- Emergency Response Mechanism: GRAP acts as an emergency response mechanism. It comes into play when the Air Quality Index (AQI) reaches “poor” levels.
- Four Stages: GRAP is divided into four stages, each corresponding to different levels of air quality:
- Stage 1: For AQI ranging between 201 and 300 (considered “poor”).
- Stage 2: For AQI of 301-400 (classified as “very poor”).
- Stage 3: For AQI of 401-500 (labeled as “severe”).
- Stage 4: The most severe stage, implemented when air quality levels reach extreme levels.
- Measures: Depending on the severity, GRAP enforces specific measures:
- Stage 1: Measures like restricting construction and demolition activities in certain plots.
- Stage 2: Additional restrictions to curb pollution.
- Stage 3: More stringent actions to protect public health.
- Stage 4: Emergency measures to tackle severe pollution.
- History: The Central Pollution Control Board (CPCB) proposed GRAP to address air pollution risks. It was approved by the Supreme Court and notified by the Ministry of Environment, Forests, and Climate Change in 2017.
- Implementation: The Environment Pollution (Prevention and Control) Authority (EPCA) oversees GRAP’s implementation. It coordinates with various agencies to combat air pollution in Delhi-NCR.
In summary, GRAP is a crucial plan that kicks into action when pollution levels rise, aiming to safeguard public health and improve air quality in the region.
