2.0     SUMMARY OF EM&A REQUIREMENTS

 

2.1     Air Quality

 

According to Section 1.3 of the EM&A Manual, the captioned project involves minor road widening works. Because of the short construction period (approximately 6 to 7 months), together with staged construction sequence of works which limited the extent of construction area at any one time. Therefore, air quality was monitored by means of checking the adequacy of dust mitigation measures implemented by the Contractor (Please refer to Section 2.1 of the EM&A Manual or Section 2.3.1 of this report for dust mitigation measures).  Proper implementation of dust reduction measures was adequate to mitigate dust impacts and maintain Total Suspended Particulate (TSP) concentration levels within those recommended under the Air Quality Objectives (AQO) and no further air quality monitoring was necessary.

 

All of the dust monitoring locations identified in the EIA Study are located in the vicinity of the proposed vehicular underpass (located at the Salisbury Road/Chatham Road South junction), the monitoring works of which will be carried out as part of the works east of Nathan Road by KCRC. Hence, the standard requirements of collating Baseline Monitoring Results, calculation of Action and Limit Levels etc. have been omitted from this report. These requirements was fulfilled under the EM&A for the works east of Nathan Road. Dust monitoring locations adjacent to the project works area of the captioned project are shown in Appendix D.

 

Should there be any obvious air quality deterioration as a result of the construction works, the ET will perform additional monitoring using, for example, High Volume Sampler (HVS), to measure TSP concentration levels so as to ensure that any deteriorating air quality can be readily detected and timely action is to be taken to rectify the situation.

 

According to Section 4.1 of the EM&A Manual, regular site inspections are carried out by the ET at least once per week.

 

Additional monitoring will be performed by the ET in the event of complaints from the local residents, and/or any obvious indication of deterioration of air quality is observed.

 

2.1.1  Air Sensitive Receivers

 

According to Section 7.4 of the Final EIA Report, Peninsula Hotel, YMCA Hotel, Hong Kong Space Museum, Museum of Art and Hong Kong Cultural Centre are identified as air sensitive receivers. Their locations are shown in Appendix E.

 

2.1.2  Air Quality Monitoring

 

According to Section 1.3 of the EM&A Manual, proper implementation of dust reduction measures (see Section 2.1 of the EM&A Manual or Section 3.5 of the Final EIA Report for details) was adequate to mitigate dust impacts and maintain TSP concentration levels within those recommended under the Air Quality Objectives (AQO), and no further air quality monitoring was necessary.


Should the Contractor does not implement appropriate dust mitigation measures properly during construction phase and result in deterioration of air quality, and/or complaints (including verbal complaints) are received from local residents, the ET will perform TSP concentration level measurement.

 

Monitoring parameters

 

1.     24-hour TSP concentration level for every week

 

2.     3x1-hour TSP concentration level for every six days

 

2.1.3  Monitoring Locations

 

Dust monitoring locations adjacent to the project works area of the captioned project are shown in Appendix D. According to Section 10.1.3 of the Final EIA Report, these dust monitoring locations are closest to the air sensitive receivers affected by the captioned project.

 

2.2     Noise

 

Though requirements for noise monitoring has not been specified in the EM&A Manual, during the course of site inspection carried out by the ET, the ET will closely monitor construction noise. Should there be any obvious indication of construction noise level exceedance observed by the ET during site inspections, the ET will perform additional monitoring and will carry out noise monitoring works to measure the exceedance of noise level, with reference to the Noise Control Ordinance. Measurement of construction noise level will be carried out using an Integrating Sound Level Meter with calibrator which complied with EPD's requirements.

 

Additional monitoring will be performed by the ET in the event of complaints from the local residents, and/or any obvious indication of construction noise level exceedance is observed.

 

2.2.1  Noise Sensitive Receivers

 

According to Section 4.3 of the Final EIA Report, the noise standards only apply to dwellings relying on opened windows for ventilation. Since central air-conditioning systems are provided for all hotels which do not rely on openable windows for ventilation, these noise sensitive receivers are less sensitive to noise impacts.

 

2.2.2  Noise Level Monitoring

 

During the course of site inspection, the ET will closely monitor construction noise levels.

 

Should there be any obvious indication of construction noise level exceedance observed by the ET during site inspections, and/or complaints (including verbal complaints) are received from local residents, the ET will perform construction noise measurement.


Monitoring parameters

 

1.     Leq (30 min) for the time period between 0700-1900 hours on normal weekdays

 

2.     L10 and L90 (for reference)

 

2.3     Environmental Mitigation Measures

 

2.3.1  Air Quality

 

Dust control and mitigation measures to be implemented during the construction phase are listed in Section 2.1 of the EM&A Manual and Sections 3.5 and 10.1.7 of the Final EIA Report. Some environmental mitigation measures are as follows:

 

·                     Use of regular watering to reduce dust emissions from exposed site surfaces and unpaved roads, with complete coverage, particularly during dry weather.

 

·                     Use of frequent watering for particularly dusty static construction areas and areas close to air quality sensitive receivers.

 

·                     Side enclosure and covering of any aggregate or dusty material storage piles to reduce emissions. Where this is not practicable owing to frequent usage, watering should be employed to aggregate fines.

 

·                     Tarpaulin covering of all dusty vehicle loads transported to, from and between site locations.

 

·                     Establishment and use of vehicle wheel and body washing facilities at the exit points of the site, combined with cleaning of public roads where necessary.

 

·                     Imposition of speed controls for vehicles and unpaved site roads.

 

·                     Where feasible, routing of vehicles and positioning of construction plant should be at maximum possible distance from air quality sensitive receivers.

 

·                     Instigation of an environmental monitoring and auditing program to monitor the construction process in order to enforce controls and modify methods of work if dusty conditions arise.


2.3.2  Noise

 

According to Section 4.4 of the Final EIA Report, construction noise level experienced by the noise sensitive receivers surrounding the project works area are significantly reduced by with window insulation and central air-conditioning. If the Contractor implements good site practices listed in Appendix H of the Final EIA Report, construction noise level experienced by the noise sensitive receivers will be further reduced. Some of these good site practices are as follows:

 

·                     The Contractor shall comply with and observe the Noise Control Ordinance and its subsidiary regulations in force in Hong Kong.

 

·                     Before the commencement of any works, the Engineer may require the methods of working, equipment and sound-reducing intended to be used on the site to be made available for inspection and approval to ensure that they are suitable for the project.

 

·                     The Contractor shall devise, arrange methods of working and carry out the Works in such a manner so as to minimise noise impacts on the surrounding environment, and shall provide experienced personnel with suitable training to ensure that these methods are implemented.

 

The noise reduction methods shall include, but not be limited to, scheduling of works, siting of facilities, selection of quiet equipment, and use of purpose-built acoustic panels and enclosures.

 

·                     The Contractor shall ensure that all plant and equipment to be used on site are properly maintained in good operating condition and noisy construction activities shall be effectively sound-reduced by means of silencers, mufflers, acoustic linings or shields, acoustic sheds or screens or other means to avoid disturbance to any nearby noise sensitive receivers.

 


3.0     ADVICE ON THE IMPLEMENTATION STATUS OF ENVIRONMENTAL PROTECTION AND POLLUTION CONTROL/MITIGATION MEASURES

 

An implementation schedule of environmental mitigation measures is attached in Appendix F.

 

3.1     Environmental Mitigation Measures implemented by the Contractor during the Entire Construction Period

 

The Contractor implemented adequate environmental mitigation measures to reduce dust emissions to the air sensitive receivers adjacent to the project works area by:

 

·                     Screening of the construction site with hoardings to retain as much windblown dust within the site area as possible.

 

·                     Aesthetic treatment of the hoardings to enhance their visual interest and harmony with surrounding townscape.

 

·                     Excavated materials loaded on trucks and to be transported to dumping site were covered with tarpaulin, which can effectively reduce dust emissions during transportation of dusty materials.

 

·                     Removal of surplus excavated materials from roadside to avoid dust blown up by speedy vehicles.

 

·                     Sand and aggregate stockpiles temporarily stored on site was covered with tarpaulin to reduce windblown dust.

 

·                     Covering of the excavated area with tarpaulin if work progress was not hindered.

 

·                     Regular watering of the exposed site surfaces, excavated materials and sand and aggregate stockpiles temporarily stored on site.

 

The aforementioned environmental mitigation measures are also listed in Section 2.1 of the EM&A Manual and Section 2.3 of this EM&A Report.

 

 


4.0     MONITORING RESULTS

 

In all site inspections carried out during the entire construction period, weather condition was mainly fine.

 

If adverse weather conditions were encountered (rain, wind) was encountered on the scheduled dates, site inspections were shifted one day.

 

4.1     Air Quality

 

The Contractor had implemented adequate and effective mitigation measures to reduce dust nuisance during execution of the Works during the entire construction period. Mitigation measures undertaken by the Contractor to minimise adverse dust impact on adjacent air sensitive receivers are elaborated in Section 3.1 of this report.

 

One non-compliance item on air quality was identified during the joint EM&A audit (the IEC, the Contractor and the ER) concluded on July.  No obvious air quality deterioration was recorded during the entire construction period.

 

4.2     Noise

 

Since the number of powered mechanical equipment utilised in the captioned project was small, no noise level exceedance was observed in all site inspections performed during the entire construction period.

 

No indication of noise exceedance was observed during weekly site inspections during the entire construction period.

 

4.3     Adverse effects on Air Quality and Noise Level from Non-construction Activities and/or Activities from other Construction Sites

 

No adverse effects on air quality and noise level due to non-construction activities and/or activities from other construction sites were observed in all site inspections performed during the entire construction period.

 

 


5.0     SUMMARY RECORD OF NON-COMPLIANCE, COMPLAINTS, NOTIFICATIONS OF SUMMONS AND SUCCESSFUL PROSECUTIONS

 

5.1     Non-compliance

 

Three non-compliance items were identified during the joint EM&A audit (the IEC, the Contractor and the ER) conducted on 4 July 2002.

 

Details of three non-compliance are stated as the following:-

 

1)       Aggregate and the exposed site surfaces were not covered with tarpaulin.

 

2)       No drip trays were provided underneath chemical drums.

 

3)       Tree roots of the trees affected by the captioned project were not protected with met Hessian bags.

 

5.2     Complaints and Verbal Complaints

 

No written and verbal complaints were received during the entire construction period.

 

5.3     Notifications of Summons and Successful Prosecutions

 

No notifications of summons or successful prosecutions were received during the entire construction period.

 

5.4     Review of the Reasons for and the Implications of Non-compliances

 

5.4.1  Details of the Non-compliances

 

Details of the three non-compliances identified during the joint EM&A audit (the IEC, the Contractor and the ER) conducted on 4 July 2002 are as follows:

 

1)                 Aggregate and the exposed site surfaces were not covered with tarpaulin.

 

2)                 No drip trays were provided underneath chemical drums.

 

3)                 Tree roots of the trees affected by the captioned project were not protected with wet Hessian bags.

 

Regarding non-compliance no. 1, uncovered aggregate (and other materials) and exposed site surfaces may result in dust emission nuisance due to strong wind and speedy passing vehicles.

 

Regarding non-compliance no. 2, not providing drip trays underneath chemical drums cannot hold any leaked chemicals in case of leakage, soil underneath and surrounding the chemical drums may be contaminated.


Regarding non-compliance no. 3, health of the trees without properly-protected roots may be adversely affected. The reason is that unprotected tree roots are exposed to strong sunlight and therefore water stored in the tree roots will be evaporated, and this may cause dewatering and deterioration of the tree roots and more seriously, desiccation of the whole tree structure. Regular watering can merely provide water to the tree roots, but cannot protect the tree roots and cannot effectively reduce the amount of water evaporated from the tree roots. Therefore covering the tree roots with wet Hessian bags is the most effective measures to protect the tree roots and minimise water lost from the tree roots due to evaporation.

 

5.4.2  Actions taken to rectify the Non-compliances

 

During the site inspection on 8 July 2002, all aggregates and the exposed site surfaces were observed being covered with tarpaulin. The chemical drum had already been removed and relocated at Downer’s site office.

 

During the site inspection on 29 July 2002, tree roots of the trees affected by the captioned project had been wrapped with wet Hessian bags.

 

5.5     Summary Description of the Actions taken in the event of Non-compliance and any Follow-up Procedures related to earlier Non-compliance

 

If an non-compliance item is identified during site inspection, the ET Leader will sign a site inspection proforma. The site inspection proforma records the location and description of the non-compliance identified and will propose mitigation actions to rectify the non-compliance. Such mitigation actions must be implemented and the non-compliance must be rectified within the date of confirmation stipulated in the site inspection proforma.

 

During later site inspections and ad-hoc site inspections, location of the non-compliance identified earlier is inspected to see if mitigation actions have been properly implemented to rectify the non-compliance. The Contractor is encouraged not to make the same non-compliance and will be warned if new non-compliance is identified.

 

5.6     Summary Record of all Complaints and Verbal Complaints received, Actions and Follow-up Procedures taken

 

No written and verbal complaints were received during the entire construction period.

 

5.7     Summary of Notifications of Summons and Successful Prosecutions

 

No notifications of summons or successful prosecutions were received during the entire construction period.

 

 

 


6.0     Notes on the Joint EM&A Audit Conducted on 7 August 2002

 

The joint EM&A audit (the IEC, the Contractor and the ER) conducted on 7 August 2002, no non-compliance items were identified on site.

 

Following up the last joint EM&A audit on 4 July 2002, the chemical drum had been removed from the site.

 

After the joint EM&A audit conducted on 7 August 2002, the Contractor was reminded to:

 

1)                 Cover the exposed site surface within the drainage works area with tarpaulin tauparlin; and

 

2)                 Immediately remove small piles of soil next to one of the trees.

 

 

 

 

 

 

 


7.0     REVIEW OF MONITORING METHODOLOGY ADOPTED

 

7.1     Air Quality

 

According to Section 1.3 of the EM&A Manual or Section 2.1 of this report, due to the short construction period of the captioned project (approximately 6 to 7 months), and application of staged construction sequence to limit the extent of construction area at any one time, air quality monitoring is carried out by means of checking the adequacy of dust mitigation measures implemented by the Contractor, and rigorous air quality monitoring (such as Total Suspended Particulate (TSP) level measurement using High Volume Samplers (HVS)), is not required.

 

It can be concluded that air quality monitoring methodology adopted in the captioned project is adequate. The reason is that all of the dust monitoring locations identified in the EIA Study are located in the vicinity of the proposed vehicular underpass located at the junction of Salisbury Road and Chatham Road South, and the air quality monitoring works have been carried out as part of the works east of Nathan Road by KCRC.

 

7.2     Noise

 

It can be concluded that noise monitoring methodology adopted in the captioned project is adequate. Since duration of the captioned project is short (approximately 6 to 7 months) and staged construction sequence is adopted to limit the extent of construction area at any one time, total number of construction plant and equipment is comparatively small. Consequently, construction noise produced from these plant and equipment produces relatively less adverse influence on the noise sensitive receivers.

 

 

 

 

 


8.0     REVIEW OF THE PRACTICALLY AND EFFECTIVENESS OF the EIA PROCESS AND EM&A PROGRAMME

 

8.1     Effectiveness and Efficiency of the Mitigation Measures

 

The environmental mitigation measures implemented by the Contractor have been elaborated in Section 3.1 of this report.

 

It can be concluded that these environmental mitigation measures are effective in reduction of dust nuisance since covering of dusty materials with tarpaulin and reducing dust emissions with water can effectively reduce the amount of airborne dust produced by either strong wind or speedy vehicles.

 

 

 

 

 


9.0     ADVICE ON THE SOLID AND LIQUID WASTE MANAGEMENT STATUS

 

The Contractor had carried out adequate solid and liquid waste management during construction works in accordance with the revised Waste Management Plan in August 2002.

 

9.1     Excess Excavated Materials

 

The Contractor stockpiles excavated materials which will be reused for landscaping and backfilling temporarily on site. These excavated materials are covered with tarpaulin.

 

Excavated materials which cannot be reused for backfilling were transported to either Tseung Kwan O public filling area or Tolo Harbour Reclamation Area, according to the Waste Management Plan. Such materials were covered with tarpaulin, which could effectively reduce dust emissions during transportation.

 

9.2     Construction Waste

 

According to the Waste Management Plan, the Contractor separated construction wastes which could be reused on site and recycled with those to be disposed of. This was carried out by general workforce under supervision of Foremen and charge hands. For example, timber (for formwork) was cleaned for reuse, steel was stored for reuse, reinforcement was sorted into usable lengths for recycling or reuse on site.

 

9.3     Demolition Waste

 

None of the demolition waste generated in the captioned project will be reused, according to the Waste Management Plan. Such waste is transported to either Tseung Kwan O public filling area or Tolo Harbour Reclamation Area.

 

9.4     Chemical Waste

 

No chemical waste is generated in the captioned project.

 

9.5     General Refuse

 

The Contractor deposited aluminium cans, plastic bottles and glass bottles in separately labelled bins for recycling and reuse.

 

The Contractor reduced office wastes through recycling of paper. Signs encouraging environmental awareness, such as reducing the number of photocopies to a minimum and using both sides of papers, etc., were put on in the Contractor’s site office.

 


10.0   CONCLUSION ON RETURN OF AMBIENT SCENARIO

 

Although the captioned project had been completed on 30 August 2002, the ambient environmental conditions have not been completely returned, the reasons are as follows:

 

1)                 The DSD Contract DC/98/18 site just next to Tsim Sha Tsui Ferry Pier Bus Terminus emits odour and dust frequently, which affects air quality.

 

2)                 Construction of KCRC East Rail Extensions at the junction of Nathan Road and Salisbury Road and at the junction of Chatham Road and Salisbury Road produces dust and construction noise, which may cause air quality deterioration and exceedance of construction noise level.

 

3)                 Traffic diversion due to construction of KCRC East Rail Extensions may cause traffic congestion, which hinders smooth flow of traffic. Internal combustion engines of temporary stopping vehicles will emit more suspended particulates than those in vehicles running non-stop.

 

Therefore, it can be concluded that the ambient environmental conditions have not been completely returned, though construction works of the captioned project had been completed.
