According to the information of the Contractor (China State Construction Engineering (HK) Ltd.),
ground investigation for site preparation work was carried out at the area near
Fui Sha Wai at Tai Hang of Tai Po on 19 December 2013.
The diesel-like smell was likely generated from the exhaust of drilling rig
during operation (Figure 1).
Upon the receipt of complaint
on 19 December 2013, the Contractor met the complainant to discuss for
improvement measures to be taken for the works on the same day (Figure 2). The
Contractor subsequently extended
the exhaust duct of the drilling rig to a higher position for achieving a
better gas dispersion and hence to reduce the impact to the public on 20 December 2013 (Figure 3).
The Contractor is willing to defer the operation time of the drilling
rig to later time in the morning to minimize nuisance caused to the public.
The noise and odour nuisance complaint is considered project-related.
The Contractor is advised to implement the mitigation measures as stated
in ¡°Recommended Mitigation Measures¡±.
- Site clearance;
- Ground investigation; and
- Tree felling and
transplantation.
-
Properly store and label oils and chemicals on site;
-
Chemical, chemical waste and waste management;
-
Collection of construction waste should be carried out regularly;
-
Properly maintain all drainage facilities and wheel washing
facilities on site;
-
Exposed slopes should be covered up properly if no temporary work
will be conducted;
-
Quieter powered mechanical equipment should be used;
-
Suppress dust generated from excavation activities and haul road
traffic; and
-
Tree protective measures for all retained trees should be well
maintained.
Air Quality Impact
l All vehicles should be washed to remove any dusty materials before leaving the site.
l Haul roads should be sufficiently dampened to minimize fugitive dust generation.
l Wheel washing facilities should be properly maintained to ensure properly functioning.
