GRAP-IV curbs revoked in Delhi-NCR amid dip in pollution levels

Commission for Air Quality Management (CAQM) revoked Graded Response Action Plan (GRAP) Stage 4 restrictions across Delhi-NCR amid a dip in pollution levels. However, measures under GRAP Stages-1, 2 and 3 will remain in force to manage pollution levels, CAQM said. Supreme Court had said that GRAP 4 curbs should be immediately implemented if AQI crosses 400 mark.
