E1 EM&A Requirements

E1.1 Introduction

E1.1.1 This Appendix provides a summary of the specific EM&A requirements for Schedule 2 DP2: Road P2 and other roads which are classified as primary/district distributor roads. The same methodology and equipment will be employed for the noise and air quality monitoring as outlined in Sections 2 and 3 of this EM&A Manual.

E2 AIR QUALITY

E2.1 Introduction

E2.1.1 In this section, the monitoring locations for the monitoring and audit of air quality impacts during the construction phase of DP2 and mitigation measures proposed in the EIA report, are presented. As the construction dust is the prime concern, TSP levels shall be monitored to evaluate the dust impact during the construction phase.

E2.2 Monitoring Locations

E2.2.1 Based on the EIA report, two worst affected locations are designated for construction dust monitoring as listed in Table E2.1 and illustrated in Figure 2.2. The status and locations of dust sensitive receivers may change after issuing this manual. If such cases exist, the ET Leader shall propose updated monitoring locations and seek approval from ER and agreement from the IC(E).

Table E2.1 Construction Dust Monitoring Locations

Identification No.	ASR ID in EIA Report	Location
CMA6	A29	Wanchai – Servicemen’s Guides Association
CMA5	A32	Wanchai – Hong Kong Convention & Exhibition Centre

E2.2.2 When alternative monitoring locations are proposed, the proposed site should, as far as practicable:

a) be at the site boundary or such locations close to the major dust emission source;

b) be close to the sensitive receptors; and

c) take into account the prevailing meteorological conditions.

E2.2.3 The ET shall agree with the ER in consultation with the IC(E) on the position of the HVS for the installation of the monitoring equipment. When positioning the samplers, the following points shall be noted:

a) a horizontal platform with appropriate support to secure the samplers against gusty wind should be provided;

b) no two samplers should be placed less than 2 meters apart;

c) the distance between the sampler and an obstacle, such as buildings, must be at least twice the height that the obstacle protrudes above the sampler;

d) a minimum of 2 meters of separation from walls, parapets and penthouses is required for rooftop samplers;

e) a minimum of 2 meters separation from any supporting structure, measured horizontally is required;

f) no furnace or incinerator flue is nearby;

g) airflow around the sampler is unrestricted;

h) the sampler is more than 20 meters from the dripline;

i) any wire fence and gate, to protect the sampler, should not cause any obstruction during monitoring;

j) permission must be obtained to set up the samplers and to obtain access to the monitoring stations; and

k) a secured supply of electricity is needed to operate the samplers.

E2.3 Mitigation Measures

E2.3.1 As described in the EIA Report, the ASRs from Central to Causeway Bay would comply with AQO and EIAO-TM criteria during construction. In order to achieve the air quality criteria, watering with complete coverage of active construction area twice a day and requirements of the Air Pollution Control (Construction Dust) Regulation shall be adhered to during the construction period.

E2.3.2 If the above measures are not sufficient to restore the air quality to acceptable levels upon the advice of ET Leader, the Contractor shall liaise with the ET Leader on some other mitigation measures, propose to ER for approval, and implement the mitigation measures.

E2.3.3 The implementation schedule for the mitigation measures during construction phase and operation phase is presented in Section E9.

E1 NOISE

E1.1 Construction Phase

E1.1.1 Construction noise impacts arising from DP2 are predicted at the identified NSRs. Noise mitigation measures would be required to reduce noise levels to the stipulated standard. A noise monitoring programme shall be undertaken to ensure such mitigation measures would be implemented properly.

E1.1.2 The location of construction noise monitoring station is summarized in Table E3.1 and shown in Figure 3.2.

Table E3.1 Construction Noise Monitoring Stations

Noise Monitoring Station	NSR ID (Based on EIA Report)	Noise Monitoring Location
M1	N2	Causeway Centre

E1.1.3 The status and locations of noise sensitive receivers may change after issuing this manual. If such case exists, the ET Leader shall propose updated monitoring locations and seek approval from EPD and agreement from the ER and the IEC before baseline monitoring commences.

E1.1.4 When alternative monitoring locations are proposed, the monitoring locations shall be chosen based on the following criteria:

(i) at locations close to the major site activities which are likely to have noise impacts;

(ii) close to the noise sensitive receivers; and

(iii) for monitoring locations located in the vicinity of the sensitive receivers, care shall be taken to cause minimal disturbance to the occupants during monitoring.

E1.1.5 The monitoring station shall normally be at a point 1 m from the exterior of the sensitive receiver building facade and be at a position 1.2 m above the ground. If there is problem with access to the normal monitoring position, an alternative position may be chosen, and a correction to the measurements shall be made. For reference, a correction of +3 dB(A) shall be made to the free field measurements. The ET shall agree with the IEC on the monitoring position and the corrections adopted. Once the positions for the monitoring stations are chosen, the baseline monitoring and the impact monitoring shall be carried out at the same positions.

E1.1.6 Construction noise mitigation measures for DP2 are included in Section E9.

E1.2 Operation Phase

E1.2.1 No direct noise mitigation measures are proposed for DP2, road traffic noise monitoring would not be considered necessary.

E2 WATER QUALITY

E2.1 Water Quality Parameters

E2.1.1 In order to ensure that water quality resources are adequately protected during the construction phase of DP2, it will be necessary for the Contractor to undertake audits to ensure the effective implementation of the recommended mitigation measures as outlined in the EIA and Implementation Schedule (Section E9). Section 9 of this EM&A Manual sets out the requirements of the auditing programme.

E3 WASTE MANAGEMENT

E3.1 Waste Control and Mitigation Measures

E3.1.1 Mitigation measures for waste management of the DP2 are summarised below. The Implementation Schedule of the recommended mitigation measures for DP2 is presented in Section E9. In order to ensure that the mitigation measures are properly implemented by the Contractor, regular site inspections by the ET shall be carried out at least once per week. Details of the audit requirements are set out in Section 9 of this EM&A Manual.

Good Site Practices

E3.1.2 Adverse impacts related to waste management are not expected to arise, provided that good site practices are strictly followed. Recommendations for good site practices during the construction activities include:

· Nomination of an approved person, such as a site manager, to be responsible for good site practices, arrangements for collection and effective disposal to an appropriate facility, of all wastes generated at the site.

· Training of site personnel in proper waste management and chemical waste handling procedures.

· Provision of sufficient waste disposal points and regular collection for disposal.

· Appropriate measures to minimise windblown litter and dust during transportation of waste by either covering trucks or by transporting wastes in enclosed containers.

· Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors.

· A recording system for the amount of wastes generated, recycled and disposed of (including the disposal sites).

Waste Reduction Measures

E3.1.3 Good management and control can prevent the generation of a significant amount of waste. Waste reduction is best achieved at the planning and design stage, as well as by ensuring the implementation of good site practices. Recommendations to achieve waste reduction include:

· Sort C&D waste from demolition of the existing waterfront structures to recover recyclable portions such as metals.

· Segregation and storage of different types of waste in different containers, skips or stockpiles to enhance reuse or recycling of materials and their proper disposal.

· Encourage collection of aluminium cans, PET bottles and paper by providing separate labelled bins to enable these wastes to be segregated from other general refuse generated by the work force.

· Any unused chemicals or those with remaining functional capacity shall be recycled.

· Use of reusable non-timber formwork, such as in casting the tunnel box sections, to reduce the amount of C&D material.

· Proper storage and site practices to minimise the potential for damage or contamination of construction materials.

· Plan and stock construction materials carefully to minimise amount of waste generated and avoid unnecessary generation of waste.

E3.1.4 In addition to the above measures, specific mitigation measures are recommended below for the identified waste arisings to minimise environmental impacts during handling, transportation and disposal of these wastes.

General Refuse

E3.1.5 General refuse should be stored in enclosed bins or compaction units separate from C&D material. A licensed 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.

Chemical Wastes

E3.1.6 After use, chemical wastes (for example, cleaning fluids, solvents, lubrication oil and fuel) should be handled according to the Code of Practice on the Packaging, Labelling and Storage of Chemical Wastes. Spent chemicals should be collected by a licensed collector for disposal at the CWTF or other licensed facility, in accordance with the Waste Disposal (Chemical Waste) (General) Regulation.

Construction and Demolition Material

E3.1.7 The C&D material should be sorted on-site into inert C&D material (that is, public fill) and C&D waste. Considering that a large quantity of C&D material will be generated from the demolition works and in order to minimise the impact resulting from collection and transportation of material for off-site disposal, it is recommended that the inert C&D material should be re-used on-site in the reclamation works as far as practicable. All the suitable (inert) material should be broken down to 250 mm in size for reuse as public fill and surcharge in the WDII reclamation. C&D waste, such as wood, glass, plastic, steel and other metals should be reused or recycled and, as a last resort, disposed of to landfill. It is recommended that a suitable area be designated to facilitate the sorting process and a temporary stockpiling area will be required for the separated materials.

E3.1.8 In order to monitor the disposal of public fill and C&D waste at public fill reception facilities and landfills, respectively, and to control fly tipping, a trip-ticket system should be included as one of the contractual requirements and implemented by an Environmental Team undertaking the Environmental Monitoring and Audit work. An Independent Environmental Checker should be responsible for auditing the results of the system.

E4 LAND CONTAMINATION

E4.1.1 As no land contamination impacts were identified for both construction and operational phase of the Project, EM&A works for land contamination were therefore considered not necessary.

E5 MARINE ECOLOGY

E5.1.1 As no adverse ecological impact on marine resources is identified, no necessary mitigation measures and monitoring programme specific for the marine ecology is considered as required in the impact assessment. The mitigation measures and monitoring programme recommended in the water quality impact assessment to control water quality would also serve to protect marine ecological resources from indirect impacts and ensure no adverse impact on marine life would be resulted from this designated project.

E6 LANDSCAPE AND VISUAL

E6.1 Introduction

E6.1.1 The EIA has recommended landscape and visual mitigation measures to be undertaken during both the construction and operational phases of the project. This section outlines the monitoring and audit of these measures.

E6.1.2 The key landscape resources, landscape character areas and visual sensitive receivers are shown in Figures 8.1a, 8.1b, 8.2a, 8.2b, 8.3a, 8.3b, 8.3c.

E6.2 Monitoring Details

E6.2.1 The design, implementation and maintenance of landscape mitigation measures should be checked to ensure that they are fully realised and that potential conflicts between the proposed landscape measures and any other project works and operational requirements are resolved at the earliest possible date and without compromise to the intention of the mitigation measures.

Table E8.1 Monitoring Programme

Design

E6.2.2 The mitigation measures proposed within the EIA to mitigate the landscape and visual impacts of the scheme should be embodied into the detailed engineering design and landscape design drawings and contract documents. Designs should be checked to ensure that the measures are fully incorporated and that potential conflicts with civil engineering, geo-technical, structural, lighting, signage, drainage, underground utility and operational requirements are resolved prior to construction.

E6.2.3 The Client should prepare a detailed 5-Year Management Programme for the long-term management and maintenance of the planting works following the Establishment periods. The Programme should include evaluation and objectives for management, details of the operations to be undertaken to achieve these objectives, and outline of work programmes.

Construction & Establishment Period

E6.2.4 The implementation of landscape construction works and subsequent maintenance operations during the 12-month establishment period must be supervised by fully qualified Landscape Resident Site Staff (Registered Landscape Architect or Professional Member of the Hong Kong Institute of landscape Architects).

E6.2.5 Measures to mitigate landscape and visual impacts during construction should be checked to ensure compliance with the intended aims of the measures.

E6.2.6 The progress of the engineering works shall be regularly reviewed on site to identify the earliest practical opportunities for the landscape works to be undertaken.

Long Term Management

E6.2.7 The success or otherwise of all planting works intended to mitigate the visual and landscape impact of the roads, the noise barriers/screening/semi-enclosures and street lighting shall be monitored during the first ten years of the operational phase of the project. Any areas of vegetation which have failed to establish, should be corrected by the appropriate maintenance authorities at the earliest opportunity. Monitoring should include the long-term maintenance of the planting works under the detailed 5-Year Management Programme.

E6.3 Baseline Monitoring

E6.3.1 A photographic record of the site at the time of the contractor’s possession of the site shall be prepared by the Contractor and approved by the ER. The approved photographic Record shall be submitted to the Project proponent, ET, IC(E) and EPD for record.

E6.4 Event/Action Plan for Landscape and Visual Works

Construction Phase
S5.8	Construction Runoff and Drainage Exposed soil areas should be minimised to reduce the potential for increased siltation, contamination of runoff, and erosion. Construction runoff related impacts associated with the above ground construction activities can be readily controlled through the use of sediment traps and adequate maintenance of drainage systems to prevent flooding and overflow. Construction site should be provided with adequately designed perimeter channel and pre-treatment facilities and proper maintenance. The boundaries of critical areas of earthworks should be marked and surrounded by dykes or embankments for flood protection. Temporary ditches should be provided to facilitate runoff discharge into the appropriate watercourses, via a silt retention pond. Permanent drainage channels should incorporate sediment basins or traps and baffles to enhance deposition rates. The design of efficient silt removal facilities should be based on the guidelines in Appendix A1 of ProPECC PN 1/94. Ideally, construction works should be programmed to minimise surface excavation works during the rainy season (April to September). All exposed earth areas should be completed as soon as possible after earthworks have been completed, or alternatively, within 14 days of the cessation of earthworks where practicable. If excavation of soil cannot be avoided during the rainy season, or at any time of year when rainstorms are likely, exposed slope surfaces should be covered by tarpaulin or other means. A sediment tank constructed from pre-formed individual cells of approximately 6 ‑ 8 m3 capacity can be used for settling ground water prior to disposal; Open stockpiles of construction materials (for examples, aggregates, sand and fill material) of more than 50 m3 should be covered with tarpaulin or similar fabric during rainstorms. Measures should be taken to prevent the washing away of construction materials, soil, silt or debris into any drainage system.	Work site / During the construction period	Contractor		Ö			ProPECC PN 1/94; WPCO (TM-DSS)
S5.8	Manholes (including newly constructed ones) should always be adequately covered and temporarily sealed so as to prevent silt, construction materials or debris being washed into the drainage system and storm runoff being directed into foul sewers. Precautions to be taken at any time of year when rainstorms are likely, actions to be taken when a rainstorm is imminent or forecast, and actions to be taken during or after rainstorms are summarised in Appendix A2 of ProPECC PN 1/94. Particular attention should be paid to the control of silty surface runoff during storm events. Oil interceptors should be provided in the drainage system and regularly cleaned to prevent the release of oils and grease into the storm water drainage system after accidental spillages. The interceptor should have a bypass to prevent flushing during periods of heavy rain. All vehicles and plant should be cleaned before leaving a construction site to ensure no earth, mud, debris and the like is deposited by them on roads. An adequately designed and located wheel washing bay should be provided at every site exit, and wash-water should have sand and silt settled out and removed at least on a weekly basis to ensure the continued efficiency of the process. The section of access road leading to, and exiting from, the wheel-wash bay to the public road should be paved with sufficient backfall toward the wheel-wash bay to prevent vehicle tracking of soil and silty water to public roads and drains.	Work site / During the construction period	Contractor		Ö			ProPECC PN 1/94; WPCO (TM-DSS)
S5.8	It is recommended that on-site drainage system should be installed prior to the commencement of other construction activities. Sediment traps should be installed in order to minimise the sediment loading of the effluent prior to discharge into foul sewers. There shall be no direct discharge of effluent from the site into the sea. All temporary and permanent drainage pipes and culverts provided to facilitate runoff discharge shall be adequately designed for the controlled release of storm flows. All sediment control measures shall be regularly inspected and maintained to ensure proper and efficient operation at all times and particularly following rain storms. The temporarily diverted drainage shall be reinstated to its original condition when the construction work is finished or the temporary diversion is no longer required.

	All fuel tanks and store areas shall be provided with locks and be sited on sealed areas, within bunds of a capacity equal to 110% of the storage capacity.
S5.8	Sewage from Construction Work Force Construction work force sewage discharges on site shall be connected to the existing trunk sewer or sewage treatment facilities. The construction sewage shall be handled by portable chemical toilets prior to the commission of the on-site sewer system. Appropriate numbers of portable toilets shall be provided by a licensed contractor to serve the large number of construction workers over the construction site. The Contractor shall also be responsible for waste disposal and maintenance practices.	Work site / During the construction period	Contractor		Ö			ProPECC PN 1/94; WPCO (TM-DSS)
