The extraction of dolomite rocks in the southern town of Alcoy in Cebu province has damaged the marine ecosystem in the area, according to the provincial government. An inspection conducted by the Provincial Environment and Natural Resources Office (PENRO) last week showed that corals within a 500-meter area of Barangay Pugalo’s waters were destroyed due to heavy siltation caused by crushed dolomite spilling into the sea during its transfer to bulk carrier vessels by conveyor belts. The PENRO survey was made following the transport of crushed dolomite from Alcoy for a “beach nourishment project” that was part of Manila Bay’s rehabilitation.
