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.
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.
A summary of the major construction
activities undertaken in the reporting period is shown in Table 2.1. The locations of the construction activities
are shown in Annex

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.
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.
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.
