The Supreme Court-mandated Environment Pollution (Prevention & Control) Authority for the National Capital Region EPCA today withdrew the ban on construction activities, entry of trucks and enhanced parking fees from across Delhi-NCR as air quality remained out of the 'emergency' category for the second straight day.<br/><br/>The measures, part of the Graded Response Action Plan, were enforced on November 8 after pollution levels had spiked, hitting the emergency category, accompanied by thick smog.<br/><br/>EPCA chairperson Bhure Lal wrote to the chief secretaries of Delhi, Uttar Pradesh, Punjab and Haryana this morning, directing them that the measures be lifted with immediate effect as the prevailing air quality does not warrant such tough action.<br/><br/>However, measures enforced under the GRAP's 'severe' category including the closure of the Badarpur thermal power plant, ban on brick kilns, hot mix plants and stone crushers will remain, the EPCA said.
