Environment Secretary Roy Cimatu on Friday suspended two mining companies in Cebu that provided the crushed dolomite for the controversial Manila Bay “beach nourishment project” of the environment department after they allegedly destroyed corals in the waters near the mine site. Dolomite Mining Corp. (DMC) and Philippine Mining Service Corp. (PMSC), which processes quarried dolomite rocks, will remain suspended until an investigation by the Department of Environment and Natural Resources (DENR) is concluded. “I have to stop the operation while an investigation is conducted to determine whether or not the two companies violated some rules,” said Cimatu, who visited the dolomite mine site at Alcoy town in southern Cebu province.
