1 . I N T R O D U C T I O N

1.1 Purpose

The purpose of this document is to provide guidance and instructions to all Brunei Shell Petroleum (BSP) staff and contractors on the responsible management of wastes generated from our activities.

A primary objective of this procedure is the protection of human health and the environment against the potentially harmful effects of waste materials.

More specifically the procedure provides:

• a systematic approach to ensure that the properties of all the various wastes involved are adequately considered in deciding the best method and destination for final disposal;

• a mechanism for recording the quantities of waste disposed, and its source;

• essential information for effective management of waste contractors and operation of disposal sites; and

• protection against possible future liabilities.

Therefore, when properly applied it will ensure an acceptable level of waste management performance and ensures the Company's 'Duty of Care' responsibilities.

1.2 Scope

This procedure will be applied to all BSP business activities and to those activities undertaken by third parties where BSP has prevailing influence. Other Brunei Shell Companies (BLNG, Refinery, BSM and BST) may make use of this procedure and the waste disposal arrangements defined.

This procedure does not include continuous aqueous effluents and gaseous emissions or the disposal of explosives or sealed source radioactive wastes (ie in equipment used for inspection, testing, survey and x-ray). The latter are addressed in:

BSP-02-Procedure-1655 : Explosives (Module 21)

BSP-02-Guideline-1631 : Ionising Radiation Safety (Module 20).

Asset holders, activity executors and line supervisors are responsible for ensuring that all waste disposal activities carried out in their area(s) of responsibility are compliant with this procedure. Contract Holders are responsible for ensuring compliance by contractors. Contractors are to ensure compliance of their subcontractors.

Deviations from the procedure are permitted only when they have been approved in writing by the Environmental Affairs department (HSE/5) before the deviation is scheduled to occur. Such a request shall be submitted by at least a department head. Deviations will only be approved in exceptional circumstances.

This document is primarily intended for use by asset holders, process owners, activity executors, line supervisors and contractor management whose scope of work includes waste disposal. All employees involved in waste disposal need to be aware of the contents and understand those parts which are applicable to their work.

This document also supports BSP's progamme of ISO 14001 certification. Asset / Service Units should be able to demonstrate through Aspect Registers and HSE Cases, the local arrangements for managing wastes.

1.3 Background

Waste is defined as:

"those substances or objects which no longer have a commercial value and as such cannot be economically re-used, repaired or recycled".




The generation of waste represents an inefficient use of resources and energy. The term “waste handling” encompasses the storage, collection, transportation, recovery and final disposal of wastes. Compliance with, and implementation of these procedures, and the development and implementation of work instructions for waste management, by all employees with waste management responsibilities is fundamental to achieving improved standards. Good housekeeping is an essential part of waste management.

The activities of an oil and gas business generate a substantial quantity of waste which must be correctly disposed of if environmental pollution and threats to human health are to be avoided. This can present major HSE hazards and it is the responsibility of persons involved in the waste cycle to ensure that the correct procedures are adhered to at all times.

BSP undertakes it's business activities in accordance with the Agreements with the Government of Brunei Darussalam, the Laws of Brunei Darussalam and it's Corporate Policies and Management Systems.

Although legislation concerning HSE issues in Brunei Darussalam is at present limited and there is no legislation specifically written for the protection of the environment (1), the Petroleum Mining Act (1963) and the Company’s Onshore Concession Agreements contain provisions which have implications for the disposal of waste. The agreements include various requirements for the Company to prevent soil and groundwater pollution, to properly dispose of wastes and to comply at all times with good environmental practice.

Further details on legal requirements are contained in :

BSP-02- Standard- 1635 : Environmental Legislation & Quality Standards (Module 50).

BSP is implementing a programme to obtain ISO 14001 certificate. ISO14001 is an international environmental management system standards, against which companies can be certified to demonstrate responsible environmental management. An integral part of BSP's ISO14001 certification is ensuring compliance with this waste management procedure.

Local arrangements for segregation and management of wastes are summarised in the AU/SU Environmental Aspect Registers, forming part of HSE Cases and ISO14001 requirements.

2.1 Waste Management Strategy

The overall aim is to reduce the volume of residual waste which requires disposal at each stage of the waste cycle. This is expressed as:

• Reduction : generate less waste through more efficient practices;

• Reuse : re-use waste materials in their original form;

• Recycle : convert waste back into a reusable material;

• Recover : extract material or energy from waste for other uses; and

• Residue : efficient disposal of the remaining residues.

The principles of reduction, reuse, recycle, and recover shall, as far as is practicable, be applied to all waste streams, and thereby reduce the costs associated with its transportation and final disposal.

BSP follows the concept of “Duty of Care”, whereby generators of waste should be able to demonstrate that all reasonable steps were taken to ensure that their waste products were efficiently handled and disposed of. This procedure provides the means to meet “Duty of Care” responsibilities and for minimising waste.

2.2 Waste Reduction

Reducing waste generation improves financial performance through lower materials consumption and reduced disposal cost. BSP's approach to waste reduction is based upon the following general principles:

• minimise stocks and reduce the possibility of deterioration or obsolescence;

• procure non-hazardous products where possible;

• substitute with less hazardous materials;

• recycle materials and encourage a local recycling industry;

• repackage damaged containers or replace packaging for return to suppliers, where possible, rather than considering such as waste for disposal;

• seek "buy-back" arrangements with chemical suppliers for return of surplus chemicals;

• provide adequate storage facilities, particularly on temporary locations, to minimise stock deterioration / segregate oil based product from non-hydrocarbon material in separate drum or sumps.

• pursue use of bulk (re-usable) containers to minimise numbers of waste drums.

Opportunities to achieve significant waste volume reductions for some E & P wastes are limited, because their volumes are primarily a function of activity level (e.g. volume of drilling muds and cuttings is generally a function of the number of wells drilled and their depth). Nevertheless, opportunities do exist for some reduction; and efforts should be made to exploit them (e.g. chemicals, packaging, garden waste, paper).

Further guidance can be found in:

EP95-0390 Waste Management Guidelines, Shell International Exploration and Production.




2.3 Waste Classification

In the absence of defined legislation in Brunei Darussalam governing the classification of waste streams, BSP has defined the following broad categories of waste:

• Hazardous waste (2)

• Non-hazardous waste

• Industrial waste

• Office Waste

• Domestic Waste

These categories can be divided further into sub-categories. Each waste stream and arrangements for handling and disposal in BSP is described in more detail throughout the reminder of this document. A summary of the general waste streams and their handling and disposal arrangements is given in Appendix 1.

The classification is consistent with Shell International criteria described in:

EP95-0391 Classifying Waste, Shell International Exploration and Production.

2.4 Waste Segregation

Handling and disposal of waste is more effective if different types of wastes are kept separated and concentrated as much as possible prior to deciding on the final destination. Examples of this approach are:

• oil contaminated water and sludges should not be mixed with non-oil contaminated materials;

• waste chemicals should not be placed into the same skips as industrial waste. They should be separately stored in labelled containers to eliminate the contamination of other waste products, therefore minimising the bulk requiring special disposal;

• segregation of domestic from garden refuse to optimise the use of compactor trucks and opportunity for recycling; and

• scrap metals should not be mixed with rubbish or other non-metalic scrap.

2.5 Record Keeping

The maintenance of proper records of all disposal activities is an essential component of meeting the requirements of BSP under the concept “Duty of Care”. In addition such records provide:

• a basis for environmental impact studies around the waste disposal sites;

• an opportunity to review past practices and suggest modifications to procedures where necessary;

• information which may be useful in planning site abandonment and possible restoration measures;

• an opportunity to demonstrate to the public and government authorities that the waste disposal sites are being properly managed to prevent any problems occurring in the future.

• confidence associated with reliable records should help prevent any future liabilities against Brunei Shell Companies.

• verification to third party certifiers on proper waste disposal as per requirement of ISO14001.

• essential information for internal and external environmental performance reporting.

2 The term "Hazardous Waste" has been used to cover materials with the potential to damage humans or to have a negative impact on the environment. In other jurisdictions, the terms "special waste", "chemical waste" and "toxic waste" are also used.

Note, however, that competent authorities around the world have developed a number of definitions for hazardous waste which are inconsistent and, in some cases, incompatible with each other.




Disposals of non-routine waste and all hazardous waste shall be controlled through the use of the BSP Waste Disposal Form. A copy of the Waste Disposal Form and the standard procedure for its completion and use is given in Appendix 2.

Both the asset holders of waste disposal sites and the originators of waste shall maintain a record of all disposals. A central record of waste disposal shall be maintained in HSE/5 division.

Offshore Oil Record Book: A particular requirement for offshore operations is recording of all oily wastes, in order to conform with Marpol Annex 1 (Marine Pollution Law), which has been ratified by Brunei Darussalam. The collection, transport and disposal of waste oil from offshore installations (including platforms, mobile drilling units and vessels) shall therefore be logged in an oil record book kept on the installation. This includes any discharges of oily wastes to sea.




3 . H A Z A R D O U S W A S T E

3.1 Introduction

Hazardous waste is waste which because of it's quantity, physical, chemical or infectious characteristics, has the potential to cause harm to human health or the environment when improperly handled, stored, transported, treated or disposed of.

It may be difficult to identify if waste falls into this category given that data on its composition may not be available or its treatment is not available in Brunei. If in doubt, contact Environmental Affairs department, HSE/5, for advice.

In general, hazardous wastes include;

• asbestos and certain man-made fibrous material (when it is in loose form)

• toxic chemicals

• clinical / medical waste

• sewage sludge

• oily waste

• oil based muds & cuttings

• sludge / scale contaminated with heavy metals and NORM

• laboratory waste

• waste that contains any component deemed to be either toxic, corrosive, harmful, irritant, carcinogenic, explosive, flammable and mutagenic.

Disposal of hazardous waste is controlled through the use of the BSP Waste Disposal Form (WDF) - refer Appendix 2. This form is to be used for all hazardous wastes arising from BSP, other Brunei Shell Companies and their contractors.

The originator of the hazardous waste shall initiate completion of the WDF. This form shall be signed in turn by the asset holder of the designated waste disposal site to signify agreement to the disposal, the driver of the vehicle used for transportation of the waste, and the supervisor of the designated waste disposal site before and on completion of the disposal.

The initiator is to seek advice and approval from HSE/5 department prior to consignment of hazardous waste to disposal sites.

3.2 Asbestos

The handling and disposal of asbestos waste is regarded by BSP as an HSE Critical Activity. The originator is responsible for the safe removal and consignment of asbestos waste from the worksite to it's final disposal.

Asbestos removal is a high risk activity and shall only be carried out by specialist contractors who can demonstrate technical capability and experience in these activities. All asbestos removal work shall be carried out in accordance with :

BSP-02-Standard -1634 : Asbestos & Man-made Mineral Fibre (Module 34)

BSP-02-Procedure-1622 : Permit To Work (Module 03).

Materials that contain asbestos include : cement roof sheets, insulating boards, pipe lagging, gaskets. All asbestos waste must be double-bagged in plastic and clearly labelled as "asbestos waste".

All personnel involved in the handling process shall wear appropriate PPE (including disposable coveralls, safety shoes, half face mask fitted with a NPF 20 cartridge, gloves and goggles). Asbestos wastes are to be transported to the K-37 landfill site, where a dedicated asbestos cell exists for depositing the material. Disposal shall be carried out in accordance with the instructions of the worksite supervisor and with the procedures given in Section 8.4 of this document.




All persons engaged in work which may give rise to exposure to fibrous asbestos should be considered for medical surveillance at the discretion of the Occupational Health department, HML/8. The contents and frequency of both pre-placement and subsequent medical examinations should be determined by HML, taking into account the duration and regularity of the work.

3.3 Chemicals

Chemical wastes include any surplus, off-spec or contaminated chemicals.

A wide range of chemicals are used in BSP, including for production operations, drilling, engineering, maintenance, well operations, utilities, estates management, laboratories, hospitals and clinics. The range of products used is broad. From all of these activities chemical waste and surpluses arise. Further details on the management of chemicals from selection and procurement through to handling, transport and storage are provided in :

BSP-ACT-Guideline-1653 : Chemical Management Guidelines (Module 19).

Before deciding whether a chemical is actually a waste requiring disposal, every effort should be made by the generator department to determine whether or not it can actually be re-used.

All chemical wastes shall be referred to Environmental Affairs, HSE/5 department for advice regarding handling and disposal. Disposal is controlled by the BSP Waste Disposal Form which shall be completed by the originator for all consignments. This MUST include a detailed description of the chemical waste type and it's composition.

Note 1: Under the new Production Chemicals Supply contract, all surplus production chemicals are to be returned to the supplier.

Arrangements for handling and disposal of chemical wastes (in particular those arising from offshore) are summarised in Appendix 3. The flowchart gives details on the requirements for the preparation, handling, transportation and final disposal to approved disposal site. The roles and responsibilities of staff involved in the waste chemical handling (from waste generator to the waste disposal site asset holder) are also included.

Note 2: All chemical drums with residue contents greater than 5 litres shall be sent to the STL/21 yard for temporary storage i.e. pending advice from HSE/5 department.

Drums containing less than 5 litres shall be sent directly to CIC Environmental Services for cleaning and crushing prior to disposal. Shipment of all such drums must be accompanied with a consignment note.

Attention should be drawn to the Workfloor Instruction Card (WIC) or Material Safety Data Sheet (MSDS) to ensure that the correct precautions are taken in handling of chemical wastes. It is essential that ALL chemical waste containers are properly labelled using the label shown in Appendix 4 (Waste labels can be obtained via HSE/02.

All waste chemicals are sent to the STL/21 yard in Kuala Belait where the condition of containers and labelling will be checked, and consignment notes/ shipping manifest verified. If there are any concerns, the waste will not be accepted and will be returned to the generator.

Waste chemicals are stored in a dedicated shed in STL/21 yard, before either dispatch to CIC Environmental Services facility nearby for processing (under separate contract agreement) or dispatch to a dedicated treatment/disposal facility overseas.

Collection and transportation of the chemical wastes shall comply with :

Land Transport Manual - standards for vehicles TMS0439 and for drivers TMS0711.

3.4 Paints / Thinners / Solvents

Waste thinners and solvents shall be decanted into 205 litre drums prior to transportation to the STL/21 yard in Kuala Belait. The drums shall be in a good condition, i.e. not damaged or corroded, to ensure that none of the contents are spilt during handling or transit. These drums shall be securely placed and fastened down within open top containers for transportation and clearly labelled using the required Waste Label (Appendix 4).

Drums of waste thinners and solvents shall be sent to STL/21 yard, following procedures given in Section 3.3 for chemicals. Depending on the properties of the waste material, they will be either processed at CIC Environmental Services or stored in the STL/21 yard pending shipment overseas for incineration at a dedicated waste disposal facility. A Waste Disposal Form must be completed.




While awaiting collection, the drums should be stored in a well ventilated area to minimise the risks of inhalation of potentially dangerous odours, and the risk of fire.

Waste paints should be sent to K-37 landfill site for disposal and accompanied with a Waste Disposal Form.

Often large numbers of paint tins are generated during maintenance activities onshore and offshore. Efforts should be made by generators to ensure that paint tins are empty. Where volumes remain they should be either decanted into a 200 litre drum, or allowed to solidify in the tin itself. Discarded paint tins should be placed in an open container along with other miscellaneous wastes and disposed of as general waste in BLUE industrial waste skips or nylon sacks.

3.5 Laboratory waste

Waste laboratory chemcials are to be stored in a dedicated location in the SQI/2 laboratory, pending advice from SQI/2 and HSE/5 on disposal arrangements. Depending on the nature of the waste, it will either be sent to CIC Environmental Services or stored until such time as there are sufficient quantities of chemical wastes to warrant export to a special treatment facility overseas.

3.6 Pigging wastes

Pigging activities include monitoring / inspection / scraping of pipelines. Wastes generated during these activities can consist of wax, sludges, scale and oily water. These materials are generally oily and also have the potential to be contaminated with mercury and Naturally Occurring Radioactive Material (NORM) - also referred to as Low Specific Activity (LSA) material.

Material collected from pigging activities shall be collected in an open container. Ensure that the container is protected from rain to avoid overfilling the container. It is essential for Total Petroleum Hydrocarbon (TPH) and mercury content to be analysed prior to seeking disposal advice from HSE/5 division. See also section on oily liquids/sludges, mercury and NORM contaminated wastes (Sections 3.7, 3.8 and 3.9).

3.7 Oily Liquids / Solids

Oily liquids /solids are generated mainly from oil tanks or vessels maintenance, pits, drains, cellars and 'pigging' activities. Smaller quantities arise from bilge water and also from repairs of mechanical, automotive equipment and transformers.

Contractors of Brunei Shell are mandatorily required to send their waste oil to CIC Environmental Services , details of which are provided in Section 8. The control of disposal of oily liquids / solids is exercised through the BSP Waste Disposal Form.

The activity executor shall develop and deploy detailed work instructions which comply with this standard for activities in which oily liquids / solids waste is generated and stored prior to disposal.

3.7.1 Waste Oil: Waste oil shall be collected either in drums or vacuum truck and shall be sent to CIC Environmental Services Sdn. Bhd. for treatment.

The waste oil consignment to CIC Environmental Services shall be accompanied with the BSP Waste Disposal Form. For Brunei Shell companies, this WDF shall be approved by the HSE/5 department before delivery of consignment to CIC Environmental Services. For waste oil collected in drums, a Consignment Note (Appendix 5) will also be required stating place of origin, type of waste oil and the correct number of waste oil drums.

For waste oil delivered in drums from offshore, the waste generator must specify the exact number of drums containing waste oil as these are often sent together with empty drums to the STL/21 yard. Waste oil contained in drums must be labelled (Appendix 4) stating the type of waste oil to be disposed. (Waste labels can be obtained via HSE/02).

The driver of the vehicle MUST report to the supervisor of CIC Environmental Services with his Waste Disposal Form prior to discharging at the facility. As CIC Environmental Services is a private company, treatment of waste oil will be charged to the waste generator on tonnage of waste oil delivered.




Offshore, oil which leaks from engines and plant should be retained within drip pans and discharged into a main slop tank fitted with an oil / water separator. Alternatively, oily water or oily wastes can be discharged to platform sumps. Oily water discharged from the tank should not exceed 15 mg/l oil in water. The residual oil within the tank should be pumped into 205 litre drums for treatment.

Offshore Oil Record Book: A particular requirement for offshore operations is recording of all oily wastes, in order to conform with Marpol Annex 1 (Marine Pollution Law), which has been ratified by Brunei Darussalam. The collection, transport and disposal of waste oil from offshore installations (including platforms, mobile drilling units and vessels) shall therefore be logged in an oil record book kept on the installation. This includes any discharges of oily wastes to sea.

3.7.2 Used Cooking Oil Used cooking oil from onshore clubs and offshore mess kitchens shall be collected into 200 litres drums or discharged into the crude oil sump pit. Drums of used cooking oil should be clearly labelled using a Waste Label and handled in a similar way to waste oil described above. All shipments shall be accompanied by a BSP Waste Disposal Form. Box 3 of WDF - approval is not required.

3.7.3 Oily Water Locations which have oil-water separators and pits shall have their oily water emptied regularly by a vacuum tanker. Similarly, bilge water from ships, works boats and any tank cleaning activities shall be collected by vacuum truck for disposal. The HSE/5 department shall be contacted for advice on disposal of consignments of oily water. Depending on the nature of the oily water and capacity at SCOT, an option is to treat it in the Terminal. If this is not possible, the oily water is to be sent to CIC Environmental Services Sdn. Bhd.

All consignments of oily water are controlled through the use of the BSP Waste Disposal Form.

3.7.4 Oil Drums Oil drums either empty (or partially full) shall be sent for treatment to the drum washing / crushing centre at CIC Environmental Services. A completed Waste Disposal Form is required for drums containing oil. A Consignment Note only is required for empty drums.

All drums, which may contain residues of oil shall be sent, with their closure caps fixed to avoid spillage. These drums shall be labelled stating place of origin and type of waste oil. Waste labels (appendix 4), can be obtained from HSE/02.

After drum washing/rinsing the empty drums are crushed before being sent for recycling to a scrap metal contractor. Cleaned oil drums which are still in good condition are issued free of charge for re-use e.g. re-drumming purposes.

3.7.5 Oily Sludges Oily sludges from tank bottoms, pipeline pigging, vessel maintenance and drain cleaning shall be collected in containers appropriate to the volume generated (e.g. vacuum tankers, skips, drums) and sent to the Oily Solids Handling Facility (OSHF) in SCOT. Generators are to complete a BSP Waste Disposal Form.

When sufficient volumes have accumulated, it will be batch treated by specialist contractor. Present arrangements are for this to be processed via the Sg. Bera Remediation JV Company facility at SBHB site.

POP/1, as custodian of the OSHF shall maintain records of all types, volumes and sources of wastes desposited into and removed from the OSHF.

3.7.6 Contaminated Soil. The HSE/5 division shall be contacted for advice on dealing with contaminated soil, whether it be spill clean-up, or as part of programmes of decommissioning and abandonment. Various options exist, depending on the volume of contaminated material, nature of contamination, location and environmental sensitivity and clean-up requirements.

In some cases, excavation and transport to the Oily Waste Handling Faclity will be appropriate. In other circumstances, soil washing or in-situ bio-remediation methods may be appropriate.

BSP-02-Guideline-007 : Contaminated Site Management Guidelines




3.8 Mercury

Some vessels, piping and fittings on BSP and BLNG facilities may contain accumulations of mercury compounds in sludges or residues. Vessel inspections, maintenance and construction activities may require removal of filters and other piping equipment where mercury may be deposited.

Particular attention should be given to locations where mercury normally arises, such as vessels, valves and pipeline sections positioned immediately after major pressure or temperature drops (up to -15oC). Also at guard beds and coalescence filters specifically constructed to remove mercury or fine hydrocarbon mists from gas streams.

All personnel involved in either equipment disjointing, cleaning, maintenance, and scraping of contaminated material are required to give great care and attention during work execution. Mercury can be harmful to people if taken in at above exposure/tolerant levels through: inhalation (mercury vapour), cut/wounds on the body and ingestion due to poor hygiene & cleanliness practices.

Local work instructions / procedures should be followed alerting to potential presence of mercury and arrangements to protect worker health & safety. An example procedure providing guidance on the HSE precautions to be taken when handling potentially mercury contaminated material is:

Mercury handling and disposal guideline for Ampa-6 and 9 campaign activities

The following procedures should be followed as a minimum:

General Site Works

• Prior to commencement of work in an area potentially contaminated with mercury, the area should be fenced off with 'CAUTION' barrier tape. There should be a minimum level of people inside the fenced area, hence staff that have no specific task shall not enter this area.

• Minimum Personal Protective Equipment (PPE) requirements are PVC gloves, PVC aprons, Disposal type coverall, Steel toe ‘Wellington’ boots (leather boots are not recommended), Safety glasses with side guard or goggles, Half-mask respirator with Hg-P3 cartridge. Consult occupational health division HML/8 for further PPE advice.

• Prior to disjointing a vessel or a pipe, a drip tray shall be placed beneath the joints to be broken. This is to collect any spill and sludge that is likely to be generated.

• If the vessel / pipeline is to be removed prior to cleaning, all inlets / outlets are to be sealed prior transporting them . The items are to be clearly labelled "Refrain from opening of the vessel/pipe" to avoid possible exposure to onshore crew.

• All PPE and tools used shall be washed thoroughly with water before a person is permitted to leave the work site. Hence, no possibility for spreading of contaminants.

• The wash water from the work site shall be collected into a sump tank for offshore facilities and into a sump pit for onshore projects.

• All disposable PPE items are to be collected from staff before leaving the work area (fenced in) and kept in sealed bags for disposal. Only then, used materials can be disposed off into BLUE industrial waste skip.

• Where confined space or vessel entry is required, this must only be done AFTER vessels have been completely soaked, cleaned and drained. Follow

BSP-02-Procedure-1622 : Permit to Work Procedures (Module 03)

BSP-02-Procedure-1646 : Vessels, Pipelines and Equipment (Module 08)

The following additional precautions MUST also be taken:

Mercury level in the air (inside vessel) has to be tested prior to entering. If mercury vapour concentration is < 0.05 mg/m3, it is safe to enter providing appropriate respirators are worn. Seek assistance from HML/8 or BLNG laboratory to sample mercury vapour concentration.




Sampling for mercury

Samples of sludge, wax, scale and water MUST be taken for mercury analysis. A minimum of 2 samples are to be taken. Sludge / solids samples are to be placed in glass bottles. Liquids samples are to be placed in Teflon coated bottles. Dispatch samples to SQI/2 or BLNG laboratory for Mercury analysis. Containers and sampling advice available from the production chemistry laboratory SQI/2, or BLNG laboratory.

Waste disposal

SOLIDS

• Mercury level <10 mg/kg dry mass, dispose of as either oily waste (if analysis confirms this), or as general industrial waste into BLUE skips.

• Mercury level >10mg/kg dry mass requires special handling and disposal precautions, as follows:.

Mercury sludge shall be mixed with cement and properly solidified in a suitable container prior to disposal at BSP's solid waste disposal site at K-37. Mercury sludge shall be mixed with cement to the ratio of 1:2. Added to the cement is Calcium chloride (not > 5 % of the cement weight) as a binding agent. It is advisable to conduct a small volume solidification trial to test bonding of cement and sludge. Where necessary, increase cement ratio until a strong solidification mass (monolith) is achieved. Contact STL/2 or HSE/5 for advice.

Each container containing solidified mercury shall be labelled with a stencilled plate specifying the following information:

Drum reference number: 1 of X

Mercury Concentration: XX mg/Kg Hg

Origin: e.g. AP-XX, Vessel No. XXXX

Date: dd./mm/yyyy

Disposal of solidified mercury shall be accompanied with approved BSP's Waste Disposal Form.

Note: In the absence of mercury re-processing facilities in SE Asia, discussions are ongoing with waste management companies in Europe to handle mercury wastes from Brunei Shell operations. Whilst solidification methods are suitable for small volumes, alternatives are being sought for the larger quantities of mercury contaminated filters anticipated from BLNG in the future.

LIQUIDS

• Mercury level < 0.005 mg/l, liquid from the vessel/pipes, then waste liquid can be drained into drip pan for disposal

- via sump tank for offshore platforms

- via local sewage treatment works (JKR) or SCOT produced water line for onshore facilities

• Mercury level > 0.005 mg/l, liquid from vessel/pipe shall be diluted with copious water, prior draining into drip pan for disposal with other effluent streams as above.

Contact HSE/53 and complete BSP Waste Disposal Form to seek authorisation for disposal of mercury contaminated waste liquids BEFORE any planned effluent discharge.

Note: Brunei Government has proposed a draft set of Effluent Discharge Standards, which must not be exceeded. For Mercury this is 0.005 mg/l to sea, estuary or inland water.

BSP-02-Standard-1635 : Environmental Legislation and Quality Standards (Module 50)

In the absence of Mercury recovery facilities in Brunei and the current small volumes of mercury liquid waste generated, dilution and discharge to sea is considered an acceptable environmental disposal solution. To date there has been no evidence of liquids containing mercury levels > 0.005 mg/l. This guidance will be reviewed in light of changing mercury levels detected in effluent streams.

Mercury amalagam waste from Dentistry:

Small volumes of mercury amalgam waste are also generated by the Dental Department (HML/9) in Panaga Hospital. Once sufficient quantities have accumulated, an arrangement exists with the British Army Medical Corps to send to a re-processing facility in the UK via the British Armed Forces. Further information is available from HML/9.




3.9 NORM / LSA scale

Low Specific Activity (LSA) scale is calcium / barium sulphate / carbonate which is co-precipitated from produced and reservoir waters, together with radioactive elements which occur naturally at trace levels in the reservoir. This is commonly referred to as Naturally Occurring Radioactive Material (NORM). The radionuclides become concentrated in the scale thus making it radioactive.

LSA scale typically appears within the well fluid handling system in E&P operations. Deposition is heaviest in areas of turbulence - bends, valves, restrictions and also where sudden temperature or pressure reductions occur - chokes, separators, coolers. Other areas are tubing strings (especially tailpipe), liners (below the packer), wellheads and manifolds. It can also appear in the service water system and pig wax.

A comprehensive survey of potential NORM arisings in BSP was undertaken in 2001 with analysis by experts from Royal Dutch Shell Laboratories Amsterdam (KSLA). Samples were taken of sludges, scale, sand samples, pipeline and tubular scrapings from thorughout BSP. The survey concluded that concentrations of NORM arisings in BSP are very low compared with E&P activities in many other parts of the world. The data also verifies previous conclusions from earlier studies in BSP.

The actual BSP NORM / LSA scale analysis results belong to the lowest values measured in the KSLA E&P NORM database (all samples measured were less than 0.02 bq/g). As such, none of the samples analysed have to be classified as radioactive according to Shell International, or regulatory standards in other jurisdictions.

Currently, the issue of NORM / LSA in BSP is therefore not considered significant for waste disposal or occupational exposure.

Follow-up surveys will be undertaken in the future via SQI/2, HML/8 and HSE/5 to verify these data and advice.

BSP NORM data report - Nuclear Measurement Techniques of Shell International Chemicals - Geert Jonkers, KSLA Amsterdam, 17/09/2001 (available from SQI/22)

3.10 Drilling Muds and Cuttings

Drilling muds and cuttings is a general category which includes both muds and cuttings, and waste drilling fluids (including completion / stimulation fluids, brines, acids and cements). Whilst not all drilling muds & cuttings are hazardous, they are all discussed in this section for completeness.

According to SIEP waste classifications:

• Water based muds (WBMs) and cuttings are classified non-hazardous products but are per se non-toxic,

• Oil based muds (OBMs) and cuttings are classified as hazardous products and toxic,

• Synthetic based muds (SBMs) and cuttings are classified as hazardous products but are per se non-toxic.

The well services and well engineering department (TSW) shall develop and deploy detailed work instructions which comply with this procedure for activities in which drilling muds and cuttings waste is generated and stored prior to disposal. TSW contractors are also responsible to treat and dispose of their wastes to environmentally acceptable standards.

Offshore disposal of muds and cuttings is to be undertaken in accordance with ;

BSP-09-Guideline-1724 : Offshore Drilling Muds and Cuttings Disposal Principles and Management Guidelines.

This follows an environmental assessment of the Brunei offshore marine environment and provides guidelines for disposal in different areas according to environmental sensitivity and priority protection. It allows seabed disposal of WBMs and ester based SBMs. OBMs and other SBMs (e.g. olefins and paraffin based) are not allowed to be disposed offshore.

Onshore disposal of muds and cuttings is presently under review to establish the most environmentally acceptable option. For the moment, the following arrangements apply:

• WBM drilling fluids are disposed of to the Mumong Sewerage Treatment Plant, under a contractual aggrement between the operators (Public Works Department - JKR) and BSP's land drilling contractors. The fluids must meet certain standards (e.g. for Total Suspended Solids) before JKR will accept them.




• WBM cuttings are disposed of to the K-37 landfill site where they can usefully be used for capping the landfill. Because of this, no charge is levied providing the cuttings meet a dryness criteria of < 10% water content. If this is exceeded and the cuttings are too wet, the standard charging system applies.

• OBM fluids and cuttings are disposed of to the Oily Solids Handling Facility in SCOT, where they are temporarily stored pending batch processing/treatment by contractor. Present arrangements are for such materials to be treated via the Low Temperature Thermal Desorption plant operated by the Sungai Bera Remediation JV Company. This is a dedicated oily waste treatment process set-up to remediate the Sg. Bera Holding Basin site.

3.11 Clinical / Medical Wastes

Clinical / medical waste generated within hospitals and medical establishments may be hazardous or offensive if not dealt with properly. Such wastes arise at the Panaga Hospital and offshore clinics. The procedures defined below provide a general framework for those involved in the handling, storage and disposal of clinical waste and seeks to promote satisfactory standards wherever clinical waste is encountered.

• All staff involved in the handling of clinical waste shall wear suitable protective clothing and receive training to make them fully aware of the potential hazards;

• Clinical waste shall be collected routinely and not allowed to build up. It shall be disposed of at Panaga Hospital;

• Clinical waste shall be separately stored and correctly labelled and be easily distinguishable from other types of waste by use of thick gauge colour coded plastic bags (Yellow bags are used internationally for the containment of clinical waste.);

• Dedicated yellow coloured “sharp boxes” shall be available at key locations where needles, syringes and small quantities of medical wastes ariase (eg wards, clinics, labs, consulting and treatment rooms)

• All clinical waste shall be double-bagged in heavy grade polyethylene plastic sacks of a minimum 200 microns, and sealed for safe disposal;

• Clinical waste from offshore locations shall be stored in a sharp box and carried personally by HML Medic Representative to Panaga Hospital for disposal. BSP Waste Disposal Form to be completed (Box 1). No approval of HSE/53 is required i.e. Box 3 of WDF.

• All categories of clinical waste shall be incinerated;

• Certain categories of clinical waste, such as that emanating from pathology laboratories require autoclaving prior to incineration;

• Trolleys and carts used for transporting clinical waste shall be specially designed to minimise harbourage of bacteria and pests;

• Clinical waste shall be disposed of by incineration in a purpose built plant to ensure complete burn out to acceptable emission standards (in accordance with specifications provided in BSI:3107:1973;

• Care must be taken with the handling and disposal of residuals, fly ash, and non-combustibles as they may contain both organic compounds and heavy metals;

• BSP Contractors that wish to use the disposal facility at Panaga hospital should contact HML/0 for approval before delivery.

Particular attention shall be given to minimising the risk of ‘stick injury’ from incorrectly segregated and contained “sharps”.

The general procedures for personnel protection, which shall be followed at all times are:

• hold sacks by their closure end and wear heavy duty gloves to protect hands. Sharps have been known to pierce the sides and bottoms of polypropylene containers;

• pick up sharps containers by their handles and wear heavy duty gloves. Do not use the other hand to support the bottom of the containers;

• wear standard protective footwear;

• avoid bodily contact with bags of clinical waste and wear an industrial apron or leg protectors; and




• when clearing up body fluid, eye protectors, disposable gloves, overalls and mask shall be worn if there is a risk of the operator’s skin becoming contaminated. A person who cuts him or herself or has an accident, however small, shall immediately inform his supervisor and retain, if possible, the item that caused the injury to enable the nursing staff of the hospital to identify possible infection. Any contaminated clothing will have to be put into a yellow bag for incineration.

• a regular full course of anti-tetanus injections must be considered for all persons involved in handling clinical waste.

All clinical wastes are incinerated at a dedicated facility at Panaga Hospital. Arrangements also exist to use the incinerator at Suri Seri Begawan Hospital in Kuala Belait if the need arises.

3.12 Sewage sludge

ONSHORE:

The majority of BSP's houses and offices are connected to the local authority’s sewer system. However, some office areas and much of the BSP's rented housing are not connected to the sewer and utilise septic tanks.

Sewage sludge accumulates in septic tanks and they shall be desludged every two years, or sooner if necessary. PPA/32 is responsible for ensuring the desludging of septic tanks at BSP's offices and rented houses, EME/33 for BLNG tanks and ROS/3 for Refinery tanks.

This waste stream is to be collected and transported, using vehicles and drivers which comply with the requirements of Land Transport Manual - standards for vehicles TMS0439 and for drivers TMS0711, to the designated disposal site. Sewage sludge collected from septic tanks shall be discharged from vacuum tankers at the vehicle discharge point west of oxidation ditch No. 2 within the Mumong Sewage Treatment Plant.

This arrangement is conditional that the sludge is free from plastic and bulky materials that can damage the sewage pumps. Accordingly, STL/32 shall ensure that the vacuum tanker contractor uses a suitable gauge screen over the suction hoses when emptying sludge from septic tanks.

Solid materials generated from septic tank cleaning shall be disposed at K-37 landfill site.

OFFSHORE:

All sewage and sullage (waste water from wash basins and showers) shall be collected in a treatment tank which discharges into the sea via a pipe below sea level to minimise any odour problems and pathological infection. Treatment of the tank contents shall be carried out. This shall comprise microbiological decomposition of the organic content followed by the automatic dosing of chlorine into the sewage prior to its discharge.

Attention shall be paid to maintenance and the correct calibration of automatic equipment to ensure adequate treatment. Failure to do so may result in the generation of conditions prejudicial to health for staff involved in operation and maintenance of the equipment, and an environmental nuisance from bad odours.




4 . I N D U S T R I A L W A S T E

4.1 Introduction

Industrial waste is defined as any non-hazardous operational waste (general waste). It includes:

• Scrap metal

• Batteries

• Plastic & Cardboard packaging

• Drums / containers

• Wooden pallets

• Glass and fluorescent lighting tubes

• Construction & demolition waste

• General refuse from offices and operational activities

These are discussed on more detail in the sections below.

4.2 General Arrangements

BSP uses three types of container for general industrial waste - BLUE skips, black rubbish bags, white heavy duty nylon sacks (mainly for offshore locations) - only inert industrial waste shall be placed in them. Approximately 100 skips, each of 13m3, are in use. The maximum permitted load is 2,000kg.

A general industrial waste collection service is provided by a contractor of which STL/32 is the contract holder. All non-recyclable industrial waste in skips and waste sacks is transported to the K-37 soild waste landfill site.

The standards for this collection service are as follows:

• Prior to disposal in bulk, inert industrial waste shall be collected and stored in the containers (skips and sacks) which are located in close proximity to the worksite. Other types of waste such as scrap, waste oil and chemical / hazardous waste shall be segregated and collected in separate containers for separate disposal;

• Skips are provided at a number of onshore locations in the Seria, Panaga and Kuala Belait areas. These shall be checked at least twice per week and those that are more than half full shall be removed for emptying;

• Skips are provided on larger offshore facilities such as installations, drilling rigs, work barges and some other vessels. Offshore facilities with living quarters must have one skip available for general waste. Other types of wastes shall be segregated and collected in separate containers.

• At locations which may not have enough space to accommodate a skip, white heavy duty industrial polyethylene waste bags are provided. These include small mobile offshore facilities, such as workbarges and workboats involved in construction, maintenance and survey work;

• Other types of wastes e.g food waste or scrap metal shall be segregated and collected in separate containers ;

• Skips and waste sacks on offshore facilities shall be collected twice per week, whether full or not, by service vessels on the ‘milk run’ to minimise any potential nuisances from odour or pests. They are off loaded at KB Wharf (STL/2) for collection by the contractor for final disposal. Wastes shall be segregated and collected in separate containers for disposal;

• Service vessels are organised by STL/1 to whom enquiries over service provisions should be directed;

• During transportation, skips shall be covered (nets or tarpaulins) and sacks shall be properly fastened to prevent spillage and windblowing of litter;

• Skips and vehicles shall be regularly cleaned and maintained to minimise any nuisance from odours;




• All industrial waste in skips and waste sacks is to be transported to the designated solid waste disposal site at K-37 landfill. Drivers are to report into the site and to follow site instructions as given by staff. This will include following the designated routing and disposal at the designated area of the site.

• Regular inspections are to be undertaken by the Company Representative to ensure that the service is being delivered at a satisfactory level and to identify opportunities for improvement. This includes weekly inspections of industrial sites and KB Wharf;

• All land transport activities shall be carried out using vehicles and drivers which comply with the requirements of Land Transport Manual - standards for vehicles TMS0439 and for drivers TMS0711;

• If the contractor finds that inappropriate waste streams have been placed within the skips the matter should be brought to the attention of the Company Representative so that the necessary corrective action can be taken.

All the above standards will be co-ordinated by STL/3.

4.3 Scrap Metal

Scrap metal shall be separated from other waste streams and placed within an open top container, such as a barang box, for collection and transport.

A scrap metal removal contract is controlled by STL/22. The scrap metal is accumulated at the following storage points, KB Wharf, SCO Construction Yard, STL Main Yard at NIA and at BLNG, prior to uplifting by the contractor to his own storage yard.

A BSP Waste Disposal Form is not required, but all departments generating scrap metal shall send the consignment to the nearest STL/22 scrap storage yard under a BSP Consignment Note (Appendix 5). Small items should be stored separately, possibly in barang boxes or other suitable containers for intermediate storage and transportation. No other types of wastes e.g wood or paint cans shall be mixed with scrap metal.

Storage and collection of large items shall be discussed in advance with STL/22. Scrap metal delivered to STL/22 shall not be mixed with rubbish or other non-metallic scrap. Mixed materials will not be accepted and the originator shall arrange for the other materials to be stored and disposed properly as described in this procedure. In some cases, scrap may not be acceptable to the scrap dealer, and in the event of doubt or difficulty, advice from STL/22 should be sought.

Before scrapping large and complex metal items (eg offshore platforms and structures) Asset Managers and project engineers are requested to consider opportunities for re-use, or alternative application, (eg artificial reef creation). Contact HSE/5 division for advice.

4.4 Batteries

Batteries can be divided into the following broad categories:

Recyclable: All large wet type waste lithium batteries, lead acid batteries and NiCad batteries are stored with STL/22. When sufficient numbers have accummulated, they are sold to a supplier, manufacturer or recycling company, as appropriate.

Non-Recyclable: Non-recyclable batteries namely dry cell batteries and small dry sealed lithium or cadmium batteries shall be disposed of as general waste.

The general disposal procedure for each battery type is given below.

Dry Cell Batteries:

Waste dry cell batteries are NOT RECYCLED and shall be placed in thick double polyethylene bags (rubbish bags) and placed in domestic rubbish bins or industrial skips (standard blue skips) for removal from site and disposal at the K-37 solid waste disposal site.

Lithium / Cadmium Batteries:

Lithium / cadmium batteries should be handled with care. They should never be opened or burned. There are two general types of lithium / cadmium batteries each of which has different disposal routes. These are:




Small sealed type:

Small sealed lithium / cadmium batteries are NOT RECYCLED. This type is used in electronic equipment (cameras, wrist watches, etc.). They shall be placed inside double polyethylene bags (rubbish bags) and placed inside domestic rubbish bins or industrial skips for removal from site and disposal at the K-37 solid waste disposal site.

Large wet type:

Large wet type lithium batteries which are used in power back-up systems for electronic (with electrolyte circuit boards and similar applications) are RECYCLED in accordance with the following procedure:

• They shall be stored in a well ventilated dry area and away from direct sunlight (lithium batteries can catch fire, explode or cause burns, if allowed to get too hot, or ortherwise crushed, recharged, disassembled)

• The batteries shall be fully discharged before disposal. Do not short circuit the lithium battery. This may produce high temperature and subsequent cell rupture;

• Each terminal shall be protected with suitable electrical insulation prior to placing inside a double polyethylene bag (rubbish bag) and then placing them upright in a rigid box, secured to prevent movement;

• The packages shall be sent to STL/22 at NIA using the appropriate BSP Consignment Note;

• STL/22 shall store the batteries in the scrap yard until a commercial sized consignment has accumulated. The accumulated batteries are then sold.

Lead Acid Batteries:

This type of battery is commonly used in transport vehicles and power back-up systems. They are RECYCLED in accordance with the following procedure:

• The originator shall not drain the electrolyte (acidic solution inside the battery);

• Waste lead acid batteries shall be sent to STL/22 at NIA in a rigid box under the cover of the appropriate BSP Consignment Note; and

• STL/22 shall store the batteries in the scrap yard until a commercial sized consignment has accumulated.

Nickel-Cadmium Batteries:

There are two general types of NiCad batteries; “snap-on” and “block”. They are usually rechargeable and contain a hazardous alkaline electrolyte, which can cause irritation if splashed onto the skin or into eyes. Should liquid electrolyte come into direct contact with the skin or eyes, flush with copious amounts of water and then wash with warm soapy water.

The “snap-on” type are usually sealed (no electrolyte draining ports) and are commonly used in two-way hand-held radios and mobile phones. The “block” type NiCad battery is equipped with draining ports for the electrolyte.

All waste NiCad batteries are RECYCLED in accordance with the procedure below:

• The batteries shall be fully discharged before disposal. Do not short circuit the NiCad battery as this may produce high temperature and subsequent cell rupture;

• Each terminal shall be protected with suitable electrical insulation prior to placing them inside a double polyethylene bag (rubbish bag) and then placing the bag upright in a rigid box and securing them to prevent movement;

• The packages shall be sent to STL/22 at NIA using the appropriate BSP Consignment Note;

• STL/22 shall store the batteries in the scrap yard until a commercial sized consignment has accumulated.

4.5 Empty Drums / Containers

Metal and plastc containers are used for a wide range of lubricants and chemicals used in the Company. Drums and containers are considered "Empty" when they contain less than 2.5 cm of residue in the bottom, or less than 3% of their original contents. For 205 litre drums, the "5 litre rule" generally applies:




• Drums containing >5 litres of residues are considered as oil/chemical wastes and should be sent to STL/21 yard (follow guidance in Sections 3.3 or 3.7).

• Drums containing <5 litres residue are considered "Empty" and should be sent directly to CIC Environmental Services for washing. Metal drums are subsequently crushed and sent for scrap metal recycling. Plastic containers are cut-up and sent for solid waste landfill at K-37, there presently being no facility identified in Brunei or neighbouring parts of Borneo for plastics recycling.

4.6 Packaging

The majority of BSP's purchases are packaged in a range of containers and packaging materials. Every effort should be made during procurement to maximise the opportunities for returnable packaging and thereby minimise the quantity of waste that has to be disposed.

All packaging materials that cannot be returned to the supplier shall be recycled whenever possible. There are presently limited opportunities for recycling of packaging materials in Brunei, given the absence of companies willing to handle these materials. Consequently, most non-recyclable packing is disposed of at the solid waste landfill site at K-37.

Wooden pallets shall be re-used wherever possible, particularly at onshore storage locations. It is preferable to wood chip broken pallets, rather than dispose of to landfill. Contact estate maintenance division PPA or HSE/5 division for advice.

Cardboard and plastic materials shall be deposited into the BLUE industrial waste skips (or white nylon sacks for offshore locations) for collection and disposal to K-37 landfill. Opportunities are presently being sought to include cardboard packaging within the waste paper recycling scheme (there has been reluctance from local companies to receive cardboard wastes for recycling to date).

Skips shall be provided with a net/cover and the nylon waste sacks adequately secured to prevent materials being windblown. The use of waste compaction equipment to reduce the volume of waste products awaiting collection should be installed where practical. Where used, the facility will usually require fresh water wash down facility, drains, and fire fighting equipment.

No packaging material should be thrown over board at offshore locations. Staff found to be engaging in such activities shall be cautioned.

Advice on correct disposal methods and opportunities for recycling of packaging should be obtained from HSE/5 division.

4.7 Light Bulbs, Glass and Fluorescent Tubes

At present there are no arrangements for recycling of light bulbs and glass. Used bulbs / glass shall be placed in a carton box prior to disposal into skips or industrial nylon sacks and prior to collection and disposal to the approved solid waste landfill site at K-37. This disposal does not require a Brunei Shell Companies Waste Disposal Form.

Flourescent tubes shall be sent to a lamp crushing unit at STL/22 yard at NIA. Used flourscent tubes shall be placed in their original packs and secured onto a wooden palette. A BSP Waste Disposal Form is required - completion of box 3 is not required. While crushing, lamps are sprayed with water in a special crushing chamber. Chemical bonding materials are added to absorb the volatile compounds. Only after having gone through the process are crushed lamps bagged in thick gauge plastic bags for disposal to K-37 landfill site.

4.8 Blasting Medium

BSP has replaced the use of Copper Slag with Garnet as the preferred blasting medium. Garnet is an inert material and causes no known adverse effects in the marine environment. However, initiatives to recycle this material should be encouraged. Where possible, Garnet debris and waste are to be collected in gunny sacks and placed in barang boxes and sent for disposal at K-37 landfill site. BSP Waste Disposal Form is to be completed prior to sending onshore for disposal.




5 . O F F I C E W A S T E

5.1 Introduction

Office waste comprises:

• Used stationery and other waste paper ;

• Plastic and cardboard packaging materials

• Printer and copier toner cartridges

5.2 Waste Paper

BSP uses large amounts of paper and generates a substantial quantity of waste paper. Efforts to encourage minimisation of waste paper and improve collection and recycling arrangements are being driven by the office services department, FOS. Waste paper is currently collected and sent for shredding and baling at a new Shredding Centre. The Shredding Centre is located at the rear of the BSP head office building in the ex-PPA nursery hut. Collection of waste paper from all BSP and BLNG offices will be carried out by FOS department contractor.

Dedicated blue coloured waste paper recycling bins are located throughout the main office building. Green bins (660 litre capacity) are provided at specific locations for each department outside of BSP headquarters.

At offshore locations, waste paper shall be collected in dedicated bins that are labelled "Waste Paper - for recycling only.' When the bins are about 3/4 full, they shall be emptied into bin liners before putting them into nylon sacks for transportation onshore. The nylon sacks shall be labelled as Waste Paper with the name of the platform clearly marked. All waste paper bags shall be unloaded at KB Wharf only and stored in a designated waste paper recycling container before collection by FOS contractor.

Papers should be free of clips, staples and plastic materials before depositing into waste paper recycling bins. Office cleaners are responsible for emptying the waste paper bins into gunny sacks and depositing the sacks in the bulk containers provided. Office workers have the responsibility to ensure that no waste paper is deposited into personal waste bins.

Shredded waste paper at the Shredding Centre will be baled and sold to a local recycling company. Temporary storage of bales is also available at the ex-explosives store in Anduki, pending accumulation of sufficient quantities prior to collection. FOS is responsible for maintaining records of waste paper quantities stored and recycled.

5.3 Toner Cartridges

Toner cartridges are used in laser printers and photocopying machines. Toner is essentially powdered carbon which is harmless to the environment, but can cause skin irritation so should be handled with care.

BSP has established a recycling scheme, which is managed by STL/22, whereby toner cartridges are returned to the suppliers. When employees change a toner cartridge it shall be repacked in its original container or wrapped in paper or placed in a used and sealed envelope. It shall be dispatched to STL/22 through the internal mail service. STL/22 will store the cartridges until sufficient quantities have been accumulated to warrant collection for recycling.

5.4 Computers

Most written off computers from BSP have historically been disposed of to landfill, though small numbers have been donated to local schools for re-use. Recently, BSP has identified a suitable computer parts recycling centre in Singapore. Consignments of written off computers which cannot be easily re-used will in future be sent for recycling via this route.

Asset holders who propose computers to be disposed of shall submit a “written-off form” to SBS/15. These forms are available from SBS/15 or STL/2. In consultation with the generator, SBS/15 will decide the method of disposal for these computers i.e. whether for donation, sale or scrap. Computers destined for scrap shall be sent to the STL/2 yard at NIA. Prior to delivery to scrap yard, asset holders of computers shall notify STL/221 and prepare an inventory list of computers for scrap.




Final arrangement of scrap computers for recycling will be handled by SBS/15 and STL/221.

5.5 Miscellaneous Office Wastes

General office waste comprising of non-recycleable, or difficult to recycle materials, shall be deposited in waste bins located around offices and emptied by cleaning contractors into BLUE industrial skips or nylon sacks (as appropriate to location). These will be collected on a routine basis for disposal to the K-37 landfill, as per arrangements described in Section 4.2.




6 . D O M E S T I C W A S T E

6.1 Introduction

Domestic waste is the term given to waste products generated within residential dwellings. It mainly comprises packaging material (plastic, paper, glass, metal items and cardboard), food waste and garden waste.

6.2 General Arrangements

The arrangements and standards for the collection, storage, transportation and disposal of domestic and garden waste are as follows:

• The collection of domestic waste from BSP's residential properties in Seria, Panaga, and Kuala Belait is undertaken by a contractor for whom HML/4 is the Contract Holder;

• The collection of garden waste from Brunei Shell Companies’ residential properties in Seria, Panaga, and Kuala Belait is undertaken by a contractor for whom PPA/3 is the Contract Holder

• Residents and employees of clubs and schools are responsible for the initial segregation and storage of domestic and garden waste;

• The waste products are to be placed in suitable containers and/or plastic sacks;

• The Contract Holder shall ensure that employees of the waste collection contractor are provided with suitable personal protective equipment and have received appropriate training to make them aware of the potential health hazards;

• Domestic waste shall be collected every day from recreational clubs and offices and every two days from housing. Garden waste shall be collected at least once per week;

• These waste streams are to be collected and transported, using vehicles and drivers which comply with the requirements of Land Transport Manual - standards for vehicles TMS0439 and for drivers TMS0711, to the designated solid waste disposal site at K-37;

• The Contract Holder shall carry out routine verifications of the contractors performance in residential areas and offices and clubs and ensure that the service is being provided to a satisfactory level; and

• Personnel employed on the service shall be competent to understand and complete the required documentation, understand the hazards involved in the waste being handled and be able to communicate with originators of waste.

The contractor shall collect waste in accordance with the following conditions:

• Carry out waste collection in accordance with the programme agreed with the BSP Contract Holder. This will include collections every day from BSP's clubs and offices and every second day from residential dwellings;

• Deploy compaction vehicles for domestic waste and tipping vehicles for garden waste all of which shall comply with:

Land Transport Manual - standards for vehicles TMS0439 and for drivers TMS0711.

• Open topped vehicles used for the collection and transportation of garden waste shall have their cargo netted / covered and properly secured in accordance with the requirements of the Land Transport Manual when moving on the public highway;

• Payloads will be maximised to reduce journeys to the designated tipping site;

• Vehicles shall be regularly cleaned to minimise any potential nuisance from odours to residents and other road users;

• Staff shall be provided with the correct PPE in accordance with the requirements of:

BSP-02-Standard-1628, Personal Protective Equipment (PPE)

• Regular medical checks shall be provided to all staff, at least every six months, and inoculations for tetanus and hepatitis B are to be valid.




Materials with which the contractor is unfamiliar, or uncertain about, should not be collected until advice has been provided by the Contract Holder concerning the most appropriate way to handle and dispose of the material.

The Contract Holder shall ensure that:

• contractors and residents are familiar with, and are complying with their respective responsibilities;

• weekly inspections of residential areas, offices and clubs are being carried out to ensure that the service is being provided to a satisfactory level; and

• any queries from residents concerning the service, such as issuing advice concerning the handling of difficult wastes, are answered promptly.

Information concerning the domestic and garden waste collection services can be obtained from HML/4 for domestic and PPA/3 for garden waste.

Vehicles containing domestic and garden waste may only deposit their consignments at the BSP approved solid waste landfill site at K-37.

On arrival at the disposal site the driver of the disposal vehicle shall report to the clerk and inform him of the waste type and its source. The driver shall then follow the instruction of the worksite supervisor and tip the waste in accordance with the given instructions.

6.3 Domestic Refuse

Residents are responsible for the initial segregation and storage of domestic waste.

Domestic waste shall be placed in a bin or plastic waste sack, and garden waste piled next to it or contained within plastic sacks for collection. The waste containers must be left in a convenient place with good access for collection.

The bin:

• shall be made of a durable material such as metal or plastic and be in a good condition, i.e. not corroded or holed to minimise problems caused by rodents and insects;

• shall not be overfull to avoid the risk of injury to the waste collection personnel and to minimise the potential nuisance of windblown litter; and

• shall be regularly rinsed and disinfected by the resident to minimise risks to the health of personnel collecting the waste and to reduce the problems of odour and pests.

Sharp objects such as broken bottles should be carefully wrapped, and where possible placed within a cardboard box or container to avoid cuts and puncture wounds to collection staff.

6.4 Garden waste

Garden waste is material such as grass cuttings, branches and foliage resulting from the maintenance of gardens and Company owned public areas. This material should, wherever practicable, be wood chipped and/or composted. It is preferable to recycle organic garden waste in this way raher than sending to landfill, where it uses up valuable landfill space, shortens the lifespan of the landfill and costs money to dispose of. Responsibility for this activity is PPA/3.

6.5 Food waste

Food waste generated within canteens, galleys and clubs shall be separated from any packaging materials and disposable mess room equipment such as plastic cutlery and cups. Food waste shall not be stored or simply be thrown over board. In addition to being unsightly it can cause a risk to public health through the breeding of pests.

Onshore, all food waste shall be placed in double black plastic bags and deposited in BLUE industrial waste skips for disposal to landfill.

Offshore, all food waste shall be passed through a macerator and disposed of into the sea via a pipe which discharges below sea level. Such material shall pass through a 25 mm screen.




6.6 Aluminium cans

Aluminium cans should be deposited in dedicated recycling bins located at various points in the offices, clubs and offshore locations. Once full, the bins should be emptied into heavy duty plastic bags and deposited into the recycling skip at Panaga Club, pending collection by recycling contractor. Continued vigilence and effort is required to maintain proper segregation and collection of aluminium cans.

7 . V E S S E L S A N D P L A T F O R M S

7.1 Introduction

All waste products, both solid and liquid, generated by manned platforms and by vessels involved in construction and maintenance activities require proper handling and disposal.

All waste streams should be correctly segregated and stored in separate containers in accordance with the instructions contained in this document. Storage facilities such as skips, refuse bags, barang boxes, and drum cages are normally provided to manned platforms and construction and maintenance boats by STL. Additional facilities can usually be made available where a legitimate need is identified. These shall be used at all times.

All waste products generated offshore are collected by service vessels on the ‘Milk Run’ at least twice weekly so as to minimise potential problems with pests and odours and a lack of storage space. If this level of service is found to be insufficient appropriate measures should be taken by the master, through the Company Representative, such as requesting additional storage facilities from STL/21, or increasing the frequency of collection via STL/1.

All waste products collected by the service vessels are to be unloaded at Kuala Belait Wharf for intermediate storage prior to disposal. Only when it is operationally unavoidable shall these waste products be unloaded at Muara. Operations at KB are supervised by STL/211 and by STL/213 at Muara

7.2 Waste Handling from Offshore Platforms and Vessels

A BSP Waste Disposal Form shall be completed for all hazardous waste materials, such as chemicals and oils, transported to shore. All other wastes, such as domestic waste, shall be accompanied by a Shipping Manifest /Consignment Note in accordance with departmental procedures.

The transporter shall not accept any waste for which the documentation is not correct.

Hazardous wastes which are not the subject of routine disposal or for which the exact contents is not known shall not be sent for disposal until the disposal route has been defined by HSE and the asset holder of the disposal site has given approval to receive the waste.

The master on the service vessel shall ensure that the correct documentation accompanies the cargo to be transported to shore. Waste products shall not be handled in the absence of the correct documentation.

In addition, all drums and other packaging containing waste oil and chemicals shall be identified by the use of appropriate waste labels which draws attention to the potential hazards. Tapes for hazardous and oily waste are available to order from STL/1.

7.3 Waste Handling from Unmanned Platforms

Amended procedures to those outlined in the above section shall be adopted for use on unmanned platforms.

The Senior Operation Supervisor will ensure that the following is undertaken:

• all personnel visiting unmanned platforms will be made aware of the requirement for following responsible waste handling practices;

• signs in English and Malay should be provided at each unmanned platform instructing personnel to use the waste storage facilities provided and not to throw waste overboard. Staff found to be engaging in such activities shall be cautioned;

• industrial skips or large nylon waste sacks will be supplied, via the area boats, on each unmanned facility for the storage of waste. The type of waste storage facility provided will largely be determined by the type of winch / hoist available on the platform;




• waste containers will be collected on a regular basis by the area boats to minimise potential nuisances associated with pests and odours. Supervisors visiting unmanned platforms should routinely report on the status of the waste containers and whether they require emptying;

• the nylon sacks are not purpose-made for this use, therefore care should be taken not to damage them when disposing of sharp and abrasive materials such as wire and metal;

• no food waste shall be placed in the nylon sacks or skips as this will encourage the generation of conditions potentially prejudicial to health. Personnel shall be responsible for removing all food waste and associated packaging from the unmanned platform and placing it in the appropriate containers upon their return to the manned platforms;

• care should be taken by the operators of the winches / hoists to ensure that the nylon sacks are securely fastened and that the skips are covered with a net when transferring on and off the boats to avoid the problem of windblown litter;

• sump pumps should be regularly checked and mainained and, if necessary, operated to avoid sumps becoming too full which can result in the escape of hydrocarbons during periods of rough weather and high swell.
