Environment - Air pollution

Environment - Air pollution

Environment includes water, air, land, living organisms and their inter relationship between them.
Environment can be divided in to two components:
1.     Abiotic
2.     Biotic
Environmental impacts due to the construction and related activities
v  Air pollution
v  Water pollution
v  Noise pollution
v  Impact due to the solid disposal

Air pollution:

The main sources of air pollution and dust generation is due to the following factors
v Vehicular movement
v Operation of the stone crushers
v Loading and unloading activities at the material storage area
Drilling and blasting operation a  part from the above, Sources of air pollution includes gaseous emission generated from;
v Vehicle, plant and machineries operation
v Bitumen / asphalt operations
v Fuel wood burning for cooking at the labour camps and other applications
v Paint application, fuel storage areas as volatile organic compounds

Control Measures:

Dust Control Measures:
v Periodic sprinkling of water
v Vegetative cover
v Wind breaks barrier
v Mulch / hydro seeding

Administration control measures:

v Speed limit for all project vehicle in construction site shall be 20 km/hr
v Enclosed conveyor belts
v Plantation of dust screening vegetation around polluting units
v Conduct “AIR MONITORING” at least once in every six months and compare the results
with National Ambient Air Quality Standards (NAAQS)

Engineering control measures:

v Bag filters / cyclones and other Air pollution control screens to entrap suspended particulate matter
v Periodic cleaning of the dust filtering equipment’s
v Low sulphur content diesel shall be used, if available in the local market
v 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;
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 in͟
