Ambient air quality of Chandigarh
Ambient air quality of Chandigarh is under pressure. Respirable Suspended Particulate Matter in the city is crossing its permissible limits. However, the SO2 & NOx levels are well within permissible limits. Due to its wider roads and wise traffic sense and regulations, traffic jams are rare in Chandigarh. In a survey, it is found that Chandigarh is the only city which is traffic congestion free. Whole of the Union Territory of Chandigarh is also declared as Air Pollution Control area in 1988. To abate industrial pollution, the industrial area has been located towards southeast of the city. The Railway Station is advantageously located bordering the industrial area. CPCC has made sure that all the air polluting industries have installed proper pollution control devices. To monitor and control vehicular pollution, 'Pollution under control' certificates have been made compulsory for all the vehicles by the State Transport Authority and Chandigarh Traffic Police. Thirty stations are authorized in the city to issue the same. While lead free petrol was introduced in the Union Territory in early 2000, efforts are being made to promote battery operated vehicles. The Administration has also shifted ISBT from sector 17 to Sector 43. This restricts the buses from outstations to the outskirts of Chandigarh. The Auto Repair Market has also been shifted from Sector 21 market to Sectors 43 & 48 at the outskirts. To strenthen the monitoring and control of air pollution further, burning of leaves & operation of unauthorized gensets is discouraged. Chandigarh Administration spreads awareness through mass media. From time to time camps and exhibitions to create awareness are also organized.
The entire Union Territory of Chandigarh was declared ‘Air Pollution Control Area’ under Air (Prevention & Control of Pollution) Act, 1981 on 1st, February 1988 and the Act was implemented by the Central Pollution Control Board (CPCB). Subsequently, the Chandigarh Pollution Control Committee (CPCC) was established in 1991 which is now responsible for performing the functions of the State Pollution Control Board.
