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.
Odour patrols 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 patrols on
10 and 28 September 2018. The officially
odour patrol results for 28 September 2018 from ALS are not yet available at
the time when this report was prepared.
The results will be presented in the next monthly EM&A report. According to the EM&A Manual
and EP requirements, 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 31 August 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 200 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 exceedance has been conducted. Odour
emitting activities, including wastewater treatment plant and ammonia stripping
plant (ASP) were operating on 31 August 2018.
No organic waste were being processed the time the odour samples were
being collected, due to pre-treatment line was stopped and only operated at mid
night. The CAPC system was operating
during the odour sampling. The
contractor reported that the active carbon (AC) filter and the venture scrubber
in Building 2 were operating. The wet
& chemical scrubbers were not operating at the time of the sampling as it
is still under testing and commissioning.
The exceedance could be due to saturation of the AC filter as an
increase of VOCs concentration was observed.
The contractor has
replaced all AC filter media in the last week of September 2018. To avoid saturation of the filter media, it
is recommended that the contractor should test the medium regularly or
indicator medium should be used to provide an indication of the condition of
the media.
On 28 September
2018, air samples were also collected from the outlet of the CAPC unit by ALS
for measurement of the odour level by olfactometry analysis at the
laboratory. The monitoring results are
not yet available at the time when this report was prepared. The results will be presented in the next
monthly EM&A report.
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
3, 11, 19 and 26 September 2018. The IEC was also present at the joint inspection on 19 September 2018.
Follow-up actions resulting from the last site inspections were
generally taken as reported by the Contractor.
Key observations
during the reporting period are summarised as follows:
3
September 2018
· Stagnant water was observed
on Building 1 roof and the Contractor was advised to remove the stagnant water to
prevent mosquito breeding.
11 September
2018
· No particular observation
during this reporting period.
19 September 2018
· The Contractor was reminded
to remove the waste in waste skip more frequently to avoid or minimise odour
and flies.
· Insufficient cleaning
inside the Building 1 and many flies were observed near Building 1. The Contractor was advised to enhance the
cleaning to improve the tidiness and hygiene of Building 1, and close the door
of Building 1 properly to prevent the flies (if any) from escaping from the
building. The Contractor should also
increase the frequency of pest control if excessive number of flies were found.
· Leakage of wastewater was
observed in Building 1, but the wastewater did not get to the surface
channel. The Contractor was advised to
enhance the prevention measures to avoid reoccurrence of such leakage and to
prevent the wastewater from getting to the surface channel.
26 September 2018
· A used carbon filter was
found on the ground near Building 2, and the Contractor was advised to remove
the carbon filter to avoid potential contamination of surface runoff in the
area if it rains.
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. On-site inspections of the landscape and
visual mitigation measures were performed on 3 and 17 September 2018.
It was confirmed that the
necessary landscape and visual mitigation measures as summarised in Annex E were generally implemented by the
Contractor. No specific observation
was found during site inspection on 3 September 2018.
During the 17 September inspection, three trees (labelled T35, T10425 and T10448) were
found felled down due to typhoon Mangkhtu on 16 September 2018, and they were
subsequently removed by the Contractor.
