6              CONCLUSIONS AND RECOMMENDATIONS

Conclusions

6.1         This Quarterly Environmental Monitoring and Audit (EM&A) Report presents the EM&A works undertaken in the period between June to August 2018 in accordance with EM&A Manual. 

 

6.2         No Action/Limit Level exceedance was recorded for air quality and noise.

6.3         There are nineteen Action Level exceedances were recorded for suspended solids. No Action/Limit Level exceedance for dissolved oxygen and turbidity was recorded in the reporting period.

6.4         According to the investigation, all exceedances are considered not due to the Contract.

 

6.5         No Action/Limit Level exceedance of dolphin monitoring for the quarterly monitoring data.

6.6         During this quarter of dolphin monitoring, no adverse impact from the activities of the HKLR09 construction project on Chinese White Dolphins was noticeable from general observations.

 

6.7         Environmental site inspection was conducted on 5th, 12th, 19th and 26th June 2018, 3rd, 10th, 17th, 24th and 31st July 2018, 7th, 14th, 21st and 28th August 2018by ET in the reporting month. All deficiencies identified during the site inspection have already rectified / improved during the follow-up audit session.

 

6.8         The inspection to the Sha Lo Wan (West) Archaeological Site was conducted on 19th June 2018. No access to Sha Lo Wan (West) Archaeological site for works areas and storage of construction equipment was observed.

                                                                                                                      

6.9         There was no environmental complaint received in the reporting period. No notification of summons and successful prosecution received in the reporting period.

 

6.10     The ET will keep track on the EM&A programme to ensure compliance of environmental requirements and the proper implementation of all necessary mitigation measures.

Recommendations

 

6.11     According to the environmental audit performed in the reporting month, the following recommendations were made:

 

Air Quality Impact

 

¡P          To regularly maintain the quality of machinery and vehicles on site.

¡P          To implement dust suppression measures on all haul roads, stockpiles, dry surfaces and excavation works.

¡P          To provide hoarding along the entire length of that portion of the site boundary.

 

 

Noise Impact

 

¡P          To inspect the noise sources inside the site.

¡P          To space out noisy equipment and position the equipment as far away as possible from sensitive receivers.

¡P          To provide temporary noise barriers for operations of noisy equipment near the noise sensitive receivers, if necessary.

 

Water Impact

 

¡P     To prevent any surface runoff discharge into any stream course and sea.

¡P     To review and implement temporary drainage system.

¡P     To identify any wastewater discharges from site.

¡P     To ensure properly maintenance for de-silting facilities.

¡P     To clear the silt and sediment in the sedimentation tanks.

¡P     To review the capacity of de-silting facilities for discharge.

¡P     To divert all the water generated from construction site to de-silting facilities with enough handling capacity before discharge.

¡P     To avoid accumulation of stagnant and ponding water on site.

 

Ecology Impact

¡P     To implement Spill Response Plan in the event of accidential spillage of or other hazardours chemicals.

¡P     To implement Dolphin Exclusion Zone during the installation of bored pile casing located in the waters to the west of Airport.

¡P     To implement Dolphin Watching Plan after the bored piling casing is installed.

¡P     To ensure the acoustically-decoupled measures were implemented for air compressors and other noisy equipment mounted on construction vessels according to acoustic decoupling measures plan. 

 

Waste/Chemical Management

 

¡P          To check for any accumulation of waste materials or rubbish on site.

¡P          To ensure the performance of sorting of C&D materials at source (during generation);

¡P          To carry out inspection of dump truck at site exit to ensure inert and non-inert C&D materials are properly segregated before removing off site.

¡P          To avoid any discharge or accidental spillage of chemical waste or oil directly from the site.

¡P          To avoid improper handling or storage of oil drum on site.
