## ANSWER

MINISTER  OF  STATE  IN  THE  MINISTRY  OF  ENVIRONMENT,  FOREST  AND CLIMATE CHANGE (SHRI KIRTI VARDHAN SINGH)

(a) to (e):

Trial of various new technologies for air pollution mitigation have been conducted such as Air purification  units  developed  by  NEERI  for  traffic  junction  pollution,  dust  suppressant  for construction  sites  and  road  dust  control  developed  by  EPRI,  bus  roof  top  filtration  systems developed by Manav Rachna International Institute of Research & Studies (MRIIRS), medium scale air purification unit (SMOG TOWER) developed by IIT Bombay and Tata Projects Ltd and ionisation  technology  developed  by  S&TP  Pune.  Out  of  all  these  technologies,  results  of  dust suppressant were found encouraging and accordingly advisory issued for its use in Delhi-NCR.

Summary of the project, Sanctioned cost and expenditure incurred on the above mentioned projects is given as Annexure -I.

Central  Pollution  Control  Board(CPCB)  has  notified  the  National  Ambient  Air  Quality Standards  (NAAQS)  in  2009.  The  method  of  measurement  for  all  notified  pollutants  is mentioned in the NAAQS and the ambient air quality monitoring in the country is conducted as  per  the  notified  methodology.  The  revised  National  Ambient  Air  Quality  Standards  is enclosed as Annexure - II.

CPCB Monitors Ambient Air Quality with 15 Continuous Ambient Air Quality Monitoring Stations (CAQMS) comprising 06 in Delhi, 03 in Lucknow, 03 in Bangalore, 03 in Chennai on Real time basis and 07 Manual stations in Delhi. The budget allocation and expenditure over the  past  three  years  for  operation  and  maintenance  of  these  CAQM  stations  is  enclosed as Annexure -III .
