ES.04.        In the Reporting Month, 32 Limit level water quality exceedances, namely 15 exceedances of turbidity and 17 exceedances of SS were recorded.  According to the weather information from the HKO, there was heavy rainstorm intermittently during the days of exceedance recorded.  Under the impact of rainstorm, the water quality of the watercourse was deteriorated by the stirred up sediment and runoff from the surrounding environment.  It was concluded that the exceedances were likely related to the impact of rainstorm and not caused by the work under the project.

 

ES.05.        Monthly ecological monitoring for sensitive habitat for area of Contract 1 and Contract 2 were undertaken on 10th August 2021.  After analysing survey results in August from 2018 to 2021, it is found that the species diversity in Contract 1 reduced in wetland habitat and the reduction could be due to natural fluctuation. For Contract 2, there was a drop in species richness and abundance for non-wetland habitats. It could be due to natural fluctuation.  It could be due to natural fluctuation. Good practice during construction is required to prevent environmental contamination as well as unnecessary site clearance. Continuous monitoring is also recommended to inspect any significant reduction in species diversity. 

 

ES.06.        Landscape and visual inspection at both Contracts were undertaken on 26th August 2021.  The Contractor was reminded to prevent the construction material pile within Tree Protection Zone and ensure no works is allowed within the TPZ.

 

ENVIRONMENTAL COMPLAINT

ES.07.        No environmental complaint was received in this Reporting Period.

ES.011.    In the Reporting Month, joint site inspections for Contract 1 to evaluate the site environmental performance were carried out by the Resident Engineer, ET and the Contractor of the Contract 1 on   5th, 12th, 19th and 26th August 2021.  Moreover, joint site inspections for Contract 2 by the RE, ET and the Contractor of Contract 2 were carried out on  5th, 12th, 19th and 26th August 2021.  IEC attended the both Contract joint site inspection on 19th August 2021.  No non-compliance was noted during the site inspections.

 

Future Key Issues

ES.012.    The Contractors are reminded to pay special attention on water quality mitigation measures and should fully implement the measures as recommended in the EM&A Manual, in particular to prevent surface runoff and other pollutants from flowing to local stream and Conservation Area.

 

ES.013.    During wet season, the Contractors are reminded to pay special attention on water quality mitigation measures and should fully implement the measures as recommended in the EM&A Manual, in particular to prevent surface runoff and other pollutants from flowing to local stream and Conservation Area.

 

ES.014.    Construction noise mitigation measures such as use of movable noise barriers and Quality Powered Mechanical Equipment should be properly provided to reduce construction noise impact, where appropriate.

 

ES.015.    The Contractors should properly maintain the cleanliness and tidiness of the site.  In addition, mosquito control should be performed to prevent mosquito breeding on site.
