NTRODUCTION

1.1 BACKGROUND

PT. PERTAMINA EP has planned to develop a gas field, which is located in Banggai Regency, Central Sulawesi Province; this is organized by the Team of Gas Development Project of Matindok (PPGM). By the time of document compilation, complying with the Law No. 22 of 2001 regarding Natural Gas and Oil, role of PT PERTAMINA has changed, whereas the management of Upstream Oil and Gas has been shifted to the Implementing Body (Badan Pelaksana) of Oil and Gas (BPMIGAS). According to the Law No. 22 of 2001 regarding Natural Gas and Oil, PT PERTAMINA (Persero) forms a subsidiary company that is PT PERTAMINA EP, which handles the activities of Upstream Oil and Natural Gas. PT PERTAMINA-EP is formed based on Notary Deed number 4 on 13 September 2005.

PPGM is an important project for oil and natural gas industries in Indonesia and will play important roles in maintaining and strengthening Indonesia’s position as the biggest exporter of LNG in the world. The development of PPGM will improve contribution of oil and natural gas sector in rendering foreign-exchange to the country and partly for substitution of domestic oil fuel. PPGM is expected to operate in the year 2009.

The Gas Development Project of Matindok is an activity of developing complete facilities, starting from producing natural gas from both explored wells and developed wells plan coming from 5 natural gas fields, including: gas field of Donggi, Matindok, Maleoraja, Sukamaju, and Minahaki. Later, the gas is channeled through pipes to the LNG refinery, in this case the Donggi-Senoro LNG or DSLNG which will then be transported through the harbor using LNG oil tankers.

(6)

The gas production capacity from Matindok Blok is estimated ± 100 MMSFCD (gross), containing ± 850 bopd, and ± 2,500 bwpd of water production, with an expected 20 years of production based on the existing gas reserve and the result of economical studies for field development. The gas product contains ± 2.5% CO2, ± 3.000 ppm total sulfur and possibly other

elements. According to the enclosure letter of the State Minister of Environmental Affairs Decree No. 11 of 2006, regarding the Kind of Plans and/or Activity that must be completed with the Environmental Impact Assesment (EIA), this activity is obligated to compile an EIA because it exceeds the EIA/AMDAL minimum limit of 30 MMSCFD.

Therefore, the project proponents of the Gas Development Project of Matindok (PT. PERTAMINA EP-PPG) is obligated to perform EIA/AMDAL studies, because this activity is expected to have major and significant impacts to the environment. This EIA/AMDAL study is an effort to prevent and overcome negative impacts and develop positive impacts.

The positive impact on the environment from the gas development activities are the increase of natural gas producing regions, fulfiling public energy needs, and stimulating other business opportunities. Besides positive impacts, this activity is also unexpectedly bring negative impacts to the environment. According to the commitment and policy of HSE PT. PERTAMINA EP-PPGM and as their concern to the surrounding environment and in accordance to the commitment of PT. PERTAMINA EP-PPGM to conduct environmental-friendly activities, PT. PERTAMINA EP-PPGM will compile the Environmental Management Plan (RKL). This Management Plan is amongst the effort to handle and manage the environment in conducting the Matindok Gas Development Project in Banggai Regency, Central Sulawesi under the existing laws and regulations.

This Management Plan (RKL) is an important document not only to the project proponents but also to other sectors, including the Local Government and the community. This Management Plan is expected to support the success of the development of mine and energy and also to support environmental-friendly development in the region. This Management Plan can also enforce other sectors to participate in implementing environmental based development. By implementing the upstream and downstream business concept, the responsibility of the implementation of the environmental management activity is also split regarding to the concept explained in the ANDAL document. The upstream environmental management is fully the

(7)

responsibility of PT Pertamina EP while the downstream environmental management is of Donggi-Senoro LNG (PT DSLNG).

NVIRONMENTAL MANAGEMENT

APPROACH

The environmental management program towards the environmental components that suffers basic changes (significant impact) whether positive or negative, caused by the Matindok Gas Development Project activities plan, is conducted in three approaches, which includes technological, economical, and institutional approaches in order to prevent and overcome negative environmental impacts, and develop positive environmental impacts. Prevention is an effort to prevent negative impacts from occurrance. This effort may include adjustments of process designs, or environmental-friendly choice of equipment. Whereas to overcome negative impacts is an effort to not allow the increase of the negative impacts or to minimize or eliminate the impacts when they arose.

Besides preventing and overcoming negative impacts, the environmental management program also includes development of positive impacts.

2.1 TECHNOLOGICAL APPROACH 2.1.1 Waste Management Technology 2.1.1.1 Waste from Drilling Wells Activities

A. Drilling Mud

The drilling mud used is water based mud and synthetic oil based mud made from crude palm oil (CPO). Both muds are non-toxic. The use of these non-toxic mud decreases the possibility of ground water contamination if there is rainwater flow from mud pit.

The impact of the development well drilling operation towards the water quality occurs in the operational phase. The source of the impact comes from the following activities: • Drilling waste, in the form of used drilling water, remains of drilling mud, and

(10)

• Drilling water waste from washing of drilling equipment and rig floor when the activity takes place, estimated ± 2,916 m3_{(90 days x 32.4 m}3_/day)

• The management of the used drilling mud or mud that has been repeatedly circulated into the drilling well causing it to cross the tolerance level of solid substance, unable to be removed using separating equipments (solids control). The decrease of mud from partial loss or total loss circulation in the formation while mud was circulated through the coverless annulus and in the pipe connection is estimated ± 10% of the total initial amount of mud, therefore the remains of the drilling mud in the drilling of the development well is ± 970.1 m3_.

• Solid wastes, in the form of cuttings produced by the drilling process, estimated ± 538.9 m3_{, counted from the surface are as follows:}

- Route 30” (0-30 m), produces 3.14 x (18 x 0.0254 m)2 x 30 m = 19.7 m3 amount of cuttings - Route 20” (30-600 m), produces 3.14 x (13 x 0.0254 m)2 x 570 m = 297.9 m3 amount of cuttings - Route 13 3/8” (600-1,500 m), produces 3.14 x (8.75 x 0.0254 m)2 x 900 m = 93,0 m3_{amount of cuttings} - Route 9 5/8” (1,500-2,900 m), produces 3.14 x (6.125 x 0.0254 m)2 x 1,400 m = 106.4 m3_{amount of cuttings.} - Route 7” (2,900-3,500 m), produces 3.14 x (4.25 x 0.0254 m)2 x 600 m = 21.9 m3_{amount of cuttings.}

The volume of the container is ± 1,500, enough to collect ± 612 m3_rainfall₍_the _land

width is approximately 10,000 m2_{, maximum rainfall up to 68 mm, rain duration for one}

hour and receiving tank building coefficient = 0.9).Scheme of solid waste management is shown in figure 2.1 and figure 2.2.

B. Handling/Management

After drilling, cuttings material are tested through Toxicity Characteristic Leaching Procedure (TCLP) with Ba, Cd, Hg, Pb, Ag, Cr6+_{, Zn dan Cu as perimeters. If the TCLP}

result shows that the solid wastes fulfill the requirements to be disposed, the used mud will be mixed with limestone and the container will be covered with top soil. If the TCLP result shows the solid waste fail to fulfill the requirements, the waste management will refer to the government policy (PP) No. 18/1999 jo PP No. 85/1999 and the practice regulation.

(11)

Drilling Waste Management:

a. Fresh mud management will be conducted using MSDS and toxicity analysis of fresh mud before being used.

b. The drilling waste management that consists of liquids and solids (waste waters, mud remainder and cuttings) refers to the regulation of the Minister of Energy and Mineral Resources (ESDM) No. 045 of 2006. Several containers and pools to be used are as follows:

• Cutting container/Ground Pit 1 (15 m x 4.5 m x 4 m) used to separate solid waste (cuttings).

• Oil catcher container/Ground Pit 2 (5.6 m x 4.6 m x 1.5 m) used to separate oil and drilling water waste. If oil is found in this container, it will be sucked using a skimmer and burned in the burn pit.

• Coagulation container/Ground Pit 3 (4.2 m x 35 m x 1.5 m) used to help the material coagulation process, where in certain conditions are added with tohor and alum.

• Water disposal container/Ground Pit 4 (11 m x 3 m x 1 m), filled withpalm fiber, small rocks, and wood charcoal in order to eliminate finersolid particles, remove odor, and to clarify water.

The final waste waters produced will be analyzed with TCLP. If the result shows the waste water contains toxic and hazardous materials, it will then be managed according to the related regulations. On the contrary if the waste water does not contain any toxic and hazardous materials or still meets the standard quality, then the water will be disposed to the nearest river. The solids present in the cutting pool and container will be buried with soil and be reused for vegetation sites.

A more detailed scheme of the drilling mud management is shown in figure 2.1, while the detail designs of the ground pit, oil catcher container, coagulation tank, and water disposal tank are shown in Appendix 3.

c. Cuttings processed using oil mud will be tested for oil (oil on cuttings) by TCLP. The management of cuttings and remaining drilling mud (solid wastes) will be in accordance to the regulation of the Minister of Energy and Mineral Resources (ESDM) No. 045 of 2006, regarding Drilling Mud, Mud Wastes, and Cuttings Management on the Oil and Natural Gas Drilling Activities, and Individual Work plan on In-land Drilling Waste Management of PT PERTAMINA-EP No. C-003/EP5000/2006-S0. Drilling of wells using oil/synthetic based mud is not to be disposed to the environment but to be reconditioned for further applications.

(12)

EMPMatindok Gas Development Project _II-4 C. Liquid Waste

Waste water treatment is conducted physically and chemically. Other waste waters coming from bath rooms will be collected in septic tanks, whereas the rain water is channeled to the sewage system.

D. Domestic Waste

Domestic waste refers to the waste coming from employee’s regular activities in the location, which includes bathing, washing, and cooking. Domestic waste may be solid or liquid. With the large amount of employees and considering the morphological conditions of the surrounding environment, domestic waste has the potential to become the source of impacts.

Solid and liquid domestic wastes come from domestic employee activities, packing materials of food and drinks, and drilling materials. An effort to manage these wastes is by providing containers as follows:

• Biological waste will be collected in septic tanks (1.5 m x 2 m x 2 m).

• For solid waste coming from employee activities and degradable used packing material (food and drink packing material, mud bags, cement bags, and wood/carton packing material) will be collected and burned in the garbage container (0.75 m x 0.75 m x 1 m). Whereas the materials difficult to degrade (plastic drums and plastic) are to be collected in a certain place in the activity location. After the activity ends, the degradable materials are stocked up in the containers, whereas the materials that are difficult to degrade are brought out of the location, to be disposed in the nearestdump site.

E. Gas emission

Gas emission from DST activities will be managed as follows:

• Gas will be burned in flare pit after separated through a separator, allowing toxic gas such as H2S to break down and become non-toxic.

(13)

Figure 2.2 Flowchart of Liquid Waste/Water Base Mud

H2S gas that exit during the formation along with the drilling mud in the drilling process

will be managed as follows:

• H2S gas contained in the drilling mud is dissolved in calcium hydroxide (Ca(OH)2)

suspension in the mud container, to form sulfide salts.

• One of the procedures to handle the unknown amount of free H2S gas, is to

temporarily stop the drilling activity and evacuate all the drilling workers and community surrounding the site. Evacuation of the community will only be done if the course of wind is headed to the settlement.

An act of prevention to detect any free H2S gas promptly:

• Facilitating the drilling installation with large fans headed towards the course of wind. • To equip H2S gas sensors in certain places such as: shaleshaker, mud tanks, and

drilling floor.

• Controlling H2S gas sensors at the hazardous state (H2S limit = 10 ppm).

• Providing Breathing Apparatus (BA) and H2S gas personal detector in the drilling

location to ensure human safety. 1. Ground Pit #1 2. Oil Catcher 3. Ground Pit #2 4. Coagulation tube (vessel) 5. Ground Pit #3 6. Filtration tube (vessel) 7. Ground Pit #4 8. Clean water tub

G. Management of Planted Pipes towards Earthquake Disaster

In the research region, there are some sources and several occurrences of seismic activity. There are also signs of possibilities of future earthquakes. This might effect the stability and integrity of the pipelines that by then will be placed by PERTAMINA EP-PPGM. Therefore, in the pipelines placements process, PT.PERTAMINA EP-PPGM has to anticipate the earthquakes by protecting the pipelines, to ensure the earthquakes will not disrupt the stability of the position and integrity of the planted pipes.

Measures to protect the pipes are as follows:

a. Pipes must be equipped with additional monolite casing.

b. The dug holes of the pipes must be given sand, making the outside layer of the planted pipes stocked in sand in which the matrix are adjustable to shape position towards the change of pattern and shape of the stocked sand area.

2.1.1.2 Waste of Construction Activities and Complex Gas Processing Facilities (GPF) Operations.

A. Liquid Waste

After the process units and pipe installation ends, a hydrostatic test is performed on the pipes and containers used in the process. This hydrostatic test will require water taken from surface water (river water). The used water from the test will then be disposed to the nearest river. If necessary, the used water will be analyzed to ensure the quality of the water based on the State Minister of Environmental Affairs Decree No. 4 of 2007 regarding Waste Water Quality Standard for Oil, Gas, and Geothermal Activities.

Liquid Waste from the Gas Processing Facilities (GPF) comes from the water formation separating system. The waste contains several pollutants especially condensate/oil, sulfur, and suspended solids. In order to be disposed in the environment (river), the waste must be processed using waste water treatment equipments or through water injection.

Liquid domestic waste from the construction employees will be collected in septic tanks.

B. Solid Waste

Solid waste such as used food packages, cans etc. will be collected and disposed to the nearest dump site (TPA), in the Banggai Regency. The domestic waste at the Gas Processing Facilities (GPF) will be collected in septic tanks. The remaining solid waste of the Gas Processing Facilities (GPF) construction will be collected and brought back by the PT. PERTAMINA EP-PPGM contractor.

(16)

EMPMatindok Gas Development Project _II-8 C. Gas emission

The production facilities of the GPF has 5 sources of gas disposal, that consists of compressor gas, Low Pressure (LP) vent, High Pressure (HP) flare, heating medium heater and power plant. From these 5 sources, HP flare is an interminent source. But based on the types of pollutants, only LP vent that contains H2S gas, while the others

contain CO2.

The management effort is done by designing equipments that meets the gas emission standard (based on the Decree of the Minister of Environmental Affairs No. 129 of 2003). Cosiderations taken in flare design are as follows:

1. Speed of emitted gas, directly related with the above diameter to obtain speed between flashback and blow out or on a certain lift-off;

2. Radiation intensity, related to the combustion heat spreading location;

3. Dispersion of remaining gas from combustion process, related to the location of the gas spread.

4. Position of equipments, related to the placement of equipment with a minimum 90 m distance from the hazardous source.

D. Sulfur Recovery Unit (SRU)

Separation of sour gas from impurities conducted by CO2/H2S removal will produce gas

emission mostly consisting CO2 and H2S. Because H2S gas is toxic, it is necessary to build

a Sulfur Recovery Unit (SRU) to process the H2S gas into sulfur in a solid or powder

state. It is estimated that 110 tons of sulfur is produced each day. Those sulfur will be collected in a special container and later on be marketed.

E. Contaminated drainage water

Around the GPF complex, an 8 km long, 60 x 30 cmsewagesystem will be built to collect rainwater, whereas the possibly oil contaminated water from the GPF complex will be collected and processed in waste water treatment facilities. Condensate/oil trapped in the waste water treatment will be sucked and repumped to the tank. Waste water from the waste water treatment will be disposed to the pools surrounding GPF. The processed water is to meet the quality standard in accordance to the Minister of Environmental Affairs Decree No. 4 of 2007, before it is disposed to the environment.

(17)

EMPMatindok Gas Development Project _II-9 F. Fire fighting agents

The Fire fighting agents used must be from halon free substances (Non-Ozone Depleting Substances/Non-ODS) to avoid damage of the ozone layer.

G. Spent completion fluid from production wells and completion activities

Liquid waste from produced water containing inorganic salts and hydrocarbon will be channeled to the waste water treatment facility and disposed to the environment after meeting the quality standard based on the Decree of the Minister of Environmental Affair No. 4 of 2007.

H. Oily Sludge

In accordance to the Pertaminan Decree No. Kpts-074/C00000/2001-S0, regarding the Sludge Waste Management Guideline on Pertamina’s operational activity, stating that oil mud can be reused, processed or sold with Pertamina’s agreement. The treatment of oil mud containing more than 20% weight is to be conducted physically-chemically, where the oil separating product can be reused, while the solids goes through TCLP. If the TCLP result is under the quality standard, solidification or land fill is necessary. And if the result is above the quality standard, it will be processed by the third party.

2.1.1.3 Waste from the Pipeline Construction Activities A. Liquid waste

Domestic liquid waste from construction workers will be collected in septic tanks. Hydrostatic tests will be performed after pipe instalations. This hydrostatic test will require water taken from surface water (river water). The used water from the test will then be disposed to the nearest river. If necessary, the used water will be analyzed to ensure the quality of the water based on the quality standard in accordance to the Minister of Environmental Affairs Decree No. 4 of 2007.

B. Solid waste

Solid waste coming from leftover pieces of pipes, used cans, and other sources will be collected and handled by the contractor of PT. PERTAMINA EP-PPGM. Domestic waste will be collected in septic tanks.

(18)

The zero discharge principle is applied in the waste management system demanding facilitation of solid construction waste containers and making an effort to minimize or even prevent any waste disposal to the environment. In this case the contractor is demanded to make or provide solid construction waste containers and labor. Non-degradable waste are to be collected in certain places and later disposed to the dump site with the assistance of the local government.

2.1.2. Technology toRepairRoad

Before conducting mobility activities of heavy equipment to transport drilling equipment and material, PT. PERTAMINA EP-PPGM in association with local government institutions will conduct a road survey to ensure the class, condition and stability of the roads that will be passed by the heavy vehicles. Roads/bridges with insufficient conditions will be repaired in order to adjust to the vehicle weight. For example the Batui River bridge and other small bridges on the way to the drilling area. This is an effort to prevent road damages. If damages occur on roads/bridges caused by the activities of the PT. PERTAMINA EP-PPGM, the damaged roads/bridges will be rebuilt to the initial conditions.

2.1.3 Technology of Pipe Installation in River Crossing Area

Land pipes that cross rivers and roads will be installed using horizontal directional drilling system. The distance of the pipe ends to the river bank is around 100-150 m. The pipe will be planted in the bottom of the river around 2 m deep depending on the condition of the material in the river base. With a 26” inch pipe diameter, 0,456” inch pipe thickness with an outer casing, the risk of leaking is expected to be minimum. To protect pipes from internal and external corrosion, chemical inhibitor and cathodic protection systems are assembled.

With these systems, the environmental impacts in river water and traffic disturbance can be avoided. The horizontal drilling system is presented in figure 2.3.

2.1.4 Pipe Leak Detecting Technology

To detect any leaks on pipes during operation, a normal method will be conducted using instrumentations that can monitor flow pressure and temperature, through the leak detection system that interconnects with the SCADA (Supervisory Control and Data Acquisition) system. The operator will observe this condition, therefore when abnormal fluctuations occur in gas flow, it will immediately be investigated to confirm any leaks.

(19)

EMPMatindok Gas Development Project _II-11 2.1.5 Noise and emission control

Noise produced during the GPF operational activities could come from the gas compressor, power plant, and other instruments. Technically, noise control are conducted as follows:

• Controlling the distance of the location of the facilities with the nearestsettlement.

• Maximizing the use of lower noise emission equipments.

• Building housings that can suppress noise coming from certain noisy instruments. • Using silencers in exhaust channels of combustion engines and gas turbines. • Installing acoustic insulations in chimneys and pipes.

• Planting noise absorbing plants.

2.1.6 Handling of Used Chemicals

The management of chemical materials are as follows:

• Adjusting orders of chemicals with the needs of processes to avoid large amounts of remainders.

• Each chemical substance order must have MSDS (Material Safety Data Sheet)

• Procedures for handling, collecting, processing and stocking up used chemicals must be in accordance to the requirements written in Regulation of Head of BAPEDAL No. Kep-01/BAPEDAL/09/1995 to Kep-05/BAPEDAL/09/1995 and in the Government Regulation (PP) No. 18 of 1999 jo PP No. 85 of 1999, regarding the Waste Management of Hazardous and Toxic Substances along with the technical guidelines.

(20)

EMPMatindok Gas Development Project _II-12 2.2 ECONOMICAL APPROACH

In environmental management, the project proponent will work together with government institutions and other related parties to overcome social, economical and cultural impacts caused by the activities of the Matindok Gas Development Project. The form of this cooperation are as follows:

1. Reducing import tariffs for environmental management equipments. For example: oil separator, gas scrubber, gas filter, incinerator, silencer, desulphurization, etc.

2. Process of Land acquisition refers to the government laws and regulations, especially PP No. 36 of 2005 on Providing Land for public development.
