Declaring that controlling Delhi's pollution has become the "requirement of the day", the Supreme Court agreed to formalise in a judicial order a series of directions to impose 'environment compensation charge' on all light and heavy duty commercial vehicles entering the National Capital.

A three-judge bench led by Chief Justice of India in a special sitting at 10.30 a.m. said the formal order imposing the pollution charge would be passed on Monday.

It directed the Delhi government to issue a separate notification in this regard based on the Supreme Court.

The pollution charge would be collected from all 127 entry points into Delhi. The court said the "deterrent" mechanism is an experiment for two months and is subject to any modification after four months.

The court directed neighbouring State governments of Haryana, Rajasthan and Utter Pradesh to fall in line and the respective chief secretaries to co-ordinate with Delhi government.

The series of directions to regulate the entry of trucks into Delhi to combat air pollution was drafted by the Supreme Court's amicus curiae in the case, senior advocate Harish Salve, in consultation with Solicitor General Ranjit Kumar for the Centre and senior advocate Dushyant Dave, representing the Delhi government.

The Supreme Court's order on Monday would super cede all past order on the issue, including a recent one by the National Green Tribunal, imposing additional tax on polluting trucks entering Delhi.

As per the note which will become part of the apex court's judicial order on Monday, environment compenation charge will be imposed at the rate of Rs. 700 for light duty vehicles and two-axle trucks. Three and four axle trucks would be charged Rs. 1300.

Passenger buses, emergency vehicles and vehicles carrying essential commodities would be exempted from payment. The payment would be collected by the toll operator.

"A direction is needed that charges so collected shall be handed over to the Delhi government by the toll operator without any deduction on a weekly basis," the directions said.

The money so collected would be used by the Delhi government to augment public transport and roads, particularly vulnerable users like cyclists and pedestrians.

The direction also said that private toll tax operators should install Radio Frequency Identity system at their own cost at all 127 points. This facility should be installed in nine main entry points which sees 75 per cent commercial traffic by November 2015. CCTVS too have to be installed in the same nine points.
