* Operation of the stone crushers.

* Loading and unloading activities at the material storage area.

* Bag filters / cyclone and other Air pollution control screens to entrap suspend particular matter.

* Periodic cleaning of the dust filtering equipment's

* Low sulpher content diesel shall be used, if available in the local market.

* Low emission explosives



H = h + 0.2 Square root of KVA
 
Adequate stack height of DG set shall be maintained The minimum height of stack for DG shall be;
Where,
H = Total height of stack in meter
h = Height of the building in meter where the generator set is installed KVA = Total generator capacity
Reuse, Reduce, Recycle and make the earth a better place to live in
