ES.01.        Civil Engineering and Development Department (hereafter referred as “CEDD”) is the Project Proponent for the Project “Site Formation and Associated Infrastructural Works for Development of Columbarium, Crematorium and Related Facilities at Sandy Ridge Cemetery” (hereafter referred as “the Project”).  The Project is a Designated Project to be implemented under Environmental Permit No. EP-534/2017.  To facilitate the Project management, the Project works were separated into three different Contracts and they are listed below.

Ÿ   CEDD Contract No. CV/2016/10 - Site Formation and Associated Infrastructural Works for Development of Columbarium at Sandy Ridge Cemetery (hereafter referred as “Contract 1”)

Ÿ   CEDD Contract No. CV/2017/02 - Infrastructural Works at Man Kam To Road and Lin Ma Hang Road for Development of Columbarium at Sandy Ridge Cemetery (hereafter referred as “Contract 2”)

Ÿ   Other CEDD’s Contract as related Development of Columbarium at Sandy Ridge Cemetery (hereafter referred as “Contract 3”)

 

ES.02.        Hsin Chong Tsun Yip Joint Venture (hereafter referred as “HCTYJV”) has been awarded the CEDD Contract No. CV/2016/10 “Site Formation and Associated Infrastructural Works for Development of Columbarium at Sandy Ridge Cemetery” on 5 December 2017.  According to the Contract requirement, HCTYJV shall take over the responsibility for part of the Environmental Permit No. EP-534/2017 for ease of management, therefore application for Further Environmental Permit was submitted by HCTYJV to EPD on 26 January 2018 and Further Environmental Permit No. FEP-01/534/2017 was granted to HCTYJV by EPD on 23 February 2018.    

 

ES.03.        Action-United Environmental Services & Consulting (hereinafter referred as “AUES”) has been commissioned by HCTYJV as an Environmental Team (hereinafter referred as “the ET”) to implement the Environmental Monitoring & Audit (EM&A) programme in accordance with the approved EM&A Manual as well as the associated duties.

 

ES.04.        According to the Further Environmental Permit (FEP-01/534/2017) and Environmental Permit (EP-534/2017) Condition 3.3, Baseline Monitoring Report shall be deposited to EPD at least one month before commencement of the construction of the Project.  The coverage of baseline monitoring includes the whole site boundary of EP-534/2017.  Baseline monitoring for air quality was conducted from 25 April 2018 to 9 May 2018 and baseline noise monitoring was conducted from 25 April 2018 to 8 May 2018.  Due to accessibility to the monitoring point, baseline water quality monitoring was conducted from 27 April 2018 to 23 May 2018 for Locations M1, M3 and M4.  Baseline Monitoring Report (ver.1) which verified by Independent Environmental Checker (IEC) was submitted to Environmental Protection Department (EPD) on 30 May 2018.  Upon receipt comment from EPD, baseline water quality monitoring at M2 was carried out from 12 July 2018 to 6 August 2018 upon the access was available.  Baseline Monitoring Report (ver.2) was submitted to EPD on 8 August 2018 before commencement of construction activities of the Contract. Further comment was issued by EPD on 15 August 2018 and the Baseline Monitoring Report (Version 3) was submitted to EPD on 13 September 2018 for endorsement.

 

ES.05.        The Baseline Monitoring Report (air, noise and water) has summarized the key findings and the rationale behind determining a set of Action and Limit Levels (A/L Levels) from the baseline data.  As notified by HCTYJV, construction works of the Contract 1 was commenced on 16 August 2018 and therefore construction phase impact monitoring was started on 16 August 2018.

 

ES.06.        The baseline monitoring results form the basis for determining the environmental acceptance criteria for the impact monitoring. The air quality, construction noise and water quality criteria, namely Action and Limit levels were established according to Approved EM&A Manual and they are given in Tables ES-1, ES-2 and ES-3 below.

Breach of Action and Limit (A/L) Levels

ES.010.    No exceedance of air quality and construction noise monitoring was recorded in this Reporting Month.  However, for water quality monitoring, a total of twelve (12) Limit Level exceedances were recorded.  Notification of Exceedance (NOE) of water quality was therefore issued.  The statistics of environmental exceedance, NOE issued and investigation of exceedance are summarized in the following table.

Note:      NOE – Notification of Exceedance

 

ES.011.    Investigation for the cause of water quality exceedances have been undertaken by ET.  Investigation results revealed that the construction activities undertaken by Contract 1 were limited since contract works commencement on 16 August 2018.  As water quality mitigation measures, wastewater treatment facilities have been implemented and exposed surface have been covered by cement motar as far as practicable to minimize generation of muddy runoff during rain.  In addition, construction of temporary drainage system was on-going.  Nevertheless, except for 24th and 25th August 2018, there were continuous heavy rainstorms since the contract commencement.  It is considered that the exceedances were related to the rainstorm and unlikely caused by the works under the Contract 1.
