The Commission for Air Quality Management (CAQM) has said that measures under ‘Stage-1’ of the Graded Response Action Plan (GRAP) will be enforced in the NCR with immediate effect.


What is GRAP?

  • Approved by the Supreme Court in 2016, the plan was formulated after several meetings that the Environment Pollution (Prevention and Control) Authority (EPCA) held with state government representatives and experts. The result was a plan that institutionalised measures to be taken when air quality deteriorates.
  • GRAP works only as an emergency measure. As such, the plan does not include action by various state governments to be taken throughout the year to tackle industrial, vehicular and combustion emissions.
  • The plan is incremental in nature — therefore, when the air quality moves from Poorto Very Poor’, the measures listed under both sections have to be followed.


Background –

  • GRAP has been successful in doing two things that had not been done before — creating a step-by-step plan for the entire Delhi-NCR region, and getting on board several agencies: all pollution control boards, industrial area authorities, municipal corporations, regional officials of the India Meteorological Department, and others.
  • The plan requires action and coordination among 13 different agencies in Delhi, Uttar Pradesh, Haryana and Rajasthan (NCR areas). At the head of the table is the EPCA, mandated by the Supreme Court.
  • GRAP was notified in 2017 by the Centre and draws its authority from this notification. Before the imposition of any measures, EPCA holds a meeting with representatives from all NCR states, and a call is taken on which actions have to be made applicable in which town.


Steps in GRAP –

  • When GRAP comes into force, diesel generator (DG) sets are no longer to be used in Delhi and the NCR towns of Noida, Ghaziabad, Greater Noida, Faridabad, and Gurgaon. The only exception is DG sets used for emergency and essential services.
  • Pollution control authorities begin night patrolling to check for dust and industrial emissions, as well as the burning of waste. Mechanised sweeping and frequent sprinkling of water on roads (to make the dust settle) have been directed.
  • These steps will be incremental. Levels of pollution are expected to rise as winter approaches — and as they do, more measures will come into force, depending on the air quality.
  • If air quality reaches the ‘Severe+stage, the response under GRAP includes extreme measures such as shutting down schools and implementing the odd-even road-space rationing scheme.


Achievements of GRAP –

Three major policy decisions that can be credited to EPCA and GRAP are the closure of the thermal power plant at Badarpur, bringing BS-VI fuel to Delhi before the deadline set initially, and the ban on Pet coke as a fuel in Delhi-NCR.
