4.0 WASTE MANAGEMENT HIERARCHY

(i) DBJV will adapt a surplus material management hierarchy throughout the works. The management options can be categorized in terms of preference from an environmental viewpoint. The options considered preferable will have the least impacts and are more sustainable in the long term.

Hierarchical Level	Method	Measures
Level 1 - Preferred	Elimination	Waste reduction has been considered in the pre-tender phases of project development. An optimal level has been achieved, considering the level of technology at hand. Further elimination of wastes could be achieved by means of alternative design and methods, proposed by the Contractor.
Level 2	Reduction at Source	Where the amount of wastes cannot be eliminated by design and methodology, wastes may be minimized by means of controlling the production/manufacturing processes at source. For example, pre-casting of concrete segments at factories will be more effective than in-situ concreting methods. To achieve this level of achievement, construction methodologies must be planned in advance to enable to utilize preferred component procurement channels. Significant engineering control is needed.
Level 3	Recycling	Further to the elimination and reduction processes, additional engineering and/or subletting approaches will be considered to recycle and reuse materials as far as practicable, without substantial treatment. Waste buyback or return arrangements may be agreed with suppliers. Otherwise, useful materials/commodities may be resold for reprocessing and reuse.
Level 4	Treatment	Where materials cannot be directly recycled or reused, additional engineering methods will be employed to treat waste materials, as far as practicable, so that they may be recycled or reused. For example, slurry treatment plant will allow water and bentonite slurry to be recycled and reused for the TBM tunneling works. Also, slurry treatment will stabilize the excavated C&D export materials for disposal, potentially enabling the materials to be reused on site or disposed at public fills, rather than at marine mud pits or landfills.
Level 5 – Not Preferred	Disposal	Only where materials cannot be managed by the above methods, shall they be removed directly to dumping, in accordance with methods compliant with statutory and contract requirements.

11.2 On-site Sorting of C&D Materials

(i) A system for on-site sorting of C&D materials would be devised, including the identification of the source of generation, estimated quantity, arrangement for on-site sorting and/or collection, temporary storage areas, frequency of collection by recycling contractors or frequency of removal off Site, etc.

(ii) The design of onsite sorting facilities is illustrated in Appendix F. The area is approximately 7m x 10m which is enough for onsite sorting of waste. The proposed onsite sorting facilities will be placed far away from the drainage of surface runoff, to reduce the chance of contamination. It is next to the location of storage area for C&D materials, in order to minimize the environmental effect during the transportation of C&D waste (e.g. dust generation, waterway contamination). The C&D waste will be sorted in inert and non-inert waste, and differentiate with recyclable material. Different waste receptacles will be labelled with suitable logos and provided as in the site layout plan for onsite sorting purpose. The location of on-site sorting facilities is presented in Appendix F.

(iii) Sorting the materials at source into:

· hard rock and large broken concrete suitable for reuse on the Site or recycling at a designated location;

· metals;

· paper and plastics;

· chemical waste; and

· materials suitable for disposal at public fill reception facilities, sorting facilities and landfills/outlying islands transfer facilities. Disposal at the sorting facilities should first be approved by the SOR.

(iv) Except for those inert C&D materials to be reused on Site, all other C&D materials shall be removed off the Site as soon as practicable in order to optimize the use of the on-site storage space. DBJV shall identify and provide sufficient space for temporary storage of C&D materials to facilitate collection and/or sorting on the Site;

(v) Arrangements with potential recycling contractors shall be made to facilitate that recyclable materials sorted from the Site are collected with reasonable care;

(vi) A system shall be established for proper handling and storage of chemical waste generated from the Site, and arrange for the collection and disposal of such chemical waste by specialist contractors. The location of storage of chemical waste is also demonstrated in Appendix F.

11.3 Waste Flow Table (WFT)

(i) A mechanism to record the quantities of C&D materials generated each month shall be established, using the monthly summary “Waste Flow Table” as in Appendix G. The monthly summary WFT shall be completed by Environmental Officer and submitted to the SOR or his representative together with the updated sections of EMP (if any) by not later than 15^th day of each month following the month reported on, or if it is a General Holiday, the day following the General Holiday;

(ii) The latest estimate of the total amount of C&D materials shall also be submitted including rock, that are expected to be generated by the Works, together with a breakdown of the nature of the materials (i.e. inert C&D materials (public fill), hard rock or concrete, C&D waste, etc.). Such information should be submitted together with the monthly summary “Waste Flow Table” as required above.

11.4 Control of the Use of Timber

(i) The use of timber in temporary works construction should be avoided, reduced or minimized as far as possible. Where the use of timber for a temporary works construction process/activity with an estimated quantity exceeding 300m³, a method statement should be submitted to the SOR for agreement prior to commencement of the relevant temporary works. The method statement should include the justification for and the measures taken to minimize the use of timber in the said temporary works;

(ii) In addition, a summary table should be provided containing the description, justification and the estimated quantity for every work process/activity requiring the use of timber for temporary works construction irrespective of the quantity of timber used. It should be updated and submitted to the SOR or his representative together with the monthly summary WFT for monitoring and review by not later than 15^th day of each month, or if it is a General Holiday, the day following the General Holiday. DBJV shall draw the attention of the SOR or his representative to those work processes/activities for which the estimated quantities have been revised.

11.5 Recyclable Materials

(i) Control measures would be devised to ensure that the recyclable materials are delivered to a proper recycling outlet for processing, and to avoid such materials being considered as C&D materials for the purposes of the Contract. Trip ticket system is not applicable to recyclable materials. However, the invoice, receipt or disposal records will form parts of the comprehensive register as described in the previous section to ensure integrity of disposal records. The monthly quantities of the recyclable materials removed off site will be recorded in the waste flow table for monthly submission to the SOR.

(ii) Specific measures will be implemented to reduce the generation of waste materials, and thus minimize the amount of waste disposal to landfills. The measures will include:

· sort all excavated materials and recover the inert portion of C&D materials, such as hard rock, soil and broken concrete, for reuse on the Site or, if cannot be used on the Site, disposal to designated outlets for reuse;

· recover all metallic waste for recycling;

· recover all cardboard and paper packaging, and properly stockpile them in dry and covered condition to prevent cross contamination; and

· sort all demolition debris to recover reinforcement bars, mechanical and electrical fittings, hardware and all other fittings/ materials that have established recycling outlets.

(iii) Materials packaging (i.e. paper and cardboard) will be recovered if possible, properly stockpiled in dry and covered environment to prevent cross contamination by other C&D materials. Attention will also be paid to avoid cross contaminate during the course of paper collection for recycling. Arrangements will be made with recycling contractors to ensure that the recyclable materials sorted from the Site are handled with reasonable care. In addition, DBJV has made agreements with certain suppliers for the collection of packaging wastes to further enhance the management of these materials on site.

11.6 Mitigation Measures in EIA

(i) The Section 12.6 of the EIA Report gives recommendations on mitigation measures of waste management. The recommendations were extracted to form an implementation schedule particularly for waste management during construction phase and the schedule is shown in Appendix H.

12.0 Waste monitoring and audit

(i) The aims and objectives of the waste management audit program are:

· To ensure that waste generated by the works is handled, stored, collected, transported and disposed of in accordance with the applicable environmental guidelines and regulations;

· To ensure that the handling, storage, collection and disposal of waste arising from the demolition works complies with the relevant requirements under the Waste Disposal Ordinance and its regulations, and also this WMP;

· To encourage the reuse and recycling of materials.

(ii) For monitoring the Contractor’s waste management system, ET would audit the waste management practices during the weekly environmental site inspection. This evaluates the overall performance of the implementation of the WMP and ensures the appropriate control measures are properly implemented. The results of the waste management audits will be reported in the monthly EM & A reports.

(iii) In the event that any Notice of Non-compliance is received with respect to any waste management issues, the initial corrective action should be proposed to SOR. This shall be in accordance with the requirements of the relevant Event Action Plan for non-compliance and complaints as shown in the following table:

Table 12.1 Event Action Plan for Non-compliance
