GRAP - ENVIRONMENT

News: What is GRAP, Delhi-NCR’s action plan to combat rising air pollution?

What's in the news?

       With the Nation Capital Region’s air quality deteriorating to hazardous levels, the Commission for Air Quality Management (CAQM) on Thursday (November 3) invoked measures under Stage 4 of the Graded Response Action Plan (GRAP) with immediate effect.

Graded Response Action Plan:

       GRAP is a set of emergency measures that kick in to prevent further deterioration of air quality once it reaches a certain threshold.

       The GRAP was first notified in January 2017 by the Ministry of Environment, Forest and Climate Change. This was based on a plan that was submitted by the Central Pollution Control Board (CPCB) in November 2016.

Implementation:

       The CAQM has constituted a sub-committee for the operationalization of the GRAP.

       This body includes officials from the CAQM, member secretaries of pollution control boards of Uttar Pradesh, Delhi, Haryana, Rajasthan, the Central Pollution Control Board, a scientist from the IMD and one from the IITM,

Revision of GRAP

       The CAQM revised the Graded Response Action Plan earlier this year.

       According to the notification, the task of implementing the GRAP fell on the now dissolved Environment Pollution (Prevention and Control) Authority for the NCR. From 2021 onwards, the GRAP is being implemented by the CAQM.

       In the version of the GRAP that was notified in 2017, measures kicked in after pollution concentrations reached a certain level. This year, measures are pre-emptive and will kick in based on forecasts in an attempt to prevent the AQI from deteriorating further.

       The older version of the GRAP was enforced based only on the concentration of PM2.5 and PM10. This year, GRAP is being enforced based on the AQI, which takes other pollutants also into account, such as ozone, sulphur dioxide and oxides of nitrogen.

Stages of GRAP and their restrictions:

Stage 1 (AQI ‘Poor’ – 201 to 300):

       Stopping all construction and demolition activities with plot size of 500 square meters or more which have not been registered on dust mitigation monitoring portals.

       Mechanized sweeping, water sprinkling on roads.

       Enforcing guidelines on use of anti-smog guns at construction sites.

       Enforcing ban on open burning of waste and PUC (pollution under control norms) for vehicles.

       DISCOMs to minimize power supply interruptions in NCR.

       Encourage offices to start unified commutes for employees to reduce traffic.

Stage 2 (AQI ‘Very poor’ – 301 to 400):

       Not allowing coal/firewood in tandoors at hotels.

       Stopping use of diesel generator sets except for essential and emergency services (hospitals, railways, metro services, airports, water pumping stations, “projects of national importance”).

       Enhance parking fees to discourage private transport.

       Augment CNG/ electric bus and metro services by procuring additional fleet and increasing the frequency of service.

Stage 3 (AQI ‘Severe’ – 401 to 450):

       Ban on construction and demolition activities except railway, metro, hospitals, sanitation projects etc, linear public projects like highways, roads, flyovers.

       Closure of industries that have PNG supply and are not running on approved fuels. In industrial areas that don’t have PNG supply, industries not running on approved fuels will operate only for five days a week.

       State governments in NCR may impose restrictions on BS III petrol and BS IV diesel four wheelers.

Stage 4 (AQI ‘Severe +’ – more than 450):

       Stop entry of truck traffic into Delhi (except for essentials, CNG and electric trucks).

       Ban on plying of Delhi registered diesel medium and heavy goods vehicles in Delhi, except for essentials.

       Ban on plying of 4-wheeler diesel vehicles in Delhi and districts of NCR bordering Delhi, except BS-VI vehicles and vehicles used for essential or emergency services.

       State Governments may consider additional emergency measures like closure of schools, plying of vehicles on odd-even basis

       NCR State governments decide on allowing public, municipal and private offices to work on 50% strength and the rest to work from home.
