Water Quality Parameters
4.3.2. Monitoring
of dissolved oxygen (DO), turbidity and suspended solids (SS) shall be carried
out at WSD flushing water intakes and cooling water intakes. DO and Turbidity
are measured in-situ while SS is determined in laboratory.
4.3.3. In
association with the water quality parameters, other relevant data shall also

Sampling Procedures and
Monitoring Equipment
4.3.4. The
interval between two sets of monitoring should not be less than 36 hours except
where there are exceedances of Action and/or Limit Levels, in which case the
monitoring frequency will be increased. Table 4.4 shows the

re-calibrated at 3 monthly intervals throughout all stages of the water quality
monitoring. Responses of sensors and electrodes should be checked with
certified standard solutions before each use. Wet bulb calibration for a DO
meter shall be carried out before measurement at each monitoring location.
4.3.15. For the on site calibration

7.0.1. This
section addresses the relevant cumulative construction impact due to the
concurrent activities of the current projects including the Central Reclamation
Phase III (CRIII), Wan Chai Development Phase II (WDII), Central-WanChai Bypass
(CWB), Island Eastern Corridor Link projects (IECL) and Wan Chai Development
Phase II – Central – Wan Chai Bypass at Wan Chai East (CWB Tunnel).
7.0.2. According to the Final EM&A report of Central
Reclamation Phase III (CRIII) for Contract HK 12/02, the major construction
activities were completed by end of January 2014 and no construction activities
were undertaken thereafter and the water quality monitoring was completed in October
2011. As such, it is considered that
there were no cumulative construction impact due to the concurrent activities
of the current projects with the Central Reclamation Phase III (CRIII)
undertaken by contractor HK12/02 in the reporting month.
7.0.3. According to the
construction programme of Central-Wanchai Bypass at Wanchai West at the Central
Reclamation Phase III area, no works was conducted in March 2020 reporting
period. In view of the above, the cumulative construction impact due to the
Central Reclamation Phase III (CRIII) was not anticipated.
7.0.4.
According to the construction programme of Wan Chai Development Phase
II, Central-Wan Chai Bypass and Island Eastern Corridor Link projects, lighting
column installation works under Wan Chai Development Phase II was conducted at
Wan Chai. The major construction activities under Central-Wan Chai Bypass and
Island Eastern Corridor Link Projects were ventilation building ABWF works at
Central; road works, drainage improvement work, utility diversion works and landscape
works at Victoria Park; bridge noise enclosure installation works, road works,
drainage works, soft landscape works and ventilation building ABWF work at
North Point area in the reporting period. In addition, other non-Wan Chai
Development Phase II, Central-Wan Chai Bypass and Island Eastern Corridor Link
projects were observed undertaken at Wan Chai North and North Point area.
7.0.5. As relevant site
mitigation measures for air quality and construction noise were implemented, no
significant air quality impact and noise impact from construction activities
was concluded in the reporting period. Besides, no construction work was
conducted at EP-122 area in the reporting period. Thus, it is evaluated that
the cumulative construction impact from the concurrent projects including Wan
Chai Development Phase II (WDII), Central- WanChai Bypass (CWB), Island Eastern
Corridor Link projects (IECL) was insignificant.
8.1.1 As WDII RSS
confirmation of construction works completion at CRIII area on 21 October 2019
