Approximately 500,000 liters of diesel spilled along the coastline of Cavite. The affected municipalities are Naic, Rosario, Tanza and Ternate. Petron owned the oil tanker who spilled the thousand liters of diesel. Many fishermen are being affected because of this incident. A huge volume of fishes were found dead and unsafe for human consumption, along the seashore of the four affected municipalities. The Bureau of Fisheries and Aquatic Resources, Department of Environment and Natural Resources, Philippine Coastguard, together with the LGU of Cavite are doing a wide and thorough investigation of the incident.
