GRAP Stage 1 in Delhi-NCR: What It Means and What Restrictions Apply

The Commission for Air Quality Management (CAQM) invoked Stage I of the Graded Response Action Plan (GRAP) across Delhi-NCR on Wednesday, October 21, 2026, after Delhi's Air Quality Index (AQI) climbed to 244 by 2 pm, pushing the city firmly into the "Poor" category. In practical terms, Stage I means tighter dust control at construction sites, mandatory mechanised road sweeping, a ban on coal and firewood in restaurant tandoors, and restrictions on diesel generator use across the capital region — not a lockdown, but the first rung of a four-stage pollution response that tends to escalate through November.

What pushed Delhi into GRAP Stage I today

Delhi's AQI had been sitting at 179 ("Moderate") on October 20, according to CAQM figures reported by Business Today. By 10 am on October 21, CPCB data showed it at 238, and by the 2 pm reading used for the CAQM order, it had risen to 244. Delhi Minister Manjinder Singh Sirsa said mechanical road sweepers must now cover "100% of roads from today." At the station level, Jahangirpuri recorded an AQI of 308 and Pusa 314 — both in the "Very Poor" band — while around 16 of the city's monitoring stations, including Anand Vihar, were still reading "Moderate," underlining how patchy pollution levels are across the city even on a single "Poor" day. Both the India Meteorological Department and the Indian Institute of Tropical Meteorology have forecast that air quality will likely stay in the poor range over the coming days, which is why the order covers all of NCR — not just Delhi — including adjoining districts in Haryana, Uttar Pradesh and Rajasthan.

What actually changes under Stage I

GRAP Stage I is triggered whenever the AQI sits between 201 and 300 on the CPCB's scale (0-50 Good, 51-100 Satisfactory, 101-200 Moderate, 201-300 Poor, 301-400 Very Poor, 401-500 Severe). The measures agencies and businesses must now follow include:

• Intensified mechanised road sweeping and water sprinkling on major roads
• Stricter dust-control compliance at construction and demolition sites
• A ban on coal or firewood in tandoors at hotels, restaurants and open eateries, who must switch to electricity or cleaner fuel
• Restrictions on diesel generator sets, with exceptions for emergency and essential services and regulated industrial use
• A crackdown on open burning of waste and tighter checks on vehicle emissions

For residents, CAQM's Stage I citizen charter — unchanged in substance from previous years — asks people to keep engines tuned, maintain correct tyre pressure, keep Pollution Under Control (PUC) certificates current, switch off engines rather than idle at red lights, avoid dumping garbage in the open, and report violations through the 311 app, Green Delhi app or SAMEER app.

The quieter change: GRAP itself got tighter this year

What most coverage of today's order has left out is that the GRAP rulebook residents are now living under isn't the same one from last winter. On September 29, 2026, CAQM — under chairperson Rajesh Verma — approved a revised GRAP schedule for NCR, consolidating several previously repeated dust, waste and transport measures directly into Stage I. The revised plan now runs 25 actions under Stage I, 8 under Stage II, 10 under Stage III and 5 under Stage IV. The revision also widened the geography of vehicle curbs: restrictions on BS-III petrol and BS-IV diesel (or older) light motor vehicles, previously limited to the high-density districts of Gurugram, Faridabad, Ghaziabad and Gautam Budh Nagar, now extend to Sonipat as well. Stage III of the revised schedule separately spells out entry curbs into Delhi for diesel-run BS-IV and below light and medium goods vehicles registered outside the capital. CAQM also flagged enforcement muscle behind the rules, noting more than 1,800 violating industrial and commercial units have already received closure orders this year.

What it means for you

If you live in Delhi-NCR, Stage I by itself won't change your commute or shut anything down — it's a compliance and enforcement stage aimed at construction firms, restaurants and civic agencies rather than individual households. But three things are worth acting on now. First, if your vehicle's PUC certificate has lapsed, renew it: enforcement checks typically tighten the moment any GRAP stage is active, and Delhi has separately linked fuel sales to valid PUC certificates this year. Second, if you run a restaurant, dhaba or catering business using tandoors, coal or firewood use is banned with immediate effect, not from a future date — switching to an electric or gas tandoor now avoids a closure notice later. Third, pay attention to the AQI trend rather than today's number alone: IMD and IITM forecasts point to air quality staying poor through the week, and Diwali-season firecracker and crop-residue burning typically push Delhi from Stage I into Stage II ("Very Poor", AQI 301-400) within days, and sometimes further. Vulnerable groups — children, the elderly and anyone with respiratory or heart conditions — should start limiting prolonged outdoor activity now rather than waiting for a more severe stage to be declared, since CAQM's own pattern this year shows stages escalating fast once forecasts turn unfavourable.
