Follow-up action to the complaint received by Highways Department on 29 December 2017 and referred to the ENPO on 08 January 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 12:20 on 08 January 2018. 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.

W1

Mitigation during the marine works to reduce impacts to within acceptable levels have been recommended and will comprise a series of measures that restrict the method and sequencing of dredging/backfilling, as well as protection measures. Details of the measures are provided below:

-          No dredging works of marine sediment shall be carried out the Project except for the construction of box culverts and seawalls at Portion D.

-          Reclamation filling for the Project shall not proceed until at least 200m of leading seawall at the reclamation area formed above +2.2mPD, unless otherwise agreement was obtained from EPD, except for the 300m gaps for marine access. All underwater filling works shall be carried out behind seawalls to avoid dispersion of suspended solids outside the Project limit;

-          Except for the filling of the cellular structures, not more than 15% public fill shall be used for reclamation filling below +2.5mPD during construction of the seawall;

-          After the seawall is completed except for the 300m marine access as indicated in the EPs, not more than 30% public fill shall be used for reclamation filling below +2.5mPD, unless otherwise agreement from EPD was obtained;

-          No more than 2 grab dredgers with a maximum daily dredging rate of 12,000m3 shall be employed for dredging operation at Portion D of the Project;

-          Upon completion of 200m leading seawall, no more than a total of 60 filling barge trips per day shall be made with a cumulative maximum daily filling rate of 60,000 m3 for HKBCF and TMCLKL southern landfall reclamation during the filling operation; and

-          Upon completion of the whole section of seawall except for the 300m marine access as indicated in the EPs, no more than a total of 190 filling barge trips per day shall be made with a cumulative maximum daily filling rate of 190,000 m3 for the remaining filling operations for HKBCF and TMCLKL southern landfall reclamation.

-          Closed grabs should be used for sediment dredging to reduce sediment loss when lifting the grabs to the barges. Only grab dredgers shall be used for dredging works of the Project;

-          All mechanical grabs shall be designed and maintained to avoid spillage;

-          The moving speed of construction vessels in the dredging area should be reduced to prevent disturbance to the seabed generating sediment plumes;

-          Floating type silt curtains shall be installed enclosing the entire reclamation site at all time. Staggered layers of silt curtain shall be provided to prevent sediment loss at navigation accesses. The length of each staggered layers shall be at least 200m;

-          The cage-type silt-curtain with steel enclosure is proposed to be installed to enclose local pollution caused by the grab dredging. The grab dredging work should be carried out within the cage-type silt curtain;

-          Single layer silt curtain to be applied around the North-east airport water intake;

-          The silt-curtains should be maintained in good condition to ensure the sediment plume generated from dredging and filling be confined effectively within the site boundary;

-          The dredging and filling works shall be scheduled to spread the works evenly over a working day;

-          Cellular structure shall be used for seawall construction;

-          A layer of geotextile shall be placed on top of the seabed before any filling activities take place inside the cellular structures to form the seawall;

-          The conveyor belts shall be fitted with windboards and conveyor release points shall be covered with curtain to prevent any spillage of filling materials onto the surrounding waters;

-          An additional layer of slit curtain shall be installed near the active stone column installation points. A layer of geotextile with stone blanket on top shall be placed on the seabed prior to stone column installation works. Stone blanket -> with silt curtain.

-          manholes (including any newly constructed ones) should always be adequately covered and temporarily sealed so as to prevent silt, construction materials or debris from getting into the drainage system, and to prevent storm run-off from getting into foul sewers;

-          discharges of surface run-off into foul sewers must always be prevented in order not to unduly overload the foul sewerage system;

-          all vehicles and plant should be cleaned before they leave the construction site to ensure that no earth, mud or debris is deposited by them on roads. A wheel washing bay should be provided at every site exit;

-          wheel wash overflow shall be directed to silt removal facilities before being discharged to the storm drain;

-          the section of construction road between the wheel washing bay and the public road should be surfaced with crushed stone or coarse gravel;

-          wastewater generated from concreting, plastering, internal decoration, cleaning work and other similar activities, shall be screened to remove large objects;

-          vehicle and plant servicing areas, vehicle wash bays and lubrication facilities shall be located under roofed areas. The drainage in these covered areas shall be connected to foul sewers via a petrol interceptor in accordance with the requirements of the WPCO or collected for off site disposal;

-          the contractors shall prepare an oil / chemical cleanup plan and ensure that leakages or spillages are contained and cleaned up immediately;

-          waste oil should be collected and stored for recycling or disposal, in accordance with the Waste Disposal Ordinance;

-          all fuel tanks and chemical storage areas should be provided with locks and be sited on sealed areas. The storage areas should be surrounded by bunds with a capacity equal to 110% of the storage capacity of the largest tank; and

-          surface run-off from bunded areas should pass through oil/grease traps prior to discharge to the stormwater system.
