Peak and non-peak pollution in Delhi

Dr. Sumit Sharma

30th Nov 2019

IAAPC


Winter pollution is high both in peak and non-peak

periodsData : Lodi Road station 201819 –CPCB website


• Wind speeds in 2019 were 14% less than 2018 (CPCB 15 stations average data)

Comparison between 2018 and 2019Data : Average of 15 stations CPCB website

-2% -3% -9% -7% 3% - 20% -6% +4%


Geographical contributions to Delhi’s PM2.5


Contributing sources in Delhi’s pollution

during winters• Non-peak pollution : Old

vehicles, industries and power plants using solid fuels, biomass burning in kitchens, road dust.

• Peak pollution : Agricultural residue and cracker burning Readjusted numbers based on original

source apportionment study of 2016TERI&ARAI (2018)

• Strategies to address non-peak pollution

Key Messages- Non peak sources

Industry

Shift all industries in NCR to NG

PNG expansion to be expedited in

areas with high pollution load

Industries using existing fuels must

report real time emissions to SPCBs

Encourage industries to shift to

electric route, where feasible.

Enforce Zig-zag tech. in brick kilns to

Zig-Zag firing technologyReduction potential : 11%

Transport

Improve I&M system

Incentivize transition of pre-BSIV

commercial vehicles to BS-VI

Accelerate penetration of

electric busesReduction potential : 19%

Residential

All households in NCR to have

LPG connection by 2019-20.

Two free cylinders to PMUY HHs

(~15 lakhs) during winters.

Double cylinders should be

provided with each PMUY

connection.Reduction potential : 5%

Thermal Power Stations

Notified emission standards to be

enforced in all stations in Delhi – NCR

Shut-down TPS during peak pollution

Use of agricultural residue blendsReduction potential : 3%

Road dust control• Existing machines to be effectively utilised

• Collected dust to be properly managed.

• The new machines (small MRS machine) should preferably be electricReduction potential : 2-3 % PM2.5 , more in PM10


• Strategies to address peak pollution


Key Messages- Peak pollution sources

Crop residue burning

Enable aggregation and collection

Mandate state/national organization (NAFED,HAFED PAIC, etc.) to aggregate

Special credit line for financing farm equipment andworking capital for private sector participation

Create market for briquettes

Mandate co-firing of residues in TPS & include 100%paddy-straw based power plant in merit orderdispatch in Punjab and Haryana

Promote bio-pellets in local industries & hotel/dhaba

Local markets for Bio-gas from straw

Setup local infrastructure to distribute Bio-gas

Dedicated policy and SPV for distribution of Bio-gas

Peak reduction potential : 40%Avg. reduction potential : 6%

Cracker burning

Community (RWA)

celebration of Diwali with

pre-decided quota of

green crackers for each

RWA

RWA can purchase pre-

decided quota from

approved outlets

Ban on sale of crackers to

individuals in Delhi – NCR

Peak reduction potential : 36%


Key open issues

• How do we meet the costs : GREEN Bonds ?

• Industrial competiveness v/s environmental controls

• Capacity of SPCBs and CPCBs

• Air-shed management : coordination between states and

centre

• Public awareness and sensitivity


Innovation needs

• Electric retro fitment of vehicles

• Improvements in battery energy density

• Remote vehicle emission checking

• Low cost technologies for stack and ambient

monitoring

• Indigenous technologies for control of emissions

• Water efficient fog guns for construction dust control

• Low cost masks and purifiers

• Use of satellites and other technologies for vigilance

and enforcement
