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 twelfth quarterly
EM&A report, which detailed the
environmental monitoring and audit results recorded for operational phase during the period from 1st May 2011 to 31st
July 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 52.5dB(A)
Leq(5min) and 57.6dB(A) Leq(5min) respectively.
Based on the monitoring results, the odour patrol
complied with the environmental requirements in EM&A Manual. The measured 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.
In the coming month, monitoring works shall
persist as stated in EM&A Manual.
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 14th May 2011 and 27th
June 2011 was postponed to 15th May 2011 and 1st July
2011 respectively.
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 52.5dB(A) Leq(5min) and 57.6dB(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.
