Air Pollution Control (Construction Dust) Regulation: ·
where breaking of rock/concrete is required, watering shall be
implemented to suppress dust generation, water spray shall be used during the
handling of excavated material at the site and at active cuts, tunnel
construction works, excavation and fill sites where dust is likely to be
created; ·
the heights from which excavated materials are dropped shall be
controlled to a minimum practical height to limit fugitive dust generation
from unloading; |
