On 3 May 2013, Mott MacDonald Hong Kong Limited (MMHK) was
commissioned by the Drainage Services Department (DSD) under Agreement No. SP
05/2012 to undertake the Independent Checker (IC) services for the Sewerage
Works at Pik Shui Sun Tsuen
(The Project).
The
Environmental Permit (EP) No.
EP- 435/2011 for the “Sewerage Works at Pik Shui Sun Tsuen” was granted by the Environmental Protection
Department (EPD) on 20 December 2011. The construction works was carried out
Welcome Construction Co Ltd. (the Contractor), commenced on 26 August
2013.
In accordance with Section 5.1 and 5.3 of the Brief for
the Project and Condition 2.2 of the EP, a Monthly Environmental Audit Report shall
be prepared and submitted at monthly intervals to confirm in writing the full
implementation of the mitigation measures recommended in the Project Profile
(PP) (Register No. PP- 454/ 2011) during and upon completion
of the construction works.
When construction of the sewerage works at Pik Shui Sun Tsuen commenced,
objections from the local residents were encountered. Therefore, the sewerage
works were temporarily suspended. DSD arranged meetings with the local
residents and tried to resolve the objections. However, there were still
majority amongst the local residents showing their objections to the proposed
works in a meeting held on 18 January 2014. In March 2014, DSD and the client
office SIG of EPD decided to curtail the proposed sewerage works at Pik Shui Sun Tsuen from the
construction contract.
Regarding the sewerage work on University Road, some
sewer alignments were revised subject to actual condition. Therefore, DSD
submitted the application for variation of environmental permit for the sewerage
works at Pik Shui Sun Tsuen
to EPD on 16 July 2014 and the amended Environmental Permit (No. EP-435/2011/A)
was issued by EPD to DSD on 29 July 2014.
This is the 31th Monthly Environmental Audit
Report covering the period from 1 June 2016 and 30 July 2016 (the reporting
month).
The
construction work programme of the Project is provided in Appendix
A. A layout plan of the Project is provided in Figure 1.1.

Trenchless
excavation for pipe laying works at the verge of the footpath of University
Road.
The organisation chart and lines of
communication with respect to the on-site environmental management structure
together with the contact information of the key personnel are shown in Appendix
B.
The environmental site audit was
conducted on 23 June 2016 during this reporting month. The checklist of implementation status of the
environmental mitigation measures is provided in Appendix
C.
The
environmental site audit was conducted on 23 June 2016 during this reporting
month. All observations have been recorded in the site inspection checklist and
passed to the Contractor together with the appropriate recommended mitigation
measures where necessary. The key observations from site inspection and
associated recommendations are summarized in in Table 2-1.

The major site
works scheduled to be commissioned in the coming month include:
¡ Trenchless excavation for pipe laying works
at the verge of the footpath of University Road
Key issues to be
considered in the coming month include:
¡ Generation of dust from construction and
demolition works;
¡ Noise impact from operating equipment and
machinery on-site;
¡ Generation of site surface runoffs and
wastewater from activities on-site;
¡ Management of stockpiles and slopes,
particularly on rainy days;
¡ Sorting, recycling, storage and disposal of
general refuse and construction waste; and
¡ Management of chemicals and avoidance of oil
spillage on-site.
Site audit was conducted on 23 June 2016. Recommendations on remedial
actions were given to the Contractors for the deficiencies identified during
the site audit.
No complaint, notification of summons and prosecution was received in
the reporting month.
The Contractor was reminded to maintain noise, air quality, water
quality and waste management mitigation measures and also continuously implements
all environmental mitigation measures in accordance with the PP.
