Environmental Complaint

ES05            In this Reporting Period, two (2) documented environmental complaint was received and lodged for Contracts 6 regarding construction dust and muddy water discharge on 1 and 16 December 2015 respectively.  Follow up actions have been undertaking by the Contractor to resolve the deficiencies and investigation report conducted by ET had submitted to all relevant parties.

 

Notification of Summons and Successful Prosecutions

ES06            No environmental summons or successful prosecutions were recorded in the Reporting Period.

 

Reporting Change

ES07            No reporting changes were made in the Reporting Period.

 

Site Inspection

ES08            In this Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 2 has been carried out by the RE, IEC, ET and the Contractor on 4, 11, 18, 23 and 30 December 2015.  No non-compliance was noted.

 

ES09            In the Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 3 has been carried out by the RE, IEC, ET and the Contractor on 7, 16, 21 and 28 December 2015.  No non-compliance was noted.

 

ES10            In the Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 5 has been carried out by the RE, IEC, ET and the Contractor on 3, 10, 16, 24 and 31 December 2015.  No non-compliance was noted.

 

ES11            In the Reporting Period, joint site inspection to evaluate the site environmental performance at Contract 6 has been carried out by the RE, IEC, ET and the Contractor on 3, 10, 17, 23 and 30 December 2015.  No non-compliance was noted.

Future Key Issues

ES13            During dry season, special attention should be paid on the potential construction dust impact since most of the construction sites are adjacent to villages. The Contractor should fully implement the construction dust mitigation measures properly.

 

ES14            The Contractor was also reminded to prevent muddy water or other water pollutants from site surface flow to local stream such as Kong Yiu Channel, Ma Wat Channel, Ping Yuen River or public area.  Water quality mitigation measures to prevent surface runoff into nearby water bodies or public areas should paid attention and fully implemented.  

 

ES15            Construction noise would be a key environmental issue during construction work of the Project.  Noise mitigation measures such as using quiet plants should be implemented in accordance with the EM&A requirement.

3                    Summary of Impact Monitoring Requirements

3.1              General

3.1.1                 The Environmental Monitoring and Audit requirements are set out in the Approved EM&A manual. Environmental issues such as air quality, construction noise and water quality were identified as the key issues during the construction phase of the Project.

 

3.1.2                 A summary of construction phase EM&A requirements are presented in the sub-sections below.

 

3.2              Monitoring Parameters

3.2.1                 The EM&A program of construction phase monitoring shall cover the following environmental issues:

                     Air quality;

                     Construction noise; and

                     Water quality

 

3.2.2                 A summary of the monitoring parameters is presented in Table 3-1.

Table 3-1         Summary of EM&A Requirements

Environmental Issue

Parameters

Air Quality

Ÿ  1-hour TSP by Real-Time Portable Dust Meter; and

Ÿ  24-hour TSP by High Volume Air Sampler.

Noise

Ÿ  Leq(30min) in normal working days (Monday to Saturday) 07:00-19:00 except public holiday; and

Ÿ  3 sets of consecutive Leq(5min) on restricted hours i.e. 19:00 to 07:00 next day, and whole day of public holiday or Sunday

Ÿ  Supplementary information for data auditing, statistical results such as L10 and L90 shall also be obtained for reference.

Water Quality

In-situ Measurements

Ÿ  Dissolved Oxygen Concentration (mg/L);

Ÿ  Dissolved Oxygen Saturation (% );

Ÿ  Turbidity (NTU);

Ÿ  pH unit;

Ÿ  Water depth (m); and
