On recommendations of Philippine Coast Guard (PCG) commandant Vice Admiral Arthur N. Gosingan, Transportation and Communications Secretary Leandro P. Mendoza formed yesterday a national board of marine inquiry (BMI) to conduct a thorough fact-finding investigation on the oil spill off Guimaras Island in Western Visayas — so far the biggest ever reported environmental disaster in the country. In a press conference held at the PCG headquarters in Port Area, Manila, Gosingan said the creation of the national BMI elevated from a special board of marine inquiry (SBMI) the status of the probe body. Mendoza named Coast Guard deputy commandant Rear Admiral Danilo A. Abinoja as the national BMI chairman.
