Executive SummaryEnvironmental ConcernsMitigation Measureswill be regularly maintained to ensure that the pollutionemission levels conform to the SPCB norms.During operation by improving intersections; by removingtraffic bottlenecks; by maintaining a steady stream flow oftrafficLocationsNoisePollutionIncrease in noise due toconstruction activity butwould be for short termDuring operation period dueto increase in trafficThe plants and equipment used in construction will strictlyconform to the GoI noise standards.All vehicles and equipment used in construction will be fittedwith exhaust silencers. The noise from the equipment mustcomply with the relevant legislation for levels of soundemission.Workers in vicinity of loud noise, and workers working with orin crushing, compaction, concrete mixing operation will wearearplugs.All activities pertaining to procurement, storage, transport andhandling of explosives and subsequent blasting will be carriedout as per the statutory Indian Explosives Act 1984.
