CAQM invokes Stage-I of GRAP across Delhi-NCR as AQI enters ‘Poor’ category

1. At a Glance

• CAQM (Commission for Air Quality Management in NCR & Adjoining Areas) is the statutory body that operationalises the Graded Response Action Plan (GRAP) — an emergency, AQI-triggered tiered framework for Delhi-NCR air pollution control [S2][S3].
• Invocation of Stage-I signals entry of Delhi's daily-average AQI into the 'Poor' band (201–300); it activates a 27-point action plan binding on NCR State Govts., GNCTD, ULBs, and central agencies [S4][S5].
• High UPSC salience: intersects environmental governance, cooperative federalism, statutory bodies (Act of 2021 replacing EPCA), and pollution science (PM2.5/PM10, AQI methodology).

2. Why in the News

• On 19 May 2026, CAQM's Sub-Committee on GRAP invoked Stage-I with immediate effect after Delhi's daily-average AQI rose to 208 ('Poor') as per CPCB's daily bulletin [S1].
• IMD/IITM forecasts indicated AQI would persist in the 'Poor' band — uncommon for May, when AQI is typically 'Moderate'; pre-monsoon dust storms and stagnant winds cited [S1].

3. Background & Evolution

• 2016: GRAP first notified by MoEFCC on recommendations of EPCA (Bhure Lal Committee), following SC orders in M.C. Mehta v. Union of India [S3].
• 2020 (Oct): Commission for Air Quality Management Ordinance, promulgated; dissolved EPCA [S2].
• 13 Aug 2021: CAQM in NCR & Adjoining Areas Act, 2021 enacted by Parliament; permanent statutory body under MoEFCC; notification dated 23 April 2021 preceded the Act [S2].
• 2022: GRAP revised — shifted from reactive (post-event) to forecast-based pre-emptive invocation using IITM/IMD modelling [S3].
• 2024: Further tightened to a 27-point Stage-I plan, mandating dust control at construction sites, mechanised road sweeping, and stricter PUCC enforcement [S4][S5].

4. Core Static Facts

• Parent Ministry: Ministry of Environment, Forest and Climate Change (MoEFCC) [S2].
• Enabling Act: CAQM in NCR & Adjoining Areas Act, 2021 (No. 9 of 2021) [S2].
• HQ / Chair: Headquartered in Delhi; Chairperson appointed by Centre; total ~17 members incl. reps. of Punjab, Haryana, UP, Rajasthan, NCT-Delhi [S2].
• Geographic scope: Delhi + NCR districts + adjoining areas of Punjab, Haryana, UP, Rajasthan [S2].
• GRAP AQI bands (CPCB National AQI, 2014): 0-50 Good; 51-100 Satisfactory; 101-200 Moderate; 201-300 Poor (Stage-I); 301-400 Very Poor (Stage-II); 401-450 Severe (Stage-III); >450 Severe+ (Stage-IV) [S6].
• Stage-I (27-point) measures: ban on open waste burning, mechanical sweeping/water sprinkling, anti-smog guns at large construction sites (≥500 sq m), strict PUCC checks, diesel-genset regulation, anti-dust campaigns [S4].
• Penalties: Up to ₹1 crore fine and/or 5 years imprisonment for contravening CAQM directions (Sec. 14, CAQM Act, 2021) [S2].
• Sub-Committees: (a) Monitoring & Identification, (b) Safeguarding & Enforcement, (c) Sub-Committee on GRAP (invokes stages) [S2].

5. Multi-Dimensional Analysis

• Environmental: AQI of 208 in May is anomalous — driven by Rajasthan-origin dust, low wind speeds, biomass fires; PM10 dominant pollutant in summer vs. PM2.5 in winter [S1].
• Legal/Constitutional: CAQM Act overrides Air Act, 1981 and EPA, 1986 to the extent of inconsistency in NCR (Sec. 28); orders enforceable as decrees; appeals lie to NGT [S2].
• Administrative/Federalism: Centralised command structure with binding writ over four states + Delhi — addresses earlier coordination vacuum but raises subsidiarity concerns; states are members but Centre dominates appointments [S2].
• Scientific/Technological: Invocation now relies on IITM-Pune's Decision Support System (DSS) and SAFAR modelling to forecast AQI 3 days ahead — moves regime from reactive to anticipatory [S3].
• Ethical/Governance: Tension between livelihoods (construction labour, diesel-truckers) and right to clean air under Art. 21 (Subhash Kumar v. Bihar, 1991).

6. Recent Developments (last 12-18 months)

• 19 May 2026: Stage-I invoked at AQI 208 — first summer-period invocation cited in current PIB release [S1].
• 2026: CAQM's 28th Full Commission Meeting reviewed enforcement, dust mitigation, and EV transition agenda [S7].
• 2025: GRAP schedule revised to make Stage-III/IV invocation mandatory upon forecast (not post-event) [S3].
• Cumulative since inception: 78 directions & 11 advisories issued by CAQM [S2].

7. Prelims Hooks

• CAQM is a statutory body (not constitutional, not executive) under the 2021 Act [S2].
• CAQM replaced EPCA, which was constituted under Sec. 3(3) of Environment (Protection) Act, 1986 [S2].
• GRAP is invoked by the Sub-Committee on GRAP, not the full Commission [S1].
• National AQI launched by CPCB under MoEFCC in 2014 ("One Number-One Colour-One Description") [S6].
• Stage-I = 'Poor' (AQI 201-300); Stage-II = Very Poor (301-400); Stage-III = Severe (401-450); Stage-IV = Severe+ (>450) [S6].
• AQI on 19.05.2026 in Delhi: 208 [S1].
• Forecasting agencies feeding CAQM: IMD (MoES) and IITM-Pune (MoES) — not MoEFCC [S1].
• CPCB issues the Daily AQI Bulletin [S1].
• Penalty under CAQM Act: up to ₹1 crore / 5 yrs imprisonment [S2].
• NCAP (parallel programme, 2019): targets PM reduction in 131 non-attainment cities; 40% PM10 reduction by 2026 [S5].
• Appeals against CAQM orders → NGT [S2].
• CAQM jurisdiction: NCR + adjoining areas of Punjab, Haryana, UP, Rajasthan [S2].

8. Mains Relevance

• GS-III — Environment: Conservation, environmental pollution and degradation.
• GS-II — Governance: Statutory, regulatory bodies; centre-state coordination.
• Likely question stems: 1. "Critically examine the institutional design of the CAQM, 2021. Has it overcome the limitations of EPCA in mitigating NCR air pollution?" 2. "Discuss how the Graded Response Action Plan (GRAP) seeks to operationalise the precautionary principle in urban air-quality governance." 3. "Air pollution in Delhi-NCR is a problem of federalism as much as of science. Comment."

• CPCB & SPCBs under Air Act, 1981 — primary statutory regulators.
• EPCA (1998-2020) — predecessor body; legacy of SC monitoring.

10. Common Errors / Trap Areas

• CAQM is statutory, NOT constitutional; created by Parliamentary Act, not by notification alone [S2].
• GRAP is invoked by the Sub-Committee on GRAP — not by MoEFCC or CPCB directly [S1].
• IMD and IITM are under MoES, not MoEFCC — common confusion [S1].
• Stage-I corresponds to 'Poor', not 'Moderate' (a frequent MCQ trap) [S6].
• CAQM Act 2021 (Act No. 9 of 2021) — not 2020 (that was the Ordinance) [S2].
• NCAP target year is 2026 for 40% PM10 reduction (revised from 2024); base year FY 2017-18 [S5].
