To support the increased use of natural gas in Hong Kong from 2020 onwards, Castle Peak Power Company Limited (CAPCO) and The Hongkong Electric Co., Ltd. (HK Electric) have identified that the development of an offshore liquefied natural gas (LNG) receiving terminal in Hong Kong using Floating Storage and Regasification Unit (FSRU) technology (‘the Hong Kong Offshore LNG Terminal Project’) presents a viable additional gas supply option that will provide energy security through access to competitive gas supplies from world markets. The Hong Kong Offshore LNG Terminal Project will involve the construction and operation of an offshore LNG import facility to be located in the southern waters of Hong Kong, a double berth jetty, and subsea pipelines that connect to the gas receiving stations (GRS) at the Black Point Power Station (BPPS) and the Lamma Power Station (LPS).

The Environmental Impact Assessment (EIA) Report for the Hong Kong Offshore LNG Terminal Project was submitted to the Environmental Protection Department (EPD) of the Hong Kong Special Administrative Region Government in May 2018. The EIA Report (EIAO Register No. AEIAR-218/2018) was approved by EPD and the associated Environmental Permit (EP) (EP-558/2018) was issued in October 2018. An application for Further Environmental Permits (FEP) was made on 24 December 2019 to demarcate the works between the different parties. The following FEPs were issued on 17 January 2020 and the EP under EP-558/2018 was surrendered on 5 March 2020:

§ the double berth jetty at LNG Terminal under the Hong Kong LNG Terminal Limited, joint venture between CAPCO and HK Electric (FEP-01/558/2018) ([1]);

§ the subsea gas pipeline for the BPPS and the associated GRS in the BPPS under CAPCO (FEP-03/558/2018) ([2]); and

§ the subsea gas pipeline for the LPS and the associated GRS in the LPS under HK Electric (FEP-02/558/2018) ([3]).

The location plan for the works associated with the double berth jetty at LNG Terminal (‘the Project’) is provided in Figure 1.1.

1.2 Objectives of the Waste Management Plan

This Waste Management Plan (WMP) for the Project has been prepared in accordance with Condition 2.11 of the Further Environmental Permit FEP-01/558/2018/A.

FEP No. FEP-01/558/2018/A, Condition 2.11:

“The Permit Holder shall, no later than 1 month before the commencement of construction of the Project, deposit with the Director 3 hard copies and 1 electronic copy of a waste management plan (WMP) for the construction of the Project. The WMP shall describe the arrangements for avoidance, reuse, recovery and recycling, storage, collection, treatment and disposal of different categories of waste to be generated from the construction activities and shall include the recommended mitigation measures on waste management in the approved EIA Report (Register No. AEIAR-218/2018). The WMP shall describe the disposal arrangements and locations of the dredged marine sediments and construction and demolition materials arising from the construction of the Project. Marine dumping permit system and trip ticket system shall be described in the WMP. The deposited WMP shall be fully and properly implemented during construction of the Project.”

The key objectives of this WMP are to:

§ describe the arrangements for avoidance, reuse, recovery and recycling, storage, collection, treatment and disposal of different categories of waste to be generated from the construction activities;

§ include the recommended mitigation measures on waste management in the approved EIA Report;

§ describe the disposal arrangements and locations of the dredged marine sediments ([4]) and construction and demolition materials arising from the construction of the Project; and

§ describe marine dumping permit system ([5]) and trip ticket system.

The WMP will be reviewed and updated as appropriate, throughout the course of the construction works to confirm that it remains current with the latest detailed information and works practice.

1.3 Waste Management Regulations and Guidelines

1.3.1 General

Various types of wastes would be generated during the course of the Project and each waste type requires different approach for management and disposal as stipulated in the waste legislation and guidelines. The relevant statutory and non-statutory requirements regarding waste management are summarised in the sections below.

1.3.2 Statutory Requirements

The following legislation relates to the handling, treatment and disposal of wastes in Hong Kong, and would be observed with regard to all wastes generated and requiring disposal, where applicable:

§ Waste Disposal Ordinance (Cap 354)

§ Waste Disposal (Chemical Waste) (General) Regulation (Cap 354C)

§ Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap 354N)

§ Buildings Ordinance (Cap 123)

§ Land (Miscellaneous Provisions) Ordinance (Cap 28)

§ Public Health and Municipal Services Ordinance (Cap 132) - Public Cleansing and Prevention of Nuisances (Urban Council) and (Regional Council) By-Laws

§ Merchant Shipping (Prevention and Control of Pollution) Ordinance (Cap 413)

§ Summary Offences Ordinance (Cap 228)

1.3.2.1 Waste Disposal Ordinance (Cap 354)

The Waste Disposal Ordinance (WDO) prohibits the unauthorised disposal of waste. Construction waste is not directly defined in the WDO, but is considered to fall within the category of “trade waste”. Under the WDO, wastes can only be disposed of at sites licensed by EPD.

1.3.2.2 Waste Disposal (Chemical Waste) (General) Regulation (Cap 354C)

Under the Waste Disposal (Chemical Waste) (General) Regulation all producers of chemical wastes (including asbestos) must register with EPD and treat their wastes either utilising on-site plant licensed by EPD, or arranging for a licensed collector to take the wastes to a licensed facility. The regulation also prescribes the storage facilities to be provided on site, including labelling and warning signs, and requires the preparation of written procedures and training to deal with emergencies such as spillages, leakages, or accidents arising from the storage of chemical wastes.

1.3.2.3 Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap 354N)

The current policy related to the dumping of construction and demolition (C&D) materials is documented in the Development Bureau (Works) Technical Circular No. 09/2011, ‘Enhanced Control Measures for Management of Public Fill’. Construction and demolition materials that are wholly inert, namely public fill, should not be disposed of to landfill, but taken to public filling areas, which usually form part of reclamation schemes.

Under the WDO and the Charging Regulation, wastes can only be disposed of at designated waste disposal facilities licensed by EPD. For construction work with a value of more than HK$1M, the main contractor is required to establish a billing account at EPD before transporting the construction waste to the designated waste disposal facilities (e.g. landfill, public fill etc.). The vessels for delivering construction waste to public fill reception facility would need prior approval from EPD. Breach of these regulations can lead to a fine and/or imprisonment.

1.3.2.4 Buildings Ordinance (Cap 123)

Regulation of private projects, as opposed to government public works projects, is subject to the Buildings Ordinance (BO) and relevant Practice Notes for Authorised Persons, Registered Structural Engineers and Registered Geotechnical Engineers (PNAPs). Measures have been introduced under PNAP ADV-19 Construction and Demolition Waste, to enhance the management of C&D materials, and to minimise its generation at source. The enhancement measures include:

§ Identifying opportunities to prevent waste during both the project planning and design stage as well as construction stage; and

§ Requiring the Contractor to prepare a WMP including areas described in PNAP ADV-19 and submit to the Project Proponent for agreement.

1.3.2.5 Land (Miscellaneous Provisions) Ordinance (Cap 28)

The Land (Miscellaneous Provisions) Ordinance requires that dumping licences be obtained by individuals or companies who deliver public fill to public filling areas. The Civil Engineering & Development Department (CEDD) issues the licences under delegated powers from the Director of Lands.

1.3.2.6 Public Health and Municipal Services Ordinance (Cap 132) - Public Cleansing and Prevention of Nuisances (Urban Council) and (Regional Council) By-Laws

The Public Cleansing and Prevention of Nuisances By-Laws provide further controls on the illegal tipping of wastes on unauthorized (unlicensed) sites.

1.3.2.7 Merchant Shipping (Prevention and Control of Pollution) Ordinance (Cap 413)

The Merchant Shipping (Prevention and Control of Pollution) Ordinance and its subsidiary regulations prohibit the discharge of wastewater and garbage from vessels.

Hong Kong has implemented the International Convention for the Prevention of Pollution from Ships 1973 as amended by the 1978 Protocol (universally known as MARPOL) and the MARPOL related requirements are mainly implemented under the Merchant Shipping (Prevention and Control of Pollution) Ordinance. Under the requirements, liquid oil waste or any other mixtures which contain oil and noxious liquid substances or any such residues shall not be discharged into the sea. In Hong Kong, the Chemical Waste Treatment Centre (CWTC) is the reception facility for oily waste discharged from vessels.

1.3.2.8 Summary Offences Ordinance (Cap 228)

It contains provisions related to littering offences including marine littering.

3. Category of Waste Materials and Measures on Waste Management

3.1 Expected Sources of Waste Generation

During the construction phase of the Project, the main activities include the construction of the double berth jetty. These activities will potentially result in the generation of wastes. The typical waste types associated with these activities include:

§ C&D materials from the construction of jetty, including the assembly of prefabricated equipment and structural formation works;

§ Chemical waste, such as used cleansing chemicals, lubricants, fuel waste, spent reagent etc, from maintenance of construction plant and equipment for both land and marine-based works; and

§ General refuse from land and marine-based construction workforce, such as food scraps, aluminium cans, PET bottles and waste paper, and floating refuse.

Mitigation measures, where appropriate, have been recommended as part of the EIA to avoid or reduce potential adverse environmental impacts associated with handling, collection, transport and disposal of waste arising from the construction of the proposed Project. The details are summarised in Annex A.

3.2 Waste Management Hierarchy

The various waste management options are categorised in terms of preference from an environmental viewpoint. The options considered to be most preferable have the least environmental impacts and are more sustainable in the long term. The hierarchy is as follows:

§ Avoidance and reduction - avoid and minimize waste through careful planning and design works;

§ Re-use of materials - reuse construction waste such as excavated material, used wooden plants and ferric materials;

§ Recovery and recycling - undertake on-site or off-site waste recycling; and

§ Storage, collection, treatment and disposal - properly store, collect, treat and dispose of waste in accordance with legislative requirements, guidelines and good practices.

In the context of waste reduction, environmentally responsible purchasing would involve the introduction of practices that discourage unnecessary purchases and encourage the purchase of products with reduced packaging, increased durability and materials with high recycled content, such as, recycled paper, steel and other raw construction materials.

Waste minimisation is best achieved through careful planning, design and supervision. Good management practices would reduce and prevent large amount of waste generated. Raw materials would be managed from the first instance before they are ordered and delivered to the site. Good estimation and planning would minimize the amount of raw materials wasted. The generation of waste would be controlled at source.

3.3 Waste Management Options

Waste management options will be exercised by the Contractor according to the hierarchy described below:

§ Pre-identification between reusable and recyclable materials by producing a list of works activities that will generate C&D materials;

§ Avoidance and reduction - to minimise waste generation through careful planning and design works; good site management to minimise over ordering and avoid wastage;

§ Contamination with collected reusable materials;

§ Reuse of materials - to reuse inert C&D material, timber material and metal on-site;

§ Recovery and recycling - to undertake on-site or off-site waste recycling by encourage collection of aluminium cans, PET bottles and paper generated by the workforce of the Contract; separate labelled bins will be provided and located on site wherever possible; and

§ Treatment and disposal - to properly treat or dispose of waste materials in accordance with legislative requirements, guidelines and good practices.

3.4 Measures of Good Site Management

Recommendations for good site practices to facilitate the waste management hierarchy as described in the section above during the construction phase and all other office related works include, but not limited to:

§ Nomination of an approved person, such as a superintendent, 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 handling procedures;

§ Regular collection of on-site waste will be implemented, with provision of sufficient waste disposal points and containers to avoid overflow of waste materials;

§ Regular cleaning and maintenance programme for drainage systems, sumps and oil interceptors. Excess materials will be cleaned from the decks and exposed fittings of the marine vessels;

§ Optimising the use of metal materials required in the work process and maximising the reuse of inert C&D materials within the construction site.

§ Ensure any chemicals utilised on the marine vessels are not deposited into surrounding water;

§ All water and other liquid waste products arising on site will be collected, removed from site via a suitable and properly designed temporary drainage system and disposed of at a location and in a manner that will not cause either pollution or nuisance;

§ Provide adequate precautions to ensure that no materials of any kind is allowed to be pushed, washed down, fall or deposited onto nearby marine waters; and

§ Prohibit any burning of debris and other construction waste within construction areas.

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

§ Sorting on site to recover the inert portion of C&D materials;

§ Sorting of plastic waste and deliver to recycling company;

§ 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;

§ Use of the materials (such as formworks and hoardings) in the construction would be calculated before purchasing in order to minimize waste generation; and

§ Use of metal formworks and hoardings, and they would be recycled after demolition on site as far as it can before disposal.

3.5 Waste Reduction Measures

To prevent over-generation of construction waste, the Contractor will implement the following waste reduction measures step by step according to their specific waste type:

3.5.1 C&D Materials

§ Regular review with HKLTL during the construction phase to assess the amount of waste that is likely to be generated;

§ Each delivery of construction materials will be identified and kept separately to avoid over ordering;

§ 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; and

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

3.5.2 Chemical Waste

§ Order and deliver appropriate quantity of chemicals to avoid unnecessary storage of excess chemicals;

§ Avoiding unplanned wastage of chemicals by cautiously utilising the chemicals in accordance with the manufacturer’s instructions;

§ Determine the chemicals’ expiry date to maximise its usage; and

§ Any unused chemicals, and those with remaining functional capacity, shall be recycled as far as possible.

3.5.3 General Refuse

§ Reduce generation of printing paper through electronic documentation;

§ Encourage collection of aluminium cans by providing separate labelled bins to enable this waste to be segregated from other general refuse generated by the work force; and

§ Burning of refuse within site boundary is prohibited by law and will not be undertaken.

3.6 Reuse and Recycling

All C&D materials arising from or in connection with the construction of the Project will be sorted on the site to recover reusable and/or recyclable materials. The Contractor will implement appropriate action to these materials according to their categories.

3.6.1 Inert C&D materials

Reuse and recycling could divert any C&D material from waste stream back to the construction cycle. The Waste Flow Table as shown in Annex B will be maintained and updated regularly to keep track of the recycling progress.

3.6.2 Non-Inert C&D material

Ensure consumable accessories and equipment in the office, namely toner cartridge, fluorescent tube and batteries, will be stored and recycled after their contents were exhausted. Office paper will also be reused as much as possible before considering recycling. Aluminium cans and PET bottles will be collected and recycled using separate labelled bins.

3.7 Material Control and Maintenance

Mis-ordering construction materials, together with poor storage and maintenance of raw materials could result in their deterioration and damages. To avoid accumulation, the right amount of raw materials will be ordered at the right time with proper control and documentation on material flow. Any surplus materials will be returned to stock in centralised area with suitable protective measures.

3.8 Waste Target Summary

The targets set for the Contractor during construction phase will cover, but not limited to, the followings:

§ Producing a list of work processes or activities that will generate C&D materials for general waste management;

§ All surplus wastes are to be sorted to recover any inert portion of C&D materials;

§ All metallic waste to be recovered for collection by recycling contractors;

§ Glass and plastic bottles will be recovered for collection where practicable;

§ All cardboard and paper packaging will be recovered on site, properly stockpiled in dry condition and covered to prevent cross-contamination by other C&D materials and will be collected by recycling contractors;

§ All chemical wastes to be collected and properly disposed of by specialist contractors; and

§ All inert materials will be sorted to recover for reuse on site or disposal to designated outlets.

3.9 Waste Management Records

The Contractor is responsible for keeping waste management records on site. These records include, but not limited to, the following:

§ Relevant licences and permits, including dumping licences and registration as chemical waste producer;

§ Records of quantities of waste generated, recycled and disposed of (including the selected disposal sites);

§ Records for trip tickets and documentation for collection and tipping of waste and waste removal;

§ Disposal recording system of vehicular trip of transporting C&D materials and its mechanism for collection of returned form together with recipe from public filling areas or landfill site;

§ Method for estimation of load for inert C&D materials, metals, papers / cardboard or other C&D wastes;

§ The receipt for recycling of inert C&D material, paper / cardboard and metal; and

§ Keeping the attendance record of each waste management training session.

The Construction and Demolition Material Disposal Delivery Form (DDF) will be used for each and every vehicular trip transporting C&D materials off site. Prior to the vehicle leaving the site, HKLTL’s Representative will insert the date, time of departure, vehicle licence plate number, designated public filling facility / landfill, and other information as required, and stamp the form. HKLTL’s Representative will then retain the first strip of the form and pass the rest to Contractor’s Representative. The form will be carried on board the vehicle at all times throughout the vehicular trip.

A comprehensive register of the DDF issued will be maintained and available for inspection by HKLTL’s Representative upon request. The following records will be kept for monitoring of the DDF issued. Daily Record Summary (DRS) and the Waste Flow Table (WFT) (see Annex B for the proforma) should be completed and submitted to HKLTL’s Representative for record.

3.9.1 Waste Flow Table (WFT)

Record of the quantities of C&D materials generated each month will be maintained using the monthly summary WFT. The Contractor will complete and submit the monthly summary of WFT to HKLTL by not later than the 7^th day of each month following the reporting month, or if it is a General Holiday, the day following the General Holiday, or a later date as agreed by HKLTL. The WFT shall also be made available to ET and IEC.

Specific trip ticket and records for internal transfer of C&D materials and imported fill materials will also be kept for monitoring whatever necessary.

For recyclable materials, Contractor’s Representative will record the quantities of all the recyclable materials before removal off the construction site by the recycling contractors, and include the details in the WFT for submission to HKLTL’s Representative.

In order to ensure proper disposal of C&D materials, enhancement measures to further improve the Trip Ticket System recording system, a video recording system shall be installed and disposal shall be checked against survey record. Such video recording system used to monitor the vehicular exit / entrance of the site and pier area of the site.

3.10 Training for Waste Management

The Contractor will provide training on waste management in the site-specific environmental training and its refresher training for all Contractor staff and the sub-contractors. The training will cover the waste management procedures and targets as described in this WMP.

Toolbox talks for the topic on on-site sorting of C&D materials will be organized by the Contractor to promote awareness on handling, sorting, reuse and recycling of C&D to all levels of staff along with subcontractors.

3.11 Waste Monitoring and Audit

The Contractor will be responsible for all waste management activities during the construction phase of the Project. The Contractor must ensure that all wastes produced during the construction phase are handled, stored and disposed of in accordance with EPD’s regulations and requirements and in line with good waste management practices.

The Contractor should perform regular site inspection (at least once per week) to determine if wastes are being managed in accordance with approved procedures. Waste materials generated during the construction works, such as inert C&D material, general refuse and chemical wastes, are recommended to be monitored on a weekly basis to ensure that proper storage, transportation, reuse, recycling and disposal practices are being implemented. This monitoring of waste management practices will ensure that these solid and liquid wastes are not disposed into the nearby waters. The Contractor should be responsible for the implementation of all mitigation measures to minimise waste or address problems arising from the waste materials.

In addition, the ET will carry out weekly site inspections in accordance with the Updated EM&A Manual of the Project with reference to the checklist detailed in Table 3.1 below. The ET will identify any non-compliance with the Updated EM&A Manual and the WMP, and will report them accordingly. The results of the waste management audits would be reported in the monthly EM&A reports.

4. Disposal Arrangement, Location and Procedures

4.1 Estimated Quantities of C&D Materials & Other Wastes

The following types of waste would be generated from the construction works and they are summarised in Table 4.1:

§ Inert and non-inert C&D materials;

§ Chemical waste; and

§ General refuse, including recyclable wastes (paper, plastic and metal).

Table 4.1 Summary of Estimated Waste Arising and Recommended Waste Management Arrangements

Types of Waste	Approximate Quantity	Disposal Locations
C&D materials	§ Total: 5,000m³ § Inert: 4,500m³ § Non-inert: 500m³	§ Inert C&D materials: Public fill reception facilities directly or Outlying Island Transfer Facilities § Non-inert C&D materials: WENT Landfill directly or via Outlying Island Transfer Facilities
Chemical waste	§ Few hundred litres per month	§ CWTC or other licensed chemical waste treatment facilities
General refuse, including floating refuse	§ ~40kg per day	§ Recyclable materials: on-site sorting and off-site recycling § Non-recyclable refuse: WENT Landfill directly or via Outlying Island Transfer Facilities

The quantities of disposed C&D materials will be recorded under the barcode trip ticket system by using the “C&D Material Disposal Delivery Form”. In addition, the filled “CHIT” / Vessel “CHIT” will also be presented to the landfill / public fill site as part of the system for the disposal charging scheme which had already been officially effective in January 2006. Waste transaction records could be obtained either in the waste disposal facilities right after the transaction or retrieved from the EPD bill statement each month.

4.2 Acceptance Criteria for the Government Disposal Facilities

Inert C&D materials shall dispose to Fill Banks (e.g. Tuen Mun Area 38, TKO Area 137 etc). Mixing of non-inert C&D materials with inert C&D materials will result in rejection for disposal of C&D materials at Fill Banks.

For non-inert C&D materials, the designated disposal facility is depended on the waste depth / weight ratio of the vehicle to transport the non-inert C&D materials off site. The summary of waste acceptance criteria for landfill and sorting facilities for non-inert C&D materials is provided in Table 4.2 below.

Table 4.2 Waste Acceptance Criteria for Landfill and Sorting Facilities for Non-inert C&D Materials

Vehicle Type	Waste Depth	Weight Ratio (Note 1)	Designated Facility

	1.5m or below	0.20 or below	Landfill
	1.5m or below	Over 0.20	Sorting Facility
Demountable Vehicle	Over 1m	No restriction	Landfill
	1m or below	0.25 or below	Landfill
	1m or below	Over 0.25	Sorting Facility

Note 1: Weight ratio = The net weight of C&D materials / Permitted Gross Vehicle Weight

The Contractor will comply with the acceptance criteria laid down by the operators of the corresponding fill bank(s) and landfill(s), as outlined below:

4.3 Procedures of the Trip Ticket System

A reputable waste collector will be identified first and employed to remove and transport the stored waste from the site area. Before the commencement of the construction phase, the Contractor will open a billing account for the Hong Kong Offshore LNG Terminal Project with EPD in accordance with the Waste Disposal (Charges for Disposal of Construction Waste) Regulation for the payment of disposal charges to facilitate C&D waste transaction recording and billing to prevent any illegal waste dumping. Disposal destinations will first be approved by HKLTL before proceeding. The flow charts of the Trip Ticket System for disposal of C&D materials by barges and dump trucks are provided in Annex C. The general steps of the C&D waste transportation are provided below:

§ For each load of C&D materials leaving the construction site, the Contractor’s transportation personnel must bear a duly completed and signed CHIT form. Their respective usage are described as follows.

o The CHIT should be used for off-site delivery of C&D material to prescribed facility as defined under Waste Disposal (Charges for Disposal of Construction Waste) Regulation (Cap. 354N), such as the West New Territories Landfill (WENT).

§ The Contractor will also sign Part 1 of the Daily Record Summary (DRS) before departure of the trucks / barges.

§ C&D waste will be transferred from the construction barge to landside by derrick lighter, transporting vessels or waste collection barges. Then, dump truck or grab trucks will be used to transfer the C&D waste to landfill or other waste disposal facilities.

§ The truck driver or barge operator will proceed to the disposal facilities as specified in the CHIT or DDF. The CHIT / DDF will be presented by the truck driver / barge operator at the facility entrance gate before proceeded with the disposal operation.

§ Disposal of the C&D materials will be permitted if the materials accords the criteria in Cap. 354N. The disposal facility operator will provide the truck driver / barge operator a transaction record slip and a stamped CHIT / DDF for record.

§ For disposal at a prescribed facility, the Contractor will check the information recorded in the DRS and check the site record against data from EPD’s website [http://www.epd.gov.hk/epd/misc/cdm/scheme.htm#j].

§ The Contractor will submit the completed Part 1 and Part 2 of the DRS form to HKLTL within 1 working day for prescribed facility and within 3 working days for other disposal ground after the records have been finalized.

The Contractor will maintain a daily record of C&D materials disposal from the site including CHIT / DDF numbers, vehicle registration marks, driver’s particulars, approximate volume, C&D materials type, designated disposal ground, departure time from the site, actual disposal ground and arrival time at disposal ground.

In the case that an irregularity is observed from the disposal records provided by the Contractor, supporting evidence such as the duly stamped CHIT / DDF will be submitted to HKLTL to confirm the procedure of the delivery trips in question.

All the waste transportations truck will be checked by the Contractor for valid Dumping Licences and were fitted with a mechanical cover before leaving the site area.

4.4 Measures to be Implemented during Transportation of Wastes

The following measures will be implemented during transportation of wastes to avoid leakage on public areas:
