Reporting Changes

As informed by the Officer from FSD Diving Rescue and Diving Rescue Centre, the trainings will be conducted during the daytime period in Year 2011. According to the EIA report, no other noise sensitive receiver was identified near the Project site area, except for the FSD Diving Rescue and Diving Training Centre. Thus, the noise monitoring during the night-time period (from 2300 to 0700) was considered not necessary for Year 2011.

With the approval from IEC & ER, the noise monitoring at monitoring station (NM6) during night-time period (from 2300 to 0700) was suspended in Year 2011. The necessity of conducting noise monitoring at this station from Year 2012 will be subject to the class arrangement by FSD and will be reviewed in the end of Year 2011.

According to the information from Hong Kong Observatory, the Hong Kong Observatory anemometer station at Cheung Sha Wan was stopped from 17 December 2010. With approval from IEC & ER, the wind direction and wind speed data were obtained from another Hong Kong Observatory anemometer station located close to the Project site, which is located in Shell Oil Depot at Tsing Yi, with effective from December 2010.

Future Key Issues

Key issues to be considered in the coming month include:

- Properly store and label oil drums and chemical containers placed on site; - Proper chemical, chemical waste and waste management; - Segregation and recycling of general refuse and construction wastes should be properly

implemented; - Collection of general refuse and construction wastes should be carried out properly and

regularly; - Site runoff should be properly collected and treated prior to discharge; - Regular review and maintenance of drainage systems and desilting facilities; - Accumulation of slurry and stagnant water within site area should be avoided; - Suppress dust generated from bentonite slurry treatment plant, excavation/earth movement

activities, soil stockpiles and haul road traffic; - Regular inspection and maintenance of machineries operated on site to avoid any dark smoke

emission and oil leakage; - Quieter powered mechanical equipment should be used; - Noise control measures, such as erection of movable noise barrier, should be properly

maintained on site; and - Proper tree protection works should be provided when carry out works near existing trees.

HATS Stage 2A,





3.5 Monitoring Methodology

3.5.1 Monitoring Procedure

(a) The sound level meter was set on a tripod at a height of 1.2 m above the ground.

(b) Façade measurements were made at all monitoring locations.

(c) The battery condition was checked to ensure the correct functioning of the meter.

(d) Parameters such as frequency weighting, the time weighting and the measurement time were set as follows:

(i) frequency weighting: A (ii) time weighting: Fast (iii) time measurement: Leq(30-minutes) during non-restricted hours i.e. 07:00 – 1900

on normal weekdays; Leq(5-minutes) x3 during restricted hours i.e. 19:00 – 23:00 and 23:00 – 07:00 of normal weekdays, whole day of Sundays and Public Holidays

(e) Prior to and after each noise measurement, the meter was calibrated using the acoustic calibrator for 94dB(A) at 1000 Hz.

V

C Water Quality

6.349 to 6.375

Construction Site Runoff and General Construction Activities

The mitigation measures as outlined in the ProPECC PN 1/94 Construction Site Drainage should be adopted where applicable.


@


January 2011

3



6.376 Effluent Discharge

There is a need to apply to EPD for a discharge licence for discharge of effluent from the construction site under the WPCO. The discharge quality must meet the requirements specified in the discharge licence. If monitoring of the treated effluent quality from the works areas is required during the construction phase of the Project, the monitoring should be carried out in accordance with the WPCO license which is under the ambit of regional office (RO) of EPD. Minimum distances of 100 m should be maintained between the discharge points of construction site effluent and the existing saltwater intakes.


V

6.377 Accidental Spillage of Chemicals Contractor must register as a chemical waste producer if chemical wastes would be produced from the construction activities. The Waste Disposal Ordinance (Cap 354) and its subsidiary regulations in particular the Waste Disposal (Chemical Waste) (General) Regulation should be observed and complied with for control of chemical wastes.

V

6.378 Any service shop and maintenance facilities should be located on hard standings within a bunded area, and sumps and oil interceptors should be provided. Maintenance of vehicles and equipment involving activities with potential for leakage and spillage should only be undertaken within the areas appropriately equipped to control these discharges.

@

6.379 Disposal of chemical wastes should be carried out in compliance with the Waste Disposal Ordinance. The Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes published under the Waste Disposal Ordinance details the requirements to deal with chemical wastes. General requirements are given as follows:

Suitable containers should be used to hold the chemical wastes to avoid leakage or spillage during storage, handling and transport.

Chemical waste containers should be suitably labelled, to notify and warn the personnel who are handling the wastes, to avoid accidents.

Storage area should be selected at a safe location on site and adequate space should be allocated to the storage area.

V


January 2011

6.380 Construction Works in Close Proximity of Storm Drains or Seafront

To minimize the potential water quality impacts from the construction works located at or near any watercourse, the practices outlined below should be adopted where applicable.

The use of less or smaller construction plants may be specified to reduce the disturbance to the storm water courses or marine environment.

Temporary storage of materials (e.g. equipment, filling materials, chemicals and fuel) and temporary stockpile of construction materials should be located well away from any water courses during carrying out of the construction works.

Stockpiling of construction materials and dusty materials should be covered and located away from any water courses.

Construction debris and spoil should be covered up and/or disposed of as soon as possible to avoid being washed into the nearby water receivers.

Construction activities, which generate large amount of wastewater, should be carried out in a distance away from the waterfront, where practicable.

Proper shoring may need to be erected in order to prevent soil/mud from slipping into the storm culvert or sea.


V

D Waste Management

9.107 Reusable steel or concrete panel shutters, fencing and hoarding and signboard should be used as a preferred alternative to items made of wood, to minimise wastage of wood. Attention should be paid to WBTC No. 19/2001 - Metallic Site Hoardings and Signboards to reduce the amount of timber used on construction sites. Metallic alternatives to timber are readily available and should be used rather than new timber. Precast concrete units should be adopted wherever feasible to minimize the use of timber formwork.


V


January 2011

9.109 All waste materials should be segregated into categories covering:

excavated materials suitable for reuse on-site; excavated materials suitable for public filling facilities; remaining C&D waste for landfill; chemical waste; and general refuse for landfill.


V

9.113 Sort C&D waste from demolition of existing facilities to recover recyclable portions such as metals;

N/A

Segregation and storage of different types of waste in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal.

V

Encourage collection of aluminium cans, PET bottles and paper by providing separate labelled bins to enable these wastes to be segregated from other general refuse generated by the work force.

V

Any unused chemicals or those with remaining functional capacity shall be recycled. V

Proper storage and site practices to minimise the potential for damage or contamination of construction materials. @

9.115 Nomination of an approved person, such as a site manager, to be responsible for good site practices, arrangements for collection and effective disposal to an appropriate facility, of all wastes generated at the site.

V

Training of site personnel in proper waste management and chemical waste handling procedures. V

9.115 Develop and provide toolbox talk for on-site sorting of C&D materials to enhance worker’s awareness in handling, sorting, reuse and recycling of C&D materials.

V

Provision of sufficient waste disposal points and regular collection of waste. @

Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors. V


January 2011

9.125 Bentonite slurries used in diaphragm wall construction should be reconditioned and reused wherever practicable. The disposal of residual used bentonite slurry should follow the good practice guidelines stated in ProPECC PN 1/94 “Construction Site Drainage”


V

9.131 Adequate number of portable toilets at temporary works areas or the PTWs to ensure that sewage from site staff would be properly collected.

V

9.133 General refuse should be stored in enclosed bins, skips or compaction units separating from C&D material and disposed of at designated landfill.

V

9.135 The recyclable component of the municipal waste generated by the workforce, such as aluminium cans, paper and cleansed plastic containers should be separated from other waste. Provision and collection of recycling bins for different types of recyclable waste should be set up by the Contractor. The Contractor should also be responsible for arranging recycling companies to collect these materials.

V

9.137 If chemical wastes are produced at the construction site, the Contractor would be required to register with the EPD as a chemical waste producer and to follow the guidelines stated in the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Good quality containers compatible with the chemical wastes should be used, and incompatible chemicals should be stored separately. Appropriate labels should be securely attached on each chemical waste container indicating the corresponding chemical characteristics of the chemical waste, such as explosive, flammable, oxidizing, irritant, toxic, harmful, corrosive, etc. The Contractor shall use a licensed collector to transport and dispose of the chemical wastes, to either the approved Chemical Waste Treatment Centre, or another licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.

V

9.142 Prior to excavation of the marine deposit layer, the deposit should be tested in accordance with the ETWB TC(W) No. 34/2002 and the results should be presented in a Preliminary Sediment Quality Report. The marine deposit should be disposed of at the disposal site designated by the Marine Fill Committee (MFC) or Director of Environmental Protection (DEP) depending on the test results.

1.0 INTRODUCTION

The Landscape and Visual Audit & Monitoring are conducted to fulfill the requirements of the EIA

Report during the Construction and Operational Phases of the project, and are based on the

procedures and requirements as set out in the Agreement No. CE 43/2005 (EP) Harbour Area

Treatment Works (HATS) Stage 2A EIA Study – Final Environmental Monitoring and Audit Manual.

As stated in section 11.7 and 11.08 of the EM&A Manual, all landscape and visual mitigation

measures undertaken by the Contractor during the Construction Phase and the first 12 months of the

Operational Phase shall be audited on a monthly basis to ensure compliance with the intended aims

of the mitigation measures as stated in section 11.10.

2.0 SCOPE OF AUDIT and MONITORING

The broad scope of landscape and visual monitoring and audit on mitigation measures is as detailed

below:

2.1 Construction Phase

Indentify any potential conflicts between the proposed landscape measures and any other project

works or operation requirements, and recorded for the contractor to resolve in early stage, without

compromising the intention of the mitigation measures. Also, the followings shall be monitored:

Identify topsoil where suitable to be stripped and stored for re-use in the construction of soft

landscape works;

Regular review of the progress of engineering works to identify the earliest practical opportunity

for the landscape works;

Monitoring of tree transplanting and planting operations;

Monitoring of works around the area of existing trees to be retained and protected;

Monitoring of protection works for existing trees;

Ensure planting works are carried out in accordance with the Specification and within the right

planting season;

Ensure decorative screen hoarding erected on site are compatible with the surrounding setting;

Monitoring of night-time lighting to avoid light pollution and glare.

2.2 Operation Phase

Ensure the effectiveness of the landscape and visual mitigations measures during the Operation

Phase, including:

Monitoring of the maintenance operations during the Establishment Period to ensure all plants

are well established;

Ensure the aesthetic design of the façade of PTW and associated structures are harmonized with

the surroundings;

Ensure buffer tree and shrub plantings provides adequate screening to structures, including

rooftop greening and vertical greening.

3.1.1 Matters Arising from Previous Inspections

Nil.

3.1.2 Protection of Existing Trees and Tree Works

It was observed that the lower branches of the retained trees and the tree protection zone area

were covered with splashed mud slurry. The Contractor was requested to clean up by hosing

down the tree branches and to install plastic sheets at the base of the tree protection zone area to

prevent further splashing of mud slurry, which would affect the health of the trees.

3.1.3 Recommendations

The Contractor was recommended to clean up the tree branches and tree protection zone area,

and to install plastic sheets to prevent the splashing of mud slurry.
