Cirebon Coal Fired Power Plant (CFPP) was envisioned to be a steward in sustaining the environment and is committed to managing the aspects of its operation that may impact on the environment such as; water discharges, air emissions, noise disturbances, coal dust, ash dust and hazardous waste production.

The Cirebon CFPP chooses environmentally friendly technology methods to prevent environmental pollution and optimizes utilization of operational side products. Thereby, preserving the environment and contributing to further sustainable development.

Monthly, quarterly and bi-yearly monitoring is being implemented by independent certified laboratories to ensure all impacts are closely controlled and managed such as; waste water, ground water, residential well water, air emission and ambient air qualities.


Cirebon CFPP has been reporting the implementation of Environmental Management and Monitoring Plans in a bi-yearly report required by Government. Cirebon CFPP also reports implementation in other quarterly reports to comply with AMDAL (Environmental Impact Assessment).




II.1 Electrostatic Precipitator

The lectrostatic Precipitator manages emissions by trapping and removing fine fly ash in the flue gas up to 99.8% to prevent any contamination of ash fall. The effectiveness of electrostatic precipitator  is proven by the stack emission parameters. Total Particulate approx 25 mg/Nm3 of standard threshold 100 mg/Nm3 and opacity approx 10% of standard threshold20%.

Total particulate approximate is 25mg/Nm3 of standard threshold of 100mg/Nm3. Opacity approximate is 10% of the standard threshold of 20%.



II.2 Double Fly Ash Silo

The Double Fly ash silo has a total capacity of 1,300 Tonnes, providing sufficient fly ash temporary storage capacity prior to being transported to a cement factory. Therefore, fly ash land filling is not needed.



II.3 Temporary Ash Storage Pond

The Temporary Ash Storage Pond is only to be used in emergency cases when transportation by trucks to the cement factory is not allowed onhighways due to   Eid Holidays and/ or other fly ash silo troubles. Equipped with 1(one) monitoring well at the upstream, 2(two) monitoring wells at the downstream and 1(one) leak detection well, as well as a pit to collect and transfer the contaminated water into a waste water treatment plant. Temporary ash storage pond is permitted by Local Government Environmental Agency by issuing a Non Objection Letter.

II.4 Process Waste Water Treatment Plant

The Process Wastewater Treatment Plant will properly treat all waste water that is  generated during the power plant operation and maintenance process periods. Oily waste water can also be treated in this plant. Daily monitoring is conducted by a internal laboratory and mandatory monthly monitoring is conducted by an Independent Certified Laboratory.



II.5 Ash Wastewater Treatment Plant

The Ash Wastewater Treatment Plant is particularly designed to treat Fly Ash and Bottom Ash contaminated water at the Fly Ash and Bottom Ash Temporary Storage. The ash waste water treatment plant is mostly  unoperated due to no fly and bottom ash being dumped at the ash pond, therefore, there is no contaminated water. This plant is also used to treat coal run off contaminated water  in the event that  all coal settling ponds are not  capable of settling  down coal fine particles.



II.6 Coal Run off Settling Ponds

A series of coal run off settling ponds are utilised to settle down coal fine particles to meet 150 mg/l of the Total Suspended Solid standard threshold discharge as required by applicable regulations. In emergency conditions, in case the three series of coal run off settling ponds are not properly working, chemical treatment at the ash waste water treatment will be conducted to ensure no contamination of the surrounding environment.

II.7 Impermeable Membrane

High Density Poly Ethylene (HDPE) membrane is applied at the Coal Storage, Coal Run off Settling Pond and the Ash Temporary Storage Pond to prevent ground water and soil contamination. This membrane is like a strong  thick plastic sheet that can prevent any penetration of coal or ash contaminated water seeping into the ground.



II.8 Interceptor Pit

The Interceptor Pit is the final guard of storm water drainage prior to being discharged to the Sea.  Storm water drainage was separately designed with waste water drainage. The interceptor pit treats contaminated water by filtering and settling. Cirebon CFPP has implemented  double prevention by constructing the interceptor pit to ensure any coal and other contaminations in thestorm water drainage can be properly settled down and or transferred back into the waste water treatment plant.



II.9 Coal Storage Wind Breaker

The wind breaker facility of 12, 75 m high fences surrounds the coal storage. Coal dust spreading into the surrounding Cirebon CFPP can be minimised by this facility. Three layer of trees  are also planted to maximize the function of the wind break.



II.10 Water Sprinkling System

Pressurized water is sprayed  onto the coal storage to capture coal dust and to moisten the coal upper layer to minimize coal dust spreading  in windy seasons. In the dry season, the water sprinkling system is often implemented.



II.11 Coal Dust Sweeper and Vacuum Cleaner Truck

Cirebon CFPP has  implemented a coal dust sweeper and vacuum cleaner truck to mitigate any coal dust spillage along the coal jetty and other areas that might be unintentionally contaminated by coal dust.

II.12 Sewage Treatment Plant

The Sewage Treatment Plant treats all sanitary waste water by combining microbiology-physical treatment to ensure the sewage outlet meets the applicable regulations and does not  contaminate ground and surface water.



II.13 Stack height of 215 meters

The Stack height is 215 meters to discharge stack gases. This height is determined according to the International Finance Corporations “Good International Industrial Practice (GIIP)” and air dispersion modelling. The stack height will guarantee that the Highest Ground Level Concentration (HGLC) of stack gases at the certain area, comply with applicable regulation.



II.14 Cooling Tower

Cirebon CFPP is the first large coal fired power plant implementing a closed cycle cooling tower for power plant cooling. The benefit of this system is that no hot water is discharged into the sea. Several seas biotas such as plankton and benthos are sensitive to hot water. Therefore,  the Cirebon CFPP cooling system is more environmentally friendly than other large power plants with once through cooling systems.



II.15 Hazardous Waste Temporary Storage Building

The Hazardous Waste Temporary Storage building is constructed to temporarily store hazardous waste  for a maximum of 90 days as required by applicable regulations. Hazardous waste which is generated by power plant operation and maintenance such as used oil, used lamps, used cartridges, used resin, used membranes, used batteries, expired chemical, residual laboratory chemicals, contaminated rags, and contaminated glass wool shall be temporarily stored at the building prior to being disposed by a certified contractor.



II.16 Chemical Secondary Containment

All hazardous chemical tanks at the Cirebon CFPP are equipped with 110% capacity of concrete secondary containment. In emergency cases of hazardous chemical leakage, the secondary containment will detain chemical  therefore preventing the contamination of  the environment.

II.17 Green Belt Mangroves and Trees

Cirebon CFPP commits to protect and preserve mangroves in the surrounding areas. Mangrove planting and revegetation have been conducted since the commencement of the project construction in the middle of 2009. Trees are planted to enhance green and beautiful landscape as well as a noise barrier. These below pictures show the difference between before and after planting of mangroves and tress by Cirebon CFPP. Cirebon CFPP has supported mangroves planting by involving the community at several areas along Cirebon shoreline as one of our responsibilities to surrounding community. More than 15,000 trees and 20,000 mangroves have been planted.

III.2 Manual Sampling of Air Emission Quality Monitoring

An independent certified laboratory is scheduled quarterly  to conduct manual sampling at the emission stack. This manual sampling is intended to monitor several parameters such SO2, NO2, Total Particulate, opacity, temperature and flow rate. Cirebon CFPP has completed air emission monitoring not only using CEMS but also manual samplings.



III.3 Ambient Air Quality Monitoring Station

Cirebon CFPP has installed an Ambient Air Monitoring System that operates (24 hours a day, 7 days a week) since 2010 (construction phase) at the area that may have the Highest Ground Level Concentration (HGLC) based on air dispersion modeling to continuously monitor ambient air quality.

III.5 Ground Water Monitoring Well

The Ground Water Monitoring Well is constructed by Cirebon CFPP at the surrounding ash temporary storage to monitor existing ground water quality and the quality difference after power plant operation. Cirebon CFPP has not been dumping ash at the ash temporary storage, therefore the quality of ground water is not significantly  different.



III.6 Water Monitoring

Cirebon CFPP is regularly monitoring the sea water, river water, ground water and community well water 4 (four) times a year. An independent certified laboratory has been hired to conduct sampling and analysis. The laboratory test result will be arranged and compiled in an Implementation of Environmental Management and Monitoring Report.



III.7 Flood Early Warning System

Two flood early warning systems are installed at the upstream of Kanci River ( Buntet Village) and the downstream of Kanci River (Kanci Kemis Village) to monitor flood level and alert the community along Kanci River stream. The system has a water level sensor and will alert by siren, when the water level reaches the highest water level  predicted to flood some areas on the edge of Kanci River. Cirebon CFPP is in cooperation with Government (River Authority) to develop and monitor this system.
