13                 environmental monitoring & audit requirements

13.1              Introduction

13.1.1.1      This section elaborates the requirements of environmental monitoring and audit (EM&A) for the construction and operational phases of the Project, based on the assessment results of the various environmental issues. 

13.1.1.2      The purpose of the EM&A programme is to ascertain and verify the assumptions implicit to, and accuracy of, EIA study predictions.  The EM&A programme includes the scope of the EM&A requirements for the Project to ensure compliance with the EIA study recommendations, to assess the effectiveness of the recommended mitigation measures and to identify any further need for additional mitigation measures or remedial action. 

13.1.1.3      The following sections summarise the recommended EM&A requirements for this Project.  Details of the requirements are provided in a stand-alone EM&A Manual.

 

13.2              Air Quality Impact

13.2.1.1      Since the construction works of the Project would be divided into sections which are in small scale, the air quality impacts would be localised and minor, and would be well controlled through the implementation of good site practices and dust suppression measures stipulated in the Air Pollution Control (Construction Dust) Regulation as well as the proposed air pollution control measures to minimise the exhaust emissions from NRMMs and odour nuisance.  No adverse air quality impact due to the construction of the Project would therefore be anticipated.  Nonetheless, dust monitoring is recommended during the construction of the underground stormwater storage tank at Kwei Tei Street Playground to ascertain that there would be no adverse dust impacts at the nearby sensitive receivers.  Regular weekly site environmental audit is also recommended to ensure the implementation of recommended mitigation measures during the construction phase.  Details of the monitoring and audit programme are contained in a stand-alone EM&A Manual.  No EM&A programme is required during the operational phase.

 

13.3              Noise Impact

13.3.1.1      Noise monitoring is recommended as part of the environmental monitoring and audit (EM&A) programme for the construction phase of the Project to check compliance with the daytime construction noise criteria.  Weekly site audit is also recommended to ensure the proper implementation of the recommended mitigation measures for daytime construction activities as part of the EM&A programme.  Details of the EM&A requirements are provided in the EM&A Manual. 

13.3.1.2      No adverse noise impact is anticipated during the proposed submersible water pumps installed under the nullah bed at mid-stream of FTN  based on the plant inventory provided by the Project Engineer at the time of the assessment. Commissioning test should be conducted prior to operation of the Project to ensure that the fixed plant noise impact would comply with the relevant noise standards.  No EM&A programme is required during the operational phase.

 

13.4              Water Quality Impact

13.4.1.1      With proper implementation of the recommended pollution control measures, water pollution from the Project would be avoided and minimised and no adverse water quality impacts would be expected during construction and operational phases. Water quality monitoring is therefore not considered necessary.  Nonetheless, weekly site audit should be undertaken during the construction phase to ensure the recommended pollution control measures are properly implemented.  No EM&A requirement is considered necessary during the operational phase.

 

13.5              Waste Management Implications

13.5.1.1      Waste management would be the contractor’s responsibility to ensure that all wastes produced during the construction of the Project are handled, stored and disposed of in accordance with the recommended good waste management practices and relevant legislation and waste management guidelines.  The recommended mitigation measures should form the basis of the site Waste Management Plan (WMP) to be developed by the Contractors as part of the Environmental Management Plan in accordance with ETWB TC(W) No. 19/2005 Environmental Management on Construction Sites and submitted to the Architect/Engineer for approval in the construction phase.  The monitoring and auditing requirement stated in ETWB TCW No.19/2005 should be followed with regard to the management of C&D materials. 

13.5.1.2      Monthly site audit should be conducted by the Environmental Team (ET) during the construction phase to check if wastes are being managed in accordance with approved procedures.  The audit should cover site inspection on all aspects of on-site waste management practices including waste generation, storage, recycling, transport and disposal.  Apart from site inspections, waste management related documents including licenses, permits, disposal and recycling records should be reviewed and audited for compliance with the legislation of the recommended good site practice and other waste management mitigation measures under the site audit.

13.5.1.3      It is expected that limited quantities of waste would be generated from the operational of the Project and adverse environmental impacts would not be anticipated with the implementation of good waste management practices following the existing practices of regular maintenance works.  Hence, no EM&A requirement is considered necessary during the operational phase.

 

13.6              Land Contamination

13.6.1.1      Since no land contamination impact is anticipated, no EM&A programme is required during the construction or operational phase.

 

13.7              Sewerage and Sewage Treatment Implications

13.7.1.1      Since no adverse impact on sewerage and sewage treatment is anticipated, no EM&A programme is required during the construction or operational phase.

 

13.8              Ecological Impact

13.8.1.1      No specific environmental monitoring for ecological impact is recommended for this Project. Monthly site audit should be carried out throughout the construction phase to ensure recommended avoidance / pollution control measures are properly implemented.  In case of non-compliance, contractor should be informed to strengthen the proposed measures accordingly.  Details of EM&A requirements are discussed in the separate EM&A Manual.  No EM&A programme is required during the operational phase.

 

13.9              Fisheries Impact

13.9.1.1      Since no unacceptable adverse fisheries impacts are anticipated during both construction and operational phases, no specific EM&A programme for fisheries impact is required. 

 

13.10           Cultural Heritage Impact

13.10.1.1    Since no cultural heritage impact is anticipated during both construction and operational phases, no EM&A programme is required.

 

13.11           Landscape and Visual Impacts

13.11.1.1    The detailed landscape and engineering design of the Project would be undertaken so as to ensure compliance with the landscape and visual mitigation measures described in Section 12.8.

13.11.1.2    A baseline review should be undertaken by the Contractor at the commencement of the construction contracts to update the status of landscape resources, character areas and VSRs and submitted to EPD and PlanD for record.  Implementation of the recommended mitigation measures should be regularly audited during the construction phase.  Details of the EM&A requirements for construction phase are discussed in the standalone EM&A Manual.  As the landscape and visual mitigation measures for operational impacts would be provided and established during the construction phase, no EM&A programme is required during the operational phase.
