On Tuesday, the Supreme Court-appointed EPCA lifted the ban on the entry of heavy vehicles into Delhi on Tuesday, four days after it was imposed due to alarming pollution levels.
The EPCA -- Environment Pollution (Prevention and Control) Authority -- said heavy vehicles would now ply on normal timings between 11 PM and 6 AM.
Delhi is reeling under the menace of air pollution for the past couple of years. The region faced a major air quality crisis last year when severe pollution level forced the shutdown of schools and colleges. In 2016, the government tried to explore the possibility of cloud seeding for artificial rain but the plan never worked out.
