Allied Environmental Consultants Limited
(AEC) has been appointed to conduct an environmental monitoring and audit
(EM&A) program for the Joint User Complex and Wholesale
Fish Market (WFM) at Area 44, Tuen Mun.
The construction works
were commenced on 31st July 2008 while major construction works of
the Project were substantially completed in September 2010 and handover works
were completed in November 2010, thus the EM&A programme
for construction phase was terminated effective from
23rd December 2010.
The operation of the WFM
was commenced on 23rd December 2010. This report is
the fourteenth and last quarterly
EM&A report, which detailed the
environmental monitoring and audit results recorded for operational phase during the period from 1st November
2011 to 31st December 2011.
Impact environmental monitoring for the Joint User Complex and Wholesale Fish Market at Area
44, Tuen Mun has
been carried out at Yuet Wu
Villa. Odour patrol and noise monitoring were conducted within the period
of 0300-0630
hours. The odour intensity ratings in the
reporting period were 1-No Odour. The minimum
and maximum average noise level measured at Yuet Wu
Villa was 50.9dB(A) Leq(5min) and 56.6dB(A) Leq(5min) respectively.
Based on the odour patrol results, the odour patrol
complied with the environmental requirements in EM&A Manual. The measured noise monitoring results were higher than the predicted
noise levels due to the increment of noise level from ambient background noise
levels.
In the reporting period, no
non-compliance,
complaint, inspection notice,
notification of summons or prosecution was received.
There was no major change in the operation of WFM.
Monitoring works had been conducted for 12 months of
the operational of the Wholesale Fish Market as stated in EM&A Manual and
the approved Environmental Permit EP-296/2007. The EM&A requirements were
fulfilled and the completion of EM&A programme
shall be notified to the EPD. The
operation phase EM&A programme was completed and
no further works should be carried out in future.
A Joint User
Complex and Wholesale Fish Market (WFM Complex) at Area 44 in Tuen Mun is designed and built by
Architectural Services Department on behalf of Agriculture, Fisheries and
Conservation Department, Marine Department, Home Affairs Department, and Food
and Environmental Hygiene Department of the Hong Kong SAR. The WFM Complex is
to provide a permanent site for the relocation of the existing temporary
wholesale fish market at Tuen Mun
Area 27 and to accommodate a community hall, a dragon boat racing spectator
stand, and other community facilities for public use. The development is a 3-storey complex to accommodate a
wholesale fish market, a public toilet, a refuse collection point and a marine
refuse collection point at the ground floor, a community hall on the first
floor, and a dragon boat race spectator stand with landscaped deck on roof level.
The
Wholesale Fish Market is categorized as a designated project under the
Environmental Impact Assessment Ordinance (EIAO) and therefore a detailed
Environmental Impact Assessment (EIA-085/2002) has been conducted in year 2002
and an Environmental Permit (EP-296/2007) was issued by Environmental
Protection Department in December 2007. The construction works were commenced on 31st July 2008.
Major construction
works of the Project were substantially completed in September 2010 and
handover works were completed in November 2010. The EM&A programme
of construction phase was
terminated and the EM&A programme of operational phase was commenced effective from
23rd December 2010.
The subject site is
located at Castle Peak Bay of Tuen Mun given in Figure 1. The subject
site is bounded to the north by a future local open space presently used as a
temporary car park, to the east by Castle Peak Bay typhoon shelter, to the
south by a future lorry park and to the west by Wu Shan Road. Yuet Wu Villa being the nearest residential establishment
is located at around 85m from the site boundary. Key personnel and contact
particulars are summarized in Table 1.

Air Sensitive Receivers (ASRs) within 500m
include Yuet Wu Villa, lawn bowling field, tennis
court, which are less than 100m away from the subject site. Tuen
Mun Wu Hong Clinic is located to the west at about
100m to the site boundary. Two secondary schools, Ka Chi Secondary School and
South Tuen Mun Government
Secondary School, are approximately 300m to the south of the site boundary.
Noise Sensitive Receivers (NSRs) within
300m are Yuet Wu Villa, Siu Hei
Court, Yan Chai Hospital Low Chan Chor Si Primary
School and Wu King Estate. The nearest NSR will be Block 15 of Yuet Wu Villa.
For regular
impact monitoring, odour patrol shall be carried out on a regular basis during
the first year of operation. Odour patrol shall be carried out once a week
during the first three months of operation of the WFM. The odour patrol
frequency shall be reviewed afterwards.
According to the
approved EM&A Manual, the Action and Limit Levels for operational phase
odour patrol are summarized in Table 2.

Should non-compliance of the above Action and Limit levels occurs, the Fish Marketing Organization (FMO) shall undertake corresponding in accordance with the Event/Action Plan given in
the EM&A Manual.
For noise
monitoring, the operational noise level shall be measured weekly in terms of
the A-weighted equivalent continuous sound pressure level (Leq).
Leq(5min) shall be used
as monitoring parameter for the period from 0300 to 0630 hours. Each set of
measurement shall include at least 3 consecutive Leq(5min) results. As supplementary information for data auditing, statistical
results such as L10(5min) and L90(5min) shall also be contained for reference.
Additional noise
monitoring shall not be given for marine traffic noise. With consideration given to the selected
access route, which represent the worst-scenarios in terms of distance to
nearby receivers, the highest marine traffic noise levels at nearby sensitive
receivers are found to be below the prevailing background noise level they are
currently exposed to. The operation of the proposed WFM is not expected to
generate additional marine traffic noise within the typhoon shelter and will
not cause any deterioration to the existing noise climate in the vicinity of
the typhoon shelter.
From baseline monitoring results, the Action and Limit Levels for operational phase noise monitoring are
summarized in Table 3.

Odour patrol and noise monitoring were conducted
around Yuet Wu Villa and at Block 15, Yuet Wu Villa. Appendix A
displayed the detail schedule of the odour patrol and noise monitoring. The
location plan of odour patrol and sniffing locations
are shown in Figure
2. Noise monitoring was conducted at 1.2m above ground level in front of
the residential block and at the junction of Wu Sau
Street and Wu On Street as given in Figure 3. Due
to thunderstorm, the weekly monitoring on 9th November 2011 was
postponed to 11th November 2011.
Results of
operational phase odour patrol and noise monitoring are summarized in Appendix B and
Appendix C
respectively. In the reporting period, the odour
intensity ratings were 1-No Odour. The minimum and maximum average
noise level measured at Yuet Wu Villa was 50.9dB(A) Leq(5min) and 56.6dB(A) Leq(5min) respectively.
The measured monitoring results were higher than
the predicted noise levels due to the increment of noise level from ambient
background noise levels.
6.
IMPLEMENTATION OF MITIGATION MEASURES
In the operational phase, the solid and
liquid waste management is not applicable. The relevant parties have
implemented odour and noise mitigation measures which
shall include, but not limited to the following:
l The WFM Complex (including the parking area)
shall be enclosed to reduce the odour nuisance to the
nearby residents;
l Contract specifications on the sound power
level of mechanical ventilation system shall be followed;
l Off-route lorries shall not pass along the Wu
Shan Road outside Yuet Wu Villa;
l Lorries queuing and vessel’s horning shall be
controlled by WFM management and AFCD.
All environmental mitigation measures for operational stages stated in approved EIA Report,
EM&A Manual and Environmental Permit was carried out throughout the whole operational period as shown in Appendix D. The environmental
mitigation measures undertaken were considered adequate. There was no major change in the operation
of WFM and no additional environmental mitigation measures shall be given. In the coming month, the odour
patrol frequency shall be reviewed.
