    1      Introduction

 

              1.1     The Project

 

This is a road improvement project in West Kowloon Reclamation Development (WKRD) for completing the developments and the commissioning of the new transport facilities.

 

Apart from the additional traffic impacts arising from the major development and transport facilities in WKRD, several major junctions in the area are currently operating with insufficient capacity causing serious congestion to some existing major road corridors such as Jordan Road (JRD), Ferry Street (FST) and Canton Road (CRD).

 

To enhance the road network of the area, Transport Department commissioned the“West Kowloon Reclamation Development Traffic Study” which identified and recommended Core and Additional Schemes together with the improvement works at the junction of CRD/FST/JRD. Implementation of these schemes would enable most of the key road junctions in the study area to operate with spare capacity, and the traffic queue length would also be reduced avoiding blockage to the upstream junctions

 

The Environmental Team (ET), Environmental Pioneers & Solutions Limited (EPSL), was appointed by Vibro Construction Co. Ltd. to undertake the Environmental Monitoring and Audit (EM&A) programme during construction phase of the Proposed Road Improvement Works in West Kowloon Reclamation Development – Phase 1. The project proponent is Highways Department. This is a Designated Project under the Environmental Impact Assessment Ordinance (Cap.499). The No. of Environment Permit is EP-455/2013.

 

The construction works and EM&A programme of this project was commenced on 6 February 2016. The construction programme and project layout plan are shown in Appendix A.

       

 

              1.2     Construction Programme and Activities

A summary of the major construction activities undertaken in this reporting period is shown as follows.

 

·             Portion I – Pile Cap, Pier and Bridge Deck Construction Works

·             Portion HA – Pile Cap, Pier and Bridge Deck Construction Works

    2      Air Quality Monitoring

 

              2.1     Monitoring Locations

According to the EM&A Manual Section 3.5, four impact monitoring locations have been established for air quality monitoring, which are summarized in Table 2.1.1.

 

Table 2.1.1 Air Quality Monitoring Locations

Identification No.	Monitoring Location	Description	Parameter
AM1	Marine Department New Yau Ma Tei Public Cargo Working Area Administrative Building	Ground Floor Face to Hoi Po Road	1-hr TSP 24-hr TSP
AM2	Garden Building	Ground Floor Face to Canton Road	1-hr TSP 24-hr TSP
AM3	The Cullinan I	Ground Floor Face to Nga Cheung Road	1-hr TSP 24-hr TSP
AM4	Lai Chack Middle School	Ground Floor Face to Canton Road	1-hr TSP 24-hr TSP

 

Due to the rejection from the representatives/ property management of the premises, high volume samplers are not feasible to be installed at AM3 and AM4 for the 24-hr TSP monitoring. Alternative locations AM3-B and AM4-A are proposed accordingly. The monitoring locations are summarized in Table 2.1.2. The details of monitoring location plan are shown in Appendix C.

 

Alternative monitoring location AM4-A is adjacent to the construction site of Xiqu Centre. Power supply for AM4-A was temporarily provided by the Main Contractor of Xiqu Centre, Hip Hing Engineering Co. Ltd.. Due to the outside surface works and drainage works of Xiqu Centre, the power distribution box under Hip Hing Engineering Co. Ltd. was relocated. The power supply to AM4-A has been cut off from early August 2017. 24hr-TSP monitoring at AM4-A was ceased from August 2017. The Contractor and ET are keeping in search of another alternative location to install the HVS and the power supply for AM4-A. On the other hand, major road works (excavation and utilities diversion) are approximately to be completed in Portion Q (close to AM4-A). The Contractor will review the construction works with ET and ER to deliberate on the possibility of suspending 24-hr TSP monitoring at AM4/AM4-A.

AM3-B*1	The Cullinan II (W Hong Kong)	Ground Floor Face to The Cullinan II	22°18’16.3”N 114°09’34.5”E	24-hr TSP
AM4-A	Tsim Sha Tsui Fire Station	Ground Floor Face to Canton Road	22°18’05.5”N 114°10’04.0”E	24-hr TSP

Remark:

^*1 Monitoring station was amended from AM3-A to AM3-B from October 2016. AM3-B is located at the site boundary of Scheme I. There is no obstacle between the site (dust emission source) and monitoring point. It is more representative for monitoring the dust impact caused by the construction activities.

 

 

              2.2     Monitoring Frequency

For 1-hr TSP monitoring, the sampling frequency is at least three times in every six days when the highest dust impact occurs.

 

For 24-hr TSP monitoring, the sampling frequency is once in every six days when the highest dust impact occurs.

 

Monitoring was carried out on 4, 10, 16, 22 and 27 January 2018.

 

              2.3     Monitoring Equipment

1-hr TSP monitoring was carried out by the portable dust meters. A comparison test for the portable dust meters with the HVS was carried out to ensure the accuracy for direct reading of the portable dust meter. 24-hr TSP monitoring was carried out by the high volume samplers. The monitoring equipment is listed in Table 2.3.1 and Calibration Certificates of the equipment are shown in Appendix D.

              2.4     Monitoring Methodology and Parameters

Measurements of 1-hr TSP monitoring were taken by a Dust Trak aerosol monitor or its equivalent that is a portable and battery-operated laser photometer capable of performing real time 1-hr TSP measurements.

 

Field monitoring procedures are as follows:

·             The monitoring station was set at a point 1m from the exterior of the sensitive receivers building façade and set at a position 1.2m above the ground.

·             The battery condition was checked to ensure good functioning of the dust monitor.

·             Zero Cal was conducted to the dust monitor to each test for ensuring more accurate data.

·             Logging setup and Instrument setup such as log interval, test length, number of test and impactor adaptor will set as follows:

-          log interval : 1min

-          test length : 60mins

-          number of test : 3

-          Impactor adaptor: 100µ

·             Start the monitoring lasting 3 hours for each monitoring location

·             At the end of the monitoring period, the Average, Maximum and Minimum of each TSP test shall be recorded. In addition on a standard record sheet.

 

Measurements of 24-hr TSP monitoring were taken by High Volume Samplers (HVSs).

 

HVSs fitted with appropriate sampling inlets were employed for air quality monitoring. Each sampler was 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 of HVSs:

·             A horizontal platform with appropriate support to secure the samplers against gusty wind should be provided;

·             No two samplers should be placed less than 2 meters apart;

·             The distance between the sampler and an obstacle, such as buildings, must be at least twice the height that the obstacle protrudes above the sampler;

·             A minimum of 2 meters of separation from walls, parapets and penthouses is required for rooftop samplers;

·             A minimum of 2 meters separation from any supporting structure, measured horizontally is required;

·             No furnace or incinerator flue is nearby;

·             Airflow around the sampler is unrestricted;

·             The sampler is more than 20 meters from the dripline;

·             Any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring;

·             Permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

·             A secured supply of electricity is needed to operate the samplers.

 

Data of wind speed and wind direction was extracted from King’s Park Meteorological Station of Hong Kong Observatory. The collection of wind data meets the prescribed criteria in S.3.4.3 of the EM&A Manual.

 

Other relevant data such as monitoring location, time, weather conditions and any other special phenomena at the construction site were recorded during the measurement period.

 

              2.5     Maintenance and Calibration

Dust Trak aerosol monitors were calibrated by the manufacturer or a HOKLAS Laboratory for every year and on-site Zero Cal before every monitoring. HVSs were calibrated after installation and re-calibrated on bi-monthly basis.

 

              2.6     Quality Assurance / Quality Control Results and Detection Limits

The portable dust meter was calibrated annually by the manufacturer or a HOKLAS laboratory. HVSs were first been calibrated after installation and repeated on bi-monthly basis. Calibration Kit for HVSs was calibrated annually by the manufacturer or a HOKLAS laboratory. The detection limits of the HVSs meet with the prescribed standard. Calibration details and current Calibration Certificates are shown in Appendix D.

 

 

 

              2.7     Action and Limit Level for 1-hr TSP and 24-hr TSP

The Action and Limit levels for air quality impact monitoring results at all monitoring locations are summarized in Table 2.7.1, which would be applied for compliance assessment of air quality for this project. If the air quality monitoring results at any monitoring stations exceeded the criteria, the actions in accordance with the Event and Action Plan in Table 2.7.2 shall be taken.

              3.4     Monitoring Methodology and Parameters

The construction noise level was measured in terms of the A-weighted equivalent continuous sound pressure level, L_Aeq. L_Aeq (30minutes) was used as the monitoring parameter for the impact monitoring in the time period between 0700 to 1900 hours on normal weekdays.

       

In case of non-compliance with the construction noise criteria, more frequent monitoring, as specified in the Action plan in Table 3.6.2, shall be carried out. This additional monitoring shall be carried out until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.

 

Field monitoring procedures are as follows:

·             The monitoring station was set at a point 1m from the exterior of the sensitive receivers building façade and set at a position 1.2m above the ground. 

·             The battery condition was checked to ensure good functioning of the meter.

·             Parameters such as frequency weighting, the time weighting and the measurement time will set as follows:

-          frequency weighting : A

-          time weighting : Fast

·             Prior to and after noise measurement, the meter shall be calibrated using the calibrator for 94.0 dB at 1000 Hz. If the difference in the calibration level before and after measurement is more than 1.0 dB, the measurement will considered invalid and repeat of noise measurement is required after re-calibration or repair of the equipment.

·             The wind speed at the monitoring station shall be checked with the portable wind meter.

·             Noise monitoring should be cancelled in the presence of fog, rain, and wind with a steady speed exceeding 5 m/s, or wind with gusts exceeding 10 m/s. Noise  measurement should be paused during periods of high intrusive noise if possible and observation shall be recorded when intrusive noise is not avoided.

·             At the end of the monitoring period, the Leq, L₁₀ and L₉₀ shall be recorded. In addition, site conditions and noise sources should be recorded on a standard record sheet.

 

              3.5     Maintenance and Calibration

Monitoring equipment was calibrated by the HOKLAS Laboratory for every year and on-site calibrated before and after every monitoring.

 

              3.6     Quality Assurance / Quality Control Results and Detection Limits

The sound level meter and calibrator were calibrated annually by the HOKLAS laboratory. The detection limits of the sound level meter meet with the prescribed standard. Calibration details and current Calibration Certificates are shown in Appendix D.

 

              3.7     Action and Limit Level for Construction Noise

The Action and Limit levels for construction noise are defined in Table 3.7.1. Should exceedance of the criteria occur, action in accordance with the Action Plan in Table 3.7.2 shall be carried out.

In accordance with the established action and limited levels for impact monitoring, Five exceedances were recorded at NM4 on 4, 10, 16, 22 and 27 January 2018. Noise measurement was repeated for confirming the findings and identifying the noise source for each exceedance according to the event and action plan.

 

The noise source for causing exceedances at NM4 was from the traffic of Canton Road. The NM4 was directly affected by the noise generated from the traffic. The recorded monitoring results at the NM4 were near the baseline noise level. The exceedances were not caused by the construction works of this project.

 

During the monitoring period, traffic noise was identified as one of the noise source for NM1, NM2, NM3, NM4 and NM5. Noise levels of NM1 and NM3 may be influenced by the construction activities from other construction sites near Nga Cheung Road. Noise level of NM2 may be influenced by construction activities from other construction sites near Hoi Ting Road. Noise levels of NM4 and NM5 may be influenced by the construction activities from other construction sites near Canton Road.
