1.0        INTRODUCTION

 

China International Water & Electric Corp. (CWE) has appointed Environmental Team of ETS-Testconsult Limited (ETL) to undertake the Environmental Impact Monitoring for “Contract No.: SS Y307 – Construction of a Secondary Boundary Fence and New Sections of Primary Boundary Fence and Boundary Patrol Road (Phase 2)” (the Project) under the requirements of “Environmental Monitoring & Audit Manual (Final) – Construction of Secondary Boundary Fence and New Sections of Primary Boundary Fence and Boundary Patrol Road” (the EM&A Manual) and “the Further Environmental Permit No. FEP-05/347/2009/A - Construction of a Secondary Boundary Fence and New Sections of Primary Boundary Fence and Boundary Patrol Road” (the FEP).

 

This report documented the findings of EM&A Works conducted in February 2014.

 

 

2.0          PROJECT INFORMATION

 

2.1        Project Background

 

ASD Contract SS Y307 namely “The Construction of a Secondary Boundary Fence and New Sections of Primary Boundary Fence and Boundary Patrol Road (Phase 2)” to be executed comprise the following works generally along the boundary from Ng Tung River to Ping Yuen River (Section 3A) and from Pak Fu Shan to Lin Man Hang (Section 3C):

3.0       Work Progress in this reporting month

 

As informed by the Contractor, site activity was carried out in the reporting month:

 

§   Foundation;

§   Concrete works;

§   Metal works;

§   Backfilling works; and

§   Installation of metal works.

 

 

4.0        Impact Noise Monitoring

 

4.1        Monitoring Requirements

 

As the requirement in the EM&A Manual, impact noise monitoring was conducted for a weekly basis at designated monitoring locations.

 

4.2        Monitoring Equipment

 

Integrating Sound Level Meters used for impact noise monitoring were Type 1 sound level meters capable of giving a continuous readout of the noise level reading including equivalent continuous sound pressure level (Leq) and percentile sound pressure level (Lx). They complied with International Electro technical Commission Publications 651:1979 (Type1) and 804:1985 (Type1).

 

Table 4.1 summarized the noise monitoring equipment model used during the impact monitoring. Copies of calibration certificates and calibration summary for noise meters and calibrators used are attached in Appendix B1.

4.3       Monitoring Parameters, Duration and Frequency

 

Impact noise monitoring for the A-weighted levels Leq, L10 and L90 were recorded once per week. Data obtained from impact noise monitoring was processed and presented as below:

 

·         Daytime: three sets of 30-minute noise level monitored between 0700-1900 hrs on normal weekdays;

·         Evening-time*: three sets of 5-minute noise level monitored between 1900-2300 hrs ;

·         Night-time*: three sets of 5-minute noise level monitored between 2300-0700 hrs of next day; and

·         Holiday*: three sets of 5-minute noise level monitored between 0700-1900 hrs on holiday.

(*): Noise monitoring to be conducted only when there is construction work.

 

4.4       Monitoring Locations

 

There was eight noise monitoring stations, VH01, VH03, MTL01, LW02, MW02, WL01(R), WL03 and STK05, were required to perform impact noise monitoring during the construction phase.

 

The detail of noise monitoring locations is summarized in Table 4.2.

Remark (*):   The monitoring stations LW02, MW02, WL01(R), WL03 and STK05 are all free-field located outside the premises of the nearby NSRs since they are enclosed areas and not willing to be entered. 3 dB(A) correction had been added to the results if noise measurement was free-field.

 

In this reporting month, the major construction works were carried out at Section 3A and therefore the impact noise monitoring was implemented at LW02 and MW02. Since minor site works, such as site preparation and site clearance work, were carried out at Section 3C in this reporting month, noise monitoring performed at WL01(R) and WL03 were used as reference. No noise monitoring was required at MTL01 at Section 2 in this reporting month since no construction work was undertaken in this reporting month.

 

4.5        Monitoring Methodology

 

Instrumentation

 

Integrating Sound Level Meters were employed for noise monitoring.

 

Operation/Analysis Procedures

 

·         Sound Level Meter was set on a tripod at a height of 1.2m above the ground;

·          For free field measurement, the meter was positioned away from any nearby reflective surfaces.

·          The battery condition was checked to ensure the correct functioning of the meter:

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

 

-         Frequency weighting :  A

-         Time weighting          :  Fast

-         Time measurement    :  30 mins

·           Prior to and after each noise measurement, the meter was calibrated using a Calibrator for 94 dB at 1000HZ.  If the difference in the calibration level before and after measurement was more than 1.0 dB(A), the measurement would be considered invalid and repeat measurement would be required after re-calibration or repair of the equipment;

·           During the monitoring period, the Leq, L10 and L90 were recorded. In addition, site conditions and noise sources were recorded on a standard record sheet;

·           3dB(A) correction had been added to the results if noise measurements were free-field; and

·           Noise monitoring would be cancelled in the presence of fog, rain, storm, wind with a steady speed exceeding 5m/s, or wind gusts exceeding 10m/s.

 

Maintenance and Calibration

 

·         The microphone head of the sound level meter and calibrator are cleaned with soft cloth at quarterly intervals; and

·         The meters are sent to supplier or HOKLAS laboratory to check and calibrated at yearly intervals.

 

4.6        Actions and Limit Levels

 

The Action and Limit Levels (AL Levels) were established in accordance to the Table 4.3 of the EM&A Manual. Table 4.4 presents the AL levels for noise monitoring.

 

Table 4.3           Action and Limit Levels for Noise Monitoring

4.7        Event-Action Plans

 

Should the results of the monitoring parameters at any designated monitoring stations indicate that the noise level criteria are exceeded, the actions in accordance with the Event and Action Plan that summarized in Appendix C should be carried out.

 

4.8        Results

 

4 occasions of Day-time noise monitoring at noise monitoring stations, LW02, MW02, WL01(R) and WL03 were carried out at this reporting month.

 

No Day-time noise monitoring results at all monitoring stations exceeded the Action Level since no documented complaints on noise issue were received during the reporting period. Besides, no exceedances in Limit Level were recorded according to the results from Day-time noise monitoring. Table 4.4 summaries the noise daytime monitoring results in the reporting period.

7.2        Advice on the Solid and Liquid Waste Management Status

 

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.

 

Besides, pre-cast drip trays were provided for oil drums at several areas, such as generator and chemical storage area. The Contractor should collect and dispose of any stagnant water accumulated in the 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. No chemical waste disposal was undertaken in the reporting month.

 

The Contractor was reminded to increase the frequency of inspection and cleaning of the site drainage system, including desilting facilities. Moreover, the Contractor should apply approved pesticides in the stagnant water.
