Appendix A

 

Measures to Mitigate Environmental Impacts from Site Runoff and Drainage during Construction

 

The following shall be implemented at all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s):-

 

(a)           Perimeter channels to intercept storm runoff from outside of the site.  These should be constructed in advance of earth works;

 

(b)           Sand/silt removal facilities such as sand traps, silt traps and sediment basins and regular maintenance of these facilities to ensure proper functioning and efficient operation at all times.  The design of silt removal facilities should be based on the guidelines in ProPECC Practice Note 1/94 issued by the Director;

 

(c)           Careful programming of the works to minimize soil excavation works during rainy seasons (April to September).  If excavation of soil cannot be avoided during the rainy season, or at any time of year when rainstorms are likely, exposed slope surfaces should be covered with tarpaulin or other effective means;

 

(d)           Open stockpiles of construction materials on site be covered with tarpaulin or similar fabric during rainstorms;

 

(e)           Dikes or embankments for flood protection around the boundaries of earthwork areas;

 

(f)            All fuel/oil tanks and chemical storage tanks/areas be provided with locks and be sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity of the largest tank, to prevent spilled fuel oils from reaching the receiving water bodies;

 

(g)           Wheel washing facilities at each of the site entrance and regular maintenance of these facilities to ensure proper functioning and efficient operation at all times;

 

(h)           Oil interceptors be provided in the drainage system downstream of any oil/fuel pollution sources associated with construction.  Regular maintenance of the oil interceptors to prevent the release of oil and grease into the storm water drainage system after accidental spillage.  The interceptor shall have a bypass to prevent flushing during periods of heavy rain.

 

(i)             Temporary and permanent drainage pipes and culverts be provided to facilitate runoff discharge.  The temporary and permanent drainage pipes and culvert be adequately designed for the controlled release of storm flows.  All these measures be regularly inspected and maintained to ensure good working conditions at all times and particularly following rainstorms.  Temporarily diverted drainage be reinstated to its original condition when construction works has finished or the temporary diversion is no longer required; and

 

Portable chemical toilets and sewage holding tanks by a licensed contractor to handle the construction sewage generated by workers from both the construction areas and dispersed along the alignment.  Regular waste disposal and maintenance of these facilities by a licensed contractor to ensure proper functioning.


Appendix B

 

Measures to Mitigate Environmental Impacts from Construction Noise

 

 

The construction programme should be scheduled to avoid overlapping of construction work of the Project with that of the West Rail within the site boundary of the Project as to minimize cumulative impact.

 

Throughout the construction period of the Project, mitigation measures for specific construction activities at specific locations shall be implemented in accordance with Table 7.9 of the EIA Report.  Corresponding mitigation measures for each construction activity to result in the lowest worst case maximum cumulative construction noise level indicated in Table 7.9 the EIA Report during each construction phase shall be used.  Mitigation measures M1 to M4 the table are defined as follows:-

 

M1:     Use of Quiet Plant and Working Methods

 

Throughout the full duration of the construction contract(s), models of plant which comply with the BS 5228 Part 1 or EPD’s “Technical Memorandum on Noise from Construction Work in Designated Areas” shall be used.

 

M2:            Temporary and Movable Noise Barriers

 

Throughout the full duration of the construction contract(s), hoarding(s) of height 3-5 metres along the site boundary and temporary purpose built or movable noise barrier(s) shall be provided within a few metres of stationary plant (air compressor, water pump, concrete pump, generator, poker vibrator, etc.) and within about 5 m of mobile equipment (excavator, lorry, roller, dump truck, concrete lorry mixer and mobile cranes, etc.) such that the line of sight is blocked by the barriers viewed from the noise sensitive receivers (NSRs).  Where high-rise Noise Sensitive Receivers (over 5 storeys) may be affected, the use of cantilevered top cover(s) shall be provided, whenever practicable.  The surface density of the barrier(s) / hoarding(s) shall not be less than 7kg/m2

 

M3:        Delocalization of Equipment in Critical Areas and Reducing the Number of Plant Operating in Critical Areas Close to NSRs

 

The number of items of plant operating at the same time at the specified locations shall be minimized for each construction activity.

 

M4:     Limiting Operation Time of Construction Equipment On-Site

 

When carrying out site clearance and formation works near the TWGH’s Kwok Yat Wai College and when carrying out track laying works near the Tin Shui Wai Catholic Primary School, the operation time of dump trucks at the vicinity is reduced to less than 15 minutes within any 30-minute interval.

 

 

 

 

 


Appendix C

 

Measures to Mitigate Environmental Impacts from Landscape and Visual during Construction

 

 

At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), the following mitigation measures shall be implemented:-

 

(a)           Any topsoil encountered during construction should be carefully stockpiled and provision be made for its reuse in suitable planting areas;

 

(b)           Use of 3-5 metre high hoarding(s) at the perimeter of the designated LRT reserve to screen the majority of the work site from view; and

 

(c)           Tree and shrub planting within the railway reserve to soften the visual impact of the viaduct, and make use of climbing plants to soften the appearance of viaduct column as per the approved Landscape Master Plan(s).

 

 

 

 


Appendix D

 

Measures to Mitigate Environmental Impacts from Site Runoff and Drainage during Operation

 

To mitigate the environmental impacts from site runoff and drainage during the operational phase, the following shall be implemented:

 

(a)      A surface water drainage system shall be provided to collect the track runoff.  Where oil and lubricating fluids can be spilt, the tract drainage channels discharge shall pass through oil/grit interceptors/chambers, or a sub-soil drainage system to remove oil, grease and sediment before being pumped to the public stormwater drainage system.

 

(b)      Silt traps and oil interceptors shall be cleaned and maintained regularly to ensure proper functioning and efficient operation.

 

(c)      Oily contents of the oil interceptors shall be transferred to an appropriate disposal facility, or to be collected for reuse, if possible.
