Section 4 – Relevant Environmental Legislation and Guidelines

The Leighton Contractors (Asia) Limited shall comply with the following Hong Kong SAR ordinances and regulations, which cover, or have some bearing on, the handling, treatment and disposal of waste.

4.1 Ordinances and Regulations

4.1.1 Waste Disposal Ordinance (Cap 354)

This ordinance prohibits any person from using any land or premises for the disposal of waste unless one has been authorized by or has obtained a license from the waste-disposal authority, the Environmental Protection Department.

4.1.2 Waste Disposal (Chemical Waste) (General) Regulation, Enacted Under Waste Disposal Ordinance

This regulation has provisions to require any person who produces chemical waste to register with the Environmental Protection Department as well as to control the processing, storage, collection, transport and disposal of chemical waste. In additional, the regulation also provides for the licensing of waste collection, transport and disposal activities.

Chemical waste includes any scrap materials, or unwanted substances specified under Schedule 1 of this Regulation, if such a substance or chemical occurs in such a form, quantity or concentration that causes pollution or constitutes a danger to health or risk of pollution to the environment.

A person shall not produce, or cause to be produced, chemical wastes unless he is registered with EPD. Any person who contravenes this requirement commits an offence and is liable to a fine and/or imprisonment. Chemical wastes must be treated, utilising on-site plant licensed by EPD or have a licensed collector to transport the wastes to a licensed facility. For each consignment of wastes, the waste producer, collector and disposer of the wastes must sign all relevant parts of a computerised trip ticket. The system is designed to trace wastes from production to disposal.

This regulation also prescribes the storage facilities to be provided on site including labelling and warning sign. To minimise the risks of pollution and danger to human health or life, the waste producer is required to prepare and make available written emergency procedures for spillage, leakage or accidents arising from storage of chemical wastes, and provide employees with training for such procedures.

4.1.3 Land (Miscellaneous Provisions) Ordinance (Cap 28)

Inert construction waste may be taken to public dumps. The Land (Miscellaneous Provisions) Ordinance requires that a dumping licence be obtained by individuals,

Leighton Contractors (Asia) Limited Revision 2 03.04.2006

Paper copies are uncontrolled. The controlled version is on the Project Server

or companies, who deliver suitable construction waste to a public filling facility. The licence is issued by the Civil Engineering Department. When public dumping of such material is required, Leighton Contractors (Asia) Limited shall apply for the licence prior to disposal.

4.1.4 Public Health and Municipal Services Ordinance (Cap 132) - Public Cleansing and Prevention of Nuisances Regulation

This ordinance has provisions on the control of the discharge of hazardous material to sewers and for the control of littering. The ordinance prohibits placing or throwing any solid matter, mud or waste into public sewers or drains and also placing those substances in a location where they may fall into public sewers and drains. The ordinance also has provisions to require the owner or occupier of the land adjoining any street or place that is situated near a public sewer to exercise measures to prevent obstruction of sewers and drains caused by soil and waste.

4.1.5 Dumping at Sea Ordinance

The Dumping at Sea Ordinance requires that dumping permits are obtained by individuals or companies who deliver dredged/excavated marine sediment to designated disposal sites. The permits are issued by Environmental Protection Department under delegated powers from the Director of Environmental Protection. The permit shall be applied for as required.

4.1.6 Air Pollution Control (Open Burning) Regulation (CAP 311O) Enacted Under Air pollution Control Ordinance

This regulation prohibits or restricts the open burning in or at any place what so ever of any kind of material that may evolve air pollutants unless one has been authorised or obtained a permit from the Environmental Protection Department.

Open burning means the combustion of materials of any type outdoors without an enclosure, where the products of combustion are not directed through a chimney.

Open burning for the following purpose is prohibited: a) The disposal of construction waste b) The clearance of a site in preparation for construction works c) The disposal of tyres; and d) The salvage of metal.

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

the polluter pays principle.

The regulation requires the main contractor (of works with a value of $1 million or above) to make an application to the DEP within 21 days after of award of contract to establish a billing account. Once a billing account has been established the DEP will issue “chits” which will be used to record the disposal of waste at a designated waste disposal facility.

When delivering a load of waste to a designated waste disposal facility the waste hauler appointed by the account holder will be required to produce a valid “chit”.

4.1.8 Admission Ticket for Disposal of Special Waste at Landfills

Some waste will only be accepted at landfills with prior authorization from Environmental Protection Department under the Admission Ticket System. These waste include sludge/residue from sewage treatment plants, water works or industrial and commercial processes with a dry solid content of less than 30% but greater than 20% by weight for WENT & SENT, or greater than 15% for NENT, tyres and other wastes such as dewatered dredged material with a liquid content less than 70% by weight and contaminated material, etc. Admission Tickets are obtained by individuals or companies who deliver these special waste to designated landfill sites. The Admission Tickets are issued by Environmental Protection Department under delegated powers from the Director of Environmental Protection. The ticket shall be applied for as required.

Section 5 – Action

5.1 Introduction

Under the Leighton Contractors (Asia) Limited Environmental Management System, waste-management options are categorized in terms of preference from an environmental viewpoint as:

avoidance and minimization (ie, avoiding or not generating waste through changing or improving processes, practices and design);
re-use of material, thus avoiding disposal;
recovery and recycling, thus avoiding disposal (although some form of reprocessing may be required); and
treatment and disposal, according to relevant laws, guidelines and good practice.

That hierarchy is used to evaluate waste-management options, thus allowing maximum waste reduction and often reducing costs. For example, by reducing over-ordering of construction material, waste is avoided and costs are reduced both in terms of purchasing the material and waste disposal.

5.2 Organization Structure for Waste Management

The overall structure of the project organization is maintained separately and identified by the project director for the project. Figure 5-1 shows the arrangement for the organization and lines of communication for waste-management issues.

The project environmental coordinator shall have responsibility for coordinating waste-management activities and initiatives.

5.3 Project Directory

The project secretary maintains a separate project directory that lists details of all key contacts from each of the main organizations participating in the project, including those with responsibility for the implementation of the Waste Management Plan. The directory is made available to project staff by posting on notice boards and/or via the project network (Leighton Asia Document Management System) or similar. The part of the directory relevant to waste management shall be included in Table 5.1 and 5.2 (including subcontractors) and shall include as necessary, names and telephone numbers of work relating to the Waste Management Plan.

site-clearance material;
excavated material;
contaminated soil;
marine sediment;
construction waste;
packaging waste;
chemical waste, and
general refuse.

The main activities that have potential to cause adverse environmental impacts from waste include site clearance, utility diversion, excavation works including substructure, manholes, pipeworks and drainage, marine piling works, marine excavation and laying of submarine pipeline, formwork and falsework, concrete works, wet trades and finishing works and fit-out, plant and equipment maintenance and general welfare arrangements for the workforce. The proposed mitigation measures to avoid or minimize the quantity of construction and demolition material generated during the project are described in Section 5.8 and in the control plan for waste and chemical management as detailed in Appendix A.

5.5.1 Site Clearance

Waste material may be generated from site clearance including existing vegetation and trees and surface infrastructure.

5.5.2 Excavated Material

Significant quantities of excavated material will be generated from activities associated with Permanent Aviation Fuel Facility. However, all of this material can be reused on site for purposes such as landscaping or to form bund walls.

5.5.3 Sand Surcharge Material

Significant quantities of sand material will be generated from activities associated with Permanent Aviation Fuel Facility. The majority of this material can be reused on site for purposes such as fill material to excavations and under the tanks. All efforts will be made to ensure that material surplus to requirements will be reused on other contracts.

5.5.4 Dredged Marine Mud

Marine sediment, which is the seabed deposit, is mainly generated from excavation/dredging of sediment/mud. It could be classified as contaminated and uncontaminated based on its contamination level with reference to Chemical Exceedance Level (CEL) laid down in Appendix A of the Environment, Transport and Works Bureau Technical Circular (Works) No 34/2002, Management of Dredged/Excavated Sediment, Environment, Transport and Works Bureau. Significant quantities of marine sediment will be excavated and disposed during the marine pipeline laying works from receiving jetty at Sha Chau to the on-shore Permanent Aviation Fuel Facility at Tuen Mun area.

5.5.5 Construction Waste

Construction waste comprises unwanted material generated during construction, including rejected structures and material, material that has been over ordered or is surplus to requirement and material that has been used and discarded. Waste will arise from a number of site activities throughout the construction period and may include:

Leighton Contractors (Asia) Limited Revision 2 03.04.2006

Paper copies are uncontrolled. The controlled version is on the Project Server

a) Concrete and Other Cementitious Material

Surplus concrete, concrete debris and cementitious material may result from:

general in-situ concrete works;
wet trades (eg, broken bricks and block, abandoned tiles);
material that has been over-ordered;
rejected material, and
washing out of equipment.

b) Timber

Timber waste may be generated from the fabrication and use of timber formwork.

c) Steel and Other Metallic Waste

The main source of steel waste and other metallic waste is off-cuts resulting from cutting and bending steel reinforcement, steel plates, pipe offcuts and sheet piles for temporary works and E&M fit-out works.

d) General Building Material

The main source of building material waste is surplus bricks, blocks and wall and floor finishes.

5.5.6 Packaging Material

Many types of material and components are delivered to site in cardboard, plastic or timber packaging.

5.5.7 Plastic Waste

The main source of plastic waste is plastic sheets for packaging of material and abandoned sealant cartridge equipment and plastic drink bottles.

5.5.8 Chemical Waste

Chemical waste is generated on site through the maintenance of plant and equipment or following spillage and may include:

scrap batteries or spent acid/alkali from their maintenance;
used lubricating and hydraulic oil from plant and equipment servicing;
used air, oil and fuel filters from machinery; – oily rags;
surplus paint;

5.7 Performance Targets

To facilitate assessment of the effectiveness of the waste-management measures, the following performance targets shall be adopted as far as practicable:

all excavated material will be sorted to recover inert portions (eg, soil and broken rock) for re-use on site or disposal to designated outlets (eg, public filling areas);
vegetation cleared on site will be stockpiled and used as mulch on landscape bunds;
all timber will be recovered on site for collection by a recycling contractor;
all metal will be recovered on site for collection by a recycling contractor; and
all cardboard and paper packaging (for plant, equipment and material) will be recovered on site, properly stockpiled in dry conditions and covered to prevent cross contamination by other construction and demolition material for collection by a recycling contractor.

5.8 Waste-mitigation Measures

The proposed mitigation measures to avoid or minimize the quantity of construction and demolition material generated during the project are described in the following sections and control plan for waste and chemical management is detailed in Appendix A. The proposed disposal arrangement is also listed and shall be confirmed with CEDD, EPD and FMC in due course.

5.8.1 Site clearance

Site clearance will take place during the execution of activities associated with Permanent Aviation Fuel Facility. Surplus vegetation and organic matter generated shall be stockpiled and used as mulch on the landscape bunds. During site clearance, the relevant requirements of the Construction Dust Regulations shall be adopted.

5.8.2 Demolition Material

Demolition material shall be segregated to maximize possible re-use and recycling. Bituminous material arising from the excavation of existing pavements may be re-used on-site for paving. Inert construction and demolition material may be re-used on site or disposed to public filling Tuen Mun Area 38 fill bank. Other material such as steel shall be recycled as far as practicable. Leighton Contractors (Asia) Limited shall examine further opportunities to use recycled construction and demolition material (eg, from the construction-and-demolition material recycling facility at Tuen Mun Area 38) on the site taking account of the latest available information and the requirements of Works Bureau Technical Circular 12/2002, Specifications Facilitating the Use of Recycled Aggregates.

5.8.3 Surplus Excavated Material

Substantial amount of surplus excavated material will arise from activities associated with Permanent Aviation Fuel Facility. About 50,992 cubic metres of surplus excavated natural material, such as fill material or rock grade IV & V of size less than 200mm, will be made to re-use that material on site or at other sites requiring fill material subject to actual site conditions.

Concrete waste excavated on site shall be sorted and used as armour stone over the pipe line where suitable material is recovered.

An estimated 274,000 cubic metres of Type I marine deposits generated will be disposed of in designated open-sea disposal areas, in accordance with the Particular Specification.

Excavated material shall be segregated from other waste to avoid possible contamination, therefore allowing re-use on site or at other sites that can utilize the material.

5.8.4 Marine Sediment

It is anticipated that about 274,000 m3 (in-situ) material requiring Type 1 open sea disposal.

Dumping permits shall be obtained for the disposal of surplus uncontaminated sediment at the open sea disposal facility.

The management of the marine sediment will be in accordance with the mitigation measures for marine sediment in Appendix A.

5.8.5 Construction Waste Material

The use of prefabricated components shall be considered to reduce the quantity of waste arising from the project. In general, construction waste shall be minimized by carefully planning construction activities to make sure resources are used efficiently and to avoid over ordering. Proper storage and handling procedures shall be used to minimize waste resulting from damage to material.

a) Concrete and Other Cementitious Material

Concrete for both temporary and permanent works shall be delivered to the site in mixer trucks. Depending on access arrangements the concrete shall either be discharged directly from the truck chute or by crane and skip. Concrete delivery shall be controlled to prevent spillage of the concrete. Cleaning out of the truck chute and mixer drum shall be into a designated waste skip or onto plastic sheeting. Waste concrete shall be allowed to harden and then shall be removed from the site.

To minimize waste arising from the use of concrete and other cementitious material, construction activities shall be carefully planned to make sure that resources are used efficiently and that material is not over ordered. When practicable, alternative uses for excess concrete shall also be identified. When disposal is unavoidable, material shall be collected and stored to avoid contamination such that it can be disposed of to a Public Filling Facility.

A target of less than 4.25% of the quantity of concrete waste expressed as a percentage of total quantity delivered have been set for this project to reduce concrete wastage.

Paper copies are uncontrolled. The controlled version is on the Project Server

b) Timber

Waste (e.g. timber from timber formwork/hoarding) arising from temporary works on site can be minimised by alternative forms of design and construction methods. The alternative forms of design and construction methods facilitate not only minimising temporary works and extending their lifespan to reduce waste, but also allowing the use of reusable or recyclable components. Proposed measures to reduce use of timbers in temporary works construction are:-

(a)
Consider how the design is constructed to minimise temporary works;
(b)
Consider alternative forms of design to reduce temporary works;
(c)
Check with contractor or experienced constructors the construction methods and materials that can reduce temporary works;
(d)
Choose temporary work materials that can be reused on other sites such as metal hoarding or metal scaffolding;
(e)
Consider the use of high-quality temporary components that can be reused and last longer; and
(f)
Allow the use of prefabrication or modularisation to minimise on site works that produce waste.

Leighton Contractors (Asia) Limited shall avoid, reduce or minimize the use of timber in temporary works construction as far as possible. Where the Contractor has to use timber for temporary works construction for one process/activity with an estimated quantity exceeding 5m³ or otherwise set by the FSR, he should submit a method statement to the FSR for agreement prior to commencement of the works. The method statement should include the justification for and the measures taken to minimize the use of timber in the temporary works. In addition, the Contractor shall provide a summary table, as attached in Appendix D, containing the description, justification and the estimated quantity for every work process/activity requiring the use of timbers for temporary works irrespective of the quantity of timber used.

Timber formwork shall be carefully dismantled to prevent damage. The timber shall be de-nailed, cleaned and stacked neatly for re-use. Timber hoarding shall not be used and the use of tropical hardwood is prohibited. Wooden pallets for material delivery may be returned to the supplier for re-use.

c) Steel and Other Metallic Waste

Steel waste will come from three main sources: reinforcing steel, steel sheet piles, and offcuts from the storage tank construction. All steel deliveries shall be offloaded using a crane truck. Steel material shall be lifted correctly, stored on timbers and stacked neatly to prevent damage.

Reinforcing steel shall be cut and bent to the approved bar bending schedules. Every effort shall be made to utilize the complete 12-metre length of reinforcing steel bar to minimize off-cuts. Checks shall be made to make sure that the reinforcing steel is cut and bent correctly to prevent errors and the need to scrap

Leighton Contractors (Asia) Limited Revision 2 03.04.2006

Paper copies are uncontrolled. The controlled version is on the Project Server

incorrectly-bent steel. Off-cuts shall be used to support rebar cages. All surplus steel shall be placed in a skip for recycling.

Steel sheet piles shall be handled correctly to prevent damage. The driving of a sheet pile shall be controlled to ensure maximum utilization of the entire length of the sheet pile. Sheet-pile off-cuts shall be re-used as much as practicable. Scrap sheet piles shall be stacked neatly on timber.

The steel storage tanks contain approximately 4,400 tonne of plate and structural steel, to minimize wastage of steel plate, cutting sheets will be prepared to match the available plate sizes of the supply mill.

Plates steel will be cut and prepared off site where possible. Structural steel for the roof trusses and walkways will be fabricated off site and fixed together on site. Piping isometrics and cutting sheets will be prepared to minimize the amount of off-cut pipework. Plate steel will be delivered to site by barge to minimize handling.

For other metallic waste once identified, recycling companies shall be sought when the quantity and quality of waste makes recycling practicable and cost effective.

d) General Building Material

Good housekeeping measures shall be adopted on site to minimize the quantity of waste that requires disposal. Those measures shall include the allocation of designated storage areas, making sure material is handled carefully by operatives and by implementing a stock management plan.

5.8.7 Packaging Material

*Collection frequency shall be reviewed based on the actual storage capacity of the waste facilities and minimum collection frequency may be required apart from stipulating collection only when the bin is full.

Surplus construction-and-demolition material shall be sorted on site into inert and non-inert material for disposal. Inert construction-and-demolition material shall be segregated on-site in order to maximize the recovery of re-usable and recyclable material. A system of work for on-site sorting shall be included to identify the source of generation, estimated quantity, arrangement for on-site sorting and collection, temporary storage areas, frequency of collection by recycling contractors or frequency of removal off-site. Consideration shall be taken to sort inert construction and demolition material at source to avoid double handling as far as practicable. Except for re-usable inert construction-and-demolition material, all other inert construction-and-demolition material shall be broken down into manageable size and removed off-site as soon as practicable to optimize the use of the on-site storage space.

As far as practicable, general refuse shall be segregated at source by the use of bins for different types of material.

5.10.3 Recycling

Arrangements shall be made with potential recycling contractors so that recyclable material sorted from the site is collected with reasonable care. The quantities of recyclable material shall be recorded before removal off site by the designated recycling contractor and details shall be included in the Waste Flow Table.

Appendix E Environmental Emergency Procedures

Environmental Emergency Procedures

Purpose

The purpose of the procedure is to describe the environmental emergency preparedness and response procedure for this site. Note that the Leighton Safety Management System addresses emergency procedures related to site safety eg, accidents and personal injury.

Scope

The procedure shall apply to emergency situations that impact on the environment such as spillage, rainfall.

Terminology

Nil

References

Site Safety Plan Corrective and Preventive Action Control Procedure (QMP 14.1)

Actions

General

The potential for an environmental emergency exists at this site due to the large number of different construction activities being carried out and the materials, plant and equipment being used. Additionally, natural events may create an environmental emergency situation that must be appropriately managed. These potential emergencies are addressed in this section as events which would trigger the implementation of environmental emergency preparedness and response procedures.

The following are types of potential environmental emergency that could arise at the site.

Fire

-
May cause the release of dust and toxic fumes
-
May produce contaminated run-off from water and chemical suppressants

Spill and Material Release

-
May cause surface water or marine water contamination via drains and channels
-
May result in release of flammable liquids and vapours capable of causing a fire and gas explosion hazard
-
May cause release of toxic fumes and liquids
-
May result in contamination of equipment and storage vessels.

Accident

-
May cause fire, explosion and spill
-
May result in the mixing of incompatible chemicals
-
May cause surface water or marine water contamination through the release of hazardous materials
-
May cause release of fumes or vapours into the atmosphere.

Natural Event

- Heavy rains that may result in flooding of channels and waterways

- Typhoons accompanied by high winds and heavy rain

- High winds may result in dust and flying debris

- Earthquakes.

Emergency Contacts

Emergency contacts and telephone lists are located on the safety notice boards located throughout the site. Telephone numbers and contact person lists are updated when necessary but will normally contain at least:

- Ambulance

- Hong Kong Police Force

- Fire Service Department

- Hospital

Spill containment and response

General requirements The main objective of spill containment is to minimize uncontrolled releases thus preventing soil and surface water contamination and protecting adjacent groundwater and marine water environments. The hierarchy of priorities when a spill occurs is:

- assess the situation and the likelihood of resulting injuries;

- stop further spillage if possible by shutting down pumps and valves;

- use radio to dispatch appropriate site equipment and personnel to the spill location for containment, control and cleanup;

- contain spilled material and cleanup

- document incident using corrective action request form, distribute and file;

- follow up with site training where appropriate;

- the area managers, project environmental coordinator or safety officer on duty will assess the situation, call the appropriate authorities if necessary and document the spill and cleanup.

Hazardous materials

The following hazardous materials are stored and handled on the site:

Location Material Storage Method
On-site Diesel fuel Liquid petroleum gas Cleaning solvents Engine oil Hydraulic oil Waste oil Above ground storage tanks Gas cylinders Tin cans Steel drums Steel drums Steel drums
Location Material Storage Method
Stores Miscellaneous chemicals such as Generally tin cans or plastic containers
DG Store Liquid petroleum gas Acetylene Gas cylinders Gas cylinders

Spill containment kit

The following list of typical items to be included in the spill containment kit (exact content to suit site requirements):

- UV resistant wheelie bin (220L) (To contain absorbed material for disposal)

-
2 50kg bag fibre containing 150L of compressed product (absorbent capable to absorb 130L per bag)
-
2 booms (100mm diameter in 1.2m and 3m lengths) (absorbent capable to absorb 14L/m of boom)
-
2 booms (150mm diameter in 1.2m and 3m lengths) (absorbent capable to absorb 31L/m of boom)

- 3 absorbent pillows (400mmx75mm) (absorbent capable to absorb 21L per pillow)

- broom

- spark proof shovel

- brush and pan set

- mask with filter

- goggles

- gloves

Liquid spills

Liquid spills are most likely in areas where plant and equipment is refueled or maintained, i.e. at the on-site storage tank.

Spillage of Oils

All permanent stores of oils and fuels are to be contained in a bunded area, thus reducing the risk of spills reaching water course or contaminated land. If a spill does occur, the spill will be dyked using booms or sandbags, sand or soil to contain the spill and to prevent it from entering the drainage system. Absorbent pillows, soil or sand is used to absorb the bulk of the spill. Contaminated material shall be stored temporarily in the Chemical Waste Store pending disposal off-site. Disposal of the resulting waste should be to an authorized disposal site via a chemical waste collector. The disposal site for solid chemical waste is usually the active area of a landfill (on application to the landfill operator) or to a chemical waste treatment facility. Spills involving flammable liquids shall be treated with extreme caution to minimise risk of injury and damage. Note that water should only be used to minimise fire damage and protect personnel. Excessive use of water can cause flammable liquids to spread over an extensive area.

Spills at the on-site storage tank

The on-site storage tank is to be kept in a bundled area to minimise risk of uncontrolled spillage. If a spill does occur, the spill is dyked using booms, sandbags, sand or soil to prevent it from entering the drainage system. Absorbent pillows, soil or sand is used to absorb the bulk of the spill. Disposal of the resulting waste should be to an authorized disposal site via a chemical waste collector. The disposal site for solid chemical waste is usually the active area of a landfill (on application to the landfill operator) or to a chemical waste treatment facility.

Solid spills

Solid spills are generally associated with material delivery, movement or waste disposal. These spills are usually the result of accidents or improper packaging of the materials involved and is generally cleaned up by the appropriate subcontractor. In the event of the subcontractor or carrier is unable to clear the spillage, e.g. due to injury, the spillage should be cleared taking all necessary precautions dependent on the nature of the material involved.

Training Drill For Spill Incident

A practice drill for a spill incident shall be carried out as early as practicable during the contract to confirm that procedures are operating satisfactory. The drill should involve all relevant key staff as detailed in this procedure.

Injury Treatment

During the course of an environmental accident or emergency, injuries should be dealt with in accordance with the procedures given on the safety notice boards and documented in the safety plan.

Procedure in case of fire

Note that no burning of waste is allowed on this site. In the case of a fire on the site, follow the procedures given on the safety notice boards and documented in the safety plan. Follow the relevant emergency services' instructions and directions regarding site evacuation and clean up methods.

Precautions and actions relating to rainstorms

Precautions are to be taken at any time of year when rainstorms are likely:

- silt removal facilities, channels and manholes should be maintained and the deposited silt and grit should be removed regularly;

- temporarily exposed slope surfaces should be covered, eg by tarpaulin;

- temporary access roads should be protected by hard paved or protected with crushed stone or gravel;

- intercepting channels should be provided (eg along the crest/edge of the excavation) to prevent storm runoff from washing across exposed soil surfaces;

- trenches should be dug and backfilled in short sections. Measures should be taken to minimise the ingress of rainwater into trenches.

Actions to be taken when a rainstorm is imminent or forecast

- Silt removal facilities, channels and manholes should be checked to ensure that they can function properly;

- open stockpiles of construction materials (eg aggregates, sand and fill materials) on site should be covered with tarpaulin of similar fabric;

- all temporary covers to slopes and stockpiles should be secured.

Actions to be taken after rainstorms

- Silt removal facilities, channels and manholes should be checked and maintained to ensure that they are working satisfactorily.

Post-emergency Procedures

Post-emergency procedures are designed to prevent recurrence, to cleanup and dispose of residuals, and to debrief personnel.

Prevent recurrence

The safety officer on duty shall take all necessary steps to ensure that a secondary release, fire, or explosion does not re-occur after the initial incident. Procedures carried out include:

-
inspection and monitoring of any equipment involved in the incident;
-
inspection of gas generation;

- isolation of collected waste materials.

All operations that are initially shut down during response to an incident are not reactivated until the project director or safety officer has given the signal to proceed.

Treatment and disposal of residual material

Once the emergency situation has ended the project director, safety officer or project environmental coordinator on duty initiates the cleanup and disposal of any residues. This shall take place as soon as practicable to avoid further contamination or incident recurrences. Liquid spills occurring within a containment area or sump are analyzed, treated and pumped or drained for appropriate disposal. Spilled liquids are cleaned up with absorbent pads or dry soil or sand and are disposed as Chemical Waste.

Personnel debriefing

The safety officer or project environmental coordinator conducts meetings with site supervisory staff and subcontractors to review preparedness, prevention and response activities. Based on this review, suggestions for revisions to the existing emergency and work practices are made to the project director and adopted if appropriate.

Incident, accident and injury reporting

Statutory accident, injury and incident reporting is carried out by the safety officer in accordance with legislation requirements and the requirements of the LCAL safety management system. The Project Environmental Coordinator shall record spills and environmental incidents not covered by the safety management system using the corrective or preventive action procedure QMP 14.1.
