11                         Environmental Monitoring & Audit Requirements

11.1                   Project Organisation

11.1.1              A project organisation consisting of the Engineer’s Representative (ER), Independent Environmental Checker (IEC), Environmental Team (ET), Project Proponent (Water Supplies Department) and Contractor should be established to take on the responsibilities for environmental protection for the Project. The IEC will be appointed by the Project Proponent to conduct independent auditing on the overall EM&A programme including environmental and operation monitoring, implementation of mitigation measures, Environmental Monitoring and Audit (EM&A) submissions, and any other submission required under the Environmental Permit (EP). ET is responsible for conducting the EM&A programme and to ensure the Contractor's compliance with the project's environmental performance requirements. The organisation, responsibilities of respective parties and lines of communication with respect to environmental protection works are given in the EM&A Manual.

11.2                   EM&A Manual

11.2.1              EM&A is an important aspect in the EIA process which specifies the timeframe and responsibilities for the implementation of environmental mitigation measures. The requirements on environmental monitoring (including baseline and impact monitoring) are given in the EM&A Manual.

11.2.2              A project specific EM&A Manual to the Project has been prepared as part of the EIAO submission with reference to the latest design information available and Environmental Protection Department’s (EPD) generic EM&A Manual. The project specific EM&A Manual highlights the following issues:

·         Responsibilities of the Contractor, the Engineer or ER, ET, and the IEC under the context of EM&A;

·         Project organisation for the EM&A works;

·         The basis for, and description of the broad approach underlying the EM&A programme;

·         Details of the methodologies to be adopted, including all laboratories and analytical procedures, and details on quality assurance and quality control programme;

·         The rationale on which the environmental monitoring data will be evaluated and interpreted;

·         Definition of Action and Limit Levels;

·         Establishment of Event and Action Plans;

·         Requirements for reviewing pollution sources and working procedures required in the event of non-compliance with the environmental criteria and complaints; and

·         Requirements for presentation of environmental monitoring and audit data and appropriate reporting procedures.

11.2.3              The Contractor shall be requested to review the mitigation measures and Project Implementation Schedule (PIS) with respect to the design developments and construction methodology. In the case where the Contractor needs to update the mitigation measures and the PIS, an updated EM&A Manual shall be submitted to the EPD for approval. The Contractor shall seek EPD’s prior approval on these amendments before construction commences.

11.3                   Project Implementation Schedule

11.3.1              A PIS has been prepared and included in Appendix 11A and in the EM&A Manual to summarise all the required mitigation measures that need to be implemented during the design, the construction and operation phases of the Project. The implementation responsibilities will also be identified in the PIS. The EM&A Manual will also present the requirements for environmental monitoring and auditing (e.g. monitoring and audit frequency), throughout the construction and operation phases.

11.3.2              The Contractor should review the mitigation measures and PIS with respect to the design developments and construction methodology. In case the Contractor needs to update the mitigation measures and PIS, the EM&A Manual should be updated accordingly.

11.4                   EM&A Programme

11.4.1              The ET will be requested to implement and operate a monitoring programme throughout the construction period of the Project. This mechanism will include a system to report the monitoring results on the project website within a period of time, to be agreed by EPD, after the relevant monitoring data are collected.  In cases where exceedance is found, the Contractor and ET should take immediate actions to implement remediation measures following the procedures specified in the EM&A Manual.

11.4.2              Methodology and requirements of monitoring work are detailed in a standalone EM&A Manual.

Air Quality Impact

Construction Phase

11.4.3              Construction dust monitoring, regular audits and site inspections should be carried out during construction phase to ensure that dust level will comply with the relevant criteria. The dust suppression measures stipulated in Air Pollution Control (Construction Dust) Regulation, the control measures and good practices as recommended in this EIA report and the EM&A Manual are properly implemented by the Contractor to minimise the potential disturbance to the environment.

Operation Phase

11.4.4              There will be no air pollutants emission during the operation of the Project.  No adverse air quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required

Noise Impact

Construction Phase

11.4.5              With the implementation of noise control measures, no adverse noise impact anticipated during the construction phase.  However, construction noise monitoring, regular audits and site inspections should be carried out during construction phase to ensure that the construction noise levels will comply with the relevant criterion and the recommended best management practices as recommended in this EIA Report and the EM&A Manual are properly implemented by the Contractor.

Operation Phase

11.4.6              No adverse noise impact is anticipated due to the operation of the DHPS with mitigation measures in place. Commissioning test should be conducted prior to operation of the Project to ensure fixed plant noise impact would comply with the relevant noise standards. No operation noise monitoring is therefore deemed necessary.

Water Quality Impact

Construction Phase

11.4.7              With the implementation of good site practices and recommended mitigation measures, no adverse water quality impact is anticipated during the construction phase. However, regular site audit should be carried out during the entire construction phase to ensure that good site practices and mitigation measures recommended in this EIA Report and EM&A Manual are properly implemented by the Contractor.

Operation Phase

11.4.8              No adverse water quality impacts associated with the operation of the Project are expected, and thus no monitoring and audit programme would be required.

Waste Management Implications

Construction Phase

11.4.9              During construction phase, the Contractor shall manage all generated wastes in accordance with relevant legislation and guidelines. Regular audits and site inspections should be carried out to ensure proper waste management measures recommended in this EIA Report and EM&A Manual are implemented by the Contractor.

Operation Phase

11.4.10          It is expected that there would be limited quantities of waste to be generated from the operation of the Project and no adverse impacts on waste management is anticipated with the implementation of good waste management practices.  Monitoring and audit programme for the operation phase of the Project would not be required.

Land Contamination

11.4.11          Considering no potential land contamination issue is identified, no specific monitoring or audit is required.

Ecological Impact

Construction Phase

11.4.12          Mitigation measures for air, noise, water, waste and landscape aspects proposed in respective sections of this EIA Report could serve as precautionary measures to prevent and minimise any indirect disturbance impact or pollution arisen from the construction activities on the local ecology and offsite habitats. These measures include dust control measures, selection of quieter plants, use of movable noise barriers, good site practices for waste and wastewater handling, measures outlined in ProPECC Note PN1/94 to minimise surface runoff from construction site etc., according to relevant sections of this EIA Report. Regular site audit shall be conducted to ensure the recommended mitigation measures are properly implemented.

Operation Phase

11.4.13          As no adverse ecological impact is anticipated during operation phase, no specific EM&A requirement would be required during operation phase.

Landscape and Visual Impact

Construction Phase

11.4.14          The landscape and visual mitigation measures proposed should be incorporated in the landscape and engineering design. Mitigation measures to be implemented during construction should be adopted from the start of construction and be in place throughout the entire construction period.  Site audits should be undertaken during the construction phase of the Project to check that the proposed landscape and visual mitigation measures are properly implemented and maintained as per their intended objectives.

Operation Phase

11.4.15          Site audits should be undertaken during the 12-month establishment period (operation phase) to ensure the proper implementation of the recommended mitigation measures. The conditions and growth performance of the compensatory planting should be regularly checked and monitored.

Hazard to Life

11.4.16          There will be no overnight storage of explosives for this project. Transportation of explosives to site for cavern and tunnel construction will be undertaken on a daily basis.  The contractor is required to destroy any unused explosives before nightfall. Considering no overnight storage of explosives under this Project, no specific EM&A requirement is required.
