Graded Action Response Plan: Context


Graded Action Response Plan_3.1


Graded Action Response Plan: Key points

  • Curbs like bans on diesel generators and the use of coal-fired ovens should begin in Delhi and the National Capital Region (NCR) on October 15 irrespective of the air quality at the time.
  • Also, activities such as routine mechanised sweeping should also be initiated.
  • The committee also recommended that all ‘poor’ and some ‘very poor’ protocols of the Graded Response Action Plan (Grap) be activated.
  • It also recommended that some of the actions under the ‘very poor’ category should also commence from October 15, though the air quality index (AQI) is expected to remain in the ‘satisfactory’ to the ‘moderate’ category range in the NCR.

About Graded Action Response Plan

  • The Delhi Graded Response Action Plan is a set of emergency measures that was approved by the Supreme Court in 2016.
  • It comes into effect when the air quality index (AQI) in Delhi and the NCR breach certain thresholds.
  • The plan, as such, does not include action by various state governments to be taken throughout the year to tackle industrial, vehicular and combustion emissions.

GRAP: Two successes

  • It has created a step-by-step plan for the entire Delhi-NCR region.
  • It has brought on board several agencies: all pollution control boards, industrial area authorities, municipal corporations, regional officials of the India Meteorological Department, among others.

How has GRAP helped?

  • Fixed accountability: Executive actions to be taken under a particular air quality category are clearly marked.
    • Coordination among as many as 13 agencies from four states—Delhi, Uttar Pradesh, Haryana and Rajasthan—is simplified to a degree because of the clear demarcation of responsibilities.
  • Three major policy decisions:
    • closure of the thermal power plant at Badarpur
    • bringing BS-VI fuel to Delhi before the deadline set initially
    • ban on Pet coke as a fuel in Delhi-NCR.
  • The initial mandate of EPCA was to ensure that Delhi’s bus and auto fleet moves entirely to CNG — a mammoth task that played a crucial role in cleaning Delhi’s air in the late 2000s.
