The Niuean ocean liner Yun Hai was grounded off the coast of Siaobaisha Islet of Penghu County in the early morning of 25 February. On that same day, the EPA kicked off its disaster relief measures in accordance with the Major Marine Oil Pollution Emergency Response Plan and dispatched authorized personnel to Penghu. An inter-ministerial coordination meeting was convened in which the status of the ocean liner was grasped in detail and possible anti-spillage measures were discussed. By means of continuous monitoring and a thorough survey of the coastal conditions, so far no marine pollution resulting from any oil leak has been reported. The EPA convened an inter-ministerial coordination meeting in the afternoon of 25 February. The meeting allowed the EPA to understand what equipment and capabilities each governmental unit has in dealing with the situation. The EPA, in turn, asked each unit to do what they are supposed to do, especially in regard to the removal of oil stocks on board the ship and the subsequent matter of hauling its hull. The Maritime and Port Bureau of the Ministry of Transportation and Communications was asked to get hold of the ship owner and its insurance company immediately. In addition, pursuant to Article 53 of the Commercial Port Law（商港法）, before the residual oil is pumped away from the stranded ship, or before the doubts of an oil leak can be completely lifted, the ship owner should provide sufficient financial guarantee and be requested to remove the oil stocks on board as soon as possible. In an effort to acquire more information about the ship, the EPA personnel spoke with the salvaged crew members. It emerged from their conversation that the ocean liner used diesel, not heavy oil. The Maritime and Port Bureau requested the ship owner to come up with a plan for the removal of the oil stocks and the ship itself. On 28 February, the relevant competent authorities did an on-site inspection of the wreckage. It was discovered that the hull of the ship was stranded on a reef area of Siaobaisha Islet. The body of the ship was still steady and showed no sign of significant tilt, while the ship was anchored on its port side. The waters surrounding the ship showed no signs of oil spill. The Maritime and Port Bureau requested the ship owner to commission a third party enterprise as soon as possible and, weather permitting to begin the work of the deployment of oil booms on 29 February.
