a. Temporary open storage of excavated materials shall be covered with tarpaulin or similar fabric during rainstorms. Any washout of construction or excavated materials from the drill-and-blast tunneling work shall be diverted to the drainage system via appropriate sediment traps, to achieve a controlled release of storm flow, construction runoff, or wash water.

b. Ground water pumped out of tunnels shall be discharged into sediment traps to enhance deposition rates and to remove silt, before discharging into the drainage channels of the drainage system.

3.3 To mitigate environmental impacts due to site runoff and other potential water pollution caused by construction activities, mitigation measures described in Annex B shall be fully implemented throughout the construction period.

3.4 To mitigate ecological impact during construction, the following measures shall be fully implemented:

Environmental Permit No. EP-104/2001/C

Annex A (extracted from the Application VEP-238/2007, and as referred to in Condition 3.1)

Sound absorptive panels are used at the lower portion of the noise barrier (i.e. up to 2m above carriageway level) and transparent panels are used at the upper portion of the barriers, except the 3m high noise barrier outside Tin Sam Village as shown in Figure 2. For this 3m high noise barrier transparent panels are used for full height of the noise barrier. A summary of the mitigation measures are given below, where “left side” and “right side” are taken to mean the respective sides for a person driving along the designated direction of the carriageway:

Fo For main road
· A full enclosure of up to approx. 375m long, located along the main road of Route 9 facing the MOS depot development, to join at the north with the underpass for the Trunk Road T3 as one continuous enclosure;

· At the south portal of the full enclosure, a 5.5m minimum high with 4m cantilever barrier, i.e. NB2 (as shown in Figure 2) along the left side of the northbound carriageway and a 5.4m minimum high with 4m cantilever barrier, i.e. NB3 (as shown in Figure 2) along the right side of southbound carriageway. The height is increased near the full enclosure to keep the variable speed limit sign mounted on the external wall of the RC Full Enclosure visible by the northbound vehicles during both the normal and bi-directional traffic flow ;

·Low Noise Road Surfacing (LNRS) on the Route 9 main alignment.

For slip roads

· A minor full enclosure of approx. 83 meters long, located near the middle of the north and south-bound slip roads leading from the Route 9 main alignment to Che Kung Miu Road.

Northbound slip road

Left side

· A 5.5m minimum high with 4m cantilever barrier of approx. 380m long, i.e. NB1 (as shown in Figure 2) running from the left side of the northbound carriageway of the main road, to join the west end of the minor enclosure on the slip road; a 5m high vertical barrier originated from the east end of the minor enclosure, running for approx. 120m to join a 5.5m minimum high with 4m cantilever barrier of approx. 240m long, i.e. NB5A (as shown in Figure 2). The height of the noise barrier near the North Portal Building is increased to 7.5m high with 4m cantilever barrier follow by 92m transition to keep the lane control signal mounted on the facade of the North Portal Building visible by the southbound vehicles during bi-directional traffic flow and to prevent the obstruction by the cantilever portion of the noise barrier during the operation of the CCTV mounted on a nearby sign gantry.

Northbound slip road

Right side

· An approx. 100m long 3m high vertical barrier, i.e. NB11 (as shown in Figure 2) joining the west end of the minor enclosure, followed by a 3m high vertical barrier of approx. 200m long, i.e. NB7 (as shown in Figure 2) running from the east end of the minor enclosure towards Che Kung Miu Road; a separated 3m high vertical barrier of approx. 160m long, i.e. NB8 (as shown in Figure 2) is also to be provided on the split section of the slip road at this end of the Che Kung Miu Road; it is then followed by an approx. 160m long 1.5m high crash barrier.

Southbound slip road

Left side

· From Che Kung Miu Road, a 3m high vertical barrier of approx. 160m, i.e. NB6 (as shown in Figure 2) followed by a 5m high vertical barrier of approx. 265m long running, i.e. NB10 (as shown in Figure 2) along the left side until the minor enclosure is reached; followed by a 5.5m minimum high with 4m cantilever barrier of approx. 350m, i.e. NB4 (as shown in Figure 2) from the west end of the minor enclosure towards the Route 9 main alignment. The heights of the noise barriers are increased (about 400mm) locally due to the change of the road profile and the contractor’s proposed fixing arrangement for panels’ installation at the cantilever portion of the noise barrier posts.

Southbound slip road

Right side
· From the west end of the minor enclosure, a 5m high vertical barrier of approx. 170m long, i.e. NB5 (as shown in Figure 2) running towards the Route 9 main alignment. From the Che Kung Miu Road end of the slip road, an approx. 135m long 5.5m minimum high with 2m cantilever barrier, i.e. NB9 (as shown in Figure 2) is to be provided for the left lane of the split section of the slip road.

Annex B (as referred to in Condition 3.3)

Measures to Mitigate Environmental Impacts due to Site Run-off and Other Potential Water Pollution During Construction

(a) Surface Runoff

(i) Surface run-off from the construction site shall be directed into adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins before discharge into storm drains. Channels, earth bunds or sand bag barriers shall be provided on site to properly direct stormwater to such silt removal facilities.

(ii) Catchpits and perimeter channels shall be constructed in advance of site formation works and earthworks.

(iii) Silt removal facilities, channels and manholes shall be suitably maintained with the deposited silt and grit being removed at least once a week, and at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.

(iv) Earthworks final surfaces shall be well compacted and the subsequent permanent work or surface protection shall be carried out immediately after the final surfaces are formed to prevent erosion caused by rainstorms. Appropriate intercepting channels shall be provided along the site boundary or at the locations agreed with the ET Leader. Rainwater pumped out from trenches or foundation excavations shall be discharged into silt removal facilities before discharge into storm drains.

(v) All generators, fuel and oil storage shall be within bunded areas. Drainage from the areas shall be connected to storm drains via a petrol interceptor.

(vi) Sand and silt in the wash water from the wheel washing facilities, which ensure no earth, mud and debris are deposited on roads, shall be settled out and removed before discharging into storm drains. A section of the road between the wheel washing bay and the public road shall be paved with backfill to prevent wash water or other site runoff from entering public road drains.

(vii) Oil interceptors shall be provided in the drainage system and regularly emptied to prevent the release of oils 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.

(b) General Construction Activities

At all parts of all works areas and construction sites, and throughout the full duration of the construction contract(s), debris and rubbish on site shall be handled and disposed of to avoid entering the water column and causing water quality impacts. Temporary on-site storage of excavated materials from construction works shall be covered with tarpaulin or similar fabric during rainstorms. Any washout of construction or excavated materials should be diverted to the drainage system via sediment traps. Stockpiling of the excavated material shall be minimized by scheduling the construction programme in a way that one section of the alignment can be constructed and completed before the excavation works of the next section commence.
