6.1 Introduction

The rationale for impact quantification and significance has earlier been discussed in the

previous chapter. The results indicate that various components would be impacted

positively or negatively. In order to preserve the present integrity of the environment

certain steps have been recommended to mitigate or control the major negative impacts

identified in this study. The control/mitigation measures have been based on the

baseline conditions with regards to the biophysical environment, socio-economic and

health status of the host communities. Also considered were the project activities and

their envisaged impacts and concerns of stakeholders during consultation meetings,

community contacts and socio-economic/health status of the host communities.

6.1.1 Planning Phase

Septa Energy shall:

• Pay adequate compensation for the land take and farmlands in line with Septa

Energy procedure and Federal Government Land use Act.

6.1.2 Site Preparation

B. Socio- Economic

Mitigation measures are measures designed to address the impacts of projects. The

measures are largely a function of the adverse social impacts of projects since it is such

impacts that require mitigation. The expected impacts of the Proposed Gas pipeline

Project include the following:

• Demographic Impacts (influx of people into project area).

• Socio-economic Impacts (redirection of labour, inflation).

• Impacts on Lifestyles (sexual laxity, alcoholism, youth militancy).

• Impacts on Cultural Properties (religious sites/shrines, etc).

• Impacts on Social Infrastructure (schools, health care facilities, water supply).

• Impacts on natural resources (land uptake, destruction of vegetation and farms).

The usual practice is to differentiate these impacts for purposes of analysis. However, In

reality they tend to be closely interrelated. For example, an increase in population

(demographic impact) can increase pressure on natural resources and social

infrastructure. Project activities will be very visible and transient in the pipeline

communities during the construction phase. They will be much less visible in these

communities during the operation phase. This low visibility should not be seen as

reducing the stake of the pipeline communities in the project. The company would

continue to sustain consultation with these communities after the construction phase for

the maintenance of good community relations.

Mitigation Measures

The possible adverse social impacts of the project were spelt out in the previous chapter.

These impacts were derived from experience elsewhere and from the views of

respondents in the host communities of the gas pipeline project. The impacts provide

the basis for the articulation of appropriate mitigation.

Relevant measures needed at each stage of the project, i.e. construction, operation and

decommissioning are indicated in the discussion.

1. Population growth due to in-migration Septa Energy shall:

a. Use local labour as much as possible

2. Redirection of labour from agriculture Septa Energy shall:

a. Make provision for agricultural inputs b. Organize farmers into cooperatives.

3. Inflation in the local economy Septa Energy shall:

a. Make provision for agricultural inputs b. Organize farmers into cooperatives.

4. Pressure on local infrastructure Septa Energy shall:

a. Use local labour as much as possible in order to minimize additional demand for infrastructure

b. Reduce impact on local infrastructure

5. Destruction/Loss of farms Septa Energy shall:

a. Pay adequate Compensation for land take and farmlands

6. Deforestation Septa Energy shall:

a. Minimize land take and use existing ROW as much as possible. b. Facilitate reforestation

j /. '-"'-"'"''-'" ""'" Ul KVVV Septa Energy shall: Liaise with Government and security agencies at all levels

8. Youth militancy/unemployment Septa Energy shall:

Undertake youth empowerment and public enlightenment.

Table 6.2 shows the major mitigation measures required to address each impact.

Population growth, consequent on in~migration, which will be particularly a feature of the

construction phase in all the project areas and the operation phase, may be addressed

through the use of local labour as much as possible. This approach is necessary in order

not to create disaffection in the communities since the local people will find it difficult to

understand why a project located in their area should be beneficial to strangers rather

than themselves. In the decommissioning phase where local labour earlier engaged may

become unemployed, skill acquisition programmes will be necessary.

The mitigation measure of engaging local labour, as Table 6.2 indicates, applies to

several of the impacts. Farmer/farm relocation and compensation are very sensitive

issues that need to be addressed after effective consultation with, and participation of

the local people. Where displaced people are not satisfactorily compensated, the

consequent discontent will adversely affect the effective operation of the project.

c. Health

Some of the activities involved in all the phases of the pipeline project have some

significant adverse potential health impacts. The adverse health Impacts will require

appropriate mitigation measures while the beneficial health impacts will be enhanced.

The proposed mitigation/enhancement measures for the respective impacts are

summarised as follows:

Impairment of health/safety

The focus here is on the health of the communities and the workforce.

The health facilities in the communities will need to be expanded and strengthened with

regard to:

• Number of doctors, nurses, pharmacists, and other paramedical staff in some of the

existing hospitals, and primary health care centres;

• Maintenance of existing infrastructure

• Sustain the supply of vaccines for immunization against communicable diseases,

especially the childhood diseases;

• Maintenance of accurate health statistics through further training;

• Disease control through monitoring and surveillance programmes.

Environmental Sanitation/Waste Management

The objective here is to achieve proper management of refuse, sewage and vectors of

diseases. The Environmental Health Unit of each Local Government Area should be

empowered to manage this.

Refuse Management

The current unsatisfactory refuse management needs to be overhauled. The proffered

mitigation measure includes:

Collections of refuse by households and deposited at designated sites, local councils to

collect from such sites and manage appropriately. The ultimate goal is refuse collection

in waterproof polythene bags in each household. Biodegradable organic matter should be

collected in a separate bag from that of non-biodegradable materials (cans, plastics,

glass etc.). The biodegradable matter can be used for compostlng while the non -

biodegradable can be sold for recycling.

Sewage

The use of sanitary latrines should be encouraged. Households should be encouraged to

use flush toilets with septic tanks. The contents of the septic tanks should be removed at

regular intervals treated and disposed of appropriately.


SEPTA ENERGY. Partners lnPedormance

Disease Vectors

Vectors of disease such as malaria can be controlled by use of bed nets, and spraying of

rooms with insecticides, proper sanitation measures such as clearing of bushes around

houses, elimination of stagnant pools of water and construction of drain channels and

destruction of breeding sites for mosquitoes.

Water Quality Impairment

Boiling and filtering of water for drinking should be encouraged. The ultimate measure is

the provision of regular potable water, accompanied by hygienic practices in homes.

Noise

The present low noise level (38 - 68) dBA should be sustained. In the project area,

excessive noise from heavy machinery used in construction activities requires mitigation

as follows:

• Ear protection devices (muffs) should be provided and worn by construction staff

within the working zone.

• Provide functional acoustic environment in campsites lodgings near construction

sites.

• Silencers and mufflers on the exhaust systems of construction equipment.

• Deploy low noise type equipment

• Execute noisy operations during the day rather than at night.

Housing

Housing shortages will become more acute with influx of people into the communities.

The problem associated with housing can be solved by:

• Encouraging private housing development by investors by supporting them.

• Septa Energy or sub-contractor to provide housing for its field staff by managing a

base camp

• Planned development of available land to be encouraged with the assistance of the

Department of Town Planning, Local Government Councils, and State Government.

• Education on overcrowding and spread of contagious diseases

Health Education

Most of the mitigation measures recommended up to now need proper health education

to succeed (e.g. control of infectious diseases, sanitation etc). Success of the health

education programmes depends on the Involvement of health education specialist to

develop suitable materials and train participating staff.



The health impacts discussed above shall be reduced to the barest minimum when

indigenes are engaged in the project.

The Environmental Management Plan has the following specific objectives:

• The adoption of a systematic procedure to ensure that the Project activities are

executed in compliance with all applicable legislations and SEPTA HSE (and other)

policies and guidelines;

• Demonstrate that mitigation measures for all impacts and effects have been put

in place and that the measures shall be adhered to throughout the project

development life cycle;

• Demonstrate that effective recovery measures for managing 'lost control'

situations are in place throughout the Project life cycle;

• Establish a structure that will ensure compliance by SEPTA, Accugas and its

Contractors with the EMP.

7.3 Social Management Plan

This is essentially concerned with the social action plan (SAP) for the host communities.

SAP consists of measures designed to mitigate the adverse social impacts of projects.

Among other things, SAP lists mitigation measures, the means by which the measures

will be implemented, the time schedule for the implementation, as well as the

implementing agency. SAP is therefore based on clearly identified mitigation measures.

These measures are usually designed in collaboration with host communities in order to

engender a sense of ownership. This can be achieved by holding wide-ranging

discussions with cross sections of the communities. This is necessary for the success of

the measures.

Mitigation

It is clear from literature and from experience that development projects do generate

some adverse social impacts, in addition to other positive effects. Mitigation measures

are therefore designed to address the adverse impacts. The mitigation measures for the


SEPTA ENERGY. Partners In Performance ENVIRONMENTAL IMPACT ASSESSMENT OF UQUO·USUNG NEAR ORON GAS PIPELINE PROJECT AKWA IBOM STATE

respective adverse social impacts were spelt out in previous chapter. On the basis of the

proposed mitigation measures, a proposed SAP is provided in Table 7.1:

Table 7.1: Proposed Social Action Plan

Location

The Location of the activities would depend on the nature of the activity in question.

For 1 (a) and (b), recruitment should be coordinated at the District or Local

Government Headquarters, while training can either take place in the

Headquarters or wherever Septa Energy has the facility, depending on the level of

training required.

2 (b) and (c) should be coordinated in the District or Local Government

Headquarters.

3 (a) and (b): Same as (2) above. The activity may involve upgrading or

rehabilitation of roads.

4 (a) and (b): To be coordinated at the District Headquarters and the Local

Government Headquarters. Work on infrastructure should be in all sizeable host

communities.

5 (a) and (b): To be coordinated at the District Headquarters and Local

Government Headquarters. Relocation and compensation should take place in

the affected host communities.

6 (a) and (b) to be coordinated in the Local Government Headquarters.

Reforestation should take place in affected host communities.

7 (a) and (b): To be coordinated in the Local Government Headquarters. The

health education pr~gramme should take place in all host communities.

8 (a): To be coordinated in the Local Government Headquarters. 8 (b): To take

place in local police stations.

Monitoring and auditing

The monitoring and auditing of the activities can be handled by the same team. The

auditing functions should consist of examining the number, state and efficiency of the

activities while they are being put in place. On the other hand, the monitoring function

will involve periodical checks to ensure that the activities/facilities are working properly.

The monitoring and auditing programmes should involve visits to activity sites/host

communities, in conjunction with local/community leader.

Monitoring is particularly necessary in the case of youth militancy and disruptive

activities. The experience in other parts of the country, particularly the Niger Delta

region, has shown that militancy and the associated disruption of activities usually

emerge gradually. The implication is that with effective monitoring any discontent could

be effectively addressed before it becomes disruptive.

7.4 Health Management Plan


SEPTA ENERGY- Partners In Performance ENVIRONMENTAL IMPACT ASSESSMENT OF UQUO-USUNG NEAR ORON GAS PIPELINE PROJECT AKWA IBOM STATE

To address the health problems enumerated above, a health management plan is

incorporated into the project plan (Table 7 .2). The health management plan provides the

measure of assessing the accuracy of the project impact and monitoring of the

effectiveness of the proposed mitigation measures. The present relatively low health

status of the communities would be improved if the mitigation measures suggested

below are implemented.

7 .s Project Specific Waste Management Plan

The Plan will include procedures for safe handling, control and disposal of projected

generated waste in accordance with the company procedure.

Wastes emanating from operational activities are mainly effluents, atmospheric

emissions, spent oil and pigging wastes. These wastes shall be handled in compliance

with the Petroleum (Drilling & Productions) Regulations, 1969, Sections 25, 36 49 and

(b), (c) and (d), which stipulate inter alia that:

"The licensee or lessee shall adopt all practical precautions, including the provision of up

to-date equipment to prevent the pollution of inland waters, rivers, creeks, water

courses, the territorial waters of Nigeria or the high seas by oil, mud or other fluids or

substances which might contaminate the water or marine life, and where any such


SEPTA ENERGY. ENVIRONMENTAL IMPACT ASSESSMENT OF UQUO-USUNG NEAR ORON GAS PIPELINE PROJECT AKWA IBOM STATE

pollution occurs or has occurred, shall take prompt steps to control and, if possible, end

it."

Waste Management Strategies

The strategies of waste management for the proposed project are summarised as

follows:

• To reduce the volumes of wastes generated through appropriate technology,

• To recycle and re-use wastes where appropriate,

• To treat hazardous waste and make them inert before disposal

• To ensure safe and responsible collection, separation, storage and disposal of all

wastes.

• To provide auditable records of all waste streams.

• To monitor waste disposal"activities in order to prevent future liabilities.

• To reduce the negative impact of our activities on the environment.

Waste Management Options

a) The Environmental Management activities of the Uquo to Usung Gas Pipeline

Project are to be implemented in line with Septa Energy policy on waste

management strategies arising from the project as follows:

i) Drums I Containers

Metals and plastic containers are used for a wide range of lubricants and chemicals and

they invariably contain variable quantities of residue. In order to reduce these residual

effects, the following would be considered:

~ Bulk transport and storage for high volume consumption items.

~ Refill and reuse of containers. Where possible, non-refillable containers could be

returned to the vendor for reuse or to company specializing in container

refurbishment.

ii) Industrial wastes

These include electrode studs and scrap metals, plastic caps for protection of pipeline

ends. These shall be disposed off site. Plastic caps may be reused or returned to the

vendors.

iii) Garbage - Solid Waste



These include plastics, paper, food waste and general garbage. In the area, the plan

considers the idea to:

> Reduce packaging wastes such as paper and plastics by the use of bulk handling

systems or "big bags"

> Segregate components such as wood, plastics and paper for recycling or reuse or

incineration. Paper wastes are shredded at designated points.

> Felled tree trunks shall be donated to the indigenes for use as fuel wood.

> Compost organic garbage for agriculture.

> Sawn timber used for pipeline support shall be disposed off appropriately or allowed

to biodegrade at site.

iv) Pigging Wastes, Grit and Condensate

> Improve housekeeping procedures to reduce the volume of solids collected in water

storage tanks.

> Sludge, pigging waste condensate containing significant oil are reclaimed either on

site or off site for the removal and recovery of hydrocarbons and recycle at CPF. If

this is not possible, it will be sent to DPR approved TDU for incineration.

> Grit from pigging activities would be given to construction companies to be mixed

with bitumen for road construction.

v) Sanitary I Medical Wastes

These include but not restricted to soiled materials, used needles and syringes, expired

drugs and materials, blood and blood products, microbial cultures and stocks. The

disposal methods include incineration and burial. A waste consignment note shall cover

clinical waste disposal by contractors.

Waste Segregation Guidelines

For effective implementation of appropriate disposal methods, it is important that wastes

are segregated at source. It is the responsibility of contractors, during their operations to

provide enough clearly marked bins at strategic locations to ensure this. Particular

attention should be given to work areas where a variety of wastes are generated like

kitchen and living quarters.

The differential colour codes for the waste containers are:

• Food I vegetation .................................. Green

• Glass waste ............................................. Biue

• Plastic waste ......................................... Brown



• General (un-useable) ......................... Black

• Medical waste (combustible) .............. Yellow

• Toner I developer.............................. White

The segregated waste shall be handled in the same way as it is handled by Eket LGA

contractors for collection and effective disposal of domestic and garden waste using the

method of landfill at various dump sites, sale of photocopier drums to scrap buyers for

reuse or recycle.

Sources and Inventory of Wastes

Wastes are expected from bush clearing, excavation, domestic wastes from base camp,

pigging and atmospheric emissions from engine exhausts.

7.5.1 Contingency Plan

SEPTA ENERGY has established a contingency plan for prompt and effective response to

emergency situations as may be detected near a public or private building or near SEPTA

ENERGY pipeline facility or explosion occurring near or directly involving SEPTA ENERGY

pipeline facility, as well as fire disaster near or directly involving SEPTA ENERGY facility.

Pipeline surveillance shall be maintained through regular patrols. The first indication of

an emergency may come from one or several sources, depending on the type of

emergency. It may come from within the Company or from outside - from employees,

customers, the public, civil authorities such as Police or fire services.

No matter what the source, an indication that an emergency exists shall be evaluated

(verified as true or proven false) without delay. If an emergency involving Company

facilities is verified, a course of corrective action shall be pursued with the utmost

diligence.

Pipeline emergencies (whether a notice is received, or discovered directly, by field

personnel) will immediately be reported to the Pressure reduction and Metering Station

Control room, which shall become the "clearing house" for information and plans

regarding appropriate responses. The control room shall be staffed to receive and record

all internal and external reports 24 hours per day, 7 days a week. The Supervisors of

control Room shall be administratively responsible for reviewing all emergency

notifications and actions taken each day. Each notification of a pipeline emergency shall

be recorded on the "Notice and Disposition of reported Happening" form, using all



available details and information. The Control room Supervisor shall be notified of the

following emergency situations within a nominal 15 minutes (i.e., "as soon as possible")

after discovery. For this purpose, "emergency situation" is defined as any of the

following events:

• Rapture or leak in a pipeline or related facility.

• Other pipeline or related facility event which causes a public evacuation or closes

a public road;

• A serious injury to an employee or contractor that requires medical attention (or

a fatality);

• An "environmental" event that involves a reportable (or potentially reportable)

release of hydrocarbons or other chemicals;

• Any accident that has the potential to involve local, state or nationa1 media

attention.

When a possible emergency is initially identified in the Control room Office, the Control

room supervisor on duty will immediately notify the appropriate Operators/supervisors

for field evaluation, response and for taking the necessary steps to effect immediate

implementation of the emergency action that applies to the situation. The names of

essential Company personnel (and means of contacting them) shall be listed on a "Key

Employee emergency action telephone List". Each Area Operations Engineer (and higher

level of management) shall be responsible for reviewing the Emergency Call Lists

affecting their area of operations and reporting needed changes to names or contact

numbers to the QHES Coordinator, who shall administratively be responsible for issuing

updates to the lists as needed.

The contingency plans for the envisaged emergencies include:

• Maintenance of functional firefighting equipment and fire fighting team with an

"on scene commander" on duty 24 hours daily.

• Presence of portable fire extinguishers on the premises of all consumers and

training of fire fighters/wardens for all consumers. Occasional activation of fire

drills to keep fire wardens/consumers alert.

• Telecommunication facilities to inform Control room, Police (serious fires), the

exact location of the fire and to mobilize assistance from SEPTA ENERGY and 1 or

state fire service authority for serious I major fires.

• Purchase and maintenance of ambulance vehicle with medical facilities for first aid

and evacuation of wounded personnel during fire outbreaks 1 injury to employee

or contractor.

• Provision for closing blow down valve that vented gas could be ignited.



7 .5.2 Audit Plan

An audit programme shall be in place to review and verify effectiveness of the EMP and

Environmental Management System (EMS) in general. It shall include audits by auditors

independent of the process or facility audited. Audit follow-up shall be timely, thorough

and auditable. A schedule of environmental audits/reviews will be developed for all

phases of the project to monitor site activities and the effectiveness of the EMP. Reviews

and audits will be carried out including reviews of design drawings, specifications and

other documents to verify that environmental objectives and requirements will be

satisfied. Audits of site operations at key stages and during the construction phase will

be conducted to ensure procedures are carried out in the field. Particular emphasis will

be placed on reviewing activities carried out in any environmentally sensitive areas.

7 .5.3 Training Plan

A training programme is an essential part of an EMS. Environmental Training will be

given to key operators on those who are responsible for informing their teams. Topics

will include pertinent environmental legislation, health and safety procedures,

environmental awareness, and identification of environmental risks, and the plans and

actions, which the project is committed to carry out as part of the EMP.

7.5.4 Abandonment Programme'

The facilities for the Uquo to Usung pipeline project are designed to serve the planned

useful life of the project after which they shall be decommissioned and abandoned. It is

the policy of SEPTA ENERGY to carry out abandonment of its facilities in a safe and

environmentally responsible manner such that it constitutes no harm to the environment

and health of the host communities through various remediation strategies to the status

quo ante as far as possible.

Physical abandonment of the facilities is the reverse of the construction and

commissioning process. The technical aspects, HSE studies, detailed engineering and

abandonment execution planning would normally be undertaken before the actual

implementation of abandonment. Generally, abandonment would be carried out in a

structured manner. Prior to abandonment, the drawings and inspection records for all

the facilities and each item of the equipment shall be obtained to determine their status

and integrity as well as personnel, spares and special tools required to perform the

demolition of the facilities - heavy life equipment, specialists etc. and all authorization

for the work to be carried out safely shall be obtained. These include:

• Permit to work procedure (PTW system)


SEPTA ENERGY. Partners In Performance ENVIRONMENTAL IMPACT ASSESSMENT OF UQUO-USUNG NEAR ORON GAS PIPELINE PROJECT AKWA IBOM STATE

• Permit to work in confined 5pace, and

• Permit for excavation work.

The abandonment process will involve the following:

• Plant shutdown

• Removal of all hydrocarbons from system

• Purging of buried pipeline with inert gas such as Nitrogen

• Dismantling I removal of all surface facilities and safe-guarding of facilities I parts

• Capping and sealing of all open ends of buried pipeline

• Remediation of impacted sites in order to restore them to their original condition

as far as possible,

• Civil structures shall be broken up and disposed off at approved sites or handed

over to the host communities for use. Pavements shall be scarified and prepared

for re-vegetation.

Handover of site:

SEPTA ENERGY will maintain a record of the abandoned facilities and a copy will be given

to the Department of Petroleum Resources (DPR), FMEnv, host communities and other

stakeholders.

7.6 Environmental Monitoring Plan

The FEPA (FMEnv) interim guidelines and DPR EGASPIN (2002) Provisions require

environmental monitoring for E & P operations. Monitoring may require the installation of

boreholes or wells within and on the margins of the site with facilities for sampling of

ground water (or leachate in the waste), and sampling and analysis of emissions and

effluents to the environment.

Monitoring will be for two purposes:

• To verify company's compliance against the approved EMP and Regulatory

requirements ;(DPR, State Ministry of Environment)

• To identify any sign of environmental degradation within the project area, resulting

from Project activities.

• Monitoring reports will be submitted to regulators (DPR, State Ministry of

Environment) twice a year for review. Meanwhile anomalies/non-compliance will

receive immediate attention.

• DPR, State Ministry of Environment and FMEnv shall fully participate in the Monitoring Plan

7.7 Project Management Team

The management structure of the Uquo to Usung Gas Pipeline Project will change as it

moves from Design/Procurement phase, via Construction/Commissioning phase to

operation phase. The respective teams will be responsible for the implementation of the

environmental management considerations associated with each phase of the project.

The task of executing the Uquo to Usung Gas Pipeline Project in a sustainable manner

and ensuring protection and conservation of the environment are vested in the Project

Team Manager. This is to guarantee management commitment to all environmental

issues concerning the project including:

• Ensuring compliance with the project EMP by all staff and contractors involved in the

project.

• Interfacing with SEPTA ENERGY and Authorities (FMEnv and DPR) and other agents

(PHCN) on project related environmental matters;

• Overall co-ordination of project related environmental matters;

• Further development, implementation and revision of the Environmental Management

Plan and procedures;

The project team manager may delegate some or all of these responsibilities to other

staff in the SEPTA ENERGY organization but he will ultimately remain accountable for the

successful implementation of the EMP.

Resources and Responsibilities

For the project, the Environmental Liaison Officer (ELO) must possess a thorough

knowledge of site conditions, and must be appointed to the project team. During the

detailed design phase, this officer has the responsibility to liaise with all parties involved

in the project, especially the engineering team and environmental consultants. He shall

provide advice on environmental matters in conformity with SEPTA ENERGY QHSE

guideline and policies.

However, to adequately cover the monitoring, inspection and reporting requirements of

the construction and operations phase, greater resources will need to be deployed. Two

options are apparent:

(i) Establish within SEPTA ENERGY an environment-monitoring group as indicated in

Table 7.4



Table 7.4 Environmental Monitoring Group

Position Requirement Environmental Project Manager Permanent 1 Inspector (HSE Supervisor) Permanent in construction

Part time during operational and ROW maintenance

1 Noise, 1 Air Quality and 1 each of Part time Water Quality, Soil, wild life and Vegetation Experts Laboratory support As required with QA/QC back UlJ support Specialist technical support As required, production chemistry laboratory

or Accredited Laboratory

(ii) Contract

The alternative to an internal environmental monitoring group is to contract out the job

to an appropriately qualified group.

SEPTA ENERGY has established schedules for responsibility to which all levels of staff

owe accountability. Responsibility of environmental issues lies with the management

through a specialist whose role is advisory. SEPTA ENERGY management however,

affirms total commitment to ensure that all environmental considerations are integrated

into related activities. Induction and training courses for staff are part of an effective

environmental management scheme which SEPTA ENERGY holds in high regard.

7.8 Undertakings

Throughout the planning of this project, SEPTA ENERGY will continue to consult with the

public, statutory authorities and affected individuals as well as local communities in order

to ensure that the pipe laying activities and operation have minimum adverse

environmental impacts.

To further support its policy on the environment, SEPTA ENERGY would undertake to:

• Prepare a detailed restoration and after-care plan for maintenance of the pipeline

working width (ROW);

• Monitor all environmentally sensitive areas during pipeline construction and

operation to ensure compliance with SEPTA ENERGY and statutory standards;

• Land uptake for temporary use, which will require clearance, will be kept to the

barest minimum, and restoration after use will be undertaken;

• At crossings of rivers normally subjected to domestic use, commercial and

industrial traffic, construction time will be reduced to minimal and restoration of

riverbanks to avoid erosion will be undertaken.

7.9 Decommissioning and Abandonment

At the end of the life span of the Gas pipeline Project. SEPTA ENERGY shall invoke its

standard decommissioning and abandonment programme. The tasks shall include the

following:

• Ensuring that the decommissioning and abandonment are done with the same care

and respect for the environment with which the project was designed, constructed

and operated.

• Assessing residual impacts that the project has had on the environment during its life

span.

• Monitoring the abandoned environment.

• Restoring the environment to its original state as much as possible.

To accomplish these, the decommissioning and restorative/rehabilitation programme

shall be managed by a team of competent personnel including the Environmental Liaison

Officer (ELO) as well as Engineering and Operations personnel.

2 DESIGN BASIS

ORON pipeline is designed as underground and shall be protected against external corrosion by

high integrity external coating system supplemented by an impressed current cathodic

protection system. Pipeline shall be protected by cathodic protection station (CPS) located at

UGPF. Temporary protection with sacrificial anodes shall be provided for the period from the

beginning of the pipeline construction till the commissioning of impressed current installation.

2.1 SITE SURVEY

Prior the installation of the CP system facilities site survey shall be taken by the CP Contractor

along the pipeline route in order to:

• define soil resistivity,

• define type of terrain,

• define crossing and other neighboring structures (other pipelines, overhead power lines,

rails),

• determine location of test posts.

Soil resistivity measurements shall be taken along the pipeline route, according to requirements

given in 1204501-ILFL-SPC-G-0001.

Since site survey report is not available, following assumptions are taken into consideration

during design:

•

~· •

•

soil is corrosive or slightly corrosive, resistivity <1000m,

there is no electrical railway crossing,

there is no expected crossing or parallelism with high voltage overhead transmission line,

there is no expected crossing or parallelism with low voltage overhead line which could

impact on the pipeline and its CP,

• there is no cased road crossing,

• there are no neighboring cathodically protected structures along the pipeline route.

Cathodic protection of UGPF and Adanga - Calabar pipeline do not impact on the pipeline

CP and vice versa, because of high integrity external coating system,

there is no cathodic protection station at OGRF.

Above mentioned assumptions shall be verified by Contractor after site survey report is

available.

More demanding result from two stated above is taken into consideration, therefore 15 anodes shall be provided for the entire pipeline length as a temporary cathodic protection. It is proposed

to install 5 galvanic anodes stations distributed at similar intervals along the pipeline, each

containing 3 anodes.

3.3 PIPE-TO-SOIL POTENTIAL

Taking into consideration that pipeline is routed mainly through swamp areas, stricter criterion

for pipe-to-soil potential shall be considered. Therefore off potential at the end of the pipeline

shall not be less negative than -0,95V w.r.t. Cu/CuS04, keeping in mind that off potential -1, 15V

w.r.t. Cu/CuS04 shall not be exceeded at any place.

Off potential at drainage point corresponding with assumed potential at the end of the pipeline is

calculated using following equation:

Excosh oc: L Eo = cosh oc: (L - x)

Where:

Eo Pipe-to-soil potential at drainage point (V),

Ex Pipe-to-soil potential at the end of the pipeline (V),

a Pipeline attenuation constant (m·\

L Pipeline length (m),

x Distance between drainage point and end of the pipeline (m).

-0,95 * cosh0,0000113 * 37000 Eo= cosh0,0000113(37000- 37000) = -l,034V

To ensure required off potential at the end of the pipeline, -1 ,034V w.r.t. Cu/CuS04 off potential

at the drainage point shall be set, which is less negative than the most negative potential

allowed (-1,15V w.r.t. Cu/CuS04). It shows that the pipeline could be protected on the entire

length only by UGPF CPS without exceeding allowable -1,15V w.r.t. Cu/CuS04 at any place ..

3.4 CP SYSTEM CONFIGURATION

Taking above calculations and assumptions into consideration, following cathodic protection

configuration shall be applied.

Drawing No. 1 presents the pipeline CP simplified configuration. The pipeline section between

UGPF and OGRF shall be protected by the extended UGPF CP station. The pipeline section

between OGRF and Tie-in to Adanga - Calabar pipeline is installed under the water and isolating joint cannot be installed there. Therefore this short (about 2,5km) section shall be

cathodically protected by the Adanga - Calabar pipeline CP system. There is also no possibility to install test stations at OGRF - Tie-in section, so the pipeline CP system ends at OGRF incoming isolating joint.

Cathodic Protection Station

UGPF plant piping is protected by impressed current cathodic protection installation consisting of deep anode ground bed and transformer rectifier unit. Transformer rectifier is sized for 30A

current output, while ground bed for 25A. Calculations of UGPF CP system shows that maximum current demand is 15A and it covers pipelines, hydrants and station earthing requirements. Therefore there is 1 OA spare current output which could be used for the pipeline protection and there is no need to provide new CP station.

Transformer rectifier DC output (negative) is connected to Negative Junction Box which distribute DC current to Bond Boxes (4 Nos.} and through resistor to existing outgoing pipeline. Negative Junction Box shall be extended to accommodate additional resistor (same as existing)

I and feeder for the designed pipeline. It shall provide DC current to the pipeline and allow

potential adjusting to required value. For details please refer to UGPF Negative Junction Box Extension- Doc No. 1204501-ILFL-DRA-E-0011.

3.1.2 CLEANING PIG RUNS

Before starting any water filling and hydro-test pressure works on the pipeline, the Vendor shall

have undertaken cleaning pig runs using a series of scraper pigs and swabbing pigs, to ensure

that all extraneous materials have been removed from the pipeline section and that

the respective section is sufficiently clean to permit water filling to commence.

The Company shall make the final decision in respect of pipeline cleanliness, and if so required,

the Vendor may require undertaking additional cleaning runs.

3.1.3 GAUGING PIG RUNS

After line cleaning is completed, the Vendor shall be required to carry out a gauging pig run with

an aluminum plate fixed behind the first cup rubber of the pig.

The size of the gauging plate shall be 98% of the minimum nominal internal diameter minus 10

mm of the test section and shall be made from 10 mm thick aluminum.

Gauging pig runs shall have an induced back pressure of 0.5 bar minimum adjusted at

the receiver end.

The gauging run shall help identify obvious reductions in pipe bore caused by buckles, dents,

wrinkles or flattening. The introduction of the gauging pig into the pipeline and removal of

the pig from the pipeline shall always be undertaken in the presence of the Company. UNCONTROLLED UNLESS WITH ORIGINAL SIGNATURES

The quality of the water has to be analyzed by an accredited laboratory according EN 12502

and the report delivered to the Inspection Authority and the Company.

The Vendor shall be required to minimize water volumes used in the pipeline hydro testing

process. Wherever possible, water shall be passed from one completed test section into

the next adjacent section passing downstream between the various test sections wherever

practicable. The procedure of water filling and removal of the sections shall be approved by

the Company.

For the prevention of vacuum (air locking) during the water filling, the minimum back pressure of

the air in front of the pig and the water filling has to be 0.5 bar higher than the pressure of the water column plus 0.5 bar reserve pressure at the highest point in the filled water line.

The filling has to be performed with a filling rate of 0,5 - 1,0 m'/sec, with minimum two pigs with

a water batch in front of the pigs and a water batch of approx. 200m between.

The filling should be performed without interruption, and the design of the suction line of

the pump should prevent sucking of air and foreign material.

Venting of all devices, valves and nozzles shall be carried out.

When the test section is completely filled, a period of time shall be permitted to allow thermal

stabilization between the soil temperature and that of the fill water.

The Vendor shall also consider the use of environmentally suitable and non pollutant chemicals

to prevent internal corrosion of the pipeline section.

The Company shall be required to approve any corrosion inhibition products to be used by

the Vendor prior to any use of such products.

3.1.6 HYDRO TEST PERFORMANCE

The hydro test work shall always comply with the agreed number and characteristics of equipment, materials and installation, the established safety precautions and the number and

qualification of people assigned to the hydro test procedure.

Special points such as major crossings are to be installed using pre-tested pipe, where shown in the crossing list. Those crossings installed with pre-tested pipe may also receive a final

hydrostatic test, along with the rest of the pipeline section.

All testing operations shall be directed from one end of the pipeline section where work is being performed.

Supervisory personnel of the test shall remain at this test point, where pressure and temperature measurement and recording instruments shall be installed in a mobile

measurement trailer.

At the other end of the section, a pressure gauge and thermometer recorder shall be installed

and shall be attended.

Additionally ground I pipe wall temperature probes shall be installed at selected locations along

the pipeline, normally 0.5 km from the ends and in distances of 2.5 km. These probes shall be installed at the same depth as the pipe itself to help substantiate any pressure losses due to

thermal variations.

Pressure test

The pressure test has to fulfill the requirements of ASME 831.8.

Before pressure test a drain test shall be made for calculation of the air content in the pipeline.

The water drained or injected into the pipeline shall be carefully measured and the quantity,

together with times, temperatures, pressures has to be properly recorded. The pressure rise

and reduction shall not be faster than 2 bar/min.

Leak test

The leak test has to fulfill the requirements of ASME 831.8. The duration of the tightness test is minimum 24 h.

The Vendor shall then conduct a complete repair in accordance with the approved instructions

and the specifications.

On completion of repair the Vendor shall repeat the entire hydrostatic test activities according to

the project requirements described previously.

3.1.7 AFTER TESTING

Dewatering

After hydrostatic testing the pipeline shall be completely dewatered by using sufficiently sized

air compressors to launch the dewatering pigs, previously installed in the section prior to filling

the line. These pigs shall be driven from the launcher end of the section towards the receiver

end. The pigs will drive the hydro test water, and where possible, the water shall be transferred

into the next adjacent test section. Any additional fill water volumes and water additives needed

for the adjacent test section shall be added as necessary.

Pressure test sections are often limited by compressor capacities needed to empty the pipe

section. Therefore the Vendor shall bear in mind that length and difference of geodetic elevation .

of the section is selected such as to allow proper emptying of the line.

Before starting dewatering the Vendor shall submit to Company a detailed procedure for

approval.

During any drainage operations, Vendor shall make the necessary arrangements for the drained

water to be suitably disposed of, in order to avoid pollution, damage to crops, to land, to existing

works, obstructions to traffic and to comply with planning approval agreements, The water may

be drained and disposed back to the waterbody from where it came or to another discharge system, which is defined in the planning approval notification. The Vendor shall comply with

the requirements of the water authorities. Vendor shall therefore bear in mind these provisions

during the scheduling stage of hydrostatic tests. ·

Swabbing Pig Runs

Once dewatering of the section is completed the pipeline section shall be dried to an acceptable

level by use of foam swabbing pigs to remove any free residual water. Once the foam pig runs

have been completed and the Company accepts the level of drying, the previously tested block

valve fabrications shall be installed in the line and the valve ball fully opened prior to the calliper

survey.

At the end of the testing and drying operations, the Vendor shall remove the provisional pig

traps as well as other temporary installations connected with the test. He shall also complete

the tie-in of the pipe sections to the previously tested section of pipeline and carry out all work

according to the project specifications and procedures described in this specification. These .

100% ultrasonically inspected.

Drying

Drying operations shall commence immediately after completion of the dewatering operations of

the hydraulic test section.

Pipeline section drying shall be continued until a water dew point of -10° C is obtained.

Pressure, flow, temperature and dew point shall be monitored at the inlet and outlet ends.

Pipeline drying shall be carried out by introducing a large quantity of dry air into the pipeline

section at a low pressure (1 to 2,5 bar at inlet) so as to maximise water absorption. The air

before being introduced into the pipeline shall be dried to a dew point not less than 20°C below

the dew point value specified for the pipeline.

The dry air shall be used to drive high sealing pigs in a pig train. Each pig shall be separated

from the other by at least 250 meters of pipeline.

Pigging of the pipeline section shall continue until the water dew point of the air measured at

the pipeline end remains below the specified dew point and does not fluctuate more than 4°C

whilst a new pig is sent in the line. When the specified dew point is maintained, drying is

completed and the pipeline shall be blocked in at a pressure of 1 bar.

Contractor shall prepare a procedure defining pipeline drying including, but not limited to:

• Drying method procedure description, to be defined of the basis of environmental local

information and prescribed water dew point, complete of acceptance criteria,

Community: Grievance Mechanism (SOP X/XXX) Revised: j Authorised by:

Community Grievance Mechanism (SOP X/XXX)

A. Purpose

The purpose of this procedure is to outline Septa Energy's approach to accepting, assessing, resolving and monitoring grievances from those affected by Septa Energy's activities including its contractors' activities.

Grievances can encompass minor concerns as well as serious or long-term issues. It is essential to have a robust and credible mechanism to systematically handle and resolve any complaints that might arise in order that they do not escalate and present a risk to operations or the reputation of the company (nationally or internationally). If well-handled, an effective grievance mechanism can help foster positive relationships and build trust with stakeholders.

This SOP should be considered in parallel to the SOP related to Stakeholder Engagement due to the inter-relationship between these two activities. It has been designed to meet the requirements of the IFC in relation to Performance Standard 1.

The mechanism for addressing employee grievances is separate and is outlined in the Human Resources Policy.

B. Scope

This procedure will be applied to community complaints and grievances, perceived or actual, at all existing and new Septa Energy facilities, properties or assets owned (in full or part) and /or operated by the company in order to manage the company's risks and relations with stakeholders. The procedure applies for the entire operation lifecycle (including exploration and planning, evaluation, construction, operation and closure).

A complaint or grievance is an issue, concern, problem, or claim (perceived or actual) that an individual or community group has related to Septa Energy and its contractors' operations and activities.

The mechanism does not impede access to judicial or administrative remedies.

C. Application

This Grievance Mechanism provides guidance to all Septa Energy employees and contractors on receiving, registering, assessing and resolving community complaints or grievances emanating from Septa's operations. The fundamental objective of this mechanism is to:

• Provide a predictable, transparent, and credible process to all parties for resolving grievances, resulting in outcomes that are seen as fair, effective, and lasting.

• Build trust as an integral component of broader community relations activities.

• Enable more systematic identification of emerging issues and trends, facilitating corrective action and pre-emptive engagement.

F. Guiding Principles

To maximise the effectiveness of the Grievance Mechanism, Septa Energy shall uphold the following values during implementation and operation of the system 1:

• Commitment to fairness in both process and outcomes; • Freedom from reprisal for all involved parties- within Septa and in the

community; • Dedication to building broad internal support for the grievance mechanism across

project lines; • Mainstreaming responsibility for addressing grievances throughout the project.

rather than isolating it within a single department; and • Willingness by senior management to visibly and sincerely champion the

grievance system.

In addition, the following principles guide Septa's Grievance Mechanism procedure:

1) This grievance mechanism complements and reinforces Septa's wider stakeholder engagement activities. Proactive engagement is essential for good relations with communities and stakeholders. The Grievance Mechanism should not be implemented in isolation.

2) Septa Energy will proactively inform affected communities and wider stakeholders of the details of the Grievance Mechanism. This will include information about where people can go and who they can talk to if they have a grievance, who can register a grievance and process timelines. This information should be widely and regularly publicized, throughout the duration of any project, through posters at key locations , advertisements in local papers I radio and verbally by Septa employees. Septa will provide the information in a format and using languages (including local languages) that are readily understandable by the local population and/or orally in areas where literacy levels are low.

3) All complaints submitted or communicated to Septa employees or contractors should be addressed in a timely and appropriate manner. This includes factual, perceived or misrepresented grievances. Unreported grievances are a missed opportunity to build trust, improve community relations and identify emerging issues.

4) A grievance can be submitted by any affected party. This includes communities directly and indirectly affected by Septa Energy's projects, civil society, local and traditional authorities, local or national government, small business owners, associations, medical and educational practitioners, NGOs and international third parties.

5) The mechanism should be culturally appropriate, clear and easy to follow with defined timelines for key process milestones. The mechanism should be sensitive to local preferences towards conflict resolution, negotiation and

cooperation taking into account understandings of authority, social status and rank, community relationships and attitudes towards third parties.

6) The Grievance Mechanism should be easy to access for communities. Septa Energy will make available a range of measures for submitting complaints including face-to-face meetings, by post, email or left in suggestion boxes, online submissions and by telephone. A Grievance Form for external use is provided in Annex 3.

7) The Grievance Mechanism should be readily accessible to all stakeholders and communities including vulnerable groups such as women and youth at no cost to them. Assistance should be provided to those who face barriers to participation due to language, literacy, awareness, time, distance. finance or fear of reprisal.

8) The Grievance Mechanism should not impede access to judicial or administrative remedies or seek to replace these. The mechanism should never result in any kind of retribution.

9) Septa Energy will facilitate a variety of grievance resolution approaches according to individual and cultural preferences. This includes informal processes or more formal approaches involving a third party mediator or legal redress. Traditional or customary practices should be considered and incorporated. This may include inviting respected community members to act as observers, witnesses or testifiers to give legitimacy to the resolution process. Respected community members should also be solicited for advice on settling differences in a manner that complies with and respects community norms.

10) Septa Energy will provide regular feedback to relevant stakeholders to demonstrate how the Grievance Mechanism is working, clarify its purpose, manage expectations and encourage more people to use the system. Examples can be given of how cases were managed and resolved and how outcomes changed Septa policies or procedures to inspire trust and confidence that the system works.

11) Septa will maintain a record of all grievances in a central Grievance Database system. Grievance settlements will be monitored to ensure consistency. Analysis of this record might highlight grievance or conflict trends or emerging issues, allowing mitigation measures to be put in place to avoid risk to operations. If a common issue is identified, structural changes at company level might prevent the grievance from recurring rather than resolving each case on an individual basis. Such mitigation should be included in the Project Environmental and Social Management System.

12) The Grievance Mechanism will be regularly evaluated by Septa to improve its effectiveness. The evaluation will take into consideration general awareness of the Grievance Mechanism process, level of use, who uses it, type of issues addressed, ability of process to resolve issues promptly and constructively; outcomes (changes to company operations, management systems and community benefits) and overall ability to achieve stated goals and objectives. Stakeholder feedback should be gathered and incorporated into the evaluation process where appropriate.

The Grievance Process

The following steps outline the process that will be followed to resolve a grievance. This process is also presented in a diagram in Annex 1. A check list of documents and resources required to complete the Grievance Process is found in Annex 8.

1. Setting up channels and methods available for registering a complaint

a. Channels: Septa Energy will establish multiple channels to collect and forward grievances from the community. A network of community representatives (community leaders, government officials, community organisations, company environmental and operational employees, community liaison officers), including at least one member that is independent of Septa Energy, should be identified to receive community's concerns and deliver them to the CLO for further action.

All Septa project and contractor staff should also be fully aware of the Grievance Mechanism process so that they know how to receive a complaint themselves and pass it on to the CLO, or else instruct community members about how they can access the Grievance Mechanism in another way.

b. Methods: Septa will set up multiple culturally appropriate methods for registering complaints including self-identified, confidential and anonymous procedures. This will include a postal, email and website address, a drop-box at all sites and in key community locations, a toll-free telephone line and hosting of face-to-face individual or group meetings. The Community Liaison Officer is responsible for receiving all complaints and logging them into the Septa Grievance Database.

The details of any Grievance Forms received (see Annex 3) should be transferred to the Grievance Log (see Annex 4) that will be used internally.

2. Logging Grievances

Septa Energy will log, document and track all grievances received within the secure Septa Grievance Database system. Grievances should be assigned a case number and records of communication/consultation should all be attached with the relevant entry. The database should be monitored regularly for recurring grievances so that appropriate mitigation can be developed.

As a minimum the following information shall be recorded:

Septa Energy QHSSE Manual

• Contact information- name, tel, address etc

• Date of complaint

• Details of complaint

• History of other complaints I queries I questions (if known);

• Prioritisation and categorisation based on Significance Criteria provided in Annex 2

• Outcome of the actions implemented.

An example of a Grievance Log form is provided in Annex 4.

3. Acknowledging receipt of grievance

Septa Energy shall acknowledge receipt of any grievance within 7 days from the date it was submitted and shall inform the complainant about the timeframe in which a response can be expected. A grievance receipt form should be signed and a copy provided to the complainant. An example of a grievance receipt form is provided in Annex 5.

4. Investigating eligibility and severity of grievance:

Before selecting the correct procedure for resolving a grievance. the eligibility and severity of the grievance must be determimxJ. This will influence how the grievance wii! be handled, who wil//)e involved and how lonq the resolution process is likely to take.

Eligible griovances include ail those that are directly or indirectly related to Septa Enerqy's projects and that fa!! within the scope of the Grievance Mechanism as outlined above.

fneiigibie Complaints may include those that are clearly not related to any of .Seven Energy or its contractors· projects. whose issues fall outside the scope of the Grievance Mechanism procedure or where other Septa Energy or community procedures woul(} be n;or(ct appropriate lo Bddress the grievance.

The complainant should be engaged in conversation in an effort to truly understand the grievance fleforo it is cfismissed Even if a cornpfaint is invalid and unlinked to project operations, an investigation may uncover unck:rfying misperceptions and concerns w!tf1 the project. Taking seriously ali complaints submitted can increase trust in Septa ami tile project,

If the grievance is considtW:Jd e!igitJie, it musl be classified according to th('J severity anct urgency of the grievc.mce. This includes the risk it poses to both tile community a(l(1 to Septa Energy's operations and reputation Refer to the Grievance Ciassification Matrix provided in Annex 2.

Septa Energy will investigate fully all grievances submitted, involving other departments, contractors and senior management as required in this process to fully understand the circumstances that led to the Grievance. Septa Energy will aim to

~~£.~ E~~~~-·--·-----·~------------QHSSE Manual

resolve any grievances within 30 days from the date that it was received. This timeframe can be extended to 60 for Level 4 and Level 5 Grievances (see below}, if required.

The following steps should be performed in a timely manner to avoid delaying resolution of a grievance:

1) Assign the grievance to a CLO to manage the grievance directly and conduct the investigation into the grievance.

2) Obtain as much information as possible from the person who received the complaint, as well as from the complainant to gain a first·hand understanding of the grievance.

3) Undertake a site visit to clarify the parties and issues involved. Gather the views of other stakeholders including Septa employees and identify initial options for settlement that parties have considered.

4) Determine whether the grievance is eligible (See box above).

5) If the grievance is deemed ineligible it can be rejected however a full explanation as to the reasons for this must be given to the complainant and recorded in the Grievance Log.

6) If the grievance is eligible, determine its severity level using the significance criteria in Annex 2. This will help to determine whether the grievance can be resolved immediately or requires further investigation and whether senior management will need to be informed of the grievance.

7) If the grievance concerns physical damage, (e.g. crop, house, community asset) take a photograph and GPS coordinate of the damage.

8) Inform the complainant of the expected timeframe for resolution of the grievance

9) Enter the findings of the investigation in the Grievance Log.

5. Grievance Settlement and Resolution Approach:

A guide to grievance settlement measures is provided in table 2 below. It is important to note, however, that most grievances should be dealt with on a case by case basis. Face-to-face discussions with complainants and community members, that seek to jointly identify and select measures for grievance settlement, will increase ownership of solutions and help to mitigate perceptions that resolutions unfairly benefit Septa Energy.

Compensation rates will be set by the Septa Wide Community Liaison Officer. These may change periodically depending on market prices thus should be regularly checked and updated by project CLOs. Compensation payments can often cause conflict or disputes thus it is important that compensation rates are applied consistently and fairly across Septa Energy operations.

Community: Grievance Mechanism (SOP-xnooq -~;~~ised: --Authorised by:

Below are four basic resolution approaches that can be offered. Complainants should have influence over the approach selected:

• Septa Energy proposes a solution

This approach can be used for straightforward issues with obvious solutions, which Septa Energy can resolve alone to the satisfaction of the complainant. The decision to accept or reject it should be taken together thus sharing decision-making authority.

The resolution proposal should be respectful and considered, including rationale for the decision and any data used in reaching it. The case presented by the complainant during the decision making process should be acknowledged. The solution should be delivered in writing and where appropriate by the CLO to explain the response in person.

If the complainant is not happy with the proposed solution. a joint decision process (described below) should be offered. If this too is rejected, the grievance can be referred to a third party mediator or for legal arbitration.

• Septa Energy and the complainant decide together

Joint decision making approaches are the most likely to achieve a positive outcome and should be the core approach used in the grievance mechanism process.

This approach should be used for more complex cases involving a variety of stakeholders. It should also be used in situations where it is important to preserve an on-going relationship and where face-to-face engagement is valued.

Under this approach decision-making is shared and all parties engage in a join problem solving approach to resolve the grievance. The process can be informal, on4he-spot or can take a formal approach involving a mediator to help the parties reach an agreement. Good listening, information sharing, joint fact-finding, dialogue and negotiation are all essential features of this approach.

• Septa Energy and the complainant defer to a third party to decide such as village mediation committee

This approach should be used if a joint approach has been rejected or has failed to reach a voluntary settlement. It is also appropriate where there are disputes about facts or data. The third party may be a trusted individual or group In the community, an international or local NGO or a technical expert. They control the process and investigation of the grievance and make recommendations for settlement.

This approach involves joint submission of the grievance and both parties' views to the third party, who may also undertake a fact-finding process to allow an independent assessment of the grievance and the relevant Septa Energy practices. An agreement should be made with the complainant at the outset of this process about how to proceed once the results of the investigation are shared, and whether to treat recommendations as binding.

• Legal Recourse I Arbitration

This is a more formal rights based approach that should only be taken if all other approaches have failed or when there are serious conflicts about facts and data. The final decision will be taken by the courts based on compliance with laws, policies, standards, rules, regulations, procedures, past agreements or common practice.

6. Communicating Response

If the grievance was not resolved immediately, once further investigation has taken place, a meeting should be held with the CLO, relevant Septa Energy manager and complainant or third party mediator. Next steps and any proposed solutions should be discussed during this meeting.

Once all parties are satisfied that the grievance has been resolved, a note of how and when it was resolved should be recorded in the Grievance Log and either a Grievance Closure Form or a Compensation Receipt Form should be signed by the complainant. Examples of a Grievance Closure Form and a Compensation Receipt Form are provided in Annex 6.

The following grievance responses might be discussed:

• No cash or in-kind compensation required

When responding to grievances relating to, for example, the unfair application of Septa Energy recruitment procedures or lack of project information, Septa will provide a verbal explanation or written documentation to the complainant. Once the complainant is satisfied that their grievance has been addressed, a Grievance Closure Form should be signed and filed with the relevant Grievance Log.

• Cash or in-kind compensation is required

If the response is a settlement offer and the offer is accepted then the case can be closed. Arrangements for payment or provision of compensation should be agreed and once they have been received by the complainant the case is closed and a Compensation Receipt Form should be signed and filed with the relevant Grievance Log.

• Complainant is not satisfied with proposed response

If the complainant is not satisfied with the proposed response to their grievance, a third party mediator can be brought into the discussion. If the resolution proposed by the external mediator is mutually acceptable the case should proceed to closure based on the agreed action.

• Complainant is not satisfied with the solution provided by third party mediator

If the complainant is not satisfied with the settlement proposed by the third party mediator they will have access to an arbitration process. The case should be forwarded by the CLO to Septa Energy's legal department and the CLO should remain in the process as mediator until the case is closed. A note of each step and the final settlement should be recorded in the Grievance Log. ·

7. Follow-up

Two or three weeks after the grievance has been resolved the CLO should visit the complainant to ensure they are satisfied that the matter has been resolved and should record this visit with any relevant comments in the Grievance Log.

G. Auditing

The grievance mechanism shall be subject to monitoring and evaluation internally every 6 months for the first two years and annually thereafter to ensure its effectiveness. The following Key Performance Indicators should be monitored:

Grievance Mechanism

This is a community relation grievance procedure and guideline that outlines the approach to accepting, accessing, resolving and monitoring grievances from those affected by Septa activities including the contactor's activities working for Septa.

A grievance or complaint is an issue, concern, problem or claim (perceived or actual) that an individual or community, group of persons has related to Septa Energy and its contractors' operations and activities. A more detailed document is contained in the SOP for grievance Mechanism.

Why handle Grievance

SENL recognize the fact that despite the best endeavours between parties;

• Disputes and conflicts may arise from time to time and need to be handled in a manner to bring prompt resolution.

• Minor concerns as well as serious or long -term issues may arise that needs to be systematically resolved to prevent them from escalating into major issues of risk to operations

• Reputation/image of company both Nationally and Internationally needs to be protected at all times

• Building cordial relationship and trust with stakeholders is of importance to our operation

SCOPE/COVERAGE

This procedure and guideline is to cover community complaints and grievances, perceived or actual at all existing and new SENL facilities, assets and properties owned in full or part and or operated by the company in order to manage the company's risk and relations with stakeholders throughout the project life cycle

APPLICATION:

The grievance mechanism is to provide guidance to employees of SENL and contractors on how to receive, register, assess and resolve community complaint or grievances from Septa operation.

OBJECTIVE

This process is aim at achieving the followings:

• Provide a predictable, transparent and credible process to all parties for resolving grievances to have outcomes that are seen as fair, effective and lasting

• Build trust and confidence as an integral part of the broader community relations activities and function

• Provide enabling environment for a more pragmatic identification of emerging issues and their trend thus facilitating corrective action and pre-emptive engagement.

The schematic in Figure 1 below is a guide to achieving the set objectives of grievance identification, registration, assessing and resolving. It is important to state that keeping to the times specified for activities is quite important in achieving the goals and objectives.

ROLE, RESPONSIBILITIES AND RESOURCES

The grievance mechanism shall be the responsibility of the Community Relations Manager, while the Community Liaison Officers (CLOs), Community Relations Officers (CROs) and the RAP project Officer based locally at each facility, asset, project or area; play the active role in ensuring its companywide consistent application and community commitment to and understanding of its implementation and operation. For effective grievance Management, all departments in Septa and the Board of Directors shall play the roles identified for them below.

All SENL department and contractors have a role in the grievance mechanism management to receive and acknowledge any issue, concern, complain or grievance from the community verbally or in writing, which should be recorded and reported to community relations team in a recorded/written form in compliance with the grievance mechanism procedure within the time specified. Please note that, there shall be involvement of individuals from such departments originating the grievance in the investigation of the grievance as required depending on the nature and severity of the grievance.

The Board of Directors/CEO has the role of ensuring that the grievance management process/procedure is applicable all through Septa Energy and contractor departments and levels. The board has the role to accede to, and apply all necessary controls to minimize risk that could result in community grievance and also contribute to resolutions by signing off on any grievance which have international repercussions.

The board also has the role of providing a dedicated budget for management of grievances and addressing grievances through in -kind or financial compensation as and when due and found so to be.

As a requirement, there will be an auditable system for the receipt, recording and tracking of the process-a grievance log data base in place generated from the attached forms in appendix Al to Fl.

Core values and Guiding Principle

The following core values shall be upheld by SENL during implementation and operation of the system for effectiveness and good results.

• Commitment to fairness in both process and outcomes;

• Freedom from reprisal for all involved parties - within Septa and in the community;

• Dedication to building broad internal support for the grievance mechanism across project lines;

• Mainstreaming responsibility for addressing grievances throughout the project, rather than isolating it within a single department; and

• Willingness by senior management to visibly and sincerely champion the grievance system.

Principles: The following principles guide the SENL Grievance Mechanism procedure:

1) This grievance mechanism complements and reinforces Septa's wider stakeholder engagement activities. Proactive engagement is essential for good relations with communities and stakeholders. The Grievance Mechanism should not be implemented in isolation of stakeholder engagement.

2) Septa Energy will proactively inform affected communities and wider stakeholders of the details of the Grievance Mechanism. This will include information about where people can go and who they can talk to if they have a grievance, who can register a grievance and process timelines. This information should be widely and regularly publicized, throughout the duration of any project, t hrough posters at key locations (e.g. outside a village town hall), advertisements in local papers I radio and verbally by Septa employees. Septa will provide the information in a format and using languages (including local languages) that are readily understandable by the local population and/or orally in areas where literacy levels are low during routine stakeholder engagement.

3) All complaints submitted or communicated to Septa employees or contractors should be addressed in a timely and appropriate manner. This includes factual, perceived or misrepresented grievances. Unreported grievances are a missed opportunity to build trust, improve community relations and identify emerging issues.

4) A grievance can be submitted by any affected party. This includes communities directly and indirectly affected by Septa Energy's projects, civil society, local and traditional authorities, local or national government, small business owners, associations, medical and educational practitioners, NGOs and international third parties.

5) The mechanism is expected to be culturally appropriate, clear and easy to follow with defined timelines for key process milestones. The mechanism should be sensitive to local preferences towards conflict resolution, negotiation and cooperation taking into account understandings of authority, social status and rank, community relationships and attitudes towards third parties.

6) The Grievance Mechanism should be easy to access for communities. Septa Energy will make available a range of measures for submitting complaints including face-toface meetings, by post, email or left in suggestion boxes, on-line submissions and by telephone. A Grievance Form for external use is provided in appendix A 1.

7) The Grievance Mechanism is expected to be readily accessible to all stakeholders and communities including vulnerable groups such as women and youth at no cost to them.

8) The Grievance Mechanism is not expected to impede access to judicial or administrative remedies or seek to replace these. The mechanism should never result in any kind of retribution.

9) Septa Energy will facilitate a variety of grievance resolution approaches according to individual and cultural preferences. This includes informal processes or more formal

approaches involving a third party mediator or legal redress. Traditional or customary practices which include inviting respected community members to act as observers, witnesses or testifiers to give legitimacy to the resolution process shall be used in most cases. Respected community members should also be solicited for advice on settling differences in a manner that complies with and respects community norms and company policy.

10) Septa Energy will provide regular feedback to relevant stakeholders to demonstrate how the Grievance Mechanism is working, clarify its purpose, manage expectations and encourage more people to use the system. Examples can be given of how cases were managed and resolved and how outcomes changed Septa policies or procedures to inspire trust and confidence that the system works.

11) Septa will maintain a record of all grievances in a central Grievance Database system. Grievance resolution settlements will be monitored to ensure consistency. Analysis of this record might highlight grievance or conflict trends or emerging issues, allowing mitigation measures to be put in place to avoid risk to operations. If a common issue is identified, structural changes at company level might prevent the grievance from recurring rather than resolving each case on an individual basis. Such mitigation should be included in the Project Environmental and Social Management System.

12) The Grievance Mechanism will be regularly evaluated by Septa to improve its effectiveness. The evaluation will take into consideration general awareness of the Grievance Mechanism process, level of use, who uses it, type of issues addressed, ability of process to resolve issues promptly and constructively; outcomes (changes to company operations, management systems and community benefits) and overall ability to achieve stated goals and objectives. Stakeholder feedback should be gathered and incorporated into the evaluation process where appropriate.

Channels: The channels to collect and forward grievances from the community shall be through a network of community representatives (community leaders, government officials, community Organizations, company environmental, Safety and operational employees, community liaison officers), including at least one member that is independent of Septa Energy such MOU implementation committee members, should be identified to receive community's concerns and deliver them to the CLO/CRO for further action.

All Septa project and contractor staff should also be fully aware of the Grievance Mechanism process so that they know how to receive a complaint themselves and pass it on to the CLO, and also instruct community members about how they can access and channel their Grievances following the procedure.

Methods: Several methods that are culturally appropriate will be used for registering complaints including self-identified, confidential and anonymous procedures. This will include a postal, email and website address, a drop-box at all sites and in key community locations, a toll-free telephone line and hosting of face-to-face individual or group meetings. The Community Liaison Officer is responsible for receiving all complaints and logging them into the Septa Grievance Database for transfer into the grievance log.

Annex 4A : Environmental Sensitivity Mapping Description

The current study is based on a gas pipeline to be constructed from Uquo to Usung near Oron. The pipeline will pass through three vegetation zones mainly of lowland areas which are made up of fresh water swamp forest, farmlands /fallow areas as well as fresh water swamps mixed with patches of mangrove especially close to Calabar River. The swamp forests along the pipeline route are of little agricultural importance because the soils are saturated with water, making only water loving plants to survive/thrive.

Indeed this is the most sensitive part of the pipeline route and was encountered at the beginning of the pipeline ROW. The area is only partially degraded and serves as habitat which harbours various terrestrial and swamp organisms etc. As one moves along the pipeline route the land becomes drier and hence is cultivated for various tree crops. Within this zone are the oil palm and other plantation crops such as plantain/ citrus etc. This zone is dominated by bush fallows, farmlands, plantations and secondary lowland forest. The area is of medium agricultural activities with mainly tree crops in plantation.

This is followed by a mangrove zone interspersed by scanty freshwater plants which occur at the end of the pipeline ROW. The area is designated as mangrove forest in the E5I report. Mangrove forest is dense along the Calabar River; and on the banks of the streams flowing into the Calabar River. A number of mangrove species where encountered in the mangrove habitat and these are documented in the E5I and EIA reports. The mangrove soil fauna was made up mainly of decapod crustaceans and gastropod molluscs. These include the fiddler crab, marsh crab (Seserma huzardi), purple mangrove crab (Goniopsis pelii) and the lagoon land crab (Cardiosoma armatum). Others include the periwinkles, whelk and oyster (Crassostrea gazar).

As recorded in the EIA report, the chloride content of the soils, ranged from 17.67 to 353.23mg/kg and these levels were higher than the control samples (7.09-79.98 mg/kg) indicating estuarine conditions. Thus the presence of plant species such as Rhizophora, and mangrove associates such as Acrostichum aureum (mangrove fern), Paspalum vaginatum (mangrove grass), Machaerium lunatus and Dalbergia ecastaphyllum gives credence to the observed mangrove habitat among the major vegetation types reported in the E5I report.

The presence of mangrove swamp at the water -side at Usung close to the pipeline proposed tie - in - point was recorded along the pipeline ROW (5530/VEG 30); Therefore the end of the pipeline and the tie-inpoint lie within the mangrove habitat.

Revision 1 Page 1

The swamp forest at the beginning of the pipeline and mangrove forest recorded at the end of pipeline ROW have similar soil texture in terms of their wetness and the mechanism of crossing these swamps shall be similar.

Wildlife Report on Uquo-Oron gas pipeline project for SEPTA.

Methodology

The Uquo-Oron gas pipeline EIA studies were carried out during two seasons of

sampling, rainy and dry season. The dry season sampling was carried out from

March 7 - 12, 2011 while the rainy season sampling took place between 12 and 17

July 2011. Sampling took place along the pipeline route from Oron to Uquo CPF in

Akwa Ibom State, Nigeria. Assessment of the biodiversity of the area was carried

out through field observation, interviews with local hunters, and reference to

specialist institutions and experts. The studies centered on a number of intensive

study locations along the pipeline route in which the biological diversity, soils,

topography, major vegetation communities and climatic conditions of the proposed

project area was studied. At each study location, the invertebrates and vertebrates

population (including arthropods, birds and mammals) were observed in their

habitat. This was corroborated with data collected from interviews with hunters and

trappers from the area. The communities studied include Oron, Esit Eket, Akwata,

Urua Okot, Akpautong, amongst others.

Specimens sighted in the field were identified using taxonomic guides and voucher

specimens in the Zoology Museum, University of Benin. Identification and

nomenclature are based on the field guide of Birds of Nigeria and West Africa

(Eigood, eta/. 1994; Serle et al., 1977), Mammals of Nigeria (Happold, 1987).

Results

The terrestrial invertebrates were dominated by arthropods, including insects and

spiders and molluscs. The terrestrial invertebrates were mainly dominated by

arthropods including insects and spiders, and land molluscs. The mangrove soil

fauna at Oron, Uqua CPF, and part of Esit Eket were made up of mainly decapod

crustaceans and gastropod molluscs. These include the fiddler crab, marsh crab

(Seserma huzardi), purple mangrove crab (Goniopsis pelii) and the lagoon land

crab (Cardiosoma armatum). The mangrove molluscs were mainly periwinkles,

whelk and oyster (Crassostrea gazar).

Most of the species recorded during the survey were common and may not be

threatened by the proposed project activity, although some species are of unclear

conservation status or have not been categorized by IUCN. Other species fall under

the category of "Least Concern" in the IUCN category.

Tables 1-3 show a checklist of some vertebrate species observed or reported from

the area of study with their conservation status. The amphibians, mainly frogs and

toads were all common and abundant during the rainy season. The reptiles (Table

1) recorded include lizards, snakes, and tortoises. Crocodiles reported include the

short snouted crocodile, and the long snouted crocodile. The Nile crocodile was not

recorded in the region and maybe locally extinct. Lizards were common but the

population of the monitor lizard, Varanus niloticus, is gradually declining because of

hunting pressure. More individuals of the monitor lizard were recorded during the

rainy season than the dry season. Skinks were abundant in the region, but more

individuals were recorded in the dry season than in the rainy season. The crocodiles

and the Royal Python were the vulnerable reptilian species found in the area. Other

reptilian species are either not threatened or vulnerable depending on the rate of

hunting or destruction of their habitat.

The birds' species found include those characteristic of disturbed habitats,

farmlands and gardens along the Oron Uquo CPF, Esit Eket, and other communities

along the pipeline route. Table 2 gives a list of avifauna found in the area of study.

They include finches, bulbuls, Crows, Sunbirds, Hornbills, Senegal Coucal, Hooded

Vulture, Black Kite and Tambourine Dove. Birds of prey including hawks, kites,

harriers, and crows dominated the fauna in Oron especially along the pipeline route

near the Uquo central processing facility (CPF). The birds were more abundant in

the dry season than in the rainy season. We recorded over 60 individuals of hawks

and crows at a particular site near the Uquo CPF during the dry season sampling.

The mammals were dominated by rodents mainly rats, grasscutter, squirrels, and

porcupines. These species are neither threatened nor endangered. Other

mammalian species reported include primates (monkeys), carnivores (cats),

artiodactyla (antelopes) and pangolins. Apart from the primates which are

vulnerable, non of the mammalian species recorded in the region was threatened

by the project development. This was confirmed using the IUCN Redlist of

endangered species' list (2012). Even though we observed a large population of

Mona Monkeys at Esit Eket and Urua Orok during the rainy season, these species

were not threatened. However, continued destruction of the forest may lead to

their extirpation and result in local extinction.

PROCEDURES

SOP 916- Hydro-testing Revised: Apr 2010 Authorised by: SA

All testing equipment shall be supplied by Septa Energy. The Foreman shall be responsible for all test preparations, including fabrication of test ends, test manifolds, piping, pipe filling, and draining. The location for filling, testing, and draining the pipeline shall be mutually agreed between the Project Engineer and Septa Energy.

As required by Septa Energy, a water sample shall be tested by an approved laboratory and presented to the Construction Superintendent for approval prior to filling. Based upon the water sample and project specifications, corrosion inhibitors and biocides and any other specified inhibitors shall be added to the water, as required, during filling.

Under normal circumstances, the Company shall be responsible for providing permits for obtaining, using, and disposing of water for cleaning and testing purposes. Septa Energy shall submit details of the equipment and instruments to be used and certification to be provided. Instrumentation and pressure testing equipment shall be calibrated prior to the hydrostatic test by a qualified technician or an approved, independent company.

The appropriate pressure and temperature gauges, recorders, dead weight tester, and valves specified shall be connected to the installed pipeline in preparation for the hydrostatic test. Test measuring equipment shall be calibrated. The connections and the test assembly shall be checked by the Foreman for conformity to this procedure and to ensure that all safety precautions have been taken.

All valves, if installed, shall be in the open position during the hydro-test. Check valves shall be either removed or blocked in the open position during test.

The installed pipeline shall be hydrostatically tested to the specific test pressure (STP), as either one unit or a series of sections, unless specified otherwise by the engineer. When specified, each test procedure shall contain test plans or sketches identifying the piping sections to be tested, the pipe test legend indicating the test pressure, the test medium, and any other pertinent information. In the event of a conflict between this procedure and the detailed specific procedures, the test procedure shall prevail.

2. Testing


Flushing and cleaning is achieved by flushing until debris is removed or by running pigs through the pipeline, as specified in SOP 915. If pigs are used, water is continuously pumped into the pipeline at the launch area until the pigs are received at the catch area. As the water is pumped into the pipeline, air is bled off at the catching area.

Testing of the installed piperine shall be tested and pressurised to the STP.

After filling, the pipeline shall be stabilised. The stabilization period shall be as specified in the project specification. After the stabilization period, the test is started. During the testing of the pipeline, QC will check for pressure drops. Should a leak occur, the test pressure is reduced to 0 psig, repairs other than welding are completed, and the pipeline is subsequently re-pressurised and re-tested.

Test pressures and temperatures shall be recorded on the chart throughout the testing period. Upon satisfactory completion of the test, the results shall be recorded on Form QR-022.

3. Hydrostatic Test Acceptance Criteria

To satisfy the testing requirements, the pressure in the line must be maintained without pressure variations that cannot be accounted for by changes in temperature. Since precise verification is difficult, a tolerance of ± 0.2% of the specific test pressure, after temperature corrections, is accepted. The test shall be accepted if all pressure containing components In the test section maintain their integrity and no leaks are found.

Any reduction in pressure outside the limits specified or variation in temperature that cannot be accounted for shall result in a test failure. Possible causes for failure, such as loose bolts and/or fittings, leaking gaskets, test pump failure, air entrapment, or weld failure, shall be located and rectified. After rectification work is complete, the pipeline section shall be refilled with water and the procedure in clause 6.2 repeated until such time as the STP can be satisfactorily maintained.

After acceptance of the test, the line Is gradually de-pressurised. Further dewatering is stopped and the line is left filled with the water used for testing until such time as the Company is ready to put the line into service.

4. Pipeline Commissioning

Following acceptance or approval of the hydro-test, the test liquid shall be displaced from the pipeline with a multiple cup or bi-directional disc pig propelled by compressed air. Free draining of the line during de-watering may be allowed.

When required, drying runs are made to remove all remaining water from the line. After the line is free of water, abrasive or brush pigs are run with dry compressed air to remove any rust or mill scale from the pipe wall prior to commissioning, in accordance with Clean and Gauge {SOP 915).

Following satisfactory testing, temporary test heads, blind flanges, instruments, and other test equipment are removed and returned to the Septa Energy yard. All test records and record charts shall be signed by Septa Energy and included in the as-built documentation package.

On completion of the above, the pipeline is released for final installation and tie-in.

5. Safety and Environmental Protection

All employees and contractors engaged in hydro-testing operations must comply with the Septa Energy SOPs regarding health, safety, and protection of the environment. Where appropriate, risk assessments should be carried out to ensure that all the hazards associated with the activities:

• Are identified and assessed, and

• Have controls put in place to reduce risk to people (including local communities), environment, assets, and reputation to a level that is as low as is reasonably practicable.

In addition, a bathymetric survey will be carried out in accordance with the Pipeline Survey Procedure (SOP 901) to plot the existing profile of the riverbed along the pipeline route in order to establish a final pipe profile.

3. Dredging


A bucket dredge will be utilised for dredging smaller and shallower creek crossings. The bucket dredge will also be used to excavate the slot in the banks of the river/creek. All dredging will be carried out in accordance with procedure.

4. Welding

The welding of the pipe strings will be done on the bank of the river. On completion, they will be pushed into a floatation ditch of sufficient length to cover the complete width of the river crossing pipe string. As the pipeline is pushed into the ditch utilising rollers, floaters will be fixed on the top of the pipe at determined intervals to enable the river crossing section to float in the ditch. Welding and radiography will be carried out in accordance with the welding and NDT procedures. Welding and cutting field joint coating will be carried out in accordance with the appropriate procedures.

5. River/Creek Crossing Installation


Prior to pulling operations, the following preparations shall be performed:

• Calculations to determine the level of buoyancy to be applied to the pipe string in order to limit the maximum pulling load and determine winch selection;

• Functional testing of winch;

• Final survey of bottom profile to be performed after completion of dredging. Client to review and, if satisfactory, approve the final survey within 24 hours of receipt;

• Lay pull cable across the river;

• Positioning of winches;

• Bury pull anchors; and

• Hydro-testing of the river crossing section, see Hydro-testing {SOP 916).

To commence the pulling operations, the pull winches will be positioned at the bank and adjacent to the pipe-pulling head. The wire rope will be connected to the pipeline through the pulling head. The pulling wire rope will be laid in the excavated trench in the river bottom. When the winches start pulling the river crossing section, the river crossing supervisor will control the speed at which the section is pulled

When the pipe reaches the opposite bank, it will be located in the pulling slot on the pipe centreline. The anchors will then be placed and buried on the bank of the river. Anchor winches will be used to tension the anchor lines and to set the anchors.

The pipe will be pulled along the river bottom by the winches located on the pulling barge. The pipe will be pulled continuously until the pulling head reaches the pulling end.

During pulling operations, the required amount of floaters will be removed from the pipe sections at the edge of the bank of the river, which will enable the pipeline to sink to the bottom of the trench with the designed buoyancy, due to the presence of the remaining floaters, for the pipe string to be installed without excessive pull loads.

After the completion of pulling operations, a bathymetric survey is carried out to confirm the proper positioning of the pipeline within the trench.

The installed pipeline will be cleaned and gauged in accordance with SOP 915 and hydrostatically tested in accordance with SOP 916. Prior to backfilling and acceptance of the hydro-test, the floaters will be removed using a rip cable. On successful completion of the test and acceptance of the gauging plate, backfilling will commence in accordance with SOP 906.

Final survey of the backfilled river/creek crossing will be carried out in accordance with Pipeline Survey {SOP 901) to confirm restoration of original profile.

1.0 Introduction.

Section 15(1) of the Oil Pipelines Ordinance (CAP) 145 prohibits the holder of an

Oil Pipeline License {OPL) to enter upon, take possession of or use any of the

following lands unless the occupiers or persons in charge thereof have given their

assent:

(a) Any land occupied by a burial ground or cemetery,

(b) Any land containing any grave, grotto, and trees or things held to be sacred or the object of veneration/

(c) Any cultivated land.

Septa Energy as part of site/route selection avoids cultural heritage sites/routes

which may contain archaeological structures. This is with a view to minimizing

adverse impacts to cultural heritage. This procedure outlines the process steps to

be followed when a tangible cultural heritage is encountered unexpectedly during

project construction and operation.

1.1 Objectives.

The main objective of this document is to ensure that there is a procedure in place

which will be applied in the event that a cultural heritage/ archeological structure

are discovered during construction or operation of any Septa Energy facility.

1.2 Chance Find Procedu're

The following procedure will be is executed in the event that Archaeological

material 1 graves or other artifacts are discovered in the course of right-of-way

clearing, ditching or borrow pit operation.

i. All construction activity in the vicinity of the find/feature/site will cease

immediately, and the Site Health Safety and Environmental (HSE) Officer

and the Project Manager will be informed of the find.

ii. The HSE officer or Project Manager will delineate the discovered find/

feature/ site with tape or other marking material to prevent unauthorized

persons from entering, record the find location and ensure that all

materials are left in place.

iii. Site Security personnel will secure the area to prevent any damage or loss

of removable objects.

iv. The Project Manager will inform the Septa Energy, which will in turn inform

the Chief Artefacts Officer in the Ministry of Culture/ Museum and

Tourism. He/she will in turn report find to the Curator of the National

Museum and request a site visit by a qualified archaeologist.

v. Work at the location will not resume until the Archaeologist has

determined what course of action to take:

- continue work because the find has no cultural or archaeological value 1

- continue work after the find has been relocated or removed to safe

storage under the guidance of the Archaeologist,

-or divert the works around the site if the find needs to be preserved in

situ.

The contractor's equipment operators and supervisory personnel will be trained in

recognizing items that could be of cultural significance. The chance finds procedure

will be explained to operators, supervisors, HSE Officer, project engineer and other

relevant staff and will be posted at appropriate locations.
