Project
information
The
Organic Resources Recovery Centre (ORRC) 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 ORRC (Contract No. EP/SP/61/10 Organic Resources
Recovery Centre Organic Resources Recovery Centre (Phase I)) 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 December 2018.

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 during the
construction phase.
According to the EM&A Manual and EP requirement,
odour monitoring is required during the commissioning phase.
The odour patrols shall be conducted by an odour
patrol team. The odour patrol team will patrol and sniff along an odour patrol
route at the site boundary. The implementation of the odour patrol shall be
subject to the prevailing weather forecast condition and no odour patrol should
be carried out during rainy day. The odour patrol team should be comprised of
at least two independent trained personnel / competent persons, who should pass
a set of screening tests.
During August 2018, air samples were collected from
the outlet of the Centralised Air Pollution Control (CAPC) unit by ALS for
measurement of the Odour Intensity by olfactometry analysis at the laboratory.
According to the EM&A Manual and EP requirements, it is considered an
exceedance if the odour level is more than 220 OU/Nm3. During this reporting
period, the odour level of the odour samples collected from the CAPC unit have
exceeded the odour limits stated in Table 2.2 of the EM&A Manual. The
monitoring results are shown in Annex
H.
Investigation
of the exceedances has been conducted.
The investigation report is shown in Annex I.
During September 2018, odour patrol were conducted by representatives of the Contractor, the
ER and Employer (EPD Project Team) on 3, 5, 7, 10, 12, 14, 17, 19, 21, 24, 26
and 28 September 2018. The Independent Odour Patrol Team, ALS Technichem (HK) Pty Ltd (ALS), has
also joined the odour patrol on 10 and 28 September 2018. According
to the EM&A Manual and EP requirement, it is considered an exceedance if the odour
intensity recorded by the panellists is Level 2 or above. During this reporting period, no Level 2
Odour Intensity was recorded. The
odour patrol results are shown in Annex H.

26, 29 and 31 October 2018. The Independent Odour Patrol Team, ALS Technichem (HK) Pty Ltd (ALS), has
also joined the odour patrol on 26 October 2018.
According to the EM&A Manual and EP requirement, it is considered an exceedance if the odour
intensity recorded by the panellists is Level 2 or above. During this reporting period, no Level 2
Odour Intensity was recorded. The
odour patrol results are shown in Annex H.
On
5, 12, 19 and 26 October 2018, air samples were also collected from the outlet
of the Centralised Air Pollution Control (CAPC) unit by ALS for measurement of
the Odour Intensity by olfactometry analysis at the laboratory. According
to the EM&A Manual and EP requirements, it is considered an exceedance if the odour level is
more than 220 OU/Nm3. On
5, 12, 19 and 26 October 2018, the odour level of the odour samples collected
from the CAPC unit have exceeded the odour limits stated in Table 2.2 of the
EM&A Manual. The monitoring results
are shown in Annex
H.
Investigation
of the exceedances has been conducted.

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, 843.41 tonnes of inert C&D material were generated from
the Project, of which 325.00 tonnes were reused in this Contract and the
remaining 518.41 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

from 1 September 2018 to 30 November 2018 in accordance with EM&A Manual
and requirements of EP (FEP-01/395/2010/C).
No air quality, noise and water quality monitoring is
required during the construction phase.
Odour patrol and monitoring are required during the
commissioning phase. No exceedance
of odour intensity limit for all odour patrol events. Air samples were also collected at the
CAPC unit for olfactometry analysis at the laboratory on 31 August 2018, 5, 12, 19 and 26 October 2018 and 1, 5 and 23 November 2018. The result are
shown in Annex H. The odour level of the samples collected
on 31 August 2018, 5, 12,
19 and 26 October 2018 and 1
and 5 November 2018 have exceeded the odour limit. An investigation of the cause of the
exceedance has been carried out.
The investigation report was shown in Annex I.
Bi-weekly
landscape and visual monitoring was conducted in
this quarterly period. Most of the
necessary landscape and visual mitigation measures recommended in the EIA
Report were implemented by the Contractor.
Follow-up actions would be implemented by the Contractor to improve
protection measures on the retained or to-be transplanted trees.
No
non-compliance event was recorded during the reporting period.
One
complaint related to odour and no summons/prosecution was received during the
reporting period. The investigation
of the complaint has been carried out. The investigation report was shown in Annex
J.
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.
