CPCB NAAQS 2009 Compliant

Air Quality Dispersion Modelling & NAAQS Compliance for EIA

Gaussian plume dispersion model with NAQI/AQI calculator, CPCB standards comparison, and SPCB-ready air quality impact reports for Environmental Clearance applications.

NAAQS 2009

CPCB Ambient Air Quality Standards

Gaussian Plume

Briggs plume rise, Pasquill-Gifford classes

6 Pollutants

PM10, PM2.5, SO₂, NOₓ, CO, VOCs

Every Environmental Clearance application under the EIA Notification 2006 requires air quality impact assessment. This Gaussian plume model calculates ground-level concentrations from stack emissions, compares against CPCB NAAQS 2009, and generates the concentration-distance profile. Use for preliminary screening before commissioning full AERMOD/CALPUFF studies.
