The purpose of an AMDAL is to predict the significance of Project impacts on the existing (baseline) geo-physical, biological and socioeconomic, environment and public health and to identify measures to minimize negative impacts and maximize positive ones. In order to evaluate the Project from an environmental and social impact point of view, AMDAL documents were prepared to inform the decision-making by the Government of Indonesia.

The AMDAL study comprised of the following basic steps:

  • An integrated preliminary study was conducted taking into account environmental, socioeconomic and engineering considerations in order to select the most appropriate site for the Project. Ultimately, the expansion to the area adjacent to Unit 1-4 was selected.
  • The potential impacts of the Project were initially identified in the Scoping phase.
  • The existing baseline conditions, environmental or socio-economic sensitivities were determined through field work and local surveys (primary data) and review/collection of existing data (secondary data).
  • Stakeholders input were taken into account in order to identify and describe all impacts.
  • Modeling was used to predict specific impacts, such as thermal plume impact, air quality, noise, etc.;
  • After identification, description and scoring of all impacts, mitigation and monitoring measures were discussed and formalized with the objective of reducing the impacts to the lowest levels possible. Input from local residents and other stakeholders were taken into account in this phase as well.
  • Based on the identified mitigation and monitoring measures, an environmental and social management and monitoring plan (“RKL/RPL”) was developed in order to determine concrete actions, responsible party and monitoring schemes to guarantee satisfactory environmental and social performance during the Project activities.

Regarding the Project’s AMDAL process, after consultation with the local stakeholders, the KA-ANDAL (Terms of Reference or, in other words, the content of what and how needs to be studied in the environmental and social impact assessment, the ANDAL) was prepared and approved on September 11th 2015.

The AMDAL was approved on May 16th 2016 altogether with the RKL/RPL, through a Decree of Environmental Feasibility signed by the Governor of Java Province. The Environmental Permit was issued on the same day. Other permits will be obtained throughout the life of the Project as needed and in full compliance with Indonesian legislation requirements.
