Areas has issued the revised Graded Response Action Plan (GRAP) vide Order dated 21.11.2025, which categorizes adverse
air quality into four stages, namely Stage I (AQI 201–300), Stage II (AQI 301–400), Stage III (AQI 401–450) and Stage IV
(AQI >450);
And whereas the issue of air pollution in Delhi NCR is also being judicially monitored by Hon'ble Supreme Court
of India;
And whereas, an examination of the Air Quality Index (AQI) data for the last three years, i.e., 2023 - 24, 2024 - 25
and 2025 - 26, indicates that air quality generally starts deteriorating during the period from 1st November to 15th February
every year, wherein the median AQI ranges between 312 - 342, while the maximum AQI ranges between 461 – 494;
And whereas, for air pollution control during winter months, various directions/notifications / administrative orders
had been issued from time to time by GNCTD, including compliance with the orders of invoking of Graded Response Action

ANNEXURE 1
Guidelines for Installation of Anti-Smog Guns on High Rise Buildings
a. The mounting wheeled trailer shall be dispensed with, and the equipment shall be fitted on a simple bracket fixed
to the parapet wall of the high-rise building.
b. The aperture of the nozzle shall be 5 to 20 microns (instead of 30 to 50 microns) so as to effectively coagulate
dust particles contributing to 2.5 and 10 PM.
c. The throw distance (horizontal) should be 75 to 100 meters.
d. The consumption of water shall not exceed 1000-1200 litres/hour and 10000 litres in a day with 8 hours of
running.
e. The sound decibels due to use of air blower shall be reduced to minimum.
f. A suitable air quality monitor equipment should be integral to the overall system.
g. The size of the water droplets coming out of the nozzle should be further reduced to have a mist effect.
h. The equipment should be used intermittently during the periods of maximum pollution between 6:30 am to 9:30
am, 5:30 pm to 8:30 pm and 1:30 am to 4:30 am rather than running it throughout the day.
i. In addition, the equipment should preferably run in bursts of a few minutes between intermittent halt periods.
This will facilitate better coagulation of suspended impurities and will also reduce electricity and water
consumption.
j. Prescribed number of Anti-Smog Guns to be deployed on High -Rise Buildings in proportion to the built-up area
is given below:
Built up area | Number of Anti-Smog Guns to be deployed
Less than 10000 sqm | At least 03
10001-15000 sqm | At least 04
15001-20000 sqm | At least 05
20000-25000 sqm | At least 06
k. Thereafter for each 5000 sqm additional antismog gun would be installed.
l. Water used for Anti-Smog Guns should be treated water.
Annexure-2
