        Summary of requirement of the EIA Study

      5. The scope of the Environmental Monitoring and Audit (EM&A) and Environmental Management System (EMS) requirements are identified to monitor the implementation of the mitigation measures recommended and to achieve satisfactory environmental performance during the construction and operation phases of the project.
      6. This EM&A Manual is developed based on the requirements as stipulated in Annex 21 of the EIAO-TM. A project implementation schedule containing all the EIA study recommendations and mitigation measures has been prepared and enclosed in this Manual.

       

    3. Environmental Monitoring and Audit Requirements
      1. A summary of the EIA study recommendations and mitigation measures in EM&A as an Implementation Schedule against with the construction and operation phases is given in Appendix A.

    4. Project Organisation
      1. The project organisations and lines of communication with respect to environmental protection works during construction and operational phases are shown in Appendix B. The operation organisation is purposely set up for the implementation of the EMS but it is also applicable to the EM&A implementation.
      2. Construction and Operation Organisations

      3. The Independent Checker (IC) Environmental shall not be in any way an associated body of the Contractor. The IC (Environmental) is responsible to verify the EM&A and EMS procedures and should carry out audits periodically to determine if the EM&A and EMS are being managed in accordance with the approved procedures and to see if improvement could be enhanced. The audits should look at all environmental parameters as required in the EIA study final report.
      4. The ET shall not be in any way an associated body of the Contractor. The ET leader shall have relevant professional qualifications, or have sufficient relevant EM&A experience subject to approval of the ER.
      5. Appropriate staff shall be included in the ET, under the supervision of the ET Leader, to fulfil the EM&A and EMS duties. Basically, the duties comprise the following:-

    1. to monitor the various environmental parameters as required in the EIA study final report;
    2. to investigate and audit the Contractors’ equipment and work methodologies with respect to pollution control and environmental mitigation, and anticipate environmental issues for proactive action before problems arise;
    3. to audit and prepare audit reports on the environmental monitoring data and the site environmental conditions;
    4. to report on the environmental monitoring and audit results to the Contractor, the ER, and the ET Leader.

 

Operation Organisation

      1. The Green Manager should preferably a senior executive who can take the responsibilities for the environmental performance of NWFB. A Green Manager can help in the following ways:-

    1. Coordinate and consolidate efforts from staff of different operations into environmental programmes;
    2. Communicate the objectives of the environmental programmes to staff, and solicit their suggestions and support;
    3. Oversee the progress of environmental programmes;
    4. Ensure that good business results are achieved through the environmental programmes; and
    5. Provide a contact point for sharing environmental information with external parties.

      1. The Green Management Committee should comprise representatives from different functional or divisions of NWFB. This committee should take responsibility for managing the environmental issues of NWFB under the chairmanship of the Green Manager.
      2. Appropriate resources shall also be allocated under the Contractor, the ER and the Green Manager to fulfil their duties specified in this manual.

    1. Construction Programme
      1. The EIA process has been started in June 1999 and to be completed by around end of 1999. The envisaged construction period of the project will be from around the beginning of 2000 to 2001. The depot is expected to be commissioned by August 2001.
      2. Appendix C is the tentative works programme for the project. This programme is for information of the ET Leader to get an initial idea of the projection of the works. The ET Leader shall make reference to the actual works progress and programme during the construction stage to schedule the EM&A works, and the Contractor shall provide the respective information to the ET Leader for formulating the EM&A schedule.

  1. air quality
      1. According to the prediction results of the dust assessment in the EIA report, the nearby Air Sensitive Receptors (ASRs) will not be subject to adverse dust impact from the construction of the depot. However, mitigation measures have been recommended to further improve the air quality of the environment in the vicinity. The Contractor shall be responsible for the design and implementation of these measures.
      2. Dust Control during Construction Phase

      3. The following control measures are recommended according to Air Pollution Control (Construction Dust) Regulation to minimize dust emissions for the construction works:-

    • Watering program - For a construction site, watering is most effective if applied at the frequently trafficked areas including the entrance, exit and access road. A watering program with a frequency of four times daily shall be provided to give a full coverage of these frequently trafficked areas. Wheel-washing facilities including a "wheel-washing trough" and water jet spraying should also be provided at the exit of the site. Such a watering program, if effectively carried out, is capable of reducing dust emissions by about 50 per cent.
    • Good Site Practice - Stockpiles of dusty materials shall be adequately enclosed and be stored as far as practicable away from sensitive receptors. The load carried by vehicle should be covered by impervious sheeting to ensure no leakage of dusty materials from the vehicles. Enclosed chutes or hoists should be used to lower debris from upper floors.

      1. Continuous surveillance of the implementation of dust mitigation measures as mentioned above shall be carried on a weekly basis to ensure effective control of dust emissions.
      2. During the site inspections and the document review procedures as mentioned in Section 6, the ET Leader shall pay special attention to the issues relating to air quality control, and check whether the Contractor has followed the relevant contract specifications and the procedures specified under the laws of Hong Kong.
      3. The monitoring of air quality during operational phase is considered not necessary as the depot will be properly designed so that no adverse impact will be affecting the nearby ASRs.

 

  1. noise
    1. Introduction
      1. Although the prediction results of the construction noise assessment comply with the noise criterion, a limited amount of daytime noise monitoring for 30 active minutes on a bi-weekly basis shall be carried out during construction phase to ensure the construction complying with the EIAO-TM. Details are given in Sections 3.2.1 to 3.2.14.
      2. During operational phase, no residual noise impact is anticipated according to the technical assessment. However, recommendations and mitigation measures are given in Sections 3.2.15 to 3.2.17 and 3.3.2 to further reduce the noise impact on the Noise Sensitive Receivers (NSRs) during construction and operational phases.

    2. Construction Phase
    3. Noise Parameters

      1. The construction noise level shall be measured in terms of the A-weighted equivalent continuous sound pressure level (Leq). Leq (30min) shall be used as the monitoring parameter for the time period between 0700-1900 hours on normal weekdays. For all other time periods, Leq (5min) shall be employed for comparison with the NCO criteria. A sample data record sheet is shown in Appendix D for reference.
      2. Monitoring Equipment

      3. As referred to in the Technical Memorandum (TM) issued under the Noise Control Ordinance (NCO), sound level meters in compliance with the International Electrical Commission (IEC) publications 651:1979 (Type I) and 804:1985 (Type I) specifications shall be used for carrying out the noise monitoring. Immediately prior to and following each noise measurement the accuracy of the sound level meter shall be checked using an acoustic calibrator generating a known sound pressure level at a known frequency. Measurements may be accepted as valid only if the calibration levels from before and after the noise measurement agree to within 1.0dB.
      4. Noise measurements should not be made in accordance with standard acoustical principles and practices in relation to weather conditions.
      5. The ET Leader is responsible for the provision of the monitoring equipment. He shall ensure that sufficient noise measuring equipment and associated instrumentation are available for carrying out the baseline monitoring, regular impact monitoring and ad hoc monitoring. All the equipment and associated instrumentation shall be clearly labelled.
      6. Monitoring Locations

      7. The preferred locations for noise monitoring would be at the HK Technical College (Chai Wan) and Staff Quarters, Heng Fa Chuen and Tsui Wan Estate (Figure 3.1). The status and locations of noise sensitive receivers may change after issuing this manual. If such cases exist, the ET Leader shall proposed updated monitoring locations and seek approval from ER and agreement from EPD of the proposal.
      8. When alternative monitoring locations are proposed, the monitoring locations should be chosen based on the following criteria:-

    1. at locations close to the major site activities which are likely to have noise impacts;
    2. close to the noise sensitive receivers (N.B. for the purposes of this section, any domestic premises, hotel, hostel, temporary housing accommodation, hospital, medical clinic, educational institution, place of public worship, library, court of law, performing art centre should be considered as noise sensitive receiver); and
    3. for monitoring locations located in the vicinity of the sensitive receivers, care should be taken to cause minimal disturbance to the occupants during monitoring.

      1. The monitoring station shall normally be at a point 1m from the exterior of the sensitive receivers building facade and be at a position 1.2m above the ground. If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made. For reference, a correct of +3dB(A) shall be made to the free field measurements. The ET Leader shall agree with the ER on the monitoring position and the corrections adopted. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions.
      2. Baseline Monitoring

      3. Baseline noise monitoring before commencement of construction works is not normally required.
      4. Impact Monitoring of Construction Noise

      5. Noise monitoring shall be carried out at all the designated monitoring station. The monitoring frequency shall depend on the scale of the construction activities. The following is an initial guide on the regular monitoring frequency for each station on a per bi-week basis when noise generating activities are underway:-

  • one set of measurements between 0700-1900 hours on normal weekdays;

      1. No night-time construction works are scheduled to be carried out in this project. If general construction works are necessary to be carried out during restricted hours, it will be controlled by CNP system under the NCO.
      2. Noise monitoring shall be carried out at the monitoring stations for HK Technical College (Chai Wan) (TC1) during the school examination periods. The ET Leader shall liaise with the college personnel and the Examination Authority to ascertain the exact dates and times of all examination periods during the course of the contract.
      3. In case of non-compliance with the construction noise criteria, more frequent monitoring as specified in the Action Plan in the following section shall be carried out. This additional monitoring shall be continued until the recorded noise levels are rectified or proved to be irrelevant to the construction activities.
      4. Event and Action Plan for Noise

      5. The Action and Limit levels for construction noise are defined in Table 3.6.1. Should non-compliance of the criteria occurs, action in accordance with the Action Plan in Table 3.6.2 shall be carried out.

      1. Good site practice and noise management can considerably reduce the impact of the construction sites’ activities on nearby NSRs. The following measures should be followed during each phase of construction:

    • only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction programme;
    • machines and plant (such as trucks) that may be in intermittent use should be shut down between work periods or should be throttled down to a minimum;
    • plant known to emit noise strongly in one direction, should, where possible, be orientated so that the noise is directed away from nearby NSRs;
    • silencers or mufflers on construction equipment should be utilised and should be properly maintained during the construction period;
    • mobile plant should be sited as far away from NSRs as possible; and
    • material stackpiles and other structures should be effectively utilised, where practicable, to screen noise from on-site construction activities.

 

    1. Operational Phase
      1. Although the results of the noise assessment of the EIA report has shown that the nearby NSRs will not be adversely affected by the operation of the bus depot, mitigation measures are given in the following to further reduce the noise emissions from the depot. The proponent shall be responsible for the implementation of these measures.
      2. The following mitigation measures are recommended:-

    • Buses run through the nearby will adhere to the suggested routeing prepared by the Traffic Consultant (MVA (HK) Ltd) (Figure 3.2);
    • Buses will not be allowed to travel on the section of Shing Tai Road facing Heng Fa Chuen during mid-night return and early morning leaving; and
    • Monitoring of operational plant to ensure the source terms derived for the operational noise assessment are achieved both in terms of the vendor’s sound power specifications and the operational and maintenance assumptions.

 

  1. waste management
      1. The Contractor is responsible for waste control within the project site, removal of the waste material produced from the site and to implement any mitigation measures to minimise waste or redress problems arising from the waste from the site.
      2. The waste material may include any sewage, wastewater or effluent containing sand, cement, slit or any other suspended or dissolved material to flow from the site onto any adjoining land, storm sewer, sanitary sewer, or any waste matter or refuse to be deposited anywhere within the site or onto any adjoining land.
      3. Adequate, environmentally acceptable waste handling, storage, collection, transfer, treatment and disposal facilities should be provided to deal with the waste arising from the depot operation so as to meet the established criteria.
      4. Solid Waste Management

      5. Excavated materials – Excavated materials should be segregated from other wastes to avoid possible contamination, thereby allowing reuse on-site or at the public filling areas. The amount of excavated material to be generated from the construction activities will be small.
      6. Construction and Demolition Waste

    • Careful design and planning and good site management can minimise over ordering and generation of waste materials. The Contractor should reuse and recycle as much as possible of the C&D material on-site.
    • Proper segregation of wastes into different waste and material types on-site will increase the feasibility that certain components of the waste stream can be reused and recycled by specialised contractors. Surplus C&D materials should be segregated onsite into public fill (inert) and C&D waste for the disposal of at public filling areas and landfill, respectively.
    • A trip-ticket system to monitor the disposal of C&D materials shall be included in the tender document and implemented by the Environmental Team. Independent Checker (Environment) should be responsible for auditing the result of the system.
    • The requirements for the handling and disposal of bentonite slurries, construction effluent, sewerage and trade effluent should follow the Practice Note For Professional Persons: Construction Site Drainage, Professional Persons Consultative Committee, 1994 (ProPECC PN 1/94).

      1. Chemical Waste

    • The chemical wastes should be segregated and stored in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal. An on-site temporary storage area should be provided .
    • Chemical wastes that is produced, as defined by Schedule 1 of the Waste Disposal (Chemical Waste) (General) Regulation, should be handled in accordance with the Code of Practice on the Packaging, Labelling and Storage of Chemical.

      1. General Refuse – Reuse and recycle should be considered if possible. General refuse generated on-site should be stored in enclosed bins or compaction units separate from construction and chemical wastes. A reputable waste collector should be employed by the Contractor to remove general refuse from the site, separately from construction and chemical waste, on a daily or every second day basis to minimise odour, pest and litter impacts. The burning of refuse on-site is prohibited by law.
      2. Wastewater Management

      3. Construction effluent including, inter alia, sewage and trade effluent arising from construction phase of the site will be treated to comply with ProPECC PN 1/94 and the Technical Memorandum under Water Pollution Control Ordinance. An in-house treatment system with oil interceptors and grease traps and independent drainage system to storage tanks shall be provided within the depot. The treated effluent discharge will be complied with the limits stipulated in the Technical Memorandum on Standards for Effluents Discharged into Drainage and Sewerage Systems, Inland and Coastal Waters under Water Pollution Control Ordinance.
      4. In view of the close proximity of Chai Wan Cargo Handling Basin, no discharge of waste or wastewater will be made directly into the basin during both construction and operational phases.
      5. Adequate soil and waste and rain water drainage system, including peripheral channel around the site, will be provided for collection of drainage from the site. Adequately designed pretreatment facilities (e.g. oil interceptor, silt trap, etc) will be provided.
      6. Records of Wastes

      7. A recording system for the amount of wastes generated, recycled and disposal (including the disposal sites) will be proposed by NWFB with reference to the reporting requirements given in Section 7.
      8. Training

      9. Training will be provided by NWFB to workers about the concepts of site cleanliness and appropriate waste management procedure. All site personnel will be encouraged to reduce, reuse and recycle wastes.
      10.  

        Audits

      11. Auditing of each waste stream for the operational phase shall be carried out annually by an IC (Environmental) to determine if wastes are being managed in accordance with approved procedures and the site waste management plan and to see if waste reduction can be enhanced. The audits shall look at all aspects of waste management including waste generation, storage, recycling, transport and disposal.

 

  1. contamination avoidance
      1. The following recommendations shall be adopted to prevent land contamination associated with contaminants arising from the construction and operation of the new depot.
      2. Tank Construction

      3. It is proposed that diesel fuel will be stored in a below ground double skinned tanks situated within a concrete pit. It is proposed that leak detection equipment to monitor the interstitial space in the double skinned tank will be provided.
      4. Operation Procedures

      5. The filling and drain valves of the fuel tanks will be kept closed and locked, and the keys will be kept under the control of the engineer-in-charge.
      6. The diesel fuel storage tank will be inspected daily. The inspection will cover:-

    • verification of valve positions and security;
    • tank level checks (i.e. volume of diesel infilled, used and left in the tanks); and
    • oil/petrol interceptors to remove any accumulated sludge.

      1. Any leakage identified will be reported to the engineer-in-charge. The remaining diesel fuel in the leaking tank will immediately be transferred to appropriate containers. Daily inspection records of the tank will be kept in the site office.
      2. Tank integrity testing will be carried out on an annual basis by an independent qualified surveyor or structural engineer to ensure that the diesel fuel tanks are in good order.
      3. Tank Filling Operation

      4. Filling will be undertaken by experienced staff of the fuel company under supervision of the operator.
      5.  

        Handling Oily Waste and Sludge from Oil/Petrol Interceptor

      6. Oil/Petrol interceptors will be inspected on a daily basis. If oily waste or sludge is found to accumulate inside the interceptor, it will be reported to the engineer-in-charge. The oily waste or sludge will be removed under supervision. The sludge recovered will be put into drums and labeled as chemical waste, which will be collected and delivered by a licensed operator to a licensed chemical waste treatment facility (e.g. the Chemical Waste Treatment Centre (CWTC) at Tsing Yi) for disposal. A record of cleaning and disposal of sludge will be kept.
      7. Training

      8. To ensure that appropriate actions are taken promptly in the event of diesel fuel spillage, and to prevent land contamination, training will be given to relevant staff so that they can respond effectively to the emergency situation. The training will cover:-

    • familiarisation with resources to combat diesel fuel spillage;
    • general methods to deal with diesel fuel spillage; and
    • procedures for emergency drills.

Storage of Chemicals and Chemical Wastes

      1. Chemicals or chemical wastes will only be stored in purpose-built storage areas. For chemicals which are classified as dangerous goods under the "Dangerous Goods Ordinance", all segregation, storage and handling will comply with the requirements of the "Code of Practice on the Packaging, Labeling and Storage of Chemical Waste".
      2. The same preventative approach as described in Section 4.1.6 will apply to the storage of raw solid and liquid chemicals and chemical wastes.
      3. Recording of Incidents

      4. A detailed incident report will be compiled by the engineer-in-charge as soon as possible after any incident. The report will contain details of the incident, including an estimate of any amounts spilled, and any actions taken. The incident report will be used to evaluate any environmental impacts due to the spillage and to assess the effectiveness of the measures taken, so that improvements can be made to the response procedures for future incidents.
      5. Procedures for Disposal of Waste

      6. Used or expired chemicals, deteriorated synthetic lube oil, expired or non-usable paint and similar materials will be collected by a licensed collector and disposed of at a licensed chemical treatment facility. To avoid prolonged storage of chemical waste on site which may increase the potential for land contamination, waste will be removed from the depot on a regular basis.
      7. Audits

      8. Auditing shall be carried out annually by an IC (Environmental) for the operational phase to determine if procedures and instructions in the contamination avoidance plan have been followed to avoid contamination due to chemical or oil leaks from vehicles or machinery.

 

  1. Hazard
      1. The following recommendations shall be adopted to avoid potential hazard due to the operation of the bus depot:-

    • The following recommendations regarding the building design and layout shall be adopted to minimise the potential hazard impact:-

  1. site environmental audit
    1. Site Inspections
      1. Site Inspections provide a direct means to trigger and enforce the specified environmental protection and pollution control measures. They shall be undertaken routinely to inspect the construction activities in order to ensure that appropriate environmental protection and pollution control mitigation measures are properly implemented. With well defined pollution control and mitigation specifications and a well established site inspection, deficiency and action reporting system, the site inspection is one of the most effective tools to enforce the environmental protection requirements on the construction site.
      2. The ET Leader is responsible for formulation of the environmental site inspection, deficiency and action reporting system, and for carrying out the site inspection works. He shall submit a proposal on the site inspection, deficiency and action reporting procedures within 21 days of the construction contract commencement to the Contractor for agreement and to the ER for approval.
      3. Regular site inspections shall be carried out at least once per week. The areas of inspection shall not be limited to the environmental situation, pollution control and mitigation measures within the site; it should also review the environmental situation outside the 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 inspection:-

    1. the EIA recommendations on environmental protection and pollution control mitigation measures;
    2. works progress and programme;
    3. individual works methodology proposals (which shall include proposal on associated pollution control measures);
    4. the contract specifications on environmental protection;
    5. the relevant environmental protection and pollution control laws; and
    6. previous site inspection results.

The inspection results and its associated recommendations on improvements to the environmental protection and pollution control works shall be submitted to the ER and the Contractor within 24 hours, for reference and for taking immediate action. The Contractor shall follow the procedures and time-frame as stipulated in the environmental site inspection, deficiency and action reporting system formulated by the ET Leader to report on any remedial measures subsequent to the site inspections.
      2. Ad hoc site inspections shall also be carried out if significant 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.

    1. Compliance with Legal Requirements
      1. There are environmental protection and pollution control laws in Hong Kong which the construction activities shall comply with.
      2. In order that the works are in compliance with the legal requirements, all the works method statements submitted by the Contractor to the ER for approval shall be sent to the ET Leader for vetting to see whether sufficient environmental protection and pollution control measures have been included.
      3. 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 the any foreseeable potential for violating the laws can be prevented.
      4. The Contractor shall regularly copy relevant documents to the ET Leader so that the checking work can be carried out. The document shall at least include the updated Work Progress Reports, the updated Works Programme, the application letters for different licence/permits under the environmental protection laws, and all the valid licence/permit. The site diary shall also be available for the ET Leader’s inspection upon his request.
      5. After reviewing the document, the ET Leader shall advise the ER and the Contractor of any non-compliance with the contractual and legislative requirements on environmental protection and pollution control for them to take follow-up actions. If the ET Leader’s review concludes that the current status on licence/permit application and any environmental protection and pollution control preparation works may not cope with the works programme or may result in potential violation of environmental protection and pollution control requirements by the works in due course, he shall also advise the Contractor and the ER accordingly.
      6. Upon receipt of the advice, the Contractor shall undertake immediate action to remedial the situation. The ER shall follow up to ensure that appropriate action has been taken by the Contractor in order that the environmental protection and pollution control requirements are fulfilled.

    2. Environmental Complaints
      1. Complaints shall be referred to the ET Leader and the Green Manager for carrying out complaint investigation procedures. They shall undertake the following procedures upon receipts of the complaints:-

    1. log complaint and date of receipt onto the complaint database;
    2. investigate the complaint to determine its validity, and to assess whether the source of the problem is due to works activities;
    3. if a complaint is valid and due to works, identify mitigation measures;
    4. if mitigation measures are required, advise the Contractor accordingly;
    5. review the Contractor’s response on the identified mitigation measures, and the updated situation;
    6. if the complaint is transferred from EPD, submitted interim report to EPD on status of the complaint investigation and follow-up action within the time frame assigned by EPD;
    7. undertake additional monitoring and audit to verify the situation if necessary, and review that any valid reason for complaint does not recur;
    8. report the investigation results and the subsequent actions to the source of complaint for responding to complainant (If the source of complaint is EPD, the results should be reported within the time frame assigned by EPD); and
    9. record the complaint, investigation, the subsequent actions and the results in the monthly EM&A reports.

      1. During the complaint investigation work, the Contractor and ER shall cooperate with the ET Leader and the Green Manager in providing all the necessary information and assistance for completion of the investigation. If mitigation measures are identified in the investigation, the Contractor shall promptly carry out the mitigation. The ER shall ensure that the measures have been carried out by the Contractor.
