The primary objective of an Environmental and Social Management Plan (ESMP) is to safeguard the

environment, site staff and the local population from site activity that may cause harm or nuisance. The

management plan, which also covers monitoring, is the basis of the environmental and social protection

measures to be implemented by PGE and its contractors (EPC contractors for the power plant and

Steamfield Above Ground System and drilling contractors). The implementation of the ESMP ensures

EHS performance is in accordance with international standards (including the relevant World Bank

operational policies and World Bank Group EHS guidelines) and best practice.

Where relevant this volume consolidates the mitigation requirements identified in the UKL/UPL reports for

the Project and those identified as part of the international ESIA process (presented in Volume II of the

ESIA).

The environmental management requirements presented in this document have been based on the

findings of the following:

� Site visit and data collected by MML’s team to the Project site in March and June 2010 and January

2011;

� This international ESIA documentation prepared by MML (draft in 2010, revised 2011); and

� UKL/UPL reports for the Project.

The mitigation measures identified within this document will be implemented within a formal EMS aligned

to ISO 14001:2004, the international standard for EMS, or equivalent. Guidance on requirements for EMS

for power plants is also discussed and addresses:

� Organisation and responsibilities;

� Training and awareness;

� Emergency procedures and response;

� Record keeping; and

� Performance monitoring, reporting and auditing.

Responsibilities for implementation are outlined in the ESMP and fall to either PGE or the various

contractors including the power plant EPC Contractor, the Steamfield Above Ground System (SAGS) EPC

Contractor and the drilling contractors. Where responsibilities fall to the contractors these should be

implemented via the contractor’s own EMS (preferably accredited to ISO 14001:2004 or equivalent).

In addition to this ESMP, this volume provides corresponding arrangements such as framework sub-

management plans.

1. Introduction


2


2.1 Overview

The key parties and their primary roles in implementing the ESMP as elaborated with this Volume IV of the

ESIA for the Project are summarised as follows:

� PGE – responsible for overseeing compliance with environmental policy and monitoring compliance of

the Project, and ensure compliance with the obligations set out in the ESMP on a day to day basis

during the construction phase and operation phase; and

� EPC Contractors (power plant and SAGS) - responsible for implementing the site specific construction

ESMP via their own environmental management system to be approved by PGE; and

� Drilling Contractors – responsible for following and complying with construction ESMP requirements set

out by PGE.

2.2 PGE EHS Management

2.2.1 Environmental Health and Safety Policy and Commitment

Pertamina’s Corporate Centre for Environmental Protection, Occupational Health and Safety (known as

HSE Corporate or Kesehatan Keselamatan Kerja dan Lindung Lingkungan (from here on referred to as

K3LL) has the task to carry out corporate studies and development efforts in the field of Environmental

Protection and Occupational Health and Safety across the Pertamina businesses (including PGE).

Progress in various aspects of this task has been achieved by K3LL since its establishment, in particular in

obtaining Pertamina’s Board of Director’s commitment on a company wide Environmental Protection and

Occupational Health and Safety Policy.

The K3LL existence, as an integrated part of the operations, is to support the implementation of the Oil,

Gas and Geothermal objectives for its operations to be safe, reliable and environmentally oriented. K3LL’s

function is to:

� Study matters on Environmental Protection and Occupational Health and Safety in the company’s

periphery.

� Present views, suggestions and opinions on matters related to Environmental Protection and

Occupational Health and Safety.

� Develop systems, procedures and rules on how Environmental Protection and Occupational Health and

Safety should be brought about and maintained.

� Monitor the results of the efforts in the field of Environmental Protection and Occupational Health and

Safety.

� Cooperate with the Government institutions and institutes concerned with Environmental Protection and

Occupational Health and Safety.

The Environmental Protection and Occupational Health and Safety Management System (EHSMS) is

applied in a flexible way so as to enable the company’s operational units to quickly adjust to and meet the

prevailing environmental regulations and standards. The EHSMS is a live document that is periodically

monitored and reviewed to enable continual improvement.

An EHSMS has been applied with the aim of achieving the Corporate aims and objectives for its operations

to be safe, reliable and environmentally oriented. This EHSMS is the base for all operations and is an

integral part of the Oil, Gas and Geothermal business.

2. Key Roles and Responsibilities


3


Pertamina’s philosophy for all its operations is to ensure safe, dependable and environmentally oriented

execution. The EHSMS is one of the ways of applying this philosophy in operational practices and has

been set up to achieve continual improvement through:

� Identifying and setting up the required basic policies, performance standards and the required

operations to support the company in carrying out safe, reliable and environmentally oriented

operations.

� Studying the results of the applied policies, procedures, practices, controls and standards through self

assessment programmes.

� Identifying potential hazards and assessing risks for effective cost control.

� Systematically determining the aim, objectives and targets of the required level of environmental

protection.

� Developing application plans to meet the organization’s aim and objectives.

� Evaluating and analysing performances.

� Assessing the environmental management performance and the future requirements concerned.

PGE has developed their own sector specific EHS guidelines and procedures as part of their own

management plan which addresses the specific needs and requirements of geothermal projects from

exploration through to operation. PGE’s Environmental, Health and Safety Management System (known

as Sistim Manajemen Keselamatan, Kesehatan Kerja dan Lindungan Lingkungan or SMK3LL) includes

policies and procedures that are relevant to the company’s operations and also addresses aspects such as

legislative compliance, EHS training, auditing, managing contractors’, monitoring and reporting and

communication. The SMK3LL is a company wide system in line with the requirements of ISO 9001:2008

Quality Management System and ISO 14001:2004. As part of an ongoing programme, future

commitments include developing an Integrated Management System across the company.

PGE’s existing SMK3LL will form the basis of the EHS management for the development and operation of

the Lahendong Units 5&6 Geothermal Power Plant. During the construction phase of the Project the EPC

contractor will be required to develop a health, safety and environmental (HSE) plan which will be co-

ordinated with the requirements of PGE’s SMK3LL. The Contractor EHS management system (EHSMS)

will include an EHS Policy for the Project and procedures outlining how it is intended to implement EHS

management requirements through the design, construction and commissioning stages of the Project to

ensure that works are executed in a responsible manner, and are in compliance with the national UKL/UPL

process and international World Bank standards. These procedures will cover, as a minimum,

environmental management, environmental monitoring, environmental training, communications,

emergency procedures, record keeping and performance monitoring, reporting and auditing. Once

approved, all employees/contractors should be provided training in the EHSMS and associated procedures

and it should be implemented at all operating units/facilities.

2.2.2 Current Organisational Structure and Responsibilities

PGE’s personnel key roles and responsibilities are set in procedures separate from the SMK3LL, including

organisational and individual working procedures.

There is currently one HSE person stationed at Tomohon site office (local to the Lahendong Units 5&6

project). This HSE person acts as both environmental engineer and safety engineer (hereafter referred

throughout the ESMP as Environmental Engineer). Meanwhile, the Environmental Specialist, Quality

Management Specialist and OHS Specialist and Head of Quality, Environment, Health and Safety are

stationed at the PGE head office. In addition to the HSE personnel at site, there is one public relations

officer employed on-site. The site public relations officer is supported by a one public relations and one


4


government relations members of staff based at the PGE head office responsible for all PGE operations

and projects with input on consultations from the single environmental specialist.

A typical PGE project construction organogram setting out the key roles and responsibilities is presented in

Figure 2.1 below.

Figure 2.1: PT PGE Typical Project Construction Organogram

Source: PGE

PGE will appoint a dedicated person from the project team to oversee environmental management and

implementation (Environmental Engineer under HSE/K3LL department in Figure 2.1 above), and to act as

the main point of contact with the EPC contractor and Steamfield contractors. In addition, for the

Lahendong Units 5&6 Project, the Environmental Engineer will also act as the Occupational, Health and


5


Safety Engineer. The PRO for construction will operate under Legal & Human Relation department in

Figure 2.1 above.

A typical PGE project operation organogram setting out the key roles and responsibilities is presented in

Figure 2.2 below. During operations, the Environmental Engineer will work under the Health, Safety and

Environment (HSE) Manager as identified in Figure 2.2 below. The PRO will work under the General

Service Manager as identified in Figure 2.2 below.

2.3 Capacity Building

2.3.1 Environmental Staff

There is an opportunity for capacity building within PGE to improve the provision of training for the on-site

environmental engineer in order to effectively identify and manage environmental issues associated with

the construction of Lahendong Units 5&6. In part, this is due to lack of environmental specialists within the

Jakarta head office team available to provide the necessary guidance. PGE has taken steps to introduce

new quarterly co-ordination meetings for all of its on-site environmental engineers starting in January 2011

during which training briefings can be facilitated. These quarterly meetings will include all site

environmental engineers from PGE’s operational sites and projects (there are currently nine projects in

total) with PGE head office environmental specialists briefing the site environmental engineers on the

following (but not limited to):

� Updates in any relevant Indonesian environmental regulation;

� Updates in any relevant PGE environmental management systems / procedures;

� Environmental issues arising at other sites for wider dissemination on lessons learnt in order to prevent

repeat occurrences across PGE projects;

� Guest lectures from external agencies when possible (e.g. KLH).

The success of this quarterly co-ordination programme for on-site environmental engineers and also

ongoing monitoring of projects is subject to sufficient environmental specialists being available in the head

office. Currently, the head office includes one environmental specialist who is responsible for the

implementation of environmental management across all operational sites (three sites as PGE and five

sites as joint operation contract or venture) and all projects under development (nine projects in total as of

January 2011). For all projects, this one environmental specialist is responsible for ensuring all

requirements of RPL/RKL or UPL/UKL are met as well as managing the letting of contracts for the AMDAL

and UKL/UPL processes associated with new projects. This also involves co-ordination with various

government agencies to secure AMDAL or UPL/UKL approval (further taking into account that for any one

project, a number of AMDALs or UKL/UPLs may be required to accommodate the overall geothermal

project development as is the case for Lahendong Units 5&6).

In addition, this individual environmental specialist is responsible for the implementation of the PGE

environmental management system and oversight of all on-site environmental engineers. With the

increase training burden for on-site environmental engineers as identified above, this workload is

considered to be far in excess of what the current individual environmental specialist can be expected to

perform and it is therefore identified that additional environmental specialists are required in the head

office. All projects / on-site environmental engineers would further benefit from a greater frequency of

project environmental audits from head office environmental specialists.

PGE currently recognises the shortage in environmental staff in the head office and currently has an

environmental manager position identified. In addition to this environmental manager position, PGE also

has another vacancy for an environmental specialist to supplement the existing environmental specialist.

With these new resources in place, PGE will have sufficient head office resource in order to effectively

provide guidance and oversight for the on-site environmental engineer in the implementation of this ESMP.

PGE has further committed to ongoing training of the head office environmental specialists with a mixture

of internal and external training courses. External training courses include those run within Indonesia by

external agencies such as KLH or EBTKE and also courses specifically in geothermal environmental


7


issues run internationally by higher education establishments in countries such as New Zealand and

Iceland.

The environmental manager, head office environmental specialist and site environmental engineer posts

will be responsible for the range of environmental aspects set out in Sections 4 and 5 of this ESMP.

2.3.2 Social Staff

Similar to environmental staff, there is an opportunity for capacity building within PGE to improve the

provision of training for the on-site Public Relations Officer (PRO) in order to effectively identify and

manage social issues associated with the construction of Lahendong Units 5&6. For the Lahendong Units

5&6 project, there is one PRO employed on-site. In addition, contractors are required to have a

Community Liaison Officer (CLO) identified to work in conjunction with the PGE PRO. One PRO per site is

sufficient and no further capacity is needed. However, there is a requirement for further training for the on-

site PRO as this individual will be responsible in part for the adherence to the Land Acquisition and

Resettlement Policy Framework in the event of any future land acquisition required to support the project.

In addition, the PRO will be required to assist with the implementation of various commitments included

within this ESMP. For example, implementation of the Community Grievance Mechanism, HIV / AIDS

awareness programme, malaria awareness programme and the traffic safety sessions for children.

As for environmental staff, there is insufficient capacity in head office for overall co-ordination / support to

site based PRO. Much of this requirement falls upon the two public relations and government relations

members of staff responsible for all PGE operations and projects with input on consultations from the

single environmental specialist. Currently, PGE has one further position identified for recruitment thereby

expanding the number of head office public relations and government relations staff from two to three

(including one manager). This additional recruitment will alleviate staff shortages in the Head Office and

will enable more frequent visits to the Lahendong Units 5&6 project thereby enabling training of the public

relations specialist on-site to be facilitated.

The head office public relations and government relations and the site PRO posts will be involved in the

mitigation and enhancement activities set out in Sections 4.2 and 5.2 of this ESMP.

2.4 Contractors’ EHS Management

Although not a requirement, preference will be given to selection of contractors who are ISO 14001:2004

and OHSAS 18001:2007 accredited or have equivalent accreditation. This standard places strong

emphasis on the need for continuous improvement of the environment and health and safety management

systems and resultant environmental and health and safety management performance. In particular, for

the power plant and steamfield, as part of the tender process for the construction phase there will be a

requirement that both the EPC contractors, drilling contractors and their respective local partners provide

copies of their EHS policy, procedures, an overview of their management system and an example

construction EHS management plan for review. In addition the EPC contractors and drilling contractors will

be required to include within their proposal for a dedicated EHS professional to be part of the project team

based on site full time.


8


PGE’s appointed EPC contractors and drilling contractors will be required to agree to the following actions:

� Implement the requirements of the construction ESMP as defined in this Volume IV below;

� Provide a construction site layout plan that identifies key activity area including laydown,

accommodation and welfare blocks, parking etc. prior to commencement of works;

� Produce detailed method statements relating to key activities that include specific reference to

requirements of the plans contained herein during the project progression;

� Provide all training necessary to oversee and implement ESMP requirements

� Be responsible for producing comprehensive suite of EHS management and coordination procedures;

and

� Identify a full time person on site with dedicated EHS responsibilities to oversee works on site.

The EPC contractors and drilling contractors project management organisation will be required to be

responsible for sub-contractors’ performance, including ensuring that sub-contractors adhere to the

requirements of the construction ESMP.

The PCDP identifies the need for the EPC contractors and drilling contractors to identify someone within

their full time team to act as Community / Stakeholder Liaison Officer (CLO). This person will be the first

point of contact between PGE and the EPC contractors / drilling contractors for coordinating the

implementation of the PCDP including advance notification of works with the potential to impact on wider

stakeholders and the community, and for processing and closing out of community grievances.


9


3.1 Overview

In parallel to the general ESMP, a number of topic specific documents are required. Prior to each new

phase in the development (such as any new wellpad development / additional wells drilling during

construction or operation), and prior to commissioning of the plant, PGE will develop a number of plans,

policies and procedures to ensure adequate management and monitoring of social and environmental

aspects. Table 3.1 below summarises key policies required. Given the current start of activities at Clusters

26, 27 and 32, timescales for policies relevant to drilling and construction activities have been set as

immediate. PGE’s current management system already covers a number of the policies identified below.

Table 3.1 also makes reference to the requirements to implement or produce a number of management

plans. It is intended that these framework plans will be elaborated by PGE to complement its existing

Environmental, Health and Safety Management System specifically for the Project. Where relevant and

under respective contracts, drilling contractors and the EPC contractors (power plant and SAGS) should be

required to implement corresponding arrangements (as directed within the ESMP). As a minimum, the

following is likely to be required:

� Site waste management plan;

� Recruitment plan;

� Retrenchment plan;

� Waste management plan;

� Traffic management plan;

� Temporary worker accommodation management plan; and

� Chance finds procedure.

Frameworks for these plans are provided within this Volume.

3.2 Identification of Indonesian Geothermal Environment Forum

During the course of elaborating this international quality ESIA, PGE has identified a number of

requirements for internal capacity building (see Section 2.3 above) as well as the need for various

monitoring government agencies to be more familiar with key issues to be addressed by the geothermal

industry as a whole. Although the requirement for government agency capacity building has been

identified, it is beyond PGE’s remit as a private company to be responsible for training government

agencies that have an institutional responsibility for monitoring PGE’s project development activities.

Furthermore, the identification of need for institutional agency capacity building should be done in

agreement with the overall Indonesia geothermal industry, not PGE operating in isolation as part of a

project specific ESMP. Such a collective endeavour will ensure that any agency capacity building is aimed

at serving the requirements of the Indonesian geothermal industry as a whole to be benefit of all industry

stakeholders.

In order to further a collective endeavour, PGE is committed to the formation of an industry-wide

geothermal environment forum with invitations extended to all existing operators within Indonesia. Interest

has also been registered by other geothermal operators. A regular Indonesian geothermal environment

forum meeting represents an opportunity for environmental issues facing the geothermal industry as a

whole to be discussed, agreed and presented as a collective for discussion with government stakeholders

(notably KLH). Such an approach will enable the geothermal industry as a whole to identify potential

obstructive barriers to geothermal development as well as raising awareness of important responsibilities

for the geothermal industry to be cognisant of (such as robust assessment of potentially harmful emissions

3. Plans, Policies and Procedures


10


to local communities and more regular identification of precautionary abatement to address such

emissions). A geothermal environment forum can propose and agree with the government a potentially

more streamlined environmental management process for operations where a potential re-designed

UKL/UPL process can be configured bespoke to the geothermal industry allowing more focus on issues

that are considered of greatest / most importance.

In order to provide impetus for the geothermal forum formation, for its effective operation, and for securing

necessary support from all member geothermal operators, Mott MacDonald recommends that PGE

represents to the Indonesian government the need for an initial grant mechanism request to be made to,

for example, an international donor agency. This could be administered via KLH and / or technical

department New Energy, Renewable and Energy Conservation - EBTKE (under Ministry of Energy and

Mineral Resources). An initial estimate of meaningful start-up budget for the forum is $300,000 with an

annual budget thereafter of $100,000. As a suggestion, the start-up budget would be aimed at external

support engagement to independently elaborate objectives for the geothermal environment forum (collating

objective aims from all respective operators), an external chair for an inauguration workshop event drawing

on a range of national and international contributors. The event organiser would be responsible for

collating the findings of the forum together with identification of priority issues to be taken forward in future

forum workshops with an eventual aim of presenting an industry consensus to relevant government

agencies.

It is hoped that through the formation of an Indonesian geothermal forum, the industry as a whole can build

capacity which can thereafter be communicated through to relevant government agencies.

6.5 Waste Management Plan

This subsection presents a framework of the Waste Management Plan to be elaborated and implemented

by the EPC contractors and drilling contractors during construction and thereafter by PGE during

operation. The following key steps will be considered within the WMP elaborated for respective phases of

the Project:

� Identify who is responsible for each key stage and inform individuals of their responsibilities. They will

be required to hold sufficient authority to ensure compliance with the WMP by other site operatives;

� Identify the types and quantities of waste - all waste streams that will be produced during construction,

operation and decommissioning require to be identified;

� Identify waste management options - Where hazardous wastes are being generated, particular attention

to the arrangements for identifying and managing such waste will need to be addressed and procedures

put in place;

� Identify suitable waste management sites - the location of waste management sites will need to be

identified (through co-ordination with local government), ideally the most local sites should be used to

minimise transportation costs. Use licensed waste disposal contractors that comply with the

environmental legislative requirements of the local and national area;

� Training - all staff must be trained to ensure they understand the requirements of the WMP;

� Plan - using the steps above, establish indicative percentages of the waste quantities to be produced

over the life span of the Project;

� Measure - the quantities of wastes produced should be recorded on a monthly basis, and where

possible measures taken to re-use, reduce or recycle waste as appropriate; and

� Monitor - throughout the Project life cycle, waste management on site should be monitored, to ensure

compliance with the WMP;

� Hazardous Classes – hazardous wastes should be classified and treated according to national

requirements ;

� Identify waste management options - as described in the construction and operational ESMPs provided

in Volume II, a waste hierarchy of reduce, reuse, and recycle and needs to be considered and

prepared. Where hazardous wastes are being generated, particular attention to the arrangements for

identifying and managing such waste will need to be addressed and procedures put in place;

PGE will review and approve the EPC contractors and drilling contractors elaborated WMPs for the

construction phase of the Project.


60


6.6 Traffic Management Plan

6.6.1 Introduction

This subsection presents a framework of the Traffic Management Plan to be elaborated and implemented

by the EPC contractors and drilling contractors during construction and thereafter by PGE during

operation. PGE will review and approve the EPC contractors and drilling contractors elaborated Traffic

Management Plans for the construction phase of the Project. Pre-defined access routes will be used by

long, wide and/or heavy load vehicles transporting power plant components, e.g. turbines, condensers,

cooling towers, electrical equipment. These routes will be agreed with the relevant authorities in advance

and the police will be notified.

A number of abnormal loads will be generated through construction activity associated with:

� Drilling rigs

� Construction plant

� Steam turbine – engine/generator;

� Condenser – prefabricated elements; and

� Cooling tower – prefabricated elements.

6.6.2 Delivery Plan

Power plant components shall be delivered to site in accordance with the following:

� Plant to be delivered in sufficient time to meet the agreed erection programme;

� Plant to be delivered in accordance with the requirements of the local municipality, police and road

authority;

� Loads to be delivered to site by road and stored on site. It will be the contractor’s responsibility to

identify a suitable storage location and approved by PGE and obtain any necessary authorisations;

� A pilot escort vehicle should be used to provide an escort for all abnormal load vehicles travelling to the

site. The general preference in these situations is to employ a convoy system, with a vehicle at the front

and rear to warn oncoming vehicles of the approaching load. The escort would also help to minimise

disruption of flow for other road users by pulling the convoy over at pre-identified locations to allow build

up of following traffic to pass. Drivers responsible for operating the convoy should be fully briefed on the

route, where and when to make the pre-defined stops, and be aware of all contingency measures in

place in the event of an incident occurring. All vehicles and lead traffic management staff shall be in

contact with the use of two-way radios;

� Employ additional traffic management staff (to be agreed with police if required prior to transportation)

for any locations where pedestrians are most likely to be present;

� Ensure clear roadways to allow transporters passage through geometrically constrained sections of the

route. At strategic locations parking will need to be restricted at times of delivery; and

� Develop contingency plan, in consultation with the police, to cover an event where an abnormal load

becomes immovable on the public road, for any reason (for example, breakdown, un-anticipated route

restriction, accident).

A driver’s induction for abnormal load vehicles will include:

� Safety briefing including detail of all contingency measures;

� The need for appropriate care and speed control;

� Identification of specific sensitive areas; and

� Clarification of identified route, the requirement not to deviate from this route, the requirement to adhere

to convoy system and pull over at pre-defined points to allow build up of traffic to pass.


61


6.6.3 Site Traffic

The following points will apply to general site traffic:

� General site traffic and general construction traffic will not require the presence of an escort when

travelling to and from site;

� Drivers shall be aware of route and contingency measures as pre-defined at induction stage;

� Drivers of HGV are to be briefed in good road practice and will be instructed to pull over on narrow

sections of road to allow build up of traffic to pass;

� All general site traffic and construction vehicles, including concrete related deliveries, will run to

coincide with site working hours;

� Normal load construction vehicles will use a defined route, which will need to be agreed for each

construction phase;

� Signage will be kept to a minimum, however temporary direction signs indicating local routes to site and

site entrances will be required at strategic locations on local roads;

� The detailed signing arrangement will be agreed between the appointed contractor in close liaison with

the local municipality and the police service;

� Wherever possible, arrangements will be made for site workers to be transported to site via shared

transport to minimise unnecessary traffic movements locally; and

� The contractor will be required to implement induction procedures and regular up-dates for all drivers to

establish and promote an overall culture of safety and awareness of other road users.

6.7 Temporary Worker Accommodation Management Plan

This subsection presents a framework of the Temporary Workers Accommodation Management Plan to be

elaborated and implemented by the EPC contractors and drilling contractors during construction. PGE will

review and approve the EPC contractors and drilling contractors elaborated Temporary Worker

Accommodation Management Plans for the construction phase of the Project.. Temporary Worker

Accommodation Management Plans will be developed for all new construction accommodation camps

prior to them being inhabited as per either EPC or drilling contract requirements. These plans will be

developed in accordance with international best practice guidance, as exemplified by “Workers’

accommodation: Processes and standards, a guidance note by IFC and the EBRD” (2009) and follow a

6.8 Chance Finds Procedure

6.8.1 Overview

Effective protection of cultural heritage is based on an understanding of the key issues, appropriate

assessment and the correct action to minimise damage or loss. As unknown features / objects could be

encountered during works, in particular earthworks, a ‘chance finds procedure’ should be in place to stop

works and require investigation by an archaeologist in case of such findings.

This section of the ESMP contains a ‘chance finds procedure’ for use by the EPC contractors and drilling

contractors. PGE will consult with the relevant authorities (the Preservation of Archaeological Heritage

Office (Balai Pelestarian Peninggalan Purbakala) and Archaeology Office (Balai Arkeologi)) to ensure that

it is acceptable to them and that it complies with local and national regulations. Updates or amendments

should be made by the EPC contractors and drilling contractors where appropriate.

6.8.2 Framework Chance Finds Procedure

6.8.2.1 Definitions

‘Chance finds’ are defined for the purposes of this procedure as physical cultural resources encountered

unexpectedly during project implementation.

‘Physical Cultural Resources’ (PCR) are defined as movable or immovable objects, sites, structures,

groups of structures, and natural features and landscapes that have archaeological, palaeontological,

historical, architectural, religious, aesthetic, or other cultural significance. Their cultural interest may be at

the local, provincial, national or international level.

6.8.2.2 Ownership

The ownership of any chance finds discovered on the Project will be determined by the Preservation of

Archaeological Heritage Office (Balai Pelestarian Peninggalan Purbakala) and Archaeology Office (Balai

Arkeologi) at provincial level. These agencies fall under the Archaeology Research and Development

Centre and Directorate of Archaeology, which are at national level.


63


6.8.2.3 Recognition

So that the contractor and employees such as equipment operators and supervisors on the Project can

identify physical cultural resources, training will need to be given. Prior to commencement of works the

EPC contractors and drilling contractors (in collaboration with PGE) will consult with the authorities

mentioned above in order to arrange training for its employees. PGE will monitor this process to ensure

that effective training is given to the correct members of the workforce.

6.8.2.4 Procedure Upon Discovery

Suspension of work:

� Upon discovery of physical cultural resources, the responsible contractor shall stop work (responsible

contractor will vary depending upon which Project component the find is associated with – e.g. EPC

contractor for Power Plant area or SAGS EPC contractor for pipeline corridor area).

� In some cases, all work will need to be suspended, in others just the work in the immediate vicinity of

the find will need to stop, in others still, all work within a certain radius of the find must cease. This

issue will depend on the type of find and will be informed by a qualified archaeologist.

� After stopping work, the contractor must immediately report the discovery to PGE’s Project Manager.

The contractor may not be entitled to claim compensation for work suspension during this period.

� PGE’s Project Manager may be entitled to suspend work and to request from the contractor some

excavations at the contractor’s expense if he thinks that a discovery was made and not reported.

Conditions and requirements for work stoppage:

� With the approval of PGE’s Project Manager (PM), the contractor is then required to temporarily

demarcate and limit access to the site, or, the PM may decide that the item can be removed and work

may continue, for example where the item is a single coin of archaeological value.

Chance Find Report:

� The contractor will submit a Chance Find Report within one day of the find. This will record the

following information:

− Date and time of the discovery;

− Location of the discovery;

− Description of the PCR;

− Estimated weight and dimensions of the find; and

− Temporary protection that has been implemented.

The Chance Find Report will be submitted to PGE’s Project Manager, and other concerned parties as

agreed with the provincial cultural authorities, and in accordance with national legislation (to be agreed

upon submission of this Chance Finds Procedure to the provincial authorities for their comment/approval).

PGE’s Project Manager is required to inform the cultural authority immediately following the submission of

the Chance Find Report.

6.8.2.5 Arrival and Actions of Cultural Authority

The cultural authority (Preservation of Archaeological Heritage Office) undertakes to send a representative

to the discovery site, who will arrive within a stipulated time frame, such as 24 hours if all work has been

suspended (details will be agreed between the authority, PGE and the contractor). The representative will

determine the action to be taken which may include, but will not be limited to:

� Removal of the PCR(s) deemed to be of significance;


64


� Execution of further excavation within a specified distance of the discovery point;

� Extension or reduction of the area demarcated by the contractor.

These actions should be taken within seven calendar days of the representative arriving on site in the case

of the suspension of works.

The contractor may or may not be entitled to claim compensation for work suspension during this period (to

be elaborated by PGE within the tender documents).

If the cultural authority fails to arrive within the stipulated period (for example, 24 hours), PGE’s Project

Manager will have the authority to extend the period by a further stipulated time.

If the cultural authority fails to arrive after the extension period, PGE’s Project Manager may have the

authority to instruct the contractor to remove the PCR or undertake other mitigating measures and resume

work. Such additional works can be charged to the contract. However, the contractor may not be entitled

to claim compensation for work suspension during this period.

6.8.2.6 Further Suspension of Work

During this seven calendar day period (see above section on arrival and actions of cultural authority) the

cultural authority may be entitled to request the temporary suspension of the work at or in the vicinity of the

discovery site for an additional period of up to 30 calendar days or longer if deemed necessary.

The contractor may, or may not be, entitled to claim compensation for work suspension during this period

(to be elaborated by PGE within the tender documents). However, the contractor will be entitled to

establish an agreement with the cultural authority for additional services or resources during this further

period under a separate contract with the cultural authority.

6.8.2.7 Resumption of Work

Following approval from the cultural authority (Preservation of Archaeological Heritage Office), PGE’s

Project Manager will issue the contractor with the instruction to recommence works.

6.8.2.8 Review

PGE’s Project Manager will review the process and amend it as necessary to ensure efficiency and

effectiveness of the chance finds procedure in the future.

7.1 Overview

This section presents an ambient H2S Monitoring Programme which will be implemented within the study

area, in light of the air quality assessment results described within the ESIA volume II and III. While results

have been shown to be well within the WHO guideline value at residential receptors, following the

precautionary approach an initial period of monitoring will be undertaken in order to confirm that no

adverse air quality effects result from actual operations. The introduction of a Monitoring Programme is in

accordance with the World Bank Group General EHS Guidelines for Geothermal Power Generation which

notes that:

“Where the potential for community exposure is significant, examples of mitigation measures include:…

� Installation of a hydrogen sulfide gas monitoring network with the number and location of monitoring

stations determined through air dispersion modeling, taking into account the location of emissions

sources and areas of community use and habitation;

� Continuous operation of the hydrogen sulfide gas monitoring systems to facilitate early detection and

warning;”

As described within the ESIA volume II and III, H2S concentrations are predicted to be well below the

occupational exposure limits. Nevertheless, installation of an on-site H2S monitoring system is to be

included within the EPC contract scope of works to assess worker exposure to H2S concentrations, as

described in the Project Feasibility Study 2010. Beyond these measures, no further consideration is

therefore given to occupational H2S monitoring within this ambient H2S Monitoring Programme. Similarly,

H2S emissions monitoring will be carried out by PGE and therefore the focus of this Monitoring Programme

is ambient H2S concentrations beyond the site boundary relating to community exposure only.

In order to simplify the management, cost and delivery of the ambient air quality monitoring, a local

supplier or third party will be identified to provide the equipment and/or undertaken maintenance.

7.2 Purpose

The overall purpose of the Monitoring Programme is to determine the change in ambient concentrations of

H2S, in areas of public exposure, as a result of the project in the context of the WHO ambient air quality

guideline for the protection of human health1. This is achieved by collecting data on ambient H2S

concentrations in public areas near to the project site during the operation of the Plant.

7.3 Schedule

The Monitoring Programme will commence upon power plant commissioning and will continue for the first

year of operations. Thereafter, the continuation of monitoring will be assessed on an annual basis. If the

2nd

maximum annual 24-hour concentrations are found to be regularly above 75% of the WHO guideline,

monitoring will be continued for further annual periods.

_________________________

1 The WHO guideline is 150 µg/m3 averaged over 24 hours

7. Air Quality / H2S Monitoring Programme


66


7.4 Data Collection Methods

Equipment designed specifically to monitor for 24-hour averaging periods is not readily available. Diffusion

tubes measure averages over long periods that cannot be readily compared to a 24-hour standard.

A permanent continuous analyser enclosure (which would provide hourly or sub-hourly estimates that

could be averaged to 24-hours) is not recommended given that concentrations at residential receptors are

predicted to be low and the relative expense of such a solution. However, portable H2S monitors are

available which will be used as a substitute. In this case, the portable monitoring will be affixed in a

suitable location (e.g. at the closest property) in order to act as a permanent monitor.

Portable units are self-contained, battery or mains powered and include data loggers. A mains power

supply is used (through agreement and compensation as appropriate to the electricity bill payer) as use of

batteries could require frequent changes. Depending on the probe, at the relevant frequency, a

representative from PGE will recover the hand-held monitor, download the relevant data and replace for

further monitoring. This is likely to be at most weekly depending on the capacity of the probe to store

information. Ongoing calibration will be undertaken in the field but would require some initial training if

PGE were to undertake this. Again depending on the probe, calibration would be required periodically, and

will be undertaken in conjunction with the data download for efficiency. As per the manufacturer’s

requirements, the probe will be returned to the supplier of manufacturer annually or bi-annually for a full

calibration and servicing. These units have an applicable limit of detection in order to monitor against the

WHO guideline value for 24-hour exposure.

A local or regional supplier will be used in order to reduce costs and simplify management and

deployment.

7.5 Locations

Monitoring will be undertaken simultaneously throughout the first full year of operation at the two nearest

villages to the site, Tonsewer and Pinabetengan. Locations will be chosen on the south or south-western

fringes of these settlements representing residential buildings that are closest to the plant.

Consultation will be undertaken with village heads of the local communities in order to identify a location

where the probes could be mounted. This may be within the property of an individual resident or on a

community structure. The specific location will be dependant on the availability of suitable mounting points

for the equipment, therefore potential sites will be identified prior to purchase of the equipment.

As the probes are designed for hand-held use, a suitable mounting and enclosure will be required to

ensure that the equipment is protected, in particular that they are covered from rainfall. The site

identification will consider this requirement.

7.6 Quality Assurance/Quality Control

Calibration of the monitors shall be carried out in accordance with the manufacturer’s instructions using the

supplied calibration kit (based on reference gas methods). This involves using the supplied kit to expose

the probe to reference levels of the pollutant in order to ensure it accurately records ambient

concentrations. The representative of PGE that will be responsible for maintaining the monitor will

undertake initial training which would be provided by the supplier/manufacturer of the equipment.


67


In addition, the equipment will be required to be returned to the manufacturer for full calibration and

maintenance. Depending on the manufacturer, this would be undertaken annually or bi-annually and

certification should be provided.

7.7 Analysis, Reporting and Actions

7.7.1 Normal Reporting

Every quarter a report will be produced based on the preceding calendar months’ data, detailing the

following information:

� Validated H2S data from the continuous analyser and data capture rate;

� Summary data for comparison with the WHO air quality guideline:

− Mean 24 hour concentrations for the period

− Maximum 24 hour concentrations for the period

− The number of occasions (if any) when the 24 hour mean concentration exceeded 150 µg/m3

� Discussion of any salient quality assurance issues;

� Copy of the calibration report (if applicable); and

� Details of any investigation or remedial action taken as a result of an exceedence.

In all cases the target data capture rate for an averaging period should be over 75%. In the event that data

capture rates are below this level, this will be noted in the quarterly report and steps taken to remedy any

recurring causes.

7.8 Costs

The estimated initial purchase cost of two portable monitors is $14,000. This includes the cost of the

monitors themselves, replacement batteries or power supply, reasonable mounting and coverings for the

probes, bi-annual calibration (for the first year) and initial training. However a suitable existing mounting

point is assumed, potentially with a local resident or community structure, which will limit the initial

installation costs.

Ongoing annual costs (second year on) are estimated at around $3,000 for replacement parts and

calibration.

7.9 Responsibilities

The installation (including power supply provision), operation, maintenance and reporting procedures set

out above for the Monitoring Programme will be the responsibility of PGE.
