The Environmental and Social Impact Assessment (ESIA) considers the potential environmental and social impacts of the project based on extensive technical investigations has been prepared to meet the requirements of the Equator Principles and underlying International Finance Corporation (IFC) Performance Standards for the construction and operation of a coal fired power station by PT Cirebon Electric Power (PT CEP) to be developed at a site located in the Kanci Area near Cirebon City. The plant will consist of 1 x net capacity of 660 MWe coal fired power system having one steam generator, one steam turbine and associated equipment and facilities. The Assessment also provides information on the institutional and regulatory framework for the assessment, the site selection process, an assessment of alternative technologies considered for the project and a description of the existing environment including the socio-economic context.
The ESIA and the associated Action Plan set out mitigation and monitoring actions that address the key environmental and social impacts identified in the analysis. The Implementation of the Action Plan in the broader context of an environmental management system for each phase of the project will ensure that environmental and social impacts of the project will be no more than minor. The assessment of potential impacts and the resulting mitigation and monitoring actions also meet the requirements of the Equator Principles and IFC Performance Standards.
The Environmental Action Plan sets out mitigation actions includes:
- Air Discharges - A range of measures to mitigate the impact on air quality from the operation of the power plant. Theses include:
- Low NOx tangential burners to reduce Nox emissions.
- Four section Electrostatic Precipitator to control particulate emissions below 40mg/Nm3 at 3% O2.
- The use of bag filter units to reduce dust emissions from buildings where dusty operations such as the crushing and screening of coal and the pneumatic conveying of pulverised coal and fly ash.
- All conveyors are covered and transfer points fitted with dust suppression sprays.
- The use of an Environmental Grab type ship unloader for unloading coals from the barges.
- The provisions and use of dust suppressions water sprays in the coal stockpile area and ash pond.
- The burning of low sulphur coal (less than 0.2%) coupled with a high chimney (215m).
- Greenhouse Gas Emissions - PT CEP will implement a greenhouse gas inventory and management system including targets for reducing the greenhouse gas emissions intensity of the power plant operation.
- Discharges to the Marine Environment - The wastewater treatment system will treat all waste discharges to the relevant standard prior to discharges, in many cases meaning the discharge water is of better quality than the receiving environment. The use and storage of hazardous substances and other potential marine contaminants will be carefully managed through the implementation of an Environment Management System. Coal dust wil be managed through the enclosure of the barge unloading and conveying system as well as the use of water sprays on the coal stockpiles.
- Mangrove Management - PT CEP will initiate a Mangrove enhancement project in the Cirebon area to mitigate the impacts of the power plant development on the immediate area.
- Noise Management - In order to reduce the night time noise level, PT CEP will specify low noise equipment and install enclosure around equipment to reduce noise from the power plant operation.
- Waste Disposal - PT CEP will endeavour to minimise the amount ot waste generated by the power plant operation. Where waste is generated PT CEP will seek to identify reuse or recycling options., for example using fly ash in cement manufacture. Where no viable reuse or recycling options are available waste will be disposed of at appropriately licensed facilities. A Waste Management Plan will be developed for the site.
- PT CEP will report on greenhouse gas emissions associated with the operation of the power plant and seek to reduce the carbon intensity of the power produced where economically and technically feasible to do so.
- Flooding - A stopbank will be constructed on the true left bank of the Kanci river to reduce the adverse flooding effect of the constuction of the platform to the rivers west. Emergency response such as refuges and flood warning system will also be installed as part of a flood management plan to mitigate increased flooding potential to the east of the river.
- Community Liaison - The Communications Management Plan developed during the construction phase will be amended to reflect the communications requirements for the operational power plant and actively implemented.
- Health and Safely - The health and safely of power plant staff will be protected by the implementation of the health and safely management policy of PT CEP.
- Hazardous substances - Hazardous substances will be managed under the framework set by the site Environment Management System and PT CEP's hazardous substances management policy.
- Host Community impacts - A range of mitigation actions are proposed to address the socioeconomic impacts of the project. PT CEP will develop a Stakeholder Management Plan to coordinate interactions with key local stakeholders. This plan will have a different emphasis for different phases of the project. Key policies will also be developed covering a range of issues including grievance mechanism, preferential employment for local people, re-training for local people and providing alternatives to subsistence agriculture lifestyle currently predominant in the area.
- Migrant Worker Impacts - PT CEP will also work with migrant workers, and in particular those from outside Indonesia, to ensure they are aware of local cultural norms. Where possible migrant works will be encouraged to bring their families.
