Environment, Social and Health Impact Assessment

IRPC and IRPC Group’s affiliate have been conducting social, environmental and health impact studies for all projects which are within scope as part of the process to prepare the EIA reports, which are required by law and which must be prepared in compliance with the criteria, methodology, regulations and guidelines for EIA report preparation under the Notification of the Ministry of Natural Resources and Environment and other relevant laws.

There are 9 projects, which have been approved by a committee of experts, the Office of Natural Resources and Environmental Policy and Planning. 8 of which had to prepare EIA, while one project had to submit EHIA.

In 2017, IRPC did not have any new project development that required public participation. However, for 2018, IRPC has planned to conduct this process to gather inputs on Paraxylene production plant development. IRPC will continue to exceed our designated management approach to strengthen community trust in our ability to live and sustainably develop together. For more information, please see and
