*Noise – Construction Phase*
4.7.1	1	· Avoid or reduce concurrent operation of construction equipment; · Use of quiet construction plant; · Use of site hoarding barriers ([1]) with a minimum height of 3m. In general, this would provide a minimum 10 dB(A) attenuation for the low-rise receivers. The barriers should not have openings or gaps and have a superficial surface density of at least 10 kgm^-2. The location and extent of the proposed barrier are shown in Figure 4.7a; · As a last resort, indirect mitigation measures in the form of window insulation and air-conditioning (air-conditioners have been provided for the staff quarters) are recommended to mitigate the residual noise impact. In general, this would provide a minimum 10 dB(A) attenuation for the receivers.	To minimise potential noise nuisance arising from the enabling works to CSD’s Staff Quarters (NSR N3).	During construction of enabling works near CSD’s Staff Quarters (NSR N3)	Construction contractor		ü			Noise Control Ordinance (NCO) and Annex 5 of the EIAO-TM
		· Close liaison with the CSD to programme the noisy construction works. Prior to commencement of the construction, CSD will be notified with the programme of the works, the planned construction activities, the potential impacts to the Staff Quarters, the measures to mitigate the impacts, the monitoring programme to check the efficiency of the measures, and the communication channels between CSD and the Site Engineer.
*Noise – Operational Phase*
4.7.2	2	A wind turbine with typical sound power level of 104 dB(A) with no tone, impulse and intermittence characteristics shall be adopted.	To minimise potential noise nuisance arising from operation of wind turbine.	During detailed design stage	CAPCO	ü		ü		Noise Control Ordinance (NCO) and Annex 5 of the EIAO-TM
4.8.2	3	During the operation phase, noise monitoring will be undertaken at the nearest NSR (ie Hei Ling Chau Addiction Treatment Centre (Annex) (N2)) during the night-time period at the agreed monitoring location to ensure the compliance with the stipulated noise criterion. As wind speed will vary throughout the year and hence the potential noise impact. It is recommended to monitor the noise levels at monthly intervals for first 12 months of the operation of the wind turbine. The monitoring frequency will be increased to biweekly intervals for the higher wind speed months (ie winter months (from December to January) and storm season (July)).	To ensure that adverse environmental impacts are prevented	At NSR N2 for the first 12 months of operation of the wind turbine	CAPCO			ü
*Ecology – Construction Phase*
5.10.2	4	To mimimise the loss of Common Rat Snake and Bodagek’s Burrowing Lizard due to the development of wind turbine, a search of the Common Rat Snake and Bodagek’s Burrowing Lizard within the Project Site and along the impacted sections of the Long and Short Access Routes will be conducted prior to the commencement of the construction works. Due to the small size of the Project Site and given that there are no optimal habitats for Common Rat Snake and Bodagek’s Burrowing Lizard, one day-time survey is considered sufficient. The impacted areas will be actively searched with special attention to the leave litters and rocks. All recorded Common Rat Snake and Bodagek’s Burrowing Lizard will be caught by hand and translocated to the shrubland at the north of the Hei Ling Chau Correctional Centre (Annex), which is the less disturbed shrubland habitat within the Study Area, immediately after the search. The search and the translocation (if required) will be undertaken by a qualified ecologist with relevant experience in faunal translocation works.

5.10.2	5	Construction Runoff: Storm water run-off from the construction sites will be directed into existing drainage channel via adequately designed sand/silt removal facilities such as sand traps, silt traps and sediment basins. Channels, earth bunds or sand bag barriers will be provided on site to properly direct storm water to such silt removal facilities.	To minimise potential ecological impacts arising from the works.	During construction phase for all construction work sites	Construction contractor		ü			Annex 16 of the EIAO-TM
5.10.2	6	Good Construction Practice: · Erect fences along the boundary of the Project Site before the commencement of works to prevent vehicle movements, and encroachment of personnel, onto adjacent areas; · Regularly check the work site boundaries to ensure that they are not breached and that damage does not occur to surrounding areas; and, · Reinstate temporary impacted area, immediately after completion of construction works.	To minimise potential ecological impacts arising from the works.	During construction phase	Construction contractor		ü			Annex 16 of the EIAO-TM
5.10.3	7	Some trees within the work areas of the proposed road upgrading works may need to be removed during construction. The actual number of trees affected will be determined in the Tree Survey during the detailed design. The impacted trees will either be transplanted or compensated by tree planting along the access routes or within the Project Site.	To compensate for the trees removed due to the construction works.	During construction phase	Construction contractor		ü			Annex 16 of the EIAO-TM
*Ecology – Operational Phase*
5.12.2	8	During the operation of the wind turbine, bird collision monitoring will be undertaken at monthly intervals for a period of 12 months. An area of 50m radius will be searched around the base of the wind turbine. If, after the 12-months monitoring period, insignificant number of bird collisions have been reported then the monitoring will be ceased.

To minimise the impact on the LRs.	Enabling works area and Project Site /during construction	Construction contractor		ü			Annexes 10 and 18 of EIAO-TM and EIAO Guidance Note 8/2002
6.4.10	10	There will be moderate to significant visual impact from the VSR of Hei Ling Chau among the eleven VSRs. Although the visual impact is unable to mitigate practically, the adverse effects are not considered too excessive in view of the size of landtake and form of the structure. Hence, the visual impact is not unacceptable. There are no significant visual impacts for other VSRs and there will be no interference with key views. Therefore, the landscape and visual impacts will be acceptable.
*Landscape and Visual – Operational Phase*
6.4.8 & 6.4.10	11	The impacts on landscape resource will mainly be associated with the construction phase. With the implementation of the recommended landscape mitigation measures, the long term impacts of the Project on landscape resource of Hei Ling Chau will be negligible. The Project Proponent will maintain the landscape mitigation measures (see EM&A Ref. Item no. 9) during the operation phase.	To minimise the impact on the LRs.
