BACNOTAN, La Union: The Philippine Coast Guard would conduct an investigation on the large dredging machine pipe which was swept by strong waves by Typhoon Ineng, ending up in Barangay Baroro, Bacnotan town. “There is still no confirmation if where it really came from and why was that big pipe here,” said Ensign Simeon Dela Rosa, Coast Guard operations officer. He said that so far, there is no evidence yet that the pipe is hazardous and that there is no trace of oil.
