๐Ÿ”† CAQM Mandates Cleaner Light Goods Vehicles in Delhi-NCR, Tightens Stone Crushing Dust Rules

๐Ÿ“ Why in News?
โœ… The Commission for Air Quality Management (CAQM), in its 29th Full Commission Meeting (18 August 2026), approved Direction No. 102 and Direction No. 103 to strengthen air-pollution control in Delhi-NCR.
โœ… Direction 102: Phased transition of Light Goods Vehicles (LGVs) towards cleaner technologies.
โœ… Direction 103: Technology-enabled monitoring and stricter dust-control measures for stone crushing units.

๐Ÿ“ CAQM: Key Facts
โœ… Established under the Commission for Air Quality Management in NCR and Adjoining Areas Act, 2021.
โœ… Replaced the Environment Pollution (Prevention and Control) Authority (EPCA).
โœ… Jurisdiction: Delhi, Haryana, Rajasthan, Uttar Pradesh and Punjab.
โœ… Its directions override those of CPCB and SPCBs within its jurisdiction, subject to the Supreme Court.
โœ… GRAP serves as its emergency response framework for tackling deteriorating air quality.

๐Ÿ“ Direction No. 102 โ€” Cleaner LGVs

N1 LGVs | GVW โ‰ค 3.5 tonnes
โœ… Delhi: From 1 January 2027
โœ… High Vehicle Density districts โ€” Gurugram, Faridabad, Sonipat, Ghaziabad & Gautam Buddha Nagar: 1 July 2027
โœ… Remaining NCR districts: 1 January 2028

N2 LGVs | GVW 3.5โ€“12 tonnes
โœ… Delhi: From 1 January 2028
โœ… HVD districts: 1 July 2028
โœ… Remaining NCR: 1 January 2029

โžก๏ธ Cleaner modes include electric vehicles, hydrogen fuel-cell vehicles and other approved zero/low-emission technologies.

๐Ÿ“ Direction No. 103 โ€” Stone Crushing Units
โœ… CPCBโ€™s Environmental Guidelines for Stone Crushing Units, 2023 to be incorporated into Consent to Operate (CTO) conditions.
โœ… Mandatory continuous PM2.5/PM10 monitoring and video surveillance.
โœ… Wheel-washing systems at exits to prevent dust from being carried onto roads.
โœ… Units facing closure must submit corrective evidence and a notarised affidavit before resumption.
โœ… SPCBs/DPCC must verify compliance and recover Environmental Compensation (EC).
โœ… CAQM Flying Squads can conduct random inspections; violations can lead to fresh closure.

๐Ÿ“ Other Key Decisions
โœ… GRAP Stage-I: Invoked 19 May 2026 and revoked 29 May 2026 โ€” remained active for 11 days.
โœ… 6 thermal power plants penalised โ‚น61.85 crore for failing biomass co-firing targets in 2024-25.
โœ… Direction 65: Alternate-fuel relaxation extended till 13 September 2026 amid West Asia energy-supply disruptions.
โœ… Plantation target for 2026-27: 4.61 crore; 2.53 crore achieved by 4 August 2026.
โœ… 1,816 units cumulatively issued closure orders; 1,461 considered for resumption after compliance.
โœ… โ‚น3.26 crore approved for 4 air-quality research projects.

๐Ÿ“ Air Quality Governance โ€” Key Laws
โœ… Environment (Protection) Act, 1986 โ€” umbrella environmental legislation; Section 5 enables binding directions.
โœ… Air (Prevention and Control of Pollution) Act, 1981 โ€” legal framework for air-pollution control and CPCB/SPCBs.
โœ… NAAQS โ€” standards for permissible concentrations of major air pollutants.
โœ… NCAP, 2019 โ€” national programme targeting reduction in particulate pollution in non-attainment cities.
โœ… BS-VI norms โ€” Indiaโ€™s current stringent vehicle-emission standards.

๐Ÿ“ GRAP: Four Stages

๐Ÿ”น Stage I: Poor โ€” 201โ€“300 AQI
๐Ÿ”น Stage II: Very Poor โ€” 301โ€“400 AQI
๐Ÿ”น Stage III: Severe โ€” 401โ€“450 AQI
๐Ÿ”น Stage IV: Severe+ โ€” >450 AQI

๐Ÿ“ Key Challenge
โœ… Delhi-NCRโ€™s pollution problem is structural and multi-sectoral, involving transport emissions, road/construction dust, industries, biomass burning and other regional sources.
โœ… Emergency measures such as GRAP can address pollution episodes, but sustained improvement requires source-specific, coordinated and year-round interventions.

๐Ÿ“ UPSC Mains Question
๐Ÿ”น โ€œDelhi-NCRโ€™s persistent air pollution reflects not merely an emergency-response challenge but a structural governance problem.โ€ Critically examine the institutional design of CAQM and evaluate the effectiveness and limitations of GRAP in achieving sustained improvement in air quality.

๐Ÿ”† MQ-9B Sea Guardian: India Leases HALE Maritime Drones

๐Ÿ“ Why in News?
โœ… India has contracted to lease 2 MQ-9B Sea Guardian HALE RPAS for the Indian Navy for โ‚น1,943 crore.
โœ… The 30-month lease aims to strengthen Maritime Domain Awareness (MDA) and persistent surveillance across the Indian Ocean Region (IOR).
โœ… Contract signed on 17 August 2026 in New Delhi with General Atomics Aeronautical Systems Inc. (GA-ASI), USA.

๐Ÿ“ MQ-9B Sea Guardian โ€“ Key Features
โœ… Class: High-Altitude Long-Endurance (HALE) RPAS
โœ… Endurance: 35+ hours of surveillance
โœ… Operating altitude: Typically 40,000โ€“50,000 ft
โœ… Primary role: Intelligence, Surveillance & Reconnaissance (ISR)
โœ… Sensors: Maritime surface-search radar, EO/IR, AIS receiver and optional sonobuoys.
โœ… Weapons: No weapons under the present lease.
โœ… SeaGuardian vs SkyGuardian: SeaGuardian is optimised for maritime surveillance, while SkyGuardian is primarily oriented towards land surveillance.

๐Ÿ“ Why HALE Drones Matter for India?
โœ… Enable persistent surveillance over large maritime areas without the endurance limitations of manned aircraft.
โœ… Complement the Navyโ€™s P-8I Poseidon maritime patrol aircraft.
โœ… Strengthen monitoring of strategic chokepoints such as:
โ†’ Strait of Hormuz
โ†’ Bab-el-Mandeb
โ†’ Strait of Malacca
โœ… Support Indiaโ€™s Maritime Domain Awareness and SAGAR vision in the IOR.

๐Ÿ“ Indiaโ€“US Defence Cooperation
โœ… LEMOA โ€“ 2016
โœ… COMCASA โ€“ 2018
โœ… BECA โ€“ 2020
โœ… BECA facilitates exchange of geospatial intelligence, improving navigation and precision applications.

๐Ÿ“ Indiaโ€™s MQ-9B Journey
โœ… India previously leased MQ-9B platforms during 2020โ€“22, giving the armed forces operational experience.
โœ… This experience contributed to Indiaโ€™s subsequent decision to pursue acquisition of 31 MQ-9B aircraft.
โœ… Indiaโ€™s indigenous TAPAS-BH (MALE) programme remains under development, while a deployment-ready indigenous HALE capability is still absent.

๐Ÿ“ Strategic Significance
โœ… Persistent MDA: Enhances Indiaโ€™s ability to monitor movements across the vast IOR.
โœ… Rapid capability: Leasing provides an immediate capability while indigenous systems and long-term procurement mature.
โœ… Blue-water surveillance: Particularly useful for tracking surface vessels and supporting wider maritime security operations.
โœ… Net Security Provider: Strengthens Indiaโ€™s ability to contribute to security and stability in the IOR.

๐Ÿ”† Chlorpheniramine + Phenylephrine Combination

๐Ÿ“ Why in News?
๐ŸŸข The Union Health Ministry has tightened rules for Fixed-Dose Combinations (FDCs) containing chlorpheniramine maleate and phenylephrine.
๐ŸŸข Labels must now carry a warning against their use in children below 4 years.

๐Ÿ“ What is this Combination?
๐ŸŸข It is an FDC commonly available as oral drops, syrups and tablets for symptomatic relief from common cold, allergic rhinitis and nasal congestion.
๐ŸŸข It combines an antihistamine with a nasal decongestant.

๐Ÿ“ Chlorpheniramine Maleate
๐ŸŸข A first-generation antihistamine that blocks H1 histamine receptors.
๐ŸŸข Helps relieve sneezing, runny nose and watery eyes.
๐ŸŸข Can cross the blood-brain barrier and cause drowsiness/sedation.

๐Ÿ“ Phenylephrine Hydrochloride
๐ŸŸข A sympathomimetic decongestant.
๐ŸŸข Causes vasoconstriction of blood vessels in the nasal passages, helping reduce nasal congestion.
๐ŸŸข Systemic effects may include increased blood pressure and heart rate.

๐Ÿ“ Why Restricted Below 4 Years?
๐ŸŸข Immature metabolism: Developing liver and kidney functions can increase the risk of drug accumulation and toxicity.
๐ŸŸข Serious adverse effects: Young children may be vulnerable to tachycardia, convulsions and paradoxical excitation.
๐ŸŸข Overdose risk: Multiple cough-and-cold products may contain the same active ingredients, increasing the risk of accidental double dosing.
๐ŸŸข Safer alternatives: Common viral colds are generally self-limiting; measures such as saline nasal drops and adequate hydration are preferred for young children.

๐Ÿ“ Prelims Focus
๐ŸŸข Chlorpheniramine โ†’ H1 antihistamine โ†’ Allergy symptoms
๐ŸŸข Phenylephrine โ†’ Vasoconstrictor โ†’ Nasal decongestion
๐ŸŸข FDC โ†’ Two or more active pharmaceutical ingredients in a fixed ratio
๐ŸŸข Restriction โ†’ Warning for children below 4 years
