4.5 Monitoring Methodology
Both 1-hr and
24-hr air quality monitoring (High Volume Sampler)
Instrumentation
High volume sampler, as HVS, (Greasby GMWS2310) complete
with appropriate sampling inlets were employed for both 1-hour and 24-hour TSP
monitoring. The sampler is composed of a motor, a filter holder, a flow
controller and a sampling inlet and its performance specification complies with
that required by USEPA standard Title 40, Code of Federation Regulations
Chapter 1 (Part 50).
Installation
The installation of HVS refers to the
requirement stated in EM&A Manual.
Operation/Analytical
Procedures
Operating/analytical
procedures for the operation of HVS are as below:
·
Prior to the commencement of the dust
sampling, the flow rate of the high volume sampler was properly set (between
·
For TSP sampling, fiberglass filters
(GA-55) were used.
·
The power supply was checked to ensure
the sampler worked properly.
·
On sampling, the sampler was operated 5
minutes to establish thermal equilibrium before placing any filter media at
designated air monitoring station.
·
The filter holding frame was then
removed by loosening the four nuts and carefully a weighted and conditioned
filter was centered with the stamped number upwards, on a supporting screen.
·
The filter was aligned on the screen so
that the gasket formed an air-tight seal on the outer edges of the filter. Then the filter holder frame was tightened to
the filter holder with swing bolts. The applied pressure should be sufficient
to avoid air leakage at the edges.
·
The programmable timer will be set for a
sampling month of 1 hour or 24
hours. Information was recorded on the
record sheet, which included the starting time, the weather condition and the
filter number (the initial weight of the filter paper can be found out by using
the filter number.).
·
After sampling, the filter was
transferred from the filter holder of the HVS to a sealed plastic bag and sent
to the laboratory for weighting. The
elapsed time was also recoded.
·
Before weighting, all filters were
equilibrated in a desiccator for 24 hour with the temperature of 25oC
+ 3oC and the relative humidity (RH) <50% +5%.
·
All measurement procedures in Section
2.3 of the EM&A Manual were followed during the reporting month.
Maintenance
& Calibration
·
HVS and their accessories should be
maintained in good working condition, such as replacing motor brushes routinely
and checking electrical wiring to ensure a continuous power supply.
·
HVS should be calibrated at bi-monthly
intervals.
Wind Data Monitoring
Wind data (wind speed and wind direction) were directly
extracted from Tseung Kwan O
Station of Hong Kong Observatory. All wind data during this reporting month are
shown in Appendix I E.

Monitoring Methodology and Equipment Used
For Location of the monitoring stations
Global Positing System (GPS)
A hand-held
digital GPS was used to identify the designated monitoring stations prior to
water sampling.
For Water Depth measurement
Echo Sounder
A portable,
battery-operated echo sounder was used for the determination of water depth at
each designated monitoring station.
For In-situ Water Quality
Measurement
All in-situ
monitoring instruments were checked, calibrated and certified by a laboratory
accredited under HOKLAS or any other international accreditation scheme before
use, and subsequently re-calibrated at 3 monthly intervals or sometimes longer
throughout all stages of the water quality monitoring.
Dissolved Oxygen, Salinity and Temperature Measuring Equipment
A portable, weatherproof dissolved oxygen
& salinity measuring instrument, which complete with
cable, sensor and DC power source (e.g. YSI 85 or equivalent) was used for measuring:
·
a dissolved oxygen level in the range of 0-20 mg/L and 0-200 %
saturation;
·
a salinity in range 0-40 ppt; and
·
a temperature of 0-45 degree Celsius
A membrane electrode with
automatic temperature compensation complete with a cable
was installed.
Turbidity
Measurement Instrument
A portable and weatherproof turbidity meter
(HACH model 2100Q) was used during impact monitoring. It has a photoelectric sensor
capable of measuring turbidity between 0-1000 NTU. Response of the sensor was
checked with certified standard Turbidity solutions before the start of
measurement.
For Water
Sampling and Sample Analysis
In-situ monitoring was carried out at three
depths: 1 meter below water surface, at mid-depth and 1 meter above the seabed.
If the water depth is less than
Water Sampler
A water sampler comprising a transparent
PVC cylinder, with a capacity of not less than 2 liters, was lowered into the
water body at the predetermined depth. The both opening ends of the sampler
were then closed accordingly by dead weight and water samples were collected.
Water Container
The sample
container, made by high-density polythene, was rinsed with a portion of the
water sample. The water sample was then transferred to the container, labelled
with a unique sample ID and sealed with a screw cap. The water samples were
stored in a cool box maintained at 4oC. The water samples were then
delivered to a local HOKLAS-accredited laboratory (Environmental Laboratory, ETS-Testconsult
Ltd, HOKLAS Registration No. 022) on the same day for analysis.
The summary of testing method of testing

In-situ measurement
All in-situ
monitoring instruments were checked, calibrated and certified by a laboratory
accredited under HOKLAS or any other international accreditation scheme before
use. Responses of sensors and electrodes were checked with certified standard
solutions before each use. Wet bulb calibration for a DO meter was carried out
before the start of measurement.
At each measurement/sampling depth, two
consecutive measurements of dissolved oxygen (DO), dissolved oxygen saturation
(DOS), turbidity and salinity were taken. For turbidity measurement, the sample
was collected by using sampler and then transferred to the cell. The reading of
turbidity of the sample was directly recorded from the
Turbidimeter
(HACH 2100Q) after inserting the cell
to the Turbidimeter. For DO, DOS and Salinity, duplicate measurements were
performed by dropping the calibrated probes of the corresponding monitoring
equipments to the designated depths of the water column and taking readings
after stabilized. The duplicate measurements were averaged if the difference
was not greater than 25%. If the difference is greater than 25%,
repeat measurement will be required.
Table 6.5 shows
the equipment used for in-situ monitoring of water quality. The calibration
certificates are attached in Appendix I D1.

The observations for the monitoring works were recorded and summarized as follows:
Air Quality Monitoring
§ The monitoring
team recorded the observations around the monitoring stations within and
outside of the site.
§ The monitoring
team recorded the temperature, air pressure and general weather condition on
the monitoring day.
Noise Monitoring
§ The monitoring
team recorded the observations around the monitoring station, which might
affect the results.
§ Major noise
sources were identified and recorded.
Water Quality Monitoring
§ The monitoring team recorded
the observations around the monitoring stations, which might affect the
results.
7.3

The
Contractor should provide sufficient preventive measures during equipment
maintenance works so as to avoid oil leakage on the
ground. In the event of any oil leakage, the Contractor should clean up the
polluted soil and handle all the materials used for this cleaning works as
chemical waste.
Concrete bunding has erected outside the CEDD combined reception office and near the
automatic wheel washing facilities for storing generator sets and oil drums.
The drain outlet of all the bunded areas should be plugged properly. Besides,
pre-cast drip trays were provided for oil drums at several areas, such as
workshop and chemical storage area. The Contractor should collect and dispose
of any stagnant water accumulated in the concrete bunding and drip trays and
handle them as chemical waste.
The Contractor should use suitable containers with proper labels
to store chemical wastes in accordance with Code of Practice on the Packaging,
Labeling and Storage of Chemical Waste. The Contractor should also advise their
workers of the proper procedures in handling the chemical waste. All the trip
tickets for chemical waste disposal were properly kept in the site office.
The Contractor was reminded to increase the frequency of
inspection and cleaning of the site drainage system, including permanent
desilting chambers, desilting facilities, oil interceptor bypass tank, DP3 and
DP4 and all the trapezoidal channels. Moreover, the Contractor should apply
approved pesticides in the stagnant water ponds.
All the runoff from the parking area should be pumped to the
desilting facilities and oil interceptors to remove suspended solids and oil
& grease prior to discharge.
