To achieve waste reduction	Contractor	Works area	Construction phase
S6.34 -S6.35	S5.7-5.8	General refuse: § General refuse should be stored in enclosed bins or compaction units separate from C&D material. A reputable waste collector should be employed by the contractor to remove general refuse from the site, separately from C&D material. Preferably an enclosed and covered area should be provided to reduce the occurrence of 'wind blown' light material. § In order to minimise impacts resulting from collection and transportation of C&D material for off-site disposal, the excavated materials arising from site formation and tunnel construction should be reused on-site as backfilling material and for landscaping works as far as practicable. In addition, volcanic rock generated from the tunnelling works should be subject to beneficial re-use. Other mitigation requirements are listed below: o A Waste Management Plan should be prepared o A recording system for the amount of wastes generated, recycled and disposed (including the disposal sites) should be used. o In order to monitor the disposal of C&D and solid wastes at public filling facilities and landfills, and to control fly-tipping, a trip-ticket system (e.g. ETWB TCW No. 31/2004) should be included.

Site investigation works should be carried out at Hong Kong School of Motoring (HKSM) site in accordance with the CAP. A Contamination Assessment Report (CAR) should be compiled after completing the SI works following the requirements in the CAP. The CAR should compare the findings with relevant standards and provide interpretation of the laboratory analysis. If land contamination is confirmed, a Remediation Action Plan (RAP) should be drawn up to formulate necessary remedial measures. The subsequent CAR and RAP should be endorsed by EPD before implementation of any remedial works. If the soil is contaminated with heavy metals or organic contaminants, the recommendation for handling such contaminated soil in the EIA should be followed. i.e. by biopiling (if TPH exceedance found in the SI) and/or cement solidification/stabilisation (if heavy metals exceedance found in the SI). Remediation treatment could be carried out at either Tai Shue Wan or the open space 100m away from the existing Nam Long Shan Road rest garden sites, or at both sites in an unlikely event that large volume of contaminated soil is identified. In the case that the heavy metal contaminated soil volume is small, treatment by CS/S could be conducted in the HKSM site. The soil treated by biopiling or CS/S should be finally re-used on-site as backfill materials.	To clean up any identified contaminated land where the ground will be disturbed by the proposed works.

S9.45-S9.46	S8.3	General Construction Activities: · Debris and refuse generated on-site should be collected, handled and disposed of properly to avoid entering any nearby water bodies and public drainage system. Stockpiles of cement and other construction materials should be kept covered when not being used. · Oils and fuels should only be used and stored in designated areas which have pollution prevention facilities. To prevent spillage of fuels and solvents to nearby water bodies and public drains, all fuel tanks and storage areas should 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. The bund should be drained of rainwater after a rain event.	To minimize water quality impacts	Contractor	Works area	Construction phase
S9.47		Sewage from Construction Workforce: · Temporary sanitary facilities, such as portable chemical toilets, should be employed on-site where necessary to handle sewage from the workforce. A licensed contractor would be responsible for appropriate disposal of waste matter and maintenance of these facilities.
