Re: 10% of oil slick left at Phrao Bay (PM / MCOT Saturday, 03 August 2013) – It’s easy to say the pipe leaked, but what is really needed is to find out the root cause. Was this human error? Lack of training? Did someone open the wrong valve? Please try to get to the root cause. Any pollution must have solution to ensure this does not happen again. More questions on safety needed. Was the pipe old? Was there a lack of maintenance? With the world press watching for the truth, please don’t let the oil company brush the cause under the carpet. This can and will happen again. If nothing is found wrong then suspect human error. So please publish the real investigation facts.
