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 April 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.

C&D materials (public fill) include bricks, concrete, building debris,
rubble and excavated spoil. In
total, 10,967.41 tonnes of inert C&D material were generated from
the Project, of which 75.28 tonnes were reused in this Contract and the
remaining 10,892.13 tonnes were disposed as public fill to Fill Banks
at Tuen Mun Area 38 and Tseung Kwan O Area 137. 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) 18,650.00 kg of metals, 120.00 kg of papers/ cardboard packing and 0.00 kg of plastics were sent to recyclers for recycling during the
reporting period.

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 I 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
2015
