In recognition of our impacts, mainly dust and noise, to the surrounding area, the environmental management at our operations focuses on the isolation of the emissions at their sources. The combined effect from our fully enclosed production lines, the dust extracting and filtering system, and other dust suppression measures that we installed at each emission source point allowed us to meet the most stringent air quality standards. Our Noise Pollution Control Plan which put together selection of low noise level machinery, isolation of noise source, prevent maintenance measures, and other administrative control ensures the Acceptable Noise Levels suggested by the Environmental Protection Department and other legal requirements can be met.
We put in place environmental monitoring programs to ensure the emissions will be minimal and not harm the surrounding environment. Our Noise Monitoring Program covers 100% of our work sites, monitors the noise levels at the sensitive receivers. While the Air Quality Monitoring provides accurate data for evaluating the effectiveness of the dust pollution control measures we have in our work sites. We also monitor the water quality at the discharge points in our quarry sites protect the water body from being polluted.
