the Contractor, SOR
and the ET on 5, 12, 21 and 28 December 2016. The IEC was also present at the joint inspection on 21 December 2016.
January 2017
Joint
site inspections were conducted by the representatives of the Contractor, SOR
and the ET on 4, 9, 18 and 23 January 2017. The IEC was also present at the joint
inspection on 18 January 2017.
February 2017
Joint
site inspections were conducted by the representatives of the Contractor, SOR
and the ET on 1, 6, 15, 20 and 27 February 2017. The IEC was also present at the joint inspection on 15 February 2017.
Seven landscape and visual
monitoring site inspections were conducted during the reporting period. Follow-up actions needed to be
implemented were recommended to the Contractor and the status of the follow-up
actions was reviewed during the subsequent weekly site inspections. It was confirmed that most of the
necessary landscape and visual mitigation measures as summarised in Annex
E
were implemented by the Contractor.
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. The onsite inspection of the landscape and visual
mitigation measures has commenced since June
2015 during weekly site inspections.
December 2016
Bi-weekly site inspections were
conducted on 5 and 19 December 2016.
January 2017
Bi-weekly site inspections were
conducted on 3, 17 and 26 January
2017.
February 2017
Bi-weekly site inspections were
conducted on 6 and 20 February 2017.
Key
landscape and visual mitigation measures implemented in the reporting period
included:
·
Provide insect prevention
measures to the exposed root of retained tree to prevent potential damage due
to the exposure.
·
Provide the non-moisture
holding material around the trees to prevent potential damage.
·
Avoid placing machine near
the tree protection zone.
6.3
Effectiveness
of Mitigation Measures and Monitoring
The mitigation measures
recommended in the EIA report and required by the EP are considered effective
in minimizing environmental impacts.
The EM&A for the
Project was conducted as scheduled during the reporting period. No non-compliance events were observed
during site inspections and no
exceedances were recorded during this reporting period. The EM&A programme is
considered effective.

No non-compliance event was
recorded during the reporting period.
No complaint and
summons/prosecution was received during the reporting period.
The ET will keep track on
the EM&A programme to ensure compliance of environmental requirements and
the proper implementation of all necessary mitigation measures in the coming
periods.
