Noise - Construction Phase

4.7.1

Good Site Practices

· Only well-maintained plant should be operated on-site and plant should be serviced regularly during the construction works;

· Machines and plant that may be use intermittently, such as vibratory poker, should be shut down between work periods or should be throttled down to a minimum;

· Plant known to emit noise strongly in one direction, should, where possible, be orientated to direct noise away from nearby NSRs; and

· Mobile plant should be sited as far away from NSRs as possible.

To minimise potential noise nuisance arising from the works to nearby NSRs.

Ecology – Construction Phase

5.11.2

Measures for Romer’s Tree Frog

· Undertake one day-time and one night-time survey for the Romer’s Tree Frog within the Project Area just before the construction works commence. The surveyor(s) should actively search within the Project Area paying special attention to the water bodies (ie abandoned containers). All recorded Romer’s Tree Frog (adults and tadpoles) must be caught by hand and translocated to the stream pools of middle course of Stream S4 near Lo Tik Wan, the critical natural habitat for the Romer’s Tree Frog within the Study Area, immediately after the survey. The Romer’s Tree Frog surveys and translocation works shall be undertaken by a qualified ecologist with at least five years of relevant experience in faunal translocation works.

5.11.2

Measures for Construction Runoff

· Surface run-off from the construction site should be directed into existing stream channel via adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins. Channels, earth bunds or sand bag barriers should be provided on site to properly direct stormwater to such silt removal facilities.

5.11.2

Good Construction Practice

· Erect fences along the boundary of the works area before the commencement of works to prevent tipping, vehicle movements, and encroachment of personnel onto adjacent areas.

· Avoid any damage and disturbance, particularly those caused by filling and illegal dumping, to the remaining and surrounding natural stream habitats.

· Regularly check the work site boundaries to ensure that they are not breached and that no damage occurs to surrounding areas.

· Prohibit and prevent open fires within the site boundary during construction and provide temporary fire fighting equipment in the Project Area.

· Treat any damage that may have occurred to individual major trees in the adjacent area and along the 275 kV Cable Route (used to transport the construction materials) with surgery.

· Reinstate temporary disturbed areas immediately after completion of the construction works, ie through on-site tree/shrub planting. Tree/shrub species used should make reference from those in the surrounding area and/or Annex C of EIA report.

Ecology – Operation Phase

5.11.3

No mitigation measures are required. See EM&A Manual for monitoring requirements.

Landscape and Visual – Construction Phase

6.7

· Colour scheme and non-reflective paints will be made to enable the proposed wind turbine to blend in well with natural surroundings and minimise the visual intrusion.

· Selection of low rotating speed machine to minimize the visual disturbance.

6.7

· New cut and fill slopes and other land affected by construction works would be reinstated to natural land form and topography of the natural slope as far as practical. Grading of these slopes to resemble a natural, rolling landform similar to that of adjacent topography would be carried out. Approximately 1,400 sq.m. of disturbed areas would be reinstated.

· Appropriate landscape planting including trees, shrubs and grasses (approx. 1,400 sq.m.) will be provided to soften the ground level appearance of the proposed wind turbine site.

· Existing soil resources on site from the cut slope will be re-used for backfilling at site as far as practicable to minimize the need to import or export soils.

No mitigation measures are required. See EM&A Manual for monitoring requirements.

Air Quality - Construction Phase

7.5.1

· Covering entirely by impervious sheet or frequently watering of the on-site stockpile of excavated materials to keep wet always before backfilling;

· Frequent watering of exposed area or worksite of excavation to maintain surface wet, if necessary and practical;

· Provision of vehicle washing to remove any dusting materials from small village trucks’ body and wheel at the exit of worksite;

· Well-maintained diesel-powered mechanical equipment to avoid black smoke emissions; and

· Shut-down of diesel-powered mechanical equipment or trucks inside the worksites when they are not in operation.

Surface Run-off

To minimise potential water quality impacts arising from the works

During construction

Construction Contractor

· Silt removal facilities should be maintained and the deposited silt and grit should be removed regularly, at the onset of and after each rainstorm to ensure that these facilities are functioning properly at all times.

· During excavation in the wet season, temporarily exposed soil surfaces should be covered, eg by tarpaulin, and temporary access roads should be protected by crushed stone or gravel, as excavation proceeds. Intercepting channels should be provided (eg along the crest/edge of the excavation) to prevent storm runoff from washing across exposed soil surfaces. Arrangements should always be in place to ensure that adequate surface protection measures can be safely carried out well before the arrival of a rainstorm.

· Earthworks final surfaces should be well compacted and the subsequent permanent work or surface protection should be carried out as soon as practical after the final surface are formed to prevent erosion caused by rainstorms. Appropriate intercepting channels should be provided where necessary. Rainwater pumped out from trenches or foundation excavations should be discharged into storm drains via silt removal facilities.

· Open stockpiles of construction materials (eg aggregates and sand) on site should be covered with tarpaulin similar fabric during rainstorms. Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system.

8.6.2

Wastewater from Site Facilities

· The use of chemical toilets will be necessary and these should be provided by a licensed contractor, who will be responsible for appropriate disposal and maintenance of these facilities.
