EXECUTIVE SUMMARY

The proposed widening of Tolo Highway and Fanling Highway between Island House Interchange and Fanling (the Project) is a Designated Project under the Environmental Impact Assessment Ordinance (Cap. 499) (EIAO). An Environmental Impact Assessment (EIA) Report (the approved EIA Report) together with an Environmental Monitoring and Audit (EM&A) Manual (the approved EM&A Manual) were completed and approved under the EIAO on 14 July 2000 (Register Number: EIA-043/2000).

The objective of the Project ¡°Widening of Tolo Highway / Fanling Highway between Island House Interchange and Fanling¡± is to widen Tolo Highway and Fanling Highway to dual 4-lane carriageway in order to alleviate the current traffic congestion problems and to cope with the increasing transport demands to and from the urban areas and also cross boundary traffic.

The construction works for this Project will be delivered in 2 stages i.e. Stage 1 (between Island House Interchange and Tai Hang) and Stage 2 (between Tai Hang and Wo Hop Shek Interchange).  Stage 2 would be implemented under two works contracts.  Contract No. HY2012/06 ¡°Widening of Fanling Highway ¨C Tai Hang to Wo Hop Shek Interchange¡± and the entrusted portion to CEDD under Contract No. CV/2012/09 ¡±Liantang/Heung Yuen Wai Boundary Control Point Site Formation and Infrastructure Works ¨C Contract 3¡±. This report focuses on Contract No. HY2012/06 ¡°Widening of Fanling Highway ¨C Tai Hang to Wo Hop Shek Interchange¡± in Stage 2 of the Project only.

Pursuant to the EP (EP-324/2008/A) Condition 2.7, the Capture Survey Trip Report for Ma Wat River Northern Meander (Version 2) for the Project was submitted on 24 December 2013 by the Environmental Team (ET) and verified by the Independent Environmental Checker (IEC) on 6 January 2014.

The construction phase of the Contract under the EP and the Environmental Monitoring and Audit (EM&A) programme of the contract commenced on 21 November 2013. The impact environmental monitoring and audit includes air quality and noise monitoring.

This report documents the findings of EM&A works conducted in the period between 1 November 2013 and 31 January 2014. As informed by the Contractor, construction activities in the reporting period were:-

-          Site clearance;

-          Ground investigation;

-          Construction of site accommodation;

-          Tree felling and transplantation; and

-          Erection of hoarding.

6             Summary of Exceedances of the Environmental Quality Performance Limit

6.1.1       All 1-hour and 24-hour TSP monitoring results complied with the Action / Limit Levels in the reporting quarter.

6.1.2       For construction noise, no Action and Limit Level exceedance was recorded at all monitoring stations in the reporting quarter.

 

7             Summary of Complaints, Notifications of Summons and Successful Prosecutions

7.1.1       One (1) noise-and-odour-related complaint was received on 19 December 2013 and followed up by the Environmental Team in December 2013. No notification of summons and successful prosecution was received in the reporting quarter. The statistics on complaints, notifications of summons and successful prosecutions are summarized in Appendix H.

7.1.2       EPD referred a complaint from Lot no. 116 of Fui Sha Wai at Tai Hang of Tai Po which is concerned about the construction noise and diesel-like smell generated from construction activities nearby which caused nuisance and health problems on 19 December 2013 morning.

According to the information of the Contractor (China State Construction Engineering (HK) Ltd.), ground investigation for site preparation work was carried out at the area near Fui Sha Wai at Tai Hang of Tai Po on 19 December 2013. The diesel-like smell was likely generated from the exhaust of drilling rig during operation.

Upon the receipt of complaint on 19 December 2013, the Contractor met the complainant to discuss for improvement measures to be taken for the works on the same day. The Contractor subsequently extended the exhaust duct of the drilling rig to a higher position for achieving a better gas dispersion and hence to reduce the impact to the public on 20 December 2013.

 

The Contractor is willing to defer the operation time of the drilling rig to later time in the morning to minimize nuisance caused to the public.

 

The noise and odour nuisance complaint is considered project-related.

 

7.1.3       A 24-hour complaint hotline at 6628 8366 has been established for the Project. The hotline number is displayed at the site entrances, fencings and project signboards, as well as printed on publications such as newsletters for the public.

8             Comments, recommendations and Conclusions

8.1          Comments

8.1.1       According to the environmental site inspections performed in the reporting quarter, the following recommendations are provided to the Contractor for precautionary and rectification purposes:

Air Quality Impact

l  All vehicles should be washed to remove any dusty materials before leaving the site.

l  Haul roads should be sufficiently dampened to minimize fugitive dust generation.

l  Wheel washing facilities should be properly maintained to ensure properly functioning.

Construction Noise Impact

l  Noisy operations should be oriented to a direction away from sensitive receivers as far as possible.

Water Quality Impact

l  Stagnant water accumulated in drip trays should be removed.

l  Silt accumulated at the public drain should be cleaned up.

l  Silty effluent should be treated/desilted before being discharged. Untreated effluent should be prevented from entering the public drain channel.

Chemical and Waste Management

l  C&D materials should be sorted and removed timely.

l  All plants on site should be properly maintained to prevent oil leakage.

l  Oil stains on soil surfaces and empty chemical containers should be cleared and disposed of as chemical waste.

Landscape and Visual Impact

l  All retained trees should be properly fenced off at the works area.

 

8.2          Recommendations

8.2.1       The impact air quality and noise monitoring programme ensures that any deterioration in environmental condition is readily detected and timely actions are taken to rectify any non-compliances. Assessment and analysis of monitoring results collected demonstrated the environmental acceptability of the Project. The weekly environmental site inspections ensure that all the environmental mitigation measures recommended in the ERR are effectively implemented.

8.2.2       The EM&A programme effectively monitored the environmental impacts from the construction activities and no particular recommendations were advised for the improvement of the programme.

8.3          Conclusions

8.3.1       All 1-hour and 24-hour TSP monitoring results complied with the Action / Limit Levels in the reporting quarter. No Action and Limit Level exceedances for construction noise were recorded at all monitoring stations in the reporting quarter.

8.3.2       One (1) noise-and-odour-related complaint was received, and no notification of summons and successful prosecution was received in the reporting month.
