10.1
The following
summarizes the environmental monitoring and audit programmes for the
construction and operation of the concrete batching plant.
Air
10.2
Baseline
Monitoring: The 1-hour and 24-hou TSP samples from the baseline report of “Infrastructural
Works” for the Proposed Development at Telegraph Bay” are applicable
10.3
Impact Monitoring
(Construction and Operation Phases): During the construction of the stage 1
concrete batching plant and the first month of the full operation of stage 2
concrete batching plant, the monitoring frequency for 24-hour TSP obtained at
No.60 Sasson Road and Upper Kong Sin Wan Tsuen stations should be increased. It
is suggested to perform monitoring twice in every six days. For 1-hour TSP
monitoring, the monitoring frequency shall be increased to at least 4 times in
every 6 days. The impact monitoring data will then be compared with the air
quality criteria and the action as set out in the Event/Action Plan. Any
appropriate mitigation measures should then be implemented if exceedance of the
air quality criteria is recorded.
10.4
In case that there
is no exceedance due to the full operation of stage 2 concrete batching plant,
the monitoring frequency shall be returned to normal. Therefore, the routine
one 24-hour and three 1-hour TSP samples should be obtained from all stations
once six days, with 1-hour samples being collected when the worst dust impacts
occurs.
10.5
Apart from the
above two stations, continuous real time reporting of the air quality data on
two agreed existing monitoring locations (Baguio Villa and Pui Ying Secondary
School) are proposed so that a close look on the environment can be done.
Noise
10.6
Baseline
Monitoring:. The data from the baseline report of “Infrastructural Works for
the Proposed Development at Telegraph Bay” are applicable
Impact Monitoring
(Construction and Operation Phases): Continuous real time reporting of the
noise data on three current and one agreed existing monitoring locations are
proposed so that a close look on the environment can be done.
Water
10.7
During the
construction phase, if uncontrolled, contaminated surface runoff from the
construction site can flow into the harbour.
10.8
Baseline
monitoring: The data from the baseline report of “Infrastructural Works.for the
Proposed Development at Telegraph Bay” are applicable.
10.9
Impact Monitoring
(Construction): Since no marine construction, auditing works (such as checking
of perimeter channel, stream course, surface run-off and pre-treatment
facilities, etc) should be carried out.
10.10
During the
operation phase, no wastewater will be discharge outside the boundary of the
plant, there will not be any potential water quality impact. As that of
construction phase, auditing works should be carried out.
Waste
10.11
The contractor
will be responsible for waste control within the site as well as minimizing the
volume of waste generated. The contractor should comply with all the mitigation
measures as suggested in the EIA. Regular inspections carried out by the
environmental team will be required in order to check the contractor’s
compliance with the relevant specifications.
