Delhi to Launch New Action Plan to Fight Air Pollution From October 1

New Delhi: A ‘finer’ Graded Response Action Plan — a set of anti-air pollution measures followed in the national capital and its vicinity according to the severity of the situation — will come into from October 1 and environment experts believe advance action this year will lead to lesser incidences of severe pollution. Earlier, GRAP would come into effect from October 15.Also Read – Around 30 Delhi Government School Principals To Begin Training With Cambridge University From Oct 10

The Commission for Air Quality Management (CAQM), a statutory body established in August 2021, for management of air quality in Delhi-NCR decided to implement GRAP early, considering suggestions from the public and experts that advance action can prevent drastic deterioration in air quality. Under the revised GRAP, curbs can be imposed on polluting activities up to three days in advance based on forecasts. Earlier, the authorities would implement the measures only after the PM2.5 and PM10 concentration touched a particular threshold. This time, restrictions will be based on air quality index (AQI) values rather than PM2.5 and PM10 concentration.

The green war room will monitor violations and redress complaints and grievances in keeping with the practice being followed for the last two years.

  1. GRAP has now been classified under four different stages of adverse air quality in Delhi: Stage I – ‘Poor’ (AQI 201-300); Stage II – ‘Very Poor’ (AQI 301-400); Stage III – ‘Severe’ (AQI 401-450); and Stage IV – ‘Severe Plus’ (AQI >450).
  2. Under Stage I, the CAQM has recommended strict action against polluting industries, vehicles and biomass burning.
  3. The use of coal and firewood, including in tandoors in hotels, restaurants, open eateries; and diesel generator sets, except for emergent and essential services, is banned under Stage II.
  4. If the situation turns “severe” (Stage III), authorities will have to enforce a ban on construction and demolition activities in NCR, except on essential projects (like railways, metros, airports, ISBTs, national security/defence-related projects of national importance) and non-polluting activities such as plumbing, carpentry, interior decoration and electrical works.
  5. Brick kilns, hot mix plants and stone crushers not operating on clean fuels, and mining and associated activities in NCR will also be banned under Stage III.
  6. State governments in Delhi-NCR may also impose restrictions on BS III petrol and BS IV diesel light motor vehicles (four wheelers) under Stage III.
  7. The measures to be followed in the “Severe Plus” category or Stage IV include a ban on the entry of trucks into Delhi, and on the plying of Delhi-registered diesel-run medium goods vehicles and heavy goods vehicles (HGVs) in the national capital except those carrying essential commodities.
  8. The use of four-wheeler diesel light motor vehicles, except for BS-VI vehicles and vehicles engaged in essential services, will also be banned in Delhi and the bordering districts of NCR.
  9. Stage IV will also entail a ban on industries running on dirty fuels and on construction and demolition activities in linear public projects such as highways, roads, flyovers, over bridges, power transmission and pipelines.
  10. State governments can consider allowing 50 per cent staff to work from home in public, municipal and private offices, and additional emergency measures like closure of educational institutions and the plying of vehicles on odd-even basis etc.
