Prakas No. 3591 on Project Classification for Environmental Impact Assessment.

This Prakas establishes a standardized classification system for development projects in Cambodia to determine the required level of environmental scrutiny. Projects are categorized into three tiers based on their potential impact on the environment and society: those requiring a Full Environmental Impact Assessment (FEIA), an Initial Environmental Impact Assessment (IEIA), or an Environmental Protection Contract (EPC). By providing clear criteria and a detailed appendix of project types—ranging from mining and energy to manufacturing and food processing—the regulation aims to guide project owners through the necessary legal procedures effectively while promoting sustainable development. The regulation also defines strict timelines for the Ministry of Environment to review and provide feedback on submitted documents.
