As the national capital is once again choking due to the rising level of air pollution, the EPCA has issued guidelines for governments to stop further deterioration of the environmental conditions. On Tuesday, a thick polluted haze enveloped the NCR, forcing the EPCA to direct governments to impose all conditions under the severe category of the GRAP. This plan is an emergency plan, which cannot become a substitute for long term and decisive action to cut air pollution, said EPCA chairperson. Close all hot mix plants. Close all stone crushers. Immediately intensify public transport service, by ensuring there are more buses on roads, which are run with reliable service. Immediately increase frequency of service of Delhi Metro, including deploying more coaches and introduction of lower fares during off peak hours during this severe period. Immediately enhance parking fee by four times and deposit additional funds in dedicated parking fund with municipalities.
