EXECUTIVE SUMMARY

 

i.      This is the Thirty Second Monthly Environmental Monitoring Audit (EM&A) Monthly Report – December 2016 for Contract No. CV/2013/04 – Dredging Works in Kwai Tsing and its Approach Channel (Agreement No. CE63/2008 – Providing Sufficient Water Depth for Kwai Tsing Container Basin and its Approach Channel). The dredging works commenced on 23 April 2014. This report presents the environmental monitoring and audit works conducted from 23 November 2016 to 22 December 2016.

 

ii.    Construction Activities for the Reporting Period

According to the works programme provided by Contractor, the construction work under this Contract has been temporarily suspended since 13 August 2016.   During this period, there is no dredging work under this project. Marine construction works will be resumed on 24 December 2016.

 

iii.   Water Quality Monitoring

Routine impact water quality monitoring was temporarily suspended since 1 September 2016 according to Clause 2.1.6 of the EM&A Manual and the Proposal for Temporary Suspension of Water Quality Monitoring (0394_13_ED_0326F) which no objection was received from EPD. Routine impact water quality monitoring will be resumed on 24 December 2016.

 

24-hr water quality monitoring was conducted at 7 of the stations, which are SR4, SR5, SR9, SR10, SR11, SR12 and SR13. No exceedance was recorded in the reporting month. Number of exceedances recorded in the reporting month at each impact station is summarized in Table I.

No inert or non-inert C&D material related to dredging works was disposed and a small amount of general refuse were disposed off site in the reporting month.

 

v.    Non-Compliance, Complaints, Notifications of Summons and Successful Prosecutions

No complaint, notification of prosecutions or summons was received in the reporting period.

 

vi.   Site Inspections and Audit

The Environmental Team conducted 5 site inspections in the reporting period. No particular observation was recorded in the reporting month except Contractor was reminded to place the corrected NRMM labels for the two air compressors on the drilling barge 998.

 

vii.  Compliance with Specific EP conditions

Implementation of contractor’s mitigation for waste management and other general site practice were checked. It was concluded that the project in compliance with the EP requirements on site mitigation measures in general.

 

viii.Construction Activities for the Coming Reporting Period

According to the work programme provided by the Contractor, the construction work under this Contract has been temporarily suspended since 13 August 2016.  Marine construction works will be resumed on 24 December 2016 

 

During the coming reporting period, the principal work activities included:

·                     Preparation Works of Dredging at Portion A / Zone 2B1, 2B2 and  Zone 2C1 in EP

·                     Dredging at Portion A / Zone 2B1, 2B2 and  Zone 2C1 in EP

 

Future Key Issues include:

·                     Regular inspection on silt curtain deployment

·                     Regular inspection on silt screen deployment

·                     Implementation of EM&A Programme

·                     Maintain dredging below allowable dredging rate in EP.

·         Cleaning of excess material from the decks and exposed fittings of barges and dredgers before the vessel is moved.

·                     Barge loading shall be monitored to ensure material is not lost during transportation.

·                     Conditions in dumping permit shall be followed strictly.
