1. Introduction

1.1. Purpose of the Manual

1.1.1. The purpose of this Environmental Monitoring & Audit (EM&A) Manual is to guide the EM&A programme prepared for the Central Reclamation Phase III (CRIII), Minimum Option to ensure compliance with the Environmental Impact Assessment (EIA) Report. This is subject to approval of the EIA Report under the statutory procedures of the EIAO and supporting Technical Memorandum. The EIA recommends procedures to:

· ensure that any environmental impacts resulting from the construction of CRIII are kept to within acceptable levels;

· check that mitigation measures have been applied and are effective, and that the appropriate corrective actions are undertaken, if and when required; and

· provide a means of checking compliance with environmental objectives, recording anomalies and documenting corrective action.

1.1.2. This Manual contains the following:

· information on the CRIII project, the project organisation and construction programme;

· general EM&A principles and the EM&A team organisation;

· monitoring parameters, schedules, Action/Limit Levels and action plans;

· complaints procedures; and

· reporting procedures.

1.1.3. The EM&A Manual has taken on a dual function since the introduction of the EIAO. These roles are:

· to provide a contract document between a Client and a contractor defining the monitoring requirements and other duties in a form that is consistent with accepted contract practice.

· To provide additional controls that are implemented through the provisions of the Environmental Permit that are applicable to the project, but for which the responsibility does not rest with the Contractor.

1.1.4. As a general note, the Independent Checker (Environment) [IC(E)] may be part of the Engineer's Team, or may be totally independent, employed under a separate contract by the project proponent. In the latter case, this Manual makes reference to items requiring agreement between the Contractor (or his monitoring team), the Engineer's Representative, relevant Government Departments and the IC(E). Attention is drawn to the possibility of requiring agreement from a third party outside the contract if the IC(E) is employed independently (refer also to paragraphs 1.5.9 and 1.5.10).

1.1.5. To simplify the contractual arrangements, it is proposed that all communication with the IC(E) will be through the ER. Therefore, no reference is made in this Manual for agreement to be reached with the IC(E) as the Contractor will not be required to contact the IC(E) directly.

1.2. Requirement for EM&A Programme

1.2.1. The criteria for the requirement for undertaking EM&A are provided by EPD, these are summarised as follows:

(a) to protect sensitive receivers from environmental impacts if mitigation is not implemented;

(b) to protect the ecosystem;

(d) to monitor the effectiveness of mitigation measures which involves a long period to establish;

(e) to monitor am unproven technology;

(f) to validate the hypothesis in analysis and design;

(g) to audit the changing project scheduling; and

(h) others.

1.2.2. Criteria a) is met as there are sensitive receivers which may be impacted by construction activities. Without mitigation for water quality, dust and noise during the construction phase, activities could cause nuisance and hence would be prejudicial to the health or well being of people, and detrimental to the marine environment. Also as there are potential water quality impacts, this further justifies the requirements for monitoring and audit. The other criteria are not relevant to this project. On this basis of Criteria a), an EM&A programme is required.

1.3. Project Description

Background

1.3.1. The proposed CRIII is located to the north-east of the main Central area in Hong Kong, on the coast of Victoria Harbour between Central and Admiralty. The site lies between Central Reclamation, Phase I and western Wan Chai. Following the rejection of ‘Full Reclamation’ proposals of over 30 hectares in size, a ‘Minimum Option’ has been proposed for CRIII in order to minimise the extent of reclamation but at the same time provide sufficient land to meet essential transport infrastructure requirements. This ‘Minimum Option’ will consist of 18 hectares of reclaimed land and will provide land for the redevelopment of several Government related facilities, existing facilities within the study area, construction of a section of the Central – Wanchai Bypass (CWB) in tunnel, the Hong Kong Station Extended Overrun Tunnel and North Island Link Protection Works (entrusted to this project), and a landscaped promenade. In order to facilitate the construction of the CRIII works the existing Government Heliport at Tamar is to be relocated to Wan Chai PCWA: the Wan Chai PCWA is to be relocted to Chai Wan Basin. In addition, the CRIII project will also involve the demolition of the existing Star Ferry and Queen’s Piers as well as the provision of necessary infrastructure such as new roads, piers, electricity sub-stations, drainage culverts, sewerage, and seawater cooling systems.

1.3.2. The reclamation will take place over a period of approximately 55 months and will be phased to ensure the continuation of drainage and seawater cooling systems. A ‘fully dredged’ construction system is to be employed that will involve the removal and disposal of up to 580,000 m³ of dredged material. It is estimated that 375,000 m³ of the material will be contaminated.

Sensitive Receivers

1.3.3. The site is in a predominantly commercial business area in Hong Kong and, consequently there are no residential sensitive receivers that may be affected by the construction of CRIII. Commercial, Government and Institutional buildings and hotels around the site are all centrally ventilated and air-conditioned. They are, therefore, not classified as noise sensitive receivers (NSRs) under the HKPSG or the EIATM. At the Hong Kong Academy of Performing Arts (HKAPA), there is an outside auditorium area. This area is rarely used for performing arts events but is considered in the EIA Report as a potential NSR. A number of air sensitive receivers have been identified in the study area, these being the air intakes for the buildings around the project site. Water quality sensitive receivers have been identified as the seawater cooling system intakes in the direct vicinity of CRIII, as well as other seawater intakes located around Victoria Harbour. No ecological sensitive receivers have been identified in the EIA report.

1.3.4. The project site and surrounding area are shown in Figure 1.1.

1.4. EIA Requirements

1.4.1. The EIA Report recommends a range of mitigation measures to control the project’s potential environmental impacts with regard to marine water quality, dust, construction waste, ecological and noise impacts. The schedule of mitigation measures as given in the EIA Report is repeated in Section 9 of this Manual.

1.5. Project Organisation

1.5.1. There is the possibility that multiple contractors may be employed at the work site. The preferred approach, therefore, is for an Independent Monitoring Team to be employed directly by the project proponent to maintain impartiality. However, this is not commonly adopted. It is normal practice to require a contractor to undertake his own monitoring which should be audited and checked by the Engineer and an Independent Checker (Environment) [IC(E)]. The project organisation is illustrated in Figure 1.2.

1.5.2. Environmental Monitoring Team Leader (ET Leader): This person should be professionally qualified with suitable experience in environmental management and planning. As a general recommendation, 7 years experience is desirable, although if the proposed ET Leader has less, agreement should be sought from the ER. Extensive knowledge of the study area is required. The ET Leader should have work experience in Hong Kong managing and providing specialist advice on environmental monitoring of infrastructure projects.

1.5.3. Site Inspection Team Leader: Requires experience working on environmental projects in Hong Kong. Extensive experience in dealing with contractors directly is required.

1.5.4. Noise/Air Specialist: Requires experience in the air and noise pollution field. Particularly skilled in the use of computer models, database design and management of monitoring programmes.

1.5.5. Consultant: Experience as an environmental consultant with a broad range of expertise both in the technical and managerial aspects of environmental assessment. Proficient in: water quality sampling, analysis and assessment; air and noise monitoring, modelling and analysis; ecology; landscape and visual impact; site assessment; and scoping exercises to identify key environmental issues.

1.5.6. Assistant Consultant: Experience in conducting on-site monitoring, data-gathering and subsequent computer-modelling data analyses.

1.5.7. The duties to be undertaken by the Environmental Monitoring Team (ET) comprise the following:

· sampling, analysis and statistical evaluation of monitoring parameters with reference to the EIA Study recommendations and requirements.

· environmental site surveillance;

· audit of compliance with environmental protection and pollution prevention and control regulations;

· monitor the implementation of the environmental mitigation;

· monitor compliance with the environmental protection clauses/specifications in the Contract;

· review construction programme and comment as necessary;

· review construction methodology and comment as necessary;

· complaint investigation , evaluation and identification of corrective measures;

· liaison with IC(E) on environmental performance matters and timely submission of relevant EM&A deliverables to IC(E) for approval; and

· advise the Contractor on environmental improvement awareness and enhancement matters etc in site; and

· timely submission of the EM&A report to the Project Proponent and the Director of Environmental Protection.

1.5.8. Appropriate resources shall be allocated by the ET to fulfil their duties specified in this manual.

1.5.9. The Independent Checker (Environment) [IC(E)] shall advise the Engineer's Representative on environmental issues related to the project. The role of the Checker shall be independent from the management of construction works; but, the Checker shall be empowered to audit the environmental performance of construction. The Checker shall have project management experience in addition to the requirements of the ET Leader stated in paragraph 1.5.7. The appointment of the Checker is subject to the approval of the Engineer's Representative.

1.5.10. The main duty of the IC(E) is to carry out environmental audit of the construction project; this shall include, inter alia, the followings :

a) Review and audit all aspects of the EM&A programme;

b) Validate and confirm the accuracy of monitoring results, monitoring equipment, monitoring locations, monitoring procedures and locations of sensitive receivers;

c) Carry out random sample check and audit on monitoring data and sampling procedures, etc;

d) Conduct random site inspection;

e) Audit the EIA recommendations and requirements against the status of implementation of environmental protection measures on site;

f) Review the effectiveness of environmental mitigation measures and project environmental performance;

g) On a needs basis, audit the Contractor's construction methodology and agree the least impact alternative in consultation with the ET Leader and the Contractor;

h) Check complaint cases and the effectiveness of corrective measures;

i) Review EM&A report submitted by the ET Leader; and

j) Feedback audit results to ET by signing off relevant EM&A documents.

1.6. Construction Works and Programme

1.6.1. The details of the construction works are described in the following sections

1.6.2. This programme is for information for the ET Leader to get an initial idea of the sequencing of the works. It may be refined and amended by the contractor(s). The ET Leader shall make reference to the actual works progress and programme during the construction stage to schedule the EM&A works. The project proponent should instruct the contractor(s) to provide the relevant programme information to the ET Leader for formulating the EM&A schedule.

1.7. Construction Sequence – Issues and Constraints

1.7.1. The construction of the reclamation for Central Reclamation Phase III is constrained by a number of factors largely associated with maintaining existing facilities and operations prior the completion of associated reprovisioned facilities. Critical issues and constraints which affect the reclamation sequence are :

· Private vessel and ferry operations from the existing Queen’s Pier, “Star” Ferry Piers and Tsim Sha Tsui East temporary ferry pontoon must be maintained until completion and opening of the reprovisioned ferry pier (Ferry Pier 8), public landing steps and refurbishment of the existing Ferry Pier 7 is completed. In addition to maintaining safe marine access during this period, adequate land access will have to be maintained for pedestrians, public transport and private vehicles. During earlier studies, it was established that the existing public landing steps to the immediate north of the PLA Headquarters at Tamar would need to be closed prior to commencing the CRIII construction works. Marine Department have confirmed that these arrangements would still apply to the Minimum Option works with the exception that the westernmost set of landing steps within the existing seawall could be retained until the reprovisioned public landing steps are completed and opened for use.

· The flows from stormwater drainage culverts F, J and K must be maintained at all times throughout the project works. Temporary diversions can be utilised subject to satisfying the DSD that the flow capacity of the temporary diversions will not cause any increased risk of upstream flooding in the existing hinterland areas.

· The operations of the existing cooling water facilities located along the Central waterfront affected by the works must be maintained until completion, commissioning and opening of the reprovisioned facilities. This requirement involves maintaining intake and outfall flows, maintaining water quality at the intake to acceptable levels and maintaining adequate maintenance access to the cooling water facilities.

· The provision of sufficient land at as early a time as possible to permit construction of the following key infrastructure works :

- The Central - Wanchai Bypass Tunnel; and

- The Hong Kong Station Extended Overrun Tunnel.

· The existing Government Heliport located to the north of Lung Wui Road is planned to be reprovisioned to the Wan Chai PCWA as soon as possible after the start of the CRIII works (further relocation of this facility is planned as part of the WDII project to enable WDII project works to be completed). To facilitate the relocation of the Heliport to this site, the Wan Chai PCWA will firstly need to be relocated to Chai Wan Basin.

1.8. Proposed Construction Sequence

1.8.1. Taking account of the issues and constraints as outlined in Section 1.7, a proposed construction sequence has been developed and is detailed in Table 1.1 below. The sequence is broadly similar to that proposed for the CRIII-FR, but adapted to take account of the reduction in reclamation area immediately to the north of the previous CRIII-FR area.

2. AIR QUALITY

2.1. Air Quality Parameters

2.1.1. The major air quality issue associated with CRIII is the potential for dust generation to cause elevated Total Suspended Particulates (TSP) levels at nearby sensitive receivers.

2.2. Total Suspended Particulates

2.2.1. Monitoring and audit of the TSP levels shall be undertaken by the ET Leader to ensure that any deteriorating air quality could be readily detected and timely action taken to rectify the situation.

2.2.2. 1-hour and 24-hour TSP levels shall be measured to indicate the impacts of construction dust on air quality. The TSP levels shall be measured by following the standard high volume sampling method as set out in the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B. Upon approval by the ER, 1-hour TSP levels can be measured by direct reading methods which are capable of producing comparable results as that by the high volume sampling method, to indicate short event impacts.

2.2.3. All relevant data including temperature, pressure, weather conditions, elapsed-time meter reading for the start and stop of the sampler, identification and weight of the filter paper, and any other local atmospheric factors affecting or affected by site conditions etc. shall be recorded down in detail. A sample data sheet is shown in Figure 2.1.

2.3. Monitoring Equipment

2.3.1. High volume samplers (HVS) to be used for carrying out the 1-hour and 24-hour TSP monitoring shall comply with the following specifications:

· 0.6-1.7 m³/min (20-60 SCFM) adjustable flow range;

· equipped with a timing/control device with +/- 5 minutes accuracy for 24 hours operation;

· installed with elapsed-time meter with +/- 2 minutes accuracy for 24 hours operation;

· capable of providing a minimum exposed area of 406 cm² (63 in²);

· flow control accuracy: +/- 2.5% deviation over 24-hour sampling period;

· equipped with a 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 a peaked roof inlet;

· incorporated with a manometer;

· able to hold and seal the filter paper to the sampler housing at horizontal position;

· easy to change the filter; and

· capable of operating continuously for 24-hour period.

2.3.2. The ET Leader is responsible for provision of the monitoring equipment. He shall ensure that sufficient number of HVSs with an appropriate calibration kit are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. The HVSs shall be equipped with an electronic mass flow controller and be calibrated against a traceable standard at regular intervals. All the equipment, calibration kit, filter papers, etc. shall be clearly labelled.

2.3.3. Initial cabibration of dust monitoring equipment shall be conducted upon installation and thereafter at bi-monthly intervals. The transfer standard shall be traceable to the internationally recognised primary standard and be calibrated annually. The calibration data shall be properly documented for future reference by the concerned parties such as the IC(E). All the data shall be converted into standard temperature and pressure condition.

2.3.4. The flow-rate of the sampler before and after the sampling exercise with the filter in position shall be verified to be constant and be recorded down in the data sheet in Figure 2.1.

2.3.5. If the ET Leader proposes to use a direct reading dust meter to measure 1-hr TSP levels, he shall submit sufficient information to the IC(E) to prove that the instrument is capable of achieving a comparable result as that of the HVS and may be used for the 1-hr sampling. The instrument shall also be calibrated regularly, and the 1-hr sampling shall be determined periodically by HVS to check the validity and accuracy of the results measured by direct reading method.

2.3.6. Wind data monitoring equipment shall also be provided and set up at conspicuous locations for logging wind speed and wind direction near to the dust monitoring locations. The equipment installation location shall be proposed by the ET Leader and agreed with the ER in consultation with the IC(E). For installation and operation of wind data monitoring equipment, the following points shall be observed:

· the wind sensors should be installed on masts at an elevated level 10m above ground so that they are clear of obstructions or turbulence caused by the buildings;

· the wind data should be captured by a data logger. The data recorded in the data logger shall be downloaded periodically for analysis at least once a month;

· the wind data monitoring equipment shall be re-calibrated at least once every six months; and

· wind direction should be divided into 16 sectors of 22.5 degrees each.

2.3.7. In exceptional situations, the ET Leader may propose alternative methods to obtain representative wind data upon approval from the ER and agreement from the IC(E).

2.3.8. The ET shall provide sufficient equipment to ensure that the monitoring commences on schedule and is not interrupted as a result equipment failure, damage, loss or routine maintenance.

2.4. Laboratory Measurement/ Analysis

2.4.1. A clean laboratory with constant temperature and humidity control, and equipped with necessary measuring and conditioning instruments, to handle the dust samples collected, shall be available for sample analysis, and equipment calibration and maintenance. The laboratory shall be HOKLAS accredited or other internationally accredited laboratory.

2.4.2. If a site laboratory is set up or a non-HOKLAS accredited laboratory is hired for carrying out the laboratory analysis, the laboratory equipment shall be approved by the ER in consultation with the IC(E). Measurement performed by the laboratory shall be demonstrated to the satisfaction of the ER and the IC(E). IC(E) shall conduct regular audit to the measurement performed by the laboratory to ensure the accuracy of measurement results. The ET Leader shall provide the ER with one copy of the Title 40 of the Code of Federal Regulations, Chapter 1 (Part 50), Appendix B for his reference.

2.4.3. Filter paper of size 8”x10” shall be labelled before sampling. It shall be a clean filter paper with no folds or pin holes, and shall be conditioned in a humidity controlled chamber for over 24-hour and be pre-weighed before use for the sampling.

2.4.4. After sampling, the filter paper loaded with dust shall be kept in a clean and tightly sealed plastic bag. The filter paper is then returned to the laboratory for reconditioning in the humidity controlled chamber followed by accurate weighing by an electronic balance with a readout down to 0.1 mg. The balance shall be regularly calibrated against a traceable standard.

2.4.5. All the collected samples shall be kept in a good condition for 6 months before disposal.

2.5. Monitoring Locations

2.5.1. Monitoring shall be conducted at two representative air sensitive receivers (ASRs). These ASRs shall be the closest to the project site and equipment shall be located as close to the potentially worst affected ASRs as is practical, although there may be practical constraints such as lack of access, power or refusal for permission to locate equipment.

2.5.2. ASRs are listed in Table 2.1 and their locations are shown in Figure 2.2. The ASR reference numbers presented are consistent with those used for the WDII and CWB EIA Studies.

2.5.3. The status and locations of dust sensitive receivers may change after issuing this manual. If such cases exist, the ET Leader shall propose updated monitoring locations and seek approval from the ER and agreement from the IC(E).

2.5.4. When alternative monitoring locations are proposed, the following criteria, as far as practicable, shall be followed :

· At the site boundary or such locations close to the major dust emission source;

· Close to the sensitive receptors; and

· Take into account the prevailing meteorological conditions.

2.5.5. The ET Leader shall agree with the ER in consultation with the IC(E) the position of the HVS for installation of the monitoring equipment. When positioning the samplers, the following points shall be noted :

· 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 metre 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 metres of separation from walls, parapets and penthouses is required for rooftop samplers;

· a minimum of 2 metre 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 metres from the dripline;

· any wire fence and gate, to protect the sampler, shall 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.

2.6. Baseline Monitoring

Total Suspended Particulates

2.6.1. The ET Leader shall carry out baseline monitoring at all of the designated monitoring locations for at least 14 consecutive days prior to the commissioning of the construction works to obtain daily 24-hr TSP samples. 1-hr sampling shall also be done at least 3 times per day while the highest dust impact is expected. Before commencing the baseline monitoring, the ET Leader shall inform the IC(E) of the baseline monitoring programme such that the IC(E) can conduct on-site audit to ensure accuracy of the baseline monitoring results.

2.6.2. During the baseline monitoring, there shall not be any construction or dust generation activities in the vicinity of the monitoring stations.

2.6.3. In case the baseline monitoring cannot be carried out at the designated monitoring locations during the baseline monitoring period, the ET Leader shall carry out the monitoring at alternative locations which can effectively represent the baseline conditions at the impact monitoring locations. The alternative baseline monitoring locations shall be approved by the ER and agreed with the IC(E).

2.6.4. In the exceptional case, when insufficient baseline monitoring data or questionable results are obtained, the ET Leader shall liaise with the IC(E) and EPD to agree on an appropriate set of data to be used as a baseline reference and submit to the ER for approval.

2.6.5. Ambient conditions may vary seasonally and shall be reviewed at three monthly intervals. If the ET Leader considers that the ambient conditions have been changed and a repeat of the baseline monitoring is required to be carried out for obtaining the updated baseline levels, the monitoring shall be at times when the Contractor's activities are not generating dust, at least in the proximity of the monitoring stations. Should change in ambient conditions be determined, the baseline levels and, in turn, the air quality criteria, shall be revised. The revised baseline levels and air quality criteria shall be agreed with the IC(E) and EPD.

2.7. Impact Monitoring

Total Suspended Particulates

2.7.1. The ET Leader shall carry out impact monitoring during the course of the works. For regular impact monitoring, the sampling frequency of at least once in every six-days, shall be strictly observed at all the monitoring stations for 24-hr TSP monitoring. For 1-hr TSP monitoring, the sampling frequency of at least three times in every six-days shall be undertaken when the highest dust impact occurs. Before commencing the impact monitoring, the ET Leader shall inform the IC(E) of the impact monitoring programme such that the IC(E) can conduct on-site audit to ensure accuracy of the impact monitoring results.

2.7.2. The specific time to start and stop the 24-hr TSP monitoring shall be clearly defined for each location and be strictly followed by the field operator.

2.7.3. In case of non-compliance with the air quality criteria, more frequent monitoring exercise, as specified in the Action Plan in Section 2.8, shall be conducted within 24 hours after the result is obtained. This additional monitoring shall be continued until the excessive dust emission or the deterioration in air quality is rectified.

2.8. Event and Action Plan for Air Quality

2.8.1. The baseline monitoring results form the basis for determining the air quality criteria for the impact monitoring. The ET Leader shall compare the impact monitoring results with air quality criteria set up for 24-hour TSP and 1-hour TSP. Table 2.2 shows the air quality criteria, namely Action and Limit levels, to be used. Should non-compliance of the air quality criteria occur, actions in accordance with the Action Plan in Table 2.3 shall be carried out .

Table 2.2 : Action and Limit Levels for Air Quality

Parameters	Action	Limit

The QA/QC shall be in accordance with the requirement of HOKLAS or international accredited scheme. The QA/QC results shall be reported. EPD may also request the laboratory to carry out analysis of known standards provided by EPD for quality assurance. Additional duplicate samples may be required by EPD for inter laboratory calibration. Remaining samples after anaysis shall be kept by the laboratory for 3 months in case repeat analysis is required. If in-house or non-standard methods are proposed, details of the method verification may also be required to be submitted to DEP. In any circumstance, the sample testing shall have comprehensive quality assurance and quality control programme. The laboratory shall be prepared to demonstrate the programmes to DEP or his representatives when requested.

4.5. Monitoring Locations

4.5.1. The marine water quality monitoring stations during the construction works are shown in Figure 4.2. These stations are chosen based on the following criteria :

i. Close to the sensitive receivers (that is, the seawater intakes of the operating saltwater pumping stations) which are directly or likely to be affected. These intakes will be relocated as the reclamation proceeds. Water Quality monitoring at the re-provisioned intakes will continue at these re-provisioned intakes after the re-provisioned pumping stations have been commissioned and are operational. For monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance during monitoring;

ii. At the boundary of the mixing zones so as to verify predictive assessment results; and

iii. Two control stations that shall be at locations representative of the project site in its undisturbed condition. Control stations should be located, as far as is practicable, both upstream and downstream of the works area.

The co-ordinates of the proposed initial monitoring stations are listed in Table 4.1. As shown in Figure 4.2, the proposed locations for the sensitive receiver monitoring stations represent the sensitive receivers that are predicted to be affected during the initial construction. Sensitive receivers at the boundary of the mixing zone have not been indicated as they will depend upon the Contractor's work sequencing and will need to be determined immediately prior to commencing reclamation works. It should also be noted that the control stations shown in Figure 4.2 are indicative and subject to further review before construction phase. During this review, the location of the impact stations for the boundary of the mixing zones shall also be re-visited. Revisions to station locations shall be submitted to EPD for approval four weeks before commencement of baseline monitoring.

Table 4.1 : Proposed Water Quality Monitoring Stations

Station Ref.	E	N
1. Princess Building Group / Mandarin Hotel	834,514.5	816,093.0
2. HSBC Headquarters Building Intakes	834,644.0	816,026.5
3. Murray Road Carpark Group / Central Government Offices Group / Furama Hotel Intakes	834,780.5	815,987.5
4. Central Barracks Intake	835,002.0	815,985.5
5. Queensway Government Offices Group / Pacific Place Intakes	835,409.0	815,839.0
6. MTRC South Intakes	835,597.5	815.857.0
7. Control Station 1	829,349.0	818,629.0
8. Control Station 2	844,170.0	814,880.0

Control stations are necessary to compare the water quality from potentially impacted sites with the ambient water quality. Control stations shall be located within the same body of water as the impact monitoring stations but should be outside the area of influence of the works and, as far as practicable, not affected by any other works. Measurements shall be taken at 3 water depths, namely, 1 m below water surface, mid-depth and 1 m above seabed, except where the water depth is less than 6m, the mid-depth station may be omitted. At monitoring stations coincident with seawater intakes, the SS and turbitity measurements should make reference to the vertical levels of the individual intake pipes. Should the water depth be less than 3m, only the mid-depth station will be monitored. The ET Leader shall seek approval from the IC(E) and DEP on all monitoring station locations. The status and locations of water quality sensitive receivers may change after issuing this manual. If such cases exist, the ET Leader shall propose updated monitoring locations and seek approval from the IC(E) and DEP.

4.5.2. When alternative monitoring locations are proposed, they should be chosen based on the following criteria:

· at locations close to and preferably at the boundary of the mixing zone of the major site activities as indicated in the EIA Final Report, which are likely to have water quality impacts;

· close to the sensitive receptors which are directly or likely to be affected;

· for monitoring locations located in the vicinity of the sensitive receptors, care should be taken to cause minimal disturbance during monitoring; and

· at two or more control stations which shall be at locations representative of the project site in its undisturbed condition. Control stations should be located, as far as is practicable, both upstream and downstream of the works area.

4.6. Baseline Monitoring

4.6.1. Baseline conditions for water quality shall be established and agreed with the DEP prior to the commencement of works. The purposes of the baseline monitoring are to establish ambient conditions prior to the commencement of the works and to demonstrate the suitability of the proposed impact, control and reference monitoring stations. The baseline conditions shall normally be established by measuring the water quality parameters specified in Section 4.1. The measurements shall be taken at all designated monitoring stations including control stations, 3 days per week, at mid-flood and mid-ebb tides, for four weeks prior to the commencement of marine works.

4.6.2. There shall not be any marine construction activities in the vicinity of the stations during the baseline monitoring.

4.6.3. In the exceptional cases when insufficient baseline monitoring data or questionable results are obtained, the ET Leader shall seek approval from the IC(E) and DEP on an appropriate set of data to be used as baseline reference.

4.6.4. Baseline monitoring schedule shall be faxed to EPD two weeks prior to commencement of baseline monitoring. The interval between 2 sets of monitoring shall be less than 36 hours.

4.6.5. Replicate in-situ measurements and sample collected from each independent sampling event are required for all parameters to ensure a robust statistically interpretable database.

4.7. Impact Monitoring

4.7.1. During the course of the marine works, monitoring shall be undertaken three days per week, at mid-flood and mid-ebb tides, with sampling/measurement at the designated monitoring stations. The interval between two sets of monitoring shall not be less than 36 hours except where there are exceedances of Action and/or Limit levels, in which case the monitoring frequency will be increased.

4.7.2. Upon completion of all marine activities, a post project monitoring exercise on water quality shall be carried out for four weeks in the same manner as the impact monitoring.

4.7.3. Proposed water quality monitoring schedule shall be faxed to EPD two weeks before the first day of the monitoring month. EPD shall also be notified immediately for any changes in schedule by fax.

4.7.4. Replicate in-situ measurements and sample collected from each independent sampling event are required for all parameters to ensure a robust statistically interpretable database.

4.8. Event and Action Plan for Water Quality

4.8.1. The water quality criteria, namely Action and Limit levels are based on the results of baseline monitoring and WQO of the relevant Water Control Zone and are shown in Table 4.2. Should the monitoring results of the water quality parameters at any designated monitoring station indicate that the water quality criteria are exceeded, the actions in accordance with the Action Plan in Table 4.3 shall be carried out. Water Supplies Department have requested that they should be informed in case the Action and Limit Levels at their seawater intake points have been exceeded.

Table 4.2 : Action and Limit Levels for Water Quality

Parameters	Action	Limit
DO in mg/l (Surface, Middle & Bottom)	Surface & Middle 1%-ile of baseline data for surface and middle layer; or Midway between 5%-ile of baseline data and limit level Bottom 1%-ile of baseline data for bottom layer; or Midway between 5%-ile of baseline data and limit level	Surface & Middle 4 mg/l except 5 mg/l for FCZ or 1%-ile of baseline data for surface and middle layer Bottom 2 mg/l or 1%-ile of baseline data for bottom layer
SS in mg/l (depth-averaged)	95%-ile of baseline data or 120% of upstream control station's SS at the same tide of the same day	99%-ile of baseline, 130% of upstream control station's SS at the same tide of the same day and specific sensitive receiver water quality requirements (e.g. required suspended solids level for concerned sea water intakes)
Turbidity (Tby) in NTU (depth-averaged)	95%-ile of baseline data or 120% of upstream control station's Tby at the same tide of the same day	99%-ile of baseline or 130% of upstream control station's Tby at the same tide of the same day

Notes: - For DO, non-compliance of the water quality limits occurs when monitoring result is lower than the limits.

- For SS and Tby, non-compliance of the water quality limits occurs when monitoring result is higher than the limits.

- All the figures given in the table are used for reference only and the EPD may amend the figures whenever it is considered necessary.

4.9.2. If the measures listed in Section 9 are not sufficient to restore the water quality to an acceptable levels upon the advice of the ET Leader, the Contractor shall liaise with the ET Leader on some other mitigation measures, propose to IC(E) and ER for approval, and carry out the mitigation measures.

7. Site Environmental Audit

7.1. Site Surveillance

7.1.1. Site Surveillance provides a direct means to assess and ensure that the project's environmental protection and pollution control measures are in compliance with the contract specifications. Site surveillance shall be undertaken regularly and routinely by the Environmental Monitoring Team to inspect the construction activities in order to ensure that appropriate environmental protection and pollution control mitigation measures are implemented in accordance with the EIA recommendations. With well defined pollution control and impact mitigation specifications and an established, efficient and remedial action reporting system, the site inspection is an effective tool to ensure acceptable environmental performance on the construction site.

7.1.2. The ET Leader is responsible for formulation of the environmental site inspection, deficiency and remedial action reporting system, and for carrying out the site inspection works. He shall in consultation with the IC(E) prepare a procedure for the site inspection, deficiency and remedial action reporting requirements; and submit to the Contractor for agreement and to the ER for approval, within 21 days of commencement of the construction contract.

7.1.3. Regular site inspections shall be carried out at least once per week for all works areas. The inspections shall cover the environmental situation, pollution control and mitigation measures within the site; they shall also review the environmental situation outside the site area which is likely to be affected, directly or indirectly, by the site activities. The ET Leader shall make reference to the following information in conducting the inspections:

· the EIA Report recommendations and requirements on environmental protection and pollution control mitigation measures;

· works progress, programmes, site/aerial photos and site plans;

· individual construction works methodology proposals (which shall include proposals on associated pollution control measures);

· the contract specifications for environmental protection and pollution prevention control;

· the relevant environmental protection and pollution control laws, Pro PECC Notes; and

· previous site inspection results.

7.1.4. The Contractor shall update the ET Leader with all relevant information of the construction contract for him to carry out the site inspections. The inspection report results and its recommendations for any necessary improvements in the project's environmental performance shall be submitted, in a site inspection performa, to the IC(E) and the Contractor within 24 hours, for reference and the taking of immediate remedial action. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, deficiency and remedial action reporting system (formulated by the ET Leader) to report on any remedial measures subsequent to the site inspections.

7.1.5.Ad hoc site inspections shall also be carried out by the ET and / or IC(E) if major unacceptable or unforeseen environmental problems are identified. Inspections may also be required subsequent to receipt of an environmental complaint, or as part of the investigation work, as specified in the Action Plan for environmental monitoring and audit.

7.2. Environmental Compliance

7.2.1. There are contractual environmental protection and pollution control requirements as well as environmental protection and pollution prevention and control laws in Hong Kong with which the construction activities shall comply.

7.2.2. The ET Leader shall also review the progress and programme of the works to check that relevant environmental laws have not been violated, and that any foreseeable potential for violating the laws can be prevented.

7.2.3. The Contractor shall regularly copy relevant documents to the ET Leader so that the checking of the project's environmental performance can be carried out effectively. The documents to be submitted by the Contractor shall include at least the updated Work Progress Reports, the Works Programme, application for any necessary licenses/permits under the environmental protection laws, and all the valid licenses/permits received to date. The site diary shall also be available for the ET Leader's inspection upon his request.

7.2.4. After reviewing the document, the ET Leader shall advise the ER and the Contractor of any non-compliance with the project contractual and legislative requirements on environmental protection and pollution control. The Contractor shall take follow-up and appropriate remedial actions. If the ET Leader’s review concludes that the current status on license/permit applications and any planned environmental protection and pollution control works may not cope with the works programme or potential violation of environmental protection and pollution control requirements may arise, he shall advise the Contractor and the ER accordingly. The review shall be copied to the IC(E) for follow-up action.

7.2.5. Upon receipt of the advice, the Contractor shall undertake immediate action to remedy the situation. The ER shall follow up to ensure that appropriate action has been taken by the Contractor in order that the project's environmental protection and pollution control requirements are fulfilled.

7.3. Choice of Construction Method

7.3.1. At times during the construction phase the Contractor may submit method statements for various aspects of construction (other than those construction methods that the EIA study has not imposed conditions; for construction methods that have been assessed in the EIA study the Contractor is bound to follow the requirements and recommendations in the EIA study). Contractor's options for alternative construction methods may introduce adverse environmental impacts into the project. It is the responsibility of the Environmental Monitoring Team Leader and the Environmental Monitoring Team, in accordance with established standards, guidelines and EIA study recommendation to review and determine the adequacy of the environmental protection and pollution control measures in the Contractor's proposal in order to ensure no unacceptable impacts would result. To achieve this end, the Environmental Monitoring Team Leader shall provide a completed copy of a Proactive Environmental Protection Proforma to the IC(E) for approval. The IC(E) shall audit the review of the construction method and endorse the proposal on the basis of no adverse environmental impacts as per all Environmental Permit Conditions, EIA Study recommendations and reports, ACE conditions and any endorsed public comments related to the project and/or any established standards or guidelines.

7.4. Environmental Complaints

7.4.1. Complaints shall be referred to the ET Leader for carrying out complaint investigation procedures. The ET Leader shall undertake the following procedures upon receipt of any complaints:

· log complaint and date of receipt onto the complaint database and inform the IC(E) immediately;

· investigate the complaint to determine its validity, and to assess whether the source of the problem is due to project works;

· if a complaint is valid and due to project works, identify mitigation measures in consultation with the IC(E);

· if mitigation measures are required, advise the Contractor accordingly;

· review the Contractor’s implementation of the identified and required mitigation measures, and the current situation;

· if the complaint is transferred from EPD, submit interim report to EPD on status of the complaint investigation and follow-up action within the time frame assigned by EPD;

· undertake additional monitoring and audit to verify the compliant if necessary, and ensure that any valid reason for complaint does not recur through proposed amendments to work methods, procedures, machines and/or equipment, etc;

· report the investigation results and the subsequent actions to the complainant (if the source of complaint is identified through EPD, the results should be reported within the time frame assigned by EPD); and

· log a record of the complaint, investigation, the subsequent actions and the results in the monthly EM&A reports.

7.4.2. During the complaint investigation work, the Contractor and ER shall co-operate with the ET Leader in providing all the necessary information and assistance for completion of the investigation. If mitigation measures (in consultation with the IC(E)) are required following the investigation, the Contractor shall promptly carry out the measures. The ER shall ensure that the measures have been carried out by the Contractor. The complaints handling procedure is shown in Table 7.1.

7	Construction Water Quality Control Requirements	Specific Meaures Associated with Dredging Works
	Construction Water Quality Control Requirements	· the use of closed clamshell (water-tight) grab dredgers to remove seriously contaminated material such that the amount of SS and other pollutants released from the marine mud and pore water can be minimised;	TDD’s Contractor	Whole reclamation area During reclamation works End of reclamation works	C	R	7
		· the prohibition of stockpiling of any moderately or seriously contaminated marine sediment, and careful control of stockpiling of any uncontaminated sediment to prevent runoff, resuspension and odour nuisances; and
		· the control of dredging and bulk reclamation filling rates within acceptable limits. Based upon the construction sequence developed for this study the maximum dredging and filling rates adopted for Final Reclamation Area East were : Maximum Dredging Rate : 184 m²/hour Maximum Daily Filling Rate : 17,727 m³/day (for bulk reclamation filling) Maximum dredging and filling rates for other reclamation sites should take account of information contained in Table 10.14 of the EIA Report and envisaged construction sequence.
		· no dredging should take place under very bad weather conditions.
		· silt curtain around dredging sites to be provided as necessary.
		Specific Measure for Marine Disposal of Dredged Materials and Maine Sand Filling Works	TDD’s Contractor	Whole reclamation area During reclamation works End of reclamation works	C	R	7
		· all vessels should be sized such that adequate clearance is maintained between vessels and the sea bed at all states of the tide to ensure that undue turbidity is not generated by turbulence from vessel movement or propeller wash;
		· all hopper barges and dredgers should be fitted with tight fitting seals to their bottom openings to prevent leakage of material;
		· loading of hopper barges should be controlled to prevent splashing of dredged or filling material to the surrounding water, and barges or hoppers should not be filled to a level which will cause the overflow of materials or polluted water during loading or transportation;
		· the works should cause no visible foam, oil, grease, scum, litter or other objectionable matter to be present on the water within the site or dumping grounds;	TDD’s Contractor	Whole reclamation area During reclamation works End of reclamation works	C	R	7
		· bulk filling should be carried out, where feasible, behind completed seawall to above high water mark. In general and where physically practical, filling should not be carried out without the seawall having been substantially completed for a distance of 100m – 200m ahead of filling; and
		· fill materials should comply with technical specification requirements and be taken from approved sources only. The maximum fines content of marine sand should be limited to 5% as assumed in the water quality assessments.
		· transport of contaminated mud (or filling material) to the marine disposal site (or works site) should, wherever possible, be by split barge of not less than 750 m³ capacity, well maintained and capable of rapid opening and discharge at the disposal site; · the dredged material should be disposed in the pit by bottom dumping, at a location within the pit specified by the MFC; · discharge should be undertaken rapidly and the hoppers should then immediately be closed. Material adhering to the sides of the hopper should not be washed out of the hopper and the hopper should remain closed until the barge next return to the disposal site; · the dumping vessel is not required to station but will be guided by the site staff managing the disposal facility. The vessel crew should be familiar with such operational procedures; · monitoring of the barge loading to ensure that loss of material does not take place during transportation; and
		· Transport barges or vessels shall be equipped with automatic self-monitoring devices.
		Specific Measures Associated with Dredging and Filling Works when CRIII Dredging and Filling Works are being constructed concurrently with WDII Dredging and Filling Works
		· deployment of silt curtains around the dredging and fill release points to contain SS within the construction site during dredging and filling; · deployment of silt screens at the cooling water intakes and WSD salt water intakes to further minimise the intake of SS within the sea water.	TDD’s Contractor	Reclamation Areas as appropriate When CRIII and WDII - Dredging and Filling Works occur concurrently End of Concurrent Works	C	R	-
		Specific Measures Associated with Floating Debris The result of the floating debris simulation has shown that the intermediate layout of the proposed reclamation has potential to trap floating rubbish. Monitoring and control of the construction activities should be taken to prevent the release of construction waste and rubbish from the construction site. Collection of floating debris should be carried out at least once every day by the CRIII Contractor, and more frequently (two or three times per day) at the water body south of the Initial Reclamation Area West and near the cooling water intakes where large substances could block the screens and filter pipes of the intakes and reduce their efficiency. Debris should be collected and taken to landfill sites for disposal.	TDD’s Contractor	Whole reclamation area During construction At end of construction	C	R	-
		Specific Measures for Dealing with Culvert L Outfall at Completion of CRIII Eastern Seawall
		As a mitigation measure, to avoid the accumulation of water borne pollutants within a temporary embayment to the east of CRIII, an impermeable barrier, suspended from a floating boom on the water surface and extending down to the seabed, will be erected by the CRIII Contractor on completion of the CRIII eastern seawall. The barrier will channel the stormwater discharge flows from Culvert L to the outside of the embayment. The CRIII Contractor will maintain this barrier until the WDII Contractor takes possession of this site, whereupon the WDII Contractor will takeover the maintenance of this barrier until the reclamation works in this area are carried out and the new Culvert L extension is constructed.	TDD's Consultant	Culvert L Outfall During Construction To handover to WDII Contractor	C	R	--
		Construction Run-off and Drainage
		· Control of Site Surface Runoff: - Surface run-off from construction sites should be discharged into storm drains via adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins. Channels or earth bunds or sand bag barriers should be provided on site to properly direct stormwater to such silt removal facilities. Perimeter channels at site boundaries should be provided where necessary. Catchpits and perimeter channels should be constructed in advance of site formation works and earthworks. - Silt removal facilities, channels and manholes should be maintained.	TDD’s Contractor	Works Area During construction End of construction	C	P,R,A,C	7
		- Construction works should be programmed to minimise soil excavation works in rainy seasons (April to September). If excavation in soil cannot be avoided, temporarily exposed slope surfaces should be covered and temporary access roads should be protected by crushed stone or gravel, as excavation proceeds. Intercepting channels should be provided. - Earthworks final surfaces should be well compacted and the subsequent permanent work or surface protection should be carried out immediately after the final surfaces are formed to prevent erosion caused by rainstorms. Appropriate drainage such as intercepting channels should be provided where necessary. - Measures should be taken to minimise the ingress of rainwater into trenches. If excavation of trenches in wet seasons is necessary, they should be dug and backfilled in short sections. Rainwater pumped out from trenches or foundation excavations should be discharged into storm drains via silt removal facilities. - Open stockpiles of construction materials should be covered. - Manholes should be adequately covered and temporarily sealed.
		· Groundwater - Groundwater pumped out of tunnels or caverns should be discharged into storm drains after the removal of silt.
		· Boring and Drilling Water - Water used in ground boring and drilling for site investigation or rock/soil anchoring should as far as practicable be recirculated after sedimentation. Wastewater should be discharged into storm drains via silt removal facilities.	TDD’s Contractor	Work Area During construction End of construction	C	P,R,A,C	7
		· Wastewater from Concrete Batching and Precast Concrete Casting - Wastewater generated from the washing down of mixer trucks and drum mixers and similar equipment should wherever practicable be recycled. The discharge of wastewater should be kept to a minimum. - To prevent pollution from wastewater overflow, the pump sump of any water recycling system should be provided with an on-line standby pump of adequate capacity and with automatic alternating devices. - Under normal circumstances, surplus wastewater may be discharged into foul sewers after treatment in silt removal and pH adjustment facilities (to within the pH range of 6 to 10). Disposal of wastewater into storm drains will require more elaborate treatment. Surface run-off should be segregated from the concrete mixing and casting yard area as much as possible, and diverted to the stormwater drainage system. Surface run-off contaminated by materials in a concrete mixing area or casting yard should be adequately treated before disposal into stormwater drains.
		· Wheel Washing Water - All vehicles and plant should be cleaned before they leave the construction site. A wheel washing bay should be provided at every site exit if practicable and wash-water should have sand and silt settled out or removed before discharging into storm drains. The section of construction road between the wheel washing bay and the public road should be paved with backfall to reduce vehicle tracking of soil and to prevent site run-off from entering public road drains.	TDD’s Contractor	Work Area During construction End of construction	C	P,R,A,C	7
		· Bentonite Slurries - Bentonite slurries should be reconditioned and reused wherever practicable. If the disposal of a certain residual quantity cannot be avoided, the used slurry may be disposed of at the marine spoil site subject to obtaining a marine dumping licence from EPD (on a case-by-case basis). - If the used bentonite slurry is intended to be disposed of through the public drainage system, it should be treated to the respective effluent standards applicable to foul sewers, storm drains or the receiving waters as set out in the WPCO Technical Memorandum on Effluent Standards.
		· Wastewater from Building Construction - Before commencing any demolition works, all sewer and drainage connections should be sealed to prevent building debris, soil, sand etc. from entering public sewers/drains. - Wastewater generated from building construction activities including concreting, plastering, internal decoration, cleaning of works and similar activities should not be discharged into the stormwater drainage system. If the wastewater is to be discharged into foul sewers, it should undergo the removal of settleable solids in a silt removal facility, and pH adjustment as necessary.
		· Licensing of Construction Site Discharges within Water Control Zones - All discharges into any drainage or sewerage systems, or inland or coastal waters, or into the ground (e.g. from septic tanks) within a Water Control Zone are controlled under the Water Pollution control Ordinance (WPCO), except the discharge of domestic sewage into foul sewers or the discharge of unpolluted water into storm drains or into the waters of Hong Kong. Construction site discharges are controlled under the WPCO. - Discharges controlled under the WPCO must comply with the terms and conditions of a valid WPCO licence.
8.	Construction Waste Control Requirements	Specific Measures Associated with Marine sediments
		In accordance with the WBTC No. 3/2000, the seriously contaminated material must be dredged and transported with great care. Mitigation measures, includeding the use of close-grab dredgers, shall be incorporated. The dredged contaminated sediment must be effectively isolated from the environment upon final disposal and shall be disposed of at the East Sha Chau Contaminated Mud Pits.	TDD's Contractor	Whole Reclamation Area During Reclamation Works End of Reclamation Work	C	R	7
		Segregation and Disposal of Wastes
		· inert demolition/construction waste material when deemed suitable for reclamation or land formation should be re-used on-site; · non-inert demolition / construction waste material should be disposed of at landfills; · chemical waste as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, should be stored in accordance with approved methods defined in the Regulation and Code of Practice and the chemical waste disposed of at the Chemical Waste Treatment Facility located at Tsing Yi or an approved recycler; · general refuse should be recycled where possible or disposed of at public landfill.	TDD's Contractor	Works Areas During Construction End of Construction	C	P, R, A, C	1,8, 9
		Storage, Collection and Transport of Waste · wastes should be handled and stored in a manner which ensures that they are held securely without loss or leakage thereby minimising the potential for pollution. Release of these potential pollutants into marine waters during storage, handling or barge transportation should not be permitted as introduction of polluted waters is likely to have detrimental effects on water quality and water sensitive receivers; · only reputable waste hauliers authorised to collect the specific category of waste concerned should be employed; · appropriate measures should be employed to minimise windblown litter and dust during transportation by using enclosed bins, covering trucks or transporting wastes in enclosed containers; · the necessary waste disposal permits and registrations should be obtained from the appropriate authorities, if they are required, in accordance with the Waste Disposal Ordinance (Cap 354), Waste Disposal (Chemical Waste) (General) Regulation (Cap 354) and the Crown Land Ordinance; · collection of general refuse should be carried out frequently, preferably daily; · waste should only be disposed of at licensed sites and the civil engineering contractor should develop procedures to ensure that illegal disposal of wastes does not occur; · waste storage areas should be well maintained and cleaned regularly; · records should be maintained of the quantities of wastes generated, recycled and disposed, determined by weighing each load or other method; and · A “trip ticket” system should be implemented, if required by Government.
