1. INTRODUCTION

This document is GIC framework Waste Management Plan (WMP) for the Gas Pipeline emergencyrehabilitation programme. This WMP focuses on the construction phase of the project and formspart of GIC's Environmental and Social Management System (ESMS).

In accordance with the requirements of GGIC safeguard document Environmental ManagementFramework (Appendix 3, pages 40-41) the construction contractor is responsible for thedevelopment and implementation of the WMP for construction phase, based upon the frameworkprovided here in this document.

2. WASTE SOURCES AND STREAMS

The identified wastes fall into the following main groups of waste types:

* refuse-type solid wastes;* sewage wastes and other wastewaters;* inert construction wastes;* non hazardous construction wastes; and* hazardous construction wastes.

The Waste Inventory also covers the disposal/treatment options which will be used to manage thewastes generated during construction.

2.1 REFUSE-TYPE SOLID WASTES

These wastes will mainly be produced at camp with smaller volumes arising from personnel activityon ROW. The main waste management choices in Georgia for refuse-type solid wastes generated byconstruction workers are:

* Recovery/recycling;

* Incineration; and

* Landfill.

Non hazardous and hazardous refuse type solid wastes will be kept segregated from each other withhazardous wastes including medical type wastes, including unused surplus pharmaceuticals, fromfirst aid rooms.

The medical sub-contractor will collect medical waste in specially designated colour coded containersmade of plastic or cardboard, one of which at any time will be stored in first aid rooms until full. Oncefull the containers will be transferred by waste transport sub-contractor for storage and subsequentincineration.

In addition, recyclable and reusable refuse-type solid wastes will be segregated to facilitate re-useand recycling opportunities. These wastes include:

* Waste vegetables and vegetable matter from canteen;



* Waste paper, card and cardboard;* Plastics, excluding bottles; and* Glass bottles.

2.1.1 Incineration

There are advantages to be obtained from the incineration of solid refuse type wastes. These include:

* significant reductions in the volume of waste requiring landfill (80% - 90%);* reduction of risk of odour and vector borne diseases;* easier management and control;* less of a site aftercare problem;* incinerator may also be used to manage other wastes, which may not be acceptable in

landfill.

The main disadvantages with incineration are the increased initial capital cost and increasedmonitoring. In addition incinerator must be designed, operated and maintained to such a standard asto ensure acceptable air emissions. The incineration residues require landfilling.

It is considered that the advantages significantly outweigh the disadvantages and thereforeincineration of these wastes is the preferred option for the management of solid refuse type wastes.

2.1.2 Landfill

A certain landfill capacity will be required even if wastes are incinerated or composted as not allsolid refuse type wastes can be composted and incineration gives rise to residues which must beproperly disposed off.

Particular care shall be taken to minimise leachate generation and to ensure that leachate which isgenerated is collected, treated and disposed of in an environmentally sound manner.

2.1.3 Recovery/Recycling

Glass bottles will be segregated and returned to the supplier for reuse. Prime recyclables (eg paper,card, plastics, excluding plastic bottles, which will be incinerated) will, as far as is practicable, besegregated from domestic type solid wastes for recovery/recycling. These materials will be suppliedto the local community for reuse and recycling or to an approved third party facility.

Putrescible wastes from construction camp canteens may be provided to the local community to beused as pig feed. This material will consist of waste vegetable matter only which will be segregated atthe canteen kitchen level prior to serving of food following which the vegetable waste may becomemixed with animal products.

2.2 SEWAGE WASTES AND OTHER WASTEWATERS

Wastewater comprises all water from work sites including temporary facilities (e.g. constructioncamps) and water generated by subsidiary operations (e.g. vehicle and equipment washing), as wellas rainwater from certain areas such as vehicle maintenance areas, which may become contaminatedby hydrocarbons, silt, etc.



Wastewater does not include the water flowing through diversion drains or drains arranged as part oferosion-preventive measures unless contractor's activities have an effect on the water quality.

The waste minimisation principle will apply to wastewater management, i.e. water will be re-usedwhenever practicable, e.g. hydrotest water may be re-used in successive sections of the pipelinebefore treatment prior to disposal. All residual wastewater will be treated prior to final disposal.

2.2.1 Sewage Sludge

Sludge accumulating in the WTP and septic tanks, at the remote construction facilities, will beremoved when required as part of operational control of the WTP. Dependant upon water contentthe sludge will either be removed using mechanical heavy plant to a skip or pumped to a tanker fortransport to the CWAA and subsequent incineration.

2.2.2 Contaminated wastewaters

Oily waters and contaminated waters arising from vehicle refuelling yards, vehicle-washing facilities andvehicle maintenance yards will either be collected in below ground separation tanks or discharged viaoil/water interceptors.

Wastewaters from concrete batch plant (which are located at camp locations) washdown will bedischarged to plastic lined evaporation ponds. Water will be evaporated from these ponds and residualcement will be disposed to landfill.

Oil from the tanks will be pumped to tanker and transferred for subsequent incineration. Separated waterwill be sampled and analysed to ensure it meets environmental requirements prior to discharge to the sitedrainage system.

Oil contaminated rainwater collecting in bounding surrounding tanks on ROW will be pumped to tankerand taken to a bioremediation facility (approval from GIC to enable the use of a bioremediation facility isstill required). Oily-water or other contaminated water arising away from the camps or at thetemporary camps will be collected and tankered, to the major WTPs at the pump stations.

2.2.3 Construction Wastewater

Uncontaminated construction wastewater from trench pumping activities will be discharged to landin accordance with the Pollution Prevention Management Plan.

Contaminated construction wastewater will be collected by pumping to a tanker and disposed to thenearest water treatment facility for suitable treatment.

2.2.4 Hydrotest Water

The discharge of hydrotest water without additives is covered in the Pollution PreventionManagement Plan.

In the event that chemical additives are required hydrotest water will be deemed to be wastewaterupon discharge and will require treatment prior to discharge to prevent impact to surface waterecology.



In all cases, hydrotest water composition will be determined and relevant discharge applicationsfiled with the MoE specifying treatment standards, discharge locations and conditions, in accordancewith the applicable Georgian legislation.

2.3 INERT CONSTRUCTION WASTES

These wastes arise from the ROW and facility construction. The following types of inert waste areanticipated to be produced from these activities:

* Natural materials (soil and rock);* Contaminated soil;* Agricultural topsoil;* Worked stone other than natural stone that has been crushed/screened; and* Building materials.

The disposal of these materials which are likely to arise mainly as part of reinstatement are alsodiscussed in the Reinstatement Management Plan.

A hierarchical approach to the disposal of inert construction waste will be employed to minimise theamount of material requiring final disposal. This can be summarised as follows:

* Return excavated soil and rock to the trench during and following pipe laying activities asbackfill. Rock will be crushed and graded using mobile plant, where practicable.

* Use as construction material for other project construction needs such as maintaining accessroads. Added benefit that less additional aggregate material will have to be extracted from localsources.

* Allow local communities to utilise any excess rock, which may be left following reuse asspecified above. These materials will be supplied to the local authorities for subsequent re-use inthe local community. Suitable access to the materials will be agreed with the local authorities inconsultation with the community liaison team.

* Transport any further material to the nearest preferred spoil disposal pit.

The other types of inert wastes detailed above (excluding natural soil and rock) will be disposed inthe hazardous landfill once developed.

2.4 NON HAZARDOUS CONSTRUCTION WASTESA number of non hazardous wastes will be generated during pipeline and facility construction.

In summary the main non-hazardous construction wastes will include the following:

* Metals (including scrap metal, pipe cuts and wire);* Timber (removed trees and packaging materials);* Plastics (packaging materials);* Containers (steel and plastic);

Metals will be provided to the local community (if required) for re-use or stored until an appropriatelandfill has been established or recycled if a suitable facility becomes available (none available atpresent).



Small branches from felled trees will be provided to the local community for firewood and re-use, aswill redundant untreated wooden packaging.

In first instance, plastics materials will be recycled. Plastics materials, which are unable to berecycled, will either be provided to the local community for re-use (if suitable) or will be transferredfor storage prior to the development of a suitable landfill.

The following options will be used to handle waste containers (which contained non-hazardousmaterials):

* re-used by CONTRACTOR for storage (including waste storage if suitable);* returned to supplier (if possible);* supplied to the local community for re-use;* disposed to landfill as last resort.

2.5 HAZARDOUS CONSTRUCTION WASTES

These wastes will arise mainly from the ROW, initial facility construction and vehicle maintenanceyards. A number of hazardous wastes will be generated during pipeline construction. These include:

* liquid fuels;* lubricants, hydraulic oils;* chemicals, such as anti-freeze, anti-corrosion products;* paints and preservatives;* original containers for all above;* untreated sewage sludge;* contaminated soil;* spillage control materials used to absorb oil and chemical spillages;* machine/engine filter cartridges;* chemical residues from waste water treatment;* fluorescent light bulbs;* vehicle batteries.

The majority of the hazardous wastes listed above will be incinerated (when operational). Theexceptions to this are as follows:

* used lubricants will be return to the supplier;* containers for hazardous materials will be re-used by CONTRACTOR for storage of suitable

hazardous waste, returned to supplier (if possible) or crushed and sent to landfill;* aqueous liquid wastes will be treated at the main construction camp WTPs;. scrap construction wastes will be supplied to the local community or will be

incinerated/landfilled;* if asbestos containing materials are identified during construction they will be double-bagged

(coloured plastic bags) and stored in sealed drums and transported prior to disposal option.

The following hazardous wastes may be generated in small quantities and will be subject to specialhandling and management procedures:



* Explosives Waste: Waste explosives procured for use during the Project will be stored in their originaltype of container, but marked as waste. They will be handled and disposed of as recommendedby the manufacturer;

* Radioactive Waste: Radioactive waste will be returned to suppliers for appropriate management.

3. STORAGE AND HANDLING PROCEDURES

This section discusses the measures and procedures (prior to treatment and/or disposal), which will betaken to manage waste produced at construction site level (pump stations, camps, pipe yards, ROW)during construction activities and ensure a Duty of Care is maintained by CONTRACTOR with respect towastes for which CONTRACTOR is deemed the holder. The management measures are discussed in thefollowing order of priorities:

. Classification;* Inventories;. Handling;. Labelling;* Storage and Segregation; and* Transport/transfer of waste.

4. WASTE MINIMISATION, TREATMENT AND DISPOSAL

4.1 AVOIDANCE AND MINIMISATION

Avoidance and minimisation of waste has been studied as part of the wasteminimisation/treatment/disposal study. A number of materials and measures have been identified, whichpresent waste avoidance and minimisation opportunities. These opportunities can be summarised asfollows:

* The selection of non-hazardous replacements for hazardous materials would reduce the amount ofhazardous wastes requiring disposal (but may lead to a corresponding rise in the amount of non-hazardous wastes); and

* The quantities of non-hazardous materials used during construction can be reduced by bothselection of suppliers who use less packaging and the efficient use of materials.

4.2 REUSE/RECYCLE

Once wastes have been produced the first step in dealing with the wastes will be to endeavour to reuse orrecycle the wastes where possible to reduce the volume of waste, which needs to be treated or disposed.Materials will either be sent for reuse/recycling directly from the site at which the waste is produced orfrom the central waste accommodation area.

CONTRACTORs waste recycling programs comprise the handling and segregation of recyclable/reusablewastes (described in Table below) as outlined above.



Table 1: Reusable and Recyclable Wastes

Waste Reuse/Recycle methodWaste vegetable matter Waste vegetable matter ONLY may be provided to the local community to be used as pig feed.Waste paper, card and Provided to local community for reuse or to recycling plant in Tbilisi (approval required fromcardboard GGIC prior to use).Plastics (excluding Either sent to recycling plant in Tbilisi for chipping/granulating via the central wastebottles) accommodation area(approval required from GGIC prior to use) and/or provided to local

community for reuse.Glass Bottles Returned to supplier for reuse.Lubricating Oil Returned to supplier.Timber (trees and The high value timber that is felled to clear the ROW is the property of GGIC and will be sold,packaging) where possible, and the cash invested into the community investment program. Small trees,

branches and timber packaging (which can not be reused by CONTRACTOR) will be madeavailable for communities to use as firewood.

Inert construction A hierarchical approach to the reuse of inert construction waste will be employed. Anywaste remaining inert construction waste, which is not able to be reused will be disposed the nearest

GGIC preferred spoil disposal pit.Hydrotest water Re-used in successive sections of pipeline, before treatment prior to disposal.Metal If possible provided to local community for reuse or to a third party company for export and

recycling (approval required from GGIC prior to use).Containers (metal and Reused by CONTRACTOR for storage, returned to supplier or provided to local communityPlastic) for reuse (non hazardous materials ONLY).

4.3 TREATMENT AND DISPOSAL

In the event that the waste produced cannot be reused or recycled. It is anticipated that the followingwaste treatment/disposal methods will be employed:

* wastewater treatment;* physical/chemical treatment;* incineration; and. Landfill.

The treatment and disposal options, which will be used to manage each type of waste, is identified inthe provisional inventory. The following sections describe the waste treatment and disposal facilitiesavailable for use by CONTRACTOR.

4.4 USE OF APPROVED FACILITIES

There are currently no approved waste disposal facilities in Georgia.

In the event that any facilities are identified and which are subsequently approved by GGIC, wastemay be transferred for utilisation, treatment and/or disposal to third parties. Waste will only betransferred to third parties with appropriately permitted/licensed facilities capable of handling,utilising, recovering, recycling, treating and/or disposing of the waste in a safe and environmentallysound manner. Third parties facilities will be periodically audited to determine the suitability of thefacilities and whether transferred waste are being/have been managed appropriately.

Transfer of waste to third parties must be fully documented on Waste Transfer Forms.

4.5 CONTRAC TOR'S FACILITIES



The following sections describe the facilities, which CONTRACTOR will construct/install/developto treat and dispose of waste produced during construction in accordance with the contractrequirements. Any permits required for these facilities will be filed with the MoE as per thepermitting procedure.

4.6 WASTEWATER TREATMENT PLANT

The treatment plant should be capable of accepting a range of wastewaters including sewage effluentand oily water, with each type passing through a sequence of unit operations, such as oil removal,chemical treatment, biological treatment and suspended solids removal.

Portable toilets will be supplied at construction sites on ROW and at other short-term constructionfacilities, including pipe yards and camps under construction, with the exception of remote pipeyards, which will be serviced by below ground septic tanks and soak ways. Effluent from portabletoilets will be pumped to a tank on a specialist vehicle, which will service and move the toilets. Theeffluent will then be transferred daily to the nearest temporary worker camp for subsequent treatmentin the WTP. As a minimum, the discharges arising from CONTRACTORs construction facilitieswill conform to World Bank standards.

4.7 CENTRALISED WASTE ACCUMULATION AREA

The CWAA is an area for the accumulation of waste produced at all CONTRACTOR constructionsites prior to treatment and/or disposal at CONTRACTOR facilities or transportation to third partiesfor reuse/recycling, treatment and/or disposal. CONTRACTOR CWAA operators will receivetraining specific to waste management issues associated with the CWAA to ensure a high level ofcompetence. The CWAA will provide both storage and treatment facilities as follows:

* Storage prior to transfer for reuse, recycling, treatment and/or disposal;* Treatment via hazardous waste incinerator (prior to final disposal).

Note: waste provided to the local community for reuse/recycling, will be transferred directly to thecommunity from the waste-generating site and will not be transferred to the CWAA.

The CWAA will comprise the following:

* Be a secure compound;* Vehicle access road, turning area and waste offloading area;* Containers for segregated waste storage (including storage for incinerator ash);* Hazardous waste storage area;* Skip laydown/storage area;* Plastics/paper baler (to reduce the volume of plastics/paper prior to sending for recycling);* Office and changing facilities;* PPE store;* Eyewash and emergency shower;* Emergency equipment including fire fighting equipment;* Absorbents and over pack containers for dealing with leaks/spillages from containers;* Can crusher;* Bounded fuel storage;* Incinerator (for both refuse type waste and hazardous waste).

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00005 Page IO of 17


The CWAA will have concrete hardstanding, a number of roofed areas and be provided withseparate drainage, spillage control kerbs and sump. The hazardous waste store will be provided withsecondary containment and roofing.

Proper waste segregation will be maintained at all times, separate storage areas and suitablecontainers, including skips and drums will be provided to ensure continued segregation of waste.

Waste will be further sampled and characterised at the CWAA in order to determine treatability andacceptability for management by available methods in order to select the most appropriatemanagement method for any given waste.

4.7.1 Hazardous and Non Hazardous waste Landfill

A certain landfill capacity will be required even if wastes are incinerated as not all solid refuse typewastes can be incinerated and incineration gives rise to residues which must be properly disposed of.

Non-hazardous waste may be disposed of to either non-hazardous waste landfill, providing it isdesigned, managed and licensed according to directive requirements. Hazardous waste will bedisposed to a hazardous waste landfill.

4.7.2 Inert Construction Waste Disposal Pits

The disposal of any remaining inert construction waste, which includes soil and rock, is discussed in theReinstatement Management Plan (refer to the Reinstatement Management Plan for details).

4.8 TEMPORARY WASTE STORAGE

It is acknowledged by CONTRACTOR that a number of these facilities in particular the incineratorsand landfill will not be developed in time for the beginning of construction activities. Consequently,interim storage of the wastes produced will be undertaken at the CWAA, until suitable treatment anddisposal facilities have been developed.

5. TRAINING

CONTRACTOR will provide sufficient training to all staff to ensure that they are aware of therelevant aspects of the WMP and are able to fulfil their waste management roles and functions.Specific training will be provided to those employees identified in this WMP and with specificduties associated with waste management.

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00005 Page I I of 17


6. COMMITMENT

A Waste management plan, including a minimisation/ treatment/ disposal study shall be undertakenby the Contractor as soon after contract award as practicable. The study shall include legislativeframework, waste quantification, waste classification, waste minimisation, and arrangements forwaste handling, treatment and disposal. The objectives of the plan include: provide a summary of allrelevant regulations and restrictions, provide permit requirements for waste treatment or disposal,provide method statements for each element of waste handling, treatment and disposal, identify anythird party agreements, provide proposals to audit waste management operations, identify reasonableuse of materials to reduce waste, specify monitoring requirements to reduce visual impact fromwaste site, enforce strict duty of care on project managers and contractors, establish secure wastestorage away from watercourses, drains and aquifers and secure from vermin, prohibit uncontrolledburning or burial, identify requirements for environmental review of potential landfill andincinerator sites including site selection and proposed operation mode, provide monitoring andauditing procedures, identify provisions for inert waste, ensure all potential subsoil disposal sites aresubject to review and an ERA prior to their adoption, provide procedures for offsite disposal or longterm storage of contaminated material.

1. Introduction

This document is GIC framework Emergency Response Plan (ERP) for the Gas Pipelineemergency rehabilitation programme. This ERP focuses on the construction phase of the projectand forms part of GIC's Environmental and Social Management System (ESMS).

In accordance with the requirements of GIC safeguard document Environmental ManagementFramework (Appendix 3, pages 40-41) the construction contractor is responsible for thedevelopment and implementation of the ERP for construction phase, based upon the frameworkprovided here in this document.

2. Potential Incidents

This Plan considers the following potential incidents:

* Pollution by sediment runoff into potable / irrigation water sources* Spillage of pollutants (e.g. during refuelling or hydro-testing)

1.1 Pollutants

Potential pollutants from a facilities construction and testing project of this nature include:

* Diesel fuel, lubrication oils and hydraulic fluids, etc. from construction vehicles and plant* Miscellaneous chemicals (e.g. paint thinners, cement and concrete, hydro-test additives

including corrosion inhibitors, oxygen scavengers, antifreeze, biocides, dyes, etc)* Herbicides and pesticides* Construction wastes (packaging, welding rods, wood, etc.)* Special wastes (e.g. lead acid batteries, tyres, waste oils, spent filters, spent blasting grit,

waste epoxy coatings, contaminated soil, etc)* Silt suspended in runoff waters ("construction water")* Bentonite lost into a watercourse when borehole drilling* Sewage (if not adequately contained and treated)* Contaminated land (pre-existing)* Hydrostatic test water (disposal)* Noise* Air emissions (from vehicles and plant), and* Dust.

Preventive measures described in the Pollution Prevention Management Plan include:

* Locating fuel stores and refuelling points remotely from watercourses and aquifers* Providing suitable tanks (e.g. double skinned), bunds and impermeable liners at fuel

stores and refuelling points

ELECTRONIC FILE REFERENCE: NSGP0O1-REOO-EV-PLN-00004 Page 3of 12


* Using drip trays for static plant (e.g. generators and pumps)

* Training specialist staff in refuelling and pump operations

* Providing a fire extinguisher adjacent to each item of mobile plant and equipment, and

* Making all operators aware (by induction training and toolbox talks) of the need to takecare and of their being empowered to stop and contain any spillage if seen.

1.2 Potential Scale of Incidents

The scale of incidents during construction and testing are significantly less than those duringoperation or decommissioning. In the GIC's definition of incidents, there are three tiers,affecting how any incident is reported and managed by the Client:



TIER DEFINITION (FOR GAS PIPELINE OPERATIONS)

Tier I A local spill requiring no outside intervention and can be dealt with on site on site by local staff andstockpiled equipment

Tier 2 A larger spill that would require additional outside resources and manpower

Tier 3 A large, possibly ongoing spill which will require additional regional and possibly internationalresources .... (e.g. full bore rupture, tank collapse or major tanker incident).

1.2.1 High Frequency, High Impact

Road traffic accidents are likely to be the commonest form of incident that affect Project staffand subcontractors working on the project. Any incident will be reported to the Client as soon aspracticable in accordance with the procedure. For environmental incidents, the runoff ofsediment from the Right of Way, temporary accesses and unreinstated areas is likely to be thecommonest problem requiring imediate attention, particuarly where potable or irrigation watersupplies are threatened or affected.

1.2.2 High Frequency, Limited Impact

The commonest environmental incidents are likely to involve pollution from spillages during therefuelling of mobile vehicles, plant and equipment (pumps, generators, etc.) and leakage duringtheir operation. These generally involve small volumes and are of a chronic rather than an acutenature (though potentially significant locally).

The most sensitive targets for pollution tend to be:* surface water bodies (rivers, reservoirs) and aquifers from which water is abstracted for

potable use and for irrigation* irrigation channels, and* Wetlands.

1.2.3 Moderate Frequency, Moderate Impact

Any spillage of chemicals, for eaxmple those used as additives during hydrtesting, may have asevere, local impact for a short time. The limited need for such operations and their carefulsiting and managment mean these potential impacts are managed effectively.

1.2.4 Low Frequency, High Impact

The most significant pollution incident would occur if a fuel bowser were to overturn and spillit's contents either into a watercourse upstream of an abstraction point or into an aquifer orwetland.

If a fire were to spread from a pump or generator, this would have the potential to spread outsidethe Right of Way and affect forested areas over a large area.



The effects of a landslide or severe riverbank erosion during a flood could cause a pollutionincident, though fuels and lubricants will not be sited close to watercourses. Small volumes ofpollutants are likely to be involved and dilution is likely to be at it's maximum in suchconditions.

The potential for staff to be stranded in a remote area in adverse weather could be significant inadverse weather conditions. The training of staff and use of the Journey Management Plan isdesigned to minimise these risks.

2 Emergency Response Equipment

As described in the Pollution Prevention Management Plan the equipment listed in Appendix 1for each construction site will be held on vehicles and at each:

* Site base / labour camp* Each principal crew* Each fuel bowser* Each emergency crew.

3 Incident Response

All personnel of CONTRACTOR are considered responsible for the prevention of pollution andthe provision of immediate response in the event of an incident.

CONTRACTOR's incident response procedure can be summarised as follows:

STOP the source of the spill

CONTAIN the spillage

NOTIFY the relevant bodies

3.1 Large Spillages

Immediately prevent further spillage at source.

Ensure the Emergency Crew are called to assist with clean up.

Prevent the spillage from spreading by enclosing with a bund made with sand, subsoil orabsorbent materials.

ELECTRONIC FILE REFERENCE: NSGPO01-REOO-EV-PLN-00004 Page 6of 12


Ensure that the spillage cannot enter any drains or water courses.

If the spill has entered drains if possible block the drain further down the line by stuffing withabsorbent pillows.

If the spill has entered a watercourse if possible dam or put an absorbent boom across if furtherdown stream. To dam the watercourse use sandbags, earth or a horizontal wooden plank.

UNDER NO CIRCUMSTANCES TREAT SPILLS WITH CHEMICAL AGENTS

Inform the Environmental Engineer, Community Relations Manager and Project Manager.Submit a written report. Use absorbent materials to soak up the spill. It may be necessary toexcavate contaminated spoil.

All contaminated clean-up materials and excavated materials must be disposed of as HazardousWaste.

3.2 Small Spillages

Immediately prevent further spillage at source even if only temporary e.g. drip tray or bucket.

Cover the spill with absorbent material to prevent it spreading and mop it up.Advise the Environmental Engineer of incident and action taken and submit a written report.

Dispose of the used absorbent materials as Hazardous Waste.

4. Incident Notifilcation

All CONTRACTOR staff and sub-contractors will be briefed on the importance of pollutionprevention, contingency planning and emergency response at their induction training.

All personnel involved in the project are considered responsible for the prevention of pollutionand are empowered and encouraged to take immediate and effective action hopefully to prevent,or to respond to an incident.

The first stages of response are:

STOP



CONTAIN

NOTIFY

In the event of an accident, spillage and/or pollution it is essential that the following people areinformed immediately by telephone:

* Emergency Crew* Environmental Engineer

* Community Relations Manager* CONTRACTOR'S Project Manager.

Depending on the nature and scale of the incident, the Environmental Engineer and/or ProjectManager will decide who in the Client's team to notify and what support to request. Subject to

any local agreement to the contrary, CONTRACTOR's Environmental Manager will notify andliaise with regulators and interest groups (e.g. for water abstraction), keeping the Client briefedon developments.

The CONTRACTOR's Community Relations Manager will be responsible for notifyinglandowners and local administrators and interest groups.

An Environmental Incident Notification Form is given in the Pollution Prevention ManagementPlan. A list of key contacts for each spread will be developed from that given in Appendix

After the incident has been contained and cleaned up successfully, a meeting will be held toassess

* The cause(s) of the incident* What actions and procedures worked well* What improvement are needed, and

* What actions are to be undertaken, by whom and by when.

5. Incident/Simulation Training

Periodic testing of the emergency response arrangements will be undertaken and the lessonslearned identified (as following a real incident) and improvements actioned. Training willinclude an Oil Spill Response course for key personnel.

1. INTRODUCTION

This Pollution Prevention Management Plan (PPMP) provides guidance and preventive measuresfor use within all activities associated with the construction and testing under the pipelineemergency rehabilitation programme. It will be used as a framework for the production ofindividual, site-specific Method Statements for each section of the pipeline.

In accordance with the requirements of GIC safeguard document Environmental ManagementFramework (Appendix 3, pages 40-41) the construction contractor is responsible for thedevelopment and implementation of the PPMP for construction phase.

2. IDENTIFICATION OF POTENTIAL POLLUTANTS

Potential pollutants from a project of this nature include the following (this list is notexhaustive):

* Diesel fuel, lubrication oils and hydraulic fluids, etc. from construction vehicles.* Miscellaneous chemicals (e.g. paint thinners, cement and concrete, antifreeze, biocides,

dyes, etc)* Herbicides and pesticides.* Construction wastes (packaging, welding rods, wood, etc.)* Hazardous wastes (e.g. lead acid batteries, waste epoxy coatings, contaminated soil,

photo-processing chemicals, medical wastes etc) (refer to the Waste Management Plan)* Silt suspended in runoff waters ("construction water")* Sewage (if not adequately contained and treated)* Contaminated land (pre-existing)* Noise* Air emissions (from vehicles), and* Dust.

Further potential pollutants may become apparent as the project progresses. However, the abovelist contains the majority of the major groups of pollutants.

3. POLLUTION PREVENTION

The above allows us to identify the ways by which pollution may be prevented - by stopping theSOURCE or by blocking the PATHWAY. This plan concentrates on controlling sources andpathways to prevent pollution of a receptor.

In planning the NSGPR Project has ensured that the rehabilitation avoids as many sensitivereceptors as possible. However, inevitably the rehabilitation and associated facilities passesthough or runs in close proximity to a number of receptors. At this stage of the project, it isimportant that potential sources and pathways for pollutants are identified and that measures areput in place to mitigate any potential impacts.

The following sections describe each part of the rehabilitation process, and the likely sources ofpollution, although these are not exhaustive. This can then be referred to the sections coveringpollution to land, air, water etc.



3.1 Site Establishment

Likely sources of pollution from Site Bases include:

* Bulk storage of fuels* Storage of other hazardous materials

* Sewerage facilities* Waste storage/disposal, in particular liquid wastes

* Vehicle cleaning* Noise and dust from vehicle* Water and power supplies

3.2 Transport

Applicable for all operations.

* Noise & Vibration Impacts* Traffic congestion (nuisance)* Air pollution

* Mud on roads

* Refuelling* Vehicle cleaning

3.3 Working Width Preparation & Fencing

* Silt runoff due to installation of drainage

* Disturbance to watercourses due to installation of flumes/bridges etc.* Waste generation

3.4 Topsoil Stripping

* Silt runoff to watercourses and water bodies* Exposure of contaminated land

* Damage to vegetation* Noise and dust from construction activities

3.5 Stringing, Welding & Coating

* Use of paints, coatings etc.* Waste materials* Transportation of pipe and materials* Noise of vehicles and machinery

3.6 Trench Excavation & Lowering

* Silt runoff to watercourses and water bodies* Exposure of contaminated land* Noise* Dust

3.7 Backfill & Reinstatement

* Noise and dust from construction activities* Runoff from disturbed soil



3.8 Special Crossings

* Silt runoff to watercourses due to disturbance to bed & banks* Exposure of contaminated land

3.9 Site Demobilisation

* Removal of waste* Removal of fuel storage tanks & bunds

4. PREVENTION OF POLLUTION - LAND

Pollution to land from construction projects may occur through a variety of sources. Theseinclude:

* Inadequate waste management* Spillages resulting from the storage and handling of fuels, oils and other hazardous

materials, in particular during refuelling* Pollution resulting from contaminated water

A number of measures will be implemented to prevent spillages and reduce the risk of pollutionto land.

4.1 Fuel and Oil StorageThe measures outlined below will ensure that oil storage conforms to current requirements for oilstorage.

4.1.1 The Storage and Bounding Procedure will be followed.

4.1.2 Storage tanks will not be located within 50m of any watercourse, well or dry riverbed.

4.1.3 All tanks will be either double-skinned design and / or placed in a bund of at least110% of the tank's maximum capacity. If more than one tank is stored within thebund, the system must be capable of storing 110% of the biggest container's capacityor 25% of their total capacity, whichever is greater. The bund will be impermeable(e.g. concrete-lined), without drainage points or other breaches. In the case of anyuncertainty, this clause supersedes any other requirement specified elsewhere.

4.1.4 All tank connection points will be contained within the bund.

4.1.5 All tank discharge lines will be fitted with shut-off devices that can be operated froma safe position outside the bund.

4.1.6 All tanks will be fitted with easily accessible level indicators to prevent overfilling.



4.1.7 All fuel / hydrocarbon dispensing nozzles are to be of a drip control design andsecurely locked when not in use.

4.1.8 Areas for road tanker parking and delivery shall be hard surfaced (concrete) anddrained to an interceptor. Discharge of rainwater and waste from these areas will bevia a treatment system designed to meet the water discharge standards discussed inthe Waste Management Plan.

4.1.9 At each site where diesel is delivered and stored, spillage equipment shall be installedto contain any spillage during loading.

4.1.10 Specific drainage requirements, which include oil interceptors, will be put in place atfacilities where diesel is stored and used.

4.1.11 Accumulated rainwater in bunds will be pumped out of the bund to either drains orthe ground if uncontaminated, and if contaminated, disposed of in accordance withthe GGIC Waste Management Plan.

4.1.12 All fuel storage areas will be securely fenced and locked to prevent unauthorisedaccess. Only Refuelling Operators will be allowed to dispense fuel as set out below.

4.1.13 All fuel storage areas will be equipped with an adequate supply of spill containmentmaterials (refer to Section 12 for list of spillage materials).

4.2 Refuelling

4.2.1 The Refuelling Procedure will be followed during all refuelling activities.

4.2.2 All refuelling will take place at, semi-permanent (wherever practicable) locationssuch as pipe yards and construction camps and will be from designated, bunded fuelstorage tanks rather than drums. Within the site compounds, this will be restricted tospecially constructed areas adjacent to the bunded fuel tank(s). These areas will be ofhard standing with an impermeable surface and sealed drainage system which willallow any spills to be contained or drained to an interceptor.

4.2.3 Exceptions to the above are to be made for large plant such as side booms andtrenching excavators (where removal from site to refuel is likely to be impractical orcause greater environmental impact) and for smaller fuel equipment such as chainsaws where refuelling at the workplace will be required regularly. Where refuellingon the ROW is required, this will utilise double-skinned mobile tankers.

4.2.4 Generators will be self-bunded and will have an integral fuel tank. Refuelling will beundertaken as per the procedures below.

4.2.5 Refuelling will be carried out by the nominated Refuelling Operators who will bespecifically trained in the relevant procedures. Upon arriving at the refuelling areas,the Refuelling Operators will dispense the required fuel.

4.2.6 No fuel storage or refuelling of vehicles or equipment will be allowed within 50m of



any watercourse, water body, and well, dry river bed or within any designatedwetland area or aquifer.

4.2.7 All refuelling operations on the ROW will use drip trays and/or absorbent pads tominimise spills, which will be put in place prior to the commencement of refuellingoperations. Soiled absorbents will be treated as hazardous waste and disposed of inaccordance with the GGIC Waste Management Plan.

4.2.8 Refuelling will always be carried out with the correct equipment (i.e. nozzles of theappropriate size), and only by suitably trained and experienced Refuelling Operators.

4.2.9 Basic oil spill clean-up equipment will be held at all refuelling areas (refer to Section12). In addition, drain pumps will be carried with all mobile refuelling plant and willbe available at all refuelling locations in close proximity to watercourses.

4.3 Drip Trays4.3.1 The use of integral drip trays for generators, tanks and other fixed plant will be will

be encouraged throughout the project.

4.3.2 Individual drip trays will be necessary for temporary secondary containment ofmaterials.

4.3.3 Drip trays will be checked and cleaned regularly by a designated member ofpersonnel using absorbent materials and where necessary a small electric pump. Allcontaminated liquid will be pumped to containers and taken to the nearest wastedisposal area where they will be emptied to an oil interceptor, following inspection bythe Environmental Field Officer or other nominated and trained personnel. Thiswaste will be disposed of in accordance with the GGIC Waste Management Plan.

4.4 Storage and Use of Chemicals4.4.1 All chemicals will be stored in designated, locked storage areas, taking care to ensure

segregation of potentially reactive substance (e.g. flammables should not be storedwith toxic substances). These areas will have an enclosed drainage system/bund toavoid contamination.

4.4.2 The Procurement Officer will maintain inventories of all chemicals held on-site.

4.4.3 Bunds and tanks will be constructed as per the details discussed in Section 8.1.

4.4.4 Drip trays will be provided for chemicals at point-of-use.

4.4.5 Material Safety Data Sheets (MSDS) will be provided for all substances and used inproject health and safety assessments.

4.4.6 Efforts will be made to avoid and minimise the use of hazardous chemicals duringconstruction where possible. This has been addressed as part of the wasteminimisation/treatment/disposal study contained within the Waste Management Plan.The Procurement Department will be responsible for facilitating this avoidance andminimisation.



4.5 Waste Management4.5.1 All waste will be managed in accordance with the GGIC Waste Management Plan to

ensure effective storage, handling and disposal such that no pollution occurs.

4.6 Spillage Procedures4.6.1 Procedures to handle spillages have been developed (refer to 'Emergency Procedures

in the Event of a Pollutant Spill' and 'Pollution Prevention and Control - Land'Procedure

4.6.2 These contain details on the use of spill kits, including absorbents, to contain aspillage, followed by clearing up and disposal of the spillage and spillage material.

5. PREVENTION OF POLLUTION - WATER

Water pollution may result from a variety of sources, including the following:

* Spillages of fuel, oil or other hazardous substance, especially during refuelling* Silt runoff from the right of way* Pumping of silt water from excavations* Disturbance of watercourse banks and bed during watercourse crossings* Washing of vehicles or equipment* Exposure of contaminated land and groundwater

Spillages etc may travel quickly downhill through gullies etc to a watercourse or water body.Once in a watercourse, it can be difficult to contain the pollution which can then impact over awide area downstream. It is therefore vital that prompt action is taken in the event of anypotential water pollution incident.

5.1 FuelUOitUChemical Storage

5.1.1 The storage of potentially polluting materials, refuelling and maintenance of mobileplant within 50m of all watercourses/water bodies, dry riverbeds and withindesignated wetlands and aquifers will be prohibited.

5.2 Suspended Solids

5.2.1 Erosion control measures will be installed in accordance with and are detailed in theReinstatement Management Plan.

5.2.2 To control suspended solids the Surplus Water Management and Silt ControlProcedure will be followed.

5.2.3 Once the working width has been stripped of topsoil, the subsoil becomes exposed.During wet weather this may result in uncontrolled release of suspended solids fromthe work area. Contractor will plan all access routes, excavations, topsoil and subsoilstorage so as to reduce to a minimum any run-off. This will be described in the GGICReinstatement Management Plan.



5.2.4 No trench likely to act as a connection to a watercourse will remain open beyond theduration necessary for installation of that section. Trench breakers will be installed toprevent sedimentation run-off.

5.2.5 Where any area of the spread is at risk from silt pollution washing off into awatercourse of water body, effective measures will be put in place to ensure that suchpollution does not occur. Such measures may include:

* Use of silt fences* Use of straw bales and Terrani to deflect and filter water* Use of a system of bunds and grips to prevent water from entering watercourses, etc.* Use of holding/settling lagoons to store water running off the spread. It is intended to

use natural settling rather than flocculants to facilitate sedimentation following whichclean water can be disposed.

5.3 Watercourse Crossings

5.3.1 Watercourse crossings will be undertaken in accordance with and are detailed in theReinstatement Management Plan.

5.3.2 A number of techniques will be used to undertake river crossings. MethodStatements should be produced to cover each crossing and will include pollutionprevention measures and erosion protection, to ensure that sediment does not enterthe watercourse, during construction, in periods of inactivity between installation ofthe two pipelines and during operation.

5.3.3 For each Method Statement, the following principles will be observed:* River flow will be maintained at all times through fluming or damming / over-

pumping.* No refuelling or fuel storage will be allowed within 50m of watercourses.* Where required, bunds, grips and other measures will be implemented adjacent to

watercourses to prevent silt ingress from the construction spread.* Wherever possible, work in stream channels will be carried out without the use of 'in-

river' techniques, instead using techniques that divert the flow around the worksthrough flumes or by damming and pumping. This will minimise sediment release.

* Where required, water will be filtered through straw and Terrain to reduce sedimentloading.

* The design of each watercourse crossing will assess, and where necessary mitigate,any additional risk of leakage or other pollution.

* Full reinstatement will be undertaken immediately upon completion of backfilling.

5.3.4 Machinery will not operate in a watercourse without the prior notification of theEnvironmental Manager and without having a method statement approved by GGICin place.

5.3.5 Wet cement and/or concrete will not be allowed to enter any watercourse, pond orditch.

5.3.6 During site establishment, where watercourses will cross the construction site(regardless of whether they are crossed by the pipeline itself) it may be necessary in

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00003 Page 10Of 21


order to minimise pollution to:* Temporarily divert watercourses around the working area (i.e. over-pump).* Temporarily culvert the watercourse through the working area (i.e. flume through).

5.3.7 Where site traffic has to cross watercourses, temporary bridges or culverts / flumeswith retaining boards will be installed.

5.3.8 Sedimentation problems relating to fish populations within watercourses will besignificantly reduced by ensuring that:

* Wherever possible, excavations within watercourses take place after the eggs presentin spawning areas have hatched; and

* Excavations are only undertaken after the most sensitive early stages of the recentlyhatched fishes' lives have passed.

5.3.9 Excavation within watercourses will therefore be confined where practicable to theperiod between August - January.

5.4 Pumping Operations

5.4.1 There will be no discharges to watercourses or water bodies of any form without priorconsent of the Environmental Manager or Environmental Field Officer.

5.4.2 A Permit to Pump procedure will be instigated for all works. A Permit will only beissued to trained personnel once pollution control measures are in place and once thedischarge has been approved by the Environmental Field Officer.

5.4.3 Surface or groundwater from excavations will not be pumped or allowed to draindirectly into watercourses, field drains etc without adequate filtration or settlement.Construction water will be disposed of in accordance with the Waste ManagementPlan. Water discharges, for example from excavations, will be made to land.

5.4.4 Pumps used during the works, including those employed during river crossings willbe sited at the maximum practicable distance from watercourses.

5.5 Cleaning and Washing5.5.1 No tools and/or equipment will be cleaned on the ROW. Should be provided special

washing area where can be washed contractor transport and equipment. The washingarea should have special mud trap.

5.5.2 Shovels and brushes will be used at all active road crossings to allow cleaning ofvehicles to prevent excessive mud being carried onto public roads.

5.5.3 Collected mud should be disposed in accordance with the Waste Management Plan.

5.6 Site Drainage5.6.1 Site drainage will follow the Drainage Works Procedure.

5.6.2 Cut off drains will be installed where necessary to intercept surface water, to preventit from entering the work area.



5.6.3 Diesel-loading areas for road tankers will be impervious, kerbed and will drain freelyto a suitable oil interceptor (as described below).

5.6.4 Oil interceptors will be installed in the drainage systems of facilities as follows:* Where no diesel storage is undertaken, an interceptor will not be installed;* Where diesel storage is undertaken, but an interceptor has not been included in the,

Contractor will install an interceptor, which will be connected to a suitable soak awayfor final discharge.

* Where diesel storage is undertaken and an interceptor should be installed. Contractorwill ensure that an interceptor is installed.

5.6.5 The interceptors discussed above will be class I type interceptors sufficient incapacity to cope with:

* A diesel spill of up to 7.6 mi3 ; and* A maximum rainfall on the kerbed diesel-loading area of up to 50 mm/h;

6. POLLUTION PREVENTION - AIR

The principal sources of air emissions are likely to be exhaust fumes from vehicles and plant,dust from the quarrying of soil and rock and from vehicle movements and fumes from solventsin paints and coatings and/or from storage and use of fuels.

6.1 Vehicles

6.1.1 All new vehicles will comply with all relevant EU directives for emission standards

6.1.2 Vehicles/equipment purchased 'as new' after contract award shall comply withEuropean Community emission standards in force on the purchase date. Vehicles/equipment not purchased 'as new' after contract award shall be maintained so thatnoise and emissions levels are no greater than when the vehicle/equipment was new.

6.1.3 Contractor will maintain a register of all vehicles and machinery on site that willinclude records of inspections.

6.1.4 Vehicle refuelling will be undertaken so as to avoid fugitive emissions of volatileorganic compounds through the use of fuel nozzles and pumps and enclosed tanks (noopen containers will be used to stored fuel).

6.2 Dust Generation6.2.1 A 30kph (20mph) speed limit will apply to all unmade roads. Further reductions to

16kph (1Omph) may be used locally where there are particular problems with dustemissions.

6.2.2 If deemed necessary in dry conditions or where significant quantities of dust arebeing or are likely to be produced mitigation measures will be arranged with theConstruction Manager. Mitigation measures will include:



* Damping down using water bowsers with spray bars;* Sheeting of construction materials and storage piles; and* Use of defined haulage routes and reductions in vehicle speed where required.Such measures will be used, in particular, where human or animal receptors lie within300m of the ROW.

6.3 Fires6.3.1 Burning of waste on any construction site is forbidden.

6.4 Ozone Depleting Substances6.4.1 Contractor will not use ozone depleting substances (ODS) or products with known

global warming potential (GWP).

7. POLLUTION PREVENTION - NOISE & VIBRATION

Construction activities are likely to produce a variety of noise sources of different types rangingfrom those of a short duration and low intensity to those of high intensity or longer duration.The Noise Procedure will apply.

Receptors include all dwellings, places of work and areas used for leisure activities as well aswildlife sites and livestock. The extent of the impact of noise depends both upon the nature ofthe source and upon the pathways between source and receptor. The level of noise that reachesthe receptor depends upon the attenuation factors that exist along the noise pathway. Theprincipal attenuation factors are distance, barriers and surface type.

Noise is of greatest impact at night. For this reason, Contractor activities will be undertakenduring daylight hours.

7.1 Noise & Vibration Warnings7.1.1 Warnings will be given of impending works to all potential receptors within a lkm

radius of the right of way through collaboration with the Construction Team and theEnvironmental and Community Liaison Teams through public notices and local newsin collaboration with the Community Liaison Team.

7.1.2 Close liaison with the occupants of properties within noise sensitive locations will bemaintained by GGIC, in order to ensure that they are aware of the timing and durationof activities.

7.1.3 Induction training and tool-box talks will include a discussion of noise prevention onsite.

8. POLLUTION CONTROL EQUIPMENT

In the event that the control measures discussed throughout this PPMP fail and material such asoil, fuel and chemicals escape to the environment, through spillage or leakage, spill kits are



required to enable the swift control of the escape to minimise and prevent any environmentalimpact.

8.1 Spill Kits

8.1.1 All fuel storage and refuelling areas should be supplied of spill containmentmaterials. A spill kit will also be carried on diesel trucks. Spill kits will containabsorbent pads, booms, plastic bags, ties, shovels, saw dust (at least 3 bags), rubbergloves.

8.1.2 The following sections state what spill equipment will be supplied.

8.2 Construction Contractor Main Crews8.2.1 Each main crew will carry:

* Absorbent granules x 2 bags* Heavy duty plastic bags x 5* Absorbent pads x 500* Straw Bales x 20* Terram x I roll* Shovel x 3* Saw dust x 5 bags

8.3 Environmental Emergency and Emergency Crew8.3.1 Each mobile emergency crew will carry:

* Absorbent granules x 4 bags* Heavy duty plastic bags x 10* Spade x 2* Absorbent pads x 100* Shovel x 3* Saw dust x IO bags

9. EMERGENCY RESPONSE

All spills should be treated with a matter of urgency and as such constitute an'emergency/spillage response'. Consequently both the Emergency Response Plan and thespillage procedures (which will be maintained both on-site and in the emergency bag) within thisPPMP should be consulted to determine the correct response to the spillage, includingcommunication routes and containment/clean-up respectively.

The equipment detailed in Section 12 is intended for use at construction facilities and sites wherethe potential for small spills is high. In the event that the worst case scenario occurs, whichincludes a fuel bowser or a vehicle tanker overturning, GGIC would initiate the EmergencyResponse Plan for Contractor which includes communication with GGIC and the use ofemergency spill response equipment.



10. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL -LAND

Pollution prevention is dependent on the strict adherence to the procedures described in thePollution Prevention Management Plan. The most likely pollutants on site are diesel, oil,hydraulic fluid, cement and a limited range of job specific chemicals. The potential for smallspills and leaks is high on a construction site. To limit their environmental impact the followingprecautions will be in place:

* Drip trays will be installed under pumps and other high risk equipment to preventspillages of fuel or oils. Drip trays will be checked daily; collected rain water willonly be tipped out after any oil is taken off the water surface with spill kitmaterial.

* There will be sufficient clean up material on site to cope with all foreseeable smalland medium size spills.

* Under no circumstance treat spills with chemical agents.* The Environmental Emergency Crew will be called for assistance if required.* All site vehicles should carry a Spill Kit.* Extra spill kits and bags of granules will be stored at areas of high risk, such as

refuelling points and water courses.* Refuelling will be carried out by designated persons only.* Fuel Bowsers will carry extra spill kit material and granules.* Refuelling will not take place within 50m of a watercourse, or near top soil

storage piles.All Foremen will hold a copy of the Emergency Procedure and EnvironmentalField Manual on site.

11. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL -AIR

Emissions that can pollute the air can be exhaust fumes from machinery, fumes from chemicals,coatings and solvents or mechanical processes, dust and grit generated by site operations. Thefollowing procedures will be put in place to reduce the impact of such emissions:

* All vehicles used on the project will be in good operative condition. Exhaustemissions from vehicles will be reduced as much as possible.

* Generators will be switched off when not in use.* Fuel stores will be closed to ensure that there are no fugitive emissions of Volatile

Organic Compounds.



* Gas/air monitors will be used to check air quality. Proper training and appropriatebreathing apparatus will be provided, along with emergency procedures forconfined space working.

* During the commissioning period of the pipeline and associated works, somedischarges will be made to the atmosphere. These local discharges will bymonitored by the GGIC to avoid any damage or deterioration to the environment.

* During prolonged periods of dry weather, dust may cause a nuisance to localresidents and damage nearby crops, vegetation and animal habitats. For majordust control on the working width, a water sprinkling system will be used asnecessary. Adequate P.P.E. will be provided for personnel working in theseenvironments.

* A 30 k.p.h. speed limit will operate on unmade roads and further reductions maybe used locally to reduce excessive airborne dust during dry spells.

* Haul lorries carrying dusty loads will be covered.* Burning on site is forbidden.

12. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL- WATER

The most likely pollutants on site are diesel, oil, hydraulic fluid, cement and a limited range ofjob specific chemicals. Procedures dealing with the potential for silt pollution are dealt with in EP204. Pollution prevention and control is dependent on the strict adherence to the followingprocedures:

* Storage tanks will not be located near any watercourse or peaty soil.* Refuelling will take place at least 50 metres from a watercourse. During any

activity concerned with the crossing an absorbent boom will be installeddownstream of the crossing point prior to commencement of the work.

* Washing of vehicles will not take place in a watercourse.* Vehicle washing facilities will be designed to drain into the special mud trap.* Wet concrete and cement will not be placed near a watercourse.

13. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL- EXCESS WATER MANAGEMENT AND SILT CONTROL

Pollution from suspended solids is most likely to occur from pumping out excess water from thetrench, which has accumulated from seepage or rainfall, or from uncontrolled run-off from thework site into the watercourse. It is preventable if the following guidelines are rigidly adhered to:

* The first message is 'Take 5 minutes to think about what you are going to do.Does it comply with the guidelines?'

* When there are steep slopes either side of a watercourse a slit trench, filled withstraw, like a deep litter, will be excavated parallel and close to each watercourse at



the time of installing the running track and flume pipes. This is a quick, cheap andeffective way of preventing run off from the spread due to rainfall.

* Filter fences will be installed, draining at an angle, but trapping silt. These will bemaintained at regular intervals.

* The running track will be humped and 'lipped' as it crosses a watercourse toprevent run off in adverse weather conditions.

* Straw bales will be stored at all watercourses.* Straw bales will be replaced when they have become sodden and silt laden.* A permit to pump system will be instituted and regularly inspected by the

Environment Manager.* All pumps, or series of pumps in a confined location, will have a designated

attendant responsible for ensuring the pump is in good working condition and iscomplete with drip trays. He will check that the appropriate consents to dischargewater are in place before operating the pumps.

* No water will ever be pumped directly into a watercourse.* All major watercourses will have a sign stating 'pumping without a permit and

directly into a watercourse is prohibited'.* All pumps will be labelled with a list of operating procedures.* All pumps will be checked to make sure they are in good working order before

coming on site.* Pump hoses will not be placed directly on the floor of the trench where they can

suck silt.* A stone filled sump, dug on the bottom of the trench, will be used as an initial

filter.* Water will be pumped at low volume and filtered through straw bales. A

settlement tank and straw bales will be used if the quantity of water justifies this.A settlement tank is not effective if the rate of flow is too fast to enable suspendedsolids to settle.

* Care will be taken to avoid soil erosion of river and stream banks.* Temporary holding lagoons will be excavated if necessary.* The most effective way to clean water is to filter it through dense vegetation.

However, this is dependant on a suitable field adjacent to the works andagreement from the landowner.

14. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL- STORAGE AND BUNDING

The avoidance of environmental damage, as a result of the inadequate storage or misuse of anysubstance hazardous to health, will be ensured through strict adherence to the company MSDSprocedures and the principles identified in specific risk assessments.

General* The main substances to be used on Site that will fall under MSDS will be diesel,

paraffin, lubricating oils, Epoxy paints.* No potentially polluting materials or substances will be stored within 50m of any

watercourse, well, dry river bed or peat land, or in such a situation that these can



fall or be carried into a watercourse. Any inadvertent drainage from the storage ofsuch materials will not be allowed to enter a watercourse.

* Hazardous installations will be checked daily.Fuel Storage

* Diesel fuel will be stored in large purpose built tanks meeting projectspecifications (either double-skinned and/or bunded) in a designated area of theconstruction facilities and sites. All tanks, gauges and pipe work will beconstructed in accordance with the appropriate standard.

* All tank discharge lines will be fitted with shut-off devices that can be operatedfrom a safe position outside the bund.

* All tanks will be fitted with easily accessible level indicators to preventoverfilling.

* All fuel / hydrocarbon dispensing nozzles are to be of a drip control design andsecurely locked when not in use.

* The concrete fuel bund will conform to WB Guidelines, being at least 110%aggregate volume everything stored in the bund, and impermeable. All hoses willbe stored inside the bund.

* Oil and lubricants will be stored within the confines of the bund.

* Locks are fitted to all fuel storage tanks. There is a nominated person to overseerefuelling and delivery and to ensure there is no spillage.

* Areas for road tanker parking and delivery shall be hard surfaced (concrete) anddrained to an interceptor. At each site where diesel is delivered and stored,spillage equipment shall be installed to contain any spillage during loading.

* Refuelling will follow the Refuelling Procedure

* All fuel storage areas will be securely fenced and locked to prevent unauthorisedaccess. Only Refuelling Operators will be allowed to dispense fuel.

Fuel storage areas will be provided with suitable hazard signage in accordancewith WB Best Practice.

* In areas of potential risk, emergency procedures will be prepared and pollutioncontrol equipment provided, such as Spill Kits and absorbent granules. These willalso be carried by all the Contractor's vehicles on the site and by refuelling



bowsers. Absorbent booms are part of the Spill Kit. A supply of straw bales willalso be stored by every watercourse.

* Drip trays will be placed under all pumps, checked daily and emptied inaccordance with the Waste Management Procedures. All vehicle maintenance andfitting work will be done with an attendant drip tray.

Other Chemicals

* All chemicals will be stored in designated, locked storage areas, taking care toensure segregation of potentially reactive substance (e.g. flammables should notbe stored with toxic substances). These areas will have an enclosed drainagesystem/bund to avoid contamination.

* Only specifically trained (certificated) personnel will use and handleherbicides/pesticides when and if they are required on this project. Certificateswill be checked by GGIC's Safety Manager. Method Statements and RiskAssessments will be produced and approved to control the use ofherbicides/pesticides. Herbicides will not be used in windy weather or nearwatercourses

15. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL - NOISE

Noise levels can be predicted from knowledge of the type and number of plant to be used forvarious activities. The activities listed will not necessarily occur continuously or simultaneouslybut in stages with peaks of activity separated by periods of relative inactivity. The followingprocedures will be put in place:

* Liaison will take place with the local community and residents will be notified.Special attention will be paid to sensitive locations, eg schools, hospitals etc.

* A systematic noise monitoring programme will be implemented at all sensitivelocations.

* All will have effective silencers fitted and kept in good condition. Full protectiveequipment, particularly ear defenders and/or plugs will be provided on site andavailable to all operatives.

* Noise pollution measures such as controlled venting, silenced equipment, preferredtime of day and screening will be used.

* Construction activity will normally be confined to daylight hours Monday toSaturday. As the requirement for Sunday or night working cannot be ruled out,discussions will take place with the local authority before such operation begins.

* Trench less crossings of roads and railways can also be a source of noise.



* Ecologically and Residential Sensitive areas, or areas within 150m of the pipelinewill be monitored and if the level of construction noise increases added screening andpreferred working hours will be implemented.

* There will be minimal plant movement in sensitive areas.

16. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL- DRAINAGE WORKS

Drainage requirements will be established for each landowner/occupier during Pre-Entry negotiations.These requirements (Drain types, locations, depths) will be indicated on a strip map.

Pre-Construction drainage will be installed prior to top soil removal.

Header drains will be installed to collect the drain water from the top side of the spread

Trenches for drains will be excavated by either tracked excavator, wheeled excavator or by specialisedtrenching machine, depending on ground conditions. The trench bottom will be even -and clean.

Drains (jointed) will be tied in and incorporate either a purpose made branch.

Drains will not be used to drain silty run-off from the spread.

Drains will not be used to discharge pumped trench water into.

Care will be taken if trench water is being pumped into a field, that it is not finding its way directlyinto a field drain, and straight out to a sensitive watercourse.

Top soil reinstatement will take place immediately behind Post Construction drainage works.

Header drains should be 3xsize to take surface water run off into account.

17. ENVIRONMENTAL PROCEDURE POLLUTION PREVENTION ANDCONTROL - REFUELLING

Refuelling is a high risk activity and the potential for spills and leaks is high. Pollution prevention isdependent on the strict adherence to the following procedures:

* Where possible refuelling will take place at, semi-permanent locations with ahard-standing, bounded fuel storage tanks rather than drums. These areas willhave a sealed drainage system that will allow any spills to be contained or drainedto an interceptor.

* Site Plant such as side booms and trenching excavators and smaller fuelequipment such as chain saws will be refuelled on the ROW. Double-skinnedmobile bowsers and/or tankers will be used.

* Refuelling personnel will be subject to specific training on the importance ofrefuelling techniques, response to a spill and use of the Emergency Procedure.

* Two people will refuel any equipment - at the discharge and receptor points.* Spill Kits and absorbent granules will be carried at all times.* Electric hand pumps will be carried at all times.

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00003 Page 20Of 21


* Instructions for equipment use will be in Georgian and English.

* No smoking will take place within 50m of the refuelling exercise* The equipment and fuel bowser will be parked for preference in a designated area

that is level and at a safe distance - >50m - from drains and watercourses(including dry watercourses).

* Refuelling line should be kept as short as possible.* Drip tray is to be placed under discharge nozzle.

* Cease pumping before any fuel overflow.* The refuelling process will be attended at all times and no delivery valves will be

jammed open.* Delivery hoses will be turned off and locked when not in use.* Hoses and valves will undergo regular, and recorded, maintenance checks.* All leaks and spills will follow the clean up and reporting procedure.

1. INTRODUCTION

This document is GIC framework Cultural Heritage Management Plan (CHMP) for the GasPipeline emergency rehabilitation programme. This CHMP focuses on the construction phase ofthe project and forms part of GIC's Environmental and Social Management System (ESMS).

In accordance with the requirements of GIC safeguard document Environmental ManagementFramework (Appendix 3, pages 40-41) the construction contractor is responsible for thedevelopment and implementation of the CHMP for construction phase, based upon theframework provided here in this document.

The following are the objectives of the Cultural Heritage Management Plan:

* Conservation during the lifetime of the project, protection of sites in the vicinity ofconstruction activities wherever required, provision of access tracks where appropriate

* During Construction, undertake archaeological digs* In order to address these objectives the Cultural Heritage Management Plan will address

as a minimum the following:* Training for MCG Contractor staff* Protection of sites in the vicinity of construction activities by demarcation fences* Protect of sites through ensuring access tracks to new or existing facilities are carefully

sited* Respect the cultural heritage of the areas in which work is carried out* Mechanism for agreeing stopping work when encountering a potential archaeological site

during ROW clearance or excavation activities

2. ARCHAEOLOGICAL AND MONUMENTS MITIGATION MEASURES

CONTRACTOR will develop an Archaeology Procedure and will as a minimum comply withthe requirements defined therein.

During the Pre-construction Survey any archaeological and monument (castles, churches,buildings etc) sites will be clearly demarcated in liaison with GIC. Should marking posts andfencing be stolen GPS and KP points will be used to locate the site in question. GIC will providearchaeologists to keep a 'watching brief' as follows:

* An archaeologist will be present with each ROW clearing team; and* An archaeologist will be present with each trenching team.

CONTRACTOR are aware that the intention will be to complete all digs during the constructionphase but that it might be necessary to defer some investigations. CONTRACTOR will co-operate with the archaeologists.

If, during construction activities, CONTRACTOR personnel think they have encountered anarchaeological site the following will be undertaken:

* Work will stop immediately in that vicinity;



* The site supervisor and the GIC representative will be informed;* The site supervisor will then request the archaeologist to investigate the find;* Normal installation activities will only resume following clearance by the GIC

representative.

CONTRACTOR will also assist GIC in adoption of the following measures developed to reducethe impacts on archaeological areas and monuments during construction:

* Temporarily avoid clearing sections of the ROW or trenching whilst investigations areunder-way or a re-route is negotiated if requested by GIC;

* The use of protective measures on the running track;

* The use of specified mechanical plant, e.g. chain trenchers;* Restrictions on the use of ripping techniques;* The use of certain re-instatement techniques indicated on appropriate route maps;* Provide demarcation fences wherever necessary in order to protect adjacent sites; and* Account shall also be taken of cultural heritage in the location of new facilities or

improving existing ones, e.g. access tracks

In addition, it is noted that there are known to be cemeteries in close proximity to some sectionsof the pipeline. CONTRACTOR will ensure that there is no disturbance to these sites byensuring that construction activities are confined to the working area.

3. ENVIRONMENTAL PROCEDURES - ARCHAEOLOGY

These procedures apply to any work involving top soil movement or trench excavationthroughout this project. Where possible all archaeological sites will be avoided by constructionactivity.

3.1 Purpose

CONTRACTOR shall be committed to complying with Georgian Law, the GIC CulturalHeritage Plan and the provisions in the Environmental and Social Impact Assessment mitigatingdamage or disturbance to archaeological sites and standing monuments.

This procedure describes the measures necessary to avoid disturbing the archaeological andmonument heritage in the first instance, or if this is impossible, to prevent its unrecordeddestruction.

Georgia is particularly rich in archaeological remains. Palaeolithic (before last the Ice Age) lithicassemblages have been identified; Neolithic settlements; Bronze Age burial structures; Classicalremains; Mediaeval villages are all present in the record. Georgia has always presented a routethrough the Caucasus for migrations and invasions, so the potential for undiscovered sites ishigh.

GIC will employ archaeologists to survey prior to, and during the construction work, and to keepa watching brief during topsoil removal. This brief is undertaken to detect any unknown



archaeological remains. Co-operation between the construction team and the archaeologists is ofparamount importance.

The process of top soil stripping will reveal any archaeological site or find. Random, unstratifiedfinds have limited informational return as they are not in any meaningful context. What is ofvalue are stratified, in-situ finds that are in context and can therefore be dated. For this reason itis important for machine operators to be aware of the different soil types as they are beingexcavated. Archaeological sites may well have lost stones and wood that delineates structures,but organically enriched soils and hearths will remain and be noticeable. It is also necessary forwork to stop immediately to enable the maximum opportunity to record the precise context of afind.

3.2 Responsibilities

The Construction Manager is responsible for carrying out the work in accordance with thisprocedure and ensuring top soil is not stripped without archaeological supervision.

The Environmental Manager is responsible for co-ordinating the archaeologist and the relevantconstruction crews.

The GIC Archaeologist is responsible for carrying out the watching brief and writing a dailyreports.

The GIC Archaeologist has an ongoing dialogue with the Centre for Archaeological Studies.

The CONTRACTOR is responsible for formally notifying the Georgian Centre forarchaeological Studies of archaeological finds. The Client calls in the excavating team to fullyexplore archaeological material. The Construction Manager is responsible for carrying out anycorrective action during the project. All personnel are responsible for reporting archaeologicalfinds or human remains to the Project Archaeologist or Environmental Manager.

3.3 Procedure

During construction:

* An archaeologist will be present with a watching brief during all top soil stripping, soilmovement and trenching activity.

* An experienced and careful machine driver will operate in areas with a high potential forarchaeological finds. Their skill is essential.

* The workforce will stop work should the archaeologist require time to investigate.* No archaeological material will be removed from a site without written permission.* All human remains discovered will be reported to immediately.

In the event of discovering archaeological material:

* The Project Archaeologist will identify the location with a flag and carry out preliminaryinvestigation.



* If the area is of little consequence, or can be speedily excavated during investigation, itwill be dealt with and recorded in the daily report.

* If the area is of greater archaeological significance, or requires more detailed and timeconsuming excavation, the Archaeologist will report to GIC's Environmental Manager,who will immediately alert the Client.

* The Client will arrange a site visit with the Centre of Archaeological Studies andorganise the timing of excavation requirements.

1. INTRODUCTION

The approach that CONTRACTOR will take to successfully reinstate those areas disturbed byconstruction activities are discussed in the Reinstatement Management Plan (RMP). The importance ofacknowledging the significance of location, timing and condition (both pre-construction and post-construction) with regard to reinstatement is paramount.

In accordance with the requirements of GIC safeguard document Environmental ManagementFramework (Appendix 3, pages 40-41) the construction contractor is responsible for thedevelopment and implementation of the RMP for construction phase, based upon the frameworkprovided here in this document.

The approach that CONTRACTOR will take to successfully reinstate those areas disturbed byconstruction activities are discussed in the Plan. The importance of acknowledging the significance oflocation, timing and condition (both pre-construction and post-construction) with regard to reinstatementis paramount.

1.1 Reinstatement Locations

The project areas considered in this Management Plan are as follows:

* Pipeline ROW - where the initial extent of reinstatement will be location dependant as outlinedbelow;

* Temporary access routes - will be fully reinstated in environmentally sensitive areas. The optionwill be given to local communities to leave project temporary access roads in place where theyare located outside environmentally sensitive areas;

* Temporary facilities including construction camps and pipe yard sites - will be fully reinstatedupon removal of the temporary facility; and

1.2 Third Party Property, Land and Crossings

The specific reinstatement measures required on private land will be agreed with the landowner prior toconstruction work commencing on the site in accordance with the Land Entry Procedure; the details willvary on a case-by-case basis. As a minimum it is expected that the land will be retumed to its pre-projectcondition.

The original condition of a specific site (KP) will be considered to be that of the Pre-construction Surveyrecords and photographs. Photographs will be taken of the site prior to construction activities takingplace and the boundaries and other features of the land will be marked and GPS locations recorded toassist in reinstatement.

1.3 Environmentally Sensitive Areas

By definition environmentally sensitive areas require a higher standard of final reinstatement and havebeen identified as areas in which the construction of the pipeline will have a potentially significant visualand/or ecological impact.

1.4 Watercourses

Reinstatement of all watercourses will be undertaken immediately upon completion of backfilling.

1.5 Land other than ROWLand other than the ROW includes the following:



* Land at construction support facilities;* Waste disposal sites; and* Existing roads and access.

1.6 Reinstatement Timing

Reinstatement can be broken down into three distinct stages as outlined below:

1) Pre-installation/construction of pipeline and facilities

* Pre-construction survey;* Clearing and grubbing of project areas;* Removal of waste in accordance with Waste Management Plan;* Stripping of topsoil to site specific line and level; and* Excavation of subsoil to site specific line and level.

2) During installation/construction of pipeline and facilities

* Management of soils to minimize loss and contamination;* Construction of erosion control measures;* Maintenance and inspection of erosion control measures; and* Collection and storage of waste materials in accordance with Waste Management Plan.

3) Post-installation/construction of pipeline and facilities

* Demolition of temporary access roads and facilities;* Reinstatement of excavated subsoil;* Removal of plant and equipment from site not needed for topsoil reinstatement;* Reinstatement of topsoil;* Removal of waste materials in accordance with Waste Management Plan;* Maintenance and inspection of erosion control measures;* Removal of plant and equipment from site not needed for bio-restoration;* Bio-restoration of project areas;* Removal of plant and equipment; and* Maintenance of ROW and project facilities.

1.7 Reinstatement Condition

In addition, to the reinstatement locations discussed above reinstatement will be conducted to suitableconditions dependant upon the location. The level of reinstatement to be implemented at specificlocations is related to the location classification, where the following categories apply:

* A - Environmentally Sensitive Areas;* B - Special Agricultural Areas; and* C - Standard Areas.

These categories will be further defined for each specific project area

As a minimum, all areas will be reinstated to their original condition, or better, to the satisfaction of theowner or authority, notwithstanding approval from GGIC. All pre-entry agreements are to be signed-offby CONTRACTOR and the owner or authority, in the presence of GGIC representatives, prior to



demobilisation from site. Photographs of the condition of the area prior to and after reinstatement will beused for reference.

2. PRE-CONSTRUCTION SURVEY

The scope of the Pre-construction Survey is the total land take of the emergency rehabilitation sections,prior to. during and after construction of the project. This includes the following:

* ROW;* Existing and proposed access routes;

* Camp and pipeyard sites; and

3. CLEARING PROJECT AREAS

Tree and vegetation clearance will be undertaken in accordance with the Tree-felling Method Statement.To reduce the impact on the landscape, however, sensitive clearance will be undertaken where possible.

CONTRACTOR has to subcontract felling and cutting to a specialist forestry organisation.

3.1 Pipeline and Temporary Facilities

During the Pre-construction Survey particular attention will be given to mitigating landscape impacts atthese locations. In forested areas the retention of some large trees on the ROW and the irregular plantingof trees and shrubs as close to the middle zone of the corridor as possible (whilst complying with theplanting regulations) will help to break up the visual impact of the ROW.

Ecologists employed by GGIC will accompany clearance crews along some or all of the ROW.CONTRACTOR understand that the ecologist will undertake the following:

* Monitor that routing constraints are adhered to and participate in any decision to Modify the routebecause of non-environmental requirements;

* Undertake any final conservation work that appears to be necessary and which may lead to GGICinstructing CONTRACTOR to 'skip' a section;

* Work in co-operation with the archaeologist

Felling activities will take the following into consideration:

* Where the ROW encroaches on forest areas, rather than cutting straight across a forest edge, anirregular curved edge will be created;

* To avoid increased tree felling, where possible, the ROW width will be reduced to accommodatethe creation of curved and irregular edges;

* Removal of individuals of protected species including rare (Red Data Book) species, as far aspracticable, will be minimised and avoided through consultation with the site environmentalists.

* Individuals to be conserved during ROW clearance, will be identified during the Pre-constructionSurvey and marked with a different colour tape to denote them from trees marked to be felled;and

* No felling of trees or cutting of vegetation shall be permitted other than strictly necessary withinthe ROW and at other construction facilities.



Felled trees and cut branches will be removed to a compound and put under the control of the localauthority. Foliage and small trees will be provided to the local community for firewood in accordancewith the Waste Management Plan. Any excess material will be windrowed or shredded to producehorticultural mulch.

3.2 Faunal Mitigation Measures

CONTRACTOR will assist GGIC in adoption of the following measures developed to reduce the impactson animals during construction:

* Temporarily avoid clearing sections of the ROW or trenching whilst investigations are under-wayor a re-route is negotiated if requested by GGIC;

* All field construction staff will be made aware of the location of endangered mammals;* Peaks of animal activity and sensitivities in construction planning will be taken into account; The

length of open trench will be minimised;* No feeding of wildlife will be allowed;* No deliberate disturbance to wildlife will be tolerated;* All litter and other wastes will be removed from working areas, particularly in forest areas, in

accordance with the Waste Management Plan;* No dogs will be allowed on working areas;* Access across the working area will be maintained for wild animal movement;* Migration corridors between working areas will be preserved;* Construction activities restricted in certain areas to avoid impact on the migration pattems of

endangered species; and* Provide demarcation fences wherever necessary in order to protect adjacent sites.

4. TOPSOIL REMOVAL AND STORAGE

CONTRACTOR's approach to topsoil removal and storage to facilitate appropriate reinstatement of thepipeline and facilities is outlined within this section. Detailed procedures for topsoil removal and storageare covered in the Construction Method Statement for Topsoil Stripping which addresses the engineeringsolutions and should be read in conjunction with this Management Plan.

It is understood that the success of reinstatement is dependent upon the ability of CONTRACTOR tosuccessfully manage topsoil throughout construction. Protection of the topsoil will be ensured through itsseparation from subsoil, and storage in a manner that retains its structure and seed bank whilst minimizingthe potential for topsoil loss.

4.1 Topsoil Stripping

CONTRACTOR will develop procedures to address specific requirements with respect to topsoilstripping which include, but are not limited to, the following:

* Depth of strip as determined by site specific ground conditions* Width of strip across ROW* Careful handling.

The topsoil will not be handled by CONTRACTOR when the following conditions are observed:



* The topsoil is frozen;* The site is experiencing persistent rainfall;* The topsoil is saturated; or* Handling will damage the structure of the topsoil.

4.2 Topsoil Storage

The storage of topsoil in stockpiles, no more than 2m high with side slopes at a maximum angle of 450,will take into consideration the following:

* Drainage of the stockpiles, including the provision of gaps at low points, to prevent underminingand wash-out;

* Prevention of stockpile surface erosion through surface compaction (through the application ofdownward pressure to the stockpile with an excavator bucket) but not to the extent that anaerobicconditions occur;

* Minimization of topsoil loss (refer to section 6.5 for erosion control);* Providing vehicular access through the stockpiles;* Dedicated storage locations that prevent the stockpiles being compacted by vehicle movements or

contaminated by other materials; and* Segregation from subsoil stockpiles.

In the event that the topsoil stockpiles experience erosion CONTRACTOR will install erosion mattingover the stockpiles as a corrective action if further surface compaction and seeding fails. CONTRACTORwill protect the stockpiles from flooding by placing berms around the outside where necessary.

4.3 Topsoil Maintenance

CONTRACTOR will implement measures to maintain the topsoil throughout the construction of thepipeline. It is acknowledged that the successful reinstatement of vegetation, which is vital for theavoidance of erosion, along the ROW will depend upon the structure and seed bank of the topsoilreplaced.

Topsoil stockpiles will be monitored. Should any adverse conditions be identified corrective actions willinclude:

* Anaerobic conditions - turning the stockpile or creating ventilation holes through the stockpile;* Erosion - temporary protective fencing will be erected;* Waterlogging - a drainage channel will be cut through the stockpile;* Aggressive weeds - if these colonise the stockpile the stockpile will be turned and a mulch placed

on the surface to prevent further regrowth. In the unlikely event that herbicides are required allapplicable EU regulations will be followed with regard to safety equipment, chemicals to be usedand dosage.

5. SUBSOIL REMOVAL AND STORAGE

CONTRACTOR's approach to subsoil removal and storage to facilitate appropriate reinstatement of thepipeline and facilities is outlined within this section.

Procedures for subsoil removal and storage are detailed in the Construction Method Statement forTrenching, which will be approved and which addresses the engineering solutions. The Method Statementshould be read in conjunction with this Management Plan.



5.1 Subsoil Excavation

CONTRACTOR have developed procedures to address the specific requirements of the contract withrespect to subsoil excavation which include, but are not limited to, the following:

* Depth of excavation;* Width of trench;* Excavation stability; and* Dewatering.

5.2 Subsoil Storage

The storage of subsoil in stockpiles, no more than 3m high with side slopes at a maximum angle of 600,will take into consideration the following:

* Sufficient compaction by the application of downward pressure by excavator bucket, onstockpiles with an expected life over one month, to prevent erosion and wash-out;

* Provision of drainage to surface water run-off from stockpiles and ROW;* Providing vehicular access through the stockpiles;* Dedicated storage locations where the stockpiles will not be compacted by vehicle movements or

contaminated by other materials; and* Segregation from topsoil stockpiles.

In the event that the subsoil stockpiles experience erosion CONTRACTOR will install erosion mattingover the stockpiles as a corrective action in the event that further compaction fails.

6. TRENCH EXCAVATION AND PIPELINE PADDING

CONTRACTOR's approach to trench excavation, pipeline padding and waste soil to facilitate appropriatereinstatement of the pipeline and facilities is outlined within this section. Procedures for these activitiesare detailed in the Construction Method Statement for Trenching which addresses the engineeringsolutions and should be read in conjunction with this Management Plan.

6.1 Excavation

The various methods that CONTRACTOR will employ to excavate the pipeline trench include, but arenot limited to, the following:

* Tracked excavators where normal soils are encountered;* Rip-ditch trenching by bulldozer with a rock ripping bucket in rocks with normal cover; and* Blasting where the depth of rip-ditch trenching is insufficient.

These methods will be adapted by CONTRACTOR on a site specific basis, dependant on groundconditions encountered. The Pre-construction Survey will be used to identify the ground conditions alongthe pipeline route.

In locations where working in the trench is considered a risk the following measures will be taken, but notbe limited to:



* Shoring of the trench walls by sheet piling, lagging or other appropriate means; and* Dewatering of the trench/trench drying in areas of high groundwater. This will be undertaken in

accordance with the Pollution Prevention Management Plan.

6.2 Open trenches

To facilitate access across the ROW during construction activities trench plugs will be constructed bytemporary backfilling of the trench with subsoil and provide crossing points. Stock-proof fencing will beerected around the trench to minimize the risk to livestock. The Construction Team in collaboration withthe Community Liaison team will agree areas of fencing to be installed with relevant communities andlivestock owners prior to construction (refer to Community Liaison Management Plan).

The location of fences will be close to occupied properties or other sensitive areas where they are themost appropriate measure to assure the safety of people, livestock and property. This includes theprovision of fences at the crossing points mentioned above.

In addition to these measures CONTRACTOR will employ watchmen to patrol the trenches and nighttime storage locations whilst discouraging the public from infringing upon the FCI-ROW.

6.3 Blasting

CONTRACTOR will only use blasting where alternative methods of excavation prove to be unfeasibleand/or uneconomic. In those areas where blasting is to be performed a design report will be produced byCONTRACTOR, prior to blasting, that demonstrates how the procedure will:

* Minimise over-break of ground and minimise the generation of spoil material;* Minimise risk of damage to potentially sensitive aquifer systems (by causing rock fractures leading to

disruption and / or contamination of the water), by appropriate selection of explosive material,maximum propagation velocity and the parameters that control it.

All blasting activities will be supervised by a recognised and approved blasting specialist (sub-contractedby CONTRACTOR) familiar with the specified international standard. Blasting will also be performed inaccordance with the Pollution Prevention Management Plan.

6.4 Fill and Padding

Surplus excavated subsoil will be screened, graded and/or crushed by CONTRACTOR for re-use astrench fill and padding as far as is practicable. In the event that sufficient quantities, as demonstrated bycalculation, if acceptable material cannot be recovered from the subsoil stockpiles then CONTRACTORwill seek to extract material from borrow pits on the ROW in the first instance, or consequently fromthird-party borrow pits under agreement and following GGIC approval.

At no time will CONTRACTOR use topsoil for trench fill or padding.

7. REINSTATEMENT OF SOILS

CONTRACTOR approach to the reinstatement of soils along the ROW is outlined in this section.

The reinstatement of soils is classified in the contract specification as either of the following:



* Standard Reinstatement; or* Special Reinstatement

These are discussed below. The specific locations in which the standard or special reinstatement are to beimplemented will be identified during the Pre-construction Survey.

7.1 Reinstatement of Subsoil

In all areas the subsoil will be retumed to the trench such that:

• 95%-105% of measured compaction in adjacent undisturbed areas is achieved;* Final level after settlement is at, or below, surrounding ground.

The subsoil will be returned to the pipeline trench by backhoes and spread in successive thin layers eachof which will be compacted by vibrating plate tampers to the specified degree of compaction.CONTRACTOR will use a 'flat lift' technique to tine the top 300mm (approx.) of subsoil afterreplacement to render the subsoil workable and loose in keeping with the adjacent undisturbed ground.

A joint inspection of the completed works will be performed by CONTRACTOR and GGIC covering, butnot limited to, the following:

* Slope stability;. Relief,* Topographic diversity;* Surface water drainage; and. Compaction.

No further reinstatement will be undertaken until the joint inspection is approved.

7.2 Special Reinstatement

Areas in which special reinstatement is necessary include, but are not limited to, the following:

* Hillsides where benched cuttings are necessary (discussed below);* Boulder fields; and* Water crossings (covered in section below).

Where it is necessary to cut a bench into the hillside CONTRACTOR will restore the slope, as far as ispracticable, to the original contours by filling in the bench.

To ensure adequate drainage of the ROW where bench cuts are made a drainage channel will beconstructed at the toe of the cut face. This channel will become a permanent feature of the slope afterreinstatement.

All materials stripped and/or excavated to enable the pipeline to be installed will be stored andmaintained. Reinstatement of the soils will be carried in accordance with this Plan with subsoil layersarranged so that the outer edges effectively restore the ground level to that documented in the pre-construction survey. CONTRACTOR will ensure that at no time are the reinstated slopes:

* Steeper than the original slope; or* Extend beyond the original line of the slope

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00001 Page lOof 25


CONTRACTOR will reinstate the topsoil by distributing the stockpiles over the site, harrowing thesurface, and reseeding before installing erosion matting.

7.3 Reinstatement of Topsoil

Topsoil will be reinstated separately from subsoil, with care taken to avoid mixing of the materials.

CONTRACTOR will use only the topsoil excavated in the specific location for reinstatement operationsin that location.

The depth of topsoil reinstatement will be sufficient to restore the fertile depth (as a minimum)determined for the specific site during the Pre-construction Survey, initial topsoil strip and visualobservation of the adjacent off ROW land. The depth of topsoil replacement will be a direct reflection ofthat excavated.

To promote fertility in the topsoil thin layers of 'equivalent material' may be added. These materials willinclude, but not be limited to, the following:

* Compost;* Windrowed vegetation; and* Mulch.

When replacing the topsoil CONTRACTOR will programme the works such that the areas furthest awayfrom the stockpiles are reinstated first with reinstatement getting progressively closer to the stockpiles,thus reducing the number of vehicle movements over the reinstated topsoil.

The reinstated topsoil will then be harrowed, where practical, to protect the stability and promotevegetative growth. On steep slopes and/or rocky areas CONTRACTOR will track bulldozers across thereinstated topsoil perpendicularly to the slope to roughen the surface.

Where topsoil is reinstated to agricultural land the surface will be prepared for planting. As a minimumthe soil will be graded and tined to remove compaction. The Contractor will seed and maintain all topsoilstorage areas as defined in the topsoil maintenance procedure and irrigate all areas to the extent requiredto suppress dust formation.

8. EROSION CONTROL

The CONTRACTOR will develop, in conjunction with the Pollution Prevention Management Plan,erosion control measures to prevent sediment run-off into watercourses that are to be implemented duringconstruction, interim reinstatement and permanent reinstatement of the pipeline. Erosion control measuresare to also be implemented where the ROW intersects or runs parallel to the following:

* Watercourses;* Water bodies; or

* Other sensitive areas.

The erosion control measures proposed will be used and maintained throughout the project until the areasof concern have been stabilized and re-vegetated in accordance with the specifications to GGIC approval.The erosion control measures are considered in greater depth in this section.

8.1 Erosion Classes

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00001 Page l lof 25


The erosion control measures have been developed to ensure that the surface profile visual erosioncharacteristics in all project areas are limited to Erosion Class Three (3). This erosion class ischaracterised by the following visually assessed features:

* Wash marks on the slope surface;* Discontinuous rills (channels with a cross-sectional area < 1 m2 and < 30 cm in depth) spaced at

20-50m across the slope; and* Splash pedestals and exposed roots at the original surface level.

The potential for watercourse contamination by sediment carried in surface water run-off from slopescategorised as Erosion Class Three (3) is minimal.

8.2 Temporary Erosion Control Measures

The temporary erosion control measures that will be adopted include, but are not limited to, thefollowing:

* Erosion matting in areas where erosion classes 4-7 have been identified and to aid successful bio-restoration;

* Silt fences in areas of low sheet flow;* Filter berms to temporarily retain surface water run-off;* Straw bale barriers in locations requiring small volumes of sediment interception;• Wooden fences to retain cuttings on side slopes and ridges:* Trench plugs in steep areas to prevent channel flow during periods of heavy rainfall eroding the

trench bottom; and* Sediment traps at the outlets of ROW drainage systems and structures that concentrate the flow of

sediment laden run-off.

8.3 Permanent Erosion Control Devices

The purpose of permanent erosion control measures are to:

* Intercept surface water run-off and convey it to a safe outlet;* Prevent sediment transportation off the ROW;* Reduce surface run-off velocities to safe levels;* Stabilise steep slopes and river banks; and* Prevent trenches acting as drains.

CONTRACTOR will exercise caution when implementing engineering measures that may affect soilhydrology as follows:

* In wetland areas trench breakers will be installed at a higher frequency (every 50m) to limitlateral movement of water; and

* Any diverter berms and other devices to redirect the flow of water away from erosion prone areaswill be designed to limit damage to adjacent vegetation.

Regular monitoring will identify any damage being caused to vegetation and appropriate measures will betaken to either reduce the flow rate or to divert part of the flow into other less vulnerable areas.



8.4 Marking of Erosion Control Works

The Procedure for Preliminary and Final Geotechnical Works - Erosion outlines how theCONTRACTOR will approach the marking of the erosion control works required on the ROW.

The erosion control works will be marked with pegs taking into account:

* Type of control measure;* Topographical alignment;* Spacing;. Orientation;* Material quantities; and* Soil type.

The geotechnical works will be recorded upon the Field Report for Erosion Control Works Form.

9. WATERCOURSES

The water crossing method statements will include:

* all measures, which will allow fish to pass up and downstream, to be taken during pipelineinstallation to minimise the raising of silt and for the measurement of silt loads;

* procedures to ensure that site specific long-term erosion of the banks and river bed is prevented;* Details of diversion pipes and channels sized to convey the mean annual flow rate and which will be

at the same gradient as the river allowing water to enter and exit at the normal channel invert level toprevent water cascading from the pipe or channel;

* Timing of construction which will preferably be during low flow periods, which are most likelyduring the summer season;

* The use of sediment control measures as discussed in this Plan; and* The use of pollution prevention measures discussed in the Pollution Prevention Management Plan.

The method statements will be issued to GGIC for approval prior to start of work on site. In additionimpact upon wetlands will be avoided as much as possible through minor re-routes which will bedetermined following the Pre-Construction Survey.

During route finalisation, arrangements will be made to preserve the function of local drainage, irrigationand other services, which will include diversions and culverting, unless prior agreement has been reachedwith interested parties.

9.1 Watercourse Reinstatement

The following features of water crossings will be reinstated to pre-construction conditions as far as ispracticable with deviations subject to GGIC approval:

* Bed contours;* Bed scour resistance along the line of disturbance through re-use of gravels segregated from

sediment after excavation; and* Bank profiles - to be reinstated within 2 days of backfilling of the pipe trench.

CONTRACTOR will introduce erosion control measures as necessary to minimize the potential forsediment release into watercourses until re-vegetation is established. The measures will also serve to



stabilise the banks, helping to re-establish vegetation. In addition, watercourse crossings will beundertaken in accordance with the Pollution Prevention Management Plan.

In locations where the watercourse cannot be retumed to the Pre-construction condition CONTRACTORwill provide engineering justification of site-specific solutions proposed. Engineering evaluationssupplemental to the specific method statements will consider, but not be limited to, the following:

* Channel flow rate;* Stabilisation of river beds when erosion propagation from unstable channels downstream is likely

to impact upon cover to the pipeline;* Bank stability; and* Potential for accelerated bank erosion and pipe exposure.

All water crossing designs will be made available for review by an international engineering consultantmutually agreed and directed by GGIC, MCG and the MoE. The CONTRACTOR accept that theconsultant may propose modifications to the design in respect to safety but reserve the right to discusssaid modifications and/or propose alternatives prior to implementation thereof.

10. TEMPORARY ACCESS ROADS AND FACILITIES

Following construction of the pipeline, temporary access roads in environmentally sensitive areas andfacilities will be demolished and reinstated to their original condition in accordance with this Plan. Thelocal community will be given the opportunity to decide if new access roads outside of environmentallysensitive areas should remain, otherwise these will also be demolished and reinstated to their pre-construction condition.

Reinstatement of these areas will comprise the following:

* Removal of all facilities and plant;* Removal of all aggregates, hardcore and concrete hardstanding which may either be re-used (if

possible) or disposed in accordance with the Waste Management Plan;* Reinstatement of subsoil and topsoil;* Installation of erosion control measures as required; and* Bio-restoration.

10.1 Management of Reinstatement Waste

This section outlines the approach that CONTRACTOR will adopt to manage the construction anddemolition waste arising from the construction of the pipeline and permanent facilities and from theconstruction and demolition of temporary facilities. The following types of waste are anticipated to beproduced from these activities:

* Natural materials (soil and rock);* Contaminated soil;* Agricultural topsoil;* Worked stone other than natural stone that has been crushed/screened; and* Building materials.

Management of these wastes will be in accordance with the Waste Management Plan but are alsodiscussed below.



10.2 Management of Waste Soil and Rock

This section outlines the approach that CONTRACTOR will adopt for the management of soil and rockthat cannot be re-used or returned to the areas from which they were excavated. The contents of thissection are to be read in conjunction with the Waste Management Plan.

At sites where a surplus' of soil and rock are present the materials will be managed under the followinghierarchy in accordance with the Waste Management Plan:

* Re-use on the ROW* Re-use off the ROW on access roads and facilities* Provision to and re-use by local communities* Disposal at GGIC approved sites off the ROW

Re-use of materials on the ROW will be dependent upon the viability of the material as a constructionmedium. Acceptable materials will be considered for use in the following:

* Infrastructure works;* Stability measures;* Erosion control measures;* Simulation of rock streams and glaciers;* Hillside contour blending; and* Localised increases in the finished surface level on the ROW to allow for settlement.

Re-use of materials off the ROW may be undertaken at the following areas:

* Construction camps;* Road sub-grade;

These applications do not constitute an exhaustive list but serve to illustrate the many options available tothe CONTRACTOR to reduce the surplus.

Provision to and re-use by local communities will be considered by the CONTRACTOR. The materialswill be transferred to third parties when the following can be agreed:

* Feasibility of transfer;* Material specification; and* Terms and conditions for the supply of the raw material.

10.3 Sites for Permanent Disposal of Reinstatement Waste

10.3.1 Waste Soil and Rock

Waste soil and rock is restricted to natural materials, with the following excluded:

* Contaminated soil;* Agricultural topsoil;* Worked stone other than natural stone that has been crushed/screened; and* Building materials.

In the event that waste soil and rock requires disposal off the ROW this will only be undertaken at GICapproved sites. Sites will be identified by the CONTRACTOR that are located away from the following:

ELECTRONIC FILE REFERENCE: NSGPOO1-REOO-EV-PLN-00001 Page lSof 25


* Areas designated as Special Agricultural Land;* Watercourses;* Valley bottoms; and* Open areas with a slope > 300.

CONTRACTOR will develop GGIC approved sites for the disposal of waste soil and rock in accordancewith the requirements of 'Inert' waste disposal sites, with a reduced specification where:

* The waste disposal site is designed to maintain the site stability, local hydrology and landscaperegime;

* The waste disposal site does not require an impermeable barrier to separate it from the adjacentare a;

* The exposed surface will be closed, capped, and landscaped to blend in with the localenvironment using the approaches discussed within this Plan e.g. topsoil reinstatement, erosioncontrol and biorestoration.

Waste disposal sites will re-vegetated as necessary, with erosion matting provided to stabilize the soiluntil the vegetation is established.

11. BIO-RESTORATION

11.1 Objectives

The overall objectives of bio-restoration are to:

* Restore the ecological characteristics and in particular the variety and distribution pattern of plantspecies; and

* Achieve sufficient vegetation cover to reduce erosion to meet the performance target of ErosionClass 3 or better.

Bio-restoration of the pipeline and temporary facilities will be undertaken to meet the followingrequirements:

* Non-agricultural areas - the long-term cover shall be the native flora. The bio-restoration strategyis based on supplementing the seed bank of species remaining in the preserved topsoil withequivalent matenrals (seeds, bulbs, and plants) re-planted after removal from project areas beforeconstruction disturbance and/or from suppliers.

* In agricultural areas - defined as arable and in-bye (close to residential properties). The objectiveis to return the land to the landowner in a state fit for the landowner to re-plant with his own seedcrops.

For sections of the ROW in Erosion Classes 4 and above, all re-vegetation measures will be implementedimmediately if feasible in order to prevent erosion prone surfaces being exposed to heavy rain.

Bio-restoration of permanent facilities i.e. in project areas with permanent surface development will notbe possible and these areas will be subject to landscaping which will utilise many of the measuresdiscussed within this Plan (refer to Landscape Management Plan for details of landscaping for permanentfacilities).



11.2 Agricultural Land

The reinstatement of agricultural land will be undertaken in accordance with the Land Entry Procedurewhich provides details of the reinstatement measures required for agricultural land as agreed with thelandowner and which will vary on a case-by-case basis.

Specific commitments with regard to agricultural land are outlined below.

As a minimum it is expected that the fields will be retumed to their pre-project condition which will beaccomplished as follows:

* CONTRACTOR will seed and maintain all topsoil storage areas;

* Where necessary and agreed with the landowner, CONTRACTOR will irrigate the ROW tosuppress dust formation to avoid damaging sensitive human and environmental receptors,particularly crops;

* CONTRACTOR will not be involved directly in the application of fertilisers, herbicides andother inputs or the planting of seed on agricultural land;

* Any compensation issues relating to crop damage will be detailed in the site specific contractsdrawn up between CONTRACTOR and the Land Owner and will be subject to GIC approval.

Photographs will be taken of the site prior to construction activities taking place and the boundaries andother features of the land will be marked and GPS locations recorded to assist in reinstatement.

11.3 Non-agricultural Land

This Plan refers primarily to the reinstatement of non-agricultural land. Restoration will be undertakentaking three types of plant community into consideration as follows:

* Habitats;* Interim species; and* Species specific, including rare species.

The following sections discuss these communities and the methods which will be employed torestore/manage each one.

11.4 Vegetation Cover

Bio-restoration will be undertaken to achieve the following composition of vegetative cover, followingreinstatement:

* the species originally found in each route section or project area (with the species in their originalproportions, taking into account the expected growth rates of individual species); or

* other species (for example, fast growth types) which are suited to the local environment andindigenous to the region; or

* an ecologically compatible mixture of those two groups.

11.5 Vegetation Management



In addition to the measures outlined above this section provides further details with respect to thefollowing:

* Cultivation and propagation of plants in preparation for bio-restoration and replanting of theROW, temporary access roads and facilities (both permanent and temporary);

* Procedures and considerations for replanting the ROW, temporary facilities and landscapingpermanent facilities; and

* Consideration of bio-restoration maintenance and protection of plants.

11.6 Local Tree Nurseries

Nursery production is considered to be the most suitable method for propagating trees species. For shrubs,given the larger quantities of planting material that would be required, nursery production for mostspecies is not considered a feasible approach. For the most important shrub species seed will be collectedand sown directly on site. With adequate protection measures and tending of the shrubs after planting,shrub regeneration is expected to be satisfactory.

CONTRACTOR has reviewed the possible options for propagating tree seedlings for planting on theROW, and has concluded that local nurseries supported by technical expertise and inputs fromCONTRACTOR will be the most effective means to produce seedlings of the desired quality and quantitygiven that local nurseries offer:

* Flexibility in terms of location and level of inputs from CONTRACTOR;* An opportunity to build links with the local community, which is a vitally important first step to

enable effective measures to be put in place to protect seedlings planted on the ROW;* Reduced losses due to transportation as nurseries will be located close to planting sites; and* A direct benefit for local communities through infrastructure provision and skill transfer.

11.7 Biorestoration Planting

A planting schedule, which will be developed) will feed into a Bio-restoration Schedule which will bedeveloped following the pre-construction survey (this schedule will be flexible depending ultimately onfavourable location planting conditions) including:

* pre-construction transplanting;* cultivation during construction; and* post construction soil preparation, planting and aftercare.

CONTRACTOR will also produce a Bio-restoration Materials Specification following the pre-construction survey describing:

* Species;* Number of each species;* The form of each species to be planted; and* Planting materials e.g. guards.

CONTRACTOR will develop a range of bio-restoration method statements following the pre-constructionsurvey to cover each project area and re-planting scheme. These method statements will comprise:

* The methods which will be used for habitat restoration and* Planting methods statements for specific species



11.8 Scheduling

CONTRACTOR will carry out bio-restoration work in the appropriate growing seasons. Sowing or

planting shall be scheduled for a period that is likely to be followed by sufficient rainfall to promote

germination and establishment.

To assist in the preparation of the planting schedule, CONTRACTOR will identify appropriate growing

seasons using the following:

* The characteristics of the particular plant species suitable weather 'windows' and seasons for

each area of the route; and* Meteorological data from the following sources:

* Historical meteorological data; and

* GIC commissioned survey of meteorological data

11.9 Planting Requirements and Restrictions

Planting of seedlings will be carefully supervised to ensure that seedlings are planted at the correct depth

(soil should be level with root collar) and that the soil is sufficiently compacted around the seedling to

remove air pockets.

For grassland communities the use of fertilizer will be avoided as this may alter the species composition

of the sward. Fertilizer usage will be restricted to slow release fertilizers mixed into tree planting holes

prior to planting.

Trees will not be planted in rows except where contour planting is required on sites with a severe erosion

risk. Although tree shelters can dramatically increase growth rates by encouraging apical dominance, on

most sites it is expected that they will be stolen. If possible, where there is community support for

planting trees, and guards from the local community can be employed to protect the planting site, tree

shelters may be used.

In planting seedlings on the ROW, CONTRACTOR will ensure that container grown trees and shrubs are

planted the same day they are collected from the nursery. If for any reason there is a delay in planting,

the seedlings will be retained in a shaded location and watered daily.

11.10 Plant Protection

In sections where livestock or wild animals are present, precautions will be taken to protect the seeds and

plants from damage. Some or all of the following techniques will be employed:

* security patrols and procedures;* liaison and agreements with livestock managers, which can be undertaken during discussions

with respect to determining crossing points in collaboration with the Community Liaison Team;

* erection of stock-proof fencing (designed / installed to discourage theft), along the project areaboundaries;

* supplement boundary fencing by internal area fencing to give double protection to particularareas.

CONTRACTOR will put in place the necessary physical measures, described above, to protectregenerating vegetation on the ROW. Where possible CONTRACTOR will endeavour to build links with



local communities and involve them in aspects of the reinstatement work (seed collection, plantpropagation, tending and protection of plants and seeds on the ROW).

11.11 Aftercare

CONTRACTOR will carry out the necessary aftercare (watering, weeding, further application of fertiliseretc.) during the contract maintenance period in order to meet the bio-restoration requirements.

Weed control will be undertaken manually and local people will be employed to undertake this work. Anarea of lm diameter will be cleared around all tree seedlings for a period of at least two years followingplanting. Mulches will be used if possible to reduce weed growth and retain soil moisture.

CONTRACTOR recognises that although they will be able to meet their contractual obligations forreinstating the ROW within the required time period this will not necessarily guarantee the success ofROW reinstatement since:

* Most tree species require two years in the nursery prior to planting;* Depending on site conditions (primarily altitude and soil fertility) trees may need protection for

over five years before they reach a height where they are no longer vulnerable to browsing andcan be said to have established successfully.

Given the above, following completion of its contractual duties with respect to the Bio-restorationrequirements, responsibility for management of the reinstatement process should be transferred fromCONTRACTOR to another entity.

12. UNAUTHORISED USE OF ROW FOR ACCESS

12.1 During Construction

The Pre-construction Survey will also assess the suitability of proposed access routes to vulnerable sitesalong the ROW and identify means to avoid or ameliorate any negative impacts on vulnerable habitatsand species.

Access for construction activities will be limited to the ROW and to existing roads in EnvironmentallySensitive Areas as far as is practicable, with any temporary access roads in Environmentally SensitiveAreas removed and reinstated upon completion of construction. A road is considered to exist prior toconstruction if it is depicted as such on official topographical maps.

In order to prevent rutting, which causes subsequent erosion problems, damage to riparian areas andillegal logging CONTRACTOR will implement measures to prevent unauthorised use of the ROW as aroadway

13. TRAINING

Environmental awareness raising is an important element in ensuring effective implementation of thereinstatement plan in particular with respect to the bio-restoration requirements. Training will beundertaken in collaboration with the Training Department, Environment Team and Community LiaisonTeam.



* Specific Craft training will be provided for Plant Nursery Personnel and is likely to comprise aone-week training course covering all aspects of nursery management.

Thereafter, all training will be on-the-job. Nursery managers will be responsible for training nursery

workers (under the supervision of the Environmental Field Officer). Nursery workers will be trained in

seed sowing, watering, shading, hardening-off, weeding and grading of seedlings.

13.1 Environmental Procedure - Soil

The following methods must be employed:

* Various types of soil will be encountered during construction, these must be stored separately.

* Cut and remove all standing crops from the working width. The maximum height of any crop

should not exceed 50mm at the time of top soil stripping.

* Do not remove topsoil in excessively wet weather or when the soil is waterlogged.

* Ensure topsoil is stripped and stored separately from subsoil. There is to be no mixing of topsoiland subsoil. The depth of strip will be agreed on site by a suitably qualified person.

* Recognisable strata, eg peat layers or large stones and boulders, in either topsoil or subsoil is to

be stored in a manner that enables them to be replaced in reverse order to that excavated.

* Store soil adjacent to the area from which it has been taken. Soil from river banks, ditches and

woodland has to be stored separately and very close to the original location.

* Soil stores are not to exceed 3 metres in height, or be driven on, or otherwise compacted by plant

or vehicles.* Store soil lOm away from any watercourse* The surface of top soil piles will be smoothed with the back of an excavator bucket to limit

erosion.* Any soil stored on a flood plain will have gaps left to allow the free flow of flood water back to

the watercourse.* Do not refuel vehicles or plant in the immediate vicinity of stored soil or contaminate soil with

waste.* Do not remove topsoil from its area of origin. This is a pest/disease control measure. However, in

the areas identified as having Working Width restrictions it may be necessary to remove the soiloutside the restricted area and store it in a suitably designated area. Check before this is done.

. Ensure that contaminated soils and excess surplus comply with waste regulations and are

disposed of at suitable locations. Movement of contaminated soil will require the correct

authorisation.

13.2 Soil Reinstatement

The following good practice applies

* The Working Width will be re-graded to reflect the original profile

* Surplus subsoil, if suitable for deposition under topsoil, will be spread on a field-by-field basis

* Topsoil will not be replaced when it, or the subsoil, is soaked or waterlogged

* The subsoil will be ripped to remove soil compaction prior to topsoil replacement. Stones anddebris will be removed prior to topsoil replacement

* After replacement, the topsoil will be stone picked, ripped and cultivated as necessary
