4. SUMMARY OF EM&A REQUIREMENTS

4.1 Air Quality

Monitoring Location

The project has one designated location for the monitoring of air quality, whichis the Site Offices. This monitoring location has been coded AM1 and it’sco-ordinates given in the following table. The air monitoring location is shownin Figure 4.1.

Table 4.1 Coordinates of AM1Station HK Metric Grid – Easting HK Metric Grid - NorthingAM1 826006 840543

Methodology

Measurement of 24-hour and 1-hour TSP levels were carried out in accordanceto the high volume sampling method as set out in the Title 40 of the Code ofFederal Regulations, Chapter 1 (Part 50). When positioning the high volumesamplers, the following requirements have been observed:

- a horizontal platform with appropriate support to secure the high volumesampler against gusty wind, should be provided;

7

- horizontal distance between the high volume samplers and an obstacle, suchas buildings, must be at least twice the height of the obstacle protrudingabove the high volume samplers;

- a minimum separation of 2 m should be provided from walls, parapets, andpenthouses for rooftop high volume samplers;

- a minimum separation of 2 m should be provided from any supportingstructure measured horizontally;

- there should not be any furnace or incinerator flues nearby;- there should be unrestricted airflow around the high volume samplers;- a minimum separation of 20 m should be provided from the dripline;- any wire fence and gate employed to protect the high volume samplers

should not cause any obstruction during monitoring.

All relevant data including elapsed time, meter reading for the start and finish ofthe sampling period, identification and weight of the filter paper, and otherspecial phenomena were recorded.

Monitoring Equipment and Calibration Details

Andersen GMW Model GS2310 high volume samplers were used to carry outthe monitoring of 24-hour and 1-hour TSP. The high volume sampler is incompliance with the specifications as listed in the EM&A Manul, given below:

- 0.6 – 1.7 m3/min (20-60 SCFM) adjustable flow range;- equipped with a timing / control device with 5 minutes accuracy over 24

hours operations;- installed with elapsed-time meter with 2 minutes accuracy over 24 hours

operations;- capable of providing a minimum exposed area of 406 cm2 (63 in2);- flow control accuracy: 2.5% deviation over 24-hr sampling period;- equipped with shelter to protect the filter and sampler;- incorporated with an electronic mass flow rate controller or other equivalent

devices;- equipped with a flow recorder for continuous monitoring;- provided with peaked roof inlet, incorporated with manometer;- able to hold and seal the filter paper to the sampler housing at horizontal

position;- easy to change filter; and- capable of operating continuously for 24-hr period.

The high volume sampler is calibrated at bi-monthly intervals. The calibrationkit (Andersen Model G2535) comprising pressure plates and a transfer standardis traceable to the internationally recognized standard. Calibration records forthe high volume sampler is given in Appendix II of this report.

Laboratory Measurement

Laboratory measurements were carried out in Stanger Asia Ltd. own HOKLASaccredited laboratory with constant temperature and humidity control, andequipped with necessary measuring and conditioning instruments.

8

Clean filter papers of size 8”x10” with no pin holes were labelled beforesampling. They were conditioned in a dessicator with less than 50% relativehumidity for over 24 hours and pre-weighed before use for sampling.After sampling, the filter papers loaded with dust were kept in a clean andtightly sealed plastic bag. The filter papers were then returned to the laboratoryfor reconditioning in the dessicator with less than 50% relative humidityfollowed by accurate weighing on an electronic balance regularly calibratedagainst a traceable standard and readable to 0.1 mg.

Stanger Asia Ltd. operates comprehensive quality assurance and quality controlprogrammes. For QA/AC procedures, all filters were equilibrated and weighedrepeatedly until the difference of two consecutive results was less than 0.5 mg.

Monitoring Parameters Frequency

1-hr TSP Three times in every six days

Action and Limit Levels

The Action levels for air quality monitoring was established from the baselinemonitoring data prior to the commencement of the construction of the project.The Limit levels for air quality monitoring has been set in line with statutoryguidelines for air quality in Hong Kong. Action and Limit levels for both 24-hour and 1-hour TSP are given in the following table.

4.2 Noise

Monitoring Location

The project has two designated Noise Monitoring Stations, Tung Chan Wai(NM1) and the pumping station (NM2). Noise monitoring for the pumpingstation (NM2) shall only be carried out on two occasions, day 1 and day 60 ofthe commissioning stage. For NM1, however, due to distance from the worksarea to the village, and the expanse of container activities in between, a smallresidential dwelling at Yan Shau Wai slightly to the north of the Tung ChanWai has been identified as being a more representative monitoring location.This monitoring location was coded as NM1(A) and construction phase noiseimpact monitoring was conducted at this station, it’s co-ordinates are listed inthe following table. The noise monitoring location is shown in Figure 4.2.

Table 4.4 Coordinates of NM1(A)Station HK Metric Grid – Easting HK Metric Grid - Northing

NM1(A) 825982 840137

Methodology

Monitoring was carried out in accordance to procedures recommended in theEnvironmental Schedule for the monitoring of construction noise as follows:

- measurements shall be recorded to the nearest 0.1dB.- Weather conditions, including a measurement of wind speed, should be

recorded for the measurement. Where the steady wind speed exceeds 5m/s, or gusts are above 10 m/s, or in the presence of fog or rain,measurements should be treated as invalid, and repeated in moreappropriate conditions.

This noise meter was programmed to measure A-weighted equivalentcontinuous sound pressure level over 5-minute intervals. Acoustic informationmeasured by the noise meter over the 30 minute (daytime period) or 15 minute(evening or holidays period) was recorded and stored with a record numberassigned to each measurement. Additional supplementary acoustical data interms of L10 and L90 were also recorded for reference and auditing.

Due to the fact that dBs are logarithmic values, they cannot be simply addedtogether and averaged. Therefore, the individual dB values are converted tolinear values. After calculation, the values are converted back to dB by takingthe logarithm and dividing the product by ten. The equation is expressed asfollows:

Average Noise Level, L eq(30 min)dB(A)

= 10 log10[{10 (L eq(5 min)i/10) + 10 (L eq(5 min)i/10) + ……..}/n]

while n is the number of the data.i is the ith data.

Monitoring Equipment and Calibration Details.

Noise levels were determined using a Brüel & Kjaer Modular precision soundlevel meter type 2231 / 2238. The meter complies with the InternationalElectrotechnical Commission Publication (IEC) 651:1979 (Type 1) and804:1985 (Type 1) specifications, as referred to in the Technical Memorandumissued under the Noise Control Ordinance (NCO).

A Brüel & Kjaer Sound level calibrator type 4231 was used for the on-sitecalibration of the meter. This calibrator complies with the IEC Publication 942(1988) Class1 and ANSI S1.40 – 1984. Noise measurements were only acceptedto be valid if the calibration levels from before and after the measurementagreed to within 1.0dB. The sound level meter and calibrator are calibratedannually by the manufacturer.

10

Wind speeds were measured by a portable anemometer, TSI model 8330VelociCheck, with direction being determined with a compass.

The calibration certificate of the sound level meter and sound level calibratorare given in Appendix II.

4.3 Water Quality

Monitoring Locations

The EM&A Manual for this project has proposed one upstream station (WM1),one down stream station (WM2) within the San Tin Drainage Channel and, oneupstream station (WM3) and one downstream station (WM4) at the dischargepoint for the San Tin Drainage Channel, once completed, within the ShenzhenRiver to be monitored for water quality.

The designated monitoring stations are shown in Figure 4.3.

Methodology

Surface water quality shall be monitored for the following parameters:Dissolved Oxygen (mg/L and % saturation), Temperature (oC), pH value,Turbidity (NTU), Water Dept (m), Suspended Solids (mg/L) and AmmoniacalNitrogen (mg/L). As the depth of the designated monitoring locations is lessthan 1.5m, only one sample was taken from mid-depth of the water column. Forin situ parameters, three measurements at each station shall be taken. Suspendedsolids and ammoniacal nitrogen shall be determined in the laboratory. All themeasurements were taken during the mid-ebb tide.

11

During monitoring works the following shall also be recorded:

- monitoring location;- depth of water;- time;- weather conditions including ambient temperature;- water temperature;- any special phenomena or activities at the construction site.

Monitoring Equipment

(a) Suspended Solids and Ammoniacal Nitrogen.

As the depth of water being sampled was generally less than 50cm, the“grab sampling” technique was employed for the taking of watersamples for the determination of suspended solids and ammoniacalnitrogen at all designated monitoring locations.

Samples were kept in high-density polythene bottles, packed in ice andcooled to 4oC or below without being frozen for delivery to thelaboratory as soon as possible after collection.

(b) Thermometer

A standard certified laboratory mercury thermometer with an accuracyof at least 0.5oC Celsius was employed, calibrated against a certifiedthermometer of 0.1 degree Celsius scale. This thermometer wasemployed for measuring both ambient and water temperatures.

(c) Depth Detector

As the depth of water being sampled was generally less than 50cm, aclearly marked depth gauge was employed to determine water depth atall designated monitoring locations.

(d) Dissolved Oxygen and Temperature Measuring Equipment

A YSI model 58 meter, YSI 5739 probe, YSI 5795A submersible stirrerwith reel and cable with employed.This meter measures oxygen in the ranges of 0-200% saturation and0-20mg/L O2 and has automatic temperature and salinity correctionfacility. It operates from a DC power source and measures temperaturein the range of 0-45oC.

(e) Turbidity Meter

A Hach model 2100P shall be employed.

The meter measures turbidity in the range of 0-1000NTU. It operatesfrom a DC power source.

12

The calibration certificates for the monitoring equipment are attached inAppendix II.

Laboratory Analysis

Samples were returned to Stanger Asia Ltd. own HOKLAS accreditedlaboratory, for the determination of suspended solids and ammoniacal nitrogen.Suspended solids content was determined employing Method 2540D (APHA20th Edition) and ammoniacal nitrogen in accordance with APHA Method No.4500-NH3 B & D, 18th Edition. Methods are referenced from the “Standard

Methods for the Examination of Water and Wastewater” (APHA, AWWA,WEF). The laboratory operates a QA/QC scheme for these analysis inclusive ofduplicate and spike recovery analysis.

Note: According to S 4.6 of the EM&A Manual, the water quality frequency can be reduced

from twice to once per week provided that no exceedance were recorded during the first three

months. As no exceedance has been recorded since the commencement of the Project, the

frequency of monitoring was reduced to once per week as from February 2004.

Action and Limit Levels

Since baseline dissolved oxygen, suspended solids and the ammoniacal nitrogenhave exceeded the criteria stated in Table 4.7a of the EM&A Manual, anotherset of Action and Limit level have been derived in accordance with the “EM&A

Guidelines for Development Projects in Hong Kong” published in February1998 issued by EPD.
