India is third largest coal producing country in the world. It will have to enhance the production to fulfill the future deman. Due to large amount of mining operation, industrial activities, such as national Thermal Power Plant. Chhattisgarh State Electricity Board, Coal handling plant, BALCO, produces environmental. In the first approach (NAAQS dependant) air quality indexing was evaluated with the assumption of equal importance to all the pollutants, Initially quality rating for each pollutant was calculated on the basis of observed and permissible standards values (the standard being assumed as reference baseline for each pollutant). The geometric mean of quality rating of all the pollutants was evaluated to derive quality index for air at all the monitoring locations. As per the derived index, T.P. Nagar and Bhilai Basti locations are highly polluted whereas Jhargra village is the least polluted location. The remaining locations are moderately polluted. Air quality depreciation indexing, on the other hand, is NAAQS independent and based on value function curves. The average values of the pollutants were taken for calculation of air quality depreciation index for Korba industrial belt. The air quality depreciation indexes for all the locations are indicating substantial deterioration of air quality of Korba industrial belt. T.P. Nagar location has the maximum depreciation from the desired air quality followed by Bhilai Basti. The results indicate the Jhagrha village has observed least deterioration followed by Pump House colony. The air quality depreciation in the down wind direction of thermal power plants at a distance of 4-5 km in Pump House colony is less as compared to the places nearer to the industries, like Bhilai Basti, manikpur colony, FCI and Kusmunda colony. Hence impact of coal mining and thermal power plant is being felt in these residential areas. T.T. Nagar, Korba town and Kusmunda Colony have shown significant degradation due to miscellaneous vehicular traffic, that is industrial vehicles and personal vehicles.
