Thailand’s national oil spill response plan is currently in its final draft stage and awaiting official endorsement. Despite pending approval, the country is already conducting exercises and operational activities based on the updated plan. Tier 1 spills continue to be managed under individual operator response plans. The revised national plan incorporates an Incident Management System (IMS) and outlines a dispersant policy governed by the Pollution Control Department (PCD), supported by the Gulf of Thailand subregional dispersant guidelines.
A formal NEBA/SIMA process has not yet been implemented. The draft plan recognizes in‑situ burning as a potential response option. Thailand has completed sensitivity mapping for most of its shoreline, and the updated draft also includes offshore response guidance, shoreline clean‑up frameworks, as well as oiled wildlife response and waste management plans.
