After received the details of the complaint from the ENPO, the Environmental Officers, RE and ET of Contract No. HY/2013/02 have performed a related follow-up inspection on 10 January 2018 to investigate this event. After received the details of the complaint from the ENPO, the Environmental Officers, RE and ET of Contract No. HY/2013/02 have performed a related follow-up inspection on 10 January 2018 to investigate this event. The inspection was concentrated to check if any mud/slurry and dusts produced from the construction sites of Contract No. HY/2013/02 originated to East Coast Road and if any mud/slurry and dusts accumulated on the road side of East Coast Road. After checked with the RE and the Contractor of Contract No. HY/2013/02 during 10:00 to 11:00 on 10 January 2018, the site entrance was cleaned and no mud/slurry was observed around the East Coast Road site entrance. Besides, high pressure water jet was provided at site exit in order to prevent any mud/slurry bringing out from the site (see attached photo). The site entrance situation was acceptable according to the site inspection on 10 January 2018. In addition, mitigation measures under the item A2 and W2 of EMIS were implemented including provide vehicle washing facilities with high pressure water jet, the road section between the washing facilities and the exit point was hard paved and reminders were provided at the wheel washing basin and exit to remind all Contract(s) vehicles using the site exit for proper wheel washing etc.

 

To monitor the implementation of mitigation measures, follow-up site inspections were performed. Mitigation measures under the item A2 and W2 of EMIS were implemented and enhanced in order to further improve the condition of the site entrance and road section between wheel-washing facilities and East Coast Road gate. Manpower was provided to stop the vehicles when passing the washing facilities in order to lengthen the washing time. Besides, washing facilities with high pressure water jet at the area where vehicle washing takes place was provided. The road section between the washing facilities and the exit point was hard paved and watering truck was arranged regularly to clean the road section. Besides washing the haul roads by watering, manpower was also assigned to remove the accumulated mud/slurry along the haul road section between wheel-washing facilities and East Coast Road gate (see attached photo) to clean-up the haul road thoroughly in order to avoid mud/slurry from escaping beyond the East Coast Road gate. The photos taken during the follow-up inspections and the wheel washing facilities layout plan were attached. The condition of site exit and the road section from wheel-washing facilities to East Coast Road gate was found to be improved and the situation was acceptable. Hence, the complaint was found non-related to Contract No. HY/2013/02. The complaint investigation report (Log No. 017) was provided in Appendix K.

 

2.       One complaint received by Environmental Protection Department on on 05 February 2018 and referred to the ENPO on 05 February 2018. Then the ENPO forwarded the complaint by email to the R.E. (AECOM), the Contractor (China Harbour) and the ET (ETS-Testconsult Ltd.) of Contract No. HY/2013/02 at 11:26 on 05 February 2018. The complaint detail was "®Ú¾Ú¡mªÅ®ð¦Ã¬VºÞ¨î(«Ø³y¤uµ{¹Ð®J)³W¨Ò¡n¦a½LÀ³¦b«ü©wªº¨®½ø¥X¤f³B¦w¸Ë½ü­L²M¬~³]¬I¦ý¨C¤é±ß¤W7ÂI«á´N·|³Q¦a½LºÞ²z¤H­ûºI¤ô¡A¨Ï©Ò¦³¨®½øµLªk¬~²M½ü­L¦Ó¨«¥X¤u¦a¡A¥O¦a­±°ï¿n¨F¹Ð¤Îªd¼ß¡A¼vÅT¨ä¥L¹D¸ô¨Ï¥ÎªÌ¤ÎÀô¹Ò½Ã¥Í¡C­n¨D·í§½¥[±j¨µ¬d¡A¥O¤u¦a¿í¦u³W¨Ò"

 

The complaint is under investigation during the reporting quarter and to be reported in the next reporting quarter.

 

Notifications of Summons and Successful Prosecutions

There were no notification of summon or prosecution received during the reporting period.

 

Reporting Change

Due to topographical conditions of SR3, SR10A and SR10B(N), the water quality monitoring (WQM) stations was proposed to be monitored at alternative WQM stations.

 

As such, proposal for alternation of water quality monitoring stations for HZMB HKBCF was justified by the ET Leader for Contract No. HY/2013/01 on 08 November 2017; verified by the IEC on 13 November 2017; and submitted to EPD on 29 November 2017, and it was approved by EPD on 22 December 2017.
