Section 9: Conclusions
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.
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.

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.

Joint site
inspections were conducted by representatives of the Contractor, the ER, IC and
the ET on 1, 8, 17, 22 and 29 July 2016.
The IEC was also present at
the joint inspection on 17 August
2016. 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.
Key observations
during the reporting period are summarised as follows:
1 August 2016
· Chemical containers were observed to be without secondary containment in
Building 2 Area. The contractor should
provide drip trays to retain the chemicals in case of any leakage in accordance
with the COP.
8 August 2016
·
Chemical containers were
observed to be without secondary containment in Building 2 and AD Tank Area. The contractor should provide drip trays to
retain the chemicals in case of any leakage in accordance with the COP.
·
Tarpaulin covering the site
boundary near AD Tank Area is damaged. The contractor should replace the tarpaulin
completely covering the site boundary.
17 August 2016
·
General refuse was
scattered on floor without proper storage.
The contractor should provide sufficient enclosed bins near Building 2
area for workers on site.
22 August 2016
· Stagnant water was found in AD Tank and Building 2 area. The contractor was recommended to clear the
water to prevent mosquito breeding.
· Chemical containers were observed to be without secondary containment in
Building 2 Area. The contractor should
remove the used-up chemical containers and provide drip trays to retain the
chemicals in case of any leakage in accordance with the Code of Practice (COP).
29 August 2016
·
Stagnant
water was found in AD Tank and Building 2 area.
The contractor was recommended to clear the water to prevent mosquito
breeding.
·
Chemical
containers were observed to be without secondary containment in Building 2
Area. The contractor should remove the
used-up chemical containers and provide drip trays to retain the chemicals in
case of any leakage in accordance with the COP.
·
General
refuse wrapped by plastic bag was observed to be within and near Building 2
Area. The contractor was reminded to
provide sufficient enclosed bins and regular waste collection.
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. Onsite inspections of the landscape and
visual mitigation measures were performed on 8 and 22 August 2016.
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 the necessary landscape and visual mitigation measures as summarised in Annex E were generally implemented by the
Contractor. 13 labelled trees T3, T4,
T5, T6, T7, T8, T9, T26, T27, T28, T29, T30 and T34 were felled due to the irreversible
damage caused by Typhoon Nida on 2 August 2016.
No other specific observation was found during site inspection on 8 and
22 August 2016.
One non-compliance event of inappropriate wastewater
discharge was identified by EPD during the reporting period. The incident is under investigation. The investigation report will be attached in
the next Monthly EM&A report.
Works to be undertaken for the coming monitoring
period are summarised in Table 8.1.
